First, the main structure and principle of hand transplanter
The hand transplanter is mainly composed of an engine control system, a driving operation system, a planting system, an oil pressure system, and a walking system.
Its working principle is as follows:
The operation of the planting arm drives the picking work, removes the seedling from the seedling plate, and then uses the pusher to insert the seedling into the ground so that the transplanting can be completed.
Second, hand-pulling transplanter installation and start
In order to be able to use the rice transplanter correctly in order to achieve stable production and high yield, it is necessary to correctly grasp the operation and use of the rice transplanter. First you need to open the random box and verify the accessories according to the list of parts inside. Among them, the middle benchmark and the preparation of the seedling tray are required for your own installation. Below, we will introduce you to the installation method.
The first thing to do is to find the center bar, which can be fixed directly to the front of the machine. Then begin to assemble the preparatory seedlings. The first step: the spring is assembled on the guide rod in the correct direction. Afterwards, the guide rod is fixed on the seedling tray bracket; the second step is to fix the front roller of the seedling tray frame, and then when loosening the seedling tray frame to the transplanter, loosen the bracket fixing plate on the guide rod and put the two The rear roller is mounted on a bracket guide. Next, the seedling tray is placed on the holder guide, the holder fixing plate is fixed, and the last two front rollers are installed. In this way, the seedling trays are assembled, and after doing a good job, do not forget to use your hands to check if the assembly is in place. Your machine is now a complete machine.
Let's take a look at how to operate this transplanter. Before starting the machine, check whether the engine oil and fuel are sufficient. If there is not enough, we must make up. Then open the fuel tank cap, add the appropriate amount of pure gasoline, there must be no open flame when refueling, put the fuel switch in the open position.
You are now ready to start the rice transplanter. Place the shift lever in neutral and start the switch to the operating position. If it is night, place it in the lighting position. Then gently pull out the throttle handle. The main clutch and the rice transplanter clutch are moved to the "off" position and the oil pressure handle is in the "down" position. And adjust the throttle handle to the inside 1/2. Then, pull the recoil starter, start the engine and push the damper back. Raise the machine, set the shift lever to the walking or planting gear, slowly connect the main clutch, and the machine can walk. When walking in Daejeon, in order to prevent bumps, you can put the gearshift lever in the plug and slowly transfer the machine.
Third, the operating method
1. Preparation
When the conditions of the plots or the conditions of the seedlings do not match the transplanting operations, the quality of the work will be reduced. Therefore, the first requirement is that the plots be relatively flat, with a depth of 13-15 cm. The optimum depth of water is about 20 cm. If the water is too deep, the first-planted seedlings will be washed out when transplanting. The water will be shallow or not. Water, claws may bring back seedlings. The plots are ready. Let's see what kind of seedlings are best for transplanting.
Seedlings require uniform sowing. The height of the seedlings generally requires 12-18 cm, the seedlings grow to 3 leaves, and the seedlings can be transplanted with at least 3.5 leaves. At the same time, it is required that the packing is relatively tight and not easy to loose, and the thickness of the soil layer is about 2.5 cm. At the same time, seedlings should not be too watery, and suitable seedlings will have water stains when they are hand-smashed under the earth. Basically, the soil moisture content is between 30% and 40%. When taking seedlings, seedlings must be used so as not to harm the seedlings.
When you enter the plot, you have to enter from one corner of the plot. It is best to leave the width of the two machines to facilitate turning. The hydraulic handle should be placed in the "down" position and the machine lowered. The following will be installed seedlings.
2, operation method
Before installing the seedlings, the shift lever should be placed in the neutral position, the oil pressure handle should be set to drop, the engine should be started, the main clutch and the planting clutch should be connected so that the seedling box can be moved to the left or right of the guide rail, and the seedlings can be pulled out after the flameout. board. Use seedlings to load seedlings. The seedlings should be mounted on the leading edge of the guide rails, with no gaps or pressure on the guide rails. A few plates of seedlings can be placed on the pre-seedlings for easy supply. If the block is too dry, sprinkle it with a little water to make it moist, making it easier for the block to slip.
After the seedlings are installed, the machine is started, the shift handle is set to the insertion position, and the plug-in clutch is connected, and then the seedling box starts to move. Special attention should be paid to the fact that the transplanter is provided with a marker and a side aligner, which is set to keep the line spacing consistent. There are two side-to-side positioners, one with a row spacing of 33 cm and one with a length of 30 cm, which can be moved to a suitable location according to the requirements of the job. We are planting indica rice here, generally 30 cm. Unfold the marker and, at the same time, align the adjacent side of the seedlings or bales. Finally, the main clutch is slowly connected to start the insertion.
When the machine is working for the first time, you can try to insert a distance and check whether the seedling transplanting depth and the amount of seedlings meet the requirements. Here, the amount of seedlings taken is generally in accordance with 3-5 strains per hole of indica rice (subscript-hybrid rice 1-2 strains per hole). The seedlings were inserted at a depth of 2.6 cm and the spacing between the plants was 12 cm (subtitles - 20 cm in hybrid rice plants), and the row spacing was fixed at 30 cm.
When working in the field, the transplanting procedure should be considered to minimize the area for manual transplanting. According to the size and shape of the transplanting operation field, it is necessary to plan the route of the operation before the operation, and then effectively complete the transplanting operation. Whether it is a quadrangular field or a shaped field, it is best to leave the two corners of the machine at four corners for easy turning. Finally, just make sure that each row in the field is full of rice.
If the seedlings are not inserted straight, you can hold the handle at any time to move the machine left and right for the purpose. (Subtitles - can not hold the clutch, otherwise it will make the machine turn.) When transplanting, the operator must take a catwalk, can not walk legs apart, otherwise it will lead to machine imbalance, affecting the transplanting effect. The throttle handle can be gradually increased to increase the speed of the job.
If you need to turn, lower the engine's speed, cut the plug clutch handle, retract the marker, and hold the side clutch turning in the direction of rotation. Note: The width of one machine should be left before turning. After the rotation is completed, connect the handle of the insertion clutch, open the marker, and continue the operation. (Subtitle --- If the line drawn by the marker is not clear, use the side-to-side device directly)
The seedlings on the seedling box are limited, and the seedlings must be supplied before the seedlings reach the seedlings supply position. The following describes how to supply seedlings. Place both the main clutch and the plug-in clutch in the cut-off position, and pull the pre-seedling holder to the body and adjust it to a position convenient for replenishment. Put the seedlings slowly into the seedling box. Note that the seedlings must be aligned with the remaining seedlings. There must be no gaps, and they must not be overlapped. After the seedlings are supplied, the prepared seedling support is pushed back. Continue working. Basically, 18 sprouts per acre are needed.
When the remaining seedlings of the seedling box are cleared after the rice transplanting operation is completed, the pressure seedlings are fixed upward and then the seedlings are removed.
Fourth, hand-held transplanter adjustment
When the rice transplanter is working, how to ensure the quantity of seedlings, plant spacing, and planting depth is a concern for each user. How to solve these problems? We first look at the regulation of the amount of seedlings.
1, take the adjustment of the amount of seedlings
Handle seedling transplanter can be divided into seedling quantity adjustment, longitudinal seedling quantity adjustment and lateral seedling quantity adjustment.
The amount of seedlings taken in the longitudinal direction mainly refers to the height range of the cut needle block. The adjustment range is 8-17 mm and the standard is 11 mm. If the amount of seedlings is too large or too small, adjust the nut on the upper end of the roll by the seedlings. The upward adjustment of the screw, that is, the downward adjustment of the nut, takes a larger amount of seedlings, and vice versa.
The amount of seedling taken in the transverse direction refers to the number of movements of the planting arm when the seedling box is moved from one end to the other end. Its adjustment has three gears, 20, 24, and 26. Usually, according to the size of the seedlings, the big seedlings should be placed in the 20 stalls, the middle seedlings 24, the seedlings 26. Here we put it in 24 position. When adjusting, be sure to correspond with the seedling transfer fork combination.
2, spacing adjustment
In the gear box on the right side of the shift between the shift handle, a total of six-speed adjustment, from outside to inside are: 12,14,16 one and 17,19,21 one (subtitles - all data refers to centimeters). When the shift lever is in the first gear position, the corresponding plant spacings are 12, 14, and 16, respectively, for planting the indica rice; when the shift lever is in the second shifting position, the corresponding plant spacings are respectively 17, 19, and 21. Used for transplanting hybrid rice. The distance from the factory is the middle range, which is 14 or 19.
If you want to change the inserting density, you can adjust the gear position. The adjustment method is as follows: the shift lever is in the neutral position, the main clutch and the insertion clutch are engaged, and the planting arm is operated at a slow speed. Push or pull the spacing between the handles, adjust to the desired position, and then increase the throttle, so that the planting arm at high speed, confirm the phenomenon of no gear stalls can be.
