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 position, the corresponding plant spacings are 12, 14, and 16, respectively, for planting the indica rice; when the shifting lever is in the second shifting position, the corresponding plant spacings are 17, 19, and 21, respectively. 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. Adjustment method

The shift lever is in the neutral position, the main clutch and the insertion clutch are engaged, and the implanting 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.

3, transplant depth adjustment

The insertion depth can be selected by changing the position of the insertion depth adjustment handle; 4 positions can also be selected by changing the position of the mounting plate at the back of the floating plate, and 6 positions can be selected, the above holes can be inserted, and the insertion depth can be shallower; The hole below is deep and deep. When adjusting the positions of the mounting plate holes, it is necessary to ensure that the positions of the three floating plate mounting holes are the same. The depth of transplanting can be determined according to the agronomic requirements. Under normal circumstances, it does not float, and the shallower the better. Here we use the seedlings, the standard depth of transplants can be 5 mm -1 cm, insert depth adjustment handle for every shift 1 position, the depth of the transplant will change about 6 mm.

After the rice transplanter is used for a period of time, some parts of the rice transplanter will run loose and wear out due to frequent operation, thus affecting the quality of transplanting. Therefore, it is necessary to adjust the rice transplanter in time to make it work better. Let's look at the adjustment of the cable section.

1, adjust the cable

The main parts that need to be adjusted are the following sections:

Adjustment of the steering cable (gray): The steering cable can be adjusted when the rice transplanter turns instable or turns in place. Adjust the adjusting screw on the pull wire so that the gap of the steering handle can be adjusted to 1 mm. The adjustment method for left and right steering cables is the same.

Adjustment of the main clutch cable (yellow): When the rice transplanter is unable to walk or the main belt is worn, the main clutch cable can be adjusted. Adjust the adjustment nut on the pull cable so that when the main clutch handle is connected to the “OFF” position, the power starts to transfer or the implanting arm starts to operate. This position is the best.

Adjustment of the pull-out clutch cable (green): When the planting part cannot be combined and separated properly, adjust the pull-out of the pull-out clutch and adjust the nut on the pull-wire. When the main clutch is connected, the handle of the pull-out clutch is inserted in the position of the cut-off position. The arm starts to operate and this position is optimal.

Hydraulic clutch cable adjustment method (blue): When the machine is not sensitive to rise or fall, check the hydraulic clutch cable. When the throttle is opened to the maximum, the main clutch and the insertion clutch are cut off. When the adjustment nut on the hydraulic clutch is adjusted so that the handle is in the “up” position, the machine can rise in 3 to 4 seconds, and it can fall in 0 to 2 seconds. It must be "fixed" after coming up. This is the best position. If the line is too tight, it will rise quickly and decline slowly; if the line is too loose, it will rise slowly and fall faster.

2, planting system adjustment

In addition to the need to adjust the pull line, the transplanter after a long time, especially planting system, prone to loosening, wear, etc., also need to check and adjust.

First, it should be checked whether the needle and pusher are deformed. If it is deformed, use a screwdriver to push the needle up or down and adjust it until the gap between the needle and the pusher reaches 0.7-2mm.

The second step is to check if the gap between the needle and the seedling is the same. If the picking needle is not in the middle of the picking mouth, it will easily deform the picking pin, aggravate the wear of the rubber guide plate, and affect the quality of the picking pin. The adjustment method is: loosen the nut on the inserted crank pin, knock loose the crank pin, loosen the nut on the rocker, adjust the planting arm, if not, loosen the nut on the rocker, increase or decrease the pad sheet. If the needle needs to move inward, reduce the spacer. If the needle needs to move outwards, increase the spacer. Lock each nut when the needle is in position.

The third step is to use the seedling calipers to check the needles on the four implant arms, and whether or not they are on the same level as the navigation. If not, it will affect the control of the amount of picking per hole, the adjustment method is: first adjust the left planting arm. Place the vertical pick handle on the standard gear and loosen the bolt on the adjustment gear plate. Move the adjusting gear plate so that the guide rail moves up and down until the longest mark on the caliper needle is aligned. Then adjust the right planting arm. Adjust the adjusting nut on the right side of the guide so that the guide moves up and down so that the longest mark on the caliper can be aligned with the guide. Finally adjust the two planting arms on the inside. Loosen the lock nut on the rocker and tap the rocker with a hammer. The planting arm moves up and down so that the longest scale line on the pick and the gauge can be aligned.

In the fourth step, check the side clearance between the seedling box and the picking needle. When the seedling box moves to the most “left” or “right” end, the four picks cannot be rubbed against the side of the seedling box. If friction occurs, it is easy to deform the needle, affecting the quality of the transplant. When adjusting, loosen the nut of the seedling box support arm at both ends of the seedling box, and gently knock the seedling box support arm to place it. Tighten the nut last.

After the inspection and adjustment according to the above method, the planting system can return to normal.

3, other adjustments

In addition, there are several sections that need to be properly adjusted.

Belt adjustment: After a period of time, the belt may loosen and the standard belt should be on the same level as the side. It is best to press the belt with a fall of 10-15 mm. If it is loose, push the engine forward to tension the belt, and vice versa.

Adjustment of body balance: If the left and right sides of the transplanter are unbalanced, the inserted depths of the left and right sides of the seedling will be inconsistent. Just adjust the profile adjustment bolts under the cover.

The tension adjustment of the drive chain of the planting department: After starting the machine, if there is a buzzing noise in the middle body frame assembly, it indicates that the drive chain of the planting department is loose and should be tightened in time. It is possible to slightly unscrew the fixing bolts and adjust the tension plate downwards until there is no sound.
