Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically to a self-propelled integrated transplanter for planting seedlings in a planting pit and its working method. Background Technology

[0002] In the existing technology, seedling transplanters still have the following shortcomings when in use:

[0003] 1. When planting rice seedlings, the height of the raised beds varies, and the rice seedling transplanter cannot be used for transplanting rice seedlings with different widths of raised beds, which leads to an increase in the cost of rice seedling transplanting;

[0004] 2. The height of the transplanting beak cannot be adjusted, and the transplanting depth cannot be adjusted, which is not conducive to the survival of transplanted seedlings;

[0005] 3. Some seedling ridges were too high, causing the chassis of the seedling transplanter to drag on the ground, which reduced transplanting efficiency. Summary of the Invention

[0006] This invention provides a self-propelled transplanter that integrates planting and seedling digging, so as to adjust the wheel spacing to be suitable for planting with different widths of ridges; it can also adjust the gap between the duckbill and the ground and the depth of the planting, thereby improving work efficiency and seedling survival rate.

[0007] Meanwhile, the present invention also provides a working method for a self-propelled transplanter that integrates seedling planting and transplanting.

[0008] The self-propelled transplanter with integrated planting and seedling digging is characterized by including a control unit, a seedling tray unit, a power unit, a planting unit, a duckbill unit, and a walking wheel unit.

[0017] Preferably, the duckbill portion includes an opening and closing duckbill, on which a duckbill opening and closing component is connected; and duckbill movement components are respectively connected to the two opening and closing duckbill pieces.

[0018] In the aforementioned duckbill motion assembly, an outer cam plate and a connecting rod two are coaxially connected in the transmission box. A connecting plate one is shaft-connected to the connecting rod two. A left connecting arm and a connecting support arm are shaft-connected to the connecting plate one. A duckbill opening and closing front support arm is also coaxially connected to the connecting support arm.

[0019] The other end of the left connecting arm is connected to the left side plate of the duckbill opening and closing frame; on the upper side of the left side plate of the duckbill opening and closing frame, the connecting arm is coaxially connected to the duckbill opening and closing support arm.

[0020] After the duckbill opens and closes, the front side of the support arm is hinged to the duckbill opening and closing rod. The other end of the duckbill opening and closing rod is hinged to the front support arm of the duckbill opening and closing. The other end of the front support arm of the duckbill opening and closing is connected to the support shaft one. The outer cam of the two cam plates rotates to contact the support shaft one.

[0021] After the duckbill opens and closes, the rear side of the support arm is connected to the ball joint connecting rod, and the other end of the ball joint connecting rod is connected to the duckbill opening and closing support arm;

[0022] On the other side of the connecting plate, there is a left connecting shaft intermediate plate coaxially connected to the left connecting arm, and the other end of the left connecting shaft intermediate plate is shaft-connected to the transmission box.

[0028] The working method of the self-propelled seedling transplanter provided by this invention is as follows:

[0029] The gasoline engine in the power unit transmits power from the drive wheel and drive shaft, and the drive shaft transmits the power to the gearbox. The driven drive shaft in the gearbox drives the front wheels to move.

[0030] The drive wheel transmits power to the transmission box, and the gears in the transmission box transmit power to the gearbox in the seedling tray, which drives the seedling cup connecting plate to rotate, thereby driving the seedling cup to move. When the seedling cup rotates to the seedling dropping notch position, the seedling falls from the seedling cup into the duckbill.

[0031] At the same time, the transmission box drives the pond digger to fall and dig, and then raises the pond digger again; simultaneously, the transmission box drives the duckbill to fall, and the inner cam plate touches the second support shaft; thus opening and closing the duckbill. As the duckbill falls to the ground, it moves backward a distance, and the outer cam plate touches the first support shaft, thus opening and closing the duckbill.

[0032] The beneficial effects of this invention are:

[0033] 1. In this invention, the power unit is located on the front side of the machine and the working part is located on the rear side of the machine, which facilitates observation of the transplanting of seedlings and ensures the quality of seedling transplanting.

[0034] 2. The design of the lifting and adjusting screw structure allows the distance between the rear wheel support rod and the control panel connecting pipe to be adjusted, thereby driving the ground clearance of the duckbill and the height of the pond digger, thus adjusting the transplanting depth and pond digging depth; suitable for transplanting more types of seedlings and transplanting work with different ridge heights.

[0035] 3. The seedling tray is fixed on the connecting pipe of the control panel. When adjusting the height of the transplanter, the seedling drop position of the seedling tray is synchronized with the position of the duckbill, so as not to affect the drop of the seedling.

[0036] 4. Both the front and rear wheel tracks are adjustable to accommodate planting ridges of varying widths; the front wheels are mounted via a gearbox, increasing ground clearance; the rear wheels can be height-adjusted via support rods, thus overcoming the problem of the chassis dragging on the ground.

[0037] 5. After the pond-digging section is disassembled, the whole machine has a transplanting function, which is convenient for transplanting plots with different planting patterns;

[0038] 6. The handlebars are height adjustable for easier operation. Attached Figure Description

[0071] Based on the structure of Embodiment 1, the seedling tray includes a base 6.1, a seedling cup 6.2, and a seedling cup connecting plate 6.3; the seedling cup 6.2 is fixed on the seedling cup connecting plate 6.3, the base 6.1 contacts the seedling cup 6.2, and a seedling drop notch 6.11 is provided in the base 6.1; the lower side of the seedling drop notch 6.11 is a duckbill inlet; the seedling cup connecting plate 6.3 is connected to a gearbox 6.4, which is connected to a transmission box 2 to provide power. Example 3

[0072] Based on the structure of Embodiment 1, the walking wheel part includes a front wheel 8 and a rear wheel 9. The front wheel 8 is located below the power part 5. The power part 5 is connected to a drive shaft, and the drive shaft is connected to a gearbox 13. The front wheel 8 is installed on the driven shaft in the gearbox, and the front wheel 8 is mounted on the drive shaft 10 in an adjustable position.

[0074] The working method of the self-propelled seedling transplanter provided by this invention is as follows:

[0075] The gasoline engine in the power unit transmits power from the drive wheel and drive shaft, and the drive shaft transmits the power to the gearbox. The driven drive shaft in the gearbox drives the front wheels to move.

[0076] The drive wheel transmits power to the transmission box, and the gears in the transmission box transmit power to the gearbox 6.4 in the seedling tray section, which drives the seedling cup connecting plate 6.3 to rotate, thereby driving the seedling cup 6.2 to move. When the seedling cup rotates to the seedling dropping notch 6.11, the seedling falls from the seedling cup into the duckbill.

[0077] Simultaneously, the transmission box drives the seedbed applicator to descend and fill the seedbed, and then raises it again. At the same time, the transmission box also drives the beak applicator to descend, with the inner cam plate contacting the support shaft 7.23. This allows the beak applicator 7.1 to open and close. As the beak applicator 7.1 falls to the ground, it moves backward a short distance, thus offsetting the longer forward movement and ensuring the correct planting distance for the seedlings. The outer cam plate 7.11 contacts the support shaft 7.10, thereby opening and closing the beak applicator.

[0078] In the specific transmission process, the power output shaft 2.1 drives the third arm 3.5 of the digger to rotate, which in turn drives the second arm 3.4 of the digger, causing the first arm 3.3 of the digger to rotate around its connection point with the transmission box plate shaft, thus driving the upright rod 3.2 and the digger 3.1 to move up and down. At the same time, the power output shaft 2.1 drives the right arm 7.21 and the short connecting arm 7.20 to move, and the middle plate 7.15 of the right connecting shaft drives the right connecting arm 7.16, the middle plate 7.14 of the left connecting shaft, and the second connecting rod 7.2 to drive the left connecting arm 7.4 to move around the shaft connection point, thus realizing the lowering and raising of the duckbill. In addition, during the rotation, the inner cam plate touches the second support shaft 7.23, which causes the duckbill to move backward when it falls, and the outer cam plate 7.11 touches the first support shaft 7.10, which drives the duckbill opening and closing support arm 7.13 to pull the wedge block up and down, thus realizing the opening and closing of the duckbill.
