Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural machinery technology, and in particular to a rice transplanter with film covering for rice planting. Background Technology
[0002] The rice mulching transplanter is an agricultural machine that combines mulching and transplanting. It can cover the paddy field with a biodegradable film before transplanting, which can physically weed by isolating the weeds from sunlight, thereby reducing the use of pesticides. In addition, mulching the paddy field can also improve the water retention of the paddy field, reduce irrigation, and lower irrigation costs.
[0003] Existing mulched rice transplanters require filling seedling trays with seedlings before placing seedlings on a storage rack to replenish the trays. However, these machines cannot automatically replenish the trays with seedlings from the storage rack. As the number of seedlings in the trays decreases, manual replenishment is necessary, which is cumbersome. Alternatively, the machine may stop transplanting after the seedlings in the trays are depleted, requiring frequent stops and significantly impacting transplanting efficiency. Summary of the Invention
[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides a rice transplanter with film covering for rice planting.
[0005] The technical solution is as follows: A rice transplanter with film covering includes a machine head, a trailer frame slidably connected to the machine head, a power component fixedly connected to the trailer frame for driving the machine frame to move, a seedling tray fixedly connected to the machine frame, a film covering roll rotatably connected to the trailer frame and two film-burying wheels, a transplanting component on the trailer frame, a rotating shaft rotatably connected to the machine frame, two turntables fixedly connected to the rotating shaft, a plurality of seedling storage racks rotatably connected between the two turntables, seedling storage racks for storing seedlings, adjustable components on the seedling storage racks, and a support rod fixedly connected to the machine frame for pressing the adjustable components.
[0006] Furthermore, the center of gravity of all the seedling storage frames is located on the side of the rotating shaft closer to the machine head, which is used to orient the rotating shaft.
[0007] Furthermore, the seedling tray is hinged with a blocking frame, which is used to block the seedlings on the seedling storage frame, and a torsion spring is provided between the blocking frame and the seedling tray.
[0008] Furthermore, the support rod is fixedly connected to a mounting bracket, and the mounting bracket is slidably connected to an adjustment bracket, which is used to limit the position of the blocking bracket.
[0009] Furthermore, the seedling tray is slidably connected to a sliding frame, the sliding frame is fixedly connected to several detection plates, a tension spring is provided between the sliding frame and the seedling tray, and a fixing frame is fixedly connected to the sliding frame, the fixing frame being used to adjust the position of the control frame.
[0010] Furthermore, the rotating shaft is fixedly connected to several fixing blocks, the arrangement of the fixing blocks corresponds to the arrangement of the seedling storage frame, the frame is fixedly connected to a fixing frame, the fixing frame is slidably connected to a limiting member, a first spring is provided between the limiting member and the fixing frame, and the limiting member is used to limit the fixing blocks.
[0011] Furthermore, the frame is slidably connected to a transmission component, the transmission component is rotatably connected to a transmission block, the transmission block is used to press the limiting component, the transmission component is fixedly connected to a blocking block, the blocking block is used to limit the transmission block, the sliding frame is fixedly connected to a transmission rod, and the transmission rod and the transmission component press against each other.
[0012] Furthermore, the transmission block is composed of a round rod and a rectangular block, with the upper side of the rectangular block connected to the round rod. The limiting member is composed of a T-shaped frame and a round rod. The horizontal side of the transmission block near the limiting member is higher than the axis of the round rod of the limiting member, while the horizontal side of the transmission block away from the limiting member is lower than the axis of the round rod of the limiting member.
[0013] Furthermore, the adjusting member is slidably connected to the seedling storage frame, the seedling storage frame is rotatably connected to several rollers, the adjusting member is used to stop the rollers, and a second spring is provided between the adjusting member and the seedling storage frame.
[0014] Furthermore, the roller surface is coated with a friction material to increase the friction between the seedling and the roller.
[0015] The beneficial effects are as follows: This invention stores seedlings using several seedling storage racks, and when seedlings on the seedling trays need to be replenished, the seedling storage racks are rotated by adjusting the adjustment components, thereby automatically transferring the seedlings stored on the seedling storage racks to the seedling trays, thus improving the automation level of the mulched rice transplanter and increasing the working efficiency of the rice transplanter.
[0016] The remaining number of seedlings on the seedling tray is detected by the detection plate. Then, the transmission blocking frame releases the obstruction of the seedlings, allowing the seedlings to be transferred from the seedling storage rack to the seedling tray. At the same time, the transmission limit component releases the obstruction of the fixed block, causing the rotating shaft to rotate and the next seedling storage rack loaded with seedlings to enter the unloading state. This achieves continuous replenishment of seedlings and ensures the working efficiency of the rice transplanter.
[0017] By placing the seedlings on the rollers, the friction between the seedlings and the seedling storage rack is reduced, making it easier to unload the seedlings. The rollers are also compressed by the adjusting parts to prevent them from rotating randomly, thereby improving the stability of the seedlings when they are stored on the seedling storage rack and making them less likely to fall off.

Detailed Implementation
[0020] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
[0021] Example 1: A rice transplanter with film covering for rice planting, such as Figures 1-3As shown, the machine includes a machine head 1, with a trailer 101 on the right side of the machine head 1. The trailer 101 is slidably connected to a frame 2, and a power component is fixedly connected to the trailer 101. The power component is used to drive the frame 2 to move. A seedling tray 3 is fixedly connected to the frame 2. The seedling tray 3 can hold up to six seedlings and is used to store seedlings that will be planted in the paddy field. The trailer 101 is equipped with a film covering roll 4 and is rotatably connected to two film burying wheels 5. The film covering roll 4 releases the film, and then the two film burying wheels 5 bury the edge of the film into the paddy field, thereby achieving film covering of the paddy field. The trailer 101 is equipped with a transplanting component 6, which is used to insert the seedlings at the bottom of the seedling tray 3 into the paddy field. As the number of seedlings at the bottom of the seedling tray 3 decreases, the seedlings on the seedling tray 3 will move downwards to replenish them, so that the transplanting component 6 can continuously insert the seedlings into the paddy field. In the process of the rice transplanting component 6 inserting the rice seedlings into the paddy field, the power component drives the frame 2 to move back and forth, and the frame 2 drives the seedling tray 3 to move back and forth, so that the seedlings on the seedling tray 3 are consumed evenly. The frame 2 is rotatably connected to the rotating shaft 7, and the rotating shaft 7 is fixedly connected to two front and rear turntables 8. Five seedling storage racks 9 are rotatably connected between the two turntables 8. The seedling storage racks 9 are used to store seedlings to replenish the seedlings in the seedling tray 3. The seedling storage racks 9 can hold up to six seedlings and correspond to the seedling tray 3. The seedling storage racks 9 are equipped with adjustment components 10. The frame 2 is fixedly connected to two support rods 11. The support rods 11 are used to squeeze the adjustment components 10. When the turntables 8 drive the seedling storage racks 9 to rotate, the adjustment components 10 are limited by the support rods 11 and drive the seedling storage racks 9 to rotate, thereby tilting the seedlings on the seedling storage racks 9 down. The turntable 8 is divided into six equal parts, and the five seedling storage racks 9 are located on five of these parts. The lower right point is initially left empty, so that the center of gravity of all the seedling storage racks 9 is located on the left side of the rotating shaft 7, so that the rotating shaft 7 can rotate counterclockwise. This allows the rotating shaft 7 to rotate without power. The weight of the seedlings on the seedling storage racks 9 is greater than their own weight, so that when the empty point on the turntable 8 is rotated to the left side, the rotating shaft 7 can still rotate counterclockwise.
[0022] like Figure 4 and Figure 5 As shown, the seedling tray 3 is hinged with a blocking frame 12. The blocking frame 12 is used to block the seedlings on the lower seedling storage frame 9, so that the seedlings on the seedling storage frame 9 will not immediately move to the seedling tray 3 after the position of the seedling storage frame 9 changes. Instead, the seedlings on the seedling storage frame 9 will move when the seedlings in the seedling tray 3 need to be replenished. A torsion spring 13 is provided between the blocking frame 12 and the seedling tray 3.
[0023] like Figure 2 , Figure 4 and Figure 5As shown, the two support rods 11 are fixedly connected to the mounting frame 14. The mounting frame 14 is slidably connected to the control frame 15. The control frame 15 is used to limit the blocking frame 12. The elastic force of the torsion spring 13 is only sufficient to reset the blocking frame 12. When the blocking frame 12 is squeezed by the seedlings, the blocking frame 12 will rotate and the torsion spring 13 will store force. The blocking of the control frame 15 will prevent the blocking frame 12 from rotating when squeezed by the seedlings.
[0024] like Figure 2 and Figure 4 As shown, a sliding frame 16 is slidably connected to the seedling tray 3. The sliding frame 16 passes through the seedling tray 3 and is fixedly connected to six detection plates 17. The seedling tray 3 has six slots, and the detection plates 17 are located in the corresponding slots. The detection plates 17 are composed of two straight plates of different sizes with an included angle. The right straight plate of the detection plate 17 is initially flush with the bottom of the corresponding slot on the seedling tray 3. When the detection plate 17 protrudes from the right side of the seedling tray 3, the edge of the left straight plate of the detection plate 17 will not exceed the bottom of the slot on the seedling tray 3, so that the seedlings will not be stuck by the detection plates 17. A tension spring 18 is provided between the sliding frame 16 and the seedling tray 3. The tension spring 18 is initially in a stretched state. At this time, the detection plates 17 are squeezed by the seedlings. Two fixed frames 19 are fixedly connected to the sliding frame 16. The two fixed frames 19 are used together to adjust the position of the control frame 15. There is a through slot in the middle of the fixed frame 19. The control frame 15 slides in the slot of the fixed frame 19. When the fixed frame 19 moves, it will squeeze the control frame 15, causing the control frame 15 to move back and forth.
[0025] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the rotating shaft 7 is fixedly connected to five fixing blocks 20 at the front and five at the back. The arrangement of the fixing blocks 20 corresponds to the arrangement of the seedling storage frame 9. Six equal division points are set on the edge of the rotating shaft 7, and the five fixing blocks 20 are located on five of these points. The lower right point is left empty. The frame 2 is fixedly connected to two fixing frames 21. The fixing frame 21 consists of a rectangular plate and a rectangular rod. The rectangular plate of the fixing frame 21 is fixed to the frame 2. The rectangular rod of the fixing frame 21 is slidably connected to a limiting member 22. A first spring 23 is provided between the limiting member 22 and the fixing frame 21. The limiting member 22 is used to limit the fixing blocks 20, so that the rotating shaft 7 cannot rotate.
[0026] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the frame 2 is slidably connected with two transmission components 24, and the transmission components 24 are rotatably connected with a transmission block 25. The transmission block 25 is used to press the limiting component 22. The transmission component 24 is fixedly connected with a blocking block 26, which is used to limit the transmission block 25. So when the transmission block 25 presses the limiting component 22 and causes the limiting component 22 to move, the transmission block 25 will not continue to rotate. The sliding frame 16 is fixedly connected with two transmission rods 27. The transmission component 24 has a through groove. The transmission rod 27 slides in the groove of the transmission component 24. The transmission rod 27 and the transmission component 24 press against each other, so that when the transmission rod 27 moves, it can drive the transmission component 24 to move left and right. The transmission block 25 consists of a round rod and a rectangular block. The upper side of the rectangular block is connected to the round rod, and the side opposite to this side hangs down. The limiting member 22 consists of a T-shaped frame and a round rod. The right horizontal side of the transmission block 25 is higher than the axis of the round rod of the limiting member 22, and the left horizontal side of the transmission block 25 is lower than the axis of the round rod of the limiting member 22. Thus, when the transmission block 25 moves to the right, the lower part of the right horizontal side of the transmission block 25 can press the round rod of the limiting member 22, causing the limiting member 22 to move downward. When the transmission block 25 moves to the left, the upper part of the left horizontal side of the transmission block 25 is blocked by the round rod of the limiting member 22, causing the transmission block 25 to rotate without pressing the limiting member 22 to move.
[0027] When using this device for rice transplanting, first fill the seedling tray 3 with seedlings, and then fill the seedling storage rack 9 with seedlings, including the lowest inclined seedling storage rack 9. At this time, the seedlings on the lower seedling storage rack 9 are blocked by the blocking frame 12, so they will not fall. Then, the machine head 1 can be started to enter the paddy field for transplanting. During the transplanting process, the film is pulled out from the film covering roll 4, and then the edge of the film is buried into the paddy field by the film burying wheel 5. Then, the transplanting component 6 inserts the seedlings from the lower side of the seedling tray 3 through the seedling tray into the paddy field. As the transplanting proceeds, the seedlings in the seedling tray 3... The seedlings gradually move downwards until the pressure from the seedlings is insufficient to maintain the position of the detection plate 17. At this point, the sliding frame 16 moves under the action of the tension spring 18, pushing the detection plate 17 to bulge off the seedling tray 3. The sliding frame 16 drives the fixed frame 19 to move, and the fixed frame 19 squeezes the control frame 15, causing the control frame 15 to move forward until the control frame 15 is misaligned with the blocking frame 12. At this point, the blocking frame 12 rotates under the pressure of the seedlings, causing the torsion spring 13 to store force. Then, the seedlings in the lower seedling storage frame 9 slide down and enter the seedling tray 3. After the seedlings pass through the blocking frame 12, the blocking frame... 12 returns to its original position under the action of torsion spring 13. At the same time, sliding frame 16 drives transmission rod 27 to move. Transmission rod 27 squeezes transmission component 24. Transmission component 24 drives transmission block 25 to move to the right. Transmission block 25 squeezes limiting component 22, causing limiting component 22 to move downward and compress the first spring 23. At this time, transmission block 25 is limited by blocking block 26 and will not rotate. When limiting component 22 separates from fixed block 20, rotating shaft 7 loses its limit. Because the center of gravity of rotating shaft 7, turntable 8, seedling storage frame 9 and seedlings is located on the left side of rotating shaft 7, rotating shaft 7... 7. Rotate counterclockwise. At this time, the lower edge of the transmission block 25 passes the limiting member 22. The limiting member 22 moves upward under the action of the first spring 23, thereby limiting the second fixed block 20. Then, the transmission block 25 passes the round rod of the limiting member 22 and separates. At this time, the seedlings on the seedling storage frame 9 slide onto the seedling tray 3 and squeeze the detection plate 17, causing the detection plate 17 to drive the sliding frame 16 to move and stretch the tension spring 18. At the same time, the sliding frame 16 drives the fixed frame 19 to move. The fixed frame 19 drives the control frame 15 to return to its original position, thereby limiting the blocking frame 12 again.
[0028] When the rotating shaft 7 rotates, it drives the turntable 8 to rotate, which in turn drives the seedling storage rack 9 to rotate. As the lower seedling storage rack 9 revolves with the turntable 8, it continues to rotate on its own axis because the support rod 11 abuts against the adjusting member 10, until the support rod 11 can no longer abut against the adjusting member 10. At this point, the two separate. Then, the turntable 8 drives the second seedling storage rack 9 to move until the adjusting member 10 on top of it abuts against the support rod 11. The adjusting member 10, being obstructed, gradually drives the seedling storage rack 9 to rotate, causing it to change from a horizontal to an inclined state, preparing to unload the seedlings. At this time, the seedlings are blocked by the blocking frame 12. Simultaneously, the sliding frame 16 drives the transmission rod 27 to move, thus transmitting the seedlings. The rod 27 drives the transmission component 24 to move to the left. The transmission component 24 drives the transmission block 25 to move. The transmission block 25 is blocked by the limiting component 22. Because the left side of the transmission block 25 is lower than the axis of the circular rod of the limiting component 22, the transmission block 25 will rotate during the movement and will not squeeze the limiting component 22 to move. After the transmission block 25 separates from the limiting component 22, the transmission block 25 returns to its original position under the action of gravity. The above process is repeated five times. After the seedlings are exhausted, press down on the limiting component 22, then rotate the turntable 8 to return the turntable 8 to its original position and release the limiting component 22 so that the limiting component 22 re-locks the first fixing block 20. After that, the seedlings can be refilled for transplanting.
[0029] Example 2: Based on Example 1, as follows Figure 3 As shown, the adjusting component 10 is slidably connected to the seedling storage frame 9. The seedling storage frame 9 is rotatably connected to several rollers 28. The adjusting component 10 is used to stop the rollers 28, which facilitate the removal of seedlings from the seedling storage frame 9. A second spring 29 is provided between the adjusting component 10 and the seedling storage frame 9. The second spring 29 is always in a compressed state, providing the adjusting component 10 with a squeezing force on the rollers 28, thereby stopping the rollers 28. The rollers 28 of the four upper seedling storage frames 9 are in a stopped state, thus reducing the probability of seedlings sliding on the seedling storage frames 9. A friction material coating is provided on the surface of the rollers 28 to increase the friction between the seedlings and the rollers 28.
