Description

Technical Field

[0001] This utility model relates to the field of rice transplanter technology, and in particular to an automatic rice transplanter for feeding seedlings. Background Technology

[0002] As an important tool in modern agriculture, rice transplanters not only ensure the quality of rice transplanting but also significantly improve operational efficiency, save manpower, and thus reduce labor costs.

[0003] The relevant rice transplanters typically transfer seedling blocks to the transplanting device, and then continuously transplant seedlings as the transplanter moves. Patent CN109937656A discloses a high-speed rice transplanter, a high-speed seedling delivery method, and a high-speed transplanting method. The seedling delivery unit 22 transfers seedling blocks to the sorting unit 223 via the conveying body 221, and then the sorting unit 223 arranges the seedling blocks into the seedling channel 311 of the transplanting device 30.

[0004] The aforementioned conveying body 221 is implemented as a conveyor belt, that is, the seedling blocks are conveyed to the sorting section 223 by the conveyor belt. However, when the front end of the seedling block falls into the sorting section 223, the sorting section 223 will generate resistance towards the conveyor belt, while the rear end of the seedling block is still conveyed towards the sorting section 223 by the conveyor belt.

[0005] Therefore, the rear end of the seedling block will compress the front end, causing the seedling block to be compressed and potentially damaging its structure. If the seedling block is damaged, the seedlings will be unevenly distributed, affecting the quality of transplanting. Utility Model Content

[0006] The summary section of this utility model is intended to briefly introduce the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0008] Some embodiments of this utility model provide an automatic rice transplanter with seedling loading, including a transplanting cart, a seedling loading device disposed on the upper end of the transplanting cart, and a transplanting mechanism disposed at the rear of the transplanting cart, wherein...

[0009] The rice seedling loading device includes two fixed frames fixed to both sides of the rice transplanter. Each fixed frame is fixed from bottom to top with a bottom conveyor belt and an upper conveyor belt for transporting seedling blocks.

[0010] The rice seedling loading device also includes a rice seedling receiving mechanism, which includes a rice seedling receiving conveyor belt with its first end hinged to the rice transplanter, a first drive assembly disposed at the bottom of the rice seedling receiving conveyor belt, and a second drive assembly connected to one side of the rice seedling receiving conveyor belt. The rice seedling receiving conveyor belt rotates at the same speed as the bottom conveyor belt and the top conveyor belt.

[0011] The first driving component is used to move the rice-receiving conveyor belt to be coplanar with any of the underlying conveyor belts;

[0012] The second drive component is used to lift the seedling receiving conveyor belt and is coplanar with the upper conveyor belt.

[0013] Optionally, the seedling receiving mechanism further includes a first telescopic rod and a support plate. The bottom of the support plate is connected to the first drive assembly. The two ends of the first telescopic rod are hinged between the seedling receiving conveyor belt and the support plate, and the first end of the seedling receiving conveyor belt is hinged to the support plate.

[0014] Optionally, the first drive assembly includes a first lead screw motor and a first lead screw connected to each other. The first lead screw is rotatably arranged along the width direction of the rice transplanter, and the bearing plate is fixedly connected to the lead screw nut sleeved on the first lead screw.

[0015] Optionally, the front and rear ends of the bottom of the support plate are fixed with guide rail grooves arranged along the width direction of the rice transplanter.

[0016] Optionally, the rice transplanter is equipped with guide rails corresponding to the two guide rail slots. In the assembled state, the two guide rail slots and the two guide rails are slidably connected.

[0017] Optionally, the second drive assembly includes a support frame, a second lead screw, and a second lead screw motor. The second lead screw motor is fixed to the top of the support frame, the top of the second lead screw is connected to the second lead screw motor, and the lower end of the second lead screw passes through the support frame in a vertical direction and is connected to the bearing plate.

[0018] Optionally, another lead screw nut is fitted onto the second lead screw, and the lead screw nut is fixedly connected to the bearing plate.

[0019] Optionally, the second drive assembly further includes a connecting plate, which is fixedly connected to a lead screw nut fitted onto the first lead screw.

[0020] Optionally, the lower end of the support frame and the second lead screw is connected to the connecting plate.

[0021] Optionally, the rice transplanting mechanism includes multiple inclined slides, each slide having multiple rotatable sliding wheels at its upper end to reduce friction during rice seedling transfer, and each slide having a rice transplanting component at its lower end.

[0022] The above embodiments of this utility model have the following beneficial effects: the seedling loading device of this utility model can avoid the seedling blocks from being squeezed and damaged, improve the reliability of the seedling loading device in transporting seedling blocks, and ensure the quality of rice transplanting.

[0023] Specifically, the reason why the seedling blocks are squeezed and damaged is that during the process of conveying the seedling blocks to the sorting section, when the front end of the seedling block falls into the sorting section, the sorting section generates resistance towards the conveyor belt, while the rear end of the seedling block is still conveyed towards the sorting section by the conveyor belt, thus causing the seedling block to be squeezed.

[0024] Based on this, in some embodiments of the seedling loading device of this utility model, the bottom conveyor belt, the upper conveyor belt, and the seedling receiving conveyor belt are made coplanar through the first drive component and the second drive component, allowing the seedling blocks to be transported on a flat working surface. Furthermore, the seedling receiving conveyor belt rotates at the same speed as the bottom and upper conveyor belts, ensuring that the seedling blocks experience the same force during transport when received by the seedling receiving conveyor belt. This prevents the seedling blocks from being squeezed and damaged, thus improving the reliability of the seedling loading device in transporting seedling blocks. Attached Figure Description

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please refer to the following first. Figure 1 , Figure 1 This is a schematic diagram of the structure of one embodiment of the automatic rice transplanter of this utility model. Figure 1 As shown, the automatic rice transplanter of this utility model includes a rice transplanter 1, a rice loading device, and a rice transplanting mechanism 6. The rice loading device is installed on the rice transplanter 1, and the rice transplanting mechanism 6 is installed at the rear of the rice transplanter 1.

[0040] The aforementioned rice seedling loading device includes two fixed frames 2 fixed to both sides of the driver's seat of the rice transplanter 1. Each fixed frame 2 has a bottom conveyor belt 3 and an upper conveyor belt 4 fixed from bottom to top. The bottom conveyor belt 3 and the upper conveyor belt 4 are used to place the seedling blocks 7 before transplanting.

[0041] The aforementioned bottom conveyor belt 3 and upper conveyor belt 4 have the same structure. Taking the bottom conveyor belt 3 as an example, it includes a drive wheel and a driven wheel arranged at intervals, as well as a belt wound around the drive wheel and the driven wheel. The drive wheel is located close to the front of the rice transplanter 1, while the driven wheel is located away from the front of the rice transplanter 1. Furthermore, the diameter of the aforementioned drive wheel can be larger than that of the driven wheel. In this way, the contact area between the drive wheel and the belt is larger, increasing the friction and thus providing a more stable torque output.

[0042] Please see Figures 2 to 6 , Figure 2 This is a schematic diagram of the structure of one embodiment of the bottom conveyor belt for transporting seedling blocks according to this utility model; Figure 3 This is a schematic diagram of the structure of one embodiment of the rice-receiving conveyor belt of this utility model after it has been flipped. Figure 4 This is a schematic diagram of the structure of one embodiment of the rice-receiving conveyor belt of this utility model after it has been moved. Figure 5 This is a schematic diagram of the structure of one embodiment of the upper conveyor belt for transporting seedling blocks according to this utility model; Figure 6 This is a side view of one embodiment of the rice-receiving conveyor belt of this utility model after it has been flipped. Figures 2 to 6 As shown, near the left side of the fixing frame 2 ( Figure 1 The upper end of the rice transplanter 1 (in the direction of the middle) is provided with a seedling receiving mechanism 5. The seedling receiving mechanism 5 is used to receive the seedling blocks 7 transmitted by the bottom conveyor belt 3 and the upper conveyor belt 4, and transmit the seedling blocks 7 to the rice transplanting mechanism 6 set at the rear of the rice transplanter 1.

[0043] The aforementioned seedling receiving mechanism 5 may include a seedling receiving conveyor belt 51, a first telescopic rod 52, a bearing plate 53, and a first drive assembly 54. The first end of the seedling receiving conveyor belt 51 ( Figure 4The left end of the first telescopic rod 52 is hinged to the support plate 53. Both ends of the first telescopic rod 52 are hinged between the seedling receiving conveyor belt 51 and the support plate 53. The first drive assembly 54 is disposed at the bottom of the support plate 53 to drive the seedling receiving conveyor belt 51 to move along the width direction of the rice transplanter 1, thereby docking with any of the bottom conveyor belts 3.

[0044] The driving wheel of the above-mentioned seedling conveyor belt 51 can also be larger in diameter than the driven wheel, just like the bottom conveyor belt 3 and the upper conveyor belt 4, so that the contact area between the driving wheel and the belt is larger, increasing the friction and thus providing a more stable torque output.

[0045] During the process of receiving seedling blocks 7 by the seedling conveyor belt 51, the aforementioned first telescopic rod 52 drives the seedling conveyor belt 51 to rotate around the hinge shaft, causing the second end of the seedling conveyor belt 51 ( Figure 2 The right end of the seedling block 7 is coplanar with the left end of the bottom conveyor belt 3. Furthermore, the rotational speed of the seedling receiving conveyor belt 51 can be the same as that of the bottom conveyor belt 3. In this way, when the front end of the seedling block 7 is received by the seedling receiving conveyor belt 51, the seedling receiving conveyor belt 51 will move the seedling block 7 at the same speed as the bottom conveyor belt 3, which can prevent the seedling block 7 from being squeezed and damaged, and improve the reliability of the seedling feeding device in transferring the seedling block 7.

[0046] Furthermore, the driven wheel of the seedling receiving conveyor belt 51 can be positioned at the second end of the seedling receiving conveyor belt 51, and the driven wheel of the bottom conveyor belt 3 can be positioned at the left end of the bottom conveyor belt 3. When the seedling receiving conveyor belt 51 and the bottom conveyor belt 3 are coplanar, the transition gap can be made smaller due to the smaller diameter of the driven wheel. In this way, it can be avoided that when the seedling block 7 passes through the above-mentioned transition gap, it will sag due to its own weight due to the excessive transition gap, which will cause the tension at both ends to change (forming an angle), the horizontal tension will be decomposed, and the overall structure of the seedling block 7 will become loose due to insufficient tension.

[0047] like Figure 3 As shown, after the seedling block 7 is completely received by the seedling receiving conveyor belt 51, the first telescopic rod 52 extends, causing the seedling receiving conveyor belt 51 to rotate counterclockwise around the hinge axis. Figure 3 The direction of the seedlings is reversed, and under the transmission action of the seedling receiving conveyor belt 51, the seedling block 7 slides into the seedling transplanting mechanism 6. Finally, the first telescopic rod 52 retracts until the seedling receiving conveyor belt 51 is coplanar with the bottom conveyor belt 3, and continues to receive the next seedling block 7.

[0048] When the right side ( Figure 6 After all the seedling blocks 7 on the bottom conveyor belt 3 (in the middle direction) have been received, the seedling receiving conveyor belt 51 can move to the left through the first drive component 54 and dock with the bottom conveyor belt 3 on the left.

[0049] like Figure 6As shown, the first drive assembly 54 includes a first lead screw 541 and a first lead screw motor 542 connected together. The first lead screw 541 is disposed at the bottom of the support plate 53 along the width direction of the rice transplanter 1. A lead screw nut can be fitted onto the first lead screw 541, and the lead screw nut is fixedly connected to the bottom of the support plate 53. In the working state, the first lead screw motor 542 drives the second lead screw 541 to rotate, so that the lead screw nut drives the rice receiving conveyor belt 51 to move along the axial direction of the first lead screw 542 until it docks with the bottom conveyor belt 3 on the left.

[0050] Furthermore, guide rail grooves are fixed at both ends of the bottom of the support plate 53, arranged along the width direction of the rice transplanter 1. Correspondingly, two guide rails 55 are fixed on the rice transplanter 1. In the assembled state, the two guide rail grooves and the two guide rails 55 are matched one-to-one. In this way, the support plate 53 can move along the guide rails 55, thereby restricting the movement direction of the rice seedling conveyor belt 51 and improving the reliability of the rice seedling loading device.

[0051] After the seedling blocks 7 on both bottom conveyor belts 3 have been received, the seedling receiving conveyor belt 51 continues to transfer the seedling blocks 7 placed on the upper conveyor belt 4. The following transfer... Figure 4 The following explanation uses the seedling block 7 on the upper conveyor belt 4 on the right side as an example. Figure 4 As shown, the above-mentioned seedling receiving mechanism also includes a second drive assembly 56 disposed on one side of the support plate. The second drive assembly 56 includes a support frame 561, a second lead screw 562, and a second lead screw motor 563. The second lead screw motor 563 is fixed to the top of the support frame 561. The top of the second lead screw 562 is connected to the second lead screw motor 563, and the lower end of the second lead screw 562 passes vertically into the support frame 561. Another lead screw nut is fitted on the second lead screw 562, and the lead screw nut is fixedly connected to the support plate 53. In the working state, the second lead screw motor 563 drives the second lead screw 561 to rotate, and the lead screw nut can lift the seedling receiving conveyor belt 51, making it coplanar with the upper conveyor belt 4.

[0052] Furthermore, the second drive assembly 56 also includes a connecting plate 564, which is fixedly connected to a screw nut sleeved on the first screw 541. The lower ends of the aforementioned support frame and the second screw 562 are connected to the connecting plate 564. In this way, when the second screw 562 lifts the seedling receiving conveyor belt 51, the bearing plate 53 can move away from the first screw 541, ensuring the lifting function of the seedling receiving conveyor belt 51, thereby completing the operation of receiving the seedling blocks 7 on the upper conveyor belt 4 and transferring the seedling blocks 7 to the transplanting mechanism 6.

[0053] In addition, by setting a connecting plate 564, the first lead screw 541 can drive the seedling receiving conveyor belt 51 to move horizontally through the connecting plate 564, and then through the lifting operation of the second lead screw 562, the seedling receiving conveyor belt 51 and another upper conveyor belt 4 can be made coplanar.

[0054] Furthermore, a sleeve can be fixed on the bearing plate 53. The sleeve is slidably connected to the support columns at both ends of the support frame 561. This not only restricts the lifting direction of the seedling conveyor belt 51, but also prevents shaking during the horizontal movement of the seedling conveyor belt 51, thus improving the stability of the seedling loading device.

[0055] It should be noted that although the above description and the accompanying drawings are based on the example of setting the second drive component 56 on one side of the carrier plate 53, another second drive component 56 can also be set symmetrically. Those skilled in the art can make adjustments according to the actual situation.

[0056] Similarly, the driven wheel of the upper conveyor belt 4 can be positioned at the left end of the upper conveyor belt 4. When the seedling receiving conveyor belt 51 is coplanar with the upper conveyor belt 4, the smaller diameter of the driven wheel allows for a smaller transition gap. In this way, the overall structure of the seedling block 7 can be prevented from becoming loose due to insufficient tension when passing through the aforementioned transition gap.

[0057] After the seedling receiving conveyor belt 51 has fully received the seedling block 7, the second lead screw 562 drives the seedling receiving conveyor belt 51 to descend, and the first telescopic rod 52 extends, allowing the seedling block 7 to slide into the transplanting mechanism 6. Next, the first telescopic rod 52 retracts, and the second lead screw 562 drives the seedling receiving conveyor belt 51 to rise, so that the seedling receiving conveyor belt 51 is coplanar with the upper conveyor belt 4, and then receives the next seedling block 7, until all the seedling blocks 7 on the upper conveyor belt 4 have been transferred to the transplanting mechanism.

[0058] It should be noted that the seedling receiving conveyor belt 51 can first receive the seedling blocks 7 from the two bottom conveyor belts 3, and then receive the seedling blocks 7 from the two top conveyor belts 4. Alternatively, it can first receive the seedling blocks 7 from the two top conveyor belts 4, and then receive the seedling blocks 7 from the two bottom conveyor belts 3, or the seedling receiving conveyor belt 51 can alternately receive the seedling blocks 7 from the bottom conveyor belts 3 and the top conveyor belts 4. Those skilled in the art can adjust this according to the actual situation.

[0059] Revisit Figure 1 The aforementioned rice transplanting mechanism 6 includes multiple inclined slides 61, each slide 61 having multiple rotatable sliding wheels 62 at its upper end to reduce friction during the transmission of the seedling blocks 7. Each slide 61 has a rice transplanting assembly 63 at its lower end.

[0060] In operation, after receiving seedling blocks 7, the first lead screw 541 aligns the seedling receiving conveyor belt 51 with any of the slide rails 61. Next, the first telescopic rod 52 extends, causing the seedling receiving conveyor belt 51 to rotate to an angle coplanar with the slide rail 61. The seedling receiving conveyor belt 51 then moves the seedling blocks 7 to the slide rail 61, where the transplanting assembly 63 completes the transplanting operation. After all seedling blocks 7 have been transplanted, workers can place them onto the bottom conveyor belt 3 and the upper conveyor belt 4 for subsequent transplanting work.

[0061] It should be noted that those skilled in the art can determine the above-mentioned rice transplanting components based on existing technology, and no limitation is made here.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
