Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly to a sweet potato seedling transplanting mechanism and a transplanting soil covering device. Background Art

[0002] Sweet potato is a high-yielding and adaptable food crop, which is closely related to industrial and agricultural production and people's livelihood. Besides being used as a staple food, the tubers of sweet potato are also important raw materials for food processing, starch and alcohol manufacturing industries. The roots, stems and leaves can be used as excellent feeds. Therefore, sweet potato is a relatively important crop and is widely planted in many regions of China. When planting sweet potatoes, it is necessary to transplant the roots downward into the planting grooves and cover the roots with soil. During automatic planting, the seedlings supplied by the automatic seedling supply device are generally in a horizontal state. Therefore, it is necessary to convert the posture of the sweet potato seedlings before transplanting them into the soil. In the prior art, Patent CN218411694U provides a bare seedling transplanting test bench, which uses a first seedling clamping plate and a second seedling clamping plate to perform the seedling transplanting operation. During the seedling transplanting process, the posture state can be realized, and it has the characteristics of compact structure. In this patent, it is recorded in the specification that the material of the seedling clamping plate can be materials such as metal, plastic, polymer, etc. In actual use, using relatively hard materials such as metal as the material of the seedling clamping plate has the problems that the material is too hard, the deformation area of the seedling clamping plate is too small, the angle of the part that can perform the transplanting operation is small, and the clamping force on the sweet potato seedlings is different when the seedling clamping plate rotates to different angles, which is easy to clamp the sweet potato seedlings; while using relatively soft materials such as rubber as the material of the seedling clamping plate has the situation of insufficient clamping force and unstable clamping. Summary of the Invention

[0003] Object of the Invention: In order to overcome the deficiencies in the prior art, the present invention provides a sweet potato seedling transplanting mechanism and a transplanting soil covering device that can enable the flexible disk to have good deformation ability and strong clamping force at the same time.

[0004] Technical Solution: To achieve the above object, the sweet potato seedling transplanting mechanism of the present invention includes a first bracket and two symmetrically installed flexible disks, and the two flexible disks are arranged in a V shape;

[0005] A through-hole array is formed on the flexible disk, and the through-hole array includes a plurality of through-holes arranged in a circumferential array;

[0006] The through-hole array can ensure the synchronization and reliability of the transmission when the gear meshes with the through-hole;

[0007] The through-hole array divides the flexible disk into two parts, namely the main disk body on the inner side and the annular edge on the outer side.

[0008] In the above structure, the arrangement of the through-hole array enables the annular edge portion to be more easily deformed, so as to expand the deformable area of the annular edge, such that more areas on the flexible disk can directly or indirectly abut against each other to generate an everted deformation. The area on the flexible disk that generates deformation due to direct or indirect abutment is called the deformation area, and the central angle of both ends of the deformation area relative to the center of the flexible disk can become larger. Moreover, due to the improved deformability of the annular edge, the clamping force at each position of the deformation area can become relatively uniform, and there will be no situation where the clamping force at the central part of the deformation area is significantly greater than that at both ends.

[0009] Furthermore, a spacer ring is fixed to the inner side of the annular edge.

[0010] When actually clamping the sweet potato seedlings, the component directly acting on the sweet potato seedlings is the above-mentioned spacer ring. The clamping surface of the spacer ring is higher than the inner wall of the flexible disk. After clamping the sweet potato seedlings, the part with more upper leaves of the sweet potato seedlings is suspended and will not be affected by the flexible disk. The material of the spacer ring is softer than that of the annular edge, and the spacer ring can play a buffering role to prevent the flexible disk from pinching the sweet potato seedlings.

[0011] Furthermore, during operation, the positions of the lower front sides of the two flexible disks are closest to each other, and the positions of the upper rear sides are farthest from each other. Thus, the deformation area on the flexible disk extends from its foremost point to its lowest point, and the central angle of the deformation area relative to the center of the flexible disk is about 90°. The sweet potato seedlings can enter between the two flexible disks in a flat posture and are clamped by the two flexible disks as they rotate. Until the sweet potato seedlings become vertical, the two flexible disks release the sweet potato seedlings, and the roots of the sweet potato seedlings are placed in the planting groove after release.

[0012] Furthermore, the flexible disk is made of metal, and the spacer ring is made of rubber.

[0013] Furthermore, it also includes a frame body arranged corresponding to each of the flexible disks; the frame body has a first rod portion and a second rod portion which are parallel to each other, and the two rod portions are arranged in an inclined layout with the front higher and the rear lower, and the two rod portions are placed on both sides of the center of the corresponding flexible disk; wherein the first rod portion is located at a lower position and outside the annular edge, and the second rod portion is located at an upper position and inside the annular edge; the two frames corresponding to the two flexible disks can be elastically opened and closed. In the above structure, the first rod portion can determine the exact edge position of the deformation area folded outward on the flexible disk, increase the area of the deformation area, and keep the clamping force on the sweet potato seedlings relatively consistent during the clamping process. Since the two frames can be elastically opened and closed, they can be adapted to the sweet potato seedlings of different thicknesses for adaptive opening and closing adjustment to prevent the sweet potato seedlings from being clamped. The second rod portion is used to open the upper side of the flexible disk so that the sweet potato seedlings can more easily enter between the two flexible disks. This structure is suitable for the case where the flexible disk is made of a thinner material or a softer material, which ensures that the flexible disk has sufficient deformation capacity and sufficient clamping force.

[0014] Furthermore, the frames are respectively connected to the rotating frames, and the two rotating frames corresponding to the two frames are hinged to each other; and a spring is connected between the two frames.

[0015] A transplanting and covering device, comprising two covering wheels arranged in a V-shape; and also comprising the above-mentioned sweet potato seedling transplanting mechanism, wherein the two covering wheels are respectively arranged on the outside of the two flexible disks, that is, at least a part of the flexible disk is located between the two covering wheels. In the above-mentioned structure, when viewed from the side, the projections of the covering wheel and the flexible disk have a large overlapping area, which makes full use of the spatial layout between the two covering wheels in the traditional covering mechanism. The transplanting mechanism composed of two flexible disks makes the flexible disk only need to occupy a small external space, and can accurately move the sweet potato seedlings between the two covering wheels for covering with soil, and release the sweet potato seedlings after the roots of the sweet potato seedlings are covered with soil, so as to ensure that the roots of the sweet potato seedlings are covered with soil after transplanting, and the heads are exposed outside the soil.

[0016] Furthermore, a second bracket is mounted on the first bracket, and the soil covering wheel is mounted on the second bracket; the relative position between the first bracket and the second bracket can be changed, so that the relative height position between the flexible disk and the soil covering wheel can be changed. In this way, the height of the soil covering wheel relative to the flexible disk can be adjusted, that is, the amount of soil covering the roots of the sweet potato seedlings can be adjusted to ensure the planting effect.

[0017] Further, the second bracket is rotatably mounted relative to the first bracket, and the second bracket is provided with an arc-shaped hole. A fixing screw is arranged on the first bracket and passes through the arc-shaped hole. A rotating rod is mounted at the end of the fixing screw. The extending direction of the rotating rod is perpendicular to the extending direction of the fixing screw, and the rotating rod can slide relative to the fixing screw to facilitate the rotation of the fixing screw. A nut cooperating with the fixing screw is fixed on the first bracket. When the angle of the second bracket needs to be adjusted, the rotating rod can be rotated to loosen the fixing screw, and after the adjustment is in place, the rotating rod is rotated again to tighten the fixing screw.

[0018] Further, the lower end of the flexible disk is higher than the lower end of the soil covering wheel. During actual operation, the flexible disk enables the roots of the sweet potato seedlings to enter the planting groove, and the flexible disk does not enter the groove and will not be covered by the soil pushed into the planting groove by the soil covering wheel.

[0019] The above transplanting and soil covering device can be used as a module. It is structurally compact and meets the requirements of sweet potato transplanting. It can be detached from the machine as a whole, which is convenient for maintenance.

[0020] Beneficial effects: In the sweet potato seedling transplanting mechanism and the transplanting and soil covering device of the present invention, the through-hole array on the flexible disk can make the annular edge part easier to deform, so as to expand the deformable area of the annular edge. In this way, the flexible disk can be made of a relatively hard material, and the area of the annular edge that can participate in clamping is larger, and it is ensured that there is a large clamping force on the sweet potato seedlings. In the preferred solution, the boundary of the deformation area on the flexible disk can also be determined by setting a frame and ensuring the consistency of the clamping effect of each position in the deformation area on the flexible disk on the sweet potato seedlings. The transplanting and soil covering device installs the flexible disk between two soil covering wheels, making full use of the space between the two soil covering wheels, so that the whole transplanting and soil covering device meets the requirements of sweet potato transplanting and the structure reaches the most compact state, with very good practicability.

Specific embodiments

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] As Figure 1 shown in the sweet potato seedling transplanting mechanism, it includes a first support 7 and two symmetrically installed flexible disks 1, and the two flexible disks 1 are arranged in a V shape; a through-hole array is formed on the flexible disk 1, and the through-hole array includes a plurality of through holes 1a arranged in a circumferential array; the through-hole array divides the flexible disk 1 into two parts, namely the inner main disk body 11 and the outer annular edge 12.

[0030] In the above structure, on the one hand, the setting of the through-hole array can make the annular edge 12 part easier to deform, so as to expand the deformable area S of the annular edge 12, so that more areas on the flexible disk 1 can directly or indirectly abut against each other to produce outward turning deformation. The area on the flexible disk 1 that deforms due to direct or indirect abutment is called the deformation area S, and the central angle of both ends of the deformation area S relative to the center of the flexible disk 1 can become larger. And due to the improved deformability of the annular edge 12, the clamping force of each position in the deformation area S on the sweet potato seedlings can become relatively consistent, and there will be no situation where the clamping force in the central part of the deformation area S is significantly greater than that in the two end parts. On the other hand, as Figure 2 shown, a gear 10 can be arranged to mesh with the through-hole array to drive the flexible disk 1 to rotate, ensuring reliable transmission, and the flexible disk 1 will not slip, and sweet potato seedlings can be transplanted at equal intervals.

[0031] A spacer ring 2 is fixed to the inner side of the annular edge 12. When actually clamping the sweet potato seedlings, the component directly acting on the sweet potato seedlings is the above-mentioned spacer ring 2. The clamping surface of the spacer ring 2 is higher than the inner wall of the flexible disk 1. After clamping the sweet potato seedlings, the part with more upper leaves of the sweet potato seedlings is suspended and will not be affected by the flexible disk 1. The material of the spacer ring 2 is softer than that of the annular edge 12. For example, the flexible disk 1 can be made of metal, and the spacer ring 2 can be made of rubber. The spacer ring 2 can play a buffering role to prevent the flexible disk 1 from pinching the sweet potato seedlings.

[0032] During operation, the front oblique lower parts of the two flexible disks 1 are closest to each other, and the rear oblique upper parts are farthest apart. In this way, the deformation area S on the flexible disk 1 extends from its frontmost point to the lowest point, and the central angle of the deformation area S relative to the center of the flexible disk 1 is about 90°. The sweet potato seedling can enter between the two flexible disks 1 in a horizontal posture, and is clamped by the two flexible disks 1 and rotates with the flexible disks 1 until the sweet potato seedling becomes a vertical state, and the two flexible disks 1 release the sweet potato seedling, and after release, the root of the sweet potato seedling is placed in the planting groove.

[0033] like Figure 3 As shown, in a preferred embodiment, the sweet potato seedling transplanting mechanism also includes a frame 3 arranged corresponding to each of the flexible disks 1; the frame 3 has a first rod portion 31 and a second rod portion 32 parallel to each other, both of which are arranged with a high front and a low back and inclined, and the two rod portions are placed on both sides of the center of the corresponding flexible disk 1; wherein the first rod portion 31 is located at a lower position on the outside of the annular edge 12, and the second rod portion 32 is located at an upper position and on the inside of the annular edge 12; the two frames 3 corresponding to the two flexible disks 1 can be elastically opened and closed. Specifically, the frame 3 is connected to the rotating frame 4 respectively, and the two rotating frames 4 corresponding to the two frames 3 are hinged to each other; a spring 5 is connected between the two frames 3.

[0034] In the above structure, the first rod portion 31 can determine the exact edge position of the deformation area S that is folded outward on the flexible disk 1, increase the area of the deformation area S, and maintain a relatively consistent clamping force on the sweet potato seedlings during the clamping process. Since the two frames 3 can be elastically opened and closed, they can be adapted to the sweet potato seedlings of different thicknesses for adaptive opening and closing adjustment to prevent the sweet potato seedlings from being damaged by clamping. The second rod portion 32 is used to open the upper side of the flexible disk 1 so that the sweet potato seedlings can more easily enter between the two flexible disks 1. This structure is suitable for the situation where the flexible disk 1 is made of a thinner material or a softer material, which ensures that the flexible disk 1 has sufficient deformation ability and sufficient clamping force.

[0035] The present invention also provides a transplanting and covering soil device, such as Figure 3 , 3As shown in FIGS. 5, it includes two soil covering wheels 6 arranged in a V-shaped layout; it also includes the above-mentioned sweet potato seedling transplanting mechanism. The two soil covering wheels 6 are respectively arranged outside the two flexible discs 2, that is, at least a part of the flexible disc 2 is located between the two soil covering wheels 6. In the above structure, when viewed laterally, the projections of the soil covering wheels 6 and the flexible discs 2 have a large overlapping area. The space layout between the two soil covering wheels 6 in the traditional soil covering mechanism is fully utilized by the seedling transplanting mechanism composed of two flexible discs 2, so that the flexible disc 2 only needs to occupy a very small external space, and can accurately move the sweet potato seedlings between the two soil covering wheels 6 for soil covering, and release the sweet potato seedlings after the roots of the sweet potato seedlings are covered with soil, ensuring that the roots of the transplanted sweet potato seedlings are covered by the soil and the heads are exposed outside the soil.

[0036] A second bracket 8 is also installed on the first bracket 7, and the soil covering wheel 6 is installed on the second bracket 8; the relative position between the first bracket 7 and the second bracket 8 can be changed so that the relative height position of the flexible disc 2 and the soil covering wheel 6 can be changed. In this way, the height of the soil covering wheel 6 relative to the flexible disc 2 can be adjusted, that is, the amount of soil covering the roots of the sweet potato seedlings can be adjusted to ensure the planting effect.

[0037] Preferably, the second bracket 8 is rotatably installed relative to the first bracket 7, and the second bracket 8 has an arc-shaped hole 81. A fixing screw 91 passing through the arc-shaped hole 81 is provided on the first bracket 7. A rotating rod 92 is installed at the end of the fixing screw 91. The extending direction of the rotating rod 92 is perpendicular to the extending direction of the fixing screw 91, and the rotating rod 92 can slide relative to the fixing screw 91 to facilitate rotating the fixing screw 91. A nut cooperating with the fixing screw 91 is fixed on the first bracket 7. When the angle of the second bracket 8 needs to be adjusted, the rotating rod 92 can be rotated to loosen the fixing screw 91, and then the rotating rod 92 can be rotated again to tighten the fixing screw 91 after adjustment.

[0038] Preferably, the lower end of the flexible disc 2 is higher than the lower end of the soil covering wheel 6. During actual operation, the flexible disc 2 makes the roots of the sweet potato seedlings enter the planting groove, and the flexible disc 2 does not enter the groove and will not be covered by the soil in the planting groove pushed by the soil covering wheel 6.

[0039] The above-mentioned transplanting and soil covering device can be used as a module, with a compact and small structure, meeting the requirements of sweet potato transplanting, and can be disassembled as a whole relative to the machine tool, which is convenient for maintenance.

[0040] The above are only the preferred embodiments of the present invention. It should be pointed out that: for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
