Description

Technical Field

[0001] This invention relates to the field of crop seedling transplanting equipment, and more particularly to a seedling placement device for a transplanter. Background Technology

[0002] With the development of well-type transplanting techniques, transplanting machines have gradually replaced manual labor. This involves using a conical wooden stick to drill a hole 5 to 10 centimeters in diameter and 12 to 20 centimeters deep in the ridge, and then placing the crop seedling into the hole. See patent application CN201510553467.3, which discloses "A method and device for placing seedlings with a transplanting machine." In this method, the crop seedling is manually inserted into the hole in the ridge through an inner tube. Because it is necessary to ensure that only one seedling is placed in each hole, the operator of the transplanting machine needs to concentrate highly on placing the seedling; otherwise, too many or too few seedlings may be placed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a seedling placement device for a transplanter, which can be combined with a watering device, a fertilization mechanism and a well-hole drilling mechanism to achieve multi-functional transplanting operations, reduce the difficulty of operation for operators, and avoid the occurrence of over-placement or under-placement of crop seedlings, thereby improving agricultural production efficiency and operation quality.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a seedling distribution device for a transplanter, comprising a feeding component, a seedling tray rotatably disposed on the transplanter, and a reciprocating support movably disposed inside the transplanter;

[0005] The feeding assembly includes a seedling funnel and a baffle; the seedling funnel is connected to a reciprocating support; the baffle is mounted on the frame of the transplanter.

[0006] The seedling tray is provided with multiple seedling cups, and the discharge end of the seedling tray is provided with a partition, the partition is provided with a through hole, and the partition is connected to the seedling funnel.

[0007] The reciprocating support moves in a horizontal direction;

[0008] When the feed end of the seedling funnel is below the discharge end of the seedling tray, the through hole is connected to the seedling cup, and the baffle blocks the discharge end of the seedling funnel.

[0009] When the feed end of the seedling funnel is far from the discharge end of the seedling tray, the partition intercepts the discharge end of the seedling tray, and the discharge end of the seedling funnel is far from the baffle.

[0010] The beneficial effect of the present invention is that a seedling tray with multiple seedling cups is added to the transplanter, so that multiple seedlings can be placed one seedling per seedling cup to fill the entire seedling tray. Because the seedling funnel is connected to the reciprocating support, the seedling funnel and the reciprocating support move back and forth horizontally during the operation of the transplanter. When the feed end of the seedling funnel is below the discharge end of the seedling tray, the seedlings in the seedling cups at the discharge end of the seedling tray will fall into the seedling funnel through the through hole of the partition and be intercepted by the baffle at the discharge end of the seedling funnel. When the feed end of the seedling funnel is away from the discharge end of the seedling tray, the through hole of the partition is no longer connected to the seedling cups at the discharge end of the seedling tray. At this time, the seedling tray rotates, which can rotate the other seedling cups containing seedlings to the discharge end of the seedling tray. At this time, the discharge end of the seedling funnel is away from the baffle, and the seedlings at the discharge end of the seedling funnel can fall out of the discharge end of the seedling funnel and fall into the holes that the hole-drilling cone of the transplanter has just drilled on the ridge. Throughout the seedling placement process, it is only necessary to ensure that there are crop seedlings in the next seedling cup that will be transferred to the seedling tray. The operator on the transplanter can replenish the seedling cup with crop seedlings at any time, thereby reducing the difficulty of the operator's work. Attached Figure Description

[0021] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please refer to Figure 1 and Figure 2 As shown, the present invention provides a seedling distribution device for a transplanter, comprising a feeding assembly 1, a seedling tray 2 rotatably mounted on the transplanter, and a reciprocating support 3 movably mounted inside the transplanter;

[0023] The feeding assembly 1 includes a seedling funnel 11 and a baffle 12. The seedling funnel 11 is connected to the reciprocating support 3. The baffle 12 is mounted on the frame of the transplanter.

[0024] The seedling tray 2 is provided with a plurality of seedling cups 21, and the discharge end of the seedling tray 2 is provided with a partition 22, the partition 22 is provided with a through hole 221, and the partition 22 is connected to the seedling funnel 11.

[0025] The reciprocating support 3 moves in a horizontal direction;

[0026] When the feed end of the seedling funnel 11 is below the discharge end of the seedling tray 2, the through hole 221 is connected to the seedling cup 21, and the baffle 12 intercepts the discharge end of the seedling funnel 11.

[0027] When the feed end of the seedling funnel 11 is far away from the discharge end of the seedling tray 2, the partition 22 intercepts the discharge end of the seedling tray 2, and the discharge end of the seedling funnel 11 is far away from the baffle 12.

[0028] As can be seen from the above description, the beneficial effects of the present invention are as follows: A seedling tray 2 with multiple seedling cups 21 is added to the transplanter, allowing multiple seedlings to be placed in one seedling cup 21 to fill the entire seedling tray 2. Since the seedling funnel 11 is connected to the reciprocating support 3, during operation, the seedling funnel 11 and the reciprocating support 3 reciprocate horizontally. When the feed end of the seedling funnel 11 is below the discharge end of the seedling tray 2, the seedlings in the seedling cups 21 at the discharge end of the seedling tray 2 will pass through the through-hole 221 of the partition 22 and fall into the seedling funnel 11, where they are intercepted by the baffle 12 at the discharge end of the seedling funnel 11. When the feed end of the seedling funnel 11 is below the discharge end of the seedling tray 2, the seedlings in the seedling cups 21 at the discharge end of the seedling tray 2 will pass through the through-hole 221 of the partition 22 and fall into the seedling funnel 11, where they are intercepted by the baffle 12 at the discharge end of the seedling funnel 11. When the feed end is far from the discharge end of the seedling tray 2, the through hole 221 of the partition 22 is no longer connected to the seedling cup 21 located at the discharge end of the seedling tray 2. At this time, the seedling tray 2 rotates, which can rotate another seedling cup 21 containing seedlings to the discharge end of the seedling tray 2. At this time, the discharge end of the seedling funnel 11 is far from the baffle 12, so the seedlings located at the discharge end of the seedling funnel 11 can fall out from the discharge end of the seedling funnel 11 and fall into the hole that the hole-drilling cone of the transplanter has just drilled on the ridge. During the entire seedling process, it is only necessary to ensure that the next seedling cup 21 that is about to be rotated to the discharge end of the seedling tray 2 contains crop seedlings. The operator on the transplanter can replenish crop seedlings into the seedling cup 21 at any time, thereby reducing the difficulty of the operator's work.

[0029] Please refer to Figure 1 As shown, the partition 22 further includes a return spring 222, a partition 223, and an abutment plate 224; one end of the return spring 222 is connected to the frame of the transplanter, and the other end of the return spring 222 is connected to the partition 223. The through hole 221 is provided on the partition 223, and the abutment plate 224 is provided on the end face of the partition 223 away from the seedling tray 2. The abutment plate 224 abuts against the outer wall of the seedling funnel 11.

[0030] As described above, when the reciprocating support 3 moves the seedling funnel 11 to below the discharge end of the seedling tray 2, the partition 223 will also move as the seedling funnel 11 moves, so that the through hole 221 gradually approaches the discharge end of the seedling tray 2 and stretches the return spring 222.

[0031] As the reciprocating support 3 moves the seedling funnel 11 away from the discharge end of the seedling tray 2, the partition 223, under the elastic force of the return spring 222, causes the through hole 221 to gradually move away from the discharge end of the seedling tray 2.

[0032] Please refer to Figure 1As shown, the seedling placement device of the transplanter further includes a water outlet component 4; the water outlet component 4 includes a water outlet chamber 41 and a water tank 42; the water outlet chamber 41 is connected to the water tank 42 by a pipe, the water outlet chamber 41 has a water outlet end with a diameter larger than the diameter of the discharge end of the seedling funnel 11, and the discharge end of the seedling funnel 11 passes through the water outlet chamber 41 and extends out from the water outlet end.

[0033] As described above, during the seedling placement process, the water in the water tank 42 forms a ring of water by cooperating with the outlet chamber 41 and the discharge end of the seedling funnel 11. This allows the soil around the seedling to fill the gap between the hole and the seedling under the washing of the ring of water after the seedling falls into the hole, thus ensuring the survival rate of the seedling.

[0034] Furthermore, the water outlet is a tube whose diameter gradually decreases toward the discharge end of the seedling funnel 11.

[0035] As described above, the outlet end of the water outlet chamber 41 is a pipe with a gradually decreasing diameter, which can increase the water pressure and flow rate of the water flowing out of the water outlet chamber 41, thereby ensuring that the outflowing water is in a ring shape.

[0036] Please refer to Figure 1 and Figure 3 As shown, the seedling placement device of the transplanter further includes a control component 5; the control component 5 includes a valve body 51 and a movable block 52 slidably disposed in the inner cavity of the valve body 51. The valve body 51 includes a first port 511, a second port 512 and a clearance chamber 513 that are interconnected. The first port 511 is connected to a water tank 42, the second port 512 is connected to a water outlet chamber 41, and the clearance chamber 513 has space for the movable block 52 to enter.

[0037] When the discharge end of the cloth seedling funnel 11 moves away from the baffle 12, the movable block 52 intercepts the connection between the first port 511 and the second port 512.

[0038] When the baffle 12 intercepts the material at the discharge end of the cloth funnel 11, the movable block 52 enters the clearance chamber 513, and the first port 511 and the second port 512 are connected.

[0039] As described above, the movable block 52 moves within the valve body 51 to control the connection between the first port 511 and the second port 512, thereby controlling the water output from the water outlet chamber 41.

[0040] Please refer to Figure 3 As shown, the control component 5 further includes a linkage rod 53, which passes through the valve body 51 and is slidably connected to the valve body 51. The movable block 52 is disposed on the linkage rod 53.

[0041] The transplanter has a first abutting member 6 and a second abutting member 7 on its frame;

[0042] When one end of the linkage rod 53 abuts against the first abutting member 6, the movable block 52 intercepts the connection between the first port 511 and the second port 512.

[0043] When the other end of the linkage 53 abuts against the second abutting member 7, the movable block 52 enters the clearance chamber 513.

[0044] As can be seen from the above description, the movement of the movable block 52 within the valve body 51 is achieved by the contact between the first abutting member 6 and the second abutting member 7 and the corresponding ends of the linkage rod 53.

[0045] Please refer to Figure 1 As shown, the water outlet assembly 4 further includes a control valve 43, which is used to control the flow rate of water in the pipeline connecting the water outlet chamber 41 and the water tank 42.

[0046] As can be seen from the above description, the water output of the water tank 42 can be adjusted appropriately according to actual needs using the control valve 43.

[0047] Furthermore, the diameter of the feed end of the seedling funnel 11 gradually increases toward the seedling tray 2.

[0048] As described above, it is important to ensure that the seedlings can effectively fall into the seedling funnel 11.

[0049] The application scenario of the seedling placement device of the transplanter of the present invention is as follows: When it is necessary to transplant crop seedlings, a seedling tray 2 with multiple seedling cups 21 is added to the transplanter, so that multiple seedlings can be placed one seedling per seedling cup 21 to fill the entire seedling tray 2. Since the seedling placement funnel 11 is connected to the reciprocating support 3, the seedling placement funnel 11 will reciprocate in the horizontal direction with the reciprocating support 3 during the operation of the transplanter. When the feeding end of the seedling placement funnel 11 is below the discharging end of the seedling tray 2, the seedlings in the seedling cups 21 at the discharging end of the seedling tray 2 will fall into the seedling placement funnel 11 through the through hole 221 of the partition 22 and be intercepted by the baffle 12 at the discharging end of the seedling placement funnel 11; when .... When the feed end is far from the discharge end of the seedling tray 2, the through hole 221 of the partition 22 is no longer connected to the seedling cup 21 located at the discharge end of the seedling tray 2. At this time, the seedling tray 2 rotates, which can rotate another seedling cup 21 containing seedlings to the discharge end of the seedling tray 2. At this time, the discharge end of the seedling funnel 11 is far from the baffle 12, so the seedlings located at the discharge end of the seedling funnel 11 can fall out from the discharge end of the seedling funnel 11 and fall into the hole that the hole-drilling cone of the transplanter has just drilled on the ridge. During the entire seedling process, it is only necessary to ensure that the next seedling cup 21 that is about to be rotated to the discharge end of the seedling tray 2 contains crop seedlings. The operator on the transplanter can replenish crop seedlings into the seedling cup 21 at any time, thereby reducing the difficulty of the operator's work.

[0050] Example 1

[0051] A seedling distribution device for a transplanter, please refer to Figure 1 and Figure 2 As shown, the transplanter includes a feeding assembly 1, a seedling tray 2 rotatably mounted on the transplanter, and a reciprocating support 3 movably mounted inside the transplanter. The feeding assembly 1 includes a seedling funnel 11 and a baffle 12, with the seedling funnel 11 connected to the reciprocating support 3. The baffle 12 is mounted on the frame of the transplanter. The seedling tray 2 has multiple seedling cups 21, and the discharge end of the seedling tray 2 has a partition 22 with through holes 221. The partition 22 is connected to the seedling funnel 11; the reciprocating support 3 moves in a horizontal direction; when the feed end of the seedling funnel 11 is below the discharge end of the seedling tray 2, the through hole 221 is connected to the seedling cup 21, and the baffle 12 intercepts the discharge end of the seedling funnel 11; when the feed end of the seedling funnel 11 is far away from the discharge end of the seedling tray 2, the partition 22 intercepts the discharge end of the seedling tray 2, and the discharge end of the seedling funnel 11 is far away from the baffle 12.

[0052] Please refer to Figure 1As shown, the partition 22 includes a return spring 222, a partition plate 223, and an abutment plate 224. One end of the return spring 222 is connected to the frame of the transplanter, and the other end is connected to the partition plate 223. The through hole 221 is provided on the partition plate 223, and the abutment plate 224 is provided on the end face of the partition plate 223 away from the seedling tray 2. The abutment plate 224 abuts against the outer wall of the seedling funnel 11. The diameter of the feed end of the seedling funnel 11 gradually increases towards the seedling tray 2.

[0053] Working principle: During the seedling placement process, the seedling funnel 11 will reciprocate in the horizontal direction together with the reciprocating support 3. When the reciprocating support 3 drives the seedling funnel 11 to move below the discharge end of the seedling tray 2, since the abutment plate 224 abuts against the outer wall of the seedling funnel 11, the partition plate 223 will also move along with the seedling funnel 11 during the movement, so that the through hole 221 gradually approaches the discharge end of the seedling tray 2 and stretches the return spring 222. When the through hole 221 is connected to the seedling cup 21 located at the discharge end of the seedling tray 2, the crop seedling in the seedling cup will fall through the through hole 221 into the seedling funnel 11 and be intercepted by the baffle 12 at the discharge end of the seedling funnel 11. When the reciprocating support 3 drives the seedling funnel 11 to move away from the discharge end of the seedling tray 2, the baffle 223, under the elastic force of the return spring 222, makes the through hole 221 gradually move away from the discharge end of the seedling tray 2. When the through hole 221 is no longer connected to the seedling cup 21 located at the discharge end of the seedling tray 2, the seedling tray 2 rotates, turning the other seedling cup 21 containing seedlings to the discharge end of the seedling tray 2. At this time, the discharge end of the seedling funnel 11 moves away from the baffle 12, and the seedlings located at the discharge end of the seedling funnel 11 can fall out from the discharge end of the seedling funnel 11 and fall into the hole that the hole-drilling cone of the transplanter has just drilled on the ridge.

[0054] Example 2

[0055] This embodiment further specifies, based on Embodiment 1, that the seedling distribution device of the transplanter also includes a water outlet component:

[0056] Please refer to Figure 1 and Figure 3 As shown, the water outlet assembly 4 includes a water outlet chamber 41 and a water tank 42; the water outlet chamber 41 is connected to the water tank 42 by a pipe, and the water outlet chamber 41 has a water outlet end with a diameter larger than the diameter of the discharge end of the seedling funnel 11. The discharge end of the seedling funnel 11 passes through the water outlet chamber 41 and extends out from the water outlet end. The water outlet end is a pipe whose diameter gradually decreases towards the discharge end of the seedling funnel 11.

[0057] Please refer to Figure 1 and Figure 3As shown, the seedling placement device of the transplanter also includes a control component 5; the control component 5 includes a valve body 51 and a movable block 52 slidably disposed in the inner cavity of the valve body 51. The valve body 51 includes a first port 511, a second port 512, and a clearance chamber 513 that are interconnected. The first port 511 is connected to a water tank 42, and the second port 512 is connected to a water outlet chamber 41. The clearance chamber 513 has space for the movable block 52 to enter. When the discharge end of the seedling funnel 11 is far away from the baffle 12, the movable block 52 intercepts the connection between the first port 511 and the second port 512. When the baffle 12 intercepts the discharge end of the seedling funnel 11, the movable block 52 enters the clearance chamber 513, and the first port 511 and the second port 512 are connected. The control component 5 further includes a linkage rod 53, which passes through the valve body 51 and is slidably connected to the valve body 51. A movable block 52 is disposed on the linkage rod 53. The transplanter frame has a first abutment 6 and a second abutment 7 facing each other. When one end of the linkage rod 53 abuts against the first abutment 6, the movable block 52 blocks the connection between the first port 511 and the second port 512. When the other end of the linkage rod 53 abuts against the second abutment 7, the movable block 52 enters the clearance chamber 513. The water outlet component 4 further includes a control valve 43, which controls the flow rate of water in the pipeline connecting the water outlet chamber 41 and the water tank 42.

[0058] Working principle: When the crop seedlings fall into the discharge end of the seedling funnel 11 and are intercepted by the baffle 12, the linkage rod 53 of the control component 5 abuts against the second abutting member 7, causing the linkage rod 53 to move, that is, the movable block 52 enters the clearance chamber 513 of the valve body 51, so that the first port 511 and the second port 512 are connected, and the water in the water tank 42 can flow into the water outlet chamber 41.

[0059] After a measured amount of water flows into the outlet chamber 41, the reciprocating support 3 moves the seedling funnel 11 away from the baffle 12, causing the linkage rod 53 to move towards the first abutment 6, making contact with the first abutment 6. This causes the linkage rod 53 to move, meaning the movable block 52 intercepts the connection between the first port 511 and the second port 512, preventing water from flowing into the outlet chamber 41. Simultaneously, the water in the outlet chamber 41, along with the crop seedlings at the discharge end of the seedling funnel, falls towards the holes drilled on the soil ridge. Since the discharge end of the seedling funnel 11 extends beyond the water outlet end of the outlet chamber 41, and the diameter of the water outlet end of the outlet chamber 41 is larger than the diameter of the discharge end of the seedling funnel 11, the water flowing out of the water outlet end of the outlet chamber 41 forms a ring. This ensures that after the seedlings fall into the holes, the soil around the seedlings is washed away by the ring-shaped water, filling the gap between the holes and the seedlings, thus guaranteeing the survival rate of the seedlings.

[0060] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
