Description

Technical Field

[0001] The invention relates to the technical field of planting, in particular to a seedling transplanting device for planting traditional Chinese medicine. Background Art

[0002] Chinese medicinal materials refer to native medicinal materials used under the guidance of traditional Han medicine to treat diseases. Generally, traditional Chinese medicinal materials pay attention to authentic medicinal materials, which refer to medicinal materials produced in a region with specific natural conditions and ecological environment. Because the production is relatively concentrated, the cultivation technology, harvesting and processing are also certain, so that the quality and efficacy are better than the same medicinal materials produced in other regions. The planting of Chinese medicinal materials is divided into direct seeding, transplanting and grafting. In order to shorten the growth time, improve the survival rate and increase the yield, many Chinese medicinal materials are usually transplanted.

[0003] A search of Chinese utility model patent publication number CN220369029U discloses a seedling transplanting device for planting Chinese medicinal materials. In this technical solution, workers store the seedlings of Chinese medicinal materials in a storage box. When transplanting and planting, the workers take out the seedlings in the storage box and put the seedlings into a cylindrical tube (referred to as a seedling throwing tube in this application) with their roots facing downward. Then, a plurality of conical pieces (referred to as claws in this application) are unfolded to allow the seedlings to fall into holes (referred to as planting pits in this application) formed by squeezing the conical pieces.

[0004] Although the above technical scheme solves the problem of how to transplant the seedlings on the surface, since there is no soil covering the hole after the pit is formed, the seedlings are not covered with soil after transplanting. Workers need to fill the soil later to cover the root and stem of the seedlings with soil. Obviously, this method will make the transplanting efficiency low, and the workers often fill the soil manually, which makes the physical labor intensity high and is not suitable for promotion and use. Summary of the invention

[0005] The purpose of the present invention is to provide a seedling transplanting device for Chinese medicinal materials planting to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A seedling transplanting device for Chinese medicinal materials planting comprises a mobile vehicle body and also comprises:

[0008] A lifting unit is provided on the mobile vehicle frame, wherein the output end of the lifting unit is connected to a lifting plate, and a plurality of through holes are provided on the surface of the lifting plate, and the plurality of through holes are arranged in a row;

[0009] A seedling throwing tube fixedly installed in the perforation, wherein the seedling throwing tube is provided with a seedling throwing unit;

[0010] A floating plate is slidably sleeved on the periphery of the seedling casting tube, and a plurality of backfilling units are arranged at one end of the floating plate away from the seedling casting tube, and the positions and quantities of the backfilling units correspond to the positions and quantities of the seedling casting tube.

[0011] Through the above technical scheme, after the lifting unit drives the lifting plate to move downward, the seedling throwing unit moves downward and forms a planting pit on the ground surface. The seedlings of Chinese medicinal materials will fall into the planting pit by the seedling throwing unit, and then the seedlings will be transplanted. After transplanting, the backfilling unit drives the soil at the edge of the planting pit into the planting pit, and then covers the seedlings with soil. There is no need for the staff to backfill the planting pit with planting soil afterwards, which improves the efficiency of transplanting seedlings and is suitable for promotion and use.

[0012] Furthermore, a seedling storage bin is provided on the upper side of the mobile vehicle body, and the lifting plate is located below the seedling storage bin.

[0013] Through the above technical scheme, the Chinese medicinal material seedlings to be transplanted are stored in the seedling storage bin, so that when the mobile vehicle is moving, workers can take the Chinese medicinal material seedlings in the seedling storage bin and put the Chinese medicinal material seedlings into the seedling throwing tube.

[0014] Furthermore, a plurality of delivery tubes are fixedly connected to the outer side wall of the seedling storage bin, the delivery tubes are located directly above the seedling delivery tube, and the delivery tubes are coaxial with the seedling delivery tube.

[0015] Through the above technical solution, after the seedlings in the seedling storage bin are taken out, they are placed in the delivery tube, and the seedlings fall into the seedling delivery tube along the delivery tube, and the staff does not need to bend down to place the seedlings into the seedling delivery tube.

[0016] Furthermore, a guide portion is provided at the upper end portion of the seedling throwing tube, and the outer diameter of the guide portion decreases from bottom to top.

[0017] Through the technical solution, the seedlings of Chinese medicinal materials can be accurately dropped into the seedling dropping tube under the guidance of the guide part.

[0018] Furthermore, the lifting unit includes at least one first cylinder vertically mounted on the mobile body, and a cylinder rod of the first cylinder is connected to the lifting plate.

[0019] Through the above technical solution, the cylinder rod of the first cylinder is extended and retracted, thereby driving the lifting plate to move vertically up and down.

[0020] Furthermore, the seedling throwing unit includes a fixing ring fixedly connected to the bottom surface of the floating plate, the fixing ring is sleeved on the periphery of the seedling throwing tube and can slide vertically and freely on the periphery of the seedling throwing tube, two claws are hinged on the lower end of the seedling throwing tube, a swing arm is fixedly connected to the upper outer wall of the claw, a hinge rod is hinged on the end of the swing arm, and one end of the hinge rod away from the swing arm is correspondingly hinged to the periphery of the fixing ring, a second cylinder is vertically installed on the top of the lifting plate, and the cylinder rod of the second cylinder penetrates the lifting plate and is connected to the floating plate.

[0021] Through the above technical scheme, when the cylinder rod of the second cylinder is shortened, the floating plate is driven to move upward, and then the floating plate moves relative to the lifting plate, so that the fixed ring slides upward on the periphery of the seedling throwing tube, and then the hinge rod drives the pusher claw to swing upward, so that the pusher claw can expand with each other, and then the seedlings in the seedling throwing tube can fall from the lower end of the seedling throwing tube.

[0022] Furthermore, after the pusher claws rotate along the hinge axis with the seedling throwing tube to a combined state, the maximum outer diameter of the two pusher claws is consistent with the outer diameter of the seedling throwing tube.

[0023] By adopting the above technical scheme, when the claw is inserted into the soil on the surface of the ground, even if the claw is inserted into the soil to a great depth, causing the seedling-dropping tube to be inserted into the soil as well, no great resistance will be generated.

[0024] Furthermore, the backfilling unit includes a lower extension plate fixedly connected to an end of the floating plate away from the seedling planting tube, and the side walls of the lower extension plate are horizontally slidably connected to multiple groups of sliding blocks, each group of sliding blocks has two sliding blocks, and the lower surface of the sliding block is vertically fixed with a fixing rod, and the lower end of the fixing rod is pivotally connected to a backfilling shovel plate, and the upper surface of the backfilling shovel plate is fixed with a limiting stop block, and the limiting stop block is abuttingly connected to one side of the periphery of the fixing rod, and the sliding block is provided with a driving assembly, and the driving assembly is used to drive the two sliding blocks in each group to move relatively close to each other when the floating plate moves downward.

[0025] Through the above technical solution, when the claw is inserted into the soil, the driving assembly will drive the two sliders in each group to move relatively close to each other, so that the backfill shovel plate drives the soil at the edge of the planting pit into the planting pit.

[0026] Furthermore, the driving assembly includes a folding plate fixedly connected to the end of the lifting plate away from the seedling tube, the folding plate extends vertically downward, a sliding pin is fixedly connected to the outer wall of the sliding block, a sliding groove for the sliding pin to be inserted into the surface of the folding plate, and the sliding groove includes a straight groove and an oblique groove from bottom to top, the oblique groove and the straight groove are connected end to end, and the sliding pin slides freely in the straight groove and the oblique groove.

[0027] Through the above technical solution, after the claw is inserted into the ground surface, the second cylinder drives the floating plate to move upward, so that the sliding pin slides from the straight groove to the inclined groove, and then drives the two sliding blocks of the same group to move relatively close, so that the backfill shovel plate can backfill the soil at the edge of the planting pit into the planting pit.

[0028] Furthermore, a connecting column is fixedly connected to the top of the backfill shovel plate, and the connecting column is fixedly connected to the periphery of the pivot. A clearance groove is opened on the periphery of the fixed rod for the connecting column to rotate freely through. A fixing sleeve is fixedly connected to the inner side wall of the clearance groove. The fixing sleeve is coaxial with the pivot. A volute spring is installed in the annular hole of the fixing sleeve. The volute spring sleeve is wrapped around the periphery of the pivot, and the two ends of the volute spring are respectively fixedly connected to the inner wall of the fixing sleeve and the periphery of the pivot.

[0029] Through the above technical solution, when the claw moves downward, the backfill shovel board is also inserted into the soil on the surface. As the sliders move relatively close to each other, the backfill shovel boards approach each other, and then the soil at the edge of the planting pit is backfilled into the planting pit. When the floating plate moves downward, the sliding blocks will move away from each other. At this time, the backfill shovel boards can rotate around the pivot, so that when two adjacent backfill shovel boards are relatively far away, the soil at the edge of the planting pit will not be driven away from the planting pit by the backfill shovel boards.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. After the lifting plate is driven downward by the lifting unit, the seedling throwing unit moves downward to form a planting pit on the ground surface. The seedlings of Chinese medicinal materials are dropped into the planting pit by the seedling throwing unit, and then the seedlings are transplanted. After transplanting, the backfilling unit drives the soil at the edge of the planting pit into the planting pit, and then the seedlings are covered with soil. There is no need for the staff to backfill the planting pit with planting soil later, which improves the efficiency of transplanting seedlings and is suitable for popularization and use;

[0032] 2. When the cylinder rod of the second cylinder of the present invention is shortened, the floating plate is driven to move upward, thereby causing the floating plate to move relative to the lifting plate, causing the fixing ring to slide upward on the periphery of the seedling throwing tube, thereby causing the hinge rod to drive the claws to swing upward, so that the claws can be spread apart, thereby causing the seedlings in the seedling throwing tube to fall from the lower end of the seedling throwing tube;

[0033] 3. The present invention sets a limit block, a spiral spring and a backfill shovel plate. When the claw moves downward, the backfill shovel plate is also inserted into the soil on the surface of the ground. As the sliders move relatively close to each other, the backfill shovel plates approach each other, and then the soil at the edge of the planting pit is backfilled into the planting pit. When the floating plate moves downward, the sliding blocks will move away from each other. At this time, the backfill shovel plates can rotate around the pivot, so that when two adjacent backfill shovel plates are relatively far away, the soil at the edge of the planting pit will not be driven away from the planting pit by the backfill shovel plates.

The cylinder rods of the second cylinders 12 penetrate the lifting plate 5 and are commonly connected to the floating plate 7. When the cylinder rods of the second cylinders 12 are extended and retracted, the floating plate 7 will be synchronously driven to move vertically. The floating plate 7 is sleeved on the periphery of the seedling-throwing tube 9 and slides freely on the periphery of the seedling-throwing tube 9. The seedling-throwing tube 9 is provided with a seedling-throwing unit, which includes a fixing ring 17 fixed to the bottom surface of the floating plate 7. The fixing ring 17 is sleeved on the periphery of the seedling-throwing tube 9 and slides freely vertically on the periphery of the seedling-throwing tube 9. The lower end of the seedling-throwing tube 9 is hinged with Two pusher claws 10, the upper outer wall of the pusher claws 10 is fixedly connected with a swing arm 18, the end of the swing arm 18 is hinged with a hinge rod 14, and the end of the hinge rod 14 away from the swing arm 18 is correspondingly hinged to the periphery of the fixing ring 17. After the pusher claws 10 rotate along the hinge axis with the seedling throwing tube 9 to a merged state, the maximum outer diameter of the two pusher claws 10 is consistent with the outer diameter of the seedling throwing tube 9, and the second cylinder 12 drives the floating plate 7 to move upward, so that the floating plate 7 slides on the periphery of the seedling throwing tube 9, and then drives the fixing ring 17 to move upward synchronously, so that the hinge rod 14 drives the pusher claws 10 to swing upward;

[0048] A plurality of backfilling units are provided at one end of the floating plate 7 away from the seedling-casting tube 9, and the positions and numbers of the backfilling units correspond to the positions and numbers of the seedling-casting tube 9. The backfilling units include a lower extension plate which is arranged at one end of the floating plate 7 away from the seedling-casting tube 9 and is bent downward. A slide rail is horizontally installed on the side wall of the lower extension plate, and sliding blocks are mounted on the slide rail in groups of two. A slider 19 is fixedly connected to each sliding block, so that the slider 19 is horizontally slidably connected to the side wall of the lower extension plate. In addition, the sliders 19 correspond to the number of sliding blocks, that is, there are two sliders in each group of sliders 19. A fixing rod 13 is vertically fixed to the lower surface of the slider 19, and a pivot 22 is horizontally rotatably connected to the lower end of the fixing rod 13. A connecting column 25 is fixedly connected to the periphery of the pivot 22, and a backfilling shovel plate 8 is fixedly connected to the end of the connecting column 25.

When the sliding pin 20 slides from the straight groove 15 to the inclined groove 16, the sliding pin 20 will drive the slider 19 to be relatively close, thereby making the two backfill shovel plates 8 relatively close;

[0049] Combination Figure 8 , Fig. 9 and Fig.10 As shown, a fixing sleeve 24 is fixedly connected to the inner wall of the air avoidance groove, and the fixing sleeve 24 is coaxial with the pivot 22. A volute spring 23 is installed in the annular hole of the fixing sleeve 24. The volute spring 23 is wrapped around the periphery of the pivot 22, and the two ends of the volute spring 23 are respectively fixed to the inner wall of the fixing sleeve 24 and the periphery of the pivot 22. When the pivot 22 drives the backfilling shovel 8 to rotate around the axial direction of the pivot 22 itself toward the direction of another backfilling shovel 8 adjacent to it, the volute spring 23 will be contracted by the pivot 22 and accumulate elastic potential energy.

[0050] Working principle of the present invention:

[0051] The worker starts the mobile body 1, and the mobile body 1 moves linearly on the surface of the planting area. The worker puts the Chinese medicinal material seedlings in the seedling storage bin 3 into the delivery tube 2 with the roots facing downward. At this time, the cylinder rod of the first cylinder 4 is shortened, so that the lower end of the delivery tube 2 extends into the guide part 6 of the seedling delivery tube 9, so that the seedlings fall from the delivery tube 2 into the seedling delivery tube 9, and finally fall into the inner cavity of the two claws 10;

[0052] The first cylinder 4 is started, and its cylinder rod is extended, driving the lifting plate 5 to move downward, thereby causing the lifting plate 5 and the floating plate 7 to move downward synchronously, until the claw 10 is inserted into the surface soil to a fixed depth, and at this time, the backfill shovel plate 8 is inserted into the surface soil in a vertical state, and the two backfill shovel plates 8 in each group are in a state of being away from each other;

[0053] The second cylinder 12 is started, the cylinder rod of the second cylinder 12 is shortened, and the floating plate 7 is driven to slide upward on the periphery of the seedling tube 9, so that the hinge rod 14 drives the swing arm 18 to swing upward, so that the claw 10 is in an unfolded state. When the claw 10 is unfolded, a planting pit can be formed on the ground surface, and the seedling falls into the planting pit from the lower side of the open claw 10. At the same time, since the floating plate 7 moves upward relative to the lifting plate 5, the sliding pin 20 slides from the straight groove 15 to the inclined groove 16, thereby driving the two sliders 19 of each group to move relative to each other. The two backfilling shovels 8 of each group move close to each other, and the limit stopper 21 can limit the rotation stroke of the backfilling shovels 8 around the pivot 22, that is, when the two adjacent backfilling shovels 8 in each group rotate to a vertical state, the backfilling shovels 8 will not be able to continue to rotate in a direction away from each other, so that when the backfilling shovels 8 move toward the previous planting pit, the backfilling shovels 8 drive the soil on the surface at the edge of the previous planting pit into the previous planting pit, so that the seedlings transplanted previously can be covered by the soil;

[0054] Then the cylinder rod of the second cylinder 12 is extended to a certain length, so that the expansion amplitude of the pusher claw 10 is reduced (it should be noted that at this time, the two pusher claws 10 of each group are still in the expanded state, but the expansion amplitude is reduced). In this way, the pusher claw 10 can be taken out of the planting pit without damaging the soil at the inner edge of the planting pit. Since the pusher claw 10 is still in the expanded state, the pusher claw 10 will not damage the seedling when the seedling tube 9 moves upward. At this time, the floating plate 7 will move downward relative to the lifting plate 5, so that the sliding pin 20 moves in the inclined groove 16 toward the direction of the straight groove 15, and the two adjacent The backfill shovel plates 8 are in a state of moving away from each other. At this time, the bottoms of the backfill shovel plates 8 are in contact with the ground surface. Therefore, when the two backfill shovel plates 8 in each group move away from each other, the backfill shovel plates 8 are subjected to resistance from the surface soil at the bottom, thereby causing the two adjacent backfill shovel plates 8 to rotate around the axial direction of the pivot 22 toward each other. During the rotation, the volute spring 23 is contracted, thereby causing the volute spring 23 to accumulate elastic potential energy. In this way, the backfill shovel plates 8 can swing toward the other backfill shovel plates 8 to avoid driving the soil near the edge of the planting pit away from the planting pit.

[0055] The cylinder rod of the first cylinder 4 is shortened and drives the lifting plate 5 to move upward, so that the claw 10 is completely out of the planting pit. The cylinder rod of the second cylinder 12 continues to extend, so that the floating plate 7 moves downward, and the two adjacent claws 10 are brought together. At the same time, when the floating plate 7 moves downward, the sliding pin 20 will slide from the inclined groove 16 to the straight groove 15, so that the two adjacent backfilling shovel plates 8 are separated from each other. In addition, the elastic potential energy accumulated in the spiral spring 23 is released, so that the pivot 22 can be driven to rotate in the opposite direction, so that the backfilling shovel plate 8 rotates, and is limited by the limit block 21 on the outer wall of the fixed rod 13, so that the backfilling shovel plate 8 rotates to a vertical state, that is, returns to the initial state, and then the moving vehicle body 1 is moved, and the worker continues to move. Continue to put the seedlings into the delivery tube 2, and finally repeat the above process, so that the claw 10 transplants the seedlings, and at the same time the backfill shovel 8 covers the seedlings in the previous planting pit with soil. There is no need for the staff to subsequently backfill the soil, which reduces labor intensity and improves the efficiency of transplanting seedlings. Since the spacing between the backfill shovel 8 and the seedling delivery tube 9 in this embodiment is exactly the spacing between two adjacent rows of planting pits, the last row of planting pits can be manually filled by workers. Although it needs to be done manually, the physical labor intensity required can be ignored. Compared with the prior art, all planting pits are completely filled manually, which still achieves the effect of reducing the labor intensity of workers and improving the efficiency of transplanting seedlings achieved by this embodiment.
