Description

Technical Field

[0001] This utility model relates to the field of wheat planting technology, and more specifically, to a portable hole-sowing tool for wheat breeding. Background Technology

[0002] Wheat sowing is a very important part of breeding work. At present, the level of agricultural breeding mechanization in China is relatively low. Most wheat sowing in seed nurseries requires manual hole sowing, which necessitates a hole sowing tool.

[0003] Currently, most seeding tools used for wheat breeding are complex in structure, bulky in size, and difficult to carry. They also cannot accurately control the amount of seeds to be sown in wheat breeding, and cannot automatically close the seed drop channel after sowing.

[0004] A search revealed that Chinese patent CN214852717U discloses a seeding tool for wheat breeding. During sowing, the opening device on the tool is opened to allow the seeds in the seed storage box to fall into the sowing cylinder. An elastic device is used to rotate the rotating device on the "T"-shaped cylinder, which can automatically close the seed falling channel after sowing, thus achieving free control of the seed falling amount.

[0005] In actual use, the above-mentioned hill-sowing tool for wheat breeding is a single unit. This is inconvenient for personnel who need to move frequently or work between different plots to carry around. At the same time, the large size of the single-unit hill-sowing tool also makes it inconvenient to store. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a portable hole-sowing tool for wheat breeding to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A portable hill-planting tool for wheat breeding includes a support cylinder with a storage box connected to its top. Two handles are fixedly connected to the outside of the support cylinder, and two hinge supports are fixedly connected to the outside of the support cylinder. Two foot plates are hinged inside the hinge supports, and a locking block is fixedly connected to the top of the foot plates. Two locking slots are opened on the outside of the support cylinder, and the locking block engages with the inside of the locking slots. A disassembly component is installed at the bottom of the support cylinder, and a feeding mechanism is installed inside the support cylinder.

[0009] The disassembly assembly includes a seeding head positioned below a support cylinder. Two connecting blocks are fixedly connected to the top of the seeding head. Two sliding grooves are formed at the bottom of the support cylinder, with the connecting blocks slidably connected to the inner sides of the sliding grooves. Fixed boxes are fixedly connected to both sides of the support cylinder. A threaded rod is threadedly connected inside each fixed box, with a knob fixedly connected to the top of the threaded rod and a pressing block rotatably connected to the bottom of the threaded rod. Guide rods are slidably connected to both sides of the pressing block, and the guide rods are fixedly connected to the inside of the fixed boxes. A sliding block is provided on one side of the pressing block, slidably connected to the inside of the fixed box. The cross-section of one side of the pressing block matches the cross-section of one side of the sliding block. Two first springs are fixedly connected to one side of the sliding block, with one end of each first spring fixedly connected to the inside of the fixed box. A limiting rod is fixedly connected to one side of the sliding block, penetrating the fixed box and the support cylinder and extending to the inner side of the sliding groove, where it engages with one side of the connecting block.

[0010] By adopting the above technical solution, the seed head can be quickly disassembled and installed, making it easy to store and carry when transferring it to the field.

[0011] As a further description of the above technical solution: the feeding mechanism includes a protective plate, which is fixedly connected to the inside of the support cylinder. Two feeding hoppers are fixedly connected inside the support cylinder. A turntable is rotatably connected inside the protective plate. Multiple placement slots are opened on the outer side of the turntable. A rotating rod is fixedly connected inside the turntable. Both ends of the rotating rod are rotatably connected to the inside of the support cylinder. A gear is fixedly connected to the outer side of the rotating rod. A rack meshes with one side of the gear. A pull rod is fixedly connected to the front side of the rack. A second spring is fixedly connected to one side of the rack. The top end of the second spring is fixedly connected to the inside of the support cylinder.

[0012] By adopting the above technical solution, continuous and relatively uniform feeding can be achieved during sowing, which is beneficial to improving sowing efficiency.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a disassembly component, compared with the existing technology, the threaded rod can be used to push the sliding block to move the limiting rod by squeezing the squeezing block vertically downward. This can limit the connecting block while saving the lateral volume when carrying the support cylinder, so that the support cylinder can be carried vertically. At the same time, it can make the seed head and the support cylinder quick to install and disassemble, so that it can be flexibly stored in a toolbox or backpack when moving to the field or working in different plots, making it convenient to carry.

[0015] 2. By setting up a feeding mechanism, compared with the existing technology, the turntable drives multiple placement slots to complete the feeding of wheat seeds, which makes the number of seeds more uniform during sowing and enables rapid and continuous feeding of seeds during sowing, reducing the waiting time in the sowing process and improving sowing efficiency.

[0026] The disassembly assembly includes a seeding head 8, which is located below the support cylinder 1. Two connecting blocks 9 are fixedly connected to the top of the seeding head 8. Two sliding grooves 10 are formed at the bottom of the support cylinder 1, and the connecting blocks 9 are slidably connected to the inner sides of the sliding grooves 10. Fixed boxes 11 are fixedly connected to both sides of the support cylinder 1. Threaded rods 12 are threadedly connected inside the fixed boxes 11. A knob is fixedly connected to the top of the threaded rod, and a pressing block is rotatably connected to the bottom of the threaded rod. Guide rods are slidably connected to both sides of the pressing block 14, and the guide rods are fixedly connected to the inside of the fixed boxes. A sliding block 15 is provided on one side of the pressing block 14, and the sliding block 15 is slidably connected to the inside of the fixed box 11. The cross-section of one side of the pressing block 14 matches the cross-section of one side of the sliding block 15. Two first springs 16 are fixedly connected to one side of the sliding block 15. The end is fixedly connected to the inside of the fixed box 11. A limiting rod 17 is fixedly connected to one side of the sliding block 15. The limiting rod 17 passes through the fixed box 11 and the support cylinder 1 and extends to the inside of the slide groove 10. It is engaged with one side of the connecting block 9. One end of the foot plate 5 is hinged to the inside of the hinge support 4 so that the foot plate 5 can be stored and folded. The vertical movement of the squeezing block 14 can squeeze the sliding block 15 and drive the limiting rod 17 to move. The limiting rod 17 is engaged with one side of the connecting block 9 to limit the two connecting blocks 9 so that the support cylinder 1 and the seeding head 8 can be tightly connected during sowing. During transfer, the support cylinder 1 and the seeding head 8 can be quickly disassembled and separated, so that the support cylinder 1 and the seeding head 8 can be flexibly stored in a toolbox or backpack for easy carrying.

[0027] Reference Figure 3 and 2As shown, the feeding mechanism includes a protective plate 18, which is fixedly connected to the inside of the support cylinder 1. Two feeding hoppers are fixedly connected inside the support cylinder 1. A turntable 19 is rotatably connected inside the protective plate 18. Multiple placement slots 20 are provided on the outer side of the turntable 19. A rotating rod 21 is fixedly connected inside the turntable 19. Both ends of the rotating rod 21 are rotatably connected to the inside of the support cylinder 1. A gear 22 is fixedly connected to the outer side of the rotating rod 21. A rack 23 meshes with one side of the gear 22. A pull rod 24 is fixedly connected to the front side of the rack 23. A second spring 25 is fixedly connected to one side of the rack 23. The top of the second spring 25 is fixedly connected to the inside of the support cylinder 1. The rack 23 is meshed with the gear 22, so that when the rack 23 moves downward, it can mesh with and drive the gear 22 to rotate a certain angle. The gear 22 drives the turntable 19 to rotate a certain angle inside the protective plate 18 through the rotating rod 21, so that the turntable 19 can drive the placement groove 20 to catch the fallen seeds and transport the seeds into the support cylinder 1 for sowing. The second spring 25 can drive the rack 23 to reset, so that the sowing work can be completed continuously, improving the sowing efficiency.

[0028] Working principle of this utility model: This utility model designs a portable hole-sowing tool for wheat breeding, the specific structure of which is shown in the attached instruction manual. Figure 1-7 As shown, in this technical solution, through the cooperation between various structures, when it is necessary to sow wheat seeds in holes, first hold the two handles 3 by hand, insert the seed head 8 into the appropriate sowing position, and step on the foot plate 5 to insert the seed head 8 to the appropriate depth. Then, manually pull down the lever 24, and use the lever 24 to drive the rack 23 to move downward. The rack 23 meshes with the gear 22, so that when the rack 23 moves downward, it can mesh with the gear 22 to rotate a certain angle. The gear 22 can drive the turntable 19 to rotate inside the protective plate 18 through the rotating rod 21. When the turntable 19 rotates, it can drive multiple placement slots 20 to rotate. When the placement slots 20 rotate, they can catch the wheat seeds falling downward. As the turntable 19 rotates, it can transport the wheat seeds downward into the support cylinder 1. The return force of the second spring 25 can reset the rack 23 after being pulled, so that the wheat seeds can be sown in holes.

[0029] When the support cylinder 1 needs to be carried and transported, the two foot plates 5 are bent upwards so that the locking block 6 can be inserted into the locking slot 7, thereby storing the two foot plates 5. Then, the two knobs 13 are rotated in sequence, so that the knobs 13 drive the threaded rod 12 to rotate, so that the threaded rod 12 can drive the pressing block 14 to move upwards. The two sliding blocks 15 can provide guidance for the movement of the sliding block 15, so that the cut surface on one side of the pressing block 14 can no longer press the sliding block 15, so that the sliding block 15 loses the pressing force. The return force of the two first springs 16 can push the sliding block 15 to move inside the fixed box 11, so that the sliding block 15 drives the limiting rod 17 to separate from the connecting block 9. Then, the seeding head 8 is rotated, and the seeding head 8 drives the two connecting blocks 9 to slide inside the slide groove 10. When the two connecting blocks 9 move to one end of the slide groove 10, the seeding head 8 is pulled downwards to separate the seeding head 8 from the support cylinder 1, thereby shortening the length of the support cylinder 1 for easy carrying.

Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures and will not be described here.

[0032] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
