Description

Technical Field

[0001] The utility model relates to the field of seeding devices, in particular to a handheld high-precision peanut seeding device. Background Technique

[0002] A seeding machine is a planting machine that takes crop seeds as the seeding object. For a seeding machine for a certain type or kind of crop, it is often named after the crop type, such as a cereal drill, a corn hill-drop planter, a cotton seeding machine, a peanut seeding machine, etc. To facilitate the subsequent use by workers, it has been extended to a high-precision peanut seeding device or an electric seeding device, etc.

[0003] Most peanut seeding machines are composed of components such as a feeding pipe, a handle, and a soil-opening plate. Workers place the peanut raw materials to be sown into the feeding pipe, manually control the position of the peanut seeding machine, and send the peanut raw materials into the soil through the soil-opening plate to complete the seeding of peanuts.

[0004] However, for most existing peanut seeding machines, when opening the soil through the soil-opening plate to complete the seeding of peanuts, the soil on both sides of the seed pit cannot automatically reset. It is necessary for subsequent workers to manually level it with tools to ensure the normal growth and development of subsequent peanut seeds. However, manually ramming the soil by workers will affect the overall seeding efficiency and increase the working intensity of workers, which is rather inconvenient. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a handheld high-precision peanut seeding device to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A handheld high-precision peanut seeding device includes a feeding pipe. One end of the feeding pipe is fixedly installed with a handle, and one end of the feeding pipe is fixedly installed with a soil-opening plate. A threaded rod is movably installed inside the feeding pipe, and a gear is fixedly installed in the middle of the threaded rod. One end of the threaded rod is movably installed with a push plate, and a limiting plate for limiting the push plate is fixedly installed at one end of the threaded rod. A driving component for driving the threaded rod is movably installed inside the feeding pipe.

[0007] By adopting the above technical solution, by providing components such as threaded rods, racks, push plates, extrusion blocks, limit blocks and limit grooves, when workers sow peanuts through the soil-opening plate and the feeding pipe, the extrusion block contacts the soil, causing the rack to drive the threaded rod to rotate. That is, after the workers complete sowing the peanuts, the push plates on both sides can move towards each other, pushing the soil on both sides of the seed pit back into the pit to cover the sown peanut seeds. Compared with the traditional manual method of leveling and tamping the land by workers, this device is more convenient and fast. Through the downward force during sowing, the soil generated during pit-opening can be automatically reset, effectively improving the overall sowing efficiency and reducing the working intensity of workers.

[0008] The present utility model is further configured such that the driving assembly includes an extrusion block, a rack, a connecting rod, a spring and an activity groove. A spring is fixedly installed inside the feeding pipe, and one end of the spring is fixedly installed with a connecting rod, and one end of the connecting rod is fixedly installed with an extrusion block.

[0009] By adopting the above technical solution, the fixedly installed spring prevents it from detaching from the feeding pipe, and at the same time, it continuously applies elastic force to the connecting rod. The fixedly installed extrusion block causes the extrusion block to drive the connecting rod to move together during movement. After the extrusion is removed, the elastic force of the spring helps it to reset, ensuring that it can work normally to control the threaded rod.

[0010] The present utility model is further configured such that an activity groove for the movement of the connecting rod is provided inside the feeding pipe, and a rack meshing with the gear is fixedly installed at one end of the extrusion block.

[0011] By adopting the above technical solution, the fixedly installed rack causes the extrusion block to drive the rack to move together when moving, and the rack meshes with the gear, so that when the rack moves up or down, the rack drives the gear to rotate to drive the threaded rod. The activity groove allows the connecting rod to move inside the feeding pipe, and at the same time, the activity groove can limit the connecting rod to ensure its moving direction.

[0012] The present utility model is further configured such that a limit block is fixedly installed at one end of the rack, and a limit groove for restricting the limit block is provided inside the feeding pipe.

[0013] By adopting the above technical solution, the cooperation of the limit block and the limit groove enables the limit block to restrict the rack to ensure the moving direction of the rack, and at the same time effectively prevents the rack from detaching from the inside of the feeding pipe, ensuring that the rack can normally drive the gear.

[0014] The present utility model is further configured such that a limit rod for limiting the push plate is fixedly installed at one end of the feeding pipe, and the bottom end face of the push plate is provided with an arc shape.

[0015] By adopting the above technical solution, the limiting rod can restrict the pushing plate to prevent the pushing plate from rotating together with the threaded rod, ensuring the moving direction of the pushing plate. The bottom surface of the pushing plate is arranged in an arc shape, enabling it to better push the soil on both sides of the seed pit into the seed pit to bury the peanut seeds.

[0016] The present utility model is further configured such that the limiting blocks, limiting grooves, racks, pushing plates, and limiting rods are all symmetrically arranged in two groups, and the threads at both ends of the threaded rod are respectively right-handed and left-handed. Threads matching the threaded rod are provided inside the pushing plates.

[0017] By adopting the above technical solution, the multiple symmetrically arranged limiting blocks, limiting grooves, racks, pushing plates, and limiting rods enable the extrusion block to better drive the threaded rod to rotate through the two racks and two gears during movement. The threads at both ends of the threaded rod are respectively right-handed and left-handed, enabling the two symmetrically arranged pushing plates to move in opposite directions when the threaded rod rotates, so that the pushing plates can better push the soil into the seed pit from both sides, eliminating the subsequent manual backfilling of the soil by workers and improving the overall seeding efficiency.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] By providing components such as a threaded rod, a rack, a pushing plate, an extrusion block, a limiting block, and a limiting groove, when workers sow peanuts through the soil-opening plate and the feeding pipe, the extrusion block contacts the soil and the rack drives the threaded rod to rotate. After the workers complete sowing the peanuts, the pushing plates on both sides can move in opposite directions to push the soil on both sides of the seed pit back into the pit to cover the sown peanut seeds. Compared with the traditional manual leveling and tamping of the land by workers, this device is more convenient and fast. Through the downward force during sowing, the soil generated during pit-opening can be automatically reset, effectively improving the overall seeding efficiency and reducing the working intensity of workers.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0026] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0027] A handheld high-precision peanut seeding device, as Figures 1-4 shown, includes a blanking pipe (1). One end of the blanking pipe (1) is fixedly installed with a handle (2), and one end of the blanking pipe (1) is fixedly installed with a soil-opening plate (3). A threaded rod (6) is movably installed inside the blanking pipe (1), and a gear (7) is fixedly installed in the middle of the threaded rod (6). One end of the threaded rod (6) is movably installed with a push plate (8), and a limit plate (10) for limiting the push plate (8) is fixedly installed at one end of the threaded rod (6). A driving component for driving the threaded rod (6) is movably installed inside the blanking pipe (1). Workers put peanut seeds into the blanking pipe 1. Workers control its overall position through the handle 2 and press the blanking pipe 1 at the place where seeding is required. The soil-opening plate 3 provides space for the peanut seeds to enter the soil. During its movement, one end of the extrusion block 4 contacts the soil, causing the rack 5 to drive the threaded rod 6 to rotate, so that the push plates 8 on both sides of the threaded rod 6 move towards each other. The push plates 8 push the soil on both sides of the seed pit into the seed pit to bury the peanut seeds that have entered the pit and ensure the normal growth of peanuts.

[0028] Please refer to Figure 2 - Figure 4 , the driving component includes an extrusion block 4, a rack 5, a connecting rod 11, a spring 12 and a movable groove 15. A spring 12 is fixedly installed inside the blanking pipe 1, and one end of the spring 12 is fixedly installed with a connecting rod 11. One end of the connecting rod 11 is fixedly installed with an extrusion block 4. The fixedly installed spring 12 makes it not break away from the blanking pipe 1, and at the same time it continuously exerts an elastic force on the connecting rod 11. The fixedly installed extrusion block 4 makes the extrusion block 4 drive the connecting rod 11 to move together during movement. After the extrusion is removed, the elastic force of the spring 12 will help it reset to ensure that it can work normally to control the threaded rod 6.

[0029] Please refer to Figure 3- Figure 4 A movable groove 15 for the connecting rod 11 to move is provided inside the discharge tube 1. A rack 5 meshing with the gear 7 is fixedly installed at one end of the extrusion block 4. The fixedly installed rack 5 enables the extrusion block 4 to drive the rack 5 to move together when it moves, and the rack 5 meshes with the gear 7, so that when it moves up or down, the rack 5 drives the gear 7 to rotate, driving the threaded rod 6. The movable groove 15 allows the connecting rod 11 to move inside the discharge tube 1, and the movable groove 15 can limit the connecting rod 11 to ensure its moving direction.

[0030] See also Figure 3 - Figure 4 A limit block 13 is fixedly installed at one end of the rack 5, and a limit groove 14 is opened inside the discharge tube 1 to limit the limit block 13. The limit block 13 cooperates with the limit groove 14 so that the limit block 13 can limit the rack 5 to ensure the moving direction of the rack 5, and at the same time effectively prevent the rack 5 from escaping from the discharge tube 1, ensuring that the rack 5 can drive the gear 7 normally.

[0031] See also Figure 2 - Figure 3 A limiting rod 9 for limiting the push plate 8 is fixedly installed at one end of the discharge pipe 1, and the bottom end surface of the push plate 8 is set in an arc shape. The limiting rod 9 can limit the push plate 8 to prevent the push plate 8 from rotating with the threaded rod 6, thereby ensuring the moving direction of the push plate 8. The bottom surface of the push plate 8 is set in an arc shape, so that it can better push the soil on both sides of the seed pit into the seed pit to bury the peanut seeds.

[0032] See also Figure 1 - Figure 4 The limit block 13, the limit groove 14, the rack 5, the push plate 8 and the limit rod 9 are all symmetrically arranged in two groups, and the threads at both ends of the threaded rod 6 are right-handed and left-handed respectively. The push plate 8 is provided with a thread matching the threaded rod 6 inside. Multiple groups of symmetrically arranged limit blocks 13, limit grooves 14, racks 5, push plates 8 and limit rods 9 enable the extrusion block 4 to better drive the threaded rod 6 to rotate through the two groups of racks 5 and the two groups of gears 7 during the movement. The threads at both ends of the threaded rod 6 are right-handed and left-handed respectively, so that the two groups of symmetrically arranged push plates 8 can make opposite movements when the threaded rod 6 rotates, so that the push plate 8 can better push the soil into the seed pit from both sides, eliminating the need for subsequent workers to manually backfill the soil, thereby improving its overall sowing efficiency.

[0033] The working principle of the present utility model is as follows: When a worker uses this device, the worker puts peanut seeds into the feeding pipe 1, and the worker controls the overall position through the handle 2. When it is necessary to sow, the feeding pipe 1 is pressed at the place where sowing is required. The soil-opening plate 3 first contacts the soil, providing space for the peanut seeds to enter the soil interior. During its movement, one end of the extrusion block 4 contacts the soil, causing the rack 5 to drive the threaded rod 6 to rotate, so that the push plates 8 on both sides of the threaded rod 6 move towards each other. The push plates 8 are restricted by the limiting rods 9, so that they cannot rotate together with the threaded rod 6, ensuring the moving direction of the push plates 8. The push plates 8 push the soil on both sides of the seed pit into the seed pit interior, burying the peanut seeds that have entered the pit, ensuring the normal growth of peanuts. After sowing is completed, the worker raises the position of the feeding pipe 1, and the extrusion block 4 is reset under the influence of the elastic force of the spring 12 and its own gravity, ensuring that it can normally reset the soil next time, greatly improving the overall sowing efficiency.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principle and purpose of the present utility model, make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
