Description

Technical Field

[0001] This utility model relates to the field of handheld planting tools, specifically a handheld peanut quantitative feeding planter. Background Technology

[0002] Because peanuts are abundant and in high demand, the sowing rate is also high. Currently, peanuts are generally planted by hill sowing. Hill sowing involves digging holes in the field ridges, sowing seeds, and then covering them with soil. One or several seeds can be sown in each hole, which is called single-seed precision sowing or multi-seed hill sowing, respectively. It is suitable for crops such as corn, cotton, sugar beets, sunflowers, beans, and peanuts.

[0003] The number of seeds sown is related to the crop yield. Handheld peanut quantitative feeding seeders are beneficial to improving the efficiency of quantitative sowing and reducing labor intensity. They are often widely used in hilly and mountainous areas where large seeders cannot easily access.

[0004] However, some existing handheld peanut quantitative feeders often require staff to disassemble and replace the quantitative feeding wheel or repeatedly insert cards to adjust the quantity of peanut seeds entering the feeding chamber during quantitative feeding. The operation is cumbersome, time-consuming and labor-intensive, and peanut seeds are prone to accumulating and blocking the feeding chamber. The feeding accuracy is low, and maintenance and repair are difficult. They are inconvenient for staff to use and increase the workload of staff to a certain extent. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a handheld peanut quantitative feeder and planter to solve the technical problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a handheld peanut quantitative feeder and planter, comprising a planter, a quantitative wheel fixedly installed at one end of the planter, a push rod movably installed at one end of the quantitative wheel, a pull rod movably installed at one end of the push rod, a third spring fixedly installed at one end of the pull rod, locking blocks movably installed at both ends of the push rod, and the locking blocks and the push rod are connected by a fourth spring, a guide groove is fixedly opened at one end of the push rod, and a limit plug is movably installed on one side of the guide groove.

[0007] By adopting the above technical solution, the push rod is moved along the inner side of the metering wheel, thereby limiting the limit plug by the guide groove. This allows the limit plug to move up and down along the seed inlet groove, and, in conjunction with the limiting groove on the side of the metering wheel, positions the push rod's advancing distance. This achieves rapid and precise adjustment of the peanut seed sowing quantity. Simultaneously, when the pull rod is in position... Figure 1 When in gear, all the limit plugs will rise, which can remove the seed pellets that are blocking the seed groove.

[0008] The present invention is further configured such that a rack plate is movably installed at one end of the seeder, and the seeder and the rack plate are connected by a first spring, and a support block is fixedly installed at one end of the rack plate.

[0009] By adopting the above technical solution and installing support blocks, the device can obtain better support force and better positioning effect, making it more stable during use.

[0010] The present invention is further configured such that one end of the metering wheel is provided with ratchet teeth, and one end of the metering wheel is provided with a seed inlet groove that cooperates with the limiting plug, and the inner side of the metering wheel is provided with a limiting groove that cooperates with the locking block.

[0011] By adopting the above technical solution, the seed inlet trough can guide the seeds evenly to the correct position to achieve precise and uniform sowing. The design of the seed inlet trough can help control the seed flow and distribution, thereby improving the efficiency and quality of sowing.

[0012] The present invention is further configured such that a straight-tooth ratchet is movably mounted on one side of the ratchet teeth, and a ratchet tooth is movably mounted on the side of the straight-tooth ratchet, and the straight-tooth ratchet and the ratchet tooth are connected by a second spring.

[0013] By adopting the above technical solution and installing a straight-tooth ratchet, the self-locking function of the straight-tooth ratchet can realize the one-way transmission operation of the metering wheel, thereby realizing the purpose of the metering wheel accurately discharging the seeds downward into the duckbill mouth through the seed inlet trough.

[0014] The present invention is further configured such that a seed placement groove is provided at one end of the seeder, and a duckbill mouth is movably installed at one end of the seeder, and the rack plate and the straight tooth ratchet are meshed together.

[0015] By adopting the above technical solution, the transmission method is made more stable through the meshing connection of the rack plate and the spur ratchet, the device structure is more perfect, and the operation is more stable.

[0016] The present invention is further configured such that the number of limiting plugs is six sets, and each set has three limiting plugs, and the limiting groove is four sets.

[0017] By adopting the above technical solution and setting four sets of limiting grooves, a multi-stage adjustable seeding and feeding mode can be realized, enabling quantitative operation of the number of seeds fed, simplifying the operation steps, and making it convenient for staff to use.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention incorporates a metering wheel, a push rod, a pull rod, and limiting plugs. Pulling the pull rod releases one end from the limiting block. Pushing the push rod moves it along the inner side of the metering wheel, causing the limiting plug to be limited by a guide groove. This allows the limiting plug to move up and down along the seed inlet groove. The limiting groove on the side of the metering wheel positions the push rod's advance distance, enabling precise adjustment of the peanut seed planting quantity quickly. Simultaneously, when the pull rod is in the limited position shown in the diagram, all limiting plugs will rise, ejecting seeds blocking the seed inlet groove. Releasing the pull rod allows it to re-lock the limiting block under the action of a third spring. This design facilitates use, saves debugging time, improves feeding accuracy, increases work efficiency, and reduces worker workload. Attached Figure Description

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A handheld peanut metering planter, such as Figure 1-4As shown, the device includes a seeder 1. A metering wheel 12 is fixedly installed at one end of the seeder 1, and a push rod 5 is movably installed at one end of the metering wheel 12. A pull rod 16 is movably installed at one end of the push rod 5, and a third spring 17 is fixedly installed at one end of the pull rod 16. Locking blocks 18 are movably installed at both ends of the push rod 5, and the locking blocks 18 and the push rod 5 are connected by a fourth spring 19. A guide groove 20 is fixedly opened at one end of the push rod 5, and a limit plug 21 is movably installed on one side of the guide groove 20. By pulling the pull rod 16, the limit block 18 is released at one end. By pushing the push rod 5, the push rod 5 moves along the inner side of the metering wheel 12, thereby limiting the limit plug 21 by the guide groove 20. This allows the limit plug 21 to move up and down along the seed inlet groove 14, and, in conjunction with the limit groove 15 on the side of the metering wheel 12, positions the push rod 5 to advance a certain distance, thereby achieving precise adjustment of the number of peanut seeds sown quickly.

[0028] Please see Figure 1 A rack plate 7 is movably installed at one end of the seeder 1, and the seeder 1 and the rack plate 7 are connected by a first spring 8. A support block 4 is fixedly installed at one end of the rack plate 7. By installing the support block 4, the device can obtain better support force and better positioning effect, making the device more stable during use.

[0029] Please refer to the figure. One end of the metering wheel 12 has ratchet teeth 13, and the other end of the metering wheel 12 has a seed inlet groove 14 that cooperates with the limiting plug 21. The inner side of the metering wheel 12 has a limiting groove 15 that cooperates with the locking block 18. By opening the seed inlet groove 14, the seed inlet groove 14 can guide the seeds evenly to the correct position to achieve precise and uniform sowing. The design of the seed inlet groove 14 can help control the seed flow and distribution, and improve the efficiency and quality of sowing.

[0030] Please see Figure 3 A straight-tooth ratchet 9 is movably mounted on one side of the ratchet tooth pattern 13, and a ratchet tooth 10 is movably mounted on the side of the straight-tooth ratchet 9. The straight-tooth ratchet 9 and the ratchet tooth 10 are connected by a second spring 11. By installing the straight-tooth ratchet 9, the self-locking function of the straight-tooth ratchet 9 can realize the one-way transmission operation of the metering wheel 12, thereby realizing the purpose of the metering wheel 12 accurately discharging the seeds downward into the duckbill mouth 3 through the seed inlet trough 14.

[0031] Please see Figure 3 The seeder 1 has a seed trough 6 at one end and a duckbill mouth 3 is movably installed at the other end. The rack plate 7 and the straight tooth ratchet 9 are meshed together. Through the meshing connection of the rack plate 7 and the straight tooth ratchet 9, the transmission method is more stable, the device structure is more perfect, and the operation is more stable.

[0032] Please see Figure 4The number of limit plugs 21 is set in six groups, and each group has three limit plugs 21. The number of limit grooves 15 is set in four groups. By setting four groups of limit grooves 15, the multi-stage adjustment of the seeding and feeding mode can be realized, the quantitative operation of the number of seeds fed can be realized, the operation steps can be simplified, and the staff can use it conveniently.

[0033] The working principle of this utility model is as follows: First, peanut seeds are poured into the seed trough 6, and the quantity of seeds required for sowing is determined according to the soil conditions. Then, by pulling the lever 16, one end of the lever 16 is released from its limiting position on the locking block 18. Pushing the push rod 5 causes it to move along the inner side of the metering wheel 12, thereby limiting the locking plug 21 to the guide groove 20. This allows the locking plug 21 to move up and down along the seed inlet trough 14, and, in conjunction with the limiting groove 15 on the side of the metering wheel 12, positions the push rod 5 to adjust its advancing distance. This achieves rapid and precise adjustment of the peanut seed sowing quantity. After the lever 16 is released, the locking block 18 is controlled by the fourth spring 19. After resetting, lever 16 can re-lock block 18 under the action of third spring 17. At this time, the sowing operation can be started by holding handle 2. Press the sower 1 downwards to align with the pre-sowing area, so that the duckbill mouth 3 can be smoothly inserted into the soil. At this time, support block 4 is squeezed and moves vertically, so that rack plate 7 meshes with and drives spur ratchet 9 to rotate. Under the action of ratchet system, spur ratchet 9 limits the transmission of ratchet teeth 13 through ratchet teeth 10, so that metering wheel 12 rotates to one side, so that peanut seeds can be smoothly buried in the soil through duckbill mouth 3, and rack plate 7 is reset under the action of first spring 8. After the sowing work is completed, the operation is complete.
