Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeder technology, specifically a handheld quantitative seeder. Background Technology
[0002] With the development of technology, agricultural production has gradually become mechanized. Compared with traditional manual sowing, large-scale mechanical sowing is faster and saves time and labor. Currently, in the plains of Inner Mongolia and other regions, mechanical sowing is favored by farmers and herdsmen. However, in mountainous and hilly areas, due to the rugged terrain and complex topography, large agricultural machinery has difficulty entering the work area, and manual sowing is the only option. Furthermore, in scientific research, small-area sowing is often used. In such cases, manual sowing is the only option. However, manual sowing is slow, time-consuming, and labor-intensive. Therefore, in the existing technology, the patent technology with Chinese patent authorization number CN222621589U has improved the above problems. Although it can effectively improve the sowing efficiency and control the sowing amount, it has been found that this technology uses a sliding insert to open and close the seed outlet and adjust the size of the seed outlet. The seed outlet has a V-shaped design, and seeds of different sizes are mixed together. As the sliding insert rises, large seeds are discharged by gravity, and small seeds are also discharged at the same time. Therefore, this is a challenge for sowing seeds of different sizes, and there is also the problem of large seed discharge in the same area. To address this, we propose a handheld quantitative seeder. Utility Model Content
[0003] The purpose of this invention is to provide a handheld quantitative seeder to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a handheld quantitative seeder, comprising a loading cylinder, a distributing pipe connected to the middle of the loading cylinder, a separator fixedly installed on the distributing pipe, multiple inlet holes opened from top to bottom on the distributing pipe, the lowest point of each inlet hole being flush with the lowest point of the separator, a pouring pipe fixedly connected to the bottom of the loading cylinder, the pouring pipe and the distributing pipe being fixedly connected together, multiple first magnets fixedly installed on the inner ring of the top of the distributing pipe, an outer tube rotatably connected to the middle of the distributing pipe, multiple second magnets fixedly connected to the outer ring of the outer tube, the second magnets and the first magnets having opposite magnetic poles attracting each other.
[0005] Preferably, the separator is composed of multiple perforated plates that are fixedly installed on the distribution pipe at equal intervals from top to bottom. The perforated plates are depressed in the middle and have multiple discharge holes on their surface. The diameter of the discharge holes on the perforated plates located at the highest point inside the loading cylinder and the discharge holes on the perforated plates located at the lowest point inside the loading cylinder decreases from top to bottom.
[0006] Preferably, multiple baffles are fixedly installed on the outside of the outer tube. The baffles have openings that are adapted to the size of the inlet holes. The multiple inlet holes are spirally distributed on the distribution tube, and the orientations of two adjacent inlet holes are staggered.

[0008] Preferably, multiple limiting plates are installed at equal intervals on one side of the loading cylinder, and an insert plate is installed at the bottom of the through rod. The distance between two adjacent limiting plates and the thickness of the insert plate are equal.
[0009] Preferably, handles are fixedly installed at both ends on the other side of the loading cylinder, and a shoulder strap is installed on the outside of the loading cylinder.
[0010] Compared with the prior art, the beneficial effects of this utility model are: The downward collapse of the middle section of the sluice plate in this invention increases the rolling speed of the seeds. The separator is used to separate seeds of different particle sizes. The seeds are manually poured into the loading cylinder, which is then shaken to separate the seeds into layers on the separator. The seeds are then taken to the outdoor work site, where the discharge pipe is opened to discharge them. The smaller seeds are discharged first at the bottom layer, and then sown in the field. The device improves the efficiency of seed sorting and rarely causes large and small particles to mix together due to gravity. Attached Figure Description

Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-4 This utility model provides a technical solution: a handheld quantitative seeder, including a loading cylinder 1, a distributing pipe 5 connected to the middle of the loading cylinder 1, a separator 4 fixedly installed on the distributing pipe 5, multiple inlet holes 18 opened from top to bottom on the distributing pipe 5, the lowest point of each inlet hole 18 being flush with the lowest point of the separator 4, a pouring pipe 3 fixedly connected to the bottom of the loading cylinder 1, the pouring pipe 3 and the distributing pipe 5 being fixedly connected together, multiple first magnets 6 fixedly installed on the inner ring of the top of the distributing pipe 5, an outer pipe 8 rotatably connected to the middle of the distributing pipe 5, multiple second magnets 7 fixedly connected to the outer ring of the outer pipe 8, the second magnets 7 and the first magnets 6 having opposite magnetic poles and attracting each other; the separator 4 is composed of multiple perforated plates 15 fixedly installed at equal intervals from top to bottom on the distributing pipe 5, the middle of the perforated plates 15... The soil is collapsed, and its surface has multiple discharge holes. The diameter of the discharge holes on the highest part of the discharge plate 15 inside the filling cylinder 1 decreases from top to bottom to the lowest part of the discharge plate 15 inside the filling cylinder 1. The downward collapse of the middle part of the discharge plate 15 can increase the rolling speed of the seeds. The separator 4 is used to separate seeds of different particle sizes. First, the seeds are poured into the filling cylinder 1 manually. Then the filling cylinder 1 is shaken to store the seeds in layers on the separator 4. Then they are taken to the outdoor operation scene, and the discharge pipe 3 is opened to discharge the seeds. The smaller seeds are discharged first at the bottom layer. They can be sown in the field in sequence. The device improves the seed classification efficiency and rarely causes large and small particles to mix together due to gravity.
[0015] Furthermore, multiple baffles 17 are fixedly installed on the outside of the outer tube 8. The baffles 17 have openings that are adapted to the diameter of the inlet holes 18. The multiple inlet holes 18 are spirally distributed on the distribution tube 5, and the orientation of two adjacent inlet holes 18 is staggered. The baffles 17 can be manually rotated to block the inlet holes 18 on the outer tube 8, so that the seeds on the different layers of the perforated plates 15 can be discharged. When the seeds on one layer of the perforated plate 15 are discharged, the inlet holes 18 next to the perforated plates 15 of other layers are blocked. Therefore, selective sowing can be carried out in a certain area, improving the controllability of the device for selective sowing.
[0016] Furthermore, an inner rod 10 is slidably connected to the outer tube 8, a bearing 11 is fixedly installed on the top of the outer tube 8, a spring 9 is fixedly connected between the top of the inner rod 10 and the top of the outer tube 8, a pressure plate 12 is fixedly installed on the outer ring of the bearing 11, a through rod 13 is movably connected to the outside of the loading cylinder 1, the pressure plate 12 and the through rod 13 are rotatably connected, and multiple flow-limiting plates 16 are fixedly installed on the outside of the inner rod 10. The surface size of the flow-limiting plates 16 is equal to the opening of the inlet hole 18 and the baffle 17. During the sowing process, the through rod 13 can be pressed manually to make the spring 9 so that the baffle 17 can be adjusted at the inlet hole 18 to control the flow rate of seeds passing through the inlet hole 18 on each layer of the perforated plate 15, thus solving the problem of large seed discharge in the same area.
[0017] Furthermore, multiple limiting plates 14 are installed at equal intervals on one side of the loading cylinder 1, and an insert plate is installed at the bottom of the through rod 13. The distance between two adjacent limiting plates 14 is equal to the thickness of the insert plate. After the through rod 13 is rotated, it is inserted between two adjacent insert plates to lock the position of the through rod 13. This locks the baffle 17 at the upper and lower heights of the inlet hole 18, freeing up manual labor and reducing the burden.
[0018] Furthermore, handles 2 are fixedly installed at both ends on the other side of the loading cylinder 1, and a shoulder strap is installed on the outside of the loading cylinder 1 to improve the portability of the device.
