[0033] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a quantitative sowing device for crop seeds.

[0034] A quantitative sowing device for crop seeds, comprising an electric drill 1, a bracket 2, a driving device 3 and a sifter 4, wherein the electric drill 1 is arranged at the bottom of the bracket 2, the output end of the driving device 3 is connected to the bracket 2, the driving device 3 drives the bracket 2 to move up and down, the sifter 4 comprises a shell 401, a transmission assembly and a hose 404, a disc 405 is arranged in the shell 401, a material trough 406 is arranged on the outer side of the disc 405, an inlet 407 and an outlet 408 are arranged on the shell 401, and the inlet 407 is located at the disc 406. 405, the discharge port 408 is located above the disc 405, a through groove is provided in the middle of the electric drill bit 1 which passes through to the bottom of the electric drill bit 1, one end of the hose 404 is connected with the discharge port 408, and the other end of the hose 404 is connected with the through groove, the transmission assembly is connected with the bracket 2, and the transmission assembly is connected with the disc 405 in transmission, when the driving device 3 drives the bracket 2 to move downward, the transmission assembly drives the disc 405 to rotate, so that the material trough 406 rotates from one side of the feed port 407 to one side of the discharge port 408.

[0035] The utility model is provided with an electric drill 1, a bracket 2, a driving device 3 and a material screener 4, so that when the driving device 3 does not drive the bracket 2 to move, the material trough 406 of the disc 405 is located on the side of the feed inlet 407, and a certain amount of crop seeds can enter the material trough 406 at this time. When the material trough 406 is filled with crop seeds, the crop seeds no longer enter the material trough 406; when the electric drill 1 contacts the farmland to drill holes, the driving device 3 drives the bracket 2 to move downward. At this time, since the transmission component is connected to the bracket 2, the transmission component will also move downward, and the transmission component drives the disc 405 to rotate, and the material trough 406 rotates from one side of the feed inlet 407 to one side of the discharge port 408, and a certain amount of crop seeds are discharged from the feed inlet 407. The discharge port 408 moves along the hose 404 to the electric drill bit 1 and falls into the farmland through the through groove; when the driving device 3 lifts the electric drill bit 1, the soil on both sides of the electric drill bit 1 will cover the crop seeds, and the bracket will also move upward, and the transmission component drives the disc 405 to rotate, so that the material trough 406 rotates from the side of the discharge port 408 to the side of the inlet 407, and a certain amount of crop seeds enters the material trough 406 again, and the operation is repeated. The screened crop seed particles slide through the discharge port 408 to the plastic hose 404, and finally reach the electric drill bit 1, which has the effect of precise delivery. When the electric drill bit 1 is working, it can be linked to the screener 4 to reduce the dependence on electric equipment.

[0036] The present embodiment describes a quantitative sowing device for crop seeds, wherein the transmission assembly includes a gear 402, a rack 403 and a rotating shaft 409, wherein the gear 402 is connected to the disc 405 via the rotating shaft 409, the rack 403 is connected to the bracket, and the rack 403 is meshed with the gear 402. When the driving device drives the bracket 2 to move downward, the rack 403 drives the gear 42 to rotate, so that the material trough rotates from one side of the inlet to one side of the outlet. Specifically, when the driving device 3 drives the bracket 2 to move downward, since the rack 403 is connected to the bracket 2, the rack 403 will also move downward, and the rack 403 will mesh with the gear 402. Therefore, the rack 403 synchronously drives the gear 402 to rotate, and the trough 406 rotates from one side of the inlet 407 to the side of the outlet 408; when the driving device 3 lifts the electric drill 1, the rack 403 will also move upward at the same time, and the rotation of the gear 402 drives the disc 405 to rotate, so that the trough 406 rotates from one side of the outlet 408 to the side of the inlet 407, and a certain amount of crop seeds enters the trough 406 again.

[0037] It can be understood that the outer periphery of the disc 405 is the inner wall of the shell 401. When the trough 406 rotates from one side of the inlet 407 to the side of the outlet 408, the outer side of the trough 406 is the inner wall of the shell 401. Only when it rotates to the outlet 408, the crop seeds slide out of the outlet 408.

[0038] The crop seed quantitative sowing device described in this embodiment further includes a connecting component 5, and the bracket 2 is connected to the rack 403 via the connecting component 5.

[0041] It is understandable that the electric drill bit 1 is a 37.5° pointed triangle design, and the electric drill bit 1 has a single straight row of chip grooves around it, which can directly perform deep drilling, which is smoother. The upper bracket 201 can freely adjust the length, so that it is more flexible and convenient to adapt to the planting of different crop seeds, and it can meet the planting depth of each crop from a scientific perspective. There are gaps around the electric drill bit 1 to take out the chips generated by drilling and keep the through groove clean. The electric drill bit 1 is usually made of high-hardness alloy steel or tungsten carbide and other materials, which are wear-resistant and corrosion-resistant, and improve the service life of the equipment.
