[0002] A seeder is an agricultural machine used in the prior art for sowing on large areas of land. It is favored by growers because of its high sowing efficiency, replacing the manual sowing method used in traditional technology.
[0003] In the prior art, a seeder consists of two parts: a traveling wheel and an armrest frame connected to the traveling wheel. The traveling wheel is a main component assembly, which generally includes a seed box, an inner wheel body connected to the seed box, side covers rotatably connected to both sides of the inner wheel body through a rotating shaft, and a plurality of duckbill assemblies detachably connected to the two side covers around the circumference of the traveling wheel. The sowing work of the seeder is mainly completed by the duckbill assembly, which generally includes a base plate, a sowing nozzle connected to the base plate and capable of opening and closing, and an elastic lever connected to the base plate and used to control the opening and closing of the sowing nozzle.
[0004] Current seeders generally have installation positions pre-arranged on the two side panels, and then users only need to connect the base plate in each duckbill assembly to the two side panels by means of snap-on connection or screw connection to complete the installation of several duckbill assemblies. However, in actual use, the sowing density is different for different seed materials. Due to the uniqueness of the installation and the coordination with the base plate, users cannot adaptively adjust the spacing of the duckbill assemblies, which makes the applicability of the seeder poor. For the sowing of different seed materials, users can only purchase seeders of different models (different models of seeders have different spacings of duckbill assemblies) to carry out sowing work. Summary of the invention
[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a seeder with an adjustable duckbill. The technical problem to be solved by the utility model is: how to improve the applicability of the seeder.
[0006] The purpose of the utility model can be achieved through the following technical solutions: a seeder with an adjustable duckbill, comprising two side panels that are disc-shaped and arranged opposite to each other, the duckbill having a plurality of and each of the duckbill comprising a rectangular and curved bottom plate, characterized in that the seeder with an adjustable duckbill also comprises a plurality of rectangular and curved adjustment plates, each of the bottom plates and each of the adjustment plates are detachably connected to the two side panels, and each of the bottom plates and each of the adjustment plates can slide and position along the circumference of the two side panels, and a plurality of the duckbill and a plurality of the adjustment plates are alternately arranged one by one along the circumference of the two side panels, and one of the adjustment plates and one of the bottom plates are screwed and locked with the two side panels by fasteners.
[0007] The present invention relates to a seeder with adjustable duckbills, comprising a plurality of duckbills, two side panels rotatably connected to both sides of an inner box body, and a plurality of adjusting plates. Compared with the prior art, the present invention is different in that the plurality of duckbills and the plurality of adjusting plates are connected to the two side panels in a detachable manner. Specifically, each duckbill comprises a bottom plate, which is rectangular and curved in an arc shape, which is more consistent with the outer contour of the two side panels. Each duckbill and each adjusting plate are connected to the two side panels along the circumference of the two side panels in a sliding connection manner, and the plurality of adjusting plates and the plurality of duckbills are specifically arranged alternately between the two side panels, so that two adjacent duckbills are separated by the existence of the adjusting plate to ensure that the sowing spacing meets the actual requirements. On the other hand, the two side panels can be used as universal parts to match different Duckbills and adjustment plates of the same size are assembled. When a smaller sowing spacing is required, a duckbills with shorter bottom plates and a shorter adjustment plate can be used for assembly with two side plates, so that the spacing between two adjacent duckbills is smaller.
