Reversing mechanism of rice precision hill-drop planter and rice precision hill-drop planter

Abstract

The invention discloses a reversing mechanism of a rice precision hill-drop planter and the rice precision hill-drop planter. The reversing mechanism of the rice precision hill-drop planter comprises a connecting mechanism for connecting a seed feeding setting mechanism and two groups of conveying mechanisms; the connecting mechanism is provided with two output ports which are communicate with the conveying mechanisms respectively; the two groups of conveying mechanisms are conveying belts for horizontal conveying; a plurality of seed storage boxes are arranged on the outer surfaces of the conveying belts side by side in the length direction of the conveying belts; the output ports communicate with the seed storage boxes; the connecting mechanism is provided with a mounting shaft; a connecting piece arranged outside the connecting mechanism in a sleeving mode is fixed to the mounting shaft; a blocking piece is rotationally connected to the position, located in the connecting mechanism, of the mounting shaft; and the conveying mechanism is provided with a first matching structure and a second matching structure which can enable the blocking piece to periodically rotate and close one of the output ports. The reversing mechanism has the beneficial effects that a mechanical structure mode is adopted to replace electric control, so that control is more reliable, and the rice yield is effectively improved.

Description

technical field [0001] The invention relates to the field of rice planters, in particular to a reversing mechanism of a rice precision hole sower and the rice precision hole sower. Background technique [0002] The rice direct seeding cultivation technology is a cultivation method in which rice seeds are directly sown in the field without raising seedlings and transplanting; compared with cultivated rice, this technology simplifies the rice cultivation process, reduces labor intensity, and alleviates seasonal conflicts. , labor-saving, labor-saving, seedling-saving, high-yield and high-efficiency advantages, at present, it has gradually become an important cultivation method for rice production. [0003] Most of the current rice seeders are purely mechanical, and the control accuracy of the number of rice grains sown in each hole is not high, and too many or too few seeds will affect the quality of sowing, thereby directly affecting the yield of rice. [0004] The existing ...

Problems solved by technology

[0003] Most of the current rice seeders are purely mechanical. The control accuracy of the number of rice grains sown in each hole is not high, and too many or too few seeds will affect the quality of sowing, which directly affects the yield of rice.

[0004] The existing Chinese patent application number CN201810078116.5 discloses a rice precision hole seeder, including a frame, and also includes a grain feeding setting area, a counting and screening area, a rotary transmission area, Funnel granulation area, at least one group is installed in the granule feeding setting area, the counting and screening area, the rotary transfer area, and the hopper granulating area; A particle feeding brush, the slide setting plate is arranged obliquely, and the feed port is located above the upper end of the slide setting plate, the particle feeding brush is located above the lower end of the slide setting plate; the counting and screening area is located at the feeding Below the particle brush, it includes the counting induction area at the upper end and the screening control part at the lower end; the rotary transfer area is located below the screening control part, and each group of the rotary transfer area includes two transfer discs installed side by side, and the The rotating shaft of the transmission disc is set horizontally. The hole planter with this structure can accurately control the number of rice grains planted in each hole, thereby increasing the yield of rice, but there are still defects. In the above scheme, the screening control part adopts an electronic control method To realize switching between channels, there are many factors affecting the electronic control method, and the control reliability is relatively unreliable compared with mechanical control. Once there is a problem with the control motor, the switching of channels will be blocked, thus affecting the control of sowing
