A small particle no-tillage and film precision seeder

Abstract

A small particle type precise no-tillage and on-film sower comprises a frame, a seed box is arranged above a frame, guide tubes are arranged at the lower end of the seed box, the other ends of the guide tubes are connected with wheel disc type duckbilled sowing mechanisms, and the wheel disc type duckbilled sowing mechanisms are connected with the frame via fixing devices. Each fixing device comprises a fixing plate, one end of the fixing plate is arranged on the frame, a pre-tensioning device is arranged at the upper end of the fixing plate, and the other end of the pre-tensioning device is in shaft connection with the upper portion of one H-shaped fixing rod. One end of each H-shaped fixing rod is movably connected with the lower end of each fixing plate, and the other end of the H-shaped fixing rod is connected with the wheel disc type duckbilled sowing mechanisms. The small particle type precise no-tillage and on-film sower is good in profile modeling and capable of completing punching at one time and precisely sowing, can sow six rows at one time, and is high in sowing efficiency and applicable to different terrains and different seeds, and use value of the sower is maximized.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a small-grain type precision seeder on a membrane suitable for northwest dry farming areas. Background technique [0002] The mechanized conservation tillage system is a farming system that preserves water and soil, and increases production and income. It is different from the plough that turns the soil in an all-round way. It covers a large amount of straw residues on the surface and reduces the tillage to ensure that the seeds germinate, thereby reducing soil erosion and soil moisture evaporation. my country's experimental research on the soil working parts of no-till planters has just begun, and the problem of clogging of no-till planters in my country still exists, and various anti-clogging devices cannot fundamentally solve the clogging. The impact of sowing quality due to grass blocking is an urgent problem to be solved in no-tillage mulching and direct seed...

Problems solved by technology

The cam-type tearing film is more serious, and the in-line type is seldom studied, and it is difficult to establish in theory. The current in-line mechanical tearing film phenomenon is also serious. However, only the duckbill type is widely used and the technology is relatively mature. However, due to the single structure of many duckbill machines on the market, it is impossible to copy and adjust the seeding rate, and even the phenomenon of missed sowing is serious. The seeding rate cannot be adjusted, and the use value of the machine is not maximized
