Description
The utility model relates to the structure of agricultural seeding machine, a kind of specifically sower covering device.
China is the numerous big country of agricultural population, current high speed development of national economy has also promoted Agricultural Development, fast-developing agricultural requires the support of advanced agricultural machinery, in numerous agricultural machinery, sower is the agricultural tool that is most widely used, and seeding operation directly influences sowing, fertilising quality and the farm output of crops, existing sower is further improved and is perfect, increase kind, to adapt to different regions, the requirement of Different Crop.
The purpose of this utility model provides a kind of sower covering device, and its exert pressure elastic force and terrain clearance are adjustable, adapt to the requirement of the sowing earthing of multiple kinds of crops, reach the emergence rate height, and seedling is strong consistent, improves the purpose of output.
The purpose of this utility model is achieved in that
A kind of sower covering device is installed on the forward and backward beam of sower frame, and covering device is positioned at the rear of seed opener, it is characterized in that:
Covering device is made up of earthing pipe, rake teeth, towing bracket and depth adjusting rod, accent canister spring;
The horizontal long tube of earthing Guan Weiyi, its downside is connected with some rake teeths, and the place ahead is at interval suitably apart from being connected with two traction connecting plates on the earthing pipe;
Towing bracket comprises two elongated draw bars, and its rear end is connected with the traction connecting plate, and its front end is articulated in bearing, and this bearing is installed in to be adjusted on the beam;
Depth adjusting rod is a slender rod piece, there are left and right two, the back rest that frame is passed in its upper end is located with split pin, its lower end and towing bracket are hinged with split pin, its middle part is arranged with the spring-loaded packing ring with the split pin location, is set with to transfer dark compression spring on the depth adjusting rod external diameter between this spring-loaded packing ring and the back rest lower surface.
The purpose of this utility model can also realize by following measure:
The bearing of described free drawbar is made up of preceding bearing and rear plate, and preceding bearing and rear plate face one another with bolt and pass the narrow slit of adjusting beam and clamping is anchored on the adjustment beam of frame.
The pin-and-hole of spring-loaded pad alignment pin is worn at the pin-and-hole of wearing the locating aperture pin, the middle part of described depth adjusting rod upper end and the draw bar and the depth adjusting rod lower end of towing bracket is provided with several with the hinged pin-and-hole of split pin, thereby can regulate the terrain clearance of the elastic force and the earthing pipe of canister spring.
The utility model at seeding time, at first suitably adjust canister spring elasticity, so that reach suitable effect, the stigma that sowing the time brings is leaked in the disposable covering of the seed of outside, cover smoothly, improved the emergence rate of wheat greatly, increased the output of wheat, the sower that does not have covering device, the late 3-4 of going out of the wheat days time that the wheat that its preceding plough is broadcast is broadcast than post-trenching device, the Miao Youxi that comes out, not only weak but also yellow.Because sower all is front and back two row, add the sowing of defective ejaculation amount again, must keep emergence rate height, the effect of competence exertion mechanization.The utility model has been realized peasant's wish, thereby has solved the difficult and complicated illness of bringing when sowing for many years, and the sower of covering device is arranged, the seedling that grows is strong to be consistent, this covering device is the desirable facility that sower must be equipped with, and realizes the operation of mechanization, has solved peasant brother's trouble and worry.
