Grass seed filtering and collecting device

Abstract

The invention discloses a grass seed filtering and collecting device. The grass seed filtering and collecting device comprises a handheld guide pipe, a grass seed filtering assembly, a backpack-type machine frame and a power output device and a centrifugal pump which are installed on the backpack-type machine frame. The power output device is connected with the centrifugal pump. The grass seed filtering assembly comprises a triangle bottom base of which the front end is opened, a flow guiding shrinkage part slantwise upwards expanding to two sides along an opening of the triangle bottom base,and a filtering part slantwise upwards installed along the flow guiding shrinkage part. A liquid inlet at the bottom end of the handheld guide pipe is suspended and installed on the triangle bottom base. A liquid outlet at the top end of the handheld guide pipe is communicated with a liquid inlet of the centrifugal pump. A liquid outlet of the centrifugal pump is communicated with a grass seed collector. The grass seed filtering and collecting device is capable of realizing the filtration and collection of grass seeds through one device, the operation is convenient, and the working efficiencyis high.

Description

technical field [0001] The invention relates to the technical field of field agricultural machinery, in particular to a device for filtering and collecting grass seeds. Background technique [0002] When carrying out ecological grass control, the collection of weed grass seeds and subsequent harmless treatment are very important. As common weeds in wheat and rice fields, weeds such as weed grass and barnyard grass have lignified shells and air pockets on the surface of their grass seeds, which have a super floating ability on the water surface, which is convenient for them to spread to other fields with the help of water flow. In the rice-wheat rotation area, after the wheat is harvested, the rice needs to be plowed, irrigated and soaked in water before the rice is transplanted or directly broadcast. A large amount of straw and weed seeds are mixed together after crops are harvested by returning straw to the field. The traditional method is to manually salvage the straw and...

Problems solved by technology

In the rice-wheat rotation area, after the wheat is harvested, the rice needs to be plowed, irrigated and soaked in water before the rice is transplanted or directly broadcast. A large amount of straw and weed seeds are mixed together after crops are harvested by returning straw to the field. The traditional method is to manually salvage the straw and weed seeds through a net bag and then process them. However, since straw accounts for most of the volume and weight, Not only the labor intensity is high, but also the collection efficiency of grass seeds is extremely low
