Multifunctional seed metering device

Abstract

The invention discloses a multifunctional seed metering device. The multifunctional seed metering device comprises a cover, a funnel, a grain inlet, a base and a control box; the cover is arranged above the base; the control box and the funnel are both arranged on the cover; a transverse plate bracket is arranged on the top surface of the base; the grain inlet penetrates through the transverse plate bracket, the top end is connected with the funnel, and the bottom end extends into the base; a first guide plate, a conveying device, a second guide plate, a counter, a collecting box and an electronic scale are arranged in the base; the conveying device is connected with the transverse plate bracket; the first guide plate consists of two L-shaped plates; bottom transverse plates are arranged on the conveying device; upper vertical plates form a circular table type cavity structure sleeved with the grain inlet; limiting grooves are respectively formed in the lower surfaces of the two bottom transverse plates; the second guide plate is a funnel-shaped structure for covering the outer periphery of the conveying device, the top end is connected with the transverse plate bracket, and the bottom end is connected with the counter; the collecting box and the electronic scale are arranged on the base below the counter; and the control box is respectively connected with the conveying device, the counter and the electronic scale. The multifunctional seed metering device is simple in structure, convenient to operate and precise in counting.

Description

technical field [0001] The invention relates to a thousand-grain seed counting and weighing device, in particular to a multifunctional seed counting device. Background technique [0002] The counting and weighing of seeds is an indispensable step in the process of crop research in agricultural colleges and research institutes. For major food crops such as rice, wheat, corn, etc., measuring the thousand-grain weight is an important method for judging the size and fullness of seeds. Index is the content of testing seed quality and crop testing, and it is also an important basis for predicting yield in the field. [0003] The existing thousand-grain weight counting method of seeds generally takes the form of a counting board or directly counts manually. The counting board is generally a prepared template and can only count seeds of a specified size. Different counting boards need to be replaced when counting different seeds. When there are many types of seeds, it is more cumbe...

[0003] The existing thousand-grain weight counting method of seeds generally takes the form of a counting board or directly counts manually. The counting board is generally a prepared template and can only count seeds of a specified size. Different counting boards need to be replaced when counting different seeds. When there are many types of seeds, it is more cumbersome, and the counting board has the defect that it is easy to get stuck

However, when manual counting is adopted, a lot of precious time of the staff is wasted, and there is a problem of measurement accuracy
