Multi-purpose maze channel seed screening device

Abstract

The invention discloses a multi-purpose maze channel seed screening device, and belongs to the technical field of agriculture. The multi-purpose maze channel seed screening device solves the problem that seed screening of an existing seed screening device is insufficient. According to the technical scheme, the multi-purpose maze channel seed screening device comprises a vibration mechanism, a seedscreening box, a multistage seed screening mechanism, and maze channels. A maze distributing machine is arranged in the seed screening box below a seed feeding port, and therefore seeds falling fromthe seed feeding port can be dispersed and uniformly distributed and fall, and the seeds are prevented from gathering together and influencing subsequent seed screening operation; in addition, the multistage seed screening mechanism is mounted in the seed screening box, and therefore maze channels distributed in an S shape and communicating in a top and bottom mode are formed in the seed screeningbox, the falling distance of the seeds in the maze channels is increased, and full screening of the seeds is facilitated; the size of screening holes increases step by step, so that withered seeds are screened step by step, and full seeds fall onto the bottom of the seed screening box along the maze channels; and the seed screening box vibrate up and down under driving of the vibration mechanism,and therefore screening, falling and discharging of the seeds in the box can be facilitated.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a multipurpose labyrinth channel seed filter. Background technique [0002] With the rapid development of science and technology, the demand for seed selection operations in agricultural production has also increased. In the process of seed selection, agricultural seed selection machines are used for selection operations. The current agricultural seed selection machines have complex structures and unscientific designs. , the operation process is cumbersome, the volume is large, the space is large, the work performance is unstable, and the work efficiency is not high. This lack of necessary extension of the path of the seed falls leads to a short selection distance, which cannot ensure sufficient selection operations, and affects the later stage. The quality of agricultural breeding and planting. [0003] Chinese patent CN207695160U discloses an agricultural seed selection ...

[0002] With the rapid development of science and technology, the demand for seed selection operations in agricultural production has also increased. In the process of seed selection, agricultural seed selection machines are used for selection operations. The current agricultural seed selection machines have complex structures and unscientific designs. , the operation process is cumbersome, the volume is large, the space is large, the work performance is unstable, and the work efficiency is not high. This lack of necessary extension of the path of the seed falls leads to a short selection distance, which cannot ensure sufficient selection operations, and affects the later stage. The quality of agricultural breeding and planting

[0003] Chinese patent CN207695160U discloses an agricultural seed selection machine device for improving the quality of seed selection, including a fixed side plate, the number of the fixed side plates is two, and the left and right sides of the two fixed side plates correspond to each other. There are two second rotating shafts connected by bearings between the upper ends of the two second rotating shafts, and a transmission belt is arranged between the two second rotating shafts. The first rotating shaft can be driven to rotate by the first motor, and the stirring column and the spiral feeding blade can be driven by the first rotating shaft. Rotate, the seeds can be stirred through the stirring column, the second motor can drive the conveyor belt to rotate, the seeds can be transmitted through the conveyor belt, the dust in the seeds can be filtered through the screen, and the dust in the seeds can be filtered through the exhaust fan. Air pumping, although it can select the best seed quality, but this kind of agricultural seed selection machine can only filter the dust in the seeds, and cannot meet the needs of removing dry seeds, prolonging the seed screening path, and making seed selection more fully. We provide a multi-purpose maze channel seed filter designed to solve the above problems
