Seed screening equipment

Abstract

The invention provides seed screening equipment which comprises a feeding hopper, a screening box body, a liquid separating cylinder and a control cabinet. The bottom of the feeding hopper is connected with a screening cylinder through a connecting pipe, and the screening cylinder is located inside the screening box body; the liquid separating cylinder is arranged under the screening box body, a wizened seed filter cavity is formed in the outer side of the top of the liquid separating cylinder, the interior of the liquid separating cylinder is fixedly connected with a second motor through a first connecting rod, and a bottom discharging outlet of the liquid separating cylinder is provided with a valve; a conveying belt is arranged below the valve, a water trough is arranged below the conveying belt, and a plurality of water holes are formed in the surface of the conveying belt; a water tank is arranged on one side of the liquid separating cylinder, and the liquid separating cylinder and one side of the water tank stretch into the water trough through water pipes and water pumps correspondingly; and a drying box is arranged below the tail end of the conveying belt. According to theseed screening equipment, automatic processing of seeds is achieved, resources are reasonably utilized, the cost is reduced, and the seed quality is improved.

Description

Technical field: [0001] The invention relates to the technical field of seed screening, in particular to a seed screening device. Background technique: [0002] The seed itself is the basis for the development of agricultural business, and excellent seeds play a vital role in the final harvest. After being damaged, the nutrients shown inside the seeds show a lack of different properties, which also affects the emergence rate and seedling growth status. Moreover, the seeds contain fine sand and some unfulfilled or shriveled seeds. If these bad seeds and impurities are not screened out in advance, the germination rate of the seeds will be greatly affected. The traditional seed selection method is mostly carried out manually, which is time-consuming and laborious, and it cannot guarantee that the impurities and shriveled seeds in the seeds can be fully selected. In addition, the seeds need to be cleaned and dried before packaging. This process is independent of the sieving pr...

Problems solved by technology

Moreover, the seeds contain fine sand and some unfulfilled or shriveled seeds. If these bad seeds and impurities are not screened out in advance, the germination rate of the seeds will be greatly affected.

The traditional seed selection method is mostly carried out manually, which is time-consuming and laborious, and it cannot guarantee that the impurities and shriveled seeds in the seeds can be fully selected

In addition, the seeds need to be cleaned and dried before packaging. This process is independent of the screening process. Due to the need for a certain transfer time in the process, the processing cycle of the seeds is prolonged and the processing efficiency of the seeds is reduced.
