Agricultural product quality detecting and screening device

Abstract

The invention relates to an agricultural product quality detecting and screening device. The device comprises a screening box, a feeding hopper and a collecting box, a regulating and controlling mechanism and a screening mechanism are arranged on the screening box, the regulating and controlling mechanism comprises a limiting device and a discharging device, and a cleaning device communicating with the discharging device is arranged outside the screening box. The screening mechanism is further composed of a double-selection device and a shaking device in a matched manner, the feeding hopper is arranged at the top of the limiting device, and the collecting box is fixedly installed in the screening box and located below the double-selection device. According to the agricultural product quality detecting and screening device, screening is conducted through a double-layer screening net, impurities of different sizes can be separated conveniently, meanwhile, stacked agricultural products can be pushed and scattered through relative rotation of stirring blades and a screening net, and the situation that the screening efficiency is affected due to stacking is avoided; and meanwhile, a vibration sensing rod in a vibration device regularly pushes the double-layer screening net to shake, the screening efficiency is further improved, and the screening effect of the device is good.

Description

technical field [0001] The invention relates to the technical field of agricultural product detection, in particular to an agricultural product quality detection and screening device. Background technique [0002] Farm produce refers to items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties in various regions. The state stipulates that primary agricultural products refer to plants, animals and their products obtained in agricultural activities, excluding those that have been processed For various processed products, the screening is to use the sieve to make the fine-grained materials smaller than the sieve holes pass through the sieve surface, while the coarse-grained materials larger than the sieve holes stay on the sieve surface, thereby completing the process of separating coarse and fine materials. The separation process can be regarded as composed of two stages: material stratification and fine-grain sieving. Material stratific...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a quality detection and screening device for agricultural products, which has the advantages of being convenient to control the feed crops and having a good screening effect, and solves the problem that the screening device in the prior art cannot control the amount of feed and the The feeding speed is controlled, so that the internal screening effect is affected, and the screening effect is not good.
