Negative pressure dedusting and rice lifting device with separation function

Abstract

The invention provides a negative pressure dedusting and rice lifting device with a separation function. The negative pressure dedusting and rice lifting device comprises a dedusting box, and a negative pressure wind gap is formed in the upper end of the dedusting box in an interpenetrating manner; a mesh screen is detachably mounted at the opening part of the negative pressure wind gap; a negative pressure lifting pipe is fixedly connected to one side of the dedusting box in an interpenetrating manner; and the other side of the dedusting box is fixedly connected with a drying box. When the negative pressure dedusting and rice lifting device is utilized, the negative pressure lifting pipe is placed on to-be-dried rice, a negative pressure fan is started, the negative pressure fan sucks to-be-dried rice into the dedusting box, small dust and broken rice are sucked out from the negative pressure wind gap, the mesh screen retains rice in the dedusting box, rice falls onto a vibration plate, when a motor rotates, an eccentric rotating wheel eccentrically rotates, a vibration block is driven to slide up and down in a vibration seat, up-down sliding of the vibration plate is converted into up-down vibration through a spring, rice is continually overturned, dedusting is more thorough, and then, rice flows into the drying box from the vibration plate to be dried.

Description

technical field

[0001] The invention relates to the technical field of rice drying, in particular to a negative pressure dedusting rice lifting device with a separation function. Background technique

[0002] At present, with the rapid development of society, the population is increasing, which also means that the demand for food is also increasing. Now with the improvement of food, the yield per mu of food has greatly increased. If it cannot be dried in time processing, there will be insects and rot. The rice dryer uses high temperature to dry the grain, removes the moisture contained in the grain, and achieves the effect of sterilization and drying. The type of feeding device for the rice dryer in the prior art There are many kinds, including screw rod rotating feeding device, direct feeding device and negative pressure lifting feeding device, etc. However, the negative pressure lifting feeding device is easy to bring in a large amount of dust during use, and the dust cann...
