Three-dimensional composite sieve tray

Abstract

The invention relates to a three-dimensional composite sieve tray. The sieve tray comprises a sieve tray body, material guide nozzles and a driving device; the sieve tray body is of a disc-shaped structure which is uniformly distributed with sieve holes, and a stepping motor is arranged below the sieve tray body; and an upward flanging is arranged on the side edge of the sieve tray, the inner wallof the flanging is an inclined surface, and the conical guide nozzles corresponding to the inner wall of the flanging is correspondingly assembled on the flanging, and multiple limiting columns penetrating through the material guide nozzles extend upwards from the flanging. According to the three-dimensional composite sieve tray, sieve grooves which are inclined upwards and extend to the upper end surface of the sieve tray are arranged so that when the stepping motor is in intermittent rotation, particles can slide on the inclined surfaces of the sieve grooves by inertia, and therefore rotation is realized, and the screening efficiency of the sieve tray is ensured; and the material guide nozzles are arranged, driving blocks are arranged under the material guide nozzles, when the materialguide nozzles rotate along with the sieve tray, the convex surfaces of the bottoms of the driving blocks are stressed upwards to extrude the material guide nozzles so that granular materials in the material guide nozzles can vibrate up and down the accumulation is avoided, and therefore the discharge rate is increased.

Description

technical field [0001] The invention relates to a sieve plate, in particular to a three-dimensional composite sieve plate. Background technique [0002] In the process of receiving or processing agricultural products such as peanuts and rice, screening is inseparable from the sieve plate. Because some crops are mixed with flocs or straw, the conventional sieve plate is affected by the straw when screening, and the sieve holes are blocked. In some cases, the screening efficiency is low and cannot meet the screening requirements. Contents of the invention [0003] In order to solve the above problems and provide a screening device with a simple structure and capable of rapid screening, the present invention designs a three-dimensional composite sieve tray. [0004] The specific technical solution of the present invention is: a three-dimensional composite sieve tray, including a sieve tray, a material guide nozzle and a driving device. The sieve tray is a disc-shaped structu...
