Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grain processing, especially relates to a high -efficient vibrating screen separator for selection. BACKGROUND

[0002] In the grain processing industry, screening operation is a very key process, which aims at removing impurities, particles not meeting processing requirements and preliminarily classifying and screening the grain, so as to provide high-quality, uniform-specification raw materials for subsequent processing procedures, so as to ensure the quality and safety of the final grain product, however, the structure of the traditional screening machine is static screening, the screening efficiency is extremely low, a large amount of manpower and time are consumed, and the grain is prone to accumulation in the screening process, so that the screening effect is poor, therefore, we launch a high -efficient vibrating screen separator for selection. SUMMARY

[0003] The main purpose of the utility model is to provide a high -efficient vibrating screen separator for selection, which can effectively solve the problems in the background art.

[0004] To achieve the above object, the technical scheme adopted by the utility model is:

[0005] A high -efficient vibrating screen separator for selection, comprising a base, both ends of the base are fixedly connected with two fixed blocks, the upper end of the four fixed blocks is provided with a fixed hole passing through up and down, the upper end of the base is provided with a placing groove, the collecting box is movably sleeved in the placing groove, the left vibration mechanism is fixedly installed on the upper end left part of the base, the right vibration mechanism is fixedly installed on the upper end right part of the base, the left vibration mechanism and the right vibration mechanism are the same structure and are distributed in left and right mirror image, the screening assembly is fixedly connected between the left vibration mechanism and the right vibration mechanism.

[0006] The left vibration mechanism comprises a vibration motor, the output end of the vibration motor is fixedly installed with a sensing head, the outer surface right part of the sensing head is fixedly connected with a fixed plate, the right end of the fixed plate is fixedly connected with a mounting block, the mounting block is connected with a connecting assembly, and the lower end of the vibration motor is fixedly connected with the upper end of the base.

[0007] Preferably, the connecting assembly comprises a bottom block, the upper end of the bottom block is fixedly connected with a stable rod and a spring, the upper end of the stable rod is fixedly connected with a top block, and the lower end of the bottom block is fixedly connected with the upper end of the base.

[0008] By adopting the above technical scheme: through the cooperation of the spring and the stable rod, the connecting assembly can effectively reduce the irregular shaking and deviation in the vibration process.

[0009] Preferably, the upper end of the stabilizing rod is movably connected with the lower end of the mounting block, and the upper end of the spring is fixedly connected with the lower end of the mounting block.

[0010] By using the above technical scheme, the upper end of the stabilizing rod is movably connected with the lower end of the mounting block, so that a precise guiding path is provided for the mounting block during vibration, and when the vibration motor works to generate a vibration force, the mounting block can only move up and down along the axial direction of the stabilizing rod, thereby effectively limiting displacement in the horizontal direction and other unnecessary directions.

[0011] Preferably, the stabilizing rod is located in the spring and has a gap with the inner wall surface of the spring.

[0012] By using the above technical scheme, when the equipment is running, the spring will be deformed by stretching and contracting along with the vibration of the mounting block, and if the stabilizing rod is closely attached to the spring, a large friction force will be generated, which not only consumes additional energy and reduces the running efficiency of the equipment, but also causes the spring and the stabilizing rod to be severely worn.

[0013] Preferably, the screening assembly comprises a screening frame and a clamping plate, the left end and the right end of the screening frame are provided with clamping grooves, the inner wall surface of the screening frame is embedded with a screening net at the lower part, and two clamping plates are arranged, and the outer side surfaces of the two screening frames are respectively fixedly connected with the outer surfaces of the corresponding mounting blocks.

[0014] By using the above technical scheme, the connection mode of the screening frame and the mounting block through the clamping plate is extremely convenient and efficient. During the assembly of the equipment, only the two clamping plates need to be aligned with the clamping grooves at the two ends of the screening frame and pushed in gently, so that the quick fixed connection of the screening frame and the mounting block can be realized.

[0015] Preferably, the inner side surfaces of the two clamping plates are movably clamped in the corresponding two clamping grooves.

[0016] By using the above technical scheme, when the screening frame needs to be maintained, cleaned or replaced, the disassembly is relatively simple, and only a small external force needs to be applied to pull out the clamping plate from the clamping groove, so that the screening frame can be easily taken out.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. In the utility model, the screening net in the screening assembly can be customized according to the particle size requirement of different grains, and can accurately separate the impurities, broken particles and complete full particles in the grain, ensure the purity and quality of the processing raw materials, improve the quality stability of the subsequent processing products, reduce the wear and failure of the processing equipment caused by impurities, the screening assembly is connected movably through the clamping plate and the clamping groove, so that the screening frame is extremely convenient to install and disassemble, when the grain processing variety is switched or the screening net needs to be cleaned and replaced regularly, the operator can quickly complete the operation, reduce the equipment maintenance time and labor cost, and improve the adaptability and flexibility of the equipment in different grain processing scenes.

[0019] 2. In the utility model, the left vibration mechanism and the right vibration mechanism work cooperatively to generate stable and uniform vibration frequency and amplitude, so that the grain presents a good fluidization state in the screening frame, accelerates the screening process, compared with the traditional static screening equipment, the screening efficiency is significantly improved, can meet the demand of large-scale grain processing production, effectively shorten the processing cycle and improve the production capacity.
