Rapeseed screening machineCommonly used for rapeseed, sesameSelection, grading, and impurity removal of wheat, rice, corn, soybeans, cotton seeds, and various oilseeds. Suitable for large-scale grain growers and feed processing plants.
Rapeseed screening machineScreen 3 tons of soybeans and corn per hour, 2 tons of wheat and rice per hour, and 500-1000 kilograms of cotton and oilseed seeds per hour. The screening rate for impurities such as dust, debris, spoiled grains, and small stones in grains and oilseeds reaches over 95%!
Rapeseed screening machineWorking Principle:
First, place the machine in a horizontal position, turn on the power, start the work switch, and ensure that the motor runs clockwise to indicate that the machine has entered the correct working state. Then pour the screened materials into the feeding hopper, and adjust the stopper plate at the bottom of the hopper correctly according to the particle size of the materials to ensure that the materials evenly enter the upper sieve; At the same time, it also enables the cylindrical fan at the top of the sieve to supply air correctly to the discharge end of the sieve; The air inlet at the lower end of the fan can also be directly connected to a cloth bag to receive light miscellaneous waste from grains.
Rapeseed screening machineThere are four bearings fixed in the channel steel on the frame at the bottom for linear reciprocating motion; The upper coarse sieve of the sieve is used to clean large impurities in the material, while the lower fine sieve is used to clean small impurities in the material.
One side of the selection machine works in coordination with the crankshaft or eccentric wheel driven by the electric motor through a movable connecting rod to complete the entire process of selection and impurity removal.
Rapeseed screening machinestructure
It mainly consists of a screen box, screen frame, screen mesh, vibration motor, vibration damping spring, bracket, sealing cover, etc.
1. Screening box: It is welded from several steel plates of different thicknesses, with certain strength and rigidity, and is one of the main components of the screening machine.
2. Screen frame: made of pine or other wood with minimal deformation, mainly used to maintain the flatness of the screen mesh and achieve normal screening.
3. Screen mesh: There are several types of screens including low-carbon steel, brass, bronze, stainless steel wire, etc.
4. Vibration motor: Generally two copper core three-phase vibration motors are used (see the vibration motor user manual for usage and maintenance methods).
5. Motor pedestal: When installing the vibration motor, the connecting screws must be tightened before use, especially three days before the new screening machine is put into use, and must be repeatedly tightened to avoid loosening and causing accidents.
6. Vibration damping spring: prevents vibration from being transmitted to the ground while supporting the entire weight of the screen box. During installation, the spring must be perpendicular to the ground.
7. Bracket: Composed of four pillars and four channel steels, it supports the sieve box. During installation, the pillars must be perpendicular to the ground, and the channel steels below the pillars should be parallel to each other.
