Potatoes are a very common food on the table all over the world. Due to the variety, shape, and size, potatoes have different ** and uses. Therefore, for the economic value of the crop, growers usually classify potatoes by size to meet different market needs. Traditional sorting of potatoes by size is often done by hand, which is not only inefficient but also costly. Manually sorting potatoes based on feeling is also not accurate enough. The potato screening machine manufactured can overcome these shortcomings and can be described as a potato screening artifact in the new era.
The potato screening machine is a vibrating screening equipment that relies on a vibrating motor to provide power and a stainless steel sieve hole to precisely control the specifications of the sorted potatoes. The equipment has high efficiency, high precision, multiple classifications, no damage to potatoes, many functions and easy operation. Multi-point sorting, potato sorting efficiency is 300% of the traditional manual sorting efficiency, and the cost is only 1 10 of the labor cost. In addition, the equipment can be used not only for sorting potatoes (up to 6 varieties at a time), but also for sorting and removing dirt from almost all other crops. It has been widely used in sesame, soybean, garlic, mushroom, millet, jujube and other crops.
1。The potato screening machine can be customized in style and size according to needs, can be adapted to the feeder, and can be equipped with a fan;
2。The grading accuracy is high, the processing capacity is large, and the single grain sorting capacity can reach more than 10 tons;
3。At the same time, beans, jujubes, wheat, corn, peanuts, sorghum, millet and other crops can be decontaminated and sorted. One machine is multi-purpose, and the whole machine has great investment value;
4。The machine adopts a new mesh structure, and the effective screen area of the same model is increased by 30%, making it easier and more efficient to change the screen;
5。The equipment has low energy consumption, good sealing performance, no overflow of mixed liquid level, and long service life.
How the potato screening machine works.
The potato sieve is powered by a double vibrating motor. When two vibrating motors rotate synchronously in opposite directions, the excitation force generated by their eccentric blocks cancels each other out in the direction parallel to the axis of the motor and is superimposed into a resultant force perpendicular to the direction of the axis of the motor. Therefore, the trajectory of the net machine is a straight line. The two motor shafts have an angle of inclination in the vertical direction relative to the surface of the screen. Under the combined force of excitation force and material gravity, the material is thrown up and jumps or moves forward in a straight line on the screen surface, so as to achieve the purpose of screening and sorting the material. 。
It is suitable for sieving particle size 0074-5mm, moisture content less than 7%, non-sticky all kinds of dry powder or granular materials. The material enters the sorter inlet evenly from the feeder. When the vibrating motor is excited, the material jumps towards the outlet and is shielded. A small number of products and unqualified products are sorted by multi-layer screening. The top and bottom of the sieve are discharged from their respective outlets and flow into the silo or hopper.
Introduction to the structure of potato screening machine The sieve machine is mainly composed of a sieve box, a sieve frame, a sieve, a vibrating motor, a motor base, a vibration damping spring, a bracket, etc.
1。Network box: It is welded by several steel plates of different thicknesses, which have a certain strength and rigidity. It is the main part of the network machine.
2。Screen frame: made of pine or wood, with small deformation, mainly used to keep the screen flat and achieve normal shielding.
3。Mesh: There are various types of mesh, such as mild steel, brass, bronze, stainless steel wire, etc.
4。Vibrating motor (see vibrating motor user manual for details for use and maintenance).
5。Motor base: Install a vibrating motor. The connecting screws must be tightened before use. Especially three days before the trial of the newly bought net machine, it must be tightened repeatedly to avoid accidents caused by loosening.
6。Shock absorbing springs: prevent vibrations from being transmitted to the ground and support the full weight of the screen box. When installed, the springs must be perpendicular to the ground.
7。Bracket: It is composed of four columns and two channel steels to support the screen body. When installing, the column must be perpendicular to the ground, and the channel steel under the two columns should be parallel to each other.
Potato Screening Machine Routine Maintenance Guide.
1。Before starting the machine, all guards should be returned to their original positions and all personnel should stand in a safe place.
2。The machine can only be started after all the protective plates have been installed. Do not stand on vibrating parts when using the screen.
3。Before starting work, the drive motor should be isolated.
4。Equipment isolation: The screen must be insulated before removing the protective piece or before starting any other work or before anyone climbs on or under the screen to work.
5。Electrical installation should be carried out by experienced personnel.
6。If the linear vibrating screen is an inclined vibrating screen, a protective device is installed at the lower part of the screen body. During the test run, the vibrating screen must stop at the end of the transmission direction (relative to the motor end). The isolation device isolates the operator from the vibration source.
7。During the operation of the vibrating screen, it is strictly forbidden to open the middle protective net of the gearbox and the protective net of the final gearbox.
8。During the working process of the vibrating screen, when the observation hole of the sieve body is opened, protective measures must be taken to avoid material splashing and hurting the eyes.
9。When the vibrating screen is working, do not touch the sealing layer to avoid pinching your fingers.
10。The elastic force of the springs on both sides of the screen body should be synchronized, otherwise the shielding efficiency will be reduced due to uneven vibration of the screen body. If an abnormal vibration pattern is found, stop the vehicle for repair immediately.
11。The shaker should be checked after half an hour of parking and after the temperature has dropped to ambient temperature.
