Duplex selection machines are relatively popular in China because of their large processing capacity, small footprint, less labor required, and high productivity. It is deeply loved by the majority of seed companies and grain purchasing companies.
The compound selection machine is mainly composed of an elevator, dust removal equipment, air separation part, specific gravity selection part and vibration screening part. Some models can also be equipped with wheat shelling machines, rice awn removers, bag dust collectors and other equipment.
The duplex selection machine has relatively complete functions, so it is relatively complex in structure. The debugging of the specific gravity table is the top priority, and its debugging results directly determine the selected purity of the materials. Now I will give you a brief introduction only on the debugging of the specific gravity table, combined with the characteristics of our company's duplex selection machine specific gravity table.
1 Adjustment of specific gravity typhoon volume
1.1 Adjustment of the air inlet volume of the specific gravity table
This is the air inlet of the specific gravity table. By adjusting the position of the insert plate, the air inlet volume can be adjusted. When processing crops with smaller bulk density, such as sesame and flax, slide the insert plate to the left and the air volume decreases; when processing crops such as corn and soybeans, slide the insert plate to the right and increase the air volume.
1.2 Adjustment of the air leakage volume of the specific gravity station
This is the air vent adjustment handle. If you are processing materials with light bulk density and need a small air volume, slide the handle downwards. The smaller the pointer value, the larger the gap the air vent door opens. The greater the air volume leaked, the smaller the air volume on the specific gravity table. On the contrary, the smaller the leakage air volume, the greater the air volume on the specific gravity table.
The exhaust door is closed, and the air volume on the specific gravity table is larger.
The vent door opens and the specific gravity typhoon volume decreases.
1.3 Adjustment of the air equalization baffle of the specific gravity table
This is the adjustment handle of the wind deflector. When it is found that there are many impurities in the finished product, it means that the wind pressure at the discharge end of the specific gravity table is too high, and the handle needs to be adjusted to the right. The larger the pointer value, the greater the inclination angle of the uniform wind baffle inside the specific gravity table. Wind pressure decreases.
2 Adjustment of specific gravity table impurity removal
This is the impurity removal handle of the specific gravity table. The adjustment principles are as follows:
When the device is just turned on and running, it is recommended that the user adjust the handle to the upper end. The materials are accumulated at the impurity discharge end of the specific gravity table to produce a certain material layer thickness.
The equipment runs for a period of time until the material covers the entire table and has a certain material layer thickness. At this time, gradually lower the handle position to gradually tilt the baffle. When the adjustment is made until there is no good material among the discharged impurities, it is the best baffle position.
To sum up, the adjustment of the specific gravity table of the compound selection machine is nothing more than the adjustment of the air volume and the adjustment of the specific gravity and miscellaneous removal. It seems simple, but in fact it requires users to master it flexibly and use it freely after a period of operation. So to what extent should the specific gravity table be adjusted to the best state? In fact, the answer is very simple, that is, there are no bad seeds in the finished product; there is no good material in the specific gravity; when the equipment is working, the material is in a continuous state on the specific gravity table, which is the best state.
