As a big agricultural country, China produces a lot of crop straws every year in the busy farming season. These straws are usually piled up or discarded at will, which not only affects the appearance of rural villages, but also pollutes people’s living environment after being stored outdoors for a long time.

In the past, in order to deal with the crop straws, people would choose to burn them directly in farmland, but this would cause air pollution, which is not in line with the concept of sustainable development. Actually, crop straw has its potential utilization value. Small straw, in fact, contains high economic value, feeding value, fuel value and fertilizer value, which has not been discovered and utilized by people. To develop and utilize these potential values of straw, we need to thoroughly understand how to excavate these values. Straw is used as feed to excavate its nutritional value, and after processing by some equipment, feed suitable for specific species can be produced according to different requirements of different breeders on feed size, hardness, etc. When it is used as fertilizer, it is the fertilizer efficiency value of straw that is exploited and utilized. After a certain amount of treatment, it is converted into fertilizer with high fertilizer and used in various planting operations. So today, straw briquette machine is more and more popular. Straw briquette machine is a device that crushes and compresses biomass materials such as straw to make efficient and environmentally friendly fuel or feed. The products extruded by straw briquette machine are used as feed or fuel. Through practice and continuous improvement, the straw briquette machine has been improved day by day. Straw briquette machine has the advantages of high automation, high output, low price, low power consumption, simple operation and no environmental pollution. Therefore, the straw briquette machine can be widely used to press various biomass raw materials such as crop straws and twigs.

When using straw briquette machine, regular maintenance can prolong the service life of the machine and create greater economic value.

1. After the straw briquette machine equipment is used every day, clean up the residues.

2. Check the screws: regularly check whether the screws at the connecting parts of the motor and transmission parts of the briquetting machine are loose, so as to tighten them in time.

3. Check the wear condition of vulnerable parts. The seriously worn parts should be updated in time. Check the bearings of various parts, and carry out cleaning and regular maintenance.

4. Lubricate the shaft oil; Fill the oil hole of the roller wheel once a day (at the top of the eccentric shaft), and fill the vertical shaft seat once a week. The butter used is high-temperature resistant lithium-based grease.

5. Density adjustment: The density of the finished briquette can be adjusted by adjusting the gap between the pressing wheel and the die, and the gap between 1.5~2.5mm and 2.5 mm is the optimal co-operation state of the main engine. When the gap between the die and the pressing wheel exceeds 5mm, the output of the equipment will be seriously affected, and the phenomenon of machine swallowing will also occur.

The method of adjusting clearance is as follows:

Loosen the round nut with a hook wrench, remove the connecting plate of the pinch roller, loosen the locking screw for clamping the eccentric shaft in the scraper with an internal hexagonal wrench, and then rotate the flat shaft at the head of the eccentric shaft with a wrench to make the eccentric part of the eccentric shaft rotate outward, so as to adjust the gap between the pinch roller and the die. Adjust the other pinch roller in the same way (it is required that the upper and lower clearances between the two rollers and the I-shaped die mouth are consistent, and the height of the two rims is consistent). After the clearance is adjusted in place, tighten the locking screw, reset the connecting plate, and lock the round nut.

Only if there is no problem with the equipment, the normal production will not be delayed. Therefore, it is necessary to maintain the machine regularly according to the above requirements.
