Use skill and maintenance of straw crusher machine

Common Straw crushers machines include corn stalk shredder, Tree branch shredder, peanut shell shredder, and so on. It is a material crushing equipment in organic fertilizer processing and production technology and feed processing technology. Moreover, the Straw crusher machine has a high utilization rate in various fields. For example, in fertilizer processing, the Straw crusher is used in the early stage of livestock manure treatment, straw, fungus residue, and other auxiliary materials. The utilization rate is high. If you want to extend the use time of the machine, you must do well in its use and maintenance. The following are some straw shredder use skills and maintenance summarized by Shenghong Heavy Industries.

 

Straw crusher machine installation and use:

1. The Straw crusher machine should be fixed on the ground, it can be fixed with cement. If the working place is often changed, the crusher and the motor should be installed on the frame made of Angle steel.
2. After installation, you should carefully check whether the installation is in place, and check whether the installation is not firm enough. Whether the motor shaft and the shredder shaft are parallel, and at the same time check whether the transmission belt tightness is appropriate.
3. Before starting the Straw Crusher, the rotor is first rotated by hand to check whether the operation is flexible and normal, whether there is a collision in the casing, whether the rotation direction of the rotor is correct, and whether the motor and crusher are well lubricated, etc.
4. Don’t change the pulley frequently to prevent the speed from being too high or too low.
5. After starting, it should be idling for 2 to 3 minutes, and then feeding work after there is no abnormal phenomenon.
6. The material of the Straw crusher should be uniform. If there are any phenomena such as noise, high temperature of bearing, and body, or external spraying, it should be stopped immediately for inspection and troubleshooting.
7. Before work, the staff should carefully check the materials to prevent metals, stones, and other hard objects from entering the crushing chamber and causing accidents.
8. During feeding, staff should stand on the side of Straw Crusher to avoid being injured by the bouncing debris. Do not crush long stems with your hands too tightly to prevent them from being carried in.
9. Stop feeding before shutting down, and cut off the power to shut down after the materials in the standby are removed. Cleaning and maintenance should be carried out after shutdown.
10. After 300 hours of operation of the Straw crusher machine, the bearings must be cleaned and the oil must be replaced; when installing the oil, it is better to fill the gap of the bearing seat with 1/3, not more than 1/2. When the machine is stopped for a long time, the transmission belt should be removed.

Straw crusher machine maintenance and maintenance:

1. Regularly check the power supply of the Straw crusher machine, check the power socket, plug, and power cord for oxygen loss or breakage.
2. Regularly check whether the lubrication of the bearing is in good condition, and regularly use lubricating oil for maintenance.
3. Regularly check whether all fasteners are fastened, and if there is any looseness, deal with it in time.
4. Regularly check whether the transmission belt is installed correctly and in good condition. If the belt is found to be damaged, it should be replaced in time. When there is oil on the belt or sheave, wipe it off with a clean rag in time.
5. Regularly check whether the protective device of the straw crusher is in good condition. If the protective device is found to be unsafe, it should be eliminated in time.
6. Regularly check whether there are materials or other sundries in the damaged cavity if sometimes it should be cleaned up.
7. Regularly check whether the head of the Straw crusher machine hydraulic jacking machine or the jacking screw is retracted and whether the adjusting shim is installed correctly and pressed tightly.
8. Regularly check the sealing condition of the fan to prevent the sand and soil from causing serious abrasion on the wind machine, causing the impeller body and the rivet head of the hub to fall off, and fatigue cracks at the rivet hole.
9. If the rivet head of the impeller of the straw crusher is worn, the worn rivet head can be returned to the original normal state by pressing the impeller body and the hub with electric welding surfacing.
10. If fatigue cracks are prone to occur at the rivet holes of the Straw crusher machine, a whole unused new welding rod can be used to repair the cracks, but it should be done symmetrically around the axis of the impeller, and the cracks should be repaired. Leave the welding rod there, and then use a new welding rod to repair the symmetrical rivet hole cracks. The electrode left after welding is the same length as the electrode left after repairing the symmetrical rivet to ensure that the weight of the welding is equal. If there is no crack at the symmetrical rivet hole, the welding rod should be surfacing here to offset the welding weight of the newly repaired crack at the symmetrical rivet hole. Welding can repair cracks in accordance with this method of symmetrical weight compensation.
11. A simple dynamic balance test is carried out on the impeller, and the method is very simple. Prop up the impeller with hand to make it gently rotating, can not reach the balance of the place will stop to the low point and swing around. If there is a heavy spot welding on the opposite impeller, increase the weight to balance it, or use an Angle grinder to grind the welding mark of the heavy impeller, also can achieve balance, so that the fan can be repaired for normal work. Note that in the process of repairing the fan, electric welding can not be used to spot welding at will, and the welding mark is left on the impeller, so as not to affect the balance of the fan impeller, fail to reach the purpose of repair, and cause greater losses.
