Forage choppers are commonly used agricultural machinery in the aquaculture industry. They can be divided into small, medium and large types depending on the size of the machine. Small forage choppers are often referred to as rakes and are mainly used to cut rice straw and wheat straw. They are also used to chop green feed. Large-scale forage choppers are commonly used in cattle farms and are mainly used to cut silage. Therefore, they are often referred to as silage choppers. Medium-sized forage choppers are generally used for both grass and alfalfa silage. The three types of choppers are used as follows: Installation before work: The stationary small forage chopper should be fixed on the foundation or rectangular wood. The distance between the center of the motor and the chopper is 1.2-1.4 meters. Mobile large and medium-sized forage choppers should bury half of the wheels in the soil. The distance between the motor and the center of the chopper is 3 to 6 meters. Check and adjustment prior to use Check that the machine is in good condition, that the screws are loose, and that the lubricant is adequate. Also pay attention to check the cutting gap adjustment, the general small shredder gap is 0.2 ~ 0.4 mm, equivalent to the blade gently from the bottom edge over the scratch, but do not touch the scraping; medium-sized shredder gap is 0.5 to 1 mm, large The shredder gap is 1.5 to 2 mm. Start and work first test by hand, then cut off the clutch, start the motor, idle 3 to 5 minutes until the normal operation, then engage the clutch. If the machine is normal, feed it. It is strictly forbidden to clean and adjust the machine when it is not stopped. Staff should also wear tight sleeves to operate. Maintenance and care: The blade should cut 10000 kilograms of forage every time. It should be sharpened once. The non-greased main bearings shall be washed and replaced once every 4 to 5 months; grease shall be added once every day. The gear and cross-groove couplings in the small shredder should be buttered once every 2 hours. Replace the gearbox lubricant regularly.
