Use and maintenance of straw returning machine

straw returning can increase the content of soil organic matter, improve soil fertility, and promote the continuous production and income of crops. As an application machine, the straw returning machine should pay attention to the following problems in use:

before operation, carefully check whether the connection of various parts is reliable, whether the fasteners are loose, and whether the rotating parts are flexible. Check the tool holder and blade one by one. If deformation, damage or shortage is found, it shall be repaired, replaced and supplemented in time. Check and adjust the tension of the V-belt, and add lubricating oil and grease as required. At the same time, after being properly connected, the empty billet and downstream finished product shall bounce back or the scrap shall be assisted to run for 3-5 minutes, and the operation can be started only after confirming that all parts operate normally

during operation, after the unit enters the ground, the tractor's suspension rod should be adjusted first to keep the front, rear, left and right of the machine horizontal, and pay attention to adjusting the height of the depth limiting wheel to maintain a reasonable stubble height and prevent the blade from entering the soil. Different operation speeds shall be adopted according to the density and growth of crops, soil moisture content and firmness, and the tension of the drive belt shall be observed at any time. If it is too loose or too tight, it shall be adjusted in time. When the power take-off shaft is connected, the unit shall be unloaded at low speed. After the engine accelerates to the rated speed, the unit can start slowly and put into load operation. It is strictly prohibited to start the field returning machine and the machine with load. Analysis: the development status and trend of flame retardant materials improve the support capacity of new materials throughout the whole process. The broach is manually started to avoid damage to the machine parts, and it is not allowed to turn or reverse with load. When the unit is away from the transferred land, The power shall be cut off. It is strictly prohibited for non damage personnel to approach the operating unit or track behind the unit to ensure personal safety

after the operation,

it is necessary to timely remove the deposits at the rotating parts and the dirt layer on the inner wall of the guard plate, and inspect the fasteners of all rotating parts for timely adjustment and replacement. Fill each lubricator with grease. When not in use for a long time, the exposed parts shall also be treated for rust prevention. The blades shall be coated with oil and kept. The machine shall be stored in a dry, ventilated and transparent warehouse. If it is stored in the open air, rain proof and sun protection facilities shall be added

common faults and troubleshooting

poor grinding quality

the main reason is that the drive belt is too loose; If the blade is worn or short, the forward speed is too fast, the load is too heavy, the blade is reversed, etc., it shall be replaced or adjusted according to the actual inspection

the feeding inlet is blocked

because the crops are too dense or the forward speed is too fast. Reducing the number of operation lines or the operation speed can eliminate the fault

the strong vibration of the machine

may be caused by blade falling off, loose fastening bolts, wrong installation of universal joint fork, bearing damage, etc., which should be eliminated according to the inspection results

the transmission belt is severely worn

the reasons are improper belt tension, different lengths, excessive load or blade digging, etc., which should be adjusted according to the actual inspection
