[0014] The present invention provides a grinding device for biomass fuel processing, which has the following beneficial effects: (1) In the present invention, the motor is started, which drives the output end of the motor to rotate. The rotation of the output end of the motor drives the grinding disc to rotate. The rotation of the grinding disc drives the raw material to move. The raw material moves to between the grinding disc and the fixed disc, and the raw material is ground by the grinding disc and the fixed disc. The rotation of the grinding disc drives the scraper to rotate. The rotation of the scraper pushes out the processed raw material and cleans the biomass fuel powder. At the same time, the scraper rotates and contacts the cleaning rod. The scraper continues to rotate and drives the cleaning rod to move. The movement of the cleaning rod drives the short rod to move. The movement of the short rod drives the rotating shaft to rotate, so that the cleaning rod cleans the scraper surface to prevent the device from mixing with the residual biomass fuel powder when it needs to process biomass fuels of different materials in the future, thereby affecting the performance of the finished product.

[0015] (2) In the invention, the contact between the scraper and the inclined block drives the inclined block and thus drives the round rod to move. The movement of the round rod drives the extrusion plate to move to squeeze the liquid inside the No. 1 hydraulic cylinder. The squeezed liquid enters the No. 2 hydraulic cylinder through the round hole between the No. 1 hydraulic cylinder and the No. 2 hydraulic cylinder. The liquid enters the No. 2 hydraulic cylinder and causes the lifting plate to move upward, driving the vertical rod upward. The vertical rod moves upward, driving the moving plate upward, thereby driving the slider upward. The slider moves upward, driving the connecting rod upward, thereby causing the connecting rod to rotate. The rotation of the connecting rod drives the long plate to move. The movement of the long plate allows the raw materials in the feed port to enter the main body, thereby realizing intermittent feeding and preventing excessive one-time feeding from causing raw material blockage, thereby reducing work efficiency. At the same time, when there is too much raw material in the guide pipe, the feed port is closed to prevent continued feeding from causing the guide pipe to be blocked by raw materials, thereby reducing work efficiency.

[0016] (3) In the present invention, when the scraper rotates to push the processed raw materials into the discharge port, the processed raw materials fall into the discharge pipe through the square tube, and at the same time, the scraper rotates and contacts the moving rod. The scraper continues to rotate to move the moving rod, and the moving rod moves and contacts the lifting rod. The moving rod continues to move to move the lifting rod downward. The lifting rod moves downward to drive the discharge pipe to move. The movement of the discharge pipe drives the fixed plate to move. The movement of the fixed plate drives the rotating plate to move. The rotating plate moves and contacts the bent rod. The rotating plate continues to move to cause the bent rod to rotate. When the rotating plate continues to move until it is no longer in contact with the bent rod, the bent rod is affected by the elastic force of the No. 3 spring sheet and rotates toward the discharge pipe, causing the bent rod to knock on the discharge pipe to prevent the biomass fuel powder from sticking to the inside of the discharge pipe. At the same time, the discharge is achieved by making the discharge pipe move up and down. BRIEF DESCRIPTION OF THE DRAWINGS
