[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 A batch feeding device of a wood powder production crusher includes: a frame 1 and a conveyor belt 2. Specifically, a driving roller is provided in the frame 1 for driving the conveyor belt 2 to rotate and transmit, and a power motor for driving the driving roller to rotate is also installed on the frame 1. A baffle is provided on the surface of the conveyor belt 2 for preventing the wood from rolling down during the transmission process. The base frame 3 is arranged on the discharge end side of the frame 1, and a profile frame 4 is installed on the base frame 3, and a tray 5 for receiving the wood is installed on the profile frame 4, so that the wood is lifted to the discharge end by the conveyor belt 2 and falls on the tray 5. A pair of fixed Rod 6, a connecting rod 8 is fixedly installed between the pair of fixed rods 6, and a pair of connecting ears 7 are symmetrically installed at the front end of the pallet 5, the connecting ears 7 are sleeved outside the connecting rod 8, and are rotatably connected to the connecting rod 8, and a cylinder 9 is installed at the tail end of the profile frame 4, and the top of the cylinder 9 is hinged with a support frame 10, which is supported on the lower surface of the tail end of the pallet 5, and the lower end of the cylinder 9 is hinged to the profile frame 4, so that when the cylinder 9 is extended, the bottom end of the pallet 5 is controlled to be raised, so that the wood is discharged from the front end of the pallet 5. During actual operation, the feed port of the crusher is facing the front end of the pallet 5, and the pallet 5 can pour longitudinal wood into the feed port of the crusher.

[0023] A pair of support rods 11 are symmetrically installed at the tail end of the profile frame 4. When the tray 5 is horizontal, the top ends of the support rods 11 contact the bottom surface of the tray 5, thereby improving the stability of supporting the tray 5.

[0024] The left and right sides of the pallet 5 are provided with inclined retaining edges 51 to prevent the wood from rolling down from the left and right sides. A plurality of rollers 52 are rotatably installed inside the pallet 5. The plurality of rollers 52 are evenly arranged in rows along the length direction of the pallet 5, and the length direction of the rollers 52 is parallel to the width direction of the pallet 5. When the pallet 5 is tilted, the rotation of the rollers 52 can help the wood slide down more easily.

[0025] Considering that when the position of the pallet 5 is relatively fixed to the frame 1, the wood will always fall in the same position, which is not conducive to the spreading of the wood on the pallet 5, and less wood can be received. A cylinder 2 12 is also installed on the base frame 3. The cylinder 2 12 is located in the middle of the base frame 3. The output shaft of the cylinder 2 12 is connected to the profile frame 4, thereby driving the profile frame 4 to move. Four sliders 13 are respectively installed at the four corners of the bottom of the profile frame 4, and a pair of parallel straight rails 14 are installed on the base frame 3. The sliders 13 and the straight rails 14 are slidably connected, thereby driving the pallet 5 to move, so that the wood can fall at different positions of the pallet 5. In order to improve the stability of the movement of the pallet 5, a guide rod 15 parallel to the telescopic direction of the cylinder 2 12 is installed on the inner side of the profile frame 4, and a guide sleeve 16 is installed on the middle crossbeam of the base frame 3 corresponding to each guide rod 15, and the guide rod 15 passes through the inside of the guide sleeve 16.

[0026] The discharging end of the frame 1 is connected to an inclined guide plate 18 through a connecting frame 17, so that when the wood falls from the discharging end of the frame 1, it can first fall on the guide plate 18. The guide plate 18 cushions the wood and reduces the impact force of the falling wood on the pallet 5. In order to prevent the guide plate 18 from blocking the pallet 5 from unloading, the cylinder 2 12 is set to drive the pallet 5 to move to the right when it retracts to the shortest position, so that the pallet 5 can be moved away from under the guide plate 18.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
