Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biomass particle production, in particular to a wood crusher for processing biomass particles. Background Art
[0002] The wood crushing and drying device for biomass pellet processing first performs preliminary mechanical crushing on the waste generated by the factory's production of wooden pallets to make it smaller blocks or strips. The materials that have undergone preliminary crushing will then be further crushed. At this stage, the wood will be further crushed into finer particles or powder. The crushed powder will then be transported to the drying equipment for drying through a conveying device. The dried material can then be used to prepare biomass pellets.
[0003] The existing crusher uses crawler tracks to transport wood raw materials into the body for crushing. Since the wood waste in the production process is loaded inside the transfer frame, if it is directly dumped, most of the wood waste of varying sizes will scatter to the ground from both sides of the crawler tracks. Therefore, workers are required to use tools such as shovels to transfer the wood from the transfer frame to the crawler tracks little by little, resulting in low loading efficiency.

[0014] The utility model is further configured as follows: a linkage rod is arranged between the two pulling wheels.
[0015] The beneficial effects of the utility model are:
[0016] 1. By setting a bucket-shaped loading frame and a third loading plate that can be rotated and opened, when it is necessary to transfer the wood waste from the transfer frame to the conveyor belt of the crusher, the worker only needs to rotate the third loading plate through the driving mechanism to open the third loading plate outward, and then use a forklift or other tools to lift the transfer frame to the third loading plate for dumping, and then drive the third loading plate to rotate upward and close. Since the loading frame is a bucket-shaped frame that is wide at the top and narrow at the bottom, the wood will not fall from both sides of the conveyor belt, but will stay in the loading frame. Subsequently, the wood in the loading frame is transported little by little into the machine body through the feeding gap by the running conveyor belt for crushing. Therefore, the loading process of the wood waste in the transfer frame can be completed at one time, and there is no need for workers to use shovels and other tools to load the wood little by little, which greatly improves the loading efficiency.
[0017] 2. By setting the first limit block, the second limit block and the positioning hole, when the third loading plate needs to be opened, it is only necessary to pull the second limit block outward so that the positioning rod slides along the rotating handle until the first limit block abuts against the rotating handle. At this time, the first limit block is separated from the positioning hole, and the pulling wheel can be rotated to make the third loading plate open outward until the third loading plate abuts against the supporting block; when the transfer of wood waste is completed and the third loading plate needs to be closed, the rotating handle is rotated, and the two pulling wheels are driven to rotate synchronously through the linkage rod, and the third loading plate is pulled to rotate upward until the third loading plate abuts against the first loading plate. At this time, the first limit block is just aligned with the positioning hole, so the second limit block is pushed so that the second limit block abuts against the rotating handle, and the first limit block is just engaged with the positioning hole, so as to fix the rotating handle, and then fix the position of the third loading plate; making the opening and closing of the third loading plate simple and convenient.
[0018] 3. By setting up movable grooves, baffle plates, etc., after the third loading plate rotates outward, workers manually pull the baffle plates on both sides to rotate outward until the baffle plates hit the third loading plate. The two sides of the third loading plate are shielded by the baffle plates to prevent the wood waste from falling from the two sides of the opened third loading plate when dumping the wood waste in the transfer frame, thereby ensuring that the wood waste is completely transferred into the loading frame.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] The utility model provides a wood crusher for processing biomass particles, such as Figures 1 to 3 As shown, it includes a machine body 1, a conveying roller 2 rotatably arranged on the machine body 1, a conveying belt 3 arranged on the conveying roller 2, and a bucket-shaped loading frame 4 arranged on the machine body 1, the bottom opening of the loading frame 4 is located directly above the conveying belt 3, the loading frame 4 includes a first loading plate 4a relatively inclinedly arranged on both sides of the machine body 1, a second loading plate 4b inclinedly arranged on one side of the two first loading plates 4a, and a third loading plate 4c rotatably arranged on the other side of the two first loading plates 4a, a feeding gap is arranged between the bottom of the second loading plate 4b and the conveying belt 3, and the first loading plate 4a is provided with a driving mechanism 5 for driving the third loading plate 4c to rotate.
[0026] Furthermore, the driving mechanism 5 includes a positioning plate 5a arranged at the top of the first loading plate 4a in the vertical direction, a pulling wheel 5b rotatably arranged on the positioning plate 5a, and a pull rope 5c arranged on the pulling wheel 5b, one end of the pull rope 5c away from the pulling wheel 5b is fixedly connected to the top of the third loading plate 4c, a rotating handle 6 is arranged at one end of the pulling wheel 5b, and a fixing part 7 for fixing the rotating handle 6 is arranged on the positioning plate 5a.
[0027] Furthermore, the fixing member 7 includes a positioning hole 7a opened on the first loading plate 4a and a positioning rod 7b slidably arranged at the end of the rotating handle 6 along the horizontal direction, and one end of the positioning rod 7b can be engaged with the positioning hole 7a.
[0028] Furthermore, a first limit block 8 is provided at one end of the positioning rod 7b close to the positioning plate 5a, and the first limit block 8 can be movably fitted to the inner wall of the positioning hole 7a. When the first limit block 8 contacts the rotating handle 6, there is a set distance between the first limit block 8 and the positioning plate 5a.
[0029] Furthermore, a second limit block 9 is provided at one end of the positioning rod 7b away from the positioning plate 5a. When the second limit block 9 abuts against the side of the rotating handle 6 away from the positioning plate 5a, the first limit block 8 engages with the positioning hole 7a.
[0030] Furthermore, a support frame 10 is disposed on one side of the machine body 1 close to the third loading plate 4 c , and a support block 11 is disposed on the support frame 10 , and the third loading plate 4 c can abut against the support block 11 .
[0031] Furthermore, a movable groove 12 is opened in the middle of the first loading plate 4a, and a baffle plate 13 is movably arranged in the movable groove 12 and is rotatably connected to the bottom of the first loading plate 4a. When the third loading plate 4c abuts against the support block 11, the baffle plate 13 can be rotated to abut against the third loading plate 4c.
[0032] Furthermore, a first elastic block 14 is disposed at the bottom of the first loading plate 4 a , and the bottom of the first elastic block 14 is movably fitted to the conveyor belt 3 .
[0033] Furthermore, a second elastic block 15 is provided at the bottom of the third loading plate 4 c , and the bottom of the second elastic block 15 is movably fitted to the conveyor belt 3 .
[0034] Furthermore, a linkage rod 16 is provided between the two pulling wheels 5b.
[0035] When it is necessary to transfer the wood waste from the transfer frame to the conveyor belt 3 of the crusher, the worker first pulls the second limit block 9 outward, so that the positioning rod 7b slides along the rotating handle 6 until the first limit block 8 abuts against the rotating handle 6. At this time, the first limit block 8 is separated from the positioning hole 7a, and the pulling wheel 5b can be rotated to make the third loading plate 4c open outward until the third loading plate 4c abuts against the supporting block 11. After the third loading plate 4c is rotated outward and opened, the worker manually pulls the baffle plates 13 on both sides to rotate outward until the baffle plates 13 abut against the third loading plate 4c, and then uses a forklift or other tools to lift the transfer frame to the third loading plate 4c for dumping. After the wood waste is transferred to the loading frame 4, the worker turns the rotating handle 6 on one side, and simultaneously pulls the two pulling wheels 5b and the pull rope 5c through the linkage rod 16 to rotate, so that the third loading plate 4c rotates upward Closing, during this process, the third loading plate 4c will push the baffle plate 13 to rotate upward with the third loading plate 4c and enter the moving groove 12; since the loading frame 4 is a bucket shape that is wide at the top and narrow at the bottom, the wood will not fall from the two sides of the conveyor belt 3, but will stay in the loading frame 4. Subsequently, the wood in the loading frame 4 will be transported to the machine body 1 through the feeding gap little by little by the running conveyor belt 3 for crushing. Therefore, the loading process of the wood waste in the transfer frame can be completed at one time, and workers do not need to use tools such as shovels to load the wood little by little, which greatly improves the loading efficiency; after the third loading plate 4c is opened, the two sides of the third loading plate 4c can be blocked by the baffle plate 13 to prevent the wood waste from falling from the two sides of the opened third loading plate 4c when dumping the wood waste in the transfer frame, thereby ensuring that the wood waste is completely transferred into the loading frame 4.
[0036] By setting a pulling wheel 5b, a pulling rope 5c and a rotating handle 6, a worker can turn the rotating handle 6 to pull the third loading plate 4c upward through the pulling rope 5c, so as to close the third loading plate 4c, and the operation is simple and convenient. At the same time, a linkage rod 16 is set, so that by rotating the rotating handle 6 on one side, the pulling ropes 5c on both sides can pull the two sides of the third loading plate 4c at the same time, so that the third loading plate 4c can be evenly stressed, and the process of the third loading plate 4c rotating upward and closing is more stable.
[0037] By providing the first limiting block 8, the second limiting block 9 and the positioning hole 7a, etc., the third loading plate 4c can be opened and closed by simply pulling the second limiting block 9, which is simple and convenient to operate.
[0038] By providing the support frame 10 and the support block 11, the third loading plate 4c is allowed to contact the support block 11 after being opened, so as to avoid excessive gravity when subsequent wood waste is dumped on the third loading plate 4c, causing wear on the connection between the third loading plate 4c, the first baffle plate and the second baffle plate, thereby extending the service life of the equipment.
[0039] By setting the linkage rod 16, the worker only needs to turn the rotating handle 6 on one side to achieve the synchronous rotation of the two pulling wheels 5b. The pull rope 5c pulls the two sides of the third loading plate 4c at the same time, making the upward rotation process of the third loading plate 4c more stable.
[0040] By providing the first elastic block 14 and the second elastic block, on the one hand, friction between the conveyor belt 3 and the bottom of the loading frame 4 is avoided, which causes wear of the conveyor belt 3; on the other hand, the connection between the loading frame 4 and the conveyor belt 3 is made tighter, so that the wood waste in the loading frame 4 will only be transported forward from the feeding gap with the conveyor belt 3.
[0041] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0042] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
