DETAILED DESCRIPTION

[0027] 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.

[0028] like Figure 1 、 Figure 2 、 Figure 4 and Figure 7 As shown, the utility model is a bamboo and wood crusher, which is used to crush bamboo or wood so that the crushed wood can be subjected to the next process as raw material for papermaking, particle board, etc. or as fuel; specifically, it includes a frame 1, and the frame 1 is provided with a connecting seat 2 serving as a discharge port, that is, a hollow structure is formed in the middle of the connecting seat 2, and the lower part of the connecting seat 2 extends to the frame 1, and the material can be discharged downward through the hollow structure; further, a crushing cavity 3 for crushing materials is provided above the connecting seat 2, and at the same time, a feeding hopper 4 for placing materials is provided above the crushing cavity 3. Materials such as wood are put into the feed hopper 4, and the materials will be crushed in the crushing cavity 3, and then discharged along the discharge port at the lower part of the connecting seat 2.

[0029] Furthermore, in order to achieve the crushing of the material, two groups of crushing knife groups 6 are rotatably arranged in the crushing cavity 3, and the crushing knife group 6 is transmission-connected to one side of the crushing cavity 3 and is arranged on the frame 1. The electric drive device 5, specifically, the crushing knife group 6 also includes a rotating shaft 61 and a blade 62, and a plurality of the blades 62 are evenly and alternately installed in the rotating shaft 61 of the two groups of crushing knife groups 6. One end of the rotating shaft 61 is transmission-connected to the electric drive device 5. Furthermore, as Figure 1 As shown, the electric drive device 5 includes a motor 51 arranged at the bottom of the frame 1 and a gear box assembly 53 arranged on the top surface of the frame 1 and connected to the crushing knife group 6. The motor 51 and the gear box assembly 53 are connected by a synchronous belt device 52. The synchronous belt device 52 is composed of a conveyor belt, a transmission wheel and a protective cover of the conveyor belt, which transmits the power of the motor 51 to the gear box assembly 53. The gear box assembly 53 is composed of a plurality of meshing gear sets, and then the gear set outputs two transmission rods that are respectively connected to the two rotating shafts 61. The meshing connection relationship of the gear sets causes the two rotating shafts 61 to rotate towards each other, so that the blades 62 on the two rotating shafts 61 mesh with each other and crush the input materials.

[0030] Preferably, if Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the side of the crushing chamber 3 away from the gear box assembly 53 is connected to a knife box assembly 7 for collecting the blades 62 pushed in by the crushing knife group 6. The knife box assembly 7 is a cavity structure that can accommodate the blades 62. Furthermore, the knife box assembly 7 includes a hollow box body 71 connected to one side of the crushing chamber 3. The box body 71 is provided with an end cover 72 at one end away from the crushing chamber 3. The rotating shaft 61 is rotatably connected to the end cover 72. The end cover 72 is used to carry the rotation of the rotating shaft 61. Preferably, the rotating shaft 61 can be connected to the end cover 72 through a bearing to reduce the rotational friction; further, the end cover 72 and the box body 71 are arranged in a detachable connection. After the end cover 72 is removed, the blade 62 can be added from the end face of the rotating shaft 61 or the blade 62 can be removed from the rotating shaft 61.

[0031] In order to adjust the distance between the blades 62 in the crushing chamber 3, the distance between the blades 62 can be widened or narrowed as needed. Figure 6 As shown, the figure is a schematic diagram of the structure of the blade 62 of the utility model, including a blade body 621, a blade seat sleeve 622 for mounting on the rotating shaft 61 is formed in the blade body 621, and a blade 623 for crushing materials is formed on the outer surface of the blade body 621. Furthermore, a connecting key 624 is formed in the blade seat sleeve 622, and a threaded through hole is formed in the blade seat sleeve 622, and the threaded through hole is installed with a threaded locking rod 625; accordingly, as shown in FIG. Figure 3 As shown, a keyway corresponding to the connecting key 624 is formed on the rotating shaft 61. When in use, the connecting key 624 is aligned with the keyway and the blade 62 is introduced into the rotating shaft 61, and an appropriate number of blades 62 are introduced. The spacing of the blades 62 is adjusted as needed and the threaded locking rod 625 is tightened against the rotating shaft 61 for fixation. When it is necessary to widen the spacing of the blades 62, it is only necessary to loosen the threaded locking rod 625 and then push the excess blades 62 into the box body 71, and then evenly adjust the width of the blades 62 in the crushing chamber 3. Conversely, the spacing of the blades 62 can be narrowed. It can be adjusted according to different material requirements, making the crusher more adaptable.

[0032] During normal use, since the crushing cavity 3 is connected to the box 71, dust is easily introduced into the box 71. In order to avoid the dust from entering, the present invention is further optimized, such as Figure 3 and Figure 5When the cam 71 is in the unlock state, the locking cam 78 is unlocked, and the lock cam 78 is unlocked, so that the cam 78 can be unlocked.

[0033] When using this crusher, sometimes you will encounter some large and hard wood. When you put these woods into the crusher, they tend to slip on the rotating blade 62, while the wood that is not eaten by the blade 62 is difficult to be crushed. The slippage of this wood will greatly affect the efficiency. Therefore, for further optimization, such as Figure 2 and Figure 7 As shown, the feed hopper 4 is rotatably connected to a pressing assembly 8 for pushing the material toward the crushing knife group 6. Specifically, the pressing assembly 8 includes a pressing rod 81 rotatably connected to the feed hopper 4 and an operating handle 82 fixedly arranged at the end of the pressing rod 81. The pressing rod 81 is located at one end in the feed hopper 4 to form a grabbing claw, which can grab large-sized round wood. Then, by lifting the operating handle 82, the pressing rod 81 is rotated toward the blade 62 and presses down the wood, so that the wood and the blade 62 have a certain fit, and the wood is easily eaten by the blade 62 during rotation, thereby improving the crushing efficiency of the wood, and there is no need for the operator to directly touch the wood for pressing, thereby improving the safety of the personnel.

[0034] The crushed material is usually discharged directly through the discharge port of the connecting seat 2. A receiving container is set below the discharge port, but this method is inconvenient. Therefore, Figure 7 As shown, the present invention is provided with a discharging device 9 for conveying the crushed material directly below the connecting seat 2. Specifically, the discharging device 9 includes a conveyor belt assembly 91 directly below the connecting seat 2 and baffles 92 provided on both sides of the conveyor belt assembly 91 for preventing material leakage. The material can be conveyed from either the left or right side of the frame 1 by controlling the rotation direction of the conveyor belt assembly 91, which makes the placement of the crusher more flexible, and the discharging device 9 also saves labor costs.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
