As shown in fig. 2, in one embodiment, the wood chopping knife body 320 includes a plurality of active knife bodies 322, the plurality of active knife bodies 322 are spaced apart along the circumferential wall of the mounting cylinder 310, and the plurality of active knife bodies 322 are all connected to the mounting cylinder 310. Each of the driving cutter bodies 322 is configured to move through a material passing gap between two adjacent positioning bed cutters 330 when rotating with the mounting cylinder 310 relative to the machine body 100, so that the wood cutter bodies 320 continuously crush materials. In this embodiment, the number of the positioning bed blades 330 is plural, and the plural positioning bed blades 330 are arranged side by side. Any active cutter body 322 located in the same wood cutter body 320 moves through the material passing gap between two adjacent positioning bed cutters 330 when rotating with respect to the machine body 100 along with the installation cylinder body 310.

As shown in fig. 4 and 5, further, the number of the wooden chopper bodies 320 is at least two, two adjacent wooden chopper bodies 320 are arranged side by side along the axial direction of the installation cylinder 310, the arrangement direction of the two adjacent wooden chopper bodies 320 is parallel to the arrangement direction of the plurality of positioning bed knives 330, any one of the driving chopper bodies 322 located in the same wooden chopper body 320 moves through the material passing gap between the two same adjacent positioning bed knives 330 when the installation cylinder 310 rotates relative to the machine body 100, and for different wooden chopper bodies 320, the material passing gap between the two adjacent positioning bed knives 330 through which each driving chopper body 322 of the wooden chopper body 320 passes is also different, so that the installation cylinder 310 simultaneously drives at least two wooden chopper bodies 320 to rotate during the rotation relative to the machine body 100, thereby improving the crushing efficiency of the wood crusher 10. In this embodiment, the distance between two adjacent active cutter bodies 322 located in the same wood cutter body 320 is the same, so that the time interval between each active cutter body 322 located in the same wood cutter body 320 passing through the material passing gap between two adjacent positioning bed cutters 330 is the same.

As shown in fig. 2, in one embodiment, the distribution angles of any two adjacent active cutter bodies 322 of the wood cutter bodies 320 in the circumferential direction of the mounting cylinder 310 are equal, so that the time interval of each active cutter body 322 passing through the material passing gap between two adjacent positioning bed cutters 330 is the same, and thus the same wood cutter body 320 can better break the wood.

As shown in fig. 2, the cylindrical mounting body 310 has a cylindrical shape, so that the cylindrical mounting body 310 has a simple structure and the wooden chopper body 320 can be easily mounted. Further, the projections of the active cutter bodies 322 of two adjacent wood cutter bodies 320 on the installation cylinder 310 are located on different generatrices of the installation cylinder 310, that is, the two adjacent active cutter bodies 322 of two adjacent wood cutter bodies 320 are staggered and distributed on different generatrices of the installation cylinder 310, so that the wood crusher 10 can crush wood well.

As shown in fig. 2, each of the active cutter bodies 322 is further welded to the mounting cylinder 310, such that each of the active cutter bodies 322 is firmly connected to the mounting cylinder 310. It is understood that in other embodiments, each active cutter body 322 is not limited to being welded to the mounting cylinder 310. For example, each active blade 322 is glued to the mounting cylinder 310.

As shown in fig. 2 and 13, each of the active cutter bodies 322 includes a cutter body fixing portion 322a, a blade portion 322b, and a reinforcing portion 322c, the cutter body fixing portion 322a is connected to the blade portion 322b and the reinforcing portion 322c, the cutter body fixing portion 322a, the blade portion 322b, and the reinforcing portion 322c are connected to the mounting cylinder 310, the blade portion 322b and the reinforcing portion 322c are located at both sides of the cutter body fixing portion 322a, respectively, and the blade portion 322b is provided with a cutting edge oriented in a tangential direction to a rotation direction of the mounting cylinder 310, so that the blade portion 322b can better crush the wood material along with the rotation direction of the mounting cylinder 310. Since the reinforcing part 322c is connected to the mounting cylinder 310 and the blade body fixing part 322a, respectively, the strength of the blade body fixing part 322a is increased, so that the active blade body 322 is not deformed or even broken during the process of crushing wood.

As shown in fig. 13, the blade body fixing portion 322a, the blade portion 322b, and the reinforcing portion 322c are integrally formed, so that the structure of the driving blade body 322 is more compact, and the blade body fixing portion 322a, the blade portion 322b, and the reinforcing portion 322c are firmly coupled. It is understood that the blade body fixing portion 322a, the blade portion 322b and the reinforcing portion 322c are not limited to being integrally formed in other embodiments. For example, the blade body fixing portion 322a, the blade portion 322b, and the reinforcing portion 322c may be formed separately and connected by welding or gluing.

Furthermore, the included angle between the extending direction of the cutting edge and the tangential direction of the mounting cylinder body 310 connected to the cutting edge is 5-15 degrees, so that the cutting edge can better crush the wood along the rotating direction of the mounting cylinder body 310.

Although the positioning bed knife 330 performs a screening function similar to a screen, when the wood cutter body 320 rotates along with the installation cylinder body 310 and passes through the material passing gap, the wood is crushed by the cooperation of the wood cutter body 320 and the positioning bed knife 330, but it is not excluded that part of the crushed wood with larger volume is directly discharged through the material passing gap, so that the qualified rate of crushing of the wood crusher 10 is poor. In order to improve the qualification of the wood crusher 10 in crushing, in one embodiment, the crushing mechanism 300 further includes a repositioning assembly 340, the repositioning assembly 340 is disposed on the inner wall of the crushing chamber 120, the repositioning assembly 340 is located between each of the positioning bed knives 330 and the bottom of the inner wall of the crushing chamber 120, the repositioning assembly 340 is disposed adjacent to the mounting cylinder 310, and the repositioning assembly 340 is configured to perform secondary crushing on crushed wood passing through a material passing gap between two adjacent positioning bed knives 330 together with the crushed wood cutter body 320, so as to avoid direct discharging of the crushed wood with a large volume, and improve the crushing rate of the crushing mechanism 300 on wood.

In this embodiment, the number of the positioning bed blades 330 is plural, the positioning bed blades 330 are arranged on the machine body 100 side by side, and the positioning bed blades 330 form a primary positioning assembly.

The primary positioning component and the secondary positioning component 340 are sequentially arranged on the machine body 100 at intervals along the rotating direction of the mounting cylinder body 310, when the wood chopping cutter bodies 320 rotate along the mounting cylinder body 310 and pass through the material passing gaps of the two corresponding adjacent driving cutter bodies 322, part of the crushed wood with large volume passes through the material passing gaps, and because the primary positioning component and the secondary positioning component 340 are sequentially arranged on the machine body 100 at intervals along the rotating direction of the mounting cylinder body 310, the crushed wood passing through the material passing gaps is crushed again in the process that the driving cutter bodies 322 pass through the two adjacent screening bed knives 344, and the crushing rate of the wood by the crushing mechanism 300 is greatly improved.

As shown in fig. 4 and 5, further, a gap between two adjacent positioning bed knives 330 is a first gap 332, a gap between two adjacent screening bed knives 344 is a second gap 344a, and the first gap 332 is greater than or equal to the second gap, so that the crushed wood with a larger volume passes through the first gap 332 and is not easy to pass through the second gap 344a, and thus the crushed wood passing through the material passing gap is crushed again in the process that the active knife body 322 passes through two adjacent screening bed knives 344.

As shown in fig. 2 and 5, the fixing plate 342 is welded to the machine body 100, so that the fixing plate 342 is fixed to the machine body 100. In other embodiments, the fixing plate 342 is not limited to be welded to the machine body 100. For example, the fixing plate 342 is integrally formed with the machine body 100, so that the fixing plate 342 is firmly connected with the machine body 100.

As shown in fig. 2, 3 and 10, in order to fixedly connect each of the screening bed cutters 344 to the fixing plate 342 in an inclined manner, an inclined surface 342a is provided at a side of the fixing plate 342 connected to each of the screening bed cutters 344, so that each of the screening bed cutters 344 is fixedly connected to the fixing plate 342 in an inclined manner. In this embodiment, one of the mounting cylinders 310 is perpendicular to the inclined surface in a radial direction, so that the mounting cylinder 310 can better crush wood while driving the driving blade body 322 to pass through two adjacent screening bottom cutters 344.

As shown in fig. 4 and 5, in order to make each of the screening blades 344 better fit with the active blade body 322 to cut the wood, further, each of the screening blades 344 extends in a direction perpendicular to the inclined surface, so that each of the screening blades 344 is vertically fixed to the surface of the inclined surface, and thus each of the screening blades 344 better fits with the active blade body 322 to cut the wood.

As shown in fig. 4 and 5, a plurality of the screening bed cutters 344 are welded to the fixing plate 342, so that the plurality of the screening bed cutters 344 are fixedly connected to the fixing plate 342. It is understood that in other embodiments, the plurality of screen bed cutters 344 are not limited to being welded to the stationary plate 342. For example, a plurality of the screening bed cutters 344 are glued to the stationary plate 342.

In order to make each positioning blade better cooperate with the driving blade body 322 to cut wood, further, each positioning bed knife 330 is provided with a first positioning blade, which is arranged toward the mounting cylinder 310, so that each positioning blade body better cooperates with the driving blade body 322 to cut wood.

In order to make each screening cutter body better fit with the driving cutter body 322 for cutting wood, further, each screening bed cutter 344 is provided with a second positioning blade for being disposed toward the mounting cylinder 310 so that each screening cutter body better fits with the driving cutter body 322 for cutting wood.

As shown in fig. 2, in one embodiment, the machine body 100 further defines a discharge hole 102 communicated with the crushing cavity 120, the wood crusher 10 further includes a discharge mechanism 600, the discharge mechanism 600 is disposed on the machine body 100, the discharge mechanism 600 is disposed corresponding to the discharge hole, and the discharge mechanism 600 is configured to discharge the crushed materials, so that the crushed materials are discharged through the discharge mechanism 600. In this embodiment, the discharging mechanism 600 is a belt conveying mechanism, the discharging mechanism 600 is located below the crushing mechanism 300, and the crushed materials fall to the discharging mechanism 600 and are output through the discharging mechanism 600.

As shown in fig. 2 and 10, the material pushing groove 110 further includes a material inlet 112, a material storage cavity 114 and a material pushing cavity 116, the material inlet 112 is communicated with the material pushing cavity 116 through the material storage cavity 114, and the material pushing cavity 116 is communicated with the crushing cavity 120 through the material storage cavity 114. The feeding port 112 is communicated with the material placing cavity 210, so that the material placing cavity 210 is communicated with the crushing cavity 120 through the material pushing groove 110. The pushing element main body 512 of the pushing mechanism 500 slides back and forth between the material storage cavity 114 and the pushing cavity 116, so that the pushing mechanism 500 is used for pushing the material in the pushing trough 110 into the crushing cavity 120, the material in the pushing trough 110 is pushed into the crushing cavity 120, wood is not erected above the mounting cylinder 310, wood crushing is continuously performed, the effective crushing time of the wood crusher 10 is prolonged, and the wood crushing efficiency is improved. In this embodiment, the material placing cavity 210 is located right above the material inlet 112, the material pushing cavity 116 is located at the left side of the material storing cavity 114, and the crushing cavity 120 is located at the right side of the material storing cavity 114. Because the mounting cylinder 310 is rotatably connected to the machine body 100, and the crushing mechanisms 300 are all located in the crushing cavity 120, that is, the crushing mechanisms are not arranged right opposite to the material inlet 112, so that the material directly falls into the material storage cavity 114 through the material inlet 112 after entering through the material storage cavity 210, the material pushing mechanism 500 pushes the material into the crushing cavity 120 in the process of moving from the material pushing cavity 116 to the material storage cavity 114, so that the material in the material storage cavity 114 is pushed into the crushing cavity 120 through the material pushing mechanism 500, and the crushing mechanisms and the material inlet 112 are arranged in a staggered manner, the problem that the driving cutter body 322 cannot act on the wood in the rotating process of the mounting cylinder 310 to idle and is started again after being stopped and cleaned is avoided, the problem that the wood is 'overhead' in the production process is completely eradicated, and the capacity of the wood crusher 10 is greatly improved.

As shown in fig. 2 and 10, further, a projection of the feeding port 112 in the vertical direction is located on a bottom wall of the stock cavity 114. The crushing cavity and the discharge hole are both arranged at a position close to one end of the machine body 100, and the material pushing cavity 116 is arranged at a position close to the other end of the machine body 100, so that the space of the material storage cavity 114 is larger, and the problems that the driving cutter body 322 cannot act on wood in the rotating process of the mounting cylinder body 310 to idle, and needs to be stopped for cleaning and then started again are better solved.

As shown in fig. 2 and 10, in order to better crush the material pushed into the crushing chamber 120 through the crushed wooden knife body 320, the width of the opening of the crushing chamber communicated with the storage chamber 114 in the rotation plane of the mounting cylinder body 310 is smaller than or equal to the diameter of the mounting cylinder body 310, so that the material pushed into the crushing chamber 120 is better crushed through the crushed wooden knife body 320. In this embodiment, in the process that the pushing material main body 512 pushes the material in the pushing chute 110 into the crushing cavity 120, at least part of the pushing material main body 512 is located in the pushing cavity 116, so that at least part of the pushing material main body 512 is located in the pushing cavity 116 in the process of pushing the material, thereby preventing the material from entering the pushing cavity 116 partially in the pushing process of the pushing material main body 512 to affect the reset of the pushing material main body 512, that is, preventing the pushing mechanism 500 from being jammed, and improving the reliability of the wood crusher 10.

As shown in fig. 2, in order to make the pushing member main body 512 push the material into the crushing cavity 120 better, further, the thickness of the pushing member main body 512 is equal to the depth of the material storage cavity 114, so that the pushing member main body 512 pushes the material in the material storage cavity 114 into the crushing cavity 120 better. It is understood that in other embodiments, the thickness of the pusher body 512 is not limited to being equal to the depth of the storage cavity 114. For example, the pusher body 512 has a thickness less than the depth of the storage chamber 114.

As shown in fig. 2 and 10, further, the rotation center of the mounting cylinder 310 is lower than the central plane of the material pushing member main body 512, so that a portion of the mounting cylinder 310 is exposed to the material storage cavity 114, and further, the surface area of the wood chopping knife body 320 of the mounting cylinder 310 and the primary positioning assembly for matching with wood chopping is smaller, so that the torque required during the rotation of the mounting cylinder 310 relative to the machine body 100 is smaller, and the situation that the material crushing mechanism 300 is jammed during the wood chopping process is avoided.

As shown in fig. 4 and 5, the mounting cylinder 310 further includes a mounting cylinder body 312 and a rotating shaft 314, the rotating shaft 314 is rotatably connected to the machine body 100, and the mounting cylinder body 312 is sleeved on the rotating shaft 314, so that the mounting cylinder 310 is rotatably connected to the machine body 100. In the present embodiment, the chipper body 320 is provided on the surface of the mounting cylinder body 312. Specifically, the machine body 100 is further provided with a first mounting hole and a second mounting hole, and the first mounting hole and the second mounting hole are both communicated with the crushing cavity. The material pushing cavity 116 is communicated with the crushing cavity through the material storing cavity 114. The rotating shaft 314 is respectively inserted into the first mounting hole, the crushing cavity and the second mounting hole, and the rotating shaft 314 is rotatably connected to the machine body 100, so that the rotating shaft 314 is rotatably connected to the machine body 100.

As shown in fig. 9, further, the driving mechanism 400 includes a motor 410, a first pulley 420, a second pulley 430 and a transmission belt 440, the motor 410 is mounted on the machine body 100, the first pulley 420 is sleeved on a power shaft of the motor 410, the second pulley 430 is sleeved on the rotating shaft 314, and the transmission belt 440 is respectively sleeved on the first pulley 420 and the second pulley 430, so that a power output end of the driving mechanism 400 is connected to the mounting cylinder 310. In the present embodiment, the power shaft of the motor 410 drives the transmission shaft to rotate relative to the machine body 100 through a belt transmission manner. It is understood that in other embodiments, the power shaft of the motor 410 can drive the transmission shaft to rotate relative to the machine body 100 through a chain transmission or a gear transmission.

However, when the pushing mechanism 500 pushes the material from the pushing chute 110 into the crushing cavity 120 and the material is crushed by the crushing mechanism, the pushing mechanism 500 may push the material too tightly when the pushing mechanism 500 pushes the material too fast, which may cause overload or overload of the motor 410 during the rotation of the driving installation cylinder 310 relative to the machine body 100. In order to avoid the problem of overload or overload of the motor 410 during the rotation of the driving installation cylinder 310 relative to the machine body 100, the wood crusher 10 further includes a controller, and the controller is electrically connected to the control end of the motor 410 and the control end of the pushing material driving assembly 520, respectively. When the controller monitors that the output power of the motor 410 is greater than or equal to the preset power value and the duration time exceeds the first preset time, that is, when the controller monitors that the load of the motor 410 is too large and exceeds the set time, the controller controls the material pushing driving assembly 520 to drive the material pushing member 510 to move in the direction away from the mounting cylinder 310 for a second preset time, so that the material pushing member 510 retreats for a certain distance, the compressed wood is loosened and crushed, and the problem that the motor 410 is overloaded or overloaded in the process of driving the mounting cylinder 310 to rotate relative to the machine body 100 is solved. It can be understood that only when the output power of the motor 410 is greater than or equal to the preset value and the duration exceeds the first preset time, the controller controls the pushing driving assembly 520 to drive the pushing member 510 to move in the direction away from the mounting cylinder 310, so as to avoid that the pushing driving assembly 520 is controlled by mistake to drive the pushing member 510 to move in the direction away from the mounting cylinder 310 due to short overload or excessive load. Further, the preset power value is larger than or equal to the rated power of the motor 410, so that the problem of overload damage of the motor 410 is avoided. In this embodiment, the first preset time is set as needed. Further, the second preset time is 1-5 s, so that the compressed wood is well loosened and crushed.

1. because the hopper 200 is provided with the material placing cavity 210, and the material placing cavity 210 is communicated with the crushing cavity 120 through the material pushing groove 110, the wood falls into the material pushing groove 110 through the material placing cavity 210, the material pushing mechanism 500 pushes the material in the material pushing groove 110 into the crushing cavity 120, the wood feeding process is realized, the hopper does not need to move left and right in the feeding process, the traditional feeding mode that the hopper moves left and right is changed, and the service life of the wood crusher and the feeding safety are improved;

2. the timber in the material placing cavity 210 is directly pushed into the crushing cavity 120 through the material pushing mechanism 500, so that the problem that a traditional belt-type feeding inlet 220 is small is solved, only the timber needs to be fed through the material placing cavity 210 in the material crushing process, the feeding efficiency of the timber crusher 10 is greatly improved, and the processing efficiency of the timber crusher 10 is further improved;

3. because the wood chopping knife body 320 is arranged on the outer peripheral wall of the mounting cylinder body 310, the mounting cylinder body 310 is positioned in the crushing cavity 120 and is rotatably connected with the machine body 100, the at least two positioning bed knives 330 are arranged side by side at the position of the inner wall of the crushing cavity 120 adjacent to the inner wall of the material pushing groove 110, the side by side direction of the at least two positioning bed knives 330 is parallel to the rotating central line of the mounting cylinder body 310, the wood chopping knife body 320 passes through the material passing gap between the two positioning bed knives 330 when rotating along with the mounting cylinder body 310 relative to the machine body 100, so that the wood chopping knife body 320 and the positioning bed knives 330 are matched together to machine the crushed materials into the crushed materials, thus the wood with larger volume is blocked by the positioning bed knives 330 and can not directly enter the crushing cavity 120, the wood is chopped when the wood chopping knife body 320 passes through the material passing gap between the two positioning bed knives 330 along with the mounting cylinder body 310, and the problem that the crushed materials can not pass through the, the positioning bed knife 330 plays a role in filtering and screening, and because the installation cylinder body 310 does not need to be additionally provided with a screen for filtering and screening, the situation that the rotary cylinder is easy to block is avoided, the smooth degree of crushed material discharging is improved, the crushed material efficiency of the wood crusher 10 is further improved, the consumption of the screen is reduced, and the use cost of the wood crusher is greatly reduced;
