[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides detachable structures such as a trapezoidal block and a crushing tooth, and utilizes the action of a first spring to bring the trapezoidal block into the inner wall of a rectangular sliding shell, and simultaneously utilizes the driving force of a gear to enable the trapezoidal block to continue to slide in the rectangular sliding shell. The inner wall of the rectangular sliding shell is a trapezoidal structure, so the trapezoidal block will not jump up and down, resulting in failure to mesh with the gear. The sealing plate is used to squeeze the special-shaped rod so that the connecting rod enters the large hole of the figure-eight hole, thereby releasing the crushing tooth from a limited state, and the damaged crushing tooth can be easily taken out for repair or replacement, with high maintenance efficiency, simplicity and speed, and avoids the problem that the crushing tooth is welded or integrally formed, which brings inconvenience to replacement and maintenance.

[0016] 2. The present invention makes it simple and convenient to limit and release the connection rod by setting an eight-shaped hole on the special-shaped rod. When the connection rod is at the small hole position, the inner wall of the small hole is just locked with the inner wall of the concave groove. At the same time, the narrowest part where the inner wall of the large hole and the inner wall of the small hole meet is slightly smaller than the diameter of the inner wall of the concave groove, which ensures that the connection rod will not deviate from the center of the small hole and is stably limited in the small hole. Only when the external force acts on the special-shaped rod can the connection rod enter the large hole and then deviate from the limit of the small hole. See Fig.16 , Fig.17 .

[0017] 3. In order to ensure the accurate corresponding positions of the trapezoidal groove and the through groove, the present invention ensures that the trapezoidal block can slide smoothly along the trapezoidal groove into the through groove. When the rotating shaft is rotated, it is necessary to ensure that the bubble in the spirit level at the stop position of the rotating shaft is at the position indicated by the arrow. At this time, the accurate corresponding positions of the trapezoidal groove and the through groove can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The blocking device includes a fixed shaft 19, which is fixedly connected to the side of the crushing roller 3, a torsion spring 20 is sleeved on the surface of the fixed shaft 19, one end of the torsion spring 20 is fixedly connected to the crushing roller 3, and the other end of the torsion spring 20 is fixedly connected to an L-shaped blocking rod 21, the L-shaped blocking rod 21 is rotatably connected to the surface of the fixed shaft 19, the end of the L-shaped blocking rod 21 is in contact with the trapezoidal block 7, a plurality of mounting blocks 22 distributed in a circular array are fixedly connected to the side of the crushing roller 3, the side of the mounting block 22 is in contact with the L-shaped blocking rod 21, a push rod 23 penetrating the mounting block 22 is slidably connected to the side of the mounting block 22, a push spring 24 is sleeved on the surface of the push rod 23, and the two ends of the push spring 24 are respectively fixed to the mounting block 22 and the push rod 23;

[0041] The release device comprises a rectangular sliding shell 25, which is fixedly connected to the side of the pulverizing shell 1, and a through groove 26 matching the rectangular sliding shell 25 is provided on the side of the pulverizing shell 1, and a penetrating mounting groove is provided on the bottom inner wall of the rectangular sliding shell 25, and a mounting shaft penetrating the mounting groove is rotatably connected to the inner wall of the mounting groove, and a gear 27 is rotatably connected to the surface of the mounting shaft, and the gear 27 is matched with the first tooth plate 8, and a closing plate 28 is fixedly connected to the inner wall of the end of the rectangular sliding shell 25, and a rectangular shell 29 is fixedly connected to the bottom of the rectangular sliding shell 25, and a touch plate 30 is slidably connected to the inner wall of the rectangular shell 29, and the touch plate 30 passes through the pulverizing shell 1, and a second tooth plate 31 is provided on the side of the touch plate 30, and the second tooth plate 31 is matched with the gear 27, and the end of the touch plate 30 is inclined, and the touch plate 30 is matched with the push rod 23 and the rectangular groove 4;

[0042] When working, first stop the equipment, manually rotate the shaft 2 to rotate the damaged crushing tooth 18 to the position corresponding to the release device, that is, the position corresponding to the trapezoidal groove 5 and the through groove 26, install the touch plate 30 into the rectangular shell 29, push the touch plate 30 to slide along the inner wall of the rectangular shell 29, and after the touch plate 30 slides to the position of the gear 27, the second tooth plate 31 on its side will mesh with the gear 27 and drive the gear 27 to rotate. As the touch plate 30 continues to move, the inclined surface at its end will squeeze the push rod 23, and the squeezed push rod The rod 23 will compress the push spring 24 and its end will squeeze the L-shaped blocking rod 21.

At this time, the touch plate 30 has moved to the calibrated position and is no longer pushed to move. The damaged crushing tooth 18 can be easily taken out for repair or replacement, and the repair efficiency is high, simple and quick. After the repair is completed, it can be reset.

[0043] As a further solution of the present invention, a reset plate 32 is fixedly connected to the end surface of the special-shaped rod 11, and a reset spring 33 is connected to the side of the reset plate 32, and the other end of the reset spring 33 is fixedly connected to the surface of the trapezoidal block 7; during operation, after the crushing teeth 18 are replaced, the special-shaped rod 11 needs to be reset, and when the special-shaped rod 11 is under pressure, it drives the reset plate 32 to squeeze the reset spring 33, so that the reset spring 33 stores elastic potential energy, and when the special-shaped rod 11 is reset and the pressure is released, the elastic potential energy of the reset spring 33 is converted into kinetic energy to drive the special-shaped rod 11 to reset.

[0044] As a further solution of the present invention, the power device includes two first gears 34, the first gear 34 is fixedly connected to the end of the rotating shaft 2, the side of the crushing shell 1 is fixedly connected to a motor, the end of the output shaft of the motor is fixedly connected to a second gear 35, the side of the crushing shell 1 is rotatably connected to a third gear 36, the second gear 35 is meshed with the first gear 34 and the third gear 36, and the second gear 35 and the third gear 36 are gears of the same specification; when working, the second gear 35 and the second gear 35 are gears of the same specification, that is, the module, the number of teeth and other parameters are the same, so when driving the first gear 34 to rotate, the rotation speed of the two first gears 34 remains the same, thereby ensuring the efficiency of crushing.

[0045] As a further solution of the present invention, a mounting plate is fixedly connected to the side of the first gear 34, a spirit level 37 is fixedly connected to the top surface of the mounting plate, and an arrow is provided on the side of the spirit level 37; during operation, in order to ensure that the corresponding positions of the trapezoidal groove 5 and the through groove 26 are accurate, and to ensure that the trapezoidal block 7 can slide smoothly along the trapezoidal groove 5 into the through groove 26, when the rotating shaft 2 is rotated, it is necessary to ensure that the bubble in the spirit level 37 at the stop position of the rotating shaft 2 is at the position indicated by the arrow, and at this time, the corresponding positions of the trapezoidal groove 5 and the through groove 26 can be guaranteed to be accurate.

[0046] As a further solution of the present invention, two fixed blocks 38 are fixedly connected to the top of the connecting rod 15, and a placement groove 39 is opened on the top surface of the trapezoidal block 7, and the fixed block 38 is slidably connected to the inner wall of the placement groove 39; during operation, since the connecting rod 15 at the bottom of the crushing tooth 18 is circular, it can rotate. In order to prevent it from rotating, the fixed block 38 is set so that when the crushing tooth 18 is installed in place, the fixed block 38 will enter the placement groove 39, thereby avoiding the problem of rotation of the crushing tooth 18.

[0047] As a further solution of the present invention, two limit plates 40 are fixedly connected to the inner wall end of the rectangular shell 29, and the touch plate 30 and the limit plate 40 are slidably connected; when working, the limit plate 40 is set to limit the left and right sliding of the touch plate 30, so that it can move in a predetermined direction, preventing the touch plate 30 from failing to enter the rectangular groove 4 due to excessive left and right shaking.
