DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0025] like Figures 1 to 6 As shown, a crusher with easily removable crushing teeth comprises a shell 1 and a crushing part 2 installed inside the shell 1 for crushing garbage. The shell 1 comprises a base 12 and a pressure seat 13 installed on the upper and lower sides of the crushing part 2. One end of the pressure seat 13 is hinged on the base 12 for opening the interior of the shell 1. A plurality of detachable crushing teeth 22 are arranged on the crushing roller 21 of the crushing part 2. The crushing teeth 22 are formed by two identical semicircular teeth spliced ​​and locked with each other.

[0026] The base 12 and the pressure seat 13 form a rectangular processing chamber, and semicircular holes are provided on the opposite surfaces of the base 12 and the pressure seat 13. The two semicircular holes on the base 12 and the pressure seat 13 are combined to form a circular hole for installing the bearing sleeves 23 at both ends of the crushing roller 21. One end of the crushing roller 21 is fixedly connected with a power member 24, which is composed of a motor and a reducer. The base 12 supports the crushing roller 21, and the semicircular holes on the pressure seat 13 cooperate with the semicircular holes on the base 12 to form a circular hole to limit the crushing roller 21, which can prevent the crushing roller 21 from moving on the one hand and the crushing roller 21 from shaking on the other hand.

[0027] The base 12 is fixed on the work frame 11, the lower outlet of the base 12 is connected to the discharge port 17, and the upper surface of the pressure seat 13 is fixedly connected with the upper hopper 14. During crushing, the garbage is loaded through the upper hopper 14, and the garbage enters the processing bin composed of the base 12 and the pressure seat 13 along the upper hopper 14 and is crushed by two crushing rollers 21 that rotate inversely with each other driven by two power members 24 inside. After crushing, the garbage falls into the discharge port 17 below for discharge and is finally recycled.

[0028] A receiving groove 111 is provided on the surface of the work frame 11 on one side of the base 12, and a screw rod 15 is rotatably connected inside the receiving groove 111. The outer wall of the screw rod 15 is sleeved with a moving foot 161 at one end of the support rod 16, and the hinged foot 162 at the other end of the support rod 16 is fixed to the lower surface of the convex plate 131 fixedly connected to the side of the press seat 13. By rotating the screw rod 15, the screw rod 15 drives the lower end of the support rod 16 to move to the other side, pushing the hinged foot 162 at the upper end of the other side of the support rod 16 to push the convex plate 131 up under the convex plate 131, and the convex plate 131 drives one side of the press seat 13 fixedly connected thereto to rise, and at the same time, the other side of the press seat 13 rotates with the axis hinged to the base 12 as the rotation axis, thereby opening the processing chamber composed of the press seat 13 and the base 12, exposing the internal crushing roller 21 for convenient replacement by the user.

[0029] A plurality of positioning rings 211 are equidistantly arranged on the surface of the crushing roller 21, and the positioning rings 211 correspond to the limiting grooves 225 provided inside the crushing teeth 22. The inner wall of the crushing teeth 22 engages with the outer wall of the positioning ring 211 fixedly arranged on the surface of the crushing roller 21 through the limiting grooves 225, so as to prevent the crushing teeth 22 from moving on the surface of the crushing roller 21 along the axial direction of the crushing roller 21, thereby ensuring the normal use of the crushing teeth 22.

[0030] The two ends of the two semicircular teeth are respectively a left step 221 and a right step 222. The left step 221 is provided with a slot 2211 which is engaged with a block 2221 on the right step 222. The left step 221 is provided with a locking rod 223 which is used to engage with a locking hole 224 provided on the surface of the right step 222. One of the semicircular teeth is connected with the right step 222 of the other semicircular tooth through its own left step 221 and is engaged with the slot 2211 through the block 2221. It is also locked with the locking rod 223 and the locking hole 224. At the same time, the right step 222 of the semicircular tooth is locked by the left step 221 of the other semicircular tooth through the locking rod 223, thus completing the combination of the complete crushing tooth 22.

[0031] The locking rod 223 includes a rotating sleeve 2231, inside which is provided a straight rod 2232 that slides with a keyway, between which is provided a spring 2233 for pushing the straight rod 2232 outward, and the front end of the straight rod 2232 is provided as an inclined surface, and its cross section is a right-angled trapezoid. A key is provided on the side of the straight rod 2232, and the key slides in a limited position in the key slot provided on the inner wall of the rotating sleeve 2231, and is used to connect the rotating sleeve 2231 with the straight rod 2232, so that the rotating sleeve 2231 on the outside drives the straight rod 2232 on the inside to rotate. The outer side of the rotating sleeve 2231 is arranged in a knob shape for the convenience of the user's twisting. The inclined surface is arranged so that when the straight rod 2232 is split, it can be retracted and unlocked through the squeezing action of the locking hole 224 on the inclined surface, or when installing, the straight rod 2232 is retracted through the squeezing action of the end face of the left step 221, and then the spring 2233 rebounds and is reinserted into the locking hole 224. The cross-section of the straight rod 2232 along the axial direction is a right-angled trapezoid.

[0032] Step 1: When opening the inside of the shell 1, the user holds the handle at one end of the screw rod 15 and rotates it. The rotation of the screw rod 15 drives the moving foot 161 to move along the receiving groove 111. One end of the moving foot 161 pushes the other end of the support rod 16 to rise. The rise of the other end of the support rod 16 drives the pressure seat 13 to rise through the hinged foot 162 and the convex plate 131. At the same time, the pressure seat 13 rotates with the hinge shaft on the other side hinged to the base 12 as the rotation axis, and the pressure seat 13 and the upper hopper 14 fixed on its upper surface are lifted up, opening the processing warehouse composed of the pressure seat 13 and the base 12.

[0033] Step 2: When removing the old crushing tooth 22, find the crushing tooth 22 that needs to be replaced, and rotate the locking rod 223 on its side, rotate the rotating sleeve 2231, and drive the internal limited straight rod 2232 to rotate as well, so that the inclined surface of the straight rod 2232 on the semicircular tooth at the bottom is rotated downward, and the inclined surface of the straight rod 2232 in the semicircular tooth at the top is rotated upward, and then the two semicircular teeth are pulled to the upper and lower sides respectively. During the pulling process, the inclined surface accommodates the locking hole 224 of the other semicircular tooth and squeezes it to shrink, thereby unlocking the two semicircular teeth, thereby separating the crushing tooth 22 from the crushing roller 21.

[0034] Step 3: When replacing a new semicircular tooth, first rotate the inclined surface of the straight rod 2232 on the upper semicircular tooth downward, and rotate the inclined surface of the straight rod 2232 on the lower semicircular tooth upward, then align the lower semicircular tooth with the limiting groove 225 and the positioning ring 211 for installation. When the lower semicircular tooth is fitted with the crushing roller 21, align the upper semicircular tooth with the lower semicircular tooth and the positioning ring 211 for pressing and plugging, so that the straight rod 2232 shrinks and resets to complete the locking. Then, rotate the two locking rods 223 ninety degrees to complete the locking, and replace all the crushing teeth 22 to be replaced one by one.

[0035] Finally, the screw rod 15 is rotated in the reverse direction, and the rotation of the screw rod 15 drives the moving foot 161 to return to its original position, thereby lowering the other end of the support rod 16, and finally the pressing seat 13 is re-closed on the base 12.
