[0050] In the embodiment, please refer to Figure 3 , Figure 4 and Figure 5 , the knocking plate 15 comprises a first sub-plate 151, a second sub-plate 152 and a third sub-plate 153, the second sub-plate 152 is fixedly connected with the third sub-plate 153, one end of the third sub-plate 153 is matchedly connected with the corresponding sliding groove 131, one end of the first sub-plate 151 is provided with a first sub-groove 159, the extension end of the second sub-plate 152 is slidably connected with the first sub-groove 159, the other end of the first sub-plate 151 is matchedly connected with the corresponding sliding groove 131, and a limiting groove 154 is arranged in the first sub-groove 159. The design of the first sub-plate 151, the second sub-plate 152 and the third sub-plate 153 can ensure that the knocking plate 15 can rotate and stably operate when the displacement amounts of the two ends of the knocking plate 15 are different.

[0051] In the embodiment, please refer to Figure 5 , Figure 6 , the two side walls of the limiting groove 154 are each provided with a limiting sub-groove 156, the two ends of the limiting sliding block 16 are slidably connected with the limiting sub-groove 156, a reciprocating rod 168 that can synchronously rotate is arranged in the limiting sub-groove 156, the reciprocating rod 168 is provided with a first reciprocating thread 1681, and the limiting sliding block 16 is provided with a reciprocating hole through which the reciprocating rod 168 passes and which is matchedly connected with the first reciprocating thread 1681. Through the rotation of the reciprocating rod 168, the periodic reciprocating movement of the limiting sliding block 16 in the limiting groove 154 is automatically realized by using the characteristics of the reciprocating thread.

[0052] In the embodiment, please refer to Figure 5 , Figure 6 , a driving shaft 169 that is rotationally connected is arranged in the limiting sub-groove 156, the limiting sliding block 16 is provided with a driving hole through which the driving shaft 169 passes, the limiting sliding block 16 is provided with a driving ring plate 164 that is rotationally connected, the driving shaft 169 is provided with a synchronous groove 166, the driving shaft 169 passes through the middle part of the driving ring plate 164, the inner wall of the driving ring plate 164 is provided with a synchronous block that is fixedly connected and slidably connected with the synchronous groove 166, the first synchronous chain 167 that is connected is arranged between the adjacent driving shaft 169 and the reciprocating rod 168, the output shaft 163 is arranged at the output end of the knocking motor 162, the output shaft 163 is connected with the knocking cam 161, and the second synchronous chain 165 that is connected is arranged between the output shaft 163 and the corresponding driving ring plate 164.

[0053] The design of the driving shaft 169, the driving ring plate 164, the synchronous block and the synchronous slot 166 can enable the driving ring plate 164 to reciprocate along the driving shaft 169 during rotation. The design of the first synchronous chain 167 between the driving shaft 169 and the reciprocating rod 168 and the second synchronous chain 165 between the output shaft 163 and the driving ring plate 164 can enable the driving motor to drive the knocking cam 161 to rotate, and at the same time, drive the driving ring plate 164 to rotate through the second synchronous chain 165. The rotation of the driving ring plate 164 can drive the driving shaft 169 to rotate, and the rotation of the driving shaft 169 can continuously drive the reciprocating rod 168 to rotate. In combination with the characteristics of the reciprocating thread, the limiting sliding block 16 can automatically reciprocate in the limiting slot 154, so that the knocking cam 161 can reciprocate while knocking.

[0054] In the embodiment, please refer to Figure 4 、 Figure 7 The adjusting shaft 174 is provided with a second reciprocating thread 172, the fixed block 17 is provided with an adjusting hole through which the adjusting shaft 174 passes and which is matched with the second reciprocating thread 172, the knocking plate 15 is provided with a driving mechanism for driving the adjusting shaft 174 to rotate, the driving mechanism comprises a driving rack 178 and a driving gear 176, the knocking plate 15 is provided with a through-type communication slot 158 at each end for communicating with the adjacent adjusting shaft 174, the communication slot 158 is provided with the driving gear 176 which is rotatably connected, the driving gear 176 is provided with a central shaft 177 which is rotatably connected, the central shaft 177 and the corresponding adjusting shaft 174 are provided with the third synchronous chain 175 which is connected, the knocking plate 15 is provided with a transverse slot 157 which transversely passes through the communication slot 158, the driving rack 178 is movably arranged in the transverse slot 157, and the driving rack 178 is engaged with the corresponding driving gear 176. Since the discharge hopper 12 is in the shape of an inverted quadrangular prism, the side surface of the discharge hopper 12 is in the shape of a trapezoid, so that during the movement of the knocking plate 15, the displacement of the upper end of the knocking plate 15 is greater than that of the lower end of the knocking plate 15 each time. The different displacement can be controlled by setting different pitches of the second reciprocating thread 172, so as to realize better movement of the two ends of the knocking plate 15 to one side.

[0055] The movement of the driving rack 178 drives the driving gear 176 to rotate through the engagement of the gear, and the rotation of the driving gear 176 drives the adjusting shaft 174 to rotate through the central shaft 177 and the third synchronous chain 175, so that the adjusting shaft 174 is automatically rotated. In combination with the characteristics of the reciprocating thread, the position of one end of the knocking plate 15 is automatically changed, and the end of the knocking plate 15 can automatically move back to the set position.

[0056] In the embodiment, please refer toFigure 7 、 Figure 8 One of the transverse grooves 157 communicates with one end of the corresponding limiting sub-groove 156, and the end of the drive rack 178 is located in the limiting sub-groove 156. The other transverse groove 157 is arranged in the third plate, and the first hydraulic telescopic rod 1593 fixedly connected is arranged in the other transverse groove 157. The end of the first hydraulic telescopic rod 1593 is fixedly connected with the corresponding drive rack 178. The second hydraulic telescopic rod 1592 fixedly connected is arranged on the other side of the limiting sub-groove 156. The connecting hose 1591 is arranged in the first sub-groove 159. One end of the connecting hose 1591 communicates with the first hydraulic telescopic rod 1593, and the other end of the connecting hose 1591 communicates with the second hydraulic telescopic rod 1592. Reset springs 1783 for driving the drive rack 178 to automatically return to the initial position are arranged in the two transverse grooves 157. The automatic extrusion of the drive rack 178 can be realized by the movement of the limiting sliding block 16 to both ends of the limiting sub-groove 156, so that the automatic change of the positions of both ends of the knocking plate 15 is realized. The reset groove 1782 is arranged on the side wall of the transverse groove 157. The reset block 1781 slidingly connected is arranged in the reset groove 1782. The reset block 1781 is fixedly connected with the drive rack 178. The reset spring 1783 is arranged in the reset groove 1782, and the reset spring 1783 is used to drive the reset block 1781 to automatically return to the initial position.

[0057] In this embodiment, please refer to Figure 2 、 Figure 3 The sides of the plurality of discharge hoppers 12 are flush. The support frames 11 fixedly connected are arranged between the plurality of raw material boxes 1. The fixed plates 13 are fixedly connected with the corresponding support frames 11 at both ends, and are arranged on the same side of the discharge hoppers 12 which are flush. The plurality of locking holes 132 are arranged on the fixed plates 13. The locking bolts 14 are arranged in the locking holes 132. The bolt holes 171 matched with the locking bolts 14 are arranged on the fixed blocks 17. Since not all raw material boxes 1 will be cemented at the same time, such a design can realize that only one knocking motor 162 is needed to knock the discharge hoppers 12 of the plurality of raw material boxes 1, thereby reducing the overall cost.

[0058] In use, the embodiment has the following advantages:

[0059] When one of the discharge hoppers 12 is cemented and the discharge port is blocked, the locking bolt 14 is first rotated to release the fixation between the fixed block 17 and the sliding groove 131. Then the knocking plate 15 is moved to the blocked discharge hopper 12, and the fixed block 17 and the sliding groove 131 are fixedly connected through the threaded connection of the locking bolt 14 and the bolt hole 171.

[0060] At this time, the knocking motor 162 is started to drive the rotation of the knocking cam 161, and the side wall of the discharge hopper 12 is vibrated and knocked. The rotation of the knocking cam 161 can drive the rotation of the output shaft 163, the rotation of the driving ring plate 164 is driven by the second synchronous chain 165, the synchronous rotation of the driving shaft 169 is driven by the synchronous block, and the synchronous rotation of the driving shaft 169 can drive the synchronous rotation of the reciprocating rod 168 through the first synchronous chain 167. The output shaft 163 of the knocking motor 162 rotates, and the reciprocating rod 168 also synchronously and continuously rotates. Under the action of the first reciprocating thread 1681, the limiting slide block 16 moves from one end of the limiting groove 154 to the other end, so that the knocking cam 161 vibrates and knocks synchronously with the movement of the limiting slide block 16;

[0061] When the limiting slide block 16 moves to one end of the limiting groove 154, the limiting slide block 16 extrudes the driving rack 178, drives the driving gear 176 to rotate through the meshing of the gear, and then drives the adjusting shaft 174 on the same side to synchronously rotate through the center shaft 177 and the third synchronous chain 175. The synchronous rotation of the adjusting shaft 174 makes the adjusting shaft 174 elongate under the action of the second reciprocating thread 172, so that one end of the knocking plate 15 is automatically displaced by a set amount. When the limiting slide block 16 moves towards the other end and separates from the driving rack 178, the return spring 1783 can drive the driving rack 178 to automatically restore to the initial position, and since the center shaft 177 is connected with the driving gear 176 in one-way rotation, the adjusting shaft 174 will not be rotated;

[0062] When the limiting slide block 16 moves to the other end of the limiting groove 154, the limiting slide block 16 will automatically extrude the second hydraulic telescopic rod 1592, drive the first hydraulic telescopic rod 1593 to automatically elongate through the hydraulic transmission of the connecting hose 1591, so that the driving rack 178 moves, thereby driving the adjusting shaft 174 on the other end to synchronously rotate, so that the other end of the knocking plate 15 can automatically move by a set displacement. When the limiting slide block 16 separates, the return spring 1783 can automatically drive the corresponding driving rack 178 to restore to the initial position, and since the center shaft 177 is connected with the driving gear 176 in one-way rotation, the adjusting shaft 174 will not be rotated, waiting for the next extrusion;

[0063] In this way, the knocking cam 161 can knock and vibrate the side of the discharge hopper 12 in all directions, so that the broken material is more completely and efficiently broken.
