The invention discloses a stone crushing device, which has the following working principle: through the conveyer belt (can carry the device of stone to be provided with height sensor or vision sensor in the side direction of conveyer belt for detect the size of stone, especially detect whether the size of stone exceeds standard, be greater than the distance between two stripper plates 109, provide the basis for centrifugal air pump 208's start-up opportunity), carry the stone to the position between two dust guard 108 (the top in the middle of two stripper plates 109), fall into between two stripper plates 109 with the stone, start driving motor 218 (driving motor 218's start-up mode has two) this moment, forward and backward direction's start (forward rotation back is gone back, the circulation goes on), driving motor 218's output shaft can drive sun gear 220 rotation, sun gear 220 rotates and can drive outer lane gear 222 through planetary gear 221 rotation, outer lane gear 222 rotates and can drive driving fluted disc 211 rotation (drive one of them driving fluted disc 211 rotation, because two driving fluted disc 211 mesh mutually, so two driving fluted disc 211 simultaneously rotate). The driving fluted disc 211 rotates to drive the driving gear 206 to rotate, the driving gear 206 rotates to drive the driving rack 205 to move (the driving rack 205 is slidably mounted on the outer surface of the cylinder barrel 201), the driving rack 205 moves to drive the driving column 204 to move, the driving column 204 moves to drive the piston 203 and the push-pull column 202 to move (as the pressure relief opening 2011 is formed, the pressure can be released, the pressure at the three-way nozzle 2012 can flow out through the gap of the impeller in the centrifugal air pump 208 or drive the impeller of the centrifugal air pump 208 to rotate), the push-pull beam 113 is driven to move by the movement of the push-pull column 202, the push-pull beam 113 drives the two driving push-pull rods 111 to move relatively through the two movable connecting rods 112, so that the two pressing plates 109 can move relatively, when the two pressing plates 109 are close to each other, the falling stone blocks are crushed (a plurality of broken stone strips are arranged on the pressing plates 109 to reduce the contact area with the stone surfaces, so that the stone blocks are easy to crush), and the dust-proof plates 108 are fixedly arranged on the pressing plates 109 to prevent the pressing plates 109 from being blocked.

In addition, the other starting mode of the driving motor 218 is to control the driving motor 218 to rotate in one direction only (that is, the push-pull column 202 is far away from the side shielding plate 114, so that the two extrusion plates 109 are close to each other), intermittently start the centrifugal air pump 208, when the centrifugal air pump 208 starts, the centrifugal air pump 208 can press into the cylinder barrel 201 through the three-way nozzle 2012, and simultaneously press into the pneumatic telescopic rod 210 through the air pipe 209, because the resistance at the push-pull column 202 is larger, the telescopic rod of the pneumatic telescopic rod 210 is firstly extended, so as to move against the limiting sliding rod 216 (overcome the elastic force of the spring 217), so that the clamping limiting frame 214 is in separated engagement with the planetary gear plate 219, at this time, the planetary gear plate 219 is in a free rotation state, at this time, the push-pull column 202 is extended, that is, the two extrusion plates 109 are controlled to be far away from each other, this stroke reduces the time of a single stroke of the extrusion plate 109 because it does not need to extrude the stone, and reduces the energy consumed by the constant operation of the drive motor 218 because the centrifugal air pump 208 is low in power, the same drive gear 206 and the drive fluted disc 211 rotate because the movement of the push-pull column 202 also moves the drive column 204 and the drive rack 205, the power of the drive motor 218 is mainly used to extrude the stone, a larger power model is needed, the passive rotation of the output shaft of the drive motor 218 needs to overcome a larger torque, and the planetary gear disc 219 is in a free rotation state at this time, so that the power of the outer ring gear 222 cannot be transmitted to the output shaft of the drive motor 218, but is transmitted to the planetary gear disc 219, thereby reducing the energy required to move the push-pull column 202. When a large stone is detected (in order to shorten the time, the smaller the distance the squeeze plates 109 are moved each time, the better the distance the squeeze plates 109 are moved each time is freely adjusted according to the size of the stone), the centrifugal air pump 208 is rapidly controlled to be started, and at this time, the two squeeze plates 109 are rapidly moved away from each other, so that stones of a larger size fall between the two squeeze plates 109.

According to the size of the stone to be crushed, the adjusting motor 105 is controlled, the output shaft of the adjusting motor 105 drives the screw rod 104 to rotate, the screw rod 104 rotates to drive the adjusting plate 107 to slide on the adjusting plate sliding frame 103 through the adjusting plate bracket 106, the gap between the bottom edge of the adjusting plate 107 and the sliding plate 102 is adjusted, the crushed stone can slide out of between the two extruding plates 109, if the size of the crushed stone still cannot pass, the crushed stone can be extruded between the two extruding plates 109 continuously until the size is qualified, and the crushed stone can pass through the gap between the adjusting plate 107 and the sliding plate 102.
