DETAILED DESCRIPTION

[0033] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the rectangular plate 21 moves, the cooperation between the through hole 23 and the fixing rod 25 prevents the rectangular plate 21 from being skewed when moving. The rectangular plate 21 moves through the rectangular groove 22 to drive the driven slider 26 to move. The driven slider 26 moves through the support rod 27 to enable the pin 28 to move inside the screening groove 12. At the same time, the cooperation between the support rod 27 and the arc groove 3 makes the moving trajectory of the pin 28 the same as the arc shape of the screening groove 12, so that the pin 28 always moves inside the screening groove 12, thereby preventing the screening groove 12 from being blocked.

[0039] Among them, in order to achieve the purpose of crushing the gravel entering the crushing shell 2, the present device adopts the following technical scheme: one side of the protective shell 1 is fixedly arranged on the motor 7, the output end of the motor 7 is fixedly connected to one end of the main transmission shaft 8, and the two ends of the main transmission shaft 8 respectively penetrate the two side walls of the protective shell 1 and are connected to the two side walls of the protective shell 1 through bearings. The breaker 10 is sleeved on the outside of the crushing roller 9 and is connected to the crushing roller 9 through bearings. The motor 7 is started to rotate clockwise, and the motor 7 rotates the crushing roller 9 through the main transmission shaft 8. When the crushing roller 9 rotates, it drives the breaker 10 to rotate, so that the multiple breaker hammers 10 outside the crushing roller 9 are expanded by the centrifugal force during rotation, and the rotating breaker hammers 10 hammer the synthetic stone raw materials input to crush the synthetic stone raw materials.

[0040] Among them, in order to achieve the purpose of preventing dust and gravel from accumulating at the end of the screening slot, the device is implemented by the following technical solutions: The device is implemented by the following technical solutions: An anti-blocking auxiliary component is arranged at the bottom of the screening plate 11, and the anti-blocking auxiliary component includes two transmission shafts 32 symmetrically arranged at the bottom of the screening plate 11, and both ends of the transmission shaft 32 pass through the crushing shell 2 and are fixedly connected with a baffle 33, and a plurality of hook plates 34 distributed in an array are fixedly installed on the transmission shaft 32, and the end of the hook plate 34 extends to the inner end of the screening slot 12, and an extrusion plate 35 is fixedly connected to the side of the rectangular plate 21, and the end of the extrusion plate 35 abuts against the baffle 33, and a coil spring 36 is sleeved on the outer side of the moving shaft 32, and the other end of the coil spring 36 is fixedly installed on the crushing shell 2, and the connection between the transmission shaft 32 and the crushing shell 2 is movably connected through a bearing;

[0041] The device is provided with an anti-blocking auxiliary component. In actual use, when the rectangular plate 21 moves back and forth, driving the pin 28 to move left and right to clean the screening slot 12, the dust, gravel and other debris in the screening slot 12 may be squeezed by the pin 28 at the end of the screening slot 12 and stuck and accumulated more and more, making it difficult to clean, so that the pin cannot effectively clean the screening slot 12. The squeezing plate 35 of the anti-blocking auxiliary component will move with the rectangular block 21, so that when the rectangular block 21 moves to one side, it will push the squeezing plate 35 The drive shaft 32 rotates, thereby causing the hook plate 34 to rotate. At this time, the hook plate 34 is separated from the screening slot 12, and the pin 28 moves normally to the end of the screening slot 12 for cleaning. When the rectangular block 21 moves back, under the elastic force of the coil spring 36, the drive shaft 32 will rotate rapidly, driving the hook plate 34 to rotate. The hook plate 34 can knock and clean the foreign matter stuck in the end of the screening slot 12 to prevent foreign matter from being stuck in the end of the screening slot. This reciprocating process, the pin 28 and the hook plate 34 cooperate with each other to ensure that there is no foreign matter stuck in the screening slot.

[0042] The use process of the present invention is as follows: when using the present invention, an external power supply is connected. When the synthetic stone raw material needs to be crushed, the synthetic stone raw material is put into the crushing shell 2 through the anti-bounce iron chain 6, and the motor 7 is started to rotate clockwise. The motor 7 rotates the crushing roller 9 through the main transmission shaft 8. When the crushing roller 9 rotates, it drives the crushing hammer 10 to rotate, so that the multiple crushing hammers 10 outside the crushing roller 9 are expanded by the centrifugal force during rotation. The rotating crushing hammer 10 hammers the put-in synthetic stone raw material to crush the synthetic stone raw material. Since the stones are of different sizes during crushing, the stones of suitable sizes are discharged from the outside of the crushing shell 2 through the screening slot 12 at the bottom of the screening plate 11 after crushing, and the stones of other sizes are on the screening plate 11 and are hammered and crushed again by the subsequent crushing hammer 10, so that only the stones of suitable sizes can be discharged from the outside of the crushing shell 2, so that there is no need to screen the crushed stones of different sizes and then put them in again, reducing the operation steps, thereby reducing the time required for crushing and improving the crushing efficiency. Since the crushed stones are not completely discharged, in order to prevent the screening slot 12 from being blocked, the main transmission shaft 8 passes through the screening slot 12 when rotating. The cooperation of the main pulley 13, the belt 14, and the slave pulley 15 causes the secondary transmission shaft 16 to rotate. The rotation of the secondary transmission shaft 16 causes the swing arm 18 to rotate through the transmission rod 17. The rotation of the swing arm 18 drives the driving slider 20 to rotate through the connecting column 19. The driving slider 20 rotates and cooperates with the rectangular groove 22 to make the rectangular plate 21 reciprocate left and right. When the rectangular plate 21 moves, the cooperation between the through hole 23 and the fixing rod 25 prevents the rectangular plate 21 from being skewed when moving. The rectangular plate 21 moves through the rectangular groove 22 to drive the driven slider 26 to move. The driven slider 2 6 moves through the support rod 27 so that the pin 28 moves inside the screening slot 12. At the same time, the support rod 27 cooperates with the arc groove 3 to make the moving trajectory of the pin 28 the same as the arc shape of the screening slot 12, so that the pin 28 always moves inside the screening slot 12, thereby preventing the screening slot 12 from being blocked, so that the screening slot 12 can stably discharge suitable stones for crushing, ensuring the stable operation of the device, and at the same time, in order to prevent the crushed stones from jumping out of the inlet of the crushing shell 2, the anti-bounce plate 5 and the anti-bounce chain 6 are used to prevent the stones from jumping out.

[0043] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention shall fall within the scope of protection claimed by the present invention.
