Through the rotation of the connecting rod 16, as shown in fig. 5 and 4, under the action of the second bevel gear transmission mechanism 18, the first rotating shaft 17 and the second rotating shaft 19 are driven to rotate, and the rotation of the second rotating shaft 19 drives the slider 20 to revolve around the first rotating shaft 17, because the sliding fit relationship between the first sliding groove 23 on the swinging plate 22 and the slider 20 and the center of the swinging plate 22 is the second rotating shaft 21, when the slider 20 rotates, the swinging plate 22 and the second rotating shaft 21 will swing reciprocally, and the slider 20 will slide in the first sliding groove 23 while revolving, so that the distance from the slider 20 to the second rotating shaft 21 is gradually shortened from the state shown in fig. 4, and therefore, the rotating force acting on the first sliding groove 23 changes in displacement, and when the slider 20 is closer to the second rotating shaft 21, the rotating speed of the second rotating shaft 21 is faster, and therefore, through the rotation of the first rotating shaft 17, the second rotating shaft 21 can be driven to do reciprocating variable speed swing.
The incomplete gear 37 can be driven to rotate by the rotation of the second rotating shaft 21, the incomplete gear 37 can be driven to rotate through the meshing relationship and the limitation of the second sliding groove 25 on the displacement direction of the bearing block 24, so that the rack bar row 35 can reciprocate vertically and is connected with the lower part of the transmission connection of the sliding bar 34 through the transmission of the sliding bar 34, as shown in figure 3, a vertical acting force is given to the sleeve 7, as the sliding fit relationship between the sleeve 7 and the sliding bar 34, the sleeve 7 can move transversely, when the transmission plate 6 is driven to move vertically, as the sliding fit relationship between the two sliding columns 5 and the guide groove 4 is realized, and the two sliding columns 5 are both positioned at the leftmost sides of different wave bands in the guide groove 4 as shown in figure 3, so that the two sliding columns 5 can move synchronously, as the transmission plate 6 can reciprocate through the rack bar row 35, the reciprocating vertical movement can be realized, and as the guide groove 4 is wavy, the two sliding columns 5 can move synchronously at the same positions of different wave bands of the guide groove 4, make driving plate 6 can carry out reciprocating lateral shifting, driving plate 6 drives and strikes ball 8 reciprocal sideslip and can strike processing case 1's surface, and driving plate 6 drives the reciprocal vertical movement who strikes ball 8, can drive and strike ball 8 and strike processing case 1 surface regional striking by a wide margin, makes it vibrate, and this region can cover the work area who smashes grinding roller 10 and correspond, and quick striking helps improving the unloading of raw materials and the efficiency of unloading.
As shown in fig. 4, when the slide block 20 rotates clockwise, the striking ball 8 moves downward and then moves upward through the transmission relationship, which is the first stage, and at the same time, the swinging speed of the second rotating shaft 21 is increased, so that the speed of the sleeve 7 in the first stage is increased, and therefore the striking speed of the striking ball 8 is also increased, when the slide block 20 rotates clockwise 180 degrees, the rotating speed of the second rotating shaft 21 is increased gradually and then becomes fastest, the first stage is ended, and the striking ball 8 is reset upward after moving downward and then is positioned again as shown in fig. 2, the gradually increased striking speed can strike and vibrate the lower part of the working area of the grinding and milling roller 10, because the lower part of the working area of the grinding and milling roller 10 is positioned in the concentrated grinding area, which is the vertical area of the grinding and milling roller 10 in fig. 2, the concentrated grinding area is positioned, and therefore more raw materials can adhere to the inner wall of the corresponding processing box 1, thus helping to accelerate the discharge of the raw material by means of a quick knock; when the slide block 20 rotates 180 degrees clockwise and rotates clockwise for a circle to move, the knocking ball 8 moves upwards from the position shown in fig. 2 and then resets downwards, the knocking speed at the moment gradually changes from the fastest speed to the slowest speed, the irregular shaking frequency after knocking is favorable for improving the blanking efficiency of the raw materials, the knocking speed at the moment when the knocking ball 8 starts to move is still faster and knocks more quickly, the knocking is favorable for being transmitted into the processing box 1 through the inner wall of the working area above the grinding and grinding roller 10 to unload the raw materials attached to the inner wall of the processing box 1, and because the raw materials are easy to adhere to the inner wall of the processing box 1 during grinding and smashing work, if the raw materials are not processed, the amount of the obtained ground raw materials is reduced by one part, which is not beneficial to subsequent mixing processing, and simultaneously influences the service life of the processing box 1, this is waterproof can vibrate the raw materials on processing case 1 inner wall and unload, and the scope of unloading is great to and the speed of knocking is changing, and consequently the vibrations of knocking can effectually pierce through the inner wall of processing case 1 and shake the raw materials, has improved work efficiency.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
