DETAILED DESCRIPTION

[0034] See also Figure 1-Figure 11 In an embodiment of the present invention, a crushing device for processing inorganic grouting materials includes a shell 1, a feed hopper 2 is fixedly arranged on the top of the shell 1, the feed hopper 2 is connected to the shell 1, a crushing roller 3 is rotatably arranged at the bottom end of the feed hopper 2, and a plurality of crushing rollers 3 are arranged in a horizontal array at the bottom end of the feed hopper 2, a screening plate 4 is arranged in the shell 1, a fixed seat 91 is arranged below the screening plate 4, the fixed seat 91 is fixedly connected to the inner wall of the shell 1, a motor is fixedly arranged at the top center of the fixed seat 91, a driving shaft 9 is fixedly arranged at the top output end of the motor, and the top sliding end of the driving shaft 9 The driving shaft 9 is driven through the side wall of the screening plate 4 and extends to the top of the screening plate 4. A grinding roller 6 is rotatably arranged on the outer periphery of the top end of the driving shaft 9. Preferably, two groups of grinding rollers 6 are arranged in a circular array along the center of the driving shaft 9, and the grinding rollers 6 are arranged above the screening plate 4. An auxiliary component is arranged below the grinding roller 6. The auxiliary component is slidably fitted with the top of the screening plate 4. A transmission component is arranged at the end of the grinding roller 6 away from the driving shaft 9. The transmission component and the auxiliary component are matched for transmission. When the transmission component rotates, the transmission component drives the auxiliary component to reciprocate vertically relative to the grinding roller 6.

[0035] Preferably, the fixed seat 91 includes a disc and an extension plate, the extension plate is fixedly arranged on the periphery of the disc, and the extension plates are arranged in a cross-shaped array on the periphery of the disc, one end of the extension plate away from the disc is fixedly connected to the inner wall of the shell 1, the motor is fixedly installed on the disc, and a discharge port is provided at the bottom of the shell 1.

[0036] During specific use, in the initial state where the inorganic grouting material is not crushed, the screening plate 4 is located near the top of the driving shaft 9 under the action of the spring. When the inorganic grouting material needs to be crushed, the crushing roller 3 is started to rotate, and then the inorganic grouting material to be processed is added from the feed hopper 2. Then the crushing roller 3 rotates to crush the inorganic grouting material in the feed hopper 2. The crushed inorganic grouting material falls onto the screening plate 4 in the shell 1, and then the crushed material is screened under the action of the screening plate 4. After the inorganic grouting material is crushed by the crushing roller 3, it is inevitable that there are some larger particles that cannot pass through the screening plate 4. Therefore, at this time, the motor is started to make The driving shaft 9 rotates, and the rotation of the driving shaft 9 causes the grinding roller 6 to rotate. The rotation of the grinding roller 6 drives the auxiliary components to rotate around the driving shaft 9. During this process, the auxiliary components scoop up some larger particles of inorganic grouting materials on the screening plate 4 and convey them to the grinding roller 6. Then, the larger particles of inorganic grouting materials are further crushed and ground through the cooperation of the grinding roller 6 and the auxiliary components, thereby avoiding the situation where the grinding roller 6 directly crushes the inorganic grouting materials with the screening plate 4 as the plane, which may cause some inorganic grouting materials to be stuck in the sieve holes of the screening plate 4, causing the screening plate 4 to be blocked. The inorganic grouting materials screened by the screening plate 4 can fall to the discharge port at the bottom of the shell 1 and be discharged.

[0037] See also Figure 2-Figure 3 Preferably, a bevel gear 15 is fixedly provided at one end of the grinding roller 6 away from the driving shaft 9, and a transmission groove adapted to the bevel gear 15 is provided on the inner wall of the housing 1, and a tooth groove 5 that is transmission-engaged with the bevel gear 15 is provided in the transmission groove, and the tooth groove 5 is arranged on the lower end surface of the transmission groove. When used in this way, when the starting motor drives the driving shaft 9 to rotate clockwise, the rotation of the driving shaft 9 drives the grinding roller 6 to rotate clockwise around the driving shaft 9, and the rotation of the grinding roller 6 drives the bevel gear 15 to rotate clockwise around the driving shaft 9. The rotation of the bevel gear 15 realizes counterclockwise rotation through the cooperation with the tooth groove 5, and the rotation of the bevel gear 15 drives the grinding roller 6 to rotate. The rotation of the grinding roller 6 grinds and crushes the larger particles of inorganic grouting material on the screening plate 4.

[0038] See also Figure 2-Figure 6The support plate 14 is sleeved on the outer periphery of the two ends of the grinding roller 6, and the bottom end of the support plate 14 away from the bottom plate 13 is rotatably connected with a shovel plate 7, and the end of the shovel plate 7 away from the support plate 14 is slidably fitted with the top of the screening plate 4, and a torsion spring is provided at the rotation connection between the shovel plate 7 and the support plate 14. The torsion spring is provided so that the end of the shovel plate 7 away from the support plate 14 always keeps fitting with the top of the screening plate 4, and the height of the end of the shovel plate 7 close to the support plate 14 is always higher than the top height of the bottom plate 13, and the end of the shovel plate 7 away from the support plate 14 is provided with an inclined surface, and the shovel plate 7 is installed in front of the rotation direction of the grinding roller 6 revolving around the driving shaft 9. In this way, when in use, when the driving shaft 9 rotates clockwise to drive When the grinding roller 6 rotates clockwise, the grinding roller 6 rotates counterclockwise synchronously with the cooperation of the bevel gear 15 and the tooth groove 5, and when the grinding roller 6 revolves clockwise around the driving shaft 9, it synchronously drives the support plate 14 and the shovel plate 7 to revolve clockwise around the driving shaft 9. Since the end of the shovel plate 7 away from the support plate 14 is in contact with the top of the screening plate 4, and the shovel plate 7 is also provided with an inclined surface, the shovel plate 7 will shovel up the large particles on the screening plate 4 through the inclined surface during the revolution around the driving shaft 9, and then under the action of the rotation of the shovel plate 7, the material on the shovel plate 7 will move to the bottom plate 13, and then under the action of the self-rotation of the grinding roller 6, the inorganic grouting material is re-grinded and crushed, thereby improving the crushing and grinding effect of the inorganic grouting material, and avoiding the problem of clogging of the screening plate 4 when the grinding roller 6 directly grinds the material through the screening plate 4 as a platform.

[0039] Further, preferably, an arc-shaped matching portion 22 adapted to the grinding roller 6 is provided at the top of one end of the bottom plate 13 away from the shovel plate 7, so that when in use, the material on the bottom plate 13 can be ground and crushed to a maximum extent.

[0040] Preferably, the top periphery of the driving shaft 9 is rotatably connected to a collar, and the periphery of the collar is fixedly connected to a connecting rod fixedly connected to the support plate 14. The support plate 14 is limited by the cooperation of the collar and the connecting rod, thereby avoiding possible rotation of the support plate 14. The collar and the connecting rod are not shown in the figure.

[0041] See also Figure 5-Figure 7Preferably, the transmission assembly includes a cam 10; the cam 10 is fixedly arranged on the periphery of one end of the driving shaft 9 close to the bevel gear 15, a lifting column 20 is fixedly arranged at the center of one side of the cam 10 close to the driving shaft 9, a lifting rod 11 is slidably fitted above the lifting column 20, a fixing plate 16 is fixedly arranged at the bottom of the lifting rod 11 symmetrically along the center, the bottom end of the fixing plate 16 is fixedly connected to the bottom plate 13, the lifting rod 11 and the fixing plate 16 are both slidably fitted with one side of the support plate 14 close to the cam 10, the width of the fixing plate 16 is equal to half the width of the lifting rod 11, and the fixing plate 16 is arranged on one side of the lifting rod 11 close to the driving shaft 9 On the other side, two groups of fixed plates 16 are arranged on both sides of the grinding roller 6, and the lifting column 20 is arranged on the side of the lifting rod 11 close to the cam 10, so that when the lifting column 20 rotates, there will be no conflict with the fixed plate 16. In addition, the width of the lifting rod 11 is larger than the diameter of the rotation track of the lifting column 20, and the support plate 14 is provided with a notch for the base plate 13 to move vertically, and the end of the base plate 13 is provided with a protrusion slidably connected to the notch, and the bottom of the fixed plate 16 is fixedly connected to the protrusion, so that when in use, when the fixed plate 16 moves downward, the protrusion will drive the base plate 13 to move within the restriction of the notch.

[0042] When in use, when the grinding roller 6 rotates, the cam 10 is driven to rotate, and the rotation of the cam 10 drives the lifting column 20 to rotate, and the rotation of the lifting column 20 drives the lifting rod 11 to reciprocate in the vertical direction. The movement of the lifting rod 11 drives the bottom plate 13 to reciprocate in the vertical direction relative to the grinding roller 6 through the fixed plate 16. When the cam 10 rotates to a position close to the feed hopper 2, the lifting column 20 drives the lifting rod 11 to move upward to the maximum distance, and then drives the bottom plate 13 to move through the fixed plate 16 to minimize the distance between the bottom plate and the grinding roller 6. The top height of 13 is still maintained lower than the height of one end of the shovel plate 7 close to the support plate 14, and then the cam 10 continues to rotate. When the cam 10 rotates close to the position of the screening plate 4, the distance between the bottom plate 13 and the grinding roller 6 is the largest, and this reciprocating process is repeated. When the distance between the bottom plate 13 and the grinding roller 6 is the largest, the inorganic grouting material particles scooped up by the shovel plate 7 are transported to the bottom plate 13, and then the bottom plate 13 moves relative to the grinding roller 6 until the minimum distance is reached. In this process, the grinding roller 6 is cooperated to achieve a more thorough grinding and crushing of the material on the bottom plate 13, thereby further improving the quality of the grinding and crushing.

[0043] See also Figure 4Preferably, a slide bar 92 is fixedly provided at the bottom of the screening plate 4, and the end of the slide bar 92 away from the screening plate 4 slides through the side wall of the fixed seat 91, and a spring is sleeved on the outer periphery of the slide bar 92, and the end of the slide bar 92 away from the screening plate 4 slides through the side wall of the extension plate, and the spring on the outer periphery of the slide bar 92 is arranged between the extension plate and the screening plate 4. In this way, when in use, when the cam 10 rotates and approaches the screening plate 4, the cam 10 will push the screening plate 4 to move downward, so that the slide bar 92 moves downward, thereby causing the spring to contract under force, and then when the cam 10 rotates and separates from the screening plate 4, the screening plate 4 moves upward and resets under the action of the spring, and so on and so forth, thereby achieving the vibration effect of the screening plate 4, thereby further improving the screening efficiency of the screening plate 4 for the material after grinding and crushing.

[0044] See also Figure 8-Figure 10 Preferably, a positioning groove 71 is provided at the bottom of the shovel plate 7, and the positioning groove 71 is vertically arranged with one side of the shovel plate 7 close to the screening plate 4, and a first positioning rod 18 is movably connected in the positioning groove 71, and a ring groove slidably connected to the bottom end of the first positioning rod 18 is provided at the top of the screening plate 4, and a ring plate 8 is slidably adapted at the top of the ring groove, and the first positioning rod 18 is slidably connected to the ring plate 8, and the first positioning rod 18 includes a first round rod and a base, and the first round rod and the base are fixedly installed and connected, and a second round rod is fixedly provided at the top of the first round rod, and the second round rod and the first round rod are vertically arranged, and the second round rod is movably connected with the positioning groove 71, that is, the second round rod can rotate and slide in the positioning groove 71, and the base is slidably connected to the annular groove, and the bottom end of the first round rod passes through the side wall of the annular plate 8 and extends into the annular groove.

[0045] When in use, in the initial state, the end of the shovel plate 7 away from the support plate 14 is in contact with the top of the screen plate 4, and the second round rod in the first positioning rod 18 is in the positioning groove 71 close to the end of the support plate 14; when the cam 10 rotates to cause the screen plate 4 to move downward, the screen plate 4 moves downward, driving the first positioning rod 18 and the annular plate 8 to move downward. Since a torsion spring is provided between the shovel plate 7 and the support plate 14 and the length of the first positioning rod 18 is fixed, when the screen plate 4 moves downward, the first positioning rod 18 will move downward synchronously. In this process, the top of the first positioning rod 18 It will slide toward the end of the positioning groove 71 away from the support plate 14, thereby making the inclination angle of the shovel plate 7 relative to the screening plate 4 gradually increase, but the end of the shovel plate 7 away from the support plate 14 always remains in contact with the top of the screening plate 4, thereby ensuring the effect of the shovel plate 7 on scooping up the material on the screening plate 4, and during the rotation of the first positioning rod 18, the first positioning rod 18 will drive the annular plate 8 to rotate in the annular groove. Through the setting of the annular plate 8, the problem of material particles falling on the screening plate 4 falling into the annular groove and blocking the annular groove, resulting in the first positioning rod 18 being unable to rotate in the annular groove, is avoided.

[0046] See also Figure 5 , Figure 6 , Figure 8 The conveyor belt 12 is preferably provided between the shovel plate 7 and the bottom plate 13, and two sets of driven shafts 121 are symmetrically provided on both sides of the conveyor belt 12 along the center. The two sets of driven shafts 121 are respectively arranged at positions close to the shovel plate 7 and the bottom plate 13, and the driven shaft 121 is rotatably connected with the support plate 14. The top height of the conveyor belt 12 is lower than the height of one end of the shovel plate 7 close to the support plate 14, and the height of one end of the conveyor belt 12 away from the support plate 14 is higher than the top height after the bottom plate 13 moves upward. In this way, when in use, after the material on the shovel plate 7 is scooped up, the material is subsequently transported to the conveyor belt 12. At this time, when the conveyor belt 12 rotates clockwise, that is, the rotation direction of the conveyor belt 12 is opposite to the rotation direction of the grinding roller 6, the conveyor belt 12 can transport the material on it to the bottom plate 13 by rotation, thereby avoiding the situation that the material between the shovel plate 7 and the bottom plate 13 cannot be transported to the grinding roller 6 for grinding and crushing in time due to too much material, resulting in the accumulation of a large amount of material, causing part of the material to pass over the grinding roller 6 and cannot be effectively ground and crushed.

[0047] See also Figure 8 Preferably, a transmission cavity 19 is provided in the side wall of the support plate 14, and a first transmission wheel 21 and a second transmission wheel 23 are rotatably provided in the transmission cavity 19. The first transmission wheel 21 and the second transmission wheel 23 are connected by belt transmission, and the periphery of the first transmission wheel 21 is tightly fitted with the periphery of the grinding roller 6. The second transmission wheel 23 is fixedly provided on the periphery of a group of driven shafts 121. When in use, when the grinding roller 6 realizes counterclockwise rotation through the cooperation of the bevel gear 15 and the tooth groove 5, the rotation of the grinding roller 6 drives the first transmission wheel 21 to rotate clockwise, and then the first transmission wheel 21 drives the second transmission wheel 23 to realize clockwise rotation through the belt, and then drives the second transmission wheel 23 to drive the driven shaft 121 to rotate, thereby realizing the clockwise rotation of the conveyor belt 12 and transporting the material particles thereon to the bottom plate 13.

The second positioning rod has the same structure as the first positioning rod 18, and the second positioning rod is slidably connected to the annular groove, and the second positioning rod is slidably connected to the annular plate 8. The arc scraper 17 is arranged in an arc structure, and the end of the arc scraper 17 away from the driving shaft 9 extends to the end of the shovel plate 7 away from the support plate 14, and the end of the arc scraper 17 away from the driving shaft 9 corresponds to the end of the shovel plate 7 close to the driving shaft 9. When in use, when the driving shaft 9 rotates, the arc scraper 17 is driven to rotate. The rotating arc scraper 17 can guide the inorganic grouting material particles on the screen plate 4 between the shovel plate 7 and the driving shaft 9, and guide the inorganic grouting material particles to the position corresponding to the end of the shovel plate 7 away from the support plate 14, thereby avoiding the problem that the inorganic grouting material particles close to the driving shaft 9 cannot be ground and crushed by the grinding roller 6; and when the screen plate 4 moves downward, the arc scraper 17 moves with the screen plate 4, so as to always maintain a state of being in contact with the screen plate 4, and keep guiding the inorganic grouting material particles between the shovel plate 7 and the driving shaft 9.
