Description

Technical Field

[0001] The invention relates to the field of crushers, and more particularly to a handheld crusher with anti-vibration function. Background Art

[0002] The working principles of different types of crushers are also completely different. Take the hammer crusher as an example: the hammer crusher mainly relies on impact energy to complete the material crushing operation. When the hammer crusher is working, the motor drives the rotor to rotate at high speed, and the material enters the crusher cavity evenly. The high-speed rotating hammer head impacts, shears and tears the material to be crushed. At the same time, the gravity of the material itself causes the material to rush from the high-speed rotating hammer head to the baffle and screen bars in the frame body. At the bottom of the rotor, there is a screen plate. The particle size smaller than the screen hole size in the crushed material is discharged through the screen plate, and the material larger than the screen hole size is retained on the screen plate and continues to be hit and ground by the hammer until it is crushed to the required discharge particle size and finally discharged from the machine through the screen plate.

[0003] When some existing handheld crushers are in operation, the vibrations they generate can easily cause hand fatigue to the workers, affecting work efficiency. During the crushing process, it is not convenient to intercept the flying gravel and it is not convenient to absorb the raised dust, posing a safety hazard to the health of the workers. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a hand-held crusher with an anti-seismic function. The crusher shell is pressed against the road surface by a protective tube. The upper end of the crusher shell is held by a hand-held support column to maintain the stability of the crusher shell. Due to the weight of the crusher shell, the protective tube is retracted upward by a first spring and a fixed rod until the lower end of the crushing pestle contacts the road surface. The striking piston is started to strike the crushing pestle downward. In the process of striking and crushing the road surface, the reaction force of the road surface on the crusher shell is buffered by the protective tube and the first spring to reduce the vibration amplitude of the crusher shell. As the crushing operation continues, the striking piston first makes the connecting column slide relative to the crushing pestle during the process of striking the crushing pestle. The heat generated during the sliding friction is conducted to the carbon dioxide elastic airbag through the heat conducting rod, so that the carbon dioxide elastic airbag expands. The expanded carbon dioxide elastic airbag cooperates with the connecting block and the connecting block to push the buffer tube downward, so that the lower end of the buffer tube contacts the road surface, and cooperates with the protective tube for double buffering, further reducing the vibration amplitude of the crusher shell, thereby reducing the fatigue of the staff's hands caused by vibration. The possibility of improving work efficiency is improved. In the process of sliding between the connecting column and the crushing pestle, the friction between the hard rubber layer and the fur layer generates static electricity on the surface of the fur layer, and the static electricity is conducted to the wool fiber through the static conduction metal wire. The heat generated in the friction between the hard rubber layer and the fur layer is conducted and reused in conjunction with the heat conduction rod, which reduces the vibration amplitude of the crusher shell and increases the service life of the fur layer. In the process of striking and crushing, the generated gravel is directly isolated and protected by the protective tube, reducing the possibility of gravel splashing everywhere, and then the wool fiber with static electricity is used to adsorb the generated dust, reducing the possibility of dust flying, and reducing the safety hazards caused to the staff. When the crusher shell is lifted by hand, the static electricity elimination metal block is lifted up with the crusher shell, and the lower end of the crushing pestle is first separated from the ground, and the lower end of the protective tube is still in contact with the ground. When the lower end of the protective tube reaches the critical point of separation from the ground, the static electricity elimination metal block contacts with the conduction ring, and the static electricity is conducted to the ground through the conduction ring in conjunction with the crushing pestle, so that the static electricity can be eliminated immediately when no adsorption operation is performed, reducing the possibility of static electricity causing safety hazards to personnel.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A hand-held crusher with anti-vibration function comprises a crusher shell, the inner cavity of the crusher shell is fixedly connected to a striking piston, the lower end of the crusher shell is slidably connected to a crushing pestle, the crushing pestle is located below the striking piston, the outer circumferential surface of the crusher shell is fixedly connected to a first fixing ring and a second fixing ring, the lower end of the first fixing ring is fixedly connected to a fixing rod, the lower end of the fixing rod passes through the second fixing ring, the outer circumferential surface of the fixing rod is fixedly connected to the second fixing ring, the lower end of the second fixing ring is fixedly connected to a first spring, the first spring is sleeved on the periphery of the fixing rod, and the lower end of the first spring is fixedly connected to A protective tube, which is sleeved on the lower end of the fixed rod, a sliding groove is bored on the upper end of the crushing pestle, a second spring is fixedly connected to the inner bottom end of the sliding groove, a connecting column is fixedly connected to the upper end of the second spring, and the connecting column forms a sliding connection with the crushing pestle through the sliding groove, a cavity is bored inside the crushing pestle, a heat-conducting rod is fixedly connected to the inner top end of the cavity, the upper end of the heat-conducting rod passes through the inner top end of the cavity and extends to the inner cavity of the sliding groove, a carbon dioxide elastic airbag is fixedly connected to the lower end of the elastic airbag, a connecting block is fixedly connected to the lower end of the elastic airbag, a pair of connecting blocks are fixedly connected to the outer circumferential surface of the connecting block, and the crushing pestle is provided with a plurality of connecting blocks. A pair of through grooves are chiseled on the outer circumference of the pestle, and one end of the pair of connecting blocks away from the connecting block passes through the through grooves. The outer end of the connecting block is fixedly connected with a buffer cylinder, and the buffer cylinder is sleeved on the periphery of the crushing pestle. The crusher shell is pressed against the road surface through the protective cylinder, and the upper end of the crusher shell is held by the support column to maintain the stability of the crusher shell. Due to the weight of the crusher shell, the protective cylinder is retracted upward by the first spring and the fixed rod until the lower end of the crushing pestle contacts the road surface, and the striking piston is started to strike the crushing pestle downward. In the process of striking and crushing the road surface, the reaction force of the road surface on the crusher shell is buffered by the protective cylinder and the first spring. The impact can reduce the vibration amplitude of the crusher shell. As the crushing operation continues, the striking piston will first make the connecting column slide relative to the crushing pestle during the striking of the crushing pestle. The heat generated during the sliding friction is conducted to the carbon dioxide elastic airbag through the heat conducting rod, causing the carbon dioxide elastic airbag to expand. The expanded carbon dioxide elastic airbag cooperates with the connecting block and the connecting block to push the buffer cylinder downward, so that the lower end of the buffer cylinder contacts the road surface, and cooperates with the protective cylinder for double buffering, which further reduces the vibration amplitude of the crusher shell, thereby reducing the possibility of hand fatigue of the staff due to vibration and improving work efficiency.

[0007] Furthermore, a hard rubber layer is fixedly connected to the circumferential surface of the connecting column, a fur layer is fixedly connected to the inner wall of the sliding groove, an end of the fur layer close to the sliding groove is fixedly connected to an electrostatic conductive metal wire, the outer end of the electrostatic conductive metal wire passes through the sliding groove and extends to the inner cavity of the protective tube, the outer surface of the electrostatic conductive metal wire located in the inner cavity of the protective tube is fixedly connected to wool fibers, the outer end of the electrostatic conductive metal wire is fixedly connected to a static eliminating metal block, the inner cavity of the protective tube is fixedly connected to a conduction ring, the conduction ring cooperates with the inner bottom end of the protective tube to form a protective cavity, the inner wall of the protective cavity is fixedly connected to an insulating layer, the outer circumferential surface of the protective tube is cut with an adsorption groove, the adsorption groove is connected to the inner cavity of the protective tube, in the process of sliding of the connecting column relative to the crushing pestle, static electricity is generated on the surface of the fur layer due to the mutual friction between the hard rubber layer and the fur layer, and the static electricity is conducted to the wool fibers through the electrostatic conductive metal wire. The heat generated during the friction between the hard rubber layer and the fur layer is conducted and reused in conjunction with the heat conducting rod, which reduces the vibration amplitude of the crusher shell and increases the service life of the fur layer. In the process of striking and crushing, the gravel generated is directly isolated and protected by the protective tube, reducing the possibility of gravel splashing everywhere, and then the wool fibers with static electricity are used to adsorb the generated dust, reducing the possibility of dust being raised, reducing the safety hazards caused to the staff. When the crusher shell is lifted by hand, the static electricity eliminating metal block is lifted up with the crusher shell, and the lower end of the crushing pestle is first separated from the ground, and the lower end of the protective tube is still in contact with the ground. When the lower end of the protective tube reaches the critical point of separation from the ground, the static electricity eliminating metal block contacts with the conductive ring, and the static electricity is conducted to the ground through the conductive ring in conjunction with the crushing pestle, so that the static electricity can be eliminated immediately when no adsorption operation is performed, reducing the possibility of static electricity causing safety hazards to personnel.

[0008] Furthermore, the inner wall of the sliding groove and the outer surface of the electrostatic conductive metal wire are both provided with an insulating coating. When electrostatic friction is generated, it will come into contact with the sliding groove at the first time, and the crushing pestle will come into contact with the ground. The insulating coating reduces the possibility of static electricity directly grounding. The electrostatic conductive metal wire and the crushing pestle are fixedly connected, and the insulating coating is used again to further reduce the possibility of static electricity directly grounding.

[0009] Furthermore, the vertical distance between the upper end of the connecting column and the upper end of the crushing pestle is smaller than the vertical distance between the lower end of the connecting column and the inner bottom end of the sliding groove, so that when the connecting column is fully retracted into the inner cavity of the sliding groove, the lower end of the connecting column still does not contact the inner bottom end of the sliding groove, so that while the connecting column and the crushing pestle slide, the striking piston can fully strike the upper end of the crushing pestle.

[0010] Furthermore, a pair of handles are fixedly connected to the upper end of the crusher shell, and the outer circumferential surfaces of the pair of handles are fixedly connected with a buffer silicone layer. The handles are convenient for workers to hold the support column crusher shell, and the buffer silicone layer further reduces the possibility of hand fatigue of workers due to vibration.

[0011] Furthermore, the outer circumferential surface of the connecting block is in contact with the inner wall of the cavity, and both the outer circumferential surface of the connecting block and the inner wall of the cavity are provided with a wear-resistant layer. The outer circumferential surface of the connecting block is in contact with the inner wall of the cavity so that the connecting block can be pressed downward by stably pushing the buffer cylinder, thereby improving the stability of the downward pressure of the buffer cylinder, and cooperating with the wear-resistant layer to reduce the wear of the connecting block and the inner wall of the cavity and improve the service life.

[0012] Furthermore, a protective net is fixedly connected to the inner wall of the adsorption tank, and the protective net is made of stainless steel. The protective net reduces the possibility of gravel passing through the adsorption tank and entering the interior of the protective cylinder.

[0013] Furthermore, a rubber insulating layer is fixedly connected to the inner wall of the conductive ring, and the rubber insulating layer is in contact with the wool fibers. During the crushing process, the wool fibers will shake along with the electrostatic conductive metal wire as the crusher shell is adjusted. The conductive ring is likely to be in contact with the wool fibers. The rubber insulating layer isolates the static electricity from the ground and improves the electrostatic adsorption effect on dust.

[0014] Furthermore, a rubber protective layer is fixedly connected to the upper end of the connecting column, and the striking piston only causes sliding friction between the connecting column and the crushing pestle during the striking process, and finally the lower end of the striking piston will fully strike the crushing pestle. The rubber protective layer not only does not affect the striking effect of the striking piston on the crushing pestle, but also reduces the rigid collision between the connecting column and the striking piston, thereby increasing the service life of the connecting column.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) In this scheme, the crusher shell is pressed against the road surface by a protective tube. The upper end of the crusher shell is held by a hand-held support column to maintain the stability of the crusher shell. Due to the weight of the crusher shell, the protective tube is retracted upward by the first spring and the fixed rod until the lower end of the crushing pestle contacts the road surface. The striking piston is started to strike the crushing pestle downward. In the process of striking and crushing the road surface, the reaction force of the road surface on the crusher shell is buffered by the protective tube and the first spring to reduce the vibration amplitude of the crusher shell. As the crushing operation continues, the striking piston first causes the connecting column to slide relative to the crushing pestle during the striking of the crushing pestle. The heat generated during the sliding friction is conducted to the carbon dioxide elastic airbag through the heat conducting rod, causing the carbon dioxide elastic airbag to expand. The expanded carbon dioxide elastic airbag cooperates with the connecting block and the connecting block to push the buffer tube downward, causing the lower end of the buffer tube to contact the road surface. The protective tube is used for double buffering, further reducing the vibration amplitude of the crusher shell, thereby reducing the possibility of hand fatigue of the staff due to vibration and improving work efficiency.

[0017] (2) A hard rubber layer is fixedly connected to the circumferential surface of the connecting column, a fur layer is fixedly connected to the inner wall of the sliding groove, an end of the fur layer close to the sliding groove is fixedly connected to an electrostatic conductive metal wire, the outer end of the electrostatic conductive metal wire passes through the sliding groove and extends to the inner cavity of the protective tube, the outer surface of the electrostatic conductive metal wire located in the inner cavity of the protective tube is fixedly connected to wool fibers, the outer end of the electrostatic conductive metal wire is fixedly connected to a static eliminating metal block, a conductive ring is fixedly connected to the inner cavity of the protective tube, the conductive ring cooperates with the inner bottom end of the protective tube to form a protective cavity, the inner wall of the protective cavity is fixedly connected to an insulating layer, an adsorption groove is cut on the outer circumferential surface of the protective tube, and the adsorption groove is connected to the inner cavity of the protective tube. When the connecting column slides relative to the crushing pestle, static electricity is generated on the surface of the fur layer due to the mutual friction between the hard rubber layer and the fur layer, and the static electricity is conducted to the wool fibers through the static conductive metal wire. The heat generated in the process is conducted and reused with the help of the heat conducting rod, which reduces the vibration amplitude of the crusher shell and increases the service life of the fur layer. In the process of striking and crushing, the gravel generated is directly isolated and protected by the protective tube, which reduces the possibility of gravel splashing everywhere. The wool fibers with static electricity are used to adsorb the generated dust, which reduces the possibility of dust being raised and reduces the safety hazards caused to the staff. When the crusher shell is lifted by hand, the static electricity eliminating metal block is lifted up with the crusher shell, and the lower end of the crushing pestle is first separated from the ground, and the lower end of the protective tube is still in contact with the ground. When the lower end of the protective tube reaches the critical point of separation from the ground, the static electricity eliminating metal block contacts the conductive ring, and the static electricity is conducted to the ground through the conductive ring and the crushing pestle, so that the static electricity can be eliminated immediately when no adsorption operation is performed, reducing the possibility of static electricity causing safety hazards to personnel.

[0018] (3) The inner wall of the sliding groove and the outer surface of the static conductive metal wire are both provided with an insulating coating. When static friction is generated, it will come into contact with the sliding groove at the first time, and the crushing pestle will come into contact with the ground. The insulating coating reduces the possibility of static electricity directly being connected to the ground. The static conductive metal wire and the crushing pestle are fixedly connected, and the insulating coating is used again to further reduce the possibility of static electricity directly being connected to the ground.

[0019] (4) The vertical distance between the upper end of the connecting column and the upper end of the crushing pestle is smaller than the vertical distance between the lower end of the connecting column and the inner bottom end of the sliding groove, so that when the connecting column is fully retracted into the inner cavity of the sliding groove, the lower end of the connecting column still does not contact the inner bottom end of the sliding groove, so that when the connecting column and the crushing pestle slide, the striking piston can fully strike the upper end of the crushing pestle.

[0020] (5) A pair of handles are fixedly connected to the upper end of the crusher shell, and the outer circumferential surfaces of the pair of handles are fixedly connected with a buffer silicone layer. The handles are convenient for workers to hold the crusher shell with a support column, and the buffer silicone layer can further reduce the possibility of hand fatigue of workers due to vibration.

[0021] (6) The outer circumferential surface of the connecting block is in contact with the inner wall of the cavity, and both the outer circumferential surface of the connecting block and the inner wall of the cavity are provided with a wear-resistant layer. The outer circumferential surface of the connecting block is in contact with the inner wall of the cavity, so that the connecting block can be pressed downward by stably pushing the buffer cylinder, thereby improving the stability of the downward pressure of the buffer cylinder. In combination with the wear-resistant layer, the wear of the connecting block and the inner wall of the cavity is reduced, thereby improving the service life.

[0022] (7) A protective net is fixedly connected to the inner wall of the adsorption tank. The protective net is made of stainless steel. The possibility of gravel passing through the adsorption tank and entering the interior of the protective tube is reduced through the protective net.

[0023] (8) The inner wall of the conductive ring is fixedly connected with a rubber insulating layer, which is in contact with the wool fibers. During the crushing process, the wool fibers will shake along with the electrostatic conductive wire as the crusher shell is adjusted. The conductive ring is likely to be in contact with the wool fibers. The rubber insulating layer isolates the static electricity from the ground and improves the electrostatic adsorption effect on dust.

[0024] (9) The upper end of the connecting column is fixedly connected with a rubber protective layer. The striking piston only causes sliding friction between the connecting column and the crushing pestle during the striking process. Finally, the lower end of the striking piston will fully strike the crushing pestle. The rubber protective layer not only does not affect the striking effect of the striking piston on the crushing pestle, but also reduces the rigid collision between the connecting column and the striking piston, thereby increasing the service life of the connecting column.

One end of a pair of connecting blocks 35 away from the connecting block 34 passes through the through slot 36. The outer end of the connecting block 35 is fixedly connected with a buffer cylinder 37. The buffer cylinder 37 is sleeved on the periphery of the crushing pestle 3. The crusher shell 1 is pressed on the road surface through the protective cylinder 8. The upper end of the crusher shell 1 is held by the hand-held support column to maintain the stability of the crusher shell 1. The protective cylinder 8 is retracted upward by the first spring 7 and the fixed rod 6 due to the weight of the crusher shell 1 until the lower end of the crushing pestle 3 contacts the road surface, and the striking piston 2 is started to strike the crushing pestle 3 downward. In the process of striking and crushing the road surface, the reaction force of the road surface on the crusher shell 1 is buffered by the protective cylinder 8 and the first spring 7, thereby reducing the crusher shell The vibration amplitude of the body 1 is increased as the crushing operation is continuously carried out. When the striking piston 2 strikes the crushing pestle 3, the connecting column 11 first slides relative to the crushing pestle 3. The heat generated during the sliding friction is conducted to the carbon dioxide elastic airbag 33 through the heat conducting rod 32, causing the carbon dioxide elastic airbag 33 to expand. The expanded carbon dioxide elastic airbag 33 cooperates with the connecting block 34 and the connecting block 35 to push the buffer cylinder 37 downward, so that the lower end of the buffer cylinder 37 contacts the road surface, and cooperates with the protective cylinder 8 for double buffering, thereby further reducing the vibration amplitude of the crusher shell 1, thereby reducing the possibility of hand fatigue of the staff due to vibration and improving work efficiency.

The inner wall of the protective cavity 18 is fixedly connected with an insulating layer 19. An adsorption groove 20 is cut on the outer circumferential surface of the protective tube 8. The adsorption groove 20 is connected to the inner cavity of the protective tube 8. When the connecting column 11 slides relative to the crushing pestle 3, the hard rubber layer 12 and the fur layer 13 are rubbed against each other, so that static electricity is generated on the surface of the fur layer 13, and the static electricity is conducted to the wool fiber through the static conductive metal wire 14. 15.

In the process of striking and crushing, the generated gravel is directly isolated and protected by the protective tube 8, thereby reducing the possibility of gravel splashing everywhere. The wool fiber 15 with static electricity is then used to adsorb the generated dust, thereby reducing the possibility of dust being raised and reducing the safety hazard caused to the staff. When the crusher shell 1 is lifted by hand, the static electricity eliminating metal block 16 is lifted upward along with the crusher shell 1, and the lower end of the crushing pestle 3 is first separated from the ground, and the lower end of the protective tube 8 is still in contact with the ground. When the lower end of the protective tube 8 reaches the critical point of separation from the ground, the static electricity eliminating metal block 16 is in contact with the conductive ring 17, and the static electricity is conducted to the ground through the conductive ring 17 in conjunction with the crushing pestle 3, so that the static electricity can be immediately eliminated when no adsorption operation is performed, thereby reducing the possibility of static electricity causing safety hazards to personnel.

[0042] See also Figure 3-5The inner wall of the sliding groove 9 and the outer surface of the static conductive wire 14 are both provided with an insulating coating. When static friction is generated, the sliding groove 9 will be in contact with the first time, and the crushing pestle 3 will be in contact with the ground.

The static conductive wire 14 and the crushing pestle 3 are fixedly connected, and the insulating coating is used again to further reduce the possibility of static electricity directly grounding. The vertical distance between the upper end of the connecting column 11 and the upper end of the crushing pestle 3 is smaller than the vertical distance between the lower end of the connecting column 11 and the bottom end of the sliding groove 9, so that the connecting column 1 When the connecting column 11 is fully retracted to the inner cavity of the sliding groove 9, the lower end of the connecting column 11 still does not contact the inner bottom end of the sliding groove 9, so that the connecting column 11 and the crushing pestle 3 slide while the striking piston 2 can fully strike the upper end of the crushing pestle 3. A pair of handles 101 are fixedly connected to the upper end of the crusher shell 1, and the outer circumferential surfaces of the pair of handles 101 are fixedly connected to the buffer silicone layer.

The outer circumferential surface of the connecting block 34 contacts the inner wall of the cavity 31 so that the connecting block 34 can be pressed down by stably pushing the buffer cylinder 37, thereby improving the stability of the buffer cylinder 37 pressing down, and cooperating with the wear-resistant layer to reduce the wear of the connecting block 34 and the inner wall of the cavity 31, thereby improving the service life. The inner wall of the adsorption groove 20 is fixedly connected with a protective net 2001, and the protective net 2001 is made of stainless steel. The possibility of gravel entering the protective tube 8 through the adsorption groove 20 is reduced through the protective net 2001. The inner wall of the conductive ring 17 is fixedly connected with a rubber insulating layer 1701. The rubber insulating layer 1701 is in contact with the wool fiber 15. In the process of crushing, the wool fiber 15 will shake with the electrostatic conductive wire 14 as the crusher shell 1 is adjusted. The conductive ring 17 is likely to be in contact with the wool fiber 15. The rubber insulating layer 1701 isolates the static electricity from the ground and improves the electrostatic adsorption effect on dust.

[0044] See also Figure 4 The upper end of the connecting column 11 is fixedly connected with a rubber protective layer 1101. The striking piston 2 only causes sliding friction between the connecting column 11 and the crushing pestle 3 during the striking process. Finally, the lower end of the striking piston 2 will fully strike the crushing pestle 3. The rubber protective layer 1101 not only does not affect the striking effect of the striking piston 2 on the crushing pestle 3, but also reduces the rigid collision between the connecting column 11 and the striking piston 2, thereby increasing the service life of the connecting column 11.

[0045] Working principle: The crusher shell 1 is pressed against the road surface through the protective cylinder 8. The upper end of the crusher shell 1 is held by the hand support column to keep the crusher shell 1 stable. Due to the weight of the crusher shell 1, the protective cylinder 8 is retracted upward through the first spring 7 and the fixing rod 6 until the lower end of the crushing pestle 3 contacts the road surface. The striking piston 2 is started to strike the crushing pestle 3 downward. In the process of striking and crushing the road surface, the reaction force of the road surface on the crusher shell 1 is buffered by the protective cylinder 8 and the first spring 7 to reduce the vibration amplitude of the crusher shell 1. As the crushing operation continues, the striking piston 2 is used to strike the crushing pestle 3. During the striking process, the connecting column 11 is first made to slide relative to the crushing pestle 3. The heat generated during the sliding friction is conducted to the carbon dioxide elastic airbag 33 through the heat conducting rod 32, so that the carbon dioxide elastic airbag 33 expands. The expanded carbon dioxide elastic airbag 33 cooperates with the connecting block 34 and the connecting block 35 to push the buffer cylinder 37 downward, so that the lower end of the buffer cylinder 37 contacts the road surface, and cooperates with the protective cylinder 8 for double buffering, further reducing the vibration amplitude of the crusher shell 1, thereby reducing the possibility of hand fatigue of the staff due to vibration, and improving work efficiency. During the sliding process between the crushing pestle 3, the mutual friction between the hard rubber layer 12 and the fur layer 13 generates static electricity on the surface of the fur layer 13, and the static electricity is conducted to the wool fiber 15 through the static electricity conducting wire 14. The heat generated during the friction between the hard rubber layer 12 and the fur layer 13 is conducted and reused in conjunction with the heat conducting rod 32, thereby reducing the vibration amplitude of the crusher shell 1 and increasing the service life of the fur layer 13. During the impact and crushing process, the crushed stones generated are directly isolated and protected by the protective tube 8, thereby reducing the possibility of the crushed stones splashing everywhere, and then the wool fiber 15 with static electricity is used to The generated dust is adsorbed to reduce the possibility of dust being raised and the safety hazard caused to the staff. When the crusher shell 1 is lifted by hand, the static electricity eliminating metal block 16 is lifted upward along with the crusher shell 1, and the lower end of the crushing pestle 3 is first separated from the ground, and the lower end of the protective tube 8 is still in contact with the ground. When the lower end of the protective tube 8 reaches the critical point of separation from the ground, the static electricity eliminating metal block 16 is in contact with the conductive ring 17, and the static electricity is conducted to the ground through the conductive ring 17 in cooperation with the crushing pestle 3, so that the static electricity can be eliminated immediately when no adsorption operation is performed, thereby reducing the possibility of static electricity causing safety hazards to personnel.
