Description

Technical Field

[0001] The invention relates to the technical field of crushing, in particular to dust-reducing sand and gravel material crushing equipment for construction engineering. Background Art

[0002] Construction refers to the production activities during the implementation phase of engineering construction. It is the process of constructing various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. During the construction process, a lot of building materials are used and need to be transported. Sand and gravel crushers have a wide range of uses and have no requirements for the working environment. They can work indoors or outdoors, or in special circumstances (such as rainy and snowy days). Crushers are widely used in the fine and coarse crushing of metal and non-metallic ores, cement, refractory materials, abrasives, glass raw materials, construction, artificial sand making, and various metallurgical slags.

[0003] A large amount of dust will be generated when sand and gravel are broken. The existing sand and gravel breaking devices on the market do not have a good dust reduction effect. A large amount of dust will be generated during the breaking operation, which will pollute the environment and is very harmful to the health of the workers. It is not conducive to the use and operation of the equipment, and the crushing efficiency is reduced. Therefore, a new design was made to address this situation. Summary of the Invention

The motor controls the rotation of the crushing barrel to achieve the effect of crushing sand and gravel, optimize the size of sand and gravel particles, and facilitate subsequent transportation and different work needs. The lower side of the outer side of the crushing shell is fixedly connected to a buffer mechanism, and the distance between the crushing barrel and the crushing barrel is controlled by the pushing mechanism to facilitate the intake of particles of different sizes. Sand and gravel, thereby increasing the crushing capacity of the equipment, the bottom of the crushing shell is fixedly connected to a conical shell, and sand and gravel are easily splashed during the rotating crushing process of the crushing cylinder. The crushing cylinder is wrapped by the pushing mechanism, which reduces the space for sand and gravel splashing, and promotes multiple collisions of the splashed sand and gravel, thereby further improving the crushing effect of the equipment, improving the crushing quality and crushing efficiency of sand and gravel, and the bottom of the conical shell is fixedly connected to a discharge valve, which guides the flow of sand and gravel through the conical shell to reduce sand and gravel retention. Sand and gravel are discharged from the discharge valve for subsequent storage or processing, and the bottom of the crushing cylinder is fixedly connected to a rotating plate mechanism, and the outside of the rotating plate mechanism is fixedly connected to a collision mechanism on one side close to the discharge valve.

[0006] Preferably, the buffer mechanism includes a support frame body, and a first spring is sleeved on the outer side of the support frame body. When the crushing drum rotates to crush sand and gravel, sand and gravel inside the equipment collide, causing the equipment to shake. The first spring plays a shock-absorbing and buffering role, slowing down the vibration amplitude of the equipment and improving the stability of the equipment operation. The bottom of the support frame body is fixedly connected to a tripod, and the outer side of the tripod is fixedly connected to an outward expansion claw. The outward expansion claw increases the contact area between the tripod and the ground, thereby increasing the friction with the ground and further improving the stability of the equipment.

[0007] Preferably, the collision mechanism includes a connecting block, the outer side of which is fixedly connected to a tool, and the crushed stone processed by the crushing cylinder falls toward the conical shell, and contacts the crushed stone through the rotating tool, thereby performing secondary crushing on the sand and stone, further improving the crushing effect of the sand and stone, and crushing the unprocessed sand and stone or the sand and stone with larger particles above, avoiding uneven crushing of the sand and stone, and improving the operation quality of the equipment, the outer side of the tool is fixedly connected to a rotating rod, the outer side of the rotating rod is fixedly connected to a connecting plate, and the outer side of the connecting plate is fixedly connected to a billiard ball, and during the centrifugal rotation of the tool, the connecting plate drives the billiard ball to rotate, and the sand and stone are impacted and crushed by the impact generated by the rotation, and the contact area with the sand and stone is increased by rotating the billiard ball, thereby improving the secondary crushing efficiency.

[0008] Preferably, the rotating plate mechanism includes a connecting shaft, the outer side of the connecting shaft is fixedly connected to a rotating plate bracket, and the outer side of the rotating plate bracket is fixedly connected to a scraper on the side away from the connecting shaft. In the process of crushing sand and gravel, a large amount of sand and gravel dust is generated, which is easy to accumulate on the inner wall of the conical shell, so as to avoid excessive accumulation affecting the discharging effect. The connecting shaft drives the scraper to rub the inner wall of the conical shell through centrifugal rotation, thereby cleaning the problem of dust adhesion and prompting impurities to be discharged outward through the discharge valve, so as to keep the interior of the equipment unobstructed and avoid blockage caused by friction between impurities and sand and gravel inside the equipment. A silicone pad is fixedly connected to one side of the outside of the scraper. During the rotation of the scraper, it rubs against impurity particles, and the silicone pad has a certain protective effect on the components, increases the wear resistance of the components, reduces the wear of the components during operation, and thus extends the service life of the components. A square incision is opened on one side of the outer side of the silicone pad. By opening the square incision, the deformation performance of the components is increased by the groove, further improving the buffering effect of the components, and protecting the components. At the same time, the surface texture of the components is increased by the groove, further improving the peeling effect of attached impurities and improving the cleaning efficiency.

[0009] Preferably, the pushing mechanism includes a square frame, the outer side of the square frame is fixedly connected to an electric push rod, and the space between the arc baffle and the crushing cylinder is controlled by the electric push rod, so as to control the space for sand and gravel to splash, and avoid sand and gravel to fall directly after splashing, which causes the particles to remain large after crushing, affecting the crushing effect. Therefore, by narrowing the crushing space, one side of the outside of the electric push rod is fixedly connected to the arc baffle, and when sand and gravel splash, the arc baffle is collided and rebounded, thereby prompting the sand and gravel to collide multiple times, thereby improving the crushing effect of sand and gravel, and improving the crushing quality of sand and gravel, so as to meet the requirements of subsequent work on sand and gravel particle size.

[0010] Preferably, the protective mechanism includes an arc-shaped frame, a sliding rod is fixedly connected to the side of the outer side of the arc-shaped frame close to the arc-shaped baffle, and a second spring is sleeved on the outer side of the sliding rod. When sand and gravel splash onto the surface of the arc-shaped frame, the arc-shaped frame drives the sliding rod to squeeze the second spring, thereby achieving a shock-absorbing and buffering effect, reducing external kinetic energy, reducing damage to components, thereby extending the service life of the components, and avoiding serious damage to components caused by long-term splashing of sand and gravel, thereby affecting the operation effect of the equipment. The outer side of the sliding rod is slidably connected to the outer side of the arc-shaped baffle.

[0011] Preferably, a soft rubber block is fixedly connected to the side of the outer side of the arc-shaped frame away from the sliding rod. The soft rubber block has a protective effect on the components, increases the wear resistance of the components, reduces the damage to the components caused by sand and gravel, and thus extends the service life of the components.

[0012] Preferably, the dust reduction mechanism includes a dust reduction shell, the outer side of the dust reduction shell is fixedly connected to a fan. A large amount of smoke and dust is easily generated in the process of crushing sand and gravel, which causes great harm to the human respiratory system. The wind is generated by the fan to absorb the smoke and dust generated by the crushed sand and gravel. A hose can be set on the outside of the fan to collect and process the absorbed smoke and dust, prevent the smoke and dust from splashing, avoid pollution to the environment, reduce safety hazards of operators, and reduce safety hazards of equipment. The smoke and dust generated in the sand and gravel crushing process may contain combustible substances. When the smoke concentration reaches a certain level, it may cause an explosion when encountering open flames or high temperatures, causing serious casualties and property losses. The top of the inner wall of the dust reduction shell is fixedly connected to a rotating mechanism, and the bottom of the inner wall of the dust reduction shell is fixedly connected to a grille plate. The grille plate plays a role in blocking the entry of particles, avoiding the entry of broken and splashing particles, and preventing the ventilation effect from being affected.

[0013] Preferably, the rotating mechanism includes a receiving shaft, the outer side of the receiving shaft is rotatably connected to a cylindrical shell, and a paddle is fixedly connected to the middle of the outer side of the cylindrical shell. The paddle is driven to rotate by wind force, and the paddle controls the rotating bracket to drive the friction column to rotate, thereby rubbing the surface of the component, thereby achieving a cleaning effect on the inner wall of the equipment, peeling off the smoke and dust adsorbed on the inner wall, and scattering the adsorbed smoke and dust through suction for flow storage and processing, avoiding excessive adsorption of dust, which affects the ventilation effect of the equipment and avoids blockage, thereby maintaining the normal operation of the equipment, and the two ends of the outer side of the cylindrical shell are fixedly connected to the rotating bracket, and the friction column is fixedly connected between the opposite surfaces of the rotating bracket.

[0014] The present invention provides a dust-reducing sand and gravel material crushing device for construction engineering. It has the following beneficial effects:

[0015] 1. The dust-reducing sand and gravel material crushing equipment used in the construction of this construction project has a crushing mechanism design. Sand and gravel enter from the top of the crushing shell and are guided by the funnel plate to the middle of the crushing cylinder and the pushing mechanism. The motor controls the rotation of the crushing cylinder to achieve the effect of crushing sand and gravel, optimize the particle size of sand and gravel, and facilitate subsequent transportation and different work needs. The distance between the crushing cylinder and the pushing mechanism is controlled to facilitate the intake of sand and gravel of different sizes, thereby increasing the crushing capacity of the equipment. Sand and gravel are prone to splashing during the rotating crushing process of the crushing cylinder. The pushing mechanism wraps the crushing cylinder to reduce the space for sand and gravel splashing, and promotes multiple collisions of the splashed sand and gravel, thereby further improving the crushing effect of the equipment, improving the crushing quality and crushing efficiency of sand and gravel, guiding the flow of sand and gravel through the conical shell to reduce sand and gravel retention, and sand and gravel are discharged from the discharge valve for subsequent storage or processing.

[0016] 2. The dust-reducing sand and gravel material crushing equipment used in the construction project is designed with a collision mechanism. The crushed stones processed by the crushing cylinder fall into the conical shell and come into contact with the gravel through the rotating tool, thereby performing secondary crushing on the sand and gravel, further improving the crushing effect of the sand and gravel, and crushing the unprocessed sand and gravel or the sand and gravel with large particles above to avoid uneven crushing of sand and gravel and improve the operation quality of the equipment. Secondly, during the centrifugal rotation of the tool, the connecting plate drives the billiard ball to rotate, and the impact generated by the rotation impacts and crushes the sand and gravel, and the rotating billiard ball increases the contact area with the sand and gravel, thereby improving the secondary crushing efficiency.

[0017] 3. The dust-reducing sand and gravel material crushing equipment used in the construction project is designed with a rotating plate mechanism. During the sand and gravel crushing process, a large amount of sand and gravel dust is generated, which is easy to accumulate on the inner wall of the conical shell. To avoid excessive accumulation that affects the discharging effect, the connecting shaft drives the scraper to rub the inner wall of the conical shell through centrifugal rotation, so as to clean the problem of dust adhesion and promote the discharge of impurities through the discharge valve, so as to keep the interior of the equipment unobstructed and avoid blockage caused by friction between impurities and sand and gravel. Secondly, the scraper rubs with impurity particles during rotation, and the silicone pad has a certain protective effect on the components, increases the wear resistance of the components, reduces the wear of the components during operation, and thus extends the service life of the components. By opening square incisions and increasing the deformation performance of the components through grooving, the buffering effect of the components is further improved to protect the components. At the same time, the surface texture of the components is increased through grooving, which further improves the stripping effect of attached impurities and improves the cleaning efficiency.

[0018] 4. The dust-reducing sand and gravel material crushing equipment used in the construction project, through the pushing mechanism design, controls the space between the arc baffle and the crushing barrel through the electric push rod, so as to control the space for sand and gravel to splash, and avoid sand and gravel to fall directly after splashing, which causes the particles to remain large after crushing, affecting the crushing effect. Therefore, by reducing the crushing space, when the sand and gravel splash, it collides and rebounds against the arc baffle, thereby prompting the sand and gravel to collide multiple times, thereby improving the crushing effect of sand and gravel and improving the crushing quality of sand and gravel, so as to meet the requirements of subsequent work on the size of sand and gravel particles. Secondly, the distance between the arc baffle and the crushing barrel is controlled by the electric push rod, which is convenient for adjustment according to the size of sand and gravel, thereby adapting to the crushing effect of sand and gravel of different sizes.

[0019] 5. The dust-reducing sand and gravel material crushing equipment used in the construction project is designed with a dust reduction mechanism. The space between the arc baffle and the crushing barrel is controlled by an electric push rod, so as to control the space for sand and gravel to splash, and avoid sand and gravel to fall directly after splashing, which causes the particles to remain large after crushing and affects the crushing effect. Therefore, by reducing the crushing space, when the sand and gravel splash, they collide and rebound against the arc baffle, thereby prompting the sand and gravel to collide multiple times, thereby improving the crushing effect of sand and gravel and improving the crushing quality of sand and gravel, so as to meet the requirements of subsequent work on the size of sand and gravel particles. Secondly, the distance between the arc baffle and the crushing barrel is controlled by an electric push rod, which is convenient for adjustment according to the size of sand and gravel, thereby adapting to the crushing effect of sand and gravel of different sizes.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0030] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution: a dust-reducing sand and gravel material crushing equipment for construction engineering, comprising a crushing mechanism 1, a motor 4 is fixedly connected to the middle of the top of the crushing mechanism 1, a dust reduction mechanism 3 is fixedly connected to one side of the top of the crushing mechanism 1, and a pushing mechanism 2 is fixedly connected to the outer side of the crushing mechanism 1;

[0031] The crushing mechanism 1 includes a crushing shell 11, the top of the crushing shell 11 is fixedly connected to a receiving plate 13, the top of the receiving plate 13 is fixedly connected to the outside of the motor 4, the top of the inner wall of the crushing shell 11 is fixedly connected to a funnel plate 12, the output end of the motor 4 is fixedly connected to a crushing barrel 15, the lower side of the outside of the crushing shell 11 is fixedly connected to a buffer mechanism 14, the bottom of the crushing shell 11 is fixedly connected to a conical shell 16, the bottom of the conical shell 16 is fixedly connected to a discharge valve 17, the bottom of the crushing barrel 15 is fixedly connected to a rotating plate mechanism 19, and the side of the outside of the rotating plate mechanism 19 close to the discharge valve 17 is fixedly connected to a collision mechanism 18. Sand and gravel enter from the top of the crushing shell 11 and are guided by the funnel plate 12 so that the sand and gravel enter the middle of the crushing cylinder 15 and the pushing mechanism 2. The motor 4 controls the rotation of the crushing cylinder 15 to crush the sand and gravel, optimize the particle size of the sand and gravel, and facilitate subsequent transportation and different work needs. The distance between the crushing cylinder 15 and the pushing mechanism 2 is controlled to facilitate the intake of sand and gravel of different sizes, thereby increasing the crushing capacity of the equipment. During the rotation and crushing of the crushing cylinder 15, sand and gravel are easily splashed. The pushing mechanism 2 wraps the crushing cylinder 15 to reduce the space for sand and gravel splashing, and promotes multiple collisions of the splashed sand and gravel, thereby further improving the crushing effect of the equipment, improving the crushing quality and crushing efficiency of sand and gravel, and guiding the flow of sand and gravel through the conical shell 16 to reduce sand and gravel retention. Sand and gravel are discharged from the discharge valve 17 for subsequent storage or processing.

[0032] The buffer mechanism 14 includes a support frame 141, with a first spring 142 sleeved around the outside of the support frame 141. A foot frame 143 is fixedly connected to the bottom of the support frame 141, and an outward expansion claw 144 is fixedly connected to the outside of the foot frame 143. As the crushing drum 15 rotates to crush sand and gravel, sand and gravel collide within the equipment, causing the equipment to shake. The first spring 142 acts as a shock absorber, reducing the amplitude of the equipment's vibration and improving its operational stability. The outward expansion claw 144 increases the contact area between the foot frame 143 and the ground, increasing friction with the ground and further improving the stability of the equipment.

[0033] The collision mechanism 18 includes a connecting block 181, a cutter 182 fixedly connected to the outside of the connecting block 181, a rotating rod 183 fixedly connected to the outside of the cutter 182, a connecting plate 184 fixedly connected to the outside of the rotating rod 183, and a billiard ball 185 fixedly connected to the outside of the connecting plate 184. The gravel processed by the crushing barrel 15 falls into the conical shell 16, and the rotating cutter 182 contacts the gravel, thereby performing a secondary crushing on the sand and gravel, further improving the crushing effect of the sand and gravel, crushing the unprocessed sand and gravel or the sand and gravel with still large particles, avoiding uneven crushing of the sand and gravel, and improving the operation quality of the equipment. Secondly, during the centrifugal rotation of the cutter 182, the connecting plate 184 drives the billiard ball 185 to rotate, and the impact generated by the rotation impacts and crushes the sand and gravel. The rotating billiard ball 185 increases the contact area with the sand and gravel, thereby improving the efficiency of secondary crushing.

[0034] The rotating plate mechanism 19 includes a connecting shaft 191, a rotating plate bracket 192 is fixedly connected to the outer side of the connecting shaft 191, a scraper 193 is fixedly connected to the side of the rotating plate bracket 192 away from the connecting shaft 191, a silicone pad 194 is fixedly connected to the outer side of the scraper 193, and a square incision 195 is opened on the outer side of the silicone pad 194. In the process of crushing sand and gravel, a large amount of sand and gravel dust is generated, which is easy to accumulate on the inner wall of the conical shell 16. To avoid excessive accumulation that affects the discharging effect, the connecting shaft 191 is driven by centrifugal rotation to drive the scraper 193 to rub the inner wall of the conical shell 16, so as to clean the problem of dust adhesion and promote the impurities to be discharged outward through the discharge valve 17, so as to keep the interior of the equipment unobstructed and avoid the friction between impurities and sand and gravel causing blockage inside the equipment. Secondly, the scraper 193 rubs against the impurity particles during rotation, and the silicone pad 194 has a certain protective effect on the components, increases the wear resistance of the components, reduces the wear of the components during operation, and thus extends the service life of the components. By opening a square incision 195 and increasing the deformation performance of the components through grooving, the buffering effect of the components is further improved, and the components are protected. At the same time, the surface texture of the components is increased through grooving, which further improves the stripping effect of attached impurities and improves the cleaning efficiency.

[0035] The second embodiment, based on the first embodiment, see Figures 5 and 6As shown, the pushing mechanism 2 includes a square frame 21, the outer side of which is fixedly connected to an electric push rod 22, an outer side of the electric push rod 22 being fixedly connected to an arc-shaped baffle 23, and an outer side of the arc-shaped baffle 23 away from the electric push rod 22 being fixedly connected to a protective mechanism 24. The electric push rod 22 controls the space between the arc-shaped baffle 23 and the crushing drum 15, thereby controlling the space for sand and gravel to splash, preventing the sand and gravel from falling directly after splashing, which would result in the particles remaining large after crushing and affecting the crushing effect. Therefore, by reducing the crushing space, the sand and gravel will collide and rebound against the arc-shaped baffle 23 after splashing, thereby promoting multiple collisions of the sand and gravel, thereby improving the crushing effect of the sand and gravel and improving the crushing quality of the sand and gravel, thereby meeting the requirements of the sand and gravel particle size in subsequent work. Secondly, the electric push rod 22 controls the distance between the arc-shaped baffle 23 and the crushing drum 15, thereby facilitating adjustment according to the size of the sand and gravel, thereby adapting to the crushing effect of sand and gravel of different sizes.

[0036] The protective mechanism 24 includes an arc-shaped frame 241. A sliding rod 242 is fixedly connected to the side of the arc-shaped baffle 23 on the outside of the arc-shaped frame 241. A second spring 243 is sleeved on the outside of the sliding rod 242. The outside of the sliding rod 242 is slidably connected to the outside of the arc-shaped baffle 23. When sand and gravel splash onto the surface of the arc-shaped frame 241, the arc-shaped frame 241 drives the sliding rod 242 to squeeze the second spring 243, thereby achieving a shock-absorbing and buffering effect, reducing external kinetic energy and minimizing damage to components, thereby extending the service life of the components and preventing serious damage to components caused by prolonged sand and gravel splashing, which could affect the operation of the equipment.

[0037] A soft rubber block 244 is fixedly connected to the side of the curved frame 241 away from the sliding rod 242. A groove 245 is defined on one side of the outer surface of the block 244. The block 244 protects the components, increasing their wear resistance and reducing damage from sand and gravel, thereby extending their service life. The groove 245 also increases the deformation resistance of the components, further enhancing their cushioning effect and improving their ability to absorb the kinetic energy of sand and gravel splashes.

[0038] The third embodiment, based on the first and second embodiments, see Figures 7 and 8As shown, the dust reduction mechanism 3 includes a dust reduction shell 31, a fan 32 is fixedly connected to the outside of the dust reduction shell 31, a rotating mechanism 34 is fixedly connected to the top of the inner wall of the dust reduction shell 31, and a grille plate 33 is fixedly connected to the bottom of the inner wall of the dust reduction shell 31. A large amount of smoke and dust is easily generated in the process of crushing sand and gravel, which is extremely harmful to the human respiratory system. The wind is generated by the fan 32 to absorb the smoke and dust generated by the crushed sand and gravel. A hose can be installed on the outside of the fan 32 to collect and process the absorbed smoke and dust, prevent the smoke and dust from splashing, avoid pollution to the environment, reduce safety hazards of operators, and reduce safety hazards of equipment. The smoke and dust generated in the sand and gravel crushing process may contain combustible substances. When the smoke and dust concentration reaches a certain level, it may cause an explosion when encountering open flames or high temperatures, causing serious casualties and property losses. The grille plate 33 plays a role in blocking the entry of particles, preventing the entry of crushed and splashed particles, and preventing the ventilation effect from being affected.

[0039] Rotation mechanism 34 includes a connecting shaft 341, rotatably connected to a cylindrical housing 342 on its outer side. A paddle 343 is fixedly connected to the middle of the outer portion of cylindrical housing 342. Rotation brackets 344 are fixedly connected to both ends of the outer portion of cylindrical housing 342. Friction posts 345 are fixedly connected between opposing surfaces of rotation brackets 344. Wind power drives paddle 343 to rotate, which in turn controls rotation brackets 344, driving friction posts 345. This friction acts on the surface of the components, thereby cleaning the inner walls of the device and stripping away any dust adsorbed on the walls. This dust is then dispersed and stored by suction, preventing excessive dust adsorption that could affect the device's ventilation and prevent blockage, thereby maintaining normal operation.

[0040] During use, sand and gravel enter from the top of the crushing shell 11 and are guided by the funnel plate 12 so that the sand and gravel enter the space between the pushing mechanism 2 and the crushing cylinder 15. The crushing cylinder 15 is controlled to rotate by the motor 4. The rotation of the crushing cylinder 15 achieves the effect of crushing sand and gravel, thereby meeting the subsequent demand for sand and gravel particles. In the process of the crushing cylinder 15 crushing the sand and gravel, the impact causes the sand and gravel to splash to the outside of the pushing mechanism 2, and the rebound causes the sand and gravel to collide with the crushing cylinder 15 multiple times, thereby further improving the crushing effect and crushing quality of the sand and gravel. Due to gravity, the crushed sand and gravel fall to one side of the conical shell 16. At the same time, impurity particles also sink as the sand and gravel particles fall. In the process of the crushing cylinder 15 rotating, the collision mechanism 18 is driven to rotate to perform secondary collision and damage on the sand and gravel, thereby adjusting the size of the sand and gravel particles. Check for deficiencies and fill in the gaps to avoid omissions in the upper crushing process, which will affect the equipment's crushing effect on sand and gravel. Sand and gravel are discharged outward from the discharge valve 17. Impurity particles and dust are easily adsorbed on the inclined part of the conical shell 16 during the sinking process. When they accumulate too much, they are easy to cause friction with the sand and gravel particles, causing the two to be fixed inside the equipment. Therefore, the turntable mechanism 19 is rotated. On the one hand, impurities on the surface of the component are peeled off by friction, reducing impurity adhesion, reducing equipment pressure, and promoting impurity discharge. On the other hand, it avoids blockage caused by excessive accumulation of impurities, while reducing particle adhesion and keeping the material flow inside the equipment smooth. A dust reduction mechanism 3 is provided on the top of the crushing mechanism 1, which absorbs, stores and processes the smoke and dust through the dust reduction mechanism 3 to reduce the splashing of smoke and dust, reduce the impact of smoke and dust on operators, and protect the safety of operators.

[0041] Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative work should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
