[0027] In view of the problems existing in the prior art, an embodiment of the present invention provides a dust control device for cutting equipment, such as Figure 1As shown, the dust control device for cutting equipment includes an air inlet duct assembly 1, and a cutting equipment body 50 arranged in the air inlet duct assembly 1, one end of the air inlet duct assembly 1 (which can be understood as the right end) is connected to a first rectangular tube 2, the free end of the first rectangular tube 2 (which can be understood as the right end) is connected to a first hose 4, the free end of the first hose 4 (which can be understood as the right end) is connected to a dust reduction box 6, and the first hose 4 can adjust the distance between the air inlet duct assembly 1 and the dust reduction box 6; dust reduction liquid is provided at the bottom of the dust reduction box 6, and a second rectangular tube 7 is connected to the dust reduction box 6 (which can be understood as the right side plate), and the free end of the second rectangular tube 7 (which can be understood as the right end) is interconnected with the fan 9, and also includes an atomizing spray mechanism 10, the atomizing spray mechanism 10 extracts the dust reduction liquid (which can be understood as water) and sprays it into the dust reduction box 6 in an atomized state.

[0028] The dust control device for cutting equipment can solve the problem of flying dust at the work site, can collect dust for centralized treatment, thereby protecting the health of workers and the environment. By using the dust control device for cutting equipment at the construction site, dust occupational diseases can be effectively controlled.

[0029] The dust control device for cutting equipment adopts the idea of ​​"absorption", "reduction" and "filtration". A high-speed fan 9 is set in the cavity of the device to generate negative pressure to suck the high-speed dust flow generated when cutting stones and tiles into the cavity of the device. An atomizing spray mechanism 10 is set in the cavity of the device to reduce the dust in the airflow. Finally, a small amount of dust is absorbed by the air filter cotton 8, and the air after the dust airflow is filtered is discharged by the fan 9. In one example, a water filter cotton (not shown) is arranged above the dust reduction liquid. The water filter cotton is arranged in the dust reduction box 6, specifically below the second rectangular tube 7, to prevent the gas from passing through the second rectangular tube 7 to enter the fan 9. The structural design of the present invention is reasonable and can meet the requirements of dust collection and water circulation. The water filter cotton and the air filter cotton 8 can be reused.

[0030] In one embodiment, Figure 1 As shown, the air inlet duct assembly 1 is provided with a sensor 3. When the sensor 3 senses that the cutting device body 50 is close to the air inlet duct assembly 1 or enters the air inlet duct assembly 1, the fan 9 and the atomizing spray mechanism 10 are intelligently started to work. In one example, when the sensor 3 senses that the cutting device body 50 is close to the air inlet duct assembly 1 or there is dust in the air inlet duct assembly 1, the fan 9 and the atomizing spray mechanism 10 are also intelligently started to work. The setting of the sensor 3 can effectively improve the intelligence of the equipment, which can reduce the difficulty of operating the equipment and improve the efficiency of extracting dust.

[0031] During operation, when the sensor 3 controls the fan 9 to start, the fan 9 will draw out the dust at the air inlet duct assembly 1 through the first rectangular tube 2, the first hose 4, the dust reduction box 6 and the second rectangular tube 7, preventing the dust from escaping into the air at the air inlet duct assembly 1.

[0032] In one embodiment, Figure 1 As shown, the dust control device for cutting equipment also includes M guide plates 5, which are all arranged in the first hose 4, and the M guide plates 5 are arranged on the same horizontal line, M is a positive integer greater than or equal to 2, and the number of guide plates 5 can be set to two, three or more, preferably, the M guide plates 5 are arranged at equal distances in the first hose 4. The dust control device for cutting equipment also includes N air filter cottons 8, which are all arranged in the second rectangular tube 7, and the N air filter cottons 8 are arranged on the same horizontal line, N is a positive integer greater than or equal to 2, and the number of air filter cottons 8 can be set to two, three or more, preferably, the N air filter cottons 8 are arranged at equal distances in the second rectangular tube 7.

[0033] In one embodiment, Figure 1 As shown, the atomizing spray mechanism 10 includes an atomizing spray machine 101, and the atomizing spray machine 101 is interconnected with the fan 9. The liquid inlet of the atomizing spray machine 101 is connected to a first guide pipe 102, and the free end of the first guide pipe 102 (which can be understood as the left end) is connected to the dust reduction box 6. The first guide pipe 102 is arranged close to the bottom of the dust reduction box 6, and the first guide pipe 102 is connected to water. The liquid outlet of the atomizing sprayer 101 is connected to a second guide pipe 103, and the free end (which can be understood as the left end) of the second guide pipe 103 is connected to the dust reduction box 6. A storage box 104 is provided on the inner wall of the dust reduction box 6. The storage box 104 is connected to the second guide pipe 103, and a plurality of atomizing nozzles 105 are connected to the storage box 104. The free ends of the plurality of atomizing nozzles 105 are fixedly connected to the inner wall of the dust reduction box 6, and the atomizing nozzles 105 are in a mesh structure.

[0034] When working, the atomizing sprayer 101 is started, and water in the dust reduction box 6 will be drawn through the first guide pipe 102 and the water will be atomized. The atomized water will be sprayed into the dust reduction box 6 through the combined structure of the second guide pipe 103, the storage box 104 and the atomizing nozzle 105, thereby reducing the dust in the air in the dust reduction box 6.

[0035] In order to make all the gas sucked into the dust suppression box 6 pass through the atomizing nozzle 105, thereby improving the dust removal efficiency, in one embodiment, as shown in FIG. Figure 1As shown, the atomizing spray mechanism 10 also includes a third guide pipe 106, which is used to guide the gas in the first hose 4 to move above several atomizing nozzles 105, so that the gas must pass through several atomizing nozzles 105 during the process of moving from top to bottom, thereby improving the dust removal efficiency. The third guide pipe 106 is fixedly installed on the dust reduction box 6. The third guide pipe 106 is used for connecting the first hose 4 with the dust reduction box 6, and the third guide pipe 106 guides the dust-containing gas to move above the plurality of atomizing nozzles 105 so that the dust-containing gas passes downward through the plurality of atomizing nozzles 105. The third guide pipe 106 includes a horizontal section 1061 fixedly plugged into the dust reduction box 6, the free end of the horizontal section 1061 is connected to a first vertical section 1062, the free end of the first vertical section 1062 is connected to an arc section 1063, the free end of the arc section 1063 is connected to a second vertical section 1064, and the first vertical section 1062 is fixedly plugged into the plurality of atomizing nozzles 105. It is worth noting that the opening of the second vertical section 1064 is downward, so that water will not enter the second vertical section 1064, thereby preventing the dust removed from the air from being deposited in the third guide tube 106, thereby preventing the third guide tube 106 from being blocked.

[0036] In one embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the air inlet duct assembly 1 includes a bottom plate 11 and a top plate 17, and the top plate 17 is connected to the first rectangular tube 2 through a metal hinge 18. Two groups of first vertical plates 12 and third vertical plates 15 are arranged between the bottom plate 11 and the top plate 17. The third vertical plate 15 is arranged above the first vertical plate 12, and the first vertical plate 12 is fixedly arranged on the lower end surface of the top plate 17. The first vertical plate 12 is arranged on the upper end surface of the bottom plate 11, and a second vertical plate 13 is arranged at the upper end of the first vertical plate 12. A vertical groove 14 is opened on the third vertical plate 15, and the second vertical plate 13 is movably inserted in the vertical groove 14. The bottom plate 11, the top plate 17 and the two groups of first vertical plates 12 and the third vertical plate 15 form a working chamber. The arrangement of this embodiment enables the top plate 17 and the third vertical plate 15 to rotate upward or downward relative to the bottom plate 11, so that the size of the working chamber can be adjusted according to different working environments; and the arrangement of the combined structure of the second vertical plate 13 and the vertical groove 14 can achieve side blocking to prevent dust from escaping from the side to the outside of the air inlet duct assembly 1.

[0037] In one embodiment, Figure 4As shown, the air inlet duct assembly 1 also includes a first guide support assembly 16. The first guide support assembly 16 is used for connecting the second vertical plate 13 and the vertical slot 14 on the one hand, and for playing a role of limiting guidance on the other hand. The first guide support assembly 16 includes a first guide support rod 161, a first guide support cylinder 162, and a first guide support spring 163. The first guide support rod 161 is movably inserted in the first guide support cylinder 162, the first guide support spring 163 is wound and arranged outside the first guide support rod 161, and the two ends of the first guide support spring 163 are respectively fixedly connected to the side wall of the first guide support rod 161 and the outer side wall of the first guide support cylinder 162. The first guide support rod 161 is connected to the top wall of the vertical slot 14 (specifically hinged), and the first guide support cylinder 162 is connected to the second vertical plate 13 (specifically hinged).

[0038] When the cutting device body 50 is working, a large amount of sparks and dust (including solid particles) will be cut out. If the sparks and dust are directly hit against the sensor 3, the sensor 3 may be easily damaged. In order to solve the above problem, in one embodiment, Figure 6 and Figure 7 As shown, the dust control device for cutting equipment also includes an isolation mechanism 20, which is used for intermittently blocking the sensor 3. Specifically, when the cutting equipment body 50 is not working, the sensor 3 is not blocked, and when the cutting equipment body 50 is working, the sensor 3 is blocked. The isolation mechanism 20 includes a first mounting groove 201 provided on the lower end surface of the top plate 17, the sensor 3 is fixed on the top wall of the first mounting groove 201, and an isolation groove 202 provided on the top plate 17 and interconnected with the first mounting groove 201, an isolation plate 203 is movably inserted in the isolation groove 202, a heat conducting plate 204 is inlaid on the isolation plate 203, a push-pull rod 205 is fixedly connected to the upper end surface of the isolation plate 203, the push-pull rod 205 is movably inserted in a movable through hole 206, the movable through hole 206 is provided on the top plate 17, a cylinder arm 207 is fixedly connected to the side wall of the push-pull rod 205, the free end of the cylinder arm 207 is fixedly connected to the driving end of a driving cylinder 208, and the driving cylinder 208 is fixedly arranged on the upper end surface of the top plate 17.

[0039] When working, the sensor 3 controls the fan 9 and the atomizing sprayer 101 to start, and also controls the driving cylinder 208 to start. The driving cylinder 208 moves downward with the isolation plate 203 through the cylinder arm 207 and the push-pull rod 205, completing the blocking of the first mounting groove 201, thereby protecting the sensor 3. In order for the sensor 3 to work better, a heat conducting plate 204 is provided on the isolation plate 203 in the present invention. Through the heat conduction of the heat conducting plate 204, the sensor 3 can control the device in real time. Specifically, the sensor 3 controls the device by sensing the temperature change. When the cutting device body 50 is working, the splashing solid particles will cause the temperature on the heat conducting plate 204 to rise when the impact force hits the heat conducting plate 204, generating splashing sparks, which will also cause the temperature on the heat conducting plate 204 to rise. In this way, the sensor 3 can monitor and control the entire device by sensing the temperature change on the heat conducting plate 204.

[0040] In order to prevent dust from escaping from the connection between the top plate 17 and the first rectangular tube 2, in one embodiment, as Figure 8 As shown, the dust control device for cutting equipment also includes a sealing mechanism 30, and the sealing mechanism 30 is used for sealing the connection between the top plate 17 and the first rectangular tube 2.

[0041] In one example, the sealing mechanism 30 further includes a second guide support assembly 303, and the second guide support assembly 303 is used to connect the arc-shaped sealing plate 301 and the sealing groove 302. The second guide support assembly 303 includes a second guide support rod 3031, a second guide support cylinder 3032 and a second guide support cylinder 3033, the second guide support rod 3031 is movably inserted in the second guide support cylinder 3032, the second guide support cylinder 3033 is wound and arranged outside the second guide support rod 3031, and the two ends of the second guide support cylinder 3033 are respectively fixedly connected to the side wall of the second guide support rod 3031 and the outer side wall of the second guide support cylinder 3032, the second guide support rod 3031 is connected to the top wall of the sealing groove 302, and the second guide support cylinder 3032 is connected to the upper end surface of the arc-shaped sealing plate 301.

[0042] When the cutting device body 50 is working, in order to avoid damage to the sensor 3 due to excessive temperature, in one embodiment, Fig. 9As shown, the dust control device for cutting equipment also includes a cooling mechanism 40, and the cooling mechanism 40 includes a first air duct 401 embedded in the top plate 17, one end of the first air duct 401 (which can be understood as the upper end) is connected to a blower (not shown), and the other end of the first air duct 401 (which can be understood as the lower end) is connected to a second hose 402, and the second hose 402 is arranged in a second mounting groove 403, and the second mounting groove 403 is opened on the isolation plate 203, and the free end of the second hose 402 (which can be understood as the lower end) is connected to a second air duct 404, and the second air duct 404 is fixedly plugged on the isolation plate 203 and the heat conducting plate 204, and the free end of the second air duct 404 (which can be understood as the lower end) is connected to a cooling groove 405, and the cooling groove 405 is opened on the heat conducting plate 204, and the opening of the cooling groove 405 is arranged toward the sensor 3, and a connecting hole 406 is opened on the top plate 17.

[0043] During operation, when the sensor 3 senses that the temperature in the first installation groove 201 is equal to or exceeds the preset threshold, the blower will be controlled to start, and cooling gas will be introduced into the first installation groove 201 through the first air duct 401, the second hose 402, the second air duct 404 and the cooling groove 405, thereby reducing the air temperature in the first installation groove 201, thereby protecting the sensor 3.

[0044] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments.
