DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0043] The present invention will be further described below in conjunction with the embodiments.

[0044] Example:

[0045] A mobile dust removal equipment for coal mines, such as Figure 1-9 As shown, it includes two control boxes 100, which are slidably connected to the tracks on both sides of the mine tunnel respectively. A dust collector, a water collecting tank and a circulating pipe system are respectively arranged inside the control box 100. It is worth noting that the circulating pipe system is used by the control box 100 to discharge the dust collected by the dust collector and collect water from the outside to enter the water collecting tank. The dust collector, the water collecting tank and the circulating pipe system are all well-known existing technologies and are not described in detail here. A connecting pipe 101 is rotatably connected to the bottom of the control box 100, and a rubber hose 103 is fixedly connected to the bottom pipe mouth of the connecting pipe 101. A fixed pipe 105 is fixedly connected to one end of the rubber hose 103, and a supporting disc 120 is fixedly connected to one end of the fixed pipe 105. It should be noted that the connecting pipe 101 and the fixed pipe 105 are connected by a rubber hose 103, and the rubber hose 103 has a telescopic function. In actual use, the intermittent stepping and pressing package The protective shell surrounding the dust collection pipe 300 will not affect the cleaning and dust removal function of the equipment. It can be understood that when a person or a vehicle steps on the protective shell surrounding the dust collection pipe 300, the equipment does not stop, the rubber hose 103 extends, and the dust collection pipe 300 stays at the stepped position for a short period of time. After the person or vehicle leaves, the stepping ends, and the rubber hose 103 restores with the dust collection pipe 300, that is, when a small number of people or vehicles pass through the lane quickly, the equipment can work normally; the bottom end of the connecting pipe 101 is fixedly connected with a connecting shaft 102, and the connecting shaft 102 is connected to an external rotary drive device. It should be further explained that the connecting shaft 102 can rotate with the connecting pipe 101 and the dust collection pipe 300. It can be understood that when a large number of people or vehicles enter the lane, the dust collection pipe 300 can be retracted to both sides of the lane, which does not affect the passage of people and vehicles and does not cause damage to the equipment;

[0046] The arc-shaped water pipe 200 is arranged between the two control boxes 100 and communicated with them. A water pump 201 is arranged on the top of the arc-shaped water pipe 200, and uniformly distributed atomizers are arranged on the lower end of the arc-shaped water pipe 200. It is worth noting that the shape of the arc-shaped water pipe 200 is adjusted according to the shape of the lane, so that the arc-shaped water pipe 200 moves along the top of the lane, and the atomizer thereon sprays water mist into the inside of the lane, and the dust combines with the water mist and finally falls to the ground, which is convenient for cleaning;

[0047] A plurality of dust suction pipes 300, wherein one group of dust suction pipes 300 is fixedly connected to one end of the support disc 120, each group of dust suction pipes 300 comprises a first dust suction pipe 310, a second dust suction pipe 320 and a third dust suction pipe 330, the first dust suction pipe 310, the second dust suction pipe 320 and the third dust suction pipe 330 are of equal length and have dust suction holes processed at the bottom ends, the inner diameter of the first dust suction pipe 310 is equal to the outer diameter of the second dust suction pipe 320, the inner diameter of the second dust suction pipe 320 is equal to the outer diameter of the third dust suction pipe 330, the inner wall of the first dust suction pipe 310 is slidably connected to the outer wall of the second dust suction pipe 320, and the second dust suction pipe 320 is slidably connected to the outer wall of the second dust suction pipe 320. 0 is slidably connected to the outer wall of the third dust suction pipe 330, the two groups of dust suction pipes 300 are connected by a sealing ring 340, and one end of the two groups of dust suction pipes 300 is connected to two first dust suction pipes 310 or two second dust suction pipes 320, and the tail end of the last group of dust suction pipes 300 is fixedly connected to a closing plate 350. It is worth noting that the first dust suction pipe 310, the second dust suction pipe 320, and the third dust suction pipe 330 form a group of dust suction pipes 300. When the dust suction pipes 300 need to be retracted, the length of each group of dust suction pipes 300 is the length of one first dust suction pipe 310. In this solution, if Fig.10 As shown, one end of a support disc 120 is connected to four groups of dust collection pipes 300, and the length thereof is L. After the support disc 120 is retracted, the length thereof is one third of L. Compared with the prior art, in which the telescopic length is one half of the whole, the telescopic length of the present solution is two thirds of the whole. In actual use, the retracted dust collection pipes 300 can allow small and medium-sized crawler-type equipment to pass through the lane;

[0048] It should also be noted that a protective shell is provided on the outer side of the upper end of the bottom pipe of the fluid dust removal device in this solution, and the protective shell can protect the pipe at the bottom of the device from external pressure directly acting on the pipe, thereby protecting the pipe;

[0049] The 312th wheel 306 is provided with the first support rod 314, the second support rod 315 is provided with the first support rod 316, the second support rod 317 is provided with the first support rod 318, the 312th wheel 306 is provided with the first support rod 319, the 312th wheel 306 is provided with the second support rod 317, the 312th wheel 306 is provided with the second support rod 319, the 312th wheel 306 is provided with the second support rod 318 The cam 332 is provided with a third support rod 334 at one end thereof, and the third support rod 334 is provided with a third support rod 336 at the other end thereof.

[0050] The inner wall of the fixed tube 105 is fixedly connected to the limited position connecting rod 106 through a cross, and the inner wall of one end of the limited position connecting rod 106 is rotatably connected to the rotating shaft 107. The inner wall of the bottom pipe opening of the connecting pipe 101 is fixedly connected to the limited position connecting plate 108 through a cross. A sliding groove is processed on one side of the limited connecting plate 108, and the rotating shaft 107 is slidably connected to the inner wall of the sliding groove of the limited connecting plate 108. It is worth noting that the mechanism composed of the limited connecting rod 106, the rotating shaft 107, and the limited connecting plate 108 can ensure that the fixed tube 105 can only move left and right with the dust collection pipe 300, but will not move up and down, thereby making the distance between the dust collection pipe 300 and the ground of the lane remain unchanged, and the cleaning effect of the dust remains unchanged; the outer wall of the bottom pipe opening of the connecting pipe 101 is fixedly connected to the electric push ring 110 through a connecting plate, and one end of the connecting plate at the bottom pipe opening of the connecting pipe 101 The one-way return lever 104 is fixedly connected and distributed in a circumference. It should be noted that the one-way return lever 104 can only rotate in one direction and has a reset function. Therefore, when an outsider steps on the dust suction pipe 300 and causes the dust suction pipe 300 to stop at that position, the rubber hose 103 extends and squeezes the one-way return lever 104. When the outsider leaves, the stepping pressure disappears. The reset function of the one-way return lever 104 can quickly reset the rubber hose 103 and the fixed pipe 105. When the dust suction pipe 300 needs to be rotated, the output end of the electric push ring 110 extends to surround the rotation axis of the one-way return lever 104 and limit it to ensure that the rubber hose 103 and the fixed pipe 105 will not rotate relative to the electric push ring 110 during the rotation of the whole, so that the whole keeps consistent movement.

[0051] Furthermore, it also includes a telescopic mechanism for providing a driving force for the extension and shortening of each group of dust collection pipes 300, and the telescopic mechanism includes a driving turntable 122 connected to one end of the support disc 120 through a rotating shaft, and one end of the support disc 120 is movably connected to a ring 123 from to through a connecting rod, and the outer walls of the driving turntable 122 and the ring 123 from to are processed with tooth grooves, and the tooth grooves of the driving turntable 122 and the ring 123 from to are meshed with each other; an electric track 121 is fixedly connected to one end of the support disc 120, and the electric slider on the electric track 121 is fixedly connected to The supporting connecting rod 124 has a ball at one end thereof; it also includes an intermediate round rod 130, a limiting groove 132 is processed on the inner wall of the front end of the intermediate round rod 130, and the ball on the supporting connecting rod 124 is slidably connected to the inner wall of the limiting groove 132, and the outer wall of the front end of the intermediate round rod 130 is processed with evenly distributed triangular teeth 131, and the triangular teeth 131 on the intermediate round rod 130 are meshed with the tooth grooves from to the ring 123, and the inner wall of the intermediate round rod 130 is processed with a threaded groove. It is worth noting that the electric slider of the electric track 121 is limited by the ball on the supporting connecting rod 124. The middle round rod 130 is controlled to move forward and backward by sliding in the position groove 132; the mobile connecting rod 140 is fixedly connected to the wing plate of the closing plate 350, and the mobile connecting rod 140 is fixedly connected with threaded strips around it. The threaded strips of the mobile connecting rod 140 and the threaded grooves of the middle round rod 130 are meshed with each other for transmission. The inner diameter of the mobile connecting rod 140 is larger than the length and width of the electric slider on the electric track 121. It should be noted that when each set of dust collection pipes 300 is retracted, the electric slider on the electric track 121 first retracts with the middle round rod 130 until the electric slider slides to the guide rail At the other end, at this time, the tooth grooves on the ring 123 from to and the triangular teeth 131 on the intermediate round rod 130 are located in the same plane. At this time, the drive turntable 122 is rotated, and the tooth grooves on it are meshed with the tooth grooves on the ring 123 from to to make the ring 123 from to rotate, and similarly, the intermediate round rod 130 is rotated. When the thread groove inside the intermediate round rod 130 is meshed with the thread strip on the moving connecting rod 140, the moving connecting rod 140 is contracted, and finally the moving connecting rod 140 and the intermediate round rod 130 are both located at the position of the electric track 121; in this solution, as Fig.10 As shown, the length of the electric track 121 is S, the length of the middle round rod 130 is W, and the length of the moving link 140 is P. The lengths of S, W, and P are equal and are all equal to one third of L;

The dust suction holes on the dust suction pipe 300 at the bottom of the equipment are connected to the dust collector, so that it can clean and recycle the dust on the ground of the lane; when a small number of people and vehicles pass through the lane, the dust removal work of this equipment will not stop, and under the action of the rubber hose 103 and the one-way return lever 104, the protective shell of the dust suction pipe 300 will stop for a while, and then reset to continue working; when a large number of people, equipment or crawler-type equipment enters the lane, the extension and rotation of the dust suction pipe 300 are controlled by the remote terminal to avoid it;

[0053] When retracting, the output end of the electric push ring 110 extends out to trap the one-way return rod 104, and the electric slider on the electric track 121 first retracts with the intermediate round rod 130 until the electric slider slides to the other end of the guide rail. At this time, the tooth grooves on the from to ring 123 and the triangular teeth 131 on the intermediate round rod 130 are located in the same plane. At this time, the drive turntable 122 rotates, and the tooth grooves on it mesh with the tooth grooves on the from to ring 123 to transmit the from to ring 123 to rotate, and similarly, the intermediate round rod 130 rotates, and the thread grooves inside the intermediate round rod 130 mesh with the thread strips on the moving connecting rod 140 Downward, the moving connecting rod 140 is retracted, and finally the moving connecting rod 140 and the middle round rod 130 are both located at the position of the electric track 121, and the second dust suction pipe 320 and the third dust suction pipe 330 in each group of dust suction pipes 300 are slid into the inside of the first dust suction pipe 310, so that the length of the dust suction mechanism is one third L at this time, which is convenient for small and medium-sized crawler equipment and vehicles to enter the site. The external rotary drive device drives the connecting shaft 102 to rotate the dust suction pipe 300 by 90 degrees, so that the dust suction pipe 300 is retracted on both sides of the lane, and a large number of people or vehicles can enter the lane at this time;

[0054] When extending, the external rotary drive device drives the connecting shaft 102 to rotate with the dust collection pipe 300 to the middle of the alley, drives the turntable 122 to rotate, and the tooth grooves on the turntable 122 mesh with the tooth grooves on the from to ring 123 to transmit the from to ring 123 to rotate, and similarly, the middle round rod 130 rotates, and when the thread groove inside the middle round rod 130 meshes with the thread strip on the movable connecting rod 140, the movable connecting rod 140 is extended, and the electric slider on the electric track 121 first extends the middle round rod 130, so that the first dust collection pipe 310, the second dust collection pipe 320, and the third dust collection pipe 330 in each group of dust collection pipes 300 are all unfolded to form dust collection pipes to remove dust from the alley floor.
