Description

Technical Field

[0001] The invention relates to the field of dust removal of mining excavation equipment, in particular to energy-saving and environment-friendly dust removal mining excavation equipment. Background Art

[0002] A tunnel boring machine is a mechanical device specially used for tunnel excavation. It can carry out tunnel construction efficiently and safely. A tunnel boring machine integrates mechanical, electrical, hydraulic, optical and computer technologies. It includes shield machines for soft soil strata and hard rock tunnel boring machines (TBMs) for rock strata. The definition of a tunnel boring machine is relatively broad, and both shield machines and TBMs belong to the category of tunnel boring machines.

[0003] The tunnel boring machine uses the huge thrust generated by the hydraulic system to propel itself forward and achieve underground excavation. The cutter head of the tunnel boring machine is designed like a huge sharp blade. The cutter head is driven to rotate by an electric motor to cut and crush the rock, and then transport it to the conveyor belt through a screw conveyor, and the crushed rock is transported out through the conveyor belt.

[0004] At present, when the screw conveyor transports crushed stone to the conveyor belt, a large amount of dust will be generated when the cutter disc cuts the rock, and the crushed stone will collide with each other when being transported inside the screw conveyor, generating dust. When this dust is transported to the conveyor belt through the screw conveyor outlet, it will become a large amount of dust.

[0005] Dust generated during cutting and gravel transportation is mostly reduced by spraying water. When the tunnel boring machine works in the city, water can be directly supplied through the tap water pipe. However, when the tunnel boring equipment works in a remote mine, it is affected by the mine terrain and cannot be supplied with tap water like in the city. Therefore, water tanks are mostly used for water supply. By setting nozzles and water pumps on the water tanks, the water inside the water tanks is pumped out by the water pumps and sprayed out through the nozzles. Since the dust reduction position is close to the cutter disc (the gravel cut by the cutter disc is transported to the conveyor belt through a screw conveyor, and the end of the conveyor belt is normally only 3 to 4 meters away from the cutter disc), as the cutter disc continues to go deeper into the ground, the dust reduction position is farther and farther from the outside, making it increasingly difficult to add water to the water tank. Since the soil moisture and stone content are different in different terrains, when the soil is relatively wet and contains less stone, less dust is generated during the cutting process. When the soil is relatively dry and contains more stone, a large amount of dust will be generated during the cutting process. This dust needs to be handled in time, otherwise it will affect the health of the staff.

[0006] In the prior art, although the nozzle can adjust the water spray volume, the direction of the water spray is fixed, resulting in a small range of water spray. When less dust is generated during the cutting process, the dust can be reduced by directly adjusting the water spray volume of the nozzle. When the dust is heavy, increasing the water spray volume can achieve dust reduction, but it will be extremely wasteful of water resources, and in areas where it is difficult to add water, it greatly increases the workload of staff.

[0007] Therefore, an energy-saving and environment-friendly dust removal mining excavation equipment is proposed. Summary of the invention

[0008] In view of the fact that the nozzles in the above-mentioned or prior art can adjust the water spraying amount, but the direction of the water spraying is fixed, resulting in a small range of water spraying. When the dust is large, although increasing the water spraying amount can achieve dust reduction, it will greatly waste water resources and greatly increase the work intensity of the staff in areas where it is difficult to add water, the present invention is proposed.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1, reference Figures 1 to 3 , is the first embodiment of the present invention, which provides an energy-saving and environmentally friendly dust removal mining excavation equipment, which includes a cutting head 100, which includes a shell 101, one end of the shell 101 is connected to a cutter head 102, a screw conveyor 103 and a conveyor belt 104 are arranged inside the shell 101, the discharge port of the screw conveyor 103 corresponds to the position of the conveyor belt 104, a dust removal mechanism 200 is arranged inside the shell 101, the dust removal mechanism 200 is located at the discharge port of the screw conveyor 103, and the dust removal mechanism 200 includes a water tank 201 installed inside the shell 101, the water tank A through pipe 202 is connected to 201, one end of the through pipe 202 is connected to the inside of the water tank 201, and the other end of the through pipe 202 extends out of the water tank 201, a water pipe 203 is connected to the through pipe 202, and a nozzle 204 is connected to one end of the water pipe 203 away from the through pipe 202, and the nozzle 204 is installed on a support 205, and the support 205 is rotatably connected to the top of the water tank 201, and a bracket 206 is provided on the top of the water tank 201, and a driving component 207 is provided on the bracket 206, and a pumping component 208 is connected to the driving component 207, and an adjusting component 209 is provided on the support 205; Among them, the operation of the cutter disc 102, the screw conveyor 103 and the conveyor belt is a very mature existing technology; The nozzle 204 is preferably an atomizing nozzle 204 with adjustable water spraying amount, and the spraying amount of the nozzle 204 is selectively adjusted according to the size of the dust; By turning on the driving assembly 207, the operation of the driving assembly 207 can drive the pumping assembly 208 to pump out the water inside the water tank 201, and spray it out from the nozzle 204 through the water pipe 203, so as to deal with the dust and prevent the dust from causing harm to the workers; By setting the adjustment component 209, the pumping component 208 can drive the support 205 to rotate or not drive the support 205 to rotate when pumping water. When there are many rocks underground and the excavation equipment is working with a lot of dust, the adjustment component 209 is adjusted to the support 205, so that the pumping component 208 can drive the nozzle 204 to rotate back and forth during operation, thereby increasing the spray coverage area, saving water and increasing the dust reduction effect. When there are few rocks underground and the excavation equipment is working with a little dust, the adjustment component 209 is adjusted to the support 205, so that the pumping component 208 does not drive the nozzle 204 to rotate during operation, thereby reducing the wear of the device.

[0026] Furthermore, the driving assembly 207 includes a driving motor 207a fixedly mounted on the bracket 206, and the output end of the driving motor 207a is connected to a cam 207b, and the cam 207b is divided into a protruding end and an arc end; The driving motor 207a is selected to be a motor that can control the rotation speed, that is, a motor that controls the rotation speed of the cam 207b.

[0027] Furthermore, the pumping assembly 208 includes a first check piece 208a and a second check piece 208b disposed inside the through pipe 202. The first check piece 208a is fixedly connected to a concave frame 208c, and the concave frame 208c is fixedly connected to a vertical plate 208d. A side of the vertical plate 208d close to the cam 207b is connected to a roller 208e, and the surface of the roller 208e is also an arc surface. The first check piece 208a and the second check piece 208b are the same. The provision of the first check member 208a also ensures that the vertical plate 208d can only move vertically, thereby ensuring that the positions of the roller 208e and the cam 207b correspond.

[0028] Further, the first check member 208a includes a piston 208a-1 disposed inside the through pipe 202, a through port 208a-2 is formed on the piston 208a-1, a cover 208a-3 is rotatably connected to the piston 208a-1, the cover 208a-3 matches the through port 208a-2, so that the cover 208a-3 can completely block the through port 208a-2, the piston 208a-1 on the first check member 208a is slidably connected to the through pipe 202, and the piston 208a-1 on the second check member 208b is fixedly connected to the through pipe 202; The piston 208a-1 and the through tube 202 are both rectangular, so that the first check member 208a can only move vertically up and down but cannot rotate.

[0029] In the initial state, the arc end of the cam 207b contacts the bottom of the roller 208e; When the cutter head 102 is cutting the underground rock, a large amount of crushed stone and dust are generated during the cutting process, which are transported by the screw conveyor 103 and input to the conveyor belt 104 through the discharge port of the screw conveyor 103. There will be a large amount of dust at the discharge port (the dust comes from the cutting of the underground rock by the cutter head 102 and the collision between crushed stones when the screw conveyor 103 is transporting the crushed stone); By turning on the driving motor 207a, the driving motor 207a drives the cam 207b to rotate. When the protruding end of the cam 207b approaches the bottom of the roller 208e, it drives the roller 208e to rise. The roller 208e drives the vertical plate 208d to rise. The vertical plate 208d drives the first check piece 208a connected thereto to rise through the concave frame 208c. At this time, the piston 208a-1 on the first check piece 208a is in a closed state due to the influence of air pressure. During the rising process of the first check piece 208a, a negative pressure is formed between the first check piece 208a and the second check piece 208b, so that the sealing cover 208a-3 on the second check piece 208b is opened, and the water inside the water tank 201 passes through the first check piece 208a-1. The opening 208a-2 on the second check piece 208b flows to the top of the second check piece 208b. When the arc end of the cam 207b approaches the bottom of the roller 208e, the first check piece 208a descends under the action of the gravity of the first check piece 208a, the concave frame 208c and the vertical plate 208d. A positive pressure is formed between the first check piece 208a and the second check piece 208b. The cover 208a-3 on the second check piece 208b is reset, and the cover 208a-3 on the first check piece 208a is opened. The water between the first check piece 208a and the second check piece 208b flows to the top of the first check piece 208a through the opening 208a-2 on the first check piece 208a. When the protruding end of the cam 207b continues to rotate toward the bottom of the roller 208e, the water on the top of the first check member 208a cannot flow down due to the closure of the upper cover 208a-3 of the first check member 208a. When the first check member 208a rises, the water on the first check member 208a rises and flows to the water pipe 203, flows to the nozzle 204 through the water pipe 203, and is sprayed out through the nozzle 204 to achieve dust disposal.

[0030] In summary, the first check member 208a relies on the effect of gravity when resetting, which is different from many prior arts that rely on thrust to push the first check member 208a to reset. It is only necessary to ensure that the speed at which the drive motor 207a drives the cam 207b to rotate is slightly greater than the speed at which the roller 208e descends, so as to reduce the contact time between the cam 207b and the roller 208e and reduce the wear between the cam 207b and the roller 208e. At the same time, since most of the water spray dust removal in the prior art uses the atomizing nozzle 204, that is, the required amount of water is not large, when the device is running, the first check member 208a does not need to return to the initial position, and the drive motor 207a drives the protruding end of the cam 207b to change the distance from the bottom of the roller 208e to be greater than the change in the distance of the first check member 208a falling (that is, when the drive motor 207a When the protruding end of the cam 207b is at the bottom, the arc end of the cam 207b corresponds to the position of the roller 208e, but the roller 208e is at the top of the arc end, but there is still a certain distance from the arc end. If the driving motor 207a is turned off at this time, the cam 207b is no longer rotating, and the first check member 208a will continue to descend until the roller 208e contacts the arc end of the cam 207b and returns to the initial position. If the driving motor 207a is not turned off at this time, the driving motor 207a continues to drive the cam 207b to rotate, and the protruding end of the cam 207b will move upward, that is, when the first check member 208a has not returned to the initial position, the cam 207b facilitates contact with the bottom of the roller 208e), reducing the range of movement of the first check member 208a and reducing the wear between the first check member 208a and the through pipe 202.

[0031] Example 2, reference Figures 2 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, the adjustment component 209 in this embodiment includes a ring sleeve 209a fixedly mounted on the pillar 205, and a track groove 209b is provided on the ring sleeve 209a. A driving rod 209c is connected to the side of the vertical plate 208d away from the cam 207b, and the end of the driving rod 209c away from the vertical plate 208d is hemispherical.

[0032] Furthermore, the track groove 209b includes a first driving groove 209b-1, a vertical groove 209b-2 and a second driving groove 209b-3 which are formed on the ring sleeve 209a. The first driving groove 209b-1 is in a "V" shape after being rotated 90 degrees, and the second driving groove 209b-3 is in a "W" shape after being rotated 90 degrees. Among them, the angle occupied by the first driving groove 209b-1 and the second driving groove 209b-3 from a top view is less than one hundred and eighty degrees, avoiding the first driving groove 209b-1, the vertical groove 209b-2 or the second driving groove 209b-3 from being connected.

[0033] Furthermore, the corners of the first driving groove 209b-1 and the second driving groove 209b-3 are both arc surfaces; The setting of the arc surface makes it easier for the driving rod 209c to drive the support 205 to rotate.

[0034] The rest of the structure is the same as that of Example 1.

[0035] In this embodiment, the nozzle 204 and the support 205 are connected by a clamp or other connection methods that can fix the nozzle 204 in the initial position after the support rotates; In this embodiment, in the initial state, the driving rod 209c can be located at the top or the bottom of the ring sleeve 209a, depending on whether the protruding end or the arc end of the cam 207b contacts the roller 208e. If the protruding end contacts the roller 208e, the driving rod 209c is located at the top of the ring sleeve 209a, and if the arc end contacts the roller 208e, the driving rod 209c is located at the bottom of the ring sleeve 209a. The track groove 209b is not limited to the first driving groove 209b-1, the vertical groove 209b-2 and the second driving groove 209b-3, and can also be a track groove 209b of other shapes, such as a wave shape, etc. This solution only describes several necessary ones; In this embodiment, the connection between the nozzle 204 and the support 205 is first loosened, and then the support is adjusted according to the underground conditions; When there are many rocks on the ground and the soil moisture is normal (the moisture is between 40% and 60%), the cutter head 102 generates more dust when it is in use. At this time, the first driving groove 209b-1 on the column is rotated to correspond to the position of the driving rod 209c. When the cam 207b drives the vertical plate 208d to move through the roller 208e, and the vertical plate 208d drives the driving rod 209c to move, the driving rod 209c enters the first driving groove 209b-1, and moves inside the "V"-shaped first driving groove 209b-1 after rotating ninety degrees. By contacting the inner wall of the first driving groove 209b-1, the column is driven to rotate back and forth, which greatly increases the spray coverage area, saves water resources and improves the dust reduction effect. When there are fewer rocks on the ground and the soil is relatively moist (humidity is greater than 60%), the cutter head 102 generates less dust when in use. At this time, the vertical slot 209b-2 on the column is aligned with the position of the drive rod 209c. When the cam 207b drives the drive rod 209c to move through the roller 208e and the vertical plate 208d, the drive rod 209c enters the vertical slot 209b-2 without contacting the inner wall of the vertical slot 209b-2, and will not drive the column to rotate, so that the nozzle 204 can spray and reduce dust normally, reducing the wear of the device; When there are many rocks on the ground and the soil is relatively dry (humidity is less than 40%), a large amount of dust will be generated when the cutter disc 102 is in use. The second driving groove 209b-3 on the column will correspond to the position of the driving rod 209c. When the cam 207b drives the driving rod 209c to move through the roller 208e and the vertical plate 208d, the driving rod 209c enters the second driving groove 209b-3, and moves inside the "W"-shaped second driving groove 209b-3 after rotating ninety degrees. By contacting the inner wall of the second driving groove 209b-3, the column is driven to rotate back and forth multiple times, covering a larger area in a short time, and quickly reducing the dust concentration.

[0036] In summary, by setting the track groove 209b on the ring sleeve 209a, the track groove 209b is divided into a first driving groove 209b-1, a vertical groove 209b-2 and a second driving groove 209b-3, so that the device can be used in a variety of different environments, increasing the spray range, saving water resources, and increasing the practicality of the device, so that the device can be used in different terrains.

[0037] Example 3, reference Figures 2 to 5 , which is the third embodiment of the present invention. Different from the previous embodiment, the adjustment component 209 in this embodiment also includes a circular sleeve 209d fixedly mounted on the pillar 205, and a spring 209e is also mounted on the pillar 205. One end of the spring 209e is fixedly connected to the circular sleeve 209d, and the other end of the spring 209e is fixedly connected to the limiting sleeve 209f. An annular groove 209g is formed between the limiting sleeve 209f and the annular sleeve 209a, and the first driving groove 209b-1, the vertical groove 209b-2 and the second driving groove 209b-3 are all connected to the annular groove 209g.

[0038] Furthermore, the adjustment component 209 further includes a plurality of positioning grooves 209h provided on the pillar 205, and positioning blocks 209i are disposed inside the plurality of positioning grooves 209h, and the plurality of positioning blocks 209i are fixedly connected to the limiting sleeve 209f; Among them, the circular sleeve 209d, the spring 209e and the limit sleeve 209f are all located at the top of the ring sleeve 209a, and the multiple positioning grooves 209h are also located at the top of the ring sleeve 209a. The setting of the multiple positioning grooves 209h ensures that the limit slot can only move linearly in the vertical direction, and in the initial state, the positioning block 209i contacts the inner wall at the bottom of the positioning groove 209h to support the limit sleeve 209f, and then support the spring 209e, so that the spring 209e does not bear the pulling force on the limit sleeve 209f in the initial state, thereby increasing the service life of the spring 209e.

[0039] Furthermore, the positioning block 209i is in the shape of a letter "7", with its horizontal section located inside the positioning groove 209h, and its vertical section located outside the positioning groove 209h and fixedly connected to the inner ring of the limiting sleeve 209f, the vertical section of the positioning block 209i is in contact with the outer surface of the pillar 205, and the end of the vertical section of the positioning block 209i is in contact with the top of the ring sleeve 209a; Among them, multiple positioning blocks 209i are respectively located at the slots of the first driving slot 209b-1, the vertical slot 209b-2 and the second driving slot 209b-3. The setting of multiple positioning blocks 209i also limits the movement of the driving rod 209c to avoid shaking when adjusting to a suitable slot corresponding to the driving rod 209c, causing the support 205 to rotate, thereby changing the slot corresponding to the driving rod 209c, and further affecting the spraying range of the nozzle 204.

[0040] Different from the above embodiment, in this embodiment, in the initial state, the driving rod 209c is located inside the annular groove 209g, and the protruding end of the cam 207b is in contact with the roller 208e; The rest of the structure is the same as that of Example 2.

[0041] When it is necessary to change the soil according to the rock content and soil moisture content inside the soil, first push the limit sleeve 209f up, the limit sleeve 209f drives the spring 209e to be compressed, and at the same time, the limit sleeve 209f drives the positioning block 209i to move upward along the positioning groove 209h, so that the vertical section of the positioning block 209i is misaligned with the driving rod 209c. At this time, the limit sleeve 209f can be directly rotated, and the limit sleeve 209f drives the support 205 to rotate through the positioning block 209i and the positioning groove 209h, and the support 205 drives the ring sleeve 209a to rotate. When the appropriate track groove 209b corresponds to the driving rod 209c, release your hand and the limit sleeve 209f will rotate. 09f Under the action of gravity and the elastic force of spring 209e, the positioning block 209i returns to the initial position. At this time, the end of the driving rod 209c corresponds to the slot position of the corresponding track slot 209b, and is located between the two corresponding positioning blocks 209i. When the device is vibrated, the column will rotate, and the column will drive the two positioning blocks 209i thereon to rotate. The two positioning blocks 209i drive the driving rod 209c to rotate. Under the restriction of the first check piece 208a, the driving rod 209c cannot rotate. Therefore, when the device is running, the column will not rotate due to shaking, which will change the spraying range of the nozzle 204, thereby reducing the dust reduction effect.

[0042] In summary, this embodiment further optimizes the scheme. What is different from the second embodiment is that in the second embodiment, although different trajectory grooves 209b can also be changed to correspond to the drive rod 209c, when the cam 207b is in a vertical state, the drive rod 209c is not located in the corresponding trajectory groove 209b. Since the cutter head 102 will inevitably vibrate to a certain extent during the process of cutting the rock and the operation of the device, when vibration occurs, if the drive rod 209c is not located in the trajectory groove 209b, the drive rod 209c will not limit the column. At this time, the column can rotate, thereby affecting the dust reduction effect. This scheme solves this problem by setting a limit sleeve 209f and multiple positioning blocks 209i. The limit sleeve 209f and multiple positioning blocks 209i are equivalent to multiple caps, which are equivalent to extensions of the trajectory groove 209b.
