Description

Technical Field

[0001] The invention relates to the technical field of atomization dust reduction, and in particular to earth excavation and dust reduction equipment used in water conservancy river channel construction. Background Art

[0002] Water conservancy river construction refers to a comprehensive engineering activity of regulating, building and maintaining the river in accordance with the planning and design requirements of water conservancy projects, aiming to ensure the smooth discharge of flood water and enhance flood control effects. Earthwork excavation and transportation dust reduction equipment is a special equipment equipped to reduce dust during earthwork excavation and transportation, such as fog cannon dust reduction equipment, which effectively suppresses dust diffusion through water sprinkling and spraying, improves the construction environment, and realizes green construction.

[0003] Mist cannon dust suppression equipment is a device that atomizes liquid and acts on the surface of dust particles. Since water conservancy river excavation generates a lot of dust, there is still some dust in the air after the excavation is completed, and there is still a certain amount of moisture on the surface of the atomization port. Dust can easily adhere to the surface of the atomization head through the moisture. If it is not used for a long time, the equipment may be blocked, affecting its use. In addition, during earth excavation, the ground will produce a certain vibration, which will affect the stability of the equipment. Summary of the invention

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 13 As shown, an earthwork excavation, transportation and dust reduction device for water conservancy river channel construction includes a support base 1. The surface of the support base 1 is provided with a number of universal wheels 2 for movement. The surface of the support base 1 is provided with a steering mechanism body 3 for adjustment. The surface of the steering mechanism body 3 is provided with a fog cannon barrel 4. One side of the surface of the fog cannon barrel 4 is communicated with a feeding pipe 5 in the inner cavity of the support base 1. One side of the surface of the fog cannon barrel 4 is provided with a water ring block 6. The surface of the water ring block 6 is communicated with a number of atomizing heads 7. A driving motor 8 is fixed in the inner cavity of the fog cannon barrel 4. The driving motor 8 is drivingly connected to a transmission mechanism 9 for driving. The output end of the transmission mechanism 9 is drivingly connected to a fog blowing fan 19 for blowing atomized water. It further includes;

[0037] A drive mechanism 10 is provided on one side of the surface of the transmission mechanism 9. On the other side of the drive mechanism 10, a starting mechanism 11 is provided. On the other side of the starting mechanism 11, a protection mechanism 12 for protecting the atomizing head 7 is provided. On the surface of the protection mechanism 12, a limiting mechanism 13 for limiting the protection mechanism 12 is provided;

[0038] A pulling mechanism 14 is provided on the other side of the surface of the transmission mechanism 9. On one side of the pulling mechanism 14, a locking mechanism 15 for restricting the use of the drive mechanism 10 is provided. On both sides of the surface of the fog cannon barrel 4, limiting members 16 for restricting the use of the locking mechanism 15 are fixed;

[0039] A stabilizing mechanism 17 for stably supporting the support base 1 is provided on the surface of the support base 1. An insertion needle 18 is provided on the surface of the stabilizing mechanism 17.

[0040] When the present invention operates this device, when the drive motor 8 drives the fog delivery fan 19 to rotate through the transmission mechanism 9, the transmission mechanism 9 drives the drive mechanism 10 to work. Then, under the action of the starting mechanism 11, the protection mechanism 12 cleans the atomizing head 7. And with the setting of the starting mechanism 11 structure, after the drive motor 8 stops working, the atomizing head 7 can be protected.

[0041] In addition, under the action of the transmission mechanism 9, the stabilizing mechanism 17 can be stably connected to the ground, thereby improving the practicability of this device. In addition, after the drive motor 8 stops working, under the action of the transmission mechanism 9, the pulling mechanism 14 drives the locking mechanism 15 to reset the drive mechanism 10, which is convenient for the next operation.

[0042] The transmission mechanism 9 includes a first transmission shaft 91 fixed to one side of the output shaft of the drive motor 8. A plurality of connecting torsion springs 92 are fixed to the surface of the first transmission shaft 91. The other end of the connecting torsion spring 92 is fixed to a second transmission shaft 94. The fog delivery fan 19 is fixed to the other end of the second transmission shaft 94. A limiting column 93 is rotatably arranged in the inner cavity of the second transmission shaft 94. The other end of the limiting column 93 is fixed to the surface of the first transmission shaft 91.

[0043] In this embodiment, through the setting of the first transmission shaft 91, the connecting torsion spring 92, the limiting column 93 and the second transmission shaft 94, when the drive motor 8 works, the first transmission shaft 91 fixed to the output shaft of the drive motor 8 can rotate, thereby twisting the connecting torsion spring 92. After the connecting torsion spring 92 is twisted to a certain extent, the second transmission shaft 94 can be made to rotate, so that the fog delivery fan 19 works. Under the action of the limiting column 93, the transmission stability between the first transmission shaft 91 and the second transmission shaft 94 can be improved.

[0044] The driving mechanism 10 includes a first transmission bevel gear set 101 arranged on the first transmission shaft 91. On both sides of the other end of the first transmission bevel gear set 101, first transmission rods 102 are drivingly arranged. At the other end of the first transmission rod 102, a first ratchet body 103 is fixed. At the other end of the first ratchet body 103, a second transmission rod 104 is fixed. At the other end of the second transmission rod 104, a convex block 105 is fixed. The outer peripheral surface of the convex block 105 is in fitting contact with a force-receiving head 106.

[0045] In this embodiment, through the arrangement of the first transmission bevel gear set 101, the first transmission rods 102, the first ratchet body 103, the second transmission rods 104, the convex block 105 and the force-receiving head 106, when the driving motor 8 is working normally, the first transmission shaft 91 rotates. The first transmission bevel gear set 101 arranged on the surface of the first transmission shaft 91 can cause the first transmission rods 102 on both sides to rotate. Then, under the action of the first ratchet body 103, the second transmission rod 104 works. The convex block 105 fixed on one side of the surface of the second transmission rod 104 can fit with the force-receiving head 106.

[0046] It should be noted that in this application, the ratchet is a prior art and can perform one-way transmission, which will not be elaborated here.

[0047] Raised portions are provided at the four corners of the convex block 105, and three of the raised portions are of the same size and are all smaller than the other raised portion.

[0048] In this embodiment, through this arrangement, the extrusion of the convex block 105 on the force-receiving head 106 can be three small paths and one large path, causing the force-receiving head 106 to move in different amplitudes.

[0049] The starting mechanism 11 includes a first piston head 111 fixed to one side of the force-receiving head 106. A first piston tube 112 is slidably arranged on the surface of the first piston head 111. On one side of the inner cavity of the first piston tube 112, a first return spring 113 is fixed. The other end of the first return spring 113 is fixed to the surface of the first piston head 111. A first connecting pipe 114 is communicated with the surface of the first piston tube 112. The other end of the first connecting pipe 114 is communicated with a first constant-pressure pipe 115.

[0050] In this embodiment, through the arrangement of the first piston head 111, the first piston tube 112, the first return spring 113, the first connecting pipe 114 and the first constant-pressure pipe 115, when the force-receiving head 106 moves, the first piston head 111 can slide in the inner cavity of the first piston tube 112, thereby causing the pressure in the inner cavity of the first piston tube 112 to change. Under the action of the first connecting pipe 114, the first constant-pressure pipe 115 drives the protection mechanism 12 to work.

[0051] The protection mechanism 12 includes a plurality of first connection blocks 121 fixed to one side of the surface of the fog cannon barrel 4. A second piston tube 122 is fixed inside the cavity of the first connection block 121. One end of the second piston tube 122 communicates with the first constant pressure tube 115. A second piston head 123 is slidably arranged inside the second piston tube 122. The other end of the second piston head 123 is fixed with a second piston rod 124. The other end of the second piston rod 124 is fixed with a driving block 125. A brush 126 is fixed to the surface of the driving block 125.

[0052] In this embodiment, through the arrangement of the first connection block 121, the second piston tube 122, the second piston head 123, the second piston rod 124, the driving block 125 and the brush 126, since the first connection tube 114 communicates with the side of the inner cavity of the second piston tube 122 close to the driving block 125, when there is air flow in the first constant pressure tube 115, the pressure inside the first connection block 121 can be changed, and then the second piston head 123 in the second piston tube 122 can move the second piston rod 124, so that the driving block 125 drives the brush 126 to move. Due to the arrangement of the convex block 105 structure, the brush 126 can clean the atomizing head 7 multiple times, and during a large-path displacement, the driving block 125 can be hidden in the first connection block 121 to provide space for the operation of the atomizing head 7.

[0053] It should be noted that an exhaust hole is provided in the upper cavity of the second piston tube 122, and a filter cover is arranged on the surface of the exhaust hole, as Figure 10 shown.

[0054] The limiting mechanism 13 includes second connection blocks 131 fixed to both sides of the surface of the driving block 125. A limiting block 132 is fixed to one side of the second connection block 131. A limiting slide rod 133 is slidably arranged inside the cavity of the limiting block 132. A second return spring 134 is sleeved on the surface of the limiting slide rod 133. One end of the second return spring 134 is fixed to the surface of the limiting block 132, and the other end of the second return spring 134 is fixed to the inner cavity of the first connection block 121.

[0055] In this embodiment, through the arrangement of the second connection block 131, the limiting block 132, the limiting slide rod 133 and the second return spring 134, when the driving block 125 moves, the second connection blocks 131 and the limiting blocks 132 fixed to both sides of the surface of the driving block 125 can slide on the surface of the limiting slide rod 133, and under the action of the second return spring 134, a limiting and resetting force is provided for the sliding of the limiting block 132.

[0056] The pulling mechanism 14 includes a second transmission bevel gear set 141 that is transmitted on the surface of the second transmission shaft 94. The other end of the second transmission bevel gear set 141 is fixed with a third transmission shaft 142. The other end of the third transmission shaft 142 is fixed with a second ratchet body 143. The other end of the second ratchet body 143 is fixed with a fourth transmission shaft 144. The other end of the fourth transmission shaft 144 is fixed with a rotating disk 145. Both sides of the surface of the rotating disk 145 are fixed with pulling ropes 146.

[0057] In this embodiment, through the arrangement of the second transmission bevel gear set 141, the third transmission shaft 142, the second ratchet body 143, the fourth transmission shaft 144, the rotating disk 145 and the pulling ropes 146, when the second transmission shaft 94 rotates, under the action of the second transmission bevel gear set 141, the third transmission shaft 142 can be rotated. During the normal operation of the driving motor 8 and the fog delivery fan 19, the rotation of the third transmission shaft 142 will not be transmitted to the fourth transmission shaft 144 through the second ratchet body 143. When the driving motor 8 stops working, due to the reverse reset force of the connecting torsion spring 92, the second transmission shaft 94 will rotate in the reverse direction, and further the second transmission bevel gear set 141, the third transmission shaft 142 and the second ratchet body 143 will drive the fourth transmission shaft 144 to rotate. When the fourth transmission shaft 144 rotates, the rotating disk 145 fixed on the surface of the fourth transmission shaft 144 can drive the pulling ropes 146 to work.

[0058] The locking mechanism 15 includes a connecting rod 151 that slides in the inner cavity of the limiting member 16 and a locking groove 153 opened on the surface of the force receiving head 106. The other end of the connecting rod 151 is fixed with an insertion block 152. One end of the connecting rod 151 is fixed with the pulling rope 146. Both sides of the surface of the insertion block 152 are fixed with limiting rods 154. Both sides of the surface of the insertion block 152 are fixed with third return springs 155. The other end of the third return springs 155 is fixed on the surface of the limiting member 16. The third return springs 155 are sleeved on the surfaces of the limiting rods 154. The limiting rods 154 slide in the inner cavity of the limiting member 16.

[0059] In this embodiment, through the arrangement of the connecting rod 151, the insertion block 152, the locking groove 153, the limiting rods 154 and the third return springs 155, under the action of the third return springs 155 and the limiting member 16, the insertion block 152 can move downward. Then, when the locking groove 153 is below the insertion block 152, the insertion block 152 can be inserted into the locking groove 153. When the pulling rope 146 is pulled, the insertion block 152 can be separated from the locking groove 153, thereby releasing the restriction on the force receiving head 106.

[0060] The stabilizing mechanism 17 includes a second connecting pipe 171 connected to the surfaces of the first connecting pipes 114 on both sides. The other end of the second connecting pipe 171 is connected to a second constant-pressure pipe 172. A number of third piston pipes 173 are connected to the surface of the second constant-pressure pipe 172. A third piston head 174 is slidably arranged in the inner cavity of the third piston pipe 173. The other end of the third piston head 174 is fixed to a third piston rod 175. The other end of the third piston rod 175 is fixed to a connecting plate 176. A number of buffer sliding rods 177 are slidably arranged on the surface of the connecting plate 176. The other end of the buffer sliding rod 177 is fixed to a stabilizing plate 178. A tension spring 179 is sleeved on the surface of the buffer sliding rod 177. One end of the tension spring 179 is fixed to the surface of the buffer sliding rod 177, and the other end of the tension spring 179 is fixed to the surface of the connecting plate 176.

[0061] In this embodiment, through the arrangement of the second connecting pipe 171, the second constant-pressure pipe 172, the third piston pipe 173, the third piston head 174, the third piston rod 175, the connecting plate 176, the buffer sliding rod 177, the stabilizing plate 178 and the tension spring 179, when the first connecting pipe 114 is working, the air pressure in the second connecting pipe 171 can also change. Then, under the action of the second connecting pipe 171, the second constant-pressure pipe 172 starts to work. The third piston pipe 173 in the inner cavity of the second constant-pressure pipe 172 can make the third piston head 174 drive the third piston rod 175 to move. Thus, under the connection of the tension spring 179, the stabilizing plate 178 is attached to the ground. In addition, after the stabilizing plate 178 is attached to the ground, due to the excessive ground resistance, the tension spring 179 is stretched, and the stabilizing plate 178 and the buffer sliding rod 177 slide relative to the connecting plate 176, achieving the purpose of providing auxiliary buffering for the work of the protection mechanism 12.

[0062] Working principle: During the excavation of soil in a water conservancy river channel, due to the soil excavation, a certain amount of dust will be generated. Therefore, a fog cannon machine is needed to reduce the dust. The staff can use the universal wheels 2 on the surface of the support base 1 to place the device in the working area. Then, under the action of the drive motor 8, the feeding pipe 5, the fog-sending fan 19, the water ring block 6 and the atomizing head 7, the dust is reduced.

[0063] When the drive motor 8 is working, the first transmission shaft 91 fixed to the output shaft of the drive motor 8 can rotate, and then the connecting torsion spring 92 is twisted. After the connecting torsion spring 92 is twisted to a certain extent, the second transmission shaft 94 can rotate, so that the fog-sending fan 19 starts to work. Under the action of the limit post 93, the transmission stability between the first transmission shaft 91 and the second transmission shaft 94 can be improved.

[0064] When the first transmission shaft 91 rotates, the first transmission bevel gear set 101 disposed on the surface of the first transmission shaft 91 can cause the first transmission rods 102 on both sides to rotate. Further, under the action of the first ratchet body 103, the second transmission rod 104 can be made to work. The convex block 105 fixed on one side of the surface of the second transmission rod 104 can be in contact with the force-receiving head 106. Since the convex block 105 is composed of three small blocks and one large block, the convex block 105 can exert pressure on the force-receiving head 106 in three small paths and one large path, causing the force-receiving head 106 to move in different amplitudes. When the force-receiving head 106 moves in a small path, under the action of the starting mechanism 11, the driving block 125 can drive the brush 126 to clean the surface of the atomizing head 7. When the force-receiving head 106 moves in a large path, the locking groove 153 can be positioned below the insertion block 152, allowing the insertion block 152 to be inserted into the locking groove 153, achieving the purpose of stabilizing the protection mechanism 12.

[0065] And when the force-receiving head 106 moves in a small path, under the action of the stabilizing mechanism 17, the insertion needle 18 can reciprocally pierce the ground, thereby improving the stability of the connection between the insertion needle 18 and the ground. When the force-receiving head 106 moves in a large path, the stabilizing plate 178 and the insertion needle 18 can stably fit the ground, thereby achieving the effect of stabilizing the support base 1 and preventing the support base 1 from working unstably due to vibrations generated during earth excavation.

[0066] After the earth excavation is completed, the drive motor 8 stops working. After the rotational inertia of the second transmission shaft 94 and the first transmission shaft 91 ends, the connecting torsion spring 92 starts to reset. Further, under the resetting force of the connecting torsion spring 92, the second transmission shaft 94 rotates in the reverse direction, further causing the second transmission bevel gear set 141, the third transmission shaft 142, and the second ratchet body 143 to drive the fourth transmission shaft 144 to rotate. When the fourth transmission shaft 144 rotates, the rotating disk 145 fixed on the surface of the fourth transmission shaft 144 can drive the pull rope 146 to work.

[0067] Since the rotating disk 145 drives the pull rope 146 to rotate, the pull rope 146 becomes taut, enabling the pull rope 146 to stretch the connecting rod 151. As a result, the insertion block 152 disengages from the locking groove 153, releasing the restriction on the force-receiving head 106. After the insertion block 152 moves upward, under the action of the third return spring 155, the insertion block 152 is repositioned to fit the surface of the force-receiving head 106, enabling it to participate in the next operation. After the force-receiving head 106 is no longer restricted, under the resetting forces of the second return spring 134, the first return spring 113, etc., it moves towards the convex block 105, causing the pressure in the first piston tube 112 to change again, achieving the purpose of resetting the driving block 125 and the stabilizing plate 178 and facilitating their next operation.
