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.

During the normal operation of the drive motor 8 and the mist 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 drive motor 8 stops working, due to the reverse reset force of the connecting torsion spring 92, the second transmission shaft 94 is reversed, and the second transmission bevel gear group 141, the third transmission shaft 142 and the second ratchet body 143 drive the fourth transmission shaft 144 to rotate. When the fourth transmission shaft 144 rotates, the rotating disk 145 fixed to the surface of the fourth transmission shaft 144 can drive the pull rope 146 to work.

[0039] 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-bearing 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 to the pull rope 146.

[0041] The stabilizing mechanism 17 includes a second connecting tube 171 connected to the surfaces of the first connecting tubes 114 on both sides, the other end of the second connecting tube 171 is connected to the second constant pressure tube 172, the surface of the second constant pressure tube 172 is connected to a plurality of third piston tubes 173, the inner cavity of the third piston tube 173 is slidably provided with a third piston head 174, the other end of the third piston head 174 is fixed with a third piston rod 175, the other end of the third piston rod 175 is fixed with a connecting plate 176, the surface of the connecting plate 176 is slid with a plurality of buffer slides 177, the other end of the buffer slide 177 is fixed with a stabilizing plate 178, the surface of the buffer slide 177 is sleeved with a tension spring 179, one end of the tension spring 179 is fixed to the surface of the buffer slide 177, and the other end of the tension spring 179 is fixed to the surface of the connecting plate 176.

[0042] In this embodiment, through the arrangement of the second connecting tube 171, the second constant pressure tube 172, the third piston tube 173, the third piston head 174, the third piston rod 175, the connecting plate 176, the buffer slide bar 177, the stabilizing plate 178 and the tension spring 179, when the first connecting tube 114 is working, the air pressure in the second connecting tube 171 can also change, and then under the action of the second connecting tube 171, the second constant pressure tube 172 can work, and the third piston tube 173 in the inner cavity of the second constant pressure tube 172 can make the third piston head 174 drive the third piston rod 175 to move, so that under the connection of the tension spring 179, the stabilizing plate 178 is in contact with the ground. In addition, after the stabilizing plate 178 is in contact with the ground, due to the excessive ground resistance, the tension spring 179 is stretched, so that the stabilizing plate 178 and the buffer slide bar 177 slide relative to the connecting plate 176, thereby achieving the purpose of providing auxiliary buffering for the operation of the protective mechanism 12.

[0043] Working principle: During the earth excavation of water conservancy river channels, a certain amount of dust will be generated due to the earth excavation. A fog cannon is needed to suppress the dust. The staff can use the universal wheel 2 on the surface of the support seat 1 to place the device in the working area, and then suppress the dust under the action of the drive motor 8, the feeding pipe 5, the fog fan 19, the water circle block 6 and the atomizing head 7.

[0044] When the drive motor 8 is working, the first transmission shaft 91 fixed on the output shaft of the drive motor 8 can rotate, thereby causing the connecting torsion spring 92 to twist. After the connecting torsion spring 92 is twisted to a certain extent, the second transmission shaft 94 can rotate, thereby causing the mist delivery fan 19 to work. 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.

[0045] When the first transmission shaft 91 rotates, the first transmission bevel gear set 101 arranged on the surface of the first transmission shaft 91 can make the first transmission rods 102 on both sides rotate, and then under the action of the first ratchet body 103, the second transmission rod 104 can work, and the protrusion 105 fixed on one side of the surface of the second transmission rod 104 can fit between the force-bearing head 106. Since the protrusion 105 is composed of three small blocks and one large block, the protrusion 105 can squeeze the force-bearing head 106 into three small paths and one large path, so that the force-bearing head 106 moves with different amplitudes. When the force-bearing head 106 moves in a small path, the driving block 125 can drive the brush 126 to clean the surface of the atomizer head 7 under the action of the starting mechanism 11. When the force-bearing head 106 moves in a large path, the locking groove 153 can be located at the lower side of the insertion block 152, and the insertion block 152 can be inserted into the locking groove 153, thereby achieving the purpose of stabilizing the protective mechanism 12.

[0046] Furthermore, when the force-bearing head 106 moves a small path, the insertion needle 18 can reciprocate and pierce the ground under the action of the stabilizing mechanism 17, thereby improving the stability of the connection between the insertion needle 18 and the ground. When the force-bearing head 106 moves a large path, the stabilizing plate 178 and the insertion needle 18 can be stably attached to the ground, thereby achieving the effect of stabilizing the support seat 1 and avoiding unstable operation of the support seat 1 due to vibration generated by earth excavation.

[0047] After the excavation is completed, the driving 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 begins to reset, and then under the reset force of the connecting torsion spring 92, the second transmission shaft 94 is reversed, and further the second transmission bevel gear group 141, the third transmission shaft 142 and the second ratchet body 143 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.

[0048] As the rotating disk 145 drives the pull rope 146 to rotate, the pull rope 146 is tightened, so that the pull rope 146 can stretch the connecting rod 151, thereby making the insertion block 152 disengage from the locking groove 153, releasing the restriction on the force-bearing head 106. After the insertion block 152 moves up, under the action of the third reset spring 155, the insertion block 152 is again attached to the surface of the force-bearing head 106, so that it can participate in the next work. After the force-bearing head 106 is not restricted, it can move toward the protrusion 105 under the reset force of the second reset spring 134 and the first reset spring 113, so that the pressure in the first piston tube 112 changes again, so as to achieve the purpose of resetting the drive block 125 and the stabilizing plate 178, so that it is convenient for the next work.
