DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-6As shown, a portable spray dust removal device for manual bored pile construction site, a water storage tank 1 as a storage device for spray dust removal, storing water for dust reduction, a connection seat 2 is installed at the top end of the water storage tank 1. A cylindrical cavity is opened inside the connection seat 2, and the cylindrical cavity is connected to the external pipeline to realize water supply; a booster pump out structure arranged on one side of the connection seat 2 realizes the effect of booster spraying, and accurately reduces dust at the construction site of the manual bored pile.

[0027] The booster pump-out structure includes a pump housing 3 integrally formed with the connection seat 2, a booster impeller 4 installed in the pump housing 3, a power assembly 5 that is linked with the engineering machinery and is used to drive the booster impeller 4 to rotate, and a detachable connector 8 connecting the power assembly 5 and the booster impeller 4. During use, when the engineering machinery is held by a person, the torque of the rotating shaft of the engineering machinery such as an impact drill will be wasted during the rotation process except for being output to the drill bit for drilling. By linking the power assembly 5, the power assembly 5 drives the booster impeller 4 to rotate, so that the booster impeller 4 rotates in the pump housing 3. Since the pump housing 3 is connected to the inner cavity of the connection seat 2, the booster impeller 4 pressurizes and sprays the dust reduction water. Moreover, due to the transmission with the rotating shaft of the engineering machinery, the power of the booster pump-out structure does not need to be external, which reduces power consumption, is cleaner and more environmentally friendly, and reduces the weight of the engineering machinery held by the staff.

[0028] The water tank 1 is preferably a 304 stainless steel bottle, and an observation port is provided on one side of the outer wall of the water tank 1, and an observation glass 13 is provided on the observation port. The water tank 1 adopts a bottled water structure, which can be disassembled and assembled by the connection seat 2 on the water tank 1, so as to facilitate water replenishment. On the other hand, the structure is compact, which is convenient for parallel connection and arrangement with engineering machinery without affecting the use of the operator. This also means that during construction, the dust reduction device can be synchronously brought under the pile hole, so that the dust reduction operation can be carried out closer to the user.

[0029] In order to enable the dust suppression device to more intuitively suppress dust in the pile hole, a pipe interface 61 is provided at the top of the connecting seat 2, and an extension pipeline 6 is connected to the pipe interface 61. The extension pipeline 6 adopts a retractable sealed tube body, and a rotating seat 62 is provided at the end of the extension pipeline 6. The rotating seat 62 is connected to a pressurized atomizing nozzle 7. One end of the extension pipeline 6 is fixedly connected through the pipe interface 61, and water is sent to the pressurized atomizing nozzle 7 on the rotating seat 62 through the extension pipeline 6. The pressurized atomizing nozzle 7 is a water mist nozzle with an atomization angle and is threadedly connected to the head end of the rotating seat 62. Therefore, after the high-pressure water flows into the pressurized atomizing nozzle 7, the clean water is atomized by the atomization of the atomization angle, and the dust is suppressed by spraying to expand the working area. At the same time, due to the existence of the extension pipeline 6, the high-pressure atomizing nozzle can be closer to the working position of the hole digging, providing a more accurate atomization dust suppression effect.

[0030] Furthermore, a spherical head 63 is provided at the end of the extension pipe 6, and the rotating seat 62 is a columnar structure plate and is provided with a spherical groove that transitions with the spherical head 63. The spraying angle of the high-pressure atomizing nozzle can be changed by rotating the high-pressure atomizing nozzle, so that the dust reduction range can be controlled more accurately.

[0031] The pump housing 3 is a disc-shaped plate integrally formed on one side of the connecting seat 2. The pump housing 3 is provided with a water inlet and a water outlet in the tangential direction to communicate with the inner cavity of the connecting seat 2. The pump housing 3 serves as the rotation space of the booster impeller 4. The booster impeller 4 is driven to rotate by the power assembly 5, so that the booster impeller 4 boosts the flowing water passing through. A manual valve 12 is provided on the water storage tank 1 to match the flow rate of the water in the water storage tank 1. The booster impeller 4 is composed of a ring sleeve mounted on the central support column in the pump housing 3 and a plurality of curved booster blades arranged on the ring sleeve.

[0032] A sealing disassembly cover is provided on the pump casing at one side corresponding to the boost impeller 4, through which the pump casing can be disassembled and the boost impeller 4 inside can be replaced.

[0033] Furthermore, the power assembly 5 includes an annular ferrule 51, which is composed of a pair of semi-annular ferrules 51 connected in tension. A rotating groove 52 is provided on the inner ring of the annular ferrule 51, and a follower wheel 53 is mounted on the inner ring of the annular ferrule 51. The follower wheel 53 is linked to the rotating shaft of the engineering machinery through a shaft key, and a power wheel 54 is provided on one side of the follower wheel 53 through a flywheel meshing, and a transmission rod 55 is provided on one side of the power wheel 54, and a supercharger gear sleeve 56 is provided on one end of the transmission rod 55 through a gear group linkage.

[0034] In the specific implementation process, the tension bolts on the annular sleeve 51 are removed, the annular sleeve 51 is used to embrace the shaft key position of the engineering machinery's rotating shaft, the follower wheel 53 is sleeved on the rotating shaft and the slot of the follower wheel 53 is clamped on the shaft key of the rotating shaft, the follower wheel 53 is limited by the rotating groove 52 of the annular sleeve 51, and then the annular sleeve 51 is closed and fixed by the tension bolts; when the rotating shaft of the engineering machinery rotates, the follower wheel 53 is synchronously driven by the shaft key, and the follower wheel 53 drives the power wheel 54 to rotate by flywheel meshing, so that the power wheel 54 drives the transmission rod 55 to rotate, so that the transmission rod 55 drives the booster gear sleeve 56 to rotate, and the booster gear sleeve 56 drives the central axis of the booster impeller 4 to rotate, and after multi-stage transmission, the power transmission of the engineering machinery drives the booster impeller 4 to rotate.

[0035] Furthermore, the central axis of the boost impeller 4 is connected to the boost gear sleeve 56 through a detachable connector 8. Specifically, the detachable connector 8 includes a protective housing 81 extending from one side of the annular sleeve 51 and wrapping the power wheel 54, the transmission rod 55, and the boost gear sleeve 56. The center of the boost gear sleeve 56 is provided with a hexagonal shaft hole 82, and one side of the central axis of the boost impeller 4 is a hexagonal shaft end 83, which is inserted into the hexagonal shaft hole 82, and a limiting bolt 84 is threadedly connected on the hexagonal shaft end 83 to fit the outer side of the hexagonal shaft hole 82.

[0036] In the specific implementation process, the protective shell 81 protects the power wheel 54, the transmission rod 55, and the booster gear sleeve 56, while providing a rotation space for the booster gear sleeve 56. The hexagonal shaft hole 82 at the center of the booster gear sleeve 56 is matched with the hexagonal shaft end 83 of the center axis of the booster impeller 4, so as to achieve the purpose of driving the booster impeller 4 to rotate through the booster gear sleeve 56.

[0037] Furthermore, a connecting clamp 9 is provided independently of the water tank 1, and the number of the connecting clamps 9 is at least two. One end of the connecting clamp 9 is a hoop structure sleeved on the water tank 1, and the other end of the connecting clamp 9 is provided with a restraining belt or an annular clamp connected to the outer casing of the engineering machinery.

[0038] During the specific implementation process, the water tank 1 is fixed by the connecting clamp 9. On the one hand, the connecting clamp 9 adopts a hoop structure to hold the outer wall of the water tank 1. On the other hand, it is connected to the outer shell of the engineering machinery through a ring clamp or a restraining belt to fix the position of the water tank 1.

[0039] From the above, it can be generally known that the portable spray dust removal device used at the bored pile construction site adopts a water storage tank 1 with a portable structural design as a dust reduction water storage container, which can follow the construction machinery down into the pipe pile, and then pump out water through the booster pump-out structure linked to the rotating shaft of the construction machinery, so that the water forms a spray through the booster atomizing nozzle 7, and accurately sprays and dusts the excavation construction position. Its small size can be used in conjunction with construction machinery without the need to modify the construction machinery, and has the outstanding characteristics of accurate and timely spray dust removal, convenient operation and compact structure.
