DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1In this embodiment, a small dust-proof tool for a construction site includes a base plate 1, a mounting frame 2 is fixed in the middle of the upper surface of the base plate 1, a hollow plate 3 is provided on the upper side of the mounting frame 2, a plurality of nozzles 4 are connected to the outer surface of the hollow plate 3, an adjusting mechanism 5 for adjusting the height of the nozzle 4 is provided on the upper surface of the base plate 1, a water tank 6 is fixed on the upper surface of the base plate 1 and located at the rear side of the mounting frame 2, and a filtering mechanism 7 for filtering impurities in water is provided at the left end of the upper surface of the water tank 6.

[0023] Among them, universal wheels are rotatably installed on the left and right ends of the lower surface of the bottom plate 1, and a handle is fixed on the upper surface of the bottom plate 1 and located on the rear side of the water tank 6. The outer surface of the handle is fixed with an anti-slip cover, which is a rubber cover.

[0024] In this embodiment, multiple nozzles 4 are evenly distributed on the outer surface of the hollow plate 3, a water pump is fixed to the right end of the upper surface of the water tank 6, the output end of the water pump is fixed to the upper surface of the hollow plate 3 through a water pipe and connected with its inner cavity, the input end of the water pump is connected with the inner cavity of the water tank 6 through a water pipe, and the cross-sectional shape of the mounting frame 2 is an inverted U shape.

[0025] It can be understood that when the water pump is started, the input end of the water pump can pump water in the water tank 6 to the output end, and finally flow into the hollow plate 3 and be sprayed out from the nozzle 4, which can reduce dust at the construction site. The water pipe connected to the output end of the water pump is a water pipe made of retractable material.

[0026] See also Figure 2 In order to reduce labor intensity, the adjustment mechanism 5 in this embodiment includes a fixing groove 501 opened on the upper surface of the bottom plate 1, and a motor 502 is fixed in the inner cavity of the fixing groove 501. The upper surface of the bottom plate 1 and the inner cavity of the mounting frame 2 are rotatably connected to two fixing rods 503 through bearings. The two fixing rods 503 are connected by belt transmission. The output shaft of the motor 502 passes through the bottom plate 1 and extends to the upper side of the bottom plate 1 and is fixed to the left end fixing rod 503. The inner cavity of the fixing rod 503 is threadedly connected with a screw. The threaded rod 504 starts the motor 502, and the output shaft of the motor 502 rotates to drive the left end fixed rod 503 to rotate. The rotation of the left end fixed rod 503 can drive the right end fixed rod 503 to rotate through a belt. The rotation of the two fixed rods 503 can make the threaded rod 504 threadedly connected to its inner cavity move upward. Through holes 505 are provided at both ends of the upper surface of the mounting frame 2. The upper surface of the threaded rod 504 passes through the through hole 505 and extends to the upper side of the through hole 505 and is fixed with a support frame 506.

[0027] Among them, the upper surface of the support frame 506 is fixed to the lower surface of the hollow plate 3, and the movement of the two threaded rods 504 can make the support frame 506 move upward, thereby increasing the height of the hollow plate 3 and the nozzle 4. A connecting ring is fixed on the outer surface of the threaded rod 504, and limiting rods are fixed on the opposite sides of the two connecting rings. Limiting strips are fixed on the top of the opposite sides of the left and right side walls of the inner cavity of the mounting frame 2, and the limiting rod makes linear up and down motion in the inner cavity of the limiting strip. When the fixed rod 503 rotates, the limiting ring and limiting rod fixed on the outer surface of the threaded rod 504 can limit the movement of the threaded rod 504, so that it can only move in a straight line.

[0028] See also Figure 3-4 In order to avoid clogging the nozzle 4, the filtering mechanism 7 in this embodiment includes a water inlet 701 connected to the left end of the upper surface of the water tank 6. The inner cavity of the water inlet 701 is provided with a filter screen plate 702. The aqueous solution entering the water tank 6 is filtered to avoid clogging the nozzle 4. The aqueous solution can be filtered by the filter screen plate 702. The left and right sides of the water inlet 701 are provided with mounting plates 703. The filter screen plate 702 needs to be replaced after being used for a period of time. At this time, the two mounting plates 703 are pulled to move back to back. A telescopic rod 704 and a spring 705 are fixed at the bottom between the mounting plate 703 and the opposite side of the water inlet 701. The spring 705 is movably sleeved on the outer surface of the telescopic rod 704, and an insert block 706 is fixed at the top between the mounting plate 703 and the opposite side of the water inlet 701.

[0029] There are slots on both sides of the filter screen plate 702. One end of the plug block 706 away from the mounting plate 703 passes through the water inlet 701 and extends to the inner cavity of the slot. The size of the plug block 706 matches the size of the inner cavity of the slot.

[0030] It can be understood that the movement of the mounting plate 703 drives the telescopic rod 704 and the spring 705 to extend, and drives the plug block 706 to move until the plug block 706 moves out of the slot, thereby removing the restrictions on the left and right ends of the filter screen plate 702, and then the filter screen plate 702 can be pulled out and replaced.

[0031] The working principle of the above embodiment is:

[0032] (1) When in use, it is first necessary to adjust the nozzle 4 to a suitable height, start the motor 502, and the output shaft of the motor 502 rotates to drive the left end fixing rod 503 to rotate. The rotation of the left end fixing rod 503 can drive the right end fixing rod 503 to rotate through the belt. The rotation of the two fixing rods 503 can cause the threaded rod 504 threadedly connected to its inner cavity to move upward. When the fixing rod 503 rotates, the limit ring and limit rod fixed on the outer surface of the threaded rod 504 can limit the movement of the threaded rod 504 so that it can only move in a straight line. The movement of the threaded rod 504 drives the limit rod to move upward in the inner cavity of the limit bar. The movement of the two threaded rods 504 can cause the support frame 506 to move upward, thereby increasing the height of the hollow plate 3 and the nozzle 4. Then start the water pump. The input end of the water pump can pump water from the water tank 6 to the output end, and finally flow into the hollow plate 3 and be sprayed out from the nozzle 4, which can reduce dust on the construction site.

[0033] (2) In order to filter the aqueous solution entering the water tank 6 and avoid clogging the nozzle 4, the aqueous solution can be filtered through the filter screen 702. After the filter screen 702 has been used for a period of time, it needs to be replaced. At this time, the two mounting plates 703 are pulled to move in opposite directions. The movement of the mounting plates 703 drives the telescopic rod 704 and the spring 705 to extend, and drives the plug block 706 to move until the plug block 706 moves out of the slot. The restrictions on the left and right ends of the filter screen 702 can be released, and the filter screen 702 can be pulled out and replaced.
