Abstract
Description
Technical Field
[0001] The invention relates to the field of mechanical cleaning, and more particularly to a concrete tank truck cleaning machine. Background Art
[0002] my country is a country with large infrastructure, and infrastructure requires a large amount of concrete, which needs to be transported by concrete tankers. In the process of transporting concrete, some concrete will remain on the tank body, and the stuck concrete will continue to stick to the tank after solidification, which will accumulate a lot over time. The stuck concrete not only reduces the number of cubic meters of concrete pulled each time, but also increases the weight of the concrete tanker and increases fuel consumption, causing economic losses, and even causing the tank to suffocate because there is no time to release the concrete.
[0003] At present, when cleaning concrete in concrete tank trucks, it is generally done manually using pneumatic picks. Pneumatic picks are loud and vibrate violently, which is harmful to the human body. At the same time, manual cleaning is slow and costly.
[0004] Therefore, it is very necessary to design a concrete tank truck cleaning machine which has fast washing speed, saves manpower and cleans well. Summary of the invention
[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to propose a cleaning machine that can clean concrete tank trucks. The high-pressure water is pressurized by a high-pressure water pump and then transported to a rotating nozzle through a high-pressure pipeline. The high-pressure water is sprayed from the nozzle and splashes onto the concrete on the inner wall of the concrete tank truck, thereby cutting and breaking the concrete and separating it from the cylinder of the concrete tank truck. After the cleaning is completed, the concrete tank truck is operated to remove the broken concrete to complete the cleaning work.
[0006] To achieve the above object, the present invention provides the following technical solutions:

DETAILED DESCRIPTION
[0023] The present invention is described in detail below with reference to the accompanying drawings.
[0024] Embodiment: A concrete tank truck cleaning machine relates to a cleaning machine capable of cleaning a concrete tank truck and capable of cleaning the concrete on the inner wall of a concrete tank truck.
[0025] like Figure 1 , Figure 2 and Figure 3As shown, it includes a workbench 1 and a cleaning device arranged on the workbench 1 and used for cleaning the inner wall of a concrete tanker 2. The cleaning device includes a frame 3 fixed on the workbench 1, a displacement adjustment mechanism installed on the frame 3, a telescopic arm 4 driven to move by the displacement adjustment mechanism, and a spray assembly installed on the telescopic arm 4. The displacement body of the telescopic arm 4 extends from the feed port of the concrete tanker 2 to the interior thereof; the side walls of the fixed body of the telescopic arm 4 are hinged on the displacement adjustment mechanism, and a first hydraulic cylinder 5 is connected between the displacement adjustment mechanism and the rear end of the telescopic arm 4; A high-pressure hose reel 6 is rotatably supported at the rear end by a tripod, and a water inlet 7 is arranged at the central position of the outer side plate of the turntable of the high-pressure hose reel 6, and the outer end of the water inlet 7 is connected to a swivel joint, and the swivel joint is connected to the high-pressure water pump in the water tank through a high-pressure pipe 1, and the inner end of the water inlet 7 is connected to a high-pressure pipe 2 8, which is spirally wound around the turntable of the high-pressure hose reel 6, and the water outlet end thereof passes through the bottom end of the fixed body of the telescopic arm 4 and extends to the inside of the telescopic arm 4, and a rotating nozzle 9 is arranged at the end of the moving body at the front end of the telescopic arm 4, and the water inlet 7 of the rotating nozzle 9 is connected to the water outlet end of the high-pressure pipe 2 8.
[0026] Operation process: adjust the height of the workbench 1 to be consistent with the height of the feed port of the concrete tanker, operate the first hydraulic cylinder 5 to adjust the telescopic arm 4 to a suitable angle, and adjust the displacement adjustment mechanism to adjust the telescopic arm 4 to a suitable position to facilitate the telescopic arm 4 to freely enter and exit the concrete tanker 2, start the high-pressure water pump to pass water through the high-pressure pipe. The high-pressure pipe will become very hard after passing water, and a general hose reel cannot be used. Therefore, a high-pressure hose reel 6 must be selected. When the telescopic arm 4 is started to make it begin to extend and retract, operate the hose reel to release or retract the pipe. Because a swivel joint is provided at the water inlet 7, the turntable of the high-pressure hose reel 6 and the high-pressure pipe connected to the swivel joint perform relative rotational displacement during the process of releasing and retracting the pipe, which can effectively avoid the entanglement of the high-pressure pipe. The rotating nozzle 9 can evenly spray high-pressure water on the inner wall of the concrete tanker, thereby cutting and breaking the concrete and separating it from the cylinder of the concrete tanker. After cleaning, operate the concrete tanker to remove the broken concrete to complete the cleaning work.
