Description

Technical Field

[0001] This utility model relates to the technical field of car washing devices, specifically to a car washing machine for a concrete mixing plant. Background Technology

[0002] In recent years, with the rapid development of society, a large number of concrete mixing plants have been built. Ready-mixed concrete is generally transported to designated construction sites by concrete mixer trucks. During the loading and unloading process, the vehicles often become contaminated. To ensure the vehicles' appearance and the cleanliness of the surrounding environment, timely cleaning is necessary. Currently, most cleaning is still done manually, requiring dedicated personnel to operate handheld water guns. This is not only labor-intensive but also time-consuming and inefficient. Although some mixing plants have installed automatic wheel and vehicle washing machines, the cleaning effect is unsatisfactory. Wheel washing machines can only clean the tires and chassis, not the body and roof. While vehicle washing machines can clean the entire exterior of the vehicle, the complex structure and irregular shape of the rear of the mixer truck often result in poor cleaning, requiring secondary manual cleaning.

The water outlet direction of the second nozzle 203 is downward, and the water outlet direction of the third nozzle 204 is tilted downward along the travel direction, which is from the first end 110 to the second end 120.

[0030] In use, vehicle 800 enters gantry 100 from the first end 110 and moves to the second end 120, and exits gantry 100 from the second end 120. During the process, it stops or moves depending on the cleanliness of vehicle 800. The first nozzle 201 is used to clean the tires of vehicle 800, and the spray pipe 202 is used to clean the body of vehicle 800. The body of vehicle 800 is cleaned from three directions, which can clean the body and tires of vehicle 800. Preferably, the outlet of spray pipe 202 is equipped with a nozzle to increase the cleaning effect. The second nozzle 203 is used to clean the inside and outside of the receiving hopper. The water outlet of the third nozzle 204 is inclined downward and the inclination direction is along the driving direction. It is used to clean the outside of the receiving hopper and the platform, guardrail, etc. at the rear of vehicle 800. It can clean vehicle 800 from all directions, with high cleaning efficiency and good cleaning effect.

[0031] In some embodiments, at least one second nozzle 203 is located at the first end 110, see [reference] Figure 2 , 3 5, 6, The bottom of the top frame 103 is equipped with a second nozzle 203 at the first end 110. During the cleaning process, the receiving hopper is specially cleaned before entering the gantry frame 100 to ensure the cleaning effect.

[0032] In some embodiments, at least one third nozzle 204 is located outside the first end 110, see [reference] Figure 1-4 An extension frame 108 is provided on the outside of the first end 110 of the top frame 103. A third nozzle 204 is provided at the bottom of the extension frame 108 away from the top frame 103. At this time, the water outlet direction of the third nozzle 204 is tilted inward. Special cleaning is carried out on the platform, guardrail, etc. outside the receiving hopper and at the rear of the vehicle 800 before entering the gantry frame 100 to ensure the cleaning effect.

[0033] In some embodiments, at least two first nozzles 201 and spray pipes 202 are located in the middle of the gantry 100 along the longitudinal direction. At least two first nozzles 201 are close to the second end 120, and spray pipes 202 are close to the first end 110. Before the vehicle 800 is cleaned, the tires are pre-cleaned to ensure the tire cleaning effect.

[0034] Preferably, see Figure 1 The water supply unit 300 includes a water tank 301, a high-pressure water pump 302, a high-pressure pipeline 303, and a solenoid valve assembly. The water tank 301 is placed outside the main body of the car wash machine. The size, shape, and position of the water tank 301 are designed and arranged according to actual needs. The high-pressure water pump 302 draws water from the water tank 301 through the high-pressure pipeline 303 and supplies high-pressure water flow to the spray assembly through the high-pressure pipeline 303. The solenoid valve assembly controls the on / off of the high-pressure water flow and is controlled by the control box 400. The solenoid valve assembly includes a first solenoid valve 304, a second solenoid valve 305, a third solenoid valve 306, and a fourth solenoid valve 307. The first solenoid valve 304 is used to control the on / off of the high-pressure water flow in the first nozzle 201, the second solenoid valve 305 is used to control the on / off of the high-pressure water flow in the spray pipe 202, the third solenoid valve 306 is used to control the on / off of the high-pressure water flow in the second nozzle 203, and the fourth solenoid valve 307 is used to control the on / off of the high-pressure water flow in the third nozzle 204.

[0035] See Figure 3 , 4 In some embodiments, the car wash machine body also includes at least one sensor 600, and the control box is also electrically connected to at least one sensor 600. At least one sensor 600 is set on the gantry 100 and at least one sensor 600 is located at the first end 110. Before or when the vehicle 800 enters the gantry 100, the sensor 600 is used to sense the vehicle 800. When the sensor 600 senses the vehicle 800, it sends a start signal to the control box. The control box controls the high-pressure water pump 302 to start and controls the solenoid valve group to open or close as needed to achieve vehicle 800 cleaning. Preferably, the number of sensors 600 is two, with one sensor 600 set on each of the first uprights 101.

[0036] See Figure 2 , 4 In some embodiments, the main body of the car wash machine also includes at least one indicator light 700, which is used to remind the driver to drive or stop the vehicle 800. The control box 400 is also electrically connected to at least one indicator light 700, and at least one indicator light 700 is set on the gantry 100. When the vehicle 800 moves to the designated position, the indicator light 700 lights up to remind the driver to stop so that the vehicle 800 can be cleaned locally, such as the hopper, the rear of the vehicle, and other parts with more dirt. Preferably, there are two indicator lights 700, with one indicator light 700 set on each of the second uprights 102.

[0037] Preferably, at least one indicator light 700 is located at the second end 120, which is the end where the vehicle leaves. During the cleaning process, it is located in front of the driver for most of the time, which is convenient for reminding the driver and for the driver to observe.

[0038] In operation, vehicle 800 slowly moves forward from end 110 towards the main body of the car wash machine. When sensor 600 detects vehicle 800, control box 400 starts high-pressure water pump 302 and simultaneously opens first solenoid valve 304 and second solenoid valve 305, causing water to flow from first nozzle 201 and spray pipe 202. As the vehicle moves forward, the front of vehicle 800 and front tires are first cleaned through spray pipe 202, and then the front tires are cleaned again through the first nozzle. When the front of vehicle 800 leaves the sensing range of sensor 600, control box 400 illuminates indicator light 700. The driver stops the vehicle based on the indicator light and controls third solenoid valve 306 to open, causing water to flow from second nozzle 203. At this time, to conserve water, the flow can be controlled... The first solenoid valve 304 and the second solenoid valve 305 are closed, and the second nozzle 203 performs a specialized cleaning of the inside and outside of the vehicle's receiving hopper. After a first preset cleaning time, the control box 400 controls the third solenoid valve 306 to close and the fourth solenoid valve 307 to open, causing the third nozzle 204 to spray water to clean the outside of the receiving hopper and the platform and guardrails at the rear of the vehicle. After a second preset cleaning time, the control box 400 controls the fourth solenoid valve 307 to close and controls the first solenoid valve 304 and the second solenoid valve 305 to open again. The control indicator light 700 of the control box 400 illuminates to remind the driver to continue driving. The spray pipe 202 performs a second cleaning of the inside and outside of the receiving hopper, as well as the platform and guardrails at the rear of the vehicle, and the first nozzle 201 cleans the remaining tires. When the rear of the vehicle 800 leaves the sensing range of the sensor 600, the car wash machine stops operating after a third preset time. The first, second, and third preset durations can be modified or preset as needed to meet the cleaning requirements of different vehicles.

[0039] In some embodiments, the car wash machine body also includes a base 500, with a gantry frame 100 fixed above the base 500 to ensure the service life of the car wash machine body. A water guide channel 502 is formed on the upper surface of the base 500. (See also...) Figure 2 , 3 The base 500 includes a base body 501, and a water guide channel 502 is opened on the top surface of the base body 501 to facilitate the collection and diversion of sewage. Four gantry supports 503 are provided on the base body 501, two of which are equipped with a first upright 101 and the other two are equipped with a second upright 102.

[0040] Furthermore, a water-blocking strip 504 is provided between the bottoms of the gantry supports 503 on the same horizontal side of the gantry frame to prevent excessive water accumulation on the base 500 from overflowing before the water guide channel 502 has time to guide the water.

[0041] In some embodiments, upright plates 900 are respectively provided on both sides of the gantry frame 100 to prevent sewage from splashing out during the cleaning process. See [reference needed] Figure 5 , 6 The upright plate 900 is positioned between the first horizontal bar 104 and the second horizontal bar 105 on the same horizontal side.

[0042] In some embodiments, the first nozzle 201, the second nozzle 203, and the third nozzle 204 are rotating nozzles to improve the cleaning effect.
