Description

Technical Field

[0001] The utility model relates to the technical field of concrete transportation equipment, in particular to a concrete tank truck feed hopper cleaning device. Background Art

[0002] Concrete is a building material commonly used in construction projects. After being mixed in a mixer, the concrete in the mixer is transported to the construction site by a tank truck. Due to the stickiness of concrete, part of the concrete will usually adhere to the inner wall of the tank truck's feed hopper. Over time, the inner cavity of the tank truck's feed hopper will be blocked, so the concrete tank truck's feed hopper needs to be cleaned regularly.

[0003] For example, Chinese patent CN218531969U relates to a concrete tank truck feed hopper cleaning device, which relates to the technical field of concrete transportation equipment. It includes a sleeve, a flushing assembly for flushing the inner wall of the tank truck feed hopper, a cleaning assembly for cleaning the inner wall of the tank truck feed hopper, and a fixing assembly for fixing the position of the sleeve and the tank truck feed hopper; the sleeve is coaxially sleeved on the tank truck feed hopper; the cleaning assembly includes a rotating tube, a frustum body coaxially fixed to one end of the rotating tube, and a plurality of steel bristles arranged on the side wall of the frustum body; the rotating tube passes through the top wall of the sleeve, the rotating tube is coaxially connected to the top wall of the sleeve for rotation, the frustum body is located in the inner cavity of the tank truck feed hopper, and the plurality of steel bristles are in contact with the inner wall of the tank truck feed hopper; the flushing assembly and the fixing assembly are arranged on the sleeve. This application has the effect of facilitating the cleaning of the tank truck feed hopper.

[0004] The above patent still has certain defects. The viscosity of the concrete remaining on the inner wall of the feed hopper of the concrete tanker increases due to the decrease in temperature. It is difficult to wash away all the concrete by simple flushing. Some concrete condenses on the inner wall of the feed hopper and requires a long time of flushing to be completely flushed. It is difficult to clean the sticky concrete by brushing with a steel brush, and some steel brushes will be stuck to the concrete, which will cause the cleaning of the residual concrete in the feed hopper of the concrete tanker not only time-consuming and labor-intensive, but also waste a lot of water resources, and may not necessarily clean the concrete thoroughly.

[0018] By adopting this technical solution, it is avoided that the feed hopper body is deflected by the impact of water flow during the flushing process, which makes it impossible to flush the feed hopper body clean.

[0020] By adopting this technical solution, the electric push rod can easily drive the clamping plate in the sleeve to move, while avoiding direct collision between the positioning block and the feed hopper body.

[0021] Furthermore, the cross-section of the clamping plates is arc-shaped, and buffer pads are fixed on opposite sides of the two clamping plates.

At the same time, the positioning is convenient, avoiding the complexity of manual positioning and improving the cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1 In this embodiment, a concrete tank truck feed hopper cleaning device includes a feed hopper body 5 provided on the concrete tank truck, a sleeve 4 is slidably connected to the outer side of the feed hopper body 5, and positioning mechanisms 6 for fixing the feed hopper body 5 are provided on the left and right sides of the sleeve 4. A water tank 2 is fixed to the upper surface of the sleeve 4, and the lower surface of the water tank 2 is connected to at least two nozzles 3 located inside the sleeve 4. A water supply mechanism 1 for improving cleaning efficiency is provided on the left side of the water tank 2. The electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology will not be repeated in this text. Connect the industrial power interface to power on the device, and the PLC system controls the entire device to operate as expected.

[0032] See also Figure 2In order to reduce the viscosity of concrete during cleaning, the water supply mechanism 1 in this embodiment includes a water supply pipe 107 connected to the left side of the water tank 2, the end of the water supply pipe 107 away from the water tank 2 is connected to a water pump 108, the lower surface of the water pump 108 is connected to a water pumping pipe 109, the end of the water pumping pipe 109 away from the water pump 108 is connected to the water supply tank 105, and at least two heating pipes 110 are fixed to the bottom wall of the inner cavity of the water supply tank 105. A temperature sensor 104 is fixed to the top wall of the inner cavity of the water supply tank 105. The model of the temperature sensor 104 is TR / 02010. A drive box 102 is fixed to the left side of the water supply tank 105, and a motor 103 is fixed to the left side wall of the inner cavity of the drive box 102. The outer side of the output shaft of the motor 103 is rotatably connected to the rotating shaft 106, and the outer side of the rotating shaft 106 is fixed to at least two stirring rods 101.

[0033] When the water temperature reaches the set value, the water pump 108 is started. The water pump 108 draws the water out of the water supply tank 105 through the pumping pipe 109 and transports it to the water storage tank 2 through the water supply pipe 107. The water storage tank 2 sprays hot water to the feed hopper body 5 through the nozzle 3 to clean it. The high-temperature water flow hits the concrete to reduce its viscosity. At the same time, the mixed high-efficiency water reducer penetrates into the concrete to reduce its viscosity again. After the viscosity of the concrete is reduced, the fluidity is greatly improved, so it can be easily washed away by the water flow.

[0034] In this embodiment, a water injection hole is provided on the upper surface of the water supply box 105, and a box cover is connected to the inner thread of the water injection hole, which is convenient for the staff to open the water supply box 105 to replenish water and add high-efficiency water reducer therein. The left and right side walls of the inner cavity of the water supply box 105 are provided with mounting grooves, and a sealed bearing is fixed inside the mounting groove. The rotating shaft 106 is fixed inside the sealed bearing, so that when the rotating shaft 106 rotates, the water supply box 105 will not rotate with the rotating shaft 106. At the same time, the sealed bearing prevents the water in the water supply box 105 from leaking out. The water pump 108 is fixed on the right side of the water supply tank 105. A water outlet is provided on the right side of the water supply tank 105, located on the lower side of the water pump 108, to prevent the water pump 108 from moving around and pulling the pipe at will, and to facilitate the connection to the suction pipe 109 through the water outlet. There are at least two stirring rods 101 evenly distributed on the outside of the rotating shaft 106. The evenly distributed stirring rods 101 make the water flow stir evenly, thereby evenly dissolving the medicine in the water in different areas. There are at least two heating tubes 110 evenly distributed on the bottom wall of the inner cavity of the water supply tank 105.

[0035] It should be noted that the water supply mechanism 1 stirs the water in the water supply tank 105 through the stirring rod 101, the drive box 102 and the motor 103, so that the high-efficiency water reducer put into the water supply tank 105 is quickly dissolved into the water. At the same time, the heating pipe 110 is used to increase the water temperature and accelerate the dissolution rate of the high-efficiency water reducer again, so that the high-efficiency water reducer can effectively exert its efficacy when it is sprayed out with the water flow.

[0036] See also Figure 3 In order to facilitate the fixation of the feed hopper body 5, the positioning mechanism 6 in this embodiment includes two connecting boxes 603 fixed on the left and right sides of the sleeve 4 respectively, and electric push rods 602 are fixed on the inner cavity walls on the opposite sides of the two connecting boxes 603. The outer sides of the output shafts of the two electric push rods 602 are fixed with clamping plates 601, and there is a positioning block 604 inside the sleeve 4.

[0037] In this embodiment, through holes for the electric push rod 602 to pass through are provided on the left and right sides of the sleeve 4, and the electric push rod 602 is slidably connected to the sleeve 4 through the through holes. A rubber pad is fixed to the lower surface of the positioning block 604, and the rubber pad prevents the positioning block 604 from directly colliding with the feed hopper body 5. The cross-section of the clamping plate 601 is arc-shaped, and the arc-shaped clamping plate 601 is convenient for clamping and fixing the feed hopper body 5. Buffer pads are fixed on the opposite sides of the two clamping plates 601. The control method of this application is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and this application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.

[0038] It should be noted that the positioning mechanism 6 fixes the feed hopper body inside the sleeve 4 through the cooperation of the clamping plate 601, the electric push rod 602, the connecting box 603 and the positioning block 604, so as to avoid the feed hopper body 5 being deflected by the impact of water flow during the flushing process, resulting in an inability to flush thoroughly. At the same time, the positioning is convenient, avoiding the complexity of manual positioning and improving the cleaning efficiency.

[0039] The working principle of the above embodiment is:

[0040] (1) When cleaning the feed hopper body 5, fill the water supply tank 105 with water and add high-efficiency water reducer. Then start the heating pipe 110 and the motor 103. The motor 103 drives the rotating shaft 106 to rotate through the output shaft. While the rotating shaft 106 rotates, it drives the stirring rod 101 to stir the water in the water supply tank 105, so that the high-efficiency water reducer dissolved in the water is quickly dissolved. At the same time, the dissolution efficiency of the high-efficiency water reducer is further increased through the cooperation of the heating pipe 110. The temperature sensor 104 detects the water temperature in real time. When the water temperature reaches the set value, the water pump 108 is started. The water pump 108 pumps the water in the water supply tank 105 through the pumping pipe 109 and transports it to the water storage tank 2 through the water supply pipe 107. Inside, the water storage tank 2 sprays hot water to the feed hopper body 5 through the nozzle 3 and cleans it. The high-temperature water flow hits the concrete to reduce its viscosity. At the same time, the mixed high-efficiency water reducer penetrates into the concrete to reduce its viscosity again. After the viscosity of the concrete is reduced, the fluidity is greatly improved so that it can be easily washed away by the water flow. The water supply mechanism 1 stirs the water in the water supply tank 105 through the stirring rod 101, the drive box 102 and the motor 103, so that the high-efficiency water reducer put into the water supply tank 105 is quickly dissolved in the water. At the same time, the heating pipe 110 is used to increase the water temperature and accelerate the dissolution rate of the high-efficiency water reducer again, so that the high-efficiency water reducer can effectively exert its efficacy when it is sprayed out with the water flow.

[0041] (2) When the feed hopper body 5 needs to be cleaned, the feed hopper body 5 is placed inside the sleeve 4, and the upper surface of the feed hopper body 5 is fitted with the positioning block 604. Then, the two electric push rods 602 are started at the same time. The two electric push rods 602 drive the two clamping plates 601 to approach the feed hopper body 5 through the output shaft. When the rubber pad on the clamping plate 601 is tightly fitted with the feed hopper body 5, the electric push rod 602 is closed to complete the fixation of the feed hopper body 5. The positioning mechanism 6 fixes the feed hopper body inside the sleeve 4 through the cooperation of the clamping plate 601, the electric push rod 602, the connecting box 603 and the positioning block 604, so as to avoid the feed hopper body 5 from being deflected by the impact of water flow during the flushing process, resulting in an inability to flush cleanly. At the same time, positioning is convenient, avoiding the complexity of manual positioning and improving cleaning efficiency.
