Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing stations, in particular to a novel automatic cleaning device for a concrete discharging hopper. Background Art

[0002] With the widespread use of commercial concrete, concrete mixing plants are becoming increasingly automated to improve production efficiency and reduce costs. Traditional commercial concrete mixing plants lack cleaning devices for the mixer hoppers (or have only simple, ineffective cleaning devices). Concrete adhesion requires manual cleaning after the plant is shut down, which is time-consuming and labor-intensive, and impacts production. This issue has become a significant issue affecting mixing plant production efficiency and urgently needs to be addressed.

[0003] Existing cleaning devices for concrete mixing plants can only clean a fixed area due to the fixed flushing pipes. This results in a large blind spot and poor cleaning effect. To improve the flushing effect, the only way is to increase the number of nozzles and the water pump flow rate, which increases the cost and makes it of little commercial value. Utility Model Content

[0004] In view of the above problems, the present utility model is proposed to provide a new automatic cleaning device for concrete discharge hopper that overcomes the above problems or at least partially solves the above problems. It can solve the problems of large cleaning blind spots and poor cleaning effects of the cleaning device used for the mixer discharge hopper, thereby improving the cleaning effect of the mixer discharge hopper.

[0005] Specifically, the utility model provides a novel automatic cleaning device for a concrete hopper, which is arranged at the outlet of a mixer hopper. The novel automatic cleaning device for a concrete hopper comprises:

[0006] A plurality of support frames, the plurality of support frames being evenly distributed circumferentially along the axis direction of the outlet of the discharge hopper, and the support frames being mounted on the inner wall of the discharge hopper;

[0007] Multiple cleaning components, each comprising a spray pipe; each spray pipe having a plurality of nozzles for spraying water evenly distributed along its length; each spray pipe being rotatably mounted on one of the support frames, and the spray pipe being perpendicular to the axis of the outlet of the hopper, so that when the spray pipe rotates, the nozzles are driven to rotate around the axis of the spray pipe;

[0008] a plurality of rotary drive assemblies, each of the rotary drive assemblies being mounted on one of the support frames and connected to one of the spray pipes to drive the spray pipe to rotate;

[0009] A water supply system is connected to the spray pipe and is used to provide a high-pressure water source into the spray pipe.

[0010] Optionally, the cleaning assembly further includes a check valve; the check valve is arranged on the nozzle.

[0011] Optionally, the support frame includes a first frame body and a second frame body; the first frame body and the second frame body are both fixedly mounted on the discharge hopper;

[0012] Both the first frame and the second frame are provided with mounting holes; bearings are provided in the two mounting holes; the two ends of the spray pipe are respectively inserted into the bearings of the first frame and the second frame; the rotation drive assembly is installed on the first frame and connected to the spray pipe.

[0013] Optionally, the rotation drive assembly includes a drive motor and a drive shaft; the drive motor is fixedly mounted on the first frame; one end of the drive shaft is connected to the spray pipe, and the other end is connected to the drive motor; the drive motor is a stepping motor, used to drive and adjust the rotation speed of the spray pipe.

[0014] Optionally, the water supply system includes a water storage tank, a water pump, a starter ball valve, a filter and a water supply pipe;

[0015] One end of the water supply pipe is connected to the water storage tank, and the other end is connected to one end of the spray pipe; the water pump, the starting ball valve and the filter are arranged between the water supply tank and the spray pipe, and are arranged on the water supply pipe in sequence.

[0016] Optionally, the cross-section of the outlet of the discharge hopper is rectangular; there are four support frames and four cleaning components; and the spray pipe is parallel to the inner wall of the discharge hopper.

[0017] The new automatic cleaning device for the concrete discharge hopper of the present invention has multiple support frames, multiple cleaning components, multiple rotary drive components and a water supply system, and the cleaning device is arranged at the outlet of the mixer discharge hopper. The arrangement of multiple spray pipes uniformly distributed circumferentially around the discharge hopper enables the nozzles of the spray pipes to clean the peripheral wall of the discharge hopper, thereby increasing the cleaning area of ​​the discharge hopper. The rotation of the spray pipe can drive the nozzle to rotate, thereby enabling high-pressure water to be sprayed out in a rotary manner. The high-pressure water sprayed out in a rotary manner can further wash the discharge hopper in all directions, thereby achieving the effect of cleaning without dead angles or blind spots. In other words, when the spray pipe rotates, it can drive the nozzle to rotate along the axis of the spray pipe, thereby changing the corresponding position of the nozzle, so that the area cleaned by the nozzle changes with the change of the spray pipe.

[0029] Figure 1 This is a schematic structural diagram of a new type of concrete hopper automatic cleaning device. Figure 1 As shown, and reference Figures 2 to 4The embodiment of the present invention provides a novel automatic cleaning device for a concrete discharge hopper. The cleaning device is arranged at the outlet of the mixer discharge hopper 100. The novel automatic cleaning device for the concrete discharge hopper 100 includes a plurality of support frames 200, a plurality of cleaning components 300, a plurality of rotary drive components 400, and a water supply system. The plurality of support frames 200 are evenly distributed circumferentially along the axis of the outlet of the discharge hopper 100, and the support frames 200 are mounted on the inner wall of the discharge hopper 100. The cleaning component 300 includes a spray pipe 310; the spray pipe 310 is evenly distributed along its length with a plurality of nozzles 320 for spraying water. Each spray pipe 310 is rotatably arranged on a support frame 200, and the spray pipe 310 is perpendicular to the axis of the outlet of the discharge hopper 100, so that when the spray pipe 310 rotates, the nozzle 320 is driven to rotate around the axis of the spray pipe 310. Each rotary drive assembly 400 is mounted on a support frame 200 and connected to a spray pipe 310 to drive the spray pipe 310 to rotate. A water supply system is connected to the spray pipe 310 to provide high-pressure water to the spray pipe 310.

[0030] Specifically, the support frame 200 is detachably configured, and further, the axis is the axis of the inscribed circle of the discharge hopper. Furthermore, the arrangement of multiple spray pipes 310 evenly distributed circumferentially around the discharge hopper 100 enables the nozzles 320 of the spray pipes 310 to clean the peripheral walls of the discharge hopper 100, thereby increasing the cleaning area of ​​the discharge hopper 100. Furthermore, the rotation of the spray pipes 310 drives the nozzles 320 to rotate, thereby enabling the high-pressure water to be sprayed in a rotating manner. The rotating high-pressure water can further wash the discharge hopper 100 in all directions, achieving a zero-dead-spot cleaning effect. In other words, when the spray pipes 310 rotate, the nozzles 320 can be driven to rotate along the axis of the spray pipes 310, thereby changing the corresponding position of the nozzles 320, so that the area cleaned by the nozzles 320 changes with the changes in the spray pipes 310. Furthermore, the number of nozzles 320 and the flow rate of the cleaning water are both low, thereby reducing overall costs.

[0031] During operation, the water supply system and rotary drive assembly 400 are activated. The water supply system pressurizes water and introduces it into the spray pipe 310. The high-pressure water enters the spray pipe 310 and is ejected from the nozzle 320, cleaning the discharge hopper 100. The rotary drive assembly 400 rotates the spray pipe 310, which in turn rotates the nozzle 320 of the spray pipe 310, achieving a comprehensive, all-around cleaning of the discharge hopper 100.

[0032] In some embodiments of the present invention, Figure 4As shown, the cleaning assembly 300 also includes a check valve 330, which is installed on the nozzle 320. Specifically, the check valve 330 is a one-way valve that only allows water to be sprayed outward along the nozzle 320. Furthermore, the check valve 330 prevents concrete from accumulating in the discharge hopper 100 and covering the spray pipe 310, causing concrete to flow back through the nozzle 320 and into the spray pipe 310, thereby clogging the nozzle 320. Therefore, the installation of the check valve 330 ensures the normal operation of the nozzle 320.

[0033] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the support frame 200 includes a first frame 210 and a second frame 220, both of which are fixedly mounted on the discharge hopper 100. Mounting holes are provided on both the first frame 210 and the second frame 220. Bearings 230 are disposed within each mounting hole, and the ends of the spray pipe 310 are respectively inserted into the bearings 230 of the first frame 210 and the second frame 220. The rotation drive assembly 400 is mounted on the first frame 210 and connected to the spray pipe 310.

[0034] Specifically, the provision of the bearing 230 can increase the flexibility of the spray pipe 310 during rotation. Furthermore, both ends of the spray pipe 310 are detachably inserted into the corresponding holes of the bearing 230, thereby facilitating the disassembly and replacement of the spray pipe 310.

[0035] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the rotation drive assembly 400 includes a drive motor 410 and a drive shaft 420. The drive motor 410 is fixedly mounted on the first frame 210. One end of the drive shaft 420 is connected to the spray pipe 310, and the other end is connected to the drive motor 410. The drive motor 410 is a stepper motor used to drive and adjust the rotation speed of the spray pipe 310.

[0036] Specifically, the cleaning device also includes a control module for controlling the rotational speed of the drive motor 410, thereby adjusting the rotational speed of the spray pipe 310 to ensure high-intensity spraying in key areas and reduce the occurrence of concrete adhesion. Furthermore, the drive shaft 420 is connected to the drive motor 410 via a coupling 430, and the drive motor 410 is connected to a reducer 440.

[0037] In some embodiments of the present invention, Figure 1 and Figure 4As shown, the water supply system includes a water tank 520, a water pump 530, a starter ball valve 540, a filter 550, and a water supply pipe 510. One end of the water supply pipe 510 is connected to the water tank 520, and the other end is connected to one end of the spray pipe 310. The water pump 530, the starter ball valve 540, and the filter are arranged between the water supply tank and the spray pipe 310, and are sequentially arranged on the water supply pipe 510.

[0038] Specifically, the water pump 530 is used to pressurize the water in the water supply pipe 510, the starter ball valve 540 is used to control the opening and closing of the water supply pipe 510, and the filter 550 is used to filter the water flowing through the water supply pipe 510, thereby preventing the spray head 320 from being clogged by impurities in the water. Furthermore, a hydraulic rotary joint 240 is provided on the second frame 220. One end of the hydraulic rotary joint 240 is connected to one end of the spray pipe 310, and the other end is connected to the other end of the water supply pipe 510. Furthermore, the water supply pipe 510 includes a main pipe and multiple branch pipes. The starter ball valve 540, filter 550, and water pump 530 are all provided on the main pipe, and each branch pipe is connected to a spray pipe 310.

[0039] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the outlet of the hopper 100 has a rectangular cross-section. There are four support frames 200 and four cleaning assemblies 300, each with spray pipes 310 running parallel to the inner wall of the hopper 100. Specifically, the four spray pipes 310 form a rectangular structure, corresponding to the four sides of the hopper 100. As each spray pipe 310 rotates, the water sprayed from the nozzle 320 cleans the corresponding sidewall 360 degrees without blind spots.

[0040] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
