Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, and in particular to a slag-pushing mechanism for the gripper of a cleaning machine. Background Technology

[0002] In the field of wastewater treatment technology, bar screens are key pretreatment equipment for intercepting solid impurities (such as floating objects and suspended solids) in water, and their operating efficiency directly affects the stability of subsequent wastewater treatment processes. To prevent bar screens from being clogged by impurities, it is necessary to regularly remove impurities from the surface and crevices of the bar screen using a screen cleaning machine. Among these, claw-type screen cleaning machines have become one of the mainstream devices due to their strong gripping ability and wide adaptability.

[0003] In the working process of a claw-type screen cleaner, the claw-type stationary rake first pushes the impurities on the screen to the lower limit. These impurities will accumulate at the bottom of the stationary rake, and then the claws will close and grab the impurities and transfer them. However, during this process, some small impurities or fibrous impurities can easily get embedded in the teeth of the stationary rake. If they are not cleaned in time, they will gradually accumulate and cause the stationary rake teeth to become clogged. This not only reduces the grabbing efficiency of the claws, but may also increase the operating load of the screen cleaner due to the compaction of impurities, and may even cause the claws to jam when rising or falling.

[0004] In existing technologies, when cleaning the stationary rakes on a cleaning machine, the teeth are cleaned by the natural falling of the rakes due to weight and by manual cleaning, resulting in reduced cleaning efficiency. Although some cleaning equipment has emerged to clean the stationary rakes, most of the existing cleaning equipment is an integral flat structure or a comb structure with tooth spacing that does not match the stationary rake. This makes it impossible to accurately embed the equipment into the tooth gaps of the stationary rake, resulting in the inability to completely remove residual impurities from the tooth gaps. After long-term accumulation, manual cleaning is still required, increasing operation and maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide a slag pushing mechanism for the gripper of a cleaning machine, which can solve the above-mentioned technical problems.

[0006] This utility model provides a slag-pushing mechanism for the grippers of a cleaning machine, comprising:

[0007] The mounting bracket is installed on the frame of the cleaning machine;

[0008] The drive unit is mounted on the mounting bracket, and a movable plate is mounted on the drive unit;

[0009] The first support group and the second support group are arranged opposite to each other on the mounting frame; and the two ends of the movable plate are movably arranged on the first support group and the second support group.

[0010] The pusher is set on the moving plate, and several pusher teeth are provided on the pusher, and the pusher teeth are adapted to the tooth gaps on the stationary rake.

[0011] As a further technical solution, it also includes:

[0012] The sensor is mounted on the moving plate;

[0013] Several sensors are mounted on the mounting bracket.

[0014] Preferably, there are two sensors.

[0015] As a further technical solution, the driving device includes:

[0016] The drive unit is mounted on the mounting platform set on the mounting bracket;

[0017] The drive shaft is connected to the drive body at one end and rotatably mounted in a support on the mounting bracket at the other end.

[0018] Preferably, the driving element is a geared motor and the driving shaft is a lead screw.

[0019] As a further technical solution, a moving platform is provided on the moving plate. The moving platform is located directly below the moving plate and is fixed to the moving plate by bolts. The drive shaft passes through the moving platform.

[0020] As a further technical solution, the first support group includes:

[0021] The optical axis and the mounting brackets at both ends of the optical axis are mounted on the mounting frame.

[0022] As a further technical solution, a sliding sleeve is provided on the moving plate, and the sliding sleeve is fitted on the optical axis.

[0023] Preferably, the sliding sleeve is a linear bearing.

[0024] As a further technical solution, a gap is formed between adjacent push teeth, and the gap corresponds to the teeth on the stationary rake.

[0025] The technical solution of this utility model, by setting a driving device on the mounting frame, drives the moving plate, push frame, and push teeth to move, thereby achieving mechanized cleaning of impurities in the gaps between the teeth of the stationary rake. This eliminates the need for manual cleaning of the rake teeth gaps, solving the problem of low efficiency in manual cleaning. It can adapt to the continuous operation rhythm of the cleaning machine, significantly improving the overall cleaning efficiency. Furthermore, the push frame is equipped with several push teeth adapted to the gaps between the teeth of the stationary rake. These push teeth can precisely embed into the gaps of the rake teeth, and under the drive of the driving device, they can completely push out small impurities and fibrous impurities from the gaps, effectively preventing impurities from accumulating and clogging them. This solves problems such as the inability of the gripper rake to insert into the grid, gripper jamming during rise and fall, decreased gripping efficiency, and increased operating load on the cleaning machine caused by impurity accumulation. Moreover, this utility model's technical solution, through mechanized cleaning, can achieve the cleaning of impurities in the gaps between the teeth of the stationary rake, eliminating the need for subsequent manual cleaning, reducing manual maintenance, lowering labor and maintenance costs, and improving the economic efficiency of equipment operation.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figures 1 to 2 As shown, this utility model proposes a slag-pushing mechanism for the gripper of a sludge cleaning machine, comprising:

[0035] Mounting bracket 100 is mounted on the frame 800 of the cleaning machine; a drive unit is mounted on the mounting bracket 100, and a movable plate 300 is mounted on the drive unit; under the push of the drive unit, the movable plate 300 moves on the mounting bracket 100; specifically, a first support group and a second support group are arranged opposite to each other on the mounting bracket 100; and both ends of the movable plate 300 are movably mounted on the first support group and the second support group; when the drive unit moves the movable plate 300, the movable plate 300 moves on the first support group and the second support group, and moves through the first support group and the second support group. The support assembly restricts the movement trajectory of the moving plate 300 to ensure its stability during movement. The pusher 500 is mounted on the moving plate 300 and has several pusher teeth 600 that are adapted to the tooth gaps on the stationary rake. During the movement of the moving plate 300, the pusher 500 is driven to move simultaneously, and the pusher teeth 600 on the pusher 500 are inserted into the tooth gaps of the stationary rake to push away the impurities inside. After one cleaning operation is completed, the pusher teeth 600 are reset by the drive device to wait for the next cleaning operation.

[0036] It should be noted that the stationary rake has multiple teeth, and the teeth form gaps between them; while adjacent push teeth 600 form gaps, which correspond to the teeth on the stationary rake; during use, several push teeth 600 are inserted into the gaps on the stationary rake, and the teeth on the stationary rake are inserted between adjacent push teeth 600; in this way, there is no extra space between the gaps on the stationary rake and the adjacent push teeth 600; then the impurities attached to the stationary rake will be pushed off the stationary rake by several push teeth 600, improving the cleaning effect of impurities; in this utility model, the number of push teeth 600 and the number of teeth on the stationary rake are determined according to the actual situation, and this utility model will not explain further.

[0037] The technical solution of this utility model is to install a driving device on the mounting frame 100, which drives the moving plate 300, the push frame 500, and the push teeth 600 to move, thereby realizing the mechanized cleaning of impurities in the gaps between the teeth of the stationary rake. This eliminates the need for manual cleaning of the gaps between the teeth, solving the problem of low efficiency in manual cleaning. It can adapt to the continuous operation rhythm of the cleaning machine and significantly improve the overall cleaning efficiency. In addition, the push frame 500 is equipped with several push teeth 600 that are adapted to the gaps between the teeth of the stationary rake. The push teeth 600 can be precisely embedded in the gaps between the teeth of the stationary rake. Driven by the driving device, they can completely push out the small impurities and fibrous impurities in the gaps, effectively preventing impurities from accumulating and clogging in the gaps. This solves the problems caused by impurity accumulation, such as the grabber being unable to insert the stationary rake into the grid, the grabber getting stuck when rising and falling, the decrease in grabbing efficiency, and the increase in the operating load of the cleaning machine. Furthermore, the technical solution of this utility model can realize the cleaning of impurities in the gaps between the teeth of the stationary rake through mechanized cleaning, eliminating the need for subsequent manual cleaning, reducing manual operation and maintenance links, lowering labor costs and operation and maintenance management costs, and improving the economic efficiency of equipment operation.

[0038] like Figure 1 As shown, this utility model also includes a sensing plate 701 mounted on the moving plate 300; and several sensors 702 mounted on the mounting bracket 100. The position of the moving plate 300 is detected by the cooperation of the sensing plate 701 and the sensors 702, and the position of the pusher 600 is obtained by the moving distance of the moving plate 300. Preferably, there are two sensors 702. One sensor 702 is set at the initial position of the moving plate 300 (the position waiting to clean the static rake), and the other sensor 702 is set at the stop position of the moving plate 300 (the position after the pusher 600 is inserted into the tooth gap of the static rake). During use, the sensing plate 701 moves simultaneously with the moving plate 300 and contacts the two sensors 702 respectively. By contacting different sensors 702, the forward and reverse actions of the drive device are realized.

[0039] Specifically, the drive device pushes the moving plate 300 to move, and during the movement of the moving plate 300, it drives the sensing plate 701 to move, causing the sensing plate 701 to separate from the sensor 702 at the initial position. As the moving plate 300 continues to move, the pusher 600 will insert into the tooth gap on the stationary rake. At this time, the sensor 702 at the stop position senses the sensing plate 701 and sends a signal to stop the drive device and reverse its movement, causing the moving plate 300 to move in the opposite direction. When the sensor 702 at the initial position senses the sensing plate 701, it generates a signal to stop the drive device. Preferably, the sensor 702 is an inductive proximity switch.

[0040] It should be noted that sensor 702 is connected to the controller (microcontroller or PLC control board) on the cleaning machine. The controller on the cleaning machine obtains signals from the two sensors 702 respectively, and controls the drive device through the obtained signals; thus, it can control the action of the drive device more accurately and improve the overall operation continuity.

[0041] like Figure 1 As shown, the driving device includes a driving body 201 mounted on a mounting platform 101 on a mounting frame 100; one end of a driving shaft 202 is connected to the driving body 201, and the other end is rotatably mounted in a support seat 102 on the mounting frame 100; in use, the driving body 201 drives the driving shaft 202 to rotate, and the driving shaft 202 drives the moving plate 300 to move on the first support group and the second support group; in this utility model, preferably, the driving body 201 is a geared motor, and the driving shaft 202 is a lead screw;

[0042] In addition, a movable stage (not shown in the figure) is provided on the movable plate 300. The movable stage is located directly below the movable plate 300 and is fixed to the movable plate 300 by bolts. The drive shaft 202 passes through the movable stage. The movable stage is provided with an internal thread, and the internal thread is adapted to the thread on the drive shaft 202. When the drive body 201 drives the drive shaft 202 to rotate, the movable plate 300 is moved by the internal thread in the movable stage cooperating with the drive shaft 202.

[0043] In this invention, the first support group includes an optical shaft 411 and fixed seats 412 disposed at both ends of the optical shaft 411. The fixed seats 412 are disposed on the mounting frame 100. When the movable plate 300 moves, it can slide on the optical shaft 411. Specifically, the movable plate 300 is provided with a sliding sleeve 301, which is sleeved on the optical shaft 411. When the movable plate 300 moves under the push of the driving device, it drives the sliding sleeve 301 to slide on the optical shaft 411. The position of the movable plate 300 is limited by the cooperation between the sliding sleeve 301 and the optical shaft 411 to ensure the stability of the movable plate 300 during movement. Preferably, the sliding sleeve 301 is a linear bearing. In this invention, the second support group has the same structure as the first support group, but is disposed opposite to the first support group on the mounting frame 100. To save space, the second support group will not be further described in this invention.

[0044] like Figure 2 As shown, after each or several unloading operations, the claws on the cleaning machine can drive the pusher 600 to clean the stationary rake on the claws via the drive device. Under the control of the controller on the cleaning machine, the drive device drives the pusher 600 to perform forward (pusher 600 moves towards the stationary rake) or reverse (pusher 600 moves away from the stationary rake) movements. During the operation, the controller receives signals from the two sensors 702 and controls the start and stop of the drive device, and changes the movement direction of the pusher 600.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
