Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, and more specifically to a rotary cleaning machine with toothed rake bending detection. Background Technology

[0002] Rotary trash rack cleaners use cleaning rakes to clean and remove debris from the trash rack bars, gaps between bars, and the water accumulated in front of the rack. By rotating the cleaning rakes around the rack, the entire trash rack surface is thoroughly cleaned from bottom to top, achieving the goals of unblocking the trash rack, improving water intake conditions, increasing water flow, and improving project efficiency. The rotary trash rack cleaner is a fixed, continuous trash rack cleaning device that combines trash racking and cleaning into one unit. It uses the trash rack as its base, on which a transmission device, traction chain device, and cleaning rakes are assembled.

[0003] Because the types of debris in rivers or reservoirs are diverse, debris can remain on the rake teeth, which can easily lead to poor cleaning effect and overload of the drive unit. When encountering bumps or knocks, the rake teeth can also bend, including two situations: bending of the rake handle and bending of the rake teeth. Both situations will cause the machine to operate poorly, reduce the cleaning effect, and aggravate the overload of the drive unit. Utility Model Content

A gap is left between adjacent baffles 5 and corresponds one-to-one with several rake teeth 9. During the operation of the rotary cleaning machine, the rake teeth 9 pass through the gaps. The rake teeth 9 that bend will hit the corresponding baffle 5 and bend. The rotation occurs; support plates 3 are provided on both sides below the top of the shell, and the spindle 7 is fixed between the two support plates 3; several rotating sleeves 6 are rotatably fitted on the outside of the spindle 7, and baffles 5 are fixedly installed on the outer surface of the rotating sleeves 6; the distance between the edge of the baffle 5 and the rake teeth 9 on both sides is 3-5 mm; a damping pad 11 is also provided between the spindle 7 and the rotating sleeves 6; the damping pad 11 is made of rubber; a return assembly is also rotatably provided on the spindle 7, the return assembly includes a return sleeve 4 rotatably fitted on the spindle 7, and a return rod 8 is fixedly provided on the return sleeve 4; the length of the return rod 8 is greater than the length of the rake rod 2; a handle 10 is provided at the end of the return rod 8.

[0023] The first embodiment of this utility model is as follows:

[0024] A rotary screen cleaner with toothed rake bending detection includes a rotary screen cleaner and a bending detection component installed on the top of the rotary screen cleaner. The rotary screen cleaner includes a screen body, cleaning rakes, and a transmission part. The screen body includes a head frame, a screen body, and a guide rail. The screen body is installed inside the head frame, and the guide rail is located between the screen body and the head frame. The head frame is constructed by welding H-beams, with two H-beams on both sides and connected in the middle by horizontal H-beams to form an overall frame. Then, several H-beams are arranged horizontally and welded to the guide rail to form a chain-driven frame, which is located inside the overall frame.

[0025] The housing 1 is formed by welding steel and installed on the upper part of the overall frame. The motor, reducer, main shaft and drive sprocket are installed inside the housing 1.

[0026] A driven sprocket is installed at the lower end of the overall frame, and a bottom auxiliary debris barrier is installed at the very bottom of the overall frame. The bottom auxiliary debris barrier includes a mounting frame. The front longitudinal section of the mounting frame has a structure with upward convex sides and a concave center. The convex parts connect to the overall frame, and the rake passes through the concave center. The lateral longitudinal section of the mounting frame has an L-shaped structure, and auxiliary debris barrier bars are installed at the bottom front end. The outermost end of the rake travels within the concave center during operation. The bottom auxiliary debris barrier does not affect the normal operation of the rotating rake. Driven by a motor, the rake moves upward, lifting and moving the debris upward. After flipping, the debris is thrown onto the conveyor belt. Then, the rake passes through a combing device to clean the debris from the rake teeth 9, and then passes through a bending detection device to ensure that the detection is not affected by debris.

[0027] Support plates 3 are provided on both sides of the bottom of the top of the shell. The spindle 7 is fixed between the two support plates 3. Several rotating sleeves 6 are rotatably fitted on the outside of the spindle 7. The baffle 5 is fixedly installed on the outer side of the rotating sleeve 6. A damping pad 11 is also provided between the spindle 7 and the rotating sleeve 6. The damping pad 11 is made of rubber. There is a gap between the adjacent baffles 5 and it corresponds to several rake teeth 9. The distance between the edge of the baffle 5 and the rake teeth 9 on both sides is 3 to 5 mm. During the operation of the rotary cleaning machine, the rake teeth 9 pass through the gap. The bent rake teeth 9 will hit the corresponding baffle 5 and make it rotate.

[0028] Under normal circumstances, the rake teeth 9 will pass through the gaps between the baffles 5 without triggering the detection. However, when the rake rod 2 bends, it will cause the ends of the rake teeth 9 to shift laterally. Or, when the rake teeth 9 themselves bend, they will touch the baffles 5 when they approach them, causing the baffles 5 to rotate. At the same time, a damping pad 11 is set between the rotating sleeve 6 and the spindle 7 to ensure that the rotating sleeve 6 cannot rotate arbitrarily. It will only rotate when it is touched and will remain in the position at the time of contact. According to the detection cycle, such as every half day or every day, the staff can check each baffle 5. If a baffle 5 is found to be rotating, it can be known that the rake rod 2 or the rake teeth 9 has been bent and displaced. At this time, the machine can be stopped for further inspection.

[0029] The spindle 7 is also rotatably equipped with a return assembly, which includes a return sleeve 4 rotatably fitted on the spindle 7. A return rod 8 is fixedly installed on the return sleeve 4. The length of the return rod 8 is greater than the length of the rake rod 2. A handle 10 is provided at the end of the return rod 8. After the maintenance of the toothed rake is completed, the handle 10 can be held to rotate the return rod 8. The return rod 8 will then push against the baffle 5 and rotate it to the initial position. All the baffles 5 are at the same angle, which is convenient for the next inspection.

[0030] Considering the usage scenarios of the cleaning machine, electronic equipment was abandoned in favor of a mechanical structure, which ensures the effectiveness of the detection and is not subject to interference. It can clearly show whether the rake teeth are bent, and can also locate the specific bent rake teeth. It is very convenient to use and the modification cost is also very low.

[0031] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
