DETAILED DESCRIPTION

[0026] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0027] In one embodiment, Figure 1-Figure 10 As shown:

The second positioning mechanism 3 includes a second swing frame 7 connected to the right side of the frame 1, and a second driving wheel 8 installed on the second swing frame 7, wherein a motor 9 for driving the second driving wheel 8 to rotate is fixed on the second swing frame 7. The third positioning mechanism 4 includes pedals 10 connected to the left and right inner sides of the frame 1, a pressure rod 11 fixed on the two pedals 10, and a third positioning mechanism 4 connected to the left and right inner sides of the frame 1. The pressure wheels 12 on the two pressure rods 11, the left pressure wheel 12 leans against the first driving wheel 6 driven by the left pressure rod 11, and the right pressure wheel 12 leans against the second driving wheel 8 driven by the right pressure rod 11, a limiting plate 13 is transferred to the two pedals 10, the limiting plate 13 is away from the first driving wheel 6 and the second driving wheel 8, and a clamping gap 14 is formed between the first driving wheel 6 and the second driving wheel 8, a control rod 15 is connected between the two limiting plates 13, an electric cylinder 16 is installed on the rear side of the frame 1, the action rod of the electric cylinder 16 extends forward and is connected to the control rod 15, a brush rod 17 is installed between the two pressure wheels 12, a nozzle 24 is installed on the first swing frame 5, and two rows of nozzles 26 are installed on the top of the nozzle 24, and the opening of the nozzle 26 is tilted downward, and the tilt directions of the two rows of nozzles 26 are opposite to each other.

[0029] A plane 18 is provided on the front section of the top surface of the pedal 10 , and a downwardly inclined inclined surface 19 is provided on the rear section of the top surface of the pedal 10 , and the limiting plate 13 is mounted on the inclined surface 19 .

[0030] Steps 20 are provided on the left and right inner sides of the frame 1, and the pedal 10 is connected to the top of the step 20 through a first rotating shaft 21. The control rod 15 is U-shaped, and both sides are connected to the left and right sides of the frame 1 through second rotating shafts 22. The two second rotating shafts 22 are respectively located below the two pedals 10.

[0031] The length of the wire brush on the brush rod 17 approaches the plane 18 downward.

[0032] A row of bearings is inlaid on each of the left and right sides of the frame 1, and a row of conveying rollers 23 is installed on the frame 1 through the left and right rows of bearings. The conveying rollers 23 are distributed front and back and are located above the step 20. The conveying rollers 23 at the rear end are close to the pedal 10, and the rolling surface height of the conveying rollers 23 is close to the plane 18.

[0033] A baffle 27 is fixed to each of the left and right side walls of the frame 1 . The two baffles 27 cover the pressure rod 11 , and the bottom ends of the baffles 27 are located above the conveying roller 23 .

[0034] A connecting plate 25 is fixed on the frame 1, and is located at the bottom side of the first positioning mechanism 2, the second positioning mechanism 3, and the conveying roller 23. The connecting plate 25 is in the shape of a support, and a discharge port that gradually becomes smaller downward is provided at the bottom of the connecting plate 25, and a discharge pipe is installed on the discharge port.

[0035] Working principle and effect: Start the electric cylinder 16, its action rod extends forward, and pushes the bottom end of the control rod 15 to swing forward, and its top end deflects backward around the second rotating shaft 22, and the top end of the control rod 15 drives the limiting plate 13 to deflect backward, so that the limiting plate 13 is away from the first driving wheel. At this time, the clamping gap 14 becomes larger, and then the bottom end of the steel mesh is inserted into the clamping gap 14. The steel mesh has its own weight and provides downward pressure to the inclined surface 19 on the rear side of the pedal 10, so that one end of the inclined surface 19 deflects downward around the first rotating shaft 21, and drives the flat surface 18 end in front of the pedal 10 to deflect upward, and the two pressure rods 11 are pushed by the two pressure rods 11 to deflect upward, and the two pressure wheels 12 are pushed upward by the two pressure rods 11. 12 rolls over the first drive wheel 6 and the second drive wheel 8 and deflects them backwards until they are pressed against the front of the steel mesh. At this time, the front and rear sides of the electronic device are clamped and fixed, and the water pump is started. The cleaning agent enters the nozzle 24, and part of the cleaning agent is sprayed from the front nozzle 26 to the front of the steel mesh, and part of the cleaning agent is sprayed from the rear nozzle 26 to the back of the steel mesh. Since the front and rear sides of the steel mesh are fixed, not only the two sides are rinsed at the same time, but also the steel mesh will not fall off during the cleaning process. During the cleaning process, the steel mesh is in a vertical state, thereby accelerating the flow speed of the cleaning agent on both sides of the steel mesh, and also allowing the cleaning agent mixed with attachments to be quickly collected into the receiving plate 25.

[0036] like Figures 1 to 3As shown, the first driving wheel 6 is installed on the top end of the first swing frame 5 through a bearing, and the nozzle 24 passes through the top end of the first swing frame 5 from the outside of the first swing frame 5, and then passes through the inside of the first driving wheel 6 and is bent upward to form a first bending portion 28, and is provided with a second bending portion 29 extending horizontally toward the right direction according to the first bending portion 28, and is provided with a transition portion 30 bent backward according to the second bending portion 29, and is provided with a third bending portion 31 bent backward according to the transition portion 30 and extended horizontally to the left, a row of nozzles 26 is located on the front side and installed on the second bending portion 29, and another row of nozzles 26 is located on the rear side and installed on the third bending portion 31, the third bending portion 31 and the transition portion 30 are connected by an adapter 32, so that the third bending portion 31 with the nozzles 26 thereon can rotate back and forth relative to the second bending portion 29, and a bending spring 33 is connected between the adapter 32 and the transition portion 30. The installation mode of the nozzle 24 passing through the first driving wheel 6 will not affect the installation of the first driving wheel 6 on the first swing frame 5. Moreover, the nozzle 24 is distributed on the front and rear sides of the steel mesh in a multi-bend manner, and two rows of nozzles 26 are arranged corresponding to the front and rear parts of the nozzle 24. When cleaning the steel mesh, the front nozzle 26 is aimed at the front of the steel mesh to spray clean water from top to bottom, and the rear nozzle 26 is aimed at the back of the steel mesh to spray and clean from top to bottom, thereby improving the cleaning efficiency.

[0037] In addition to the above, this equipment has a horizontal cleaning function in addition to vertical cleaning, which is specifically manifested in that: when the electric cylinder 16 is powered off, its action rod retracts inward and drags the control rod 15 backward, so that the top of the control rod 15 drives the limiting plate 13 to gradually deflect backward and downward, and the back of the steel mesh relies on the limiting plate 13 and follows the limiting plate 13 to deflect backward and downward, the rear half of the rear of the steel mesh falls on the step 20, and the front half of the rear of the steel mesh falls on the pedal 10 (the steel mesh changes from vertical to horizontal), and the front of the steel mesh is inserted into the bottom of the brush rod 17 in a nearly horizontal manner, and the wire brush (hair) on the brush rod 17 is inserted into the mesh of the steel mesh, and the electric cylinder 16 is started. The machine 9 drives the second driving wheel 8 to rotate, and the second driving wheel 8 is used to rub the right side pressing wheel 12 to rotate, and the right side pressing wheel 12 drives the brush rod 17 to rotate, and the brush rod 17 drives the left side pressing wheel 12 to rotate, and the brush rod 17 also rotates with the wire brush, and uses the rotating action of the brush to rub the steel mesh forward, and at the same time, the brush is inserted into the mesh to clean the residue in the mesh downward, and at the same time, the angle of the nozzle 26 is adjusted to spray the cleaning agent to the steel mesh, so that the residue is cleaned into the connecting plate 25 again, and the rotating action of the brush rod 17 is used to transport the steel mesh to the conveying roller 23 and finally discharge the material. In summary, the present device can not only clean the steel mesh in an upright manner, but also use the wire brush on the brush rod 17 to thoroughly clean the residue in the mesh of the steel mesh while discharging the material out through the brush rod 17 after cleaning. The cleaning equipment first rinses both sides of the steel mesh in an upright position, and then converts the steel mesh to a horizontal position, cleaning the mesh holes while discharging the material, which speeds up the residual cleaning quality and speed.

[0038] A conveying roller 23 is added to the rear side of the frame 1 (the rear side of the pedal 10). When the steel mesh lies down, the rear half of the steel mesh falls on the rear conveying roller 23, and the front half of the steel mesh falls on the pedal 10. When the brush rod 17 guides the steel mesh forward, the steel mesh moves smoothly.

[0039] The above components also have the following effects: when the steel mesh is erected, the first driving wheel 6 will be squeezed by the pressing wheel 12 and will follow the first swing frame 5 to deflect backward and press on the front of the steel mesh, so as to implement positioning on the front of the steel mesh. At the same time, the nozzle 24 will be passed through the first driving wheel 6, and the nozzle 24 will be deflected to the front of the steel mesh, so as to adjust and pull the nozzle 26 closer to the front of the steel mesh. The left and right pressing wheels 12 have the same function. The right pressing wheel 12 not only squeezes the second driving wheel 8 backward to press the second driving wheel 8 on the right side of the front of the steel mesh, but also when the motor 9 drives the second driving wheel 8 to rotate, the rotation force is transmitted to the right pressing wheel 12, and the brush rod 17 is driven by the pressing wheel 12 to rotate. The brush rod 17 is used to convert the steel mesh into a horizontal position, and the mesh is cleaned while being transported forward. Therefore, the positioning structures such as the pressing wheel 12, the first driving wheel 6, and the second driving wheel 8 do not exist in isolation, nor are they limited to a single positioning function. A single component realizes multiple functions.

[0040] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0041] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
