[0003] In recent years, the domestic demand for highway sweepers has become increasingly urgent. Some manufacturers have also upgraded the original sanitation sweepers and construction sweepers to meet the high-speed sweeping needs of users. Domestic highway sweepers basically adopt two modes: suction sweeping and pure sweeping. Pure sweeping sweepers cannot collect and sweep dust, which is easy to cause secondary pollution. Existing suction sweepers are easy to clog the suction pipe when sweeping heavily polluted roads with a large number of branches, leaves and mud or large pieces of garbage such as rubber on the road. When the suction pipe is clogged, the cleaning effect is affected and manual cleaning is required, which affects the operating efficiency of the vehicle.

[0004] For this reason, a cleaning suction cup with an anti-clogging self-dredging suction pipe is designed to overcome the above problems. Summary of the invention

[0016] In the description of the present invention, it is necessary to understand that the orientation or position relationship indicated by the terms such as "up", "down", "left", "right", "inside", "outside", "horizontal" and "vertical" is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or original referred to must have a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] The present invention will be described in detail below with reference to the accompanying drawings: Figure 1 As shown, a cleaning suction cup with an anti-clogging self-draining suction pipe comprises a cleaning suction cup 8 installed on a high-speed cleaning vehicle and a suction pipe 4 connected to the cleaning suction cup 8, a cleaning tool is installed on one side of the cleaning suction cup 8, and a through hole (not shown in the figure) penetrating the cleaning suction cup is arranged in the middle position of the cleaning suction cup, the side of the through hole close to the cleaning tool is a feed port, and the other side thereof extends outward to form an outwardly convex discharge port 11, the discharge port 11 is connected to one end of the suction pipe 4, and the other end of the suction pipe 4 is extended into the bottom plate 1 of the garbage bin of the high-speed cleaning vehicle and is fixed to the garbage bin (not shown in the figure) through a connecting piece, and a cleaning device and an auxiliary cleaning device are respectively installed at the discharge port 11 and on the side of the suction pipe 4, which are used to clean the discharge port of the cleaning suction cup 8 and the inner wall of the suction pipe 4, and to prevent the sucked-in large pieces of garbage from clogging the discharge port 11 or the suction pipe 4, so as to ensure the normal operation of the whole.

[0018] The cleaning device is composed of a high-pressure pulse valve 9 and a rotary cutting water nozzle 10. The high-pressure pulse valve 9 is embedded in the side of the discharge port 11 of the cleaning suction cup 8 and is connected to the discharge port 11. It is used to pulse the discharge port 11 and the inside of the suction pipe 4 to break through the large pieces of garbage blocking the discharge port 11 or the inner wall of the suction pipe 4. One end of the rotary cutting water nozzle 10 is connected to an external water source, and the other end is inserted into the discharge port 11 and installed on the inner wall of the suction pipe 4 to spray water into the suction pipe 4 along the pipe wall to avoid silt accumulation and blockage.

[0019] The connecting piece is a clamp 7, and an upper straw flange 3 and a lower straw flange 6 are respectively provided at the upper and lower ends of the straw. After the upper straw flange 3 and the lower straw flange 6 are connected to the straw through the clamp 7, the straw is respectively connected and fixed to the discharge port of the cleaning suction cup and the inner wall of the garbage bin through the upper straw flange 3 and the lower straw flange 6.

[0020] The connecting member is at least one supporting tube 2 arranged between the upper flange 3 of the suction tube and the bottom plate 1 of the trash bin. One end of each supporting tube 2 is connected to the bottom surface of the upper flange 3 of the suction tube by bolts, and the other end is welded to the top surface of the bottom plate 1 of the trash bin. An auxiliary cleaning device is installed on the connecting member.

[0021] The auxiliary cleaning device is a vibrating hammer 5 with a motor installed on the support tube 2. The vibrating hammer 5 is turned on to vibrate and drive the straw to shake to shake off the mud and sand adhering to the inner wall of the straw. The vibrating hammer is a conventional technology and can also be replaced by other shaking devices with vibration function to meet actual needs.

[0022] The suction pipe 4 is a corrugated hose. When the cleaning suction cup 8 is cleaning, the corrugated hose 4 will creep under the action of suction and vehicle shaking, realizing the principle of self-dredging and reducing the blockage of the suction pipe 4. When the corrugated hose is sprayed by the rotary cutting water nozzle 10, the water flow rises along the spiral line of the suction pipe under the action of suction, washing the mud and sand adhering to the wall of the suction pipe 4, improving the cleaning effect and avoiding accumulation and blockage. The clamp 7 is a U-shaped quick-release clamp, which is convenient for disassembly and maintenance and ensures stability after connection.

[0023] The working process of the present invention is as follows: After the installation of the present invention is completed, a channel mainly composed of a corrugated hose is formed from the cleaning suction cup to the inside of the garbage bin, and the garbage enters the inside of the garbage bin through the composite cleaning suction cup, the lower flange of the suction pipe, the corrugated hose, and the upper flange of the suction pipe; a high-pressure pulse valve and a rotary cutting water nozzle are installed at the discharge port of the cleaning suction cup. During the cleaning operation, the rotary cutting water nozzle sprays water into the suction pipe along the pipe wall, and the water flow rises along the spiral line of the corrugated hose under the action of suction force, washing away the mud and sand adhering to the suction pipe wall to avoid accumulation and blockage.

[0024] During cleaning operations, under the action of suction and vehicle shaking, the corrugated hose will wriggle, realizing the principle of self-dredging, thereby reducing blockage of the suction pipe.

[0025] When large pieces of garbage enter the pipeline and cannot be cleared through pipe peristalsis, the high-pressure pulse valve and the vibrating hammer installed on the support pipe can be opened to break the large pieces of garbage or push them out of the composite cleaning suction cup to avoid blockage and affect the cleaning operation.

[0026] The cleaning suction cup with anti-clogging self-draining suction pipe designed by the present invention can solve the blockage of most garbage pile pipes. In order to facilitate the garbage unblocking and cleaning and suction cup maintenance in special circumstances, the (composite) cleaning suction cup is connected to the lower flange of the self-draining suction pipe through a U-shaped quick-release clamp.

[0027] The specific embodiments described herein are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed by the present invention shall still be covered by the claims of the present invention.
