Abstract
Description
Technical Field
[0001] This invention relates to a dredging device, and more specifically, a dredging device for narrow engineering areas. Background Technology
[0002] During construction, silt easily accumulates in narrow areas between buildings and houses, affecting project quality and making cleanup difficult. Existing silt-removal devices, which spray high-speed water into the silt, are prone to instability due to the reaction force of the high-speed water flow. For example, Chinese invention patent document CN209556115U discloses a silt-removal machine for narrow areas. Figure 5 As shown, the technical solution disclosed in this patent document, after spraying high-speed water into the sludge, the reaction force can easily cause the entire device to become unstable, while low-speed water flow is insufficient to achieve a good sludge removal effect, and the narrow area cannot accommodate a heavy and large sludge removal device. Summary of the Invention
[0003] The purpose of this invention is to provide a ground dredging device for narrow engineering areas. It can combine a reaction force pressurized flushing device, a pedal-type pushing device, and a two-way dredging device. The reaction force pressurized flushing device allows the jet box that penetrates into the narrow area to remain stable by utilizing the reaction force of the jetting water flow, without having to make it too large or heavy. This makes it more suitable for narrow areas in engineering projects.
[0004] To achieve the above objectives, the present invention employs the following technical solution:
[0005] A ground dredging device for narrow engineering areas includes a reaction force pressurized flushing device, a pedal-type pushing device, and a two-way dredging device. The reaction force pressurized flushing device includes a jet box, with several jet pipes installed at the bottom of the jet box. The jet pipes pass through the bottom shell of the jet box, and the upper part of the jet box is connected to a longitudinal pipe. The central axis of the longitudinal pipe is in a vertical position. One side of the jet box is connected to a transverse pipe. One end of the longitudinal pipe is connected to a first flexible hose, and one end of the transverse pipe is connected to a second flexible hose. A diagonal rod is installed on one side of the jet box.
[0006] To further achieve the purpose of this invention, the following technical solution can also be adopted: the inner diameter area of the longitudinal tube is greater than the sum of the inner diameter areas of several spray tubes, the longitudinal tube is located at the center of the top surface of the spray box, and the bottom of the spray box is connected to casters.
[0007] The pedal-type pushing device includes a positioning rod and a positioning tube. One end of the positioning rod is inserted into one end of the positioning tube, and the other end of the positioning tube is connected to the pedal. The bottom of the pedal is connected to a serration. One end of the inclined rod is connected to a handle, and the other end of the positioning rod is hinged to the inclined rod. One end of the inclined rod is hinged to the jet box.
[0008] The bidirectional dredging device includes a longitudinal rod, which is connected to the bottom of the spray box. One end of the longitudinal rod is connected to the spray box, and the other end of the longitudinal rod is connected to a scraper. One side of the scraper is located below the spray pipe, and an inclined surface is provided on one side of the scraper. The water jet from the spray pipe can impact the inclined surface.
[0009] A high-pressure water supply device is installed at one end of the second hose. The high-pressure water supply device includes a water tank. Two interface pipes are installed on one side of the bottom of the water tank. The interface pipes pass through the shell of the water tank. One interface pipe is connected to the first hose, one end of the other interface pipe is connected to the second hose, and the other end of the other interface pipe is connected to the outlet of the water pump.
[0010] The advantages of this invention are as follows: This invention combines a reaction force pressurized flushing device, a pedal-type pushing device, and a two-way sludge removal device. The reaction force pressurized flushing device allows the jet box, which is inserted into narrow areas, to remain stable using the reaction force of the sprayed water, without needing to be excessively large or heavy. This makes it more suitable for narrow areas in engineering projects. The pedal-type pushing device allows personnel to push the jet box forward by stepping on the pedal and pressing the handle after it has entered the narrow area. This allows the scraper to scrape off the sludge while it is being flushed away. Simultaneously, the high-pressure water jet from the jet pipe of the reaction force pressurized flushing device impacts the inclined surface of the two-way sludge removal device. The inclined surface allows the high-speed water jet to flow along its surface, ensuring that while the scraper cuts the sludge, the high-speed water jet along the blade impacts the cut portion of the sludge, making it easier to remove.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
[0019] Example 1:
[0020] Ground dredging equipment for narrow engineering areas, such as Figures 1-4 As shown, it includes a reaction force pressurized flushing device, a pedal-type pushing device, and a two-way sludge removal device. The reaction force pressurized flushing device includes a jet box 9, with several jet pipes 15 installed at the bottom of the jet box 9. The jet pipes 15 pass through the bottom shell of the jet box 9. The upper part of the jet box 9 is connected to a longitudinal pipe 6, and the central axis of the longitudinal pipe 6 is in a vertical state. One side of the jet box 9 is connected to a transverse pipe 8. One end of the longitudinal pipe 6 is connected to a first flexible hose 5, and one end of the transverse pipe 8 is connected to a second flexible hose 7. A diagonal rod 2 is installed on one side of the jet box 9.
[0021] This invention combines a reaction force pressurized flushing device, a pedal-type pushing device, and a two-way sludge removal device. The reaction force pressurized flushing device allows the jet box 9, which is inserted into narrow areas, to remain stable by utilizing the reaction force of the sprayed water, without needing to be excessively large or heavy. This makes it more suitable for narrow areas in engineering projects. The pedal-type pushing device allows personnel to push the jet box 9 forward by stepping on the pedal 10 and pressing down on the handle 1 after it has entered the narrow area. This allows the scraper 17 to scrape off the sludge while it is being flushed and cleaned. At the same time, the high-pressure water jet from the spray pipe 15 of the reaction force pressurized flushing device impacts the inclined surface 19 of the two-way sludge removal device. Under the action of the inclined surface 19, the high-speed water jet flows along the surface of the inclined surface 19. This allows the high-speed water jet along the blade of the scraper 17 to impact the cut part of the sludge while the scraper 17 is cutting it, making it easier to remove the sludge.
[0022] Specific material selection and feasibility analysis: The samples we actually produced used the attached drawings in the instruction manual as the blueprints, and were implemented according to the proportions and assembly methods of each component in the drawings. The connections used were common methods such as strong adhesive bonding, welding, riveting, flange connections, and one-piece molding connections. In actual production, the corresponding connection method, thickness, and strength of the connection points can be selected according to the actual connection strength requirements without creative innovation. On the one hand, the central axis of the longitudinal pipe 6 is in a vertical state. Thus, after high-pressure water is introduced into the spray box 9, while the spray pipe 15 sprays high-speed water into the sludge, the longitudinal pipe 6 can allow some water to spray upwards, thereby generating a downward pushing reaction force on the spray box 9, thus improving the stability of the spray box 9 and preventing the spray box 9 from being easily pushed away from the easy area by the water sprayed from the spray pipe 15. During this process, the water sprayed from the first hose 5 will flow into the water tank 12, avoiding water waste. Because the inner diameter area of the longitudinal pipe 6 is larger than the sum of the inner diameter areas of the several spray pipes 15, when the internal water pressure of the spray box 9 is sufficient, the water spray volume of the longitudinal pipe 6 is greater than the sum of the water spray volumes of the several spray pipes 15. The reaction force of the water jet from the longitudinal pipe 6 is greater than the reaction force of the water jet from the several spray pipes 15, thus causing the spray box 9 to be subjected to a downward force as a whole, thereby improving the stability of the spray box 9 and preventing the spray box 9 from shifting its position during the flushing and sludge removal process. The part of the first hose 5 connected to the longitudinal pipe 6 has elasticity and sufficient spare length, thus providing sufficient force relief for the water sprayed from the longitudinal pipe 6.
[0023] Example 2:
[0024] Ground dredging equipment for narrow engineering areas, such as Figures 1-4 As shown, the device includes a reaction force pressurized flushing device, a pedal-type pushing device, and a two-way sludge removal device. The reaction force pressurized flushing device includes a jet box 9, with several jet pipes 15 installed at the bottom of the jet box 9. The jet pipes 15 pass through the bottom shell of the jet box 9. The upper part of the jet box 9 is connected to a longitudinal pipe 6, and the central axis of the longitudinal pipe 6 is vertical. One side of the jet box 9 is connected to a transverse pipe 8. One end of the longitudinal pipe 6 is connected to a first flexible hose 5, and one end of the transverse pipe 8 is connected to a second flexible hose 7. A diagonal rod 2 is installed on one side of the jet box 9. The inner diameter area of the longitudinal pipe 6 is greater than the sum of the inner diameter areas of the several jet pipes 15. The longitudinal pipe 6 is located at the center of the top surface of the jet box 9, and the bottom of the jet box 9 is connected to casters 18.
[0025] The fact that the inner diameter area of the longitudinal pipe 6 of the present invention is greater than the sum of the inner diameter areas of the multiple spray pipes 15 makes it convenient to ensure that when the water pressure at the inlet of the second hose 7 is sufficient, the water output of the longitudinal pipe 6 is greater than the sum of the water output of the multiple spray pipes 15. This makes the reaction force generated by the water spray from the longitudinal pipe 6 greater than the reaction force generated by the water spray from the multiple spray pipes 15, thereby preventing the spray box 9 from being lifted by the water pressure and allowing the spray box 9 to spray water onto the ground more stably.
[0026] Example 3:
[0027] Ground dredging equipment for narrow engineering areas, such as Figures 1-4 As shown, the device includes a reaction force pressurized flushing device, a pedal-type pushing device, and a two-way sludge removal device. The reaction force pressurized flushing device includes a jet box 9, with several jet pipes 15 installed at the bottom of the jet box 9. The jet pipes 15 pass through the bottom shell of the jet box 9. The upper part of the jet box 9 is connected to a longitudinal pipe 6, and the central axis of the longitudinal pipe 6 is in a vertical position. One side of the jet box 9 is connected to a transverse pipe 8. One end of the longitudinal pipe 6 is connected to a first flexible hose 5, and one end of the transverse pipe 8 is connected to a second flexible hose 7. A diagonal rod 2 is installed on one side of the jet box 9. The pedal-type pushing device includes a positioning rod 3 and a positioning tube 4. One end of the positioning rod 3 is inserted into one end of the positioning tube 4, and the other end of the positioning tube 4 is connected to a pedal 10. The bottom of the pedal 10 is connected to a serration 11. One end of the diagonal rod 2 is connected to a handle 1, and the other end of the positioning rod 3 is hinged to the diagonal rod 2. One end of the diagonal rod 2 is hinged to the jet box 9.
[0028] The longitudinal pipe 6 of this invention is located at the center of the top surface of the spray box 9, which facilitates the longitudinal pipe 6 in guiding the water outlet of the spray box 9 upward. The resulting reaction force can act on the center of the top surface of the spray box 9, thereby better utilizing the reaction force to press down the spray box 9. This improves the stability of the spray box 9 when the spray pipe 15 is washing the ground, preventing the spray box 9 from being easily lifted by the sprayed water. The pedal-type pushing device can achieve [the desired effect] after the spray box 9 is inserted into a narrow area. Figure 2 In this state, by having a person step on pedal 10 and press down on handle 1, the positioning rod 3 and positioning tube 4 are retracted. Because the person is stepping on pedal 10, the positioning rod 3 and positioning tube 4 cannot move, thereby pushing the jet box 9 forward to achieve... Figure 3 This allows the scraper 17 to scrape off the silt while it is being flushed and cleaned. At the same time, the high-pressure water jet from the jet pipe 15 of the reaction force pressurizing flushing device impacts the inclined surface 19 of the bidirectional sludge removal device. Under the action of the inclined surface 19, the high-speed water jet can flow along the surface of the inclined surface 19. Thus, while the scraper 17 is cutting the silt, the high-speed water jet along the blade can impact the cut part of the silt, making it easier to remove the silt.
[0029] Example 4:
[0030] Ground dredging equipment for narrow engineering areas, such as Figures 1-4As shown, the device includes a reaction force pressurized flushing device, a pedal-type pushing device, and a two-way sludge removal device. The reaction force pressurized flushing device includes a jet box 9, with several jet pipes 15 installed at the bottom of the jet box 9. The jet pipes 15 pass through the bottom shell of the jet box 9. The upper part of the jet box 9 is connected to a longitudinal pipe 6, and the central axis of the longitudinal pipe 6 is vertical. One side of the jet box 9 is connected to a transverse pipe 8. One end of the longitudinal pipe 6 is connected to a first flexible hose 5, and one end of the transverse pipe 8 is connected to a second flexible hose 7. A diagonal rod 2 is installed on one side of the jet box 9. The two-way sludge removal device includes a longitudinal rod 16, which is connected to the bottom of the jet box 9. One end of the longitudinal rod 16 is connected to the jet box 9, and the other end of the longitudinal rod 16 is connected to a scraper 17. One side of the scraper 17 is located below the jet pipes 15, and a slope 19 is provided on one side of the scraper 17 so that the water jets from the jet pipes 15 can impact the slope 19.
[0031] When the scraper 17 is pushed to clean the silt attached to the ground, the water jet from the spray pipe 15 can impact the surface of the inclined plane 19. Under the action of the inclined plane 19, the high-speed water jet can flow along the surface of the inclined plane 19. Thus, while the scraper 17 is cutting the silt, the high-speed water jet along the blade can impact the cut part of the silt, making it easier to clean the silt.
