Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5 A siphon type mud discharge vehicle hydraulic automatic scraper comprises a mud discharge vehicle 3 which can be moved on a sedimentation tank 1 and a mud suction pipe 2 at the bottom thereof, rolling bearings 18 are fixedly arranged on the outer walls of the lower ends of two adjacent mud suction pipes 2 through a mounting structure, and a rolling bearing center pipe 12 is fixedly arranged inside the two rolling bearings 18, and direction plates 5 are fixedly connected to the two ends of the rolling bearing center pipe 12, respectively, and a pair of scraper brackets 8 are welded to the outer walls of the two sides of the rolling bearing center pipe 12, and a through hole is penetrated through the side surface of one end of each pair of scraper brackets 8 away from the rolling bearing center pipe 12, and a hinged pipe 7 is fixedly arranged in the through hole, four bearings 17 are fixedly arranged on the outer wall of the hinged pipe 7, and a mounting plate 9 is fixedly arranged outside the bearing 17, and two scrapers 6 are fixedly connected to the bottom of the four mounting plates 9 on each side.

[0021] The scraper support 8 is a hollow stainless steel square tube, and the hinged tube 7 is a round, hollow stainless steel tube.

[0022] The limiting device includes a limiting plate 13 and a soft rubber plate 14. The outer walls of the two hinged tubes 7 are sleeved with the limiting plates 13, and the bottom of the limiting plates 13 is fixedly connected to the scraper 6. The outer wall of the hinged tube 7 is fixedly connected to the elastic soft rubber plate 14, and the left end surface of the soft rubber plate 14 is bonded to the limiting plate 13. After the scraper 6 leaves the bottom of the sedimentation tank 1, the limiting plate 13 is driven to rotate and finally remain horizontal through the elastic and automatically recoverable soft rubber plate 14, and the soft rubber plate 14 can prevent the scraper 6 from excessively rotating so that the scraper 6 rotates upward and can resist the influence of water flow and shaking on the scraper 6.

[0023] The direction plate 5 is made by cutting a stainless steel plate.

[0024] An end of the direction plate 5 away from the slope 10 is provided with arc chamfers 11 on the left and right sides, and the two symmetrically arranged arc chamfers 11 form a sharp angle.

[0025] The mounting structure includes a mounting sleeve 15 and a bearing seat 4. The outer wall of the lower end of the mud suction pipe 2 is fixed with the mounting sleeve 15 through a fastening structure. The rear outer wall of the mounting sleeve 15 is integrally formed with a flat surface, and the bearing seat 4 is fastened to the flat surface by screws. A rolling bearing 18 is fixedly installed inside the bearing seat 4.

[0026] The fastening structure includes connecting ears and screw holes 16. A notch is provided at the front end of the mounting sleeve 15, and a pair of connecting ears are integrally formed at the notch. Aligned screw holes 16 are provided on the sides of the connecting ears, and a screw with a nut threaded at one end is inserted into the screw hole 16.

[0027] Working principle: when not working, the mud-discharging vehicle 3 stops at the water inlet end; when working, the mud-discharging vehicle 3 moves back and forth in the sedimentation tank 1 under the command of the electrical control and drives the mud suction pipe 2 and the scraper 6 at the lower end of the mud suction pipe 2 to move at the bottom of the sedimentation tank 1. First, the skimming plate at the bottom of the mud-discharging vehicle 3 is lowered to scrape the floating scum and skim it into the steel skimming trough at the end of the tank. The mud and water scraped and disturbed by the scraper 6 at the bottom of the sedimentation tank 1 are discharged into the mud collecting trough at the side of the sedimentation tank 1 by the mud suction pipe 2 through siphon or pump suction for the next step of processing, and the reciprocating working motion is performed in turn, so as to achieve the purpose of mud suction, mud discharge and scum skimming; when the mud-discharging vehicle 3 travels along the water flow, the direction plate 5 facing the direction of the water flow with the slope 10 at one end is impacted by the water flow, so that the direction plate 5 One end with the slope 10 rotates downward and drives the rolling bearing central main pipe 12, the hinged pipe 7, and the scraper bracket 8 to rotate, so that the scraper 6 at the front end moves downward and fits the bottom of the sedimentation tank 1; when the mud discharge vehicle 3 travels in the reverse direction, it travels against the water flow, and the direction plate 5 with the slope 10 at one end facing the water flow direction is impacted by the water flow, so that the end of the direction plate 5 with the slope 10 rotates downward and drives the rolling bearing central main pipe 12, the hinged pipe 7, and the scraper bracket 8 to rotate in the opposite direction, so that the scraper 6 at the rear end moves downward and fits the bottom of the sedimentation tank 1; the moving scraper 6 scrapes and disturbs the sediment, and when the sediment is scraped, the sediment on the scraper 6 accumulates more and more, and the force is getting greater and greater. This device is mostly used in horizontal flow sedimentation tanks.

[0028] The device can not only scrape up and disturb the sludge at the bottom of the sedimentation tank 1 by the scraper 6 running from one side to the other side of the bottom of the sedimentation tank, but also one end of the scraper 6 that automatically changes its height through the water flow moves downward, and the force becomes greater and greater, and fits the bottom of the sedimentation tank 1, so that the sludge at the bottom of the tank can be scraped very cleanly without dead corners. Therefore, there is no siphon dead corner or leakage in the sludge suction pipe 2, which effectively prevents the sludge in the sedimentation tank 1 from remaining at the bottom, increases the solid content of the discharged sludge, thereby inhibiting the growth of bacteria, ensuring production safety, ensuring water quality, saving energy and reducing emissions, and improving production efficiency.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
