Description

Technical Field

[0001] This utility model relates to a sewage discharge device for a sewage suction truck, belonging to the field of sewage discharge technology for sewage suction trucks. Background Technology

[0002] Different cities and regions often require different discharge valves due to varying usage habits or different valve connection methods. Some discharge valves require holes to be drilled at the top and bottom of the tank during installation. The valve is inserted into the tank through the top, and then engages with the hole at the bottom of the tank, allowing the bottom hole to open when drainage is needed and close when drainage is not required.

[0003] Utility model patent CN222798156U discloses a discharge valve for a septic tank truck, including an upper orifice plate, a lower orifice plate, and a valve body. The other end of the valve body extends into the tank. A matching lead screw and nut are installed inside the valve body. One end of the lead screw extends out of the upper orifice plate and is connected to a handle, while the other end extends out of the valve body and is connected to a valve plug. The valve plug is an inverted truncated cone, narrower at the bottom and wider at the top. A sealing ring groove is provided around the lower orifice plate, and a sealing ring is installed within the groove. Rotating the handle lowers the lead screw, causing the two sides of the valve plug connected to the lead screw to enter the lower orifice and press against the sealing ring, thus sealing the bottom orifice of the tank.

[0004] However, the above-mentioned patented solution has the following technical problems in actual use: the manure has poor fluidity and is easily blocked at the manure outlet when it is discharged, which affects the discharge. In addition, the outlet is located in the middle of the bottom of the tank, and the manure tends to accumulate at the bottom of the tank and cannot flow smoothly to the middle outlet.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a sewage discharge device for a sewage suction truck, which can prevent sewage from accumulating in the dead corners of the tank and being unable to be discharged. In addition, the spiral blades push the sewage downwards to avoid sewage from accumulating at the discharge pipe.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A sewage discharge device for a sewage suction truck includes a tank body, a sewage discharge pipe at the bottom of the tank body, a rotating shaft inside the tank body, and a sealing plate installed at the lower end of the rotating shaft, with the sealing plate facing the inner end of the sewage discharge pipe. The lower surface of the sealing plate is vertically fixed with a plurality of second scrapers, and the inner side of the second scrapers is fixed with a plurality of spiral blades from top to bottom.

[0008] Furthermore, the outer ring of the lower surface of the sealing plate is provided with a rubber ring, the outer ring of the sealing plate is matched with the inner port of the sewage pipe, and the top of the second scraper is located on the inner side of the matching position of the inner port of the sealing plate and the sewage pipe.

[0009] Furthermore, the second scraper is perpendicular to the inner wall of the discharge pipe, and the second scraper is close to the inner wall of the discharge pipe, so that the inner ends of the multiple spiral blades form a circular discharge channel.

[0010] Furthermore, a plurality of first scrapers are provided around the bottom wall of the tank, and the first scrapers are inclined. A sliding sleeve is fitted at the lower end of the rotating shaft, and each first scraper is fixed to the outside of the sliding sleeve by a connecting rod.

[0011] Furthermore, the sliding sleeve is axially slidably mounted on the rotating shaft, and the inner ring of the sliding sleeve is axially provided with a sliding groove. A first rib is axially provided at the lower end of the rotating shaft, and the first rib cooperates with the sliding groove.

[0012] Furthermore, a pulley is provided on the top of the tank. The pulley is rotatably mounted on the top of the tank via a first bearing. The upper end of the shaft, which extends beyond the top of the tank, is installed in the central hole of the pulley. The pulley is driven by a belt drive system.

[0013] Furthermore, the central hole of the pulley is provided with a sliding groove, and the upper end of the shaft is provided with a second rib, the sliding groove cooperating with the second rib.

[0014] Furthermore, the top of the rotating shaft is connected to the telescopic rod of the electric actuator via a second bearing.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: During the rotation of the shaft, the first scraper is driven to rotate. Due to the inclined setting of the first scraper, the manure at the bottom of the tank can be pushed towards the middle discharge pipe, thus preventing the manure from accumulating in the dead corners of the tank and being unable to be discharged.

[0016] The rotating shaft drives the second scraper and the spiral blade to rotate. The second scraper scrapes off the feces stuck to the discharge pipe, while the spiral blade discharges the feces downward to prevent the feces from accumulating at the discharge pipe.

Detailed Implementation

[0020] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, this utility model provides a sewage discharge device for a sewage suction truck, including a tank body 1, a sewage discharge pipe 2 at the bottom of the tank body 1, a rotating shaft 3 inside the tank body 1, and a sealing plate 8 installed at the lower end of the rotating shaft 3, with the sealing plate 8 facing the inner end of the sewage discharge pipe 2. A plurality of second scrapers 9 are vertically fixed around the lower surface of the sealing plate 8, and a plurality of spiral blades 10 are fixed from top to bottom on the inner side of the second scrapers 9.

[0022] The lower surface of the sealing plate 8 is provided with a rubber ring (not shown in the figure). The outer ring of the sealing plate 8 is matched with the inner port of the sewage pipe 2. The top of the second scraper 9 is located on the inner side of the matching position of the inner port of the sealing plate 8 and the sewage pipe 2.

[0023] The second scraper 9 is perpendicular to the inner wall of the manure pipe 2, and the second scraper 9 is close to the inner wall of the manure pipe 2, so that the inner ends of the multiple spiral blades 10 form a circular manure discharge channel.

[0024] The bottom wall of the tank 1 is provided with a plurality of first scrapers 4, and the first scrapers 4 are arranged at an angle (e.g. Figure 3 The lower end of the rotating shaft 3 is fitted with a sliding sleeve 6, and each first scraper 4 is fixed to the outside of the sliding sleeve 6 by a connecting rod 5.

[0025] The sliding sleeve 6 is axially slidably mounted on the rotating shaft 3, and the inner ring of the sliding sleeve 6 is axially provided with a sliding groove. A first rib 7 is axially provided at the lower end of the rotating shaft 3, and the first rib 7 cooperates with the sliding groove. During the rotation of the rotating shaft 3, the sliding sleeve 6 can be driven to rotate, thereby driving the first scraper 4 to rotate. When the rotating shaft 3 moves up and down, the sliding sleeve 6 slides relative to the rotating shaft 3, so that the first scraper 4 is always in contact with the bottom wall of the tank body 1.

[0026] The top of the tank body 1 is provided with a pulley 12, which is rotatably mounted on the top of the tank body 1 via a first bearing 13. The upper end of the rotating shaft 3, which extends beyond the top of the tank body 1, is installed in the central hole of the pulley 12. The pulley 12 is driven by a belt drive system 16.

[0027] The pulley 12 has a sliding groove in its central hole, and the upper end of the shaft 3 has a second rib 11. The sliding groove cooperates with the second rib 11. When the pulley 12 rotates, it can drive the shaft 3 to rotate, and the shaft 3 can slide up and down relative to the pulley 12.

[0028] The top of the rotating shaft 3 is connected to the telescopic rod of the electric actuator 15 via the second bearing 14.

[0029] The specific working principle of this utility model: The electric actuator 15 drives the rotating shaft 3 to slide up and down relative to the pulley 12. When the rotating shaft 3 moves down, it pushes the sealing plate 8 to block the inner opening of the discharge pipe 2. When the rotating shaft 3 moves up, it discharges the manure. During the rotation of the rotating shaft 3, it drives the first scraper 4 to rotate. Because the first scraper 4 is set at an angle, it can push the manure at the bottom of the tank 1 towards the discharge pipe 2 in the middle, preventing the manure from accumulating in the dead corners of the tank 1 and being unable to be discharged.

[0030] When discharging manure, the rotating shaft 3 drives the second scraper 9 and the spiral blade 10 to rotate. The second scraper 9 scrapes off the manure stuck to the manure discharge pipe 2, while the spiral blade 10 discharges the manure downwards to prevent the manure from accumulating at the manure discharge pipe 2.
