Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-5 As shown, the utility model provides a construction hopper, which includes:

[0029] The hopper 1 has a top plate 101 installed on its top. The top plate 101 is fixed to the top of the hopper 1 by welding. An inlet 102 for receiving slag is provided on the surface of the top plate 101.

A plurality of bristles 7 are evenly distributed on the surface of the operating member 6 close to the hopper 1, and the outer ends of the bristles 7 extend to the inner wall surface of the hopper 1.

[0032] In this embodiment, after the motor 3 is turned on, the connecting rod 4 can be driven to rotate through the output shaft of the motor 3. During the rotation of the connecting rod 4, the operating part 6 performs a circular motion in the hopper 1, and drives the bristles 7 to brush off the debris adhered to the wall of the hopper 1. The spray component is used to spray water onto the inner wall of the hopper 1, so as to facilitate the automatic cleaning of the hopper 1, effectively save manpower, and have a higher overall degree of automation.

[0033] In some embodiments, multiple brackets 2 are arranged around the hopper 1. The top of the bracket 2 is threadedly connected to the bottom of the top plate 101. By loosening the screw, the hopper 1 can be removed from the top of the bracket 2, which is convenient for the later inspection and maintenance of the hopper 1. In other embodiments, the tops of the brackets 2 are welded and fixed to each other, which can strengthen the connection strength between the hopper 1 and the brackets 2.

[0034] The hopper 1 is supported on the upper part of the slag bucket 11 by the bracket 2 , and a gap for accommodating the slag bucket 11 is reserved between the hopper 1 and the ground, so as to facilitate the hopper 1 to transport slag into the slag bucket 11 .

[0035] The material of the hopper 1 is selected from stainless steel with strong corrosion resistance to prevent the wastewater mixed in the slag from eroding the wall of the hopper 1, thereby effectively extending the service life of the hopper 1.

[0036] In this embodiment, the spray assembly also includes a small water pump 8 installed on the top of the top plate 101. The suction port of the small water pump 8 is fixedly connected with a suction pipe 801, and the suction pipe 801 is externally connected to a water source. The water outlet of the small water pump 8 is fixedly connected with an L-shaped tube 901, and the other end of the L-shaped tube 901 passes through the top plate 101 and is connected with the water outlet head 9; a plurality of nozzles 902 are evenly arranged on the surface of the water outlet head 9; after the water pump is turned on, the water pump transports external water to the inside through the suction pipe 801, and transmits it to the L-shaped tube 901 through the water outlet. After being transmitted to the water outlet head 9 through the L-shaped tube 901, it is evenly sprayed on the inner wall of the hopper 1 through the nozzle 902, and the water flow can fall along the inner wall of the hopper 1 to wash the debris adhered to the inner wall of the hopper 1, thereby further enhancing the cleaning effect of the hopper 1.

[0037] In some embodiments, the connecting rod 4 is vertically arranged at the bottom of the top plate 101, and the connecting rod 4 is fixedly connected to the output shaft of the motor 3; in other embodiments, a protrusion is integrally formed on the surface of the output shaft of the motor 3, and a groove matching the protrusion is formed at the top of the connecting rod 4, and the connecting rod 4 is fixedly connected to the output shaft of the motor 3 by plugging the protrusion into the groove.

[0038] In some embodiments, a hollow rotating shaft 5 is fixedly connected to the bottom of the top plate 101 and at a position outside the output shaft of the motor 3 by screws; the inner wall of the hollow rotating shaft 5 is welded and fixed to the surface of the connecting rod 4, and the inner wall of the hollow rotating shaft 5 does not contact the surface of the output shaft of the motor 3; in other embodiments, a raised limiting ring is provided on the surface of the connecting rod 4, and an annular groove matching the limiting ring is provided on the inner wall of the hollow rotating shaft 5, and the connecting rod 4 is connected and fixed to the hollow rotating shaft 5 by means of mutual clamping between the limiting ring and the annular groove; in still other embodiments, the surface of the connecting rod 4 and the inner wall of the hollow rotating shaft 5 are respectively coated with industrial glue with strong adhesion such as anaerobic glue or instant glue, and the connecting rod 4 is glued and fixed to the inner wall of the hollow bearing.

[0039] In some embodiments, the operating member 6 is welded and fixed on the circumference of the connecting rod 4, and a reinforcing rib 601 is welded between the operating member 6 and the connecting rod 4.

[0043] The working principle of this specific implementation is:

[0044] During the pipe jacking construction, the screw stacking machine continuously excavates and discharges the slag into the hopper 1 through the inlet 102 of the hopper 1. During this process, the handle bar 106 is turned to drive the blocking plate 105 to move out from the arc opening 104, and the hopper 1 discharges slag into the slag bucket 11 through the slag discharge tube 103. After the slag bucket 11 is full, the handle bar 106 is turned to drive the blocking plate 105 to seal the slag discharge tube 103, and the slag bucket 11 is moved to the designated position to discharge the slag, and the screw stacking machine does not need to stop the excavation work; when cleaning the hopper 1, the operator first turns on the water pump and the motor 3 respectively through the controller 10, and turns on the water pump Afterwards, the water pump delivers external water to the interior through the suction pipe 801, and transmits it to the L-shaped tube 901 through the water outlet. After being transmitted to the water outlet head 9 through the L-shaped tube 901, it is evenly sprayed on the inner wall of the hopper 1 through the nozzle 902 to wash away the residual soil on the inner wall of the hopper 1. After the motor 3 is turned on, the output shaft of the motor 3 drives the connecting rod 4 to rotate. During the rotation of the connecting rod 4, the operating part 6 performs a circular motion in the hopper 1 and drives the bristles 7 to brush off the soil adhered to the wall of the hopper 1. When the spray assembly sprays water to the inner wall of the hopper 1, the operating part 6 drives the bristles 7 to brush the inner wall of the hopper 1.
