[0002] The concrete screw conveyor is a machine that uses a motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It can convey horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation.

[0003] During the construction of the tunnel project, it was found that the cross-section of the small water conveyance tunnel was small, and the commercial concrete could not be directly transported to the pouring point. It had to be transported by tricycle and pumped to the pouring point. Manual delivery was time-consuming and labor-intensive, with low work efficiency, and could not meet production needs. During the use of the existing concrete screw conveyor, the motor and the screw conveyor were not in a whole, the overall size was too large, and it was inconvenient to move. In addition, the entire equipment was fixed and the height and silo position could not be adjusted, which could not meet production needs. Utility Model Content

[0004] The utility model aims to provide a small-sized water conveyance tunnel secondary lining concrete feeding device to solve the above-mentioned technical problems.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a small-scale water conveyance tunnel secondary lining concrete feeding device, including a hopper bracket, a hopper, a feed port, a barrel bracket, a barrel, a conveying structure, a discharge port, a support bracket, a wheel frame, and a walking wheel, characterized in that: the hopper is installed on the top of the hopper bracket, the feed port is opened at the front end of the hopper, the barrel bracket is fixed at the front end of the hopper with a lower back and a higher front, the barrel is fixed to the barrel bracket, and the rear end of the barrel is installed at the feed port, the conveying structure is installed on the barrel, the discharge port is installed at the front bottom of the barrel, the support bracket is triangularly connected to the bottom of the barrel bracket, the wheel frame is fixed to the bottom of the support bracket, and the walking wheel is installed on the wheel frame.

[0006] Based on the above technical solution, the conveying structure includes a reduction motor, a rotating shaft, a thrust bearing, and a spiral blade. The reduction motor is installed at the front of the barrel, the rotating shaft is installed inside the barrel through the reduction motor, the thrust bearing is installed on the front side of the discharge port through the rotating shaft, and the spiral blade is installed on the rotating shaft.

[0007] Based on the above technical solution, the feed port corresponds to the discharge port through a spiral blade.

[0008] Compared with the prior art, the utility model has the following advantages: the utility model integrates the motor and the barrel and provides walking wheels, which is convenient for placement and adjustment at the site of a small water diversion tunnel project, realizes spiral conveying of concrete, saves labor, is simple to manufacture, easy to operate, and can achieve the purpose of rapid material delivery.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 3 As shown, a small-scale water conveyance tunnel secondary lining concrete feeding device includes a hopper bracket 1, a hopper 2, a feed port 3, a barrel bracket 4, a barrel 5, a conveying structure 6, a discharge port 7, a support bracket 8, a wheel frame 9, and a walking wheel 10, characterized in that: the hopper 2 is installed on the top of the hopper bracket 1, the feed port 3 is opened at the front end of the hopper 2, the barrel bracket 4 is fixed to the front end of the hopper 2 with a lower back and a higher front, the barrel 5 is fixed to the barrel bracket 4, and the rear end of the barrel 5 is installed at the feed port 3, the conveying structure 6 is installed on the barrel 5, the discharge port 7 is installed at the front bottom of the barrel 5, the support bracket 8 is triangularly connected to the bottom of the barrel bracket 4, the wheel frame 9 is fixed to the bottom of the support bracket 8, and the walking wheel 10 is installed on the wheel frame 9.

[0015] The conveying structure 6 includes a reduction motor 11, a rotating shaft 12, a thrust bearing 13, and a spiral blade 14. The reduction motor 11 is installed at the front of the barrel 5, the rotating shaft 12 is installed inside the barrel 5 through the reduction motor 11, the thrust bearing 13 is installed at the front side of the discharge port 7 through the rotating shaft 12, and the spiral blade 14 is installed on the rotating shaft 12.
