A conveyor belt 2 is installed inside the conveyor frame 1. When the conveyor belt 2 starts, it can move and transport materials reaching above it to the right. A feed pipe 3 is installed above the conveyor frame 1. A support frame 4 is fixedly connected to the outside of the feed pipe 3, supporting and fixing the feed pipe 3 so that the feed pipe 3 can be stably placed directly above the conveyor belt 2. A feed hopper 5 is fixedly connected to the upper surface of the feed pipe 3, increasing the feeding space above the feed pipe 3 and improving feeding efficiency. A discharge port 6 is opened on the lower right side of the feed pipe 3. When the material reaches the bottom of the feed pipe 3 through the feed hopper 5, it can be moved out of the feed pipe 3 through the discharge port 6 and moved to the right as the conveyor belt 2 runs.

The guide plates 7 are arranged in an alternating structure and fixedly connected inside the feed pipe 3. The alternating guide plates 7 can guide the movement of the material entering the feed pipe 3 and delay the movement distance of the material inside the guide plates 7. When the running speed of the conveyor belt 2 needs to be controlled to match the material feeding speed, the material accumulates inside the feed pipe 3. The guide plates 7 will support the material above it. The alternating guide plates 7 can support most of the material inside the feed pipe 3, so that only a small part of the material at the bottom of the feed pipe 3 will directly press against the conveyor belt 2. This can avoid excessive accumulation of material, which would increase the resistance of the conveyor belt 2 and cause the motor to burn out.

[0032] The right surface of the feeding pipe 3 is fixedly connected with baffles 8 on the front and back sides, the baffles 8 are located on the right side of the discharge port 6, the baffles 8 are arranged to regulate the material moving to the right through the discharge port 6, so as to avoid the risk that the material on the conveying belt 2 leaks from the edge of the conveying belt 2, and the concrete falling off may be stuck in the roller or the carrier roller, thereby increasing the equipment wear and tear, the right side of the feeding pipe 3 is provided with an L-shaped adjusting frame 9, the left side surface of the L-shaped adjusting frame 9 is matched with the right side surface of the feeding pipe 3, the front and back side surfaces of the L-shaped adjusting frame 9 are matched with the outer walls of the two baffles 8 on the right side of the feeding pipe 3, the L-shaped adjusting frame 9 can control the opening size of the discharge port 6 when moving up and down, thereby controlling the thickness of the material on the conveying belt 2, and the conveying amount of the concrete material per unit time can be accurately controlled, and the downtime waiting or backlog is reduced.

[0033] The moving unit 10 is arranged above the L-shaped adjusting frame 9, the moving unit 10 comprises a fixed plate 101 fixedly connected to the right side surface of the feeding pipe 3, the bottom surface of the fixed plate 101 is fixedly connected with an electric telescopic rod 102, the bottom end of the electric telescopic rod 102 is fixedly connected with the inner bottom surface of the L-shaped adjusting frame 9, the electric telescopic rod 102 can drive the L-shaped adjusting frame 9 to move up and down when starting, the inner bottom surface of the L-shaped adjusting frame 9 is fixedly connected with a guide rod 103, the upper end of the guide rod 103 penetrates through the fixed plate 101, the guide rod 103 is inserted between the fixed plate 101, so that the guide rod 103 can only move up and down relative to the fixed plate 101, thereby guiding and limiting the L-shaped adjusting frame 9, and the risk of deviation of the L-shaped adjusting frame 9 during up and down movement is reduced.

[0034] Referring to Figs. 1-3 The bottom surface of the guide plate 7 is fixedly connected with a supporting inclined plate 11, one end of the supporting inclined plate 11 away from the guide plate 7 is fixedly connected with the inner wall of the feeding pipe 3, the supporting inclined plate 11 can support and limit the bottom of the guide plate 7, a triangular supporting structure is formed between the supporting inclined plate 11, the guide plate 7 and the inner wall of the feeding pipe 3, which can improve the stability and strength of the guide plate 7 during use, a guide groove 12 is formed in the right side surface of the feeding pipe 3, a guide block 13 is fixedly connected to the left side surface of the L-shaped adjusting frame 9, the guide block 13 is slidably connected with the inside of the guide groove 12, the guide block 13 can only move in a straight line in the up and down direction inside the guide groove 12, thereby further guiding and limiting the movement of the L-shaped adjusting frame 9, so that the left side surface of the L-shaped adjusting frame 9 remains matched with the right side surface of the feeding pipe 3, and the L-shaped adjusting frame 9 is prevented from being deformed and deviated under the impact of the material.

[0035] Working principle: start the conveyor belt 2, and make the material through the feed hopper 5 into the feed pipe 3, the material will move down along the inclined surface of the guide plate 7 to the conveyor belt 2, and finally through the discharge port 6 to move out of the feed pipe 3 to the right side for conveying, the staff can start the electric telescopic rod 102 to drive the L-shaped adjusting frame 9 to move up and down for adjusting, adjust the opening size of the discharge port 6, accurately control the conveying amount of the concrete material per unit time, the L-shaped adjusting frame 9 and the baffle 8 can regulate the material passing through the discharge port 6, avoid the material from stacking or falling on both sides, when the L-shaped adjusting frame 9 moves up and down for adjusting, the fixed plate 101, the guide rod 103, the guide groove 12 and the guide block 13 can guide and limit the movement of the L-shaped adjusting frame 9, avoid the L-shaped adjusting frame 9 from deviating under the impact of the material, affect the use effect and service life of the device.

[0036] When the running speed of the conveyor belt 2 is lower than the speed of the material entering the inside of the feed pipe 3, the guide plate 7 can support most of the material above the inside of the feed pipe 3, so that only part of the material at the bottom of the feed pipe 3 can be stacked and pressed on the conveyor belt 2, which can reduce the resistance of the conveyor belt 2 and avoid the motor from burning out.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
