The slider 34 is pushed and pulled along the slide rail 14 by an electric push rod 37 to adjust the height of the discharge frame 36 at the end of the conveying frame 31.

[0021] In this embodiment, the feed hopper 22 includes an upper frustoconical hopper body and a rectangular discharge cylinder located at the bottom of the hopper body. A baffle plate 23 is provided on the rectangular discharge cylinder. The baffle plate passes through a perforation on one side wall of the rectangular discharge cylinder, and its end abuts against the inner wall of the rectangular discharge cylinder. The electric push rod is an electric hydraulic push rod. The slider is limited to the slide rail and moves back and forth along the slide rail. A pad is provided on the bottom surface of the conveying frame and near the end of the discharge frame for supporting the mixer cylinder wall. The upper part of the pad can be hinged to the bottom surface of the conveying frame through a pin to realize the adjustable angle of the pad and increase the adaptability of the pad support. The discharge frame is a U-shaped structure. The U-shaped structure is set perpendicular to the conveying frame. The U-shaped space inside the U-shaped structure is a material transmission channel. The bottom surface of the pad is an inwardly concave arc surface for fixing it to the mixer cylinder wall.

[0022] In this embodiment, the push-pull trolley includes a trolley body, moving wheels, and a push-pull handle. The moving wheels are equipped with a locking assembly, which includes a U-shaped part and an anchor. The U-shaped part is overturned and passes through a hole in the moving wheel. The U-shaped part is anchored to the ground by the anchor to achieve stable locking of the moving wheel. The slide is a strip-shaped channel on the surface of the trolley body. The strip-shaped channel is set along the length of the trolley body.

[0023] Example 2 A concrete proportioning and feeding device includes a push-pull trolley, a concrete conveying device mounted on the upper surface of the push-pull trolley, a concrete initial mixing device mounted above the concrete conveying device, and casters mounted on the bottom surface of the push-pull trolley. By using the casters mounted on the bottom surface of the conveying device, the traditional fixed structure can be designed to move freely to any position, thereby enabling it to be used in conjunction with various mixers to convey materials into the mixer and achieve the feeding effect.

[0024] The concrete conveying device includes a hinged frame located on the upper surface of the push-pull trolley. The hinged frame includes a pin and a rotating block. A conveying frame is installed on the upper surface of the rotating block. An electric conveying roller is installed inside the conveying frame. The electric conveying roller can convey concrete raw materials and is mainly used to transport raw materials such as cement, aggregates, and sand from the storage bin to the concrete mixer to ensure a continuous supply of raw materials during the mixing process.

[0025] In this embodiment, the pad and the discharge frame are arranged adjacent to each other. The pad is located on the bottom surface of the conveying frame, and the discharge frame is located at the right end of the conveying frame. The pad is supported by the feed port of the mixer, which can support the right end of the conveying frame. The discharge frame can achieve a simple transfer effect on the conveyed material.

[0026] In this embodiment, the slide is located on the bottom surface of the push-pull trolley. An electric push rod is installed on the outer surface of the slide. A slider is installed at the output end of the electric push rod. An inclined support rod is installed on the upper surface of the slider through a pin. Since the top end of the inclined support rod is connected to the bottom surface of the conveying frame through the pin, the electric push rod pushes the slider, thus providing a thrust to the left end of the inclined support rod, causing the left end, i.e. the lower end, of the inclined support rod to move to the right. Furthermore, since the top end of the inclined support rod is hinged to the bottom surface of the conveying frame, the right end of the inclined support rod can be lifted, thereby changing the angle of the inclined support rod and lifting the right end of the conveying frame through the inclined support rod.

[0027] In this embodiment, the concrete initial mixing device includes two support frames and a feeding hopper. The support frame includes a collection frame and a discharge cylinder. The support frame has a portal frame structure. Both support frames are located on the upper surface of the push-pull trolley. The collection frame is installed on the upper surface of the two support frames. The discharge cylinder is installed on the bottom surface of the collection frame. A baffle plate is placed on the outer surface of the discharge cylinder. By installing the baffle plate inside the discharge cylinder, the size of the discharge port of the discharge cylinder can be controlled, thereby controlling the discharge amount of material.

[0028] In this embodiment, the push-pull trolley includes a push-pull handle, a trolley body, and multiple movable wheels. The push-pull handle is located on the left side of the push-pull trolley, and each movable wheel is located on the bottom surface of the push-pull trolley. The device can be easily moved by the push-pull handle and multiple movable wheels, and a locking component is installed in the movable wheels to fix the device.

[0029] In use, the staff first moves the device to a suitable position using the casters. Then, the electric push rod in the drive assembly is activated to push the slider, which changes the angle of the inclined support rod, thereby adjusting the height of the right end of the conveying frame. Finally, the staff pours various materials into the collection frame according to the proportions, and at the same time, the electric conveying roller in the device is activated to transport the ingredients to the mixer for mixing.
