[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0023] Combined with appendix Figure 1 It can be seen that the equipment includes a grouting device 1, which includes a mixing structure, a power structure and a support structure. A material auxiliary conveying device is provided next to the grouting device 1. The material auxiliary conveying device includes a material frame 2. Support plates 3 are fixed on both sides of one end of the material frame 2. A sprocket structure 4 is provided on one side of the support plate 3. Several connecting rods 5 are fixed between the two sprocket structures 4. A material transport bucket 6 is sleeved on the side of the connecting rod 5. A stop bar structure and a conveying plate structure are provided at the top of the support plate 3. A moving structure is provided on the lower side of the material frame 2. The moving structure includes a wheel frame fixed on the side of the material frame 2. Rollers 9 are rotatably provided on the side of the wheel frame. A push handle is fixed on one side of the material frame 2. The sprocket structure 4 is electrically connected to an external power source.

[0024] Combined with appendix Figure 2 , 34. It can be seen that a baffle 6.1 is fixed on the lower side of the material transport hopper 6. During the downward movement of the material transport hopper 6, the baffle 6.1 can hit the upper edge of the left side of the material frame 2, causing the material transport hopper 6 to tilt so that its opening faces the material inside the material frame 2, so as to facilitate the loading of the material. As the sprocket structure 4 continues to transport, the material transport hopper 6 can gradually return to its upright position and maintain a vertical state to facilitate the transport of the material. The baffle structure includes a connecting rod and a connecting plate fixed to one end of the two support plates 3. A baffle 7 is fixed between the two connecting plates. The baffle 7 can block the material transport hopper 6 during the upward transport process. Plate 6.1 causes the material transport hopper 6 to tilt and flip. During the tilting and flipping process, the material in the material transport hopper 6 will be poured into the conveying hopper 8. The bottom of the material frame 2 is tilted towards the sprocket structure 4, which facilitates the accumulation of material towards the material transport hopper 6 and makes it easier for the material transport hopper 6 to hold the material. The conveying plate structure includes a folding rod fixed to one end of two support plates 3. The conveying hopper 8 is fixed between the two folding rods. A clamping plate is fixed to the lower side of the conveying hopper 8. An inlet 1.1 is fixed to one side of the mixing structure. The clamping plate is engaged with the inlet 1.1 side, which can fix the position of the material auxiliary conveying equipment to facilitate the conveying of materials.

[0025] The working principle of this application is as follows: In the process of conveying grouting materials, the material frame 2 is first filled with materials, and then the material auxiliary conveying equipment is moved to the side of the grouting equipment 1, and the card plate on the lower side of the conveying hopper 8 is engaged with the inlet 1.1 side. Then the sprocket structure 4 is started, and the sprocket structure 4 can drive several material conveying hoppers 6 to rotate counterclockwise.

[0026] When the material transport hopper 6 located below the sprocket structure 4 moves, the baffle 6.1 first hits the upper left edge of the material frame 2, causing the material transport hopper 6 to tilt so that its opening faces the material inside the material frame 2, facilitating the loading of the material. As the sprocket structure 4 continues to transport, the material transport hopper 6 gradually returns to its upright position, maintaining a vertical upward transport. Then, during the upward transport of the material transport hopper 6, the baffle 6.1 hits the side of the stop bar 7, causing the material transport hopper 6 to tilt and flip. During the tilting and flipping process of the material transport hopper 6, the material in the material transport hopper 6 will pour into the conveying hopper 8, thus realizing the material transport. After flipping, the material transport hopper 6 will continue to move downward for the next loading.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
