[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: an automatic weighing device for the raw materials of an environmental protection concrete formula, including the main body 1 of the automatic weighing device. There is a mixing hopper 5 on the main body 1 of the automatic weighing device, and a raw material storage hopper 3 is arranged on the side of the mixing hopper 5. The upper opening of the raw material storage hopper 3 is of an isosceles trapezoid structure, and the narrow side of the raw material storage hopper 3 faces the mixing hopper 5. This structure enables the raw material storage hopper 3 to be spliced by the isosceles trapezoid structure to form a polygonal structure, and the addition and subtraction of the raw material storage hopper 3 can be carried out according to the quantity of the raw materials. A raw material discharge port 301 is opened at the bottom of the raw material storage hopper 3, and a screw weighing conveyor 302 is installed at the raw material discharge port 301 of the raw material storage hopper 3. And a movable support frame 303 is connected to the bottom of the raw material storage hopper 3. The lower part of the raw material storage hopper 3 is of a conical structure, and the raw material storage hopper 3 is fixedly welded to the movable support frame 303. This structure can conduct the weighing and conveying process of different raw materials through the screw weighing conveyor 302 by introducing different raw materials into the raw material storage hopper 3, and the raw materials are fed into the mixing hopper 5 for the unified conveying of the proportioned raw materials. A base 2 is arranged at the bottom of the main body 1 of the automatic weighing device, and a fixed support frame 502 is fixedly welded to the middle of the upper end of the base 2. The fixed support frame 502 is screwed and fixed to the mixing hopper 5, and the movable support frame 303 is screwed and fixed to the base 2. This structure enables the main body 1 of the automatic weighing device to form a basic positioning process through the base 2, enables the base 2 to conduct a stabilizing process on the fixed support frame 502, realizes the positioning of the mixing hopper 5, and enables the mixing hopper 5 to be disassembled and assembled. And the movable support frame 303 is detachably connected to the base 2, so that the installation position of the movable support frame 303 is adjustable. A mixing material discharge port 501 is opened at the bottom of the mixing hopper 5, and a discharge conveying belt 6 is installed below the mixing hopper 5. A discharge guiding cover 7 is sleeved and tightly installed at the mixing material discharge port 501 of the mixing hopper 5, and the length of the discharge guiding cover 7 is less than the width of the discharge conveying belt 6. A material control hole 701 is opened on one side of the discharge guiding cover 7 in the conveying direction of the discharge conveying belt 6, and a scraping flap 702 is arranged at the upper part of the discharge guiding cover 7 above the material control hole 701. This structure enables the mixing material discharged from the mixing hopper 5 to fall onto the discharge conveying belt 6 through the discharge guiding cover 7. The discharge conveying belt 6 adopts an existing concave conveying mechanism, and the conveying surface of the belt is bent into a concave structure by an inclined roller to avoid the leakage of powder materials. By arranging the material control hole 701 and the scraping flap 702 on the discharge guiding cover 7, the leakage of the mixing material from the discharge conveying belt 6 can be avoided, preventing the influence on the proportioning of the raw materials. The lower end of the mixing hopper 5 is connected to the fixed support frame 502, and positioning seats 4 are evenly and spacedly clamped at the upper end of the mixing hopper 5. And a clamping seat 401 which is clamped and matched with the screw weighing conveyor 302 is arranged above the positioning seats 4. And a hinge member 402 penetrates between the positioning seats 4 and the clamping seat 401, so that the raw material storage hopper 3 is positioned relative to the mixing hopper 5 through the positioning seats 4. The positioning seat 4 is of a U-shaped structure, and the outer part of the positioning seat 4 is fastened to the mixing hopper 5 through a through bolt.This structure allows the positioning seat 4 to adjust its position relative to the mixing hopper 5 and perform positioning and fixing. The raw material storage hopper 3 is fixed relative to the positioning seat 4 by clamping the spiral weighing conveyor 302 to the clamping seat 401. The hinge 402 enables the angle adjustment between the spiral weighing conveyor 302 and the positioning seat 4, facilitating the installation of the raw material storage hopper 3. At the same time, when adjusting the layout of the position of the raw material storage hopper 3, the raw material storage hopper 3 can be adjusted relative to the mixing hopper 5 through the positioning seat 4.

[0019] Working principle: When using this automatic weighing device for the raw materials of the environmental protection concrete formula, first, according to the formula of the environmental protection concrete, the number of raw material storage hoppers 3 is made consistent with the number of raw materials. The raw material storage hopper 3 is fixed on the base 2 through the movable support frame 303. The spiral weighing conveyor 302 is fixed on the positioning seat 4 through the clamping seat 401. According to the rotatable treatment of the clamping seat 401 by the hinge 402, the installation angle of the spiral weighing conveyor 302 is adapted to reduce the generation of installation errors. When the main body 1 of the automatic weighing device is working, various raw materials are introduced into the raw material storage hopper 3. The spiral weighing conveyor 302 is started, and the raw materials are respectively conveyed to the mixing hopper 5 through the raw material discharge port 301. During the process of conveying the raw materials, weighing is carried out by the sensors arranged on the spiral weighing conveyor 302, and the start and stop control is carried out by the existing control system for the spiral weighing conveyor 302 to perform automatic proportioning and weighing of the raw materials. The raw materials falling into the mixing hopper 5 fall from the mixing material discharge port 501 onto the discharge conveying belt 6. During the process of the discharge conveying belt 6 conveying the raw materials, the discharge guiding cover 7 restricts the discharge amount through the material control hole 701, and the scraping flap 702 levels the upper end surface of the raw materials, reducing the leakage during the raw material conveying and minimizing the influence on the accuracy of the weighing proportioning. The fixed support frame 502 is used for the basic positioning treatment of the main body 1 of the automatic weighing device, thus completing a series of operations.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
