Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] like Figures 1 to 3As shown, the utility model provides a quantitative raw material discharge hopper for concrete production, including a bottom plate 1, the lower end of the bottom plate 1 is provided with four brake wheels 11, and the four brake wheels 11 are distributed in a mirror image, both sides of the upper end of the bottom plate 1 are fixed with limit frames 2, a discharge pipe 7 is fixedly provided between the two limit frames 2, a movable plate 21 is slidably provided between the two limit frames 2, a movable bucket 22 is embedded in the upper end of the movable plate 21, a cover plate 23 is rotatably provided on one side of the lower end of the movable bucket 22, a limit plate 24 is fixedly provided on the upper end of the bottom plate 1, an arc block 5 is provided above the limit frame 2, and a storage barrel 6 is provided on the upper ends of the two arc blocks 5, a vertical plate 3 is fixedly provided at one end of the bottom plate 1, a discharge hopper 4 is fixedly provided on one side of the lower end of the bottom plate 1, and the bottom plate 1 is used as a supporting connection carrier, which is connected by the brake wheel 11. The lower hopper structure can be easily moved to the required position, and the moving plate 21 can slide between the limiting frames 2, so that the movement of the moving bucket 22 can be realized. The moving bucket 22 is the main body of the lower hopper structure. When the moving bucket 22 moves to the bottom of the discharge pipe 7, the concrete raw materials in the storage barrel 6 enter the moving bucket 22 through the discharge pipe 7. At this time, the cover plate 23 is supported by the limiting plate 24. When the mobile bucket 22 is full of raw materials, the moving plate 21 moves to drive the mobile bucket 22 to move. At this time, the moving plate 21 blocks the lower end of the discharge pipe 7. At the same time, as the cover plate 23 is no longer in contact with the limiting plate 24, the cover plate 23 is opened, and a certain amount of raw materials are discharged through the discharge hopper 4. The overall structural design is simple, practical and reliable, and the concrete raw materials can be continuously and quantitatively discharged to improve the subsequent concrete processing quality.

[0023] See also Figure 2 A push plate 25 is fixedly provided at one end of the movable plate 21, and a servo cylinder 31 is fixedly provided at one end of the vertical plate 3. The output end of the servo cylinder 31 passes through the vertical plate 3 and is fixedly provided with a connecting column 32. One end of the connecting column 32 is fixedly connected to the push plate 25. The servo cylinder 31 serves as a driving source. When discharging is required, the servo cylinder 31 is started to drive the push plate 25 to move through the connecting column 32. The servo cylinder 31 is set to pause for a while after outputting once at the output end, so that the discharging of the discharging pipe 7 can be coordinated, thereby realizing stable quantitative discharging.

[0024] See also Figure 3 A connecting block 231 is fixedly provided at one end of the cover plate 23 of the present application, two support rods 232 are fixedly provided on the lower side of the outer surface of the mobile bucket 22, and the two ends of the connecting block 231 are rotatably connected to the two support rods 232 respectively. Through the rotational cooperation of the support rods 232 and the connecting block 231, the cover plate 23 can be rotated on one side of the lower end of the mobile bucket 22.

[0025] As another embodiment of the present application, Figure 4The support block 51 is fixedly provided with a support block 51 at the upper end of the limiting frame 2 of the present application, and a screw rod 52 is rotatably provided at the lower end of the arc block 5. A bearing is rotatably provided between the upper end of the screw rod 52 and the arc block 5, and the bearing can assist the rotation of the screw rod 52 and the arc block 5, thereby improving the stability of the lifting and lowering adjustment of the arc block 5. The lower end of the screw rod 52 passes through the support block 51 and is fixedly provided with a knob 53. Two telescopic rods 54 are fixedly provided between the arc block 5 and the corresponding support block 51. The material storage barrel 6 is placed between the two arc blocks 5. The height of the arc block 5 is adjustable. Specifically, the knob 53 is turned to rotate the screw rod 52. When the screw rod 52 rotates, it moves up and down on the support block 51, thereby driving the arc block 5 to move up and down. The telescopic rod 54 limits the moving position of the arc block 5 to prevent the arc block 5 from rotating when it moves up and down. The arc support structure that is easy to adjust makes it possible to place material storage structures of various sizes, which can all be used for quantitative unloading, thereby improving the versatility of the unloading hopper.

[0026] The working principle of the present application is as follows: the bottom plate 1 is used as a supporting and connecting carrier, and the lower hopper structure can be conveniently moved to the required position through the brake wheel 11, and the movable plate 21 can slide between the limiting frames 2, so that the movement of the movable bucket 22 can be realized. The movable bucket 22 is the main body of the lower hopper structure. When the movable bucket 22 moves to the bottom of the discharge pipe 7, the concrete raw materials in the storage barrel 6 enter the movable bucket 22 through the discharge pipe 7. At this time, the cover plate 23 is supported by the limiting plate 24. When the movable bucket 22 is full of raw materials, the movable plate 21 moves to drive the movable bucket 22 to move. At this time, the movable plate 21 blocks the lower end of the discharge pipe 7. At the same time, as the cover plate 23 is no longer in contact with the limiting plate 24, the cover plate 23 is opened, and a certain amount of raw materials are discharged through the discharge hopper 4. The overall structural design is simple, practical and reliable, and the concrete raw materials can be continuously and quantitatively discharged to improve the subsequent concrete processing quality.

[0027] The servo cylinder 31 is used as a driving source. When material is to be discharged, the servo cylinder 31 is started to drive the push plate 25 to move through the connecting column 32. The servo cylinder 31 is set to output once and pause for a while, so that the material can be discharged from the discharge pipe 7, thereby realizing stable quantitative material discharge.

[0028] Through the rotational cooperation of the support rod 232 and the connecting block 231, the cover plate 23 is rotated on one side of the lower end of the moving bucket 22;

[0029] The material storage barrel 6 is placed between the two arc blocks 5. The height of the arc block 5 is adjustable. Specifically, the knob 53 is turned to rotate the screw rod 52. When the screw rod 52 rotates, it moves up and down on the support block 51, thereby driving the arc block 5 to move up and down. The telescopic rod 54 limits the moving position of the arc block 5 to prevent the arc block 5 from rotating when it moves up and down. The easily adjustable arc support structure makes it possible to place material storage structures of various sizes, all of which can be used for quantitative unloading, thereby improving the versatility of the unloading hopper.
