[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] like Figures 1 to 4 As shown, this utility model provides a concrete admixture feeding device, including a support frame 1 and a storage box 2 installed on the right side of the support frame 1. The storage box 2 is used to store concrete admixtures. Two drive motors 3 are symmetrically installed on the front outer wall of the storage box 2, and the output end of the drive motor 3 passes through the front side of the storage box 2 and is connected to a crushing roller (not shown in the figure). The two drive motors 3 can drive the two crushing rollers to rotate in opposite directions to crush the lumped concrete admixtures. A support frame 4 is horizontally fixedly inserted into the lower inner part of the storage box 2. A connecting frame 5 is provided above the support frame 4, and a screen plate 6 is nested at the bottom inner side of the connecting frame 5. The screen plate 6 can screen the concrete admixtures, and concrete admixtures with smaller diameters will fall through the screen holes. Two vibration motors 7 are symmetrically installed at the bottom of the connecting frame 5 via motor mounts. The existing principle can be used to drive the connecting frame 5 and the screen plate 6 to vibrate continuously. Two rows of insert rods 8 are connected side by side at the bottom of the connecting frame 5 by screws. The insert rods 8 are movably inserted into the corresponding side of the connecting frame 5. When the connecting frame 5 vibrates, multiple insert rods 8 will move relative to the support frame 4. The spring 9 will buffer the connecting frame 5, thereby ensuring that the connecting frame 5 can vibrate stably. The side wall of the insert rod 8 is fitted with a spring 9, and the spring 9 is connected between the corresponding side of the connecting frame 5 and the support frame 4. A feeding pipe 10 with a control valve (not shown in the figure) is inserted into the bottom right side of the storage box 2. The concrete admixture can be fed through the feeding pipe 10 by opening the control valve.

[0023] Specifically, a top cover 11 is hinged to the rear side of the top of the storage bin 2. The concrete admixture can be put into the inside of the storage bin 2 by opening the top cover 11. A latch is installed between the top cover 11 and the corresponding side of the storage bin 2. The top cover 11 can be opened by opening the latch.

[0024] Furthermore, a hydraulic rod 12 is installed at the top center of the support frame 1, and the output end of the hydraulic rod 12 is connected to the bottom center of the storage box 2 by bolts. The hydraulic rod 12 can drive the storage box 2 to lift and lower.

[0025] Furthermore, a fixing seat 14 is fixedly sleeved on the side wall of the hydraulic rod 12, and the fixing seat 14 is connected to the top of the support frame 1 by multiple screws, which increases the stability of the hydraulic rod 12 during operation.

[0026] It is worth noting that the right side wall of the support frame 1 has two parallel sliding grooves 13, and the left outer wall of the storage box 2 has two sets of sliders (not shown in the figure) connected side by side. The sliders slide into the corresponding sliding grooves 13. The sliding of the two sets of sliders in the corresponding sliding grooves 13 can increase the stability of the lifting process of the storage box 2.

[0027] It is worth noting that each of the four corners of the bottom of the support frame 1 is equipped with a movable wheel 15 with a braking function. The device can be moved by the movable wheel 15. Two handles 16 are connected side by side on the left side wall of the support frame 1 by screws. The handles 16 facilitate the movement of the device.

[0028] It is worth mentioning that a storage box 17 is connected to the lower left side wall of the support frame 1 by multiple screws. The storage box 17 can be used to store maintenance tools for easy access. A cover plate is hinged to the top side of the storage box 17, and the maintenance tools can be accessed by opening the cover plate.

[0029] Among them, the vibration motor 7 and the hydraulic rod 12 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: First, open the top cover 11 and put the concrete admixture into the inner side of the storage box 2. The lumpy concrete admixture will be crushed by two continuously rotating crushing rollers. The crushed admixture will fall into the inner side of the connecting frame 5. The connecting frame 5 and the screen plate 6 will vibrate continuously under the action of the vibrating motor 7 and the spring 9. The vibrating screen plate 6 can screen out the admixture with small diameter. When the screened admixture with small diameter is discharged through the feeding pipe 10, it will not block the feeding pipe 10. The relative height of the feeding pipe 10 can be adjusted by driving the storage box 2 to rise and fall by the hydraulic rod 12.
