[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0019] Please refer to Figs. 1-2 The present application provides a technical scheme: a concrete mixing station powder feeding mechanism, which comprises a storage bin 1 and a material guide frame 2. The storage bin 1 is fixedly installed above the material guide frame 2 through a support. The bottom of the storage bin 1 is provided with a discharge pipe. The material guide frame 2 is provided with a material guide plate 3 matched with the discharge pipe. The material guide plate 3 can be provided with a material conveying belt on one side to facilitate material conveying. The material guide frame 2 is further provided with a buffer component used in cooperation with the material guide plate 3. The buffer component comprises a fixed plate 4 arranged between the material guide frames 2. The fixed plate 4 is provided with a spring 5 between the material guide plate 3.

[0020] The buffer component further comprises a first guide rod 6 fixedly arranged on the side wall of the material guide plate 3. The side wall of the material guide frame 2 is provided with a guide groove 7 matched with the guide rod 6.

[0021] The material guide frame 2 is in a Z-shaped structure. The first guide rod 6 is further connected with a second guide rod 8. The cross section of the first guide rod 6 is square. The cross section of the second guide rod 8 is circular. The diameter of the second guide rod 8 is the same as the side length of the first guide rod 6.

[0022] And the first guide rod 6 distance material guide frame 2 lower end gap, so when the storage bin 1 is discharged, the material falling on the guide plate 3, so that the guide plate 3 is under the gravity of the decline, due to the first guide rod 6 and guide slot 7 between the limit, will make the guide plate 3 horizontal decline, until the decline to the material guide frame 2 horizontal section location, the first guide rod 6 and guide slot 7 at this time is disengaged, and the second guide rod 8 and guide slot 7 cooperation, so that the guide plate 3 rotation, convenient guide plate 3 surface of the powder fall, and the guide plate 3 in the process of decline will extrude spring 5, so that the spring 5 is compressed, when the powder fall, the guide plate 3 at this time will be under the action of spring 5, fast reset, in order to ensure that the guide plate 3 each time in the same direction of rotation, can be set in its below another direction limit rod, so as to limit its another direction, ensure that the direction of rotation each time is same.

[0023] The upper end of the guide plate 3 is also provided with two groups of ejector rods 9, which are matched with the bottom of the storage bin 1. In this way, when the powder on the guide plate 3 is poured, the ejector rods 9 will hit the storage bin 1 in the rebound process of the guide plate 3, thereby producing a knocking effect on the storage bin 1, preventing the powder from being blocked during the discharging process.

[0024] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
