[0022] 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.

[0023] Please see Figures 1-3 In this embodiment of the present invention, a feeding device for a concrete mixer includes a mixing box 1, a mixing rod 2 rotatably mounted on the shaft of the inner cavity of the mixing box 1 for mixing materials, a drive motor connected to the shaft of the mixing rod 2 is installed at the bottom of the mixing box 1, and a feeding unit 3 disposed on the outer wall of the mixing box 1 for intermittent feeding.

[0024] The feeding unit 3 includes a feeding unit and a transmission unit;

[0025] The drive unit provides power for the movement of the unloading unit;

[0026] The feeding unit is used to quantitatively add stone to the mixing tank 1;

[0027] The unloading unit includes an unloading box 301, a pusher plate 302, an unloading trough plate 303, and a movable plate 304;

[0028] The feeding box 301 is fixed to the outer wall of the mixing box 1 by a mounting bracket. The inner cavity of the feeding box 301 is symmetrically and slidably equipped with a pusher plate 302 and a movable plate 304. The pusher plate 302 is distributed in a "Z" shape in the inner cavity of the feeding box 301, and the movable plate 304 is distributed in a "C" shape in the inner cavity of the feeding box 301. The bottom horizontal plate of the movable plate 304 coincides with the bottom feeding port of the feeding box 301. A feeding trough plate 303 for material to enter the inner cavity of the feeding box 301 is fixed between the pusher plate 302 and the top horizontal plate of the movable plate 304.

[0029] The transmission unit includes a rack 305, a gear 306, a servo motor 307, a positioning rod 308, and a spring 309;

[0030] The rack 305 is fixed to one side of the outer wall of the feeding trough plate 303. The gear 306 is rotatably installed on the outer wall of the feeding box 301 and meshes with the outer wall tooth block of the rack 305. The servo motor 307 is installed on the outer wall of the feeding box 301 through the support frame, and the output top of the servo motor 307 is connected to the shaft of the gear 306 through the shaft.

[0031] The positioning rod 308 is fixed to the outer wall of the movable plate 304 and extends through the feeding box 301 to the outside of the feeding box 301. The spring 309 is wrapped around the outer wall of the positioning rod 308, and the two ends of the spring 309 are respectively engaged in the inner cavity of the feeding box 301 and the outer wall of the movable plate 304.

[0032] In this embodiment: the stones to be added are fed into the inner cavity of the feeding box 301 through the feeding trough plate 303. The stones will be between the pusher plate 302 and the movable plate 304. Then, by starting the servo motor 307, the gear 306 connected to the output end of the servo motor 307 will rotate. The rotating gear 306 will provide an axial thrust to the rack 305 meshing with its outer wall, causing the rack 305 to drive the pusher plate 302, the feeding trough plate 303, and the movable plate 304 to move axially synchronously. The movable plate 304 will drive the positioning rod 308 to move axially along the inner cavity of the feeding box 301. When spring 309 is applied with compressive force, the bottom horizontal plate of movable plate 304 moves out of the bottom discharge port of discharge box 301. At the same time, the vertical plate of pusher plate 302 applies a pushing force to the stone between pusher plate 302 and movable plate 304, causing the stone to move out through the discharge port at the bottom of discharge box 301. After feeding is completed, gear 306 no longer contacts rack 305, and movable plate 304 will also push pusher plate 302, discharge trough plate 303 and movable plate 304 to reset under the elastic force of spring 309, thus waiting for the next feeding, achieving the purpose of intermittent feeding.

[0033] Please refer to this carefully. Figures 1-3 The outer wall teeth of gear 306 are distributed at 180 degrees on the outer wall of gear 306, and the vertical rod of push plate 302 is inclined on the side near movable plate 304.

[0034] In this embodiment: With this structure, after the gear 306 rotates and pushes the rack 305 axially to a certain distance, the gear 306 no longer contacts the rack 305, so that the rack 305 is reset under the action of the spring 309. When the pusher plate 302 moves with the movement of the feed trough plate 303, the feed port at the bottom of the feed box 301 opens, and the inclined surface of the vertical plate of the pusher plate 302 provides guidance for the feeding of the stone.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
