DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

Please refer to Figures 1-3. The utility model provides a technical solution: a concrete mixing device, including a mixing box 1 and a top plate 4, the top outer wall of the mixing box 1 is sleeved with the top plate 4, and the central axis of the mixing box 1 is vertically provided with a transmission shaft 2, and the outside of the transmission shaft 2 is staggered with stirring blades 3, arc plates 401 are provided on both sides of the top of the top plate 4, and the arc plate 401 is provided with a side plate 402 near the top wall of the transmission shaft 2, the inner side of the arc plate 401 is penetrated and installed with a water outlet pipe 6, and the water inlet end of the water outlet pipe 6 is connected to a water supply pump 5; the inner wall of the mixing box 1 is provided with a box wall 104, and the bottom of the mixing box 1 is provided with a discharge slot 1 01, a discharge baffle 102 is installed on the shaft at the discharge slot 101, and an auxiliary baffle 103 is installed on the inner side of the discharge baffle 102; the outer wall of the transmission shaft 2 and the upper and lower ends of the stirring blade 3 are respectively installed with shaft sleeve plates 201; the stirring blade 3 is distributed in an arc shape as a whole, and the outer wall of the stirring blade 3 and the box wall 104 are matched in size; the auxiliary baffle 103 is made of soft plastic material; the bottom of the mixing box 1 is provided with supporting feet 7; the bottom shaft end of the transmission shaft 2 is provided with a driving motor 8, and the driving motor 8 is installed in the middle of the bottom wall of the mixing box 1; a detachable structure is formed between the mixing box 1 and the top plate 4, and the sizes of the mixing box 1 and the top plate 4 are matched with each other;

The arc-shaped stirring blades 3 are used, and their staggered distribution ensures that the raw materials of the inner concrete are fully stirred; the forward rotation of the stirring blades 3 drives the concrete on the inner wall to gather and disperse outward, so that the concrete is mixed more fully;

The stirring blade 3 cooperates with the auxiliary baffle 103 at the bottom. When rotating clockwise, the outer arc surface of the auxiliary baffle 103 is squeezed, thereby driving the discharge baffle 102, so that the discharge baffle 102 fits the mixing box 1 more closely, ensuring the relative sealing of the entire device;

When the discharge baffle 102 is opened, the counterclockwise rotation of the stirring blade 3 will push the auxiliary baffle 103, causing the discharge baffle 102 to expand outward, thereby avoiding blockage during discharge and improving discharge efficiency;

A large-diameter feed channel is used to ensure the portability of the mixing box 1 when feeding. The arc plate 401 at the top can effectively avoid splashing when feeding. In addition, the arc plate 401 can protect the water inlet to prevent blockage at the water inlet and extend the service life of the water inlet end.

Working principle: For this type of concrete mixing device, materials are first fed into the mixing box 1 through the discharge slot 101 on the top of the mixing box 1, and water is transported to the mixing box 1 through the water outlet pipe 6 through the water supply pump 5 on the top. At the same time, the driving motor 8 is controlled to start to drive the transmission shaft 2 to rotate clockwise, causing the stirring blades 3 to rotate forward to drive the concrete on the inner wall to gather and disperse outward. The staggered stirring blades 3 make the concrete mixing more fully. At this time, the stirring blades 3 at the bottom will squeeze the outer arc surface of the auxiliary baffle 103 when rotating, thereby driving the discharge baffle 102, so that the discharge baffle 102 fits the mixing box 1 more closely, and better avoids leakage;

When unloading is required, the unloading baffle 102 is opened, and then the counterclockwise rotation of the stirring blade 3 is utilized to continuously throw the concrete outward. In addition, the stirring blade 3 can also push the auxiliary baffle 103, causing the unloading baffle 102 to expand outward to avoid blockage during unloading.

The above description is only a specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be thought of by any technician familiar with the field within the technical scope disclosed by the utility model without creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
