Beneficial Effects

[0022] The present utility model provides a feeding port structure of a concrete mixer. Compared with the prior art, it has the following beneficial effects:

[0023] (1). The feeding port structure of this concrete mixer allows raw materials to be placed into the feeding frame from the receiving hopper.

After the concrete raw materials fall into the feeding frame and the discharge hopper, they are discharged into the interior of the mixer tank through the discharge pipe. When the concrete raw materials start to be fed, since dust will surge upward after the sand, gravel, and cement are fed, the feeding assembly can perform dust reduction treatment on it. The sprayed water mist avoids direct contact with the raw materials, preventing the material from adhering to the inner walls of the receiving hopper, the feeding frame, and the discharge hopper, and avoiding the waste and inconvenience in cleaning caused by the adhesion of the material.

[0024] (2). The feeding port structure of this concrete mixer drives the first gear and the rotating shaft to rotate through the working motor. The first gear drives the second gear meshing with it to rotate, and the rotating shaft drives the connecting rod and the stirring blade to rotate on the support plate to mix and stir the concrete raw materials inside the mixer tank. After the stirring is completed, the control valve is opened and the materials are discharged through the discharge pipe, enabling the concrete raw materials to be mixed and stirred, and can be stirred in different directions to make the mixing more sufficient.

[0036] In the embodiment of the present utility model, the purpose of this setting is that the setting of the stirring assembly 6 can fully mix the concrete raw materials inside the mixer tank body 1 evenly. At the same time, the rotating directions of the rotating shaft 64 in the middle and the rotating shafts 64 on the left and right sides are opposite, so as to drive the corresponding stirring blades 66 to rotate in different directions, which can improve the mixing uniformity of the raw materials inside the mixer tank body 1.

[0037] At the same time, the content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0038] During operation, first connect the liquid pump 513 and the drive motor 511 through an external power supply and a controller. When making concrete, place the raw materials from the material receiving hopper 54 into the inside of the feeding frame 51. When the sand, gravel and cement fall, it will cause the dust to surge upwards and overflow to the upper part of the material receiving hopper 54. Immediately start the liquid pump 513 and the drive motor 511 and pump water from the outside through the water inlet pipe 514, and inject it into the inside of the movable hose 57 through the delivery pipe 512, and then spray water mist upwards from the spray head 56 through the water outlet pipe 55. At the same time, the drive motor 511 drives the first bevel gear 58 on the right side to rotate. When the first bevel gear 58 on the right side rotates, it drives the second bevel gear 510 on the right side that meshes with it to rotate, and then drives the transmission shaft 59 and the second bevel gear 510 on the left side to rotate. The first bevel gear 58 on the left side that meshes with it is synchronously driven to rotate. Furthermore, the first bevel gears 58 on both the left and right sides drive the water outlet pipe 55 and the spray head 56 to start rotating left and right. The water mist sprayed by the spray head 56 can perform dust reduction on the surging dust, and can prevent the sprayed water mist from directly contacting the concrete raw materials, causing the raw materials to adhere to the inside of the material receiving hopper 54, the feeding frame 51, and the discharge hopper 52. When the concrete raw materials fall into the feeding frame 51 and the discharge hopper 52, they are discharged into the inside of the mixer tank body 1 through the discharge pipe 515. By starting the working motor 61 to drive the first gear 68 and the rotating shaft 64 to rotate, when the first gear 68 rotates, it drives the second gear 63 that meshes with it to rotate. Furthermore, the rotating shaft 64 starts to drive the connecting rod 65 and the stirring blade 66 to rotate on the support plate 67, and can mix and stir the concrete raw materials inside the mixer tank body 1. When the stirring is completed, open the control valve 3 and discharge through the discharge pipe 4.
