Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a concrete mixing device. Background Art

[0002] Construction equipment mainly includes elevators, cranes, concrete mixers, concrete spraying and pouring machines, etc. The novel concrete mixing device mentioned in this application is mainly used for mixing and pouring concrete. Concrete is a building material made by mixing cement, sand, gravel, water and an appropriate amount of admixtures in a certain proportion. It is a common and widely used structural material for building buildings, roads, bridges and mine construction, etc.

[0003] Due to the different uses, pouring methods and pouring positions of concrete, the usage methods of concrete are also different. However, the existing concrete pouring devices have relatively single functions and usually require the cooperation of multiple devices such as loaders, grouting pumps and shotcreting machines for use. This is not only time-consuming and laborious for workers, but also requires a lot of labor from mining workers, especially when loading materials, resulting in a low scope of application. Although the existing concrete pouring devices have the function of mixing concrete, most of them rely on the single-direction rotation of mixing blades for mixing, which not only makes the mixing efficiency of concrete low, but also easily leads to insufficient mixing of concrete, so that the raw materials in the concrete are not evenly mixed, affecting the structural strength of the concrete in the later stage. In addition, the current concrete pouring devices are not convenient when loading materials. Therefore, this application provides a concrete mixing device to solve the above technical problems. Content of the Utility Model

[0004] In order to solve the above existing technical problems, the utility model provides a concrete mixing device, which solves the problems of relatively single functions of the existing concrete pouring devices, insufficient mixing of concrete and inconvenient loading of materials.

[0005] The technical solution adopted in the embodiment of the utility model is: a concrete mixing device that can be connected to a vehicle frame and a mixing tank, characterized in that it includes a rotating cylinder rotatably connected to the mixing tank, a rotating rod rotatably connected to the rotating cylinder, and an adjusting component connecting the rotating cylinder and the rotating rod. The adjusting component is connected to the vehicle frame. The rotating cylinder is provided with a first mixing blade, and the rotating rod is provided with a second mixing blade. Driving the rotating rod can realize the two-way mixing of the raw materials in the mixing tank by the first mixing blade and the second mixing blade.

[0006] Further, the rotating cylinder is of a hollow structure, with both ends thereof located inside and outside the mixing tank respectively. The rotating rod is inserted into the end of the rotating cylinder located outside the mixing tank and is rotatably connected thereto.

[0007] Further, the end of the rotating rod away from the rotating cylinder is connected to a belt through a first pulley.

[0008] Further, the adjusting assembly includes a first bevel gear provided on the rotating cylinder, a second bevel gear provided on the rotating rod, and a third bevel gear that meshes with both the first bevel gear and the second bevel gear. The third bevel gear is connected to the vehicle frame through a support column.

[0009] Further, the support column is rotatably connected to a support rod through a support disc, and the end of the support rod away from the support disc is connected to the vehicle frame.

[0010] Further, it further includes a feeding mechanism. The feeding mechanism includes a feeding cylinder provided with a discharge pipe and a feeding trough, a rotating rod rotatably connected to the inner wall of the feeding cylinder, and conveying blades provided on the outer side of the rotating rod. Driving the rotating rod enables the raw materials to enter the mixing tank after passing through the feeding trough, the feeding cylinder, and the discharge pipe.

[0011] Further, the mixing tank is provided with a feeding hopper, and the discharge pipe faces the feeding hopper.

[0012] Further, fixing columns are symmetrically provided on the outer side of the feeding cylinder, and the ends of the fixing columns away from the feeding cylinder are connected to auxiliary wheels through first reinforcing plates.

[0013] Further, the first reinforcing plate is connected to the vehicle frame through a second reinforcing plate.

[0014] Further, a spraying machine body is provided on the vehicle frame. The input end of the spraying machine body is communicated with the mixing tank through a conduit, and its output end is provided with a spraying pipe. The spraying pipe is connected to the vehicle frame through a placing rod.

[0015] The advantages and positive effects of the present utility model are:

[0016] First, by providing a mixing tank and a stirring mechanism, the device can perform two-way stirring on the concrete in the mixing tank, thereby effectively avoiding the situation of low stirring efficiency caused by the one-way rotation of most stirring blades in the prior art to stir the concrete. This not only further ensures more sufficient stirring of the concrete but also enables the raw materials constituting the concrete to be mixed more evenly, further ensuring the structural strength of the concrete in the later stage.

[0017] Second, by providing a mixing tank, a feeding mechanism and a feeding hopper, the device can be conveniently fed, thus effectively avoiding the situation that people need to rely on a loader for feeding due to the lack of a feeding function, making it more time-saving and labor-saving for the staff to use.

[0018] Third, through the coordinated setting of the mixing tank, the stirring mechanism, the feeding mechanism, the shotcreting machine body and the grouting machine, the applicable range of the device can be further improved, thus effectively avoiding the situation that in the prior art, due to the relatively single function, multiple devices need to be coordinated for use by the staff. This not only further improves the applicable range of the device, but also further ensures the production efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Working principle: When using this device, the staff first move the device beside the concrete raw materials, and then start the first motor 403 to drive the rotation of the rotating rod 402. With the rotation of the rotating rod 402, the rotation of the conveying blade 404 can be driven. Under the action of the rotation of the conveying blade 404, the concrete raw materials can be pumped through the feeding chute 406 into the feeding cylinder 401 and injected into the mixing tank 2 through the discharge pipe 405, so as to realize the automatic feeding of this device.

And with the rotation of the second bevel gear 304, the rotation of the third bevel gear 309 can be driven. Through the rotation of the third bevel gear 309, the first bevel gear 303 can be driven to rotate. With the rotation of the first bevel gear 303, the rotation of the rotating cylinder 301 can be driven. With the rotation of the rotating cylinder 301, the rotation of the first stirring blade 306 can be driven, thereby realizing the bidirectional rotation of the first stirring blade 306 and the second stirring blade 307, so as to realize the bidirectional stirring of the concrete in the mixing tank 2. This not only further ensures more sufficient stirring of the concrete, but also enables the raw materials constituting the concrete to be mixed more evenly, further ensuring the structural strength of the concrete in the later stage. After the stirring is completed, the staff can move the device to the designated position and start the spraying machine body 9 or the grouting machine 11 to carry out spraying or grouting operations under the action of the spraying pipe 10 or the grouting pipe 12, thus effectively avoiding the situation that in the prior art, due to the relatively single function, multiple devices need to be coordinated by the staff when using. This not only further improves the applicable range of this device, but also further ensures the production efficiency of this device.
