Description
Technical Field
[0001] The invention relates to the technical field of concrete feeding, and in particular to a uniform quantitative feeding device. Background Art
[0002] Concrete: It is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering. Nowadays, most of the usage methods are to place the concrete mixer directly above the steel membrane and the ground where it needs to be laid. The mixed concrete is directly applied to the surface of the construction object after being conveyed by a belt. It should be noted that:
[0003] Due to the viscosity of concrete itself and the presence of large particles, when the concrete is removed from the concrete mixing device along the conveyor belt, due to the working characteristics of the concrete mixer, the concrete is unevenly mixed, resulting in concrete with different viscosities showing different moving speeds under the concrete conveyor belt. Concrete with high viscosity falls slowly, and some concrete with high viscosity is easy to adhere to the surface of the conveyor belt; concrete with thin viscosity falls quickly, resulting in intermittent falling of the concrete, and the amount of concrete discharged is uncertain. There is a large difference between the amount of concrete dropped at a single time from the outlet end of the conveyor belt.

[0008] The whipping assembly comprises a second motor fixedly arranged on the outer side wall of the chassis and a second rotating shaft arranged in the chassis and having one end passing through the side wall of the chassis and connected to the output end of the second motor.

[0031] Furthermore, the number of the electric push rod 35 and the guide current limiting block 36 is two.
[0032] The mounting drum 34 is provided with a power source (not shown) for the electric push rod 35 .
[0033] The electric push rod 35 is a prior art, which is well known to those skilled in the art and can be easily implemented, and will not be elaborated here.
[0034] The whipping assembly 4 includes a second motor 41 fixed to the outer wall of the chassis 1 and a second rotating shaft 42 disposed in the chassis 1 and having one end passing through the side wall of the chassis 1 and connected to the output end of the second motor 41 .
[0035] Furthermore, the quantitative drum 3333 is the same length as the chassis 1.
