Description

Technical Field

[0001] The invention patent relates to the technical field of transportation equipment, specifically, to an indoor rotating drop-type vibration mixing equipment for semi-rigid base materials of roads. Background Art

[0002] The current JTG / TF20-2015 "Technical Specifications for Highway Pavement Base Construction" and "Highway Inorganic Binder Test Procedure" do not provide a clear method for mixing the mixture in the inorganic binder mix design. So far, in indoor tests, whether it is the determination of the maximum dry density, the optimum water content or the molding of the unconfined compressive strength specimens, the mixture used is mixed manually. For freshly mixed cement-based materials, the soil is in a sticky-plastic state and belongs to the Bingham body. The bonding force between the surfaces of the components of the mixture makes it particularly difficult to mix it completely, especially the uniformity of the dispersion of water and cement cannot be guaranteed. In actual production, vibration mixing equipment has been widely used. The use of vibration mixing can improve the uniformity of the distribution of cement and water between aggregate particles and reduce the defects caused by mixing.

[0003] In the prior art, a Chinese patent with application number 2018107530172 discloses an indoor rotary drop-type vibration mixing device for semi-rigid base materials of roads, which belongs to the technical field of transportation equipment. The equipment includes an equipment outer frame, a barrel, an electromagnetic vibrating sheet, a rotating motor, a carbon brush and a control box; the barrel is obliquely installed on the crossbeam at the upper end of the equipment outer frame, the rotating motor and the control box are both installed on the equipment outer frame, the output end of the rotating motor drives the crossbeam at the upper end of the equipment outer frame to rotate through a transmission device, the control box is used to control the start and stop of the rotating motor, the electromagnetic vibrating sheet is two, pasted on two opposite sides of the barrel, the carbon brush supplies power to the two electromagnetic vibrating sheets, and the carbon brush is powered by the control box.

[0004] The above technical solution can increase the speed of uniform mixing of coarse and fine aggregates. However, in the above technical solution, the barrel is fixed on the rotating shaft at an angle. In actual use, the grain size and ratio of coarse and fine aggregates are adjusted according to the needs and characteristics of the road. The barrel with a fixed angle cannot be applied to coarse and fine aggregates with different grain sizes and ratios, and it is difficult to act on all materials. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The implementation of the present invention is described in detail below in conjunction with preferred embodiments.
