Embodiment Construction
[0019] Such as figure 1 , figure 2 , image 3 Shown: a dry powder quick-setting agent conveying device for a mine-used automatic feeding concrete jetting machine: it includes: a material box 6, a control valve assembly 5, a collection cavity assembly 3, a distributor assembly 4, and a discharge pipe assembly 2 , base 1 and motor reducer 9. The material box 6 is a funnel-type box, and the dry powder accelerator is put into the material box 6. The lower part of the material box 6 is a circular tube-shaped discharge pipe II6-2, and the lower end of the discharge pipe II6-2 has a flange IV6 -1, the flange IV6-1 is connected with the collection cavity assembly 3.
[0020] The control valve assembly 5 includes: a baffle plate 5-1, a round pipe II 5-2, a shaft II 5-3 and an adjustment handle 5-5. The baffle plate 5-1 is two semicircular flat plates, which are symmetrically fixed on both sides of the circular tube II 5-2, and the two semicircular flat plates form a circular flat ...

The invention discloses a dry powder accelerator conveying device for a mining automatic feeding concrete spraying machine, and relates to mine machinery. The dry powder accelerator conveying device consists of a material box, a control valve component, a material collection cavity component, a material divider component and a material discharging pipe component, wherein the control valve component is arranged on the lower part of the material box; a hand shank is adjusted to rotate a material stop plate, so that the flow of a dry powder accelerator is controlled; the material collection cavity is connected with the material box through a flange; the material divider is driven by a hydraulic motor speed reducer, so that high-pressure gas in the material discharging pipe component can be prevented from entering the material box; the upper part of the material discharging pipe component is connected with the material collection cavity through a flange; the lower part of the material discharging pipe is fixed on a base through a bracket; the base is arranged on a concrete spraying machine set stander; the material discharging pipe takes the high-pressure gas as a conveying medium; the high-pressure gas brings away the dry powder accelerator and conveys the dry powder accelerator to a nozzle of the concrete spraying machine through a pipeline; and the dry powder accelerator is mixed with concrete sprayed from the concrete spraying machine, and the mixture is sprayed to a rock wall. The whole device has a full-sealed structure; and injury of dust to an operator can be effectively avoided.
Description
technical field [0001] The invention relates to a mining machine, in particular to a dry powder quick-setting agent conveying device used on a mining automatic feeding concrete injection unit. Background technique [0002] At present, before coal mines use a shotcrete machine to carry out concrete spraying operations, the shotcrete machine must be placed according to the needs and possibilities of the construction site. The mine car transports the dry concrete to the job site, adds water and dry powder accelerator, and sends the finished concrete after mixing to the concrete sprayer, which sprays it onto the rock wall. Due to the narrow working site in the mine, the mine car is not necessarily close to the shotcrete machine, sometimes the two are far apart, and the concrete must be manually transported to the shotcrete machine, which is labor-intensive and low in efficiency. The applicant invented a "Mine Automatic Feeding Concrete Injection Unit", and has applied for natio...
