Problems solved by technology

In this way, on the one hand, the labor cost and labor intensity are greatly increased, and the labor efficiency is low. On the other hand, it is not easy to find such a large number of blocking materials around the blast holes.
At the same time, due to the use of drill cuttings with a relatively low density, the friction between the drill cuttings with the same packing length...

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] like figure 1 Shown, the present invention has motor vehicle chassis 6, and the front end of this motor vehicle chassis 6 is cab 5, and the specific structure of motor vehicle chassis 6 is identical with prior art, does not repeat them here. On the platform of the motor vehicle chassis 6, a graded batching bin 1 is arranged. The graded batching bin 1 is a funnel-shaped structure with a large top and a small bottom, and the upper end is open. The volume of the graded batching bin 1 is 2m 3 As mentioned above, the graded batching bin 1 is used to accommodate the graded batching 2, and the particle size of the graded batching 2 is 1 cm to 3 cm.

[0014] like figure 1 As shown, the discharge port 3 at the lower end of the grading bin 1 is connected to the feed port 10 of the first screw conveyor 11 through the flange 4, and the blade of the first screw c...

Abstract

The invention discloses a mechanical blast hole plugging device. A graded material distribution bin is arranged on a platform of a motor vehicle chassis; a discharge opening in the lower end of the graded material distribution bin is connected with a feed opening of a first spiral conveyor through a flange; a vane of the first spiral conveyor is connected with the output end of a speed reducer through a rotating bearing; and the input end of the speed reducer is connected with an output shaft of a motor. A discharging opening of the first spiral conveyor penetrates through the platform of the motor vehicle chassis, and is connected with a feed opening of a second spiral conveyor through a rotating shaft. According to the mechanical blast hole plugging device, graded distributed materials are produced by directly crushing soil sediments at a site blasting stripping portion on the mechanical plugging device; and open blasting adopts a mechanical plugging mode, so that the labor intensity is effectively lowered, the production efficiency is improved, and the source problem of plugging materials is fundamentally solved. The plugging materials adopt graded distributed materials with relatively high density, so that the plugging quality is improved, the utilization rate of blast holes is improved, and the drilling cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of blasting, and in particular relates to a mechanical plugging device for blastholes. Background technique [0002] With the development of on-site mixed blasting technology and delayed initiation technology, the scale of single blasting in open-pit mines is also increasing, and some emerging blasting technologies, such as large-aperture high-step blasting and pre-charged blasting, have gradually begun to be used in the blasting industry. It is highly praised in the platooning industry. After adopting these technologies, the amount of explosives in a single shot can be as high as hundreds or even thousands of tons, and labor productivity has been greatly improved. However, for these large-scale blastings, the manual filling method is still mainly used in the blasthole plugging at present. The filling material is mainly the drilling cuttings around the blasthole. Taking a blasthole with a diameter of 250mm a...
