Advance digging hydraulic cleaving machine for mine blasting

Abstract

The invention provides a pre-excavation hydraulic splitting machine for mine blasting, which includes a main body shell, a No. 1 protective baffle and a No. 2 protective baffle; a magnetic baffle clamp is fixedly arranged on the outside of the bottom of the main body shell seat. The setting of the protective baffle is conducive to the convenience of use. When using this device, the No. 1 protective baffle is installed on the other side of the magnetic baffle holder, and the protrusion of the No. In the groove on one side of the baffle, the hemispherical protrusions on the top and bottom of the bump on the No. The connection of the protective baffle is more firm, and the small gravel and fine sand that are split from the cracks of the rock will be blocked by the No. 1 protective baffle and the No. 2 protective baffle when splitting, so as to avoid causing harm to the body of the staff, and The working conditions can be observed through the tempered glass window on the protective baffle, which is more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of stone mining, and in particular relates to a pre-excavation hydraulic splitter for mine blasting. Background technique [0002] There are many stone mines in our country, but there are not many mines with regular construction and mechanized mining. Most of the mines still use the original method of pond mouth mining, which has an extremely low rate of waste. According to the data, the block rate of stone mining by Tangkou blasting method is generally between 4% and 6%, and the mining area with a good degree of mechanization will not exceed 10%, and the remaining 90% of the resources are used in the mining process. turned into rubble. As we all know, stone is a non-renewable resource in natural resources, and the more it is mined, the less it will be, so limited stone resources must be cherished. With the improvement of technical conditions, hydraulic splitters are now being used in the high-end market. ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a pre-excavation hydraulic splitter for mine blasting, to solve the need to insert the splitting block at the bottom directly into the soil when the existing hydraulic splitter is in use, and then A staff member supports the splitter to work. Sometimes small gravel and fine sand will burst out of the rock cracks during the splitting process. If it falls directly into the staff's face or eyes, it may cause serious damage to the staff. If the staff wear protective glasses, it will make the staff more uncomfortable, and it will be more inconvenient to operate.
