Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 As shown, it is a schematic diagram of the overall structure of the present invention, a fully automatic crushing system for blasting large blocks, including a distance measuring system 3, a control system 2 and a crushing device 1, wherein the crushing device includes a crushing drill bit 4, Telescopic arm 5 and fixed platform 8; the telescopic arm is installed on the fixed platform and drives the drill bit to move in three-dimensional space;
[0021] The ranging system is installed at the front end of the telescopic arm 5 of the crushing device, and the control system controls the crushing device to perform crushing operations based on the ranging signal fed back by the ranging system.
[0022] The signal transmission direction of the ranging system is perpendicular to the horizontal ground.
[0023] The ranging system includ...

The invention discloses a full-automatic breaking system and automatic exploding method for exploding a large block. The full-automatic breaking system comprises a distance measuring system 3, a control system 2 and a breaking device 1. The breaking device comprises a breaking drill bit 4, a retractable arm 5 and a fixing platform 8. The retractable arm is installed on the fixing platform and drives the drill bit to move in three-dimensional space. The distance measuring system is installed at the front end of the retractable arm of the breaking device. The control system controls the breaking device to execute the breaking operation according to distance measuring signals fed back by the distance measuring system. According to the full-automatic breaking system, the distance measuring system is applied to the breaking system, and no-man control is achieved on the whole breaking system. The whole breaking system is simple in structure and easy to control, and the working efficiency is greatly improved. According to the automatic exploding method based on the breaking system, accurate breaking is achieved through judgment on the distance measuring signals, and the accuracy of breaking is greatly improved.
Description
technical field [0001] The invention relates to a fully automatic crushing system and an automatic blasting method for blasting large blocks. Background technique [0002] In the mining process, whether shallow hole blasting, deep hole blasting or chamber blasting is used, unqualified large blocks will be produced. It has always been a very difficult problem in mine production to deal with the remaining large pieces in mining blasting. Although relevant technical measures and means have been adopted at home and abroad, a variety of large-block crushing methods have been tested, such as energy-gathering cartridges, high-pressure pulsed water jets, jet technology, laser technology, high-energy electron beam technology, plasma, electric arc, microwave, and For methods such as thermonuclear blasting, relatively speaking, the methods with relatively mature application and simple technology mainly include blasting method and mechanical fragmentation method. But there are the fol...
