[0003] When the traditional roadheader is digging, it will convey the broken rock out of the tunnel at the same time, and when conveying the gravel, it needs to sweep the gravel onto the conveying device. The existing roadheader uses a scraper to scrape the gravel. The distance between the scraper and the scraper is fixed, and when the scraper rotates, it is easy to cause gravel to be stuck between the scraper and the scraper, so that rigid wear occurs between the scraper and the scraper, reducing the service life of the scraper , for which we propose a hard rock boring machine

Embodiment Construction
[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0016] refer to Figure 1-2 , a hard rock roadheader, comprising a roadheader main body 1, a shovel plate 2 is welded to the bottom of one side of the roadheader main body 1, a discharge chute 3 is opened on the side of the shovel plate 2 close to the roadheader main body 1, and the shovel plate 2 The interior is fixedly connected with the first drive motor 4 with the output shaft facing upwards, the end of the output shaft of the first drive motor 4 is welded with the installation box 5, and the inner wall of one side of the installation box 5 is fixedly connected with the second drive motor 6 arranged horizontally. The end of the output shaft of the second drive mo...

The invention discloses a hard rock heading machine which comprises a heading machine body. A shovel plate is welded to the bottom of one side of the heading machine body, and a discharging groove isformed in the side, close to the heading machine body, of the shovel plate. A first driving motor with an output shaft upward is fixedly connected into the shovel plate, and a mounting box is welded to the tail end of the output shaft of the first driving motor. A horizontally-arranged second driving motor is fixedly connected to the inner wall of one side of the mounting box, and a cam is fixedlyconnected to the tail end of an output shaft of the second driving motor in a sleeving mode. Symmetrically-arranged scraping plates are welded to the two sides of the mounting box, and mounting grooves are formed in the bottoms of the scraping plates in the length direction. A plurality of second springs are connected to the inner walls of the tops of the mounting grooves. The structure is simple, design is novel, broken rock cannot be clamped between the scraping plates and the shovel plate when the scraping plates rotate, thus rigid abrasion between the scraping plates and the shovel plateis avoided, and the service life of the hard rock heading machine is prolonged.
Description
technical field [0001] The invention relates to the technical field of tunnel excavation, in particular to a hard rock boring machine. Background technique [0002] There are many types of roadheaders, which can be divided into ordinary machine and tunnel boring machine according to the operation object, and divided into open type roadheader and shield type roadheader according to the operation mode. When mining, especially in the underground mining of minerals with a large hardness coefficient or rock, this type of boring machine will be used. [0003] When the traditional roadheader is digging, it will convey the broken rock out of the tunnel at the same time, and when conveying the gravel, it needs to sweep the gravel onto the conveying device. The existing roadheader uses a scraper to scrape the gravel. The distance between the scraper and the scraper is fixed, and when the scraper rotates, it is easy to cause gravel to be stuck between the scraper and the scraper, so t...
