Example two

In the practical use process, operators find that when tunneling a soft rock roadway through the device, the device cannot correspondingly adjust the rotating speed of the drill bit 4 according to the actual hardness degree of the rock stratum because the rock stratum is not regularly distributed, so that the drill bit 4 is excessively worn or broken in the use process, meanwhile, when the drill bit 4 is excavating the rock stratum, the integrity of the rock stratum can be broken, so that a large block of rock directly falls off, and because the collecting hopper 601 is provided with the rotary collecting plate 602, when the rotary collecting plate 602 contacts with the large block of rock, the rotary collecting plate 602 is limited to rotate, the rotary collecting plate 602 is damaged, and meanwhile, the rotary collecting plate 602 also can block the large block of rock from entering the conveying belt 603, so that the collecting treatment of the rock is not facilitated, and the device cannot correspondingly adjust the supporting force of the inserting plate 706 on the roadway according to the actual stress degree of the roadway, so that the device is improved according to the method described in the embodiment.

Firstly, when the device is used for tunneling a soft rock roadway, a first slider 514 on a rotary rod 513 is driven by a driving motor 512 to drive one end of a reciprocating rod 511 to reciprocate, so that a second slider 516 drives a swinging rod 518 to drive a rotary cylinder 519 to reciprocate, a movable cylinder 515 on a fixed block 521 is driven by the rotary cylinder 519 to rotate left and right, when the movable cylinder 515 rotates to be perpendicular to a support plate 520, the telescopic spring 504 is extruded, when the fixed block 521 drives the movable cylinder 515 to rotate to one side, the movable cylinder 515 is subjected to the elasticity of the telescopic spring 504, so that a movable striking rod 508 is driven to move on a sliding round rod 507, loose materials around the tunneling of a drill bit 4 are impacted reciprocally through a striking head 509, in the process, the displacement of the movable striking rod 508 is detected in real time by a displacement sensor arranged on the sliding round rod 507, because the rotation frequency and the rotation speed of the driving motor 512 are constant, the displacement of the movable striking rod 508 is also constant, if the displacement of the movable striking rod 508 is detected to be smaller than the preset range within a certain period of time, the rock stratum at the position is hard, the movable striking rod 508 cannot drive the striking head 509 to pierce the rock, so that the movable striking rod 508 cannot continue to move forwards, and similarly, if the displacement of the movable striking rod 508 is detected to be larger than the preset range within a certain period of time, the rock stratum at the position is softer, the movable striking rod 508 drives the striking head 509 to pierce the rock, so that the movement amount of the movable striking rod 508 is increased, at this time, the hardness degree of the rock stratum is detected by detecting the movement amount of the movable striking rod 508, and the rotation speed of the drill bit 4 is correspondingly regulated according to the rock stratum with different hardness degrees, the tunneling efficiency of the device is further improved, simultaneously, the problem that the device can not correspondingly adjust the rotating speed of the drill bit 4 according to the actual hardness degree of the rock stratum, so that the drill bit 4 is excessively worn or broken in the use process is effectively prevented.

Meanwhile, the degree of softness of the rock stratum is detected according to the displacement of the movable impact rod 508 detected by the displacement sensor, and the rotation rate of the rotary collecting plate 602 is adjusted in real time according to the degree of softness of the rock stratum, so that the problem that the rotary collecting plate 602 is damaged due to too high rotation speed when the rotary collecting plate 602 collects harder rock is prevented.

And through rotatory rubble cooperation accommodate motor 610 and the reciprocal rotation of rotating assembly that collect on the conveyer belt 603 of collecting the board 602 drive scraper blade 607 swing in the conveyer belt 603 top and carry out tiling with the rubble to will block up the rubble between rotatory collecting board 602 and conveyer belt 603, drive scraper blade 607 through rotating assembly and carry out the back-and-forth oscillation and carry out effectual breaking up to the rubble that blocks up in import department, prevent that the rubble from blockking up the unable problem of effectively collecting in import department.

Secondly, when the displacement of the movable impact rod 508 is detected through the displacement sensor, if the displacement of the movable impact rod 508 moving forward is detected to reach the maximum preset range, the rock in the area where the drill bit 4 is located is judged to fall off in advance in the tunneling process of the drill bit 4, in the process, the drill bit 4 is controlled to move up and down and left and right, the impact detection is carried out on the area through the movable impact rod 508, the size of the fallen rock is obtained, the electric push rod 9 is controlled to be in a freely telescopic state, in the state, when the rock moves to the collecting hopper 601, the rotary collecting plate 602 is pushed to move into the rotary groove 10, the elastic rods 11 arranged around the limiting disc 8 are extruded, so that the yielding of the fallen rock is realized, the problem that the fallen rock is effectively prevented from being overlarge in size, and the rotary collecting plate 602 is contacted with the rock and damaged is caused.
