in an alternative embodiment, the right end face of the fixing rod 12 and the left end face of the screw rod 13 are fixedly connected by a bolt.

In this embodiment: the fixing rod 12 and the screw rod 13 are fixed through bolts, so that the screw rod 13 is convenient to install or replace, a new screw rod 13 is convenient to replace, and the coal mining efficiency in the later period is improved.

The working principle and the using process of the invention are as follows: the user can hold the push rod 3 by hand under the cooperation of the walking wheels 5, the use place of the device when the device is moved can be controlled or fixed on a driving vehicle by the hand by the push rod 3, when the spiral rod 13 is driven by the motor 11 in the fixed groove 15 of the fixed frame 10 to rotate to mine coal, the coal seam is convenient to insert because the drill bit 14 is in a taper shape, under the cooperation of the second spring 24, the drill bit 14 is buffered, the excavation force of the drill bit 14 is enhanced while the drill bit 14 is protected, the mining progress is facilitated to be accelerated, the coal seam is tunneled into small blocks by the drill bit 14 and the spiral rod 13, the elastic effects of the third spring 26 and the backing plate 27 are realized, the fixed rod 12 can slide in the through groove 25, the fixed rod 12 and the spiral rod 13 have the buffering effect, the direct impact on the spiral rod 13 is avoided, the rod 13 is facilitated to be protected, and the slide rod 29 slides in the through groove 28 and the connecting, under the control of the two fourth springs 30, the elastic effect of the screw rod 13 is enhanced again, the buffering performance is enhanced, the fixing rod 12 is fixedly connected with the screw rod 13 through a bolt, the screw rod 13 is convenient to detach and replace, the conveying frame 7 is fixed to the upper surface of the bottom plate 6 under the matching of the bottom plate 6, the right end of the conveying frame 7 is rotatably connected with the bottom plate 6 through a rotating shaft, the telescopic shafts of the two telescopic mechanisms 8 stretch to drive the left end of the conveying frame 7 to move up and down, the conveying height of the conveying frame 7 is adjustable, the conveying frame is convenient to adjust according to the height of a bearing point of coal, the sliding plate 18 slides out of the inner part of the baffle plate 9, when the sliding plate 18 slides out of the inner part of the baffle plate 9, the plurality of convex blocks 20 are extruded into the inner part of the groove 21 under the elasticity of the first spring 22, and after the sliding plate slides to the required height, the first spring 22 drives the, the fixing of the sliding plate 18 can be completed, the baffle plate 9 and the sliding plate 18 play a role of enclosing and blocking two ends of the conveying frame 7, the probability of coal falling is reduced, the small coal blocks fall to the upper surface of the conveying frame 7 to complete conveying, the friction force between the coal blocks and the conveying belt of the conveying frame 7 is enhanced because the connecting belt 19 is made of silica gel, the small coal blocks are not easy to fall, the width of the shielding cloth 2 is larger than the length from the bottom surface of the fixing plate 1 to the bottom surface of the hydraulic rod 4, the two shielding cloths 2 form a semi-surrounding shape between the bottom surface of the fixed plate 1 and the four hydraulic rods 4, inhibit the raising of partial dust, are beneficial to building a good working environment, meanwhile, because the transparent plate 16 is made of transparent material, the user can look down the conveying condition of the coal directly from the fixed plate 1, and then, the transparent plate 16 is cleaned by moving the scraper 17 back and forth, which is beneficial to the optimization of the environment.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
