[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] like Figure 1-Figure 5 As shown, an anti-sticking coal cake tamping hammer includes a hammer rod 1 and a hammer head 2 arranged at the lower end of the hammer rod 1, a limited seat 3 is provided on the outside of the hammer rod 1, and a fixing frame 4 is provided on the outer surface of the limited seat 3. A telescopic rod 5 is provided at the lower end of the fixing frame 4. The front surface of the lower end of the telescopic rod 5 is rotatably connected to a knocking rod 6, and the outer surface of the lower end of the knocking rod 6 is provided with a knocking head 7. The outer surface of the right side of the hammer rod 1 is provided with an axle seat 8, and the inner surface of the axle seat 8 is rotatably connected to a tooth block 9. The lower surface of the tooth block 9 is a vertical surface, and the upper surface is an inclined surface. The tooth block 9 can only rotate upward on the inner surface of the axle seat 8. Rotating downward will be restricted by the structure of the axle seat 8 itself and cannot be rotated downward. The surface is fixedly connected to a limiting block at the same time, which can prevent the tooth block 9 from being in a vertical state in the shaft seat 8, resulting in the failure of the knocking effect. A transmission mechanism 10 is provided on the surface of the knocking rod 6, and the transmission mechanism 10 includes a wheel 101 fixedly connected to the left outer surface of the knocking rod 6. The front surface and the right surface of the telescopic rod 5 are commonly fixedly connected to a fixed block 102, and the surface of the fixed block 102 is fixedly connected to a return spring 103, and the lower end of the return spring 103 is fixedly connected to the outer surface of the knocking rod 6. A protective sleeve 104 is provided on the outside of the return spring 103, and the protective sleeve 104 is fixedly connected to the fixed block 102 and the surface of the knocking rod 6, and the protective sleeve 104 can undergo elastic deformation.
[0025] By adopting the above technical solution, the hammer rod 1 and the hammer head 2 will move up and down with the external power device during operation to perform hammering. During the movement from bottom to top, the wheel 101 can contact the upper inclined surface of the tooth block 9. Under the limiting action of the tooth block 9, the knocking rod 6 rotates. Since the fixed block 102 at one end of the return spring 103 is fixed, the return spring 103 is stretched. When the wheel 101 is disengaged from the tooth block 9, since the lower surface of the tooth block 9 is a vertical surface, the return spring 103 instantly pulls the knocking rod 6 to knock on the hammer head 2, knocking off the coal stuck on the surface of the hammer head 2. The protective cover 104 can prevent debris from affecting the normal operation of the return spring 103. When the hammer rod 1 moves from top to bottom, the vertical surface of the tooth block 9 contacts the wheel 101, and the tooth block 9 will rotate upward in the shaft seat 8, and will not hinder the vertical passage of the wheel 101. This design can use the lifting and lowering of the hammer rod 1 itself to drive the knocking, effectively preventing the coal from sticking to the surface of the hammer head 2.
[0026] like Figure 1-Figure 7 As shown, the lower end surface of the fixing frame 4 extends to the interior and is provided with a slide groove 11, and the telescopic rod 5 is slidably connected to the interior of the slide groove 11. A plurality of card slots 12 are provided on the right outer surface of the telescopic rod 5. The right outer surface of the fixing frame 4 extends to the interior of the slide groove 11 and is threadedly connected to a locking screw 13, which can be snapped into the interior of the card slot 12.
[0027] Furthermore, a connecting plate 14 is fixedly connected to the upper surface of the hammer head 2 , and there are two connecting plates 14 .
[0028] Furthermore, a mounting hole 15 is formed through the lower end surface of the hammer rod 1, and a connecting plate 14 is mounted on the lower end of the hammer rod 1 through bolts and the mounting hole 15. The arrangement of the connecting plate 14 and the mounting hole 15 facilitates the disassembly of the hammer head 2.
[0029] Furthermore, a plurality of adjustment holes 16 are provided on the surface of the hammer rod 1 above the mounting hole 15 , an adjustment screw 17 is fixedly connected to the left outer surface of the shaft seat 8 , and the adjustment screw 17 is fixedly connected to the adjustment hole 16 of the hammer rod 1 through a nut.
[0030] Furthermore, a disassembly screw 18 is fixedly connected to the surface of the limiting seat 3 , and a corresponding hole is opened on the fixing plate of the fixing frame 4 .
[0031] Working principle: When using the anti-sticking coal cake tamping hammer, first, the hammer rod 1 and the hammer head 2 will move up and down with the external power device during the working process to perform hammering. During the movement from bottom to top, the wheel 101 can contact the upper inclined surface of the tooth block 9. Under the limiting action of the tooth block 9, the knocking rod 6 rotates. Since the fixed block 102 at one end of the return spring 103 is fixed, the return spring 103 is stretched. When the wheel 101 is disengaged from the tooth block 9, since the lower surface of the tooth block 9 is a vertical surface, the return spring 103 instantly pulls the knocking rod 6 to knock on the hammer head 2. Knock off the coal stuck on the surface of the hammer head 2. The protective cover 104 can prevent debris from affecting the normal operation of the reset spring 103. When the hammer rod 1 moves from top to bottom, the vertical surface of the tooth block 9 contacts the wheel 101. The tooth block 9 will rotate upward in the shaft seat 8 and will not hinder the vertical passage of the wheel 101. Loosen the locking screw 13 to slide and adjust the extension length of the telescopic rod 5. Install the adjusting screw 17 on the adjusting hole 16 at the appropriate position, and the knocking position of the knocking head 7 can be conveniently adjusted in accordance with the stroke of the hammer rod 1. This is the working principle of the anti-stick coal cake tamping hammer.
