Problems solved by technology

[0002] The punch frame of the reciprocating impact mining machine is set at the front of the reciprocating impact guide rod. Because the reciprocating impact excavator pushes the excavated material forward, the material washed down by the punch frame accumulates between the reciprocating impact guide rod and the punch frame and continues Increase the extrusion strength between the materials, causing the materials to easily enter the box seal between the reciprocating impact guide rod and the power box, resulting in damage to the box seal and oil leakage that cannot lubricate and cool the power system in the power box , the impact power system cannot work normally due to overheating and locking, causing the excavator to impact the material for several hours, and the box seal will be damaged. To replace the seal, the punch rack must be removed from the reciprocating impact guide rod, and then the seal It takes a long time to replace the parts and it is difficult to replace them. It is even more difficult to clean the remaining materials in the power box. It takes at least four hours to replace the box seals and it is extremely difficult to replace them at the mining site. In order to prevent the box seals from being damaged Damage should also be reduced by setting multiple seals on the reciprocating impact guide rod to increase the length of the reciprocating impact guide rod. In order to solve the above-mentioned problem that the box seal is easily damaged by direct contact with the material, in order to solve the problem that the seal sleeve and seal are difficult to disassemble and replace problem, the present invention proposes a mining machine rack wear-resistant seal sheath impact device

Embodiment 1

[0052] Such as figure 1 The impact device shown in the excavator gear frame wear-resistant sealing sheath 2 includes punching gear frame 1, box guard guide rod cover 3, gear frame wear-resistant sealing sheath 2, impact guide frame 5 and power box body 6, etc., and the impact guide The frame 5 is arranged in the power box body 6, and the box seal 7 etc. are arranged between the impact guide frame 5 and the power box body 6, and the box guard guide rod cover 3 is fixedly connected with the power box body 6, and the impact guide frame 5 includes The impact guide rod 4, etc., the end of the impact guide rod 4 is set at the box protection guide rod cover 3 outside the power box 6, the gear rack wear-resistant sealing sheath 2, etc. are arranged at the rear of the punch rack 1, and the punch rack 1. The rear part is connected with the impact guide rod 4. The wear-resistant sealing sheath 2 of the gear frame is arranged outside the cover 3 of the box body protection guide rod. The ...

Embodiment 2

[0060] Such as figure 2 , image 3 Shown is an impact device of a gear frame wear-resistant sealing sheath 2 for a mining machine. Gear frame sheath seals 9 are provided between the rod covers 3, and when the gear frame wear-resistant sealing sheath 2 is arranged inside the box guard guide rod cover 3, a gear frame wear-resistant sealing sheath 2 is provided outside The wear-resistant sealing surface 18 of the sleeve, and the wear-resistant sealing surface 18 of the sheath cooperates with the gear frame sheath seal 9 for sealing.

[0061] The gear rack sheath seal groove 21 can also be set on the gear rack wear-resistant sealing sheath 2, the gear rack sheath seal 9 is arranged on the gear rack sheath seal groove 21, and the gear rack sheath seal 9 is connected with the box body The inner cavity of the protective guide rod cover 3 is sealed, and the rack sheath seal 9 prevents material dust from entering the casing protective guide rod cover 3 and prevents the material from...

Embodiment 3

[0066] Such as Figure 4 , Figure 5 Shown is a mining machine tooth frame wear-resistant sealing sheath 2 impact device, the tooth frame sealing sleeve block 13 includes the fixed tooth frame sealing sleeve block inner circular surface 23, etc., and the impact guide rod 4 is provided with fixed teeth correspondingly. The outer circular surface 24 of the frame sealing sleeve stopper, the inner circular surface 23 of the fixed gear frame sealing sleeve stopper and the outer circular surface 24 of the fixed gear frame sealing sleeve stopper block cooperate to prevent the wear-resistant sealing sheath 2 of the gear frame from impacting the axial direction of the guide rod 4 Shake from side to side.

[0067] It is also possible to cooperate with the inner circular surface 23 of the fixed gear frame sealing sleeve block and the outer circular surface 24 of the fixed gear frame sealing sleeve block, and the sealing sleeve cooperates with the end face 16 of the gear frame and the en...

Abstract

The invention relates to the field of mining machines, in particular to an impact device for tooth frame abrasion resistance sealing protective sleeves of a mining machine. The tooth frame abrasion resistance sealing protective sleeves are arranged on the rear portion of a punching tooth frame and each comprise an overall tooth frame abrasion resistance sealing protective sleeve body or a split tooth frame abrasion resistance sealing protective sleeve body. Case body protecting guide rod covers are sleeved with the split tooth frame abrasion resistance sealing protective sleeve bodies. Tooth frame protective sleeve sealing pieces are arranged between the tooth frame abrasion resistance sealing protective sleeves and the case body protecting guide rod covers and comprise annular closed tooth frame protective sleeve sealing piece bodies and / or opening tooth frame protective sleeve sealing piece bodies. When the case body protecting guide rod covers are sleeved with the tooth frame abrasion resistance sealing protective sleeves, tooth frame sealing sleeve inner cavity abrasion resistance faces are sealed with the tooth frame protective sleeve sealing pieces in a matched mode. The distances between the front end faces of the case body protecting guide rod covers and the end faces, facing the case body protecting guide rod covers, of the tooth frame abrasion resistance sealing protective sleeves are larger than the reciprocating impact stroke. According to the impact device for the tooth frame abrasion resistance sealing protective sleeves of the mining machine, long-term cleaning of lubricating media in a power case body is guaranteed, and the service life of the reciprocating impact mining machine is prolonged by ten times.
