The slipper back plate is used for forming a back bottom hook part of the guide slipper. The slipper main body is provided with a front side wear-resistant layer 111 and a rear top wear-resistant layer 113, the slipper bottom plate is provided with a front bottom wear-resistant layer 121, and the slipper rear plate is provided with a rear side wear-resistant layer 151 and a rear bottom wear-resistant layer 152. The front bottom wear-resistant layer 121 and the front side wear-resistant layer 111 are sequentially connected end to form an L-shaped groove with a notch facing to the rear upper side, and the rear top wear-resistant layer 113, the rear side wear-resistant layer 151 and the rear bottom wear-resistant layer 152 are sequentially connected end to form a double-side groove with a notch facing to the front. The track unit 2 comprises a front vertical plate 21, a rear vertical plate 22 and a plurality of track teeth 23 which are connected between the front vertical plate and the rear vertical plate and are distributed at left and right intervals. The bottom surface 211 and the front side surface 212 of the front vertical plate are both provided as hardened surfaces and are respectively in contact with and matched with the front bottom wear-resistant layer 121 and the front side wear-resistant layer 111 of the guide shoe. The upper part of the rear vertical plate is provided with a step protruding backwards, and the top surface 221 (including the top surface of the step), the rear side surface 222 of the step and the bottom surface 223 of the step of the rear vertical plate are all set as hardened surfaces and are respectively contacted and matched with the rear top wear-resistant layer 113, the rear side wear-resistant layer 151 and the rear bottom wear-resistant layer 152 of the guide shoe. The five hardened surfaces correspond to the five wear-resistant layers one by one, wherein the wear-resistant layers are thickened, and the hardened surfaces are matched to be beneficial to prolonging the wear life of the contact surfaces and improving the structural reliability of the walking meshing system.

And a material leakage guide surface which is inclined from low front to high back is arranged below the guide sliding shoe. The space between adjacent track teeth is the track tooth nest, and the track tooth nest and from the track tooth nest lower extreme along the space that the intermediate layer extends to the front below between piston shoe bottom plate and the guide face that leaks form first hourglass material passageway 81, and the teeth of a cogwheel tooth point top of walking wheel breaks the lump material that piles up in the track tooth nest to the mineral aggregate extrusion after will breaking gets into first hourglass material passageway. And a continuous downward second material leaking channel 82 is formed along the space extending from the lower part of the step to the front lower part along the interlayers among the parts of the sliding shoe rear plate, the rear vertical plate, the track teeth, the front vertical plate and the sliding shoe bottom plate and the material leaking guide surface. The first and second material leaking channels are arranged to ensure that the mineral aggregate (no matter the high-hardness mineral aggregate is in a soil shape or a block shape) around the track unit can be pushed out from the top of the track unit after being pushed by the guide sliding shoe and slides into the conveying groove from the tooth crest of the track unit, or is crushed and downwards enters the first material leaking channel, or the small mineral aggregate is directly extruded into the conveying groove through the second material leaking channel, or the mineral aggregate under the bottom surface 223 of the rear vertical plate step is extruded by the sliding shoe rear plate 15 and enters the second material leaking channel, so that the influence of mineral aggregate accumulation on the walking meshing system is avoided. The mineral aggregate flowing out of the first material leakage channel and the second material leakage channel finally enters the conveying groove 5. The lower bottom surface 234 of the rail tooth is a sloping surface with a lower front and a higher rear, which forms the top of the second leakage path with the bottom surface 224 of the rear vertical plate. As can be seen from a comparison of fig. 15 and 16, the mineral aggregate 91 such as lump material, which is pushed and discharged, can smoothly enter the conveying chute when the traveling engagement system of the present invention is used, while the mineral aggregate 92 accumulated at the track unit cannot be effectively discharged when the traveling engagement system of the conventional structure is used.
