[0019] The utility model is further described below in conjunction with specific drawings and embodiments.

[0020] like Figure 1-2 As shown: The utility model provides a wear-resistant hopper, which includes: a wear-resistant hopper body 1, a circular arc surface 11 is arranged on one side of the wear-resistant hopper body 1, and a slope 12 is arranged on the other side, and the thickness of the slope 12 decreases from the upper end to the lower end; an assembly hole 13 is arranged in the middle part of the circular arc surface 11.

[0021] The middle part of the arc surface 11 is concave inward, the curvature of the arc surface 11 is 38°~45°, and the inclination of the inclined surface 12 is 2°~3°; the bottom 14 of the wear-resistant hopper body 1 is arc-shaped, and the ends extend to the lower ends of both sides of the wear-resistant hopper body 1 respectively, and the curvature of the bottom 14 is 30°~40°. The upper ends of both sides of the wear-resistant hopper body 1 are not on the same horizontal plane, and the upper end of one side of the arc surface 11 is set higher than the upper end of the other side. The upper end connecting lines on both sides are set at an angle θ with the horizontal plane, wherein 25°<θ<50°; a bolt 2 is passed through the assembly hole 13, and the wear-resistant hopper is fixedly connected to the lifting crawler 4 by the bolt 2 and the nut 3, and the lifting crawler 4 is provided with a mounting hole for connecting the bolt 2; a plurality of wear-resistant hoppers are arranged at intervals on the lifting crawler 4.

[0022] The wear-resistant hopper is connected to the lifting crawler 4 by bolts 2 and nuts 3. The wear-resistant hopper is convenient and quick to assemble through structural improvement, and is not easy to loosen, and is convenient for daily replacement; the diameter of the installation hole of the lifting crawler is ∅11, and the hole spacing is 70mm. The number of wear-resistant hoppers to be installed is generally arranged according to the length of the lifting crawler of the shot blasting machine equipment originally configured. After the first drilling, only the wear-resistant hopper needs to be replaced in the future; the assembly hole 13 on the wear-resistant hopper has a size of ∅11 and has been cast, and no subsequent drilling is required, which reduces a lot of workload. The wear-resistant hopper has an arc surface, which makes the combination of the wear-resistant hopper and the lifting crawler more firm and not easy to loosen; the thickness of the inclined surface of the wear-resistant hopper decreases from the upper end to the lower end, which is more in line with the working conditions required for use; bolts and nuts are standard parts, which can be conveniently purchased on the market, saving the production cost of homemade products, and the lifting crawler 4 is a conventional general part of shot blasting equipment, which can be conveniently purchased on the market and can be cut according to the use length of the equipment.

[0023] Specific installation steps: first drill holes in the lifting track 4. The spacing between the wear-resistant hoppers is determined according to the equipment operating conditions and the actual number of requirements. After aligning the assembly hole 13 of the wear-resistant hopper with the position of the rubber track mounting hole, pass the bolt 2 through the mounting hole, and then tighten the bolt 2 with the nut 3. Because the hopper has a fastening concave surface, it is not easy to loosen after assembly. The number of wear-resistant hoppers required to be installed on the lifting track is generally arranged according to the length of the shot blasting machine equipment originally configured. As long as the first hole is drilled, only the wear-resistant hopper needs to be replaced in the future. It is convenient and quick to assemble, not easy to loosen, easy to replace daily, durable components, not easy to wear, and increased service life.

[0024] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
