Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given.

As shown in fig. 1-2, the wear-resistant hopper structure comprises a hopper body, wherein the hopper body comprises a receiving groove 1 and a guide groove 3, the guide groove 3 is obliquely distributed below the receiving groove 1, both the edges of a feed inlet of the receiving groove 1 and a discharge outlet of the guide groove 3 are provided with inward bent covered edges 4, and reinforcing ribs 41 are arranged outside the covered edges 4; the inner wall of the material receiving groove 1 is provided with a first wear-resistant plate 2, the bottom surface of the material guide groove 3 is provided with a second wear-resistant plate 31, the second wear-resistant plate 31 is provided with a plurality of salient points 32 and a blocking plate 33 inclining downwards, and the blocking plate 33 is provided with through holes 34.

The outside parcel of hopper body has sound-proof housing 42, is equipped with between sound-proof housing 42 and the hopper body and inhales sound cotton 43. The hopper body is subjected to noise reduction and silencing treatment by using the soundproof cover 42 and the sound absorbing cotton 43.

The first wear plate 2 and the second wear plate 31 are both connected with the hopper body through bolts. The disassembly is convenient.

The included angle between the plane of the top surface of the blocking plate 33 and the plane of the top surface of the second wear plate 31 is 120-150 °.

The corners of the blocking plate 33 are in a round corner structure. The sharp corners which are easy to be damaged are changed into round corners which are not easy to be damaged, and the damage condition of the blocking plate 33 is reduced.

The hopper is characterized in that a base 44 is arranged below the hopper body, a damping block 45, a supporting seat 46 and a damping spring 47 are sequentially connected between the base 44 and the hopper body from bottom to top, and the bottom of the supporting seat 46 is arranged inside the damping block 45. The height of the supporting seat 46 at the discharge opening of the material receiving groove 1 is lower than that of the supporting seat 46 at the feed opening of the material receiving groove 1. This design is guaranteed to connect the stable tilt state of silo 1, through snubber block 45 and damping spring 47's two-way shock attenuation, can better absorbing vibration, improves the shock attenuation effect.

The working principle is as follows: the arranged edge-covering 4 protects the fragile edges of the feed inlet and the discharge outlet of the hopper body, so that the edge strength is improved, and the strength of the edge-covering 4 is improved by using the reinforcing ribs 41; connect silo 1's inner wall to set up first antifriction plate 2, the bottom surface of baffle box 3 is equipped with second antifriction plate 31, all the other sides of baffle box 3 have also set up first antifriction plate 2, improve the wearability of hopper body through first antifriction plate 2 and second antifriction plate 31, wherein bump 32 and baffler 33 on the second antifriction plate 31 cooperate, make the crushed stone material reduce the area of contact with second antifriction plate 31 under bump 32 and baffler 33's separation effect, thereby reduce second antifriction plate 31 because of colliding with, the wearing and tearing that the striking led to the fact, the life of extension hopper, when first antifriction plate 2 or second antifriction plate 31 damage, can change, and need not maintain whole hopper, reduce maintenance duration and cost. Meanwhile, the blanking speed of the crushed stone can be reduced through the baffle plate 33, so that the crushed stone in the subsequent steps has sufficient time to be processed, and the subsequent processing effect is improved; the through holes 34 on the blocking plate 33 enable blocked fine stones to pass through, so that the fine stones are prevented from being accumulated on the blocking plate 33 to influence blanking, sharp corners which are easy to damage are changed into round corners which are not easy to damage, and the damage condition of the blocking plate 33 is reduced; in addition, the noise that produces when the hopper uses the unloading is inhaled sound cotton 43 and is absorbed, by the sound-proof housing 42 separation, and noise reduction effect is good, and the vibration that produces during the unloading is dual slowed down by snubber block 45 and damping spring 47, and shock attenuation effect is good.

The part of the utility model not detailed is prior art.
