Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses a wear-resisting unloading pipe, including unloading pipe 1, unloading pipe 1 is for falling positive quadrangular frustum pyramid tubular structure. The four side walls in the blanking pipe 1 are respectively and detachably provided with a bottom plate 2. The bottom plates 2 are in a trapezoidal plate structure, and the inner walls of the blanking pipes 1 are covered inside by the four bottom plates 2 to form a passage for cement to pass through. One side of the bottom plate 2 departing from the blanking pipe 1 is fixed with a plurality of protection plates 3, and the surface of the protection plates 3 is vertical to the surface of the bottom plate 2. The protection plates 3 are evenly arranged on the bottom plate 2 from top to bottom in sequence, so that the intervals among the protection plates 3 are the same. A groove-shaped structure is formed between the adjacent protection plates 3, and cement can be remained between the adjacent protection plates 3 after the cement flows through the bottom plate 2, so that a cement protection layer is formed. The residual cement covers the upper surface of the protection plate 3, and when subsequent cement flows through the bottom plate 2, the subsequent cement firstly falls on the upper surface of the protection plate 3, and the subsequent cement cannot contact the surface of the protection plate 3 when falling on the protection plate 3 because the upper surface of the protection plate 3 is covered by the cement. Equivalently, the protection plate 3 is coated inside, so that the contact between cement and the protection plate 3 is reduced, and the abrasion of the cement to the protection plate 3 is reduced.

Referring to fig. 2 and 3, a plurality of reinforcing ribs 31 are fixed to the bottom surface of the shielding plate 3, and the reinforcing ribs 31 are uniformly arranged along the length direction of the shielding plate 3. The reinforcing ribs 31 are fixed on a common vertical plane of the protection plate 3 and the bottom plate 2 and are in a right-angled triangle structure. The reinforcing ribs 31 enhance the connection strength between the protection plate 3 and the base plate 2, and improve the structural stability of the protection plate 3. When cement falls on protection plate 3, can cause the impact to protection plate 3, and strengthening rib 31 can play the supporting role to protection plate 3, prevents that protection plate 3 from splitting under the impact of cement, has improved protection plate 3's life.

Referring to fig. 2 and 3, a wear-resistant rod 32 is fixed to one end of the shielding plate 3 away from the base plate 2 along the length direction. The cement can wash away from the one end of bottom plate 2 at protection plate 3 when falling from the top, and the cement that flows down from protection plate 3 also can produce the friction to the one end that protection plate 3 kept away from bottom plate 2. This results in the end of the apron 3 remote from the base plate 2 being a location where the whole apron 3 is worn more heavily. Wear-resisting pole 32 has improved the thickness that bottom plate 2 one end was kept away from to guard plate 3, and wear-resisting pole 32 surface is the arc, more is favorable to falling of cement. The wear rods 32 enhance the wear resistance and the service life of the apron 3. The cladding has wearing layer 33 on the guard plate 3, and wearing layer 33 has promoted the smoothness and the wearability of guard plate 3, and the resistance that receives when the cement flows through guard plate 3 is littleer, and the friction that produces between the guard plate 3 is littleer.

Referring to fig. 2 and 4, the bottom plate 2 is provided with a plurality of mounting holes 21. The mounting hole 21 is located below the shielding plate 3 and near the shielding plate 3. The mounting holes 21 are uniformly arranged along the length direction of the shielding plate 3. The mounting holes 21 are divided into three groups, and the three groups of mounting holes 21 are respectively positioned at the upper part, the middle part and the lower part of the bottom plate 2. The inner wall of the blanking pipe 2 is provided with a bolt hole matched with the mounting hole 21, and the bolt hole on the blanking pipe 2 is a blind hole. The mounting holes 21 on the bottom plate 2 are aligned with the bolt holes on the inner wall of the blanking pipe 2, and the bottom plate 2 can be fixed on the blanking pipe 1 by penetrating the mounting holes 21 with bolts. The inner wall of the blanking pipe 1 is fixed with a supporting block 4, and the supporting block 4 is positioned at the bottom end of the blanking pipe 1. The supporting shoe 4 supports the bottom at bottom plate 2, plays the supporting role to bottom plate 2, makes bottom plate 2 more firm on unloading pipe 1.

The implementation principle of the embodiment is as follows: a worker enters the blanking pipe 1 to tightly attach the bottom plate 2 to the inner wall of the blanking pipe 1, so that the mounting hole 21 in the bottom plate 2 is aligned with the bolt hole in the blanking pipe 1, and the bottom plate 2 is fixed on the blanking pipe 1 by penetrating the mounting hole 21 and the bolt hole in the bottom plate 2 through bolts.

The cement falls vertically from the flared end of the blanking tube 1, first onto the bottom plate 2. A groove capable of containing cement is formed between the upper surfaces of the base plate 2 and the protection plates 3, and cement can be remained between the upper surfaces of the base plate 2 and the protection plates 3 after flowing through the base plate 2. The residual cement covers the upper surface of the protection plate 3 of the bottom plate 2 to form a cement protection layer. As the cement continues to flow through the base plate 2 it will flow over the cement shield layer, thereby reducing wear on the base plate 2 and shield plate 3.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
