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 hopper under trucd mixer installs and assists the ejection of compact in the below of going out feed bin 1, hopper 2 including the slope setting. The discharging hopper 2 is fixedly arranged on the mixer truck and is positioned below the discharging bin 1. The lower hopper 2 is of an arch structure, and mounting blocks 21 are respectively fixed on two sides of the lower hopper 2 along the length direction. The lower hopper 2 is internally detachably connected with a friction plate 3 with an arch structure, and the friction plate 3 covers the inner wall of the lower hopper 2. Referring to fig. 3, the length of the friction plate 3 is greater than the length of the lower hopper 2 such that the friction plate 3 protrudes outward from the bottom end of the lower hopper 2 when the friction plate 3 is mounted on the lower hopper 2. The friction plate 3 has stopper blocks 31 fixed to both sides thereof in the longitudinal direction.

Referring to fig. 4 and 5, the surfaces of the two mounting blocks 21 adjacent to each other are provided with a slot 22 along the length direction, and the slot 22 is a T-shaped slot. The limiting block 31 is a T-shaped block which can be inserted into the slot 22 in a matching manner, so that the limiting block 31 is not easy to fall off from the slot 22 after being inserted into the slot 22.

Referring to fig. 4 and 6, the bottom end of the mounting block 21 is fixed with a blocking block 23, and the blocking block 23 seals one end of the slot 22, so that the limiting block 31 is inserted into the slot 22 from one end of the slot 22 along the slot length direction and then abuts against the blocking block 23, and the limiting block 31 is prevented from falling off from the slot 22.

Referring to fig. 2 and 4, a through hole is formed at one end of the mounting block 21 away from the blocking block 23, and the through hole penetrates through the mounting block 21. A limiting column 24 penetrates through the through hole, and the axial direction of the limiting column 24 is vertical to the length direction of the mounting block 21. One end of the limiting column 24 is fixed with a baffle 25, and the other end of the limiting column penetrates through the through hole and extends outwards. When the limiting column 24 is arranged on the through hole in a penetrating mode, one end, away from the blocking block 23, of the clamping groove 22 can be sealed. The limiting column 24 is sleeved with a spring 26, one end of the spring 26 is fixed on one side of the baffle 25 close to the mounting block 21, and the other end of the spring 26 is fixed on one side of the mounting block 21 close to the baffle 25. When the spring 26 is in a natural state, the limiting column 24 penetrates through the mounting block 21 and seals the clamping groove 22. When the stopper post 24 is withdrawn from the through hole, the spring 26 is in a stretched state.

Referring to fig. 1 and 6, the bottom end of the discharging hopper 2 is rotatably provided with an extension hopper 4, and the extension hopper 4 and the discharging hopper 2 have the same structure and are both of an arch structure. The extension hopper 4 is rotatably connected to the semicircular end face of the blanking hopper 2, and the length of the extension hopper 4 is smaller than that of the blanking hopper 2. The extension hopper 4 can be turned downwards and abutted against the lower hopper 2 to form a passage for concrete to pass through together with the lower hopper 2. The friction plate 3 covers the upper part of the joint of the extension hopper 4 and the lower hopper 2, and concrete is prevented from leaking from the joint. Extension fill 4 can upwards overturn the lock in hopper 2's top down, and it is cylindric to enclose with hopper 2 down, has realized the swift of extension fill 4 and has accomodate.

The implementation principle of the embodiment is as follows: the concrete tank truck has large transportation volume and long time for blanking, and can generate large abrasion to the friction plate 3 due to the characteristics of concrete. Because the friction plate 3 covers the upper part of the blanking hopper 2, the abrasion of the blanking hopper 2 caused by concrete is avoided. When the friction plate 3 is seriously abraded, the friction plate can be conveniently replaced. Referring to fig. 4, during replacement, the worker pulls out the stopper post 24 from the through hole, so that the stopper 31 can be pulled out upward from the notch 22 along the length of the notch. After the worn friction plate 3 is pulled out, a new friction plate 3 is taken out and replaced. The stopper posts 24 are pulled out from the through holes, so that the stoppers 31 of the friction plate 3 can be inserted into the notches 22 along the length direction of the notches 22. Because the draw-in groove 22 is T type groove, stopper 31 is T type piece, and stopper 31 pegs graft in draw-in groove 22 back more stable, can not produce in draw-in groove 22 and rock. Referring to fig. 2, when the stopper 31 abuts against the block piece 23, the stopper post 24 is released, and the stopper post 24 is inserted into the through hole by the spring 26. The stopper 31 is surrounded by the locking groove 22, the blocking piece 23 and the stopper post 24, so that the friction plate 3 is fixed on the lower hopper 2.

Referring to fig. 1, when the feeding distance is not enough, the extension hopper 4 is turned downwards, so that the extension hopper 4 and the feeding hopper 2 form a passage for concrete to pass through. Referring to fig. 6, after the extension hopper 4 is used, the extension hopper 4 is turned upwards and is buckled on the lower hopper 2, so that the extension hopper is convenient for workers to rapidly store.

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.
