Description

Anti-abrasion chute

Technical Field

The utility model relates to a elephant trunk is used in grain transport.

Background

In grain conveying, the grain conveying is generally carried out through a chute, so that grains flow in the chute, and the grain transfer is realized in sequence.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem who solves: the existing chute is a rectangular pipeline formed by welding four plates, and in the process of grain flowing, the grain and the bottom plate of the chute have large friction force, so that the bottom plate has serious friction, and the service life of the chute is shortened.

The technical scheme of the utility model specifically does:

the utility model provides an abrasionproof decreases elephant trunk, its whole hollow column pipeline that is including fixed roof, a bottom plate, two curb plates together, the fixed antifriction subassembly of upper surface of bottom plate, antifriction subassembly is cut apart into a plurality of grain buffer unit with the bottom plate.

The anti-friction component is of a grid type and comprises a plurality of flat steels which are vertical to each other, the flat steels are welded on the upper surface of the bottom plate, and the space enclosed by the flat steels is the grain cache unit.

The antifriction subassembly includes many parallel big-end-up's T shaped steel down, and the lower surface of two curb plates is equipped with the T-slot, and the T-slot is similar with the cross sectional shape of T shaped steel, and the both ends of T shaped steel all stretch into the T-slot, and the space between two adjacent T shaped steel is exactly grain buffer memory unit.

The T-shaped steel is in interference fit with the T-shaped groove.

Compared with the prior art, the technical effect of the utility model is that, the utility model discloses be equipped with antifriction subassembly, avoided grain direct friction bottom plate, reduced the loss of bottom plate, can prolong the life of elephant trunk.

Detailed Description

Referring to fig. 1-5, an anti-wear chute is a hollow cylindrical pipeline, and comprises a top plate 10, a bottom plate 11 and two side plates 12 fixed together, wherein an anti-friction component 20 is fixed on the upper surface of the bottom plate 11, and the bottom plate 11 is divided into a plurality of grain buffer units 29 by the anti-friction component 20.

The anti-friction assembly 20 has the following two options:

A. referring to fig. 1-3, the anti-friction assembly 20 is of a grid type and includes a plurality of flat bars 22 perpendicular to each other, the flat bars 22 are welded on the upper surface of the bottom plate 11, and a space enclosed by the flat bars 22 is a grain buffer unit 29.

In this way, the anti-friction component is welded with the bottom plate and is firmer. But also has a disadvantage: if the flat steel 22 is worn to the extent that it needs to be replaced, the replacement is troublesome.

B. Referring to fig. 4 to 5, the anti-friction assembly 20 includes a plurality of parallel T-shaped bars 25 having a large lower portion and a small upper portion, the lower surfaces of the two side plates 12 are provided with T-shaped grooves 30, the cross-sectional shapes of the T-shaped bars 30 are similar to those of the T-shaped bars 25, and both ends of the T-shaped bars 25 are inserted into the T-shaped grooves 30, so that the space between two adjacent T-shaped bars 25 is the grain buffer unit 29.

In this way, the T-section steel 25 is also fixed to the bottom plate 11, and the advantages are: if the T-section steel 25 is worn seriously, it can be replaced.

When replacing, one end of the T-section steel 25 is struck with a punch to cause the T-section steel 25 to exit from the other end. Then, one end of the new T-section 25 is placed in the T-shaped groove 30, and the T-section 25 is hammered in until it extends into the T-shaped groove 30 at the other end.

For rigidity, the T-bar 25 is interference fit with the T-shaped channel 30.

The working principle is as follows:

when the grains flow in the chute, part of the grains can be temporarily stored in the grain buffer unit 29, the part of the grains can rub against the flowing grains, and the part of the grains basically do not rub against the bottom plate 11, so that the bottom plate is protected, and the service life of the bottom plate is prolonged.

See the prior art for additional details.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
