Description

A dust keeper for concrete mixer promotes hopper

Technical Field

The utility model belongs to the technical field of concrete mixer hoisting device, especially, relate to a dust keeper that is used for concrete mixer to promote hopper.

Background

Before the bucket lifting type concrete mixer works, materials prepared in the batching plant need to be lifted into a mixing drum for mixing through a lifting hopper. In-process that the promotion begins to accomplish to unloading, mixer promotion hopper is uncovered state always, and concrete mixer's job site is mostly open-air or suburb, and wind is big and the weather is dry, has directly led to promoting a large amount of dusts in-process and has been raised by the wind, causes certain environmental pollution.

Disclosure of Invention

An object of the utility model is to improve the not enough of prior art and provide an adopt shield to seal the device that promotes the hopper, realize promoting the automatic opening and shutting of shield of hopper during operation to reduce the dust pollution of mixer promotion process.

The utility model aims at realizing like this, a dust keeper for concrete mixer promotes hopper, including promoting the hopper, promote the track, characterized by is equipped with the shield that covers the fill mouth at the fill mouth that promotes the hopper, the shield be close to promote the track side articulated with promoting the hopper, shield both sides middle part or front-mounted have the gyro wheel, it is equipped with rail brackets to promote track lower part both sides at concrete mixer, the gyro wheel can contact with rail brackets, rail brackets will be higher than the face of contact that promotes the hopper with the contact surface of gyro wheel and go up the plane, rail brackets's mounted position will satisfy the angle of opening of shield between 40 ~ 45.

Compared with the prior art, the utility model has the following characteristics of showing and positive effect: the utility model discloses an installation shield that can open and shut on promoting the hopper, two gyro wheels are installed to shield both sides face central point and put, promote the track both sides and are equipped with two rail brackets, promote the hopper and prolong when promoting the track and descend to rail bracket department, rail bracket holds up the shield through the gyro wheel, realizes that the shield opens, promotes the hopper and prolongs when promoting the track and rise to a take the altitude, and the shield drives the gyro wheel and breaks away from rail bracket, realizes that the shield is closed completely. The utility model discloses realize promoting the automatic dust cap that opens and shuts of hopper during operation to reduce the dust pollution of mixer promotion process.

Detailed Description

A dust-proof device for lifting hopper of concrete mixer, refer to fig. 1, fig. 2, there is a dust-proof cover 5 covering the mouth of the hopper at the mouth of the lifting hopper 6 of the conventional concrete mixer, the dust-proof cover 5 and lifting hopper 6 are near to the lifting track side and have connecting hinge seats, the hinge pin 3 connects the dust-proof cover 5 and lifting hopper 6 near to the track side through the hinge seat, the dust-proof cover 5 can rotate certain angle around the hinge pin 3, realize opening and closing, the middle part or front part of both sides of the dust-proof cover 5 installs the gyro wheel 4, this embodiment installs in the middle position, there are rail brackets 2 at both sides of the lower part of the lifting track 1 of the concrete mixer, the rail bracket 2 extends to the direction far from the lifting track 1, the extending length covers the complete movement track of the gyro wheel 4, the rail bracket 2 can contact with the gyro wheel 4, the contact surface of the rail bracket 2, and the installation position of the guide rail bracket 2 is required to meet the requirement that the opening angle between the dust cover 5 and the upper plane of the lifting hopper 6 is between 40 degrees and 45 degrees.

When the utility model works, as shown in fig. 3 and 4, when the lifting hopper 6 is lifted upwards along the lifting track 1 direction, the pin shaft 3 drives the hinge seat of the dust cover 5 to move upwards along the lifting track 1 direction, when the dust cover 5 reaches the horizontal state, the upper plane of the inner side of the dust cover 5 is completely contacted with the upper plane of the lifting hopper 6, and the roller 4 starts to be separated from the guide rail bracket 2, so as to realize closing; when the lifting hopper 6 descends to the guide rail bracket 2 from the top end of the lifting track 1, the guide rail bracket 2 supports the roller 4 and drives the dustproof cover 5, at the moment, the lifting hopper 6 continues to move downwards along the direction of the lifting track 1, and the dustproof cover 5 rotates around the pin shaft 3 and is gradually opened; when the lifting hopper 6 descends to the bottommost end of the lifting track 1, the lifting hopper stops after being touched to limit, and the dust cover 5 finishes the uncovering action.

The utility model discloses need not to increase any power, effectively reduced the bucket and carried the dust pollution problem of formula concrete mixer promotion hopper when promoting, it is effectual to seal.

Claims

1. The utility model provides a dust keeper for concrete mixer promotes hopper, including promoting the hopper, promote the track, characterized by is equipped with the shield that covers the fill mouth at the fill mouth that promotes the hopper, the shield be close to promote the track side articulated with promoting the hopper, shield both sides middle part or front-mounted have the gyro wheel, promote track lower part both sides at concrete mixer and be equipped with rail brackets, the gyro wheel can contact with rail brackets, rail brackets will be higher than promoting the hopper upper plane with the contact surface of gyro wheel, rail brackets's mounted position will satisfy the angle of opening of shield and between 40 ~ 45.
