Sealing device for material bucket capable of stirring concrete

Abstract

The invention relates to a sealing device for a material bucket capable of stirring concrete. The sealing device comprises a bucket body, wherein a stirring shaft driven by a hydraulic motor is rotatably mounted in the bucket body, an intermediate impeller is fixedly installed in the middle of the stirring shaft, a left spiral blade and a right spiral blade which are opposite to each other in rotation direction are arranged on the two sides of the intermediate impeller correspondingly, bearing boxes are mounted on the two side walls of the bucket body correspondingly, bearing chambers are arranged in the bearing boxes correspondingly, bearings are installed in the bearing chambers, the stirring shaft is mounted on the bearings, and the hydraulic motor is located on the outer side of the bucket body and is mounted on the bearing boxes. The device has the following effects that 1), a double oil seal structure of a framework oil seal and a mechanical seal assembly is adopted, the sealingcapability of the product in a harsh environment is improved, and the service life of the product is prolonged; 3), an impeller cover is in a frustum shape, materials can be prevented from being bonded to a mechanical seal box, cleaning is convenient, secondary sealing can be carried out on the mechanical seal box, and the sealing effect is improved.

Description

technical field [0001] The invention relates to a sealing device for a hopper capable of stirring concrete. Background technique [0002] Materials need to be mixed in housing construction, road construction sites, fertilizer, feed, brewing and other industries. At present, the commonly used mixing methods are: 1. Manual mixing: but this method has many defects such as high labor intensity, low efficiency, and uneven mixing. 2. Manual feeding and mixer mixing: This method is manually or manually assisted feeding, and the labor intensity is also very high, and the fixing of the mixer and the inconvenience of transition, these defects greatly limit its application. 3 Mixing with a special fixed mixer: this method can only be used for special purposes, and cannot be widely used. 4. Mixing station and mixer truck: This method requires a dedicated site. [0003] In order to overcome these defects, a faster loader is usually used for concrete shipment. However, the traditional ...

AI Technical Summary

Problems solved by technology

At present, the commonly used mixing methods are: 1. Manual mixing: However, this method has many defects such as high labor intensity, low efficiency, and uneven mixing.

2. Manual feeding and mixer mixing: this method is manually or manually assisted feeding, and the labor intensity is also very high, and the fixing of the mixer and the inconvenience of transition, these defects greatly limit its application

3 Mixing with a special fixed mixer: this method can only be used for special purposes, and cannot be used on a large scale

4. Mixing station and mixer truck: this method requires a dedicated site

[0003] In order to overcome these defects, faster loaders are usually used when concrete is shipped. However, traditional loaders can only perform simple shoveling and transportation, and have no mixing function, and the function is relatively single
