Two-way reclaiming hopper of bucket wheel mixing reclaimer

Abstract

The invention relates to a two-way material taking hopper of a uniform mixing and material taking machine. The two-way material taking hopper comprises a bucket body, a supporting seat, a pin shaft and a pressure plate. The bucket body is formed by welding two side plates and two top plates, a symmetrical two-way opening form is formed, wherein the length of the two top plates is slightly smallerthan the length of the contact part between the bucket body and the supporting plate, the 2 / 3 area parts, near the supporting seat, of the side plates are in an arc shape, and the 1 / 3 area parts, nearthe top plates, of the side plates are in an obtuse angle opening shape. The two-way material taking hopper does not need to perform manual bucket changing work when materials are taking in a reversing mode, the structure has good stress condition, the work efficiency is high, the materials are saved, welding and machining quantity is reduced, the detecting costs of the materials, welding and weld quality are saved, and manpower, material resources and time costs when buckets are changed are further saved.

Description

technical field [0001] The invention belongs to the technical field of material transportation, and in particular relates to a two-way reclaimer of a bucket-wheel mixing reclaimer. Background technique [0002] The bucket wheel mixer reclaimer is a large-scale bulk material continuous conveying machine widely used in steel mills, aluminum plants, mines, etc. . The bucket wheel mixing and reclaiming machine is composed of bucket wheel mechanism, trolley mechanism, bridge frame, bridge belt conveyor, rake frame mechanism, walking mechanism, electrical system and many other components. The reclaiming range of the bucket wheel mixing reclaimer ranges from 100T / H to 3500T / H, and is customized according to the needs of each production enterprise. The reclaimer adopts a heavy-duty working system, and the annual working time is more than 330 days. Every time after taking out a material from the stockyard, it is necessary to manually change the direction of the hopper before retrie...

AI Technical Summary

Problems solved by technology

The pin shaft form is cumbersome to manufacture. It is necessary to match the fixed lug plate of the hopper with the main body of the wheel body, and then assemble and weld, which is time-consuming and costly; the structure of the press plate is simple and can be adjusted by the waist hole of the press plate , easy to install and make, but the use effect is not ideal, the pressure plate is easy to damage, and the pressure plate cannot be pressed tightly after the bucket is worn, which affects the normal operation of the reclaimer; the structure of the tie rod is simple and easy to install and make, but the tie rod is easily deformed during use. The gap between the backward bucket and the wheel body is too large, and the use effect is not ideal

The above three structural forms all require manual reversing when the reclaimer performs reversing operations, and it requires the cooperation of multiple people, and even under harsh conditions, it is necessary to use auxiliary machinery and equipment, which is time-consuming, laborious and costly.

[0004] Chinese patent (CN201620346065.6) provides a mixing reclaimer bucket wheel that changes the opening direction of the hopper through a driving device. At the same time, the fixation is insufficient, and it is easy to deviate from the direction of feeding, and even the feeding directions and angles of different hoppers are inconsistent, resulting in jamming during the feeding process and uncoordinated mutual forces.

[0005] As mentioned above, although there are many structural forms of the retrieving hopper, the existing technology has various deficiencies in production and use, and the performance of the machine is unstable during the use of the machine, which cannot meet the heavy-duty production needs.
