Feeding port for bulk machine

Abstract

The invention discloses a feeding port for a bulk machine. The feeding port comprises a feeding port wall, wherein a hopper is connected to the lower portion of the feeding port wall, a plurality of valve plates are arranged inside the feeding port, the centers of the two ends of each valve plate are connected with the feeding port wall through rotating shafts, and the valve plates are arranged in parallel; when each valve plate is in a horizontal state, the whole feeding hole is blocked; a swing rod is arranged outside the feeding port wall, a plurality of connecting pieces are hinged to the swing rod, and each connecting piece is fixedly connected with the rotating shaft on one side of the corresponding valve plate; and the swing rod is connected with a driving device, the driving device pushes and pulls the swing rod, and the swing rod drives the valve plates to rotate through the connecting pieces.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a material inlet of a bulk packing machine. Background technique [0002] Bulk loader is a kind of loading and unloading equipment mainly used for bulk powder materials, widely used in electric power, building materials, metallurgy, coal, grain and chemical industry and other fields. The bulk loader loads the materials from the material warehouse into trucks or ships. It can be interlocked with the feeding equipment under the material warehouse. When the tanker is full, it will automatically stop loading and realize the automation of the loading and unloading process. It has the characteristics of simple structure, reliable operation, high loading efficiency and relatively little dust pollution. It is an ideal equipment for loading bulk powder materials into trucks and ships. When people transport some dry powder and granular materials in bulk, they need to be loaded into vehicles. Most o...

Problems solved by technology

When people transport some dry powder and granular materials in bulk, they need to be loaded into vehicles. Most of the existing methods are to install feeding pipes, dust suction fans and material switch doors. The structure of such equipment is too simple. , when using it, it mainly relies on manual operation, the operation is complicated, and the feeding pipe is not closely matched with the loading port of the car. The material loading needs to be observed manually with the naked eye. If the control is not good, there may be too much material and the vehicle cannot be loaded. At the same time, it will also cause problems such as low vehicle loading efficiency and serious dust pollution.

[0003] Existing bulk machines, such as the invention patent: 20162005112X proposes a material bulk machine. This type of bulk machine can effectively improve the efficiency of bulk materials, and at the same time weigh each bulk material during the bulk process, and can reduce the dust generated during the bulk process. , but the feed port is too small, it is easy to cause the material to be stuck in the feed port. When the feed port needs to be closed in an emergency, the feed port cannot be closed in time, and the material keeps falling, which wastes the material

Invention patent: 2014105157023 proposes a feed inlet. The outer wall of the feed inlet is used to hold the material. When in use, the rotating handle is turned to drive the rotating body and the stirring device to rotate. Through the rotation of the stirring device, the material quickly enters the bulk machine. However, the feed port is often blocked due to too much material, resulting in unsmooth feed

Invention patent: 2018103484300 proposes a feed inlet structure on the rotary vibrating screen. The discharge outlet on the feed inlet and the fixed end of the soft connection are fixed by a throat hoop, and the fixed end of the soft connection is used to flang the inside of the feed inlet. The joint between the fixed end of the soft connection and the feeding port forms a smooth joint surface. There are no redundant burrs and shuttle angles, which overcomes the phenomenon of material accumulation at this joint. However, the joint between the soft joint and the throat hoop Easy to accumulate material, not easy to clean

But this feed port can't control the size of the falling material, and can't control the flow rate of the material
