Description

Bucket type grain elevator

Technical Field

The utility model belongs to the technical field of the technique of grain transportation storage and specifically relates to a bucket type grain lifting machine is related to.

Background

China is a large grain producing country, the amount of grains required to be stored every year is huge, steel plate grain storage bins are built in all over the country at present, the steel plate grain storage bins are generally high, and the process of transporting the grains into the steel plate grain storage bins is a key process of grain transportation and storage. The bucket elevator is a mechanical conveying equipment of a fixing device, is mainly suitable for continuously and vertically lifting powdery, granular and small materials, can be widely applied to lifting bulk materials of various scales of feed mills, flour mills, rice mills, oil mills, starch mills, grain depots, port docks and the like, and is equipment for conveying granular crops such as wheat, rice and the like from a low position to a high position. The basic working process is as follows: the hopper scoops up grain from the grain storage area of lifting machine bottom, and conveyer belt or chain rotate and promote the hopper to the top, walk around the top wheel back hopper upset downwards, and then rely on centrifugal force to pour the material into in the material outlet, by wide use in the grain storage transportation.

The current chinese utility model patent with publication number CN207671119U discloses a grain lifting machine, which includes: the device comprises a vertically arranged columnar shell, wherein a first driven wheel is arranged at the upper part of the shell, a second driven wheel is arranged at the lower part of the shell, the first driven wheel and the second driven wheel are connected through a first conveying belt, a discharge hole is formed at the upper part of the shell, a feed hole is formed at the lower part of the shell, hoppers are arranged on the first conveying belt at intervals, and a rotating shaft of the first driven wheel penetrates through the shell and is provided with a third driven wheel; the first driven wheel is connected with the third driven wheel through a transmission belt; and the driving motor is provided with a driving wheel, and the driving wheel is connected with the second gap bridge wheel through a transmission belt. This grain lifting machine adopts belt drive, can avoid the problem that the motor that chain drive trouble leads to burns out.

The above prior art solutions have the following drawbacks: when the hopper reaches the semicircular part at the top of the lifter along with the transmission belt, grain can be transferred from vertical motion to circular motion in a very short time along with the hopper, and at the moment, part of grain can be thrown away in a direction far away from the transmission belt due to sudden change of the motion direction; on the other hand, when the hopper reaches the position above the discharge port at the top of the elevator, the hopper throws out the grains in the hopper by virtue of centrifugal force, the grain elevator generally has higher running speed, the grains are thrown out generally more dispersedly, and the discharge port is away from the hopper by a certain distance, so that the grains are easily caused to fall into the bottom of the grain elevator directly from the inside of the elevator without being thrown out from the discharge port; in conclusion, the grain lifting machine is easy to cause the spilling and leaking phenomena, so that grain backflow is caused, the lifting machine works repeatedly, and the working efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a bucket type grain lifting machine, it has the effect that effectively reduces the grain backward flow at grain lifting process.

The above object of the present invention can be achieved by the following technical solutions:

the utility model provides a bucket-type grain lifting machine, is in including the cylindrical casing of erectting the setting first from driving wheel and the second of below of casing top are in from driving wheel, setting the discharge gate of casing top and the feed inlet and the setting of below are in the driving motor of casing top, driving motor with first from driving wheel between through retarder connection, first from driving wheel and second are connected through first conveyor belt from driving wheel between, the interval is provided with the hopper on the first conveyor belt, be equipped with 1/4 arc baffle between first conveyor belt top and the casing outer wall, arc baffle follows first conveyor belt straight flange begins rather than the turning point at semicircular top first conveyor belt semicircular top summit ends, arc baffle is laminated with the hopper surface towards the hopper one side.

Through adopting above-mentioned technical scheme, when the hopper was along with the vertical rebound of first conveyor belt to turn department, hopper direction of motion can change in the short time, trund into circular motion by vertical direction, because inertia, can lead to the grain in the hopper to have the trend of outside motion, the grain on hopper surface can outside unrestrained part, and the effectual grain that has blockked of convex baffle is outside unrestrained, when grain motion to the vertical top of belt, grain then is blockked by hopper self, and then effectively reduced the outside unrestrained of grain, the condition of grain backward flow has been alleviateed.
