Description
Technical Field
The utility model relates to a material feed bin technical field, in particular to stifled device is prevented to feed bin discharge gate.
Background
The material bin is one of the common equipment in modern industrial production, can hold raw materials, finished product or semi-manufactured goods in the production process, wherein, the feed bin for holding raw materials such as raw coal, grain, mineral aggregate because do not need accurate ejection of compact control, only set up a simple discharge gate in the bottom of feed bin usually, open the discharge gate when needing the blowing can, its manufacturing and maintenance cost are lower, are applicable to the rough machining or the scene of preprocessing of material. In actual production processes, such silos are often used in conjunction with belt conveyors in order to transport material discharged from the silo in time to be processed elsewhere. In order to reduce the waste caused by impact on the belt conveyor and the jet of the materials per se when the materials fall from a high position, the material receiving end of the general belt conveyor can be close to the discharge hole of the storage bin as much as possible, but if the discharge speed of the storage bin is too fast, the arrangement can lead to the accumulation of the materials on the material receiving end of the belt conveyor to overflow, even block the discharge hole of the storage bin in serious conditions, and the production efficiency is reduced. In order to avoid this, a specially-assigned guard is generally required, which increases the labor cost required for production.
SUMMERY OF THE UTILITY MODEL
In view of the above situation, the utility model aims at providing a stifled device is prevented to feed bin discharge gate, the device simple structure can prevent that the discharge gate from blockking up according to the distance of the big or small adjustment the device of feed bin ejection of compact speed and discharge gate.
In order to achieve the above object, the present invention is realized by the following technical solutions:
an anti-blocking device for a discharge port of a material bin comprises a rack and a belt type conveying mechanism arranged on the rack, wherein a transverse supporting shaft is arranged at the lower part of the discharge end of the belt type conveying mechanism, and two ends of the transverse supporting shaft are respectively and rotatably connected to the rack; belt conveyor's material end that connects sets up in feed bin discharge gate below through the elastic response subassembly, the elastic response subassembly includes horizontal layer board, spacing post and elastic support piece, the length of horizontal layer board is greater than belt conveyor's width, and horizontal layer board setting is in the lower part of belt conveyor material end, and the both ends of horizontal layer board are equipped with the spacing hole of bar respectively, and the vertical spacing post of wearing to be equipped with respectively in every spacing hole of bar, the bottom fixed connection of spacing post is in the frame, the top is equipped with the locating part, and the below of horizontal layer board is still vertical to be provided with a plurality of elastic support piece, elastic support piece's top links to each other with horizontal layer board, and the bottom links to each other with the frame.
It should be noted that the belt conveying mechanism is configured conventionally in the art, and includes, for example, a frame body, rotating rollers disposed at two ends of the frame body, a conveying belt wound around the rotating rollers, a plurality of carrier rollers disposed in parallel between the rotating rollers, and a power assembly and an associated transmission assembly for providing power for rotation of the rotating rollers.
In the utility model, the transverse supporting shaft at the discharging end of the belt type conveying mechanism is rotationally arranged on the frame, so that the belt type conveying mechanism can rotate around the axis of the transverse supporting shaft, and the elastic return component arranged below the receiving end of the belt type conveying mechanism can adjust the distance between the belt type conveying mechanism and the discharging port of the storage bin according to the blanking speed of the storage bin; namely, when the feeding speed is too high, the accumulation amount of the materials at the material receiving end of the belt type conveying mechanism is increased, the pressure of the belt type conveying mechanism on the elastic return assembly is increased, the elastic supporting piece is stressed and compressed and stores energy, so that the material receiving end of the belt type conveying mechanism is far away from the material outlet of the storage bin, and the blockage of the materials is prevented; on the contrary, when the blanking speed is slowed down, the accumulation amount of the material at the material receiving end of the belt type conveying mechanism is reduced, the pressure of the belt type conveying mechanism on the elastic return assembly is reduced, the elastic potential energy stored before is released by the elastic supporting piece and extends, the material receiving end of the belt type conveying mechanism is pushed to be close to the material outlet of the material bin, and the impact of the material on the belt type conveying mechanism and the jet of the material per se are reduced. When the material receiving end of the belt conveying mechanism rotates up and down, the limiting column is matched with the strip-shaped limiting hole, so that the belt conveying mechanism can be prevented from deviating from a discharge port of a storage bin in an auxiliary manner.
Furthermore, the limiting part is a limiting nut, and the limiting nut is in threaded connection with the limiting column. The limiting nut in threaded connection can prevent the transverse supporting plate from separating from the limiting column due to overlarge upward rotation amplitude, and the assembly of the elastic return assembly is facilitated; in addition, the height of the limiting nut is adjusted, so that the nearest distance between the belt type conveying mechanism and the bin discharge port can be limited, and the belt type conveying mechanism is prevented from being directly attached to the bin discharge port when no load exists.
Further, the elastic supporting piece is a spring.
Furthermore, the number of the springs is three, and the springs are uniformly distributed along the length direction of the transverse supporting plate so as to uniformly distribute the stressed pressure.
The utility model discloses in still including making this feed bin discharge gate prevent other subassemblies of stifled device normal use, all belong to the conventional selection in this field. Additionally, the utility model discloses in not all adopt the conventional means in this field with limited device or subassembly, for example, frame, horizontal die-pin, feed bin, spacing post, the spacing hole of bar, stop nut, spring etc. all adopt conventional setting.
Compared with the prior art, the beneficial effects of the utility model are that:
the device can automatically adjust the distance between the receiving end and the discharge port of the storage bin by arranging the elastic return assembly according to the blanking speed of the storage bin, so that materials are prevented from being accumulated and blocked at the discharge port, and the labor cost is saved; in addition, the device has simple structure, convenient maintenance and good practicability.
