Description

Technical Field

[0001] The utility model relates to a hopper, in particular to a dust suppression hopper for unloading grain from a grain silo. Background Art

[0002] Grain unloading refers to the process of taking grain out of the granary. The main ways of unloading bulk grain include loading in a loading shed, gravity flow in a silo, and directly from a ship to a truck. Bulk grain falls quickly from a ship or warehouse to a transport vehicle. During this process, dust and light impurities in the grain material will float into the air. In addition, the grain material will shear against the air during its falling process. The high-speed airflow squeezed out by the grain material will carry dust and light impurities around, and a large amount of dust will spread into the surrounding environment. Due to the small size, light weight and slow settling speed of dust particles, the grain loading and transshipment site will remain dusty for a long time, which will harm the health of the loading workers and pollute the atmospheric environment.

[0003] An electrically controlled dust suppression and dispensing hopper for discharging materials from a grain silo with publication number CN216511666U comprises an outer cylinder and an inner cone, a funnel-shaped discharging cone is arranged at the lower end of the outer cylinder, a dust cover is arranged at the upper end of the outer cylinder, a feed pipe connected to the inner cavity of the outer cylinder is arranged laterally of the outer cylinder, the feed pipe is arranged obliquely downward, the discharging cone is detachably connected to the lower end of the outer cylinder, an inner cone is arranged in the outer cylinder, the inner cone is coaxially arranged with the outer cylinder, an electric actuator which can be remotely controlled is arranged above the dust cover, the output shaft of the electric actuator is connected to the adjusting screw, the adjusting screw is threadedly connected to the upper end of the inner cone, the electric actuator drives the rotation of the adjusting screw, and drives the inner cone to move up and down, thereby realizing the adjustment of the gap size between the inner cone and the outer cylinder.

[0004] The above device can effectively prevent the dust and light impurities in bulk grain materials from spreading due to high-speed flow, and can play a good dust suppression effect. However, the feed pipe in the above device is arranged on the side, so that the grain cannot enter and fall to the middle position of the cylinder, which will lead to the grain circulation being not smooth enough. In addition, in order to achieve a good dust suppression effect, the above device uses more parts, which will greatly increase the production cost. Utility Model Content

[0005] The utility model aims to solve the problems of the prior art that grain circulation is not smooth enough and that many parts are used, and proposes a dust suppression hopper for grain storage out of the warehouse.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A dust suppression hopper for grain silo discharge, comprising a cylindrical barrel, a conical barrel and a grain guide assembly, wherein the bottom of the cylindrical barrel abuts against the top of the conical barrel, the outer surface of the bottom of the cylindrical barrel and the outer circumference of the top of the conical barrel are both provided with flanges, and the two flanges are fixed by screws, a feed pipe is provided in the middle of the top surface of the cylindrical barrel, and a discharge pipe is provided at the bottom of the conical barrel, and the discharge pipe is arranged concentrically with the feed pipe;

[0008] The grain guiding assembly includes an upper hollow cone located in the cylindrical cylinder and a lower hollow cone located in the conical cylinder, thereby forming a channel for grain to pass between the cylindrical cylinder and the upper hollow cone, and between the conical cylinder and the lower hollow cone. The bottom of the upper hollow cone is fixedly connected to the top of the lower hollow cone, and the connection between the upper hollow cone and the lower hollow cone is fixed to the inner wall of the conical cylinder by three to four supporting columns. There is a certain distance between the lower hollow cone and the discharge pipe, and the bottom of the lower hollow cone is open.

[0009] Preferably, the taper of the lower hollow frustum is consistent with the taper of the conical cylinder.

[0010] Preferably, a flange is provided on the outer circumference of the top of the feed pipe.

[0011] Compared with the prior art, the utility model provides a dust suppression hopper for grain storage, which has the following beneficial effects:

[0012] When the present application is used to assist grain in unloading, air can flow upward along the lower hollow cone with an open bottom, and dust can sink downward, thereby effectively preventing dust from spreading in the grain and achieving a good dust suppression effect. In addition, a hollow grain column is formed in the middle during the falling process of the grain, thereby improving the smoothness of grain circulation. The entire device uses fewer parts and is more convenient to assemble, thereby effectively reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The grain guide assembly includes an upper hollow cone 7 located in the cylindrical barrel 1 and a lower hollow cone 8 located in the conical barrel 2, so as to form a passage for grain to pass between the cylindrical barrel 1 and the upper hollow cone 7, and between the conical barrel 2 and the lower hollow cone 8.
