Abstract

The utility model relates to a self-rotating and disassembling type grain spread-out machine, which is mainly composed of a fixed axis, a transmission outer sleeve and a grain sliding groove. The fixed axis is installed on the middle part of a grain sliding tube which is arranged on a granary top, and the lower part of the fixed axis is provided with a connecting bearing and the transmission outer sleeve. The top of the transmission outer sleeve is connected with the grain sliding groove which is obliquely arranged in a granary. Both roots of the grain sliding groove are reserved with grain overflow ports. The grain sliding groove is a bent arm which is composed of a long groove and a short groove. Impact force formed by falling grains impacts against an impact angle which is formed by the grain sliding groove to force a groove arm to rotate to uniformly spread fallen grains in a granary along different ring surfaces. The utility model has the advantages of energy saving, superior suitability, grain spreading uniformity, and convenient installation and maintenance, being suitable for continuously loading grains into various shallow round granaries and steel plate granaries in the field of grain granaries.

Description

The detachable grain distributer of rotation type

The utility model relates in a kind of grain depot storehouse goes into the grain distributer that grain is used, and particularly large-scale silo can make grain be evenly distributed on non-power grain distributer in the storehouse when going into grain.

The put in storage grain distributer of usefulness of present domestic grain mainly contains electrodynamic type grain distributer and fixed type equipment for dispersing grains.The electrodynamic type grain distributer is unsuitable for the existing loading of putting in storage continuously as storehouse types such as silo, steel silos, needs all will change on a large scale whole design-calculated equipment absolute altitude and the relevant facility of attaching troops to a unit if use, and as many as the dismounting more again installed; Need cable laying again simultaneously, it is bigger to consume energy, and maintenance load is big, difficult sealing, and power is located at outside the storehouse, and swivel chute is in the storehouse, and is stuck as rotating element, causes motor to burn out easily or entire equipment is scrapped.The fixed type equipment for dispersing grains, cloth grain effect is relatively poor, and the automatic classification phenomenon of grain is among a small circle still arranged, and this classification phenomenon causes intensification easily, goes mouldy, infested, thereby influences the margin f sefety of grain; In addition by manhole warehouse entry maintenance difficulty.

The purpose of this utility model is to overcome many defectives that do not accommodate that above-mentioned grain distributer exists, design a kind of various storehouses, shallow garden and steel silo of being applicable to and unload cloth grain continuously, neither change former technological process, can solve the detachable grain distributer of non-power rotation type of the automatic classification phenomenon of grain again.

Design goal of the present utility model is: destroy the grain landing and the automatic classification phenomenon of generation when grain puts in storage, carry out even cloth storehouse to change from slipping angle, for finishing above-mentioned task, design plan of the present utility model is: grain distributer is mainly by anchor shaft, coupling bearing, the transmission overcoat, collection grain bucket, grain downflow tube and grain-downslide slot constitute, chute is divided into length, the grain-overflowing outlet of short groove and empty setting between the chute root, the grain that enters grain downflow tube and collection grain bucket is dished out along chute (mouth) rotation of three groups of different lengths, form the anchor ring rectangular distribution of three different-diameters when making grain fall in the storehouse, and impulsive force and the grain distributer chute shock angle that form of grain when land by Cang Ding clashed into grain distributer rotated automatically.This grain distributer architectural feature is: anchor shaft is installed in the grain downflow tube middle part of Cang Ding, and coupling bearing and transmission overcoat are equipped with in the anchor shaft bottom; Link with it at transmission overcoat top and grain-downslide slot is arranged in the storehouse, leave grain-overflowing outlet between two grain-downslide slot roots with skewed being distributed on; Grain-downslide slot is designed to have angle of bend, makes the impulsive force of storehouse roof fall grain and grain-downslide slot form the shock angle that can make the grain distributer rotation.

Concrete structure of the present utility model is: grain-downslide slot is the bend arm that the 2-3 group is made up of the length chute, its bend angle β is 90～180 °, grain-downslide slot arm rotative speed is except relevant with angle of bend, also relevant with the flow and the flow velocity of whereabouts grain, can adjust its rotative speed by control grain flow and flow velocity, the inclined angle alpha of grain-downslide slot is designed to 20～40 °.

The grain-downslide slot bottom surface is provided with support, support one end is connected transmission and puts outward, the other end is connected in the crooked position of grain-downslide slot bottom surface by the connection holes on the chute clamp, be removable the connection between grain-downslide slot and the transmission overcoat, promptly by clamp coupling sleeve is fixed on outside grain-downslide slot and the transmission respectively and puts in the junction of grain-downslide slot and transmission overcoat, and fix with gim peg, it is comparatively convenient to adopt detachable connection mode to install, can in the storehouse, assemble, can in a plurality of storehouses, carry out single-piece or complete machine again and exchange, overhaul.

The utility model is compared with existing electrodynamic type and fixed type equipment for dispersing grains has following advantage;

1, rotation automatically so saved propulsion source, neither changes former technological process because the power of this grain distributer comes from the shock angle of storehouse roof fall grain and the formation of grain distributer chute arm, the coupling that can be connected with relevant corollary equipment again, and applicability is good;

2, cloth grain is even, has prevented the automatic classification phenomenon that major diameter Tong storehouse produces when going into grain effectively, is applicable to that various storehouses, shallow garden and steel silo etc. go into grain, loading continuously;

3, assembly and disassembly is convenient, for ease of maintenaince, when the grain that puts in storage surpasses the rotation height, also can make equipment for dispersing grains and use, and does not influence grain and puts in storage.

Be described in detail in conjunction with the specific embodiment of the present utility model below by accompanying drawing.
