Abstract

The invention relates to the field of grain scrapers, in particular to automatic production equipment used for grain ex-warehousing and loading. The automatic production equipment comprises a traveling gear, a grain scraping device, a delivery mechanism, a grain outlet and a control device. The grain scraper adopts a screw shaft for grain scraping, thereby solving the technical problem that moving parts are easily wound; the grain scraper can automatically stop when encountering barriers, thereby improving safety of the operation; the traveling gear is of vehicle structure, thereby realizing automatic traveling of the grain scraper; front-tooth tires are adopted, thereby solving the technical problem that the grain scraper easily slips when moving on a smooth ground or a ground with grains; the delivery mechanism is made into a shape of a seal groove, thereby reducing dust and noise pollution; the grain outlet can rotate, thereby facilitating mating of the grain scraper and equipments like vehicles, barns and the like. With high comprehensive performance, experiments show that the grain scraper can scrape 120t of grains per hour during actual use, with efficiency far higher than that of the grain scrapers in the prior art.

Description

A kind of grain scraper

Technical field

The present invention relates to the grain scraper field, specifically is a kind of automated production equipment that is used for grain outbound, entrucking.

Background technology

Grain be the mankind survived basic, Chinese population has accounted for 1/5th of world population, the importance of grain is especially remarkable.But the grain-production power of China is but not strong, and a peasant of the U.S. can manage up to a hundred mu of farmlands, and the production of Chinese farmers mainly can only be satisfied family's needs, and its basic reason is that production facilities falls behind.Domestic grain scraper mainly can be divided into three classes at present: scrape template, wing wheel type and spiral vertical-type, as the disclosed a kind of scraper plate of No. 01248715.5 patent of China Patent No., spiral compound type grain scraper, disclose and scraped template and two kinds of structures of spiral vertical-type; As No. 200720076329.1 disclosed winged wheel scrapers of patent of China Patent No., wing wheel type structure is disclosed.Three types all have a following defective:

One, movable parts is wound easily, and is difficult to trouble-shooting.The movable parts of machine burns out motor after being twined by foreign material easily.

Two, noise is big.

Three, degree of automation is low, and walking is inconvenient.

Four, yield poorly.Per hour take off about 50 tons of grain.

Summary of the invention

The technical problem to be solved in the present invention is the shortcoming at prior art, and the degree of automation of the problem that the solution movable parts is wound easily, the noise that reduces machine, raising machine provides a kind of Combination property higher grain scraper.

In order to solve above technical matters, grain scraper of the present invention comprises running gear, grain-pushing equipment, feedway, put out cereal mouth, control setup.

Running gear is used for mobile grain scraper, forms vehicle structure by four wheels, motor and bearing circle comprising two molar drive wheels, by the motor-driven running gear, and the direction of bearing circle control walking; Feedway is used to transmit grain, comprises motor, belt and barrel-contoured enclosed slot, and belt is installed in the enclosed slot by motor-driven; Grain-pushing equipment is used for grain is taken off the belt of feedway, comprises motor and screw shaft, and screw shaft is provided with two sections opposite helicallobes of direction, and the horizontal front end that is contained in grain-pushing equipment of screw shaft is rotated by motor-driven; The mouth of putting out cereal is used for grain is imported vehicle from feedway, is the pipeline of bending, by electric machine control around the wherein axis rotation of a segment pipe of an end; Control setup is used to control running, the speed of each motor, is the decision circuit that comprises relay.

Control setup is fixed on the running gear; Feedway tilts to be fixed on the running gear; The lower end of feedway makes screw shaft parallel with strap surface and vertical with the belt movement direction with the grain-pushing equipment butt joint, between feedway and the grain-pushing equipment for being hinged, be provided with switch between the two, switch disconnects when lifting grain-pushing equipment, and whole motors of grain scraper all shut down; The upper end of feedway is docked with the mouth of putting out cereal and is made that grain can be from the feedway mouth of putting out cereal of flowing through smoothly.

The screw shaft of grain scraper of the present invention is provided with two sections opposite helicallobes of direction, the horizontal front end that is contained in grain-pushing equipment of screw shaft, grain is overstock toward the centre by helicallobe backward when screw shaft rotates, and grain can be taken off on the belt, has solved the technical matters that movable parts is wound.For being hinged, be provided with switch between the two between feedway and the grain-pushing equipment, switch disconnects when lifting grain-pushing equipment, and whole motors of grain scraper all shut down, and can stop automatically when grain scraper runs into obstacle, have improved the safety of operation.Running gear is a vehicle structure, adopts auto manufacturing technology to realize the automatic walking of grain scraper; And adopt the molar drive wheel, solved grain scraper smooth or the technical matters that motion is skidded easily on the ground of grain arranged.Feedway is made the shape of seal groove, has prevented that grain from stirring the dust that produces in the process and wafing into aerial, and has reduced noise greatly.The mouth of putting out cereal can rotate, and has made things convenient for coordinative composition of equipments such as grain scraper and vehicle, silo.Grain scraper of the present invention is because the Combination property height, per hour can take off 120 tons in grain when the experiment proved that actual use, and efficiency far is higher than the prior art grain scraper.

Further specify technical solution of the present invention below in conjunction with the drawings and the specific embodiments.
