Grain scraper
Technical field
The utility model relates to a kind of grain feedway, particularly a kind of grain scraper.
Background technology
Grain scraper is widely used in the transhipment entrucking of grain depot grain in bulk, the grain charging entrucking in bulk and the Bulk Grain of rice processing factory irritated bag etc.Existing grain scraper has wing wheel formula, spiral, grilled teeth formula structure, wherein wing wheel formula structure be by two counterrotating wing wheels with cereal by being fixed on framework soleplate (or being shovel board) scraping delivery below the wing wheel to load-transfer device, being delivered to the equipment discharging opening by load-transfer device finishes the work, there are the following problems for this wing wheel formula structure: 1, because scraper plate and base plate gap are very little, cereal is stuck between scraper plate and the base plate easily, it is broken to cause cereal to be blocked, and reduces economic benefit; 2, to be blocked the wing wheel consumed power that causes rotation easily bigger owing to cereal, so the energy consumption height; 3, owing to fibre-bearing foreign material in the cereal are more, easily the fiber foreign material are involved in the wing wheel axle during wing wheel rotation, the time one is long, cause that easily the wing wheel transport efficiency is low and increase motor load or burn out motor, 4, complete machine heaviness, complex structure need to adopt electric walking, and maintenance is inconvenient.
Sped structure is made up of conveyor screw and shell, and there are the following problems for this sped structure: 1, the conveyor screw opposite shell is made sliding friction, and is easily that the cereal card is broken and reduce economic benefit, and conveyor screw is short service life; 2, helical feed efficient is low, and relative power consumption is also bigger; 3, it is less to take off the paddy scope.4, there is not dust collector.Do not meet the environmental health requirement.
The valley head of taking off in the grilled teeth formula structure is to make circular movement by rake teeth cereal is taken off to load-transfer device, is transported to the equipment discharging opening by load-transfer device and finishes the work, and there are the following problems for this grilled teeth formula structure: be rake teeth owing to taking off material mechanism 1,, efficient own is low; 2, because rake teeth is made circular movement and also easily the fiber in the cereal is involved in rake teeth or the rotating shaft, cause transport efficiency low; 3, complete machine heaviness, lift adjustment, mobile all inconvenient; 4, do not have dust collector, do not meet the environmental health requirement.
Summary of the invention
Technical problem to be solved in the utility model is in order to overcome above-mentioned weak point of the prior art, increases broken fewly and provide a kind of, and energy consumption is low, the efficient height, and long service life, easy to maintenance taken off paddy and is carried and irritate the bag bin discharger at operation.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
