Grain device is received on a kind of adjustable threshing ground
Technical field
The invention belongs to agricultural machinery equipment field, be specifically related to a kind of adjustable threshing ground and receive grain device.
Background technology
Grain-production is always in occupation of the main status of China, during the busy farming season, peasant household is by after grain harvest, in order to remove the moisture in grain, prevent grain because going bad containing excess moisture and mildew, people are always spread out in grain on threshing ground and carry out airing, after drying, manual collection loads grain sack (namely with spade or scoop usually, manual by crops collection), it is large that its problem brought is not only labour intensity, and it is very low to receive grain efficiency.When running into sudden change weather, may, because having little time to collect grain, grain be caused to be drenched with rain.Along with the development of mechanization of agriculture, receive grain efficiency to threshing ground to have higher requirement, and existing receipts grain device is all adopt large tractor to drive, receive grain efficiency poor, complex operation, large to the particle damage rate of grain, be difficult to widely use, therefore, letter a kind of novel adjustable to be studied light receipts grain device.At present, grain device is received without the threshing ground of adjustable portable in market, and this device is simple to operation, can regulate the car body speed of travel, receive grain efficiency high according to the airing thickness of grain, and grain is received on the threshing ground being applicable to middle-size and small-size peasant household.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, provide a kind of applied widely, and the adjustable threshing ground of the car body speed of travel can be regulated to receive grain device according to the airing thickness of grain, alleviate hand labor intensity, realize high efficiency and receive grain.
In order to achieve the above object, the technical solution used in the present invention is: provide a kind of adjustable threshing ground to receive grain device, comprise car body, header board, round brush, pit, helical conveyer mechanism, inhale grain device, turbine and worm, drive motor, power supply, control unit etc.According to the thickness of airing grain, the rotating speed of motor is regulated to control the speed of advance of car body by control unit.On the header board making grain be stacked into when car body travels forward to be arranged on car body front end, then roll to take off to the grain being stacked into header board by round brush and be transported to pit, then by spiral conveyor rod, grain is transported to lower grain tube, reclaims into grain sack.Inhale the rear side that grain device is arranged on car body, produce negative pressure by air pump and carry out secondary collection to leaking the grain received, the grain of collection enters grain sack by lower grain tube.
Concrete scheme of the present invention is: header board is arranged on the front end of car body, makes grain be stacked on header board when car body travels forward, and header board can regulate the gap with ground according to state of ground by built-in mechanism voluntarily, and header board and state of ground are adapted.The turning cylinder of round brush is connected in the bearing seat of car body front end by bearing, is used for rolling the grain be stacked on header board taking off pit.One end of screw rod cover is connected by screw on pit, and the other end is bolted on the vehicle frame of car body, and spiral pipe box tilts 48 degree to be arranged on the centre of car body.Screw rod one end is connected in the bearing seat of pit by cylindrical roller bearing two, and the other end is connected in the bearing seat of screw rod cover by bearing.The screw-internal thread fit of turbo-shaft one end and screw rod, the other end is connected in the bearing seat of turbine and worm casing by cylindrical roller bearing one.Turbine is connected on turbo-shaft by key, and engages each other with worm screw.Worm screw is arranged in the bearing seat of turbine and worm casing, and air pump is arranged on the top of collection tanker, and collection tanker is bolted on car body, and crop inlet pipe is connected by screw on collection tanker.Lower grain tube is bolted on spiral tube cover, and its lower surface is parallel to the sweep face of car body.Gu bag frame is bolted on the sweep of car body, and be positioned at the below of lower grain tube, can firm grain sack, prevent grain sack from toppling over and grain is trickled down.Rear wheel is connected to the both sides of back axle by bearing.Enter grain plate to be bolted on lower grain tube, and parallel with car body sweep face; Entering grain plate is oblong-shaped platy structure, and its surface uniform distributes 150 circular ports, larger than the maximum gauge of collected grain 3 millimeters of the diameter of circular port.Motor provides electric energy by power supply, and power supply and motor are bolted on the sweep of car body.Belt wheel one is arranged on the output shaft of motor, and belt wheel two is arranged on the centre of front axle by wedge key, and belt wheel one is connected by belt two with belt wheel two, can realize the driving to car body.Front vehicle wheel and rear wheel are arranged on the both sides of car front axle and car rear axle respectively, for the walking of car body.Pit is bolted on the side arm of car body.Sprocket wheel one is connected on the axle of round brush by key, and sprocket wheel one is connected by chain with sprocket wheel two, can realize the driving to round brush.Belt wheel three is arranged on the output shaft of motor, and belt wheel four is arranged on one end of worm screw, and belt wheel three is connected by belt one with belt wheel four.Gear two by key connection on the rotating shaft, and engages each other with the gear one be arranged on motor output shaft.Turning cylinder is connected in the bearing seat of steady pedestal by bearing, and steady pedestal is bolted on car body.Control unit is connected by screw on the sweep of car body, and its rotating speed be mainly used to by controlling motor controls the speed of advance of car body.Handlebar is connected on car body.Turbine and worm casing is bolted on the vehicle frame of car body.One end and the front hyoplastron of connecting rod one are connected through the hinge, and the other end and connecting rod two are connected through the hinge.Side panel is connected by screw on back incline, trickles down when preventing grain from being rolled take off by round brush to both sides.Connecting rod two be enclosed within spring bores, connecting rod two is adjustable length expansion link, by the gap on hyoplastron and ground before the adjustable in length that changes connecting rod two.Spring is placed in spring card slot, and spring card slot is connected by screw on the side panels.Front hyoplastron and back incline are connected through the hinge, and front hyoplastron adopts the manufacture of elastic recovery material.
The invention has the beneficial effects as follows: when the present invention adopts car body to travel forward, grain is stacked into and is arranged on the header board of car body front end, then by round brush grain rolled and take off pit, then use screw rod to carry grain, improve the efficiency of grain collecting.Header board can regulate the gap with ground according to state of ground by built-in mechanism voluntarily, header board and state of ground is adapted, ensure that the granule integrity of grain, decrease in the face of the abrasion factor of header board.Use the transmission devices such as turbine and worm can realize larger transmitting ratio, ensure the power needed for mechanism.The suction grain device that car body rear is installed can carry out secondary collection to leaking the grain received, and ensure that grain can be collected cleaner.Driven the motion of car body by motor, alleviate the labour intensity of user, reach time saving and energy saving.This device is simple to operation, low cost of manufacture, can be widely used in and collect corn, Chinese sorghum, wheat, bean or pea and paddy etc., be applicable to middle-size and small-size peasant household.
