Abstract
The invention discloses a crop air screening device which comprises a support, a feed hopper and the like. A drive wheel drives a driven wheel. An air partition is disposed below a switch. When blades operate, air return to a windmill screen can be stopped to increase air force, and full grains can be separated from blighted grains effectively. Electric drive is achieved through a motor to increase screening efficiency. Six blades are reduced into four blades to reduce size of the windmill screen. The size of the air screening device, the windmill screen and the blades are reduced proportionally, space in the windmill screen is fully utilized, and floor space of the whole device is reduced. The crop air screening device is simple in structure, safe and practical, and the problems that traditional crop air screening devices are large in size, high in material amount for machining, and inconvenient to carry and operate.
Description
Technical field
The present invention relates to a kind of crops air blast, be particularly useful for crops such as paddy, corn, soya bean, wheat and rapeseed.
Background technology
Crops wind cleaning device is mainly used in screening cereal, and full grain and not plump paddy are separated.Though present existing wooden agricultural windmill can play wind to crops and act on only, has problems.Existing agricultural windmill total length is 180 centimetres to 200 centimetres, highly is 150 centimetres to 170 centimetres, and weight is 40 kilograms to 50 kilograms.It is bulky, heavy, the processing materials are many, carrying inconvenience, and two people could operate during use, the waste labour.Wind drum diameter is 120 centimetres, and main body is by the wind drum major part that accounted for.Six pectinid leaves are arranged, make rocking handle by bow type bar bending straight cutting driving shaft, wind acanthus leaf is thick and heavy, and operation is painstaking.Improved irony windmill is arranged at present, its smaller volume, easy operating.But because making body frame with iron pipe, be shrouding with the iron plate, increase cost, very easily get rusty simultaneously, service life is short, is not suitable for the rural area and promotes the use of.
Have much about crops wind cleaning device at present, be the utility model patent of " a kind of main frame of agricultural windmill " as: Granted publication number for the title of CN 2566948Y, comprise the bellows of bringing the hopper interface into, the fan blade rotating shaft that is used for installing fan blade, also comprise for driving motor transmission mechanism that the fan blade rotating shaft rotates, being used for the shifting fork mechanism of avoiding charging to stop up, the driving lever that drives the shifting fork mechanism motion.These other parts of utility model main frame and windmill are separated, though can reduce labour intensity, complete machine volume comparatively speaking is still very big, the total passing inconvenience.
Granted publication number is the utility model patent of " a kind of agricultural windmill of regulating wind-force " for the title of CN 2042756U, changed the locus that aerofoil goes out in the air port by regulating backstay, with size and the wind direction of control air outlet, thereby reach the purpose of regulating wind-force.But owing to adopt manual operations, and operation inconvenience, labour intensity is big.
When the utility model patent that Granted publication number is called " electronic agricultural windmill " for the name of CN 201120376Y is machine operation, the wind-force direction that the fan blade rotation produces is opposite with motor, the covering of having avoided motor to consider to be worth doing because of slag is generated heat impaired, improves mechanical efficiency, reduces energy loss.But complex structure, Granted publication number is called the utility model patent of " electronic, manual agricultural windmill " for the name of CN 2289885Y, be characterized in laying on the windmill base support motor and motor stepless time adjustment switch, fan blade driving-belt on the motor moving runner drives fan blade, fan blade is rotated, play the anti-dandruff effect of airborne dust; Fly driving wheel drives the hopper manipulator and moves up and down by the bent axle driving-belt, finishes material returned process, opens the water valve on the water filling organ pipe, and sparge pipe is sprayed water downwards, carries out depositing dust.But it is bulky, complex structure, and the processing materials are many, and production cost is higher.
Above crops wind cleaning device ubiquity bulky, heavy, and the processing materials are many, carrying inconvenience, less, the unhandy shortcoming of wind-force.
Summary of the invention
Be to solve the prior art above shortcomings, the invention provides a kind ofly for the crops screening plant, solve that crops wind cleaning device of the prior art is bulky, the processing materials are many, carrying and unhandy technical problem.
Technical scheme of the present invention is: crops wind cleaning device comprises support, feed hopper, switch, wind drum, discharging opening, goes out foreign material mouth, air inlet, air outlet, adopt wedge shape to connect between each parts of support, feed hopper is infundibulate, the below is provided with switch, form cavity between support, wind drum, the air outlet, cavity flushes with wind drum opening, discharging opening is arranged near wind drum place, go out the foreign material mouth and be arranged near the air outlet place, four pectinid leaves, driven shaft, driven pulley, driving shaft, driving wheel, rocking handle, wind isolation board, driving-belt are drawn together in described wind bulge; One end of driven shaft is installed a driven pulley, and the other end is installed fan blade; Driving shaft is installed driving wheel, and driving wheel drives driven pulley by driving-belt and rotates, and driven pulley drives fan blade and rotates; Described switch below is provided with a slice wind isolation board; The rocking handle setting is fixed on one side, center of driving wheel.
Described crops wind cleaning device length is 92 centimetres, highly is 105 centimetres; Described air inlet is 14 centimetres, and diameter equates with described air outlet; Described wind drum diameter is 40 centimetres, and width is 27 centimetres, and weight is 17～20 kilograms; 38 centimetres of described fan blade diameters.
End at described driving shaft arranges a runner, is connected with motor by the motor driving-belt; The material of described crops wind cleaning device is wooden.
The present invention is used for crops such as screening paddy, corn, soya bean, wheat and rapeseed.The form that the present invention utilizes driving wheel to drive driven pulley realizes transmission, makes rapid operationization; Wind isolation board is set below switch, when fan blade turns round, can stops wind to be taken back in the wind drum, increase wind-force, can effectively full grain and not plump paddy be separated; Utilize motor to realize Electric Traction, improve the operating efficiency of crops screening; Fan blade reduces to four fans by six fans, makes wind drum volume-diminished, and while wind cleaning device, wind rouse, the fan blade size is all scaled, has taken full advantage of the space in the wind drum, has reduced the shared place of whole device, saves the labour, and is simple in structure, safe and practical.
