Description
Technical field
The utility model belongs to processing of farm products field, is specifically related to a kind of paddy winnowing machine.
Background technology
Current rural households formula produces that the paddy winnowing machine used comprises air compartment, is arranged on the fan of air compartment one end, motor, be arranged on grain outlet bottom air compartment and feeding warehouse, motor is connected with fan by power output shaft, is provided with feeding-passage between air compartment and feeding warehouse.Feeding-passage is provided with a switch, two gears are only opened and closed to this switch, in time needing to process some impurity many paddy, these impurity can be stuck in inside feeding-passage, in order to these impurity are removed, usually stab toward feeding-passage to make impurity come off inside feeding warehouse with rod, if paddy pending inside feeding warehouse is many, rod cannot stab feeding-passage, or needs pending paddy to remove, or toward feeding-passage stamp inside air compartment.Therefore, for making peasant simple and easy to do when carrying out selection by winnowing work to paddy, a feeding adjustment mechanism must be set on the feeding-passage of existing paddy winnowing machine, this feeding adjustment mechanism not only has the function of switch, also want the flow that can regulate feeding-passage, run into the paddy that impurity is more, then flow is increased.It is cheap that rural households' formula produces the paddy winnowing machine price comparison used, and price, usually below 1000 yuan, so when the feeding adjustment mechanism of design paddy winnowing machine, must consider the problem of cost.Secondly, existing rural households formula is produced the paddy winnowing machine used and is only had a grain outlet, time impurity is more, usually needs the grain exporting out by grain to carry out secondary selection by winnowing, adds peasant work amount, waste electric energy.3rd, existing rural households formula is produced the paddy winnowing machine used and is produced wind-force by the rotation of driven by motor fan, when running into rural area power failure, then cannot work.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of paddy winnowing machine, and feeding-passage is provided with feeding adjustment mechanism, to adapt to the more paddy selection by winnowing work of impurity, this feeding adjustment mechanism cost is lower, meets the purchase requirement that rural households' formula is produced.Its technical scheme is:
A kind of paddy winnowing machine, comprise air compartment, be arranged on the fan of air compartment one end, motor, be arranged on the grain outlet bottom air compartment and feeding warehouse, motor is connected with fan by power output shaft, feeding-passage is provided with between air compartment and feeding warehouse, it is characterized in that: also comprise feeding adjustment mechanism, described feeding adjustment mechanism arranges on feeding-passage, feeding adjustment mechanism comprises door, rotating shaft, retainer ring and spring, door is fixedly connected with one end of rotating shaft, the other end of rotating shaft is socketed with rotary sleeve, rotary sleeve has bottom, rotating shaft and rotary sleeve pass through spline joint, the end face of rotary sleeve is connected by contrate gear pair with paddy winnowing machine shell, a face gear of contrate gear pair is fixedly connected with paddy winnowing machine shell, another face gear of contrate gear pair is fixedly connected with the end face of rotary sleeve, rotating shaft is hollow structure, interior of rotating shaft is provided with spring, one end of spring connects the bottom of rotary sleeve, the other end of spring connects paddy winnowing machine casing.
When not operating feeding adjustment mechanism, due to the pulling force of spring, the face gear of rotary sleeve end face engages with the face gear on paddy winnowing machine casing; Because the face gear on paddy winnowing machine casing is fixedly connected with paddy winnowing machine casing, therefore rotary sleeve can not rotate.Because rotary sleeve can not rotate, make can not rotate with the rotating shaft of rotary sleeve by spline joint, and then fix door.When needs operate feeding adjustment mechanism time, first pull outward rotary sleeve, the face gear of rotary sleeve end face is separated with the face gear on paddy winnowing machine casing, and then rotate rotary sleeve, because rotary sleeve and rotating shaft pass through spline joint, driven rotary axle rotates by the rotation of rotary sleeve, and then door is rotated.After door is rotated to suitable position, decontrol rotary sleeve, rotary sleeve to the motion of paddy winnowing machine, finally makes the face gear of rotary sleeve end face engage because of the pulling force of spring with the face gear on paddy winnowing machine casing.
Further, described grain outlet comprises the first grain outlet and the outlet of the second grain, and the first grain outlet is arranged on immediately below feeding-passage, and the second grain outlet is arranged between the first grain outlet and air outlet.If treat that the paddy impurity of selection by winnowing is many; part impurity and paddy kernel can enter the second grain outlet; and the first grain exports out is clean grain; only need the impurity of the second grain outlet and paddy to carry out second time selection by winnowing just passable, instead of all materials exporting out from grain all will be needed to carry out second time selection by winnowing.
Baffle plate is provided with between first grain outlet and the second grain export.Arranging of this baffle plate can prevent the grain of the first grain outlet too many and overflow in the second grain outlet.
Baffle plate is provided with between second grain outlet and air outlet.The arranging of this baffle plate can prevent grain to be blown out because of sweeping along of impurity air outlet.
Described paddy winnowing machine also comprises footstep mechanism, footstep mechanism comprises the first gear pair, power transmission shaft and the second gear pair, the power output shaft of motor is connected with the second gear pair, second gear pair is connected with the first gear pair by power transmission shaft, and a gear of the first gear pair is provided with pedal.When power failure or when treating that the paddy of selection by winnowing is less, fan can be started by foot-operated mode.
