Description

Power thresher

Technical field:

The utility model and paddy, the sheller unit that the ripe plant of wheat is adopted is relevant.

Background technology:

Existing paddy, wheat thresher, the power set of employing are two kinds of oil-burning machine and electromotor, and the body of oil-burning machine is big, oil price cost height; the rotating speed of electromotor is fixed, and is when power source voltage fluctuates, little when big during the power of motor output; normally threshing, the threshing weak effect.Used power supply is an AC network, wiring inconvenience, and poor stability uses limited by infrastructure.

The utility model content:

The purpose of this utility model provides a kind of applied widely, and outputting power is stable, power thresher simple in structure, with low cost.

The utility model is achieved in that

The utility model power thresher; axle 1 is connected with threshing barrel 2; the two ends of axle 1 are connected with bearing 3 respectively; bearing 3 is connected with bearing block 5 on the support 4; axle 1 is in transmission connection with the power take-off of direct current generator 6, and direct current generator 6 is connected with two outputs of motor speed controller 7, and two inputs of motor speed controller 7 are connected with the positive and negative electrode of accumulator 8 respectively; the control end of motor speed controller 7 is connected with speed switch 9, and speed switch 9 has magnetometric sensor.

Two inputs of motor speed controller 7 are parallel with voltmeter 10.

Motor speed controller 7, speed switch 9 are positioned on the front apron 12 that is connected with support 4, and direct current generator 6 and accumulator 8 are positioned on the support 4.

Adjustable speed Hall element 16 is housed in the housing 15 of speed switch 9 to be connected with the control end of motor speed controller 7, slider bar 17 two ends are fixed with the opposite magnet of magnetic pole 18, adjustable speed Hall element 16 is between two magnet 18, and slider bar 17 is slidingly matched with the chute of housing 15, and handle 19 is arranged.

Axle is fixed with driven pulley 13 on 1, is connected with drive pulley 15 on the motor power output shaft by belt 14.

The utility model adopts accumulator jar as power supply, use the restriction that is not subjected to infrastructure, do not rely on AC network, wide accommodation can be widely used in high mountain and knob, use cost is low, security performance is good, and direct current generator is controlled rotating speed by motor speed controller, can not influence rotating speed because of accumulator jar output voltage reduction in use, threshing is effective, the threshing steady quality.The utility model is simple in structure, and volume is light and handy, and cost of manufacture is low.

Description of drawings:

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

Fig. 3 is the speed switch structure chart.

Embodiment:

Adopt charger that the 220V power for illumination of family expenses is charged to 8 li on accumulator, be converted to dc source, on the panel of the front apron 12 of thresher, establish power switch, voltmeter, motor speed controller 7, speed switch 9.Establish a direct current motor 6 and accumulator 8 on the support 4 of thresher, they interconnect the electricity consumption bundle of lines mutually, have formed the power set of thresher with belt pulley 13,15.

Accumulator is the accumulator jar that 12V, 22V, 38V, 48V do not wait.

The direct current generator size is the motor that 12V/300W, 22V/300W, 38V/400W, 48V/600W do not wait.

They can be suitable for thresher size and decide, and this is that the sheller unit of power can not constitute safety in the electricity consumption to the person with the dc source, makes the work of thresher proper motion with motor speed controller, charges and once can work a few hours, and cost is very cheap.

Thresher is made up of threshing barrel 2, axle 1, bearing 3, bearing block 5, support 4 and front apron 12.

Find out the output voltage of accumulator 8 from the reading of voltmeter 10, adjust motor speeds by speed switch 9 according to this output voltage.

Speed switch can be the speed switch that uses on washing machine or the electric fan, and motor speed controller can be the rotating speed control chip that uses on washing machine or the electric fan.

There is adjustable speed Hall element 16 to be positioned at the magnetic field that the opposite magnet 18 of two magnetic poles on the slider bar forms in the housing of speed switch 9, move with slider bar 17 in this magnetic field, and Hall element 16 is exported the control end of different signals to motor speed controller 7 as sensor.The output of motor speed controller 7 is connected with direct current generator 6, and input is connected with accumulator 8, can move the handle 19 of slider bar 17 according to the reading of voltmeter 10.
