Abstract

A power automatic reverse control device of a rice milling and disintegrating combined machine belongs to the field of control devices capable of realizing the automatic reversing of motors in agriculture machinery. The power automatic reverse control device is installed on a rice milling and disintegrating combined machine, wherein a clockwise and an anticlockwise belt sheaves are installed on an output shaft of a motor, and are respectively connected with a rice mill and a disintegrator through triangle belts to control the motor to rotate clockwise and anticlockwise. When the motor rotates clockwise, one device of the combined machine works, and the other device thereof is stopped, when the motor rotates anticlockwise, the working device is oppositely. The power automatic reverse controller is provided with two relays which are respectively connected with the motor through circuits, a three-throw switch connected with an external power supply can provide two paths of control signal sources, one of paths of control signal sources controls one relay to realize the clockwise rotation of one motor, and the other path thereof controls the other relay through a circuit for realizing the anticlockwise rotation of the motor. The power automatic reverse control device has simple structure, convenient operation, safety and reliability.

Description

Unit mahine power automatic reverse controller is pulverized in husk rice

Technical field

The utility model relates to a kind of farm machinery and realizes the auto reversive control device of motor, is specifically related to a kind of husk rice and pulverizes unit mahine power automatic reverse controller.

Background technology

It is the indispensable agricultural processing equipment in rural area that unit mahine is pulverized in husk rice, and two motors of employing that unit mahine is pulverized in existing husk rice to be had drive rice mill and pulverizer respectively, make complex structure like this, needs many repetition parts.In order to change the weak point of using multiple electric motors, be improved to now and adopt a motor to drive rice mill and pulverizer respectively separately, this just needs switching device shifter, this switching device shifter has the employing mechanical type to switch, as the patent No. is that the unit mahine automatic switching control equipment is pulverized in 200420105838.9 husk rice, or adopt the control of mechanical type electrical equipment stacked switch, be that to pulverize unit mahine control device and the patent No. be 200820140586.1 the husk rice pulverizer that automatic reversing apparatus switches that passes through for 200420105837.4 husk rice as the patent No..These devices are combined into one the husk rice pulverizer, though only use a motor, when changing operation function, the existence operation is inconvenient, fault rate is high, the deficiency of poor reliability, and artificial regulatory easily produces operate miss, damages motor, also causes personal injury easily.

The utility model content

Pulverize there is above-mentioned defective in unit mahine when carrying out motor commutation deficiency in order to overcome existing husk rice, the purpose of this utility model is: provide a kind of husk rice to pulverize unit mahine power automatic reverse controller, this power automatic reverse controller architecture is simple, easy to operate, safe and reliable.

The technical scheme that its technical problem that solves the utility model adopts is as follows:

Unit mahine power automatic reverse controller is pulverized in a kind of husk rice, it comprises that motor, two-way relay and three throw change-over switch, described power automatic reverse controller is installed in husk rice and pulverizes on the unit mahine, this power automatic reverse controller is provided with the two-way relay, this two-way relay links to each other with the motor of husk rice pulverizing unit mahine respectively by circuit, three throw change-over switch the two path control signal source is provided by what link to each other with external power supply, relay of the circuit of wherein leading up to control realizes that motor just changes, and another road is controlled another relay by circuit and realized the motor counter-rotating.

Pulverize in husk rice forward and reverse belt pulley are housed on the output shaft of motor of unit mahine, this forward and reverse belt pulley link to each other with pulverizer with rice mill respectively with the V-belt.

Because the utility model power automatic reverse controller is installed in husk rice and pulverizes on the unit mahine, rotating and reverse of control motor, forward and reverse belt pulley are housed on the output shaft of motor, be connected with pulverizer with rice mill with the V-belt respectively: when just changeing, wherein for example rice mill work of equipment, another equipment for example pulverizer stops.During counter-rotating, pulverizer work, rice mill stops.Thereby realize only changing operation function by electric circuit automatic reverse with a motor.

Owing to adopt technique scheme, make the utility model compared with prior art, have following beneficial effect:

1, simple in structure, with low cost

The utility model realizes that the rotating switching of motor relies on electric circuit to realize automatic reverse fully, and electrical equipment and circuit theory are all very simple, make motor automatic reverse controller architecture simple, with low cost, are easy to make, and help suitability for industrialized production.

2, easy to operate

When the utility model carries out power automatic reverse at husk rice pulverizing unit mahine, only need operation three to throw change-over switch and can realize motor commutation, operate very simple and easy to do.

3, safe and reliable

Three of the utility model select tape auto-lock function is thrown change-over switch, when realizing that motor positive and inverse switches is arranged certain blanking time, can improve the reliability of switching.Full electric device of the present utility model is different with the moving rotation of existing armrest stacked switch, and it is short to overcome the stacked switch mechanical contact life-span, easily produces the problem of electric arc, and owing to there is not the machinery action, can improve the security of operation.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the electrical principle schematic diagram that unit mahine power automatic reverse controller is pulverized in the utility model husk rice.

Among the figure, 1. motor, 2,3. relay, 4. three throw change-over switch, 5. unit mahine is pulverized in husk rice.

The specific embodiment

Figure 1 shows that an embodiment of the utility model husk rice pulverizing unit mahine power automatic reverse controller, this power automatic reverse controller is installed in husk rice and pulverizes on the motor 1 of unit mahine 5, controls rotating and reverse of motor.Forward and reverse belt pulley are housed on the output shaft of motor, are connected with pulverizer with rice mill with the V-belt respectively: when just changeing, a for example rice mill job of equipment in the unit mahine, another equipment for example pulverizer stops.During counter-rotating, pulverizer work, rice mill stops.This power automatic reverse controller is provided with the two-way relay, this two-way relay links to each other with motor 1 respectively by circuit, three throw change-over switch 4 the two path control signal source is provided by what link to each other with external power supply, the circuit control relay 2 of wherein leading up to realizes that motor just changes, drive an equipment operation in the husk rice pulverizing unit mahine, the motor counter-rotating is realized by circuit control relay 3 in another road, drives the running that another equipment in the unit mahine is pulverized in husk rice.
