The present invention relates to a farm machinery having an air compressor function, and more particularly to a farm machinery having an air compressor function capable of producing compressed air using the power of the farm machinery.

In general, tractors, combines, cultivators and the like are mechanical devices used for agriculture, and are provided with an internal combustion engine to generate a constant power. And such a farm machinery has its own unique functions, it is difficult to use other machinery.

And an air compressor is a device which produces the compressed air by the compressor installed inside, using the motor which generate | occur | produces a rotating power by electricity as a drive source. Since the structure of such an air compressor itself is already known, detailed description thereof will be omitted. The air compressor drives the internal compressor by using the rotational force of the motor, and substantially compresses the air with the compressor built in the compressor head by using the rotational power.

Since a general compressor uses a motor as a drive source as described above, it is pointed out that a disadvantage cannot be used in a place where electricity cannot be supplied. In addition, air compressors are generally used for many purposes in farming and fishing villages, and in particular, they cannot be used in places where electricity is not supplied, which causes many inconveniences in the use of air compressors.

Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

First, the agricultural machinery used in the present specification means a device that is used for agriculture, such as a tractor, combine, cultivator, etc., and generates power by an internal combustion engine. Moreover, since it is mainly used for agriculture, it is comprised so that it can move substantially, and it is comprised so that a movement is possible by transmitting internal engine power to a wheel.

Next, a description will be made based on FIGS. 1 and 2. 1 shows an embodiment in which the apparatus according to the present invention is implemented in a tiller which is one of agricultural machinery. 2 shows an overall schematic configuration of the apparatus according to the present invention. First, as shown in FIG. 1, the drive pulley 10 is provided in the output shaft 2 of the tiller.

The output shaft 2 is an output shaft provided outward from the cultivator body in order to drive a rotary unit mounted in the cultivator. As described above, in the present invention, it is a basic technical idea to drive an air compressor by using an output shaft installed to extract the output from the farm machinery.

This output shaft means an axis for driving a rotary in a tiller, a main axis in a combine, and a PTO axis in a tractor. As described above, the agricultural machinery in the present specification is defined as meaning a cultivator, combine, and a tractor, and further, the output shaft means an axis installed in the apparatus so that the output can be pulled out from the agricultural machinery. It is defined as.

As can be seen with reference to FIG. 2, the drive pulley 10 installed on the output shaft 2 transmits power to the electromagnetic clutch 14 through the belt 12, and thus the electromagnetic clutch 14. Rotated). In addition, the rotation shaft 13 of the electromagnetic clutch 14 is substantially connected to the inside of the compressor head 20, and is configured to operate the compressor component inside the compressor head 20 by the rotation thereof. As is well known, the compressor head 20 has a compressor component for compressing air by rotating by a conventional motor. In addition, it can be seen that the rotation shaft 13 of the electronic clutch 14 performs substantially the same function as the rotation shaft of the conventional motor.

In addition, the electronic clutch 14 itself is currently known and rotates by receiving power from the driving pulley 10 through the belt 12, and is controlled by turning on / off the power supplied. That is, the electronic clutch 14 is provided with a structure that transmits or cuts off power by supply of power. Therefore, when power is supplied to the electromagnetic clutch 14, the internal clutch is turned on so that the rotational power in the driving pulley 10 can be transmitted to the rotation shaft 13 of the clutch. In addition, when the supply of power to the electromagnetic clutch 14 is stopped, the state is turned off, and even if the driving pulley 10 rotates, the electromagnetic clutch 14 itself is idle, and the rotational force of the driving pulley 10 is rotated. Will not be delivered.

By the control of the electromagnetic clutch 14 as described above, the rotating shaft 13 performs the rotation. When the rotary shaft 13 is rotated, it operates the compression component inside the compressor head 20, thereby substantially compressing air.

Air compressed in this way is introduced into the compression tank 30 through the connection hose (22). The compression tank 30 is for storing compressed air at a constant pressure, and the pressure of the stored air is preset. In addition, a pressure gauge 34 capable of measuring such a pressure is provided, and when a pressure exceeding a predetermined pressure is applied, a safety valve 32 capable of discharging air to the outside is preferably installed.

And the compression tank 30, the pressure gauge 34 or the pressure sensor is installed, the signal measured in this is transmitted to the switch 40. For example, assuming that the internal pressure is set to 7Kg / cm ² , when the pressure inside the compression tank 30 reaches this, the electrical signal from the pressure gauge 34 or a separate pressure sensor is switched Is passed to 40. The signal transmitted in this way is transmitted back to the electromagnetic clutch 14 so that the electronic clutch 14 is substantially controlled to idle, so that no further air compression occurs in the compressor head 20.

In the present invention, the power source required for the switch 40 or the electromagnetic clutch 14 uses a battery of an agricultural machinery. That is, the reference numeral Ca in FIG. 2 is a wiring connecting the switch 40 and the battery of the agricultural machinery, and the reference numeral Cb is a wiring connecting the electronic clutch 14 in the switch 40. to be. Therefore, it can be seen that the power source from the battery of the agricultural machinery is configured to control the electronic clutch 14 via the switch 40.

According to the present invention as described above, it can be seen that the basic technical idea is to drive the air compressor using the output shaft of agricultural machinery such as cultivator, tractor and combine. Many other variations are possible to those skilled in the art within the scope of the basic technical spirit of the present invention as described above.

For example, the transmission of power from the output shaft 2 of the agricultural machinery to the electromagnetic clutch 14 is configured to be transmitted through the belt driving method in the above-described embodiment, but the transmission of the power to the electromagnetic clutch, For example, it is also possible to implement through other power transmission devices such as power transmission using gears or power transmission using sprockets and chains.

According to the present invention as described above it can be expected the following effects.

Conventional air compressors can not be driven without electricity, according to the present invention is configured to drive the air compressor using a farm machinery such as tractors, tillers and combines. Therefore, there is an advantage in that the air compressor can be driven even in a place where electricity is not supplied, and it is expected to be convenient for use in various applications.
