An exemplary embodiment of the present invention will be described as follows.

In configuring the operation type wide-area agricultural complex spreader, the tractor used as an agricultural implement removes the existing wheels and ancillary equipment and uses only the power source as the power main body (10).

Here, the power body 10 having a power source may be separately manufactured and implemented, but the use of the tractor, which is supplied to most farms in Korea, as the power body 10 is aimed at reducing the cost, and the for dissemination and use.

The above-described power body 10 has a narrow and thin width and a relatively large circumference of the present invention, which has been developed for easy adaptation to the Korean terrain and easy movement in the field where crops are grown. ) is mounted on the formed wheel (60).

The wheel 60 of the present invention is configured to have a narrow width so that it is convenient to move between crops previously planted, thereby protecting the crops without hurting them.

And by increasing the diameter of the wheel, it is convenient to climb up and down in the multi-level type of agricultural land in Korea. In addition, by forming a “L”-shaped friction protrusion on the outer circumferential surface of the wheel (60) to enhance the frictional force to scrape in the rotational direction, it is possible to ride on a stone. To make it easier when crossing over or climbing a paddy field.

In addition, the tire was made as small as a wagon wheel to eliminate the tube for injecting air and made of an elastic material so that there is no fear of malfunction due to a puncture.

Next, a description will be given of the main frame 20 for configuring the agricultural complex spreader, which is the main part of the present invention. The main frame 20 of the present invention comprises a coupling portion 25 on the front side, which is coupled to the lifting rod 11, the end of which is lifted and lowered by the operation of the hydraulic cylinder, on the back side of the power body 10, made it possible to escape.

Such a main frame 20 constitutes the machine mounting unit 21 and the medicament barrel mounting unit 22 and the spraying means mounting unit 23 .

The machine mounting unit 21 of the main frame 20 configured as described above includes a power transmission means, a blower means, a transmission cooling means, a liquid pressure transmission means, and an operation intermittent means.

Here, the blowing means includes the power output from the power body 10 and the CV joint 12 connected to the primary transmission 30 to accelerate the rotational speed, and the shifted power from the primary transmission 30 . A primary electric shaft 31 that transmits a driving force and is equipped with a pulley 32, a secondary high-speed transmission 35 connected to the primary electric shaft 31 for acceleration, and the secondary high-speed transmission 35 It consists of a blower fan 40 in which a fan rotating with an accelerated driving force is mounted.

Here, the use of the blowing fan 40, which is a blowing means, as a centrifugal pump is because it is easy to generate a large amount of air at a relatively high output.

At this time, by installing the cover 15 that covers the lower side of the CV joint 12 connected to the engine of the power body 10 and the lower side of the machine mounting part 21 of the main frame 20, the cultivated crops are A crop protection means is configured so as not to be damaged by being wound around the CV joint 12 or the primary electric shaft 31 and the pulley 32 accumulating therein.

The belt 53 used at this time may use any of a V-belt, a timing belt, a chain, and a flat belt, but it is ok to use a V-belt or a timing belt that has no noise while ensuring power transmission.

And the transmission cooling means installs the secondary high-speed transmission 35 adjacent to the blowing fan 40 so as to follow the shaft hole 41 of the secondary high-speed transmission 35 and the blowing fan 40 from the blowing fan 40. A part of the generated air is injected toward the rotational shaft of the secondary high-speed transmission 35, and at the same time, a part of the air generated from the blower fan 40 is guided to the air inducer 45 to the housing of the secondary high-speed transmission 35.

At this time, the air inducer 45 may be configured to be injected into the secondary high-speed transmission 35 by inducing the blower fan 40 from the outlet side to the pipe.

The reason for cooling the secondary high-speed transmission 35 as described above is that the service life is short if the heat generated by the gear for high-speed shifting is not cooled.

Finally, the operation interception means for selectively stopping the operation of the high-pressure plunger pump 50, which is a liquid pressure transmission means, is, The pulley 32 accumulated on the primary electric shaft 31 is configured to be connected by hooking the pulley 52 accumulated on the crankshaft of the high-pressure plunger pump 50 constituting the liquid pressure feeding means with the belt 53 .

At this time, one side of the table 55 on which the high-pressure plunger pump 50 is installed is constituted by a hinge 56, and the other free end is screwed to the screw bar 57 for rotating operation with the handle 58. As the table 55 is tilted by the rotation of the screw bar 57, the position of the high-pressure plunger pump 50 installed on the table 55 is changed, and power is transmitted or blocked by adjusting the tension of the belt 53.

In this way, selectively blocking the operation of the high-pressure plunger pump 50 means that the high-pressure plunger pump ( 50), there is no reason to operate.

The present invention configured in this way stores the drug to be sprayed in the drug container 70, moves to the spraying site, and operates the handle 58 to turn the screw bar 57 to raise the table 55 when the drug is liquid. Tighten the belt 53 so that the high-pressure plunger pump 50 operates, and when the drug is granular or powder, loosen the belt 53 so that the high-pressure plunger pump 50 stops operation, and then the power body 10 When the engine of 32) by driving the pulley 50 condensed on the crankshaft of the high-pressure plunger pump 50 connected to the belt 53, the liquid drug stored in the medicament container is the spraying cloth 80 installed in the spraying means mounting part 23. It is fed under high pressure with a nozzle mounted inside (not shown because it is a known technique),

In addition, the driving force of the primary electric shaft 31 is transmitted to the secondary high-speed transmission 35 and accelerated to a high speed, and the fan of the blowing fan 40 connected to the secondary high-speed transmission 35 rotates at high speed to generate strong wind. The liquid agent is sprayed while flying over a long distance while being pumped and discharged by pressure with the spray cloth 80 .

When the drug is granular or powder, operate the handle 58 to turn the screw bar 57 to lower the table 55 to loosen the belt 53, select so that the high-pressure plunger pump 50 stops operation, and then select the drug container (70) When the powder outlet formed at the bottom (the detailed description is omitted because it is already known in my prior invention) is opened and the drug flows into the spray bag 80, the strong wind generated by the blower fan 40 is generated from the spray bag. (80) will be compressed and sprayed.

At this time, in the secondary high-speed transmission 35 installed adjacent to the blowing fan 40 , a part of the air generated by the blowing fan 40 is discharged along the shaft hole 41 of the blowing fan 40 , so that the secondary high-speed transmission 35 . At the same time to be injected toward the rotational shaft of the transmission 35, a portion of the air generated by the blower fan 40 is injected into the housing of the secondary high-speed transmission 35 through the air induction device 45 to the secondary high-speed transmission 35 ), and the spraying cloth 80 performs the spraying operation while changing the spraying direction to the left and right according to the user's operation.
