Description

Boom sprayer for the ride manager.

The present invention relates to a boom sprayer for a passenger manager, and more specifically, a boom that is installed on both sides of a boom sprayer side boom installed for chemical spraying in front of the passenger manager to double the efficiency of spraying. The provision of a sprayer.

Passenger managers allow the operator to perform various types of tasks such as rotary work, control work, transplanting work, restoring work, coating work, transport work, composting and fertilizer spraying with a single machine. Unlike walking type managers that operate the manager while walking, the worker is to board the manager and perform various tasks while driving the manager.

In order to perform the control operation in the above-mentioned riding manager, the foldable boom sprayer is mounted at the front of the riding manager and the chemical tank is installed at the rear so that the control operation can be performed while the boom of the boom sprayer is unfolded.

As described above, the ride manager equipped with the boom sprayer enables the work in the paddy field where the tall crops such as rice or the cultivated short crops are grown by varying the size of the wheels.

Conventionally, such a boom sprayer is composed of an intermediate boom which is supplied with a chemical solution from the chemical tank and fixed on a frame located in front of the passenger transporter, and a side boom which is foldable from both ends of the intermediate boom to the rear. If not, the side boom is folded and fixed to the side of the ride manager, and when the work is configured to expand the side boom to perform the control work.

However, when the side boom is unfolded, the total length of the boom sprayer is only 8 to 10M, which causes considerable difficulty in controlling the rice planted rice fields.

This is because most of the arable land is 30 to 40M and the length is 90 to 100M. Therefore, during the maintenance work, the passenger manager reciprocates in the lengthwise direction of the road, so the number of round trips increases, which reduces the efficiency of the control work.

In addition, Korea is mainly arranging the land in 900 pyeong units, and the width of the discussion is 30M. Therefore, if it is controlled at 10M width, it is 3 times. Therefore, the control is completed on the opposite side of the doorway. Not only is the efficiency lowered, but also the reciprocating more and more times, causing the damage of the rice by the passenger manager, the area where the drug is redistributed is increased, causing unnecessary waste of the drug.

The present invention has been made in order to solve the problems as described above to install an extension boom on the side boom of the boom sprayer installed in front of the passenger manager to perform a more efficient and efficient control work It is done.
