Description

Automatic Folding Boom Sprayer

The present invention relates to an automatic folding boom sprayer, and more particularly to an automatic folding boom sprayer that implements a boom pole capable of automatic folding.

In general, the pesticide spraying device which is commonly used in rural areas is equipped with a power sprayer attached to a cultivator, and the power sprayer is operated by the power generated from the prime mover of the tiller so that the pesticide spraying member connected to the power sprayer by the pesticide- As shown in Fig. 3, a conventional agricultural machine is a machine for removing and attaching a frame to the rear half of a tractor, as shown in Fig. 3, which is a machine for spraying pesticides on rice paddies or fields, And working means such as a pesticide barrel, a power sprayer and a hose winder are installed in the frame and the power generated by the prime mover of the tractor is received by the power take-off unit and operated.

The Korean Registered Utility Model No. 20-0286400 (Aug. 30, 2002) discloses a boom sprayer which is detachably mounted on a front frame provided on a front portion of a tractor, and a rear frame, which is detachably attached to a tractor, And a pesticide spraying member are installed to receive the power generated from the prime mover of the tractor by the power take-off unit and to operate the pesticide spraying apparatus. A power take-off portion connected to a prime mover of the tractor for transmitting power to a rear portion of the tractor, a frame provided detachably from a rear portion of the tractor and provided with a power sprayer driven by the power take- A pesticide spraying package having a boom spray, wherein the frame opens the upper part to enclose the pesticide container, forms a seating part in the frame extending to the upper side of the pesticide container rear part, and rotates the pesticide application part And is coupled to a fixing table as much as possible. According to the disclosed technology, it is possible for a person to walk on a sitting portion of a rear frame without running the pesticide spreading member while walking around with the pesticide spreading member in hand, so that the pesticide spraying operation can be performed so that the hose is unwound or wound with the hose winding machine It is possible to reduce the time required for spraying the pesticide on a large area of paddy field or field by moving the pesticide on the tractor at the same time as spraying the pesticide at the same time as well as improving the workability, Bar, breathing is not difficult, and can be released from the year of pesticide by wearing mask.

Korean Patent No. 10-0948694 (Mar. 12, 2010) has a telescopic boom which can be adjusted in length. The boom can be stably extended through the boom support. The sprayer is fixed to the boom, The pesticide can be sprayed onto the cultivated land while being moved along with the agriculture pesticide, and thus the pesticide spraying apparatus having a boom that is easy to spray the pesticide on the large cultivated land is described. According to the disclosed technology, in a pesticide spraying apparatus, a boom which is made of a telescopic type having a plurality of folding bodies and is adapted to be adjustable in length but is extended from a point close to a fixed reference point when unfolded; A boom support which is fixed to the folding body and moved together with the folding body, a boom support which is not fixed to the folding body in a state where the boom is extended to a predetermined length, is seated on the ground to support the boom; A sprayer having nozzles for spraying pesticides and spraying pesticides while moving along the boom while moving together with the boom being adjusted; And an agrochemical supply device having an agrochemical supply hose for supplying agrochemicals stored in the agrochemical storage tank to the sprayer and having a compressing means for compressing the agrochemical supplied so that the agrochemical supplied thereto is injected strongly through the sprayer, And the boom support is adjustable in spacing between a portion fixed to the boom by a hydraulic cylinder positioned between a portion fixed to the boom and a portion contacting the ground and a portion contacting the ground.

The conventional chemical solution dispensing apparatus as described above has a problem that strong force and physical strength are required because a heavy hydraulic hose is required to be dragged by a worker while a strong hydraulic pressure is applied.

In the conventional chemical solution dispensing apparatus as described above, a person must directly carry the hose connected to the hose winder and the agricultural chemical spreading member and directly spray rice paddy while walking on the rice field or the field, so that the hose wound on the hose winding machine is loosened, And the workers had to suck pesticides and suffer pesticide harm.
