Description

Pesticide sprayer for tractor with double hose reel {AGROCHEMICAL-SPRAYER BY DOUBLE HOSE REEL}

The present invention relates to a pesticide sprayer for a tractor, and in detail, to a pesticide sprayer for a tractor that enables dual spraying, long-distance spraying, fire extinguishing work by dual configuration of the hose reel.

Conventional pesticide sprayer unit is configured to operate the sprayer with one-way power by using a two-way gearbox to power the tractor from the PTO shaft of the tractor, it is configured to wind the hose reel with another one-way power, about 200m in the hose reel The hose is wound and configured to spray within the length of the hose.

Such a pesticide sprayer has a short working radius in view of the fact that the working radius is limited by the length of the hose and the arable land area is increased day by day.

On the other hand, the pesticide sprayer is also used for the purpose of acid fire extinguishing, but in the case of having such a short length of the hose can be sprayed only at close range was limited to use for extinguishing purposes.

The present invention connects the PTO shaft of the tractor and the main shaft of the high-pressure sprayer to drive the sprayer, the pulley shaft is connected to the driven shaft of the sprayer, the two pulleys are coupled to the pulley shaft, and the hose reel mount is symmetrically shaped. By installing two hose reels to be connected to each pulley, spraying or watering can be done simultaneously in two places, and when one hose is completely loosened, it is possible to double the working radius by connecting another hose. It is designed to present a pesticide sprayer for a tractor having a double hose reel of the structure.

Hereinafter, the configuration and operation of the present invention by the accompanying drawings in detail.

Figure 1 is a perspective view showing the basic structure of the present invention, Figure 2 is a plan view of the present invention is a stacking box (1) of the structure in which the three-point link connector (1a) is formed in the front, two parallel rows of loading Two hose reels 3 and 4, which are coupled to support the shafts 3a and 4a on both sides of the upper part of the frame 2, and mounted on the lower frame 2a between the two hose reels. ) Is a high-pressure sprayer (5) connected to the tractor's PTO shaft (20), a pulley shaft (6) connected to the driven shaft (5b) of the high-pressure sprayer, and two pulleys (6a) coupled to the pulley shaft ( 6b) and belts 7 and 8 for connecting the pulleys 3b and 4b coupled to the hose reel shafts 3a and 4a, and the tension of the belts 7 and 8 to adjust the driving force. It consists of a tension control device (9) (10) for stepwise adjustment.

In the above, the frame 2 is installed in the stacking box is configured to be detachably coupled to the stacking box to be used in the form of removing the frame when using the stacking box.

The high pressure sprayer sucks fire water or pesticides from the chemical container (loaded separately in the rear of the loading box), compresses them to high pressure, and supplies them to the hoses wound on the respective hose reels, as shown in FIG. The tractor's PTO shaft 20 is connected to 5a, and the driven shaft 5b is coupled to the pulley shaft 6 so as to be able to wind up each hose.

Each hose reel (3) (4) is to be wound around the hose (11) (12) having a length of approximately 200m, each hose is connected to the outlet of the high-pressure atomizer and the outer end is a pesticide sprayer or It is used in conjunction with the fire water spray nozzle, each hose is coupled by a joint and easily separated, it is possible to connect the two hoses to each other.

Therefore, as shown in FIG. 4A, each hose is connected to the sprayer, and spraying or watering can be simultaneously performed at two places. When one hose is completely released as shown in FIG. 4B, the inner end is separated from the hose reel. By combining with a hose wound on another hose reel, the hose can be extended for a long time, thereby increasing the working radius.

When winding the connected hose, it is possible to wind each hose on two hose reels by winding the hose completely on one hose reel, separating the connection part, connecting the other hose reel, and winding it.

Each tension control device (9) (10) is a tension control pulley on the connecting rod (9b) (10b) angular movement about the axis (9a) (10a) fixed on the frame (2) as shown in FIG. (9c) and (10c) are installed so as to be in contact with each belt (7) (8), and the lower end of the speed control lever (9d) (10d) coupled to the body of the connecting rod and the frame (9e) (10e), the speed control lever is configured to be caught on the transmission plate (9f) (10f) having a multi-speed transmission stage by applying tension to each belt connected in a loose form for each speed change lever of the speed control lever It connects the power required to rotate the hose reel, and has a function to adjust the rotation speed (ie, the speed of winding the hose) according to the degree of tension.

According to the above configuration, the transmission can be made in multiple stages in a state where the power connection is cut off or connected according to the position of the speed control lever applied to the transmission plate.

Therefore, when the hose is not sensed, the power is cut off, and when it is wound, it can be wound at an appropriate speed.

The present invention by the above configuration is used for the fire extinguishing work in the event of spraying or forest fire, etc., it is possible to spray and extinguish at two places by mounting two hose reels, and when one hose is loosened, the other hose Can be used to connect long distance work has the effect.

In addition, by distributing power to the hose reel using the driven shaft of the high pressure sprayer, the power connection is easy, and the high pressure sprayer and the hose reel are mounted on the frame separated from the loading box. Has the effect.
