Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spraying device in a management work machine for spraying a herbicide, a pesticide such as a herbicide, an insecticide, or a pesticide, which is made of granular material such as granular fertilizer or seeds, or powder.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, there is already known a sprayer in which a sprayer including a fan with a tank is mounted at the center of the rear part of a management work machine, and the sprayer is constantly swung to spray particles or powder.

[0003]

[Problems to be solved by the device]

 The above-mentioned known spreader can increase the spread width, but since the spray pipe mounted on the vertical axis is constantly swirling, the drive device becomes large and the spray density in the lateral direction is not uniform. There was a problem such as becoming. Therefore, we installed a spray pipe that protruded laterally from the center of the machine width so that the granules could be sprayed over the entire width by making one round trip in the field. However, it was difficult to align the areas when the aircraft was traveling, as well as when they were close to each other or overlapped with each other and a part of the field was significantly damaged. In addition, if the field width is more or less than an integral multiple of the spray width, or if the spray width changes due to wind, or if the same spray pipe is used to spray herbicide or other pesticide powders When the width becomes narrow, a double-spray part occurs, and in order to eliminate this, it was necessary to perform a troublesome operation such as closing some of the injection ports.

[0004]

[Means for Solving the Problems]

 According to the present invention, a sprayer in which a tank is attached to a blower is mounted on a machine base of a management machine having a traveling device, a spray pipe is connected to a discharge port of the blower, and the spray pipe is located from the center of the machine body. The above-mentioned problem was solved by mounting the support device on a horizontally swivel support device disposed in a position deviated toward one side, and connecting the support device to a rotary drive device in an interlocking manner.

[0005]

[Action]

 When applying fertilizer by spraying granular fertilizer, the machine is placed at one end of the field and directed in the longitudinal direction, and the spray pipe is run with the swivel fulcrum extended to the side that is offset. When the spreader is driven, the granular fertilizer in the tank can be pressure-fed by the blower and sprayed from the discharge port of the spray pipe to the half width on the other side of the field. When the aircraft was turned 360 degrees to the part where fertilization was completed on the headland after one stroke was finished, the spray pipe was deviated to the side where the fertilizer was run in the first stroke, so the spray pipe was not applied immediately. Since it faces the ground, the next spraying work can be performed with a simple turning operation. Further, when a dust such as a herbicide is sprayed back and forth similarly to the above-mentioned granules, the spraying width is narrower than that of the granules, so that in the above field, the unsprayed portion remains by the width of one step. Therefore, when the spray pipe is swung 180 degrees and the machine body is run in the opposite direction to the already-sprayed part in the unsprayed part, the swivel fulcrum is deviated to the side opposite to the swung side. Can be spread over the entire unsprayed area.

Of the brackets 7a, 7a protruding from both sides of the rear part of the machine base 7 attached to the connecting frame 4, the extension base 8 is detachably connected to the one on the right side when viewed from the rear. Reference numeral 9 denotes a pair of left and right large tanks.

The sprayer 14 attached to the machine base 7 is composed of a tank 10 having a shutter 11 at a lower portion and a blower 12 connected to the lower portion of the tank 10, and an engine 13 is connected to a rear portion of the blower 12 in an interlocking manner. On the extension base 8, a vertical turning shaft 16 having a receiving metal 15 at the upper end is rotatably inserted into and supported by a support cylinder 17, and is provided at the discharge port of the blower 12 and at the lower surface. A sprinkling pipe 20 in which a large number of sprinkling ports 19, ... The holding metal fitting 21 integrated with is fitted and attached, the lower side of the holding metal fitting 21 is connected to the receiving metal 15 by the pivot 22, and the long hole 23 of the metal receiving 15 and the round hole of the holding metal fitting 21 are bolted. By inserting 25, the inclination angle The small sprocket 27 of the output shaft of the small motor 26 that rotates forward and backward and is screwed so that it can be adjusted is a large sprocket attached to the lower part of the revolving shaft 16. Since it is linked to 28 via a chain, when the above small motor 26 is normally or reversely rotated, the spray pipe 20 is rotated 180 degrees forward and backward with the swivel shaft 16 as the center.

A shutter opening / closing motor 30 is linked to the shutter 11 and a throttle motor 31 is linked to the engine 13 described above. These motors 26, 30, 31 are shown in the control diagram. As described above, when the shutter opening / closing position potentiometer 33 of the input device 32, the forward / reverse switch, etc. are input to the microcomputer 35, the control output thereof activates the relays of the driver 36 and the relay box 37, respectively, and the swivel range of the spray tube 20 is changed. The pair of limit switches 38 and 39 limits the horizontal direction to 180 degrees.

Although the above-mentioned spraying device is not limited in use depending on the field area or shape, for example, the field to be worked has a width of 30 m and a length of 100 m, and the spraying pipe 20 is made of a granular fertilizer or the like. Explaining a spraying example when it is possible to spray the granular material in a width of 15 m, the riding management machine 1 is put in from the center of the left side of the field and 3 to 4 m from the end of the field (width equivalent to headland). ) Move it to stop, operate the switch for turning on the operation panel in the operation section to turn to the left, and operate the input setting tools such as the shutter open / close position potentiometer 33 and the setting dial of the throttle motor 31. 10 causes the spray pipe 20 to take the posture shown by the chain line in FIG. 10, the engine 13 starts up to a predetermined rotation speed, the shutter 11 opens, and the particles in the tank 10 are removed. The air is blown into the spray pipe 20 by the blower 12 and is sprayed from the spray ports 19 ... to the field A ₁ , so that when the airframe is backed in this state, it is sprayed to the edge of A ₁ . Next, the spray pipe 20 is swung to the right and projected as shown by the solid line in FIG. 10, and the machine body is moved forward to spray A ₂ having a width of the right half of the field. When spraying one stroke is Tsu Owa, closing the shutter 11, without the low-speed rotation of the engine 13, is Kaigyo the fuselage at headland, toward the District ₃ A as indicated by a chain line in the sparge tube is pivoted 180 degrees Kawase one Dan was sprayed to ₃ ° a is moved forward, then back body, spraying the spray tube 20 to a ₄ district by 180 was wound Do旋advanced directs the a ₄ ° as indicated by the solid line Suru

In the method shown in FIG. 12, when the spray pipe 20 is positioned along the rear surface of the machine body and reaches the corner of the field without rotating, the machine body is sequentially rotated by 90 degrees to A₁ , A₂ , A₃ , A_Four Disperse in order.

Further, when the width of the field is different from the above size and the final spraying stroke width is narrower than a predetermined width, or when the last unsprayed width becomes narrow due to the influence of wind or the like, the spraying pipe 20 is set. This can be dealt with by setting the spray amount per unit area constant by setting it inclining to the traveling direction and adjusting the engine speed to reduce the pumping amount. Further, as shown in FIG. 13, when the cap 20b with the guide 20a is fitted into the distal end opening of the spray pipe 20, the spray width can be limited to be approximately equal to or slightly wider than the distance between the rear wheels. The input device may be a receiver for a transmitter, and remote control may be performed by outputting a control signal to the control device of the passenger management machine in addition to the above control by the microcomputer 35.
