Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a sprayer that sprays a chemical solution toward left and right crops while running between crops in which management machines are planted in rows.

[0002]

[Prior Art]

 The spraying of chemicals when cultivating crops in rows in a normal field or greenhouse was carried out by a backpack-type power sprayer, a duster, or a manual pest controller. A control robot equipped with an engine, pump, and injection pipe has already been proposed.

[0003]

[Problems to be solved by the device]

 In all of the backpack type, the spray pipe is manually operated, so that the medicine can be sprayed to the back side of the crop, but the weight of the sprayer is entirely loaded on the human body, which is extremely hard work. In addition, although the remote control type is easy to work on, the spray tube was fixed to the machine frame, so it was difficult to spray the drug on the back side of the leaves of the crop, and the work precision was low.

[0004]

[Means for Solving the Problems]

 The present invention relates to a management machine in which an engine is mounted on a machine frame having wheels, and a pump driven by the engine, a tank connected to the pump, and a pair of left and right spray pipes for spraying a chemical solution pumped by the pump to a crop in the machine frame. The above-mentioned problem was solved by connecting the injection pipes to the drive device so that the injection pipes can be moved up and down and forward and backward.

[0005]

[Action]

 When the traveling device, the pump, and the injection pipe are driven by the engine, the pump inhales the drug in the tank and pumps it to the injection pipe, and the pumped drug is sprayed from the nozzles of the left and right injection pipes toward the crop. At this time, the spray pipe moves back and forth and up and down, so that the leaves of the crop sway in each direction, which allows spraying to the back side of the leaves.

[0006]

【Example】

 The present invention will be described with reference to a spreader that also functions as a point-applying fertilizer applicator shown in the drawings. It consists of a pair of left and right wheels 5 and 5 that are driven, a pair of left and right auxiliary wheels 6 and 6 that are pivotally supported so that the lower part of the main frame 1 spreads out, and a handle 7 that stands up diagonally rearward. At the rear part of the engine 3, a pump 10 having a suction port connected to an upper tank 8 through a suction hose 9 is mounted, and a column 11 standing upright on the front part of the main frame 1 is directed to both left and right sides. The horizontally extending frame 12 is fixed, and a pair of left and right chain cases 13, 13 are attached to both sides of the horizontal frame 12 so as to form a V shape when viewed from the front-rear direction, and the upper portions are connected to each other. Between the bottom of 3 and The other end of the crank arm 17 ... With both ends of the horizontal shafts 15 and 16 erected between the parts connected to the upper and lower sprockets via universal joints, and one end attached to each end of the horizontal shafts 15 and 16. The upper part and the middle part of the fertilizer application pipes 20, 20 having the nozzle 18 at the lower end are rotatably connected to each other.

When the management machine described above is used as a fertilizer applicator, paste fertilizer or liquid fertilizer is put in the tank 8, and the horizontal shaft 16 below the pump 10 and the speed reducer and the chains 21 and 22 is driven by the engine 3. When the sprocket in the middle part of the pump is driven, the pump 10 sucks the fertilizer in the tank 8 and discharges it to the distributor 23, and the fertilizer pipes 20 and 20 are rotated by the crank arms 17 ... It moves back and forth while moving up and down along the inclination direction, and also moves left and right, and while the fertilizer application pipes 20 and 20 stick out on the ground and move out, they move backwards in synchronism with the running speed, so it is possible to move laterally. The fertilizer is pierced into the ridges, and at that time, the dispenser 23 dispenses the fertilizer into the fertilizer pipes 20 and 20 through the hoses 25 and 25 for a certain period of time to apply the fertilizer to the soil in spots. Inclining the fertilizer pipes 20, 20 in this manner does not damage the branches of the fruit trees that are planted in rows and bulged to the left and right like in an orchard.

A spray pipe 27 is attached to each of the fertilizer application pipes 20, 20 via stays 26, 26 so as to be vertical or inclined so as to follow the shape of the crop. , 27 are provided with a plurality of nozzles 27a, ... which are directed to the outer side at intervals in the vertical direction, and the middle part is connected to the discharge port of the pump 10 through a hose 28 bypassing the distributor 23 and a switching valve. Since the hose 28 is connected to the pump 10 by the switching valve because it is connected, the pump 10 continuously pumps the drug solution contained in the tank 8, and the injection pipes 27, 27 are in a fixed mounting posture. While being held, the chemicals pumped while moving up and down, front and back, and left and right as shown in the figure are sprayed from the nozzles 27a ... toward the crops in the greenhouse or on the ridges in the field, whereby the leaves of the crops are sprayed. Shakes up and down, left and right Since it moves, it is possible to spray the drug on the back side of the leaves. In addition, in the above-described embodiment, the injection pipe 20 is also moved in the left-right direction, but the same action and effect can be obtained by moving the injection pipe 20 only in the front-rear direction. If the chemical spray pump and tank are separate from the fertilizer application system, it is possible to perform chemical spray and spot fertilization in the same process.

[Effect of the device]

 The present invention relates to a management machine in which an engine 3 is mounted on a machine frame having wheels, and a pump 10 driven by the engine 3 and a tank 8 connected to the pump 10 and a chemical solution pumped by the pump 10 are sprayed onto a crop. Since a pair of left and right injection pipes 27 are mounted, and these injection pipes 27 are interlocked and connected so as to move up and down and front and back, when the injection pipe 27 is driven by the pump 10 and the drive device while the management machine is running. , The spray pipe 27 moves up and down and front and back to inject the chemical liquid pumped by the pump 10 toward the crops cultivated on the row, whereby the leaves of the crop sway greatly up and down and back and forth. Only by running the management machine, it is possible to spray to the back side of the leaves of the crop and achieve high-level spraying. Moreover, the spraying work can be easily performed.
