Description

[Detailed Description of the Invention] This invention relates to a foldable arm type pest control machine that is used for spraying chemical solutions such as insecticidal and weeding, watering, etc., and is mainly used by being attached to a tractor.

Conventional pest control machines have relatively short distribution pipes with spray nozzles, so the spray area is small.

In order to increase the spray area, it is possible to use a long distribution pipe, but if the long distribution pipe extends left and right, it will not be able to pass through if there is an obstacle.

Of course, if the liquid distribution pipe is left hanging out, it will not be possible to pass on the road.

Therefore, long distribution pipes are installed upon arrival at the farmland, but this work requires considerable effort, and if there are standing trees or other objects in the farmland, they must be removed each time, which is extremely inconvenient and extremely It was inefficient.

In view of this, the present proposal provides a pest control machine that does not have the above-mentioned inconveniences.A liquid distribution pipe is attached to a foldable arm, and the machine can be automatically folded by operating it from, for example, a tractor.
Its distinctive feature is that it can be expanded.

Next, the present invention will be described by way of examples with reference to the drawings.

FIG. 1 schematically shows the pest control machine according to the present invention in a side view.

FIG. 2 schematically shows a perspective view illustrating the folding and unfolding operation of the pest control machine according to the present invention.

FIG. 3 is a front view showing a part of the pest control machine according to the present invention in a folded state, and FIG. 4 is an enlarged front view showing the connecting portion of the first and second arms.

First arms 2, 2 whose bases are pivotally mounted near both left and right ends of the frame 1 are raised and lowered by hydraulic cylinders 3, 3 installed between them and the frame 1, respectively.

When the first arms 2, 2 are in an upright state, they are pivoted so that they are inclined at an angle of, for example, about 45 to 60 degrees in the rear direction of the frame 1 (tractor forward direction), and when the first arms 2, 2 are laid down to the left and right sides. It is positioned horizontally by a stopper (not shown).

Pressure may be supplied to the hydraulic cylinders 3, 3 by pumping the chemical liquid in the chemical tank 5 on the frame 1 using the pump 4, but it is also possible to pump water in a separately provided tank 6 or oil in place of this. You may also do so.

Alternatively, air pressure may be used.

In this case, measures may be taken such as replacing the hydraulic cylinders 3, 3 with pneumatic cylinders, replacing the pump 4 with a compressor, and further replacing the tank 6 with an accumulator.

At the tips of the first arms 2, 2, a shaft 7 whose axis is vertically oriented when the first arms are horizontally expanded and laid down is rotatably supported.

The shaft 7 is a shaft fixed to the base of the second arms 8, 8, and the second arm 8 rotates together with this shaft 7.

A pinion 9 is fixed to the upper end of the shaft 7.

This pinion 9 is meshed with a rack 12 connected to the tip of a rod 11 of a hydraulic cylinder 10 (or pneumatic cylinder) supported on the first arm 2, and the rack 12 is moved back and forth along the first arm 2. This causes the second arm 8 to perform an operation in the folding or unfolding direction.

On the other hand, liquid distribution pipes 13 and 14 are attached to the first arm 2 and the second arm 8 at positions along the lower side of each arm when these arms are respectively expanded.

One end of the liquid distribution pipe 13 attached to the first arm 2 is connected to the pump 4 via a flexible pipe 15, and the other end is connected to the flexible pipe 1.
6 to the liquid distribution pipe 13 of the second arm 8.

A large number of spray nozzles 17 which can freely spray downward are attached to each liquid distribution pipe 13, 14 at predetermined intervals.

Since the present invention has the above-mentioned structure, when the hydraulic cylinder 3 is operated from the state shown by the solid line in FIGS. 2 and 3 and the first arm 2 is laterally collapsed, the first arm 2 and the second arm are
Arm 8 is also laid down horizontally.

Subsequently, when the hydraulic cylinder 10 is operated and the rack 12 is moved from the tip of the first arm 2 toward the base, the pinion 9 meshed with the rack 12 is rotated, and the pinion 9 is fixed. The second arm 8, which is integral with the shaft 7, is rotated horizontally and unfolded, and when it is rotated by 180 degrees, the first arm 2 and the second arm 8 are almost in a straight line, and the second arm 8 is attached to both arms. The liquid distribution pipes 13 and 14 are laid out horizontally and horizontally.

In this state, the tractor equipped with the pest control machine of the present invention is moved while spraying the chemical solution used for killing insects and weeding.

If there is an obstacle in the path during work, the hydraulic cylinder 10 is operated in the opposite direction to fold the second arm 8.

If the vehicle still cannot pass through this, the hydraulic cylinder 3 is operated to raise the first arm 2 and fold it onto the frame 1 before proceeding.

When driving on the road, in a village, in a city, or in a garage, it is best to fold it up.

qI+ All of the above operations are performed by operating the pump 4 and hydraulic cylinders 3 and 10 from above the tractor.

Note that the discharge pressure from the pump 4 is controlled by the hydraulic cylinders 3 and 1.
0, the return circuit is connected to the chemical tank 5 or to the return circuit of the pump 4.

Furthermore, when the structure is such that the chemical solution is force-fed from the pump 4 to the liquid distribution pipe 13 via the flexible pipe 15, a solenoid valve (not shown) is provided to switch between supply pressure to the hydraulic cylinders 3 and 10 and dispersion. Set it up.

Therefore, the pest control machine of this invention can be mounted on a tractor and go to a work site, such as cultivated land, and when it arrives at the site, it can be deployed and the spraying work can be started immediately.

If there is an obstacle while moving, it is possible to pass by folding only the second arm or both the second arm and the first arm, and these operations can be performed remotely from the tractor, making it highly efficient and labor-saving. Excellent effects can be obtained by performing spraying and watering work.
