Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an agricultural machine used mainly in orchards.

Generally, when cultivating fruit trees, it is necessary to dig trenches to a predetermined depth and cut the roots of the fruit trees in order to fertilize the fruit trees or turn the cultivated land upside down.

By the way, when performing the trench digging work and root cutting work, conventionally, special machines such as trenchers and chain saws have been used, and these have to be used separately, which not only increases the purchase cost but also requires the storage of each dedicated machine. It is difficult to manage. Furthermore, in orchards, there are times when it is convenient to perform trench digging and root cutting at the same time; for example, when digging trenches around fruit trees to fertilize them, it is possible to directly dig trenches with a trencher. If this is done, the roots of the fruit tree will get in the way, so in such cases it would be convenient if the root cutting and trenching could be done at the same time, but conventionally, both root cutting and trenching were done. It is impossible to carry out these operations at the same time; it is necessary to first cut the roots and then dig the trench, and both operations require a great deal of labor and time.

The present invention has been made based on the above-mentioned viewpoints, and is equipped with a trencher and a chain saw, and can use any one as required, and can also be used simultaneously with the trencher and chain saw. The purpose is to provide agricultural machinery suitable for various types of work in orchards and the like.

More specifically, a trencher is provided in the fuselage, chain saws are provided on both sides of the trencher, and the trencher and both chain saws are configured to be able to be retracted from a working position to a storage position separately. It is something.

The present invention will be explained below with reference to embodiments of the drawings.

In the figure, reference numeral 1 denotes the body of an agricultural machine, in which an engine 2 is mounted on the upper front part, a transmission case 3 that extends vertically is supported at the rear part, and running wheels 4 are mounted on both sides of the lower part of the case 3. , the transmission case 3 is connected to the wheel 4 from the engine 2.
The transmission mechanism inside is designed to transmit power, and a control handle 5 is provided on the upper part of the case 3 so as to be able to rotate forward and backward of the body 1.

A first transmission case 6 is supported at the center of the rear end of the case 3 so as to be able to swing up and down, and trenchers 7, 7 having bucket conveyors 7a, 7a are pivotally supported on both sides of the lower part of the case 6. At the same time, the transmission mechanism in the transmission case 3 connects the first case 6 and each trencher 7, 7 via a clutch.
The rotary power is transmitted to the bucket conveyors 7a, 7a to carry out the trench digging work by the rotation of the bucket conveyors 7a, 7a. are connected by a support rod 9 with a turnbuckle 8 interposed between them, and the support rod 9 maintains the posture of each trencher 7, 7 constant during trenching work, and the turnbuckle 8 supports By adjusting the extension and contraction of the rod 9, the lower part of each of the trenchers 7, 7 can be swung, and the inclined posture of each trencher 7, 7 can be adjusted during trenching work.

Second and third transmission cases 1 are disposed on both sides of the first case 6 at the rear end of the transmission case 3.
0, 11 are supported so as to be able to swing up and down, and a large number of root cutting blades 12a, 12 are provided at the bottom of each case 10, 11.
The chain saws 12, 12 which are arranged around the transmission case 3 are rotatably supported, and are rotated from the transmission mechanism in the transmission case 3 to the second and third cases 10, 11 and each chain saw 12, 12 via a clutch. While transmitting power and performing root cutting work by rotating each of the root cutting blades 12a, 12a, there is a gap between an upper part of each of the chain saws 12, 12 and both sides of the rear end of the transmission case 3. Connecting rod 13,
13, and the connecting rods 13, 13 are used to maintain a constant posture of each chain saw 12, 12 during root cutting work.

In addition, the first, second and third cases 6, 10,
11 and the machine body 1, a lifting device (not shown) is interposed, and each trencher 7, 7 and each chain saw 12, 12 can be moved up and down, that is, into a storage position and a working position.

In the figure, reference numeral 14 denotes a rear fuselage in the shape of a rectangular frame, which is connected to a hitch fitting 15 provided at the rear end of the fuselage 1, and a grounding ring 1 is provided at the center of the rear end of the rear fuselage 14.
6 is supported.

In the embodiment described above, there are two
Although two trenchers 7, 7 are provided, only one trencher 7 may be provided.

In addition, the first, second and third cases 6, 10,
11 is removably attached to the transmission case 3, and the trencher 7 and chain saw 1
2 may be made detachable as desired, and in this case, the agricultural machine can be used for tasks other than trench digging and root cutting, increasing the versatility of the agricultural machine.

The agricultural machine of the present invention is constructed as described above, and when performing trench digging work in an orchard, etc., each chain saw 12 is retracted to the upper storage position as shown by the imaginary line in FIG. While cutting off the power to the chain saw 12, the trencher 7 is placed in the lower working position, and the power is transmitted to the trencher 7 by operating the clutch, and the machine body 1 is moved forward or backward while cutting the trench. The trench digging work is carried out by the driller 7.

When cutting the roots of fruit trees, etc., the trencher 7 is evacuated to the upper storage position as shown by the phantom line in FIG. 3, the power to the trencher 7 is cut off, and the chain saw 12 is moved downward It is lowered to the working position, power is transmitted to the chain saw 12, and as the machine body 1 advances, the chain saw 12 performs root cutting work.

Furthermore, when fertilizing fruit trees and digging trenches around the fruit trees, the trencher 7 and chain saw 12 are lowered to the working position as shown by the solid line in Figure 1, and power is applied to both. At the same time, the roots of the fruit tree are cut by the chain saw 12, and the trencher 7 is used to perform trench digging work.When doing this, the roots of the fruit tree do not get in the way, and the trencher 7 cuts the roots of the fruit tree with ease and precision. This allows for trench digging work.

Note that the agricultural machine of the present invention can be used not only in orchards but also in general fields.

As explained above, the agricultural machine of the present invention includes a trencher and a chain saw in the machine body, and the trencher and chain saw can be evacuated separately from the working position to the storage position. The trenching work and the root cutting work can be done separately or both at the same time, so there is no need to prepare two specialized machines such as a trencher and chain saw for fruit tree cultivation, etc., and the purchase cost is low. Not only is it convenient to manage. In addition, in the present invention, both trench digging work and root cutting work can be performed at the same time, so when trench digging work is performed around the fruit tree in order to fertilize the fruit tree, in particular, while cutting the root of the fruit tree with the chain saw, This allows trench digging work to be done accurately, easily, and in a short amount of time.
