Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a field drilling device that automatically drills deep vertical holes with a depth of 30 to 6 (approximately 1 m and a hole diameter of approximately 3 cnL) in a scattered state C2 in the soil of a field such as a paddy field.

Here, the vertical holes are bored because they improve irrigation and drainage functions and encourage the growth of rice, etc.

The present invention will now be described with reference to the accompanying drawings.

This device includes a machine frame (2) connected to a traveling machine body (1),
The machine frame (2) C2 can be freely moved up and down (2 elevating bodies (2)
3).

a hydraulic mechanism (4) that repeatedly moves the elevating body (3) up and down;
A perforated body (5) attached to the elevating body (3), a perforated body moving mechanism (6) that allows the perforated body (5) to be moved in the longitudinal direction C2 of the traveling body (1), and more. It is what it is.

This example will be explained.

The traveling body (1) of this embodiment is a four-wheeled tractor.

In addition, the machine frame (2) has a three-point link type connection mechanism (7), namely, lower links (8) at the lower left and right, swing arms (9) at the left and right, and lifting arms (1G, at the upper part at the center). Links (connected by LD).

Further, the elevating bodies (3) are arranged so as to be movable up and down on both left and right sides (=2) of the machine frame (2) by a pair of upper and lower guide rollers α2 at the rear of the machine frame (2).

In addition, the hydraulic mechanism (4) of this embodiment repeatedly pushes and pulls and slides.
The machine frame (2), which is the base of the hydraulic cylinder a3, is pivotally connected to the front mounting part, and the fulcrum shaft α1 is mounted on the upper part of the front part of the machine frame (2). The front end of the operating arm (16) is pivotally connected to the tip of the intermediate link (15), and the rear end of the operating arm (16) is connected to the elevating body (3) (two pivots). connecting and operating arm (16
The rod part of the hydraulic cylinder ←■ is pivotally connected to the middle part of 1, and this hydraulic cylinder α3 and the power extraction shaft αr) (:
This is a book that is made by piping a hydraulic motor that rotates more.

Therefore, by the repeated pushing and pulling of the hydraulic cylinder (L3), the operating arm moves up and down through the intermediate link acJ with the fulcrum axis α as the fulcrum.

In addition, the hydraulic cylinder C13, the operating arm tte, etc. are arranged for each elevating body (3), and the elevating body (3) is 480i
Therefore, the elevating body (3) alternately penetrates and withdraws from C and C, and the force is relaxed as much as possible.

In addition, the structure of the hydraulic cylinder α is
) Applicable to those that are linked to repeated push and pull, or those that have a structure that repeatedly pushes and pulls on their own using only hydraulic pressure, such as the hydraulic pump Iwatsuki.

The perforated body moving mechanism (6) of this embodiment is arranged so that the elevating body (3)
The bottom surface (a certain inner frame with a two-section construction shape in the front and rear horizontal direction (= fixed), and this guide frame (1'l (a moving frame with a two-section U shape (2)
The rear C spring sweep of this movable frame is provided with a protruding plate (2), and this spring bolt is connected to the front of the guide frame (to) with the plate (2). part and ζ2 return spring (
C) is suspended, and a stopper rubber is interposed between the front inner surface of the guide frame 9 and the front surface of the movable frame (A), so that the movable frame can be freely moved back and forth.

Further, the perforated body (5) of this embodiment is the lower part (
Two attached rubber elastic stands (251 are attached hanging down).

In addition, the shape of the perforated body (5) is formed into a curved plate with a planar cross section and a cU-shaped soil introduction plate (A), and the lower edge has a sharp edge (2'0). and stone veneer (
C) is formed.

Reference numeral (29) is a vertical hole drilled.

Since this embodiment has the above configuration, the power output shaft α of the traveling body (1) is rotated to rotate the hydraulic motor cod, and the operating lever of the hydraulic motor is operated to supply pressure oil to the hydraulic cylinder α. When supplied, the rod section repeatedly pushes and pulls and slides, and due to the operation of this rod section, the actuating arm tte moves up and down with the fulcrum axis I as the fulcrum via the intermediate link α4, and the movement of the actuating arm ζ: from The perforator (5) penetrates into the soil C2,
C2 is linked to the repeated lifting and lowering of the rear pull-out, and when the traveling machine (1) moves forward in this state, the perforating body (5) goes into the soil (2) When it is drilling, C2 is a moving frame and Q is It moves backwards, and when the boring body (5) comes out, it captures and lifts the soil, and as a result (two vertical holes (c) are bored, and when the boring body (5) comes out of the soil, it is ready for return). Spring (C) (2) moves the moving frame (4) to the front position, and from this action C2, the vertical holes c!l are sequentially drilled in scattered state C:.

Although the number of perforated bodies (5) in this embodiment is two, it is also possible to use a plurality of perforated bodies (5).As described above, the present invention has one traveling machine (1) (two machine frames (2) and , the machine frame (2)≦2 A lifting body (3) arranged to be able to move up and down freely, a hydraulic mechanism (4) that repeatedly moves the lifting body (3) up and down, and the lifting body (3) (2). Since the installed perforated body (5) and the perforated body moving mechanism (6) which can move the perforated body (5) in the longitudinal direction (bi-polar movement) of the traveling body (1), the traveling body (1) ) can be operated using hydraulic pressure (1) (4) (2), so that the perforating body (5) can move up and down repeatedly, and the perforating body (5) (2) can perforate the field. 6) enables continuous well drilling, which not only improves work efficiency, but also enables reliable and smooth drilling work to a predetermined depth in a scattered manner.

At this time, special (= hydraulic mechanism (4) (2) elevating body (3)
This mechanism (=
Therefore, the elevating body (3) moves strongly and reliably, so that the perforating body (5) can efficiently penetrate and withdraw from the soil.

In addition, the mechanical mechanism can be of a simple structure, reducing costs and being advantageous in terms of maintenance.

As described above, the intended purpose can be fully achieved.
