Description

[Detailed explanation of the idea] The present invention relates to a trench excavator.

In other words, it can be used to dig deep trenches to put compost, etc. in orchards, etc., and is particularly suitable because it can perform soil reliably and smoothly while digging wide trenches with a rotary. It is intended to be provided so that it can be implemented in the future.

The embodiments shown in the drawings will be described below.

Figure 1 is a side view of the whole with some parts removed, and the vehicle A configured as a management work machine has an engine E installed behind a transmission case 7 that has wheels 6, 6 mounted on both sides of the lower part. At the same time, a handle 8 which can be freely changed is extended from the upper part of the transmission case 7.

Reference numeral 1 denotes a rotary case, and the upper part of the rotary case 1 is connected to the mission case 7 side via a hitch 9, and a transmission case 10 is extended from the side of the mission case 7 to the upper side of the rotary case 1. Rotaries 2, 2 are installed on both sides of the lower part of the rotary case 1 so as to match the width of the wheels 6, 6. It is set up and configured.

Further, a rotary frame 11 connected to the upper part of the rotary case 1 is extended forward, and the rotary frame 1
A narrow rotary cover 3 is provided on the lower surface of the rotary cover 1, and soil lifting guide covers 4, 4 are provided on both sides of the cover 3 via hinges 12, 12, respectively, so that the cover is inclined upwardly from the sides. Although the hinges 12, 12 are arranged in series, the hinges 12, 12 may be rotated about an axis to adjust the inclination.

A rectifying plate 5 is attached to the lower surface of the rotary cover 3 which is the front side of the rotary case 1. Both side surfaces 5a of the rectifying plate 5 are formed into slopes so as to be inclined diagonally upward, and both side surfaces 5a , 5a are formed so that their upper extensions are connected to the slope of the soil lifting guide covers 4, 4.

In addition, vertical support rods 13 are inserted from the rotary frame 11 at the ends into the rectifying plate 5 and fixed with fasteners 14, and both gauge foils 15 and 15 are installed at the lower part of the support rods 13. The foil 15.15 is installed and configured to be vertically adjustable.

However, in an orchard of grapes, apples, etc., the vehicle A
When the rotors 2, 2 are moved forward in the direction of the arrow A by the driving force of the arrow A, trench digging can be performed without rotating the rotaries 2, 2 in the direction of the arrow. The flow flows from both sides 5a, 5a along the lifting guide covers 4, 4 as shown by the arrows, and when digging a deep trench, as shown in FIG. It is possible to dig a wide trench by moving in and lifting soil upwards.

Note that by adjusting the gauge wheel 15, the trench can be gradually deepened to form a deep trench, and the trench is backfilled with compost or straw.

FIG. 4 is a perspective view of the main parts.

As described above, in the present invention, the rotary case 1 is connected to the traveling vehicle A, and the up-cut rotary rotaries 2, 2 are installed on both sides of the lower part of the rotary case 1 so as to be able to dig grooves.
A narrow rotary cover 3 in the front and rear direction is attached to the upper part of the rotary case 1, and on both sides of the rotary cover 3, soil lifting guide covers 4, 4, which are inclined toward the upper side of the rotary case 1, are installed. On the lower surface of the rotary cover 3, which supports the support rod 13 of the gauge wheel 15 at the front of the mud scattering side, there is a rectifying plate 5 whose both side surfaces 5a, 5a are inclined upward.
is installed so that the extension directions of both side surfaces 5a, 5a are connected to the slopes of the soil lifting guide covers 4, 4, and both side surfaces 5a, 5a are
, 5a are provided at the terminal ends of the mud lifting guide covers 4, 4, which are pivotally connected by the hinges 12, 12, and are rotated about the hinges 12, 12 for adjustment. Since the direction of the jump can be adjusted in incline, the following effects can be achieved.

First, the mud that is excavated and thrown up by the up-cut rotary rotaries 2 and 2 creates obstacles on the lower surface of the rotary cover 3 at the front of the aircraft, which is the path for the scattered soil, especially on the gauge wheels and their support rods. However, as in the present invention, the gauge wheel 15
By providing a current plate to surround the support rod 13, the flow of mud in this area can be made smooth.

Second, in addition to providing a current plate, a lifting guide cover is extended from the upper end of the current plate, and this can be rotated with a hinge, so that after the flow is rectified by the current plate, the soil lifting guide cover is moved in the direction of the lifting direction. It is now possible to control the direction of the flow of earth and sand, which is oriented in a fixed direction, in response to changes in groove depth, ridge shape, and crop growth rate. It was something that I was able to leave alone.
