Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile agricultural machine guiding cable for burying a cable for guiding a mobile agricultural machine, such as a speed sprayer, which operates automatically in a field or an orchard while operating in the ground. Regarding buried machines.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Publication No. 2-31405, a mobile agricultural machine such as a speed sprayer is automatically guided along a cable buried in the ground such as a field or an orchard. It is known to work while running.

[0003]

However, an burying machine for burying the cable in the ground is not well known, and in practice, the cable is buried by digging a groove with a trench digging machine. There was a problem that it was poor in performance and was buried with the depth not stable.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised so as to solve such a problem and efficiently bury a cable effectively. Therefore, at least a vehicle body which is driven by both left and right wheels can be used. A rotary 2 is provided at the rear part, and a resistance rod 4 is vertically provided at the rear of the rotary 2 so that a lower part thereof is bent backward and the lower end of the resistance bar 4 can be extended while extending a guide cable for a mobile agricultural machine. The rear of the resistance rod is equipped with a leveling plate or a pressure roller, and a guide tube for guiding a cable is fixedly installed on the back of the resistance rod and a blade edge is provided on the front edge of the resistance rod. The rotary rod is not pivoted over its entire length, or the resistance rod is pivotally attached to the front of the upper part of the rotary bar so as to be rotatable, and the ground leveling plate is provided with an embankment forming part capable of embankment above the embedded cable. Multiple extending to One in which was constructed as consisting of straight nails.

[0005]

Therefore, at least the wheels are plunged by the rotary while the body is moving forward, but when the rotary is composed of straight claws, it is possible to deep plowing without keeping the soil out, and then the resistance is applied. The bent lower part of the rod penetrates deeply into the ground, and a resistance rod having a blade edge at the leading edge can particularly stably penetrate deep into the ground to dive, and the cable can be grounded from the lower end of the resistance rod. It will be able to effectively feed deep inside, after that it will be possible to cover the soil with the ground leveling plate or the crushing roller to effectively level the ground, and in the state where the aircraft is performing burial work while turning, The resistance rod rotates around the vertical axis, and the cable can be stably embedded in the soil while following the turning direction without difficulty.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of the entire burying machine, in which both wheels 1
A rotary working machine B is connected to the rear of a management machine A having a, 1b, an engine 9, a handle 10 and the like, and a claw shaft 12 extending to both sides of the lower part of the tillage case 11 of the rotary working machine B is provided. Is equipped with a rotary 2 composed of a plurality of straight claws 2a extending without bending over the entire length, and the lower part of a resistance rod 4 vertically extending to the rear of the rotary working machine B is bent backward and its front edge extending to the lower end is A blade edge 4a is formed on the back side of the resistance rod 4, and a guide tube 7 for guiding a cable extending to the lower end of the resistance rod 4 is fixedly installed on the back surface of the resistance rod 4. It is fitted and fixed by a set bolt 14, and is pivotally attached to a hitch 16 mounted on the rear part of the rotary frame 15 of the rotary working machine B so that the front part of the support bracket 13 can rotate about the vertical axis 8. In addition, both adjusting bolts 17, 17 capable of restricting the rotation range thereof are mounted on both sides of the vertical axis 8, and the resistance rod 4 itself has a pipe structure so that a cable can be guided. You can also

At the rear portion of the support frame 18 extending rearward from the upper end portion of the resistance rod 4, a guide wire 3 for a mobile agricultural machine is wound into a twisted wire so that it can be easily fed out and is resistant to bending and stepping pressure. The mounted reel 19 is mounted on the shaft, and the guide tube 7
A guide roller 20a, 20b for guiding a cable is axially mounted on a support frame 18 between the upper end of the upper part and the reel 19, and a support metal 21 is mounted on the upper part of the resistance rod 4 so as to be vertically adjustable. A stay 22 extending further is provided with a leveling plate 5 that can level the ground evenly in the vicinity of the resistance rod 4, and at the center rear part of the leveling plate 5 above the cable 3 buried in the ground. The embankment forming portion 5a capable of embankment is formed in the shape of a mountain, but instead of the leveling plate 5, a pressure suppressing roller 6 is provided, or a pressure suppressing roller 6 is provided behind the leveling plate 5. It can also be configured.

Therefore, when the vehicle body is advanced in the direction of arrow A by both wheels 1a and 1b, it is plunged by the rotary 2 which rotates as shown by arrow B, but when the rotary 2 is composed of the straight claws 2a, It becomes possible to cultivate the soil without exposing the soil, and then the bent lower part of the resistance rod 4 is deeply inserted into the ground to form the resistance rod 4 having the blade edge 4a.
In particular, it becomes possible to dive deep into the ground in a stable manner, and the guide roller 20a, 20
As shown in FIG. 8, the cable 3 can be embedded in the deep groove formed by the blade edge 4a in a state in which the cable 3 guided into the guide tube 7 via b is led out rearward from the lower end portion of the resistance rod 4. After that, it is possible to cover the soil with the embankment forming portion 5a of the ground leveling plate 5 or to level the ground with the crushing roller 6. Further, in a state where the aircraft is performing the burial work while turning, the resistance rod 4 is The cable 3 can be stably embedded in the soil while rotating around the vertical axis 8 and smoothly following the turning direction.

Other examples are shown in FIGS. 9 and 10, each of which is a gauge for laying a cable, and as shown in FIG. 11, the guiding cable 3 of the mobile agricultural machine C is used in the orchard by the burying machine. When embedding, it is difficult to embed the cable 3 in a place where the mobile agricultural machine C turns, but as shown in FIG.
When the gauge blocks 23 are assembled and laid on the ground as shown in 0, the cable 3 can be effectively laid by the burying machine according to the gauge.

[0010]

As described above, according to the present invention, both wheels 1a, 1b are provided.
By plowing with the rotary 2 while advancing the airframe by the method, particularly in the case of the straight claw 2a, it is possible to effectively dig deep without keeping the soil out, and then the bent lower part of the resistance rod 4 is deeply buried in the ground. Put in the blade edge 4a on the front edge.
With the resistance rod 4 having, it becomes possible to stably dive deep into the ground and dive, and the cable 3 can be effectively extended deep into the ground from the lower end of the resistance rod 4, and thereafter. Leveling plate 5 or pressure roller 6
Will cover the soil and effectively ground the ground,
Further, in a state in which the aircraft performs the burying work while turning, the resistance rod 4 rotates about the vertical axis 8 and the cable 3 can be stably buried in the soil while reasonably following the turning direction. It has a feature that it can be suitably implemented as an burying machine that can bury the cable 3 deeply and stably in the ground.
