Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a radish digging device used as an attachment for a tractor.

(B) Conventional Technology Conventionally, the technology relating to the vibration type digging device for green onions and tree seedlings has been publicly known.

However, since the green onions are grown in high ridges, they can be easily pulled out by digging the hem of the high ridges.

In addition, since tree seedlings are also grown in strips of a certain width, it is possible to easily dig each soil with a U-shaped digging blade that passes through the bottom of this strip. is there.

(C) Issues to be solved by the invention However, in the case of radish, it is often flat ridge rather than high ridge, and it is planted in rows at regular intervals, but since the underground part is deep, The U-shaped digging blade requires a large amount of power and cannot be dug.

You can also vibrate the L-shaped digging blade to bite it from the side of the ridge of the radish to cut the soil under the radish, but do not cut the radish to the depth of the radish. like,
In addition, it is difficult to maintain the depth to the extent that it does not cut into the plow.

In order to eliminate such a defect of the conventional technique, in addition to the vibration beam for mounting the radish digging blade 1, a tail wheel mounting beam that does not vibrate is provided, and by the support tail wheel attached to the tail wheel mounting beam, The bite depth of the radish digging blade was determined, and the weight of the entire radish digging device was supported by the supporting tail wheel.

As a result, since the vibrating beam does not have a supporting force, it is sufficient to vibrate the radish digging blade 1, and the vibration is surely performed, and the vibrating beam 3 and the radish digging blade 1 do not have a supporting force. The radish digging blade 1 is constructed so that it can be dedicated to digging.

(D) Means for Solving the Problems The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

Attach the digging frame 17 to the work equipment mounting device of the tractor,
A tail wheel mounting beam 9 is projected in the left and right direction of the digging frame 17, and a vibration beam 3 which is capable of forward and backward vibration by a crank shaft 15 supported by the digging frame 17 is projected in the left and right direction,
The supporting tail wheels 7 and 8 are fixed to the left and right ends of the tail wheel mounting beam 9, and the L-shaped radish digging blade 1 is fixed to the vibration beams 3 at the other left and right ends. It is located outside the left and right wheels.

(E) Embodiment The problems to be solved and the means for solving the present invention are as described above. Next, the structure of the embodiment shown in the accompanying drawings will be described.

In FIG. 1, a digging frame 17 is supported by a three-point link type working machine mounting device provided at the rear of the tractor T.
From the digging frame 17, a stand 14 that supports the entire radish digging device when not in use is provided so as to be vertically fixed.

A crankshaft 15 is bearing-supported between the left and right excavation frames 17, and the crankshaft 15 supports the PTO shaft 2 of the tractor T.
Power is transmitted from 3 through the universal joint.

Further, the tail wheel mounting beam 9 is fixed to the digging frame 17 so as to project in the left and right directions, and the supporting tail wheels 7 and 8 are mounted on either the left or right side of the tail wheel mounting beam 9. The supporting tail wheels 7 and 8 may be one wheel as long as they are wide tail wheels.

Further, the vibrating arm 6 is pivotally supported between the excavating frame 17 via the vibrating pivot shaft 16, a vibrating bracket 21 is provided at the rear portion of the vibrating arm 6, and the beam bracket 18 is attached to and detached from the vibrating bracket 21. It is possible.

In order to easily attach the beam bracket 18 to the vibration bracket 21, an engaging recess is provided in the upper part of the vibration bracket 21, and the locking pin 5 provided in the upper part of the beam bracket 18.
It is possible to temporarily fix it by hooking 5. Reference numeral 4 is a support plate for the beam bracket 18.

The blade mounting bracket 10 is mounted on the left and right ends of the vibration beam 3 fixed to the vibration bracket 21 at the beam bracket 18, and the radish digging blade 1 is fixed to the blade mounting bracket 10.

As shown in FIGS. 2 and 3, when the support tail wheels 7.8 are mounted on the tail wheel mounting beam 9 on the left side of the tail wheel mounting beam 9, the radish digging blade 1 is mounted on the right side of the vibration beam 3. The radish digging blade 1 is mounted so that the digging portion 1a is located outside the wheels 22 of the tractor T.

In FIG. 3, the radish digging blade 1 is mounted on the right side, and the support tail wheels 7.8 are mounted on the left side.

Then, the tractor T travels in the already excavated portion of the radish field and always goes in one direction outside the remaining strip to continue excavation.

FIG. 4 is a drawing of the vibration drive portion of the crankshaft 15 and the vibration arm 6. The rotation from the PTO shaft 23 is transmitted to the crankshaft 15 via a universal joint, and the crankshaft 15 is rotated.
The rear end portion of the ball joint is configured as a crank portion, and the ball joint 20 is pivotally connected to the portion.
The other end of 20 is pivotally connected to the front end of the vibrating arm 6.

With this structure, when the crankshaft 15 is rotated, the vibrating arm 6 is vertically moved about the vibrating pivot shaft 16 via the ball joint 20.

FIGS. 5 and 6 show the vibrating beam 3 and the beam bracket 18. In this embodiment, locking pins 5, 5 are provided only on the upper part of the beam bracket 18, and mounting bolt holes are also provided. Since the top and bottom are asymmetric, the left and right of the vibration beam 3 cannot be replaced.

In the embodiment shown in FIGS. 7 and 8, the beam bracket is used.
Since the locking pins 5 and 5 are provided on the upper part of 18 and the mounting bolt holes are also vertically symmetrical, they can be mounted even if the left and right are swapped, and the radish excavating blade is located at a position apart from the center of the tractor T on both sides. It is now possible to wear 1.

9 and 10 show a structure in which the blade mounting bracket 10 is mounted on the vibration beam 3, and the blade mounting bracket 10 can change and adjust the mounting position on the left and right of the vibration beam 3.

Further, the blade mounting plate 2 is projected rearward from the blade mounting bracket 10, and the upper end of the radish digging blade 1 is bolted to the blade mounting plate 2.

FIG. 11, FIG. 12, and FIG. 13 show the structure of the radish digging blade 1, and the L-shaped lower horizontal portion constitutes the digging portion 1a.

FIGS. 14 and 15 show a configuration in which the supporting tail wheels 7.8 and the tail wheel supporting rods 12 and 13 are mounted on the tail wheel mounting beam 9.

(F) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

First, since the supporting tail wheels 7 and 8 are provided on one of the left and right to support and ground the weight of the radish digging device, and the radish digging blade 1 is provided on the other to cut the soil, the left and right resistance is reduced. These offset each other, and the receding of the tractor T is less likely to be hindered by the excavation resistance of the radish digging blade 1.

Secondly, since the supporting tail wheels 7 and 8 support the own weight of the radish digging device, there is no need to support the own weight of the radish digging blade 1, and vibration in the front-rear direction can be freely made with less resistance. The excavation resistance is also reduced.

Thirdly, since the height of the radish digging device is constantly supported by the support tail wheels 7 and 8, the lower end of the radish digging blade 1 is lifted to cut the radish D or cut into the cultivator near the tractor, The problem of not being able to run T has decreased.
