Description

[Detailed Description of the Invention] This invention relates to a vibrating subsoiler, and aims to provide a vibrating subsoiler that has good left-right balance, facilitates width side joints, and forms an underdrain efficiently.

For this purpose, the following technical measures were taken in this invention.

That is, a transmission case having an input shaft driven by obtaining rotational power from the towing vehicle body and an output shaft mounted in a direction orthogonal to the input shaft is fixed to the center of the machine frame.
A frame is positioned on the outside of the transmission case to support the vertical blade which swings back and forth by receiving rotational power from the output shaft, and this frame moves laterally with respect to the machine frame. Vibrating type 2 characterized by being configured to be adjustable
The structure will be a series of subsoilers.

An embodiment of this invention will be described below based on the drawings.

First, to explain the structure, A shows the left half of a vibrating twin subsoiler that is mounted in the rear of an agricultural tractor (drawings omitted) so that it can be raised and lowered, and 1 shows the machine frame installed laterally. , 2 is an arm protruding forward from the front end of this machine frame 1, 3 is a pin connecting the lower link (not shown) on the agricultural 1-rafter (not shown) side, 4 is an input shaft, and 5 is a transmission case. 6, the crankshaft is rotatably extended to the right and left by an appropriate length and is mounted on an axis, and has a pin hole 7a at its outer end into which a pin can be inserted.

Reference numeral 8 denotes a support frame having opposing plates Ba, Ba, and at the rear of this support frame 8 is a blade mounting plate to which a vertical blade 9 having a blade on its front edge and traveling through the soil is integrally fixed. 10,
It is pivotally mounted around a bolt 11 so as to be swingable back and forth,
Further, in the front part of the support frame 8, there is provided a notch 12 having a U-shaped side surface into which the lower part of the machine frame 1 is fitted, and opposing plates 8 at the front and rear of the notch 12. A plate 13.13 having a female threaded portion (not shown) is welded between a and 8b.

14 is a support frame 8 for a vibrating subsoiler on the machine frame 1.
This is a tightening plate for attaching the plate, and the bolt 15°15 shall be tightened so as to correspond to the female threaded part (not shown) of plate 13.13.

Reference numeral 16 denotes a crankshaft which is supported by bearings on the inner facing plate 8a, and this crankshaft 16 extends to a suitable length in the lateral direction, and has a pin hole 7b at its inner end. A rotating disk 17 is integrally fixed to the crankshaft 16 at its outer end.

18 is connected to the blade mounting plate 10 via a link ball 19.
The other end of the crank 18 is loosely fitted and supported by a pin 20 fixed outwardly at the radially outer end of the rotating disk 17.

Reference numeral 21 denotes a cylindrical joint that connects the above-mentioned crankshafts 5 and 16, and mounting holes 21a are bored at appropriate intervals in the longitudinal direction of the joint 21. When connecting both crankshafts 5.16, the pin holes 7a, 7b of both crankshafts 5, 16 are made to correspond to the mounting holes 21a, 21a at appropriate positions of the joint 21, and pins (not shown) are connected. The structure is such that they are inserted and connected.

In the figure, 22 is a mast that connects the top link (not shown) of an agricultural tractor (not shown), and 23 is a vertical blade 9.
The blade 24 is a bullet connected to the lower part of the vertical blade 9 to form a culvert.

Next, the effect will be explained.

Power take-off shaft of agricultural tractor (drawing omitted)
When the rotational power of the engine (not shown in the drawings) is transmitted to the input shaft 4 side by connecting the input shaft 4 and the input shaft 4 through a universal joint or the like, the two crankshafts L-5 and 16 connected by another joint 21 are connected. begin to rotate as one.

When the rotating disk 17 fixed to the outer end of the crankshaft 16 rotates, the crank 18 whose tip is loosely fitted and supported by the pin 20 starts reciprocating motion in the direction of the arrow shown in FIG. swings back and forth around the bolt 11, expanding and softening the soil.

When adjusting the underdrain formation, the pin (
(Figures omitted), then loosen the bolts 15°15, slide the support frame 8 fixed to the machine frame 1 laterally, and connect the rank shuffles 1-5 and 16 again at the appropriate position. 15.1 from Pol on support frame 8)
Tighten 5.

Since this invention is configured as described above, it has the following technical effects.

That is, the vertical blade body 9 forms a vertical groove while excavating the soil.
, 9 are supported by the frames 8, 8, and the frames 8, 8 can be moved and adjusted in the left and right directions along the machine frame 1, so that a single vibrating subsoiler can be easily and quickly installed during underdrain construction. It can be moved.

The two vibrating sub-soilers are provided on both left and right sides of the transmission case 6, and vibrate the vertical blade bodies 9, 9 using the rotational power of the output shafts 5, 5 distributed from the transmission case 6 to the left and right. Because of this, the power transmission is smooth, the overall structure of the device can be simplified, and the left and right balance during operation is also good.
