Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention enables the second tilling shaft of a two-shaft rotary to be rotated over a large angle range, thereby further enhancing tilling performance and increasing versatility. This is related to the shaft deep plowing rotary.

2. Description of the Related Art Conventionally, as shown in FIG. 4, a two-shaft rotary is known in which a first tilling shaft 6 and a second tilling shaft 13 are directly driven by a side drive system using an upper horizontal transmission shaft 2. ing.

In this type of two-shaft rotary, the upper horizontal transmission shaft 2 and the second tilling shaft 13 are connected by a power transmission mechanism 26 with a narrow expansion/contraction range, and this power transmission mechanism 26 also connects the upper horizontal transmission shaft 2 with the second tilling shaft 13. Since the rotation center is the rotation center, the rotation range of the second tilling shaft 13 around the first tilling shaft 6 is naturally limited, and as a result, b
There were problems such as not being able to take appropriate measures and not being able to demonstrate the original performance of the equipment.

Problems to be Solved by the Present Invention Therefore, the present invention aims to increase the performance and versatility of the two-shaft rotary by providing a structure in which the second tilling shaft of the two-shaft rotary can be rotated over a large angle range. The purpose of this project is to provide a two-shaft deep-plowing rotary embankment that can be used for deep cultivation.

Means for Solving the Problems The two-shaft deep tilling rotary according to the present invention has a second tilling shaft disposed behind the first tilling shaft, and the first tilling shaft is driven by a side drive method. In rotary,
A side-drive type power transmission mechanism that electrically connects the first tilling shaft and the second tilling shaft is rotatably provided around the first tilling shaft, and the second tilling shaft located at the tip of the power transmitting mechanism is connected to the second tilling shaft. The first tilling shaft can be rotated up to the vicinity directly below the first tilling shaft, and can be fixed at any position around the first tilling shaft, and the second tilling shaft can be rotated by the rotational driving force of the first tilling shaft transmitted from the power transmission mechanism. It is characterized by being driven.

In other words, in the present invention, power is transmitted to the second tilling shaft via a side drive type power transmission mechanism that connects the first tilling shaft and the second tilling shaft, and the power transmission mechanism Since the second tilling shaft is rotatable about the first tilling shaft, the second tilling shaft can be moved to an appropriate angular position with respect to the first tilling shaft and can transmit power. If the first tilling shaft and the second tilling shaft are arranged approximately vertically, deep tilling becomes possible, and the direction of rotation of the first tilling shaft and the second tilling shaft is reversed, so that the soil can be tilled from the front part between the two tilling shafts. By operating the tiller in a raking motion, it is possible to reverse the tillage between the bottom layer and the surface layer.Also, by raising the second tilling axis significantly higher than the first tilling axis, the first tilling axis can produce a considerable amount of plowing. It is possible to create a suitable surface layer of fine soil even if the soil is deeply raised.

EXAMPLES Below, please refer to the drawings for specific examples of the present invention! ! This will be explained in detail in a.

1st. FIG. 2 shows a two-axis deep plowing rotary according to the present invention,
Reference numeral 1 denotes an upper horizontal transmission cylinder into which an upper horizontal transmission shaft 2 is inserted, and an input shaft 4 interlockingly connected to the upper horizontal transmission shaft 2 by a hevel gear 3.3 is located in front of the central portion. A rotary case 5 is attached to the left end of the rotary case 5, and a hevel gear for interlockingly connecting the upper horizontal transmission shaft 2 and the first tilling shaft 6 is installed inside the rotary case 5. -7,8
A side support 10 for supporting the free end of the first tilling shaft 6 is provided on the opposite right end.

Reference numeral 11 denotes a side drive type power transmission mechanism configured to be freely rotatable around the first tilling shaft 6, which includes a case body 12 pivotally supported at the tip of the side support 10, and an inner side of the case body 12. It consists of spur gears 14 for transmitting the rotational power of the first tilling shaft 6 to the second tilling shaft 13, hevel gears 15 and 16, a connecting drive shaft 17, and the like.

A side support 18 rotatably supports the side of the second tilling shaft 13 opposite to the driving portion, and is pivotally connected to the rotary case 5 about the first tilling shaft 6 .

Further, in the second tilling shaft 13, the power transmission mechanism 1
The rotary claws 19a close to the rotary claws 19a, . Of course, a coulter (resistance element), a plow, etc. may be used instead of the cross-claw shaft system described in 11''li.

20 is a tilling cover that surrounds one of the first tilling shaft 6 and the second tilling shaft I3, and when the second tilling shaft 13 rotates, the second tilling shaft 13 is rotated.
It is fixed at a position where interference with the tilling shaft 13 can be avoided. Further, 21 is a link portion connected to a three-point link hitch mechanism of a tractor, etc., and 22 is a handle support rod pivotally supported on the upper horizontal transmission tube 1;
A position adjustment handle shaft 23 of the second tilling shaft 13 is rotatably locked to the handle shaft 23, and a cylindrical body 24 integrally supported to the case body 12 is screwed to the tip of the handle shaft 23. There is.

Reference numeral 25 denotes a support rod position adjustment handle for rotating and displacing the handle support rod 22 up and down.

The operation of this embodiment will be explained using the above configuration.

The rotational power generated by the engine of a tractor, etc. is transmitted to the input shaft 4, and the hevel gear 3... and the upper horizontal transmission shaft 2 are transmitted to the input shaft 4.
, and reaches the first tilling shaft 6 via the Heberg gear = 7.8 in the rotary case 5, the connecting drive shaft 9, etc. The rotation of the first tilling shaft 6 is transmitted to the second tilling shaft 13 through the spur gears 14 . And the rotary claw 19a mounted in a cross claw shaft manner on the second tilling shaft I3...
rotates in a suitable manner so as not to generate residual N)1 around the case body 12.

By the way, when performing deep plowing in this double rotary, the support rod position adjustment handle 25 is first adjusted to give a large rotational displacement, and then the handle fixed to the position adjustment handle shaft 23 of the second tillage shaft 13 is adjusted. The second tilling shaft 13 is positioned substantially below the first tilling shaft 6 as shown in FIG. 1, and tilling is performed by making relatively small adjustments. In this case, by directing the rotation of both plowing shafts 6.13 in the directions of arrows W and W, the rotary claws 19 act to scrape soil from the front between both plowing shafts 6.13,
Suitable tillage reversal can be performed. As shown by the two-dot chain line in Fig. 1, by positioning the second tilling shaft 13 at the uppermost position and cultivating only with the first tilling shaft 6, it is possible to achieve uniaxial tilling, and furthermore, as shown in Fig. When the second tilling shaft 13 is used in the lowered position, the fine soil performance of the second tilling shaft 13 can be suitably exhibited.

Effects of the Invention As described above, according to the present invention, the second 11th tiller can be rotationally displaced to the vicinity directly below the first tilling axis.
Deep plowing that cannot be achieved with conventional two-axis rotary is possible,
In addition, since the position of the second tilling axis can be significantly rotated around the first tilling axis, it can be used in various ways such as general tilling, fine soil, and deep tilling.
The versatility of mouth to tari is greatly increased. Therefore, the rotary is particularly useful for field crops that require various types of tillage work.
