Description

DETAILED DESCRIPTION OF THE INVENTION Field of Application of IT Industry 4- This invention relates to a tilling shaft theory 6 device for a rotary tilling section, and is used when removing γj from the tilling shaft.

Problems to be Solved by the Prior Art and the Invention For example, when replacing a tilling shaft with another tilling shaft depending on the type of rotary tilling work, the tilling shaft is usually long and has many tilling blades installed. Because of this, the V is not easy to replace, and the shape makes it difficult to hold due to hair, and it is therefore dangerous.

In order to solve the problem [, 1 sentence] This invention has a tiller blade (B installed): 1 LF provided on the 1-side rear force of the tiller blade (B) and +iii rear movement and lateral movement l. ■ A suspension rod (4) for suspending the tilling shaft (2) when the tilling shaft (2) is removed from the γ1 is provided on the mounting body (3) that is equipped with a functional accessory working machine so that it can be removed freely. The structure of the tilling shaft attachment/detachment device for the rotary tilling section is as follows.

Functions and Effects of the Invention After attaching the suspension rod (4) to the mounting γi part (3) to suspend the tilling shaft (2) and removing the support member supporting the tilling shaft (2), &Jt Depending on the support configuration of the plowing shaft (2), for example, the attached body (3) is moved in the J direction of the plowing side, then moved to the rear JJ, and then moved to the F force in the opposite direction, and the tilling blade (1) (1)
When the tiller shaft (2) is removed by touching the ground, V!
:Okay, and conversely, when installing the tilling shaft (2), you can use the same order as when removing it.

In this way, the long and bulky plowing shaft (2) can be attached and detached without the need to suspend it with a ``branch'', which makes the operation easy and does not involve any risk.

In the illustrated example, a transmission case (6) is provided in which a power shaft (5) for transmitting power to the tractor's power take-off shaft projects forward and has a transmission mechanism inside.
The link mast (7) connected to the upper link on the tractor side is provided on the t side, and the connecting member (8) connected to the nullor link is provided on both left and right sides, and the left side of this transmission case (6) is provided with a link mast (7) connected to the upper link on the tractor side. , a pipe-shaped shaft case (9) with a left-right transmission shaft inside is combined, and the left end of this shaft case (9) has a shaft bearing part (10) at the lower end and a transmission mechanism is installed inside. The side case (11) is suspended. Also, on the right side of this transmission case (6), there is a hexagonal hole (12) in the left-right direction at the right end and a female threaded part (12) on the left side of this hexagonal hole (12).
13) and a pipe-shaped connecting body (14) having
The hexagonal hole (12) is located at the right end of the connecting body (14).
Hexagonal shaft part (15) that fits into the F end shaft bearing part (16)
The shaft bearing body (17) having the
One part of 7) is a bolt (L, S) that passes through the hexagonal shaft part (15) and screws into the four internal thread parts (13) l;
-Therefore, we conclude.

The shaft bearing part (lO) of the id case (eye) to be described is a hexagonal shaft (lO) with a female screw part at the end and a hexagonal outer periphery.
9) protrudes toward the right, and a hexagonal shaft (20) having a through hole and a hexagonal outer periphery is provided in the shaft bearing part (16) of the shaft bearing body (17), facing leftward. This shaft bearing part (
A tilling blade (1) is installed on the outer periphery between the IB) and the shaft bearing part (10) of the side case (11), and is fitted to the hexagonal shafts (19) and (20) at both left and right ends, respectively. A pipe-shaped tilling shaft (?) with a hexagonal hole is provided, and this tilling shaft (two
) is fastened by a long pole (21) that passes through the through hole of the hexagonal shaft (20) and is screwed into the female threaded portion of the hexagonal shaft (19).

Further, a plate-shaped mounting member (22) adjacent to the shaft bearing (17) is coupled to the r side of the right end of the connecting body (14),
A rotary cover (23) is provided between the attachment member (22) and the side case (11) to cover the two sides of the planting and cultivating blades (1), (i), . . . .

Left and right pin support members (24) (24) are provided on the outer periphery of the connecting body (14) and the outer periphery of the shaft case (9), respectively, protruding rearward. 2
4) In (24), pipe-shaped guide bodies (2B) (2B) each having a sliding hole (25) in the front and back direction are supported by a bottle, and these guide bodies (26) (26)
The upper part of the rear end is connected by a connecting member (28) having a bottle support part (27) projecting upward in the center part in the left and right direction, and the upper part of the transmission case (6) has an upper end. An arm rod (29) having a bottle support part is protrudingly installed 2, and a telescoping rod (30) that is supported on the bottle support part (27) and expands and contracts by a screw mechanism is supported on this bottle support part. let

The sliding holes (2) of the left and right guide bodies (2B) (2B)
5) In (25), a pair of left and right sliding rods (32) (3
2) is slidably inserted, and this sliding guide part (31
) and the transmission case (6).
) is provided with a double-acting hydraulic cylinder (30) that operates both in expansion and contraction, and both front and rear ends are pivotally connected.

This sliding guide 1 (31
) and a plate-like body part with a square j defect (36) at one end of -F (3).
1 so that it can slide left and right, and on the rear side of this mounting body (3), there is a notch (36) at the ↑ end 1 - downward bearing part (37) and - 1 two ends. A plate-shaped body (39) having a connecting hook part (38) is suspended, and this shaft bearing part (37)
In this case, a support (40) whose lower end is located near the tilling shaft (2) is rotatably supported with vertical movement. is the tilling axis (2)
-Nino-- When the two tilling blades (1) are held in place, a hook-shaped support member (41) that can support the tilling shaft (2) from the F side
), and these supports (40) and plate-shaped bodies (39) constitute a suspension rod (4).

Note that (42) is a handle that expands and contracts the telescoping rod (30) by rotation.

Next, the effect will be explained. The input of the input shaft (5) is transmitted through the transmission mechanism in the transmission case (6), the transmission shaft in the shaft case (9), the transmission mechanism in the side case (11), and the hexagonal shaft (19). Shaft (2) and tilling blade (1) (1
)... is transmitted.

When the handle (42) is rotated in one direction or the opposite direction, the left and right guide bodies (2E
l) (2B), the sliding rod (32) (32) and the attached body (3) rotate upward or downward, and when the hydraulic cylinder (34) is operated to the extension side or the contraction side, the 5 left and right slides The moving rod (32) (32) and the mounting body (3) slide rearward or forward.

When removing the tilling shaft (2), first support the tilling shaft (2) from below by holding one tilling blade (1) on the support member (41) of the hanging rod (4). Along with the attached body (
3) by adjusting the hook part (38) up and down to the notch part (36)
Then, after removing the bolts (18) and (21) under -L and removing the bearing body (17), move the suspension rod (4) to the right by the sliding guide part (31). If you let
The left end of the tilling shaft (2) is removed from the hexagonal shaft (19), and the tilling shaft (2) suspended by the suspension rod (4) can be moved rearward by the hydraulic cylinder (34). , can be rotated as appropriate by the shaft bearing (37), and lowered to a selected position by operating the handle (42) to bring the tilling blade (1) (1)-φ. Conversely, when installing the tilling shaft (2), the above-mentioned removal order may be reversed.
