Description

[Detailed description of the invention] Industrial applications The present invention relates to a tractor plowing device.

Prior Art and Problems to be Solved by the Invention When the left and right drive shafts are driven by a transmission mechanism built into a central transmission case, the left and right shaft ends are rearward of the center with respect to the direction in which they are towed. In a tillage work device in which disks are bent as much as possible and disposed on the bending drive shaft to till the soil by rotating while being towed, the left and right discs are arranged opposite to each other. The soil plowed by the discs moved toward the center, and the raised soil in the center comes into contact with the transmission case in the center, creating traction resistance, and the transmission case. It is difficult to stabilize the plowing depth because the soil is pushed up.

This invention aims to reduce traction resistance by eliminating the soil that bulges up in the center, and to stabilize the plowing depth.

Means for Solving the Problems This invention provides a disc (1) that plows soil by rotating while being towed. The structure of the tractor plowing device is preferably arranged on the drive shaft (3) in an oblique direction.

Functions and Effects of the Invention The left and right discs (1), which are rotated by the drive shaft (3) while being towed by a tractor, plow the soil and move the plowed soil toward the outside in the slope direction. Therefore, the plowed soil in the center is also distributed left and right to form a groove, and the transmission case (2) in the center moves along this groove-like position, so there is no traction resistance due to contact with the raised soil. , and can maintain a constant plowing depth.

Embodiment In the illustrated example, an upper link (4) is provided at the upper end,
A mounting mast (6) is provided at the lower end to which a pair of left and right lower links 451f5) are pivoted, and above the pivoting portions of the pair of lower links f515) of the mounting mast +61, there are left and right mounting masts that project rearward. A pair of frames (71) are fixed to each other, and a transmission mechanism is installed inside the rear end of the pair of frames (71), which has an input shaft (8) that protrudes forward at the top. The transmission case (2) is connected by the left and right support members (1) (10), and the transmission case (2) is
) and the upper part of the mounting mast (6) are connected by a pair of left and right plate-shaped reinforcing members (IINI+).

From the rear ends of the left and right frames (7) (71), there are a pair of left and right pipe-shaped support rods (1
δflip protrudes, and the left and right support rods (the side ends of 121 and the left and right frames f7) (the front ends of 71 are connected to a pair of left and right reinforcing members (131 (+31), respectively, and the left and right support rods are The tip of the rod (Ia (121) is
A shaft bearing part (a plate-shaped shaft bearing body with 1 shaft (I!IO
hang down each.

At the lower end of the transmission case (2), there is provided a pair of left and right refraction transmission bodies (formerly referred to as "former") that can be transmitted to the transmission mechanism and refracted by a universal joint or a bevel gear, etc.
The power is transmitted to this refraction transmission body (1e) and the shaft bearing part (
A pair of left and right drive shafts supported by +31 +31
, and on these left and right drive shafts (31, shallow bowl-shaped disks (1) are appropriately arranged so as to face each other left and right with their backs facing inwards. Note that (lη is the transmission case) (2) a gauge wheel installed on the rear side that can adjust the plowing depth;
I is the input shaft (
8) is a connecting shaft that transmits power.

Next, the effect will be explained. The power of the tractor's power take-off shaft is transmitted to the left and right refractive power transmission units fun (IGI) via the connection shaft (IF3, input shaft (8), and transmission mechanism), and then to the left and right drive units (3) (3) The left and right disks (1) (1) are rotated through the.

When the tractor moves forward, the left and right rotating discs (
11 (11 digs into the soil and plows it, and each disc (1) on the left side from the center part by slope moves the plowed soil to the left, and each disc on the right side [ )(1
) respectively move the tilled soil to the right. At this time, the left and right discs (11) in the central part move the tilled soil from the central part to the left and right by their respective inclinations, so the plowed soil in the central part becomes a groove shape.

[Brief explanation of drawings]

The figures show one embodiment of the invention, with FIG. 1 being a plan view and FIG. 2 being a side view. In the figure, code (1) is a disk, (2) is a transmission case, and (3)
indicates the drive shaft.

Claims (1)

[Claims] A disc (1) that plows the soil by rotating while being towed is moved from a transmission case (2) in the center to a drive shaft (3) whose left and right shaft ends are oriented as diagonally as possible toward the traction direction.
