SOLUTION: This ridging machine is equipped with an upper roller 2 and side rollers 3 which are driven to roll on the upper face and the side faces of the culture soil as pressing them on the rear side of the culture soil plate 1 for forming the culture soil to a ridge of a prescribed width.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge forming machine for forming ridges for cultivating crops, which can be mounted on a tractor to perform work.

[0002]

In the ridge forming for transplanting crop seedlings, the condition that the surface of the ridges is tight to a certain degree improves the adhesion or vigor of the roots of the seedlings to the soil, and the holding posture of the seedlings planted. Easy to maintain.

[0003]

According to the present invention, there is provided an upper surface on which a ridge upper surface A to be cultivated and a ridge side surface B on both right and left sides are rotated and pressure-reduced, on the rear side of a cultivation plate 1 for cultivating a ridge with a predetermined ridge width. A ridge forming machine including the roller 2 and the side roller 3 is provided.

[0004]

According to the present invention, a ridge forming machine is mounted on the rear side of a rotary tilling device or the like of a tractor to perform a soil ridge forming operation. An upper roller 2 is provided on the upper surface of the ridge having a fixed width cultivated by the cultivation plate 1.
Is crushed while being driven to rotate, and the side surface roller 3 is crushed while being driven to rotate on the ridge side surface B cultivated by the cultivation plate 1.

For this reason, the ridge cultivated by the cultivation plate 1 collapses because the upper surface roller 2 and the side surface roller 3 are forcibly compressed by the three upper surfaces A and the right and left ridge side surfaces B, which are rotationally driven. Difficult, and the ridge upper surface A can be appropriately compacted to facilitate adaptation to planting of crop seedlings. Also, the ridged soil whose ridge upper surface A is crushed by the upper surface roller 2 has a side surface pressed by the cultivation plate 1 and the side surface roller 3, so that the tightening and fixing of the ridged soil surface is also stabilized, and accurate ridge forming is performed. be able to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A rotary tilling device 5 is provided on the rear side of a tractor body 4.
At the same time, the ridge forming machine 6 is mounted. The vehicle body 4 is in a front-rear four-wheel drive mode, and a lift rod 8
And a top link 10 that is turned up and down through the tilling device 5 so that the tillage device 5 can be connected to and lifted off. Reference numeral 11 denotes a PTO shaft, which works with the tillage device 5. 12 is a rear wheel, 13 is a fender, and 14 is a rear axle housing.

The tillage device 5 has a tillage case 15 at the center in the lateral width direction, and a center drive configuration in which a tillage shaft 17 is arranged by projecting a tillage shaft 16 on both left and right sides below the tillage case 15. And The transmission case 18 is made to protrude rearward from one upper side of the tilling case 15, and the upper surface roller 2 and the side surface roller 3 are driven to rotate. A mast 19 is provided between the mast and the transmission case 18 with a telescopic rod 20 which can be telescopically operated by operating a handle.
The vertical adjustment of the ridge forming machine 6 with respect to the tillage device 5 can be performed. 21 is a tillage cover.

The ridge forming machine 6 comprises a breeding plate 1, an upper roller 2 for suppressing a ridge upper surface A of a ridge C cultivated by the cultivating plate 1, and a side roller 3 for reducing a ridge side surface B. You. The cultivation plate 1 can be formed by cultivating the left and right sides of the soil cultivated by the tilling device 5 to form a cultivation groove D, and forming the left and right sides of the ridge C as ridge side surfaces B of an inclined surface.
In the example shown in the figure, the cultivation plate 1 is formed symmetrically in an inverted figure on both the left and right sides, but it may be a single cultivation form formed only on the side of the forming ridge C on the center side.

The upper surface roller 2 is for horizontally compressing the upper surface A of the cultivation ridge formed between the left and right cultivation plates 1, is provided above the rear side of the cultivation plate 1, and is provided with the transmission case 18.
A shaft 23 is mounted on the rear end of the transmission case 22 which is supported to be vertically swingable with respect to the rear end of the transmission case 18.
It is driven and rotated through a chain mechanism and the like in the motor 22. The upper roller 2 is in the form of a flat roll, but may be replaced by an upper roller 2A in the form of a corrugated roll or a spiral roll in which corrugations are formed on the peripheral surface. In the spiral roll form, the soil on the ridge upper surface A is scraped and leveled to the center to level. Reference numeral 27 denotes an arm protruding from the transmission case 18.
And crushed downwards to suppress them.

The side surface roller 3 is provided behind the portion where the left and right cultivation plates 1 suppress the ridge side surface B, and has a conical roll form, but may have a simple flat roll form. The roller shaft 24 has an eight-letter shape with the lower end side expanding outward, and is inclined backward and downward. The pressure-reducing surface formed by the rotation of the side surface roller 3 is arranged so as to be parallel to the ridge side surface B which is the cultivation surface of the cultivation plate 1.

The transmission of these side rollers 3 is performed by connecting a transmission shaft 26 interlocked via a universal joint from a transmission shaft 25 at the rear end of the transmission case 18 to a front roller shaft 24. The height of the ridge forming machine 6 is adjusted by the telescopic rod 20, and the lift arm 7 is moved down to set the tilling apparatus 5 and the ridge forming machine 6 in the working position. As the vehicle body 4 advances, the tilling claw 17 is rotated in the tilling device 5 to till the soil surface,
Or crush the soil. The cultivated soil surface is a cultivation plate 1
The soil is cultivated, and a cultivation groove D is formed in the trace where the cultivation plate 1 passes. At the same time, the ridge side surface B formed by the cultivation plate 1 is crushed by the driving rotation of the side surface roller 3.

Such upper roller 2 and side roller 3
The transmission cases 18 and 2 are rotated together with the rotation of the tilling shaft 16.
Since it is driven and rotated through the power transmission mechanism 25, the power transmission shafts 25 and 26, etc., smooth and effective pressure suppression is performed, and the soil surface can be compacted appropriately. In order to suppress the pressure, the pressing force of the spring 28 of the upper roller 2 may be adjusted, or a spring for pressing the side roller 3 may be provided.
