Abstract

PURPOSE:To enable tilling to be inverted on-site free from movement of soil and to readily carry out after-treatment such as grand making, by pivoting colters to a frame at the left and right lower parts, slantingly setting a drawing up guide between the colters and laying a rotary cutting blade at the rear of the drawing up guide. CONSTITUTION:When a tilling device is earthed while traveling an agricultural tractor, colters 8... are cut into soil, beltlike soil of given width is drawn up by a drawing up guide 14 and guided upward. When the beltlike soil is cut by rotary cutting blades 18... anticlockwise revolving at the rear of the drawing up guides 14, soil is inverted and dropped. Consequently, tilling is inverted on-site, tilled soil is prevented from transferring in the traverse direction and after-treatment such as leveling or ground making is readily carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The field of application of the present invention is a tillage device connected to a power mobile agricultural machine such as an agricultural tractor or a power tiller.

[Prior art]

A plow or rotary tiller was connected to a powered mobile agricultural machine.

[Problem that the invention seeks to solve]

When plowing is performed by connecting a canopy or a plow to a powered mobile agricultural machine, the plow moves laterally, and when plowing with a rotary plowing device, there is a problem in that the reversibility of the plow deteriorates.

[Means to solve the problem]

In order to solve the above problems, the present invention takes the following technical measures. That is, coulters are pivotally connected to the frame connected to the vehicle body in a vertically movable and transmittable manner, facing each other on the left and right sides of the lower part, and a dredging guide whose tip is located below the coulter is provided diagonally between the coulters. A rotating cutting blade is provided at the rear end of the dredging guide.

[Effect]

When the vehicle runs in a rice field, the soil is cut along the traveling direction by the coulters, and the soil between the coulters is dredged up into strips by the dredging guide and moved backward and upwards, and is cut by rotation at the rear end of the dredging guide. It is cut and reversed by the blade and falls.

〔effect〕

The belt-shaped soil dredged by the dredging guide is cut and turned over by a rotating cutting blade, allowing in-situ inversion cultivation without soil movement, eliminating lateral movement of tilled soil, and facilitating post-processing such as land leveling. become.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

First, the configuration will be explained. Agricultural tiger, lid body 1
A main transmission case 6 equipped with a frame 5 and a transmission mechanism is connected to the rear of the frame 5 so as to be able to move up and down via lower links 2, 2 and a top link 3, and to transmit transmission via a universal joint 4. Coulters 8, 8, . . . are pivotally connected to supporting rods 7, 7, . At the outer ends of the left and right support tubes 9, 9 of the main transmission case 6, a side transmission case 10 is placed on the left side, and a side transmission case 10 is placed on the right side, with an interval slightly wider than the width between the coulters 8, 8 located on the left and right outer sides. A support frame 11 is provided to protrude rearward, and a lateral support rod 1 is provided between the side transmission case 10 and the side support frame 11, and a lower support frame 12 protrudes downward.
3 are being constructed.

Between the coulter 8, 8..., the tip is the coulter 8.
Dredging guides 14, 14, .
The rear side of 4.14... is fixed to the front side of the horizontal support rod 13.

And, above the rear end of the dredging guides 14, 14...
A rotary shaft 15 is disposed between the side transmission case 10 and the side support frame 11 so as to be rotatable in a counterclockwise direction, and mounting flanges 16, 16, etc. are attached to the rotary shaft 15.・The horizontal blade portions 17, 17, .
A rotary cutting blade 18°18... is installed. In addition, 19 and 19 are lower link attachment pins, and 20 is a cover.

Next, the effect will be explained. When the tiller is grounded while driving an agricultural tractor in a rice field, the coulter 8
, 8... cut into the soil, and the dredging guide 14,
14... guides the band-shaped soil of a predetermined width upward after dredging, and the band-shaped soil is removed by rotary cutting blades 18, 18... rotating counterclockwise at the rear ends of the dredging guides 14, 14... At the same time as cutting it, it is turned over and dropped.

In the above embodiment, the soil strips dredged by the dredging guides 14, 14... are cut by the rotary cutting blades 18, 18... at the rear ends of the dredging guides 14, 14... and are turned over. Since the tilled soil falls down, it becomes inverted tillage on the spot, which prevents the tilled soil from moving laterally and facilitates post-processing such as land leveling.

[Brief explanation of the drawing]

The drawings show one embodiment of the invention, with FIG. 1 being a side view of the main parts, FIG. 2 being a plan view, and FIG. 3 being an overall side view. [Explanation of main symbols] 1... Vehicle body 2... Lower link 3.

Claims (1)

[Claims] Coulters are pivotally connected to the frame, which is connected to the vehicle body in a vertically movable and transmittable manner, facing each other on the left and right sides of the lower part, and a dredging guide whose tip is located below the coulter is diagonally installed between the coulters. A tillage device characterized in that a rotary cutting blade is provided on the rear end side of the guide.
