Description

[Detailed description of the invention] This invention relates to a cutter device for a spiral tillage rotor that is fitted onto the tillage shaft of a tiller. The object of the present invention is to devise a cutter device that can proactively prevent the remaining tillage from becoming entangled, and the device of the present invention remotely achieves the above-mentioned purpose by shredding the remaining tillage with the cutter device. , the gist is that the left and right cylinders rotate about the same axis in the left and right spiral tillage rotors, which are respectively fitted to the left and right ends of a tillage shaft rotatably supported by the tiller's gear box. Both cylinder type cutters are equipped with rotary blades that are arranged side by side along the flange plate and shaft cylinder of the spiral tillage rotor and have a cutting edge, and fixed blades that are supported on the gear box. It consists of a blade.

An embodiment embodying the technical means of the present invention will be described below with reference to the drawings.

In the drawings, Ct indicates the entire tiller, which mainly includes a gear box a, a tilling shaft b1, a support tube c1, an engine E, etc.

Next, to explain the main parts of the present invention, /a, /b in the figure
are left and right spiral tillage rotors (hereinafter simply referred to as rotors).

), rotor shaft cylinder parts 2a and 2b of the rotors /a and /b are fitted to the left and right end parts Ra and Rh of the tillage shaft, respectively.

Note that 3a and 3b are flange plates and 4a fixed to the inner ends of the shaft cylinder parts 2a and 2b, respectively.

4b is an opening formed inward of the rotor /a, /b.

Next, the cylinder type cutter device of this example will be explained. 5a and 5b are the flange plates 3a.

3b and the left and right rotary blades are arranged side by side along the shaft cylindrical parts 2a, 2b, and have cutting edge edges 6a, 6b.

Denoted at 7a and 7b are left and right fixed blades supported 8 on the gear box a, and each time the blades engage with the rotary blades 5a and 5b, the remaining cultivated material W such as straw is shredded.

Next, the functions and effects of the embodiment configured as described above will be specifically explained.

Now, when tilling work is performed using the tiller Ct equipped with the cutter device of this example, the left and right rotors /a.

In the tiller Ct of this example, a cutter device consisting of rotary blades 5a, 5b and fixed blades 7a, 7b is inserted in the rotors /a, /b. Because of this, the remaining cultivated material W is sequentially shredded by the same cutter device and removed from the rotor.
It is well recognized that the remaining tillage W such as straw turns into large lumps in a, / b and does not affect the tilling function.

In other words, the present invention is based on the configuration described in the claims for utility model registration, which exhibits the effect of preventing the left and right rotors from being filled with residual tillage, and moreover, the cutter device is capable of reducing tillage. is also extremely easy,
The present invention can be said to be a device that can improve the tillage function of a tiller as a cutter device for a spiral tillage rotor.

[Brief explanation of drawings]

The drawings show one embodiment of the present invention, FIG. 1 is a schematic side view showing an embodiment of the present invention, FIG. 2 is an enlarged sectional view taken along the Y2-Y2 line in FIG. 1, and FIG. It is an enlarged sectional view taken along the Y3-Y3 line in the figure. [Explanation of symbols] In the drawings, Ct indicates the entire tiller, which mainly includes a gear box a, a tilling shaft b, a support pipe C, an engine E, and the like. la. Reference numeral 1b denotes left and right spiral tillage rotors (hereinafter simply referred to as rotors), and the shaft cylinder portions 2a of the rotors 1a and 1b correspond to the left and right ends Rb of the tillage shaft. 2b are fitted respectively. 5a and 5b are the flange plates 3a and 3b and the shaft cylinder portion 2;
There are left and right rotary blades arranged side by side along a and 2b, and have cutting edge edges 6a and 6b. 7a and 7b are left and right fixed blades supported 8 on the gear box a.

Claims (1)

[Scope of utility model registration request] Left and right cylindrical cutters, which rotate about the same axis, are attached to the left and right spiral tillage rotors, which are respectively fitted to the left and right ends of the tillage shaft, which is rotatably supported by the tiller's gear box. At the same time, the double cylinder type cutter includes a rotary blade which is arranged side by side along the flange plate and the shaft cylinder part of the spiral tillage rotor and has a cutting edge;
A cutter device for a spiral tillage rotor, comprising a fixed blade supported by the gear box.
