Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a grooving device of a no-tillage direct sowing machine configured to sow a sowing groove on the ground surface in a non-tillage field, and more specifically, to improve mud soil on the surface. The present invention relates to a grooving device capable of surely engraving a seeding groove on the surface of the ground while removing scraps and the like.

[0002]

[Prior art]

 2A and 2B are explanatory views of a conventional groove making device, in which A is a side view and B is a front view. This grooving device is composed of a grooving wheel 3 in which grooving claws 2 are radially planted with respect to a bearing 1 and a tubular body 5 fixedly provided on a side plate 4 welded to the side surface thereof. It is fixedly provided at the tip of a rotary shaft 12 that is provided so as to project to the side of 11. The cylindrical body 5 covers the rotary shaft 12 protruding from the machine body 11, and is provided so as to surround the peripheral edge of the rotary shaft 12. A guide cover 7 is provided above the grooving device so as to guide the soil that has been flipped up by the grooving wheel 3 rearward.

FIG. 3 is a side view of a “tractor-pulling type no-tillage direct sowing machine” equipped with a conventional grooving device. The machine body 11 is movably supported by front wheels 13 and rear wheels 14, and a tractor T is provided. Are connected to each other via a connecting mechanism T1 so that they can be pulled and moved up and down. The rotary shaft 12 is rotatably linked to the output shaft T2 of the tractor T so that the grooved sheave 3 at the tip rotates against the traveling of the machine body 11. The machine body 11 is provided with a fertilizer application device A, a seeding device B, and a drug application device C. The seeding device B is composed of a seed tank 15, a seed feeding device 16 and a seed dropping cylinder 17, and the seed dropping cylinder 17 is opened to the rear of the groove cutting wheel 3.

In the above-mentioned embodiment, when the machine body 11 is run by being pulled by the tractor T, the seeding groove a is engraved on the ground by the groove cutting wheel 3, and the seed dropping cylinder 17 is attached to the seeding groove a. The seeds that have flowed down are sown. The seeds are flipped up by the slicing wheel 3 and covered with the soil guided by the guide cover 7.

[0005]

[Problems to be solved by the device]

 However, in the conventional grooving device, the mud and straw debris accumulated on the surface of the cylinder 5 which rotates integrally with the grooving wheel 3 are wound around the cylinder 5, and the seeding groove a can be reliably engraved on the surface of the earth. There were no drawbacks.

[0006]

[Means for Solving the Problems]

 The purpose of this invention is to eliminate the above-mentioned drawbacks, so that the soil and straw debris are removed from the seeding groove a while preventing the soil and straw debris from adhering to the peripheral surface of the cylindrical body 5. The purpose of the present invention is to provide a groove making device that can be freely engraved.

That is, according to the present invention, a grooved wheel having radial grooved claws radially fixed to a bearing is fixed to a tip of a rotary shaft which is provided so as to project laterally of a no-till direct seeder, and at the same time, A cylindrical body for covering the rotary shaft is provided on a side surface of the grooved sheave, and an earth-discharging plate is provided upright on a peripheral surface of the cylindrical body.

[0008]

[Action]

 According to this invention, since the soil discharging plate 6 provided on the circumferential surface of the tubular body 5 allows the vehicle to travel while removing soil and straw debris accumulated on the ground surface, the seeding groove a can be surely formed on the ground surface. I can do it now.

[0009]

【Example】

 An embodiment of the present invention will be described with reference to FIG. 1. Reference numeral 11 is a machine body of a direct sowing machine, a rotary shaft 12 is provided so as to project to the side of the machine body 11, and a groove forming device according to the present invention is fixedly provided at the tip thereof. Has been. This grooving device includes a grooving wheel 3 formed by radially grooving grooved claws 2 on a bearing 1 which is fixed to a rotary shaft 12, and a side plate 4 on one side of the grooving wheel 3. It is composed of a fixed cylinder body 5 and an earth-discharging plate 6 provided upright with respect to the peripheral surface of the cylinder body 5. The side plates 4 are for firmly holding the groove cutting claws 2 with respect to the bearing 1, and therefore are preferably welded to both sides of the groove cutting wheel 3. Above the grooving device, there is provided a guide cover 7 for guiding the soil that has been flipped up by the grooving wheel 3 toward the rear.

Since the present invention is configured as described above, when the rotating shaft 12 is rotated while the machine body 11 is running to rotate the groove car 3, the soil and the slurry accumulated in front of the groove car 3 are rotated. Since the debris and the like are removed by the soil discharge plate 6 on the peripheral surface of the cylindrical body 5, the seeding groove a is surely engraved on the ground surface.

[0011]

【The invention's effect】

 As described above, according to the present invention, the soil drainage plate removes the soil and straw debris accumulated in front of the ditching device, so that the seeding ditch can be engraved easily and reliably in a no-till field. It has an effect.
