Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a weeding rotor operation method of a weeding rotor device for weeding weeds etc. that have grown between the rows after planting seedlings using a rice transplanter. be.

Conventional technology Traditionally, when rice was planted using a rice transplanter, weeds would grow between the rows.
In order to eliminate the poor growth of seedlings caused by these weeds, it was necessary to remove the weeds.

Problems to be Solved by the Invention By the way, the above-mentioned weeds in rice cultivation are conventionally removed by spraying herbicides, but the spraying of the herbicides does not only adversely affect the seedlings themselves, resulting in a decrease in crop yield. (There is a risk that it may have an adverse effect on the human body. Therefore, in recent years, rice plowing carts and weeding rotors have been reviewed, and so-called organic farming has become more active. However, in organic cultivation, straw,
Since a large amount of coarse organic matter such as rice husks and residual plants is used, there is a lot of toxic gas generated from the coarse organic matter in the rice field and soil after planting, and the plowing wheel and weeding rotor alone are insufficient to degas the toxic gas. is insufficient, and problems such as poor root establishment and root rot cannot be avoided.

In view of the above-mentioned circumstances, the present invention aims to prevent the generation of toxic gases,
It is an object of the present invention to provide a weeding rotor working method that can eliminate problems such as poor root attachment and root rot.

Means for Solving the Problems In order to achieve the object, the present invention provides a mobile agricultural machine to which a weeding rotor device is detachably attached, and at the same time performs weeding work with the weeding rotor device, a liquid degassing agent is applied to the soil. The gist is to disseminate.

Operation: At the same time as the weeding rotor device starts inter-tilling and weeding between the rows, a liquid degassing agent is sprayed onto the soil.

Embodiment An embodiment of the weeding rotor working method of the present invention will be described based on the drawings.

In the figure, a weeding rotor device B is connected to a rolling spring a stretched in a V-shape in plan view by the expansion and contraction of a hydraulic cylinder (not shown) via a parallel link mechanism 1 arranged behind the main machine A of a riding rice transplanter. It is removably attached so that it can move up and down while maintaining a horizontal position due to the balance effect. The machine A used here is equipped with a storage tank 2 at the front of the machine to store fertilizer (not shown) so that liquid fertilizer can be sprayed at the same time as the rice planting work. At the same time, the fertilizer in the storage tank 2 is sent from the storage tank 2 via the hose 3 and the pump 4 to the fertilization hose 5.5 and the fertilization nozzle 6.6 at the rear of the aircraft. has been done.

In addition, in the weeding rotor device B, a work machine side hit 8 is detachably connected to a machine side hit 7 provided on the free end side of the parallel link mechanism 1, and a rolling fulcrum shaft 8a is attached to the work machine side hit 8. A frame 9 is connected via the frame 9. moreover,
A rotor portion R consisting of a plurality of rotors 10, 10, . . . arranged so as to be located between the rows after planting is connected via the frame 9. As shown in FIG. 2, this rotor portion R is rotated by power being transmitted from a PTO shaft (not shown) installed in the machine A to a gear case 12 and a transmission case 13 via a universal joint shaft 11. It is configured to be driven to perform weeding work. In the figure, 14 is a groove cutting ring;
15. 15... is a weeding board for preventing seedlings from being caught in front of each of the rotors 10, 10..., and 16 is a cover for preventing scattering of mud, which covers the full width of the upper rear side of the rotor section R. The connecting plate 16a is located at the rear side and faces obliquely downward, and is fixed to the transmission case 13 via a connecting plate 16a whose one end side is fixed.

Furthermore, the weeding rotor device B used here includes:
It is configured so that a liquid degassing agent C can be sprayed onto the soil after weeding at the same time as the weeding work. That is, a liquid degassing material C is stored in the storage tank 2, and a tool bar 18 is horizontally suspended on a fertilization frame 17 that is integrally connected to the frame 9 in the rear direction.
There is a fertilizing nozzle 6.6 located behind each rotor part R.
... are provided, and the liquid degassing agent C stored in the storage tank 2 is sprayed onto the soil through the fertilization nozzles 6,6,.... In addition, the discharge ports 6a, 6a of the fertilizing nozzle 6.6 used here.
... has a structural shape and is configured so that the liquid degassing agent C can be widely sprayed.

Liquid degassing agent C is a type of bacteria that multiplies in large quantities by feeding on toxic gas generated from coarse organic matter and eliminates gas in the soil, and does not have any adverse effects on seedlings or the human body.

4 and 5 show a second embodiment of the present invention,
The fertilizing nozzle 26 is designed so that the liquid degassing agent C sprayed from the fertilizing nozzle can be spread more widely.
The discharge ports 26a, 26a... are branched into a plurality of branches, and the degassing agent C is sprayed before intercultivation by the rotor part R, and the degassing agent C after being sprayed is stirred together with the soil by the rotor part R. The degassing agent C is configured so that the action of the degassing agent C is exerted on the soil after inter-tilling without mutual selection.

In the above configuration, the planting section (A) of the riding rice transplanter (
When the weeding rotor device B is connected to start work, the power from the PTO shaft (not shown) of the machine A is transferred to the universal joint shaft 11, the gear case 12, and then the transmission case 13. The information is transmitted to the rotor portion R of the weeding rotor device B.
is forcibly rotated to perform inter-tillage and weeding between each row, and at the same time, the liquid degassing agent C stored in the storage tank 2 is pumped through the hose 3 and fertilization bowl 5 by the action of the pump 4.
, 5..., and further, the fertilization port 5,
The fertilizer is sprayed from 5... to the inter-row areas via fertilizer nozzles 6, 6.... In addition, the weeding rotor device B is the main machine A.
Since the machine A is connected to the machine A so that it can roll freely via rolling springs a and a, it is always maintained in a horizontal position regardless of the inclination of the machine A, and the inter-tillage and weeding operations are carried out at a uniform depth between each row. be exposed. Therefore, not only will there be no gaps between rows during tillage and weeding, but also the degassing agent C can be applied to the deep layers of the soil. As a result, the gas generated in the upper layer of the soil is removed from the claws of the rotor 10 at the same time as inter-tilling and weeding.
The gas in the deep layer can be reliably extinguished with the liquid degassing agent C that is sprayed on the soil after intercultivation.

By the way, since the weeding rotor device B in the present invention is pulled by the main machine A of the riding rice transplanter, it can be used for intermediate tillage and plowing in paddy fields.
The functional characteristics of this machine A can be used as is for weeding and spraying work, allowing efficient inter-tillage, weeding and spraying work.

In other words, it is impossible to work in paddy fields with a tractor-drawn weeding rotor device, but since the present invention uses a riding rice transplanter that is a vehicle exclusively for paddy fields, it does not tread on standing crops with its wheels during work, nor do it in fields. It does not damage the face needlessly, and
The interplant transmission device, which is standard equipment on the riding rice transplanter, allows the rotational speed of the rotor section R to be adjusted to the optimum speed according to the state of weeds in the field.

The present invention can also be applied to walking-type rice transplanters, weeding rotor-only machines, etc., and can also be used for inter-tillage, weeding, and spraying operations not only in paddy fields but also in field crops.

Effects of the Invention As described above, the present invention provides a mobile agricultural machine equipped with a weeding rotor device that is removably attached, by simultaneously performing weeding work with the weeding rotor device and spraying a liquid degassing agent onto the soil. Weeding and degassing agent spraying can be done at the same time, improving work efficiency.Furthermore, the degassing agent can be applied deep into the soil after weeding, preventing poor root establishment and roots. It is possible to prevent rot and the like and improve the rooting of seedlings, thereby increasing yield and quality of crops.
