Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a trench-making device such as a seeding machine, and can be applied to a device such as a seeding machine or a transplanting machine that sprays a soil disinfectant.

Problems to be Solved by the Invention When a chemical solution is sprayed on the soil surface during seeding work using a seeder, if a trench is made using a trencher immediately after the chemical solution has been sprayed on the soil surface, the soil may become It adheres to the groove making device and makes it difficult to make grooves accurately.

Means for Solving the Problem This invention provides a means for spraying the soil part of the trench at a position opposite to the front side of the trencher (1) that creates trenches on the soil surface and within the spraying range of the chemical solution from the soil disinfection chemical nozzle (2). A groove-making device such as a seeding machine is configured with a cover (2) to prevent liquid from scattering.

Function and Effect of the Invention As the aircraft advances, a chemical solution is sprayed from the chemical solution nozzle ■ onto the soil surface to disinfect the soil surface. Since the soil part after passing through the cover (■) is made by the trencher (1), the groove is created by the groover (1), so that the soil moistened with the chemical solution does not adhere to the trencher (1), and the trench can be created accurately. Moreover, adhesion of chemical solutions to seeding can be reduced.

Example In the illustrated example, 2) is the machine frame of the fertilizing and seeding machine, which is detachably connected to the coupler 6) of the tractor 6). A soil disc e),
A fertilization pipe 0 is provided corresponding to the rear of the soil disk (8), and fertilizer is supplied from the upper fertilizer hopper 0 and is configured to be buried in the soil. The seeding machine is installed at the rear of this, and includes a seed hopper (■) that accommodates the seeds from the furrower (01) to make a furrow on the soil surface, and a pipe (O1) that guides the seeds in this hopper (■) to the furrow on the soil surface (a film that covers the sowing soil surface). The mounting frame υ, which is equipped with a reel ■ and a pressure roll [Co., Ltd.] that suppresses the film-covered soil surface after sowing, can be raised and lowered with respect to the machine frame by a four-point link mechanism (up and down) parallel to the top and bottom. It is set up.

The groove cutter ■ has a mounting part ω at the front end that can be moved up and down with respect to a mounting member ■ integrated with the mounting frame ■, and a cover ■ is integrally provided on the front side of this mounting part ω. The groove is sloped downward from the side toward the right and left ends, and is provided with an appropriate width, and a cover is provided on the rear side of the groove to prevent the chemical solution from scattering toward the side of the groove creator ω.

The film reel ■ is a roll of mulch film, and has a seeding hole in the part facing the furrow machine ω, and as the machine moves forward, the film is sequentially fed out to cover the soil surface immediately after the furrow has been cut. It becomes. The seeding pipe 0 is configured to extend upwardly facing the seeding hole of the mulch film at the rear of the trencher (2) and to be able to sow seeds.

The nozzle ■ is located on the upper side of the cover ■ and is installed to spray the chemical onto the soil surface, and is communicated with the chemical tank @ mounted on the machine frame via the hose ■ via the pump mortar, and is sprayed at an appropriate pressure. It is structured as follows.

As the machine moves forward, the soil is plowed with the plowing claws (■), and the pipe is used to apply fertilizer to the rear side of the tilling disk (). On the rear side, the chemical solution in the tank @ is sprayed onto the soil surface from the nozzle (■) via the hose (■) by driving the pump mortar. The part with the cover ■ is in a state where the chemical solution is not sprayed, and this part is covered with a groove making machine (υ) and covered with mulch film from above, and the sowing pipe ■ is used to sow seeds into the groove part from above, and then If there is a change in the soil surface unevenness in the 6-crop trench where compaction is performed using the compaction roll 0 on the side, the fertilization pipe ω and the cover ■
, nozzle ■1. The multi-fill reel ■, seed seeding device ■, seeding pipe surface, pressure roll 0, etc. move up and down via the four-point link mechanism ω, and the groove cutter ■ and cover ■ also move up and down at the attachment point (to). It is designed to be able to quickly adjust to the height relative to the soil surface.
