Description

[Detailed Description of the Invention] The present invention relates to a fertilization device for a rice transplanter, which has a U-shaped or V-shaped groove cutter with a rearward open cross section connected to the lower end of a fertilizer supply hose.

In a conventional fertilization device for a rice transplanter of this kind, the U is sequentially applied to the mixed deposits of fertilizer and mud that have adhered to the inner surface of the side wall of the furrower through mud and water as a core.
There was a risk that the fertilizer would adhere and pile up completely filling the letter-shaped and V-shaped spaces, causing a phenomenon of fertilizer clogging that would impede the fertilization work. This tendency was particularly noticeable when work was stopped midway through, as the adhered mud, which would have been shaken off by machine vibrations during work, solidified over time.

In view of the above circumstances, an object of the present invention is to provide a device that can reliably prevent the above-mentioned fertilizer clogging phenomenon by adding a simple mechanism.

The characteristic configuration of the fertilization device for rice transplanters according to the present invention, which has been made to achieve the above object, is that it is movable back and forth along the inner surface of the side wall of the furrower, and is stored along the deep inside of the furrower. The scraper is provided so that it can be operated from the outside.

The effects of the present invention having such a characteristic configuration are as follows.

In other words, by providing the scraper, not only can the deposits adhering to the inner surface of the side wall of the trencher be reliably scraped off, but also the provision of the scraper can substantially reduce the cross-sectional area for fertilizer flow. By arranging the retracted position of the scraper along the inner depth of the trencher, the problem of fertilizer clogging can be prevented as much as possible by arranging the storage position of the scraper to be along the inner depth of the trencher. We were able to provide something useful.

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

As shown in FIG. 1, a planting arm 4 is attached via a link mechanism 3 to a transmission case 2 which is connected to a traveling machine body 13 via a link mechanism 1 so as to be operable to move up and down, so as to be driven to swing. A seedling stand 5 is provided in front of the seedling planting arm 4 so as to be slid back and forth from side to side as the seedlings are planted, and a grounding float 6 is attached to the transmission case 2. The fertilizer tank 7 is attached to the support member 8, and the fertilizer supply hose 10 has a cross-sectional shape connected to the lower end of the fertilizer supply hose 10 so that the fertilizer is supplied to the fertilizer feeding device 9 attached to the bottom of the tank 7. A rear-open U-shaped or V-shaped trencher 11 is placed so as to create a trench near the seedling planting location and supply fertilizer to the created trench.
It is attached to the ground float 6 via the plate body 12 so that fertilization work can be performed at the same time as seedling planting work, and
The seedling planting device of a riding rice transplanter with a fertilization device is configured so that it can be used for direct sowing of rice, wheat, etc.

A scraper 14, which can swing back and forth along the inner surface of the side wall of the groove creator 11 and is stored along the inner depth of the groove creator 11, is attached to a horizontal shaft 15 provided between the side walls. Along with the shaft mounting, the groove creator 1
1. A spring 16 is provided at the proximal end portion 14A protruding outward.
is stretched between the groove cutter 11 and the groove cutter 11. In order to operate the scraper 14 against the spring 16, a pulley 18 is provided with a wire 17 fixed to the seedling stand 5, with one end removably pivoted to the top link 1a of the link mechanism 1 on the side of the traveling body 13. It is attached and fixed to the base end portion 14A of the scraper 14 via the scraper 14. Therefore, the raising operation of the seedling planting device A, that is,
The scraper 14 can be operated by utilizing the relative displacement between the top link 1a and the pulley 18 due to the upward movement of the link mechanism 1. A fork-shaped member 19 is connected to one end of the wire 17, and the round bar-shaped locking portion 19A of this fork-shaped member 19 is
It is configured to be freely engageable and detachable from the top link 1a side hook member 20.

Another example will be shown below. One end of the wire 17 attached to the link mechanism 1 is detachably attached to the planting side link mechanism 3, and the planting arm 4
A configuration may be adopted in which the scraper 14 is operated in conjunction with the planting operation.

As shown in FIGS. 5 and 6, a rubber sensitive film 21 is stretched on the upper end side wall of the groove creator 11 in a state facing the internal space, and the sensitive film 21
A limit switch 22, which has an actuating piece 22a interlockably connected to 1, is located on the rear side of the sensitive membrane 21,
The sensor will be used to warn of clogging of fertilizer. A configuration may be adopted in which the limit switch 22 detects clogging and operates the scraper 14.

As shown in FIG. 7, a capacitive proximity switch 23 may be attached to the upper surface of the inside of the fertilizer supply hose 10 away from the fertilizer falling path to detect fertilizer clogging.

If the scraper 14 is constructed with sufficient strength, it can be moved protrudingly into the operating position and the seedling planting device A
It can also be used as a stand to support.
