Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digging machine for hay.

[0002]

2. Description of the Related Art Conventionally, rush plant strains are harder and less likely to rot than paddy rice strains and hinder the next agricultural work and the growth of crops. Therefore, it is desirable to remove them from the field.

[0003]

However, there is no suitable working machine for removing the rush plant stock, and therefore the stock removal work must be carried out manually, resulting in a decrease in work efficiency and There is a problem that the burden is large.

[0004]

According to the present invention, a weeding section for weeding a rush plant, a swing excavating section having an excavating blade disposed below the plant, and a slanting rearward upward transport of the plant. The present invention is to provide a digging machine for digging grass stocks, which comprises: a transporting section for carrying out soil and a scraping section for scraping off sediment from the stock.

The transfer section is composed of a pair of upper and lower transfer chains that are inclined forward and backward and high, and an up-and-down pressing rod provided to face the up-and-down transfer chain. The sedge stock is sandwiched between the two and the upper and lower transport chains are rotated to transport the stock diagonally rearward and upward, and the soil scraping section is located directly below the transport section and is moved horizontally. A plurality of scraping projections are provided on the outer circumference of the extended rotary shaft, and the rotation shaft rotates to scrape off the earth and sand adhering to the igrowth plants being transported by the scraping projections. It has characteristics.

EFFECTS OF THE INVENTION According to the present invention, a weeding section for weeding a rush plant, and a swing excavating section in which a drilling blade is arranged below the strain,
By constructing a rush weeder excavator equipped with a transport unit that transports the plant in an obliquely rearward and upward direction and a sand scraping unit that scrapes sediment from the plant, transporting it with the rock excavation unit in the weeding unit. To the position suitable for excavation work, excavating the soil at the base of the stock by the rocking excavation unit to facilitate pulling out the stock, and pulling the stock diagonally upward and upward at the transporting section, and at the soil scraping section. Since the earth and sand adhering to the plant can be scraped off, the work from the removal of the plant of rush to the removal of the earth and sand adhering to the plant can be automated.

Further, the above-mentioned carrying section is composed of a pair of upper and lower carrying chains which are inclined forward and backward and high and an up-and-down pressing rod provided so as to face the up-and-down carrying chain. The plant is sandwiched between the two and the upper and lower transport chains are rotated to transport the strain diagonally rearward and upward. It can be transported to the upper rear.

Further, a plurality of scraping projections are provided on the outer periphery of a rotary shaft which is located immediately below the conveying section and extends in the left-right direction, and the scraping projections are rotated by the rotation of the rotary shaft. Since it is configured to scrape off the earth and sand adhering to the plant of the rush that is being transferred in the transfer section, it is possible to scrape off the earth and sand adhering to the plant while having a simple structure.
