Abstract

PURPOSE:To favorably carry out overseeding and growth for the partially tilled soil surface by sowing seeds with a seeder before and after a land compacting part with a cultipacker on the tilled soil surface and applying a fertilizer with a fertilizer applicator. CONSTITUTION:Seeds are sown on a tilled soil surface to be tilled with tillage tines 1 using a seeder 2 and compacted with a cultipacker 3. Compacted furrows in the direction of tillage rows are formed on the compacted surface and a fertilizer is applied along the central part of the compacted furrow parts with a fertilizer applicator 4. The fertilizer hardly flows to both left and right sides of the tilled soil and the fertilizer is absorbed in the center of the seeding width of the tilled soil.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a partial tillage device for sowing, fertilizing, etc. while cultivating a pasture or the like in a narrow width.

Prior Art and Problems to be Solved by the Invention When partially cultivating a pasture, the width of the tillage is narrow, and if nitrogen-based fertilizer is applied to the sown area, it will be easily absorbed by the grass in the uncultivated area, and it will spread to the tilled area. The growth of sown grass is delayed, resulting in large differences in growth.

Means for Solving the Problems This invention provides a tilling claw (1
), a sowing device (2) that sows seeds over the tilling width using the tilling claws (1), a cultivar force (3) that compresses the soil surface after sowing, and fertilization only along the center of the tilling width after compaction. This is an oval structure of a partial tillage device including a fertilization device (4).

Function and effect of the invention When partial tilling is performed while propelling the tilling device, the tilling claws (1
), seeds are sown by the seeding device (2) on the tilled soil surface, and the soil surface after sowing is then compacted with a culti packer (co), so that the seeds are compacted on the tilled soil surface. Fertilizer is difficult to move, and since a compaction groove is formed on the compaction surface along the direction of the tilled row, the fertilizer is applied by the fertilization device (4) along the central part of the compaction groove section of the tilled soil. Fertilizer does not easily flow to the left and right sides of tilled soil, and fertilizer can be absorbed mainly in the sowing width of tilled soil.

In this way, the seeding device (2) is used to sow and the fertilization device (4) is used to apply fertilizer before and after the compaction section of the cultivated soil surface by the cultipapper (3), so that the sowing is spread widely over the entire width of the cultivated soil surface. Fertilization can be applied only to the central part of the tilled soil surface width to reduce runoff and absorption into adjacent pastures, and fertilizer can be applied only to the central part of the tilled soil surface width, reducing fertilizer application to the partially tilled soil surface. Good seeding and growth can be achieved.

Example When turning, the partial tilling device (6) connected to the rear of the tractor body is equipped with several tilling claws (1) around the shaft (5) and set to a predetermined tilling width. The partial tillage devices (6) are arranged in several rows at appropriate intervals in the lateral direction, and are transmitted by a transmission device (7). (8) is a tilling cover, and (9) is a leveling plate provided at the rear of the tilling cover (8). fl is the aircraft body, in addition to the tillage equipment W (6), there is also a soil conditioner spraying device (II) that applies soil conditioners such as lime.
, a seeding device (2) that sows grass seeds, a cultipacker (3) that forms concave and convex strips along the rotational direction of the roll to form compaction grooves (a) while compacting the soil surface, and nitrogen-based fertilizer, etc. A fertilizer application device [4] is installed. 0i is a connecting mast that connects to the lower link and top link of the tractor. (The first floor is the input shaft that transmits power from the power take-off shaft of the tractor body.
), the seeding device (2), etc., and the tilling shaft (5).

The soil conditioner dispersing device [II) is for dispersing the soil conditioner over the tilling width of the tilling device (6), and tills the soil surface after dispersing with the tilling claws (1). It has a potper 04 at the top that accommodates the soil conditioner, and a pipe (1!1) that guides the dispensed soil conditioner downward is visible in front of each tilling device (6). Seeding device (2) And the fertilizer application device (4) etc. are also equipped with potspar (1e (■ and pipe fl) in the same way as the spreading device (1)
[l F+91], and is provided corresponding to each tilling device (6). Among these, the sowing device (2) is configured to sow the seeds over the entire width of the tilled soil (b), and the fertilization device (4) is configured to apply fertilizer only to a narrow central portion of the width of the tilled soil.

The culti packer (3) is rotatably provided around the horizontal axis 12+1 with respect to the tip of the support arm 12 [] which is vertically swingable with respect to the machine body (10), and has several triangular irregularities on the roll circumferential surface. The structure is such that striations are formed to form suppression grooves (a) on the soil (b) surface. (c) is grass grown on existing pasture land.
