Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Reiki device for a rotary tiller, in which each of the Reiki rods installed at predetermined intervals in the tilling width direction between the tilling section and the rear cover can be individually attached or removed. Although it is possible to change the crushing rate of surface finely crushed soil, it is possible to change the crushing rate of the surface finely crushed soil.However, by making each Reiki rod independently swingable in the forward and backward direction, it is possible to expect a crushing effect suitable for flying soil clods, etc. 2 The purpose is to do so.

In recent years, rotary machines with Reiki have been attracting attention.

This is because by installing a Reiki inside the tilling cover, large pieces of soil and residual culms fall along the inner surface of the Reiki, and small pieces pass through the Reiki and form a large curtain first. This is because it falls on top of soil clods, etc. and forms the best seeding bed with a large soil mass in the lower layer and finely crushed soil in the surface layer, and also has a good soil crushing effect.

Conventional Reiki devices are fixed to the rear cover, and the pitch of the Reiki rods is constant, and the far and near positions of the tiller remain unchanged. Therefore, it is not possible to change the soil quality of the field or the soil crushing rate (ratio of soil clods of a certain size, for example, 2 cm or less) depending on the type of crops, etc., and in fields with high moisture content, Reiki There were cases where the weighing scale was clogged with soil, resulting in extremely crushed soil.

The present invention was devised in order to solve the problems of the conventional Reiki device, and a rear cover that covers the rear of the tilling section is pivoted to the rear of the main cover that covers the upper part of the tilling section. In the Reiki device of a rotary tiller, in which Reiki rods are installed at predetermined intervals in the direction of A5 between the rear cover and the rear cover, each Reiki rod is independently swingable in the front and back direction on the main cover and is detachably fixed. Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1 to 5, (1) is an upper cut type rotary tiller, which is attached to a tractor (not shown) via a three-point linkage mechanism (2), and is attached to a gear case, which protrudes from the left and right sides of the tiller.

In the first projecting example shown in Figs. 2 and 3, the flanges (c) at both ends of the metal fitting mount (to) are fixed to the flanges at both ends of the main cover (14) with bolts (c), etc. , A metal fitting mount (c) is attached to the lower surface of the main cover 04.

The Reiki rod support bracket is installed on the bracket mounting base (c).
1° are fixed at the same predetermined intervals □, and each of the Reiki rod supporting metal fittings (goods) is located at the holding part (C) and behind the holding part (C) and the holding part (to). It has an arc-shaped insertion hole with the fulcrum at 5. Therefore, the thickness is 10~ made of an elastic material such as a metal wire, a resin wire, or a metal wire coated with Teflon or the like.
The upper end of the 12m1 Reiki rod (A) has a horizontal bend (
), and the KL-shaped part Oυ is connected to the bent part (to), and when the horizontally bent part (to) is rotatably inserted into the holding part @, the IC, L-shaped part 01 is It is inserted into the insertion part using the deformation.

Here, each of the Reiki rods (K and Reiki rod) can be attached to the supporting metal fitting (■) independently (removable, detachable and fixable), and can be freely attached (to) in the direction of the arrows in Figures 2 and 3, i.e., in the front and back directions. It is said to be able to swing freely.

Incidentally, the Reiki rod (A) in the first embodiment may be formed by connecting a single piece of elastic material with bending as shown in FIG. It is better to form a division.

In addition, as shown in Figure 3, it is recommended to install a shielding plate for pilots, etc. across the entire plowing area on the front side of the Reiki rod support metal fittings, from the viewpoint of preventing soil from adhering to the Reiki rod support metal fittings (assets). Desirable.

Figures 5 to 7 show the second and third embodiments of the present invention. The mounting structure is different, and the rest is basically the same as the first embodiment.

In FIGS. 5 and 6, the main cover 04 is formed with a long window (to) in the tiller direction, and a strip-shaped plate (to) that closes this window (to) is used to prevent the main force from leaking out. It is superimposed on the top surface and fixed with bolts (b).

Plate (to) ((in this example, box-shaped mounting bracket)
) are fixed to the plow at predetermined intervals in the tilling width direction,
The upper end insertion part (2) of the Reiki rod (A) is inserted into each of the mounting fittings (A) from below and attached with a fastener (A) such as a bottle or bolt.

Each of the Reiki rods (A) of the second embodiment is able to swing back and forth in the front and back direction due to its own elastic restoring action, and is also capable of being independently attached to and removed from the mounting bracket (1).

In the third embodiment shown in FIG. 17, a plurality of insertion protrusions θυ are attached to the lower surface of the main cover 04 at predetermined intervals in the tilling direction, and the cylindrical part @ to be fitted onto the protrusions Oυ is attached to the rear surface of the main cover 04.
