Description

[Detailed Description of the Invention] This invention relates to a tilling section coating device for a tilling machine, particularly a center drive type tilling machine.

Conventionally, this type of tilling machine is provided with a scattering prevention cover and a suitable mud removal sheet for the purpose of preventing mud and soil clods from scattering in the front and rear directions, and preventing mud from adhering to the cover of the machine.

By the way, it is preferable that the scattering prevention cover and mud control sheet be configured so that their positions can be changed to adapt to the purpose of use of the tilling machine (for example, Japanese Utility Model Publication No. 39-28879). There are some that are movable.

However, all of these devices generally have complex structures, resulting in high costs, and have various drawbacks, such as the need to adjust the position of each part to suit the work.

Therefore, this invention proposes a tilling section covering device for a tilling machine that eliminates these drawbacks.The main purpose of this device is to attach an auxiliary cover to the movable cover on the rotary part, and to It is an object of the present invention to provide a tillage part covering device which has a simple structure and can easily obtain a posture according to the working situation by supporting the cover with a plastically deformable guide rod.

An embodiment of this invention will be described below with reference to the drawings.

In Figs. 1 and 2, the tilling work machine 1 is shown as a center drive type, and the cover 3 covering the tilling section 2 has a fixed cover 4 fixed to the machine body, and a hinge or the like as appropriate to this fixed cover 4. It consists of a movable cover 5 whose outer end can be rotated by being connected by a movable cover 5.

A platform 6 is formed on the upper surface of the movable cover 5, and a bottle 7 is horizontally protruded from the platform.

A notch body 8 is constructed, one end of which is pivotally supported by the pin 7. The notch body 8 is formed with a number of grooves 9, and an engagement pin 10 is inserted into any of the grooves 9. By selecting , the vertical angle of the movable cover 5 can be adjusted and fixed at an appropriate angle.

Further, on the back side of the movable cover 5, an auxiliary cover 11 made of an elastic flexible material such as rubber is held in a pinched manner by an appropriate number of guide rods 12 from a lower position, and at its free end, the auxiliary cover 11 is made of an elastic flexible material such as rubber. 5 and guide rod 12
It is provided to extend slightly further.

Each guide rod 12 has an auxiliary cover 11 between it and the movable cover 5.
It is made of a material that has enough strength to sufficiently support the curvature, and to be able to plastically deform it into an appropriate shape with appropriate physical force when the required degree of curvature is required, and to maintain the curvature. be done.

This invention has the above-mentioned structure, and by appropriately plastically deforming the guide rod 12 with arm force according to the work situation, the free end of the auxiliary cover 11 can be similarly deformed.
2, so that the scattering of mud can be prevented at all times in an ideal state, and by making the guide rod 12 free to plastically deform in the vertical and horizontal directions, Not only can the side of the auxiliary cover 11 be adjusted, but also the cover posture can be adjusted in the rear and front parts.
Therefore, the effects of the front cover and rear cover can also be expected.

Furthermore, the combination of the movable cover 5, which can be rotated and fixed at an appropriate position, and the auxiliary cover 11 supported by the guide rod 12 allows the entire cover to be easily adapted to the ridge width without the need for any tools. Seshime and auxiliary cover 1
1 also has the advantage of being able to be shaped into an optimal shape depending on the work, and in addition, the rotational displacement of the movable cover 5 can smoothly scatter and flow the soil to the sides of the machine, making it suitable for a wide range of other works such as ridge-raising. This means that it will be possible to respond to

In some cases, when the guide rod 12 is installed protruding from the vicinity of the machine frame, the usual cover attached to the work machine is not necessarily necessary, and even if it is necessary, it will only be a small piece.
Therefore, the practical effects are great, such as the material required for this can be greatly reduced.
