[Detailed Description of the Invention] The present invention relates to the improvement of a seeding device equipped with a seeding machine at the rear of a rotary, improving the weight distribution between the front and rear wheels of a tractor when attached to a tractor, and eliminating the need for special equipment for various types of rotary. The purpose is to make it more versatile and thereby contribute to reducing production costs.

In the past, various so-called so-called tilling and simultaneous sowing type seeding devices equipped with a seeding machine at the rear of a rotary have been proposed and put into practical use, but in general, the rotary is equipped with a rubber base on the rear cover that constitutes the rotary cover. Therefore, in order to improve the sowing accuracy, it was necessary to remove the rubber sag and separately attach a leveling plate to the rear cover.

In addition, the leveling plate is fixed to the rear edge of the rear cover and is swingable in the front and back directions using the pivot of the rear cover relative to the front cover as a fulcrum, so the length from this pivot to the tip of the leveling plate is a dog. The grounding point of the leveling plate becomes thicker (changes) in the front and back as the rotary plowing depth changes.

In other words, at the maximum plowing depth, the grounding point is the thickest at the rear (
To prevent the seeding machine from interfering with the transition,
It was necessary to install the seeding machine far enough to the rear.

Therefore, this type of tractor has the disadvantage that the weight balance between the front and rear wheels of the tractor is lost.

As described in detail in the embodiments above, in the present invention, the leveling plate located between the rotary and the seeding machine is pivoted to the support rod protruding rearward from the rotary body so as to be swingable around the horizontal axis 6. This eliminates the need to attach a separate auxiliary cover or leveling plate to the rear cover that makes up the rotary cover every time seeds are sown. You can start sowing immediately.

Moreover, the support rod is vertically adjustable via a plowing depth adjustment mechanism, and is equipped with a pair of left and right gauge members, and the support rod is provided with a leveling plate, so the relative relationship between the gauge member and the leveling plate is It is always approximately constant regardless of tillage depth adjustment, and therefore, there is extremely little variation in the position of the grounding point of the leveling plate due to changes in tillage depth.As a result, the position of the seeding machine is generally rotary compared to conventional ones. Therefore, the weight balance between the front and rear wheels of the tractor is stable, and safe work is possible.

In addition, the sowing machine is attached to the support rod via a parallel link mechanism so that it can be raised and lowered freely, so even if the plowing depth is adjusted, the attachment point of the seeder does not change significantly up and down, and the sowing machine is always in the field. This means that the seeding machine moves in parallel following the surface of the seedling, and the conditions such as the seeding posture are constant, making it possible to perform reliable seeding work.

播種機は左右一対のゲージ部−材間にあるので、全体の
前後方向の長さを短縮し重量バランスを良好にできる。
Since the seeding machine is located between the left and right pair of gauge parts and the material, the overall length in the front-back direction can be shortened and the weight balance can be improved.

Furthermore, on both the left and right ends of the leveling plate, there are upper regulating plates that protrude forward to restrict the movement of soil outward in the lateral direction, so that when leveling the ground, part of the field topsoil is placed outside both ends of the leveling plate. There is no longer a situation where the enemy moves and becomes hostile, and the ground can be leveled evenly.

Further, since the upper regulating plate is adjustable in the lateral direction, it can be arbitrarily adjusted according to the tilling width of various rotary machines or the number of seeding machines installed, and is excellent in versatility in this respect as well.
