均平を保持できない問題があった。(Prior Art) Japanese Patent Laid-Open No. 56-15605 is known as a prior art. This is to attach an apron to the center of the rear edge of the cover of the machine frame via a cross universal joint, and to the left and right around this cross universal joint. It tilts and rotates backward. The disadvantage of this is that the universal joint mounting point is an absolute fixing point and can only be tilted left or right or folded backwards, so if the tractor wheel gets stuck in a recess, the apron mounting fixing point will move the tractor forward. There was a problem that the absolute height of the apron was regulated with respect to the direction to act to scrape the scraping surface or uneven pressure was applied, and the water average flatness could not be maintained on the scraping surface.

させるのである。(Means for Solving the Problem) Therefore, in the present invention, a pair of swing links are provided at the rear edges of the side covers, and elastic pressure means is further provided on the upper surface of the leveling device so that the tertiary link can be performed in the traveling direction with respect to the machine frame. While swinging originally, a constant pressure is constantly applied to form a clean hollow surface.

形成するものである。(Operation) When the machine frame is tilted, both ends of the leveling device are independently moved up and down by the pair of swing links provided on the left and right, and the machine frame is elastically supported by the machine frame. A uniform horizontal pressure is applied to form a clean and scratched surface.

付け部を下げて均平装置がしろかき面Ｄに密着する。A pair of brackets 15 are provided behind the machine frame A, and a slidable support rod 5 is arranged above the brackets 15. The lower end of the support rod 5 is connected to the upper surface of the ground leveling plate 1, and a coil-shaped compression spring 6 is provided to form an elastic pressure support device. The leveling device B is elastically supported. The swing link 3 is interposed between the link brackets 8 attached to both ends of the rear of the machine frame A and the leveling device B, and the link bracket 8 and the swing link 3 are provided with tension springs 12 between them.
During normal work, the leveling device B and the attachment portion of the swing link 3 are lowered to bring the leveling device into close contact with the scraping surface D.

のものを簡潔に構成したものである。For example, as shown in FIG. 3, when the left side of the tractor enters a convex surface, the machine frame A inclines, but at this time, the leveling device B acts on the mud surface so that the back pressure action tends to be maintained horizontally. Works.
This horizontal holding action is absorbed by the swingable variable amount of the left and right swing links 3 to level the mud surface. In this way, the leveling device B always performs a water average leveling action with respect to the machine frame A while horizontally or independently inclining vertically. The support bar 5 is provided with a plurality of holes for varying the compression force of the compression spring 6, and keeps the leveling device in a desired constant pressure state. The connecting rod 7 and the handle 11 are fixed to the support frame 5 by fixing the connecting frame 13 via the connecting rod 7 by operating the handle 11.
To regulate the operation of the leveling device B to regulate the operation of the leveling device B, or to perform the scraping work while releasing the fixed state and maintaining the constant pressurization state in the forward direction. Is a simple composition.

・播種等に最適の状態にすることができるものである。(Effect) With the configuration as described above, even if the tractor and the machine frame A are tilted in the front-rear direction and the left-right direction, the leveling device B always keeps the horizontal position with respect to the scraping surface D and applies a constant pressure. Therefore, the influence of the unevenness of the cultivator E on the scraping surface D can be suppressed, and the optimum state for transplanting, sowing, etc. can be achieved.
