Abstract

The present invention was filed on September 21, 1998, filed by "Applicant of the Rotary Plow for Weight-moving Tractors" and "Football Tank for Tractors with Small Left and Right Rolling" and "Rotator Mounting System". As an application for improvement of the horizontal device and structure of a tractor work machine including the devise of a width adjusting device, it is possible to move up, down, left, and right when it is not equipped in the structure of the work machine coupler of the tractor. When one of the two lower couplers of the workbench is inserted into the lower coupler of the work machine, the other one does not move up and down. , The present invention is to attach the hydraulic cylinder to the side of one lower coupling unit of the tractor mounting portion of the device including the above three devises to combine the working machine In order to solve the overload of the rotary mounting unit rolling up and down about the axis, which is the main technical idea of the three designs, a device for adjusting the height of rolling is added to the upper and lower left and right ends of the slide stand of the tractor mounting unit. It is a very useful design to prevent excessive rolling.

Description

Horizontal device and structure of tractor work machine

The present invention relates to a work machine mounting device for mounting a tractor work tool (including all work devices mounted on a three-point link of a tractor for paddy or field cultivation) to a tractor, in particular, a work machine. It is possible to adjust the degree of rolling height of the tractor, and when attaching a work machine to the tractor, it relates to a tractor work machine leveling device that can easily mount the work machine by detaching one of the two hooks (hook).

In case of Korean Utility Model Registration Nos. 88-12926 and 98-12503, the horizontal sailing device consisting of a rotary mounting part and a tractor mounting part connected so that it can be rotated by a shaft when the working machine is mounted is attached to the work machine separately. Even if it is tilted, the level of the work machine is always maintained so as to obtain flat tilling. The main technical idea of the 3rd application of September 21, 1998 of the same applicant is to rotate the rotary mounting unit and the tractor mounting unit under the mount. It reduces the overload of force applied to the shaft to prevent excessive rolling, and adjusts the lower coupling part of the rotary mounting unit with the handle so that it can be easily mounted regardless of the working width of the machine, and it is possible to separate the center of gravity of the machine. Filed by adding a moving part of.

However, in the above design, when the work machine rolls up and down due to the self-load of the attached work machine and the flow of the tractor, the work traces generated by the up and down rolling of the work machine remain, thereby reducing the effect of attaching the work machine horizontal device. . The gun was attached to the gun to relieve it, but there was a closure that caused the adverse effect of worsening the rolling of the work machine. In addition, when attaching the work machine to the three-point link of the tractor, the two lower link structures of the tractor allow the machine to flow up and down and left and right, but once one side is inserted into the lower link of the work machine, the work machine does not move horizontally. In the case of unstable or slanted slopes, the tractor had to be moved back and forth to level the machine and then inserted into the other link.

Therefore, in the present invention, the tractor mounting unit and the tractor mounting unit connected to the rotary mounting unit by the shaft can be rotated, and the shaft can move left and right along the slide unit. The rolling height adjustment part is formed on the top of the slide mount of the tractor mounting part, so that the degree of rolling of the work machine mounted on the rotary mounting part can be arbitrarily adjusted by the user, which is suitable for the bending and soil of the soil to be worked. It is possible to work and to automatically adjust the rolling (Rolling) occurring during the operation by one adjustment, and all the attachments used to attach to the three-point link of the tractor, as mentioned above, because the difficulty in attachment Attach the hydraulic cylinder to one side of the lower coupler of the tractor mounting unit to The effect of facilitating the adhesion, regardless of the state of the working machine in a tractor and increase their effectiveness by using, in addition to the horizontal work machine apparatus is excellent devised.

Referring to the configuration of the subject innovation in detail as follows.

Figure 1 is an exploded perspective view for showing the structure of the rotary mounting device of the present invention, the present invention is a rotary mounting portion 10 consisting of a set of rotary lower coupling 11, rotary center of gravity adjustment unit 12, slide 13 ) And a tractor mounting unit (20) consisting of a set of tractor lower coupling units (21), a tractor weight center adjusting unit (22), and a slide unit (23) so that the tractor mounting unit (20) can be rotated by the shaft (30). In the upper portion of the tractor mounting portion 20 on the slide table 23 on both sides of the insertion nut 52 and the guide tube 53 is formed to form a b support 51, the threaded portion 55 is formed at the bottom Insert the handle 54 into the nut nut 52, the end of the handle 54 is inserted into the c guide hole 59 formed on the top of the toll height 56, and fixed by the nut 57, the Insert and fix one side of the guide rod 58 to the nut portion 60 formed on the upper end side of the rolling height table 56 and the other The guide tube 53 inserted into a pair of roll height adjustment unit 50 is configured by a formed of the a stand (51) side is formed.
