Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cultivating part support base which makes it possible to safely and easily attach and detach a cultivating part of an agricultural tractor, and which can be attached to any manufacturer and various tractors. .

2. Description of the Related Art In addition to a tillage section K, commonly called a rotary, a rear tractor for agricultural use is provided with various kinds of work such as a harrow for scraping, a broad caster for spreading fertilizer, and a rear bucket for carrying work. The work equipment has been changed. Most of them attach / detach the tractor and the working machine by re-fitting a link called a three-point link. In recent years, some auto-hitch systems that can be attached / detached while sitting in the driver's seat have come to market.

[0003] In particular, the weight of the tilling section is as heavy as several hundred kilograms, and mounting and dismounting work other than the automatic hitch method is performed manually by descending from the tractor. The hitch is rusted, and if the work equipment is tilted, it will not come off easily, and the work is done by kicking with a foot or hitting with a hammer. Since the tilling part was heavy and unbalanced, it fell down in the front-rear direction at the moment of removal, so it was necessary to always work side by side with danger. In addition, it was difficult for one person to do this because two people took the two parts to raise and lower the tip of the tilling section to adjust the hitch.

[Problems to be Solved by the Invention] A problem of attaching and detaching a work machine is how to stand the work machine in a detached state. In most cases, it will tilt back and forth at the point of disengagement, which will take time for the next installation. If the tractor and the cultivation unit maker develop together, whether it is an auto hitch type or a three-point link type hitch, it is possible to attach a stand that matches the cultivation unit and produce it. Are too many types and will be very difficult to produce. In addition, it is even more difficult to attach to a conventional tilling part currently used.

Accordingly, the present invention aims to provide a cultivation section support stand which can be attached to almost all cultivation sections K regardless of the manufacturer, regardless of the new or old cultivation section, and which is safe and easy to attach and detach. .

[Means for Solving the Problems] The configuration of the present invention will be described with reference to the drawings. The rough perspective view of FIG. 2 is a tilling unit K connected to a tractor commonly called a rotary. The present invention is applicable to all manufacturers. It has been found to be sturdy enough to support the entire weight and to be installed in a common location for all models, so that it can be mounted on the tillage section of the model.

[Embodiment] As is evident from FIGS. 1 and 2, the present invention utilizing the two locations, that is, a solid tube and a place always present in all models, has the following structure. One receiving plate 1 is adapted to receive the conductive tube D with a substantially rectangular cross section so as to be attached to the left and right side surfaces of the conductive tube D, and the other holding member 2 has the same shape. It is to be tightened with bolts and nuts. Here, the receiving plate 1 having a substantially rectangular shape may have a substantially semicircular or flat cross section. The shape of one presser 2 is also substantially semicircular in cross section, and can be tightened with bolts and nuts. It is also possible to directly tighten the presser 2 itself using a U-bolt. What is convenient is that if a rubber plate is sandwiched between the receiving plate 1 and the presser 2, the rubber plate will not slip easily and will not be damaged.

The connecting rod 3 is connected to the receiving plate 1 at the upper part, and the lower part has a length reaching below the center of the gear case.
Because the gear case G is outside the length of the
In the shape of, the lower portion is located outside the upper portion, and eventually, it is necessary to perform a process of bending or bending outward at an appropriate location between the upper receiving plate 1 and the lower gear case G. However, the shape is not specified. A hollow shaft having a pin hole is provided in a portion below the connecting rod 3.

A plurality of pin holes 5 are formed in the riser tube S3 of the stand S so that the pins 6 can be inserted into the hollow shaft 7 below the connecting rod 3, and the pins 6 can be inserted and fixed at a desired height. Under the stand S, left and right feet are provided in the front and rear directions of the tillable portion, the length of which is required so that the tillage portion does not fall. The foot S1 is a stretchable foot S
2 and foot S1. The tip of the foot S2 may be the wheel S4.

Next, regarding the adjustment of the installation angle of the tilling part K,
Referring to FIG. 3, a screw 10 is provided below the connecting rod 3 so that the screw 10 can be freely inserted and removed by turning in the direction of the gear case G at a position avoiding the hollow shaft 7. This position is attached to the outside of the connecting rod 3 in the drawing, but the same effect is obtained even inside. An abutment plate 9 is attached to the connecting rod 3 with play provided on the upper portion of the screw 10 so as to swing in the direction of entry and exit of the screw. The backing plate 9 prevents damage to the gear case G by means of the screw 10. Even if the backing plate 9 is removed and directly applied to the gear case G, the same effect can be obtained, although the flaw is damaged.

[Operation] In order to mount the tilling part support base of the agricultural tractor to the left and right side surfaces of the conduction pipe D, it is easy to connect the tilling part to the tractor in advance and mount it. First, the support plate 9 at the lower part of the connecting rod 3 or the direct screw 10 for removing the support plate is positioned at the lower part of the gear case G, the upper receiving plate 1 is applied to the conductive tube D, and one holding tool 2 is placed on the opposite side. Fix both sides with bolts to the extent that they do not move loosely. Next, the tractor is started, the tilling part K is raised, the stand S is inserted into the hollow shaft 7, and the pin 6 is inserted and fixed in the pin hole 5 at a height where the entire tilling part K does not touch the ground. Next, the stand S is gently lowered to just below the ground. Screw 1 so that stand S is properly grounded
0, the abutment plate 9 or the direct screw 10 slides on the grounding surface of the gear case G to determine a correct inclination angle. Finally, the receiving plate 1 and the presser 2 are fixed with bolts so as not to move firmly. Lower K to touch the ground. In this state, even if the tilling portion K is removed from the tractor, whether the automatic hitch method or the three-point link method is used, the state does not change, and subsequent mounting can be easily performed.

[Effects of the Invention] As described above, if the tilling part support of the present invention is adjusted in advance and correctly mounted on the tilling part of the tractor, the tilling part can fall or fall back and forth at the moment the tilling part is removed. It can be safely removed without damage to the limbs because the support with the stand supports without changing. Further, when the tilling part is mounted on the tractor, the tilling part is kept in a detached state, so that the tilling part can be easily mounted alone without adjusting the angle and without renting. Further, since the present invention can be mounted on both sides of a sturdy place of the conduction tube D and the gear case G, which is a place that can be commonly used in most models, it can be mounted on almost all models regardless of all manufacturers and new and old models.
