本発明は、耕耘、耕起、培土等の各種の対地作業に用い
られる農用トラクタの作業装置取付部構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching a working device to an agricultural tractor used for various types of ground work such as plowing, plowing, and soil cultivation.
農用トラクタ用の作業装置には、二点リンク機構を介し

いては、いずれのタイプの作業装置をも選択的に、かつ
、ローリング自在に装着できることが望ましい。There are two types of working devices for agricultural tractors: those that are attached via a two-point linkage mechanism and those that are attached via a three-point linkage mechanism. It is desirable to be able to selectively and roll the device.

ない、 又は、たとえ、取付けられたとしても、リンク
機構ローリングや昇降動作が他方のブラケットに干渉さ
れるからである。To do this, we need a two-point link bracket that is rotatable around the front and rear axis and to which the lower link of the two-point link mechanism can be attached, and a three-point link for the pair of left and right lower links in the three-point link mechanism. It is necessary to equip a fulcrum pin mounting bracket, and in the past, the structure was such that both types of brackets could be selectively attached and used. This is because if a general standard specification rather than a special one is used as the link mechanism for both types, it is impossible to install both types of brackets without mutual interference due to their position, or even if they are installed, This is because the rolling and lifting movements of the link mechanism are interfered with by the other bracket.
従って、従来の農用トラクタにおいては、両種作業装置

両種作業装置の付は替え作業が面倒かつ非能率的であわ
、シかも、両種ブラケットが着脱式である故に、取付構

ブラケットの取付は強度に不安定性がつきまとうといっ
た欠点があった。Therefore, in conventional agricultural tractors, it is necessary to replace the brackets instead of attaching both types of working devices.
Attaching both types of work equipment can be troublesome and inefficient to replace, and since both types of brackets are removable, not only does the mounting structure become complicated, but it also causes problems such as insufficient tightening of the mounting bolts.
Bracket installation has the disadvantage of being unstable in strength.
本発明は、かかる従来欠点を解消しようとする点に目的
を有する。The present invention has an object to overcome such conventional drawbacks.

ットが前記取付ブラケットの下側に位置する部材を介し
て固定連結されている点にある。The characteristic structure of the working equipment mounting structure of the agricultural tractor according to the present invention, which was taken to achieve the above object, is that the mounting bracket for the lower link in the two-point link mechanism for mounting the working equipment is attached to the rear end of the machine around the front and rear axis. At the same time, fulcrum pins for a pair of left and right lower links in a three-point linkage mechanism for mounting a working device are mounted at the rear of the machine and at positions outside the left and right structures of the mounting bracket, respectively. The bracket is provided in a state that allows rotation of the mounting bracket, and the pair of fulcrum pin mounting brackets are fixedly connected via a member located below the mounting bracket.

の取付強度低下を防止したのである。However, if the mounting position of the fulcrum pin mounting bracket shifts back and forth or up and down, the posture and position of the work equipment relative to the machine will change significantly if the general standard specification three-point linkage machine a is installed as is. This will have a great negative effect on the lifting and lowering control and rolling control of the work equipment, making it extremely difficult or impossible to perform the intended work properly and reliably. Focusing on the fact that there is no difference in the work even if there is a slight deviation in the direction,
By increasing the distance between the left and right pair of fulcrum pin mounting brackets, even though they are installed together with both types of brackets, mutual interference between the two types of brackets and movement interference with the link mechanism by both types of brackets are eliminated, and it is fixed. By fixedly connecting the left and right fulcrum pin mounting brackets via the connecting member, it is possible to prevent a decrease in the mounting strength of both fulcrum pin mounting brackets due to an increase in the distance between the fulcrum pin mounting brackets.
