Abstract

PURPOSE:To exactly lift up a spade, by a method wherein the spade is set to be lifted up, at the lower section of a fitted frame connected to a travelling machine unit, and wherein the upper section is provided with a lifting lever, and wherein the lifting lever is connected to the spade with a bendable connecting member. CONSTITUTION:When a spade 18 is retained in a form inclined forward and a travelling machine unit 1 is run, then the soil of a high cultivated field is excavated by the spade 18, and the excavated soil b is introduced into a conveying stand 12 via a soil introducing port 44. After that, when the soil b is conveyed up to a low cultivated field and retaining mechanism 17 is released, then the conveying stand 12 is inclined backward by tare weight, and the excavated soil b is discharged. When the spade 18 is lifted up, then by vibrating a lifting lever 23 and by engaging the lever 23 with an upper positioning groove 28, a connecting member 30 is bent, and the tip section of the spade 18 is vibrated upward with the center of a fulcrum pin 21.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a transport device for a tractor.

[Conventional technology]

Utility Model Publication No. 57-26937 has been known as this type of transporting device, and its configuration consists of three
The mounting frames are connected by a point-type support link mechanism, a transport platform is provided on the mounting frame, a plow is provided at the bottom of the mounting frame so that it can be moved, and a pull lever is provided on the top of the mounting frame to facilitate transportation. In this case, it is possible to pull up the bow by pulling up the bow 1-1.

[The problem that the invention attempts to solve]

However, in the case of the conventional structure, the connecting part +4 that connects the pull lever and the plow is formed of a rigid body that cannot be bent. Since interference is likely to occur, and the installation position of the pull-up lever must be located at a location where it is easy to operate while working and driving, the lower link 2 has been made into a bent shape to avoid interference, and as a result, the compatibility of the lower link has been improved. This also has the disadvantage that it becomes difficult to remove the mounting frame.

[Means for Solving the Problems] Since the present invention aims to solve these disadvantages, the gist thereof is to connect a mounting frame to a traveling aircraft by a three-point support link mechanism, A transport platform is provided on the mounting frame, a plow is provided at the bottom of the mounting frame so that it can be pulled up, a lifting lever is provided at the top of the mounting frame, and a connecting member that can bend the lifting lever and the plow. A tractor transport device is characterized in that it is configured by being connected to each other.

[Effect]

The lifting lever and the plow are connected by a bendable connecting member.

It is possible to tilt backwards around one center.

18 is a plow, a support plate 19 is fixed to the bottom of the plow 18, a bearing cylinder 20 is fixed to both left and right ends of the support plate 19,
The shaft 18 is installed between the left and right vertical portions 7b of the mounting frame 7 so as to be able to be pulled up and swung by the bearing cylinder 20 and the fulcrum pin 21, and the stopper plate 22 is installed between the vertical portions 7b of the mounting frame 7. 18 is held in a forward leaning position.

Reference numeral 23 is a pull-up lever, in which an upper connecting arm 24 is pivotally attached to the side surface of the vertical portion 7b of the mounting frame 7 by a pin 25, and a lifting lever is attached to the middle part of the upper connecting arm 24 by a pin 26. A positioning plate 27 is provided on the side surface of the vertical portion 7b, and one positioning plate 27 is formed with two positioning grooves 28 that can be engaged with the lifting lever 23.

29 is a lower connecting arm, and the lower connecting arm 29 is 1]
