Description

  The present invention is an improvement of the carrying tool, more specifically, it can be stably transported while maintaining a good support posture, and positioning adjustment at the support location of the nail blade portion can be omitted, The present invention relates to a rotary carrying tool for agricultural tractors that can reliably protect the nail blade.

As is well known, in order to cultivate fields and the like, a rotary is attached to the rear part of the tractor, and the rotary nail blade is pulled while rotating. By the way, when leaving this rotary, this rotary is very heavy and the claw blade is exposed downward, so it can not be placed in a normal carriage with good posture, It was very dangerous to fall out of balance.

  Therefore, conventionally, as a device for transporting such a rotary, a device in which a support is integrally attached to a cover of the rotary and can be transported in a suspended state using this support is disclosed (see Patent Document 1). . However, in the case of this support, since it is supported only by the mounting bracket, there is a risk that the load will concentrate on the mounting part and breakage, and as a result, the danger that the rotary will fall and the operator may be injured, There is a risk of damage to the rotary itself.

  Moreover, what attaches a part to the cover of a rotary and supports a nail | claw axis | shaft of a rotary is disclosed (refer patent document 2). However, in the case of this support tool, in order to support the nail shaft, the position of the nail shaft support base must be adjusted so that it does not interfere with the tilling nail, the work is troublesome, and the tilling nail is damaged by mistake in the support position. There is a risk of it.
