In the conventional lifting device, (a) a substantially closed type lifting cover is installed to cover the endless rotating band with the lifting claw attached from the front and back sides; (For example, Japanese Unexamined Patent Publication No. 188012/1983) (b) A lifting cover that covers the front surface of the endless rotating band with a lifting claw attached thereto, and a cover for rotationally driving the endless rotating band equipped with the lifting claw. The rear cover member for supporting the drive pulley and the driven pulley and the rear cover member for supporting the guide member for erecting the lifting pawl are configured separately, and these rear cover members are connected with one frame member to construct the fuselage. Support the lifting device on the side. (For example, in 1987-
70738) is well known.

In the conventional configuration (a) above, since the lifting cover is of a closed type, when straw waste is drawn in as the lifting claw retires into the cover, it accumulates inside the cover and becomes a chain. In addition to being an obstacle to the operation, as shown in the above-mentioned publication (Fig. 2 of JP-A-60-188012), an elastic guide ( Publication figure number 31) is provided, and since this elastic guide and the lifting claw collide with each other, a collision sound is generated at that time. Moreover, this collision sound becomes louder as the triggering speed (rotational speed of the chain) becomes faster.
In addition, since the noise is expanded in the closed space of the lifting case, measures to muffle the noise were required.

かつた。 On the other hand, in the conventional structure (b) above, in order to solve the above-mentioned problem, the rear cover of the lifting device is provided with a part that is open to the outside, and the noise caused by the lifting claw is removed. This is designed to prevent straw debris from getting into the lifting device and make it unpleasant to the ears, and also to remove straw debris that has gotten into the lifting device. In order to support the rear cover, a frame member connecting the rear covers together was connected to the fuselage sides. For this reason, the frame member that connects them becomes large-scale and the number of parts increases, leading to higher costs.In addition, since the rear cover is partially located at the rear of the lifting device, This did not sufficiently eliminate the problem of straw debris and the like getting caught and accumulating.
本考案は、上記実情に鑑みてなされたものであ
つて、構造簡単でかつ騒音の発生やワラ屑の堆積

る。 The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a lifting device that has a simple structure and does not generate noise or accumulate straw waste.

The characteristic structure of the present invention is to connect the horizontal transmission case with the upper drive wheel of each lifting device to the upper part of the guide rail arranged along the lifting path to maintain the lifting pawl in the upright position. A back-open type lifting cover that covers the endless rotation band with the lifting claw attached from the front is integrally attached to the horizontal transmission case and the guide rail; The lower part and the weeding tool support rod are connected and supported, and their functions and effects are as follows.

By connecting the horizontal transmission case and the upper part of the guide rail to form a framework as a pulling device, the upper drive wheel and tension wheel body can be attached to these, which is different from the conventional structure. Since the lift cover is used to attach the wheels and guide rails, there is no need for the lift cover to be sealed and robust.

い。 Due to the characteristic configuration, the structure for attaching and supporting the pulling device to the side of the machine body is different from the structure in which it is connected and supported to the rear cover, and a connecting member is provided that can connect the lower part of the guide rail and the weeding tool support rod. Since only a small connecting member is required, a small connecting member can be used, and the rear cover of the lifting device can be completely eliminated, so there is no problem such as accumulation of straw waste etc. on the rear cover.
その結果、引起しカバーとしては裏面開放型の

As a result, the lifting cover can be of an open type on the back, so there is no accumulation of straw waste brought in, and even if there is a collision sound between the lifting claw and the elastic guide, the open type prevents the sound from being muffled. In addition, the structure for supporting the lifting device along the fuselage is simplified, and the number of parts and cost can be reduced.
