Description

[Detailed description of the invention] The present invention provides grass dividers in parallel in front of the center between a pair of left and right pulling devices and in front of the lateral outer parts of both pulling devices, and a grass divider is formed between these adjacent grass dividers. Of the stem culm introduction paths to both the pulling devices, the width of the stem culm introduction path located on the control section side is configured to be larger than the width of the other stem culm introduction path, and The present invention relates to a reaping harvester in which a vertically rotating forced raking device is provided at the rear of the grass divider located on both the left and right sides.

In this type of conventional reaping/harvesting machine, the left and right sides for transmitting power to the forced raking devices, respectively, are provided between the outer surfaces of the cases of the forced raking devices and the transmission cases to the two lifting devices. Since symmetrical transmission cases were provided, it was necessary to separately manufacture not only the cases of both forced scraping devices but also the left and right transmission cases with different shapes, which resulted in a change in mold type and number of processes. Due to this increase, the manufacturing cost becomes enormous, and in addition, the transmission case on the control section side is installed through the back of the forced raking device, so in order to make the amount of elevation of the reaping section sufficient, the above-mentioned method is necessary. The control section had to be installed on the lateral outer side of the forced raking device, which resulted in problems of narrowing the forward visibility and increasing the width of the machine.

In view of the above-mentioned circumstances, the purpose of the present invention is to reduce production costs, expand the forward visibility, and make the machine width more compact. Among the forced raking devices, between the inner surface of the case of the forced raking device located on the control section side and one end of the transmission case to the two lifting devices, and between the outer surface of the case of the other forced raking device and the transmission case. The present invention is characterized in that a transmission case having the same specifications is provided between the other end of the case and transmitting power to each of the forced raking devices.

That is, focusing on the fact that there is a sufficient space between the pulling device on the control section side and the forced scraping device adjacent thereto, the forced scraping device is inserted from the transmission case on the pulling device side through this space. By providing a transmission case for transmitting power to the left and right sides, it is possible to use not only the cases of both forced scraping devices but also the left and right transmission cases with the same specification, and the mold types associated with this can be used as the left and right transmission cases. Also, by reducing the number of steps, manufacturing costs can be significantly reduced. Moreover, since the transmission case on the control section side is not located at the back of the forced raking device as in the past, the control section can be inserted into the back of the forced raking device while ensuring a sufficient amount of elevation of the reaping section. In addition to expanding the forward visibility, we were able to make the width of the aircraft more compact.

Hereinafter, embodiments of the present invention will be described based on the drawings.
