DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endless swivel belt having stems raised and raised at predetermined intervals so as to be able to swing up and down, and is arranged above and below a pair of case members connected to each other so as to face left and right. A pre-cutting process of a combine in which a vertically-rotating stem and stem pulling device constructed by being wound around a supported driving wheel and a driven wheel is arranged at an uncut moat end at a front end of a pre-cutting device. Regarding the structure.

[0002]

2. Description of the Related Art Conventionally, in this type of combine pre-treating structure, as disclosed in, for example, Japanese Utility Model Application Laid-open No. Sho 60-22112, a stem-and-stem in a vertically rotating stem and stem raising apparatus. At the lower part where the raising nail starts to be raised, the stem stem is raised in a state where it protrudes outward from the outer case composed of the pair of left and right case members. A cover member was provided on each case member so as to prevent stems and the like from being brought into contact with each other so as not to come into contact with the cut stem.

[0003]

However, in the above-mentioned conventional pre-cutting structure for combine harvesters, since the cover members are provided on both the case members, it is possible to remove straw chips that have been brought along with the stem and stems and raised claws. Mud and the like are likely to be caught and retained between the two cover members,
There is an annoyance that it is necessary to remove the staying straw waste and the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and it is possible to make it difficult for swarf debris or the like to stay in a cover of a standing position of a stalk-raising claw of a vertical rotating stalk-raising device. An object of the present invention is to provide a combine harvesting pre-processing structure.

[Means for Solving the Problems]

(Structure) In the pre-cutting structure for combine harvesting according to claim 1 of the present invention, the endless swivel belts, in which the stems are raised and the claws are pivoted at predetermined intervals so as to be able to swing up and down, are connected to each other in a right and left facing state. A vertical turning type stem and stem raising device configured by being wound around a driving wheel and a driven wheel respectively supported on the upper and lower sides of a pair of case members, and an uncut moat end at a front end of a cutting pretreatment device. The harvesting pre-processing structure of the combine arranged in the lower part of the vertical turning type stem and stem raising device, covering the movement trajectory associated with the standing of the stem and raising nails in the lower part of the vertical turning type stem and raising the nail, and turning the vertical turning to the support frame. A cover member for mounting the stem-pull raising device is provided only on the uncut side of the left and right case members of the vertical turning stem-raising device.

(Operation) According to the first aspect of the present invention, the cover member that covers the movement trajectory accompanying the erecting of the stem stem raising and nails from the side is formed of the uncut case of the left and right case members. Since it is provided only on the member, the straw debris, mud, and the like that have been entrained together with the stem stem raising claw will fall and move smoothly on the ground without being caught by the cover member.

(Effects) Therefore, according to the configuration of the first aspect of the present invention, in the state of being sandwiched in a narrow space, straw chips and mud are clogged or stay at the erected portion of the stem and stem. Can be eliminated, eliminating the troublesome work of removing the accumulated straw waste and the like.
Workability can be improved, and there is an advantage that the number of parts can be reduced because a single member is provided only on the uncut side of the case member instead of providing a pair of cover members.

According to a second aspect of the present invention, there is provided a combine pre-cutting structure according to the first aspect of the present invention, wherein the concave portion of the uncovered moat of the cover member is recessed into the machine body. And a support for supporting a tip of a weeding rod for weeding uncut stems and stems is provided in the recess.

According to the second aspect of the present invention, a concave portion is formed in the side surface of the uncut moat of the cover member so as to be recessed into the machine body, and the uncut moth stem is formed in the concave portion. Since the supporting member for supporting the tip of the weeding rod for weeding is installed, the supporting member of the weeding rod does not need to be separately provided on the support frame member or the like.

(Effects) Therefore, according to the configuration of the second aspect of the present invention, the parts can be shared.
In addition to being inexpensive, the cover can be mounted on the support frame in a state where the support is provided on the cover in advance, so that the workability of the assembling operation can be improved.
