Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a harvested grain culm lifting device, and can be used as a harvested grain culm pulling device for combine harvesters, binders, and the like.

Conventional technology Conventionally, a lug guide was fixed to the lower case, a guide was fixed to the upper case, and driving sprockets were provided at both ends of both cases. This reaping grain culm lifting device had a structure in which a chain equipped with a lifting lug for raising the grain culm was built in and spanned over, and the two cases were connected with bolts or the like.

Problems to be Solved by the Invention The lower case to which the lug guide is fixed and the -1- side case to which the guide guide is fixed are joined with bolts, and a rotating pull-up lug is installed in both cases. When the lifting lug is installed between the predetermined positions, the lug guide and the guide guide raise the lifting lug, and at the same time, the lifting lug is held in a protruding state from both cases. In a guiding type reaped grain culm pulling device, when the grain culm is pulled up by the pulling lug, the grain culm may break and wrap around the chain. However, when the lug guide and guide guide raise and hold the lug, a large force is applied to the lug guide and guide. In order to prevent the joint from opening, it is necessary to increase the number of bolts used to connect both cases, and if a large number of bolts are used, the number of disassembly steps required to inspect and repair the chain will increase. needed a lot.

Means for Solving the Problems This invention forms a box by providing upper and lower U-shaped cases (2), (2) having an opening (1) on the negative side, and 2) has a removable structure, and the case (
2), (2) There is a rotating drive sprocket (
3), (3) are provided, and this drive sprocket (3), (
A chain (5) rotatably equipped with lifting lugs (4) for pulling up the grain culm is passed over the 3), and the chain (5) is attached to the lifting lugs (4) rotatably at appropriate intervals, and the chain (5) is attached to the lower and side surfaces of the lifting lugs (4). At the same time as the lifting lug (4) is erected, a U-shaped lug guide (6) is fixed to the bottom of the lower case (2) to an appropriate length to hold and guide it so that it protrudes from the opening (1). A reaped grain culm lifting device is constructed by detachably providing a guide guide (7) above the lug guide (6) for contacting and guiding the upper surface of the lifting lug (4).

Effect of the Invention For example, when a reaping grain culm lifting device is used in a combine harvester that raises grain culms to reap and thresh, cases (2) and (2)
) The lifting lug attached to the chain (5) built into the
4) stands up at a predetermined position by the lug guide (6) and the guide guide (7), and protrudes from the opening (1) of the cases (2), (2), and in this protruding state, the lifting lug (4) to the lug guide (6) and guide guide (
While the grain culm is being guided and held by the grain culm 7) and transported upward while being held and pulled up by the lifting lugs (4), the harvested grain culm is harvested by the cutting blade provided at the lower part, and the harvested grain culm is transported by the grain culm transfer device. The supplied grain culm is then transported through the threshing device and subjected to threshing processing.

Effects of the Invention According to the present invention, the guide guide (7) is removably provided on the upper side of the lug guide (6) that guides and holds the lifting lug (4) in the upright position at the same time as the lifting lug (4) is raised. 4) This lug guide (6) and guide guide (7)
