Description

[Detailed description of the invention] Industrial application field This invention relates to a threshing culm device such as a combine harvester.

BACKGROUND TECHNOLOGY Conventionally, a support leg of a holding rod provided along the lower side of a culm chain that clamps and discharges threshed culm is attached to the upper side of the support leg relative to the lower culm passage shelf. A structure in which rubber plates are attached to a mounting plate protruding at a predetermined length from the lower side of the clamping rod and fixed to the culm passage surface with bolts, rivets, etc. at predetermined intervals (for example, Utility Model Publication No. 57-67550). It was a threshing culm removal device (see official publication).

Problems to be Solved by the Invention For example, in a combine harvester, the harvested grain culm is held between the transfer chain and the transfer rod of the threshing device, and is threshed while being transferred through the threshing device, and the threshed grain is The grain is transferred and discharged from the threshing device to the grain lifting device,
The grain is fried by this grain frying device and discharged outside the machine. In addition, the threshed culm is supplied from the transfer chain and the transfer holder of the threshing device to the culm chain and the holder, and is transferred to the culm and the culm. In a combine harvester in which the waste culms are transported and supplied through the culm aisle shelf and into the waste culm processing equipment, where they are cut to a predetermined length and discharged onto the field surface, the upper part of the support leg of the holding rod is Rubber plates are fixed to the mounting plate protruding from the bottom of the clamping rod at predetermined intervals with bolts, rivets, etc. on the shelf surface of the culm passageway, so the rubber plates are attached to the entire length of the culm. In order to improve the elastic effect of this rubber plate, it is necessary to increase the total length in the vertical direction of this rubber plate installed in a hanging state. The position of the clamping rod has become higher, and the overall height of the threshing device of the combine has increased accordingly.

Means for Solving the Problem This invention consists of a clamping rod 2 installed along the lower side of the shedding culm chain 1 in order to clamp and discharge the threshed culm.
At the upper side position of the support leg 4 with respect to the lower culm passage shelf 3, the rubber plate 5 along the clamping rod 2 is moved so that the front and rear ends of the rubber plate 5 are projected below the clamping rod 2. It is fixed to the mounting plate 6 to be installed, and the middle part is engaged with the engagement plate 7 protruding from the lower side of the clamping rod 2 by using the elasticity of the rubber plate 5, so that it is attached to the culm passage shelf 3 surface. The structure is a hanging culm threshing device such as a combine harvester.

Effect of the invention The harvested grain culm is held between the transfer chain and the transfer rod of the threshing device, and is threshed while being transferred through the threshing device, and the threshed grains are fried in the hoisting device and machined. The threshed waste culm that is discharged outside is supplied from the transfer chain and the transfer rod of the threshing device to the removal culm chain 1 and the transfer rod 2, and is transferred to the removal culm chain 1 and the transfer rod. The waste culm is sandwiched between the culms 2 and 3, and is transferred and supplied into the waste culm processing device through the waste culm passage shelf 3, where it is cut into a predetermined length and discharged onto the field surface.

Effects of the invention With this invention, the culm chain 1 and the clamping rod 2, which clamp and transfer the exhaust culm, are connected to the culm passage in a state along the clamping rod 2 at the upper side of the support leg 4 of the clamping rod 2. The front and rear ends of the rubber plate 5 provided in a hanging state on the shelf 3 are fixed to the mounting plate 6 that protrudes below the clamping rod 2, and the middle part of the rubber plate 5 is fixed to the clamping rod 2. Since the lever 2 is engaged with the engagement plate 7 provided on the lower side of the rod 2, the elastic effect is improved because the rubber plate 5 is not fixed over its entire length, and the upper and lower parts of the rubber plate 5 are There is no need to increase the total length in the direction, so the total height of the threshing device of the combine does not increase, and since the elastic effect of the rubber plate 5 is good, the culm during clamping and transfer does not need to be supported. leg 4
Since the culm does not get caught, stable clamping and transfer of the culm can be carried out at all times.
