Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a continuous transfer of a combine in which a mowing device and a handling depth adjusting device are vertically connected to the front part of the machine equipped with a threshing part and a traveling device. Regarding the device.

[Conventional technology]

Conventionally, the depth-of-handle adjusting device in the combine was designed to transfer the depth of cut to the feed chain of the threshing device after the depth-of-handle adjustment device that tilts the harvested culm to the center of the rear part is used. The guide rod was made to project obliquely outward from the lower surface of the middle part of the sandwiching carrier, whereby the root part of the grain culm was pushed outward and transferred to the beginning of the feed chain.

[Problems to be solved by the invention] Since the guide rod according to the conventional technology pushes out the stock base part with frictional resistance, the stock base part bends forward due to frictional resistance at the lower part of the stock base clamping carrier, As for the bend, the lower layer, which is in contact with the guide rod, is more serious than the upper layer, and the roots of the roots are uneven, and in this state, the roots are transferred to the feed chain, resulting in culm leakage, clogging, and unhandled parts.

In order to deal with this, it has been proposed to replace the guide culm with a conveyor chain without a sandwiching rail in this part, but at the end of the stock carrier sandwiching carrier, the start end portion of the transfer auxiliary rail and the feed chain are provided. From the above, especially in the case of a small amount of culm, culm slip and culm leakage were likely to occur, and it was not possible to improve the succession of the culm to the feed end of the feed chain where the culms have different postures.

[Purpose of device]

The purpose of the present invention is to provide the above-mentioned transferring section without causing unevenness in the root section and leakage of culm regardless of the amount of culm transported and how the handling depth adjusting device tilts. The present invention provides a transfer and transfer device equipped with an auxiliary stock source transfer device capable of accurately transferring a grain culm to a feed chain starting end portion.

[Means for solving problems]

A characteristic configuration of the present invention is that a threshing device mounted on a machine stand having a traveling device and a mowing device provided in front of the threshing device are provided with a handling depth adjusting device that tilts around the start end of the feed chain of the threshing device. In the combine harvester, which is provided with the stock basin part of the grain culm that has been adjusted in handling depth, is fed to the feed chain, and the ear part is supplied to the supply port, the auxiliary stock carrier is the stock source that constitutes the handling depth adjusting device. An auxiliary stock carrier is provided with the hypotenuse protruding outward from the lower part of the midway of the carrier to the vicinity of the start end of the feed chain, and the base end is attached to the machine frame facing the auxiliary stock carrier. From the good transport
An auxiliary rail having a terminal end portion extending toward the feed chain side is provided close to above the conveyance protrusion of the oblique side portion, and gradually advances as the conveyance lowers while approaching the base portion of the auxiliary rail. In the combine and transfer device in the combine, a guide piece hung so as to protrude downward is formed on the machine frame.

[Action]

In the above-mentioned combine, the grain culm cut and scratched by the reaper A is subjected to the depth adjustment by the depth adjusting device B, and then supplied to the threshing device 1 for threshing treatment.

Then, when the grain culm is post-fed by the handling depth adjusting device B, the stock-base sandwiching carrier 11 sandwiches and transports the stock-base portion, and is obliquely outward of the transport chain 16 of the auxiliary stock-source transport device C at a midway portion. By the gradually extending oblique side portion 16b, the stock base portion hanging from the stock base holding and conveying body 11 is gradually pushed outward and forcedly conveyed so as not to cause a transfer delay. Therefore, unlike the conventional guide rod that pushes out, the stock base portion does not bend forward due to resistance, and at the end of conveyance, as shown in FIG. 2,
The arc portion 16c following the hypotenuse portion 16b of the auxiliary stock carrier C is provided between the stock sandwiching carrier 11 and the start end of the feed chain 1a so as to enter and wrap the feed chain 1a. With the above-described action, the stock base is gently transformed rearward by the arcuate portion 16c, and is placed on the start end of the feed chain 1a in a posture substantially along the transport surface of the feed chain 1a. , The grain culls which are sequentially tilted in the lateral direction by the handling depth adjusting device are supported by the projection 16a and the transport chain 16 of the auxiliary stock carrier transporting device C from below the stock plant immediately before reaching the starting end of the feed chain. In the received state, the stock rail portion is pressed and clamped from above by the auxiliary rail 30 to cause no spillage and the like, and the feed chain 1a is regularly transported and conveyed to the starting end portion, and thereafter, is continuously transported on the feed chain 1a. Supplement Rails 26 and Setto order to pinch the soft strain base at joint action with the auxiliary lines based on the transport device C, to reliably engage conveyed to the feed chain 1a without causing culms spill a small amount of culms example.

At this time, when the grain culm is conveyed in a small amount, the auxiliary rail 30 that is thin and has a weak elastic force is in the state of FIGS. 3 and 4, and moves finely up and down according to the culm volume. Since the grain culm is properly sandwiched between 16 and conveyed, the end of the auxiliary rail 30 faces the feed chain 1a, and the handling depth adjusting device B
From the stock section to the feed chain 1a without fail
Transfer to.

Also, if a large number of grain culms are sent, an auxiliary rail
As shown in Figs. 5 and 6, 30 is largely displaced upward and sideward by being pushed by a grain culm, and the end of the auxiliary rail 30 tends to come off from the feed chain 1a starting end portion to the outside. In such a case, the inclined lower edge 36 of the guide piece 35 provided close to the base of the auxiliary rail 30 receives the stock base until the base of the auxiliary rail 30 is largely pressed. , This is gradually directed downwards and smoothly sent in cooperation with the chain 16. At this time, the continuous guide 37 prevents the winding at the end of the chain 16 and at the same time, supports and regulates the lowering of the stock origin. Therefore, since the end of the auxiliary rail 30 does not come off from the feed chain 1a so much, its elastic restoring force is easy to return to the original position, and it is always accurate regardless of the number of cut culms and there is no culm leakage. A good continuous transfer can be carried out in this part, and the end of the feed depth adjusting device B swings and the feed chain 1a.
Even if the continuous interval between and is displaced, good continuous transfer can be continued.
