Description

[Detailed description of the invention] (Industrial application field) This invention threshes the harvested grain culm with the stock side protruding outside the machine, and transfers the threshed culm to the culm transfer device. The present invention relates to a culm cover that is pushed open on the culm side of the culm that is transferred by the culm transfer device in a combine harvester that is fed to a cutter and shredded.

(Prior art) A culm cover is provided on the outside of the culm transfer device in order to prevent workers' hands from entering, but this culm cover is designed so that it does not interfere with the transfer of the culm. It is necessary. For this reason, for example,
As described in Japanese Utility Model Publication No. 56-51717, Japanese Utility Model Application Publication No. 55-63636, Japanese Utility Model Publication No. 55-31861, etc., there is a structure in which a plant base cover is hung on the outside of the culm transfer device.

(Problems to be Solved by the Invention) In the above structure, when the culm is transferred by the culm transfer device, the culm cover is automatically opened so that there is no hindrance to the passage of the culm. However, in either structure, it is possible to open the plant head cover artificially, and there is a risk that the operator's hands or the like may be caught in the culm transfer device due to carelessness.

(Means for Solving the Problem) Therefore, in the present invention, a culm transfer device 3 that clamps and transfers the culm from the culm opening of the threshing device 1 to the cutter 2 is provided.
In the configuration in which the stock cover 4 is hung on the outside of the
Regulator 6 for restricting upward rotation of stock cover 4
and an exhaust culm sensing device 5 that detects the exhaust culm supply to the exhaust culm transfer device 3 are provided, and when the exhaust culm sensor 5 detects the exhaust culm supply, the regulating device 6 is interlocked so that the restriction is released. did.

(Operations and effects of the invention) The plant base cover 4 is restricted from rotating upward by the restrictor 6, and the worker cannot insert his/her hand or the like inside, but the culm transfer device 3 When the discharge culm sensor 5 detects that the culm has been supplied, the restriction device 6 becomes deregulated and the stock cover 4 becomes rotatable and opens appropriately when the discharge culm passes through, allowing the discharge culm to be cut without any trouble. Transferred to 2.

Therefore, even if an attempt is made to open the plant head cover artificially while the culm is not being transferred, it will not open due to the restricting action of the restrictor 6, thereby preventing accidents resulting in injury or death due to the operator's carelessness.

(Example) Next, an example of the present invention will be described with reference to the drawings. The threshing device 1 is mounted on a combine machine, and threshes grain while holding and transporting the base of the grain culm with a feed chain 7. A cutter 2 is attached to the rear side of this threshing device 1. In the drawing, the cutter 2 is attached to a pair of parallel rotating shafts 8 and 9 with a disc blade 10.
Although a so-called disk cutter is shown in which the culm, scraper 11, etc. are arranged at appropriate intervals, it is also possible to use a cylinder-type cutter that folds the culm body of the culm in half and cuts it with a rotating blade and a stationary receiving blade. good.

Between the terminal end of the feed chain 7 and the supply port of the cutter 2, there is a culm transfer device 3 that clamps and transfers the culm of the culm discharged from the culm discharge port of the threshing device 1.
is provided so as to face rearward in a plan view and tilt toward the tip side, and the feed chain 7 protrudes the stock side of the shed culm to the side of the machine body, and the threshed culm is transferred while moving toward the tip side. , the entire length of the culm is taken into the width of the machine body and fed to the cutter 2.

A cover 12 is provided to cover the upper side of this culm discharge device 3, and a cutter cover 13 is provided to cover the upper side and rear side of the cutter 2. A culm-shaped culm detection device 5 that acts on the culm being transferred by the culm removal device 3 and rotates upward is pivotally mounted 14 at the starting end position of the culm removal device 3 inside the cover 12. On the plant side corresponding to the culm device 3, a plant cover 4 is suspended by a hinge 17,
A rod-shaped regulating tool 6 for preventing the stocker cover 4 from rotating inward is pivotally mounted 15 on the inside of the cover 12 inside the stocker cover 4, and the ejected culm sensing tool 5 and this regulating tool 6 are connected by a connecting rod 16, and when the discharged culm sensing device 5 is rotated upward by the discharged culm, the regulating device 6 is also rotated upward and the stock base cover 4 can be rotated inward.
Reference numeral 18 denotes a rotation prevention piece that prevents the stock base cover 4 from opening outward. In addition, the tip of the stock cover 4 is
It is formed in an arc shape so that it can smoothly open inward by the culm.

The waste culm that is threshed by holding the stock end side in the feed chain 7 is detected by the waste culm sensing device 5, and the regulating device 6 linked to this waste culm sensing device 5 releases the rotation restriction of the stock end cover 4. As it is transferred to the cutter 2 by the culm removal device 3, the stock base cover 4 is rotated inwardly and upwardly to be taken into the width of the machine body, cut by the cutter 2, and discharged downward.

Claims (1)

[Scope of utility model registration request] A stock cover 4 is installed on the outside of the culm transfer device 3 that clamps and transfers the culm from the culm outlet of the threshing device 1 to the cutter 2.
In the structure in which the plant head cover 4 is suspended, a regulating device 6 that restricts the upward rotation of the stock base cover 4 and a culm sensing device 5 that detects the supply of culm to the culm transfer device 3 are provided in a related manner. This culm supply device for a threshing and culm cutter is characterized in that when the culm sensing device 5 detects the supply of the culm, the regulating device 6 is interlocked so that the regulation is released.
