Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for removing straw from a threshing machine, which is equipped with a binding device equipped with a packer for pulling the waste straw bundle into the binding space at the conveyance end of the waste straw bundle holding and conveying device. The present invention relates to a binding processing device.

This type of conventional waste straw bundling processing device is configured to directly feed the waste straw bundle sent out from the clamping and conveying device into the raking action range of the packer. , a state in which not all of the waste straw bundle is discharged from the clamping and conveying device, that is, only the portion of the discharged straw bundle on the lower side of the conveyance, which tends to be pushed and spread in the conveying direction by the clamping and conveying device, is discharged from the clamping and conveying device. In such a situation, there is a risk that the packer will scrape into the waste straw bundles, and the posture of the waste straw bundles will be disturbed as a result, leading to troubles in which the bundled waste straw cannot be fed to the binding device in a predetermined position. There was an inconvenience that led to troubles that resulted in mistakes.

The present invention aims at overcoming the above-mentioned drawbacks.

The characteristic structure of the waste straw bundling processing device of the present invention, which has been made to achieve such an object, is that in conjunction with the vertical movement of the end of the clamping rail of the clamping and conveying device,
During upward movement, the bundle of waste straw sent out from the clamping and conveying device is received and held at a position outside the raking action range of the packer, and during downward movement, the receiving and holding is released and the bundle of waste straw is transferred to the packer. The point is that a mechanism is provided to supply the material within the raking action range.

Next, the effects of the characteristic configuration of the present invention will be described.

In other words, the waste straw bundle discharged first from the clamping and conveying device is once received and held, and as the next waste straw bundle is conveyed to the terminal end of the clamping and conveying device, the previously received and held waste straw bundle is held. By supplying the bundle to the packer, the bundle of waste straw that is not clamped by the clamping and conveying device is scraped in by the packer, and the bundling process can be performed well as specified.

Moreover, by utilizing the vertical movement of the terminal end of the clamping rail as the waste straw bundle passes, the mechanism is configured to switch between the receiving holding state and the receiving releasing state. As in the case of an independent configuration, a sensor for detecting the conveyed and discharged straw bundle and a drive for automatically and reversibly operating the mechanism from the receiving and holding state to the receiving and releasing state based on the detection result of this sensor. There is no need to provide a mechanism, and the above-mentioned effects can be achieved economically while simplifying the structure.

Embodiments of the present invention will be described below based on the drawings.

To configure a harvester, which is an example of a threshing machine,
A threshing device 4 is mounted on a body frame 2 having a pair of left and right crawler traveling devices 1, 1, with its threshing peg carrying device (an example of a straw removing straw holding and carrying device) 3 extending along the left and right lateral directions. A grain culm supply stand 5 is installed on the grain culm supply port side of the threshing device 4, which can be changed between a substantially horizontal grain culm feeding posture and a stored posture, and a grain culm feeding table 5, which can be changed between a substantially horizontal grain culm feeding posture and a storage posture, is installed on the grain culm supplying port side of the threshing device 4, and a grain culm feeding table 5 is installed on the grain culm feeding port side of the threshing device 4, and the grain culm feeding table 5 is installed on the grain culm supplying stand 5 that can be changed between a substantially horizontal grain culm feeding posture and a storage posture. A binding device 6 is provided which collects and binds a plurality of bundles of waste straw sent out from the device 3 in a horizontal orientation, and then releases the bundles.

To configure the binding device 6, a packer 8 for scraping the waste straw bundles into the binding space 7 and a needle 9 for supplying binding cords are provided in the lower part of the binding space 7, and a needle 9 for supplying binding strings is provided in the upper part of the binding space 7. is provided with a string holder 10, a string knotting building 11, and a discharge arm 12 for discharging a large bundle of bundled waste straw.

To configure the thresher holding and conveying device 3, sprockets 15 for hanging the threshing field chain 14 are provided at both ends of a conveying frame 13 constructed along the upper part of the handling opening of the threshing device 4, and Guide pins 18 of a plurality of mutually pivotally connected clamping rails 17 are displaceably displaceable in the far and near directions relative to the lower clamping and conveying surface of the threshing field chain 14. In addition to being inserted and supported, the clamping rail 1
A spring 19 . . . which urges the grains 7 .

Therefore, between the member 21 fitted on the stock side of the rotating shaft 20 of the conveyance end sprocket 15 and the bracket 23 fixed to the safety cover 22 of the threshing field chain 14, and the rotating shaft The receiving rods 24, 24, which are located above the scraping locus of the packer 8, are connected between the member 21 fitted on the tip side of the threshing device 20 and the bracket 23 fixed to the threshing device 4, respectively. The discarded straw bundle that has passed through the clamping rail 17 is attached to the clamping rail 17, which is located at the end of the conveyance, and receives the fixed receiving rod. A fulcrum member 26 has a movable holding rod 25 that can be received and held between the rails 24 and 24 and is pivotably pivoted up and down, and the other end of the movable holding rod 25 is connected to the rail base 16. is locked and held through a pin 27 and a long hole 28, and in conjunction with the vertical movement of the clamping rail 17, the waste straw bundle sent out from the clamping and conveying device 3 is transferred to the packer 8 during upward movement. It constitutes a mechanism 29 that receives and holds the waste straw bundle at a position outside the raking action range, releases the receiving hold when moving downward, and supplies the waste straw bundle to the raking action range of the packer 8.

The transport frame 13 is provided with a presser rod 30 that restricts the upward movement of the bundle of waste straw scraped by the packer 8 and guides the bundle into the bundling space 7.
The movable holding rod 25 is installed in a state that allows the bundle of waste straw to be received and held, that is, in a state that allows the movable holding rod 25 to escape upwardly against the elastic biasing force.

FIG. 4 shows another embodiment of the mechanism 29, in which a movable holding rod 25 pivotally mounted to the clamping rail 17 and a member 31 pivotally mounted to the fulcrum member 26 are arranged in an X-shape. They are linked via a pair of links 32, 32.

FIG. 5 shows another embodiment of the mechanism 29, in which the movable holding rod 25 is connected between the movable holding rod 25 pivotally connected to the clamping rail 17 and the rail base 16.
A spring 33 urges the movable holding rod 25 to a receiving and holding position for receiving straw, and as the clamping rail 17 moves downward, the movable holding rod 25 is moved to a receiving and releasing position against the elastic biasing force of the spring 33. A cam 34 and a cam follower 35 are provided for switching operation.

FIG. 6 shows another embodiment of the mechanism 29, which includes a fulcrum member 26 fixed to the rail base 16.
A first link 36 that swings in conjunction with the vertical movement of the clamping rail 17 and a second link 37 pivotally connected to the rear end of the first link 36 are pivotally connected to the clamping rail 17. The movable holding rod 25 pivotally connected to the second link 37 is connected to the third link 3.
It is linked via 8.
