Description

[Detailed description of the invention] The present invention has a weeding tool that is placed on the side of the path for introducing the stem culm into the reaping device, and is swung from the position where it enters the path to the outside side of the path. The present invention relates to a reaping harvester that is provided so as to be driven to swing back and forth around its front end as a fulcrum over a range of positions.

This reaping/harvesting machine is capable of disentangling the stalk culms to be reaped and uncut stalks by swinging the weeding tool left and right, and also allows the weeding tool to disentangle the vehicle body when it enters the path. By providing resistance to the stem culms that move toward the end of the path as they advance, the stem culms whose movement is regulated by the weeding tool and the area where the weeding tool acts first are This device separates the stem culms that have passed through the front and back, making it possible to disentangle the stem culms to be reaped. There was a fear that I would not be able to fully understand the ties between my comrades.

The present invention has been developed in view of the above-mentioned circumstances, and its purpose is to make a simple modification to the drive and vibration structure of the weeding tool to sufficiently unravel the entanglement between the stalks and culms of the cutting device. The point is to make it possible.

The characteristic configuration of the present invention is that the above-mentioned reaping/harvesting machine is provided with a support portion that supports the front end of the weeding tool so as to be able to swing from side to side and back and forth, and to swing the weeding tool toward the inside of the path. The point is that a mechanism is provided that swings and drives the camera to move it forward as the camera moves forward.

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

In other words, by moving the weeding tool forward as it swings toward the inside of the path, the weeding tool that has entered the path only provides resistance to the movement of the stem culm toward the end of the path. Instead, the stem culm can be pushed toward the starting end of the path, so
By keeping the stem culm on which the weeding tool pushes and the stem culm that has passed through the weeding tool's action point a large distance back and forth, it is possible to sufficiently untangle the stalk culms to be reaped. As a result, a reaping and harvesting machine that can be used more effectively by suppressing problems such as transportation troubles caused by entanglement of stems and culms has been obtained.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, a pair of left and right propulsion wheels 1, 1 and a grounding sled body 2 located in front of the wheels 1 are provided, respectively, so that the vehicle can move forward. A clipper-type cutting blade 4 is provided on the terminal end side of the stem culm introduction path A, which is equipped with a pair of rotating spiral bodies 3, 3 for pulling up the stem culm, so that the stem culms such as planted straw can be cut off as the machine advances. configure,
A pair of left and right stump clamps are provided which extend the left and right helical bodies 3, 3 rearward beyond the point directly above the cutting blade 4, and pinch and convey the stump base of the reaped stem culm toward the rear and upper side of the vehicle body. The conveyor belts 5, 5 are provided with the conveyance start end facing the end of the path A, and the reaped stem culm is lifted upward and conveyed while changing its posture to a laid-down position in which the tip side is located toward the front of the vehicle body. A pair of upper and lower clamping and conveying belts 6, 6 that pinch and convey the middle part of the stem in the culm direction in the collapsed position toward the right side of the vehicle body, and a conveying stem located near the belts 6, 6. A belt 7 with a locking protrusion that locks and conveys the culm toward the right side of the vehicle body, and a conveyor with a protrusion that locks and conveys the culm toward the right side of the vehicle body while combing the tips of the culms toward the tip side. In addition to providing belts 8, a wide belt 9 with protrusions that acts on the base of the conveyed stem culms so as to pull out the short ones that are not pinched backwards from among the conveyed stem culms is provided to perform stem culm sorting. A gutter-like collection tool 10 is provided to receive and collect the stem culms that are conveyed after being sorted as described above, and the work of reaping and sorting the stem culms as they progress is automatically carried out. This is a walking type reaping machine that continuously performs cutting.

However, the reaping and harvesting machine with the above configuration mainly performs reaping work with the uncut stem culms located on the left side of the vehicle body, and as mentioned above, the stem culms discharged rearward are placed on the right side of the vehicle body. A chute 11 is provided to receive and guide the discharged stem culm toward the uncut stem culm to prevent the discharged stem culm from falling onto the uncut stem culm.

As shown in FIGS. 3 and 4, a rod-like weeding tool 12 is placed on the left lateral side of the stem culm introduction path A, overlapping the starting end of the spiral body 3 and at the starting end of the spiral body 3. It is provided in such a way that it protrudes further forward. A pair of rollers 13, 13 are provided that engage and support the front end of the weeding tool 12 so as to be able to swing left and right as well as move back and forth. The weeding tool operating swing lever 14 to be connected is pivoted from side to side about the front side of the weeding tool pivot connection part as a fulcrum so as to move forward as it swings inward to the path A. The crank arm 16 is interlocked and interlocked with the bevel gear mechanism 15 which is pivotally connected and further transmits the power from the upper lateral conveyance holding conveyor belt 6 to the left rotary spiral body 3 so that the crank arm 16 rotates integrally with the bevel gear mechanism 15. A push/pull rod 17 is provided which interlocks and connects the weeding tool 16 and the swinging lever 14 to a position where the weeding tool 12 enters the path A and a position where the weeding tool 12 is swung to the outside side of the path. It is configured to be driven to swing back and forth around the front end as a fulcrum, and to be driven to swing forward as it swings toward the inside of path A.

In short, the relationship between the uncut stem culm and the stem culm to be harvested,
Also, it is possible to effectively disentangle the entanglements between the stalks and culms to be harvested.

The present invention can also be applied to reaping and harvesting machines that are not equipped with a culm pulling device. The support part that supports the front end of the weeding tool 12 so as to be able to swing left and right as well as move back and forth is provided with guide rollers 13, 13, and is composed of a vertical pin and a long hole along the front and back direction. Various structures can be applied, and in addition to using the swing lever 14 to configure the swing drive mechanism, various structures can be applied.
