DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stem and culm harvester for rushes and the like, in which stalks and stalks are entangled with a weeding rod mounted in an upwardly inclined manner.

[0002]

2. Description of the Related Art There is a weed harvester in which a round bar is flattened and rotated about its central axis (Japanese Patent Publication No. 06-061177). During this rotation, the upper part of the peripheral surface of the weeding rod reciprocates up and down in the radial direction due to the flattening described above, and this displacement is transmitted to the planted rush and the entanglement between the rush grass rows is released. Will be.

[0003]

In the above-mentioned conventional weaving process using a weeding rod, the upper part of the peripheral surface of the weeding rod, which covers almost the entire length, is similarly displaced up and down.
When the tip of the weeding rod begins to contact the lower part of the rush that lays and entangles, the rush is rapidly displaced up and down, and is forcibly disentangled and processed. As a result, large friction occurs between the rush and the weeding rod, and the friction force makes the rush more susceptible to damage.

An object of the present invention is to provide a culm harvester for rush and the like, which has reduced friction with a weeding rod under such circumstances to prevent damage to rush and the like.

[0005]

In order to achieve the above object, the present invention provides a stem / culm harvesting machine in which a weeding rod mounted on a rearward upward slope disentangles between stem / culm rows. The front end of the weeding rod is reciprocally displaceable in the longitudinal direction, and is supported so as to be able to swing up and down around a horizontal support shaft. The rear end of the weeding rod has a constant radius of rotation around a horizontal rotation shaft rotated at a specific position. To rotate.

According to the present invention, the tip of the weeding rod does not move vertically in the upper part of the peripheral surface, but the vertical displacement increases toward the rear end. Therefore, the weeding rod does not give a large weeding action to the lower part of the rush etc. at the tip, but gives a greater weeding action toward the rear, and does not damage the rush etc.

The above-described invention is specifically as follows. That is, a vertical weeding catching and conveying device provided with a vertical tine that is moved in parallel in the rear upward ascending direction is provided continuously to the rear end of the weeding rod. In this way, the stem culm, in which the vertical tine is not understood only by the weeding rod, is surely unraveled and processed to its tip.

[0008] In addition, a rotational power is transmitted from the input drive shaft mounted on the upper part of the raising device to the horizontal rotary shaft via an endless chain arranged in a vertical tine. In this case, an endless chain originally necessary for arranging the vertical tines also functions as a transmission means of the weeding rod, thereby simplifying the structure.

[0009]

The operation of the mowing unit 4 configured as described above will be described. During the movement of the machine body by the operation of the crawler traveling device 1, the weeding device 8 releases the entanglement between the rows of planted rush w.
The raising portions 9a and 9b of the raising device 9 sequentially raise the three planted rushes w by the ascending movement of the tines t. The cutting device 11 cuts the roots of the planted rush grass w, and the cutting device 11 cuts the stem of the planted rush grass w. It is to be transported by hanging.

In the process of suspending and transporting, the upper and lower laterally engaging transporting devices 12a and 12b clip and transport the root portion of the rush grass w to the right side, and subsequently the rooting and transporting selecting device 15 for harvesting. The selection action is given while the stock root side portion of the rush w is conveyed to the right side, and the aircraft is gradually turned sideways to the right.

The stock-side portion having reached the predetermined height in the sideways posture as described above is lifted on the upper surface of the transport deck 14 by a transport device (not shown) and supplied to the locking claw selecting device 16. The locking claw selecting device 16 sets the locking claw for selection to a w
It penetrates into the group and moves in the length direction of the culm, and scrapes trash that is not held by the stem tip holding / conveying device 10 to its stock side. During the selection process, the locking claw selection device 16
Is supplied with a subsequent group of rushes, and the stock side of the rushed w groups that have been selected is pushed backward. On the other hand, the debris pulled out by the locking claw selection device 16 is drawn out by an unillustrated discharge device and falls to the ground.

The rushes w on the transport deck 14 which have been thus selectively discharged are sent to the binding device 17 by a backward transport device (not shown). The bundling device 17 includes
At step 0c, a group of rushes w supporting the tip of the stem is bound, and after the binding, kicking out the bundle w1 to the bundle holding region R1 with the release arm is repeated at a constant timing.

Next, the loading processing configuration for loading the rush bundle w1 sent from the cutting unit 4 will be described as follows. That is, as shown in FIG. 1 and FIG. 2, the rush bundle stacking device 18 provided with a vertical transport portion 18a provided at a position near the front of the machine base 2 and a horizontal transport portion 18b protruding rearward from the upper portion thereof. Is provided.

The vertical transport section 18a has its main body standing upright on the machine base 2, extending drive chains vertically on the left and right sides, and supporting rods 19 between these drive chains. The bundle receiving member 20 is fixed at an appropriate interval position, and moves up and down at an appropriate timing.

The horizontal transport section 18b stretches a transport belt 21 in the front-rear direction via a guide wheel.
The rush bundle w1 is conveyed rearward from the front end 21a and dropped from the rear end 21b by the traveling movement of, and the position of the rear end 21b is moved rearward or forward by the expansion and contraction operation of the horizontal cross-type telescopic link device 22. The length of the horizontal transport portion of the transport belt 21 is changed continuously. A cart 23 is fixed to the loading table 6 so as to be operable to unload.

To explain the operation of the above-described loading processing structure, the loading table 6 is in a state of being raised to the highest position at the start of harvesting when the vertical crossing type lifting / lowering link device 5 is operated to extend, and on the other hand, in the vertical transport section. The bundle receiving member 20a stands by at the imaginary line position k, and the horizontal transport portion 18b is in a state where, for example, the rear end 21b has reached the rearmost position.

In this state, when the rush bundle w1 is released from the cutting unit 4 to the bundle holding region R1, the vertical transport unit 18a is operated in connection with this, and the bundle receiving unit 20 moves the bundle holding region R1. The rush bundle w1 is scooped up, transported upward as it is, and transported to the front end 21a of the horizontal transport section 18b. After such transport, the bundle receiving section 20 is returned to the position of the virtual line k and stands by.

In connection with the operation of the vertical transport section 18a, the horizontal transport section 18b is operated, and the front end 21a of the transport belt 21 is moved.

a.

When such an operation is performed a certain number of times for each rush bundle w1 discharged from the cutting unit 4, the rush bundle w1 is stacked in a single layer over the entire front and rear length range on the loading platform 23a. As a result, the loading table 6 is lowered by the height of one layer of the rush bundle w1, and thereafter the rush bundle w1 is loaded on the second layer according to the above. As a result, the rush bundle w1 is stacked on the loading platform 23a in an orderly manner without being damaged by falling.

Next, the structure of the control unit 7 will be described.
A control stand 24 is erected at the forefront, and a control seat 25 is provided behind the control stand 24. A sunshade cover 26 is provided above the control stand 25, so that the pilot can sit and control the vehicle.

Reference numeral 27 denotes a prime mover provided below the cockpit 25 for supplying power to each operating portion.

The overall configuration of the rush harvester according to the present invention is as described above. Next, the main configuration of the rush harvester, that is, the configuration of the weeder 8 will be described in detail.

That is, as shown in FIG.
a, 8b, 8c, and these weeds 8a, 8b,
8c are arranged one by one between each row of rushes. Each weeding section 8a, 8b, 8c is provided with a weeding plate 28 at the forefront, followed by a weeding rod 29 and a vertical weeding locking and conveying device 30 in this order.

The above components will be described.
Is fixed to the frame 4b of the mowing part 4, as shown in FIG. 1, and its working surface 28a is inclined rearward upward.

The weeding rod 29 is a rod having a cross section such as a circle or an ellipse, and is provided so as to be inclined upward and backward. As shown in FIGS. 3 and 4, the support structure of the front end portion 29a of the weeding rod 29 has two support plates 31, 31 at the end of the frame 4b, and a horizontal support shaft 32 is fixed thereto. On the other hand, a long hole n is provided in the front end portion 29a, and the long hole n is externally fitted to the lateral support shaft 32. Further, a U-shaped portion 29b is formed in the rear end portion of the weeding rod 29. The left and right portions of the U-shaped portion 29b are connected to the crank formed by fixing the arm 34 to the left and right ends of the horizontal rotation shaft 33 provided at a constant height.

The vertical weed retaining and conveying device 30 is mounted in a rearwardly upwardly inclined manner in the front-rear direction via the raising portion 9b or the cutting portion frame.
As shown in FIG. 4, a sprocket 35 having the horizontal rotation shaft 33 as a center of rotation is provided at a lower end of the sprocket, and a sprocket 37 interlockingly connected to an input drive shaft 36 mounted on an upper portion of the raising device 9 is provided at an upper end. Provided, these sprockets 3
5 and 37, an endless chain 38 is wrapped around the chain 38, and a number of vertical tines 39 are arranged on the chain 38 so as to be able to be turned upside down. The tines 39 are located at the front edge and the upper edge of the main body case 30a. It is configured to stand when it is done.

The operation of the main part constructed as described above will be described. The rotation of the input drive shaft 36 is controlled by the rotation of the sprocket 37,
And transmitted to the horizontal rotation shaft 33. At this time, chain 3
The upper portion 8 moves upward from below. The rotation of the horizontal rotation shaft 33 causes the U-shaped portion 29b of the weeding rod 29 to rotate around the horizontal rotation shaft 33 via the arm 34, and the rotation of the U-shaped portion 29b causes the distal end 2 of the weeding rod 29 to rotate.
9a is reciprocally slid in the direction of the weeding rod 29 via the lateral support shaft 32 and the elongated hole n.

On the other hand, each weeding section 8a, 8b,
8c penetrates between the rows of rush grass w, first the weeding plate 28 squeezes between the right and left rows of stock, and then the weeding rod 29 contacts the planted rush grass w of the left and right rows at progressively higher positions. It will unravel the entanglement.

In this unraveling process, the tip portion 29a of the weeding rod 29 comes into contact with the lower part of the rush w to apply weeding force, but the tip portion 29a is slid only with little vertical displacement. Therefore, the herbicidal action at this time is weak, and does not give the rush w its rapid weeding power. Then, as the aircraft advances, the weeding rod 29 comes into contact with the rush w at a gradually higher position in relation to its inclination, and the vertical displacement gradually increases, so that the weeding action gradually increases, and the rush w When the rear end of the grass rod 29 is reached, it is unraveled to the tip of the stem and is separated in each row.

Such a series of unraveling treatments does not give an excessive unraveling action to the whole rush w.
Since 9 is not rotated around its central axis, the rush w is not involved and the rush w is hardly damaged.

When the airframe further advances, the vertical tine 39 acts to scrape the stem of the rush w which the weeding rod 29 has broken, and tries to hold the rush w in the upright posture. As a result, the rush w is smoothly caused and taken over by the device 9, and is reliably and efficiently caused.

Next, a modified example of the rush harvester according to the present invention will be described. As shown in FIG. 5, two weeds 8a and 8b are provided. At this time, the weeding sections 8a and 8b are arranged one by one between the left strip of the first row a and the right strip adjacent to the first row in the three rows that are simultaneously cut.

A simple weeding rod 40 is fixed at a position between the second and third items b and c. The weeding rod 40 is provided as needed, and may be omitted.

Two raising portions 9a and 9b are provided in the same manner as in the previous embodiment, but the tine t of the right raising portion 9a is not long, and the tine t of the left raising portion 9b is not short. These tines t are configured to oppose close to each other just behind the weeding section 8b on the left side. Other configurations are the same as in the previous embodiment.

The harvester as described above can be used not only for three-row cutting but also for two-row cutting, and is suitable for multiple-row cutting of narrow rows of rush grass w between rows.

[0043]

According to the present invention described above, the weeding rod gradually imparts a strong weeding power from the lower part of the stem to the stem tip of the planted rush, and the weeding rod moves around its central axis. Since it does not rotate, it does not involve the stem and culm, so that damage to the stem and culm during weeding can be effectively prevented.

According to the second aspect of the present invention, the vertical tine of the vertical weed holding and transporting device lifts the stem tip of the planting rush or the like in which the weeding rod has been broken, so that it can be transferred to the raising device. It becomes smooth and the raising device can be raised reliably and efficiently.

According to the third aspect of the present invention, the weeding rod can be driven via a chain which is originally required for driving the vertical tine of the vertical weeding locking and conveying device. Is simplified and the structure is simplified.
