JP 2000-23543 A (paragraphs [0014] and [0017], FIGS. 1, 2 and 6)

In the weeding device to which the above-described conventional technology is applied, the weeding defect and threshing are likely to occur depending on the stem pod.
In other words, in the weeding device to which the conventional technology is applied, the weeding rod performs the weeding motion that only swings back and forth around the horizontal axis of the aircraft. It is easy to obtain the herbicidal action due to, but it is difficult to obtain the herbicidal action by pushing the planted stalks upwards, and in the case of stalks that have significant entanglement such as rapeseed, the entanglement is difficult to be resolved. It was. In addition, the entanglement is not sufficiently solved and the push operation is performed, so that breakage and degranulation are likely to occur.

  An object of the present invention is to provide a weeding device of a harvesting and harvesting machine that can easily obtain a weed having a high accuracy of entanglement even in the case of a stalk like rapeseed.

The weeding device of a harvesting harvester according to the first invention is
It is equipped with a weed cocoon that has been set up in a vertical position so that weeds can act on the planting stems.
Fulcrum means for supporting the lower end side of the weed ridge so as to be rotatable and movable in the vertical direction of the aircraft,
There is a weeding rod connecting point that connects to the weeding rod at a position located on the upper end side of the weeding rod relative to a portion that is connected to the fulcrum means of the weeding rod. And a weed fence driving mechanism for driving the weed fence in a state of moving along a rotational trajectory in the vertical direction of the machine body.

  According to the configuration of the first aspect of the present invention, not only can the weed folds move toward the front of the aircraft to push the stems toward the front of the aircraft, but also the weed folds can move upward. It is possible to cause the herbicidal action to push the stalks upward and to effectively perform the herbicidal action, so that the effective herbicidal action can be exerted as a whole.

  Therefore, even in the case of stalks such as rapeseed, the entanglement is accurately resolved by the weeding action by pushing the aircraft forward and effectively pushing the aircraft upward, and the post-weeding process is performed well. It is easy to avoid tearing and degranulation due to the pushing operation with insufficient entanglement.

  The second aspect of the present invention is a state in which the weed ridge driving mechanism has a low moving speed in the forward direction of the machine at the connecting point of the weed moth, and a high moving speed in the rear of the machine of the connecting position of the weed moth. It is comprised so that the said weed tub may be driven.

  The weed cocoon moves toward the front of the aircraft and acts on the stalk. At this time, the weed pods move to the entry side with respect to the stem buds, and the stem pods tend to have a large resistance to movement against the weed pods. It becomes easy. The weed puppet moves toward the rear of the aircraft and returns to the position where the weed action starts. At this time, the weed pods move backward with respect to the stem pods, and the stem buds are less likely to have a large resistance to movement against the weed pods. Hard to occur.

  According to the configuration of the second aspect of the invention, the weed cocoon moves at a low speed toward the front of the aircraft and moves at a high speed toward the rear of the aircraft, thereby suppressing the occurrence of vibrations of the stem and starting the weeding operation. By returning to the position at high speed, it is possible to perform weeding with a weed culm while increasing the frequency with which the weed culm acts as a weed while the harvesting harvester moves a unit travel distance.

  Therefore, even in the case of stalks such as rapeseed, weeding with weed pods with good entanglement is possible while weeding buds are less likely to generate vibrations and weed pods act at a suitable frequency. Therefore, it is possible to facilitate the processing after weeding, and to suppress grain loss due to threshing.

  According to the third aspect of the present invention, the portion of the rotation locus corresponding to the forward movement of the connection portion of the weed bush is a straight line, and the weed bush in the rotation locus is a straight line. The portion of the connection point corresponding to the rearward movement of the aircraft is configured to drive the weed ridge in a state in which the curved line is a protruding curve upward of the aircraft.

According to the configuration of the third aspect of the invention, even if a driving force is input to the weed culm drive mechanism with a simple transmission structure, the weed culm acts as a weed while making it difficult for the stem buds to vibrate. In addition, the weed cocoon can be driven so that the weeding frequency of the weed moth is appropriate.
In other words, the part corresponding to the forward movement of the weed culm body in the weaving fence connection point of the weed moth driving mechanism is a straight line, and the weed moth body in the rotating locus of the weed moth connection point Since the weed fence is driven by the weed fence driving mechanism in a state where the part corresponding to the backward movement is a curved line protruding upward, the time for moving the weed fence to the front of the aircraft Even if you drive the weed fence with the same time to move the weed fence to the rear, you can slow down the forward speed of the weed fence and the rear The moving speed can be increased.
The weed cocoon moves toward the front of the aircraft and acts as a weed on the stalk. At this time, the weed moth moves to the entry side with respect to the stalk, and the stalk moth moves greatly with respect to the weed moth. Due to the resistance easily, when the weed cocoon moves at a high speed, a large vibration of the stem bud tends to occur. The weed cocoon moves backward and returns to the position where the weeding action starts.At this time, the weed cocoon moves backward with respect to the stalk, and the stalk moth has a large resistance to movement against the weed moth. Due to the fact that it does not easily occur, even if the weed cocoon moves at a high speed, large vibrations of the stem bud are unlikely to occur.

  According to the configuration of the third aspect of the invention, the weed cocoon can be moved at a low speed toward the front of the aircraft, and can be moved at a high speed toward the rear of the aircraft, thereby suppressing the occurrence of vibration of the stem and the appropriate It is possible to cause the weeding of the stem pods with the weed pods while making the weeds act on the shoots with the frequency of weeding.

  Therefore, even if a simple transmission means that inputs a driving force of constant speed rotation to the weed stalk drive mechanism is adopted, even in the case of a stalk like rapeseed, it is difficult to generate vibration of the stalk. Can be made to act on the stems at an appropriate frequency of herbicidal action, so that the entanglement can be satisfactorily loosened to facilitate post-weeding treatment, and grain loss due to shedding can be suppressed.

  In the fourth aspect of the invention, the upwardly facing surface of the weed ridge is a curved surface protruding upward.

  According to the configuration of the fourth aspect of the present invention, the weed cocoon can come into contact with the pedicle by the curved surface that protrudes upward, so that it can act as a weed while making it difficult to break or break the pedicle.

  Therefore, even in the case of stalks such as rapeseed, weeding treatment can be performed while suppressing the occurrence of loss due to breakage or breakage caused by contact of the stalks with the weed pods.

  In the fifth aspect of the present invention, the weed ridge is provided in a posture inclined with respect to the longitudinal direction of the aircraft so that the rear side of the aircraft is positioned on the laterally outer side of the aircraft.

  According to the configuration of the fifth aspect of the invention, as the stalk that has been entangled on the front end side of the weed cocoon moves to the rear end side of the weed pod along the weed shoot, Use the rear edge of the heel to push the machine laterally outward, and loosen it so that the stalks that have been loosened and separated on the front edge of the weed cocoon are separated to the stocker side at the rear edge of the weed moth. Can be done.

  Therefore, the weeding apparatus which can perform the excellent weeding from which the unwinding reaches to the strainer side can be obtained.

After that, the aircraft is supported in a vertical posture in a tilted state.

  The fulcrum means 33 is constituted by a support shaft 33a fixed to the lateral side portion of the weeding tool 62 and a roller 33b rotatably supported by the support shaft 33a. The roller 33b is movably engaged in a connecting long hole 35 provided by attaching a connecting plate 34 to the lower end portion of the weed basket 31. The connecting long hole 35 is arranged in a state of rising rearwardly located on the upper side of the traveling machine body toward the rear end side, and the fulcrum means 33 is rotatable on the lower end side of the weed fence 31 and in the vertical direction of the traveling machine body. It is supported to move freely.

  The weed ridge drive mechanism 40 includes the connecting link 41, a swing link 43 whose one end is connected to an intermediate portion of the connecting link 41 via a connecting pin 42, and a weed basket 31 of the connecting link 41.

The weed basket 31 is provided with a connecting portion 32 provided with a bracket attached to a part located on the upper end side of the weed stick relative to the part connected to the fulcrum means 33.
The connecting link 41 is connected to the connecting portion 32 of the weed pod 31 via a connecting pin 45 at one end side, and the connecting pin 41 is connected to a portion of the rotating body 44 that is deviated from the rotation axis 44a. Rotating body side rod 41b, one end side of which is connected via 46, and a connecting body 41c connecting the other end side of this rotating body side rod 41b and the other end side of weed rod side rod 41a. . The connecting body 41c is a member to which the swing link 43 is connected. The end portion of the swing link 43 opposite to the side connected to the connection link 41 is connected to a support portion 47 provided on the outer surface side of the lateral wall 61C of the pretreatment frame 61 via a connection pin 48. . The connection link 41 and the connection portion 32 of the weed ridge 31 are connected to each other around the traveling machine body lateral axis 45a included in the connection pin 45 in relative rotation. The connection link 41 and the swing link 43 are connected to each other around a traveling machine body lateral axis 42a included in the connection pin 42 so as to be relatively rotatable.

The driving force of the transverse feed auger 65 is transmitted through the wound transmission chain 52 and is driven at a constant speed.

FIG. 5 is a side view showing the weed basket 31 and the weed driving mechanism 40. A rotation trajectory T1 shown in FIG. 5 indicates a rotation trajectory of the traveling machine body lateral axis 45a serving as a weed rod connection point where the connecting link 41 is connected to the connecting portion 32 of the weed tube 31. A rotation locus T2 illustrated in FIG. 5 indicates a rotation locus of the upper end 31c of the weed pod 31.
As shown in FIGS. 4 and 5, the weed bush driving mechanism 40 constitutes a four-barrel rotating chain approximate linear interlocking mechanism, and drives the rotating body 44 with a driving force of constant speed rotation to The connecting link 41 is oscillated and driven by the rotating body 44 so that the traveling machine body horizontal axis 45a serving as the weeding rod connecting point draws the rotation trajectory T1, and the driving force of the connecting link 41 is transmitted to the weeding rod 31.

FIG. 7 is an explanatory view showing a rotation trajectory T1 of the machine body transverse axis 45a as a weed tackle connecting point of the weed tack driving mechanism 40. As shown in this figure and FIG. 5, the rotation trajectory T1 of the airframe lateral axis 45a has a portion Tf of the rotation trajectory T1 corresponding to the forward movement of the airframe lateral axis 45a that is a forward movement of the airframe. A portion Tr of the trajectory T1 corresponding to the backward movement of the machine body lateral axis 45a is a curved line projecting upward from the machine body.
Between the points DE on the rotation trajectory T1, the weed ridge 31 is moved forward at an angle of about 20 degrees. Between E-A, the weed ridge 31 is given an easy lifting function. Between A and B, the weed basket 31 is lifted up smoothly to exert the separating action. Between B-C, the weeding basket 31 is gradually moved in parallel. Slowly let go of weeding basket 31 between CD.

  As a result, the weed rod driving mechanism 40 moves the upper end 31c of the weed rod 31 in the longitudinal direction of the traveling vehicle and the vertical direction of the traveling vehicle by drawing the rotation trajectory T2 with the lower end side of the weed rod 31 as the fulcrum side. In addition, a portion of the rotation trajectory T2 corresponding to the forward movement of the weed rod upper end 31c is a straight line, and a portion of the rotation trajectory T2 corresponding to the backward movement of the weaving rod upper end 31c is corresponding to the movement. The weed culvert 31 is driven so as to have a curved line protruding upward from the traveling machine body.

  The distance that the machine body lateral axis 45a and the upper edge 31c of the weed ridges move backward in the traveling machine body is larger than the distance that moves in the forward direction of the running machine body, and the rotating body 44 is driven at a constant speed. Thus, the weed rod driving mechanism 40 has a low moving speed of the vehicle body lateral axis 45a and the weed rod upper end 31c in the forward direction of the traveling machine, and the vehicle body lateral shaft 45a and the weed basket upper end 31c in the backward direction of the traveling vehicle body. The weed basket 31 is driven in a state in which the moving speed of is high.

  Therefore, in the weeding device 30, when the weed pod 31 moves from the weeding action start position S (see FIG. 5) toward the front of the aircraft and acts on the planted stem pod, Since the planted stalk is likely to be a great resistance to movement against the weed stalk 31 after entering the planted stalk, weeding the weed shoot 31 so that it enters the planted stalk at a low speed. Driving at a low speed by the heel drive mechanism 40, the stalk 31 is made to act on the planted stalk while preventing the large vibration of the planted stalk, and the planted stalk is to be cut off. Weed the planted stems that are not to be cut.

  In the weeding device 30, when the weed pod 31 moves rearward and returns to the weeding action start position S, the weed shed 31 moves backward with respect to the pedicle and the planted shoot is separated. Since it is difficult to generate a large movement resistance with respect to the grass 31 and it is difficult to generate vibration of the planting stem, the weed 31 is returned to the weeding action start position S at a high speed. In the state where it is driven at high speed by the drive mechanism 40 and the frequency at which the weed pod 31 acts as weeds while the traveling vehicle 1 moves the unit travel distance is the frequency adapted to the planting stem pod such as rapeseed. 31 is applied to weed stalks.

  The weed bud 31 includes a tapered front end 31a, and the tapered shape of the front end 31a rushes into the intertwined planted stalk without causing the planted stalk 31 to be pushed down by the front end. I will do it.

  6 is a cross-sectional view taken along the line VI-VI in FIG. As shown in this figure, the weed ridge 31 is configured by a half-divided portion of a circular cylinder so as to have an aircraft upward surface 31b that is a curved surface protruding upward from the aircraft, The herbicidal action acts on the planted stalks while making it difficult for the stems to break or break due to contact with the planted stalks by 31b.

As shown in FIG. 2, the weed fence 31 is supported in a posture inclined with respect to the longitudinal direction of the traveling vehicle body so that the rear side of the traveling vehicle body is positioned on the lateral outer side of the traveling vehicle body.
As a result, as the planted stalks that have been entangled on the front end side of the weed pods 31 move along the weed pods 31 to the rear end side of the weed pods 31, The planted stalks that have been pressed by the rear end side of the grass 31 to the lateral outside of the machine body and loosened and separated on the front end side of the grass weed 31 are separated to the stocker side on the rear end side of the grass 31 You can let them relax.

  As shown in FIG. 1, the weeding device 30 includes a cover 71 that is stretched across a weed culm 31 and a support member 70 that extends from the pretreatment frame 61. The cover 71 is made of a flexible sheet material. The cover 71 is deformed into a curved state or returned to an extended state by the movement of the weed fold 31, while allowing the movement of the weed fold 31. The weed drive mechanism 40 is covered so as to prevent the stalks from entering the grass drive mechanism 40.

  The weed rod driving mechanism 40 includes an expansion / contraction adjusting portion 41d provided on the weed rod side rod 41a of the connecting link 41, an expansion / contraction adjusting portion 43a provided on the swing link 43, and a connecting position adjusting means 44b provided on the rotating body 44. I have.

  The expansion / contraction adjusting portions 41d and 43a of the weed rod side rod 41a and the swing link 43 are configured by using turnbuckle-type expansion / contraction screws. The connecting position adjusting means 44a of the rotating body 44 changes the position at which the connecting links 41 of the rotating body 44 are connected by using a plurality of connecting holes 44c arranged in the rotating body 44 in the radial direction. .

As shown in this figure, the weed ridge drive mechanism 40 has a rotation trajectory T1 at the point where the weed ridge 31 of the connecting link 41 is connected by changing the position where the connecting link 41 of the rotating body 44 is connected. Change to a different diameter. Then, the rotation trajectory T2 at the upper end of the weed basket 31 is changed in the same manner as the change of the rotation trajectory T1 of the connecting link 41.
