[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sugar cane harvester.

[0002]

2. Description of the Related Art Sugar cane harvest is associated with the running of a car body.
While cutting the sugar cane with the cutting device on the front end of the car body,
The cut sugar cane is conveyed in the front-back direction by the conveying device in the vehicle body toward the rear while being cut into pieces by the cutting device in the middle of the conveying device.

The shredded sugar cane is received from a conveyor on an ascending conveyor, and is thrown from the conveyor into a bag or box mounted at the rear end of the vehicle body for harvesting.

In such a type of sugar cane harvester, as shown in FIG. 4, a pair of left and right spiral cylinders 2 standing up diagonally rearward are provided on both sides of the front end of the vehicle body 1,
The pair of left and right spiral cylinders 2 causes the sugar cane to fall and cuts at a portion near the root of the stem.

Further, as shown in FIG. 5, scooping plates 3 for scooping up sugar cane lying on the field are provided on both sides of the front end of the vehicle body 1. The scooping plate 3 has a shape close to a triangle, and the tip of the lower side runs under the ground to scoop up sugar cane that has fallen into the field by the upper side that slopes backward from the tip and slopes backward. There is.

The scooping plate 3 is fixed to the vehicle body 1 by means such as welding.

[0007]

According to the sugar cane harvester as described above, since the spiral strip of the spiral cylinder is continuously provided over the entire length from the lower end to the upper end of the outer peripheral surface of the rotary cylinder, it is caused by the spiral cylinder. The tip of the sugar cane protruding upward from the upper end of the spiral cylinder.

Then, the protruding tip portion is caught by the driving motor of the spiral cylinder, the support arm of the spiral cylinder and other portions, and the sugar cane is drawn into the vehicle body in the caught state, which prevents the sugar cane from being drawn in. To be done. That is, it is not drawn in smoothly.

For this reason, the sugar cane harvester is backed to remove the catch, or the running operation of the sugar cane harvester is stopped, and the sugar cane is manually detached and separated using a cutting tool such as a rotary hook. This causes a troublesome inconvenience of having to remove the entangled material. Due to the above-mentioned inconvenience, the operation rate of the sugar cane harvester is also lowered, and it may cause a failure.

Further, as described above, if the scooping board is fixed to the vehicle body, the scooping board is attached to the root stones or sprinklers of the field at the time of sugar cane harvesting, or the gutters when the direction of the sugar beet harvester is changed. When a collision occurs, a strong impact force is applied to the scooping plate, which damages the scooping plate and damages the mounting portion and the vehicle body side.

Therefore, an object of the present invention is to provide a sugar cane harvesting machine which eliminates the catching of the tip of the sugar cane caused and the damage to the car body caused by the collision of the scooping plate for scooping the sugar cane. To do.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is to mow by a reaping device on the front end side of the traveling vehicle body while causing sugar cane by rotating spiral cylinders on both sides of the front end of the traveling vehicle body. While the cut sugar cane is being conveyed by the first conveying device in the vehicle body, it is shredded by a cutting device in the middle of the first conveying device, and the shredded sugar cane is received by the second conveying device in the rear end of the vehicle body. In the sugar cane harvesting in which the shredded sugar cane of the second transfer device is put into a harvesting bag or box that is detachably engaged with the rear end undulating rotary arm of the vehicle body by an appropriate means, the spiral cylinder is used. Is a sugar-raised spiral strip from the lower end to the middle of the upper part,
The spiral spiral is formed from the upper end toward the upper end of the spiral spiral, and the spiral spiral is a reverse winding spiral.

Further, while the sugar spiral is generated by the rotary spiral cylinders on both sides of the front end of the traveling vehicle body, the reaping device on the front end side of the traveling vehicle body cuts the sugar cane, and the cut sugar cane is cut in the middle of the first conveying device in the vehicle body. A shredder bag that is shredded by a device, receives the shredded sugar cane on a second conveyor in the rear end of the vehicle body, and is detachably engaged with the rear end undulating rotation arm of the vehicle body by an appropriate means. In a sugarcane harvester in which the shredded sugarcane of the second conveyor is put in a box, a middle part of a scooping plate is rotatably attached to the front end of a lower end support frame of the spiral cylinder via a pin, and the scooping is attached to the frame. A structure in which the end of the plate is supported via shear pins is adopted.

[0014]

With the above construction, the sugar cane is caused by the rising spiral strip from the lower end of the rotating spiral cylinder to the middle of the upper part, and when the tip of the raised sugar cane reaches the reverse winding spiral strip, the reverse winding is performed. Further raising work of the tip of the sugar cane caused by the spiral strip stops. That is, the sugar cane tip is not caught on the rotation drive portion of the spiral tube, the support arm, or other portions.

When the tip of the scooping plate collides with root stones, sprinklers, gutters, etc. during sugar cane harvesting, a force is applied to the scooping plate in the direction in which the tip falls.

Then, the shear pins are sheared to release the end side support of the scooping plate, and the scooping plate with the end support released is
The tip falls and then falls backwards. That is, since it is inverted, damage to the vehicle body side is eliminated.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

(First Embodiment) As shown in FIG. 1, 11 is a self-propelled traveling vehicle body. The vehicle body 11 is provided with front wheels 12 and rear wheels 13 with a drive function on both front and rear sides, and is operated while operating in a front end cab 14 of the vehicle body 11.

Further, a sugar cane mowing device 15 is provided behind the front wheels 12.

In the case of the reaping device 15 shown in the figure, the rotary blades 16 are arranged on the left and right so that the opposite peripheral edges overlap each other, and the rotary blades 16 are rotated by hydraulic motors or the like while the vehicle body 11 travels to produce sugar cane. It is designed to cut the stems of.

It should be noted that the sugar cane just before being cut is the body 11
The inner side of the spiral cylinder 17 provided on both sides of the front end of the vehicle for rotation by a hydraulic motor or the like raises the vehicle body 11 upward.
Is pushed forward by the traveling of the vehicle and is collected by a feeding roller (not shown) into the vehicle body 11 in a front-back posture after mowing.

Furthermore, the sugar cane collected in the vehicle body 11 is
It is conveyed toward the rear inside the vehicle body 11 by the first conveying device 18. In the illustrated case, the first transfer device 18 has two upper and lower parts.
The set of driving rollers is arranged in the front and rear at a predetermined interval, and is sandwiched by the upper and lower rollers and conveyed.

Further, the sugar cane carried by the first carrying device 18 is cut into predetermined pieces by the cutting device 19. The above cutting device 19 is provided with a receiving roll that rotates downward and a rotary blade that has cutting blades that project upward at equal intervals in the radial direction side by side.

Further, behind the cutting device 19 in the vehicle body 11, there is provided a second conveying device 20 such as a belt or a net conveyor for receiving and carrying out the shredded sugar cane shredded by the cutting device 19.

The shredded sugar cane discharged from the head of the second transfer device 20 is a harvest bag hung on the rear end of the vehicle body 11 by an appropriate means so as to be detachably hung by a ring and a hook on an arm 21 which is turned up and down. It is put in 22 (a box may be used instead of a bag). In the illustrated case, the arm 21 is rotated up and down by mounting upward mounting plates 23 on both sides of the rear end of the vehicle body 11 and turning the ends of the two parallel arms 21 through pins 24 on the mounting plates 23. It is movably mounted, and a projection piece 25 connected from the lower end of one arm 21 and a tip of a cylinder 27 whose end is rotatably supported on the vehicle body 11 via a pin 26 are rotatably connected via a pin 28. The arms 21 are connected to each other, and the arms 21 are raised and lowered by the extension and contraction actions of the cylinder 27.

Further, as shown in FIGS. 1 and 2, the spiral cylinder 17 has a cylindrical body 32 whose upper and lower ends are rotatably supported and which is driven by a motor 31 such as hydraulic pressure connected to the upper end. The sugar cane raising spiral strip 33 provided from the lower end of the outer peripheral surface of the cylindrical body 32 to the middle of the upper portion, and the raising spiral strip extending from the upper end of the outer peripheral surface of the cylindrical body 32 toward the upper end of the spiral strip 33. In contrast to 33, it is composed of a reverse spiral helix 34.

With the above construction, when the sugar cane is raised by the raising spiral strip 33 of the spiral cylinder 17, and the raised sugar cane reaches the reverse winding spiral strip 34, the sugar cane produced by the reverse winding spiral strip 34 is Further raising work stops. That is, the sugar cane that stops in the upright direction stops between the rising spiral strip 33 and the reverse spiral strip 34. Therefore, the motor 31 at the tip of the sugar cane, the installation arm of the motor 31, and the vehicle body 11 are not caught.

In the figure, reference numeral 35 denotes an outer spiral cylinder provided so as to push the adjacent sugar cane to be cut off outside the spiral cylinder 17 to the outside (for releasing the entanglement, etc.).

(Second Embodiment) The sugar cane harvester is the same as that of the first embodiment, and detailed description thereof will be omitted.

As shown in FIG. 2, the front end of the frame 41, which supports the lower ends of the spiral cylinders 17, projects forward,
The middle of the tapered scooping plate 42 is rotatably attached via a pin 43.

The end of the scooping plate 42 is fixed to the frame 41 via a shear pin 44. As shown in Fig. 2, the posture of the scooping plate 42 fixed to the frame 41 via the shear pin 44 is such that the tip of the scooping board dives into the ground and scoops sugar cane that has fallen to the field due to the upper edge of the slope that climbs backward from the tip. Raise (raise while scooping).

As shown in FIG. 3, the shear pin 44 has a through hole 45 formed in the frame 41 and the scooping plate 42.
When the external force is applied to the scooping plate 42 by using a shaft (bolt) having a diameter smaller than that of the pin 43, only the shear pin 44 is sheared.

With the above construction, when the scooping plate 42 collides with root stones or water sprinkling equipment of the field during sugar cane harvesting, or when the scooping plate 42 collides with the gutter or the like when the sugar cane harvesting machine changes direction, the scooping plate 42 collides with the scooping plate 42. A strong impact force is applied in the tip descent direction.

Then, the shear pin 44 is sheared and the end of the scooping plate 42 is not fixed to the frame 41.

Therefore, as shown in FIG. 2, the scooping plate 42 is inverted from the solid line position to the chain line position.

As shown in FIG. 2, the ends of two upper and lower links 49 are rotatably attached to the support frame 47 of the spiral cylinder 17 and the frame 48 of the vehicle body 11 integrally with the frame 41. At the same time, the pin 53 supported in the middle of the upper link 49 is passed through the long hole 52 in the vertical direction of the tip of the piston shaft 51 of the cylinder 50 whose end is rotatably attached to the frame 48, and acts on the cylinder 50. If the weight on the side of the spiral cylinder 17 is supported (balanced) by the fluid pressure to be applied, even if an upward force is applied to each part as the inverted scooping plate 42 rides up, the pin 53 within the range of the elongated hole 52 rises. . That is, the frames 41, 4
7 is lifted to prevent excessive force from being applied to the vehicle body 11 side.

[0037]

Since the sugar cane harvester according to the present invention is constructed as described above, it is possible to prevent the tip of the sugar cane from being raised and cut. Therefore, the smooth cutting work can be continued, and the feeding into the vehicle body becomes smooth.

Further, since the scooping plate is turned upside down by cutting the shear pin, it is possible to eliminate damage to the mounting side of the scooping plate, the vehicle body side, the mounting pin and the like. Of course, troublesome repairs on the vehicle body side are unnecessary.
