Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a weeding structure of a strawberries harvester that raises and harvests strawberries while weeding them.
The present invention relates to a weeding structure of a straw harvester in which a sward rotating body is arranged in a rearwardly tilted posture from the vicinity of the front ground of the stalk-and-culm raising device obliquely inclined in the rearwardly tilted posture.

[Prior Art] As a vegetative structure of a straw harvester, for example, JP-A-63-1
As disclosed in Japanese Patent No. 48921, the stem culm raising device obliquely installed in a rearward tilted posture extends from near the front ground of the stalk culm raising device rearward and upward and near the front of the stalk culm raising device, and is looser than the stem culm raising device. It is generally proposed that a rotator is arranged in a backward tilting posture. As the rotator, two relatively small diameter rods with pipes loosely fitted are spread upward in a side view. In addition to arranging in a triangular shape, an upper taper cone-shaped drum is connected and arranged on the upper end side to support the lower end of the above weed rotator by bearing, and the upper end is connected to the driving shaft for rotation. Was configured to drive.

[Problems to be Solved by the Invention]

In the above-mentioned conventional structure, since the weeding body is swayed by rotating the weeding rotor made of a small-diameter rod material arranged in a triangular shape with an upward spread in a side view, an upward spread portion of a triangular shape, that is, an orbital radius. In a large area, the sward-rotating body comes into contact with the straw grass at a large rotation peripheral speed with a large amplitude.

The contact with a large amplitude using such a bar material causes a stronger collision with the straw grass as the rotation speed becomes faster, and it is easy to cause many broken scratches on the straw blade of the straw grass to deteriorate the quality.
In order to avoid this, if the rotation speed is sufficiently reduced to rotate slowly, the soft straw straw grass cling to the grass body, and the grass itself is difficult to perform sufficiently. In particular, it is difficult to unwind the wrapping of the straw grass at a portion with a small revolution radius near the lower end of the turning radius, and the range of the effective loosening action on the entwined straw grass is a small part in the longitudinal direction of the rotator. However, when the entanglement is tight, it tends to be difficult to harvest while slicing well.

In addition, the upper tapered taper cone-shaped drum itself of the upper part of the sward rotating body does not have a rotating shunting function, and only exerts a stalk-culm guide function, so it is forcibly raised by the claws without entwining the strawberries with each other. There is a possibility that it may be pulled up and broken or damaged.

The present invention has been made by paying attention to such a point, and eliminates the above problems by improving the weeding structure including a weeding body, and smooth and good even under tightly entangled conditions. The purpose is to enable harvesting with hay.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the characteristic configuration of the present invention is to dispose a sward-rotating body in a rearward tilted posture from the vicinity of the front ground of the stem culm raising device obliquely installed in the rearward tilted posture to the rearward and rearward inclined posture. In the weeding structure of a straw harvester, the guide edge extending from the tip to the rear side is projected laterally outward at a position on the lateral side of the fuselage on the uncut side of the rotator. In addition to installing a grass rod,
The stem culm raising device is arranged in a tilted rearward posture that is looser than the stem-culm raising device, and is rotatably arranged around a rotation axis center following the tilted inclination posture. Are different from each other in two directions orthogonal to each other, and the outer edge of the portion far from the axis of rotation is composed of a rigid member that is formed into a smooth curved surface along the circle of rotation locus, Is formed linearly in the direction of the axis of rotation such that the circle of its rotation locus has a substantially constant diameter from the front end to the rear end, and the stem culm raising device and the rotator are The point is that it is configured so as to be able to oscillate up and down around a horizontal axis in the lower rear portion without changing the positional relationship with each other.

[Action]

The vegetative rotator is entwined with the front, rear, left and right while giving a vibration with a relatively small amplitude due to the difference in the rotation radius to the planting straw grass while rotating around the axis along the longitudinal direction. Can be sown. In other words, while supporting the strawberries up to its final unit with the rotator, the contact with the strawberries in two places on the left and right, and small vibrations are given by rotation, whereby the front and back, left and right entanglements of the straw stems, which are soft stems, are entangled. Can be smoothly and smoothly unraveled, and since the part that gives vibration by hitting the strawberries is formed into a smooth curved surface along the rotation trajectory, rotate it at high speed to cause small vibrations. Also, there is little risk of damaging the straw grass, and this entanglement can be effectively disentangled by high-speed vibration.

Moreover, the vibrating action caused by the difference in the radius of gyration is that the rigid member forming the weeding rotor has a straight line in the direction of the axis of rotation so that the rotation locus has a substantially constant diameter from the front end to the rear end. Since it is formed into a shape, it is carried out over almost the entire length of the range of placement of the turf rotating body, and the range where the effective loosening function by this small vibration is exhibited is It can be set in a wide range over almost the whole.

In addition, at the position of the side of the fuselage on the uncut side of the rotator,
As the weed rod is provided with the guide edge extending from the tip toward the rear toward the lateral outer side, the degree of vibration imparted to the weed rotor itself depends on the whole range of the weed rotor installation range. Even if it is constant over a period of time, it is possible to gradually increase the function of the weeds for the target strawberry plant until the end of the weeding action. In other words, if there is entanglement in the target vegetation by the rotator, the one located on the uncut side of the entwined vegetation has the action of pushing out to the lateral outer side by the weeding rod in addition to the vibration. Is gradually added. As a result, the pushing action to the lateral and lateral sides is gradually strengthened as the aircraft progresses, and the vegetation action due to small vibrations is received. Synergistic with the separating action, effective weeding is performed.

Furthermore, when the entanglement between the strawberries is tight, the stem and culm raising device and the rotator are driven and moved up and down around the horizontal axis of the rear lower part at an appropriate amplitude and cycle without changing their positional relationship. As a result, while swinging the strawberries up and down, a vibrating weeding action by the rotator and a separating action by pushing the weeding rods are given, so that reasonably smooth weeding and raising can be performed.

〔The invention's effect〕

As described above, according to the present invention, a small vibration effect due to uniform rotation over the entire length of the weeding rotator, smoothly and properly weeds the planting strawberries without damage or wrapping, and is given simultaneously. By synergizing with the pushing action of the grass rod, it is possible to obtain even better weeding performance, and it is possible to harvest the strawberries, which are the products of the stem stem itself, in a high quality state with little breakage or damage. became.

In addition, in addition to this, the stem and culm raising device and the rotator of the above weeds are swayed up and down without changing the positional relationship of each other, so that even when the entanglement is strong, weeding and raising are reasonably performed. It became possible to carry out a good harvest without breaking or pulling out.
