DISCLOSURE OF THE INVENTION According to the present invention, a non-heading leafy vegetable Y cultivated on a flat ridge in a vinyl house is slid left and right on a pretreatment section A, and a traveling section B is at the same position. The present invention relates to a mechanism for finishing the harvest of non-heading leafy vegetables Y on flat ridges while traveling back and forth in several times. In addition, the digging / harvesting mechanism of the non-heading leafy vegetables Y is constituted by a mechanism such as soil removal, root alignment, and transfer of the top of the plant. Further, the non-ball headed leafy vegetables Y are configured not to drop from the gap at the joint portion of the soil removing belt 3 and the root aligning plate 4. Further, the drive motors of the pretreatment unit A and the traveling unit B are separately configured, and the sliding mechanism of the pretreatment unit A with respect to the traveling unit B is simplified.

[0004]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. In the claim 1, in the non-heading leafy vegetable harvester in which the pretreatment unit A is slidable right and left on the front of the traveling unit B, the pretreatment unit A and the traveling unit B are driven by separate drive motors. The pretreatment unit A is attached to the drive unit sliding plate 29, and the drive unit sliding plate 29 slides on the pretreatment unit slide frame provided on the traveling unit B in the left-right direction, so that the traveling unit B is moved. It is slidable with respect to.

In the second aspect, the pretreatment drive motor M is fixed to the drive portion sliding plate 29, and the power is transmitted from the pretreatment drive motor M to the drive bevel gear box 18.
In the drive bevel gear box 18, the leaf engaging conveyor belt 2, the root upper conveyor belt 5 and the soil removal belt 3 are branched to transmit power, and the root lowering belt 6 is driven from the root upper conveyor belt 5. It is composed.

According to the third aspect of the present invention, in the non-heading leafy vegetable harvesting machine in which the pretreatment section A is slidable right and left on the front section of the traveling section B, the pretreatment section A is located behind the vibration excavating blade 8. The soil removing belt 3 is disposed on the rear side of the soil removing belt 3, and the root aligning plate 4 and the root pulling down belt 6 are vertically overlapped on the rear portion of the soil removing belt 3.

1, 2 and 3, the overall structure of the non-heading leafy vegetable harvester will be described. The front two wheels 28, 28 and the rear two wheels 27, 27 are pivotally supported on the body frame F,
It constitutes a four-wheeled traveling section B. The fuselage frame F is
It is composed of the left and right wheel frames 30, 30 and the work frame 43, etc., and the work table G is fixedly installed on the upper surface of the left and right work frames 43, and the forward and reverse transport belt V is supported on the front part of the work frame 43. is doing. The non-heading leafy vegetable storage box 26 is placed on the workbench G at the rear of the transport belt V capable of reversing forward and backward.
・ 26 is placed. The non-heading leafy vegetable storage box 26.
26 is configured to be bundled every fixed number of stocks and to be arranged and loaded in a bundled state.

The forward / reverse transport belt V is changed in rotation depending on whether the position of the pretreatment section A is left or right, and either the left or right operator sorts out the dug stocks. On the other hand, it is configured to be transported to the other side by a transport belt V that can be rotated in the forward and reverse directions, and an operator on the other side can bundle or bundle the transport belt V. A battery T and a traveling drive motor N are arranged between the two rear wheels 27, 27. A drive chain case 44 for transmitting the rotation of the traveling drive motor N to the rear two wheels 27, 27 is provided. Further, since there is no steering mechanism at the rear part of the machine body frame F, a steering handle 46 operated by the operator is provided.

Work frame 43 and wheel frame 30.3
The vertical frames 34, 36 are interposed between 0, and the seat support frame 35 projects upward from the wheel frames 30, 30 at an intermediate position in the front and rear of the vertical frames 34, 36.
And a seat 1L.1 by the seat support frame 35.
Supports R. Further, a pretreatment slide frame 31 is installed between the front portions of the left and right work frames 43, and a reinforcing frame 45 is also interposed between the left and right vertical frames 34. The pretreatment slide frame 3

Therefore, only the root portion projects downward from the groove gap, the root portion is sandwiched by the root pull-down belt 6, and the root pull-down belt 6 is arranged so as to be gradually inclined away from the root alignment plate 4. Therefore, pull the root part of the non-heading leafy vegetables downward until the bottom end of the non-heading leafy vegetables comes in contact with the top of the non-heading leafy vegetables, and then the root cutting blade. When cutting with 12, the non-heading leafy vegetables are positioned. The root upper carrying belt 5 is extended at the position of the rear end of the root aligning plate 4, and the non-heading leafy vegetables whose roots are cut by the root cutting blade 12 are clamped by the root upper carrying belt 5. , Between the biasing springs 49.

The lower leaf processing roller D, which is nipped by the upper conveyor belt 5 and passed through the biasing spring 49, is rotated by the lower leaf treatment roller D, which can be formed during the growth of non-heading leafy vegetables. With respect to the finished lower leaf portion, the leaf portion of the non-heading leafy vegetables is locked by the leaf engaging transport belt 2 and the root portion is sandwiched by the plant upper transport belt 5, and the lower leaf treatment is performed. It is configured to be removed by the roller D. The lower leaf processing roller D is driven by another motor. The non-heading leafy vegetables that have been engaged by the leaf-portion engaging conveyor belt 2 above and passed through the stocker upper conveyor belt 5 are finally moved to the front of the operator by the horizontal conveyor 7 composed of a flat belt. To be made.

FIG. 9 discloses a structure in which the rear end of the dirt removing belt 3 and the front end of the root pulling down belt 6 are overlapped with each other, and the root aligning plate 4 is overlapped thereon. The root aligning plate 4 has a structure in which a groove through which a root can pass is provided between two positions, and the leaf portion of the non-heading leafy vegetable Y cannot pass through the groove. Therefore, only the root portion is sandwiched by the root pulling belt 6 and pulled down to align the roots of the non-heading leafy vegetables Y. In this structure, the soil removal belt 3 is configured to be extended downward by a flat pulley 70 and a downward extension flat pulley 71,
A driven pulley 19 around which the root pull-down belt 6 is wound is supported on it. Therefore, the root pull-down belt 6
The tip of the lap overlaps the soil removing belt 3 by a length m. Further, the tip of the root alignment plate 4 overlaps and overlaps so that the tip is located above the flat pulley 70.

FIG. 10 discloses the structure of the drive unit slide plate 29 which is slidable on the pretreatment unit slide frame 31 and the reinforcing frame 45 provided in the traveling unit B. A pretreatment drive motor M is fixed to the drive portion sliding plate 29, and a chain is wound around the drive bevel gearbox 18 by the pretreatment drive motor M to transmit power. The drive part sliding plate 29 is provided with a sliding hook 74 on the upper part and a sliding engagement plate 47 on the lower part.
4 is attached to the slide frame 31 of the pretreatment section and the sliding engagement plate 47.
