Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled root vegetable harvester for digging and harvesting root vegetables such as radish and carrot.

[0002]

Conventionally, a multi-film is covered on a field scene where radishes and the like grow, and a coater for cutting the multi-film at the time of harvesting is attached to the harvester. However, simply cutting the film with a coulter at the time of harvesting a radish or the like using a harvester has a disadvantage that if the radish is larger than the planting hole of the film, the radish and the radish are spilled into the transport section of the harvester.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a root vegetable harvesting machine for harvesting a root vegetable that is to be planted in a field by sandwiching the foliage of the root vegetable with a pair of left and right pulling conveyors. In addition to providing a film cutting blade that cuts the surface, an auxiliary wheel that presses the side of the cutting part of the multi-film is provided, and when the multi-film is cut by the film cutting blade, lifting of the cut film is performed with the auxiliary wheel. In addition, the harvesting can be carried out favorably without the film being wound around the transporting body, and the transporting section of the harvester is supported by the auxiliary wheels with good strength to stably maintain the harvesting performance.

Further, the vibrating blade (10) is bent in an L-shape, and is supported on a swinging fulcrum shaft (36) projecting and fixed to the front right side of the machine base (3) so as to be able to swing back and forth in the middle. At the same time, an eccentric cam (38) and a hydraulic cylinder (3) serving as a crank rod are attached to an output shaft (37) from the engine (7) projecting rightward from a lower portion of a right side cover of the engine (7).
9), the upper end side of the vibration blade (10) is interlocked and connected, and the hydraulic cylinder (39) is reduced to thereby reduce the vibration blade (1).
0) is lifted above the ground, and the hydraulic cylinder (39) is extended, whereby the lower working side of the vibrating blade (10) is pushed into the soil, and the raising belt (17) (1) is raised.
7) and the pulling belts (19) and (19)
In this state, the oscillating blade (10) is configured to be oscillated back and forth by the crank motion of the eccentric cam (38).

The lateral transport body (13) is made of a flat belt, driven by a hydraulic motor (40), and pulled out of the transport body (11).
The radish (9), which has been pinched and transported to the rear of the fuselage, is transported to the left side of the fuselage.
Above the transport start end, a cusp (tapered end) (9b) opposite to the foliage (9a) of the radish (9) that has been nipped and transported
And a gutter (41) having an arcuate cross section for temporarily holding the pointed head (9b) is provided rotatably. As shown in FIG. 6, the receiving gutter (41) faces the longitudinal direction of the transport body (11) in a forward extension line from the feed end of the transport body (11).
A gutter (4) is provided on the pivot shaft (42) in the front-rear direction which is offset by a fixed distance (L) to one side from the transport center line of 1).
The back side of 1) is rotatably supported, and a spring (4
3) The gutter (41) is brought into contact with the stopper (44) by force to make the curved receiving surface (41a) of the gutter (41) face the upper transport center line, and the left and right holding belts (24) (24) When the radish (9) to be clamped is transported to the feed end, the radish (9) is not directly lowered to the horizontal transporting body (13), but is temporarily inserted into the trough (41). When the foliage section (9a) is released from the holding of the holding belts (24) and (24) while holding the bristles 9b), the gutter (41) is rotated by its own weight, and the tip of the radish (9) is rotated. The horizontal conveyance body (13) is configured to be smoothly transferred to the horizontal conveyance body (13) in a substantially horizontal posture in the front-rear direction with the (9b) side being the front.

A rotary disk-type first cutter (46) driven by an electric motor (45) and a blower (47) are provided at a position near the feed end of the pull-out carrier (11). (11) The tip of the foliage (9a) that has largely protruded upward from above is cut with a cutter (46), and the cut foliage is blown off with a blower (47).
The first cutter (46) is arranged in the air path cover (48) of the blower (47), and the foliage cut by the cutter (46) falls from the foliage discharge gutter (49) communicating with the cover (48). When the radish (9) is released from the pull-out carrier (11) to the horizontal carrier (13) and is inherited, the inherited posture is prevented from being disturbed by the catch of the tip of the foliage (9a). ing.

Further, a radish (9) conveyed by the conveying body (13) is located at a rear position at an intermediate portion of the horizontal conveying body (13).
A rotary disk-shaped second cutter (51) driven by an electric motor (50) for further cutting the foliage (9a) of the stalk to a fixed length
Is provided so that the cut length of the foliage (9a) of the radish (9) is accurately adjusted to a substantially constant length.

By the way, as shown in FIG. 5, a multi-film (52) laid on a ridge of a field where a radish (9) is planted.
Is cut by a coulter (53), which is a film cutting blade. The coulter (53) is arranged on the conveyance center line on the feed start end side of the drawing conveyance body (11), and is fixed to the upper frame (21). A rotating shaft (57) of the coulter (53) is connected to and supported by a holder (54) to be provided via a vertical position adjusting bolt (55) and a support frame (56). The auxiliary wheel (5) pressing the multi-film (52)
8) is integrally and rotatably provided beside the rotating shaft (57) on the side of the coulter (53), and the lifting of the film (52) cut by the coulter (53) is performed by the auxiliary wheels (58). Prevention and pull-out carrier (11)
Is supported by an auxiliary wheel (58), and the transport body (1) is
It is configured to improve the support strength of 1). In this case, if the radish (9) is larger than the planting hole of the film (52) by simply cutting the multi-film (52) in a straight line with the coulter (53), the radish (9) is clamped by the carrier (11). At this time, there is a disadvantage that the film (52) is wound around the transport body (11), but the disadvantage is solved by pressing the film (52) with the auxiliary wheel (58).

8) a flexible container stand (79) provided with a transport roller (69) foldably provided on one side of the machine via a flexible container stand (7);
9) is provided with an auxiliary wheel (58) that is connected to the vertical movement via an electric cylinder (80) and a ground pressure sensor (81) that detects a change in the ground pressure of the auxiliary wheel (58).
8) When the relative pressure between the flexible container stand (79) on which the 8) is mounted and the ground changes, the contact pressure of the auxiliary wheels (58) changes.
With the control of the electric cylinder (80), the ground pressure of the auxiliary wheel (58) is kept constant, and the left-right balance of the body is stably maintained even under the working condition in which the large capacity flexible container (68) is mounted. It is.

[0016]

As is apparent from the above examples, the present invention provides a root vegetable harvesting method in which the foliage (9a) of the root vegetable (9) planted in a field is clamped by a pair of left and right pulling transporters (11). In the machine, a film cutting blade (53) for cutting a planting surface of a multi-film (52) laid in a field was provided, and an auxiliary wheel (58) for pressing a cut portion side of the multi-film (52) was provided. Therefore, when cutting the multi-film (52) with the film cutting blade (53),
