DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine for digging and harvesting root crops such as burdock by ultra deep cultivation.

[0002]

2. Description of the Related Art Conventional root crop harvesters are disclosed in
No. 49507 is known, which attempts to pinch and convey root crops floating on a vibration excavation body.

[0003]

When the known harvester described above is used for excavating burdock, etc., which has been super-deeply cultivated (90 to 100 cm), the excavated body for vibrating the bottom of the root vegetable to a flat surface requires a horsepower. In addition to the above, there are drawbacks in that not only is the size increased, but also the amount of moving soil becomes large, and root vegetables fall down during vibration, making it difficult to guide to the holding portion.

In order to solve the above-mentioned problems, a horizontal pipe suspended on a main frame, a pair of support plates supported by the horizontal pipe, a beam provided to be suspended on the pair of support plates, and a lower portion connected to a spatula. An excavator support section consisting of a crank that swings the spatula up and down, and a pair of spatula with an inverted octagonal shape in front view as it is supported by the beam and the crank and swings up and down and rises backwards and rises backwards Drilling rig,
And has a transport device that is disposed inclined and has a pair of left and right transport bodies whose starting end is close to the ground surface and floats so as to sandwich the root vegetables from the left and right, and further lifts the root vegetables that have been lifted up rearward. A root vegetable harvest, wherein the rear ends of a pair of spatula of an excavator and the front end of a transport body of a transport device are superimposed in a side view, and the root vegetable raised at the rear end of the spatula is placed and the root vegetable is pinched and moved. Suggest a machine.

[0005]

[Function] According to the root vegetable harvesting machine constructed as described above, it is possible to lift even small root vegetables such as burdock by deepening tillage with small horsepower, and the root vegetables are sandwiched by a spatula when floating. It does not fall down, so that it is continuously held by the transporting body and acts so as to be reliably pulled out. In addition, when the necking means is provided, the topsoil of the root of the root vegetable is eliminated, so that the clamping action is further ensured.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a longitudinal sectional view showing the embodiment of the present invention. Reference numeral 1 denotes a main frame, which is attached to a three-point link of a tractor (not shown). Reference numeral 16 denotes a horizontal pipe which is horizontally mounted on the main frame 1. Reference numeral 17 denotes a pair of support plates, which are arranged in front and rear, and slide on the outer periphery of the horizontal pipe 16. The beam 13 is provided at the rear of the pair of support plates 17 so as to hang downward. A beam 13 constituting the excavator 3 is provided with a spatula 12 rising rearward toward the rear, and is arranged in an inverted octagonal shape when viewed from the front.

Reference numeral 9 denotes an input shaft, which is fixed to the upper portion of the support plate 17, the input is transmitted from the PTO shaft of the tractor at the front, and the output pulley, the cam boss 18 and the cam pulley 19 are mounted at the rear.

Reference numeral 14 denotes a crank, which is connected to the cam boss 18 at the upper portion, and has a bifurcated lower portion. The lower portion is pivotally connected to the middle of the page (3) spatula 12 with a pin. Swing up and down.

Reference numeral 10 denotes an intermediate shaft, which is disposed above a rear portion of the support plate 17. The intermediate shaft 10 is transmitted from the input shaft 9 at the front and rotates the cam pulley 19 at the rear. The rear end of the intermediate shaft 10 is a fork 1
5 is rotatably supported on the base of the slider 20. When the cam pulley 19 rotates, the eccentric cam roller swings the slider 20 right and left.

Reference numeral 2 denotes a support frame, the front of which is fixed to the support plate 17, and the rear end of which is fixed to the rear of the transport device 25. The transporting device 25 includes a pair of right and left transporting bodies 7, the starting end of which is close to the ground surface and is disposed in an inclined manner. This start end is disposed so as to overlap with the rear end of the spatula 12 in a side view.

Reference numeral 8 denotes a transmission case, which drives the carrier 7. The input is inputted from the intermediate shaft 10 via the universal joint 6, and the intermediate pulley 11 drives the left and right rotating shafts of the carrier 7. Reference numeral 5 denotes an elastic material, which expands and contracts by the elastic body, and the tail wheel 24 follows the unevenness of the furrow to make the height of the holding start end of the carrier 7 constant.

FIG. 2 is a sectional view of a support portion of the excavator. A support pipe 21 connecting left and right support plates 17 and 17 'slides laterally on an outer periphery of a horizontal pipe 16 forming the main frame 1. . In this embodiment, one side is fixed to the main frame 1 and is operated by the hydraulic cylinder 22.

FIG. 3 is a rear view for explaining the necking means 4. The base of the slider 20 is rotatably supported on the intermediate shaft 10, and the eccentric cam roller provided on the cam pulley 19 slides in the inner groove of the slider 20. To swing the fork 15.

FIG. 4 is a plan view of the spatula 12. The spatula 12 having an inverted octagonal shape when viewed from the front has the root vegetables sandwiched therebetween and overlaps with the starting end of the carrier 7 at the rear end in a side view. The lifted root vegetables are moved and squeezed by the carrier 7 at a position on the rear end of the spatula 12. 23 is a guide member, which assists the root vegetables to the starting end of the transporting body 7.

FIG. 5 is a plan view of the transfer device.

[0016] With the above construction, the super deep tillage (80
Even root vegetables of long diameter such as burdock cultivated at ~ 100 cm) are floated with low horsepower and are continuously and reliably held by the carrier.
Harvesting has become extremely efficient since it is extracted.
