DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for harvesting heavy root vegetables such as burdock with relatively long roots.

[0002]

2. Description of the Related Art A conventional root crop harvesting machine is disclosed in
No. 268816 is known. According to this known technique,
It is equipped with a horizontal twisting transport device, a leaf cutting device, an alignment device, a collection container, etc., which pull out the root vegetables and transport them while holding the stem portion, and change the vertical position to the lying position.

[0003]

The above-mentioned known harvester is suitable for a large-scale field, but in a small-scale and small-area field of an individual, it is poor in small-turning property and becomes an expensive device, which is economical. Is also disadvantageous.

[0004]

Means for Solving the Problems To solve the above-mentioned problems, in a root vegetable harvesting device such as a burdock, in which an excavator and a transfer device having a pair of right and left transfer bodies are arranged at an angle,
The transporter is driven through an intermediate shaft from an input shaft transmitted from the tractor PTO shaft, and the root of the root vegetable abuts while the root vegetable is being raised while the root vegetable is being lifted following the extraction of the root vegetable by the transporter. The burdock and the like were characterized in that the posture was inclined, and a dropper was arranged that was continuously aligned longitudinally when the root of the root vegetable was released at the end of the carrier, and then automatically discharged to one side after a fixed amount of storage. A root crop harvesting device is provided.

According to the root vegetable harvesting machine constructed as described above, the root vegetables are excavated and dug out, and after being extracted, the root vegetables are continuously stored in the longitudinal direction in the traveling direction, and automatically when the set weight is reached. Is discharged to one side. Therefore, since the transporting and moving device, the aligning device, the storage container, and the like are eliminated, the structure is simple and the small turning property is good. After harvesting, the work will be picking up only at the discharge location.

A crank 14 has an upper portion connected to the cam boss 18, and a lower portion is bifurcated and pivotally connected to a middle portion of the spatula 12 by a pin, and swings the spatula up and down by the eccentricity of the cam boss 18. .

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 connected to the furk 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 part of the transfer 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 body 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.

Reference numeral 26 denotes a dropper device, and the vertical frame 2
7 support in the front-rear direction. The base of the vertical frame 27 is appropriately supported by the support frame 2. Reference numeral 39 denotes a guide wheel, which is lifted up by the transport body 7 and
When the roots of the root vegetables abut, the vertical posture is inclined,
When the root of the root vegetables is released at the end of the above, the root vegetables are aligned in the front-rear direction and stored as shown.

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 on the outer periphery of a horizontal pipe 16 forming the main frame 1 in a lateral direction. . In this embodiment, one side is fixed to the main frame 1 and is operated by the hydraulic cylinder 22. Reference numeral 13 denotes a pair of beams fixed to the support pipe 21.

FIG. 3 is a rear view of the dropper device 26, and FIG.
Shows a side view thereof. Side plates 35 and 35 'are provided on the front and rear sides of the vertical frame 27, and the main shaft 29 is mounted on the lower part. Numeral 28 denotes receiving members which are appropriately arranged in several rows in an arcuate shape when viewed from the rear, and the ends of which are swing brackets 30,
It is supported by 31 ′ and rotatably supported on the main shaft 29.

A spring body 33 is provided below the swing bracket 30.
Is fixed to one end, and the other end is fixed to an adjusting screw 32 provided on an upper portion of the side plate 35. The elasticity of the spring body 33 is determined by the expansion and contraction of the adjusting screw 32. 31 is a stopper provided inside the side plate 35, the upper surface of the swing bracket 30 abuts,
It is elastically attached by the spring body 33 described above. The adjustment of the spring body 33 is determined in advance by the size of the bundle of root vegetables.

FIG. 5 is a plan view of the transport section, in which a pair of transport bodies 7 are inclined rearward in a parallel manner in a rearward direction, input from a transmission case 8 and driven through an intermediate pulley 11. The dropper device 26 is suspended via a vertical frame 27, and the receiving materials 28 are arranged perpendicularly and parallel to each other. As described above, when a fixed amount is stored, it turns and discharges the root vegetables to one side.

FIGS. 6 and 7 show another embodiment of the dropper device. When a certain root vegetable is mounted on the receiving member 28, the first spring 37 is initially extended, and the wire is pulled and engaged. The pin 34 is released from the fixed portion of the swing bracket 30, and the receiving member 28 and the swing bracket are turned at once and the root vegetables are discharged. When the root vegetables have been discharged, the receiving member 28 and the swing bracket 30 are returned to the initial state by the spring body 33. According to this embodiment, the predetermined amount of root vegetables loaded on the receiving material 28 is sensed by the first spring 37 and discharged instantaneously.

[0018]

According to the above construction, the super deep cultivation (8
Even root vegetables of long roots such as burdock cultivated at 0 to 100 cm) are floated with low horsepower, continuously and reliably pinched by a carrier, extracted and then stored in a certain amount in the direction of travel. Since it is discharged and left one by one, it is possible to collect and collect work in a later process, thereby improving the efficiency of the harvesting work, and at the same time, it is possible to produce the apparatus itself simply and lightly.
