Abstract

PURPOSE:To provide a harvester capable of digging up root vegetables cultivated by the extremely deep plowing such as a burdock and continuously uprooting the root vegetables with a carrying conveyor. CONSTITUTION:This harvester for root vegetables is constituted by installing a pair of beams 13 and a pair of spade units at the lower end of the beams 13 in the form of an inverted chevron so as to oppose thereto when viewed from the front and setting the rear ends of the pair of the spade units tilted so as to rise toward the rear in positions at the same or a higher level than that of the starting ends of conveying units 7. Thereby, the neck part of a root vegetable 38 floated together with soil is surely guided to the starting ends of the conveying units 7, made to collide therewith and held therein.

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As a conventional root crop harvesting machine, it is known that the harvesting of root vegetables is carried out.
No. 22423 is known, and especially for soft crops such as yams and radishes that are to be dug up, in order to arrange them in an inverted eight shape on both sides, tilt the main body of the go downward from the rear toward the front. At the same time, the blade tips are inclined downwards toward each other in the opposite direction and are arranged on the main body of the go, and an appropriate length of the earth receiving rod is projected horizontally rearward on the upper rear surface of the main body of the go. It is a soft crop digging machine characterized by being formed. Further, Japanese Laid-Open Patent Publication No. 2-49507 is known, but this known technique allows a vibration excavation body for floating root vegetables and a suspension of the floating root vegetables before they are submerged. It is the one.

[Problems to be Solved by the Invention]

Page (2) The above-mentioned Jitsuhei 1-222423 is intended to prevent damage to soft crops such as yam and radish at the time of digging, and to raise it to the surface of the soil by the earth pressure of the excavated soil, and then the lower half. The work of extracting and collecting the remains. In addition, JP-A-2
No.-49507 is equipped with a conveyor that holds and conveys the floated root vegetables at the carry-in section. When this is introduced into the digging of super-deep cultivated burdock, the vibration excavated body causes the soil around the burdock However, since the height at which the burdock is floated is small, it is difficult to continuously hold the neck of the burdock.
Also, even if a wide excavation body is extended and inclined, excavation resistance may become too large and it may be difficult to drive. Also, even if the upper half of the burdock etc. is exposed, play left and right. There is also a problem of staying because it does not fit in the center of the conveyor.

[0004]

In order to solve the above problems, a pair of beams and a pair of gobs at the lower ends of the beams are provided so as to oppose each other in an inverted eight shape in a front view. The rear edge sloping to the rear of the body is configured to be positioned above the start end of the pair of conveyor belts, including at least the upper end, and the pair of gobs dig up root vegetables from the lower and upper sides of the soil, The root vegetable harvester is characterized in that the root pressure is raised to the surface of the soil by the pressure of the soil that is dug up, and the neck portion of the root vegetable is continuously held by a conveyor belt and pulled out. Further, the above-mentioned root vegetable harvesting machine is characterized in that the pair of gobs are configured to be swingable at the lower end of the beam.

[0005]

[Function] A pair of arms are provided at the lower end of the beam so as to oppose each other in an inverted octagonal shape when viewed in the front-rear direction. Act to lift upwards,
The root crops float up to lift the soil. At this time, since the rear end edges of the pair of gobs tilted upwards are positioned above the start ends of the pair of conveyor belts including at least the same level, the soil is lifted in a state of being raised. The neck of the root vegetables that came is moved to the surface of the soil (3) and then collided so as to drop to the starting end of the conveyor belt, and is securely held. The conveyor belt holding the root vegetables rotates backwards at high speed to extract the root vegetables.
Further, since the gobo swings up and down, the soil around the root vegetables is loosened and floated up, so that the neck portion of the root vegetables is naturally exposed and can be easily held.
