Description

  The present invention is connected to the rear part of the tractor, and when harvesting long roots of long pods and beef pods grown on the straw of the field, a digging member is inserted into the lower end of the root vegetables to grow the root vegetables around The present invention relates to a neck raising device that clearly projects the neck (also referred to as the head) of root vegetables immediately before introducing a harvesting machine in a harvesting system that digs while floating with soil.

Various digging apparatuses for long-root vegetables such as long peach and beef bowl have been proposed. Stem and leaf treatment is known as a pre-operation before the introduction of the harvester of the long-root beef bowl, and a winding device for matured and dead vines has been proposed before the introduction of the long harvester. For example, in a beef bran forage processing machine, a technique is disclosed in which the soil around the neck (also referred to as the head) of the root vegetable is moved to the side to expose the root vegetable neck so that the planting position can be easily confirmed during the digging operation. (Patent Document 1).
In addition, a screw auger type earth remover that moves the upper soil around the roots of root vegetables to the side in front of a long digging body reduces the traction load of the digging body and reduces it. A technique that enables digging work even with a tractor with tow horsepower is disclosed (Patent Document 2).

'' To remove the surface soil, the soil removal board with a V-shaped inclined surface in plan view will damage the head part if the root part of the root vegetable is cut directly. There is a limit. Japanese Patent Laid-Open No. 5-123022 discloses a digging body attached to a tractor by positioning a soil removal machine for carrying out the upper layer soil around the root part of the root vegetables to the side in front of the digging body. A technique for reducing the traction load is disclosed, but there is no description regarding neck exposure.
The object of the present invention is to remove the surface soil around the neck (head) of the long-rooted vegetables as a pretreatment step for digging out the long-rooted vegetables, and to clearly expose the head itself so that the planting position of the root vegetables can be determined. It is an object of the present invention to provide a long-root root crop necking device that is easily confirmed so that the digging body at the time of digging work is accurately placed at the root vegetable planting position.

In the present invention, a plurality of rake wires are arranged to form a rake row, and the rake row is arranged in a radial direction with respect to a rotation axis orthogonal to the traveling direction to constitute a rake group rotating body. The body is a long-root root cropping device that scrapes the surface soil of the long-root root vegetable cultivation sideways while reversing it so as to scoop up from below with respect to the direction of travel.
Further, in the above-described long-root root cropping device, the rotatory axis of the rake group rotating body includes a means for changing the angle with respect to the traveling direction.

  Because it is configured as above, the neck itself is clearly clarified by loosening the beef bowl of root vegetables grown as a pretreatment of the long-root root vegetables and the surface soil around the long neck (head). The planting position of the root vegetables can be easily confirmed, and the operator of the tractor can accurately place the digging body at the planting position of the root vegetables. Furthermore, the tractor's traction force can be reduced at the time of the next digging work by the amount of the surface soil that has been eliminated, which is economical. Further, the rotation axis of the rake group rotating body is efficient because the position of the scraping fill is changed by changing the angle with respect to the traveling direction, and the condition can be selected as the adjacent work condition of the ridge.
