Description

[Detailed description of the invention] [Industrial field of application] This invention is designed to enable durable use of the fork-shaped lifter of a beet harvester.

[Conventional technology]

As shown in Figure 4, the fork-type lifter of a conventional beet harvester lifts a steel plate with a thickness of about 5 mm to 1/2.
A bar bent into a 4-arc shape (A), a bar further deformed into an arc shape (eight-figure shape in plane), or a round bar bent into an arc (B) were used, but the former The latter suffers from severe wear and has low strength, and the latter has disadvantages such as increased traction resistance because it requires burying the area below the horizontal center line C and digging it out above the horizontal center line. It is something.

[Problem that the invention attempts to solve]

This idea attempts to solve the problems of heavy wear and low strength, and the problem of increased traction resistance.

[Means for solving problems]

Position the lifter at the excavation opening with the 1/4 arc part of the steel material made by dividing the round bar into 4 parts facing inward and upward.
This problem was solved by curving the tip outward and expanding it into a symmetrical eight-shaped shape to reduce wear and provide strength.

[Effect]

The 1/4 arc part of the steel material, which is made by dividing a round bar into four parts, is positioned upward and inward, and the tip is curved outward to form a figure-eight shape on the plane, resulting in less wear and a wider flat surface on the lower surface of the fork-shaped lifter. Therefore, the plowing depth is small, so the traction resistance is also low and it can be used.

〔Example〕

The beets are dug up at the digging opening 1, held between upper and lower diagonal feeding rod conveyors 2 and 3, and sent to the horizontal rod conveyor 4 at the rear. a harvester 5 which sends beets to a tank 8 from an annular conveyor 6 via an upper rod conveyor 7;
, attach the lifter 9 of the digging opening 1 to the round bar 15.
A 1/4 arcuate section 10 of a steel material divided into four parts is positioned facing inward and upward, and the tip is curved outward to form a bilaterally symmetrical 8-shape in plan view.

Reference numeral 11 is a pulley for winding the lower oblique feeding rod conveyor 3, and reference numeral 12 is a lifter frame to which the lifter 9 is attached via a plate 14 to the tip. Reference numeral 13 indicates a connecting support rod of the frame 12 for the left and right lifters 9.

[Effects] The lifter is divided into four round rods, and the 1/4 arc part is positioned upwards inward, making the lower surface a horizontal surface and making the entire body solid, which reduces wear and reduces traction resistance, and because it is solid. It has effects such as strength.

[Brief explanation of drawings]

FIG. 1 is a side view of the entire beet harvester, FIG. 2 is a plan view of the lifter of the present invention, FIG. 3 is a longitudinal sectional view thereof, and FIGS. 4 and 5 are sectional views of a conventional lifter.

Claims (1)

[Scope of utility model registration request] The beets are dug up at the digging opening, held between upper and lower diagonal feeding rod conveyors, and sent to the horizontal rod conveyor at the rear. In a beet harvester that feeds beets into a tank via an upper rod conveyor, the lifter at the digging opening is positioned so that the 1/4 arc section of the steel material, which is made by dividing a round bar into quarters, faces inward and upward, and the tip faces outward. A fork-shaped lifter for a beet harvester characterized by being curved and spread out in a symmetrical eight-figure shape.
