DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for preventing sediment from adhering to a rod conveyor device used in a root crop harvester such as a beet harvester.

[0002]

2. Description of the Related Art A root conveyer such as a beet harvester is connected to a towing vehicle such as a tractor, so as to dig up root crops while traveling in a root crop field, and to provide a rod conveyer for digging and raising root crops below the harvester. , And are transported diagonally upward, and loaded into a hopper on a harvester via a horizontal conveyor, a lifter, or the like.

Since root vegetables excavated from soil need to separate the soil and root stems (hereinafter referred to as soil and the like) of the root vegetables adhered to the surface, the conveyer device has a rod-like conveyer device for separating the soil and the like. Is used, and soil and the like fall down while the root vegetables are being conveyed on the rod conveyor.

[0004]

This rod conveyor device has a structure in which an endless rod conveyor is suspended over a rotary drive pulley, a driven pulley, and a tension pulley provided on the left and right frames. They are connected by a bar-shaped connecting member suspended in the lateral direction. Since the connecting member is provided with the transport rotation side line and the return rotation side line of the rod conveyor, the soil and the like separated from the root vegetables being transported are pulled to the connecting member while falling from the rod conveyor. Hangs and sticks.

[0005] The soil and the like adhered in this manner gradually grows into large lumps, which are clogged between the transport side and the return side line of the rod conveyor, impeding the smooth operation of the rod conveyor and removing it. It took a lot of effort and time.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a rod conveyor device for a root crop harvesting machine to which soil and sand are less likely to adhere, and in particular, to provide a mechanism for preventing earth and sand from attaching to a frame connecting member.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an endless rod conveyer which is hung on a rotary engaging member of left and right frames connected by a rod-like connecting member, and removes root vegetables dug out of soil. In the earth and sand adhesion preventing mechanism of a root conveyor harvester rod conveyor frame to be carried on a rod conveyor, a plurality of ring-shaped or sleeve-shaped cover members are rotatably loosely fitted in the longitudinal direction of the rod-shaped coupling member. I do.

[0008] The cover member loosely fitted to the connecting member is preferably provided so as to move in contact with the rod conveyor on the return rotation side of the endless rod conveyor.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view showing the entire configuration of a root vegetable harvesting machine 1 such as a beet harvester. In this root vegetable harvesting machine 1, a hopper 4 is placed on a chassis 3 having wheels 2, and a towing arm 5 in front of the vehicle body is connected to a rear part of a tractor. Connected to the three-point link (not shown) of the
It is configured to be pulled in a direction.

As shown in FIGS. 1 to 3, a conveyor frame 7 having an endless rod conveyor 6 rotatably suspended therefrom is provided below the chassis 3 at an upward slope toward the rear. An excavator member 8 for excavating a beat is fixed to the tip of the bottom 7 so that the tip of the excavator 8 faces downward in the traveling direction.

Above the rod conveyor 6, an endless belt conveyor 9 made of a soft material such as rubber is provided.
The rod conveyor 6 is rotatably mounted at a predetermined interval between the rod conveyor 6 and the lifting side 6a. In addition, the member shown by the code | symbol 10 in FIG. 1 cut | disconnects the residue scattered in the area by the rotatable vertical blade 10 ', prevents adhesion to the surrounding frame, and cuts the soil beside the root vegetables. A digging coulter for facilitating digging by the shovel member 8.

Thus, as the root crop harvester 1 travels,
The root vegetables dug and raised by the shovel member 8 are transferred to the lifting side 6a of the rod conveyor 6, and are lifted by the rod conveyor 6 to the rear of the chassis 3 while being lightly supported by the belt conveyor 9 above. The hopper 4 is put into the hopper 4 via the lifter 11 and the like.

The endless rod conveyor 6 is composed of a rotating pulley 1 mounted on both ends of left and right conveyor frames 7 and 7.
2. Guide pulley 1 mounted on the middle of the conveyor frame 7
3. It is rotatably engaged with the tension pulley 14. The left and right conveyor frames 7, 7 on which the endless rod conveyor 6 is installed are connected by a rod-shaped connecting member 15, and in the present invention, a plurality of cover members 16 are rotatably loosely fitted on the shaft of the connecting member 15. Yes, rod conveyor 6
The dirt and foliage dropped from the cover member 16 are scattered around by the rotation or vibration of the cover member 16 so as not to adhere to the fixed connecting member 15 itself.

The cover member 16 may be a ring or a sleeve, but it is preferable that a plurality of cover members 16 are provided so that adjacent cover members 16 rotate independently. Also, the coupling member 1
It is desirable that the cover member 16 be loosely fitted over the entire length of the shaft body 5 so that no adhesive growth occurs on any part of the shaft body.

Preferably, the cover member 16 is disposed so as to contact the return side 6b of the rod conveyor 6. This arrangement may be adjusted at the position of the coupling member 15,
Further, the adjustment may be performed by the outer diameter of the cover member 16, or may be performed by the return track of the rod conveyor 6.

As described above, when the mudguard cover member 16 of the connecting member 15 is disposed so as to touch the return side of the rod conveyor 6, the cover member 16 is constantly rotated, vertically moved, etc. by the rod conveyor 6. Soil and leaf stems are less likely to adhere.

[0017]

According to the present invention, since the cover member is loosely fitted to the rod-like connecting member connecting the left and right frames of the rod conveyor and is rotated by the collision of a falling object, the earth and sand that has fallen from the cage-like gap of the rod conveyor can be removed. Scattered by this cover member. Therefore, it is possible to rationally solve the problem that the soil and the leaf stem attached to the connecting member are stacked and grown and hinder the smooth operation of the rod conveyor as in the related art.

When the cover member is disposed in such a position as to touch the return side of the rod conveyor, the cover member always rotates automatically or moves up, down, left and right by the rotation of the belt conveyor. Therefore, since the falling earth and sand hits the moving object, the scattering action is promoted, and the adhesion preventing effect is further improved.
