SOLUTION: This harvester has a carrier (21) functioning to nip the stem/leaf portion (13b) of an underground crop (13) and pull the crop off the ground and carry it backward; wherein an element (26) for clearing away the muddy soil adhered to such a crop (13) is furnished on the carriage path (14) of the carrier (21).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a harvester for harvesting underground crops such as onions.

[0002]

Conventionally, in a machine for harvesting underground crops such as onions, means for cutting and removing foliage during harvesting and transporting of crops by a carrier so as to harvest only the crop body. However, the mud attached to the crop body and the root of the crop have been troublesome to perform proper treatment after harvesting.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a soil harvester having a carrier for holding the foliage of an underground crop, pulling it out of the ground, and transporting the crop backward. Place the dropped body on the transport path of the transport body,
The present invention enables a harvesting operation which does not require removal of mud from crops after harvesting and has a high work efficiency.

In addition, a root cutting body for cutting the root of the crop is provided on the transport path of the carrier to enable a harvesting operation with good work efficiency without cutting the root of the crop after harvesting. .

And a pair of left and right endless main body conveying belts (21), which are conveying bodies for holding and rearranging the base end of the main body and conveying the rearward of the machine body, and the pulling and conveying belts (18) and (21). (18) A disk-type cutting blade (22) for cutting and separating the foliage (13b) and the ball (13a) of the onion (13) pinched and conveyed in (21), and a rear end of the left pulling belt (18). A foliage release star wheel (23), which is disposed below and discharges the cut foliage (13b) after cutting to the left side of the machine, and a rotating shaft (24) is disposed substantially parallel below the main body transport belt (21). The transport belt (2) is formed by a linear body (25) made of a flexible resin or the like formed radially on the outer peripheral surface of the rotating shaft (24).
A drop body (26) for separating and removing mud adhering to the bottom of the ball portion (13a) pinched and transported in 1), and a drop body (2)
6) A root cutting blade (27) which is a disk blade root cutting body which cuts a bead root (13c) below a ball portion (13a) conveyed by a conveying belt (21) which is disposed at a rear position of (27). The ball (13a), which has been disposed below the rear end of the conveyor belt (21) and has been soiled and has been subjected to the root cutting process, is disposed at the rear of the work table (1).
2) A harvesting work unit (2) including a charging chute (29) guided into the upper container (28) and a gauge wheel (30) mounted on the left outside of the left raising case (19) so as to be adjustable in support height. Is composed.

[0007] As shown in FIG. 4 and FIG.
6) The ball portion (13a) is obtained by bringing the top of the rotation circular locus of the wire (25) close to the bottom of the ball portion (13a) of the onion (13) conveyed by the conveyor belt (21). Mud adhering to the beard root (13c) is scraped off by the rotation of the linear body (25), and as shown in FIG.
The brush (25a) may be implanted on the outer peripheral surface of
In addition, the wire (25) and the brush (25a) have appropriate flexibility, and even when the wire (25) comes into contact with the ball (13a),
a) is configured not to be damaged.

Then, the rotating shaft (34) is linked to the output of the engine (3) via sprockets (35) and (36) and a chain (37) and the like, so that the onion (13) serving as the base end of the beard root (13c) is formed. The root cutting blade (27) has a width equal to or greater than the size (diameter) of the root portion (13d), and the onion (3) is moved by the transport belt (21) with respect to the onion (3).
The root cutting blade (27) is moved upward about 1) to move the root (13).
When the circumferential cutting edge (27a) of the root cutting blade (27) is brought into contact with d), the beard root (13c) is cut.

The root cutting blade (27) detects the moving position of the ball portion (13a) of the onion (13) by a position sensor (38) and automatically moves up and down by a lifting mechanism (39) such as a solenoid. To cut the beard root (13c), or to swing the root cutting blade (27) horizontally in the left and right direction while maintaining the same height, or to adjust the height according to the size of the ball portion (13a). Any configuration may be used, such as a stationary position.

As described above, the dropper (26) is disposed substantially parallel to the transport path (40) of the transport belt (21), and the leek (13) is held and transported by the pull-out belt (18). Inside, the onion (13) is pulled out from the ridge (M) which is underground, and is transferred to the conveying belt (21) on the way and conveyed by clamping the foliage (13b) between these belts (18) and (21). During the cutting, the foliage (13b) is cut by the cutting blade (22), and the onion (13a) of the onion (13) is automatically conveyed while being held by the conveyor belt (21). The removal of the mud adhering to the bottom of 13) is performed, so that the removal of the soil after harvesting becomes unnecessary, and the efficiency of the operation can be improved.

In addition, the beard root (13c) of the onion (13) is also cut by a root cutting blade (27) provided behind the soil drop body (26) on the transport path (40), and the transport path (40) From the end of the container, the onion (13) that does not require post-treatment such as mud removal and root cutting is stored in the container (28), and the working efficiency can be greatly improved.

[0012]

As is apparent from the above embodiments, the present invention provides a harvesting machine having a carrier (21) for holding a foliage (13b) of an underground crop (13), pulling it out of the ground and transporting it backward. In, the shovel (26) for removing mud adhering to the crop (13) is transported along the transport path (4) of the transporter (21).
0) Since it is provided above, it is possible to perform a harvesting operation with good work efficiency without having to remove mud from the post-harvest crop (13).

The root cuttings (27) for cutting the roots (13d) of the crop (13) are transported to the transport path (4) of the transporter (21).
0) Since it is provided above, it is possible to perform a harvesting operation with good work efficiency without cutting the root (13d) of the post-harvest crop (13).
