Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester for bulb crops such as onions, garlic, ginger, lilies and the like, or root crops such as carrots, radish, burdock, etc., which are mainly employed in onion harvesters. is there.

[0002]

2. Description of the Related Art Conventionally, an onion harvesting machine for harvesting onions grown on ridges is disclosed in Japanese Patent Application Laid-Open No. 9-84427. This type of onion harvester digs up a crop with a digging tool provided at the front of the fuselage while advancing the fuselage forward along a ridge, and holds the foliage of the digged onion with a pulling and conveying device. And conveyed rearward and upward, and conveyed rearward by pinching the foliage portion lower than the holding portion by the pull-out conveyance device by the positioning conveyance device,
During the transport, the foliage is cut by a cutter between the clamping portion of the pull-out transport device and the clamping portion of the positioning transport device, and then, the onion on which the foliage is cut to a predetermined length is placed on a ridge. It is something to go.

When one or two rows of onions are grown in rows on a ridge, the onion harvester is driven one way along the ridges to perform the above-mentioned excavation and foliage cutting processing. However, when harvesting onions grown in rows with four rows of onions, the onion harvester is made to reciprocate on one ridge, and on the outward path, the two onions on one side in the left and right direction of the ridges Excavation and foliage cutting processing is performed, and on the return path, excavation and foliage cutting processing of the other two onions can be performed.

[0004]

In the above-mentioned conventional apparatus, onions dropped on a ridge during transportation or onions placed on a ridge after cutting processing roll on the ridge. The onions may fall into the furrow grooves, and if the onions roll down into the furrow grooves, the onions may be crushed by the wheels of the harvester rolling in the furrow grooves, causing losses and affecting work. Also, if the onion harvester is stopped and the onions are picked up so that the onions are not crushed by the wheels, the operation is troublesome and the work efficiency is reduced.

[0005] In particular, when harvesting four rows of onions grown in rows, the onions dropped on the ridge in the middle of transportation or were placed on the ridge after the cutting process was completed. The onion etc. may roll to the center of the ridge, or to the side where the excavation and foliage cutting processing has not been performed yet, and the onion is used for excavation and foliage cutting processing in the return path. May hinder work.

Therefore, on the left and right sides of the body of the onion harvesting machine (on both the left and right sides of the strip for excavation and foliage cutting processing), the digged crop is placed on the outside of the body in the left and right direction. It has been considered to provide a regulating member made of a rubber plate so as not to roll. However, in onions grown in ridges, there are cases where the foliage is withered or short, etc. If there is a gap between the digging tool and the regulating member, the onion passes through the gap and rolls down into the groove between the ridges, or rolls to those who have not yet excavated and cut foliage The problem arises.

Further, the ridge has a ridge higher or lower than a standard height. In the case of a high ridge, a large gap is formed between the regulating member 100 and the upper surface of the ridge A as shown in FIG. , The onion B falls down from the gap into the groove between the ridges,
A problem arises in that it rolls in the direction where the excavation and foliage cutting processing has not been performed yet. In the case of a low ridge, FIG.
As shown in the figure, the lower end side of the regulating member 100 comes into contact with the ridge A and is deformed into a curved shape. In the regulating member 100 closer to the groove between the ridges, it is pushed by the onion B and escapes in the arrow J direction. The onion B may fall into the furrow groove. Further, in the regulating member 100 on the central portion side of the ridge A, a groove 101 is formed on the ridge A at a curved deformation portion on the lower end side of the regulating member 100, and the onion B may fall down into the groove 101. If the onion B falls down into the groove 101, it will not only hinder the work on the return path, but also hinder the worker from walking in the center of the ridge A after excavation and foliage cutting processing.

Accordingly, an object of the present invention is to solve the above-mentioned problems.

[0009]

The technical means taken by the present invention to achieve the above object is to excavate crops by using a digging tool provided at the front of the fuselage while moving the fuselage forward. In the crop harvester configured as described above, a regulating member that regulates the excavated crop from rolling outward in the left-right direction of the fuselage is provided behind the excavator, and the excavated crop is mounted on the harvester. The front part of the regulating member is brought close to the excavating tool so as to restrict passage between the front end of the regulating member and the excavating tool.

Further, in a crop harvester configured to dig up a crop by a digging tool provided at a front portion of the fuselage while advancing the fuselage forward, a digging tool is provided behind the digging tool. And a height regulating means for regulating the vertical position of the regulating member.

As shown in the figure, the belt is provided with a pair of left and right transport belts 46L and 46R each composed of an endless belt, and is arranged so as to extend in a substantially horizontal direction from the inherited portion at the front to the rear in the transport direction and is pulled out. The transfer start part of the positioning transfer device 7 is arranged close to the drawing start part of the transfer device 6.

As shown in FIG. 7, each of the pair of left and right conveyor belts 46L, 46R has a drive pulley 47L, 47R and a driven pulley 4 rotatable about a vertical axis.
8L, 38R, tension pulleys 49L, 49R and guide pulleys 50L, 50R are wrapped around in a direction Q shown in FIG.
47R is driven to rotate in the direction of arrow Q in FIG.
The crop B can be transported backward, and the foliage B1 can be cut by the cutting device 8 while leaving the predetermined length during the transfer.

That is, in the above-mentioned structure, the foliage section B1 which is extended substantially linearly by the raking device 5 is sandwiched by the left and right transport belts 44L and 44R of the pull-out transport device 6 and transported rearward. At this time, the belts 44L, 4
Since 4R has a backward ascending slope, crop B of two rows is ridge A
It is gradually pulled out from. And after the start of withdrawal,
By the left and right transport belts 46L and 46R of the positioning transport device 7, the foliage B1 is clamped at a position lower than the portion sandwiched by the pull-out transport device 6, and is transported rearward.

At this time, the crop B is lifted by the left and right transport belts 44L and 44R of the pull-out transport device 6, and the bulbs (roots if root crops) B2 are moved to the left and right transport belts 46.
When the lower surface side of L, 46R comes into contact, the bulb portion B2 is positioned while being restricted from rising with respect to the positioning and transporting device 7,
After the rising of the bulb portion B2 is regulated, a slip occurs in the portion where the foliage B1 is sandwiched by the pulling and conveying device 6, and the crop B is positioned at a substantially constant height from the upper surface of the ridge A and moves with the pulling and conveying device 6. It is configured to be conveyed rearward with the foliage B1 stretched between the positioning and conveyance device 7.

The transport belts 44L and 44R of the pull-out transport device 6 for holding the upper part of the foliage B1 and the foliage B1
Conveyor belt 46 of the positioning conveyor 7 for holding the stock
The foliage B1 is stretched over L and 46R, and the foliage B1 is cut by the cutting device 8 disposed in the both ends (triangular space) S of the both. The bulb part B2 is conveyed backward with the root of B1 being clamped, while the upper part of the cut foliage part B1 is released to the right by the leaf releasing rotating body 45. .

The leaves of the left and right conveyor belts 46L and 46R of the positioning conveyor 7 have a predetermined interval at the start end and a close contact at the end (or a narrower interval than the start end). Left and right transport belts 46L, 4
The interval of the start end side of the foliage holding portion of 6R is larger than the end side. Also, the left and right transport belts 46L, 46R
The middle part of the foliage holding part of the guide pulley 50
L, 50R, which are closely attached to the front side of the foliage cutting position by the cutting device 8 (or have a smaller interval than the starting end side), and the opposing interval C of the left and right transport belts 46L, 46R is shifted from the starting end to the cutting position. It is gradually narrowed toward the end, and has a close shape (or a state with a slight gap) from the cutting position of the foliage toward the end.

Therefore, the left and right transport belts 46L, 46L
Until the rising of the bulb portion B2 is restricted from the beginning of the foliage holding portion of R, the gripping force of the foliage B1 by the conveyor belts 46L and 46R is weak, and from the foliage cutting position to the end,
The holding force is strong. The reason for this is that
During the process of nipping the foliage B1 and transporting it rearward by the positioning and transporting device 7, the bulb B2 is transported by the transport belts 46L and 46L.
Until the rise is regulated by contact with R, bulb portion B1
In order to allow the ascent of the leaves, a slip must occur between the conveyor belts 46L and 46R and the foliage B1.
This is because, after cutting 1, the stem of the foliage B1 must be securely clamped so that the bulb B2 does not fall.

The positioning / conveying device 7 does not have to be horizontal in the rearward direction, but rather has a more sloping rearward inclination than the pull-out / conveying device 6 (inclined so as to move upward as it goes rearward). It may be. Further, the pinching force of the foliage B1 by the transport belts 46L and 46R may be weak until the bulb B2 is controlled to rise with respect to the positioning transport device 7, and may be strong after the foliage cutting position.

In the illustrated example, the positioning / conveying device 7 is constituted by a single belt conveyor having a pair of right and left conveying belts. However, the present invention is not limited to this. And a belt conveyor on the front side for nipping and transporting the foliage B1 and the bulb B2 until the lifting of the foliage 7 is restricted (or to a position just before the foliage cutting position).
After the rise control, the foliage B1 is inherited from the front belt conveyor, and the foliage B1 is pinched and conveyed to the aligning and discharging device 9 through the cutting device 8 and positioned on the two belt conveyors with the rear belt conveyor. The transport device 7 may be configured.

The transport belts 46L, 46R are crop B
In order to reduce the pain at the neck contact portion of the bulb portion B2 since the stem of the foliage portion B1 is sandwiched, it is preferable that a sponge belt or the like is overlaid on the outer peripheral surface of the endless rubber belt. Note that the transport speed of the pull-out transport device 6 is faster than the transport speed of the positioning transport device 7 so that the vertical orientation of the crop B is constant (or not greatly inclined).
Has become.
