Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a harvesting / transporting zone for pulling out agricultural products such as root vegetables vegetated in a field and transporting them toward the rear of the machine, and a scraping / scraping device on the front side thereof. Agricultural product harvester to be equipped.

[0002]

2. Description of the Related Art Conventionally, an agricultural product, such as carrot, vegetated in a field is squeezed by a traveling machine, and its stems and leaves are sandwiched by a pair of left and right endless belts, and the rhizome is extracted from the field while the machine is traveling. Then, a harvesting / conveying zone is provided to convey the harvested agricultural products while hoisting the foliage portion toward the rear of the machine, and the foliage portion is scraped up and scraped in front of the harvesting / conveying zone. The applicant of the present invention has proposed an agricultural product harvester provided with a scraping / scraping device.
Then, the scraping / scraping device is rotated laterally to lie down due to the progress of the machine body and also to cause the intersecting foliage portions to scrape to the harvesting / transporting belt side.

[0003]

In the conventional agricultural product harvesting machine as described above, the scraping / scraping device is rotated and caused laterally with respect to the foliage, and only scrapes backward. When harvesting two-row or multiple-row root vegetables, if the stems and leaves are overgrown and are lying or entangled, harvesting and transport of the stems and leaves without sufficient scraping and scraping. There was a problem that the supply to the belt could not be performed satisfactorily. The present invention has been made for the purpose of solving the above problems.

[0004]

In order to achieve the above-mentioned object, the present invention provides a traveling machine body in which a foliage portion of an agricultural product vegetated in a field is sandwiched by a pair of left and right endless belts, and the machine body travels while the machine body travels. The roots are pulled out from the plant to harvest, and a harvesting / transportation zone is provided to transport the harvested agricultural products while hoisting the stems and leaves toward the rear of the machine.
In a harvester equipped with a scraping / plucking device for scraping and scraping the foliage on the front side of the conveyor belt, the scraping / plucking device is a vertical scraper that rotates in the longitudinal direction with respect to the foliage. It is characterized in that a lifting / scraping device and a laterally scraping / scraping device that rotates in the lateral direction are arranged side by side in the front-rear direction.

[0005]

With the above construction, the agricultural product harvester of the present invention is
The scraping / scraping device was installed on the foliage part in parallel with the vertical scraping / scraping device that rotates in the vertical direction and the horizontal scraping / scraping device that rotates in the horizontal direction. Even the foliage part that has fallen over or is entangled is scraped from the vertical and horizontal directions and also scraped and supplied to the harvesting / transporting zone.

The foliage processing apparatus 10 is composed of a pair of cutting and positioning rolls 23, 23 that both rotate inward, and a disc-shaped cutter blade 24. The foliage portion S is sandwiched by pull-out conveyor belts 6, 6. The foliage portion S and the carrot C that are conveyed are cut and positioned by the cutting positioning rolls 23 and 23.
Is positioned, and the foliage S is cut from a predetermined position by the cutter blade 24. In addition, the carrot C that is conveyed while the foliage portion S is sandwiched by the pull-out conveyance belts 6 and 6 is automatically introduced into the foliage treatment device 10 during its movement process. 10
A pair of left and right guide bodies 22 is provided on the front side of the cutting positioning rolls 23, 23. And the guide plates 22, 2
Depending on the size and shape of the ginseng C passing between the two, the passage (interval) is elastically held in a stretchable manner. In addition, the cutting height of the foliage S cut from carrot C can be adjusted, and by this adjustment, in addition to carrot, the type of root vegetables, regional characteristics,
It can be cut to a desired cutting height according to the marketability. A pair of foliage discharge rolls 25 are provided at the transport end portions of the pull-out transport belts 6, 6.

Agricultural product (carrot) harvesting machine 1 having such a configuration
First, the pull-out conveyor belts 6, 6 are adjusted up and down by the up-down adjustment handle 16a to change the height of the grounding wheel 16 in accordance with the cropping system, and also supported at an appropriate position by a hydraulic cylinder (not shown). In this embodiment, two rows of ginseng C vegetated in the field are harvested at the same time. Then, the pull-out conveyance belts 6, 6,
Digging blade 8, scraping wheels 9, 9, lateral scraping / scraping device 19 and vertical scraping / scraping device 20
The operator operates the control seat 21b while driving the
Sit down and operate the control unit 21, and the machine body performs the harvesting work while traveling by the crawlers 2 and 2.

The rows of ginseng C vegetated in the field are supported by adjusting the lower portions of the two rows by the support wheels 8b.
The excavating blade 8 that is being vibrated by the vibrating crank 18.
And the horizontal blade 8a is dug up, and the foliage portion S is first scraped by the vertical scraping and scraping device 20 and then by the horizontal scraping.
It is scraped up by the scraping device 19, is scraped, and is scraped backward by the scraping wheels 9, 9. Stem and leaf S of carrot C scraped by scraping wheel 9,9
Is sandwiched between the starting ends of the pull-out transport belts 6 and 6, and the carrot C is gently pulled out from the field as the machine progresses and lifted toward the rear of the machine. Then, the carrot C is sent to the cutting positioning rolls 23 by the guide 22. In the carrot C passing between the guide plates 23, 23, the guide plates 23, 23 expand and contract according to their size and shape, and are reliably held and positioned. In this state, the foliage S is cut at a predetermined position by the cutter blade 24, and the carrot C falls on the sorting conveyor 11. The foliage portion S remaining on the pull-out conveyance belts 6 and 6 is further conveyed to the foliage discharge roll 25.
Is discharged to the field behind the machine.

The carrot C dropped on the sorting conveyor 11 is
While being transported in the lateral direction, contaminants are sorted and removed by a sorting operator sitting on the sorting seat 11b and a sorting operator riding on the rear part of the machine body, or a rearward facing operator,
The remaining carrot C is stored in the container 13 from the transport end. If the sorting work by the operator is delayed or the container 13 is full in the sorting conveyor 11 during such harvesting work, the sorting conveyor 11 is driven without stopping the traveling of the traveling body and the driving of the harvesting unit. After shutting off only the power by the clutch lever 12 and performing the stagnant sorting process, or after replacing the container 13,
The clutch lever 12 is connected to drive the selection conveyor 11 to continue the harvesting work. Also, the sorting conveyor 11
The carrot C discharged from the transporting end portion is stored in the container 13 while being sequentially rotated by the bullet holding mechanism 14 so that the carrot C can be stored without being scratched, cracked, or damaged.

[0015]

As described above, according to the agricultural product harvesting machine of the present invention, the scraping / scraping device has a vertical scraping / scraping device that rotates in a vertical direction with respect to the foliage part, and a horizontal direction. Since a horizontal scraping / scraping device that rotates in parallel is installed in front of and behind, even when the foliage is prosperous and falls or is entangled, it can be scraped from the vertical and horizontal directions and scratched again. It can be processed in a complicated manner. Then, the stems and leaves can be reliably sent to the left and right starting ends of the harvesting / transporting zone and smoothly scraped to improve the extraction performance of the rhizomes, and can be transported backward in a predetermined posture.
