Description

Technical Field

[0001] The invention belongs to the technical field of Chinese medicinal material harvesting machinery of agricultural machinery, and specifically relates to a front-mounted ophiopogon japonicus combine harvester. Background Art

[0002] Ophiopogon japonicus is a precious Chinese herbal medicine of rhizome type, mainly distributed in Mianyang, Sichuan, Cixi, Zhejiang and other places. Ophiopogon japonicus is a small root tuber that swells into an oval or spindle shape in the middle or near the end of the root. The two ends of the small root tuber are 10~15mm long, the middle diameter is 5~10mm, and it is light brown-yellow. The underground roots of Ophiopogon japonicus plants are slender and 1~2mm in diameter; the stems of the plants are very short, growing from the base of the leaves, grass-like, 100-400mm long, a few are longer, 1.5-3.5mm wide, with 3-7 veins, and fine serrations on the edges.

[0003] When harvesting Ophiopogon japonicus, the whole plant is dug out of the soil, and the small tubers in the underground part are used as the main medicinal part. The clustered stems and leaves in the aboveground part are divided into 4 to 5 plants according to the main veins and transplanted as seedlings for the next year. The common rhizome medicinal material harvesting machinery on the market is mainly suspended Chinese medicinal material harvesters, which need to be matched with power machinery such as tractors. Since the traction power machinery of the suspended Chinese medicinal material harvesting machinery is located in front of the excavation device, the tires or tracks of the power machinery will crush the stems of the Ophiopogon japonicus plants during operation, destroying the growth buds of the stems, resulting in the crushed Ophiopogon japonicus stems that cannot be planted as seedlings for the next year. Due to the limitations of space layout and structural size, the suspended Chinese medicinal material harvester directly lays the Ophiopogon japonicus on the ground after excavation, requiring manual secondary picking, low harvesting efficiency and high labor costs. Summary of the invention

[0004] In order to solve the problems of power machinery crushing Ophiopogon japonicus stems and seedlings and low efficiency of manual picking, the present invention provides a technical solution for front-mounted excavation and integrated combined harvesting of Ophiopogon japonicus, in which an excavating shovel is placed in front of the power machinery, and the width of the excavating shovel covers the outer width of the track of the power machinery, ensuring that the power machinery will not crush the Ophiopogon japonicus stems and seedlings.

[0005] The objective of the present invention is achieved in this way. A front-mounted Ophiopogon japonicus combine harvester comprises a depth limiting device, an excavating device, a primary conveying and separating device, a secondary conveying and separating device, a collecting device, a traveling device and a cab. The depth limiting device is installed at the front of the whole machine, the depth limiting device is connected to the excavating device behind, the excavating device is connected to the primary conveying and separating device behind, the primary conveying and separating device is connected to the secondary conveying and separating device behind, the secondary conveying and separating device is connected to the collecting device, the traveling device is located at the bottom of the whole machine, is connected to the primary conveying and separating device through a primary rotating support, is connected to the secondary conveying and separating device through a secondary mounting seat, is connected to the collecting device through a flip frame, is connected to the cab through a bolt connection, adopts a crawler chassis, the outermost width of the crawler chassis is not greater than the working width of the excavating device, the engine is positioned in a rearward form, and the traveling speed is adjusted by a stepless speed change.

[0006] The beneficial effects of the present invention are: (1) The excavating device is located in front of the whole machine and the working width of the excavating device is larger than the outermost width of the crawler track. During the harvesting operation of Ophiopogon japonicus, the walking device will not crush the stems of Ophiopogon japonicus, thus avoiding mechanical damage to the stems of Ophiopogon japonicus and ensuring the quality of the stems of Ophiopogon japonicus as seedlings.

[0007] (2) This front-mounted machine adopts vibration-type drag-reducing excavation, two-stage vibration separation and transportation, and a four-stage tooth roller and bar roller combined soil crushing method, which can meet the efficient root-soil separation under clay soil conditions and meet the agronomic requirements of Ophiopogon japonicus. The front-mounted Ophiopogon japonicus combine harvester can complete the functions of excavation, separation, transportation, collection and automatic unloading at one time, reducing the manual harvesting process, greatly improving the harvesting efficiency and reducing the labor cost.
