Description

Technical Field

[0001] The invention belongs to a Chinese medicinal material harvesting machine, and mainly relates to a special harvesting cutter for spike-grain Chinese medicinal materials. Background Art

[0002] Spike-grain Chinese medicinal materials are a type of Chinese medicinal crop with mature fruits or seeds growing on the top of the plant. In order to ensure its medicinal value, this type of medicinal material is mostly harvested when the fruits and seeds of the plant are fully mature or about to be fully mature. At this time, the biological structure of the fruit or seed is relatively fragile, and a slight collision can easily cause the loss of spikes and grains. Therefore, the current harvesting of the fruits or seeds of spike-grain Chinese medicinal materials is still mainly done by manual labor, and the low picking efficiency, high labor intensity, and high harvesting cost are significant and prominent technical defects. At the same time, because the fruits and seeds of spike-grain Chinese medicinal materials are very small, even if they are harvested by manual labor, there are still technical problems such as difficulty in harvesting and large losses of fruits and seeds that should be solved.

[0003] In recent years, with the rapid development of traditional Chinese medicine in my country, the planting area of ​​spike and grain Chinese medicinal materials has increased year by year. It is urgent to realize the mechanized harvesting of spike and grain Chinese medicinal materials. It is of great significance to promote the development of traditional Chinese medicine in my country, improve the quality of picking and operation efficiency, reduce losses, and avoid the waste of fruits and seeds. Summary of the invention

[0021] The following is a detailed description of the implementation scheme of the invention with reference to the accompanying drawings. A special harvesting platform for spike and grain Chinese medicinal materials, wherein side panels 1 are fixedly mounted symmetrically on the left and right sides of a bottom plate 21, a rear baffle 18 with a through hole at the center is fixedly mounted on the rear side of the bottom plate 21, a power transmission mechanism 24 connected to an external power input shaft 15 is mounted on the left side plate 1, a tubular mounting frame 22 is fixedly mounted on the front end of the bottom plate 21, and a plurality of side panels 1 are mounted on the top of the front end of the tubular mounting frame 22. A plurality of boat-shaped trough plates 5 and dividing plates 6 are fixedly installed at intervals, and the boat-shaped trough plates 5 are configured as a whole with a high front and a low rear. A reciprocating cutter assembly 3 is horizontally installed on the lower front end of the tubular mounting frame 22, and an exhaust square tube 23 with an exhaust hole 23-1 is fixedly installed at the upper corner of the front end of the tube cavity of the tubular mounting frame 22. The exhaust hole 23-1 is connected to the arc-shaped blowing hole 22-1 opened at the upper corner of the front end of the tubular mounting frame 22; at the position between the two relatively arranged side plates 1, located The upper part of the bottom plate 21 is rotatably supported and installed by the front rotating shaft 9 and the rear rotating shaft 10 arranged in parallel with each other, and the power transmission mechanism 24 is connected with the reciprocating cutter assembly 3, the rotating roller 4 and the conveying roller 20 for power transmission; the upper cover plate 11 is supported and fixed on the upper end of the rear baffle 18 and the two oppositely arranged side plates 1, and the arc-shaped mesh cover plate 7 can be pulled and moved in the front and rear directions on the upper side of the upper cover plate 11; on the right side plate 1 A right angle frame 17 with a support plate 16 is fixedly mounted on the rear portion, a motor 14 and a blower 13 are fixedly mounted on the support plate 16, an air supply square pipe 8 is horizontally mounted on the upper end of the rear baffle 18, the air inlet end and the air outlet end of the main air duct 12 are respectively connected to the blower 13 and the air supply square pipe 8, four L-shaped air supply ducts 19 are evenly distributed and mounted in the rear baffle 18 and below the bottom plate 21, and the two ends of the four L-shaped air supply ducts 19 are respectively connected to the air supply square pipe 8 and the exhaust square pipe 23. A guard plate 2 is fixedly mounted on the lower portion of the four L-shaped air supply ducts 19.

[0022] During harvesting operation, the rotating external power input shaft 15 drives the reciprocating cutter assembly 3, the roller 4, and the conveying roller 20 to move respectively through the power transmission mechanism 24. With the cooperation of the boat-shaped trough plate 5 and the grass-dividing plate 6, the reciprocating cutter assembly 3 cuts off the spike-grain Chinese medicinal stems from the ground, and the stems with medicinal fruits or seeds are quickly and smoothly moved to the rear guard plate 2 on the bottom plate 2 by the rotating roller 4 and the conveying roller 20. At the same time, the naturally fallen medicinal fruits or seeds are picked up by the front high and rear low configuration. After being received by the boat-shaped trough plate 5, it flows to the upper part of the rear bottom plate 21 by itself. The positive pressure wind force of the rotating blower 13 passes through the main air duct 12, the air supply square pipe 8, the four L-shaped air supply pipes 19, and the exhaust holes 23-1 on the exhaust square pipe 23 in sequence, and blows to the rear along the upper end surface of the bottom plate 21 through the arc-shaped blowing holes 22-1 on the tubular mounting frame 22. The wind force discharges the medicinal fruits or seeds and stems that fall from the upper end surface of the bottom plate 21 from the through hole at the center of the rear baffle 18, completing the mechanized harvesting of spike-grain Chinese medicinal materials. The arc-shaped mesh cover plate 7 can be adjusted by sliding forward and backward on the upper cover plate 11 according to the height of the spike-grain Chinese medicinal stems, changing the height position, and achieving a better collection effect on the fallen spike-grain Chinese medicinal fruits or seeds.
