Traditional chinese medicine experimental plot plants harvesting apparatus
Technical Field
The invention discloses a planting and harvesting device for a traditional Chinese medicine experimental field, relates to a protective device which is used for assisting the existing scissors to clamp and prevent silybum marianum from splashing in a shearing process when a new variety of silybum marianum is subjected to experimental planting and harvesting, and belongs to the field of traditional Chinese medicine preparation. In particular to a device for clamping and preventing silybum marianum from splashing by firstly clamping and fixing the neck part through a protective plate and then cutting off twice through scissors when silybum marianum is harvested.
Background
At present, the fruit order extract of the silybum marianum can be used for treating liver diseases, splenopathy gallstones and chronic cough, clearing heat and removing toxicity, protecting the liver, and having good treatment effect on acute or chronic liver diseases, can quickly improve subjective symptoms and certain biochemical indexes of patients with liver diseases such as serum bilirubin, glutamic pyruvic transaminase and the like, the silybum marianum is a biennial herb, has an upright stem and a height of 30-200 cm, is multi-branched, smooth or spidromous hair, is provided with a longitudinal ridge groove, has a head-shaped inflorescence diameter of 3-6 cm, is provided with a single branch top, is wide and spherical in a general bud, is provided with a long spine at the top end, needs to pay attention to various performances of a new product during experimental planting of the new product in a small range, comprises the influence on the drug effect of the new product caused by a harvesting mode, is mostly harvested by a machine for mature variety planted in a large area, has large damage to the fruit order of the silybum marianum during the mechanical harvesting process, then the silybum marianum is conveyed into a material box through a belt, in the whole process, the silybum marianum completely falls off, the harvesting rate is low, the fruit can not be harvested independently, further researching the medicine composition of the infructescence, and the medicine effect is not clear and is easy to influence in the experimental stage of new product planting, therefore, for the experimental planting with small area, manual harvesting is mostly adopted, the infructescence is cut by scissors, however, in the cutting process, the fruit can easily splash and fall on the ground when being cut, the fruit can not be collected completely, the fruit can be grasped by one hand, the harvesting scissors can be operated by one hand, but meet some stems comparatively thick and difficult results, need both hands application of force, consequently inefficiency often needs two people to cooperate to accomplish, and the infructescence harvest ratio of silybum marianum is low, splashes everywhere, and the manual work needs the step of picking up in the input energy, and at the in-process that splashes, and the damage to the preface is very serious.
Publication number CN201303515 the utility model belongs to scissors, in particular to a fruit and vegetable harvesting scissors. The hand guard 5 is connected with the handle 10 through screws, the handle 10 is provided with the salient points 4 near the scissor head, two ends of the spring 9 are connected with the salient points 4 respectively, the knife edge 1 of the scissor head 2 is of an arc structure, the tail end of one side of the handle 10 is provided with a fixing belt, the corresponding position of the handle 10 on the other side is provided with a fixing belt hanging buckle 7, the device needs to catch fruits by hands or another person when cutting, and then the fruits are trimmed, so that the efficiency is low, and the manpower is wasted.
