Connecting-rod stretchable-cuttage pull-type perforating machine for stevia rebaudiana seedlings

Abstract

The invention discloses a connecting-rod stretchable-cuttage pull-type perforating machine for stevia rebaudiana seedlings. The perforating machine includes a rack, a double-shaft output-type gearboxand a perforating machine body are erected on the rack, the perforating machine body includes an upper pressing plate and a lower pressing plate, the upper pressing plate and the lower pressing plateare connected through screw rods, the lower end surface of the upper pressing plate is provided with perforating heads, holes corresponding to the perforating heads are distributed in the lower pressing plate, the perforating machine body is in transmission connection with the gearbox through a transmission mechanism, the transmission mechanism includes roller shafts in transmission connection with the two ends of an output rotating shaft of the gearbox, the roller shafts are welded to two eccentric wheels and positioned at the corresponding sides of the eccentric wheels respectively, the other end of each eccentric wheel is rotatably connected with a connecting rod, the other end of each connecting rod is fixedly connected with a transition connecting rod, the other end of each transitionconnecting rod is in bearing connection with an execution rod, and the other end of each execution rod is welded to a padding plate on the upper pressing plate. By adopting the connecting-rod stretchable-cuttage pull-type perforating machine for the stevia rebaudiana seedlings, a blank space in the current market of stevia rebaudiana perforating machines can be effectively filled up, labor forceis liberated, the planting scale of stevia rebaudiana is expanded, and the cost is reduced.

Description

Technical field: [0001] The invention relates to a punching machine, in particular to a traction type punching machine for telescopic cutting of stevia seedlings with connecting rods. Background technique: [0002] Stevia is also known as sweet tea. The sugar content of stevia is quite rich. The glycoside extracted from stevia is 300 times sweeter than ordinary sugar, and the calorie of stevia is low, about 3% of the calories of sucrose. One, it will not make people gain weight, especially suitable for diabetic patients and obese patients. Stevia can not only be used for daily drinking and the preparation of fruit drinks, but also has a very high medicinal value. Long-term use of stevia to boil water can also reduce blood pressure, promote metabolism and strengthen the body. Stevia is known as the third largest source of healthy sugar in the world due to its high sweetness, low calorie, pure natural and pollution-free characteristics, and has a very broad market prospect. ...

AI Technical Summary

Problems solved by technology

[0003] The stevia planting process is divided into seedling raising, planting management, harvesting and circle planting. The breeding process mostly uses methods such as sowing, cutting, layering, and branching. In the current cutting and punching process, manual operations are mostly used and supplemented by simple methods. The tool is not only labor-intensive but also inefficient, which increases the planting cost of stevia, and can only be planted on a small scale. Because it is manual labor, the standardization of punching cannot be guaranteed, which will affect the subsequent planting of stevia and cannot be formed. Intensive seedling cultivation, so the traditional method of stevia cuttings and punching can no longer meet the needs of the market
