Mechanically harvesting device of three-leafy vegetables

Abstract

The invention relates to vegetable harvesting machinery, in particular to a mechanically harvesting device of three-leafy vegetables. The device comprises a motor, a rack, a gear box, a fan, an air pipe, cutters, a truck and a collecting box and is characterized by adopting a motor power source to harvest and collect the three-leafy vegetables in a greenhouse and adopting an eccentric roller type crane block transmission mechanism and a simple height-adjustable shaft sleeve to harvest, thereby being suitable for the higher and higher growth characteristic of a multi-season crop such as the three-leafy vegetables, and moreover, the collecting device is integrated into a whole, thereby the operations of harvesting and collecting can be completed by a single operator. The device has the advantages of high working efficiency, compact mechanism, good machine flexibility and no pollution, is convenient to operate, and can be used for improving the quality of re-grown three-leafy vegetables.

Description

technical field [0001] The invention relates to a vegetable harvesting machine, in particular to a three-leaf vegetable mechanical harvesting device. Background technique [0002] The market demand for clover, a characteristic vegetable in southern my country, is increasing, and the planting area is further expanded. In addition, the south implements a joint production contract responsibility system that divides fields to households. Some fields are not suitable for maneuvering due to their small size, irregular shape, and poor flatness. Type harvesting machinery can only be harvested manually with a sickle, resulting in shallow stubble, which is not conducive to the secondary growth of shamrocks. For manual operations, the labor intensity is high and the efficiency is low. There is no harvester suitable for harvesting shamrocks on the market. mechanical. [0003] At present, the harvesting principle of some forage harvesters on the market is similar to that of clover harvest...

AI Technical Summary

Problems solved by technology

1. According to its cutting device, it can be divided into two types: blade reciprocating motion and disc rotary motion; disc rotary harvesting device is easy to cut crops during high-speed cutting, and is only suitable for harvesting pasture crops. The movement frequency is low, it is easy to get stuck and blocked, and it is difficult to adapt to the cutting of flexible stems; 2. Some pasture harvesters on the market use gasoline engines to drive the entire mechanism to operate, and the fuel consumption cost is more than 100 yuan a day, and the ratio of gasoline and engine oil is difficult to master , Especially in summer high-temperature easy-to-pull cylinders, the gasoline volatile oil in the mixed oil precipitates and sticks to the oil circuit, and maintenance work must be carried out every time it is used up, and the accessories are expensive and energy-consuming, and the three-leaf vegetables are grown in greenhouses. Gasoline "runs, runs, drips, leaks" and pollutes the environment; 3. The height of the cutting knife of the current pasture harvesting device cannot be adjusted, and is limited to a fixed height. For clover, which grows ten seasons a year, it continues to grow after cutting And there are certain limitations when cutting crops with higher and higher heights; 4. Generally, there are many forage harvesting machinery operators
