Curved-surface toothless fruit picking mechanism

Abstract

A curved-surface toothless fruit picking mechanism comprises an auger shaft, spiral stirring rods and auger coupling rods, wherein the auger coupling rods are distributed at two ends of the auger shaft, the spiral stirring rods are fixedly connected with the auger shaft through the auger coupling rods, the number of the auger coupling rods is even, and the auger coupling rods are evenly distributed along the center of the auger shaft in a central symmetry mode; and the number of the spiral stirring rods is even, and the auger coupling rods at two ends of each group of the spiral stirring rods are evenly distributed along the center of the auger shaft in a central symmetry mode. Each group of spiral stirring rods comprises two spiral stirring rods with an auger plate between. Preferably, the number of the auger coupling rods is four and two auger coupling rods are arranged at each end of the auger shaft. According to the curved-surface toothless fruit picking mechanism, the spiral stirring rods are used for replacing tooth-shaped structures, breakage of peanuts and smashing of peanut seedlings caused in a fruit picking process through the tooth-shaped structures are avoided, the fruit damage rate is reduced, blocking of equipment due to fruit fragments and seedling fragments is avoided, and equipment maintenance costs are reduced.

Description

technical field [0001] The invention relates to a fruit-picking mechanism for peanut harvesting machines, in particular to a toothless curved-surface fruit-picking mechanism, which is especially suitable for separating various dry and wet peanut pods and peanut vines. Background technique [0002] Peanuts, also known as groundnuts, are known as "vegetable meat". The oil content is as high as 50%, the quality is good, and the smell is fragrant. In addition to being edible, peanuts are also used in printing and dyeing and papermaking industries; peanuts are also a traditional Chinese medicine, suitable for symptoms such as malnutrition, spleen and stomach disorders, cough, phlegm and asthma, and lack of milk. As an important economic crop, peanut has a wide planting area in my country. Therefore, the harvesting method of peanuts is of great significance to the economic development of the growing area. The peanut picking device is the core component of the peanut harvester. ...

This method of fruit picking has the disadvantages of dirty fruit picking, unclear separation, and high harvest loss

[0004] Generally speaking, most of the fruit picking devices used in the existing peanut harvesting machines are traditional toothed fruit picking devices. This kind of device picks the fruit by combing and hitting the peanut plant through a toothed structure, which often easily leads to broken peanuts. The crushing of peanut vines and peanut vines makes it difficult to separate peanuts from peanut vines; this situation is more obvious when picking fresh and wet peanuts, so the damage rate is higher, which affects the development of peanut industry
