Problems solved by technology

However, whether it is a segmented peanut harvester or a peanut combine harvester, the pick-up device is a hard finger-type pick-up device. This pick-up device has the following problems: (1) The finger is a rigid material with high strength. When picking up, the impact on the material is greater, and it is easy to damage the fruits of the crops, causing unnecessary losses; (2) There are inevitably obstacles such as stones in the field, and the hard finger stick often encounters obstacles such as stones. The broken teeth will be damaged due to rigid impact, which will affect the normal operation of picking; (3) The finger bar is linear, and when the slats are thin, the crops are easy to slip off the finger bar, resulting in a high rate of missed picking

Abstract

A picking device using an elastic claw comprises a supporting plate and pointing rods fixed on the supporting plate. The pointing rods are made of an elastic material, namely elastic nylon. An included angle beta between each pointing rod and the supporting plate ranges from 20 DEG C to 35 DEG C. Each pointing rod comprises a pointing rod end portion and a pointing rod root portion which are connected integrally. The pointing rod end portions are fixed on the supporting plate through the pointing rod root portions. An included angle alpha between each pointing rod end portion and each pointing rod root portion ranges from 158 DEG C to 172 DEG C. The pointing rod end portions are in a shape of a straight line, the pointing rod root portions are arc-shaped, and the radian of the pointing rod root portions ranges from 0.7 rad to 1.1 rad. The number of groups of the pointing rods is three. Each group of pointing rods comprises two pointing rods, and the plurality of groups of the pointing rods are evenly distributed on the same plane of the supporting plate. The pointing rods are made of nylon with certain elasticity so that the picking device is appropriate in the strength and not prone to damage, avoids rigid impact on crops, guarantees completeness of fruits, and reduces troubles of device maintenance.

Description

technical field [0001] The invention relates to a pick-up device for a peanut harvester, in particular to a pick-up and delivery device with nylon elastic teeth, which is suitable for picking up dry and wet peanuts in different planting modes. 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. [0003] At present, the vast majority of peanuts are harvested manually, including pulling out the...
