Description

Backpack Peanut Picking Fruit Picking Combine Harvester

technical field

The utility model relates to a peanut combined harvester, in particular to a knapsack peanut picking combined harvester, which is suitable for combined harvesting of dry and wet peanuts in different planting modes.

Background technique

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.

At present, the vast majority of peanuts are harvested manually, including pulling out the peanuts, laying them out, drying them in the sun for a few days, and then manually picking them up on the field for fruit picking, shelling, and cleaning. Manual methods are not only labor-intensive , and the work efficiency is low, labor-intensive and time-consuming, and the production cost is extremely high. With the development of peanut harvesting machinery, there have been peanut segment harvesters and peanut combine harvesters. Peanut segmental harvesters mostly use four-wheel tractors, which can complete the operations of digging, shaking the soil, and laying peanuts, while the fruit picking and cleaning after drying are still done manually; the peanut combine harvester has the functions of digging, conveying, etc. , Separation of soil, fruit picking, separation and cleaning, and fruit collection and other compound functions are suitable for large-area plots and have the characteristics of high production efficiency and low harvest loss rate.

As a link with the largest workload in the peanut harvesting process, the picking and fruit picking device still has certain defects in the current peanut combine harvester. The existing pick-up devices are all hard finger-type pick-up devices. This pick-up device has the following problems: (1) The finger is made of rigid material with high strength. When picking up, it has a large impact on the material and is easy to damage. (2) It is inevitable that there are obstacles such as stones in the field, and when a hard finger rod encounters obstacles such as stones, it will often cause broken teeth and damage due to rigid impact, affecting The picking operation is carried out normally; (3) The finger bar is straight, and when the slats are thin, the crops are easy to slip off the finger bar, resulting in a high rate of missed picking. And existing fruit-picking device is traditional tooth-type fruit-picking device, mainly adopts two kinds of fruit-picking modes of nail-tooth formula and comb formula. This eating type fruit-picking device picks peanuts by combing and hitting peanut plants through a toothed structure, which often easily leads to crushing of peanuts and crushing of peanut seedlings, resulting in difficulty in separating peanuts from peanut seedlings; When the peanuts are wet, this situation is more obvious, so the damage rate is higher, thereby affecting the development of the peanut industry.
