Self-propelled peanut picking-up and fruit picking combine harvester

Abstract

The invention relates to a peanut combine harvester, in particular to a self-propelled peanut picking-up and fruit picking combine harvester. The self-propelled peanut picking-up and fruit picking combine harvester comprises a picking-up device, a middle conveying device, a fruit picking device, a multi-level cleaning device, a hoisting conveying device and a fruit collecting device which are sequentially connected, and a power device is connected with all the devices respectively. The self-propelled peanut picking-up and fruit picking combine harvester realizes the combined operation integrating picking-up, conveying, fruit picking, cleaning, hoisting and fruit collecting of laid peanuts, is high in picking-up efficiency and picking rate, improves the integrity of the peanuts to the maximum degree, and effectively solves the problem that fruit and seedlings cannot be separated thoroughly or cleaned cleanly.

Description

technical field [0001] The invention relates to a peanut combined harvester, in particular to a self-propelled peanut picking and fruit picking combined harvesting machine, which is suitable for combined picking and fruit picking of multiple rows of 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 used for food, peanuts are also used in printing and dyeing and paper making industries. Peanut is also a traditional Chinese medicine, which is suitable for symptoms such as malnutrition, spleen and stomach disorders, cough, phlegm and asthma, and lack of milk. Peanuts are rich in fat and protein, which is not only the main source of edible vegetable oil, but also rich in vegetable protein. The protein powder using peanuts or defatted peanut cakes can be directly used for baking, an...

Problems solved by technology

Among them, the pick-up device has the following problems: (1) the pick-up width is 1-2 lines, and the operation efficiency is low; (2) the pick-up device uses an elevator-type pick-up device for picking up, which takes up a lot of space, uses a lot of materials, and costs high , the drop rate is relatively large; (3) The pick-up finger is rigid linear, with high strength, and has a large impact on the material when picking up. ) Picked up peanut seedlings are easily entangled on the pick-up finger, affecting the next operation

This device has the following problems: (1) if the wind blown by the fan is too large in this form, the peanuts are easily blown out of the machine, causing the loss rate of peanuts to be too high; It is not easy to blow the impurities out of the machine, resulting in high impurity content of the harvest; (2) Since the air outlet of the fan is facing the gap of the vibrating screen, some large stones and soil blocks are easy to fall into the fan, causing Blockage and damage of the fan; (3) If the feeding amount of peanuts is too large, the peanuts will be stacked on the vibrating screen, so that the impurities caught in the middle are not easy to be blown out of the machine

This device has the following problems: (1) Since the fan is installed above the vibrating screen, the air duct blows along the direction perpendicular to the vibrating screen, and the impurities with large volume are not easy to be blown out of the machine; (2) if the peanuts are fed If the input is too large, the peanuts will be stacked on the vibrating screen, so that the impurities caught in the middle are not easy to be blown out of the machine

These lifting devices have the following problems: (1) The spiral conveying type lifting device lifts the peanuts due to the rotating motion of the helical surface, so when there are many peanuts, it is easy to slide; (2) the scraper conveying type lifts The transportation device is divided into an upper scraping lifting device and a lower scraping lifting device

The upward scraping conveying and lifting device is easy to crush the peanuts at the chain and sprocket; (3) the downward scraping conveying and lifting device is not clean for unloading the fruit, and the fruit is easily pinched between the scraper and the shell; (4) ) Since the scraper is made of metal material, it is easy to cause a large impact on the peanut seedlings when it contacts the peanut seedlings, increasing the breakage rate; because the scraper adopts a right-angled structure, it is greatly affected by vibration during movement, which is easy to cause fruit drop
