Description

Pickup device of peanut harvester

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to a picking device of a peanut harvester.

Background

Peanuts are important economic crops in China, and the planting area of the peanuts in China is very wide, so that the peanut harvesting mechanized operation has great economic benefit. The peanut combine harvester with the pickup is an important machine type in the two-section peanut harvesting link in China at present due to the advantages of large feeding amount, high harvesting efficiency and the like. The two-stage peanut harvesting mainly comprises the following steps: after the peanuts are ripe, firstly digging the peanuts by using a peanut digging machine, removing soil, drawing and paving the peanuts in a field, and picking up and picking the peanuts by using a peanut combine harvester with a pickup after the peanuts are dried.

The pickup device is one of the key components of the peanut pickup harvester, the performance and the working quality of the pickup device not only directly influence the ground pickup rate of peanut plants and the peanut pod dropping loss rate, but also influence the peanut pickup speed and further influence the whole machine harvesting efficiency of the harvester. The peanut picking device has a plurality of influencing factors, wherein the peanut picking device mainly comprises the types of peanut plants, laying and airing conditions after picking and collecting. The types of peanut pickup devices applied in China are divided into toothed belt type, elastic toothed drum type and tooth raking combined type, wherein the elastic toothed drum type is divided into a slide type pickup device and a non-slide type pickup device. The toothed belt type pickup device is only applied to small peanut pickup harvesters with small breadth of harvesting operation and low advancing speed of a unit due to the limitation of the pickup breadth and the rotating speed. At present, the medium-sized peanut picking harvester still mostly adopts an elastic tooth drum type and tooth raking combined type picking device. For the slideway type elastic tooth roller picking device, the roller repeatedly impacts the cam disc in the cam slideway to cause fatigue damage of the cam disc, and the picking device periodically vibrates to reduce the applicability and stability of the picking device. And no slide formula bullet tooth cylinder pickup attachment, bullet tooth and cylinder do not have relative swing, rely on the camber change of upper guard plate radian to solve the bullet tooth and to peanut plant the control effect, but increased the pick-up height, make the peanut plant form "hillock". Hug tooth combination formula pickup attachment, adopt to hug the fluted roller and play tooth cylinder pickup attachment cooperation and use, can prevent effectively that the peanut plant "from blockking up and piling", nevertheless formed the secondary to the peanut plant and hit and beat, increase the peanut and fall fruit rate and loss rate.

Chinese patent publication No. CN112400478A discloses a shovel tooth-spring tooth roller combined peanut pickup device, belonging to the technical field of agricultural machinery. The picking device comprises picking shovel teeth, roller protection plates, picking rollers, roller slide ways and side plates, wherein a central shaft of each picking roller penetrates through the side plates on two sides and is respectively installed on a bearing seat, the picking elastic teeth are uniformly arranged on elastic tooth shafts of the picking rollers at intervals, the roller protection plates are arranged between adjacent picking elastic teeth, and arc-shaped picking shovel teeth with the same structure are installed at the same position on each roller protection plate at the advancing front end of the picking device to form a row of shovel teeth; the roller slideway is fixedly arranged in one side plate and is in sliding connection with the elastic tooth shaft on the picking roller, and peanut plants are shoveled by the shoveling teeth; through picking up the cylinder and rotating along the cylinder slide, because the restriction of cylinder slide, the bullet tooth rotates and the periodic repeated swing around the center pin along with the cylinder, realizes the action that the bullet tooth lifted, propelling movement and sky returned the station. And the impact of the roller on the cam slideway can be effectively reduced, the greater stress concentration is avoided, and the service life of the cam slideway is prolonged.

However, when the pick-up device works, the tooth tips of the elastic teeth lack buffering before entering the soil, and the elastic teeth are impacted greatly, which is not beneficial to prolonging the service life of the elastic teeth.
