Peanut harvester

Abstract

The invention relates to the technical field of agricultural machinery accessory devices, in particular to a peanut harvester. Harvested peanut seedlings can be laid together, subsequent bundling of the peanut seedlings is facilitated, and the use reliability is improved; the soil removing effect of the peanut seedlings is improved, and the practicability is improved. The peanut harvester comprises a rack, and a traction frame, a deep and shallow roller, a scraper knife, a front conveying device, a rear conveying device and a driving device for driving the front conveying device and the rear conveying device are arranged on the rack. The peanut harvester also comprises an oil pump, a hydraulic oil pipe, a mounting rod, a hydraulic oil cylinder, a left seedling blocking plate, a right seedling blocking plate and a connecting rod; the front conveying device comprises two rotating shafts and three conveying chains, the two ends and the middles of the two rotating shafts are each providedwith a conveying chain wheel, a plurality of groups of reinforcing bars are arranged between the three conveying chains, and the reinforcing bars are parallel in pairs; scraping plates are arranged onthe inner sides of the reinforcing bars; the scraping plates are fixedly connected with the reinforcing bars through bolts.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery attachments, in particular to a peanut harvester. Background technique [0002] As we all know, the peanut harvester is a kind of agricultural machinery used in the peanut harvesting process to excavate and remove the soil through mechanization, which greatly reduces labor costs, and has been widely used in the field of agricultural production; the existing The peanut harvester includes a frame on which a traction frame, deep and shallow rollers, a blade, a front conveying device, a rear conveying device and a driving device for driving the front conveying device and the rear conveying device are arranged.

[0002] As we all know, the peanut harvester is a kind of agricultural machinery used in the peanut harvesting process to excavate and remove the soil through mechanization, which greatly reduces labor costs, and has been widely used in the field of agricultural production; the existing The peanut harvester includes a frame on which a traction frame, deep and shallow rollers, a blade, a front conveying device, a rear conveying device and a driving device for driving the front conveying device and the rear conveying device are arranged. The input end of the front conveying device is located at the blade The output end of the rear conveying device is located directly below the output end of the front conveying device; when the existing peanut harvester is used, the traction frame is connected with the agricultural machine, and the agricultural machine drives it to move, and the peanut seedling is scooped up by the spatula. The shoveled peanut seedlings are conveyed backward through the front conveying device. During the conveying process, the peanut seedlings are removed from the soil. The peanut seedlings are conveyed from the front conveying device to the rear conveying device, and then output from the output end of the rear conveying device to complete the peanut seedlings. laying of seedlings; in the use of the existing peanut harvester, it is found that the peanut seedlings laid by it are relatively disorderly, which is inconvenient for subsequent bundling of peanut seedlings, resulting in low reliability in use; and its removal of soil from peanut seedlings Less effective, resulting in less useful
