Cutting table of high-stalk crop harvesting machine

Abstract

The invention discloses a cutting table of a high-stalk crop harvesting machine. The technical scheme includes that the cutting table comprises a mounting plate, a cutting knife, standing grain pulling devices and conveying devices; the standing grain pulling devices comprise bases, standing grain pulling rods and driven chain wheels, first rotary shafts and second rotary shafts are hinged onto the bases, cranks and rockers are arranged between the standing grain pulling rods and the bases, one end of each crank is hinged to the middle of the corresponding standing grain pulling rod, the otherend of each crank is fixedly connected with the corresponding first rotary shaft, two ends of each rocker are hinged to the rear end of the corresponding standing grain pulling rod and the corresponding second rotary shaft, the driven chain wheels are arranged on the first rotary shafts, the conveying devices comprise mounting columns, conveying wheels and conveying belts, the conveying wheels are arranged on the mounting columns, the conveying belts are arranged between the conveying wheels, and standing grain pulling fingers are arranged on the conveying belts. The cutting table has the advantages that stalk gathering actions during manual harvesting can be simulated by the standing grain pulling devices, stalks on two sides of the cutting table can be gathered and pulled towards the middle of the cutting table, and accordingly crops can be pulled, cut and conveyed by the cutting table; only the front ends of the standing grain pulling rods can extend out of the front of the cuttingtable, and accordingly the integral cutting table is small in occupied space.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a high-stalk crop harvester header. Background technique [0002] Harvesting is a key link in the production process of high-stalk crops (such as hemp, reed, and corn, etc.). Due to the high stalks of high-stalk crops, the labor intensity and low efficiency of manual harvesting are difficult to meet the development requirements of modern agriculture. Therefore, the development of high-stalk crop harvesting machinery with simple structure, high reliability and good operation quality has become an urgent demand for industrial development. The header is an important part of the high-stem crop harvester, and its working quality directly affects the working performance of the whole machine. The existing high-stalk crop harvester headers usually use several wheeled reeders arranged side by side to move the crops to the header, and the stalks are cut off by the cutte...

Problems solved by technology

However, due to the taller plants of tall crops, a slight inclination of the stalks will block the cutting table, resulting in the inability to convey the subsequent stalks. At the same time, the side-by-side repellers are also easy to push the stalks down, resulting in an increase in the failure rate of machine harvesting. Seriously affect the quality of mechanical work, which is not conducive to the realization of mechanization in the harvesting of high-stalk crops
