Abstract

The utility model discloses a corn harvester header consisting of a harvester header bracket, as well as a power transmission device, a reeling device, a picking transmission device and a header travel guide guard shield positioned on the header bracket, wherein, a reeling chain and reeling teeth protrude out of the edges of the header travel guide guard shield. Since the reeling chain and the reeling teeth protrude out of the edges of the header travel guide guard shield, a significant increase in the contact between the reeling chain as well as the reeling teeth and corn stalks is caused, both corn stalks within reach of the utility model and partially lodged corn stalks can be harvested, thereby realizing corn harvesting without row alignment and improving work efficiency. The harvesting test gives evidence that the utility model greatly exceeds requirements for production and application of core harvesters concerning technical performance index, with net corn harvesting rate equalto or larger than 98 percent, fruit cluster loss rate smaller than 1.5 percent, grain damage rate smaller than 1 percent, and fruit cluster trash content smaller than 2.5 percent.

Description

The maize harvesting machine ceding of Taiwan

Technical field

The utility model relates to a kind of corn harvesting machine, relates in particular to a kind of maize harvesting machine ceding of Taiwan of using with tractor.

Background technology

Recent two decades comes, and China has introduced some external maize harvesting machine types in succession, and as the combined harvester of the U.S. Case company corn harvesting bench that changes the outfit, one-stop operation can be finished the operation of corn picker, threshing.Because northern China corn producing region is wheat, 1 year two batches of crop rotation growing area of corn especially, grain water content is up to more than 35% during harvest corn, adopt direct threshing mode to gather in the crops, the seed damage rate is very serious, according in September, 1980, ten thousand mu of square experiment stations measured in the Luancheng County, Hebei province, when 1440 type combined harvesters of U.S. Case company change the outfit behind the corn harvesting bench harvesting corn, seed damage rate average out to 14%, be up to 30%, total loss rate reaches 20%.And the harvesting approach of this direct threshing also is unfavorable for the corn after-ripening, and output is reduced.So harvest operation of this class facility incompatibility China two batches of crop rotation growing areas high-moisture percentage corn.Compare with developed country such as America and Europe, the corn planting of China has following characteristics: 1, the plantation plot is little, and 2, corn planting line-spacing disunity, 3, harvest corn phase grain water content is higher.At present, there is following defective mostly in the maize harvesting machine that China develops voluntarily: because row results are had relatively high expectations, and there is the skimble-scamble present situation of line-spacing in China's corn planting, thus can only single file or duplicate rows operation, inefficiency; Because it is ceding of Taiwan design is unreasonable, low for the corn net harvesting rate at half lodging and the edge of a field.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provides a kind of not to row results, high efficiency, the maize harvesting machine ceding of Taiwan that the corn net harvesting rate is high.

The technical solution of the utility model is: the maize harvesting machine ceding of Taiwan, by the harvester cutting bench support, be positioned at the power transmission on the ceding of Taiwan support, dial the standing grain device, plucking fringe conveying plant and ceding of Taiwan leading guard shield forms, described power transmission is: be positioned at the power input shaft on the ceding of Taiwan support, power input shaft is provided with power input wheel, left side driven pulley, right driven pulley, be positioned at the left gearbox under the power input shaft, right gearbox, a left side, right gearbox wheel for inputting import chain and left driven pulley into, right driven pulley is rotationally connected, a left side, right gearbox is provided with the gearbox output wheel, and power input wheel and tractor dynamic power output wheel are rotationally connected; Dialling the standing grain device is: be provided with two groups of open rice-pulling chain groups of symmetry at ceding of Taiwan support front end, described rice-pulling chain group is formed rice-pulling chain system by a plurality of platform rice-pulling tooths that are positioned at inboard platform driving wheel, slip thumb wheel, platform rice-pulling chain and firmly be connected on the rice-pulling chain, by two strands wheel, rice-pulling chain bar, slip thumb wheel outside being positioned at firmly be connected a plurality of rice-pulling tooths on the rice-pulling chain bar and form outer rice-pulling chain and be; Described double-stranded wheel is rotationally connected by output chain and gearbox output wheel; Also respectively be provided with on the left and right gearbox one group in relative rotation snapping bar form and to pluck the fringe conveying plant; On ceding of Taiwan support, be provided with and dial the standing grain device, pluck the ceding of Taiwan leading guard shield that fringe conveying plant profile adapts; It is characterized in that described rice-pulling chain bar and rice-pulling tooth protrude in outside the edge of ceding of Taiwan leading guard shield.

The beneficial effects of the utility model are: because rice-pulling chain bar and rice-pulling tooth protrude in outside the edge of ceding of Taiwan leading guard shield, strengthened contacting of rice-pulling chain bar and rice-pulling tooth and corn stalk greatly, the corn stalk that can will touch corn stalk and half lodging is completely included the results scope in.Historical facts or anecdotes showed to corn to row results, improved operating efficiency.Through gathering in the crops evidence: the utility model corn net harvesting rate 〉=98%, fruit ear percent of loss＜1.5%, seed damage rate＜1%, fruit ear percentage of impurity＜2.5%.Be much higher than the technical performance index requirement that the maize harvesting machine production application need reach.
