specific Embodiment approach example 1

[0008] Specific implementation example 1: in conjunction with attached picture The present invention is further outlined, and several conical drums are arranged side by side at the front end of the harvester to see, picture . Outside the drum is a 6-shaped valley baffle see picture . When the cone separates the rice stalks to the part with batting teeth, the threshing wheel pushes the ears of rice into the drum for threshing. picture . The rear part of the drum does not have batting teeth, but only a scraper to send the grain out of the drum, see picture . The mowing shears below the drum simultaneously cut the straw, see picture .

specific Embodiment approach example 2

[0009] Specific embodiment example 2: this example harvests early rice, after the mowing shears cut off the straw under the drum, the grass feeding chain will reversely rotate, and the straw will be cut into pieces, and all the other are the same as example 1.

specific Embodiment approach example 3

[0010] Specific implementation example 3: In this example, single-crop rice is harvested. After the mowing shears under the drum cut the straw, the grass-feeding chain and the grass-feeding wheel rotate in the same direction, and the straw can be sent out from two directions on one side so that the straw can be recycled. Same example 1.

Abstract

The invention discloses a conical multi-roller direct-harvest harvester, which is a harvester having a simple structure. The principle is that: rice is directly threshed on conical rollers by utilizing tension of soil on a root system of the rice; when straws are separated by cones, a rice ear pressing wheel rotates to introduce rice ears into rollers on the inner side of a 6-shaped rice blocking plate so as to thresh the rice; meanwhile, spiral rice scraping plates are arranged on the threshing rollers so as to convey the rice out of the rollers, and after the rice is threshed, the rice ears are withdrawn from a grain striking roller. At the moment, a lower mowing shear shears the straws, and a straw feeding wheel feeds the straws into a conveying chain. In the process of harvesting early season rice in a double crop rice region, a knife chain is arranged on the conveying chain to cut up the straws.

Description

Technical field: [0001] The invention is a new type of harvester, which specifically uses the pulling force of the soil on the rice root system to thresh. Background technique: [0002] Various traditional harvesters adopt the original artificial principle of cutting first and then threshing, with high power, complex structure and heavy overall weight. Invention content: [0003] The invention utilizes the pulling force of the soil on the root system of the crops to directly thresh on the conical drum, saves the work process, overcomes the shortcomings of the background technology, and provides a harvester with simple structure, light weight, convenient use and easy maintenance. [0004] The invention utilizes the pulling force of the soil on the crops to directly thresh on the drum, thereby greatly reducing the working process, reducing the weight and simplifying the mechanical structure. [0005] The specific technical scheme of the conical multi-drum direct-harvesting ...
