Grain scrabbling device for grain collecting vehicle and method for operating grain scrabbling device

Abstract

The invention relates to a grain scrabbling device for a grain collecting vehicle and a method for operating the grain scrabbling device, and belongs to the technical field of agricultural machinery and equipment. The grain scrabbling device comprises a platform. The platform is provided with a drawing shell via a parallel four-bar linkage mechanism, a third motor is hinged onto the platform, a threaded sleeve is hinged to the rear end of the drawing shell and is connected with a rotary shaft of the third motor in a threaded manner, grain scrabbling augers and a prismatic separation frame aremounted in the drawing shell, shells of the grain scrabbling augers are jointly formed by the drawing shell and the prismatic separation frame, and a grain suction pipe for sucking grain by the aid ofnegative pressures is arranged on the rear end surface of the drawing shell in a communicated manner. The grain scrabbling device has the advantages that the mode for sucking the grain by the aid ofthe grain scrabbling augers assisted by the grain suction pipe is adopted, and accordingly the efficiency can be improved when the grain is gathered at grain suction openings of the grain suction pipe; common grain scrabbling equipment in the prior art is structurally optimized, the volume of the common grain scrabbling equipment is compressed, the common grain scrabbling equipment is concentratedat the grain suction pipe and is used as auxiliary means for improving the grain suction efficiency of the grain suction pipe, accordingly, power distribution key points of transmission systems can be highlighted, the volume of equipment can be reduced, and load on engines can be relieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery equipment, in particular to a grain picking device for a grain collection vehicle and an operating method thereof. Background technique [0002] In 2015, the sown area of ​​grain crops nationwide was about 113.34 million hectares, and the total output value of grain planting was about 1,886.4 billion yuan, a decrease of about 6.51% from the previous year. The total profit was about 33.2 billion yuan, down 84.25% from the previous year. [0003] The decline of the grain industry in 2016 further deepened the impact on the macro economy. In 2016, the net profit of grain production declined, and the total profit of farmers growing grain was -136 billion yuan, a decrease of 169.2 billion yuan from the previous year. Considering that the marginal propensity to consume in rural areas increased to 0.82 in 2016, the decline in net profit of residents resulted in a GDP decline of 935.9 bill...

Problems solved by technology

[0013] Aiming at the problem that the structure of the grain collecting parts of the existing grain harvesting machine is huge, but the grain harvesting efficiency cannot be effectively improved, the present invention provides a grain picking device for a grain collecting vehicle and its operation method. The functional system is assembled and used in series, forming a grain collection mode that mainly absorbs grain and supplemented by picking up grain, improves the use efficiency of the grain absorption system, and saves the grain transmission parts of the grain picking system in the prior art , compressing the volume of the grain harvester
