Problems solved by technology

It is well known that crop stalk cutting is an important process in the field operation of harvesters, and its cutting performance directly affects the harvesting efficiency of crops; field crop stalk cutting test parameters are important indicators to measure crop stalk cutting performance, but harvesting machinery is used to directly carry out When the field cutting test is used to obtain crop stalk cutting parameters, there are problems such as strong harvest seasonality, wildly different field planting conditions, poor test repeatability, high difficulty, and low accuracy of collected data.

Abstract

The invention relates to the technical field of cutter test bench equipment, and belongs to the field of agricultural mechanization. A cutter performance test bench mainly comprises dividers (1), reels (2), a speed reducer (8), a rack (9), an electric motor (11), a frequency converter (12), ground wheels (14), a slider crank mechanism (16), a cutter assembly (17) and the like. The machine is characterized by comprising a stage for the dividers (1), the speed reducer (8), the electric motor (11), the frequency converter (12) and the cutter assembly (17), wherein the stage is arranged on the rack (9), and mounting slots of the four ground wheels (14) are formed in the lower portion of the rack (9). According to the cutter test bench, various performance parameters of a cutter are measured through the frequency converter, and the frequency converter can regulate the speed of the cutter in the reciprocating moving process and can control the advancing speed of the whole machine. The test bench solves the problems that the cutter cuts different crops and the adaptability of the cutter mounted on various machines.

Description

technical field [0001] The patent of the present invention relates to the technical field of cutter performance test bench equipment, in particular to performance tests suitable for reciprocating cutters. Background technique [0002] The cutter performance test bench technology is specially used to test various performance indicators of the cutter. It is well known that crop stalk cutting is an important process in the field operation of harvesters, and its cutting performance directly affects the harvesting efficiency of crops; field crop stalk cutting test parameters are important indicators to measure crop stalk cutting performance, but harvesting machinery is used to directly carry out When the field cutting test is used to obtain crop stem cutting parameters, there are problems such as strong harvest seasonality, wildly different field planting conditions, poor test repeatability, high difficulty, and low accuracy of collected data.
