Two-wheel single-joint profiling ground wheel assembly

Abstract

The invention relates to a double-wheel single-hinging profiling ground wheel assembly and belongs to agricultural machinery. A connecting plat is hinged on a beam frame, a power output shaft is fixedly arranged on a driven chain wheel and is inserted in the connecting plate in a matching manner, two ends of a bidirectional hydraulic oil cylinder are respectively hinged on the beam frame and the connecting plate, a ground wheel bracket is hinged on the lower side part of the connecting plate, central shafts are fixedly arranged on a driving chain wheel and an overrunning clutch and are inserted into the connecting plate and the ground wheel bracket in a matching manner, a first driven chain wheel and a second driven chain wheel are fixedly arranged on the exterior of the overrunning clutch, a first driving ground wheel and a second driving ground wheel are arranged on two side parts of the ground wheel bracket, a first driving tower chain wheel and a second driving tower chain wheel are respectively fixedly arranged on a first driving ground assembly and a second driving ground assembly, a main driving chain is sleeved on the driven chain wheel and a driving chain, a first drivingchain and a second driving chain are respectively sleeved on the first driving tower chain wheel and the first driven chain wheel, and a second driving tower chain wheel and the second driven chain wheel. The double-wheel single-hinging profiling ground wheel assembly disclosed by the invention has the advantages of simple, novel and reasonable structure, enough driving power for operation, good profiling performance and reliability for using.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operation assembly on a large-scale mechanical sowing and fertilizing machine tool. Background technique [0002] At present, on the sowing and fertilizing equipment equipped with various mechanical seed meters and fertilizer applicators, the rotational power generated by the contact between a single ground wheel and the ground is used as a mechanical seed meter and fertilizer applicator to complete the sowing and fertilization operations. power source. In actual operation, due to differences in natural conditions, including differences in field levelness, soil moisture content, soil specific resistance, etc., sometimes a single wheel is out of contact with the ground surface, causing the ground wheel to stop rotating, resulting in seed metering and The failure of the fertilizer applicator to work is also due to insufficient driving power of a single ground wheel, resulting in t...

Problems solved by technology

In actual operation, due to differences in natural conditions, including differences in field levelness, soil moisture content, soil specific resistance, etc., sometimes a single wheel is out of contact with the ground surface, causing the ground wheel to stop rotating, resulting in seed metering and The failure of the fertilizer applicator to work is also due to insufficient driving power of a single ground wheel, resulting in the ground wheel stalling and unable to perform operations. This not only reduces the operating efficiency, but also seriously affects the quality of sowing and fertilization operations, and the rate of missed sowing and missed application increases.
