Forced blockage-removing mechanism suitable for furrow opener of rice stubble field

Abstract

The invention relates to a forced blockage-removing mechanism suitable for a furrow opener of a rice stubble field, which is characterized in that a rotary cultivator is arranged at a position close to the furrow opener, so that an end part of a rotary tillage bending knife of the rotary cultivator is close to the front of a lower part of the furrow opener but is not in contact with the rotary cultivator; a rotating shaft of the rotary cultivator is additionally provided with a plurality of side blockage-removing straight knives, a rotating radius of an outermost end of the straight knives islarger than the rotating radius of the outermost end of the rotary tillage bending knife, and the side blockage-removing straight knives are close to one side of the furrow opener but is not in contact with the furrow opener. By the adoption of the forced blockage-removing mechanism suitable for the furrow opener of the rice stubble field, sundries and clay are not easy to accumulate in the frontof the furrow opener; the front part and a single side of the furrow opener are respectively subjected to forced blockage-removing by the rotary tillage bending knife and the side blockage removal straight knives so as to ensure that no accumulation exists in the front of the furrow opener; compared with a drum-type mechanism or other passive anti-blocking devices, the blockage-removing mechanismhas the advantages of being better in anti-blocking effect under a condition of sticky soil in the rice stubble field, compact in structure, composite in functions, cost-saving and more effective.

Description

technical field [0001] The invention relates to an agricultural mechanical device, in particular to a forced plugging mechanism suitable for ditch openers in rice stubble fields. Background technique [0002] The opener is an important part of the seeder. Fertilization in the right position requires the opener to open a deep ditch to apply the fertilizer to a fixed position. In the case of heavy clay soil or a lot of straw and weeds, clay or sundries are easy to block In front of the openers, resulting in poor or inoperable implement performance. In response to this problem, some existing seeders have designed a freely rotatable drum mechanism or other passive anti-blocking devices in front of the openers, which can prevent straw entanglement and blockage to a certain extent. However, this passive anti-blocking mechanism cannot ensure no clogging when working in sticky and heavy soil, because the clay will stick to the surface of the anti-blocking mechanism, accumulate more...
