Self-walking wheat and rice cutting, sunning and laying machine

Abstract

The invention relates to a self-walking wheat and rice cutting, sunning and laying machine, which comprises a rack. A cutting mechanism is arranged at the front part of the rack. A stalk divider and a stalk lifter are respectively arranged on the two sides of the front part of the rack. A conveying and laying mechanism and a transmission mechanism are arranged at the middle part of the rack. A walking mechanism is arranged at the rear part of the rack. The machine additionally comprises a crank sliding block mechanism arranged on one side of the middle part of the rack. The crank sliding block mechanism is provided with a crankshaft. A horizontal input belt wheel is arranged at the upper end of the crankshaft. A supporting and connecting bearing seat is arranged at the lower end of the horizontal input belt wheel. A conveying belt wheel I is arranged at the middle part of the crankshaft. A reel I is sheathed on the conveying belt wheel I. An eccentric crank is arranged at the lower end of the crankshaft. A roller is arranged on the lower side of the eccentric crank. A sliding block is arranged at the lower end of the eccentric crank. The roller is installed in the sliding groove of the sliding block. The self-walking wheat and rice cutting, sunning and laying machine has the advantages that the overall structure is novel, the size is small, the weight is light, the machine is mobile and flexible, the machine is convenient to operate, the adaptability is strong, the turning radius is small, wheat and rice can be laid tidily and the machine is particularly suitable for harvesting film-mulched wheat which is fully covered by films and is planted in a soil moisture conserving way in current dry farming.

Description

technical field [0001] The invention relates to the field of wheat and rice harvesting machinery, in particular to a self-propelled wheat and rice harvesting and laying machine. Background technique [0002] At present, there are many kinds of wheat and rice harvesting and laying machines in China, which are used in conjunction with four-wheel tractors. linkage mechanism etc. The reciprocating motion of the movable knife rod of the cutter pushes and pulls the knife rod by the deformation of the spring flat steel riveted on the movable knife rod, and the spring flat steel is driven by the swing arm of the swing ring mechanism. In order to keep the gap between the fixed knife and the moving knife unchanged, the longer the spring flat steel is, the smaller the deformation will be, and the angle between the moving knife rod and the swing arm will be smaller, and the spring flat steel will not be broken due to fatigue. , but to ensure that the gap between the moving knife and ...
