Abstract
The utility model provides a seedling-pulling chain-driving mechanism of an ear-picking platform of a corn harvester and belongs to the agricultural machinery. An ear-picking platform frame is provided with a worm and worm gear transmission box body; the worm and worm gear transmission box body accommodates the front side of an ear-picking roller; a worm is arranged on the front side of the ear-picking roller and in the worm and worm gear transmission box body; a power output shaft is arranged on the worm and worm gear transmission box body; a worm gear and a chain wheel are fixedly arranged on the lower side and the upper side of the power output shaft respectively, and the worm gear is positioned in the worm and worm gear transmission box body and meshed with the worm; and the chain wheel is positioned on the outer part of the upper side of the worm and worm gear transmission box body and is sleeved and matched with the seedling-pulling chain. The mechanism is novel in design, has a simple and reasonable structure and a good operating effect, is low in manufacturing cost, low in failure rate, low in operating noise, low in operating vibration and light in structural weight, and operates reliably.
Description
Technical field
The invention belongs to agricultural machinery, relates generally to and drives the mechanism that the ear harvesting bench rice-pulling chain drives on a kind of harvest corn facility.
Background technology
On used all kinds of model maize harvesting machine tools, snapping bar on its ear harvesting bench and the motion of rice-pulling chain are finished by independently of one another power drive system driving, be that snapping bar has a cover power-driven system, rice-pulling chain must arrange again the power-driven system that a cover is made of parts such as speed-changing gear boxs, just must be equipped with the quadruplet system and drive respectively four rice-pulling chains and finish revolution group standing grain and move on the harvest corn facility of two row.Obviously, drive mechanism is complicated, manufacturing cost is high, mostly the operation fault is to solve the ground technical problem, simultaneously, because this structure has increased the corn picking platform overall weight, property easy to adjust and harvest operation effect when having affected the ear harvesting bench harvest operation.
Summary of the invention
The purpose of the invention is exactly the problem that exists for above-mentioned prior art, design provides a kind of ear picking bench of corn harvester rice-pulling chain driving mechanism of new construction, reaches the purpose of simplified structure, reduction manufacturing cost, minimizing operation fault, the ear harvesting bench overall weight that alleviates, assurance operation quality.
The Basic Design of the invention is, a kind of ear picking bench of corn harvester rice-pulling chain driving mechanism comprises the harvesting stand and is fitted in snapping bar on the harvesting stand, rice-pulling chain is led device with holding up, at the harvesting stand Worm Wheel System casing is installed, described Worm Wheel System casing contains the front side portion of snapping bar, on the snapping bar front side portion, be positioned at the Worm Wheel System box house and be fixedly mounted with worm screw, power take-off is installed on the Worm Wheel System casing, worm gear and sprocket wheel are packed in respectively on the downside position and upside position of power take-off, and described worm gear is positioned at the Worm Wheel System box house, intermeshing with worm screw, it is outside that described sprocket wheel is positioned at Worm Wheel System case upside, and cooperate with the rice-pulling chain socket.Hold up lead on the device, be positioned at the Worm Wheel System casing above the equipped Lubricating oil barrel in position, lubricating oil return pipe and lube oil outlet pipe are communicated with Lubricating oil barrel respectively with the Worm Wheel System casing, the formation circulating oil path.
The rice-pulling chain drive system of standing separately setting on existing each model maize harvesting machine has been cancelled in the invention, employing directly drives the structure that rice-pulling chain is done gyration by the snapping bar rotary power through the worm and gear gearbox, realize the rice-pulling chain power drive, have modern design, rational in infrastructure simple, cheap for manufacturing cost, operation is reliable, fault is few, the operation noise is little, operation vibration and lightweight construction, characteristics that operation effectiveness is good.
