Abstract
The present invention discloses a cutting platform transmission device of a half-feeding harvester for rice and wheat, which comprises two stages of speed reducing transmission, wherein the first stage is chain transmission, transmission is carried out by an intermediate transmission box (1) and a transitional transmission shaft (8) which are arranged on a combine body through a chain (7); the second stage is belt transmission, transmission is carried out by the transitional transmission shaft (8) and a dynamic force input wheel of a cutting platform through a belt (10), and one side of the belt (10) is provided with an automatically tensioning and separating mechanism of a belt. The tensioning and separating mechanism is linked by utilizing the control of lifting characteristics in the harvesting operation of a harvester through the automatically tensioning and separating mechanism, so that the transmission belt (10) of a cutting platform automatically tensions or separate, and the cutting platform can automatically bind or cut off dynamic force. The present invention guarantees that harvesters can always keep stable cutting and conveying speed, so the harvesting performance of harvesters is largely enhanced. The present invention replaces the one-way clutch transmission structure with low reliability and high price, so the loads of speed variators and traveling gear boxes are largely reduced, the service lives of harvesters are prolonged, and the manufacture cost and the use cost of harvesters are lowered.
Description
Technical field
The present invention relates to a kind of transmission device of the semi-feeding combine harvester ceding of Taiwan.
Background technology
At present, the transmission device of the semi-feeding combine harvester ceding of Taiwan is an outrigger shaft by the walking gearbox that driven by hydraulic continuously variable transmission, and the one-way clutch that is loaded on the outrigger shaft is formed.When machine is in the harvesting state, when advancing, power through hydraulic continuously variable transmission, walking gearbox and one-way clutch, is passed to the ceding of Taiwan from engine, makes ceding of Taiwan running; When machine retreats, the not transferring power because one-way clutch reverses, the ceding of Taiwan is not turned round, to satisfy the harvesting performance requirement of semi-feeding combine harvester.But, there is following defective in this one-way clutch drive mechanism: (1) is when crops such as harvesting lodging or humidity, the machine speed of travel is slower, the transmission speed of one-way clutch is also slower, ceding of Taiwan cutting and transporting velocity are low excessively, cause cutting not smooth easily, poor stability, problem such as field loss is big; (2) the one-way clutch service condition is abominable, and the life-span is short, the cost height; (3) because the power of the ceding of Taiwan transmits through buncher and walking gearbox, increase the load of the two, reduced the service life of buncher and walking gearbox.
Summary of the invention
Limited by the speed of travel in order to overcome existing one-way clutch transmission speed, service life is short, the cost height, increase the defectives such as load of buncher and walking gearbox, the invention provides a kind of easy, practical transmission device, this device can not only realize having identical transmission and operating function with existing one-way clutch transmission device, and can improve the harvesting stability of machine greatly, improve the service life of transmission device, reduce use cost.
The technical solution adopted for the present invention to solve the technical problems is: it comprises the double reduction transmission, the first order is chain drive, middle driving box that is provided with by body and transition power transmission shaft are by chain drive, the second level is belt transmission, pass through belt transmission by transition power transmission shaft and ceding of Taiwan power input wheel, belt one side is provided with belt auto-tensioning separating mechanism.
Belt auto-tensioning separating mechanism comprises regulating wheel, tensioning support, tensioning spring and separates flexible axle in the present invention; Separating flexible axle one end is connected with the ceding of Taiwan transmission case of grain header, the other end is connected with the rear end of tensioning support, tensioning spring one end is connected with body, the other end is connected with the postmedian of tensioning support, the middle front part of tensioning support is equipped with regulating wheel, front end then is articulated on the body, and regulating wheel is positioned at belt one side; Described separation flexible axle is a Bowden cable.
After adopting as above technical scheme, when the ceding of Taiwan is in harvesting state (ceding of Taiwan is overhead nearest), the one separation flexible axle that is terminated on the ceding of Taiwan transmission case body is in relaxed state, regulating wheel is tensioning ceding of Taiwan driving belt under the tension of tensioning spring, power from engine, through middle driving box, transition power transmission shaft, import ceding of Taiwan power input wheel into, drive ceding of Taiwan running; By handling the taiwan cut off and landing oil cylinder, make the ceding of Taiwan rise to certain altitude, interlock separates flexible axle, upwards spurs the tensioning support, overcomes the pulling force of spring, and ceding of Taiwan belt is separated, and the ceding of Taiwan shuts down.The present invention guarantees that semi-feeding combine harvester remains stable cutting and transporting velocity, overcome existing one-way clutch drive mechanism when harvesting lodging or moist crop, slowly the ceding of Taiwan input speed that causes because of the speed of travel is low excessively, thereby cause gathering in poor stability, the deficiency that field loss is big; Alleviate the load of buncher and walking gearbox, improve service life; Reduce manufacturing cost and use cost, improve the reliability of ceding of Taiwan transmission.
