It should be noted that: in this embodiment, except for the design of the reverse driving mechanism 3, other structural components of the header system and the connection structure between the structures are basically the same as those of the existing header system (large), that is, the structures of the header system except for the reverse driving mechanism 3 belong to the prior art, and are not described herein, specifically, the transmission case 12, the snapping unit 13, the related components of the upper transmission shaft, the related components of the lower transmission shaft, the chain harrow 23, and the like all belong to the structural components of the existing header system.
In the operation process, the power of the engine is transmitted to the main belt pulley through the belt, then the power is transmitted to the auxiliary belt pulley through the belt at one end of the upper transmission shaft 22 at one side of the belt pulley component to drive the lower transmission shaft 21 to rotate, so that the chain harrow 23 is driven to rotate and convey, the transmission box 12, the conveying auger 11 and the ear picking unit 13 are driven to be linked through the universal shaft 211 (the operation of the lower transmission shaft 21 and other structures in the state is defined to be forward), and the other sides of the upper transmission shaft 22 and the lower transmission shaft 21 are linked through the chain and the driven chain wheel 221 and the driving chain wheel 212. When the cutting table body assembly 1 or the gap bridge 2 is blocked and clamped, the rotating speed of the lower transmission shaft 21 (or the upper transmission shaft 22) is reduced, when the rotating speed is reduced to about 10% (the set value can be flexibly set according to actual equipment), the power of the engine is controlled to be removed (namely, the power is not conveyed to the lower transmission shaft 21 any more), meanwhile, the reverse driving mechanism 3 is connected with the lower transmission shaft 21 and drives the lower transmission shaft 21 to reversely rotate, so that the chain harrow 23, the upper transmission shaft 22, the ear picking unit 13, the conveying auger 11, the transmission case 12 and the like which are linked with the lower transmission shaft are driven to reversely run in a normal state, namely, a reverse mode is started, the materials on the gap bridge 2 and the cutting table body assembly 1 are reversely conveyed and cleaned, and the clamped materials can be effectively cleaned. After the lower transmission shaft 21 or the upper transmission shaft 22 can be driven to rotate at a normal rotating speed (that is, after the rotating speed of the lower transmission shaft 21 or the upper transmission shaft 22 in a reverse rotating state is detected to be restored to the normal rotating speed in a forward rotating state, the material jamming of the whole system is finished), the reverse driving mechanism 3 is operated to be separated from the lower transmission shaft 21 to remove power (reverse power), then the lower transmission shaft 21 is connected with the power output of the engine again, the power of the engine continuously outputs to the lower transmission shaft 21, so that the gap bridge 2 and relevant units in the header body assembly 1 are driven to continuously operate in a forward direction again, in the whole design, the reverse driving mechanism 3 aims to reversely drive relevant operation components in the header body assembly 1 and the gap bridge 2 after the material jamming phenomenon occurs, and the gap bridge is cleaned.

In the above embodiment, the driven sprocket 221 is assembled at the shaft end of the upper transmission shaft 22 through the safety clutch 222, so that the upper transmission shaft 22 can be effectively protected when material jamming occurs (that is, when the upper transmission shaft 22 cannot rotate at normal speed due to material jamming, the safety clutch 222 is operated to separate the driven sprocket 221 from the upper transmission shaft 22, and forward power transmission is automatically removed), meanwhile, the safety clutch 222 can give a sound alarm to remind an operator when the forward power transmission to the upper transmission shaft 22 is removed, after the material jamming is cleared, and when the rotation speed of the upper transmission shaft 22 or the lower transmission shaft 21 can be recovered to be normal, the safety clutch 222 is operated to combine (drive-connect) the driven sprocket 221 and the upper transmission shaft 22, and the power of the engine is continuously transmitted to the lower transmission shaft 21 through the upper transmission shaft 22, so that forward power is accessed (operation of the safety clutch 222 belongs to a conventional technical means, and is not described herein).
The safety clutch 222 is a product in the prior art, and is often applied to agricultural machinery, and the connection relationship between the safety clutch and the shaft and the connection between the safety clutch and the driven sprocket 221 are all conventional mechanical structure connections, which are not described herein again.

In the above embodiment, after the material jamming phenomenon occurs, the rotation speed of the lower transmission shaft 21 is reduced, the forward power is removed to a certain extent, then the telescopic driving device 33 is extended to operate, so that the reverse pushing fixing frame 31 swings and approaches towards the side of the lower transmission shaft 21 until the driving gear 351 connected to the driving end of the rotary power driving device 35 is meshed with the driven gear 213, then the rotary power driving device 35 operates to drive the driving gear 351 to rotate, and at the same time the driven gear 213 is driven to rotate, that is, the lower transmission shaft 21 is driven to rotate (at this time, the rotation direction of the lower transmission shaft 21 is opposite to the rotation direction during forward operation), then the lower transmission shaft 21 can drive the chain harrow 23, the upper transmission shaft 22, the transmission box 12, the ear picking unit 13 and the conveying auger 11 to reversely operate, and reverse conveying and clearing blockage of the jammed materials on the header assembly 1 and the gap bridge 2.
What needs to be supplemented is: after the blockage is cleared, the rotating speeds of the lower transmission shaft 21 and the upper transmission shaft 22 are recovered, the telescopic driving device 33 retracts and drives the fixing frame 31 to swing until the driving gear 351 and the driven gear 213 are separated, then, the power of the engine is continuously transmitted to the lower transmission shaft 21, so that the header body assembly 1 and the gap bridge 2 continuously run in the forward direction, and in the process, the rebounding mechanism 34 provides the power for the fixing frame 31 to rotate, so that the fixing frame 31 can swing and return well.
In a preferred embodiment, the telescopic driving device 33 is a telescopic cylinder, the rotary power driving device 35 is a hydraulic motor, and the telescopic cylinder and the hydraulic motor are connected to a hydraulic system, which is connected to a controller.
In the above embodiment, after the rotation speed of the lower transmission shaft 21 or the upper transmission shaft 22 is reduced to the point that the power of the engine stops conveying the belt, the controller controls the hydraulic system to supply oil to the telescopic oil cylinder, the telescopic oil cylinder extends to drive the fixing frame 31 to swing, until the driving gear 351 and the driven gear 213 are meshed, the controller controls the hydraulic system to supply oil to the hydraulic motor to drive the hydraulic motor to operate, and drives the driving gear 351 and the driven gear 213 to rotate, so as to drive the lower transmission shaft 21 to rotate reversely, and start the reverse rotation blockage clearing mode.
In a preferred embodiment, a rotation speed sensor is provided on the upper transmission shaft 22 or the lower transmission shaft 21, and the rotation speed sensor is connected to the controller.
In the above embodiment, the rotating speed of the lower transmission shaft 21 or the upper transmission shaft 22 is monitored by the rotating speed sensor in real time and fed back to the controller, so that the controller can operate the forward or reverse operation of the whole machine in time according to the fed-back rotating speed condition.

In this embodiment, the elastic member 342 may be a conventional spring, and is sleeved outside the guiding rod 341, and the spring is gradually compressed when the fixing frame 31 swings toward the lower transmission shaft 21.
