Furthermore, the small chain wheel shaft is arranged at the lower part of the front end of the fixed frame and mainly used for supporting the small chain wheel and rotating together with the small chain wheel to transmit power.

Furthermore, the small chain wheels are arranged at two ends of the small chain wheel shaft and are positioned in the fixing frame, and the small chain wheels are mainly used for completing transmission of the transmission chain and preventing the transmission chain from deviating.

Furthermore, the lifting chain wheel shaft is arranged at the upper part of the middle of the fixing frame and mainly used for supporting the lifting chain wheel and rotating together with the lifting chain wheel.

Furthermore, the lifting chain wheel is installed at the two ends of the lifting chain wheel shaft and located in the fixing frame, and the main function is to lift the transmission chain.

Furthermore, the large chain wheel shaft is arranged on the upper part of the rear end of the fixed frame and mainly used for transmitting power and providing power for the lifting chain.

Furthermore, the big chain wheel is arranged at two ends of the big chain wheel shaft and is positioned in the fixing frame, and the main function is to transmit the power of the big chain wheel shaft to the transmission chain so as to enable the transmission chain to rotate.

Furthermore, the transmission chain is arranged on the small chain wheel, the lifting chain wheel and the large chain wheel, and forms an elevating chain together with the connecting rod group, and the transmission chain is mainly used for conveying potatoes to move backwards and has the potato-soil separation effect in the conveying process.

Furthermore, the connecting rod group consists of a connecting rod and a movable rod sleeve, and the connecting rod is arranged on the transmission chain and mainly used for supporting the movable rod sleeve; the movable rod sleeve is arranged on the connecting rod, when the connecting rod group is arranged at the front end of the transmission chain, the movable rod sleeve is supported by the guide plate below, the distance between the connecting rods becomes small, when the connecting rod group is arranged at the rear end of the transmission chain, the guide plate is not supported below the movable high sleeve, under the action of gravity, the movable rod sleeve rotates, and the distance between the connecting rods becomes large.

Furthermore, the guide plates are arranged on two sides in the fixed frame and positioned below the front end of the transmission chain, and are mainly used for limiting the state of the movable rod sleeved at the front end of the transmission chain so as to realize the front-back change of the rod distance.

The during operation, with power transmission to big sprocket shaft, realize the rotation of driving chain to drive connecting rod group and move along with the driving chain, owing to there is the existence of baffle at the driving chain front end, the movable rod cover in the connecting rod group is supported by the baffle, makes the interval of connecting rod diminish, and at the rear end of driving chain, does not have the existence of baffle, and the movable rod cover in the connecting rod group takes place to rotate under the action of gravity, and at this moment, the interval grow of connecting rod.

According to the technical scheme, compared with the prior art, the potato lifting chain with the variable spacing is simple in structure, the pitch of the rods can be changed in the conveying process of potatoes, so that the grading of the potatoes is realized, the problem of grading after the potatoes are harvested is solved well, the damage to the potatoes in the conveying process is greatly reduced, the labor intensity is greatly reduced, and the production efficiency is improved.
