The minimum gap between the tail end of the disturbance roller tooth on each disturbance roller and the conveying surface of the conveying screen assembly is gradually changed, and the minimum gap can be realized by replacing the support beam group of the soil removal assembly into a telescopic support rod, and the telescopic support rod can be an electric push rod or an air cylinder or a hydraulic cylinder.
In another embodiment, the rack assembly is provided with a power end, the power end drives the conveying screen assembly and the auxiliary soil-removing assembly to operate, the power end comprises a motor and a gearbox, and the motor outputs power through the gearbox to drive the conveying screen assembly B and the auxiliary soil-removing assembly C to operate.
As shown in fig. 11, when cyperus esculentus is harvested, the whole cyperus esculentus and a large amount of soil and other impurities are thrown to the conveying surface, namely the screen surface, of the conveying screen assembly, when the mixed material is conveyed from front to back, cyperus esculentus roots and large-particle impurities are located at the bottom layer of the mixed material and are tightly attached to the screen surface of the conveying screen assembly, the screen surface is easy to block, so that the soil removal rate is low, the cyperus esculentus roots and the large-particle impurities are repeatedly turned under the action of disturbance roller teeth of the auxiliary soil removal assembly, the screen surface is transparent, the soil removal rate is effectively improved, and the working pressure is reduced for subsequent bean picking and impurity removal devices.
The working principle of the invention is as follows: the transmission group drives the disturbing rollers and the disturbing roller teeth to rotate, the disturbing roller teeth on any adjacent disturbing rollers are crossed in the rotating process, impurities such as the whole cyperus esculentus and a large amount of soil are thrown to the screen surface of the conveying screen assembly, namely the conveying surface, and in the process of conveying the mixed material from front to back, cyperus esculentus roots and large-particle impurities are tightly attached to the screen surface of the conveying screen assembly if the cyperus esculentus roots and the large-particle impurities are positioned at the bottom layer of the mixed material, so that the screen surface is easy to block and the soil removal rate is low.
It should be noted that the motor, the gearbox, the cylinder and the electric push rod adopted in the present invention are all applications in the prior art, and those skilled in the art can implement the intended functions according to the related description, or implement the technical features required to be accomplished by similar techniques, and will not be described in detail herein.
