Agricultural walnut shelling device

An agricultural walnut shelling device comprises a transporting device, a discharging device, a transporting crushing device, a secondary crushing device and a winnowing device. By arrangement of a plurality of crushing conveying belts tensioned through tensioning devices, multiple walnuts conveyed on the conveying belts can be crushed at the same time and are crushed while rolling forwards underthe simultaneous actions of a forward transporting force of the vertical and lower conveying belts and mutual pressing force of the upper and lower conveying belts, and accordingly pressure uniformityof the whole walnuts is realized, uniformity in crushing of the whole walnuts is realized as well, and nonuniformity in crushing due to nonuniform stress is avoided. By adjustment of stretching rods,adjustment rods can be adjusted to further adjust tensioning degrees of tension wheels, and accordingly pressure of the upper and lower conveying belts can be adjusted, and the walnut crushing degreecan be adjusted through pre
