The specific unloading process includes: the limestone blocks of different sizes slide down through the inclined surface at the bottom of the transfer frame 3, the normal size limestone blocks are guided into the plurality of groups of material distribution cylinders 51, and the tapered cylinder 58 disperses and falls on the inclined surface, and the larger size limestone blocks are directly discharged outward through the opening of the transfer frame 3 and fall into the car body. And normal volume of limestone particles before the large volume of limestone fall, can fill in the gap between the large volume of limestone block, further improve the tightness and uniformity of the accumulation, the paving method can ensure the loading efficiency, and ensure the distribution of limestone block in the car is more reasonable; In the car bottom layer paving, with the continuous discharge of material in the distribution empty cylinder 51, start single shaft motor two 57, its drive one group of auxiliary gear 55 rotation, and under the meshing effect, auxiliary gear 55 then drive the adjacent main gear 56 synchronous rotation, thus, a number of groups of vertical rod 52 then traction corresponding cone cylinder 58 synchronous rotation, vertical rod 52 along the distribution empty cylinder 51 inside rotation and auxiliary accumulation loose down, cone cylinder 58 rotation is more conducive to the uniform dispersion of limestone block in the distribution empty cylinder 51 discharge; At the same time, the cone cylinder 58 rotation and drive a number of groups of scraper 59 rotation, and realize the rotation of the moderate volume of limestone particles in the car is scraped flat, and further increase the uniformity of limestone.

[0021] It is worth mentioning that, in the process of moving paving, when a number of groups of distribution empty cylinder 51 moves to the opening of the car side, then start the cylinder two 54, its use push rod traction movable plate 53 upward movement, and movable plate 53 then traction vertical rod 52 and corresponding cone cylinder 58 synchronous upward; Until the cone cylinder 58 is inserted into the distribution empty cylinder 51 inside, and the bottom of the cone cylinder 58 and the bottom of the distribution empty cylinder 51 cylinder mouth coincide to realize the sealing of the distribution empty cylinder 51, so as to avoid the waste of limestone block resources and affect the environmental sanitation of limestone block loading site when the limestone block is discharged to the area outside the car. At the same time, the coincidence of the cone cylinder 58 and the distribution empty cylinder 51 inside can further push and comb the jammed gravel in the distribution empty cylinder 51 inside, so as to reduce the jamming in the distribution empty cylinder 51 inside and affect the guide efficiency.

[0022] The structure is through the guide way of large particles directly falling and small particles grading and dispersing, which can not only improve the loading efficiency and uniformity, but also reduce the impact damage of stone to the inner wall of the car.
