[0005] In view of the problem that large grain drying machine generally occupies large area, and cannot be timely stored in warehouse to avoid wind and sun to prolong its service life when not in use, the utility model provides a kind of folding material lifting machine of grain drying machine.

[0006] To solve the above problems, the technical scheme adopted by the utility model is that,

[0007] The utility model provides a kind of grain dryer's folding material lifting machine, including shell, which is provided with conveying mechanism in shell, shell includes lower shell and upper shell;Upper shell is hinged on lower shell;Lower shell lower end is provided with inlet;Upper shell upper end is provided with discharge port;Conveying mechanism includes main cylinder;Main cylinder is connected with motor;Main cylinder is connected with driven cylinder by conveying belt;Driven cylinder is slidably arranged on lower shell;Main cylinder is rotatably arranged in upper shell.The height-adjustable and folding are realized by the hinge type shell design, which significantly improves the space utilization and transportation convenience, facilitates timely folding storage when not in use, reduces wind and sun exposure and prolongs service life, and also facilitates the towing of mobile operation;The sliding structure of driven cylinder can adjust the tension of conveying belt, and facilitate the smooth folding action.

[0008] Preferably, the upper end of the outer side of the lower shell is connected to the upper shell by a hinge; the outer side of the upper part of the lower shell is hinged with a telescopic drive; the end of the telescopic drive away from the lower shell is hinged to the upper shell. Through the action of the telescopic drive, the unfolding and folding action of the upper shell can be completed without manual operation, significantly improving the work efficiency; the telescopic drive and the hinge structure work together to adjust the height of the folding material lifting machine of the grain dryer, and the volume of the equipment is reduced in the folded state, facilitating transportation and site storage during mobile operation.

[0009] Preferably, a bracket is hinged to the outer side wall of the lower shell. The bracket can be unfolded or folded to form a triangular stable support structure, which provides support for the upper shell when it is folded, effectively disperses the weight of the upper shell and the load of the material, and avoids the risk of deformation or tipping of the shell under gravity in the folded state.

[0010] Preferably, a long hole is provided on the side wall of the lower shell to match the roll neck of the driven cylinder; a leakage prevention assembly is provided on the roll neck of the driven cylinder to match the long hole; the leakage prevention assembly is provided on the lower shell. The design of the leakage prevention assembly realizes the dual functions of dynamic sealing and tension adjustment of the conveying mechanism by being arranged between the long hole of the lower shell and the roll neck of the driven cylinder: the long hole allows the driven cylinder to slide along the lower shell to adjust the tension of the conveying belt, ensuring the realization of the folding action, and the leakage prevention assembly effectively blocks the leakage of material particles or dust from the long hole, ensuring the sealing and cleanliness of the conveying process,

[0011] Preferably, the leakage-proof assembly comprises a mounting seat; the roll neck of the driven roller is rotatably arranged on the mounting seat after penetrating the long slot; the mounting seat is slidably arranged between the two baffles; and the mounting seat is arranged outside the lower shell.

[0012] Preferably, a limiting plate is fixed between the upper portions of the two baffles; a sliding groove is arranged on the limiting plate; a sliding plate is slidably arranged in the sliding groove; and the lower end of the sliding plate is connected to the mounting seat. The limiting plate between the two baffles provides a guide for the movement of the mounting seat in cooperation with the sliding groove and the sliding plate. The sliding groove on the limiting plate limits the movement track of the sliding plate, thereby ensuring that the mounting seat can stably slide when adjusting the tension of the conveying belt or folding, avoiding deviation or jamming and improving the stability and reliability of the sliding of the driven roller. The lower end of the sliding plate is connected to the mounting seat, which not only strengthens the support structure of the mounting seat and enables it to withstand greater force during work, but also facilitates quick positioning and disassembly of the mounting seat through the sliding plate during equipment maintenance, greatly improving the maintenance efficiency. The arrangement of the sliding plate and the limiting plate can block the long slot to improve the sealing performance.

[0013] Preferably, a folding plate is fixedly arranged at each corner of the sliding plate; and the two folding plates on the upper portion of the sliding plate are arranged in the sliding groove. This arrangement ensures that the sliding plate can slide along the sliding groove of the limiting plate, avoiding deviation or jamming and improving the stability and reliability of the sliding of the driven roller.

[0014] Preferably, a lower baffle is fixedly arranged at the lower portion outside the mounting seat; and a blocking plate is arranged on the lower shell in cooperation with the lower baffle. The lower baffle can prevent the mounting seat from excessive displacement due to excessive force or abnormal conditions during sliding, and the blocking plate provides a reverse support for the lower baffle, further strengthening the constraint of the mounting seat and ensuring that the mounting seat always remains within a reasonable sliding range when the driven roller adjusts the tension of the conveying belt or folds, thereby avoiding the improper movement of the mounting seat affecting the normal operation of the conveying belt and ensuring the stable operation of the lifting machine conveying mechanism, reducing the probability of equipment failure and prolonging the overall service life of the equipment.

[0015] As can be seen from the above technical solutions, the advantages of the present application include: the height-adjustable and foldable design of the hinged shell significantly improves the space utilization and transportation convenience, facilitates timely folding and storage when not in use, reduces wind and sun exposure and prolongs the service life, and also facilitates drag operation during mobile operation; the sliding structure of the driven roller can adjust the tension of the conveying belt, facilitating the smoothness of the folding action.
