DETAILED DESCRIPTION

[0025] In order to make the technical scheme of the utility model more clear, the following will briefly introduce the drawings needed to be used in the description, obviously, the drawings in the following description are only some embodiments of the utility model, and for the ordinary skilled in the art, other drawings can be obtained according to these drawings without creative labor.

[0026] As Figure 1 andFigure 2 As shown, a grain dryer convenient to fold, comprising a frame 1, a hot air device 2 is installed at the front of the frame 1, the hot air device 2 is connected to a granary 3 installed in the middle of the frame 1 through a pipeline 5, a lifting machine 4 for conveying grain to the granary 3 is installed at the rear of the frame 1, and the granary 3 is provided with telescopic function; the lifting machine 4 comprises a mounting part 401, a hinged part 402 and a conveying mechanism installed in the mounting part and the hinged part; the mounting part is installed on the frame 1; the hinged part is hinged to the mounting part; and the hinge of the hinged part and the mounting part is located at the end of the lifting machine 4 away from the granary 3.

[0027] The telescopic granary 3 can greatly reduce the overall volume, and is convenient to carry and store. The rear lifting machine 4 is fixed on the frame 1 by the mounting part 401, the hinged part 402 is hinged to the mounting part 401 and the hinge is located at the end away from the granary 3, so that the hinged part 402 of the lifting machine 4 can rotate around the mounting part 401, and can rotate and fold around the hinge during folding, which greatly improves the convenience of folding the whole grain dryer, and is beneficial to reducing the overall volume, effectively solves the problems of difficult transportation and large storage space occupation of traditional dryers due to difficulty in folding, and improves the advantages of the equipment in space utilization and flexible deployment.

[0028] In the above arrangement, the lower end of the mounting part 401 is provided with a feeding port 403; the upper end of the hinged part 402 is provided with a discharging port 404; the mounting part 401 and the hinged part 402 are hinged through a folding leaf 405; and the folding leaf 405 is located at the end of the lifting machine 4 away from the granary 3. The conveying mechanism comprises a main roller 406; the main roller 406 is connected with a motor 407; the main roller 406 is connected with a driven roller 408 through a conveying belt; the driven roller 408 is slidingly arranged on the mounting part 401; and the main roller 406 is rotatably arranged in the hinged part 402. A telescopic driving member 409 is hinged to the hinged part 402 at the end away from the mounting part 401; and a bracket 410 is hinged to the outer side wall of the mounting part 401. The telescopic driving member 409 is an oil cylinder, a gas cylinder or an electric push rod. A sliding groove 411 is formed in the side wall of the mounting part 401 in cooperation with the roller neck of the driven roller 408.

[0029] When the grain dryer is in operation, the grain enters the elevator 4 from the inlet 403 at the lower end of the mounting portion 401. The motor 407 drives the main roller 406 to rotate, and the main roller 406 drives the driven roller 408 to rotate through the conveying belt, so as to realize the downward conveying of the grain in the elevator 4, and finally the grain is sent out from the outlet 404 at the upper end of the hinged portion 402 to the granary 3. When it is necessary to adjust the state of the elevator 4, if it is required to deploy the elevator 4 for work, the telescopic driving member 409 (such as an oil cylinder, an air cylinder or an electric push rod) is started to make it elongate, and the hinged portion 402 is driven to rotate around the hinge 405, and the support 410 hinged to the outer side wall of the mounting portion 401 is deployed to support, so as to ensure the stability of the elevator 4. Conversely, if the elevator 4 needs to be folded, the telescopic driving member 409 is controlled to be shortened, the hinged portion 402 is rotated around the hinge 405 to be folded, and the driven roller 408 is correspondingly slid on the mounting portion 401 to adapt to the folding of the elevator 4. In this process, since the hinge 405 is located away from the granary 3, the rotation and folding of the elevator 4 are more smooth, and interference with the granary 3 and other components is avoided. The mounting portion 401 and the hinged portion 402 are hinged through the hinge 405 located away from the granary 3, and the reasonable arrangement of the inlet 403 and the outlet 404 ensures the smoothness of the grain conveying path and provides a basis for the flexible folding of the elevator, which greatly improves the convenience of folding the equipment. The main roller 406 in the conveying mechanism is driven by the motor 407, which has strong power and drives the driven roller 408 through the conveying belt, so as to ensure the efficient and stable conveying of the grain, and the driven roller 408 is slidable on the mounting portion 401, so that the components in the elevator 4 do not hinder each other when the elevator 4 is folded, and the adaptability of the whole equipment is improved. The telescopic driving member 409 can accurately control the rotation angle of the hinged portion 402, which is convenient for adjusting the state of the elevator 4 under different working conditions, and the support 410 enhances the stability of the elevator 4 during work.

The movable storehouse bodies are provided with two, which are a middle storehouse body 304 and a top storehouse body 305; the top storehouse body 305 is sleeved in the middle storehouse body 304; the middle storehouse body 304 is sleeved in the fixed storehouse body 301; the plurality of movable rods comprise a middle sleeve pipe 309 and a top sleeve rod 310; the top sleeve rod 310 is connected with the outer wall of the top storehouse body 305; the middle sleeve pipe 309 is connected with the outer wall of the middle storehouse body 304; the top sleeve rod 310 is connected with the lifting driving mechanism.

[0031] In use of the grain storehouse 3 of the grain dryer, the hot air device 2 is started first, and the hot air is delivered to the hot air chamber 302 at the bottom of the fixed storehouse body 301 through the pipeline 5. The lifting driving mechanism drives the top sleeve rod 310 to rise, and the top sleeve rod 310 drives the top storehouse body 305 to rise; when rising to a certain height, the middle sleeve pipe 309 rises under the action of the lifting driving mechanism, and drives the middle storehouse body 304 to rise, so that the volume of the grain storehouse 3 is increased, and the grain can be fed into the storehouse from the top through the lifting machine 4 and the like. During the drying process, the hot air flows upwards from the hot air chamber 302 to dry the grain in the storehouse. After the drying is completed, if the grain storehouse 3 needs to be folded, the lifting driving mechanism is controlled to make the top sleeve rod 310 descend, and the top storehouse body 305 descends and is shrunk into the middle storehouse body 304, and then the middle sleeve pipe 309 descends, and the middle storehouse body 304 is shrunk into the fixed storehouse body 301, so that the overall volume of the grain storehouse 3 is reduced, and the equipment is convenient to carry or store. The hot air chamber 302 is mounted at the bottom of the fixed storehouse body 301 and connected with the hot air device through the pipeline 5, so that the hot air can enter the storehouse uniformly and efficiently, and a stable and suitable environment is provided for the grain drying, and the drying effect is ensured. The middle storehouse body 304 and the top storehouse body 305 are sleeved in the fixed storehouse body 301, and are connected through the telescopic rods evenly arranged on the outside of the fixed storehouse body 301 in the circumferential direction, so that the folding of the grain storehouse is stable. The fixed pipe 303 of the telescopic rod is fixed on the vehicle frame 1, the movable rods are slidably arranged in the fixed pipe 303 and connected with the lifting driving mechanism, so that the lifting of the movable storehouse bodies can be accurately controlled, and the telescopic function of the grain storehouse 3 is realized. When folding is needed, the volume of the grain storehouse 3 can be greatly reduced, the equipment is convenient to carry and store, and the space utilization rate is improved.

[0032] The outer wall of the fixed tube 303 is provided with a long slot 3031; the lower end of the top sleeve rod 310 is fixedly provided with a supporting rod 3101 in the radial direction; the supporting rod 3101 is arranged below the middle sleeve 309 and is arranged in the long slot 3031; and the supporting rod 3101 is connected with the rope 308. The lifting driving mechanism drives the rope 308 to move, and the supporting rod 3101 connected with the rope 308 slides in the long slot 3031 of the outer wall of the fixed tube 303. Since the supporting rod 3101 is fixed to the lower end of the top sleeve rod 310 and is arranged below the middle sleeve 309, the top sleeve rod 310 is driven to ascend and descend along the fixed tube 303, thereby driving the top bin body 305 to ascend or descend. When the top bin body 305 descends, the supporting rod 3101 slides downward with the top sleeve rod 310 and moves smoothly in the long slot 3031, ensuring that the top bin body 305 is retracted into the middle bin body 304, and then the two are retracted into the fixed bin body 301; when ascending, the supporting rod 3101 moves upward along the long slot 3031 under the pull of the rope 308, so that the top bin body 305 ascends stably. The cooperation of the long slot 3031 and the supporting rod 3101 provides guidance for the ascent and descent of the top sleeve rod 310, ensures the smoothness and non-deviation of the top bin body 305 during the ascent and descent process, and improves the stability of the entire grain bin 3.

[0033] As shown in Figure 4 and Figure 5 , the lifting driving mechanism includes a winding drum 306 rotatably arranged on the frame 1; the winding drum 306 is connected with a winding driving assembly 307; the winding drum 306 is connected with a rope 308; one end of the rope 308 away from the winding drum 306 is connected with the top sleeve rod 310 after passing through a pulley 312; and the pulley 312 is fixedly arranged on the upper portion of the outer wall of the fixed tube 303. The rope 308 connected with the telescopic rod far away from the winding drum 306 is connected with the supporting rod 3101 after passing through a guide wheel 311 and then passing through the pulley 312. The winding driving assembly includes a gear arranged on the rotating shaft of the winding drum 306 and a turbine meshing with the gear, which drives the winding drum 306 to rotate by rotating the turbine. In other alternative embodiments, the winding driving assembly is a motor.

[0034] Through the cooperation of the winding drum 306, the winding driving assembly, the rope 308, the pulley 312 and the guide wheel 311, stable driving of the top sleeve rod 310 is realized, and the ascent and descent of the top bin body 305 are accurately controlled. The pulley 312 is fixed on the upper portion of the outer wall of the fixed tube 303, which reasonably changes the direction of the pulling force of the rope 308, so that the driving process is smoother. The arrangement of the guide wheel 311 solves the problem of the direction of the rope 308 far away from the winding drum 306, ensuring that each telescopic rod can effectively receive driving force. The whole system structure is compact, and can accurately and efficiently realize the telescopic function of the grain bin. When the grain bin needs to be retracted, the volume of the grain bin can be effectively reduced, which is convenient for carrying and storing.
