[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0024] Please refer to Figures 1-6 The utility model provides an embodiment: an agricultural grain airing device, including granary 1, the lower portion of granary 1 is provided with material distributing cylinder 2, material distributing cylinder 2 is conically arranged, a plurality of material rings 21 are arranged on material distributing cylinder 2, a plurality of feeding ports 22 are formed in material ring 21, and the outer wall of material ring 21 and material distributing cylinder 2 is arranged to be inclined;Material distributing cylinder 2 is provided with material spreading mechanism 4 below, material spreading mechanism 4 includes connecting rod 405, the connecting rod 405 is connected with hopper 404, material spreading mechanism 4 further includes rotating shaft 42, and eccentric wheel 43 is fixedly connected on rotating shaft 42;Telescopic cylinder 44 is arranged between material distributing cylinder 2 and granary 1, spring 45 is arranged in telescopic cylinder 44, and eccentric wheel 43 cooperates with telescopic cylinder 44.
[0025] The setting of the distribution cylinder 2 can uniformly disperse the grain falling from the granary 1. After the grain falls from the granary 1, it first passes through the outer wall of the distribution cylinder 2 and then reaches the material ring 21. The material ring 21 stores a small amount of grain. Since the material ring 21 is provided with an inlet 22, and the material ring 21 and the distribution cylinder 2 are inclined, the stored grain will fall from the inlet 22, thereby dispersing the grain to all directions below the distribution cylinder 2. The plurality of material rings 21 have different diameters, thereby uniformly dispersing the grain in different areas, thereby achieving uniform dispersion of the grain and avoiding the accumulation of the grain, which affects the drying effect.
[0026] Please refer to Figure 2 The outer wall of the granary 1 is fixedly connected with a positioning block 46, and the positioning block 46 is slidingly connected with the telescopic end of the telescopic cylinder 44. The inlets 22 of the plurality of material rings 21 are not at the same vertical position, which can disperse the grain in different directions and make the grain more uniformly dispersed.
[0027] Please refer to the drawings, the shaft 42 and the granary 1 are connected through a mounting rod 47. The two ends of the shaft 42 are fixedly connected with a driving bevel gear 48. The driving bevel gear 48 is meshed with a driven bevel gear 49 below. The shaft 42 is provided with a transmission rod 401 below. The driven bevel gear 49 is fixedly connected to the transmission rod 401.
[0028] Please refer to Figures 2-3 The mounting rod 47 is provided with a motor 41. The output end of the motor 41 is fixedly connected with the shaft 42. The shaft 42 is provided with a mounting box 5 below. The transmission rod 401 extends into the mounting box 5 and is fixedly connected with a first bevel gear 402. A connecting rod 405 is rotatably connected in the mounting box 5. The connecting rod 405 is fixedly connected with a second bevel gear 403. The second bevel gear 403 is meshed with the first bevel gear 402.
[0029] Through the above technical scheme, the setting of the spreading mechanism 4 can not only drive the distribution cylinder 2 to vibrate, thereby causing the grain in the material ring 21 of the distribution cylinder 2 to fall, but also can avoid the blockage of the material ring 21. In addition, the spreading mechanism 4 can also drive the turnover bucket 404 to flatten the grain on the ground, thereby making the thickness of the grain on the ground consistent. In addition, the turnover bucket 404 can also turn over the grain, thereby enabling the lower layer of grain to be fully exposed to sunlight.
[0030] The action process of the spreading mechanism 4 is that firstly, the motor 41 is started, the motor 41 drives the rotating shaft 42 to rotate, the rotating shaft 42 further drives the two eccentric wheels 43 on it to rotate, the eccentric wheels 43 push the bottom of the distributing cylinder 2, the distributing cylinder 2 and the telescopic cylinder 44 move synchronously, the spring 45 in the telescopic cylinder 44 is compressed, so that the grains in the material ring 21 are shaken off, at the same time, the driving bevel gear 48 on the rotating shaft 42 rotates synchronously, with the rotation of the driving bevel gear 48, the driven bevel gear 49 meshing with it is driven to rotate, so as to drive the transmission rod 401 coaxially connected with it and the first bevel gear 402, since the first bevel gear 402 and the second bevel gear 403 are meshed, the second bevel gear 403 drives the connecting rod 405 connected with it to rotate, and finally drives the tipping bucket 404 to rotate.
[0031] Please refer to Figures 4-5 The barn 1 is provided with a speed regulating mechanism 3, the speed regulating mechanism 3 comprises a threaded sleeve 31, the threaded sleeve 31 is rotatably connected to the outlet of the barn 1, the threaded sleeve 31 is threadedly connected with the barn 1, a chute is formed in the threaded sleeve 31, and two symmetrically arranged L-shaped rods 32 are slidably connected in the chute, a conical body 33 is fixedly connected to the L-shaped rods 32, and the conical body 33 is located in the opening below the barn 1.
[0032] The speed regulating mechanism 3 can control the speed of the grains falling from the barn 1, and the specific adjustment process is that the threaded sleeve 31 is rotated, the threaded sleeve 31 moves on the barn 1, so that the L-shaped rods 32 slidably connected with the threaded sleeve 31 move synchronously, and finally the L-shaped rods 32 drive the conical body 33 to move in the outlet of the barn 1, the deeper the conical body 33 enters into the barn 1, the larger the area covered by the opening of the barn 1, and thus the slower the falling speed of the grains, and vice versa.
[0033] Please refer to Figure 1 Figure 1 An active slot matched with the L-shaped rods 32 is formed in the end of the distributing cylinder 2, a mounting frame 9 is fixedly connected to the outer wall of the barn 1, a hydraulic cylinder 6 is mounted at the end of the mounting frame 9 away from the barn 1, a connecting plate 7 is fixedly connected to the telescopic end of the hydraulic cylinder 6, universal wheels 8 are mounted at the two ends of the connecting plate 7, and the mounting frame 9, the hydraulic cylinder 6, the connecting plate 7 and the universal wheels 8 are arranged for moving the whole device.
[0034] Working principle: when in use, the grains are first loaded into the barn 1, at this time, the whole device is moved through the universal wheels 8, at this time, the grains fall from the barn 1, when the grains fall onto the distributing cylinder 2, the distributing cylinder 2 disperses the grains into different areas below the distributing cylinder 2, at the same time, the motor 41 is started, the motor 41 drives the eccentric wheels 43 to vibrate the distributing cylinder 2, so as to shake off the grains on the material ring 21, and drives the tipping bucket 404 to rotate, the tipping bucket 404 flattens and turns over the grains on the ground.
