DETAILED DESCRIPTION

[0023] Please refer to Figures 1-6The embodiment of the application discloses a rice low-temperature conditioning device, which comprises a support stand 1, a mounting foot 2 arranged at the top of the support stand 1, and a wind-cooled conditioning assembly 3 arranged in the middle of the frame of the mounting foot 2, wherein the wind-cooled conditioning assembly 3 comprises a wind-cooled tank 31, a plurality of bearing sleeves 36 are arranged on the inner wall of the tank body of the wind-cooled tank 31 at equal intervals, the wind-cooled tank 31 is rotationally connected with a spiral propelling cylinder 37 through the bearing sleeves 36, a feeding pipe 32 is arranged at the top of the tank body of the wind-cooled tank 31, a discharge branch pipe 35 extending into the spiral propelling cylinder 37 is arranged at the discharge port of the feeding pipe 32 in a star-triangle form, a discharge pipe 33 communicating with the spiral propelling cylinder 37 is arranged at the bottom of the tank body of the wind-cooled tank 31, and the discharge pipe 33 is rotationally connected with the spiral propelling cylinder 37 through a first sealing shaft sleeve 319.

[0024] A spiral guide plate 38 is arranged on the inner wall of the spiral propelling cylinder 37, a conversion cylinder 39 is arranged at the center of the cylinder body of the spiral propelling cylinder 37, a spiral guide slot 310 is arranged on the outer wall of the conversion cylinder 39, a wind-cooled pipe 34 is arranged at the bottom of the tank body of the wind-cooled tank 31, an air outlet of the wind-cooled pipe 34 is connected with a wind guide pipe 321, the wind guide pipe 321 communicates with the discharge pipe 33 and the conversion cylinder 39, the wind guide pipe 321 is rotationally connected with the conversion cylinder 39 through a second sealing shaft sleeve 320, a plurality of wind-cooled holes 311 are arranged on the wall of the conversion cylinder 39 in a penetrating manner along the circumferential direction of the conversion cylinder 39, and the wind-cooled holes 311 are arranged in a ring-shaped symmetrical manner relative to the cylinder center of the conversion cylinder 39.

[0025] The top of the air cooling tank 31 is provided with a rotating transmission mechanism for driving the screw pushing cylinder 37 and the conversion cylinder 39, which includes a driving shell 312 installed on the top of the air cooling tank 31 and a transmission inner gear disc 318 installed on the upper cylinder port of the screw pushing cylinder 37. The driving shell 312 is a tripod structure, and the middle part of the support of the driving shell 312 is installed with a driving shaft 314. The top output end of the driving shaft 314 is connected with a driving motor 313, and the bottom output end of the driving shaft 314 is connected with the conversion cylinder 39. The middle output end of the driving shaft 314 is provided with a transmission gear 315. The outer side of the gear disc of the transmission gear 315 is meshed and connected with three groups of middle transmission gears 316 in a star triangle form. The middle transmission gears 316 are meshed and connected with the transmission inner gear disc 318 through a synchronous gear 317. The screw guide plates 38 and the screw guide grooves 310 are arranged in positive and reverse symmetry in the screw direction. In the process of cooling and conditioning the rice by using the conditioning device, the driving motor 313 works to drive the driving shaft 314 to rotate. The driving shaft 314 drives the conversion cylinder 39 to rotate on one hand, and drives the transmission gear 315 to rotate on the other hand. The transmission gear 315 drives the middle transmission gears 316 to rotate in the process of rotating, and then drives the transmission inner gear disc 318 to rotate through the meshing transmission of the middle transmission gears 316 and the synchronous gear 317. While the transmission inner gear disc 318 rotates, the screw pushing cylinder 37 rotates in the opposite direction relative to the conversion cylinder 39. Then, in the process of rotating of the conversion cylinder 39 and the screw pushing cylinder 37, the conversion cylinder 39 pushes the rice upward in a spiral direction through the screw guide grooves 310, and the screw pushing cylinder 37 pushes the rice upward in a spiral direction through the screw guide plates 38, which prolongs the flow length and residence time of the rice in the tank, and cools the rice physically.

[0026] The support stand 1 is symmetrically provided with two groups of guide rail frames 5 at the bottom end, and the track ends of the two groups of guide rail frames 5 are clamped with the hopper assembly 4 opposite to the discharge port of the air-cooled conditioning assembly 3. The hopper assembly 4 comprises a cart frame 41 guided by the two groups of guide rail frames 5, and the two sides of the cart frame 41 are provided with side supports 42. The front side of the side support 42 is provided with a push handle 43, and the inside of the frame of the side support 42 is provided with a hook mechanism. The hook end of the hook 49 in the hook mechanism is hung with a ton bag 410. The hook mechanism comprises a lifting lead screw 44 connected through the middle part of the frame of the side support 42 and a lifting guide rail 46 opened in the inner wall of the frame of the side support 42. The guide rail end of the lifting guide rail 46 is clamped with a lifting sliding table 47. The top of the shaft of the lifting lead screw 44 is provided with an adjusting hand wheel 48, and the outside of the shaft of the lifting lead screw 44 is provided with a lifting lead sleeve 45 fixedly connected with the lifting sliding table 47. The two ends of the frame of the lifting sliding table 47 are provided with hooks 49. The bottom of the cart frame 41 is symmetrically provided with pushing trolley wheels guided by the two groups of guide rail frames 5. After the rice is cooled, the rice is discharged into the ton bag 410. After the discharge is completed, the push handle 43 is pulled out of the ton bag 410 by using the guiding combination of the cart frame 41 and the guide rail frame 5. Then the adjusting hand wheel 48 is shaken to drive the lifting lead screw 44 to rotate. During the rotation of the lifting lead screw 44, the rotary force is converted into lifting thrust to drive the lifting lead sleeve 45 to displace upward and downward, thereby driving the lifting sliding table 47 to displace upward and downward. The hook 49 is moved downward to take out the lifting belt on the ton bag 410. Then the ton bag 410 is lifted and transported by using the lifting equipment.

[0027] The working principle of this invention is as follows: During the cooling and conditioning process of rice using the conditioning device, the rice to be cooled is fed into the inlet pipe 32. The rice is then discharged through the discharge pipe 35 into the spiral propulsion cylinder 37 for cooling. During this cooling and conditioning process, the drive motor 313 operates, driving the drive shaft 314 to rotate. The drive shaft 314 drives the conversion cylinder 39 to rotate on one hand, and the transmission gear 315 to rotate on the other. During rotation, the transmission gear 315 drives the intermediate gear 3... The 16 rotates, and then the meshing transmission of the central gear 316 and the synchronous gear 317 drives the internal gear disk 318 to rotate. While rotating, the internal gear disk 318 drives the screw propulsion cylinder 37 to rotate in the opposite direction relative to the conversion cylinder 39. During the rotation of the conversion cylinder 39 and the screw propulsion cylinder 37, the conversion cylinder 39 uses its screw guide groove 310 to push the rice screw upwards, and the screw propulsion cylinder 37 uses its screw guide plate 38 to push the rice screw upwards, extending the flow length and residence time of the rice in the tank, thus processing the rice. Physical cooling is employed, and simultaneously, a fan pump delivers cold air through the air-cooling pipe 34 to the air guide pipe 321. The cold air is then blown through the air guide pipe 321 into the conversion drum 39. Under air pressure, the cold air is blown out through the air-cooling exhaust holes 311 on the drum wall of the conversion drum 39, and then between the conversion drum 39 and the spiral propulsion drum 37, to cool the rice inside. The cooled hot air is then circulated out through the unloading branch pipe 35 and the unloading port 33. After further cooling of the rice, it is unloaded into a ton bag 410. After completion, using the guide combination of the trolley frame 41 and the guide rail frame 5, pull the pusher 43 to pull out the ton bag 410. Then, shake the adjusting handwheel 48 to drive the lifting screw 44 to rotate. During the rotation, the lifting screw 44 converts the rotational force into lifting thrust, pushing the lifting sleeve 45 to move up and down, and then pushing the lifting slide 47 to move up and down, moving the hook 49 down to facilitate the removal of the lifting straps on the ton bag 410. Then, use the lifting equipment to lift and transfer the rice in the ton bag 410 to complete its conditioning, cooling and transfer work.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
