[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1-5 A short tube rice cooling device comprises a horizontal rice cooling part 1, a bracket 2 for carrying the horizontal rice cooling part 1, a temperature detector 3 and two swing mechanisms 4. The horizontal rice cooling part 1 comprises a left feeding circular shell 11, a right discharging circular shell 12, a connecting shaft 13 with two ends passing through the axis of the left feeding circular shell 11 and the right discharging circular shell 12, a spring 14 sleeved on the connecting shaft 13 and located between the left feeding circular shell 11 and the right discharging circular shell 12, and a movable tube group 15 connecting the opposite side walls of the left feeding circular shell 11 and the right discharging circular shell 12 and uniformly distributed in the circumferential direction. A feeding port and a discharging port are respectively arranged on the left feeding circular shell 11 and the right discharging circular shell 12 for rice loading and discharging after cooling. The movable tube group 15 consists of at least three short sections. The movable tube group 15 is composed of a tube 151 and a corrugated tube 152 located between adjacent short tube sections 151, so that the movable tube group 15 has the function of twisting action. The outer wall of the short tube section 151 is provided with evenly distributed ventilation holes 1511, and the ventilation holes 1511 are used for ventilation. The limiting plates 131 are fixedly arranged on the outer wall of the connecting shaft 13 and close to both ends. The two limiting plates 131 limit the sliding range of the left feeding circular shell 11 and the right discharging circular shell 12 on the connecting shaft 13. At the same time, the left feeding circular shell 11 and the right discharging circular shell 12 and the connecting shaft 13 are rotatably matched, which can be controlled by an external bolt locking structure. The two swing mechanisms 4 are correspondingly installed on the limiting plates 131 and are used in conjunction with the left feeding circular shell 11 and the right discharging circular shell 12 respectively.

[0041] A ring-shaped feeding outer conical cavity 111 is provided in the left feeding circular shell 11, and the large end of the feeding outer conical cavity 111 is close to and connected with the movable tube group 15. The feeding outer conical cavity 111 is used to hold rice in an initial state and has the function of guiding the rice into the movable tube group 15. A ring-shaped discharging inner conical cavity 121 is provided in the right discharging circular shell 12, and the small end of the discharging inner conical cavity 121 is close to and connected with the movable tube group 15. The right discharging circular shell 12 is used to hold cooled rice and has the function of guiding the rice in the movable tube group 15.

[0042] The temperature detector 3 is installed on the conical inclined surface of the feeding outer conical cavity 111 and the discharging inner conical cavity 121 to detect the temperature of the internal rice for easy detection and judgment;

[0043] Two support plates 21 are welded on the bracket 2 and penetrate and cooperate with both ends of the connecting shaft 13. A rotating motor 5 is installed on one side of one of the support plates 21. The output shaft of the rotating motor 5 is fixedly connected to one end of the connecting shaft 13. The rotating motor 5 drives the entire horizontal rice cooling part 1 to rotate, so that the rice in the feeding outer conical cavity 111 and the movable pipe group 15 flows into the discharging inner conical cavity 121, and the unloading is convenient.

[0044] The left feeding circular shell 11 and the right discharging circular shell 12 are both fixedly connected with eccentrically distributed shifting plates 6 on the opposite end surfaces, and a waist-shaped hole 61 is provided on the upper end surface of the shifting plate 6. The swing mechanism 4 is composed of a swing motor 41 and a driving plate 42 fixedly sleeved on its output shaft, and the top gap of the driving plate 42 passes through the waist-shaped hole 61.

[0045] The total volume of the inner cavities of the feeding outer conical cavity 111, the discharging inner conical cavity 121 and the evenly distributed movable tube group 15 are all the same, thereby preventing the occurrence of piled materials in the feeding outer conical cavity 111 and the movable tube group 15 when the rice is cooled;

[0046] A short tube rice cooling process in this case includes the following steps:

[0047] Step 1, feeding: the rice sorted by the color sorter is fed through the feeding port on the left feeding circular shell 11 by a belt conveyor. The capacity of the rice is 1 / 2 of the volume of the feeding outer conical cavity 111, which is convenient for the flow of rice and avoids the occurrence of piles;

[0048] Step 2: Cool rice:

[0049] a. Use a cooling fan to blow air to cool the horizontal rice cooling section 1 to accelerate the rice cooling process;

[0050] b. Start the swing motor 41 on one side of the left feeding circular shell 11 to do the swing motion, the swing angle is 180 degrees, the swing frequency is 15-30HZ, and the swing motor 41 on one side of the right discharging circular shell 12 is stopped at the same time, and the swing time is 25-35min. This process has the function of guiding the raw rice in the left feeding circular shell 11 into the movable pipe group 15, and the rice entering the inside of the movable pipe group 15 at the same time realizes circumferential tumbling and sliding in the direction of the right discharging circular shell 12 during the cooling process, thereby increasing the contact area with the cold air;

[0051] c. Start the swing motor 41 located at one side of the right discharging circular shell 12, and stop the swing motor 41 located at one side of the left feeding circular shell 11. The swing angle, swing time and swing frequency are the same as those in step b. As a result, the movable pipe group 15 undergoes a twisting motion. After the rice in the left feeding circular shell 11 completely enters the movable pipe group 15, the right discharging circular shell 12 moves, which can accelerate the flow of rice in the movable pipe group 15 into the right discharging circular shell 12.

[0052] Step 3: Discharging:

[0053] a. Start the rotary motor 5 to control the horizontal rice cooling unit 1 to rotate at a speed of 130-160 r / min, start the swing motor 41 located on one side of the right discharging circular shell 12, the swing angle is 180 degrees, and the swing frequency is 8-12 Hz, so that the cooled rice can enter the conical cavity 121 in the discharging;

[0054] b. Open the discharge port at the bottom of the right discharge circular shell 12 to discharge the material, and keep the rotating motor 5 and the swing motor 41 on one side of the right discharge circular shell 12 alternately started to achieve discharge.

[0055] Example 2

[0056] Based on Example 1, the difference is that a short tube rice cooling process comprises the following steps:

[0057] In step 2, after the temperature detector 3 detects that the temperature in the outer conical cavity 111 and the inner conical cavity 121 meets the standard, the operation in step c is performed, thereby avoiding the situation where the rice is not completely cooled.

[0058] The working principle of a short tube rice cooling device in this case is as follows: when in use, after the initial rice enters the outer conical cavity 111 of the left feeding circular shell 11, the swing motor 41 located on one side of the left feeding circular shell 11 is started, and the driving plate 42 toggles the paddle 6 to swing, the left feeding circular shell 11 swings, and the evenly distributed movable tube group 15 is twisted under the action of the bellows 152, the spring 14 is compressed, and the two ends of the spring 14 squeeze the left feeding circular shell 11 and the right discharging circular shell 12, which has a reset effect, and the outer conical cavity 11 of the feeding is reset. The initial rice in 11 begins to flow into the movable tube group 15 and tumbles, and heat is dissipated through the ventilation holes 1511 at this time. After all the initial rice enters the movable tube group 15, the swinging is stopped, and then another swing motor 41 is started to pull the rice in the movable tube group 15 and further dissipate heat. After entering the discharge inner conical cavity 121 in the right discharge circular shell 12, the rotating motor 5 and the swing motor 41 on one side of the right discharge circular shell 12 are kept started alternately, and the material is discharged through the discharge port.
