Technical Field
[0001] This utility model belongs to the field of rice technology, specifically relating to a rice cooling device for a rice polishing machine. Background Technology
[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. The germ and aleurone layer of paddy contain nearly 64% of the rice's nutrients and more than 90% of the nutrients needed by the human body. It is a staple food for people in the south. Cooling rice is an important step in rice processing. It is usually done after wiping the rice to lower its temperature. Its purpose is to remove the bran and excess moisture from the white rice. In particular, the excess moisture and temperature in the rice after milling with water are released through the cooling process, which is beneficial for the storage, transportation, and preservation of the finished grain.
[0003] Existing rice cooling devices work by continuously turning the rice through a drive structure, stirring blades, and stirring rods to dissipate heat from the rice. However, relying solely on stirring for cooling is time-consuming and insufficient, severely impacting rice quality. Furthermore, the device cannot adjust the size of the feed inlet, reducing its efficiency in cooling the rice. Therefore, we provide a rice cooling device for a rice polishing machine. Utility Model Content
[0004] The purpose of this utility model is to provide a rice cooling device for a rice polishing machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice cooling device for a rice polishing machine, comprising a rice cooling box, a motor fixedly installed on the left side of the rice cooling box, a rotating rod fixedly connected to the output end of the motor and located inside the rice cooling box, a stirring blade fixedly connected to the surface of the rotating rod, a fan fixedly installed at the bottom right side of the rice cooling box, an air inlet pipe fixedly connected to the input end of the fan, an air guide pipe fixedly connected to the output end of the fan, a set of five air outlet hoods provided on the surface of the air guide pipe and located inside the rice cooling box, two movable shafts fixedly connected to the top of the inner cavity of the rice cooling box, an adjusting plate hinged to the two movable shafts, a sliding groove provided on the adjusting plate, electric telescopic rods fixedly connected to the top of both sides of the inner cavity of the rice cooling box, a first movable shaft fixedly connected to one end of the electric telescopic rod, a connecting rod hinged to the first movable shaft, and one end of the connecting rod slidably connected to the inner wall of the sliding groove on the adjusting plate.
[0006] Using the above scheme, the electric telescopic rod drives the first movable shaft to move to one side. The angle of the adjusting plate is changed by the cooperation of the connecting rod and the second movable shaft, thereby adjusting the size of the feed inlet to achieve quantitative feeding. Next, the motor drives the rotating rod to rotate, which in turn drives the stirring blade to rotate. The stirring blade stirs the rice. During the stirring process, the fan, in cooperation with the air inlet pipe, draws in external air, which is then delivered to the air guide pipe through the air inlet pipe and output through the air outlet hood. As the air rises, it cools the rice and carries the heat generated by the stirring upwards until the air containing heat is output through the heat dissipation holes on both sides of the top of the rice cooling box, greatly improving the efficiency of rice cooling.
[0007] In a preferred embodiment of the rice cooling device of a rice polishing machine, a guide plate is fixedly connected to the bottom of the inner cavity of the rice cooling box, and the top of the guide plate is inclined.
[0008] By adopting the above solution, the top of the guide plate is inclined, which can quickly output rice from the inside of the rice cooling box, achieving the purpose of efficient discharge.
[0009] In a preferred embodiment of the rice cooling device of a rice polishing machine, one end of the rotating rod is movably connected to a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the rice cooling box.
[0010] By adopting the above solution and setting the bearing, wear at one end of the rotating rod is reduced, preventing the rotating rod from jamming due to severe wear, and greatly improving the smoothness of the rotating rod's operation.
[0011] In a preferred embodiment of the rice cooling device of a rice polishing machine, a power supply box is fixedly connected to the top left side of the rice cooling box, and a storage battery is provided inside the power supply box.
[0012] By adopting the above solution, the electrical equipment is powered by a storage battery to maintain its normal operation.
[0013] In a preferred embodiment of the rice cooling device of a rice polishing machine, the surface of the rice cooling box is movably connected to a box door via a hinge, and a handle is fixedly connected to one side of the box door surface.
[0014] By adopting the above solution, the box door can be opened by the handle, and the inner cavity of the rice cooling box can be cleaned regularly using cleaning tools, which greatly improves the cleanliness of the inner cavity of the rice cooling box.
[0015] In a preferred embodiment of the rice cooling device of a rice polishing machine, heat dissipation holes are provided on both sides of the top of the rice cooling box, and a feed inlet is provided at the center of the top of the rice cooling box.
[0016] By adopting the above solution, the heat generated during the cooling process is dissipated through the heat dissipation holes, preventing heat accumulation.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This utility model uses a motor to drive a rotating rod to rotate, which in turn drives a stirring blade to rotate. The stirring blade stirs the rice. During the stirring process, a fan, in conjunction with an air inlet pipe, draws in external air, which is then transported to a duct pipe and output through an air outlet hood. As the air rises, it cools the rice and carries away the heat generated by the stirring process until the heated airflow is output through the heat dissipation holes on both sides of the top of the rice cooling box, greatly improving the efficiency of rice cooling.
[0019] 2. This utility model uses an electric telescopic rod to move the first movable shaft to one side. The angle of the adjusting plate is changed by the cooperation of the first movable shaft, the connecting rod, and the second movable shaft, thereby adjusting the size of the feed inlet and achieving the purpose of quantitative feeding.

[0024] Please see Figure 1-3 A rice cooling device for a rice polishing machine, comprising a rice cooling box 1, see Figure 3As shown, a guide plate 5 is fixedly connected to the bottom of the inner cavity of the rice cooling box 1. The top of the guide plate 5 is inclined, which allows rice to be quickly discharged from the inside of the rice cooling box 1, achieving efficient discharge. A motor 2 is fixedly installed on the left side of the rice cooling box 1. A rotating rod 3 is fixedly connected to the output end of the motor 2, located inside the inner cavity of the rice cooling box 1. A stirring blade 4 is fixedly connected to the surface of the rotating rod 3. A fan 6 is fixedly installed at the bottom of the right side of the rice cooling box 1. An air inlet pipe 9 is fixedly connected to the input end of the fan 6, and an air guide pipe 7 is fixedly connected to the output end of the fan 6. A set of five air outlet hoods 8 are installed on the surface of the air duct 7 and inside the rice cooling box 1. Two movable shafts 12 are fixedly connected to both sides of the top of the inner cavity of the rice cooling box 1. Adjusting plates 13 are hinged to the two movable shafts 12, and sliding grooves are provided on the adjusting plates 13. Electric telescopic rods 10 are fixedly connected to the top of both sides of the inner cavity of the rice cooling box 1. One end of the electric telescopic rod 10 is fixedly connected to a movable shaft 11. A connecting rod is hinged to the movable shaft 11, and one end of the connecting rod is slidably connected to the inner wall of the sliding groove on the adjusting plate 13. Figure 1 As shown, heat dissipation holes are provided on both sides of the top of the rice cooling box 1, and a feeding port is provided at the center of the top of the rice cooling box 1. The heat dissipation holes are designed to dissipate the heat generated during the rice cooling process and prevent heat accumulation. The electric telescopic rod 10 drives the first movable shaft 11 to move to one side. The first movable shaft 11, in cooperation with the connecting rod and the second movable shaft 12, changes the angle of the adjusting plate 13, thereby adjusting the size of the feeding port to achieve the purpose of quantitative feeding. Next, the motor 2 drives the rotating rod 3 to rotate, and the rotating rod 3 drives the stirring blade 4 to rotate. The stirring blade 4 stirs the rice. During the stirring process, the fan 6, in cooperation with the air inlet pipe 9, draws in external air, delivers the air to the air guide pipe 7 through the air inlet pipe 9, and outputs the airflow through the air outlet hood 8. As the airflow rises, it cools the rice and drives the heat generated by stirring to rise until the airflow containing heat is output through the heat dissipation holes on both sides of the top of the rice cooling box 1, which greatly improves the efficiency of rice cooling.
[0025] See Figure 3 As shown, a bearing is movably connected to one end of the rotating rod 3, and one side of the bearing is fixedly connected to one side of the inner cavity of the rice cooling box 1. The bearing reduces wear on one end of the rotating rod 3, preventing jamming due to severe wear, and greatly improving the smoothness of the rotating rod 3's operation. Figure 1 As shown, a power supply box is fixedly connected to the top left side of the rice cooling box 1, and the inner cavity of the power supply box is equipped with a storage battery. The storage battery provides power to the electrical equipment, maintaining its normal operation. Figure 1As shown, the surface of the rice cooling box 1 is movably connected to the box door via a hinge, and a handle is fixedly connected to one side of the box door surface. The box door is opened by the handle, and the inner cavity of the rice cooling box 1 is cleaned regularly using cleaning tools, which greatly improves the cleanliness of the inner cavity of the rice cooling box 1.
[0026] In use, rice is first conveyed through an external conveying mechanism from the feed inlet at the top of the rice cooling box 1 to its inner cavity. During the conveying process, the electric telescopic rod 10 drives the first movable shaft 11 to move to one side. The first movable shaft 11, in cooperation with the connecting rod and the second movable shaft 12, changes the angle of the adjusting plate 13, thereby adjusting the size of the feed inlet to achieve quantitative feeding. Then, the motor 2 drives the rotating rod 3 to rotate, which in turn drives the stirring blade 4 to rotate, stirring the rice. During the stirring process, the fan 6, in cooperation with the air inlet pipe 9, draws in external air, which is then delivered to the air guide pipe 7 through the air inlet pipe 9 and output through the air outlet hood 8. As the air rises, it cools the rice and causes the heat generated by stirring to rise until the hot air is output through the heat dissipation holes on both sides of the top of the rice cooling box 1, greatly improving the efficiency of rice cooling.
