Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically a rice drying machine. Background Technology

[0002] Drying is a crucial step in rice processing. Drying rice effectively prevents it from becoming moldy and affecting its food safety. Therefore, to improve the efficiency of rice drying, appropriate dryers are usually used to process rice.

[0003] For example, a rice processing and drying device, such as the one disclosed in CN214307994U, includes a base, a support column, an outer casing, a drying basket, a hot air blower, an air diffuser, a motor, a stirring rod, and stirring blades. The support column is mounted on the base, the outer casing is mounted on the support column, the drying basket is located inside the outer casing, the hot air blower is mounted on the outer casing and extends into the outer casing, the air diffuser is mounted on the hot air blower, the motor is mounted on the outer casing, the stirring rod is mounted on the motor and rotates through the outer casing to extend into the outer casing, the stirring blades are mounted on the stirring rod, the drying basket includes a second motor, gears, a rice basket, and pulleys, the rice basket is rotatably mounted inside the outer casing, several sets of pulleys are symmetrically arranged, and all sets of pulleys are rotatably mounted on the rice basket, and an annular slide rail is provided inside the outer casing.

[0004] The existing technology has the following technical problems: When drying rice, the rice enters the device through the feed inlet. Since rice is in granular form, it is easy for the rice to become congested inside the feed inlet, which prevents the rice from quickly entering the machine for drying and reduces the overall drying efficiency of the dryer.

[0005] Therefore, we propose a rice drying machine to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a rice drying machine to solve the problem mentioned in the background art: in the current drying devices on the market, rice enters the device through the feed inlet. Since rice is in granular form, it is easy for the rice to become congested inside the feed inlet when it enters the device, which in turn prevents the rice from quickly entering the machine body for drying, thereby reducing the overall drying efficiency of the dryer.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rice drying machine, comprising a machine body, a feeding hopper installed at the upper end of the machine body, a discharging hopper installed at the lower end of the machine body, a control valve installed on the discharging hopper, an inner barrel installed inside the machine body, a heater installed between the inner barrel and the machine body, a servo motor installed at the lower end of the machine body, a stirring frame installed at the output end of the servo motor, a dredging component installed inside the feeding hopper, and a power adjustment component installed on the middle rod of the stirring frame.

[0008] Preferably, the inner barrel has multiple heat-conducting plates evenly distributed around its circumference, and the heat-conducting plates and the inner barrel are integrally formed, with one end of the heat-conducting plate located on the outside of the inner barrel and the other end located on the inside of the inner barrel.

[0009] By adopting the above technical solution and through the uniform distribution of the heat-conducting plates, the contact area between the outer wall of the inner barrel and the heat can be increased, thereby improving the heating effect.

[0010] Preferably, the middle rod of the stirring frame is provided with multiple stirring blades, and each stirring blade is provided with multiple branch plates that are perpendicular to it.

[0011] By adopting the above technical solution, the rice inside the inner bucket can be easily stirred by the rotation of the stirring blades and branch plates, so that the rice can be heated evenly.

[0012] Preferably, the unblocking component includes a central rod, a spiral spring, an unblocking rod, and a stop block. The central rod is installed in the middle of the feed hopper, a spiral spring providing a restoring force is installed on the central rod, and an unblocking rod is fixed circumferentially on the central rod. A stop block is fixed at the lower end of the central rod near the mixing frame.

[0013] By adopting the above technical solution and by setting up a spiral spring, the central rod can be reset and rebound after rotating inside the feed hopper.

[0014] Preferably, the central rod is rotatable in the middle of the feed hopper, and the central rod is provided with multiple unblocking rods.

[0015] By adopting the above technical solution, the rotation of the central rod inside the feeding hopper allows for easy unblocking of the rice inside the feeding hopper using the side branch plates.

[0016] Preferably, the power adjustment component includes an adjustment screw, which is threadedly connected to the middle rod of the stirring frame. A piston block is fixed to the lower end of the adjustment screw, and the piston block is located inside the air storage chamber. A connecting pipe is fixed to the side of the middle rod of the stirring frame, and a drive rod is installed through the middle of the connecting pipe. The drive rod is connected to the connecting pipe by a built-in spring.

[0017] By adopting the above technical solution, the piston block at its lower end can be moved inside the air storage chamber by adjusting the rotation of the lead screw.

[0018] Preferably, the piston block forms a seamless sliding connection structure with the air storage chamber through a circumferentially fixed sealing ring, and the air storage chamber and the connecting pipe are interconnected.

[0019] By adopting the above technical solution, when the piston block moves downward into the interior of the gas storage chamber, the airflow inside the gas storage chamber can be forced into the interior of the connecting pipe.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the rice drying machine can effectively clear the rice in the feed inlet when adding rice for drying, so as to avoid the rice from getting blocked inside the feed inlet and affecting the overall drying efficiency.

[0021] 1. It is equipped with a heat-conducting plate. The heat-conducting plate is evenly distributed around the inner barrel, which can increase the contact area between the outer wall of the inner barrel and the heat, thereby improving the heat absorption and heating effect of the inner barrel. At the same time, the inner end of the heat-conducting plate extends out of the inner barrel, which can also increase the contact area between the inner wall of the inner barrel and the rice.

[0022] 2. Equipped with a drive rod, the rotation of the mixing frame can drive the drive rod to rotate synchronously. The rotation of the drive rod can push the stop at the lower end of the central rod, so that the central rod reciprocates under the action of the spiral spring. The reciprocating rotation of the central rod and the unblocking rod can unblock the rice added into the feed hopper and prevent the rice from clogging inside the feed hopper.

[0023] 3. A piston block is provided. When the adjusting screw rotates, it drives the piston block to move upwards in the air storage chamber. This allows the airflow inside the connecting pipe to flow back into the air storage chamber. At this time, the drive rod is reset under the action of the built-in spring. After being reset, the drive rod cannot contact the stop block on the lower side of the center rod when it rotates with the stirring rack. This avoids the drive rod driving the unblocking component when rice is not needed in the subsequent drying process, thus reducing the load on the servo motor during drying.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: Please refer to Figures 1-6Existing drying devices dry rice by feeding rice into the device through an inlet. Since rice is granular, this can easily cause blockages inside the inlet, preventing it from quickly entering the machine body 1 for drying and reducing the overall drying efficiency. To address this problem, this embodiment discloses the following technical content: a rice drying machine, including a machine body 1, with a feed hopper 2 installed at the upper end of the machine body 1, and a feed hopper 2 installed at the lower end of the machine body 1. The machine body 1 has a discharge hopper 3 equipped with a control valve. An inner drum 4 is installed inside the machine body 1, and a heater 5 is installed between the inner drum 4 and the machine body 1. A servo motor 6 is installed at the lower end of the machine body 1, and a mixing frame 7 is installed at the output end of the servo motor 6. A clearing component 10 is installed inside the feed hopper 2, and a power adjustment component 11 is installed on the middle rod of the mixing frame 7. Multiple mixing blades are arranged on the side of the middle rod of the mixing frame 7, and each mixing blade has multiple branch plates 8 perpendicularly distributed thereto. The clearing component 10 includes a central rod 101. The feed hopper 2 is equipped with a spiral spring 102, a drain rod 103, and a stop block 104. A central rod 101 is installed in the middle of the feed hopper 2. A spiral spring 102 providing a return force is mounted on the central rod 101. A drain rod 103 is fixed circumferentially around the central rod 101. A stop block 104 is fixed at the lower end of the central rod 101 near the mixing frame 7. The central rod 101 can rotate in the middle of the feed hopper 2. Multiple drain rods 103 are provided on the central rod 101. The power adjustment component 11 includes an adjusting screw 111 with a threaded connection. A piston block 112 is fixed to the lower end of the adjusting screw 111 connected to the middle rod of the stirring frame 7, and the piston block 112 is located inside the air storage chamber 113. A connecting pipe 114 is fixed to the side of the middle rod of the stirring frame 7, and a drive rod 115 is installed through the middle of the connecting pipe 114. The drive rod 115 is connected to the connecting pipe 114 through the built-in spring 116. The piston block 112 forms a seamless sliding connection structure with the air storage chamber 113 through a circumferentially fixed sealing ring, and the interiors of the air storage chamber 113 and the connecting pipe 114 are interconnected.

[0033] When rice needs to be dried, the servo motor 6 is turned on. The servo motor 6 causes the stirring rack 7 to drive the drive rod 115 to rotate synchronously. When the drive rod 115 rotates and contacts the stop block 104 on the lower side of the center rod 101, it pushes the stop block 104 and the center rod 101 to rotate. When the drive rod 115 disengages from the stop block 104 as the stirring rack 7 rotates, the center rod 101 resets and reverses direction under the action of the spiral spring 102, thus achieving the reciprocating rotation of the center rod 101. The rotation of the central rod 101 drives the side unblocking rod 103 to rotate synchronously. At this time, the rice to be dried is added into the inner drum 4 through the feeding hopper 2. The reciprocating rotation of the central rod 101 and the unblocking rod 103 unblocks the rice inside the feeding hopper 2, preventing blockage. After adding the rice, the upper opening of the feeding hopper 2 is sealed. The adjusting screw 111 on the middle rod of the stirring frame 7 is rotated. Rotating the adjusting screw 111 causes the piston to... Block 112 moves above the air storage chamber 113. At this time, the airflow inside the connecting pipe 114 enters the air storage chamber 113. The drive rod 115 returns to its original position under the action of the built-in spring 116. After the drive rod 115 returns to its original position, it cannot contact the stop block 104 at the lower end of the center rod 101 during subsequent rotation. This avoids driving the unblocking component 10 when rice is not needed for subsequent drying, reducing the load on the servo motor 6 during drying and turning on the heater inside the machine body 1. 5. After the heater 5 is turned on, it can heat the inner barrel 4. The rice inside the inner barrel 4 is dried after the inner barrel 4 is heated. The rotation of the stirring rack 7 can drive the branch plate 8 on it to rotate synchronously. This can turn the rice in the inner barrel 4 during drying so that the rice can be heated evenly. After the rice is dried, the control valve on the discharge hopper 3 is opened to discharge the dried rice in the inner barrel 4. It should be noted that the centrifugal force generated by the rotation of the stirring rack 7 will not cause the drive rod 115 to move.

[0034] Example 2: The technical content disclosed in this example is a further improvement on the basis of Example 1 above. The technical content disclosed in this example is as follows: multiple heat-conducting plates 9 are evenly distributed around the inner barrel 4, and the heat-conducting plates 9 and the inner barrel 4 are integrally formed. One end of the heat-conducting plate 9 is located on the outside of the inner barrel 4, and the other end is located on the inside of the inner barrel 4.

[0035] The two ends of the heat-conducting plate 9 are located on the outer and inner sides of the inner barrel 4, respectively. By extending the heat-conducting plate 9 out of the outer side of the inner barrel 4, the contact area between the outer side of the inner barrel 4 and the heat can be increased, thereby improving the heating effect of the inner barrel 4. The inner end of the heat-conducting plate 9 extends into the inner side of the inner barrel 4, thereby increasing the contact area between the inner wall of the inner barrel 4 and the rice, thereby improving the drying effect of the rice.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
