[0002] A tunnel drying oven is a device used to dry materials containing moisture. When using a tunnel drying oven, the materials to be dried, such as medicinal herbs, are transported to the inside of a connecting frame via a conveyor belt. Heating rods evenly arranged inside the connecting frame raise the temperature inside the frame, thereby drying the materials inside. During the drying process, temperature detection devices are evenly arranged on the top of the connecting frame, and the measured temperature is displayed on a screen. This allows for effective monitoring of the temperature inside the connecting frame, facilitating the drying of the materials.

[0003] The inventors discovered in their daily work that tunnel drying ovens still have at least the following problems: When using a tunnel drying oven, the materials to be dried, such as medicinal herbs, are transported to the inside of the connecting frame via a conveyor belt. Heating rods evenly arranged inside the connecting frame raise the temperature inside, thereby drying the materials inside the connecting frame. During the drying process, temperature detection devices are evenly arranged on the top of the connecting frame, and the measured temperature is displayed on a screen. This allows for good monitoring of the temperature inside the connecting frame, which facilitates the drying of materials. However, in actual use, when placing the materials on the conveyor belt, the materials need to be spread out manually, which is quite troublesome during the drying process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tunnel drying oven capable of monitoring internal temperature.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tunnel drying oven capable of monitoring internal temperature, comprising a support frame, a first motor fixedly connected to one side of the support frame, a rotating roller fixedly connected to the output end of the first motor, the rotating roller being rotatably inserted into the inner wall of the top of the support frame, a conveyor belt sleeved on the surface of the rotating roller, a connecting frame fixedly connected to the top of the support frame, heating rods evenly arranged on the inner wall of the connecting frame, temperature detection devices evenly arranged on the top of the connecting frame, a display screen on one side of the temperature detection device, a limit device on one side of the connecting frame, a rotating device on the inner wall of the connecting frame, the limit device comprising a sliding plate, the sliding plate being slidably inserted through the top of the connecting frame, a round rod fixedly connected to the inner wall of the bottom of the sliding plate, a roller rotatably sleeved on the surface of the round rod, and a rectangular plate fixedly connected to the top of the sliding plate.

[0006] The effect achieved by the above components is as follows: when using the limiting device, the sliding plate is manually controlled to pass through the connecting frame to the appropriate position. After the material to be dried is placed on the conveyor belt, when the conveyor belt moves the material past the bottom of the sliding plate, the roller will be rotated, thereby preventing the material from accumulating in large quantities. This can prevent the material from accumulating to a certain extent.

[0007] Preferably, a sliding strip is fixedly connected to one side of the sliding plate, the sliding strip is slidably inserted through the top of the connecting frame, a limiting frame is fixedly connected to the top of the connecting frame, the limiting frame is slidably sleeved on one side of the sliding strip, and a first bolt is threaded through one side of the limiting frame.

[0008] The effect achieved by the above components is as follows: when the sliding plate slides to the appropriate position, the first bolt is manually controlled to rotate, thereby pressing the first bolt against one side of the sliding strip. This can effectively fix the sliding strip inside the connecting frame, and thus effectively fix the sliding plate inside the connecting frame.

[0009] Preferably, a rotating plate is hinged to the top of the support frame, and a fixing rod is fixedly connected to the side of the rotating plate near the connecting frame. A second bolt is threaded through the end of the fixing rod away from the rotating plate, and a round block is fixedly connected to the end of the second bolt away from the fixing rod.

[0010] The effect achieved by the above components is as follows: manually controlling the rotation of the rotating plate, and then manually controlling the rotation of the second bolt, so that the round block is pressed against one side of the connecting frame, which can effectively restrict the rotating plate to both sides of the conveyor belt, and thus effectively restrict the material to the surface of the conveyor belt.

[0011] Preferably, a circular arc groove is evenly provided on one side of the connecting frame, a rubber strip is fixedly connected to the inner wall of the circular arc groove, and the inner wall of the circular arc groove is slidably connected to the circular block.

[0012] The effect achieved by the above components is that when the round block approaches the connecting frame, the round block is pressed against one side of the rubber strip fixed inside the arc groove, which can effectively restrict the round block inside the arc groove, thereby effectively restricting the rotating plate to one side of the connecting frame.

[0013] Preferably, the rotating device includes a rotating cylinder, which is rotatably inserted into the inner wall of the connecting frame. A connecting frame is fixedly connected to one side of the connecting frame, and a second motor is fixedly connected to the inner wall of the connecting frame. The output end of the second motor is fixedly connected to one side of the first pulley, and the end of the first pulley away from the second motor is fixedly connected to one end of the rotating cylinder.

[0014] The effect achieved by the above components is as follows: when using the rotating device, the rotating drum is driven to rotate by the second motor. Because the surface of the rotating drum is evenly provided with triangular blocks, the material can be scooped up by the triangular blocks when the rotating drum rotates, and then the material can be turned over, so that the material can be dried to a certain extent.

[0015] Preferably, one end of the other rotating cylinder is fixedly connected to a second pulley, and the surfaces of the second pulley and the first pulley are fitted with connecting belts.

[0016] The effect achieved by the above components is that the connecting belt can drive the two rotating cylinders to rotate simultaneously in the same direction via the second motor.

[0017] Preferably, a slide rail is fixedly connected to one side of the connecting frame, a protective sleeve is slidably connected to the inner wall of the slide rail, the protective sleeve is fitted onto the surface of the connecting strip, and an air outlet groove is evenly opened on one side of the protective sleeve.

[0018] The effect achieved by the above components is as follows: the protective cover can be manually slid into the inside of the slide rail, so that the protective cover can cover the connecting belt, thereby preventing the passing operators from affecting the connection between the two rotating cylinders. The air outlet can effectively dissipate heat.

[0019] Preferably, a locking strip is slidably inserted through one side of the slide rail, a damping rod is fixedly connected to one side of the locking strip, the bottom of the damping rod is fixedly connected to the top of the slide rail, a spring is sleeved on the surface of the damping rod, one end of the spring is fixedly connected to the top of the slide rail, and the end of the spring near the damping rod is fixedly connected to one side of the locking strip.

[0020] The effect achieved by the above components is that by pulling the locking strip closer to the slide rail with the spring, the locking strip can be effectively restricted to one side of the protective sleeve, thereby effectively restricting the protective sleeve to the surface of the connecting strip.

[0021] In this invention, by setting a limiting device, when using the limiting device, the sliding plate is manually controlled to pass through the connecting frame to a suitable position. After the material to be dried is placed on the conveyor belt, when the conveyor belt moves the material past the bottom of the sliding plate, the roller will be driven to rotate, thereby preventing the material from accumulating in large quantities. This can prevent the material from accumulating to a certain extent. Attached Figure Description

[0027] Example 1, as Figure 1-4 As shown, a tunnel drying oven with internal temperature monitoring is described. A first motor 2 is fixedly connected to one side of a support frame 1. A rotating roller 3 is fixedly connected to the output end of the first motor 2. The rotating roller 3 is rotatably inserted into the inner wall of the top of the support frame 1. A conveyor belt 4 is fitted onto the surface of the rotating roller 3. A connecting frame 6 is fixedly connected to the top of the support frame 1. Heating rods 5 are evenly arranged on the inner wall of the connecting frame 6. Temperature detection devices 7 are evenly arranged on the top of the connecting frame 6. A display screen 10 is provided on one side of the temperature detection device 7. A limit device 8 is provided on one side of the connecting frame 6. A rotating device 9 is provided on the inner wall of the connecting frame 6. When using the tunnel drying oven, the material to be dried, such as medicinal materials, is conveyed to the interior of the connecting frame 6 by the conveyor belt 4. The heating rods 5 evenly arranged inside the connecting frame 6 raise the temperature inside the connecting frame 6, thereby drying the material inside the connecting frame 6. During the drying process, the temperature detection devices 7 are evenly arranged on the top of the connecting frame 6 and display the measured temperature on the display screen 10. This allows for effective monitoring of the temperature inside the connecting frame 6, facilitating the drying of the material.

[0028] Reference Figure 2 and Figure 3The limiting device 8 includes a sliding plate 801, which is slidably inserted through the top of the connecting frame 6. A round rod 802 is fixedly connected to the inner wall of the bottom of the sliding plate 801, and a roller 803 is rotatably sleeved on the surface of the round rod 802. A rectangular plate 804 is fixedly connected to the top of the sliding plate 801. When using the limiting device 8, the sliding plate 801 is manually controlled to pass through the connecting frame 6 to a suitable position. After the material to be dried is placed on the conveyor belt 4, when the conveyor belt 4 moves the material past the bottom of the sliding plate 801, the roller 803 will be driven to rotate, thereby preventing the material from being pushed aside. The material is piled up in large quantities, which can prevent the material from piling up to a certain extent. A sliding strip 806 is fixedly connected to one side of the sliding plate 801. The sliding strip 806 is slidably inserted through the top of the connecting frame 6. A limit frame 805 is fixedly connected to the top of the connecting frame 6. The limit frame 805 is slidably sleeved on one side of the sliding strip 806. A first bolt 807 is threaded through one side of the limit frame 805. When the sliding plate 801 slides to the appropriate position, the first bolt 807 is manually controlled to rotate, thereby pressing the first bolt 807 against one side of the sliding strip 806. This can effectively prevent the material from piling up. The sliding strip 806 is fixed inside the connecting frame 6, which in turn securely fixes the sliding plate 801 inside the connecting frame 6. A rotating plate 808 is hinged to the top of the support frame 1. A fixing rod 810 is fixedly connected to the side of the rotating plate 808 near the connecting frame 6. A second bolt 811 is threaded through the end of the fixing rod 810 away from the rotating plate 808. A round block 812 is fixedly connected to the end of the second bolt 811 away from the fixing rod 810. Manually controlling the rotation of the rotating plate 808, and consequently manually controlling the rotation of the second bolt 811, causes the round block 812 to press against one side of the connecting frame 6. This effectively confines the rotating plate 808 to both sides of the conveyor belt 4, thus effectively confining the material to the surface of the conveyor belt 4. A circular arc groove 809 is evenly distributed on one side of the connecting frame 6. A rubber strip 813 is fixedly connected to the inner wall of the circular arc groove 809. The inner wall of the circular arc groove 809 is slidably connected to the round block 812. When the round block 812 approaches the connecting frame 6, it presses against one side of the rubber strip 813 fixed inside the circular arc groove 809, effectively confining the round block 812 inside the circular arc groove 809, thereby effectively confining the rotating plate 808 to one side of the connecting frame 6.

[0029] Reference Figure 4The rotating device 9 includes a rotating cylinder 901, which is rotatably inserted into the inner wall of the connecting frame 6. A connecting frame 902 is fixedly connected to one side of the connecting frame 6, and a second motor 903 is fixedly connected to the inner wall of the connecting frame 902. The output end of the second motor 903 is fixedly connected to one side of the first pulley 904, and the end of the first pulley 904 away from the second motor 903 is fixedly connected to one end of the rotating cylinder 901. When the rotating device 9 is used, the second motor 903 drives the rotating cylinder 901 to rotate because the surface of the rotating cylinder 901... Evenly spaced triangular blocks allow the material to be scooped up and turned as the rotating drum 901 rotates, ensuring thorough drying. A second pulley 905 is fixedly connected to one end of the other rotating drum 901. A connecting belt 906 is fitted onto the surfaces of the second pulley 905 and the first pulley 904, enabling the second motor 903 to drive both rotating drums 901 to rotate simultaneously in the same direction. A slide rail 907 is fixedly connected to one side of the connecting frame 6. A protective sleeve 908 is slidably connected to the inner wall of slide rail 907. The protective sleeve 908 is fitted onto the surface of connecting belt 906. Air outlet slots 909 are evenly distributed on one side of the protective sleeve 908. The protective sleeve 908 is manually slid into the slide rail 907, thus covering the connecting belt 906 and preventing passing operators from affecting the connection between the two rotating cylinders 901. The air outlet slots 909 effectively dissipate heat. A locking strip 910 is slidably inserted through one side of slide rail 907, with one side of the locking strip 910 fixed. A damping rod 911 is connected, with its bottom fixedly connected to the top of the slide rail 907. A spring 912 is fitted onto the surface of the damping rod 911, with one end of the spring 912 fixedly connected to the top of the slide rail 907. The end of the spring 912 near the damping rod 911 is fixedly connected to one side of the locking strip 910. By pulling the locking strip 910 towards the slide rail 907 through the spring 912, the locking strip 910 can be effectively restricted to one side of the protective sleeve 908, thereby effectively restricting the protective sleeve 908 to the surface of the connecting strip 906.

[0030] Working principle: When using the tunnel drying oven, the material to be dried, such as medicinal herbs, is conveyed to the interior of the connecting frame 6 via the conveyor belt 4. Heating rods 5, evenly distributed inside the connecting frame 6, raise the temperature inside, thus drying the material. During the drying process, temperature detection devices 7 are evenly distributed on the top of the connecting frame 6, displaying the measured temperature on the display screen 10. This allows for effective monitoring of the temperature inside the connecting frame 6, facilitating material drying. When using the limit device 8, the sliding plate 801 is manually controlled to pass through the connecting frame 6 and reach the appropriate position. When the sliding plate 801 reaches the appropriate position, the limit device 801 is manually... Controlling the rotation of the first bolt 807 causes it to press against one side of the sliding strip 806, thus securing the sliding strip 806 inside the connecting frame 6. This, in turn, secures the sliding plate 801 inside the connecting frame 6. After the material to be dried is placed on the conveyor belt 4, as the conveyor belt 4 moves the material past the bottom of the sliding plate 801, the roller 803 will rotate. Manually controlling the rotation of the rotating plate 808, and consequently manually controlling the rotation of the second bolt 811, causes the round block 812 to press against one side of the connecting frame 6. When the round block 812 approaches the connecting frame 6, it is pressed into and fixed inside the arc groove 809. One side of the rubber strip 813 effectively confines the round block 812 within the arc groove 809, thereby effectively confining the rotating plate 808 to one side of the connecting frame 6. This effectively confines the rotating plate 808 to both sides of the conveyor belt 4, thus effectively confining the material to the surface of the conveyor belt 4 and preventing large-scale material accumulation. When using the rotating device 9, the second motor 903 drives the rotating drum 901 to rotate. Through the connecting belt 906, the second motor 903 drives both rotating drums 901 to rotate simultaneously in the same direction, because the surface of the rotating drum 901 is evenly equipped with triangular blocks. When the rotating drum 901 rotates, the material can be scooped up by the triangular block and then turned over, which allows the material to be dried to a certain extent. The protective cover 908 is manually slid into the slide rail 907, and the locking strip 910 is pulled towards the slide rail 907 by the spring 912. This can effectively restrict the locking strip 910 to one side of the protective cover 908, and thus effectively restrict the protective cover 908 to the surface of the connecting belt 906. This allows the protective cover 908 to cover the connecting belt 906, thus preventing the passing operators from affecting the connection between the two rotating drums 901. The air outlet slot 909 can effectively dissipate heat.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
