Although this patent has the advantage of being able to stir the raw materials on the distillation mesh through a stirring roller, thereby improving the extraction efficiency of plant oils, the technical solution of this patent still has the following defects in actual use: Since this patent only uses a stirring roller to stir the raw materials, it does not have the function of crushing and cutting the raw materials. Since the raw materials are mostly plant flowers, leaves, roots, and bark, stirring alone cannot achieve sufficient distillation extraction. Furthermore, it does not have the function of re-extracting and circulating the raw materials remaining at the bottom after distillation extraction, which is not conducive to ensuring the full utilization of the raw materials. Moreover, it is not possible to easily remove, clean, and maintain the distillation mesh. Thus, it is difficult to guarantee the extraction effect and efficiency, resulting in poor distillation extraction effect and low efficiency. Utility Model Content

[0018] Please see Figure 3 and Figure 5A transmission assembly 11 is fixedly installed on the top of the top cover 8. The transmission assembly 11 includes a drive motor 113. The drive motor 113 is fixedly installed on the top of the top cover 8. The output shaft of the drive motor 113 and the surface of the hollow rotating shaft 102 are both fixedly connected to a second gear 111. The two second gears 111 are meshed together.

The other shaft end of the crushing roller 63 passes through the first bearing 62 and is fixedly connected to a worm 114. The worm gear 112 and the worm 114 are connected in a transmission manner. In this embodiment, under the action of the drive motor 113, the hollow shaft 102 is driven to rotate through the meshing connection of two second gears 111. The rotation of the hollow shaft 102 drives the worm gear 112 to rotate. Through the transmission action of the worm gear 112 and the worm 114, the worm 114 drives one of the crushing rollers 63 to rotate.

[0019] Please see Figure 2 and Figure 4 A distillation assembly 10 is fixedly installed on the top of the top cover 8. The distillation assembly 10 includes a second bearing 101, which is fixedly connected to the top of the top cover 8. A hollow shaft 102 is rotatably connected inside the second bearing 101. Multiple steam nozzles 105 are fixedly connected to the surface of the hollow shaft 102. An annular nozzle 104 is fixedly connected to one end of each steam nozzle 105.

Three third bearings 109 are fixedly connected to the surface of the hollow shaft 102. A third shaft 1010 is rotatably connected inside each of the three third bearings 109. A cutting blade 108 is fixedly connected to the surface of the third shaft 1010. A sliding groove 103 is opened on the top of the vessel body 3. A slider 106 is slidably connected inside the sliding groove 103. The slider 106 is fixedly connected to the side of the distillation mesh 107. In this embodiment, by setting a hollow rotating shaft 102, it can be connected to the steam pipe of an external steam device (this is a conventional technical means), which facilitates the delivery of high-temperature steam through the hollow rotating shaft 102 to the steam nozzle 105 and the annular nozzle 104, so as to achieve the purpose of distillation extraction of plants on the distillation mesh 107. The hollow rotating shaft 102 is made of high-temperature resistant material. At the same time, the rotation of the hollow rotating shaft 102 drives the steam nozzle 105 and the annular nozzle 104 to rotate, so as to achieve the purpose of uniform steam spraying, so that the steam and the plant raw materials can fully contact each other. During the rotation of the hollow rotating shaft 102, with the help of the friction between the cutting blade 108 and the plant raw materials on the distillation mesh 107, and through the rotation cooperation of the third rotating shaft 1010 in the third bearing 109, the cutting blade 108 rotates to stir and cut the plant raw materials, thereby improving the extraction efficiency and effect of the plant raw materials.

[0020] Please see Figure 3 and Figure 5 The top of the top cover 8 is fixedly connected to the feed frame 5. The feed frame 5 is equipped with a crushing component 6. The crushing component 6 includes two sets of first bearings 62. Crushing rollers 63 are rotatably connected in both sets of first bearings 62. One end of each crushing roller 63 passes through the first bearing 62 and is fixedly connected to a first gear 61. The two first gears 61 are meshed together. In this embodiment, under the transmission action of the worm gear 112 and worm 114 in the transmission assembly 11, the worm 114 rotates and drives a crushing roller 63 to rotate. With the help of the meshing rotation of the two first gears 61, the two crushing rollers 63 rotate inward synchronously, so as to achieve the purpose of preliminary crushing of plant raw materials during feeding and improve extraction efficiency.

[0021] Please see Figure 1 and Figure 2 A separation hopper 2 is fixedly connected to the bottom of the vessel body 3. A liquid outlet valve 9 is fixedly installed on the surface of the separation hopper 2. A circulation assembly 4 is fixedly installed between the bottom of the separation hopper 2 and the vessel body 3. The circulation assembly 4 includes a guide pipe 41, which is fixedly connected to the bottom of the separation hopper 2. A pump 42 is fixedly installed on the surface of the vessel body 3. The guide pipe 41 is fixedly connected to the pump 42. The outlet of the guide pipe 41 is fixedly connected to the surface of the vessel body 3.

[0022] In this embodiment, under the action of the pump 42, the raw material precipitated at the bottom of the separation hopper 2 can be pumped back to the distillation net 107 through the guide pipe 41 to achieve the effect of redistillation, improve resource utilization, ensure full extraction of plant raw materials, and facilitate the export, storage or use of the precipitated oil through the liquid outlet valve 9.

[0023] The working principle and usage process of this utility model are as follows: First, remove the top cover 8 and slide the slider 106 into the groove 103, so that the distillation mesh 107 and the steam nozzle 105 are located inside the vessel body 3 with the annular nozzle 104. Then, fix the top cover 8 and the vessel body 3 with bolts. At the same time, connect the steam pipe of the external steam equipment to the top of the hollow rotating shaft 102 through a rotary joint (the rotary joint is an existing product, which does not affect the steam delivery while cooperating with the rotation of the hollow rotating shaft 102), and complete the installation. Then, by controlling the drive motor 113 to work, the two second gears 111 mesh and rotate, which in turn causes the hollow shaft 102 to rotate, thereby driving the worm gear 112 and the worm 114. The rotation of the worm 114 drives a crushing roller 63 to rotate. With the help of the two first gears 61 meshing and rotating at the other end of the shaft, the two crushing rollers 63 rotate inward synchronously, feeding the plant raw materials into the feed frame 5. The crushing rollers 63 perform preliminary crushing of the plant raw materials, and the crushed raw materials enter the kettle body 3 and fall onto the distillation screen 107. Simultaneously, the hollow rotating shaft 102 rotates, driving the steam nozzle 105 and the annular nozzle 104 to rotate. The steam is evenly sprayed onto the distillation mesh 107, making full contact with the plant material for distillation. At the same time, the rotation of the hollow rotating shaft 102 drives the cutting blade 108 to rotate. With the help of the contact friction between the cutting blade 108 and the plant material, and through the rotation of the third rotating shaft 1010 in the third bearing 109, a certain degree of rotation is formed to stir the plant material while cutting it again, thereby improving the distillation extraction efficiency. Secondly, the distilled oil is separated by the separation hopper 2 and discharged by the liquid outlet valve 9. At the same time, the plant material settled at the bottom of the separation hopper 2 can be transported again to the distillation net 107 through the feed pipe 41 by the control of the feed pump 42 to redistill, thereby improving the utilization rate of the plant material. The steam is discharged through the exhaust pipe 7. Finally, the oil-water mixture and oil-vapor mixture discharged from the outlet valve 9 and the exhaust pipe 7 can be connected to the existing filtration equipment and condensation equipment through external pipes for further processing. The filtration equipment can separate the oil and water in the oil-water mixture to extract the oil. The condensation equipment can cool the oil-vapor mixture to extract the oil. After a period of use, the bolts can be unscrewed, the top cover 8 can be lifted upwards to separate the slider 106 from the slide groove 103, and the distillation mesh 107 and steam nozzle 105 can be taken out for cleaning to ensure the next use.

[0024] In the above scheme, it should be noted that the distillation apparatus in this application can also be equipped with an existing controller (or control system), and the operating status of the drive motor 113, the feed pump 42 and the liquid outlet valve 9 can be adjusted by using the existing mature controller (or control system) to realize the distillation extraction of oil from plant raw materials. Meanwhile, the telecommunication connection method, circuit layout method and control principle between the controller (or control system) and the drive motor 113, the pump 42 and the outlet valve 9 are all existing publicly available technical means, and do not involve any improvement to the computer program. Conventional and mature controllers (or control systems) in this field can be used for operation, and will not be described in detail here.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
