[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0018] Please see Figure 1 and Figure 2 This utility model provides a grinding device for extracting plant essential oils, including a housing 1. A feeding hopper 3 is provided on one side of the top of the housing 1, extending into its interior. Several sliding grooves 11 are provided on the outer wall of the housing 1, and a guide module 6 is inserted into the interior of the sliding grooves 11.

[0019] In this embodiment, according to the prior art of the grinding device for extracting plant essential oils, the lower part of the shell 1 may also be provided with a filter and screening component and an external structure for circulating feeding (not shown in the figure), and the plant raw materials to be ground are added into the inside of the material frame 5 through the feed hopper 3.

[0020] Please see Figure 2 and Figure 3A drive module 2 is fixedly installed in the upper middle part of the housing 1. The drive module 2 is used to drive the grinding disc 4 to rotate inside the material frame 5. The drive module 2 includes a motor frame 21 fixed on the top outer wall of the housing 1, and a drive motor 22 is fixedly installed above the motor frame 21. A coupling 23 is connected to the lower output end of the drive motor 22, and a connecting shaft 24 inserted into the housing 1 is fixedly connected to the bottom of the coupling 23.

[0021] In this embodiment, the start drive module 2 can drive the grinding disc 4 to rotate inside the material frame 5 to achieve grinding and processing of plant raw materials. The start drive motor 22 can drive the connecting shaft 24 to rotate through the coupling 23. A bearing seat supporting the connecting shaft 24 is provided on the top of the housing 1.

[0022] Please see Figure 4 and Figure 5 Inside the housing 1, there is a material frame 5 that moves up and down. Several baffle strips 51 are provided on the bottom inner wall of the material frame 5. The position of the baffle strips 51 is offset from the position of the grinding ring 41. A discharge pipe 52 is provided below the material frame 5.

[0023] In this embodiment, the baffle strip 51 is used to prevent the plant material on the bottom inner wall of the material frame 5 from sliding down too quickly, and to act as a buffer. After grinding, the plant material will slide down and accumulate inside the discharge pipe 52, so that the ground plant material will be discharged from the bottom of the material frame 5.

[0024] Please see Figure 3 , Figure 4 and Figure 5 The material frame 5 is equipped with a rotating grinding disc 4 inside, and the top of the grinding disc 4 is connected to the drive module 2. The lower surface of the grinding disc 4 is a conical surface, and the lower surface of the grinding disc 4 is provided with several closed-loop grinding protrusions 41. The top of the grinding disc 4 is fixedly provided with a connecting seat 42 that is connected to the bottom end of the connecting shaft 24.

[0025] In this embodiment, the rotation of the grinding disc 4 can drive the grinding protrusion 41 on the lower surface to rotate synchronously. When the material frame 5 rises, the baffle strip 51 approaches the grinding protrusion 41, which can grind the plant material on the upper side of the baffle strip 51. As the material frame 5 moves up and down, it can realize multi-level and continuous grinding of plant material, improve the grinding effect of plant material, and facilitate the discharge of plant material from the material frame 5, which is more conducive to cleaning the plant material inside the device.

[0026] Please see Figure 1 , Figure 2 and Figure 7The outer side of the housing 1 is provided with several guide modules 6, and the guide modules 6 are connected to the material frame 5 through the housing 1. The guide module 6 includes an ear seat 61 fixed on the outer wall of the material frame 5, and a guide rod 62 is fixedly installed at the bottom of the ear seat 61. Several guide seats 63 are fixedly provided on the outer wall of the housing 1, and the guide rod 62 is slidably inserted into the inside of the guide seat 63. A compression spring 64 located below the guide seat 63 is sleeved on the outside of the guide rod 62. An adjusting nut 65 is provided at the bottom end of the guide rod 62. By changing the height of the adjusting nut 65 at the bottom end of the guide rod 62, the tightness of the compression spring 64 is adjusted.

[0027] In this embodiment, when the material frame 5 moves up and down inside the housing 1, the ear seat 61 drives the guide rod 62 to move up and down synchronously, so that the guide rod 62 slides inside the guide seat 63. When the guide rod 62 rises, the compression spring 64 shortens and stores force. When the guide rod 62 falls, the compression spring 64 extends, which plays a buffering and stabilizing role in the up and down movement of the material frame 5.

[0028] Please see Figure 1 and Figure 6 A rotating mechanism 7 is provided on one outer wall of the housing 1. The rotating mechanism 7 drives the material frame 5 to move up and down inside the housing 1 through the transmission assembly 8. The rotating mechanism 7 includes a second drive motor 71 fixed on the outer wall of the housing 1, and a rotating arm 72 is connected to the output shaft of the second drive motor 71. A pin 73 is provided above the end of the rotating arm 72. A pull rod 74 is connected to the end of the rotating arm 72 through the pin 73. A timing frame 75 is fixedly connected to one end of the pull rod 74.

[0029] In this embodiment, starting the rotating mechanism 7 can drive the transmission component 8 to move continuously back and forth, thereby realizing the continuous up and down lifting motion of the material frame 5. Starting the drive motor 71 can drive the pull rod 74 to move back and forth using the rotating arm 72, and the synchronous frame 75 moves synchronously with the pull rod 74.

[0030] Please see Figure 2 and Figure 6 The housing 1 contains a transmission assembly 8 located below the material frame 5, and one side of the transmission assembly 8 is connected to the rotating mechanism 7. The transmission assembly 8 includes wheel frames 81 fixed to both sides of the bottom of the material frame 5, and guide wheels 82 are installed below the wheel frames 81. Support seats 83 are fixedly installed on the inner walls of both sides of the housing 1, and push rods 84 are slidably connected above the support seats 83. A wedge block 85 located below the guide wheel 82 is fixedly installed on the top of the push rod 84.

[0031] In this embodiment, the reciprocating linear movement of the push rod 84 can push the guide wheel 82 with the wedge block 85, so that the guide wheel 82 and the wheel frame 81 move up and down synchronously, thereby moving the material frame 5 up and down. Of course, the distance of the material frame 5 moving up and down is not large. The limit of this distance can be determined according to the particle size or the amount of plant material added. Furthermore, the plant material flows down obliquely inside the material frame 5 through the blocking effect of the multi-stage baffle strips 51. Each time the material frame 5 rises, the plant material is ground once, thus achieving a multi-stage grinding effect of the plant material.

[0032] The working principle and usage process of this utility model are as follows: First, the operator adds the plant material from the feed hopper 3, so that the plant material enters the gap between the material frame 5 and the grinding disc 4 inside the shell 1. Start the drive module 2, so that the drive motor 22 drives the grinding disc 4 to rotate through the connecting shaft 24. The grinding of plant raw materials is achieved by rotating the grinding disc 4 inside the material frame 5. When grinding plant materials, the rotating mechanism 7 is activated, which drives the transmission component 8 to operate. The transmission component 8 can drive the material frame 5 to move up and down inside the housing 1. When the material frame 5 is close to the grinding disc 4, the gap decreases, thus achieving the grinding of plant materials. When the material frame 5 descends, the gap between the two increases, which helps the plant materials to flow from a high position to a low position. This achieves efficient grinding of plant materials and also facilitates the discharge of materials inside the material frame 5.

[0033] The rotating mechanism 7 and the transmission assembly 8 move as follows: the drive motor 71 is started, which drives the rotating arm 72 to rotate. The rotating arm 72 and the pin 73 drive the pull rod 74 to move back and forth. The synchronous frame 75 drives the push rod 84 to move back and forth. At the same time, the wedge block 85 on the push rod 84 pushes the guide wheel 82 to move up and down. The wheel frame 81 and the guide wheel 82 rise and fall synchronously, which enables the wheel frame 81 to drive the material frame 5 to move up and down.

[0034] 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.
