DETAILED DESCRIPTION

[0023] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0024] Embodiment: A raw material drying equipment for extracting plant essential oils, such as Figures 1-6As shown, it includes a drying box 1, a box door 11, a drying component 12 and a placement frame 13. The box door 11 is rotatably connected to the front end of the drying box 1. A drying component 12 for drying plant materials is installed on the drying box 1. The drying component 12 is used for heating and ventilating the drying box 1, and monitoring the temperature and humidity in the drying box 1 to ensure that the drying process in the drying box 1 is carried out normally. A placement frame 13 is provided in the drying box 1, and also includes a guide seat a2, a frame 21, an elastic member a22, a flipping component, a bending push rod 4, a push plate 41 and a torsion spring 42. The guide seat a2 is fixed to the front and rear ends on the left and right sides of the drying box 1. There are two cylindrical sliding connections on the guide seat a2. Frame 21, the placement frame 13 is slidably connected in the frame 21, and elastic parts a22 are sleeved on the two cylinders of the guide seat a2. One end of the elastic part a22 is fixed to the guide seat a2, and the other end is fixed to the frame 21. A turning component for turning the plant raw materials is provided in the drying box 1, and a push plate 41 is rotatably connected on the left and right sides in the placement frame 13. A torsion spring 42 is sleeved on both ends of the push plate 41. One end of the torsion spring 42 is fixed to the push plate 41, and the other end is fixed to the placement frame 13. One end of the bending push rod 4 is fixed to the bottom of the guide seat a2, and the other end can pass through the placement frame 13 and contact with the push plate 41. In a stationary state, the bending push rod 4 has no contact with the placement frame 13.

[0025] like Figure 1 、 Figure 3 and Figure 4 As shown, the flipping assembly includes a motor 3, a chain 31, a sprocket 32, a fixed seat 33, a transmission rod 34 and a cam 35. The motor 3 is installed outside the drying box 1. The rotation speed of the motor 3 can meet the acceleration of the placement frame 13 at the moment of movement, which is greater than the acceleration of gravity. The transmission rod 34 is connected to the output shaft of the motor 3, and the transmission rod 34 is rotatably connected to the bottom of the drying box 1. Sprockets 32 are fixed at both ends of the transmission rod 34. Fixed seats 33 are fixed on the left and right sides of the drying box 1. The sprocket 32 is rotatably connected to the fixed seat 33. A chain 31 is sleeved between the sprockets 32 on the same side. The chain 31 is meshed with the sprocket 32. A cam 35 is fixed to the central axis of the sprocket 32 rotatably connected to the fixed seat 33. The cam 35 is slidably connected to the top of the frame 21.

[0026] The staff puts the processed plant raw materials into the placement frame 13, and then puts the placement frame 13 into the frame 21. After it is full, the box door 11 is closed, and the drying component 12 and the motor 3 are turned on. The drying component 12 provides heat to the drying box 1 to dry the plant raw materials. The motor 3 drives the transmission rod 34 to rotate, thereby driving all the sprockets 32 to rotate through the chain 31, so that the cam 35 connected to the sprocket 32 rotates, and the cam 35 squeezes the frame 21. The contact between the cam 35 and the frame 21 moves from the inner circle to the outer circle, pressing the frame 21 downward, compressing the elastic part a22, and at the same time bending the top rod 4 to squeeze the push plate 41, twisting the torsion spring 42, and the push plates 41 on both sides push the plant raw materials to the middle. When the contact between the cam 35 and the frame 21 moves from the outer circle to the inner circle, the elastic part a22 rebounds to reset the frame 21 upward, and the bending top rod 4 is disengaged from the push plate 41, and the torsion spring 4 2 Rebound causes the push plate 41 to reset. During the downward movement of the frame 21, the acceleration of the frame 21 is greater than the acceleration of gravity, so the plant material is suspended for a moment, especially after gradual drying, the plant material is lighter, so that the plant material laid on the bottom of the placement frame 13 can be suspended to the height of the upper end of the push plate 41 when the push plate 41 rotates, so that the plant material can be thrown to the middle, sifting the plant material while changing the position of the plant material to achieve a turning effect. Different plant materials are set with corresponding drying time, so when setting the time, the staff closes the drying component 12, opens the box door 11, and checks the drying status of the plant material. If the drying is completed, the plant material is taken out. If the drying is not completed, it is briefly dried according to the situation, thereby reducing the number of times the box door 11 is opened in the middle, which can effectively shorten the drying time and save energy.

[0027] like Figure 3 and Figure 7 As shown, it also includes a limit plate 5, a guide sleeve 51, a pull rod 52 and an elastic member b53. The limit plate 5 is fixed to the left and right sides of the front end of the frame 21, the guide sleeve 51 is fixed to the front end of the placement frame 13, and the two pull rods 52 are slidably connected to the guide sleeve 51. The pull rods 52 are in opposite directions. The separated ends of the two pull rods 52 are slidably connected in the limit plate 5. A pull ring is provided at the end where the two pull rods 52 are close to each other. The separated ends of the two pull rods 52 are trapezoidal blocks with the long side facing outward and the short side facing inward. An elastic member b53 is sleeved on the pull rod 52. One end of the elastic member b53 is fixed to the guide sleeve 51, and the other end is fixed to the pull rod 52.

[0028] like Figure 1 and Figure 7 As shown, a handle 8 is also included. The handle 8 is fixedly connected to the middle of the front end of the placement frame 13 and is located in the middle of the two pull rods 52 near one end. The handle 8 is provided on the box door 11.

[0029] When placing the placement frame 13, the placement frame 13 slides into the frame 21, and the pull rod 52 contacts the limiting piece 5 and compresses the elastic part b53. Then, after passing one side of the limiting piece 5, the elastic part b53 rebounds, causing the pull rod 52 to be inserted into the limiting piece 5, thereby limiting the placement frame 13. When taking out the placement frame 13, it is more convenient to open the box door 11 through the handle 8, and the staff can pull the two pull rods 52 from the middle with one hand. After the two pull rods 52 are close to each other, the staff can also grab the handle 8 on the placement frame 13, pull the pull rod 52 to contact and fix the placement frame 13 while pulling out the placement frame 13. Only one hand is needed to complete the unlocking and pulling out actions. After placing it in, the placement frame 13 moves up and down more stably, and the removal process is also very convenient.

[0030] like Figure 5 and Figure 8 As shown, it also includes a guide seat b6, a sliding frame 61 and an elastic member c62. The guide seat b6 is fixedly connected to the frame 21, and the sliding frame 61 is slidably connected to the guide seat b6. The elastic member c62 is sleeved on the guide seat b6, and one end of the elastic member c62 is fixedly connected to the guide seat b6, and the other end is fixedly connected to the sliding frame 61.

[0031] like Figure 5 and Figure 8 As shown, it also includes a guide frame 7, a trapezoidal push block 71 and a triangular block 72. The guide frame 7 is fixedly connected to the frame 21, the trapezoidal push block 71 is slidably connected to the guide frame 7, and the triangular block 72 is fixedly connected to the sliding frame 61. The triangular block 72 is slidably connected to the trapezoidal push block 71.

[0032] When the door 11 is closed, the door 11 squeezes the trapezoidal push block 71, and the trapezoidal push block 71 slides backward on the guide frame 7, while squeezing the triangular block 72 downward, thereby pressing down the sliding frame 61 and compressing the elastic member c62, so that the sliding frame 61 covers the placement frame 13, so that when the placement frame 13 is shaken up and down, it can play a blocking role on the plant material, especially when the placement frame 13 stops moving upward, the plant material will continue to move upward under the action of inertia. When the placement frame 13 moves downward again, the plant material may still be moving upward or suspended. In this way, the sliding frame 61 can ensure the use effect of the push plate 41. When the cabinet door is opened, the elastic member c62 rebounds, causing the sliding frame 61 to leave the placement frame 13, so that when the placement frame 13 is taken out, there is no need to overcome the friction between the placement frame 13 and the sliding frame 61.

[0033] like Figure 1 As shown, a lamp 9 is also included. The lamp 9 is arranged on the top of the drying box 1 and has the characteristic of high temperature resistance.

[0034] like Figure 1 and Figure 2As shown, a transparent plate 10 is also included, and the transparent plate 10 is arranged on the box door 11.

[0035] Turn on the light 9 and observe the drying situation in the drying box 1 through the transparent plate 10, so that when the time is set, it is possible to determine whether the plant material is dried without opening the door 11. The door 11 only needs to be opened once from the time the plant material is put in to the time the drying is completed.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
