DETAILED DESCRIPTION
[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1
[0037] See also Figure 1-9 The utility model is a germination and fermentation box for processing Chinese herbal medicine slices. The germination ring box 8 and the fermentation box frame 4 are driven to rotate by the sealing door 1 2 and the sealing door 2, so as to realize the synchronous and stable operation of germination and fermentation. At the same time, the transparent U plate 801 is slidably arranged in the germination ring box 8, and the fermentation box frame 4 is slidably located in the internal position of the U-shaped plate 5, so as to improve the rapid access to raw materials.
[0038] Specifically, the box body 1; the inside of the box body 1 has a fermentation chamber 102 and a germination chamber 104 respectively arranged on the left and right parts, a sealing door 2 is arranged at the front end of the box body 1 corresponding to the position of the germination chamber 104, a linkage plate 7 is fixed to the rear end surface of the sealing door 2, a germination ring box 8 is arranged just below the linkage plate 7, and a transparent U plate 801 is slidably arranged inside the germination ring box 8;
[0039] Among them, a delivery inlet 702 is provided through the middle position of the upper end surface of the linkage plate 7, a motor 701 is fixed to the upper end surface of the linkage plate 7, a rack 803 passing through the inner position of the delivery inlet 702 is fixed to the upper end surface of the germination ring box 8, and a toothed plate 704 meshingly connected with the rack 803 is fixed to the rotating shaft end of the motor 701. When the sealed door 2 is opened, in order to stably bring out the germination ring box 8, the rack 803 can be driven by the toothed plate 704 to move upward, so that the germination ring box 8 can move upward to a certain height, ensuring that the sealed door 2 can stably bring the germination ring box 8 out of the germination bin 104;
[0040] A sealing door 2 3 is provided at the front end of the box body 1 at a position corresponding to the fermentation bin 102, a U-shaped plate 5 is provided directly behind the sealing door 2 3, a fermentation box frame 4 is slidably provided inside the U-shaped plate 5, a pressing plate 6 having the same shape and size as the inner side surface is provided on the upper end surface of the fermentation box frame 4, and a cylinder 101 having the same upper and lower positions as the pressing plate 6 is fixed on the top of the fermentation bin 102;
[0041] A constant temperature heater 107 connected to the inside of the fermentation bin 102 and the germination bin 104 is fixed to the rear end of the box body 1, a water tank 106 connected to the inside of the germination bin 104 is fixed to the rear end of the box body 1, and a transparent plate 105 is fixed to the left and right sides of the box body 1.
[0042] An exhaust pipe 601 connected to the interior of the fermentation box is fixed on the upper end surface of the pressing plate 6 located on the right side of the cylinder 101. A ball hole 602 is opened on the upper end surface of the exhaust pipe 601. A ball block 605 is arranged inside the ball hole 602. An elastic rope 606 fixedly connected to the upper end surface of the pressing plate 6 is fixed on the surrounding side of the ball block 605. When the ball block 605 is blown up from the position of the ball hole 602, the ball block 605 will pull the elastic rope 606. Therefore, when the ball block 605 is not blown up, the elastic rope 606 will directly drive the ball block 605 into the ball hole 602, thereby sealing the interior of the exhaust pipe 601.
[0043] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, when the raw materials of Chinese herbal medicine slices need to be fermented, the sealing door 23 can be controlled to open, thereby the sealing door will drive the U-shaped plate 5 and the fermentation box frame 4 to rotate out from the internal position of the fermentation bin 102. At this time, the fermentation box frame 4 is pulled out from the internal position of the U-shaped plate 5, and the raw materials are poured into the fermentation box frame 4, and then the fermentation box frame 4 is placed in the internal position of the U-shaped plate 5, and the sealing door 23 is closed, and then the constant temperature heater 107 and the cylinder 101 located behind the fermentation bin 102 are controlled to work, so that the cylinder 101 will push the pressing plate 6 to slide downward inside the fermentation box frame 4 and compress the inside of the fermentation box frame 4. At the same time, the gas inside the fermentation box frame 4 will flow upward from the position of the exhaust pipe 601, so that the ball block 605 floats slightly upward inside the ball mouth 602, and then the gas inside the fermentation box frame 4 is discharged, so as to ensure the sealed environment inside the fermentation box frame 4, so that it can be fermented stably;
[0044] At the same time, when the raw materials need to be germinated, the sealing door 2 can be opened, and the transparent U plate 801 can be pulled out from the inside of the germination ring box 8, and then the raw materials can be poured into the transparent U plate 801 to reset the transparent U plate 801. At this time, the sealing door 2 is rotated and closed, and the motor 701 is controlled to work, so that the motor 701 will drive the rack 803 to move downward through the tooth plate 704, thereby driving the germination ring box 8 and the transparent U plate 801 to the bottom position of the germination bin 104, and then the water tank 106 and the constant temperature heater 107 are controlled to work to ensure that the raw materials are immersed in water and the temperature inside the germination bin 104 is kept constant to ensure stable germination treatment. Specific embodiment 2
[0046] See also Figure 4 , 6 8. Based on the specific embodiment 1, by using a rotating opening method, it is ensured that the sealing door 1 2 and the sealing door 2 3 will not interfere with each other when they are opened separately.
[0047] Specifically, a rotating shaft 103 is fixed to the lower part of the front end surface of the box body 1, and the sealing door 2 is rotatably sleeved on the circumferential side of the rotating shaft 103 through an axial hole 201 that passes through the bottom, and the sealing door 23 is rotatably sleeved on the circumferential side of the rotating shaft 103 through an axial hole 2301 that is opened in the bottom, and the sealing door 23 is fixedly connected to the U-shaped plate 5 by a connecting plate 302 that is set.
[0048] The operation process of this embodiment is as follows: the sealing door 1 2 and the sealing door 2 3 are assembled at the front end surface of the box body 1 through the shaft hole 1 201 and the shaft hole 2 301. Therefore, when the fermentation bin 102 and the germination bin 104 need to be opened, it is only necessary to rotate the sealing door 1 2 and the sealing door 2 3 to open them. At the same time, the rotating opening method is used to ensure that the sealing door 1 2 and the sealing door 2 3 will not interfere with each other when they are opened separately. Specific embodiment three
[0050] See also Figure 2 , 6 7. On the basis of the specific embodiment 1, by setting the spring 2 806, when the tooth plate 704 and the rack 803 fail, it is ensured that the germination ring box 8 can be automatically reset, so that it is easy to take out for maintenance.
[0051] Specifically, the left and right side walls of the germination ring box 8 located above the bottom of the transparent U-plate 801 are provided with a plurality of water holes 802 distributed in an array, and the upper end surface of the linkage plate 7 is provided with positioning holes 703 at the four corners of the upper end surface of the germination ring box 8. Four positioning rods 804 that slide through the internal positions of the positioning holes 703 are fixed to the upper end surface of the germination ring box 8, and circular plates 805 are fixed to the upper end surfaces of the positioning rods 804 that pass through the positioning holes 703, and springs 806 that are mounted on the sides of the positioning rods 804 and connected to the upper end surface of the linkage plate 7 are fixed to the lower end surfaces of the circular plates 805.
[0052] The operation process of this embodiment is: when the tooth plate 704 is controlled to drive the rack 803 to move downward, the rack 803 will drive the germination ring box 8 to move downward, so that the positioning rod 804 will slide along the positioning hole 703, and thereby control the circular plate 805 to compress the spring 2 806. Therefore, when the tooth plate 704 cannot ensure the stability of the rack 803, the spring 2 806 will directly push the circular plate 805 to move upward, so that the germination ring box 8 is reset to the initial position, ensuring that the germination ring box 8 can be stably taken out by the sealing door 2. Specific embodiment 4
[0054] See also Figure 3 , 8 9. Based on the specific embodiment 1, the L-shaped plate 603 is reset and pushed by the spring 1 502 to facilitate the pulling of the fermentation box frame 4.
[0055] Specifically, two L-shaped plates 603 symmetrically arranged on the front and rear parts of the upper end surface of the pressure plate 6 are fixed, and abutment blocks 501 are fixed at the positions of the front and rear side surfaces of the U-shaped plate 5 corresponding to the positions of the L-shaped plates 603. A limiting hole 604 is penetrated through the position of the upper end surface of the L-shaped plate 603 corresponding to the position of the abutment block 501. A limiting rod 504 that slides through the internal position of the limiting hole 604 is fixed on the upper end surface of the abutment block 501. A stopper 503 is fixed on the upper end surface of the limiting rod 504. A spring 502 connected to the lower surface of the L-shaped plate 603 is fixed on the upper end surface of the abutment block 501.
[0056] The operation process of this embodiment is as follows: when the cylinder 101 pushes the pressing plate 6 to move downward, it will drive the L-shaped plate 603 to slide along the limiting rod 504, and thereby compress the spring 1 502, and then the pressing plate 6 will compress the inside of the fermentation box frame 4. At the same time, after the cylinder 101 is reset, the spring 1 502 can push the L-shaped plate 603 to reset, so that the L-shaped plate 603 is moved out of the internal position of the fermentation box frame 4. At this time, the fermentation box frame 4 can be conveniently pulled out from the internal position of the U-shaped plate 5.
