DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] See also Figure 1-8 One embodiment of the present invention is: a tea fermentation device with uniform turning, comprising a fermentation box 1, and further comprising:

[0055] The heating cylinder 2 is fixedly connected to the top of the fermentation box 1, and the connection points are interconnected;

[0056] The waste trough 3 is fixedly connected to the bottom of the fermentation box 1, and the connections are interconnected, so as to collect the impurities on the tea net 5 into the waste trough 3, and take them out through a door arranged on the front side of the waste trough 3.

[0057] A plurality of legs 4 are fixedly connected to the bottom of the fermentation box 1;

[0058] The tea net 5 is arranged inside the fermentation box 1 and is used to place tea leaves;

[0059] A toggle mechanism 6 is arranged inside the fermentation box 1 and is used to toggle the tea leaves;

[0060] The smoothing mechanism 7 is arranged inside the fermentation box 1 and located on the tea net 5, and is used to smooth the tea leaves;

[0061] Among them, Tea Network 5 includes:

[0062] The inner wall of the fermentation box 1 is provided with arc grooves on both the front and rear sides, and a plurality of movable rods 51 are slidably connected in the arc grooves, and the front and rear sides of the movable rods 51 are fixedly connected with column blocks and slide in the arc grooves;

[0063] A plurality of elastic ropes 52 are fixedly connected to the outer wall of each movable rod 51 in sequence, and the gap between the elastic rope 52 and the movable rod 51 is smaller than the gap between the tea leaves;

[0064] A pull rope 53 is movably connected inside the columnar block, and one end of the pull rope 53 movably passes through the fermentation box 1 and extends outward, so as to pull the pull rope 53, shrink the multiple columnar blocks to move closer to each other, and straighten the tea net 5 from a bent state.

[0065] The right side of the outer wall of the fermentation box 1 is fixedly connected with a housing 55, and the inner wall of the housing 55 is rotatably connected with a winding drum 54, and the outer wall of the winding drum 54 is connected with a pull rope 53 for winding the pull rope 53;

[0066] A motor 56 is installed on the back of the chassis 55, and the output end of the motor 56 is fixedly connected to the driving shaft of the winding drum 54 for driving the winding drum 54 to rotate.

[0067] Working principle: When tea leaves are fermented, tea leaves are first added through the feeding door on the front of the fermentation box 1, and the tea leaves will fall evenly onto the tea net 5. When the reel 54 does not apply force to the pull rope 53, the multiple movable rods 51 on the tea net 5 will disperse from each other in the arc groove under the action of the tea leaves and their own gravity, and pull the elastic rope 52 to open. At this time, the tea leaves will fall evenly into the tea net 5, waiting for the toggle mechanism 6 to perform the toggle turning operation.

[0068] When the placement form of the tea leaves needs to be changed to optimize the fermentation effect, the motor 1 56 is started, and the motor 1 56 drives the winding drum 54 to rotate and wind up the drawstring 53. As the drawstring 53 is wound up, the movable rod 51 movably connected to the drawstring 53 is pulled and contracted, so that the tea net 5 is gradually straightened from the bent state. This process not only changes the placement form of the tea leaves, but also increases the contact area between the tea leaves and the air by changing the form, thereby optimizing the fermentation effect.

[0069] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the toggle mechanism 6 includes:

[0070] A rotating shaft 61 is rotatably connected to the inner wall of the fermentation box 1;

[0071] Two sliding seats 64 are slidably connected to the outer wall of the rotating shaft 61 and rotate along with the rotating shaft 61;

[0072] The bottom of the shear rod 62 is hinged on two slide seats 64 respectively, and the top of the shear rod 62 is connected to a lever 63 through the two slide seats 64 for moving the tea leaves.

[0073] Two tea leaves nets 5 are provided, and the other set is symmetrically arranged inside the fermentation box 1 , and the inner wall of the upper tea leaves net 5 contacts the outer wall of the lever 63 to squeeze the lever 63 and contract the shear rod 62 .

[0074] A plurality of heating rods 9 are installed inside the heating cylinder 2, and an air inlet pipe 8 is connected to one side of the heating cylinder 2;

[0075] The outer wall of the movable rod 51 of the upper tea net 5 is fixedly connected with two return springs 65, and the top of the return spring 65 is connected to the top of the inner wall of the heating cylinder 2, so as to return the tea net 5 upward;

[0076] The second motor 66 is installed on the back of the fermentation box 1, and the output end of the second motor 66 is connected to the rotating shaft 61 to drive the rotating shaft 61 to rotate.

[0077] Working principle: After the shape of the tea net 5 is adjusted, the toggle mechanism 6 starts to work. The motor 2 66 is started, and the motor 2 66 drives the rotating shaft 61 to rotate. During the rotation of the rotating shaft 61, the lever 63 opens under the combined action of gravity and centrifugal force. When the lever 63 rotates to the top of the tea net 5, it will contact the tea leaves on the tea net 5, thereby realizing the toggle and flip operation of the tea leaves.

[0078] In particular, when the tea net 5 is straightened, the rotation shaft 61 stops rotating, and the upper part of the lever 63 faces the upper tea net 5. At this time, the upper tea net 5 is gradually straightened and contacts the lever 63, pushing the shear rod 62 to contract. This process not only realizes the turning over of the tea leaves, but also further optimizes the turning over effect of the tea leaves through the contraction and expansion of the shear rod 62, ensuring that the tea leaves can be evenly heated and exposed to air during the fermentation process.

[0079] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the smoothing mechanism 7 includes:

[0080] A smoothing component 71 is arranged on the inner wall of the fermentation box 1 and is used to smooth the tea leaves;

[0081] Two slide bars 72 are fixedly connected to the inner wall of the arc-shaped groove of the fermentation box 1, and the smoothing component 71 slides on the outer wall of the slide bars 72;

[0082] Two connecting rods 74 are fixedly connected to both sides of the outer wall of the rotating shaft 61;

[0083] The limiting rod 75 is fixedly connected to the bottom of the connecting rod 74, and a plurality of limiting protrusions 76 are fixedly connected to the bottom of the limiting rod 75;

[0084] A spherical block 78 is disposed on the smoothing component 71 , and the spherical block 78 is in contact with the limiting protrusion 76 .

[0085] A spherical groove 77 is provided above the inner wall of the arc-shaped groove of the fermentation box 1, and the spherical groove 77 fits with the spherical block 78 to limit the movement of the smoothing component 71;

[0086] Wherein, the smoothing component 71 comprises:

[0087] Two sliders 713 are slidably connected to the outer wall of the slide rod 72, and one side of the sliders 713 is provided with a mounting groove, and a fixing rod 715 is fixedly connected in the mounting groove;

[0088] The smoothing block 711 moves in the installation groove and is sleeved on the outer wall of the fixing rod 715, and the spherical block 78 is fixedly connected to the top of the smoothing block 711;

[0089] Two springs 716 are sleeved on the outer wall of the fixing rod 715 and are respectively located on both sides of the smoothing block 711 for resetting the smoothing block 711 .

[0090] The bottom of the smoothing block 711 is fixedly connected with bristles 712 for brushing the tea leaves;

[0091] A sliding hole 73 is provided on the front side of the fermentation box 1 , and a shifting block 714 is slidably connected to the inner wall of the sliding hole 73 , and the shifting block 714 is connected to the sliding block 713 for pushing the sliding block 713 to move.

[0092] Working principle: After the tea leaves are turned over, the smoothing mechanism 7 starts to work. Pushing the shifting block 714 will drive the slider 713 to slide on the outer wall of the slide rod 72, thereby pushing the smoothing block 711 to move. The brush 712 at the bottom of the smoothing block 711 will brush the tea leaves on the tea net 5 to smooth the tea leaves.

[0093] During the smoothing process, the spherical block 78 above the smoothing block 711 will contact the limiting protrusion 76. The limiting protrusion 76 will contact the spherical block 78 and cooperate with the spring 716 to produce an up-down misalignment effect. This process not only allows the smoothing block 711 and the bristles 712 to rise and fall, but also improves the smoothing effect, ensuring that the tea leaves can be evenly exposed to the air during the fermentation process, further optimizing the fermentation effect.

[0094] At the same time, when the tea net 5 returns to the bent state, the return spring 65 pulls the tea net 5 to return upward. This process not only provides enough space for the rotation of the lever 63, but also improves the adaptability and flexibility of the device, ensuring that the best fermentation effect can be achieved at different fermentation stages.

[0095] The present invention provides a tea fermentation device for uniform turning over. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
