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.

[0020] See also Figure 1-8 One embodiment of the present invention is: a fermentation barrel suitable for tea processing, comprising a barrel body 1, and also comprising: A plurality of legs 2 are equally divided and fixedly connected to the bottom of the barrel body 1 to support the barrel body 1 off the ground; Two loading covers 3 are symmetrically mounted on the front and rear sides of the top of the barrel body 1 and are used to load tea material into the barrel body 1; Two discharge covers 4 are symmetrically mounted on the front of the barrel body 1 and are used to discharge tea leaves after fermentation in the barrel body 1; A stirring mechanism 5 is arranged inside the barrel body 1 and is used to stir and turn the tea leaves; The material lifting mechanism 6 is arranged on the inner wall of the barrel body 1 and is used to lift the tea leaves upward; The separation plate 7 is fixedly connected to the inner wall of the barrel body 1 and is used to separate impurities inside the tea leaves; The ventilation mechanism 8 is arranged inside the barrel body 1 and is used to ventilate the inside of the barrel body 1; Wherein, the stirring mechanism 5 comprises: The rotating drum 51 has two ends rotatably connected to the separation plate 7 and the top of the inner wall of the barrel body 1 through bearings; A plurality of stirring rods 52 are connected to the outer wall of the rotating drum 51 in groups of three at equal intervals in the longitudinal direction and in a circle equally divided by the circumference, and are used to stir the tea leaves; A plurality of connecting plates 53 connected to the three groups of stirring rods 52; The motor 54 is installed on the top of the barrel 1, and its output end is connected to the top of the drum 51 through a coupling; The extension mechanism 55 is provided on each stirring rod 52 and is used for extending the stirring of tea leaves.

[0021] The extension mechanism 55 comprises: The extension rod 551 is movably connected to the inner wall of the stirring rod 52; Two spring sleeves 552 are symmetrically connected to the outer wall of the extension rod 551 and slide on the inner wall of the stirring rod 52; The spring 553 is connected to the inner side of the spring sleeve 552 and the inner wall of the stirring rod 52, and is used to push the spring sleeve 552 and the extension rod 551 to move outward.

[0022] The extension mechanism 55 further comprises: The tilting rods 554 are hinged to the upper and lower sides of the outer wall of the stirring rod 52 in a group of two, and a coil spring is provided at the hinge to stir the tea leaves; Two push blocks 555 are movably connected in the stirring rod 52, and the outer sides thereof abut against one side of the tilting rod 554 to push the tilting rod 554 to rotate; The two wedge-shaped sliders 556 are respectively connected to the outer wall of the extension rod 551 , and one side of the wedge-shaped sliders 556 is in contact with the side of the push block 555 away from the tilting rod 554 , so as to push the push block 555 to move.

[0023] Working principle: when the tea leaves are fermented, the tea leaves to be fermented are put in from the loading cover 3, and the motor 54 is started to drive the drum 51 to rotate, which will drive the multiple stirring rods 52 to rotate, so that the tea leaves can be stirred to promote their separation and prevent the tea leaves from sticking together and affecting the fermentation effect. At the same time, during the stirring, the extension rod 551 is pushed outward by the spring 553, and after contacting the movable block 63, the spring 553 is compressed, so that the extension rod 551 is retracted into the inner wall of the stirring rod 52, thereby achieving the length of the stirring rod 52 and the stirring effect at different places. At the same time, during its contraction process, the wedge-shaped slider 556 is pushed to move so as to no longer exert force on the push block 555, so that the two tilting rods 554 are pulled closer to each other under the action of the coil spring; At the same time, when the extension rod 551 is out of contact with the movable block 63, the spring 553 pushes it to move outward, thereby expanding the stirring range. At the same time, during the outward movement of the extension rod 551, the wedge-shaped slider 556 is driven to move outward, and the push block 555 is pushed outward to push the two tilting rods 554 to open outward, thereby expanding the stirring range and improving the stirring effect.

[0024] See also Figure 1-8 On the basis of the above embodiment, in another embodiment of the present invention, the material lifting mechanism 6 comprises: The spiral lifting plate 61 is installed on the inner wall of the barrel body 1 and rotates relative to the inner wall of the barrel body 1; Two arc-shaped plates 62 are connected to the inner side of the spiral lifting plate 61; The interior of the arc-shaped plate 62 is hollow, and grooves are arranged at intervals that are the same as the intervals between the longitudinal stirring rods 52; A plurality of movable blocks 63 are movably connected to the inner wall of the arc plate 62 and connected through the connecting block 64. After contacting with the extension rod 551, the arc plate 62 is pushed to drive the spiral lifting plate 61 to rotate; The top push block 65 is fixedly connected to the top of the barrel body 1 and contacts the top of the connecting block 64 to push the movable block 63 to move downward.

[0025] The top push block 65 is arranged with arc shapes on both sides, and after contacting the connecting block 64 , pushes the connecting block 64 and the movable block 63 downward, so that the extension rod 551 is out of contact with the movable block 63 .

[0026] The material lifting mechanism 6 also includes: A plurality of elastic rods 66 are mounted on the inner wall of the barrel body 1; The spiral lifting plate 61 is provided with spaced through holes for the elastic rods 66 to pass through when the spiral lifting plate 61 rotates, thereby moving and crushing the tea leaves.

[0027] Working principle: When the extension rod 551 contacts the connection block 64, it will simultaneously push the spiral lifting plate 61 to rotate inside the barrel body 1, thereby moving the tea leaves on the separation plate 7 and moving them upward along the outer wall thereof. During its rotation, it will continuously contact the multiple elastic rods 66, thereby generating contact and crushing the tea leaves. At the same time, the tea leaves on the spiral lifting plate 61 can be moved and dropped into the barrel body 1, and stirred in cooperation with the stirring mechanism 5. Furthermore, when the spiral lifting plate 61 is pushed to rotate, the movable block 63 follows and drives the connecting block 664 to rotate. After contacting the top push block 65, it pushes the connecting block 664 downward. In the process of moving downward, multiple movable blocks 63 are simultaneously pushed downward, so that the movable block 63 is out of contact with the extension rod 551, thereby prompting the extension rod 551 to move outward and no longer push the movable block 63, so as to temporarily release the lifting of the spiral lifting plate 61.

[0028] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the ventilation mechanism 8 includes: The rotating shaft is fixedly connected to the bottom of the inner wall of the barrel body 1 and movably penetrates the inner wall of the rotating drum 51; A plurality of spiral blocks 83, equally divided and fixedly connected to the outer wall of the rotating shaft, for rotating the compressed air; An air inlet is provided at the top of the drum 51 for taking in air; A plurality of ventilation holes 84 are provided at the connection between the rotating drum 51 and the stirring rod 52; A plurality of gas outlet holes 85 are provided on the outer wall of the stirring rod 52 for discharging gas to the outside.

[0029] The conical heating plate 81 is fixedly connected to the top of the separation plate 7 and rotates relative to the rotating drum 51; The arc-shaped scraper strip 82 is connected to the outer wall of the rotating drum 51 and is attached to the outer wall of the conical heating plate 81 to move the tea leaves outward.

[0030] Working principle: When the drum 51 rotates continuously, it will rotate relative to the multiple spiral blocks 83 arranged inside it, and the air is compressed through the internal rotation, and then the air is discharged along the ventilation holes 84 and the air outlet holes 85, so that the external air can be compressed into the barrel body 1 for air exchange, thereby increasing the internal oxygen to promote aerobic fermentation. At the same time, the air can be exhausted through the air outlet holes 85 and blown onto the falling tea leaves, thereby achieving the turning effect of the tea leaves and further improving the fermentation effect. At the same time, the tea leaves are heated by the conical heating plate 81, and the top is scraped by the arc-shaped scraper 82 to prevent the tea leaves from adhering to the conical heating plate 81. At the same time, the temperature inside the barrel body 1 can be controlled to improve the fermentation effect.
