DETAILED DESCRIPTION

[0023] like Figures 1 to 5 As shown, the utility model provides a tea-tea-killing device for processing tea leaves, comprising an outer bucket 1 and an inner bucket 3 coaxially connected to the outer bucket 1 through two connecting strips 2; a rotating column 4 coaxially rotatably connected to the outer bucket 1 and in contact with the bottom side of the inner bucket 3; a plurality of supporting legs 5 are connected to the bottom end of the outer bucket 1; a tea-killing motor 6 is installed at the bottom end of the outer bucket 1; the power end of the tea-killing motor 6 rotates and penetrates the bottom wall of the outer bucket 1 and is coaxially connected to the rotating column 4; a tea-killing space is formed between the outer bucket 1, the inner bucket 3 and the rotating column 4; the circumference of the rotating column 4 is Several withering rods 7 are evenly arranged in the withering space; each withering rod 7 has a fixed cavity, and the circumferential side of the withering rod 7 is axially provided with a through groove 8 connected to the fixed cavity; a screw is rotatably connected between the opposite side walls of each fixed cavity; a slide plate 9 slidably arranged in the fixed cavity is threadedly sleeved on each screw; a protrusion slidably arranged in the through groove 8 is provided on one side of each slide plate 9; a scraper ring 10 slidably sleeved on the withering rod 7 is connected to each protrusion; heating elements are provided on the opposite side walls of the outer bucket 1 and the inner bucket 3.

[0024] The principle and beneficial effects of the above technical solution:

[0025] Pour the tea leaves into the withering space, transfer heat through the heating element, and drive the rotating column 4 to rotate through the withering motor 6, so that the withering rod 7 can stir the tea leaves. In the middle, sprinkle a proper amount of water into the withering space as needed to avoid the tea leaves turning black due to too high temperature. When the withering is completed, take out the tea leaves in the withering space. At this time, some of the tea leaves may adhere to the outer wall of the withering rod 7. By controlling the rotation of the screw, the slide plate 9 can be driven to slide in the fixed cavity, thereby driving the scraper ring 10 to move along the axial direction of the withering rod 7 through the protrusion, and then the tea leaves adhered to the outer wall of the withering rod 7 can be scraped off so that they can fall into the withering space. Then tilt the device to pour out this part of the tea leaves.

[0026] In the present application, the rotation of the screw can make the slide plate 9 slide, thereby driving the scraper ring 10 to move along the outer wall of the withering rod 7 through the protrusion, and then the tea leaves that may adhere to the outer wall of the withering rod 7 during the withering process can be scraped off, so that this part of the tea leaves can also be taken out, avoiding the waste caused by adhesion to the withering rod 7.

[0027] In this embodiment, Figure 4 As shown, each scraper ring 10 has an annular cavity; an annular groove with a T-shaped cross-section is opened on the inner wall of each annular cavity at one end away from the killing rod 7 (not shown in the figure); a frame 11 is slidably connected in each annular groove; the frame 11 is slidably set in the annular groove through a slider 12; each frame 11 has a movable groove arranged along the radial direction of the killing rod 7; a movable rod is slidably set in each movable groove through a spring; each movable rod is connected to a collision ball block 13 exposed outside the movable groove at one end away from the spring; in each annular cavity, a plurality of fixed ball blocks 14 are evenly arranged on the inner wall of one of the rings; when the frame 11 slides in the annular groove, the collision ball block 13 can collide with the fixed ball block 14.

[0028] The principle and beneficial effects of the above technical solution:

[0029] By controlling the slider 12 to slide in the annular groove, the frame 11 can make a circular motion, so that the collision ball block 13 can collide with each fixed ball block 14 in turn, thereby generating vibration, so that the tea leaves adhering to the scraper ring 10 fall off during the movement of the scraper ring 10 along the killing rod 7, thereby avoiding the waste of tea leaves. The setting of the spring allows the collision ball block 13 and the moving rod to move into the moving groove when the collision ball block 13 collides with the fixed ball block 14. After the collision is completed, the collision ball block 13 can extend out of the moving groove again under the action of the spring to prepare for the next vibration.

[0030] In this embodiment, Figure 4 As shown, in each annular cavity, a gear ring 15 is sleeved on the inner wall of another ring; a rotating motor is connected to each frame 11; and a gear 16 meshing with the gear ring 15 is connected to the power end of each rotating motor.

[0031] The principle and beneficial effects of the above technical solution:

[0032] The rotating motor drives the gear 16 to rotate, so that under the action of the gear ring 15 , the rotating motor drives the frame 11 to move in a circle, so that the collision ball block 13 can collide with each fixed ball block 14 .

[0033] In this embodiment, Figure 3 , 4 As shown, a number of fixing seats are evenly arranged on the circumference of each rotating column 4, and threaded holes are opened on the fixing seats; one end of each withering rod 7 is threadedly connected to the corresponding threaded hole through a connecting rod 17; a receiving groove is opened in each connecting rod 17; a tea scraping motor 18 facing the withering rod 7 is installed in each receiving groove; the power end of each tea scraping motor 18 rotates to extend into the fixed cavity and is connected to one end of the screw; the other end of each screw is rotatably connected to the corresponding side wall of the fixed cavity.

[0034] The principle and beneficial effects of the above technical solution:

[0035] By controlling the rotation direction of the power end of the tea scraping motor 18, the rotation direction of the screw can be controlled, so that the slide plate 9 can reciprocate in the fixed cavity, thereby driving the scraping ring 10 to reciprocate on the withering rod 7 to scrape off the tea leaves adhering to the withering rod 7.

[0036] The cooperation between the connecting rod 17 and the fixing seat facilitates the disassembly of the killing rod 7 for maintenance.

[0037] In this embodiment, Figure 5 As shown, the circumferential side of the rotating column 4 is radially connected with a scraper bar (not shown in the figure) that is in sliding contact with the inner bottom wall of the outer bucket 1, and the scraper bar is located in the killing space; the outer bottom wall of the outer bucket 1 is opened with a discharge hole facing the killing space; the discharge hole is threadedly connected with a discharge column 19.

[0038] The principle and beneficial effects of the above technical solution:

[0039] When the tea leaves are withered, the discharge column 19 is unscrewed and the tea leaves can be discharged through the discharge hole. The rotating column 4 can drive the scraper bar to slide in contact with the inner bottom wall of the outer bucket 1, pushing the remaining tea leaves into the discharge hole to improve the thoroughness of the discharge.

[0040] In this embodiment, Figure 1 As shown, the heating element includes two electric heating ring plates 20 respectively connected to the outer wall of the outer bucket 1 and the inner wall of the inner bucket 3.

[0041] The principle and beneficial effects of the above technical solution:

[0042] The electric heating ring plate 20 is heated by an external power source, and the heat is transferred to the withering space through the inner bucket 3 and the outer bucket 1 to wither the tea leaves.

[0043] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
