Description

Technical Field

[0001] This utility model relates to the field of tea production technology, specifically to a tea-spreading and dispersing device. Background Technology

[0002] Tea originated in China. Its leaves are leathery, oblong or elliptical, and can be brewed directly with boiling water. Based on variety, processing method, and product appearance, it is divided into six major categories. Based on seasonal harvesting, it can be divided into spring tea, summer tea, autumn tea, and winter tea. Various raw or refined tea leaves are further processed to form processed teas, including scented tea, compressed tea, extracted tea, medicinal and health tea, tea-based foods, and tea-containing beverages. Modern tea production is mainly mechanized, where each batch of fresh tea leaves undergoes a series of processing steps to obtain a ready-to-brew finished product. Modern people have an increasing demand for tea and higher requirements for tea quality; therefore, tea processing technology is constantly being improved to produce teas that better suit people's tastes. The tea processing process mainly includes sun-drying, fixation, rolling, drying, and sorting. Currently, tea production equipment is becoming increasingly automated, using conveyor belts, elevators, and other devices to connect different equipment, thus completing the processing in one go through a complete production line.

[0003] Currently, existing tea production processes require separate screening using various screening equipment such as circular sieves and air separators. That is, the tea leaves screened from the front-end equipment are transported by a lifting conveyor to the inlet of the next piece of equipment for further screening.

[0004] In the above scheme, since the lifting conveyor is generally set with the left side lower and the right side higher, it cannot effectively spread the tea leaves out evenly, causing the tea leaves to pile up and thus affecting the tea leaf screening effect. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tea-spreading and dispersing device. By incorporating a dispersing roller, the tea can be dispersed, solving the problem of tea accumulation when transported by a lifting conveyor, thus ensuring that the tea screening effect is not affected.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A tea-spreading and dispersing device includes a support frame and a lifting conveyor. Baffles are installed on the four sides of the lifting conveyor, and dispersing rollers are installed inside the baffles. A limiting groove is formed on each side of the baffle, and two limiting blocks are fixed on each side of the baffle. A slider is inserted between the two limiting blocks. The two ends of the dispersing roller are rotatably connected to the two sliders respectively. A rotating mechanism is provided at the end of the dispersing roller. The rotating mechanism includes a connecting component and a rotating component. A lifting component is provided at the upper end of the baffle.

[0008] When tea needs to be transported by a lifting conveyor, the lifting component is activated to drive the dispersing roller to rise and fall. The distance between the dispersing roller and the lifting conveyor belt is adjusted to adjust the thickness of the tea leaves after passing through the dispersing roller. The rotating component is activated, and the dispersing roller is rotated through the connecting component to disperse the tea leaves after passing through the dispersing roller, thereby preventing the tea leaves from piling up.

[0009] By incorporating a dispersing roller, the tea leaves can be dispersed, solving the problem of tea leaf accumulation that easily occurs when transporting tea leaves via a lifting conveyor, thus ensuring that the tea leaf selection effect is not affected.

[0010] The utility model is further configured such that: the connecting assembly includes a first bevel gear fixed on the protruding end of the dispersing roller passing through the slider; a support plate is fixed on the side wall of the slider; a first rotating shaft is rotatably connected to the upper end of the support plate; a second bevel gear meshing with the first bevel gear is fixed to the top end of the first rotating shaft; a first gear is fixed to the protruding end of the first rotating shaft passing through the support plate; a connecting plate is fixed to the side wall of the baffle; a second rotating shaft is rotatably connected to the upper end of the connecting plate; a second gear meshing with the first gear is fixed to the side wall of the second rotating shaft; a third bevel gear is fixed to the top end of the second rotating shaft; a third rotating shaft is fixed to the side wall of the connecting plate; and a fourth bevel gear meshing with the third bevel gear is fixed to the end of the third rotating shaft.

[0011] Through the above technical solution, by providing a connecting component, the dispersing roller can be driven to rotate after being raised and lowered. When it is necessary to drive the dispersing roller to rotate, the rotating component drives the fourth bevel gear to rotate, the fourth bevel gear to rotate, the third bevel gear to rotate, the third bevel gear to rotate, the second gear to rotate, the second gear to rotate, and simultaneously drive the second bevel gear to rotate, and the second bevel gear to rotate, thereby driving the dispersing roller to rotate.

[0012] The utility model is further configured such that: the rotating component includes a first pulley fixed on the protruding end of the third rotating shaft through the connecting plate, a second pulley is fixed on the side wall of the drum of the lifting conveyor, a belt is installed between the first pulley and the second pulley, and a motor drive device is installed on the other side wall of the drum.

[0013] The above technical solution starts the motor drive device, drives the drum to rotate, thereby driving the lifting conveyor to work. At the same time, the rotation of the drum drives the second pulley to rotate, and the rotation of the second pulley drives the first pulley to rotate through the belt, thereby driving the dispersing roller to rotate through the connecting assembly.

[0014] The utility model is further configured such that: the lifting assembly includes two screw lifts symmetrically fixed to the upper end of the baffle, and the screw ends of the screw lifts are fixed to the upper end of the slider.

[0015] With the above technical solution, when it is necessary to raise or lower the dispersing roller, the handwheels of the two screw jacks are turned to raise or lower the screws. The raising or lowering of the screws causes the slider to slide, which in turn raises or lowers the dispersing roller.

[0016] The utility model is further configured such that the same connecting shaft is fixed on the output ends of the two screw jacks.

[0017] With the above technical solution, when it is necessary to drive two screw jacks to work, by rotating the handwheel of one screw jack through the connecting shaft, the other screw jack can be driven to work.

[0018] The utility model is further configured such that several barbs are fixed on the side wall of the dispersing roller.

[0019] The above technical solution can effectively break up tea leaves that have passed through the dispersing roller.

[0020] The utility model is further configured such that several feeding plates are fixed at equal intervals on the conveyor belt of the lifting conveyor.

[0021] The above technical solution can effectively facilitate the transportation of tea leaves.

[0022] The utility model is further configured such that a protective shell is installed on the side wall of the baffle, and the rotating mechanism is located inside the protective shell.

[0023] The above technical solution can protect the rotating mechanism and prevent accidental contact, thereby improving the practicality of this utility model.

[0024] The beneficial effects of this utility model are:

[0025] Compared with existing technologies, the addition of a dispersing roller can disperse the tea leaves, solving the problem of tea leaf accumulation when transported by a lifting conveyor, thus ensuring that the tea leaf selection effect is not affected.

[0026] The presence of barbs effectively disperses tea leaves after they have passed through the dispersing roller.

[0027] By providing a protective shell, the rotating mechanism can be protected, and accidental contact can be prevented, thereby improving the practicality of this utility model. Attached Figure Description

The rotating mechanism includes a connecting component and a rotating component. A lifting component is provided at the upper end of the baffles 2.

[0036] When tea needs to be transported by the lifting conveyor 1, the lifting component is activated to drive the dispersing roller 3 to rise and fall. The distance between the dispersing roller 3 and the belt of the lifting conveyor 1 is adjusted so that the thickness of the tea leaves after passing through the dispersing roller 3 can be adjusted. The rotating component is activated, and the dispersing roller 3 is driven to rotate through the connecting component, so that the tea leaves passing through the dispersing roller 3 can be dispersed to prevent the tea leaves from piling up.

[0037] By incorporating a dispersing roller 3, the tea leaves can be dispersed, thus solving the problem of tea leaf accumulation when transported by the lifting conveyor 1, and ensuring that the tea leaf screening effect is not affected.

[0038] The connecting assembly includes a first bevel gear 6 fixed to the protruding end of the dispersing roller 3 passing through the slider 5, a support plate 7 fixed to the side wall of the slider 5, a first rotating shaft 8 rotatably connected to the upper end of the support plate 7, a second bevel gear 9 meshing with the first bevel gear 6 fixed to the top end of the first rotating shaft 8, a first gear 10 fixed to the protruding end of the first rotating shaft 8 passing through the support plate 7, a connecting plate 11 fixed to the side wall of the baffle 2, a second rotating shaft 12 rotatably connected to the upper end of the connecting plate 11, a second gear 13 meshing with the first gear 10 fixed to the side wall of the second rotating shaft 12, a third bevel gear 14 fixed to the top end of the second rotating shaft 12, a third rotating shaft 15 fixed to the side wall of the connecting plate 11, and a fourth bevel gear 16 meshing with the third bevel gear 14 fixed to the end of the third rotating shaft 15.

[0039] By providing a connecting component, the dispersing roller 3 can be rotated after being raised and lowered. When it is necessary to rotate the dispersing roller 3, the rotating component drives the fourth bevel gear 16 to rotate. The rotation of the fourth bevel gear 16 drives the third bevel gear 14 to rotate. The rotation of the third bevel gear 14 drives the second gear 13 to rotate. The rotation of the second gear 13 drives the first gear 10 to rotate, and at the same time drives the second bevel gear 9 to rotate.

[0052] Working principle:

[0053] When tea needs to be conveyed via the lifting conveyor 1, the handwheels of the two screw jacks 21 are turned to raise and lower the screws.

The distance between the dispersing roller 3 and the belt of the lifting conveyor 1 is adjusted, and the motor drive device 20 is started to drive the drum to rotate, thereby driving the lifting conveyor 1 to work. At the same time, the rotation of the drum drives the second pulley 18 to rotate. The rotation of the second pulley 18 drives the first pulley 17 to rotate via the belt 19, and at the same time drives the fourth bevel gear 16 to rotate. The rotation of the fourth bevel gear 16 drives the third bevel gear 14 to rotate. The rotation of the third bevel gear 14 drives the second gear 13 to rotate. The rotation of the second gear 13 drives the first gear 10 to rotate, and at the same time drives the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 drives the first bevel gear 6 to rotate, thereby driving the dispersing roller 3 to rotate. This can disperse the tea leaves that have passed through the dispersing roller 3, thereby preventing the tea leaves from piling up.
