[0027] The present application will be further described in detail below in combination with the accompanying drawings and related contents: Figures 1-17

[0028] ​The application discloses a high-quality tea drying machine, which comprises a box body 1, first and second drying chambers 10 and 20 arranged on the left and right sides in the box body 1, a guide inlet 11 of a drying net 30 arranged on the bottom of the first drying chamber 10, a lifting support mechanism 40 arranged on the bottom of the first drying chamber 10, a space reserved for the subsequent drying net 30 when the drying net 30 is lifted to the support position by the lifting support mechanism 40, a translation and position changing mechanism 50 arranged on the top of the chamber of the box body 1, the drying net 30 at the top end of the first drying chamber 10 being driven by the translation and position changing mechanism 50 to translate from the first drying chamber 10 to the top of the second drying chamber 20, a guide outlet 21 of the drying net 30 arranged on the bottom of the second drying chamber 20, and a support and release mechanism 60 arranged on the bottom of the second drying chamber 20, wherein the support and release mechanism 60 comprises a movable rod or plate 61 arranged at a support position of the second last drying net 30 on the bottom of the second drying chamber 20 or a avoiding position separated from the second last drying net 30 on the bottom of the second drying chamber 20.

[0029] In the above scheme, the tea leaves to be treated are arranged on the drying nets 30. The drying net 30 containing the tea leaves is pushed into the space reserved for the drying net 30 on the bottom of the first drying chamber 10 from the guide inlet 11 on the bottom of the first drying chamber 10, and the tea leaves on the drying net 30 are dried under the heating of a heat source. Then the drying net 30 on the bottom of the first drying chamber 10 is lifted to the support position by the lifting support mechanism 40, and the above process is repeated, so that the drying nets 30 in the first drying chamber 10 are gradually lifted in a stacked manner. It should be noted that a certain number of drying nets 30 are previously arranged in the second drying chamber 20 in a stacked manner, and the drying nets 30 do not contain tea leaves. The top end of the drying net 30 in the second drying chamber 20 is lower than the top end of the drying net 30 in the first drying chamber 10 by one net position. After the drying process of the drying net 30 containing the tea leaves in the first drying chamber 10 is completed, the drying net 30 at the top end of the first drying chamber 10 is driven by the translation and position changing mechanism 50 to translate from the first drying chamber 10 to the top end of the drying net 30 in the second drying chamber 20, so that the tea leaves are treated for aroma extraction in the second drying chamber 20. The support of the second last drying net 30 on the bottom of the second drying chamber 20 by the movable rod or plate 61 enables the lowest drying net 30 in the second drying chamber 20 to be in a free state without being pressed by the upper drying nets 30, so that the drying net 30 can be easily taken out from the second drying chamber 20 at the guide outlet 21. Then the movable rod or plate 61 is controlled to be in the avoiding position separated from the second last drying net 30 on the bottom of the second drying chamber 20, and the stacked drying nets 30 in the second drying chamber 20 can naturally fall down, so that the above process is repeated, the drying nets 30 containing the tea leaves in the first drying chamber 10 are sequentially transferred into the second drying chamber 20 for aroma extraction, and the drying nets 30 in the second drying chamber 20 are sequentially taken out from the guide outlet 21 on the bottom, thereby completing the aroma extraction of the tea leaves.

[0030] In the present scheme, the left and right sides in the box 1 are provided with a first drying chamber 10 for drying and a second drying chamber 20 for aroma extraction, drying and aroma extraction are concentrated in the same box 1, and the tea drying net 30 placed in the box 1 is transported between the two drying chambers by the translational indexing mechanism 50 in the box 1, without taking out the tea drying net 30 for transportation, reducing heat loss, and the whole machine is easy to operate and occupies small space. In addition, the tea leaves after aroma extraction are removed from the guide outlet 21 at the bottom of the second drying chamber 20 in sequence with the tea drying net 30, and the tea leaves on the bottom tea drying net 30 are not affected by the upward flow of the moisture volatilized from the tea leaves on the upper tea drying net 30, so that the tea leaves removed in sequence have basically the same drying degree, ensuring the quality of the final tea drying and aroma extraction processing.

[0031] Further, in order to ensure that the tea drying net 30 placed in the space at the bottom of the first drying chamber 10 will not fall off, the left and right sides of the first drying chamber 10 are provided with a first supporting plate 12 in the form of a strip plate with a flat surface, the front end of the first supporting plate 12 is connected or closely connected with the bottom edge of the guide inlet 11, and the rear end of the first supporting plate 12 extends to the rear wall of the first drying chamber 10. The first supporting plate 12 can support the tea drying net 30 placed in the space at the bottom of the first drying chamber 10, avoiding the tea drying net 30 from falling down.

[0032] As a preferred scheme, the rod top of the supporting rod 44 is lower than or equal to the height of the first supporting plate 12 when the supporting rod 44 is in the low position. The upward and downward movement of the supporting rod 44 can lift the tea drying net 30 placed in the space at the bottom of the first drying chamber 10 to the supporting position, so that a space is reserved below the tea drying net 30 for subsequent placement of the tea drying net 30. Here, by setting the height of the supporting rod 44 in the low position relative to the height of the first supporting plate 12, interference between the supporting rod 44 and the subsequent tea drying net 30 can be avoided, ensuring that the tea drying net 30 can be normally placed in the first drying chamber 10.

[0033] Further, a groove-shaped recess 121 is provided on the surface of the first supporting plate 12, the length direction of the supporting rod 44 is perpendicular to the length direction of the first supporting plate 12, and the depth of the recess 121 is greater than or equal to the diameter of the supporting rod 44 in the upward and downward directions. When the supporting rod 44 is in the low position, it is located in the recess 121, and the inner cavity of the recess 121 can serve as a space for accommodating the supporting rod 44. At the same time, by setting the diameter of the supporting rod 44, the supporting rod 44 can be completely accommodated in the recess 121 without affecting the placement of the subsequent tea drying net 30.

[0034] In combination Figure 3 , 8As shown in FIG. 9, the inner end of the supporting rod 44 is fixedly connected with the upper end of the vertical rod 43, and the two ends of the horizontal first longitudinal rod 42 are respectively provided with the vertical rod 43 and the supporting rod 44, and the first longitudinal rod 42 is driven to move up and down by the lifting mechanism. When the first longitudinal rod 42 moves up, the vertical rods 43 and the supporting rods 44 at the two ends of the first longitudinal rod 42 move up synchronously, and the drying net 30 placed on the bottom of the first drying chamber 10 can be lifted to the supporting position. The supporting rods 44 are symmetrically distributed at four positions on the opposite sides of the first drying chamber 10, and the lifting stability of the drying net 30 is improved.

[0035] As a preferred solution, the upper side of the first supporting plate 12 is provided with a stop supporting plate 100, and the outer side of the stop supporting plate 100 is hingedly connected with a hinge shaft 101. The stop supporting plate 100 can be in an avoiding position in which the plate surface is placed outside the outer frame of the drying net 30 or in a stopping position in which the plate surface is placed on the bottom of the frame of the drying net 30. The drying net 30 is placed in the space between the stop supporting plate 100 and the first supporting plate 12 and enters the first drying chamber 10. When the supporting rod 44 lifts the drying net 30 to move up, the lower end of the stop supporting plate 100 is pushed by the bottom drying net 30 and is turned to the avoiding position outside the outer frame of the drying net 30, so that the bottom drying net 30 can move up to the position above the stop supporting plate 100 without being blocked. Then, the stop supporting plate 100 falls back to the stopping position in which the plate surface is placed on the bottom of the frame of the drying net 30, so that the drying net 30 lifted in the first drying chamber 10 can be supported as a whole. In this way, space for placing the subsequent drying net 30 can be reserved.

[0036] Further, the middle part of the first longitudinal rod 42 is provided with a first lifting rod 41 extending downward, one end of the first power rotating shaft 80 is connected with the first crank 45, the other end of the first crank 45 is hingedly connected with one end of the first connecting rod 46, the other end of the first connecting rod 46 is hingedly connected with the connection position of the first longitudinal rod 42 and the first lifting rod 41, and the limiting wheel set 70 limits the up-down translation path of the first lifting rod 41. In this solution, the first power rotating shaft 80 is driven to rotate, the first crank 45 is swung, the first connecting rod 46 pushes the first lifting rod 41 and the first longitudinal rod 42 on the first lifting rod 41 to move up and down, and the supporting rod 44 can lift the drying net 30. The limiting wheel set 70 limits the movement of the first lifting rod 41, so that the first lifting rod 41 can stably move up and down in the vertical direction. In this solution, as shown in FIG. 10, the limiting wheel set 70 can be composed of guide wheels clamped on both sides of the first lifting rod 41, the guide wheels are provided with limiting grooves, and the first lifting rod 41 is located in the limiting grooves to limit the horizontal movement of the first lifting rod 41. Figure 9

[0037] ​Since the hinge shaft cores at both ends of the first connecting rod 46 are parallel to the shaft core of the first power rotating shaft 80, the first lifting rod 41 only makes displacement in the vertical direction and cannot rotate around its own rod core, thus ensuring that the supporting rod 44 only makes translational movement in the vertical direction. In addition, the first lifting rod 41 can also be a I-shaped steel or a square rod, which cooperates with the limiting wheel set 70 to limit the rotation freedom of the first lifting rod 41 around its own rod core.

[0038] As shown in Figure 3 、 7 , 8, in order to ensure that the drying net 30 at the lowest position in the second drying chamber 20 is at a height position corresponding to the guide outlet 21, a second supporting plate 22 in the form of a strip plate with a flat surface is arranged on the left and right sides of the second drying chamber 20. The front end of the second supporting plate 22 is connected or closely connected to the bottom edge of the guide outlet 21, and the rear end of the second supporting plate 22 extends to the rear wall of the second drying chamber 20. The drying net 30 at the lowest position in the second drying chamber 20 is placed on the second supporting plate 22, and all the drying nets 30 stacked above the drying net 30 at the lowest position in the second drying chamber 20 are supported by the second supporting plate 22.

[0039] As a preferred solution, two second power rotating shafts 62 are arranged in the second drying chamber 20 and are parallel to each other, have the same height, and are arranged horizontally. The movable rods or plates 61 with a flat surface are cantilevered and fixed on the second power rotating shafts 62. When the movable rods or plates 61 rotate with the second power rotating shafts 62, the movable rods or plates 61 are at a position avoiding the frame peripheral surface of the drying net 30 when the drying net 30 is stacked, or are at a position inserted into the frame bottom edge of the drying net 30 at the second-to-last position at the bottom of the second drying chamber 20 and supporting the second-to-last drying net 30 and the drying nets 30 above it to the supporting position. By controlling the rotation of the second power rotating shafts 62, the movable rods or plates 61 can be swung upward. The overhanging end of the movable rods or plates 61 can support the second-to-last drying net 30 in the second drying chamber 20, so that the drying net 30 at the lowest position in the second drying chamber 20 can be separated from the drying nets 30 above it, and the drying net 30 at the lowest position is free from the cumulative pressure of the drying nets 30 above it and becomes a free state, which facilitates removal from the guide outlet 21. Then, the movable rods or plates 61 can be controlled to swing downward to a position avoiding the drying net 30, so that the movable rods or plates 61 do not interfere with the drying net 30, and the subsequent drying net 30 in the second drying chamber 20 can immediately fall to a position corresponding to the guide outlet 21 and be easily removed from the guide outlet 21. As shown in Figure 14 、 15 , 8, in order to ensure that the drying net 30 at the lowest position in the second drying chamber 20 is at a height position corresponding to the guide outlet 21, a second supporting plate 22 in the form of a strip plate with a flat surface is arranged on the left and right sides of the second drying chamber 20. The front end of the second supporting plate 22 is connected or closely connected to the bottom edge of the guide outlet 21, and the rear end of the second supporting plate 22 extends to the rear wall of the second drying chamber 20. The drying net 30 at the lowest position in the second drying chamber 20 is placed on the second supporting plate 22, and all the drying nets 30 stacked above the drying net 30 at the lowest position in the second drying chamber 20 are supported by the second supporting plate 22. Figure 14 , Figure 15The activity rod or plate 61 is shown in the state of supporting the drying net 30, that is, the lowest drying net 30 and the second lowest drying net 30 form a height difference h of 1-5 mm, the second lowest drying net 30 is not pressed on the lowest drying net 30, and the lowest drying net 30 can be conveniently moved and taken out.

[0040] As a preferred solution, the second power shaft 62 is arranged near and parallel to the front and rear walls of the box, and the second power shaft 62 in the front is located on the inner side of the upper opening of the guide outlet 21. When the activity rod or plate 61 rotates to the supporting position of the second lowest drying net 30, the activity rod or plate 61 avoids the guide path of the first lowest drying net 30 below it. In this solution, the second power shaft 62 is arranged on the front and rear walls of the second drying chamber 20, and the drying net 30 is located in the area between the two second power shafts 62. The activity rod or plate 61 supports or avoids the front and rear frame edges of the drying net 30. The example shown in the figure is that the square activity plate 61 is arranged on the second power shaft 62, and the long side plate edge of the activity plate 61 is fixed on the second power shaft 62. For the sake of brevity, the activity plate 61 is described below.

[0041] When the activity plate 61 supports the second lowest drying net 30 to the supporting position, the activity plate 61 and the lowest drying net 30 in the second drying chamber 20 avoid each other and do not interfere with each other, and the lowest drying net 30 can be smoothly moved out through the guide outlet 21.

[0042] Further, in combination with Figure 8 , 10As shown in Figure 11, the shaft end of the second power shaft 62 is connected to one end of the second crank 66, and the other end of the second crank 66 is hinged to one end of the second connecting rod 67. The other end of the second connecting rod 67 is hinged to the upper end of the vertically arranged vertical rod 65. The two ends of the horizontally oriented second longitudinal rod 64 are respectively arranged with vertical rods 65 and corresponding to the shaft ends of the two second power shafts 62. The second longitudinal rod 64 is driven by the lifting mechanism to move up and down. By driving the second longitudinal rod 64 to move up and down through the lifting mechanism, the vertical rod 65 on it can move up and down synchronously. Furthermore, the vertical rod 65, connected by the second connecting rod 67, can drive the second crank 66 to swing, so that the second power shaft 62 connected to it can rotate around its own axis. The movable plate 61 arranged on the second power shaft 62 can then swing to support or avoid the second-to-last drying screen 30 in the second drying chamber 20. It should be noted that the two second power shafts 62 are controlled by two symmetrically arranged second cranks 66 to rotate synchronously in opposite directions, so that the movable plates 61 located on the front and rear sides of the drying screen 30 synchronously support the drying screen 30, and the drying screen 30 can be stably supported. In addition, in this solution, the second longitudinal rod 64 can be driven to move up and down in the same way as the first longitudinal rod 42. The first power shaft 80, as a power output component, can extend from the first drying chamber 10 into the second drying chamber 20, and drive the first longitudinal rod 42 and the second longitudinal rod 64 to move up and down synchronously in a coaxial manner. This will not be elaborated further here.

[0043] To better illustrate the changes in the state of the second connecting rod 67 and the second crank 66 during motion, such as Figure 11 As shown in the figure, the dashed line indicates the position of the second vertical rod 64 when it rises to the high position and the corresponding position of the corresponding component.

[0044] Combination Figure 5 , 6 As shown, the translation and transfer mechanism 50 includes a push plate 54. The push plate 54 is initially positioned to the left of the uppermost drying screen 30 in the first drying chamber 10. When the push plate 54 moves, it pushes the uppermost drying screen 30 of the first drying chamber 10 towards the uppermost drying screen 30 in the second drying chamber 20. Since the drying screen 30 at the top of the second drying chamber 20 is one screen lower than the drying screen 30 at the top of the first drying chamber 10, when the tea leaves on the drying screen 30 at the top of the first drying chamber 10 have been dried for the set time, the push plate 54 can push the drying screen 30 towards the top of the second drying chamber 20, thereby pushing the drying screen 30 at the top of the first drying chamber 10 into the second drying chamber 20 for further drying and aroma enhancement. The drying screen 30 does not need to be removed from the housing 1 and can be directly transferred between the two drying chambers, making the transfer of the drying screen 30 more convenient and preventing significant heat loss.

[0045] Further, in the present scheme, a transmission chain 52 is arranged at the top of the chamber of the cabinet 1, the wheel core of the chain wheel of the transmission chain 52 is perpendicular to the front and back cabinet walls of the cabinet 1, when arranging the transmission chain 52, a mounting cover 51 is arranged at the top end of the cabinet 1, and the transmission chain 52 and the chain wheel can be arranged in the mounting cover 51. The connecting seat 53 comprises an upper plate 531 fixedly connected with the lower section chain body of the transmission chain 52, the left end of the upper plate 531 has a vertical plate 532 extending downward, and the upper edge of the push plate 54 is hingedly connected at the corner top position of the right angle region clamped by the upper plate 531 and the vertical plate 532. When the push plate 54 returns to the initial position, the upper end of the push plate 54 can be deflected about the horizontal hinge shaft 541, so that the plate body of the push plate 54 can swing to the upper side of the drying net 30 and continue to move, and the push plate 54 will not be rigidly pressed with the drying net 30 and can be normally reset. When the push plate 54 returns to the initial position, under the action of gravity, the plate body thereof can naturally fall back to the plumb direction, so that it can again push the drying net 30 to move to the top of the second drying chamber 20. It should be noted that, since the upper edge of the push plate 54 is hingedly connected at the corner top position of the right angle region clamped by the upper plate 531 and the vertical plate 532, when the push plate 54 pushes the drying net 30, the plate body thereof will abut against the vertical plate 532 and will not be deflected, so that it can normally push the drying net 30 to move and will not be hindered by the drying net 30 when returning.

[0046] In combination Figure 1 , 3 , 8, 16, 17, considering that the drying net 30 can be conveniently pushed into the guide inlet 11 or moved out of the guide outlet 21, the rear end of the platform 110 located at the front side of the cabinet 1 and having a flat plate surface is connected or closely connected with the outer bottom of the guide inlet 11 and the guide outlet 21, and the first and second moving mechanisms 200A and 200B are separately arranged on the platform 110, the first moving mechanism 200A drives the drying net 30 to translate from the guide inlet 11 to the reserved insertion space at the bottom of the first drying chamber 10, and the second moving mechanism 200B drives the drying net 30 at the bottom end of the second drying chamber 20 to translate from the guide outlet 21 to the outside of the cabinet 1. Through the arrangement of the first and second moving mechanisms 200A and 200B, the drying net 30 can be automatically pushed into the first drying chamber 10 or moved out of the guide outlet 21 in the second drying chamber 20, which can not only reduce the labor output, but also avoid the high-temperature scalding of the human body at the guide inlet 11 or the guide outlet 21 compared with the manual moving mode.

[0047] As a preferred solution, the first and second guide plate slots 201A, 201B horizontally arranged on the table 110 extend from the front end of the table 110 to the guide inlet 11 and the guide outlet 21 respectively, and the first and second movable seats 202A, 202B connected with the conveying chain 207 are respectively arranged in the first and second guide plate slots 201A, 201B to form a guide and limiting cooperation, the first push plate 203A moves with the first movable seat 202A between the front edge of the table 110 and the guide inlet 11, and the second push plate 203B moves with the second movable seat 202B between the front edge of the table 110 and the inner side wall of the front frame rod of the last drying net 30 in the second drying chamber 20. In this solution, the drying net 30 to be placed in the first drying chamber 10 is placed on the table 110 in the region between the first push plate 203A and the guide inlet 11, and the first movable seat 202A is driven by the conveying chain 207 to move to the guide inlet 21, so that the first push plate 203A pushes the drying net 30 to move into the first drying chamber 10. When the second movable seat 202B is driven by the conveying chain 207 to move from the inner side wall of the front frame rod of the last drying net 30 in the second drying chamber 20, the second push plate 203B pushes the last drying net 30 in the second drying chamber 20 to move out of the guide outlet 21 to the table 110.

[0048] Further, the middle and upper part of the first push plate 203A standing on the plate body is hingedly connected to the front upper edge of the first movable seat 202A, the axis core of the hinge shaft is horizontally and perpendicularly to the displacement direction of the first movable seat 202A, the upper end of the first push plate 203A protrudes from the table 110 and the protruding height is less than the distance between the upper and lower frame surfaces of the drying net 30, so as to avoid that the upper end of the first push plate 203A is too high to interfere with the upper edge of the guide inlet 11 during movement. In this solution, the upper edge of the guide inlet 11 can be hingedly connected with a baffle (not shown in the figure), and the baffle can shield the guide inlet 11 to avoid the loss of a large amount of hot air in the box 1 through the guide inlet 11. On this basis, the first push plate 203A is hingedly connected to the front upper edge of the first movable seat 202A, when the first push plate 203A pushes the drying net 30 to move into the guide inlet 11, on the one hand, the frame edge of the drying net 30 can naturally push the baffle to flip, so that the baffle does not hinder the advancement of the drying net 30; on the other hand, when the first movable seat 202A returns, the plate body of the first push plate 203A is blocked by the baffle and flips to a horizontal direction to avoid the baffle, so that the first push plate 203A can smoothly return with the first movable seat 202A. It should be noted that under the action of gravity, the lower half of the first push plate 203A naturally abuts against the front side of the first movable seat 202A.

[0049] Further, the middle and upper part of the second push plate 203B is hingedly connected to the upper edge of the rear side of the second movable seat 202B, the axis core of the hinge shaft is horizontally and perpendicularly to the displacement direction of the second movable seat 202B, the upper end of the second push plate 203B protrudes from the table top 110 and the protruding height is less than the distance between the frame and the lower frame surface of the screen body of the drying screen 30, so as to avoid the interference between the second push plate 203B and the screen body of the drying screen 30 during the movement. In this scheme, the second push plate 203B is hingedly connected to the upper edge of the rear side of the second movable seat 202B, when it is needed to take out the drying screen 30 at the bottom of the second drying chamber 20, the second movable seat 202B is controlled to move towards the guide outlet 21, the plate body of the second push plate 203B will be pressed against the front frame rod of the bottom drying screen 30, so that the plate body of the second push plate 203B is naturally turned to be horizontally away from the front frame rod of the drying screen 30, with the continuous movement of the second movable seat 202B, the second push plate 203B can be immediately moved to the inner rod surface side position of the front frame rod of the bottom drying screen 30. At this time, the second push plate 203B is naturally turned to be plumb under the action of the gravity of the lower half of the body, when the second movable seat 202B is controlled to move towards the front edge of the table top 110, the second push plate 203B can push the inner side rod surface of the front frame rod of the lowest drying screen 30, so that the drying screen 30 can be moved outwards through the guide outlet 21. In this way, the second push plate 203B can avoid the movement interference with the drying screen 30 and can normally move out the drying screen 30 at the bottom of the second drying chamber 20.

[0050] As a preferred solution, the left and right sides of the first movable seat 202A and the second movable seat 202B are arranged with the guiding frames 204 which are vertically arranged and parallel to each other, the upper frame bars of the guiding frames 204 are at the same height as the table plate 110 or lower than the height of the table plate 110, so as to avoid the motion interference with the movement of the drying net 30 on the table plate 110. The guiding frames 204 cooperating with the first movable seat 202A and the second movable seat 202B respectively extend from the front end of the table plate 110 to the inner side of the guiding entrance 11 and the guiding exit 21, the left and right sides of the first movable seat 202A and the second movable seat 202B are connected with the support rollers 206a whose wheel cores are horizontally arranged, the support rollers 206a are located in the guiding track holes 205 on the guiding frames 204 and form rolling cooperation with the lower hole walls, the first movable seat 202A and the second movable seat 202B are connected with the limiting rollers 206b whose wheel cores are located in the plumb direction, the limiting rollers 206b are located between the upper and lower frame bars of the guiding frames 204 and form rolling cooperation with the upper and lower frame bars of the guiding frames 204. The two guiding frames 204 arranged symmetrically and at intervals form the moving path for the first and second movable seats 202A and 202B, the cooperation between the support rollers 206a and the guiding track holes 205 on the guiding frames 204 can support the first and second movable seats 202A and 202B and enable them to move along the extension direction of the guiding track holes 205, and the cooperation between the limiting rollers 206b and the frame bars of the guiding frames 204 can limit the horizontal deviation of the first and second movable seats 202A and 202B, and the common arrangement of the support rollers 206a and the limiting rollers 206b can ensure that the first and second movable seats 202A and 202B are stably limited on the guiding frames 204 to move, so as to enable the first and second poking plates 203A and 203B to normally push the drying net 30 on the table plate 110.
