[0037] 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.

[0038] like Figure 1As shown, the present invention provides a foldable lifting tea withering machine, including a base frame 1 and a lifting mechanism 2 installed on the base frame 1, a foldable withering table 3 is installed on the telescopic structure of the lifting mechanism 2, and an oscillating fan 4 is installed on the base frame 1, and the wind direction generated by the oscillating fan 4 is toward the foldable withering table 3.

[0039] Among them, the foldable withering table 3 includes a main withering table 31 installed on the telescopic structure of the lifting mechanism 2, and at least one auxiliary withering table 32 arranged on both sides of the main withering table 31 and capable of moving along the side surface of the main withering table 31. A stepping drive assembly 33 is provided under each auxiliary withering table 32. The stepping drive assembly 33 drives the auxiliary withering table 32 to extend and open to both sides of the main withering table 31 or to shrink toward the center of the main withering table 31 to adjust the total withering table area of ​​the foldable withering table 3.

[0040] This embodiment can improve space utilization and withering requirements at different heights by setting up a lifting mechanism and a folding mechanism, thereby achieving the maximum withering amount, increasing the withering efficiency, and adapting to different withering methods and withering environments; at the same time, after withering is completed, it can save storage space and solve problems such as difficulty in moving the whole machine and site problems.

[0041] Specifically, if it is necessary to increase the withering efficiency, the lifting mechanism 2 lowers the height of the foldable withering table 3, and uses the oscillating fan 4 to wither the tea leaves on the foldable withering table 3. If it is necessary to reduce the withering efficiency, the lifting mechanism 2 increases the height of the foldable withering table 3.

[0042] Similarly, if the withering amount needs to be increased, the stepping drive assembly 33 drives the auxiliary withering table 32 to extend and open to both sides of the main withering table 31. If the withering amount needs to be reduced, the stepping drive assembly 33 drives the auxiliary withering table 32 to shrink toward the center of the main withering table 31.

[0043] Furthermore, an air flow guide plate 8 is installed above the oscillating fan 4, and the air flow guide plate 8 is used to expand the blowing range of the oscillating fan 4. The use of the air flow guide plate 8 can expand the blowing range generated by the oscillating fan 4 to the total withering table area of ​​the foldable withering table 3.

[0044] As an implementation method of this embodiment, the lifting mechanism 2 includes an articulated bracket arranged between the main withering table 31 and the two sides of the base frame 1, wherein the articulated bracket includes a first articulated link 21 movably hinged between the connecting rod fixing plate of the base frame 1 and the connecting rod fixing plate of the main withering table 31, and a second articulated link 22 connected to the first articulated link 21 through a joint axis, and both ends of the second articulated link 22 move on the base frame 1 and the main withering table 31 through bearings respectively.

[0045] A force rod 23 is installed on the second hinged connecting rod 22, and a hydraulic cylinder 24 is movably installed on another connecting rod fixing plate on the base frame 1, and the front end of the hydraulic cylinder 24 is movably installed on the force rod 23. The hydraulic cylinder 24 pushes the force rod 23 to move upward, so that the main withering table 31 can move vertically.

[0046] The first hinged link 21 includes a lower inner link connected to the link fixing plate on the base frame 1 through a support rod tail end pin, and an upper outer link movably connected to the upper end of the lower inner link, and the upper end of the upper outer link is movably hinged on the link fixing plate of the main withering table 31.

[0047] The second articulated link 22 includes a bottom bracket cross-connected to the lower inner link via a joint axis, and an upper bracket movably connected to the upper end of the bottom bracket, the upper bracket is cross-connected to the upper outer link via a joint axis, and the lower end of the bottom bracket moves along the surface of the base frame 1 via a bearing, and the upper end of the upper bracket moves along the main withering table 31 via a bearing.

[0048] When the height of the foldable withering table 3 is lowered by utilizing the lifting mechanism 2, the hydraulic cylinder 24 is adjusted to pull the force rod 23 downward, the bearing at the lower end of the bottom bracket moves along the surface of the base frame 1, and the upper end of the upper bracket moves along the surface of the main withering table 31 through the bearing. The hinge angle between the bottom bracket and the upper bracket becomes smaller, and similarly, the hinge angle between the lower inner connecting rod and the upper outer connecting rod becomes smaller, thereby pulling the foldable withering table 3 downward.

[0049] When the height of the foldable withering table 3 is increased by utilizing the lifting mechanism 2, the hydraulic cylinder 24 is regulated to push the force rod 23 upward, and the hinge angle between the bottom bracket and the upper bracket becomes larger. Similarly, the hinge angle between the lower inner connecting rod and the upper outer connecting rod becomes larger, thereby pushing the foldable withering table 3 to move upward.

[0050] In order to further improve the stability of adjusting the height of the foldable withering table 3 , a driving gear assembly 5 for assisting the lifting mechanism 2 to change the overall height of the foldable withering table 3 is installed on the lower surface of the main withering table 31 .

[0051] like Figure 2 and Figure 3 As shown, the driving gear assembly 5 includes a gear motor 51 installed on the lower surface of the main withering table 31, and a threaded straight tube 52 installed on the lower surface of the main withering table 31. The gear motor 51 drives the threaded straight tube 52 to rotate through a gear combination.

[0052] A screw base 53 is installed on the threaded straight tube 52, and the screw base 53 can move linearly along the threaded straight tube 52. The screw base 53 is used to support the movement of the bearing at the upper end of the upper bracket to assist the lifting mechanism 2 to change the overall height of the foldable withering table 3.

[0053] When the gear motor 51 drives the threaded straight tube 52 to rotate through the gear combination, the screw base 53 uses the screw principle to move linearly along the threaded straight tube 52. The screw base 53 is used to resist the movement of the bearing at the upper end of the upper bracket to assist the lifting mechanism 2 in changing the overall height of the foldable withering table 3.

[0054] The implementation principle of the gear combination is specifically as follows: a large gear 54 is installed at the end of the threaded straight tube 52, and a small gear 55 is installed at the end of the gear motor 51. The gear motor 51 drives the large gear 54 to rotate through the small gear 55 to drive the entire threaded straight tube 52 to rotate, and the screw base 53 can move linearly along the threaded straight tube 52, so that the screw base 53 moves against the bearing at the upper end of the upper bracket.

[0055] After adjusting the overall height of the foldable withering table 3, it is necessary to further adjust the withering area of ​​the foldable withering table 3. The stepping drive assembly 33 includes a stepping motor 331 installed on the side of the auxiliary withering table 32, and a screw module connected to the output shaft of the stepping motor 331. The lower surface of the screw module drives the auxiliary withering table 32 to extend and open to both sides of the main withering table 31 or to contract toward the center of the main withering table 31 through the friction between the lower surface of the screw module and the upper surface of the main withering table 31 below the auxiliary withering table 32, thereby adjusting the overall withering area composed of the auxiliary withering table 32 and the main withering table 31.

[0056] like Figure 4 As shown, the screw module includes a screw shaft 333 connected to the output shaft of the stepper motor 331 through a coupling 332, and a clamp pushing plate 334 mounted on the screw shaft 333. The stepper motor 331 drives the screw shaft 333 to rotate, and the clamp pushing plate 334 can move linearly along the screw shaft 333 to drive the auxiliary withering table 32 to move.

[0057] Similarly, the stepping drive assembly 33 still utilizes the lead screw principle to adjust the rotational action generated by the stepper motor 331 into the linear movement of the clamp pushing plate 334. It should be particularly noted that a roller is provided on the lower surface of the clamp pushing plate 334. Therefore, friction is generated between the clamp pushing plate 334 and the main withering table 31 or the auxiliary withering table 32 located below the current auxiliary withering table 32 to push the current auxiliary withering table 32 to expand outward or contract inward.

[0058] In order to improve the stability of the auxiliary withering table 32 when it expands outward or contracts inward, the outer surface of the auxiliary withering table 32 is provided with a slide groove 6, and the inner surface of the main withering table 31 is also provided with a slide groove 6, and the front end of the slide groove 6 of the auxiliary withering table 32 is provided with a guide rod 7. The auxiliary withering table 32 and the main withering table 31 are mutually locked through the guide rod 7 and the slide groove 6, so that the auxiliary withering table 32 can move linearly along the main withering table 31.

[0059] When there are only two auxiliary withering tables 32 and they are distributed on both sides of the main withering table 31, the guide rod 7 at the front end of the slide groove 6 of the auxiliary withering table 32 is inserted into the slide groove 6 on the inner surface of the main withering table 31, and the lower surface of the auxiliary withering table 32 is provided with a stepping drive assembly 33, and the clamp pushing plate 334 pushes the current auxiliary withering table 32 to expand outward or contract inward through the friction between the upper surface of the main withering table 31.

[0060] When there are four auxiliary withering tables 32 and they are distributed on both sides of the main withering table 31, the guide rod 7 at the front end of the chute 6 of the first auxiliary withering table 32 is inserted into the chute 6 on the inner surface of the main withering table 31, and the guide rod 7 at the front end of the chute 6 of the second auxiliary withering table 32 is inserted into the chute 6 of the first auxiliary withering table 32.

[0061] A stepping drive assembly 33 is provided on the lower surface of the first auxiliary withering table 32, and the clamp pushing plate 334 pushes the first auxiliary withering table 32 to expand outward or contract inward through the friction between the clamp pushing plate 334 and the upper surface of the main withering table 31.

[0062] A stepping drive assembly 33 is provided on the lower surface of the second auxiliary withering table 32, and the clamp pushing plate 334 pushes the second auxiliary withering table 32 to expand outward or contract inward through the friction between the clamp pushing plate 334 and the upper surface of the first auxiliary withering table 32.

[0063] When withering the tea leaves, all the auxiliary withering stages 32 are uniformly expanded outwards, and when withering of the tea leaves is completed, all the auxiliary withering stages 32 are uniformly contracted inwards.

[0064] In order to facilitate the movement of the entire tea withering machine, a moving mechanism 9 is installed on the lower surface of the base frame 1. The moving mechanism 9 includes a driving motor group 91 installed on the base frame 1, and rollers 92 installed at four corner positions of the lower surface of the base frame 1. The motor gear on the driving motor group 91 is engaged with the roller 92 through a belt to drive the roller 92 to rotate.

[0065] The specific method of using the above-mentioned tea withering machine is: provide power to the driving motor group to drive the motor gear, the motor gear and the roller gear are connected by a belt, the roller gear rotates under the drive of the motor gear, and then drives the roller and tire to move the whole machine.

[0066] After determining the position, the gear motor of the main withering table is then started, and the gear motor provides power to the gear combination, which is connected to the threaded straight tube. Since one end of the upper bracket is provided with a bearing, a threaded straight tube base and a threaded straight tube bottom frame, when the gear motor drives the gear to operate, the threaded straight tube drives the connected threaded straight tube base and the threaded straight tube bottom frame to contract and move under the operation of the gear, thereby causing the upper bracket with the bearing to move horizontally, thereby adjusting the height of the main withering table.

[0067] After the height of the main withering table is determined, the advancing motor of the auxiliary withering machine is started to drive the screw module, so that the auxiliary withering table, which is slidingly embedded with the main withering table, moves under the drive of force, and the symmetrical auxiliary withering table operates in the same way; when it reaches the preset good position, the second-layer auxiliary withering table is translated as mentioned above, and the table top is unfolded, and the tea leaves can be placed on it for withering.

[0068] When the tea leaves are withering, you can also choose whether to use the oscillating fan below to assist with withering; withering methods suitable for different environments, indoor withering, sunlight withering, etc.; after withering is completed, the withering table is lowered to collect the tea leaves by adjusting the height, and then the withering table is retracted to determine the end height and move the whole machine to the designated storage location, thereby improving space utilization and saving labor.

The protection scope of the present application is defined by the claims.
