Description

Technical Field

[0001] The utility model relates to a tea spreading device, in particular to a tea spreading device for primary tea production, and belongs to the technical field of tea production. Background Art

[0002] Tea leaf spreading is one of the important steps in the initial production of tea, and it belongs to the withering stage. Withering is the process of spreading freshly picked tea leaves evenly on a spreading rack, allowing them to lose some moisture under natural conditions. This process is crucial for the subsequent processing of tea leaves, as it affects the aroma, taste and color of the tea leaves.

[0003] Patent document CN220630928U discloses a tea spreading device for primary tea production, including a spreading frame, a spreading net, a servo motor, a first screw and a first guide rod, etc. The spreading frame is connected to a spreading net, the front left side of the spreading frame is connected to a servo motor, the output shaft of the servo motor is connected to a first screw, and the front right side of the spreading frame is connected to a first guide rod. The spreading plate is adjusted to a specified height through the cooperation between the second screw and the connecting plate, thereby making the thickness of the spread tea more flexible and more applicable, and by directly placing the tea leaves for spreading, there is no need to slowly unload the materials, and the spreading efficiency is high.

[0004] However, although the device can adjust the thickness of the tea leaves and improve the spreading efficiency, it needs to use a servo motor to drive the spreading plate to move back and forth during spreading. The overall structure is too complicated, and the spreading plate is easy to cause pressure on the fresh tea leaves during movement. It does not have a flipping function. In order to ensure the treatment effect, the tea leaves usually need to be turned over manually during the withering process, and the operation efficiency is low. Therefore, a tea spreading device for primary tea production is proposed. Utility Model Content

[0042] like Figure 1-Figure 8 As shown, the embodiment of the utility model provides a tea spreading device for primary tea production, including a frame assembly 1 and a spreading mechanism 2, wherein the frame assembly 1 includes a base 101, a supporting frame 102 and an inner frame 103;

[0044] The spreading mechanism 2 is used to spread the tea leaves by means of vibration and shaking up and down; the spreading mechanism 2 includes a spreading net 201, a storage box 202 and a vibration motor 203;

[0045] The paving net 201 is fixedly connected to the bottom of the inner frame 103, the storage box 202 is fixedly connected to the middle of the inner wall of the paving net 201, and the vibration motor 203 is installed inside the storage box 202;

[0046] The locking mechanism 3 is used to increase the resistance of the inner frame 103 to rotation in the support frame 102, and to control the angle between the inner frame 103 and the support frame 102;

[0047] The covering mechanism 5 is used to cover the upper part of the inner frame 103;

[0048] The locking mechanism 4 is used to connect and fix the covering mechanism 5 and the inner frame 103 .

[0049] In one embodiment, the material spreading mechanism 2 further includes a plurality of spacers 204, and the plurality of spacers 204 are fixedly connected to the upper surface of the spreading net 201;

[0050] The tea leaves at the bottom of the inner frame 103 are blocked by the partition bar 204 so that the tea leaves piled above the partition bar 204 can slide smoothly during the shaking process.

[0051] In one embodiment, the two locking mechanisms 3 each include a connecting sleeve 301, a connecting shaft 302, a gear 303, a plurality of slide grooves 304, a plurality of baffles 305 and a plurality of telescopic springs 306;

[0052] Among them, the connecting shaft 302 is fixedly connected to the middle part of one side of the inner frame 103, the outer side wall of the connecting shaft 302 is rotatably connected to the inner side wall of the supporting frame 102, the gear 303 is fixedly connected to the end of the connecting shaft 302 away from the inner frame 103, the connecting sleeve 301 is fixedly connected to the top of one side of the supporting frame 102, a plurality of sliding grooves 304 are all provided on the inner side wall of the connecting sleeve 301, a plurality of baffles 305 are respectively slidably connected to the inner side walls of the plurality of sliding grooves 304, and a plurality of telescopic springs 306 are respectively fixedly connected between one side of the plurality of baffles 305 and the inner side wall of the sliding groove 304;

[0053] The gear 303 is driven to rotate by the connecting shaft 302 through the inner frame 103, and the rotating gear 303 squeezes the blocking piece 305, so that it slides into the slide groove 304 under the action of pressure and drives the telescopic spring 306 to be compressed. When the gear 303 stops rotating, the compressed telescopic spring 306 drives the blocking piece 305 to slide into the gear 303 and squeeze it to limit its position.

[0054] In one embodiment, the capping mechanism 5 includes a capping frame 501 and a pressing net 502;

[0055] The covering frame 501 is hinged to one side of the upper surface of the inner frame 103, the pressing net 502 is fixedly connected to the inner wall of the covering frame 501, one side of the covering frame 501 and the paving net 201 are fixedly connected to the handle 61, and a side bracket 62 is fixedly connected between the supporting frame 102 and the base 101;

[0056] The covering frame 501 is moved to fit with the inner frame 103 so that the upper part of the inner frame 103 can be shielded by the covering frame 501 in cooperation with the pressing net 502 .

[0057] In one embodiment, the two engaging mechanisms 4 each include a knob 401, a protrusion 402, two engaging shafts 403, two rubber rings 404 and a torsion spring 405;

[0058] The knob 401 is rotatably connected to one side of the inner frame 103, the protrusion 402 is arranged at the top of the knob 401, the two engaging shafts 403 are respectively fixedly connected to one side of the paving net 201 and the covering frame 501, the inner side wall of the knob 401 is slidably connected to the outer side wall of the engaging shaft 403, the two rubber rings 404 are respectively fixedly connected to one side of the outer side wall of the two engaging shafts 403, one end of the torsion spring 405 is fixedly connected to one side of the inner frame 103, and the other end of the torsion spring 405 is fixedly connected to the inner side wall of the knob 401;

[0059] The knob 401 is driven to rotate under the action of pressure through the protrusion 402, and the rotating knob 401 drives the torsion spring 405 to twist. When the covering frame 501 is completely fitted with the inner frame 103, the knob 401 is reset by the twisted torsion spring 405, so that the locking shaft 403 slides into the interior of the knob 401, so as to fix the covering frame 501 on the inner frame 103.

[0060] When the utility model is in operation, the inner frame 103 is opened by moving a handle 61 to drive the covering frame 501 and the pressing net 502 so that tea leaves that need to be spread and withered can be added into the inner frame 103 .

[0061] When the tea leaves need to be spread, the vibration motor 203 is used to drive the storage box 202 to vibrate, and the vibrating storage box 202 drives the spreading net 201 to vibrate as a whole. Then, the other handle 61 is moved to drive the inner frame 103 and the spreading net 201 to shake up and down as a whole, so as to quickly spread the tea leaves on the top of the spreading net 201. The partition bars 204 are provided to block the tea leaves at the bottom of the inner frame 103, so that during the shaking process, the tea leaves piled up above the partition bars 204 can slide smoothly, thereby ensuring the spreading effect.

[0062] When the paving operation is completed, the covering frame 501 is moved to fit with the inner frame 103, and the moving covering frame 501 is used to drive the locking shaft 403 to squeeze the protrusion 402, so that the protrusion 402 drives the knob 401 to rotate under the action of pressure, and the rotating knob 401 drives the torsion spring 405 to twist. When the covering frame 501 is completely fitted with the inner frame 103, the twisted torsion spring 405 drives the knob 401 to reset, so that the locking shaft 403 slides into the interior of the knob 401, so as to fix the covering frame 501 on the inner frame 103, and the rubber ring 404 is provided to increase the friction of the knob 401 to prevent the locking shaft 403 from slipping out of the knob 401 during operation.

[0063] When the drying angle needs to be adjusted, the handle 61 is moved to drive the inner frame 103 to move as a whole. The moving inner frame 103 uses the connecting shaft 302 to drive the gear 303 to rotate. The rotating gear 303 squeezes the baffle 305, so that it slides into the slide groove 304 under the action of pressure and drives the telescopic spring 306 to be compressed, so that the inner frame 103 can rotate smoothly in the supporting stand 102. When the gear 303 stops rotating, the compressed telescopic spring 306 drives the baffle 305 to slide into the gear 303 and squeeze and limit it, so as to increase the resistance of the inner frame 103 during rotation so that it can be maintained at any angle.

[0064] When the tea leaves need to be turned over, the entire tea leaves can be turned over by rotating the inner frame 103 180 degrees. When the tea leaves need to be withered, the knob 401 is turned to separate it from the locking shaft 403, and then the covering frame 501 is moved to separate it from the inner frame 103 to open the inner frame 103 again. Then, the handle 61 is pulled to use the covering frame 501 to drive one side of the inner frame 103 to move, so as to flip the inner frame 103 and pour out the tea leaves directly for collection.

[0065] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
