Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing withering, and particularly relates to a withering machine for tea processing. Background Art

[0002] The freshly picked tea leaves are contaminated with moisture or are still undergoing strong photosynthesis, and need to be withered to reduce the loss of organic substances in the tea leaves and improve the taste of the tea. Tea withering is to spread the freshly picked fresh leaves in a certain thickness and make the fresh leaves show a withered state through sun drying. During the withering process, a series of changes occur to the fresh leaves: the water content decreases, the leaves become soft from brittle and hard, which is convenient for rolling into strips; the activity of the enzyme substances contained in the leaves is enhanced, promoting the decomposition and transformation of fresh leaf components such as starch, protein, and insoluble protopectin, generating effective substances such as glucose, amino acids, and soluble pectin that are beneficial to improving the quality of the made tea, and the polyphenol substances are also oxidized to varying degrees.

[0003] It is found that in the patent document with the publication (announcement) number: CN207721118U, "a withering rack for white tea leaves", it is recorded in the specification: when in use, first draw out the connecting rod from the base to the required length, then fix it with the fastening knob, then hold the crank and rotate the rotating shaft to make the wire reel tighten the steel wire rope, drive the withering rack to turn to the horizontal state, then spread the tea leaves to be dried flat on the screen mesh, after the tea leaves are dried, place a collection container at the bottom, pull out the baffle, and rotate the crank to make the withering rack droop, so that the tea leaves fall into the bottom container under the action of gravity.

[0004] Although this design realizes the function of the withering rack, in the actual use process, when the tea leaves are placed in the sun for natural withering, it is inevitable to encounter sudden weather changes, such as rain. For large-scale tea production, there are many tea leaves to be dried. When encountering weather changes, it is usually too late to collect the tea leaves, which will cause the tea leaves to be wet by rain and reduce the quality of the tea. Summary of the Utility Model

[0013] The rain sensor is connected to the reduction motor through the controller. The rain sensor senses rainwater, transmits the signal to the controller, and controls the reduction motor to start through the controller.

To solve the technical problems existing in this prior art, as disclosed in the background art above, "Although this design realizes the function of the withering rack, in the actual use process, when the tea leaves are placed in the sun for natural withering, it is inevitable to encounter sudden weather changes, such as rain. For large-scale tea production, there are many tea leaves being dried. When the weather changes, it is usually too late to collect the tea leaves, which will cause the tea leaves to be wet by rain and reduce the quality of the tea leaves." In combination with the actual use, this problem is obviously a real and difficult problem to solve. In view of this, to solve this technical problem, a withering machine for tea processing is provided herein.

[0031] As Figures 1-5 shown in the figure;

[0032] Combined with the above content, a pair of withering brackets 2 are fixedly arranged at both ends of the top of the support 1. One end between the two withering brackets 2 is connected and fixed by a support plate 3. A withering support 4 is fixed between the middle parts of the two withering brackets 2. An automatic rain shelter assembly 5 is arranged on the withering bracket 2.

[0033] In an optional embodiment, the automatic rain shelter assembly 5 includes a guiding mechanism 51 and a rain sensor 52 arranged on the withering bracket 2, and a power mechanism 53 fixed on the support plate 3.

[0034] In this embodiment: The rain sensor 52 is connected to the reduction motor 537 through a controller. The rain sensor 52 senses rain and transmits the signal to the controller, and the controller controls the reduction motor 537 to start.

[0035] In an optional embodiment, the guiding mechanism 51 includes a limiting sliding groove 511 opened on the side wall of the withering bracket 2. A limiting sliding block 512 that slides back and forth is arranged inside the limiting sliding groove 511. A T-shaped rod 513 is fixed between the two limiting sliding blocks 512. A rain awning 514 is arranged between the T-shaped rod 513 and the support plate 3.

[0036] In this embodiment: The movement of the limiting sliding block 512 inside the limiting sliding groove 511 drives the rain awning 514 to open and close through the T-shaped rod 513.

[0037] In an alternative embodiment, the power mechanism 53 includes a U-shaped support 531 fixed to the support plate 3. A reciprocating lead screw 532 is movably arranged between the left and right ends of the U-shaped support 531 through bearings, and a pair of slide rods 533 for guiding are provided. A threaded sleeve 534 is screwed onto the reciprocating lead screw 532. A sliding cylinder 535 that slides left and right is sleeved on the slide rod 533. A limit seat 536 is fixedly arranged between the two sliding cylinders 535 and the threaded sleeve 534. The limit seat 536 is fixedly connected to the T-shaped rod 513 through a push rod 538. A reduction motor 537 is installed at the top of the U-shaped support 531, and the output end of the reduction motor 537 is fixedly connected to the reciprocating lead screw 532.

[0038] In this embodiment: The reduction motor 537 drives the reciprocating lead screw 532 to rotate. Since the threaded sleeve 534 is screwed onto the reciprocating lead screw 532, the sliding cylinder 535 is sleeved on the slide rod 533, and both of the two sliding cylinders 535 and the threaded sleeve 534 are fixed to the limit seat 536, the limit seat 536 limits the threaded sleeve 534 and the sliding cylinder 535. At this time, the rotation of the reciprocating lead screw 532 drives the threaded sleeve 534 and the sliding cylinder 535 to perform axial movement in the left and right directions, thereby driving the limit seat 536 to perform reciprocating movement left and right.

[0039] The working principle of the present utility model:

[0040] The rain sensor 52 is connected to the reduction motor 537 through the controller. The rain sensor 52 senses rainwater, transmits the signal to the controller, and controls the reduction motor 537 to start through the controller. At this time, the reduction motor 537 drives the reciprocating lead screw 532 to rotate. Since the threaded sleeve 534 is screwed onto the reciprocating lead screw 532, the sliding cylinder 535 is sleeved on the slide rod 533, and both of the two sliding cylinders 535 and the threaded sleeve 534 are fixed to the limit seat 536, the limit seat 536 limits the threaded sleeve 534 and the sliding cylinder 535. At this time, the rotation of the reciprocating lead screw 532 drives the threaded sleeve 534 and the sliding cylinder 535 to perform axial movement in the left and right directions, thereby driving the limit seat 536 to perform reciprocating movement left and right. By the limit seat 536 pushing the T-shaped rod 513 to move back and forth, the awning 514 is driven to open and close, and the tea leaves placed on the withering bracket 2 can be timely shielded from rain, avoiding the influence of bad weather on the tea leaves.

[0041] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
