Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, specifically to a device for spreading, cooling, and turning fresh tea leaves. Background Technology
[0002] Spreading out fresh tea leaves is a crucial step in the initial post-harvest processing. By spreading them thinly in a cool, ventilated place, they naturally lose moisture, lower the leaf temperature, soften the leaf texture, regulate enzyme activity, and promote the transformation of internal components, laying the foundation for subsequent processes such as fixation and rolling. Different types of tea require adjustments to the spreading time and environmental conditions.
[0003] In existing technologies, when spreading fresh tea leaves to dry, the tea leaves are usually laid flat on containers such as bamboo mats or bamboo trays. Every once in a while, the tea leaves need to be turned over to ensure that the upper and lower layers of tea leaves lose moisture evenly. If the container is large, the operator needs to walk around the container and continuously turn the leaves over at different positions on the top of the container, which is quite labor-intensive. Therefore, a fresh tea leaf spreading and turning device is proposed to solve the above problems. Utility Model Content
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A fresh tea leaf spreading and turning device includes a turning mechanism, and a spreading mechanism is provided above the turning mechanism;
[0006] The mixing mechanism includes an outer support, of which two are provided. A guide cylinder is fixedly installed at the top center of each outer support. A lifting rod is slidably connected through the inner wall of each guide cylinder. A top frame is fixedly installed at the bottom end of the two lifting rods. A servo motor is fixedly installed at the center of the top surface of the top frame. The output shaft of the servo motor extends downward through the top frame. A support rod is fixedly connected to the bottom end of the output shaft of the servo motor. The support rod extends radially as a whole. Flexible turning blades are glued and fixed to the outer bottom surface of the support rod.
[0007] As a further embodiment of this utility model: each of the guide cylinders has a fastening bolt threaded through and connected to its outer wall; the upper and lower ends of the lifting rod are provided with positioning holes; and the inside of each positioning hole is inserted into the end of the fastening bolt.
[0008] As a further embodiment of this utility model: a handle is fixedly connected to the lower end of the outer wall of each of the lifting rods, and a buffer ring is glued and fixed to the bottom surface of the top frame.
[0009] As a further embodiment of this utility model: the drying mechanism includes a shelf, and an inner support is welded and fixed around the bottom surface of the shelf. A ventilation opening is provided in the center of the surface of the shelf, and a bamboo tray is supported and placed in the center of the top surface of the shelf.
[0010] As a further embodiment of this utility model: limiting shafts are fixedly connected to both sides and the rear of the middle of the top surface of the shelf, the maximum distance between the two limiting shafts is consistent with the diameter of the tray, and the outer side wall of each limiting shaft abuts against the side of the tray.
[0011] As a further embodiment of this utility model: a limiting bolt is threaded through and connected to the front of the center of the top surface of the shelf, the top end of the limiting bolt extends to the top of the shelf, the maximum distance between the limiting bolt and the limiting shaft is consistent with the diameter of the spool, and the outer wall of the limiting bolt abuts against the spool.
[0012] As a further embodiment of this utility model: the top surface of the sluice plate is in contact with the buffer ring support, and an axial flow fan is provided on one side below the shelf. A support base is fixedly installed on the bottom surface of the axial flow fan, and the bottom surface of the support base is fixedly installed with one side of the outer bracket. The air outlet of the axial flow fan is set parallel to the ground.
[0013] The beneficial effects of this utility model are:
[0014] (1) This utility model supports the tea trays mounted on the shelf, and a liftable and movable top frame is set above the shelf. The support rod in the middle of the top frame is driven by a servo motor to rotate slowly and continuously. The bottom of the support rod is equipped with flexible turning leaves made of rubber. The flexible turning leaves can gently turn the tea on the tray at the same time. The contact between each flexible turning leaf and the tea not only avoids damage to the tea from rigid compression, but also saves manpower. There is no need for the operator to move around the tray and turn the fresh tea. Secondly, when the top frame falls, it covers the tray, thus preventing the tea from falling outside the device due to turning. In addition, the handle on the outside of the top frame can be used to gently move each flexible turning leaf. The flexible turning leaf contacts the top surface of the tea on the tray. When the flexible turning leaf rotates, the tea on the tray can be evenly spread.
[0015] (2) An axial flow fan is installed below the bamboo tray. When the axial flow fan is started, it can accelerate the air flow below the bamboo tray, promote the evaporation of tea moisture, and thus significantly improve the spreading efficiency. It is especially suitable for teas such as green tea that need to lose moisture quickly. The axial flow fan outputs airflow in the horizontal direction, thereby avoiding the airflow blowing directly on the tea leaves, thus avoiding large local airflow in the bamboo tray, and at the same time avoiding the airflow carrying dust to adhere to the surface of the tea leaves.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1-5 As shown, a fresh tea leaf spreading and turning device includes a turning mechanism 1, with a spreading mechanism 2 positioned above the turning mechanism 1. The turning mechanism 1 includes two outer supports 101. A guide cylinder 104 is fixedly installed at the top center of each outer support 101. A lifting rod 106 is slidably connected through the inner wall of each guide cylinder 104. A top frame 109 is fixedly installed at the bottom end of both lifting rods 106. A servo motor 111 is fixedly installed at the center of the top surface of the top frame 109. The output shaft of the servo motor 111 extends downward through the top frame 109. A support rod 112 is fixedly connected to the bottom end of the output shaft of the servo motor 111. The support rod 112 extends radially, and flexible turning blades 113 are glued and fixed to the outer bottom surface of the support rod 112. Figures 1-2 As shown, the servo motor 111 can be a MELSERVO-J4 series model. The ends of each flexible turning blade 113 are bent inward, so that when the flexible turning blade 113 rotates counterclockwise around the center of the support rod 112, it will gather and push the tea leaves above the bamboo tray 205 inward, preventing the tea leaves from being pushed out of the bamboo tray 205.
[0025] Each guide cylinder 104 has a through-hole and threaded fastening bolt 105 on its outer wall. The upper and lower ends of the lifting rod 106 are provided with positioning holes 108, and the interior of each positioning hole 108 is inserted into the end of the fastening bolt 105. Figures 2-3 As shown, when the upper and lower positioning holes 108 are respectively inserted with fastening bolts 105 for fixing, they can support and keep the top frame 109 in a raised or lowered state.
[0026] Each lifting rod 106 has a handle 107 fixedly connected to its lower outer wall, and a buffer ring 110 is glued and fixed to the bottom surface of the top frame 109. Figures 1-2 As shown, the buffer ring 110 is made of rubber to prevent the top frame 109 from directly impacting the tray 205 when it falls.
[0027] The drying mechanism 2 includes a shelf 201. Inner supports 202 are welded and fixed to all four sides of the bottom surface of the shelf 201. A ventilation opening is provided in the center of the surface of the shelf 201. A bamboo tray 205 is supported and placed in the center of the top surface of the shelf 201. Limiting shafts 203 are fixedly connected to both sides and the rear center of the top surface of the shelf 201. The maximum distance between the two limiting shafts 203 is the same as the diameter of the bamboo tray 205, and the outer side wall of each limiting shaft 203 abuts against the side of the bamboo tray 205. Figure 5 As shown, the tea leaves placed on the bamboo tray 205 can be naturally dried.
[0028] A limiting bolt 204 is threaded through and connected to the front of the center of the top surface of the shelf 201. The top of the limiting bolt 204 extends to the top of the shelf 201. The maximum distance between the limiting bolt 204 and the limiting shaft 203 is the same as the diameter of the ferrule 205, and the outer wall of the limiting bolt 204 abuts against the ferrule 205. Figure 5 As shown, after loosening the disassembly limit bolt 204, the bamboo tray 205 can slide out of the shelf 201, making it convenient to collect tea leaves.
[0029] The top surface of the tray 205 contacts the buffer ring 110, and an axial flow fan 103 is installed on one side below the shelf 201. A support base 102 is fixedly installed on the bottom surface of the axial flow fan 103. The bottom surface of the support base 102 is fixedly installed to one side of the outer bracket 101. The air outlet of the axial flow fan 103 is parallel to the ground. Figure 2 As shown, the axial flow fan 103 can be the FT35-11 model.
[0030] The working principle of this utility model:
[0031] When the device is in use, the bamboo tray 205 containing tea leaves is placed on the top center of the shelf 201 to dry, and the limiting bolt 204 is inserted and tightened in the threaded hole on the surface of the shelf 201. The limiting bolt 204, together with the three limiting shafts 203, clamps and positions the bamboo tray 205.
[0032] When it is necessary to spread the tea leaves out to cool, the fastening bolt 105 can be loosened to separate it from the lower positioning hole 108. Then, the operator holds the handle 107 and moves the top frame 109 to be placed above the bamboo tray 205, with the flexible turning leaf contacting the tea leaves placed in the bamboo tray 205. The servo motor 111 and the axial flow fan 103 are started. The servo motor 111 drives the flexible turning leaf 113 to rotate counterclockwise through the support rod 112. Thus, the flexible turning leaf 113 pushes the tea leaves above the bamboo tray 205 to move and stir. When the axial flow fan 103 is started, it maintains airflow below the bamboo tray 205, thereby promoting the evaporation of moisture from the tea leaves. After the tea leaves are stirred, the operator can use the handle 107 to slightly lift the top frame 109, so that the bottom surface of the flexible turning leaf 113 contacts the tea leaves. When the flexible turning leaf 113 rotates, it can push the tea leaves flat above the bamboo tray 205, preventing the tea leaves from piling up on the bamboo tray 205.
[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
