Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tea fruit peeling technology, specifically relating to a tea fruit peeling machine. Background Technology
[0002] The current method for separating tea bags from camellia seeds is as follows: the collected camellia fruits are spread out in a thin layer in time, dried in the sun for several days, and then the tea shells are removed by hand to obtain all the tea seeds. This method is time-consuming, labor-intensive, costly, and inefficient. The drying process of the tea fruits is lengthy and takes up a large area.
[0003] In the prior art, Chinese utility model application CN202223165633.7 discloses a camellia fruit peeling machine, including a peeling box and a rotating rod rotatably mounted inside the peeling box; a peeling mechanism is located at the upper and lower ends of the rotating rod; capable of continuously patting and squeezing the camellia fruit for rapid peeling. The peeling mechanism includes two electric telescopic cylinders, which are respectively screwed to the upper and lower ends of the rotating rod. This application utilizes the electric telescopic cylinders and concave plates on the rotating rod to rotate them, allowing the concave plates to roll and crush the camellia fruit inside the box, thus rapidly peeling the fruit. Furthermore, during the peeling process, the electric telescopic cylinders can be opened, causing the concave plates and pressure rollers to move up and down, squeezing the camellia fruit and rapidly breaking the outer shell, further improving peeling efficiency.
[0004] While the above-mentioned technical solution can crush and peel tea fruits, the tea fruits vary in size, and peeling them with pressure rollers may cause damage to larger tea seeds, leading to contamination of the equipment and affecting the peeling quality. Furthermore, it lacks a device for separating the fruit shells from the tea seeds, requiring the use of other screening equipment, which increases the processing steps, raises processing costs, and reduces the efficiency of shell separation.
[0005] To address these issues, we propose a tea fruit peeling machine. This machine uses flexible extrusion to break open the tea fruit, preventing damage to the seeds and ensuring quality during the peeling process. It also utilizes a screening device to vibrate and sift the broken tea fruit, separating the tea from the fruit. This integrated peeling and screening process reduces the cost of peeling and improves the efficiency of tea fruit peeling. Utility Model Content

[0035] The rubber sheet extrusion component 4 includes a double-layer plate 41 welded to the outside of the connecting shaft 25.

Multiple sets of fixing bolts 43 for fixing the peeling rubber sheet 42 are provided on the double-layer plate 41. The peeling rubber sheet 42 avoids rigid extrusion and damages the tea fruit seeds, thus improving the peeling quality.
[0036] The steel sieve mechanism 5 includes two sets of fixed rods 51 that are slidably installed in the mounting bucket 13. Two sets of arc beams 52 are fixedly connected to the two sets of fixed rods 51. Multiple sets of hemp steel 53 are welded above the two sets of arc beams 52.

[0037] Both ends of the two sets of fixed rods 51 are welded with limit rods 54. A shock-absorbing spring 55 is sleeved on the outside of the limit rod 54. A positioning rod 56 for limiting the shock-absorbing spring 55 is provided at the lower end of the shock-absorbing spring 55. The positioning rod 56 is welded to the top of the frame 1. The shock-absorbing spring 55 can easily buffer the steel screen mechanism 5, so that the tea fruit can be squeezed and shelled, avoiding rigid compression that damages the tea fruit seeds. A damper (not shown in the figure) is provided between the limit rod 54 and the positioning rod 56.
[0038] The drive unit includes a power motor 21 mounted on the top of the frame 1. The output shaft of the power motor 21 is connected to a drive wheel 22.

[0040] The first drag screen mechanism 8 includes two sets of first fixed blocks 81 fixedly connected to the bottom of the inner cavity of the frame 1. Each set of first fixed blocks 81 is rotatably connected to a first drag beam 82 on the opposite side. An I-beam connecting frame 83 is welded between the two sets of first drag beams 82. The I-beam connecting frame 83 improves the stability of the two sets of first drag beams 82 and facilitates the installation of the connecting rod 7. The structure is simple and the cost of the equipment is reduced.
[0041] The connecting rod 7 includes a first sleeve ring 71, with an inner bearing 72 rotatably connected to the crankshaft 35 inside the inner cavity of the first sleeve ring 71. A connecting sleeve rod 73 is welded to the outer side of the first sleeve ring 71, and a second sleeve ring 74 is welded to one end of the connecting sleeve rod 73. A fixing pin 75 is rotatably installed inside the second sleeve ring 74. The I-beam connecting frame 83 has multiple sets of rotating holes 84 for the fixing pin 75 to be rotatably installed. The multiple sets of rotating holes 84 facilitate the adjustment of the installation position of the fixing pin 75, thereby facilitating the adjustment of the tilt angle of the first drag screen mechanism 8, and further adjusting the tilt angle of the shell and seed screening frame 10, thus facilitating the adjustment of the shell and seed feeding speed.
[0042] The second drag screening mechanism 9 includes two sets of second fixing blocks 91 fixedly connected to the bottom of the inner cavity of the frame 1. The upper surfaces of the two sets of second fixing blocks 91 are welded with reinforcing rods 92. Both ends of the reinforcing rods 92 are rotatably connected to second drag beams 93. The reinforcing rods 92 can conveniently limit the position of the second drag beams 93, improve the stability of the second drag beams 93 supporting the shell and seed screening frame 10, and limit the range of shaking of the shell and seed screening frame 10.
[0043] The shell and seed screening frame 10 includes a seed collection frame 103. Multiple sets of third bearing seats 104 are fixedly connected to the lower surface of the seed collection frame 103. A support rod 105 is rotatably connected between every two sets of third bearing seats 104. The two sets of support rods 105 are rotatably connected to two sets of first trailing beams 82 and two sets of second trailing beams 93, respectively. Connecting plates 102 are welded to both sides of the seed collection frame 103. A screening frame 101 is welded between the two sets of connecting plates 102. The seed collection frame 103 facilitates the centralized collection of shelled seeds, thereby improving the collection efficiency.
[0044] The tensioning mechanism 6 includes an angle steel 61 detachably connected to the upper end of one side of the frame 1. Multiple sets of adjustment holes 62 are provided on one side of the angle steel 61. A locking bolt 64 is installed in one set of adjustment holes 62. A tensioning wheel 63 that rolls with the tensioning belt 32 is rotatably connected to the locking bolt 64. By installing the locking bolt 64 in the adjustment holes 62 at different positions, the tension of the tensioning belt 32 can be easily adjusted, thereby facilitating the installation of the first pulley 31 and the second pulley 33.
[0045] The tension spring mechanism 11 includes fixed seats 111 fixedly connected to both sides of the first drag beam 82. A buffer tension spring 112 is hung on the fixed seat 111. A pull rod 113 is hung on one end of the buffer tension spring 112. The pull rod 113 is detachably connected to the frame 1. The position of the first drag beam 82 mechanism is limited by the buffer tension spring 112, thereby reducing the swaying amplitude of the first drag screen mechanism 8 during the swinging process and improving the service life of the first drag screen mechanism 8.
[0046] A collection hopper 14 is welded to the top of the inner cavity of the frame 1. The collection hopper 14 is located directly above the screening frame 101. The feed end of the collection hopper 14 is connected to the discharge end of the installation hopper 13. Square holes are opened on both sides of the installation hopper 13 for sliding connection of the fixing rod 51 tube. The axis of the limiting rod 54 and the axis of the positioning rod 56 are both set on the same straight line. The collection hopper 14 facilitates the guidance of the broken tea fruit, so that the shells and seeds fall into the screening frame 101 for screening.
[0047] In use, the tea leaves to be shelled are placed into the installation hopper 13. The power motor 21 is started, which drives the drive wheel 22 to rotate the driven wheel 24 via the drive belt 23. The driven wheel 24 drives the connecting shaft 25 to rotate, and the connecting shaft 25 drives the shelling agitator between the double-layer plates 41 to squeeze the tea leaves. Under the flexibility of the shelling agitator and the action of the hemp steel 53, the tea leaves are broken. At the same time, the broken tea leaves fall through the gaps between the hemp steel 53, pass through the collection hopper 14 and fall into the screening frame 101. The connecting shaft 25 drives the first belt pulley 31 to tension the belt 32. The second pulley 33 is driven, which causes the crankshaft 35 to drive one end of the connecting rod 7 to make a circular motion. At the same time, the connecting rod 7, under the action of the fixed pin 75, drives the first drag screen mechanism 8 to swing at a certain angle, which causes the shell and seed screening frame 10 to vibrate. Since the shell and seed screening frame 10 is set at an inclination, the peeled tea fruit shells are separated from the seeds. The fruit shells are discharged and collected through the screening frame 101, and the seeds are collected through the seed collection frame 103. This facilitates the rapid separation of shells and seeds, improves the peeling efficiency of tea fruit, reduces the number of equipment used, and thus reduces the cost of the equipment.
