Description

Technical Field

[0001] The present invention relates to the technical field of tea leaf picking devices, and particularly to a tea leaf picking and grading device.

Background Art

[0002] Tea is a widely consumed beverage worldwide, and grading, as an important part of tea production, has a decisive impact on the quality and taste of tea leaves.

[0003] Fresh tea leaves are graded according to the number of fresh leaves, size, number of leaves on the new shoots, and degree of opening, and different tea leaves are made from fresh tea leaves of different grades. Currently, when tea pickers pick tea leaves, they manually select fresh tea leaves by grade based on experience. However, since the picking cycle of tea leaves is short, the picking and sorting by tea pickers can significantly reduce the efficiency of picking and grading fresh tea leaves and may reduce the economic benefits of tea trees.

[0004] Therefore, those skilled in the art are working on the development of a tea leaf picking and grading device that can improve the grading efficiency of tea leaves by automatically sorting tea leaves according to their grades when picking tea leaves.

The long belt conveyor assembly 108 is installed at an angle, and a gap is provided between two adjacent long belt conveyor assemblies 108 to accommodate and hold the one-bud, three-leaf tea leaves. Since the long belt conveyor assembly 108 can only hold the one-bud, three-leaf tea leaves (or more), it separates the one-bud, three-leaf tea leaves (or more) from the picked tea leaves. The long belt conveyor assembly 108 is mounted inside the picking frame 101, and a one-bud, three-leaf conveyor assembly is provided at the output end of the long belt conveyor assembly 108.

[0036] In this embodiment, the single-core, three-lobe conveyor assembly comprises a single-core, three-lobe first conveyor belt assembly 2301, with both ends of the single-core, three-lobe first conveyor belt assembly 2301 stretched over a first pulley 2302 and a second pulley 2303, and a single-core, three-lobe first conveyor motor 2304 rotationally drives the single-core, three-lobe first conveyor belt assembly 2301. A single-core, three-lobe second conveyor belt assembly 2305 is provided at the output end of the single-core, three-lobe first conveyor belt assembly 2301, with both ends of the single-core, three-lobe second conveyor belt assembly 2305 stretched over a third pulley 2306 and a fourth pulley 2307, and a single-core, three-lobe second conveyor motor 2308 rotationally drives the single-core, three-lobe second conveyor belt assembly 2305 to transport the single-core, three-lobe conveyor belt to a designated position. In another embodiment, a single-core, three-leaf blowing fan is attached to the end of a single-core, three-leaf second conveyor belt assembly 2305, and the single-core, three-leaf blowing fan blows the single-core, three-leaf raw tea leaves being conveyed by the single-core, three-leaf second conveyor belt assembly 2305 into a collection bag.

[0037] In several embodiments, the picking frame 101 is mounted inside the first sorting frame 2001 and the second sorting frame 2002, with the first pulley motor 105 mounted on the side wall of the first sorting frame 2001. The output terminal of the first pulley motor 105 is connected to the first pulley gearbox 106, and the output terminal of the first pulley gearbox 106 is connected to the short belt conveyor assembly 107. The first pulley motor 105 rotates the gears inside the first pulley gearbox 106, which in turn rotates the short belt conveyor assembly 107, transporting the picked tea leaves to the rear, thereby facilitating subsequent classification and sorting.

[0038] The single-core, single-leaf sorting assembly is located beneath the short belt conveyor assembly 107 and includes an identification assembly 2209 for identifying single cores and single leaves, and a light source 2210 for illuminating the fresh leaves 2008. Multiple identification assemblies 2209 and light sources 2210 are uniformly arranged beneath the short belt conveyor assembly 107, and in this embodiment, 24 sets of identification assemblies 2209 and light sources 2210 cooperating with the identification assemblies 2209 are provided. The identification assemblies 2209 can use high-speed cameras, and the light sources 2210 can use LED light sources.

[0039] A control device is electrically connected to the identification assembly 2209. Multiple blowing pipes 2007 for blowing in single-core, single-leaf plants are provided on the underside of the tip of the short belt conveyor assembly 107. A junction plate connecting pipe 2006 and a junction plate 2005 are sequentially connected to the blowing pipes 2007. A solenoid valve 2004 is attached to the blowing pipe 2007, and the solenoid valve 2004 is electrically connected to the control device. When sorting single-core, single-leaf plants, a light source 2210 illuminates the fresh leaves 2008. When the identification assembly 2209 identifies the fresh leaves 2008 and determines that they are single-core, single-leaf plants, the short belt conveyor assembly 107 transports the single-core, single-leaf plants to a designated position. After this, the control device controls the opening of the solenoid valve 2004, and compressed air is blown out from the blowing pipes 2007 into the single-core, single-leaf plant conveyor assembly.

[0040] As shown in Figures 1 to 8, in another embodiment, a single-core, single-leaf first conveyor belt assembly 2101 is further mounted within the first sorting frame 2001 and the second sorting frame 2002, with both ends of the single-core, single-leaf first conveyor belt assembly 2101 stretched over the ninth pulley 2102 and the tenth pulley 2103, respectively. The single-core, single-leaf first conveyor belt assembly 2101 is used to receive single-core, single-leaf belts blown in by the blowing pipe 2007, and a single-core, single-leaf first pulley motor 2104 rotates the single-core, single-leaf first conveyor belt assembly 2101.

In another embodiment, a single-core, single-leaf blowing fan is attached to the tip of the second single-core, single-leaf conveyor belt assembly 2105, and the single-core, single-leaf blowing fan blows the single-core, single-leaf conveyed by the second single-core, single-leaf conveyor belt assembly 2105 into a collection bag.

[0041] In this embodiment, the leaf sorting assembly includes a first leaf sorting conveyor belt assembly 2201, which is installed at an incline, with both ends of the first leaf sorting conveyor belt assembly 2201 stretched over a fifth pulley 2202 and a sixth pulley 2203, a first leaf sorting motor 2204 rotationally drives the first leaf sorting conveyor belt assembly 2201, and a second leaf sorting conveyor belt assembly 2205 is provided below the tip of the first leaf sorting conveyor belt assembly 2201. A second conveyor belt assembly 2205 for separating leaf fragments is installed at an incline, with both ends of the second conveyor belt assembly 2205 being stretched over a seventh pulley 2206 and an eighth pulley 2207. A second leaf separation motor rotates the second conveyor belt assembly 2205, and an axial flow fan 2208 for sucking up leaf fragments is provided below the tip of the second conveyor belt assembly 2205. When the single-core, two-leaf and leaf fragments are conveyed to the tip by the second conveyor belt assembly 2205 and fall, the leaf fragments are light and are sucked up by the axial flow fan 2208 and conveyed to the designated position, thus separating the leaf fragments from the single-core, two-leaf.

[0042] The single-core, two-leaf sorting assembly is located at the output end of the second conveyor belt assembly 2205 for leaf separation and includes a single-core, two-leaf collection tank for collecting and storing the single-core, two-leaf pieces.

[0043] In this embodiment, the first conveyor belt assembly 2201 for leaf separation and the second conveyor belt assembly 2205 for leaf separation are mounted inside the second sorting frame 2002, the first sorting frame 2001 and the second sorting frame 2002 are fixedly connected, and a cover plate 2003 is further fixedly connected to the end of the second sorting frame 2002.

[0044] The first sorting frame 2001 and the second sorting frame 2002 are attached to the frame 4, and the air compression assembly 6 and battery assembly 5 are further attached to both sides of the upper end of the frame 4, and the running device 3 is further attached to the bottom of the frame 4. In this embodiment, the running device 3 can use a crawler-type running assembly, and a running motor is attached to the frame 4, and the output end of the running motor is connected to the running assembly via a chain, making it easy for the running assembly to move between tea rows. The frame 4 can use multiple aluminum profiles, and the frame 4 is connected to the running device 3 via connecting members. The battery assembly 5 can use a lithium battery assembly and is attached to the frame 4. The air compression assembly 6 can use a small air compressor and is electrically connected to the control device. The battery assembly 5 and the air compression assembly 6 are located on both sides of the frame 4, and the air discharge end of the air compression assembly 6 is in communication with the junction plate 2005 via an air pipe.

[0045] The operating principle of this invention is as follows:

[0046] When fresh leaves 2008 enter the single passage of the harvesting device 1, they are first held in the passage formed by the short belt conveyor assembly 107 below the harvesting device 1, and then harvested by the reciprocating cutting blade 102. After a predetermined time, the short fresh leaves 2008 fall directly away from the passage formed by the short belt conveyor assembly 107, while the long fresh leaves 2008 are subsequently held in the passage formed by the long belt conveyor assembly 108 above the harvesting device 1, transported to a higher position, and then fall away from the passage formed by the long belt conveyor assembly 108.

[0047] The fresh leaves picked by the picking device 1 are classified into two types. The first type of fresh leaves consists of one bud and three leaves (or more than one bud and three leaves), and after being picked, they are held in a conveying passage before being held in a passage formed by the long belt conveyor assembly 108. The second type of fresh leaves consists of one bud and one leaf, one bud and two leaves, and cut leaves, and after being picked, they are held in a passage formed by the short belt conveyor assembly 107. The fresh leaves 2008 picked by the front picking device 1 enter the rear sorting device 2 at predetermined intervals.

[0048] The first type of fresh leaves (one bud and three leaves or more) are held in a passage formed by the long belt conveyor assembly 108 above the harvesting device 1, then fall onto the first conveyor belt assembly 2301 for one bud and three leaves, are transported for a predetermined time, then fall onto the second conveyor belt assembly 2305 for one bud and three leaves, and finally are transported to the front of the device.

[0049] The second type of fresh leaf is held in a passage formed by the short belt conveyor assembly 107 below the picking device 1, and the moment it is released from the short belt conveyor assembly 107, the identification assembly 2209 photographs and identifies the fresh leaf 2008 in the air.

[0050] When the fallen fresh leaf 2008 is identified as a single core and single leaf by the identification assembly 2209, the solenoid valve 2004 opens, creating a passage between the confluence plate connecting pipe 2006 and the confluence plate 2005, and high-pressure gas is ejected from the tip of the blowing pipe 2007, blowing the fresh leaf 2008 onto the single core and single leaf first conveyor belt assembly 2101, where it is transported for a predetermined time before falling onto the single core and single leaf second conveyor belt assembly 2105, and finally being transported to the front of the device.

[0051] When the fallen fresh leaves 2008 are identified as one-core, two-leaf and broken leaves by the identification assembly 2209, the fresh leaves 2008 naturally fall onto the first conveyor belt assembly 2201 for broken leaf sorting, are transported for a predetermined time, then fall onto the second conveyor belt assembly 2205 for broken leaf sorting, and are then transported to a higher position by the second conveyor belt assembly 2205 for broken leaf sorting and fall. As the fresh leaves 2008 naturally fall, the broken leaves, being lighter, are sucked out of the device by the airflow of the axial fan 2208, and the one-core, two-leaf leaves fall into a one-core, two-leaf collection tank (not shown).
