DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] like Figure 1-Figure 6 As shown, this embodiment provides a tea cooling and air separation machine, including a feeding part 10 and an air separation part 20.

[0027] Specifically, Figure 1 , Figure 4 , Figure 6 As shown, the feed section 10 includes a group of brackets 11, a feed box 12, a material guide mesh frame 13, a material discharge plate 14, and a conveyor belt 15. A group of brackets 11 are arranged at intervals along the conveying direction of the conveyor belt 15, and a group of brackets 11 are inverted U-shaped. The feed box 12 is arranged between a group of brackets 11 and uses the top of a group of brackets 11 as support. The material guide mesh frame 13 is arranged in an array along the bottom of the feed box 12, and its array direction is parallel to the conveying direction of the conveyor belt. The upper and lower ends of the material guide mesh frame 13 have openings. The material discharge plate 14 is arranged at the bottom of the material guide mesh frame 13, and a plurality of strip grooves are arranged on the material discharge plate 14, so that the strip grooves correspond to the bottom openings of the material guide mesh frame 13 one by one, which is used to control the flow rate of tea leaves in the material guide mesh frame 13.

[0028] The wind selection section 20 is arranged at the end of the conveying direction of the conveyor belt 15. The wind selection section 20 includes a dustproof mesh cover 21, multiple partitions 22, a collection box 23, a first cooling fan 24, and a closed net 25. The end of the conveyor belt 15 extends into one end of the dustproof mesh cover 21. Multiple partitions 22 are arranged parallel to and spaced apart from the dustproof mesh cover 21. The arrangement direction is consistent with the conveying direction of the conveyor belt 15 and is located below the conveying direction of the conveyor belt 15. The projection of the end of the conveyor belt 15 at the two partitions 22 closest to the end of the conveyor belt 15 falls between the two partitions 22, thereby preventing the tea leaves at the end of the conveyor belt 15 from falling out of the partitions 22 and causing waste. The collection box 23 is correspondingly arranged below the adjacent partitions 22, and is used to collect tea leaves or impurities in the tea leaves. The collection box 23 can be pulled out along the width direction perpendicular to the dustproof mesh cover 21 to facilitate the removal of the collected tea leaves or impurities, and to facilitate the cleaning of the collection box 23. The first cooling fan 24 is disposed at one end of the dustproof mesh cover 21, and the closed net 25 is disposed at the other end of the dustproof mesh cover 21 to prevent impurities or dust from being scattered outside the dustproof mesh cover 21 under the action of the first cooling fan 24 and affecting the operating environment. The first cooling fan 24 is correspondingly located below the end of the conveying direction of the conveyor belt 15, and an air inlet duct is disposed between the first cooling fan 24 and the dustproof mesh cover 21, so that the cold air generated by the first cooling fan 24 directly enters the dustproof mesh cover 21.

[0029] Specific usage process:

[0030] The tea leaves after high temperature stir-frying are poured into the feed box 12, and the tea leaves in the feed box 12 automatically and dispersedly fall into the guide mesh frame 13 along the bottom of the feed box 12, so that the tea leaves after high temperature stir-frying are spread out, so that the tea leaves can be timely cooled and avoid being accumulated in the feed box 12, thereby improving the quality of the tea leaves. The discharge plate 14 is reciprocated along the conveying direction of the conveyor belt 15, so that the tea leaves in the guide frame 13 are laid on the conveyor belt 15 in sequence and uniformly, and the conveyor belt 15 then conveys the tea leaves to the dustproof mesh cover 21, so that the tea leaves fall freely along the end of the conveyor belt 15, and the first cooling fan 24 is started to blow cold air into the dustproof mesh cover 21, and the falling tea leaves are cooled again, and the tea leaves are screened at the same time.

[0031] Specifically, Figure 1 , Figure 4 As shown, in order to accelerate the cooling of the tea leaves in the material guiding mesh frame 13, a second cooling fan 16 is provided on one side between a group of brackets 11, so that the wind blown by the second cooling fan 16 is perpendicular to the array direction of the material guiding mesh frames 13, thereby taking away the heat between adjacent material guiding mesh frames 13 and increasing the cooling speed of the tea leaves.

[0032] In order to ensure that the feed box 12 has better stability at the moment when the tea leaves are poured in, and to prevent the feed box 12 from being displaced and detached from the support of the group of brackets 11 when the tea leaves are poured in, U-shaped seats 17 are hinged on both sides of the top of the group of brackets 11. When in use, the feed box 12 is first placed on the group of brackets 11, and then the U-shaped seat 17 is rotated to the opposite side of the group of brackets 11, so that the two arms of the U-shaped seat 17 limit the two side surfaces of the feed box 12 respectively, and the operation is convenient.

[0033] Specifically, Figure 2 As shown, a plurality of dividing rods 121 are arranged in an array at the bottom of the feed box 12, and the top of the guide mesh frame 13 is arranged between adjacent dividing rods 121 to prevent tea leaves from leaking out from between adjacent guide mesh frames 13, and at the same time, the distance between two adjacent guide mesh frames 13 is increased to better dissipate heat of the tea leaves in the guide mesh frames 13. To prevent tea leaves from accumulating on the top surface of the dividing rods 121, the top of the cross section of the dividing rods 121 is arranged to be a triangular structure.

[0034] Specifically, Figure 2-Figure 3As shown, when the material guiding mesh frame 13 needs to be cleaned or replaced, in order to facilitate disassembly, ear plates 131 are respectively extended upward at both ends of the top of the material guiding mesh frame 13, and a rectangular hole 132 is provided on the ear plate 131. A connecting pin 133 is passed through the rectangular hole 132. The cross-section of the connecting pin 133 is adapted to the cross-section of the rectangular hole 132 to prevent the material guiding mesh frame 13 from swinging and causing the tea leaves to leak out from the connection between the top of the material guiding mesh frame 13 and the bottom of the feed box 12, so that one end of the connecting pin 133 passes through the rectangular hole 132 and is plugged into the feed box 12.

[0035] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
