Description

Technical Field

[0001] This utility model relates to the field of Tibetan tea sieving technology, and in particular to a Tibetan tea air separation sieving device. Background Technology

[0002] In the processing of Tibetan tea, an air-separation sieving device is needed to sieve the tea to improve its taste.

[0003] For example, patent CN209318179U discloses a sieving and air-sorting fine processing device for red tea leaves, including a shell, with a feed inlet at the top of the shell, and a blower fixedly connected to the top of the shell and one side of the feed inlet. Two cylinders are symmetrically arranged on the outer wall of the side of the shell.

[0004] During the use of the aforementioned screening and air-separation refining device, firstly, since the tea leaves are all fed into the inlet, due to the limited location of the inlet, the tea leaves tend to accumulate in the receiving area of ​​the screen after being fed in. Even with the movement of the screen, it is difficult to spread out the accumulated tea leaves, thus increasing the difficulty of screening; secondly, the area guided by the air hood is limited and cannot cover the entire area of ​​the screen, which also brings difficulties to the air-separation screening of tea leaves. Therefore, this application provides a Tibetan tea air-separation screening device to meet the needs. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a Tibetan tea air separation and sieving device to address two issues: First, since tea leaves are fed into the inlet, due to the limited location of the inlet, the tea leaves tend to accumulate in the receiving area of ​​the screen after being fed in. Even with the movement of the screen, it is difficult to spread out the accumulated tea leaves, thus increasing the difficulty of sieving. Second, the area guided by the air hood is limited and cannot cover the entire area of ​​the screen, which also brings difficulties to the air separation and sieving of tea leaves.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A Tibetan tea air-separation and sieving device includes a main body, a front door installed at the front end of the main body, and a feed inlet fixed on one side of the upper part of the main body. A sieving mechanism is installed in the middle section of the interior of the main body, and an auxiliary sieving mechanism is installed both inside and outside the main body. Guide frames are fixed on both sides inside the main body, and a collection mechanism is installed at the bottom inside the main body. The auxiliary sieving mechanism includes a leveling component, which is installed on the upper part of the interior of the main body. Side-mounted slots are fixed on both sides of the upper part of the interior of the main body, and a movable air-separation component is installed on the inner side of the two side-mounted slots and on the upper part of the main body.

[0008] Optionally, the leveling assembly includes a second motor, which is mounted on one side of the main body. A first transmission screw is mounted on the output end of the second motor, and a first screw sleeve is screwed around one side of the first transmission screw. A lower mounting frame is fixed below the first screw sleeve, and a rotating rod is mounted in the middle of the lower mounting frame. A third motor is mounted on one side of the rotating rod, and leveling plates are fixed around the periphery of the rotating rod. A guide rod is fixed on the other side of the main body.

[0009] Optionally, the guide rod and the movable slot opened on one side of the lower frame are connected by a movable guide connection.

[0010] Optionally, the mobile air separator assembly includes a filter mounting frame, which is mounted on the upper side of the main body. A fan is installed inside the filter mounting frame. A connecting pipe is connected to the upper side of the main body, and a telescopic flexible air duct is connected to one end of the connecting pipe. An air separator head is installed at the end of the telescopic flexible air duct, and connecting frames are fixed on both sides of the air separator head. A second transmission screw is installed inside one of the side mounting frames, and a fourth motor is connected to one end of the second transmission screw. A second screw sleeve is screwed around one side of the second transmission screw.

[0011] Optionally, the connecting frame fixed on one side of the air separator head is fixedly connected to the second lead screw sleeve, and the connecting frame fixed on the other side of the air separator head is connected to another side mounting slot frame in a movable guide connection.

[0012] Optionally, the screening mechanism includes an assembly frame, which is disposed inside the main body. The assembly frame has first sliders fixed on both sides inside, a screening frame slides on the contact surface of the first sliders, and magnetic blocks are fixed around the front end of the screening frame. Sliding frames are fixed at each corner of both sides of the assembly frame, and reset spring frames are fixed on both sides of the assembly frame. Side guide grooves are opened on both sides of the main body. A first motor is installed on one side inside the main body, and an eccentric wheel is installed at the output end of the first motor.

[0013] Optionally, the side guide groove and the corresponding sliding frame are connected by a sliding guide connection.

[0014] Optionally, the magnetic block at the front end of the filter frame is magnetically fixed to the corresponding position of the assembly frame.

[0015] Optionally, the collection mechanism includes a fixing frame, which is symmetrically fixed to the inner bottom of the main body. The inner sides of the two fixing frames are provided with guide grooves, and the inner sides of the guide grooves are provided with guide blocks. The inner sides of the guide blocks are fixed with collection chambers.

[0016] Optionally, the size of the opening above the collection chamber is larger than the size of the guide opening formed at the ends of the two guide frames.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up an auxiliary screening mechanism, the tea leaves may accumulate in the screening area when they are put into the screening rack. At this time, the operator can start the second motor to rotate the first transmission screw. The first screw sleeve, which interacts with the screw, will move laterally with the lower frame and guide rod. During this process, the operator can start the third motor to rotate the rotating rod and the surrounding spreading plates. With the above displacement structure, the accumulated tea leaves can be assisted in spreading out, avoiding difficulties in screening. Then, the operator can start the blower. Under the guidance of the connecting pipe and the telescopic flexible air pipe, the air force can come out from the air separator head, which can achieve a relatively efficient air separation screening effect with the screening mechanism. In order to ensure the uniformity of the tea leaves above the screening rack by air separation, the operator can start the fourth motor to rotate the second transmission screw. The second screw sleeve, which interacts with the screw, will move laterally with the connecting frame and the air separator head in operation, guided by one of the side mounting slots, thus ensuring the uniformity and comprehensiveness of air separation screening.

[0019] By setting up a screening mechanism, the staff put the Tibetan tea to be processed into the screening frame in the main body through the feed inlet. At this time, the staff can start the first motor to make the eccentric wheel rotate. Under the special structure of the eccentric wheel, the assembly frame with reset spring frame, sliding frame and side guide groove is intermittently provided with good vibration guidance. Since the screening frame is located inside the assembly frame, the screening of Tibetan tea material is guaranteed. After screening, the staff can take out the qualified Tibetan tea by using the detachable assembly frame and the screening frame.

[0020] By setting up a collection mechanism, the impurities screened in the filter rack will fall into the collection bin as guided by the guide frame. Personnel can then use the guide groove and guide block to remove the collection bin for appropriate processing. Attached Figure Description

[0035] like Figures 1 to 3As shown, an embodiment of this utility model provides a Tibetan tea air-sorting and sieving device, including a main body 1. A front door 2 is installed at the front end of the main body 1, and a feed inlet 3 is fixedly provided on one side of the upper part of the main body 1. A sieving mechanism 4 is installed in the middle section of the interior of the main body 1, and an auxiliary sieving mechanism 5 is installed both inside and outside the main body 1. Guide frames 6 are fixedly provided on both sides inside the main body 1, and a collection mechanism 7 is installed at the bottom inside the main body 1. The sieving mechanism 4 includes an assembly frame 41, which is located inside the main body 1. First sliders 42 are fixedly provided on both sides inside the assembly frame 41. A sieve frame 43 is slidably provided on the contact surface of the first sliders 42, and magnetic blocks 44 are fixedly provided around the front end of the sieve frame 43. The magnetic blocks 44 at the front end of the sieve frame 43 are magnetically fixedly connected to the corresponding positions of the assembly frame 41. Sliding frames 45 are fixedly provided at each corner of both sides of the assembly frame 41, and the sides of the assembly frame 41... Two reset spring frames 47 are fixed on both sides, and side guide grooves 46 are opened on both sides of the main body 1. A first motor 48 is installed on one side inside the main body 1, and an eccentric wheel 49 is installed at the output end of the first motor 48. The side guide grooves 46 and the corresponding sliding frames 45 are connected by a sliding guide. The workers put the Tibetan tea to be processed into the sieve frame 43 in the main body 1 through the feed port 3. At this time, the workers can start the first motor 48 to make the eccentric wheel 49 rotate. Under the special structure of the eccentric wheel 49, it can intermittently provide good vibration guidance to the assembly frame 41, which is equipped with reset spring frames 47, sliding frames 45 and side guide grooves 46 on all sides. Since the sieve frame 43 is located inside the assembly frame 41, the sieve frame 43 can screen the Tibetan tea material. After the screening is completed, the workers can take it out by using the detachability of the assembly frame 41 and the sieve frame 43 to collect qualified Tibetan tea.

[0036] like Figures 1 to 5As shown, the auxiliary screening mechanism 5 includes a leveling component 51, which is installed inside the upper part of the main body 1. The leveling component 51 includes a second motor 511, which is installed on one side of the main body 1. A first transmission screw 512 is installed at the output end of the second motor 511, and a first screw sleeve 513 is screwed around one side of the first transmission screw 512. A lower mounting frame 514 is fixed below the first screw sleeve 513, and a rotating rod 515 is installed in the middle of the lower mounting frame 514. A third motor 516 is installed on one side of the rotating rod 515, and a leveling plate 517 is fixed around the rotating rod 515. A guide rod 518 is fixed on the other side of the main body 1, and the guide rod 518 and the lower mounting frame 514 are connected by a... The movable slots are connected by a movable guide. Side-mounted slot frames 52 are fixedly installed on both sides of the upper part of the main body 1. A movable air separator assembly 53 is jointly installed on the inner sides of the two side-mounted slot frames 52 and on the inner and outer sides of the upper part of the main body 1. The movable air separator assembly 53 includes a filter mounting frame 531, which is installed on the upper side of the main body 1. A fan 532 is installed inside the filter mounting frame 531. A connecting pipe 533 is connected to the upper side of the inside of the main body 1, and a telescopic flexible air duct 534 is connected to one end of the connecting pipe 533. An air separator head 535 is installed at the end of the telescopic flexible air duct 534, and connecting frames 536 are fixedly installed on both sides of the air separator head 535. A second transmission screw 537 is installed inside one of the side-mounted slot frames 52. A fourth motor 538 is connected to one end of the second transmission screw 537. A second screw sleeve 539 is screwed around one side of the second transmission screw 537. A connecting frame 536 fixed on one side of the air separator head 535 is fixedly connected to the second screw sleeve 539. A connecting frame 536 fixed on the other side of the air separator head 535 is connected to another side mounting frame 52. When the tea leaves are put into the sieve frame 43, they may accumulate in the input area. At this time, the operator can start the second motor 511 to rotate the first transmission screw 512. At this time, the first screw sleeve 513, which interacts with the screw, will carry the lower mounting frame 514 and guide the guide rod 518 to move laterally. During this process, the operator can start the third motor 516 to rotate the rod 515 and its surrounding parts. The rotating flat plate 517, in conjunction with the aforementioned displacement structure, can assist in leveling the tea material in the pile, avoiding difficulties in screening the screening mechanism 4. Then, the operator can start the blower 532. Guided by the connecting pipe 533 and the telescopic flexible air pipe 534, the air force can come out from the air separator head 535, achieving a relatively efficient air separation screening effect in conjunction with the screening mechanism 4. In order to ensure the uniformity of the tea material above the screening frame 43 by air separation, the fourth motor 538 is started to rotate the second transmission screw 537. The second screw sleeve 539, which interacts with the screw, carries the connecting frame 536 and the air separator head 535 in operation, and moves laterally in conjunction with the guide of one of the side mounting slot frames 52, thereby ensuring the uniformity and comprehensiveness of air separation screening.

[0037] The collection mechanism 7 includes a fixed frame 71, which is symmetrically fixed to the bottom of the main body 1. The inner sides of the two fixed frames 71 are provided with guide grooves 72, and the inner sides of the guide grooves 72 are provided with guide blocks 73. The inner sides of the guide blocks 73 are fixed with collection chambers 74. The size of the opening above the collection chamber 74 is larger than the size of the guide opening formed at the ends of the two guide frames 6. The impurities screened in the filter frame 43 will fall into the collection chamber 74 as guided by the guide frame 6. Personnel can then use the guide grooves 72 and guide blocks 73 to remove the collection chamber 74 for appropriate processing.

[0038] The working principle of the technical solution provided by this utility model is as follows:

[0039] Workers first feed the Tibetan tea to be processed into the sieve frame 43 in the main body 1 through the feed inlet 3. At this time, the first motor 48 can be started to rotate the eccentric wheel 49. Due to the special structure of the eccentric wheel 49, it can intermittently provide good vibration guidance to the assembly frame 41, which is equipped with a reset spring frame 47, a sliding frame 45, and a side guide groove 46. Since the sieve frame 43 is located inside the assembly frame 41, this ensures the sieve frame 43 can screen the Tibetan tea material. After screening, the assembly frame 41 and the sieve frame 43 can be removed to collect the qualified Tibetan tea. Secondly, when Tibetan tea material is fed into the sieve frame 43, it may cause accumulation in the feeding area. At this time, the second motor 511 can be started to rotate the first transmission screw 512. At this time, the first screw sleeve 513, which interacts with the screw, will carry the lower frame 514 and guide rod 518 to move laterally. During this process, the third motor 516 can be started to rotate the rotating rod 515 and its surrounding parts. The rotating flat plate 517, in conjunction with the aforementioned displacement structure, assists in leveling the tea material in the pile, avoiding difficulties in screening the sieving mechanism 4. Then, the operator can start the blower 532. Guided by the connecting pipe 533 and the telescopic flexible air duct 534, airflow comes out from the air separator head 535, achieving a relatively efficient air separation effect in conjunction with the screening mechanism 4. To ensure the uniformity of the tea material above the screening frame 43, the fourth motor 538 is started to rotate the second transmission screw 537. This causes the second screw sleeve 539, acting on the screw, to move laterally along with the connecting frame 536 and the air separator head 535, guided by one of the side mounting frames 52. This ensures the uniformity and comprehensiveness of the air separation. Finally, the impurities screened in the screening frame 43 will fall into the collection bin 74 guided by the guide frame 6. The operator can then use the guide groove 72 and guide block 73 to remove the collection bin 74 for further processing.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
