[0001] The utility model relates to the technical field of tea processing, in particular to an automatic detection and impurity removal device for the tea withering link. Background Technique
[0002] With the continuous improvement of the national economy and living standards, the market demand for high-end and high-quality tea is also increasing. However, during the tea picking process, impurities such as branches (leaves), old leaves, sand, and small insects are often mixed in. These impurities will affect the quality of the finished tea, so these impurities need to be removed in the tea processing link.
[0003] In the traditional tea production process, impurities are usually manually picked out. Not only is the impurity removal effect poor, but also the efficiency is low and the manual labor is large. Some subsequent mechanical tea impurity removal devices only filter and remove impurities by installing a filter screen. Although it replaces manual labor, its filtering and impurity removal effect is not ideal, and it is difficult to remove impurities such as branches (leaves) and old leaves that are similar in shape to tea leaves. In order to improve the efficiency and automation of tea impurity removal, air separation and color sorting are applied to tea impurity removal. However, air separation and color sorting require the configuration of special air separation and color sorting equipment and the setting of special impurity removal links, which not only increases the cost of tea processing, but also during the air separation and color sorting process, the tea will be impacted and collided, and is easily damaged, affecting the tea quality.
[0004] In addition, some impurities such as small insects are likely to adhere to the tea during the later heat processing process, resulting in being unable to be removed later. Content of the Utility Model

Specific implementation manner
[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0024] Embodiment 1
[0025] As Figure 1-6 shown, this embodiment discloses an automatic detection and impurity removal device for the tea withering process, including a support plate 50, a sliding bracket 10, a cross beam 20, an identification component 30 and an impurity removal component 40. The support plate 50, the sliding bracket 10 and the cross beam 20 are used to install the identification component 30 and the impurity removal component 40. The identification component 30 is used to capture the image of the fresh tea leaves in the withering trough, identify the impurities and transmit the instructions to the impurity removal component 40. The impurity removal component 40 moves to the position where the impurities are located according to the instructions and sucks the impurities.
[0026] Specifically, the support plate 50 is arranged on the outer side wall of the tea withering machine, and its length direction is consistent with the length direction of the tea withering machine. A slide rail 51 is arranged on the upper surface of the support plate 50 along its length direction, and the sliding bracket 10 is slidably arranged on the slide rail 51 through a slider. A rack 52 is arranged on the lower surface of the support plate 50 along its length direction. The bottom of the outer side of the sliding bracket 10 extends downward to the lower part of the support plate 50 to form a mounting plate 11. A driving motor 12 is fixedly arranged on the outer side surface of the mounting plate 11. The output shaft of the driving motor 12 penetrates through the mounting plate 11 inward and is provided with a gear 13 at the inner end. The gear 13 meshes with the rack 52. By driving the gear 13 to rotate by the driving motor 12, under the meshing action of the gear 13 and the rack 52, the sliding bracket 10 is pushed to slide along the slide rail 51, so as to realize the movement of the identification component 30 and the impurity removal component 40 in the length direction of the tea withering machine, and thus identify and remove the impurities in the withering trough.
[0027] A cross beam 20 that extends above the withering trough of the tea withering machine is provided on the sliding support 10. In the working state, the length direction of the cross beam 20 is perpendicular to the length direction of the tea withering machine. The recognition component 30 and the impurity removal component 40 are installed on the cross beam 20. Specifically, the recognition component 30 includes a mounting bracket 31 provided in the middle of the cross beam 20. A recognition camera 32 is arranged obliquely downward on the mounting bracket 31. The fresh tea leaves image in the withering trough is taken by the recognition camera 32, and then the image data is transmitted to an analysis module (not shown in the figure) for analysis to identify the impurity information and the impurity position, and then it is converted into a control instruction through a control module (not shown in the figure) and transmitted to the impurity removal component 40 for precise impurity removal.
[0028] To prevent tea hairs and dust from adhering to the lens of the recognition camera 32 when the tea is being laid out, which may affect the clarity of the image taken by the recognition camera 32, a dust-proof cover 33 with an opening at the lower side is covered outside the recognition camera 32 to protect the recognition camera 32. The dust-proof cover 33 includes a cover body 34. A hinge shaft 35 is rotatably arranged at the lower edge of the top side plate of the cover body 34. A cover door panel 36 that is hermetically matched with the opening at the lower side of the dust-proof cover 33 is arranged on the hinge shaft 35. A rotating motor 37 is arranged on the side of the dust-proof cover 33. A first bevel gear 38 is arranged on the output shaft of the rotating motor 37. A second bevel gear 39 is arranged at one end of the hinge shaft 35 close to the rotating motor 37. The first bevel gear 38 meshes with the second bevel gear 39. By driving the first bevel gear 38 to rotate by the rotating motor 37, the second bevel gear 39 is driven to rotate, so that the cover door panel 36 can be driven to open or close. That is, when the recognition camera 32 is not in use, the cover door panel 36 is in the closed state to protect the recognition camera 32; when the recognition camera 32 needs to be used, the rotating motor 37 drives the cover door panel 36 to open, and when the cover door panel 36 opens, it rotates to the upper side of the cover body 34 and will not block the lens of the recognition camera 32.
[0029] The impurity removal component 40 includes a dust suction fan 41 and a first pneumatic slide table 42. The dust suction fan 41 is fixedly installed on one side of the cross beam 20 close to the sliding support 10, which can make the center of gravity of the whole mechanism tend to one side of the sliding support 10 and improve the movement stability of the whole mechanism. The length direction of the first pneumatic slide table 42 is consistent with the length direction of the cross beam 20 and is arranged at the bottom of the cross beam 20. An L-shaped sliding seat 43 is arranged on the slide seat of the first pneumatic slide table 42. A second pneumatic slide table 44 arranged vertically is arranged on the L-shaped sliding seat 43. A fixed seat 45 is arranged on the slide seat of the second pneumatic slide table 44. An impurity removal pipe 46 arranged obliquely is arranged on the fixed seat 45. The upper end of the impurity removal pipe 46 is connected to the air inlet of the dust suction fan 41 through a hose 47. In this way, the impurity removal pipe 46 can be driven to move in the length direction and the vertical direction of the cross beam 20 through the first pneumatic slide table 42 and the second pneumatic slide table 44, so that the impurity removal pipe 46 can reach any position of the withering trough.
[0030] A horizontally arranged first cable carrier 48 is provided on the side of the cross beam 20. One end of the first cable carrier 48 is fixed on the side of the cross beam 20 near the sliding bracket 10, and the other end is fixed on the L-shaped sliding seat 43. A vertically arranged second cable carrier 49 is provided on the side of the L-shaped sliding seat 43. One end of the second cable carrier 49 is fixed at the upper end of the L-shaped sliding seat 43, and the other end is fixed on the fixed seat 45. The hose 47 passes through the first cable carrier 48 and the second cable carrier 49 in sequence from the air inlet of the dust suction fan 41 and is connected to the upper end of the impurity removal pipe 46. In this way, when the impurity removal pipe 46 moves in the length direction and the vertical direction of the cross beam 20, the hose 47 will move along with the first cable carrier 48 and the second cable carrier 49, thereby ensuring the smoothness of the hose 47. To further improve the impurity removal effect of the impurity removal pipe 46, the pipe orifice of the impurity removal pipe 46 is set to be flat.
[0031] Furthermore, a rotary bearing 14 is provided on the top of the sliding bracket 10. The outer ring of the rotary bearing 14 is fixedly connected to the top of the sliding bracket 10, and the inner ring is fixedly connected to the end of the cross beam 20. A rotary motor 15 is provided inside the sliding bracket 10. The output shaft of the rotary motor 15 passes through the top of the sliding bracket 10 and is fixedly connected to the inner ring of the rotary bearing 14. By driving the inner ring of the rotary bearing 14 to rotate through the rotary motor 15, the cross beam 20 can be driven to rotate around the rotary bearing 14. In this way, when laying fresh tea leaves into the withering trough, the cross beam 20 can be driven to rotate with the identification component 30 and the impurity removal component 40 to the side of the tea withering machine for avoidance.
[0032] To obtain more information about the fresh tea leaves during withering, a temperature sensor, a humidity sensor, a ranging sensor, etc. can also be provided at the bottom of the L-shaped sliding seat 43. In this way, the temperature, humidity information and leaf layer thickness of the fresh tea leaves can be collected during the impurity removal process.
[0033] The working principle of an automatic detection and impurity removal device for the tea withering link in this embodiment is as follows: In the initial state, the sliding bracket 10 moves to one end of the tea withering machine, the cross beam 20 is located on the side of the tea withering machine and is consistent with the length direction of the tea withering machine, and the cover door panel 36 of the dust-proof cover 33 is in the closed state. After the fresh tea leaves are well withered in the withering trough, the rotary motor 15 drives the cross beam 20 to rotate to a state perpendicular to the length direction of the withering trough above the withering trough; the rotating motor 37 drives the cover door panel 36 to open, the identification camera 32 starts to take pictures of the fresh tea leaf images. After identifying the impurity information, the first pneumatic slide 42 and the second pneumatic slide 44 drive the impurity removal pipe 46 to move to a position where the pipe orifice is close to the impurity. The dust suction fan 41 is started to suck away the impurities. The impurities reach the collection box of the dust suction fan 41 through the impurity removal pipe 46 and the hose 47.
[0034] Embodiment Two
[0035] As Figure 7As shown in the figure, an automatic detection and impurity removal device for the tea withering process disclosed in this embodiment has basically the same structure as that of the first embodiment, except that the recognition component 30 further includes a third pneumatic slide 60 arranged on the cross beam 20, and the mounting bracket 31 is fixedly arranged on the slide seat of the third pneumatic slide 60. In this way, the mounting bracket 31 and the recognition camera 32 can be driven to move along the length direction of the cross beam 20 by the third pneumatic slide 60, that is, the recognition camera 32 can move in the width direction of the withering trough of the tea withering machine. In this way, when dealing with a tea withering machine with a relatively large width, the recognition requirements for the fresh tea leaves on the entire withering trough can be met by the lateral movement of the recognition camera 32.
[0036] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
