[0003] There are many links in tea processing, generally including spreading, killing, rolling, drying, etc. In order to improve the efficiency of tea processing, most tea processing factories form a complete set of tea processing production lines by purchasing tea processing equipment for each process. However, these processes are currently mainly mechanized processing designed based on manual experience, and it is impossible to adjust the working parameters of the equipment according to the actual situation of the tea products. Generally, workers are required to test the tea products of each process in order to roughly obtain parameter information such as the moisture content and leaf shape of the tea products, so as to determine whether the processing parameters of the next process need to be adjusted. However, this kind of testing often requires workers to have rich experience, which not only increases the labor intensity of workers, but also increases production costs. Even if the workers are experienced, manual testing is still prone to errors, resulting in poor overall quality of tea processed through the production line. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-10 As shown, the embodiment of the present application discloses a self-propelled detection device for a tea processing production line, including a walking mechanism 10, a frame 20, a sampling component 70, a leaf shape detection component 30, a transfer component 40, a moisture content detection component 50, a recovery mechanism 60 and a communication control module (not shown in the figure). The walking mechanism 10 is a mobile trolley for supporting various components and controlling the movement of the entire detection device. An automatic driving system, an automatic navigation system, and a road condition monitoring system are configured thereon. The walking path can be planned through a remote control terminal, and the walking path can be walked according to the predetermined path. The surrounding road conditions can be monitored in real time and obstacles can be avoided automatically. The frame 20 is arranged on the walking mechanism 10, and is used to install the sampling component 70, the leaf shape detection component 30, the transfer component 40, the moisture content detection component 50, the recovery mechanism 60, the communication control module, etc. The sampling component 70 is used to absorb the tea in-process on the tea processing production line and place it on the leaf shape detection component 30. The leaf shape detection component 30 is used to obtain image information of the tea in-process. The transport component 40 is used to transport the tea leaves in product after detection by the leaf shape detection component 30 to the moisture content detection component 50. The moisture content detection component 50 is used to obtain the moisture content information of the tea leaves in product. The recovery mechanism 60 is used to transport the tea leaves in product after detection by the moisture content detection component 50 back to the tea processing production line. The communication control module is used to receive instructions from the remote control terminal to control the walking mechanism 10; receive and process the image information taken by the leaf shape detection component 30 and the moisture content detection component 50, and transmit it to the remote display terminal; control the actions of the various moving parts of the sampling component 70, the leaf shape detection component 30, the transport component 40, the moisture content detection component 50, and the recovery mechanism 60.

[0031] Specifically, the sampling assembly 70 includes a fixed seat 71 arranged on the top of the frame 20, a mechanical arm 72 is rotatably arranged on the fixed seat 71, a sampling plate 73 is arranged at the suspension end of the mechanical arm 72, and a plurality of suction cups 74 are arranged in an array at the bottom of the sampling plate 73, and the plurality of suction cups 74 are connected to an air pump (not shown in the figure) through an air pipe (not shown in the figure). When sampling, the sampling plate 73 is moved to the top of the tea processing production line through the rotation and extension of the mechanical arm 72, and then the sampling plate 73 and the suction cup 74 are driven to move downward, and when the suction cup 74 contacts the tea product, the air pump is started to adsorb the tea product on the suction cup 74. There are 9 suction cups 74, which are arranged in a 3*3 array, and a certain distance is spaced between two adjacent suction cups 74, so that the sampling range can be expanded during sampling and the representativeness of the sample can be improved; secondly, when the sample is placed on the leaf shape detection assembly 30 for leaf shape detection, the sample is placed at intervals without stacking, thereby avoiding the image overlap caused by the staggered samples, and effectively improving the accuracy of leaf shape detection. In addition, an infrared detector 80 arranged obliquely is provided on the sampling plate 73. The movement of the robotic arm 72 can drive the infrared detector 80 to reach the production line above the tea leaves in production, so that the infrared detector 80 can be used to measure the thickness and leaf temperature of the tea leaves in production line.

[0032] The leaf shape detection assembly 30 includes a base 31 disposed in the frame 20, and two vertical plates 32 are disposed on the base 31, and the plate surfaces of the two vertical plates 32 are parallel and spaced apart. A slide groove 33 is provided on the plate surfaces of the two vertical plates 32, and the slide groove 33 is divided into a horizontal section 331 and an arc section 332 from the outside to the inside. A detection platform 34 is slidably disposed in the two slide grooves 33, and the detection platform 34 includes a first detection plate 341 and two side plates 342 located at the bottom of the first detection plate 341. The two side plates 342 are protruded downward from the bottom of the first detection plate 341 near the inner side of the vertical plate 32, and the plate surfaces of the side plates 342 are parallel to and close to the plate surfaces of the corresponding vertical plates 32. The width of the first detection plate 341 is greater than the spacing between the two vertical plates 32, so as to prevent the tea sample from falling onto the base 31.

[0033] A first sliding shaft 343 is rotatably arranged at one end of the two side plates 342 near the transfer assembly 40, and the two ends of the first sliding shaft 343 extend outwardly into the slide grooves 33 of the two vertical plates 32; a strip groove 344 is also opened on the plate surface of the side plate 342 from the outside to the inside, and the height of the strip groove 344 is consistent with the height of the horizontal section 331 of the slide groove 33, and a second sliding shaft 345 is slidably arranged in the two strip grooves 344, and the two ends of the second sliding shaft 345 extend outwardly into the slide grooves 33 of the two vertical plates 32; through the first sliding shaft 343 and the second sliding shaft 345, the detection platform 34 can slide along the slide groove 33. In the initial state, the first sliding shaft 343 and the second sliding shaft 345 are respectively located at the two ends of the horizontal section 331 of the slide groove 33, and at this time, the detection platform 34 is completely located above the base 31 and is also located in the frame 20, which is convenient for protection. When sampling, the detection platform 34 slides toward the outside of the frame 20 in the horizontal section 331 of the slide slot 33. Since the second sliding shaft 345 has been parked at the outer end of the horizontal section 331 of the slide slot 33, when the detection platform 34 slides outward, the second sliding shaft 345 can no longer continue to move outward. At this time, under the action of the strip groove 344, only the detection platform 34 and the first sliding shaft 343 move outward. When the inner end of the strip groove 344 contacts the second sliding shaft 345, the detection platform 34 moves outward to the maximum position. At this time, the first detection plate 341 extends out of the frame 20 to receive the tea sample obtained by the sampling assembly 70. This position is the sampling position of the detection platform 34. In the specific setting, the inner end of the strip groove 344 is spaced apart from the first sliding shaft 343, so that when the detection platform 34 moves outward to the maximum position, there is a certain distance between the first sliding shaft 343 and the second sliding shaft 345, which can ensure the stability of the detection platform 34 in the sampling position. An industrial camera 35 is arranged at the top of the frame 20, just above the middle of the base 31. After sampling, the detection platform 34 moves to the inside of the frame 20 to below the industrial camera 35. This position is the detection position of the detection platform 34. Then the industrial camera 35 takes the image of the tea sample on the first detection plate 341, transmits it to the communication control module for processing and analysis, and obtains the leaf shape information of the tea sample. After the shooting is completed, the detection platform 34 continues to move to the inside of the frame 20 to transport the tea sample to the transfer component 40.

[0034] Specifically, a limit bar 38 is provided on the outer plate surface of the vertical plate 32 at the inner end of the horizontal section 331 of the slide groove 33, and the limit bar 38 is located between the first sliding shaft 343 and the second sliding shaft 345, and a limit column 346 is provided on the end surface of the second sliding shaft 345 protruding outward. When the detection platform 34 continues to move inward, the first sliding shaft 343 enters the arc section 332 of the slide groove 33, so that the detection platform 34 begins to tilt; the limit bar 38 cooperates with the limit column 346 so that the second sliding shaft 345 can only stay outside the limit bar 38, so that the second sliding shaft 345 and the first sliding shaft 343 can avoid entering the arc section 332 of the slide groove 33 at the same time, causing the detection platform 34 to become unstable. When the first sliding shaft 343 slides to the lowest end of the arc section 332, the second sliding shaft 345 is located outside the limit bar 38 and at the outer end of the strip groove 344. At this time, the first detection plate 341 reaches the maximum tilt angle, and this position is the feeding position of the detection platform 34. When the first detection plate 341 is tilted, the tea samples thereon will slide down under the action of gravity and finally slide onto the transfer component 40 .

[0035] A driving mechanism 36 is also provided between the two vertical plates 32. The driving mechanism 36 includes a bracket 361 provided between the two vertical plates 32. The bracket 361 is provided at a corner below the arc segment 332 of the slide 33 and is provided in an arc shape consistent with the arc segment 332. Rotating wheels (not shown in the figure) are provided at the other three corners of the bracket 361. A synchronous belt 362 is provided on the plurality of rotating wheels, so that the upper side of the synchronous belt 362 is consistent with the direction of the slide 33. A driving motor 363 is provided on the base 31. A driving gear 364 is provided on the output shaft of the driving motor 363. The driving gear 364 meshes with the inner teeth of the synchronous belt 362. The driving motor 363 drives the driving gear 364 to rotate, thereby driving the synchronous belt 362 to rotate. The shaft body of the first sliding shaft 343 and the synchronous belt 362 are connected by a connecting block 37, so that the rotation of the synchronous belt 362 can drive the first sliding shaft 343 to move in the slide groove 33, thereby driving the detection platform 34 to move. The detection platform 34 can be controlled to slide back and forth in the slide groove 33 by controlling the forward and reverse rotation of the drive motor 363.

[0036] The transfer assembly 40 includes a mounting seat 41 disposed on the base 31, an electromagnetic vibrator 42 is disposed on the mounting seat 41, a feed trough 43 is disposed on the electromagnetic vibrator 42, and the feed trough 43 is divided into a variable diameter section 431 and a gentle section 432 from the leaf shape detection assembly 30 to the moisture content detection assembly 50. The variable diameter section 431 extends toward the vertical plate 32, and its slope is consistent with the slope of the first detection plate 341 when the first sliding shaft 343 slides to the lowest end of the arc section 332 of the slide trough 33, and its width at one end adjacent to the vertical plate 32 is greater than the width of the surface of the detection table 34, so that when the first detection plate 341 is tilted, the tea leaves on the first detection plate 341 will slide down and finally slide onto the variable diameter section 431 of the feed trough 43. When the first detection plate 341 reaches the maximum tilt angle, the bottom surface of the first detection plate 341 is against the bottom of the feeding trough 43, so that when the electromagnetic vibrator 42 vibrates, it will drive the first detection plate 341 to vibrate, so that when part of the tea sample stays on the first detection plate 341, the vibration of the first detection plate 341 can make the part of the tea sample slide onto the feeding trough 43. It is further configured that a vertical rib is also provided on the side of the feeding trough 43 to prevent the tea sample from falling from the side. The width of the end of the variable diameter section 431 away from the vertical plate 32 is smaller than the width of the first detection plate 341, the width of the flat section 432 is consistent with the width of the end of the variable diameter section 431, and the slope of the flat section 432 is smaller than the slope of the variable diameter section 431, so that the tea sample will accumulate at the interface between the variable diameter section 431 and the flat section 432 after sliding down from the variable diameter section 431, thereby achieving the purpose of gathering the tea samples, and then the electromagnetic vibrator 42 is used to make the tea sample move at a uniform speed from the flat section 432 to the moisture content detection component 50.

[0037] The moisture content detection component 50 includes an electric slide 51 arranged at the bottom of the frame 20, and the length direction of the electric slide 51 is consistent with the transportation direction of the transfer component 40; a vertically arranged electric push cylinder 52 is arranged on the slide seat of the electric slide 51, and a second detection plate 53 is arranged at the end of the push rod of the electric push cylinder 52. In the initial state, the slide seat of the electric slide 51 is located near one end of the leaf shape detection component 30, and the second detection plate 53 is located below the transfer component 40. When the tea sample reaches the flat section 432 of the feed trough 43, the electric slide 51 starts to drive the electric push cylinder 52 and the second detection plate 53 to move away from the leaf shape detection component 30, so that the tea sample is slowly spread on the second detection plate 53 from the outlet of the flat section 432 of the feed trough 43, realizing the collection and transportation of the tea sample from the leaf shape detection component 30 to the moisture content detection component 50. A spectrum camera 54 is arranged on the top of the frame 20. When the slide seat of the electric slide 51 moves to the end away from the leaf shape detection assembly 30, the spectrum camera 54 is located directly above the second detection plate 53. Then the electric push cylinder 52 drives the second detection plate 53 to rise to the position close to the spectrum camera 54. The spectrum camera 54 takes an image of the tea sample and transmits it to the communication control module for processing and analysis to obtain the moisture content information of the tea sample.

[0038] The recycling mechanism 60 includes a recycling box 61 arranged on the top of the frame 20, a suction fan 62 is arranged on the top of the recycling box 61, and a suction pipe 63 is arranged on the side. The suction pipe 63 passes through the top of the frame 20 and extends downward into the frame 20, and a suction hopper 64 is arranged at the end. A horizontally arranged first push rod 65 is fixedly arranged on the side of the frame 20, and a connecting plate 651 is arranged at the push rod end of the first push rod 65, and the connecting plate 651 is fixedly connected to the lower end of the suction pipe 63. The bottom of the recycling box 61 is opened and provided with a bottom plate, and one side of the bottom plate is hinged to the side of the bottom of the recycling box 61. A driving component for driving the bottom plate to rotate is arranged on the side of the recycling box 61. The tea samples recycled into the recycling box 61 will be accumulated on the bottom plate. At this time, it is only necessary to drive the bottom plate to rotate through the driving component to make the bottom plate tilt downward to pour out the tea samples. A recovery hopper 66 is provided below the bottom plate, a return pipe 67 is connected to the bottom of the recovery hopper 66, a second push rod 68 is provided on the side of the frame 20, a mounting block 681 is provided at the push rod end of the second push rod 68, and the mounting block 681 is fixedly connected to the return pipe 67. Specifically, after the moisture content detection assembly 50 completes the detection, the electric push cylinder 52 drives the second detection plate 53 to descend to the height of the suction hopper 64, the first push rod 65 pushes the suction pipe 63 and the suction hopper 64 to move toward the second detection plate 53, the suction fan 62 is started, and the tea sample on the second detection plate 53 is sucked into the recovery box 61 through the suction hopper 64 and the suction pipe 63; then the second push rod 68 pushes the return pipe 67 to move to the top of the tea processing production line, the bottom plate at the bottom of the recovery box 61 is opened, and the tea sample on the bottom plate is poured into the recovery hopper 66, and returns to the tea processing production line along the return pipe 67, so as to realize the recovery of the tea sample and avoid waste.
