Description

Technical Field

[0001] The present application relates to the technical field of tea fermentation, and more particularly to an intelligent Pu'er tea fermentation and compost turning machine. Background Art

[0002] Pu'er tea is a national geographical indication protected product. It is a post-fermented tea made by fermenting sun-dried green tea through tide and pile fermentation, and then turning and fermenting the pile at the right time. Pu'er tea pile turning is generally carried out 4-8 times. The tea leaves to be fermented need to be piled to a certain height before fermentation.

[0003] In the prior art, tea leaf turning is achieved by lifting the tea leaves when a roller with a turning blade passes through the fermented tea leaves to loosen the tea leaves, such as patent number: CN204763169U, named tea leaf turning mechanism. However, the device needs to move the fermentation vehicle or the roller during operation. The bottom edge of the fermentation vehicle is at right angles to the side of the fermentation vehicle, and the cross-section of the roller is circular. Therefore, the tea leaves at the bottom edge of the fermentation vehicle cannot be scraped by the roller, and there is a dead angle for turning the tea leaves, resulting in that the tea leaves in the fermentation vehicle cannot be fully turned.

[0004] For example, the patent number is CN117223775A, and the name is intelligent Pu'er tea fermentation and compost turning integrated machine, which also uses a conveyor belt with a tea trough to load and transport tea leaves. The tea trough is separated by a partition. When the conveyor belt is loaded with tea leaves, the partition also needs to rotate around the roller at one end of the conveyor belt, and there is also a dead corner for turning the compost, and the tea leaves at the bottom edge of the fermentation vehicle cannot be fully loaded.

[0058] The present application makes improvements and innovations and proposes the following embodiments.

[0059] In some embodiments, see Figure 1-Figure 13 , provides an intelligent Pu'er tea fermentation and compost turning machine, including:

[0060] Fermentation vehicle 1 for loading Pu'er tea;

[0061] A fermentation room 2 for providing a fermentation environment for Pu'er tea, a fermentation vehicle 1 is stored in the fermentation room 2, the fermentation room 2 has an inlet and an outlet, the inlet and the outlet are connected through a conveying passage 21, and the fermentation vehicle 1 can move on the conveying passage 21;

[0062] A gantry 3, the gantry 3 having a passage 33 for the fermentation vehicle 1 to pass through, and the gantry 3 is erected above the conveying passage 21;

[0063] A first cylinder 4 having a first slide groove 41, the first cylinder 4 extends in the horizontal direction, one end of the first cylinder 4 is fixedly connected to the lower part of the gantry 3, and the other end is fixedly connected to a first motor 42, a first screw rod 43 is arranged in the first cylinder 4, and the first screw rod 43 is transmission-connected to the first motor 42; a first slider 44 is threadedly connected to the first screw rod 43, and the first slider 44 is slidably connected to the first slide groove 41;

[0064] A second cylinder 5 having a second slide groove 51, the second cylinder 5 extends in the vertical direction, one end of the second cylinder 5 is fixedly connected to the first slider 44, and the other end is fixedly connected to the second motor 52, a second screw rod 53 is arranged in the second cylinder 5, and the second screw rod 53 is transmission-connected to the second motor 52; a second slider 54 is threadedly connected to the second screw rod 53, and the second slider 54 is slidably connected to the second slide groove 51;

[0065] A connecting frame 6, the connecting frame 6 is fixedly connected to the second slider 54, and a third motor 61 is fixedly disposed on the connecting frame 6;

[0066] The compost turning rod 7 has a stirring blade 71, which extends in the horizontal direction. The compost turning rod 7 is rotatably connected to the connecting frame 6, and the compost turning rod 7 is transmission-connected to the third motor 61. There are multiple compost turning rods 7, and the multiple compost turning rods 7 are arranged in sequence and spaced apart along the extension direction of the channel 33.

[0067] By setting the first barrel 4, the first screw rod 43, and the first motor 42, the compost turning rod 7 is driven to move horizontally to insert the bottom of the fermented tea leaves, and then the second barrel 5, the second screw rod 53, and the second motor 52 are matched to drive the compost turning rod 7 to move in the vertical direction to lift the fermented tea leaves, and finally the third motor 61 is matched to drive the stirring blade 71 to rotate so that the fermented tea leaves are scattered and fall onto the fermentation vehicle 1, thereby achieving the loosening and compost turning of the fermented tea leaves. Since the compost turning rod 7 can move in the horizontal and vertical directions, the compost turning effect with the large-sized roller can be achieved, so the present application can make the size of the compost turning rod 7 smaller, and then the compost turning rod 7 can be arranged near the intersection of the bottom and the side wall of the fermentation vehicle 1, so the compost turning rod 7 can fully compost the fermented tea leaves located there. Arranging multiple compost turning rods 7 can improve the compost turning efficiency and make the compost turning more uniform.

[0068] By inserting the compost turning rod 7 into the fermented tea leaves and then lifting and turning the compost, the process of manual compost turning is simulated, the traditional skills and techniques are guaranteed as much as possible, and the traditional taste is restored as much as possible.

[0069] Among them, see Figure 5 and Figure 6 , the number of the first cylinders 4 is two or four, the number of the second cylinders 5 corresponds to the number of the first cylinders 4, and the gantry 3 has four support columns 31; two first cylinders 4 are distributed on one side of the channel 33, and are fixedly connected to the corresponding support columns 31; or four first cylinders 4 are evenly distributed on both sides of the channel 33, and are fixedly connected to the corresponding support columns 31. When four first cylinders 4 are provided, the corresponding compost turning rods 7 on both sides of the channel 33 are arranged in an interlaced manner. When the compost turning rods 7 are inserted into the fermented tea leaves, it can ensure that the external forces exerted on the fermented tea leaves are basically offset, thereby reducing the occurrence of the fermented tea leaves being pushed to one side of the fermentation vehicle 1 by the inserted compost turning rods 7.

[0070] The connecting frame 6 extends along the extension direction of the channel 33, and a plurality of pile turning rods 7 are arranged at intervals along the extension direction of the connecting frame 6; two adjacent pile turning rods 7 are driven by a chain. One of the pile turning rods 7 is connected to the third motor 61 by a worm gear transmission. Arranging a plurality of pile turning rods 7 can improve the efficiency of pile turning and make the pile turning more uniform. The use of a worm gear transmission can change the transmission direction of the torque to better arrange the position of the third motor 61.

[0071] In the extending direction of the channel 33, the distance between the compost turning rods 7 at both ends is less than the length of the fermentation cart 1, but close, that is, after the compost turning rods 7 are inserted into the fermentation cart 1, the compost turning rods 7 at both ends are close to the edge of the fermentation cart 1. The compost turning rods 7 at both ends are close to the edge of the fermentation cart 1 to ensure that the compost turning rods 7 can more fully turn the fermented tea leaves at that position, thereby reducing the dead corner area of ​​compost turning.

[0072] A through hole 11 is provided on the side of the fermentation vehicle 1 for inserting the compost turning rod 7, and the through hole 11 is strip-shaped and extends in the vertical direction to facilitate the lifting and lowering movement of the compost turning rod 7. The through hole 11 is covered with a rubber layer, and the rubber layer is fixedly connected to one side edge of the through hole 11. The covering rubber layer can fit the edge of the through hole 11 when the compost turning rod 7 is not inserted. When the compost turning rod 7 is inserted, the rubber layer is pushed open, but due to the softness of the rubber layer, the rubber layer away from the compost turning rod 7 is still attached to the edge of the through hole 11 to reduce the fermented tea leaves from falling from the through hole 11.

[0073] In some embodiments, there are multiple stirring blades 71, and the multiple stirring blades 71 are spaced and fixedly arranged along the extending direction of the compost turning rod 7. Providing multiple stirring blades 71 can improve the uniformity of compost turning and improve the compost turning efficiency.

[0074] In some embodiments, there are multiple stirring blades 71, and the multiple stirring blades 71 can be extended or contracted in the radial direction of the compost turning rod 7, and a driving mechanism 8 for driving the stirring blades 71 to extend or contract is provided on the connecting frame 6. The stirring blades 71 are configured to be retractable and extendable, and when the stirring blades 71 are retracted and then inserted into the fermented tea leaves, the insertion resistance can be reduced, and at the same time, the damage to the tea leaves when the stirring blades 71 are inserted is reduced, and the generation of broken leaves is reduced.

[0075] In some embodiments, see Figure 7-10 The driving mechanism 8 includes a fourth motor 81, a third screw rod 82, a third slider 83, a push plate 84, and a moving rod 85; the fourth motor 81 is fixedly connected to the connecting frame 6, the output end of the fourth motor 81 is transmission-connected to the third screw rod 82, the third screw rod 82 is rotationally connected to the connecting frame 6, the third slider 83 is threadedly connected to the third screw rod 82, and the third slider 83 is fixedly connected to the push plate 84; the interior of the compost turning rod 7 is a hollow structure, the moving rod 85 is movably inserted in the compost turning rod 7 to drive the stirring blade 71 to extend or contract, and the moving rod 85 is rotationally connected to the push plate 84. The stirring blade 71 is pushed to extend or contract by the mutual cooperation of the fourth motor 81, the third screw rod 82, the third slider 83, the push plate 84, and the moving rod 85, which has a simple structure, reasonable design, and is practical and reliable.

[0076] In some embodiments, see Figure 7 and Figure 8The plurality of stirring blades 71 are rotatably connected to the compost turning rod 7 via the rotating shaft 72. The rotating shaft 72 and the moving rod 85 are both provided with teeth, and the rotating shaft 72 and the moving rod 85 are meshed and connected. The rotating shaft 72 is driven to rotate by the telescopic movement of the moving rod 85, and finally the stirring blades 71 are driven to rotate, so that the extending direction of the stirring blades 71 is perpendicular to or coincides with the extending direction of the compost turning rod 7, thereby realizing the function of extending or contracting the stirring blades 71.

[0077] In some embodiments, see Fig. 9 and Fig.10 Among the multiple stirring blades 71, the middle parts of every two stirring blades 71 are hinged together through the hinge shaft 73, and the stirring blades 71 are arranged in sequence along the extension direction of the compost turning rod 7, and the ends of two adjacent stirring blades 71 are hinged together; two connecting rods 74 are hinged on the moving rod 85, and the two connecting rods 74 are hinged with the two stirring blades 71 respectively. The compost turning rod 7 is provided with a limiting groove 75, and the hinge shaft 73 is slidably connected with the limiting groove 75. The connecting rod 74 is driven to rotate and move by the telescopic movement of the movement, and the connecting rod 74 further drives the two stirring blades 71 to rotate around the hinge shaft 73 to change the angle between the extension direction of the stirring blade 71 and the extension direction of the compost turning rod 7. When the angle gradually increases, it means that the extension process is in progress, and when the angle gradually decreases, it means that the contraction process is in progress. During the rotation of the stirring blade 71, the hinge shaft 72 will move in the extension direction of the compost turning rod 7. The limiting groove 75 can limit the moving direction of the hinge shaft 73. At the same time, the limiting groove 75 can limit the hinge shaft 73 from escaping from the limiting groove 75, thereby ensuring that the stirring blade 71 is detached from the compost turning rod 7.

[0078] A strip-shaped notch is provided on the side of the limiting groove 75 , and a protrusion is provided on the hinge shaft 73 . When the hinge shaft 73 is inserted into the limiting groove 75 , the protrusion is just inserted into the notch, so that the hinge shaft 73 cannot be separated from the limiting groove 75 .

[0079] In some embodiments, a heater 22 and a sprayer 23 are provided in the fermentation room 2. The heater 22 and the sprayer 23 can adjust the temperature and humidity in the fermentation room 2 to ensure that the fermentation environment is in an optimal state.

[0080] Specifically, the sprayer 23 includes a water pipe, a solenoid valve 93 arranged on the water pipe, and an atomizing nozzle connected to the water pipe, and the atomizing nozzle is fixedly connected to the upper part of the fermentation room 2. It is ensured that the sprayed water mist can better fill the entire fermentation room 2.

[0081] Specifically, a roller conveyor belt is provided in the fermentation room 2; the fermentation vehicle 1 and the fermentation room 2 are both provided with a temperature sensor 91 and a humidity sensor 92, and the fermentation room 2 is also provided with a processor 9, and the temperature sensor 91, the humidity sensor 92, the heater 22, and the sprayer 23 are all electrically connected to the processor 9. The probes of the temperature sensor 91 and the humidity sensor 92 on the fermentation vehicle 1 are both located inside the fermented tea leaves, and are used to obtain the temperature and humidity conditions inside the fermented tea leaves. The temperature and humidity conditions of the fermented tea leaves are monitored in real time. The roller conveyor belt provided in the fermentation room 2 facilitates the movement of the fermentation vehicle 1, and facilitates the movement of the fermentation vehicle 1 to a suitable position, so as to accommodate more fermentation vehicles 1. The processor 9 compares the signals transmitted by the temperature sensor 91 and the humidity sensor 92 with the set values, and starts the heater 22 and / or the sprayer 23 if the temperature value and / or humidity value in the fermentation room 2 is lower than the corresponding set values. If the temperature value and / or humidity value on the fermentation cart 1 is lower than the corresponding set value, the corresponding signal will be transmitted to the staff's terminal to notify the staff that the temperature value and / or humidity value of the corresponding fermentation cart 1 is lower than the corresponding set value. After receiving the corresponding situation, the staff will heat and / or humidify the fermented tea leaves in the corresponding fermentation cart 1.

[0082] The temperature sensor 91 and the humidity sensor 92 on the fermentation vehicle 1 are both electrically connected to the processor 9 via wireless transmission, and the processor 9 is also electrically connected to the terminal via wireless transmission.

[0083] The specific staff determines the number of compost turning and the amount of watering according to the temperature and humidity of the fermented tea leaves in the corresponding fermentation vehicle 1. That is, when the temperature is too high, the fermented tea leaves can be turned over several times to dissipate excess heat. If the moisture content of the fermented tea leaves is low, the staff can add water appropriately during the compost turning process.

[0084] In some embodiments, a lifting device 24 is provided in the fermentation room 2; the lifting device 24 includes four sprockets 241, a lifting block 242, and a loading plate 243 that are spaced apart from each other; the sprocket 241 is arranged in the vertical direction, the sprocket 241 is transmission-connected to a driving motor 244, the lifting block 242 is fixedly connected to the sprocket 241; the loading plate 243 is supported on the lifting block 242, and the loading plate 243 can load the fermentation vehicle 1. By providing the sprocket 241, the lifting block 242, and the loading plate 243, the fermentation vehicle 1 is arranged vertically, ensuring that a smaller floor space is used to accommodate more fermentation vehicles 1.

[0085] Specifically, the sprocket 241 includes a chain and a gear, and the lifting block 242 is fixedly connected to the chain; the four sprockets 241 are distributed at the four corners of the rectangle; each sprocket 241 is provided with a plurality of lifting blocks 242 of different sizes at intervals, the size of the carrier plate 243 decreases from top to bottom, and the size of the lifting block 242 increases successively; the carrier plate 243 is a roller conveyor belt; the driving motor 244 realizes the synchronous transmission of the four sprockets 241 through the transmission rod 245, that is, the two ends of the two transmission rods 245 are respectively connected to four gears, and the two transmission rods 245 are respectively connected to a driving motor 244, and the output end of the driving motor 244 and the transmission rod 245 are driven by a worm gear. The four sprockets 241 are distributed in a rectangular shape, which can make the carrier plate 243 more uniformly stressed. Multiple lifting blocks 242 are arranged at intervals on each sprocket 241, which can accommodate multiple carrier plates 243, thereby improving the accommodating capacity of the fermentation room 2 and making full use of the accommodating space of the fermentation room 2. The output end of the driving motor 244 and the transmission rod 245 are connected through a worm gear transmission, which can not only change the torque transmission direction of the driving motor 244, but also ensure that after the chain lifts the carrier plate 243 to the specified position and the motor stops rotating, the sprocket 241 will not rotate, thereby ensuring that the carrier plate 243 will not fall.

[0086] Multiple lifting blocks 242 and carrier plates 243 of different sizes can ensure that the corresponding lifting block 242 can only place the carrier plate 243 of the corresponding size during the movement of the chain.

[0087] In some embodiments, the conveying passage 21 includes: a feed channel 211, a discharge channel 213, and a connecting channel 212; one end of the feed channel 211 is connected to the inlet, and the other end is connected to the connecting channel 212; one end of the discharge channel 213 is connected to the outlet, and the other end is connected to the connecting channel 212; the gantry 3 is erected above the feed channel 211.

The adapter 78 is coated on the water inlet of the compost turning rod 7. The inside of the adapter 78 has a cavity. When the adapter 78 is sleeved outside the compost turning rod 7, the cavity and the outer wall of the compost turning rod 7 are enclosed to form a closed annular chamber. When the compost turning rod 7 is rotated to any position, the water inlet is connected to the cavity. The internal hollow of the compost turning rod 7 is a closed structure. The compost turning rod 7 is provided with a nozzle 77 connected to the inside of the compost turning rod 7. The water pipe 76 and the nozzle 77 are arranged in the compost turning rod 7 to make water replenishment during the compost turning process. This water replenishment method is more uniform than the water replenishment method after compost turning. It can also reduce the situation where manual watering is required after compost turning, reducing labor intensity.

[0091] When the humidity value transmitted by the fermentation vehicle 1 is less than the set value, the processor 9 controls the electric valve to open during the compost turning process, the nozzle 77 discharges water, and the compost turning rod 7 replenishes water when turning the fermented tea leaves. The automation and intelligence of the Pu'er tea fermentation and compost turning machine are improved.

[0092] In some embodiments, a lifting mechanism 214 is further provided at both ends of the connecting channel 212; the lifting mechanism 214 includes a hydraulic cylinder 2141, a bracket 2142, and a conveying roller 2143; the hydraulic cylinder 2141 is placed on the ground, the telescopic end of the hydraulic cylinder 2141 is fixedly connected to the bracket 2142, and the conveying roller 2143 is installed on the top of the bracket 2142. Before the fermentation is completed, the fermentation vehicle 1 moving on the discharge channel 213 is lifted by the lifting mechanism 214 and transferred to the connecting channel 212 when passing through the lifting mechanism 214. After the fermentation vehicle 1 is received by the mechanism on the other end of the connecting channel 212, the fermentation vehicle 1 is transferred to the feed channel 211. The movement direction of the fermentation vehicle 1 is changed by lifting and lowering the hydraulic cylinder 2141 and coordinating with the conveying of the conveying roller 2143. The design is reasonable and the structure is simple.

[0093] The conveying roller 2143 is located on the feed channel 211 and the discharge channel 213.
