Description

Technical Field

[0001] The invention relates to the technical field of tea production, in particular to a tea leaf crushing device for tea production. Background Art

[0002] In the tea production process, the tea leaf crushing device plays a vital role, which directly affects the subsequent processing quality of tea leaves and the quality of the final product. The traditional tea leaf crushing device used in tea production mainly relies on a simple mechanical structure, such as crushing tea leaves by a single rotating blade or a drum. Although this prior art crushing device can meet the basic crushing needs to a certain extent, it has obvious defects. On the one hand, traditional crushing devices can usually only achieve unidirectional crushing of tea leaves, that is, the crushing knife or drum only rotates in a fixed direction and speed, resulting in limited crushing effect and efficiency. This unidirectional crushing method often cannot fully cover all parts of the tea leaves, easily causing large pieces to remain, affecting the uniformity and fineness of the crushed tea leaves. At the same time, due to the limitations of crushing speed and frequency, traditional devices need to consume more time and energy to complete the crushing task, reducing the overall production efficiency. On the other hand, traditional crushing devices lack flexibility and specificity in the process of tea transportation and crushing. Factors such as the shape, hardness and water content of the tea will affect the crushing effect, and traditional devices are often unable to dynamically adjust according to these changes. This causes the tea leaves to easily become blocked or piled up during the crushing process, which not only affects the crushing efficiency but may also cause damage to the equipment.

[0007] As a further preferred embodiment of the present technical solution, a positioning gear is fixedly connected to the bottom end of the positioning rod, and both sides of the positioning gear are meshingly connected with self-rotating gears fixedly installed on the movable rod.

[0008] As a further preferred embodiment of the present technical solution, a fixed tube is fixedly connected to the bottom end of the positioning gear, and the fixed tube, the inner wall of the fixed tube is provided with a first spiral blade fixedly mounted on the driving rod, and discharge pipes located above the crushing knife are provided on both sides of the top of the fixed tube.

[0012] Compared with the prior art, it has the following beneficial effects: The linkage between the active gear driven by the servo motor and the gear ring, self-rotating gear, crushing knife and other components realizes the composite motion of self-rotation and revolution of the crushing knife. This composite motion not only improves the cutting speed and frequency of the crushing knife, but also greatly reduces the time and energy required for crushing, and significantly improves the crushing efficiency. The composite motion of self-rotation and revolution and the adjustability of the crushing knife angle enable the crushing process to cover all parts of the tea leaves more comprehensively, reduce large pieces of residue, and improve the uniformity and fineness of the crushed tea leaves. This uniform crushing effect is crucial for subsequent processing. The coordinated action of the guide rod, reciprocating block, first damping spring and other components enables the crushing knife to reciprocate while moving up and down, thereby dynamically adjusting the crushing angle. This flexibility enables the system to carry out targeted crushing according to the shape and hardness of the tea leaves, reducing ineffective crushing time and further improving crushing efficiency.

[0013] The first spiral blade driven by the second synchronous belt transmission member not only realizes the upward conveyance of the tea leaves, but also performs additional crushing treatment during the conveying process. This continuous crushing and conveying process ensures that the tea leaves are fully and evenly crushed before reaching the final product form, thereby improving the overall crushing effect. The rotation of the first spiral blade not only promotes the conveyance of the tea leaves, but also promotes the initial mixing and dispersion of the tea leaves, improving its fluidity during the crushing process, which helps to reduce the risk of blockage and accumulation and improve the stability and reliability of the entire system.

[0014] The rotation of the driving rod is effectively transmitted to the reciprocating screw rod through the first synchronous belt wheel transmission member, so that it can realize synchronous rotation. This design ensures that the moving rod can realize accurate up and down movement on the support frame, thereby controlling the opening and closing of the cover plate. This intermittent opening and closing operation enables the tea leaves to be transported from the material box to the inside of the cylinder for crushing in a certain rhythm, which not only ensures the working efficiency of the crusher, but also avoids the problem of poor crushing effect or equipment overload caused by continuous and large-scale entry of tea leaves; by intermittently conveying tea leaves, the crusher can better control the amount of tea leaves crushed each time, making the crushing process more uniform and High efficiency, which helps to reduce the inadequate crushing or excessively large pieces of tea residue caused by too much tea, and also avoids the situation where the crushing efficiency is reduced due to too little tea. Therefore, this design significantly improves the crushing effect and ensures the uniformity of the final product; the setting of the toggle rod has a dispersion effect on the tea inside the material box, effectively preventing the accumulation and blockage of tea, which not only ensures the smooth flow of tea in the material box, but also avoids the problem of being unable to discharge due to excessive accumulation. At the same time, the dispersed tea leaves are easier to be evenly crushed during the transportation process, further improving the crushing efficiency and quality.

[0015] During the crushing process, the sealing cover seals the top of the discharge pipe, which effectively prevents material leakage during the crushing process and ensures the stability of the crushing environment and the consistency of the crushing effect. When the crushing is completed, the discharge channel is quickly opened through the cooperation of the cylinder and the moving wheel, which enables the timely discharge of the crushed material and prepares for the next crushing operation.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: a tea leaf crushing device for tea production, comprising a cylinder 1, a material box 2 is arranged on one side of the top of the cylinder 1, the function of the material box 2 is to store tea leaves to be processed, a positioning rod 3 is firmly connected to the top of the inner cavity of the cylinder 1, a crushing assembly 5 is installed at the bottom end of the positioning rod 3, which is the part of the whole device responsible for crushing tea leaves, a driving rod 4 is rotatably connected to the positioning rod 3, and a discharge assembly 6 is installed at the bottom end of the driving rod 4; The crushing assembly 5 includes a gear ring 51 rotatably mounted on the positioning rod 3, and movable rods 52 are rotatably connected to the two sides of the gear ring 51, and these movable rods 52 are slidably connected to spline rods 54 in the vertical direction. The bottom end of the spline rod 54 is fixedly connected to a rectangular rod 55, and a plurality of groups of toothed rods 56 are arranged on the outer wall of the rectangular rod 55. These toothed rods 56 are evenly distributed along the outer wall of the rectangular rod 55. A rotating groove 57 is opened on the outer wall of the movable rod 52, and a half gear 58 meshing with the toothed rod 56 is rotatably connected to the rotating groove 57, and a crushing knife 59 is fixedly connected to the outer end of the half gear 58; On the other side of the top of the cylinder 1, a mounting seat 514 is fixedly installed, and a servo motor 515 is fixedly installed on the mounting seat 514. The output end of the servo motor 515 is fixedly connected to a driving gear 516 meshing with one side of the gear ring 51 through a rotating shaft. The rotating shaft is connected to the driving rod 4 through a second synchronous pulley transmission member 517. This design is to ensure that the crushing assembly 5 can work efficiently and stably. The top upper end of the positioning rod 3 is fixedly connected with a reciprocating block 512, the top of the spline rod 54 is fixedly connected with a guide rod 511, the top of the guide rod 511 fits and slides with the bottom of the reciprocating block 512, and the bottom of the rectangular rod 55 is fixedly connected with a first damping spring 510. Under the action of elastic force, the first damping spring 510 pushes the rectangular rod 55, the spline rod 54, and the guide rod 511 to move upward, ensuring that the top of the guide rod 511 always fits and slides with the bottom outer wall of the reciprocating block 512; The bottom end of the positioning rod 3 is fixedly connected with a positioning gear 513, and both sides of the positioning gear 513 are meshedly connected with a self-rotating gear 53 fixedly installed on the movable rod 52. This design is to ensure that the crushing assembly 5 can maintain a stable rotation speed during the crushing process; The bottom end of the positioning gear 513 is fixedly connected to a fixed tube 518, and a first spiral blade 519 is fixedly installed on the inner wall of the fixed tube 518. This spiral blade is installed on the driving rod 4. Discharge pipes 520 located above the crushing knife 59 are arranged on both sides of the top of the fixed tube 518. This is the channel for the tea leaves to be discharged from the device after being crushed.

[0020] In the embodiment of the present invention, by starting the servo motor 515, the rotating shaft is driven and realizes synchronous rotation with the driving gear 516. The rotating force of the driving gear 516 is transmitted to the ring gear 51, so that it rotates on the positioning rod 3. In this process, the rotation of the ring gear 51 drives the synchronous rotation of the movable rod 52, the self-rotating gear 53 and the crushing knife 59. During the rotation process, the crushing knife 59 performs a crushing operation on the tea leaves inside the cylinder 1. At the same time, when the ring gear 51 revolves, the self-rotating gear 53 is meshed with the positioning gear 513, and the positioning gear 513 is fixedly installed on the positioning rod 3, so that the self-rotating gear 53 During the revolution, the movable rod 52 can be driven to rotate, and the rotation of the movable rod 52 further drives the crushing knife 59 to rotate, which undoubtedly enhances the crushing effect of the crushing knife 59 on the tea leaves. The rotation of the crushing knife 59 increases its cutting speed and cutting frequency, so that each cut can penetrate the tea leaves more effectively, thereby reducing the total time and energy required for crushing and improving the overall crushing efficiency. The composite motion of rotation and revolution makes the cutting path of the crushing knife 59 more complex and changeable, which can more effectively crush the hard parts and irregular shapes of the tea leaves, reduce the residue of large pieces, and improve the uniformity and fineness of the crushed tea leaves. When the gear ring 51 and the movable rod 52 rotate, the guide rod 511 can move up and down with the reciprocating block 512. Such movement, in conjunction with the elastic force of the first damping spring 510, can drive the spline rod 54, the rectangular rod 55 and the gear rod 56 to move up and down, so that the gear rod 56 can drive the half gear 58 and the crushing knife 59 to reciprocate during the up and down movement, thereby adjusting the crushing angle of the crushing knife 59 on the tea leaves. By adjusting the crushing angle of the crushing knife 59, we can more effectively crush the tea leaves according to their shape and hardness, reduce ineffective crushing time, and improve the overall crushing efficiency. The cutting of the crushing knife 59 at different angles can more comprehensively cover all parts of the tea leaves, ensure the uniformity of crushing, reduce the residue of large pieces, and improve the uniformity of the crushed tea leaves. The rotating shaft can drive the driving rod 4 to rotate synchronously through the second synchronous belt pulley transmission member 517. The rotation of the driving rod 4 drives the first spiral blade 519 to rotate synchronously, thereby driving the tea leaves inside the barrel 63 to enter the fixed tube 518, realize upward transportation, and be discharged through the discharge pipe 520. In this way, the crushing knife 59 crushes the tea leaves again. During the transportation process, the tea leaves are not only smoothly transferred from the barrel 63 to the subsequent processing area, but also undergo additional crushing. This continuous crushing process ensures that the tea leaves are fully and evenly crushed before reaching the final product form, thereby improving the efficiency and quality of the crushing. The rotation of the first spiral blade 519 not only promotes the transportation of the tea leaves, but also performs preliminary mixing and dispersion of the tea leaves to a certain extent, which helps to improve the fluidity of the tea leaves during the crushing process and reduce the risk of blockage and accumulation.

[0021] Embodiment 2: Combination Figure 7 As shown, on the basis of the second embodiment, two support frames 21 are firmly installed around the inside of the material box 2. The two support frames 21 play a role in stabilizing the structure. A reciprocating screw 22 is installed on the upper end of the support frame 21. The reciprocating screw 22 can realize the reciprocating movement of the moving rod 24 up and down. A set of mechanisms for transmitting power through a first synchronous belt pulley transmission member 23 is installed on the top of the reciprocating screw 22. This first synchronous belt pulley transmission member 23 is tightly connected to the driving rod 4, thereby realizing the transmission of driving force. The bottom of the reciprocating screw 22 is designed with a thread, which can be connected to the threaded interface of the moving rod 24, so that the moving rod 24 can rise or fall along the thread under the drive of the reciprocating screw 22; The moving rod 24 is designed along the vertical direction of the support frame 21 and can slide freely on its surface. The bottom of the moving rod 24 is connected to the cover plate 26 by a connecting rod 25, so that the cover plate 26 can rotate around the bottom of the material box 2. This rotating installation method of the cover plate 26 makes it more convenient to open and close. On the outside of the moving rod 24, a row of toggle rods 27 are provided. These toggle rods 27 can be used to control the switch of the cover plate 26, and can also be used for the operation of other functions. The design of the entire mechanism not only ensures the convenience of operation, but also improves work efficiency.

[0022] In the embodiment of the present invention, during the rotation of the driving rod 4, the reciprocating screw rod 22 can realize synchronous rotation by means of the first synchronous belt pulley transmission member 23. This process ensures that the reciprocating screw rod 22 can effectively push the moving rod 24 to move up and down on the support frame 21 while rotating. When the moving rod 24 moves up and down, the cover plate 26 can be opened and closed at the bottom of the material box 2 by cooperating with the connecting rod 25. This process is very important for the intermittent transportation and crushing of tea leaves inside the material box 2. By intermittently conveying the tea leaves into the cylinder 1 for crushing, not only can the crusher maintain a high working efficiency, but also problems such as poor crushing effect or equipment overload caused by too much or too little tea leaves can be avoided. In addition, the function of the toggle rod 27 is to disperse the tea leaves inside the material box 2 to prevent excessive accumulation of tea leaves, or even the embarrassing situation of being unable to discharge the material.

[0023] Example 3: Combination Figure 8 As shown, on the basis of the third embodiment, the discharge assembly 6 is composed of a discharge pipe 61 fixedly mounted on the bottom of the barrel 1, and a second spiral blade 62 fixed on the driving rod 4 is arranged inside the discharge pipe 61, and the thread direction of the second spiral blade 62 is opposite to that of the first spiral blade 519. The function of the first spiral blade 519 is to drive the broken tea leaves to be transported upward, while the second spiral blade 62 is responsible for transporting the broken tea leaves downward. The barrel 63 is fixedly connected to the upper end of the discharge pipe 61, and its position is below the fixed pipe 518, and its shape is semicircular. At the top of the inner cavity of the discharge pipe 61, there is a sealing cover 64 for sealing the discharge pipe 61, and the sealing cover 64 is sealingly slidably mounted on the driving rod 4; A second damping spring 65 is fixedly connected to both sides of the top of the sealing cover 64, and the top of the second damping spring 65 is fixedly connected to the bottom of the fixed tube 518. Trapezoidal blocks 66 are fixedly connected to both sides of the bottom of the sealing cover 64. A cylinder 67 fixedly mounted on the inner wall of the cylinder 1 is provided on one side of the trapezoidal blocks 66. A moving wheel 68 that slides in contact with the side wall of the trapezoidal block 66 is provided at the output end of the cylinder 67. This design allows the discharge assembly 6 to operate more smoothly during operation, thereby improving the efficiency of crushing tea leaves.

[0024] In the embodiment of the present invention, with the help of the elastic force of the second damping spring 65, the sealing cover 64 moves in the downward direction, thereby sealing the top of the discharge pipe 61. At the same time, the tooth rod 56 crushes the tea leaves, and the crushed tea leaves then enter the barrel 63. Inside the barrel 63, the tea leaves are transported upward through the first spiral blades 519 in the fixed pipe 518. After the tea leaves are crushed, the cylinder 67 is turned on to drive the moving wheel 68 to move toward the inside of the discharge pipe 61. In this way, the moving wheel 68 can push the trapezoidal block 66 to move upward, thereby pushing the sealing cover 64 to move upward. , and at the same time compress the second damping spring 65, so that the crushed tea leaves in the barrel 63 can enter the discharge pipe 61 and are discharged through the second spiral blade 62. When the crushed tea leaves in the barrel 63 are discharged, the cylinder 67 is opened to drive the moving wheel 68 to move outward. Under the elastic force of the second damping spring 65, the sealing cover 64 and the trapezoidal block 66 move downward and reset, so that the sealing cover 64 re-seals the discharge pipe 61. In this way, the cylinder 1 can crush the tea leaves again, and the whole process is cyclically carried out to ensure the continuity and efficiency of the tea crushing work.
