Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery testing, and particularly to a portable reliability test device for tea pickers. Background Art

[0002] Currently, there is no reliability test equipment on the market that can meet the requirements of the "Tea Picker" identification outline DG / T - 076 - 2019, where the cumulative operating time of the tea picker is not less than 18 hours. Yuan Xiaoliang proposed a reliability test platform for the cutter of a small harvester in the article "Research on the Reliability Test Platform for the Cutter of a Small Harvester" in the Chinese Journal of Agricultural Mechanization. This method uses the rotation of a spiral auger to throw materials towards the cutter, as Figure 1 shown. However, this method cuts by throwing materials, which has uncertainties in cutting, such as empty cutting, inaccurate cutting, and uneven cutting. Moreover, there are only four spiral augers, meaning that only four points of the cutter are cutting simultaneously, and the cutter blades are not fully covered, so it is not suitable for the reliability test of tea pickers.

[0003] Operation limitations of the prior art: 1. The existing design of tea pickers mainly focuses on improving the picking efficiency and tea quality, while ignoring the reliability test of the tea pickers themselves. 2. The reliability test standard of tea pickers requires the equipment to be able to operate continuously for more than 18 hours. However, in actual applications, due to the limitation of the tea growth cycle, the quantity of on - site tea is often insufficient to support such a long - time continuous operation. Because after the tea is cut, it needs to wait for it to grow again. The existing tea pickers lack special reliability test devices, it is difficult to find enough tea for long - time continuous operation tests, and it is impossible to simulate the actual operation environment for long - time tests, and it is impossible to simulate the actual process of the tea picker cutting tea, which limits the comprehensive evaluation and optimization of the performance of tea pickers. Need alternative materials for continuous testing: In order to overcome the limitation of the quantity of tea, it is necessary to find an alternative material with similar stem traits to tea so that the tea picker can perform continuous cutting operations, thereby completing the required 18 - hour reliability test. Due to the lack of long - time continuous operation tests, it is impossible to comprehensively evaluate the performance and reliability of the tea picker in a long - time working state. And the tea picker may malfunction due to undetected design defects or material fatigue during actual use, affecting the picking efficiency and tea quality. Summary of the Invention

[0004] The purpose of the present invention is to propose a portable reliability test device for tea pickers in view of the deficiencies of the prior art, which can provide an effective solution for the reliability test of tea pickers by simulating the actual process of cutting tea.

[0005] The object of the present invention is achieved by the following technical solutions: A reliability test device for a portable tea picking machine, and the specific solution is as follows: The device includes a feeding mechanism and a moving mechanism;

[0006] The feeding mechanism includes rollers, a right box body, a left box body, pins and a storage tray;

[0007] A groove is left relatively between the right box body and the left box body, and two adjacent rollers are detachably installed above the two box bodies; The storage tray is used to roll in tea materials, and is sleeved on the pins, and is integrally installed in the groove between the right box body and the left box body, and the tea materials are inserted into the gaps between adjacent rollers;

[0008] The moving mechanism includes a lifting platform, a bearing plate, guide rails and sliders;

[0009] The bearing plate is slidably connected above the right box body and the left box body, and a lifting platform is installed on the bearing plate, and the lifting platform is connected to the tea picking machine.

[0010] Further, the feeding mechanism includes a feeding motor; The feeding motor is connected to the rollers through gear meshing, so as to realize the rotation of two adjacent rollers with the same speed but different directions, and use static friction to convey the tea materials to the tea picking machine.

[0011] Further, the feeding mechanism includes casters; The casters are installed below the right box body and the left box body, and are used for the overall movement and fixation of the two box bodies.

[0012] Further, the tea picking machine is fixed on the lifting platform through elastic straps and G-type tool clamps.

[0013] Further, a slider is fixed below the bearing plate to form an integral slider, and guide rails are fixed above the right box body and the left box body, and the integral slider is slidably connected with the guide rails.

[0014] Further, the moving mechanism further includes a moving motor, a crank and a connecting rod, and the crank, the connecting rod, the integral slider and the guide rails form a crank-slider mechanism; The moving motor is connected to the integral slider through the crank and the connecting rod.

[0015] Further, when the crank rotates to the limit position, the tea picking machine cuts the tea for collection; When the crank rotates to the other limit position, the tea picking machine moves away from the tea, and the rollers rotate to supply new tea for the tea picking machine to cut.

[0016] Further, the tea material is replaced by a PTFE capillary tube with an outer diameter of 2.9 mm and an inner diameter of 2.5 mm, and is rolled into the storage tray by winding, and the material is lifted by the reverse rotation of the rollers to simulate the growth process of "tea leaves".

[0017] Further, the clearance distance between the outer diameters of two adjacent rollers is less than the diameter of the tea material, and static friction is generated by extrusion to convey the material upward.

[0018] Further, the roller diameter, the gear transmission train, and the rotational speed of the feeding motor are designed according to the requirements of the final feeding speed. When the cumulative operating time reaches [X] hours, the feeding economic cost is reduced.

[0019] Through the design of the technical solution of the present invention above, the present invention has the following technical characteristics:

[0020] 1. Simulating the mechanism of tea reciprocating growth: The present invention realizes the mechanism of simulating the reciprocating growth of tea by inserting multiple rolls of materials into the component pin. This design allows the tea picking machine to conduct long-term continuous operation tests without real tea. By rotating the rollers at the same speed but in opposite directions, the materials are driven to rise, simulating the growth process of tea, so as to realize the continuous cutting test of the tea picking machine.

[0021] 2. Recycling of materials: Since real tea in reality is non-renewable and non-recyclable for cutting, the method of the present invention uses alternative materials. By selecting materials with similar characteristics to thin hoses and winding them around the feeding mechanism of the present invention, and rotating the rollers in the reverse direction to make the materials rise, simulating the growth process of "tea", a large number of tests on the reliability of the tea picking machine are realized. This method not only reduces the large cost consumed by cutting real tea, but also solves the problem of lack of tea in the subsequent reliability tests of the tea picking machine.

[0022] 3. Design limit of the knife edge distance: To ensure the stability during the cutting process, the present invention specifically designs the distance limit between the "tea" and the knife edge of the tea picking machine to be approximately 3 cm. Multiple groups of gears are used to drive the component rollers and the component motor, reducing the longitudinal distance A between the component lifting table surface and the component rollers; in addition, only gear transmission is used instead of belt transmission, reducing the lateral distance B, as Figure 10 shown. This design makes the discharge port of the component roller extremely close to the blade, and effectively reduces the extension of the length C of the component lifting table surface, ensuring the stability and reliability during the simulated cutting process, and at the same time simulating the relative position between the tea and the blade in the actual tea picking process.

[0023] 4. Tea picking machines applicable to different blade sizes: Since the roller and the gear shaft are connected and matched by keys, as Figure 12 and Figure 13 shown, which is a non-permanent connection and the roller is detachable, it can adapt to the blade sizes of different tea picking machines. By moving the two side boxes, as Figure 14 shown, the size of the component roller can be freely customized to ensure the reliability test of tea picking machines with different total blade lengths.

[0024] 5. The tea picking machine moving mechanism of the device adopts an innovation of a crank-slider. By punching a groove in the base on the slider and placing a lifting table on the groove, the tea picking machine can freely slide left and right and move up and down. The feeding mechanism of the device drives the material on the component pin through the rotation of the roller, and rotates the pre-placed batch of "tea leaves". Through calculation, it can meet the feeding requirement of "Tea Picking Machine DG-T076-2019" for 18 hours continuously. The moving mechanism of the tea picking machine is combined with the feeding mechanism to simulate the real tea picking process of the tea picking machine, and the "tea leaves" are extremely close to the cutting edge of the tea picking machine, and the cutting process is continuous and stable.

[0025] Based on the technical characteristics of the present invention, the beneficial effects of the present invention are as follows:

[0026] 1. The present invention designs a portable tea picking machine reliability test device. This device can use substitute materials to simulate tea stems, and the feeding system should at least feed for 18 hours continuously, enabling the tea picking machine to conduct long-term continuous operation tests without being restricted by the quantity of tea leaves. And during the operation process, it simulates the real process of the tea picking machine cutting tea leaves, thereby improving the overall performance and service life of the tea picking machine.

[0027] 2. The present invention uses substitute materials similar to the traits of tea stems, pre-winds them into the storage tray of component 8, and then successively sleeves the storage tray of component 8 onto the pin of component 7 for testing. The advantage is that it reduces the dependence on real tea leaves, lowers the test cost, and at the same time avoids test interruptions caused by the tea leaf growth cycle. The mechanical device of the present invention can simulate the actual process of cutting tea leaves, thereby conducting continuous reliability tests on the tea picking machine.

[0028] 3. The present invention simulates the mechanism of the reciprocating growth of tea leaves: the rotation of the rollers with the same speed and opposite directions drives the material to rise, simulating the growth process of tea leaves. The advantage is that it realizes long-term continuous operation tests of the tea picking machine, improves the efficiency and reliability of the tests. By adjusting the motor speed of the feeding mechanism, the quantity of materials required for a single tea picking machine reliability test and the length of the materials cut by the tea picking machine each time can be artificially controlled, realizing more accurate tea picking machine reliability tests.

[0029] 4. The precise design of the distance between the cutting edges of the present invention: The designed limit of the distance between the "tea leaves" and the cutting edge of the tea picking machine is 3 cm. The advantage is that it ensures the stability during the cutting process, simulates the relative position of the tea leaves and the blade during the actual tea picking process, and improves the authenticity of the test results.

[0030] 5. The present invention simulates the process of a tea picking machine cutting tea leaves: by adjusting the motor speed of the moving mechanism of the tea picking machine, the translation speed of the tea picking machine can be adjusted. An appropriate speed can adjust the speed of the tea picking machine to be close to the walking speed of a person, thereby simulating the process of a real person holding a tea picking machine to move and pick tea, and realizing a more accurate reliability test of the tea picking machine.

[0031] 6. The present invention provides a device for reliability test that can be used by technology institutions for promoting and appraising tea picking machines, tea picking machine manufacturing enterprises, etc. It meets the requirements of the appraisal outline for the reliability test of tea picking machines and enhances the market competitiveness of products. At present, there is no ready-made portable mechanical device for the reliability test of tea picking machines on the market. The proposal of the present invention is precisely to fill this gap and meet the industry's demand for the reliability assessment of tea picking machines. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described below in conjunction with the accompanying drawings and implementation cases. It should be understood that the specific implementation cases described herein are only used to explain the present invention and are not used to limit the present invention.

[0057] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 10 shown, a reliability test device for a portable tea picking machine provided by the present invention mainly consists of two key parts, including a feeding mechanism and a moving mechanism, aiming to simulate the operation process in actual tea picking work. The feeding mechanism is composed of component roller 2, right box body 3, feeding motor 4, caster 5, left box body 6, pin 7, and storage tray 8. First, the tea materials are pre-rolled into component storage tray 8, then component storage tray 8 is successively sleeved on component pin 7, and the whole is placed in the grooves of component right box body 3 and component left box body 6. The tea materials in the storage tray are successively inserted into the gaps between component rollers 2 to complete the reserve work of the tea materials. In addition, component caster 5 can play the role of overall movement and fixation of component left box body 3 and component right box body 6. Secondly, the feeding mechanism is connected with component roller 2 and component feeding motor 4 through gear meshing to realize the reverse rotation of component roller 2 (the same speed but opposite directions), and the tea materials are conveyed upward by using static friction to ensure a stable and continuous feeding process. This design can not only effectively convey the tea materials upward, but also provide an efficient feeding function while keeping the operation simple. The moving mechanism is composed of component lifting platform 1, bearing plate 9, moving motor 10, crank 11, connecting rod 12, guide rail 13, and slider 14. First, component lifting platform 1 is fixed on component bearing plate 9 through bolt connection, and the portable tea picking machine is fixed on component lifting platform 1 through elastic straps and G-type tool clamps to realize the fixation of the overall position of the portable tea picking machine on component bearing plate 9. Component bearing plate 9 and component slider 14 are connected by bolts to form an "overall slider", and component crank 11, component connecting rod 12, component guide rail 13 and the "overall slider" form a crank-slider mechanism. Driven by component moving motor 10, during the rotation of component crank 11, the reciprocating movement of the portable tea picking machine on component guide rail 13 can be realized. The overall design focuses on simulating the working conditions in the real environment, and through precise mechanical structures and appropriate fixing methods, the accuracy and reliability of the test results are ensured.

[0058] 1. Design of the feeding mechanism

[0059] According to the research of Journal of Zhejiang University (Agriculture & Life Sciences), "Research on the Shearing Mechanical Properties of Tea Shoots", the tea density is generally 2000 - 3500 plants / m 2 , and the number of tea plants in the cutting area is calculated according to the following formula.

[0060] n = ρ·s = (2000 - 3500) * 0.014 = 28 - 49

[0061] Where: n is the number of tea plants in the cutting area; ρ is the tea density; s is the cutting area.

[0062] During the actual cutting process, the number of tea leaves on the blades of the tea picking machine is generally 28 - 49 plants. The average value is selected as the number of samples for the simultaneous cutting of the blades in the reliability test of the tea picking machine. That is, 38 sets of tea substitute materials are sleeved into the pin 7 (the number of samples can be reduced or increased correspondingly by comprehensively considering the requirements of the reliability test and the economic cost), as Figure 6 and Figure 7 shown. Finally, the whole is placed in the notch of the mechanical device, as Figure 8 shown.

[0063] The tea substitute material (such as a PTFE capillary with an outer diameter of 2.9 mm and an inner diameter of 2.5 mm) is conveyed upward by the outer meshing of the roller 2. The roller 2 is connected to the gear by a key for transmission. The power source is the feeding motor 4, that is, a shaft-mounted gear reduction motor, which is transmitted through the gear. All gears have the same modulus and number of teeth, and only play the role of lifting the roller 2. Because the gears have the same modulus and number of teeth, the gears connected to the roller 2 rotate at the same speed and in opposite directions, realizing the same-speed reverse outward rolling of the roller 2. The clearance distance between the outer diameters of the roller 2 is less than the diameter of the tea substitute material, and static friction is generated by extrusion to convey the material upward.

[0064] Initially, the distance between the roller 2 and the cutting edge of the tea picking machine blade is about 17 cm, as Figure 9 shown. After the design improvement of the gear transmission, the longitudinal distance A and the lateral distance B between the tabletop of the component lifting platform 1 and the component roller 2 are compressed, and the extension of the length C of the tabletop of the component lifting platform 1 is effectively reduced, as Figure 10 shown. This design makes the component roller 2 extremely close to the blade. The distance between the roller 2 and the cutting edge of the tea picking machine blade is about 3 cm, as Figure 11 shown. It ensures the stability of the conveying of the tea substitute material and the cutting material of the tea picking machine.

[0065] Because the roller 2 and the gear shaft are connected and matched by a key, which is a non-permanent connection, the roller 2 is detachable, as Figure 12 and Figure 13 shown. By moving the right box body 3 and the left box body 6, as Figure 14 shown, the size of the roller 2 can be freely customized to ensure the reliability test of tea picking machines with different total blade lengths.

[0066] The power source of the roller 2 is the feeding motor 4, which is a shaft-mounted gear reduction motor with an average speed of about 5 RPM. According to the reliability evaluation of "DG-T076-2019 Tea Picking Machine", the calculation of the effectiveness K of the tea picking machine requires that the prototype has a cumulative operation time of not less than 18 h. If the cutting consumable speed of the tea picking machine is slower, the consumption quantity of the tea substitute is less and the cost is lower. Therefore, under the condition of reasonable speed, the cutting material speed of the tea picking machine should be reduced as much as possible. In fact, the consumption speed of the cutting material of the tea picking machine does not depend on the tea picking machine itself, but on the rotation speed of the roller 2. The slower the rotation speed of the roller 2, the slower the conveying of the tea substitute material, and the slower the consumption speed of the cutting material of the tea picking machine, achieving the purpose of reducing material consumption and cost. If a motor with a speed of 5 RPM is selected and the diameter of the roller 2 is 66 mm, and a gear train with a transmission ratio of 1 is constructed, as Figure 10 shown, the feeding speed is about 17 mm / s. When the cumulative operation time is 18 h, each tea substitute material consumes about 1100 m; if through gear reduction cooperation, the diameter of the roller 2 remains unchanged, the speed of the power source motor is changed to about 36 RPM, and a gear train with a transmission ratio of 128 is constructed, as shown in Figure 15, the feeding speed can be reduced to 1 mm / s. When the cumulative operation time is 18 h, each tea substitute material consumes about 65 m. Therefore, the gear train inside the box 3 and the motor speed design can be adjusted according to the requirement of the final feeding speed, that is, the requirement of the feeding economic cost.

[0067] 2. Design of the reciprocating movement mechanism of the tea picking machine

[0068] 2.1 Fixing of the tea picking machine

[0069] The lifting table 1 and the bearing plate 9 are cooperated by bolt connection. When the bolts are loosened, the lifting table 1 can move along the chute in the bearing plate 9 to realize the free movement of the lifting table 1 of the tea picking machine. The bearing plate 9 is as Figure 16 shown. When the lifting table 1 moves to a suitable position, tighten the bolts to fix the lifting table 1 and the bearing plate 9. As Figure 17 shown.

[0070] After the lifting table 1 moves to a suitable position and is adjusted to a suitable height, then place the tea picking machine on the lifting table 1 and fix the tea picking machine on the lifting table 1 through elastic straps and G-type tool clamps. As Figure 18 and Figure 19 shown.

[0071] 2.2 Cutting of the tea picking machine

[0072] The moving and cutting motion of the tea plucking machine is realized through a crank-slider mechanism. The portable tea plucking machine and the lifting table 1 are integrally fixed on the bearing plate 9. The bearing plate 9 and the slider 14 are connected by bolts to form an "integral slider". The crank 11, the connecting rod 12, the guide rail 13 and the "integral slider" form a crank-slider mechanism. Driven by the moving motor 10, during the rotation of the crank 11, the reciprocating movement of the portable tea plucking machine on the guide rail 13 can be realized. The moving motor 10 selects a horizontal gear reduction motor as the power source, and the average rotational speed is about 30 RPM. The crank-slider mechanism is as Figure 20 shown.

[0073] When the crank 11 rotates to the extreme position, the tea plucking machine cuts the tea, and the cut part is blown into the material collection bag by the air outlet of the tea plucking machine itself, as Figure 21 shown.

[0074] When the crank 11 rotates to the other extreme position, the tea plucking machine moves away from the tea. While the crank 11 rotates, the roller 2 slowly rotates to supply new tea for the tea plucking machine to cut, as Figure 22 shown.

[0075] The above embodiments are used to explain the present invention, rather than limit the present invention. Any modification and change made to the present invention within the spirit and scope of the claims of the present invention fall within the protection scope of the present invention.
