Description
Technical Field
[0001] The utility model relates to the technical field of tea grading, in particular to a tea grading device. Background Art
[0002] During the tea processing, in order to classify tea leaves of different sizes, particle sizes and lengths, a tea grading machine is needed to complete the screening of the tea leaves, so as to achieve a uniform appearance of the tea leaves for subsequent sale and packaging.
[0003] At present, when the existing tea grading machine is in use, in order to ensure the uniform falling of tea leaves, the staff will first place the frame containing tea leaves close to the hopper, manually grab some tea leaves from the frame, and then continuously shake the tea leaves in their hands left and right to perform a dispersion operation to prevent the tea leaves from falling in a fixed position. Since a large amount of tea leaves need to be screened, repeated left and right shaking operations for a long time will cause soreness in the hands of the staff. Therefore, we propose a tea grading device to solve the above problem. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a tea grading device.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-4 A tea grading device comprises a grading machine body 1, a feed hopper 2 is installed above the grading machine body 1, and a guide plate 3 is connected to the inner wall of the feed hopper 2, and the guide plate 3 is set to a V-shaped structure, so that the tea leaves can be smoothly guided. The specific grading principle of the grading machine body 1 is the existing technology, which will not be repeated here. A motor 5 is connected to the lower side of the guide plate 3 through a support plate 4, and a rotating shaft 6 is vertically connected to the output end of the motor 5. A gear 7 is sleeved on the outer side of the rotating shaft 6, and a gear ring 8 is meshed on the side of the gear 7. The gear ring 8 is sleeved on the outer side of a lower barrel 9, and a drop tube 10 is distributed at the bottom of the lower barrel 9. A gear 7 is provided at the center of the guide plate 3 to connect to the lower barrel 9. The groove holes matched with the barrel 9 can make the tea leaves fall smoothly into the lower barrel 9. The support plate 4 can realize the support operation of the motor 5. The motor 5 is a prior art and can drive the rotation of the rotating shaft 6, so that the lower barrel 9 can rotate synchronously. It is particularly noteworthy that the diameter of the drop tube 10 is relatively large, and the drop tube 10 with a larger diameter than the tea leaves to be screened can be designed according to actual production experience, so that the tea leaves can be discharged normally from the drop tube 10. At the same time, the drawings in the specification only show the specific relationship, which is inconsistent with the actual size of the drop tube 10. In actual production, it still needs to be designed according to the actual situation.
[0024] Further, see Figure 2 and Figure 3 It can be known that an annular groove is opened on the inner wall of the slot hole, and a support ring 11 is engaged inside the annular groove. The support ring 11 is sleeved on the outside of the discharge barrel 9. Through the mutual cooperation between the support ring 11 and the annular groove, the stability of the discharge barrel 9 during rotation can be effectively guaranteed.
[0025] Further, see Figure 4 It can be known that the bottom end of the rotating shaft 6 is connected to the support seat 12 through a bearing, and the outer side of the support seat 12 is fixedly connected to the inner wall of the feed hopper 2. When in use, the bottom end of the rotating shaft 6 can be supported by the setting of the support seat 12 to effectively ensure its reliability during rotation.
[0026] Further, see Figure 2 and Figure 3 It can be known that the drop tubes 10 are distributed on the outside of the discharge barrel 9 in a circular array structure, and the drop tubes 10 are all arranged as inclined structures. Multiple groups of drop tubes 10 arranged with inclined structures can achieve a dispersion effect on tea leaves.
[0027] Further, see Figure 2 It can be known that the inner wall of the bottom end of the discharge barrel 9 is connected with an arc block, and the diameter of the arc block is smaller than the discharge barrel 9. Through the setting of the arc block, tea leaves can be piled on the inner wall of the bottom end of the discharge barrel 9. Since the specifications of the arc block are small, the upper opening of the drop tube 10 can be effectively prevented from being blocked, so that the tea leaves can smoothly fall into the upper opening of the drop tube 10 for discharge.
[0028] Further, see Figure 2 and Figure 3 It can be known that the lower side of the guide plate 3 is vertically connected to a fixed plate 15, and the side of the fixed plate 15 is connected to a fixed block 16, and the side of the lower barrel 9 is distributed with an impact block 14. When in use, the impact block 14 and the fixed block 16 are respectively set to rubber material. Through the intermittent collision of the impact block 14 and the fixed block 16, the metal guide plate 3 can resonate to effectively prevent tea from accumulating on the upper surface of the guide plate 3.
[0029] Further, see Figure 3 It can be known that a spring 13 is connected to the side of the impact block 14, and the other end of the spring 13 is fixedly connected to the outer wall of the discharge barrel 9. When in use, through the spring 13 connected to the side of the impact block 14, when the impact block 14 collides with the fixed block 16, the setting of the spring 13 can drive the movement of the position of the impact block 14, so as to provide a certain activity space for the impact block 14, thereby realizing the protection of the impact block 14 and the fixed block 16.
[0030] Working principle: When the utility model is in use, the staff can first place the device at a suitable position, and then start the work of the grading machine body 1. Then the staff can pour the tea leaves that need to be graded into the inside of the feed hopper 2, and the tea leaves are guided by the guide plate 3 inside the feed hopper 2 and fall into the lower barrel 9. At this time, with the continuous driving of the motor 5, the gear 7 can be driven to rotate. Since the gear ring 8 is engaged with it, the lower barrel 9 can be driven to rotate continuously, and the tea leaves in the lower barrel 9 are evenly discharged through the drop pipe 10 to fall into the screen of the grading machine body 1 to achieve the grading of the tea leaves. In addition, during the rotation of the lower barrel 9, the groups of impact blocks 14 connected to the outside by springs 13 can intermittently impact the fixed block 16, thereby transmitting the impact force to the guide plate 3 to vibrate, so as to ensure the smooth fall of the tea leaves above the guide plate 3. The above is the entire working principle of the utility model.
[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
