[0002] Tea, commonly known as tea, generally includes the leaves and buds of tea trees. It is a brewed beverage. When obtaining it, tea farmers need to collect it from tea trees. However, this traditional way of picking tea leaves has a low speed of picking tea leaves. In order to improve the efficiency of picking tea leaves, tea picking machines are generally used for picking tea leaves. However, when using tea picking machines, it is easy to mix many tree sticks with the tea leaves and collect them together. Such tree sticks need to be separated from the tea leaves in time to avoid affecting the brewing taste of the tea leaves. In view of this, we propose a tea production impurity removal device.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Reference Figure 1-Figure 6 A tea production impurity removal device comprises an impurity removal box 1 and an impurity removal chamber 4 arranged inside the impurity removal box 1. A feed hopper 2 connected to the impurity removal chamber 4 is arranged on the upper part of the impurity removal box 1, and a carrying plate 5 is arranged at the bottom of the impurity removal chamber 4. An impurity removal mechanism 3 for cleaning impurities in the tea leaves is arranged in the impurity removal box 1. Freshly collected tea leaves contain some impurities such as tea stalks and tea seeds, which will affect the quality and taste of the tea leaves. These impurities can be removed by impurity removal, thereby improving the quality and taste of the tea leaves. When the device is used, the tea leaves are first put into the impurity removal chamber 4 from the feed hopper 2, and then the tea leaves on the carrying plate 5 are cleared by the impurity removal mechanism 3, thereby realizing the removal of impurities in the tea leaves.

[0025] The impurity removing mechanism 3 includes a plurality of vibrating rods 31 rotatably mounted on the bottom of the impurity removing box 1, a synchronous sprocket group 33 is installed between the vibrating rods 31 for transmission, an impact wheel 32 for contacting with the carrying plate 5 is fixedly sleeved on the vibrating rod 31, a purge assembly 34 is provided on the inner wall of the impurity removing chamber 4 and close to the feed hopper 2, and a driving assembly 35 for controlling the operation of the vibrating rod 31 and the purge assembly 34 is provided outside the impurity removing box 1. During impurity removal, the movement of the purge assembly 34 and the vibrating rod 31 can be controlled by the driving assembly 35. Since the position of the purge assembly 34 is close to the feed hopper 2, the tea leaves just entering the impurity removing chamber 4 from the feed hopper 2 will be affected by a parallel wind, causing the tea leaves and their impurities to be horizontally projected. Since the density of tea leaves is relatively small, while the density of tea stems, tree sticks and other impurities is relatively large, the lateral displacement of tea leaves is far greater than that of tree sticks and other impurities. At the same time, the rotation of the vibrating rod 31 will drive the impact wheel 32 to continuously impact the bottom of the carrying plate 5, causing the carrying plate 5 to continuously vibrate. Figure 2 As shown, the carrying plate 5 and the impurity removal box 1 are both arranged at an angle. Under the continuous vibration of the carrying plate 5, the tea leaves and impurities will be gradually separated, thereby achieving the impurity removal operation of the tea leaves.

[0026] The purge assembly 34 includes an air induction chamber 341 opened on one side of the impurity removal box 1, the air induction chamber 341 is connected with the impurity removal chamber 4 and the outside respectively, and a filter 343 is installed at the connection point, and a purge blade 342 is provided in the air induction chamber 341. When the purge blade 342 rotates, it will introduce the external airflow into the impurity removal chamber 4 to form a horizontal purge airflow, which promotes the separation of tea leaves and impurities. The setting of the filter 343 can effectively prevent external impurities from entering the impurity removal chamber 4 to contaminate the tea leaves.

[0027] The driving assembly 35 includes a driving motor 351 fixedly mounted on the outside of the impurity removal box 1. A driving sprocket group 352 is provided at the output end of the driving motor 351. The driving motor 351 is transmission-connected to the blowing blade 342 via the driving sprocket group 352. When the device is in use, the driving motor 351 can be started to drive the blowing blade 342 to rotate, thereby achieving the blowing of tea leaves and enhancing the separation rate of impurities.

[0028] A driving gear 1 353 connected to the driving sprocket set 352 is rotatably installed at the bottom of the debris removal box 1, and a driving gear 2 354 rotatably connected to the debris removal box 1 is meshed with the outside of the driving gear 1 353. A driving sleeve 355 coaxially fixed to the vibration rod 31 is rotatably installed at the lower part of the debris removal box 1. The driving sleeve 355 is provided with driving teeth meshing with the driving gear 2 354. When the driving motor 351 is running, the driving gear 1 353 is driven to rotate through the driving sprocket set 352, and the driving gear 1 353 drives the driving sleeve 355 to rotate by meshing with the driving gear 2 354. 55 rotates. Since the driving sleeve 355 is coaxially fixed with the vibration rod 31, when the driving sleeve 355 rotates, the vibration rod 31 will be driven to rotate synchronously. At the same time, since a synchronous sprocket set 33 is provided between the vibration rods 31, all the vibration rods 31 will also rotate synchronously. In addition, due to the setting of the number of teeth in the driving gear 1 353, the driving gear 2 354 and the driving sleeve 355, the output speed of the driving gear 1 353 will be reduced, and its output strength will be increased, thereby enhancing the effect of the impact wheel 32 impacting the supporting plate 5, and improving the impurity removal effect of the tea leaves to a certain extent.

[0029] Embodiment 2

[0030] Reference Figure 1-Figure 6 This embodiment is basically the same as the first embodiment, and is more optimized in that a diverter plate 7 for screening tea leaves and impurities and a drainage chute 8 for discharging tea leaves and impurities from the impurity removal box 1 are provided at the lowest point of the carrying plate 5. Figure 4 As shown, the diverter plate 7 divides the carrier plate 5 into three outlets, wherein the uppermost and smallest drainage chutes 8 are used to discharge tea leaves and impurities respectively, while the middle drainage chute 8 is used to discharge tea leaves still entrained with a small amount of impurities. After discharge, secondary impurity removal can be performed, thereby improving the tea leaves impurity removal effect.

[0031] A temporary retention chamber 6 is provided inside the supporting plate 5, and the lowest end of the temporary retention chamber 6 is connected to the outside world. A plurality of screening holes connected to the temporary retention chamber 6 are provided on the upper part of the supporting plate 5. The collected tea leaves contain not only larger debris such as tree sticks and tea stalks, but also some smaller impurities such as dust and other substances. During the vibration of the supporting plate 5, these impurities will gradually separate from the tea leaves, enter the temporary retention chamber 6 through the screening holes on the supporting plate 5, and be discharged from the bottom of the temporary retention chamber 6 as the supporting plate 5 is vibrated, thereby further improving the tea separation effect.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
