[0002] As an important agricultural product, tea has very high quality requirements in its production process. Tea fresh leaves, as the raw material for tea production, directly affect the taste and quality of the final tea product. Therefore, it is crucial to accurately and efficiently sort tea fresh leaves during tea production.

[0003] The existing tea screening device mainly uses a sieve plate for screening work. The sieve plate is driven to vibrate reciprocally to achieve screening. The sieve plate screens tea mainly by utilizing the physical properties of the sieve plate. The size and shape of the sieve holes are used to screen tea. Tea rolls and jumps on the sieve plate. Smaller tea particles and impurities fall through the sieve holes, while larger tea particles remain on the sieve plate, thereby achieving the purpose of grading and screening. It usually includes the following parts: sieve plate: composed of sieve nets with different hole diameters, used for grading and screening tea. Driving device: provides power to enable the sieve plate to vibrate or rotate continuously and stably, thereby achieving tea screening. Feeding device: uniformly and continuously feeds tea into the sieve plate for screening. Discharge device: collects screened tea for subsequent processing.

[0004] However, the tea on the sieve plate is in a stacked state, which reduces the screening efficiency. The stacked tea is prone to overlap, making it difficult to separate the tea particles.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Please refer to Figures 1-6The utility model provides a kind of tea fresh leaf sorting device technical scheme with good screening effect: a kind of tea fresh leaf sorting device with good screening effect, comprising: cylinder 1, cylinder 1 one end is provided with feed inlet 2, cylinder 1 bottom is provided with through 4, both ends of cylinder 1 bottom are fixedly installed with support foot 5, through 4 is provided with filter plate 6, filter plate 6 and the shape matching of through 4, filter plate 6 inboard camber is consistent with the inboard camber of cylinder 1.Cylinder 1 is provided with mounting mechanism, and mounting mechanism is connected with filter plate 6, and filter plate 6 is installed on cylinder 1 by mounting mechanism, and a plurality of turnover plates 7 are arranged in cylinder 1, and a plurality of turnover plates 7 are distributed in the circumferential array of cylinder 1, and one end in cylinder 1 is provided with connecting frame 8, and connecting frame 8 is fixedly connected with a plurality of turnover plates 7, and motor 9 is fixedly installed outside cylinder 1, and the output shaft of motor 9 is fixedly connected with connecting frame 8, and the output shaft of motor 9 is collinear with the central axis of cylinder 1, and a plurality of ventilation openings 3 are formed in the other end of cylinder 1, and ventilation mechanism is installed outside cylinder 1, and ventilation mechanism is used to guide airflow into ventilation opening 3, and storage groove 10 is placed in the lower end of filter plate 6, and storage groove 10 is located between two support feet 5.

[0025] Tea is placed into cylinder 1 by feed inlet 2, and filter plate 6 is in the state of blocking through 4 under normal circumstances, and tea is filtered by setting filter plate 6, and smaller tea can pass through the filter hole on filter plate 6, while larger tea remains in cylinder 1, and smaller tea passes through filter plate 6 and falls into storage groove 10, and screened tea is collected by storage groove 10.In the screening process, connecting frame 8 is driven to rotate by starting motor 9, and a plurality of turnover plates 7 on connecting frame 8 rotate synchronously, and turnover plate 7 can drive tea in cylinder 1 to move upward, and tea can slide out of turnover plate 7 and fall again in cylinder 1 when tea moves to high place, so that tea is continuously stirred and tossed in the screening process, avoiding tea in the state of accumulation, and by continuously stirring and tossing tea, tea can be effectively prevented from accumulating and blocking on screen, so that tea particles can pass through filter hole more smoothly, thereby improving screening efficiency.Meanwhile, stirring and tossing operation helps tea to be evenly distributed on screen, avoiding uneven screening caused by local accumulation, to ensure that tea can be evenly subjected to screening treatment.

[0026] Two support feet 5 are provided with shock-absorbing pads at the bottom to reduce vibration during operation. The cylinder 1 is provided with an inverted slope at the inlet 2, and the inverted slope is distributed on the inner side of the cylinder 1. By setting the inverted slope, the tea in the cylinder 1 is not easy to fall out of the inlet 2. The mounting mechanism includes two U-shaped frames 11 arranged at intervals, the two ends of the U-shaped frame 11 penetrate the filter plate 6, the upper end of the U-shaped frame 11 is fixedly connected to the cylinder 1, and the lower end of the U-shaped frame 11 is fixedly connected with two elastic members 12 arranged at intervals, and the upper end of the elastic member 12 is fixedly connected to the filter plate 6. After the screening is completed, the residual tea in the cylinder 1 needs to be taken out. If it is directly taken out from the inlet 2, there is a problem of inconvenient operation. The filter plate 6 can be pressed to make the filter plate 6 move downward and the elastic member 12 be compressed, and then the filter plate 6 is completely separated from the opening 4, and the residual tea in the cylinder 1 can be directly dropped from the opening 4, which can improve the efficiency of discharging the residual tea in the cylinder 1.

[0027] Because the amount of tea in the cylinder 1 is large, the tea is in a stacked state, and the internal space of the cylinder 1 is relatively closed, which makes the tea inside easy to heat, which can damage the quality of the tea.

By setting the fan 14 to blow low-temperature airflow into the ventilation opening 3, and then into the cylinder 1, the heat dissipation of the tea in the cylinder 1 is accelerated, and the tea is prevented from being burned out. At the same time, the airflow passes through the tea in the turning process, which can blow away the dust on the tea, and the airflow containing dust is discharged from the inlet 2 of the cylinder 1, which can play a dust removal role.

[0028] The working principle of the utility model is: tea is put into the cylinder 1 through the feeding port 2, the filter plate 6 is in the state of blocking the through port 4 under normal condition, tea is filtered through setting the filter plate 6, smaller tea can pass through the filter hole on the filter plate 6, while larger tea stays in the cylinder 1, smaller tea passes through the filter plate 6 and falls into the storage groove 10, the sieved tea is collected through the storage groove 10. In the sieving process, the motor 9 drives the connecting frame 8 to rotate, the multiple turnover plates 7 on the connecting frame 8 rotate synchronously, the turnover plate 7 can drive the tea in the cylinder 1 to move upwards, when the tea moves to a high place, the tea can slide out of the turnover plate 7 and fall into the cylinder 1 again, so that the tea is continuously turned and tossed in the sieving process, avoiding the tea in the accumulation state, through continuously turning and tossing the tea, the accumulation and blockage of the tea on the sieve plate can be effectively reduced, the tea particles can pass through the sieve hole more smoothly, so as to improve the sieving efficiency. At the same time, the turnover operation is helpful for the uniform distribution of the tea on the sieve plate, avoiding the uneven sieving problem caused by local accumulation, ensuring that the tea can be uniformly subjected to the sieving treatment.

[0029] The above is only the preferred embodiment of the utility model, it should be pointed out that, for the ordinary skilled person in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, these improvements and refinements should also be regarded as the protection scope of the utility model.
