[0002] During the fermentation and transformation process of white tea, it is very important to improve its quality and optimize its taste. For this purpose, the material is often turned over, also known as turning the pile or turning over. However, in traditional tea turning devices, the material is often turned from one side to the other through a conveying structure, which causes the material to accumulate from one side to the other side, which is not conducive to subsequent withering. As the disclosed prior art: CN213604147U's "A Tea Withering Trough" discloses a tea withering trough, including a trough body, a loading plate and a material guiding mechanism, the trough body is a rectangular hollow structure with an upper opening, and an electric heating plate and a loading plate are arranged inside the trough body; a screw rod is arranged on the upper part of the trough body through a bearing seat, and a material guiding mechanism is arranged on the upper part of the screw rod, the material guiding mechanism includes a base, a telescopic rod, a workbench, a feed hopper, a vibration motor and a disturbance frame, the upper part of the base is connected to the workbench through a telescopic rod, and a rectangular table is arranged on the workbench, a feed hopper is fixedly installed on the rectangular table, and a material guiding trough is arranged at the lower part of the feed hopper; a fixed ear is arranged at the lower part of the workbench, and a disturbance frame is arranged in the middle of the fixed ear. Although the above technology turns the tea leaves through mechanical equipment, since its direction of travel is to move to one side first, it is easy for a pile of tea leaves to be turned and swept to the other side, resulting in a decrease in the subsequent withering effect.

[0003] In order to reduce the above-mentioned situation, the utility model provides a material turning device for withering white tea. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Specifically, Figure 1-Figure 3As shown in the figure, an embodiment of the present utility model provides a material turning device for white tea withering, which includes a withering rack 1. A support cavity 12 is arranged inside the withering rack 1, and a withering cavity 13 is arranged above the support cavity 12. The support cavity 12 is mainly used to support the white tea on the material receiving tray 5 in the withering cavity 13 and provide an effective floating elastic space for it. The withering rack 1 includes a top rack 2 arranged on its top. A downward stirring and material turning component 3 is installed on the top rack 2. The top rack 2 is arranged in a "冂" shape at the upper end of the withering rack 1. The material turning component 3 includes a motor 31 arranged on the top rack 2. The motor 31 is connected to the rotating shaft 32 below. A connecting rod 34 is arranged at the bottom of the rotating shaft 32. A sliding rake 35 is detachably arranged on the connecting rod 34. The sliding rake 35 includes a fitting end (351) in contact with the connecting rod 34. A threaded column 352 is arranged at the top of the fitting end 351. The threaded column 352 is screwed into the inside of the connecting rod 34. A material turning hook 353 is arranged at the downward end of the fitting end 351. It should be noted that for better effect, the adjacent sliding rakes 35 installed on the connecting rod 34 face in opposite directions, realizing both stirring and blocking, reducing the problem of large - range rotation. At the same time, since the upper part is an open opening, the situation of concentrating white tea at a certain place after circumferential rotation will not occur, improving the withering effect. The material turning hook 353 is arranged above the material receiving tray 5 and rotates along the circumference of the material receiving tray 5. A compression spring 51 is arranged at the bottom of the material receiving tray 5. A number of ventilation holes are arranged on the material receiving tray 5. A number of ventilation holes are also arranged on the support plate supporting below the compression spring 51. The ventilation holes on the support plate are arranged staggered with the ventilation holes on the material receiving tray 5. In order to realize the limit of the material receiving tray 5, a guide groove 14 is arranged on the inner wall of the withering rack 1. The material receiving tray 5 moves up and down along the guide groove 14. In addition, one side of the compression spring 51 is installed on the support plate, and the other side abuts against the bottom of the material receiving tray 5 and is respectively connected to the support plate and the material receiving tray 5. When the motor 31 drives the connecting rod 34 to rotate, it also drives the material receiving tray 5 to press down the compression spring 51, and through the resilience of the compression spring 51, the white tea is redistributed, also realizing the effect of material turning;

[0020] See details Figure 1 and 2 To enhance the stability of the rotation of the rotating shaft 32, a reverse L - shaped stirring rod 33 is fixedly connected to the outside of the rotating shaft 32. One end of the stirring rod 33 is connected to the rotating shaft 32, and the other end of the stirring rod 33 is connected to the connecting rod 34. Among them, to realize controllable withering effect, a blower 4 is arranged at the bottom of the withering rack 1. The blowing direction of the blower 4 is from bottom to top, that is, it blows out after entering the withering cavity 13 from the support cavity 12 upward.

[0021] When the utility model is in use, the white tea is spread flat on the receiving tray in the withering rack, and the motor is turned on to drive the rotating shaft and then the connecting rod to rotate. The rotation of the connecting rod drives the sliding rake installed on the connecting rod to rotate, and the white tea on the receiving tray is shifted, so that the white tea is effectively shifted in a circular manner, and the distribution effect is uniform, and the situation that one side is piled on the other side as in the prior art will not occur. At the same time, since the shifting hooks between adjacent sliding rakes are in different directions, the effect of shifting the material while blocking the material can be achieved, so that uniform distribution is effectively achieved. Moreover, when the sliding rake encounters piles of white tea of ​​different thicknesses during rotation driven by the motor, it will press down the receiving tray, so that when the compression spring at the bottom of the receiving tray is reset, the white tea above is driven to bounce up again, so as to achieve the effect of spreading the material again, and also achieve the effect of turning the material, and at the same time avoid the existing situation of uneven distribution when turning the material.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
