[0020] A trough pan tea frying machine includes a trough pan 20 and a driving mechanism arranged on a frame 10. The driving mechanism drives the trough pan 20 to reciprocate in a direction perpendicular to the trough length of the trough pan 20. Above the trough pan 20, a cover 30 is arranged. The cover 30 blocks a partial area above the trough pan 20 and prevents excessive heat loss.

[0021] The covering area of the cover 30 is adjustable. Since the required covering areas for different stages or types of tea leaves during the processes of withering and shaping are different, the cover 30 arranged in this way can improve the effects of each process and avoid frequent replacement of the cover 30.

[0022] The cover plates on the cover 30 are composed of an upper cover plate 33 and a lower cover plate 32 which are arranged in an upper and lower position. The size of the overlapping area between the upper cover plate 33 and the lower cover plate 32 is adjustable. By adjusting the size of the overlapping area, the covering area of the upper cover plate 33 and the lower cover plate 32 is realized. The covering area of the upper cover plate 33 and the lower cover plate 32 = the total area of the upper cover plate 33 and the lower cover plate 32 - the area of the overlapping area.

[0023] The cover 30 and the trough pot 20 form ventilation paths 40 at both ends of the trough pot and / or above the trough pot. Regardless of the process or tea leaves, partial ventilation is necessary during the withering and sorting of the tea leaves, so the present application sets a normally open ventilation path 40.

[0024] The cover 30 is in the shape of an arc plate and the arc spans the groove width direction of the groove pot 20. The arc plate shape is more conducive to the flow blocking and containment of hot air.

[0025] The circumferential side ends of the arc-shaped cover 30 are connected to the frame 10 by brackets 90. In this way, the cover 30 is directly connected to the frame 10 and does not move with the tank, avoiding too many parts that need to be moved to increase energy consumption, and preventing parts from being damaged when the cover 30 swings.

[0026] The upper cover plate 33, the lower cover plate 32 and the middle cover plate 34 therebetween form a superimposed movable fit between the upper cover plate 33, the middle cover plate 34 and the lower cover plate 32. By adding the middle cover plate 34, a larger adjustable cover area can be achieved to meet the needs of more processes. If the adjustable cover area needs to be further increased, the number of middle cover plates 34 can be further increased.

[0027] The cover 30 comprises a frame 31, and an upper cover plate 33, a lower cover plate 32 and a middle cover plate 34 are arranged at the frame opening of the frame 31. The cover plates are installed on the same frame for easy assembly and adjustment.

[0028] The frame 31 is provided with a track 35 whose length direction is consistent with the movement direction of the upper cover plate 33, and the plate ends of the upper cover plate 33 and the middle cover plate 34 are embedded in the track 35. In this way, the horizontal movement of the cover plate can be realized.

[0029] The lower cover plate 32 is fixedly arranged with the frame 31, and a driving mechanism 50 is arranged on the upper cover plate 33. The driving mechanism 50 drives the upper cover plate 33 to adjust the size of the overlapping area of ​​each cover plate to open or close the ventilation path 40. The lower cover plate 32 is fixedly arranged to prevent the lower cover plate 32 from moving with the upper cover plate 33 due to friction when the area is adjusted.

[0030] The plate edge of the middle cover plate 34 and the plate edge of each cover plate form a cooperation to limit axial separation, so as to prevent each cover plate from separating, and at the same time, when the upper cover plate 33 moves to be separated from the middle cover plate 34, it can drive the middle cover plate 34 to move.

[0031] On both side edges of the lower cover plate 32, upward limiting flanges are provided to form a "U" - shaped cross - section. On both side edges of the upper cover plate 33, downward limiting flanges are provided to form an inverted "冖" - shaped cross - section. The limiting flanges on the lower cover plate 32 and the downward - facing limiting flanges on one side edge of the middle cover plate 34 form a limiting fit. The limiting flanges on the upper cover plate 33 and the upward - facing limiting flanges on the other side edge of the middle cover plate 34 form a limiting fit. If there is more than one middle cover plate 34, the cross - section of the middle cover plate 34 is in an "H" shape and its upward flanges form a limiting fit with each other. The limiting flanges limit each cover plate while ensuring the structural strength of each cover plate, preventing the axial separation of each cover plate from each other. During installation, they can be stacked and installed in the radial direction of each cover plate. And when the limiting flanges can contact each other, they can transmit the driving force on the upper cover plate 33 to realize the movement of the middle cover plate 34.

[0032] At least two groups of the lower cover plate 32, the upper cover plate 33, and the middle cover plate 34 are arranged. Each group of cover plates forms a unit. The upper cover plates 33 are fixedly connected by a connecting rod 331. The multi - group arranged cover plate units ensure that the ventilation path 40 above the trough pot is more evenly distributed, avoiding local tea leaves from getting damp or having a large loss of heat in local areas. The setting of the connecting rod 331 enables the synchronous movement of all the upper cover plates 33 by driving only one of the upper cover plates 33.

[0033] Above the upper cover plate 33, a nut seat 332 is provided. The nut seat 332 and the screw rod 60 form a screw - nut mechanism. The rod - length direction of the screw rod 60 is parallel to the moving direction of the upper cover plate 33. One end of the screw rod 60 forms a rotational fit with a rotating seat 321 on the lower cover plate 32. The horizontal displacement of the upper cover plate 33 is realized through the screw - nut mechanism, with a simple structure and stable operation.

[0034] On both sides in the moving direction above the upper cover plate 33, nut seats 332 are respectively provided. Driving from both sides prevents the upper cover plate 33 from running off - track and getting stuck.

[0035] Two parallel screw rods 60 corresponding to the two nut seats 332 are connected by a rotating rod 70 to achieve synchronous rotation. The rod - length direction of the rotating rod 70 is perpendicular to the rod - length direction of the screw rod 60. This ensures that the rotational speeds of the two screw rods 60 are the same.

[0036] The rotating rod 70 and the screw rod 60 are connected by two universal joints 80. This avoids the influence of dust accumulation in bevel - gear connections on the rotation effect.

[0037] The bracket 90 is a lifting mechanism that drives the cover 30 to move up and down. In this way, the change in the size of the ventilation path 40 can also be realized by the up - and - down movement of the cover 30.
