[0002] Existing tea drying equipment is generally drum, belt, and box-type, among which the box-type dryer is a drying equipment with a higher frequency of use. The box-type dryer uses a bracket and stacked trays to operate, spreads the tea leaves flat in the tray, and heats the inside of the box to dry the tea leaves. This drying method can handle a large amount of tea at one time, but before drying, the tea leaves need to be spread flat in the material tray, and after spreading, the tea leaves will be stacked in layers. After being placed in the drying box, since the tea leaves are in a static state, there will be a temperature difference between the outer and inner layers of the tea leaves during the drying process, so that the inner layer of the tea leaves will not be dried properly or will be over-dried, thus affecting the quality of the tea leaves.

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0027] As shown in the figure, this embodiment provides a tea processing and drying machine, including a box body 1, a material box 2, and a motor 3, wherein four support rods 11 are fixedly installed inside the box body 1, and a U-shaped groove is opened inside the support rod 11. The four support rods 11 form a "mouth"-shaped structure, such as Figure 3 As shown. A placement slot 9 is slidably installed in the four U-shaped slots. The two side surfaces of the placement slot 9 can fit with the inner side surfaces of the support rod 11. The top two sides of the placement slot 9 protrude outward, so that it can be slidably installed inside the U-shaped slot and prevent the placement slot 9 from sliding downward. The interior of the placement slot 9 is concave downward and one end is through (the through end is close to the opening of the box body 1), as shown in FIG. Figure 3 A material box 2 is slidably installed inside the placement groove 9, and the inside of the material box 2 can be used to place tea leaves that need to be dried.
[0028] The motor 3 is fixedly installed on the top of the box body 1 (the motor 3 is far away from the opening of the box body 1), and a number of active bevel gears 31 are fixedly installed on the output rod of the motor 3 (the installation of the active bevel gear 31 needs to be designed according to the actual situation). U-shaped grooves are opened at the protruding positions on both sides of the top of the placement groove 9 (the opening of the U-shaped groove is in a corresponding state), and a screw rod 33 is rotatably installed inside one of the U-shaped grooves (a circular sliding rod is fixedly installed inside the other U-shaped groove). A driven bevel gear 32 is fixedly installed at one end of the screw rod 33, and the driven bevel gear 32 meshes with the active bevel gear 31, such as Figure 4 shown.
[0029] When the output rod of the motor 3 rotates with the active bevel gear 31, it can rotate synchronously with the driven bevel gear 32, so that the driven bevel gear 32 rotates with the screw rod 33 (the motor 3 is a forward and reverse motor, and the motor 3 can rotate forward and reverse, so that the screw rod 33 can also rotate forward and reverse).
[0030] The screw rod 33 and the slide rod are in a horizontal state. A slide is rotatably installed on the circumferential surface of the screw rod 33, and a slide with the same structure is slidably installed on the circumferential surface of the slide rod. The subsequent structures are consistent, so only the structure on one side is explained.
[0031] The upper and lower end surfaces of the slide are fitted with the inner wall of the U-shaped groove. The slide will not rotate with the screw rod 33 under the restriction of the U-shaped groove. The slide can only slide horizontally along the U-shaped groove. One end of the slide extends to the outside of the U-shaped groove and is fixedly connected to a T-shaped support rod 34. Figure 6 shown.
[0032] The bottom surface of the T-shaped support rod 34 can be fitted with the inner bottom surface of the material box 2, and the roller 4 is rotatably installed on the outer side of the lower end of the T-shaped support rod 34, and the roller 4 can rotate forward and backward when the slide moves back and forth with the T-shaped support rod 34, such as Figure 6 shown.
[0033] A driving gear 41 is rotatably mounted on the inner side of the lower end of the T-shaped support rod 34. One end of the driving gear 41 is fixedly connected to the roller 4 by a connecting rod, so that the roller 4 can rotate synchronously with the driving gear 41 when rotating. Figure 6 shown.
[0034] The lower ends of the T-shaped support rod 34 are connected to mounting frames 8 of the same structure on both sides. The mounting frame 8 is a right-angled triangle structure. The interior of the mounting frame 8 is hollow and one side is through. Figure 8 The two ends of the mounting frame 8 are provided with arc grooves near each other, and the roller 4 is placed inside the arc grooves so as not to hinder the rotation of the roller 4.
[0035] Two rollers 53 are rotatably mounted on the inner side of the mounting frame 8, and a conveyor belt 7 is rotatably mounted on the circumferential surface of the rollers 53. Tooth grooves are provided at both ends of the rollers 53, and a chain 52 is mounted on the circumferential surface of the tooth grooves. A transmission gear rod 5 is rotatably mounted on the inner side of the T-shaped support rod 34, and three sprocket wheels 51 are fixedly mounted on the circumferential surface of the transmission gear rod 5, and a chain 52 is mounted on the circumferential surface of the sprocket wheel 51. Figure 7 shown.
[0036] When the driving gear 41 rotates, it can drive the transmission gear rod 5 to rotate in the opposite direction, and the transmission gear rod 5 can drive the three sprocket wheels 51 to rotate synchronously, so that the sprocket wheel 51 drives the chain 52 to rotate, so that the chain 52 can drive the roller 53 to rotate, so that the conveyor belt 7 can rotate on the circumferential surface of the roller 53, as shown in FIG. Figure 7 and Figure 5 shown.
[0037] In the first case, when the roller 4 moves outward, the roller 4 rotates clockwise, and the driving gear 41 also rotates clockwise. The driving gear 41 drives the transmission gear rod 5 to rotate counterclockwise, so that the transmission gear rod 5 can rotate synchronously with the sprocket 51.
[0038] When the sprocket 51 rotates counterclockwise, it can drive the corresponding chain 52 to rotate synchronously, so that the chain 52 can drive the roller 53 to rotate synchronously, and then the conveyor belt 7 close to the opening of the box body 1 rotates counterclockwise, and with the help of the mounting frame 8, the tea leaves in the material box 2 can be moved, so that the tea leaves experience a bottom-high-bottom operation. Baffles 81 are fixedly installed at both ends of the mounting frame 8. The baffles 81 fit the surface of the conveyor belt 7, so that when the conveyor belt 7 transports the tea leaves, the baffles 81 can prevent the tea leaves from falling into the inside of the mounting frame 8, thereby ensuring the amount of tea leaves. Figure 5 shown.
[0039] When the conveyor belt 7 approaches the box 1, the conveyor belt 7 on the other side also performs the same movement, so that the tea leaves can move back and forth.
[0040] A rotating rod 6 is fixedly installed between the two T-shaped support rods 34, and sprockets 51 are fixedly installed at both ends of the rotating rod 6. A chain 52 is installed on the circumferential surface of the sprocket 51. When the driving gear 41 rotates with the sprocket 51 on the circumferential surface, the rotating rod 6 can be made to perform a circular motion under the action of the chain 52 and the sprocket 51. Figure 7 shown.
[0041] A plurality of stirring wheels 61 are fixedly mounted on the circumferential surface of the rotating rod 6. The stirring wheels 61 are located between the two sprocket wheels 51. Figure 7 shown.
[0042] The rotating rod 6 can rotate synchronously with the stirring wheel 61. When the conveyor belt 7 moves, when the tea leaves are transported to the position of the stirring wheel 61, the tea leaves can be turned over by the stirring wheel 61. Figure 7 shown.
[0043] The working principle is as follows: the tea leaves to be dried are placed inside the material box 2 , and the material box 2 slides into the placement slot 9 , at which time the mounting frame 8 and the roller 4 are both in contact with the inner bottom surface of the material box 2 .
[0044] The output shaft of the motor 3 drives the active bevel gear 31 to rotate, and the active bevel gear 31 drives the driven bevel gear 32 to move synchronously, so that the screw rod 33 rotates.
[0045] Under the action of the screw rod 33, the slide can move with the T-shaped support rod 34, and under the action of the T-shaped support rod 34, the roller 4 can rotate. When the roller 4 rotates, it can drive the driving gear 41 to rotate synchronously. The driving gear 41 drives the transmission gear rod 5, and the transmission gear rod 5 moves with three sprockets 51. The sprocket 51 drives the chain 52 to rotate, and the chain 52 moves synchronously with the roller shaft 53 and the rotating rod 6.
[0046] Thereby, the roller 53 can rotate with the conveyor belt 7, so that the tea leaves can be moved and turned over under the action of the stirring wheel 61.
[0047] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected.
