[0032] like Figures 1 to 8As shown, a tea product raw material drying device provided by an embodiment of the present invention includes a drying cylinder 110, and a base 111 placed on the ground is provided at the bottom of the drying cylinder 110; a rotating frame 130 is provided for rotation inside the drying cylinder 110, and a plurality of supporting plates 140 distributed in the up-and-down directions are fixedly provided on the rotating frame 130, the supporting plate 140 is a spiral spring bar and has a circular ring in the center, and a slider 144 is provided on the inner circumference of the circular ring, and the outer ring of the supporting plate 140 is fixedly connected to the rotating frame 130, and a guide rod 150 is fixedly provided at the center of the drying cylinder 110, and the guide rod 150 extends in the up-and-down direction, and a plurality of driving grooves are provided on the outer circumference of the guide rod 150, and the driving grooves correspond to the slider 144 one by one; when the rotating frame 130 reciprocates inside the drying cylinder 110, the supporting plate 140 is driven to rotate synchronously around the guide rod 150, and the slider 144 slides along the driving groove, so that the supporting plate 140 switches back and forth between a cone and an inverted cone. The spiral spring bar is a metal spring bar, so that the carrier plate 140 can be stretched and deformed in the up and down directions, and can be in a cone or inverted cone shape, and the spiral spring bar is evenly distributed with air holes. The carrier plate 140 switches back and forth between the cone and the inverted cone, so that the spiral spring bar can form a spiral conveying auger, and the spiral conveying auger continuously conveys the tea product raw materials accumulated thereon along the rotation direction of the spiral spring bar, so that the tea product raw materials can be evenly distributed on the carrier plate 140, thereby improving the drying effect of the tea product raw materials.

[0033] In one embodiment, the driving groove includes a first spiral groove 152 and a second spiral groove 154 distributed vertically, and the first spiral groove 152 and the second spiral groove 154 have the same spiral direction and both surround the guide rod 150. The first spiral groove 152 is used to guide the slider 144 to move upward, so that the center of the carrier plate 140 is stretched upward to form an inverted cone; the second spiral groove 154 is used to guide the slider 144 to move downward, so that the center of the carrier plate 140 is stretched downward to form a cone. The dimensions of the first spiral groove 152 and the second spiral groove 154 in the vertical direction make the gap between the spiral spring bars of the carrier plate 140 smaller after stretching, and the gap cannot pass the tea product raw materials, thereby preventing the tea product raw materials from falling.

[0034] In one embodiment, an arc-shaped slide groove 151 is connected between the first spiral groove 152 and the second spiral groove 154, and the plane where the arc-shaped slide groove 151 is located is parallel to the horizontal plane. In the initial state, the slider 144 is located in the middle of the arc-shaped slide groove 151. This facilitates the slider 144 to slide along the first spiral groove 152 or the second spiral groove 154.

[0035] In one embodiment, both ends of the first spiral groove 152 are connected to first vertical grooves 153, and both ends of the second spiral groove 154 are connected to second vertical grooves 155. The first vertical groove 153 and the second vertical groove 155 both extend in the up-down direction, and the first vertical groove 153 and the second vertical groove 155 are used to reset the slider 144.

[0036] In one embodiment, an annular baffle 142 is provided on the carrier plate 140, and the annular baffle 142 is fixedly connected to the outer ring of the spiral spring bar. The annular baffle 142 is located on the upper side of the carrier plate 140 and extends along the axial direction of the carrier plate 140. The annular baffle 142 can stop the tea product raw materials sliding radially along the carrier plate 140 to prevent the tea product raw materials from falling to the bottom of the drying cylinder 110.

[0037] In one embodiment, the rotating frame 130 includes a plurality of support rods 132 extending in the up-down direction, the support rods 132 are evenly distributed around the circumference of the drying drum 110, and a plurality of support platforms 133 distributed up-down are provided on each of the support rods 132, and the annular baffle 142 is fixedly disposed on the support platforms 133. Since the outer ring of the spiral spring bar is fixed, the circular ring at the center of the spiral spring bar can stretch the spiral spring bar in the up-down direction when it moves up-down.

[0038] Specifically, a plurality of fixing ears are provided on the outer periphery of the annular baffle 142 , and the fixing ears are fixedly connected to the support platform 133 by bolts 143 .

[0039] In one embodiment, a fixing plate 156 is provided at the bottom of the guide rod 150 , and the guide rod 150 is fixed to the bottom of the drying drum 110 through the fixing plate 156 .

[0040] In one embodiment, a rotating shaft 131 is provided at the top of the rotating frame 130, and a driving motor 121 is provided at the top of the drying drum 110, and the driving motor 121 is used to drive the rotating shaft 131 to rotate. An upper cover 120 is provided at the top of the drying drum 110, and the rotating shaft 131 passes through the upper cover 120 and is transmission-connected to the output end of the driving motor 121.

[0041] In one embodiment, a tea-leaf access door 112 is hingedly connected to the side wall of the drying cylinder 110, and the tea-leaf access door 112 is used for personnel to place tea product raw materials on the carrying plate 140. The tea-leaf access door 112 is hingedly connected to the drying cylinder 110 through a hinge 116, and a handle 113 is provided on the tea-leaf access door 112, which is convenient for personnel to open the tea-leaf access door 112, and an observation window 114 is provided on the tea-leaf access door 112, which is convenient for personnel to observe the drying status of the tea product raw materials in real time.

[0042] In one embodiment, the bottom of the drying drum 110 is provided with an air inlet 115, and the top of the drying drum 110 is provided with an air outlet 122, and hot air enters through the air inlet 115 and flows out from the air outlet 122. The air outlet 122 and the driving motor 121 are both arranged on the upper cover 120.

[0043] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0044] In this embodiment, viewed from top to bottom, the rotation direction of the spiral spring bar from inside to outside is clockwise, and the rotation directions of the first spiral groove 152 and the second spiral groove 154 are both counterclockwise.

[0045] In the initial state, the carrier plate 140 is a horizontal plate, and the slider 144 is located in the arc-shaped slide groove 151. The tea taking and placing door 112 is opened, and the tea product raw materials are placed on each layer of the carrier plate 140, and hot air is introduced into the air inlet 115. The hot air passes through the air holes of the spiral spring bars on each carrier plate 140 to dry the tea product raw materials, and finally flows out from the air outlet 122.

[0046] Then the driving motor 121 is started, and the driving motor 121 first drives the rotating frame 130 to rotate clockwise, and the rotating frame 130 drives the carrying plate 140 to rotate clockwise around the guide rod 150, and the slider 144 on the central ring of the carrying plate 140 will enter the first spiral groove 152 upward. Under the guidance of the first spiral groove 152, the ring at the center of the carrying plate 140 will move upward, and then the carrying plate 140 will be in an inverted cone shape, and the opening of the inverted cone will face downward. Under the action of gravity, the tea product raw materials at the center of the carrying plate 140 will slide to the surrounding areas of the carrying plate 140, realizing automatic stirring of the tea product raw materials. At the same time, the clockwise rotation of the carrying plate 140 forms a spiral conveying auger to continuously convey the tea product raw materials from the surrounding areas of the carrying plate 140 to the center of the carrying plate 140 upward, so that the tea product raw materials can be evenly and continuously distributed on the spiral spring bars of the carrying plate 140, avoiding the accumulation of tea product raw materials around the carrying plate 140, which is conducive to improving the uniformity of drying.

[0047] When the slider 144 enters the first vertical groove 153 , under the elastic force of the carrier plate 140 itself, the slider 144 slides along the first vertical groove 153 and enters the arc-shaped slide groove 151 , thereby resetting the slider 144 and restoring the carrier plate 140 to a horizontal plate.

[0048] Then the driving motor 121 is controlled to drive the rotating frame 130 to rotate counterclockwise, and the rotating frame 130 drives the carrying plate 140 to rotate counterclockwise around the guide rod 150. At the same time, the slider 144 on the central ring of the carrying plate 140 will enter the second spiral groove 154 downward. Under the guidance of the second spiral groove 154, the ring at the center of the carrying plate 140 will move downward, and then the carrying plate 140 is conical, and the opening of the cone faces upward. Under the action of gravity, the tea product raw materials at the center of the carrying plate 140 will slide toward the center of the carrying plate 140, realizing automatic stirring of the tea product raw materials. At the same time, the counterclockwise rotation of the carrying plate 140 forms a spiral conveying auger to continuously convey the tea product raw materials from the center of the carrying plate 140 to the surroundings of the carrying plate 140 upward, so that the tea product raw materials can be evenly and continuously distributed on the spiral spring strips of the carrying plate 140, avoiding the accumulation of the tea product raw materials at the center of the carrying plate 140, which helps to improve the drying uniformity. In this way, the tea product raw materials can be dried and the drying effect of the tea product raw materials can be guaranteed.

[0049] When the slider 144 enters the second vertical groove 155, under the elastic force of the carrier plate 140 itself, the slider 144 slides along the second vertical groove 155 to enter the arc-shaped slide groove 151, so that the slider 144 is reset and the carrier plate 140 is restored to a horizontal plate. In the process of the carrier plate 140 restoring from an inverted cone or cone shape to a horizontal plate, the tea product raw materials on the carrier plate 140 are thrown upward, promoting the contact between the tea product raw materials and the hot air, thereby improving the drying effect.

[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
