[0030] When in use, the staff puts the whole dried pickled mustard greens on the belt 11 between the two baffles 10. After placing one piece of dried pickled mustard greens, the staff turns the first handle 23, the first handle 23 drives the first pulley 22 to rotate, the first pulley 22 drives the belt 11 to rotate, and the belt 11 drives the baffle 10 to move, thereby moving the placed dried pickled mustard greens outward and creating an empty space.

The lower end of the fixed frame 12 is provided with an adjusting component for moving the fixed frame 12 to change the inclination angle of the perforated conveyor belt 15.

[0033] When in use, the staff rotates the second handle 26, the second handle 26 drives the connecting rod 27 to rotate, the connecting rod 27 drives the second pulley 25 to rotate, and the second pulley 25 drives the leaky conveyor belt 15 to rotate. While the leaky conveyor belt 15 moves, the staff spreads the dried preserved vegetables on the leaky conveyor belt 15.

[0034] When it is folded up, a collecting bag is opened at one end of the leaky conveyor belt 15, and then the staff rotates the second handle 26 to allow the dried preserved vegetables on the leaky conveyor belt 15 to enter the collecting bag.

[0035] The adjustment assembly includes a mounting plate 18, which is horizontally arranged below the fixed frame 12, and both ends of the mounting plate 18 are mounted on the side walls of the two vertical plates 3. An electric telescopic rod 16 for moving the fixed frame 12 is mounted on the upper end of the mounting plate 18, and the output end of the electric telescopic rod 16 is mounted on the lower end of the fixed frame 12.

[0036] The heat collecting and drying mechanism includes a heat collecting tube 9, an S-shaped heat dissipation coil 24 for heating and drying the dried plums on the leaking hole conveyor belt 15 is installed between the fixed plate 19 and the connecting rod 27, the heat collecting tube 9 is horizontally installed on the upper ends of the two vertical plates 3, and a water pump 6 is installed on the side wall of the vertical plate 3 near the output end of the heat collecting tube 9, an output pipe 7 is installed at the output end of the heat collecting tube 9, and the end of the output pipe 7 away from the heat collecting tube 9 is installed at the input end of the water pump 6, and the output end of the water pump 6 is installed with a first connecting pipe 5, and the end of the first connecting pipe 5 away from the water pump 6 is installed at the input end of the S-shaped heat dissipation coil 24, the input end of the heat collecting tube 9 is installed with an input pipe 14, and the end of the input pipe 14 away from the heat collecting tube 9 is installed at the output end of the S-shaped heat dissipation coil 24, the input pipe 14 and the first connecting pipe 5 are both provided with redundant lengths to facilitate the rotation adjustment of the fixed frame 12 and the fixed plate 19, and the heat collecting tube 9 and the S-shaped heat dissipation coil 24 are both filled with water.

[0037] Under the action of the sun, the heat collecting tube 9 uses solar energy to heat the water inside, and then starts the water pump 6. The water pump 6 draws hot water inside the heat collecting tube 9 through the output pipe 7, and then transports the hot water to the inside of the S-shaped heat dissipation coil 24 through the first connecting pipe 5. The S-shaped heat dissipation coil 24 dissipates heat to dry the dried preserved vegetables on the leaking hole conveyor belt 15, and then the S-shaped heat dissipation coil 24 transports water to the inside of the heat collecting tube 9 through the input pipe 14.

[0038] The light chasing mechanism includes a light chaser 8, which is installed on the upper end of one of the vertical plates 3. A controller 20 is installed on the upper end of the support plate 17, and a driving wheel 2 for moving the base 1 is installed on the lower end of the base 1.

[0039] When in use, the light chaser 8 measures the direction of sunlight in real time and sends the information to the controller 20. The controller 20 controls the driving wheel 2, which drives the base 1 to move, and the base 1 drives the driving wheel 2 and the support plate 17 to move, thereby adjusting the angle of the leaky conveyor belt 15 and the dried plums on the fixed frame 12 so that the sunlight is directly facing the dried plums.

[0040] The working principle of the easy-to-retract dried plum drying equipment:

[0041] When drying a whole root of dried plum, the electric telescopic rod 16 is started to extend, and the output end of the electric telescopic rod 16 pushes the fixed frame 12 to move upward. Under the action of the hinge, the fixed frame 12 drives the fixed plate 19 to move, and the fixed plate 19 drives the leaky conveyor belt 15 to move, thereby tilting the leaky conveyor belt 15, and the fixed plate 19 away from the side of the fixed frame 12 pushes the telescopic rod 4 to retract.

[0042] Then the staff puts the whole dried plums on the belt 11 between the two baffles 10, and makes the dried plums fork and hang down on the perforated conveyor belt 15. After one dried plum is placed, the staff turns the first handle 23, the first handle 23 drives the first pulley 22 to rotate, the first pulley 22 drives the belt 11 to rotate, and the belt 11 drives the baffle 10 to move, thereby moving the placed dried plums to the outside and rotating out an empty space. Then the staff puts a new whole dried plum on the empty space. In this way, the fixed frame 12 is filled with dried plums.

[0043] When putting away, the staff turns the first handle 23 to move the dried plums on the belt 11 toward itself, thereby putting away the dried plums.

[0044] When the cut preserved vegetables are dried after drying, the electric telescopic rod 16 is started to retract, and the output end of the electric telescopic rod 16 drives the fixed frame 12 to move downward. Under the action of the hinge, the fixed frame 12 drives the fixed plate 19 to move, and the fixed plate 19 drives the leaky hole conveyor belt 15 to move, so that the leaky hole conveyor belt 15 swings to a horizontal state, and the fixed plate 19 away from the side of the fixed frame 12 pulls the telescopic rod 4 to extend.

[0045] Then the staff member rotates the second handle 26, the second handle 26 drives the connecting rod 27 to rotate, the connecting rod 27 drives the second pulley 25 to rotate, the second pulley 25 drives the leaky conveyor belt 15 to rotate, and while the leaky conveyor belt 15 moves, the staff member spreads the dried preserved vegetables on the leaky conveyor belt 15.

[0046] When it is folded up, a collecting bag is opened at one end of the leaky conveyor belt 15, and then the staff rotates the second handle 26 to allow the dried preserved vegetables on the leaky conveyor belt 15 to enter the collecting bag.

[0047] While drying, under the action of the sun, the heat collecting tube 9 uses solar energy to heat the water inside, and then starts the water pump 6. The water pump 6 draws hot water inside the heat collecting tube 9 through the output pipe 7, and then transports the hot water to the inside of the S-shaped heat dissipation coil 24 through the first connecting pipe 5. The S-shaped heat dissipation coil 24 dissipates heat to dry the dried preserved vegetables on the leaking hole conveyor belt 15, and then the S-shaped heat dissipation coil 24 transports water to the inside of the heat collecting tube 9 through the input pipe 14.

[0048] While drying, the light chaser 8 measures the direction of sunlight in real time and sends the information to the controller 20. The controller 20 controls the driving wheel 2, which drives the base 1 to move, and the base 1 drives the driving wheel 2 and the support plate 17 to move, thereby adjusting the angle of the dried plums on the leaky conveyor belt 15 and the fixed frame 12 so that the sunlight is directly facing the dried plums.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
