[0010] The longitudinal cylinder pushes the sliding flower basket bracket to move up to the receiving position to receive the flower basket put down by the robot;

[0011] The cylinder door opens, and the transverse cylinder drives the flower basket bracket to slide horizontally into the drying device;

[0012] The longitudinal cylinder drives the flower basket bracket to move downward, placing the flower basket on the flower basket support frame; and

[0013] When the drying device is in the discharging state, the longitudinal cylinder lifts the flower basket bracket, then the cylinder door opens, and the longitudinal cylinder drives the flower basket bracket to slide horizontally to the discharging position.

[0014] The beneficial effect of the present invention is that the double-layer drying equipment of the present invention stacks a pair of drying devices and sends the flower baskets in the corresponding drying devices in the same direction through the transfer platform provided in each drying device, so that the discharge of the two drying devices does not interfere with each other, and the upper layer can be loaded while the lower layer is discharged, or the upper layer can be discharged while the lower layer is loaded, thereby avoiding interference between the input and output of the upper and lower layers of the double-layer drying equipment and improving the utilization efficiency of the double-layer drying equipment.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] As shown in Figures 1 and 4, at least one embodiment provides a double-layer drying device, including: a pair of stacked drying devices 1; each drying device 1 is provided with a transfer platform 2; wherein each transfer platform 2 is suitable for respectively sending the flower baskets 5 in the two drying devices 1 in the same direction.

[0033] In some embodiments, a pair of drying devices 1 are stacked and arranged, and the flower baskets 5 in the corresponding drying devices 1 are sent in and out in the same direction through the transfer platform 2 set in each drying device 1, so that the discharge of the two drying devices 1 does not interfere with each other, and the upper layer can be loaded while the lower layer is discharged, or the upper layer can be discharged while the lower layer is loaded, thereby avoiding interference between the input and output of the upper and lower layers of the double-layer drying equipment and improving the utilization efficiency of the double-layer drying equipment.

[0034] As shown specifically in Figures 2 and 3, in some embodiments, the transfer platform 2 includes a flower basket bracket 24 and a flower basket support frame 23. The flower basket support frame 23 is fixedly disposed within the drying device 1 and is used to carry the flower basket 5 placed in the drying device 1. The flower basket bracket 24 is movably disposed at the bottom of the flower basket support frame 23. The flower basket bracket 24 can be removed from the drying device 1 by a corresponding drive device to receive the flower basket 5, and then moved back into the drying device 1 under the action of the corresponding drive device to place the received flower basket 5 on the flower basket support frame 23 for drying. The positioning grooves on the flower basket bracket 24 are adapted to the bottom rods of the flower basket 5, so that the flower basket 5 can be snapped into the positioning grooves on the flower basket bracket 24, allowing the flower basket 5 to move.

[0035] Specifically, the driving device includes: a transverse cylinder 21 and a longitudinal cylinder 22; the fixed end of the transverse cylinder 21 is arranged on the inner wall of the drying device 1, and the movable end is connected to the flower basket bracket 24 to push the flower basket bracket 24 to move left and right; the fixed end of the longitudinal cylinder 22 is also arranged on the inner wall of the drying device 1, and its movable end is in contact with the flower basket bracket 24 through a connecting cross bar, so that when the movable end of the longitudinal cylinder 22 is extended, the connecting cross bar is pushed to push the flower basket bracket 24 to move upward.

[0036] In some embodiments, a plurality of drying stations are equidistantly arranged in the drying device 1; a blowing device 3 is provided on the top of each drying station; and the blowing port of the blowing device 3 is arranged facing the drying station.

[0037] As shown in Figures 5 and 6, as a preferred embodiment, the number of drying stations is set to 3, and the blowing device 3 set on the top of each drying station always maintains a blowing state, so that the flower basket 5 on each drying station is dried by hot air. Specifically, the outline of the blowing chamber 30 of the blowing device 3 is approximately house-shaped, and air inlets 31 are opened on both sides of the blowing chamber 30, so that the air flow enters the blowing chamber 30, and a number of air guide plates 32 are arranged at intervals in the blowing chamber 30, and the air guide plates 32 are gradually increased from the two ends of the blowing chamber 30 to the center, so as to increase the air intake speed, and a number of air outlets are opened at the bottom of the blowing chamber 30, and the air outlets are facing the drying stations, so that the gas is blown to the flower basket 5.

[0038] As shown in Figures 7 and 8, as a preferred embodiment, a return air device 4 is further provided at the bottom of each drying station. The return air chamber 40 of the return air device 4 has a return air cavity 40 with an approximately plate-like outline, and an air guide port 42 is provided at the bottom of the return air cavity 40, and a return air port 41 is provided at the top, which is directly facing the drying station, so that the gas blown out of the blowing port enters the return air cavity 40 through the return air port 41. A conical return air plate 43 is provided in the return air cavity 40, so that the return air is faster.

[0039] As an optional embodiment, the blowing device 3 is connected to the air return device 4 through corresponding pipelines, thereby realizing the circulation of the drying air flow.

[0040] In some embodiments, cylinder doors 10 are provided on both sides of the drying device 1 located on the upper layer, so that the upper drying device 1 can be fed from one side and discharged from the other side. Cylinder doors 10 are provided on either side of the drying device 1 located on the lower layer, and the lower drying device 1 can be fed and discharged on the same side through the cylinder doors 10. In addition, a gap is provided at the bottom of each of the cylinder doors 10 for the flower basket bracket 24 to move out, so that when there is no flower basket 5 on the flower basket bracket 24 to be transported out, the cylinder door 10 does not need to be opened, and the flower basket bracket 24 can be driven out from the gap of the cylinder door 10; the drying effect can be improved and the temperature inside the drying device 1 can be ensured.

[0041] On the other hand, the present invention also provides a drying method using the above-mentioned double-layer drying equipment, including: when the drying device 1 is in the loading state, the cylinder door 10 is closed, and the flower basket bracket 24 is driven by the transverse cylinder 21 to slide horizontally out of the notch at the bottom of the cylinder door 10; the longitudinal cylinder 22 pushes the sliding flower basket bracket 24 to move up to the receiving position to receive the flower basket lowered by the robot 5; the cylinder door 10 is opened, and the transverse cylinder 21 drives the flower basket bracket 24 to slide horizontally into the drying device 1; the longitudinal cylinder 22 drives the flower basket bracket 24 to move downward and places the flower basket 5 onto the flower basket support frame 23; and when the drying device 1 is in the discharging state, the longitudinal cylinder 33 lifts the flower basket bracket 24, and then the cylinder door 10 is opened, and the longitudinal cylinder 22 drives the flower basket bracket 24 to slide horizontally to the discharging position.

[0042] As a preferred embodiment, when the drying device 1 is loading for the first time, the flower basket bracket 24 moves out of the drying device 1 to the receiving position, receives the flower basket 5 put down by the robot, and then the flower basket bracket 24 moves back into the drying device 1 to place the received flower basket 5 in the first drying position (the drying position close to the feeding position). When the drying device 1 is to load for the second time, the flower basket bracket 24 first slides out horizontally. At this time, the flower basket bracket 24 does not contact the flower basket 5 on the first drying position, so that the flower basket bracket 24 can be moved out alone, and then the flower basket bracket 24 rises to the receiving position to receive the flower basket 5. At this time, the flower basket 5 on the first drying position is also lifted up due to the rise of the flower basket bracket 24. When the flower basket bracket 24 moves back into the drying device 1 again, the flower basket bracket 24 moves the flower basket 5 received for the second time and the lifted flower basket 5 at the same time until the flower basket 5 received for the second time moves to above the first drying position. At this time, the flower basket 5 loaded for the first time has been moved to the top of the second drying position. Then, as the flower basket bracket 24 moves downward, the flower basket 5 received for the second time is placed on the first drying position, and the flower basket 5 received for the first time is transferred to the second drying position. This cycle is repeated until the flower basket 5 is discharged. Through the above-mentioned flower basket 5 loading method, the flower basket 5 is moved one station at a time, ensuring the drying effect after passing through three stations.

[0043] In some embodiments, when the drying device 1 located on the upper layer is in the loading state, the drying device 1 located on the lower layer is in the discharging state or the stopping state; and when the drying device 1 located on the lower layer is in the loading state, the drying device 1 located on the upper layer is in the discharging state or the stopping state.

[0044] As a preferred embodiment, when the upper drying device 1 is loading, the flower basket bracket 24 of the upper drying device 1 is moved out, so the flower basket bracket 24 of the lower drying device 1 is not moved out; and when the lower drying device 1 is loading, the flower basket bracket 24 of the lower drying device 1 is moved out, so the flower basket bracket 24 of the upper drying device 1 is not moved out. Even if the drying equipment always maintains the two states of upper in and lower out or lower in and upper out (interlaced), the use of this loading method can avoid the upper flower basket bracket 24 interfering with the loading and unloading of the lower flower basket bracket 24.

[0045] To sum up, the double-layer drying equipment of the present invention is arranged by stacking a pair of drying devices 1, and sending the flower baskets 5 in the corresponding drying devices 1 in the same direction through the transfer platform 2 set in each drying device 1, so that the discharge of the two drying devices 1 does not interfere with each other, and the upper layer can be loaded while the lower layer is discharged, or the upper layer can be discharged while the lower layer is loaded, thereby avoiding interference between the input and output of the upper and lower layers of the double-layer drying equipment and improving the utilization efficiency of the double-layer drying equipment.
