[0052] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0053] like Figure 1 and Figure 4 As shown, at least one embodiment provides a double-layer drying equipment, including: a pair of stacked drying devices 1; each of the drying devices 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.

[0054] 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 arranged 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 upper and lower layers of the double-layer drying equipment in feeding and discharging, and improving the utilization efficiency of the double-layer drying equipment.

[0055] Specific as Figure 2 and Figure 3As shown, 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 arranged in 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 arranged at the bottom of the flower basket support frame 23. The flower basket bracket 24 can be moved out of the drying device 1 to receive the flower basket 5 through a corresponding driving device, and moved back into the drying device 1 under the action of the corresponding driving device to place the received flower basket 5 on the flower basket support frame 23 for drying. The positioning groove provided on the flower basket bracket 24 is adapted to the end plate of the flower basket 5, so that the flower basket 5 can be inserted into the positioning groove provided on the flower basket bracket 24, so that the flower basket bracket 24 drives the flower basket 5 to move.

[0056] 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.

[0057] In some embodiments, a plurality of drying stations are equidistantly arranged in the drying device 1; a blowing device 3 is arranged on the top of each drying station; and the blowing port of the blowing device 3 is arranged directly facing the drying station.

[0058] like Figure 5 and Figure 6 As shown, as a preferred embodiment, the number of drying stations is set to 3, and the blowing device 3 arranged 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 plurality 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 plurality of blowing ports are opened at the bottom of the blowing chamber 30, and the blowing ports are directly opposite to the drying stations, so that the gas is blown to the flower basket 5.

[0059] like Figure 7 and Figure 8As shown, as a preferred embodiment, a return air device 4 is further provided at the bottom of each drying station, and the top of the return air device 4 is arranged in a slope, that is, the contour of the return air chamber 40 is approximately plate-shaped, and an air guide port 42 is provided at the bottom of the return air chamber 40, and a return air port 41 is provided at the top, and it is directly opposite to the drying station, so that the gas blown out of the blowing port enters the return air chamber 40 through the return air port 41, and a conical return air plate 43 is provided in the return air chamber 40, so that the return air is faster.

[0060] As an optional embodiment, the blowing device 3 is connected to the air return device 4 through corresponding pipelines, so as to realize the circulation of drying airflow.

[0061] 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 for the flower basket bracket 24 to move out is opened at the bottom of each of the cylinder doors 10, 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 in the drying device 1 can be ensured.

[0062] As an optional embodiment, when the drying device 1 is in a loading state, the flower basket bracket 24 is driven by the transverse cylinder 21 to slide out horizontally; the longitudinal cylinder 22 pushes the sliding flower basket bracket 24 to move up to the receiving position to receive the flower basket 5 put down by the robot; 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 a discharging state, the longitudinal cylinder 22 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 out horizontally to the discharging position.

[0063] 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 to receive 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 material is discharged. Through the above-mentioned flower basket 5 loading method, the flower basket 5 is moved one station at a time, thereby ensuring the drying effect after passing through three stations.

[0064] 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.

[0065] 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 from interfering with the loading and unloading of the bottom layer.

[0066] To sum up, the double-layer drying equipment of the utility model 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 arranged 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 upper and lower layers of the double-layer drying equipment in feeding and discharging, and improving the use efficiency of the double-layer drying equipment.
