Description

Technical Field

[0001] The invention relates to the technical field of heat pump drying rooms, in particular to a seed drying room. Background Art

[0002] The working principle of the heat pump seed drying room is based on heat pump technology, which transfers heat between the evaporator and the condenser through the circulation of the refrigerant. Specifically, the refrigerant absorbs low-temperature heat energy from the environment in the evaporator, then increases its temperature and pressure through the compression of the compressor, and then releases high-temperature heat energy in the condenser, thereby achieving the purpose of converting low-temperature heat energy into high-temperature heat energy.

[0003] In the design of heat pump drying rooms, the existing air supply methods usually use horizontal air ducts or vertical air supply. In heat pump seed drying rooms, the design of hot air outlets is usually for the drying operation of the entire drying room, rather than giving priority to local treatment of the drying rack. This design can provide uniform hot air distribution when fully loaded, but when not fully loaded, the drying effect is not improved accordingly.

[0004] In actual use, the hot air from the hot air outlet is distributed as a whole, resulting in that when it is not fully loaded, the hot air first treats the entire drying room rather than individual drying racks, resulting in a more efficient energy utilization that cannot be achieved when operating under full load.

[0005] Therefore, a seed drying room is needed to solve the above problems. Summary of the invention

[0026] See also Figure 1-6 The present invention provides a technical solution: a seed drying room, comprising a heat pump 1, a drying room body 2 and an adjusting component 3, wherein a plurality of drying vehicles 4 are placed inside the drying room body 2, a hot air outlet 11 is arranged at the lower end of the heat pump 1, a hot air cavity 21 is opened at the lower end of the drying room body 2, the hot air outlet 11 is communicated with the hot air cavity 21, a support plate 211 is fixed at the upper end of the hot air cavity 21, a first through hole group 212 is opened on the support plate 211, and an adjusting component 3 is arranged at the lower end of the support plate 211.

[0027] The adjustment assembly 3 includes a support base 31, which is arranged at the lower end of the support plate 211, and a plurality of baffles 33 are arranged inside the support base 31. Support rods 32 are fixed at both ends of the baffles 33. The baffles 33 are movably installed inside the support base 31 through the support rods 32. A driving block 34 is fixed to the right side of the baffle 33 through the support rods 32. A driving chain 36 is arranged on the right side of the support base 31. A plurality of push blocks 37 are fixed to the upper end of the upper half of the driving chain 36. The position of the push blocks 37 corresponds to the driving block 34. Support gears 38 are installed on both sides of the driving chain 36. A driving motor 35 is connected to the rear side of the left support gear 38. The output end of the driving motor 35 is connected to the shaft of the supporting gear 38. When the driving motor 35 is working, it can drive the supporting gear 38 to rotate. When the supporting gear 38 rotates, the driving chain 36 can move.

[0028] Specifically, both ends of the support base 31 are fixed on the drying room body 2, and multiple groups of baffles 33 are arranged in the support base 31 at equal intervals. A driving block 34 is fixed to one side of the baffle 33 through a support rod 32. When the driving block 34 is in a horizontal state, its upper end surface does not exceed the upper end surface of the driving chain 36. The specific shape of the driving block 34 only needs to not exceed the upper end surface of the driving chain 36 when it is in a horizontal state. It is not limited here, and it is preferably Figure 5 The number of the push blocks 37 is half or less than the number of the links of the drive chain 36, and the push blocks 37 are fixedly arranged on the corresponding links of the drive chain 36, such as Figure 6 As shown, a flat plate is provided on the chain link, and the push block 37 is fixed on the flat plate of the chain link by welding or bolts. Since the baffle 33 is rotatably connected to the support base 31, when the driving block 34 and the push block 37 are not corresponding, the baffle 33 is free in a vertical state.

[0029] During use, the heat pump 1 provides a stable heat source for the drying room by absorbing external heat and converting it into hot air that can be used for heating. The hot air outlet 11 is the main channel for hot air to enter the drying room. A plurality of drying vehicles 4 are arranged inside the drying room body 2 for placing seeds to be dried. The hot air chamber 21 serves as a buffer area before the hot air enters the drying room, which helps to distribute the hot air more evenly throughout the drying room. The support plate 211 not only plays a supporting role, but also allows hot air to pass through and enter the drying room through the through hole group; the support base 31 provides a stable support structure for the adjustment component 3, and the baffle 33 can be rotated to a horizontal position to limit the outlet width of the hot air. The support rod 32 connects the baffle 33 and the support base 31 to ensure that the baffle 33 can rotate stably and flexibly. When the push block 37 on the drive chain 36 pushes the drive block 34, the baffle 33 rotates. The support gear 38 is installed on both sides of the drive chain 36 to support and guide the movement of the drive chain 36. The drive motor 35 provides power for the drive chain 36.

[0030] The support rods 32 are fixed on the upper sides of the baffle 33. When the baffle 33 is not driven, it is in a vertical state under the action of the gravity of the counterweight block 331. When subjected to a driving force, the baffle 33 will rotate around the support rods 32 to a horizontal position, thereby limiting the outlet width of the hot air. When not driven, the baffle 33 is in a vertical state, fully opening the hot air outlet, allowing the hot air to freely enter the drying room.

[0031] The upper end of the heat pump 1 is provided with a circulating air port 12, and the upper end of the drying room body 2 is provided with a circulating air cavity 22. The circulating air port 12 is communicated with the circulating air cavity 22. The lower end of the circulating air cavity 22 is provided with an upper partition 221, and the upper partition 221 is provided with a second through hole group 222. Through the circulating air port 12, the heat pump 1 can send the heated hot air into the drying room, and can also receive the circulating air returned from the drying room. This design enables the hot air to form an effective circulation between the heat pump 1 and the drying room, thereby improving the utilization efficiency of the hot air.

[0032] The driving motor 35 is fixed to the side of the drying room body 2, and the supporting gear 38 is installed between the two bearings of the bearing seat, as shown in Figure 4. The driving motor 35 is a stepping motor. By controlling the stepping angle and rotation speed of the stepping motor, the baffle 33 can be accurately controlled, so that the width of the hot air outlet can be flexibly adjusted according to the drying requirements, thereby improving the drying efficiency and energy utilization efficiency.

[0033] A door 23 is installed on the rear side of the drying room body 2, a sealing gasket 231 is fixed on the inner side of the door 23, and a handle 232 is installed on the outer side of the door 23. By opening the door 23, the drying cart 4 filled with seeds to be dried can be pushed into the drying room, and the drying cart 4 can be pushed out after the drying is completed; the sealing effect of the sealing gasket 231 can effectively prevent the hot air inside the drying room from leaking out, and at the same time, it can also prevent the outside cold air and moisture from entering the drying room. The handle 232 improves the convenience of operation.

[0034] The drying cart 4 includes a drying frame 41, and a pulley 42 is installed at the corner of the lower end of the drying frame 41. The pulley 42 rolls on the upper end of the support plate 211. Through the rolling friction between the pulley 42 and the support plate 211, the drying cart 4 can be easily pushed to move in the drying room, so that the seeds can be conveniently sent to the drying position or taken out from the drying position.

[0035] As an embodiment of the present invention: when the heat pump seed drying room is adjusted in a non-full load state, the drive motor 35 is first started. After the drive motor 35 works, it will drive the support gear 38 on the left to rotate. The support gear 38 drives the drive chain 36 to start moving through the gear transmission method. The push block 37 on the upper half of the drive chain 36 passes through the position of each drive block 34 one by one as the chain moves. When the push block 37 contacts the drive block 34, a thrust is applied to make the drive block 34 drive the support rod 32 and the baffle 33 to start rotating. Since the support rod 32 is fixed on both sides of the baffle 33, when the driving force is applied, the baffle 33 will rotate around the support rod 32 to a horizontal position. As the drive chain 36 continues to move, more push blocks 37 will push the corresponding drive blocks 34 in turn, so that more baffles 33 rotate to a horizontal position, and the width of the hot air outlet 11 will gradually decrease, limiting the outlet width of the hot air, so that the distribution of the hot air is adjusted according to the drying requirements; thereby completing the adjustment of the heat pump seed drying room.
