Description

Technical Field

[0001] This utility model relates to the field of heat pump drying room technology, specifically a seed drying room. Background Technology

[0002] The working principle of a heat pump seed drying room is based on heat pump technology, which transfers heat between the evaporator and condenser through the circulation of refrigerant. Specifically, the refrigerant absorbs low-temperature heat energy from the environment in the evaporator, then its temperature and pressure are increased by the compressor, and finally high-temperature heat energy is released 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, existing air supply methods typically employ horizontal or vertical airflow. In heat pump seed drying rooms, the design of the hot air outlets usually targets the entire drying chamber for drying operations, rather than prioritizing localized treatment of the drying racks. This design can provide uniform hot air distribution when fully loaded, but the drying effect is not correspondingly improved when not fully loaded.

[0004] In actual use, the hot air from the hot air outlet is distributed as a whole. This means that when the machine is not fully loaded, the hot air will first affect the entire drying chamber, rather than individual drying racks. As a result, more efficient energy utilization cannot be achieved when the machine is not fully loaded.

[0005] Therefore, a seed drying room is needed to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a seed drying room that solves the problem mentioned in the background technology that the hot air from the hot air outlet is distributed as a whole, which causes the hot air to treat the entire drying room first, rather than individual drying racks, when not fully loaded, resulting in the inability to achieve more efficient energy utilization when operating at full capacity.

An adjustment component is provided at the lower end of the support plate.

[0009] Preferably, the adjustment component includes a support base, which is disposed at the lower end of the support plate. The support base has multiple sets of baffles inside, and support rods are fixed at both ends of the baffles. The baffles are movably installed inside the support base via two support rods, and a drive block is fixed at one end of the baffle via a support rod.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a seed drying room, including a heat pump 1, a drying room body 2, and an adjustment component 3. Multiple drying carts 4 are placed inside the drying room body 2. A hot air outlet 11 is provided 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 communicates 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. An adjustment component 3 is provided at the lower end of the support plate 211.

[0027] The adjustment assembly 3 includes a support base 31, which is located at the lower end of the support plate 211. Multiple sets of baffles 33 are installed inside the support base 31, with support rods 32 fixed to both ends of each baffle 33. The baffles 33 are movably mounted inside the support base 31 via the support rods 32. A drive block 34 is fixed to the right side of the baffle 33 via the support rods 32. A drive chain 36 is located on the right side of the support base 31. Multiple sets of push blocks 37 are fixed to the upper half of the drive chain 36, with the positions of the push blocks 37 corresponding to the drive blocks 34. Support gears 38 are installed on both sides of the drive chain 36, and a drive motor 35 is connected to the rear side of the left support gear 38. The output end of the drive motor 35 is connected to the shaft of the support gear 38. When the drive motor 35 operates, it drives the support gear 38 to rotate, which in turn moves the drive chain 36.

[0028] Specifically, the two ends of the support base 31 are fixed to the drying chamber body 2. Multiple sets of baffles 33 are equally spaced inside the support base 31. A drive block 34 is fixed to one side of the baffle 33 by a support rod 32. When the drive block 34 is in a horizontal state, its upper end face does not exceed the upper end face of the drive chain 36. The specific shape of the drive block 34 is only required to ensure that its upper end face does not exceed the upper end face of the drive chain 36 when it is in a horizontal state. It is not limited here, but preferably it is... Figure 5 The specific shape within. The number of push blocks 37 is half or less of the number of links in the drive chain 36. The push blocks 37 are fixedly mounted 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 to 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 drive block 34 and the push block 37 are not aligned, the baffle 33 is freely in a vertical state.

[0029] During operation, the heat pump 1 absorbs external heat and converts it into hot air that can be used for heating, providing a stable heat source for the drying room. The hot air inlet 11 is the main channel for hot air to enter the drying room. Multiple drying carts 4 are set inside the drying room body 2 to place the seeds to be dried. The hot air chamber 21 serves as a buffer area before the hot air enters the drying room, helping the hot air to be distributed more evenly throughout the drying room. The support plate 211 not only provides support 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. The baffle 33 can be rotated to a horizontal position to limit the width of the hot air outlet. The support rod 32 connects the baffle 33 and the support base 31, ensuring 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 will rotate. 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 to the drive chain 36.

[0030] The support rod 32 is fixed on both sides of the baffle 33 slightly above. When the baffle 33 is not driven, it is in a vertical state under the gravity of the counterweight 331. When it is driven, the baffle 33 will rotate around the support rod 32 to a horizontal position, thereby limiting the width of the hot air outlet. When the baffle 33 is in a vertical state, the hot air outlet is fully opened, allowing the hot air to enter the drying room freely.

[0031] A circulating air vent 12 is provided at the upper end of the heat pump unit 1, and a circulating air cavity 22 is provided at the upper end of the drying chamber body 2. The circulating air vent 12 communicates with the circulating air cavity 22. An upper partition 221 is provided at the lower end of the circulating air cavity 22, and a second through hole group 222 is provided on the upper partition 221. Through the circulating air vent 12, the heat pump unit 1 can send heated hot air into the drying chamber, and at the same time, it can also receive the circulating air returning from the drying chamber. This design enables the hot air to form an effective circulation between the heat pump unit 1 and the drying chamber, improving the utilization efficiency of the hot air.

[0032] The drive motor 35 is fixed to the side of the drying chamber body 2, and the support gear 38 is installed between the two bearings of the bearing seat, as shown in Figure 4. The drive motor 35 is a stepper motor. By controlling the step angle and rotation speed of the stepper motor, the baffle 33 can be precisely 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 chamber 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 chamber, and the drying cart 4 can be pushed out after drying is completed. The sealing gasket 231 can effectively prevent the hot air inside the drying chamber from leaking out, and can also prevent cold air and moisture from entering the drying chamber. The handle 232 improves the convenience of operation.

[0034] The drying cart 4 includes a drying rack 41, and a pulley 42 is installed at the lower corner of the drying rack 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 moved in the drying room, so as to conveniently send the seeds into the drying position or take them out from the drying position.

[0035] As an embodiment of this utility model: When adjusting the heat pump seed drying chamber under non-load conditions, the drive motor 35 is started first. After the drive motor 35 starts working, 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 gear transmission. 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, it will apply a thrust, causing the drive block 34 to 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 slightly above, when it is driven, 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 sequence, causing more baffles 33 to rotate to a horizontal position. The width of the hot air outlet 11 will gradually decrease, limiting the outlet width of the hot air, so that the distribution of hot air can be adjusted according to the drying requirements; thus completing the adjustment of the heat pump seed drying chamber.
