Description

Technical Field

[0001] This invention belongs to the field of grain air conditioning, specifically a multi-functional grain-specific air conditioning cooling unit. Background Technology

[0002] A grain-specific air conditioning cooling unit is a device specifically designed for cooling grain during storage. It transfers cold energy to the grain pile through a refrigeration system, lowering the grain temperature and thus inhibiting grain respiration, microbial growth and reproduction, and pest activity. This effectively extends the storage period of the grain, ensuring its quality and safety, and greatly improves the efficiency and management level of grain storage. It is an indispensable piece of equipment in modern grain storage.

[0003] Existing grain depot air conditioning systems mostly use fixed ducts or manual airflow switching for air delivery. In actual operation, when priority is needed to cool the grain surface to prevent surface mold, the ventilation needs of the grain core area are often not effectively met. Conversely, when the focus is on cooling the grain core to eliminate the heat core phenomenon, it is easy to cause excessive drying of the grain surface or the risk of condensation. More seriously, traditional duct switching mechanisms mostly rely on mechanical baffles for step-by-step operation, which has problems such as slow switching action and asynchronous opening and closing of ducts. For example, when closing the duct leading to the grain surface, the duct leading to the grain core may not open in time, resulting in a vacuum period of no duct conduction in the system for a short time. This causes wind pressure accumulation and airflow turbulence, which not only causes sudden changes in fan load and increases energy consumption, but may also damage the duct structure due to instantaneous airflow impact, affecting the equipment life.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a multi-functional grain-specific air conditioning cooling unit. Summary of the Invention

This solves the problems of existing grain depot air conditioners, which mostly use fixed or manual air duct switching, making it difficult to simultaneously cool different areas. The air duct switching relies on mechanical baffles, resulting in asynchronous actions and a vacuum period where one air duct is closed while another is not open. This leads to air pressure buildup, airflow turbulence, sudden changes in fan load, increased energy consumption, and even damage to the air duct structure.

[0016] Preferably, a sliding groove is provided on one side of the inner wall of the structural box, and a slider is fixedly connected to the other side of the screw sleeve, with one end of the slider slidably connected to the inner cavity of the sliding groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention effectively solves the problems of inconsistent cooling zones, vacuum periods during switching, airflow turbulence, and equipment damage caused by asynchronous switching of air conditioning ducts in existing grain depots. The invention utilizes a force-bearing rod in the duct switching mechanism to rotate hollow and solid plates, achieving duct on / off control. The structure is simple and reliably sealed. The drive mechanism uses gear one and gear two meshing, along with a small pulley, transmission belt, and large pulley, to synchronously switch the two ducts in opposite directions. This avoids pressure buildup and airflow impact caused by simultaneous duct closure, protecting the dual condenser fans and duct structure, and extending equipment lifespan. The gear meshing state is adjusted via the handle, lead screw, threaded sleeve, vertical rod, and outer frame of the docking mechanism, enabling switching between synchronous and independent control modes to adapt to different operating conditions. The protective shell effectively protects the transmission components, improving operational stability. The overall structure operates smoothly and switches seamlessly, reducing manual intervention, improving temperature control accuracy, ensuring uniform cooling of the surface and deeper layers of the grain pile, and enhancing grain storage safety and energy efficiency.

[0019] This invention utilizes a combination of large and small pulleys to achieve smooth long-distance power transmission via belt drive. When the drive motor rotates the small pulley, the power is efficiently transmitted to the large pulley via the transmission belt, which in turn drives the force rod to rotate, completing the duct switching action. This structure avoids the spatial layout limitations and insufficient torque problems that may result from direct drive. Furthermore, the ratio design of the large and small pulleys achieves a certain speed reduction and torque increase effect, making the duct switching process smoother and more powerful, reducing start-stop impact, and improving control precision. In addition, belt drive has the advantages of buffering and vibration absorption, and low operating noise, effectively reducing vibration and noise during equipment operation and extending the service life of transmission components. The large pulley is located outside the air conditioning cooling unit casing and is directly connected to the force rod, facilitating installation, commissioning, and subsequent maintenance. The overall structure is simple and reliable, improving the response performance and operational stability of the duct switching mechanism.

[0020] This invention achieves power linkage and synchronous control between the two drive rods through the meshing of gear one and gear two. When drive rod one is driven to rotate by the drive motor, its outer ring gear one can directly mesh and transmit power to gear two, thereby driving drive rod two to rotate synchronously in the opposite direction. This ensures that the switching mechanisms of the two air ducts are coordinated and synchronized, effectively avoiding the problem of simultaneous closure of air ducts due to timing differences in traditional step-by-step control. This gear transmission structure has a rapid response and high transmission accuracy, ensuring that the hollow plate and the solid plate achieve synchronous opening and closing during the switching process. It eliminates the risk of wind pressure accumulation and airflow turbulence, and improves the stability and safety of system operation. At the same time, the gear meshing state can be disengaged or engaged by the outer frame driving gear two to move laterally, which facilitates switching between synchronous mode and independent control mode, enhances the equipment's adaptability to operating conditions, and has a compact structure and high reliability.

[0029] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] As attached Figure 1 To be continued Figure 7 As shown:

[0031] Example 1: This invention provides a multifunctional grain-specific air conditioning cooling unit, including an air conditioning cooling unit shell 1. The inner cavity of the air conditioning cooling unit shell 1 is provided with a dual condenser fan 3. Both sides of the inner wall of one side of the air conditioning cooling unit shell 1 are provided with through holes 8. One side of the through hole 8 is provided with an air duct switching mechanism 7. The air duct switching mechanism 7 includes a force-bearing rod 701. Two short blocks 704 are fixedly connected to the outer ring of the force-bearing rod 701 and along the circumferential direction of the force-bearing rod 701. One end of one short block 704 is fixedly connected to a hollow plate 702, and one end of the other short block 704 is fixedly connected to a solid plate 703. The inner cavity of the hollow plate 702 is connected to the inner cavity of the adjacent through hole 8.

[0032] A drive mechanism 2 is provided on one side of the air conditioning cooling unit housing 1. The drive mechanism 2 includes a mounting box 201. Drive rod 1 203 and drive rod 209 are respectively provided on both sides of the inner cavity of the mounting box 201. One end of the force rod 701 passes through the side wall of the adjacent air conditioning cooling unit housing 1 and is fixedly connected to a large pulley 212. Small pulleys 206 are respectively sleeved on the outer rings of drive rod 1 203 and drive rod 209. Adaptive through grooves 208 are provided on both sides of the outer wall of one side of the air conditioning cooling unit housing 1. The outer rings of the small pulleys 206 and the corresponding outer rings of the large pulleys 212 are connected by a transmission belt 207 passing through the adjacent adaptive through grooves 208. Protective shells 5 are provided on both sides of the outer wall of one side of the air conditioning cooling unit housing 1.

[0033] One end of the force-bearing rod 701 passes through the side wall of the air conditioning cooling unit housing 1 via a bushing and is fixedly connected to one end of the corresponding large pulley 212. One end of the solid plate 703 and one end of the hollow plate 702 are respectively attached to the side wall of the adjacent air conditioning cooling unit housing 1.

[0034] As can be seen from the above, when the equipment is put into operation, the operator first connects the two air outlet pipes 6 to the air supply pipes leading to the grain core area and the grain surface area in the grain warehouse, respectively, and connects the temperature sensor signals of the grain core area and the grain surface area to the control system of the air conditioning cooling unit to achieve real-time monitoring of the ambient temperature. In the operating mode that requires synchronous switching of the two air ducts, that is, when one air duct is closed while the other air duct is opened, the operator manually rotates the handle 402 to drive the screw fixedly connected to it to rotate inside the structural box 401. Since the slider on the outside of the screw sleeve 403 forms a sliding limit engagement with the sliding groove on the inner wall of the structural box 401, Therefore, the rotational motion of the lead screw is converted into the linear displacement of the screw sleeve 403 in the horizontal direction. The screw sleeve 403 drives the vertical rod 404, which is fixedly connected to it, to move, thereby pushing the outer frame 210 to move laterally as a whole. A bearing sleeve is fixed inside the outer frame 210, and the gear 211 is fixedly connected to the outer ring of the bearing sleeve. Therefore, the movement of the outer frame 210 causes the gear 211 to move laterally until it meshes with the gear 205 fixed to the outer ring of the drive rod 203. At this time, the mechanical interlock setting of the synchronous control mode is completed. Then, the drive motor 204 is started, and its output shaft drives the drive rod 203 to rotate. The small pulley 206 drives the large pulley 212 to rotate via the transmission belt 207. The large pulley 212 drives the force rod 701 to rotate via the shaft of the force rod 701. The two ends of the force rod 701 are connected to a hollow plate 702 and a solid plate 703, respectively. When the force rod 701 rotates, the hollow plate 702, which was originally connected to the through hole 8, gradually rotates away, while the solid plate 703 rotates to fit against the through hole 8, thus sealing the air duct. At the same time, the gear 205 on the outer ring of the drive rod 203 drives the meshed gear 211 to rotate, thereby driving the drive rod 209 to rotate in the opposite direction. The small pulley 206 on its outer ring rotates in the same direction. The transmission belt 207 drives the large pulley 212 and the force rod 701 on the other side to rotate, causing the hollow plate 702 on that side to rotate until it aligns with the through hole 8, restoring the air duct connection. This achieves the synchronous switching action of closing one air duct while opening the other. When it is necessary to control the two air ducts independently, the handle 402 is rotated in the opposite direction, causing the screw sleeve 403 to drive the vertical rod 404 and the outer frame 210 to reset. The gear 211 disengages from the gear 1 205. At this time, the two drive motors 204 can work independently, controlling the drive rod 1 203 and drive rod 209 on both sides respectively, thereby achieving individual adjustment of the two air ducts.

[0035] This solution effectively solves the problems of insufficient cooling coverage, vacuum periods during switching, turbulent airflow, and equipment damage caused by asynchronous duct switching in existing grain depot air conditioning systems. By incorporating a force-bearing rod 701, hollow plate 702, and solid plate 703 in the duct switching mechanism 7, reliable opening and closing control of the ducts is achieved. The hollow plate 702 allows airflow while the solid plate 703 provides a seal, resulting in a simple structure with good sealing performance. In the drive mechanism 2, dual-output linkage is achieved through the meshing of gear 1 205 and gear 2 211. Combined with the transmission structure of the small pulley 206, transmission belt 207, and large pulley 212, the synchronicity and coordination of the duct switching actions on both sides are ensured. This avoids the simultaneous closure of ducts due to time differences in traditional step-by-step operations, thereby eliminating the risks of wind pressure accumulation and airflow impact, protecting the dual condenser fans 3 and the duct structure, and extending the lifespan of the system. The adjustment structure, consisting of the handle 402, lead screw, screw sleeve 403, vertical rod 404, and outer frame 210 in the docking mechanism 4, enables manual switching of gear meshing states, allowing the equipment to flexibly switch between synchronous and independent modes to meet the control requirements under different working conditions. The protective shell 5 effectively protects the transmission components, reducing the impact of dust and moisture on the transmission belt 207 and pulley, and improving operational stability. The overall structure achieves smooth and synchronous switching of the air duct through mechanical linkage, with rapid response and simple operation, reducing the frequency of manual intervention, improving the automation level of grain depot temperature control, ensuring that different areas of the grain pile can obtain accurate and uniform cooling according to actual temperature requirements, effectively preventing surface mold and deep heat core problems, improving the safety and quality stability of grain storage, and avoiding additional energy consumption caused by airflow turbulence.

[0036] When the temperature at the grain core is abnormally high, the dual condenser fans 3 will transmit cold air to the through holes 8 corresponding to their output ends.

[0037] Example 2: This example is basically the same as the previous example, except that one side of the mounting box 201 is fixedly connected to one side of the adjacent air conditioning cooling unit housing 1, and one side of the mounting box 201 is rotatably connected to the door panel 202 via a hinge, and one side of the door panel 202 is fixedly connected to a handle.

[0038] An air outlet pipe 6 is fixedly connected to one side of the protective shell 5. The inner cavity of the air outlet pipe 6 is connected to the inner cavity of the corresponding protective shell 5. The inner cavity of the protective shell 5 is connected to the inner cavity of the corresponding through hole 8. The two output ends of the dual condenser fan 3 are respectively adapted to the adjacent through holes 8.

[0039] Both sides of the outer wall of the mounting box 201 are fixedly connected to drive motors 204. One end of drive rod 1 203 is rotatably connected to the inner wall of the mounting box 201 via a rotating shaft. One end of drive rod 209 is rotatably connected to the inner wall of the mounting box 201 via a rotating shaft. The other end of drive rod 1 203 is fixedly connected to the output shaft of the corresponding drive motor 204. The other end of drive rod 209 is fixedly connected to the output shaft of the corresponding drive motor 204.

[0040] The outer rings of drive rod 1 203 and drive rod 2 209 are respectively fitted with gear 1 205 and gear 2 211, and the outer rings of gear 1 205 and gear 2 211 are connected by meshing teeth.

[0041] As can be seen from the above, by passing through the side wall of the air conditioning cooling unit housing 1 via a bushing and being fixedly connected to the large pulley 212, and by the arrangement of the solid plate 703 and the hollow plate 702 fitting against the side wall of the housing, the hollow plate 702 can accurately align with the through hole 8 to achieve conduction during the rotation of the force rod 701, while the solid plate 703 reliably blocks the through hole 8. This achieves stable air duct switching action, accurate positioning, and good sealing, effectively preventing air leakage and improving airflow control efficiency. The mounting box 201 is fixedly connected to the air conditioning cooling unit housing 1, and the mounting box 201 is connected to the door panel 202 via a hinge. The door panel 202 is equipped with a handle, which facilitates the opening and closing of the mounting box 201. This allows for convenient daily maintenance, inspection, and debugging of the internal drive motor 204, drive rod one 203, drive rod two 209, and other transmission components, improving the maintainability and operability of the equipment. For ease of use, the air outlet duct 6 is connected to the protective shell 5, and the inner cavity of the air outlet duct 6 is connected to the inner cavity of the protective shell 5 and the through hole 8. The output end of the dual condenser fan 3 is adapted to the through hole 8. When the fan is running, the airflow enters the protective shell 5 through the through hole 8 and is directly introduced into the air outlet duct 6, achieving the effect of continuous airflow channel, low wind resistance, and high delivery efficiency. At the same time, it ensures that the cold air is accurately guided to the external air supply duct, ensuring the continuity and stability of the cooling operation. The drive motor 204 is set on the outer wall of the mounting box 201. The drive rod 1 203 and drive rod 2 209 are connected to the inner wall of the mounting box 201 through a rotating shaft, and their other ends are fixedly connected to the output shaft of the drive motor 204. This realizes that the power of the drive motor 204 is directly transmitted to the drive rod, achieving the effect of short transmission path, compact structure, and stable operation. It ensures that the drive rod 1 203 and drive rod 2 209 can rotate stably, providing reliable power input for subsequent belt drive.

[0042] Example 3: This example is basically the same as the previous example, except that the outer ring of the drive rod 203 is fixedly connected to the inner wall of the gear 205, the outer ring of the drive rod 209 is fitted with a bearing sleeve, and the outer ring of the bearing sleeve is fitted with an outer frame 210. The gear 211 is located in the inner cavity of the outer frame 210, and the inner wall of the gear 211 is fixedly connected to the outer ring of the bearing sleeve.

[0043] A docking mechanism 4 is provided below the mounting box 201. The docking mechanism 4 includes a structural box 401. A lead screw is horizontally arranged in the inner cavity of the structural box 401, and a threaded sleeve 403 is sleeved on the outer ring of the lead screw. A vertical rod 404 is fixedly connected to one side of the outer ring of the threaded sleeve 403. One end of the vertical rod 404 is fixedly connected to one side of the adjacent outer frame 210.

[0044] One end of the lead screw is rotatably connected to the inner wall of the adjacent structural box 401 via a rotating shaft, and the other end of the lead screw is fixedly connected to a handle 402 through a bushing passing through the side wall of the adjacent structural box 401.

[0045] A sliding groove is provided on one side of the inner wall of the structural box 401, and a slider is fixedly connected to the other side of the screw sleeve 403, with one end of the slider slidably connected to the inner cavity of the sliding groove.

[0046] As can be seen from the above, the drive rod 203 has a gear 205 on its outer ring, and the drive rod 209 has a gear 211 on its outer ring. The two are connected by a meshing gear. When the drive rod 203 rotates, the gear meshing can drive the drive rod 209 to rotate synchronously in the opposite direction, achieving the effect of dual drive rod linkage output. This provides a mechanical basis for the synchronous reverse action of the two air duct switching mechanisms 7, improving the switching coordination. The gear 205 is fixedly connected to the drive rod 203, and the drive rod 209 has a bearing sleeve on its outer ring. The outer ring of the bearing sleeve is connected to the outer frame 210. The gear 211 is fixed to the outer ring of the bearing sleeve and located inside the outer frame 210. This allows the gear 211 to move laterally with the outer frame 210, achieving the effect of the gear 211 being able to disengage from or engage with the gear 205. This enables flexible switching between synchronous mode and independent control mode, improving the equipment's adaptability to operating conditions. By setting up a structure box 401, lead screw, and screw sleeve 40 below the mounting box 201, the gear 211 can achieve the effect of disengaging from or engaging with the gear 205. 3. The docking mechanism 4 of the vertical rod 404 and the setting of the vertical rod 404 connecting to the outer frame 210, when the lead screw is rotated, the screw sleeve 403 drives the vertical rod 404 and the outer frame 210 to move, achieving the effect of precisely controlling the lateral displacement of the gear 211, thereby realizing the reliable switching of the gear meshing state. The structure is stable and the operation is precise. The lead screw is rotatably connected to the inner wall of the structure box 401 at one end, and the other end passes through the box body through the bushing and is connected to the handle 402. The operator can rotate the handle 402 to drive the lead screw to rotate, thereby driving the screw sleeve 403 to move linearly, achieving the effect of manually adjusting the gear meshing position. The operation is intuitive and labor-saving, and it is convenient to quickly switch the control mode on site. The inner wall of the structure box 401 is provided with a sliding groove, and the screw sleeve 403 is connected to the slider. The slider slides in the sliding groove, which effectively limits the movement path of the screw sleeve 403, achieving the effect of preventing the screw sleeve 403 from rotating with the lead screw and ensuring that it only moves in a linear motion, improving the transmission accuracy and the reliability of the mechanism operation, and avoiding jamming or deviation.
