[0026] The solar-powered chestnut drying equipment includes: a drying box 1 with a solar panel 2 fixedly installed on the top; a drive gear shaft 3, which is rotatably installed inside the drying box 1; a synchronous toothed belt 4, which is sleeved on the drive gear shaft 3 and fixedly installed with a support block 5; a holding tray 6, which is used to hold chestnuts and is arranged between the synchronous toothed belts 4 and in contact with the support block 5; a hot air pipe 7, which is fixedly installed on the drying box 1 and used to introduce hot air into the drying box 1; an exhaust pipe 8, which is fixedly installed on the hot air pipe 7 and extends into the drying box 1, wherein multiple exhaust pipes 8 are provided and evenly distributed longitudinally on the drying box 1, and a hot air guiding mechanism is provided on the exhaust pipe 8; and an exhaust pipe 9, which is fixedly installed on the top of the drying box 1 and used to discharge excess water vapor inside the drying box 1. Solar panel 2 absorbs solar energy and converts it into electricity or other usable energy to power the equipment, enabling chestnut drying using renewable energy, reducing reliance on traditional energy sources, lowering production costs, and reducing greenhouse gas and other harmful gas emissions, thus benefiting environmental protection. A motor drives a drive gear shaft 3, which in turn drives a synchronous toothed belt 4, causing the support block 5 to move the tray 6 containing chestnuts, facilitating the placement and removal of the tray and ensuring the continuity of the drying process. Hot air duct 7 introduces hot air into the drying chamber 1, providing the necessary heat for chestnut drying. Multiple exhaust ducts 8 are evenly distributed longitudinally on the drying chamber 1, and each exhaust duct 8 is equipped with a hot air guiding mechanism. This design allows for more even distribution of hot air within the drying chamber 1, preventing uneven heating of chestnuts due to concentrated hot air outlets, reducing shell cracking and browning, and ensuring the product's appearance and taste. Exhaust pipe 9 removes excess moisture from the drying chamber 1, maintaining a suitable drying environment and improving drying efficiency and quality.
[0027] The hot air guiding mechanism includes a guide plate 10, a connecting port 11, a synchronizing rod 12, a connecting rod 13, a docking frame 14, and a driving mechanism. The connecting port 11 is located on the drying chamber 1. The guide plate 10 is hinged within the connecting port 11 and extends outside the drying chamber 1. The synchronizing rod 12 is hinged to the portion of the guide plate 10 extending outside the drying chamber 1. The connecting rod 13 is hinged to the synchronizing rod 12. The docking frame 14 is slidably mounted on the drying chamber 1 and is hinged to the other end of the connecting rod 13. The driving mechanism is located on the drying chamber 1 and is used to drive the guide plate 10 to reciprocate. The connecting port 11 provides a spatial channel for the installation and movement of the guide plate 10, allowing the hot air guiding mechanism to communicate with the interior of the drying chamber 1, thereby controlling the direction of the hot air flow. The guide plate 10 is a component that directly changes the direction of hot air flow. Its rotation within the connecting port 11 adjusts the distribution direction of the hot air discharged from the exhaust pipe 8 within the drying chamber 1, thereby improving the uniformity of heating the chestnuts. The synchronizing rod 12 transmits motion, connecting the movement of multiple guide plates 10 with the subsequent connecting rod 13, ensuring synchronized rotation of the guide plates 10. The connecting rod 13 is an intermediate component for motion transmission, further transmitting the motion of the synchronizing rod 12 to the docking frame 14, realizing force transmission and motion conversion. The sliding movement of the docking frame 14 provides support and guidance for the entire hot air guiding mechanism. Simultaneously, it receives the motion transmitted from the connecting rod 13 and connects this motion to the drive mechanism, ensuring that the entire hot air guiding mechanism moves according to the instructions of the drive mechanism. The drive mechanism is the power source of the entire hot air guiding mechanism. Through its operation, the docking frame 14 can slide, thereby driving the connecting rod 13 and the synchronizing rod 12 to move, and finally realize the reciprocating rotation of the guide plate 10, thereby periodically changing the flow direction of hot air in the drying box 1, so that the chestnuts are heated more evenly.
[0028] The driving mechanism includes a drive plate 15, a rotary motor 16, a protrusion 17, and a reset mechanism. The drive plate 15 is fixedly mounted on the docking frame 14, the rotary motor 16 is fixedly mounted on the drying chamber 1, the protrusion 17 is fixedly mounted on the output shaft of the rotary motor 16, and the reset mechanism is located on the drying chamber 1 to drive the docking frame 14 to reset. The drive plate 15 serves as an intermediate transmission component between the driving action of the rotary motor 16 and the docking frame 14. The power output by the rotary motor 16 is transmitted to the docking frame 14 through interaction with the drive plate 15, thereby driving the entire hot air guiding mechanism to move. The rotary motor 16 is the power source of the driving mechanism, providing driving force to the entire driving mechanism through its own rotational motion. Its speed and direction can be adjusted by the control system to meet the hot air guiding requirements of different drying stages. When the rotary motor 16 is running, the protrusion 17 will rotate accordingly. During the rotation, the protrusion 17 will periodically contact and push the drive plate 15, thereby causing the docking frame 14 to slide and realizing the movement of the guide plate 10. When the protrusion 17 disengages from the drive plate 15, the reset mechanism takes effect, causing the docking frame 14 to return to its initial position, preparing for the next push of the protrusion 17. This process is repeated to achieve the reciprocating motion of the guide plate 10.
[0029] The reset mechanism includes a support plate 18, a fixing block 19, and a spring 20. The support plate 18 is fixedly mounted on the drive plate 15, the fixing block 19 is fixedly mounted on the drying chamber 1, and the spring 20 is fixedly mounted between the support plate 18 and the fixing block 19. The support plate 18 serves as a connecting bridge between the spring 20 and the drive plate 15. When the drive plate 15 is pushed by the protrusion 17, the support plate 18 moves accordingly, thereby causing the spring 20 to deform. When the protrusion 17 disengages from the drive plate 15, the support plate 18 can use the elastic force of the spring 20 to reset the drive plate 15. The fixing block 19 provides a stable fixed support point for the spring 20, ensuring that the spring 20 remains relatively fixed in position during deformation and restoration, thus ensuring the normal operation of the reset mechanism. When the protrusion 17 pushes the drive plate 15 to move, the support plate 18 compresses the spring 20, causing the spring 20 to store elastic potential energy. When the protrusion 17 disengages from the drive plate 15, the spring 20 releases the stored elastic potential energy, pushing the support plate 18 and the drive plate 15 back to their initial positions, thus resetting the docking frame 14 and driving the guide plate 10 to complete one reciprocating motion.
[0030] A stabilizing rod 21 is fixedly installed between the synchronizing rods 12. The stabilizing rod 21 is positioned above the hot air duct 7 but does not contact it. The stabilizing rod 21 connects the two synchronizing rods 12 to form a single structure. Simultaneously, the stabilizing rod 21's position above the hot air duct 7 without contacting it ensures its effective function while avoiding interference with the hot air duct 7. When the drive mechanism drives the guide plate 10 in reciprocating motion, the synchronizing rods 12 move accordingly. The presence of the stabilizing rod 21 enhances the connection strength and overall stability between the synchronizing rods 12, preventing wobbling or deformation during movement. This ensures the guide plate 10 reciprocates according to a predetermined trajectory and frequency, thereby guaranteeing the stable and reliable operation of the hot air guiding mechanism.
[0031] Limiting blocks are fixedly installed on both sides of the support block 5. A guide groove 22 is provided on the inner wall of the drying chamber 1, and the guide groove 22 is slidably connected to the limiting blocks. The limiting block, as a connecting component between the support block 5 and the guide groove 22, has a shape and size that matches the guide groove 22, allowing it to slide along the guide groove 22. The guide groove 22 provides a track for the movement of the support block 5 and the limiting blocks. The orientation and size of the guide groove 22 are carefully designed to ensure that the support block 5 can move within the drying chamber 1 along a predetermined path. The slidable connection between the guide groove 22 and the limiting blocks allows the support block 5 to be constrained and guided by the guide groove 22 when it moves under the drive of the drive gear shaft 3 and the synchronous toothed belt 4, enabling it to move smoothly in a specific direction.
[0032] A hinged door 23 is mounted on the drying chamber 1 for retrieving the tray 6. The door 23 is positioned above the drive gear shaft 3 and the synchronous toothed belt 4. The door 23 is hinged to the drying chamber 1, allowing it to rotate around the hinge point for opening and closing. This placement of the door 23 above the drive gear shaft 3 and synchronous toothed belt 4 ensures that it does not interfere with their normal operation while facilitating the operator's handling of the tray 6. When the tray 6 needs to be retrieved or placed, the operator can open the door 23 and easily insert or remove it from the drying chamber 1 using the corresponding position on the drying chamber 1. During the drying process, the door 23 remains closed, effectively preventing heat loss from the drying chamber 1, maintaining a stable temperature, and improving drying efficiency.
[0033] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
[0034] The working principle of the solar-powered chestnut drying equipment provided by this utility model is as follows:
[0035] In use, the solar panel 2 absorbs solar energy and converts it into electrical energy, providing power to the motor and rotary motor 16 in the equipment, thus realizing the use of renewable energy for chestnut drying. The motor drives the drive gear shaft 3 to rotate. Since the synchronous toothed belt 4 is sleeved on the drive gear shaft 3, the rotation of the drive gear shaft 3 will drive the synchronous toothed belt 4 to move. A support block 5 is fixedly installed on the synchronous toothed belt 4, and the support block 5 moves along with it.
[0036] A tray 6 containing chestnuts is placed between the synchronous toothed belts 4 and comes into contact with the support block 5. As the support block 5 moves, the tray 6 moves within the drying chamber 1, facilitating the placement and removal of the tray 6 containing chestnuts and ensuring the continuity of the drying process. Limiting blocks on both sides of the support block 5 slide along guide grooves 22 on the inner wall of the drying chamber 1. This sliding connection allows the support block 5 to move smoothly in a specific direction, ensuring the stability of the tray 6's transport.
[0037] Hot air is introduced into the drying chamber 1 through the hot air duct 7 to provide the necessary heat for drying chestnuts. The rotary motor 16 starts running, and the protrusion 17 on its output shaft rotates accordingly. During rotation, the protrusion 17 periodically contacts and pushes the drive plate 15, which is fixedly mounted on the docking frame 14, thereby causing the docking frame 14 to slide. When the protrusion 17 disengages from the drive plate 15, the support plate 18 uses the elastic force of the spring 20 to reset the drive plate 15, thereby resetting the docking frame 14. This process repeats, causing the docking frame 14 to perform a reciprocating sliding motion.
[0038] The reciprocating sliding motion of the docking frame 14 is transmitted to the guide plate 10 through the connecting rod 13 and the synchronizing rod 12, causing the guide plate 10 to reciprocate. Multiple exhaust pipes 8 are evenly distributed longitudinally on the drying chamber 1. The reciprocating rotation of the guide plate 10 can periodically change the flow direction of the hot air discharged from the exhaust pipes 8 within the drying chamber 1, making the hot air more evenly distributed within the drying chamber 1. Stabilizing rods 21 are fixedly installed between the synchronizing rods 12. The stabilizing rods 21 enhance the connection strength and overall stability between the synchronizing rods 12, ensuring that the guide plate 10 can reciprocate according to a predetermined trajectory and frequency. The exhaust pipe 9 is fixedly installed on the top of the drying chamber 1 to discharge excess moisture from the drying chamber 1, maintaining a suitable drying environment within the drying chamber 1 and improving drying efficiency and quality.
[0039] When it is necessary to take out or place the tray 6, the operator can open the hinged door 23 on the drying chamber 1 and easily put the tray 6 into or take out the drying chamber 1 through the corresponding position on the drying chamber 1. During the drying process, the door 23 is in the closed state, which can effectively prevent heat loss from the drying chamber 1 and maintain a stable temperature inside the drying chamber 1.

A motor drives a drive shaft and a synchronous toothed belt, which in turn moves the support block and the tray, facilitating the loading and unloading of chestnuts, ensuring the continuity of the drying process, and improving drying efficiency.
[0042] The hot air guiding mechanism periodically changes the flow direction of hot air in the drying chamber through the reciprocating rotation of the guide plate. Combined with the longitudinally evenly distributed exhaust pipes, the hot air is more evenly distributed in the drying chamber, effectively avoiding uneven heating of chestnuts, reducing phenomena such as shell cracking and browning, and ensuring the appearance and taste of the product.
