Description

Technical Field

[0001] This utility model relates to the field of harvester technology, specifically to a harvester canopy structure that facilitates heat insulation. Background Technology

[0002] Harvesters face the challenge of high temperatures and heat during farmland operations, especially in summer. Existing harvester canopies are usually made of metal or plastic materials, which heat up rapidly under sunlight, causing the temperature inside the driver's cabin to rise rapidly. Working in high-temperature environments for extended periods can easily lead to fatigue, dizziness, and even heatstroke in severe cases. Most existing harvester designs prioritize functionality over comfort, resulting in poor heat insulation in the canopy. This not only increases the driver's workload but may also affect the driver's health and work efficiency.

[0003] According to a heat insulation device for the canopy of a harvester (Announcement No.: CN222603105U), the above application uses heat insulation cotton to effectively isolate the indoor and outdoor temperatures, and a reflective layer to effectively reflect the heat from direct sunlight, further improving the heat insulation effect. The setting of the through-channel effectively reduces the heat conduction effect of solar radiation, and keeps the machine room warm, effectively improving the heat insulation effect of the canopy, which is beneficial to the health of the driver and the improvement of work efficiency.

[0004] However, in actual use, the above-mentioned equipment only passively isolates the outdoor temperature by setting up simple heat insulation materials such as heat insulation cotton and reflective layer, without setting up any active cooling device; in view of this, we propose a harvester canopy structure that is easy to insulate. Summary of the Invention

[0005] The purpose of this invention is to provide a harvester canopy structure that is easy to insulate, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A harvester canopy structure with easy heat insulation includes a machine compartment, a canopy is fixedly connected to the upper surface of the machine compartment, a heat insulation board is fixedly connected to the upper surface of the canopy, and a cooling mechanism is provided on the upper surface of the heat insulation board, the cooling mechanism including:

[0007] The mounting shell has its bottom surface fixedly connected to the top surface of the heat insulation board. An air inlet is provided on the side wall of the mounting shell. A motor is fixedly connected to the top surface inside the mounting shell. A fan blade is fixedly connected to the output end of the motor. A circular through groove is provided between the mounting shell and the ceiling.

[0008] The clamping component has a fixed end that is fixedly connected to both sides of the interior of the ceiling. The clamping end of the clamping component holds a cooling radiator. One end of the cooling radiator is fixedly connected to a connecting pipe. The other end of the connecting pipe is fixedly connected to a pump. The output end of the pump is fixedly connected to a liquid storage tank. The end of the liquid storage tank away from the machine compartment is provided with heat dissipation fins.

[0009] Preferably, a guide plate is fixedly connected between the side wall of the liquid storage tank and the top of the machine compartment, the pump is located in the space formed between the guide plate, the top of the machine compartment, and the liquid storage tank, and an air outlet is provided on the lower surface of the machine compartment.

[0010] Preferably, the radiator is U-shaped and is a certain distance from the inner bottom surface of the ceiling. The radiator is fixedly connected to the liquid storage tank and the pump via connecting pipes.

[0011] Preferably, the interior of the ceiling is provided with an auxiliary mechanism, which includes a waterproof platform. The lower surface of the waterproof platform is fixedly connected to the interior bottom surface of the ceiling. The interior of the waterproof platform has a ventilation groove that penetrates through itself and the bottom surface of the ceiling. A filter plate is fixedly connected to the side wall of the ventilation groove. A drain outlet is provided on the side wall of the ceiling.

[0013] Preferably, the waterproof platform is located at the vertical end of the radiator, and the height of the waterproof platform does not exceed the radius of the radiator.

[0014] Preferably, the drain outlet is located at the lowest point inside the ceiling.

[0015] Compared with the prior art, this utility model provides a harvester canopy structure that is easy to insulate, and has the following beneficial effects:

[0016] 1. This harvester canopy structure, which facilitates heat insulation, incorporates a cooling mechanism. External air is drawn in through air inlets on the side wall of the mounting shell, and a motor-driven fan forces the airflow through a circular channel into the canopy. Simultaneously, a U-shaped radiator, secured by clamps, absorbs heat and dissipates low temperatures. The radiator is connected to a pump and a coolant tank via connecting pipes, forming a coolant circulation system. The coolant dissipates heat at the cooling fins at the end of the coolant tank, and hot air is guided by a guide vane to exit through the air outlet on the lower surface of the machine compartment. This achieves active cooling of the canopy, effectively reducing heat accumulation and improving insulation performance, ensuring a stable internal temperature for the machine compartment.

[0017] 2. This harvester canopy structure, which facilitates heat insulation, is equipped with auxiliary mechanisms and a waterproof platform to prevent moisture from seeping into the machine compartment. Its ventilation slots ensure the circulation of cold air, and the filter plates on the side walls of the ventilation slots can block dust and impurities. The bottom surface of the canopy is designed to be sloping, lower near the liquid storage tank and higher away from the liquid storage tank. Combined with the drain outlet located at the lowest point and the screen plate on the inner wall, it is easy to automatically collect and discharge dirt, avoiding blockage or corrosion of components. At the same time, the height of the waterproof platform is controlled within the radius of the radiator to ensure that the radiator is protected, thereby improving the durability and cleaning efficiency of the overall structure.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a harvester canopy structure that facilitates heat insulation, including a machine compartment 1, a canopy 11 fixedly connected to the upper surface of the machine compartment 1, a heat insulation plate 12 fixedly connected to the upper surface of the canopy 11, and a cooling mechanism 2 provided on the upper surface of the heat insulation plate 12. The cooling mechanism 2 includes: a mounting shell 21, an air inlet 22, a motor 23, a fan blade 24, a clamping component 25, a cooling radiator 26, a connecting pipe 27, a pump 28, a liquid storage tank 29, heat dissipation fins 210, an air guide plate 211, and an air outlet 212.

[0025] In one embodiment of this utility model, the bottom surface of the mounting shell 21 is fixedly connected to the top surface of the heat insulation plate 12. An air inlet 22 is provided on the side wall of the mounting shell 21. A motor 23 is fixedly connected to the inner top surface of the mounting shell 21. A fan blade 24 is fixedly connected to the output end of the motor 23. A circular through-slot is provided between the mounting shell 21 and the ceiling 11. The airflow generated by the motor 23 driving the fan blade 24 can be blown into the interior of the ceiling 11 through the circular through-slot. The fixed end of the clamping member 25 is connected to the interior of the ceiling 11. The cooling radiator 26 is fixedly connected to the side, and the clamping end of the clamping member 25 clamps the cooling radiator 26, providing sufficient support for the cooling radiator 26. One end of the cooling radiator 26 is fixedly connected to a connecting pipe 27, and the other end of the connecting pipe 27 is fixedly connected to a pump 28. The output end of the pump 28 is fixedly connected to a liquid storage tank 29. The cooling radiator 26 is connected to the pump 28 and the liquid storage tank 29 through the connecting pipe 27 to form a coolant circulation system. The end of the liquid storage tank 29 away from the engine compartment 1 is provided with heat dissipation fins 210, and the coolant circulates within the tank. The heat dissipation fins 210 at the end of the liquid storage tank 29 provide heat dissipation. A guide plate 211 is fixedly connected between the side wall of the liquid storage tank 29 and the top of the machine compartment 1. The guide plate 211 prevents cold air from blowing directly onto the head of the staff, thus preventing any impact on their health. The pump 28 is located in the space formed between the guide plate 211, the top of the machine compartment 1, and the liquid storage tank 29. By placing the pump 28 inside the guide plate 211, heat dissipation for the staff can be achieved while maintaining the heat dissipation effect of the pump 28. An air outlet 212 is provided on the lower surface of the housing 1. The air outlet 212 and the air inlet 22 form a heat dissipation air channel, which effectively reduces heat accumulation and improves heat insulation performance, ensuring stable internal temperature of the housing 1. The radiator 26 is U-shaped. The U-shaped radiator 26 has a larger heat dissipation area and better heat dissipation effect. The radiator 26 is a certain distance away from the inner bottom surface of the roof 11. The radiator 26 is fixedly connected to the liquid storage tank 29 and the pump 28 through the connecting pipe 27.

[0026] In addition, an auxiliary mechanism 3 is provided inside the canopy 11. The auxiliary mechanism 3 includes a waterproof platform 31. The lower surface of the waterproof platform 31 is fixedly connected to the inner bottom surface of the canopy 11. A ventilation groove is opened inside the waterproof platform 31, penetrating itself and the bottom surface of the canopy 11. A filter plate 32 is fixedly connected to the side wall of the ventilation groove. A drain outlet 33 is opened on the side wall of the canopy 11. The inner bottom surface of the canopy 11 is set to be low near the liquid storage tank 29 and high away from the liquid storage tank 29. A sieve plate is fixedly connected to the inner wall of the drain outlet 33. By setting up the auxiliary mechanism 3, in conjunction with the waterproof platform 31, moisture is prevented from seeping into the machine compartment 1. The ventilation groove ensures the circulation of cold air. The filter plate 32 on the side wall of the ventilation groove can block dust and impurities while dispersing the strong cold air, turning it into a gentle breeze.

[0027] In this embodiment of the utility model, the inner bottom surface of the canopy 11 is designed to be low near the liquid storage tank 29 and high away from the liquid storage tank 29. A sieve plate is fixedly connected to the inner wall of the drain outlet 33. The waterproof platform 31 is set at the vertical end of the radiator 26. The height of the waterproof platform 31 does not exceed the radius of the radiator 26. The drain outlet 33 is opened at the lowest point inside the canopy 11. The inner bottom surface of the canopy 11 is designed to be inclined, low near the liquid storage tank 29 and high away from the liquid storage tank 29. With the drain outlet 33 opened at the lowest point and the sieve plate on the inner wall, it is convenient to automatically collect and discharge dirt. At the same time, the height of the waterproof platform 31 is controlled within the radius of the radiator 26. The height of the waterproof platform 31 ensures that the interior of the machine compartment 1 will not be soaked by condensate water without hindering the downward flow of cold air, ensuring that the radiator 26 is protected and improving the durability and cleaning efficiency of the overall structure.

[0028] In this invention, during use, the motor 23 drives the fan blades 24 to rotate, drawing in external air through the air inlet 22 on the side wall of the mounting housing 21. The airflow passes downward through the circular groove between the mounting housing 21 and the ceiling 11, entering the internal space of the ceiling 11. Within this space, coolant circulates inside the U-shaped radiator 26, which is fixed by the clamping member 25. The pump 28 pumps the coolant from the storage tank 29 into the radiator 26 through the connecting pipe 27. The airflow flowing over the surface of the radiator 26 exchanges heat with the coolant, carrying away the heat accumulated in the ceiling 11, thus forming a cooling effect. The airflow that absorbs heat and heats up then flows back to the storage tank 29 through the connecting pipe 27, and is cooled by the heat dissipation fins 210 at the end of the storage tank 29. The air guide plate 211 guides part of the airflow through the heat dissipation fins 210 to enhance the heat dissipation effect. Finally, the airflow carrying heat is discharged from the air outlet 212 at the bottom of the machine compartment 1. At the same time, the waterproof platform 31 of the auxiliary mechanism 3 and its internal ventilation slot (with filter plate 32) ensure air circulation and block debris. The bottom surface of the roof 11 is designed to slope towards the drain outlet 33 to facilitate the discharge of any liquids or dirt that may enter.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
