DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer toFigures 1-4 , the present utility model provides a technical solution: a harvester air conditioner with an energy-saving structure. A harvester air conditioner 2 is installed on the top of the harvester cockpit 1 to regulate the temperature of the harvester cockpit 1 and create good working conditions for the driver.

[0025] Specifically, the harvester air conditioner 2 includes a protective cover 201, and a high-efficiency air conditioning system 3 is arranged inside the protective cover 201. The protective cover 201 can play a certain protective role for the high-efficiency air conditioning system 3. The high-efficiency air conditioning system 3 includes a mounting base 301, and a blower box 302, an air compressor 303 and a condenser 304 are sequentially installed on the mounting base 301.

[0026] Specifically, the air inlet of the blower box 302 penetrates to the outside of the protective cover 201, and a high-efficiency energy-saving driving fan blade is installed inside the blower box 302. The high-efficiency energy-saving driving fan blade includes a driving motor 3031, and the output end of the driving motor 3031 drives a first gear 3033 to rotate through a driving rod 3032. The first gear 3033 meshes with a second gear 3034, and the second gear 3034 is installed on the outside of a first rotating rod 3035. A third gear 3036 is arranged on the outside of the first rotating rod 3035, and the third gear 3036 meshes with a fourth gear 3037. The fourth gear 3037 is installed on the outside of a second rotating rod 3038, and fan blades 3039 are symmetrically installed on the outside of the second rotating rod 3038. The first rotating rod 3035 and the second rotating rod 3038 are rotatably connected to the inside of the blower box 302.

[0027] In a further embodiment, a dust-proof filter screen 3021 is installed inside the air inlet of the blower box 302. The dust-proof filter screen 3021 can prevent dust and foreign objects from entering the inside of the blower box 302.

[0028] Specifically, the size of the second gear 3034 is smaller than that of the first gear 3033. Therefore, when the first gear 3033 rotates, it can drive the second gear 3034 to rotate at an accelerated speed. The size of the fourth gear 3037 is smaller than that of the third gear 3036. Therefore, when the third gear 3036 rotates, it can drive the fourth gear 3037 to rotate at an accelerated speed.

[0029] When it is necessary to drive the fan blade 3039 to rotate so as to suck external air, the driving motor 3031 is turned on. The output end of the driving motor 3031 drives the first gear 3033 to rotate through the driving rod 3032. The first gear 3033 can drive the second gear 3034 and the first rotating rod 3035 to rotate at an accelerated speed. The first rotating rod 3035 drives the third gear 3036 to rotate synchronously. The third gear 3036 can drive the fourth gear 3037 and the second rotating rod 3038 to rotate at an accelerated speed. Thus, the fan blade 3039 is driven to rotate through the second rotating rod 3038 so as to suck external air. The first gear 3033, the second gear 3034, the third gear 3036 and the fourth gear 3037 can accelerate the transmission of the rotational speed of the driving motor 3031. Thus, the rotational speed of the fan blade 3039 is increased and the efficiency is improved under the condition of the same power, achieving an energy-saving effect.

[0030] Specifically, the fan box 302, the air compressor 303 and the condenser 304 are connected through pipelines. One end of the condenser 304 is connected to the middle of the upper end of the exhaust air plate 306 through the first air supply pipe 305 penetrating through the installation base 301. And both sides of the upper end of the exhaust air plate 306 are connected to both sides of the lower end of the installation base 301 through the connecting rods 307. The steam generator 308 is installed in the middle of the back of the condenser 304. And one end of the steam generator 308 is connected to the air compressor 303 through a pipeline. The other end of the steam generator 308 is connected to the middle of the upper end of the exhaust air plate 306 at the rear through the second air supply pipe 309 penetrating through the installation base 301.

[0031] The external air is sucked by the fan box 302, then compressed by the air compressor 303 and enters the condenser 304 for condensation, and then is transported to the exhaust air plate 306 through the first air supply pipe 305 for discharge, so as to achieve refrigeration. The steam generator 308 is installed in the middle of the back of the condenser 304. And one end of the steam generator 308 is connected to the air compressor 303 through a pipeline. At the same time, the other end of the steam generator 308 is connected to the middle of the upper end of the exhaust air plate 306 at the rear through the second air supply pipe 309 penetrating through the installation base 301. The external air is sucked by the fan box 302, then compressed by the air compressor 303 and enters the steam generator 308 for heating, and then is transported to the exhaust air plate 306 through the second air supply pipe 309 for discharge, so as to achieve heating.
