Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 The present invention provides the following technical solution:

[0030] A detachable agricultural machinery circuit board includes a circuit board body 1, a fixing structure 2, a heat dissipation structure 3, and a connecting plate 4. The circuit board body 1 is installed inside the fixing structure 2. The heat dissipation structure 3 is connected to the bottom outer side of the fixing structure 2 through the connecting plate 4 and screws. A mounting frame 5 is connected to the bottom outer side of the heat dissipation structure 3.

[0031] like Figures 1-5As shown, the fixing structure 2 includes a fixing frame 201, a spring 202, a pressure plate 203, and a fixing plate 204. First, the pressure plates 203 on the left and right sides are pushed upward, and at the same time, the circuit board body 1 is pushed in from the front. Then, the pressure plate 203 on the rear side is pushed upward, and at the same time, the circuit board body 1 continues to be pushed to the rear side, until it is below the pressure plate 203 on the rear side. One end of the spring 202 is fixedly connected to the inner side of the top of the fixing frame 201, and the end of the spring 202 away from the fixing frame 201 is fixedly connected to the pressure plate 203. The pressure plates 203 on the left and right sides and the pressure plate 203 on the rear side are fixed to the circuit board body 1 by the spring 202.

[0032] The fixing plate 204 is an L-shaped plate. The fixing plate 204 is installed on the front side of the circuit board body 1. The horizontal plate of the fixing plate 204 presses against the top of the circuit board body 1, and the vertical plate of the fixing plate 204 abuts against the front side of the circuit board body 1. The fixing plate 204 is fixedly connected to the fixing frame 201 using screws.

[0033] like Figures 2-4 and Figure 6 As shown, the heat dissipation structure 3 includes a heat dissipation fan 301, heat dissipation fins 302, a filter plate 303, and a connecting shell 304. The filter plate 303, heat dissipation fins 302, and heat dissipation fan 301 are fixedly installed inside the connecting shell 304 from bottom to top. When the heat dissipation fan 301 is turned on, it blows air onto the bottom wall of the fixing frame 201, thereby cooling the circuit board body 1. The heat dissipation fins 302 can increase the heat dissipation area and improve the heat dissipation efficiency. The bottom wall of the fixing frame 201 is hollow, which further improves the heat dissipation efficiency.

[0034] The top outer side of the connecting shell 304 is fixedly connected to the fixing frame 201 by the connecting plate 4 and screws, thereby fixing the heat dissipation structure 3 to the bottom of the fixing structure 2. At the same time, the two structures can be disassembled by unscrewing the screws in the connecting plate 4.

[0035] A mounting frame 5 is fixedly connected to the bottom outer side of the connecting shell 304, through which the detachable agricultural machinery circuit board can be installed inside the agricultural machinery.
