[0027] The top of the equipment rack 701 is provided with a swing mechanism 9, the swing mechanism 9 includes an equipment box 901, the equipment box 901 is fixedly installed on the top surface of the equipment rack 701, the other end output shaft of the double-shaft motor 705 extends to the inside of the equipment box 901, and is fixedly connected with a gear one 902, the inside of the equipment box 901 is rotatably installed with a transmission shaft 903, the gear one 902 and the transmission shaft 903 are mutually engaged, one end of the transmission shaft 903 is fixedly sleeved with a turntable 905, the inside of the turntable 905 is provided with a special-shaped groove 910, the top surface of the equipment rack 701 is fixedly installed with a stand 906, the inside of the stand 906 is rotatably installed with a positioning pin 907, the outer surface of the positioning pin 907 is fixedly sleeved with a swing frame 908, one end of the swing frame 908 is installed with a clamping frame 909, for limiting and fixing the heat supply pipe 703, the other end of the swing frame 908 is fixedly installed with a protruding block 911, the protruding block 911 is clamped in the inside of the special-shaped groove 910.

[0028] When the double-shaft motor 705 rotates, the gear one 902 can also be driven to rotate synchronously, because the gear one 902 and the gear two 904 are mutually engaged, the transmission shaft 903 can be driven to rotate, so that the turntable 905 rotates outside the equipment box 901, because one end of the swing frame 908 is clamped in the inside of the special-shaped groove 910 through the protruding block 911, the swing frame 908 can be driven to swing up and down at one end of the special-shaped groove 910, and because one end of the heat supply pipe 703 is limited at one end of the swing frame 908 through the clamping frame 909, the heat supply pipe 703 can be driven to swing up and down synchronously when one end of the swing frame 908 swings up and down, so that the purpose of further improving the uniformity of the heat supply in the greenhouse is realized, and when the swing frame 908 drives the heat supply pipe 703 to move upward to the highest position, the clamping frame 909 can be aligned with the inside bottom surface of the film 2 to spray, because the inside bottom surface of the film 2 is a circular arc, the hot air blown out by the heat supply pipe 703 can move to both sides along the inside bottom surface of the film 2, thereby improving the uniformity of the heat supply of the heat supply mechanism 7 again.

[0029] Specifically, the working process or working principle of the heating device for agricultural greenhouse is as follows: in use, the double-shaft motor 705 is started to drive the fixed disc 707 and the external disc 708 to rotate, thereby driving the air inlet blade 709 to rotate rapidly.

The driving motor 803 is started to drive the pulley one 804, the pulley two 806 and the transmission belt 807 to drive the rotating shaft 805 to rotate, thereby driving the roller 808 to rotate, so that the moving frame 802 can move along the guide rail frame 801. Since the equipment frame 701 is fixedly installed on the top of the moving frame 802, when the moving frame 802 moves, the equipment frame 701 can be driven to move synchronously, thereby changing the position of the heating mechanism 7 as a whole, realizing more uniform heating of the inside of the greenhouse, thereby achieving the purpose of making the heating of the heating mechanism 7 more uniform. When the double-shaft motor 705 rotates, the gear one 902 can also be driven to rotate synchronously. Since the gear one 902 and the gear two 904 are engaged with each other, the transmission shaft 903 can be driven to rotate, so that the rotating disc 905 rotates outside the equipment box 901. Since one end of the swing frame 908 is clamped in the special-shaped groove 910 by the protrusion 911, the one end of the swing frame 908 can be driven to swing up and down under the action of the special-shaped groove 910. Since one end of the heating pipe 703 is limited by the swing frame 908 through the clamp frame 909, the heating pipe 703 can be driven to swing up and down synchronously when the one end of the swing frame 908 swings up and down, thereby achieving the purpose of further improving the uniformity of heating in the greenhouse.

[0030] It should be noted that the double-shaft motor 705, the driving motor 803 and the touch switch 810 are devices or equipment existing in the prior art or devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, and therefore will not be described in detail.
