[0023] like Figure 1~Figure 5As shown, this embodiment proposes a heating frame for agricultural planting, including a support frame 2 sleeved on the outer edge of a cultivation bed 3, a heating mechanism 4 is arranged on the inner side of the support frame 2, and the heating mechanism 4 includes a reciprocating screw rod 41, the reciprocating screw rod 41 is rotatably connected to one end of the inner side of the support frame 2, and the other end of the inner side of the support frame 2 is fixedly connected to a guide rod 42 arranged parallel to the reciprocating screw rod 41, a movable frame 44 is slidably connected to the guide rod 42, and the end of the movable frame 44 away from the guide rod 42 is threadedly connected to the reciprocating screw rod 41, and the movable frame 44 is a U-shaped structure. The length of the frame 44 is greater than the width of the cultivation bed 3, the reciprocating screw rod 41 is the same length as the guide rod 42, and the length of the guide rod 42 is greater than the length of the cultivation bed 3, a motor 43 is fixedly installed at one end of the support frame 2, the output shaft of the motor 43 is fixedly connected to the reciprocating screw rod 41, a rotating seat 45 is rotatably connected to the middle part of the inner side of the movable frame 44, and a heating component 46 for introducing heat to the cultivation bed 3 is provided at the bottom end of the rotating seat 45, and a driving component 47 is provided at one end of the movable frame 44 to drive the rotating seat 45 to reciprocate by cooperating with the translation of the movable frame 44.

[0024] By starting the motor 43 to drive the reciprocating screw 41 to rotate, the movable frame 44 can reciprocate and translate along the axial direction of the reciprocating screw 41, which makes the heating element 46 translate along the length direction of the cultivation bed 3. At the same time, the driving member 47 can drive the rotating seat 45 to rotate back and forth, and the heating element 46 follows the rotating seat 45 to reciprocate. In this way, the heating element 46 swings back and forth along the width direction of the cultivation bed 3, so that the heating element 46 cross-heats the length and width of the cultivation bed 3, and the heating element 46 can evenly heat the crops on the cultivation bed 3, which is beneficial to the normal growth of the crops.

[0025] Furthermore, the driving member 47 includes a worm wheel 471, which is coaxially fixedly connected to the rotating seat 45. A worm 472 is rotatably connected to the inner side of the movable frame 44. One end of the worm 472 is meshed with the worm wheel 471, and the other end of the worm 472 is fixedly connected to a transmission gear 473. A linkage member 48 for driving the transmission gear 473 to rotate is provided on the outer side of the movable frame 44. The linkage member 48 includes a plurality of tooth plates 481, which are all fixedly connected to one end of the top of the support frame 2, and the plurality of tooth plates 481 are equidistantly distributed along the length direction of the support frame 2.

A coil spring 482 is sleeved on the worm 472, one end of the coil spring 482 is welded to the transmission gear 473, and the other end of the coil spring 482 is welded to the movable frame 44.

[0026] The reciprocating screw rod 41 is driven to rotate by the motor 43, so that the movable frame 44 can reciprocate and translate along the axial direction of the reciprocating screw rod 41, which makes the transmission gear 473 translate. When the transmission gear 473 is engaged with one of the tooth plates 481, the transmission gear 473 will rotate. At this time, the coil spring 482 contracts to accumulate potential energy. When the transmission gear 473 is disengaged from the tooth plate 481, the coil spring 482 releases the potential energy, which makes the transmission gear 473 rotate in the opposite direction. In this cycle, the transmission gear 473 can realize reciprocating rotation, which makes the worm 472 reciprocate, so that the worm wheel 471 drives the rotating seat 45 to reciprocate, and then the heating element 46 swings back and forth along the width direction of the cultivation bed 3.

[0027] Furthermore, the heating element 46 includes a heating plate 461, the interior of the heating plate 461 is a hollow structure, a plurality of air guide tubes 462 communicating with the interior of the heating plate 461 are fixedly connected to the bottom of the heating plate 461, a heating conduit 463 communicating with the interior of the heating plate 461 is fixedly connected to one end of the heating plate 461, and a corresponding heating supply device is externally connected to the inlet end of the heating conduit 463.

[0028] Working principle: By starting the motor 43 to drive the reciprocating screw rod 41 to rotate, the movable frame 44 can reciprocate and translate along the axial direction of the reciprocating screw rod 41, which makes the heating element 46 translate along the length direction of the cultivation bed 3, and the transmission gear 473 translates following the movable frame 44. When the transmission gear 473 is engaged with one of the tooth plates 481, the transmission gear 473 will rotate. At this time, the coil spring 482 contracts to accumulate potential energy. When the transmission gear 473 is disengaged from the tooth plate 481, the coil spring 482 releases the potential energy, which makes the transmission gear 473 rotate in the opposite direction. In this cycle, the transmission gear 473 can realize reciprocating rotation, which makes the worm 472 reciprocate, so that the worm wheel 471 drives the rotating seat 45 to reciprocate, and then the heating element 46 swings back and forth along the width direction of the cultivation bed 3, so that the heating element 46 can evenly heat the crops on the cultivation bed 3, which is beneficial to the normal growth of the crops.
