Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 The utility model provides a technical solution: a heat-resistant cultivation device for rice in the heading period, comprising a supporting base frame 1 and a warming shell 9 detachably mounted on the supporting base frame 1, a culture tank 3 is arranged in the inner cavity of the warming shell 9, the inner cavity of the warming shell 9 is limitedly connected with the culture tank 3 by cooperating with a stepped groove 10, a warming chamber 13 is arranged in the lower part of the inner cavity of the warming shell 9, a hot air inlet pipe 14 and a hot air outlet pipe 15 are respectively connected on both sides of the warming chamber 13, and an electromagnetic valve 16 is arranged on the hot air inlet pipe 14 and the hot air outlet pipe 15; a temperature sensor is inserted through the lower part of the culture tank 3, the temperature sensor penetrates the warming shell 9, and a through groove 12 matching the temperature sensor is provided on the warming shell 9.

[0024] In the utility model, the inner cavity of the warming shell 9 is limitedly engaged with the culture tank 3 by cooperating with the step groove 10. At the same time, since the warming shell 9 is provided with a through groove 12 matching the temperature sensor, personnel can quickly and easily disassemble the culture tank 3; high-temperature hot air is introduced into the warming chamber 13 through the hot air inlet pipe 14, and then the hot air inlet pipe 14 and the solenoid valve 16 in the hot air outlet pipe 15 are closed, so that the hot air stays in the warming chamber 13 for a long time, thereby enabling the roots of the rice to maintain a high temperature state during the ear stage, so as to monitor the heat resistance of the rice during the ear stage.

[0025] Reference Figure 3 As shown, in this embodiment, a hanging plate 2 is arranged on the end surface of the heating shell 9, a notch for the hanging plate 2 to be inserted and matched is arranged on the supporting base frame 1, and a snap-in edge 4 matching the step groove 10 is arranged on the upper part of the culture tank 3. The setting of the hanging plate 2 and the snap-in edge 4 can facilitate the rapid installation and removal of the culture tank 3 and the heating shell 9 in daily life.

[0026] Reference Figure 2 As shown, in this embodiment, the upper part of the culture tank 3 is symmetrically provided with a lifting frame 5, and the two sides of the heating shell 9 are provided with elastic pressing frames 11 capable of pressing the lifting frame 5. After the culture tank 3 and the heating shell 9 are limitedly engaged, the elastic pressing frame 11 can be deformed to press against the lifting frame 5, so that the culture tank 3 is stably installed in the heating shell 9; at the same time, when the culture tank 3 is disassembled, after the elastic pressing frame 11 is released, the culture tank 3 can be conveniently lifted out.

[0027] Reference Figure 3 and 4As shown, in this embodiment, a sealing sleeve 6 is fixedly provided on the cavity wall of the culture tank 3, and the temperature sensor is inserted into the inner cavity of the culture tank 3 through the sealing sleeve 6. The provided sealing sleeve 6 can effectively ensure the sealing performance of the inner cavity of the culture tank 3 after the temperature sensor is inserted and installed in the lower part of the inner cavity of the culture tank 3, thereby preventing heat from leaking out from here.

[0028] Reference Figure 2 As shown, in this embodiment, a sealing gasket 8 is arranged between the matching stepped groove 10 located at the lower part of the inner cavity of the heating shell 9 and the lower end surface of the culture tank 3. Since the culture tank 3 and the soil therein have a certain weight, the sealing gasket 8 is compressed, thereby effectively ensuring the sealing performance between the bottom of the culture tank 3 and the heating chamber 13, and effectively preventing the hot air in the heating chamber 13 from escaping through the gap. When the elastic pressing frame 11 squeezes the lifting frame 5, the culture tank 3 can stably squeeze and compress the sealing gasket 8, thereby ensuring the sealing performance of the culture tank 3 and the heating chamber 13 when the entire cultivation device is moved.

[0029] Reference Figure 4 As shown, in this embodiment, the lower end surface of the culture tank 3 is evenly and continuously arranged with a plurality of arc-shaped grooves 7, and the arc-shaped grooves are equal in length to the culture tank 3. Since the lower end surface of the culture tank 3 is arranged with the arc-shaped grooves 7 of equal length, the contact area between the bottom surface of the culture tank 3 and the hot air in the heating chamber 13 can be effectively increased, thereby improving the heating efficiency of the culture tank 3.
