[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] Reference Figure 1-4 The utility model provides an embodiment: a teaching device for environmental landscape design, including a base 8, a screw sleeve 9 is fixedly connected to the middle of the upper part of the base 8, a screw 10 is connected to the inner thread of the screw sleeve 9, telescopic rods 6 are fixedly connected to the upper ends of the base 8, a U-shaped frame 3 is fixedly connected to the upper end of the telescopic rod 6, and the bottom of the U-shaped frame 3 is rotatably connected to the screw 10, and the U-shaped frame 3 can be supported and limited by the telescopic rods 6 at both ends;

[0026] A second bevel gear 11 is fixedly connected to the screw 10, a first drive motor 4 is fixedly connected to one end of the inner side of the U-shaped frame 3, a first bevel gear 5 is fixedly connected to the output end of the first drive motor 4, the first bevel gear 5 and the second bevel gear 11 are meshed with each other, a connecting block 2 is fixedly connected to the inner side of the U-shaped frame 3, and a teaching screen 1 is fixedly connected to the inner end of the connecting block 2. Starting the first drive motor 4 can rotate the first bevel gear 5, which can drive the second bevel gear 11 and the screw 10 to rotate under the action of meshing, and at the same time, the lifting operation of the teaching screen 1 can be realized under the action of the threaded connection, thereby improving the practicality of the entire teaching screen 1 and improving the teaching quality of the entire environmental landscape design;

[0027] A speaker 12 is provided inside the connection block 2, and the speaker 12 at both ends can increase the volume during teaching;

[0028] The upper and lower ends of the teaching screen 1 are fixedly connected with a connecting frame 16, and a second drive motor 15 is arranged on one side of the connecting frame 16. A lead screw 17 is arranged inwardly through the output end of the second drive motor 15. The lead screw 17 can be rotated by starting the second drive motor 15. A threaded block 14 is threadedly connected to the lead screw 17. A slot 18 is arranged at one end of the connecting frame 16. A cleaning brush 13 is arranged upward through the slot 18 of the threaded block 14. Under the action of the threaded connection, the threaded block 14 can drive the cleaning brush 13 to reciprocate, thereby performing a self-cleaning effect on the dust on the teaching screen 1, which not only reduces the teaching intensity of the teaching staff, but also increases the clarity of the teaching screen 1.

[0029] Universal wheels 7 are provided at the four lower ends of the base 8, a jack 20 is provided inside the base 8, and an extended end of the jack 20 is fixedly connected to a support plate 19.
