With the increasing demand for high-quality skilled talents in social development, environmental engineering majors in higher vocational colleges must pay attention to the improvement of the teaching quality of engineering drawing courses. Through the reform of traditional environmental engineering drawing teaching, it is combined with CAD teaching. Focusing on the cultivation of students' professional knowledge and practical application skills and computer-aided design capabilities, this will promote the sustainable development of environmental engineering teaching in higher vocational colleges.
Key words: Environmental Engineering; Cartography; CAD; Teaching Reform; Title Paper I. The Necessity of Environmental Engineering Cartography and CAD Teaching Reform Environmental engineering cartography is an important technical foundation course for environmental engineering majors, and is also the basis for the implementation of environmental engineering projects. This course focuses on cultivating students' image thinking ability, spatial imagination ability, aesthetic ability, design expressive ability, and innovative configuration ability. It has the characteristics of strong practicality. Therefore, the environmental engineering drawing curriculum must be constructed in a social demand-oriented way. Technology is the main line, and the teaching model based on practical engineering emphasizes the improvement of students' environmental engineering awareness, quality and practical ability in teaching. The CAD drawing teaching as an important way to cultivate student environmental engineering drawing practice skills, most of the vocational colleges often do not handle the relationship between the two. Some colleges combined environmental engineering drawing and CAD drawing into one course, and focused teaching after CAD teaching was placed in the teaching content of engineering drawing. Due to restrictions on classes, students did not study computer drawing enough, resulting in poor teaching results; some schools The school set environmental engineering drawing and CAD drawing as two independent courses. Although the abundance of the two courses was guaranteed, due to the repetition of many teaching contents and the large number of links, students were When learning two courses, it is impossible to effectively combine drawing knowledge and computer-aided design techniques, which is not conducive to the improvement of students' comprehensive drawing ability. Therefore, the reform of environmental engineering cartography and CAD teaching has highlighted its necessity. Only by integrating the two together can we really solve the problem of the disconnection between engineering drawing and CAD technology. In teaching, teachers should regard environmental engineering drawing as the knowledge base for learning computer graphics, and computer graphics as an important method to improve the effectiveness of environmental engineering drawing learning. At the same time, based on mastering the theory of drawing theory, the use of computer graphics technology is completed. The large assignments enable students to combine theory with practice, improve professional knowledge, practical application and computer-aided design capabilities, and lay a solid foundation for subsequent coursework.
Second, the specific implementation strategy of environmental engineering drawing and CAD teaching reform (a) optimization of the curriculum material selection of teaching materials is one of the key aspects of environmental engineering drawing and CAD teaching reform. In order to ensure that students can fully grasp the basic knowledge and professional knowledge and achieve the teaching objectives of higher vocational education, they should make their own choices or use textbooks according to the requirement of environmental engineering drawing. The content of the teaching materials should highlight the characteristics of non-mechanical drawing, covering the basic principles of drawing, common engineering drawings of the professional, etc., and ensure that the drawing process can be presented using CAD software to enhance the closeness of the combination of environmental engineering drawing and computer graphics. In the compilation of teaching materials, we must strengthen traditional teaching content such as drawing basics, projection concepts, and configuration expressions, appropriately reduce old teaching content such as descriptive geometry, and greatly increase modern advanced knowledge based on computer three-dimensional geometric modeling. The selection of teaching materials should be based on the characteristics of environmental engineering expertise as the starting point, and on the basis of ensuring the improvement of basic theories, building construction drawings, pipe construction drawings, water supply and drainage engineering drawings, etc. should be added to lay a solid foundation for professional courses. By optimizing and adjusting teaching materials, students can always be in the concept of shape in their learning, extending from small three-dimensional, combined bodies, to architectural forms, to buildings, water supply and drainage systems, and pipeline systems, allowing students to construct environmental engineering drawings. The overall outline. In order to integrate the CAD technology into the environmental engineering drawing teaching materials, we should combine the design features of the environmental engineering, using the example teaching method, and pay attention to the cultivation of students' practical ability and the accumulation of practical experience.

This poultry feed pellet making machine has roller-driven design which ensures more powerful compression on the materials, so it can process hardwood materials into biomass pellets more easily than other die-driven pellet mills. With self-lubrication system and a little large capacity 80-700kg/h, it is an ideal choice for you to start a pellets business at home or workshop. High efficiency and low power consumption, our roller-driven pellet mill can make profits quickly for you. Roller Driven Flat Die Pellet Mill Working Principle The main parts of flat die pellet mill are two rotating rollers and a stationary pellet die. When the machine works, the rotating roller will press material into the die hole of the stationary die. There are two highlights of pellet mill driven by rotating rollers. One is that this design can prolong pellet mill service life, the other is it make wood pellets more smooth and solid.
