Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a soil loosening machine for agricultural planting and seedling raising. Background Technique

[0002] Agricultural planting is one of the main components of agriculture. Agricultural planting utilizes the life functions of plants and is a social production department that obtains food, non-staple foods, feeds, and industrial raw materials through artificial cultivation. The agricultural planting soil loosening machine is a machine that facilitates tilling the land during agricultural planting. Compared with traditional soil loosening tools, it has the advantages of simplified construction technology, reduced construction machinery, high productivity, and good production safety. The soil loosening machine is more and more widely used in agricultural planting.

[0003] However, some existing soil loosening machines for agricultural planting and seedling raising do not have the function of weeding during the soil loosening process. A large number of weeds are easily wound around the outside of the soil loosening roller, causing the soil loosening roller to be unable to rotate for soil loosening operations. At the same time, the tilled land often leaves soil clods, and it takes a long time to deal with the soil clods. Common soil loosening machines are difficult to clean hard soil clods. For this reason, we propose a soil loosening machine for agricultural planting and seedling raising to solve the above problems. Content of the Utility Model

[0028] When the utility model works: It is installed on the front side of the trolley through the mounting holes on the U-shaped block 29. During use, the second electric telescopic rod 18 is started to drive the first horizontal plate 6 and the second horizontal plate 7 to move downward to a suitable position. The second motor 11 is started to drive one of the crushing rollers 8 on the left side to rotate. The crushing roller 8 drives the corresponding transmission roller 9 to rotate. The transmission roller 9 on the left side drives the transmission roller 9 on the right side to rotate through the belt 10. The transmission roller 9 on the right side rotates to drive the crushing roller 8 on the right side to rotate. The crushing roller 8 rotates to cut the weeds. The grass suction machine 13 is started to collect the weeds through the diversion cover 30 and discharge them into the collection box 16 through the U-shaped pipe 15.
