In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0017] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0018] In the description of the embodiments of the present invention, "multiple" means at least 2.

[0019] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] Example:

[0021] A tillage machine pressing wheel comprises a main support beam 10;

[0022] The front end of the main support beam 10 is provided with a bayonet 20 and a connecting assembly connected to the beam of the no-tillage machine. The bayonet 20 is a C-shaped structure, which is convenient for quick connection and disassembly with the beam of the no-tillage machine. The connecting assembly includes a sealing plate 21, a connecting bolt 22, and a connecting sleeve 23 symmetrically arranged at the upper and lower ends of the bayonet 20. The upper and lower parts of the sealing plate 21 are penetrated with through holes. The connecting bolt 22 is connected to the connecting sleeve 23 through the through hole so that the bayonet 20 and the sealing plate 21 form a closed structure. This design makes the connecting assembly compact and the connection is firm and reliable.

[0023] The rear end of the main support beam 10 is hingedly connected with a connecting piece 30 of an L-shaped structure. The top end of the long axis of the connecting piece 30 is hingedly connected to the upper end of a pressure spring 40. The lower end of the pressure spring 40 is located in the installation groove 11 at the upper end of the main support beam 10. Four spring pressure adjustment holes 12 are arranged at intervals and through the outer wall of the installation groove 11. According to the soil moisture, a suitable hole position can be selected to be hingedly connected with the lower end of the pressure spring 40. The hole position from front to back represents a greater spring force, that is, the downward pressure of the pressure wheel increases accordingly. The greater the downward pressure, the higher the soil firmness.

[0024] A connecting column 50 is fixedly connected to the short axis of the connecting member 30, and a swing shaft 60 is rotatably connected to the connecting column 50. The two ends of the swing shaft 60 are respectively connected to a pressing wheel bracket 70 and a pressing wheel 71 rotatably arranged between the bottoms of the pressing wheel bracket 70.

[0025] In the above technical scheme, the front end of the main support beam 10 is connected to the beam of the no-till machine through the bayonet 20 and the connecting assembly, which ensures the stable connection between the pressing wheel and the no-till machine. The rear end of the main support beam 10 is hingedly connected to a connecting member 30 with an L-shaped structure, so that the connecting member 30 can rotate around the hinge point (the maximum rotation angle is ninety degrees), thereby realizing the up and down movement of the pressing wheel 71; a connecting column 50 is fixedly connected to the short axis of the connecting member 30, and the pressing wheel 71 can rotate around the swing axis through the swing axis 60 rotatably connected thereto, thereby realizing the left and right movement of the pressing wheel 71, thereby further improving the flexibility and adaptability of the pressing wheel.

[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
