[0004] The technical problem to be solved by the present invention is to provide a pruning machine blade assembly which can perform arc pruning in the width direction and perform specific angle pruning on the edges and corners of long strips.

[0005] The technical solution of the present invention is to provide a pruning machine blade group with the following structure, including a first blade, a second blade, a pressure strip and a bottom plate, an eccentric wheel assembly and a gear, the eccentric wheel assembly is connected to the gear, the tail end of the first blade and the tail end of the second blade are connected to the eccentric wheel assembly, one side of the first blade is provided with a plurality of evenly arranged first blade heads, and the other side is provided with a plurality of evenly arranged second blade heads, one side of the first blade is provided with a plurality of evenly arranged third blade heads, and the other side is provided with a plurality of evenly arranged second blade heads, all the first blade heads and all the third blade heads are located on one side, all the second blade heads and the second blade heads are located on the other side, and the first blade and the second blade slide back and forth along the length direction; it is characterized in that: all the first blade heads and the blade body form a structure tangent to the arc, the structure is arranged along the width direction of the blade, the third blade head of the second blade corresponds to the first blade one by one and the two work in parallel.

[0006] In the pruning state, the first blade head and the second blade head are simultaneously tangent to the pruned spherical surface.

[0007] All the first blade heads and the third blade heads are bent toward the pressure strip, thereby forming an angle α with the blade body.

[0008] The angle α is 90 to 160 degrees.

[0009] After adopting the above structure, the present invention has the following advantages: 1. Since all the first blade heads of the first blade form a structure tangent to the arc with the blade body, the structure is arranged along the width direction of the blade, so that the arc surface can be trimmed in the width direction. For the arc spherical surface, a spherical surface can be trimmed in multiple sections through the tangent mechanism, so that the shape and position of the pruned shrubs can be arranged and measured, so as to achieve the required shape more quickly. 2. The edges and corners of the long strip are trimmed at a specific angle. For example, if there is a specific angle between the side and the top surface, the tangent structure can be used to directly trim the side and top surfaces together in a straight line, without having to trim the side and top surfaces separately for multiple times.
