[0002] At present, there is a disclosed blade assembly of a pruning machine, which includes a fixed plate, an upper blade, a lower blade, a plurality of bolts, a guard plate and an eccentric wheel assembly; the upper blade and the lower blade are both provided with a plurality of long holes, the upper blade and the lower blade are both provided with a row of cutter heads, the guard plate is arranged on the bottom surface of the tail of the lower blade, and the eccentric wheel assembly includes an eccentric wheel, a driving pin connected to the output end of the motor, and a partition; the partition is located between the tail of the upper blade and the lower blade, the eccentric wheel is located in the tail driving hole of the upper blade and the lower blade, the partition is fixed to the eccentric wheel, and the upper blade and the lower blade reciprocate linearly by the rotation of the eccentric wheel; in addition to two first mounting holes for mounting the driving pin and two second mounting holes for fixed connection with the partition, the eccentric wheel is also provided with a weight reduction structure. The weight reduction structure is three third mounting holes arranged on the eccentric wheel. The three third mounting holes are located in the same semicircle of the eccentric wheel. The third mounting hole is fan-shaped. The driving pin protrudes from the top surface of the eccentric wheel. The guard plate is rectangular, and the inner parts of the four corners are provided with bolt holes for fixing, wherein the two inner holes are circular holes and the two outer holes are waist-shaped holes.

[0003] A partition is added to the tail of the blade group of the above structure. Although the partition is located between the tail of the upper blade and the tail of the lower blade, the partition is not used to separate the tail of the upper blade and the tail of the lower blade to maintain the distance, but is used to drive the tail of the upper blade and the tail of the lower blade, resulting in that the distance between the tail of the upper blade and the tail of the lower blade cannot be accurately maintained. Long-term use will cause the tail of the upper blade and the tail of the lower blade to be uneven, thereby increasing friction. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pruning machine blade group which adds a support plate to the tail of the upper blade and the tail of the lower blade, so that a fixed distance is maintained between the support plate and the bottom plate to form a channel for the tail of the first blade to slide, thereby ensuring the sliding space of the tail of the upper blade and the tail of the lower blade and reducing the friction of the blades.

[0005] The technical solution of the utility model is to provide a pruning machine blade group with the following structure, including a first blade, a second blade, a pressure strip and multiple sets of fixing bolt and nut combinations; the first blade includes a first cutting section at the front end and a first driving ring at the rear end, the second blade includes a second cutting section at the front end and a second driving ring at the rear end, the first blade and the second blade are overlapped up and down and move in a straight line along the pressure strip, the first driving ring and the second driving ring are connected to the driving gear of the pruning machine, and each set of fixing bolt and nut combinations passes through the corresponding long holes above and below the first cutting section and the second cutting section respectively and connects the first blade and the second blade; it is characterized in that: the first driving ring and the second driving ring are arranged on the bottom plate, one end of the bottom plate extends to the first cutting section and the second cutting section, and at least two sets of fixing bolts and nuts pass through the bottom plate to determine the straightness of the bottom plate and the blade; a support plate is provided between the first driving ring and the second driving ring, and the support plate is connected to the bottom plate.
