Description

Technical Field

[0001] The utility model relates to the technical field of trenching machines, in particular to a trenching machine for blueberry planting. Background Art

[0002] A trencher is a commonly used agricultural machinery. For agricultural products that require cultivation, operations such as trenching, ridge formation, film embedding, matrix filling, film covering, and punching are required. The trenching is generally done manually or using a trencher.

[0003] Before planting blueberries, the land where blueberries are planted needs to be furrowed to facilitate planting blueberry seeds in the land. Existing furrowing machines use furrowing knives to dig the land through rolling cutter discs. However, since the furrowing knives are fixedly connected to the cutter disc, the number of furrowing knives cannot be increased or decreased according to actual needs, and the distance between the furrowing knives cannot be adjusted, which affects the planting spacing of the seeds. At the same time, the furrowing knives are prone to wear and tear, and are difficult to repair or replace. Utility Model Content

Its function is to slide the mounting block to the inner side of the connecting port of the connecting knife, so that the mounting block and the trenching knife can be installed on the cutter disc, which is convenient for disassembly of the trenching knife and at the same time, it is also convenient to adjust the spacing between the trenching knives.

[0009] Preferably, the mounting groove is an arc-shaped groove, the mounting groove is opened on the outer surface of the protective plate, the mounting groove is in multiple groups, the bolt one is rotated to connect the screw groove one, and the inner bottom of the mounting groove is also provided with a screw groove one, whose function is to slide the mounting block to the inner side of the knife connection port, so that the mounting block is at the innermost side of the mounting groove, and then by rotating the bolt one, the mounting block can be fixedly connected to the inner side of the mounting groove, thereby fixing the trenching knife to the outer side of the knife disc.

[0010] Preferably, the sealing plate is in the shape of an arc-shaped plate, and the sealing plates are in multiple groups. The sealing plates are fixedly connected to the outer surface of the protective plate by rotating the two bolts and connecting the two screw grooves. Its function is to fix the sealing plate to the outer surface of the cutter disc by rotating the two groups of bolts, thereby closing the installation groove to prevent affecting the trenching operation.

At the same time, it is convenient to repair or replace the trenching knife, thereby facilitating the planting of blueberry seeds.

[0014] 2. Under the cleaning action of the cleaning brush, when there is soil adhering to the trenching knife, as the cutter disc rotates, the trenching knife is driven through the connecting groove, so that the connecting groove can clean up the soil adhering to the trenching knife, preventing the soil from adhering to the trenching knife and affecting the excavation of the land. At the same time, it prevents the soil from being brought to the inside of the protective plate, making it difficult to clean the inside of the protective plate. BRIEF DESCRIPTION OF THE DRAWINGS
