Design features of the trailing tooth harrow BZSh-21.
Distinctive features of the trailing (heavy) BZSh -21 tooth harrow are the following structural and technological solutions, which allow to significantly increase reliability and working life, as well as improve maintainability.
• The tooth is made of a square of 65G steel with appropriate heat treatment. The use of a square milled on two sides into a sharp wedge ensures the work of the cutting edge of the square and the wedge working surface with the effect of self-sharpening. A sharp wedge easily penetrates the soil.
• When using the teeth of a thick-walled pipe with a square section as a supporting beam, it became possible to orient a square hole with a section of 16x16 in one wall of the pipe, which in turn allows you to avoid the dangerous transitional section of the tooth in the area of the square thread.
• The links that assemble the load-bearing beams into a train are made of strong 30G2R steel, used formanufacturing discs drill bits, laps. Also, the frame structure of the link gives the train stability when working without demolishing the trail. Fastening the link to the toothed beam with the help of three-dimensional axes significantly increases the maintainability of the site.
• Stops stamped from sheet steel, installed on the tooth beam ensure the necessary angle of installation of the teeth (23° or 45° from the vertical).
• The arrangement of the teeth with an interaxial distance of adjacent teeth in the plan of 25 mm and a diagonal of the square of 22 mm provides almost complete overlap of the working area over the entire width of the grip in the construction of the loop, which consists of ten supporting beams with teeth.
• The supporting frame allows you to install additional tanks and systems for applying the necessary chemicals and fertilizers.
