Design differences of the trail harrow
Distinctive features of the trailing harrow (heavy) 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 cross-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, avoids the dangerous transitional section of the tooth in the area of the square thread.
The links that collect the load-bearing beams into a train are made of strong 30G2R corrugated sheet steel, used for
manufacturing discs drill bits and lugs. 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 provide the necessary angle of installation of the teeth (23° or 45° from the vertical).
The scheme of the arrangement of the teeth with an interaxial distance of adjacent teeth in the plane of 25 mm. and the diagonals of the square are 22 mm. provides almost complete coverage of the working area across the entire width of the gripper when constructing a loop consisting of ten load-bearing beams with teeth.
The supporting frame allows you to install additional tanks and systems for applying the necessary chemicals and fertilizers.
