Design features of the tooth trailing harrow BZSh-7

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 operation 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 make a square opening with a 16x16 cross-section in one wall of the pipe, which in turn allows you to avoid a 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 formanufacturing discs drill bits and lugs. Also, the frame structure of the link gives the train stability when working without demolishing the track. Fastening the link to the toothed beam with the help of three-dimensional axes significantly increases the maintainability of the site.(//tractor-service.com)
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 scheme of the arrangement of the teeth with an interaxial distance of adjacent teeth in the plane of 25 mm. diagonals of the square are 22 mm. ensures 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 containers and systems for applying the necessary chemicals and fertilizers.
