Product Models and Main Parameters of Disc Harrows
JB/T6279.1-1992
Product Models of Disc Harrows are composed of Category Code, Feature Code, Main Parameters and Modification Code according to NJ89. 1B
Modification Code
Basic Main Parameters/Modified Main Parameters
Feature Code
Category Code
3.1 Category Code is composed of Classification Code and Group Code. The product category code of Disc Harrows is 1B. 1 Classification Code, indicating tillage and land preparation machinery. B Group Code, is the first letter of the Chinese Pinyin of "harrow" in the basic name of Disc Harrows. 3.2 The characteristic code is represented by the Chinese phonetic letters of the main characteristics of the disc harrow product. The first letter is the type code;
Q is light; J is medium; Z is heavy. bzxZ.net
The second letter represents the code for the connection type of the disc harrow and the tractor: X is suspended; B is half suspended; the traction type is not represented by letters. The third letter represents the code for the harrow group configuration. D is a one-mounted type; the offset type is not represented by letters. 3.3 The main parameter refers to the working width of the disc harrow, in meters, with one decimal place. The main parameters are divided into basic main parameters and modified main parameters, separated by "". If there is no modification, "". 3.4 The modification code is indicated by adding "A" after the basic type. If there are several modifications, the sequence number is added in sequence starting from 2 after the letter A. 3.5 Marking example
Basic type working width is 1.5m (16 pieces), modified working width is 1.7m (one set of additional target pieces is added to each of the front and rear rows, becoming 18 pieces) suspended offset two-row two-group light disc harrow: 1BQX-1.5/1.716/18 pieces suspended offset light disc harrow. Approved by the Ministry of Machinery and Electronics Industry on June 10, 1992 and implemented on July 1, 1993
