ICS65.040.20 Machinery Industry Standard of the People's Republic of China JB/T7881.1~7881.5-1999www.bzxz.net Sheep shearer Published on August 6, 1999 National Bureau of Machinery Industry Implemented on January 1, 2000 JB/T7881.2-1999 This standard is a revision of JB/T7881.2-95 "Sheep shearer models and basic parameters". Compared with JB/T7881.2-95, the main technical content of this standard has changed as follows: in the model representation method, 95M口76.2 is changed to 9MJ口76.2 (口-characteristic code, different models have different codes). This standard replaces JB/T7881.2-95 from the date of implementation. This standard is proposed and managed by Hohhot Animal Husbandry Machinery Research Institute. The drafting unit of this standard: Hohhot Animal Husbandry Machinery Research Institute. The main drafters of this standard: Hai Yurong, Guo Xiuyun. Scope Machinery Industry Standards of the People's Republic of China Types and basic parameters Sheep shearer Sheep shearer--Typesandbasicparameters This standard specifies the types, models and basic parameters of sheep shearers. This standard is applicable to flexible shaft type or articulated shaft type and direct-acting sheep shearers. Type 2.1 According to the power transmission method: a) flexible shaft type or articulated shaft type; b) direct-acting type. 2.2 According to the shearing width: a) wide width; b) narrow width. Basic parameters The basic parameters of the wool shearing machine shall comply with the provisions of Table 1. Table 1 Blade swing frequency Cutting width Grip diameter Rated power Without sheath Flexible shaft type Note: The parameters in the table are not applicable to pneumatic and hydraulic wool shearing machines in direct-acting type. Model Model indication method Direct acting JB/T7881.2-1999 Replace JB/T7881.2—95 Flexible shaft Moving 4.2 Model example Example 1: 9MJR-76.2 76.2(60.3) JB/T7881.21999 Shear Cutting width, mm Feature code: R——flexible shaft type Z——direct-acting type P——medium frequency type C-series type L—DC type Q——pneumatic type Y——hydraulic type Sheep shearing machine category code Animal husbandry machinery product code Flexible shaft (or articulated shaft) type sheep shearing machine, cutting width 76.2mm. Example 2: 9MJZP-60.3 Medium frequency type sheep shearing machine, cutting width 60.3mm. Tip: This standard content only shows part of the intercepted content of the complete standard.
