This section replaces GB/T 7920.10-2006 "Terms and Commercial Specifications for Road Construction and Maintenance Equipment Stabilizing Soil Mixers".

Compared with GB/T 7920.10-2006, the main changes in this section are as follows.

--- Increased the scope of application "not applicable to agricultural stable soil mixers" (see Chapter 1);

--- Deleted the "ISO 13539 earthmoving machinery trencher terminology and commercial specifications" in the normative references (see the.2006 edition

chapter 2);

--- In terms and definitions, "adjustable mixer shell" was changed to "adjustable mixing chamber", and "fixed mixer shell" was changed to "fixed

Mixing chambers "(see 3.4 and 3.5, 3.4 and 3.5 of the.2006 edition);

--- In the type, "mixed type" was changed to "mixed type", and "ploughing type" was deleted (see 4.1, 4.1 of the.2006 version);

--- Deleted the "working device adopts the form of ploughing device" in the type and arrangement of working devices (see 4.2,.2006 version

4.2);

--- The driving principle of the working device was changed to "the movement of the mixing device is realized by a mechanical or hydraulic drive system" (see 4.3,.2006

Annual version 4.3);

--- Added "General Information", incorporated "Transportation Dimensions" into "General Information", and increased "Transport Quality" (see 5.2,.2006 edition

5.2);

--- "Gap" changed to "Ground clearance" (see 5.3.2, 5.2.3 of the.2006 edition);

--- "Turning diameter and turning radius" was changed to "turning radius", and the "inside turning radius of the working device and the

Outer turning radius "(see 5.3.4, 5.2.5 of the.2006 edition);

--- In the column item in "Characteristic Angle", the "lateral tilt angle/lateral angle of the rotor working room" has been added (see 5.3.6);

--- Increased steering characteristics of the articulated chassis (see 5.9);

--- Removed "Sleeve coupling blade cutter" (see 5.9.1.1 of.2006 edition);

--- Removed the "casing connection sheet" (see 5.9.1.2 of the.2006 version);

--- Deleted the "Ploughing Device" (see 5.9.2.5 of the.2006 version);

--- Add "a" to the "flow adjustment method" column to automatically adjust the flow using this machine's working speed servo control system (this mode

Whether it applies to the forward and backward movement of the machine, or the situation of forward or backward movement) ";

Is "automatic on/off control by machine working speed" (see 5.11.1.3,.2006 version 5.10.1.3);

--- Change the "load control system for knives" to "load control system for mixing devices (knives)";

Gradually reduce "to" stepless deceleration of travel speed ";" to adjust rotor speed by automatic control "

"Automatic speed control and adjustment"; added "hydraulic overload detection and protection device" (see 5.11.4,.2006 version 5.10.4).

This section uses the translation method equivalent to ISO 15688..2012 "Road Construction and Maintenance Equipment Stabilizing Soil Mixer Terminology and Commercial

specification".

The Chinese documents that have a consistent correspondence with the international documents referenced normatively in this section are as follows.

3 terms and definitions

The following terms and definitions apply to this document.

3.1

Soil stabilizer

A self-propelled, towed, or truck-mounted machine that has the ability to crush, disperse, mix, and loosen road paving materials, and combine them with a

Or multiple stabilizers (such as fillers, cement or lime).

Note. The stabilized soil mixing machine improves its mechanical properties and physical properties by mixing the stabilized soil material with a binder (such as filler, cement, lime, etc.) or filler.

performance.

3.2

Tractor tractor

A vehicle that carries all the components and tow the mixing device when working and when transferring between construction sites.

3.3

Mixing device

A device consisting of moving parts that perform in-situ processing (such as stirring or dispersing) of stabilized earth material.

Note. The mixing device usually consists of a power-driven rotor equipped with a cutter, which rotates during the mixing operation (see Appendix A, Figure A.1 ~

(Figure A.5). Another type of mixing device uses special cutters to reciprocate during mixing operations (see Figure A.6).

3.4

Variablemixerchamber

The mixing chamber equipped with gates or pleats can control the mixing time of materials in the mixing chamber.
