The technical scheme that the utility model technical solution problem adopts is:

A break-in feed material mixer, is comprised of housing, feeding box, discharging opening, mechanical driving device and stirring feed mechanism; It is characterized in that, described feeding box has two, two feeding boxs be arranged in parallel at before housing and and housing be connected as a single entity, two feeding boxs are respectively equipped with the regulating gate for material loading proportioning; Described mechanical transmission mechanism comprises motor, FEEDBACK CONTROL friction coupling device and gear transfer box, and gear transfer box separates two output shafts arranged side by side; Described stirring feed mechanism is by bearing, two parallel main shafts to be set in housing, is respectively the first main shaft and the second main shaft; The front end of two main shafts stretches out housing and by shaft coupling, is connected with two output shafts of gear transfer box respectively after feeding box; Two main shafts are equipped with spiral propeller in feeding box, two main shafts are equipped with helical blade and fore-and-aft plane blade in housing, require the plane of fore-and-aft plane blade on main shaft axial section, the rotation of fore-and-aft plane blade is thrown to opposite one side but non-axial advance by material from a side of mixer; Helical blade on every main shaft and fore-and-aft plane blade alternate are arranged, the helical blade on two main shafts and the interlaced layout of fore-and-aft plane blade; Described discharging opening be arranged on housing rear portion wherein a main shaft below, and this main shaft is that end is that root main shaft of helical blade.

During work, motor starts from zero rotating speed, by each axle of FEEDBACK CONTROL friction coupling device driven gear transfer case, rotates, and realizes the decomposition of speed change and motion, two output shafts of transfer case drive respectively two main shafts to rotate, and two main shafts drive two screw propulsion pay-offs to rotate the ratio charging that realizes material; Helical blade rotation realizes the complex function of material stirring and propelling, and fore-and-aft plane blade rotary is realized the full section agitating function of material; Helical blade and fore-and-aft plane blade are staggered and have realized segmentation break-in propelling and the full section stirring of material, thereby have increased the stirring of material and advanced path, have improved the mixing effect to material.

By above-mentioned operation principle, complete machine structure is simplified, system compact is simple, is convenient to safeguard, energy consumption is lower, and machine volume is little, lightweight, and little, the convenient transportation that takes up room is more suitable for using in the limited construction environment of the inferior working space of coal mine.In addition, the use of FEEDBACK CONTROL friction coupling device has well solved the soft start problem of equipment, has avoided equipment in start-up course, motor and electrical network to be impacted.By material loading proportioning regulating gate to regulate the mixed proportion of material, with the simplest winding machine material loading and accurate dosing.
