A, characteristics and USES
S1116D rolling wheel sand mixer is an effective and low consumption, new structure of sand mixer, as shown in figure 1. The sand mixer adopts the spring pressure device, centralized lubrication, diabase cast stone plate and other new structure and new materials. To ensure the quality of molding sand, improve productivity, increase service life, have played an important role.
This kind of sand mixer strong adaptability, wide application. Mainly used for foundry sand mixing. Machine casting can be used single sand, dry sand, and self-hardening sand, sand and core sand; Also suitable for glass, ceramic, refractory industry such as mixing all kinds of powder granular materials.

Three, the structure of the machine
The whole machine by the transmission system, lubrication system, mixed run institutions, column device, organism, discharging door, add water device and other parts.
1. The drive system
Transmission system including motor, triangle tape (C - 1726), reducer (figure 2), etc. Main motor hanging below the sand mixer chassis, with first-class triangular tape with the reducer. Speed reducer is composed of level of spiral bevel gears and level of cylindrical gear, fixed directly beneath the sand mixer chassis. Frame bottom shall under three magnetic oil plug, used to gather in the lubricating oil iron filings, reduce wear of gears, bearings, prolong service life.
2, lubrication system,
Lubrication oil pump oil lubrication system. By the motor, gear pump, oiler, pressure relays, oil filter and oil pipe. (see figure 3)
Oil pump motor starts, the precipitation in the bottom of the speed reducer of the lubricating oil through a filter by pump pressure, promote small oil cylinder piston motion, will travel switch, the main motor can start; When oil pump failure or tubing oil, lubricating oil pressure is reduced, the piston under the action of spring force recovery in situ, travel switch off contact, main motor power, sand mixing machine stops working, so we can ensure that sand mixer is in good state of lubrication in the work.
3, rolling body
Mixed run institutions include rolling wheel, the spring pressure mechanism, scraper, etc.
A, rolling wheel
With spring and subtract pressure device, does not need to increase by increasing the weight of the rolling wheel rolling pressure, therefore, rolling wheel weight is lighter; As the permanent mold casting, rolling wheel surface has good abrasion resistance. The structure (see figure 4)
