Magnetic separation electromagnet 44（Or permanent magnet）, oil filter 39, flange arrangement 45, spiral buckle and eye-splice etc. be routine Technology, concrete structure are no longer described in detail.

The pressing screw 10 includes some pressing screw sections in a tubular form, is snapped connection together between adjacent pressing screw section；It is described to wear Screw rod 11 is through all pressing screw section threaded connections of all pressing screw Duan Bingyu.

The front end of pressing screw 10 is connected by buckle structure with main shaft 22 to transmit bigger moment of torsion, and buckle structure can be optional Any of following two structures：1. as shown in Figure 10, buckle structure include be arranged on the front end of pressing screw 10 spiral buckle and The spiral buckle of the rear end of main shaft 22 is arranged on, the spiral buckle of the rear end of main shaft 22 is mutually suitable with the spiral buckle of the front end of pressing screw 10 Match somebody with somebody.

2. as shown in figure 11, the front end of pressing screw 10 is connected by buckle structure with main shaft 22 to transmit bigger moment of torsion, card Buckle structure includes the eye-splice for being arranged on the front end of pressing screw 10 and the eye-splice for being arranged on the rear end of main shaft 22, the eye-splice and squeezing of the rear end of main shaft 22 The eye-splice of the front end of spiral shell 10 is mutually adapted.

Pulley cover 47 is covered with the big belt pulley 6 and small belt pulley 7 and driving belt, to protect belt drive Structure.The bearing 30 is thrust bearing 30 or pressure bearing 30.Larger axial force during adapting to work.

Wherein, the water cavity 35 of cooling heat transferring case 24 can be connected on the water supply of factory by its water inlet 40 and delivery port 41 On pipeline（External water inlet pipe now described previously and external outlet pipe are the water supply line of factory）, naturally it is also possible to make into water Mouth 40 is connected on the water supply line of factory（Water supply line is as external water inlet pipe）, and delivery port 41 is connected external draining Pipeline（Drainage pipeline is as external outlet pipe）.Thermometer 16 is used for monitoring the work temperature lubricated in good grain bulking machine Degree.The front end external diameter of expansion control first 20 is less than the front inner diameter of discharging opening 18, and the rear end external diameter of expansion control first 20 is more than The front inner diameter of material mouth 18 and the back end inside diameter for being less than discharging opening 18；So, expansion control first 20 can be stretched into tubaeform to go out Material mouth 18.The front and back position of discharging opening 18 is stretched into regulation expansion control first 20, can be with the width of tapping channel 21.Referring to accompanying drawing 5, Expansion control first 20 position it is more forward, tapping channel 21 is narrower, expansion control first 20 position more rearward, tapping channel 21 It is wider.Therefore, by controlling the front and back position of expansion control first 20, the thickness degree after being handled with control material.

In use, start motor 9, by material（Such as corn and soybean grain）Put into by charging aperture, material enters along V-shaped Expects pipe 4 falls into press chamber 3 after turning back, passing through electromagnet 44（It is powered during work）When, the iron class impurity in material is by electromagnetism Iron 44 is adsorbed onto on the tube wall of feed pipe 4, prevents iron class impurity from falling into press chamber 3 so as to influence crudy.After motor 9 starts, Pressing screw 10 is driven to rotate by belt transmission, pressing screw 10 drives spiral pushing blade 12 thereon to rotate integrally.

After material falls into press chamber 3, spiral pushing blade 12 promotes material to move from the front to the back in rotation.Because spiral pushes away The pitch of blade 12 is sent to be gradually reduced from the front to the back, therefore the amount that material is compressed during spiral pushing material in rotation gradually increases Greatly, pressure gradually rises, and is advantageous to being smoothed out for puffing process.Material is in moving process, when by stirring gear stick 13 It is stirred gear stick 13 to be stopped, so as to be stirred, material is distributed more uniform, lifts processing quality.

Connecting screw 23 connects pressing screw 10 and main shaft 22 in the axial direction, and buckle structure diametrically connects pressing screw 10 and main shaft 22 so that be suitable to transmit high torque between pressing screw 10 and main shaft 22, be also less likely to be damaged after long-term work.This attachment structure Also it is highly convenient for connecting and dismantling.

After motor 9 starts, start scavenge oil pump 37, the oil in oil pocket 34 passes through oil filter 39, oil inlet pipe 38, the and of scavenge oil pump 37 Enter bearing chamber after oil return pipe 36.When the oil level in bearing chamber higher than overflow oil pipe 33 when, lubricating oil through spilling oil pipe again to Lower inflow oil pocket 34, and when flowing through profit dividing plate 26, heat exchange occurs with the water in water cavity 35 and is cooled.After cooling Lubricating oil is pumped back to bearing chamber by oil return again, so as to prevent the high oil temperature of lubricating oil in bearing chamber from bringing harm.

The setting of thermometer 16 and pressure gauge 17, it is easy to the temperature and pressure before material is expanded in monitoring work, so as to more Accurately adjustment work process, improve expansion effect.When material pushes to discharging opening 18 by spiral pushing blade 12, control is inflated System first 20 is stopped, discharging boot 8 can only be entered by tapping channel 21.When material enters discharging boot 8, pressure drops rapidly It is low, material（Grain grain）It is interior in the moisture instant vaporization of superheat state so as to which violent explosion occur, obtain material expanded.

Above example is only to illustrative and not limiting the technical solution of the utility model, although with reference to above-described embodiment pair The utility model is described in detail, it will be understood by those within the art that：The utility model can still be entered Row modification or equivalent substitution, without departing from any modification or partial replacement of spirit and scope of the present utility model, it all should Cover among right of the present utility model.
