The utility model has advantages of simple structure, reliable operation and easy maintenance.

Description

The compact type vacuum mud extruder

Technical field:

The utility model relates to the former in the brick and tile production.

Background technology:

De-airing extruder is made up of three parts: the higher level stirs, subordinate extrudes and vacuumized part.Usually vacuumized part is made up of outsourcing vavuum pump and pipeline as appendage.De-airing extruder in the practical application has two types basically, a kind of is that higher level mixing part and subordinate's extruding part overlap transmission system drives by two motors and two respectively, this system is a motor, and---belt pulley---clutch---decelerator is called combined de-airing extruder; The higher level mixing part of another kind of de-airing extruder and subordinate's extruding part all are by a motor and a cover transmission system drives, are called the compact type vacuum mud extruder.

The course of work of compact type vacuum mud extruder is: raw material enters after the stirring of higher level mixing part, is transported in the vacuum chamber by the sealing reamer, and the soil compressing plate that is stirred part is pressed into the extrusion modling adobe in the reamer of extruding of subordinate's extruding part.The power of compact type vacuum mud extruder by decelerator (may be a standard decelerator or standard decelerator add one speed reducer dedicated, or big special-purpose decelerator) slow-speed shaft output, a shaft coupling is installed in end at this slow-speed shaft, in order to drive subordinate's extruding part work, the mangler shaft that just drives mud extruder rotates, on this axle, or therewith the axle direct connection mangler shaft on, a driving gear also is installed simultaneously, drive the higher level mixing part by a cover travelling gear again and carry out work, just drive two shaft runnings.

There is following problem in above-mentioned existing structure:

Driving gear on the slow-speed shaft and the travelling gear that rotates in order to driving higher level shaft, its structure is comparatively complicated, specifically comprise: the driving gear on the slow-speed shaft, middle the follower gear travelling gear of geared end (or to), add that on the shaft two are to gear, amount to 4 gears, cause that the complex structure volume is big, cost is high, maintenance is difficult.

No matter be one big speed reducer dedicated, or standard decelerator add one little speed reducer dedicated, or standard decelerator adds the transmission system of the compact type vacuum mud extruder that the outside travelling gear of installing forms, and has all that centre follower gear (carrier gear) intensity is lower, the problem of easy damage.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, provides that a kind of structure is more compact, simple in structure, cost is low, compact de-airing extruder for ease of maintenaince.

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

The utility model comprises higher level's rabbling mechanism, subordinate's extrusion mechanism and vacuum tank.

Design feature of the present utility model is in described higher level's rabbling mechanism, adopt direct transmission between slow-speed shaft and the stirring main shaft, be included on the described slow-speed shaft and connect firmly driving gear, on described stirring main shaft, connect firmly main shaft to gear, driving gear and main shaft are to directly engagement between the gear, between a pair of shaft, gear and countershaft are meshing with each other to gear with main shaft.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model is reduced to 3 gears by slow-speed shaft to the transmission system of higher level's shaft by 4 travelling gears with original, makes drive mechanism more simple, reliable, and is convenient to maintenance.

2, the utility model is because of having cancelled the lower follower gear of intensity, and all the other strengths of gear teeth are improved respectively, thereby have strengthened functional reliability.

Number in the figure: 1 higher level's rabbling mechanism, 2 subordinate's extrusion mechanisms, 3 vacuum tanks, 4 soil compressing plates, 5 blades, 6 reamers, 7 slow-speed shafts, 8 stir main shafts, 9 driving gears, 10 main shafts to gear, 11 countershafts to gear, 12 free gear hubs, 13 wear-resisting empiecements

The specific embodiment:

Referring to Fig. 1, include higher level's rabbling mechanism 1, subordinate's extrusion mechanism 2 and vacuum tank 3 in the present embodiment.Wherein, higher level's rabbling mechanism 1 is to gear-driven a pair of shaft, and the front end of shaft is a pair of pressure mud axle that is positioned at vacuum tank 3, and it radially is fixedly connected with soil compressing plate 4 to press mud axle upper edge; Subordinate's extrusion mechanism 2 is for having the reamer 6 of spiral blade 5.

Referring to Fig. 2, in the present embodiment, in higher level's rabbling mechanism 1, adopt direct transmission between slow-speed shaft 7 and the stirring main shaft 8, be included in and connect firmly driving gear 9 on the slow-speed shaft 7, connect firmly main shaft to gear 10 on stirring main shaft 8, driving gear 9 and main shaft are to directly engagement between the gear 10, between a pair of shaft, gear 10 and countershaft are meshing with each other to gear 11 with main shaft.

Referring to Fig. 3, Fig. 4, in the present embodiment, in vacuum tank 3, adopt " double-vane " structure at soil compressing plate 4, promptly, two soil compressing plates 4 are set with axial symmetry pressing on the mud axle, form double-vane.This structure is more effective than existing " single-blade " version.

Referring to Fig. 5, Fig. 6, in the present embodiment, in subordinate's extrusion mechanism 2, adopt floating structure at reamer 6, this floating structure is at the front end that is positioned at reamer 6, is one section free gear hub 12 (shown in Figure 6).The existence of this free gear hub 12 can be adjusted the length of reamer 6 according to different material needs when equipment assembles, specifically be to realize by blocking arbitrarily in its free gear hub 12 positions.The suitable length of reamer 6 can improve work efficiency effectively.

Referring to Fig. 7, in order to improve the anti-wear performance of spiral blade 5 on the reamer 6, can tumble in wear-resisting empiecement 13 in the outer rim of blade 5, wear-resisting empiecement 13 is with the rivet rivet clasp, and is replaceable.
