Abstract

The utility model relates to a novel concrete mixer which belongs to a vertical shaft planet forced concrete mixer. The whole machine adopts a feeding mechanism of a jzc concrete mixer with double cones, wherein, a speed reduction gearing, a clutch for a rope drum, and a feeding handling device are positioned in 90 DEG diversion at the gap of the bottom of the feeding mechanism; a machine frame is provided with a road wheel, a mop and a variable type support; a stirring mechanism uses a fixed type toothed disc, a tapered roller bearing and a regulating nut with a locking device to replace a slewing ring; a single bridge type horizontal supporting bracket is used. The utility model has the advantages of compact structure, high reliability, low cost, convenient working diversion, good manufacturability and convenient dismounting and maintenance.

Description

A kind of new concrete mixer

The utility model relates to concrete central mix plant, and particularly the improvement at vertical shaft planet forced concrete mixer designs.

Up to now, the horizontal axis forced concrete mixer has developed more perfect, though it has very strong agitating function, but owing to whipped form determines, there is the shortcoming that is difficult to avoid on the structural design, many as fragile part, service life is short, maintenance cost height, especially shaft level are installed and are caused shaft shaft end seal weak effect, and spillage is more serious.And vertical shaft planet forced mixer has solved the spillage problem fully with vertical installation, the stirring of its structure, has improved machine life.But the agitating device complex structure, the manufacturing cost height.The patent No. is that 93239676.3 " concrete mixer " done improvement on this basis.Especially adopt pivoting support to reach the purpose that simplifies the internal structure of an organization, improves agitating function and reliability on the agitating device.But the cost of pivoting support is equally very high, and the agitating device structure is not compact, and anufacturability is poor, is difficult for maintenance.Feed mechanism hydraulic pressure lift mode, the cheap degree of reliability and cost all promote structure not as good as the mechanical type that adopts on the bipyramid concrete mixer.

The purpose of this utility model is that the deficiency at prior art provides " a kind of new concrete mixer ".On the complete machine layout structure, done to improve design on agitating device and the stirring bearing support, to reach further simplified structure, further improve anufacturability and reliability, reduce cost significantly, for market provides comprehensive mechanical performance better concrete mixer.

The utility model takes following measure to realize: a kind of new concrete mixer comprises frame, feed mechanism, main shaft planetary mixer structure, water supply mechanism, electric cabinet, it is characterized in that: on integral layout, road wheel, mop and adjustable supporting are housed on the frame; Feed mechanism adopts the typing feed mechanism of jzc bipyramid concrete mixer; The fixed fluted disc of main shaft planetary mixer structure, and the adjusting nut of tight screw with lock is housed at the fluted disc upper and lower end, the vertical shaft lower end is discoid and fixedly fuse by pivot pin and connecting bolt and puddle support; The agitating device bearing support adopts single bridge-type horizontal supporting frame, have under it coupling ring and with the cylindrical shell bolted on connection.

The utility model compared with the prior art its advantage is: road wheel, mop and adjustable support are housed, the work convenient transfer on the frame.The typing feed mechanism transfer of jzc bipyramid concrete mixer is used on this utility model, particularly promote speed reduction gearing and rope roll clutch, the material loading operating means is closely as one and is loaded on gap, stock shelf bottom, compared with the prior art make the purpose that the 90-position transfer has reached reasonable Arrangement, make that complete machine structure is more simple, coordination, compactness, promote dependable performance, reduced cost.Overcome the shortcoming of hydraulic lifting mechanism.Vertical shaft planetary mixer structure is compared with pivoting support with the adjusting nut of fixed fluted disc, garden taper roller bearing and tight device with lock, and structure is more simple, compact, anufacturability is better, and cost only is 1/3rd of a pivoting support.Single bridge-type horizontal supporting frame anufacturability is good, dismantles easy to maintenance.The complete machine manufacturing cost only is 2/3rds of a prior art.

Below providing accompanying drawing further specifies in conjunction with the embodiments.Fig. 1. be a kind of structure diagram of new concrete mixer.Fig. 2. be a kind of planetary vertical-shaft rabbling mechanism sketch of new concrete mixer.Fig. 3. be a kind of planetary vertical-shaft rabbling mechanism sketch vertical view of new concrete mixer.

Road wheel 1 is loaded on the frame bottom, mop 2 is installed in the frame front end, be contained in around the frame with four adjustable supportings 3, elevating hopper 4 activities are contained on the stock shelf 5 and can move up and down along the stock shelf track, its power resources drag elevating hopper in speed reduction gearing 6 by 6 steel wire ropes that drive on the rope roll clutch 7.Promote control by promoting operating means 8 controls.Its speed reduction gearing and rope roll clutch and material loading operating means are combined as a whole and are loaded on gap, stock shelf bottom, compared with the prior art do 90.Position transfer has reached the reasonable Arrangement purpose.Fixed fluted disc 9 is contained in the bottom surface, stage casing of single bridge-type horizontal supporting frame 18, at the fluted disc upper and lower end garden taper roller bearing 10 and 11 are housed respectively, upper surface at upper end bearing 10, be that the adjusting nut 14 that tight screw 13 with lock is equipped with on main shaft 12 tops is held main shaft 12, main shaft 12 lower ends are discoid and be fixedly connected with puddle support 17 by bearing pin 15 and attachment bolt 16 and be integral.Single bridge-type horizontal supporting frame 18 its underparts have coupling ring 19, coupling ring connects with cylindrical shell 20 a usefulness number bolt 21, the main shaft upper end is driven by planetary reducer 22, puddle support 17 two ends are equipped with a pair of planet and are stirred gear 24, when puddle support 17 revolution, planet shaft 23 is realized rotation around fixed fluted disc.Be equipped with on the planet shaft 23 and stir armed lever 25 and blade.There are straight puddler 26 and scraper plate 27 in the lower end, middle part of puddle support 17.
