Background technology
Publication number is that the patent documentation of CN201752636U discloses a kind of culture medium of edible fungus agitator; Form by frame, motor transmission mechanism, casing, charging aperture and discharging opening, half oar formula screw; The casing cross section is to prolong the tangent line framed side wallboard on the semicircle tubbiness both sides; Rotor shaft is installed in semicircle bucket circle centre position, in the wallboard of casing both sides shower is installed, and shower is connected with water source tube; Half oar formula screw is for radially helix is dull and stereotyped; Dull and stereotyped radical length is 1/5~1/8 of a full blade radical length; Flat board is formed with being fixedly connected by several connecting rods of main shaft; Half oar formula screw radially outside the helix flat board nose circle precession direction vertical fixing to connect an axial screw line dull and stereotyped, the dull and stereotyped periphery of axial screw line is with radially the dull and stereotyped periphery of helix is concordant, axial screw line sheet width equates with helix flat board radical length radially.But that this technical scheme remains is not good at the compost mixed effect, the compost mass rate of emission waits deficiency slowly.
Summary of the invention
The utility model provides a kind of culture medium of edible fungus mixer, can improve the mixed effect of compost, improves stirring efficiency; Further effect can be improved the move horizontally ability of compost in casing, accelerates the discharge velocity of compost from discharging opening, improves the load capacity of mixer.
The technical scheme that the utility model adopts is: a kind of culture medium of edible fungus mixer, comprise casing, and rotating shaft is installed in the casing; High blade of fixed installation and low blade in the rotating shaft; High blade, low blade be the shape twisted rotary shaft in the shape of a spiral, and middle part, casing side is provided with discharging opening, and discharging opening is near bottom half.
During work, rotating shaft is rotated under power drive, drives high blade and low blade and rotates in the axle center around the shaft; High and low blade has the different radius of gyration; Can turn over the half storey up and down of the compost of lay in the casing to dial respectively and stir, and make it staggered and mix, therefore; The compost mixing velocity is fast, and efficient is high; Discharging opening is arranged on middle part, casing side; Compost is after discharging opening is discharged casing, and the compost at casing middle part reduces, and forms low-lying place; Spiral helicine blade rotates the compost that helps two ends and moves horizontally to the casing middle part, thereby can accelerate the discharge velocity of discharging opening.
The above-mentioned low blade radius of gyration is 1/2nd to 2/3rds of the high blade radius of gyration.The said radius of gyration is meant the radius of high and low blade axle center rotation around the shaft.When the low blade radius of gyration is 1/2nd to 1/3rd of the high blade radius of gyration, the mixed effect of compost is better, and mixing efficiency is preferable.
The pitch that above-mentioned low blade is identical with having of high blade, and first phase differs 180
oThe mixed effect of compost is better, and mixing efficiency is preferable.
The utility model is through fixedly having the helical form blade of the different radius of gyration in rotating shaft; Can be respectively the half storey up and down of the compost of lay in the casing be turned over to dial and stir; The staggered mixing velocity of compost is fast; Efficient is high, and helps compost and in casing, move horizontally, and can accelerate the discharge velocity of discharging opening.
The specific embodiment
Below, be described further in conjunction with the embodiment of accompanying drawing the utility model.
Fig. 1 shows a kind of embodiment of culture medium of edible fungus mixer; Comprise casing 1, rotating shaft 2 is installed in the casing 1, rotating shaft 2 is rotated under the driving of motor 6; Fixing high blade 3 and low blade 4 in the rotating shaft 2; High blade 3, low blade 4 be shape twisted rotary shaft 2 in the shape of a spiral, and middle part, casing 1 side is provided with discharging opening 5, and discharging opening 5 is near casing 1 bottom; Low blade 4 radius of gyration are 1/2nd of high blade 3 radius of gyration; Low blade 4 pitch identical with having of high blade 3, and first phase differs 180
