Those skilled in the art will readily recognize from the following description that alternative embodiments of the illustrated structures and methods of the present utility model may be employed without departing from the principles of the present utility model.

As shown in fig. 1 and 2, a stirring device for crushing and pulping kitchen waste according to an embodiment of the present utility model includes:

a crushing shaft 1;

the sorting crushing cutter head 2 is sleeved on the crushing shaft 1, a plurality of blade supports 6 are arranged on the sorting crushing cutter head 2, the blade supports 6 are distributed and arranged along the radial direction of the sorting crushing cutter head 2, and each blade support 6 is provided with a blade;

the blades are matched with the blade supports 6, each blade is detachably connected with the corresponding blade support 6, and each blade is one of a flat blade 4 and an inclined blade 3;

the included angle between the connecting line of the central point of the sorting and crushing cutter head 2 and any point of the lower end of the blade edge of the blade and the straight line where the blade edge is located is an angle beta, when the sorting and crushing cutter head rotates anticlockwise, the angle beta is a negative angle, and when the sorting and crushing cutter head rotates clockwise, the angle beta is a positive angle.

Namely, as shown in fig. 2, a connecting line OA between a point O of the center of the classifying and crushing cutter head 2 and a point a of any point a of the lower end of the cutting edge of the blade, specifically, an extension line of the connecting line OA, that is, an angle β between a ray AC and a straight line AB where the cutting edge is located. And defines ray AC as the final edge of angle β, such that, when the sort-crushing cutterhead 2 is rotated in the clockwise direction, angle β is a negative angle; when the classifying breaker head 2 rotates in the counter-clockwise direction, the angle β is positive. The effect of this arrangement is (illustrated by way of example in fig. 2): when the stirring device works, the sorting and crushing cutter head 2 rotates anticlockwise, materials to be crushed can be thrown outwards under the action of centrifugal force, namely the materials to be crushed can be thrown to the position, close to the periphery, of the sorting and crushing cutter head 2, so that the crushing efficiency of the materials is improved, the crushing time of the materials is shortened, and the material handling capacity of the stirring device is improved. When the angle beta is positive, the blade can resist the material to be thrown outwards towards the center of the sorting and crushing cutter head 2 in the anticlockwise rotation process of the sorting and crushing cutter head 2, so that the crushing time of the material is prolonged, the material with small crushing granularity is obtained, meanwhile, the amount of the crushed material is reduced in the same time due to the prolonged stay time of the material in the crushing cavity, and finally the treatment capacity of the stirring device is reduced.

It will be appreciated that when the classifying breaker head 2 rotates clockwise, the direction of blade assembly should be changed appropriately, and the angle β should be set to be positive, and the principle of operation is similar to that of the classifying breaker head 2 rotating counterclockwise, and will not be described again here.

The blade and the blade holder 6 are detachably connected by means of screws 5 to fix the blade to the blade holder 6. The detachable connection between the two facilitates the replacement of the blade. Of course, other detachable connection modes can be adopted between the blade and the blade support 6, and the connection modes are not limited to the connection modes described above, and are not particularly limited in the application.

The appearance of crushing axle 1 is regular hexagon, and the hole of sorting crushing blade disc 2 is regular hexagon to the appearance of better matching crushing axle 1. Alternatively, the crushing shaft 1 may have a square, triangular or circular shape, for example, and the inner bore of the classifying breaker disc 2 may have a square, triangular or circular shape, for example. As long as the two shapes can be fitted together, and are not limited to the above-listed shapes.

Preferably, the sorting and crushing cutterhead 2 is provided with a plurality of blades, and the sorting and crushing cutterheads 2 are uniformly arranged along the length direction of the crushing shaft 1, and the blades on the sorting and crushing cutterheads 2 are spirally arranged along the length direction of the crushing shaft 1.

As shown in fig. 1, when two adjacent sorting and crushing cutterheads 2 are installed, a certain angle is formed, namely, the latter sorting and crushing cutterhead 2 rotates for a certain angle on the basis of the former sorting and crushing cutterhead 2, after the installation is completed, blades on the sorting and crushing cutterhead 2 are spirally arranged on a crushing shaft 1, so that different blades can beat materials from different angles, kitchen wastes and impurities in the materials can be effectively crushed, meanwhile, the arrangement mode of the blades can also push the impurities which are not completely crushed to an impurity outlet for discharge, the risk of winding the impurities on the crushing shaft 1 and the blades is reduced, and the defects that the existing stirring device is easy to wind, block and the like are eliminated.

Preferably, the flat blades 4 and the inclined blades 3 are alternately installed. The whole of the flat blade 4 is rectangular, the cross section of the blade is rectangular, at least one blade surface of the inclined blade 3 is inclined towards the side where the blade is located, such as the upper blade surface or the lower blade surface, so that the side where the blade is located has an inclination angle, and the cross section of the blade is rectangular trapezoid. When the flat blade 4 is used alone, the front impact, although the crushing effect is better, can not push the material along the axial direction, so that the waiting time of the material in the cavity of the equipment is too long, and the processing capacity is small. When the inclined blade 3 is used independently, the inclined surface impacts, so that the material stays in the cavity of the equipment for a short time, the treatment capacity is large, and the crushing effect is poor. When the two are combined and alternately installed, the processing capacity can be better adjusted, the flat blade 4 is mainly used for sorting and crushing, the inclined blade 3 has a certain inclination angle, so that not only can sorting and crushing be realized, but also an axial force can be applied to the materials by the inclination angle. Therefore, materials are subjected to relay crushing among the sorting and crushing cutterheads 2, the materials which are not crushed by the previous sorting and crushing cutterhead 2 are continuously crushed by the next sorting and crushing cutterhead 2 under the action of axial thrust of the oblique blade 4, impurities which are not completely crushed can be pushed to an impurity outlet to be discharged by the arrangement mode of the blades, the risk of winding the impurities on the crushing shaft 1 and the blades is reduced, and the defects that the existing stirring device is easy to wind, block and the like are overcome. Of course, the inclined blades 3 and the flat blades 4 on the sorting and crushing cutter head 2 can be arranged in various modes according to the needs, and the arrangement mode is not particularly limited in the application.

Further, the sorting and crushing cutterhead 2 comprises a plurality of independent units, the independent units are detachably connected, and the blade support 6 and the sorting and crushing cutterhead 2 are integrally formed. Alternatively, the sorting breaker head 2 comprises two, three, four etc. independent units. Preferably, the sorting and crushing cutterhead 2 is provided as two identical half-discs, which are connected by bolts. And, 3 blade holders 6 are uniformly formed on each half disc. Firstly, two semicircular discs are assembled into a complete sorting and crushing cutter head 2, then the assembled sorting and crushing cutter head 2 is sleeved at a proper position on the crushing shaft 1, and finally, the sorting and crushing cutter head 2 is fixed on the crushing shaft 1 through a plurality of screws 5. The above is only a preferred embodiment of the present application, and the specific arrangement of the sorting cutter head 2 may be selected according to the conditions such as the material handling capacity in practical application, and is not limited to the above arrangement.

The separation crushing cutterhead 2 is convenient to install and detach in a split design mode, when one or a plurality of blades are seriously worn, the blades can be detached and replaced independently, and the independent units of the separation crushing cutterhead 2 corresponding to the blades can be detached and replaced. The whole crushing shaft 1 is not required to be detached to replace the worn blade, so that the maintenance time is effectively shortened, and the convenience of operation is improved.

Preferably, 2 to 8 blade holders 6 are arranged on each sorting and crushing cutter head 2. Preferably, each individual unit of the classifying breaker head 2 is provided with the same number of blade holders 6, e.g. when the number of individual units is 2, 1-4 blade holders 6 are provided on each individual unit, so that each individual unit can be provided with 1-4 blades. Alternatively, the number of blade holders 6 on each independent unit of the sorting and crushing cutterhead 2 may be different, and may be set according to specific working conditions, and the number thereof is not specifically limited in this application.

Preferably, two adjacent blade holders 6 have an angle α between them, the magnitude of which is 0 ° < α+.ltoreq.180°. Optionally, the angles between the blade holders 6 on each sorting and crushing cutterhead 2 are the same, and of course, the angles may also be different, and the values of the angles are not particularly limited in this application.

Further, the angle β is 0 ° or more and 45 ° or less, and the numerical value of the angle β is not particularly limited in the present application. The included angle between the extension line of the connecting line of the central point of the sorting and crushing cutter head 2 and the point A on the blade and the blade edge of the blade is an angle beta, and the setting of the angle beta can adjust the size of the crushing granularity of the material and simultaneously ensure that the crushed material in the cavity is thrown out more easily. It will be appreciated that the manner in which the blades are mounted is related to the direction of rotation of the classifying breaker head 2, and that when the blades are mounted on the blade support 6, the orientation of the blades is in accordance with the direction of rotation of the classifying breaker head 2, as illustrated in fig. 2, and that when the direction of rotation of the classifying breaker head 2 is counter-clockwise, the blades of the blades are oriented in a counter-clockwise direction, and the angle β is a negative angle, after the classifying breaker head 2 begins to rotate, the material in the classifying breaker head 2 will be thrown to a position near the periphery of the classifying breaker head 2 due to the centrifugal force, the breaking time of the material is reduced, and the amount of material entering the cavity within the same time is increased, i.e. the equipment throughput is increased. The rotation direction of the classifying and crushing cutterhead 2 may be clockwise according to the mounting position of the blade, and the rotation direction is not particularly limited in this application.

Further, the angle of the inclined blade 3 is larger than or equal to 0 DEG and smaller than or equal to 45 deg. The size of the crushing granularity of the kitchen waste can be controlled by adjusting the inclination angle of the inclined blade 3. When the gamma angle is small, the axial force of the inclined blade 3 to the material is reduced, the material propelling speed is slow, and the material crushing time is prolonged, so that the material with small crushing granularity is obtained; when the gamma angle is large, the axial force of the inclined blade 3 to the material is large, the material propelling speed is high, and the material crushing time is shortened, so that the material with large crushing granularity is obtained. According to the different crushing granularity, the inclination angle gamma with different sizes can be selected, and the numerical value of the angle is not particularly limited in the application.

According to the utility model, the materials are crushed from different angles by different blades, so that kitchen wastes and impurities in the materials can be effectively crushed. The design of the inclined blade 3 and the flat blade 4 has a negative angle, and the setting of the negative angle can adjust the size of crushing granularity and reduce the crushing time of materials; meanwhile, the setting of the negative angle is convenient for the broken material in the cavity to be thrown out. The flat blade 4 is mainly used for sorting and crushing, the inclined blade 3 has a certain inclination angle, so that sorting and crushing can be performed, and meanwhile, an axial force can be applied to the entering materials, so that relay crushing is formed, and the materials which cannot be crushed are pushed to the end impurity discharging port along the axial direction by continuous relay. The risk that the uncrushed materials are wound on the crushing shaft 1 and the blades is reduced, and the defects that the existing crushing structure is easy to wind, block and the like are overcome.

According to the utility model, the rotation speed of the crushing shaft 1, the negative angle of the blade and the inclination angle of the inclined blade 3 are adjusted, so that the treatment capacity of the stirring device can be adjusted, and the crushing granularity of kitchen waste is controlled, thereby effectively crushing the kitchen waste into slurry and providing support for the subsequent treatment of the kitchen waste. The design of this kind of broken axle structure can be integrated with kitchen garbage sorting broken function, improves the performance and the efficiency of equipment, and simple structure moreover, the function is effective, and the modern design, the performance is comprehensive, convenient operation, practicality safety.
