The invention relates to devices for mixing a multicomponent material into a homogeneous mass and can be used in agriculture and other industries.

Known mixers (AS USSR Ns 611656, cl. B 01 F 7/08, 1983), the working body of which is one or more screws. Such mixers are bulky and energy intensive.

Mixers are also known (E.I. Reznik, Kormotsekhi on a farm. M .: Rosselkhozizdat, 1980, pp.83-86), containing working bodies located along helical surfaces. However, these devices have low productivity and high metal consumption.

The closest in technical essence and the achieved result is the design of the mixer (as. USSR No. 528941, cl. B 01 F7 / 04, 1972), comprising a housing, inside which is placed a hollow shaft, along which stands with blades are located. Racks are rigidly connected with gear elements. However, the above construction is not sufficiently effective and unreliable.

The aim of the invention is to intensify the mixing process and ensure trouble-free operation of the mixer.

The cauldron can be achieved by the fact that in the mixer, which contains a housing with loading and unloading windows, inside which is placed a hollow shaft, along which stands with blades rigidly connected to gear elements interacting with cutting of a movable rod located inside the shaft, gear elements mounted on the shaft pivotally, and the rod is made in the form of a rail mounted with the possibility of reciprocating motion. In addition, the blades are made of elastic material.

When searching for the applicant, no technical solutions were found with features similar to the distinctive features of the proposed invention, and therefore it can be concluded that the technical solution corresponds to the feature. Significant differences.

Figure 1 shows the mixer; figure 2 - working bodies, the cut. The mixer includes a housing 1 with a boot 2 and unloading 3 Windows. In case 1 there is a hollow shaft 4 on which racks 7 are fixed on brackets 6 with the help of hinges 5. At one end of the racks 7 resilient mixing vanes 8 are located, while others have toothed elements 9. Inside shaft 4 there is a rod 10 in the form of a rack with the possibility of reciprocating motion which is in constant contact with the gear elements 9 of the uprights 7.

Works mixer as follows.

Through the loading window 2, the original multicomponent mixing material is loaded into the mixer housing 1. Racks 7 with blades 8, the entrance to the layers of the mixed material, capture it and drag along the axis of the shaft 4. In view of the fact that inside the shaft 4, there is a rod 10 in the form of a toothed rack that reciprocates, and the ends of the racks 7 have gear elements 9, the material being mixed acquires additional movements around the hinges 5 to one and the other side. As a result of this complex movement of the material being mixed, the mixing process is intensified and its quality is improved. Moreover, due to the fact that the blades 8 are made elastic, in the process of work they acquire low-frequency auto-oscillations, which

they increase at the exit of the working body and the layer of mixed components, which also contributes to the intensification of mixing, self-cleaning of the working parts of the mixer and the reduction of energy consumption. Besides

Moreover, when meeting a lump of mixed material of increased hardness, the blade 8 deflects, bypasses the obstacle and returns to its original position. Such movements further enhance the self-oscillation process and contribute to improving the quality of mixing, as well as ensure trouble-free operation of the mixer. After completion of work, the stirred material is removed from housing 1.

mixer through the discharge window 3.

The use of the invention will allow to intensify the mixing process, improve its quality and ensure trouble-free operation of the mixer.

Claims (2)
