Abstract
The utility model provides a front pump cover of a mortar pump. The front pump cover comprises a cover body, wherein the outer end of the cover body is provided with an outer flange, an inner flange is arranged on the middle end of the cover body, and the outer diameter of the outer flange is smaller than that of the inner flange; the outer diameter of the inner end of the cover body is matched with the inner diameter of the mortar pump; the inner flange is connected with the cover body through a wedged groove and a wedge which are matched with each other; the outer flange is connected with the cover body through the wedged groove and the wedge which are matched with each other. The front pump cover is provided with the inner flange and the outer flange, a working hole slot is machined in the inner cavity of each flange, a technological hole is machined in the end surface of each flange, and the inner flange and the outer flange are molded to form a whole body, so that the strength of the pump cover is greatly improved, and the corrosion resistance of the pump cover is enhanced. The front pump cover of the mortar pump is simple in structure, light in weight and low in cost.
Description
Technical field
The utility model relates to a kind of pump cover, relates in particular to a kind of mortar pump front pump cover.
Background technique
The front pump of mortar pump is stamped two kinds of forms at present, a kind of is overall plastic form, another kind is the plastic lining form, and the front pump cover of overall plastic form can only be used at some little pumps owing to be subjected to the impact of intensity, the front pump cover of plastic lining form uses at the pump of all size, but the front pump cover wear resistant corrosion resistant of this form is subjected to the restriction of plastic layer, if the plastic layer mill leaks, medium corrodes cast iron soon, cause front pump cover to damage, and the front pump cover cost compare of plastic lining form is high.
The model utility content
The purpose of this utility model is for problems of the prior art, and a kind of mortar pump front pump cover is provided.
Mortar pump front pump cover of the present utility model comprises lid, and the outer end of lid is provided with outward flange, and the middle-end of lid is provided with inner flange, and the external diameter of outward flange is less than inner flange; The external diameter of lid the inner and the internal diameter of mortar pump are suitable.
Described inner flange is connected with lid by the cooperation of wedge slot, chock.
Described outward flange is connected with lid by the cooperation of wedge slot, chock.
The relative prior art of the utility model has the following advantages:
1, front pump cover of the present utility model is provided with inner flange and outward flange, has processed worker's hole slot at the inner chamber of flange, has processed auxiliary hole at end face, by being molded into an integral body, has greatly improved the intensity of pump cover, has strengthened corrosion resistance.
2, mortar pump front pump cover of the present utility model is simple in structure, lightweight, and cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of outward flange.
Fig. 3 is the structural representation of inner flange.
Embodiment
Below in conjunction with accompanying drawing mortar pump front pump cover of the present utility model is described in further detail.
Such as Fig. 1, Fig. 2, mortar pump front pump cover shown in Figure 3, comprise lid 3, the outer end of lid 3 is provided with outward flange 1, and the middle-end of lid 3 is provided with inner flange 2, and the external diameter of outward flange 1 is less than inner flange 2; The external diameter of lid 3 the inners and the internal diameter of mortar pump are suitable; Inner flange 2 is connected with lid 3 by the cooperation of wedge slot, chock, and outward flange 1 is connected with lid 3 by the cooperation of wedge slot, chock.
At the processing wedged groove of flange inner chamber, drill through the hole on the end face, the form in hole is large on one side, on one side little, the hole communicates with wedge slot.Plastics can be embedded in these wedge slots and the hole when mold pressing like this, prevent in cast iron suction flange and plastics layering.The outward flange 1 that processes is fixed on the mold bottom die by set screw, the inner flange 2 that processes is fixed on the mold top holder compression molding by set screw.
Experimental Comparison such as the following table of the utility model and plastic lining pump cover corrosion and wear resistance wearability:
