Abstract
The utility model relates to a mud-free shovel, and belongs to a digging tool, which overcomes the problems the prior shovel has. The utility model consists of a shovel neck, a shovel surface and a shovel hole. The shovel neck is welded with the shovel surface and holes are arranged on the shovel surface. When the sticky clay is thrown out, the shovel holes allows the air to enter the contacting surface of the shovel and the clay rapidly based on physics principles, and thereby a positive pressure cavity is formed between the shovel and the clay; simultaneously, the contacting area of the shovel and the clay is decreased and the adhensive force of the clay and the shovel surface is greatly lowered correspondingly, thereby, the dug clay is thrown out easily and does not adhere to the shovel surface. By adopting the technical proposal, the labor intensity can be lowered greatly, the labor efficiency can be enhanced, the material cost can be reduced and the cost for tool manufacturing can be lowered. The utility model is portable and attractive, and has considerable social benefit and corporate profitability.
Description
One, technical field: the utility model relates to digging tool, especially Spade without sticking mud.
Two, background technology: conventional common spade is when excavating the little earth of humidity; there is not the phenomenon that attaches the spade surface in earth; but when mining clay humidity surpassed 40%, regular meeting produced sposh attaching surface phenomenon during spade, existed the big and low phenomenon of production efficiency of labour intensity.
Three, summary of the invention: the purpose of this utility model provides Spade without sticking mud, it has overcome the problem that present spade exists, it is by the shovel neck, shovel face and shovel hole connect, the shovel neck welds with the shovel face, the shovel hole is arranged on the shovel face, the cutting position in shovel hole and quantity are repeatedly through calculating and experiment, in use do not influence the intensity and the toughness of spade, spade shovel hole can be when excavation viscosity earth be thrown out, utilize physics principle to make air enter spade rapidly and earth connects between the face, make earth and spade produce a malleation cavity, simultaneously because the contact-making surface of spade and earth has reduced, and the adhesive force of muddy water and shovel face is also corresponding to be reduced significantly, the high earth of the viscosity of excavating, will throw out more like a cork, can not be attached to the shovel face.This spade not only is fit to excavate the high soil property of muddy water content, and suitable equally to the not high soil property of moisture content.
Owing to adopt such scheme, the utility model can significantly reduce labour intensity, save material, reduce manufacturing cost, in light weight, light and beautiful is particularly suitable for the high area of muddy water content and uses, speedily carry out rescue work and be not suitable for can significantly improving work rate under the situation of mechanized construction at floods, social benefit and business economic benefit are very considerable.
Four, description of drawings: accompanying drawing is the structural representation of Spade without sticking mud.
Among the figure 1, shovel neck 2, shovel face 3, shovel hole.
Five, embodiment: in above accompanying drawing, shovel neck 1 welds together with shovel face 2; Shovel hole 3 is arranged on the shovel face.
Claims (1)
1, Spade without sticking mud is formed by connecting by shovel neck (1), shovel face (2), shovel hole (3), it is characterized in that: shovel neck (1) and shovel face (2) weld together; Shovel hole (3) is arranged on the shovel face (2).
