Abstract

The utility model relates to an agricultural spade, particularly a pointed spade. The pointed spade is composed of a spade plate and spade trousers, wherein, the spade plate is bended upwards by using the longitudinal midline of the spade plate as an axial cord, the transversal lines of the transversal profile of the spade plate form an isosceles triangle, and after the spade plate which is formed in the utility model is concave inwards, a line-shaped concave channel is formed from a trousers nose to the tip of the spade plate. Compared with the traditional agricultural pointed spades, the line-shaped concave channel which is formed from the trousers nose to the tip of the spade plate by the spade plate of the utility model enables the force receiving points of the spade plate to be concentrated on the concave channel. The concave channel plays the functions of a reinforcing rib, so the spade plate is not easy to bend when the spade plate is used, and the service life of the spade plate is improved.

Description

The point spade

The utility model relates to farm spade, particularly a kind of sharp spade.

The curved structure of tradition its spade plate of sharp spade, spade trousers bottom is commonly called as its outer rim of trousers nose and also is connected for mild arcuate structure with the spade plate, because spade trousers and spade plate generally are disposal pressed mouldings, the holding capacity of trousers nose outer rim is much smaller than the holding capacity of the above spade trousers part of trousers nose, so in practicality, the spade plate often outwards bends with trousers nose outer rim traverse, and the spade plate just fractures from here in the course of time.

The purpose of this utility model is exactly in order to overcome above-mentioned weak point of the prior art, and provide a kind of in practicality the spade plate be difficult for bending, increase the spade plate sharp spade in service life.

The purpose of this utility model is achieved in that this point spade is made up of spade plate, spade trousers, the spade plate is upwards bending of axis with its longitudinal midline, the horizontal end face transversal of spade plate constitutes isosceles triangle, therefrom after the spade plate indent of Gou Chenging from the trousers nose to the linear chase of the pointed one-tenth of spade plate.

The utility model is compared with the agricultural sharp spade of tradition, and its spade plate is the linear chase to the pointed one-tenth of spade plate from the trousers nose, and the stress point of spade plate is concentrated on this chase, this chase has played the effect of reinforcement, therefore, when using, the spade plate is difficult for bending, the service life of having improved the spade plate.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

The utility model embodiment is made up of spade plate 1, spade trousers 2, and spade plate 1 is upwards bending of axis with its longitudinal midline, and spade plate 1 horizontal end face transversal constitutes isosceles triangle, therefrom after spade plate 1 indent of Gou Chenging from trousers nose 3 to the linear chase 4 of the pointed one-tenth of spade plate.

Claims

1, a kind of sharp spade comprises spade plate, spade trousers, it is characterized in that the spade plate is upwards bending of axis with its longitudinal midline, and the horizontal end face transversal of spade plate constitutes isosceles triangle, therefrom after the spade plate indent of Gou Chenging from the trousers nose to the linear chase of the pointed one-tenth of spade plate.
