Description

Technical Field

[0001] The utility model relates to the technical field of farm tools, in particular to a hoe. Background Art

[0002] Traditional hoes usually include a hoe plate and a hoe shank welded to the hoe plate. The hoe plate is usually a plate-like structure. Later, in order to increase the strength of the hoe plate, a reinforcing rib was added to the hoe plate. For example, CN201426237Y discloses a welded hoe, which includes a hoe plate and a rolled and welded hoe shank (i.e., the hoe shank). The hoe plate and the rolled and welded hoe shank are welded into one body. There is a longitudinal convex rib (i.e., the reinforcing rib) on the hoe plate that starts from the welding point of the rolled and welded hoe shank and ends at the middle of the hoe plate, and gradually becomes smaller from large; the back of the hoe plate corresponding to the longitudinal convex rib is a groove; there is a sealing plate with a size adapted to the groove opening filled in the groove and welded flush with the back of the hoe plate. This technical solution further improves the mechanical strength of the hoe plate by setting a longitudinal convex rib on the front of the hoe plate and welding a sealing plate at the groove of the rib on the back of the hoe plate, and at the same time makes the appearance of the hoe plate flat and smooth. However, this technical solution has the following problems to be solved:

[0003] (1) It is not easy for the hoe plate to shed the soil stuck to it.

[0004] (2) The weight of the hoe plate is not light enough. Content of the Utility Model

[0005] The utility model aims to provide a hoe to solve the technical problems that the soil stuck to the hoe plate is not easy to fall off or the weight of the hoe plate is not light enough in the prior art.

[0006] The technical solution of the utility model is as follows:

[0007] A hoe includes a hoe plate and a hoe shank. The upper end of the hoe plate is integrally welded with the hoe shank, and the lower end of the hoe plate is a hoe blade; the hoe plate includes a first hoe plate and a second hoe plate, and the first hoe plate is thicker than the second hoe plate; the upper end of the first hoe plate is integrally welded with the hoe shank, the lower end of the first hoe plate is integrally welded with the upper end of the second hoe plate, and the lower end of the second hoe plate is a hoe blade; a stepped surface is formed at the welding joint of the first hoe plate and the second hoe plate, and the stepped surface protrudes from the second hoe plate but does not protrude from the first hoe plate.

[0008] The following is a further limited technical solution, but it is not a limitation of the foregoing technical solution.

[0009] The lower end of the stepped surface is of the same thickness as the upper end of the second hoe plate, and the upper end of the stepped surface is of the same thickness as the lower end of the first hoe plate, and the angles between the stepped surface and the extension line of the first hoe plate and between the stepped surface and the extension line of the second hoe plate are both greater than 0° and less than 25°.

[0010] The welding joint of the first hoe plate and the second hoe plate is a straight welding.

[0011] The welding joint of the first hoe plate and the second hoe plate is an uneven welding. The welding end of the first hoe plate is concave, and the welding end of the second hoe plate is convex.

[0012] The first hoe plate, the stepped surface, and the second hoe plate gradually become thinner from the upper end to the lower end.

[0013] Reinforcing ribs are provided on the first hoe plate. The front of the reinforcing ribs protrudes in a triangular pyramid shape and extends from one end of the hoe shank to the end close to the second hoe plate; the back of the reinforcing ribs is in the shape of a triangular groove.

[0014] The height of the hoe shank is 5 - 7 cm.

[0015] The hoe shank is cylindrical, square tubular, or round-cornered square tubular.

[0016] The second hoe plate is made of 65 manganese steel.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] (1) The present utility model forms a stepped surface at the welding joint of the first hoe plate and the second hoe plate. This stepped surface forms a gradient transition with the first hoe plate and the second hoe plate, making it easier for the hoe plate to shed the adhered soil.

[0019] (2) Through the design that the first hoe plate, the stepped surface, and the second hoe plate gradually become thinner from the upper end to the lower end, the hoe of the present utility model is thinner, lighter, and sharper.

[0020] (3) On the basis of setting the reinforcing ribs, the welding strength of the hoe plate can be further enhanced by means of uneven welding, making the overall structure of the hoe plate more firm and further improving its durability. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the technical solutions and beneficial effects of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0034] Embodiment 1

[0035] As Figure 1 and Figure 3 shown, a hoe includes a hoe trousers 1, a first hoe plate 2, a second hoe plate 4 and a reinforcing rib 3.

[0036] The hoe trousers 1 are cylindrical in shape with a height of 6 cm, which is higher than the height of the hoe trousers of traditional hoes, making the connection between the hoe trousers 1 and the hoe handle more firm.

[0037] The first hoe plate 2 is made of iron plate, and the second hoe plate 4 is made of 65 manganese steel; the first hoe plate 2 is thicker than the second hoe plate 4.

[0038] The upper end of the first hoe plate 2 is integrally welded to the hoe trousers 1 in a forging and strengthening manner, the lower end of the first hoe plate 2 is integrally welded to the upper end of the second hoe plate 4 in a straight-line forging manner, and the lower end of the second hoe plate 4 is a hoe blade.

[0039] The welding joint of the first hoe plate 2 and the second hoe plate 4 forms a step surface 5. The lower end of the step surface 5 has the same thickness as the upper end of the second hoe plate 4, and the upper end of the step surface 5 has the same thickness as the lower end of the first hoe plate 2. Moreover, the first hoe plate 2, the step surface 5, and the second hoe plate 4 gradually become thinner from the upper end to the lower end and show a gradient change, so that the angle A between the step surface 5 and the extension line of the first hoe plate 2 and the angle B between the step surface 5 and the extension line of the second hoe plate 4 are both greater than 0° and less than 25°, and 10° - 20° can be preferably selected.

[0040] The front of the reinforcing rib 3 is convex in the shape of a triangular pyramid, and the reinforcing rib 3 extends from one end of the hoe trousers 1 to near one end of the second hoe plate 4; the back of the reinforcing rib 3 is in the shape of a triangular groove. The function of the reinforcing rib 3 is to make the hoe plate more firm and not easily deformed.

[0041] Embodiment 2

[0042] As Figure 2 shown, different from Embodiment 1, the lower end of the first hoe plate 2 and the upper end of the second hoe plate 4 are integrally welded by means of stamping with concave-convex lines. The lower end of the first hoe plate 2 is concave in the shape of a "ji", and the upper end of the second hoe plate 4 is convex in the shape of a "ji". The concave-convex welding method can make the overall structure of the hoe plate more firm.

[0043] Embodiment 3

[0044] Different from Embodiment 2, the hoe trousers 2 are in the shape of a square tube; the lower end of the first hoe plate 2 is concave in an arc shape, and the upper end of the second hoe plate 4 is convex in an arc shape (not shown in the figure).
