Description

Technical Field

[0001] This utility model relates to the field of agricultural hoe technology, and in particular to a square cage-shaped hoe with covered ears. Background Technology

[0002] Agricultural hoes consist of a hoe plate and a hoe handle. The hoe plate is curved, and a cutting edge is ground at the lower edge of the hoe plate. A hoe lug is usually provided at the upper edge of the hoe plate. The wooden hoe handle is assembled to the hoe lug using a clamp.

[0003] When making a hoe, the hoe plate and the hoe lugs are usually forged separately, and then the hoe lugs are welded to the upper edge of the hoe plate. However, when hoeing, the hoe is in contact with the moisture in the soil for a long time, which can easily cause rust and corrosion at the weld between the hoe lugs and the hoe plate. After prolonged use, the weld may fall off.

[0004] Therefore, based on customer feedback, our company has designed various methods to prevent the hoe plate from detaching from the welded joint with the hoe ear; and this solution protects the cage ear design. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a square cage-shaped hoe with ear flaps, which solves the problem that the hoe ears and hoe plate are easy to fall off at the weld.

[0006] It should be noted that the weld between the hoe blade and the hoe lug is prone to detachment. This is not only due to corrosion caused by the weld coming into contact with moisture in the soil, but also because the rigid force exerted by the hoe handle on the hoe lug can easily cause the weld to crack after prolonged use.

[0007] Therefore, this design features a relatively flexible structure, making the weld joint less prone to tearing; and through reliable results, it prevents the hoe ear from easily falling off.

[0008] The purpose of this utility model is achieved through the following technical solution: a square cage-shaped hoe with ears, including a hoe plate, the lower edge of the hoe plate being a cutting edge, and the upper edge being provided with hoe ears; The hoe ear has an arched door-shaped structure, with an integral outward expansion at the lower left and right ends of the hoe ear; The upper edge of the hoe plate has inclined shoulder structures at both ends, and an outwardly expanding mounting groove is opened on the outwardly expanding part; the shoulder structure is adapted to be inserted into the mounting groove and fixed by welding, forming a structure in which the reaction force generated by the hoe plate when digging is resisted by the shoulder structure at the mounting groove.

[0009] As a preferred technical solution of this application, the shoulder structure is an arc-shaped angle, and when digging, the mounting groove exerts a downward force on the arc-shaped angle.

[0010] As a preferred technical solution of this application, the shoulder structure is an inclined chamfer, and when digging, the mounting groove exerts a downward force on the inclined chamfer.

[0011] As a preferred technical solution of this application, a brace is also placed on the upper edge of the hoe ear to form a structure that prevents the upper edge of the hoe ear from deforming.

[0012] As a preferred technical solution of this application, the surface of the hoe plate is concave in the shape of a tile, and the hoe plate forms a gradually rising arc structure from the lower edge to the upper edge.

[0013] Furthermore, the hoe ear has a gradually curved structure that rises from the end near the hoe plate to the end away from the hoe plate.

[0014] Furthermore, the thickness of the hoe ear gradually increases from the end near the hoe plate to the end away from the hoe plate.

[0015] This utility model has the following advantages: the weld between the hoe ear and the hoe plate is not prone to cracking, thus improving the service life; Specifically, in the existing technology, the hoe ear is fixed to the hoe plate by welding. During the long-term use of the hoe, the weld is gradually corroded by the moisture in the soil. During the digging process, the weld is subjected to the reaction force of the hoe plate digging, so the weld is easy to crack. In this solution, the installation structure of the hoe ear and hoe plate is improved so that the hoe ear is wrapped around the left and right corners of the edge of the hoe plate through the installation groove. When digging, the reaction force generated by digging is offset by the installation groove and the edge of the hoe plate (rather than offset by the weld). This can avoid cracking at the weld and thus improve the service life of the hoe. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0018] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this utility model is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] It should be noted that in existing related technologies, the hoe ear is fixed to the hoe plate by welding. During the long-term use of the hoe, the welded joint is gradually corroded by the moisture in the soil. During the digging process, the welded joint is subjected to the reaction force of the hoe plate digging, so the welded joint is prone to cracking.

[0020] To address the aforementioned issues, this solution offers the following approach: The installation structure of the hoe lugs and hoe plate is modified so that the hoe lugs are secured to the left and right corners of the hoe plate's edges via mounting grooves. During digging, the reaction force generated is offset by the mounting grooves and the edges of the hoe plate (rather than by the welded joints), thus preventing weld cracking and extending the hoe's lifespan.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] See Figures 1-4 A square cage-shaped hoe with ear flaps includes a hoe plate 10, the lower edge of the hoe plate 10 being a cutting edge, and the upper edge being provided with hoe ears 20. Among them, the hoe ear 20 has an arched door-shaped structure, and has an outward expansion 21 at the lower left and right ends of the hoe ear 20. The outward expansion 21 is integrally formed with the hoe ear 20. In addition, an installation groove 21 is opened on the inner side of the outward expansion 21. Among them, there are inclined shoulder structures 11 at the left and right ends of the upper edge of the hoe plate 10; When the hoe ear 20 is installed on the hoe plate 10: the mounting groove 21 of the outward expansion 21 is fitted into the shoulder structure 11 and then fixed by welding; When digging, the cutting edge of the hoe plate 10 contacts the ground. The hoe plate 10 is subjected to the reaction force of the ground and this reaction force is transmitted to the mounting groove 21 through the shoulder structure 11 on the upper edge of the hoe plate 10. That is, the mounting groove 21 acts as a barrier to the shoulder structure 11. In other words, the force during digging is mainly offset by the blocking of the shoulder structure by the mounting groove 21, rather than by the welded structure. This allows the welded structure to crack due to digging, thereby improving the service life of the entire hoe.

[0023] The shoulder structure 11 will be further explained below.

[0024] There are several ways to design the shoulder structure 11: for example, Figure 3 As shown, the shoulder structure 11 has an arc-shaped angle 1101. When digging, the mounting groove 2101 exerts a downward force on the arc-shaped angle 1101. Or, for example, Figure 4 As shown, the shoulder structure 11 has an inclined chamfer 1102. When digging, the mounting groove 2101 exerts a downward force on the inclined chamfer 1102.

[0025] The shape and structure of the hoe plate 10 and hoe ear 20 will be further explained below.

[0026] Regarding the hoe blade 10: the surface of the hoe blade 10 is concave and tile-shaped, and the hoe blade 10 forms a gradually rising arc structure from the lower edge to the upper edge. Since the hoe blade 10 moves in a circular trajectory with the handle and arm as the radius when swinging the hoe during digging, this structure of the hoe blade 10 is conducive to the blade edge entering the ground.

[0027] As for the hoe lug 20, the hoe lug 20 has a gradually curved structure that rises from the end near the hoe plate 10 to the end away from the hoe plate 10. Similarly, when swinging the hoe, the hoe plate 10 moves in a circular trajectory with the hoe handle and arm as the radius, so this structure of the hoe lug 20 is conducive to the blade edge entering the ground.

[0028] Furthermore, the thickness of the hoe ear 20 gradually increases from the end near the hoe plate 10 to the end away from the hoe plate 10, thereby increasing the strength of the hoe ear 20.

[0029] The following section further explains the installation between the hoe ear 20 and the hoe plate 10. A brace 30 is also placed on the upper edge of the hoe ear 20 to form a structure that prevents deformation of the upper edge of the hoe ear.

[0030] The above embodiments only illustrate preferred implementation methods, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
