Description

Technical Field

[0001] This utility model relates to the field of agricultural hoe technology, and in particular to a square cage clamp ear hoe. 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 a variety of processes to prevent the hoe plate from falling off at the weld joint with the hoe ear. This solution is specifically designed with a special structure for fixing the hoe ear of a square cage. 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 clamp ear hoe to solve the problem that the hoe ear 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 from moisture in the soil, but also because the rigid force exerted by the hoe handle on the lug can cause it to crack after prolonged use. Therefore, this design incorporates a more flexible structure to prevent the weld from cracking and, through reliable measures, to prevent the hoe lug from easily detaching.

[0007] The objective of this utility model is achieved through the following technical solution: a square cage clamping hoe, comprising a hoe plate and hoe ears disposed on the edges of the hoe plate, characterized in that:

[0008] The hoe ear has an arched doorway structure with slots at the lower left and right ends;

[0009] The hoe ear is fitted into the upper edge of the hoe plate through a slot and fixed by welding.

[0010] As a preferred technical solution of this application, a weight is also placed on the upper edge of the hoe board, so that the upper edge of the hoe board deforms when digging.

[0011] As a preferred technical solution of this application, the width between the left and right sides of the hoe ear is one-third of the width between the left and right sides of the hoe plate.

[0012] As a preferred technical solution of this application, the surface of the hoe plate is concave and tile-shaped, and the hoe plate forms a gradually rising arc structure from the lower edge to the upper edge; the hoe ear gradually rises in an arc from the direction close to the hoe plate to the direction away from the hoe plate, and the thickness of the hoe plate gradually increases from the direction close to the hoe plate to the direction away from the hoe plate.

[0013] To facilitate understanding, the working principle and core design points of this solution will be explained as follows:

[0014] (1) It should be noted that in the existing related technologies, 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 will be subjected to the reaction force of the hoe plate when digging, so the weld is easy to crack.

[0015] (2) In this scheme, a groove is made on the hoe ear, and the groove is fitted onto the upper edge of the hoe plate and then the two are welded together. During the digging process, the reaction force generated by the soil on the hoe plate is mainly offset by the groove - not by the weld. Therefore, the weld is not easy to crack, thus preventing the hoe ear from falling off the hoe plate and improving the service life of the hoe.

[0016] This invention has the following advantages: it can prevent cracking at the weld between the hoe ear and the hoe plate, thereby improving the service life of the hoe. Attached Figure Description

[0020] 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.

[0021] 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.

[0022] 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.

[0023] To address the aforementioned issues, this solution provides the following approach: The installation structure of the hoe ear and hoe plate is improved by creating a slot in the hoe ear to engage with the edge of the hoe plate, and then the two are welded together. During digging, the reaction force exerted by the soil on the hoe plate is offset by the slot, thus preventing cracking at the weld between the hoe ear and hoe plate and improving the hoe's lifespan.

[0024] 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.

[0025] See Figures 1-2 A square cage clamping hoe includes a hoe plate 10 and hoe ears 20 disposed on the edge of the hoe plate 10.

[0026] Among them, the hoe ear 20 has an arched door-shaped structure, and slots 40 are opened at the lower left and right ends of the hoe ear 20;

[0027] During installation, the slots 40 at the left and right ends of the hoe ear 20 are snapped onto the upper edge of the hoe plate 10 and then fixed by welding. When digging with the cutting edge of the lower edge of the hoe plate 10, the reaction force generated by the soil on the hoe plate 10 is offset by the slots 40, thereby preventing the weld between the hoe ear 20 and the hoe plate 10 from cracking.

[0028] The shape, size, and installation position of the hoe plate 10 and hoe ear 20 will be further explained below.

[0029] The hoe blade 10 has a concave, tile-like surface, and its surface gradually curves upwards from the lower edge to the upper edge. The hoe lugs 20 have a gradually rising arc shape from near the hoe blade to away from it, and their thickness gradually increases from near to far from the hoe blade. When swinging the hoe, the hoe blade 10 moves in a circular trajectory with the handle and arm as the radius; therefore, this structure of the hoe lugs 20 facilitates the cutting edge's entry into the ground.

[0030] Furthermore, the width between the hoe ears 20 and 10 is about one-third the width of the hoe plate 10.

[0031] In this embodiment, a weight 30 is also placed on the upper edge of the hoe plate 10, so that the upper edge of the hoe plate deforms when digging.

[0032] 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.
