Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, and in particular to a novel garden cage with a handle for digging. Background Technology

[0002] A hoe generally consists of a blade and a handle. One end of the blade is the cutting edge, and the other end is the connector. The end of the handle is fitted to the connector. There are many types of hoes, such as digging hoes and shoveling hoes. Different hoes have different styles and are subjected to different forces during operation.

[0003] Traditional hoes typically use wooden handles, which are secured to the joint with wedges. Because digging is required, the wooden handle experiences significant stress at the joint, and combined with moisture and rot, this easily leads to breakage at the joint.

[0004] Modern excavating hoes are increasingly using round steel pipes as handles, with the lower end of the handle welded to a joint. However, this method has drawbacks. Because it's an excavating hoe, the round steel pipe handle and the joint experience significant stress. After prolonged use, the handle at the joint will flatten and bend, requiring replacement. Replacing the handle usually involves desoldering, which is inconvenient; furthermore, frequent desoldering shortens the lifespan of the joint.

[0005] In addition, in existing digging hoes, the joint is welded to the thin side of the hoe blade end, which may fall off due to stress during long-term use.

[0006] Based on this, our factory has improved upon the existing digging hoes with round steel pipes as the handles to extend their service life. Summary of the Invention

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a new type of round cage-handled digging hoe, which solves the problem of the low service life of existing round steel pipe hoe handles used in digging hoes.

[0008] The purpose of this utility model is achieved through the following technical solution: a novel round cage-shaped digging hoe with handle, comprising a hoe plate, a round steel pipe hoe handle, and a wooden core;

[0009] The upper end of the hoe plate is tapered, and the tapered part has a forged integral connector with a circular connecting hole. The lower end of the hoe plate has a cutting edge.

[0010] The lower end of the round steel pipe hoe handle has a flared opening at the inner hole. The upper end of the round steel pipe hoe handle passes through the connecting hole and the lower end is welded to the connecting hole. A wooden core is inserted into the flared opening to form a full load-bearing structure.

[0011] As a preferred technical solution of this application, the flared opening is an everted opening, and the end of the wooden core has a shape that matches the flared opening, forming a structure that can be easily inserted; the wooden core has a rough surface, forming a structure that prevents it from falling off.

[0012] Furthermore, the hoe plate includes an upper plate and a lower plate; the upper plate and the lower plate are welded together to form a structure that can be subsequently detached and removed; the upper end of the upper plate has an integrally forged connector, and the lower end of the lower plate has a grinding-machined cutting edge.

[0013] Furthermore, the connector is cylindrical, and the connector and the hoe plate are integrally formed by hot rolling and forging. There is also an integrally forged inverted triangular reinforcing rib between the front of the upper plate and the side of the connector, forming a strong load-bearing structure for the hoe plate and a structure that does not deform after bearing load.

[0014] Furthermore, the thickness of the hoe plate gradually decreases from the top to the bottom, with a thickness of 4.5 cm at the top and 2 cm at the bottom.

[0015] As a preferred technical solution of this application, the lower end of the round steel pipe hoe handle is larger than the upper end, and the diameter of the round steel pipe hoe handle gradually decreases from the lower end to the upper end; the upper end of the round steel pipe hoe handle passes through the connecting hole and the lower end is stuck at the connecting hole.

[0016] Furthermore, the middle part of the round steel pipe hoe handle is fitted with a middle rubber sleeve with anti-slip function, and the tail end of the round steel pipe hoe handle is fitted with a tail rubber sleeve with anti-slip and anti-collision functions.

[0017] Furthermore, the length of the middle rubber sleeve is 20 cm and the length of the tail rubber sleeve is 15 cm, forming a structure that is easy for the palm to grip.

[0018] To facilitate understanding, the core points of this solution will be explained as follows:

[0019] I. Overall, the hoe can withstand considerable force during digging without easily being damaged, and has a long service life;

[0020] II. Specifically, the hoe blade and connector can withstand considerable force;

[0021] It should be noted that: a. In traditional digging hoes, the hoe plate and the connector are fixed by welding (the lower end of the hoe plate is the cutting edge, and the upper end is the head, which gradually narrows, with the connector welded at the head). Furthermore, the upper part of the hoe plate is relatively thin, resulting in a weak weld between the hoe plate and the connector. Over long-term use, the weld is prone to corrosion and easily detaches; b. Because the hoe plate itself is cold-rolled and relatively thin, it is prone to slight deformation during digging. After long-term use, the hoe plate cannot fully recover its original shape. Therefore, the lifespan of the hoe plate in traditional hoes is not long, and the hoe plate and connector are prone to detachment.

[0022] In this design: a. The connector and hoe plate are forged as a single piece, thus avoiding connector detachment due to corrosion; b. Furthermore, the hoe plate is hot-rolled (the connector and hoe plate are hot-rolled as a single piece), allowing for good recovery even with slight deformation; c. In addition, the hoe plate has a thickness of 4.5 cm at the top and 2 cm at the bottom, ensuring the hoe is not easily deformed; d. Reinforcing ribs are also provided between the hoe and the connector; e. Therefore, the service life of the hoe plate and connector is significantly improved.

[0023] Second, specifically, it increases the service life between the connector and the hoe handle;

[0024] It should be noted that in traditional wooden hoes, the lower end of the wooden handle is soaked by the hand during digging, and after prolonged use, the lower end of the wooden handle is very easy to break, resulting in a short service life. Now, round steel pipe hoe handles are gradually being used instead of wooden hoe handles. Because the lower end of the round steel pipe hoe handle is hollow, the digging hoe causes the lower end of the round steel pipe hoe handle to be subjected to greater compressive force, which causes the lower end of the round steel pipe hoe handle to flatten and bend.

[0025] In this design, although the hoe handle is also made of round steel pipe, the use of a wooden core inserted into the lower end of the round steel pipe hoe handle makes the lower end of the round steel pipe hoe handle a structure that can withstand radial compressive force, thereby preventing the lower end of the round steel pipe hoe handle from collapsing or bending.

[0026] The present invention has the following advantages: (1) The hoe plate and the connector can withstand a large force, the connector is not easy to fall off, the hoe plate is not easy to deform, and the service life is long; (2) The lower end of the round steel pipe hoe handle is not easy to bend or flatten, and the service life is long; (3) The lower plate can be replaced by desoldering at the blade edge that is easily worn; (4) The service life of the entire hoe is long.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] In related technologies, there are digging hoes with wooden handles and digging hoes with round steel pipe handles. With wooden handles, the lower end of the handle rots easily due to prolonged use, and the significant force applied during digging also makes it prone to breakage. In digging hoes with round steel pipe handles, the connector is fixed to the head of the hoe plate by welding, and the round steel pipe handle is fixed to the connector hole by welding. Since this type of hoe is used for digging, the weld is prone to corrosion. Under prolonged digging stress, the joint may detach from the hoe plate (due to the small weld surface between the hoe plate and the joint – limited by the structure). Furthermore, the round steel pipe handle may bend, flatten, or corrode and detach during long-term use.

[0036] To address the problems existing in current round steel hoes, this application provides a solution: ① When installing the joint between the round steel pipe hoe handle and the hoe plate, a wooden core is inserted into the bottom of the round steel pipe hoe handle, thus forming a full load-bearing structure at the bottom of the handle—making it less prone to bending or flattening; ② The joint and the hoe plate are integrally forged, and there are inverted triangular reinforcing ribs between the connector and the hoe plate. The upper end of the hoe plate is 4.5 cm thick, and the lower end is 2 cm thick, ensuring that the hoe plate is not easily deformed and providing a good load-bearing structure between the connector and the hoe plate, preventing the joint from falling off. This improves the overall service life of the digging hoe.

[0037] Based on this, the present application provides a novel circular cage-type digging hoe with a handle, referring to... Figure 1 and Figure 2 It includes a hoe board 10, a round steel pipe hoe handle 20, and a wooden core 30;

[0038] The hoe plate 10 has a cutting edge at the lower end and a head that gradually narrows at the upper end. It has an integrally forged connector 11 at the head, and a circular connecting hole is opened on the connector 11.

[0039] Among them, the round steel pipe hoe handle 20 is a round steel pipe, which is large at the bottom and small at the top, and the diameter gradually decreases from the bottom to the top; there is a flared mouth 21 at the inner hole at the bottom of the round steel pipe hoe handle 20, and the flared mouth 21 is flared; a wooden core 30 can be inserted into the flared mouth 21.

[0040] During installation, the upper end of the round steel pipe hoe handle 20 is passed upward through the connecting hole of the connector 20, and then the lower end is locked in the connecting hole (the diameter of the lower end of the round steel pipe hoe handle 20 is larger than the diameter of the connecting hole), forming a limiting knot; then the wooden core 30 is embedded into the flared mouth 21 of the lower end of the round steel pipe hoe handle 20 to form a full load-bearing structure (when digging, the lower end of the round steel pipe hoe handle 20 is supported by the wooden core 30, and the lower end of the round steel pipe hoe handle 20 is not easily flattened or bent).

[0041] The installation of the wood core 30 and connector 11 will be further explained below.

[0042] See Figure 2 The wooden core 30 has a shape that matches the flared opening 21. During installation, after the wooden core 30 is inserted into the flared opening 21, it creates a taut structure (i.e., a full load-bearing structure) at the lower end of the round steel pipe hoe handle 20. During digging, the lower end of the round steel pipe hoe handle 20 experiences greater stress. The wooden core 30 helps prevent the lower end of the round steel pipe hoe handle 20 from being flattened or bent, thereby improving the service life of the round steel hoe handle 20.

[0043] In an alternative embodiment, the round steel pipe hoe handle 20 is welded to the joint 11.

[0044] In one alternative embodiment, the wood core 30 is 20 cm long. The wood core 30 has a rough surface to form a structure that prevents it from falling off.

[0045] The structure between connector 11 and hoe plate 20 will be further explained below.

[0046] See Figure 2 The connector 11 and the hoe plate 20 are integrally hot-rolled and forged, preventing the connector 11 from detaching due to corrosion and rust during use. Furthermore, the connector 11 and the hoe plate 20 both feature integrally hot-rolled and forged reinforcing ribs 12 (the reinforcing ribs are in an inverted triangular shape, wider at the top and narrower at the bottom). Additionally, the upper part of the hoe plate 20 is 4.5 cm thick, further ensuring the strength at the connection point between the connector 11 and the hoe plate 20. This ensures that the connector 11 can withstand very large forces, extending its service life.

[0047] The structure of the hoe plate 20 will be further explained below.

[0048] The hoe plate 20 has a thickness of 4.5 cm at the top and 2 cm at the bottom (excluding the cutting edge), ensuring that it is not easily deformed during digging. Because the hoe plate 20 is hot-rolled and forged, even if minor deformation occurs, it is easily restored to its original shape.

[0049] Furthermore, the hoe plate 10 includes an upper plate 13 and a lower plate 14. The upper end of the upper plate 13 has an integral connector 11, and the lower end of the lower plate 14 has a cutting edge produced by a grinding machine. If the cutting edge chipps or wears, the lower plate 14 can be removed by desoldering and then replaced with a new lower plate 14 (without having to reforge the entire hoe).

[0050] The following is a further explanation of the round steel pipe hoe handle 20.

[0051] The round steel pipe hoe handle 20 is wider at the bottom and narrower at the top, with the diameter gradually decreasing from the bottom to the top. When installing the round steel pipe hoe handle 20 to the connector 11, first pass the upper end of the round steel pipe hoe handle 20 through the connector hole, and then continue to move the round steel pipe hoe handle 20 upwards until the lower end is locked in the connector hole. During the hoeing process, even if the wooden core 30 falls off, the hoe plate 10 remains at the end of the original steel pipe hoe handle 20, preventing the hoe plate 10 from falling off and injuring people.

[0052] Furthermore, an anti-slip rubber sleeve 22 is provided in the middle, and an anti-collision rubber sleeve 23 is provided at the tail of the round steel pipe hoe handle 20.

[0053] Furthermore, the middle rubber sleeve 22 is 20 cm long, and the tail rubber sleeve 23 is 15 cm long. For the average person, these sleeve sizes are generally suitable for gripping.

[0054] 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.
