Description

The Combination structure of agricultural shovel body

The present invention relates to a reinforcing coupling structure of an agricultural shovel, and more particularly, a reinforcing structure of a metal blade body that is integrally insert-injection-molded on the lower side that first rubs against the ground in a shovel consisting of a handle, a handle, and a blade body used for agriculture. Its main purpose is to provide a reinforcing joint structure of the shovel blade body for agricultural shovels that can be used for a long time when moving or removing breeding excrement, soil, sand and snow, as well as improving durability and robustness.

In general, a shovel consists of a handle, a handle and a blade body, of which a handle, a handle and a blade body are each fastened with a handle, a handle, and a blade body with a handle, a handle, and a blade body with a handle, a handle and a blade body, respectively, with a handle made of metal, synthetic resin, and mixed use. It consists of a configuration that is fixed by a combination of rivets or screws in the state.

The shovel is usually used for digging the ground to move soil, etc., and for various other purposes, such as removing snow accumulated in a certain place, removing waste from livestock in a barn, or grains such as rice and barley. The shape of the shovel is used to carry the shovel, and the shape of the shovel is not used for digging the ground, but the shape of the bottom of the blade body in order to contain as much snow, cattle, pigs, barns, salt farms, fishing and grain as possible. While maintaining this flat state, the tip of the blade is not sharp and has a straight shape.

Accordingly, various types of prior art related to the reinforcing joint structure of the blade body of an agricultural shovel are known.

For example, in Korean Patent Publication No. 10-0984765 (published date: September 27, 2010), “a synthetic resin is molded by inserting a synthetic resin into the inside of a mold core, and a metal blade of a metal material is molded by insert injection molding on the blade. In farm equipment,

The metal blade is formed through a fixing groove at one end,

A fixing pin protrudes from the molding surface of the part of the mold core that forms the blade part of the farm equipment so that the blade part of the farm equipment is located inside the blade part of the farm equipment, and the fixing groove of the metal blade is inserted into the fixing pin to be fixed. The end of the mold is seated on the mold core and then molded by inserting synthetic resin into the mold core, and the fixing pin protrudes from the molding surface of the mold core to the size of 2/3 of the thickness of the blade of the agricultural equipment, and one end is fixed on the metal blade. There is a synthetic resin farming tool with a metal blade, characterized in that it protrudes with a relatively larger circumference than the groove, and the end has the same circumference as the fixing groove, and a stepped step is formed between the one end and the end of the fixing pin.”

In addition, Korean Utility Model Publication No. 20-0182592 (published date: May 15, 2000) “In a shovel (1) made of synthetic resin having a handle (5) and a storage part (4), it is attached to the tip of the storage part. The metal plate 3 is divided into a receiving part 4, an inner inlet 3a, which is a part to be inserted, and a bent part 3b to be exposed, and a plurality of openings 1 are formed in the inner inlet 3a. , There is a shovel, characterized in that the metal plate 3 is integrally injection-molded by forming a protrusion 6 extending outward in the part forming the outer periphery of the opening 1, and

In addition, Korean Utility Model Publication No. 20-0182698 (published date: May 15, 2000) “In a shovel (1) made of synthetic resin having a handle (5) and a receiving part (4), it is attached to the tip of the receiving part. The metal plate 3 is divided into a receiving part 4, an inner inlet 3a, which is a part to be inserted, and a bent part 3b to be exposed, and a plurality of openings 1 are formed in the inner inlet 3a. , There is a shovel, characterized in that the metal plate 3 is integrally injection-molded by forming a protrusion 6 extending outward in the portion forming the outer periphery of the opening 1, and

In addition, Korean Utility Model Publication No. 20-0302135 (published date: 2003.01.11.) “In a snow removal shovel, a paring that is fixedly attached to the front and rear of the lower part, which is the opposite part of the upper part of the blade in contact with the shovel. A snow removal shovel, characterized in that it comprises a means and a drainage means formed by making a hole in the blade to remove unnecessary water,

In addition, Korean Utility Model Publication No. 20-0410326 (published date: 2006.03.07.) “In a shovel formed by dividing a shovel part with a handle on the upper end and a blade part with a straight edge,

A reinforcing member is formed at the tip of the blade part, and the reinforcing member has a V shape, and a concave inlet is formed inside the reinforcing member so that it can be inserted into the tip of the blade part, and the outer tip of the reinforcing member is inside. There is a shovel in which a reinforcing member is formed on the blade, characterized in that the reinforcing member is formed by fastening the reinforcing member to the blade part with a fastening member by forming a thinner blade portion.

In addition, Korean Utility Model Publication No. 20-0443333 (published date: 2009.02.06.) “In a synthetic resin shovel (1) having a handle (5) and a receiving part (4), it is attached to the tip of the receiving part. The metal plate 3 is divided into a receiving part 4, an inner inlet 3a, which is a part to be inserted, and a bent part 3b to be exposed, and a plurality of openings 1 are formed in the inner inlet 3a. , A shovel characterized in that the metal plate 3 is integrally injection-molded by forming a protrusion 6 extending outward in the portion forming the outer periphery of the opening 1 is known.

As described above, the joint structures for reinforcing the blade body of the shovel for agriculture are known and used,

In the above Patent Publication No. 10-0984765, insert injection molding is formed so that the blade of synthetic resin is covered on the upper and lower outer peripheral surfaces of the fixing groove so that the metal blade is firmly supported and fixed on the lower surface of the shovel, so that the end of the metal blade is exposed to the lower surface. , In order to keep the metal blade firmly without separation from the shovel, the fixing groove and blade are produced so that only the end of the blade is exposed and wrapped during insert molding, but if the fixing groove is damaged by the impact transmitted to the blade during work, the entire metal blade is externally damaged. There is a defect that causes the problem to be deviated or escaped, so improvement measures are required.

In addition, in the state that the blade body is held horizontally to accommodate as much as possible, the metal blade is deformed by the specific gravity being loaded, so that the horizontal flatness of the product cannot be maintained.

In addition, in the Registered Utility Model Publication Nos. 20-0182592, 20-0182698, 20-0302135, and 20-0410326, using fixing means such as rivets or screws on the bottom of the shovel body Although a force rib in the form of a reinforcing member is formed integrally, these conventional techniques maintain a strong fastening force by receiving excessive force around the fixing means provided to fix the blade product in the form of a shovel and reinforcing member or by impact. There is a problem that it is difficult to maintain the durability for a long time due to the defect that cannot be done.

In addition, when the reinforcing structure of the metal blade provided to increase the durability of the shovel is deformed, such deformation impacts the internal synthetic resin material, causing the entire product to be deformed.

In addition, Registration Utility Model Publication No. 20-0443333 has a reinforcing member that wraps up and down in the longitudinal direction of the tip of the shovel, and then folds and fixes it, but the weight of the reinforcing member increases the weight of the product and is produced. There is a problem in that the cost increases, and when the proportion of products increases, there is a problem that the fatigue of the worker during work increases, and the problem of increasing the product unit cost is inherent, and a solution to this is required.
