TECHNICAL FIELD

[0001] The utility model relates to excavating tool technical field, concretely is a kind of composite spade with wear-resistant reinforcing structure. BACKGROUND

[0002] In the excavating tool technical field, spade as commonly used tool, is widely used in various excavating, shovel carrying operation. Traditional spade is mostly made of single material, such as all-metal spade or all-plastic spade. However, these traditional spades have some problems in the process of use.

[0003] Although all-metal spade has higher structural strength and wear resistance, its weight is larger, and long-time use can easily make operator feel tired, and metal spade is easy to produce larger noise and vibration when contacting with ground or other hard objects, which causes adverse effects on operator and environment. While all-plastic spade is light and has small noise, but its structural strength and wear resistance are relatively poor, and it is easy to appear wear, deformation or even damage in the process of use, thereby reducing the service life and operation efficiency of spade.

[0004] In order to solve the above problems, people begin to try to use composite material to make spade, so as to improve the comprehensive performance of spade. Composite material spade combines the advantages of different materials, such as the lightness of plastic and the high strength and wear resistance of metal, thereby improving the defects of traditional spade to some extent. However, the existing composite material spade still has some deficiencies in structure design and material selection, such as uneven structural strength and poor wear resistance, which limits its application in some special working environments. Therefore, it is necessary to develop a composite spade with wear-resistant reinforcing structure to improve the structural strength and wear resistance of spade, while maintaining lightness and good use experience. The utility model is proposed based on this demand. SUMMARY

[0013] Compared with the traditional single-material shovel, the composite shovel with the wear-resistant reinforcing structure has obvious advantages and beneficial effects, which are embodied in the following aspects:

[0014] (1) The structural strength is significantly improved: through the combination of the plastic shovel body and the bent metal sheet metal part, the composite shovel of the utility model forms a more solid structure at the working position. The plastic shovel body provides basic shape support and lightness, and the bent metal sheet metal part enhances the structural strength of the shovel blade part, so that the shovel is not easy to deform or damage when bearing a large digging force, and the service life of the shovel is prolonged.

[0015] (2) The wear resistance is greatly improved: the bent metal sheet metal part as a reinforcing component of the shovel blade part has high hardness and wear resistance. When contacting the ground or other hard objects, the metal part can effectively resist wear and tear, reducing the wear of the shovel blade part, thereby maintaining the sharpness and work efficiency of the shovel.

[0016] (3) Easy to maintain and replace: since the bent metal sheet metal part and the plastic shovel body are connected in a detachable manner, when the shovel blade part is severely worn due to long-term use, the user can conveniently replace the new metal part without scrapping the entire shovel. This not only reduces the use cost, but also improves the sustainable use of the shovel.

[0017] (4) Light weight and low noise: the use of plastic shovel body greatly reduces the overall weight of the shovel, enabling the operator to reduce fatigue during long-term operation. At the same time, the combination of plastic material and metal parts also effectively reduces the noise and vibration generated by the shovel during operation, providing a more comfortable working environment for the operator.

[0018] (5) Strong adaptability: the composite shovel of the utility model is designed flexibly, and appropriate plastic shovel body and metal parts can be selected for combination according to different operation requirements, so as to meet the diversified digging and carrying requirements.

[0019] In summary, the composite shovel with wear-resistant reinforcing structure of the utility model has significant beneficial effects in improving structural strength, wear resistance, maintenance convenience, reducing weight and noise, and adaptability, and brings new progress and development to the field of digging tools.

[0028] The plastic shovel body 1 comprises an integrally formed bottom plate 5 and side plate 6, the bottom plate and the side plate form a containing groove 7, the upper surface of the bottom plate is provided with a plurality of upwardly arched reinforcing ribs in parallel, wherein the reinforcing ribs comprise a first rib 8 and a second rib 9, the first rib is arranged at the middle part of the plastic shovel body and extends from the bottom of the inner shovel surface to the top of the inner shovel surface, and the second rib is arranged on both sides of the first rib; by arranging the reinforcing ribs in the plastic shovel body during design, especially the layout of the first rib and the second rib, the overall structural strength of the shovel is effectively enhanced. The first rib is arranged at the middle part of the plastic shovel body and plays a main supporting role, and the second rib is arranged on both sides of the first rib, further dispersing the stress received by the shovel during operation, preventing the shovel from being deformed or damaged due to excessive stress. The bottom plate 1 is provided with a recess 10 corresponding to the position of the reinforcing ribs on the lower surface, and the bent metal plate is provided with a clamping part 11 matched with the recess; through the cooperation of the recess and the clamping part, the firmness and wear resistance of the blade part are further enhanced.

[0029] The bent metal plate and the plastic shovel body are connected through a bolt 12, ensuring the close cooperation and stable connection between the two. This connection method is not only simple and easy to operate, but also can withstand a large external force, preventing the shovel from failing due to loose connection during use. At the same time, the bolt connection is convenient for the user to disassemble and replace, improving the maintenance convenience of the shovel.

[0030] The cross section of the bent metal sheet part is U-shaped, and the bent metal sheet part comprises a first arc-shaped plate 13, a second arc-shaped plate 14 and a third arc-shaped plate 15 connected in sequence, wherein the first arc-shaped plate, the second arc-shaped plate and the third arc-shaped plate form a clamping groove 16, the first arc-shaped plate is installed on the upper surface of the blade part, and the third arc-shaped plate is installed on the lower surface of the blade part, so that the metal part can better fit the upper and lower surfaces of the blade part and form a more compact clamping groove structure. During operation, the metal part can more effectively resist wear and protect the blade part from damage, thereby prolonging the service life of the shovel. In addition, the bent metal sheet part with a U-shaped cross section not only improves the wear resistance of the shovel, but also enhances the structural strength. The arc-shaped design of the metal part can better disperse the stress received during operation and prevent the shovel from being damaged due to stress concentration. At the same time, the close fit between the metal part and the plastic shovel body further enhances the overall structural strength of the shovel, enabling it to withstand greater digging force.
