[0025] See Figures 1 to 3, A bulldozer blade assembly, comprising: a bucket 100 and two chain meshes 200. Among them, the bucket 100 is used to be installed on a bulldozer; one side of the chain mesh 200 is movably arranged on the bucket 100. A moving rod 210 arranged vertically is connected between the two chain meshes 200. The moving rod 210 is connected with a driving assembly for driving its movement. When the moving rod 210 moves towards the side away from the bucket 100, the two chain meshes 200 are folded relative to the bucket 100 to form an inclined guiding structure.
[0026] For the bulldozer blade assembly with the above structure, when the bulldozer encounters large sundries such as wooden boards or big stones, the driving assembly drives the moving rod 210 to move towards the side away from the bucket 100, so that the two chain meshes 200 are folded relative to the bucket 100, thereby making the chain meshes 200 form an inclined guiding structure. Then the bulldozer continues to move, and the large sundries can move towards both sides of the bucket 100 under the guidance of the chain meshes 200, finally making the large sundries away from the moving route of the bulldozer, so as to reduce the influence of large sundries on the work of the bulldozer. When the chain meshes 200 are not needed, the driving assembly drives the moving rod 210 to move towards the side close to the bucket 100, so that the chain meshes 200 are unfolded relative to the bucket 100, thereby enabling the chain meshes 200 to adapt to the working surface of the bucket 100, which is beneficial to reducing the influence of the chain meshes 200 in the non-working state on the work of the bucket 100. Among them, when encountering the working condition of sticky large chunks of soil, the chain meshes 200 can also cut the large chunks of soil, so as to achieve the effect of breaking up the soil, which is beneficial to the bulldozer to move better for bulldozing work.
[0027] See Figures 1 to 3 , Further, the driving assembly includes a cylinder 300 and two push rods 310. The bucket 100 includes a mounting frame 110. The cylinder 300 is arranged on the mounting frame 110. The two push rods 310 are respectively arranged at both ends of the moving rod 210. The telescopic end of the cylinder 300 is connected to the push rod 310 located above. The bucket 100 is provided with a guiding hole that cooperates with the push rod 310 located below. Specifically, the cylinder 300 is a double-acting pneumatic actuator. By changing the output direction of the air source through a steering valve, the moving rod 210 can reciprocate relative to the bucket 100, thereby driving the two chain meshes 200 to deflect relative to the bucket 100 to the folded or unfolded state. It can be understood that a fixing rod is connected between the two push rods 310, so that the two push rods 310 can form a whole to move synchronously. The push rod 310 located below cooperates with the guiding hole, so that the moving rod 210 can translate relative to the bucket 100, thereby avoiding the deviation of the moving rod 210 during the movement and affecting the folding or unfolding of the chain meshes 200. In some embodiments, the cylinder 300 can also be replaced by a hydraulic cylinder, so as to provide a greater power output for the push rod 310, which is beneficial to pushing the large sundries away from the chain meshes 200, and details are not described herein.
[0028] SeeFigure 1 Furthermore, a limiting member 311 is provided on the lower push rod 310. The bucket 100 is located between the moving rod 210 and the limiting member 311, so as to prevent the lower push rod 310 from detaching from the bucket 100 by using the limiting member 311, which is beneficial to ensuring the use of the push rod 310. It can be understood that the limiting member 311 can be a mounting block welded to the push rod 310 or a nut threadedly connected to the push rod 310, which will not be elaborated here.
[0029] See Figure 1 and Figure 3 Furthermore, the mounting frame 110 includes four first rod bodies 111 distributed in a rectangle. The first rod bodies 111 are used to be assembled on the bulldozer. A second rod body 112 is connected between the two upper first rod bodies 111, and the cylinder 300 is mounted on the second rod body 112. Specifically, the four first rod bodies 111 can be connected to the front end of the bulldozer, so that the power generated by the movement of the bulldozer is evenly distributed to the four first rod bodies 111, which is beneficial to the bucket 100 to perform earthmoving work better. Among them, the cylinder 300 can be fixed to the second rod body 112 by bolts, so that the second rod body 112 provides an installation position for the cylinder 300. In some embodiments, a third rod body 113 is connected between the two lower second rod bodies 112. The third rod body 113 is provided with a fixing plate, and the fixing plate is provided with a first through hole. One end of the lower push rod 310 movably passes through the first through hole, so that the fixing plate can provide a guiding function for one end of the push rod 310. In addition, in order to prevent the upper push rod 310 from shifting, a fixing block 101 is provided on the upper end surface of the bucket 100, and the fixing block 101 is provided with a second through hole through which one end of the push rod 310 can movably pass.
[0030] See Figures 1 to 3 Furthermore, mounting rods 120 are vertically arranged on both sides of the bucket 100. A plurality of elastic members 130 are connected between the mounting rods 120 and the chain net 200, and the plurality of elastic members 130 are spaced apart along the length direction of the mounting rods 120. Specifically, during use, when the moving rod 210 moves away from the chain net 200, the chain net 200 deflects relative to the mounting rod 120 and stretches the elastic members 130, so as to increase the moving area of the chain net 200 by using the elastic members 130, so that the two chain nets 200 can be folded with a smaller included angle, which is beneficial to large sundries to deviate from the bucket 100 under the guidance of the chain net 200. When the chain net 200 is not needed, the elastic members 130 recover their deformation, so as to be able to additionally provide an elastic force for the chain net 200 to reset and reduce the driving load of the driving assembly.
[0031] See Figure 2, Further, the elastic member 130 is a spring. One end of the spring is connected with an installation ring 131 which is fixedly arranged on the installation rod 120, and the other end of the spring is connected to the chain mesh 200. Specifically, the installation ring 131 can be fixed to the installation rod 120 by welding, and the spring and the installation ring 131 can be integrally formed by injection molding. Among them, the spring can also be replaced with other rubber or plastic parts with elastic deformation ability, which will not be elaborated here.
[0032] See Figures 1 to 3 , Further, the bucket 100 includes two mounting plates 140 spaced apart vertically. Both ends of the mounting rod 120 are threadedly engaged with the corresponding mounting plates 140 respectively, which facilitates people to improve the installation efficiency of the mounting rod 120 and is also beneficial for people to disassemble the mounting rod 120 subsequently to replace the chain mesh 200.
[0033] See Figure 1 , Further, the chain mesh 200 includes a plurality of steel wires arranged horizontally and vertically in a crisscross manner, and the plurality of steel wires define a plurality of grid units for partitioning. Specifically, in the working condition of encountering large chunks of sticky soil, the grid units formed by the plurality of steel wires can cut the large chunks of soil, so as to achieve the effect of dispersing the soil, which is beneficial for the bulldozer to move better for earthmoving work. It can be understood that the chain mesh 200 can adopt the existing stainless steel mesh belt for conveying, which will not be elaborated specifically.
[0034] Further, the grid unit is a square grid, a rectangular grid or a parallelogram grid.
[0035] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
