Description

Technical Field

[0001] This utility model relates to the field of bulldozer blade technology, specifically a bulldozer blade with a folding structure. Background Technology

[0002] A bulldozer is an engineering vehicle equipped with a large metal bulldozer blade at the front. When the bulldozer is working, the bulldozer blade is positioned in the appropriate position under the action of the power system. Relying on the bulldozer blade, the work of digging, transporting and unloading soil can be completed.

[0003] Chinese patent provides a bulldozer combined blade, publication number CN221919578U, which includes several blade units arranged side by side from left to right in a horizontal direction. The adjacent end faces of two adjacent blade units are fixedly pressed together, and end baffle seats are respectively installed at the ends of the blade units at the left and right ends.

[0004] The above-mentioned device can select and install different numbers of blade units according to the working conditions, thereby controlling the overall length and internal blade cavity space, effectively ensuring that it is suitable for shoveling operations under multiple working conditions, and has strong overall versatility.

[0005] However, the overall structure is fixed with bolts, making it difficult to quickly adjust the amount of soil the blade can scoop as needed. The process of repeatedly twisting and adjusting the blade is quite cumbersome. Furthermore, when objects stick to the blade cavity, in order to prevent them from affecting subsequent scooping, a water pipe must be used to clean them before proceeding with the next operation. This process of stopping the machine repeatedly for cleaning significantly reduces work efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a bulldozer blade with a folding structure, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A bulldozer blade with a folding structure includes a main blade, on both sides of which are provided with mounting grooves and a sub-blade is movably mounted in the mounting grooves. An electric hydraulic telescopic rod is mounted on both sides of the rear end of the main blade.

[0009] The two electro-hydraulic telescopic rods are connected to the rear end of the sub-blade via telescopic push rods at their far ends. The two sub-blades are fixedly connected to side baffles at their far ends. The rear end of the main blade is hinged to a connecting frame. A connecting lug is provided at the center of the rear end of the main blade. A sliding rod is fixedly connected to the rear end of the sub-blade on the side away from the main blade. Limit blocks are provided on both sides of the rear end of the main blade, and the end of the sliding rod away from the sub-blade passes through both sides of the limit blocks.

[0010] Preferably, the slide bar and the limiting block are slidably connected, and the side baffle does not contact the outer side of the main blade.

[0011] Preferably, the inner bottom wall of the main blade is provided with a plurality of blade teeth arranged at equal intervals, and the blade teeth are inclined with the rear end raised.

[0012] Preferably, a mounting plate is fixedly connected to the upper front end of the main blade, and several nozzles are installed through the upper and lower ends of the mounting plate, with the top ends of the nozzles connected to each other through a transmission pipe.

[0013] Preferably, the nozzles are arranged at equal intervals on the mounting plate, and a universal joint is installed at the bottom end of each nozzle.

[0014] Preferably, the end of the transmission pipe is connected to an air supply pipe and a water supply pipe via a tee connector, and a solenoid valve is provided at the connection between the air supply pipe and the water supply pipe and the tee connector.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up a sub-shovel blade, a sliding rod, and an electric hydraulic telescopic rod to cooperate with each other, can adjust the extension length of the sub-shovel blade as needed to control the overall shoveling length, making it highly applicable. Moreover, the folding structure can improve adjustment efficiency, eliminating the need for repeated assembly and disassembly, and making it highly flexible in use.

[0017] By setting up a transmission pipe, universal joint, spray pipe, water supply pipe, solenoid valve, and air supply pipe in conjunction with the main blade, and by connecting the water supply pipe and air supply pipe to an external air pump and water pump respectively, the inner cavity of the blade can be cleaned by blowing air and spraying water when the blade is working. This prevents excessive debris from adhering to the sub-blade and main blade, thus preventing any impact on normal bulldozing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 A bulldozer blade with a folding structure includes a main blade 1, with mounting slots on both sides of the main blade 1, and a sub-blade 3 is movably mounted in the mounting slots. An electric hydraulic telescopic rod 5 is mounted on both sides of the rear end of the main blade 1.

[0025] See Figure 2 and Figure 3 Furthermore, it is found that the ends of the two electric hydraulic telescopic rods 5 that are far apart from each other are connected to the rear end of the sub-blade 3 through the telescopic push rod 6. The ends of the two sub-blades 3 that are far apart from each other are fixedly connected to the side baffles 4. The rear end of the main blade 1 is hinged to the connecting frame 2. The rear end of the main blade 1 is provided with a connecting lug 8 at the center position. The rear end of the sub-blade 3 and the side away from the main blade 1 is fixedly connected to the sliding rod 7. The rear end of the main blade 1 is provided with limit blocks on both sides. The end of the sliding rod 7 away from the sub-blade 3 passes through both sides of the limit block. The sliding rod 7 and the limit block are slidably connected. The side baffles 4 do not contact the outside of the main blade 1. The inner bottom wall of the main blade 1 is provided with several blade teeth arranged at equal intervals. The blade teeth are inclined with the rear end raised.

[0026] Specifically, according to existing technology, the main blade 1 can be installed to a suitable position on an external bulldozer via the connecting frame 2 and the connecting lug 8. Then, by activating the electric hydraulic telescopic rod 5, its telescopic push rod 6 can be extended, thereby pushing the sub-blade 3 to move away from the main blade 1. By having the sub-blade 3 extend from the side of the main blade 1, the overall length of the main blade 1 can be increased, allowing personnel to adjust it according to working conditions and construction environment, thus making it highly adaptable. At the same time, the sliding rod 7 can improve the adjustment stability of the sub-blade 3.

[0027] Example 2

[0028] See Figure 3Furthermore, based on Embodiment 1, a mounting plate 9 is fixedly connected to the upper front end of the main shovel 1. Several nozzles 10 are installed through the upper and lower ends of the mounting plate 9. The top ends of the nozzles 10 are connected to each other through a transmission pipe 11. The nozzles 10 are arranged at equal intervals on the mounting plate 9. A universal joint head 15 is installed at the bottom end of the nozzles 10. The end of the transmission pipe 11 is connected to an air supply pipe 13 and a water supply pipe 14 through a three-way connector. A solenoid valve 12 is provided at the connection between the air supply pipe 13 and the water supply pipe 14 and the three-way connector.

[0029] Specifically, the external air pump outlet can be connected to the air supply pipe 13, and the external water pump inlet can be connected to the water supply pipe 14. During use, by intermittently activating different solenoid valves 12, air and water can be delivered to the transmission pipe 11 and sprayed into the inner cavity of the main blade 1 and the sub-blade 3 through the universal nozzle 15 to clean them. This prevents excessive dirt inside the main blade 1 and the sub-blade 3 from affecting the bulldozing operation. The universal nozzle 15 is universally adjustable, and the spray angle of each universal nozzle 15 can be adjusted as needed, providing high flexibility in use.

[0030] In actual operation, the main blade 1 can be installed to a suitable position on the external bulldozer by connecting frame 2 and connecting lug 8 according to existing technology. Then, by activating the electric hydraulic telescopic rod 5, its telescopic push rod 6 can be extended, thereby pushing the sub-blade 3 to move away from the main blade 1. By extending the sub-blade 3 from the side of the main blade 1, the overall length of the main blade 1 can be increased, so that personnel can adjust it according to the working conditions and construction environment, which has high applicability. At the same time, the sliding rod 7 can improve the adjustment stability of the sub-blade 3.

[0031] The external air pump outlet can be connected to the air supply pipe 13, and the external water pump inlet can be connected to the water supply pipe 14. During use, by intermittently activating different solenoid valves 12, air and water can be delivered to the transmission pipe 11 and sprayed into the inner cavity of the main blade 1 and the sub-blade 3 through the universal nozzle 15 to clean them. This prevents excessive dirt inside the main blade 1 and the sub-blade 3 from affecting the bulldozing operation. The universal nozzle 15 is universally adjustable, and the spray angle of each universal nozzle 15 can be adjusted as needed, providing high flexibility in use.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
