Description

Technical Field

[0001] This utility model relates to the field of automatic control blade technology for bulldozers, specifically to an automatic control blade structure for bulldozers. Background Technology

[0002] The automatic control blade for bulldozers is an advanced technological device applied to bulldozer equipment. It mainly uses sensors to monitor the working status of the bulldozer, ground conditions, and blade position in real time. This data is then transmitted to the control system, which analyzes and processes it according to preset working parameters and operational requirements. The control system then precisely and automatically adjusts the blade's height, angle, and other movements, enabling the blade to adapt to different terrain conditions and operational needs. This achieves efficient and precise bulldozing operations, reduces errors from manual operation, improves work efficiency and quality, and also reduces the labor intensity of operators.

[0003] Bulldozers typically operate in complex and harsh environments such as construction sites, mines, and farmland. The blades need to come into contact with various hard materials, such as rocks and frozen soil. During bulldozing and shoveling, the blades are subjected to enormous pressure and friction. Being in such a high-intensity abrasion environment for a long time makes the blades prone to wear, deformation, and other losses. The blades are usually fixed to the blade body by welding. Although welding provides a strong connection, it requires cutting the weld seam when replacing the blades, which is difficult to operate and can easily damage the blade body. Therefore, we propose an automatic control blade structure for bulldozers. Utility Model Content

[0004] The purpose of this invention is to provide an automatic control blade structure for bulldozers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic control blade structure for a bulldozer, comprising a blade body, a limiting structure on the surface of the blade body, the limiting structure comprising a frame, a plurality of bolts mounted on the surface of the frame, the frame being mounted on the surface of the blade body by bolts, a rotating shaft being rotatably connected to the surface of the frame, a reversible cutter head being fixedly connected to the arc surface of the rotating shaft, circular grooves being provided on both sides of the reversible cutter head, and fixing bolts being inserted on both sides of the frame, the size of the fixing bolts being adapted to the size of the circular grooves.

[0006] The effects achieved by the above components are as follows: through the design and operation of the above limiting structure, the reversible cutter head can be used on both sides by rotation, which extends the service life of the blades, reduces the operating cost, improves the operating efficiency and quality of the bulldozer, and provides strong support for engineering construction.

[0007] Preferably, extension plates are fixedly connected to both sides of the frame, and pins slide through the surface of the extension plates, with the pins passing through the fixing bolts.

[0008] The effect achieved by the above components is that the pin passes through the fixing bolt and is inserted into the fixing bolt, thereby ensuring that the fixing bolt will not easily come out of the round groove, further stabilizing the position of the reversible cutter head.

[0009] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the extension plate, respectively.

[0010] The effect achieved by the above components is that the spring prevents the pin from coming out of the fixing bolt.

[0011] Preferably, an extension arm is fixedly connected to the surface of the frame, and a baffle is fixedly connected to the end of the extension arm near the reversible cutter head. The size of the baffle is larger than the size of the circular groove.

[0012] The effect achieved by the above components is that the extension arm fixedly connected to the frame surface and the baffle at one end also play an important role in preventing the circular groove from being exposed and entering the soil.

[0013] Preferably, a limiting plate is fixedly connected to the arc surface at one end of the rotating shaft, and two fixing plates are fixedly connected to the surface of the frame.

[0014] The effect achieved by the above components is that the limiting plate fixedly connected to the arc surface of one end of the rotating shaft and the two fixing plates fixedly connected to the surface of the frame cooperate with each other to limit the rotation angle range of the reversible cutter head, prevent it from rotating excessively, and thus facilitate the fixing of the reversible cutter head after rotation.

[0015] Preferably, the surface of the reversible cutter head is provided with a number of grooves, which are evenly distributed on both sides of the reversible cutter head.

[0016] The effect achieved by the above-mentioned components is that the several grooves evenly opened on the surface of the reversible cutter head increase the friction between the cutter head and the material, thereby improving the efficiency of shoveling and pushing soil. On the other hand, after the cutter head wears out, the grooves can play a certain buffering role, slowing down the overall wear rate of the cutter head.

[0017] Preferably, a transition plate is fixedly connected to the surface of the frame, and the transition plate is attached to the inner wall of the blade body.

[0018] The effect achieved by the above components is that the transition plate, which is fixedly connected to the frame surface, fits against the inner wall of the blade body. It can fill the gap between the frame and the blade body, making the connection between the two tighter, reducing the wear caused by material entering the gap, and enhancing the stability of the entire structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model, through the design and operation of the aforementioned limiting structure, allows the reversible cutter head to be used on both sides by rotation, extending the service life of the blades, reducing operating costs, improving the operating efficiency and quality of bulldozers, and providing strong support for engineering construction.

[0026] 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.

[0027] Please see Figure 1-4This utility model provides a technical solution: an automatic control blade structure for a bulldozer, including a blade body 1. A limiting structure 2 is provided on the surface of the blade body 1. The limiting structure 2 includes a frame 201. Several bolts 202 are installed on the surface of the frame 201. The frame 201 is mounted on the surface of the blade body 1 using the bolts 202. A rotating shaft 203 is rotatably connected to the surface of the frame 201. A reversible cutter head 204 is fixedly connected to the arc surface of the rotating shaft 203. Circular grooves 205 are provided on both sides of the reversible cutter head 204. Fixing bolts 206 are inserted on both sides of the frame 201. The size of the fixing bolts 206 matches the size of the circular grooves 205. Through the design and operation of the limiting structure 2, the reversible cutter head 204 can be used on both sides by rotation, extending the service life of the blade, reducing operating costs, improving the operating efficiency and quality of the bulldozer, and providing strong support for engineering construction.

[0028] Reference Figure 2 and Figure 3 and 4As shown in this embodiment: extension plates 207 are fixedly connected to both sides of the frame 201. A pin 208 slides through the surface of the extension plate 207, penetrating the fixing bolt 206. The pin 208 is inserted into the fixing bolt 206, thus ensuring that the fixing bolt 206 will not easily dislodge from the circular groove 205, further stabilizing the position of the reversible cutter head 204. A spring 209 is fitted onto the arc surface of the pin 208. Both ends of the spring 209 are fixedly connected to the pin 208 and the extension plate 207 respectively, preventing the pin 208 from dislodging from the fixing bolt 206. An extension arm 210 is fixedly connected to the surface of the frame 201. A baffle 211 is fixedly connected to one end of the extension arm 210 near the reversible cutter head 204. The size of the baffle 211 is larger than the size of the circular groove 205. The extension arm 210 and the baffle 211 fixedly connected to the surface of the frame 201 play an important role in preventing the circular groove 205 from being exposed and entering the soil. A limiting plate 212 is fixedly connected to the arc surface of one end of the rotating shaft 203. Two fixing plates 213 are fixedly connected to the surface of the frame 201. The limiting plate 212 fixedly connected to the arc surface of one end of the rotating shaft 203 and the two fixing plates 213 fixedly connected to the surface of the frame 201 cooperate with each other to limit the rotation angle range of the reversible cutter head 204, prevent it from rotating excessively, and thus facilitate the fixing of the reversible cutter head 204 after rotation. The reversible cutter head 204 has several grooves 214 evenly distributed on both sides. These grooves increase friction between the cutter head and the material, improving shoveling and pushing efficiency. Furthermore, after the cutter head wears down, the grooves 214 act as a buffer, slowing down the overall wear rate. A transition plate 215 is fixedly connected to the surface of the frame 201. This transition plate 215 fits against the inner wall of the blade body 1, filling the gap between the frame 201 and the blade body 1, making the connection tighter, reducing wear caused by material entering the gap, and enhancing the overall structural stability.

[0029] Working Principle: During bulldozer operation, the limiting structure 2 plays a crucial role. When the reversible cutter head 204 needs to be installed, the frame 201 is first installed on the surface of the blade body 1 using bolts 202. After installation, to fix the position of the reversible cutter head 204, fixing bolts 206 are used. The fixing bolts 206 are inserted into the corresponding circular grooves 205 on both sides of the reversible cutter head 204. Since the size of the fixing bolts 206 matches the size of the circular grooves 205, the reversible cutter head 204 is initially fixed, preventing it from rotating randomly during operation. To further enhance the fixing effect, the frame 201... The extension plates 207, fixedly connected on both sides, function as follows: The surface of the extension plates 207 slides through the pin 208, which in turn passes through the fixing bolt 206. A spring 209 is fitted onto the arc surface of the pin 208, with both ends of the spring 209 fixedly connected to the pin 208 and the extension plates 207, respectively. Under the elastic force of the spring 209, the pin 208 always tends to move towards the insertion direction of the fixing bolt 206, thus ensuring that the fixing bolt 206 will not easily dislodge from the groove 205, further stabilizing the position of the reversible cutter head 204. The extension arm 210 and one end of it are fixedly connected to the surface of the frame 201. The baffle 211 also plays an important role in preventing the circular groove 205 from being exposed and entering the soil. The limiting plate 212, which is fixedly connected to the arc surface of one end of the rotating shaft 203, and the two fixing plates 213, which are fixedly connected to the surface of the frame 201, cooperate with each other to limit the rotation angle range of the reversible cutter head 204 and prevent it from rotating excessively. This makes it easier to fix the reversible cutter head 204 after it has rotated. The several grooves 214 evenly opened on the surface of the reversible cutter head 204 increase the friction between the cutter head and the material, improving the efficiency of shoveling and pushing soil. On the other hand, after the cutter head wears down, the grooves 214 can... To provide a certain buffering effect and slow down the overall wear rate of the cutter head, the transition plate 215 fixedly connected to the surface of the frame 201 is attached to the inner wall of the blade body 1. It can fill the gap between the frame 201 and the blade body 1, making the connection between the two tighter, reducing the wear caused by material entering the gap, and enhancing the stability of the entire structure. Through the design and working method of the above-mentioned limiting structure 2, the reversible cutter head 204 can be used on both sides by rotation, which extends the service life of the blade, reduces the operating cost, improves the operating efficiency and quality of the bulldozer, and provides a strong guarantee for engineering construction.
