Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of shot blasting machines, and more specifically, to a tracked shot blasting machine with a gear ring for a transmission system. Background Technology
[0002] In the manufacturing of transmission system gear rings, shot blasting is a key process for improving the surface quality and fatigue strength of the gear rings. Its treatment effect and efficiency directly affect the performance and service life of the gear rings. As the machinery manufacturing industry continues to raise the quality requirements for parts, the limitations of traditional shot blasting equipment are becoming increasingly apparent.
[0003] Currently, most shot blasting equipment used for gear ring treatment in transmission systems faces the challenge of recovering and processing steel balls and debris during operation. During shot blasting, high-speed jets of steel balls impact the gear ring surface, completing rust removal and strengthening processes. However, a large number of steel balls remain mixed with grinding debris. Due to the lack of an effective separation and recovery mechanism, steel balls are difficult to separate precisely from the debris, resulting in low steel ball recovery efficiency. This not only leads to significant steel ball waste and increased production costs but also makes it difficult to directly reuse the recovered steel balls due to the debris residue, requiring additional complex cleaning processes. Simultaneously, the grinding debris is scattered everywhere and cannot be effectively collected and recovered, polluting the working environment and increasing the difficulty of subsequent cleanup. Furthermore, improper handling of this debris can lead to resource waste and environmental pollution. Therefore, developing a tracked shot blasting machine capable of efficiently separating and centrally recovering steel balls and debris is an urgent need to solve current production problems and improve the efficiency and environmental benefits of gear ring shot blasting. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a track-type shot blasting machine for a gear ring in a transmission system, which solves the technical problem in the prior art that after grinding, steel balls and debris are mixed together, making it difficult to recycle the steel balls and also making it difficult to effectively collect and recycle the grinding debris for subsequent processing.
[0005] According to one aspect, at least one embodiment of the present disclosure provides a track-type shot blasting machine for a gear ring in a transmission system, comprising:
[0006] A recycling bin and an outer casing, wherein the outer casing is fixed to the recycling bin;
[0007] The shot blasting machine body, the feeding auger, and the tilting and processing assembly are provided. The shot blasting machine body is installed on the top inside the outer shell. The feeding auger is fixed in the recycling bin and is connected to the shot blasting machine body. The tilting and processing assembly is located in the recycling bin.
[0008] A material sorting component is disposed within the outer casing and the recycling bin;
[0009] The flipping processing assembly includes a feeding pipe located on one side of the recycling bin, a sealing cover rotatably connected to the feeding pipe via a pin, and a flipping frame that is electrically driven to rotate inside the housing, the surface of which has a grid-like structure.
[0010] As a further technical solution, an air inlet is provided on the top of the outer shell, an outer cover is provided on the side surface of the outer shell, a dust collection device connecting pipe is provided on the outer cover, and a barrier mesh is provided at the connection between the outer cover and the outer shell.
[0011] As a further technical solution, the discharge sorting component includes a receiving hopper, which is electrically driven and rotatably connected to the recycling bin, and the surface of the receiving hopper is provided with shot blasting separation holes.
[0012] As a further technical solution, a discharge port is provided at the bottom of the outer shell, and a control cover is rotatably connected to the discharge port via a pin. A cylinder is rotatably connected between the outer surface of the control cover and the side surface of the outer shell via a pin.
[0013] As a further technical solution, a finished product box is provided on one side of the recycling bin, and the bottom surface of the recycling bin is an inclined structural surface.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:
[0018] In this disclosure, the rotating processing component is electrically driven to rotate through a grid-like rotating frame, causing the toothed ring to continuously rotate during the shot blasting process. This ensures that all surfaces of the toothed ring are evenly impacted by steel shot, effectively removing oxide scale and burrs, and improving the comprehensiveness and uniformity of the shot blasting process. At the same time, the air inlet at the top of the housing and the dust collection device connection pipe on the side form an airflow circulation, which can promptly discharge the dust generated during the shot blasting process, preventing dust accumulation from affecting the shot blasting effect and the working environment. This component does not require manual intervention to rotate the toothed ring, achieving efficient shot blasting through automated operation, reducing manual labor intensity, and improving processing efficiency.

[0024] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0030] like Figures 1-3 As shown, a tracked shot blasting machine for a geared ring in a transmission system according to an embodiment of the present disclosure is illustrated, comprising:
[0031] The recycling bin 1 and the outer casing 2 are fixed to the recycling bin 1;
[0032] The shot blasting machine body 3, the feeding auger 4, and the turning and processing component 5 are provided. The shot blasting machine body 3 is installed on the top inside the outer shell 2. The feeding auger 4 is fixed in the recycling box 1 and is connected to the shot blasting machine body 3. The turning and processing component 5 is set in the recycling box 1.
[0033] A material sorting component is disposed in the outer shell 2 and the recycling bin 1;
[0034] The flipping processing component 5 includes a feeding pipe 5-1, which is located on one side of the recycling bin 1. A sealing cover 5-2 is rotatably connected to the feeding pipe 5-1 via a pin. A flipping rack 5-3 driven by electricity is installed inside the outer shell 2. The surface of the flipping rack 5-3 has a grid-like structure. An air inlet 5-4 is opened on the top of the outer shell 2. An outer cover 5-5 is provided on the side surface of the outer shell 2. A dust collection equipment connecting pipe 5-7 is provided on the outer cover 5-5. A barrier mesh 5-6 is provided at the connection between the outer cover 5-5 and the outer shell 2.
[0035] In some examples, to achieve omnidirectional shot blasting and dust removal of the gear rings, a flipping processing component 5 is designed. This component includes a feed pipe 5-1 connected to a recovery box 1 on the side, and a sealing cover 5-2 connected by a pin can be opened manually or pneumatically to facilitate the insertion of the gear rings. The flipping rack 5-3 inside the housing 2 is driven to rotate by a motor. Its grid-like surface allows shot blasting to pass through while simultaneously lifting the gear rings and causing them to tumble. For example, the gear rings continuously flip on the flipping rack 5-3 as it rotates, and the steel shot ejected from the shot blasting machine body 3 impacts the surface of the gear rings from different angles, removing oxide scale and burrs.
[0036] The air inlet 5-4 at the top of the outer casing 2 and the side dust collection device connecting pipe 5-7 form an airflow circulation: the air inlet 5-4 introduces outside air, mixes it with the dust generated during the shot blasting process, filters out large particles of impurities through the barrier mesh 5-6, and is then extracted by the dust collection device to prevent dust accumulation. This ensures that the shot blasting process evenly covers the inner and outer surfaces of the toothed ring.
[0037] like Figures 1-3 As shown, this embodiment proposes a discharge sorting component including a receiving hopper 6-1. The receiving hopper 6-1 is rotatably connected to the recycling box 1 by electric drive. The surface of the receiving hopper 6-1 is provided with shot blasting separation holes 6-2. The bottom of the outer shell 2 is provided with a discharge port 6-3. A control cover 6-4 is rotatably connected to the discharge port 6-3 by a pin. A cylinder 6-5 is rotatably connected between the outer surface of the control cover 6-4 and the side surface of the outer shell 2 by a pin.
[0038] In some examples, to achieve automatic separation of the gear ring and shot blasting, a discharge sorting component is designed. This component includes a receiving hopper 6-1 fixed inside the recovery bin 1, driven by a motor. Shot blasting separation holes 6-2 on the surface allow shot to pass through, while the gear ring is intercepted inside the hopper. As the receiving hopper 6-1 rotates, the shot falls through the holes into the bottom of the recovery bin 1 and is then re-transported to the shot blasting machine body 3 by the feeding auger 4 for reuse. Meanwhile, the gear ring rotates with the receiving hopper 6-1 to the discharge port 6-3 at the bottom of the outer casing 2.
[0039] The control cover 6-4 of the discharge port 6-3 is connected to the cylinder 6-5 via a pin. The extension and retraction of the piston rod of the cylinder 6-5 drives the control cover 6-4 to open and close. For example, when the gear ring reaches the position of the discharge port 6-3, the cylinder 6-5 actuates to open the control cover 6-4, and the gear ring is discharged under gravity. Subsequently, the control cover 6-4 closes to prevent shot blasting leakage. This rotary screening pneumatic unloading design achieves a separation efficiency of over 95% between the gear ring and the shot blasting material. Furthermore, the discharge process can be automatically controlled by a PLC program, reducing manual intervention and making it suitable for continuous shot blasting of gear rings in mass production scenarios.
[0040] For example, such as Figure 3 As shown, a finished product box 7 is provided on one side of the recycling bin 1, and the bottom surface of the recycling bin 1 is an inclined structural surface.
[0041] In some examples, the finished product box 7 located on one side of the recycling bin 1, together with its inclined inner bottom surface, constitutes an automatic discharge system. The inner bottom surface of the recycling bin 1 is designed at an inclined angle. After the gear rings fall through the discharge port 6-3, they slide along the inclined surface towards the finished product box 7 under the influence of gravity. This design eliminates the need for an additional power unit, enabling automatic conveying of the gear rings, reducing manual handling and labor intensity. For example, after shot blasting, the gear rings are discharged through the discharge port 6-3 and, guided by the inclined bottom surface, can quickly and smoothly slide into the finished product box 7 for centralized collection, preventing accumulation in the recycling bin 1 and affecting subsequent processing, thus effectively improving overall production efficiency.
[0042] For example, such as Figure 3 As shown, the bottom of the outer shell 2 has a semi-circular arc transition structure.
[0043] In some examples, the semi-circular arc-shaped transition structure at the bottom of the outer casing 2 optimizes the shot blasting recovery path. The arc design reduces dead angles for shot accumulation at the bottom of the outer casing 2, allowing the steel shot to slide more smoothly into the recovery box 1 under gravity. Compared to a right-angle structure, the arc transition increases the downward speed of the shot, reducing the risk of equipment wear due to steel shot residue. For example, during shot blasting, after the steel shot collides with the toothed ring, it bounces back to the bottom of the outer casing 2. The arc structure guides it to roll quickly towards the recovery area. Combined with the inclined bottom surface of the recovery box 1, this ensures efficient steel shot recovery and maintains the stability of the shot blasting circulation system.
[0044] For example, as shown in the figure, the receiving hopper 6-1 has a single-sided opening structure.
[0045] In some examples, the single-sided opening structure of the receiving hopper 6-1 enables directional discharge control. The opening direction corresponds to the discharge port 6-3 at the bottom of the outer casing 2. When the receiving hopper 6-1 rotates to a specific position, the toothed ring can be accurately discharged. This design avoids the problem of toothed ring scattering that may occur with traditional fully open receiving hoppers 6-1, ensuring accurate discharge position. For example, during one rotation of the receiving hopper 6-1, the toothed ring is released only when the opening is aligned with the discharge port 6-3. Combined with the opening and closing action of the control cover 6-4, precise and orderly unloading is achieved, preventing equipment jamming or toothed ring damage caused by chaotic discharge, and improving the reliability of the discharge process.
[0046] For example, such as Figure 1 As shown, the lower end of the feeding auger 4 is located at the deepest point inside the recycling bin 1, and the feeding auger 4 is fixed at an inclined angle.
[0047] In some examples, the feed auger 4 is tilted and fixed with its lower end located at the deepest part of the recovery bin 1, ensuring efficient shot blasting circulation. The auger tilt angle is typically set to 30°-45°, which utilizes gravity to assist in conveying while ensuring that the spiral blades effectively grasp the steel shot. Its lower end extends into the recessed area at the bottom of the recovery bin 1, allowing all scattered steel shot to be collected.
[0048] In actual use: Open the sealing cover 5-2 on the feed pipe 5-1, put the toothed ring into the recovery box 1 through the feed pipe 5-1, close the sealing cover 5-2, start the electric drive device of the tilting frame 5-3 inside the outer shell 2, the grid-like structure on the surface of the tilting frame 5-3 lifts the toothed ring and drives it to rotate, at the same time the shot blasting machine body 3 starts to work, spraying steel shot onto the toothed ring for shot blasting. During the shot blasting process, air is introduced through the air inlet 5-4 at the top of the outer shell 2, mixed with the dust generated by shot blasting, and after being filtered by the barrier mesh 5-6 at the connection between the outer cover 5-5 and the outer shell 2, large particles of impurities are extracted by the dust collection equipment connected by the dust collection equipment connecting pipe 5-7 to avoid dust accumulation. After the shot blasting is completed, the air... The cylinder 6-5 drives the control cover 6-4 to rotate around the pin, opening the discharge port 6-3 at the bottom of the outer shell 2. At the same time, the receiving hopper 6-1 rotates by electric drive. The shot separation hole 6-2 on the surface of the receiving hopper 6-1 allows the steel shot to pass through and fall into the recycling box 1. The gear ring is intercepted in the receiving hopper 6-1. When the receiving hopper 6-1 rotates to the position of the discharge port 6-3, it is discharged into the finished product box 7 on one side of the recycling box 1 under the action of gravity. The bottom surface of the recycling box 1 is an inclined structure surface, which can guide the gear ring to slide smoothly into the finished product box 7. The steel shot that falls into the recycling box 1 is transported back to the shot blasting machine body 3 by the feeding auger 4 located at the deepest part of the recycling box 1 and at a fixed inclined angle, realizing the recycling of steel shot.
