Description

Technical Field

[0001] This utility model relates to the field of automotive disassembly technology, specifically to an automotive disassembly puncture and oil draining machine. Background Technology

[0002] As a key link in resource recycling and environmental protection, automobile dismantling is closely related to the standardization of automobile dismantling processes and the improvement of environmental protection requirements. During this period, automobile dismantling puncture and oil draining machines are the core equipment in the pre-treatment of scrapped automobiles.

[0003] Traditional oil draining machines typically involve puncturing the bottom of the fuel tank to drain the oil. However, this method is inefficient and significantly impacts overall efficiency. Therefore, a faster oil draining machine for automotive disassembly was designed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an oil draining machine for disassembling automobiles by punching holes, so as to solve the technical problem that the oil draining speed of traditional oil draining machines is relatively slow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car disassembly puncture and oil draining machine, comprising a main frame, a pneumatic device connected to one side of the main frame with damping rotatability, and a puncture rod with a pointed tip connected to the output end of the pneumatic device, a rotating cylinder rotatably sleeved on the puncture rod, and a slider slidably connected to the puncture rod at the end of the rotating cylinder facing the pointed tip, a plurality of evenly arranged beveled blades slidingly passing through the rotating cylinder, the beveled blades being arranged at an angle, the top of the beveled blades being chamfered, a locking block fixed to the outside of the puncture rod at the rotating cylinder, a limiting block cooperating with the locking block connected to the inward-facing side of each beveled blade, and a spring piece slidably connected between each beveled blade and the puncture rod.

[0006] By adopting the above technical solution, when oil draining operations are required, the pneumatic device is rotated so that the puncture rod faces upwards. The puncture rod is placed below the oil tank, and the pneumatic device is activated. The puncture rod moves upwards and inserts into the oil tank. During this upward movement, the tip of the beveled blade contacts the edge of the oil tank hole, thus squeezing the beveled blade into the rotating drum. After the upward puncture is completed, the pneumatic device drives the puncture rod to descend. Before this, the beveled blade located in the oil tank is ejected by the spring. At this time, as the puncture rod descends, the bottom edge of the beveled blade contacts the oil tank, thus driving the rotating drum to move upwards along the slider. This causes the limiting block on the beveled blade to contact the locking block, thereby limiting the beveled blade and preventing its retraction. At this time, as the puncture rod descends, the beveled blade slowly cuts open the edge of the oil drum puncture hole, and... Furthermore, due to the inclined arrangement of the beveled blades, the beveled blades, along with the rotating drum, slowly rotate as it descends, thus creating an inclined notch at the edge of the puncture hole in the oil drum. At this time, the oil in the tank flows out along the inclined notch, forming a rotating water column, which in turn causes a vortex to form inside the tank. During this process, for the oil particles near the bottom of the tank with puncture holes, their radius of rotation is relatively small. However, since the entire oil body is connected, when the oil particles in the upper layer of the oil body move outward due to centrifugal force during rotation, it will cause the oil particles in the lower layer to also move. This tendency of movement makes it easier for the oil particles to move downward because the centrifugal force overcomes the internal friction and other resistance between the oil particles to a certain extent, which increases the speed at which the oil flows downward, ultimately increasing the oil discharge speed from the tank.

[0007] The present invention is further configured such that a receiving cylinder is sleeved on the stamping rod, and a spring is connected between the receiving cylinder and the pneumatic device.

[0008] By adopting the above technical solution, the receiving cylinder is pushed upward under the action of the spring, ensuring a tight fit with the puncture opening of the oil tank, effectively preventing oil splashing and improving the cleanliness and safety of the oil discharge process.

[0009] The present invention is further configured such that an oil storage tank is installed inside the main frame, and a sealing slide plate is slidably connected inside the oil storage tank. The bottom end of the sealing slide plate is under negative pressure with the oil storage tank. A switch valve is installed on the main frame, and the two ends of the switch valve are respectively connected to the oil storage tank and the receiving cylinder.

[0010] By adopting the above technical solution, the switch valve is opened, and the oil collected by the receiving cylinder is smoothly sucked into the oil storage tank by the principle of negative pressure as the sealing slide plate descends. The switch valve can also ensure that the oil will not flow out after collection is completed.

[0011] The present invention is further provided that a sealing strip is installed at the top of the receiving tube.

[0012] By adopting the above technical solution, the sealing strip can enhance the sealing between the receiving cylinder and the oil tank drain port, so that the receiving cylinder is in a low-pressure state, and the oil can be discharged quickly under the action of atmospheric pressure.

[0013] The present invention is further configured such that a stop block that cooperates with the main frame is fixed on the pneumatic device.

[0014] By adopting the above technical solution, the stop can limit the movement range of the pneumatic device, prevent the pneumatic device from swinging or moving excessively during operation, and ensure the stability and safety of the entire device.

[0015] The present invention is further configured such that a roller is installed at the bottom end of the main frame and a push handle is installed on one side of the main frame.

[0016] By adopting the above technical solutions, the rollers allow the equipment to be easily moved around the car dismantling site and quickly moved to the side of the car that needs to be drained, improving work efficiency. The push handle makes it easy for operators to push the equipment, reducing the labor intensity of manual handling.

[0017] The present invention is further configured such that a support frame is installed on the side of the main frame away from the pneumatic device.

[0018] By adopting the above technical solution, when the oil discharge machine is working, the main frame is pushed so that the rollers are lifted off the ground and the support frame is in contact with the ground, preventing the rollers from moving the equipment during operation. The support frame can provide additional support, making the equipment more stable.

[0019] The present invention is further provided that the pneumatic device is equipped with a lifting handle.

[0020] By adopting the above technical solution, the lifting handle makes it easier for operators to lift the pneumatic device. When it is necessary to adjust the position of the pneumatic device or perform other related operations, the pneumatic device can be controlled more conveniently, thus improving the ease of operation.

[0021] The present invention is further provided that the oil storage tank is provided with an observation window that cooperates with the sealing slide plate.

[0022] By adopting the above technical solution, the observation window allows for a direct view of the oil collection status in the oil storage tank, enabling operators to promptly understand the oil release progress and facilitate timely handling of the collected oil, thereby improving work efficiency and ease of use of the equipment.

[0023] In summary, the present invention has the following main advantages:

[0024] This invention uses a pneumatic device to drive the piercing rod and the beveled blade on the rotating drum. Compared with the traditional piercing method for oil discharge, it can quickly penetrate the oil tank and cut an inclined notch, allowing the oil to quickly gush out from the discharge port under the action of centrifugal force and fluid mechanics, thus significantly improving the oil discharge efficiency. At the same time, the receiving cylinder and spring work together to collect the oil and prevent splashing. The negative pressure design of the oil storage tank and the setting of the switch valve further accelerate the collection of oil. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] A car disassembly puncture and drain oil machine, such as Figure 1-6As shown, the device includes a main frame 1, with rollers 18 installed at the bottom of the main frame 1 and a push handle 17 installed on one side of the main frame 1. The rollers 18 allow the device to be easily moved in the car dismantling site and can be quickly moved to the side of the car that needs to be drained, thus improving work efficiency. The push handle 17 makes it easy for operators to push the device, reducing the labor intensity of manual handling.

[0035] After that, as Figure 1-2 As shown, a support frame 19 is installed on the side of the main frame 1 away from the pneumatic device 3. When the oil discharge machine is working, the main frame 1 is pushed, causing the roller 18 to leave the ground and the support frame 19 to contact the ground, preventing the roller 18 from moving the equipment during operation. The support frame 19 can provide additional support, making the equipment more stable.

[0036] Subsequently, as Figure 1-6As shown, a pneumatic device 3 is rotatably connected to one side of the main frame 1, and the output end of the pneumatic device 3 is connected to a stinging rod 4 with a pointed tip. A rotating cylinder 9 is rotatably mounted on the stinging rod 4, and a slider 10 that is slidably connected to the stinging rod 4 is connected to the end of the rotating cylinder 9 facing the pointed tip. Several evenly arranged beveled blades 6 slide through the rotating cylinder 9, and the beveled blades 6 are arranged at an angle. The tips of the beveled blades 6 are chamfered. A locking block 5 is fixed to the outside of the stinging rod 4 at the rotating cylinder 9. Each beveled blade 6 has a locking block 5 connected to its inward-facing side. The limiting block 7 and each beveled blade 6 are slidably connected to the puncture rod 4 by a spring piece 8. When oil draining is required, the pneumatic device 3 is rotated so that the puncture rod 4 faces upward and is placed below the oil tank. The pneumatic device 3 is then activated, and the puncture rod 4 moves upward and inserts into the oil tank. During this process, the tip of the beveled blade 6 contacts the edge of the oil tank hole, thus squeezing the beveled blade 6 into the rotating cylinder 9. After the puncture is completed, the pneumatic device 3 drives the puncture rod 4 to descend. Before this, the beveled blade 6 located in the oil tank is ejected by the spring piece 8. At this time, along with the puncture rod... As the puncture rod 4 descends, the bottom edge of the beveled blade 6 contacts the oil tank, causing the rotating drum 9 to move upward along the slider 10. This causes the limiting block 7 on the beveled blade 6 to contact the locking block 5, thus limiting the beveled blade 6 and preventing it from retracting. At this time, as the puncture rod 4 descends, the beveled blade 6 slowly cuts a notch at the edge of the puncture hole in the oil drum. Due to the inclined arrangement of the beveled blades 6, the beveled blades 6, along with the rotating drum 9, slowly rotate as it descends, creating an inclined notch at the edge of the puncture hole in the oil drum. At this point, the oil in the tank flows out along the inclined notch, forming... A rotating column of water creates a vortex inside the fuel tank. During this process, the oil particles near the bottom of the tank with punctures have relatively small radii of rotation. However, since the entire oil body is interconnected, when the oil particles in the upper layer are subjected to centrifugal force and move outward during rotation, they will also cause the lower layer of oil particles to move. This tendency makes it easier for the oil particles to move downward because the centrifugal force overcomes the internal friction and other resistance between the oil particles to a certain extent, thus accelerating the downward flow of the oil and ultimately speeding up the rate at which the fuel tank discharges oil.

[0037] At the same time, such as Figure 1-4 As shown, a receiving cylinder 12 is sleeved on the puncture rod 4, and a spring 14 is connected between the receiving cylinder 12 and the pneumatic device 3. Under the action of the spring 14, the receiving cylinder 12 is pushed upward to ensure a tight fit with the puncture opening of the oil tank, effectively preventing oil from splashing out and improving the cleanliness and safety of the oil discharge process.

[0038] Subsequently, as Figure 1-4As shown, an oil storage tank 2 is installed inside the main frame 1, and a sealing slide plate 21 is slidably connected inside the oil storage tank 2. There is a negative pressure between the bottom end of the sealing slide plate 21 and the oil storage tank 2. A switch valve 11 is installed on the main frame 1, and the two ends of the switch valve 11 are connected to the oil storage tank 2 and the receiving cylinder 12, respectively. When the switch valve 11 is opened, the oil collected by the receiving cylinder 12 is smoothly sucked into the oil storage tank 2 by utilizing the principle of negative pressure as the sealing slide plate 21 descends. The switch valve 11 can ensure that the oil will not flow out after collection.

[0039] Furthermore, such as Figure 1-6 As shown, a sealing strip 13 is installed at the top of the receiving cylinder 12. The sealing strip 13 can enhance the sealing between the receiving cylinder 12 and the oil tank drain port, so that the receiving cylinder 12 is in a low-pressure state, and the oil can be discharged quickly under the action of atmospheric pressure.

[0040] In addition, such as Figure 1-3 As shown, a stop block 15 is fixed on the pneumatic device 3 to cooperate with the main frame 1. The stop block 15 can limit the movement range of the pneumatic device 3, preventing the pneumatic device 3 from swinging or moving excessively during operation, and ensuring the stability and safety of the entire device.

[0041] Among them, such as Figure 1-3 As shown, a lifting handle 16 is installed on the pneumatic device 3. The lifting handle 16 makes it convenient for the operator to lift the pneumatic device 3. When it is necessary to adjust the position of the pneumatic device 3 or perform other related operations, it is easier to control the pneumatic device 3 and improve the convenience of operation.

[0042] In addition, such as Figure 1-3 As shown, the oil storage tank 2 is equipped with an observation window 20 that cooperates with the sealing slide plate 21. The observation window 20 allows for a direct observation of the oil collection status in the oil storage tank 2, making it convenient for operators to understand the oil release progress in a timely manner, facilitating the timely handling of the collected oil, and improving work efficiency and ease of use of the equipment.
