Description

Technical Field

[0001] The utility model relates to the technical field of mine motors, and particularly relates to a mine motor with an automatic lubrication function. Background Technique

[0002] After a mine motor is used for a long time, the rotor will be damaged due to friction. In order to extend the service life of the rotor, a lubricating device needs to be installed to lubricate the outer surface of the rotor, reduce friction, make the rotor rotate more smoothly, and play a protective role at the same time.

[0003] After retrieval, a Chinese patent discloses a motor rotor with an automatic lubrication function (publication number: CN213990315U). In this patented technology, by setting up a lubricating device, when the rotor rotates, the balls between the fixed ring and the gear will rotate. There is a certain interval between each ball. When the balls rotate, they will touch the trigger rod. The connecting rod on the trigger rod makes the sliding plate slide to the right, so that it can no longer block the outflow of the lubricating oil. The lubricating oil seeps out of the oil outlet hole every once in a while and drips onto the surface of the gear to lubricate the gear, reduce the friction force, and extend the service life of the rotor, achieving the effect of ensuring the durability of the rotor. However, it does not have the effect of recycling and reuse, and the consumption of lubricating oil is relatively large. Therefore, those skilled in the art provide a mine motor with an automatic lubrication function to solve the problems raised in the above background technique. Summary of the Utility Model

Among them, the lubricating structure includes a connecting ring fixedly connected to the inner side of the protective shell. A cavity is opened inside the connecting ring. The inner wall of the cavity is fixedly connected with two symmetrically distributed partitions. A storage cavity is formed between the top of the two partitions and the cavity, and a waste liquid cavity is formed between the bottom of the partitions and the cavity. A liquid adding pipe communicating with the waste liquid cavity is arranged on the surface of the connecting ring, and the other end of the liquid adding pipe penetrates through the protective shell.

[0006] Preferably, evenly distributed balls are rotatably connected inside the storage cavity. One end of each ball penetrates through the connecting ring and contacts the surface of the rotor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Specifically, as Figures 1-4 shown, a mine motor with an automatic lubrication function includes: a motor housing 1 and a rotor 101, and a protective housing 102 is fixedly connected to the surface of the motor housing 1; a lubrication structure 2 is arranged inside the protective housing 102, and the rotor 101 penetrates through the lubrication structure 2; wherein, the lubrication structure 2 includes a connecting ring 201 fixedly connected to the inner side of the protective housing 102, a cavity 203 is formed inside the connecting ring 201, two partitions 205 are fixedly connected to the inner wall of the cavity 203 and are symmetrically distributed, a storage cavity is formed between the tops of the two partitions 205 and the cavity 203, and a waste liquid cavity is formed between the bottoms of the partitions 205 and the cavity 203. A liquid adding pipe 202 communicating with the waste liquid cavity is arranged on the surface of the connecting ring 201, and the other end of the liquid adding pipe 202 penetrates through the protective housing 102.

[0020] As Figure 1 , Figure 2 and Figure 3 shown, evenly distributed balls 204 are rotatably connected inside the storage cavity. One end of the ball 204 penetrates through the connecting ring 201 and contacts the surface of the rotor 101. A groove is formed inside the inner side of the connecting ring 201, and through holes 208 evenly distributed and communicating with the waste liquid cavity are formed in the inner wall of the groove. An infiltration block 207 is fixedly connected to the top of the partition 205, and an oil absorption cotton strip 206 is arranged inside the waste liquid cavity. The two ends of the oil absorption cotton strip 206 are respectively fixedly connected to the bottoms of the two infiltration blocks 207.

[0021] Lubricating oil is added to the inside of the storage cavity through the liquid adding pipe 202. During the rotation of the rotor 101, the balls 204 can be driven to rotate. Since part of the balls 204 is located inside the storage cavity and adheres to the lubricating oil, the lubricating oil can be driven to contact the rotor 101 during the rotation process to achieve the effect of self-lubrication. As the rotor 101 rotates, the excess lubricating oil can drip into the groove and be introduced into the waste liquid cavity through the through holes 208 for storage and reuse, reducing the loss of lubricating oil;

[0022] The lubricating oil that enters the interior of the waste liquid cavity can also collect the dust and debris adhering to the surface of the rotor 101 during the dripping process and collect them into the waste liquid cavity together, reducing the dust and debris in the working environment of the mining motor from entering the motor housing 1 and affecting the use of the motor. The oil-absorbing cotton strip 206 and the wetting block 207 can absorb the oil so that the dust and debris cannot be introduced into the interior of the storage cavity through the oil-absorbing cotton strip 206 and the wetting block 207, effectively reducing the loss of lubricating oil and improving the service life.

[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a drain pipe 209 is provided at the bottom of the protective shell 102. The upper end of the drain pipe 209 is communicated with the waste liquid cavity. A plugging block 214 is provided at the bottom of the drain pipe 209. The top of the plugging block 214 penetrates through the drain pipe 209 and is threadedly connected to the inner wall of the drain pipe 209. A sealing ring 213 is fixedly connected to the inner wall of the drain pipe 209. A connecting rod 210 is fixedly connected to the top of the plugging block 214. The upper end of the connecting rod 210 penetrates through the sealing ring 213 and is fixedly connected to a mounting block. A through groove 212 is provided on the surface of the connecting rod 210. A spring 211 is fixedly connected between the bottom of the mounting block and the top of the sealing ring 213.

[0024] By rotating the plugging block 214 to drive the connecting rod 210 to move downward, the through groove 212 can be driven to pass through the sealing ring 213 during this process, so that the waste oil and the collected debris and dust in the waste liquid cavity can be discharged through the drain pipe 209, facilitating the re-addition of lubricating oil. The spring 211 is provided to assist the reset of the plugging block 214.

[0025] When the present utility model is in use, lubricating oil is added to the interior of the storage cavity through the liquid adding pipe 202. During the rotation of the rotor 101, the ball 204 can be driven to rotate. Since a part of the ball 204 is located in the storage cavity and adheres to the lubricating oil, the lubricating oil can be driven to contact the rotor 101 during the rotation process to achieve the effect of self-lubrication. As the rotor 101 rotates, the excess lubricating oil can drip into the interior of the groove and be introduced into the waste liquid cavity through the through hole 208 for storage and reuse, reducing the loss of lubricating oil. And under the combined action of the waste liquid cavity, the oil-absorbing cotton strip 206 and the wetting block 207, the waste oil is filtered and reused, improving the service life and reducing the replacement times.

[0026] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
