[0001] The present application relates to the technical field of gear boxes, and in particular to a gear box ventilation device and a gear box. Background Art

[0002] Gearboxes have a wide range of applications. The main functions of gearboxes include acceleration and deceleration, changing transmission direction, changing torque, clutch function and power distribution.

[0016] The beneficial effects of this application are as follows: 1. When the present application is in use, the fan blades are driven to rotate to draw outside air into the installation shell through the air intake pipe. During the process, dust in the air is blocked by the filter plate to reduce the possibility of dust entering the installation shell. In the process, the fan blades are driven to drive the driving rod to drive the impact rod, and the impact rod is used to impact the filter plate, so that vibration is generated on the filter plate, which reduces the possibility of dust adhering to the filter plate. The reciprocating sliding of the impact rod drives the sliding plate to resist or release the resistance to the scraping rod, and the scraping rod scrapes the surface of the filter plate, which further reduces the possibility of dust adhering to the filter plate and clogging the filter plate.

[0017] 2. The positions of the inclined plates in the intake pipe of the present application are offset from each other, so that the inclined plates will not block the airflow entering the intake pipe. However, when the airflow enters the intake pipe, the dust carried in the airflow will contact and collide with the inclined plates, so that part of the dust in the airflow will be blocked by the inclined plates. When viewed from the direction of the intake pipe opening to the inside, the sum of the areas between the inclined plates is consistent with the diameter of the intake pipe, thereby increasing the dust shielding effect of the inclined plates. The inclined plates are inclined toward the outside of the intake pipe, so that the dust on the inclined plates will slide away from the filter plate due to gravity, thereby reducing the dust in the airflow that contacts the filter plate, thereby reducing the possibility of the filter plate being blocked by dust.

[0018] 3. The ring plate and the friction rod of the present application are both made of plastic. When the two rub against each other, static electricity is generated on the two, so that when the air passes through the ring plate, the dust inside the air flow is adsorbed by static electricity, further reducing the possibility of dust adhering to the filter plate, thereby reducing the possibility of dust clogging the filter plate. In the process of contact and friction between the friction rod and the ring plate, the dust inside the ring plate is scraped and the dust on the ring plate is scraped and gathered. When the dust is adsorbed and gathered into a group through static electricity, and the gravity of the dust group is greater than the static electricity adsorption force, it will slide down along the inclined surface of the inner wall of the ring plate. The air intake pipe is provided with a channel on the side of the ring plate close to the air intake pipe outlet. When the dust slides downward, it slides to the outside of the air intake pipe through the channel, reducing the possibility of dust accumulation in the air intake pipe.

[0019] 4. When the present application is in use, the vertical rod reciprocates in the air intake pipe to drive the spring telescopic rod and the sliding block to reciprocate on the inclined plate, and then the dust on the inclined plate is scraped by the sliding block. During the process, when the sliding block drives the sponge block to move to the highest point, the lubricating oil in the oil storage chamber is discharged, so that the lubricating oil can adhere to the sponge block. When in use, the viscosity of the lubricating oil increases the cleaning effect of the sponge block on the dust, and in the process of the sponge block moving on the inclined plate, an oil film of lubricating oil is also attached to the inclined plate, so that the inclined plate can better absorb dust, thereby reducing the possibility of dust contacting the filter plate, and reducing the possibility of the filter plate being blocked.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] Embodiment 1 like Figure 1 - Fig.12 As shown, the gearbox ventilation device proposed in the first embodiment of the present application includes: The mounting shell 1 is provided with an air inlet 101 and an air outlet 102. An air inlet pipe 103 is installed on the mounting shell 1. The air inlet pipe 103 is offset from the air inlet 101. The air inlet pipe 103 allows external airflow to enter the mounting shell 1. Both the air inlet 101 and the air outlet 102 are provided with a one-way valve. The air inlet 101 allows the airflow outside the mounting shell 1 to enter the mounting shell 1 in only one direction. A pipe body is installed at the air inlet 101. One end of the pipe body is connected to the air inlet 101, and the other end is connected to the air inlet 101. One end penetrates the mounting shell 1 and is located outside. When the gear box ventilation device is connected to the gear box, the pipe body at the air inlet 101 is connected to the inside of the gear box, and the gas that is about to enter the mounting shell 1 is discharged to the outside of the mounting shell 1 through the guidance of the pipe body. The air outlet 102 is also connected to the inside of the gear box so that the airflow inside the mounting shell 1 is unidirectionally discharged to the inside of the gear box, so that the air in the gear box can circulate, so that the gear box ventilation device can keep the pressure inside and outside the gear box balanced; The filter plate 2 is installed in the air inlet pipe 103. A driving blade 201 is rotatably installed in the air inlet pipe 103. A motor is also installed in the air inlet pipe 103. The output shaft of the motor is connected to the driving blade 201. The driving blade 201 is driven by the rotation of the motor output shaft, so that the driving blade 201 can draw the external air into the installation shell 1. A driving rod 202 is eccentrically hinged on the rotating shaft of the driving blade 201, and a striking rod 203 hinged to the driving rod 202 is slidably installed in the air intake pipe 103. The striking rod 203 is located on the side of the filter plate 2 away from the opening of the air intake pipe 103. The striking rod 203 is used to strike the filter plate 2. A groove is opened in the air intake pipe 103, and a block slidably inserted in the groove is installed on the striking rod 203. The side wall of the block is restricted by the inner wall of the groove, so that the striking rod 203 can only slide in the air intake pipe 103 in a straight line. When in use, when the driving blade 201 rotates, the driving rod 202 is driven to perform a circular motion in the air inlet pipe 103 around the axis direction of the driving blade 201. When the driving rod 202 rotates along with the rotating shaft of the driving blade 201, the impact rod 203 is pushed or pulled to slide back and forth in the air inlet pipe 103. When the impact rod 203 approaches the filter plate 2, it impacts the filter plate 2, causing vibration on the filter plate 2, and then the floating dust on the filter plate 2 is shaken off by the vibration, reducing the possibility of the filter plate 2 being blocked by dust. by Figure 1 From the main perspective, the air inlet pipe 103 is provided with a passage in the vertical downward direction of the filter plate 2, and the passage is connected to the outside. When dust is shaken off, it falls to the outside of the air inlet pipe 103 through the passage, thereby reducing the possibility of dust accumulation in the air inlet pipe 103; A resistance block 204 is installed on the impact rod 203, and a sliding plate 206 is slidably installed on the air inlet pipe 103 through a connecting spring 205. A resistance oblique rod 207 for resisting the resistance block 204 is installed on the sliding plate 206. The sliding plate 206 is L-shaped, and its free end slides through the air inlet pipe 103 and is located on the side of the filter plate 2 close to the outlet of the air inlet pipe 103. The resistance block 204 is provided with an inclined surface, and the resistance oblique rod 207 is also provided with an inclined surface parallel to the inclined surface on the resistance block 204. One end of the resistance oblique rod 207 penetrates the air inlet pipe 103 and is located outside. One end of the sliding plate 206 is located outside the air inlet pipe 103 and is connected to the resistance oblique rod 207, and the other end slides through the air inlet pipe 103 and is located inside it. One end of the sliding plate 206 located in the air inlet pipe 103 contacts the surface of the filter plate 2. When in use, when the impact rod 203 approaches the filter plate 2, it drives the resistance block 204 to resist the resistance inclined rod 207, so that it slides in the direction away from the air inlet pipe 103 through the inclined surface, and then pushes the sliding plate 206. When the impact rod 203 is away from the filter plate 2, it drives the resistance block 204 to release the resistance to the resistance inclined rod 207, so that the connecting spring 205 pulls the sliding plate 206 to reset, so that the sliding plate 206 slides on the surface of the filter plate 2, so that when the impact rod 203 hits the filter plate 2, it also drives the sliding plate 206 to scrape the surface of the filter plate 2, further reducing the possibility of dust adhering to the filter plate 2. The scraper rod 3 is rotatably mounted on the filter plate 2 through a torsion spring 301. The scraper rod 3 is in contact with the surface of the filter plate 2 on one side facing the outlet of the air inlet pipe 103. There are multiple scraper rods 3 and they are an even number. The adjacent scraper rods 3 are connected by connecting gears 302 on the rotating shafts. When the sliding plate 206 contacts the scraper rod 3, the scraper rod 3 moves in an arc on the surface of the filter plate 2. A plate body is installed on one end of the sliding plate 206 located inside the air inlet pipe 103. The plate body is used to extend the width of the sliding plate 206, which increases the contact between the sliding plate 206 and the dust on the filter plate 2. At the same time, the sliding plate 206 can contact the free end of the scraper rod 3 through the block. When the sliding plate 206 slides toward the air inlet pipe 103, the scraper rod 3 is pressed by the block thereon, so that the scraper rod 3 rotates, and the adjacent scraper rod 3 is driven to rotate together through the connecting gear 302, so that the scraper rod 3 also scrapes the surface of the filter plate 2. The contact area between the device and the dust on the filter plate 2 is increased through the scraper rod 3, thereby further increasing the cleaning effect of the device on the filter plate 2 and reducing the possibility of the device being blocked; Compared with the prior art, when in use, the outside air is drawn into the mounting shell 1 through the air inlet pipe 103 by driving the rotation of the fan blades 201. During the process, the dust in the air is blocked by the filter plate 2 to reduce the possibility of dust entering the mounting shell 1. In the process, the fan blades 201 are driven to drive the driving rod 202 to drive the impact rod 203, and the impact rod 203 is used to impact the filter plate 2, so that vibration is generated on the filter plate 2, reducing the possibility of dust adhering to the filter plate 2, and the reciprocating sliding of the impact rod 203 drives the sliding plate 206 to resist or release the resistance to the scraping rod 3, and the scraping rod 3 scrapes the surface of the filter plate 2, further reducing the possibility of dust adhering to the filter plate 2 and clogging the filter plate 2.

[0023] Embodiment 2 like Fig.12As shown, the second embodiment is based on the first embodiment to further disclose the intake pipe 103 and the mounting shell 1. In the second embodiment, an inclined plate 4 is installed on the intake pipe 103, and the inclined plate 4 is installed obliquely in the intake pipe 103. The lowest point of the inclined plate 4 is closer to the opening of the intake pipe 103 than the highest point. There are at least two inclined plates 4, and there are channels for airflow between the inclined plates 4. The sum of the projected areas of the inclined plates 4 on the filter plate 2 blocks the filter plate 2. The positions of the inclined plates 4 in the intake pipe 103 are mutually staggered, so that the inclined plates 4 will not block the airflow entering the intake pipe 103. However, when the airflow enters the air intake pipe 103, the dust carried in the airflow will contact and collide with the inclined plate 4, so that part of the dust in the airflow will be blocked by the inclined plate 4. When projected from the direction of the opening of the air intake pipe 103 to its interior, the sum of the areas between the inclined plates 4 is consistent with the diameter of the air intake pipe 103, which increases the shielding effect of the inclined plate 4 on the dust, and the inclined plate 4 is inclined toward the outside of the air intake pipe 103, so that the dust on the inclined plate 4 will slide away from the filter plate 2 due to gravity, reducing the dust in the airflow that contacts the filter plate 2, thereby reducing the possibility of the filter plate 2 being blocked by dust.

[0024] like Figure 3 , Figure 5 and Fig.11 As shown, in the second embodiment, a ring plate 5 is installed in the air inlet pipe 103, and a notch is opened on the ring plate 5 for air flow to pass through. The ring plate 5 is in a truncated cone shape, and the notch penetrates the ring plate 5, so that the air flow can continue to move into the air inlet pipe 103 through the ring plate 5. The end of the ring plate 5 with a larger diameter faces the outside of the air inlet pipe 103, and the end of the ring plate 5 with a smaller diameter faces the filter plate 2, so that when the air flow passes through the ring plate 5, the flow speed of the air flow is increased by reducing the diameter of the ring plate 5; The rotating plate 6 is rotatably installed in the air intake pipe 103, and the rotating plate 6 is provided with a friction rod 7 for contacting the inner wall of the ring plate 5. The ring plate 5 and the friction rod 7 are both made of plastic. When the two rub against each other, static electricity is generated on the two. As a result, when the air passes through the ring plate 5, the dust inside the air flow is adsorbed by static electricity, which further reduces the possibility of dust adhering to the filter plate 2, thereby reducing the possibility of dust blocking the filter plate 2. In the process of contact and friction between the friction rod 7 and the ring plate 5, the dust inside the ring plate 5 is scraped and the dust on the ring plate 5 is scraped and gathered. When the dust is adsorbed and gathered into a group through static electricity, and the gravity of the dust group is greater than the static electricity adsorption force, it will slide down along the inclined surface of the inner wall of the ring plate 5. The air intake pipe 103 is provided with a channel on one side of the ring plate 5 close to the outlet of the air intake pipe 103. When the dust slides downward, it slides to the outside of the air intake pipe 103 through the channel, which reduces the possibility of dust accumulation in the air intake pipe 103. A transmission gear 8 meshing with a connecting gear 302 is rotatably installed in the intake pipe 103, a transmission rod 9 is installed on the rotating shaft of the transmission gear 8, a gear plate 10 is installed on the free end of the transmission rod 9, and a plurality of teeth 11 are provided on the rotating plate 6, which mesh with the teeth 11. When the connecting gear 302 rotates, the transmission gear 8 is also driven to rotate in the opposite direction. Since the transmission rod 9 is coaxially installed on the transmission gear 8, the gear plate 10 is driven to rotate through the transmission rod 9 when the transmission gear 8 rotates, and then the rotating plate 6 is driven to rotate through the meshing of the gear plate 10 and the teeth 11. Since the connecting gear 302 reciprocates in the intake pipe 103 as the scraper rod 3 reciprocates in the intake pipe 103, when the transmission gear 8, the transmission rod 9 and the gear plate 10 are driven to reciprocate in the intake pipe 103, the rotating plate 6 is also driven to reciprocate in the intake pipe 103, so that the friction rod 7 can rub with the ring plate 5 at a sufficient frequency, thereby increasing the feasibility of the device.

[0025] like Figure 3 , Figure 7 and Figure 8 As shown in the second embodiment, a vertical rod 13 is slidably installed in the air inlet pipe 103 through a return spring 12, and a spring telescopic rod 14 is installed on the free end of the vertical rod 13. Figure 1 From the main perspective, the vertical rod 13 is slidably installed in the air intake pipe 103 along the vertical direction, and the spring telescopic rod 14 includes two rod bodies, which are connected by a spring, one of which is used to accommodate the other rod body, and the telescopic end of the spring telescopic rod 14 changes along the horizontal direction; A receiving block 15 is installed on the telescopic end of the spring telescopic rod 14, and an oil storage chamber 16 for storing lubricating oil is provided in the receiving block 15. The receiving block 15 and the oil storage chamber 16 act as an oil tank. An oil filling port is also provided on the receiving block 15, and a plug is installed at the oil filling port of the receiving block 15 to keep the oil storage chamber 16 sealed. The oil filling port is provided at a position where the receiving block 15 opens toward the air intake pipe 103, so that the operator can add lubricating oil to the oil storage chamber 16 after the device has been used for a long time. A sliding block 17 is installed on the side wall of the accommodating block 15, and an expansion plate 28 is installed at the bottom of the vertical rod 13. A toggle plate 30 is slidably installed on the rotating plate 6 through an extrusion spring 29. A sleeve plate is installed on the rotating plate 6, and the extrusion spring 29 is installed in the sleeve plate and accommodates the toggle plate 30. The inner wall of the sleeve plate restricts the inner wall of the toggle plate 30 so that the toggle plate 30 can only approach or move away from the rotating plate 6 in a straight line direction. The sliding block 17 contacts the side of the inclined plate 4 facing the opening of the intake pipe 103. When the rotating plate 6 reciprocates, the expansion plate 28 is pressed by the toggle plate 30, so that the vertical rod 13 can drive the spring telescopic rod 14 to move downward. The toggle plate 30 is provided with a The inclined plane, when the rotating plate 6 is reset, the toggle plate 30 moves upward, and when the vertical rod 13 moves upward to the maximum limit, it cannot continue to move upward, and then the toggle plate 30 slides toward the inside of the sleeve plate through the guidance of the inclined plane, so that the expansion plate 28 cannot block the toggle plate 30, so that the toggle plate 30 can be smoothly reset. Through the above movement process, the vertical rod 13 drives the spring telescopic rod 14 and the sliding block 17 to reciprocate in the intake pipe 103. During the process, when the vertical rod 13 moves downward, the sliding block 17 gradually conflicts with the surface of the inclined plate 4. At this time, the deformation of the telescopic end of the spring telescopic rod 14 enables the sliding block 17 to maintain contact with the surface of the inclined plate 4. A movable block 1702 is slidably installed on the sliding block 17 by pushing the spring 1701, and a sponge block 1703 is installed on the movable block 1702. The movable block 1702 contacts the inclined plate 4 through the sponge block 1703. A connecting pipe 1704 is installed on the movable block 1702. The free end of the connecting pipe 1704 passes through the accommodating block 15 and is located in the oil storage chamber 16. A plurality of through openings 1705 are opened on the connecting pipe 1704, one of which is located at one end of the connecting pipe 1704 facing the oil storage chamber 16, and the remaining through openings 1705 face the sponge block 1703. A cotton strip is arranged in the connecting pipe 1704. In normal state, the through opening 1705 on the connecting pipe 1704 is not located in the oil storage chamber 16. When the sliding block 17 moves in the air intake pipe 103 along with the spring telescopic rod 14, the seawater is driven to move. The sponge block 1703 scrapes the surface of the inclined plate 4 to wipe off the dust on the surface of the inclined plate 4. When the sliding block 17 moves to the highest point along with the spring telescopic rod 14, it moves to a position close to the top of the air inlet pipe 103, where the distance between the inner walls of the air inlet pipe 103 is smaller than its diameter, so that the inner wall of the air inlet pipe 103 squeezes the free end of the movable block 1702, so that the movable block 1702 slides toward the direction close to the accommodation block 15, thereby driving the connecting pipe 1704 to move into the oil storage chamber 16, so that the lubricating oil in the oil storage chamber 16 enters the connecting pipe 1704 through the through port 1705, and the lubricating oil is conducted to the other through ports 1705 through the cotton strips arranged inside the connecting pipe 1704, so that the lubricating oil can contact the sponge block 1703 from the through port 1705; During use, the vertical rod 13 reciprocates in the air intake pipe 103 to drive the spring telescopic rod 14 and the sliding block 17 to reciprocate on the inclined plate 4, and the dust on the inclined plate 4 is scraped by the sliding block 17. During the process, when the sliding block 17 drives the sponge block 1703 to move to the highest point, the lubricating oil in the oil storage chamber 16 is discharged, so that the lubricating oil can adhere to the sponge block 1703. The viscosity of the lubricating oil increases the cleaning effect of the sponge block 1703 on the dust. In addition, when the sponge block 1703 moves on the inclined plate 4, a lubricating oil film is also attached to the inclined plate 4, so that the inclined plate 4 can better absorb dust, thereby reducing the possibility of dust contacting the filter plate 2 and reducing the possibility of the filter plate 2 being blocked.

[0026] like Figure 7 As shown, in the second embodiment, a bowl-shaped plate 18 is installed at one end of the inclined plate 4 away from the opening of the air inlet pipe 103, and the cavity of the bowl-shaped plate 18 faces the inclined plate 4. A squeezing rod 19 is installed on the spring telescopic rod 14, and the squeezing rod 19 is used to resist the bowl-shaped plate 18. The bowl-shaped plate 18 is made of iron or other elastic materials. When in use, when the vertical rod 13 drives the spring telescopic rod 14 to reciprocate in the air inlet pipe 103, the position of the squeezing rod 19 in the air inlet pipe 103 is changed, so that the squeezing rod 19 reciprocates and squeezes the bowl-shaped plate 18, so that the bowl-shaped plate 18 is deformed and restored, and then the deformation and recovery of the bowl-shaped plate 18 causes the inclined plate 4 to vibrate, so that when too much dust accumulates on the inclined plate 4, the dust can be better separated from the inclined plate 4 by vibration, thereby increasing the practicality of the device.

[0027] like Fig. 9 As shown, in the second embodiment, a containing shell 20 is installed in the mounting shell 1, and the containing shell 20 is used to contain lubricating oil. An inlet connected to the air inlet pipe 103 is opened on the containing shell 20, and an air outlet pipe 21 for communicating with the air outlet 102 is installed on the containing shell 20. The axis of the opening in the containing shell 20 is in a horizontal direction. When in use, when air enters the mounting shell 1 through the air inlet pipe 103, it enters the containing shell 20 through the inlet, and is cleaned again by the lubricating oil in the containing shell 20, and then discharged through the air outlet pipe 21. If the mounting shell 1 is connected to the gear box at this time, the air is discharged into the gear box through the air outlet pipe 21, and the air flow will also carry some particles of the lubricating oil, so that the air flow can also lubricate the gears in the gear box, thereby increasing the practicality of the device. by Figure 1 From the main perspective, one end of the air outlet pipe 21 located in the housing 20 is in a horizontal direction, so that the lubricating oil in the housing 20 will not be affected by gravity and discharged into the gear box in large quantities, thereby increasing the practicality of the device; The housing shell 20 is provided with an oil filling pipe which penetrates the mounting shell 1. A one-way valve is provided in the oil filling pipe so that the lubricating oil can only enter the housing shell 20 in one direction along the oil filling pipe, thereby reducing the possibility of the lubricating oil flowing back. A plug is inserted in the oil filling pipe. When the device is used for a long time, the lubricating oil is added to the housing shell 20 through the oil filling pipe. When the external airflow passes through the lubricating oil in the containing shell 20, the lubricating oil can reduce the airflow, so that the airflow can enter the gear box more smoothly, reducing the possibility of air pressure changes in the gear box due to excessive air flow rate.

[0028] Embodiment 3 like Figure 1 - Fig.12 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, the extrusion rod 19 is rotatably mounted on the telescopic end of the spring telescopic rod 14, and a rubber sleeve 22 is provided on the outer sleeve of the extrusion rod 19. When the extrusion rod 19 extrudes the bowl-shaped plate 18, the friction between the extrusion rod 19 and the bowl-shaped plate 18 is reduced through the rotation of the extrusion rod 19 itself, and the obstruction of the bowl-shaped plate 18 to the movement of the extrusion rod 19 is reduced. The extrusion rod 19 contacts the bowl-shaped plate 18 through the rubber sleeve 22, and the wear between the extrusion rod 19 and the bowl-shaped plate 18 when they contact is reduced through flexible contact, thereby increasing the service life of the device.

[0029] In the third embodiment, a horizontal plate 23 is installed in the air intake pipe 103, and a through hole 24 is opened on the horizontal plate 23 for accommodating the vertical rod 13. When in use, the side wall of the vertical rod 13 is blocked by the inner wall of the through hole 24, so that the vertical rod 13 slides in the vertical direction along a straight path when sliding, thereby increasing the stability of the vertical rod 13 when in use.

[0030] In embodiment three, a rubber block 25 is installed at the end of the impact rod 203, and the impact rod 203 contacts the filter plate 2 through the rubber block 25. When the impact rod 203 collides with the filter plate 2, the rubber block 25 flexibly contacts the filter plate 2, so that the filter plate 2 can vibrate, while reducing the wear of the filter plate 2 and increasing the service life of the device.

[0031] like Fig.13 and Fig.14As shown, the present application also provides a gearbox, in some embodiments, including any of the gearbox ventilation devices described above, and also including an outer box body 26, the mounting shell 1 is mounted on the outer box body 26, a gear set is mounted inside the outer box body 26, a gear rod that rotates and penetrates the outer box body 26 is mounted on the gear set, the outer box body 26, the gear rod and the gear set form a transmission device that is consistent with the gearbox in the prior art, and a ventilation port 27 is opened on the outer box body 26, and there are two ventilation ports 27, one of which is connected to the air inlet 101, and the other ventilation port 27 is connected to the air outlet 102 is connected. When in use, the air outlet 102 on the mounting shell 1 is connected with one of the ventilation ports 27 through the air outlet pipe 21, so that outside air can enter the outer box body 26. Since a one-way valve is provided in the air outlet 102, the air flow in the outer box body 26 cannot enter the air outlet pipe 21 through the air outlet 102, and since a one-way valve is also provided in the air inlet 101, the outside gas cannot enter the outer box body 26 through the tube body connected to the air inlet 101, thereby reducing the possibility of dust entering the outer box body 26 and increasing the practicability of the device.
