DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0027] In order to solve the technical problems in the background technology, the following rice huller gear transmission lubrication mechanism is provided:

[0028] Combination Figure 1-Figure 5 As shown, the rice husker gear transmission lubrication mechanism provided by the utility model comprises a shell 1 and a transmission body 8, the top of the transmission body 8 is fixedly mounted with the shell 1, the bottom of the shell 1 is docked with a plurality of docking assemblies 6, and the docking assemblies 6 are connected with the interior of the transmission body 8, the front of the shell 1 is provided with an oil storage chamber 14, the back of the shell 1 is provided with an installation chamber 11, the interior of the installation chamber 11 is docked with a buffer-type oil guide assembly 2 extending from the shell 1, the top of the shell 1 is fixedly mounted with a shell 2 3, the interior of the shell 2 3 is respectively provided with a transmission chamber 31 and a pressurizing chamber 32, and the transmission chamber 31 and the pressurizing chamber 32 are jointly equipped with a pressurizing assembly 4;

[0029] By fixing the housing 1 on the gearbox body 8, it is easier to lubricate the gearbox body 8. The oil storage chamber 14 is used to store the lubricating oil. By docking and cooperating with the gearbox body 8 through multiple groups of docking assemblies 6, it can be effectively ensured that multiple transmission points in the gearbox body 8 will be lubricated. The buffered oil guide assembly 2 not only realizes the oil guide operation of the device for the lubricating oil, ensuring that multiple transmission points in the gearbox body 8 will be lubricated, but also can adjust them according to the actual oil injection amount of the actual lubrication points, which not only ensures the lubrication demand of the gearbox, but also reduces the waste of lubricating oil. The pneumatic pressurization operation is realized by the pressurizing assembly 4, and the air collection and pressurization operation is completed by using the cam principle to complete the real-time oil injection operation of the lubricating oil. The pneumatic pressurization method can not only ensure the stable injection of the lubricating oil, but also facilitate personnel to control the oil injection process in real time.

[0030] The buffer oil guide assembly 2 includes a buffer component 21, an oil inlet pipe 22, and an oil outlet pipe 23. The oil inlet pipe 22 is docked and installed inside the installation chamber 11, and the buffer component 21 is docked and installed on the top of the oil inlet pipe 22. The oil outlet pipe 23 connected to the oil storage chamber 14 is docked and installed on one side of the buffer component 21; the pressurizing assembly 4 includes a pressurizing component 41, an air inlet component 42, and an air outlet component 43. The pressurizing component 41 is docked and installed inside the transmission chamber 31, and the driving end of the pressurizing component 41 extends into the pressurizing chamber 32. The air inlet component 42 is fixedly installed in the middle of the pressurizing chamber 32, and the air outlet component 43 is docked and installed on one side of the shell 2 3. The air outlet component 43 is connected to the pressurizing chamber 32 and the pressurizing component 41 respectively.

[0031] During this period, the pressurizing component 41 is started to pressurize the inside of the pressurizing chamber 32, and as the actual air pressure inside the pressurizing chamber 32 increases, the pressure will be pushed to the inside of the oil storage chamber 14, so that the lubricating oil in the oil storage chamber 14 is injected into the docking assembly 6, and the lubricating oil is guided to the required lubrication point through the docking assembly 6, and when the actual oil injection amount of the lubrication point needs to be adjusted, the buffer component 21 can be adjusted to increase or decrease the buffering strength of the buffer component 21, so that the oil conduction amount of the lubricating oil can be suppressed to complete variable control. Embodiment 2

[0032] like Figure 1 and Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0033] In this embodiment, a mounting seat 13 connected to the gearbox body 8 is fixedly mounted on the bottom of the housing 1, and a sealing plate 12 is butt-jointedly mounted on the front of the housing 1.

[0034] During this period, the assembly connection between the housing 1 and the gearbox body 8 is completed through the mounting seat 13 to achieve the support operation of the housing 1, and at the same time, the sealing plate 12 is connected to the housing 1 to complete the sealing of the oil storage chamber 14.

[0035] In this embodiment, the pressurizing component 41 includes a motor 411, a guide wheel 412, a driving arm 413, a guide rod 414, and a piston 1 415. The guide wheel 412 is docked and installed inside the transmission chamber 31, the motor 411 is fixedly installed on the front of the shell 2 3, and the output end of the motor 411 is installed and connected to the guide wheel 412. The driving arm 413 is docked and installed on the guide wheel 412, and the end of the driving arm 413 is docked and installed with a guide rod 414 extending into the pressurizing chamber 32, and the end of the guide rod 414 is docked and installed with a piston 1 415.

[0036] During this period, the motor 411 is started, and the output end of the motor 411 drives the guide wheel 412 to rotate. The rotation of the guide wheel 412 completes the driving of the driving arm 413 and the guide rod 414, prompting the guide rod 414 to drive the piston 415 at the end to reciprocate in the pressurized chamber 32. At this time, the external air enters and is pushed into the other side through the air intake component 42 for air collection.

[0037] In this embodiment, the air intake component 42 includes a partition 421 and a one-way air guide valve 422; the air outlet component 43 includes an air outlet pipe 431 and an electrically controlled air valve 432, the partition 421 is fixedly installed inside the pressurized chamber 32, and the one-way air guide valve 422 is fixedly installed on the partition 421, an air outlet pipe 431 is dockedly installed on one side of the shell 2 3, and the two ends of the air outlet pipe 431 are respectively connected to the pressurized chamber 32 and the oil storage chamber 14, and the electrically controlled air valve 432 is fixedly installed on the air outlet pipe 431, the top of the shell 2 3 is dockedly installed with a pressure gauge 5 extending into the pressurized chamber 32, and the pressure gauge 5 is located between the air outlet pipe 431 and the partition 421, and the top of the shell 2 3 is dockedly installed with a one-way air intake valve connected to the pressurized chamber 32.

[0038] By combining the above contents, the guide rod 414 drives the piston 415 at the end to reciprocate in the pressurized chamber 32, and then the external air enters and pushes the entering air into the other side of the partition 421 through the one-way air guide valve 422 to complete the air collection. During this period, the air pressure value can be mastered through the barometer 5;

[0039] When personnel need to relieve pressure and add oil, they can electrically control the opening and closing of the air valve 432 to complete the operation of guiding the lubricating oil. Embodiment 3

[0040] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0041] In this embodiment, the docking assembly 6 includes a mounting head 61 and a docking sleeve 62. A plurality of mounting heads 61 are dockedly mounted on the top of the gearbox body 8, and a docking sleeve 62 connected to the oil outlet pipe 23 is dockedly mounted on the top of the mounting head 61.

[0042] The mounting head 61 is docked and installed with a plurality of transmission points on the top of the gearbox body 8 . After installation, the mounting head 61 is installed and connected with the oil outlet pipe 23 through the docking sleeve 62 .

[0043] In this embodiment, the top of the shell 1 is docked with an oil filling assembly 7 extending into the oil storage chamber 14, and the oil filling assembly 7 includes a measuring strip 71 and an oil filling port 72. The top of the shell 1 is docked with an oil filling port 72 connected to the oil storage chamber 14, and the top of the oil filling port 72 is docked with a measuring strip 71 extending into the oil storage chamber 14, and a sealing cap is fixedly installed on the top of the measuring strip 71, and the sealing cap is docked with the oil filling port 72.

[0044] During this process, the personnel first rotate and disassemble the sealing cap to separate it from the oil filling port 72. During the disassembly, the sealing cap simultaneously brings out the measuring strip 71, and then the personnel can perform the oil filling operation in the oil storage chamber 14.

[0045] Furthermore, personnel can also observe the oil soaking amount of the measuring strip 71 by removing the sealing cap to judge the actual storage amount of the lubricating oil.

[0046] In this embodiment, the buffer component 21 includes an oil guide cylinder 211, a piston 212, a spring 213, an adjusting cap 214, and a connecting rod 215. One end of the oil inlet pipe 22 is connected to the oil storage chamber 14, and the other end is docked with the oil guide cylinder 211. The top of the shell 1 is docked with a connecting rod 215 extending into the oil guide cylinder 211, and the bottom end of the connecting rod 215 is docked with the piston 212. The spring 213 is mounted on the connecting rod 215, and the adjusting cap 214 is docked with the connecting rod 215 at the top of the spring 213.

[0047] During this period, due to the different transmission points inside the gearbox body 8, the required amount of lubricating oil is also different. At this time, the personnel can rotate the adjusting cap 214 to complete the squeezing or loosening of the spring 213. In this way, when the lubricating oil enters the oil guide cylinder 211, the lubricating oil will resist and push the piston 212 under the action of air pressure. Since the spring 213, the adjusting cap 214, and the connecting rod 215 on each group of buffer components 21 have different tightness, the amount of lubricating oil entering is also different.
