DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0031] In a specific embodiment, Figure 1-Figure 2 As shown,…

[0032] A box body 1 and an input shaft 2 rotatably mounted on the left side of the box body 1;

[0033] An output shaft 3 is rotatably mounted on the front end of the box body 1 , and a sealing frame 4 is fixedly mounted on the lower end of the box body 1 .

[0034] When using the high-load transfer gearbox for construction machinery, first place the gearbox at the position where it needs to work. After installing the gear at the required position, the gearbox can be put into operation. During the operation, the oil inside the sealing frame 4 lubricates the rotating parts inside the box body 1, thereby reducing the wear between the internal structures of the gearbox. Through continuous lubrication of the oil, the load-bearing capacity between the rotating structures inside the box body 1 can be increased, thereby enabling the gearbox to perform high-load work.

[0035] In one specific embodiment, Figure 1-Figure 5 As shown;

[0036] A filtering structure is provided at the lower end of the housing 1, and the filtering structure can achieve the effect of separating impurities in the internal oil of the transfer gearbox;

[0037] A driving motor 5 and an auger rod 6 are arranged inside the filtering structure. The driving motor 5 is fixedly installed on the outside of the sealing frame 4, and the auger rod 6 is fixedly installed on the output end of the driving motor 5, and the auger rod 6 is rotatably connected to the sealing frame 4;

[0038] A fixing pipe 7 is fixedly installed inside the sealing frame 4, and the fixing pipe 7 is sleeved on the outside of the auger rod 6, and an inlet and outlet 8 are equidistantly opened inside the end of the fixing pipe 7 close to the driving motor 5;

[0039] A filter frame 9 is fixedly mounted on one end of the sealing frame 4 away from the driving motor 5, and a circulation pipe 10 is fixedly mounted on the upper end of the filter frame 9, and the end of the circulation pipe 10 away from the filter frame 9 is located inside the sealing frame 4, and the end of the fixed pipe 7 away from the driving motor 5 is located inside the sealing frame 4;

[0040] Two groups of filter plates 14 are slidably installed inside the sealing frame 4, and a support spring 15 is fixedly installed between the two groups of filter plates 14. A discharge port 13 is opened at the lower end of the filter frame 9, and a rotating cylinder 11 is installed on the internal thread of the discharge port 13, and a receiving bottle 12 is fixedly installed at the lower end of the rotating cylinder 11.

[0041] When the high-load transfer gearbox for construction machinery is used, the driving motor 5 drives the auger rod 6 to rotate inside the fixed pipe 7, so that the oil inside the sealing frame 4 enters the fixed pipe 7 through the inlet and outlet 8, and the oil flows inside the fixed pipe 7 to the inside of the filter frame 9 and enters the inside of the sealing frame 4 again through the circulation pipe 10, thereby completing the circulation process;

[0042] During this process, the oil will impact the filter plate 14 close to the fixed tube 7 and make the filter plate 14 slide inside the filter frame 9. At this time, a gap will be generated between the filter plate 14 and the filter frame 9 to facilitate the entry of impurities into the filter frame 9. At this time, the impurities will enter the interior of the containing bottle 12 through the discharge port 13 and the rotating cylinder 11 inside the filter frame 9, thereby discharging the impurities from the circulation inside the gear box to prevent the impurities from affecting the circulation of the oil inside the gear box.

[0043] Based on the above embodiments, Figure 1-Figure 2 and Figure 6-Figure 7 As shown;

[0044] A disassembly structure is provided on the outer side of the rotating cylinder 11, and the disassembly structure can realize the effect of disassembling the containing bottle 12 for cleaning;

[0045] A limit spring 18 and a limit plate 19 are arranged inside the disassembly and assembly structure. The limit spring 18 and the limit plate 19 are sleeved on the outside of the rotating cylinder 11, and the limit spring 18 is located at the lower end of the limit plate 19, and the limit plate 19 is fixedly connected to the rotating cylinder 11. A moving disk 20 is slidably installed on the outside of the rotating cylinder 11, and the moving disk 20 is located between the limit spring 18 and the limit plate 19, and a limit rod 21 is fixedly installed at an equal angle on the upper end of the moving disk 20, and the limit rod 21 passes through the limit plate 19;

[0046] A fixed cylinder 16 and a limiting hole 17 are provided inside the disassembly and assembly structure. The fixed cylinder 16 is fixedly installed at the lower end of the filter frame 9, and the fixed cylinder 16 is located outside the discharge port 13. The limiting hole 17 is provided inside the fixed cylinder 16, and the limiting hole 17 is located outside the limiting rod 21.

[0047] After the impurities inside the gear box enter the interior of the receiving bottle 12, the impurities inside the receiving bottle 12 can be cleaned, thereby facilitating the cleaning of the impurities. In this process, it is necessary to press the moving disk 20 to slide downward on the outside of the rotating cylinder 11, and the downward movement of the moving disk 20 will drive the limiting rod 21 to move downward, and the downward movement of the limiting rod 21 will squeeze the limiting spring 18 and cause it to contract. At the same time, the limiting rod 21 will move away from the limiting hole 17. After the limiting rod 21 is separated from the limiting hole 17, the rotating cylinder 11 and the receiving bottle 12 can be rotated. At this time, the rotating cylinder 11 and the receiving bottle 12 can be removed from the inside of the filter frame 9. At this time, the impurities inside the receiving bottle 12 can be cleaned, thus completing the process of removing impurities inside the gear box oil, effectively improving the convenience of using the gear box and increasing the overall practicality.
