[0002] Tractors are important mechanical equipment widely used in agricultural production and engineering construction. They have strong power and traction, and can complete various heavy tasks, such as ploughing, sowing, transportation, etc. In the agricultural field, the emergence of tractors has greatly improved agricultural production efficiency and reduced the labor intensity of farmers. It can be used in conjunction with various agricultural tools to realize the mechanization and automation of agricultural production.

[0003] In the prior art, the transmission wheel inside the reducer will wear out due to various factors during long-term operation. The wear of the transmission wheel will produce impurities such as metal debris, which will mix into the lubricating oil inside the reducer, causing the lubricating oil to be contaminated. In addition, the heat generated by the wear and the influence of the external environment may cause the temperature and humidity inside the reducer to change, which may easily lead to the emulsification of the lubricating oil. After the lubricating oil is emulsified, its lubricating performance will be greatly reduced, and it will not be able to effectively protect the parts inside the reducer, further aggravating the wear and damage of the parts.

[0004] Therefore, we propose a tractor with an improved speed reducer assembly to solve the above problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0024] 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.

[0025] In the utility model, a tractor with an improved reducer assembly is provided. Figure 1 - Figure 4, including a reducer assembly 2 arranged at the bottom of the tractor body 1, and a lubricating oil circulation component arranged at the bottom of the reducer assembly 2, the lubricating oil circulation component including a filter housing 3, an oil guide surface 9 is provided on one side of the filter housing 3, a cavity is provided inside the filter housing 3, a spiral shaft 11 for lubricating oil diversion is provided in the cavity, an oil outlet hole 8 connected to the inside of the cavity is provided on the top of the filter housing 3, an oil inlet hole 10 connected to the inside of the cavity is provided on the surface of the oil guide surface 9, and a filter screen 14 for lubricating oil filtering is provided in the cavity.

[0026] The spiral shaft 11 in the filter housing 3 provides power for the flow of the lubricating oil. The spiral shaft 11 allows the lubricating oil to flow along a specific path in the cavity, avoiding the disordered flow of the lubricating oil, thereby ensuring that the lubricating oil can circulate more efficiently inside the reducer. This orderly circulation can ensure that each component that needs lubrication can get sufficient supply of lubricating oil in time, minimize the wear and friction caused by insufficient lubrication, and extend the service life of the reducer. In addition, a filter screen 13 is arranged inside the filter housing 3, and the filter screen 13 can effectively capture and remove various impurities in the lubricating oil, including metal debris, dust and other particles generated by wear. If these impurities are not filtered out in time, they will enter the various components of the reducer with the lubricating oil, aggravate the wear of the components, and cause the performance of the reducer to decline and the life of the reducer to be shortened. The existence of the filter screen 13 ensures the cleanliness of the lubricating oil, provides a pure lubrication environment for the reducer, and greatly reduces the wear and failure caused by impurities.

[0027] Specifically, the reducer assembly 2 includes a reducer assembly housing 201, a reducer assembly gear set 202 is arranged inside the reducer assembly housing 201, one side of the reducer assembly gear set 202 is transmission-connected to the driving shaft 12, and the driving shaft 12 is connected to the transmission rod 4 through the reduction gear.

[0028] The transmission connection between the reducer assembly gear set and the driving shaft 12, and the connection between the driving shaft 12 and the transmission rod 4 through the reduction gear, ensure the stable transmission of power.

[0029] Specifically, one end of the screw shaft 11 is connected to the input shaft 6 , and the input shaft 6 is transmission-connected to one end of the transmission rod 4 via a gear.

[0030] The function of the screw shaft 11 is to guide the lubricating oil so that it can flow more smoothly in the filter housing 201. Through the transmission connection between the input shaft 6 and the transmission rod 4, the screw shaft 6 can continue to work as the tractor runs, continuously promoting the flow of lubricating oil, and improving the circulation efficiency of the lubricating oil.

[0031] Specifically, one side of the oil guide surface 9 is arc-shaped, and the arc-shaped surface of the oil guide surface 9 corresponds to the position of the reducer assembly gear set 202 .

[0032] The oil guide surface 9 is designed to be arc-shaped, which can better fit the shape of the gear set of the reducer assembly. When the gear set is running, the splashed lubricating oil can flow along the arc-shaped surface and contact the oil guide surface with a larger area, thereby improving the collection efficiency of the lubricating oil.

[0033] Specifically, a threaded hole is formed on the outer wall of the sealing plate 7 , and a fixing bolt 5 is disposed in the threaded hole. The fixing bolt 5 is fixed to the outer wall of the reducer assembly housing 201 .

[0034] The outer wall of the sealing plate 7 is provided with a threaded hole and is fixed to the outer wall of the reducer assembly housing by means of fixing bolts 5, so as to effectively seal the reducer assembly 2 and prevent the leakage of lubricating oil.

[0035] Specifically, one end of the filter housing 3 is a pointed end, and the pointed end of the filter housing 3 fits on the inside of the reducer assembly housing 201 .

[0036] The tip of the filter housing 3 fits inside the reducer assembly housing 201, which can be closer to the source of the lubricating oil and collect the lubricating oil that needs to be filtered in time. The tip design of the filter housing 3 enables it to better fit the internal shape of the reducer assembly housing 201, making full use of the space inside the reducer, making the entire structure more compact.

[0037] Specifically, the filter 14 is prism-shaped on the outside, a through hole is provided at the center of the tip of the filter 14 , the inner diameter of the through hole at the tip of the filter 14 is larger than the outer diameter of the spiral shaft 11 , and a block matching the filter 14 is provided inside the cavity of the filter housing 3 .

[0038] The filter screen 14 can be fixed inside the filter housing 3 by a block, and the spiral shaft 11 can pass through the through hole of the filter screen 14. When the lubricating oil passes through the filter screen 14, the filter screen 14 can filter the lubricating oil. In addition, the prism-shaped filter screen 14 and the inner wall of the filter housing 3 form a space for storing impurities, which is used to store impurities in the lubricating oil.

[0039] The working principle of the utility model is that the reducer assembly gear set 202 in the reducer assembly 2 is driven by the driving shaft 12. The driving shaft 12 is connected to the transmission rod 4 through the reduction gear, and drives the screw shaft 11 to rotate through the input shaft 6. At the same time, when the reducer assembly gear set 202 is running, the lubricating oil will splash. At this time, the oil guide surface 9 of the filter housing 3 plays a role. The oil guide surface 9 is arc-shaped, and its position corresponds to the reducer assembly gear set 202, which can more effectively collect the splashed lubricating oil. The oil inlet hole 10 on the oil guide surface 9 is connected to the cavity inside the filter housing 3, and the lubricating oil enters the cavity through the oil inlet hole 10. One end of the spiral shaft 11 is connected to the input shaft 6, and the input shaft 6 is connected to one end of the transmission rod 4 through a gear. When the transmission rod 4 rotates, the input shaft 6 is driven to rotate, and then the spiral shaft 11 starts to rotate. The rotation of the spiral shaft 11 allows the lubricating oil entering the cavity to flow along its spiral direction, and the lubricating oil is sucked in through the oil inlet hole 10. After that, the lubricating oil is discharged through the oil outlet hole 8 to achieve the diversion function, ensuring that the lubricating oil can pass through the subsequent filtering links in an orderly manner. Under the diversion effect of the spiral shaft 11, the lubricating oil flows to the filter screen 14. The outside of the filter screen 14 is a prism shape, and a through hole is opened at the center of the tip, and the inner diameter of the through hole is larger than the outer diameter of the spiral shaft 11. A card block matching the filter screen 14 is arranged inside the cavity of the filter housing 3, so that the filter screen 14 can be stably installed in the cavity. When the lubricating oil passes through the filter 14, the impurities therein are filtered out, thereby ensuring the cleanliness of the lubricating oil. The filtered lubricating oil continues to flow and finally flows out through the oil outlet 8 on the top of the filter housing 3. The oil outlet 8 is connected to the inside of the cavity, so that the filtered lubricating oil can return to the reducer assembly 2, providing sufficient lubrication for the various components of the reducer assembly gear set 202, reducing wear between components, and extending the service life of the reducer. The sealing plate 7 is fixed to the outer wall of the reducer assembly housing 201 by the fixing bolts 5, which plays a sealing role.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
