Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil for a tractor transmission case, in particular to a lubricating oil cooling and filtering device for a tractor transmission case. Background Technique

[0002] A tractor refers to a self-propelled power machine used to tow and drive working machinery to complete various mobile operations, and can also be used as a fixed operation power. It consists of systems or devices such as an engine, transmission, running, steering, hydraulic suspension, power output, electrical instrument, driving control, and towing.

[0003] In use, lubricating oil is required for multiple components, which plays roles such as reducing friction and protecting mechanical components to extend the service life of the components. Lubricating oil cooling and filtering is mainly used to remove impurities such as dust, metal particles, carbon deposits, and soot particles in the engine oil to protect the engine, ensure the cleanliness and stability of the lubricating oil, and thus extend the service life of mechanical equipment.

[0004] Currently, most of the filtration of lubricating oil on the market is to transport it through a pipeline to a filtering device for treatment through a filter screen. However, during the filtration process, when a large amount of lubricating oil enters the device for filtration and cooling treatment, the lubricating oil will accumulate on the surface of the filter screen, making it impossible for the lubricating oil to pass through quickly, reducing the filtration efficiency. And after long-term use, the surface of the filter screen gradually adsorbs full of metal debris, causing blockage and thus affecting the filtration effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a lubricating oil cooling and filtering device for a tractor transmission case to solve the problem that most of the existing cooling and filtering devices filter through a filter screen, and during the process, the lubricating oil will accumulate on the surface of the filter screen, making it impossible for the lubricating oil to pass through quickly, reducing the filtration efficiency and being inconvenient to handle the lubricating oil impurities adhered to the surface of the filter screen, resulting in blockage and affecting the filtration effect. To achieve the above purpose, the utility model provides the following technical solution: A lubricating oil cooling and filtering device for a tractor transmission case, including a lubricating oil cooling box for the transmission case, a pipeline for oil transportation is connected to the side wall of the lubricating oil cooling box for the transmission case, a pipeline for oil drainage is connected to the end of the lubricating oil cooling box for the transmission case, an impact rod is slidably connected to the side wall of the lubricating oil cooling box for the transmission case, a reciprocating mechanism is provided at the end of the impact rod for driving the impact rod to slide horizontally back and forth, a sliding rod capable of sliding horizontally back and forth is slidably arranged on the top of the lubricating oil cooling box for the transmission case, a cleaning brush is fixed to the bottom of the sliding rod, a filter screen is slidably connected to the inside of the lubricating oil cooling box for the transmission case, a spring is fixed to the end of the filter screen, and the spring is fixedly connected to the inner wall of the lubricating oil cooling box for the transmission case.

[0006] Preferably, a sliding groove for facilitating the horizontal sliding of the sliding rod is opened on the top of the lubricating oil cooling box for the transmission case.

[0033] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a chute 101 for facilitating the horizontal sliding of the sliding rod 6 is opened on the top of the transmission case lubricating oil cooling tank 1.

[0034] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, control valves are installed above both the lubricating oil pipe 2 and the drain pipe 3.

[0035] It should be noted that the control valve is a prior art in this field, and its detailed structure belongs to the prior art and is not unique, so it will not be elaborated. The control valve is used to control the feeding and discharging operations of the lubrication. The lubricating oil pipe 2 and the drain pipe 3 are in a closed state when not in use and are only opened when in use.

[0036] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the reciprocating mechanism 5 includes a mounting plate 51 fixed to the side wall of the transmission case lubricating oil cooling tank 1. A first motor 52 is fixed to the end of the mounting plate 51. The output end of the first motor 52 is fixedly connected with a transmission shaft 53. An active gear 54 is sleeved outside the transmission shaft 53. A driven gear 55 is meshed with the bottom of the active gear 54. A support shaft 56 is rotatably connected to the middle of the driven gear 55. A convex rod 57 is fixed to the surface of the driven gear 55. An annular plate 58 is sleeved outside the convex rod 57.

[0037] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the support shaft 56 is fixedly connected to the mounting plate 51, the transmission shaft 53 is rotatably connected to the mounting plate 51. An annular groove 59 facilitating the sliding of the convex rod 57 is provided inside the annular plate 58. The annular plate 58 is fixedly connected to the impact rod 4, and the impact rod 4 is at the same horizontal plane as the filter screen 8.

[0038] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a support block 61 is fixed to the top of the transmission case lubricating oil cooling tank 1. A second motor 62 is fixed to the end of the support block 61. A lead screw 63 is fixed to the output end of the second motor 62. A slider 64 is slidably sleeved on the outside of the lead screw 63. The slider 64 is fixedly connected to the slide bar 6.

[0039] It should be noted that there are two support blocks 61, which are respectively installed at both ends of the lead screw 63. A guide rod is provided in the middle thereof. The slider 64 is slidably sleeved thereon. The slider 64 is guided to slide by the guide rod to prevent the slider 64 from rotating along with the lead screw 63. Since this structure is a prior art in this field, it will not be elaborated here.

[0040] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a leakage groove 10 is provided at the bottom of the transmission case lubricating oil cooling tank 1. A dust collection box 11 is slidably connected to the bottom of the transmission case lubricating oil cooling tank 1. The leakage groove 10 is communicated with the dust collection box 11.

[0041] It should be noted that the transmission case lubricating oil cooling tank 1 has a cooling structure inside. However, since the main innovation point of this case does not lie in the cooling, its positioning only includes, so it will not be elaborated in detail.

[0042] It should be noted that the specific model specifications of the first motor 52 and the second motor 62 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the prior art in this field, so it will not be elaborated here.

[0043] It should be noted that the diameter of the cleaning brush 7 is greater than or equal to the diameter of the filter screen 8. The cleaning brush 7 is attached to the surface of the filter screen 8. The surface of the filter screen 8 is cleaned by the horizontal sliding of the cleaning brush 7.

[0044] The usage method and advantages of the present utility model: When the tractor transmission case lubricating oil cooling and filtering device is working, the working process is as follows:

[0045] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the transmission box lubricating oil cooling box 1 is connected to the tractor transmission box and used. Through the operation of the control valve, the lubricating oil enters the transmission box lubricating oil cooling box 1 through the oil delivery pipe 2 for cooling and filtering treatment;

[0046] Start the first motor 52 to drive the transmission shaft 53 to drive the driving gear 54 to rotate. When the driving gear 54 rotates, it meshes with the driven gear 55. The driven gear 55 is forced to rotate around the support shaft 56. When rotating, the convex rod 57 on its surface rotates immediately and slides in the annular groove 59 of the annular plate 58. As the driven gear 55 continues to rotate, the annular plate 58 is forced to drive the impact rod 4 to slide back and forth, thereby impacting the filter screen 8. The filter screen 8 is forced to slide and stretch the spring 9. Through the cooperation of the spring 9 and the impact rod 4, the filter screen 8 shakes back and forth, thereby shaking and filtering the lubricating oil accumulated on its surface, enabling the lubricating oil to pass through quickly and improving the filtering efficiency;

[0047] After long-term use, the filter screen 8 needs to be cleaned. When cleaning, start the second motor 62 to drive the lead screw 63 to rotate. When the lead screw 63 rotates, the slider 64 sleeved outside it slides immediately and drives the slide bar 6 at the bottom to slide horizontally along the chute 101 on the top of the transmission box lubricating oil cooling box 1, so that the cleaning brush 7 at the bottom of the slide bar 6 slides horizontally along the surface of the filter screen 8, thereby cleaning the metal debris adsorbed on the surface of the filter screen 8. The cleaned debris leaks into the dust collection box 11 through the leakage groove 10, enabling the filter screen 8 to be cleaned quickly, avoiding the blockage of the filter screen 8 by metal debris and thus affecting the subsequent filtering effect, improving the use effect, and the dust collection box 11 can be slid out, and the staff can centrally clean the debris to avoid the metal debris leaking into the bottom of the cooling box and affecting the internal use environment.
