Abstract
Description
Technical Field
[0001] This utility model relates to the field of tractor manufacturing technology, and in particular to a fuel supply throttling device for tractor chassis break-in. Background Technology
[0002] The tractor chassis, also known as the transmission system, consists of assemblies such as the gearbox, rear axle, power output, and left and right final drive devices. It is the core component of the tractor, serving as the control center for changing the speed, braking, steering, and outputting the tractor's power source. At the same time, it is also the main frame for assembling or connecting other tractor components (including the engine, cab, front axle, drive wheels, etc.), hence the name chassis.
[0003] After the tractor chassis is manufactured and assembled, it needs to be broken in under no-load or load conditions before the complete machine is assembled. During the break-in process, the engine needs to be simulated to input power, and a certain speed and torque need to be input to make the tractor chassis simulate the no-load or load operation process during use. Gear shifting and speed change are performed to find defects such as misaligned gears, missing gears, inconvenient operation, abnormal noises, etc. The chassis is initially broken in to remove various impurities inside the transmission system and grind each transmission component.
[0004] During the break-in process of a tractor chassis, a fuel supply throttling device is generally used to supply oil, as described in Chinese Patent Publication No. CN205078751U, which describes a fuel supply throttling device for tractor chassis break-in. However, during the fuel supply process, the lubricating oil carried out cannot be filtered and recovered. The unfiltered lubricating oil still has some use value, but if it is not recycled, it will lead to resource waste. If it is directly discharged, it will cause irreversible damage to the environment. Therefore, a fuel supply throttling device for tractor chassis break-in is proposed to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] like Figure 1-6 As shown, the present invention proposes a fuel supply throttling device for tractor chassis break-in, comprising a fuel supply tank 1, a pump body mechanism 8 on the top of the fuel supply tank 1, a fuel filling pipe connected to the top of the fuel supply tank 1, an mounting block 2 fixedly installed on the top of the fuel supply tank 1, a filter box 3 fixedly installed on the top of the mounting block 2, a return pipe 4 connected to the top of the filter box 3, an oil delivery pipe 5 connected to the fuel supply tank 1 on the left side of the filter box 3, an internal threaded sleeve 6 fixedly installed on the right side of the filter box 3, and a filtering mechanism 7 provided inside the filter box 3.
[0026] In this utility model, the pump body mechanism 8 can send the lubricating oil inside the oil supply tank 1 into the throttling device, and then into the tractor chassis through the throttling device. The lubricating oil is used to break in the tractor chassis. The filter box 3 can be installed through the mounting block 2. The lubricating oil used up inside the tractor chassis can be sent to the filter box 3 through the return pipe 4. The filter mechanism 7 inside the filter box 3 filters the lubricating oil. Finally, the filtered lubricating oil is sent back into the oil supply tank 1 through the oil delivery pipe 5, which facilitates the recycling of lubricating oil.
[0027] like Figure 1-6As shown, in an optional embodiment, the filter mechanism 7 includes a block 71 slidably connected to the inside of the filter box 3, two connecting plates 72 fixedly installed on the left side of the block 71, and a U-shaped frame 73 fixedly installed on the left side of the two connecting plates 72. The U-shaped frame 73 is adapted to the inside of the filter box 3. A filter plate 74 is slidably connected inside the filter box 3. The top of the filter plate 74 contacts the top wall inside the filter box 3. A limiting component 75 is provided inside the U-shaped frame 73 to limit the filter plate 74. A guide component 76 is provided at the bottom of the U-shaped frame 73. An installation component 77 is provided on the right side of the filter box 3. The installation component 77 is connected to the block 71 and is used to install the block 71.
[0028] It should be noted that the right side of the filter box 3 can be sealed by the block 71, and the filter plate 74 can be installed by the two connecting plates 72 and the U-shaped frame 73. The end of the return pipe 4 near the filter box 3 is located on the right side of the filter plate 74. The used lubricating oil is filtered by the filter plate 74. The guide assembly 76 can guide the filter plate 74 to ensure that the filter plate 74 can be stably installed inside the U-shaped frame 73. The block 71 can be installed and removed by the installation assembly 77, so that the two connecting plates 72, the U-shaped frame 73 and the filter plate 74 can be removed from the filter box 3, which facilitates the disassembly of the filter plate 74, making it easy to clean or replace the filter plate 74 and ensuring the filtration effect of the filter plate 74.
[0029] When the two connecting plates 72, the U-shaped frame 73 and the filter plate 74 are installed into the filter box 3, the guide component 76 can guide the block 71, so that the installation direction of the block 71 can be determined. This ensures that when the filter plate 74 is installed, the opening of the U-shaped frame 73 faces upward, thus ensuring that the filter plate 74 can be stably placed inside the U-shaped frame 73.
[0030] like Figure 4 As shown, in an optional embodiment, the limiting component 75 includes limiting grooves 751 formed on the front and rear side walls of the inner cavity of the U-shaped frame 73. The tops of the two limiting grooves 751 are connected to the outside. Limiting blocks 752 are fixedly installed on the front and back of the filter plate 74. The two limiting blocks 752 are slidably connected to the inside of the two limiting grooves 751 respectively.
[0031] When the filter plate 74 is slidably connected inside the U-shaped frame 73, the filter plate 74 can be guided by the limiting groove 751 and the limiting block 752, and the filter plate 74 can also be supported after installation to prevent the filter plate 74 from tilting or falling off.
[0032] like Figure 3 and Figure 5As shown, in an optional embodiment, the guide assembly 76 includes a guide block 761 and a guide groove 762. The guide groove 762 is formed in the inner bottom wall of the filter box 3. The right side of the guide groove 762 is connected to the outside. The guide block 761 is fixedly installed on the bottom of the block 71 and is slidably connected to the inside of the guide groove 762.
[0033] When the block 71 is slidably connected to the inside of the filter box 3, the block 71 is guided by the guide block 761 and the guide groove 762 to ensure that the block 71 can only be slidably connected to the inside of the filter box 3 from the direction of displacement. When installed in this orientation, the opening of the U-shaped frame 73 faces upward, thereby preventing the U-shaped frame 73 and the filter plate 74 from detaching from the U-shaped frame 73 due to gravity when the U-shaped frame 73 and the filter plate 74 are installed with the block 71.
[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in an optional embodiment, the mounting assembly 77 includes a cover plate 771 located on the right side of the filter box 3. An external threaded ring 772 is fixedly mounted on the left side of the cover plate 771. The external threaded ring 772 is threaded into the inside of the internal threaded ring sleeve 6. A mounting post 773 is rotatably connected to the left side of the cover plate 771. The left side of the mounting post 773 is fixedly connected to the right side of the block 71. A handle 774 is fixedly mounted on the right side of the cover plate 771.
[0035] When it is necessary to remove the block 71, the two connecting plates 72, the U-shaped frame 73, and the filter plate 74 from the filter box 3, the cover plate 771 can be rotated directly. The cover plate 771 will drive the external threaded ring 772 to rotate. When the external threaded ring 772 is disengaged from the internal threaded ring sleeve 6, the cover plate 771 can be pulled to the right by the handle 774. Under the action of the mounting column 773, the block 71, the two connecting plates 72, the U-shaped frame 73, and the filter plate 74 can be removed from the filter box 3. During the rotation of the cover plate 771, the mounting column 773 will not drive the block 71 to rotate, preventing the block 71 from limiting the rotation of the cover plate 771.
[0036] When it is necessary to install the block 71, the two connecting plates 72, the U-shaped frame 73, and the filter plate 74 from the filter box 3, the block 71, the two connecting plates 72, the U-shaped frame 73, and the filter plate 74 are installed into the filter box 3 through the guide block 761 and the guide groove 762. Then, the cover plate 771 is rotated in the opposite direction, and the external threaded ring 772 is threadedly connected to the internal threaded ring sleeve 6 to ensure the stability of the installation of the block 71, the two connecting plates 72, the U-shaped frame 73, and the filter plate 74.
[0037] The block 71 is compatible with the filter box 3, and a sealing gasket is provided at the contact position between the block 71 and the inside of the filter box 3. The sealing gasket can prevent the lubricating oil inside the filter box 3 from leaking through the right side of the filter box 3.
[0038] After removing the block 71, two connecting plates 72, U-shaped frame 73, and filter plate 74 from inside the filter box 3, pull the filter plate 74 upwards. The filter plate 74 can be removed from inside the U-shaped frame 73 through the limiting groove 751 and the limiting block 752, making it convenient to clean or replace the filter plate 74, thereby ensuring the filtration effect of the filter plate 74.
[0039] like Figure 1 As shown, in an optional embodiment, the pump body mechanism 8 includes an oil pump 81 fixedly installed on the top of the oil supply tank 1. The oil inlet of the oil pump 81 is connected to an oil suction pipe 82 with one end connected to the inside of the oil supply tank 1, and the oil outlet of the oil pump 81 is connected to an oil supply pipe 83.
[0040] The oil pump 81 and the oil extraction pipe 82 can extract the lubricating oil from the oil supply tank 1, and then send the lubricating oil to the throttling device through the oil supply pipe 83, and then to the tractor chassis. The function and structure of the throttling device are specifically described in the prior art CN205078751U, and will not be elaborated on in this application.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
