Description

Technical Field

[0001] This invention relates to the field of tractor technology, specifically to an automatic cruise shock absorption device for monorail tractors. Background Technology

[0002] A tractor is a self-propelled power machine used to tow and drive work machinery to complete various mobile tasks. It consists of three main parts: an engine, a chassis, and electrical equipment. Tractors are classified by function and purpose into agricultural, industrial, and special-purpose tractors. A monorail tractor is a tractor with only one front wheel, which provides support and steering. To ensure the stability of a monorail tractor, a shock-absorbing structure is usually installed at the front wheel.

[0003] Currently, monorail tractors are mostly used for transporting agricultural products. This means that monorail tractors often travel in fields with a lot of dust and mud. Since the telescopic connection of the monorail tractor's shock absorption structure is always in a sliding state, the lubrication effect of the connection is particularly important to reduce wear. However, after a long period of use, a lot of dust, mud and other impurities will accumulate at the connection, which not only affects the lubrication of the connection and increases sliding wear, reducing the service life of the shock absorption structure, but also makes it difficult to clean and inconvenient to use.

[0004] To address the above issues, an automatic cruise shock absorption device for monorail tractors was proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic cruise shock absorption device for monorail tractors. By using this device, the problem in the background is solved that after long-term use, a large amount of dust, dirt and other impurities accumulate at the connection points of the monorail tractor shock absorption structure. This not only affects the lubrication of the connection points, increases sliding wear, and reduces the service life of the shock absorption structure, but also makes cleaning troublesome and difficult.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic cruise shock absorption device for a monorail tractor, comprising a middle connecting plate, an upper drive shaft fixedly installed at the center of the top surface of the middle connecting plate, shock-absorbing telescopic columns fixedly installed at both ends of the bottom surface of the middle connecting plate, and connecting protrusions fixedly installed on the bottom surface of the shock-absorbing telescopic columns, a scraper ring embedded in the telescopic part of the middle of the shock-absorbing telescopic column, and Z-shaped clamping rods slidably installed in the inner cavities at both ends of the middle of the shock-absorbing telescopic column.

[0007] Furthermore, the shock-absorbing telescopic column includes a mounting sleeve and a telescopic column that is elastically slidably mounted at the opening of the inner cavity of the mounting sleeve by a strong spring.

[0008] Furthermore, a double-through annular groove is provided on the top surface of the mounting sleeve, and L-shaped sliding holes are respectively provided on the outer walls of both ends of the upper end of the mounting sleeve. Z-shaped clamping rods are respectively slidably installed in the L-shaped sliding holes, and the upper ends of the L-shaped sliding holes are connected to the top surface of the mounting sleeve. A snap-fit ​​bottom groove is provided in the middle of the bottom surface of the inner cavity of the L-shaped sliding hole, and a triangular snap block is fixedly installed on the upper inner wall of the outer end of the snap-fit ​​bottom groove. An L-shaped inner through hole is provided on the inner wall of the middle inner side of the inner cavity of the L-shaped sliding hole, and the upper end of the L-shaped inner through hole is connected to the double-through annular groove.

[0009] Furthermore, arc-shaped grooves are respectively provided on the inner walls of both sides of the L-shaped sliding hole cavity.

[0010] Furthermore, a circular mounting hole is provided at the lower center of the connecting protrusion.

[0011] Furthermore, the scraping ring comprises two independent semicircular rings, which are spliced ​​together.

[0012] Furthermore, the Z-shaped clamping rod includes a Z-shaped clamping rod and a pair of limiting balls respectively disposed on the outer wall of the lower end of the Z-shaped clamping rod. The limiting balls are respectively disposed in the arc-shaped sliding groove. An L-shaped locking block is elastically and slidably installed in the inner cavity of the lower end of the Z-shaped clamping rod. An L-shaped upper push rod is fixedly installed on the outer wall of the middle part of the inner end of the lower end of the Z-shaped clamping rod, and the L-shaped upper push rod is slidably installed in the L-shaped inner through hole.

[0013] Furthermore, an L-shaped through hole is provided on the outer wall of the middle part of the lower end of the Z-shaped pressure rod, and the lower end of the L-shaped through hole is provided through the bottom surface of the Z-shaped pressure rod.

[0014] Furthermore, the L-shaped locking block includes a pressing push block and a connecting locking block fixedly installed on the bottom surface of the pressing push block, and the connecting locking block is engaged with the triangular locking block. The pressing push block is elastically slidably installed at the upper inner cavity opening of the L-shaped through hole by a reset spring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting a Z-shaped clamping rod, the scraper ring can be pressed and fixed at the middle extension point of the shock-absorbing telescopic column. When the shock-absorbing telescopic column extends and retracts, the scraper ring can scrape off and clean the impurities on its output end. When the staff needs to clean the dust and impurities, they can push the Z-shaped clamping rod, so that the Z-shaped clamping rod loses its pressing and fixing effect on the scraper ring. Then the scraper ring can be removed for cleaning. The cleaning is convenient and quick, ensuring the lubrication of the connection of the shock-absorbing telescopic column, reducing sliding wear, and improving the service life of the shock-absorbing structure.

[0025] Combination Figure 1 The monorail tractor automatic cruise shock absorption device of the present invention includes a middle connecting plate 1. An upper drive shaft 2 is fixedly installed at the middle of the top surface of the middle connecting plate 1. Shock-absorbing telescopic columns 3 are fixedly installed at both ends of the bottom surface of the middle connecting plate 1. Connecting protrusions 4 are fixedly installed on the bottom surface of the shock-absorbing telescopic columns 3, and the wheels are installed between the connecting protrusions 4. A scraper ring 5 is embedded in the telescopic part of the middle of the shock-absorbing telescopic column 3. Z-shaped clamping rods 6 are slidably installed in the inner cavities at both ends of the middle of the shock-absorbing telescopic column 3. By setting the Z-shaped clamping rods 6, the scraper ring 5 can be pressed and fixed at the telescopic part of the middle of the shock-absorbing telescopic column 3. When the shock-absorbing telescopic column 3 telescopics, the impurities on its output end can be scraped off and cleaned by the scraper ring 5.

[0026] The present invention will be further described below with reference to embodiments.

[0027] Example 1:

[0028] Please see Figures 1-6 The shock-absorbing telescopic column 3 includes a mounting sleeve 31 and a telescopic column 32 that is elastically slidably mounted on the opening of the inner cavity of the mounting sleeve 31 via a strong spring 33. The strong spring 33 enables shock absorption for the tractor. A double-ring groove 311 is provided on the top surface of the mounting sleeve 31. L-shaped sliding holes 312 are respectively provided on the outer walls of both ends of the upper end of the mounting sleeve 31. Z-shaped clamping rods 6 are respectively slidably mounted through and in the L-shaped sliding holes 312, and the upper ends of the L-shaped sliding holes 312 are connected and positioned on the top surface of the mounting sleeve 31. The L-shaped sliding holes 312... A snap-fit ​​groove 313 is provided at the middle of the bottom surface of the cavity, and a triangular snap-fit ​​block 314 is fixedly installed on the upper inner wall of the outer end of the snap-fit ​​groove 313. An L-shaped inner through hole 315 is provided on the inner wall of the middle inner side of the L-shaped sliding hole 312, and the upper end of the L-shaped inner through hole 315 is connected to the double through ring groove 311. Through the setting of the double through ring groove 311, the scraper ring 5 can be embedded in the mounting sleeve 31, ensuring the overall aesthetics of the shock-absorbing telescopic column 3. Arc-shaped sliding grooves 3121 are respectively provided on the inner walls of both sides of the L-shaped sliding hole 312.

[0029] A circular mounting hole 41 is provided at the lower center of the connecting protrusion 4, through which the wheel can be movably mounted between the connecting protrusions 4.

[0030] The scraper ring 5 includes two independent semicircular rings 51, which are spliced ​​together. The inner side of the scraper ring 5 is set to fit against the outer wall of the telescopic column 32, so that when the telescopic column 32 is extended or retracted, the scraper ring 5 can scrape and remove dust and impurities from the surface of the telescopic column 32.

[0031] The Z-type clamping rod 6 includes a Z-type clamping rod 61 and a pair of limiting balls 62 respectively disposed on the outer walls of the lower ends of the Z-type clamping rod 61. The limiting balls 62 are respectively disposed in the arc-shaped sliding groove 3121. An L-shaped locking block 63 is elastically and slidably installed in the inner cavity of the lower end of the Z-type clamping rod 61. An L-shaped through hole 611 is provided on the outer wall of the middle part of the lower end of the Z-type clamping rod 61, and the lower end of the L-shaped through hole 611 is disposed through the bottom surface of the Z-type clamping rod 61. The L-shaped locking block 63 includes a pressing push block 631 and a connecting locking block 633 fixedly installed on the bottom surface of the pressing push block 631. The connecting locking block 633 is engaged with the triangular locking block 314. The pressing push block 631 is elastically and slidably installed at the upper end inner cavity opening of the L-shaped through hole 611 by a return spring 632.

[0032] After prolonged use, the scraper ring 5 will accumulate a large amount of dust and impurities. When the staff needs to clean the dust and impurities, they can use their fingers to squeeze and push the squeezing push block 631 inward, causing the squeezing push block 631 to move the connecting block 633 inward together. The connecting block 633 will then separate from the triangular block 314. At this time, pushing the Z-shaped pressure rod 61 upward will cause the upper end of the Z-shaped pressure rod 61 to lose its clamping and fixing effect on the scraper ring 5. By removing the scraper ring 5 from the double-through annular groove 311, the dust and impurities on the scraper ring 5 can be thoroughly cleaned. The cleaning is convenient and quick, ensuring the lubrication of the connection between the mounting sleeve 31 and the telescopic column 32, reducing sliding wear, and improving the service life of the shock-absorbing structure.

[0033] When it is necessary to fix the scraper ring 5 in the double-ring groove 311, the Z-shaped pressure rod 61 can be pushed down to insert the connecting block 633 into the bottom groove 313. At this time, the upper end of the Z-shaped pressure rod 61 will press against the top surface of the scraper ring 5. Then, the L-shaped block 63 is released. Under the elastic force of the return spring 632, the automatic engagement between the connecting block 633 and the triangular block 314 can be achieved. The operation is convenient and quick, and it is easy to disassemble and assemble the scraper ring 5.

[0034] Example 2:

[0035] Please see Figures 1-3 An L-shaped upper push rod 64 is fixedly installed on the outer wall of the middle part of the inner end of the lower end of the Z-shaped pressure rod 61, and the L-shaped upper push rod 64 is slidably installed in the L-shaped inner through hole 315.

[0036] When the Z-shaped pressure rod 61 is pushed upward, it can drive the L-shaped upper push rod 64 to move upward as well, so that the upper end of the L-shaped upper push rod 64 pushes the semi-circular ring 51 out of the double through ring groove 311, which makes it convenient for the operator to remove the scraper ring 5. Multiple effects can be completed at the same time with one action, making the operation convenient and quick, and ensuring the aesthetics of the shock absorption structure.
