Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a tractor front axle bracket. Background Technology

[0002] The front axle bracket is an important component of the tractor's front axle system, primarily used to support and secure the front axle, ensuring a stable connection between the front axle and the vehicle body. Its main functions are to bear the weight of the front axle, transmit the load from the front axle, and assist in the operation of the tractor's suspension system.

[0003] Existing front axle brackets prevent the tractor's nose from lifting by installing fixed counterweights. However, most of the time, tractors do not need counterweights or require only light counterweights. In such cases, fixed counterweights will increase the overall load on the tractor, resulting in poor applicability. Utility Model Content

[0004] The technical problem this utility model aims to solve is that existing front axle brackets prevent the tractor's front end from lifting by installing fixed counterweights. However, most of the time, the tractor does not need counterweights or the required counterweights are light. In this case, the fixed counterweights will increase the overall load on the tractor, resulting in poor applicability.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tractor front axle bracket, including a front axle bracket body, wherein an adjustment device is provided on one side of the front axle bracket body. The adjustment device can control the counterweight value by installing or removing a corresponding number of counterweight plates in several rectangular slots on the counterweight block according to the actual working state of the tractor, so as to adapt to the load conditions of different working states of the tractor and improve the applicability of the front axle bracket body.

[0006] Preferably, the adjusting device includes a counterweight, a mounting groove is provided on one side of the front axle bracket body, the counterweight is inserted into the inner wall of the mounting groove, and a mounting mechanism is provided between one side of the counterweight and the inner wall of the mounting groove; a plurality of rectangular grooves are provided on one side of the counterweight; a plurality of protective mechanisms are provided, wherein the protective mechanisms are installed in the inner wall of the rectangular grooves for sealing and protecting the inner wall of the rectangular grooves; and a counterweight plate is inserted into the inner wall of the rectangular grooves, wherein a limit mechanism is provided between one side of the counterweight plate and both sides of the counterweight.

[0007] The aforementioned components achieve the following effects: By setting an adjustment device, when the front axle bracket body is installed on the front of the tractor to support and fix the front axle, its main function is to bear the weight of the front axle, transmit the load from the front axle, and assist in the operation of the tractor's suspension system. During use, depending on the working condition of the tractor and the required counterweight load, the counterweight blocks can be inserted into the inner wall of the mounting slot and then fixed by the mounting mechanism. Then, the corresponding number of counterweight plates are inserted into the corresponding rectangular slots, retracted by the protective mechanism in the rectangular slots, and then the counterweight plates are fixed in the rectangular slots by the limiting mechanism. This allows for flexible adjustment of the weight of the counterweight blocks, enabling flexible adjustment of the overall load according to the tractor's usage, ensuring stable operation of the tractor under different working conditions, and improving the applicability of the front axle bracket body.

[0008] Preferably, the protective mechanism includes a protective plate, which is slidably mounted in the inner wall of the rectangular groove; and two springs, wherein the two ends of the springs are respectively fixedly mounted on one side of the protective plate and one side of the inner wall of the rectangular groove.

[0009] The effect achieved by the above components is as follows: by setting up a protective mechanism, when the counterweight plate is inserted into the rectangular slot, it will squeeze the protective plate to slide downward in the rectangular slot, causing the spring to contract, which facilitates the installation of the counterweight plate. When the counterweight plate is removed, the protective plate will seal the opening of the rectangular slot under the reset action of the spring, making it difficult for external dust and impurities to enter the rectangular slot and avoid clogging it.

[0010] Preferably, the protective mechanism further includes two telescopic rods, wherein the outer surface of the telescopic rods penetrates the inner wall of the spring and the two ends are respectively fixedly installed on one side of the protective plate and one side of the inner wall of the rectangular groove.

[0011] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use.

[0012] Preferably, the limiting mechanism includes two first protrusions, one side of which is fixedly mounted on one side of the counterweight plate; a plurality of second protrusions, one side of which is symmetrically fixedly mounted on both sides of the counterweight; two rotating blocks, one end of which is rotatably mounted on one side of two opposing second protrusions; two elastic iron blocks, one side of which is inclinedly fixed on one side of the rotating block, and one end of which abuts against one side of the first protrusion; and a plurality of second torsion springs, the inner walls of which are respectively sleeved on the outer surfaces of both ends of the two rotating blocks, and both ends are respectively fixedly mounted on one side of the second protrusion and the rotating block.

[0013] The effect achieved by the above-mentioned components is as follows: By setting a limiting mechanism, when the counterweight plate is inserted into the rectangular slot, the rotating block is first rotated to a certain angle on the two second protrusions, causing the second torsion spring to deform. Then the counterweight plate is inserted into the rectangular slot. At this time, the rotating block is released so that under the reset action of the second torsion spring, one end rotates to the top of the counterweight plate. Then, it is pressed down on one end, causing the elastic iron block against the first protrusion to deform. When the elastic iron block completely leaves the first protrusion, one end will abut against one side of the first protrusion, fixing and limiting the counterweight plate inserted into the rectangular slot, so that the counterweight plate installed on the tractor is not easy to shake or fall off during use.

[0014] Preferably, the casual clothing mechanism includes two locking rods, one end of which is rotatably mounted on one side of the counterweight, and the inner wall of the mounting groove is symmetrically provided with locking holes, wherein one end of the locking rod is inserted into the inner wall of the locking hole; and a first torsion spring, wherein the first torsion spring is inserted into the inner wall of one end of the locking rod, and both ends are respectively fixedly mounted on one side of the inner wall of the locking rod and one side of the counterweight.

[0015] The effect achieved by the above-mentioned components is as follows: by setting up a convenient mounting mechanism, when inserting the counterweight into the mounting slot, the locking rod is first rotated to a certain angle, causing the torsion spring to deform, and then inserted into the mounting slot, so that one side of the locking rod abuts against the inner wall of the mounting slot. Then the counterweight is inserted, so that the locking rod can be inserted into the locking hole until one end of the locking rod is completely through the locking hole. Under the reset action of the torsion spring, the locking rod is rotated 90 degrees, and the counterweight is fixedly installed in the mounting slot on the front axle bracket body, which facilitates the use of counterweight loads on the tractor.

[0016] Preferably, one end of the lever has a trapezoidal longitudinal section, wherein the trapezoidal end of the lever is located at the end furthest from the counterweight.

[0017] The effect achieved by the above-mentioned components is that by designing one end of the clamp rod in a trapezoidal shape, the area of ​​one end of the clamp rod can be reduced, making it easier to quickly align with the clamp hole and insert it, thus facilitating installation.

[0018] Preferably, the casual fitting mechanism further includes several bolts, and several threaded grooves are symmetrically opened on one side of the front axle bracket body, wherein one end of the bolt is helically inserted into the inner wall of one end of the clamp and the inner wall of the threaded groove.

[0019] The effect achieved by the above components is as follows: by setting bolts and threaded grooves, after the clamp rod is inserted into the clamp hole, it can be rotated to a certain angle under the reset action of the first torsion spring. This allows the hole on one side of the clamp rod to be quickly aligned with the threaded groove, making it easier for the bolt to be screwed in and used for secondary positioning and fixing, thus making the clamping of the counterweight block more secure and stable.

[0020] The beneficial effects of this utility model are:

[0021] By setting an adjustment device, when the front axle bracket body is installed on the head of the tractor to support and fix the front axle, its main function is to bear the weight of the front axle, transmit the load from the front axle, and assist in the operation of the tractor's suspension system.

[0032] Figure 1-6 The tractor front axle bracket shown includes a front axle bracket body 1. An adjustment device 2 is provided on one side of the front axle bracket body 1. The adjustment device 2 can control the counterweight value by installing or removing a corresponding number of counterweight plates 26 in several rectangular slots 24 on the counterweight block 22 according to the actual working state of the tractor, so as to adapt to the load conditions of different working states of the tractor and improve the applicability of the front axle bracket body 1.

[0033] Figure 1-6 The adjustment device 2 shown includes a counterweight 22, an installation groove 21 on one side of the front axle bracket body 1, wherein the counterweight 22 is inserted into the inner wall of the installation groove 21, and a mounting mechanism 23 is provided between one side of the counterweight 22 and the inner wall of the installation groove 21. Several rectangular grooves 24 are provided on one side of the counterweight 22; several protective mechanisms 25 are installed in the inner wall of the rectangular grooves 24 to seal and protect the inner wall of the rectangular grooves 24; and a counterweight plate 26 is inserted into the inner wall of the rectangular grooves 24. A limit mechanism 27 is provided between one side of the counterweight plate 26 and both sides of the counterweight 22. By setting the adjustment device 2, when the front axle bracket body 1 is installed on the head of the tractor to support and fix the front axle, its main function is to bear the weight of the front axle, transmit the load from the front axle, and assist the tractor's suspension system in operation. During use, according to the working condition of the tractor and the required counterweight load, the counterweight block 22 can be inserted into the inner wall of the mounting groove 21 and then fixed by the mounting mechanism 23. Then, the corresponding number of counterweight plates 26 can be inserted into the corresponding rectangular grooves 24 and retracted by the protective mechanism 25 in the rectangular grooves 24. Then, the counterweight plates 26 can be limited and fixed in the rectangular grooves 24 by the limiting mechanism 27. In this way, the weight of the counterweight block 22 can be flexibly adjusted to achieve flexible adjustment of the overall load according to the use of the tractor, ensuring the stable operation of the tractor under different working conditions and improving the applicability of the front axle bracket body 1.

[0034] Figure 1-6 The protective mechanism 25 shown includes a protective plate 252, which is slidably installed in the inner wall of the rectangular groove 24; and two springs 251, with their ends respectively fixed to one side of the protective plate 252 and one side of the inner wall of the rectangular groove 24. By setting up the protective mechanism 25, when the counterweight plate 26 is inserted into the rectangular groove 24, it will compress the protective plate 252, causing it to slide downwards within the groove, thus contracting the springs 251 and facilitating the installation of the counterweight plate 26. When the counterweight plate 26 is removed, the protective plate 252, under the restoring action of the springs 251, will seal the opening of the rectangular groove 24, preventing external dust and impurities from entering and clogging it. The protective mechanism 25 also includes two telescopic rods 253, the outer surface of which penetrates the inner wall of the springs 251, with its ends respectively fixed to one side of the protective plate 252 and one side of the inner wall of the rectangular groove 24. By setting the telescopic rod 253, the inner wall of the spring 251 can be supported and reinforced, making it less prone to damage during use.

[0035] Figure 1-6 The limiting mechanism 27 shown includes two first protrusions 271, one side of which is fixedly mounted on one side of the counterweight plate 26; several second protrusions 272, one side of which is symmetrically fixedly mounted on both sides of the counterweight block 22; two rotating blocks 273, one end of which is rotatably mounted on one side of two opposing second protrusions 272; two elastic iron blocks 274, one side of which is inclinedly fixed on one side of the rotating block 273, and one end of which abuts against one side of the first protrusion 271; and several second torsion springs 275, the inner walls of which are respectively sleeved on the outer surfaces of both ends of the two rotating blocks 273, and both ends are fixedly mounted on one side of the second protrusions 272 and the rotating blocks 273. By setting a limiting mechanism 27, when inserting the counterweight plate 26 into the rectangular slot 24, the rotating block 273 is first rotated to a certain angle on the two second protrusions 272, causing the second torsion spring 275 to deform. Then, the counterweight plate 26 is inserted into the rectangular slot 24. At this time, the rotating block 273 is released so that under the reset action of the second torsion spring 275, one end rotates to the top of the counterweight plate 26. Then, it is pressed down on one end so that the elastic iron block 274 on the first protrusion 271 deforms. When the elastic iron block 274 completely leaves the first protrusion 271, one end will abut against one side of the first protrusion 271, fixing and limiting the counterweight plate 26 inserted into the rectangular slot 24, so that the counterweight plate 26 is not easy to shake or fall off during the use of the tractor.

[0036] Figure 1-6The casual clothing mechanism 23 shown includes two locking rods 232, one end of which is rotatably mounted on one side of the counterweight 22. The inner wall of the mounting groove 21 is symmetrically provided with locking holes 231, one end of which is inserted into the inner wall of the locking hole 231. A first torsion spring 233 is inserted into the inner wall of one end of the locking rod 232, and both ends are fixedly mounted on one side of the inner wall of the locking rod 232 and one side of the counterweight 22, respectively. By setting up the portable mechanism 23, when inserting the counterweight 22 into the mounting slot 21, the locking rod 232 is first rotated to a certain angle, causing the torsion spring to deform. Then, it is inserted into the mounting slot 21, with one side of the locking rod 232 abutting against the inner wall of the mounting slot 21. The counterweight 22 is then inserted, allowing the locking rod 232 to be inserted into the locking hole 231. After one end of the locking rod 232 completely exits the locking hole 231, the torsion spring's reset action rotates the locking rod 232 ninety degrees, fixing the counterweight 22 in the mounting slot 21 on the front axle bracket body 1, facilitating the use of counterweight loads on the tractor. One end of the locking rod 232 has a trapezoidal longitudinal section, with this trapezoidal end positioned away from the counterweight 22. By designing one end of the locking rod 232 as a trapezoid, the area of ​​that end is reduced, facilitating quick alignment with the locking hole 231 and insertion, thus simplifying installation. The casual mechanism 23 also includes several bolts 234. Several threaded grooves 235 are symmetrically opened on one side of the front axle bracket body 1. One end of the bolt 234 is screwed into the inner wall of one end of the clamp rod 232 and the inner wall of the threaded groove 235. By setting the bolts 234 and the threaded grooves 235, after the clamp rod 232 is inserted into the clamp hole 231, it can be rotated to a certain angle under the reset action of the first torsion spring 233. This allows the hole on one side of the clamp rod to quickly align with the threaded groove 235, making it easier for the bolts 234 to be screwed in and used for secondary positioning and fixation, thus making the clamp rod 232 more firmly and stably fixed.

[0037] Working principle: When the front axle bracket body 1 is installed on the front of the tractor to support and fix the front axle, its main function is to bear the weight of the front axle, transmit the load from the front axle, and assist the tractor's suspension system in operation. During use, depending on the working condition of the tractor and the required counterweight load, the lever 232 is first rotated to a certain angle, causing the torsion spring to deform, and then inserted into the mounting groove 21, so that one side of the lever 232 abuts against the inner wall of the mounting groove 21. Then, the counterweight block 22 is inserted, so that the lever 232 can be inserted into the locking hole 231 until one end of the lever 232 is completely through the locking hole 231. Under the reset action of the torsion spring, the lever 232 is rotated 90 degrees, fixing the counterweight block 22 in the mounting groove 21 on the front axle bracket body 1. First, the rotating block 273 is placed on the two second protrusions 272. The counterweight plate 26 is inserted into the rectangular groove 24 by rotating the upper part to a certain angle, causing the second torsion spring 275 to deform. The protective plate 252 is then pressed down in the rectangular groove 24, causing the spring 251 to contract, which facilitates the installation of the counterweight plate 26. Then, the rotating block 273 is released so that one end rotates to the top of the counterweight plate 26 under the reset action of the second torsion spring 275. Then, it is pressed down on one end so that the elastic iron block 274 on the first protrusion 271 deforms. When the elastic iron block 274 completely leaves the first protrusion 271, one end will abut against one side of the first protrusion 271, fixing the counterweight plate 26 inserted into the rectangular groove 24. This allows for flexible adjustment of the weight of the counterweight block 22, enabling flexible adjustment of the overall load according to the tractor's usage, ensuring the stable operation of the tractor under different working conditions, and improving the applicability of the front axle bracket body 1.
