Description

Technical Field

[0001] This utility model relates to the field of tractor front bracket technology, specifically to an adjustable support device for the front bracket. Background Technology

[0002] In existing tractors, the front bracket is used to connect the engine and the front drive axle. The specifications of the front drive axle and the required installation height are different in different tractor sizes. Since the existing front bracket is a one-piece structure with a fixed structure, it cannot be adapted to the required front drive axle. For front drive axles with different specifications and different installation height requirements, corresponding front brackets need to be specially designed and manufactured, resulting in high production costs for tractors.

[0003] Traditional front brackets typically distribute functions such as counterweight installation, front axle connection, and engine docking in a dispersed manner, resulting in a loose structure and cumbersome installation steps. This increases assembly steps and introduces the risk of insufficient rigidity. For accessories such as batteries, most designs fail to provide dedicated mounting positions, requiring additional brackets to fix them to other parts of the machine, compromising the overall structural compactness. Existing front brackets are usually custom-made for specific tractor models; when manufacturers release new models or users need to adjust the wheelbase, existing front brackets cannot be adjusted accordingly, necessitating a redesign and production of a new bracket. This approach increases production costs and time, failing to meet the demands of modern agricultural machinery for flexible, low-cost upgrades and modifications. Therefore, we propose an adjustable front bracket support device. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing front support brackets are typically custom-designed for specific tractor models. When manufacturers release new models or users need to adjust the wheelbase, the existing front support brackets cannot be adjusted accordingly, requiring a complete redesign and production of a new bracket. This approach increases production costs and time, and cannot meet the demands of modern agricultural machinery for flexibility and low-cost upgrades. To solve this problem, this invention provides an adjustable front support bracket device.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An adjustable front bracket support device includes a bracket main frame. The upper end of the bracket main frame is evenly provided with a plurality of frame through holes. The bottom of both sides of the plurality of frame through holes are provided with snap-fit ​​steps. A fixed top beam is fixedly connected between the two sides of the snap-fit ​​steps by an adjustable snap-fit ​​mechanism. The fixed top beam is set to fit against the top of the bracket main frame. A base mounting seat is fixedly connected to the center position of the upper end of the fixed top beam. The upper end of the inner cavity of the base mounting seat is provided with internal threads.

[0007] Furthermore, the adjusting clamping mechanism includes a fixed clamp and a movable clamp. The fixed clamp is fixedly connected to the fixed top beam, and the movable clamp is movably sleeved on the fixed top beam. The bottom outer sides of the fixed clamp and the movable clamp are fixedly connected with clamping protrusions corresponding to the clamping steps.

[0008] Furthermore, a clamp-fixing hydraulic telescopic rod is provided at the center of the opposite side of the fixed clamp and the movable clamp, and the rod sleeve and inner rod of the clamp-fixing hydraulic telescopic rod are fixedly connected to the fixed clamp and the movable clamp respectively. The center of the fixed top beam is embedded in the bottom of the inner cavity of the foundation mounting seat, and the rod sleeve of the extrusion oil supply hydraulic telescopic rod is connected to the rod sleeve of the clamp-fixing hydraulic telescopic rod through the embedded hose.

[0009] Furthermore, the upper end of the base mounting seat is threadedly connected to an adjustable mounting seat via a connecting screw, and the adjustable mounting seat is a bolt seat with an interchangeable upper center inner diameter.

[0010] Furthermore, the upper end of the base mounting seat is threadedly connected to a flange docking seat via a connecting screw, and a flange seat is provided at the upper end of the flange docking seat.

[0011] Furthermore, the length of the fixed top beam is greater than the width of the frame through hole, and rubber pads are fixedly connected to the inner walls on both sides of the frame through hole.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses an adjustable snap-fit ​​mechanism to fix the base mounting seat. In conjunction with equipment installation, the snap-fit ​​step securely fixes the top beam to the top of the main frame of the bracket, ensuring a tight fit. Afterwards, the equipment requiring support can be installed on the base mounting seat. When maintenance or replacement of the equipment supported on the base mounting seat is needed, operators can easily and quickly release the fixation using the adjustable snap-fit ​​mechanism, remove the base mounting seat from the main frame of the bracket, complete the necessary operations, and then reinstall and fix it. The entire process is simple and easy, greatly improving work efficiency.

[0014] 2. This utility model, by replacing the height-adjusting docking seats with different inner diameters and heights, can adapt to the installation needs of equipment of different sizes and models. When installing larger equipment, selecting a height-adjusting docking seat with a larger inner diameter ensures smooth installation; when installing smaller equipment, selecting a height-adjusting docking seat with a smaller inner diameter makes the installation more stable. Furthermore, by using height-adjusting docking seats of different heights, the height of the equipment can also be adjusted to meet the installation height requirements of different equipment, improving the versatility and flexibility of the device.

[0015] 3. This utility model, by setting a flange docking seat, allows for convenient docking and installation with equipment having a flange connection structure. When the equipment to be installed has a flange interface, simply install the flange docking seat on the base mounting base using docking connection bolts, then align the equipment's flange with the flange seat on the flange docking seat and secure it with bolts. This connection method is stable and reliable, can withstand large loads, and facilitates equipment installation and disassembly, further improving the applicability and convenience of the device. Furthermore, the flange docking seat can be replaced with different specifications and sizes according to actual needs to meet the connection requirements of different equipment.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Please see Figures 1-4 This utility model provides an adjustable front bracket support device, including a bracket main frame 1. The upper end of the bracket main frame 1 is evenly provided with a plurality of frame through holes 2. The bottom of both sides of the plurality of frame through holes 2 are provided with snap-fit ​​steps 3. The snap-fit ​​steps 3 on both sides are fixedly connected to a fixed top beam 5 through an adjustable snap-fit ​​mechanism. The fixed top beam 5 is set to fit against the top of the bracket main frame 1. The upper center position of the fixed top beam 5 is fixedly connected to a base mounting seat 7, and the upper end of the inner cavity of the base mounting seat 7 is provided with an internal thread.

[0023] The working principle and usage process of this utility model are as follows: First, the main frame 1 of the bracket is installed on the front side of the tractor. Since multiple frame through holes 2 are evenly distributed on the upper end of the main frame 1, the base mounting seat 7 can be fixed using an adjustable snap-fit ​​mechanism according to different equipment installation spacing and the number of mounting seats. In conjunction with equipment installation, the fixed top beam 5 is securely fixed to the top of the main frame 1 using snap-fit ​​steps 3, ensuring a tight fit. Then, the equipment requiring support can be installed on the base mounting seat 7. The internal thread on the upper end of the inner cavity of the base mounting seat 7 allows for easy connection with components with external threads, thus achieving stable support for different objects. Furthermore, the position of the fixed top beam 5 can be adjusted by adjusting the adjustable snap-fit ​​mechanism according to actual support height requirements, meeting diverse usage scenarios. This provides an adjustable support mechanism for equipment installation on the front bracket of different tractor models. When the manufacturer launches a new model or the user needs to adjust the wheelbase, there is no need to produce a new bracket. Only the position of the base mounting seat 7 needs to be adjusted according to the changes, reducing production costs and time.

[0024] When maintenance or replacement of the equipment supported on the base mounting base 7 is required, the operator can easily and quickly remove the base mounting base 7 from the main frame 1 of the bracket by adjusting the locking mechanism, complete the corresponding operation, and then reinstall and fix it. The whole process is simple and easy, which greatly improves work efficiency.

[0025] In this embodiment, preferably, the adjusting locking mechanism includes a fixed clamp 4 and a movable clamp 6. The fixed clamp 4 is fixedly connected to the fixed top beam 5, and the movable clamp 6 is movably sleeved on the fixed top beam 5. The outer bottom of both the fixed clamp 4 and the movable clamp 6 are fixedly connected with locking protrusions corresponding to locking steps 3. By adjusting the position of the movable clamp 6 on the fixed top beam 5, in conjunction with the fixed clamp 4, the locking protrusions can be precisely engaged with locking steps 3 at different positions, thereby flexibly adjusting the installation position of the fixed top beam 5 to adapt to the installation requirements of front drive axles of different tractors. When position adjustment is required, the operator only needs to push the movable clamp 6 to slide it along the fixed top beam 5. When the locking protrusion is aligned with the target position, the movable clamp 6 is released. The locking protrusions on the fixed clamp 4 and the movable clamp 6 work together to firmly fix the fixed top beam 5 onto the main frame 1 of the bracket, ensuring the stability and reliability of the device during use and facilitating switching operations.

[0026] In this embodiment, preferably, a clamp-fixing hydraulic telescopic rod 8 is provided at the center of the opposite side of the fixed clamp 4 and the movable clamp 6, and the sleeve and inner rod of the clamp-fixing hydraulic telescopic rod 8 are fixedly connected to the fixed clamp 4 and the movable clamp 6 respectively. A compression-supply hydraulic telescopic rod 9 is embedded at the bottom of the inner cavity of the foundation mounting base 7, corresponding to the center of the fixed top beam 5. The sleeve of the compression-supply hydraulic telescopic rod 9 is connected to the sleeve of the clamp-fixing hydraulic telescopic rod 8 through an internally embedded hose. A compression spring is provided inside the sleeve of the compression-supply hydraulic telescopic rod 9, which is provided with the clamp-fixing hydraulic telescopic rod 8 and the compression-supply hydraulic telescopic rod 9. The inner rod is pushed out and inserted into the central screw hole of the base mounting seat 7. When the equipment is installed on the base mounting seat 7, the connecting bolts or mating connecting screws 11 are screwed in, which can push the inner rod of the compression oil supply hydraulic telescopic rod 9 to retract. The hydraulic oil inside is squeezed into the rod sleeve of the clamp fixing hydraulic telescopic rod 8 through the embedded hose, pushing the inner rod of the clamp fixing hydraulic telescopic rod 8 to extend, thereby making the movable clamp 6 move away from the fixed clamp 4 until it is pressed against the locking step 3 on the opposite side. This ensures that the fixed top beam 5 can remain stable under a large load and will not shift or loosen, thus improving the load-bearing capacity and safety of the device. At the same time, when it is necessary to adjust the position of the fixed top beam 5, simply reduce the load on the base mounting seat 7. The compression oil supply hydraulic telescopic rod 9 retracts under its own elastic force, drawing the hydraulic oil back into the rod sleeve. The inner rod of the clamp fixing hydraulic telescopic rod 8 also retracts accordingly, increasing the distance between the fixed clamp 4 and the movable clamp 6. At this time, the movable clamp 6 can be moved easily to adjust the position of the fixed top beam 5.

[0027] In this embodiment, preferably, the upper end of the base mounting base 7 is threadedly connected to a height-adjustable docking seat 10 via a connecting screw 11, and the height-adjustable docking seat 10 is a bolt seat with an interchangeable upper center inner diameter. By replacing the height-adjustable docking seats 10 with different inner diameters and heights, it can adapt to the installation requirements of equipment of different sizes and models. When installing larger equipment, a height-adjustable docking seat 10 with a larger inner diameter is selected to ensure that the equipment can be installed smoothly; when installing smaller equipment, a height-adjustable docking seat 10 with a smaller inner diameter is selected to make the installation more stable. Moreover, by using height-adjustable docking seats 10 of different heights, the height of the equipment can also be adjusted to meet the installation height requirements of different equipment, improving the versatility and flexibility of the device.

[0028] In this embodiment, preferably, the upper end of the base mounting base 7 is threadedly connected to a flange docking seat 12 via a connecting screw 11, and the upper end of the flange docking seat 12 is provided with a flange seat. By providing the flange docking seat 12, it is easy to connect and install with equipment having a flange connection structure. When the equipment to be installed has a flange interface, simply install the flange docking seat 12 on the base mounting base 7 via the connecting screw 11, then connect the flange of the equipment to the flange seat on the flange docking seat 12 and secure it with bolts. This connection method is stable and reliable, can withstand large loads, and facilitates the installation and disassembly of the equipment, further improving the applicability and convenience of the device. At the same time, the flange docking seat 12 can also be replaced with different specifications and sizes according to actual needs to meet the connection requirements of different equipment.

[0029] In this embodiment, preferably, the length of the fixed top beam 5 is greater than the width of the frame through hole 2, and rubber pads 13 are fixedly connected to the inner walls on both sides of the frame through hole 2. The design that the fixed top beam 5 is longer than the width of the frame through hole 2 allows it to span the frame through hole 2 after installation, providing a more stable support structure for the entire device and enhancing its overall strength and stability. The rubber pads 13 fixedly connected to the inner walls on both sides of the frame through hole 2 serve as buffers and shock absorbers. When the device is subjected to vibration or impact during operation, the rubber pads 13 can absorb some energy, reducing damage to the device structure and extending its service life. Simultaneously, the rubber pads 13 can effectively reduce noise generated during device operation, providing operators with a quieter and more comfortable working environment. Furthermore, the rubber pads 13 have a certain degree of elasticity, which can compensate for minor errors during manufacturing and installation to a certain extent, ensuring a tighter fit between the fixed top beam 5 and the main frame 1 of the bracket, further improving the stability and reliability of the device.
