Description

Technical Field

[0001] This utility model relates to the field of tractor parts technology, and in particular to a tractor suspension limiting device. Background Technology

[0002] In agricultural production, the stability and ease of adjustment of the tractor suspension system are crucial to the efficiency of agricultural implement operations, and its rational design directly affects the installation efficiency and performance of the equipment. Existing technologies already include improved solutions for tractor suspension limiting mechanisms. For example, Chinese utility model patent CN216626571U discloses a technical solution for limiting the suspension plate through the cooperation of an adjuster and an adjusting screw. This suspension plate limiting mechanism includes: two adjusters, each fixedly mounted on a suspension plate; each adjuster is hinged to the bottom of a screw adjusting seat, and the adjuster is used to adjust the tilt angle of the screw adjusting seat; the tops of the screw adjusting seats in the two adjusters are aligned, and the two screw adjusting seats are connected by an adjusting screw; in this solution, the adjuster fixes the angle of the screw adjusting seat through the cooperation of an adjusting bolt and a lug, and the two adjusters are connected by an adjusting screw to achieve rigid limiting.

[0003] However, this technical solution has the following drawbacks: limited angle adjustment: the adjusting bolt passes through the through hole of the lug, and the lug is rigidly connected to the lead screw adjusting seat. This rigid connection means that the adjusting lead screw cannot swing relative to the adjuster, that is, it cannot adjust the angle according to the actual installation environment. When there is a deviation in the installation position or angle of the tractor suspension plate, the adjusting lead screw cannot adjust adaptively, which seriously affects the installation adaptability.

[0004] Therefore, how to design a tractor suspension limiting device that can achieve both rigid limiting of the suspension mechanism and allow for angle adjustment of the lead screw, so as to reduce installation difficulty and improve equipment versatility, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] This utility model proposes a tractor suspension limiting device, which solves the problems of limited angle adjustment and difficult installation in the prior art.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A tractor suspension limiting device includes two hinge folders connected by a spacing adjustment assembly. Each hinge folder includes a first hinge seat and a second hinge seat, hinged together. A mounting plate is fixedly connected to the first hinge seat, and the second hinge seat is connected to the spacing adjustment assembly. A first locking member is rotatably connected to the first hinge seat, and a second locking member is rotatably connected to the second hinge seat. The first and second locking members are connected by locking bolts. The first and second hinge seats can rotate relative to each other, allowing for flexible adjustment of their relative angle. The distance between the two hinge folders is adjusted using the spacing adjustment assembly. After the angle is adjusted, the relative positions of the first and second hinge seats are fixed.

[0008] Both the first and second locking components include locking nuts, which are connected by locking bolts. When the locking bolts are connected to the locking nuts of both the first and second locking components, the distance between the two locking nuts can be fixed, thereby fixing the relative angle between the first and second hinge seats and ensuring the stability of the hinge folding device during use.

[0009] The first and second locking components also include threaded posts. The first and second hinge seats have through holes. The upper end of the threaded post is fixedly connected to a locking nut, and the threaded post passes through the through hole to connect with a limiting nut. The diameter of the through hole is smaller than the diameter of the locking nut to prevent the locking nut from passing through the through hole and to ensure a stable connection between the first or second locking component and the hinge seat.

[0010] The spacing adjustment assembly includes a turnbuckle nut, and an adjusting bolt is connected to the second hinge seat. The adjusting bolt is threadedly connected to the turnbuckle nut. By rotating the turnbuckle nut, the lengths of the two adjusting bolts extending into the turnbuckle nut can be adjusted, thereby adjusting the distance between the two hinge folders to adapt to the spacing requirements between the suspension plates of different tractors.

[0011] One end of the adjusting bolt is welded to the second hinge seat. This ensures the stability of the connection between the two adjusting bolts and the second hinge seat.

[0012] A locking nut is connected to the adjusting bolt, and the locking nut engages with the end of the turnbuckle. After the spacing is adjusted, tightening the locking nut prevents the turnbuckle from loosening and ensures the stability of the spacing.

[0013] The mounting plate is equipped with mounting bolts, and the mounting bolts and the first hinge seat are located on both sides of the mounting plate. The mounting bolts are used to fix the mounting plate to the tractor suspension plate.

[0014] One end of the mounting bolt is welded to the first hinge seat to enhance the connection strength between the mounting plate and the first hinge seat.

[0015] The first hinge seat and the second hinge seat are hinged together by a pin.

[0016] The beneficial effects of this utility model are as follows: by setting the hinged connection between the first hinge seat and the second hinge seat, the spacing adjustment component can swing relative to the mounting plate. Furthermore, during device installation, the locking bolt is only connected to the first locking member, and the locking bolt is not connected to the second locking member. This effectively avoids interference during installation, achieves flexible angle adjustment, effectively solves the installation difficulty problem caused by the inability of the adjusting screw to swing relative to the adjuster in the prior art, and improves the installation adaptability of the device.

[0017] The first and second locking components are connected by locking bolts, which can be quickly locked after the angle adjustment is completed. The operation is simple, ensuring both the flexibility of angle adjustment and the stability during operation.

[0018] The spacing adjustment assembly uses a turnbuckle nut and adjusting bolt to easily adjust the distance between the two hinge folders, adapting to the spacing requirements of suspension plates of different tractor models and improving the versatility of the device.

[0019] The connections between the components are secure, such as the welded connection between the adjusting bolt and the second hinge seat, and the welded connection between the mounting bolt and the first hinge seat, ensuring the structural strength and reliability of the device during operation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1, as Figure 1 , Figure 2 As shown, a tractor suspension limiting device includes two hinge folders 2 connected by a spacing adjustment assembly. Each hinge folder 2 includes a first hinge seat 21 and a second hinge seat 22, hinged together. A mounting plate 1 is fixedly connected to the first hinge seat 21, and the second hinge seat 22 is connected to the spacing adjustment assembly. A first locking element 3 is rotatably connected to the first hinge seat 21, and a second locking element 4 is rotatably connected to the second hinge seat 22. The first locking element 3 and the second locking element 4 are connected by a locking bolt 5. The suspension limiting device is mounted between the two suspension plates of the tractor to achieve a rigid connection and fixed position of the two suspension plates. The first hinge seat 21 and the second hinge seat 22 are hinged together by a pin, allowing relative rotation and flexible adjustment of their relative angle. The hinge folders 2 allow for the swing angle of the spacing adjustment assembly relative to the mounting plate 1.

[0026] Specifically, during device installation, the locking bolt 5 is only connected to the first locking member 3, and the locking bolt 5 is not connected to the second locking member 4. After the mounting plate 1 is installed and the distance adjustment component is adjusted, the second locking member 4 is rotated to connect the locking bolt 5 to the second locking member 4, effectively avoiding interference during installation.

[0027] Furthermore, both the first locking member 3 and the second locking member 4 include locking nuts, which are connected by locking bolts 5. When the locking bolts 5 are connected to the locking nuts of both the first locking member 3 and the second locking member 4, the distance between the two locking nuts can be fixed, thereby fixing the relative angle between the first hinge seat 21 and the second hinge seat 22, ensuring the stability of the hinge folding device 2 during use.

[0028] Furthermore, the first locking member 3 and the second locking member 4 also include threaded posts. The first hinge seat 21 and the second hinge seat 22 are provided with through holes. The upper end of the threaded post is fixedly connected to the locking nut, and the threaded post passes through the through hole to connect with the limiting nut. The diameter of the through hole is smaller than the diameter of the locking nut to prevent the locking nut from passing through the through hole and to ensure a stable connection between the first locking member 3 or the second locking member 4 and the hinge seat.

[0029] Example 2, based on Example 1, provides a tractor suspension limiting device. The spacing adjustment component includes a turnbuckle nut 7, and an adjusting bolt 6 is connected to the second hinge seat 22. The adjusting bolt 6 is threadedly connected to the turnbuckle nut 7. The threads at both ends of the turnbuckle nut 7 are opposite in direction, respectively adapting to the adjusting bolts 6 on both sides. By rotating the turnbuckle nut 7, the length of the two adjusting bolts 6 extending into the turnbuckle nut 7 can be adjusted, thereby adjusting the distance between the two hinge folders 2 to adapt to the spacing requirements between different tractor suspension plates.

[0030] Furthermore, one end of the adjusting bolt 6 is welded to the second hinge seat 22. This ensures the stability of the connection between the two adjusting bolts 6 and the second hinge seat 22.

[0031] Furthermore, a locking nut is connected to the adjusting bolt 6, and the locking nut engages with the end of the turnbuckle nut 7. After the spacing is adjusted, tightening the locking nut prevents the turnbuckle nut from loosening and ensures the stability of the spacing.

[0032] Furthermore, mounting plate 1 is provided with mounting bolts 11, and mounting bolts 11 and the first hinge seat 21 are located on opposite sides of mounting plate 1. Specifically, mounting plate 1 is a rectangular metal plate used to fix the device to the suspension plate 8 of the tractor, and one end of the mounting bolt 11 is welded to the first hinge seat 21. This ensures the stability of the overall structure of the device installation.

[0033] Installation process of suspension limit device:

[0034] 1. Connect the mounting plate 1 on the left side of the suspension limit device to the preset mounting position on the suspension pull plate 8 of the tractor. Use the mounting bolts 11 to pass through the mounting holes on the suspension pull plate 8 and tighten the mounting nuts 11 to fix the left mounting plate 1.

[0035] 2. Adjust the angle of the two hinge folders 2, and adjust the distance between the two hinge folders 2 through the spacing adjustment component. Rotate the basket nut 7 to adjust the distance between the two hinge folders 2 so that the mounting plate 1 on the right side is connected to the preset installation position on the suspension plate 8. Fix the mounting plate 1 on the right side with the mounting bolt 11.

[0036] 3. After the two mounting plates 1 are fixed, tighten the locking nut on the adjusting bolt 6 so that it abuts against the end of the turnbuckle nut 7 to prevent the turnbuckle nut 7 from loosening;

[0037] 4. Pass the locking bolt 5 through the locking nuts of the first locking member 3 and the second locking member 4 to fix the distance between the two locking nuts, thereby fixing the first hinge seat 21 and the second hinge seat 22 and completing the angle locking; the suspension limit device is now installed.
