Description

Technical Field

[0001] The utility model relates to the technical field of McReel suspension systems, in particular to a detachable McReel independent suspension system. Background Art

[0002] Traditional mechanical suspension systems, particularly leaf spring suspension or hydraulic suspension systems, are commonly used on equipment such as tractors and combine harvesters to provide wheel support and shock absorption. However, these existing technical solutions have some significant drawbacks:

[0003] 1. Agricultural machinery, such as tractors and combine harvesters, often operate on irregular and rugged terrain. Traditional suspension systems have poor adaptability to complex terrain and cannot effectively cope with the ups and downs of different surfaces. This causes excessive vibration during operation, affecting operational stability and comfort.

[0004] 2. During farmland operations, equipment may be exposed to severe ground impacts (such as vibrations during plowing or sowing). Traditional suspension systems often lack independence, leading to significant mutual interference between wheels, resulting in uneven load distribution and affecting maximization of traction.

[0005] 3. In farmland operations, the rapid repair and replacement of equipment is crucial, especially during the harvest season. Any prolonged downtime may cause huge economic losses. Existing suspension systems are generally non-detachable and cannot be flexibly adjusted according to operational needs, which limits the versatility and adaptability of agricultural machinery.

[0029] The position terms such as "up, down, left, right, front, back, etc." in this utility model are relative to Figure 1 The positional relationship shown.

[0030] like Figure 1 and 6 As shown, a detachable McReel 22 independent suspension system includes a center base plate 1, with detachable suspension assemblies disposed on both the front and rear sides of the center base plate 1. The suspension assembly includes two upper suspension plates 2, with multiple copper columns disposed between the two upper suspension plates 2 for support. The two upper suspension plates 2 are fixedly connected by bolts. The upper suspension plates 2 include a middle plate 3, with upwardly inclined upper support plates 4 disposed on both the left and right ends of the middle plate 3. The middle plate 3 and the upper support plates 4 are an integral structure. A connecting block 5 is disposed between the two middle plates 3, and a limit plate 6 is disposed on the side of the middle plate 3 away from the connecting block 5. The connecting block 5, the middle plate 3, and the limit plate 6 are fixedly connected by bolts. The upper end of the limit plate 6 is higher than the middle plate 3. A locking hole 7 is provided on the center base plate 1 at the position corresponding to the limit plate 6. The upper end of the limit plate 6 is positioned within the locking hole 7 to facilitate rapid positioning of the suspension assembly and the center base plate 1. The connecting block 5 and the center base plate 1 are fixedly connected by bolts.

[0031] like Figure 2 、 4 As shown in Figure 6, wheel posts 8 are fixed to the middle plate 3 at both ends of the limit plate 6. The wheel posts 8 are rotatably connected to one end of the suspension plate 27 via flange bearings. A retaining spring is mounted on the wheel post 8 outside the flange bearing. The retaining spring and the wheel post 8 ensure the swing reliability of the entire suspension. Arc-shaped slots 9 are provided on both ends of the limit plate 6. A lower limit block 10 is fixed to the limit plate 6 below the arc-shaped slots 9. An upper limit slot 11 is provided on the limit plate 6 above. The lower limit block 10 and the limit plate 6 are integrally structured. The suspension plate 27 is provided with an arc-shaped protrusion 12, and the arc-shaped protrusion 12 is placed in the arc-shaped groove 9 and rotates along the arc-shaped groove 9. The suspension plate 27 on the upper side of the arc-shaped protrusion 12 is provided with an upper limit block 13 that cooperates with the upper limit groove 11, and the lower side of the suspension plate 27 is provided with a lower limit groove 14 that cooperates with the lower limit block 10. The upper limit block 13 and the suspension plate 27 are an integral structure. The upper limit groove 11 and the upper limit block 13 cooperate to limit the angle range of the suspension plate 27 to rotate upward, and the lower limit block 10 and the lower limit groove 14 cooperate to limit the angle range of the suspension plate 27 to rotate downward.

[0032] like Figure 1 、 3As shown in Figure 5, the other end of the suspension plate 27 is detachably connected to a connecting assembly. The connecting assembly includes a connecting tube 15, on which a flange 16 is fixed, which is bolted to the suspension plate 27. Each suspension plate 27 corresponds to two flanges 16 (a group). The end of the suspension plate 27 is placed between the two flanges 16, and then the flange 16 is bolted to the suspension plate 27. The connecting tube 15 includes a first cylinder 17 and a second cylinder 18 arranged coaxially. The first cylinder 17 and the second cylinder 18 are fixed by flange bolts. The first cylinder 17 is connected to the motor 19. A deep groove ball bearing 20 is fixed in the second cylinder 18. The deep groove ball bearing 20 is connected to a connecting piece 21. The connecting piece 21 is detachably connected to the fixing plate 26 of the wheat wheel 22 by bolts. The output end of the motor 19 passes through the connecting assembly (i.e., through the first cylinder 17 and the second cylinder 18) and is fixedly connected to the connecting piece 21 by a tightening sleeve 23. The wheat wheel is driven to rotate by the motor 19.

[0033] like Figure 1 and 6 As shown, a shock absorber 24 is disposed between one end of the suspension plate 27, closest to the connecting assembly, and the upper end of the suspension upper plate 2. The upper end of the shock absorber 24 is hingedly connected to the upper end of the upper support plate 4. Specifically, the upper end of the shock absorber 24 is placed between the two upper support plates 4 and then hingedly connected to the upper support plate 4 via a plug bolt. The plug bolts on both sides of the upper end of the shock absorber 24 are fitted with spacer columns 25. The lower end of the shock absorber 24 is hingedly connected to one end of the fixing plate 26. Specifically, the lower end of the shock absorber 24 is placed between the two fixing plates 26 and then connected via a plug bolt. The plug bolts on both sides of the lower end of the shock absorber 24 are fitted with spacer columns 25. The other end of the fixing plate 26 is fixedly connected to the suspension plate 27.

[0034] When passing through a bumpy road section, the suspension plate 27 rotates along the wheel column 8, and when the suspension plate 27 rotates to a certain angle, it will contact the limit plate 6 to achieve mechanical limitation. When the suspension plate 27 rotates, it will drive the shock absorber 24 to compress to achieve the shock absorption function. The spring of the shock absorber 24 realizes the reaction force to press the wheat wheel on the ground to achieve the stability of the entire chassis during driving.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
