Description

Technical Field

[0001] This utility model relates to agricultural machinery, specifically to a walking structure for use with agricultural implements. Background Technology

[0002] Currently, the component suitable for connecting the walking wheels on most agricultural machinery is the crossbeam. Existing walking wheels and crossbeams are mostly directly connected by bolts, and the structural strength is greatly affected by the bolts. The connection method needs to be improved. Since agricultural machinery is mostly used in rugged and uneven farmland terrain, the walking structure, after being installed on the agricultural machinery, also needs to have the ability to adapt to the terrain. Moreover, in order to improve the accuracy of sowing, fertilizing, etc., in addition to preventing the walking wheels from spinning and slipping, it is also necessary to measure the speed of the walking wheels and adjust the speed of sowing and fertilizing according to the walking speed of the walking mechanism.

[0003] To meet the above requirements, this utility model provides a walking structure that is easy to connect securely with the cross beam, whose height can be adaptively adjusted to the terrain, and which can accurately measure speed. Utility Model Content

[0018] 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. Example

[0019] Figures 1-4 As shown, a walking structure for agricultural implements includes a mounting mechanism, a support arm 1, a bearing assembly, and walking wheels 2. The mounting mechanism is used to connect the walking structure of this embodiment to the cross beam of the agricultural implement. The mounting mechanism includes a mounting base 3, fasteners 4, and connectors. The mounting base 3 is provided with a mounting slot. The fasteners 4 are disposed in the mounting slot and are detachably connected to the mounting base 3 by bolts or other structures. The fasteners 4 are provided with a fastening end face, and a machine clamping gap is formed between the fastening end face and one side wall of the mounting slot. When connecting the mounting base 3 to the cross beam of the agricultural implement, the mounting base 3 is placed on the cross beam and the cross beam is positioned in the mounting slot corresponding to the machine clamping gap. The fasteners 4 are then connected to the mounting base 3. By utilizing the fastening end face of the fasteners 4 and the groove wall of the mounting slot, the cross beam is clamped, thereby realizing the connection between the mounting base 3 and the cross beam.

[0020] Please see Figures 1-3To improve the connection strength with the X-beam, the fastening end face is an inclined surface sloping towards the bottom of the mounting slot. After the fastener 4 is connected to the mounting base 3, the X-beam abuts against the inclined fastening end face, preventing the X-beam from sliding out of the clamping gap of the machine. A pad can also be set on the fastening end face to prevent direct contact between the fastener 4 and the X-beam, which would cause wear. Furthermore, the groove wall of the mounting slot facing the fastening end face is also set as an inclined surface sloping towards the bottom of the mounting slot, and the clamping gap of the machine is narrowed, further improving the connection strength between the mounting mechanism and the X-beam.

[0021] In this embodiment, the existing method of directly connecting the mounting base 3 and the cross beam with bolts is changed to a method in which the mounting base 3 and the fastener 4 work together to hold the cross beam. This avoids concentrating the force of the walking structure on the connecting bolts, optimizes the connection method, and improves the structural strength and stability of the equipment.

[0022] The other end face of the fastener 4, opposite to the fastening end face, abuts against the other side of the mounting slot wall, preventing the fastener 4 from directly bearing a large load and deforming. Furthermore, a limiting groove 15 is provided on the end face of the fastener 4 facing away from the fastening end face, and a limiting inclined plate 14 is provided on the slot wall of the mounting slot facing away from the fastening end face. The limiting inclined plate 14 is inclined towards the opening of the mounting slot. When the fastener 4 is connected to the mounting base 3, the limiting inclined plate 14 is embedded in the limiting groove 15 and abuts against the limiting groove 15. This abutting cooperation between the limiting inclined plate 14 and the limiting groove 15 not only supports the fastener 4 but also prevents relative displacement between the fastener 4 and the mounting component, thus affecting the connection stability between the mounting mechanism and the cross beam.

[0023] The connector includes a connecting plate 5, which is connected to the mounting base 3. Preferably, the connecting plate 5 and the mounting slot are located on opposite end faces of the mounting base 3. The connecting plate 5 is vertically arranged, and one end of the support arm 1 is connected to the connecting plate 5 via a connecting pin, a connecting bearing, or other structure. The support arm 1 can rotate up and down relative to the connection point with the connecting plate 5. The connecting plate 5 is provided with an upper limit part 6 and a lower limit part 7, which are used to limit the range of vertical rotation of the support arm 1.

[0024] Please see Figure 3 The lower limiting part 7 is a fixed limiting block, limiting protrusion, or other structure, while the upper limiting part 6 is a limiting pin. At least two limiting holes 8 are provided circumferentially around the connection point between the support arm 1 and the connecting plate 5, and the limiting pin can pass through either limiting hole 8. Furthermore, there are two connecting plates 5, each reinforced with a reinforcing rib plate. The support arm 1 is positioned between and connected to both connecting plates 5. The lower limiting part 7 is connected to both connecting plates 5, and the limiting pin passes through the corresponding limiting pin holes of the two connecting plates 5.

[0025] Please see Figure 1 , Figure 2 and Figure 4 The bearing assembly includes a support shaft 9, a hub bearing, and an encoder 10. The support shaft 9 is connected to the support arm 1. The hub bearing is mounted on the support shaft 9. The hub bearing includes a bearing housing 11, bearing components 12, and a bearing end cover 13. The bearing components 12 are housed inside the bearing housing 11. The support shaft 9 passes through the interior of the bearing housing 11 and is connected to the bearing housing 11 through the bearing components 12. Through the bearing components 12, the bearing housing 11 can rotate relative to the support shaft 9. The traveling wheel 2 is connected to the bearing housing 11 of the hub bearing and rotates synchronously with the bearing housing 11. The encoder 10 is a rotary speed measuring encoder structure in the form of an encoder disc, etc. The encoder 10 is connected to the bearing housing 11 and is encapsulated inside the bearing housing 11 through the bearing end cover 13. The rotation of the bearing housing 11 will drive the encoder 10 to rotate, thereby the encoder 10 can be used to measure the rotational speed of the traveling wheel 2.

[0026] While the support arm 1 rotates up and down relative to the mounting mechanism, it can drive the walking wheel 2 to adjust up and down, so that the walking wheel 2 can always keep its feet on the ground. In addition, with the encoder 10, the rotation speed of the walking wheel 2 can be measured and monitored. Depending on the terrain, the height of the walking wheel 2 can be limited by adjusting the position of the upper limit device.

[0027] Similar to the bearing assembly structure in the prior art, in the bearing assembly of this embodiment, the inner ring of each bearing is connected to the support shaft 9, and the outer ring of each bearing is connected to the bearing housing 11. The area on the support shaft 9 corresponding to the inside of the bearing housing 11 is equipped with annular gaskets, locking nuts and other structures to axially fix the bearing assembly on the support shaft 9. The bearing housing 11 is also provided with skeleton oil seals, embedded transparent covers and other structures on both sides of the bearing to seal the bearing and prevent penetration. The bearing end cap 13 is located at the end of the bearing housing 11 away from the support arm 1 and is used to seal and prevent dust.
