[0012] Furthermore, a hub for connecting with a drive axle is provided on the inner wall of the wheel body.

[0013] Furthermore, reinforcing steel rings are also provided on the inner walls at both ends of the wheel body.

[0014] Furthermore, the wheel body includes several V-shaped plates and two fixing rings. The several V-shaped plates are evenly distributed between the two fixing rings, and both ends of each V-shaped plate are respectively fixedly connected to the two fixing rings. The top of the V-shaped plate protrudes from the outer wall surface of the fixing ring. An avoidance groove for avoiding the connecting ring is provided on the outer wall of the fixing ring. The fixing holes are located between the lower parts of two adjacent V-shaped plates.

[0015] Furthermore, the inner wall of the connecting ring is in contact with the top of the V-shaped plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following further describes the present utility model with reference to specific embodiments in the drawings.

[0029] Refer to Figures 1-6, a novel tillage wheel of the present utility model includes a wheel body 1 and a support ring 2. A connecting ring 3 is provided on the inner wall of the support ring 2. At least two connecting holes 11 are evenly distributed on the connecting ring 3. A fixing ring 102 is provided on the wheel body 1. At least two fixing holes 4 are evenly distributed on the fixing ring 102. The support ring 2 is sleeved on the periphery of the wheel body 1. Specifically, the support ring 2 is sleeved along the axial direction of the wheel body 1, and the connecting ring 3 is attached to one side of the fixing ring 102 to form a superimposed structure. The connecting ring 3 and the fixing ring 102 are detachably connected, which is convenient for disassembly and assembly.

[0030] For the tillage wheel of the present utility model, the support ring 2 is axially superimposed and connected by the connecting ring 3 and the fixing ring 102. Compared with the circumferential bolt fastening method in the prior art, the connection point is hidden inside the wheel body and will not contact the ground. Without the influence of friction at the connection point, the connection reliability of the support ring 2 can be effectively improved, the risk of loosening of the support ring 2 is greatly reduced, and its service life is extended.

[0031] At the same time, the support ring 2 is detachably connected by the connecting ring 3 and the fixing ring 102. During disassembly and assembly, by loosening the fastener between the connecting ring 3 and the fixing ring 102, the support ring 2 can be axially removed from one side of the wheel body 1. On the premise of ensuring the tillage performance of the tillage wheel, the disassembly and assembly of the support ring are made simpler and faster.

[0032] Preferably, the support ring 2 is made of rubber material. The rubber support ring 2 makes the tillage wheel in flexible contact with the ground when walking, greatly reducing noise and vibration. A steel ring 5 is provided on the inner wall of the support ring 2 to improve the rigid strength of the support ring 2 and also facilitate the fixing of the connecting ring 3 on the support ring 2. The connecting holes 11 are evenly opened on the inner wall of the connecting ring 3, so that the support ring 2 is more evenly stressed when fixed. Further, the support ring 2, the connecting ring 3, and the steel ring 5 are all closed circular rings. The closed circular ring structure can further improve the structural strength of the support ring 2 and thus extend its service life. Furthermore, the cross-section of the support ring 2 is rectangular or oval, which can increase the contact area between the support ring 2 and the ground, making the tillage wheel more stable when walking. And a plurality of cross-set patterns are provided on the outer wall surface of the support ring 2 to increase the friction between the support ring 2 and the ground, thereby improving the walking stability and braking performance.

[0033] Preferably, the support ring 2 is located at the axial middle position of the wheel body 1. Setting the support ring 2 at the axial middle position of the wheel body 2 enables the force application point to be at the middle position when the tillage wheel is moving, improving the walking stability of the tillage wheel. The connecting ring 3 and the fixing ring 102 are fixedly connected by matching the bolt 6 and the nut 7. Specifically, the bolt 6 passes through the connecting hole 11 and the fixing hole 4 in sequence and is connected to the nut 7 to achieve fixed connection. The cooperation and fixation method of the bolt 6 and the nut 7 meets the requirement of detachable installation and has better connection reliability. In other embodiments, the connecting ring 3 and the fixing ring 102 can also be connected by a pin.

[0034] Preferably, a hub 9 for connecting with the drive axle 8 is provided on the inner wall of the wheel body 1. The outer edge of the hub 9 and the inner wall of the wheel body 1 can be fixed by welding, and the hub 9 and the drive axle 8 can be connected by fastening bolts, facilitating disassembly, installation and maintenance while installing the tillage wheel on the drive axle 8.

[0035] Preferably, the hub 9 is located at the axial middle position of the wheel body 1, and reinforcing steel rings 10 are further provided on the inner walls at both ends of the wheel body 1, which can further reinforce the structural strength of the tillage wheel and prevent the tillage wheel from deforming.

[0036] Preferably, the wheel body 1 in this embodiment includes a plurality of V-shaped plates 101 and two fixing rings 102. Among them, the plurality of V-shaped plates 101 are evenly distributed between the two fixing rings 102, and both ends of each V-shaped plate 101 are fixedly connected to the two fixing rings 102 respectively to form a wheel frame to realize the tillage function of the tillage wheel; the top of the V-shaped plate 101 protrudes from the outer wall surface of the fixing ring 102 to ensure that the V-shaped plate 101 can press down or cut off sundries such as straw. An avoidance groove 103 for avoiding the connecting ring 3 is provided on the outer wall of the fixing ring 102 to avoid the problem of interference between the connecting ring 3 and the fixing ring 102 when the support ring 2 is disassembled and assembled. The fixing hole 4 is located between the lower parts of two adjacent V-shaped plates 101 to hide the connection point inside the wheel body 1.

[0037] Preferably, the inner wall of the connecting ring 3 is in contact with the top of the V-shaped plate 101, so that most of the force application points of the support ring 2 are concentrated at the contact position between the support ring and the V-shaped plate 101, avoiding the tangential force of the connecting ring 3 acting on the bolt 6 and further improving the connection reliability. The inner wall surface of the connecting ring 3 is a wavy surface. After the connecting ring 3 is installed, the corresponding wave grooves of the connecting ring 3 are stuck on the V-shaped plate 101 to prevent the connecting ring 3 from rotating circumferentially and further reducing the tangential stress of the bolt 6; correspondingly, the outer wall surface of the fixing ring 102 is also a wavy surface, which can avoid the wave protrusions of the connecting ring 3 to ensure that the connecting ring 3 can be installed in place.

[0038] Preferably, the tillage wheel in this embodiment is formed by splicing at least two wheel bodies 1, and the corresponding fixing rings 102 of two adjacent wheel bodies 1 are detachably connected. Specifically, the corresponding fixing rings 102 of two adjacent wheel bodies 1 can be fixedly connected by fastening bolts. The tillage wheel formed by splicing multiple wheel bodies 1 can effectively increase the tillage area of the tillage wheel, and the detachable connection method between multiple wheel bodies 1 facilitates the user to assemble and use according to actual needs, which is very convenient. It should be noted that for the tillage wheel formed by splicing multiple wheel bodies, the fixing holes 4 are opened on the corresponding fixing rings 102 of two adjacent wheel bodies 1, as long as the installation requirements are met.

[0039] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicality of the patent.
