Description

An anti-entanglement ring and a structure using the anti-entanglement ring Technical Field

[0001] The present application relates to the technical field of mechanical devices, and in particular to an anti-entanglement ring and a structure using the anti-entanglement ring. Background Art

[0002] In mechanical operating equipment such as harvesters, weeders, and threshers, blades or gears are densely distributed on the shaft tube of the movable blade holder. By driving the shaft tube of the movable blade holder to rotate, the blades or gears are driven to rotate around the axis with a large radius. The rapidly rotating blades or gears contact weeds or crops, thereby cutting the weeds or separating the crop grains from the crop straw.

[0003] In the prior art, combine harvesters, as integrated automated equipment for harvesting, threshing and straw chopping, have been increasingly widely used. In conventional combine harvester structures, after the movable blade seat shaft tube is welded to the frame, there is a certain gap, large or small, between the left and right ends of the movable blade seat shaft tube and the side walls of the frame. During the high-speed rotation of the movable blade seat shaft tube, grass or straw is easily entangled on the driving shaft and jammed on the left and right rotating bearings, making the movable blade seat shaft tube unable to rotate and work, requiring manual elimination, which is time-consuming and labor-intensive, affecting work efficiency and equipment service life.

[0004] Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present application is to overcome the gap between the drive shaft and its driving components in the prior art, which easily causes entanglement and jamming, affecting the normal operation and service life of the equipment.

[0006] To this end, the present application proposes an anti-entanglement ring, comprising:

[0007] At least two ring plates, each of which is in an arc-shaped structure; all the ring plates are connected end to end to form a circular isolation area;

[0008] At least two clamping plates are fixed on one of the two connected ring plates, and a slot is formed between the clamping plates and the ring plate; the other ring plate is suitable for being inserted and fixed in the slot.

[0009] Any of the ring plates includes a bottom plate and a side plate; the bottom plate is a flat plate bent in an arc shape; the side plates are curved plates arranged along the outer edge of the bottom plate.

[0010] The clamping plate is welded and fixed on the outer wall surface of the side plate.

[0011] The side panels are arranged perpendicular to the bottom panel.

[0012] The adjacent bottom plates are bolted and fixed.

[0013] Also includes:

[0014] At least one obstacle removal opening is provided on any of the base plates.

[0015] The obstacle removal opening is an obstacle removal groove formed by concavely forming the inner circle edge of the arc-shaped bottom plate toward the outer circle edge.

[0016] The width of the slot opening of the obstacle clearing slot is greater than the width of the slot bottom.

[0017] A plurality of assembly holes are provided on the bottom plate and / or the side plate, and are suitable for installing the anti-entanglement ring through the assembly holes.

[0018] The present application provides a structure using an anti-entanglement ring, comprising the anti-entanglement ring described above, wherein the anti-entanglement ring is sleeved and fixed on a bearing seat.

[0019] The technical solution of this application has the following advantages:

[0020] 1. The anti-entanglement ring provided in this application comprises at least two ring plates and at least two clamping plates. The ring plates are each arc-shaped, and all the ring plates are connected end to end to form a circular isolation zone. At least two clamping plates are fixed to one of the two connected ring plates, forming a slot between the ring plates; the other ring plate is adapted to be inserted and fixed in the slot. The circular isolation zone formed by the ring plates is suitable for being fixed on the drive shaft and blocking the gap to prevent weeds or straw from entangled on the drive shaft.

[0028] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0029] Example 1

[0030] This embodiment provides an anti-entanglement ring, as shown in Figure 1, comprising at least two ring plates 1k and at least two clamping plates 2k. The ring plates 1k are each arc-shaped, and all the ring plates 1k are connected end-to-end to form a circular isolation zone. At least two clamping plates 2k are fixed to one of the two connected ring plates 1k, forming a slot 3k between the ring plate 1k and the other ring plate 1k; the other ring plate 1k is adapted to be inserted and fixed in the slot 3k.

[0031] In this embodiment, as shown in Figure 1, any ring plate 1k includes a bottom plate 11k and a side plate 12k. The bottom plate 11k is a flat plate bent in an arc shape, and the side plate 12k is a curved plate arranged along the outer ring edge of the bottom plate 11k. In this embodiment, the bottom plate 11k and the side plate 12k are integrally formed.

[0032] In this embodiment, two ring plates 1k are provided, each shaped like a semicircular arc. The outer wall of one ring plate 1k fits against the inner wall of the other ring plate 1k. Holes are punched through the two stacked base plates 11k, allowing the two ring plates 1k to be bolted together. The base plates 11k also have several mounting holes 5k sized for conventional bolts, allowing bolts to pass through these holes to secure the anti-entanglement ring to other equipment. Alternatively, three or four ring plates 1k can be provided, connected end-to-end in sequence to form a circular isolation zone. The specific number of ring plates 1k depends on the specific situation.

[0033] In this embodiment, the side plate 12k of any ring plate 1k is arranged perpendicular to the bottom plate 11k, the card plate 2k is bent in an L shape, the short side of the L shape is welded and fixed to the outer wall surface of one side plate 12k, and is located at both ends of the side plate 12k, the long side of the L shape is arranged parallel to the side plate 12k, and a slot 3k is formed between the card plate 2k and the side plate 12k, and the two ends of the other side plate 12k are correspondingly inserted into the slot 3k.

[0034] As shown in Figure 1, the base plate 11k also features at least one clearing opening for observation or access to other equipment. In this embodiment, the clearing opening is a clearing slot 4k formed by recessing the inner edge of the arc-shaped base plate 11k toward the outer edge. The clearing slot 4k is an isosceles trapezoidal shape, with the opening wider than the bottom. The slot is located on the inner ring of the base plate 11k. The anti-entanglement ring of the base plate 11k forms a hole for securement on the bearing seat. Therefore, the slot engages the surface of the bearing seat. The large size of the slot facilitates internal observation. In this embodiment, two clearing slots 4k are provided on the base plate 11k of each ring plate 1k, with four clearing slots 4k evenly spaced around the circumference.

[0035] The ring plate 1k forms a circular isolation area, which is suitable for being fixed on the driving shaft and blocked in the gap to prevent weeds or straw from being entangled on the driving shaft.

[0036] Example 2

[0037] This embodiment provides a structure using an anti-entanglement ring, including the anti-entanglement ring in Example 1, and the anti-entanglement ring is sleeved and fixed on the bearing seat.

[0038] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this application.
