Description

Technical Field

[0001] The invention 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 seat. By driving the shaft tube of the movable blade seat 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 off the weeds or separating the crop grains from the crop stalks.

[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, and manual elimination is required, which is time-consuming and labor-intensive, affecting work efficiency and equipment service life. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the gap between the drive shaft and its driving components in the prior art, which is prone to entanglement and jamming, affecting the normal operation and service life of the equipment.

[0005] To this end, the present invention proposes an anti-entanglement ring, comprising:

[0006] At least two ring plates are respectively in an arc-shaped structure; all the ring plates are connected end to end to form a circular isolation area;

[0007] 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.

[0008] Any of the ring plates comprises a bottom plate and a side plate; the bottom plate is a flat plate bent in an arc shape; the side plate is a curved plate arranged along the outer edge of the bottom plate.

[0009] The clamping plate is welded and fixed on the outer wall surface of the side plate.

[0010] The side plate is arranged perpendicular to the bottom plate.

[0011] The adjacent bottom plates are bolted and fixed.

[0012] Also includes:

[0013] At least one obstacle removal opening is provided on any of the base plates.

[0014] 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.

[0015] The width of the slot opening of the obstacle removal slot is greater than the width of the slot bottom.

[0016] A plurality of assembly holes are arranged on the bottom plate and / or the side plate, and are suitable for installing the anti-entanglement ring through the assembly holes.

[0017] The present invention 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.

[0018] The technical solution of the present invention has the following advantages:

[0019] 1. The anti-entanglement ring provided by the present invention comprises at least two ring plates and at least two clamping plates. The ring plates are respectively in an arc-shaped structure, and all the ring plates are connected end to end to form a circular isolation zone.

[0028] Example 1

[0029] This embodiment provides an anti-entanglement ring, such as Figure 1 As shown, it includes at least two ring plates 1k and at least two clamping plates 2k. The ring plates 1k are respectively in an arc-shaped structure, and all the ring plates 1k are connected end to end to form a circular isolation area. At least two clamping plates 2k are fixed on one of the two connected ring plates 1k, and a slot 3k is formed between the ring plate 1k; the other ring plate 1k is suitable for being inserted and fixed in the slot 3k.

[0030] In this embodiment, Figure 1 As shown, 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.

[0031] In this embodiment, two ring plates 1k are provided, and both ring plates 1k are semicircular arc-shaped, and the outer wall surface of one ring plate 1k is attached to the inner wall surface of the other ring plate 1k, and holes are punched on the two superimposed bottom plates 11k, and the two ring plates 1k are fixedly connected by bolts. A plurality of assembly holes 5k are also provided on the bottom plate 11k, and the assembly holes 5k match the size of conventional bolts. Bolts passing through the assembly holes 5k are suitable for installing and fixing the anti-entanglement ring on other equipment. Of course, the ring plates 1k can also be three or four, etc., which are connected end to end in sequence to form a circular isolation area. The specific number of ring plates 1k depends on the specific situation.

[0032] 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.

[0033] For example Figure 1 As shown, at least one obstacle clearing opening is provided on the bottom plate 11k for observation or to extend other equipment therefrom. In this embodiment, the obstacle clearing opening is an obstacle clearing groove 4k formed by the inner edge of the arc-shaped bottom plate 11k being recessed toward the outer edge of the arc-shaped bottom plate 11k. The obstacle clearing groove 4k is an isosceles trapezoid as a whole, and the width of the notch is greater than the width of the bottom of the groove. The notch is located on the inner ring of the bottom plate 11k. The hole formed by the bottom plate 11k of the anti-entanglement ring is used to be fixed on the bearing seat. Therefore, the notch is buckled on the surface of the bearing seat. The notch size is large, which is more convenient for observing the internal situation. In this embodiment, two obstacle clearing grooves 4k are provided on the bottom plate 11k of each ring plate 1k, and the four obstacle clearing grooves 4k are evenly spaced on the circumference.

[0034] The annular isolation area is formed by the ring plate 1k, which is suitable for being sleeved and fixed on the driving shaft and blocked in the gap to prevent weeds or straw from being entangled on the driving shaft.
