Description

Technical Field

[0001] This utility model relates to the technical field of tensioning rod devices, and in particular to a tensioning rod device for agricultural machinery belts. Background Technology

[0002] In the field of agricultural machinery technology, belt drive systems are widely used in various agricultural machinery equipment such as tractors, harvesters, and seeders due to their simple structure, smooth transmission, and low cost, to realize power transmission and motion conversion. As a key component of the transmission system, the belt tensioning device maintains the appropriate tension of the belt to prevent slippage, tooth skipping, or excessive wear, thereby ensuring the reliability and efficiency of the transmission.

[0003] Existing belt tensioning devices for agricultural machinery mostly adopt traditional mechanical structures, with common solutions including automatic spring tensioning mechanisms and manually adjustable tensioning rods. Among them, the automatic spring tensioning device uses the preload of the spring to automatically compensate for belt elongation, which has the advantages of compact structure and certain self-adaptive ability. However, during use, the spring is prone to failure due to fatigue or temperature changes, resulting in unstable tension and inability to achieve precise control. Especially in the dynamic operating environment of agricultural machinery, with large load fluctuations and frequent vibrations, belt loosening or over-tensioning can easily occur, which not only reduces transmission accuracy but may also accelerate the wear of parts and shorten the equipment life. Therefore, improvements are needed. Utility Model Content

[0067] During operation, rotating the adjustment disc 12 causes the adjustment shaft 11, which is fixedly connected to the adjustment disc 12, to rotate on the adjustment block 10.

[0069] During operation, the sliding tooth block 14, which is threadedly connected to the adjusting shaft 11, rotates, causing the sliding tooth block 14 to slide in the sliding groove 13, which in turn causes the first sliding gear 16, which meshes with the sliding tooth block 14, to rotate. This causes the sliding shaft 15, which is fixedly connected to the first sliding gear 16, to rotate on the support block 1, which in turn causes the second sliding gear 17, which is fixedly connected to the sliding shaft 15, to rotate.

[0070] Reference Figure 2 and Figure 4 In a preferred embodiment, the transmission component includes: a transmission groove 18, which is formed in the support block 1; a transmission gear plate 19, which is disposed in the transmission groove 18, slidably connected to the transmission groove 18, and meshing with the second sliding gear 17; a transmission plate 20, which is fixedly connected to the transmission gear plate 19, slidably connected to the second support groove 3, and also slidably connected to the transmission groove 18; and an adjusting plate 9 is fixedly connected to the transmission plate 20.

[0071] During operation, the transmission gear plate 19, which meshes with the second sliding gear 17, slides in the transmission groove 18, causing the transmission plate 20, which is fixedly connected to the transmission gear plate 19, to slide in the transmission groove 18. This causes the adjusting plate 9, which is fixedly connected to the transmission plate 20, to slide in the first support groove 2, thereby causing the adjusting plate 9 to drive the support plate 4 to slide in the first support groove 2.

[0072] Reference Figure 5In a preferred embodiment, the clamping mechanism includes: a clamping frame 21, disposed on the support plate 4 and fixedly connected to the support plate 4; a clamping rod 22, disposed inside the clamping frame 21 and fixedly connected to the clamping frame 21; a clamping sleeve 23, slidably connected to the clamping rod 22 and slidably connected to the clamping frame 21; a clamping disc 24, fixedly connected to the clamping sleeve 23; and an elastic component disposed on the clamping sleeve 23.

[0073] During operation, pressing the clamping plate 24 moves the clamping plate 24 closer to the clamping frame 21, causing the clamping sleeve 23, which is fixedly connected to the clamping plate 24, to slide on the clamping rod 22 and the clamping frame 21.

[0074] Reference Figure 5 In a preferred embodiment, the elastic component includes: an elastic block 25, disposed on the clamping sleeve 23 and fixedly connected to the clamping sleeve 23; an elastic spring 26, one end of which is fixedly connected to the elastic block 25 and the other end of which is fixedly connected to the clamping frame 21; two first elastic shafts 27, which are symmetrically disposed on the elastic block 25 and fixedly connected to the elastic block 25; an elastic plate 28, which is rotatably connected to the first elastic shafts 27; a second elastic shaft 29, which is rotatably connected to the elastic plate 28; and a moving component disposed on the clamping frame 21.

[0075] During operation, the elastic block 25, which is fixedly connected to the clamping sleeve 23, slides within the clamping frame 21, causing the elastic spring 26, which is fixedly connected to the elastic block 25, to be compressed, generating elastic potential energy, which drives the elastic plate 28, which is rotatably connected to the first elastic shaft 27, to rotate.

[0076] Reference Figure 5 In a preferred embodiment, the moving component includes: a moving groove 30, which is formed on the clamping frame 21; two moving blocks 31, which are symmetrically arranged in the moving groove 30, slidably connected to the moving groove 30, and fixedly connected to the second elastic shaft 29; a moving plate 32, which is fixedly connected to the moving blocks 31; and a moving column 33, which is fixedly connected to the moving plate 32 and slidably connected to the support hole 8.

[0077] During operation, the movable block 31, which is fixedly connected to the second elastic shaft 29, slides in the movable groove 30, causing the movable plate 32, which is fixedly connected to the movable block 31, to move away from each other, so that the movable column 33 slides outward from the support hole 8.

[0078] Working principle: When the tension wheel 6 needs to be disassembled, press the clamping plate 24 to move the clamping plate 24 closer to the clamping frame 21, so that the clamping sleeve 23 fixedly connected to the clamping plate 24 slides on the clamping rod 22 and the clamping frame 21, causing the elastic block 25 fixedly connected to the clamping sleeve 23 to slide in the clamping frame 21, so that the elastic spring 26 fixedly connected to the elastic block 25 is compressed, generating elastic potential energy, which drives the elastic plate 28 rotatably connected to the first elastic shaft 27 to rotate, so that the moving block 31 fixedly connected to the second elastic shaft 29 slides in the moving groove 30, causing the moving plate 32 fixedly connected to the moving block 31 to move away from each other, so that the moving column 33 slides to the outside of the support hole 8, thereby realizing the disassembly and replacement of the tension wheel 6;

[0079] Then, when it is necessary to adjust the spacing between the support plates 4, rotate the adjusting disc 12, causing the adjusting shaft 11, which is fixedly connected to the adjusting disc 12, to rotate on the adjusting block 10. This causes the sliding tooth block 14, which is threadedly connected to the adjusting shaft 11, to rotate, causing the sliding tooth block 14 to slide in the sliding groove 13. This causes the first sliding gear 16, which meshes with the sliding tooth block 14, to rotate, causing the sliding shaft 15, which is fixedly connected to the first sliding gear 16, to rotate on the support block 1. This causes the second sliding gear 17, which is fixedly connected to the sliding shaft 15, to rotate, causing the transmission tooth plate 19, which meshes with the second sliding gear 17, to slide in the transmission groove 18. This causes the transmission plate 20, which is fixedly connected to the transmission tooth plate 19, to slide in the transmission groove 18, causing the adjusting plate 9, which is fixedly connected to the transmission plate 20, to slide in the first support groove 2. This causes the adjusting plate 9 to drive the support plate 4 to slide in the first support groove 2, thereby adjusting the spacing between the support plates 4 and facilitating the adjustment of the tension of the support spring 5.
