Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of knotter test benches, and more specifically, to a small square hay bale press knotter test bench. Background Technology
[0002] A square bale pick-up and baler is a forage harvesting machine that compresses hay into rectangular bales for easy transportation and storage. The knotter is the core component of the square bale baler. Within 0.6-0.7 seconds, the knotter can complete actions such as feeding rope, clamping rope, winding rope, cutting rope, returning to its original position, and releasing the knot. These actions are performed by the cams that make up the knotter. In order to study the various motion processes of the knotter, the knotter test bench in the existing technology has emerged. By designing and manufacturing the test bench, the motion process of the knotter can be clearly observed, and newly manufactured knotters can be tested to study their performance.
[0003] Existing knotter test stations inevitably use knotting ropes during operation. There are many types of knotting ropes, and some whole rolls of rope, lacking a hollow core at the center, are typically laid horizontally in the hopper during installation. This causes the rope to jump and deviate during unwinding, making it prone to unraveling and hindering stable material feeding. Furthermore, because the rope is in direct contact with the hopper's inner wall, excessive friction during unwinding can easily lead to breakage. These issues present several drawbacks in its use.
[0004] In view of this, we propose a test bench for a small square bale press knotter. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A test bench for a small square bale press knotter includes a test bench body 1. A base plate 2 is fixedly mounted on the lower side of the test bench body 1. A hopper 3 is fixedly mounted on the upper side of the base plate 2. A fixed box 4 is fixedly mounted on the outer side of the hopper 3. A movable block 8 is movably mounted inside the fixed box 4. Connecting blocks 7 are rotatably mounted on both sides of the movable block 8. A slider 6 is rotatably mounted on the outer side of the connecting block 7. A movable rod 12 is fixedly mounted on the outer side of the slider 6. The movable rod 12 movably passes through the fixed box 4 and extends to the outer side, with the outer end of the movable rod 12 located on the outer side of the fixed box 4. A fixed rod 13 is fixedly installed, with its outer end extending movably into the inner side of the hopper 3. A turntable 14 is rotatably installed on the part of the outer end of the fixed rod 13 located inside the hopper 3. Two sets of springs 11 are installed inside the fixed box 4. One end of each set of springs 11 is connected to both sides of the fixed box 4, and the other end of each spring 11 is connected to the slider 6. After the two sets of turntables 14 limit the knotted rope, the knotted rope can rotate on its own and drive the turntables 14 to rotate during the rope release process, which ensures the stability of rope release and improves the convenience of rope release.
[0029] Specifically, a limiting rod 5 is fixedly installed inside the fixed box 4. The limiting rod 5 moves through the slider 6 and can limit the slider 6, so that the slider 6 moves along the limiting rod 5, thereby improving the movement stability of the slider 6.
[0030] Furthermore, a connecting rod 9 is fixedly installed on the outside of the movable block 8. The connecting rod 9 moves through the fixed box 4 and extends to the outside. A handle 10 is fixedly installed on the outer end of the connecting rod 9 located on the outer part of the fixed box 4. By pressing the handle, the two sets of turntables 14 can be moved simultaneously, improving the convenience of limiting the knotted rope.
[0031] It is worth noting that a fixed frame 15 is fixedly installed on the upper side of the base plate 2, and a support block 16 is movably inserted into the inner side of the fixed frame 15. The support block 16 movably passes through the fixed frame 15 and extends to the outside. A roller 17 is fixedly installed on the outer end of the support block 16 located on the outer part of the fixed frame 15. By setting the roller 17, the knotted rope can be further limited, thereby improving the stability of the knotted rope's feeding.
[0032] It is worth noting that an installation frame 18 is fixedly installed on the bottom side of the hopper 3. Multiple sets of rollers 19 are rotatably installed inside the installation frame 18. When the knotted rope is released, it can drive the rollers 19 to rotate inside the installation frame 18, thereby reducing the friction when releasing the rope and making the release of the rope more convenient.
[0033] In addition, a threaded rod 20 is fixedly installed on the outside of the support block 16. The threaded rod 20 moves through the fixed frame 15 and extends to the outside. A wing nut 21 is threaded on the outer part of the threaded rod 20 located outside the fixed frame 15. A sliding groove 22 is opened through the outside of the fixed frame 15 to engage the threaded rod 20. By loosening or tightening the wing nut 21, the roller 17 can be adjusted and fixed, so as to facilitate supporting the knotted rope in a suitable position and meet different usage needs.
[0034] Working principle: First, pressing the handle 10 moves the connecting rod 9 inward to the fixed box 4. When the connecting rod 9 moves, it moves the movable block 8. When the movable block 8 moves, it moves the connecting blocks 7 on both sides. The connecting blocks 7 move the slider 6 on the limiting rod 5 and squeeze the spring 11. Then, the whole roll of knotted rope is placed on the roller 19 inside the mounting frame 18. Finally, the handle 10 is released. At this time, the rebound force of the spring 11 moves the two sets of turntables 14 and fits against both sides of the knotted rope, which facilitates the limiting of the knotted rope.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
