Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a pick-up device for a round baler without a protective ring. Background Technology

[0002] In mechanized agricultural operations, round balers are essential equipment for harvesting and baling crop residues such as hay and straw. Pickups are the main devices used in round balers to collect crop residues. Traditional pickups are usually equipped with protective rings to prevent crop residue from scattering during pickup. However, these protective rings can be worn down by the crop during use, leading to decreased pickup efficiency and increased maintenance costs. Furthermore, the presence of the protective rings limits the adaptability of the pickups, restricting their application to different crops and terrain conditions. Therefore, this invention proposes a protective ring-less pickup for round balers. Utility Model Content

[0003] The purpose of this invention is to provide a ringless pick-up device for round balers, aiming to solve the above-mentioned problems.

[0027] like Figures 1-4 As shown, this utility model provides a ringless pick-up device for round balers, comprising:

[0028] The frame 1 includes two parallel side plates 11.

[0029] Picking mechanism 2 is rotatably mounted between side plates 11. Picking mechanism 2 includes a central shaft 21, a fixing plate 22, a picking roller 23, and a spring scale 24. The central shaft 21 is rotatably mounted between side plates 11. The fixing plate 22 is fixedly mounted at both ends of the central shaft 21. The picking roller 23 is sleeved on the central shaft 21. The fixing plate 22 is set on both sides of the picking roller 23. The spring scale 24 is mounted on the picking roller 23.

[0030] The unloading mechanism 3 is located between the side plates 11 and above the picking mechanism 2. The unloading mechanism 3 is used to transport the grass picked up by the picking mechanism 2. The unloading mechanism 3 includes an unloading panel 31 with an arc-shaped end. The unloading panel 31 is located above the spring ruler 24.

[0031] In some embodiments of this application, the picking mechanism 2 further includes a spring scale mounting base 25, which is arranged in a ring along the axis of the picking roller 23, and the spring scale 24 is mounted on the spring scale mounting base 25.

[0032] The picking mechanism 2 also includes a spring scale mounting base 25, which is arranged in a ring along the axis of the picking roller 23, ensuring that the spring scale 24 can evenly cover the entire working surface of the picking roller 23. The spring scale 24 is mounted on the spring scale mounting base 25, allowing it to extend and retract flexibly to accommodate materials of different thicknesses and sizes. This design not only improves the adaptability and efficiency of the picking mechanism 2, but also ensures stability and reliability during the picking process through the even distribution of the spring scale 24.

[0033] In some embodiments of this application, the pickup roller 23 is provided with a plurality of mounting ports 231, the number of mounting ports 231 matching the number of spring scale mounting seats 25, and the side wall of the spring scale mounting seat 25 is provided with mounting holes, and the spring scale mounting seat 25 is connected to the pickup roller 23 through the mounting holes.

[0034] In this design, the surface of the pickup roller 23 has multiple mounting holes 231 evenly distributed. The number of these mounting holes 231 is exactly the same as the number of the spring scale mounting bases 25, ensuring that each spring scale mounting base 25 has a corresponding installation position. Mounting holes are designed on the side wall of the spring scale mounting base 25. Through these mounting holes, the spring scale mounting base 25 can be precisely positioned and fixed to the pickup roller 23. To ensure a stable connection, the spring scale mounting base 25 is connected to the mounting holes 231 on the pickup roller 23 by bolts. The entire installation process requires using a bolting tool to pass the bolts through the mounting holes of the spring scale mounting base 25 and screw them into the mounting holes 231 of the pickup roller 23, thereby achieving a secure connection between the spring scale mounting base 25 and the pickup roller 23. This design not only ensures the stability and reliability of the spring scale mounting base 25 but also facilitates subsequent maintenance and replacement.

[0035] In some embodiments of this application, the bottom wall of the spring ruler mounting base 25 is provided with a spring ruler mounting hole, and the spring ruler 24 is connected to the spring ruler mounting base 25 through the spring ruler mounting hole.

[0036] The bottom wall of the spring ruler mounting base 25 is machined with one or more spring ruler mounting holes, the size and position of which match the dimensions of the spring ruler 24. To ensure the stability of the spring ruler 24 and facilitate replacement, the spring ruler 24 is bolted to the spring ruler mounting base 25. This means that one or both ends of the spring ruler 24 have threaded holes, and the spring ruler mounting base 25 has corresponding threaded holes or threaded grooves. By passing the bolt through the threaded hole of the spring ruler 24 and screwing it into the threaded hole or threaded groove of the spring ruler mounting base 25, the spring ruler 24 is firmly fixed to the spring ruler mounting base 25. This connection method not only ensures the stability and accuracy of the spring ruler 24 during use, but also allows for easy replacement or maintenance of the spring ruler 24 by loosening the bolts.

[0037] In some embodiments of this application, the spring ruler 24 includes a fixed section 241, a spiral section 242, a first elongated section 243, and a second elongated section 244. Two spiral sections 242, two first elongated sections 243, and two elongated sections 244 are provided. The spiral section 242 is disposed at both ends of the fixed section 241. The first elongated section 243 is connected to the spiral section 242, and the second elongated section 244 is smoothly connected to the first elongated section 243.

[0038] In some embodiments of this application, the length of the first long strip 243 is greater than the length of the second long strip 244, and the first long strip 243 and the second long strip 244 form an angle, which is an obtuse angle.

[0039] In some embodiments of this application, the unloading mechanism 3 further includes a connecting plate 32, a slider 33, an adjusting rod 34, and a positioning bolt 35. The unloading panel 31 is fixedly connected to the connecting plate 32, the adjusting rod 34 is fixedly installed on the side plate 11, and sliders 33 are provided on both sides of the connecting plate 32. The connecting plate 32 is slidably connected to the adjusting rod 34 through the sliders 33, and the sliders 33 and the adjusting rod 34 are positioned by the positioning bolt 35.

[0040] In the unloading mechanism 3, the unloading panel 31 is responsible for collecting and unloading hay. To ensure the flexible and stable operation of the unloading panel 31, it is fixedly connected to the connecting plate 32. The connecting plate 32, acting as a bridge between the unloading panel 31 and the adjusting rod 34, is of crucial design. The adjusting rod 34 is fixedly mounted on the side plate 11. The setting of the adjusting rod 34 allows the user to adjust the position of the unloading panel 31 as needed to adapt to different unloading requirements. Sliding blocks 33 are provided on both sides of the connecting plate 32, allowing the connecting plate 32 to slide on the adjusting rod 34. The sliding connection between the sliding blocks 33 and the adjusting rod 34 ensures the flexibility and stability of the unloading panel 31 during operation.

[0041] To ensure a secure connection between the slider 33 and the adjusting rod 34, a positioning bolt 35 is used. The positioning bolt 35 secures the slider 33 to a specific position on the adjusting rod 34, preventing unnecessary movement during operation. By adjusting the positioning bolt 35, the user can precisely position the unloading panel 31, ensuring the accuracy and efficiency of the unloading operation.

[0042] In some embodiments of this application, a plurality of unloading panels 31 are provided, and the number of unloading panels 31 matches the number of spring scales 24 distributed along the axial direction of the pickup roller 23.

[0043] In some embodiments of this application, the picking roller 23 is provided with several sets of baffles 232, the baffles 232 are positioned corresponding to the two sides of each spring ruler 24, and the unloading panel 31 is disposed between each set of baffles 232.

[0044] In this embodiment, since the unloading panel 31 is installed above the spring scale 24, the number of unloading panels 31 is the same as the number of spring scales 24 distributed along the axial direction of the pickup roller 23, that is, the number of spring scales 24 in each row. The end point of the unloading panel 31 is directly above the spring scale 24.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
