Description

Technical Field

[0001] This utility model relates to the field of shredder rollers for harvesting both stems and ears of grain, and particularly to a cutter roller and a cutter roller device. Background Technology

[0002] This technology development is based on the high precision and cost considerations of manufacturing shredder rollers for combined stalk and ear harvesters. As a core component of combined stalk and ear harvesters, the shredder roller's function is to chop the straw and then throw it to the blower, possessing both chopping and some throwing capabilities. High precision in the shape and dimensions of the shredder roller is essential to ensure good chopping performance and a certain level of throwing capability.

[0003] Currently, its structure consists of a machined shell of a large-diameter steel pipe cutter roller, a support plate, and a moving cutter holder. The manufacturing process involves welding and machining. After welding the roller body, support plate, and cutter holder, the mounting surface and threaded holes for the cutter holder are machined. This process is quite complex. The welding process has low precision, making it impossible to achieve high-precision cutter roller welding. Post-weld machining is then used to maintain the consistency of the cutter roller. Utility Model Content

The left casting cutter roller 1 and the right casting cutter roller 2 are coaxially connected to form a shredding roller 11.

[0038] The beneficial effects of adopting this utility model's technical solution are as follows: Combining the casting process with an analysis of casting feasibility, and from a casting process perspective, it departs from the inability to cast integrated casting solutions and instead adopts a split-type cutter roll casting method. This involves casting left and right cutter rolls, with the cutter holder and roll body cast as a single piece. This solves the problem of insufficient precision in welded moving cutter holders and addresses the issue of high manufacturing costs for cutter rolls. It reduces manufacturing costs, ensures machining and assembly accuracy, and improves upon defects caused by manufacturing processes.

[0039] like Figures 1 to 3 As shown, furthermore, the roller body 14 on the left casting cutter roller 1 and the right casting cutter roller 2, the moving cutter holder 3, and the transition area 4 of the roller body itself are all fully curved surfaces.

[0040] The beneficial effects of adopting the above-mentioned further technical solution are: the full-curved surface design between the cutter roller body and the moving cutter holder, as well as between the transition area of ​​the roller body itself, avoids the welding stress concentration effect and the cutting stress concentration phenomenon during the cutting operation of the cutter roller. It solves the problem of welding stress concentration caused by the welding process of the moving cutter holder, the problem of welding stress concentration caused by the uneven transition connection at the welded joint, and the problem of uneven curved surface of the transition weld between the moving cutter holder and the roller body in welded cutter rollers.

A movable cutter and a pressure plate 25 are mounted on the movable cutter mounting surface 8, and the movable cutter is located between the movable cutter mounting surface 8 and the pressure plate 25.

[0044] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the moving blade mounting surfaces of the multiple moving blade holders are used to mount the moving blades. The moving blade mounting surfaces of the moving blade holders are provided with moving blade mounting threaded holes, facilitating the detachable mounting of the moving blades on the moving blade mounting surfaces of the moving blade holders via bolts, thus simplifying the installation and maintenance of the moving blades. The pressure plate facilitates the clamping and installation of the moving blades, preventing them from shaking and improving their stability and reliability.

[0046] The beneficial effects of adopting the above-mentioned further technical solution are: the shredding roller is equipped with a balance block mounting hole for dynamic balancing after the blades are installed. Since it is cast and shaped using a casting mold, the dimensional accuracy of the cast blade roller is easily guaranteed. By selecting the appropriate manufacturing process, manufacturing costs are reduced, assembly accuracy is ensured, defects caused by the manufacturing process are mitigated, and the advantages of the cast blade roller manufacturing process are clearly demonstrated.

[0047] This utility model is an integrated cast cutter roller (cutter roller) designed to address the high manufacturing costs and inability to guarantee processing accuracy of shredder rollers. In existing technologies, the manufacturing process of shredder rollers suffers from poor consistency in processing accuracy and high processing costs.

The number of cutter holders is not limited to 24. The casting material can be QT450 (casting material is not limited to QT450), with a tensile strength ≥450MPa. They are formed by casting molds, ensuring the dimensional accuracy of the cast cutter rollers. The area between the cutter roller body 14 and the moving cutter holder 3, and the transition area 4 within the roller body itself, is a fully curved surface. The maximum thickness is 18mm (not limited to wall thickness) and the minimum is 12mm (not limited to wall thickness), avoiding welding stress concentration effects and cutting stress concentration during the cutter roller cutting operation. The split-type cutter roller has a fine threaded hole 5 in the middle mounting plane. The fine M12 threaded hole 6 needs to be machined by a drilling machine. The left and right integrated cast cutter rollers (left cast cutter roller 1 and right cast cutter roller 2) are connected by M12 bolts 7. The moving cutter mounting surface 8 of the cutter roller moving cutter seat has a moving cutter mounting threaded hole. The fine M16 threaded hole 9 needs to be machined by a drilling machine.

The pressure plate 25 is installed on the upper part of the moving cutter to complete the assembly of the shredding roller 11. The shredding roller 11 has a balance block mounting hole 24 for dynamic balancing after the cutter is installed.

[0050] By selecting appropriate manufacturing processes, processing costs were reduced, processing and assembly accuracy was ensured, defects caused by manufacturing processes were mitigated, and the benefits of the casting cutter roll processing technology were clarified.

[0051] The shredder roller (shredder roller 11) is a circular roller. As an alternative to the above solution, one option is a disc-type shredder roller, which can be formed by welding three discs to the moving cutter holder to create a circular roller.

Axial positioning is achieved through a retaining ring (shaft end retaining ring) and connected to the cutter roller to transmit power.

[0065] like Figure 8 and Figure 9 As shown, its three half-shafts are made of 42CrMo. Power is transmitted to the cutter roller through bolted connection between the left half-shaft 22 and the right half-shaft 23. The half-shaft bolt connection is used to self-position the cutter roller. The left and right sides are connected to the side walls of the shredding housing 26 through bearing seats 15 to fix the cutter roller. Power is transmitted through pulley connection. The right pulley 16 is circumferentially positioned by a flat key. The first clamp 17 is axially positioned and connected to the right half-shaft (right half-shaft 23) of the cutter roller to transmit power. The left pulley 18 is circumferentially positioned and connected to the left half-shaft (left half-shaft 22) through spline hub 19. Axial positioning is achieved by retaining ring (shaft end retaining ring 20) and connected to the cutter roller to transmit power.
