Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a shredding device and operating machinery. Background Technology

[0002] During the harvesting process, the moving blades of a silage harvester repeatedly cut the material, causing wear on the blades. After a long period of operation, the blades become dull and need to be sharpened, which also leads to wear. The wear of the blades causes the outer diameter of the blades to gradually decrease, which in turn increases the gap between the moving blades and the stationary blades, as well as the gap between the moving blades and the base plate. This affects the consistency of material cutting and the efficiency of material throwing.

[0003] Currently, the gap between the moving blade and the base plate is adjusted by stopping the silage harvester and then adjusting the shims on the base plate to reduce the gap. This operation is complicated, the gap size is difficult to control, and stopping the machine affects harvesting efficiency. In addition, the gap is usually adjusted only after multiple sharpenings of the moving blade, during which the gap between the moving blade and the base plate increases continuously. The gap adjustment between the moving blade and the base plate is inconvenient, the material cutting size is inconsistent, and the quality of material harvesting is affected. Utility Model Content

[0050] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0051] The shredding device of this utility model is described below with reference to the accompanying drawings.

[0052] like Figures 1 to 6 As shown, this utility model provides a chopping device, which includes a housing 10, a fixed blade adjustment mechanism, and a gap adjustment mechanism. The housing 10 is provided with a moving blade assembly 11. The fixed blade adjustment mechanism includes a swing drive module 20 and a fixed blade mounting beam 40 for mounting the fixed blade 30. The fixed blade mounting beam 40 is rotatably mounted on the housing 10 and spaced apart on the front side of the moving blade assembly 11. The swing drive module 20 is mounted on the housing 10 and drivenly connected to the fixed blade mounting beam 40. The gap adjustment mechanism includes a rocker arm 50 and an adjustable base plate 60. The rocker arm 50 is hinged to the housing 10. The adjustable base plate 60 is spaced apart below the moving blade assembly 11, and one end of the adjustable base plate 60 is rotatably connected to the fixed blade mounting beam 40, and the other end is hinged to the rocker arm 50.

[0053] It should be noted that the shredding device of this utility model can be used in machinery for cutting agricultural materials. The machinery can be a silage harvester, a forage harvester, or other agricultural harvesters, and the materials can be silage crops, yellow silage crops, or crop straw, etc.

[0054] Specifically, the housing 10 is used for installation on the operating machinery. A moving blade assembly 11 is installed inside the housing 10. A fixed blade mounting beam 40 is provided on the front side of the housing 10. A fixed blade 30 is provided on the fixed blade mounting beam 40. The moving blade assembly 11 can rotate relative to the housing 10 and cooperate with the fixed blade 30 to cut materials. The swing drive module 20 is connected to the fixed blade mounting beam 40 and can drive the fixed blade mounting beam 40 to swing, so that the fixed blade mounting beam 40 drives the fixed blade 30 to swing toward the moving blade assembly 11 to adjust the gap between the fixed blade 30 and the moving blade assembly 11. The fixed blade mounting beam 40 drives the adjustable base plate 60 and the end of the fixed blade mounting beam 40 to rotate toward the moving blade assembly 11, so that the adjustable base plate 60 drives the rocker arm 50 to swing relative to the housing 10, so that the end of the adjustable base plate 60 and the rocker arm 50 hinged together moves toward the moving blade assembly 11 synchronously. In this way, the shredding device drives the fixed blade mounting beam 40 to swing through the swing drive module 20, so as to synchronously adjust the gap between the fixed blade 30 and the moving blade assembly 11 and the gap between the adjustable base plate 60 and the moving blade assembly 11. The adjustment is convenient and quick, without the need to stop the machine, which improves the harvesting efficiency. Moreover, it can be adjusted during operation, so that the gap between the adjustable base plate 60 and the moving blade assembly 11 is always kept within a suitable size range, which improves the consistency of material cutting size and improves the quality of material harvesting.

[0055] In this embodiment of the utility model, the adjustable base plate 60 includes an adjustable part 61 and a connecting part 62. The adjustable part 61 is arc-shaped and spaced below the moving blade assembly 11. The adjustable part 61 is hinged to the fixed blade mounting beam 40. The connecting part 62 is located on one side of the adjustable part 61 and forms a hinge ear 621. The hinge ear 621 is located at the end of the connecting part 62 away from the fixed blade mounting beam 40, and the hinge ear 621 is hinged to the end of the rocker arm 50 away from the housing 10.

[0056] like Figures 3 to 6As shown, the adjustable part 61 is arc-shaped and surrounds the outer periphery of the moving blade assembly 11. The adjustable part 61 and the moving blade assembly 11 are spaced apart to form a gap for material to pass through. The front end of the adjustable part 61 is hinged to the fixed blade mounting beam 40. The connecting part 62 is connected to the adjustable part 61 and forms a hinge ear 621 located at the rear end of the adjustable part 61. One end of the rocker arm 50 is rotatably connected to the housing 10, and the other end of the rocker arm 50 is hinged to the hinge ear 621. The swing drive module 20 drives the fixed blade mounting beam 40 to swing toward the moving blade assembly 11, so that the fixed blade mounting beam 40 drives the adjustable part 61 to swing. The fixed blade mounting beam 40 moves toward the moving blade assembly 11, and during the swinging process, the adjustable part 61 and the connecting part 62 drive the rocker arm 50 to swing relative to the housing 10, so that the end of the rocker arm 50 away from the housing 10 and the hinge ear 621 move toward the moving blade assembly 11, thereby enabling the front and rear ends of the adjustable part 61 to move toward the moving blade assembly 11 synchronously, realizing the adjustment of the gap between the adjustable part 61 and the moving blade assembly 11, and the gap size is uniform before and after, improving the consistency of material cutting size, and the operation machinery does not need to be stopped during the adjustment process, thus improving the harvesting efficiency.

[0057] In this embodiment of the utility model, the fixed blade mounting beam 40 includes a beam body 41 and a rotating column 42. The upper side of the beam body 41 is used for mounting the fixed blade 30, and the rotating column 42 is located on the lower side of the beam body 41. The adjustable part 61 is hinged to the beam body 41. The housing 10 is provided with a mounting seat 12, and a mounting groove 121 is formed on the mounting seat 12. The rotating column 42 is rotatably disposed in the mounting groove 121. The swing drive module 20 is drivenly connected to the beam body 41 and is used to drive the beam body 41 to swing around the rotating column 42 as the swing center.

[0058] like Figures 2 to 6 As shown, the swing drive module 20 drives the beam body 41 to swing, causing the beam body 41 to swing around the rotating column 42 as the swing center. The beam body 41 drives the fixed blade 30 to swing towards the moving blade assembly 11 to adjust the gap between the fixed blade 30 and the moving blade assembly 11. In addition, the beam body 41 drives the front end of the adjustable part 61 to move towards the moving blade assembly 11 to adjust the gap between the front end of the adjustable part 61 and the moving blade assembly 11. During the swing, the beam body 41 drives the adjustable part 61 and the connecting part 62. Since one end of the rocker arm 50 is connected to the housing 10, the other end of the rocker arm 50 is connected to the housing 10. The hinge ear 621 drives the rear end of the adjustable part 61 to move toward the moving blade assembly 11 through the connecting part 62, so as to adjust the gap between the rear end of the adjustable part 61 and the moving blade assembly 11. This realizes the synchronous adjustment of the gap between the fixed blade 30, the front end of the adjustable part 61 and the rear end of the adjustable part 61 and the moving blade assembly 11, which is efficient and convenient. In addition, the mounting base 12 has a mounting groove 121 with an upper opening. The rotating column 42 is installed in the mounting groove 121 and can rotate in the mounting groove 121 to drive the beam body 41 to swing, which facilitates assembly and improves the smoothness of the swing of the beam body 41.

[0059] In this embodiment of the utility model, the fixed blade adjustment mechanism further includes a hinge block 43. A hinge groove 411 is provided on the beam body 41. One end of the hinge block 43 is hinged in the hinge groove 411, and the other end of the hinge block 43 is connected to the adjustable part 61. Figures 4 to 6 As shown, a hinge groove 411 is provided on the side of the beam body 41 facing the moving knife assembly 11. A hinge block 43 is provided in the hinge groove 411. The hinge block 43 can rotate in the hinge groove 411 and can be connected to the adjustable part 61 through fasteners. The beam body 41 can swing around the rotating column 42 as the swing center to drive the hinge block 43 and the adjustable part 61 to move. The installation is convenient and quick and the connection is stable and reliable.

[0060] Furthermore, such as Figures 1 to 3 As shown, the moving blade assembly 11 includes a moving blade roller 111 and a moving blade 112. The moving blade roller 111 is rotatably mounted on the housing 10, and the moving blade 112 is mounted on the moving blade roller 111 and located inside the housing 10. The moving blade 112 will wear after prolonged use or after sharpening, and the gap between the worn moving blade 112 and the fixed blade 30 and the adjustable part 61 will increase. Figure 6 As shown, the swing drive module 20 drives the beam body 41 to swing around the rotating column 42 as the swing center. That is, the swing drive module 20 drives the beam body 41 to swing around point A. The beam body 41 drives the fixed blade 30 to swing backward, so that the gap between the fixed blade 30 and the moving blade 112 is reduced. The beam body 41 pushes the hinge block 43 backward, so that the hinge block 43 drives the front end of the adjustable part 61 to move towards the moving blade 112. The beam body 41 pushes the adjustable part 61 backward through the hinge block 43. The adjustable part 61 is hinged to the rocker arm 50 through the hinge ear 621 on the connecting part 62. The rocker arm 50 swings around point D, so that the rear end of the adjustable part 61 moves towards the moving blade 112 synchronously. Since the dimensions of the beam body 41, the adjustable base plate 60 and the rocker arm 50 are fixed, the distance between point A and point B, the distance between point B and point C, and the distance between point C and point D are fixed. With points A and D located on the shell, the beam body 41, adjustable base plate 60, and rocker arm 50 form a hinged four-bar linkage. The shredding device can synchronously adjust the gap between the fixed blade 30 and the moving blade 112, as well as the gap between the adjustable base plate 60 and the moving blade 112, by driving the beam body 41 to swing through the swing drive module 20. The adjustment is flexible and convenient, and there is no need to stop the operating machinery. The shredding device can adjust the gap at any time during operation, ensuring the consistency of the gap size and improving the quality and efficiency of material harvesting. In addition, those skilled in the art will understand that by reasonably designing the dimensions of the beam body 41, adjustable base plate 60, and rocker arm 50, the moving distance of the fixed blade 30 can be made consistent with the moving distance of the adjustable base plate 60, that is, the gap adjustment amount of the fixed blade 30 is equal to the gap adjustment amount of the adjustable base plate 60, which further improves the synchronization of adjustment.

[0061] In this embodiment of the utility model, the swing drive module 20 includes a swing drive assembly 21 and a swing push rod 22. The swing drive assembly 21 is disposed on the housing 10. One end of the swing push rod 22 is connected to the beam body 41. The other end of the swing drive assembly 21 and the swing push rod 22 are driven to drive the swing push rod 22 to drive the beam body 41 to swing around the rotating column 42 as the swing center.

[0062] like Figures 2 to 5 As shown, the upper end of the swing push rod 22 is driven to be connected to the swing drive assembly 21, and the lower end of the swing push rod 22 can be connected to the beam body 41 through fasteners. The swing drive assembly 21 drives the swing push rod 22 to swing, so that the swing push rod 22 drives the beam body 41 to swing, thereby causing the beam body 41 to synchronously drive the fixed blade 30, the front end of the adjustable part 61 and the rear end of the adjustable part 61 to move towards the moving blade assembly 11. The gap adjustment is convenient and quick, without the need for manual adjustment, which improves the adjustment efficiency.

[0063] Furthermore, the swing drive assembly 21 includes a swing drive component, a guide rod 211, and a moving block 212. The swing drive component is disposed on the housing 10. The guide rod 211 extends in the front-rear direction. The swing drive component is driven to connect with the guide rod 211 and is used to drive the guide rod 211 to rotate. The moving block 212 is movably sleeved on the guide rod 211 and connected to the end of the swing push rod 22 away from the beam body 41.

[0064] like Figure 7 As shown, one end of the guide rod 211 is driven to the swing drive component, which drives the guide rod 211 to rotate. A moving block 212 is sleeved on the guide rod 211. The moving block 212 is threadedly connected to the guide rod 211 and can move along the extension direction of the guide rod 211. The moving block 212 is rotatably connected to the upper end of the swing push rod 22. The swing drive component drives the guide rod 211 to rotate, which causes the guide rod 211 to drive the moving block 212 to move towards the rear along the guide rod 211. The moving block 212 drives the swing push rod 22 to swing towards the rear, which in turn causes the swing push rod 22 to drive the beam body 41 to swing. The movement is smooth and stable. Furthermore, the movement distance of the fixed blade 30 and the adjustable base plate 60 can be controlled by adjusting the pitch of the external thread on the guide rod 211 and the number of rotations of the guide rod 211, which improves the accuracy of the gap size adjustment and further improves the consistency of the material cutting size.

[0065] In a preferred embodiment of this utility model, a distance sensor is provided on the housing 10. The distance sensor is used to detect the distance between the fixed blade 30 and the moving blade 112. The distance sensor and the swing drive are respectively connected to the controller of the working machine. The distance sensor sends the distance measurement result to the controller. The controller can control the swing drive to start and drive the guide rod 211 to rotate according to the distance measurement result, thereby realizing the automatic adjustment of the gap size. It can also accurately control the gap size according to the distance measurement result, further improving the consistency of the material cutting size.

[0066] In this embodiment of the utility model, the gap adjustment mechanism further includes an eccentric adjustment component, which includes an adjustment plate 70 and an eccentric pin 80. The adjustment plate 70 is connected to the end of the rocker arm 50 away from the housing 10. A through hole 51 is provided on the rocker arm 50 at the position corresponding to the adjustment plate 70. The eccentric pin 80 is provided on the adjustment plate 70. The eccentric pin 80 passes through the through hole 51 and is eccentrically set relative to the through hole 51. The end of the adjustable base plate 60 away from the fixed blade mounting beam 40 is hinged to the eccentric pin 80.

[0067] like Figure 3 , Figure 8 and Figure 9 As shown, an eccentric pin 80 is provided on the adjusting plate 70. The eccentric pin 80 passes through the through hole 51 and is hinged to the hinge ear 621, so that the rocker arm 50 can move the hinge ear 621 and the adjustable part 61 through the eccentric pin 80. Furthermore, the eccentric pin 80 is eccentrically positioned relative to the center of the through hole 51. By adjusting the position of the adjusting plate 70 connected to the rocker arm 50, the eccentric position of the eccentric pin 80 in the through hole 51 can be adjusted. Since the hinge ear 621 is hinged to the eccentric pin 80, the hinge ear 621 can be adjusted to different positions by the eccentric pin 80. When in an eccentric position, it can move to different positions with the eccentric pin 80, thereby adjusting the gap between the hinge ear 621 and the moving blade assembly 11. The hinge ear 621 is provided on the connecting part 62, and the connecting part 62 is provided on the adjustable part 61. The gap between the adjustable part 61 and the moving blade assembly 11 can be adjusted by adjusting the connection position of the adjusting plate 70 on the rocker arm 50. This makes it easy to adjust the initial gap size between the adjustable part 61 and the moving blade assembly 11 according to the type and size of the material to be harvested, thereby improving the quality of material harvesting.

[0068] Furthermore, a mounting boss 71 is formed on the adjusting plate 70. The mounting boss 71 is rotatably mounted in the through hole 51, and the eccentric pin 80 is connected to the mounting boss 71 and is eccentrically positioned relative to the mounting boss 71. Figures 8 to 11As shown, the rocker arm 50 is sleeved on the mounting boss 71. The mounting boss 71 is cylindrical and can rotate within the through hole 51. The eccentric pin 80 is connected to the mounting boss 71 and is eccentrically positioned relative to the axis of the mounting boss 71, so that the eccentric pin 80 is eccentrically positioned relative to the center of the through hole 51. By rotating the adjusting plate 70, the adjusting plate 70 drives the mounting boss 71 to rotate within the through hole 51, thereby causing the mounting boss 71 to drive the eccentric pin 80 to rotate, thus adjusting the eccentric position of the eccentric pin 80. The eccentric pin 80 is set through the hinge ear 621 and hinged to the hinge ear 621. By adjusting the eccentric position of the eccentric pin 80, the distance between the hinge ear 621 and the moving blade assembly 11 can be adjusted, thereby adjusting the initial gap size between the adjustable part 61 and the moving blade assembly 11. This allows the initial gap size between the adjustable part 61 and the moving blade assembly 11 to be adaptively adjusted according to the type and size of the material to be harvested, further improving the quality of material harvesting.

[0069] In this embodiment of the utility model, the adjusting plate 70 includes a mounting part 72 and an adjusting part 73. The mounting boss 71 is provided on the mounting part 72, the adjusting part 73 is connected to the mounting part 72, and the adjusting part 73 is provided with a connecting hole 731. The rocker arm 50 is provided with a plurality of adjusting holes 52. The plurality of adjusting holes 52 are spaced apart from the through hole 51 and arranged sequentially along the outer edge of the through hole 51. The eccentric adjustment assembly also includes an adjusting rod 732, which passes through the connecting hole 731 and is used to pass through any one of the adjusting holes 52.

[0070] like Figures 8 to 11 As shown, the rocker arm 50 has multiple adjustment holes 52 at the end away from the housing 10. The multiple adjustment holes 52 are arranged in an arc shape. The adjustment part 73 has a connecting hole 731. The adjustment rod 732 is used to pass through the connecting hole 731 and any one of the adjustment holes 52 to connect the adjustment part 73 to the rocker arm 50. The mounting part 72 is connected to the adjustment part 73 to form a mounting boss 71. By rotating the adjustment part 73, the adjustment part 73 drives the mounting boss 71 to rotate in the through hole 51.
