Description

Technical Field

[0001] This utility model belongs to the technical field of cotton harvesters, and specifically relates to an outer protective plate for cotton harvesters. Background Technology

[0002] Cotton is widely cultivated in my country. In the past, cotton harvesting mainly relied on manual labor, which was labor-intensive and inefficient. With the continuous improvement of agricultural mechanization in my country, the development of large-scale mechanized cotton harvesting has become an inevitable trend in my country's cotton industry, and thus cotton harvesters have appeared on the market.

[0003] The existing outer protective plate for cotton harvesters requires the use of screws and nuts, which is time-consuming and laborious to disassemble and assemble. In addition, the outer protective plate is equipped with corresponding heat dissipation holes. When the outer protective plate is impacted by external forces, it lacks support and vibration damping. Furthermore, impurities can easily enter the interior of the outer protective plate through the heat dissipation holes during impact. Therefore, a new outer protective plate for cotton harvesters is proposed. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an outer protective plate for a cotton harvester. The outer protective plate for the cotton harvester adopts a sliding arrangement of inner and outer plates, so that the outer plate is buffered when it is impacted, and the adjusting plate is rotated during the impact process to achieve the effect of closing the ventilation holes on the outer plate.

[0005] An outer protective plate for a cotton harvester includes an inner plate, an outer plate slidably disposed on the upper surface of the inner plate, a mounting base disposed on one side of the inner plate, and a fixing mechanism disposed on one side of the inner plate. The fixing mechanism includes a fixing block, an insertion block, and a rotating strip. The fixing block is slidably disposed on one side of the inner plate, the insertion block is slidably disposed on the edge of the inner plate, and a rotating strip is rotatably disposed on one side of the inner plate. The top of the rotating strip overlaps with the fixing block, the bottom of the rotating strip overlaps with the insertion block, a return spring is disposed on one side of the rotating strip, and an extension strip is integrally disposed on the lower surface of the outer plate.

[0006] The beneficial effects of the above technical solution are as follows:

[0007] This design employs a sliding inner and outer panel configuration, which cushions the outer panel upon impact and causes the adjusting plate to rotate during impact, effectively closing the ventilation holes on the outer panel. During installation, pressing the inner panel allows it to automatically insert into the slot via a locking block, achieving a one-way locking effect. During disassembly, pressing the outer panel moves the locking block away from the slot, disengaging it, while simultaneously allowing the horizontal block to enter the insertion port for secondary fixation. To prevent accidental removal of the inner panel, a certain amount of force is required to remove it. Attached Figure Description

[0014] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The embodiments are described in detail below.

[0015] This embodiment provides an outer protective plate for a cotton harvester, as shown in the attached image. Figure 1-5 As shown, the instruction manual is attached. Figure 1 This is a three-dimensional structural diagram of inner panel 1, attached to the instruction manual. Figure 2 Cut the middle section of inner panel 1. (See instruction manual attached.) Figure 3 From the instruction manual appendix Figure 2 Partial details are provided in the instruction manual. Figure 2 It features a wavy line that divides the edge; see instruction manual attached. Figure 4 Cut one side of horizontal block 12. (See instruction manual attached.) Figure 5The outer plate 2 is concealed, and it is slidably mounted on the upper surface of the inner plate 1. A first strip 23 and a second strip 24 are positioned between the inner plate 1 and the outer plate 2. A support spring, a torsion spring, is located at the rotation center of the second strip 24. When the second strip 24 rotates, it torsional the support spring, providing elasticity. This allows the inner plate 1 and outer plate 2 to slide and reset when the outer plate 2 is impacted by an external force. Therefore, the outer plate 2 is reset upon impact, thus mitigating the impact. The inner plate 1 has a sliding mounting block 4 and an insertion block 5 on one side. Both the mounting block 4 and the insertion block 5 are slidably mounted on the inner plate 1, but their edges are square, allowing them to slide smoothly on the inner plate 1. Corresponding slide tracks are provided on the edges of the inner plate 1. A rotating bar 6 is rotatably mounted on the inner plate 1, with its upper end resting on the mounting block 4 and its lower end resting on the insertion block 5. A return spring 7, which is also a torsion spring, is located at the center of rotation of the rotating bar 6, allowing it to move smoothly along the inner plate 1. (See instruction manual for details.) Figure 4 As shown, it remains in its original position. Due to the impact, an extension strip 8 is integrally formed below the outer panel 2. The bottom of the extension strip 8 presses against the rotating strip 6, allowing the rotating strip 6 to rotate clockwise (as shown in the instruction manual). Figure 4Since the rotating bar 6 has slots on both the top and bottom sides, and the middle of the fixing block 4 and the insertion block 5 are circular, they just overlap the rotating bar 6. As the rotating bar 6 rotates clockwise, the fixing block 4 moves away from the slot 11 and the insertion block 5 moves closer to the insertion port 14. A locking block 9 is slidably set on one side of the fixing block 4. There is a buffer spring 10 between the locking block 9 and the fixing block 4. A slot 11 is set on the mounting base 3. The locking block 9 is inserted into the slot 11, making it difficult for the locking block 9 to detach from the slot 11. In this way, the inner plate 1 is difficult to detach from the mounting base 3 without external force. When the outer plate 2 is hit, the locking block 9 moves away from the slot 11, thus contacting the fixing of the locking block 9. However, the insertion block 5 moves closer to the insertion port 14, so that the horizontal block 12 on one side is inserted into the insertion port 14. A horizontal block 12 is rotatably set on one side of the horizontal block 12. A retaining spring 13, which is also a torsion spring, is provided to keep the horizontal block 12 horizontal. The horizontal block 12 is inserted into the insertion port 14. Even if the locking block 9 is away from the locking slot 11, the horizontal block 12 is still inserted into the insertion port 14. At this time, to disassemble, the outer plate 2 needs to be pressed, and the inner plate 1 and outer plate 2 are pulled out together. This forces the retaining spring 13 to rotate in order to remove the inner plate 1 and outer plate 2 (the inner plate 1 has space to facilitate the rotation of the rotating bar 6 and the downward movement of the extension bar 8). This makes the installation and disassembly of the inner plate 1 and outer plate 2 simple. The mounting base 3 is part of the cotton harvester and is a structure that facilitates the installation of the inner plate 1. In order to ensure the heat dissipation of the outer plate 2 and the inner plate 1, this design has an adjusting plate 15 rotatably provided on one side of the outer plate 2. The upper surface of the adjusting plate 15 has ventilation holes, and the surface of the outer plate 2 has corresponding ventilation holes, as shown in the instruction manual. Figure 2 As shown, the two sets of ventilation holes are aligned, allowing the outer plate 2 to dissipate heat. As the outer plate 2 is compressed, to prevent impurities from entering the ventilation holes, the adjusting plate 15 rotates after the outer plate 2 and inner plate 1 slide. This is because the bottom of the adjusting plate 15 has an overlapping groove 16, and a cylinder is provided above the inner plate 1, extending to the center of the overlapping groove 16 (as shown in the instruction manual). Figure 5As shown), a small piece extends laterally inward and overlaps the overlapping groove 16. As the outer plate 2 moves towards the inner plate 1, the adjusting plate 15 rotates first, causing the two sets of ventilation holes to misalign, achieving a complete blockage. Because the overlapping groove 16 is an arc-shaped and straight design, pressing first causes the adjusting plate 15 to rotate, and finally the rotating plate remains stationary, achieving the effect of blocking the ventilation holes. Finally, the positioning strip 17 of this solution is introduced. The positioning strip 17 is rotatably set on the inner plate 1, and one of them also has a small torsion spring. The function of the small torsion spring is also to make the positioning strip 17 rotate. The position bar 17 can be rotated to reset, and a screw hole is provided on the surface of the outer plate 2. A threaded cap 18 is threaded onto the surface of the screw hole. The threaded cap 18 conceals the pressing post 19. The pressing post 19 is slidably disposed on the surface of the outer plate 2, and a pressing spring 20 is located below it for pressing and resetting. A contact post 21 is rotatably disposed at the bottom of the pressing post 19. A contact groove 22 is provided on the outer side of the contact post 21. The surface of the contact groove 22 overlaps with the pressing post 19 (the overlapping principle is the same as the overlapping groove 16 on the middle of the inner plate 1 and the adjusting plate 15, as shown in the instruction manual). Figure 5 As shown, the bottom of the pressing column 19 also has a horizontally extending circular block that overlaps with the surface of the contact groove 22. (This is from the instruction manual.) Figure 3(The part was cut in half, so it is not shown.) The bottom of the contact post 21 is circular, but there are notches on both sides. When there are notches, the positioning strip 17 cannot hook onto the bottom of the contact post 21. According to this design, in order to facilitate the removal of the inner plate 1, the threaded cap 18 is removed. Then, the outer plate 2 is pressed first. As mentioned above, the horizontal block 12 needs to be pulled to rotate. In order to fix the outer plate 2 and the inner plate 1, the pressing post 19 is continuously pressed, so that the pressing post 19 rotates 90 degrees, offsetting the notch and contacting the top of the positioning strip 17. At this time, the top of the positioning strip 17 will overlap with the bottom of the contact post 21. At this time, the inner plate 1 is pulled out while pressing the pressing post 19 to complete the disassembly. After disassembly, only Pressing the pressing post 19 again rotates it 180 degrees, causing the other notch to reach the top of the positioning strip 17. Since the positioning strip 17 cannot hold the notch, the outer plate 2 is reset, thus achieving disassembly. Installation is also very convenient; simply press the inner plate 1. The outer plate 2 is slidably mounted on the upper surface of the inner plate 1. A mounting base 3 is located on one side of the inner plate 1, and a fixing mechanism is also located on one side. The fixing mechanism includes a fixing block 4, an insertion block 5, and a rotating strip 6. The fixing block 4 is slidably mounted on one side of the inner plate 1, and the insertion block 5 is slidably mounted on the edge of the inner plate 1. The rotating strip 6 is rotatably mounted on one side of the inner plate 1, with its top overlapping... There is a fixed block 4, an insertion block 5 overlapping the bottom of the rotating bar 6, a return spring 7 on one side of the rotating bar 6, an extension bar 8 integrally formed on the lower surface of the outer plate 2, a locking block 9 slidably disposed on one side of the fixed block 4, a buffer spring 10 disposed between the fixed block 4 and the locking block 9, a slot 11 disposed above the mounting base 3, a horizontal block 12 rotatably disposed on one side of the insertion block 5, a holding spring 13 disposed on one side of the horizontal block 12, an insertion port 14 opened on the upper surface of the mounting base 3, an adjusting plate 15 rotatably disposed on the upper surface of the outer plate 2, an overlapping groove 16 opened at the bottom of the adjusting plate 15, an inner plate 1 overlapping the surface of the overlapping groove 16, a positioning bar 17 rotatably disposed on the upper surface of the inner plate 1, and the outer plate 2 The upper surface of the inner plate 1 is threaded with a threaded cap 18. The upper surface of the outer plate 2 is slidably provided with a pressing post 19. A pressing spring 20 is provided between the pressing post 19 and the outer plate 2. The lower surface of the outer plate 2 is rotatably provided with a contact post 21. A contact groove 22 is opened on the side of the contact post 21. The pressing post 19 overlaps on the surface of the contact groove 22. A support structure is provided between the inner plate 1 and the outer plate 2. The support structure includes a first strip 23 and a second strip 24. The top of the first strip 23 is rotatably provided with the outer plate 2. The bottom of the first strip 23 is rotatably provided with the second strip 24. The bottom of the second strip 24 is rotatably provided with the inner plate 1. A support spring 25 is provided on one side of the second strip 24. A ventilation hole is opened on the upper surface of the adjusting plate 15.
