[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a four-row cotton box valve structure for a cotton harvester, including a combined valve 1 and an installation component. The installation component includes an installation plate 2, which is "E" shaped. The combined valve 1 is installed on the rear side of the installation plate 2 via a plug-in mechanism. The plug-in mechanism includes a vertical rod 4, a plug rod 5, and a magnetic suction plate 6. The plug rod 5 is symmetrically slidably disposed inside both ends of the installation plate 2, and symmetrically fixedly disposed on one side of the magnetic suction plate 6. The middle end of the installation plate 2 is provided with... A limiting mechanism 7 is provided, which includes a pressure rod 19, a horizontal plate 23, and a protruding rod 24. A limiting hole 22 is opened inside one end of the vertical rod 4, and the protruding rod 24 is engaged inside the limiting hole 22. By pushing the magnetic suction plate 6 and the insertion rod 5, the mounting plate 2 and the vertical rod 4 can be inserted and limited, which facilitates the quick installation and fixing of the combination valve 1. By pulling and adjusting the magnetic suction plate 6 and the insertion rod 5, the combination valve 1 can be quickly disassembled, which is convenient for its maintenance or replacement, and it is highly practical.
[0023] In this embodiment, the combined valve 1 is provided with the following components from left to right: return oil pipe 11, tilting cylinder oil passage 12, extension cylinder oil passage 13, side door oil passage 14, compactor motor oil passage 15, vent hood oil passage 16, ground motor oil passage 17, and box door motor oil passage 18. An oil inlet 10 is fixedly provided inside one end of the combined valve 1, and an oil inlet pipe is fixedly provided at one end of the oil inlet 10. The compactor motor oil passage 15, ground motor oil passage 17, and box door motor oil passage 18 all include two-position two-way solenoid valves. Oil pipes are fixedly provided at both ends of the two-position two-way solenoid valves, and the bottom oil pipe is fixedly connected to the oil inlet pipe. The return oil pipe 11 is L-shaped, and an oil outlet 9 is fixedly connected to one side of the bottom end of the combined valve 1 at the bottom end, which facilitates the control of the cotton box, thereby completing the compaction, packing, and discharge operations of the cotton inside the cotton box.
[0024] In this embodiment, the vertical rods 4 are symmetrically fixed on both sides of the front end of the combination valve 1. First insertion holes 8 are symmetrically opened inside both ends of the vertical rods 4. The vertical rods 4 are installed on both sides of the middle end of the mounting plate 2 and are in close contact. A second insertion hole 21 is opened inside the middle end of the mounting plate 2 corresponding to the position of the first insertion hole 8. The horizontal plate 23 is horizontally fixed on the rear side of the bottom end of the pressure rod 19. The horizontal plate 23 is slidably positioned at the bottom of the upper second insertion hole 21. An installation groove 20 is opened inside the middle end of the mounting plate 2. The pressure rod 19 is slidably positioned inside the installation groove 20. A spring is fixedly installed between the bottom end of the pressure rod 19 and the installation groove 20. One end of the insertion rod 5 is inserted into the first insertion hole. Inside the first insertion hole 8 and the second insertion hole 21, the mounting plate 2 is made of iron. A strong magnet is fixedly installed inside the magnetic suction plate 6. Fixing holes 3 are symmetrically opened at both ends of the mounting plate 2. After the insertion rod 5 is inserted into the first insertion hole 8 and the second insertion hole 21, the vertical rod 4 can be fixed, which facilitates the fixing of the combination valve 1 and the mounting plate 2. The magnetic suction plate 6 is magnetically fixed to both ends of the mounting plate 2 by the strong magnet, which can prevent the insertion rod 5 from moving. At the same time, the pressure rod 19 is in the top position under the elastic force of the spring, and the horizontal plate 23 drives the protruding rod 24 under the action of the pressure rod 19, so that the protruding rod 24 is inserted into the corresponding limiting hole 22, which facilitates the secondary fixing of the insertion rod 5 and can improve the stability of the limiting mechanism 7.
[0025] When using the four-row cotton box valve structure of this cotton harvester, the mounting plate 2 is fixedly installed on the cotton box valve mounting position of the four-row cotton harvester through the fixing hole 3. The three ends of the combination valve 1 are in contact with the mounting plate 2, so that the vertical rod 4 is set on both sides of the middle end of the mounting plate 2 and is in contact. The first insertion hole 8 and the second insertion hole 21 are opposite each other. The insertion rod 5 is inserted into both ends of the mounting plate 2, and one end of the insertion rod 5 is inserted into the inside of the first insertion hole 8 and the second insertion hole 21. At this time, the insertion rod 5 with the limiting hole 22 is set above the other one without the limiting hole 22. The magnetic suction plate 6 is attached to both ends of the mounting plate 2 and magnetically fixed by the magnetic attraction of the strong magnet, which facilitates the limiting of the insertion rod 5. Before inserting the insertion rod 5, press the pressure rod 19 first. The pressure rod 19 drives the horizontal plate 23 and the convex rod 24 to move downward and compress the spring. The insertion rod 5 is inserted into the second... After inserting into the socket 21, release the pressure rod 19. Under the spring force, the pressure rod 19 moves upward, and through the horizontal plate 23, it moves the protruding rod 24 upward, inserting the protruding rod 24 into the corresponding limiting hole 22. This facilitates secondary limiting of the insert rod 5, improving the stability of the insert rod 5 and the magnetic suction plate 6, and facilitating the quick installation and fixation of the combination valve 1. Pressing the pressure rod 19 separates the protruding rod 24 from the limiting hole 22, and by pulling the magnetic suction plate 6 and the insert rod 5, it facilitates the quick disassembly of the combination valve 1, making it convenient for maintenance and replacement, and improving the practicality of the structure. After the pressure rod 19 moves to the top, the spring is also in a compressed state, so that the pressure rod 19 continuously receives the spring force, preventing the structure from being disengaged from the combination valve 1 due to vibration.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
