Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example: Please see Figures 1-5 The rear interior assembly of the agricultural machinery cab includes a base 1 and multiple upright beams 11. The upright beams 11 are fixed around the top of the base 1. A top beam 12 is provided between the tops of the multiple upright beams 11. A top cover 121 is provided on the top of the top beam 12. A front panel 2 and a rear panel 3 are also provided on the top of the base 1. The front panel 2 and the rear panel 3 are respectively located on both sides of the upright beams 11. A notch 32 is provided on the rear panel 3. Bushings 33 are symmetrically arranged on both sides of the notch 32.

[0020] In this embodiment, specific reference is made. Figure 1 , Figure 2 as well as Figure 3The cab includes a base 1 and multiple vertical beams 11. The vertical beams 11 are fixed around the top of the base 1. The top beam 12 connects the top of each vertical beam 11 and covers the top cover 121 to form an overall frame structure. The front bulkhead 2 is the front main enclosure of the cab, and the rear bulkhead 3 constitutes the rear structure of the cab. The rear bulkhead 3 and the front bulkhead 2 are both located between multiple vertical beams 11. The bottom of the rear bulkhead 3 contacts the base 1, and the top of the rear bulkhead 3 contacts the top cover 121. There is a window at the top of the rear bulkhead 3 and a notch 32 at the bottom of the rear bulkhead 3. The rear window 31 is located above the notch 32. The notch 32 on the rear bulkhead 3 facilitates cleaning of the interior of the cab or facilitates the operator to inspect and maintain the mechanical parts inside the cab.

[0021] The slide rail 5 has symmetrical rotating shafts 51 on both sides. The rotating shafts 51 are rotatably connected to the bushings 33. The slide rail 5 is embedded in the notch 32 and rotatably connected to the bushings 33, so that the slide rail 5 can rotate around the bushings 33 in the notch 32. Mounting plate 4, the size of which is adapted to the notch 32, is slidably mounted in slide rail 5, and positioning components for fixing position are symmetrically arranged on both sides of mounting plate 4.

[0022] In this embodiment, specific reference is made. Figure 4 as well as Figure 5 The slide rail 5 is specifically U-shaped and is specifically designed to fit the lower end face of the notch 32. The slide rail 5 supports the mounting plate 4 and guides its sliding. A rotating shaft 51 is symmetrically arranged on both sides of the slide rail 5. The rotating shaft 51 is rotatably connected to the bushing 33 on the rear panel 3, allowing the slide rail 5 to rotate around the bushing 33 at the notch 32. The mounting plate 4's specific function is to close the notch 32 and achieve a sealed protection for the interior of the cab. A handle 8 is provided on the mounting plate 4, located on the outside of the mounting plate 4. The mounting plate 4 can slide horizontally along the notch 32 via the slide rail 5. The handle can be gripped when maintenance is required. 8. The rotating shaft 51 rotates within the bushing 33, causing the slide rail 5 and mounting plate 4 to flip and open together. This causes the slide rail 5 to flip the mounting plate 4 outward. At this time, the slide rail 5 is in an outward flipped state, and the mounting plate 4 unfolds accordingly. It can be pulled out from the slide rail 5 for easy inspection and cleaning of the cab interior. During installation, the mounting plate 4 is aligned with the slide rail 5 and pushed in until it is locked by the positioning component. Then, the slide rail 5 is flipped to reset the rotating shaft 51, and the mounting plate 4 re-closes the notch 32, ensuring the sealing and structural stability of the cab interior. The entire process does not require disassembly of parts, making operation convenient and effectively improving maintenance efficiency.

[0023] Specifically, the slide rail 5 has a U-shaped structure, and positioning holes 52 are provided on the inner walls of both sides of the slide rail 5. The positioning component includes a ball 41 and a spring 42. The ball 41 is elastically installed on both sides of the mounting plate 4 by the spring 42, and the ball 41 is adapted to the positioning hole 52.

[0024] In this embodiment, specific reference is made. Figure 5 and Figure 6 Specifically, the positioning method of the mounting plate 4 is described. Positioning holes 52 are provided on the inner walls of both sides of the slide rail 5, that is, the two sides of the U-shaped slide rail 5. The inner side is the side that contacts the mounting plate 4. The positioning holes 52 are located at a preset position on the inner wall of the slide rail 5. When the mounting plate 4 slides along the slide rail 5 until it is fully embedded in the notch 32, the ball 41 is inserted into the positioning hole 52 under the elastic force of the spring 42, thereby realizing the positioning and fixing of the mounting plate 4.

[0025] Specifically, the rear panel 3 has a positioning block 6 on its back, and the positioning block 6 has a magnetic female block 61. The mounting plate 4 has an insert block 62 that matches the positioning block 6 on its back, and the insert block 62 has a magnetic female block 63 that cooperates with the magnetic female block 61.

[0026] In this embodiment, specific reference is made. Figure 4 and Figure 5 The positioning block 6 on the back of the rear panel 3 is used to limit the displacement of the mounting plate 4 in the closed state and prevent excessive flipping. When the mounting plate 4 is closed, the insert block 62 is inserted into the positioning block 6, and the magnetic female block 61 and the magnetic male block 63 on the insert block 62 attract each other to achieve auxiliary fixation. When it is necessary to open, hold the handle 8 and pull the mounting plate 4 outward. The magnetic attraction is overcome, the insert block 62 is disengaged from the positioning block 6, and then the slide rail 5 can be flipped to complete the opening action, which is convenient for flipping operation.

[0027] Specifically, a ventilation grille 7 is provided in the middle of the mounting plate 4, and the ventilation grille is detachably fixed to the mounting plate 4.

[0028] In this embodiment, the ventilation grille 7 is bolted to the mounting plate 4. The ventilation grille 7 enables air circulation during the operation of the cab. In some special operating conditions, the ventilation grille 7 can be replaced with a sealing cover to enhance the sealing performance of the cab and adapt to the operating requirements in high dust or humid environments, with high adaptability.

[0029] Specifically, a first side panel 15 and a second side panel 16 are respectively provided on both sides of the upright beam 11. A first side window 151 is provided on the first side panel 15, and a second side window 161 is provided on the second side panel 16. A support beam 13 is provided in the middle of the second side panel 16, and a door 14 is hinged to one side of the support beam 13.

[0030] In this embodiment, the first side panel 15 is the right side panel of the cab, and the second side panel 16 is the left side panel of the cab. The support beam 13 is vertically arranged in the middle of the second side panel 16. Specifically, the first side window 151 on the first side panel is a single piece of glass structure, providing a wide field of vision and facilitating the driver's observation of the right side. A door 14 is provided on the second side panel on the right side, and the second side window 161 is located above the second side panel 16. While ensuring a clear view on the left side, it is designed as a single-sided opening structure.

[0031] The principle of this utility model is as follows: When it is necessary to close the notch 32, first rotate the slide rail 5 to an inclined state, push the mounting plate 4 along the slide rail 5 until the ball 41 is inserted into the positioning hole 52 to complete the positioning. Under the action of the spring 42, the ball 41 automatically locks the positioning hole 52 to ensure that the mounting plate 4 is stable and does not loosen. Push the handle 8 to make the rotating shafts 51 on both sides of the slide rail 5 rotate in the rotating sleeve, causing the slide rail 5 and the mounting plate 4 to flip together to the horizontal position. At this time, the mounting plate 4 completely covers the notch 32, the insert block 62 is inserted into the positioning block 6, and the magnetic mother block 61 and the magnetic mother block 63 on the insert block 62 attract each other to achieve auxiliary fixation.

[0032] When it is necessary to open, hold the handle 8 and pull the mounting plate 4 outward to overcome the magnetic attraction and make the insert 62 disengage from the positioning block 6. Then push the slide rail 5 to flip to the tilted state, pull the mounting plate 4 out along the slide rail 5, and the ball 41 disengages from the positioning hole 52 to complete the opening action. The operation is simple, stable and reliable, and suitable for operation scenarios with frequent opening.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
