Description

Technical Field

[0001] The utility model relates to the technical field of cabs, and specifically to a cab for a plant protection machine. Background Art

[0002] The plant protection machine is a machine used for rural plant protection. With the mechanization of agriculture, it is increasingly used in rural agriculture. The cab is the control room that controls the plant protection machine to achieve plant protection and transportation functions. When the plant protection machine is working, the windshield in the cab is often easily contaminated with dust, resulting in obstruction of the driver's vision.

[0003] The existing cleaning work for the windshield in the cab of the plant protection machine is: soaking a wiping towel in a cleaning liquid, then wiping the windshield, and then wiping the cleaning liquid on the windshield again with a dry towel.

[0004] Although this method can clean the windshield in the cab, it still has the following disadvantages: 1. It is time-consuming and laborious to rely on the driver or the co-driver to clean; 2. The existing windshield is often tilted for a wider field of view, with a higher windshield height at the end close to the cab and a lower windshield height at the end away from the cab. In this way, the cleaning liquid set on the windshield is easy to drip into the cab, affecting the cleanliness of the cab. Utility Model Content

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 2 to Figure 6As shown, this embodiment proposes a cab of a plant protection machine, and its structure includes a main frame 1. Among them, the mounting frame 2 in this embodiment is arranged on the main frame 1, the windshield 3 is fixedly arranged on the mounting frame 2, and the first rotating structure and the second rotating structure are arranged between the two sides of the mounting frame 2 and the main frame 1, which are used to turn the mounting frame 2 toward the main frame 1 or to make the mounting frame 2 rotate away from the main frame 1. The driving structure is arranged between the main frame 1 and the rotating structure, which is used to drive the rotating structure to rotate, and the cleaning member 53 is arranged on the mounting frame 2, which is used to clean the windshield 3. The control structure is arranged between the mounting frame 2 and the cleaning member 53, which is used to control the movement of the cleaning member 53 relative to the mounting frame 2.

[0030] The cross section of the mounting frame 2 in this embodiment is a "U"-shaped structure, the mounting groove 21 is set in the center of the mounting frame 2, and the windshield 3 is fixed to the mounting groove 21 by bolts. This design is to remove and replace the windshield 3 by simply turning the bolts when the windshield 3 is damaged and needs to be replaced, which is more convenient.

[0031] The cleaning member 53 in this embodiment is also fixed with an elastic rubber layer near the windshield 3 to increase the contact area between the cleaning member 53 and the windshield 3, so that the windshield 3 can be cleaned more thoroughly. The water spray assembly 8 is fixedly arranged on the first mounting plate 51, and a plurality of water spray ports 81 are arranged on the water spray assembly 8, and the water spray ports 81 are directed to the windshield 3. The water spray assembly 8 in this embodiment can be provided with cleaning liquid and clean water inside. When cleaning, the cleaning liquid can be sprayed first for cleaning, and then the clean water can be sprayed to rinse the cleaning liquid, so that the windshield 3 can be cleaned more thoroughly.

[0032] The first rotating structure in this embodiment includes a rotating rod 9, which is fixed to the mounting frame 2 by bolt connection. The rotating member 11 is fixedly arranged on the main frame 1, and the other end of the rotating rod 9 is rotatably connected to the rotating member 11. The rotating rod 9 is at a certain angle to the mounting frame 2, and a gap is set between the rotating member 11 and the mounting frame 2. The first rotating structure and the second rotating structure have the same structure. This design is to rotate the rotating rod 9 to drive the mounting frame 2 to move away from the main frame 1, so that there is a certain gap between the mounting frame 2 and the main frame 1, so that when the cleaning liquid is used to clean the windshield 3, the cleaning liquid can directly slide into the gap and will not enter the interior of the cab.

[0033] The driving structure in this embodiment includes a telescopic member 4, the fixed end of the telescopic member 4 is rotatably connected to the top of the main frame 1, the rotating end 91 is arranged at the center of the rotating rod 9, and the telescopic end of the telescopic member 4 is rotatably connected to the rotating end 91. The telescopic member 4 in this embodiment is preferably a hydraulic cylinder or a cylinder. Among them, the hydraulic cylinder or the cylinder is the prior art, and this embodiment will not be repeated. The number of the telescopic members 4 in this embodiment is two, and they are respectively arranged on the first rotating structure and the second rotating structure. When in use, the telescopic members 4 need to be extended or retracted synchronously to keep the mounting frame 2 balanced at both ends when rotating.

[0034] The control structure in this embodiment includes a first mounting plate 51 and a second mounting plate 52. The first mounting plate 51 and the second mounting plate 52 are fixedly arranged at the upper and lower ends of the mounting frame 2. The first mounting plate 51 and the second mounting plate 52 are arranged parallel to each other, and the first screw rod 61 and the second screw rod 62 are respectively arranged at both ends of the first mounting plate 51 and the second mounting plate 52. The cleaning member 53 is threadedly connected with the first screw rod 61 and the second screw rod 62 at the same time. The first screw rod 61 and the second screw rod 62 are rotated to drive the cleaning member 53 to move, so that the cleaning member 53 moves more stably and can stop at any position of the windshield 3, and the position of the windshield 3 that needs to be wiped is repeatedly moved for targeted cleaning.

[0035] The synchronous belt 7 in this embodiment is arranged on the first mounting plate 51, and the synchronous belt 7 is rotatably connected with the first screw rod 61 and the second screw rod 62 at the same time, and the drainage groove 521 is arranged on the side of the second mounting plate 52 close to the mounting frame 2. The design of the drainage groove 521 allows the cleaning liquid to be discharged through the drainage groove 521, and the cleaning liquid will not remain in the mounting frame 2.

[0036] The working process of this embodiment is as follows: when it is necessary to clean the inside of the windshield 3, the telescopic parts 4 on the mounting frames 2 on both sides are first opened at the same time, so that the rotating rod 9 rotates and drives the mounting frame 2 to rotate away from the main frame 1, and a gap is generated between the mounting frame 2 and the main frame 1. Then, the water spray assembly 8 is opened to allow the water spray port 81 to spray water on the windshield 3. Then, by continuously switching the forward start and reverse start synchronous belt 7, the first screw rod 61 and the second screw rod 62 rotate at the same time, and drive the cleaning member 53 to move repeatedly on the windshield 3, so as to achieve wiping and cleaning of the windshield 3.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
