DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0022] like Figure 1 to Figure 6 As shown, a shock-absorbing and sealed harvester cab includes a cockpit and a shock-absorbing structure. The cockpit includes a cabin body 6, a sealing strip 9 and a cabin door 2. The cabin body 6 is provided with a door frame and a plurality of glass windows. The door frame is used to install the cabin door 2. The plurality of glass windows ensure a good field of vision in the cab, facilitating the driver's work.

[0023] In order to achieve sealing of the glass window, a sealing strip 9 is provided at the connection between the glass window and the cabin body 6 to prevent dust from entering the cab through the glass window.

[0024] The hatch door 2 is arranged in the door frame of the cabin body 6, and the hatch door 2 includes a first sealing plate 1, an outer door panel 14, a second sealing layer 7 and an inner door panel 10. The first sealing plate 1, the outer door panel 14, the second sealing layer 7 and the inner door panel 10 are stacked in sequence, and the first sealing plate 1 covers the outer door panel 14. The cross-section of the first sealing plate 1 is larger than that of the outer door panel 14. The cross-sections of the outer door panel 14, the second sealing layer 7 and the inner door panel 10 are the same, which is convenient for forming a sealing structure to prevent dust from entering the cab.

[0025] The first sealing plate 1 includes a rubber sheet and a sealing plate. The rubber sheet wraps the sealing plate. After the hatch 2 is closed, the first sealing plate 1 is tightly fitted to the surface of the cabin body 6 to form a first layer of sealing structure to prevent dust from entering the cab.

[0026] A second sealing layer 7 is provided between the outer door panel 14 and the inner door panel 10. The second sealing layer 7 is a rubber sealing layer, i.e., a plate structure made of rubber. The second sealing layer 7 is tightly fitted with the inner edge of the door frame in the cabin body 6 to form a second sealing structure to prevent dust from entering the cab from the cabin door 2. Figure 1 , Figure 3 and Figure 4 shown.

[0027] The shock-absorbing structure can achieve shock absorption of the cockpit. The shock-absorbing structure includes a base 8, a hydraulic shock-absorbing device 4, a bottom plate 5 and a shock-absorbing pad 3. A plurality of hydraulic shock-absorbing devices 4 are arranged above the base 8. Specifically, there are four hydraulic shock-absorbing devices 4. A hydraulic shock-absorbing device 4 is arranged at each of the four corners of the base 8. The hydraulic shock-absorbing device 4 is connected and fixed to the bottom plate 5 at the top. The bottom plate 5 is located below the cabin 6. The cabin 6 is connected to the bottom plate 5, and the cabin 6 can be subjected to primary shock absorption.

[0028] The shock-absorbing pad 3 is arranged between the bottom plate 5 and the cabin body 6 to perform secondary shock absorption on the cabin body 6. The shock-absorbing pad 3 includes an upper pad 15, a lower pad 13, a shock-absorbing block 11 and a buffer body 12. A plurality of shock-absorbing blocks 11 are evenly distributed above the upper pad 15. The plurality of shock-absorbing blocks 11 are all triangular prism structures, which can better absorb the force generated by the vibration. The upper pad 15 and the lower pad 13 are spaced apart from each other. The edges of the upper pad 15 are connected to the lower pad 13. A cavity is formed between the upper pad 15 and the lower pad 13. A plurality of buffer bodies 12 are evenly distributed in the cavity. Some of the buffer bodies 12 are cylindrical, which can further enhance the shock absorption effect. Figure 5 and Figure 6 shown.

[0029] In actual application, when the harvester passes over uneven ground, the vibration generated is first absorbed by the hydraulic shock absorbing device 4 in the shock absorbing structure, and then the shock absorbing block 11 above the shock absorbing pad 3 will alleviate the vibration, and the buffer body 12 in the cavity of the shock absorbing pad 3 will further fully absorb the generated vibration. The shock absorbing pad 3 will perform secondary shock absorption after the hydraulic shock absorbing device 4 absorbs the shock to ensure the stability of the cab and greatly reduce the vibration.

[0030] When the driver drives the harvester to perform harvesting operations, the glass window of the cab is closed, and the sealing strip 9 forms a sealing layer at the connection between the glass window and the cabin body 6 to prevent dust from entering the cab through the glass window. After the cabin door 2 is closed, the first sealing plate 1 fits tightly against the outer shell of the cabin body 6 to prevent most of the dust from entering the cab through the cabin door 2, and the second sealing layer 7 fits tightly against the inner edge of the door frame of the cabin body 6 to form a secondary seal to ensure that dust does not enter the cab.

[0031] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
