Description

Technical Field

[0001] The utility model relates to the technical field of harvesters, in particular to a crawler-type harvester chassis with a mud scraper. Background Art

[0002] Crawler harvesters have good adaptability due to their special walking devices, and can complete harvesting operations whether working in dry fields or in relatively wet fields. When there is water accumulation in the field or the soil is humid, wheeled harvesters cannot enter the field to work, and the wheels are easy to sink into the field. In contrast, crawler harvesters, with their stable performance and excellent adaptability, avoid such situations, and can help farmers complete the seasonal rush harvest in time to ensure that farmers complete the harvesting operation.

[0003] Since the working conditions of the harvester in the field are more complicated, especially when working in muddy or wet fields, when the crawler harvester is harvesting, mud and debris will stick to the supporting wheels. When there is a lot of sticky mud and debris, the energy consumption of the harvester will increase, the crawler operation will be blocked and stuck, affecting the forward operation of the walking device, and the crawler may even slip, reducing the service life of the crawler, resulting in major accidents such as the machine being paralyzed in the field. In addition, the cleaning of mud and debris needs to be done manually, which is more cumbersome and greatly wastes time and labor. Utility Model Content

To this end, one purpose of the utility model is to provide a crawler harvester chassis with a scraper, the scraper on the chassis can scrape off the mud and debris stuck on the supporting wheels, improve the adaptability of the harvester, and ensure the normal forward operation of the harvester.

[0005] To solve the above technical problems, the technical solution provided by the utility model is as follows: a crawler harvester chassis with a scraper comprises a frame and a crawler walking device, the crawler walking device is connected through the frame, the crawler walking device comprises a driving wheel, a guide wheel, a supporting roller, a track roller and a crawler, the driving wheel, the guide wheel, the track roller and a plurality of the supporting rollers are installed on the frame, the track is wrapped around the outside of the driving wheel, the guide wheel, a plurality of supporting rollers and the track roller, the rotation direction of the supporting roller is the working direction, the supporting rollers are grouped in three, a scraper is provided between two adjacent supporting rollers in a group, the scraper is fixedly connected to the frame at a certain angle, and the two ends are facing opposite to the working direction.

[0006] Preferably, the scraper blade has an "L"-shaped cross section and is bilaterally symmetrical.

[0007] Preferably, the scraper blade is divided into a short side of the scraper blade and a long side of the scraper blade, both of which are planes, and the two sides are vertically connected to each other.

[0008] In order to connect the scraper blade to the frame, the scraper blade has a short side through hole on the short side, and the frame has a corresponding hole, the two holes are aligned, and the two holes are fixedly connected by bolts.

[0009] In order to scrape off the dirt and debris adhering to the supporting wheels, the long side of the scraper blade is in direct contact with the dirt and debris.

[0010] In order to enable the supporting wheels to operate normally, a certain gap is left between the scraper blade and the supporting wheels.

[0011] After adopting the above structure, the utility model has the following advantages:

[0012] The present application has the characteristics of simple structure, easy installation and disassembly, not easy to damage, reliable operation and easy implementation by arranging a scraper plate between two supporting wheels. When the crawler harvester is working, the supporting wheels rotate, and the rotation direction of the supporting wheels is the working direction. The two ends of the scraper plate obliquely installed on the frame are oriented opposite to the working direction. The mud and debris adhered to the supporting wheels will scrape the scraper plate as the supporting wheels rotate. The scraper plate automatically scrapes off the mud and debris on the supporting wheels to ensure that too much mud and debris will not adhere to the supporting wheels, thereby improving the stability and support of the supporting wheels, ensuring the normal operation of the supporting wheels, reducing energy consumption, improving the performance of the harvester, preventing the occurrence of track blocking, jamming and slipping and falling off, increasing the life of the track, reducing the trouble caused by manual cleaning, saving harvesting time and reducing labor intensity.

[0013] The above summary is for the purpose of description only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the utility model will be readily apparent by reference to the accompanying drawings and the following detailed description.
