Description

A cotton topping machine frame with adjustable line spacing

technical field

The utility model relates to a cotton topping machine, in particular to a cotton topping machine frame.

Background technique

At present, the research and development of cotton topping machinery is rapid, and there are many types of topping machines. As the skeleton of the whole machine, the topping machine frame has different types according to different requirements, so there are few research results on the topping machine frame. The topping machine frame bears the main force when it is working, and is also used for fixing and supporting other components. Most of the components on the topping machine, such as: traction suspension frame, power assembly, topping device spindle, topping device, lifting hydraulic cylinder, hinged ground wheel, etc., are directly connected to the frame. During the working process, the profiling effect formed by the power traction of the tractor and the jumping of the hinged ground wheel during the forward process directly affects the topping effect of the whole machine. Therefore, the requirements for the frame in the design of the whole machine are relatively high. In particular, Xinjiang cotton has various planting patterns such as 68+8, 30+60, and 66+10cm. The existing topping machine frames are fixed welded parts, the overall size is fixed, and the versatility is poor. They only conform to a single planting pattern. It cannot be adjusted according to different planting patterns and ground conditions during field operations. Therefore, the frame of the existing topping machine cannot fully meet the topping process requirements of different row spacings.

On the middle angle iron of the slide rail 7, the power spindle of the topping device is installed in the bearing housing 19, and parts such as the topping device are installed on the power spindle of the topping device and the row spacing adjustment slide rail 7. The disassembly and spacing adjustment of the slide rail 7 is adjusted to meet the operation needs of the topping machine, thereby realizing the significance of the adjustable row spacing cotton topping machine frame.

During the working process, the shaft-type traction hanger plays an important role in longitudinal traction and balancing lateral runout of the overall frame. The tractor is connected with two suspension ears 8, and the two clamping plates 14 on the shaft-type traction suspension frame are stuck on the main frame body 5 for traction in the forward direction. The sleeve 15 of the shaft-type traction suspension frame and the internal structure of the main frame body 5 Both ends of the power input shaft 24 are sequentially socketed with a tapered roller bearing 17, a shaft sleeve 16, and a tapered roller bearing 17. Both ends of the sleeve 15 are sealed with bearing end caps 21, and the power is transmitted through the power input shaft 24 in the sleeve. to the gearbox on the frame. Such a structure has only fixed the front and rear positions of the traction suspension frame and the main frame 5, and both can rotate at a small lateral angle with the power input shaft 24 as the axis, because the rotating shaft type traction suspension frame and the main frame body 5 are hinged, Effectively avoid interference during high-speed operation.

The installation number of the row spacing adjusting slide rails 7 can be selected according to the specific requirements of the operation, and the spacing of the row spacing adjusting slide rails 7 can be adjusted according to the specific row spacing.

The beneficial effect of the utility model is that: the two clamping plates at the upper end of the rotating shaft type traction suspension frame are stuck on the main frame body, and the power of the tractor is transmitted to the main frame body and the gearbox through the rotating shaft type traction suspension frame and the power input shaft. During the working process, the articulated shaft-type traction suspension frame and the main frame body can rotate at a small lateral angle to avoid interference between components; according to different ground conditions and cotton heights, the adjustable support can be adjusted by rotating the screw thread to meet the work requirements. The overall height of the frame, the articulated articulated ground wheel and the threaded adjustable support can copy the ground; the flexible adjustment and disassembly of the distance between the row spacing adjustment slide rails can be applied to different planting modes and working row spacing of the topping machine, and improve cotton betting. The versatility of the top machine.
