Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a net bale placing device for a round grass bale baler and a baler. Background Art

[0002] In my country's unique cropping environment, baling operations are affected by the seasons, resulting in short operating times. Improving efficiency within this limited operating season has become a pressing issue for baler manufacturers. Improving efficiency, stability, and quality reliability are currently the biggest challenges.

[0003] The biggest problem with existing round hay balers during operation is the stability of the net wrapping system, which directly affects the quality of hay or straw bales.

[0004] Existing methods for securing the net bale on round hay balers include a pin-type system and a steel pipe frame with a mesh press. For the pin-type system, a nylon mesh cover is placed inside the paper tube hole in the center of the net bale. A pin is then inserted into the cover, with one pin fixed and the other adjustable. Bearings are required within the pin mechanism to ensure flexible rotation of the net bale tube during operation. However, this mechanism is complex and requires high precision, resulting in a high risk of damage. To replace the net bale, the adjustable pin must be loosened, the nylon mesh covers removed, and placed inside the new net bale tube. The new net bale is then secured to the two pins, while the adjustable pins must be manually adjusted. This makes replacing the net bale time-consuming and labor-intensive, resulting in low efficiency. 2. The effect of using steel pipes to support the net is good, but when replacing a new net bundle, the steel pipe needs to be passed through the paper tube of the net bundle, and then the net bundle with the steel pipe is fixed to the support frames on both sides. There are pin holes at both ends of the steel pipe. After inserting the pin shaft, the steel pipe is prevented from rotating. A nylon block is set between the steel pipe and the net bundle. The nylon block rotates with the net bundle, so replacing a new net bundle is time-consuming and laborious. Utility Model Content
