Description
Technical Field
[0001] The utility model relates to the field of balers, in particular to a pick-up device for a baler. Background Art
[0002] With the rapid development of animal husbandry, the demand for the quantity of forage grass is increasing day by day. Natural forage grass can no longer meet the needs of the development of animal husbandry. Therefore, corn straw and wheat straw have gradually become the forage for animal husbandry in some areas. Mechanized harvesting of forage grass is a common and very mature method when harvesting corn straw and wheat straw. There are also many types of harvesting machines. The most commonly used mechanized harvesting equipment is a baler.
[0003] The existing straw baler pick-up generally falls into two types: with a cam and without a cam. The existing cam-type baler has a complex structure, high assembly requirements, a high damage rate, and is difficult to repair; for the existing camless-type baler pick-up, the spacing between the spring teeth is large, the number is small, the picking efficiency is low, the included angle between the spring teeth and the guard plate is small, and a guard ring must be installed to protect the spring teeth. After installing the guard ring, when the spring teeth are damaged, the guard ring needs to be disassembled first and then the spring teeth are replaced. The guard ring is difficult to disassemble, the repair efficiency is low, and for the structure without a cam and without a guard ring, the included angle between the spring teeth and the guard plate is too small, which is easy to clamp grass. When encountering relatively hard straw such as corn straw or relatively thick straw, the spring teeth are particularly easy to be damaged, the service life of the spring teeth is low, the failure rate is high, and frequent replacement of the spring teeth will make it difficult to operate continuously. In addition, at present, the number of rows of spring teeth of the baler pick-up is small, the spacing is large, and the quantity is low, resulting in limited picking efficiency and inability to meet the user's demand for rapid operation during the limited operation season.
