round baler

Abstract

In a roll baler (1), a roll shaping section (5) includes an endless transport unit (3) and a plurality of rollers (4). The endless transport unit (3) is provided to extend to a rear position beyond a lower end portion (B) of the roll forming section (5) below a rotation center (C). The plurality of rollers (4) are arranged in an arc form from a rear side of the endless transport unit (3). A crop transported to a rear end of the endless transport unit (3) is pressed against the rollers (4), is pushed up by rotation of the rollers (4), and is rotated by its own weight and rotation of the rollers (4) to form a small roll (71) in an initial state. Then, the roll (71) is increased in size by crops transported sequentially.

Description

technical field [0001] The present invention relates to a roll baler that picks up crops such as pasture and straw in the field and forms them into a cylindrical roll bale. Round baler that reliably forms round bales. Background technique [0002] use Figure 6 The configuration of a conventional general round baler will be described. [0003] exist Figure 6 Among them, reference numeral 101 is a pick-up unit for picking up crops in the field, which rotates a cylindrical rotating member disposed close to the ground, and picks up crops with rake teeth (タイン) provided on its outer periphery. In addition, reference numeral 102 is a conveyance part which conveys the crop picked up by this pick-up part 101 to the round bale forming part 103, and is comprised by the endless conveyance part, such as a belt. In addition, reference numeral 103 is a round bale forming part that forms a cylindrical round bale while rotating the crops conveyed by the conveying part. And, in the case ...

Problems solved by technology

However, the structure of the tightening rod type has such disadvantages: since the tightening chain on which the tightening rod is installed slides along the arc-shaped guide, a relatively large noise will be generated

However, with a roller structure, not only are there fewer points of contact between the crop and the roller, but the roller itself does not move like a take-up bar, so that, for example, if the crop contains a lot of moisture, there are cases where the crop will Sliding on the rollers in the entrance section of the round bale forming section, where the crop becomes lumps and the crop cannot advance and cannot be formed into a scroll-shaped round bale
