Description

Technical Field

[0001] The invention belongs to the technical field of agricultural and animal husbandry machinery, and in particular relates to a forage preparation device with adjustable gaps of straight-toothed steel rollers for harvesting natural forage or artificially planted forage. Background Art

[0002] To reduce forage losses during harvest and accelerate forage stalk drying, a mower and conditioner is essential. This invention is part of a mower and conditioner system and is applicable to traction-type, rotary, and self-propelled rotary mowers. Compared to existing forage conditioners on the market, this invention features adjustable steel roller gaps, strong gripping and crushing capabilities, significant crushing effects, high efficiency, and high reliability. Summary of the Invention

[0003] The object of the present invention is to provide a forage conditioning device with adjustable gap of straight tooth steel rollers, which can condition and collect cut forage on natural grassland or artificial grassland.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] The forage conditioning device with adjustable gaps between spur-tooth steel rollers mainly includes a frame, an adjustment mechanism, spur-tooth steel rollers, an upper baffle, a bearing seat plate, a left baffle, and a right baffle. The adjustment mechanism is placed on the frame, and the two ends of the adjustment mechanism are hinged to the left and right sides of the frame respectively. The bearing seat plate is placed on the left side of the frame and is fixed to the frame. Two spur-tooth steel rollers are placed on the inner side of the frame, one above and one below. The tooth tops and tooth roots of the upper and lower spur-tooth steel rollers are meshed with each other. The two ends of the upper spur-tooth steel roller are hinged to the bearings at both ends of the adjustment mechanism respectively. The left end of the lower spur-tooth steel roller is hinged to the bearing of the bearing seat plate, and the right end is hinged to the bearing on the right side of the frame. The upper baffle is placed at the rear of the frame, and the two ends are hinged to the two sides of the frame respectively. The left baffle is placed at the left rear of the frame and is fixed to the frame. The right baffle is placed at the right rear of the frame and is fixed to the frame.

[0006] The present invention is used in conjunction with a rotary harvesting table. Before operation, the position of the upper spur-tooth steel roller is adjusted by adjusting the adjustment points on the left and right sides of the adjustment mechanism connected to the frame, thereby adjusting the gap between the upper and lower spur-tooth steel rollers to meet the forage preparation requirements. The upper baffle limit point is selected appropriately based on the forage growth density and plant height to meet the forage strip harvesting requirements. During operation, the tractor transmits power through two counter-rotating drive shafts, driving the upper and lower spur-tooth steel rollers to rotate in opposite directions, preparing and collecting the forage continuously fed from the front end into strips of a certain width.
