Classification unified harvesting-type cotton picker picking head and cotton picker

Abstract

The invention discloses a classification unified harvesting-type cotton picker picking head and a cotton picker. The classification unified harvesting-type cotton picker picking head is arranged in the front of a cotton picker headstock and comprises cotton picking rollers and grid plates. The body frame of the picking head is an auger groove cabin. The rear side of the auger groove cabin is provided with a discharging outlet and a docking device, and the front side of the auger groove cabin extends forwards to be in a comb shape. Baffles are arranged at the left side and the right side of the auger groove cabin. A transmission device is arranged outside the baffles. An auger roller is arranged inside the auger groove cabin. The cotton picking rollers are arranged at the positions, close to the front portion, of the inside of the auger groove cabin. The axis of each cotton picking roller is roughly parallel to the axis of the auger roller and is also roughly parallel to the axes of vehicle front wheels in the process of going straightly. Gaps are reserved between the cotton picking rollers and the auger roller in the radial direction. A cotton retreating device and a cotton collecting and conveying device are arranged on the upper portion of each cotton picking roller. A channel is formed from the bottom of each grid plate to the top face of a comb. Dividers are arranged at the front end of the auger groove cabin and located at the two axial sides of each cotton picking roller. A stem pulling device is arranged below the comb. By means of the classification unified harvesting-type cotton picker picking head and the cotton picker, the clean harvesting rate reaches 98% or above, cotton seeds can be harvested and collected in a classified mode, the cotton quality is guaranteed, and adaptability to the cotton planting mode is high.

Description

technical field [0001] The invention belongs to the technical field of cotton picking machinery. Background technique [0002] The existing mature cotton picking machine and cotton picking machine are represented by the horizontal cotton picking machine designed and produced by Deere and Case in the United States. The cotton picking drum of the horizontal cotton picking machine is vertically placed, and the picking spindle is level , this type of machine has high efficiency, precise production, and reliable work, but it may be that the original designer faced different specific environments or made different choices, so the horizontal cotton picker has several congenital deficiencies: First, picking The head is over-compressed on the cotton stem, and the picking spindle with all bare teeth is used, which promotes the excessive grasping of the picking spindle, resulting in a lot of impurities in the seed cotton, and the mixing of mature cotton and cotton with poor maturity, m...

[0002] The existing mature cotton picking machine and cotton picking machine are represented by the horizontal cotton picking machine designed and produced by Deere and Case in the United States. The cotton picking drum of the horizontal cotton picking machine is vertically placed, and the picking spindle is level , this type of machine has high efficiency, precise production, and reliable work, but it may be that the original designer faced different specific environments or made different choices, so the horizontal cotton picker has several congenital deficiencies: First, picking The head is over-compressed on the cotton stem, and the picking spindle with all bare teeth is used, which promotes the excessive grasping of the picking spindle, resulting in a lot of impurities in the seed cotton, and the mixing of mature cotton and cotton with poor maturity, making the micronaire value of machine-picked cotton unsatisfactory Second, there is a probability problem in the tangential flow interpenetration of the cotton picking cylinder, so it is often picked twice, resulting in large power loss, large mechanical wear, and high harvesting costs

Third, even if it is harvested twice, there will be a lot of ground cotton, hanging branch cotton and green peaches that cannot be recycled, causing a lot of waste; fourth, it is necessary to strictly follow the row spacing of 66+6 or 68+8. It is impossible to harvest the high-yield wide-narrow row spacing 60+30 in Xinjiang, my country, and the adaptability of cotton pickers is poor
