Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, and particularly relates to a seed cutting platform of a sugarcane intelligent seed cutter. Background Art

[0002] In the process of sugarcane planting, the manual labor intensity is high and the planting cost is high. At present, manual and semi-mechanical seed cutting methods are mainly used in China to prepare sugarcane seeds, which lag behind mechanized seed preparation in terms of seed cutting efficiency, labor intensity, and seed quality. In order to improve the sugarcane seed cutting efficiency, sugarcane seed cutters have emerged. However, the overall working efficiency of the existing sugarcane seed cutters is still low, and the automation level and seed cutting quality are not high. Most of the existing sugarcane seed cutters can only cut each sugarcane at equal intervals in sequence, with low working efficiency. Since the lengths of the sugarcane nodes are different, cutting at equal intervals will cause some cuttings to fall on the nodes or near the buds, and the cut sugarcane seeds cannot germinate, thus unable to ensure the germination rate and the good seed rate of the sugarcane seeds. In order to cut sugarcane seeds with different node lengths, the existing sugarcane seed cutters have been improved. For example, the Chinese patent application publication number is CN109168499A, and the name is a sugarcane pre-seed cutting workstation. This workstation can adjust the cutting positions of each cutting mechanism for sugarcane according to the positions of the sugarcane nodes obtained by the node recognition device, so that the cuttings avoid the nodes and buds. The Chinese patent application publication number is CN 109227720 A, and the name is an automatic cutting platform of a horizontal sugarcane seed cutter. This cutting platform is provided with a number of seed cutting workbenches. Each seed cutting workbench can move left and right according to the position of the sugarcane node to avoid the node position and cut the sugarcane, so as to prevent the cuttings from falling on the nodes or near the buds. However, when adjusting the cutting interval of the seed cutting workbench, the working process of the intelligent seed cutting equipment is complex and the efficiency is low, which cannot meet the short-time and high-efficiency seed cutting requirements of sugarcane planting.

The tool adjusting mechanism 5 is connected to the seed cutting mechanism 3 and the feeding mechanism 4 to adjust the positions of the seed cutting mechanism 3 and the feeding mechanism 4 to avoid cutting at the sugarcane joint position.

[0025] The specific structure is as follows. The seed cutting platform includes a frame 2. The seed cutting mechanism 3 is arranged on the frame 1. The seed cutting mechanism 3 includes a plurality of saw blades 31 and a driving mechanism 6. The plurality of saw blades 31 are arranged at intervals on the same straight line. The saw blades 31 are connected to the driving mechanism 6. The saw blades 31 are driven to rotate by the driving mechanism 6. A feeding mechanism 4 is arranged below the saw blades 31. The feeding mechanism 4 includes a first spline shaft 41 and a plurality of dial wheels 42. The first spline shaft 41 is a ball spline shaft, one end of which is connected to a stepping motor 43 and is arranged on the frame 2. The first spline shaft 41 is driven to rotate by the stepping motor 43. The plurality of dial wheels 42 are arranged at intervals on the first spline shaft 41 and can move left and right. There is an arc-shaped gap between every two teeth of the dial wheels 42. The gear gaps of the plurality of dial wheels 42 are arranged on the same straight line to form a sugarcane receiving channel. It is convenient to accommodate the sugarcane and provide a thrust for the sugarcane during sugarcane cutting so as to complete rapid cutting.

The first fork 46 pushes the spline shaft sleeve 45, the one-way thrust bearing 44, and the dial 42 to move left and right on the first spline shaft 41. The efficient cutting mechanism moving action can be completed while the dial 41 keeps rotating.

The left and right movement of the moving beam 53 drives the saw blade 31 and the dial 42 to move synchronously in the left and right directions.

[0031] When using the seed cutting platform of the present invention, the sugarcane is conveyed by the sugarcane seed conveying chain 1. When passing through the sugarcane seed recognition device, the camera of the sugarcane seed recognition device dynamically samples the sugarcane image to obtain the sugarcane node information of the sugarcane seed, and sends this node information to the computer control system. If the tool adjustment action of the seed cutting mechanism is not completed when the sugarcane is conveyed to the end of the sugarcane seed conveying chain 1, the sugarcane seed conveying chain 1 stops running. The saw blade 31 remains in a rotating state. According to the cutting position calculated by the computer, the tool adjustment mechanism 5 drives the saw blade of the seed cutting mechanism 3 to move to the cutting position. After the tool adjustment is completed, the sugarcane falls from the end of the sugarcane seed conveying chain 1 and falls into the tooth gap of the dial 42. The dial 42 starts to rotate, presses the sugarcane against the saw blade 31 until the cutting is completed, and the dial 42 continues to rotate to push the sugarcane seeds to fall automatically, and a round of seed cutting work is completed.
