Problems solved by technology

[0004] (1) When harvesting corn stalks, because the saw blade is almost close to the ground and rotates at high speed, the saw teeth are easily damaged when they encounter hard stones, bricks, etc.
[0005] (2) The thickness of corn stalks is different. Since the cutting time of different corn stalks is different, if the speed of the reel remains the same, either the stalks will be cut If the straw is not dialed in in time, the feeding of the straw is messy, forming a blockage; or the straw is forced to be dialed in when the straw is not cut, causing excessive force on the reel, slipping of the belt, loss of a lot of power, and affecting harvesting efficiency

Embodiment 1

[0030]Example 1 The first and second reels 13 and 14 are configured at different speeds when harvesting corn stalks with a plant diameter of 2 cm.

[0031] The design and calculation of the first and second reels 13 and 14 of the corn stalks with a diameter of 2 cm for harvesting:

[0032] According to the actual test, the harvesting speed of the harvester is:

[0033] v max =0.4963m / s

[0034] v min =0.4415m / s

[0035] Corn stalk diameter d 2 2cm

[0036] ie: d 2 =0.02m

[0037] Then: the time it takes for the harvester to cut 2cm corn stalks

[0038] t 2min =0.02 / 0.4963=0.040 (s) (the minimum time required for cutting)

[0039] t 2max =0.02 / 0.4415=0.045 (s) (the longest time required for cutting)

[0040] Calculation of the speed of the reel:

[0041] The hook-shaped reeling teeth 25 at the bottom of the first and second reeling cylinders 13 and 14 have 16 teeth. The saw blades 10, 11 completely cut the corn stalk, and the hook reel tooth 25 r...

Embodiment 2

[0051] Example 2 The rotational speed configuration of the first and second reels 13 and 14 when the diameter of corn stalks harvested by the header is 4 cm.

[0052] Design and calculation of first and second reels 13 and 14 rotating speeds when harvesting corn stalks with a plant diameter of 4 cm:

[0053] According to the actual test, the harvesting speed of the harvester is:

[0054] v max =0.4963m / s

[0055] v min =0.4415m / s

[0056] Corn stalk diameter d 4 4cm

[0057] ie: d 4 =0.04m

[0058] Then: the time it takes for the harvester to cut the corn stalk

[0059] t 4 min =0.04 / 0.4963=0.080 (s) (the minimum time required for cutting)

[0060] t 4 max =0.04 / 0.4415=0.090 (s) (the longest time required for cutting)

[0061] First and second reel 13, 14 rotational speed calculation:

[0062] The hook-shaped reeling teeth 25 at the bottom of the first and second reeling cylinders 13 and 14 have 16 teeth. The saw blades 10 and 11 completely cut ...

Embodiment 3

[0072] Example 3 The first and second reels 13 and 14 rotate speed and the configuration of the hook-shaped reels 25 when the diameter of the corn stalks harvested by the header is 4 cm to 6 cm.

[0073] Design and calculation of the rotation speed of the first and second reels 13 and 14 for harvesting corn stalks with a plant diameter of 4cm~6cm:

[0074] According to the actual test, the harvesting speed of the harvester is:

[0075] v max =0.4963m / s

[0076] v min =0.4415m / s

[0077] Corn stalk diameter d 46 4cm~6cm

[0078] ie: d 46 =0.04m~0.06m

[0079] harvester with v min = Traveling at a speed of 0.4415m / s

[0080] Then: the time it takes for the harvester to cut the corn stalk

[0081] t 46 min =0.04 / 0.4415=0.090 (s) (the minimum time required for cutting)

[0082] t 46 max =0.06 / 0.4415=0.136 (s) (the longest time required for cutting)

[0083] Adjustment of the number of teeth of the first and second reel 13, 14 bottom hook-shaped r...

Abstract

The invention relates to a non-lining corn stalk harvesting machine header adapting to different plant diameters. A grain gathering rod is fixedly connected with the front end of a steering shaft bracket, and grain dividing teeth are installed on the end head of a lower cross beam of the front end of a header rack in a uniformly-spaced mode; a first disk saw blade and a second disk saw blade are installed at the lower ends of inner shafts of a concentric sleeve shaft, and a first grain poking roller and a second grain poking roller are installed on outer shafts of the concentric sleeve shaft; and the inner shafts and the outer shafts of the concentric sleeve shaft are connected with each other through bearings, and the inner shafts of the concentric sleeve shaft are installed on the lower cross beam of the front end of the header rack side by side. The non-lining corn stalk harvesting machine header can harvest corn stalks with different plant diameters, different planting densities and different heights in different seasons; under the clamping delivery of the grain gathering rod at the front end of the header, the grain dividing teeth and grain poking teeth on a pair of grain poking rollers, crop stalks are cut off by the saw blades and then are fed in from the root part, the stalks are uniformly arrayed and are tidily fed in, the feeding is smooth, and the blocking is not easily generated; and the harvesting loss is small, the power consumption is low, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a non-divided corn stalk harvester cutting platform adapted to different plant diameters, specifically a kind of saw blade is protected, and when harvesting corn stalks, the rotating speed of the reel drum and the number of teeth of the bottom reel are based on different Corn stalk harvester header with adjustable corn stalk thickness without branching. Background technique [0002] The self-propelled green forage harvester has the characteristics of high harvesting efficiency and good operating performance, and is more popular in large and medium-sized farms. However, in terms of the adaptability of the green forage harvester, due to the vast territory of our country, the seasons of different regions are quite different, and the crop varieties are not the same, and there are different planting patterns in different regions or even in the same region. The height of the growth...
