Embodiment 1

[0030] like figure 1 Shown, be the structural representation of the present invention, industrial hemp combine harvester, comprise cab 15, engine 16, combine harvester body 17, combine harvester steering wheel 18, combine harvester driving wheel 19, combine harvester former Crossing the bridge 20 also includes a harvesting device, and the harvesting device includes a disc cutter system, a two-stage bridge crossing system 13, a lifting spinning frame system, a reel 12, a harvesting platform 10, and a cutting and drying platform 9, and the harvesting device is installed on the combine harvester The front end of the combine harvester is connected to the front end of the combine harvester body through the original bridge of the combine harvester. The first half of the harvesting device is the reel, the harvesting platform, and the windrowing platform. The reel is located above the harvesting platform, and the harvesting platform is located above the windrowing platform. The harves...

Embodiment 2

[0037] The same as the technical solution of embodiment 1, the difference is that the distance h between the cutting table cutter and the hemp ear tip and the advancing speed V of the harvester are as follows:

[0038] 3.3V+6.7≥h≥2.2V+7.8, where 10m / s≥V≥1m / s, h is in cm. like Figure 9 shown.

[0039] Within this relationship, it can be guaranteed that the machine can harvest the hemp seeds most efficiently, and the hemp seeds will not be lost as much as possible.

[0040] A further preferred h=2.5V+7.5, in this state, the machine can achieve the best operating and harvesting state, that is, the most energy saving and the highest harvesting efficiency.

[0041] The most preferred solution is h=2.5V+7.5, further V=1.25.

Embodiment 3

[0043] The same as the technical solution of embodiment 1, the difference is that the reel rotational angular velocity w 1 The relationship with the operating speed V of the harvester is:

[0044] 1.67V 2 +18.33≥w 1 ≥V 2 +14, 4m / s≥V≥1m / s, w 1 The unit is rev / min. like Figure 10 shown.

[0045] Within this range, it can effectively ensure that the grains will not accumulate due to too slow transmission speed, and will not cause idling and waste energy due to too fast transmission speed.

[0046] The most optimal solution is w 1 =1.143V 2 +14.857, further V=2.5.

Abstract

The invention relates to the technical field of the design of harvesting machinery in agriculture and forestry, specifically to a disc cutter system for an industrial hemp combine harvester. The disccutter system for the industrial hemp combine harvester comprises total power input belt wheels 21, harvesting platform driving belt wheels 14, disc cutter intermediate transmission belt wheels 7, disc cutter transmission belts 6 and disc cutter blades 8, wherein the total power input belt wheels are arranged at two sides of the lower end of an original combine harvester gap bridge; the harvestingplatform driving belt wheels are arranged at the lower end of a harvesting platform gap bridge; the disc cutter intermediate transmission belt wheels are arranged on a swathing platform; each total power input belt wheel is connected with one harvesting platform driving belt wheel through a transmission belt; and each harvesting platform driving belt wheel is a two-stage belt wheel and is connected with one disc cutter intermediate transmission belt wheel through the disc cutter transmission belt. The industrial hemp combine harvester provided by the invention firstly combines the disc cuttersystem with the swathing platform, overcomes the problem of influence on operation due to generation of heaping and hanging of male hemp during harvesting of female hemp, and further improves operation efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry harvesting machinery design, in particular to an industrial hemp combine harvester for hemp harvesting. Background technique [0002] Hemp is a plant of Moraceae and Cannabis genus. The stem bark fiber is long and tough. It is used for weaving linen or spinning thread, making ropes, etc. The seeds are oil-pressed, with an oil content of 30%. The fruit is called hemp seed in traditional Chinese medicine, which has medical effects. According to the "Method for Remediating Petroleum Hydrocarbon Contaminated Soil Using Hemp" recorded in Patent No. 201410472327.9, hemp also has the function of continuously reducing petroleum hydrocarbon pollutants in polluted soil until the pollutant content reaches the national environmental standard. Hemp is an annual erect herbaceous plant with mature cultivation techniques, a set of systematic sowing and fertilization measures and a scientific fi...
