Problems solved by technology

[0004] At present, there is a lack of equipment suitable for pasture reseeding in my country, and there are very few devices that can meet the simultaneous mixed sowing and simultaneous fertilization of multiple varieties of pasture seeds. It is particularly important to develop supplementary sowing equipment suitable for degraded grassland management.

Embodiment 1

[0029] Such as Figure 1-Figure 3 As shown, the present embodiment provides a multi-stage variable speed sprocket gearbox for mixed sowing of multi-variety herbage seeds and synchronous fertilization, including a sprocket gearbox input shaft and a sprocket gearbox output shaft. There are 6 sprockets with different numbers of teeth coaxially arranged on the shaft of the input end of the sprocket gearbox, which are respectively the first sprocket 23, the second sprocket 24, the third sprocket 25, the fourth sprocket 26, and the fifth sprocket. Wheel 27, the sixth sprocket 28, the seventh sprocket 29 and the eighth sprocket 30 with two different numbers of teeth are coaxially arranged on the sprocket gearbox output shaft, and the seventh sprocket 29, the eighth sprocket 30 is slidingly connected with the output shaft of the sprocket gearbox, and is tightened and fixed by a fastening screw 33 respectively. The sprocket wheel on the input shaft of the sprocket gearbox is connected ...

Embodiment 2

[0033] Such as Figure 4-8 As shown, the present embodiment provides a kind of multi-variety forage grass seed mixed sowing, synchronous fertilization multi-stage variable speed transmission device, including the sprocket gearbox provided in embodiment 1, also including road wheel 2, friction wheel 3, ninth sprocket 4 And chain I5, tenth sprocket 6, eleventh sprocket 8, twelfth sprocket 9, chain II10, thirteenth sprocket 11, chain III12, fourteenth sprocket 13, output sprocket 15, chain Ⅳ16 15th sprocket 17, chain Ⅴ20, 16th sprocket 21, sprocket A7, sprocket B14, sprocket C18, sprocket D22,

[0034]Specifically, when it is necessary to sow, the upper end of the hydraulic cylinder 1 returns oil, and the road wheel 2 will rotate clockwise along the rotation axis at point O. When it contacts the friction wheel 3, the road wheel 2 will stop rotating around point O, and the friction wheel will be driven 3 Turn counterclockwise, the ninth sprocket 4 fixedly connected to the frictio...

Abstract

The invention discloses a multistage variable-speed sprocket gearbox for performing mixed sowing on many varieties of grass seeds and performing synchronous fertilization. In addition, the invention further provides a multistage variable-speed transmission device for performing mixed sowing on many varieties of grass seeds and performing synchronous fertilization. The multistage variable-speed sprocket gearbox provided by the invention can realize 12 times speed change and can adjust the sowing quantity flexibly and efficiently when being applied to a whole machine; the sprocket gearbox is applied to the transmission device and the transmission device is applied to the whole machine, so that the multistage variable-speed function of simultaneously sowing and synchronously fertilizing manyvarieties of degraded grassland of the whole machine can be realized, and equipment support is provided for adjusting the sowing quantity in a large proportion, supplementarily sowing different shapesof grass seeds and performing synchronous fertilization.

Description

technical field [0001] The invention relates to the technical field of degraded grassland management equipment, in particular to a multi-stage variable-speed sprocket gearbox and a transmission device for mixed sowing of multi-variety herbage seeds and synchronous fertilization. Background technique [0002] In recent decades, with the intensification of human activities, unreasonable grazing systems, blind reclamation, predatory utilization and other human factors, as well as the impact of changes in unfavorable natural factors, 90% of my country's grasslands have been affected to varying degrees. degradation phenomenon. Grassland degradation has led to the reduction of grassland area in my country, the decline of grassland productivity, the reduction of a large amount of high-quality forage grass, the loss of biodiversity, the intensification of soil erosion, the dysfunction, imbalance and decline of ecosystem functions, and the composition and structure of grassland plant ...
