Embodiment 1

[0033] Such as figure 1 As shown, the ditching system of this embodiment includes a power output port 1, a first steering knuckle 21, a power output shaft 3, a second steering knuckle 22, a reversing gearbox 4, a third steering knuckle 23, and a power transmission shaft 5 , Rolling bearing 6, driving sprocket 7, double chain 8, driven sprocket 9, cutterhead installation shaft 10, flange cutterhead 11, ditching knife 12, bolt 13. The power output port 1 is connected to the tractor diesel engine, and the power and motion are transmitted to the power output shaft 3 through the first steering knuckle 21, and the power output shaft 3 is connected to the reversing gearbox 4 through the second steering knuckle 22, and the power and motion Transfer to the reverse gearbox 4; the reverse gearbox 4 includes an input shaft 41, a driving bevel gear 42, a driven bevel gear 43, and an output shaft 44, and the input shaft 41 is connected with the power output shaft 3 through the second steeri...

Embodiment 2

[0048] This embodiment is to carry out the durability test on the ditching system, and is to check the continuous working ability of the ditching system. The test process is as follows: the ditching system of this embodiment is installed on a certain type of tractor (the maximum output speed of the tractor diesel engine is 2200 rpm ), driven by a tractor, the ditching system ditched for 200 kilometers, randomly selected 100 points in this interval to measure the ditching depth, calculated the average ditching depth and the ditching depth was between 30 and 70 mm to reflect the ditching effect of the ditching system; in the working area of ​​the ditching system, arbitrarily select a length of 100 meters, and count the number of large pebbles with an average diameter of more than 30 cm; select any one of the ditches , the length is selected as 1 meter, and an area of ​​5 cm on each side of the ditch and a depth of 10 cm is selected, and the number of small and medium-sized pebble...

Embodiment 3

[0063] This embodiment is basically the same as Embodiment 2, except that the transmission ratio of the ditching system is set to 3:1, and the distribution ratio of the transmission ratio is as follows: the reversing gearbox 4 is a speed reducer, and the transmission ratio is set to 2:1, The number of teeth of the driving bevel gear 42 and the driven bevel gear 43 are 30 and 60 respectively; the chain transmission mechanism composed of the driving sprocket 7, the double chain 8 and the driven sprocket 9 is a reducer, and the transmission ratio is set to 1.5:1. The number of teeth of sprocket 7 and driven sprocket 9 are 40 and 60 respectively. Normally, the maximum rotational speed of the tractor diesel engine does not exceed 2400 rpm, and this embodiment ensures that the maximum rotational speed of the ditching knife 12 does not exceed 800 rpm. The test results are shown in Table 9 to Table 12:

Abstract

The invention discloses a ditching system suitable for the surface layer of natural grassland of a high-altitude cold region. The ditching system comprises a power steering device, a power transferring device and a ditching device. The power steering device is connected with external power, and is used for steering the external power and transferring the power to the power transferring device. Thetwo ends of the power transferring device are connected with the power steering device and the ditching device respectively, and used for transferring the power transferred by the power steering device to the ditching device. The ditching device comprises a plurality of ditching cutters, and used for receiving the power transferred by the power transferring device and driving the ditching cuttersto carrying out ditching work on the surface layer. According to the ditching system, the problem about ditching at the state that gravel in a soil layer is large in scale and is densely distributedis solved, the ditching effect is good, and the ditching system is of great significance on ecological protection and construction of the natural grassland of the high-altitude cold region.

Description

technical field [0001] The invention belongs to the technical field of special equipment, and in particular relates to a ditching system suitable for the surface layer of natural grass in high-altitude cold regions. Background technique [0002] In high-altitude cold regions, the ecological recovery ability of natural grasslands is extremely weak, coupled with overgrazing due to human factors, which exceeds the livestock carrying capacity of natural grasslands, resulting in varying degrees of vegetation degradation in natural grasslands. In order to realize the vegetation restoration of natural grasslands in high-altitude cold areas, no-tillage supplementary seeding technology is applied in the ecological protection and construction of large-scale natural grasslands, and strives to achieve pasture sowing under the premise of a small amount of soil, and finally achieve vegetation restoration and The goal of ecological protection. [0003] So far, people have carried out the ...
