[0002] Grape is a kind of warm crop, and its cold resistance is poor. In the area where the air temperature is low in winter, the measure of burying soil is usually adopted to prevent cold in winter. The pruned grapevine is pressed on the ground, and the soil is covered on the grapevine, so that the part of the vine exposed to the cold and dry air can be reduced, and the grapevine is protected from freezing and drying. Moreover, the grape root system can be effectively protected by soil covering to avoid damage caused by low temperature in winter, so that the grape yield can be increased in the coming year.

[0003] The common burying and covering method in China is that a tractor drives a certain angle of scraping shovel to advance, and the soil is buried in the grape branch by the physical structure of the scraping shovel.

[0045] In one broad embodiment of the utility model, the cutting rotary scraping combined type earth burying device has the structure as Figure 1As shown, mainly includes: three-axis gearbox 1, belt 2, transmission shaft 3, main drive pulley 4, two-axis gearbox 5, tension pulley 6, rotary blade shaft fixing frame 7, rotary blade shaft adjusting plate 8, driven pulley 9, driven pulley rotary shaft 10, rotary blade shaft connecting drum fixing plate 11, soil scraping shovel 12, rotary blade shaft connecting drum 13, rotary blade shaft upper connecting plate 14, rotary blade shaft lower connecting plate 15, rotary blade shaft 16, rotary blade seat 17 and rotary blade 18.

[0046] The rotary blade 18 rotates with the rotation of the rotary blade shaft 16, contacts the soil during operation, and rotates the soil, and then the soil scraping shovel 12 scrapes the rotated soil to the grapevine, thereby burying the soil.

[0047] The power for rotating the rotary blade shaft 16 comes from the tractor rear output shaft. Specifically, the power of the tractor rear output shaft is transmitted to the rotary blade shaft 16 through the gearbox, the main drive pulley 4, the belt 2, the driven pulley 9, the driven pulley rotary shaft 10, the rotary blade shaft upper connecting plate 14, and the rotary blade shaft lower connecting plate 15.

[0048] The gearbox has two types of three-axis gearbox 1 and two-axis gearbox 5. Specifically, the two types of gearboxes are identical in other parameters except for the number of shafts.

[0049] The three-axis gearbox 1 is directly connected to the tractor rear output shaft at the front, connected to the main drive pulley 4 at the top, and connected to the two-axis gearbox 5 at the back through the transmission connecting shaft 3.

[0050] The two-axis gearbox 5 is connected to the three-axis gearbox 1 at the front through the transmission connecting shaft 3, and connected to the main drive pulley 4 at the top.

[0051] Specifically, the three-axis gearbox 1 and the two-axis gearbox 5 have the same type, size, installation height, and other parameters of the main drive pulley 4 at the top. The diameter of the main drive pulley 4 is d1, and the range of d1 is 100-400 mm. In this embodiment, d1=200 mm is preferred.

[0052] The number of belts 2 on each main drive pulley 4 is the same, but the lengths are different, and the belts near the soil scraping shovel tip 1201 are shorter.

[0053] Specifically, the number of belts 2 on each main drive pulley 4 is m. To ensure the effectiveness of power transmission, the value of m ranges from 2 to 10. In this embodiment, m=3 is preferred.

[0057] The rotary blade shaft connecting drum 13 has a bearing inside to support the rotation of the driven pulley rotating shaft 10.

[0058] The driven pulley 9 is fixed to the driven pulley rotating shaft 10.

[0059] Specifically, the two driven pulleys 9 are identical in type, size, installation height, and other parameters. The diameters of the driven pulleys 9 are d2, and the range of d2 is 40-340 mm. It should be noted that the diameter d2 of the driven pulley 9 is smaller than the diameter d1 of the main drive pulley 4, i.e., d2 < d1. In this embodiment, d2 = 140 mm.

[0065] The rotary tiller seat 17 is connected with the rotary tiller 18 by bolts, so as to facilitate the disassembly and replacement of the rotary tiller 18.

[0066] Specifically, the number of rotary tillers 18 is k, and the number is the same as the number of rotary tiller seats 17, that is, k = n, the value range of k is 2-16, preferably, in this embodiment, k = 8. It should be noted that the installation direction of the rotary tiller 18 is the same, as shown in Figure 3 , and the bent convex part is downward, as shown in Figure 4 ; when designing or calculating the number of rotary tiller seats 17 or rotary tillers 18, it is necessary to ensure that each rotary tiller 18 does not interfere with each other.

It should be noted that since the soil scraping shovel tip 1201 first contacts the soil, the countersunk bolt 1204 is used to reduce friction, and the side contacting the soil is beveled to better scrape the soil. Since the soil scraping shovel tip 1201 is easily damaged, the bolt connection is used to facilitate replacement.

[0069] The soil scraping shovel body 1202 has a certain arc, and the lower edge, except for the part where the soil scraping shovel tip 1201 is installed, is a horizontal line, and the rest is an inclined line, as shown in Figure 5 and Figure 6 , so that the soil can be better scraped to the grapevine.

[0070] The soil scraping shovel welding lug 1203 is fixed with the soil scraping shovel body 1202, and is fixed with the rack by a U-shaped bolt, as shown in Figure 5 , the position of the soil scraping shovel welding lug 1203 can be changed by adjusting the position of the U-shaped bolt connection, and the position of the soil scraping shovel body 1202 can be changed. It should be noted that when adjusting the position of the soil scraping shovel body 1202, it is necessary to ensure that it covers the working range of the rotary tiller 18 on the two rotary tiller shafts 16 as much as possible.

[0071] The blade body reinforcing rib 1205 is fixed with the blade welding lug 1203 and the convex surface of the blade body 1202, as shown in the figure. Figure 6 Specifically, the number of the blade body reinforcing rib 1205 is a, and the value range of a is 1-10, and preferably, a=3 in the embodiment.
