According to the machine weight, harrow depth, and harrow blade diameter, the harrow group of a land preparation machine can be divided into three types: heavy, medium, and light. The heavy type is suitable for land reclamation, low-temperature land, and heavy clay soil; the medium type is suitable for breaking up the soil after plowing clay loam; and the light type is suitable for breaking up the soil after loam. According to the configuration of the harrow group, it can be divided into opposed and offset types. The opposed harrow groups are symmetrically arranged on both sides of the center line of the tractor, while the offset type has the harrow group offset to the rear right side of the tractor.

[0028] See also Figure 1-10 , the present invention provides a technical solution:

[0029] A land leveling machine rake group for leveling the ground comprises a machine rake group body 1, a top frame 2 is fixedly installed at the bottom end of the frame of the machine rake group body 1, a first outer cover 21 and a second outer cover 22 are fixedly installed on the inner wall of the top end of the top frame 2, an outer grille 3 is rotatably connected between the inner walls of the first outer cover 21 and the second outer cover 22, an inner grille 31 is slidably connected to the inner wall of the outer grille 3, two ends of the outer grille 3 are rotatably connected to the inner wall of the bottom end of the top frame 2, a collecting assembly 4 is fixedly installed on the outer side of the outer grille 3, and the inner wall of the outer grille 3 is rotatably connected to the inner wall of the bottom end of the top frame 2 There is a driving shaft 5, both ends of which are rotatably connected to the inner walls of the first outer cover 21 and the second outer cover 22 respectively, and both ends of the driving shaft 5 are also rotatably connected to the inner wall of the bottom end of the top frame 2, a plurality of side plates 51 are fixedly installed on the outer side of the driving shaft 5, a plurality of first electric hydraulic rods 52 are fixedly installed on the outer sides of the plurality of side plates 51, crushing plates 53 are fixedly installed on the telescopic ends of the plurality of first electric hydraulic rods 52, a plurality of scraping rods 54 are also fixedly installed on the outer side of the driving shaft 5, and a driving assembly 6 is provided on the inner side wall of the top frame 2.

[0030] During specific use, when using the land preparation machine harrow group, the machine harrow group body 1 performs land preparation operations on the land. During the land preparation process, the driving shaft 5 can be driven by the driving component 6, so that the driving shaft 5 can drive the scraper rod 54 and the side plate 51 to rotate, which can increase the scraping of the plastic film into the inner grille 31, and collect and screen large particles of material through the outer grille 3 and the inner grille 31, and the size of the grille outlet between the inner grille 31 and the outer grille 3 can be adjusted according to the size of the garbage remaining in the field. After screening the large particles, the reciprocating action of the crushing plate 53 can be driven by the first electric hydraulic rod 52, so that some of the large particles can be squeezed and crushed by the crushing plate 53, and the soil blocks become The smaller particles can leak out from the outer grille 3 and the inner grille 31, while the remaining hazardous waste cannot be crushed and can remain stored inside the outer grille 3 and the inner grille 31, thereby increasing the function of the harrow group of the land leveling machine to collect garbage in the field. When there is a lot of garbage stored in the inner grille 31, the driving control of the outer grille 3 can be carried out through the driving component 6, so that the outer grille 3 rotates on the inner walls of the first outer cover 21 and the second outer cover 22, so that the outer grille 3 can simultaneously drive the collecting component 4 to follow the rotation. When the collecting component 4 rotates downward to the bottom and is horizontal, it can be opened to collect garbage such as broken porcelain pieces inside the outer grille 3, and thinner garbage such as plastic film wrapped on the driving shaft 5 and the scraper 54 can be regularly cleaned manually.

[0031] In this embodiment: the collecting assembly 4 includes a collecting box 41 fixedly installed on the outside of the outer grille 3, and a first limiting ring 42 and a second limiting ring 43 are fixedly installed on both ends of the outside of the collecting box 41, and the outsides of the first limiting ring 42 and the second limiting ring 43 are rotatably connected to the inner walls of the first outer cover 21 and the second outer cover 22 respectively, and the inner wall of the collecting box 41 is slidably connected to a collecting drawer 44, and a fixing rod 45 is threadedly connected to the inner wall of one end of the collecting box 41, and the outer side of the top end of the fixing rod 45 is threadedly connected to the inner wall of one end of the collecting drawer 44.

[0032] During specific use, when the collecting box 41 rotates with the outer grille 3, the first limiting ring 42 can be rotated inside the first outer cover 21, and the second limiting ring 43 can be rotated inside the second outer cover 22. After the collecting box 41 moves to the initial position, the collected garbage can be stored in the collecting bin 44 by gravity, and the collecting bin 44 can be separated from the top of the fixing rod 45 by rotating the fixing rod 45, so that the collecting bin 44 can be pulled out from the inside of the collecting box 41, which is convenient for the disposal of the garbage inside the collecting bin 44.

[0033] In this embodiment: the collecting assembly 4 also includes an opening and closing shaft 46 rotatably connected to the inner wall of the collecting box 41, and the other end of the opening and closing shaft 46 is respectively fixedly installed with a driving gear 47 and a limit block 48, the outer side of the limit block 48 is slidably connected to the inner wall of the second outer cover 22, and the inner wall of the second outer cover 22 is respectively fixedly installed with an inner gear ring 49 and an outer gear ring 410.

[0034] When in use, when the collection box 41 has not rotated to the lower horizontal position, the limit block 48 slides inside the second outer cover 22 and does not rotate. When the collection box 41 rotates to the lower horizontal position, the limit block 48 is not limited by the second outer cover 22. At this time, the driving gear 47 is engaged with the inner gear ring 49, so that the opening and closing shaft 46 can be rotated inside the collection box 41 to open the feeding port of the collection box 41, and the limit block 48 is limited and slides with the second outer cover 22 again, so that the collection box 41 can be kept open continuously. At this time, through the rotation of the outer grille 3, the garbage inside the outer grille 3 can be dropped into the collection box 41 for collection. When the collection box 41 is rotated upward to a vertical state, the limit block 48 can be again not limited by the second outer cover 22. At this time, the driving gear 47 is acted on by the outer gear ring 410, so that the opening and closing shaft 46 rotates in the opposite direction to close the collection box 41, thereby preventing the debris inside the collection box 41 from spilling out.

[0035] In this embodiment: the driving assembly 6 includes two driving rods 61 rotatably connected to the inner wall of the top frame 2, the two driving rods 61 and one end of the driving shaft 5 are fixedly installed with a first pulley 62, the other end of the outer grille 3 is fixedly installed with a second pulley 63, and the outer sides of the first pulley 62 and the second pulley 63 are respectively sleeved with a first transmission belt 64 and a second transmission belt 65.

[0038] During specific use, the aperture sizes of the outer grille 3 and the inner grille 31 for screening can be adjusted by driving the inner grille 31 to slide horizontally through the second electric hydraulic rod 32, so that the apertures of the inner grille 31 and the outer grille 3 can be overlapped, thereby achieving the effect of adjusting the aperture size.

[0039] In this embodiment, a telescopic cover 55 is sleeved on the outer side of the first electric hydraulic rod 52 , and two ends of the telescopic cover 55 are fixedly connected to the outer sides of the side plate 51 and the crushing plate 53 respectively.
