[0053] Among them, in order to achieve the purpose of reducing wear, the present device is implemented by the following technical solutions: two mounting blocks 62 are fixedly connected to the top of the connecting plate 3, a connecting frame 63 is fixedly connected to the connecting plate 3 and the top of the casing 1, two reinforcing rods 1 64 are fixedly connected between the connecting frame 63 and the connecting plate 3, and reinforcing rods 2 65 are fixedly connected between the connecting frame 63 and the two support plates 2, the rotating shaft 1 7 is connected to the casing 5 through bearings, the reciprocating screw 12 is connected to the support block 11 and the casing 5 through bearings, the rotating block 16 is connected to the casing 1 through bearings, and the rotating shaft 2 36 is connected to the outer casing 19 through bearings. The bearing connection can reduce wear.
[0054] The use process of the present invention is as follows: the existing support frame is connected to the connecting frame 63 on the present device by bolts, and then the present rake body can be installed on the tractor through the support frame, and then the existing driving device is installed on the mounting block 62 by bolts, and at the same time, the second rotating shaft 36 is connected to the driving device by bolts under the action of the flange 37, so that the tractor can transmit power to the driving device when working, and then the driving device can make the second rotating shaft 36 rotate, and the rotation of the second rotating shaft 36 drives the second bevel gear 35 to rotate, and the rotation of the second bevel gear 35 drives the first bevel gear 34 to rotate, and the rotation of the first bevel gear 34 drives the middle rotating block 16 to rotate, and then under the action of multiple third gears 33, multiple rotating blocks 16 can be rotated at the same time, and the rotation of multiple rotating blocks 16 drives multiple square blocks 22 to rotate, and then drives multiple cutter discs 17 and rake teeth 18 to rotate, so that the soil can be crushed;
[0055] When the rake teeth 18 are damaged during use and need to be replaced and maintained, the motor 6 is controlled to rotate forward, and the motor 6 rotates forward to drive the shaft 1 7 to rotate, and the rotation of the shaft 1 7 drives the first gear 8 to rotate, and the rotation of the first gear 8 drives the second gear 13 and the fourth gear 47 to rotate. Since the fourth gear 47 is connected to the reciprocating screw 2 46 through a one-way bearing, the reciprocating screw 2 46 does not rotate when the motor 6 rotates forward, and the rotation of the second gear 13 drives the reciprocating screw 12 to rotate. The rotation of the reciprocating screw 12 can make the sliding seat 14, the connecting rod and the piston 10 move to the left, and then under the action of the pipeline 2 21, the pipeline 1 20 and the multiple pipelines 30, the air in the multiple boxes 3 50 can be sucked away, and then The two pistons on each box body 3 50 will move toward the middle, thereby moving the block 26 out of the slot 27, and the spring 1 29 will be compressed. Then, the rake teeth 18 and the cutter disc 17 can be manually pulled downward to remove the rake teeth 18, thereby achieving a quick disassembly effect. When installing, align the groove 23 with the square block 22 and insert it back. Then, the magnet 1 31 and the magnet 2 32 are attracted together, and then the motor 6 is controlled to continue to rotate forward. Then, the reciprocating screw 12 rotates to make the sliding seat 14, the connecting rod and the piston 10 move to the right, so that the air can be filled back. At the same time, under the action of the spring 1 29 rebounding, the block 26 can be stuck in the slot 27 again, thereby completing the installation of the cutter disc 17 and the rake teeth 18;
[0056] When the soil is crushed, the housing 5 controls the motor 6 to reverse. Since the first gear 8 and the reciprocating screw 12 are also connected through a one-way bearing, the reciprocating screw 12 does not rotate when the motor 6 is reversed, but the reciprocating screw 2 46 rotates. The rotation of the reciprocating screw 2 46 drives the sliding seat 2 48 to continuously move left and right, thereby causing the connecting strip 45, the U-shaped frame 2 43 and the plurality of gear frames 44 to continuously move left and right, so that the soil can be leveled when the soil is crushed, thereby avoiding the phenomenon of uneven soil.
[0057] When the soil is being leveled, the pressing roller 41 will press over the soil, so that the surface of the soil can be compacted when the soil is crushed, which can increase the bulk density of the soil, reduce the porosity, form a better aggregate structure, and be beneficial to the retention of water and nutrients, thereby promoting the root growth of crops and the germination of seeds;
[0058] When the sliding seat 2 48 moves left and right, it can also push the two moving rods 1 52 to move in turn, thereby moving the two pistons 3 51. Then, under the action of the pipe 6 61, the pipe 4 59 and the multiple pipes 5 60, the air in the box 3 50 can flow back and forth with the air in the multiple boxes 4 54, so that the multiple pistons 4 55, the multiple moving rods 2 56, the fixed bar 57 and the multiple scrapers 58 can be pushed to move back and forth, so that the scraper block 58 can intermittently contact the pressing roller 41. Since the pressing roller 41 will rotate when the device is in use, the scraper block 58 can scrape off the dirt adhered to the pressing roller 41 when it contacts the pressing roller 41, and when scraping, the scraper block 58 is in intermittent contact with the pressing roller 41, not in continuous contact, which can reduce the friction between the scraper block 58 and the pressing roller 41, thereby increasing the service life of the scraper block 58 and the pressing roller 41.
[0059] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
