[0002] Nowadays, there are three main types of soil covering and pressing wheels: figure eight plate type, double disc type and extrusion type.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Example

[0032] Please refer to Figure 1-Figure 9 The present embodiment provides a soil covering, suppressing and entropy preservation device, comprising a wheel mounting assembly and soil covering and suppressing wheels 1 rotatably arranged on both sides of the wheel mounting assembly, a buffer assembly is provided on the top of the wheel mounting assembly, and a connecting piece 2 is fixedly provided on the buffer assembly; it also comprises an inclined mounting plate 3 and a compacting wheel 4 rotatably arranged at the bottom of the mounting plate 3; the top of the mounting plate 3 is rotatably arranged on the connecting piece 2, and a tension spring 5 is provided between the mounting plate 3 and the wheel mounting assembly; one end of the tension spring 5 is connected to the wheel mounting assembly, and the other end of the tension spring 5 is movably connected to the mounting plate 3.

[0033] Two clamping plates 6 are arranged opposite to each other on the upper side walls of the mounting plate 3, and a plurality of clamping grooves 7 are arranged at intervals along the extending direction of the clamping plates 6, and a through hole 8 is arranged on the upper side wall of the mounting plate 3; a clamping rod 9 is arranged at one end of the tension spring 5 close to the mounting plate 3, and the clamping rod 9 passes through the through hole 8 and is clamped in a clamping groove 7.

[0034] The buffer assembly includes a piston cylinder 11 fixed to the wheel mounting assembly and a piston 12 slidably arranged in the piston cylinder 11. A piston rod 13 is arranged on the top of the piston 12, and the piston rod 13 slides through the piston cylinder 11.

[0035] The piston 12 divides the interior of the piston cylinder 11 into a rebound chamber 14 and a compression chamber 15. The rebound chamber 14 is located above the compression chamber 15. The rebound chamber 14 and the compression chamber 15 are filled with damping fluid 16. The piston 12 is provided with a connecting hole 17 connecting the rebound chamber 14 and the compression chamber 15. The connecting member 2 is fixed to the piston cylinder 11. The connecting member 2 of this embodiment is in a U shape, with both ends fixed to the piston cylinder 11 and the other side rotating through the mounting plate 3. The piston rod 13 is sleeved with a buffer spring 18, which is located in the rebound chamber 14. One end of the buffer spring 18 is connected to the piston cylinder 11, and the other end of the buffer spring 18 is connected to the piston 12.

[0036] In actual use, the soil covering and pressing entropy preservation device provided by the present application is installed on a seed drill for use. During installation, the piston rod 13 is fixedly installed on the seed drill. In use, the soil covering and pressing wheel 1 and the compacting wheel 4 are in contact with the ground and compact the ground as the seed drill moves. The soil covering and pressing wheel 1 is used for the second soil covering, and the compacting wheel 4 is used for the third soil covering and maintaining the stability of soil moisture.

[0037] The buffer assembly can be used to alleviate the impact caused by the road surface, quickly absorb the vibration caused by the bumps of the soil covering and suppressing entropy preservation device, and restore the soil covering and suppressing wheel 1 to a normal state. During vibration, the soil covering and suppressing wheel 1, the wheel mounting assembly and the piston cylinder 11 move upward together. Since the piston rod 13 is fixed to the seed drill, the piston cylinder 11 moves upward relative to the piston rod 13, and the piston 12 moves downward relative to the piston cylinder 11. At this time, the compression chamber 15 is squeezed smaller, and the damping fluid 16 in the compression chamber 15 flows into the rebound chamber 14 through the connecting hole 17, and the buffer spring 18 becomes longer, so that the vibration can be buffered. After the buffering is completed, the piston 12 can be pulled to move and reset under the pulling force of the buffer spring 18. At this time, it is convenient for the buffer assembly to reset as a whole and wait for the next buffering.

[0038] The mounting plate 3 of the present application is tilted, and a triangular structure is roughly formed between the mounting plate 3, the tension spring 5 and the buffer assembly, so that the length of the tension spring 5 can be adjusted to adjust the pressing strength of the compacting wheel 4. During adjustment, when the pressing strength of the compacting wheel 4 needs to be increased, the clamping rod 9 is moved toward one side of the compacting wheel 4 and clamped in the clamping groove 7 at the corresponding position. The farther the clamping rod 9 is clamped, the greater the length of the tension spring 5 is stretched. At this time, the greater the tension applied by the tension spring 5 to the mounting plate 3 and the wheel mounting assembly, the greater the downward pressure of the compacting wheel 4 on the soil, that is, the greater the pressing strength.

[0039] In this way, the present application can more reasonably achieve soil covering and compaction, apply precise compaction force according to the soil moisture conditions, increase the density and firmness of the soil, improve the operating performance of the compaction device, maintain the stability of the soil moisture conditions, and provide suitable growth conditions for seeds.

The utility model provides the scraping plate 10, which is used to scrape the soil on the compacting wheel 4 to keep the compacting wheel 4 able to operate stably.

[0041] like Figure 1-Figure 9 As shown, in some embodiments of the utility model, the above-mentioned wheel mounting assembly includes a fixing seat 19 and two mounting balls 20 rotatably embedded in the fixing seat 19, and the mounting balls 20 are provided with an axle 21; the soil covering and pressing wheel 1 is rotatably arranged on the axle 21 through a bearing 22; the fixing seat 19 is provided with a mounting ring 25, and one end of the tension spring 5 close to the wheel mounting assembly is connected to the mounting ring 25.

[0042] An adjusting ball 23 is rotatably provided in the fixing seat 19, and the adjusting ball 23 is located between the two mounting balls 20. A connecting rod 24 is fixedly provided between any mounting ball 20 and the adjusting ball 23; the connecting rods 24 on both sides are coaxial and the axis line of the connecting rod 24 passes through the center of the adjusting ball 23 and the center of the two mounting balls 20; the axle 21, the mounting ball 20 and the connecting rod 24 form a V shape.

[0043] An adjustment hole 26 connected to the adjustment ball 23 is provided on the side wall of the fixing seat 19, and the adjustment hole 26 is a strip-shaped hole; an adjustment rod 27 is fixedly provided on the adjustment ball 23, and the adjustment rod 27 passes through the adjustment hole 26; an outer wall of the adjustment rod 27 is provided with an external thread, and a locking nut 28 is threadedly connected to the outer wall of the adjustment rod 27; the locking nut 28 is located outside the adjustment hole 26, and the outer diameter of the locking nut 28 is greater than the width of the adjustment hole 26, and the locking nut 28 abuts against the outer wall of the fixing seat 19.

[0044] The utility model provides a wheel mounting assembly, because the axle 21, the mounting ball 20 and the connecting rod 24 form a V shape, so that Figure 1 and Figure 2As shown, the planes where the two soil covering and pressing wheels 1 are located form an angle, so that when covering the soil for the second time, the two soil covering and pressing wheels 1 can be adjusted to different angles for soils with different moisture conditions to increase the density and firmness of the soil and achieve the effect of stabilizing the soil moisture conditions. When adjusting, the locking nut 28 can be rotated and loosened, and the adjusting rod 27 can be moved by hand along the extension direction of the adjusting hole 26, and the adjusting ball 23 can be driven to rotate by the adjusting rod 27, and the two mounting balls 20 on both sides can be driven to rotate under the drive of the connecting rod 24, so as to drive the axles 21 on both sides to rotate, so as to drive the two soil covering and pressing wheels 1 to rotate to adjust their angles, which is easy to operate.
