[0015] The beneficial effects of the application are as follows:

[0016] The grid format tamping mechanism is dragged forward by the frame and generates rotating power through friction with the ground during walking, and the grid format tamping mechanism tamps the rotary tillage ground by using the weight of the machine and outputs the rotating power to the driving sprocket;

[0017] The grid format tamping mechanism of the fertilizer rotary tillage machine is provided with a driving pressure increasing structure, a plurality of grid bars are fixedly installed on the outer sides of the four groups of adjusting arc plates in the same axial position, so as to form a grid cylinder and realize the leakage of excess sand from the grid, avoid the soil accumulation phenomenon, and the sliding installation structure of each group of adjusting arc plates can realize the following functions: in the working process, the corresponding pressure spraying mechanism is started, under the pushing effect of the pneumatic telescopic cylinder, the local grid structure composed of the adjusting arc plate and the connected grid bar is provided with pressure, so that the local grid structure in contact with the ground is increased in pressure and moves downward, thereby greatly improving the compaction capacity of the soil after tillage.

[0018] In the grid format tamping mechanism of the fertilizer rotary tillage machine, the water mist spraying structure is provided, in the process of tillage and fertilization, the conventional tillage and tamping structure cannot effectively ensure the stable covering relationship of soil, fertilizer and seeds, and additional spraying is needed after tillage to improve soil humidity and fertilizer soil absorption effect, and the use of mobile equipment spraying process may cause secondary compression of soil and seeds, in the present application, through the setting of a plurality of pressure adjusting arc plates, the outer adjusting arc plate can be tamped with the grid bar at the same time, water flow is input from the water mist spraying plate to the outside through the water mist supply device, the grid structure does not affect the spraying effect and can form a flushing effect inside the grid for maintenance, the water mist spraying and grid tamping effect can further greatly improve the stable covering relationship among soil, fertilizer and seeds, and provide a germination environment for seeds and improve soil humidity and fertilizer soil absorption effect, thereby optimizing the fertilizer absorption effect and improving the tillage and fertilization efficiency.

[0019] In the grid-type compaction mechanism of the rotary tillage and fertilization machine of the present invention, multiple sets of grid bars arranged in a circular array with left and right symmetry are used to form an adjustable grid-type compaction outer contour. Combined with the internal functional structure, this design avoids the influence of ground environmental factors on the compaction effect and further improves the rotary tillage, fertilization, and land preparation effect and efficiency. Conventional roller-type compaction mechanisms or grid-type compaction structures, due to their fixed installation mode of the roller or grid outer contour, are susceptible to ground environmental influences during actual tillage, fertilization, and compaction processes, such as unevenness of the land on both sides, inconsistent height, and encountering stones. The uneven height of the two sides of the compaction roller can lead to ineffective compaction of certain sections of the land surface due to variations in support and tilt angle, sometimes even resulting in areas that are suspended and unable to be compacted. In the grid-type compaction mechanism of this invention, the outer contour of the grid is composed of multiple sets of grid bars arranged in a circular array with symmetrical left and right sides. The grid bars are mounted on an adjustable mounting plate and its outer side is adjustable by a sliding plate. The grid bars are fixed on the outer side of the adjusting plate, and the adjusting plate and the adjusting mounting plate are connected by an adjusting sliding frame, a groove, and a spring. The spring structure enables adjustable and elastic buffering reset functions. During the compaction process, the grid bars outside the same set of adjusting arc plates in contact with the ground retract under contact pressure, thus compacting the ground. Meanwhile, multiple sets of symmetrically distributed grid bars on both sides form relatively independent grid outlines. Therefore, in actual cultivation, fertilization, and compaction processes, this significantly reduces the impact of uneven heights on both sides of the cultivated land, encountering hard supporting objects such as stones, which can cause the integrally fixed roller or grid outline to tilt under support, resulting in reduced contact force with the ground or even suspension and ineffective compaction. The problem is that, in conjunction with the internal active pressurization and water mist spraying structure, it can achieve secondary pressurization during the rolling contact process. While the pressurizing structure performs its pressurizing function, it can also output water mist to the surrounding soil before ground contact and during ground contact pressurization through the grid gaps, thereby improving the fertilizer dissolution effect on the soil. Furthermore, the secondary pressurization function and the water mist effect complement each other, which can further greatly improve the stable covering relationship between soil, fertilizer and seeds, improve the stability of the three after soil covering, and further optimize the actual functional effect of fertilization on soil and seeds due to the better soil dissolution factor of fertilizer.

[0043] Working principle of the rolling device:

[0044] In the fertilizer rotary tillage land preparation machine, the grid format rolling mechanism 10 is arranged and pulled forward by the machine frame 11, and rotation power is generated by friction with the ground during walking, the grid format rolling mechanism 10 performs rolling operation on the rotary tillage ground by using the weight of the machine, and outputs the rotation power to the driving sprocket 86.

[0045] In the grid format of the fertilizing rotary tillage machine's tamping mechanism 10, the active pressurization structure is provided, the same side adjacent two groups of adjusting arc plates 41 in the same axial position are commonly welded and fixedly installed with multiple groups of grid bars 43, so that the grid cylinder is formed to leak the excess sand from the grid, and the soil blocking phenomenon is avoided, and the sliding installation structure of each group of adjusting arc plates 41 can realize that, in the operation process, the corresponding pressure spraying mechanism 30 is started, under the pushing effect of the pneumatic telescopic cylinder 31, the partial grid structure formed by the adjusting arc plate 41 and the grid bar 43 connected with the adjusting arc plate 41 is provided with pressure, so that the partial grid structure in contact with the ground is pressurized and lowered, and the compaction capacity of the soil after tillage is greatly improved.

[0046] In the grid format of the fertilizing rotary tillage machine's tamping mechanism 10, the water mist spraying structure is provided, in the tillage and fertilization process, the conventional tillage and tamping structure cannot effectively guarantee the stable covering relationship of soil, fertilizer and seeds, and additional spraying is needed after tillage to improve soil humidity and fertilizer absorption and dissolution effect, and the soil and seeds may be secondarily compressed in the spraying process of the mobile device, in the present application, in the tillage and fertilization tamping process, through the setting of multiple groups of pressure adjusting arc plates 32, the outer adjusting arc plate 41 can be matched with the grid bar 43 for tamping, water flow is input from the water mist spraying plate 33 to the outside through the water mist supply device, the grid structure does not affect the spraying effect and can form flushing inside the grid for maintenance, the water mist spraying matched with the grid tamping effect can further greatly improve the stable covering relationship among soil, fertilizer and seeds, and provide a germination environment for the seeds through the water mist, improve soil humidity and fertilizer dissolution effect, so as to optimize the fertilizer application and absorption effect, improve the tillage and fertilization efficiency.

[0047] In the grid format pressing mechanism 10 of the fertilizing rotary tiller of the application, the grid outer contour composed of the left and right symmetrical multiple groups of grid bars 43 arranged in a ring array can avoid the influence of ground environmental factors on the pressing effect and further improve the rotary tillage, fertilization and soil consolidation effect and efficiency. The conventional drum type pressing mechanism or grid format pressing structure has a fixed installation and mounting mode, so that in the actual tillage, fertilization and pressing process, the height of the pressing drum on both sides is inconsistent due to the ground environmental factors such as the unevenness of the land on both sides and the height inconsistency and the problem of encountering stones, so that the part of the land surface passed through cannot be effectively pressed due to the support and inclination angle, and even cannot be pressed in contact. In the grid format pressing mechanism in the application, the grid outer contour is composed of the left and right symmetrical multiple groups of grid bars 43 arranged in a ring array, and the mounting function of the multiple groups of grid bars 43 is realized by adjusting the mounting plate 40 and the outer side of the stress-sliding adjustable adjusting arc plate 41, the grid bar 43 is mounted and fixed outside the adjusting arc plate 41, and the adjusting arc plate 41 and the adjusting mounting plate 40 realize the adjustable and elastic buffer reset function through the adjusting sliding frame 42 cooperating with the groove and spring structure. In the pressing process, the grid bars 43 outside the adjusting arc plate 41 of the same group in contact with the ground are retracted under the contact pressure and realize the pressing on the ground, and the multiple groups of grid bars 43 symmetrically distributed on both sides form two relatively independent grid outer contours, so that in the actual tillage, fertilization and pressing process, the problem of the height inconsistency of the land on both sides, the problem of encountering hard supporting objects such as stones and other problems can be greatly reduced, so that the drum or grid contour in the whole fixed distribution is supported and inclined, the contact force with the ground is reduced, and even the problem of hanging in the air cannot be effectively pressed in contact. At the same time, the function structure of the internal active pressurization and water mist spraying can realize the re-pressing in the rolling contact process, the start of the active pressurization structure in the middle can realize the synchronous active pressurization of the two sides of the grid outer contour structure, which can reduce the problem of the height inconsistency of the land on both sides caused by the softness of the land and improve the soil consolidation effect. The pressurization structure plays a pressurization function, and the grid gap can output water mist to improve the soil dissolving effect of the fertilizer before the ground contact and during the ground contact and pressurization process, and the secondary pressurization function and the water mist effect can further improve the stable covering relationship among the soil, the fertilizer and the seed, improve the stability among the three after the soil covering, and further optimize the actual function effect of the fertilizer on the soil and the seed.
