Description

Technical Field

[0001] This invention relates to the field of soil loosening and sowing technology, and in particular to a soil loosening and reseeding machine for the treatment and restoration of degraded grasslands through mixed sowing of various forage grasses. Background Technology

[0002] The restoration and management of degraded grasslands is an important issue in ecological and environmental protection. Long-term overgrazing, drought and other factors have led to soil compaction and a decline in vegetation coverage. Planting a single type of forage grass can easily lead to insufficient ecological stability. Therefore, the mixed sowing of multiple forage grasses has become the mainstream management method. Mixed sowing can improve grassland productivity and stress resistance through the complementary root systems and synergistic nutrient utilization of different forage grasses.

[0003] The soil loosening and reseeding machine is the core equipment for realizing this model. It needs to simultaneously loosen the soil and accurately sow forage seeds, creating favorable water, air, and fertilizer conditions for seed germination. However, most existing soil loosening and reseeding machines have a fixed structure, which cannot adapt to the complex terrain of degraded grasslands where "soft depressions and hard compacted areas coexist." When the soil is soft, the loosening area is limited, and when the soil is hard, it is difficult to break through the compacted layer. The sowing mechanism and the soil loosening mechanism lack linkage and adaptability, and cannot dynamically adjust the number of sowing units according to the loosening area, which easily leads to the problem of "low sowing efficiency when the loosening area is large and seed waste when the loosening area is small." In addition, existing equipment is difficult to balance the accuracy and efficiency of mixed sowing of multiple forage grasses, which restricts the effectiveness and large-scale promotion of degraded grassland management and restoration.

[0004] To address the aforementioned problems, this invention proposes various soil loosening and reseeding machines for the treatment and restoration of degraded grasslands through mixed pasture sowing. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing soil loosening and reseeding machines, which are mostly fixed structures, have limited loosening area when the soil is soft, and are difficult to break through the compacted layer when the soil is hard; the sowing mechanism and the soil loosening mechanism lack linkage and adaptability, and cannot dynamically adjust the number of sowing units according to the loosening area. Therefore, this invention proposes a soil loosening and reseeding machine for the treatment and restoration of degraded grasslands by mixed sowing of forage grasses.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A soil loosening and reseeding machine for treating and restoring degraded grasslands by mixed sowing of multiple forage grasses includes a sowing mechanism, on which a soil loosening mechanism is provided;

[0008] The sowing mechanism includes an upper support, on which two sowing adjustment components are provided. The two sowing adjustment components and the upper support are respectively connected to three sowing components. A sowing switch is provided below each sowing component.

[0009] The soil loosening mechanism includes a lifting assembly, three soil loosening components, two soil loosening adjustment components, and two drive assemblies. Racks are fixedly connected to both sides of the fixed plate of the lifting assembly, and movable plates are provided on both sides of the lifting assembly. An arc-shaped rack is fixedly connected above the movable plates. Through the meshing of the second gear of the drive assembly with the arc-shaped rack, the two outer soil loosening components rotate alternately to the front and rear sides of the middle soil loosening component. Simultaneously, the first gear of the soil loosening adjustment assembly drives the racks, causing the soil loosening adjustment components to be distributed in a stepped manner.

[0010] Preferably, the seeding adjustment component includes an installation component, which is fixedly connected to the upper support. An electric push rod is fixedly installed on the installation component, and one end of the electric push rod is fixedly connected to a connector.

[0011] Preferably, the sowing assembly includes a sowing shell, one of which is fixedly connected to the upper support. Multiple sowing openings are provided below the sowing shell, and one end of two of the sowing shells and both ends of the other sowing shell are equipped with umbrella teeth, which mesh with each other between adjacent umbrella teeth.

[0012] Preferably, both ends of the seeding shell are fixedly connected to rollers, and both rollers are rotatably mounted on the seeding frame via bearings. One of the rollers is fixedly connected to the output shaft of the drive device, and the drive device is mounted on the seeding shell.

[0013] Preferably, the other two seeding racks are fixedly connected to the two connecting pieces respectively, and the upper part of the other two seeding racks is provided with a sliding groove, the sliding groove is slidably connected to the sliding strip, and the sliding strip is fixedly connected to the upper support.

[0014] Preferably, the sowing switch includes two guide rails, which are fixedly connected to the sowing shell. A baffle layer is slidably connected to the two guide rails. The baffle layer has multiple discharge ports. A discharge cylinder is fixedly connected to one side of the baffle layer and is installed on the sowing shell.

[0015] Preferably, the lifting assembly includes a lifting device, which is fixedly mounted on an upper support. A drive frame is fixedly mounted at the bottom of the lifting device, and a fixing plate is fixedly connected to the bottom of the drive frame.

[0016] Preferably, the drive assembly includes a rotary motor, which is fixedly mounted on the drive frame, and the output shaft of the rotary motor is fixedly connected to a second gear.

[0017] Preferably, the soil loosening and adjusting component includes a threaded cylinder, on which a first gear is fixedly installed. The threaded cylinder is rotatably mounted on a movable plate via a bearing, and the threaded cylinder is threadedly connected to a screw.

[0018] Preferably, the soil loosening component includes a housing and multiple soil loosening spiral shafts. The two outer housings are hinged to the middle housing via staggered hinges. The housing is fixedly connected to the bottom end of the screw. A telescopic rod is fixedly connected between the housing and the movable plate.

[0019] Multiple soil loosening spiral shafts are rotatably mounted on the housing via bearings. A soil loosening gear is fixedly mounted on the top end of each soil loosening spiral shaft, and multiple soil loosening gears mesh with each other. One end of one of the soil loosening spiral shafts is fixedly connected to the output shaft of a drive motor, which is installed in the housing.

[0020] Compared with existing technologies, this invention provides various soil loosening and reseeding machines for the treatment and restoration of degraded grasslands through mixed pasture sowing, which have the following beneficial effects:

[0021] 1. This multi-grass mixed-seeding replanting machine for treating and restoring degraded grasslands uses a drive component and an arc-shaped rack and pinion transmission to allow the loosening components to be deployed horizontally side by side, increasing the loosening area and improving loosening efficiency. The loosening components can also be vertically merged. At the same time, the loosening adjustment component and rack and pinion transmission can achieve a stepped distribution of the loosening components, forming a "shallow in front and deep in back" loosening mode, reducing the difficulty of loosening and avoiding excessive soil jamming. This method, through the flexible switching settings of the loosening components, meets the loosening needs of soft and hard soils and achieves efficient adaptation to soils of different hardness, improving the targeting and effectiveness of loosening operations on degraded grasslands.

[0022] 2. This multi-forage grass mixed sowing and restoration grassland loosening and reseeding machine features a soil loosening component that, when deployed, can be synchronized with the sowing component by a sowing adjustment component. This allows for dynamic adaptation of the sowing operation, and each sowing component can be loaded with different forage grass seeds, enabling simultaneous mixed sowing of multiple forage grasses and improving sowing efficiency. When the soil loosening component is retracted, only a single sowing component is activated, avoiding waste caused by excessive seed sowing. Simultaneously, the seed discharge rate can be dynamically adjusted based on the soil loosening depth via a sowing switch, ensuring that the seed dispersal amount matches soil fertility, improving seed germination rate, and meeting the "precise and efficient" requirements of multi-forage grass mixed sowing.

[0023] 3. This multi-grass mixed-seeding remediation and restoration machine for degraded grasslands uses a drive component and an arc-shaped toothed rod transmission to enable the loosening component to unfold and switch between steps, meeting the loosening needs under different conditions. For large-area loosening in the unfolded state, the seeding component can be adjusted synchronously through the seeding adjustment component, and the seeding amount can be adjusted through the seeding switch to ensure uniform mixed seeding. In the step-state, concentrated loosening is adapted to the precise sowing of individual seeding components. This allows the equipment to not only complete the sowing task simultaneously during the loosening operation, but also to flexibly adjust the working state of sowing and loosening according to the specific conditions of different degraded grasslands, efficiently completing the loosening and reseeding operation, and significantly improving the equipment's flexibility and adaptability in complex working environments.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Example 1: Refer to Figure 1 and Figures 7-11 A soil loosening and reseeding machine for treating and restoring degraded grasslands by mixed sowing of various forage grasses includes a sowing mechanism 100 and a soil loosening mechanism 200 installed on the sowing mechanism 100.

[0039] The soil loosening mechanism 200 includes a lifting assembly 201, three soil loosening components 205, two soil loosening adjustment components 203, and two drive assemblies 206. The lifting assembly 201 includes a lifting device 2011, which adjusts the vertical position of the soil loosening components 205 to facilitate soil loosening operations. The lifting device 2011 is fixedly mounted on an upper support 101. A drive frame 2012 is fixedly mounted at the bottom of the lifting device 2011, and a fixing plate 2013 is fixedly connected to the bottom of the drive frame 2012. The drive assemblies 206 include a rotary motor 2062, which is fixedly mounted on the drive frame 2012. A second gear 2061 is fixedly connected to the output shaft of the rotary motor 2062. The soil loosening adjustment components... 203 includes a threaded cylinder 2032, on which a first gear 2031 is fixedly installed. By moving the two first gears 2031 in different directions, the first gears 2031 respectively drive the two racks 208 in opposite directions, thereby adjusting one soil loosening component 205 upwards and the other upwards, thus achieving the purpose of stepped distribution. The threaded cylinder 2032 is rotatably mounted on the movable plate 202 through a bearing. The threaded cylinder 2032 can rotate stably through the bearing, so that there is a threaded transmission between the threaded cylinder 2032 and the screw 2033. The threaded cylinder 2032 and the screw 2033 are threadedly connected. Through the transmission between the threaded cylinder 2032 and the screw 2033, the position of the soil loosening component 205 can be adjusted so that the soil loosening can be kept horizontal or switched to a stepped shape.

[0040] Racks 208 are fixedly connected to both sides of the fixed plate 2013 of the lifting component 201. Movable plates 202 are provided on both sides of the lifting component 201. An arc-shaped rack 207 is fixedly connected above the movable plate 202. The arc design of the rack 207 allows it to mesh smoothly with the second gear 2061, enabling the soil loosening component 205 to be adjusted. The second gear 2061 of the drive component 206 meshes with the arc-shaped rack 207, causing the two outer soil loosening components 205 to rotate alternately to the front and rear sides of the middle soil loosening component 205. Simultaneously, the first gear 2031 of the soil loosening adjustment component 203 drives the racks 208, resulting in a stepped distribution of the soil loosening adjustment component 203. The soil loosening component 205 includes a housing 2051 and multiple soil loosening spiral shafts 2054. The two outer housings 2051 are hinged to the middle housing 2051 via staggered hinges. The outer shells 2051 are hinged in an alternating manner, allowing them to maintain a stable forward and backward steering adjustment. The bottom end of the outer shell 2051 is fixedly connected to the screw 2033, and a telescopic rod 204 is fixedly connected between the outer shell 2051 and the movable plate 202. The telescopic feature of the telescopic rod 204 allows the outer shell 2051 to maintain stable up and down movement. Multiple loosening spiral shafts 2054 are rotatably mounted on the outer shell 2051 via bearings. A loosening gear 2053 is fixedly mounted at the top of the loosening spiral shaft 2054, and the multiple loosening gears 2053 mesh with each other. One end of one loosening spiral shaft 2054 is fixedly connected to the output shaft of the drive motor 2052. The drive motor 2052 is installed in the outer shell 2051, and drives the single spiral shaft to rotate. Under the transmission of the meshing of the loosening gears 2053, the loosening spiral shaft 2054 rotates synchronously to perform the loosening operation.

[0041] In this embodiment: the rotary motor 2062 drives the second gear 2061 and the arc-shaped rack 207 to rotate the movable plate 202 and the soil loosening adjustment component 203, thereby allowing the soil loosening component 205 to be deployed horizontally side by side, increasing the soil loosening area and improving the soil loosening efficiency. The soil loosening component 205 can also be vertically merged. At the same time, the first gear 2031 drives the rack 208, and the first gear 2031 drives the threaded cylinder 2032 to rotate. The threaded cylinder 2032 drives the screw 2033 to rotate, thereby adjusting the soil loosening component 205 to achieve a stepped distribution of the soil loosening component 205, forming a "shallow in front and deep in back" soil loosening mode, reducing the difficulty of soil loosening and avoiding soil jamming due to excessive depth. This method, through the flexible switching setting of the soil loosening component 205, meets the soil loosening needs of soft and hard soil, and achieves efficient adaptation to soils of different hardness, improving the targeting and effect of degraded grassland soil loosening operations.

[0042] Example 2: Refer to Figures 2-6A soil loosening and reseeding machine for treating and restoring degraded grasslands by mixed sowing of various forage grasses includes a sowing mechanism 100. The sowing mechanism 100 includes an upper support 101. Two sowing adjustment components 103 are provided on the upper support 101. The sowing adjustment components 103 include mounting parts 1031. The mounting parts 1031 are fixedly connected to the upper support 101. An electric push rod 1032 is fixedly installed on the mounting parts 1031. One end of the electric push rod 1032 is fixedly connected to a connector 1033. The two sowing adjustment components 103 and the upper support 101 are respectively connected to three sowing components 102.

[0043] The sowing assembly 102 includes a sowing shell 1023, which is equipped with a sowing door. Opening the sowing door allows for loading of forage seeds, and closing the door prevents the seeds from spilling. One sowing shell 1023 is fixedly connected to the upper support 101. Multiple sowing openings 1025 are provided below the sowing shell 1023, allowing for the smooth discharge of forage seeds for sowing. Two sowing shells 1023 have bush teeth 106 installed at one end, and the other two ends have bush teeth 106 that mesh with each other, allowing the seeds to spread out between the sowing shells 1023. This design allows the beaded teeth 106 to mesh, enabling the three seeding shells 1023 to rotate synchronously. This facilitates mobile sowing operations and prevents bridging. Both ends of each seeding shell 1023 are fixedly connected to rollers 1024, which are rotatably mounted on the sowing frame 1021 via bearings. The rollers 1024 maintain stable rotation, ensuring the seeding shells 1023 also rotate stably. One roller 1024 is fixedly connected to the output shaft of the drive device 107, allowing the drive device 107 to drive the roller 1024 to rotate, which in turn drives the seeding shells 1023 to rotate. Sowing can then be performed through the sowing port 1025. The drive device 107 is installed on the sowing shell 1023. Two other sowing frames 1021 are fixedly connected to two connecting parts 1033 respectively. Each of the other two sowing frames 1021 has a sliding groove 1022 on its upper surface. The sowing frame 1021 can slide smoothly on the slide bar 104 through the sliding groove 1022, thus ensuring stable adjustment of the sowing frame 1021. The sliding groove 1022 and the slide bar 104 are slidably connected. The slide bar 104 is fixedly connected to the upper support 101. A sowing switch 105 is located below the sowing assembly 102. It includes two guide rails 1052, which guide the material retaining layer 1051 to slide stably. The two guide rails 1052 are fixedly connected to the seeding shell 1023. The material retaining layer 1051 is slidably connected to the two guide rails 1052. The material retaining layer 1051 has multiple discharge ports 1054. By moving the material retaining layer 1051, the degree of misalignment between the discharge ports 1054 and the seeding port 1025 can be adjusted, thereby smoothly adjusting the seeding amount. A discharge cylinder 1053 is fixedly connected to one side of the material retaining layer 1051 and is installed on the seeding shell 1023.

[0044] In this embodiment: when the soil loosening component 205 is deployed, the electric push rod 1032 extends to control the synchronous deployment of the sowing component 102, realizing dynamic adaptation of the sowing operation. Each sowing component 102 can be loaded with different forage seeds, realizing the synchronous mixed sowing of multiple forages and improving sowing efficiency. When the soil loosening component 205 is retracted, only a single sowing component 102 is activated, avoiding waste caused by excessive seed sowing. At the same time, according to the dynamic adjustment of the soil loosening depth, the position of the baffle layer 1051 can be adjusted by the discharge cylinder 1053, so that the staggered opening of the discharge port 1054 and the sowing port 1025 can be adjusted, thereby adjusting the seed discharge rate to ensure that the seed sowing amount matches the soil fertility, improve the seed germination rate, and meet the "precise and efficient" requirements of mixed sowing of multiple forages.

[0045] Example 3: Reference Figures 1-3 and Figures 7-9 A soil loosening and reseeding machine for treating and restoring degraded grassland by mixed sowing of multiple forage grasses includes a sowing mechanism 100. The sowing mechanism 100 includes an upper support 101. Two sowing adjustment components 103 are provided on the upper support 101. The two sowing adjustment components 103 and the upper support 101 are respectively connected to three sowing components 102. A sowing switch 105 is provided below the sowing components 102.

[0046] The soil loosening mechanism 200 includes a lifting assembly 201, three soil loosening components 205, two soil loosening adjustment components 203, and two drive assemblies 206. The fixed plate 2013 of the lifting assembly 201 is fixedly connected to both sides of the fixed plate 2013, and movable plates 202 are provided on both sides of the lifting assembly 201. An arc-shaped rack 207 is fixedly connected to the top of the movable plate 202. The second gear 2061 of the drive assembly 206 meshes with the arc-shaped rack 207 to drive the two outer soil loosening components 205 to rotate alternately to the front and rear sides of the middle soil loosening component 205. At the same time, the first gear 2031 of the soil loosening adjustment component 203 drives the rack 208 to make the soil loosening adjustment component 203 have a stepped distribution.

[0047] In this embodiment, the loosening component 205 is deployed and switched between stepped configurations via the drive component 206 and the arc-shaped toothed rod 207 to meet the loosening needs under different conditions. For large-area loosening in the deployed state, the sowing component 102 can be adjusted synchronously via the sowing adjustment component 103, and the sowing amount can be adjusted via the sowing switch 105 to ensure uniformity of mixed sowing. In the stepped state, the concentrated loosening is adapted to the precise sowing of a single sowing component 102. This allows the equipment to not only complete the sowing task simultaneously during the loosening operation, but also to flexibly adjust the working state of sowing and loosening according to the specific conditions of different degraded grasslands, efficiently completing the loosening and reseeding operation, and significantly improving the equipment's flexibility and adaptability in complex working environments.

[0048] Working principle: During the unfolding and sowing operation, the rotary motor 2062 drives the second gear 2061 and the arc-shaped rack 207 to drive the arc-shaped rack 207 to rotate the movable plate 202. The movable plate 202 drives the loosening component 205 to rotate through the loosening adjustment component 203, so that the loosening components 205 unfold in a horizontal "I" shape. During the unfolding process, the first gear 2031 and the rack 208 drive the threaded cylinder 2032 and the screw 2033 to drive the screw. At this time, the screw 2033 drives the sowing component 102 to keep it horizontal. At the same time, the electric push rod 1032 is controlled to extend, so that the sowing component 102 unfolds at the same time, and the bush teeth 106 are kept meshed.

[0049] Then, the forage seeds are loaded into the seeding shell 1023, and the drive motor 2052 is operated to drive the loosening spiral shaft 2054 to rotate. Under the transmission of multiple loosening gears 2053, multiple loosening spiral shafts 2054 rotate synchronously, so that this device can cooperate with agricultural machinery to carry out forward loosening operations. The drive device 107 drives the roller 1024 to rotate, and the roller 1024 drives the seeding shell 1023 to rotate. Under the transmission of the bevel gear 106, multiple seeding shells 1023 rotate synchronously. Then, the discharge cylinder 1053 is operated to drive the baffle layer 1051 to move. In this way, the seeding amount can be adjusted by the degree of misalignment between the discharge port 1054 and the seeding port 1025, so that the seeding operation can be carried out during loosening.

[0050] When the seeds are being gathered, the electric push rod 1032 retracts, causing the seeding component 102 to be gathered. At the same time, the rotary motor 2062 reverses, causing the soil loosening component 205 to flip and be gathered. During the gathering process, since the two first gears 2031 drive the two racks 208 in opposite directions, the soil loosening component 205 can be distributed in a stepped manner to carry out soil loosening and seeding operations.

[0051] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
