Description

Technical Field

[0001] This invention relates to the field of soil mulching technology for saline-alkali land, specifically a new type of soil mulching machine for saline-alkali land. Background Technology

[0002] Soil mulching in saline-alkali land is an effective soil improvement technique. Its core benefits lie in significantly improving the soil environment through physical barriers and ecological regulation. Specifically, mulching inhibits soil moisture evaporation, reducing the amount of salt rising to the surface with water, thereby lowering the salt concentration in the topsoil and alleviating salinization. Simultaneously, mulching increases soil temperature, promoting seed germination and seedling growth, making it particularly suitable for crops planted in early spring or late autumn. Furthermore, mulching has excellent water retention, reducing water loss and improving water resource utilization efficiency, making it especially suitable for arid regions. It also suppresses weed growth, reducing herbicide use, lowering production costs, and minimizing environmental pollution. Long-term mulching can also improve soil structure, prevent compaction, enhance soil aeration and permeability, promote microbial activity, and improve soil fertility.

[0003] Traditional mulching machines are ill-suited to the compacted and heavy characteristics of saline-alkali soils, often resulting in uneven mulching and film damage. Existing mulching machines typically use tractors as power sources, but tractors have limitations in their operating environment; they often cannot operate in low-lying areas. Furthermore, existing mulching machines often fail to perfectly complete the mulching process because incomplete mulching areas require manual re-checking and patching. For example, Chinese patent application number 202411632149.1 discloses a mulching machine and its method for using in saline-alkali soils used for rice and wheat cultivation, including a support cylinder. The device has symmetrical outer shells fixedly connected at both ends. One end of a film roller frame is fixedly connected to the middle side wall of the outer shell, and a traction frame is rotatably installed on the crossbar of the film roller frame. It also includes a support frame, the connecting plate at the top of which is fixedly installed on the outer wall of the outer shell. A wheel ring is coaxially rotatably sleeved on the disc at the bottom of the support frame, and a toothed ring is fixedly installed on the inner wall of the wheel ring. Although the above technical solution can ensure a certain amount of soil collection through the soil collection mechanism, due to the movement mode of the soil collection mechanism and the unevenness of the loose soil in the working site, it is possible that the soil collection mechanism will not be able to collect soil, resulting in a smaller amount of soil for subsequent mulching and requiring manual intervention.

[0004] To address the aforementioned problems, this invention provides a novel soil mulching machine for saline-alkali land, capable of achieving efficient, precise, and multifunctional mulching operations. Summary of the Invention

A mulch film roller 6 is placed between the two mulch film installation grooves 5. A mulch film 7 is fixedly installed on the outside of the mulch film roller 6. The mulch film inner roller 8 is used to guide the mulch film 7.

[0048] The frame 203 has a flat plate that is perpendicular to the partition plate 206 inside.

[0049] In this embodiment, the frame 203 is connected to the partition plate 206 by welding. The partition plate 206 divides the frame 203 into spaces. The power moving device 4 is installed in the front space. The main function of the power moving device 4 is to enable the entire equipment to move in the saline-alkali land.

The frame 203 is connected to the top mounting plate 201 by welding, and the top mounting plate 201 is connected to the connecting rod 202 by welding. The main function of the connecting rod 202 is to prevent deformation at the rear end of the frame 203 and to balance the weight of the soil breaking mechanism 3 at the front. The frame 203 is connected to the support rod 204. The connections between the support rods 204 and the support wheel 205 are made by welding. The main function of the support wheel 205 is to support the weight of the earth-breaking mechanism 3. The connection between the support wheel 205 and the frame 203 is also made by bolts.

The ground film roller 6 and the ground film 7 are combined into one piece. The ground film 7 is wrapped around the ground film roller 6. By placing the ground film roller 6 in the ground film installation groove 5, the ground film 7 can rotate. The main purpose of the flat plate perpendicular to the partition plate 206 inside the frame 203 is to place the power moving device 4. The ground film 7 is guided by the inner roller of the ground film 8, so that the ground film 7 is laid directly on the ground.

The low end is parallel to the bottom side of the soil breaking mechanism 3. The soil pressing roller 101 is a roller structure with a support. The length of the roller structure exceeds the distance between the edge of the mulch film 7 and the frame 203.

[0053] The soil covering mechanism 1 also includes a soil pressing roller 101 that is fixedly installed on a plane with the soil covering device 102.

[0054] In this embodiment, the soil covering device 102 is welded to the inner wall of the frame 203. The soil covering device 102 has two openings, one at the top and one at the bottom. By moving the entire device, the broken soil is discharged from the top opening through the bottom opening along the arc shape of the soil covering device 102. The main function of the soil pressing roller 101 is to compact the soil discharged from the soil covering device 102 and covering the mulch film.

The other end of the connecting plate B12 is fixedly installed with the connecting plate C14 by bolt connection. A rib 13 is also provided between the connecting plate B12 and the connecting plate C14. The function of the rib 13 is to further enhance the structural strength between the connecting plate B12 and the connecting plate C14 and prevent deformation or breakage caused by external load or vibration. The rib 13 is usually made of the same material as the connecting plate and is fixed by evenly distributed welding points or bolts to ensure that its connection with the connecting plate B12 and the connecting plate C14 is firm and reliable.
