Description

Technical Field

[0001] This utility model relates to the field of soil improvement technology, specifically to a soil improvement equipment for saline-alkali land. Background Technology

[0002] Against the backdrop of global warming, intensified human activities, and climate change, soil salinization has become increasingly severe, posing a significant challenge to sustainable agricultural development. International research on deep tillage encompasses biological, chemical, and mechanical methods. Mechanical deep tillage is a mature technology, with well-developed theories and systematic operational techniques. New types of deep tillage machinery, such as side-curved blade deep tillers, vibratory deep tillers, and functional deep tillage shovels, each have their own unique characteristics. Furthermore, there are machines that combine deep tillage, land preparation, and sowing, improving work efficiency. In the United States, lawn aerators can break and compact tough soil, increasing air and water movement and improving fertilizer utilization. In recent years, the research and development of deep tillage components and implements in China has attracted attention, and deep tillage implements suitable for different regions have been developed. However, compared with foreign countries, there are challenges in terms of material quality, resistance and matching power. Most of them adopt a combined tillage method consisting of rotary tillers, plows, harrows and furrow openers. Moreover, some mechanical equipment has problems such as high load operation and poor adaptability to terrain. For example, large machinery is restricted in some northern regions, and small agricultural machinery is difficult to use in mountainous areas. Furthermore, existing equipment is difficult to effectively retain rain and snow and is prone to damaging the plow pan, leading to soil compaction.

[0003] Existing machinery struggles to address issues like soil compaction and shallow topsoil, impacting soil improvement effectiveness and agricultural productivity. Currently, China employs a combination of traditional agricultural techniques and engineering measures to increase soil moisture content. Firstly, most machinery operates under high loads, necessitating the use of large to medium-sized tractors and corresponding agricultural equipment. Small agricultural machinery, due to its portability, flexibility, and low cost, is also widely used in farmland. However, in northern regions where manual cultivation is limited and the geographical complexity restricts access, large machinery is not the primary choice for farmers. Furthermore, the rugged terrain and difficult roads in mountainous areas render some small agricultural machinery unusable. Moreover, current machinery struggles to effectively retain remaining rain and snow, damaging the plow pan and leading to soil compaction and a shallow topsoil, both of which negatively affect the efficiency of soil improvement operations.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 5This utility model provides a technical solution: a soil improvement equipment for saline-alkali land, including a box body 1 and a frame 2. The box body 1 is located above the frame 2, and two moving wheels 3 are installed at the bottom of the frame 2. The side wall of the box body 1 has a discharge port. The box body 1 is also equipped with: an excavating mechanism 4, a conveying box 5, a fertilizer conveying mechanism, a soil conveyor belt 6, a mixing mechanism, and an output mechanism. The excavating mechanism 4 is installed at the top of the box body 1; the conveying box 5 is located at the top of the box body 1, and the bottom outlet of the conveying box 5 is connected to the inside of the box body 1; the fertilizer conveying mechanism is installed inside the box body 1 and located at the bottom of the conveying box 5; the soil conveyor belt 6 is installed on the side of the box body 1, and a conveying motor 7 is connected to the soil conveyor belt 6; the mixing mechanism is located inside the box body 1 and located below the fertilizer conveying mechanism; the output mechanism is installed at the bottom of the inside of the box body 1 and located below the mixing mechanism.

[0020] It should be noted that when mixing saline-alkali soil with fertilizer, the worker connects the end of the frame 2 to the agricultural vehicle. First, the worker pours the fertilizer into the feed inlet of the conveyor box 5. Guided by the fertilizer conveying mechanism, the fertilizer enters the box 1 evenly. At this time, the mixing mechanism starts to rotate, and the worker operates the excavating mechanism 4. The excavating mechanism 4 can use the existing excavating arm and the bucket of the excavating wall to dig the ground soil. After the excavation is completed, the worker controls the bucket to pour the soil into the soil conveyor belt 6. Then, the conveying motor 7 is powered on and rotates. After being slowed down by the reducer connected to the conveying motor 7, it drives the roller of the soil conveyor belt 6 to rotate. The soil conveyor belt 6 is driven by the friction between the roller and the soil conveyor belt 6, and the soil conveyor belt 6 lifts the soil upward and finally pours it into the box 1. Immediately afterwards, the mixing mechanism is powered on and rotates to fully mix the fertilizer conveyed by the fertilizer conveying mechanism and the soil delivered by the excavating mechanism 4 through the soil conveyor belt 6. After mixing is complete, the output mechanism begins to rotate, thus conveying the mixed soil-fertilizer mixture outward from the discharge port on the side wall of the container 1, completing the unloading operation. When the soil and fertilizer near the frame 2 have finished mixing, the frame 2 and container 1 are moved forward by the forward traction of the agricultural vehicle, and then the mixing operation continues for the next location of soil and fertilizer. This cycle is repeated to achieve the improvement of saline-alkali soil.

[0021] In some examples, the mixing mechanism includes a stirring motor 8 and a spiral stirring shaft 9. The stirring motor 8 is mounted on the outside of the housing 1 and the drive end extends to the inside of the housing 1. One end of the spiral stirring shaft 9 is fixedly mounted on the drive end of the stirring motor 8 and the other end is rotatably mounted on the side wall of the housing 1.

[0022] It should be noted that during the mixing and stirring of saline-alkali soil and fertilizer, the stirring motor 8 installed on the outside of the housing 1 is powered on and started, and its drive end immediately begins to rotate. Since one end of the spiral stirring shaft 9 is firmly fixed to the drive end of the stirring motor 8, the rotation of the stirring motor 8 drives the spiral stirring shaft 9 to rotate together, powerfully and thoroughly mixing the fertilizer conveyed by the fertilizer conveying mechanism above and the soil excavated by the excavating mechanism 4 and then conveyed by the soil conveyor belt 6, ensuring that the fertilizer and soil are evenly mixed, providing a high-quality mixture foundation for subsequent soil improvement operations. In terms of fertilizer conveying, the mixing and stirring mechanism can evenly spread the fertilizer on the inside of the housing 1, achieving a large power transmission and ensuring stable and efficient fertilizer conveying.

[0023] In some examples, the fertilizer conveying mechanism includes a conveying auger 10 and a linkage assembly. The conveying auger 10 is rotatably disposed at the bottom of the conveying box 5. The linkage assembly is installed on the outside of the box 1 and is connected to the stirring motor 8 and the conveying auger 10 respectively.

[0024] It should be noted that when the saline-alkali land soil improvement operation is started, the fertilizer conveying mechanism operates simultaneously. The mixing motor 8 is powered on first. Since the linkage component is installed on the outside of the housing 1 and is connected to both the mixing motor 8 and the conveying auger 10, when the mixing motor 8 rotates, the transmission action of the linkage component drives the conveying auger 10 to start rotating at the bottom of the conveying housing 5. At this time, the worker pours fertilizer into the conveying housing 5 through the fertilizer inlet. As the conveying auger 10 continues to rotate, it pushes the fertilizer downwards in an orderly manner, spreading it evenly in the mixing area formed between the housing 1 and the spiral mixing shaft 9. This prepares sufficient materials for subsequent mixing with the soil excavated by the excavation mechanism 4 and conveyed by the soil conveyor belt 6, ensuring that the entire soil improvement operation can proceed smoothly and efficiently.

[0025] In some examples, the linkage components include: a housing 11, sprockets 12, and a chain 13. The housing 11 is located on the outer side of the outer wall of the housing 1, and its two ends are respectively located between the stirring motor 8 and the conveying auger 10. The two sprockets 12 are located inside the housing 11 and are respectively mounted on the end of the conveying auger 10 and the drive end of the stirring motor 8. The chain 13 is mounted on the two sprockets 12.

[0026] It should be noted that when the soil improvement operation of saline-alkali land is started, when the mixing motor 8 is powered on and its drive end starts to rotate, the sprocket 12 installed on the drive end of the mixing motor 8 rotates synchronously. As the sprocket 12 on the drive end of the mixing motor 8 rotates, the chain 13, as the link of operation, drives the sprocket 12 fitted on the end of the conveying auger 10 to rotate as well. This causes the conveying auger 10 to rotate flexibly at the bottom of the conveying box 5, continuously pushing the fertilizer poured into the conveying box 5 to the designated position. This works closely with the subsequent processes to ensure that the entire soil improvement operation is smooth and unobstructed. The shell provides protection and support for the internal chain 13 and sprocket 12.

[0027] In some examples, the output mechanism includes: a mounting frame 14, a discharge motor 15, and a conveyor belt 16. The mounting frame 14 is located at the bottom inner side of the housing 1; the discharge motor 15 is located on the side of the mounting frame 14; and the conveyor belt 16 is rotatably located inside the mounting frame 14 and connected to the drive end of the discharge motor 15.

[0028] It should be noted that after the saline-alkali soil and fertilizer are fully mixed and stirred inside the container 1, the discharge motor 15 starts to operate. After being slowed down by the reducer connected to the discharge motor 15, it drives the rollers of the conveyor belt 16 to rotate. The conveyor belt 16 is driven to rotate by the friction between the rollers and the conveyor belt 16. Under the drive of the conveyor belt 16, the well mixed soil and fertilizer mixture gradually moves outward from the discharge port on the side wall of the container 1, completing the unloading operation smoothly and efficiently. This makes room for the subsequent tractor to move the equipment forward to continue the next soil improvement operation, ensuring that the entire saline-alkali soil improvement process can proceed continuously and smoothly.

[0029] In some examples, the inner side of the housing 1 is provided with two inclined guide plates 17, with an open opening above the two guide plates 17 and a contraction opening below them, the contraction opening being located directly above the conveyor belt 16.

[0030] It should be noted that when the mixing and stirring stage is completed and the unloading operation is about to begin, the mixed soil-fertilizer mixture will first fall into the open area above the two guide plates 17 under the influence of gravity. The mixture will then slide down the inclined surface of the guide plates 17. Guided by the guide plates 17, the originally dispersed mixture will gradually gather towards the center and finally fall neatly onto the conveyor belt 16 through the contraction opening below. Immediately afterwards, the conveyor belt 16 will start to rotate under the drive of the discharge motor 15, smoothly and efficiently conveying the mixture that has fallen onto it from the discharge port on the side wall of the housing 1, completing the unloading process and ensuring that the entire equipment can smoothly carry out the next soil improvement task.
