Description

Technical Field

[0001] This utility model relates to the field of saline-alkali land improvement technology, and in particular to a deep loosening device for saline-alkali land management. Background Technology

[0002] Saline-alkali land severely inhibits agricultural development. When the soil salinity is too high, some plants cannot absorb sufficient water from the soil, leading to seed failure and serious damage to the root system. This prevents the roots from absorbing nutrients and water from the soil, resulting in soil infertility and slowed plant growth. Saline-alkali land not only affects plants but also corrodes timber, copper, and iron, causing damage to roads and buildings. Because saline-alkali soil reduces vegetation cover and exposes the land, it leads to high evaporation rates, resulting in droughts and sandstorms, causing severe damage to the ecological environment.

[0003] Currently, deep tillage operations on saline-alkali land face significant resistance. The deep tillage shovels are prone to soil sticking, and the connecting bolts on the shovels have a short service life, requiring frequent machine shutdowns for replacement. This severely impacts deep tillage operations on saline-alkali land. Furthermore, deep tillage requires the use of high-horsepower agricultural machinery, which has poor environmental adaptability and is unsuitable for deep tillage operations on small plots or plots with obstacles. Additionally, using high-horsepower agricultural machinery for deep tillage operations results in high costs.

[0004] How to provide a deep tillage device for saline-alkali land management that can reduce downtime and maintenance time and be adapted to low-horsepower agricultural machinery for traction deep tillage operations has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a deep tillage device for saline-alkali land treatment, comprising three mounting frames, which are hinged together by hinges.

[0008] The upper surface of the mounting frame is equipped with a hinge lug, which is hinged to the agricultural machinery via a hydraulic rod;

[0009] Limiting wheels are installed at both ends of the lower surface of the mounting bracket, and a deep loosening component is installed in the middle of the lower surface of the mounting bracket.

[0010] Preferably, the subsoil assembly includes a mounting plate, a first subsoil shovel handle, a second subsoil shovel handle, and a third subsoil shovel handle, with the mounting plate equally spaced on the lower surface of the mounting frame;

[0011] The mounting bracket near the agricultural machinery is connected to the first deep tillage shovel handle via the mounting plate and bolts;

[0012] The mounting bracket in the middle is connected to the second deep loosening shovel handle via the mounting plate and bolts;

[0013] The mounting bracket, located away from the agricultural machinery, is connected to the third deep loosening shovel handle via the mounting plate and bolts.

[0014] Preferably, the tips of the first deep loosening shovel handle, the second deep loosening shovel handle, and the third deep loosening shovel handle are equipped with deep loosening shovel heads.

[0015] Preferably, the lengths of the first, second, and third deep loosening shovel handles increase sequentially, and the openings of the first, second, and third deep loosening shovel handles are all arranged in the same straight line.

[0016] Preferably, it also includes a short tillage plate and a long tillage plate, wherein the short tillage plate is fixedly installed on the side wall of the second deep loosening shovel handle, and the long tillage plate is fixedly installed on the side wall of the third deep loosening shovel handle;

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] like Figure 1-5 As shown, a deep tillage device for saline-alkali land treatment includes three mounting frames 2, which are hinged together by hinges 11.

[0029] The upper surface of the mounting frame 2 is equipped with a hinge ear 3, which is hinged to the agricultural machinery via a hydraulic rod.

[0030] Limiting wheels 1 are installed at both ends of the lower surface of the mounting frame 2, and a deep tillage component is installed in the middle of the lower surface of the mounting frame 2. The mounting frame is connected by a hinge, so that when the deep tillage component on the mounting frame moves forward under the drive of the agricultural machinery, the deep tillage component can be embedded into the soil layer of the saline-alkali land to cut and deep tillage the soil layer. Furthermore, the limiting wheels can limit the penetration depth of the deep tillage component, ensuring that the deep tillage component can perform deep tillage operations at a predetermined depth, reducing the workload of the agricultural machinery.

[0031] Specifically, the subsoil assembly includes a mounting plate 4, a first subsoil shovel handle 5, a second subsoil shovel handle 6, and a third subsoil shovel handle 7, with the mounting plate 4 evenly spaced on the lower surface of the mounting frame 2;

[0032] The mounting bracket 2, which is close to the agricultural machinery, is connected to the first deep loosening shovel handle 5 via the mounting plate 4 and bolts;

[0033] The middle mounting bracket 2 is connected to the second deep loosening shovel handle 6 via the mounting plate 4 and bolts;

[0034] The mounting frame 2, which is far from the agricultural machinery, is connected to the third deep loosening shovel handle 7 via the mounting plate 4 and bolts. The tips of the first deep loosening shovel handle 5, the second deep loosening shovel handle 6, and the third deep loosening shovel handle 7 are equipped with deep loosening shovel heads 10. The shovel heads can drive the deep loosening shovel handles to penetrate the salt crust or hardened layer on the surface of the saline-alkali land without the aid of external downward pressure. The first deep loosening shovel handle 5, the second deep loosening shovel handle 6, and the third deep loosening shovel handle 7 are used to carry out deep loosening operations on the saline-alkali land, break up the hard soil layer, and increase the soil porosity.

[0035] Specifically, the lengths of the first deep loosening shovel handle 5, the second deep loosening shovel handle 6, and the third deep loosening shovel handle 7 increase sequentially, and the openings of the first deep loosening shovel handle 5, the second deep loosening shovel handle 6, and the third deep loosening shovel handle 7 are all arranged in the same straight line.

[0036] During operation, the first deep-loosening shovel handle and shovel head loosen the shallower saline-alkali soil layer beforehand. Then, the second deep-loosening shovel handle and shovel head, of medium length, continue to deep-loosen the medium-depth saline-alkali soil layer along the movement trajectory of the first deep-loosening shovel handle and shovel head. The third deep-loosening shovel handle and shovel head follow the same pattern, performing deep-loosening operations in a stepped manner. During the deep-loosening process, the deep-loosening shovel handle experiences relatively little resistance, allowing for traction by a smaller horsepower agricultural machine. Furthermore, the first to third deep-loosening shovel handles are arranged on the same straight line, with their lengths increasing sequentially, which can progressively increase the deep-loosening depth of the saline-alkali soil layer. This is beneficial for extending the service life of bolts and other connecting parts and reducing downtime for maintenance.

[0037] Specifically, it also includes a short soil-turning plate 8 and a long soil-turning plate 9. The short soil-turning plate 8 is fixedly installed on the side wall of the second deep loosening shovel handle 6, and the long soil-turning plate 9 is fixedly installed on the side wall of the third deep loosening shovel handle 7.

[0038] The short turning plate 8 and the long turning plate 9 are installed in opposite directions, and the size of the long turning plate is larger than that of the short turning plate, so that the short turning plate and the long turning plate can cooperate with each other to disturb and loosen the saline-alkali soil layer between the opposite surfaces of the deep loosening shovel handle in turn.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
