Description

Technical Field

[0001] This utility model belongs to the field of artificial soil laying technology, and in particular relates to a laying device for artificial soil improvement of saline-alkali land. Background Technology

[0002] Artificial soil improvement of saline-alkali land involves artificially formulated composite substrates (blending organic materials such as straw, humus, and biochar with amendments such as zeolite and bentonite) to specifically address the core problems of saline-alkali land, namely "excessive salt, high alkali content, soil compaction, and nutrient deficiency." On the one hand, organic components can increase soil porosity and enhance water and fertilizer retention capacity, while amendments can adsorb excess salt in the soil, regulate pH, and reduce the toxicity of salt and alkali to crop roots. On the other hand, artificial soil can quickly construct a "buffer layer" suitable for crop growth. Combined with drip irrigation for salt drainage, deep tillage, and other supporting measures, it gradually improves soil aggregate structure, transforming barren saline-alkali land into arable farmland, providing an efficient and feasible solution for sustainable agricultural development and ecological restoration in saline-alkali areas.

[0003] Before laying artificial soil in saline-alkali land, the surface usually contains debris such as gravel, dry branches, and clumps of salt. These debris can affect the uniformity of the artificial soil spreading, leading to problems such as local accumulation, hollow areas, or uneven thickness in the laying layer, thereby reducing the improvement effect. Most existing laying equipment only has the function of spreading or compacting, and lacks a structure to actively clean the surface before laying. It usually requires manual pre-treatment, which is not only time-consuming and labor-intensive, but also prone to missing debris, affecting the laying quality. At the same time, for stubborn debris, it is difficult to completely remove it by pushing the structure alone. The equipment is prone to stagnation during the movement, affecting the continuity and stability of the laying operation. Utility Model Content

[0004] This utility model provides a laying device for improving saline-alkali land with artificial soil. It aims to solve the problem that most existing laying equipment only has the function of spreading or compacting, and lacks a structure to actively clean the ground surface before laying. Usually, manual pre-treatment is required, which is not only time-consuming and labor-intensive, but also easy to miss debris, affecting the laying quality.

[0005] This utility model is implemented as follows: a laying device for improving saline-alkali land with artificial soil includes a mobile vehicle, a material storage mechanism installed inside the mobile vehicle, a pressure roller installed on one side of the mobile vehicle, a pretreatment device installed inside the mobile vehicle, and two cleaning devices installed inside the pretreatment device. The pretreatment device includes a connecting rod, a moving vehicle is fixedly connected to the connecting rod, two collars are provided on the outer sleeve of the connecting rod, a linkage rod is fixedly connected to the outer sleeve of the collar, the same push plate is fixedly connected to the outer sleeve of the two linkage rods, two fixing rings are provided on the outer sleeve of the connecting rod, and two coil springs are provided on the outer sleeve of the connecting rod.

[0006] Preferably, one end of the coil spring is fixedly connected to the fixed ring, and the other end of the coil spring is fixedly connected to the collar.

[0007] Preferably, the cross-section of the push plate is configured as a triangle to facilitate the outward diffusion of the obstruction.

[0008] Preferably, the collar and the connecting rod form a rotatable connection.

[0009] Preferably, the cleaning device includes a mounting plate, which is fixedly connected to the inner side of the push plate, and a drive motor is fixedly connected below the mounting plate, with a rotating shaft installed at the output end of the drive motor.

[0010] Preferably, the rotating shaft and the push plate are rotatably connected, and the rotating shaft is fitted with a sleeve plate.

[0011] Preferably, four actuating plates are installed on the outside of the sleeve plate, and the actuating plates overlap with the push plates.

[0012] Compared with related technologies, the artificial soil laying device for improving saline-alkali land provided by this utility model has the following beneficial effects: 1. In this utility model, by setting a coil spring outside the connecting rod, the coil spring continuously applies a restoring force to the collar. The collar drives the linkage rod and the push plate to always maintain an automatic ground-hugging state. When the moving vehicle starts, the push plate moves forward with the moving vehicle. The triangular cross-section of the push plate can spread the debris in front of it to both sides, forming an effective dispersing path. Due to the continuous restoring effect of the coil spring, the push plate can automatically return to its position and maintain ground-hugging operation even when encountering uneven ground. This ensures that the ground is continuously and stably mechanically cleaned before laying, reducing the interference of debris on the integrity and uniformity of the artificial soil laying.

[0013] 2. In this utility model, the drive motor drives the rotating shaft to rotate, and the rotating shaft further drives the sleeve plate to rotate synchronously. When the sleeve plate rotates, the four outer deflecting plates move synchronously. As the device moves forward, the deflecting plates produce a continuous circumferential sweeping effect, which pushes away the debris that the push plate failed to completely disperse, keeping the debris away from the paving path and further expanding the cleaning width. This structure can achieve secondary active dispersion on the basis of the push plate's initial cleaning, making the ground cleaner more thorough. At the same time, it reduces the obstruction of debris on the push plate and the moving vehicle, reduces the resistance to movement, keeps the paving process stable and smooth, and improves the overall work efficiency.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] Example 1 A preferred embodiment of the artificial soil laying device for improving saline-alkali land provided by this utility model is, for example... Figures 1 to 4 As shown: It includes a mobile vehicle 1, a storage mechanism 2 installed inside the mobile vehicle 1, a pressure roller 3 installed on one side of the mobile vehicle 1, a pre-treatment device 4 installed inside the mobile vehicle 1, and two cleaning devices 5 installed inside the pre-treatment device 4. The pretreatment device 4 includes a connecting rod 401, which is fixedly connected to a moving vehicle 1. Two collars 402 are provided on the outer sleeve of the connecting rod 401. A linkage rod 403 is fixedly connected to the outer sleeve of the collars 402. The same push plate 404 is fixedly connected to the outer sleeve of the two linkage rods 403. Two fixing rings 405 are provided on the outer sleeve of the connecting rod 401. Two coil springs 406 are provided on the outer sleeve of the connecting rod 401.

[0019] In this embodiment, a synchronous transmission structure is formed between the push plate 404 and the linkage rod 403. The linkage rod 403 restricts the movement posture of the push plate 404 so that the push plate 404 will not veer or wobble when subjected to force. Through this rigid transmission, the push plate 404 maintains a stable posture when pushing debris forward, thereby improving the uniformity of ground pre-cleaning.

[0020] In a further preferred embodiment of the present invention, one end of the coil spring 406 is fixedly connected to the fixed ring 405, and the other end of the coil spring 406 is fixedly connected to the collar 402. The cross-section of the push plate 404 is set as a triangle to facilitate the outward diffusion of the obstruction. The collar 402 and the connecting rod 401 form a rotatable connection.

[0021] In this embodiment, the coil spring 406 and the collar 402 form an elastic reset engagement. The coil spring 406 continuously applies force to the collar 402, so that the collar 402 can automatically return to its original position after deflection. Through this elastic action, the collar 402 drives the linkage rod 403 and the push plate 404 to always maintain a ground-hugging angle, so that even if the ground is uneven, the push plate 404 can automatically follow the terrain and maintain stable ground-hugging operation.

[0022] Example 2 Based on Example 1, a preferred embodiment of the artificial soil laying device for improving saline-alkali land provided by this utility model is as follows: Figure 4 As shown: The cleaning device 5 includes a mounting plate 501, which is fixedly connected to the inner side of the push plate 404. A drive motor 502 is fixedly connected below the mounting plate 501. A rotating shaft 503 is installed at the output end of the drive motor 502. The rotating shaft 503 and the push plate 404 are rotatably connected. A sleeve plate 504 is provided on the outer side of the rotating shaft 503. Four actuating plates 505 are installed on the outer side of the sleeve plate 504. The actuating plates 505 overlap with the push plate 404.

[0023] In this embodiment, a sleeve plate 504 is fitted over the rotating shaft 503. When the rotating shaft 503 rotates, it drives the sleeve plate 504 to rotate synchronously. Through this structure, the sleeve plate 504, as a rotating carrier, can drive the outer actuating plate 505 to form a wide circumferential sweeping motion, providing a larger coverage area for the cleaning area. The sleeve plate 504 and the actuating plate 505 form a linkage relationship. When the sleeve plate 504 rotates, the actuating plate 505 swings accordingly. During the outward swing, the actuating plate 505 contacts the debris on the ground and quickly pushes it away from the area of ​​the push plate 404, forming a continuous secondary cleaning and keeping the cleaning path unobstructed.

[0024] In summary, by installing a coil spring 406 outside the connecting rod 401, the coil spring 406 continuously applies a restoring force to the collar 402. The collar 402 drives the linkage rod 403 and the push plate 404 to always maintain an automatic ground-contact state. When the moving vehicle 1 starts, the push plate 404 moves forward with the moving vehicle 1. The triangular cross-section of the push plate 404 can spread the debris in front of it to both sides, forming an effective pushing path. Due to the continuous restoring action of the coil spring 406, the push plate 404 can automatically return to its original position and maintain its ground position even when encountering locally uneven ground. The device operates close to the ground, with the drive motor 502 driving the rotating shaft 503 to rotate. The rotating shaft 503 further drives the sleeve plate 504 to rotate synchronously. When the sleeve plate 504 rotates, the four outer actuating plates 505 move synchronously. As the device moves forward, the actuating plates 505 generate a continuous circumferential sweeping effect, pushing the debris that the push plate 404 failed to completely disperse outward again, keeping the debris away from the laying path and further expanding the cleaning width. This structure can achieve secondary active dispersion on the basis of the initial cleaning by the push plate 404, making the ground cleaner more thorough.
