Description

Technical Field

[0001] The utility model provides a biochar spreading device for treating saline-alkali land with straw biochar, belonging to the technical field of equipment for treating saline-alkali land with straw biochar. Background Art

[0002] With the continued impact of global climate change and human activities, the problem of saline-alkali land has become increasingly prominent, becoming a major constraint on sustainable agricultural development. High salt content and alkalinity in saline-alkali soils lead to poor soil structure and low fertility, severely impacting crop growth and yield. Straw biochar is a carbonaceous material produced by high-temperature pyrolysis of crop straw under oxygen-deficient or oxygen-limited conditions. It possesses a rich microporous structure, high aromatization, and high adsorption capacity. It can absorb salt and heavy metal ions from the soil, reducing soil salinity and pollution. Furthermore, its unique physical and chemical properties improve soil structure, enhance soil fertility and water retention, and provide a favorable soil environment for crop growth. Therefore, straw biochar is often used to remediate saline-alkali land.

[0003] When applying straw biochar to saline-alkali land, in order to ensure better integration of biochar and soil, the existing technology often accelerates the integration of biochar and soil by sprinkling water at the same time. For example, the powdered biochar spreading device provided by announcement number CN217657068U humidifies, sprays, and stirs the powdered biochar to mix evenly.

[0004] However, this method is not only troublesome and wastes a lot of water resources, but also increases excessive water accumulation when the soil does not need excess water, which affects plants. In addition, when the wind is too strong, the powdered biochar can easily be blown away, affecting the effectiveness of the biochar application. Utility Model Content

[0005] The technical problem to be solved by the present invention is that the method of using water to accelerate the fusion of biochar and soil is prone to waste water resources and cause excessive water accumulation. At the same time, when the wind is too strong, it will have a great impact on the spreading effect of powdered biochar.

[0006] In order to solve the above problems, the utility model proposes the following technical solutions: a biochar spreading device for treating saline-alkali land with straw biochar, comprising a spreading box, which is fixedly arranged in a vehicle body, and a wheel body is arranged under the vehicle body; a storage tank is provided in the vehicle body, and straw biochar is stored in the storage tank; the bottom of the storage tank is connected to the spreading box, and a spiral feeding structure corresponding to the spreading box is provided in the vehicle body; an outlet is provided at the bottom of the spreading box, and a spreading barrel is fixedly connected to the outlet; a grooving assembly is provided at the bottom of the spreading box, and a fencing structure connected to the bottom of the vehicle body is provided on one side of the grooving assembly; a support block is fixedly connected to one side of the spreading box, and a V-shaped plate is fixedly connected under the support block; the outlet of the spreading box is located in the V-shaped plate, and the V-shaped plate and the fencing structure fit together.

[0007] As an improvement, the spiral feeding structure includes a spiral feeding shaft and a power motor; the spiral feeding shaft is rotatably arranged in the spreading box; a motor slot is opened in the vehicle body, the power motor is located in the motor slot, and the output shaft of the power motor is fixedly connected to the spiral feeding shaft.

[0008] As an improvement, the grooving assembly includes a hydraulic rod and a grooving block. The hydraulic rod is fixedly arranged at the bottom of the spreading box. The grooving block is a conical block and is fixedly connected to the working shaft of the hydraulic rod.

[0009] As an improvement, the enclosure structure includes a vertical plate and a sliding plate; the vertical plate is fixedly arranged under the vehicle body, a sliding groove is opened in the vertical plate, and the sliding plate is slidably arranged in the sliding groove; the sliding plate and the vertical plate are fixedly connected by screws.

[0010] As an improvement, the V-shaped plate is composed of two obliquely symmetrical plates; a groove is opened in the V-shaped plate, and a V-shaped extension plate is slidably arranged in the groove; the extension plate and the V-shaped plate are fixedly connected by screws, and the V-shaped plate and the sliding plate fit together.

[0011] As an improvement, the spreading barrel is located between the V-shaped plate and the vertical plate, and the V-shaped plate is fixedly connected to upper cover plates located on both sides of the spreading box.

[0012] As an improvement, a feed hole connected to the storage tank is opened on the vehicle body, and an end cover is provided on the feed hole.

[0013] Beneficial effects of the utility model:

[0014] A grooving assembly is installed at the bottom of the spreading box. As the vehicle moves, it creates a groove, allowing the powdered straw biochar flowing out of the spreading barrel to enter the groove. Furthermore, a V-shaped plate is fixedly attached to the bottom of the support block. As it moves, the plate re-deposits the soil on both sides of the groove, covering the straw biochar and allowing it to blend better with the soil. Furthermore, the plate and the enclosure form a relatively sealed space, preventing the powdered biochar from being blown away by strong winds during the spreading process, which could affect the spreading effect.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figure 1-4 As shown: The utility model provides a biochar spreading device for treating saline-alkali land with straw biochar: it includes a spreading box 1, which is fixedly arranged in a vehicle body 2, and a wheel body 4 is arranged under the vehicle body 2; a storage tank 13 is opened in the vehicle body 2, and the storage tank 13 stores straw biochar; a feeding hole 3 connected to the storage tank 13 is opened on the vehicle body 2, and an end cover is provided on the feeding hole 3.

[0022] The bottom of the storage tank 13 is connected to the spreading box 1, and a spiral feeding structure corresponding to the spreading box 1 is provided in the vehicle body 2; an outlet is provided at the bottom of the spreading box 1, and a spreading barrel 17 is fixedly connected to the outlet; a grooving assembly is provided at the bottom of the spreading box 1, and a fence structure connected to the bottom of the vehicle body 2 is provided on one side of the grooving assembly; a support block 11 is fixedly connected to one side of the spreading box 1, and a V-shaped plate 8 is fixedly connected under the support block 11; the outlet of the spreading box 1 is located in the V-shaped plate 8, and the V-shaped plate 8 and the fence structure fit together.

[0023] like Figure 4 As shown, the screw feed structure includes a screw feed shaft 16 and a power motor 15. The screw feed shaft 16 is rotatably mounted within the spreading box 1. The vehicle body 2 includes a motor slot 14, in which the power motor 15 is located. The output shaft of the power motor 15 is fixedly connected to the screw feed shaft 16. The screw feed shaft 16 ensures that the material in the storage tank 13 flows evenly from the spreading barrel 17 and is not prone to clogging.

[0024] like Figure 4 As shown, the grooving assembly includes a hydraulic rod 18 and a grooving block 19. The hydraulic rod 18 is fixedly mounted at the bottom of the spreader box 1. The grooving block 19 is a tapered block fixedly connected to the working shaft of the hydraulic rod 18. The hydraulic rod 18 can be used to control the depth of the grooving block 19 inserted into the soil, thereby adjusting the grooving effect. The tip of the tapered grooving block 19 points in the direction of travel of the vehicle body 2. When the vehicle body 2 moves, the tapered block encounters less resistance, making it easier to form a groove.

[0025] like Figure 2 、 4 As shown, the enclosure structure includes a vertical plate 5 and a sliding plate 7; the vertical plate 5 is fixedly arranged under the vehicle body 2, and a sliding groove 6 is provided in the vertical plate 5, and the sliding plate 7 is slidably arranged in the sliding groove 6; the sliding plate 7 is fixedly connected to the vertical plate 5 by screws. The V-shaped plate 8 is composed of two obliquely symmetrical plates; a groove 9 is provided in the V-shaped plate 8, and a V-shaped extension plate 10 is slidably provided in the groove 9; the extension plate 10 is fixedly connected to the V-shaped plate 8 by screws, and the V-shaped plate 8 and the sliding plate 7 fit each other. The spreading barrel 17 is located between the V-shaped plate 8 and the vertical plate 5, and the upper cover plate 12 located on both sides of the spreading box 1 is fixedly connected to the V-shaped plate 8. The V-shaped plate 8, the vertical plate 5, and the upper cover plate 12 can form a relatively sealed structure, thereby avoiding the influence of external wind on the spreading process. The overall lengths of the V-shaped plate 8 and the vertical plate 5 can be adjusted by the extension plate 10 and the sliding plate 7 respectively, so that the vertical plate 5 and the V-shaped plate 8 can be kept away from the ground as a whole when not spreading, making it easier for the vehicle body 2 to move.

[0026] Principle of the utility model

[0027] like Figure 4As shown, before spreading, the vehicle body 2 is located on saline-alkali land, and the hydraulic rod 18 is activated to drive the grooving block 19 into the soil. As the vehicle body 2 moves, the grooving block 19 forms a groove on the soil surface. At the same time, the power motor 15 is activated to drive the screw feed shaft 16 to rotate, and the powdered straw biochar in the storage tank 13 enters the spreading box 1. Under the action of the screw feed shaft 16, it is pushed uniformly and stably toward the position of the spreading cylinder 17, and then falls from the spreading cylinder 17 into the groove dug by the grooving block 19. As the vehicle body 2 moves, the V-shaped block can scrape the two sides of the groove dug by the grooving block 19. Since the V-shaped block has a gathering effect when moving, it can push the soil on both sides of the dug groove into the groove, thereby covering the powdered biochar, and achieving a high degree of biochar and soil fusion without the use of water.

[0028] like Figure 1 、 2 As shown in Figure 3, during the entire spreading process, the V-shaped block, the vertical plate 5, and the upper cover plate 12 can provide a relatively closed environment for the spreading barrel 17, which can greatly isolate the influence of external wind on the spreading process, reduce the risk of powdered straw biochar being blown away by the wind, and improve the spreading effect.

[0029] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
