Description

Technical Field

[0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement device for ecological restoration. Background Art

[0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily very high. Alkaline soil refers to soil containing carbonate or heavy phosphate, with a high pH value and alkaline soil. Saline-alkali soil has low organic matter content, low soil fertility, and many anions and cations that are harmful to crops, making it difficult for crops to grow seedlings. Increasing the application of organic fertilizers is an effective measure to improve the soil environment of saline-alkali land. On the one hand, fertilization can neutralize soil alkalinity, and on the other hand, it can accelerate the decomposition of nutrients, thereby promoting the effect of ecological restoration of saline-alkali soil.

[0003] Traditional and common methods of soil fertilization include artificial fertilization and mechanical fertilization. The defects of artificial fertilization and traditional fertilization machinery are that they are time-consuming and labor-intensive, and fertilizers can only be spread on the surface of the soil. Fertilizers are easily lost with precipitation, especially for saline-alkali land, which requires deep and multi-level fertilization to achieve the effect of uniformly improving the soil. Therefore, this application proposes a soil improvement device for ecological restoration that can perform multi-level trench fertilization. Summary of the invention

[0004] 1.

[0018] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] like Figure 1-9 The figure shows an embodiment of the present invention. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a soil improvement device for ecological restoration, comprising a fertilizer spreader consisting of a vehicle body 1 and two wheels 111. The vehicle body 1 comprises a base frame 11, a top frame 12 fixedly arranged at the top of the base frame 11, and two screw rods 13 vertically passing through the base frame 11. An auxiliary wheel 131 is installed at the bottom end of the screw rod 13. After the screw rod 13 is rotated until the auxiliary wheel 131 contacts the ground, the trenching assembly 2 can be separated from the ground, so that the fertilizer spreader can be moved without damaging the long plowshare 22 and the short plowshare 23 when not applying fertilizer. The two wheels 111 are respectively installed at symmetrical two sides of the base frame 11, and a mounting plate 112 is provided at the bottom end of the base frame 11 near the front edge. Further, such as Figure 3 and Figure 4 As shown, a trenching assembly 2 is installed on the mounting plate 112, and the trenching assembly 2 includes a crossbeam 21, a long plowshare 22 and a short plowshare 23. The crossbeam 21 is installed transversely through the mounting plate 112. The number of the long plowshare 22 and the number of the short plowshare 23 are at least two, and each long plowshare 22 and the short plowshare 23 are adjacently arranged, and are used for multi-layer trenching of the soil. When trenching, the auxiliary wheel 131 is adjusted to be away from the ground, and the short plowshare 23 is made to touch the ground. By applying downward pressure to the entire fertilizer spreader, the short plowshare 23 and the long plowshare 22 are made to touch the ground and plow deeply during the movement, thereby realizing the trenching operation; Among them, the long plowshare 22 and the short plowshare 23 are both threadedly connected to the beam 21 with a limiting member 24, and the limiting member 24 is composed of a bolt and a clamping ring at one end of the bolt. When installing the long plowshare 22 and the short plowshare 23, they are respectively sleeved on the beam 21, so that the mounting holes of the long plowshare 22 and the short plowshare 23 correspond to the mounting holes of the beam 21, and then the bolt part of the limiting member 24 is passed through them to complete the fixation.

[0020] Further, such as Figure 2 and Figure 3 As shown, a barrel 121 is provided at the top of the top frame 12, a discharge port 122 is provided at the bottom edge of the barrel 121, a discharge assembly 3 for discharge is provided inside the top frame 12, the discharge assembly 3 includes a first hopper 31 and a second hopper 32, the first hopper 31 is fixedly mounted on the bottom frame 11, and a discharge hopper 313 communicated with the inside of the first hopper 31 is fixedly connected to the bottom end of the first hopper 31, which is used to apply fertilizer to the soil surface; Among them, Figure 3 and Fig. 9 As shown, the second hopper 32 is fixedly connected to the top of the first hopper 31, and an opening connected to the discharge port 122 is provided at the top edge of one side of the second hopper 32. An electrically controlled one-way valve is provided inside the discharge port 122 to facilitate controlling the fertilizer in the barrel 121 to fall at any time; Among them, Figure 3 and Figure 6 As shown, the inner wall of the second hopper 32 is fixedly provided with an inclined plate 311, and the outer surface of one side of the second hopper 32 is provided with a plurality of discharge ports 312, and the discharge ports 312 are located at the lowest position of the inclined surface of the inclined plate 311, so that the fertilizer located on the inclined plate 311 can enter the discharge ports 312, and the outer surface of the second hopper 32 is connected with a plurality of material guide hoses 4 corresponding to each discharge port 312, and the other end of the material guide hose 4 is movably penetrated in the clamping ring of the limiter 24, and is used for fertilizing the soil ditch position, and the inner surface of the lower feed port 122 is provided with fertilizer. After the one-way valve is opened, the fertilizer inside the barrel 121 first falls along the discharge port 122 to one end of the second hopper 32, and then is guided to the entire interior of the spiral rod 321 by the spiral rod 321 and falls. According to the setting of the inclined plate 311, the fertilizer is dispersed and falls to the surface of the inclined plate 311 and the discharge hopper 313 respectively. The fertilizer falling along the discharge hopper 313 is sprinkled on the surface of the soil, and the fertilizer falling along the inclined plate 311 falls into the gully along the discharge port 312 and the guide hose 4, thereby realizing the layered application of the fertilizer.

[0021] Further, such as Figure 8 As shown, a spiral rod 321 is further provided inside the second hopper 32 for guiding the fertilizer into the entire second hopper 32 and causing it to fall, thereby achieving a uniform falling effect. A pulley 322 is provided at one end of the spiral rod 321 and extends through the outside of the top frame 12. When the driving pulley 322 rotates, the spiral rod 321 can be driven to rotate and discharge the fertilizer. Among them, Figure 6 As shown, the side surface of the chassis 11 is also equipped with a first gear 113 and a second gear 114, the central axis of the first gear 113 is fixedly connected to the central axis of the wheel 111, the second gear 114 is meshed with the first gear 113, and the first gear 113 and the pulley 322 are connected and transmitted by a belt. When the wheel 111 moves, the wheel 111 first drives the first gear 113 to rotate, so that the first gear 113 drives the second gear 114 meshed with it to rotate, and the first gear 113 drives the pulley 322 and the spiral rod 321 to rotate through the belt. Therefore, when the fertilizer spreader moves, that is, when the wheel 111 moves, it will drive the spiral rod 321 to rotate and discharge materials, and when the wheel 111 does not move, no materials will be discharged; Among them, a leveling mechanism 115 is arranged on the central axis of the second gear 114. The rotation of the second gear 114 drives the leveling mechanism 115 to rotate synchronously. The leveling mechanism 115 is composed of a central axis and a plurality of rows of extension rods equidistantly arranged outside the central axis. It is used to level the gullies formed after ditching, which not only saves the tedious steps of manual or mechanical leveling, but also can stabilize the fertilizer in the gully, ensuring the multi-layer application effect of the fertilizer.

[0022] When the above embodiment is working, when trenching and fertilizing is performed, the auxiliary wheel 131 is adjusted to be away from the ground by rotating the screw rod 13, and the short plowshare 23 touches the ground. By applying downward pressure to the entire fertilizer spreader, the short plowshare 23 and the long plowshare 22 touch the ground and plow deeply during the movement, thereby realizing the trenching operation. Subsequently, the fertilizer spreader is driven by the locomotive to move forward, and the one-way valve of the discharge port 122 is opened. During the movement of the wheel 111, the first gear 113 is first driven to rotate, so that the first gear 113 drives the second gear 114 meshing with it to rotate. The first gear 113 drives the pulley 322 and the screw rod 321 to rotate through the belt to realize the discharge. The fertilizer inside the barrel 121 first falls along the discharge port 122 to At one end of the second hopper 32, the fertilizer is guided to the entire spiral rod 321 through the spiral rod 321 and falls. According to the setting of the inclined plate 311, the fertilizer is dispersed and falls to the surface of the inclined plate 311 and the discharge hopper 313. The fertilizer falling along the discharge hopper 313 is sprinkled on the surface of the soil, and the fertilizer falling along the inclined plate 311 falls into the gully along the discharge port 312 and the guide hose 4, so that the fertilizer is applied in layers. When the second gear 114 rotates, it also drives the leveling mechanism 115 to rotate synchronously, so as to level the gully formed after ditching. It not only saves the tedious steps of manual or mechanical leveling, but also can stabilize the fertilizer in the gully, so as to ensure the multi-layer application effect of the fertilizer.
