Description

Technical Field

[0001] The invention relates to the technical field of farmland restoration, in particular to a farmland restoration device for improving soil structure in coastal areas. Background Art

[0002] Coastal areas are close to the ocean, and under the action of tides, seawater often floods or infiltrates the surrounding land. Seawater contains a large amount of salt, which enters the soil with the infiltration of seawater, and long-term accumulation leads to soil salinization; at the same time, the groundwater level in coastal areas is often high, and the groundwater usually has a high salt content. When the groundwater level rises, the salt in the water will also rise to the surface. Through evaporation, the water will be lost, and the salt will remain on the surface of the soil, resulting in a decrease in soil organic matter content, the destruction of soil structure and compaction, and a decrease in fertility, which will have an adverse effect on the growth and development of crops, resulting in a decrease in crop yield and quality. In order to ensure the sustainable development of agriculture in coastal areas, effective measures must be taken to repair damaged soil and improve soil quality, but the existing repair devices still have certain shortcomings when used.

[0003] For example, a soil remediation device for damaged cultivated land with publication number CN219851350U rotates the first crushing shaft, the second crushing shaft and the third crushing shaft so that the soil entering the crushing bin can be fully crushed, and the agglomerated soil can also be fully broken up. The repair liquid sprayed from the liquid filling tank arranged on the crushing bin can also be sprayed on the soil being crushed, so as to improve the mixing of the repair liquid and the soil and improve the degree of soil remediation. However, the crushing effect of different soil types may vary. If the hard or sticky soil is not screened out before crushing, the ideal crushing effect may not be achieved, and the presence of impurities in the soil will affect the uniform crushing of the soil, resulting in uneven size of the crushed soil particles, affecting the subsequent repair effect. At the same time, the soil containing the repair liquid is directly discharged to the ground, and the effective ingredients in the repair liquid are easily lost due to evaporation, which not only reduces the use efficiency of the repair liquid, but also may affect the repair effect of the deep soil due to incomplete penetration of the repair liquid.

[0004] Therefore, we proposed a farmland restoration device for improving soil structure in coastal areas in order to solve the above-mentioned problems. Summary of the invention

[0020] 1. A screening roller is provided.

The device body 1 will drive the shoveling device 4 to move forward, so that the shoveling device 4 is used to dig the soil, and then the excavated soil will enter the conveying device 3. The conveying device 3 is responsible for transporting the soil from the shoveling device 4 to the top of the feeding pipe 2 on the device body 1, so that the soil enters the device body 1 from the feeding pipe 2 for processing, and then the processed soil is discharged.

[0038] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above embodiment 1. Since the crushing effects of different soil types may be different, if the hard or heavy soil is not screened out before crushing, the ideal crushing effect may not be achieved, and the presence of impurities in the soil will affect the uniform crushing of the soil, resulting in uneven soil particle size after crushing, affecting the subsequent repair effect.

There are a crushing chamber 101 and a guide chamber 102, the guide plate 8 is inclined, and the guide plate 8 is located below the impurity discharge hole 201, and the end of the guide plate 8 away from the impurity discharge hole 201 is aligned with the upper opening of the collecting frame 6, and a slot is provided on the device body 1 between the guide plate 8 and the collecting frame 6. The screening mechanism 7 also includes an extrusion block 702, a filter plate 703, a crushing assembly 704 and a brush 705. The extrusion block 702 is fixedly sleeved on the shaft end of the screening roller 701, and the bottom end of the extrusion block 702 is provided with an inclined surface, and Two extrusion blocks 702 are symmetrically arranged about the screening roller 701, and a filter plate 703 is arranged below the two extrusion blocks 702, and the filter plate 703 is slidably connected to the inner wall of the device body 1, and a brush 705 is fixedly connected to the bottom of the filter plate 703, and the crushing component 704 is located at the lower end of the brush 705, and the crushing component 704 is rotatably arranged in the crushing chamber 101, and filter holes are opened on the filter plate 703, and the diameter of the filter hole located above the guide chamber 102 is smaller than the diameter of the filter hole above the crushing chamber 101, The upper end surface of the filter plate 703 is integrally connected with a raised inclined surface, and the raised inclined surface corresponds to the extrusion block 702. The bottom end of the filter plate 703 is fixedly connected with an elastic connection frame 17, and the bottom end of the elastic connection frame 17 is fixedly connected to the inner wall of the device body 1. The crushing assembly 704 includes a crushing roller 7041, which is rotatably arranged in the crushing chamber 101, and two crushing rollers 7041 are symmetrically arranged about the crushing chamber 101, and the axial ends of the two crushing rollers 7041 both penetrate and extend out of the device body 1.

[0039] In this technical solution, Figure 1 As shown, by using the setting of the screening roller 701 and the filter plate 703, the screening roller 701 can separate the stones in the soil when rotating to prevent them from falling directly onto the filter plate 703, thereby damaging the filter plate 703 and improving the soil quality. The filter holes on the filter plate 703 are of different sizes, so that the soil can be screened and large pieces of soil can be crushed to improve the effect of the subsequent mixed repair liquid.

[0040] Its use is as Figure 2-Figure 7The technical solution shown in the figure, first turn on the double-axis motor 12, the double-axis motor 12 will drive the rotating roller 1302 to rotate, thereby driving the belt 16 to rotate through the rotating roller 1302, and the belt 16 will drive the screening roller 701 to rotate, and the falling soil will be screened, and the hard agglomerated soil and impurities will be separated and discharged from the impurity discharge hole 201 on the side of the feed pipe 2 to the guide plate 8. Since the guide plate 8 is inclined, the hard agglomerated soil and impurities will roll along the guide plate 8 to the collection frame 6 for collection, and pass through the screening The soil on the roller 701 will fall onto the filter plate 703, and then the screening roller 701 will drive the extrusion block 702 to rotate when rotating, so that the bottom end of the extrusion block 702 intermittently fits the inclined surface of the filter plate 703, thereby pushing the filter plate 703 to move up and down to screen the soil.

[0041] When the filter plate 703 vibrates up and down, it will drive the brush 705 and the baffle 1301 to move up and down at the same time. The brush 705 will intermittently fit the surface of the two crushing rollers 7041, so as to clean the crushing rollers 7041 and improve the crushing effect of the crushing rollers 7041. The baffle 1301 moves up and down, and will intermittently open the openings connecting the crushing chamber 101 and the material guide chamber 102 with the box body 9, so that the soil can intermittently fall into the box body 9 and slide along the inclined surface in the box body 9 into the first discharge pipe 10 and the second discharge pipe 11.

[0042] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiment 1 and embodiment 2. When the soil containing the repair liquid is directly discharged onto the ground, the effective components in the repair liquid are easily lost due to evaporation, which not only reduces the use efficiency of the repair liquid, but also may affect the repair effect of the deep soil layer due to the incomplete penetration of the repair liquid. In order to further solve this technical problem, the technical solution of this invention is as follows: Figure 8-Figure 11As shown, a material discharge component of a repair device is disclosed, wherein a box body 9 is fixedly connected inside a device body 1 between a crushing chamber 101 and a guide chamber 102, and a first material discharge pipe 10 is fixedly connected to an outer wall of the box body 9, and an end of the box body 9 away from the first material discharge pipe 10 is fixedly connected to a second material discharge pipe 11, a double-axis motor 12 is fixedly connected inside the box body 9, and two axial ends of the double-axis motor 12 respectively penetrate into the first material discharge pipe 10 and the second material discharge pipe 11 and are fixedly connected to a material discharge mechanism 13, and one end of the material discharge mechanism 13 extends out, the box body 9 is connected with the crushing chamber 101 and the guide chamber 102, and an inclined surface is arranged inside the box body 9, a discharge port 901 is opened at the bottom of the box body 9, and two discharge ports 901 are arranged at equal distances above and below, and the discharge port 901 located at the top The outlet 901 is connected to the first feeding tube 10, and the outlet 901 located below is connected to the second feeding tube 11. The feeding mechanism 13 includes a baffle 1301 and a rotating roller 1302. The baffle 1301 is slidably arranged in the side wall of the box body 9, and an opening is opened on the baffle 1301. Two baffles 1301 are symmetrically arranged about the box body 9, and the tops of the two baffles 1301 are fixedly connected to the bottom end of the filter plate 703. The rotating roller 1302 is connected to the shaft end of the dual-axis motor 12, and the inner wall of the rotating roller 1302 located in the second feeding tube 11 is fixedly connected with the nozzle 14, and the shaft end of the rotating roller 1302 located in the second feeding tube 11 is connected with a rotating joint, and the rotating joint is connected to the liquid feeding box 5 through a pipeline. The shaft end of the rotating roller 1302 inside extends through the device body 1, and a belt 16 is sleeved on the outer side of the extended end of the rotating roller 1302. The unloading mechanism 13 also includes a pulley 1303, a fixed plate 1304, a protruding block 1305, a moving member 1306, a connecting bracket 1307, a first rotating plate 1308 and a second rotating plate 1309. The pulley 1303 is rotatably arranged on the outer side of the device body 1, and the outer wall of the pulley 1303 is fixedly connected to the fixed plate 1304, and the end away from the pulley 1303 is fixedly connected to the protruding block 1305, a sliding groove 15 is opened on the moving member 1306, and the protruding block 1305 is slidably arranged in the sliding groove 15, and the bottom end of the moving member 1306 is fixedly connected to the connecting bracket 1307, and the bottom end of the connecting bracket 1307 is rotatable. A first rotating plate 1308 is connected, and a second rotating plate 1309 is rotatably connected to a connecting bracket 1307 below the first rotating plate 1308. The first rotating plate 1308 and the second rotating plate 1309 are rotatably connected to the outer wall of the box body 9 at one end away from the connecting bracket 1307, and the first rotating plate 1308 and the second rotating plate 1309 are arranged one by one below the discharge port 901, and the length of the first rotating plate 1308 is greater than that of the second rotating plate 1309. The same side shaft ends of the screening roller 701, the crushing roller 7041, the pulley 1303 and the rotating roller 1302 all extend through the device body 1, and the protruding ends of the screening roller 701, the crushing roller 7041, the pulley 1303 and the rotating roller 1302 are connected by a belt 16.

[0043] In this technical solution, Figure 8 As shown, by utilizing the setting of the first discharge pipe 10 and the second discharge pipe 11, the pulley 1303 drives the fixed plate 1304 to rotate synchronously when rotating, and the raised block 1305 on the fixed plate 1304 is slidably connected with the slide groove 15, thereby driving the moving part 1306 to reciprocate up and down, and then the moving part 1306 will pull the first rotating plate 1308 and the second rotating plate 1309 to shake at the same time through the connecting bracket 1307. Since the first rotating plate 1308 and the second rotating plate 1309 are of different lengths, the soil is spread on the ground one after another, and the covering soil layer can effectively reduce the evaporation of the mixed liquid in the soil, ensuring that the effective ingredients in the repair liquid can fully penetrate into the soil, fully contact and act with harmful substances in the soil, and improve the utilization rate of the repair liquid.

[0044] Its use is as Figure 9-11 According to the technical solution shown, first, the dual-axis motor 12 will drive the two rotating rollers 1302 to rotate simultaneously when rotating, so that the two rotating rollers 1302 will further break up the soil at the same time, and then the soil will slide down from the gap between the rotating rollers 1302. Since the inner wall of the rotating roller 1302 in the second feeding pipe 11 is fixedly connected with the nozzle 14, the pump in the liquid supply box 5 is turned on at this time, so that the pump conveys the repair liquid in the liquid supply box 5 to the nozzle 14 through the pipeline, and then the nozzle 14 sprays it into the falling soil, so that the repair liquid is evenly sprayed into the soil, and then the soil mixed with the repair liquid will slide down to the second rotating plate 1309 through the inclined surface at the bottom end of the second feeding pipe 11, and the soil not sprayed with the mixed liquid will slide down to the first rotating plate 1308 through the first feeding pipe 10;

[0045] The belt 16 drives the pulley 1303 to rotate synchronously. When the pulley 1303 rotates, it drives the fixed plate 1304 to rotate, and then the fixed plate 1304 drives the raised block 1305 to rotate. The raised block 1305 slides along the slide groove 15, thereby driving the moving member 1306 to reciprocate up and down. When the moving member 1306 moves, it pulls the connecting bracket 1307 to move up and down along the inner wall of the device body 1, thereby pulling the first rotating plate 1308 and the second rotating plate 1309 to rotate up and down through the connecting bracket 1307, and the soil is evenly scattered on the ground. Since the first rotating plate 1308 is higher than the second rotating plate 1309, and the first rotating plate 1308 is longer than the second rotating plate 1309, the soil mixed with the mixed liquid will fall first, and the soil without the mixed liquid will fall later, thereby covering the soil mixed with the mixed liquid.
