Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of soil remediation and improvement, and particularly relates to a soil improvement integrated equipment for grassland ecological remediation. BACKGROUND

[0002] In a grassland ecological system, fertile soil can provide plants with nutrients and water required for growth, but due to long-term overgrazing and climate factors, the soil structure of some areas will degrade, the soil fertility will decrease, and the vegetation coverage will decrease, so the soil of the area needs to be improved. However, the existing soil improvement technology has some defects: the traditional manual improvement method mainly performs soil turning operation first, and then simply mixes the soil with added fertilizer with the original soil, but a large amount of soil clumps will appear in the soil turning process, so that the soil inside the soil clumps cannot be mixed with the fertile soil, and the expected improvement effect cannot be achieved. The existing mechanized improvement improves the contact area and mixing efficiency of the original soil and the fertile soil by crushing and screening the original soil, but in actual work, the cutter is easily worn and damaged in the crushing process due to the fact that the deep soil is relatively moist and the stones are wrapped in the moist soil, which increases the maintenance cost and downtime of the equipment, and at the same time, the moist soil clumps and the moist soil attached to the surface of the stones are difficult to effectively separate in the screening process and are prone to block the screen, resulting in low screening efficiency and poor improvement effect.

[0041] (Three) beneficial effects

[0042] Compared with the prior art, the present application has the advantages that:

[0043] I. In the present application, the original soil is dried before being crushed, thereby reducing the water content of the soil and the soil viscosity. The rubber sleeve is raised by the rolling ball and rubs and crushes the dried soil, thereby simulating the rubbing and crushing of the dried soil by hand.

[0044] II. In the present application, since the soil contains stones, part of the soil will adhere to the stones during the drying process of the soil. The rolling ball with the rubber sleeve is in flexible contact with the stones, and rubs and crushes the soil adhered to the stones. The crushed soil falls through the mesh at the bottom of the guide cylinder. The rubber convex on the rubber sleeve is in constant contact with the mesh as the rolling ball rotates, and pushes out the soil particles blocked in the mesh, thereby ensuring that the mesh is always unblocked.

[0045] III. In the present application, the hot air is delivered to each branch pipe through the main air pipe by the external fan, and is blown out in a dispersed form through the air outlet holes at the bottom of the branch pipe. The oscillating shaft drives the oscillating rod to oscillate back and forth, thereby further improving the drying efficiency of the hot air on the soil while the soil is being transported on the flat conveyor belt.

[0046] IV. In the present application, when a stone is stuck between the rolling ball and the guide cylinder, the stone will be pressed by the rolling ball when it moves. At this time, the spring will be deformed and bent, thereby causing the rolling ball with the rubber sleeve to avoid the stone. In the process of avoiding the stone, part of the soil adhered to the stone is also rubbed and crushed, so that it is separated from the stone. When the rolling ball with the rubber sleeve stops contacting the stone, the spring will quickly return to its original shape, thereby driving the rolling ball back to the normal working position.

[0047] V. In the present application, when the rolling ball or the rubber sleeve is damaged, the worker can quickly detach the main shaft flat head clamp seat with threads, and install a new flat head clamp seat with a spring, a rolling ball, a rubber sleeve and a corrugated pipe, thereby reducing the downtime.

[0048] VI. In the present application, during the rubbing process, the stones will roll along the inclined surface of the guide cylinder to the low end of the guide cylinder. The worker can observe the accumulation of stones from the top opening of the guide cylinder. When it is necessary to discharge the stones, the worker only needs to slide the baffle upwards to make the stone discharge port communicate with the outside, thereby discharging the stones.

[0049] VII. In this invention, workers can add new soil mixed with fertilizer into a bidirectional guide cylinder through a feeding pipe, and the old soil will flow into the mixing drum along with the new soil mixed with fertilizer through a discharge pipe for mixing.

[0050] 8. In this invention, the bending plate can divert the soil discharged into the discharge box, avoiding concentrated discharge of soil and causing it to accumulate in a certain area. Attached Figure Description

[0073] In combination with Figure 1 and Figure 5 , the groove wall of the inner groove 1101 is provided with an inner edge 111, the inner edge 111 is fixedly connected with a side baffle 17 through screws, the first driving gear 15 and the first driven gear 16 can be isolated from the outside through the arranged side baffle 17, so as to avoid injuring the workers in the meshing process of the first driving gear 15 and the first driven gear 16, one side of the side baffle 17 is provided with a first driving motor 18, and the output shaft of the first driving motor 18 penetrates the side baffle 17 and is fixedly connected with the first rotating roller 12.

[0074] Specifically, the output shaft of the first driving motor 18 drives the corresponding first rotating roller 12 and first driving gear 15 to rotate clockwise, so that the conveying belt 13 conveys the soil to the horizontal conveying belt 21, the direction adjusting gear 14 engaged with the first driving gear 15 rotates counterclockwise, and the first driven gear 16 engaged with the direction adjusting gear 14 drives the corresponding second rotating roller 2 to rotate clockwise, so as to drive the horizontal conveying belt 21 to convey the soil.

[0075] The upper side of the lateral conveyor is provided with a drying and stirring structure, specifically, as Figures 1-4As shown, the drying and stirring structure comprises a wind cover 4 fixed between the side guard plate 1 and the butt joint guard plate 11, the wind cover 4 is located above the flat conveying belt 21, a plurality of groups of port-shaped shunt pipes 411 are installed on the top of the wind cover 4, the bottom of the plurality of groups of shunt pipes 411 extends into the inner cavity of the wind cover 4, and a plurality of air outlet holes are formed in the bottom of the shunt pipe 411, the plurality of groups of shunt pipes 411 are communicated with the same main air pipe 41, the air inlet of the main air pipe 41 is communicated with the external fan, in the process of conveying the soil by the flat conveying belt 21, the hot air is conveyed into each shunt pipe 411 through the main air pipe 41 by the external fan, and the hot air is blown out in a dispersed form through the air outlet holes in the bottom of the shunt pipe 411, the inner wall of the wind cover 4 is clamped with a mesh plate 42, the shunt pipe 411 is located directly above the mesh plate 42, after the hot air is blown out from the air outlet holes in the bottom of the shunt pipe 411, the mesh plate 42 arranged can avoid that part of the stones or the caked soil in the soil blocks the air outlet holes;

[0076] Further, as shown in Figure 5 and Figure 6 The drying and stirring structure further comprises a plurality of groups of swing shafts 5 slidingly connected between the side guard plate 1 and the butt joint guard plate 11, the bottom of the plurality of groups of swing shafts 5 is fixed with a plurality of swing rods 51, and the swing rods 51 on the adjacent two groups of swing shafts 5 are distributed alternately, and the swing rods 51 are located above the flat conveying belt 21;

[0077] The same end of the plurality of groups of swing shafts 5 extends into the inner groove 1101, and a roller 52 is rotationally connected to the end portion, and the other end extends out of the side guard plate 1 and is threadedly connected with a limiting plate 53, a tension spring 54 is sleeved on the swing shaft 5, and the two ends of the tension spring 54 are fixed with the limiting plate 53 and the side guard plate 1 respectively;

[0078] An axle base 55 is fixed on the side wall of the inner groove 1101, two slide rods 56 are symmetrically fixed on the axle base 55, the same slide cross plate 57 is slidingly connected with the two slide rods 56, the top of the slide cross plate 57 is fixed with a pressing plate 58, one side of the pressing plate 58 is provided with a corrugated pressing portion 59, and the plurality of rollers 52 are in rolling contact with the pressing portion 59;

[0079] The tension spring 54 in the compressed state pulls the swing shaft 5 to shrink along the direction close to the pressing portion 59 through the limiting plate 53, so that the roller 52 always keeps rolling contact with the pressing portion 59;

[0080] A second driven gear 510 is rotationally connected to the side wall of the inner groove 1101, an eccentric shaft 511 is fixed to the side of the second driven gear 510, a connecting rod 512 is slidingly sleeved on the eccentric shaft 511, a butt joint shaft 513 is fixed to one side of the slide cross plate 57 through a connecting lug, and the other end of the connecting rod 512 is slidingly sleeved on the butt joint shaft 513;

[0081] The other second rotating roller 2 fixedly sleeved in the inner groove 1101 is provided with a second driving gear 514 engaged with the second driven gear 510.

[0082] Specifically, when the second rotating roller 2 rotates clockwise, the second driving gear 514 rotates in the same direction, and the second driven gear 510 rotates under the meshing action. The eccentric shaft 511 at the side of the second driven gear 510 drives the sliding horizontal plate 57 to reciprocatingly slide left and right along the slide rod 56 through the connecting rod 512 and the butt shaft 513 during the rotation.

[0083] Meanwhile, the extrusion plate 58 fixedly connected to the sliding horizontal plate 57 also moves in the same direction. At this time, the roller 52 rolls along the extrusion part 59. When the roller 52 rolls from the low position to the high position along the extrusion part 59, the extrusion part 59 extrudes the roller 52 at this time, and the roller 52 drives the corresponding swing shaft 5 to slide away from the extrusion part 59. Meanwhile, the tension spring 54 is in a stretched state. When the roller 52 rolls from the high position to the low position along the extrusion part 59, the tension spring 54 in the stretched state is reset, and the swing shaft 5 is pulled to slide close to the extrusion part 59 through the limiting plate 53.

[0084] The swing shaft 5 drives the swing rod 51 to reciprocatingly swing, so that the soil on the flat conveying belt 21 is reciprocatingly stirred by the swing rod 51 during the conveying of the soil by the flat conveying belt 21, so that the drying efficiency of the hot air on the soil is further improved.

[0085] The grassland ecological restoration soil improvement integrated equipment further comprises a soil improvement box 3 and a flow guide structure installed in the inner cavity of the soil improvement box 3. Figures 7-10 As shown in the figure, the inner cavity top of the soil improvement box 3 is provided with a barrel type rubbing structure, which comprises a guide barrel 31 and a main shaft 32 rotatably connected inside the guide barrel 31. The top of the guide barrel 31 is open and located below the output end of the horizontal conveyor. A plurality of mesh holes 3101 are formed in the bottom of the guide barrel 31. A plurality of springs 34 are installed on the main shaft 32. The free end of the spring 34 is fixedly connected to a rolling ball 35. The rolling ball 35 leaves a gap with the inner wall of the guide barrel 31.

[0086] Further, a plurality of flat head clamping seats 33 are threadedly connected to the main shaft 32. One end of the spring 34 is fixedly connected to the flat head clamping seat 33. A partition ring 36 is fixedly sleeved on the rolling ball 35. The same bellows 37 is fixedly connected between the flat head clamping seat 33 and the partition ring 36. The bellows 37 is sleeved on the spring 34. A rubber sleeve 38 is fixedly sleeved on the rolling ball 35. A plurality of rubber protrusions 381 are arranged on the rubber sleeve 38. The rubber protrusions 381 are in contact with the inner wall of the guide barrel 31.

[0087] Further, the guide cylinder 31 is arranged in an inclined manner;

[0088] The second driving motor 6 is arranged on one side of the soil improvement box 3, and the output shaft of the second driving motor 6 is fixed to the main shaft 32 through the soil improvement box 3 and the guide cylinder 31. The flat conveying belt 21 conveys the dried soil into the guide cylinder 31 and drops to the bottom of the guide cylinder 31. The main shaft 32 is driven to rotate by the output shaft of the second driving motor 6. When the main shaft 32 rotates, the spring 34 is driven to rotate in the same direction by the flat head clamp seat 33. The rolling ball 35 arranged can lift the rubber sleeve 38 and drive the rubber sleeve 38 to rub and crush the dried soil, so as to simulate the effect of rubbing and crushing the dried soil by hand.

[0089] Since the soil contains stones, part of the soil will adhere to the stones during the drying process of the soil. The rolling ball 35 sleeved with the rubber sleeve 38 will be in flexible contact with the stones, and at the same time, the soil adhering to the stones will be rubbed off. The crushed soil will fall through the mesh 3101 at the bottom of the guide cylinder 31. The rubber convex 381 arranged on the rubber sleeve 38 will be in contact with the mesh 3101 during the rotation of the rolling ball 35, so as to push the soil particles blocked in the mesh 3101 out, so as to ensure that the mesh 3101 is always in an unblocked state.

[0090] When the stone is stuck between the rolling ball 35 and the guide cylinder 31, the stone will press the rolling ball 35 when the rolling ball 35 moves. At this time, the spring 34 will be deformed and bent, so that the rolling ball 35 sleeved with the rubber sleeve 38 avoids the stone. At the same time, part of the soil adhering to the stone will be rubbed and separated from the stone during the avoiding process. When the rolling ball 35 sleeved with the rubber sleeve 38 stops contacting the stone, the spring 34 will quickly return to the original shape, and then drive the rolling ball 35 to return to the normal working position.

[0091] As the stone is continuously rubbed, since the guide cylinder 31 is arranged in an inclined manner, the stone will roll along the inclined surface of the guide cylinder 31 and be rubbed by other rolling balls 35 sleeved with rubber sleeves 38, so as to improve the separation effect of the soil adhering to the stone, and avoid local accumulation of the stone.

[0092] The corrugated pipe 37 arranged can avoid the stone being stuck in the spring 34 and affecting the bending of the spring 34.

[0093] When the rolling ball 35 or the rubber sleeve 38 is damaged, the worker can quickly disassemble the flat head clamp seat 33 screwed on the main shaft 32, and install a new flat head clamp seat 33 with the spring 34, the rolling ball 35, the rubber sleeve 38 and the corrugated pipe 37.

[0094] The low end of the guide cylinder 31 extends out of the soil improvement box 3, and the end is provided with a stone discharge port 3102. One side of the guide cylinder 31 is provided with a socket, and a baffle 39 is slidably connected in the socket. The bottom of the baffle 39 is in contact with the soil improvement box 3. The baffle 39 is used to block the stone discharge port 3102. During kneading, the stones will roll along the inclined surface of the guide cylinder 31 to the low end of the guide cylinder 31. The staff can observe the accumulation of stones from the top opening of the guide cylinder 31. When it is necessary to discharge the stones, the baffle 39 is only slid upward to make the stone discharge port 3102 communicate with the outside, and then the stones are discharged.

[0095] The flow guide structure is installed at the bottom of the guide cylinder 31. The plurality of mesh holes 3101 are in communication with the flow guide structure. The bottom of the flow guide structure is provided with two discharge pipes 310. The inner cavity bottom of the soil improvement box 3 is rotatably connected with a rotary mixing structure, and the rotary mixing structure is located below the flow guide structure. The rotary mixing structure includes a mixing roller 8. As shown in Figure 12 The inner cavity bottom of the soil improvement box 3 is symmetrically fixed with two supports 311. The two supports 311 are rotatably connected with the same mixing roller 8. The mixing roller 8 can be supported by the supports 311. The two sides of the mixing roller 8 are open. The discharge ports of the two discharge pipes 310 respectively extend from the openings on both sides of the mixing roller 8 to the inside of the mixing roller 8.

[0096] Specifically, as shown in Figures 10-13 The flow guide structure includes a bidirectional flow guide cylinder 7. The top of the bidirectional flow guide cylinder 7 is open, and the top is fixed to the bottom of the guide cylinder 31. The inner wall of the bidirectional flow guide cylinder 7 is fixed with a flow guide plate 71 in the shape of an inverted V. The plurality of mesh holes 3101 are in communication with the inner cavity of the bidirectional flow guide cylinder 7.

[0097] The inlet ports of the two discharge pipes 310 are respectively communicated at the bottom of the bidirectional flow guide cylinder 7. The two sides of the flow guide plate 71 are respectively communicated with the corresponding discharge pipes 310.

[0098] One side of the bidirectional flow guide cylinder 7 is communicated with two feeding pipes 72. The discharge ports of the two feeding pipes 72 are respectively located above the inlet ports of the discharge pipes 310.

[0099] Specifically, the crushed soil passes through the mesh holes 3101 at the bottom of the guide cylinder 31 on the flow guide plate 71, and flows to the corresponding discharge pipe 310 along the two ends of the flow guide plate 71. At the same time, the staff can add the new soil mixed with fertilizer into the bidirectional flow guide cylinder 7 through the feeding pipe 72. The old soil will flow into the mixing roller 8 through the discharge pipe 310 together with the new soil mixed with fertilizer for mixing.

[0100] Among them, the staff can also install a vibration pump at the bottom of the flow guide plate 71 to improve the flow speed of the soil on the flow guide plate 71.

[0101] Further, as shown in Figure 13 The interior of the mixing drum 8 is centrally symmetrical and has two horn-shaped guide cavities 801. The two guide cavities 801 are connected and communicate with each other, and the sides away from each other of the two guide cavities 801 communicate with the outside through the mixing drum 8. The discharge ports of the discharge pipes 310 extend into the guide cavities 801 on the same side. The new and old soil is transported into the two guide cavities 801 through the two discharge pipes 310. The mixing drum 8 is fixedly sleeved with a third driven gear 82. The inner cavity bottom of the soil improvement box 3 is fixedly connected with a third driving motor 83. The output shaft of the third driving motor 83 is fixedly sleeved with a third driving gear 84 engaged with the third driven gear 82. The output shaft of the third driving motor 83 drives the third driving gear 84 to rotate, which drives the third driven gear 82 to rotate, so that the mixing drum 8 rotates. The wall of the discharge pipe 310 and the inner wall of the guide cavity 801 leave a gap, so as to avoid interference between the mixing drum 8 and the discharge pipe 310 during rotation.

[0102] The inner walls of the two guide cavities 801 are fixedly connected with spiral guide inner edges 81, which are centrally symmetrically distributed.

[0103] The mixing drum 8 is equally spaced and has a plurality of discharge ports between the two spiral guide inner edges 81. Each group of discharge ports includes a circumferentially arranged slot 802 on the mixing drum 8. The slots 802 on adjacent groups of discharge ports are staggered. After the new and old soil is transported into the two guide cavities 801, it will fall to the bottom of the guide cavities 801. With the rotation of the mixing drum 8, the new and old soil on both sides of the mixing drum 8 will roll and mix along the spiral path of the spiral guide inner edge 81 and the slope at the bottom of the guide cavity 801, so that the new and old soil on both sides of the mixing drum 8 is mixed, and the mixed soil is discharged from the plurality of slots 802 along the slope of the guide cavity 801, thereby obtaining improved soil with less stone content and improved fertility.

[0104] The bottom of the soil improvement box 3 is provided with a shunt structure, and the discharge port of the mixing drum 8 is provided with a discharge box 9. Specifically, the discharge box 9 is fixedly connected to the bottom of the mixing drum 8. The top and bottom of the discharge box 9 are open, and the top opening of the discharge box 9 is located directly below the plurality of discharge ports. The mixed soil is discharged into the discharge box 9 along the slot 802. The inner wall of the discharge box 9 is fixedly connected with a plurality of bent plates 91. The inner cavity of the discharge box 9 is divided into a plurality of discharge channels by the bent plates 91. The soil discharged into the discharge box 9 is discharged in a shunt form by the bent plates 91, avoiding the soil being concentrated and accumulated in a certain area.

[0105] To sum up, the workflow of the present application is as follows:

[0106] The old soil to be improved is placed on the conveying belt 13, the first driving motor 18 drives the corresponding first rotating roller 12 and the first driving gear 15 to rotate clockwise, so that the conveying belt 13 conveys the soil to the flat conveying belt 21, the direction-changing gear 14 engaged with the first driving gear 15 rotates counterclockwise, and the first driven gear 16 engaged with the direction-changing gear 14 drives the corresponding second rotating roller 2 to rotate clockwise, so that the flat conveying belt 21 conveys the soil and performs drying treatment;

[0107] During the conveying of the soil by the flat conveying belt 21, the hot air is conveyed by the external fan through the main air pipe 41 to each branch pipe 411, and is blown out in a dispersed manner through the air outlet holes at the bottom of the branch pipe 411, so as to dry the soil, wherein, when the second rotating roller 2 rotates clockwise, the second driving gear 514 rotates in the same direction, and drives the second driven gear 510 to rotate under the meshing action, the eccentric shaft 511 at the side of the second driven gear 510 drives the sliding cross plate 57 to slide left and right along the sliding rod 56 through the connecting rod 512 and the butt shaft 513 during the rotation;

[0108] Meanwhile, the extrusion plate 58 fixed on the sliding cross plate 57 also moves in the same direction, at this time, the roller 52 rolls along the extrusion part 59, when the roller 52 rolls from the low position to the high position of the extrusion part 59, the extrusion part 59 extrudes the roller 52 at this time, the roller 52 drives the corresponding swing shaft 5 to slide away from the extrusion part 59, and the tension spring 54 is in a stretched state, when the roller 52 rolls from the high position to the low position of the extrusion part 59, the tension spring 54 in the stretched state is reset, and the swing shaft 5 is pulled to slide close to the extrusion part 59 through the limiting plate 53;

[0109] The swing shaft 5 drives the swing rod 51 to swing reciprocally, so that the soil on the flat conveying belt 21 is reciprocally stirred by the swing rod 51 during the conveying of the soil by the flat conveying belt 21, while being dried by the hot air, so as to further improve the drying efficiency of the soil by the hot air.

[0110] The dried soil is sent to the guide cylinder 31 with the flat conveying belt 21 and falls at the bottom of the guide cylinder 31, the output shaft of the second driving motor 6 drives the main shaft 32 to rotate, the main shaft 32 drives the spring 34 to rotate in the same direction through the flat head clamp seat 33 during the rotation, the rolling ball 35 arranged can lift the rubber sleeve 38, and drive the rubber sleeve 38 to rub and crush the dried soil, so as to simulate the effect of rubbing and crushing the dried soil by hand.

[0111] Due to the fact that the soil contains stones, during the drying process of the soil, part of the soil will be attached to the stones, when the rolling ball 35 provided with the rubber sleeve 38 contacts the stones, the soil attached to the stones will be kneaded off, and the crushed soil will fall through the mesh 3101 at the bottom of the guide cylinder 31; the rubber convex 381 provided on the rubber sleeve 38 will be in contact with the mesh 3101 constantly with the rotation of the rolling ball 35, which can push the soil particles blocked in the mesh 3101 out, ensuring that the mesh 3101 is always in an unblocked state;

[0112] When the stones are stuck between the rolling ball 35 and the guide cylinder 31, the stones will extrude the rolling ball 35 when the rolling ball 35 moves, at this time, the spring 34 will be deformed and bent, so that the rolling ball 35 provided with the rubber sleeve 38 avoids the stones, and at the same time, part of the soil attached to the stones will be kneaded and separated from the stones during the avoiding process, when the rolling ball 35 provided with the rubber sleeve 38 stops contacting the stones, at this time, the spring 34 will quickly restore to the original shape, and then drive the rolling ball 35 back to the normal working position;

[0113] With the stones being continuously kneaded, since the guide cylinder 31 is arranged in an inclined manner, the stones will roll along the inclined surface of the guide cylinder 31, and be kneaded by other rolling balls 35 provided with rubber sleeves 38, so as to improve the separation effect of the soil attached to the stones, and avoid local accumulation of the stones, during the kneading process, the stones will roll along the inclined surface of the guide cylinder 31 to the low end of the guide cylinder 31, and the staff can observe the accumulation amount of the stones from the top opening of the guide cylinder 31, when it is necessary to discharge the stones, the staff only needs to slide the baffle 39 upwards, so that the stone discharge port 3102 is connected to the outside, and then the stones are discharged;

[0114] The crushed soil passes through the mesh 3101 at the bottom of the guide cylinder 31 on the guide plate 71, and flows along both ends of the guide plate 71 to the corresponding discharge pipe 310, and at the same time, the staff can add the new soil mixed with the fertilizer into the bidirectional guide cylinder 7 through the feeding pipe 72, and the old soil will flow into the mixing drum 8 together with the new soil mixed with the fertilizer through the discharge pipe 310;

[0115] After the new and old soil is transported into the two guide inner cavities 801, it will fall to the bottom of the guide inner cavities 801, and as the mixing roller 8 rotates, the new and old soil on both sides of the mixing roller 8 will roll and mix along the spiral path of the spiral guide inner along 81 and along the slope at the bottom of the guide inner cavity 801, so that the new and old soil on both sides of the mixing roller 8 is mixed, and the mixed soil is discharged from the multiple slots 802 to the discharge box 9 along the slope of the guide inner cavity 801, and under the action of the bent plate 91, the soil discharged into the discharge box 9 is discharged in a shunt form, avoiding the concentration of soil, which leads to accumulation in a certain area.
