Description

Technical Field

[0001] The present invention belongs to the technical field of dredging equipment, and specifically relates to a solid-liquid separation device for dredging water channels. Background Art

[0002] To solve the problem of farmland irrigation, a large number of irrigation water channels have been built in rural areas of our country. By diverting water, sufficient water is provided for farmland to meet the growth needs of crops. The water channel system is usually divided into multiple levels such as main canals, branch canals, distributary canals, field canals, and capillary canals, and the water source is transported to the field plots step by step to ensure that the farmland can also obtain necessary irrigation during drought periods. At the same time, when there is heavy rain or the groundwater level is too high, the water channels can drain the field water in time to prevent waterlogging disasters. The layout of the drainage ditches is opposite to that of the irrigation canals. The water is gradually collected from the small capillary canals in the field to larger drainage ditches and finally discharged into natural water bodies to effectively manage the water in the farmland.

[0003] A patent application with the publication number CN115680053B discloses an agricultural water channel dredging device. Through the reciprocating swing of the swing push plate, the silt is pushed into the silt conduit. Not only can the silt be smoothly discharged from the water channel, but also because there is a large space at the mouth of the silt conduit and the one-way valve plate, the stones can also be smoothly discharged. And when encountering stones, the elastic scraper can push the stones away to avoid equipment failures caused by stones getting stuck between the swing push plate and the silt conduit, effectively improving the reliability of the dredging device.

[0004] In the above-mentioned prior art, when dredging the water channel, after the silt is cleared from the water channel, the silt can be discharged into the field and dried for use as waste. Since the water channel is used for a long time and is located outdoors, plastic bags may fall into the water channel and mix with the silt. Since the plastic bags are non-degradable materials, after discharging the silt with plastic bags into the field, it will hinder the growth of crops, not degrade for a long time, affect the absorption of nutrients and water by crops, and lead to a reduction in production. Therefore, the present invention provides a solid-liquid separation device for dredging water channels. Summary of the Invention

Specific Embodiment

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Embodiment 1: As Figures 1-4As shown in the figure, a solid-liquid separation device for dredging irrigation canals according to an embodiment of the present invention includes two side plates 1. At the lower end between the two side plates 1, an inclined plate 11 is fixedly connected. At one end of the two side plates 1 away from the inclined plate 11, a first rectangular plate 13 is fixedly connected. A dredging component is arranged between the inclined plate 11 and the first rectangular plate 13. The dredging component includes arc-shaped blocks 2 respectively arranged on one side of the two opposite side plates 1. A spiral blade 21 is rotatably arranged inside the arc-shaped block 2. Third cylindrical bars 23 are respectively rotatably arranged on one side of the two opposite arc-shaped blocks 2. A plurality of paddles 231 are fixedly connected to the outer side of the third cylindrical bar 23. Rectangular cylinders 22 are respectively fixedly connected to the upper ends of the arc-shaped blocks 2. The rectangular cylinders 22 penetrate through the side plates 1. Impurity removal components are respectively arranged inside the rectangular cylinders 22. The impurity removal components include second cylindrical bars 222 rotatably arranged inside the rectangular cylinders 22. A plurality of arc-shaped blades 223 are fixedly connected to the outer side of the second cylindrical bar 222.

[0023] Specifically, the irrigation canal provides sufficient water for the farmland through water diversion to meet the growth needs of crops. After long-term use, silt will be generated at the bottom of the canal. Excessive silt will affect the water flow rate. Dredging can remove sediments such as silt, weeds, and garbage in the canal, restore the designed cross-section of the canal, and ensure unobstructed water flow. By placing the side plates 1 into the canal, the side plates 1 are located on both sides inside the canal, and the inclined plate 11 is located at the bottom inside the canal. Subsequently, the side plates 1 are driven to slide in the canal. At the same time, the third cylindrical bars 23 on both sides are driven to rotate, driving the paddles 231 to rotate to stir the silt in the middle to the arc-shaped blocks 2 on both sides. At the same time, the spiral blade 21 is driven to rotate, driving the silt inside the arc-shaped block 2 to be conveyed upward until it is conveyed into the rectangular cylinder 22. Subsequently, the second cylindrical bar 222 is driven to drive a plurality of arc-shaped blades 223 to rotate, so that the plurality of arc-shaped blades 223 rotate in the silt, and the plastic bags in the silt can be hooked out. The silt after the plastic bags are hooked out is then discharged from the rectangular cylinder 22 and discharged on both sides of the canal. After drying and crushing, it can be used as fertilizer for the fields. By driving the spiral blade 21 to rotate to drive the silt to be conveyed into the rectangular cylinder 22, and then driving the second cylindrical bar 222 to rotate to drive the arc-shaped blades 223 to rotate in the silt in the rectangular cylinder 22, the plastic bags in the silt are hooked out, and then discharged into the fields. Preventing the plastic bags from being mixed with the silt and discharged into the fields will hinder the growth of crops, not degrade for a long time, affect the crops' absorption of nutrients and water, and thus lead to the problem of reduced production. As Figure 7 As shown in the figure, a U-shaped pointed block 12 is fixedly connected to one side of the side plate 1 and the inclined plate 11.

[0024] Specifically, when the side plate 1 is driven to slide in the canal, the U-shaped pointed block 12 is driven to stick to the bottom and both sides of the canal. The U-shaped pointed block 12 can scrape the silt at the inner bottom and both sides of the canal, making the cleaning more thorough.

[0025] As Figure 4As shown, rectangular holes 221 are respectively provided at the upper ends of the rectangular cylinders 22, round holes are respectively provided at the lower ends of the rectangular cylinders 22, filter plates 224 are respectively arranged in the round holes, the lower ends of the filter plates 224 are fixedly connected to the side plates 1 through connecting pipes 225, and the connecting pipes 225 penetrate through the side plates 1.

[0026] Specifically, driving the rotation of the spiral blade 21 drives the silt to be conveyed into the rectangular cylinder 22. Subsequently, driving the rotation of the arc blade 223 hooks out the plastic bags in the silt, so that the plastic bags are discharged from the rectangular holes 221. At this time, the silt in the rectangular cylinder 22 still contains a certain amount of moisture. The filter plate 224 filters the moisture in the silt, and the filtered silt is then discharged from the rectangular cylinder 22. When the arc blade 223 rotates, it can scrape the filter plate 224 to prevent the filter plate 224 from being blocked. The filtered moisture is then discharged into the water channel through the connecting pipe 225.

[0027] As Figure 6 shown, first rectangular strips 14 are respectively fixedly connected to the sides of the side plates 1 away from the U-shaped pointed blocks 12. A rectangular frame 142 is provided in the middle of the two first rectangular strips 14, and a filter screen 145 is fixedly connected to the middle of the rectangular frame 142.

[0028] Specifically, when driving the rotation of the dial 231 to dial the silt to both sides, there may be a little silt, impurities and water mixed and not conveyed and removed by the spiral blade 21. A filter screen 145 is provided on one side to further filter the water in the water channel.

[0029] As Figure 6 shown, rectangular grooves 141 are respectively formed on the opposite sides of the two first rectangular strips 14. First cylindrical blocks 143 are respectively fixedly connected to the lower ends of the two sides of the rectangular frame 142. The first cylindrical blocks 143 are slidably arranged inside the rectangular grooves 141. First bolts 144 are respectively threadedly connected to the upper ends of the first rectangular strips 14, and the first bolts 144 are used to fix the first rectangular strips 14 and the rectangular frame 142.

[0030] Specifically, after the silt is discharged into the rectangular cylinder 22, driving the rotation of the arc blade 223 hooks out the plastic bags in the silt, and then discharges them between the two side plates 1. The plastic bags are held by the filter screen 145. At the same time, the filter screen 145 can further remove the impurities in the water in the water channel. The collected impurities can be collected uniformly. After the collection is completed, drive the first bolt 144 to rotate, separate the rectangular frame 142 from the first rectangular strip 14, then drive the first cylindrical block 143 to slide upward, then drive the rectangular frame 142 to rotate so that the filter screen 145 is located at the lower end, and then remove the plastic bags and impurities in the filter screen 145.

[0031] As Figure 5As shown in the figure, first cylindrical bars 133 are rotatably arranged on both sides of the upper end of the first rectangular plate 13. A plurality of pointed bars 134 are fixedly connected to the middle of the first cylindrical bars 133. The pointed bars 134 are respectively located between two adjacent arc-shaped blades 223. One side of the upper end of the first rectangular plate 13 is rotatably connected to a second rectangular plate 131 through a torsion spring. A baffle 132 is fixedly connected to one side of the upper end of the second rectangular plate 131.

[0032] Specifically, when the arc-shaped blades 223 hook out more plastic bags, it is necessary to remove the plastic bags from the arc-shaped blades 223 in time to prevent the plastic bags from falling off and affecting the subsequent effect of the arc-shaped blades 223 in removing plastic bags. By arranging the pointed bars 134 between the arc-shaped blades 223, after the arc-shaped blades 223 hook out the plastic bags, the arc-shaped blades 223 rotate and convey the plastic bags to the upper ends of the pointed bars 134. When there are more plastic bags at the upper ends of the pointed bars 134, drive the first cylindrical bars 133 to rotate to drive the pointed bars 134 to rotate towards the upper end of the second rectangular plate 131, and at the same time drive the second rectangular plate 131 to be parallel to the first rectangular plate 13, so that the plastic bags fall on the upper end of the second rectangular plate 131. Then drive the pointed bars 134 away from the second rectangular plate 131. Under the action of the torsion spring, drive the second rectangular plate 131 to tilt to one side, so that the plastic bags on the upper end of the second rectangular plate 131 slide down between the two side plates 1 and are then caught by the filter screen 145, and the plastic bags can be removed during the dredging process.

[0033] As Figure 1 shown in the figure, second rectangular bars 17 are respectively arranged on both sides of the side plate 1. The second rectangular bars 17 are slidably arranged in the middle of the first rectangular blocks 172. The first rectangular blocks 172 are fixedly connected to the side plate 1. Wheels 171 are rotatably arranged at the lower ends of the second rectangular bars 17. A third rectangular plate 173 is fixedly connected to the upper ends of a plurality of the second rectangular bars 17. A threaded rod 174 is threadedly connected to the middle of the third rectangular plate 173. The threaded rod 174 is rotatably arranged on the upper end of the first rectangular plate 13.

[0034] Specifically, during the dredging work, make the wheels 171 located on both sides of the upper end of the water channel and make the side plate 1 located inside the water channel. By driving the threaded rod 174 to rotate, drive the third rectangular plate 173 to move downward, and at the same time drive the second rectangular bars 17 to slide in the middle of the first rectangular blocks 172, and the distance between the wheels 171 and the water channel can be adjusted according to the depth of the water channel.

[0035] As Figure 1 shown in the figure, support legs 15 are fixedly connected to the lower ends of the first rectangular bars 14. Support bars 16 are fixedly connected to the upper ends of the first rectangular bars 14. A grip bar 161 is fixedly connected between the two support bars 16.

[0036] Specifically, by pushing the grip rod 161, the side plate 1 can be driven to move in the water channel, and the support legs 15 can support the side plate 1 to keep the lower end of the inclined plate 11 always close to the bottom of the water channel.

[0037] Embodiment 2: As Figure 7 shown, compared with Embodiment 1, another implementation manner of the present invention is: a weeding component is provided on the side of the side plate 1 away from the filter screen 145. The weeding component includes a plurality of arc-shaped blades 3. The plurality of arc-shaped blades 3 are respectively fixedly connected to the outside of the fourth cylindrical bar 31. Connecting rods 33 are respectively rotatably connected to both sides of the fourth cylindrical bar 31. The ends of the connecting rods 33 away from the fourth cylindrical bar 31 are respectively rotatably connected to second rectangular blocks 34. A fifth cylindrical bar 331 is fixedly connected between the two connecting rods 33. Both ends of the fifth cylindrical bar 331 respectively penetrate through the second rectangular blocks 34. The second rectangular blocks 34 are respectively fixedly connected to the side plate 1. A second bolt 341 is threadedly connected to the upper end of the second rectangular block 34.

[0038] Specifically, when the water channel has not been used for a long time, a lot of weeds will grow on the surface of the water in the water channel. When directly carrying out the dredging work, the weeds will be wound around the spiral blade 21, thus increasing the number of machine repairs. By arranging a plurality of arc-shaped blades 3 on the advancing side of the spiral blade 21, driving the fourth cylindrical bar 31 to rotate drives the plurality of arc-shaped blades 3 to rotate, stirring and crushing the weeds in the water channel, and then conveying them by the spiral blade 21, discharging the silt and the crushed weeds to both sides of the water channel. Since the heights of the water channels are different, by driving the connecting rods 33 to rotate on one side of the second rectangular block 34, the height of the arc-shaped blades 3 can be adjusted to remove weeds at different heights.

[0039] As Figure 7 shown, both ends of the fourth cylindrical bar 31 respectively penetrate through the connecting rods 33, and second cylindrical blocks 32 are respectively fixedly connected to both ends of the fourth cylindrical bar 31. A plurality of pointed nails 321 are respectively fixedly connected to the outside of the second cylindrical blocks 32.

[0040] Specifically, when dredging the water channel, place the second cylindrical blocks 32 on both sides of the upper end of the water channel, and then push the grip rod 161 to drive the side plate 1 to move in the water channel for dredging work. During the movement, drive the second cylindrical blocks 32 to rotate on both sides of the upper end of the water channel through the pointed nails 321. The second cylindrical blocks 32 drive the plurality of arc-shaped blades 3 to rotate through the fourth cylindrical bar 31. The pointed nails 321 are used to increase the friction of the second cylindrical blocks 32 to ensure that when driving the side plate 1 to move, the second cylindrical blocks 32 can be driven to rotate.

[0041] Working principle: When dredging the water channel, place the side plate 1 into the water channel, with the side plate 1 located on both sides inside the water channel, the inclined plate 11 at the bottom inside the water channel, and the wheels 171 on both sides at the upper end of the water channel. By driving the rotation of the threaded rod 174, drive the third rectangular plate 173 to move downward, and at the same time drive the second rectangular strip 17 to slide in the middle of the first rectangular block 172. The distance between the wheel 171 and the water channel can be adjusted according to the depth of the water channel. Place the second cylindrical block 32 on both sides at the upper end of the water channel, and then push the grip rod 161 to drive the side plate 1 to move in the water channel, driving the U-shaped pointed block 12 to stick to the bottom and both sides of the water channel. The U-shaped pointed block 12 can scrape the silt on the inner bottom and both sides of the water channel. By pushing the grip rod 161, the side plate 1 can be driven to move in the water channel. During the movement, the second cylindrical block 32 rotates through the pointed nails 321 on both sides at the upper end of the water channel. The second cylindrical block 32 drives several arc-shaped blades 3 to rotate through the fourth cylindrical strip 31 to stir and break the weeds in the water channel. At the same time, drive the third cylindrical strips 23 on both sides to rotate and drive the paddles 231 to rotate to dial the silt in the middle to the arc-shaped blocks 2 on both sides. At the same time, drive the spiral blade 21 to rotate to drive the silt inside the arc-shaped block 2 to be conveyed upward until it is conveyed into the rectangular cylinder 22. Then drive the arc-shaped blade 223 to rotate to hook out the plastic bags in the silt, so that the plastic bags are discharged from the rectangular hole 221. At this time, the silt in the rectangular cylinder 22 still contains a certain amount of water. The filter plate 224 filters the water in the silt, and the filtered silt is then discharged from the rectangular cylinder 22. When the arc-shaped blade 223 rotates, it can scrape the filter plate 224 to prevent the filter plate 224 from being blocked. The filtered water is then discharged into the water channel through the connecting pipe 225; When the arc-shaped blade 223 hooks out more plastic bags, it is necessary to remove the plastic bags from the arc-shaped blade 223 in time to prevent the plastic bags from falling off and affecting the subsequent effect of the arc-shaped blade 223 in removing plastic bags. By arranging the pointed strip 134 between the arc-shaped blades 223, after the arc-shaped blade 223 hooks out the plastic bags, the arc-shaped blade 223 rotates and conveys the plastic bags to the upper end of the pointed strip 134. When there are more plastic bags at the upper end of the pointed strip 134, drive the first cylindrical strip 133 to rotate to drive the pointed strip 134 to rotate towards the upper end of the second rectangular plate 131, and at the same time drive the second rectangular plate 131 to be parallel to the first rectangular plate 13, so that the plastic bags fall on the upper end of the second rectangular plate 131. Then drive the pointed strip 134 to move away from the second rectangular plate 131. Under the action of the torsion spring, drive the second rectangular plate 131 to tilt to one side, so that the plastic bags at the upper end of the second rectangular plate 131 slide down between the two side plates 1 and are then caught by the filter screen 145. The plastic bags can be removed during the dredging process.
