Description

Technical Field

[0001] The invention belongs to the technical field of soil measurement sample collection, and in particular relates to a gravity flow sloping farmland in-situ soil leaching solution collector. Background Art

[0002] In-situ soil leaching solution of cultivated land usually refers to groundwater or soil solution formed by irrigation or natural precipitation in the cultivated land, which dissolves some nutrients and minerals in the soil. This solution contains soluble nutrients in the soil and plays an important role in the absorption and utilization of plants.

[0003] In agriculture, by analyzing the composition of the in-situ soil leaching solution of cultivated land, we can understand the nutrient status of the soil and then guide agricultural production, such as the rational application of fertilizers and adjustment of soil pH to ensure the healthy growth of crops. At the same time, the composition of the soil leaching solution can also reflect the environmental status of the soil, such as heavy metal pollution, organic matter content, etc., which is also of great significance for soil environmental monitoring and environmental protection.

[0004] Most existing collectors use sand and gravel to block the suspended particles in the filtration solution. However, after long-term use, more suspended particles will remain on the surface of the sand and gravel. In addition, due to the weight of the soil itself, the filtration porosity of the sand and gravel will be reduced, which will affect the filtration and collection of the leachate solution and the collection and detection results of the leachate solution.

[0005] Based on this, the present invention designs a gravity flow sloping farmland in-situ soil leaching solution collector to solve the above problems. Summary of the invention

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In the present invention, a movable frame, a supporting net, a driving component, a flushing nozzle, a connecting gear and a stirring rod are adopted. The driving component controls the threaded cap, the intermediate block and the movable frame to move in a process where the connecting gear is controlled to mesh with the rack by a reciprocating screw rod. When the connecting gear rotates, the stirring rod is controlled to rotate. The stirring rod turns over the sand and gravel in the placement chamber, and at the same time cooperates with the high-pressure water flow sprayed by the flushing nozzle to fully clean the sand and gravel, so that the sundries or particles accumulated between the sand and gravel are washed down.

[0029] 2. In the present invention, a cam, a first magnetic block, a second magnetic block, a first elastic component, a knocking rod and a contact block are used. As the movable frame moves, the connecting gear is controlled to rotate by the rack. At this time, the rotation of the cam will control the first magnetic block to intermittently approach the second magnetic block. When the first magnetic block approaches the second magnetic block, the magnetic repulsion between the two increases to control the movable seat and the knocking rod to move away from the contact block. When the first magnetic block is controlled by the rotation of the cam to quickly move away from the second magnetic block, the elastic force of the first elastic component controls the knocking rod to quickly reset and knock on the contact block, thereby achieving knocking vibration on the movable frame, so that the sand and gravel in the placement chamber that is moving toward the nylon net is vibrated. At this time, the stirring rod in the placement chamber stops rotating, and the sand and gravel in the placement chamber gradually become dense.

When the piston plate is squeezed and moved by the moving frame, the gas in the piston frame is squeezed and discharged through the second one-way valve and the air outlet head. The discharged gas is blown under the nylon mesh through the air outlet head that moves with the moving frame, thereby achieving air blowing and cleaning of the nylon mesh from the bottom. Even if the gas cannot flow upward through the nylon mesh completely, the rapid gas blowing can be used to achieve a certain cleaning effect on the particles stuck in the nylon mesh.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Please refer to the attached Figure 1 -Attached Fig.11The present invention provides a technical solution: a gravity flow sloping farmland in-situ soil leaching solution collector, comprising an isolation cylinder 1, a middle frame 2 is connected below the isolation cylinder 1, a connecting bucket 3 is connected below the middle frame 2, a liquid collecting pipe 4 is connected below the connecting bucket 3, a collecting bucket 5 is connected to the bottom end of the liquid collecting pipe 4, an extension frame 6 is connected to both sides of the middle frame 2, a drainage pipe 7 is connected below the extension frame 6, a discharge pipe 8 is connected to the bottom ends of the two drainage pipes 7, a moving frame 10 located in the extension frame 6 is slidably connected inside the middle frame 2, two placement cavities 11 are provided inside the moving frame 10, support nets 12 are penetrated at the upper and lower positions of the moving frame 10 corresponding to the placement cavities 11, and a support net 12 is provided inside the middle frame 2. A nylon net 9 is connected to the upper side of the net 12, and a rotating stirring mechanism 13 located in the placement cavity 11 is penetrated on both sides of the mobile frame 10, and one end of the rotating stirring mechanism 13 is connected to a rotating vibration mechanism 14 arranged outside the mobile frame 10, and a rotating control mechanism 17 is connected to one side of the mobile frame 10, and the rotating control mechanism 17 is connected to the extension frame 6, and a flushing mechanism 15 is penetrated on the extension frame 6, and a piston squeezing mechanism 16 is connected to the extension frame 6, and an air outlet head 19 is penetrated on the mobile frame 10, and the piston squeezing mechanism 16 penetrates into the mobile frame 10 and is connected to the air outlet head 19, and a rack 18 is connected to the position corresponding to the rotating vibration mechanism 14 in the extension frame 6.

[0046] The rotating stirring mechanism 13 includes a connecting shaft 131 connected to the rotating vibration mechanism 14, and two first bearings 133 are arranged on the outer sleeve of the connecting shaft 131. The first bearing 133 is connected to one side of the movable frame 10, and a first bevel gear 132 is fixedly connected to the side of the connecting shaft 131. A second bevel gear 134 is meshed with the side of the first bevel gear 132, and a rotating shaft 135 is connected to the side of the second bevel gear 134 close to the movable frame 10.

[0047] The part of the side of the rotating shaft 135 located in the placement chamber 11 is connected to a stirring rod 137 for stirring sand and gravel. The stirring rod 137 is set to be cylindrical. The outer sleeve of the rotating shaft 135 is provided with a second bearing 136. The second bearing 136 is arranged on one side of the movable frame 10. The rotating shaft 135 and the stirring rod 137 are located between the support nets 12 on the upper and lower sides.

[0048] Due to the limitation of the first bearing 133 on the connecting shaft 131, the connecting shaft 131 and the first bevel gear 132 can rotate stably, and the first bevel gear 132 and the second bevel gear 134 maintain a stable meshing state. The connecting shaft 131 can control the rotation of the plurality of second bevel gears 134 and the rotating shaft 135 through the first bevel gear 132. When the rotating shaft 135 rotates, the sand and gravel in the placement cavity 11 are stirred through the stirring rod 137. When the sand and gravel are stirred, the internal gaps thereof change, which is conducive to the falling of the particles or debris accumulated therein, and is convenient for cleaning the sand and gravel.

[0049] The rotating vibration mechanism 14 includes a cam 1401, a moving seat 1404 and a contact block 1407. The cam 1401 is connected to the connecting shaft 131. The side of the cam 1401 is connected to a connecting gear 1402. The side of the cam 1401 is penetrated by a first magnetic block 1403. The side of the moving seat 1404 corresponding to the cam 1401 is connected to a second magnetic block 1405. The sides of the first magnetic block 1403 and the second magnetic block 1405 that are close to each other when the distance between them is the smallest have the same magnetism.

[0050] A knocking rod 1406 for knocking the contact block 1407 is connected to one side of the movable seat 1404 close to the cam 1401, and the contact block 1407 is located on the moving track of the knocking rod 1406. A telescopic rod 1408 is connected to the side of the movable seat 1404, and the other end of the telescopic rod 1408 is connected to a fixed block 1409. The fixed block 1409 and the contact block 1407 are both fixedly connected to the outside of the movable frame 10, and a first elastic component 1410 is provided on the outer sleeve of the telescopic rod 1408. The two ends of the first elastic component 1410 are respectively fixedly connected to the movable seat 1404 and the fixed block 1409.

[0051] By utilizing the movement of the moving frame 10 approaching the rack 18, the connecting gear 1402 that is moving is controlled to rotate by the rack 18 through meshing control. During the rotation of the cam 1401, the first magnetic block 1403 is controlled to rotate close to the second magnetic block 1405. The magnetic repulsion between the two increases, so that the moving seat 1404 and the knocking rod 1406 move away from the contact block 1407. When the first magnetic block 1403 quickly rotates away from the second magnetic block 1405, the repulsion decreases rapidly, and the first elastic component 1410 controls the moving seat 1404 and the knocking rod 1406 to quickly reset. The knocking rod 1406 quickly acts on the contact block 1407, thereby achieving knocking vibration of the contact block 1407, the moving frame 10 and the sand and gravel, so that the sand and gravel in the placement cavity 11 approaching the lower side of the nylon net 9 is vibrated and compacted;

[0052] The flushing mechanism 15 includes an extension pipe 151, which is connected to an intermediate pipe 152 at the bottom. The bottom end of the intermediate pipe 152 is connected to a transverse pipe 153. A connecting sleeve 154 is provided outside the intermediate pipe 152, and the connecting sleeve 154 is passed through the extension frame 6; the transverse pipe 153 is connected to a flushing nozzle 155 for spraying water at the bottom, and the flushing nozzle 155 is located on the upper side of the moving track of the moving frame 10.

[0053] The flushing nozzle 155 sprays high-pressure water flow downward, and the water flow impacts the surface of the sand and gravel in the supporting net 12 and the placement cavity 11. With the stirring of the sand and gravel, the gaps between the sand and gravel increase, and the water flow washes the particles accumulated on the sand and gravel down. The flushed water flows out through the drain pipe 7 and the discharge pipe 8;

[0054] The piston extrusion mechanism 16 includes a piston frame 1601 connected to the extension frame 6, a piston plate 1602 is slidably connected to the piston frame 1601, a first one-way valve 1603 is connected to the piston frame 1601, an air inlet pipe 1604 is connected to the first one-way valve 1603, a fixed sleeve 1605 is provided on the outer sleeve of the air inlet pipe 1604, and the fixed sleeve 1605 is provided on the extension frame 6, and two air outlet pipes 1606 are connected to the side of the piston frame 1601, and a second one-way valve 1606 is provided on the outside of the air outlet pipe 1606. To valve 1607, the air outlet pipe 1606 is located in the movable frame 10 and is connected to the air outlet head 19; the side of the piston plate 1602 close to the movable frame 10 is connected with a movable rod 1609, the movable rod 1609 penetrates and is slidably arranged on the side of the piston frame 1601, and the end of the movable rod 1609 located outside the piston frame 1601 is connected with a contact circular plate 1610, and the side of the piston plate 1602 is connected with a second elastic component 1608, and the second elastic component 1608 is connected in the piston frame 1601.

[0055] When the moving frame 10 moves away from the contact circular plate 1610, the second elastic component 1608 controls the piston plate 1602 to reset. At this time, the piston plate 1602 draws external air into the piston frame 1601 through the first one-way valve 1603 and the air inlet pipe 1604, so as to replenish the gas in the piston frame 1601; when the moving frame 10 moves close to the contact circular plate 1610, the moving frame 10 squeezes the contact circular plate 1610, the moving rod 1609 and the piston plate 1602 to reset. During the movement of the piston plate 1602, the gas in the piston frame 1601 is squeezed, and the gas is ejected upward through the second one-way valve 1607, the air outlet pipe 1606 and the air outlet head 19. The ejected gas is quickly blown under the nylon mesh 9 as the moving frame 10 moves, so as to perform a certain reverse blowing and cleaning effect on the debris or particles stuck inside the nylon mesh 9.

[0056] The rotation control mechanism 17 includes a driving assembly 171 fixedly connected to the extension frame 6, the output shaft of the driving assembly 171 is connected to a reciprocating screw 172, the reciprocating screw 172 is externally threadedly connected to a threaded cap 173, the threaded cap 173 is externally connected to an intermediate block 174, and the intermediate block 174 is fixedly connected to the side of the moving frame 10.

[0057] The driving assembly 171 utilizes the reciprocating screw rod 172 to control the movement of the threaded cap 173, the intermediate block 174 and the movable frame 10. The positions of the sand and gravel in the two placement chambers 11 are swapped, so that the sand and gravel on one side can be cleaned while the sand and gravel on the other side are replaced to the filtering position. The work can be maintained continuously, and the cleaning and replacement operations are quick and convenient without causing a significant impact on the collection efficiency of the eluent.

[0058] Working principle, when using:

[0059] The isolation cylinder 1 is buried in the soil, and the top of the extension pipe 151 and the air inlet pipe 1604 are exposed to the ground. The discharge pipe 8 and the collection bucket 5 are located on the outer side of the slope of the gravity flow sloping farmland. The solution in the soil of the isolation cylinder 1 flows downward and enters the middle frame 2. After being filtered by the nylon net 9, the support net 12 and the sand and gravel in the placement cavity 11, the solution flows into the collection bucket 5 through the liquid collecting pipe 4 to collect the leaching solution.

[0060] When it is necessary to clean the sand and gravel, the driving component 171 is directly controlled to work, and the driving component 171 controls the reciprocating screw rod 172 to rotate. At the same time, the reciprocating screw rod 172 uses the threaded action to control the threaded cap 173, the middle block 174 and the moving frame 10 to move to the right. When the moving frame 10 moves away from the contact circular plate 1610 on the left, the second elastic component 1608 controls the piston plate 1602 to reset. At this time, the piston plate 1602 sucks the outside air into the piston frame 1601 through the first one-way valve 1603 and the air inlet pipe 1604 to replenish the gas in the piston frame 1601. During the movement of the moving frame 10, the connecting gear 1402 contacts the rack 18. At this time, the moving connecting gear 1402 is controlled to rotate by the rack 18;

[0061] The connecting gear 1402 controls the cam 1401, the connecting shaft 131 and the first bevel gear 132 to rotate. During the rotation of the first bevel gear 132, the second bevel gear 134, the rotating shaft 135 and the stirring rod 137 are controlled to rotate. The stirring rod 137 rotates to stir the sand and gravel in the placement chamber 11. The flushing nozzle 155 sprays a high-pressure water flow downward. The water flow impacts the support net 12 and the surface of the sand and gravel in the placement chamber 11. With the stirring of the sand and gravel, the gap between the sand and gravel increases. The water flow washes the particles accumulated on the sand and gravel down, and the flushed water flows out through the drain pipe 7 and the discharge pipe 8. At the cam 1 During the rotation of 401, the first magnetic block 1403 is controlled to rotate close to the second magnetic block 1405, and the magnetic repulsion between the two increases, so that the moving seat 1404 and the knocking rod 1406 move away from the contact block 1407. When the first magnetic block 1403 rotates quickly away from the second magnetic block 1405, the repulsion decreases quickly, and the first elastic component 1410 controls the moving seat 1404 and the knocking rod 1406 to quickly reset, and the knocking rod 1406 quickly acts on the contact block 1407, so as to achieve knocking vibration of the contact block 1407, the moving frame 10 and the sand and gravel, so that the sand and gravel in the placement cavity 11 are vibrated and compacted;

[0062] When the movable frame 10 moves close to the contact circular plate 1610, the movable frame 10 squeezes the contact circular plate 1610, the movable rod 1609 and the piston plate 1602 to reset, and the piston plate 1602 squeezes the gas in the piston frame 1601 during the movement, and the gas is ejected upward through the second one-way valve 1607, the air outlet pipe 1606 and the air outlet head 19. The ejected gas is quickly blown under the nylon mesh 9 as the movable frame 10 moves, and the debris or particles stuck in the inside of the nylon mesh 9 are blown in the opposite direction to clean them, until the left support net 12 moves to the bottom of the nylon mesh 9, and the control drive assembly 171 stops working. At this time, the cleaning and replacement of the sand and gravel on the right are completed, and the collection of the leaching solution can continue.

[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
