A water-fertilizer integrated sprinkler belt reeling device for saline-alkali land

Abstract

The present invention relates to the technical field of winding devices, and discloses a saline-alkali land water-fertilizer integrated sprinkler belt winding device, comprising a base, wherein two support plates are symmetrically fixedly installed on the upper surface of the base, and a winding roller is rotatably installed between the two support plates. The present invention allows the air inside the compression box to be discharged from the second one-way air outlet valve through the arrangement of a first one-way air inlet valve and a second one-way air outlet valve, and allows the piston plate to pump the inside of the negative pressure box into negative pressure through a hose through the arrangement of the first one-way air outlet valve and the second one-way air inlet valve. Since the rubber pressure roller does not completely compact the two ends of the drip irrigation belt, a small amount of air can flow inside the drip irrigation belt. At this time, the residual air inside the drip irrigation belt located inside the negative pressure box will be discharged from the water spray hole. The device can discharge the soil inside the water spray hole on the surface of the sprinkler belt to avoid blocking the water spray hole after the soil is dried, which is convenient for subsequent use.

Description

Technical Field

[0001] The invention relates to the technical field of winding devices, and in particular to a water-fertilizer integrated sprinkler belt winding device for saline-alkali land. Background Art

[0002] Irrigation generally refers to watering, which is a way of applying fertilizer and water in agriculture. Channel water replenishment, sprinkler irrigation and drip irrigation are the main forms of irrigation. According to the purpose, method, timing and amount of water, there can be different classifications. Sprinkler belt is a new type of micro-irrigation equipment, also known as "sprinkler belt" or "sprinkler pipe". It is a lightweight and easy-to-install equipment that can accurately irrigate farmland or gardens. Sprinkler belts are usually made of plastic or rubber and have different sizes and spraying modes to meet different irrigation needs. The characteristics of sprinkler belts are that they can spray water evenly, save water resources, and at the same time increase crop yields and reduce pests and diseases. When using sprinkler belts, they need to be laid at the roots of crops and spray water out through water pumps or gravity.

[0003] The existing winding device for sprinkler belt and its use method (publication number: CN117303110A) have at least the following disadvantages:

[0004] When the above patent is in use, the blocking cylinder is started to rotate the blocking block, so that one of the storage cylinders rolls inside the main limiting rail and the secondary limiting rail, and then the storage cylinder is constrained by the secondary limiting rail to the central axis of the limiting ring, and the moving cylinder is started to clamp the protruding block with the clamping cylinder, and the winding motor starts the driving gear to drive the driven gear and the clamping cylinder to rotate, and then the clamping cylinder drives the protruding block and the storage cylinder to rotate, completing the storage action of the sprinkler belt. Since there are many tiny water spray holes on the surface of the drip irrigation belt, when the drip irrigation belt is irrigated in the land, soil particles will stick to the surface, and the soil particles will fall into the water spray holes to block the water spray holes. The above patent can only clean the soil particles remaining on the surface of the drip irrigation belt, but cannot clean the soil dirt inside the water spray holes. The soil dirt will dry in the water spray holes on the surface of the drip irrigation belt, blocking them and affecting subsequent use. Summary of the invention

A compression box 25 is fixedly installed on the upper surface of the base 1, and a piston plate 2504 is slidably installed between the inner walls of the compression box 25. Air pipe joints are fixedly installed on the outer surfaces of the opposite sides of the negative pressure box 14, and a first one-way air outlet valve 2507 is fixedly installed on the outer surface of one side of the compression box 25 near the top, and the outer surface of the other side of the compression box 25 near the top is fixedly installed. A second one-way air inlet valve 2509 is fixedly installed on the surface, a first one-way air inlet valve 2506 is fixedly installed on the outer surface of one side of the compression box 25 near the bottom, and a second one-way air outlet valve 2508 is fixedly installed on the outer surface of the other side of the compression box 25 near the bottom. The first one-way air inlet valve 2506 is connected to one of the air pipe joints through a hose 2503, and the second one-way air inlet valve 2509 is connected to the other air pipe joint through a hose 2503. A fixing rod 2501 is fixedly installed between the two rotating arms 4. The fixing rod A connecting rod 2502 is rotatably installed on the outer surface of 2501, and a square slide bar 2505 is fixedly installed on the upper surface of the piston plate 2504. The top of the square slide bar 2505 passes through the top of the compression box 25 and is slidably installed therewith. The top of the square slide bar 2505 is rotatably installed with the bottom end of the connecting rod 2502. A first one-way air outlet valve 2507 and a second one-way air inlet valve 2509 are arranged above the piston plate 2504, and a first one-way air inlet valve 2506 and a second one-way air outlet valve 2508 are arranged below the piston plate 2504.

[0033] The reciprocating up and down motion of the rotating arm 4 drives the fixing rod 2501 to reciprocate up and down, and the fixing rod 2501 drives the piston plate 2504 to slide up and down along the inner wall of the compression box 25 through the connecting rod 2502 and the square sliding rod 2505. When the piston plate 2504 slides downward, the air inside the compression box 25 is discharged from the second one-way air outlet valve 2508 through the setting of the first one-way air outlet valve 2507 and the second one-way air inlet valve 2509, so that the piston plate 2504 draws the inside of the negative pressure box 14 into a negative pressure through the hose 2503. Since the rubber pressure roller 1402 has not completely compacted the two ends of the drip irrigation belt, a small amount of air can flow inside the drip irrigation belt. At this time, the residual air inside the drip irrigation belt inside the negative pressure box 14 will be discharged from the water spray holes. The device can be used to discharge the soil inside the water spray holes on the surface of the sprinkler irrigation belt to avoid the water spray holes being blocked by the soil after drying, which is convenient for subsequent use. As the drip irrigation belt is continuously wound up, the water spray holes on its outer surface can be continuously cleaned; the brush plate 1401 can be used to sweep away the soil and dirt cleaned from the surface of the drip irrigation belt; when the piston plate 2504 moves upward, the interior of the negative pressure box 14 is also pumped into negative pressure.

[0035] When the drip irrigation belt is in a negative pressure state, the drip irrigation belt located inside the negative pressure box 14 will expand due to the residual air inside it. The expansion of the drip irrigation belt allows the disc 1502 to drive the telescopic column 1501 to extend out of the outer surface of the sealing cover 15. Through this device, the operator can intuitively see whether the inside of the negative pressure box 14 is in a negative pressure state.

[0036] In this embodiment, two support plates 5 are symmetrically fixedly installed on the upper surface of the base 1, and a turntable 20 is rotatably installed on the outer surface of the adjacent side of the top of the two support plates 5. A driving column 21 is fixedly installed on the outer surface of the turntable 20 close to the rotating arm 4. The driving column 21 is arranged at an eccentric position of the turntable 20. A driving groove 22 is penetrated through the outer surface of the rotating arm 4 close to the turntable 20. The driving column 21 is slidably installed on the inner wall of the driving groove 22.

[0038] In this embodiment, a fourth pulley 705 is fixedly installed on the outer surface of the transmission shaft 16, and a driving gear 702 is rotatably installed on the outer surface of one support plate 3 close to the fourth pulley 705, and a third pulley 703 is fixedly installed on the outer surface of the rotation center of the driving gear 702, and a second belt 704 is sleeved on the outer surfaces of the third pulley 703 and the fourth pulley 705, and a driving motor 7 is fixedly installed on the outer surface of one side of the support plate 3, and the output end of the driving motor 7 is fixedly installed on the outer surface of the support plate 3 and the rotation center of the driving gear 702, and a driven gear 701 is fixedly installed on the outer surface of the winding roller 2 close to one end of the driving gear 702, and the driven gear 701 is meshed with the driving gear 702.

[0039] When the sprinkler belt is rolled up, the driving motor 7 drives the driving gear 702 to rotate, and the driving gear 702 drives the driven gear 701 to rotate, so that the driven gear 701 drives the winding roller 2 to rotate, and the sprinkler belt is wound around its outer surface through the rotation of the winding roller 2 to be rolled up.

[0040] In this embodiment, a socket 202 is provided on the circumferential outer surface of the winding roller 2, and both ends of the winding roller 2 pass through the outer surface of the support plate 3.

A baffle 8 is fixedly installed on one end of one of the locking shafts 10. A first spring 9 is sleeved on the outer surface of the locking shaft 10. The first spring 9 One end is fixedly connected to the baffle 8, the other end of the first spring 9 is fixedly connected to the end face of one end of the winding roller 2, a pull block 11 is fixedly installed on the end face of one end of the other locking shaft 10, and a clamping column 12 is fixedly installed on the circumferential outer surface of the locking shaft 10 close to the pull block 11, and two clamping grooves 13 are symmetrically provided on the end face of the other end of the winding roller 2, and the two clamping grooves 13 are vertically aligned up and down, and the clamping column 12 is clamped into the inside of the clamping groove 13 by the action force of the first spring 9, and the position of the locking shaft 10 is limited by this arrangement to prevent it from rotating arbitrarily inside the winding roller 2.

[0041] By pulling the pull block 11, the locking shaft 10 drives the clamping column 12 to slide out from the inner wall of one clamping groove 13, and then the operator rotates the locking shaft 10 to drive the clamping column 12 to slide into the inside of the other clamping groove 13. The rotation of the locking shaft 10 drives the semi-cylinder 201 to rotate to a direction of 180°, so that one end of the sprinkler belt is fixed inside the socket 202. The device is convenient for quickly fixing the sprinkler belt.

[0042] In this embodiment, the other ends of the two rotating arms 4 are fixedly installed with mounting plates 6, and the outer surfaces of the two mounting plates 6 are symmetrically penetrated with two slide grooves 601, and the inner walls of the two slide grooves 601 are slidably installed with I-shaped sliders 602, wherein an upper pressure wheel 23 is rotatably installed between the two I-shaped sliders 602, and a lower pressure wheel 24 is rotatably installed between the other two I-shaped sliders 602. The upper pressure wheel 23 is arranged above the lower pressure wheel 24, and the outer surfaces of the upper pressure wheel 23 and the lower pressure wheel 24 are abutted. Two limiting rings are symmetrically arranged on the circumferential outer surface of the upper pressure wheel 23, and two limiting grooves matching the limiting rings are arranged on the circumferential outer surface of the lower pressure wheel 24, and the upper surfaces of the two I-shaped sliders 602 located on the upper pressure wheel 23 are fixedly installed with third springs 603. A third spring 603 is fixedly installed on the lower surface of the two I-shaped sliders 602 located on the lower pressure wheel 24, and the other end of the third spring 603 is fixedly connected to the inner wall of the slide groove 601. A fixing plate 26 is fixedly installed between the outer surfaces of the two mounting plates 6 near the bottom ends. The fixing plate 26 is symmetrically rotated relative to the outer surface of one side of the winding roller 2 and has two L-shaped levers 27 installed. The outer surfaces of the two L-shaped levers 27 located at the rotation center are fixedly installed with fan gears 28, and the two fan gears 28 are meshed with each other. A connecting plate is fixedly installed on the bottom end of one of the L-shaped levers 27, and a pull rope 30 is fixedly installed on the other end of the connecting plate. The bottom end of the pull rope 30 is fixedly installed on the upper surface of the base 1, and a tension spring 29 is fixedly installed between the outer surfaces of the two L-shaped levers 27 near the top.

[0043] When the rotating arm 4 moves downward, due to the loosening of the pull rope 30, the two L-shaped levers 27 move closer to each other under the action of the tension spring 29 and the fan gear 28. When the rotating arm 4 moves downward, the drip irrigation tape will leave the top of the L-shaped lever 27. When the rotating arm 4 moves upward, due to the pulling of the pull rope 30, the two L-shaped levers 27 move away from each other. At this time, because the rotating arm 4 moves upward, the top of the L-shaped lever 27 will contact the lower surface of the drip irrigation tape. Through this device, the two sides of the drip irrigation tape can be unfolded to avoid the edges of the drip irrigation tape being folded together when winding, which affects the subsequent winding.

[0044] In this embodiment, the outer surface of the upper pressure wheel 23 is concave, and the outer surface of the lower pressure wheel 24 is convex; the upper and lower movement limit positions of the piston plate 2504 are between the second one-way air inlet valve 2509 and the second one-way air outlet valve 2508; it should be noted that a gap is provided between the two rubber pressure rollers 1402 and the bottom wall of the negative pressure box 14, and the sprinkler belt is inserted between the gap.

[0045] It should be noted that when the present invention is in use, the operator passes one end of the irrigation belt between the lower pressure wheel 24 and the upper pressure wheel 23, and then inserts it from one of the openings 1403 to the bottom of the two rubber pressure rollers 1402 to abut against their surfaces, and then passes it out from the other opening 1403 to insert one end of the irrigation belt into the inside of the socket 202; the operator pulls the pull block 11 to make the locking shaft 10 drive the clamping column 12 to slide out from the inner wall of one slot 13, and then the operator rotates the locking shaft 10 to drive the clamping column 12 to slide into the inside of the other slot 13, and the rotation of the locking shaft 10 drives the semi-cylinder 201 to rotate to a direction of 180°, so that it fixes one end of the irrigation belt inside the socket 202, and the device is convenient for quickly fixing the irrigation belt;

[0046] When the irrigation belt is rolled up, the driving motor 7 drives the driving gear 702 to rotate, and the driving gear 702 drives the driven gear 701 to rotate, so that the driven gear 701 drives the winding roller 2 to rotate, and the irrigation belt is wound around the outer surface of the winding roller 2 through the rotation of the winding roller 2 to be rolled up;

[0047] The third pulley 703 is driven to rotate by the driven gear 701, the third pulley 703 drives the fourth pulley 705 to rotate through the second belt 704, the fourth pulley 705 drives the transmission shaft 16 to rotate, the transmission shaft 16 drives the first pulley 17 to rotate, the first pulley 17 drives the second pulley 19 to rotate through the first belt 18, the second pulley 19 drives the turntable 20 to rotate, the turntable 20 drives the rotating arm 4 to swing up and down through the driving column 21 and the driving groove 22, the rotating arm 4 swings the drip irrigation belt up and down through the lower pressure wheel 24 and the upper pressure wheel 23, the drip irrigation belt can be unfolded by this device, and at the same time, the soil bonded to the surface of the drip irrigation belt can be shaken off by shaking;

[0048] When the rotating arm 4 moves downward, due to the loosening of the pull rope 30, the two L-shaped levers 27 move closer to each other under the action of the tension spring 29 and the fan gear 28. When the rotating arm 4 moves downward, the drip irrigation belt will leave the top of the L-shaped lever 27. When the rotating arm 4 moves upward, due to the pulling of the pull rope 30, the two L-shaped levers 27 move away from each other. At this time, because the rotating arm 4 moves upward, the top of the L-shaped lever 27 will contact the lower surface of the drip irrigation belt. Through this device, the two sides of the drip irrigation belt can be unfolded to avoid the edges of the drip irrigation belt being folded together when winding, which affects the subsequent winding.

[0049] The reciprocating up and down motion of the rotating arm 4 drives the fixing rod 2501 to reciprocate up and down, and the fixing rod 2501 drives the piston plate 2504 to slide up and down along the inner wall of the compression box 25 through the connecting rod 2502 and the square sliding rod 2505. When the piston plate 2504 slides downward, the air inside the compression box 25 is discharged from the second one-way air outlet valve 2508 through the setting of the first one-way air outlet valve 2507 and the second one-way air inlet valve 2509, so that the piston plate 2504 draws the inside of the negative pressure box 14 into a negative pressure through the hose 2503. , because the rubber pressure roller 1402 does not completely compact the two ends of the drip irrigation belt, a small amount of air can flow inside the drip irrigation belt. At this time, the residual air inside the drip irrigation belt inside the negative pressure box 14 will be discharged from the water spray holes. The soil inside the water spray holes on the surface of the sprinkler irrigation belt can be discharged through this device to avoid the water spray holes being blocked by the soil after drying, which is convenient for subsequent use. As the drip irrigation belt is continuously rolled up, the water spray holes on its outer surface can be continuously cleaned; the soil dirt cleaned from the surface of the drip irrigation belt can be swept away by the brush plate 1401; when the piston plate 2504 moves upward, the interior of the negative pressure box 14 is also pumped into negative pressure;

[0050] When the drip irrigation belt is in a negative pressure state, the drip irrigation belt located inside the negative pressure box 14 will expand due to the residual air inside it. The expansion of the drip irrigation belt allows the disc 1502 to drive the telescopic column 1501 to extend out of the outer surface of the sealing cover 15. Through this device, the operator can intuitively see whether the inside of the negative pressure box 14 is in a negative pressure state.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
