Description

Technical Field

[0001] The invention relates to the technical field of water pipe reeling, and in particular to a water-fertilizer integrated irrigation water pipe reeling device. Background Art

[0002] Water-fertilizer used to refer to fertilizer formed by mixing human feces and urine with water after they have been decomposed. Now it often refers to water-soluble fertilizer, a multi-component compound fertilizer that can be completely soluble in water. It can dissolve quickly in water, is more easily absorbed by crops, and has a relatively high absorption and utilization rate. More importantly, it can be used in facility agriculture such as sprinkler and drip irrigation to achieve water-fertilizer integration. Therefore, a water pipe winding device is required when irrigating with water and fertilizer.

[0003] The existing Chinese patent with publication number CN111891848A discloses a winding device, and particularly relates to a vegetable field watering pipe winding device, providing a vegetable field watering pipe winding device that can automatically wind and clean the water pipe, reduce labor intensity, and facilitate the removal of the water pipe. The technical scheme is: a vegetable field watering pipe winding device, including a cart and a roller group, the left and right sides of the lower part of the cart are rotatably connected with the roller group; a winding mechanism, a winding mechanism is provided on the right front side of the top of the cart; a take-out mechanism, a take-out mechanism is provided on the right rear side of the top of the cart, and the winding mechanism can contact the take-out mechanism. The take-out mechanism cooperates with the winding mechanism to clamp the water pipe nozzle, so that the triangular claw quickly collects the water pipe. When the water pipe is collected, the take-out mechanism cooperates with the push-out assembly, people remove the fixed plate, and the push rod will loosen the tightly wound water pipe, so that the collected water pipe can be quickly removed.

[0004] In the prior art, the recycling of water pipes needs to pay attention to the dirt and other debris on the outside of the water pipes. Based on this problem, the above technical solution proposes relevant improvements, which can greatly reduce the labor intensity. When applied to the irrigation of water and fertilizer, since water and fertilizer need to dissolve many solid substances, after the irrigation is completed, the water and fertilizer will form a certain residue in the water pipe. During the winding process, if there is still residue in the water pipe after the winding is completed, mold will occur in the water pipe, causing the water and fertilizer to be contaminated when used next time.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0041] The present invention will be further described below in conjunction with the embodiments. Example

[0042] Reference Figures 1 to 10 A water-fertilizer integrated irrigation water pipe reeling device comprises a base 1 and a reeling wheel 2, wherein the reeling wheel 2 is rotatably connected to the top of the base 1 through a bracket, and the rotating shaft of the reeling wheel 2 is connected by an external driving mechanism. A support frame 3 is installed on the base 1, and a squeezing component 4 is installed on the top of the support frame 3, and the squeezing component 4 is used to clamp the position of the water pipe and produce a squeezing effect on the water pipe;

[0043] By adopting the extrusion component 4, the water pipe can be squeezed during the process of winding the water pipe to help the water pipe discharge the residue in the water pipe. At the same time, the pressing roller 405 in the extrusion component 4 will also press the water pipe in front of the extrusion plate 4011 to avoid excessive accumulation of residue in the water pipe in front of the extrusion plate 4011, thereby helping the water pipe to be wound up without obstruction.

[0044] The extrusion assembly 4 includes a piston cylinder 402 as an elastic support and an extrusion frame 401 for clamping the water pipe. The extrusion frame 401 includes a fixed plate 4012 as two side plates and an extrusion plate 4011 in an upper and lower position. There is a gap between the two extrusion plates 4011, and the gap is used for passing the water pipe. When the water pipe passes between the two extrusion plates 4011, it is pressed by the two extrusion plates 4011. The piston cylinder 402 has a sliding rod 409 slidably installed in the piston cylinder 402, and the sliding rod 409 is installed on the rear side of the fixed plate 4012.

[0045] In the prior art, the focus of winding up water pipes is mostly on cleaning the debris on the outside of the water pipes. However, when the water pipes used for water and fertilizer irrigation are wound up, if the residues in the water pipes cannot be cleaned in time, bacteria or mold will grow inside the water pipes during the placement of the water pipes, and this phenomenon will affect the normal use of the subsequent water pipes. In order to solve the above technical problems, the present application proposes the following improvements.

[0046] Specifically, the extrusion assembly 4 also includes two groups of rotating connecting plates 404 installed on the fixed plate 4012, the number of the two groups of rotating connecting plates 404 is two, and a pressing roller 405 is rotatably connected between the two opposite rotating connecting plates 404, and the pressing roller 405 has multiple vertical plates for rolling in the up and down directions of the water pipe.

[0047] The rotation of the winding wheel 2 can be achieved manually or by an external motor. The technology for driving the winding wheel 2 to rotate belongs to the prior art and will not be described in detail here. The specific driving method is not shown in the drawings of the specification. Before the winding wheel 2 rotates and reels the water pipe, the end of the water pipe needs to pass through the two squeezing plates 4011 and then be wound around the winding wheel 2. During the rotation of the winding wheel 2, the water pipe will be clamped and squeezed by the two squeezing plates 4011, so that the water pipe is flattened under the squeezing, the internal space of the water pipe is compressed, and the residue inside the water pipe is squeezed out. As the winding wheel 2 rotates, the water pipe will be continuously reeled on the winding wheel 2. At the same time, under the squeezing of the squeezing plate 4011, the residue will be concentrated in the front part of the squeezing plate 4011. What is expressed here is the position of the water pipe relative to the squeezing plate 4011, not that the residue is on the squeezing plate 4011. At the same time, before the water pipe passes through the squeezing plate 4011, it will first contact the upper and lower sets of pressing rollers 405. The contact between the water pipes, during the horizontal movement of the water pipe, the pressing roller 405 will rotate under the action of friction, and during the rotation of the pressing roller 405, the residue in the front position of the squeezing plate 4011 will be squeezed to disperse the residue in the water pipe, so as to avoid the residue from accumulating in the water pipe during the movement of the water pipe, thereby increasing the local space of the water pipe and increasing the squeezing of the squeezing plate 4011, which is convenient for the winding of the water pipe. At the same time, if the water pipe in front of the squeezing plate 4011 is blocked to a certain extent at this time, the water pipe will squeeze the squeezing plate 4011 to a certain extent, forcing the squeezing plate 4011 to move backward, and the piston cylinder 402 can provide a certain buffer space for the squeezing frame 401 as a whole, so as to avoid excessive squeezing between the water pipe and the squeezing frame 401, which causes damage to the water pipe. In this way, during the winding of the water pipe, the residue in the water pipe can be squeezed out, and at the same time, it helps to loosen the accumulation of residue in the water pipe, so as to avoid excessive accumulation of residue in the water pipe and affect the winding of the water pipe.

[0048] Specifically, four second sliding frames 406 are fixedly installed on the side of the fixed plate 4012 corresponding to the position of the rotating connecting plate 404 , the rotating connecting plate 404 is slidably installed on the second sliding frame 406 , and a spring is fixedly connected between the rotating connecting plate 404 and the second sliding frame 406 .

[0049] Specifically, a plurality of flexible rings 411 are evenly embedded and fixedly installed in the piston cylinder 402 , two first connecting tubes 408 are fixedly connected through the piston cylinder 402 , a piston plate 410 is fixedly connected to the end of the slide rod 409 , and a spring is fixedly connected between the piston plate 410 and the piston cylinder 402 .

[0050] Specifically, a first piston 407 is fixedly installed on the top of the rotating connecting plate 404 through a fixing ring, one end of the first connecting tube 408 is installed through the first piston 407 and the first connecting tube 408 connects the first piston 407 with the piston cylinder 402, and a piston rod of the first piston 407 is fixedly installed on the rotating connecting plate 404.

[0051] During the process of winding the water pipe, the residue in the water pipe is continuously squeezed out, and inevitably it will accumulate in the part of the water pipe that has not entered the squeezing plate 4011. When the residue accumulates too much and the pressing roller 405 cannot disperse the residue well by squeezing the residue, the accumulated residue will increase the diameter of the water pipe, so that when the water pipe contacts the squeezing plate 4011, a certain squeezing force will be generated on the squeezing plate 4011. This part of the squeezing force will be transmitted to the piston cylinder 402 through the sliding rod 409, and the air in the piston cylinder 402 will be transmitted to the first active In the plug 407, after the first piston 407 at the top is inflated, the piston rod of the first piston 407 will move downward to push the rotating connecting plate 404 downward. After the first piston 407 at the bottom is inflated, the piston rod of the first piston 407 will move downward to push the rotating connecting plate 404 upward. In this way, the pressing roller 405 at the top moves downward and the pressing roller 405 at the bottom moves upward, further squeezing the water pipe, increasing the pressure between the pressing roller 405 and the water pipe, and helping the pressing roller 405 to disperse the residue in the water pipe so that the residue at this position can be dispersed.

[0052] By adopting the piston cylinder 402 that provides a buffer, when too much residue accumulates in the water pipe and forces the extrusion frame 401 to move as a whole, the gas pressure generated during the movement can be transferred to the first piston 407, allowing the two pressing rollers 405 to move toward the water pipe, increasing the squeezing force on the water pipe, helping to disperse the residue in the water pipe, further helping to clean the residue in the water pipe, and reducing the residue in the water pipe.

[0053] During the movement of the slide bar 409, it will be hindered by the flexible ring 411, so that the slide bar 409 will present a jerky phenomenon in the sliding process of the piston cylinder 402. When it is transformed into a change of gas, the jerking of the slide bar 409 or the change of the conduction of the gas will be certain. Then, when the gas is transmitted to the first piston 407, the air pressure change curve in the first piston 407 is not constant. With the jerking of the slide bar 409, the air pressure is transmitted jerky, and the piston rod of the first piston 407 moves up or down jerky, so that the squeezing of the water pipe by the pressing roller 405 also changes jerky. This change can produce a changing squeezing effect on the water pipe during the movement of the water pipe, and avoid the pressing roller 405 from completely descending at one time, and the water pipe and the pressing roller 405 are in quick contact, and the residue is accumulated too much, and the pressing roller 405 cannot completely squeeze all the deposits. It can produce a more uniform squeezing effect on the accumulation of residues, and can better disperse the accumulation of residues.

[0054] Specifically, both ends of the rotating shaft of the pressing roller 405 are fixedly connected with gears 413 , and the gears 413 are located outside the rotating connecting plate 404 .

[0055] Specifically, the rotating connecting plate 404 is fixedly connected to a second piston 414 via a mounting frame, the second piston 414 is connected to the first piston 407 via a second connecting pipe 415, the piston rod of the second piston 414 is fixedly connected to a limiting protrusion 412, and the limiting protrusion 412 jams the gear 413 when it descends or ascends.

[0056] When the air pressure in the first piston 407 increases, part of the air pressure will be transferred to the second piston 414 through the conduction of the second connecting pipe 415. Similarly, after the second piston 414 at the top is inflated, the piston rod of the second piston 414 will move downward to push the limiting protrusion 412 downward. After the second piston 414 at the bottom is inflated, the piston rod of the second piston 414 will move downward to push the limiting protrusion 412 upward. The limiting protrusion 412 moving upward or downward will jam the gear 413, making the gear 413 unable to rotate, that is, making the pressing roller 405 unable to rotate, so that the pressing roller 405 squeezes the water pipe in a fixed manner. Compared with the pressing roller 405 rotating to squeeze the water pipe, the fixing of the pressing roller 405 can generate a greater squeezing force on the water pipe, so as to help better generate squeezing force on the accumulation of residues in the water pipe, help disperse the accumulation of residues, and achieve a better dispersion effect.

[0057] Specifically, the support bracket 3 is fixedly mounted on the base 1 , and the support bracket 3 is fixedly connected to the piston cylinder 402 .

[0058] Specifically, a plurality of electromagnets 302 are embedded and fixedly installed on the top of the support frame 3, and the upward magnetic poles of the electromagnets 302 are alternately distributed.

[0059] Specifically, an electromagnet 302 is embedded and fixedly installed at the bottom of the fixed plate 4012 at the bottom. When the fixed plate 4012 moves, the electromagnet 302 passes through the magnetic field range of the strong magnet 301. A first sliding frame 403 is fixedly installed on the rear side of the fixed plate 4012, and the end of the sliding rod 409 is slidably installed in the first sliding frame 403.

[0060] During the overall movement of the extrusion frame 401, the electromagnet 302 at the bottom of the extrusion plate 4011 is started, and the upward magnetic poles of the strong magnet 301 are alternately distributed. When the extrusion plate 4011 moves, the electromagnet 302 will be subjected to the alternating upward and downward magnetic field forces under the action of the magnetic field. Specifically, the strong magnet 301 generates a magnetic repulsion on the electromagnet 302, and the extrusion frame 401 is pushed upward as a whole. The next strong magnet 301 generates a magnetic attraction on the electromagnet 302, and the electromagnet 302 is magnetically attracted downward. In this way, during the overall forced movement of the extrusion plate 4011, the extrusion frame 401 will produce up and down fluctuations, and the water pipe will also produce up and down fluctuations, thereby causing the residue in the water pipe to produce a certain shaking under the shaking. Combined with the extrusion of the pressing roller 405, the extrusion of the residue in the water pipe can be better dispersed, thereby improving the effect of residue discharge, until the water pipe is completely rolled up, and the residue in the water pipe will be discharged from the end of the water pipe.

[0061] By alternating the upward magnetic poles of the strong magnets 301, when there is too much residue accumulated in the water pipe and the extrusion frame 401 is forced to move as a whole, the extrusion frame 401 as a whole will fluctuate up and down, causing the water pipe to shake up and down, helping the water pipe to contact the pressing roller 405. At the same time, the shaking water pipe can also help disperse the residue in the water pipe, further helping to clean the residue in the water pipe and reduce the residue in the water pipe.

[0062] Specifically, the winding wheel 2 includes two auxiliary iron wheels 201 and a winding drum 202 fixedly installed between the two auxiliary iron wheels 201, the winding drum 202 is provided with a clamping groove 205 for accommodating the end of the water pipe, the side wall of the clamping groove 205 is rotatably connected to a pressing plate 203 through a torsion spring, the bottom end of the pressing plate 203 is fixedly connected to an expansion air bag 206, both ends of the expansion air bag 206 are penetrated and fixedly connected to a fixed tube 207, the outer side of the auxiliary iron wheel 201 is fixedly connected to a sleeve 208, a movable disk 209 is slidably inserted in the sleeve 208, the side wall of the movable disk 209 is fixedly connected to an air guide tube 210, the two ends of the air guide tube 210 have holes on both sides, the air guide tube 210 corresponds to the fixed tube 207, and when the movable disk 209 slides into the sleeve 208, the air guide tube 210 is inserted into the fixed tube 207.

[0063] Specifically, the winding wheel 2 also includes two slides 212 fixedly mounted on the top of the base 1, through grooves are provided on both sides of the slide 212, an insertion rod 211 is slidably inserted in the slide 212, a spring is fixedly connected between the insertion rod 211 and the slide 212, a contact roller 214 is rotatably connected between the two insertion rods 211, the side wall of the slide 212 is fixedly connected to the limiting frame 204, the inner side wall of the limiting frame 204 is symmetrically and evenly provided with limiting teeth, a plurality of limiting frames 213 are movably inserted on the limiting frame 204, and both sides of the limiting frame 213 have symmetrically distributed frames, and inclined plane blocks 215 are elastically slidably inserted on both sides of the insertion rod 211 through springs, and the inclined planes of the inclined plane blocks 215 are distributed downward and correspond to the frames on the sides of the limiting frames 213.

[0064] Before placing the end of the water pipe on the winding drum 202, it is necessary to lift the pressing sheet 203 upwards, place the end of the water pipe on the clamping groove 205, and then put down the pressing sheet 203. Using the elastic force of the torsion spring on the pressing sheet 203, the end of the water pipe is clamped between the expansion airbag 206 and the clamping groove 205, and then push the moving plate 209 until the moving plate 209 is adsorbed on the auxiliary iron wheel 201, and the gas in the moving plate 209 enters through the hole of the air guide tube 210 close to the port of the moving plate 209, and exits from the port of the air guide tube 210 away from the moving plate 209. As the moving plate 209 moves, the air guide tube 210 will be inserted into the fixed tube 207 on the expansion airbag 206 and fixed. The expansion airbag 206 and the fixed tube 207 are positioned, and at the same time, the gas will enter the expansion airbag 206 through the air guide tube 210, causing the expansion airbag 206 to expand. The expanded expansion airbag 206 will generate a greater downward pressure on the end of the water pipe. At the same time, since the fixed tube 207 is inserted into the air guide tube 210, the expansion of the expansion airbag 206 cannot act upward on the pressing sheet 203, but can only act downward on the end of the water pipe, so that the end of the water pipe can be firmly pressed between the pressing sheet 203 and the clamping groove 205, which has an effective fixing effect, helping the end of the water pipe not to slide when the water pipe is rolled up, thereby helping the water pipe to remain taut in the initial stage of rolling up.

[0065] When the auxiliary iron wheel 201 rotates to reel in the water pipe, as the water pipe is gradually reeled in, the thickness of the water pipe in the radial direction gradually increases. At the same time, the contact roller 214 is close to the outer side of the water pipe, which suppresses the water pipe, so that during the reeling process, the wrinkled part of the water pipe is blocked by the contact roller 214 outside the reeled range of the water pipe, that is, it is difficult for the water pipe to wrinkle when it is reeled in. At the same time, as the thickness of the water pipe in the radial direction gradually increases, the pressure on the contact roller 214 will gradually increase during this process, and the insertion rod 2 The spring between the slide 211 and the slide 212 will shrink, and the plunger 211 will drop to a certain position. When the plunger 211 drops, the inclined surface block 215 will contact the two side frames of the limit frame 213 on the slide 212 and shrink inward. For each additional circle of the water pipe, that is, the thickness of the water pipe in the radial direction will increase by twice the thickness of the water pipe wall. After the inclined surface block 215 passes through the two side frames of the limit frame 213, it will extend out again under the action of the spring between the inclined surface block 215 and the plunger 211. The straight wall makes the inclined block 215 stuck at the top of the frame on both sides of the limit frame 213, that is, each time a circle of water pipe is added, the insertion rod 211 is lowered by one grid under the action of the inclined block 215, so that each circle of water pipe added will be squeezed by a fixed height or water pipe thickness, ensuring that when the water pipe wrinkles are generated, the contact roller 214 will not continue to move downward under the elastic support, so that the wrinkles of the water pipe can smoothly pass through the space between the winding drum 202 and the contact roller 214, so that the water pipe can be more tightly pressed. At the same time, the spacing between each limit frame 213 can be adjusted according to the wall thickness of the water pipe. For example, when the water pipe is thicker, the thickness of the water pipe will increase by adding a circle. At this time, the spacing between the limit frames 213 can be increased, so that after the inclined plane block 215 descends, the height is limited by the limit frames 213 with larger intervals. In this way, the descending height of the inclined plane block 215 each time matches the thickness of the water pipe, which can help adapt to the winding work of water pipes of thicker thicknesses and reduce the wrinkles caused by the winding of the water pipe.

[0066] It should be noted that in order to clearly show the limit frames 213 and the limit frames 204 in the accompanying drawings, they are larger in proportion, wider in spacing, and fewer in number. In order to accommodate the winding of the water pipe, the overall length of the slide 212 should be longer, and the number of the limit frames 213 should be greater. These are foreseeable based on the accompanying drawings and the specification. Therefore, the height of the slide 212 and the number of the limit frames 213 in the accompanying drawings should not be used as factors that limit the number of water pipe winding turns in the solution.
