Description

Technical Field

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

[0002] Integrated water-fertilizer technology is a water-saving agricultural technique that utilizes irrigation systems and specialized fertilization equipment to achieve simultaneous management and efficient utilization of water and fertilizer. Water-soluble fertilizers on the market are categorized into two types: solid water-soluble fertilizers (powders or granules) and liquid water-soluble fertilizers (clear liquids, fluid fertilizers, and highly concentrated suspended fluid fertilizers). Liquid water-soluble fertilizers are more expensive, so solid water-soluble fertilizers are generally used. Solid water-soluble fertilizers require manual premixing of solid waste with water.

[0003] When adding water to existing solid fertilizers, the solid fertilizer and the required amount of water are typically poured into a mixing bucket and stirred. However, due to the excessive amount of water and solid fertilizer, the stirring power required is high and the stirring time is long to achieve a thorough mixing. If the stirring power is low and the stirring time is short, the fertilizer dissolution rate is slow and the dissolution effect is poor, which reduces the efficiency and effectiveness of farmland irrigation.

[0035] Example:

[0036] Reference Figure 1 、 Figure 2 and Figure 3 , a water-fertilizer integrated irrigation system, comprising a mobile base 1, and further comprising:

[0037] Fertilizer box 2, which is fixed on the mobile base 1 and is used to store solid water-soluble fertilizer. The bottom of the fertilizer box 2 is connected to a water outlet pipe 201;

[0038] A mixing barrel 3 is provided on the fertilizer box 2, and the bottom opening of the mixing barrel 3 is communicated with the top of the fertilizer box 2. A first plugging component for plugging the bottom opening of the mixing barrel 3 is provided in the fertilizer box 2;

[0039] The feeding part 4 is provided on the mobile base 1 and is used to transport solid fertilizer and water into the mixing barrel 3. The mixing barrel 3 is provided with a second blocking component for blocking the discharge end of the feeding part 4; and

[0040] The limiting mechanism is connected to the first blocking component and the second blocking component.

[0041] Specifically, the staff can first mix a small amount of fertilizer with water to prepare a water-fertilizer solution without the need for long stirring time and large stirring power, and place the mixed water-fertilizer solution in the fertilizer box 2. The first limit component automatically blocks the opening at the bottom of the mixing barrel 3, and then the feeding part 4 pours the fertilizer and water into the mixing barrel 3. When the water in the mixing barrel 3 reaches a certain height, the second blocking component blocks the discharge end of the feeding part 4, limiting the fertilizer and water from continuing to be poured into the mixing barrel 3, so that the mixing barrel 3 mixes the appropriate amount of water and fertilizer. During this process, the staff can fertilize the farmland through the external irrigation water pipe through the outlet pipe 201, and can use the mixing barrel 3 to stir and mix part of the fertilizer and water during the fertilization process, so as to achieve simultaneous mixing and fertilization. There is no need to wait until all the fertilizers and water are mixed before irrigation operations are performed, thereby ensuring the stirring efficiency and stirring effect of the water-fertilizer solution and improving the irrigation efficiency and irrigation effect of the staff.

[0042] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4As a preferred technical solution of the present invention, the feeding part 4 includes a support plate 401 fixedly mounted on the mobile base 1, a water tank 402 is provided on the support plate 401, a first feed pipe 4021 is provided between the water tank 402 and the mixing barrel 3, and the feeding part 4 also includes a second feed pipe 4031 arranged on the upper side of the mixing barrel 3, and a hopper 403 is provided at one end of the second feed pipe 4031 away from the mixing barrel 3, and the second feed pipe 4031 is placed on the upper side of the first feed pipe 4021; specifically, the water tank 402 is filled with clean water, and fertilizer is poured into the hopper 403, and the openings of the hopper 403 and the water tank 402 are adjusted so that the fertilizer and clean water enter the mixing barrel 3 in equal proportions, and the second feed pipe 4031 for conveying fertilizer is placed on the upper side of the first feed pipe 4021 for conveying clean water, so that the falling fertilizer can be preliminarily and evenly mixed with the flowing water, thereby avoiding the accumulation of fertilizer in one place in the water body, which affects the stirring and mixing rate and mixing effect of the solution in the subsequent mixing barrel 3.

[0043] Reference Figure 1 、 Figure 2 and Figure 3 As a preferred technical solution of the present invention, a stirring motor 301 is provided on the top of the mixing barrel 3. The output end of the stirring motor 301 passes through the mixing barrel 3 and is connected to a stirring shaft 302. The stirring shaft 302 is rotatably connected in the mixing barrel 3. Evenly distributed stirring blades 303 are provided on the outside of the stirring shaft 302. Specifically, the stirring motor 301 is controlled to operate so that the output end of the stirring motor 301 drives the stirring shaft 302 to rotate, and the stirring shaft 302 drives the stirring blades 303 to stir and mix the water and fertilizer in the mixing barrel 3.

[0044] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As a preferred technical solution of the present invention, the second blocking assembly includes a fixed rod 304 fixed in the mixing barrel 3, a blocking plate 5 for blocking the openings of the first material pipe 4021 and the second material pipe 4031 is slidably connected to the outside of the fixed rod 304, a first elastic element 3041 is sleeved on the outside of the fixed rod 304, and the two ends of the first elastic element 3041 are respectively connected to the inner wall of the mixing barrel 3 and the blocking plate 5, and a floating ring 6 is provided on the end of the blocking plate 5 away from the first elastic element 3041; specifically, the feed part 4 is directed to the mixing barrel 3. When water and fertilizer are transported in the mixing barrel 3, the floating ring 6 rises as the water level rises. The floating ring 6 drives the blocking plate 5 to move upward and squeeze the first elastic element 3041. When the water in the mixing barrel 3 reaches a certain height, the floating ring 6 drives the blocking plate 5 to block the openings of the first material pipe 4021 and the second material pipe 4031, preventing further entry of materials into the mixing barrel 3. The mixing barrel 3 can stir and mix a small amount of water and fertilizer without excessive stirring driving force, and the water and fertilizer can be quickly and fully mixed, with a good mixing effect.

[0045] Reference Figure 3 、 Figure 6 and Figure 7 As a preferred technical solution of the present invention, the first blocking component includes a guide rod 7 fixedly arranged in the fertilizer box 2, a first floating block 701 is slidably connected to the outside of the guide rod 7, a second elastic element 702 is provided between the first floating block 701 and the inner wall of the fertilizer box 2, a connecting pipe 703 is provided on the side of the first floating block 701 away from the second elastic element 702, and a blocking block 704 for blocking the bottom opening of the mixing barrel 3 is provided on the top of the connecting pipe 703; specifically, when there is a certain amount of water-fertilizer solution in the fertilizer box 2, the first floating block 701 is subjected to buoyancy and moves upward on the outside of the guide rod 7, and the second elastic element 702 is When the mixing barrel 3 is stretched, the first floating block 701 drives the connecting pipe 703 and the blocking block 704 to move upward, so that the blocking block 704 blocks the opening at the bottom of the mixing barrel 3, thereby preventing the water-fertilizer solution in the mixing barrel 3 from being fully mixed into the fertilizer box 2 and affecting the fertilization effect of the subsequent water-fertilizer solution. It should be noted that the buoyancy of the first floating block 701 is greater than the downward pressure of the liquid in the mixing barrel 3 on the blocking block 704. The inner wall of the bottom of the mixing barrel 3 can also be set horizontally, so that the blocking block 704 at the bottom opening of the mixing barrel 3 will only be affected by the gravity of a small part of the liquid, and the buoyancy of the first floating block 701 can completely overcome the downward pressure of the gravity of this part of the liquid.

[0046] Reference Figure 3 、 Figure 6 and Figure 7As a preferred technical solution of the present invention, the limiting mechanism includes a fixed block 202 fixedly mounted on the inner wall of the fertilizer box 2, a first groove 8 is provided on the fixed block 202, a first limiting block 801 is slidably connected in the first groove 8 and movably opposed to the first floating block 701, a third elastic element 802 is provided between the first limiting block 801 and the inner wall of the first groove 8, and a first limiting groove 7011 is provided on the first floating block 701 to cooperate with the first limiting block 801; specifically, after the water and fertilizer in the fertilizer box 2 is about to be used up, the first floating block 701 is no longer subjected to buoyancy and moves downward under the elastic force of the second elastic element 702. During this process, the first limiting block 801 avoids the first floating block 701, and the third elastic element 802 is squeezed. When the first limiting block 801 is moved away from the first floating block 701, the third elastic element 802 is squeezed. After the limiting groove 7011 corresponds to the position of the first limiting block 801, the first limiting block 801 is reset and inserted into the first limiting groove 7011 under the elastic force of the third elastic element 802, limiting the position of the first floating block 701. After the blocking block 704 no longer blocks the opening at the bottom of the mixing barrel 3, the mixed water and fertilizer solution in the mixing barrel 3 enters the fertilizer box 2 from the bottom opening of the mixing barrel 3. Since the first floating block 701 is restricted and positioned, the water and fertilizer solution in the mixing barrel 3 can be completely poured into the fertilizer box 2, avoiding the first floating block 701 from being unrestricted. As the water and fertilizer level in the fertilizer box 2 increases, the first floating block 701 drives the blocking block 704 to re-block the bottom of the mixing barrel 3 in real time, resulting in the water and fertilizer solution in the mixing barrel 3 being unable to be effectively poured out.

[0047] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As a preferred technical solution of the present invention, the limiting mechanism includes a second groove 9 provided on the mixing barrel 3, a second limiting block 901 movably abutting against the blocking plate 5 is slidably connected in the second groove 9, a fourth elastic element 902 is provided between the second limiting block 901 and the inner wall of the second groove 9, and a second limiting groove 903 is provided on the blocking plate 5 to cooperate with the second limiting block 901; specifically, when the feeding part 4 transports water and fertilizer into the mixing barrel 3, the floating ring 6 drives the blocking plate 5 Move upward and block the openings of the first material pipe 4021 and the second material pipe 4031. During this process, the second limit block 901 avoids the blocking plate 5 that is moving upward, and the fourth elastic element 902 is compressed. When the blocking plate 5 blocks the feed part 4, the second limit groove 903 matches the position of the second limit block 901. The second limit block 901 is reset and inserted into the second limit groove 903 under the elastic force of the fourth elastic element 902, maintaining the blocking state of the blocking plate 5 on the feed part 4.

[0048] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As a preferred technical solution of the present invention, a support plate 10 is fixedly provided on the fertilizer box 2, and a rotating rod 11 is rotatably connected to the support plate 10. Two take-up rollers 111 are provided on the rotating rod 11, and each take-up roller 111 is provided with a pull rope 112, one end of the pull rope 112 away from the take-up roller 111 is connected to the first limit block 801, and the other end of the pull rope 112 away from the take-up roller 111 is connected to the second limit block 901. A driven gear 113 is also provided on the rotating rod 11, and a rack plate 12 meshing with the driven gear 113 is slidably connected to the fertilizer box 2, and a fifth elastic element 121 is provided between the rack plate 12 and the inner wall of the fertilizer box 2.

[0049] Furthermore, a second floating block 13 is slidably connected to the outer side of the connecting pipe 703 , and a side plate 131 is connected to the second floating block 13 . The side plate 131 and the rack plate 12 are movably opposed to each other.

[0050] Specifically, when the water-fertilizer solution is discharged from the mixing barrel 3, the second float 13 in the fertilizer box 2 rises as the liquid level rises. When the evenly mixed water-fertilizer solution in the mixing barrel 3 is poured into the fertilizer box 2, the liquid level in the fertilizer box 2 reaches the specified position. At this time, the second float 13 drives the side plate 131 to push up the bottom of the rack plate 12, so that the rack plate 12 engages with the driven gear 113 on the rotating rod 11 for transmission. The driven gear 113 drives the rotating rod 11 to rotate, and the take-up roller 111 on the rotating rod 11 rewinds the pull rope 112, thereby causing the first limit block 801 to retract into the first groove 8, and the second limit block 901 When the mixing barrel 3 is filled with water, the first floating block 701 in the fertilizer box 2 is no longer restricted and moves upward rapidly under the action of its own buoyancy, so that the blocking block 704 blocks the opening at the bottom of the mixing barrel 3, and the blocking plate 5 is no longer restricted by the second limit block 901 and is reset and moved downward under the elastic force of the first elastic element 3041, so that the feeding part 4 continues to transport fertilizer and clean water into the mixing barrel 3. The staff can continue to fertilize with the water-fertilizer solution in the fertilizer box 2, and the mixing barrel 3 mixes the fertilizer during the fertilization process, which ensures the stirring efficiency and stirring effect of the water-fertilizer solution and improves the irrigation efficiency and irrigation effect of the staff.

[0051] Reference Figure 1 and Figure 2 As a preferred technical solution of the present invention, the tops of the fertilizer box 2 and the water tank 402 are both provided with a liquid injection port 14; specifically, it is convenient to add solution or clean water into the fertilizer box 2 and the water tank 402.

[0052] Working principle: The staff can first mix a small amount of fertilizer with water to prepare a water-fertilizer solution without stirring for a long time or with a large stirring force, and then place the mixed water-fertilizer solution into the fertilizer box 2 through the liquid injection port 14; when there is a certain amount of water-fertilizer solution in the fertilizer box 2, the first floating block 701 is buoyant and moves upward on the outside of the guide rod 7, the second elastic element 702 is stretched, and the first floating block 701 drives the connecting pipe 703 and the blocking block 704 to move upward, so that the blocking block 704 blocks the opening at the bottom of the mixing barrel 3, thereby preventing the water and fertilizer in the mixing barrel 3 from being fully mixed. The solution enters the fertilizer box 2, and the water level of the water-fertilizer solution is higher than the first float 701; the staff can fertilize the farmland through the external irrigation water pipe through the outlet pipe 201. In this process, the feeding part 4 pours fertilizer and water into the mixing barrel 3 in equal proportion. When the water in the mixing barrel 3 reaches a certain height, the floating ring 6 rises with the increase of the water height, and the floating ring 6 drives the blocking plate 5 to move up and squeeze the first elastic element 3041. When the water in the mixing barrel 3 reaches a certain height, the floating ring 6 drives the blocking plate 5 to move up and squeeze the first elastic element 3041. The opening of the tube 4031 is blocked, and the second limiting block 901 is inserted into the second limiting groove 903 to maintain the blocking state of the blocking plate 5 on the feeding part 4; the output end of the stirring motor 301 drives the stirring shaft 302 to rotate, and the stirring shaft 302 drives the stirring blade 303 to stir and mix the water and fertilizer in the mixing barrel 3; after the water and fertilizer in the fertilizer box 2 are about to be used up, the first floating block 701 is no longer subject to buoyancy and moves downward under the elastic force of the second elastic element 702. During this process, the first limiting block 801 avoids the first floating block 701, and the third elastic element When the first limiting groove 7011 corresponds to the first limiting block 801, the first limiting block 801 is reset under the elastic force of the third elastic element 802 and inserted into the first limiting groove 7011, restricting the position of the first floating block 701. After the blocking block 704 no longer blocks the opening at the bottom of the mixing barrel 3, the mixed water-fertilizer solution in the mixing barrel 3 flows into the fertilizer box 2 from the bottom opening of the mixing barrel 3. Since the first floating block 701 is restricted in position, the water-fertilizer solution in the mixing barrel 3 can be completely poured into the fertilizer box 2.When the water-fertilizer solution is discharged from the mixing barrel 3, the second float 13 in the fertilizer box 2 rises as the liquid level rises. When the evenly mixed water-fertilizer solution in the mixing barrel 3 is poured into the fertilizer box 2, the liquid level in the fertilizer box 2 reaches the specified position. At this time, the second float 13 drives the side plate 131 to push up the bottom of the rack plate 12, so that the rack plate 12 engages with the driven gear 113 on the rotating rod 11 for transmission. The driven gear 113 drives the rotating rod 11 to rotate, and the take-up roller 111 on the rotating rod 11 rewinds the pull rope 112, thereby causing the first limit block 801 to retract into the first groove 8, and the second limit block 901 to retract into the first groove 8. Within the second groove 9, the first floating block 701 in the fertilizer bin 2 is no longer restricted and rapidly moves upward under its own buoyancy, thereby allowing the blocking block 704 to seal the bottom opening of the mixing barrel 3. The blocking plate 5, no longer restricted by the second limit block 901, returns to its original position and moves downward under the elastic force of the first elastic element 3041, allowing the feed portion 4 to continue to deliver fertilizer and water into the mixing barrel 3. The worker can continue to fertilize using the water-fertilizer solution in the fertilizer bin 2, and the mixing barrel 3 mixes the fertilizer during the fertilization process, ensuring the stirring efficiency and effect of the water-fertilizer solution, thereby improving the worker's irrigation efficiency and effect.
