Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sprinkling irrigation devices, and particularly relates to a liquid fertilizer sprinkling irrigation device for alfalfa planting. BACKGROUND

[0002] Alfalfa is a perennial herbaceous plant of the Leguminosae and Medicago genus. The stem is erect, clumped or creeping, tetrahedral, and mostly branched. The stipules are large and ovate-lanceolate, and the leaflets are obcordate-oblong. The flowers are in clustered racemes, and the flower stems are bell-shaped. The corolla is purple. The fruit is spiral, and is brown when ripe. The seeds are small and smooth, and are yellow or brown. In the planting process, irrigation and fertilization are needed to stabilize the yield and ensure the normal growth of alfalfa.

[0003] However, the existing sprinkling irrigation technology still has the following deficiencies in application:

[0004] (1) In the existing technology, the function is single during fertilization, and only fertilization operation can be achieved. When the alfalfa leaves turn yellow and the edges are scorched, it indicates that the fertilizer concentration is too high or the electrical conductivity (EC) value exceeds the standard, and irrigation needs to be stopped immediately and the soil needs to be flushed with irrigation water (because it is in the wild, the irrigation water used is mostly river water / lake water / collection of rainwater / irrigation canal water). However, the existing sprinkling irrigation equipment needs to be switched to the irrigation water mode or another flushing device needs to be provided, which not only increases the planting cost, but also cannot adjust the fertilization and irrigation strategy in time according to the growth of alfalfa;

[0005] (2) When liquid fertilizer irrigation is performed, sedimentation easily occurs in the liquid fertilizer, which causes the fertilizer to be unable to be absorbed by the alfalfa during the irrigation process, and the sedimentation easily blocks the sprinkler. In addition, whether it is liquid fertilizer or irrigation water, the sedimentation in the storage cylinder is accumulated for a long time, and the metal ions such as iron and manganese in the sedimentation may form acidic substances after oxidation, accelerate the corrosion of the metal of the tank body, and affect the service life of the equipment.

DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0054] Embodiment 1

[0055] Referring to Figure 1 and Figure 2 , the sprinkling device relates to the technical field of sprinkling devices, and comprises a mobile frame 1. The bottom of the mobile frame 1 is rotationally connected to two first rotating shafts 2 through a base. The two ends of the two first rotating shafts 2 are both fixed with anti-skid wheels 3 through bolts.

[0056] When moving, the first rotating shafts 2 rotate in the base to drive the anti-skid wheels 3 to rotate, so that the mobile frame 1 as a whole can stably move by utilizing the friction between the anti-skid wheels 3 and the ground, thereby facilitating the irrigation and fertilization operation of alfalfa in different planting areas.

[0057] Referring to Figure 1 and Figure 2 , the device further comprises a storage tank 4 fixed on the top of the mobile frame 1 through bolts. The mobile frame 1 is fixed with a partition 5. The storage tank 4 forms a liquid fertilizer bin 7 and a water bin 8 through the partition 5, and is respectively used for storing liquid fertilizer and irrigation water.

[0058] Referring to Figure 1 , Figure 6 and Figure 7An unfolding structure is provided at one end of the storage tank 4. The unfolding structure includes two connecting arms 35 rotating at one end of the movable frame 1 and a second electric push rod 42 fixed to the top of the storage tank 4. The unfolding structure also includes two second rotating shafts 33 rotating at one end of the storage tank 4 via a base plate 21. Connecting seats 34 are fixedly sleeved on the outer walls of the two second rotating shafts 33. The two connecting seats 34 are rotatably connected to the two connecting arms 35 on opposite sides. Irrigation pipes 37 are fixedly connected to the bottom of the two connecting arms 35 via U-shaped brackets. Multiple nozzles 38 are fixed to the bottom of the irrigation pipes 37. Cams 39 are fixed to the top of the two second rotating shafts 33 by bolts. Pins 40 are fixed to the top of the two cams 39 by bolts. The output shaft of the second electric push rod 42 is fixed to a movable frame 41. The two pins 40 slide within the movable frame 41. Support blocks 43 are welded to both sides of the storage tank 4.

[0059] Specifically, when irrigation is needed, the second electric push rod 42 is activated, and its output shaft retracts to move the moving frame 41. Since the pin 40 slides within the moving frame 41, the movement of the moving frame 41 causes the cam 39 and the second rotating shaft 33 to rotate. The second rotating shaft 33 drives the connecting arm 35 to rotate via the connecting seat 34, thus unfolding the connecting arm 35. After unfolding, the multiple nozzles 38 at the bottom of the two irrigation pipes 37 can perform irrigation. Simultaneously, a self-locking motor 36 is fixed within the connecting seat 34. The output shaft of the self-locking motor 36 is fixedly connected to the connecting arm 35. By driving the connecting arm 35 to rotate via the self-locking motor 36, the connecting arm 35 can be tilted, allowing fertilization of the alfalfa planted on the gentle slope. When irrigation is not needed, the output shaft of the second electric push rod 42 extends, pushing the moving frame 41 to move in the opposite direction, causing the connecting arm 35 to rotate and fold. The support block 43 supports the folded connecting arm 35.

[0060] Reference Figure 7 Based on the above-mentioned device, a self-locking motor 36 is fixedly installed in the connecting seat 34 by bolts, and the output shaft of the self-locking motor 36 is fixedly connected to the connecting arm 35 by a coupling.

[0061] Specifically, when it is necessary to irrigate the alfalfa planted on the slope, the connecting arm 35 is extended, and then the self-locking motor 36 is started. The output shaft of the self-locking motor 36 drives the connecting arm 35 to rotate, causing the connecting arm 35 to be placed at an angle. By controlling the rotation angle of the self-locking motor 36, the tilt angle of the connecting arm 35 can be precisely adjusted to adapt to slopes of different gradients, ensuring that the irrigation pipe 37 can accurately irrigate the alfalfa on the slope.

[0062] Reference Figure 2 and Figure 3The replacement structure comprises a trapezoidal rod 27 slidingly connected in the partition plate 5 and a sealing plate 13 sliding in the moving frame 1, and further comprises a liquid discharge tank 11 fixed in the moving frame 1, and a liquid fertilizer bin 7 and a water bin 8, the inner walls of the bottoms of which are fixedly penetrated by liquid discharge pipes 12, the bottom ends of the two liquid discharge pipes 12 are fixedly extended into the liquid discharge tank 11, and the sealing plate 13 is sealingly and slidingly connected to the top inner wall of the liquid discharge tank 11 and used for closing and opening the liquid discharge pipes 12. A first electric push rod 14 is fixed in the moving frame 1, one end of the output shaft of the first electric push rod 14 is sealingly and slidingly extended into the liquid discharge tank 11 and fixedly connected to one side of the sealing plate 13 and used for driving the sealing plate 13 to move. The inner walls of the sides, away from each other, of the liquid fertilizer bin 7 and the water bin 8 are rotationally connected with stirring shafts 17, and the outer walls of the two stirring shafts 17 are fixedly provided with a plurality of stirring blades 18.

[0063] Specifically, when irrigation water irrigation is needed, the first electric push rod 14 is started, the output shaft of the first electric push rod 14 pushes the sealing plate 13 to move to the left side, the liquid discharge pipes 12 below the liquid fertilizer bin 7 are closed, and the irrigation water in the water bin 8 enters the liquid discharge tank 11 through the corresponding liquid discharge pipes 12. When liquid fertilizer irrigation is needed, the output shaft of the first electric push rod 14 pushes the sealing plate 13 to move to the right side, the liquid discharge pipes 12 below the water bin 8 are closed, and the liquid fertilizer in the liquid fertilizer bin 7 enters the liquid discharge tank 11 through the corresponding liquid discharge pipes 12. During the liquid discharge process, the stirring shafts 17 and the stirring blades 18 continuously rotate to stir the liquid in the liquid fertilizer bin 7 and the water bin 8, so as to prevent the liquid from precipitating.

[0064] With reference to Figure 2 - Figure 5 The control structure is used for controlling the liquid in the liquid fertilizer bin 7 and the water bin 8 to enter the liquid discharge tank 11 according to the needs, and cooperating with the water pump 16 and other devices to deliver the liquid to the irrigation pipe 37. The driving structure provides power for the rotation of the stirring shafts 17 and the stirring blades 18, so as to ensure that the liquid in the liquid fertilizer bin 7 and the water bin 8 can be fully stirred while the corresponding liquid irrigation is completed, the liquid fertilizer and the irrigation water are uniformly mixed, and the irrigation effect is improved. Through the cooperative work of the control structure and the driving structure, the type and amount of the liquid for irrigation can be accurately controlled according to the growth of alfalfa, so as to realize the precise fertilization and irrigation of alfalfa.

[0065] With reference to Figure 3 and Figure 4The control structure comprises a cylinder 6 fixed in the partition plate 5, the inner wall of the top of the cylinder 6 is fixedly provided with a base plate 21 through bolts, and the base plate 21 is rotatably connected with a first bevel gear 22 on one side. The first bevel gear 22 is slidably penetrated by a transmission shaft 23 through a sliding groove and a sliding block. The bottom inner wall of the cylinder 6 is slidably connected with a frame body 26, and one end of the transmission shaft 23 is fixedly penetrated through the frame body 26. The transmission shaft 23 is fixed with a first transmission mechanism at both ends. The two stirring shafts 17 are rotatably extended into the cylinder 6 at one end close to each other and are fixed with a second transmission mechanism. The adjacent first transmission mechanism and the second transmission mechanism are in transmission connection, and are used for driving the corresponding stirring shaft 17 to rotate. The trapezoidal rod 27 is sealingly and slidably extended into the cylinder 6 at the top end and is installed with a spring 29 through a spring seat. The top end of the spring 29 abuts against the bottom of the frame body 26 through a spring seat, and is used for resetting the trapezoidal rod 27 to move downward. The bottom of the frame body 26 and the top of the trapezoidal rod 27 are rotatably connected through a connecting rod 28, and are used for driving the frame body 26 to move when the trapezoidal rod 27 is lifted. The top of the sealing plate 13 is provided with a trapezoidal groove 30, and the bottom end of the trapezoidal rod 27 is sealingly and slidably extended into the liquid tank 11 and matched with the trapezoidal groove 30. When the sealing plate 13 moves, the trapezoidal rod 27 is driven to lift through the cooperation between the trapezoidal groove 30 and the trapezoidal rod 27.

[0066] Specifically, when the trapezoidal rod 27 moves downward under the elastic force of the spring 29, the trapezoidal rod 27 drives the frame body 26 and the transmission shaft 23 to move to the left side through the connecting rod 28. The second rotating disc 24 located on the left side corresponds to the adjacent first rotating disc 19. At this time, the magnetic attraction force between the adjacent first magnet 20 and the second magnet 25 drives the stirring shaft 17 and the stirring blade 18 to rotate, stirs the liquid fertilizer in the liquid fertilizer bin 7, and re-dissolves the precipitate in the liquid to avoid the precipitation. Conversely, the stirring shaft 17 in the water bin 8 can be driven to rotate to stir the irrigation water.

[0067] With reference to Figure 4 The first transmission mechanism comprises the second rotating disc 24 and a plurality of second magnets 25. The second rotating disc 24 is fixed at the end of the transmission shaft 23, and the plurality of second magnets 25 are fixed at one end of the second rotating disc 24 away from the transmission shaft 23 and are arranged in a ring shape. The second transmission mechanism comprises the first rotating disc 19 and a plurality of first magnets 20. The first rotating disc 19 is fixed at one end of the stirring shaft 17 close to the transmission shaft 23, and the plurality of first magnets 20 are fixed at one side of the first rotating disc 19 close to the transmission shaft 23 and are arranged in a ring shape. The first magnet 20 and the second magnet 25 generate magnetic attraction force.

[0068] Specifically, the two first transmission mechanisms are driven to move through the transmission shaft 23, the distance between the adjacent first transmission mechanism and the second transmission mechanism is controlled, and the corresponding stirring shaft 17 is driven to rotate through the transmission shaft 23, so as to complete the stirring of the corresponding liquid.

[0069] With reference to Figure 4 and Figure 5The driving structure comprises a second bevel gear 32 rotating in the cylinder 6, and the second bevel gear 32 is engaged with the first bevel gear 22. The driving shaft 31 is fixed at one side of the second bevel gear 32, and the driving shaft 31 is rotatably penetrated through the cylinder 6, the partition plate 5 and the storage tank 4 in sequence and is fixed with a first synchronous wheel. The outer wall of one of the first rotating shafts 2 is fixed with a second synchronous wheel, and the first synchronous wheel and the second synchronous wheel are connected through a synchronous belt transmission for driving the second bevel gear 32 to rotate when the first rotating shaft 2 rotates, thereby providing driving force for the control structure.

[0070] Through the cooperative work of the above parts, the alfalfa planting liquid fertilizer sprinkling irrigation device can realize efficient and accurate irrigation and fertilization of alfalfa, and at the same time, it is convenient for the staff to adjust the irrigation strategy according to the growth of alfalfa.

[0071] With reference to Figure 2 , Figure 3 and Figure 6 , one end of the storage tank 4 is fixedly installed with a water pump 16 through bolts. The liquid inlet end of the water pump 16 is fixedly connected with a liquid inlet pipe 15 through a flange, one end of the liquid inlet pipe 15 extends into the liquid discharge tank 11 and is sealingly connected with the liquid discharge tank 11 to ensure that the liquid does not leak. The liquid outlet end of the water pump 16 is fixed with a three-way valve, and the three-way valve is connected with two irrigation pipes 37 through hoses respectively.

[0072] Specifically, the water pump 16 is started, and the liquid fertilizer in the liquid discharge tank 11 enters the water pump 16 through the liquid inlet pipe 15 under the action of negative pressure, and then is distributed to the two irrigation pipes 37 through the three-way valve, thereby providing corresponding liquid for the irrigation pipes 37 and realizing the functions of extraction and irrigation of the liquid fertilizer.

[0073] With reference to Figure 2 , the top of the storage tank 4 is rotatably provided with a column 9 through a bearing, and the top of the column 9 is fixedly provided with a high-definition camera 10 through bolts.

[0074] The high-definition camera 10 can capture the alfalfa planting situation in real time, and the captured images or videos can be transmitted to the control terminal through wired or wireless mode, and these data provide basis for the staff to judge the water supplement or fertilization in the later stage, and then adjust the parameters such as the type, concentration and irrigation amount of the liquid fertilizer, so as to realize accurate irrigation of alfalfa and stabilize the yield of alfalfa.

[0075] Through the cooperative work of the above parts, the alfalfa planting liquid fertilizer sprinkling irrigation device can realize efficient and accurate irrigation and fertilization of alfalfa, and at the same time, it is convenient for the staff to adjust the irrigation strategy according to the growth of alfalfa.

[0076] Example 2

[0077] With reference to Figure 8 - Figure 10On the basis of Embodiment 1, the two sides of the partition plate 5 are slidably connected with floating plates 44 through sliding rails, and the floating plates 44 are matched with adjacent stirring blades 18. When the stirring shaft 17 and the stirring blades 18 rotate to stir the liquid fertilizer in the liquid fertilizer bin 7, the thrust of the stirring blades 18 and the floating force of the floating plates 44 under the action of the liquid fertilizer drive the floating plates 44 to reciprocatingly move up and down. The top of each of the two floating plates 44 is fixed with two lifting rods 45 through bolts, and the top of each of the two lifting rods 45 slidably extends to above the storage tank 4. Adjacent two lifting rods 45 are fixed with connecting plates 46 through bolts, and the two connecting plates 46 are located on the two sides of the column 9. The side of each of the two connecting plates 46 close to each other is fixed with a pin block 47 through a bolt, and the outer wall of the column 9 is provided with two arc-shaped grooves 48 matched with the pin blocks 47.

[0078] Specifically, when the stirring blades 18 rotate to drive the floating plates 44 and the lifting rods 45 to reciprocatingly move up and down, the lifting rods 45 drive the connecting plates 46 and the pin blocks 47 to synchronously move. When the pin blocks 47 move in the arc-shaped grooves 48, the column 9 is driven to reciprocatingly rotate. With the advancing of the mobile frame 1 for irrigation and fertilization, the high-definition camera 10 can shoot a wider alfalfa planting area under the reciprocating rotation of the column 9, so that the staff can more comprehensively understand the growth of the alfalfa and provide more accurate basis for subsequent irrigation and fertilization.

[0079] A method for using the alfalfa planting liquid fertilizer sprinkling irrigation device, comprising the following steps:
