Description

Technical Field

[0001] The invention relates to the technical field of irrigation, and in particular to automatic fertilizer and water irrigation equipment. Background Art

[0002] When irrigating with fertilizer water, since the nitrogen content in the fertilizer water is high, it is necessary to dilute the fertilizer water before irrigating with fertilizer water. At the same time, the fertilizer water also contains more harmful salts, and corresponding liquid medicine needs to be added to reduce the impact of harmful salts on crops. At present, during irrigation operations, the fertilizer water, liquid medicine and diluent are directly poured into the water tank and then mixed. At the same time, the water outlet pipe of the water tank is opened for irrigation. The overall operation is simple. However, in the actual working process, especially when the fertilizer water, the medicine liquid and the diluent are directly poured into the water tank, the water outlet pipe is always in an open state, that is, the mixed liquid just poured into the water tank will be discharged from the water outlet pipe outside the water tank, and the mixing effect of the fertilizer water, the medicine liquid and the diluent cannot be guaranteed, which leads to that the fertilizer water irrigation cannot play its due effect during irrigation. Moreover, since the fertilizer water still contains a certain amount of undissolved substances, the mixed liquid needs to be filtered during mixing. During the long irrigation process, the substances on the upper side of the filter net gradually increase, which will greatly affect the filtering effect of the filter net and the normal circulation effect of the mixed liquid, and seriously affect the overall irrigation efficiency. Moreover, during the irrigation process, the diameter of the water outlet pipe connected to the water tank is small, and even if the mixed liquid is filtered, it may still be blocked.

Compared with the traditional irrigation method, the method of adding fertilizer and liquid medicine in batches is used for irrigation. The mixing effect of fertilizer and liquid medicine is better, so it is better to maintain the desired effect of fertilizer irrigation; 2. Secondly, during the process of adding fertilizer water and liquid medicine, the moving frame and storage box will be driven to move. The storage box and the materials accumulated on the filter will offset each other, and the materials accumulated on the filter will move with the storage box.

Secondly, before starting the irrigation operation, first add an appropriate amount of liquid for adjusting the quality of fertilizer water into the liquid tank 9, then select a suitable number of outlet pipes 6 according to actual work needs, and then install a hose 8 on the outside of the outlet pipe 6, and move the hose 8 and the irrigation head 7 to the position where irrigation is required, start the first electromagnetic control valve 4 and the second electromagnetic control valve 10, add an appropriate amount of fertilizer water and liquid for adjusting the quality of fertilizer water into the water tank 2. , dilute the liquid medicine of the substance inside the fertilizer water. In this process, start the motor 11, and the motor 11 drives the stirring rod 13 to rotate through the rotating shaft 12 to stir the mixed water inside the water tank 2 to accelerate the mixing efficiency. Then close the first electromagnetic control valve 4, the second electromagnetic control valve 10 and the motor 11, and start the booster pump 5 on the outside of the water outlet pipe 6 connected to the hose 8, so that the mixed liquid inside the water tank 2 circulates through the water outlet pipe 6, the hose 8 and the irrigation head 7, and start the irrigation operation. Then, the electronic water gauge 15 is an instrument for monitoring the water level, which obtains data by measuring the water level of the electrode. Specifically in this solution, the electronic water gauge 15 can measure the water content in the water tank 2. When the water content inside the water tank 2 is When the water level is low, the electronic water gauge 15 can send out an electrical signal, and then automatically start the first electromagnetic control valve 4, the second electromagnetic control valve 10, the hydraulic rod 17 and the motor 11 through the controller. At this time, the fertilizer water enters the water tank 2 through the water inlet pipe 3. At the same time, the liquid medicine in the liquid medicine tank 9 flows into the water tank 2 through the second electromagnetic control valve 10, and the motor 11 is started again. The motor 11 drives the stirring rod 13 to rotate through the rotating shaft 12 to stir the mixed water inside the water tank 2 to accelerate the mixing efficiency. At the same time, the hydraulic rod 17 will drive the baffle 19 to move downward until the baffle 19 and the fixed ring 14 are against each other, causing the fixed ring 14 to be closed, and the mixed liquid inside the water tank 2 will not pass through the fixed ring 14. At this time, the fixed ring 14 is located in the fixed ring 14. The mixed liquid on the lower side of the fixed ring 14 will continue to be irrigated along the outlet pipe 6, the hose 8 and the irrigation head 7, and will not affect the normal irrigation effect. At the same time, when the mixed liquid on the upper side of the fixed ring 14 is more, the electronic water gauge 15 will send an electrical signal again, and then automatically close the first electromagnetic control valve 4, the second electromagnetic control valve 10, the hydraulic rod 17 and the motor 11. Under the action of the hydraulic rod 17, the baffle 19 will return to its original position relative to the shell 16, and the fixed ring 14 will be opened again to start normal circulation. Compared with the traditional irrigation method, the method of adding fertilizer water and liquid medicine in batches for irrigation has a better mixing effect of fertilizer water and liquid medicine, so it is better to maintain the desired effect of fertilizer water irrigation; A filter screen 20 is fixedly installed in the fixed ring 14, and a cleaning assembly is installed in the water tank 2. The cleaning assembly includes a first connecting rod 21 that rotates and penetrates the shell 16 and the fixed ring 14. The first connecting rod 21 is connected to the rotating shaft 12 through a first pulley assembly 22. Deep grooves 24 are opened on the inner walls on both sides of the fixed ring 14. The first connecting rod 21 rotates and penetrates one of the deep grooves 24. A first slide plate 25 is slidably connected in one of the deep grooves 24, and a second slide plate 27 is slidably connected in the other deep groove 24. A connecting rod is fixedly connected between the first slide plate 25 and the second slide plate 27. The first slide plate 25, the second slide plate 27 and the inner wall of the deep groove 24 are connected. A second spring 26 is fixedly connected between the first slide plate 25, a first rack 31 is fixedly connected to the side wall of the first slide plate 25, a first gear 32 is fixedly connected to the outer side of the first connecting rod 21, the first gear 32 and the first rack 31 are meshed, a first connecting plate 28 is slidably connected to the side walls of the first slide plate 25 and the second slide plate 27, and a third spring 29 is fixedly connected between the two first connecting plates 28 and the first slide plate 25 and the second slide plate 27, a second connecting rod 35 is fixedly connected to the side wall of the first connecting plate 28, and the two second connecting rods 35 are jointly fixedly connected to a moving frame 30, and storage boxes 34 are fixedly connected to the left and right sides of the moving frame 30; First, Figure 7 Based on the direction, when the first connecting rod 21 rotates counterclockwise, the first connecting rod 21 drives the first gear 32 to rotate counterclockwise, and the first gear 32 drives the meshing first rack 31 to move rightward. Under the action of the connecting rod, the first rack 31 drives the first slide plate 25 and the second slide plate 27 to move rightward. The first slide plate 25 and the second slide plate 27 both compress the second spring 26 on the right side and stretch the second spring 26 on the left side. At the same time, the first slide plate 25 and the second slide plate 27 both drive the first connecting plate 28 to move rightward through the third spring 29. The first connecting plate 28 drives the moving frame 30 to move rightward through the second connecting rod 35, and the moving frame 30 drives the storage box 34 to move rightward. In this process, the storage box 34 and the materials accumulated on the upper side of the filter screen 20 offset each other, so that the materials accumulated on the upper side of the filter screen 20 will move with the storage box 34. When there are more materials on the upper side of the filter screen 20, the materials at a high place will automatically enter the storage box 34, thereby reducing the materials accumulated on the upper side of the filter screen 20, thereby maintaining the normal filtering effect of the filter screen 20.

[0015] A first dredging assembly is installed in the water tank 2, and the first dredging assembly includes a third connecting rod 36 fixedly installed on the side wall of one of the first connecting plates 28, the side wall of the third connecting rod 36 is slidably connected to the second connecting plate 37, the upper side of the second connecting plate 37 is fixedly connected to the third connecting plate 38, the upper side of the third connecting plate 38 is fixedly connected to a plurality of cleaning rods 41, the lower side of the first slide plate 25 is fixedly connected to the ninth connecting plate 53, the side wall of the ninth connecting plate 53 is provided with an inclined groove 23, the inclined groove 23 is slidably connected to the inclined plate 52, the outer side of the inclined plate 52 is fixedly connected to the fourth connecting plate 43, and the side wall of the fourth connecting plate 43 is fixedly connected to the first connecting plate 53. Five connecting plates 44, two eighth connecting plates 49 are fixedly connected to the side wall of the first slide plate 25, a seventh connecting plate 48 is also slidably connected to the side wall of the first slide plate 25, a fourth spring 50 is fixedly connected between the seventh connecting plate 48 and the eighth connecting plate 49, a plurality of second racks 18 are evenly fixedly connected to the side wall of the seventh connecting plate 48, a sixth connecting rod 51 is fixedly connected to the lower side of the seventh connecting plate 48, the sixth connecting rod 51 slides through the fourth connecting plate 43, a second gear 33 is also fixedly connected to the outer side of the first connecting rod 21, the second gear 33 is meshed with one of the second racks 18, and the heights of the plurality of cleaning rods 41 are different; First, the third connecting plate 38 is located on the upper side of the fifth connecting plate 44 and abuts against the fifth connecting plate 44. Then, the diameter of the second gear 33 is larger than the diameter of the first gear 32. Secondly, during the rotation of the first connecting rod 21, when the second gear 33 is meshed with the second rack 18, since the angular velocities of the first gear 32 and the second gear 33 are the same, and the linear velocity of the second gear 33 is greater than the linear velocity of the first gear 32, the moving speed of the second rack 18 is greater than the moving speed of the first rack 31. When the second gear 33 and the second rack 18 are meshed and connected, since the moving speed of the second rack 18 is faster, the second rack 18 moves relative to the first rack 31 along the first slide plate 25, and the second rack 18 drives the seventh connecting plate 48 to move, so as to achieve the desired effect. Fig.11, at this time, the rotation direction of the first connecting rod 21 is still counterclockwise, the seventh connecting plate 48 compresses the fourth spring 50 on the left and stretches the fourth spring 50 on the right, and the seventh connecting plate 48 drives the sixth connecting rod 51 to move along the first slide plate 25. Under the restriction of the inclined groove 23 and the inclined plate 52, the fourth connecting plate 43 will be driven to move upward relative to the sixth connecting rod 51, the fourth connecting plate 43 drives the fifth connecting plate 44 to move upward, the fifth connecting plate 44 drives the third connecting plate 38 to move upward, and the third connecting plate 38 drives the cleaning rod 41 to move upward, and the cleaning rod 41 is inserted into the mesh of the filter screen 20 to dredge the mesh of the filter screen 20 to reduce the possibility of clogging of the mesh of the filter screen 20. Secondly, when the cleaning rod 41 enters the mesh of the filter screen 20, at this time, under the obstruction of the filter screen 20, the cleaning rod 41, the third connecting plate 38, and the moving frame 30 will stop following the movement of the first slide plate 25 and the second slide plate 27 as a whole, so as to prevent the cleaning rod 41 from entering the mesh of the filter screen 20. Fig. 9 The first connecting plate 28 compresses the third spring 29 on the rear side and stretches the third spring 29 on the front side. During this process, the cleaning rod 41 moves upward until the second gear 33 and the second rack 18 are disconnected. Then, under the action of the fourth spring 50, the fourth connecting plate 43 moves along the inclined groove 23 and the inclined plate 52, causing the fourth connecting plate 43 to move downward. The fourth connecting plate 43 drives the fifth connecting plate 44 to move downward, and the third connecting plate 38 follows the fifth connecting plate 44 to move downward. The cleaning rod 41 is driven by the third spring 29 to move downward until the cleaning rod 41 is removed from the mesh of the filter screen 20. At this time, under the action of the third spring 29, the cleaning rod 41, the third connecting plate 38, and the moving frame 30 move quickly as a whole until the cleaning rod 41, the third connecting plate 38, and the moving frame 30 return to the initial position relative to the first slide plate 25 and the second slide plate 27 as a whole. As a result, during the movement of the first slide plate 25 and the second slide plate 27, the cleaning rod 41 moves up and down all the time, which can form a dredging and cleaning effect on the mesh of the filter screen 20. Then, Fig.10 The direction is based, wherein in the front-to-back direction, the middle cleaning rod 41 is the highest, and then extends from the middle to both sides, and the height of the cleaning rod 41 gradually decreases. Therefore, when the cleaning rod 41 passes through the mesh of the filter 20, the material on the upper side of the cleaning rod 41 will move to both sides along the cleaning rod 41, and then fall into the storage box 34, which can not only complete the dredging effect of the mesh of the filter 20, but also allow the material blocking the mesh of the filter 20 to enter the storage box 34 along the cleaning rod 41, forming a collection effect on the material.

[0016] A second dredging assembly is also installed in the water tank 2, and the second dredging assembly includes a mounting rod 42 fixedly installed on the lower side of the third connecting rod 36, the outer side of the mounting rod 42 is threadedly connected with a mounting ring 47, the outer side of the mounting ring 47 is rotatably connected with a sixth connecting plate 46, a fifth connecting rod 45 is fixedly connected between the sixth connecting plate 46 and the second connecting plate 37, a fourth connecting rod 39 is rotatably connected to the lower side of the third connecting plate 38, a second pulley assembly is transmission-connected between the fourth connecting rod 39 and the mounting ring 47, a round table 40 is slidably installed on the lower side of the fourth connecting rod 39, the outer surface of the round table 40 is smoothly set, when the round table 40 and the water outlet pipe 6 are against each other, the water outlet pipe 6 will not prevent the round table 40 from moving with the third connecting plate 38; First, the fourth connecting rod 39 and the round table 40 are connected by sliding up and down. Secondly, in the process of the third connecting plate 38 moving up and down, the third connecting plate 38 drives the second connecting plate 37 to move up and down. The second connecting plate 37 drives the sixth connecting plate 46 to move up and down through the fifth connecting rod 45. The sixth connecting plate 46 drives the mounting ring 47 to move up and down. Since the mounting ring 47 and the mounting rod 42 are threadedly connected, the mounting ring 47 that moves up and down with the sixth connecting plate 46 will rotate relative to the sixth connecting plate 46. The mounting ring 47 drives the fourth connecting rod 39 to rotate through the second pulley assembly. The table 40 is driven to rotate, so that during the process of cleaning the filter screen 20, the table 40 not only moves but also rotates. Since the movement trajectory of the table 40 is relative to the water outlet pipe 6 in the water tank 2, the table 40 will enter the water outlet pipe 6 during its movement. Since the table 40 rotates, the rotating table 40 and the inner wall of the water outlet pipe 6 abut against each other, which can form a clearing effect on the water outlet pipe 6 and reduce the possibility of blockage of the water outlet pipe 6. In addition, during the above working process, there is no self-locking phenomenon between the mounting rod 42 and the mounting ring 47, that is, the thread lead angle is greater than the friction angle.

[0017] In the present invention, before the irrigation operation is started, a proper amount of liquid medicine for adjusting the quality of fertilizer water is first added to the liquid medicine tank 9, and then, according to the actual work needs, a proper number of outlet pipes 6 are selected, and then a hose 8 is installed on the outside of the outlet pipe 6, and the hose 8 and the irrigation head 7 are moved to the position where irrigation is required, and the first electromagnetic control valve 4 and the second electromagnetic control valve 10 are started, and a proper amount of fertilizer water and liquid medicine for adjusting and diluting the internal substances of the fertilizer water are added to the water tank 2. In this process, the motor 11 is started, and the motor 11 drives the stirring rod 13 to rotate through the rotating shaft 12 to stir the mixed water inside the water tank 2 to accelerate the mixing efficiency, and then the first electromagnetic control valve 4, the second electromagnetic control valve 10 and the motor 11 are closed, and the booster pump 5 on the outside of the outlet pipe 6 connected to the hose 8 is started, so that the mixed liquid inside the water tank 2 is circulated through the outlet pipe 6, the hose 8 and the irrigation head 7, and the irrigation operation is started; Then, the electronic water gauge 15 is an instrument for monitoring the water level, and data is obtained by measuring the water level of the electrode. Specifically in this solution, the electronic water gauge 15 can measure the amount of water in the water tank 2. When the water content inside the water tank 2 is low, the electronic water gauge 15 can send an electrical signal, and then automatically start the first electromagnetic control valve 4, the second electromagnetic control valve 10, the hydraulic rod 17 and the motor 11 through the controller. At this time, the fertilizer water enters the water tank 2 through the water inlet pipe 3. At the same time, the liquid medicine in the liquid medicine tank 9 flows into the water tank 2 through the second electromagnetic control valve 10, and the motor 11 is started again. The motor 11 drives the stirring rod 13 to rotate through the rotating shaft 12 to stir the mixed water inside the water tank 2 to accelerate the mixing efficiency. At the same time, the hydraulic rod 17 will drive the baffle 19 to move downward until the baffle 19 and the fixed ring 14 are against each other. As a result, the fixing ring 14 is closed, and the mixed liquid inside the water tank 2 will not pass through the fixing ring 14. At this time, the mixed liquid located on the lower side of the fixing ring 14 will continue to be irrigated along the outlet pipe 6, the hose 8 and the irrigation head 7, and will not affect the normal irrigation effect. At the same time, when the mixed liquid on the upper side of the fixing ring 14 is more, the electronic water gauge 15 will send an electrical signal again, and then automatically close the first electromagnetic control valve 4, the second electromagnetic control valve 10, the hydraulic rod 17 and the motor 11. Under the action of the hydraulic rod 17, the baffle 19 will return to its original position relative to the shell 16, and the fixing ring 14 will be opened again to start normal circulation. Compared with the traditional irrigation method, the method of adding fertilizer water and liquid medicine in batches for irrigation has a better mixing effect of fertilizer water and liquid medicine, so it is better to maintain the desired effect of fertilizer water irrigation; When the first connecting rod 21 rotates, the first connecting rod 21 drives the first gear 32 to rotate, and the first gear 32 drives the meshing first rack 31 to move. Under the action of the connecting rod, the first rack 31 drives the first slide plate 25 and the second slide plate 27 to move, and the first slide plate 25 and the second slide plate 27 generate a force on the second spring 26. At the same time, the first slide plate 25 and the second slide plate 27 both drive the first connecting plate 28 to move through the third spring 29, and the first connecting plate 28 drives the moving frame 30 to move through the second connecting rod 35, and the moving frame 30 drives the storage box 34 to move. In this process, the storage box 34 and the materials accumulated on the upper side of the filter screen 20 are offset, so that the materials accumulated on the upper side of the filter screen 20 will move with the storage box 34. When there are more materials on the upper side of the filter screen 20, the materials at the high place will automatically enter the storage box 34, thereby reducing the materials accumulated on the upper side of the filter screen 20, thereby maintaining the normal filtering effect of the filter screen 20. During the rotation of the first connecting rod 21, when the second gear 33 and the second rack 18 are meshed, since the angular velocities of the first gear 32 and the second gear 33 are the same, and the linear velocity of the second gear 33 is greater than the linear velocity of the first gear 32, the second rack 18 moves at a speed greater than the first rack 31. When the second gear 33 and the second rack 18 are meshed and connected, since the moving speed of the second rack 18 is faster, the second rack 18 moves relative to the first rack 31 along the first slide plate 25, and the second rack 18 drives the seventh connecting plate 48 to move, so as to achieve the desired effect. Fig.11 , at this time, the rotation direction of the first connecting rod 21 is still counterclockwise, the seventh connecting plate 48 compresses the fourth spring 50 on the left and stretches the fourth spring 50 on the right, and the seventh connecting plate 48 drives the sixth connecting rod 51 to move along the first slide plate 25. Under the restriction of the inclined groove 23 and the inclined plate 52, the fourth connecting plate 43 will be driven to move upward relative to the sixth connecting rod 51, the fourth connecting plate 43 drives the fifth connecting plate 44 to move upward, the fifth connecting plate 44 drives the third connecting plate 38 to move upward, and the third connecting plate 38 drives the cleaning rod 41 to move upward, and the cleaning rod 41 is inserted into the mesh of the filter screen 20 to dredge the mesh of the filter screen 20 to reduce the possibility of clogging of the mesh of the filter screen 20. Secondly, when the cleaning rod 41 enters the mesh of the filter screen 20, at this time, under the obstruction of the filter screen 20, the cleaning rod 41, the third connecting plate 38, and the moving frame 30 will stop following the movement of the first slide plate 25 and the second slide plate 27 as a whole, so as to prevent the cleaning rod 41 from entering the mesh of the filter screen 20. Fig. 9 The first connecting plate 28 compresses the third spring 29 on the rear side and stretches the third spring 29 on the front side. During this process, the cleaning rod 41 moves upward until the second gear 33 and the second rack 18 are disconnected. Then, under the action of the fourth spring 50, the fourth connecting plate 43 moves along the inclined groove 23 and the inclined plate 52, causing the fourth connecting plate 43 to move downward. The fourth connecting plate 43 drives the fifth connecting plate 44 to move downward, and the third connecting plate 38 follows the fifth connecting plate 44 to move downward. The connecting plate 38 drives the cleaning rod 41 to move downward until the cleaning rod 41 moves out of the mesh of the filter screen 20. At this time, under the action of the third spring 29, the cleaning rod 41, the third connecting plate 38, and the moving frame 30 move quickly as a whole until the cleaning rod 41, the third connecting plate 38, and the moving frame 30 return to the initial position relative to the first slide plate 25 and the second slide plate 27. As a result, during the movement of the first slide plate 25 and the second slide plate 27, the cleaning rod 41 keeps moving up and down, which can form a clearing and cleaning effect on the mesh of the filter screen 20. Then, Fig.10The cleaning rod 41 is the highest in the front-to-back direction, and then extends from the middle to both sides, and the height of the cleaning rod 41 gradually decreases. Therefore, when the cleaning rod 41 passes through the mesh of the filter 20, the material on the upper side of the cleaning rod 41 will move to both sides along the cleaning rod 41, and then fall into the storage box 34, which can not only dredge the mesh of the filter 20, but also allow the material that blocks the mesh of the filter 20 to enter the storage box 34 along the cleaning rod 41, thereby forming a collection effect on the material; During the up and down movement of the third connecting plate 38, the third connecting plate 38 drives the second connecting plate 37 to move up and down, the second connecting plate 37 drives the sixth connecting plate 46 to move up and down through the fifth connecting rod 45, and the sixth connecting plate 46 drives the mounting ring 47 to move up and down. Since the mounting ring 47 and the mounting rod 42 are threadedly connected, the mounting ring 47 that follows the up and down movement of the sixth connecting plate 46 will rotate relative to the sixth connecting plate 46, and the mounting ring 47 drives the fourth connecting rod 39 to rotate through the second pulley assembly, and the fourth connecting rod 39 drives the round table 40 to rotate, which results in that during the cleaning process of the filter screen 20, the round table 40 will not only move, but also rotate. Since the movement trajectory of the round table 40 is relative to the position of the water outlet pipe 6 in the water tank 2, the round table 40 will enter the water outlet pipe 6 during the movement of the round table 40. Since the round table 40 will rotate, the rotating round table 40 and the inner wall of the water outlet pipe 6 will abut against each other, which can form a dredging effect on the water outlet pipe 6 and reduce the possibility of blockage of the water outlet pipe 6.
