Description

Technical Field

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

[0002] Integrated water and fertilizer refers to a new technology that integrates irrigation and fertilization in agricultural production. By mixing the irrigation water with solid or liquid fertilizers and then transmitting them through pipes for drip irrigation, integrated water and fertilizer management can greatly reduce the time consumed by irrigation and fertilization respectively, and can allow solid fertilizers to penetrate into the ground more quickly to provide nutrition to crops, while meeting the different growth needs of crops. In this process, integrated water and fertilizer irrigation devices are needed.

[0003] However, in practical applications, there are still some unresolved problems. The following are some common problems of the integrated water-fertilizer irrigation device: In the prior art, the integrated water-fertilizer irrigation device cannot accurately add fertilizer for dissolution according to the amount of water, but most of them manually judge the amount of water, and add the roughly required amount of fertilizer to the device for dissolution, resulting in too low or too high water-fertilizer concentration after formation. If the water-fertilizer concentration is too low, it will lead to plant nutrient deficiency and affect the plant's stress resistance after irrigation. If the water-fertilizer concentration is too high, it will lead to a high fertilizer concentration in the soil after irrigation, which will cause reverse osmosis of water in crop cells, causing crop dehydration, and often causing crops to wilt. In mild cases, it affects the normal growth and development of crops, and in severe cases, it causes death. At the same time, it leads to increased soil salt concentration, destroys soil structure, and affects the balance of soil microorganisms. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1 Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and provides an integrated water and fertilizer irrigation device for crops. The integrated water and fertilizer irrigation device for crops includes an irrigation mechanism 100, a feeding mechanism 200 and a stirring and grinding mechanism 300. The irrigation operation of water and fertilizer can be realized through the irrigation mechanism 100, the fertilizer can be automatically added according to the amount of water through the feeding mechanism 200, and the solid fertilizer can be ground through the stirring and grinding mechanism 300, and the water and fertilizer can be quickly stirred, dissolved and mixed.

[0035] Specifically, the irrigation mechanism 100 includes a cart 101, a water tank 102, a water pump 103, a curved pipe 104, a transverse pipe 105 and a nozzle 106. The water tank 102 is fixedly connected to the top of the cart 101, the water pump 103 is fixedly connected to the top of the cart 101 and is connected to the water tank 102 and the curved pipe 104, the transverse pipe 105 is connected to the upper end of the curved pipe 104, and the nozzle 106 is connected to the surface of the transverse pipe 105.

[0036] The surface of the transverse pipe 105 and the curved pipe 104 are fixedly connected with a reinforcing rod, one end of which is fixedly connected to the surface of the water tank 102. The transverse pipe 105, the curved pipe 104 and the water tank 102 are reinforced by the reinforcing rod to improve stability. There are several nozzles 106, which are evenly distributed on the surface of the transverse pipe 105, thereby increasing the spraying area.

[0037] Specifically, the feeding mechanism 200 is installed on the surface of the water tank 102, and includes a fertilizer box 201, a cover plate 202, a feeding piece 203, a buoyancy piece 204, a limiting piece 205, a fixing piece 206, a positioning piece 207 and a cover body 208. The fertilizer box 201 is fixedly connected to the top of the water tank 102, the cover plate 202 is movably connected to the top of the fertilizer box 201, the feeding piece 203 is arranged on the surfaces of the fertilizer box 201 and the water tank 102, the buoyancy piece 204 is arranged on the surfaces of the water tank 102 and the feeding piece 203, the limiting piece 205 is arranged on the surface of the water tank 102, the fixing piece 206 is arranged on the surfaces of the water tank 102 and the cover body 208, the positioning piece 207 is arranged on the surface of the water tank 102, and the cover body 208 is fixedly connected to the surface of the water tank 102.

[0038] Adding water into the water tank 102 can drive the discharge part 203 to operate through the buoyancy part 204, and the corresponding fertilizer is added according to the amount of water added into the water tank 102 to avoid the concentration after mixing being too high or too low due to manual addition, so as to meet the irrigation needs. When the added fertilizer is stirred through the limit part 205, part of the structure on the buoyancy part 204 is unlocked to avoid large water fluctuations during the stirring and walking process and the gradual decrease of water volume during the fertilization process, which leads to the driving of the discharge part 203 to operate. The fertilizer is added into the water tank 102, causing the water-fertilizer concentration to exceed the demand, which not only leads to the waste of fertilizer, but also causes the sintering of crops due to the excessive fertilizer concentration.

[0039] The limiting member 205 driving the buoyancy member 204 is fixed by the fixing member 206, and the limiting member 205 can only be released manually. The vertical pipe 204c is positioned by the positioning member 207 under the drive of the limiting member 205, and then the second bevel gear 204d is positioned, so that the material discharge member 203 is positioned. The large water fluctuation during the stirring and walking process and the gradual decrease and bumping of the water volume during the fertilization process will not cause the material discharge member 203 to operate, thereby ensuring that the concentration of the water and fertilizer in the water tank 102 is consistent after mixing.

[0040] Specifically, the stirring and grinding mechanism 300 is installed on the surface of the water tank 102 and the fertilizer box 201, and includes a shell 301, a motor 302, a first ratchet member 303, a grinding member 304, a stirring member 305 and a cam 306. The shell 301 is fixedly connected to the surface of the water tank 102, the motor 302 is fixedly connected to the surface of the shell 301, the first ratchet member 303 is fixedly connected to the rotating shaft of the motor 302, the grinding member 304 is arranged on the surface of the fertilizer box 201 and the first ratchet member 303, the stirring member 305 is arranged on the surface of the water tank 102 and the first ratchet member 303, and the first ratchet member 303 and the cam 306 are arranged on the surface of the stirring member 305.

[0041] The first ratchet member 303 will not drive the stirring member 305 to rotate when the shaft of the motor 302 rotates forward, so that the water surface will not be stirred and float after water is added to the water tank 102, thereby ensuring the stability of fertilizer addition and reducing the impact. At the same time, the grinding member 304 can operate to grind the fertilizer in the fertilizer box 201 that enters the discharge member 203 to ensure better dissolution when entering the water in the water tank 102.

[0042] When the motor 302 is controlled to rotate in the opposite direction, the stirring member 305 and the cam 306 can be driven to operate. When the cam 306 rotates one circle, it can act on the limit member 205, thereby causing the convex frame 204f to move upward, so that the movable member 204e loses the effect between the vertical tube 204c and the vertical rod 204b. At this time, the stirring member 305 only runs one circle and does not cause a large fluctuation in the water surface. Thereafter, even if the vertical rod 204b rises or falls, the vertical tube 204c will not rotate, and the unloading member 203 will not unload the material. The fertilizer and water added to the water tank 102 are stirred by the stirring member 305 to increase the dissolution rate.

[0043] Example 2 Reference Figure 3 to Figure 12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0044] Specifically, the unloading member 203 includes a cylinder 203a, which is connected between the top of the water tank 102 and the bottom of the fertilizer box 201. A rotating rod 203b is rotatably connected to the surface of the cylinder 203a, and one end of the rotating rod 203b is fixedly connected to the first bevel gear 203c. A cylinder 203d is sleeved on the surface of the rotating rod 203b, and a baffle 203e is slidably connected to the surface of the cylinder 203d. A first spring 203f is fixedly connected inside the cylinder 203d, and one end of the first spring 203f is fixedly connected to the baffle 203e. A limiting block 203g is fixedly connected to the surface of the baffle 203e, and the limiting block 203g is slidably connected to the inner wall of the cylinder 203d, and the baffle 203e is slidably connected to the inner wall of the cylinder 203a.

[0045] The rotating rod 203b is rotatably connected to the surface of the cylinder 203a through a bearing. There are several baffles 203e and the first spring 203f, and the number is the same. The fertilizer entering the cylinder 203a can be evenly discharged through the rotation of the baffle 203e, and it plays a closing role when the rotation stops. The first spring 203f allows the baffle 203e to better contact with the inner wall of the cylinder 203a, and even if it is worn out after long-term use, it can maintain good contact. The baffle 203e is limited and guided by the limit block 203g to prevent the baffle 203e from separating from the cylinder 203d.

[0046] The buoyancy member 204 includes a square rod 204a, which is fixedly connected to the bottom of the water tank 102. A vertical rod 204b is sleeved on the surface of the square rod 204a. A vertical pipe 204c is sleeved on the surface of the vertical rod 204b. The lower end of the vertical pipe 204c is rotatably connected to the top of the water tank 102. A second bevel gear 204d is sleeved on the surface of the vertical pipe 204c. A movable member 204e is installed on the surface of the vertical pipe 204c. A convex frame 204f is installed on the surface of the limiting member 205. The convex frame 204f is arranged on the surface of the movable member 204e. A floating body 204g is fixedly connected to the surface of the vertical rod 204b. A guide groove 204h is opened on the surface of the vertical rod 204b. A positioning hole 204i is opened on the surface of the vertical pipe 204c. The first bevel gear 203c is meshed with the second bevel gear 204d.

[0047] The vertical rod 204b is slidably sleeved on the surface of the square rod 204a, and the vertical rod 204b is guided and limited by the square rod 204a, so that the float 204g will not rotate when the vertical rod 204b is driven upward by the buoyancy of the water. Similarly, during the descent process, the different effects of the convex frame 204f on the movable part 204e can be used to determine whether there is a connection between the vertical rod 204b and the vertical tube 204c. When the movable part 204e is located in the upper half of the convex frame 204f, the vertical tube 204c can be rotated during the upward movement of the vertical rod 204b, thereby driving the rotation of the second bevel gear 204d, thereby driving the operation of the unloading part 203. According to the water volume in the water tank 102, the rising positions of the float 204g and the vertical rod 204b are used for corresponding unloading, so as to ensure that the obtained water and fertilizer concentration is the concentration required for irrigation.

[0048] The vertical tube 204c and the vertical rod 204b are connected or unlocked by inserting the guide column 204e-2 on the movable part 204e into the guide groove 204h on the vertical rod 204b. There are several positioning holes 204i, which are distributed circumferentially on the surface of the vertical tube 204c. The positioning column 207d on the positioning part 207 is inserted therein, so that the vertical tube 204c and the second bevel gear 204d are positioned and will not rotate, thereby positioning the first bevel gear 203c, the rotating rod 203b, the cylinder 203d and the baffle 203e and will not rotate.

[0049] The limiting member 205 includes a short block 205a, which is fixedly connected to the surface of the water tank 102. A movable plate 205b is slidably connected to the surface of the short block 205a. A tooth 205c is fixedly connected to the surface of the movable plate 205b. A roller 205d is fixedly connected to the lower end of the movable plate 205b. A wedge block 205e is fixedly connected to the surface of the movable plate 205b. A handle 205f is fixedly connected to the upper end of the movable plate 205b. A second spring 205g is sleeved on the surface of the movable plate 205b. Two ends of the second spring 205g are respectively fixedly connected to the movable plate 205b and the surface of the short block 205a. The convex frame 204f is fixedly connected to the surface of the movable plate 205b. The roller 205d is movably connected to the cam 306.

[0050] There are two short blocks 205a, and the movable plate 205b passes through the short blocks 205a and is slidably connected thereto. When the cam 306 rotates to lift the roller 205d and the movable plate 205b, the teeth 205c move up with the movable plate 205b to drive the circular gear 206c and the outer ring of the second ratchet member 206b to rotate forwardly. Then, as the outer ring of the first ratchet member 303 cannot move down and reverse with the teeth 205c, the teeth 205c and the movable plate 205b are fixed, and then the convex frame 204f and the wedge block 205e that move up with the movable plate 205b are fixed, so that the movable member 204e is located in the lower half of the convex frame 204f, so that the vertical pipe 204c and the vertical rod 204b are unlocked.

[0051] The second spring 205g provides power for resetting the movable plate 205b, the wedge block 205e, the convex frame 204f and the teeth 205c. When the fixing member 206 releases the fixation of the movable plate 205b, the handle 205f can be held to manually provide power for resetting the movable plate 205b, the wedge block 205e, the convex frame 204f and the teeth 205c.

[0052] The fixing member 206 includes a short rod 206a, which is rotatably connected to the surface of the water tank 102. The surface of the short rod 206a is sleeved with a second ratchet member 206b, and the surface of the second ratchet member 206b is sleeved with a circular gear 206c. One end of the short rod 206a is fixedly connected to a short plate 206d, and the surface of the short plate 206d is slidably connected to a fixing rod 206e. The surface of the fixing rod 206e is sleeved with a round block 206f, a third spring 206g and a sleeve 206h, and the two ends of the third spring 206g are respectively movably connected to the round block 206f and the short plate 206d. A fixing hole that cooperates with the fixing rod 206e is opened on the surface of the cover body 208, and the fixing rod 206e is inserted into the fixing hole.

[0053] The short rod 206a is rotatably connected to the surface of the water tank 102 through a bearing. When the second ratchet member 206b moves up on the teeth 205c to drive the circular gear 206c to rotate, its outer ring rotates forward. However, when the cam 306 lifts the roller 205d and the movable plate 205b to the highest position, under the action of the elastic force of the second spring 205g and gravity, the outer ring of the second ratchet member 206b will not rotate in the opposite direction, and the movable plate 205b and the corresponding structure will not descend. The round block 206f is fixedly connected to the surface of the fixed rod 206e, and the third spring 206g and the sleeve 206h are movably connected to the surface of the fixed rod 206e.

[0054] The third spring 206g, under its elastic force, allows the fixing rod 206e to be stably inserted into the fixing hole to prevent the fixing rod 206e from being unintentionally separated from the fixing hole on the cover body 208. The sleeve 206h is held to pull the fixing rod 206e to move the round block 206f, and the third spring 206g is compressed. Then, the sleeve 206h is rotated to rotate the fixing rod 206e, the short plate 206d, the short rod 206a and the second ratchet wheel 206b. Under the action of the second spring 205g, the movable plate 205b, the wedge block 205e, the convex frame 204f, the roller 205d and the teeth 205c are reset.

[0055] The positioning member 207 includes a support rod 207a, the lower end of the support rod 207a is fixedly connected to the top of the water tank 102, the other end of the support rod 207a is fixedly connected to a block 207b, the surface of the block 207b is slidably connected to a square column 207c, one end of the square column 207c is fixedly connected to a positioning column 207d, the other end of the square column 207c is fixedly connected to an inclined block 207e, a fourth spring 207f is sleeved on the surface of the square column 207c, and the two ends of the fourth spring 207f are respectively fixedly connected to the surfaces of the block 207b and the inclined block 207e.

[0056] The square block 207b is supported and fixed by the support rod 207a, the square column 207c penetrates the square block 207b and is slidably connected thereto, and the wedge block 205e moves upward with the movable plate 205b to squeeze and move the inclined block 207e, thereby moving the square column 207c and the positioning column 207d, and the compression of the fourth spring 207f causes the positioning column 207d to be inserted into the positioning hole 204i, limiting the vertical pipe 204c, and thus positioning the baffle 203e in the discharge member 203 so that it will not rotate, so that it will not be affected by water fluctuations during stirring, water reduction and bumps during fertilization, and when the wedge block 205e is separated from the inclined block 207e, the positioning column 207d is separated from the positioning hole 204i, and the vertical pipe 204c is no longer restricted.

[0057] Example 3 Reference Figure 7 to Figure 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0058] Specifically, the grinding member 304 includes a belt pulley 304a, which is sleeved on the surface of the first ratchet member 303. A long rod 304b is rotatably connected to the surface of the fertilizer box 201. A belt pulley 304c is sleeved on one end of the long rod 304b, and a grinding roller 304d is fixedly connected to the other end of the long rod 304b. Belts 304e are sleeved on the surfaces of the belt pulleys 1 304a and 304c.

[0059] The long rod 304b is rotatably connected to the surface of the fertilizer box 201 through a bearing. The rotation of the outer ring of the second ratchet member 206b is driven by the belt pulley 1 304a, the belt 304e and the belt pulley 2 304c, so that the long rod 304b and the grinding roller 304d rotate, thereby grinding the fertilizer in the fertilizer box 201 so that it can be added to the water in the water tank 102 for better dissolution.

[0060] The stirring member 305 includes a cross bar 305a, which is rotatably connected to the surface of the water tank 102, and a fixed wheel 305b is fixedly connected to the inner wall of the water tank 102. A connecting plate 305c is sleeved on the surface of the cross bar 305a, and a round rod 305d is rotatably connected to the surface of the connecting plate 305c. A movable wheel 305e is fixedly connected to one end of the round rod 305d, and a stirring paddle 305f is sleeved on the surface of the round rod 305d. The first ratchet member 303 is sleeved on one end of the cross bar 305a, and the cam 306 is fixedly connected to the other end of the cross bar 305a. The fixed wheel 305b cooperates with the movable wheel 305e.

[0061] The cross bar 305a is rotatably connected to the surface of the water tank 102 through a sealed bearing. The rotation of the cross bar 305a drives the connecting plate 305c to rotate, and the round rod 305d, the movable wheel 305e and the stirring paddle 305f to revolve. Under the action of the fixed wheel 305b, the movable wheel 305e rotates, and then the revolving round rod 305d and the stirring paddle 305f rotate at the same time, so that the water and fertilizer are quickly stirred, dissolved and mixed, the time required for stirring and dissolving is reduced, and the efficiency is improved.

[0062] Example 4 Reference Figure 7 to Figure 9 , which is the fourth embodiment of the present invention, and this embodiment is based on the first three embodiments.

[0063] Specifically, the movable part 204e includes a movable column 204e-1, which is slidably connected to the surface of the vertical tube 204c, one end of the movable column 204e-1 is fixedly connected to the guide column 204e-2, the other end of the movable column 204e-1 is fixedly connected to the fixed block 204e-3, the guide column 204e-2 is slidably connected in the guide groove 204h, and the surface of the movable column 204e-1 is sleeved with a fifth spring 204e-4, and the two ends of the fifth spring 204e-4 are respectively fixedly connected to the surface of the vertical tube 204c and the fixed block 204e-3.

[0064] The movable column 204e-1 passes through the vertical tube 204c and is slidably connected thereto. It moves upward with the vertical rod 204b through the guide groove 204h to act on the guide column 204e-2, thereby rotating the vertical tube 204c and the movable part 204e, causing the second bevel gear 204d to rotate and drive the first bevel gear 203c and the rotating rod 203b to rotate.

[0065] The surface of the fixed block 204e-3 is slidably connected with a sliding column 204e-5, one end of the sliding column 204e-5 is fixedly connected with a movable block 204e-6, the surface of the movable block 204e-6 is rotatably connected with a ball 204e-7, the surface of the sliding column 204e-5 is sleeved with a sixth spring 204e-8, the two ends of the sixth spring 204e-8 are respectively fixedly connected to the fixed block 204e-3 and the movable block 204e-6, the surface of the vertical pipe 204c is fixedly connected with a limiting column 204e-9, the top of the movable column 204e-1 is provided with a limiting groove 204e-10 which cooperates with the limiting column 204e-9, and the limiting column 204e-9 is slidably connected in the limiting groove 204e-10.

[0066] The sliding column 204e-5 passes through the fixed block 204e-3 and is slidably connected thereto. The elastic force compressed by the sixth spring 204e-8 with the same deformation amount is greater than the elastic force compressed by the fifth spring 204e-4. When the guide column 204e-2 needs to be reinserted into the guide groove 204h, there are two situations. The first situation is that when the convex frame 204f moves downward, the movable part 204e moves from the lower half to the upper half in the convex frame 204f, and the guide column 204e-2 on the movable part 204e is directly inserted into the guide groove 204h.

[0067] The second type cannot be inserted directly, but under the action of the sixth spring 204e-8 and the fifth spring 204e-4, the guide column 204e-2 can contact the surface of the vertical rod 204b, and then as the vertical rod 204b moves slightly upward, the guide column 204e-2 can be inserted into the guide groove 204h under the action of elastic force, and the ball 204e-7 is used to reduce the resistance between the movable block 204e-6 and the convex frame 204f, so that the movable part 204e and the vertical tube 204c can rotate more smoothly.

[0068] When in use, the present invention has three working states. The first working state is to automatically add corresponding materials according to the amount of water, and at the same time, no stirring and dissolving is performed to avoid affecting the amount of fertilizer discharge, ensuring that the water-fertilizer concentration is within the required range, and controlling the motor 302 shaft to rotate in the opposite direction. Under the action of the first ratchet member 303, the stirring member 305 will not be driven to rotate, and the grinding member 304 can be operated. The grinding roller 304d on the grinding member 304 rotates to grind the fertilizer entering the discharge member 203 from the fertilizer box 201.

[0069] When water is added into the water tank 102, the float 204g causes the vertical rod 204b to move upward as the amount of water in the water tank 102 increases, and acts on the guide column 204e-2 as the vertical rod 204b moves upward through the guide groove 204h, thereby causing the vertical pipe 204c and the movable part 204e to rotate, and the second bevel gear 204d rotates to drive the first bevel gear 203c and the rotating rod 203b to rotate, thereby causing the cylinder 203d and the baffle 203e to rotate, and the fertilizer entering the cylinder 203a is evenly discharged, so that the corresponding material is automatically added according to the amount of water, and the discharge is stopped when the water injection stops.

[0070] The second working state is that when the water fertilizer preparation is stirred and dissolved, the feeding device is not affected by the water volume and the fluctuation of the water surface caused by stirring, and the walking bumps will not cause the feeding device to feed, and the positive rotation of the motor 302 shaft is controlled, so that the first ratchet wheel 303 is rotated as a whole, so that the cross bar 305a and the cam 306 rotate, and when the cam 306 rotates one circle, the roller 205d and the movable plate 205b are lifted, and the teeth 205c are moved along with the movable plate 205b. The circular gear 206c and the outer ring of the second ratchet member 206b are driven to rotate in the forward direction, and then the outer ring of the first ratchet member 303 cannot move downward and reverse with the teeth 205c, so the teeth 205c and the movable plate 205b are fixed, and then the convex frame 204f and the wedge block 205e that move upward with the movable plate 205b are fixed, so that the movable member 204e is located in the lower half of the convex frame 204f, so that the vertical tube 204c and the vertical rod 204b are unlocked.

[0071] The wedge block 205e moves upward with the movable plate 205b, squeezing and moving the inclined block 207e, thereby moving the square column 207c and the positioning column 207d, and compressing the fourth spring 207f, so that the positioning column 207d is inserted into the positioning hole 204i, limiting the vertical pipe 204c, and then positioning the baffle 203e in the discharge member 203 so that it will not rotate, so that it will not be affected by water fluctuations during stirring, water reduction and bumps during fertilization. During the fertilization process, the amount of remaining water in the water tank 102 can be judged by observing the length of the vertical rod 204b extending out of the cover body 208.

[0072] The rotation of the cross bar 305a drives the connection plate 305c to rotate, as well as the round rod 305d, the movable wheel 305e and the stirring paddle 305f to revolve. Under the action of the fixed wheel 305b, the movable wheel 305e rotates, and then the revolving round rod 305d and the stirring paddle 305f rotate at the same time, so that the water and fertilizer are quickly stirred, dissolved and mixed. The operation of the water pump 103 can be controlled to spray the water and fertilizer in the water tank 102 from the nozzle 106 through the curved pipe 104 and the cross pipe 105 to achieve irrigation.

[0073] After watering is completed, hold the sleeve 206h and pull the fixed rod 206e to move the round block 206f and compress the third spring 206g, then rotate the sleeve 206h to rotate the fixed rod 206e, the short plate 206d, the short rod 206a and the second ratchet member 206b, and reset the corresponding structure under the action of the second spring 205g. When the fixed member 206 releases the fixation of the movable plate 205b, the handle 205f can be held to manually provide power for the reset of the movable plate 205b, the wedge block 205e, the convex frame 204f, the teeth 205c and the movable member 204e, so as to prepare for the next water and fertilizer watering in advance.

[0074] The third working state is that water irrigation can be carried out directly by controlling the forward rotation of the motor 302 shaft, thereby making the first ratchet part 303 rotate as a whole, so that the cross bar 305a and the cam 306 rotate. When the cam 306 rotates one circle, the vertical pipe 204c and the vertical rod 204b are unlocked, and the unloading part 203 is restricted, and it is not affected by the upward movement of the float 204g and the vertical rod 204b. Then, the motor 302 is turned off, water is added to the water tank 102, and the operation of the water pump 103 is controlled to spray the water in the water tank 102 through the bend pipe 104 and the cross pipe 105 from the nozzle 106 to achieve irrigation.

[0075] In summary, the feeding mechanism 200 can automatically add fertilizer according to the amount of water. Compared with the prior art, it can avoid the situation where the concentration after mixing is inappropriate due to manual addition. The stirring and grinding mechanism 300 can grind the solid fertilizer. Compared with the prior art, the solid fertilizer added to the water can be better dissolved. At the same time, the water and fertilizer can be quickly stirred, dissolved and mixed, which reduces the time required for dissolution and improves efficiency.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
