Description

Technical Field

[0001] The present invention relates to the technical field of agriculture, and in particular to an intelligent nutrient solution supply device for plant cultivation. Background Art

[0002] The intelligent nutrient solution supply device is a device that can accurately allocate and automatically supply nutrient solution according to the growth needs of plants. It includes a water-fertilizer integrated machine. The water-fertilizer integrated machine can accurately mix fertilizer and water in a certain proportion according to preset parameters and deliver them to the roots of crops, ensuring that crops obtain the right amount of nutrients and water, avoiding waste and pollution to the environment caused by excessive fertilization and irrigation. The water-fertilizer integrated machine intercepts and filters suspended impurities in the irrigation water through a mesh filter to prevent these impurities from entering the pipe system and fertilization device of the water-fertilizer integrated machine, avoiding clogging of nozzles, drippers, and damage to components such as water pumps and valves. The mesh filter is long-lasting. During the use of time, it needs to be disassembled and cleaned regularly. Disassembling and cleaning the mesh filter usually requires manual operation. The staff needs to remove the filter from the water and fertilizer integrated machine, then carefully clean the filter, and then reinstall it. This process is relatively cumbersome, and in the process of disassembling and cleaning the filter, the entire system of the water and fertilizer integrated machine needs to stop running, which will affect the irrigation efficiency, and it is difficult for the staff to determine the cleaning cycle of the mesh filter. If the cleaning cycle is too long, a large amount of impurities will accumulate on the filter. As the impurities continue to increase, the pores of the filter are gradually blocked, the resistance to water flow increases, and the filtering effect decreases. Summary of the Invention

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. 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.

[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example

[0029] Reference Figure 1 、 Figure 2 and Figure 7 , which is the first embodiment of the present invention, provides an intelligent nutrient solution supply device for plant cultivation. The intelligent nutrient solution supply device for plant cultivation includes a main body component 100, including a stirring barrel 101. A stirrer is provided on the top of the stirring barrel 101 for stirring and mixing the fertilizer and water inside the stirring barrel 101. A pipe 102 is provided above the stirring barrel 101. A mounting sleeve 103 is fixed to one side of the pipe 102. One end of the pipe 102 located in the mounting sleeve 103 is L-shaped, and the end is rotatably connected to a rotating sleeve. A mesh filter 104 is provided in the mounting sleeve 103. The nutrient solution flowing out of the pipe 102 will enter the mesh filter 104, flow out from the outside of the mesh filter 104, and flow into the pipe 102 below, and small particles and floating objects in the water are filtered through the mesh filter 104.

[0030] When the mesh filter 104 is inserted into the installation sleeve 103 , it is clamped on the outside of the rotating sleeve and is tightly fixed to the rotating sleeve, so that the mesh filter 104 can rotate when receiving a thrust.

[0031] One side of the mounting sleeve 103 is connected to a sealing cover by bolts, and one side of the sealing cover is rotatably connected to a protrusion. When the sealing cover is fixed to the mounting sleeve 103, the protrusion will be stuck in the mesh filter 104, thereby blocking the outlet at the end of the mesh filter 104 and preventing water from flowing out through the end of the mesh filter 104.

[0032] The cleaning assembly 200 is arranged in the mounting sleeve 103 and includes a flushing part 201. The flushing part 201 includes a diverter pipe 201a fixed to one side of the pipe 102. The other end of the diverter pipe 201a passes through the mounting sleeve 103 and is fixed with a connecting pipe 201b. A nozzle 201c is provided on the connecting pipe 201b. There are multiple nozzles 201c, which are evenly distributed in a straight line on one side of the connecting pipe 201b. The nozzle 201c is inclined toward one side of the mesh filter 104. A force-bearing plate 201d is fixed to the outside of the mesh filter 104. There are multiple force-bearing plates 201d, which are evenly distributed in a ring shape on the outside of the mesh filter 104.

[0033] When the nutrient solution flows in the pipe 102 toward the inside of the mounting sleeve 103, it will first enter the diversion pipe 201a and the connecting pipe 201b, and then be sprayed toward the outside of the mesh filter 104 through the nozzle 201c, thereby backwashing the mesh filter 104 and separating the impurities attached to the inside of the mesh filter 104 from its inner wall. The liquid sprayed from the nozzle 201c will impact the force-bearing plate 201d and push the force-bearing plate 201d, thereby driving the mesh filter 104 to rotate through the force-bearing plate 201d, and then cleaning different positions of the mesh filter 104, thereby ensuring that the mesh filter 104 is thoroughly unblocked.

[0034] A sewage pipe 201e is fixed on one side of the pipe 102, and the other end of the sewage pipe 201e passes through the outside of the mounting sleeve 103. The sewage pipe 201e is connected to the pipe 102. After the mesh filter 104 is cleaned, the sewage flowing into the sewage pipe 201e will enter the sewage pipe 201e and flow outward through the sewage pipe 201e, so as to avoid the sewage remaining inside the pipe 102 and clogging the mesh filter 104 again.

[0035] The diameter of the sewage pipe 201e is smaller than that of the diversion pipe 201a (not shown in the figure). Therefore, the speed at which the liquid flows into the installation sleeve 103 through the diversion pipe 201a is greater than the speed at which the liquid is discharged outward from the sewage pipe 201e. Therefore, the liquid that cannot be discharged in time will accumulate inside the pipe 102, and the water level inside the pipe 102 will gradually rise. Example

[0036] Reference Figure 2-Figure 6 and Figure 8 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0037] Specifically, the cleaning component 200 also includes a first blocking member 202, which is located inside the pipe 102 above the installation sleeve 103. The first blocking member 202 includes a support ring 202a fixed to the inner wall of the pipe 102. A baffle 202b is provided at the bottom of the support ring 202a. The baffle 202b is fitted with the bottom of the support ring 202a, and a seal is performed between the two. The nutrient solution flowing inside the pipe 102 is intercepted by the baffle 202b, so that it cannot flow directly downward into the installation sleeve 103, but will enter the diversion pipe 201a.

[0038] A connecting block 202c is fixed to one side of the baffle 202b, a hinge seat 202d is fixed to the bottom of the support ring 202a, a rotating shaft is fixed inside the connecting block 202c, and the rotating shaft is movably connected to the hinge seat 202d. The baffle 202b is installed and positioned by the cooperation of the three. A torsion spring 202e is provided on one side of the hinge seat 202d, one end of the torsion spring 202e is fixed to the rotating shaft, and the other end is fixed to the hinge seat 202d. The torsion spring 202e applies an upward torsional force to the baffle 202b so that it can be reset after opening.

[0039] Specifically, the cleaning assembly 200 also includes a second sealing member 203, which is located inside the pipe 102 below the mounting sleeve 103. The second sealing member 203 includes a positioning ring 203a fixed to the inner wall of the pipe 102. An interception plate 203b is provided at the bottom of the positioning ring 203a. The interception plate 203b is hinged to the bottom of the positioning ring 203a. During the cleaning process of the mesh filter 104, the liquid is intercepted by the interception plate 203b to prevent the liquid from being discharged outward through the pipe 102.

[0040] A connecting column 203c is provided on the top of the intercepting plate 203b, and a pulley 203d is provided on the end of the connecting column 203c. The pulley 203d is rotatably connected to the connecting column 203c through a rotating shaft. Pulleys 203d are provided at both ends of the connecting column 203c, and a positioning sleeve 203e is provided on the outside of the pulley 203d. There are two positioning sleeves 203e, which are respectively located at the bottom of the baffle 202b and the top of the intercepting plate 203b and are connected by the connecting column 203c. The connecting column 203c is movably connected to the inside of the bend of the pipe 102, and the two fit tightly.

[0041] When the baffle 202b is in a horizontal state, a pulling force is applied to the intercepting plate 203b through the connecting column 203c, so that the intercepting plate 203b is also in a horizontal state and intercepts the liquid. When the baffle 202b rotates downward, the intercepting plate 203b can be pushed to rotate downward through the connecting column 203c, so that the intercepting plate 203b can be opened downward.

[0042] Specifically, the cleaning component 200 also includes a locking member 204, which includes a support frame 204a fixed to the inner wall of the pipe 102. A card block 204b is provided in the support frame 204a. The bottom side of the card block 204b is inclined, and the top is in contact with the baffle 202b. The baffle 202b is limited by the card block 204b so that it cannot rotate downward when it is subjected to the pressure of the liquid, thereby blocking and intercepting the liquid.

[0043] A first spring 204c is fixed to one side of the block 204b, and the other end of the first spring 204c is fixed to the inner wall of the support frame 204a. When the baffle 202b rotates upward, it will contact the inclined surface of the block 204b and push the block 204b to move, so that the baffle 202b can be upwardly fitted with the support ring 202a. At this time, the first spring 204c applies a thrust to the block 204b, so that the block 204b moves to the bottom of the baffle 202b and limits the baffle 202b. The elastic force of the torsion spring 202e is greater than the first spring 204c.

[0044] Specifically, the cleaning component 200 also includes a pushing member 205, which includes a floating block 205a located below the baffle 202b. The floating block 205a has buoyancy, and an extrusion rod 205b is fixed to the top of the floating block 205a. A force groove 204b-1 is opened on the clamping block 204b, and the inner wall of the force groove 204b-1 is inclined. The extrusion rod 205b corresponds to the force groove 204b-1.

[0045] During the cleaning process of the mesh filter 104, due to the small diameter of the sewage pipe 201e, the liquid is discharged slowly, and the water level inside the pipe 102 rises. When the water level contacts the floating block 205a, it will drive the floating block 205a and the squeezing rod 205b to move upward, so that the squeezing rod 205b approaches the force-bearing groove 204b-1 and squeezes the inner wall of the force-bearing groove 204b-1. Through the cooperation of the two, the card block 204b is driven to move, so that the card block 204b is separated from the bottom of the baffle 202b, thereby releasing the restriction on the baffle 202b. At this time, the baffle 202b can rotate downward under the pressure of the water flow, thereby stopping the cleaning work and allowing the mesh filter 104 to filter the liquid normally.

[0046] The buoyancy of the floating block 205a is relatively large, and can stably overcome the elastic force of the first spring 204c.

[0047] A guide rod 205c is fixed to the inner wall of the pipe 102. The guide rod 205c is rectangular. The floating block 205a is movably connected to the outer side of the guide rod 205c. The floating block 205a is positioned by the guide rod 205c.

[0048] Specifically, the cleaning component 200 also includes an intercepting member 206, which includes a fixed frame 206a fixed on the sewage pipe 201e, a plug plate 206b is inserted into the fixed frame 206a, and the plug plate 206b is movably connected to the fixed frame 206a. A guide wheel 206c is provided on one side of the fixed frame 206a, and a pull rope 206d is wrapped around the outside of the guide wheel 206c. The guide wheel 206c is used to guide and position the pull rope 206d, and the two ends of the pull rope 206d are respectively fixed to the plug plate 206b and the connecting column 203c.

[0049] When the baffle 202b opens downward and drives the connecting column 203c to move downward, the connecting column 203c will drive the pull rope 206d to move, and drive the plug plate 206b to move into the fixed frame 206a through the pull rope 206d. At this time, the drain pipe 201e is blocked by the plug plate 206b to prevent the liquid from flowing out through the drain pipe 201e when flowing into the mesh filter 104, thereby causing liquid waste. Example

[0050] Reference Figures 1-8 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0051] Specifically, a stabilizing block 206e is fixed to one side of the fixed frame 206a, a stabilizing column 206f is fixed to one side of the stabilizing block 206e, and a connecting plate 206g is fixed to one side of the plug plate 206b. The stabilizing column 206f is movably connected to the connecting plate 206g, and a second spring 206h is sleeved on the outside of the stabilizing column 206f. The two ends of the second spring 206h are respectively fixed to the connecting plate 206g and the stabilizing block 206e. When the connecting column 203c moves upward and does not pull the pull rope 206d, the second spring 206h applies a thrust to the connecting plate 206g, and the plug plate 206b is driven to move toward the outside of the fixed frame 206a through the connecting plate 206g, thereby releasing the blockage of the sewage pipe 201e.

[0052] Specifically, a sealing sleeve 207 is provided in the pipeline 102 and above the diversion pipe 201a. The sealing sleeve 207 is annular and fits tightly against the inner wall of the pipeline 102. The sealing sleeve 207 is located above the inlet of the diversion pipe 201a. A connecting rod 208 is rotatably connected inside the sealing sleeve 207. The bottom end of the connecting rod 208 is hinged to the baffle 202b. When the baffle 202b is rotated downward to open, the sealing sleeve 207 is driven downward by the connecting rod 208, and the inlet of the diversion pipe 201a is blocked by the sealing sleeve 207, so as to prevent the liquid from entering the inside of the diversion pipe 201a at this time.

[0053] Specifically, a centrifugal filter 105 is provided on the pipe 102, and the centrifugal filter 105 is used to filter large and small particles in the water. A water and fertilizer machine 106 is provided on one side of the mixing barrel 101. The water and fertilizer machine 106 can accurately mix fertilizer and water in a certain proportion according to preset parameters and transport them to the roots of crops, thereby ensuring that crops obtain an appropriate amount of nutrients and water, avoiding waste and pollution to the environment caused by excessive fertilization and irrigation. This is a prior art, and this solution will not be elaborated on, and those skilled in the art can clearly understand the working principle.

[0054] Specifically, a drain pipe 107 is provided on one side of the installation sleeve 103 , and a valve is provided on the drain pipe 107 . The drain pipe 107 can discharge the sewage remaining in the installation sleeve 103 to the outside.

[0055] During use, under the control of the water and fertilizer machine 106, the nutrient solution inside the mixing barrel 101 is temporarily prevented from entering the pipe 102. At this time, only filtered water in the pipe 102 flows to the inside of the installation sleeve 103. The water flow will first enter the diversion pipe 201a and the connecting pipe 201b, and then be sprayed to the outside of the mesh filter 104 through the nozzle 201c, so that the mesh filter 104 can be backwashed, and the impurities attached to the inside of the mesh filter 104 and its inner wall can be separated. The liquid sprayed from the nozzle 201c will impact the force plate 201d and push the force plate 201d, so that the mesh filter 104 can be driven to rotate through the force plate 201d, and then different positions of the mesh filter 104 can be cleaned, thereby ensuring that the mesh filter 104 is thoroughly unblocked.

[0056] During the cleaning process of the mesh filter 104, due to the small diameter of the sewage pipe 201e, the liquid is discharged slowly, and the water level inside the pipe 102 rises. When the water level contacts the floating block 205a, it will drive the floating block 205a and the squeezing rod 205b to move upward, so that the squeezing rod 205b approaches the force-bearing groove 204b-1 and squeezes the inner wall of the force-bearing groove 204b-1. Through the cooperation of the two, the card block 204b is driven to move, so that the card block 204b is separated from the bottom of the baffle 202b, thereby releasing the restriction on the baffle 202b. At this time, the baffle 202b can rotate downward under the pressure of the water flow, thereby stopping the cleaning work and allowing the mesh filter 104 to filter the liquid normally. At this time, the nutrient solution can be transported to the inside of the pipe 102 through the water fertilizer machine 106.

[0057] When the baffle 202b rotates downward, the connecting column 203c can push the intercepting plate 203b to rotate downward, so that the intercepting plate 203b can be opened downward and the filtered liquid can flow downward.

[0058] When the connecting column 203c moves downward, it will drive the pull rope 206d to move, and the pull rope 206d will drive the plug plate 206b to move into the fixed frame 206a. At this time, the plug plate 206b will block the drain pipe 201e to prevent the liquid from flowing out through the drain pipe 201e when flowing into the mesh filter 104, thereby causing liquid waste.

[0059] At the same time, when the baffle 202b is rotated downward to open, the sealing sleeve 207 is driven downward by the connecting rod 208, and the inlet of the diverter tube 201a is blocked by the sealing sleeve 207 to prevent the liquid from entering the inside of the diverter tube 201a at this time.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. 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.
