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] An intelligent nutrient solution supply device is a device that can accurately prepare and automatically supply nutrient solution according to the growth needs of plants. It includes a water and fertilizer integrated machine, which can accurately mix fertilizers and water in a certain proportion according to preset parameters and transport them to the roots of crops, ensuring that crops obtain appropriate nutrients and water, avoiding waste and environmental pollution caused by over-fertilization and over-irrigation. The water and fertilizer integrated machine intercepts and filters suspended impurities in irrigation water through a mesh filter to prevent these impurities from entering the pipeline system and fertilization device of the water and fertilizer integrated machine, avoiding clogging nozzles, drippers, and damaging components such as water pumps and valves. During long-term use of the mesh filter, it needs to be disassembled and cleaned regularly. Disassembling and cleaning the mesh filter usually requires manual operation. The staff needs to disassemble the filter from the water and fertilizer integrated machine, then carefully clean the filter screen, and reinstall it. This process is rather cumbersome. Moreover, during 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. In addition, 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 screen.

[0026] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0027] In the following description, many specific details are set forth to facilitate a thorough 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 can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other from other embodiments.

[0029] Embodiment 1

[0030] Referring to Figure 1 、 Figure 2 and Figure 7 , this is the first embodiment of the present invention. This embodiment provides an intelligent nutrient solution supply device for plant cultivation. The intelligent nutrient solution supply device for plant cultivation includes a main body assembly 100, which includes a stirring barrel 101. A stirrer is provided at the top of the stirring barrel 101 for stirring and mixing fertilizers and water inside the stirring barrel 101. A pipeline 102 is provided above the stirring barrel 101. An installation sleeve 103 is fixed on one side of the pipeline 102. One end of the pipeline 102 located inside the installation sleeve 103 is in an L - shaped form, and the end is rotatably connected to a rotating sleeve. A mesh filter 104 is provided inside the installation sleeve 103. The nutrient solution flowing out of the pipeline 102 will enter the inside of the mesh filter 104 and flow out from the outside of the mesh filter 104 and then flow into the pipeline 102 below. The mesh filter 104 filters small particles and floating substances in the water.

[0031] When the mesh filter 104 is inserted into the installation sleeve 103, it will be clamped outside the rotating sleeve and tightly fixed to the rotating sleeve. In this way, when the mesh filter 104 is subjected to a thrust force, it can rotate.

[0032] One side of the installation sleeve 103 is connected with a sealing cover by bolts. A protrusion is rotatably connected to one side of the sealing cover. When the sealing cover is fixed to the installation sleeve 103, the protrusion will be stuck inside the mesh filter 104 to block the outlet at the end of the mesh filter 104 and prevent water from flowing out through the end of the mesh filter 104.

[0033] The cleaning component 200 is disposed within the mounting sleeve 103 and includes a flushing member 201. The flushing member 201 includes a flow-dividing pipe 201a fixed to one side of the pipe 102. The other end of the flow-dividing pipe 201a penetrates into the mounting sleeve 103 and is fixed with a connecting pipe 201b. Both ends of the flow-dividing pipe 201a are in communication with the mounting sleeve 103 and the connecting pipe 201b respectively. Nozzles 201c are provided on the connecting pipe 201b. The number of the nozzles 201c is multiple and they are evenly distributed in a straight line on one side of the connecting pipe 201b. The nozzles 201c are inclined towards one side of the mesh filter 104. A force-receiving plate 201d is fixed to the outside of the mesh filter 104. The number of the force-receiving plates 201d is multiple and they are evenly distributed in a ring on the outside of the mesh filter 104.

[0034] When the nutrient solution flows from the pipe 102 into the interior of the mounting sleeve 103, it will first enter the flow-dividing pipe 201a and the connecting pipe 201b, and then be sprayed onto the outside of the mesh filter 104 through the nozzles 201c, thereby backwashing the mesh filter 104 to separate the impurities attached to the interior of the mesh filter 104 from its inner wall. Moreover, the liquid sprayed from the nozzles 201c will impact on the force-receiving plates 201d and push the force-receiving plates 201d, thereby driving the mesh filter 104 to rotate through the force-receiving plates 201d, and further cleaning different positions of the mesh filter 104, and thus ensuring thorough dredging of the mesh filter 104.

[0035] A sewage discharge pipe 201e is fixed to one side of the pipe 102. The other end of the sewage discharge pipe 201e penetrates to the outside of the mounting sleeve 103. The sewage discharge pipe 201e is in communication with the pipe 102. The sewage flowing after the mesh filter 104 is cleaned will enter the sewage discharge pipe 201e and flow out through the sewage discharge pipe 201e, thereby preventing the sewage from remaining in the pipe 102 and causing blockage of the mesh filter 104 again.

[0036] The diameter of the sewage discharge pipe 201e is smaller than that of the flow-dividing pipe 201a (not shown in the figure). Therefore, the flow rate of the liquid flowing from the flow-dividing pipe 201a into the interior of the mounting sleeve 103 is greater than the discharge rate of the sewage discharge pipe 201e to the outside. Therefore, the liquid that fails to be discharged in time will accumulate in the pipe 102, and the water level inside the pipe 102 will gradually rise.

[0037] Embodiment 2

[0038] Referring to Figures 2 - 6 and Figure 8 This is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0039] Specifically, the cleaning assembly 200 further includes a first plugging member 202. The first plugging member 202 is located inside the pipeline 102 above the mounting sleeve 103. The first plugging member 202 includes a support ring 202a fixed to the inner wall of the pipeline 102. A baffle 202b is provided at the bottom of the support ring 202a. The baffle 202b is in contact with the bottom of the support ring 202a, and a sealing treatment is performed between the two. The nutrient solution flowing inside the pipeline 102 is intercepted by the baffle 202b, so that it cannot directly flow downward into the mounting sleeve 103, but will enter the shunt pipe 201a.

[0040] 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 inside the hinge seat 202d. The baffle 202b is installed and positioned through 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. An upward torsional force is applied to the baffle 202b through the torsion spring 202e, so that it can reset after being opened.

[0041] Specifically, the cleaning assembly 200 further includes a second plugging member 203. The second plugging member 203 is located inside the pipeline 102 below the mounting sleeve 103. The second plugging member 203 includes a positioning ring 203a fixed to the inner wall of the pipeline 102. An intercepting plate 203b is provided at the bottom of the positioning ring 203a. The intercepting 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 intercepting plate 203b to avoid the situation that the liquid will be discharged outward through the pipeline 102 at this time.

[0042] A connecting column 203c is provided at the top of the intercepting plate 203b. A pulley 203d is provided at 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. A positioning sleeve 203e is provided outside the pulley 203d. The number of the positioning sleeves 203e is two, which are respectively fixed to the bottom of the baffle 202b and the top of the intercepting plate 203b. The above two are connected by the connecting column 203c. The connecting column 203c is movably connected inside the bent part of the pipeline 102, and the two are in close contact.

[0043] When the baffle 202b is in a horizontal state, a pulling force will be applied to the intercepting plate 203b through the connecting column 203c, so that the intercepting plate 203b can also be in a horizontal state and intercept 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.

[0044] Specifically, the cleaning component 200 also includes a locking piece 204, which includes a support frame 204a fixed to the inner wall of the pipe 102. A block 204b is provided in the support frame 204a. The bottom side of the block 204b is inclined, and the top is in contact with the baffle 202b. The baffle 202b is limited by the block 204b so that it cannot rotate downward when subjected to the pressure of the liquid, thereby blocking and intercepting the liquid.

[0045] 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 fit upward 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.

[0046] 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.

[0047] During the cleaning process of the mesh filter 104, since the diameter of the sewage pipe 201e is small, the liquid is discharged slowly, and the water level inside the pipe 102 rises. When the water level contacts the floating block 205a, the floating block 205a and the squeezing rod 205b are driven to move upward, so that the squeezing rod 205b is close to the force groove 204b-1 and squeezes the inner wall of the force groove 204b-1. The two cooperate to drive the block 204b to move, so that the 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.

[0048] The buoyancy of the floating block 205a is relatively large and can stably overcome the elastic force of the first spring 204c.

[0049] 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.

[0050] Specifically, the cleaning component 200 further includes an intercepting member 206. The intercepting member 206 includes a fixing frame 206a fixed on the sewage discharge pipe 201e. An insertion plate 206b is inserted into the fixing frame 206a. The insertion plate 206b is movably connected within the fixing frame 206a. A guide wheel 206c is arranged on one side of the fixing frame 206a. A pulling rope 206d is wound around the outer side of the guide wheel 206c. The guide wheel 206c is used for guiding and positioning the pulling rope 206d. Both ends of the pulling rope 206d are respectively fixed to the insertion plate 206b and the connecting column 203c.

[0051] When the baffle 202b opens downward and drives the connecting column 203c to move downward, the connecting column 203c will drive the pulling rope 206d to move, and drive the insertion plate 206b to move into the fixing frame 206a through the pulling rope 206d. At this time, the sewage discharge pipe 201e is blocked by the insertion plate 206b, so as to prevent the liquid from flowing out through the sewage discharge pipe 201e when flowing into the internal of the mesh filter 104, thus avoiding the situation of liquid waste.

[0052] Embodiment 3

[0053] Refer to Figures 1 - 8 , which is the third embodiment of the present invention. This embodiment is based on the first two embodiments.

[0054] Specifically, a stabilizing block 206e is fixed on one side of the fixing frame 206a. A stabilizing column 206f is fixed on one side of the stabilizing block 206e. A connecting plate 206g is fixed on one side of the insertion plate 206b. The stabilizing column 206f is movably connected within the connecting plate 206g. A second spring 206h is sleeved on the outer side of the stabilizing column 206f. Both 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 pulling rope 206d, a thrust is applied to the connecting plate 206g through the second spring 206h, and the insertion plate 206b is driven to move out of the fixing frame 206a through the connecting plate 206g, so as to release the blockage of the sewage discharge pipe 201e.

[0055] Specifically, a sealing sleeve 207 is arranged within the pipeline 102 and above the shunt pipe 201a. The sealing sleeve 207 is annular and is in close fit with the inner wall of the pipeline 102. The sealing sleeve 207 is above the inlet of the shunt pipe 201a. A connecting rod 208 is rotatably connected within the sealing sleeve 207. The bottom end of the connecting rod 208 is hinged to the baffle 202b. When the baffle 202b rotates downward to open, the sealing sleeve 207 will be driven to move downward through the connecting rod 208, and the inlet of the shunt pipe 201a is blocked by the sealing sleeve 207, so as to prevent the liquid from entering the internal of the shunt pipe 201a at this time.

[0056] Specifically, a centrifugal filter 105 is provided on the pipeline 102. The centrifugal filter 105 is used to filter large and small particles in water. A water-fertilizer machine 106 is provided on one side of the stirring barrel 101. The water-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, ensuring that crops obtain appropriate nutrients and water, avoiding waste and environmental pollution caused by over-fertilization and over-irrigation. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0057] Specifically, a drain pipe 107 is provided on one side of the mounting sleeve 103. A valve is provided on the drain pipe 107. The drain pipe 107 can discharge the residual sewage inside the mounting sleeve 103 to the outside.

[0058] During use, under the control of the water-fertilizer machine 106, the nutrient solution inside the stirring barrel 101 is temporarily not allowed to enter the pipeline 102. At this time, only the filtered water in the pipeline 102 flows inward into the mounting sleeve 103. The water flow will first enter the shunt pipe 201a and the connecting pipe 201b, and then be sprayed onto 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. Moreover, the liquid sprayed by the nozzle 201c will impact on the force-bearing plate 201d and push the force-bearing plate 201d. In this way, the mesh filter 104 can be driven to rotate by the force-bearing plate 201d, and then different positions of the mesh filter 104 can be cleaned, and thus it can be ensured that the mesh filter 104 is thoroughly dredged.

[0059] During the cleaning process of the mesh filter 104, since the diameter of the sewage discharge pipe 201e is small, the speed of liquid discharge is slow, and the water level inside the pipeline 102 rises. When the water level contacts the floating block 205a, it will drive the floating block 205a and the extrusion rod 205b to move upward, making the extrusion rod 205b approach the inner wall of the force-bearing groove 204b-1 and extruding the inner wall of the force-bearing groove 204b-1. Through the cooperation of the two, the clamping block 204b is driven to move, separating the clamping block 204b 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 enabling the mesh filter 104 to normally filter the liquid. At this time, the nutrient solution can be transported into the pipeline 102 through the water-fertilizer machine 106.

[0060] When the baffle 202b rotates downward, the intercepting plate 203b can be pushed to rotate downward through the connecting column 203c, thereby enabling the intercepting plate 203b to open downward and allowing the filtered liquid to flow downward.

[0061] When the connecting column 203c moves downward, it will drive the pulling rope 206d to move, and drive the plug board 206b to move into the fixed frame 206a through the pulling rope 206d. At this time, the sewage pipe 201e is blocked by the plug board 206b, so as to prevent the liquid from flowing out through the sewage pipe 201e when flowing into the internal of the mesh filter 104, thus avoiding the situation of liquid waste.

[0062] At the same time, when the baffle 202b rotates downward to open, it will drive the sealing sleeve 207 to move downward through the connecting rod 208, and block the inlet of the shunt pipe 201a through the sealing sleeve 207, so as to prevent the liquid from entering the internal of the shunt pipe 201a at this time.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
