Description

Technical Field

[0001] This application relates to the technical field of agricultural applications, and particularly relates to an integrated watering and fertilizing device for a greenhouse. Background Art

[0002] A greenhouse is an important facility in agricultural production for protecting the growth environment of crops. By covering materials and structural design, controllable temperature, humidity, light, etc. conditions are created to achieve off-season planting, increase yields or cultivate special crops. Its core function is to provide a relatively enclosed growth space for crops, avoiding the extreme influence of natural climate. At the same time, through artificial intervention, such as ventilation, heat preservation, irrigation, fertilization, etc., environmental parameters are optimized to meet the growth needs of crops. Greenhouses are widely used in the planting of vegetables, fruits, flowers, seedlings, etc. Especially in winter or under bad weather conditions, they can effectively extend the production cycle and improve economic benefits. Modern greenhouses often combine intelligent technologies to achieve precise management, further improving resource utilization rate and crop quality. Vegetable greenhouse planting is a common way of modern vegetable planting. It uses a greenhouse covered with plastic film to plant vegetables, and artificially creates a suitable environment for vegetable growth, and artificially adjusts the production season of vegetables according to market needs.

[0003] For the parameters of the water-fertilizer ratio, irrigation time, etc. of the greenhouse watering and fertilizing device, precise settings need to be made according to crop types, soil moisture and climate conditions. However, in the existing process of greenhouse watering and fertilizing, the mixing of water and fertilizer is usually carried out by experience. During the fertilization process, uneven fertilization or water resource waste may occur. Secondly, when the existing device fertilizes, it may cause the fertilizer particles not to completely dissolve in water, resulting in too high local concentration or caking, thus blocking the drip irrigation system and affecting the normal use of the watering and fertilizing device. Summary of the Invention

[0004] This application proposes an integrated watering and fertilizing device for a greenhouse, which has the advantage of quantitative fertilization to solve the problem of uneven fertilization.

[0005] To achieve the above object, this application adopts the following technical solution: An integrated watering and fertilizing device for a greenhouse, including a greenhouse main body. One side of the greenhouse main body is provided with a water storage tank. One end of a first connecting pipe is fixedly connected to one side of the water storage tank. The other end of the first connecting pipe is fixedly connected to a filter. One end of a communicating pipe is fixedly connected to the top of the filter. A quantitative component is arranged inside the communicating pipe; The other end of the communicating pipe is fixedly connected to a mixing tank. A U-shaped pipe is fixedly connected to the bottom of the communicating pipe. Both ends of the U-shaped pipe are communicated with the communicating pipe. A stirring component is arranged inside the mixing tank; A first connecting block is arranged inside the mixing tank. An adjusting component is arranged at the bottom of the first connecting block; One side of the mixing box is fixedly connected with a drip irrigation pipe, and the top of the drip irrigation pipe is fixedly connected with a pump. The pump is arranged in the middle of the greenhouse main body and the mixing box. As described above, when working, the materials inside the storage cylinder can be circulated into the mixing box through the feed pipe and the communicating pipe. After being processed by the metering component and the stirring component, the plants inside the greenhouse can be watered and fertilized through the drip irrigation pipe.

[0006] Preferably, two groups of shunt pipes are fixedly connected to both sides of the communicating pipe. Both ends of the two groups of shunt pipes are communicated with the communicating pipe. The middle parts of the lower surfaces of the two groups of shunt pipes are fixedly connected with feed pipes. The bottoms of the two feed pipes are provided with storage cylinders. As described above, when working, two kinds of fertilizers can be simultaneously sucked through the two feed pipes. Because some fertilizers will precipitate when the concentration is high, they must be separately configured with two mother liquid barrels.

[0007] Preferably, the metering component includes a hinge plate, which is fixedly connected to one side inside the mixing box. One side of the hinge plate is fixedly connected with a hinge column. The first connecting block is hinged to the hinge column. A connecting column is fixedly sleeved inside the first connecting block. One end of the connecting column is fixedly connected with a metering column, and the metering column is slidably connected to the inside of the communicating pipe. As described above, when working, the U-shaped pipe and the connecting column can be blocked by the movement of the connecting column to achieve quantitative mixing.

[0008] Preferably, the adjusting component includes a rotating block, which is rotatably connected to the bottom of the first connecting block. One side of the rotating block is fixedly connected with a baffle. One side of the rotating block is provided with an adjusting block. The rotating block and the baffle are penetrated by a locking bolt, and the rotating block and the adjusting block are connected by the locking bolt. One side of the rotating block is fixedly connected with a first connecting rod, and one end of the first connecting rod is fixedly connected with a floating ball. The top of the rotating block is fixedly connected with a swinging block, and the swinging block is slidably connected to the inside of the first connecting block. As described above, when working, the rotating block can be driven to rotate by rotating the adjusting block, so as to drive the angle of the included angle between the first connecting rod and the first connecting block to be adjusted.

[0009] Preferably, the adjusting component includes a driving motor, which is fixedly connected to the top of the mixing box. The output end of the driving motor is fixedly connected with a first rotating shaft. The outside of the first rotating shaft is fixedly connected with a bearing sleeve. The outside of the bearing sleeve is movably sleeved with a second connecting block, and the second connecting block is fixedly connected with the greenhouse main body. The outside of the bottom of the first rotating shaft is fixedly sleeved with a driving gear. As described above, when working, the driving gear is used as a driving part to drive the driven gear to rotate.

[0010] Preferably, the adjusting assembly further includes two driven gears. The two driven gears are both arranged on both sides of the driving gear. The two driven gears are both meshed with the driving gear. A second rotating shaft is fixedly sleeved in the middle of each of the two driven gears. Stirring rods are fixedly connected to the outer sides of the two second rotating shafts. With the above structure, during operation, the rotation of the driven gears drives the stirring rods to stir the internal fertilizer and water, enabling better mixing.

[0011] Preferably, the adjusting assembly includes multiple second connecting rods. The multiple second connecting rods are all fixedly connected to the outer side of the bearing sleeve. A toothed ring is fixedly connected to the bottom of the multiple second connecting rods. Third connecting blocks are arranged at the bottoms of the two driven gears. With the above structure, during operation, the rotation of the bearing sleeve drives the second connecting rods to rotate, thereby driving the toothed ring to mesh with the driven gears for reverse stirring.

[0012] Preferably, a first mounting plate is fixedly connected to the inside of the mixing tank. A second mounting plate is fixedly connected to one side inside the mixing tank. The first mounting plate and the second mounting plate are fixedly connected. The two third connecting blocks are both fixedly connected to the top of the second mounting plate. A pressure sensing plate is fixedly clamped inside the first mounting plate. With the above structure, during operation, after the floating ball rises and contacts the pressure sensing plate, the driving motor is started.

[0013] Preferably, the two stirring rods are symmetrically arranged. The second rotating shaft is rotatably connected to the second mounting plate.

[0014] Preferably, the position of the pressure sensing plate corresponds to that of the floating ball. After the floating ball rises to a certain position, the floating ball will abut against the bottom of the pressure sensing plate. With the above structure, during operation, due to the corresponding positions of the pressure sensing plate and the floating ball, the floating ball can better contact the pressure sensing plate when it rises.

[0015] The beneficial effects of the embodiments of the present disclosure are as follows: 1. In the present invention, by continuously pumping water into the mixing tank, the floating ball will float due to buoyancy. After the floating ball floats, since the first connecting rod and the first connecting block are fixed by a locking bolt, and since the first connecting block is hinged to the hinge column, when one end of the floating ball rises, it will push the first connecting block to move to one side. The movement of the first connecting block drives the connecting column to move, and the movement of the connecting column drives the metering column to move to block the U-shaped pipe and the communicating pipe, realizing quantitative output. It is possible to spray fertilizers as needed according to the growth requirements of crops and the soil nutrient status, avoiding waste caused by excessive fertilization, while accurately controlling the application amount and range, ensuring that each crop evenly absorbs nutrients, avoiding weak seedlings or diseases caused by uneven fertilization, and avoiding problems such as root burning and leaf burning caused by excessive fertilization.

[0016] 2. By rotating the adjusting block of the present invention, the rotation of the adjusting block drives the baffle to move, the movement of the baffle drives the rotating block to move, the movement of the rotating block drives the floating ball to move. After the floating ball is moved to a suitable position, the rotating block and the adjusting block are locked through the cooperation of the nut and the locking bolt, thereby completing the adjustment of the height of the floating ball to ensure the fixed position of the floating ball, the water level and the mixing ratio are consistent for each irrigation, improving the operation stability. At the same time, when only watering is needed, since there is no need to stir water and fertilizer at this time, the height position of the floating ball can be adjusted to control the floating ball not to contact the pressure sensing plate. When a certain amount of water is reached, irrigation can be carried out, avoiding the start of the drive motor when stirring is not required, thus generating unnecessary energy consumption.

[0017] 3. By starting the drive motor of the present invention, the bearing sleeve and the first rotating shaft rotate together. After the first rotating shaft rotates, it meshes with the two driven gears respectively, thereby driving the driven gears to rotate. The rotation of the driven gears drives the stirring rod to rotate, thereby mixing the fertilizer and water, enabling it to dissolve better in water, completely releasing the nutrients in the fertilizer, avoiding nutrient waste caused by incomplete dissolution. At the same time, the undissolved fertilizer particles may block the drip irrigation system, sprinkler or irrigation pipeline. Stirring can keep the fertilizer suspended, ensuring smooth water flow, thereby reducing the equipment cleaning frequency caused by sediment accumulation and extending the service life of the fertilization equipment. At the same time, since the rotation of the bearing sleeve drives the gear ring to rotate, and the gear ring also meshes with the driven gear after rotation, thereby driving the driven gear to rotate in the reverse direction, changing the fluid movement direction, driving the fertilizer particles at the edge and bottom to remix, eliminating the stirring blind area. During the stirring process, the fertilizer particles can be quickly dispersed through the alternating forward and reverse turbulent flow effects, avoiding local high concentration or caking, ensuring the uniformity of the fertilizer solution composition, and further improving the stirring effect.

At the same time, when only watering is needed, since there is no need to stir water and fertilizer at this time, the height position of the floating ball 21 can be adjusted to control the floating ball 21 not to contact the pressure sensing plate 36. When a certain amount of water is reached, irrigation can be carried out, avoiding the start of the drive motor 23 when stirring is not required, thus generating unnecessary energy consumption.

[0031] Among them, the adjustment component includes a driving motor 23, which is fixedly connected to the top of the mixing tank 9. The output end of the driving motor 23 is fixedly connected with a first rotating shaft 24. The outer side of the first rotating shaft 24 is fixedly connected with a bearing sleeve 25.

The rotation of the driven gears 28 drives the stirring rods 30 to rotate, so as to mix the fertilizer and water, make it better dissolve in water, fully release the nutrients in the fertilizer, avoid nutrient waste caused by incomplete dissolution, and at the same time, the undissolved fertilizer particles may block the drip irrigation system, sprinkler or irrigation pipeline. Stirring can keep the fertilizer suspended, ensure smooth water flow, thereby reducing the cleaning frequency of the equipment caused by sediment accumulation and extending the service life of the fertilization equipment; at the same time, since the rotation of the bearing sleeve 25 will drive the toothed ring 32 to rotate, and after the toothed ring 32 rotates, it will also be meshed with the driven gears 28, thereby driving the driven gears 28 to rotate in the reverse direction, so as to change the fluid movement direction, drive the fertilizer particles at the edge and bottom to be remixed, eliminate the stirring blind area, and quickly disperse the fertilizer particles through the alternating positive and negative turbulent flow effects during the stirring process, avoid local high concentration or caking, and ensure the uniformity of the fertilizer solution composition, thereby further improving the stirring effect.

After the floating ball 21 is lifted to a certain position, the floating ball 21 will abut against the bottom of the pressure induction plate 36. By making the position of the pressure induction plate 36 correspond to that of the floating ball 21, it can better contact the pressure induction plate 36 when being lifted, and the pressure induction plate 36 is electrically connected to the driving motor 23.

[0035] Working principle: Before watering and fertilizing the vegetation inside the greenhouse main body 1, the adjusting block 19 can be rotated first. The rotation of the adjusting block 19 drives the baffle 18 to move, the movement of the baffle 18 drives the rotating block 17 to move, and the movement of the rotating block 17 drives the 20 and the floating ball 21 to move. After moving the floating ball 21 to a suitable position, the rotating block 17 and the adjusting block 19 are locked through the cooperation of the nut and the locking bolt 38, so as to complete the adjustment of the height of the floating ball 21, ensure the fixed position of the floating ball, make the water level and mixing ratio consistent for each irrigation, and improve the operation stability. At the same time, when only watering is needed, since there is no need to stir water and fertilizer at this time, the height position of the floating ball 21 can be adjusted to control the floating ball 21 not to contact the pressure induction plate 36. When a certain amount of water is reached, irrigation can be carried out, avoiding the start of the driving motor 23 when stirring is not needed, thus causing unnecessary energy consumption; When fertilizing the inside of the greenhouse main body 1 is needed, at this time, water flow and materials flow into the inside of the mixing box 9 through the communicating pipe 5 together. When the water volume continues to be filled into the inside of the mixing box 9, the floating ball 21 will float due to buoyancy. After the floating ball 21 floats, since the first connecting rod 20 and the first connecting block 14 are fixed by the locking bolt 38, and since the first connecting block 14 is hinged to the hinge column 13, after one end rises, it will push the first connecting block 14 to move to one side. The movement of the first connecting block 14 drives the connecting column 15 to move, and the movement of the connecting column 15 drives the metering column 16 to move to block the U-shaped pipe 37 and the communicating pipe 5, realizing quantitative output, and then it can spray fertilizers according to the growth needs of crops and the soil nutrient status as required, avoiding waste caused by over-fertilization, accurately controlling the application amount and scope at the same time, ensuring that each crop evenly absorbs nutrients, and avoiding problems such as weak seedlings or diseases caused by uneven fertilization, and problems such as root burning and leaf burning caused by over-fertilization; When the metering column 16 blocks the U-shaped tube 37 and the connecting pipe 5, the floating ball 21 will contact the pressure sensing plate 36 at this time, thereby starting the driving motor 23 to drive the bearing sleeve 25 and the first rotating shaft 24 to rotate together. After the first rotating shaft 24 rotates, it will mesh with the two driven gears 28 respectively, thereby driving the driven gears 28 to rotate. The rotation of the driven gears 28 drives the stirring rod 30 to rotate, thereby mixing the fertilizer with water, enabling it to dissolve better in water, completely releasing the nutrients in the fertilizer, avoiding nutrient waste caused by incomplete dissolution, and at the same time, the undissolved fertilizer particles may block the drip irrigation system, sprinkler or irrigation pipeline. Stirring can keep the fertilizer suspended, ensure smooth water flow, thereby reducing the equipment cleaning frequency caused by precipitation and accumulation, and extending the service life of the fertilization equipment; at the same time, since the rotation of the bearing sleeve 25 will drive the gear ring 32 to rotate, and after the gear ring 32 rotates, it will also mesh with the driven gear 28, thereby driving the driven gear 28 to rotate in the reverse direction, thereby changing the fluid movement direction, driving the fertilizer particles at the edge and bottom to be remixed, eliminating the stirring blind area. During the stirring process, the fertilizer particles can be quickly dispersed through the positive and negative alternating turbulent flow action, avoiding local high concentration or caking, ensuring the uniformity of the fertilizer solution composition, and thus further improving the stirring effect. After the stirring is completed, the pump 10 is started to carry out drip irrigation through the drip irrigation pipe 11 to complete the work.
