Abstract

The application discloses an automatic water spraying device for soil fertilization, which comprises a mixing box, a water inlet, a fertilizer filling opening, a spring, an extendable supporting rod, a mixing mechanism and an adjusting mechanism. The water inlet and the fertilizer filling opening are embedded on the left side of the mixing box. The airflow generated by the rotation of the fan blade can be collected through the arc of the top cover, and the rotation of the rotating ball can compress the airflow, so that the airflow with large flow rate is sprayed from the inside of the aeration nozzle, thereby spraying the fertilizer at the bottom of the inside of the mixing box upwards, and improving the solubility of the fertilizer in the water source. When the mixed liquid is sprayed from the inside of the nozzle, the hydraulic pressure impacts the plug downwards. Under the linkage action of the linkage rod, the sliding block elastically slides downwards along the spring rod. The plug falls directly below the nozzle, disperses the mixed liquid sprayed from the inside of the nozzle, and after the water spraying is completed, the spring rod is elastically reset, the plug is reset, the soil floating is avoided from being blocked in the inside of the nozzle, and the influence on the water spraying effect of the next time is avoided.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more specifically, to an automatic water spraying device for soil fertilization. Background Technology

[0002] Soil improvement refers to the process of building a good soil body, cultivating a fertile topsoil layer, and improving soil fertility and productivity through human production activities. The basic principles of soil improvement are to combine land use with soil conservation and to combine prevention of fertility decline with soil management. During the soil improvement process, automatic watering devices can be used to automatically spray water on the soil.

[0003] However, existing automatic sprinkler systems for soil fertilization have the following shortcomings: During the automatic watering process in greenhouses, the water and fertilizer need to be mixed and sprayed out. During the mixing process, the fertilizer tends to settle to the bottom, reducing its solubility. Furthermore, the nozzles of the automatic sprinkler system impact the soil as they spray the mixture, causing soil to float up and clog the nozzles, thus reducing the watering effect of the automatic sprinkler system. Summary of the Invention

[0004] The technical solution adopted by the present invention to achieve the technical objective is: an automatic watering device for soil fertilization, the structure of which includes a slide rail, a slider, and a watering mechanism, wherein the slider is slidably installed on the slide rail and the slider is located on the top of the watering mechanism.

[0005] As a further improvement of the present invention, the water spraying mechanism includes a mixing tank, a water inlet, a fertilizer filling inlet, a spring, a telescopic support rod, a mixing mechanism, and an adjusting mechanism. The water inlet and the fertilizer filling inlet are both embedded on the left side of the mixing tank, and the slider is located on the top of the mixing tank. The inside of the mixing tank is connected to the upper end of the telescopic support rod via the spring. The mixing mechanism is installed inside the mixing tank. The upper end of the adjusting mechanism is connected through to the middle of the bottom of the mixing tank. The lower end of the telescopic support rod is connected to the adjusting mechanism. There are two springs and two telescopic support rods, respectively located at both ends of the bottom of the mixing tank and between the adjusting mechanism.

[0006] As a further improvement of the present invention, the mixing mechanism includes a motor, a stirring rod, blades, a transmission rod, and a rotating mechanism. The motor is installed at the top middle of the mixing tank, and the motor output end rotates synchronously with the upper end of the stirring rod. Blades are welded to the outside of the stirring rod. Both the stirring rod and the blades are located in the middle of the mixing tank. The lower end of the stirring rod is connected to the rotating mechanism through the transmission rod. The rotating mechanism is located at the lower end of the mixing tank. There are two transmission rods and two rotating mechanisms, which are installed symmetrically on the left and right. The transmission rods on both sides are bevel gear transmission rods, which mesh with the bevel gears at the bottom of the stirring rod.

[0007] As a further improvement of the present invention, the rotating mechanism includes a transmission gear, a rotating rod, fan blades, and an aeration mechanism. The lower end of the stirring rod is connected to the transmission gear via the transmission rod, and the transmission gear is located at the middle end of the rotating rod. Fan blades are welded to the outside of the rotating rod and are located inside the aeration mechanism. The transmission gear is a bevel gear, located at the middle end of the rotating rod at the same center, and multiple fan blades are welded to the outside of the rotating rod.

[0008] As a further improvement of the present invention, the aeration mechanism includes a top cover, a rotating ball, and an aeration nozzle. The rotating ball is provided inside the top cover, and the top cover is located outside the fan blade. An aeration nozzle is embedded on the outer end face of the top cover. The top cover has an arc-shaped structure, and multiple aeration nozzles are provided equidistantly in a ring on the outer side of the top cover. A rotating ball is matched at the lower end of each aeration nozzle.

[0009] As a further improvement of the present invention, the regulating mechanism includes a connecting pipe, a telescopic hose, a diverting mechanism, and a flow booster. The connecting pipe has a telescopic hose at its middle end and is connected between the mixing tank and the diverting mechanism. The diverting mechanism has a flow booster at its center. The telescopic hose has a pleated structure and is made of rubber, which has good resilience. The flow booster consists of a long rod and blades.

[0010] As a further improvement of the present invention, the diversion mechanism includes a diversion pipe, a nozzle, a sliding block, a spring rod, a plug, and a connecting rod. The connecting pipe connects the mixing tank and the diversion pipe. A flow booster is provided at the center of the inside of the diversion pipe. A nozzle is embedded at the lower end of the diversion pipe. A spring rod is provided inside the lower edge of the nozzle, and the spring rod passes through the inside of the sliding block with a clearance fit. The sliding block and the plug are connected by a connecting rod. The plug is located at the lower end of the nozzle. There are three or more nozzles, which are arranged in a ring at equal intervals at the bottom of the diversion pipe.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. The motor starts and drives the stirring rod and blades to rotate, initially mixing the water and fertilizer. Through the transmission rod, the transmission gear drives the rotating rod and fan blades to rotate at the bottom of the mixing tank, generating airflow. The arc shape of the top cover can collect the airflow generated by the fan blades, and after being compressed by the rotation of the rotating ball, a larger airflow is ejected from the aeration nozzle, thereby spraying the fertilizer at the bottom of the mixing tank upwards, improving the solubility of the fertilizer in the water.

[0013] 2. After the water and fertilizer are thoroughly mixed to form a mixture, it enters the connecting pipe from the mixing tank. Through the elastic extension and contraction of the telescopic hose, the height of the diversion mechanism at the bottom of the mixing tank can be automatically adjusted to regulate the height of water spraying onto the soil. After the mixture enters the diversion pipe, the flow booster is rotated by hydraulic pressure, which improves the uniformity and impact force of the mixture discharged from the diversion mechanism, thereby improving the spraying effect of the mixture on the soil.

[0014] 3. When the mixture is sprayed out from inside the nozzle, the hydraulic pressure impacts the stopper downwards. Under the action of the connecting rod, the sliding block slides elastically downwards along the spring rod. At this time, the stopper can fall directly below the nozzle, dispersing the mixture sprayed out from inside the nozzle. After the water spraying is finished, the spring rod applies elastic reset. At this time, the sliding block and the connecting rod drive the stopper to elastically reset, preventing soil from floating up and clogging inside the nozzle, thus avoiding affecting the water spraying effect of the next time.

Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings: Example

[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] The present invention provides an automatic watering device for soil fertilization, the structure of which includes a slide rail H, a slider D, and a watering mechanism S. The slider D is slidably mounted on the slide rail H and is located on the top of the watering mechanism S.

[0026] The water spraying mechanism S includes a mixing tank s5, a water inlet s7, a fertilizer filling inlet s4, a spring s8, a telescopic support rod s1, a mixing mechanism s2, and an adjusting mechanism s3. The water inlet s7 and the fertilizer filling inlet s4 are both embedded on the left side of the mixing tank s5, and the slider D is located on the top of the mixing tank s5. The interior of the mixing tank s5 is connected to the upper end of the telescopic support rod s1 via the spring s8. The mixing mechanism s2 is installed inside the mixing tank s5. The upper end of the adjusting mechanism s3 is connected to the middle of the bottom of the mixing tank s5. The lower end of the telescopic support rod s1 is connected to the adjusting mechanism s3.

[0027] Two springs s8 and two telescopic support rods s1 are provided, respectively located at both ends of the bottom of the mixing box s5 and between the adjusting mechanism s3. Through the elastic extension and contraction support of the two springs s8 and the telescopic support rods s1, the adjusting mechanism s3 can elastically rise and fall at the bottom of the mixing box s5 to adjust the height of water spraying on the soil.

[0028] The mixing mechanism s2 includes a motor s24, a stirring rod s22, blades s28, a transmission rod s26, and a rotating mechanism s21. The motor s24 is installed at the top middle of the mixing box s5, and the output end of the motor s24 rotates synchronously with the upper end of the stirring rod s22. Blades s28 are welded to the outside of the stirring rod s22. Both the stirring rod s22 and the blades s28 are located in the middle of the mixing box s5. The lower end of the stirring rod s22 is connected to the rotating mechanism s21 through the transmission rod s26, and the rotating mechanism s21 is located at the lower end of the mixing box s5.

[0029] Two transmission rods s26 and two rotating mechanisms s21 are provided, which are installed symmetrically on the left and right. The transmission rods s26 on both sides are bevel gear transmission rods, which mesh with the bevel gear at the bottom of the stirring rod s22. This allows the two rotating mechanisms s21 to rotate synchronously at the lower ends on both sides inside the mixing box s5, thus reducing the effect of fertilizer settling to the bottom inside the mixing box s5.

[0030] The rotating mechanism s21 includes a transmission gear 1c, a rotating rod 1z, a fan blade 1y, and an aeration mechanism 1b. The lower end of the stirring rod s22 is connected to the transmission gear 1c via a transmission rod s26. The transmission gear 1c is located at the middle end of the rotating rod 1z. The fan blade 1y is welded to the outside of the rotating rod 1z and is located inside the aeration mechanism 1b.

[0031] The transmission gear 1c is a bevel gear, located at the middle end of the same circle as the rotating rod 1z, and multiple fan blades 1y are welded to the outside of the rotating rod 1z. The rotating rod 1z drives the multiple fan blades 1y to rotate, generating a large airflow.

[0032] The aeration mechanism 1b includes a top cover b6, a rotating ball b3, and an aeration nozzle b8. The rotating ball b3 is provided inside the top cover b6, and the top cover b6 is located outside the fan blade 1y. The aeration nozzle b8 is embedded on the outer end face of the top cover b6.

[0033] The top cover b6 has an arc-shaped structure, and multiple aeration nozzles b8 are equidistantly arranged in a ring on the outer side of the top cover b6. Each aeration nozzle b8 is matched with a rotating ball b3 at its lower end. The arc shape of the top cover b6 can collect the airflow generated by the rotation of the fan blade 1y, and after being compressed by the rotation of the rotating ball b3, a larger airflow is ejected from the inside of the aeration nozzle b8, thereby spraying the fertilizer at the bottom of the inner side of the mixing box s5 upward, improving the solubility of the fertilizer in the water source.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, a slide rail H is installed at the top of the greenhouse. The water inlet s7 and fertilizer inlet s4 are connected to the external water and fertilizer sources, respectively. Water and fertilizer enter the mixing box s5 for mixing. A slider D drives the mixing box s5 and its lower portion to slide on the slide rail H, thus fertilizing and watering the soil inside the greenhouse. When water and fertilizer enter the mixing box s5, the motor s24 starts, driving the stirring rod s22 and blades s28 to rotate, initially mixing the water and fertilizer. Meanwhile, some... The fertilizer sinks to the bottom of the mixing tank s5. At this time, the transmission rod s26 drives the transmission gear 1c to rotate synchronously with the stirring rod s22. The transmission gear 1c drives the rotating rod 1z and the fan blade 1y to rotate inside the bottom of the mixing tank s5 to generate airflow. The arc shape of the top cover b6 can collect the airflow generated by the rotation of the fan blade 1y, and after being compressed by the rotation of the rotating ball b3, a large airflow is ejected from the aeration nozzle b8, thereby spraying the fertilizer at the bottom of the mixing tank s5 upwards and improving the solubility of the fertilizer in the water source. Example

[0036] As attached Figure 6 To be continued Figure 7 As shown:

[0037] The regulating mechanism s3 includes a connecting pipe s33, a telescopic hose s31, a diversion mechanism s39, and a flow booster s36. The connecting pipe s33 has a telescopic hose s31 at its middle end, and the connecting pipe s33 is connected between the mixing box s5 and the diversion mechanism s39. The flow booster s36 is located at the center of the diversion mechanism s39.

[0038] The telescopic hose s31 has a pleated structure and is made of rubber, which has good resilience and allows the connecting pipe s33 to extend and retract automatically. The flow booster s36 consists of a long rod and blades. When the mixed liquid enters the diversion mechanism s39, the flow booster s36 is rotated by hydraulic pressure, which improves the uniformity and impact force of the mixed liquid discharged from the diversion mechanism s39, and improves the spraying effect of the mixed liquid on the soil.

[0039] The diversion mechanism s39 includes a diversion pipe 9g, a nozzle 9z, a sliding block 9h, a spring rod 9t, a plug 9s, and a connecting rod 9v. The connecting pipe s33 connects the mixing box s5 and the diversion pipe 9g. A flow booster s36 is provided in the center of the diversion pipe 9g. The nozzle 9z is embedded in the lower end of the diversion pipe 9g. The spring rod 9t is provided in the lower edge of the nozzle 9z. The spring rod 9t passes through the sliding block 9h with a clearance fit. The sliding block 9h and the plug 9s are connected by the connecting rod 9v.

[0040] The plug 9s is located at the lower end of the nozzle 9z. There are three or more nozzles 9z, which are arranged in a ring at equal intervals at the bottom of the diversion pipe 9g. The nozzles 9z can evenly spray the mixed liquid inside the diversion pipe 9g onto the soil.

[0041] The specific usage and function of this embodiment are as follows:

[0042] In this invention, after water and fertilizer are thoroughly mixed to form a mixture, it enters the connecting pipe s33 from the mixing tank s5. Through the elastic extension and retraction of the telescopic hose s31, the height of the diversion mechanism s39 at the bottom of the mixing tank s5 can be automatically adjusted to regulate the spraying height on the soil. After the mixture enters the diversion pipe 9g, the booster s36 rotates under hydraulic pressure, improving the uniformity and impact force of the mixture discharged from the diversion mechanism s39, thus enhancing the spraying effect on the soil. Simultaneously, when the mixture is sprayed from the nozzle 9z... The hydraulic pressure impacts the stopper 9s downwards. Under the action of the connecting rod 9v, the sliding block 9h slides elastically downwards along the spring rod 9t. At this time, the stopper 9s can fall directly below the nozzle 9z, dispersing the mixture sprayed from inside the nozzle 9z and improving the comprehensiveness of water spraying on the soil. At the same time, after the water spraying is completed, the spring rod 9t applies elastic reset. At this time, the sliding block 9h and the connecting rod 9v drive the stopper 9s to elastically reset, plugging the lower end of the nozzle 9z to prevent soil from floating up and clogging inside the nozzle 9z, thus avoiding affecting the water spraying effect of the next time.
