Description

Technical Field

[0001] The invention relates to the technical field of soilless cultivation, and more specifically to an automatic water and fertilizer system for soilless cultivation of vegetables. Background Art

[0002] Soilless cultivation refers to a cultivation method that uses water, peat, forest leaf mold, vermiculite and other media as the substrate for the plant roots to fix the plants, so that the plant roots can directly contact the nutrient solution. Since crops are cultivated with nutrient solution instead of natural soil, it is called soilless cultivation. It also includes hydroponics, substrate cultivation, rock wool cultivation, coconut bran cultivation, aerosol cultivation, etc. It is a cultivation technology that uses nutrient solution containing essential elements for crop growth and development to provide nutrition without using natural soil, so that crops can complete the entire life cycle normally.

[0003] In soilless cultivation, water and fertilizer are needed for irrigation and fertilization. Water and fertilizer equipment needs to use a pressure system or natural terrain drop to mix soluble solid or liquid fertilizers with irrigation water according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type.

[0004] The current water-free cultivation water-fertilizer system applies water and fertilizer to plants when in use, but the current water-fertilizer system does not automatically choose to add water or water-fertilizer separately, so it is not smart enough when in use;

[0005] The water-fertilizer system needs to mix water with multiple fertilizers. The promotion effect between fertilizers, also called synergistic effect, means that when two or more fertilizers are applied at the same time, they can promote each other's absorption and utilization, thereby improving the utilization efficiency of the fertilizers. However, fertilizers are easy to clump together. When mixing clumps of fertilizers with water, it cannot be guaranteed that the fertilizers and water are mixed evenly, which makes the final water-fertilizer effect poor. When mixing fertilizers with water and adding them into the mixing drum, since the water enters at the water inlet pipe, it takes a long time for the water to flow to various places inside the mixing drum, thereby reducing the efficiency of stirring and mixing.

[0030] In the embodiment of the present application, when the first switch 4 is turned on and the second switch 5 and the third switch 6 are turned off, water flows directly in the water flow branch pipe 2, so the dripping tube 9 only discharges water. When the first switch 4 is turned off and the second switch 5 and the third switch 6 are turned on, the water in the water flow branch pipe 2 enters the water-fertilizer mixing mechanism 8 through the first connecting pipe 501. The water is mixed with the fertilizer to become water-fertilizer, and then returns to the water flow branch pipe 2 through the second connecting pipe 601. At this time, the dripping tube 9 discharges the water-fertilizer. In addition, when the water flow main pipe 1 and the water flow branch pipe 2 of the present application are supplying water or water-fertilizer, the automatic watering device 3 can perform intelligent control of the flow rate, making the present application more intelligent and easy to adjust when in use.

The inside of the feeding block 703 is provided with an avoidance groove for the outer rotating ring 707 to move and for the fertilizer to pass through. The side of the output shaft 705 away from the servo motor 704 is movably connected with a reversing assembly 708. The bottom end of the fertilizer box 701 is fixedly connected with a feeding frame 710, and the top of the feeding frame 710 is fixedly connected with an inclined frame 709. The top of the inclined frame 709 is provided with an inclined surface, and the top of the sealing cover 702 is provided with an inclined surface inclined toward the center. The top of the feeding frame 710 is square, and the bottom of the feeding frame 710 is round.

[0032] In the embodiment of the present application, after opening the sealing cover 702, the fertilizer can be directly added to the discharge block 703. The top of the discharge block 703 is inclined inward, so the fertilizer will automatically fall on the outer rotating ring 707, and fall after being broken up by the inner rotating ring 706 and the outer rotating ring 707. In addition, it should be noted that multiple groups of outer rotating rings 707 are arranged on the side of the output shaft 705, and the outer rotating rings 707 are in contact with each other. The combined length of the multiple groups of outer rotating rings 707 is the same as the internal length of the fertilizer box 701. The broken fertilizer will fall into the inclined frame 709 and the discharge frame 710. The top of the inclined frame 709 has an inclined surface to facilitate the falling of the fertilizer, and the upper and lower sides of the discharge frame 710 are in the direction and the lower side is circular. The discharge frame 710 can smoothly connect the fertilizer box 701 and the mixing drum 801 below, so that the operation of the present application is more stable.

[0033] Reference Figure 6 as well as Figure 7 The reversing assembly 708 includes a fixed sealing cylinder 7081, the interior of the sealing cylinder 7081 is fixedly connected to a limit ring 7082, the side of the output shaft 705 close to the sealing cylinder 7081 is fixedly connected to an output gear 7083, the top of the output gear 7083 is meshed with a connecting gear 7084, the top of the connecting gear 7084 is meshed with a gear ring 7085, the side of the gear ring 7085 close to the sealing cylinder 7081 is provided with a sliding groove matched with the limit ring 7082, the side of the gear ring 7085 away from the sealing cylinder 7081 is fixedly connected to a connecting ring 7086, and the side of the connecting ring 7086 away from the gear ring 7085 is fixedly connected to the side of the outer rotating ring 707.

[0034] In the embodiment of the present application, when the output shaft 705 rotates, it drives the output gear 7083 to rotate. When the output gear 7083 rotates, it drives the gear ring 7085 to rotate through the connecting gear 7084. The gear ring 7085 drives the outer rotating ring 707 to rotate in the opposite direction through the connecting ring 7086. The rotation direction of the outer rotating ring 707 is opposite to that of the inner rotating ring 706. Therefore, the fertilizer dropped on the side of the outer rotating ring 707 will be scattered by the inner rotating ring 706 and the outer rotating ring 707 rotating in the opposite direction and fall downward, thereby improving the scattering effect. The gear ring 7085 rotates on the side of the limit ring 7082, so that the gear ring 7085 rotates more smoothly. In addition, it should be noted that if Figure 7 As shown, the inner rotating ring 706 rotates with the output shaft 705 inside the outer rotating ring 707, and the outer rotating ring 707 rotates in the opposite direction to the output shaft 705, and the outer rotating ring 707 rotates with the connecting ring 7086, and the outer rotating rings 707 are fixedly connected to each other for rotation.

[0035] Reference Figure 8 and Fig. 9 The water-fertilizer mixing mechanism 8 includes a mixing drum 801 for receiving fertilizers, an external ring 804 is fixedly connected to the side of the mixing drum 801, a water flow channel 805 is provided inside the external ring 804, the water flow channel 805 is communicated with the first connecting pipe 501, an outlet pipe 806 is fixedly connected inside the external ring 804, the water flow channel 805 is connected to the outlet pipe 806, the outlet pipe 806 discharges water into the mixing drum 801, and the number of the outlet pipes 806 is twelve, and the twelve outlet pipes 806 are evenly distributed in the water flow channel 805. The water-fertilizer mixing mechanism 8 includes a rotating motor 807 that can provide power, a connecting component 808 is connected to the side of the rotating motor 807, and the connecting component 808 is supported by a supporting rod 812. The bottom end of the connecting component 808 is movably connected to a stirring shaft 809, a first blade group 810 is fixedly connected to the side of the stirring shaft 809, and a second blade group 811 is fixedly connected to the bottom end of the stirring shaft 809, the bottom end of the mixing drum 801 is fixedly connected to a conical drum 802, and the bottom end of the conical drum 802 is fixedly connected to a discharge pipe 803.

[0036] In the embodiment of the present application, when the water in the first connecting pipe 501 enters the external ring 804, it will circulate on the side of the mixing drum 801 in the water flow channel 805. At this time, when it is discharged from the twelve water outlet pipes 806, the water outlet pipes 806 will be discharged into the mixing drum 801 from various places in the mixing drum 801. The water entering the mixing drum 801 will contact the fertilizer in the mixing drum 801 at different positions, avoiding the problem of water taking a long time to contact the fertilizer when falling at a single place and wasting water. When the first blade group 810 and the second blade group 811 rotate, they stir and mix the water and fertilizer to form water-fertilizer. The water-fertilizer flows back to the water flow distribution pipe 2 through the discharge block 703 and the second connecting pipe 601 in the sealing cover 702, and is discharged through the splash pipe 9.

[0037] Reference Figure 8 and Fig. 9 The connecting component 808 includes a sealing box 8082 that can be sealed, and a rotating shaft 8081 is movably connected to the side of the sealing box 8082. The side of the rotating shaft 8081 away from the sealing box 8082 is fixedly connected to the side of the rotating motor 807. The side of the rotating shaft 8081 away from the rotating motor 807 is fixedly connected to a first bevel gear 8083, and the bottom end of the first bevel gear 8083 is meshed with a second bevel gear 8084. The interior of the second bevel gear 8084 is fixedly connected to the side of the stirring shaft 809. The first bevel gear 8083 and the second bevel gear 8084 are both located inside the sealing box 8082.

[0038] In the embodiment of the present application, when the rotating motor 807 is started, it drives the rotating shaft 8081 to rotate. The rotating shaft 8081 drives the stirring shaft 809 to rotate after being transmitted by the first bevel gear 8083 and the second bevel gear 8084. The stirring shaft 809 drives the first blade group 810 and the second blade group 811 below to rotate, and the sealing box 8082 can seal the first bevel gear 8083 and the second bevel gear 8084 to prevent them from being damaged under long-term use.

[0039] The working principle of the present invention is as follows: water flows through the main water flow pipe 1 to the eight water flow branch pipes 2. When the water enters the water flow branch pipes 2, the first switch 4 is turned on and the second switch 5 and the third switch 6 are turned off. The water flows directly in the water flow branch pipes 2, so the dripping pipe 9 only discharges water. When the first switch 4 is turned off and the second switch 5 and the third switch 6 are turned on, the water in the water flow branch pipes 2 enters the water-fertilizer mixing mechanism 8 through the first connecting pipe 501. The water is mixed with the fertilizer to become water-fertilizer, and then returns to the water flow branch pipes 2 through the second connecting pipe 601. At this time, the dripping pipe 9 discharges the water-fertilizer.

[0040] When water enters the water-fertilizer mixing mechanism 8, the sealing cover 702 is opened, and fertilizer is added to the fertilizer box 701. The fertilizer slides on the feeding block 703 and falls on the side of the outer rotating ring 707. When the servo motor 704 is started, the inner rotating ring 706 is driven to rotate through the output shaft 705. At this time, the inner rotating ring 706 rotates forward, and the output shaft 705 drives the output gear 7083 to rotate when it rotates. When the output gear 7083 rotates, it drives the gear ring 7085 to rotate through the connecting gear 7084. The gear ring 7085 drives the outer rotating ring 707 to rotate in the opposite direction through the connecting ring 7086. The outer rotating ring 707 rotates in opposite directions to the inner rotating ring 706. Therefore, the fertilizer dropped on the side of the outer rotating ring 707 will be scattered by the inner rotating ring 706 and the outer rotating ring 707 rotating in the opposite direction and then fall downward;

[0041] The fertilizer after being broken up enters the mixing drum 801 through the unloading frame 710, the water in the first connecting pipe 501 enters the external ring 804, and circulates around the side of the mixing drum 801 through the water flow channel 805, and then is discharged from the water outlet pipe 806. The water outlet pipe 806 will be discharged from various places in the mixing drum 801 into the mixing drum 801. The water entering the mixing drum 801 contacts the fertilizer in the mixing drum 801, and the rotating motor 807 starts to drive the rotating shaft 8081 to rotate. The rotating shaft 8081 drives the stirring shaft 809 to rotate after being driven by the first bevel gear 8083 and the second bevel gear 8084. The stirring shaft 809 drives the first blade group 810 and the second blade group 811 below to rotate. When the first blade group 810 and the second blade group 811 rotate, the water and fertilizer are stirred and mixed to form water-fertilizer. The water-fertilizer flows back into the water flow distribution pipe 2 through the discharge block 703 and the second connecting pipe 601 in the sealing cover 702, and is discharged through the dripping pipe 9.
