DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0022] Please refer to Figs. 1 to 4 The slow-release fertilizer release rate measuring device in the embodiment comprises a measuring tank 1 and a filter box 16, and the outside of the measuring tank 1 is provided with a timing detection device.
[0023] The timing detection device comprises an equipment rack 2 fixedly installed on the measuring tank 1, a servo motor 3 and a data recording device 4 fixedly connected to the top of the equipment rack 2, a timing starter 5 fixedly connected to the top of the servo motor 3, a lead screw 6 fixedly connected to the output shaft of the servo motor 3, a lifting plate 7 threadedly connected to the outer surface of the lead screw 6, a movable rod 8 fixedly connected to the inner side of the equipment rack 2, a nutrient concentration detector 9 fixedly connected to the bottom of the lifting plate 7, a heating pipe 10 fixedly installed in the inside of the measuring tank 1, a controller 11 and a temperature sensor 12 fixedly connected to the outer surface of the measuring tank 1. When in use, the worker first needs to pour clean water into the inside of the measuring tank 1, then put in the slow-release fertilizer, and set the starting interval time of the servo motor 3 in advance through the timing starter 5. During this period, the heating pipe 10 can heat the clean water, and the temperature sensor 12 can monitor the water temperature, so that the slow-release fertilizer is soaked at a specific temperature.
[0024] When the nutrient concentration needs to be detected, the servo motor 3 will drive the lead screw 6 to rotate clockwise continuously, so that, under the sliding limiting action of the movable rod 8, the lifting plate 7 drives the nutrient concentration detector 9 to move vertically downward continuously, until the nutrient concentration detector 9 is inserted into the clean water in the inside of the measuring tank 1, so that the nutrient concentration contained in the clean water is detected through the nutrient concentration detector 9, and the nutrient concentration data is transmitted to the data recording device 4 for display, thereby facilitating the worker to observe and compare finally.
[0025] When the nutrient concentration detector 9 completes the detection, the servo motor 3 will drive the lead screw 6 to rotate counterclockwise continuously, so that the lifting plate 7 drives the nutrient concentration detector 9 to move vertically upward continuously, until the nutrient concentration detector 9 is pulled out of the clean water in the inside of the measuring tank 1, and then waits for the next detection.
[0026] It should be noted that the inside of the measuring tank 1 is provided with clean water, and the lifting plate 7 is slidably connected with the movable rod 8.
[0027] It should be understood that a discharge pipe 13 is fixedly connected to the bottom of the measuring tank 1, a one-way valve is installed on the outside of the discharge pipe 13, and columns 14 are fixedly connected around the bottom of the measuring tank 1, with a base plate 15 fixedly connected to the bottom of the columns 14.
[0028] The filter box 16 is placed on top of the base plate 15, and the filter screen 17 is fixedly connected to the inside of the filter box 16. By setting the filter box 16 and the filter screen 17, the clean water containing slow-release fertilizer discharged through the discharge pipe 13 can be separated and filtered, so that the staff can process the water and fertilizer separately.
[0029] Meanwhile, a drain pipe 18 is fixedly installed on the left side of the filter box 16, and a pipe support 19 is fixedly connected to the top of the base plate 15. By setting the drain pipe 18, the water inside the filter box 16 can be continuously discharged to the outside.
[0030] In addition, the discharge pipe 18 passes through the pipe support 19, and the top of the pipe support 19 is threaded with a positioning bolt for pressing against the discharge pipe 18. By setting the pipe support 19, the discharge pipe 18 can be supported and limited, thereby preventing the discharge pipe 18 from moving randomly.
[0031] The working principle of the above embodiments is as follows:
[0032] In operation, the operator first pours clean water into the testing tank 1, then adds controlled-release fertilizer. The start interval of the servo motor 3 is pre-set using the timer starter 5. During this time, the heating element 10 heats the water, and the temperature sensor 12 monitors the water temperature, ensuring the controlled-release fertilizer is soaked at a specific temperature. When nutrient concentration needs to be tested, the servo motor 3 drives the lead screw 6 to rotate clockwise. Under the sliding limit action of the movable rod 8, the lifting plate 7 moves the nutrient concentration detector 9 vertically downwards until it is inserted into the water inside the testing tank 1. The nutrient concentration detector 9 then detects the nutrient concentration in the water and transmits the data to the data recording device 4 for display, facilitating observation and comparison by the operator. After the nutrient concentration detector 9 completes its test, the servo motor 3 drives the lead screw 6 to rotate counterclockwise, causing the lifting plate 7 to move the nutrient concentration detector 9 vertically upwards until it is removed from the water inside the testing tank 1, ready for the next test.
[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
