Description

Technical Field

[0001] This utility model relates to the field of nutrient solution filling technology, and in particular to a quantitative filling device for plant liquid nutrient solution. Background Technology

[0002] The filling of plant liquid nutrient solution requires precise control of the filling volume based on the nutritional needs of different plant growth cycles. Therefore, high-speed quantitative filling equipment is needed to ensure the filling requirements of each bottle of nutrient solution. Existing quantitative filling equipment for plant liquid nutrient solution has problems such as inaccurate filling power transmission and single displacement detection, which makes it difficult to achieve high-precision filling. Moreover, the filling volume is easily affected by changes in the viscosity of the nutrient solution, resulting in large errors. At the same time, the traditional filling head design is unreasonable, with high resistance to liquid flow, which easily leads to residual nutrient solution and waste. It may also cause liquid splashing or container collision due to improper distance between the filling head and the container, posing safety hazards and affecting the filling stability.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a quantitative filling device for plant liquid nutrient solution, comprising: a filling piston cylinder 1, a filling control cylinder 3 fixedly installed at the middle of the top end face of the filling piston cylinder 1, a filling piston head 6 slidably connected inside the filling piston cylinder 1, a conveying pipe 2 fixedly connected to the bottom of the rear side wall of the filling piston cylinder 1, the conveying pipe 2 communicating with the internal cavity of the filling piston cylinder 1, a conveying pump 201 fixedly connected to the upper rear side of the conveying pipe 2, the inlet end of the conveying pump 201 connected to a storage tank, the upper side of the filling piston cylinder 1 slidably connected to the main body of the equipment, and lifting connecting rods 103 fixedly installed on the left and right outer side walls of the filling piston cylinder 1, the upper side of the two lifting connecting rods 103... A lifting control plate 104 is fixedly connected between them. Specifically, the filling control cylinder 3 can drive the filling piston head 6 to slide precisely inside the filling piston cylinder 1. In conjunction with the delivery pump 201, nutrient solution is delivered into the filling piston cylinder 1 through the delivery pipe 2, ensuring basic control of the nutrient solution filling volume. The lifting linkage 103 and the lifting control plate 104 provide a stable lifting support structure for the filling piston cylinder 1, allowing it to slide smoothly on the main body of the equipment. This facilitates position adjustment according to the height of the filling container, enhancing the equipment's adaptability to containers of different sizes. At the same time, it forms a linkage with the subsequent lifting control cylinder 4 to achieve automated height adjustment, improving the continuity and efficiency of the overall filling process.

[0027] The filling piston cylinder 1 has a filling head 101 fixedly connected to its bottom. The filling head 101 is conical in shape, and mounting bases 102 are fixedly connected to its front and rear outer walls. A distance sensor 7 is fixedly installed on the mounting base 102. Specifically, the conical filling head 101 at the bottom of the filling piston cylinder 1 reduces the resistance when the nutrient solution flows out, making the liquid output smoother. At the same time, it reduces the amount of residue and avoids waste of nutrient solution and blockage of the filling head 101. The distance sensor 7 is stably installed through the mounting base 102 and can detect the distance between the filling head 101 and the container to be filled in real time. After feeding the data back to the control system, it can be used in conjunction with the lifting structure to accurately adjust the height of the filling head 101, preventing the container from colliding due to being too close or the liquid from splashing due to being too far away. This improves the safety and stability of the filling process and ensures that the nutrient solution is accurately injected into the container.

[0028] The bottom telescopic end of the filling control cylinder 3 is slidably connected to the filling piston cylinder 1 and to the top center of the filling piston head 6. Two displacement sensors 601 are symmetrically installed on the top of the filling piston head 6. Specifically, the direct connection between the filling control cylinder 3 and the filling piston head 6 ensures the accuracy of power transmission and can drive the filling piston head 6 to quickly cut off the supply of nutrient solution. The two symmetrically arranged displacement sensors 601 can detect the movement distance of the piston head in real time. The accuracy of displacement data is improved through dual detection. The control system calculates the filling volume based on the cross-sectional area of ​​the piston cylinder and the displacement data to achieve high-precision quantitative control. Moreover, the symmetrical layout can avoid errors caused by the failure of a single sensor, enhance the reliability of equipment operation, and is not affected by changes in the viscosity of the nutrient solution, further improving the quantitative filling accuracy.

[0029] The main body of the equipment includes a main frame 5 and a lifting control cylinder 4. The main frame 5 is a crossbeam on the main body of the equipment. The lifting control cylinder 4 is fixedly installed at the top center of the main frame 5. The bottom telescopic end of the lifting control cylinder 4 is fixedly connected to the lifting control plate 104 between the two lifting connecting rods 103 on the upper side of the filling piston cylinder 1. The tops of the two lifting connecting rods 103 are slidably connected in the main frame 5. Specifically, the main frame 5, as a crossbeam, provides stable support for the entire filling mechanism, ensuring the structural stability of the equipment during operation. The lifting control cylinder 4, through connection with the lifting control plate 104, can drive the lifting connecting rods 103 to move the filling piston cylinder 1 along the main frame 5, realizing the automatic adjustment of the filling height. It forms a closed-loop control with the distance sensor 7 on the filling head 101, quickly responding to the height requirements of different containers. The sliding connection between the lifting connecting rods 103 and the main frame ensures the stability of the lifting process, avoids the shaking of the filling mechanism from affecting the filling accuracy, and improves the overall adaptability and adjustment accuracy of the equipment to different container sizes, thereby increasing the filling efficiency.

[0030] The specific usage and function of this embodiment are as follows:

[0031] When using this plant liquid nutrient solution quantitative filling equipment, the container to be filled is first placed below the filling head 101. The distance sensor 7 detects the distance between the filling head 101 and the container in real time and provides feedback. The lifting control cylinder 4 drives the lifting linkage 103 through the lifting control plate 104, which drives the filling piston cylinder 1 to slide along the main frame 5 of the equipment and automatically adjusts to the appropriate height for the container. Then, the delivery pump 201 delivers nutrient solution into the filling piston cylinder 1 through the delivery pipe 2. The filling control cylinder 3 drives the filling piston head 6 to slide in the cylinder. The displacement sensor 601 detects the movement distance of the piston head in real time and accurately calculates the filling volume by combining the cross-sectional area of ​​the cylinder. Finally, the quantitative nutrient solution is injected into the container through the conical filling head 101 to complete the filling operation. The entire process realizes automated adaptation and high-precision quantitative filling for containers of different specifications.

[0032] Example 2:

[0033] The distance sensor 7 is fitted with a transparent polycarbonate protective shell, which is fixed by a slot on the mounting base 102. The surface of the protective shell is covered with an anti-fog film. The protective shell and the anti-fog film can prevent the nutrient solution from splashing and contaminating the distance sensor 7, while ensuring the transmittance of detection light and adapting to the humid filling environment.
