Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and more specifically, to a fertilization device for greenhouses. Background Technology

[0002] In modern agricultural production, especially in greenhouse cultivation, reasonable water and fertilizer management is one of the key factors in improving crop yield and quality. With the continuous development of smart agricultural technology, precision fertilization systems have gradually become an important part of farmland management. However, most existing fertilization systems lack effective means of regulating water and fertilizer flow. Farmers often face the problem of excessive or insufficient flow in actual operation. Unstable flow can lead to uneven fertilizer concentration, or even fertilizer waste or insufficient crop nutrition. Therefore, how to achieve precise regulation of water and fertilizer flow has become an urgent need to improve greenhouse cultivation efficiency and the healthy growth of crops.

[0003] Traditional fertilization devices mostly rely on simple flow control methods, lacking real-time monitoring and automatic adjustment functions for water and fertilizer flow. This leads to operators needing to make frequent manual adjustments. Under complex crop needs and environmental changes, this manual control method is not only cumbersome but also prone to errors, making it difficult to ensure the accuracy of water and fertilizer supply. Especially when crops at different growth stages require different amounts of water and fertilizer, traditional fertilization systems struggle to adjust in a timely manner according to the actual needs of the crops, affecting crop growth and production efficiency.

The positioning disc is fixed at the bottom end of the rotating sleeve. Multiple sets of positioning grooves are distributed on the inner wall of the locking sleeve.

[0009] The present invention is further configured such that a purification box is installed at the top of the mixing box, and a filter plate is installed inside the purification box. This design effectively filters impurities and debris by installing the purification box and the filter plate, ensuring the quality of the mixed water and fertilizer, and avoiding the impact of impurities on the spraying effect or the normal operation of the equipment.

[0010] The present invention is further provided that a partition is fixedly provided inside the purification box.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a fertilization device for greenhouses, which has the following features:

[0017] Beneficial effects:

[0018] 1. The fertilization mechanism, equipped with a support plate, a diversion pipe, an output pipe, and nozzles, can evenly distribute the mixed water and fertilizer to various areas within the greenhouse. The diversion pipe is fixed to the support plate and connected to the output pipe, ensuring a stable flow of water and fertilizer to the two sets of nozzles. This guarantees the uniformity and coverage of fertilization. Through the multi-set distribution design of the nozzles, water and fertilizer can be accurately sprayed onto the crop roots, avoiding fertilizer waste and promoting healthy crop growth, thereby improving fertilization efficiency and crop nutrient absorption rate.

[0019] 2. The adjustment mechanism adopts a design including a rotating sleeve, transmission rod, sliding sleeve, and sealing rod, which can precisely adjust the water and fertilizer flow rate. By rotating the rotating sleeve, the connecting plate and transmission rod are driven to rotate, which in turn drives the transmission sleeve and sliding sleeve to move. The movement of the sliding sleeve changes the number of holes blocked by the sealing rod, thereby realizing the adjustment of the water and fertilizer flow space and precise control of the flow rate. This adjustment method is not only convenient to operate, but also can be adjusted in real time according to the needs of different growth stages of crops, improving the accuracy of fertilization and avoiding fertilizer waste caused by uneven flow or improper adjustment.

[0020] 3. The mixing mechanism achieves efficient water and fertilizer mixing through the coordinated action of a reducer, motor, central rod, and spiral plates. The motor drives the reducer, which in turn drives the central rod to rotate. The central rod then drives multiple spiral plates to rotate at high speed, thoroughly mixing water and fertilizer to ensure a consistent water-fertilizer ratio and achieve the desired fertilization effect. The multi-group design of the spiral plates further improves mixing efficiency, ensuring that every part of the water and fertilizer is fully mixed and guaranteeing the uniformity of water and fertilizer concentration during spraying. This design makes the entire fertilization process more efficient and precise, reducing the uneven distribution of water and fertilizer or fertilizer accumulation that may occur in traditional fertilization, thereby improving fertilization effect and crop yield.

The positioning disk 21 is fixed at the bottom of the rotating sleeve 7. The positioning groove 22 is provided with multiple sets distributed on the inner wall of the locking sleeve 20.

[0032] A purification box 23 is installed at the top of the mixing box 1, and a filter plate 24 is installed inside the purification box 23. By setting the purification box 23 and installing the filter plate 24 at the top of the mixing box 1, impurities in the water and fertilizer can be effectively removed, ensuring the purity of the mixed water and fertilizer and preventing impurities from entering the nozzle or affecting the fertilization efficiency.

[0033] The purification box 23 is fixedly equipped with a partition 25. The partition 25 can divide or evenly distribute the water flow in the purification box 23, improve the filtration effect of the water flow, ensure that impurities are filtered out more efficiently, and avoid accumulation or blockage.

[0035] The lengths of the multiple sealing rods 13 are all set to be different. The sealing rods 13 of different lengths can finely adjust the control of water and fertilizer flow as needed, flexibly meet the water and fertilizer requirements of different crop growth stages, avoid excessive or insufficient fertilizer waste, and improve fertilization efficiency.

[0036] The top of the multiple sealing rods 13 and the outer side of the through hole 14 are all provided with rounded corners. The rounded corner design of the top of the sealing rods 13 and the outer side of the through hole 14 reduces the resistance and friction of water flow, ensuring that the water and fertilizer flow is more stable and uniform, avoiding flow fluctuations, improving the working efficiency of the equipment and extending its service life.

[0037] The mixing chamber 1 is equipped with a mixing mechanism, which includes a reducer 28, a motor 29, a central rod 30, and a spiral plate 31. The reducer 28 is fixed to the outer wall of the mixing chamber 1, the motor 29 is fixed to the outer wall of the reducer 28 and its output end is connected to the input end of the reducer 28, the central rod 30 rotates inside the mixing chamber 1 and is connected to the output end of the reducer 28, and multiple sets of spiral plates 31 are installed on the outer wall of the central rod 30.

[0038] In this embodiment, water is filtered and purified by filter plate 24 and then flows into mixing tank 1 to mix with fertilizer. Motor 29 is started to drive reducer 28, which in turn drives center rod 30 to rotate. Center rod 30 drives multiple sets of spiral plates 31 to mix water and fertilizer. The mixture is then delivered through diversion pipe 3 to two sets of output pipes 4 and then flows out through nozzle 5 for fertilization. When the flow rate of water and fertilizer needs to be adjusted, rotating sleeve 7 drives transmission rod 9 to rotate via connecting plate 8, engaging with transmission sleeve 10 through a threaded connection. This causes transmission sleeve 10 to drive sliding sleeve 11 along the transmission... The moving rod 9 moves with multiple sets of multi-guide bars 26, thereby changing the number of sealing rods 13 blocking the through holes 14, thus controlling the flow rate by adjusting the flow of water and fertilizer. Then, the rotating sleeve 15 rotates to drive the gear ring 16 to rotate and mesh with multiple sets of gears 19, thereby driving multiple sets of threaded sleeves 17 to engage with the screws 18. This causes the multiple sets of screws 18 to move along the threaded sleeves 17 to push the locking sleeve 20, causing the positioning grooves 22 set on the inner wall of the multiple sets to abut against the protrusions on the outer wall of the positioning disk 21, thereby positioning and limiting the rotating sleeve 7.

[0039] In summary, during the use or operation of the entire equipment: water is filtered and purified by the filter plate 24 and then flows into the mixing tank 1 to mix with fertilizer. The motor 29 is started to drive the reducer 28, which in turn drives the central rod 30 to rotate. The central rod 30 drives multiple sets of spiral plates 31 to mix the water and fertilizer. The mixture is then delivered through the diversion pipe 3 to two sets of output pipes 4 and then flows out through the nozzles 5 for fertilization. When it is necessary to adjust the flow rate of water and fertilizer, the rotating sleeve 7 drives the transmission rod 9 to rotate through the connecting plate 8, which engages with the transmission sleeve 10 through a threaded connection. This causes the transmission sleeve 10 to drive the sliding sleeve. 11 moves along the transmission rod 9 and multiple sets of multi-guide bars 26, thereby changing the number of sealing rods 13 blocking the through holes 14, thereby controlling the flow rate by adjusting the flow of water and fertilizer. Then, the rotating sleeve 15 rotates to drive the gear ring 16 to rotate and mesh with multiple sets of gears 19, thereby driving multiple sets of threaded sleeves 17 to engage with the screws 18, so that the multiple sets of screws 18 move along the threaded sleeves 17 to push the locking sleeve 20, so that the positioning grooves 22 set on the inner wall of the multiple sets abut against the protrusions on the outer wall of the positioning disk 21, thereby positioning and limiting the rotating sleeve 7.
