Description

Technical Field

[0001] This utility model relates to the field of fertilization device technology, specifically a fertilization device for tomato cultivation. Background Technology

[0002] Fertilizer application devices for tomato cultivation fall under the category of auxiliary equipment for tomato cultivation in the agricultural planting field. Specifically, they involve specialized fertilizer application devices used for applying fertilizer during the growth of tomato seedlings. They are mainly used in tomato field planting scenarios to provide equipment support for nutrient supply to tomato seedlings at different growth stages, thereby assisting in fertilizer management during the tomato cultivation process.

[0003] Before the advent of this fertilization device, fertilization equipment used for tomato cultivation often required frequent manual adjustments to its placement, which not only increased labor costs but also made the fertilization process cumbersome. Furthermore, existing fertilization equipment typically lacked a stirring mechanism that activated synchronously with the equipment's movement, leading to fertilizer sedimentation when left to stand inside. This resulted in uneven fertilizer concentrations with each spray, potentially causing adverse effects on tomato growth due to excessively high or low concentrations in certain areas. In addition, the nozzles of existing equipment were mostly fixed, preventing changes in spray direction during fertilization. This easily created spray dead zones in the leaf or root areas of tomato seedlings, resulting in uneven fertilizer coverage and ultimately reducing fertilizer utilization and overall fertilization effectiveness. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fertilization device for tomato cultivation, which solves the technical problem that the spraying direction cannot be changed during fertilization, easily forming spray dead zones in the leaf or root areas of tomato seedlings, making it impossible to evenly cover the fertilizer, and ultimately reducing the utilization rate of fertilizer and the overall fertilization effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fertilization device for tomato cultivation, comprising: a base, a box body, and a first track wheel, wherein the first track wheel is disposed at the bottom of the box body and is connected to the base, and the inner cavity of the base is provided with a stirring mechanism, wherein the stirring mechanism includes a short shaft, and both sides of the short shaft are connected to second track wheels;

[0006] The short shaft is sleeved with a first conical tooth. A stirring rod is provided at the top of the first conical tooth. Both ends of the stirring rod are connected to second conical teeth. The lower second conical tooth meshes with the first conical tooth, and the upper second conical tooth meshes with a third conical tooth. A water pipe is sleeved in the inner cavity of the third conical tooth. A water collection pipe is connected to the outside of the water pipe. A nozzle is uniformly connected to the outlet end of the water collection pipe. The other end of the water pipe is connected to a pipe through a bearing. A pump body is connected to the outside of the pipe.

[0007] The pump body's inlet is connected to a bend in the pipe, which is connected to the housing. A control valve is installed on the outside of the bend. Its working principle is as follows: First, liquid fertilizer is discharged into the inner cavity of the housing. The base is placed outside the tomato seedlings. The first track wheel is activated, moving the housing outside the base. The pump body is activated to draw in the fertilizer through the bend, and then discharges it through the water pipe and nozzle. Simultaneously, as the housing moves, the second track wheel at the bottom rotates in contact with the base, which in turn drives the second conical tooth to rotate via the first conical tooth, thereby rotating the stirring rod. The rotating stirring rod agitates the fertilizer, preventing sedimentation and ensuring uniform fertilizer concentration.

[0008] At the same time, the second conical tooth at the top drives the third conical tooth to rotate, and the third conical tooth drives the water pipe, water collection pipe and nozzle to rotate, so that the nozzle can spray the leaves and roots of the tomato seedlings comprehensively and evenly during the rotation, thus improving the fertilization effect.

[0009] Preferably, track blocks are evenly distributed on the upper end of the base, and the track blocks are located outside the first track wheel and the second track wheel. The track blocks can guide and limit the movement of the first track wheel and the second track wheel, preventing the box from shifting during movement, ensuring that the first track wheel drives the box to move stably and the second track wheel rotates stably, thereby ensuring the orderly progress of mixing and spraying operations.

[0010] Preferably, an observation window is embedded on the outside of the box, and scale lines are provided on the outside of the observation window. The remaining amount of liquid fertilizer in the inner cavity of the box can be directly observed through the observation window, and the scale lines can be used to accurately control the amount of fertilizer, so as to facilitate timely replenishment of fertilizer, avoid interruption of fertilization due to insufficient fertilizer, and ensure the continuity of fertilization operation.

[0011] Preferably, a water inlet is provided on the top of the housing, and a control module is provided on the outside of the housing. The control terminal of the control module is electrically connected to the pump body and the control valve. The control module can realize automated control of the pump body's start and stop and the opening and closing degree of the control valve, thereby adjusting the fertilizer intake and spraying volume, improving the accuracy of fertilization, reducing fertilizer waste, reducing manual operation intensity, and improving work efficiency.

[0012] Preferably, a spherical bearing is fitted onto the outside of the water pipe, and the spherical bearing is connected to the outside of the housing via a bracket. The spherical bearing reduces the frictional resistance between the water pipe and the bracket when the water pipe rotates, ensuring the smooth rotation of the water pipe, water collection pipe, and nozzle, and ensuring that the nozzle can stably cover the leaves and roots of the tomato seedlings, thereby improving the uniformity of spraying.

[0013] Preferably, a sealed bearing is provided at the junction of the stirring rod and the housing. The stirring rod includes a long shaft, and a stirring arm is provided on the outside of the long shaft. The sealed bearing can prevent liquid fertilizer in the housing from leaking from the connection between the stirring rod and the housing, ensuring the airtightness of the device; the stirring arm of the stirring rod can increase the contact area with the fertilizer, enhance the stirring effect, more effectively prevent fertilizer sedimentation, ensure uniform fertilizer concentration, and improve the quality of fertilization.

[0014] Compared with the prior art, this utility model provides a fertilization device for tomato cultivation, which has the following beneficial effects:

[0015] This tomato fertilization device allows the container to move on a base placed outside the tomato seedlings via a first track wheel, eliminating the need for frequent manual adjustments, reducing labor input, and making the fertilization process more convenient. The movement of the container drives the rotation of the second track wheel at the bottom, which, through the meshing of the first and second conical teeth, rotates the stirring rod, continuously agitating the fertilizer inside the container. This prevents fertilizer from settling due to static conditions, ensuring consistent fertilizer concentration with each spray and preventing localized over- or under-concentration from negatively impacting tomato growth. Simultaneously, the meshing of the second and third conical teeth at the top drives the water pipe, water collection pipe, and nozzle to rotate synchronously. This allows the nozzle to change spray direction during the moving fertilization process, evenly covering the leaves and roots of the tomato seedlings with fertilizer, avoiding spray dead zones, and improving fertilizer utilization and fertilization effectiveness.
