Description

Technical Field

[0001] This utility model relates to the field of soil improvement and fertilization technology, and in particular to a fertilization device for soil improvement. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to produce products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. Agricultural planting improves planting efficiency by fertilizing and improving the soil, and fertilization is necessary during soil improvement.

[0003] A search revealed that patent CN213548247U discloses a fertilization device for soil improvement; however, this fertilization device has the following shortcomings in use:

[0004] During use, the soil is sprayed through the nozzles of the split pipe. However, the spraying range of the nozzles is limited. When it is necessary to spray both sides of the vehicle frame, the entire vehicle needs to be moved back and forth for spraying, which is inefficient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, which involve spraying soil through nozzles in a split pipe. However, the nozzles have a limited spraying range, and when spraying both sides of the vehicle frame is required, the entire unit needs to be moved back and forth, resulting in low efficiency. Therefore, this invention proposes a fertilization device for soil improvement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fertilization device for soil improvement includes a base, a liquid tank for holding liquid fertilizer fixedly mounted on the top of the base, a fertilizer tank for holding solid fertilizer fixedly mounted on one side of the top of the base, the top of the fertilizer tank being concave and the bottom being U-shaped, universal wheels for easy movement being fixedly mounted at the four corners of the bottom of the base, a connecting frame for connecting to external machinery being fixedly mounted on one side of the top of the base, the connecting frame having connecting holes, and a fertilization mechanism mounted on the top of the liquid tank, which can apply fertilizer to the front and sides of the base when fertilization is required.

[0008] To facilitate the removal of solid fertilizer from the fertilizer bin, the fertilizer bin also includes a push-out mechanism. When it is inconvenient for personnel to remove the solid fertilizer from the fertilizer bin, the push-out mechanism can lift the fertilizer from the fertilizer bin.

[0009] In one possible design, the fertilization mechanism includes a water pump, a housing, two expansion tanks, and a front housing. The bottom of the water pump is fixedly connected to the top of the liquid tank. A support plate is fixedly installed on the top of the liquid tank. The bottom of the housing is fixedly connected to the top of the support plate. An extraction pipe is fixedly installed at the inlet of the water pump, with one end of the extraction pipe penetrating the top of the liquid tank and extending into the liquid tank. A delivery pipe is fixedly installed at the outlet of the water pump, with one end of the delivery pipe fixedly connected to and communicating with the top of the housing. Three fixed pipes are fixedly installed on one side of the housing and are interconnected. A first valve is installed on each of the fixed pipes. One end of each of the two fixed pipes is fixedly installed with a telescopic hose, and one end of each of the two telescopic hoses is fixedly connected to and communicating with the top of the expansion tank. A second connecting pipe is fixedly installed on the top of the front housing, with one end of the second connecting pipe fixedly connected to one of the fixed pipes. Multiple nozzles are fixedly installed at the bottom of both the expansion tank and the bottom of the front housing and are interconnected.

[0010] In one possible design, the ejection mechanism includes an electric push rod and a top plate. One end of the electric push rod is fixedly connected to the inner top wall of the fertilizer box, and the telescopic part extends through the bottom of the fertilizer box. The outer side of the top plate is slidably connected to the inner wall of the fertilizer box. The size of the top plate is adapted to the inner wall of the fertilizer box. The bottom of the top plate is fixedly connected to the telescopic part of the electric push rod.

[0011] In one possible design, a U-shaped frame for storing the two expansion boxes when not in use is fixedly installed on one side of the liquid tank. T-shaped grooves are opened on the inner walls of both sides of the U-shaped frame. T-shaped sliders that cooperate with the grooves are slidably connected to the inner walls of the grooves. One end of the T-shaped slider is fixedly connected to one side of the expansion box, and the front box is fixedly connected to one side of the U-shaped frame.

[0012] In one possible design, two insertion holes are provided at both ends of the top of the U-shaped frame, and an L-shaped plate is fixedly installed on one side of the top of the expansion box. A nut is embedded in the top of the L-shaped plate, and a bolt for fixing the position of the expansion box is connected to the internal thread of the nut. The bottom end of the bolt is inserted into the insertion hole.

[0013] In one possible design, the bolt has multiple through holes, one of which contains a wire to prevent the bolt from coming out of the socket.

[0014] In one possible design, the top of the liquid tank is fixedly equipped with a liquid addition pipe for easy addition of liquid fertilizer and is connected to it. A cap is threaded onto the liquid addition pipe. The bottom side of the liquid tank is fixedly equipped with a discharge pipe for easy discharge and replacement and is connected to it. A second valve is installed on the discharge pipe.

[0015] In this application, the external machinery (such as agricultural machinery, tractors) and the connecting frame are connected via connecting holes (e.g., using connecting parts (bolts, nuts) on the agricultural machinery). The cover on the top of the liquid tank's filling pipe is opened, and liquid fertilizer is slowly poured into the liquid tank through the filling pipe. After adding to the appropriate liquid level, the cover is tightened to prevent leakage. If fertilization is needed on both sides and the front of the base simultaneously, the operator rotates the bolt to remove it from the currently inserted socket. The operator then pulls the expansion box (one expansion box is pulled to the left, and the other to the right). The expansion box moves via a sliding groove and a slider. When the expansion box is pulled to one side and cannot be moved further, the bolt is aligned with the other socket. The bolt is rotated to insert it into the corresponding socket for fixation. To prevent the bolt from accidentally coming out of the socket, a wire can be taken, one end inserted into the bolt's through-hole, and the two ends twisted together. Then, the operator... Open the valves on the three fixed pipes, and the external machinery will pull the entire unit to move it. Start the water pump, and the pump will draw liquid fertilizer from the liquid tank through the extraction pipe connected to the inlet, and then transport the liquid fertilizer into the tank through the delivery pipe connected to the outlet. After the liquid fertilizer enters the tank, it will be distributed through the three fixed pipes on one side of the tank. Two of the fixed pipes will transport the liquid fertilizer to the expansion tank through telescopic hoses, and the other fixed pipe will transport the liquid fertilizer to the front tank through the second connecting pipe. The liquid fertilizer will be sprayed out through multiple nozzles at the bottom of the expansion tank and the bottom of the front tank, fertilizing the soil on the front and sides of the base (the nozzles at the bottom of the front tank are set at an angle to prevent spraying onto the liquid tank, and the U-shaped frame has a certain width), achieving large-area fertilization. When fertilization on both sides is not needed, simply close the corresponding first valve. Then push the expansion tank into the U-shaped frame for storage.

[0016] When manual application of solid fertilizer is required, pour the fertilizer into the fertilizer tank to an appropriate level (the fertilizer is located at the top of the top plate). Use your hands to grab the fertilizer and spread it. If it is inconvenient for personnel to remove the solid fertilizer from the tank, activate the electric actuator. The telescopic part of the actuator will extend upwards, causing the top plate to move upwards within the fertilizer tank. The top plate will then lift the solid fertilizer to a suitable height for easy removal. Note that the water pump and electric actuator require an external controller and power supply. A battery installed on the base can provide power. The type of the first and second valves can be selected according to actual needs.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this utility model, a fertilization device for soil improvement is provided with an extension box and a front box through the fertilization mechanism. By pulling the extension box out of the U-shaped frame and fixing it, fertilization can be carried out on the front and sides of the base at the same time without moving the device back and forth, which greatly improves fertilization efficiency and saves time and labor costs. The operator can flexibly choose whether to unfold the extension box according to the actual fertilization needs. When only the front side needs to be fertilized, the corresponding first valve can be closed. When the sides and the front side need to be fertilized at the same time, the extension box can be unfolded and all the first valves can be opened to realize flexible switching of different fertilization areas and meet diverse fertilization scenarios.

[0019] In this utility model, the fertilization device for soil improvement, through the ejection mechanism, when it is inconvenient for personnel to take out solid fertilizer from the fertilizer box, activates the electric push rod, whose telescopic part drives the top plate to move upward in the fertilizer box, lifting the solid fertilizer in the fertilizer box to a suitable height for personnel to grab, avoiding the problem of inconvenience in taking out the fertilizer due to the fertilizer box being too deep or the fertilizer being piled up, and improving the convenience of operation;

[0020] In this invention, the fertilization mechanism can simultaneously fertilize the front and sides of the base without the need for a back-and-forth moving device, greatly improving fertilization efficiency and saving time and labor costs. The ejection mechanism can lift the solid fertilizer in the fertilizer box to a suitable height for easy grabbing by personnel. Attached Figure Description
