Description

Technical Field

[0001] This utility model belongs to the field of fertilization device technology, specifically, it relates to a cabbage water and fertilizer integrated fertilization device. Background Technology

[0002] Fertilization refers to agricultural techniques that apply fertilizer to the soil or spray it on plants to provide the nutrients needed by the plants and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich the soil and improve economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain the sustainable development of agriculture.

[0003] Chinese Patent CN218125491U discloses a simple integrated water and fertilizer fertilization device for open-field cabbage. Its structure includes a base support plate, with the upper front right side of the base support plate fixedly connected to the left side of the fertilizer tank connecting rod. By incorporating a fertilizer tank and a water tank, the internal winding discs of these tanks can wind up the winding belt, causing a semi-circular moving plate to slide to the right, making the addition of water and fertilizer convenient and simple. It also allows for precise discharge of water and fertilizer, making the mixed solution more suitable for fertilizing the cabbage field. The device includes a water and fertilizer mixing tank and a spraying device. A liquid pump extracts the water and fertilizer mixture, and the rotation of bevel gears and side bevel gears drives the connecting long pipe to rotate clockwise and counterclockwise, allowing the water and fertilizer mixture to be evenly sprayed onto the cabbage field. It can spray the entire cabbage field. Simply pushing the integrated water and fertilizer fertilization device is sufficient to fertilize the cabbage field, improving fertilization efficiency.

[0004] However, in actual use, the fertilizer bucket needs to be fixed to the base support plate by a connecting rod, which restricts the position of the fertilizer bucket. When workers need to inject fertilizer into the fertilizer bucket, they must first move the bag or bucket containing the fertilizer raw material to the fixed fertilizer bucket. Then, they must manually lift the bag or bucket containing the fertilizer raw material so that the direction of pouring the raw material is aligned with the opening of the fertilizer bucket before the fertilizer can be poured into the bucket. During the entire operation, because the fertilizer bucket cannot be moved flexibly and the fertilizer raw material usually has a certain weight, the lifting and pouring actions require continuous manual labor, resulting in a cumbersome and inefficient fertilizer injection process, and also increasing the workload of the workers.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a cabbage water and fertilizer integrated fertilization device, which solves the problems mentioned in the background technology.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A cabbage fertigation device includes: a mobile cart, a mounting base slidably fitted on the upper side of the mobile cart, multiple fertilizer tanks detachably mounted on the upper side of the mounting base, a water-fertilizer mixing tank mounted on the upper side of the mobile cart, and a spraying device fixed on the upper side of the mobile cart, the spraying device being connected to the water-fertilizer mixing tank.

[0009] The fertilizer tank has multiple casters on its lower side. One side of the fertilizer tank is connected to a pipe, and a ball valve is rotatably fitted inside the pipe. Gears are rotatably fitted on both opposite outer sides of the pipe. The gears are fixedly connected to the ball valve. One side of the water-fertilizer mixing box has multiple slots, which are connected to the pipe. The opposite inner sides of the slots are provided with toothed grooves, which mesh with the gears.

[0010] Optionally, the mobile cart includes a support plate with multiple rollers fixed to the underside of the support plate and a push handle fixed to one side of the support plate. The spraying device and the water-fertilizer mixing box are fixed to the upper side of the support plate, and the mounting base is slidably fitted on the upper side of the support plate.

[0011] Optionally, two channels are provided on the upper side of the support plate, and two sets of guide wheels are installed on the lower side of the mounting base, with the two sets of guide wheels located in the two channels respectively.

[0012] Optionally, an electric push rod is fixed to the upper side of the support plate, and the output end of the electric push rod is fixedly connected to the mounting base.

[0013] Optionally, a rod is fixed on one side of the mounting base, a positioning groove is provided on the upper side of the rod, a slot is provided on one side of the water-fertilizer mixing tank, and a positioning rod is elastically fitted on the upper side of the water-fertilizer mixing tank. One end of the positioning rod extends into the slot and cooperates with the rod and the positioning groove.

[0014] Optionally, a motor is fixed to one side of the water-fertilizer mixing tank, and a stirring rod is rotated inside the water-fertilizer mixing tank. The output end of the motor is fixedly connected to one end of the stirring rod.

[0015] Optionally, the spraying device includes a water pump and a spray pipe. The water pump is connected to the water-fertilizer mixing tank and the spray pipe, and the spray pipe is fixed to the upper side of the support plate.

[0016] Optionally, the spray pipe is an arc-shaped pipe, and multiple nozzles are provided on the outer side of the arc-shaped pipe.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] 1. The mobile cart is based on a support plate, with multiple rollers on its lower side and a push handle on one side, allowing workers to easily push the device to move flexibly in the cabbage planting area without having to carry heavy equipment, thus reducing labor intensity during movement. At the same time, the fertilizer tank adopts a detachable design and is equipped with casters on its lower side. When the fertilizer tank is filled with fertilizer or water, increasing its weight, workers can easily pull the fertilizer tank with the casters, making it convenient to complete the filling operation in a convenient location, further reducing manpower consumption.

[0019] 2. The electric push rod is fixedly connected to the mounting base. The output end can extend and retract to automatically move the mounting base closer to or away from the water-fertilizer mixing tank without the need for manual pushing or pulling of the mounting base. With the groove on the bearing plate and the guide wheel on the lower side of the mounting base, the mounting base can slide smoothly along a fixed trajectory when moving, which not only improves the convenience of operation, but also avoids the deviation problem caused by manual pushing, and reduces the difficulty of operation.

[0020] 3. The upper side of the mounting base has a pre-set groove that matches the moving wheels of the fertilizer tank. When the fertilizer tank is placed, the moving wheels are embedded in the groove, which can quickly complete the positioning of the fertilizer tank and prevent the fertilizer tank from shifting during the movement of the mounting base. At the same time, when the mounting base moves, the plug on one side is inserted into the slot of the water-fertilizer mixing box. The chamfer at the end of the plug and the positioning rod causes the positioning rod to spring up. After the tube body and the slot are fully aligned, the positioning rod is locked into the positioning groove of the plug under the action of the spring, realizing the stable locking of the mounting base and the water-fertilizer mixing box. This prevents the connection from loosening due to vibration during fertilization and ensures stable fertilizer delivery.

[0021] 4. When the pipe of the fertilizer tank is inserted into the groove of the water-fertilizer mixing tank, the gear on the outside of the pipe meshes with the tooth groove on the inside of the groove and rotates, which synchronously drives the ball valve inside the pipe to rotate to release the blockage. This ensures that the pipe and the groove are connected at the same time and achieve automatic conduction without the need for manual operation of the ball valve. This improves the synchronization of connection and conduction and avoids leakage problems caused by human operation errors.

[0022] 5. The bottom of the inner wall of the fertilizer tank is equipped with a first inclined block, which can guide the fertilizer or water in the tank to converge towards the pipe body, ensuring that the material is fully discharged through the pipe body and reducing the amount of residue in the fertilizer tank; the bottom of the water-fertilizer mixing tank is equipped with a second inclined block, which can guide the mixed water and fertilizer in the tank to converge towards the water pump, so that the water pump can fully extract the water and fertilizer, reduce the residue in the water-fertilizer mixing tank, avoid waste of fertilizer and water, and improve resource utilization.

[0023] 6. The motor on one side of the water and fertilizer mixing tank drives the stirring rod inside the tank to rotate, which can fully mix the fertilizer and water entering the tank, ensuring that the water and fertilizer are mixed evenly and avoiding nutrient imbalance in the cabbage plants due to uneven mixing, thus ensuring the quality of cabbage growth; at the same time, the mixing process does not require manual intervention, improving mixing efficiency.

[0024] 7. The water pump of the spraying device can stably draw uniform water and fertilizer from the water-fertilizer mixing tank and pressurize and deliver it to the arc-shaped spray pipe. The arc-shaped spray pipe, together with multiple nozzles on the outside, can widen the spray coverage area, so that the water and fertilizer can be evenly spread to the cabbage plants on both sides, avoiding local over-fertilization or omissions. Compared with the traditional straight spray pipe, the arc-shaped spray pipe has a larger single fertilization area, improving the efficiency of fertilization operations, while ensuring the uniformity of nutrient supply to the cabbage plants, further promoting cabbage growth.

[0025] 8. Solenoid valves are installed in the slots of the water-fertilizer mixing tank and work in conjunction with the controller on the mobile cart. The staff can control the opening and closing of the solenoid valves in each slot individually through the controller, thereby adjusting the amount of fertilizer and water entering the different fertilizer tanks, realizing the control of the water-fertilizer ratio. The ratio can be flexibly adjusted according to the nutrient requirements of different growth stages of cabbage, meeting the personalized fertilization needs during the cabbage growth process, and improving the targeting and scientific nature of fertilization.

[0035] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] Please see Figure 1-5 As shown, this embodiment provides a cabbage fertigation device, including: a mobile cart 1, a mounting base 2 slidably fitted on the upper side of the mobile cart 1, multiple fertilizer tanks 3 detachably mounted on the upper side of the mounting base 2, a water-fertilizer mixing tank 4 mounted on the upper side of the mobile cart 1, and a spraying device 5 fixed on the upper side of the mobile cart 1, which is connected to the water-fertilizer mixing tank 4.

[0038] The fertilizer tank 3 has multiple casters 6 on its lower side. One side of the fertilizer tank 3 is connected to a pipe body 7. A ball valve 8 is rotatably fitted inside the pipe body 7. Gears 9 are rotatably fitted on both opposite outer sides of the pipe body 7. The gears 9 are fixedly connected to the ball valve 8. One side of the water-fertilizer mixing box 4 has multiple slots 10. The slots 10 are connected to the pipe body 7. The opposite inner sides of the slots 10 are provided with toothed grooves 11. The toothed grooves 11 mesh with the gears 9.

[0039] Working principle:

[0040] When in use, staff first use the convenience of the mobile cart 1 to push the device to the cabbage planting area;

[0041] To add water and fertilizer, the staff can remove multiple fertilizer buckets 3 and add water and fertilizer to each fertilizer bucket 3 respectively. After the fertilizer and water are added, the fertilizer bucket 3 is placed on the mounting base 2, and then the mounting base 2 is pushed to move it toward the water and fertilizer mixing tank 4, so that the pipe 7 on one side of the fertilizer bucket 3 is inserted into the slot 10, thereby connecting with the water and fertilizer mixing tank 4.

[0042] During the process of inserting the pipe body 7 into the slot 10, the gear 9 and the tooth groove 11 mesh and rotate with each other. The rotation of the gear 9 will drive the ball valve 8 to rotate, thereby releasing the blockage of the pipe body 7 by the ball valve 8, so that the pipe body 7 can be connected to the water and fertilizer mixing box 4.

[0043] It is worth mentioning that a solenoid valve is installed in the slot 10 of the water-fertilizer mixing tank 4, and a controller is fixed on the upper side of the mobile trolley 1. The controller and the solenoid valve work together. When the fertilizer tank 3 is connected to the water-fertilizer mixing tank 4 through the pipe 7, the solenoid valve will be in the state of blocking the end of the pipe 7. At this time, the staff can control the opening or closing of the solenoid valve through the controller, so that the fertilizer and water in multiple fertilizer tanks 3 can enter the water-fertilizer mixing tank 4 through the opened solenoid valve, thereby completing the fertilizer and water ratio.

[0044] When it is necessary to fertilize the cabbage field, push the mobile cart 1 to move it, and then start the spraying device 5. The spraying device 5 will draw the water and fertilizer that has been mixed in the water and fertilizer mixing tank 4 and spray it to complete the fertilization operation of the cabbage field.

[0045] The fertilizer tank 3 adopts the same basic structure as the water tank in the prior art, and a first inclined block is added to the bottom of its inner wall. The first inclined block can guide the fertilizer or water in the fertilizer tank 3 to converge towards the pipe body 7, so as to ensure that the material in the tank can be discharged more fully through the pipe body 7, reduce the amount of residue, and avoid waste of resources.

[0046] In addition, the casters 6 on the lower side of the fertilizer tank 3 allow workers to easily move the tank when it is full of fertilizer or water, which increases its overall weight, without having to lift it by force. The casters 6 can be used to move the tank easily by pushing or pulling it. At the same time, the detachable design of the fertilizer tank 3 allows workers to remove the empty tank directly and add fertilizer or water to a more convenient location, reducing the labor intensity during the filling process and improving the ease of operation.

[0047] like Figure 1-2 As shown, the mobile cart 1 in this embodiment includes a support plate 12, a plurality of rollers 13 are fixed on the lower side of the support plate 12, a push handle 14 is fixed on one side of the support plate 12, the spraying device 5 and the water-fertilizer mixing box 4 are both fixed on the upper side of the support plate 12, and the mounting base 2 is slidably fitted on the upper side of the support plate 12.

[0048] The mobile cart 1 uses the support plate 12 as the basic support component. Multiple rollers 13 on its lower side allow the entire device to move flexibly in the cabbage planting area. Workers can easily push the device to different fertilization positions using the push handle 14 on one side, providing convenient mobility for fertilization operations.

[0049] like Figure 2-5 As shown, in this embodiment, the upper side of the support plate 12 has two channels 15, and the lower side of the mounting base 2 is equipped with two sets of guide wheels 16, which are located in the two channels 15 respectively. An electric push rod 17 is fixed on the upper side of the support plate 12, and the output end of the electric push rod 17 is fixedly connected to the mounting base 2. An insertion rod 18 is fixed on one side of the mounting base 2, and a positioning groove 19 is opened on the upper side of the insertion rod 18. A slot 20 is opened on one side of the water-fertilizer mixing tank 4, and a positioning rod 21 is elastically fitted on the upper side of the water-fertilizer mixing tank 4. One end of the positioning rod 21 extends into the slot 20 and cooperates with the insertion rod 18 and the positioning groove 19.

[0050] The electric push rod 17 can directly drive the mounting base 2 to move closer to or further away from the water-fertilizer mixing tank 4 through the extension and retraction of its output end, without the need for manual pushing and pulling, thus reducing the intensity of operation.

[0051] The upper side of the mounting base 2 has multiple grooves, the size of which is adapted to the moving wheels 6 on the lower side of the fertilizer tank 3. When the staff places the fertilizer tank 3 on the mounting base 2, the moving wheels 6 can be embedded in the grooves to quickly position the fertilizer tank 3 and prevent it from shifting during the movement of the mounting base 2. At this time, the electric push rod 17 is activated. Under its thrust, the mounting base 2 will move smoothly along a fixed trajectory to the side of the water-fertilizer mixing tank 4 with the sliding cooperation between the lower guide wheel 16 and the groove 15 on the bearing plate 12. At the same time, it will drive the fertilizer tank 3 that has been positioned above to move synchronously, so that the tube 7 on one side of the fertilizer tank 3 is inserted into the groove 10 of the water-fertilizer mixing tank 4 to complete the docking preparation.

[0052] In addition, both the end of the insertion rod 18 and the end of the positioning rod 21 are designed with chamfered structures. As the mounting base 2 approaches the water-fertilizer mixing box 4, the insertion rod 18 on one side of the mounting base 2 will first be inserted into the slot 20 of the water-fertilizer mixing box 4. When inserted, the chamfer of the insertion rod 18 will collide and slide with the chamfer of the positioning rod 21, and the positioning rod 21 will spring up upward through the guide effect of the inclined surface.

[0053] When the mounting base 2 moves to the position where the pipe body 7 and the slot 10 are fully aligned, the positioning rod 21 will be aligned with the positioning groove 19 on the insertion rod 18. At this time, the positioning rod 21 will return to its original position under its own elastic force and be inserted into the positioning groove 19, thereby locking the insertion rod 18. This structure works in conjunction with the electric push rod 17 to ensure the moving accuracy of the mounting base 2 through the electric push rod, and to firmly fix the mounting base 2 to one side of the water-fertilizer mixing tank 4 through the positioning structure, so as to avoid loosening of the connection due to vibration during the subsequent fertilizer transportation process and ensure the stability of the operation.

[0054] In this embodiment, a motor 22 is fixed on one side of the water-fertilizer mixing tank 4, and a stirring rod is rotatably connected inside the water-fertilizer mixing tank 4. The output end of the motor 22 is fixedly connected to one end of the stirring rod.

[0055] The motor 22 is configured to drive the stirring rod to rotate inside the water-fertilizer mixing tank 24, thereby mixing the water and fertilizer inside.

[0056] like Figure 1 As shown, the spraying device 5 in this embodiment includes a water pump 23 and a spraying pipe 24. The water pump 23 is connected to the water-fertilizer mixing tank 4 and the spraying pipe 24. The spraying pipe 24 is fixed on the upper side of the support plate 12. The spraying pipe 24 in this embodiment is an arc-shaped pipe, and multiple nozzles are provided on the outer side of the arc-shaped pipe.

[0057] The water pump 23 is set as the power core for water and fertilizer transportation. It can stably draw the water and fertilizer that has been fully mixed in the water and fertilizer mixing box 4 and pressurize and transport it to the spray pipe 24. After the water and fertilizer enter the spray pipe 24, they will be sprayed evenly through multiple nozzles on the outside of the pipe body and directly act on the cabbage planting area to complete the fertilization operation.

[0058] In addition, the spray pipe 24 is specially designed with an arc structure, which can widen the coverage of the nozzle and allow water and fertilizer to be spread more evenly to the cabbage plants on both sides, avoiding local over-fertilization or omission. This not only improves the efficiency of a single fertilization operation, but also ensures the uniformity of nutrient supply during the growth of cabbage.

[0059] The bottom of the water-fertilizer mixing tank 4 may be provided with a second inclined block; the second inclined block can guide the fertilizer that has been mixed in the water-fertilizer mixing tank 4 to converge towards the pump body, reduce the amount of residue in the water-fertilizer mixing tank 4 and avoid waste of resources.

[0060] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.

[0061] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
