Description

Technical Field

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

[0002] Wheat is a cereal crop widely cultivated around the world, and its grains are a staple food for humans. During its growth, wheat needs to absorb many nutrients to ensure its normal growth, especially during its nutrient-rich period. If the wheat doesn't receive enough nutrients, its growth will be affected, negatively impacting its yield. Therefore, topdressing is necessary according to the nutrient requirements of each growth stage. Growers typically apply fertilizer to the roots of the wheat to effectively promote its growth.

[0003] A search revealed that patent CN 220402384 U discloses a portable, lightweight, precision drip irrigation and fertilization machine for wheat and corn. The machine includes a platform with a water storage tank and a mixing mechanism fixedly connected to it. Four pulleys are fixedly connected below the platform. The water storage tank and mixing mechanism are connected via a water inlet mechanism. The mixing mechanism includes an outer cylinder and an inner cylinder, which are slidably connected. The outer cylinder is fixedly connected to a drip irrigation device, which penetrates the outer cylinder and extends to its outer side. The drip irrigation device includes a water pump, two water inlet pipes, and a limiting platform. The water pump is located inside the outer cylinder, and the water inlet pipes are fixedly connected to it, penetrating the outer cylinder and extending to its outer side. The limiting platform is fixedly connected to the outer wall of the outer cylinder, and the two water inlet pipes are fixedly connected to the upper and lower inner walls of the limiting platform, respectively.

[0004] However, the above-mentioned device still has the following problems: when drip irrigating wheat, although nutrients are dripped out with the water flow, they are mainly concentrated on the surface and cannot reach the middle or deep part of the root system. This makes it easy for the wheat roots to concentrate in the shallow soil layer area, resulting in unstable rooting. Utility Model Content

[0005] To address the problem of wheat fertilization being concentrated on the surface in the existing technology, a precision wheat fertilization device is provided to solve the problem of deep fertilization in wheat fertilization.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] This utility model proposes a precision fertilization device for wheat, including a vehicle body with a fertilizer box mounted on it. The vehicle body also includes a lifting assembly comprising a support plate and a lifting plate. The lifting plate has at least one cylinder seat, and a fertilizer cylinder is slidably connected to the cylinder seat. The fertilizer cylinder has several first through holes on its wall. The lower end of the fertilizer cylinder extends beyond the cylinder seat. The number of first through holes protruding from the cylinder seat can be adjusted by a fixing assembly. The upper part of the fertilizer cylinder is connected to the fertilizer box via a pipe, and a valve is mounted on the pipe.

[0008] Preferably, the fertilizer cylinder is slidably connected to an inner cylinder, the top of the inner cylinder has a through hole that can communicate with the pipe, the bottom of the inner cylinder is connected to the fertilizer cylinder through a third elastic element, and the inner cylinder wall has a second through hole that can cooperate with the first through hole.

[0009] Preferably, the fixing component includes a fixing rod, which is fixedly connected to the lifting plate. The fixing rod is fitted with a slider, and the fixing rod has a plurality of locking holes. The slider is connected to a locking rod through a second elastic element, and the locking rod can slide into any one of the locking holes.

[0010] Preferably, the cylinder wall of the cylinder seat has longitudinally distributed elongated holes, the slider is fixedly connected to the fertilizer cylinder, and the slider is slidably disposed in the elongated holes.

[0011] Preferably, the lifting assembly further includes a motor, which is fixed on the support plate. The motor is equipped with a gear, and the lifting plate is fixed with a rack that meshes with the gear.

[0012] Preferably, the support plate is sleeved on the slide rod, one end of the slide rod is fixed to the vehicle body, and the slide rod is sleeved with a first elastic element for resetting the support plate.

[0013] Preferably, the lifting plate is fixedly connected to the guide rod, and the guide rod is slidably connected to the support plate.

[0014] Preferably, the valve connected to the pipeline is a pump body, which is fixed to the vehicle body, and the inlet end of the pump body extends into the fertilizer tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By cooperating with the clamp rod, the fertilizer cylinder slides on the fixed rod to adjust the length of the fertilizer cylinder extending out of the cylinder base, thereby adjusting the depth of fertilization when fertilizing the wheat roots and achieving precise fertilization.

[0017] 2. By using a support plate, a sliding rod, and a first spring, the device can move forward continuously when the fertilizer cylinder is inserted into the soil for fertilization, thereby improving fertilization efficiency.

[0018] 3. By using a third spring to alternately set the inner cylinder and the fertilizer cylinder, the first and second passages can only form a channel when the inner cylinder is under the pressure generated by the pump body, which is conducive to fertilization. When the pressure is released, the inner cylinder moves upward to separate the first and second passages, which can effectively prevent soil from entering the inner cylinder and also prevent the first and second passages from being blocked by soil, thereby improving fertilization efficiency.

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1:

[0028] like Figure 1 - Figure 4As shown in the figure, this embodiment proposes a precision fertilization device for wheat, including a vehicle body 1, on which a fertilizer box and a controller are installed. The fertilizer box contains fertilizers in different proportions according to different stages of wheat growth, so that the fertilization can adapt to the nutrients required for wheat growth.

[0029] Furthermore, to better implement fertilization, the fertilizer used is a water-soluble liquid fertilizer.

[0030] Furthermore, the controller is a mature product on the market. It is an integrated circuit and uses a microcontroller or smart chip to achieve automatic control based on corresponding signals. It can also make precise adjustments and controls to the actuators of the controlled actions in terms of distance or time, so as to achieve precise control of different action requirements of the device and precise control of fertilizer requirements for different growth stages of wheat.

[0031] Specifically, the controller is a programmable logic controller (PLC). A programmable logic controller is a digital computing and operating electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations. It controls various types of mechanical equipment or production processes through digital or analog inputs and outputs.

[0032] A pump body 2 is fixed on the fertilizer tank. The inlet end of the pump body 2 extends into the fertilizer tank, and the outlet of the pump body 2 is connected to the pipe 15. The pump body 2 is electrically connected to the controller, which can achieve precise control of the working time under the control of the controller, thereby achieving precise control of the start and stop of the pump body 2, and achieving the purpose of precise control of fertilizer application.

[0033] Furthermore, the pump body 2 uses a water pump as its working component, which is a mature product on the market and can be selected according to usage requirements.

[0034] A sliding rod 3 is fixedly connected to one end of the vehicle body 1 in the forward direction. The sliding rods 3 are symmetrically arranged. A support plate 5 is sleeved on the sliding rod 3. The sliding rod 3 is fitted with a first elastic element for resetting the support plate 5. The first elastic element is a first spring 4. The support plate 5 and the sliding rod 3 can slide relative to each other. The left end of the first spring 4 is connected to the support plate 5, and the right end of the first spring 4 is connected to the vehicle body 1. When the support plate 5 is stationary due to the resistance of the fertilizer cylinder 11 after it is inserted into the soil, the vehicle body 1 moves slowly by compressing the first spring 4. When the fertilizer cylinder 11 leaves the soil, the resistance of the support plate 5 disappears, and the first spring 4 resets, causing the support plate 5 to slide back to its original position on the sliding rod 3, thereby enabling the device to move forward continuously and improving fertilization efficiency.

[0035] Furthermore, a buffer pad is fixedly installed at the end of the slide bar 3 away from the vehicle body 1, which can effectively prevent the support plate 5 from causing large vibrations to the device when it resets under the action of the first spring 4.

[0036] A motor 7 is fixed to a support plate 5. The motor 7 is equipped with a gear 19, which meshes with a rack 17. A lifting plate 9 is fixedly connected to the lower end of the rack 17. A guide rod 6 is slidably connected to the support plate 5. The guide rod 6 passes through the support plate 5 and is fixedly connected to the lifting plate 9 at its lower end. The motor 7 is electrically connected to a controller. Under the control of the controller, the motor 7 can rotate in both directions. Through the cooperation of the guide rod 6 and the rack 17, the lifting plate 9 can be raised and lowered under the action of the motor 7 and the rack 17. The moving distance of the lifting plate 9 is adjusted according to the root depth of wheat at different growth stages.

[0037] Furthermore, the motor 7 is a mature product on the market. The motor 7 is a motor with a brake, which can ensure that the gear 19 is in a stopped state when the machine stops, so as to prevent the rack 17 from falling due to the gravity of the object below and avoid potential damage to the device.

[0038] Furthermore, to better achieve precision fertilization, in the first method, since the parameters of gear 19 are fixed, the controller can control the distance of rack 17 by adjusting the working time of motor 7, thereby controlling the moving distance of lifting plate 9. When the required moving distance is reached, the controller controls motor 7 to stop rotating, and then the controller controls pump 2 to work.

[0039] Furthermore, to better achieve precision fertilization, the second method can also be implemented by equipping the rack 17 with an infrared ranging sensor, placing a reflector on the support plate 5 that works in conjunction with the infrared ranging sensor, and electrically connecting the infrared ranging sensor to the controller. By detecting the distance with the infrared ranging sensor, the movement distance of the lifting plate 9 can be controlled when the rack 17 reaches the set moving distance, causing the motor 7 to stop, while the controller controls the operation of the pump body 2.

[0040] Specifically, infrared rangefinders are a mature product on the market. An infrared rangefinder has a pair of infrared signal emitting and receiving diodes. It emits a beam of infrared light, which reflects off an object, reaching the sensor where the signal is received. The time difference between transmission and reception is then processed by a CCD image processor to calculate the distance to the object. Infrared rangefinders can be used on natural surfaces or with reflectors, offering long measurement distances and high frequency response, making them suitable for various working environments.

[0041] The lifting plate 9 is fixedly connected to a fixed rod 12, and a slider 16 is sleeved on the fixed rod 12. The fixed rod 12 is provided with several locking holes 13. The slider 16 is connected to a locking rod 14 through a second elastic element, which is a second spring 8. One end of the second spring 8 is connected to the slider 16, and the other end of the second spring 8 is connected to the locking rod 14, so that the locking rod 14 can slide into any of the locking holes 13, and after the slider 16 slides and adjusts its position on the fixed rod 12, it is fixed by the locking rod 14.

[0042] The lifting plate 9 is provided with at least one cylinder seat 10, and the cylinder seat 10 is slidably connected to a fertilizer cylinder 11. The upper part of the fertilizer cylinder 11 is connected to a pipe 15. Several first through holes 20 are provided on the cylinder wall of the fertilizer cylinder 11. The lower end of the fertilizer cylinder 11 extends out of the cylinder seat 10. The fertilizer cylinder 11 is located in the internal cavity of the cylinder seat 10. The cylinder wall of the cylinder seat 10 is provided with longitudinally distributed elongated holes. The slider 16 is fixedly connected to the fertilizer cylinder 11 and is slidably disposed in the elongated holes. With the cooperation of the locking rod 14 and the locking hole 13, the position of the slider 16 on the fixed rod 12 is adjusted, thereby realizing the fixing of the fertilizer cylinder 11 after adjusting the distance H of the moving part of the cylinder seat 10. The number of first through holes 20 on the fertilizer cylinder 11 exposed on the cylinder seat 10 is adjusted. The distance of the fertilizer cylinder 11 inserted into the soil is controlled by the moving distance of the lifting plate 9, thereby achieving precise fertilization by applying fertilizer to the root depth of wheat at different growth stages through the first through holes 20 when the fertilizer cylinder 11 is inserted into the soil.

[0043] Furthermore, to better achieve precise fertilization, the lower end of the fertilizer cylinder 11 is a cone, and the cone and the fertilizer cylinder 11 form a whole, so that the inside of the fertilizer cylinder 11 forms a cavity.

[0044] Furthermore, to better facilitate fertilization, the opening direction of the first through hole 20 is distributed at 180 degrees with the slider 16, which can make the first through hole 20, which is not moved out of the area of ​​the cylinder seat 10 of the fertilizer cylinder 11, form a closed state, thereby ensuring that when the wheat roots are fertilized, the fertilizer flows out from the first through hole 20 inserted into the soil by the fertilizer cylinder 11.

[0045] Furthermore, to better achieve precise fertilization, pipe 15 is made of flexible hose to accommodate the movement of fertilizer cylinder 11. When connecting pipe 15 and fertilizer cylinder 11, the connection is achieved through commonly used pipe connection methods such as four-way, three-way or two-way connections.

[0046] Furthermore, to facilitate the movement of the device, rollers are installed under the vehicle body 1.

[0047] Furthermore, to better propel the device forward, a walking motor can be installed on one of the sets of rollers under the vehicle body 1 to provide walking power. This is a mature product on the market, and the walking motor is electrically connected to the controller.

[0048] Furthermore, this device is also equipped with a storage battery as a power source. The storage battery is a mature product on the market and is not shown.

[0049] Example 2:

[0050] like Figure 1 - Figure 4 As shown, the other structures are the same as in Embodiment 1. The difference is that, in this embodiment, considering that when the fertilizer cylinder 11 is inserted into the soil, the first through hole 20 is easily blocked by the soil, and the soil can easily enter the interior of the fertilizer cylinder 11 through the first through hole 20 and deposit, which reduces the internal volume of the fertilizer cylinder 11 and thus affects the amount of fertilizer applied during precise fertilization, further improvements are made to the interior of the fertilizer cylinder 11 based on Embodiment 1.

[0051] The inner cylinder 23 is slidably connected to the inside of the fertilizer cylinder 11. The top of the inner cylinder 23 has a through hole that can communicate with the pipe 15. The bottom of the inner cylinder 23 is solid, forming an internal cavity structure. The bottom of the inner cylinder 23 is connected to the fertilizer cylinder 11 through a third elastic element, which is a third spring 22. The upper end of the third spring 22 is connected to the bottom of the inner cylinder 23, and the lower end of the third spring 22 is connected to the bottom of the cavity of the fertilizer cylinder 11. The inner cylinder 23 has a second through hole 21 that can cooperate with the first through hole 20. The elastic force of the third spring 22 is less than the pressure generated by the pump body 2 when fertilizing.

[0052] When the pump body 2 is working and applying fertilizer, the pressure in the inner cylinder 23 increases as fertilizer enters, thereby compressing the third spring 22. This causes the first through hole 20 and the second through hole 21 to form a channel under the pressure generated by the pump body 2, which is beneficial for fertilization. When the pump body 2 stops working and the pressure disappears, the inner cylinder 23 moves upward under the elastic force of the third spring 22, causing the first through hole 20 and the second through hole 21 to separate. This effectively prevents soil from entering the inner cylinder 23 when the fertilizer cylinder 11 is pulled out of the soil, and also prevents the first through hole 20 and the second through hole 21 from becoming blocked, thereby improving fertilization efficiency.

[0053] When the fertilizer tube 11 is inserted into the soil, the first through hole 20 and the second through hole 21 are kept separate to ensure that the soil does not block the first through hole 20 and the second through hole 21 when the fertilizer tube 11 is inserted into the soil. It also prevents the soil from entering the interior of the fertilizer tube 11 through the first through hole 20 and depositing, which would reduce the internal volume of the fertilizer tube 11 and affect the amount of fertilizer applied during precise fertilization.

[0054] Working principle and usage process of this utility model:

[0055] S1: Move vehicle 1 to the wheat field to be fertilized, dissolve the appropriate fertilizer in water according to the wheat growth stage, and then add it to the fertilizer tank of vehicle 1.

[0056] S2: By pulling the lever 14, adjust the distance H of the fertilizer cylinder 11 extending out of the cylinder seat 10 for precise fertilization. After adjustment, make the lever 14 re-engage into the locking hole 13.

[0057] Adjust the controller's parameter settings for the movement distance of rack 17 according to the wheat's growth status.

[0058] S3: The motor 7 is started by the controller, the rack 17 is moved downward by the gear 19, and then the fertilizer cylinder 11 is inserted into the soil by the lifting plate 9.

[0059] S4: When the controller controls the rack 17 to reach the set moving distance, the controller stops the motor 7 from rotating and starts the pump body 2 at the same time, so that the fertilizer in the fertilizer tank enters the fertilizer cylinder 11 through the pipe 15, and then enters the inner cylinder 23 through the through hole at the upper end of the inner cylinder 23.

[0060] When the fertilizer cylinder 11 is inserted into the soil, the first through hole 20 and the second through hole 21 are misaligned. As the pump body 2 continuously pumps fertilizer into the inner cylinder 23, the pressure increases, which compresses the third spring 22, connecting the first through hole 20 and the second through hole 21, allowing the fertilizer to flow out and reach the wheat root area.

[0061] S5: The controller controls the pump body 2 to run for a sufficient time to ensure that the amount of fertilizer applied to the wheat is appropriate, and then the controller controls the water pump 2 to stop.

[0062] When the pressure in the inner cylinder 23 disappears, it resets under the action of the third spring 22, causing the first through hole 20 and the second through hole 21 to be staggered again, thus preventing soil from entering the fertilizer cylinder 11.

[0063] At the same time, the controller controls the motor 7 to rotate in the opposite direction, causing the rack 17 to move upward and pull the fertilizer cylinder 11 out of the soil.

[0064] S6: While performing steps S3-S5, the vehicle body 1 continues to move forward at a constant speed, the fertilizer cylinder 11 is inserted into the soil, so that the support plate 5 is constrained by the guide rod 6 and the rack 7 and remains stationary, and the vehicle body 1 moves forward to compress the first spring 4.

[0065] When the fertilizer cylinder 11 is pulled out of the soil, the constraint force of the first spring 4 disappears, causing the support plate 5 to drive the lifting plate 9 to reset, which is exactly in the next wheat area that needs to be fertilized.

[0066] S7: Repeat steps S3-S6 to complete the overall fertilization of wheat.

[0067] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
