Description

Technical Field

[0001] The utility model relates to the technical field of crop planting, in particular to an intelligent plant ash sprayer suitable for the entire growth cycle of spinach. Background Art

[0002] Wood ash is an inorganic farm fertilizer with a wide variety of sources, low cost, complete nutrients, and significant fertilizer efficiency. Spreading wood ash plays a vital role in spinach cultivation. Spinach is not acid-tolerant and prefers to grow in alkaline soil (optimally a pH of 7.3 to 8.2). Spreading a layer of wood ash after sowing spinach can effectively increase the alkalinity of the soil, making such soil more conducive to the healthy growth of spinach. Furthermore, wood ash can loosen the soil and increase soil temperature, which helps spinach seeds emerge faster. Furthermore, wood ash contains a comprehensive range of nutrients, so spinach grown with wood ash will grow tender and green, with an improved taste.

[0003] Currently, most farmers spread wood ash manually, which requires constant bending over and is labor-intensive. Because wood ash is in a powdery state, manual spreading easily creates dust. Furthermore, the thickness of the spread cannot be precisely controlled, making it difficult to achieve a uniform application rate. This leads to uneven plant growth and nutritional imbalances. If wood ash is not thoroughly broken up before use, it can also cause localized soil pH to be excessively high, impacting soil quality and crop health.

[0004] A search revealed a Chinese patent (CN105794377A) that discloses a plant ash spreading device. This device aims to provide a mobile, human-like ash spreading system that is easy to move, effectively suppresses dust fly-by during ash spreading, ensures a uniform ash thickness, and reduces the time and effort required for manual operation. However, this solution also suffers from the following issues: It is not highly intelligent, still requires considerable labor, and cannot be applied to specific leaf areas.

[0005] A search revealed a Chinese patent (CN219124769U) that discloses a plant ash spreading device that uses a suction fan as power to automatically spread the ash, reducing workload and improving both speed and uniformity. The suction fan can be swung manually or automatically, expanding the spreading range and reducing the number of times the machine needs to be driven underground. The device can also filter and recover unburned charcoal from the ash. However, its design is limited, as it doesn't account for potential ash clumping, which can lead to ash blockage. The device cannot be used in strong winds. Utility Model Content

[0006] In response to the deficiencies in the above-mentioned background technology, the present invention proposes an intelligent wood ash sprayer suitable for the entire growth cycle of spinach, which solves the problems in the existing technology of high labor intensity, difficult to spread evenly and easy to cause damage to crops and soil in the application of wood ash.

[0007] The technical solution of the utility model is: an intelligent wood ash sprayer suitable for the entire growth cycle of spinach, comprising: a crushing device, an ash spraying device, a spraying device and an air blasting device which are sequentially installed on the upper layer of a vehicle body, the ash outlet of the ash spraying device and the atomizing nozzle of the spraying device are respectively located at two ends of the vehicle frame, the air blasting device and the ash outlet of the ash spraying device are installed on the same side, the crushing device is installed inside an ash storage container, the lower ash outlet of the ash storage container corresponds to the ash delivery pipe of the ash spraying device, and a water storage container is installed on the side of the vehicle body; and an intelligent control center is installed on the lower layer of the vehicle body.

[0008] Furthermore, the crushing device is mainly composed of a high-carbon steel blade and a rotating shaft, and is installed inside the ash storage container. The high-carbon steel blade is symmetrically welded to the surface of the rotating shaft.

[0009] Furthermore, the ash spraying device includes an ash storage container, a micro blower and an ash delivery pipe. The bottom of the ash storage container is connected to the ash delivery pipe, and the micro blower is installed on one side of the ash delivery pipe.

[0010] Furthermore, the spray device includes a water storage container, a plastic water pipe, a water pump and an atomizing nozzle. The water inlet pipe of the water pump is connected to the water storage container, and the water outlet pipe is connected to the atomizing nozzle.

[0011] Furthermore, the air blowing device includes a small fan, an air pump, and a spring cylinder. The spring cylinder is composed of a cylinder barrel, a piston, a spring, and a valve. When the piston moves outward, it pushes the small fan to rotate 90 degrees around the rotating axis toward the outside of the vehicle body. When the piston moves inward, it pulls the small fan back to its original position.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) The utility model is provided with a crushing device, a dust-spraying device, a spraying device and an air-blowing device on the vehicle body, so as to integrate devices with different functions into one body, and at the same time realize the unmanned and automated operation of the mechanical device, effectively ensuring the integration of field operations, and also greatly reducing the input of human resources and the increase in costs caused by frequent replacement of agricultural machinery.

[0014] (2) The utility model adopts a modular design principle, making the utility model easier to maintain. Since each device has a clear function and usage scenario, when modification or maintenance is required, only the specific device needs to be focused on without affecting the entire system. On the other hand, the modular design makes the machine more flexible and the system can be expanded or modified more easily. New functions can be implemented by adding new device modules without having to make large-scale changes to the existing system.

[0015] (3) The utility model can achieve a targeted spraying effect from before the spinach is sown to the peak period of the crop. That is, for different usage scenarios, different device combinations are used to achieve the expected effect. The ash spraying device cooperates with the air blowing device to blow away the ash that falls on the leaves of the seedlings, avoiding the ash from sticking to the leaves and causing burns; the ash spraying device cooperates with the spraying device to wet the leaves first and then spray the ash, ensuring that the ash sticks to the leaves to better prevent insects and provide nutrients; the crushing device can avoid ash discharge blockage caused by wet ash agglomeration, ensuring the smooth operation of the ash spraying device.

[0016] (4) The ash spraying device rationally utilizes the Bernoulli principle, which states that in an incompressible fluid, when the velocity of the fluid increases, its pressure decreases, and vice versa. Unlike traditional ash spraying machines that have many parts and are large in size, this device only uses a micro-blower and an ash delivery pipe to simply and effectively spray the wood ash powder evenly. When the micro-blower is started, the airflow generated will reduce the pressure in the pipe, thereby generating suction on the powdered wood ash in the ash storage container under the action of atmospheric pressure. By adjusting the wind speed of the micro-blower, the amount of wood ash powder sprayed can be controlled.

[0017] (5) The spray device uses an atomizing nozzle. The pressure can be adjusted by rotating the nozzle or the nozzle type can be changed to make the spray form a wide-angle diffusion, thereby achieving coverage of the spraying range. At the same time, parameters such as spray distance and droplet size can also be adjusted according to actual conditions.

[0018] (6) The blowing device consists of a small fan, an air pump and a spring cylinder. The combination of the spring cylinder and the small fan enables it to be retracted and folded, which reduces the size of the device to a certain extent and reflects the advantages of small agricultural machinery.

Therefore, they should not be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or connected in an integral manner; they can be mechanically connected or electrically connected; they can be directly connected, indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The following describes the embodiments of the present invention based on its overall structure.

[0031] like Figure 1-2 As shown, in an embodiment of the present invention, an intelligent wood ash sprayer suitable for the entire growth cycle of spinach includes: a vehicle body 9, the upper layer of the vehicle body 9 is equipped with a crushing device 6, an ash spraying device, a spraying device and a blowing device, the ash spraying device includes an ash storage container 5, a micro blower 2 and an ash delivery pipe 3, the ash delivery pipe 3 is installed in the sleeve 4, the spraying device includes a water storage container 7, a plastic water pipe 13, a water pump 14 and an atomizing nozzle 1, the blowing device includes a small fan 8, an air pump 11 and a spring cylinder 12, and the small fan 8 and the vehicle body 9 are connected by a rotating shaft 15. The ash outlet of the ash delivery pipe 3 of the ash spraying device and the atomizing nozzle 1 of the spraying device are located at opposite ends of the vehicle body 9. The air blowing device and the ash delivery pipe 3 of the ash spraying device are installed on the same side. The crushing device 6 is installed inside the ash storage container. The lower ash outlet of the ash storage container 5 corresponds to the ash delivery pipe 3 of the ash spraying device. The water storage container 7 is installed on the side of the vehicle body and is connected to the water intake of the water pump 14 via a plastic water pipe 13. The water outlet of the water pump 14 is also connected to the atomizing nozzle 1 via a plastic water pipe 13. The intelligent control center 10 is installed in the lower layer of the vehicle body. The intelligent control center 10 is connected to a camera sensor device and enables remote operation through image feedback from the camera sensor device. The intelligent control center 10 also has a Beidou GPS dual-mode navigation module and is connected to the 5G network. This allows low-error remote positioning and low-latency control of agricultural machinery without leaving home, thereby improving the efficiency of various tasks.

[0032] Specifically, the vehicle body 9 adopts a wheel-type running mechanism, which has low resistance, stable driving, convenient turning and lower maintenance and replacement costs, and is suitable for use in plain areas.

[0033] In this embodiment, the recommended operating environment is a spinach planting environment with a row spacing of 20-30 cm and a plant spacing of 10-15 cm. This ensures sufficient space between spinach plants for growth, while also facilitating management and harvesting. When the machine is operating, the two wheels span a row of spinach, with a wheel spacing of approximately 20 cm, ensuring that the crops are not crushed or damaged during movement.

[0034] In this embodiment, spinach seedlings are generally short, with a height of about 5-10 cm. The air blowing device is about 15 cm above the ground, which can provide sufficient wind power to blow off the wood ash powder on the leaves of the seedlings without damaging the seedlings.

[0035] In this embodiment, when spinach reaches maturity, the plant height increases, generally reaching 20-30 cm. At this time, the air blowing device can be folded back into the device via an elastic cylinder to prevent the fan blades from damaging the plant. The spray device is equipped with an atomizing nozzle 1, which can spray water mist over a large area, ensuring that the leaf surface is wetted and the wood ash powder adheres to the leaf surface.

[0036] In this embodiment, if Figure 3-4 As shown, the ash spraying device includes an ash storage container 5, a micro-blower 2 and an ash delivery pipe 3. The bottom of the ash storage container 5 is connected to the ash delivery pipe 3, and the micro-blower 2 is installed on one side of the ash delivery pipe. The ash spraying device rationally applies the Bernoulli principle, that is, in an incompressible fluid, when the velocity of the fluid increases, its pressure will decrease, and vice versa. Different from traditional ash sprayers with many parts and large size, this device only uses a micro-blower and an ash delivery pipe to simply and effectively spray out the wood ash powder evenly. When the micro-blower is started, the airflow generated will reduce the pressure in the pipeline, thereby generating suction on the powdered wood ash in the ash storage container under the action of atmospheric pressure. By adjusting the wind speed of the micro-blower, the amount of wood ash powder sprayed can be controlled.

[0037] In this embodiment, if Figure 5-6 As shown, the blowing device includes a small fan 8, an air pump 11 and a spring cylinder 12. The air pump 11 is used to compress and transport gas; the spring cylinder 12 is composed of a cylinder barrel, a piston, a spring and a valve. A device that uses the elastic force of the spring and the pressure of the gas to achieve motion control. When the compressed air in the cylinder enters the cylinder barrel through the valve, the pressure in the cylinder increases, causing the piston to move outward. At the same time, the spring is compressed and stores elastic potential energy. When the air supply is stopped or the air pressure drops, the spring releases the elastic potential energy and pushes the piston inward. The elastic cylinder is controlled by the air pump. When the piston moves outward, it pushes the small fan 8 to rotate 90° around the rotating shaft toward the outside of the vehicle body. When the piston moves inward, it pulls the small fan 8 back to its original position. The combination of the spring cylinder and the small fan enables it to be retracted and folded, reducing the size of the device to a certain extent, reflecting the advantages of small agricultural machinery.

[0038] In this embodiment, if Figure 7 As shown, the spray device includes a water storage container 7, a plastic water pipe 13, a water pump 14, and an atomizing nozzle 1. The water inlet pipe of the water pump 14 is connected to the water storage container, and the water outlet pipe is connected to the atomizing nozzle. The water pump 14 compresses and stretches the air in the pump chamber (fixed volume) through a mechanical device. Under the action of a one-way valve, a positive pressure is generated at the water outlet (the actual output pressure is related to the resistance of the pump outlet and the pump characteristics). A vacuum is formed at the water inlet, thereby sucking water out of the water storage container 7 and spraying it out of the atomizing nozzle 1. The atomizing nozzle 1 can adjust the pressure by rotating the nozzle or changing the nozzle type to form a wide-angle diffuse spray, thereby achieving coverage of the dust spraying range. Parameters such as spray distance and droplet size can also be adjusted according to actual conditions.

[0039] In this embodiment, if Figure 8 As shown, the crushing device 6 is mainly composed of high-carbon steel blades and a rotating shaft, which is installed inside the ash storage container. The high-carbon steel blades are symmetrically welded on the surface of the rotating shaft. The high-carbon steel blades are driven to rotate by the rotation of the rotating shaft, thereby breaking up the wood ash blocks and avoiding powder discharge blockage caused by wet and agglomerated wood ash.

[0040] In this embodiment, if Figure 9 As shown, a proper amount of plant ash is poured into the ash storage container 5, and the crushing device 6 and the ash spraying device are started. If it is determined that there is no crop in the soil at this time, the ash spraying device is used as the head when the device is operated; if it is determined that the spinach is in the seedling stage, to prevent the plant ash from sticking to the leaves and causing damage to the seedlings, the air blower is activated to blow away the ash stuck to the leaves, and the ash spraying device is used as the head when the device is operated; if it is determined that the spinach is in the mature stage, to better prevent insects and provide nutrients, the plant ash needs to stick to the leaves, and the spraying device is activated at this time. The device is operated with the spraying device as the head to first moisten the leaves and then spray the plant ash.

[0041] Theory and practice have proved that the machine in this example sprays the wood ash evenly during operation. For spinach in the seedling stage, the machine can blow away the wood ash sprinkled on the leaves of the seedlings, and for spinach in the mature stage, the machine can make the wood ash stick to the leaves, thus achieving the expected use effect.

[0042] To sum up, this product analyzes the current status of wood ash application, combines the crop characteristics of the entire spinach growth cycle, and aims to distinguish the contradiction between the high labor intensity and poor ash spreading effect of previous manual ash spreading. It is designed according to local conditions to be an intelligent wood ash sprayer suitable for the entire spinach growth cycle. It has a compact size, simple operation and good adaptability.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
