Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, in particular to a spraying device for agricultural soil treatment. Background Art

[0002] Agricultural soil treatment sprayers are a type of agricultural machinery specifically designed to improve soil quality and address soil problems such as pollution, compaction, and nutrient imbalance. They regulate and repair soil structure, fertility, and health by evenly spraying specific chemicals, fertilizers, amendments, or microbial agents onto the soil surface or deep within.

[0003] Currently, most agricultural soil treatment sprayers are equipped with only a single nozzle. This single-nozzle design results in extremely low spraying efficiency. When operating on large farmland, spraying requires a significant amount of time, requiring a significant back-and-forth movement, severely impacting work progress. Furthermore, the short spraying range of a single nozzle limits its coverage, making it difficult to meet the soil treatment needs of large-scale farmland. Furthermore, since a single nozzle can only spray in a single direction, it cannot simultaneously spray all four sides. In practice, the device's position must be constantly adjusted to achieve comprehensive coverage, increasing operational complexity and workload. Existing sprayers are limited in functionality, possessing only the spraying function and failing to perform post-spray soil turning operations. Soil treatment often requires post-spraying soil turning to ensure thorough mixing of the agent and enhance the treatment effect. Existing agricultural soil treatment sprayers fail to meet this continuous operation requirement, resulting in a cumbersome operation process and the need for multiple devices, increasing agricultural production costs and making equipment scheduling more difficult. Therefore, a need exists for an agricultural soil treatment sprayer that overcomes these challenges and combines multi-directional spraying with soil turning. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a spraying device for agricultural soil treatment, which can turn the soil while spraying pesticides in multiple directions.

[0005] The purpose of the present invention is achieved by adopting the following technical solutions:

[0006] A spraying device for agricultural soil treatment comprises: a frame, a spraying mechanism and a soil turning mechanism; the spraying mechanism comprises a support, a pipeline, a water pump, a water tank and a plurality of universal water spray pipes; the support and the water tank are both mounted on the frame, the water tank, the pipeline and the universal water spray pipe are sequentially connected along the direction of water flow, and the pipeline is connected to the water pump; the plurality of universal water spray pipes are mounted on the support, and the plurality of universal water spray pipes are distributed at intervals along the horizontal circumference of the support; the soil turning mechanism is mounted on the frame, and is used to turn over the soil after spraying by the spraying mechanism.

[0007] Furthermore, the vehicle frame is equipped with a lifting drive mechanism, the lifting output portion of the lifting drive mechanism is connected to a lifting platform, the lifting platform is equipped with a motor, and the motor is drivingly connected to the soil turning mechanism.

[0008] Furthermore, the vehicle frame is provided with a accommodating space, which extends upward from the top of the vehicle frame, and the soil turning mechanism can be accommodated in the accommodating space.

[0009] Furthermore, the spraying device for agricultural soil treatment also includes a transmission mechanism, which includes a driving wheel, a transmission belt and a driven wheel. The motor, the driving wheel, the transmission belt, the driven wheel and the soil turning mechanism are sequentially connected in transmission.

[0010] Furthermore, the frame is pivotally connected to a wheel, and the frame is connected to a push handle.

[0011] Furthermore, the water tank is equipped with a stirrer, and the stirrer is used to stir the medicine.

[0012] Furthermore, one of the base and the frame is provided with a horizontal guide rail, and the other is provided with a slider, and the horizontal guide rail and the slider are in sliding engagement.

[0013] Furthermore, the horizontal guide rail is magnetically engaged with the slider.

[0014] Furthermore, the horizontal guide rail extends along a horizontal direction perpendicular to the traveling direction of the frame.

[0015] Furthermore, the universal water spray pipe is composed of a plurality of universal joints; or, the universal water spray pipe is made of rubber material.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Under the action of the water pump, the liquid in the water tank is pumped out and forms a water flow with a certain pressure. Because the pipeline is connected to multiple universal water spray pipes in sequence along the direction of water flow, the pressurized water flow is transmitted through the pipeline to the universal water spray pipes. Multiple universal water spray pipes are spaced horizontally around the support, and can spray water in different directions around the support. By adjusting the angle of the universal water spray pipes, the soil in different areas and at different angles can be evenly sprayed, thus evenly covering the soil surface with the liquid required for soil treatment, completing the soil spraying operation.

[0018] 2. The turning mechanism uses its own multiple curved turning plates to turn over the soil that has just been sprayed by the spraying mechanism. The curved surface design of the curved turning plates can produce a squeezing and shearing effect similar to a "wedge". When the turning mechanism rotates, the curved plates cut into the soil, and the friction between the curved surface and the soil particles will force the soil to slide along the curved surface, thereby breaking up larger clods of soil. During the turning process, the turning mechanism mixes the surface soil containing the treatment liquid with the lower soil, so that the soil treatment liquid can more fully contact the soil particles, accelerate the soil treatment process, promote the improvement of soil structure and the uniform distribution of nutrients, and ultimately achieve better soil treatment effects. After turning and mixing, the soil porosity increases, and air and moisture can more easily penetrate deep into the soil layer, alleviating the problem of surface compaction, thereby providing a more suitable environment for plant root growth.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See also Figures 1-4 A preferred embodiment of the present invention is a spraying device for agricultural soil treatment, comprising: a frame 1, a spraying mechanism 2 and a soil turning mechanism 3; the spraying mechanism 2 comprises a support 21, a pipe 22, a water pump 23, a water tank 24 and a plurality of universal water spray pipes 25; the support 21 and the water tank 24 are both mounted on the frame 1, the water tank 24, the pipe 22 and the universal water spray pipe 25 are sequentially connected along the direction of water flow, and the pipe 22 is connected to the water pump 23; a plurality of universal water spray pipes 25 are mounted on the support 21, and the plurality of universal water spray pipes 25 are distributed at intervals along the horizontal circumference of the support 21; the soil turning mechanism 3 is mounted on the frame 1, and the soil turning mechanism 3 is used to turn over the soil after spraying by the spraying mechanism 2, and the soil turning mechanism 3 comprises a roller 31 and a plurality of arc-shaped soil turning plates 32.

[0028] The support 21 and the water tank 24 are both mounted on the frame 1, and a plurality of universal water spray pipes 25 are mounted on the support 21, so that the support 21 and the water tank 24 form a rigid connection with the frame 1 to withstand the bumps and vibrations of the vehicle during travel, and avoid the displacement of the spraying position of the universal water spray pipe 25 or the loosening of the pipe 22 interface due to shaking, which is particularly suitable for operation under complex road conditions such as field dirt roads and construction sites. A plurality of universal water spray pipes 25 are distributed at intervals along the horizontal circumference of the support 21 (such as evenly distributed around the circular support), and a circular spraying area can be formed in the plane to ensure full circumferential coverage of the direction of travel of the frame 1. For example: in an agricultural scenario, both sides of the crop row or the surrounding weeds can be evenly sprayed at the same time, avoiding the problem of missed spraying caused by traditional unilateral spraying. The water tank 24, the pipe 22, and the universal water spray pipe 25 are sequentially connected along the direction of water flow. The pipe 22 is connected to the water pump 23; this provides a power source and allows the water pressure to be adjusted according to demand. When the agricultural soil treatment spraying device is in operation, the water pump 23 is activated and begins to operate. Under the action of the water pump 23, the liquid in the water tank 24 is pumped out, forming a water flow with a certain pressure. Because the pipe 22 is sequentially connected to the multiple universal water spray pipes 25 along the direction of water flow, the pressurized water flow is transmitted through the pipe 22 to the universal water spray pipes 25. The multiple universal water spray pipes 25 are spaced horizontally around the support 21, capable of spraying water in different directions around the support 21. By adjusting the angles of the universal water spray pipes 25, the soil can be evenly sprayed in different areas and at different angles, thereby evenly covering the soil surface with the liquid required for soil treatment, completing the soil spraying operation. After the spraying mechanism 2 completes spraying the soil, the turning mechanism 3 installed on the frame 1 is started. The turning mechanism 3 turns over the soil that has just been sprayed by the spraying mechanism 2 through its own multiple arc-shaped turning plates 32. The curved surface design of the arc-shaped turning plates can produce a squeezing and shearing effect similar to a "wedge". When the turning mechanism rotates, the arc-shaped plates cut into the soil, and the friction between the curved surface and the soil particles will force the soil to slide along the curved surface, thereby breaking up larger clods of soil. During the turning process, the turning mechanism 3 mixes the surface soil containing the treatment liquid with the lower soil layer, so that the soil treatment liquid can more fully contact the soil particles, accelerate the process of soil treatment, promote the improvement of soil structure and the uniform distribution of nutrients, and ultimately achieve better soil treatment effects. After turning over and mixing, the soil porosity increases, and air and moisture can more easily penetrate into the deep soil layer, alleviating the problem of surface compaction, thereby providing a more suitable environment for the growth of plant roots.

[0029] Preferably, in this embodiment, the frame 1 is equipped with a lifting drive mechanism 5, the lifting output portion of the lifting drive mechanism 5 is connected to a lifting platform 6, the lifting platform 6 is equipped with a motor 7, and the motor 7 is driven and connected to the turning mechanism 3. In this way, the lifting drive mechanism 5 controls the lifting and lowering of the lifting platform 6, and can accurately adjust the height position of the motor 7 and the turning mechanism 3. In different soil management scenarios, the turning depth can be flexibly set according to actual needs. For example, for newly developed soil, the turning depth can be appropriately increased; and for soil that has been conventionally cultivated, the turning depth can be reduced to avoid excessive tillage that damages the soil structure, thereby meeting the diverse requirements of agricultural soil management operations and improving the scientificity and effectiveness of management. The lifting drive mechanism 5 can be a cylinder lifting drive, an electric push rod lifting drive, or a worm gear lifting drive mechanism.

[0030] Preferably, in this embodiment, the frame 1 is provided with a housing space 11 extending upward from the top of the frame 1, and the tilling mechanism 3 can be accommodated within the housing space 11. This configuration provides storage space 11 for the tilling mechanism 3, preventing collisions and scrapes between the tilling mechanism 3 and external objects during transportation and storage, thereby preventing deformation and damage to its components. Furthermore, this configuration reduces the erosion of the tilling mechanism 3 by external debris such as dust, dirt, and rainwater, lowering the risk of component failures due to moisture, rust, and blockage, thereby extending the service life of the tilling mechanism 3 and reducing equipment maintenance and replacement costs.

[0031] Preferably, in this embodiment, the agricultural soil treatment spraying device further comprises a transmission mechanism 4, wherein the transmission mechanism 4 comprises a driving wheel 41, a transmission belt 42 and a driven wheel 43, wherein the motor 7, the driving wheel 41, the transmission belt 42, the driven wheel 43 and the soil turning mechanism 3 are sequentially connected in transmission. With this arrangement, the motor 7 is sequentially connected in transmission with the soil turning mechanism 3 via the driving wheel 41, the transmission belt 42 and the driven wheel 43, and the power generated by the motor 7 can be smoothly and efficiently transmitted to the soil turning mechanism 3. The transmission belt 42 has a certain elasticity during the transmission process, which can buffer the instantaneous impact force generated when the motor 7 is started and operated, avoid damage to the soil turning mechanism 3 due to sudden changes in force, ensure the continuity and stability of the soil turning operation, enable the soil turning mechanism 3 to always work at a suitable speed and torque, and effectively improve the quality and efficiency of the soil turning operation. The transmission mechanism can also be a chain drive or a gear drive.

[0032] Preferably, in this embodiment, the frame 1 is pivotally connected to wheels 13, which are connected to a push handle 12. This arrangement, with the frame 1 pivotally connected to the wheels 13, allows the entire spraying device to be easily moved around work sites such as farmland. The rolling friction of the wheels 13 is much less than the sliding friction, allowing the operator to move the device between different areas by applying only a small amount of force to push the push handle 12. Compared to sliding devices without wheels 13, this significantly reduces labor consumption and is particularly suitable for soil remediation work on large farmland areas, effectively improving operational efficiency and reducing labor intensity.

[0033] Preferably, in this embodiment, the water tank 24 is equipped with an agitator 8, and the agitator 8 is used to stir the agent. With this arrangement, the agitator 8 can continuously stir the agent in the water tank 24, which can effectively break the concentration difference between the various components of the agent and avoid stratification, local excessive or low concentration. Whether it is the compounding of multiple chemical agents or the mixing of fertilizers and water, they can be fully blended under the action of the agitator 8 to form a uniform and stable mixture. In this way, when spraying, each area of the soil can receive a consistent concentration of agent, making the soil treatment effect more balanced and significantly improving the overall quality of soil treatment.

[0034] Preferably, in this embodiment, one of the base and the frame 1 is provided with a horizontal guide rail 14, and the other is provided with a slider 211, and the horizontal guide rail 14 and the slider 211 are slidably engaged. Through the sliding engagement of the horizontal guide rail 14 and the slider 211, the operator can flexibly and accurately adjust the position of the spraying mechanism 2 according to actual operational requirements. When treating farmland with irregular shapes or special areas (such as ridge gaps or crop edges), the spraying mechanism 2 can be precisely moved to the target area, ensuring that the universal water spray pipe 25 is sprayed at the optimal angle and position, avoiding waste of pesticides, reducing pollution to non-target areas, and significantly improving the accuracy and targeting of soil treatment.

[0035] Preferably, in this embodiment, the horizontal guide rail 14 and the slider 211 are magnetically coupled. This arrangement allows the slider 211 to be firmly attached to the horizontal guide rail 14 by magnetic force after the spraying mechanism 2 moves to the target position, preventing the slider 211 from accidentally sliding due to vibrations, external force collisions, and other factors during operation, thereby ensuring that the spraying mechanism 2 always remains in the preset position. For example, when the tillage mechanism 3 generates vibrations during operation, or when the device moves on uneven ground, the stabilizing effect of the magnetic attraction can prevent the spraying direction from shifting, ensuring accurate spraying of the agent, and significantly improving the accuracy and stability of the soil treatment operation.

[0036] Preferably, in this embodiment, the horizontal guide rail 14 extends in a horizontal direction perpendicular to the direction of travel of the frame 1. The horizontal guide rail 14 extends in a direction perpendicular to the direction of travel of the frame 1, so that the spraying mechanism 2 can move freely in this direction, effectively expanding the lateral spraying coverage. When the frame 1 moves longitudinally along the farmland, the spraying mechanism 2 can adjust its position laterally through the horizontal guide rail 14 to achieve spraying operations on a wider area during a single movement, reducing the number of repeated movements. For example, when operating on a large area of farmland, there is no need to frequently adjust the direction of travel of the frame 1, and soil treatment of the entire farmland can be completed quickly, significantly improving work efficiency and saving work time and labor costs.

[0037] Preferably, in this embodiment, the universal water spray pipe 25 comprises multiple universal joints; alternatively, the universal water spray pipe 25 is made of rubber. This combination of universal joints provides the universal water spray pipe 25 with exceptional flexibility, allowing operators to precisely and conveniently adjust the spraying angle and direction of the universal water spray pipe 25 to suit varying soil treatment needs. Whether it's targeted spraying in specific areas such as field edges and around obstacles, or adjusting the spraying height to accommodate varying crop heights, these features can be easily achieved. This significantly improves spraying accuracy, avoids pesticide waste and blind spots, and enhances soil treatment effectiveness. The universal water spray pipe 25 is made of rubber, a material with excellent flexibility. This prevents bending and breaking during frequent adjustments to its angle and direction, ensuring long-term operation. Even in cold environments, the rubber material maintains a certain degree of flexibility and does not become hard or brittle due to low temperatures. This ensures that the universal water spray pipe 25 can operate normally in different seasons and climates, enhancing equipment reliability.
