Description
Technical Field
[0001] The utility model relates to the technical field of spraying equipment, in particular to a spraying equipment for agriculture. Background Art
[0002] In the field of agricultural disease control, spraying equipment plays a crucial role and is a key tool to ensure the healthy growth of crops and effectively resist the invasion of diseases. Its working principle is usually to stably transport the prepared high-pressure liquid medicine through a water delivery pipeline, and finally reach the spraying pipe, and realize high-pressure spraying with the help of the spraying pipe, so that the liquid medicine evenly covers the surface of the crops, so as to achieve the purpose of preventing and controlling diseases.
[0003] However, when the existing spraying equipment is in an unused state for a long time, the spraying pipe is extremely vulnerable to the interference of the external environment. Since the agricultural operation environment is usually relatively complex, tiny particles such as dust and gravel are everywhere. Under the action of natural wind force, gravity and other factors, these dust and gravel are very easy to enter the inside of the spraying pipe and gradually accumulate. As the blockage increases, once it accumulates to a certain extent, it will seriously affect the spraying effect of the liquid medicine. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a spraying equipment for agriculture, which has the advantage of anti-blocking, and solves the problem that the spraying pipe of the existing spraying equipment is often blocked by external dust and gravel when it is not used for a long time.
[0005] The utility model provides the following technical scheme: a spraying equipment for agriculture, including a water delivery pipeline, the top surface of the water delivery pipeline is evenly threadedly connected with spraying pipes, anti-blocking components are arranged inside the spraying pipes, rotating components are arranged inside the spraying pipes, the anti-blocking components include anti-blocking covers arranged on the top surface of the spraying pipes, anti-blocking grooves are opened on the bottom surface of the anti-blocking covers, conical heads are fixedly connected to the bottom surface of the anti-blocking covers, connecting frames are fixedly connected to the inner wall surface of the spraying pipes, connecting rods are slidably connected inside the connecting frames, limiting plates are rotatably connected to the bottom surface of the connecting rods, and extrusion springs are fixedly connected between the top surface of the limiting plates and the bottom surface of the connecting frames. The water delivery pipeline is the main channel for liquid medicine transportation, responsible for stably and evenly transporting the prepared high-pressure liquid medicine from the source to each spraying pipe, providing a basic guarantee for the liquid medicine supply for the entire spraying operation.
[0006] Preferably: the anti-blocking cover is movably connected to the top surface of the spraying pipe, and the anti-blocking cover is clamped to the top edge of the spraying pipe through the anti-blocking groove. The spraying pipe receives the liquid medicine from the water delivery pipeline, further transports it to the spraying operation area, and provides an installation space for the anti-blocking components and the rotating components, so that these components can play their normal roles inside the spraying pipe.
[0007] Preferably, the conical head is slidably connected inside the spraying pipe, and the top surface of the connecting rod is fixedly connected to the bottom surface of the conical head. Under the action of water pressure, the conical head overcomes its own gravity and the friction with the inner wall of the spraying pipe, and slides upward along the inner wall of the spraying pipe, thereby driving the movement of components such as the connecting rod, realizing the jacking of the anti-blocking cover and the exposure of the spraying groove.
[0008] Preferably, the limiting plate is arranged directly below the connecting frame, the conical head is arranged directly above the connecting frame, and the compression spring is sleeved on the surface of the connecting rod. The compression spring is sleeved on the surface of the connecting rod and is compressed by the limiting plate under the action of water pressure to store elastic potential energy. When the water pressure disappears, the stored elastic potential energy is released, pushing the limiting plate to move downward to realize the reset of each component of the anti-blocking assembly, and making preparations for the next spraying operation.
[0009] Preferably, the rotating assembly includes spraying grooves uniformly opened on the bottom surface of the conical head. The bottom surface of the conical head is fixedly connected with a conical lifting member. The spraying grooves are uniformly opened on the bottom surface of the conical head and are distributed in a circular shape as a whole to form a turbine structure. When high-pressure water flows through, a rotating force is generated due to the structural characteristics, making the water flow form a rotating spraying state, thereby expanding the spraying range, improving the uniformity of liquid medicine spraying, and enhancing the disease control effect.
[0010] Preferably, the spraying grooves are distributed in a circular shape on the bottom surface of the conical head, and the whole forms a turbine structure. Both ends of the conical lifting member are open, and the bottom opening of the conical lifting member is larger than its top opening. The conical lifting member is fixedly connected to the bottom surface of the conical head. Both ends are open and the bottom opening is larger than the top opening. After the liquid medicine enters the spraying pipe, it first impacts its bottom. Due to the gradually narrowing channel, according to the principle of fluid mechanics, the flow rate of the liquid medicine increases and the pressure increases to form high-pressure water flow, providing sufficient power for subsequent pushing of the conical head and realizing rotating spraying.
[0011] Compared with the prior art, the present utility model has the following beneficial effects:
[0012] 1. Through the setting of the anti-blocking assembly, when the spraying stops, the compression spring resets, pushing the conical head to slide downward and reset, and the anti-blocking cover is re-locked to the top edge of the spraying pipe, effectively preventing impurities from entering the inside of the spraying pipe. At the same time, when the liquid medicine flows through the spraying pipe, the conical head in the anti-blocking assembly can automatically slide upward under the action of water pressure, driving the connecting rod and the limiting plate to move upward. This process not only clears the blockage, but also realizes the self-cleaning of the spraying pipe through the sliding of the conical head and the jacking of the anti-blocking cover, ensuring the continuity and stability of the spraying operation.
[0013] 2. Through the setting of the rotating component, when high-pressure water flow passes through the spraying tank, a rotating force is generated due to the structural characteristics, causing the water flow to form a rotating spraying state. This rotating spraying method not only expands the spraying range but also enables the liquid medicine to cover the crops more evenly, improving the effect of disease control. At the same time, the spraying tank with a turbine structure reduces the waste of the liquid medicine and improves the utilization rate of the liquid medicine, bringing significant economic and environmental benefits to agricultural production.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: an agricultural spraying device, including a water delivery pipe 1, the top surface of the water delivery pipe 1 is uniformly threadedly connected with spraying pipes 2, anti-blocking components 3 are arranged inside the spraying pipes 2, and rotating components 4 are arranged inside the spraying pipes 2. The anti-blocking component 3 includes an anti-blocking cover 31 arranged on the top surface of the spraying pipe 2. An anti-blocking groove 32 is opened on the bottom surface of the anti-blocking cover 31. A conical head 33 is fixedly connected to the bottom surface of the anti-blocking cover 31. A connecting frame 34 is fixedly connected to the inner wall surface of the spraying pipe 2. A connecting rod 35 is slidably connected inside the connecting frame 34. A limiting plate 36 is rotatably connected to the bottom surface of the connecting rod 35. A compression spring 37 is fixedly connected between the top surface of the limiting plate 36 and the bottom surface of the connecting frame 34. The anti-blocking cover 31 is movably connected to the top surface of the spraying pipe 2. The anti-blocking cover 31 is clamped to the top edge of the spraying pipe 2 through the anti-blocking groove 32. The conical head 33 is slidably connected inside the spraying pipe 2. The top surface of the connecting rod 35 is fixedly connected to the bottom surface of the conical head 33. The limiting plate 36 is arranged directly below the connecting frame 34. The conical head 33 is arranged directly above the connecting frame 34. The compression spring 37 is sleeved on the surface of the connecting rod 35. Through the built-in anti-blocking component 3, automatic cleaning of the spraying pipe 2 and effective removal of blockages are realized. When the liquid medicine flows through the spraying pipe 2, the conical head 33 in the anti-blocking component 3 automatically slides upward under the action of water pressure, driving the connecting rod 35 and the limiting plate 36 to move upward, and the compression spring 37 is compressed to store elastic potential energy. During this process, the blockages are effectively removed, and at the same time, the spraying pipe 2 realizes self-cleaning. When the water flow stops, the compression spring 37 resets, pushing the conical head 33 to slide downward and reset, and the anti-blocking cover 31 is re-clamped to the top edge of the spraying pipe 2, effectively preventing impurities from entering again. It not only solves the problem that the existing spraying equipment is easy to block, but also improves the stability and service life of the equipment, providing a more reliable and efficient spraying solution for agricultural production. The anti-blocking cover 31 is clamped to the top edge of the spraying pipe 2 through the anti-blocking groove 32. When the equipment is not started, it effectively prevents external dust, sand and other impurities from entering the inside of the spraying pipe 2 and avoids the occurrence of blockage problems. After the equipment is started, when the conical head 33 slides upward under the action of water pressure, the anti-blocking cover 31 is lifted and gradually disengages from the top edge of the spraying pipe 2, creating conditions for the spraying of the liquid medicine. The anti-blocking groove 32 cooperates with the top edge of the spraying pipe 2 to realize the clamping of the anti-blocking cover 31, ensuring that the anti-blocking cover 31 can be stably fixed on the spraying pipe 2 when the equipment is idle and playing an anti-blocking role. The connecting frame 34 is fixedly connected to the inner wall surface of the spraying pipe 2, providing a sliding track for the connecting rod 35, ensuring that the connecting rod 35 can stably slide along a specific direction and guaranteeing the coordinated movement of the various components of the anti-blocking component 3. The top of the connecting rod 35 is fixedly connected to the conical head 33, and the bottom is rotatably connected to the limiting plate 36, transmitting the water pressure force received by the conical head 33 to the limiting plate 36 and driving the limiting plate 36 and the compression spring 37 to move.
[0020] Please refer toFigure 1 - Figure 3 The rotating assembly 4 includes spraying grooves 41 uniformly formed on the bottom surface of the conical head 33. A conical lifting member 42 is fixedly connected to the bottom surface of the conical head 33. The spraying grooves 41 are circumferentially distributed on the bottom surface of the conical head 33 and form a turbine structure as a whole. Both ends of the conical lifting member 42 are open, and the bottom opening of the conical lifting member 42 is larger than its top opening. The head of the conical lifting member 42 is sleeved on the bottom surface of the conical head 33, and a water flow channel is formed between the conical lifting member 42 and the spraying grooves 41. The rotating assembly 4 arranged inside the spraying pipe 2 generates a rotating force when the water flow passes through the spraying grooves 41 with a turbine structure uniformly formed at the bottom of the conical head 33, forming a rotating spraying state. This setting not only expands the spraying range but also enables the liquid medicine to cover the crops more evenly, improving the effect of disease control. Rotating spraying can make more effective use of the liquid medicine, reduce waste, and at the same time reduce environmental pollution.
[0021] Working principle: During the operation of agricultural disease control, the agricultural spraying device is started, and the liquid medicine is input from the water delivery pipe 1 and evenly distributed into each spraying pipe 2 threadedly connected to its top surface. After the liquid medicine enters the spraying pipe 2, it first impacts the bottom of the conical supporting member 42. Since both ends of the conical supporting member 42 are open and the bottom opening is larger than the top opening, when the liquid medicine passes through its interior, the channel gradually narrows. According to the principle of fluid mechanics, the flow rate of the liquid medicine increases and the pressure increases to form a high-pressure water flow. Then, the high-pressure water flow impacts the conical head 33 in the anti-clogging component 3 through the water flow channel formed between the conical supporting member 42 and the spraying groove 41. Under the action of the powerful water pressure, the conical head 33 overcomes its own gravity and the friction force with the inner wall of the spraying pipe 2, and cooperates with the thrust formed on the conical supporting member 42 under the action of the powerful water pressure, so that the conical supporting member 42 and the conical head 33 slide upward along the inner wall of the spraying pipe 2. At the same time, the connecting rod 35 fixedly connected to its bottom moves upward synchronously. The connecting rod 35 slides upward inside the connecting frame 34 fixedly connected to the inner wall of the spraying pipe 2. The limiting plate 36 fixedly connected to the bottom of the connecting rod 35 moves upward accordingly, squeezing the compression spring 37 fixedly connected between the top surface of the limiting plate 36 and the bottom surface of the lowermost connecting frame 34. The compression spring 37 is compressed to store elastic potential energy. During the upward sliding process of the conical head 33, the anti-clogging cover 31 movably connected to the top surface of the spraying pipe 2 and clamped to the top edge of the spraying pipe 2 through the anti-clogging groove 32 is lifted up and gradually separated from the top edge of the spraying pipe 2. At the same time, one end of the spraying groove 41 evenly opened on the bottom surface of the conical head 33 and distributed in a circular shape to form a turbine structure is also exposed from the top edge of the spraying pipe 2. Subsequently, the high-pressure water flow flows into the spraying groove 41 along the water flow channel formed between the conical supporting member 42 and the spraying groove 41 and moves along the spraying groove 41. Due to the turbine structure of the spraying groove 41, the water flow will generate a rotational force due to its structural characteristics when passing through, so that the water flow forms a rotational spraying state and finally sprays out from the spraying groove 41 to perform a large-area and uniform disease control spraying operation on the crops. When the water flow stops, the water pressure disappears, and the elastic potential energy stored in the compression spring 37 is released, pushing the limiting plate 36 to move downward. The limiting plate 36 drives the connecting rod 35 to slide downward inside the connecting frame 34, thereby making the conical head 33 slide downward along the inner wall of the spraying pipe 2 to reset. At the same time, the anti-clogging cover 31 also re-clamps to the top edge of the spraying pipe 2 with the reset of the conical head 33 to prevent impurities from entering the spraying pipe 2 and prepare for the next spraying operation.
