Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery cleaning technology, and in particular to a cleaning device for agricultural machinery. Background Technology

[0002] ① Traditional agricultural machinery often has a lot of mud and oil on its body after operation, making cleaning a necessary step. The conventional practice is to drive the agricultural machinery away from the work site and move it to a fixed water source and hardened ground area (such as a car wash or a cement floor near a water tap) for washing. This moving process itself has obvious drawbacks: the large machinery covered with thick mud and dirt will inevitably spill loose mud and sewage while driving, especially on unpaved field roads or public roads. This scattered mud and dirt will pollute the road surface, increase the extra cleaning burden, affect environmental hygiene, and may even cause safety risks such as slippery roads. The secondary pollution caused by the mobile washing process itself is a technical problem that urgently needs to be solved in the existing common methods.

[0003] ② To address the road pollution problem caused by mobile cleaning, a type of mobile cleaning equipment has been developed in the existing technology. For example, a suction pump driven by a gasoline engine or electric motor is used. This equipment is designed to be independent of the parking location of the machinery. Users can transport this cleaning unit to the agricultural machinery that needs cleaning and park it nearby. By connecting to a water source (such as a nearby pond, ditch, or bucket), high-pressure washing can be carried out on the spot. The core improvement of this method is that the cleaning equipment actively moves to the side of the agricultural machinery, avoiding the need for the large, muddy agricultural machinery to be cleaned to move itself. In this way, the agricultural machinery no longer needs to move a long distance in a muddy state before and during cleaning, thus effectively avoiding the problem of mud and dirt scattering and polluting the road surface along the way during its movement. Essentially, this solves the aforementioned technical problem.

[0004] ③ However, the aforementioned technical solution of placing the cleaning unit next to the agricultural machinery for on-site pumping cleaning, while successfully avoiding mobile pollution, introduces new operational limitations and complexities. Specifically, the suction pump of the cleaning unit needs to be stably placed on the ground near a water source for pumping operations; if the agricultural machinery happens to be parked several meters away from the bank of a natural water source (such as a pond), or if water needs to be pumped from a deeper part of the water body, the suction pump cannot be flexibly moved with the water source; its fixed ground support method determines that the suction pump cannot pump itself and its core components such as the power unit. The equipment is placed directly on the water surface, meaning it can only be located on dry ground near the shore. This necessitates connecting a long water inlet pipe to the suction connector, extending into the water. To accommodate varying distances between the agricultural machinery's parking location and the water source, flexible water inlet pipes of different lengths (usually quite long) are required, necessitating on-site laying, connection, retraction, and transportation. Excessively long inlet pipes not only significantly increase the size and weight of the equipment, making transport cumbersome and inconvenient, but also increase the complexity and time consumption of on-site deployment and storage, and potentially increase the risk of pipe blockage, leakage, or wear. Therefore, this reliance on long, extended pipes represents a new and specific technical drawback of this in-situ cleaning solution that avoids mobile contamination. Utility Model Content

[0005] The purpose of this utility model is to provide a cleaning device for agricultural machinery, which solves the technical problems of existing mobile cleaning units that cannot directly adapt to the water surface environment because the suction pump is fixed to the ground support, resulting in the need to rely on long pipelines for water extraction, which leads to inconvenience in equipment carrying, complex pipeline deployment, and limited operational flexibility.

[0006] To achieve the above objectives, this utility model provides a cleaning device for agricultural machinery, comprising two rubber tubes. An inflation connector is fixedly installed at the middle of the top of each rubber tube. Two support plates are symmetrically arranged on both sides of the rubber tubes along the length direction of the inflation connector. The support plates are respectively attached to the bottom of the cleaning component. The cleaning component includes a base plate. The base plate and the support plates are respectively attached, and two pins pass through the attachment points. The pins are respectively fixedly installed in the clamping frame. After the pins pass through, they rotate to clamp and fix the base plate and the support plate respectively.

[0007] The bottom plate has a box fixedly installed on its top, a heat dissipation window is provided on one side of the box, and a power cord is fixedly installed on the side of the box away from the heat dissipation window.

[0008] An oil filling cylinder is fixedly installed at a location adjacent to the power cord of the enclosure. A door is installed on the side of the enclosure opposite to the oil filling cylinder via a hinge. Hooks are fixedly installed at the four corners of the top of the enclosure.

[0009] A suction pump is bolted to the top center of the housing. The suction pump has a suction connector at the suction end and a pumping connector at the pumping end.

[0010] A diesel generator is fixedly installed on one side of the box, a battery pack is fixedly installed on the side of the box adjacent to the diesel generator, and a rectifier is fixedly installed on the side of the box adjacent to the battery pack.

[0011] The corresponding interfaces between the battery pack, rectifier, diesel generator, suction pump, and power line are connected by flexible wires.

[0012] The core innovation of this utility model is its unique detachable support structure and dual operation mode switching capability. The device includes two symmetrically arranged rubber tubes, with a dedicated inflation connector fixedly installed at the top center of the tubes. When an external air source injects gas into the tubes through the inflation connector, the tubes fully expand and transform into elastic supports with load-bearing capacity. A support plate extends from each side along the length of the inflation connector, and the two support plates form a symmetrical support structure. The upper surfaces of these support plates fit tightly against the bottom plate of the cleaning assembly to form a stable contact surface. Two pins are installed through the contact area between the support plates and the bottom plate. The pins are fixed in specific positions inside the clamping frame. Rotating the pins can drive the clamping frame to generate mechanical clamping force, firmly pressing and locking the support plates and the bottom plate into a single structure. Conversely, rotating the pins in the opposite direction can release the clamping force, allowing the two to separate quickly. This design forms a dual-function structure: when the tubing is inflated and clamping is complete, the entire device forms a floating unit that can be placed directly on the water surface for operation; after the clamping frame is disassembled, the cleaning assembly can be used independently as a ground device.

[0013] This structure solves the problem of the equipment's single operating mode—the buoyancy support of the tubing eliminates the absolute dependence on the shore base, allowing the cleaning components to float directly on the water surface, fundamentally shortening the water extraction distance; the detachable clamping frame connection gives the equipment flexible disassembly and reassembly capabilities, allowing free switching between floating and ground operation modes. The elasticity of the expanded tubing combined with the rigid locking effect of the clamping frame gives the device anti-bump stability in the floating state, while retaining reliable support function for ground operation after disassembly; the dual structure works together to ultimately achieve the core effects of "shortening the water inlet pipeline, reducing the burden of transportation, and adapting to complex water source terrain," overcoming the technical obstacles of traditional equipment caused by fixed support forms, such as long pipelines and cumbersome movement.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-5 .

[0023] This utility model provides a cleaning device for agricultural machinery, comprising two rubber tubes 101. An inflation connector 102 is fixedly installed at the center of the top of each rubber tube 101. The inflation connector 102 is used to inject gas into the rubber tube 101. When gas is injected, the rubber tube 101 expands to form a buoyant support structure. This design allows the entire cleaning device to float stably on the water surface. Two support plates 103 extend symmetrically from both sides of the rubber tube 101 along the length of the inflation connector 102. The support plates 103 are tightly fitted to the bottom plate 105 at the bottom of the cleaning assembly 104. Two pins 106 passing through the fitting points are fixedly installed inside a clamping frame 107. Rotating the pins 106 drives the clamping frame 107 to clamp the support plates 103 and the bottom plate 105. 5. A mechanical clamping action is formed to achieve a rigid connection between the cleaning component 104 and the support structure of the tubing 101; when the pin 106 is rotated in the opposite direction, the clamping frame 107 releases the clamping force, which can separate the cleaning component 104 from the tubing 101, making it easy to switch the operation mode; a closed box 108 is fixedly installed on the top of the bottom plate 105 of the cleaning component 104, and a heat dissipation window 109 is opened on one side of the box 108 to dissipate the heat generated by the operation of the equipment and ensure the stable operating temperature of the internal components; a power line 110 is fixedly led out from the side of the box 108 away from the heat dissipation window 109 for connecting to the external mains power; an oil filling cylinder 111 is fixedly installed at the position adjacent to the box 108 and the power line 110, which provides a fuel supply channel for the diesel generator 117. A hinged, closable door 112 is installed on the opposite side of the housing 108 and the oil filling cylinder 111, facilitating personnel to inspect and maintain the internal equipment. Hooks 113 are fixedly installed at the four corners of the top of the housing 108 as load points for hoisting and handling. A suction pump 114 is vertically installed at the center of the top of the housing 108 via bolts. The suction end of the suction pump 114 is connected to a suction connector 115 for drawing in water, and the pumping end is connected to a pumping connector 116 for outputting high-pressure water flow for cleaning. The interior of the housing 108 is divided into three functional areas: a diesel generator 117 is fixedly installed on one side to generate electricity by burning diesel supplied by the oil filling cylinder 111; a battery pack 118 is fixedly installed in the adjacent area to store electrical energy and drive the load; and a rectifier 119 is fixedly installed in the area adjacent to the battery pack 118 to handle current compatibility. The battery pack 118, rectifier 119, diesel generator 117, suction pump 114 and power line 110 are all electrically connected by flexible wires: when there is mains power, the input current of power line 110 charges the battery pack 118 and drives the suction pump 114; when the mains power is disconnected, the output current of diesel generator 117 is converted by rectifier 119 and charges the battery pack 118, and the battery pack 118 maintains the continuous operation of suction pump 114.

[0024] In this embodiment: when the rubber tube 101 is inflated, the device floats on the water surface, and the suction connector 115 directly draws water from the source below; after the clamping frame 107 is removed, the cleaning assembly 104 is placed on the ground alone, and the suction connector 115 draws water from a distant source through an extension pipe. The power system automatically switches between mains charging and diesel generator power supply logic according to the environment to ensure that the suction pump 114 continuously provides cleaning power.

[0025] Working principle: First, in terms of support, the two rubber tubes 101 provide a foundation; air is inflated into the rubber tubes 101 through the air inlet 102 at the top, causing the rubber tubes 101 to expand; this expansion not only gives the rubber tubes 101 a certain shock absorption effect to adapt to irregular ground, but more importantly, when the device is used near a water source, the expanded rubber tubes 101 can stably support the entire cleaning assembly 104 (including the housing 108, the suction pump 114, etc.) and float it on the water surface; at this time, the suction inlet 115 can be directly extended into the water below through a pipe to perform water pumping operations; on the other hand, if it needs to be used on flat ground or far away from the water source, the clamp frame 107 can be disassembled (by rotating the pin 106 to loosen the clamp), so that the bottom plate 105 of the cleaning assembly 104 is separated from the support plate 103; then, the cleaning assembly 104 (mainly the housing 108 and the suction pump 114) can be placed on the ground alone, at which time the suction inlet 115 is connected to a long pipe extending to the water source for water pumping. This enables two convenient operating modes: floating water pumping and ground-based water pumping, greatly expanding the application range. Energy supply is the key to driving the suction pump 114. The device is designed with an intelligent energy management strategy to adapt to different working conditions. When there is available mains power near the work site, an external power source is connected via power line 110. The connected current is prioritized for charging the battery pack 118, and a stable power is output directly from the battery pack 118 to drive the suction pump 114 when it is fully charged or simultaneously. This mode prioritizes the use of the external power grid, making it quiet and economical. However, in outdoor environments far from mains power, external power is unavailable, so the backup power supply mode is activated. The operator adds diesel fuel to the diesel generator 117 from the fuel filler 111, starts the diesel generator 117, and the power output from the diesel generator 117 is processed by the rectifier 119 (rectifying and regulating the potentially unstable AC power output from the generator into a more stable DC power suitable for charging the battery pack 118 and using the equipment), and then input into the battery pack 118 for storage and buffering. The battery pack 118 then supplies power to the suction pump 114, enabling it to run continuously for water pumping and cleaning. This design ensures that even without mains power, the self-contained diesel generator 117 can reliably supply power to maintain uninterrupted cleaning operations. The internal components of the entire energy system (diesel generator 117, battery pack 118, rectifier 119, suction pump 114, and power cord 110 interface) are connected by flexible wires, working smoothly together. In addition, the device emphasizes long-term operational reliability.A heat dissipation window 109 is provided on one side of the housing 108 to effectively dissipate the heat accumulated inside the housing when the diesel generator 117 is running or the battery pack 118 is discharging at high current, preventing overheating from damaging electrical components and ensuring system stability. The oil filling cylinder 111 installed on the housing 108 facilitates the periodic replenishment of fuel to the diesel generator 117 and the addition of lubricating oil to related moving parts, reducing wear and extending service life. The hook 113 on the top of the housing 108 provides a lifting fulcrum, facilitating the transportation and movement of the entire device and increasing portability. In summary, this agricultural machinery cleaning device achieves flexible dual-mode operation on water surface / ground through a clever air cylinder expansion support, and uses a suction pump 114 to complete the core water pumping and rinsing. Its core value lies in the innovative energy switching mechanism (mains charging drive and diesel generator drive) to ensure reliable operation in various power environments. Combined with heat dissipation, maintenance and convenient mobility design, it forms a durable, efficient and self-sustaining cleaning solution that adapts to complex agricultural operating environments, significantly improving the efficiency and convenience of agricultural machinery maintenance.
