Description

Technical Field

[0001] The utility model relates to the technical field of washing and sweeping vehicles and floor scrubbers, and in particular to an automatic suction plate mechanism. Background Art

[0002] A floor sweeper and floor scrubber is a type of mechanical equipment used for cleaning urban roads, squares and industrial sites. Its working principle mainly relies on the negative pressure provided by the fan to suck garbage, dust and debris on the ground into the machine through the suction port. When the floor scrubber operator finds a large area of ​​leaves on the road ahead, he needs to manually adjust the ground clearance of the front baffle so that the garbage can smoothly enter the suction cup.

[0003] However, this manual adjustment method has obvious disadvantages: the operator needs to judge by himself when to adjust and reset the front baffle, which increases the complexity of the operation. At the same time, due to the need for manual intervention, the adjustment and resetting of the baffle may not be carried out in time, resulting in weakened suction of the suction cup on roads with more leaves. Failure to reset the front baffle in time will continue to affect the suction of the suction cup and reduce the cleaning efficiency of the floor scrubber, especially when encountering a large area of ​​leaf accumulation, leaves and debris will accumulate at the front end of the floor scrubber, making it difficult to ensure the thoroughness and efficiency of the cleaning.

[0039] Reference Figure 1-8 An automatic suction cup mechanism is proposed, including a suction cup body 1 and a collecting port 11 arranged on the suction cup body 1. The suction cup body 1 is also provided with a rolling sweep assembly 2. The rolling sweep assembly 2 is located in front of the suction cup body 1. The rolling sweep assembly 2 is used to guide the debris in the front to the collecting port 11.

[0040] The utility model configures a rolling sweeping assembly at the front end of the suction cup body, and when faced with accumulated debris, it can be broken down into smaller parts, and guided to the suction cup body one by one, and each part of the debris can be quickly and accurately guided into the collection port through the suction cup.

[0041] At the same time, the operator does not need to judge when to adjust and reset the front baffle, which greatly ensures the cleaning efficiency.

[0042] Optionally, the rolling sweep assembly 2 includes:

[0043] A connecting member 15, wherein the connecting member 15 is arranged on the suction cup body 1;

[0044] A support shaft 21, wherein the support shaft 21 is rotatably connected to the connecting member 15, and the support shaft 21 is connected to the suction cup body 1 through the connecting member 15;

[0045] At least two first baffles 22, wherein the first baffles 22 are evenly spaced and arranged on the surface of the support shaft 21;

[0046] In this embodiment, by providing a rolling sweep assembly in front of the suction cup body, the first baffle can automatically divide and transport large areas of garbage such as leaves.

[0047] Specifically, when a large amount of garbage and debris appears in front of the suction cup body, the first baffle will automatically rotate, split the large piece of garbage into smaller parts, and push them to the collection port through the rotation movement. As the first baffle continues to rotate, the segmented garbage is continuously guided to the collection port and sucked into the suction cup through the negative pressure inside the suction cup.

[0048] Preferably, the method of driving the first baffle to rotate can be expanded in various ways. For example, the mechanical structure in the rolling sweep assembly can be replaced with a driving device (electric motor, hydraulic motor, etc.) to provide a more stable and efficient driving force.

[0049] Preferably, the connection mode of the support shaft can also be improved, and it is no longer a simple mechanical connection, but a spring connection or a flexible shaft connection is adopted to adapt to different working environments and load changes.

[0050] Optionally, a negative pressure chamber 16 is further provided on the suction cup body 1 , and the negative pressure chamber 16 is located at the lower side of the suction cup body 1 , and one side of the negative pressure chamber 16 is opposite to the rolling sweep assembly 2 .

[0051] In this embodiment, compared with the design without a negative pressure chamber, the negative pressure chamber not only enhances the negative pressure effect of the suction cup to ensure that the garbage is effectively sucked in, but also acts as a baffle to prevent debris from being sucked away during the cleaning process.

[0052] Preferably, a flow channel or a guide plate may be added in the negative pressure chamber to further improve the negative pressure effect and adsorption efficiency.

[0053] Preferably, the shape of the negative pressure chamber can be designed to be a streamlined structure to reduce air resistance and increase the suction effect.

[0054] Preferably, the installation method of the negative pressure chamber can adopt a modular design to facilitate maintenance and replacement to adapt to different garbage types and cleaning requirements.

[0055] Specifically, the negative pressure chamber includes:

[0056] The suction module is in the shape of a square frame and is connected to the negative pressure chamber to ensure maximum suction efficiency of garbage;

[0057] The guide module includes a guide plate and a guide pipe, wherein the guide plate and the guide pipe are detachably connected in the negative pressure chamber, and the guide module is located behind the suction module, thereby optimizing the air flow path and enhancing the efficiency of garbage suction;

[0058] The filter module includes a multi-layer filter screen and a filter element. The filter screen and the filter element can be detachably connected to the collection port to prevent larger particles or debris from entering the fan, thereby protecting the equipment and improving the cleaning effect;

[0059] Sensing module: includes a detection sensor and a status indicator. The detection sensor and the status indicator are arranged on the top or side of the negative pressure chamber. The detection sensor is used to detect residual debris, and the status indicator is used to display the working status, which is convenient for regular inspection and maintenance to ensure long-term and efficient operation of the system.

[0060] Optionally, a second baffle 23 is further provided on the suction cup body 1 , and the rolling sweep assembly 2 is located in the second baffle 23 . The second baffle 23 covers the rolling sweep assembly 2 in a semi-sealed form to generate negative pressure in the rolling sweep assembly 2 .

[0061] In this embodiment, the semi-sealed design of the second baffle 23 can limit the air flow around the rolling sweep assembly to form a relatively closed space. When the fan in the suction cup body is working, the fan will draw air, causing the air pressure in this semi-sealed space to drop, thereby generating negative pressure. At the same time, the semi-sealed structure can effectively concentrate the suction force of the fan in the rolling sweep assembly, increasing the path resistance of air entering the rolling sweep assembly, making the suction force not easily dispersed.

[0062] Preferably, the second baffle may be connected in a magnetic manner or by a quick-release buckle to facilitate maintenance and replacement.

[0063] Preferably, a sensor and a control system can be added to the second baffle to monitor and adjust the opening and closing status and negative pressure level of the baffle in real time, and automatically adjust the baffle according to the amount of garbage and cleaning needs to achieve the best cleaning effect.

[0064] Optionally, the second baffle plate 23 is shorter than the first baffle plate 22 , the second baffle plate 23 is lower than the rolling sweep assembly 2 , and the second baffle plate 23 is wider than the rolling sweep assembly 2 .

[0065] In this embodiment, the length of the second baffle is designed to be shorter and smaller than the first baffle in order to avoid interfering with the rotation of the first baffle, and the height of the second baffle is lower than the sweeping assembly in order to ensure that the sweeping assembly can work normally; and the width of the second baffle is greater than the sweeping assembly in order to ensure the effective operation of the sweeping assembly in a negative pressure environment.

[0066] Optionally, a fixing member 24 is further provided on the support shaft 21 , and the first baffle 22 is connected to the support shaft 21 via the fixing member 24 .

[0067] In this embodiment, the fixing member 24 is a pressing piece assembly.

[0068] Specifically, the tablet pressing assembly includes:

[0069] The pressing sheet is made of high-strength metal material (stainless steel or aluminum alloy) to ensure that it has sufficient strength and durability during operation. In this embodiment, each first baffle is equipped with two pressing sheets, wherein the first pressing sheet is connected to the support shaft, and the second pressing sheet is arranged on the other side of the first baffle, opposite to the position of the first pressing sheet. The pressing sheet is provided with a fixing hole, and the pressing sheet can be installed on the support shaft 21. During installation, the first pressing sheet is connected to the second pressing sheet by bolts or rivets to ensure that it is firmly fixed;

[0070] In this embodiment, since the pressing plate is made of high-strength metal material, it can withstand greater forces during operation, thereby ensuring the strength and durability of the fixing parts and is suitable for use in various harsh working environments. A symmetrical structure is formed by the cooperation of two pressing plates (the first pressing plate is connected to the support shaft, and the second pressing plate is arranged on the other side of the first baffle plate), thereby ensuring a firm connection between the first baffle plate and the support shaft, preventing loosening, and ensuring the stability of operation.

[0071] At the same time, the design of the pressing piece can evenly distribute the force, thereby reducing local stress concentration, avoiding material fatigue or fracture caused by stress concentration, and extending the service life of the fixing.

[0072] Furthermore, the pressing plate is provided with fixing holes, which are installed by bolts or rivets. The operation is simple and quick, and it is convenient for daily maintenance and replacement. This design can quickly replace damaged or worn parts when necessary, reduce equipment downtime, and improve work efficiency.

[0073] Finally, the design of the pressing piece can adapt to baffles of different sizes and shapes. By adjusting the position and fixing method of the pressing piece, it can be flexibly applied to different types of mechanical structures, improving the versatility and adaptability of the equipment.

[0074] Optionally, a fourth baffle 14 is further provided on the side of the negative pressure chamber 16 close to the rolling sweep assembly 2. The fourth baffle 14 is relatively arranged on both sides of the negative pressure chamber 16. The fourth baffle 14 and the negative pressure chamber 16 form a notch 12, and the notch 12 is opposite to the first baffle 22.

[0075] In this embodiment, the fourth baffle concentrates the suction of the negative pressure chamber to the notch area, forming a stronger local negative pressure area at the notch position, so that the garbage can be quickly and effectively sucked into the suction cup, thereby improving the cleaning efficiency and effect.

[0076] Optionally, the first baffle 22 is made of rubber.

[0077] In this embodiment, the first baffle made of rubber can not only reduce the risk of damage to the rolling sweep assembly when encountering hard objects or large objects, but also adapt to various complex road conditions through its shock-absorbing and buffering performance, improve wear resistance and reduce maintenance costs, thereby improving the durability and work efficiency of the equipment.

[0078] Preferably, the first baffle 22 may be made of other materials besides rubber, such as polyurethane (PU), polyethylene (PE), polyvinyl chloride (PVC), nylon (PA), polypropylene (PP), thermoplastic elastomer (TPE), etc.

[0079] Optionally, a bearing 211 is further provided on the support shaft 21 , and the support shaft 21 is rotatably connected to the connecting member 15 via the bearing 211 . A protective sleeve 212 is further provided on the bearing 211 to prevent debris from entering the bearing 211 .

[0080] In this embodiment, the use of bearings can reduce the friction of the supporting shaft during rotation, improve mechanical efficiency and stability, extend the service life of components, and enhance load-bearing capacity, while the protective sleeve can prevent debris from entering the bearing, reduce wear, reduce maintenance requirements, and provide protection in humid environments, thereby ensuring efficient and stable operation of the equipment.

[0081] Preferably, the bearing may be a sliding bearing, a magnetic bearing or an air bearing.

[0082] Optionally, the rolling sweep assembly 2 further includes a third baffle 13 , and the third baffle 13 is relatively arranged on two sides of the rolling sweep assembly 2 .

[0083] In this embodiment, the third baffle is designed to effectively gather debris in the sweep assembly, while protecting the bearing from damage by external debris.

[0084] The working principle of the utility model is roughly as follows:

[0085] When working, after the fan on the upper part is started, the vehicle starts to move, the suction cup moves with the chassis vehicle, the roller of the suction cup rolls, and the fan provides negative pressure for the suction cup to suck up the garbage and sewage under the suction cup. Due to the negative pressure formed in the suction cup, the rolling sweep assembly rotates around the support shaft, and the support shaft is rotatably connected to the connecting piece through the bearing, and the bearing is fixed on the bearing sleeve and the support. The rotation of the rolling sweep assembly drives the first baffle made of rubber to rotate, and the large area of ​​leaves in front of the rubber plate are rolled into the suction cup. Under the guidance of the rolling sweep assembly, the large area of ​​leaves enter the negative pressure chamber and are finally sucked into the garbage bin.

[0086] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
