Description

Technical Field

[0001] This utility model relates to the field of engineering machinery and equipment technology, and in particular to a loader bucket vibration cleaning system. Background Technology

[0002] A loader is a type of earthmoving machinery widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. It is mainly used for loading and unloading bulk materials such as soil, sand, gravel, lime, and coal. It can also perform light digging operations on ores and hard soil. When unloading materials with strong viscosity by turning over the bucket, the material tends to stick to the bucket.

[0003] In existing technologies, a common method is to rapidly tilt the bucket, causing the rear limit block of the bucket to impact the boom longitudinal beam, generating a strong impact force to dislodge adhering materials. Specifically, during unloading, the bucket cylinder is operated to rapidly extend and retract the bucket, repeating this 2-3 times to tilt the bucket, causing the rear limit block to impact the boom longitudinal beam and generate high-frequency vibration, thus dislodging the adhering materials. However, this method still has the following drawbacks:

[0004] 1. The vibration frequency generated by manual operation is very limited, resulting in low cleaning efficiency, and some sticky materials are still difficult to remove;

[0005] 2. The impact force generated by the tipping bucket can easily lead to fatigue damage to components, affecting their normal service life. Utility Model Content

[0006] This application provides a loader bucket vibration cleaning system, which can generate high-frequency vibration through a vibrator to achieve rapid material stripping, high cleaning efficiency, and is less likely to cause fatigue damage to components.

[0007] This application provides a loader bucket vibration cleaning system, including a compressed gas source, a first air storage tank, a controller, and a pneumatic vibrator. The compressed gas source is an external air compressor or an air compressor built into the loader, used to supply air to the first air storage tank. The compressed gas source is connected to the pneumatic vibrator via a solenoid valve. The solenoid valve and the first air storage tank are both controllably connected to the controller so that when the pressure in the first air storage tank is greater than a first threshold, the controller opens the solenoid valve to input gas into the pneumatic vibrator. The pneumatic vibrator is installed on the back of the loader bucket or symmetrically distributed on the left and right sides of the loader bucket.

[0008] In one possible implementation, the compressed gas source is an air compressor built into the loader. The loader bucket vibration cleaning system further includes a second air tank and a reversing valve. The second air tank is connected to the loader's foot brake as a service brake. The reversing valve is a two-position five-way reversing valve with a P port, an A port, and a B port. The reversing valve is connected to an oil-water separator valve through the P port, connected to the second air tank through the A port, and connected to the first air tank through the B port. The compressed gas source supplies air to both the first and second air tanks simultaneously through the reversing valve. A first pressure sensor is installed in the first air tank, and a second pressure sensor is installed in the second air tank. Both the first and second pressure sensors are signal-connected to the controller.

[0009] In one possible implementation, the controller is integrated with a display screen to show the pressure values ​​inside the first and second air storage cylinders.

[0010] In one possible implementation, the loader bucket vibration cleaning system further includes a pressure reducing valve, and the compressed gas source is connected to the pneumatic vibrator in sequence through the pressure reducing valve and the solenoid valve.

[0011] In one possible implementation, the pressure reducing valve is a manually rotary adjustable pressure regulating valve.

[0012] Beneficial effects: Compared with the prior art, the loader bucket vibration cleaning system provided in this application sets pneumatic vibrators on the back or left and right sides of the loader bucket. During unloading, the pneumatic vibrators transmit vibration to the bucket, which can quickly peel off the material adhering to the bucket. The cleaning efficiency is high, and at the same time, it can avoid the fatigue damage of the parts caused by violent bucket overturning, and can ensure the normal service life of the relevant parts.

[0013] By using the loader's own air compressor, and coordinating it with the second air tank and reversing valve to work together between the vehicle braking and the pneumatic vibrator vibration, equipment costs can be saved, the overall structure can be made more compact, and the space occupied by the equipment can be reduced.

[0014] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0019] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0020] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0021] refer to Figures 1 to 3 This application provides a loader bucket vibration cleaning system, including a compressed gas source, a first air tank, a controller, and a pneumatic vibrator. The compressed gas source is an external air compressor or an air compressor built into the loader, used to supply air to the first air tank. The compressed gas source is connected to the pneumatic vibrator via a solenoid valve. Both the solenoid valve and the first air tank are controllably connected to the controller. When the pressure in the first air tank exceeds a first threshold, the controller opens the solenoid valve, thereby inputting gas to the pneumatic vibrator. The pneumatic vibrator is installed on the back of the loader bucket or symmetrically distributed on the left and right sides of the loader bucket to transmit vibration to the entire inner wall of the bucket, thereby peeling off adhering materials. Therefore, the loader bucket vibration cleaning system provided by this application can quickly peel off materials adhering to the bucket, achieving high cleaning efficiency. It also avoids fatigue damage to components caused by violent bucket overturning, ensuring the normal service life of related parts.

[0022] In one embodiment, the compressed gas source is an air compressor built into the loader. The loader bucket vibration cleaning system also includes a second air tank and a reversing valve. The second air tank serves as a service brake and is connected to the loader's foot brake. The reversing valve is a two-position five-way reversing valve with a P port, an A port, and a B port. The reversing valve is connected to an oil-water separator valve through the P port, to the second air tank through the A port, and to the first air tank through the B port. The compressed gas source supplies air to both the first and second air tanks simultaneously through the reversing valve. In addition, a first pressure sensor is installed in the first air tank, and a second pressure sensor is installed in the second air tank. Both the first and second pressure sensors are signal-connected to the controller.

[0023] The work process is roughly as follows:

[0024] The brake air reservoir, also known as the second air reservoir, has the highest priority for inflation. After the controller is turned on, it first checks the air pressure of the second air reservoir. If the air pressure in the second air reservoir is too low, because the working air pressure for the service brake cannot be less than 0.4MPa, the controller is set to activate the reversing valve when the pressure is less than 0.5MPa, prioritizing inflation of the second air reservoir to the safety threshold of 0.8MPa for service braking. Then, it checks the air pressure of the first air reservoir. If the vibration air pressure is ≤0.6MPa, the controller needs to activate the reversing valve to inflate the first air reservoir. If the first air reservoir does not need inflation, the air compressor will continuously supply air to the second air reservoir used for air-assisted braking, which is the default setting.

[0025] After the pneumatic vibrator is turned on, if the pressure in the first air tank exceeds 0.6 MPa, the controller opens the solenoid valve. Gas from the first air tank, after being depressurized by the pressure reducing valve, enters the pneumatic vibrator through the inlet, causing it to vibrate. The vibration is transmitted to the entire inner wall of the bucket, quickly peeling away adhering material. The vibration frequency is determined by the pressure set by the pressure reducing valve. If the pressure in the first air tank is insufficient to reach 0.6 MPa, the first air tank is first filled to the safety valve pressure before the pneumatic vibration mode is activated. The pressure values ​​in the first and second air tanks are determined by the first and second pressure sensors, respectively.

[0026] Therefore, the loader bucket vibration cleaning system provided in this application can not only meet the loader's driving and braking needs by utilizing the loader's own air compressor, but also meet the vibration needs of the pneumatic vibrator. It can significantly save equipment costs while using high-frequency vibration to peel off adhering materials. At the same time, the overall equipment is more compact and occupies less space.

[0027] In one embodiment, the controller is integrated with a display screen to display the pressure values ​​inside the first and second air storage cylinders, allowing for intuitive viewing of the pressure values ​​inside the first and second air storage cylinders and facilitating manual operation.

[0028] In one embodiment, the loader bucket vibration cleaning system further includes a pressure reducing valve. The compressed gas source is connected to the pneumatic vibrator in sequence through the pressure reducing valve and the solenoid valve. This allows the pressure required by the pneumatic vibrator to be adjusted according to the viscosity of the material. For example, when the viscosity is high, a higher pressure is provided, and the number of vibration cycles per unit time of the pneumatic vibrator will increase accordingly, resulting in a faster vibration frequency. When the viscosity of the material is low, the pressure is lowered accordingly. Thus, by driving with different pressures, high and low frequency vibrations within a certain range can be achieved. This system is suitable for both loose and sticky materials and has a wide range of applications.

[0029] More preferably, the pressure reducing valve is a manually adjustable rotary pressure regulating valve, which is convenient to be manually adjusted as needed to match the adhesive materials with different degrees of looseness.

[0030] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
