Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a skid steer loader with a baffle cleaning device. Background Technology

[0002] Skid steer loaders are indispensable multi-functional small machines in engineering construction, and their core working component is the front bucket. When performing material handling tasks, especially after handling sticky materials such as wet soil, concrete mortar, or industrial waste, a large amount of residue will inevitably adhere to the inner surface of the bucket and the upper baffle.

[0003] These residues directly reduce the effective volume of the bucket, increase the vehicle's ineffective weight, thereby reducing the efficiency of each load and increasing fuel consumption in subsequent operations. More importantly, if not cleaned in time, the residues become extremely difficult to remove once they dry and harden, and can also cause cross-contamination when loading different types of materials, affecting the quality of the project.

[0004] Currently, cleaning of the bucket and baffles generally relies on manual methods. Operators need to manually clean them using tools such as shovels and high-pressure water guns during work breaks. This method is not only labor-intensive and creates a poor working environment, but it is also time-consuming and labor-intensive, directly leading to equipment downtime and seriously affecting the overall efficiency of continuous operation. In addition, the results of manual cleaning are often unsatisfactory, especially for areas such as the corners of the bucket, which are difficult to clean thoroughly.

[0005] Therefore, this utility model proposes a skid steer loader with a baffle cleaning device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a skid steer loader with a baffle cleaning device, which aims to improve the problems of difficulty in cleaning the bucket and baffle attachments, reliance on manual labor, low cleaning efficiency and lack of effective shock absorption protection for drivers and passengers in the existing skid steer loader.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a skid steer loader with a baffle cleaning device, comprising: a body, a lifting arm mounted on the body, a bucket connected to the lifting arm, and a cab mounted on the body; and a cleaning device mounted on the body.

[0008] The cleaning device includes a rotating shaft rotatably mounted on the machine body, a slider slidably connected to the rotating shaft, a brush roller, and an electric push rod.

[0009] One end of the electric actuator is connected to the slider, and the other end is connected to the brush roller. The brush roller is driven to extend or retract relative to the slider, so that the brush roller can contact or detach from the bucket to perform cleaning operations after the shaft rotates.

[0010] Furthermore, the cleaning device also includes a water tank, a water pipe, and a rotary joint; the brush roller has a hollow structure and its roller surface is provided with several water outlet holes; one end of the rotary joint is connected to the water pipe, and the other end is connected to the hollow cavity of the brush roller.

[0011] Furthermore, a stop is fixedly provided on at least one end of the rotating shaft to limit the sliding range of the slider on the rotating shaft.

[0012] Furthermore, the skid steer loader also includes a baffle disposed above and behind the bucket.

[0013] Furthermore, the skid steer loader also includes a shock-absorbing assembly disposed between the fuselage and the cab.

[0014] Furthermore, as a specific implementation, the shock absorption assembly includes an air spring, a push rod, a hydraulic base, an oil circuit, and a hydraulic oil tank.

[0015] Furthermore, the push rod is vertically fixed to the bottom of the cockpit; the hydraulic seat is sleeved on the outside of the push rod and connected to the fuselage; the hydraulic seat contains hydraulic oil and is connected to the hydraulic oil tank through an oil circuit; the air spring is disposed between the cockpit and the hydraulic seat.

[0016] Furthermore, the skid steer loader also includes a storage box mounted on the machine body, the hydraulic oil tank being detachably mounted inside the storage box, and the storage box being equipped with a cover for opening and closing.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, a cleaning device consisting of a rotating shaft, a slider, an electric push rod, and a brush roller is integrated into the machine body. This device can realize multi-degree-of-freedom movement such as rotation, sliding, and extension. In conjunction with a water spraying system, it solves the problems of existing loaders' buckets and baffles being difficult to clean after dirt adheres, relying on manual labor, and being inefficient. It achieves the technical effect of automatic, fast, and efficient self-cleaning of the buckets and baffles, and significantly reduces labor intensity.

[0019] 2. In this utility model, by setting a set of hydraulic damping mechanism consisting of hydraulic seat and top rod and shock absorption component with air spring working together between the machine body and the cab, the problem of severe cab vibration and poor driving comfort of existing loaders when driving on uneven roads is solved. It achieves the technical effect of effectively dissipating and absorbing impact kinetic energy, thereby significantly reducing cab vibration and improving operating comfort and driving safety.

[0020] 3. In this utility model, by combining a slider that can slide on the rotating shaft with an electric push rod that drives the brush roller to extend and retract, and installing them as a whole on the rotatable rotating shaft, the brush roller has the ability to adjust laterally, longitudinally, and at an angle. This solves the problem that a single cleaning action cannot cover the irregular curved surface of the inner wall of the bucket, and achieves the technical effect of cleaning the bucket and baffle in all directions without dead angles, ensuring thorough cleaning.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a skid steer loader with a baffle cleaning device, which aims to solve the problems of existing loaders lacking an integrated cleaning mechanism, resulting in difficulties in cleaning the bucket and baffle, and poor shock absorption effect in the connection between the cab and the body.

[0029] like Figure 1 As shown, the skid steer loader with baffle cleaning device includes a body 1, a lifting arm 2 mounted on the body 1, a bucket 11 connected to the lifting arm 2, and a cab 13 mounted on the body 1. The body 1 serves as the mounting platform for all components of the machine. The skid steer loader also includes a cleaning device mounted on the body 1. The core structure of the cleaning device includes a rotating shaft 3 rotatably mounted on the body 1, a slider 5 slidably connected to the rotating shaft 3, a brush roller 7, and an electric push rod 6. Specifically, one end of the electric push rod 6 is connected to the slider 5, and the other end is connected to the brush roller 7. Through the extension and retraction of the electric push rod 6, the brush roller 7 is driven to extend or retract relative to the slider 5. Thus, after the rotating shaft 3 rotates to a predetermined angle, the brush roller 7 can effectively contact or disengage from the bucket 11 and the baffle 12 located above and behind the bucket 11, thereby achieving the cleaning operation.

[0030] To ensure the stability and safety of the cleaning device, a stop block 4 is fixedly provided on at least one end of the rotating shaft 3. The stop block 4 is used to physically limit the sliding range of the slider 5 along the rotating shaft 3 and prevent the slider 5 from falling off the rotating shaft 3 due to abnormal operation or vibration.

[0031] To achieve the combined cleaning function of brushing and rinsing, the cleaning device also includes a liquid supply system, which includes a water tank 10, a water pipe 9, and a rotary joint 8. The brush roller 7 itself has a hollow structure, and its roller surface has several water outlet holes. The water tank 10 is used to store cleaning liquid and is connected to one end of the rotary joint 8 through the water pipe 9. The other end of the rotary joint 8 is connected to the hollow cavity of the brush roller 7. When rinsing is required, the liquid in the water tank 10 is injected into the rotating brush roller 7 through the water pipe 9 and the rotary joint 8 and sprayed out from the water outlet holes. The setting of the rotary joint 8 ensures that the liquid supply pipeline will not entangle or twist while the brush roller 7 is rotating at high speed, thus realizing continuous water supply rinsing.

[0032] To further improve the smoothness of the machine's ride and the comfort of operation, the skid steer loader with baffle sweeping device also includes a shock absorption assembly 14 located between the chassis 1 and the cab 13;

[0033] Specifically, the shock absorption assembly 14 includes an air spring 141, a push rod 142, a hydraulic seat 143, an oil passage 144, and a hydraulic oil tank 145. In terms of installation structure, the push rod 142 is vertically fixed to the bottom of the cockpit 13, the hydraulic seat 143 is sleeved on the outside of the push rod 142 and connected to the fuselage 1, the hydraulic seat 143 contains hydraulic oil and is connected to the hydraulic oil tank 145 through the oil passage 144; the air spring 141 is disposed between the cockpit 13 and the hydraulic seat 143, and works in parallel with the hydraulic damping structure composed of the push rod 142 and the hydraulic seat 143; when the fuselage 1 is bumped due to uneven road surface, the hydraulic seat 143 moves up and down, compressing the hydraulic oil inside, forcing the hydraulic oil to flow into the hydraulic oil tank 145 through the oil passage 144. In this process, the impact kinetic energy is converted into heat energy, while the air spring 141 absorbs the remaining vibration energy, thereby jointly achieving effective shock absorption of the cockpit 13.

[0034] To facilitate the maintenance of the shock absorption assembly 14, the skid steer loader also includes a storage box 15 installed on the body 1. The hydraulic oil tank 145 is detachably installed in the storage box 15. The storage box 15 is also equipped with a cover 16 for opening and closing. Opening the cover 16 allows for convenient inspection or replacement of the hydraulic oil tank 145.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred embodiment, in order to achieve flushing and cleaning of the bucket 11 and the baffle 12, the brush roller 7 of the cleaning device preferably adopts a hollow structure, and its roller surface is evenly distributed with a number of water outlet holes along the circumferential and axial directions; the water tank 10 is connected to one end of the rotary joint 8 through the water pipe 9, and the other end of the rotary joint 8 is connected to the hollow cavity of the brush roller 7 to form a complete liquid conveying channel.

[0037] In a preferred embodiment, to improve the safety of the slider 5 during the sliding process and prevent it from detaching from the rotating shaft 3, a stop 4 is fixedly provided at at least one end of the rotating shaft 3. The stop 4 limits the maximum sliding stroke of the slider 5.

[0038] In a preferred embodiment, the skid steer loader is further fixedly connected to a baffle 12 above and behind the bucket 11, and the baffle 12 and the bucket 11 together form the working surface to be cleaned;

[0039] As a preferred embodiment, in order to achieve composite shock absorption of the cockpit 13, the internal structure of the shock absorption assembly 14 is specifically configured as follows: the top end of the top rod 142 is vertically fixed to the bottom of the cockpit 13, the inner hole of the hydraulic seat 143 is sleeved on the outside of the top rod 142, and the bottom of the hydraulic seat 143 is connected to the fuselage 1, while the air spring 141 surrounds the outside of the top rod 142 and is supported between the bottom of the cockpit 13 and the top of the hydraulic seat 143.

[0040] As a preferred embodiment, in order to facilitate the maintenance and replenishment of the hydraulic system, a storage box 15 is also fixedly provided on the machine body 1. The hydraulic oil tank 145 is detachably housed in the storage box 15, and a box cover 16 is installed on the top of the storage box 15 by means of hinge.

[0041] Working principle: During cleaning operations, the operator in the cab 13 first controls the lifting arm 2 to adjust the bucket 11 to the position to be cleaned, and then controls the rotating shaft 3 to rotate the brush roller 7 and electric push rod 6 to the work area; then controls the electric push rod 6 to extend, driving the brush roller 7 to extend and make its bristles contact the surface of the bucket 11 or baffle 12; at this time, the water supply system is started, and the cleaning liquid in the water tank 10 enters the hollow cavity of the brush roller 7 through the water pipe 9 and the rotary joint 8, and is sprayed out from several water outlets on its surface to soak and soften the stains; then, the brush roller 7 begins to rotate, and its bristles mechanically scrub the stains, while the rotary joint 8 continuously supplies water to its interior to wash away the brushed dirt while ensuring that the brush roller 7 can rotate freely; when an area is cleaned, the slider 5 slides along the rotating shaft 3 to move the brush roller 7 to the next area to be cleaned, until all cleaning operations are completed. During this process, the stop block 4 at the end of the rotating shaft 3 always limits the stroke of the slider 5 to prevent it from falling off.

[0042] When the skid steer loader travels on uneven roads and experiences bumps, the chassis 1 transmits the vibration to the damping assembly 14. The hydraulic seat 143, connected to the chassis 1, moves upward under the force. Since the top rod 142 is fixed to the bottom of the cab 13, the upward movement of the hydraulic seat 143 compresses the hydraulic oil inside and forces it to flow into the hydraulic oil tank 145 through the oil passage 144. This process converts most of the impact kinetic energy into the heat energy of the hydraulic oil. At the same time, the air spring 141, located between the cab 13 and the hydraulic seat 143, is compressed, absorbing the remaining vibration kinetic energy and converting it into its own elastic potential energy. Through the synergistic effect of hydraulic damping and air spring, the vibration transmitted to the cab 13 is greatly reduced, improving the comfort of operation.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
