Description

Technical Field

[0001] This utility model relates to the field of skid steer loader technology, and more specifically to a small, ride-on, side-operated skid steer loader. Background Technology

[0002] Skid steer loaders, also known as skid steer loaders, multi-purpose engineering vehicles, or multi-purpose engineering machines, are wheeled specialized chassis equipment that achieves steering by utilizing the difference in linear speed between the wheels on both sides. They are mainly used in situations where the work area is confined, the ground is uneven, and the work content changes frequently. The biggest feature of skid steer loaders is their small overall size and ability to turn on the spot; they can quickly change or attach various working devices on the job site. There are two types of skid steer loaders: those with a cab and those without. In skid steer loaders with a cab, the cab is located in the center of the machine, ensuring stability and maximizing operator safety. Skid steer loaders without a cab have a footrest at the rear for the driver to stand on. These structural improvements are all made to ensure a small size and a stable center of gravity.

[0024] The first embodiment of this utility model is as follows:

[0025] A small, ride-on, side-operated skid steer loader includes a chassis 1. A support base 10 is located at the front of the chassis 1, and the support base 10 is hinged to a bucket assembly. The front of the support base 10 has an inclined surface and a groove for accommodating the bucket assembly. The bucket assembly includes a boom 9, which has an X-shaped structure. The upper end of the boom 9 is hinged to the upper end of the support base 10, providing a more stable two-point connection. The lower end of the boom 9 is hinged to a bucket 7. An angle-adjusting cylinder 8 is hinged inside the boom 9, and the other end of the angle-adjusting cylinder 8 is connected to the bucket. 7. The hinge point between the angle-adjusting cylinder 8 and the bucket 7 is located below the hinge point between the boom 9 and the bucket 7. The angle of the bucket 7 is controlled by extending and shortening the angle-adjusting cylinder 8. The bucket assembly also includes a lifting cylinder 11. The lower end of the lifting cylinder 11 is hinged to the lower part of the upper frame 1, and the upper end of the lifting cylinder 11 is hinged to the middle part of the boom 9. The hinge point between the lifting cylinder 11 and the boom 9 is located below the hinge point between the boom 9 and the support seat 10. The relative angle between the boom 9 and the support seat 10 is controlled by extending and shortening the lifting cylinder 11, thereby adjusting the height of the bucket 7.

[0026] The upper frame 1 is equipped with an engine, which is connected to a double gear pump via a coupling to generate high pressure hydraulic oil. This high pressure oil is delivered to various hydraulic valves through hydraulic pipelines. The pipeline includes a multi-way valve. By inputting commands through the handle 14, the flow direction, pressure and flow rate of the hydraulic oil in the multi-way valve are precisely controlled, thereby controlling the extension and retraction of the angle adjustment cylinder 8 and the lifting cylinder 11.

[0027] The seat adopts a ride-on design, making work more comfortable and reducing fatigue during long hours of work. The seat 13 includes a seat cushion and a backrest hinged to the rear of the seat cushion. The overall design of the seat 13 is a flip-up type, which makes assembly more convenient. The operating handles 14 are located on both sides of the seat 13. The layout of operating on both sides allows the operator to accurately control various work actions, which can greatly improve work efficiency.

[0028] The upper part of the upper frame 1 is also provided with a canopy 12, which is located directly above the seat 13. It can shield the driver from wind and rain and improve driving comfort.
