Description

Technical Field

[0001] The present invention relates to the technical field of oil-electric loaders, and more specifically to a miniature energy-saving oil-electric hybrid four-wheel drive loader. Background Art

[0002] Loaders are earthwork machines widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. They are mainly used to shovel bulk materials such as soil, sand, lime, and coal, and can also do light shoveling of ore and hard soil. By replacing different auxiliary working devices, they can also do bulldozing, lifting, and loading and unloading of other materials such as wood.

[0003] In the prior art, the loader cab is mostly open, and the seats in the cab are mostly ordinary vehicle seats. When the driver is adapting, they can only be adjusted forward and backward in the vertical direction, and cannot adapt to the driver's body shape, which affects the driver's control feeling. It has a great impact on the driver's health when working for a long time, affects the normal loading work, and cannot meet the use needs. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a miniature energy-saving hybrid four-wheel drive loader. The technical problem to be solved by the present invention is that ordinary vehicle seats can only be adjusted forward and backward in the vertical direction and cannot adapt to the driver's body shape, which affects the driver's control experience.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a miniature energy-saving oil-electric hybrid four-wheel drive loader, comprising a body, a base is fixedly connected to the top of the body, an operating steering wheel is arranged on one side of the top of the body, a hydraulic rod is arranged on one side of the body, a bucket is connected to one end of the hydraulic rod, a frame is fixedly connected to the top of the body, a seat is fixedly connected to the top of the base, and armrests are fixedly connected to both sides of the corresponding positions of the top of the base and the seat, first fixing bolts are arranged on both sides of the seat, and the seat is threadedly connected to a connecting plate through the first fixing bolts, a first pin is arranged on the top of the connecting plate, a fixing piece is hinged to the connecting plate through the first pin, two second fixing bolts are arranged on one side of the fixing piece, and the fixing piece is threadedly connected to a chair back through the two second fixing bolts, both ends of one side of the chair back are fixedly connected to surrounding side edges, a plurality of supporting ribs are fixedly connected to the inner cavity of the surrounding side edges, and a sponge pad is fixedly connected to the side of the surrounding side edges close to the chair back;

[0006] The top of the seat is provided with a second pin, and the seat is hinged with a pad through the second pin, and the pad is fitted with the top of the seat. The seat inner cavity is provided with sliding grooves on both sides of the seat, and sliders are slidably connected in the sliding grooves on both sides. One side of the slider is provided with a connecting rod, and the top of the connecting rod is provided with a fourth pin. The bottom of the seat is fixedly connected with a threaded column, and the outer wall of the threaded column is threadedly connected to the threaded cylinder, and the outer wall of the threaded cylinder is sleeved with a first bearing, one side of the inner cavity of the seat is fixedly connected with the fixing plate, the first bearing is embedded in the top of the fixing plate, the outer wall of the threaded cylinder is sleeved with a first bevel gear, the first bevel gear is meshed with a second bevel gear, one side of the second bevel gear is fixedly connected with the rotating shaft, the outer wall of the rotating shaft is sleeved with a second bearing, the second bearing is embedded in one side of the inner cavity of the seat, and the other side of the rotating shaft is fixedly connected with a handle.

[0007] When the driver sits on the top of the pad and fits against the seat back, the surrounding side panels and the supporting ribs can be adjusted according to the fit of the driver's back, and the seat back can be adjusted by rotating the bottom connecting plate and the first pin shaft. When the driver's legs fit against the top of the pad, the handle can be turned to drive the rotating shaft to rotate in the second bearing, and the rotation of the rotating shaft drives the second bevel gear to rotate, and the rotation of the second bevel gear drives the first bevel gear and the threaded cylinder to rotate, and the threaded cylinder rotates in the first bearing to drive the threaded column connected with the thread to move upward, and the upward movement of the threaded column drives one end of the pad to move around the first bevel gear. The rotation of the second pin shaft drives one end of the pad to rise. When one end of the pad plate rises, it drives the connecting rod around the fourth pin shaft to pull the third pin shaft and the slider at the bottom to ensure the support effect of the seat back. At the same time, the bottom pad plate can provide close support to the bottom of the driver's legs, ensure the fit between the legs and the top of the vehicle body, and reduce the discomfort caused by the legs being suspended in the air for a long time. This allows the seat to be well adapted to the driver's body shape when the driver is riding, has good fit protection, reduces the impact on physical health caused by uncomfortable sitting posture during work, ensures the driver's loading work, and meets the needs of use.

[0011] In a preferred embodiment, openings are provided at positions on the top of the seat corresponding to the threaded column and the connecting rod, so as to facilitate the removal of the threaded rod and the connecting rod from the inner cavity of the seat.

[0012] In a preferred embodiment, both sides of the surrounding side edges are fixedly connected to seat belt seats, and pins are inserted in the seat belt seats, and one end of the pins on both sides is fixedly connected to the seat belt body, and a buckle is fixedly connected to one side of the seat belt body to ensure the limiting protection effect on the driver.

[0013] In a preferred embodiment, a lumbar support is fixedly connected to one side of the inner cavity of the chair back, and a headrest is fixedly connected to one side of the inner cavity of the chair back. The headrest is located on the top of the lumbar support, and both the lumbar support and the headrest are latex pads. The lumbar support on one side of the back panel can support the driver's waist, ensure the physiological curvature of the driver's waist, and effectively relieve waist fatigue.

[0014] In a preferred embodiment, the sponge pad is a memory sponge pad, and the cross-sectional shape of the sponge pad is elliptical. The sponge pad can effectively adapt to both sides of the driver's back to improve comfort.

[0015] 1. The present invention provides a surrounding side plate and a pad, and the surrounding side plate and the supporting ribs can be adjusted according to the fit of the driver's back. The seat back can be adjusted in angle by rotating the bottom connecting plate and the first pin shaft. When the driver's legs fit the top of the pad, the handle is turned to drive the rotating shaft to drive the second bevel gear, the first bevel gear and the threaded cylinder to rotate. The rotation of the threaded cylinder drives the threaded column to move and drive one end of the pad to rise. The bottom pad can fit and support the bottom of the driver's legs. Compared with the prior art, the seat can be adapted according to the driver's body shape when the driver is sitting, reducing the impact on the health of the body caused by uncomfortable sitting posture during work, ensuring the loading work of the driver, and meeting the use needs.
