Description

Technical Field

[0001] The utility model specifically relates to a loading and excavating integrated machine. Background Art

[0002] At present, most of the existing construction machinery has a single function. However, in many construction sites, loaders and excavators are required to work simultaneously. In the case of limited site space, the entry of too many construction vehicles will cause the site to be too crowded to carry out normal construction. Therefore, there is a need for a construction machinery that can simultaneously perform the functions of a loader and an excavator. At present, most of the power transmission systems of domestic loading and excavating integrated machines are equipped with four-wheel drive hydraulic and four-gear reversing transmission gearboxes. Such gearboxes have complex structures, large volumes, low transmission efficiency, and high fuel consumption. In application scenarios such as steel mills and marshalling yards, the maximum allowable operating speed of locomotives is 30 km / h, which results in the hydraulic reversing transmission always operating in low gears and low-efficiency areas, seriously wasting resources.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a loading and excavating integrated machine, including an integrally formed vehicle frame. A plurality of wheels are arranged at the bottom of the vehicle frame. An excavator device and a loader device are respectively arranged at both ends of the vehicle frame. An operation cab is arranged on the vehicle frame. The bottom of the operation cab is installed on the vehicle frame through a rotating device. The excavator device is movably connected to the operation cab. A reversing system is arranged inside the vehicle frame.

[0005] Preferably, the excavator device includes a support boom, a rotating middle boom, and a bucket. The tail of the support boom is hinged to the operation cab. One end of the rotating middle boom is hinged to one end of the support boom. The bucket is movably installed at the other end of the rotating middle boom. Removable digging teeth are installed on the bucket.

[0006] Preferably, the loader device includes a loading arm, a tipping arm, and a loading bucket. The loading arm is hinged to the vehicle frame. One end of the tipping arm is hinged to the loading arm. The loading bucket is movably installed on the tipping arm.

[0007] Preferably, an engine is arranged inside the vehicle frame. The output end of the engine is drivingly connected to two hydraulic torque converters. The two hydraulic torque converters are respectively drivingly connected to the front and rear axles through a transmission shaft.

[0008] Preferably, a cooling fan is arranged at the front end of the engine.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the integrated loading and excavating machine realizes the reversing function of the locomotive through the reversing system, with a large output reduction ratio, which can meet the needs of the integrated loading and excavating machine, high transmission efficiency, energy saving and high efficiency.
