Problems solved by technology

[0002] Due to the fixed weight of the existing ordinary grab, its fuel consumption cannot be changed according to the requirements of the working conditions, which reduces the utilization rate of fuel, and the counterweight is installed inside the grab body, which will block the backflow channel of the mud
Especially when the grab body is rising and falling, the mud cannot pass through the grab body quickly, which increases the lifting and lowering resistance of the grab body, thereby reducing the lifting and lowering speed of the grab

Abstract

The invention discloses a grab bucket system and an engineering vehicle. The grab bucket system comprises a grab bucket body, a bucket head assembly and a balancing weight assembly; the bucket head assembly is mounted below the grab bucket body, the balancing weight assembly is mounted on the outer side of the grab bucket body, the balancing weight assembly comprises a balancing weight set, the balancing weight set is connected with the grab bucket body through a balancing weight position, the balancing weights in the balancing weight set are detachably connected, the balancing weights are added and decreased according to the working condition, and the weight of the grab bucket body is adjusted. According to the grab bucket system, the balancing weight assembly is arranged on the outer side of the grab bucket body, and is used for adjusting the weight of the grab bucket body, the excavating capacity of the bucket head assembly is adjusted, an anti-surging channel of slurry is not affected, lifting and descending resistance of slurry to the grab bucket body is effectively avoided, the fuel oil use rate is improved, and the fuel economy and environment-friendly high needs can be met.

Description

technical field [0001] The invention relates to the field of excavating equipment, in particular to a grab system and an engineering vehicle. Background technique [0002] Due to the fixed weight of the existing ordinary grab, its fuel consumption cannot be changed with the requirements of the working conditions, which reduces the utilization rate of the fuel, and the counterweight is installed inside the grab body, which will block the backflow channel of the mud. Especially during the ascent and descent of the grab body, the mud cannot pass through the grab body quickly, which increases the lifting and lowering resistance of the grab body, thereby reducing the lifting and lowering speed of the grab. Contents of the invention [0003] The object of the present invention is to provide a grab system to adjust the weight of the grab body through the counterweight assembly arranged outside the grab body, thereby adjusting the digging capacity of the bucket head assembly.
