Description

Technical Field

[0001] The utility model relates to the technical field of milling excavators, and more specifically to a deep-mixing milling head of a hydraulic milling deep-mixing ground-connected wall machine. Background Art

[0002] A milling machine is a machine that uses a hydraulic system to mill rocks, frozen soil, coal mines, concrete, etc. It can be installed on any type of hydraulic excavator and efficiently replaces common configurations such as buckets, breaker hammers, and hydraulic shears. It mainly uses high-speed rotating milling cutters to cut, crush, and dig ground materials, thereby achieving various complex construction tasks.

[0003] At present, in the process of underground ditch wall construction, it is necessary to use a milling machine to dig deep grooves on the ground. The milling head structure of the traditional milling machine is mainly composed of two counter-rotating milling disc structures, which are driven by a hydraulic motor to rotate in opposite directions to achieve deep digging. However, the milling disc structure of the traditional milling machine mainly relies on its own gravity to contact with the soil, and is driven by a hydraulic motor to achieve digging. In actual use, it is not convenient to achieve active excavation of the soil, which affects the construction efficiency. In view of this, we propose a hydraulic milling deep mixing milling head for a ground ditch wall machine. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide a hydraulic milling deep mixing ground wall machine deep mixing milling head to solve the technical problem that the current existing milling and digging structure is not convenient for active excavation of soil, affecting construction efficiency.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a hydraulic milling deep mixing ground wall machine deep mixing milling head, including a shell assembly with a milling and digging assembly arranged inside;

[0006] The housing assembly comprises a symmetrically arranged and fixedly connected milling head housing, wherein the milling head housing has symmetrically formed shaft holes;

[0007] The milling and digging assembly includes a symmetrically arranged milling and digging structure;

[0009] By symmetrically setting the milling and digging structure and designing the milling and digging cutter wheel in the milling and digging structure to be eccentrically set relative to the rotating shaft, during the process of the milling and digging cutter wheel rotating to mill and dig the soil, the eccentric setting of the milling and digging cutter wheel will intermittently exert active pressure on the soil, thereby assisting it to break into the soil faster for milling and digging, which is beneficial to improving construction efficiency.

[0010] Preferably, the milling cutter wheels in the symmetrically arranged milling and digging structures are arranged obliquely.

[0011] Preferably, a second limit block is symmetrically arranged on the outer edge surface of the rotating shaft, and one side of the second limit block abuts against the milling head housing.

[0012] Preferably, a socket is formed inside the milling head housing, the top of the socket extends toward the inside of the milling head housing to form a limiting groove, and the top of the milling head housing is formed with a through hole connected to the limiting groove.

[0013] Preferably, a receiving component is provided between the milling head housing, and the receiving component includes a screw rod detachably inserted in the socket, one end of the screw rod extends out of the socket rod and is threadedly connected with a nut, a gasket is provided between the nut and the screw rod and the milling head housing, and a fixed pulley is rotatably mounted on the outer edge surface of the screw rod.

[0014] Preferably, a limiting block 1 is detachably arranged in the limiting groove, and a bolt is installed in cooperation with the internal thread of the limiting block 1. The bolt is arranged in the through hole, and the outer edge surface of the screw rod is located on both sides of the fixed pulley and a limiting seat abutting against one side of the milling head housing can be detachably installed.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model symmetrically arranges the milling and digging structure, and designs the milling and digging cutter wheel in the milling and digging structure to be eccentrically arranged relative to the rotating shaft. In the process of the milling and digging cutter wheel rotating to perform milling and digging work on the soil, the eccentric arrangement of the milling and digging cutter wheel will intermittently exert active pressure on the soil, thereby assisting it to break into the soil faster for milling and digging work, which is beneficial to improving construction efficiency and solves the problem that the existing milling and digging structure is not convenient for realizing active excavation of the soil, thus affecting construction efficiency.

[0017] 2. The utility model also arranges arc-shaped gear teeth in a ring array structure on the outer edge surface of the milling cutter wheel. The arc structure of the arc-shaped gear teeth combined with the eccentric setting of the milling cutter wheel is conducive to further improving the active milling effect of the soil, thereby further improving the construction efficiency.

[0018] 3. The utility model also tilts the milling cutter wheel in the milling structure, which is beneficial to increase the milling width in the axial direction compared to the parallel setting, thereby indirectly improving the milling efficiency. At the same time, the tilted setting of the milling cutter wheel is beneficial to forming a certain angle when in contact with the soil, thereby exerting a thrust on the soil in the axial direction, which can further improve the active milling effect on the soil.
