Description

Technical Field

[0001] The utility model relates to the field of chains, in particular to a ditch digging machine chain which is convenient to install. Background Art

[0002] The ditch digging machine chain generally refers to a part in the crawler drive system of excavation machinery (such as excavators, ditch digging machines, etc.). It is a special chain used to transmit power and drive the crawlers of the excavation machinery to operate.

[0003] According to the Chinese authorized patent publication number: CN216275900U, a ditch digging machine chain is disclosed. Different specifications of ditch digging tooth groups can be conveniently replaced through the first installation structure, and then different specifications of trenches can be quickly adapted. After the ditch digging tooth group is worn, it only needs to be disassembled and a new ditch digging tooth group can be directly used without replacing the chain installation block, reducing the project cost. When digging ditches in soils with different hardnesses, different chain units are set. When dealing with soft soil, drill soil cup teeth that are easier to carry soil are used to improve efficiency. When mining hard soil, hard alloy ditch digging teeth that are harder and easier to crush stones are selected to improve efficiency and reduce wear. When dealing with dry or moderately hard mixed soil, drill soil cup teeth and hard alloy ditch digging teeth are used in combination for ditch digging, with more uniform force, less wear, and faster efficiency, thus adapting to different land conditions. However, there are still deficiencies in this ditch digging machine chain. The installation process of this ditch digging machine chain is relatively cumbersome. The fixation of the chain often involves multiple steps, such as adjusting the chain length and using special tools for fixation. These steps are time-consuming and prone to errors. Therefore, a ditch digging machine chain that is convenient to install needs to be designed. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides two technical solutions, specifically including the following embodiments: Embodiment 1:

[0022] A trench digging machine chain that is convenient for installation, comprising chain plates 1. The number of chain plates 1 is set to be multiple. Connecting pieces 6 are fixedly connected to the left and right sides of the lower surfaces of the multiple chain plates 1. A roller 2 is arranged between the left and right connecting pieces 6. The multiple rollers 2 are arranged alternately in sequence and are rotatably connected to each other at the alternating positions. A trench digging machine convenient installation mechanism 3 is arranged between two adjacent chain plates 1 in the middle. The trench digging machine convenient installation mechanism 3 includes a threaded cylinder 301, a threaded rod 302, a hexagonal nut 303, a rotating ring 304, an installation arm 307 and a connecting arm 308. The threaded rod 302 is threadedly connected to the middle of the threaded cylinder 301. The front and rear ends of the threaded cylinder 301 and the threaded rod 302 are respectively fixedly connected to the inner sides of two rotating rings 304. The outer sides of the two rotating rings 304 are respectively rotatably connected to the inner sides of a ferrule one 305 and a ferrule two 306. The ferrule one 305 and the ferrule two 306 are sleeved on the outer sides of the two rollers 2. A hexagonal nut 303 is sleeved on the outer side of the threaded rod 302, and the hexagonal nut 303 is fixedly connected to the threaded rod 302. To prevent the trench digging machine chain from loosening, after the threaded rod 302 retracts into the threaded cylinder 301, the installation arm 307 on the outer side of the threaded rod 302 retracts into the interior of the connecting arm 308 accordingly. Then, the fixing nut 311 on the outer side of the connecting arm 308 can be locked at the position of the bolt 310 of the installation arm 307 to prevent the chain from loosening.

[0023] During operation, during the installation of the trench digging machine chain on the driving wheel and the guiding wheel of the trench digging machine, the loose chain is sleeved on the outer sides of the driving wheel and the guiding wheel. Then, by using a hexagonal wrench to turn the hexagonal nut 303, the threaded rod 302 retracts towards the position of the threaded cylinder 301, so that the trench digging machine chain is fastened to the positions of the driving wheel and the guiding wheel. In this way, the operator can quickly adjust the tightness of the chain by rotating the hexagonal nut 303, greatly reducing the time and labor required for installation and maintenance. Embodiment Two:

[0024] On the basis of the first embodiment, connecting arms 308 are provided on both the left and right sides of the threaded cylinder 301. The two connecting arms 308 are respectively rotatably connected to the outer sides of the left and right connecting pieces 6 on the front side. Mounting arms 307 are provided on both the left and right sides of the threaded rod 302. The two mounting arms 307 are respectively rotatably connected to the outer sides of the two connecting pieces 6 on the rear side. Connecting holes 309 are formed inside both the mounting arms 307 and the connecting arms 308. A fixing nut 311 is provided outside the connecting hole 309 of the mounting arm 307. A bolt 310 is threadedly connected to the middle of the connecting hole 309 of the connecting arm 308. Gripping floor plates 4 are fixedly connected to the outer sides of multiple chain plates 1. The gripping floor plates 4 and the chain plates 1 are inclined. A guide hole cone 5 is fixedly connected to the outer side of the gripping floor plate 4. The guide hole cone 5 is made of steel. After the ditch digging machine chain is installed on the driving wheel and the guiding wheel of the ditch digging machine, during the normal travel of the ditch digging machine, the design of the guide hole cone 5 enables the ditch digging machine chain to cut deeper into the soil during travel and excavation, thereby providing greater grip and reducing the slipping phenomenon during excavation, thus improving the excavation efficiency and operation speed of the ditch digging machine.

[0025] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the application shall be included within the protection scope of the present application.
