The working principle and structural characteristics of excavator ripper bucket

We all know that the excavator ripper bucket is easy to use in the destruction project. It can help us save a lot of time and greatly improve our efficiency. However, according to our understanding, many excavator masters are not very clear on how to use the excavator ripper bucket. We can’t just use the excavator ripper bucket just because it is hard. No matter how hard it is, it will be damaged if it is consumed for a long time. Today we take a look at the working principle and structural characteristics of scarifiers, hoping to help those who do not know how to use them correctly.

The working principle of excavator ripper bucket:

The excavator ripper bucket is connected with the main boom cylinder and the main boom, one end of the main boom is connected with the forearm fulcrum, the forearm is connected with the forearm cylinder and the ripper, and the ripper is connected with the ripper. It is characterized by: the forearm cylinder The ratio of the distance from the rod head support point to the forearm fulcrum to the distance from the forearm fulcrum to the ripper is 0.4-0.8. By shortening the arm length and increasing the thickness of the arm, the weight of the main arm and the forearm is increased, and the hydraulic cylinder is increased. Capacity, thereby generating greater power. Change the ratio of the upper and lower sections of the forearm fulcrum to move the rod head fulcrum of the forearm cylinder upwards, so that the length between the forearm fulcrum and the thrust point of the forearm cylinder accounts for the ratio of the entire forearm length, thereby increasing the excavation power.

The structural characteristics of the excavator ripper bucket:

1. The excavator ripper bucket is used to connect the connecting plate with the lifting equipment. The connecting plate can connect the tamping machine with the lifting equipment for use on the excavator or other lifting equipment. The wear-resistant blade, which is fixed at the lower end of the connecting plate, is a key component used for crushing the side walls of crushed stone, sub-hard stone and weathered stone.

2. The wear-resistant teeth are detachably connected to the excavator ripper bucket and the wear-resistant blade. The wear-resistant teeth have a triangular cross section and are used to crush the bottom or middle of crushed stone, sub-hard stone, and weathered stone. There are several raised blades on the wear-resistant blade. The blade is a key component of the wear-resistant blade and plays a major role in breaking.

3. The cross section of the blade part of the excavator ripper bucket is triangular. In order to facilitate the timely discharge of the broken stone from the blade part, the transition part between two adjacent blade parts is also designed as a concave curved surface. The concave curved surface design makes the broken stone The block can fall off from the blade, enter the concave surface, and then discharge from the concave surface. In order to increase the contact area between the connecting plate and the receiving plate, and to enhance the bearing strength of the connecting plate, the following technical measures can also be adopted: an inverted trapezoidal receiving block is fixed at the lower end of the connecting plate.

4. In order to facilitate the installation of the excavator ripper bucket on the lifting equipment or excavator, the following technical measures can also be adopted: the connecting plate includes two ear plates symmetrically arranged on the upper end of the receiving block. In order to optimize the structural design of the wear-resistant blade, the wear-resistant blade adopted by the excavator ripper bucket includes a vertically arranged support part and a curved installation part designed integrally with the support part and used for connecting the wear-resistant teeth. Among them, the ripper support part can directly connect the wear-resistant blade with the connecting plate, or directly connect with the receiving block. The curved mounting part is used to connect the wear-resistant teeth and is used for the bottom of crushed stone, sub-hard stone and weathered stone. Or crush it in the middle.
