Description

Jaw crusher base Technical Field The utility model relates to the technical field of calcium carbide crushing, in particular to a jaw crusher base. Background In the technical field of calcium carbide crushing, jaw crushers are common equipment, and stable operation of the jaw crushers is crucial to production efficiency and product quality. Traditional jaw breaker base is comparatively single in fixed mode, generally only relies on simple bolted connection or basis to pour, leads to its firm in connection with ground not enough, and under the long-term high frequency vibrations operating condition of breaker, the problem such as becoming flexible, displacement appear easily, not only influence the normal operating of equipment, still have certain potential safety hazard. On the other hand, the conventional base is not convenient enough in the installation and maintenance process. For example, positioning is difficult during installation, a great deal of time and effort are required for calibration, and when equipment fails and maintenance or replacement of components are required, due to unreasonable base structural design and limited operation space, maintenance work is difficult and time-consuming, production cost and downtime of enterprises are increased, and production efficiency is reduced. Therefore, it is important to develop a jaw crusher base with higher firmness and convenience. Disclosure of utility model The utility model aims to provide a jaw crusher base which is used for solving the problems that the installation is not stable enough and the maintenance is not convenient enough in the background art. The jaw crusher base comprises a hollow rectangular base, wherein the upper end and one side of the base are provided with openings, the jaw crusher base further comprises a U-shaped mounting plate arranged on the base, a baffle plate arranged on one side of the opening of the base, and a blanking plate obliquely arranged in the base, grouting holes are formed in the vertical wall of the bottom of the base, symmetrically distributed through holes are formed in two sides of the mounting plate, and nuts coaxial with the through holes are arranged at the bottom of the mounting plate. Further, the vertical wall of the base is provided with a reinforcing plate and reinforcing ribs. Further, symmetrically distributed leveling plates are arranged on two sides of the mounting plate. Further, a hook is arranged on the inner wall of the base. Further, sleepers are arranged on two sides of the mounting plate. Compared with the prior art, the utility model has the following beneficial effects: 1. fastness improvement The utility model relates to a multiple reinforcing structure, wherein a reinforcing plate and reinforcing ribs are arranged on the vertical wall of a base, so that the structural strength of the base is enhanced, and the base can bear larger external force impact and equipment vibration. When fixed with ground, a plurality of grout holes are offered to the base bottom perpendicular wall, through with the interior reinforcing bar welded fastening of foundation ditch, pour into again and build muscle anchor material and high-strength non-shrink grouting material into, make base and ground close combination, greatly improve holistic stability and fastness, effectively avoid the base that leads to because of equipment vibrations not hard up, the displacement scheduling problem. The buffer and shock absorption design is that the obliquely arranged blanking plate not only plays a role in guiding the calcium carbide blanking, but also can buffer the fallen calcium carbide. Meanwhile, the sandstone filled in the backfill area can absorb impact energy, so that the bearing capacity of the device is further improved, the impact force of equipment on the base during working is reduced, the service lives of the base and the equipment are prolonged, and long-term stable operation of the equipment is ensured. 2. Convenience enhancement The installation is convenient, locating holes are formed in the leveling plates symmetrically distributed on two sides of the installation plate, so that the equipment can be conveniently and rapidly positioned and calibrated in the installation process, and the installation time and labor cost are reduced. In addition, through-hole and the corresponding nut design in bottom on the U-shaped mounting panel cooperate the stud for jaw breaker's installation operation is simple swift, can accomplish the installation fixed work of equipment fast. The novel threaded bolt is convenient to maintain, when the threaded bolt used for the fixing device and the jaw crusher is deformed or damaged, the novel threaded bolt can be replaced by unscrewing the nut, the whole base is not required to be detached and adjusted on a large scale, the maintenance difficulty and the time cost are reduced, the maintenance efficiency of equipment is improved, the downtime caused by equipment maintenance i
