Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcium carbide crushing technology, specifically a jaw crusher base. Background Technology
[0002] In the field of calcium carbide crushing technology, jaw crushers are commonly used equipment, and their stable operation is crucial to production efficiency and product quality. Traditional jaw crusher bases are relatively simple in their fixing methods, usually relying on simple bolt connections or foundation pouring. This results in insufficient stability of the connection between the crusher and the ground. Under the long-term high-frequency vibration of the crusher, problems such as loosening and displacement can easily occur, which not only affects the normal operation of the equipment but also poses certain safety hazards.
[0003] On the other hand, traditional bases are not convenient enough for installation and maintenance. For example, positioning during installation is difficult, requiring a lot of time and effort for calibration. Furthermore, when equipment malfunctions and requires repair or replacement of parts, the unreasonable design of the base restricts operating space, making repairs difficult and time-consuming, increasing production costs and downtime, and reducing production efficiency. Therefore, developing a jaw crusher base with higher robustness and ease of use is of significant practical importance. Utility Model Content
[0004] The purpose of this utility model is to provide a jaw crusher base to solve the problems of unstable installation and inconvenient maintenance mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a jaw crusher base, comprising a hollow rectangular base, with an opening at the upper end and one side, and further comprising a U-shaped mounting plate on the base, a baffle on one side of the base opening, and a feeding plate inclined inside the base; grouting holes are provided on the bottom vertical wall of the base, and symmetrically distributed through holes are provided on both sides of the mounting plate, and nuts coaxial with the through holes are provided at the bottom of the mounting plate.
[0006] Furthermore, the base has reinforcing plates and reinforcing ribs on its vertical walls.
[0007] Furthermore, symmetrically distributed leveling plates are provided on both sides of the mounting plate.
[0008] Furthermore, hooks are provided on the inner wall of the base.
[0009] Furthermore, sleepers are provided on both sides of the mounting plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. Improved durability
[0012] Multiple reinforcement structures: The vertical walls of the base of this utility model are equipped with reinforcing plates and ribs to enhance the structural strength of the base itself, enabling it to withstand greater external impacts and equipment vibrations. When fixed to the ground, multiple grouting holes are opened on the bottom vertical wall of the base. These holes are welded to the reinforcing bars in the foundation pit, and then filled with building anchoring material and high-strength non-shrink grout, ensuring a tight bond between the base and the ground. This greatly improves the overall stability and firmness, effectively preventing problems such as base loosening and displacement caused by equipment vibrations.
[0013] Buffer and shock absorption design: The inclined feeding plate not only guides the calcium carbide feeding but also cushions the falling calcium carbide. At the same time, the sandstone filled in the backfill area absorbs impact energy, further improving the load-bearing capacity of the device, reducing the impact force on the base during operation, thereby extending the service life of the base and the equipment, and ensuring long-term stable operation of the equipment.
[0014] 2. Enhanced convenience
[0015] Easy installation: The symmetrically distributed leveling plates on both sides of the mounting plate have positioning holes, facilitating quick and accurate positioning and calibration of the equipment during installation, reducing installation time and labor costs. Furthermore, the through holes on the U-shaped mounting plate and the corresponding nuts at the bottom, combined with double-ended bolts, make the installation of the jaw crusher simple and quick, enabling rapid completion of the equipment installation and fixing work.
[0016] Easy maintenance: When the double-ended bolts used for fixing the device and jaw crusher are deformed or damaged, the new double-ended bolts can be replaced simply by unscrewing the nuts. There is no need for large-scale disassembly and adjustment of the entire base, which reduces maintenance difficulty and time costs, improves equipment maintenance efficiency, reduces downtime caused by equipment repair, and ensures production continuity.

[0023] Please see Figures 1 to 4 A jaw crusher base is used to fix a jaw crusher used for crushing calcium carbide. It mainly consists of a base 1, a mounting plate 2, a baffle 3, a discharge plate 4, and sleepers 11. All of the above components are made of steel.
[0024] Specifically,
[0025] The base 1 is rectangular in shape and hollow, forming a cavity; its upper end and one side are open structures. Multiple grouting holes 5 are symmetrically distributed on both sides of the bottom vertical wall of the base 1. A connecting plate extending outward from the bottom of each grouting hole 5 is provided. Multiple reinforcing plates 7 and reinforcing ribs 8 are also provided on the vertical wall of the base 1. Four hooks 10 are symmetrically distributed on the inner wall of the base 1.
[0026] Mounting plate 2 is U-shaped and welded to the upper end of base 1. Eight through holes are symmetrically distributed on both sides of mounting plate 2. Nuts 6 are welded to the bottom of mounting plate 2, corresponding to and coaxial with the through holes. Four horizontally welded leveling plates 9 are also symmetrically distributed on both sides of mounting plate 2, and each leveling plate 9 has positioning holes.
[0027] The baffle 3 is vertically welded to one side of the opening of the base 1, and its bottom is fixed to the bottom of the base 1 by welding with a steel plate.
[0028] The feeding plate 4 is inclined and welded to the cavity formed inside the base 1, dividing the hollow cavity into a feeding area and a backfilling area.
[0029] There are two sleepers 11, located on the upper two sides of the mounting plate 2 respectively, and slots corresponding to the through holes are opened on the sleepers 11.
[0030] Working process and principle of this utility model:
[0031] In use, the device is first excavated in the ground, creating a pit similar in size to but larger than the base 1. Reinforcing bars are then fixed to the vertical and bottom walls of the pit, their distribution corresponding to the reinforcing ribs 8. The device is then placed inside the pit, and the reinforcing bars on the bottom wall are welded to the connecting plates extending from the grouting holes 5, with the reinforcing ribs 8 interspersed with the reinforcing bars. Next, building anchoring material is poured in from above, flowing into the bottom of the pit through multiple grouting holes 5, thus fixing the bottom of the base 1. After solidification, high-strength, non-shrink grout is poured in from all sides, thus fixing the device to the ground.
[0032] Then, sandstone is filled into the backfill area divided by the feed plate 4. Double-ended bolts are then screwed into the nuts 6, and sleepers 11 are placed on both sides of the mounting plate 2. The pre-drilled mounting holes on the jaw crusher base are then aligned with the double-ended bolts and inserted. Finally, the device is secured to the jaw crusher by screwing nuts 6 into the double-ended bolts. The discharge port at the bottom of the jaw crusher is located above the discharge area divided by the feed plate 4, and a conveyor is installed on one side of the baffle 3.
[0033] If, after a period of use, the double-ended bolts used to secure the device to the jaw crusher become deformed or damaged, simply unscrew nut 6 and replace them with new double-ended bolts.
[0034] The inclined feeding plate 4 buffers the falling calcium carbide, and the backfilled sandstone can absorb the impact energy, further enhancing the load-bearing capacity of the device.
