Technical Field

[0001] The utility model belongs to the technical field of sand making equipment, and in particular relates to a vibration reduction base of a mine sand making machine. Background Art

[0002] Vertical impact crusher and sand maker is widely used in medium and fine crushing of various hard and brittle materials, and is particularly suitable for construction sand and road gravel. The hx type vertical impact crusher consists of seven parts: feed hopper, distributor, vortex crushing chamber, impeller body, main shaft assembly, base, transmission device and motor. It is a new type of medium and fine stone crushing equipment currently developed, with the characteristics of low energy consumption, small equipment size and shaping function.

[0003] The existing impact-type mining sand making machine has a large weight and will produce strong vibrations during its operation. Since its mounting base is rigidly connected to the ground, its base is generally welded with I-beams or channel steels, and its shock absorption performance is extremely poor. Strong vibrations can damage the internal parts of the sand making machine, affect the functions of instruments and equipment, reduce the working accuracy of mechanical equipment, aggravate component wear, and even cause structural fatigue damage, thus reducing the service life of the sand making machine. Utility Model Content

[0004] The utility model aims to provide a vibration-damping base for a mining sand making machine to solve the technical problems raised in the background technology.

[0006] Preferably, the size of the shock absorbing plate is smaller than the size of the shock absorbing cavity, and the size of the supporting platform is larger than the size of the shock absorbing cavity.

[0007] Preferably, the damping shock absorbing assembly includes a top plate and a bottom plate, a boss is provided in the middle bottom portion of the top plate, a cylindrical cavity is provided in the middle bottom portion of the boss, slots are provided on both sides of the cylindrical cavity, a rubber block corresponding to the cylindrical cavity is provided in the middle portion of the upper surface of the bottom plate, a butterfly spring group is provided between the top of the rubber block and the top inner wall of the cylindrical cavity, plug rods corresponding to the slots are provided on both sides of the upper surface of the bottom plate, and a shock absorbing spring is provided between the top of the plug rod and the top inner wall of the slot.

[0008] Preferably, the limit shock absorbing assembly includes a connecting rod, the top of the connecting rod is rotatably connected to the side wall of the shock absorbing plate through a rotating shaft, the bottom of the connecting rod is rotatably connected to a slider through a rotating shaft, the inner side wall of the shock absorbing cavity is provided with a vertically distributed groove, a vertically distributed sliding rod is installed in the groove, the slider is sleeved on the sliding rod and connected to the sliding rod for up and down sliding, and a buffer spring is sleeved on the sliding rod, the top of the buffer spring is connected to the bottom of the slider, and the bottom is connected to the bottom inner wall of the groove.

[0011] The utility model of a mining sand making machine vibration reduction base has the following advantages:

[0012] 1. The utility model sets a damping shock-absorbing component to make it have good longitudinal and lateral shock-absorbing effects, introduces the butterfly spring in general machinery, and improves the ability of the damping shock-absorbing component to absorb large-amplitude longitudinal impact vibration. The forces of the rubber block and the butterfly spring group are coordinated instead of restricting each other, so that the vibration-damping base has a good shock-absorbing effect, thereby extending the service life of the sand making machine.

[0013] 2. When the support platform and the shock absorbing plate move downward due to vibration, the damping shock absorbing assembly and the support spring generate a buffering force on the support platform and the shock absorbing plate, thereby reducing shock. The connecting rods connected by rotation on both sides of the shock absorbing plate can cooperate with the sliding rod, the slider and the buffer spring to prevent the shock absorbing plate from shaking left and right. This ensures the stability of the shock absorbing plate while reducing vibration of the shock absorbing plate, thereby improving the shock absorbing effect of the shock absorbing plate.

[0014] 3. The setting of four legs provides a good supporting effect on the positioning seat, forming a stable triangular structure between the legs, the positioning seat and the ground, which can effectively prevent the vibration-damping base from moving at will during the operation of the sand making machine, thereby ensuring the stable operation of the equipment.
