Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a shock-absorbing impact sand making machine. Background Technology

[0002] In the concrete production industry, impact crushers are key equipment, playing a crucial role in the production of sand and gravel aggregates. Existing crushers, such as the vertical shaft impact crusher disclosed in CN201510140400.7 and the fine impact crusher disclosed in CN202310046426.X, generally use anchor bolts to fix the crusher's legs to concrete foundations and other corresponding facilities. However, impact crushers generate strong vibrations during operation. This high-frequency and large-amplitude vibration energy is continuously transmitted to the foundation, easily causing fatigue damage to the foundation structure, leading to cracks or even breakage. Once the foundation is damaged, the stability of the crusher is compromised, and it is prone to displacement. This not only affects the continuity and stability of the crushing operation, leading to a significant decrease in production efficiency, but may also cause equipment failure, increasing maintenance costs and downtime, seriously hindering the smooth progress of the entire concrete production process. Therefore, how to effectively reduce the impact of vibration from impact crushers on the foundation has become a pressing technical problem to be solved in this field. Utility Model Content

[0003] The purpose of this utility model is to provide a shock-absorbing impact sand making machine. By adding shock-absorbing support seats to the support legs, the vibration energy generated during the operation of the sand making machine can be effectively absorbed, the transmission of vibration to the foundation can be reduced, the foundation can be prevented from cracking and the sand making machine from shifting, and the stable and efficient operation of the sand making machine can be guaranteed.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A shock-absorbing impact crusher includes an impact crusher, wherein each of the four legs of the impact crusher is connected to a shock-absorbing support.

[0006] The vibration damping support includes a column fixed below the support legs, the column being inserted into the cylinder bore of the base, and a sealing sleeve between the column and the cylinder bore; the cavity formed by the sealing sleeve, the base, and the column is filled with liquid. In use, the base is fixed to the corresponding foundation. The vibration generated by the impact crusher during operation is transmitted to the column 21 through the support legs 11. Because there is double vibration damping between the column 21 and the base 22—one layer being the sealing sleeve and the other being the liquid—the vibration energy transmitted from the column can be significantly absorbed through the sealing sleeve and the liquid, thereby effectively reducing the amount of vibration transmitted to the base, thus effectively reducing the impact of the base on the corresponding foundation, and simultaneously reducing the noise generated by the vibration.

[0007] The present invention is further configured such that a shock-absorbing pad is sandwiched between the column and the support leg. The shock-absorbing pad can initially reduce the vibration energy transmitted from the support leg to the column, and can further reduce the shock-absorbing load in the next stage.

[0008] The present invention is further configured such that: the lower part of the column is formed with a countersunk hole;

[0009] The sealing sleeve includes an integrally formed outer sleeve, inner sleeve, and bottom sleeve. The outer sleeve covers the lower outer wall of the column, the inner sleeve covers the inner wall of the countersunk hole, and the bottom sleeve is inserted into the bottom of the column, which can increase the bonding ability between the sealing sleeve and the column.

[0010] The outer sleeve is formed with multiple raised rings arranged vertically. The raised rings are attached to the inner wall of the cylinder bore. Multiple raised rings can form a multi-layer seal, which can effectively prevent liquid from leaking out of the cylinder bore.

[0011] The present invention is further configured such that the bottom of the cylinder holes of two adjacent shock-absorbing support seats are connected by a connecting pipe. The connecting pipe can make the pressure-bearing capacity of the four cylinder holes the same. Even if leakage or unilateral force occurs, the liquid volume of each cylinder hole can be adjusted to balance the force on the four legs.

[0012] The present invention is further configured such that: scale lines are formed on the outer wall of the column, and the height of the column relative to the base can be known through the scale lines, thereby also showing the lifting height of the entire sand making machine and the remaining amount of liquid in the cylinder bore.

[0013] The present invention is further configured such that: the upper part of the column is formed with a filling hole and a liquid passage hole connecting the inner end of the filling hole and the sink hole;

[0014] The inner end of the filling hole is provided with a one-way valve mechanism;

[0015] A removable plug is screwed to the outer end of the filling hole. When the liquid in the cylinder bore is less than a certain amount, the plug is removed and a corresponding pump is connected to replenish the liquid from the outside into the cylinder bore. The one-way valve mechanism can prevent the liquid in the cylinder bore from overflowing, thus facilitating the removal and installation of the plug and the replenishment of liquid.

[0016] The outstanding effect of this utility model is:

[0017] Compared with existing technologies, the dual shock absorption design of the sealing sleeve and liquid can significantly absorb the vibration energy transmitted by the column. The sealing sleeve has good elastic deformation capability, which can buffer the vibration impact, while the liquid flows under pressure in the sealed space, which can convert the vibration kinetic energy into other forms of energy such as heat energy, effectively reducing the amount of vibration transmitted to the base, significantly reducing the impact of the sand making machine vibration on the foundation, avoiding the foundation from cracking due to long-term vibration, and providing a solid guarantee for the stable operation of the sand making machine.

[0018] The scale lines on the outer wall of the column allow operators to intuitively understand the height change of the column relative to the base, thereby grasping the lifting height of the sand making machine and the remaining liquid in the cylinder bore, and realizing real-time monitoring of the equipment's operating status. In addition, the combined design of the filling hole, liquid passage hole, one-way valve mechanism and plug makes the liquid replenishment operation simple and easy. The one-way valve mechanism can effectively prevent liquid overflow, ensuring the efficiency of liquid replenishment while reducing the difficulty and risk of maintenance work, and improving the convenience and safety of equipment maintenance.

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] The following is for reference Figures 1 to 3 The present invention will be described as follows:

[0029] A type of shock-absorbing impact crusher, such as Figure 1 As shown, it includes an impact crusher 1, and each of the four legs 11 of the impact crusher 1 is connected to a shock-absorbing support 2.

[0030] like Figure 2As shown, the shock-absorbing support 2 includes a column 21 fixed below the support leg 11. The column 21 is inserted into the cylinder bore 221 of the base 22, and a sealing sleeve 23 is provided between the column 21 and the cylinder bore 221. The cavity formed by the sealing sleeve 23, the base 22, and the column 21 is filled with liquid 24. In use, the base is fixed on the corresponding foundation. The vibration generated by the impact crusher during operation is transmitted to the column 21 through the support leg 11. Since there is double shock absorption between the column 21 and the base 22, one layer of shock absorption is the sealing sleeve, and the other layer of shock absorption is the liquid. The vibration energy transmitted from the column can be greatly absorbed through the sealing sleeve and the liquid, thereby effectively reducing the amount of vibration transmitted to the base, thus effectively reducing the impact of the base on the corresponding foundation, and at the same time reducing the noise generated by vibration.

[0031] The lower part of the column 21 is formed with a countersunk hole 211;

[0032] The sealing sleeve 23 includes an integrally formed outer sleeve 231, inner sleeve 232 and bottom sleeve 233. The outer sleeve 231 covers the lower outer wall of the column 21, the inner sleeve 232 covers the inner wall of the countersunk hole 211, and the bottom sleeve 233 is inserted into the bottom of the column 21, which can increase the bonding ability between the sealing sleeve and the column.

[0033] The outer sleeve 231 is formed with multiple raised rings 234 arranged vertically. The raised rings 234 are attached to the inner wall of the cylinder bore 221. Multiple raised rings can form a multi-layer seal, which can effectively prevent liquid from leaking out of the cylinder bore.

[0034] like Figure 1 , Figure 3 As shown, a shock-absorbing pad 25 is sandwiched between the column 21 and the support leg 11. The shock-absorbing pad 25 can initially reduce the vibration energy transmitted from the support leg to the column, and can further reduce the shock-absorbing load in the next stage.

[0035] The bottom of the cylinder bore 221 of two adjacent shock-absorbing support seats 2 is connected by a connecting pipe 26. The connecting pipe can make the pressure-bearing capacity of the four cylinder bores the same. Even if leakage or unilateral force occurs, the liquid volume of each cylinder bore can be adjusted to balance the force on the four legs.

[0036] The outer wall of the column 21 is formed with scale lines 212. The height of the column relative to the base can be known through the scale lines, and thus the lifting height of the entire sand making machine and the remaining amount of liquid in the cylinder bore can also be seen.

[0037] The upper part of the column 21 is formed with a filling hole 213 and a liquid passage hole 214 connecting the inner end of the filling hole 213 and the countersunk hole 211.

[0038] The inner end of the filling hole 213 is provided with a one-way valve mechanism 27;

[0039] A removable plug 28 is screwed to the outer end of the filling hole 213. When the liquid in the cylinder bore is less than a certain amount, the plug is removed and a corresponding pump is connected to replenish the liquid from the outside into the cylinder bore. The one-way valve mechanism can prevent the liquid in the cylinder bore from overflowing, thus facilitating the removal and installation of the plug and the replenishment of liquid.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
