Description

Technical Field

[0001] This utility model patent relates to an impact crusher, and more particularly to a novel high-utilization adjustable crusher impact hammer used in conjunction with an impact crusher. Background Technology

[0002] An impact crusher is a vertical shaft impact crusher primarily used for fine crushing of materials, including models such as sand making crushers and micro powder crushers. Material entering the impact crusher is evenly distributed by a feeding cone. Then, the centrifugal force of the rotor propels the material against the impact hammers around the crushing chamber, achieving the purpose of crushing. Currently, the impact hammers in existing impact crushers are generally suspended directly around the crushing chamber or fixed to it. Since the hammers cannot move, they wear easily under the strong impact of the material being crushed. When the hammers wear to a certain extent, the diameter of the crushing chamber increases, and the distance between the hammers and the impeller increases. This reduces the impact force of the material thrown from the impeller onto the hammers, thus decreasing the crushing capacity. Summary of the Invention

[0003] Therefore, this utility model designs a new type of high-utilization adjustable impact hammer for sand making machines. The impact hammer of the sand making machine is designed to be adjustable along the radius of the crushing chamber of the sand making machine, so that the distance between the impact hammer and the impeller around the crushing chamber of the sand making machine can be infinitely adjusted. By conveniently adjusting the distance between the impact hammer and the impeller of the sand making machine from outside the sand making machine, the fine crushing capacity of the sand making machine is guaranteed and the working efficiency of the sand making machine is improved.

[0004] The objective of this utility model is achieved through the following means:

[0005] A novel high-utilization adjustable impact hammer for a sand making machine includes an impact hammer for a sand making machine. An upper adjustment hole is provided at the top of the impact hammer, and an upper support rod is inserted into the upper adjustment hole. The top of the upper support rod is fixed to the sand making machine housing via a connecting rod. An adjustment screw hole is provided in the middle of the impact hammer, and the adjustment screw passes through the sand making machine housing and is installed in the adjustment screw hole. The bottom of the impact hammer is slidably mounted on a hammer support plate. A lower adjustment hole is provided at the bottom of the impact hammer, and a lower support rod is installed on the sand making machine housing. An adjustment hole corresponding to the lower adjustment hole is provided on the hammer support plate, and the lower support rod passes through the adjustment hole and is assembled in the lower adjustment hole.

[0006] The aforementioned novel high-utilization adjustable sand making machine impact hammer has its connecting rod fixed to the sand making machine casing by connecting bolts.

[0007] The aforementioned novel high-utilization adjustable sand making machine impact hammer has a groove on the hammer support plate that matches the bottom of the sand making machine impact hammer, and the bottom of the sand making impact hammer is slidably installed in the groove.

[0008] The aforementioned novel high-utilization adjustable sander impact hammer has upper and lower adjustment holes that are both strip-shaped holes, and the adjustment path of the strip-shaped holes is parallel to the adjustment path of the lead screw.

[0009] Compared with the prior art, the present invention has the following technical effects:

[0010] This invention allows for stepless adjustment of the distance between the impact hammers and the impeller around the crushing chamber of a sand making machine. By conveniently adjusting this distance from outside the machine, the fine crushing capacity of the sand making machine is guaranteed, improving its working efficiency.

[0018] The following is in conjunction with the appendix Figures 1-3 The structure and working process of this utility model will be described in detail.

[0019] Combination Figures 1-3 The specific structure of this utility model is described in detail.

[0020] A novel, highly efficient, adjustable impact hammer for sand making machines includes an impact hammer 1, which is an impact device installed around the crushing chamber of a sand making machine to crush the raw materials. The raw materials ejected from the impeller outlet are impacted at high speed onto its working surface under centrifugal force, causing them to be finely crushed. However, the impact hammer also experiences wear over long-term operation. To maintain a constant distance between the impact hammer and the impeller, it is designed to be adjustable along the radius of the crushing chamber. The adjustment structure includes an upper adjustment hole 8 on the upper part of the impact hammer of the sand making machine. An upper support rod 2 is inserted into the upper adjustment hole, and the top of the upper support rod is fixed to the sand making machine housing 5 by a connecting rod. An adjustment screw hole 9 is provided in the middle of the impact hammer, and an adjustment screw 4 passes through the sand making machine housing and is installed in the adjustment screw hole. The bottom of the impact hammer is slidably mounted on the hammer support plate 6. A lower adjustment hole 10 is provided at the bottom of the impact hammer, and a lower support rod 7 is installed on the sand making machine housing. An adjustment hole corresponding to the lower adjustment hole is provided on the hammer support plate, and the lower support rod passes through the adjustment hole and is assembled in the lower adjustment hole. The upper support rod 2 is the upper device of the impact hammer in the sand making machine impact hammer adjustment mechanism. Its main function is to support and fix the impact hammer inside the crushing chamber of the sand making machine to prevent its circumferential displacement. Its size is determined according to the different models of sand making machines and the size of the impact hammer. The adjusting screw 4 allows the impact hammer 1 of the sand making machine to move a certain distance along the radius of the crushing chamber. The distance between the impact hammer 1 and the impeller of the sand making machine is adjusted by rotating the two screws and tightening the nuts. The lower support rod 7 is the lower fixing device of the impact hammer in the impact hammer adjustment mechanism; its main function is to support the impact hammer inside the crushing chamber and prevent circumferential displacement. The upper adjusting hole 8 is an elongated hole on the upper part of the impact hammer 1, which cooperates with the upper support rod 2 to support the impact hammer 1 in moving along the radius of the crushing chamber. The connecting screw hole 9 is the screw hole for fixing the adjusting screw 4 on the back of the working surface in the middle of the impact hammer 1. The lower adjusting hole 10 is a strip-shaped hole on the lower part of the impact hammer 1, which cooperates with the lower support rod 7 to support the impact hammer 1 in moving along the radius of the crushing chamber.

[0021] The novel high-utilization adjustable impact hammer for a sand making machine described in this utility model has a connecting rod fixed to the sand making machine housing by connecting bolts 3. Connecting bolts 3 are a fixing structure that secures the impact hammer to the inner wall of the crusher housing. This ensures the impact hammer is connected to the crusher housing, allowing it to operate.

[0022] The novel high-utilization adjustable impact hammer of this utility model features a sliding groove on the hammer support plate that matches the bottom of the impact hammer of the sand making machine. The bottom of the impact hammer is slidably installed within the sliding groove. The hammer support plate 6 is a flat plate structure connected to the sand making machine casing 5. Its main function is to support the impact hammer of the sand making machine, allowing the impact hammer 1 to be supported on it, and it can move slightly radially towards the crushing chamber during adjustment.

[0023] The novel high-utilization adjustable sander impact hammer of this utility model has both upper and lower adjustment holes that are strip-shaped holes, and the adjustment path of the strip-shaped holes is parallel to the adjustment path of the lead screw.

[0024] This utility model designs a new type of impact hammer and impact hammer adjustment mechanism for a sand making machine based on the structural characteristics of the impact hammer and the maximum failure distance after use. The improvement points are as follows:

[0025] 1. The upper and lower fixing pin holes of the impact hammer in the sand making machine are designed as strip holes instead of round holes. This allows the upper and lower adjusting rods to move within the strip holes along the radius of the crushing chamber of the sand making machine, providing a fixing function in the left and right directions. This allows the impact hammer to move inward along the radius of the crushing chamber, enabling the impact hammer to be adjusted in the radius of the crushing chamber. As a result, even after the working surface of the impact hammer wears, it can move inward, ensuring that the distance between the impact hammer and the impeller remains relatively constant. This maintains the fine crushing capacity of the sand making machine and improves its working efficiency.

[0026] 2. A connecting threaded hole is provided in the middle of the impact hammer of the sand making machine, which cooperates with the adjustment mechanism of the impact hammer around the crushing chamber of the sand making machine, so that the impact hammer moves inward along the radius of the crushing chamber. Since the adjustment screw can achieve stepless adjustment, the impact hammer can also be adjusted accordingly according to the adjustment distance of the screw.

[0027] 3. The two adjusting screws with tightened nuts are designed outside the crushing chamber. This allows for convenient manual adjustment of the inward movement distance of the impact hammers from outside the equipment without opening the crushing chamber. The length of the adjusting screw protruding from the machine indicates the adjustment distance of the impact hammers. If the distance between each impact hammer and the adjusting screw is approximately the same, it indicates that the distance between each impact hammer and the impeller is approximately the same.

[0028] This utility model features radial adjustment via an upper adjustment hole and an upper support rod at the top, radial adjustment via an adjusting screw and a connecting screw hole at the middle, and radial adjustment via a lower adjustment hole and a lower support rod at the bottom. When adjusting the impact hammer of the sand making machine, adjusting the adjusting screw on the outside of the sand making machine casing causes the screw to press tightly against the impact hammer and move it towards the impeller. Simultaneously, the upper and lower parts of the impact hammer are adjusted synchronously, achieving overall adjustment of the impact hammer.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
