Description

Technical Field

[0001] This utility model relates to the field of impact crusher technology, and more specifically, to a cascade mechanism for a vertical shaft impact crusher. Background Technology

[0002] An impact crusher is a device that uses high-speed impact energy to crush materials and is widely used in mining, building materials, metallurgy, chemical and other industries. Its working principle is that the high-speed rotation of the rotor drives the hammers or plate hammers to impact the material, causing the material to be crushed under the action of impact force, shear force and mutual collision. It is mainly divided into: impact crusher, vertical shaft impact crusher and hammer crusher. The vertical shaft impact crusher causes the material to be thrown in the high-speed rotating impeller, colliding and crushing with the surrounding guard plates or the material itself. It is suitable for sand making or high-grade aggregate production, and the finished product has a uniform particle size.

[0003] With the continuous development of industry, the performance requirements for crushing equipment are increasing. Traditional vertical shaft impact crushers often have problems such as low crushing efficiency and uneven product particle size when processing materials. Traditional vertical shaft impact sand making machines feed from the center of the impeller. If all the material passes through the center of the impeller during material shaping, the powder content of the material will increase, the shaping effect will be poor, and the wear parts will wear out quickly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 A cascading mechanism for a vertical shaft impact crusher includes: a frame 5, a crushing chamber 1 detachably connected to the top surface of the frame 5, a feed hopper 2 detachably connected to the top surface of the crushing chamber 1, an upper steel plate fixedly connected between the inner walls of the feed hopper 2, and three through holes on the top surface of the upper steel plate; and a cascading assembly, which is disposed inside the crushing chamber 1 to improve crushing efficiency.

[0025] In a specific embodiment of this utility model, a crushing chamber 1 is installed on a frame 5, and a feed hopper 2 is installed at the input end of the crushing chamber 1. An upper steel plate is installed on the inner wall of the feed hopper 2, and the upper steel plate fixes the cascading assembly, i.e., three adjusting rods 6 are inserted into corresponding through holes, and their height is adjusted according to requirements. Then, a fixing pin is installed in the pin hole to fix the three adjusting rods 6, thereby fixing the cascading assembly. When the material needs to be shaped, the baffle 8 on the support plate 9 is closed. When the material enters the feed hopper 2, the material will pass through the inner hole of the feed hopper 2 and reach the support plate 9. At the same time, since the feed rate is much greater than the throughput of the through hole of the support plate 9, some material will enter the crushing chamber 1, and then some material will pass through the support plate 9 and enter the impeller 4. The impeller 4 rotates at high speed and accelerates the material out, which will come into contact with the material entering the crushing chamber 1 for impact crushing. Then, they will impact the material lining of the crushing chamber 1 together, and after rebounding, impact the crusher obliquely upward. The material is ejected from the flow channel onto the impact guard plate at the top of chamber 1, forming a continuous curtain of material. This causes the material to undergo multiple impacts, friction, and grinding within the crushing chamber 1, achieving a crushing effect. Finally, the material falls into the discharge hopper by gravity. This effectively accelerates the material to a high speed, causing it to collide violently with other materials and crushing components within the crushing chamber 1, thus achieving rapid crushing. At the same time, it ensures uniform particle size, improving product quality. During long-term operation, it maintains high-efficiency crushing performance, reducing equipment maintenance costs and downtime. By optimizing the drop angle and flow control, it ensures that the material receives sufficient impact and grinding within the crushing chamber 1, thereby improving crushing efficiency and increasing output. The shaped material has rounded particles without flaky shapes, meeting the requirements of manufactured sand, reducing the output of fine powder, and lowering the powder content of the material. While meeting production requirements, it also reduces impeller 4 wear, saving costs and reducing energy consumption.

[0026] Specifically, the waterfall assembly includes a distribution plate 3 and an impeller 4. The distribution plate 3 includes a support plate 9 and three adjusting rods 6. The support plate 9 is located inside the feed hopper 2. The three adjusting rods 6 are all fixedly connected to the top surface of the support plate 9. The three adjusting rods 6 are respectively matched with the corresponding through holes. The impeller 4 is installed on the top surface of the crushing chamber 1.

[0027] In this embodiment, the material is diverted by the distribution plate 3, which can control the amount of material entering the impeller 4, thereby adjusting the crushing process. The impeller 4 is used to accelerate the material, causing it to be ejected faster and collide with other materials.

[0028] Specifically, the outer walls of the three adjusting rods 6 are provided with multiple pin holes.

[0029] In this embodiment, a pin is installed through a pin hole to adjust the installation height of the adjusting rod 6.

[0030] Specifically, two sets of rotating hinges 7 are installed on the top surface of the support plate 9, and each set of rotating hinges 7 has two hinges.

[0031] In this embodiment, a baffle 8 is set by rotating the hinge 7, and the baffle 8 adjusts the material distribution plate 3 to control the amount of material falling.

[0032] Specifically, a baffle 8 is rotatably connected between the outer walls of one side of each of the two rotating hinges 7.

[0033] In this embodiment, the material distribution plate 3 is adjusted by the baffle 8, and the baffle 8 can be adjusted by rotating the hinge 7.

[0034] Specifically, the top surfaces of both baffles 8 are provided with guide ports, and the top surfaces of the support plate 9 are provided with through ports.

[0035] In this embodiment, the material falls in a closed state through the guide port, and the through hole on the top surface of the support plate 9 is the inner hole of the distribution plate 3.

[0036] Working principle: The crushing chamber 1 is installed on the frame 5. The feed hopper 2 is installed at the input end of the crushing chamber 1. An upper steel plate is set on the inner wall of the feed hopper 2, and the cascading assembly is fixed on the upper steel plate. That is, three adjusting rods 6 are inserted into the corresponding through holes. Then, their height is adjusted according to the requirements. Then, a fixing pin is set in the pin hole to fix the three adjusting rods 6, thus fixing the cascading assembly. When the material needs to be shaped, the baffle 8 on the support plate 9 is closed. When the material enters the feed hopper 2, the material will pass through the inner hole of the feed hopper 2 and reach the support plate 9. At the same time, since the feed rate is much greater than the throughput of the through hole of the support plate 9, some material will enter the crushing chamber 1, and then some material will pass through the support plate 9 and enter the impeller 4. The impeller 4 rotates at high speed and agitates the material. The material is rapidly ejected and comes into contact with the material entering the crushing chamber 1, undergoing impact crushing. It then impacts the lining of the crushing chamber 1 together, rebounds, and impacts the top impact guard plate of the crushing chamber 1 before moving downwards. The material ejected from the flow channel forms a continuous curtain of material, causing multiple impacts, friction, and grinding within the crushing chamber, thus achieving the crushing effect. Finally, it falls by gravity into the discharge hopper. This process effectively accelerates the material to a high speed, causing it to collide violently with other materials and crushing components within the crushing chamber 1, achieving rapid crushing while ensuring uniform particle size and improving product quality. During long-term operation, it maintains high-efficiency crushing performance, reducing equipment maintenance costs and downtime.

[0037] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
