Description

Technical Field

[0001] The utility model relates to the technical field of ore processing, in particular to a tooth roll structure of a high-calcium stone crusher. Background Art

[0002] The double-tooth roll crusher is a commonly used device for high-calcium stone crushing. It crushes the high-calcium stone to be processed by two oppositely rotating tooth rolls that bite the stone and break it into small pieces of the target size. In the prior art, the crushing teeth on the surface of the tooth rolls are all of the same length, and the crushing teeth of the two tooth rolls are interlaced and bite each other. Although the crushing teeth are arranged on the surface of the two tooth rolls, the distribution of the crushing teeth on the surface is uniform. If there is a relatively large and smooth-surfaced stone, neither of the two relatively rotating tooth rolls can bite the stone. During the rotation of the tooth rolls, the stone also rotates freely between the two tooth rolls, resulting in "idle rotation" between the two tooth rolls, and the corresponding stone cannot be crushed. In the prior art, there is no technical solution to solve the above problems, and only in the subsequent feeding process, by the impact and pressing of the subsequent stone, the contact force between the idle-rotating stone and the tooth roll is increased to complete the crushing operation. Content of the Utility Model

[0003] The purpose of the utility model is to provide a tooth roll structure of a high-calcium stone crusher to solve the above problems. Among the many technical solutions provided by the utility model, the preferred technical solution has the technical effects of forming a depression at the short teeth through the cooperation of long teeth, increasing the contact area with the stone, and thus realizing the stable crushing of the stone, as described in detail below.

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope protected by the present utility model.

[0021] See Figures 1-3 As shown, the present utility model provides a toothed roll structure for a high-calcium stone crusher, which includes a crushing box 1 and an anti-idling toothed roll group 2. A feeding port 3 is arranged at the top of the crushing box 1, and the anti-idling toothed roll group 2 is arranged in the crushing box 1, and the feeding port 3 is directly above the anti-idling toothed roll group 2;

[0022] The anti-idling toothed roll group 2 is composed of two toothed rolls rotating towards each other. At least one of the toothed roll surfaces is provided with a groove structure. After the groove structure is set, during the rotation of the toothed roll, when the stone raw material reaches the groove position, due to the change in the contact angle with the toothed roll surface, the biting force at the corresponding position can be increased, thereby ensuring the stable crushing of the stone; on the other hand, after the stone is stuck in the groove, its position has a greater force to hold the stone compared to the toothed roll with evenly distributed surface crushing teeth. During the rotation of the other toothed roll, the crushing force that the stone can withstand is also greater. Therefore, the stone can also be more easily broken;

[0023] The anti-idling toothed roll group 2 includes a first toothed roll 21 and a second toothed roll 22. A plurality of rows of first crushing teeth are arranged on the circumferential surface of the first toothed roll 21, and the distance between adjacent rows of the first crushing teeth is equal. A plurality of rows of second crushing teeth are arranged on the circumferential surface of the second toothed roll 22, and the distance between adjacent rows of the second crushing teeth is equal; The first crushing teeth are composed of a first crushing long tooth 21a and a first anti-rotation short tooth 21b. The groove refers to the position where the first anti-rotation short tooth 21b is set, and at least one row of the first anti-rotation short tooth 21b is set; The height of the first anti-rotation short tooth 21b is 1 / 2 - 2 / 3 of the first crushing long tooth 21a. Since the height of the first anti-rotation short tooth 21b is relatively low, an axial groove can be formed on the surface of the first toothed roll 21, so that when cooperating with the second toothed roll 22, more stable biting can be provided, thereby ensuring the crushing efficiency of the stone;

[0024] The second crushing teeth are composed of a second crushing long tooth 22a and a second anti-rotation short tooth 22b, and at least one row of the second anti-rotation short tooth 22b is set; The height of the second anti-rotation short tooth 22b is 1 / 2 - 2 / 3 of the second crushing long tooth 22a. The surface structure of the second toothed roll 22 is the same as that of the first toothed roll 21. A groove is also formed on the surface of the first toothed roll 21 through the second anti-rotation short tooth 22b, so that the stone can be stuck at the groove position, and the stone can be stably bitten and broken.

[0025] With the above structure, after the stone material is fed into the crushing box 1 through the feeding port 3, it falls in the middle of the anti-idle tooth roller group 2. During the falling process of the high-calcium stone raw material, through the anti-idle structure, it can prevent round or relatively large stone raw materials from idling inside the crushing box 1, improving the crushing efficiency of the high-calcium stone material; by arranging the first anti-rotation short teeth 21b on the outer side of the first tooth roller 21, grooves can be formed on the surface of the first tooth roller 21. During the relative rotation of the first tooth roller 21 and the second tooth roller 22, when the stone material falls and reaches the first anti-rotation short teeth 21b, the stone can be stuck into the depression, increasing the biting angle after the cooperation of the first tooth roller 21 and the second tooth roller 22, thereby promoting the biting of the stone with the second tooth roller 22 and reducing the occurrence of idling; the function of the second anti-rotation short teeth 22b is the same as that of the first anti-rotation short teeth 21b, and both can increase the biting angle of the cooperating stone when contacting the stone, realizing the stable biting and crushing of the stone.

[0026] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
