Description

Technical Field

[0001] This utility model relates to the technical field of limestone reclaiming machines for cement production, specifically to a rake tooth structure for a bridge-type reclaimer and a bridge-type reclaimer rake. Background Technology

[0002] Most limestone reclaimers are bridge-type reclaimers, which have advantages such as stable structure, high efficiency, wide coverage, high degree of automation, reliable operation, and strong adaptability. Limestone is an indispensable material in cement raw meal production, accounting for 80%-90% or more. Bridge-type reclaimers are widely used in limestone extraction, and can be considered the basic equipment in cement raw meal production.

[0003] During the material handling process of the reclaimer, the rake teeth of the bridge reclaimer come into direct contact with the material. Because the rake drives the rake teeth in reciprocating motion, the rake teeth may loosen or fall off, posing significant equipment and personal safety hazards and causing increasing problems for users. Therefore, it is necessary to develop a robust and reliable rake tooth structure for the reclaimer to ensure safe operation of the equipment. Utility Model Content

[0004] This utility model provides a rake tooth structure for a bridge-type material reclaimer and a bridge-type material reclaimer rake cart. By changing the shape of the rake teeth, the force of contact with the material is reduced, thus reducing the risk of rake teeth loosening or falling off. At the same time, the connection method between the rake teeth and the rake cart is changed to ensure that the installed rake teeth are firmly connected, effectively reducing the possibility of rake teeth falling off.

[0005] A rake tooth structure for a bridge-type material reclaimer rake cart includes:

[0006] link;

[0007] The rake teeth, comprising a plurality of teeth arranged along the length of the connecting rod, each rake tooth including a rake portion whose size increases outward from the end connected to the connecting rod to form a conical structure, and a connecting portion located at the end of the rake portion; and

[0008] A fixing element is provided at the end of the rake teeth away from the connecting rod.

[0009] Preferably, the plurality of rake teeth are evenly distributed along the length of the connecting rod.

[0010] Preferably, the rake portion has inclined rake surfaces on both sides, and the end of the rake portion near the connecting rod has a rounded transition.

[0011] Preferably, the connecting portion has a groove.

[0012] Preferably, the fixing member is a square steel bar distributed parallel to the connecting rod.

[0013] A bridge-type material reclaimer rake trolley includes the aforementioned rake tooth structure.

[0014] Preferably, the fixing members are evenly distributed along the rake frame of the rake.

[0015] As can be seen from the above technical solution, the present invention has the following beneficial effects: The rake teeth in the present invention are set on the connecting rod, and the end of the rake teeth away from the connecting rod is fixed to the rake cart by a fixing member. Since the rake teeth include a rake-picking part and a connecting part, and the rake-picking part is a conical structure, when working through the rake tooth structure, the rake-picking surface can be used to contact the material, which can reduce the resistance between the rake cart and the material during the reciprocating motion and reduce the risk of the rake teeth loosening or falling off; in addition, the connecting part at the tail of the rake teeth is connected to the rake cart by a fixing member, which fits stably and welds firmly, effectively reducing the possibility of rake teeth falling off.

[0021] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: (Refer to...) Figure 1 , Figure 2 , Figure 3A rake tooth structure for a bridge-type material reclaimer includes a connecting rod 10, rake teeth 20, and a fixing member 30. Further, the number of rake teeth is multiple, and the multiple rake teeth 20 are spaced apart along the length of the connecting rod 10. Specifically, each rake tooth includes a rake-taking section 210 and a connecting section. One end of the rake-taking section 210 is fixedly connected to the connecting rod 10, and the size of the rake-taking section 210 gradually increases outward from the end connected to the connecting rod 10, forming a conical structure. Thus, the conical structure of the rake-taking section 210 has a small-sized end and a large-sized end. Simultaneously, the connecting section is integrally formed with the rake-taking section and is located at the end of the rake-taking section. The fixing member 30... The fixing component is located at the end of the rake tooth 20 away from the connecting rod. In use, multiple conical rake teeth are mounted on the connecting rod, and the end of the rake tooth away from the connecting rod is connected to the fixing component. At the same time, the fixing component is fixed to the rake cart. Since the rake tooth includes a rake-grabbing part and a connecting part, and the rake-grabbing part is a conical structure, the rake-grabbing surface can contact the material when working through this rake tooth structure. Due to the special shape of the rake-grabbing part, the resistance between the rake cart and the material during the reciprocating motion can be reduced, thus reducing the risk of rake teeth loosening or falling off. In addition, the connecting part at the tail of the rake tooth is connected to the rake cart through the fixing component, which fits stably and welds firmly, effectively reducing the possibility of rake tooth falling off.

[0023] In order to connect the rake teeth 20 and the connecting rod 10, in this embodiment, welding can be used to fix the connecting rod 10 and the rake teeth 20.

[0024] Reference Figure 1 As a preferred technical solution in this embodiment, the plurality of rake teeth 20 are evenly distributed along the length direction of the connecting rod 10, that is, the rake teeth 20 in this embodiment are evenly spaced along the connecting rod to form a rake tooth structure with equal spacing on the connecting rod.

[0025] Reference Figure 2 , Figure 3 In some embodiments, the rake section has inclined rake surfaces on both sides, and the end of the rake section near the connecting rod 10 is rounded. Specifically, in this embodiment, the included angle between the two rake surfaces is 14°. In this way, during the material rakeing process, the rake section can use its rake surfaces to make inclined contact with the material, reducing the resistance generated by vertical contact with the material, thereby reducing the running resistance during material rakeing, reducing the probability of rake teeth detachment, and reducing the possibility of failure of the material handling machine body and downstream equipment.

[0026] In some embodiments, the connecting part is provided with a groove 220. It should be noted that the groove 220 in this embodiment is a rectangular groove, which can be fitted onto the outside of the fixing member 30 as a whole, and the two can be fixed by welding.

[0027] Furthermore, the fixing member 30 is a square steel bar distributed parallel to the connecting rod 10, and the square steel bar is fixedly installed on the rake trolley. In this way, the size of the groove can be adapted to the shape of the square steel bar, thereby achieving a fit between the two. Moreover, the square steel bar is welded as a whole to the rake trolley, which can realize the indirect connection between the rake tooth structure of the bridge reclaimer and the rake trolley. In this way, when replacing the rake tooth structure, only the corresponding square steel bar needs to be replaced, which facilitates the replacement of the rake tooth structure.

[0028] Reference Figure 4 This utility model also provides a bridge-type material reclaimer rake trolley, including the aforementioned rake tooth structure. This utilizes the inclined rake portion in the rake tooth structure to reduce the resistance when the rake trolley contacts the material during reciprocating motion. Simultaneously, the rake teeth are connected to the rake trolley via fixing members and are firmly welded, effectively reducing the possibility of rake tooth detachment. It should be noted that, to improve the material reclaiming effect of the rake trolley, multiple fixing members can be evenly distributed along the rake frame of the rake trolley.

[0029] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
