Description

Technical Field

[0001] This utility model relates to the field of shovel teeth technology, and in particular to a shovel tooth for a combined feeder. Background Technology

[0002] In mineral processing, ball mills are crucial grinding equipment, and combined feeders are key components for feeding materials into the ball mill. The shovel teeth in the combined feeder can quickly cut into the ore layer, effectively assisting in feeding. In actual operation, the shovel teeth of the combined feeder must withstand the impact, compression, and friction of materials for extended periods. During the falling and conveying process of lumpy materials (especially high-hardness ores and granite), the tips and sides of the shovel teeth experience continuous wear. Traditional shovel teeth are mostly integral metal structures without dedicated protective designs, leading to problems such as worn-down tips and deformed sides after prolonged use, requiring frequent shutdowns for replacement.

[0003] More importantly, the material picked up by some of the current shovel teeth is prone to fall off during the movement of the shovel teeth, and some materials (such as clay and fine powder mixtures with high moisture content) are prone to sticking and accumulating on the surface of the shovel teeth. Traditional shovel teeth do not have a material storage and drainage structure, and the accumulated material will block the gap between the shovel teeth and the equipment housing. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a combined feeder shovel tooth.

[0005] The present invention adopts the following technical solution.

[0006] A combined feeder shovel tooth includes a shovel tooth body and connecting plates. Two connecting plates are provided on both sides of the shovel tooth body. A secondary tooth is connected to one end of the shovel tooth body. A shovel tooth protective sleeve is welded to the outer side of the shovel tooth body. A secondary tooth protective sleeve is welded to the end of the shovel tooth protective sleeve near the secondary tooth. The secondary tooth protective sleeve covers the secondary tooth. A material storage part is provided on the inner side of the shovel tooth protective sleeve.

[0007] To improve efficiency when crushing ore layers, one side of the auxiliary tooth protective sleeve is an acute angle, and the acute angle faces away from the side of the shovel tooth protective sleeve.

[0008] To further improve the efficiency of crushing ore layers, two rows of crushing rods are connected to the upper and lower sides of the auxiliary tooth protective sleeve, and each crushing rod has a pointed end away from the auxiliary tooth protective sleeve.

[0009] To prevent the scooped material from falling off the shovel teeth, the storage section includes a storage baffle, a rotating rod, and two fixing rings. The rotating rod is connected to the shovel tooth protective sleeve and is located inside the shovel tooth protective sleeve. The storage baffle is fitted on the outside of the rotating rod and can swing relative to the rotating rod. The two fixing rings are fitted on the outside of the rotating rod and are located at both ends of the storage baffle.

[0010] Preferably, a limiting rod is provided on the inner side of the shovel tooth protective sleeve. The limiting rod is L-shaped and obliquely placed on the inner side of the shovel tooth protective sleeve, and the end of the limiting rod away from the shovel tooth protective sleeve abuts against the material storage baffle.

[0011] To extend the service life of the shovel teeth, the surface of the shovel teeth protective sleeve is provided with a slag discharge groove, and the surface of the material storage baffle is provided with a slag unloading groove. The slag unloading groove runs through the material storage baffle, and the slag discharge groove and the slag unloading groove are aligned.

[0012] To facilitate observation of the wear condition of the auxiliary tooth protective sleeve, reflective coatings are applied to both sides of the sleeve.

[0013] Beneficial effects: The combined feeder shovel teeth of this utility model can not only improve the efficiency of crushing ore layers, but also extend the service life of the shovel teeth body. At the same time, it is easy to observe the wear of the auxiliary tooth protective sleeve and replace it in time. More importantly, the cooperation between the material storage part and the shovel tooth protective sleeve can prevent the shoveled material from falling off the shovel teeth body.

Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Combination Figures 1-4 As shown, a combined feeder shovel tooth includes a shovel tooth body 1 and a connecting plate 2. Two connecting plates 2 are provided on both sides of the shovel tooth body 1. A secondary tooth 3 is connected to one end of the shovel tooth body 1. A shovel tooth protective sleeve 4 is welded to the outside of the shovel tooth body 1. A secondary tooth protective sleeve 5 is welded to the end of the shovel tooth protective sleeve 4 near the secondary tooth 3. The secondary tooth protective sleeve 5 wraps around the secondary tooth 3. A material storage part is provided on the inside of the shovel tooth protective sleeve 4.

[0022] One side of the auxiliary tooth protective sleeve 5 is an acute angle, and the acute angle faces away from the side of the shovel tooth protective sleeve 4.

[0023] Among them, the upper and lower sides of the auxiliary tooth protective sleeve 5 are respectively connected to two rows of crushing rods 6, and each crushing rod 6 has a pointed end away from the auxiliary tooth protective sleeve 5.

[0024] The material storage section includes a material storage baffle 7, a rotating rod 8, and two fixing rings 9. The rotating rod 8 is connected to the shovel tooth protective sleeve 4 and is located inside the shovel tooth protective sleeve 4. The material storage baffle 7 is fitted on the outside of the rotating rod 8 and can swing relative to the rotating rod 8. The two fixing rings 9 are fitted on the outside of the rotating rod 8 and are located at both ends of the material storage baffle 7.

[0025] The inner side of the shovel tooth protective sleeve 4 is provided with a limiting rod 10. The limiting rod 10 is L-shaped and is placed obliquely inside the shovel tooth protective sleeve 4. The end of the limiting rod 10 away from the shovel tooth protective sleeve 4 abuts against the material storage baffle 7.

[0026] The surface of the shovel tooth protective sleeve 4 is provided with a slag discharge groove 11, and the surface of the material storage baffle 7 is provided with a slag unloading groove 12. The slag unloading groove 12 penetrates the material storage baffle 7, and the slag discharge groove 11 and the slag unloading groove 12 are aligned.

[0027] The auxiliary tooth protective sleeve 5 has reflective coating 13 on both sides.

[0028] Among them, the shovel tooth protective sleeve 4 is made of multiple alloy wear-resistant plates spliced ​​together, and the alloy wear-resistant plates are welded by the overlay welding process.

[0029] When installing the shovel tooth protective sleeve 4, the pre-made alloy wear-resistant plate is cut into small pieces according to the predetermined size using a laser cutting machine. Then, stainless steel welding wire is used to weld these cut wear-resistant blocks onto the cast steel Mn13 shovel tooth body 1.

[0030] During the material-scooping process of the shovel tooth body 1, the acute angle of the auxiliary tooth protective sleeve 5 will first contact the ore layer and work together with the crushing rod 6 to crush the material (crushing the material to a size that can be loaded into the shovel tooth body 1). The scooped material pushes up the storage plate and moves towards the root of the shovel tooth body 1. After the storage plate resets, it abuts against the limit rod 10. During the movement of the shovel tooth body 1, the storage plate can block the material and prevent it from falling. At the same time, the mixture of clay and fine powder with high moisture content can be discharged through the slag discharge chute 11 and the slag unloading chute 12 to prevent the material from clogging the gap between the shovel tooth and the equipment shell.

[0031] During the use of the shovel tooth body 1, the wear condition of the auxiliary tooth protective sleeve 5 can be judged by observing the shape of the reflective coating 13, so as to facilitate timely replacement of the auxiliary tooth protective sleeve 5.

[0032] The combined feeder shovel teeth of this utility model can not only improve the efficiency of crushing ore layers, but also extend the service life of the shovel tooth body 1. At the same time, it is easy to observe the wear of the auxiliary tooth protective sleeve 5 and replace it in time. More importantly, the cooperation between the material storage part and the shovel tooth protective sleeve 4 can prevent the shoveled material from falling off the shovel tooth body 1.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
