Description

Technical Field

[0001] This utility model relates to the field of ball mill equipment technology, and in particular to a wear-resistant ball mill scoop head. Background Technology

[0002] Currently, the grinding and classification series composed of low-weir double-spiral classifiers adopts a single-stage closed-circuit process, consisting of a cylindrical cylinder, end caps, hollow shaft journals, grid plates, and a transmission device. The cylinder contains grinding media (steel balls, steel segments, etc.) and the material to be ground. The cylinder is driven to rotate by a transmission device (such as a motor or gears). Under the action of centrifugal force and friction, the grinding media rises with the cylinder. When the cylinder rotates to a certain height, the grinding media falls due to gravity, impacting and crushing the material inside the cylinder, breaking up large pieces. Simultaneously, the friction and grinding action between the grinding media and between the media and the cylinder liner further grinds the material into powder. The material enters the cylinder from the hollow shaft journal at the feed end, mixes with the grinding media as the cylinder rotates, and continuously undergoes a cycle of "lifting-falling-grinding" during the cylinder's rotation, gradually being pulverized.

[0003] However, during production, the return sand from the spiral classifier and the ore from the scoop box need to be fed into the ball mill. Therefore, a combined feeder is installed at the feed end of the ball mill. The scoop body of the combined feeder has a scoop head, which feeds the ore and slurry into the ball mill. Because the scoop head moves in a circular motion during operation, the top of the scoop head rubs against the ore, causing the scoop head to wear very quickly. Generally, the mill needs to be stopped and the scoop head replaced every half month or so. Moreover, the replaced scoop head cannot be repaired and must be scrapped, reducing its practicality. Ore entering the inside of the distributor can easily damage the inner shell, causing the distributor to break and become unusable, resulting in significant losses. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant ball mill spoon head, comprising: a feeding drum body, wherein two feeding spoon boxes are welded to the outer surface of the feeding drum body, connecting strips are welded to the outer surfaces of both sides of the two feeding spoon boxes, iron plates are welded to the other side of the two connecting strips, a spoon head body is welded to one side of the two iron plates, and multiple alloy drill bits are fixedly connected to the opposite side of the inner walls of the two iron plates.

[0005] The technical effect of adopting the above-mentioned further solution is as follows: the rotation of the feeding drum body drives the two feeding spoon boxes to rotate in a circle to dig out the ore. The iron plate is fixed by welding the connecting strip to both sides of the spoon head body. The spoon head body is welded and fixed to the iron plate. The alloy drill bit two buffers the collision of the ore entering the spoon head body, prevents the ore from damaging the inner surface of the spoon head body, and improves the service life of the spoon head body.

[0006] In a preferred embodiment, the inner walls of both spoon heads are fixedly connected with fixing strips, and the outer surfaces of both fixing strips are fixedly connected with multiple alloy drill bits.

[0007] The technical effect of adopting the above-mentioned further solution is that the fixing strip is welded to the alloy drill bit one through the spoon head body. Under the buffer of the alloy drill bit one, the contact surface between the spoon head body and the return sand material and its ore blocks is reduced, thereby increasing the service life of the spoon head body.

[0008] In a preferred embodiment, the inner surfaces of both spoon heads are machined with an oblique groove I, and the inner surfaces of both spoon heads are machined with an oblique groove II.

[0009] The technical effect of adopting the above-mentioned further solution is that: by machining and cutting oblique groove one and oblique groove two on the inner surface of the spoon head body, a wear-resistant area is formed, thereby increasing the service life of the spoon head body.

[0010] In a preferred embodiment, multiple connecting blocks are fixedly connected to the top of the two feeding spoon boxes, and the multiple connecting blocks are welded to the outer surface of one side of the two iron plates.

[0011] The technical effect of adopting the above-mentioned further solution is that the top of the spoon head body is connected by a connecting block to prevent the top from shaking.

[0012] In a preferred embodiment, the two feeding spoon boxes are provided with inner box cavities, the two connecting blocks are provided with two baffles, one side of each baffle is fixedly connected to a damper, and the outer surface of each damper is fitted with a spring.

[0013] The technical effect of adopting the above-mentioned further solution is that when the returned sand material and its ore blocks enter the inner box cavity, their impact force collides with the outer surface of the baffle. The impact force causes the damper and spring to contract and buffer the baffle, thereby protecting the inner shell of the feed spoon box.

[0014] In a preferred embodiment, the inner walls of both feeding spoon boxes are fixedly connected with multiple limiting arc strips.

[0015] The technical effect of adopting the above-mentioned further solution is that the limiting arc strip restricts multiple channels, and the sand and its minerals enter the interior of the feeding drum through the channels, preventing the sand and its minerals from damaging the inner shell of the feeding spoon box, and also preventing the sand and its minerals from clogging.

[0016] In a preferred embodiment, the inner wall of the feeding drum is provided with a groove, and the inside of the feeding drum is provided with a feeding chamber.

[0017] The technical effect of adopting the above-mentioned further solution is that the sand material and its minerals enter the feeding chamber from the inside of the trough and are fed into the ball mill.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In use, this utility model reduces the abrasive wear of the equipment by setting an alloy drill bit at the head of the spoon body. The two oblique grooves with an inner length of 10mm and a depth of 10mm in the oblique groove of the first wear-resistant area should be intersecting at the same angle. The iron plate material is selected as Q235 material, and materials with high carbon content should be avoided as much as possible to improve the welding strength and welding characteristics between the spoon body and the feeding spoon box. When the ore enters the feeding spoon box from the inside of the spoon body, its impact force is reduced by the buffer of the alloy drill bit.

[0020] 2. In use, the ore enters the interior of the feeding spoon box and is distributed within the inner cavity. The impact force strikes the outer surface of the baffle, causing the damper and spring to contract and buffer the baffle, thereby protecting the inner shell of the feeding spoon box. Under circular motion, a large amount of ore enters the interior of the feeding drum body from the slot for distribution, thereby reducing the wear of the feeding spoon box and the spoon head body and increasing its service life.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Please see Figures 1 to 4 This utility model provides a wear-resistant ball mill scoop head, comprising: a feeding drum body 101, two feeding scoop boxes 102 welded to the outer surface of the feeding drum body 101, connecting strips 103 welded to both outer surfaces of the two feeding scoop boxes 102, iron plates 107 welded to the other side of the two connecting strips 103, a scoop head body 104 welded to one side of the two iron plates 107, and multiple alloy drill bits 108 fixedly connected to opposite sides of the inner walls of the two iron plates 107. The rotation of the feeding drum body 101 drives the two feeding scoop boxes 102 to rotate circumferentially to dig ore. The iron plates 107 are fixed to both sides of the scoop head body 104 by the connecting strips 103. The scoop head body 104 is welded and fixed to the iron plates 107. The alloy drill bits 108 buffer the collision of ore entering the scoop head body 104, preventing the ore from damaging the inner surface of the scoop head body 104 and increasing the service life of the scoop head body 104.

[0030] like Figures 1 to 4 As shown, the inner walls of the two spoon bodies 104 are fixedly connected with fixing strips 105, and the outer surfaces of the two fixing strips 105 are fixedly connected with multiple alloy drill bits 106. The fixing strips 105 are welded to the alloy drill bits 106 through the spoon bodies 104. The impact of the return sand material and its ore blocks on the spoon bodies 104 is buffered by the alloy drill bits 106 to reduce the contact area with the spoon bodies 104, thereby increasing the service life of the spoon bodies 104.

[0031] like Figures 1 to 4 As shown, the inner surfaces of both spoon heads 104 are machined with oblique grooves 117 and 118. The oblique grooves 117 and 118 are machined and cut on the inner surfaces of the spoon heads 104 to form a wear-resistant area, thereby increasing the service life of the spoon head 104.

[0032] like Figures 1 to 4As shown, multiple connecting blocks 109 are fixedly connected to the top of the two feeding spoon boxes 102. The multiple connecting blocks 109 are welded to the outer surface of one side of the two iron plates 107. The top of the spoon head body 104 is connected through the connecting blocks 109 to prevent the top from shaking.

[0033] like Figures 1 to 4 As shown, the two feed spoon boxes 102 are provided with inner box cavities 110. The two connecting blocks 109 are each provided with two baffles 113. A damper 111 is fixedly connected to one side of each of the baffles 113. A spring 112 is sleeved on the outer surface of each of the dampers 111. When the return sand material and its ore blocks enter the inner box cavity 110, their impact force collides with the outer surface of the baffles 113. The impact force causes the dampers 111 and the springs 112 to contract and buffer the baffles 113, thereby protecting the inner shell of the feed spoon box 102.

[0034] like Figures 1 to 4 As shown, the inner walls of the two feeding spoon boxes 102 are fixedly connected with multiple limiting arc strips 114. The limiting arc strips 114 restrict multiple channels, and the sand and its minerals enter the interior of the feeding drum 101 through the channels, preventing the sand and its minerals from damaging the inner shell of the feeding spoon box 102 and preventing the sand and its minerals from clogging.

[0035] like Figures 1 to 4 As shown, the inner wall of the feeding drum 101 is provided with a groove 115, and the inside of the feeding drum 101 is provided with a feeding chamber 116. The sand and its minerals enter the inside of the feeding chamber 116 from the inside of the groove 115 and are fed into the inside of the ball mill.

[0036] The working principle of this utility model is as follows: During use, an alloy drill bit 106 is installed at the head of the spoon body 104 to reduce the erosion and wear of the equipment. The intersecting oblique grooves 118 of the two wear-resistant oblique grooves 117 should ensure that the intersection angles are consistent. The iron plate 107 is made of Q235 material, and materials with high carbon content should be avoided as much as possible to improve the welding strength and welding characteristics between the spoon body 104 and the feeding spoon box 102. When the ore enters the feeding spoon box 102 from the inside of the spoon body 104, its impact force is buffered by the alloy drill bit 108, reducing the damage to the spoon. The impact force between the head body 104 and the feeding spoon box 102 causes the ore to enter the interior of the feeding spoon box 102. The ore is distributed inside the inner box cavity 110. The impact force strikes the surface of the baffle 113, which causes the damper 111 and the spring 112 to contract and buffer the baffle 113, thereby protecting the inner shell of the feeding spoon box 102. Under the circumferential motion, a large amount of ore enters the interior of the feeding drum body 101 from the slot 115 for distribution, thereby reducing the wear of the feeding spoon box 102 and the spoon head body 104, thus increasing their service life.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
