Description

Technical Field

[0001] The present application relates to the technical field of steel ball casting, and in particular to a casting ball separator. Background Art

[0002] Wear-resistant cast balls, with their excellent wear and impact resistance, are important grinding media and are widely used in cement and mineral powder production. High-chromium alloy cast balls, with chromium as the primary alloying element, are the most common type of wear-resistant cast ball. Most domestic wear-resistant material companies utilize medium-frequency electric furnaces. They smelt a properly matched blend of high-quality scrap steel and chromium alloys, micro-alloy and temper the molten iron, and then utilize unique metal and sand mold casting processes. High-temperature quenching and tempering are then applied to obtain a martensitic matrix, achieving high hardness and wear resistance.

[0003] After casting, the wear-resistant cast balls are first added to the separation drum. The separation drum is cylindrical, axially through-the-tube, lined with a lining on the inner wall, and has an inlet at one end and an outlet at the other. The balls and risers are lifted to a certain height within the separation drum before falling, where they collide and rub against each other. This collision process separates the balls, risers, and waste sand, removing burrs and flash. Once all the balls are separated, the separation drum reverses, and the balls, risers, and waste sand are discharged along guide plates on the inner wall of the separation drum and fall into a vibrating sand shaker. The vibrating sand shaker removes the waste sand and collects the balls and risers into a sorting container. Workers then manually sort the balls and rod-shaped risers, which increases labor intensity and reduces production efficiency. Utility Model Content

[0005] The above-mentioned purpose of this application is achieved through the following technical solutions:

[0006] A cast ball separator comprises a sorting frame, wherein the upper and lower ends of the sorting frame are both provided with openings, and a plurality of mutually parallel screening rods are evenly provided in the lower end of the sorting frame, and the plurality of screening rods are arranged in the length direction of the lower end of the sorting frame;

[0007] The distance between two adjacent screening rods is between the diameter of the rod-shaped pouring head and the diameter of the casting ball;

[0008] The middle position of one opposite side of the sorting frame in the width direction is rotatably mounted on the support frame through a bracket, and a storage box is placed in the area below the sorting frame on the inner side of the support frame;

[0009] The outer side of one end of the sorting frame along the length direction of the screening rod is connected with a jacking mechanism, and the jacking mechanism can drive the sorting frame to swing up and down around the connection point between the sorting frame and the bracket.

[0010] Furthermore, the lifting mechanism includes a base frame provided on one side of the storage box, a column with a frame base is fixedly connected above the base frame near one side of the storage box, a drive shaft is provided at the upper end of the column along the width direction of the sorting frame, and the drive shaft is rotatably connected to the column;

[0011] One end of the drive shaft is fixedly connected to the center of the turntable, and the other end of the drive shaft is connected to the power output end of the reducer through a power transmission unit, and the power input end of the reducer is connected to the output end of the motor; the housings of the reducer and the motor are fixedly mounted on the top of the chassis;

[0012] A pin is fixedly provided on the edge of the turntable away from one end of the column, a driving rod is provided between the pin and the sorting frame, and the upper and lower ends of the driving rod are hinged to the sorting frame and the pin respectively.

[0013] Furthermore, two extension frames spaced apart from each other are fixedly provided in the middle area of the sorting frame near one end of the lifting mechanism, the upper end of the driving rod is located in the gap between the two extension frames away from one end of the sorting frame, and the driving rod and the two extension frames are hinged together by a connecting shaft.

[0014] Furthermore, the power transmission unit includes a first pulley connected to the drive shaft and a second pulley connected to the power output end of the reducer, and the first pulley and the second pulley are connected by a transmission belt.

[0015] Furthermore, a lifting cross bar is provided on one opposite side of the top of the support frame along the length direction, and a widening frame is provided on one opposite side of the top of the support frame along the width direction. A pad is fixed in the middle position of the widening frame, and the two brackets are respectively installed on the two pads.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] After the cast balls and risers to be screened are poured onto the sorting frame, they will fall on the multiple screening rods at the bottom of the sorting frame.

At this time, the jacking mechanism is started, and the jacking mechanism drives the sorting frame to swing up and down around the connection point between it and the bracket, so that the cast balls and rod-shaped pouring risers in the sorting frame will shake repeatedly along the axis of the screening rod. The position of the pouring riser will change during the shaking process. When its axis is parallel to the axis of the screening rod, it will automatically fall from the gap between the screening rods. After the jacking mechanism drives the sorting frame to shake continuously for a certain period of time, the screening rods can basically all fall into the storage box, and what remains in the sorting frame are all cast balls. Compared with the traditional manual sorting of cast balls and pouring risers, it not only improves the sorting efficiency but also reduces the labor intensity of workers.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0027] like Figures 1-4 As shown, a ball sorting machine disclosed in the present application includes a sorting frame 1, the upper and lower ends of the sorting frame 1 are provided with openings, and a plurality of mutually parallel screening rods 2 are evenly provided in the lower end of the sorting frame 1, and the plurality of screening rods 2 are arranged along the length direction of the lower end of the sorting frame 1; the distance between two adjacent screening rods 2 is between the diameter of the rod-shaped pouring riser and the diameter of the cast ball; the middle position of the opposite side of the width direction of the sorting frame 1 is rotatably mounted on the support frame 4 through a bracket 3, and a storage box 5 is placed in the area below the sorting frame 1 on the inner side of the support frame 4; a lifting mechanism 6 is connected to the outer side of one end of the sorting frame 1 along the length direction of the screening rod 2, and the lifting mechanism 6 can drive the sorting frame 1 to swing up and down around the connection point between it and the bracket 3.

[0028] In the above embodiment, the opening at the upper end of the sorting frame 1 facilitates the addition of materials such as cast balls to be screened, while the opening at the lower end of the sorting frame 1 provides a mounting base for the screening rod 2 and facilitates the discharge of materials screened by the screening rod 2 into the storage box 5 below. Opposite sides of the sorting frame 1 in the width direction are rotatably mounted on the support frame 4 via two brackets 3. In this way, when the lifting mechanism 6 drives the sorting frame 1 to swing at one end in the length direction, the material in the sorting frame 1 will move along the axis of the screening rod 2, thereby increasing the probability of rod-shaped casting risers in the material falling through the gaps in the screening rod 2.

[0029] like Figure 3 and Figure 4 As shown, after the cast balls and risers to be screened are poured onto the sorting frame 1, the cast balls and risers will fall onto the multiple screening rods 2 at the bottom of the sorting frame 1. Since the spacing between the screening rods 2 is larger than the diameter of the rod-shaped risers and smaller than the diameter of the cast balls, this ensures that the cast balls will never fall through the gaps between the screening rods 2. As long as the axis of the risers is parallel to the axis of the screening rods 2, they will automatically fall through the gaps between the screening rods 2. Therefore, after the initial addition, some of the rod-shaped risers will fall from the gaps between the screening rods 2 into the storage box 5 below, while other rod-shaped risers and cast balls that are at an angle to the screening rods 2 will remain above the screening rods 2.

[0030] At this time, the jacking mechanism 6 is started, and the jacking mechanism 6 drives the sorting frame 1 to swing up and down around the connection point between it and the bracket 3, so that the cast balls and rod-shaped pouring risers in the sorting frame 1 will shake repeatedly along the axis direction of the screening rod 2. The position of the pouring riser will change during the shaking process. When its axis is parallel to the axis of the screening rod 2, it will automatically fall from the gap between the screening rods 2. After the jacking mechanism 6 drives the sorting frame 1 to shake continuously for a certain period of time, the pouring risers can basically all fall into the storage box 5, and what remains in the sorting frame 1 are all cast balls. Compared with the traditional method of manual sorting of cast balls and pouring risers, the present application not only improves the sorting efficiency, but also reduces the labor intensity of workers, and also reduces the labor cost of the enterprise to a certain extent.

[0031] Some companies use one pouring head to cast multiple cast balls at the same time during production. This will result in the cast balls having many runners in addition to the pouring head after production, and the diameter of the runner is usually smaller than the pouring head. Therefore, when the selection box 1 of this application screens the cast balls and pouring heads, it will also screen the pouring heads and runners into the storage box 5.

[0032] Furthermore, if Figure 1 As shown, the lifting mechanism 6 includes a base frame 61 provided on one side of the storage box 5. A column 62 with a frame base 63 is fixedly connected to the upper side of the base frame 61 near the storage box 5. A drive shaft 64 is provided at the upper end of the column 62 along the width direction of the sorting frame 1, and the drive shaft 64 is rotatably connected to the column 62.

[0033] One end of the drive shaft 64 is fixedly connected to the center of the turntable 65, and the other end of the drive shaft 64 is connected to the power output end of the reducer 67 through the power transmission unit 66. The power input end of the reducer 67 is connected to the output end of the motor 68. The housings of the reducer 67 and the motor 68 are fixedly mounted on the top of the base frame 61.

[0034] A pin 69 is fixedly provided on the edge of the turntable 65 away from the column 62. A driving rod 610 is provided between the pin 69 and the sorting frame 1. The upper and lower ends of the driving rod 610 are hinged to the sorting frame 1 and the pin 69 respectively.

[0035] In the above embodiment, a pin 69 located on the edge of the turntable 65 of the present application is movably connected to the sorting frame 1 via a drive rod 610 in the above-described manner. Furthermore, the sorting frame 1 itself is rotatably connected to the bracket 3 mounted on the support frame 4. Thus, when the turntable 65 rotates around the center of the drive shaft 64, it, together with the drive rod 610 and the sorting frame 1, forms a structure similar to a crank rocker mechanism, thereby causing the sorting frame 1 to swing up and down around its rotational connection point with the bracket 3, achieving a shaking effect. The motor 68, through the reducer 67 and the power transmission unit 66, can continuously provide power to the drive shaft 64, causing the drive shaft 64 to rotate continuously, and the sorting frame 1 achieves an automatic screening effect, effectively improving screening efficiency. Furthermore, during use, workers only need to control the start and stop of the motor 68, making operation very convenient.

[0036] Furthermore, if Figure 1 and Figure 2 As shown, two extension frames 7 spaced apart from each other are fixedly provided in the middle area of the sorting frame 1 near one end of the lifting mechanism 6, the upper end of the driving rod 610 is located in the gap between the two extension frames 7 away from one end of the sorting frame 1, and the driving rod 610 and the two extension frames 7 are hinged together by a connecting shaft 8.

[0037] In the above embodiment, the extension frame 7 provided at the end of the sorting frame 1 in the above manner can increase the distance between the driving rod 610 and the sorting frame 1 when rotating with the turntable 65, thereby reducing the risk of interference between the driving rod 610 and the upper end of the support frame 4 during operation.

[0038] Furthermore, if Figure 1 and Figure 2 As shown, the power transmission unit 66 includes a first pulley 661 connected to the drive shaft 64 and a second pulley 662 connected to the power output end of the reducer 67. The first pulley 661 and the second pulley 662 are connected by a transmission belt 663.

[0039] Compared to the sprocket and chain transmission in the above embodiment, the transmission between the drive shaft 64 and the power output end of the reducer 67 in the present application is transmitted via the first pulley 661, the second pulley 662, and the transmission belt 663 therebetween. This not only reduces noise during operation but also reduces maintenance costs. Furthermore, the production site for cast balls inevitably contains some dust. The transmission method employed in this application is less susceptible to dust than the sprocket and chain operation process, and the overall stability of the equipment during operation is also ensured.

[0040] Furthermore, if Figure 1 and Figure 3As shown, a lifting cross bar 9 is provided on one opposite side of the top of the support frame 4 along the length direction, and a widening frame 10 is provided on one opposite side of the top of the support frame 4 along the width direction. A pad 11 is fixed in the middle position of the widening frame 10, and the two brackets 3 are respectively installed on the two pads 11.

[0041] In the above embodiment, the two lifting bars 9 provided on the support frame 4 can provide a position limit protection for the sorting frame 1, preventing the sorting frame 1 from accidentally tipping over. At the same time, after screening, one end of the sorting frame 1 can be tilted onto the lifting bar 9 on the corresponding side by the jacking mechanism 6, so that all the cast balls in the sorting frame 1 are gathered together, making it easier for workers to collect them. The two widening frames 10 in the width direction of the support frame 4 can provide a mounting base for the two brackets 3 through the support frame 4. The pads 11 on the widening frames 10 can increase the contact area between them and the lower ends of the brackets 3, thereby ensuring the support effect of the brackets 3 on the sorting frame 1.

[0042] Furthermore, if Figure 1 As shown, a dust curtain 12 is installed on the peripheral side of the support frame 4.

[0043] In the above embodiment, when the sorting machine of the present application is in operation, the pouring riser falls from the sorting frame 1 into the storage box 5, which inevitably generates some dust. This dust may not only affect nearby equipment and workers, but also increase the burden of subsequent cleaning. Therefore, the present application installs a dust curtain 12 on the side of the support frame 4 to seal the dust inside the support frame 4, thereby reducing the negative impact of these dusts on nearby equipment and workers, and the workload of subsequent cleaning around the corresponding equipment will also be reduced.

[0044] Furthermore, if Figure 1 and 3 As shown, a plurality of comb teeth 13 are evenly provided on the upper sides of the plurality of screening rods 2, and the comb teeth 13 on adjacent screening rods 2 are staggered with each other.

[0045] In the above embodiment, the comb teeth 13 arranged on the screening rod 2 in the above manner can increase the frequency of the position change of the pouring and riser when the selection frame 1 swings, thereby increasing the probability that the axes of these pouring and riser tend to be parallel to the axis of the screening rod 2, which can improve the screening efficiency to a certain extent.

[0046] The implementation principle of this embodiment is: when in use, after the materials such as cast balls and pouring risers to be screened are poured onto the sorting frame 1, the cast balls and pouring risers will fall on the multiple screening rods 2 at the bottom of the sorting frame 1. Since the spacing between the screening rods 2 is larger than the diameter of the rod-shaped pouring risers and smaller than the diameter of the cast balls, at this time, some of the rod-shaped pouring risers parallel to the axis of the screening rods 2 will first fall from the gaps between the screening rods 2 into the storage box 5 below, and other pouring risers and cast balls that have a large angle with the screening rods 2 will remain above the screening rods 2.

[0047] Next, the motor 68 of the lifting mechanism 6 is started. The motor 68 drives the drive shaft 64 to rotate through the reducer 67. The drive shaft 64 rotates with the turntable 65. At this time, the drive rod 610 connected to the turntable 65 will drive the sorting frame 1 to swing up and down around its connection point with the bracket 3. The cast balls and rod-shaped pouring risers in the sorting frame 1 will shake repeatedly along the axis of the screening rod 2. The position of the pouring risers will change during the shaking process. The multiple comb teeth 13 on the screening rod 2 can exacerbate this change. As long as the axis of the pouring risers becomes parallel to the axis of the screening rod 2, they will automatically fall from the gap between the screening rods 2. After the lifting mechanism 6 drives the sorting frame 1 to shake continuously for a certain period of time, the screening rods 2 can basically all fall into the storage box 5, and the remaining in the sorting frame 1 is all cast balls. Compared with the traditional manual sorting of cast balls and pouring risers, not only the sorting efficiency is improved, but also the labor intensity of the workers is reduced.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
