Technical Field

[0001] This invention belongs to the field of cylinder liner casting feeding, specifically relating to a push-type feeding device for cylinder liner casting. Background Technology

[0002] The push-feed device for cylinder liner casting pushes the metal powder raw material of the cylinder liner into the furnace. The metal powder raw material is completely melted into liquid and then poured into the mold to solidify and form a solid shape, providing a reliable technical guarantee for continuous, stable and high-quality casting of cylinder liners.

[0003] Patent CN207577356U discloses a push-type feeding device for cylinder liner casting, including a bracket, a feed hopper and a discharge port mounted on the bracket, a feeding channel between the feed hopper and the discharge port, a control cylinder mounted on the bracket, and a push-through hole connected to the feeding channel on the bracket, the push-through hole being located at one end of the feed hopper. A push plate is mounted on the bottom wall of the feeding channel, the push plate being fixed to the piston shaft of the control cylinder. An inclined arc-shaped push plate is uniformly and integrally formed on the top surface of the push plate, with the inclined opening of the arc-shaped push plate located on the discharge port side. Under the action of the control cylinder, the arc-shaped push plate pushes the raw material at the feed hopper toward the discharge port. The structure of this patent is reasonably designed, and different conveying angles can be adjusted as needed, thereby greatly improving its applicability, ensuring the reliability of conveying, improving processing efficiency to a certain extent, having good stability in use, strong applicability, and good practicality.

[0004] When the feeding device is conveying the metal powder raw material for cylinder liner casting, the metal powder raw material will accumulate at the powder inlet of the conveying pipe, which will lead to poor conveying effect of the feeding device. At the same time, the metal powder raw material for cylinder liner casting is damp and clumps together, which is not conducive to the feeding device, thus leading to poor conveying effect of the feeding device. Furthermore, the damp metal powder raw material for cylinder liner casting will stick to the hopper, which will lead to the feeding device being prone to aging and rusting. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The present invention uses a bottom frame, hopper, conveying pipe, spiral blade, square shell, round pipe, motor, transmission assembly, round rod, U-shaped ring frame and short column in conjunction with chamfered frame. The output shaft of the motor drives the transmission assembly to rotate forward, the transmission assembly drives the spiral blade to rotate forward, the raw material falls down from the powder inlet, the spiral blade conveys the raw material to the right during the rotation, the raw material falls down from the outlet for melting, the transmission assembly drives the round rod to rotate forward, the round rod drives the U-shaped ring frame to rotate forward, the U-shaped ring frame drives the short column to rotate forward, the short column drives the chamfered frame to rotate forward, the chamfered frame pushes the raw material to the powder inlet during the rotation, preventing the metal powder raw material from accumulating at the powder inlet of the conveying pipe, which would cause the feeding device to have poor conveying effect of cylinder liner casting metal powder.

[0018] (2) By setting up a separating device, the present invention enables the U-shaped rod, the tube block and the loop frame to work with the metal mesh. The U-shaped ring frame drives the U-shaped rod to rotate forward, the U-shaped rod drives the tube block to rotate forward, the tube block drives the loop frame to rotate forward, and the loop frame drives the metal mesh to rotate forward.

The bottom right side of the conveying pipe 3 has an outlet, and the top surface of the conveying pipe 3 has a powder inlet. The powder inlet of the conveying pipe 3 passes through and is fixed in the middle of the bottom surface of the hopper 2. The conveying pipe 3 is located below the hopper 2. The spiral blade 4 is installed through and rotatably on the left and right sides of the inner wall of the conveying pipe 3; Square shell 5, square shell 5 is fixed on the left side of hopper 2; A circular tube 6 is inserted and fixed to the lower left side of the square shell 5. The right end of the circular tube 6 is fixedly connected to the left end of the conveying pipe 3. A groove is opened on the top surface of the circular tube 6. Motor 7 is fixed on the left side of the top surface of the bottom frame 1, and the right side of motor 7 is fixedly connected to the left end of the round tube 6. The transmission assembly 8 is located above the inner wall of the square shell 5 and is situated in the middle of the interior of the square shell 5. The transmission assembly 8 includes: an I-shaped shaft disc 801, an I-shaped disc 802, a belt 803, and a long shaft 804. The I-shaped shaft disc 801 is rotatably mounted on the left end of the round rod 9, and the right end of the I-shaped shaft disc 801 is rotatably connected to the right side of the inner wall of the square shell 5. The I-shaped disc 802 is fixed to the left end of the spiral blade rod 4. The belt 803 is rotatably mounted on the inner walls of the I-shaped shaft disc 801 and the I-shaped disc 802 and is located inside the groove of the round tube 6. The long shaft 804 is fixed to the middle of the left side of the I-shaped disc 802, and the left end of the long shaft 804 is fixedly connected to the right end of the output shaft of the motor 7. A round rod 9 is installed through and rotatably on the left and right sides of the inner wall of the hopper 2, and the round rod 9 is located in the middle of the inside of the hopper 2; Two U-shaped ring frames 10 are fixed to the outer wall of the round rod 9, and four round holes are opened on the outer wall of each of the two U-shaped ring frames 10. Four short columns 11 are connected and fixed to the outer walls of two U-shaped ring frames 10 in pairs. Two chamfered frames 12 are fixed to the ends of the four short columns 11 that are far apart from each other. The two chamfered frames 12 are triangular in shape. The outer walls of the two chamfered frames 12 slide in contact with the bottom of the inner side of the square shell 5. The two chamfered frames 12 are used to push the cylinder liner casting metal powder into the conveying pipe 3. When using this push-type feeding device, the operator feeds the cylinder liner casting metal powder raw material into the hopper 2. The operator starts the motor 7 on the bottom frame 1. The output shaft of the motor 7 starts to rotate forward, which drives the long shaft 804 of the transmission component 8 to rotate forward. The long shaft 804 drives the I-shaped disk 802 to rotate forward. The I-shaped disk 802 rotates in the circular tube 6, which drives the spiral blade 4 to rotate forward. The spiral blade 4 rotates forward in the conveying pipe 3. The cylinder liner casting metal powder raw material falls downward from the powder inlet of the conveying pipe 3 and falls onto the spiral blade 4. During the rotation, the spiral blade 4 conveys the cylinder liner casting metal powder raw material to the right. The metal powder raw material falls downward from the outlet of the conveying pipe 3 to be melted. At the same time, the I-shaped disc 802 drives the belt 803 to rotate forward. The belt 803 rotates forward in the square shell 5, drives the I-shaped shaft disc 801 to rotate forward, the I-shaped shaft disc 801 drives the round rod 9 to rotate forward, the round rod 9 drives the U-shaped ring frame 10 to rotate forward, the U-shaped ring frame 10 drives the short column 11 to rotate forward, and the short column 11 drives the chamfered frame 12 to rotate forward. During the rotation, the chamfered frame 12 pushes the cylinder liner casting metal powder raw material to the powder inlet of the conveying pipe 3, thereby avoiding the problem that the metal powder raw material will accumulate at the powder inlet of the conveying pipe 3 during the use of the feeding device, which would cause the feeding device to have poor conveying effect of cylinder liner casting metal powder. The inner wall of the U-shaped ring frame 10 is provided with a separating device 13, which is used to separate the agglomerated cylinder liner casting metal powder. The outer wall of the separating device 13 is provided with a drying device 14, which is used to heat and dry the cylinder liner casting metal powder.

[0034] Working principle: Raw materials are fed into hopper 2. The output shaft of motor 7 drives long shaft 804 to rotate forward, long shaft 804 drives I-shaped disc 802 to rotate forward, I-shaped disc 802 drives spiral blade 4 to rotate forward, spiral blade 4 rotates forward in conveying pipe 3, raw materials fall downward from the powder inlet, spiral blade 4 conveys raw materials to the right during rotation, raw materials fall downward from the outlet for melting, I-shaped disc 802 drives belt 803 to rotate forward, belt 803 drives I-shaped shaft disc 801 to rotate forward, I-shaped shaft disc 801 drives round rod 9 to rotate forward, round rod 9 drives U-shaped ring frame 10 to rotate forward, U-shaped ring frame 10 drives short column 11 to rotate forward, short column 11 drives chamfered frame 12 to rotate forward, chamfered frame 12 pushes cylinder liner casting metal powder raw materials to the powder inlet during rotation.

[0035] like Figure 1-8 As shown, based on the above embodiments, in another embodiment of the present invention, the separating device 13 includes: four U-shaped rods 131, which are respectively fixed to the inner walls of the circular holes of the two U-shaped ring frames 10; Pipe block 132, pipe block 132 is fixed to the outer wall of four U-shaped rods 131 respectively; Two loop frames 133 are fixed on the outer wall of the four tube blocks 132, and the two loop frames 133 are located inside the U-shaped ring frame 10; Metal mesh 134 is fixed to the inner walls of the two loop frames 133 respectively; Metal mesh 134 is used to separate clumped cylinder liner casting metal powder; While the U-shaped ring frame 10 drives the short column 11 to rotate forward, the U-shaped ring frame 10 drives the U-shaped rod 131 to rotate forward, the U-shaped rod 131 drives the tube block 132 to rotate forward, the tube block 132 drives the loop frame 133 to rotate forward, and the loop frame 133 drives the metal mesh 134 to rotate forward. During the rotation, the metal mesh 134 separates the clumps of cylinder liner casting metal powder raw materials, thereby avoiding the problem of poor conveying effect of the feeding device caused by the damp clumping of cylinder liner casting metal powder raw materials during use.

[0036] Each of the four U-shaped rods 131 has a vertical shell 135 fixed at both ends. A spring 136 is fixed at the top and bottom of the four vertical shells 135. A square plate 137 is provided at the end of each spring 136 away from the vertical shell 135. A counterweight ball 138 is provided inside each of the four vertical shells 135. While the U-shaped rod 131 drives the tube block 132 to rotate clockwise, the U-shaped rod 131 drives the vertical shell 135 to rotate clockwise, the vertical shell 135 drives the spring 136 to rotate clockwise, and the spring 136 drives the square plate 137 to rotate clockwise. At the same time, during the rotation of the vertical shell 135, the counterweight ball 138 will roll downward in the vertical shell 135 and hit the square plate 137, causing the square plate 137 to vibrate. The square plate 137 transmits the vibration to the spring 136, the spring 136 transmits the vibration to the vertical shell 135, the vertical shell 135 transmits the vibration to the U-shaped rod 131, and the U-shaped rod 131 transmits the vibration to the U-shaped ring frame 10, causing the chamfered frame 12 to rotate and vibrate to push the material. This avoids the problem that the agglomerated cylinder liner casting metal powder raw material is not easy to disperse during the use of the feeding device, resulting in poor feeding effect of the feeding device.

[0037] The drying device 14 includes: two racks 141, which are fixed to the outer walls of four vertical shells 135; Strip shell 142, which penetrates and is fixed to the outer wall of the two frame plates 141; Resistance heating rod 143 is fixedly installed on the inner wall of strip shell 142; Copper plate 144 is fixed to the inner wall of the two strip shells 142 respectively; The copper plate 144 dries the cylinder liner casting metal powder in the hopper 2 during the rotation process. While the vertical shell 135 drives the spring 136 to rotate clockwise, the vertical shell 135 drives the frame plate 141 to rotate clockwise, the frame plate 141 drives the strip shell 142 to rotate clockwise, the strip shell 142 drives the resistance heating rod 143 to rotate clockwise, and the strip shell 142 drives the copper plate 144 to rotate clockwise. The operator starts the resistance heating rod 143, and the resistance heating rod 143 begins to heat up. The resistance heating rod 143 transfers heat to the copper plate 144, so that the copper plate 144 heats the cylinder liner casting metal powder raw material during the rotation. This avoids the problem that the damp cylinder liner casting metal powder raw material will stick to the hopper 2 during the use of the feeding device, causing the feeding device to age and rust easily.

[0038] Two recessed blocks 145 are fixed to the outer walls of the two frame plates 141 respectively, and an arc rod 146 is fixed to the inner wall of each of the four recessed blocks 145. A connecting block 147 is fixed to one end of each of the four arc rods 146 that is close to each other. The outer walls of the four connecting blocks 147 are fixedly connected to the outer wall of the loop frame 133. While the strip shell 142 drives the resistance heating rod 143 to rotate forward, the strip shell 142 drives the concave block 145 to rotate forward, the concave block 145 drives the arc rod 146 to rotate forward, the arc rod 146 drives the connecting block 147 to rotate forward, and the connecting block 147 supports the rotation of the loop frame 133, thereby avoiding the problem of poor separation effect of the metal mesh 134 caused by the rotation and deformation of the loop frame 133 during the use of the feeding device.

[0039] Working principle: The U-shaped ring frame 10 drives the U-shaped rod 131 to rotate forward, the U-shaped rod 131 drives the tube block 132 to rotate forward, the tube block 132 drives the spiral frame 133 to rotate forward, the spiral frame 133 drives the metal mesh 134 to rotate forward, and the metal mesh 134 separates the agglomerated cylinder liner casting metal powder raw materials. U-shaped rod 131 drives vertical shell 135 to rotate clockwise, vertical shell 135 drives spring 136 to rotate clockwise, spring 136 drives square plate 137 to rotate clockwise, counterweight ball 138 rolls downward in vertical shell 135, counterweight ball 138 will hit square plate 137, square plate 137 will vibrate, vertical shell 135 transmits vibration to U-shaped rod 131, U-shaped rod 131 transmits vibration to U-shaped ring frame 10; The vertical shell 135 drives the frame plate 141 to rotate forward, the frame plate 141 drives the strip shell 142 to rotate forward, the strip shell 142 drives the resistance heating rod 143 to rotate forward, the strip shell 142 drives the copper plate 144 to rotate forward, and the resistance heating rod 143 transfers heat to the copper plate 144, so that the copper plate 144 heats the cylinder liner casting metal powder raw material during the rotation.
