A crushing block 8 is provided at the lower end of the hydraulic push rod 5, and the crushing block 8 is used to crush the metal smelting ore. A bottom plate 11 is provided in the main body 16 below the feed port 3. The upper surface of the bottom plate 11 is funnel-shaped, that is, the middle bottom of the upper surface of the bottom plate 11 is high around. The metal smelting material is added from the feed port 3 and falls onto the upper surface of the bottom plate 11. Under the action of gravity, the smelting material approaches the center of the bottom plate 11. A receiving chamber 15 is provided in the main body 16 below the bottom plate 11. The lower part of the receiving chamber 15 is also funnel-shaped. A driving block 9 is provided below the crushing block 8. The driving block 9 penetrates and is slidably connected to the center of the bottom plate 11, and a plurality of grooves 902 are circumferentially distributed on the side of the driving block 9. Preferably, the grooves 902 The cross-sectional shape is semicircular, and a limit block 18 is fixedly connected to the accommodating chamber 15 in the main body 16, which limits the driving block 9. When the driving block 9 moves downward to the bottom, it is blocked and limited by the limit block 18. A connecting chamber 12 is also provided below the driving block 9, and a connecting rod 14 is rotatably connected in the limit block 18. The connecting rod 14 passes through the limit block 18 and can be rotatably connected in the limit block 18 through a bearing. The upper end of the connecting rod 14 passes through the connecting chamber 12 and is fixedly connected to a top block 13. The top block 13 has a one-way driving mechanism, and a spiral slide rail 121 is provided in the connecting chamber 12. The spiral slide rail 121 moves along the connecting chamber. 12 is extended to the inner surface, the one-way driving mechanism is slidably connected to the spiral slide rail 121, the lower end of the connecting rod 14 passes through the main body 16 and is provided with a spiral blade 17, the side of the spiral blade 17 is in contact with the main body 16, and the hydraulic push rod 5 is started to drive the crushing block 8 to move downward to crush the metal ore on the chassis 11. When the crushing block 8 moves upward, the groove 902 on the driving block 9 opens upward, so that the metal ore of suitable size enters the accommodating chamber 15 from the groove 902 downward, and then enters the smelting furnace 1 for smelting under the drive of the spiral blade 17.

[0032] Among them, as attached Figure 3 As shown, as a preferred way of forming the groove shape, the cross-sectional area of ​​the groove 902 gradually increases from top to bottom. By increasing the cross-sectional area of ​​the groove 902 from top to bottom, the distance of the hydraulic push rod 5 moving up and down can be adjusted, so that the opening formed by the groove 902 and the chassis 11 becomes adjustable, and the size of the crushed metal ore can be adjusted and screened, so as to better cooperate with the smelting work of the smelting furnace 1.

[0033] Among them, as attached Figure 2-3As shown, the chassis 11 is slidably connected to the main body 16, and a plurality of positioning bars 903 are circumferentially provided on the side of the driving block 9. Four positioning bars 903 can be provided, which are embedded in the chassis 11, and a plurality of retaining springs 904 are provided on the positioning bars 903.

When the driving block 9 moves upward, the retaining springs 904 exert an upward force on the chassis, thereby driving the chassis 11 to slide upward. After the retaining springs 904 are compressed, the chassis 11 falls. The plurality of retaining springs 904 drive the chassis 11 to vibrate, thereby driving the metal ore on the chassis 11 to vibrate toward the center, so that the metal ore of qualified size on the chassis 11 is screened and falls by the grooves 902.

[0035] Among them, as attached Figure 4 As shown, a soft filler 905 is fixed in the retaining spring 904 to block the gap. The filler 905 can be bonded inside the retaining spring 904 to prevent metal ore materials from entering the middle of the retaining spring 904 and jamming the retaining spring 904.

When the driving block 9 moves downward, it drives the connecting chamber 12 to move downward, and then drives the slider 141 to slide on the spiral slide rail 121. The spiral slide rail 121 applies a force to the flat surface on the slider 141, and the top block 13 rotates. When the connecting chamber 12 moves upward, the spiral slide rail 121 applies a force to the inclined surface on the slider 141, so that the slider 141 retracts inward, the slider 141 is disengaged from the spiral slide rail 121, and the top block 13 does not rotate. In this way, the top block 13 can rotate in one direction.

[0037] Among them, the unidirectional driving mechanism includes a pawl 142, and a resettable pawl 142 is hinged in the top block 13. The pawl 142 can realize the reset function by providing a torsion spring. The outer end of the pawl 142 is slidably connected in the spiral slide rail 121. When the driving block 9 moves downward, it drives the connecting chamber 12 to move downward, and then drives the pawl 142 to slide on the spiral slide rail 121, and then drives the top block 13 to rotate. When the connecting chamber 12 moves upward, the spiral slide rail 121 applies force to the pawl 142, so that the pawl 142 rotates inward and retracts, the pawl 142 disengages from the spiral slide rail 121, and the top block 13 does not rotate. In this way, the top block 13 can rotate in one direction.

[0038] Among them, the lower end of the hydraulic push rod 5 is rotatably connected to a rotating shaft 6, the lower end of the rotating shaft 6 is fixedly connected to a connecting block 7, a crushing block 8 is slidably connected to the connecting block 7, the crushing block 8 is restricted by the connecting block 7 in the cross-sectional direction and cannot rotate, the driving block 9 passes through the crushing block 8 and is connected to the connecting block 7, a protrusion 701 is provided in the connecting block 7, an arc track 901 is opened on the side surface of the driving block 9, the protrusion 701 is slidably connected to the arc track 901, and the driving block 9 and the connecting block 7 are also connected by a spring 10.

[0044] Working principle:

[0045] The metal ore is added to the chassis 11 through the feed port 3, and the hydraulic push rod 5 is started, thereby driving the connecting block 7 to move downward, and then driving the crushing block 8 to move downward, so that the bottom of the crushing block 8 contacts the metal ore on the chassis 11 to knock and crush it, and the hydraulic push rod 5 continues to move downward, and the driving block 9 moves downward and is limited by the limit block 18, so that the spring 10 is compressed, and then drives the protrusion 701 on the connecting block 7 to slide on the arc track 901, and then drives the connecting block 7 to rotate, and then drives the crushing block 8 to rotate to grind and crush the metal ore on the chassis 11, so that the crushing effect of the metal ore is better, and drives the hydraulic push rod 5 to move upward, and then drives the connecting block 7 to reset under the action of the spring 10, and then drives the connecting block 7 to separate from the metal ore and move upward, and pulls the driving block 9 at the same time.

When the driving block 9 moves downward, it drives the connecting chamber 12 to move downward, and then drives the top block 13 to rotate under the action of the spiral slide rail 121, and then drives the connecting rod 14 to rotate, and then drives the spiral blade 17 to rotate, and then drives the metal ore in the accommodating chamber 15 to move downward along the spiral blade 17 and fall into the smelting furnace 1. When the spiral blade 17 stops, the feeding mechanism 2 does not unload the material. When the frequency of the hydraulic push rod 5 moving up and down is accelerated, the feeding rate of the spiral blade 17 is accelerated, thereby realizing the control of the feeding rate. After the metal ore enters the smelting furnace 1, metal smelting begins.
