At the same time, when the rubber plate descends, it will also drive the damping block to descend. Due to the descent of the damping block, the telescopic rod and the second spring will be squeezed, causing the second spring to deform. At the same time, when the first spring and the second spring rebound, through the action of the telescopic rod and the sliding rod, the first spring and the second spring will not swing significantly during the rebound, thus ensuring the achievement of the buffering purpose;

[0021] 2. By setting up a drive motor, a rotating rod, stirring blades, connecting rods and a pushing plate, after the wear-resistant balls fall to the bottom of the main body, by starting the drive motor, the drive motor can drive the rotation of the rotating rod. Through the rotation of the rotating rod, the rotation of the stirring blades can be driven. Through the rotation of the stirring blades, the rotation of the connecting rods and the pushing plate can be driven.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution: a semi-finished product calcination kiln for wear-resistant ball production, including a main body 1. An inlet 2 is provided on one side surface of the top of the main body 1; an extension plate 3 is fixedly connected to one side surface of the main body 1 near the top. A driving motor 4 is fixedly installed on the top surface of the extension plate 3. The output end of the driving motor 4 passes through one side surface of the main body 1 and is fixedly connected to a rotating rod 5. A plurality of stirring blades 6 are symmetrically installed on the side surface of the rotating rod 5 away from the driving motor 4. A connecting rod 7 is fixedly connected to the surface of the stirring blade 6. A plurality of pushing plates 8 are symmetrically installed on the surface of the connecting rod 7. The rotating rod 5 is rotatably connected to the main body 1. A support frame 9 is symmetrically installed inside the main body 1. A connecting plate 10 is fixedly connected to the top surface of the support frame 9. A groove 17 is provided inside the connecting plate 10; further included: a buffer assembly 18 is provided inside the groove 17; wherein, the buffer assembly 18 includes a fixed block 1801 fixedly connected to the groove 17. A sliding rod 1802 is fixedly connected to one side surface of the fixed block 1801. Two sides of the surface of the sliding rod 1802 are slidably connected with damping sleeves 1803; wherein, a first spring 1804 is fixedly connected to one side surface of the damping sleeve 1803. The first spring 1804 is sleeved on the sliding rod 1802. As Figure 1 , 2 , as shown in Figures 4, by setting the buffer assembly 18, it is possible to buffer the wear-resistant balls after they enter the main body 1, thereby reducing damage to the main body 1, the stirring blades 6, and the pushing plates 8 caused by the wear-resistant balls. At the same time, a heating plate is installed inside the main body 1. A calcination chamber is provided inside the main body 11. The heating plate is located outside the calcination chamber, so as to facilitate high-temperature calcination of the wear-resistant balls inside the calcination chamber. At the same time, the rotating rod 5, the stirring blades 6, the connecting rod 7, and the pushing rod 8 are all made of silicon carbide and have good high-temperature resistance, so that they will not be damaged due to the high-temperature treatment of the wear-resistant balls.

[0031] The top surface of the damping sleeve 1803 is rotatably connected to a movable rod 1805. The top surface of the movable rod 1805 is rotatably connected to a rubber plate 1806. On both sides of the top surface of the rubber plate 1806, damping blocks 1807 are symmetrically installed. The bottom surface of the damping block 1807 is fixedly connected to a telescopic rod 1808. A second spring 1809 is sleeved on the surface of the telescopic rod 1808. The bottom surface of the second spring 1809 is fixedly connected to the fixed block 1801. The top surface of the second spring 1809 is fixedly connected to the rubber plate 1806. The bottom surface of the telescopic rod 1808 is fixedly connected to the fixed block 1801, as Figure 4 shown. When the rubber plate 1806 is squeezed and descends, it will squeeze the movable rod 1805, thereby causing the movable rod 1805 to move. Through the movement of the movable rod 1805, the damping sleeve 1803 will be pushed, so that the damping sleeve 1803 will slide on the sliding rod 1802, thereby causing the damping sleeve 1803 to squeeze the first spring 1804, causing the first spring 1804 to deform. At the same time, when the rubber plate 1806 descends, it will also drive the damping block 1807 to descend. Through the descent of the damping block 1807, the telescopic rod 1808 and the second spring 1809 will be squeezed, causing the second spring 1809 to deform. At the same time, when the first spring 1804 and the second spring 1809 rebound, through the action of the telescopic rod 1808 and the sliding rod 1802, the first spring 1804 and the second spring 1809 will not swing significantly when rebounding, thus ensuring the purpose of buffering. After the wear-resistant ball falls to the bottom of the body 1, it will not damage the stirring blade 6 and the pushing plate 8. At the same time, the first spring 1704 and the second spring 1809 are rubber composite springs in the prior art.

[0032] A chute 11 is opened in the middle of the bottom surface of the body 1. A slider 12 is slidably connected inside the chute 11. The top surface of the slider 12 is fixedly connected to a cooling box 13, as Figure 1 shown, which facilitates the extraction of the cooling box 13.

[0033] A sliding rod 14 is fixedly installed above the cooling box 13. A toothed plate 15 is slidably connected to the surface of the sliding rod 14. The surface of the toothed plate 15 penetrates through a limit box 16. The top surface of the limit box 16 is fixedly connected to the body 1, as Figure 1 shown. The limit box 16 is penetrated by the sliding rod 14. The toothed plate 14 is slidably penetrated through the limit box 16. At the same time, the limit box 16 is fixedly connected to the periphery of the calcination chamber.

[0034] One side of the bottom surface of the toothed plate 15 is meshed and connected with a gear 19. A rotating rod 20 is connected through the middle of the surface of the gear 19. The rotating rod 20 is rotatably connected with the limiting box 16. One side surface of the main body 1 near the bottom is fixedly connected with a support plate 21. One side surface of the top of the support plate 21 far away from the main body 1 is fixedly installed with an extension block 22. A limiting rod 23 is connected through one side surface of the extension block 22 near the top. A third spring 24 is sleeved on one side surface of the limiting rod 23. One side surface of the third spring 24 is fixedly connected with a fitting plate 25. The other side surface of the third spring 24 is fixedly connected with a damping block 1807. One side surface of the fitting plate 25 far away from the third spring 24 is in fitting connection with the rotating rod 20. The limiting rod 23 is connected through the fitting plate 25. A plurality of limiting grooves 26 are symmetrically arranged on one side surface of the rotating rod 5 far away from the limiting box 16 and passing through the main body 1. The limiting grooves 26 are in clamping connection with the limiting rod 23. As Figure 1 、 2 、3, 5, and 6 show that by pulling the limiting rod 23, after the limiting rod 23 is separated from the limiting groove 26, by rotating the rotating rod 20, the rotating rod 20 can drive the rotation of the gear 19. By the rotation of the gear 19, the toothed plate 15 can be driven to move on the sliding rod 14, so that the toothed plate 15 no longer blocks the hole, so that the wear-resistant balls fall into the cooling box 13 for cooling. At the same time, after the wear-resistant balls are cooled, by opening the door on the main body 1 and then pulling out the cooling box 13, the wear-resistant balls can be collected, thus completing the calcination operation of the wear-resistant balls. At the same time, a hole is opened in the middle of the bottom of the calcination chamber. The toothed plate 15 can open and close the hole. At the same time, the two sides near the bottom of the calcination chamber are inclined surfaces, so that no wear-resistant balls will accumulate inside the calcination chamber

[0035] The top surface of the rubber plate 1806 is fixedly connected with a buffer plate 27. The buffer plate 27 is slidably connected with the groove 17. As Figure 1 、 4 shown, the buffer plate 27 can buffer the wear-resistant balls.

[0036] Working principle: Before using this semi-finished product calcination kiln for the production of wear-resistant balls, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 6As shown, first, the wear-resistant balls are poured into the interior of the main body 1 through the feed inlet 2. As a result, the wear-resistant balls will fall onto the buffer plate 27, causing the buffer plate 27 to descend. Due to the descent of the buffer plate 27, the rubber plate 1806 will be squeezed. As the rubber plate 1806 is squeezed and descends, the movable rod 1805 will be squeezed, causing the movable rod 1805 to move. Through the movement of the movable rod 1805, the damping sleeve 1803 will be pushed, causing the damping sleeve 1803 to slide on the sliding rod 1802. As a result, the damping sleeve 1803 will squeeze the first spring 1804, causing the first spring 1804 to deform. At the same time, when the rubber plate 1806 descends, it will also drive the damping block 1807 to descend. Due to the descent of the damping block 1807, the telescopic rod 1808 and the second spring 1809 will be squeezed, causing the second spring 1809 to deform. At the same time, when the first spring 1804 and the second spring 1809 rebound, through the action of the telescopic rod 1808 and the sliding rod 1802, the first spring 1804 and the second spring 1809 will not swing significantly during the rebound, ensuring the purpose of buffering. As a result, after the wear-resistant balls fall to the bottom of the main body 1, the stirring blades 6 and the pushing plate 8 will not be damaged.

[0037] Secondly, after the wear-resistant balls fall to the bottom of the main body 1, by starting the drive motor 4, the drive motor 4 can drive the rotation of the rotating rod 5. Through the rotation of the rotating rod 5, the rotation of the stirring blades 6 can be driven. Through the rotation of the stirring blades 6, the rotation of the connecting rod 7 and the pushing plate 8 can be driven. At the same time, the operating power of the drive motor 4 is set to the minimum, so that the stirring blades 6 and the pushing plate 8 can slowly push the wear-resistant balls, thus avoiding damage to the stirring blades 6 and the pushing plate 8.

[0038] Finally, after the wear-resistant balls are heated at high temperature, by pulling the limiting rod 23, after the limiting rod 23 is separated from the limiting groove 26, by rotating the rotating rod 20, the rotating rod 20 can drive the rotation of the gear 19. Through the rotation of the gear 19, the toothed plate 15 can be driven to move on the sliding rod 14, so that the toothed plate 15 no longer blocks the holes, allowing the wear-resistant balls to fall into the cooling box 13 for cooling. At the same time, after the wear-resistant balls are cooled, by opening the door on the main body 1 and then pulling out the cooling box 13, the wear-resistant balls are collected, thus completing the calcination operation of the wear-resistant balls.

[0039] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
