[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a self-cleaning bucket lip guard plate structure for mining machinery, including a plate body 1. A cleaning device 2 is provided on one side of the plate body 1. The cleaning device 2 includes a rectangular groove 21 formed on one side of the plate body 1. A screw 24 is rotatably connected to the inner wall of the rectangular groove 21 via a bearing. The screw 24 is driven by a motor. A screw hole block 25 is threadedly connected to the surface of the screw 24. The surface of the screw hole block 25 is slidably connected to the inner wall of the rectangular groove 21. A scraper 26 is fixedly connected to one side of the screw hole block 25. The surface of the scraper 26 is in contact with the surface of the plate body 1. By setting the cleaning device 2, when the plate body... 1. After use, the motor is started to drive the screw 24 to rotate. During the rotation, the screw 24 drives the screw hole block 25 to move away from the motor along the inside of the rectangular groove 21. The screw hole block 25 drives the scraper 26 to move, so that the scraper 26 moves against the surface of the plate 1 and scrapes off the dirt adhering to the surface of the plate 1. This achieves automatic cleaning of the surface of the plate 1, reduces the long-term adhesion and accumulation of dirt on the plate 1, which leads to accelerated corrosion of the metal plate 1, weakens the anti-wear effect of the plate 1 on the lip, affects the service life and protective effect of the plate 1, and improves the convenience of cleaning the plate 1.
[0027] Specifically, such as Figure 2 and Figure 3 As shown, a scraper 27 is fixedly connected to the side of the scraper 26 away from the scraper 26. The surface of the scraper 27 is in contact with the surface of the plate 1. By setting the scraper 27, the scraper 27 can use its sharp end to scoop up the soil with strong adhesion, further improving the scraping effect of the scraper 26 on the soil. A wear-resistant block 28 is fixedly connected to one side of the scraper 26. The wear-resistant block 28 is made of high chromium alloy. By setting the wear-resistant block 28, when the bucket lip and the plate 1 come into contact with the material, the wear-resistant block 28 can replace the scraper 26 to contact the material, reducing the collision and wear of the material on the scraper 26.
[0028] Specifically, such as Figure 2 and Figure 3As shown, an arc-shaped plate 22 is fixedly connected to the inner wall of the rectangular groove 21. An arc-shaped hole 29 is opened on one side of the screw hole block 25. The arc-shaped plate 22 is placed above the screw 24 and inside the arc-shaped hole 29. By setting the arc-shaped plate 22, the arc-shaped plate 22 can intercept the material falling into the rectangular groove 21, prevent the material from directly contacting the screw 24, and reduce the impact of the material falling into the rectangular groove 21 on the screw 24. A through hole 23 is opened on one side of the plate body 1. The inner wall of the through hole 23 is connected to the inner wall of the rectangular groove 21. By setting the through hole 23, the screw hole block 25 can push out the material falling into the rectangular groove 21 through the through hole 23 while moving, reducing the impact of the material accumulating in the rectangular groove 21 on the screw 24.
[0029] Specifically, such as Figure 3 and 4 As shown, a blocking device 3 is provided on the side of the plate 1 near the connecting hole. The blocking device 3 includes a stop bar 31, and a screw 32 is provided inside the hole on the stop bar 31. A threaded groove 34 is provided on one side of the plate 1. The surface of the screw 32 is threadedly connected to the inner wall of the threaded groove 34. By setting the blocking device 3, the stop bar 31 is first manually moved to a position that fits against the surface of the plate 1, so that the inner wall of the hole of the stop bar 31 coincides with the inner wall of the threaded groove 34. At this time, the screw 32 is screwed into the position of the stop bar 31 and the threaded groove 34 to fix the position of the stop bar 31, so that the stop bar 31 intercepts the material and separates the material from the bolts used to install the plate 1, so that the two do not come into direct contact. This achieves the protection of the bolts used to install the plate 1, reduces the direct collision and squeezing of the bolts by the material when the plate 1 is installed on the bucket lip by bolts, which causes the bolts to deform and affect the normal maintenance and replacement of the plate 1 by subsequent personnel, and improves the service life of the bolts used to install the plate 1.
[0030] Specifically, such as Figure 3 and Figure 4 As shown, the baffle 31 has multiple grooves 33 on the side near the plate 1. By setting the grooves 33, some material can be discharged through the inside of the grooves 33, reducing the situation where the baffle 31 obstructs the normal discharge of material.
[0031] The working principle of this utility model is as follows:
[0032] S1. In use, plate 1 is fastened to the surface of bucket lip with high-strength bolts and anti-loosening nuts, so that plate 1 covers bucket lip and provides protection. After plate 1 is used, the motor is started to drive screw 24 to rotate. During the rotation, screw 24 drives screw hole block 25 to move away from motor along the inside of rectangular groove 21. Screw hole block 25 drives scraper 26 to move. Scraper 26 moves against the surface of plate 1 and scrapes off the dirt on the surface of plate 1, thereby achieving automatic cleaning of the surface of plate 1.
[0033] S2. First, manually move the stop bar 31 to a position that fits against the surface of the plate 1, so that the inner wall of the hole of the stop bar 31 coincides with the inner wall of the threaded groove 34. At this time, use a tool to screw the screw 32 into the position of the stop bar 31 and the threaded groove 34 to fix the position of the stop bar 31, so that the stop bar 31 intercepts the material and separates the material from the bolts used to install the plate 1, so that the two do not come into direct contact, thereby protecting the bolts used to install the plate 1.
