[0002] Utility model patent CN219545840U discloses a scraper conveyor guard, including a side cover and a top cover. An inner support plate and an outer support plate are fixedly connected to the lower end of the side cover. Two pairs of rollers are rotatably connected between the inner and outer support plates. Two pairs of locking mechanisms are fixedly connected to the surface of the outer support plate. Each locking mechanism includes a central rod fixedly connected to the surface of the outer support plate, a limit plate fixedly connected to the end of the central rod, and a movable plate slidably connected to the outer surface of the central rod. A spring is sleeved on the outer surface of the central rod between the movable plate and the limit plate. An outer sleeve, a pin, and a clamping pin are fixedly connected to the surface of the movable plate. When the guard needs to be fixed, simply rotate the outer sleeve. Under the spring force, the pin inserts into the fixing hole, limiting and fixing the rollers. The clamping pin also clamps against the central groove of the scraper conveyor, thus fixing the entire guard. The operation is simple and convenient, greatly saving working time.

[0003] However, the above-mentioned mechanism has the following problems: In order to achieve convenient fixing of the protective cover, in addition to the outer tube itself and its internal structure, a roller mechanism is also designed, which is cumbersome and increases the cost of the device excessively; in addition, in order to achieve adjustment of the width of the top cover, an additional internal plate is added to the device, which not only increases the cost of the device, but also makes the device too heavy, which is not conducive to the use of the device. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a protective cover for a mining scraper conveyor, which solves the problem that existing scraper conveyor covers use a relatively cumbersome structure to achieve convenient fixing of the cover and adjustment of the cover width, thus increasing the cost of the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective cover for a mining scraper conveyor, comprising a protective cover and a quick-fixing assembly. The protective cover includes two side plates, and a top plate one and a top plate two are welded to the top sides of the two side plates respectively. A snap-fit ​​strip and a snap-fit ​​groove are respectively formed on the top plate one and the top plate two. The snap-fit ​​strip is slidably inserted into the snap-fit ​​groove. The quick-fixing assembly includes an outer shell, one end of which is connected to an end plate. A slide rod is slidably installed on the inner side of the outer shell. A through hole for movably installing steel balls is opened on the curved side of the outer shell. A spring is filled between the slide rod and the outer shell. The outer shell is slidably inserted into the scraper conveyor frame and the side plates. The steel balls and the end plate are respectively attached to the sides of the scraper conveyor frame and the side plates.

[0006] The beneficial effects of this utility model are as follows: the scraper conveyor frame and the protective cover can be quickly connected by directly inserting the quick-fixing component, and the quick-fixing component relies on springs and steel balls to lock the scraper conveyor frame and the protective cover, which has a simple structure and stable connection; the width of the protective cover can be adjusted effortlessly by sliding the adjustment strip in the locking groove.

[0007] To ensure the stability of the connection between the card strip and the card slot;

[0008] As a further improvement to the above technical solution: the snap-fit ​​groove is a dovetail groove structure, and the corners of the snap-fit ​​groove are formed with rounded corners.

[0009] The beneficial effects of this improvement are: the dovetail groove type snap-fit ​​groove can stably cooperate with the snap-fit ​​strip, ensuring a sliding fit while preventing the snap-fit ​​strip from disengaging from the snap-fit ​​groove, and the rounded corner design can effectively reduce stress concentration.

[0010] In order to effectively improve the support strength of the protective cover;

[0011] As a further improvement to the above technical solution: there are multiple snap-fit ​​strips and snap-fit ​​slots, which are equidistantly spaced on top plate one and top plate two, respectively.

[0012] The beneficial effects of this improvement are: the multiple snap-fit ​​strips and snap-fit ​​grooves serve to connect the two side plates on the one hand, and on the other hand, they can act as reinforcing ribs, thereby improving the structural strength of top plate one and top plate two.

[0014] As a further improvement to the above technical solution: a fixing plate is connected to the end face of the end plate facing away from the steel ball, and the fixing plate is a stepped tube structure.

[0015] The beneficial effects of this improvement are: the operator can hook the fixing plate with two fingers and press the slide bar inward with the thumb to easily insert the outer shell into the scraper conveyor frame and the protective cover.

[0016] To ensure the stability of the slide bar's support for the steel balls;

[0017] As a further improvement to the above technical solution: the slide bar is sequentially formed with a sliding section, a tapered section and a support section, and the difference between the diameter of the sliding section and the inner diameter of the outer shell is not less than the radius of the steel ball.

[0018] The beneficial effects of this improvement are: the support section can support the steel balls, so that the steel balls are stably clamped on both sides of the scraper conveyor frame and the guard with the end plate.

[0019] To ensure the stability of the steel balls when mounted on the outer casing;

[0020] As a further improvement to the above technical solution: the diameter of the slots at both ends of the slot for installing steel balls that is opened through the outer shell is not greater than the diameter of the steel balls.

[0021] The beneficial effect of this improvement is that the steel ball can move inside the outer shell without falling to the inside or outside of the outer shell.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Example 1:

[0030] like Figure 1As shown in Figure 4: A protective cover for a mining scraper conveyor includes a cover 2 and a quick-fixing assembly 3. The cover 2 includes two side plates 21, and a top plate 22 and a top plate 23 are welded to the top sides of the two side plates 21 respectively. A snap-fit ​​strip 24 and a snap-fit ​​groove 25 are respectively formed on the top plate 22 and the top plate 23. The snap-fit ​​strip 24 is slidably inserted into the snap-fit ​​groove 25. The quick-fixing assembly 3 includes a housing 31, one end of which is connected to an end plate 32. A slide rod 33 is slidably installed on the inner side of the housing 31. A through hole for movably installing a steel ball 34 is opened on the curved side of the housing 31. The slide rod 33 is connected to the housing 31. The outer shell 31, filled with spring 35, is slidably inserted into the scraper conveyor frame 1 and side plate 21. Steel balls 34 and end plates 32 are respectively attached to the sides of the scraper conveyor frame 1 and side plate 21. The scraper conveyor frame 1 and cover 2 can be quickly connected by directly inserting the quick-fixing assembly 3. The quick-fixing assembly 3 relies on springs and steel balls to lock the scraper conveyor frame 1 and cover 2, resulting in a simple structure and stable connection. The width of the cover 2 can be easily adjusted by sliding the adjusting strip 24 in the adjusting groove 25. The adjusting groove 25 has a dovetail groove structure with rounded corners. The dovetail groove 25 can be used with the adjusting strip 24. A stable fit is ensured, preventing the locking strip 24 from disengaging from the locking groove 25 while maintaining a sliding fit. The rounded corner design effectively reduces stress concentration. Multiple locking strips 24 and locking grooves 25 are provided, equidistantly spaced on top plate 1 22 and top plate 23. These multiple locking strips 24 and locking grooves 25 serve two purposes: connecting the two side plates 21 and acting as reinforcing ribs to improve the structural strength of top plate 1 22 and top plate 23. A fixing plate 36 is connected to the end face of the end plate 32 facing away from the steel ball 34. The fixing plate 36 has a stepped tubular structure, allowing the operator to hook the fixing plate 36 with two fingers and press inward with their thumb to slide the plate. The rod 33 allows the outer shell 31 to be easily inserted into the scraper conveyor frame 1 and the protective cover 2. The rod 33 is sequentially formed with a sliding section 332, a tapered section 331, and a support section 333. The difference between the diameter of the sliding section 332 and the inner diameter of the outer shell 31 is not less than the radius of the steel ball 34. The support section 333 can support the steel ball 34, so that the steel ball 34 is stably clamped on both sides of the scraper conveyor frame 1 and the protective cover 2 in conjunction with the end plate 32. The diameter of the slots at both ends of the through slot for installing the steel ball 34 on the outer shell 31 is not greater than the diameter of the steel ball 34. The steel ball 34 can move inside the outer shell 31 without falling to the inner or outer sides of the outer shell 31.

[0031] The working principle of this technical solution is as follows: When installing the protective cover 2 on the scraper conveyor frame 1, the side of the side plate 21 is placed against one side of the scraper conveyor frame 1, and the through hole on the side plate 21 is aligned with the mounting hole on the scraper conveyor frame 1. Then, two fingers hook the fixing plate 36, and the thumb presses inward on the sliding rod 33, so that the sliding section 332 moves to the inside of the steel ball 34. Then, the outer shell 31 is slidably inserted into the hole on the side plate 21 and the scraper conveyor frame 1, so that the end plate 32 is against the side plate 21. Release the slide bar 33. At this time, under the elastic support of the spring 35, the slide bar 33 moves away from the outer shell 31. The steel ball 34 contacts the conical section 331 and the support section 333 in sequence. Supported by the support section 333, it is stably pressed against the inner side of the scraper frame 1. Together with the end plate 32, the protective cover 2 is stably connected to the scraper frame 1. When installing the other side plate 21, the overall width of the protective cover 2 can be adjusted by sliding the adjustment strip 24 in the locking groove 25.
