DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 8 The present invention provides a technical solution: a safety protection device for mining electromechanical equipment, comprising a conveying device for conveying stones and a base frame 1 for accommodating stones, the base frame 1 is provided with a feeding port 3 for throwing stones, the conveying device comprises a conveyor belt 2, and the base frame 1 is provided with a gathering structure for preventing the stones being conveyed from sliding off the conveyor belt 2; The gathering structure comprises a middle plate 4 arranged on the base frame 1, a return spring 7 is fixedly connected to the middle plate 4, one end of the return spring 7 away from the middle plate 4 is fixedly connected to the base frame 1, and a groove body 1 is provided on the base frame 1 for the middle plate 4 to move freely in the vertical direction; The horizontal sides of the middle plate 4 are respectively provided with a guide plate 6 and a position plate 5, the position plate 5 and the guide plate 6 are both fixedly rotated on the middle plate 4, the base frame 1 is provided with a swing angle component for adjusting the horizontal inclination of the guide plate 6, and the base frame 1 is also provided with a pusher component for driving the position plate 5 to reciprocate and deflect to prevent stones from accumulating on the middle plate 4; An inner frame 25 is fixedly connected to the lower part of the base frame 1 , and a centering component for driving the stones to be in the middle of the conveyor belt 2 is arranged on the inner frame 25 .

[0020] like Figure 1-Figure 3As shown, the mined stones are fed into the base frame 1 through the feeding port 3, and then fall onto the middle plate 4 and the isotope plate 5. As the stones are gradually accumulated, the stones on the middle plate 4 and the isotope plate 5 slide through the inclined isotope plate 5 to the opening direction of the base frame 1, and then fall onto the conveyor belt 2.

[0021] At the same time, the inclination angle of the guide plate 6 can be adaptively adjusted according to the amount of stone in the base frame 1 through the swing angle component. When the stone falls on the guide plate 6, the gravity will cause the stone to slide downward along the inclined surface of the guide plate 6. The larger the inclination angle, the greater the downward component of the force on the stone along the inclined surface, and the faster the sliding speed will be. If the inclination angle becomes smaller, the component of the stone along the inclined surface will decrease, and the sliding speed will slow down accordingly. Then, by changing the horizontal inclination angle of the guide plate 6, the sliding speed of the stone on the guide plate 6 can be adjusted. When there are more stones in the base frame 1, the inclination angle of the guide plate 6 becomes slower, the gravity component of the stone decreases, the friction force increases, and the sliding speed of the stone slows down accordingly. Therefore, by controlling the angle of the guide plate 6, the falling speed of the stone can be automatically adjusted, so that the stone falls on the conveyor belt 2 relatively evenly, so as to avoid the problem of uneven load on the conveying equipment, thereby ensuring a stable and uniform transportation process of the stone.

[0022] At the same time, by means of the pushing assembly arranged on the base frame 1, it is possible to prevent excessive stone from being deposited on the median plate 4 and the isotope plate 5. The pushing assembly drives the isotope plate 5 to swing back and forth in the vertical direction, thereby disturbing the stone thereon, to ensure that the stone can smoothly slide to the side of the guide plate 6. Moreover, after the stone slides along the slope of the guide plate 6 onto the conveyor belt 2, the center gathering assembly can control the landing point of the stone on the conveyor belt 2, so that the stone is roughly in the middle of the conveyor belt 2 during the transportation process, thereby preventing the stone from sliding onto the conveyor belt 2 and rolling down, and at the same time preventing the stone from shifting or diffusing, thereby improving the accuracy and efficiency of material transportation.

[0023] In one of the more preferred embodiments, the swing angle assembly includes a positioning pin 11 fixedly connected to the guide plate 6, the guide plate 6 is in sliding contact with the inner wall of the base frame 1, and a horizontal positioning groove 12 is provided on the base frame 1 for the positioning pin 11 to slide horizontally, and the inclined slope direction of the positioning pin 11 corresponds to the position of the conveyor belt 2.

[0024] like Figure 3 As shown, when the stone is put into the base frame 1, the stone first falls onto the middle plate 4 and the isotropic plate 5, and then slides onto the conveyor belt 2 along the slope of the guide plate 6. When the amount of stone carried on the middle plate 4 is too much, the middle plate 4 can move downward under the factor of the stone's gravity, that is, the reset spring 7 can be compressed and deformed under the factor of the stone's gravity.

[0025] At this time, the horizontal height of the middle plate 4 changes, and the positioning pin 11 arranged on the guide plate 6 is slidably connected to the base frame 1 through the horizontal positioning groove 12. Therefore, when the middle plate 4 drives the height of one end of the guide plate 6 to change synchronously, the positioning pin 11 can be driven to slide on the horizontal positioning groove 12, thereby changing the inclination of the guide plate 6. When there are more stones in the base frame 1, the inclination angle of the guide plate 6 becomes slower, the gravity component of the stone is reduced, the friction force is increased, and the sliding speed of the stone is slowed down. Therefore, by controlling the angle of the guide plate 6, the falling speed of the stone can be automatically adjusted, so that the stone falls on the conveyor belt 2 relatively evenly, thereby preventing the stone from excessively accumulating on the conveyor belt 2, so as to avoid the stone rolling down from both sides of the conveyor belt 2 to injure people or jam parts and cause transportation interruption.

[0026] Based on the embodiment of the swing angle assembly, the push assembly includes an extension rod 13 fixedly connected to the middle plate 4, the extension rod 13 is provided with a homonymous disk 14 driven by a motor and freely rotating in the vertical direction, and the homonymous disk 14 is provided with a swing rod 16 freely swinging in the vertical direction; The middle part of the swing rod 16 is fixedly rotated on the extension rod 13 , and one end of the swing rod 16 facing the corresponding plate 5 is fixedly connected with an end ball 18 .

[0027] The base frame 1 is provided with a lateral clearance groove 30 for the same position plate 5 to pass through, a vertical sealing plate 8 is provided above the same position plate 5, and the base frame 1 is provided with a receiving groove 9 for the vertical sealing plate 8 to slide and connect in the vertical direction, and a pressure spring 10 is provided in the receiving groove 9, and the two ends of the pressure spring 10 are respectively fixedly connected to the vertical sealing plate 8 and the base frame 1; One end of the vertical sealing plate 8 away from the pressure spring 10 is always in contact with the upper surface of the corresponding plate 5 .

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the isotropic disk 14 is driven to rotate in the vertical direction by a motor fixed on the extension rod 13, and then the rocker arm 16 is driven to swing at a fixed point in the vertical direction through the continuous rotation process of the isotropic disk 14, wherein an end ball 18 is provided at the end of the rocker arm 16, and when the end ball 18 swings back and forth, it can push the isotropic plate 5 that is in contact with it, thereby changing the angle between the isotropic plate 5 and the middle plate 4, and when the isotropic plate 5 swings, it can disturb the stones piled thereon and push the stones thereon to slide toward the guide plate 6, so as to ensure that the stones can smoothly pass through the guide plate 6 and slide onto the conveyor belt 2.

[0029] At the same time, the isotope plate 5 rotates on the middle plate 4 on a fixed axis. The isotope plate 5 can only deflect upward relative to the middle plate 4. The deflection direction of the isotope plate 5 can be limited by setting a block on the middle plate 4, thereby avoiding the deflection of the isotope plate 5 caused by the accumulation of stones above the two.

[0030] It should be noted that a freely retractable vertical sealing plate 8 is provided above the isotope plate 5. When the amount of stone piled above the middle plate 4 and the isotope plate 5 is different, the horizontal heights of the middle plate 4 and the isotope plate 5 will change, and the slope of the guide plate 6 will be driven to change. In order to prevent the stone from sliding out of the base frame 1 from one side of the isotope plate 5, a receiving groove 9 and a pressure spring 10 are provided on the base frame 1 to ensure that the vertical sealing plate 8 can always be in contact with the isotope plate 5, thereby blocking one side of the isotope plate 5 to ensure the sliding direction of the stone. At the same time, when the isotope plate 5 is deflected, it can push the vertical sealing plate 8 to drive the vertical sealing plate 8 to retract into the receiving groove 9, and the bottom of the vertical sealing plate 8 can always be in contact with the isotope plate 5, so that the existence of the vertical sealing plate 8 will not interfere with the movement process of the isotope plate 5.

[0031] Furthermore, one end of the same position plate 14 facing the swing rod 16 is fixedly connected to a limit pin 15, and the swing rod 16 is provided with a limit slot 17 for the limit pin 15 to be slidably connected; A rack 20 is provided below the swing rod 16 and reciprocates in the horizontal direction.

[0032] like Figure 4 and Figure 6 As shown, when the isotropic disk 14 rotates freely in the vertical direction, it can drive the limit pin 15 fixed thereon to rotate synchronously, wherein the limit pin 15 is slidably connected to the rocker arm 16 through the limit groove 17, and the horizontal position of the limit pin 15 changes with the rotation of the isotropic disk 14. Therefore, the limit pin 15 can drive the rocker arm 16 to swing in the vertical direction by changing its own horizontal position, and then when the isotropic disk 14 rotates in a circle, it can drive the rocker arm 16 to swing back and forth in the vertical direction, so as to drive the end ball 18 at the end of the rocker arm 16 to swing and push the isotropic plate 5 to deflect.

[0033] Based on the embodiment of the pusher assembly, the middle gathering assembly includes a T-shaped rod 23 that moves horizontally synchronously with the rack 20, and a rectangular groove for the T-shaped rod 23 to slide through is opened on the inner frame 25. The T-shaped rod 23 is provided with two groups of transverse rods 28 that move synchronously toward or away from each other in the horizontal direction. The opposite surfaces of the two groups of transverse rods 28 are fixedly connected with a group of push plates 29, and the push plates 29 are located above the conveyor belt 2; Two sets of rectangular sliders 24 are slidably sleeved on the T-shaped rod 23, and upper and lower sides of the rectangular slider 24 are respectively provided with an upper connecting rod 26 and a lower connecting rod 27, and the two ends of the upper connecting rod 26 are respectively fixedly rotated on the rectangular slider 24 and the transverse rod 28, and the two ends of the lower connecting rod 27 are respectively fixedly rotated on the rectangular slider 24 and the inner frame 25; The inner frame 25 is provided with a through slot for the traverse rod 28 to slide through in the horizontal direction.

[0034] like Figure 1 , Figure 2 and Figure 8 As shown, when the T-rod 23 follows the rack 20 to move in the horizontal direction and the horizontal position changes, the rectangular slider 24 slidably mounted thereon slides on the T-rod 23 under the restriction of the lower connecting rod 27, wherein when the rectangular slider 24 slides on the T-rod 23, the upper connecting rod 26 can be driven to deflect, and one end of the upper connecting rod 26 away from the rectangular slider 24 is fixedly rotated on the transverse rod 28, thereby driving the transverse rod 28 to move in the horizontal direction.

[0035] Among them, a push plate 29 is fixedly connected to the transverse rod 28, and the push plate 29 is above the conveyor belt 2. The push plate 29 is a sideways V-shaped structure. Under the restriction of the push plate 29, it can prevent the stones sliding out from the guide plate 6 from splashing and injuring people, so that the stones sliding out from the guide plate 6 can all fall on the conveyor belt 2.

[0036] At the same time, the T-bar 23 follows the rack 20 to reciprocate in the horizontal direction. The movement of the T-bar 23 drives the two groups of push plates 29 to move synchronously toward or away from each other in the horizontal direction. When the two groups of push plates 29 move toward each other, they can gather the stones that have fallen on the conveyor belt 2, so that the stones are roughly in the middle position of the conveyor belt 2, thereby preventing the stones from falling from both sides of the conveyor belt 2 during transportation, thereby preventing the stones from rolling down from both sides of the conveyor belt 2 to injure people or jam parts and cause transportation interruption.

[0037] Furthermore, the end of the swing rod 16 away from the end ball 18 is fixedly connected to a sector gear 19, the sector gear 19 is meshingly connected to the rack 20, and the extension rod 13 is fixedly connected to a ladder frame 21, and the ladder frame 21 is provided with a transverse slide groove for the rack 20 to be horizontally slidably connected; The T-shaped rod 23 is fixedly connected to an H-shaped frame 22 on one side facing the rack 20 . The H-shaped frame 22 is provided with a vertical sliding groove 31 for the rack 20 to slide and connect in a vertical direction.

[0038] like Figure 2 , Figure 4 and Figure 8As shown, when the rocker arm 16 swings back and forth in the vertical direction, it can drive the sector gear 19 fixed thereon to swing synchronously, and the sector gear 19 is meshedly connected with the rack 20. Therefore, the swinging process of the rocker arm 16 can drive the rack 20 to reciprocate in the horizontal direction.

[0039] It should be noted that the horizontal heights of the center plate 4, the outriggers 13, the ladder frame 21 and the components thereon will change with the amount of stone piled on the center plate 4, but the horizontal heights of the inner frames 25 and the T-bar 23 will not change. Therefore, in order to ensure that the T-bar 23 can move horizontally synchronously with the rack 20, an H-shaped frame 22 is fixedly provided on the T-bar 23, and a vertical slide groove 31 is provided on the H-shaped frame 22 for the rack 20 to slide vertically, thereby adapting to the height change of the rack 20 and being able to drive the T-bar 23 to move synchronously when the rack 20 moves horizontally.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
