Description

Technical Field

[0001] The utility model belongs to the technical field of stone crushers, and particularly relates to a quantitative feeding mechanism for a stone crusher. Background Technique

[0002] A stone crusher is a mechanical device that crushes large rocks into crushed stones by means of extrusion, splitting, bending, impact, rolling, etc. Due to its high crushing efficiency and good crushing effect, it is increasingly favored by building material manufacturers.

[0003] The working efficiency of a stone crusher is related to the operating efficiency of the entire production line, and the large feeding volume of raw stones generally affects the working efficiency of the stone crusher. At present, during the process of crushing stones by a stone crusher, the feeding volume of the stone crusher is usually not controlled, which will cause the problem that the feeding port of the crusher is blocked due to too large a feeding volume, thus affecting the working efficiency of the stone crusher. Therefore, it is urgent to study a quantitative feeding mechanism for a stone crusher to solve the above problems. Content of the Utility Model

[0004] The utility model aims to provide a quantitative feeding mechanism for a stone crusher, and its purpose is to solve the technical problems raised in the above background technique.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a quantitative feeding mechanism for a stone crusher, including a horizontally arranged support plate; an avoidance notch is provided at one edge of the support plate; a pair of frames are fixedly arranged side by side on the lower surface of the support plate; a belt conveying component is horizontally installed above the support plate; a plurality of stone quantitative hoppers are connected side by side on the belt conveying component; baffles corresponding to the avoidance notch are rotatably connected at the lower ports of the plurality of stone quantitative hoppers; when the lower surface of the baffle is in contact with the upper surface of the support plate, the lower port of the stone quantitative hopper is blocked by the baffle; when any one of the stone quantitative hoppers moves directly above the avoidance notch, the baffle connected to the stone quantitative hopper rotates downward to release the blockage of the lower port of the stone quantitative hopper, and as the stone quantitative hopper continues to move, the baffle connected to the stone quantitative hopper abuts against one edge of the avoidance notch and then resets.

[0007] As a preferred technical solution of the utility model, the support plate is in a rectangular frame structure; the avoidance notch is arranged on one edge of the support plate; the belt conveying component is installed inside the support plate.

[0008] As a preferred technical solution of the present utility model, a pair of mounting frames are vertically and fixedly arranged side by side on the other edge of the support plate; a feed hopper corresponding to the stone metering hopper is vertically fixed between the two mounting frames; when any one of the stone metering hoppers moves below the feed hopper, the stones in the feed hopper fall into the stone metering hopper.

[0009] As a preferred technical solution of the present utility model, the belt conveying assembly includes a pair of mounting plates horizontally and fixedly arranged on the two frames respectively; the upper surfaces of the two mounting plates are vertically rotatably connected with rotating shafts; the two rotating shafts are arranged inside the support plate; a servo motor is vertically arranged on one side of one of the rotating shafts; the servo motor is fixed on one mounting plate, and the output shaft of the servo motor penetrates through the mounting plate and is fixedly sleeved with a first belt pulley; the first belt pulley is connected with a second belt pulley through a synchronous belt; the second belt pulley is fixedly sleeved on one of the rotating shafts; the upper ends of the two rotating shafts are fixedly sleeved with rollers; the two rollers are connected by a plurality of conveyor belts; a plurality of connecting blocks are fixedly arranged side by side along the length direction on each conveyor belt; positioning plates are vertically fixed on the plurality of connecting blocks; the positioning plates are fixed on one side wall of the stone metering hopper.

[0010] As a preferred technical solution of the present utility model, a pair of bearing columns are vertically fixed at the bottom of the stone metering hopper; the two bearing columns are arranged on opposite sides of the baffle; the lower ends of the two bearing columns are vertically fixed with movable seats in a "Π" shape; rollers are rotatably connected between the opposite side arms of the movable seat; the rollers are in rolling fit with the upper surface of the support plate.

[0011] The present utility model has the following beneficial effects:

[0012] The utility model drives a plurality of stone metering hoppers to rotate intermittently in a cycle through a belt conveying assembly. When the lower port of any stone metering hopper is blocked by a baffle, stones are poured into the stone metering hopper. Then, the belt conveying assembly is used to drive the stone metering hopper carrying the stones to move on the support plate. After the stone metering hopper moves to directly above the avoidance notch, due to the lack of support and limitation of the support plate for the baffle, the baffle is forced to rotate downward under the pressure of the stones in the stone metering hopper, so as to discharge the stones in the stone metering hopper into the feeding port of the stone crusher through the avoidance notch. Since the size of the stone metering hopper is fixed, quantitative feeding of the stone crusher can be achieved, effectively avoiding the problem that the feeding port of the crusher is blocked due to too large feeding amount in the prior art, and ensuring the working efficiency of the stone crusher. As the stone metering hopper above the avoidance notch continues to move, the baffle connected to the stone metering hopper abuts against one edge of the avoidance notch and then rotates upward to reset, realizing the re-blocking of the lower port of the stone metering hopper, ensuring the repeated use of the stone metering hopper, and effectively ensuring the use effect of the entire quantitative feeding mechanism.

[0013] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1:

[0025] Please refer to Figures 1-4As shown in the figure, the utility model relates to a quantitative feeding mechanism of a stone crusher, which comprises a horizontally arranged support plate 1; a relief notch 101 is formed at one edge of the support plate 1; one edge of the relief notch 101 is bent downward; a pair of conventional machine frames 2 in the field are bolted side by side on the lower surface of the support plate 1; a belt conveying assembly 3 is horizontally installed above the support plate 1; a plurality of stone quantitative hoppers 4 are connected side by side on the belt conveying assembly 3, and each stone quantitative hopper 4 has an upper port and a lower port; a baffle 5 corresponding to the relief notch 101 is rotatably connected at the lower port of each of the plurality of stone quantitative hoppers 4, that is, one edge of the baffle 5 is rotatably connected to one edge of the lower port of the stone quantitative hopper 4 through a core shaft; the size of the baffle 5 is smaller than that of the relief notch 101; when the lower surface of the baffle 5 is in contact with the upper surface of the support plate 1 (that is, when the baffle 5 is in a horizontal state), the lower port of the stone quantitative hopper 4 is blocked by the baffle 5, and at this time, the stones in the stone quantitative hopper 4 cannot be discharged; when any one of the stone quantitative hoppers 4 moves directly above the relief notch 101, the baffle 5 connected to the stone quantitative hopper 4 rotates downward due to the lack of restraint of the support plate 1 on it and releases the blockage of the lower port of the stone quantitative hopper 4, so that the stones in the stone quantitative hopper 4 are discharged into the feed inlet of the stone crusher, and as the stone quantitative hopper 4 continues to move, the baffle 5 connected to the stone quantitative hopper 4 abuts against one edge of the relief notch 101 and then resets, and at this time, the lower port of the stone quantitative hopper 4 is blocked by the baffle 5 on it again. During use, the belt conveying assembly 3 drives the plurality of stone quantitative hoppers 4 to rotate intermittently in a cycle. When the lower port of any one of the stone quantitative hoppers 4 is blocked by the baffle 5, stones are poured into the stone quantitative hopper 4, and then the belt conveying assembly 3 drives the stone quantitative hopper 4 carrying the stones to move on the support plate 1. After the stone quantitative hopper 4 moves directly above the relief notch 101, due to the lack of support and limit of the support plate 1 on the baffle 5, the baffle 5 is forced to rotate downward under the pressure of the stones in the stone quantitative hopper 4, so as to realize the discharge of the stones in the stone quantitative hopper 4 into the feed inlet of the stone crusher through the relief notch 101. Since the size of the stone quantitative hopper 4 is fixed, quantitative feeding of the stone crusher can be realized, which not only effectively avoids the problem that the feed inlet of the crusher is blocked due to too large feed amount in the prior art, but also ensures the working efficiency of the stone crusher. As the stone quantitative hopper 4 above the relief notch 101 continues to move, the baffle 5 connected to the stone quantitative hopper 4 abuts against one edge of the relief notch 101 and then rotates upward to reset, realizing the re-blocking of the lower port of the stone quantitative hopper 4, ensuring the repeated use of the stone quantitative hopper 4, and effectively ensuring the use effect of the whole quantitative feeding mechanism.

[0026] Among them, such as Figures 2-4As shown in the figure, on the other edge of the support plate 1, a pair of mounting frames 6 are vertically bolted side by side; between the two mounting frames 6, a feed hopper 7 corresponding to the stone metering hopper 4 is vertically bolted; the feed hopper 7 has an upper port and a lower port; when any one of the stone metering hoppers 4 moves below the feed hopper 7, the stones in the feed hopper 7 fall into this stone metering hopper 4; the upper port of the stone metering hopper 4 is in an inverted quadrangular pyramid structure; after two adjacent stone metering hoppers 4 are arranged side by side, the edges of the upper ports of these two stone metering hoppers 4 are in contact with each other, which can reduce the probability of the stones slipping out of the stone metering hopper 4 when the feed hopper 7 feeds the stones into the stone metering hopper 4. During use, first put the stones into the feed hopper 7, and when any one of the stone metering hoppers 4 moves below the feed hopper 7, the stones in the feed hopper 7 fall into this stone metering hopper 4, thus ensuring the metering feeding effect of the stone metering hopper 4.

[0027] Embodiment 2:

[0028] On the basis of Embodiment 1 as Figure 1 and Figures 4-5 shown, the support plate 1 is in a rectangular frame structure; an avoidance notch 101 is arranged on one edge of the support plate 1; the belt conveying assembly 3 is installed inside the support plate 1; the belt conveying assembly 3 includes a pair of mounting plates 301 respectively horizontally bolted to the two frames 2; on the upper surfaces of the two mounting plates 301, rotating shafts 302 are vertically rotatably connected; the two rotating shafts 302 are both arranged inside the support plate 1; on one side of a rotating shaft 302, a servo motor 303 is vertically arranged; the servo motor 303 is bolted to one mounting plate 301, and the output shaft of the servo motor 303 passes through this mounting plate 301 with a clearance and is key-connected with a first belt pulley 304; the first belt pulley 304 is connected with a second belt pulley 305 through a synchronous belt; the second belt pulley 305 is key-connected to a rotating shaft 302; on the upper ends of the two rotating shafts 302, rollers 306 are key-connected; between the two rollers 306, a plurality of conveyor belts 307 are connected; the plurality of conveyor belts 307 are arranged side by side from top to bottom; on each conveyor belt 307, a plurality of connecting blocks 308 are riveted side by side along the length direction; on the plurality of connecting blocks 308, positioning plates 309 are vertically bolted; the positioning plates 309 are bolted to one side wall of the stone metering hopper 4. During use, the servo motor 303 drives the first belt pulley 304 to rotate intermittently, so that the first belt pulley 304 drives the two rotating shafts 302 to rotate synchronously through the second belt pulley 305, realizing that during the movement of the conveyor belt 307, the stone metering hopper 4 is pulled to move together through the connecting blocks 308 and the positioning plates 309, thereby realizing the cyclic movement of the stone metering hopper 4.

[0029] Among them, as Figures 2-3 and Figure 6As shown in the figure, a pair of load-bearing columns 8 are vertically bolted to the bottom of the stone metering hopper 4; the two load-bearing columns 8 are arranged on opposite sides of the baffle 5; the lower ends of the two load-bearing columns 8 are vertically bolted with movable seats 9 in a "Π" structure, and the horizontal section of the movable seat 9 is connected to the load-bearing column 8; a roller 10 is rotatably connected between the opposite side arms of the movable seat 9; the roller 10 is in rolling fit with the upper surface of the support plate 1. During use, when the stone metering hopper 4 is pulled by the conveyor belt 307, the roller 10 rolls on the upper surface of the support plate 1, which can not only improve the support effect on the stone metering hopper 4, but also reduce the friction between the baffle 5 and the support plate 1, effectively ensuring the service life of the entire metering and feeding mechanism.
