Description

Technical Field

[0001] The utility model relates to the technical field of ceramic production material stone sorting, and particularly relates to a mobile material stone sorting device. Background Art

[0002] In the ball milling process of ceramic enterprises, it is necessary to grind the mud and sand materials excavated from the mine according to the set formula ratio. However, since the raw ore sand materials excavated from the mine may contain many large stones and sundries, during the process of feeding with a forklift, the feeding port of the feeder or the continuous ball inlet port may be blocked. In addition, when stones enter the continuous ball mill, they will damage the rubber lining of the ball mill, affecting the grinding efficiency of the ball mill, resulting in frequent replacement of the rubber lining of the ball mill and high maintenance costs. At the same time, it causes high failure rates of the feeder and the ball mill, and the feeder reamer and the ball mill feed inlet need to be frequently repaired, resulting in high labor intensity for employees. If the problem of stones in the sand materials cannot be well solved, it will also affect the continuous stability of production and the production capacity.

[0003] In view of the above situation, the industry generally sorts the sand materials through a screening device to screen out the large stones in the sand materials, so as to retain the sand materials. Most of the discharge ports of the existing sand and stone screening mechanisms are relatively low. During transportation, a collection device and a transportation device need to cooperate. For example, Chinese Patent Publication No. CN215997460U discloses "a stone removing machine with multi-stage screening functions", which includes a housing, a feed hopper, a first vibrating screen and a second vibrating screen. The first vibrating screen and the second vibrating screen are arranged up and down. By screening the stones put into the feed hopper, finally the stones of appropriate size are discharged through the discharge hopper. However, its discharge hopper is arranged at the bottom, and the stones are piled on the ground, which is not convenient for direct collection and transportation.

[0032] In view of the deficiencies of the prior art, the present embodiment provides a mobile stone sorting device, which can be specifically referred to as follows:

[0033] As shown in the Figure 1 and Figure 2 figures, a mobile stone sorting device includes a frame 1, a feed hopper 2, a first conveyor belt 11, a screen 3, and a vibrator 4. The feed hopper 2 is arranged at the top of the frame 1. The feed hopper 2 is in an inverted conical shape, and openings are provided at both the top and the bottom of the feed hopper 2 to facilitate feeding and discharging. A first conveyor belt 11 is also arranged on the frame 1. A screen 3 is arranged on the top of the first conveyor belt 11. The screen 3 is located at the bottom of the feed hopper 2 so that the stones inside the feed hopper 2 all fall on the screen 3. A vibrator 4 is arranged on the screen 3. The vibrator 4 is a prior art device and can drive the screen 3 and the first conveyor belt 11 at the bottom of the screen 3 to vibrate together through its own vibration. One end of the first conveyor belt 11 is located at the bottom of the screen 3, and the other end is higher than the screen 3, that is, the first conveyor belt 11 is arranged in an inclined shape.

[0034] Specifically, an external forklift can send the sand and gravel through the inlet at the top of the feed hopper 2 into the feed hopper 2, and then discharge it through the outlet at the bottom of the feed hopper 2 onto the screen 3. At the same time, the vibrator 4 is started. The vibrator 4 drives the screen 3 to vibrate, and the small particle stones and sand are vibrated and dropped onto the first conveyor belt 11 through the screen 3. The first conveyor belt 11 rotates from the lower end to the higher end. At this time, the vibrator 4 will also drive the first conveyor belt 11 to vibrate, so that the small stones can also vibrate and slide off from the inclined first conveyor belt 11. Since one end of the first conveyor belt 11 is arranged at a higher position, a vehicle can be arranged at the higher end position of the first conveyor belt 11, and the sorted sand can be directly transported into the vehicle through the first conveyor belt 11 for direct transportation. Compared with the prior art, the present application is simple and convenient, and can directly collect and transport the sand, effectively improving the sand sorting and transportation efficiency.

[0035] In an embodiment of the present application, a retaining groove is provided on the surface of the first conveyor belt 11. The retaining grooves are arranged at intervals along the length direction of the belt on the first conveyor belt 11, that is, retaining grooves are provided on the belt surface of the first conveyor belt 11, and the retaining grooves penetrate along the width direction of the belt. The cross-section of the retaining groove can be conical, arc-shaped or rectangular. The retaining groove can be used to place sand materials with a smaller diameter. The small stones on the first conveyor belt 11 can slide down along the inclined direction of the first conveyor belt 11 through vibration, while the sand materials rise to the top as the retaining groove moves and fall into the storage box of the vehicle.

[0036] In an embodiment of the present application, a second conveyor belt 5 is provided at the bottom of the feed hopper 2. The screen 3 is located at one end of the second conveyor belt 5 and is lower than the second conveyor belt 5; the feed hopper 2 is located at the rear end of the frame 1, while the screen 3 is located at the front end of the conveyor belt. The sand and gravel materials at the bottom outlet of the feed hopper 2 need to be transported to the bottom of the screen 3 through the second conveyor belt 5, so as to ensure that the sand and gravel materials can be normally screened.

[0037] In this embodiment, the feed hopper 2 is arranged at the rear end of the frame 1, while the screen 3 is located at the front end of the frame 1, in order to ensure that the sand materials and small stones screened by the screen 3 fall at one end of the first conveyor belt 11, so that the sand materials and small stones can run for a sufficient long time, and the small stones are vibrated and slid down by the vibrator 4; the feed hopper 2 is arranged at the rear end of the frame 1, while the screen 3 is located at the front end of the frame 1, and it is also to ensure the overall stability of the frame 1.

[0038] In this embodiment, first baffles 6 are respectively provided on both sides of the bottom of the feed hopper 2. Both first baffles 6 are located on the top of the second conveyor belt 5; specifically, the two first baffles 6 are arranged obliquely and both face the second conveyor belt 5 and are located on the top of the second conveyor belt 5, so that the sand and gravel materials sliding down from the feed hopper 2 all fall on the second conveyor belt 5 to prevent them from sliding off both sides of the second conveyor belt 5, resulting in a reduction in screening efficiency.

[0039] Furthermore, the width of the second conveyor belt 5 is greater than the width of the bottom outlet of the feed hopper 2, so that the first baffle 6 does not need to be provided.

[0040] In an embodiment of the present application, a shock absorber (not shown in the figure) is provided at the bottom of the first conveyor belt 11. The end of the shock absorber away from the first conveyor belt 11 is arranged on the frame 1; when the vibrator 4 vibrates, the vibration of the frame 1 can be reduced through the shock absorber.

[0041] In this embodiment, the vibrator 4 can be a vibration motor, and the vibration motor is a prior art.

[0042] In an embodiment of the present application, second baffles 7 are respectively arranged on both sides of the bottom of the screen 3, and the two second baffles 7 are located on the top of the first conveyor belt 11; the two second baffles 7 are arranged obliquely and both face the first conveyor belt 11. Through the action of the two second baffles 7, the sand materials screened out by the screen 3 can all fall on the first conveyor belt 11 and then be conveyed, preventing the sand materials from falling from both sides of the first conveyor belt 11.

[0043] In an embodiment of the present application, edge guards are arranged on both sides of the first conveyor belt 11 and the second conveyor belt 5; the edge guards arranged on both sides of the first conveyor belt 11 are not only to prevent the sand materials from slipping during transportation, but also to prevent the small stones that have slipped from falling between the upper and lower belts of the first conveyor belt 11, resulting in the small stones getting stuck at the conveying shaft of the first conveyor belt 11, thus causing damage to the first conveyor belt 11; the edge guards are arranged on both sides of the second conveyor belt 5 to prevent the sand and gravel materials from falling between the upper and lower belts of the second conveyor belt 5 and avoid damage to the second conveyor belt 5.

[0044] As shown in the Figure 1 and Figure 2 figure, the mobile stone sorting device further includes wheels 8, a driving assembly 9 and a steering assembly 10. The wheels 8 are arranged at the bottom of the frame 1 and are located at the four corners of the frame 1 to facilitate the movement of the frame 1; a driving assembly 9 is also arranged at the bottom of the frame 1. The driving assembly 9 can be a motor, and the motor is connected to the wheels 8 through gear transmission to drive the wheels 8 to rotate; the two wheels 8 at the front end of the frame 1 are rotatably arranged on the frame 1. The rotating assembly includes a rotating rod, and the rotating rod can drive the wheels 8 to turn through bevel gear cooperation with a driving rod (specifically, reference can be made to the automobile steering structure. Here, the steering assembly 10 is a prior art). Through the cooperation of the driving assembly 9, the rotating assembly and the wheels 8, the movement and turning of the frame 1 can be realized.

[0045] In this embodiment, the driving assembly 9 can also be other structures. Specifically, reference can be made to the driving structure of an automobile through a piston. Here, the driving assembly 9 is a prior art.

[0046] In an embodiment of the present application, one end of the first conveyor belt 11 is rotatably arranged on the frame 1, and a lifting rod is rotatably arranged at the bottom of the other end. The lifting rod is rotatably arranged on the frame 1; when a shock absorber is arranged at the bottom of the first conveyor belt 11, one end of the first conveyor belt 11 and one end of the lifting rod are both rotatably arranged on the shock absorber; specifically, by extending the lifting rod, the inclination angle of the first conveyor belt 11 relative to the frame 1 can be adjusted, so as to adjust the height of the end of the first conveyor belt 11 far from the screen 3, and it is applicable to vehicles of different heights to facilitate the collection and transportation of sand materials.

[0047] Further, the lifting rod is a hydraulic telescopic rod or an electric telescopic rod.

[0048] In this embodiment, the screen 3 is arranged obliquely; specifically, one end of the screen 3 close to the second conveyor belt 5 is higher than the end of the screen 3 far from the second conveyor belt 5, so that the stones on the screen 3 can slide down through the inclined surface of the screen 3.
