[0003] Currently, when screening aggregates, it is usually to use a conveyor belt to transport the aggregates to the screening device, and the screening device is used to screen the aggregates. As the screening device is used for a long time, the screened aggregates usually directly fall above the screen, which is easy to cause blockage of the screen and affect the normal use of the screening device.
[0004] Therefore, we propose a multi-angle grading screening device to facilitate solving the problems mentioned above. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problems mentioned above.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A multi-angle grading screening device, including a rotating ring and a plurality of support legs installed at the lower part of the rotating ring.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.
[0021] Embodiment 1
[0022] A multi-angle grading and screening device includes a rotating ring 1. A number of support legs 2 are installed at the bottom of the rotating ring 1. Through the arrangement of the support legs 2, the rotating ring 1 is supported, so that there is a certain gap between the rotating ring 1 and the ground, which can ensure that the conveying end of the conveyor b (the conveyor is already in the prior art and will not be described in detail in this application) is placed below the rotating ring 1. It should be noted that: the support legs 2 are directly placed on the ground, replacing the traditional fixed connection method between the support legs 2 and the conveyor b. The advantage of this method is that the screening device is relatively flexible and can rotate the rotating ring 1 according to the user's needs, so that the rotating ring 1 can drive the screening box 4 to adjust at multiple angles, thereby changing the orientation of the feeding hopper 12; it should also be noted that: the number of support legs 2 is selected according to the user's needs to avoid interference caused by too many support legs 2 when the rotating ring 1 rotates.
[0023] A number of groups of support components 3 are installed along the circumferential direction at the top of the rotating ring 1, and the number of support components 3 is preferably 4. It should be noted that: the heights of two of the support components 3 are relatively high, and the heights of the other two support components 3 are relatively low, and the same inclined screening box 4 is installed on the four support components 3. It should be noted that: the angle between the screening box 4 and the ground is 10° - 20°, and the angle between the screening box 4 and the ground is preferably 15°. The larger aggregates screened out by the sieve mesh 5 can flow along the inclined surface of the sieve mesh 5 to the position of the feeding hopper 12, reducing the phenomenon of blockage caused by the accumulation of the screened aggregates on the sieve mesh 5 and ensuring the stability of the screening device; a sieve mesh 5 is installed at the upper part of the screening box 4. Through the arrangement of the sieve mesh 5, the aggregates are screened. An opening 6 is provided at one end of the screening box 4, and the larger particles of the aggregates screened out by the sieve mesh 5 can flow out of the screening box 4 from the position of the opening 6. A discharge opening 7 is also provided at the lower part of the screening box 4. Through the arrangement of the discharge opening 7, the smaller aggregates screened out by the sieve mesh 5 can be discharged from the discharge opening 7.
[0024] A number of mutually parallel reinforcing rods 11 are installed inside the screening box 4. Through the arrangement of the reinforcing rods 11, the screening box 4 is reinforced, reducing the situation of deformation of the screening box 4.
[0025] "U"-shaped mounting rods 9 are fixed on both inner side walls of the screening box 4. Both ends of the sieve mesh 5 are slidably installed inside the "U"-shaped mounting rods 9, so that the sieve mesh 5 can be taken out from the two mounting rods 9, and the sieve mesh 5 can be replaced. A number of mounting holes (not shown in the figure) are equidistantly provided on the mounting rods 9, and fixing bolts 10 for fastening the sieve mesh 5 are threadedly installed inside the mounting holes. Through the arrangement of the fixing bolts 10, the sieve mesh 5 is fastened, preventing the sieve mesh 5 from loosening during use.
[0026] A discharge hopper 12 is installed at the position of the opening 6. Through the setting of the discharge hopper 12, the larger-sized aggregate screened by the screen 5 can flow along with the discharge hopper 12, so that the larger-sized aggregate can fall into a position farther away from the screening device, which is convenient for cleaning and avoids the screened aggregate falling below the screening device, resulting in inconvenient cleaning due to the obstruction of the screening device.
[0027] When screening the aggregate, first place the screening device between two conveyors, so that the output end of one conveyor a is located above the screen 5, and the conveying end of the other conveyor b is placed below the discharge opening 7. After the placement is completed, as Figure 1 shown;
[0028] The aggregate on the conveyor a is slowly conveyed onto the screen 5. Through the screen 5, the aggregate can be screened. The smaller-sized aggregate can fall from the screen 5. The fallen aggregate falls into the conveyor b through the discharge opening 7. The screened aggregate is conveyed by the conveyor b. The larger-sized aggregate can be screened out by the screen 5. The larger-sized aggregate can flow downward along with the screen 5, so that the larger-sized aggregate falls from the opening 6 onto the discharge hopper 12, and the larger-sized aggregate falls into the designated position through the discharge hopper 12 and is collected.
[0029] Embodiment 2
[0030] Although in the above Embodiment 1, the screening box is set at a certain inclination angle, and the screened aggregate flows along the inclined surface of the screen towards the position of the discharge hopper 12; this can reduce the phenomenon of blockage of the aggregate on the screen due to excessive amount; however, during the flow of the screened aggregate on the screen, since there are many screening holes on the screen, the screened aggregate is likely to get stuck in the screening holes during the flowing process, and it will also cause the problem of blockage of the screen; therefore, in order to solve the above-mentioned technical problems, improvements are made on the basis of Embodiment 1.
[0031] Vibration motors 8 are installed on both sides of the screening box 4. When the vibration motors 8 cooperate with a number of support components 3, the screening box 4 can be driven to vibrate repeatedly. Furthermore, the screening box 4 can drive the aggregate on the screen 5 to vibrate repeatedly, so that the screened aggregate moves towards the position of the discharge hopper 12 under vibration, reducing the situation where the screened aggregate gets stuck in the screening holes during the flowing process towards the position of the discharge hopper 12.
[0032] Specifically: The support assembly 3 includes a fixed shaft 31 fixed to the side wall of the screening box 4. A sleeve 32 is sleeved on the fixed shaft 31, and a spring 33 is fixed to the lower part of the sleeve 32. The spring 33 can drive the screening box 4 to move up and down. The bottom end of the spring 33 is fixed to a fixed rod 34, and the fixed rod 34 is fixed to the top of the rotating ring 1. Through the setting of the support assembly 3, on the one hand, it plays a role in supporting the screening box 4, and on the other hand, in cooperation with the vibration motor 8, it can drive the screening box 4 to vibrate repeatedly.
[0033] During the screening of the aggregate, the vibration motor 8 can also be turned on. When the vibration motor 8 cooperates with a number of support assemblies 3, it can drive the screening box 4 to vibrate, so that the screening box 4 can drive the aggregate on the screen mesh 5 to vibrate, enabling the aggregate to move slowly towards the hopper 12 during vibration, and enabling some of the aggregate to fall from the hopper 12.
