Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of separation devices, in particular to a concrete sand and stone separation device. Background Art
[0002] Concrete refers to a general term for engineering composite materials in which aggregate is cemented into a whole by a cementitious material. Usually, the term concrete refers to portland cement concrete, also known as ordinary concrete, which is made of cement as the cementitious material, sand and stone as the aggregate, and water (which may contain additives and admixtures) in a certain proportion and is obtained by stirring. It is widely used in civil engineering. When preparing concrete, sand is needed, but a certain amount of stones are mixed in the sand, and these stones need to be screened and separated.
[0003] When screening sand, sand screening equipment is used. The sand enters the screening equipment through a hopper. Since the weight of the stones is heavier than that of the sand, the stones sometimes get stuck between the hopper and the screen, which will reduce the screening efficiency of the sand and the stones. In view of this, a concrete sand and stone separation device is designed. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that in the prior art, since the weight of the stones is heavier than that of the sand, the stones sometimes get stuck between the hopper and the screen, which will reduce the screening efficiency of the sand and the stones.

Specific embodiments
[0022] 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 without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Refer to Figure 1 and Figure 2 , a concrete sand and gravel separation device includes a bottom frame 1. A slantingly arranged screening frame 2 is fixedly connected to the top of the bottom frame 1. A screening mesh 3 is fixedly connected inside the screening frame 2. Support rods 4 are fixedly connected to the four corners of the top of the screening frame 2. The tops of the four support rods 4 are connected to a top frame 6 through an adjustment assembly 5. A first hopper 7 is fixedly connected inside the top frame 6. The cross-section of the first hopper 7 is trapezoidal. The top area of the first hopper 7 is smaller than its bottom area. The bottom of the first hopper 7 is located inside the screening frame 2.
[0024] Refer to Figure 3 , the adjustment assembly 5 includes a first ear 501 and a second ear 502. The first ear 501 is fixedly connected to the top of the support rod 4. The second ear 502 is fixedly connected to the bottom of the support leg of the top frame 6. The top of the first ear 501 is rotatably connected to a threaded rod 503. The top of the threaded rod 503 passes through the top of the second ear 502. A through threaded hole is opened at the top of the second ear 502. The external threaded part of the threaded rod 503 is connected to the internal threaded part of the threaded hole. A handwheel 505 is fixedly connected to the top of the threaded rod 503. A locking nut 504 is threadedly sleeved on the outer surface of the threaded rod 503. The bottom of the locking nut 504 abuts against the top of the second ear 502. When sand and gravel enter the screening frame 2 through the first hopper 7, if stones are blocked between the first hopper 7 and the screening mesh 3, rotate the handwheels 505 simultaneously, which can drive the threaded rod 503 to rotate, drive the top frame 6 to move up and down through the second ear 502, and then adjust the distance between the first hopper 7 and the screening mesh 3, facilitating the flattening and sorting of the stones and improving the efficiency of sand and gravel screening.
[0025] Referring to Figure 1 and Figure 4 On the outside of the bottom frame 1, a vibration motor 8 is fixedly connected. At the four corners of the screening frame 2, first fixing plates 9 are fixedly connected, and at the four corners of the top of the bottom frame 1, second fixing plates 11 are fixedly connected. A buffer spring 10 is fixedly connected between the first fixing plate 9 and the second fixing plate 11. Through the buffer spring 10, the vibration effect of the screening frame 2 can be improved, and the efficiency of sand and gravel screening is improved.
[0026] Referring to Figure 1 and Figure 2 Inside the bottom frame 1, an inclined hopper 12 is fixedly connected, and the top of the inclined hopper 12 is located at the bottom of the screening frame 2. On the outside of the bottom frame 1, a discharge pipe 13 is fixedly connected, and one end of the discharge pipe 13 is connected to the lowest end of the inclined hopper 12. When the vibration motor 8 operates, the screening frame 2 generates vibration. Through the screening mesh 3, the stones in the sand material can be screened out. The sand material falls from the screening mesh 3 into the inclined hopper 12 and is discharged through the discharge pipe 13. Since the screening frame 2 is inclined, the stones will roll to the lowest end on the top of the screening mesh 3 and be discharged, which is convenient for the separation of sand and gravel.
[0027] On one side of the bottom frame 1, a second hopper 15 is fixedly connected through a support frame 14, and the second hopper 15 is lapped at the highest end of the screening mesh 3. Through the second hopper 15, the sand material can be discharged to the highest position of the screening mesh 3, which is further convenient for the sand and gravel screening operation.
[0028] Working principle: When in use, the vibration motor 8 operates to make the screening frame 2 vibrate. Through the screening mesh 3, the stones in the sand material can be screened out. The sand material falls from the screening mesh 3 into the inclined hopper 12 and is discharged through the discharge pipe 13. Since the screening frame 2 is inclined, the stones will roll to the lowest end on the top of the screening mesh 3 and be discharged, and the sand and gravel screening operation is carried out;
[0029] When the sand material enters the screening frame 2 through the first hopper 7, if the stones are blocked between the first hopper 7 and the screening mesh 3, rotate the handwheels 505 simultaneously, which can drive the threaded rod 503 to rotate, drive the top frame 6 to move up and down through the second ear 502, and then adjust the distance between the first hopper 7 and the screening mesh 3, and the stones can be flattened and sorted out.
[0030] It should be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
