Description

Technical Field

[0001] The present invention relates to the technical field of manufactured sand production, and particularly to a manufactured sand production device. Background Art

[0002] Manufactured sand refers to sand processed by a sand making machine and other auxiliary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different technological requirements, which can better meet daily needs. The production process of manufactured sand includes: raw material mining, raw material crushing (coarse crushing, medium crushing, and fine crushing), screening, sand making, sand washing, etc. A manufactured sand production line is composed of equipment such as a vibrating feeder, a jaw crusher, a sand making machine, a vibrating screen, and a belt conveyor.

[0003] However, when screening the crushed manufactured sand raw materials, the mutual extrusion and collision between the screening materials cause some to be compacted in the screen holes of the screen, resulting in the blockage of the screen and affecting the screening efficiency and effect of the screening materials; therefore, it does not meet the existing requirements, and for this reason, we propose a manufactured sand production device. Summary of the Invention

[0004] The purpose of the present invention is to provide a manufactured sand production device to solve the problems mentioned in the above background art, that is, when screening the crushed manufactured sand raw materials, the mutual extrusion and collision between the screening materials cause some to be compacted in the screen holes of the screen, resulting in the blockage of the screen and affecting the screening efficiency and effect of the screening materials.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A manufactured sand production device includes an equipment frame and a fine material collection funnel. The fine material collection funnel is located above the equipment frame. A screen structure is detachably installed on the upper surface of the fine material collection funnel. The screen structure includes a screen plate fixing frame. The bottom surface of the screen plate fixing frame is in contact with the upper surface of the fine material collection funnel. A screen plate is fixed inside the screen plate fixing frame. A plurality of screen holes are distributed in a rectangular array on the surface of the screen plate. A dredging structure is arranged above the screen plate; The dredging structure includes two symmetrically distributed electric telescopic rods. The two electric telescopic rods are fixed on the outside of the screen plate fixing frame. Sliding strips are fixed at the movable ends of the two electric telescopic rods. A plurality of mutually parallel support rods are fixed between the two sliding strips. A plurality of hanging metal plates are linearly distributed on the outside of the support rods. One end of the hanging metal plate is fixed with a dredging metal plate. The bottom end of the dredging metal plate is located inside the screen hole.

[0006] Preferably, the equipment frame includes a fixed seat, two vibration motors are fixed at the top end of the fixed seat, four guide rods are fixed on the upper surface of the fixed seat, guide plates are fixed at the four end corners of the fine material collection funnel, the guide plates are penetrated by the guide rods, support plates are fixed on two sides of the fine material collection funnel, and the output shaft of the vibration motor is fixedly connected with the support plate.

[0007] Preferably, the hanging metal plate is bent in a U shape with both ends facing downwards, one end of the hanging metal plate is fixed to the dredging metal plate, and the other end of the hanging metal plate is bent inwards at a right angle.

[0008] Preferably, a return spring is arranged between the bent end of the hanging metal plate and the support rod, and a cylindrical protrusion is arranged at the end of the hanging metal plate in contact with the return spring.

[0009] Preferably, the bottom end of the dredging metal plate is bent upwards at an angle of 15 degrees, and a buffer metal sheet is fixed on the upper surface of the bent bottom end of the dredging metal plate.

[0010] Preferably, one end of the sieve hole is a slope inclined at an angle of 45 degrees, the other end of the sieve hole is provided with a sliding groove, and an anti - detachment sliding groove is arranged on the bottom surface of the sliding groove.

[0011] Preferably, a shielding slide plate is slidably installed inside the sliding groove, an anti - detachment slider is fixed to the bottom surface of the shielding slide plate, the cross - section of the anti - detachment slider is T - shaped, and the anti - detachment slider is slidably clamped inside the anti - detachment sliding groove.

[0012] Preferably, three storage holes are arranged at one end of the shielding slide plate, and a top - out spring is arranged inside the storage holes.

[0013] Preferably, both ends of the top - out spring are fixedly connected with the shielding slide plate and the sieve plate respectively, and the free length of the top - out spring is less than the length of the shielding slide plate.

[0014] Preferably, the end of the shielding slide plate in contact with the sieve plate is an inclined slope, and the inclination angle of the slope is 30 degrees.

[0015] After the electric telescopic rod is powered on and starts, it pushes the sliding bar to slide. After the sliding bar is pushed, the bottom - end support rod and the hanging metal plate move. The moved hanging metal plate drives the dredging metal plate to move simultaneously. When the dredging metal plate moves, the buffer metal sheet first contacts the fine material blocked inside the sieve hole and applies an obliquely upward thrust to the fine material from below the fine material, so that the fine material blocked inside the sieve hole rolls inside the sieve hole until the fine material rolls out from the inside of the sieve hole along the slope at the end of the sieve hole, realizing the dredging of the sieve hole, thereby ensuring that the screening rate and screening effect of the subsequent fine material during screening will not decrease.

[0016] When the dredging metal plate moves and dredges the fine materials blocked inside the sieve holes, the ejecting spring elastically restores and pushes the shielding slide plate to slide inside the sliding groove, so that one end of the shielding slide plate always fits with the moving dredging metal plate, thereby preventing the fine materials dredged from the sieve holes from entering another sieve hole, and ensuring that the reset action of the dredging metal plate is not hindered.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0020] Such as Figure 1As shown in the figure, a mechanism sand production device provided by the present invention includes an equipment frame 1 and a fine material collection funnel 2. The fine material collection funnel 2 is located above the equipment frame 1. The equipment frame 1 includes a fixed seat. At the top end of the fixed seat, two vibration motors are fixed. On the upper surface of the fixed seat, four guide rods are fixed. At the four end corners of the fine material collection funnel 2, guide plates are fixed. The guide plates are penetrated by the guide rods. On two sides of the fine material collection funnel 2, support plates are fixed. The output shafts of the vibration motors are fixedly connected to the support plates.

[0021] As Figure 2 , Figures 4 - 6 and Figure 8 shown, a screen structure 3 is detachably installed on the upper surface of the fine material collection funnel 2. The screen structure 3 includes a screen plate fixing frame 301. The bottom surface of the screen plate fixing frame 301 contacts the upper surface of the fine material collection funnel 2. Inside the screen plate fixing frame 301, a screen plate 302 is fixed. On the surface of the screen plate 302, a plurality of screen holes 303 are distributed in a rectangular array. One end of the screen hole 303 is an inclined surface with a 45-degree angle. At the other end of the screen hole 303, a sliding groove 305 is provided. At the bottom surface of the sliding groove 305, an anti-disengagement sliding groove 306 is provided. The inclined surface at the end of the screen hole 303 facilitates the removal of the fine material blocking the screen hole 303 when the dredging metal plate 405 moves, reducing the dredging difficulty of the dredging metal plate 405 for the screen hole 303.

[0022] A shielding sliding plate 304 is slidably installed inside the sliding groove 305. At the bottom surface of the shielding sliding plate 304, an anti-disengagement slider 307 is fixed. The cross-section of the anti-disengagement slider 307 is T-shaped, and the anti-disengagement slider 307 is slidably clamped inside the anti-disengagement sliding groove 306. The position of the shielding sliding plate 304 is restricted by the anti-disengagement slider 307 to ensure that the shielding sliding plate 304 will not fall off the surface of the screen plate 302 during the operation of the device.

[0023] At one end of the shielding sliding plate 304, three storage holes are provided. Inside the storage holes, a top spring 308 is provided. The two ends of the top spring 308 are respectively fixedly connected to the shielding sliding plate 304 and the screen plate 302. The free length of the top spring 308 is less than the length of the shielding sliding plate 304. After the dredging metal plate 405 moves along with the support rod 402 and the hanging metal plate 403, the top spring 308 elastically restores and the bottom end of the shielding sliding plate 304 slides inside the sliding groove 305. During this process, one end of the shielding sliding plate 304 always fits with the dredging metal plate 405, ensuring that the fine material taken out from the screen hole 303 will not enter the space between the moved dredging metal plate 405 and the screen hole 303, thus ensuring that the reset action of the dredging metal plate 405 will not be adversely affected.

[0024] The end of the shielding slide plate 304 in contact with the sieve plate 302 is an inclined slope surface, and the inclination angle of the slope surface is 30 degrees. During the reset process of the shielding slide plate 304, the inclined slope surface at the end of the shielding slide plate 304 can separate the bottom of the fine material entering the inner side of the sliding groove 305 from the sliding groove 305, so that the reset action of the shielding slide plate 304 will not be affected.

[0025] As Figure 2 , Figure 3 , Figure 7 and Figure 8 shown, a dredging structure 4 is provided above the sieve plate 302. The dredging structure 4 includes two symmetrically distributed electric telescopic rods 404. The two electric telescopic rods 404 are fixed on the outside of the sieve plate fixing frame 301. Sliding bars 401 are fixed to the movable ends of the two electric telescopic rods 404. A plurality of parallel support rods 402 are fixed between the two sliding bars 401. A plurality of hanging metal plates 403 are linearly arrayed on the outside of the support rods 402. One end of the hanging metal plate 403 is fixed with a dredging metal plate 405. The bottom end of the dredging metal plate 405 is located inside the sieve hole 303. By using the electric telescopic rod 404 to push the sliding bar 401 to slide on the outside of the sieve plate fixing frame 301, the bottom end of the sliding bar 401, the support rod 402 and the hanging metal plates 403 on the outside of the support rod 402 are moved, so that the bottom end of the dredging metal plate 405 slides inside the sieve hole 303, separating the fine material stuck in the sieve hole 303, realizing the dredging of the sieve hole 303, and avoiding the reduction of the subsequent screening efficiency and screening speed of the fine material.

[0026] The hanging metal plate 403 is U-shaped bent and both ends face downwards. One end of the hanging metal plate 403 is fixed to the dredging metal plate 405, and the other end of the hanging metal plate 403 is bent inwards at 90 degrees. The U-shaped bent hanging metal plate 403 will not slide on the outside of the support rod 402. When the hanging metal plate 403 is subjected to an upward force, the hanging metal plate 403 can fit on the outer surface of the support rod 402 and slide upwards.

[0027] A return spring 407 is provided between the bent end of the hanging metal plate 403 and the support rod 402. A cylindrical protrusion is provided at the end of the hanging metal plate 403 in contact with the return spring 407, ensuring that the return spring 407 will not fall from between the hanging metal plate 403 and the support rod 402. After the support rod 402 is reset, the return spring 407 ensures that the hanging metal plate 403 can be reset simultaneously.

[0028] The bottom end of the dredging metal plate 405 is bent upward at an angle of 15 degrees. A buffer metal sheet 406 is fixed on the upper surface of the bent bottom end of the dredging metal plate 405. The bent bottom end of the dredging metal plate 405 can exert force on the fine material at the bottom of the fine material blocked in the sieve hole 303, so as to better dredge the fine material blocked in the sieve hole 303. When the fine material is dredged, the buffer metal sheet 406 impacts with the fine material, applies an upward force to the fine material that has entered the sieve hole 303 but has not fallen, and delays the blockage of the sieve hole 303 by the fine material.

[0029] When the mechanism sand production device provided by the present invention is specifically used, first connect the power supply of the device. After the power supply is connected, the two vibration motors are started simultaneously, so that the fine material collection funnel 2, the sieve structure 3 and the dredging structure 4 vibrate. At this time, the fine material formed after the raw material is finely crushed is added to the surface of the sieve plate 302. As the sieve plate 302 continuously vibrates, the fine material passes through the sieve holes 303 distributed in a rectangular array on the surface of the sieve plate 302 and enters the inside of the fine material collection funnel 2. The screened fine material leaves the fine material collection funnel 2 from the bottom of the fine material collection funnel 2 and is collected by the staff, completing the screening of the fine material. After the screening of the fine material is completed and the screening of other fine materials is carried out, it is necessary to dredge the sieve holes 303 to avoid the blockage of the sieve holes 303, which leads to the reduction of the subsequent screening rate and the screening effect. When dredging the sieve holes 303, connect the power supply of the two electric telescopic rods 404 and start them. After the electric telescopic rod 404 is started, its movable end extends and pushes the sliding bar 401. After the sliding bar 401 is pushed, the bottom support rod 402 and the hanging metal plate 403 move, and the moved hanging metal plate 403 drives the dredging metal plate 405 to move at the same time. When the dredging metal plate 405 moves, the buffer metal sheet 406 first contacts the fine material blocked inside the sieve hole 303 and applies an obliquely upward thrust to the fine material from below the fine material, so that the fine material blocked inside the sieve hole 303 rolls inside the sieve hole 303 until the fine material rolls out of the inside of the sieve hole 303 along the inclined surface at the end of the sieve hole 303, realizing the dredging of the sieve hole 303, so as to ensure that the screening rate and screening effect of the subsequent fine material during screening will not decrease.

[0030] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
