Description

[0002] As we all know, in the process of underground tunnel construction, shield machines are used to excavate underground soil or rock layers, and the excavated gravel is transported to the surface by belt conveyors. In order to reuse the gravel, sorting equipment is used to sort the gravel, and gravel of different sizes is screened out for secondary use.
[0003] Among them, when sorting gravel for sorting equipment, multiple sorting mechanisms will be set up, and the most important part of each sorting mechanism is its sieve plate component, that is, the sieve plate component is used to screen the gravel. At present, most of the existing sieve plates are integrated with the main frame, and when screening, they only rely on the vibration generated by the main frame to be transmitted to the sieve plate, so that the gravel on the sieve plate can achieve the screening effect during the vibration process. However, this setting relies too much on the vibration frequency transmitted by the main frame. If the vibration frequency transmitted by the main frame is not enough, it is easy to cause insufficient screening of gravel, resulting in large-sized gravel mixed with fine gravel that should be screened out.

[0022] like Figures 1 to 6As shown, the sieve plate component of a sand sorting equipment provided in the present embodiment comprises a driven sieve plate 1, a swinging sieve plate 2, a screening bin 3 and a power assembly 4 arranged on a main frame, the surfaces of the driven sieve plate 1 and the swinging sieve plate 2 are both provided with a sieve mesh 10, one end of the driven sieve plate 1 and the swinging sieve plate 2 is provided with a first overlapping portion 11 that rises upward, the other end of the driven sieve plate 1 and the swinging sieve plate 2 is provided with a second overlapping portion 12 that extends downward, the first overlapping portion 11 of the swinging sieve plate 2 overlaps with the second overlapping portion 12 of the driven sieve plate 1, the second overlapping portion 12 of the swinging plate 2 overlaps with the first overlapping portion 11 of another driven sieve plate 2, so that the driven sieve plate 1 and the swinging sieve plate 2 are overlapped alternately head to tail, there is an active gap between the first overlapping portion 11 and the second overlapping portion 12, both ends of the driven sieve plate 1 are installed in the screening bin 3, and the screening bin 3 is provided at the position of the swinging sieve plate 2. A pair of sockets 21 are provided, and at least three spring top beads 22 arranged in a circular array are provided in the pair of sockets 21. Shafts 23 are provided at both ends of the swing screen plate 2. The shafts 23 are inserted in the pair of sockets 21, and the round beads of the spring top beads 22 touch the shafts 23, so that the shafts 23 can move in the pair of sockets 21. The ends of the shafts 23 are placed outside the screening bin 3 and are provided with a force plate 24. The shafts 23 on the same side are connected to the same force plate 24. A first spring 25 is provided between the force plate 24 and the outer wall of the screening bin 3. The power assembly 4 includes at least two rotating motors 41 respectively provided at both ends of the force plate 24. A rotating member 42 is provided on the optical axis of the rotating motor 41. At least one slapping block 43 is provided on the rotating member 42. Under the drive of the rotating motor 41, a single slapping block 43 pushes the force plate 24 once per rotation.
[0023] Among them, the driven sieve plate 1 and the swing sieve plate 2 are arranged in a stepped manner in the screening bin 3, and the driven sieve plate 1 and the swing sieve plate 2 are arranged at an angle, so that there is an oblique angle between the plate surface of the driven sieve plate 1 and the swing sieve plate 2 and the horizontal plane, and the oblique angle can be set to 30°, and a movable space is provided between the side edges of the driven sieve plate 1 and the swing sieve plate 2 and the inner wall of the screening bin 3.
[0024] In this embodiment, the sieve plate is designed to be split, and a force is provided at one of the swinging sieve plates 2 to cause the swinging sieve plate 2 to swing left and right, so that a left and right vibration force is added to the sand sorting equipment, thereby further accelerating the sand and gravel sorting rate, so that the sand and gravel screening can be effectively completed in a limited screening area; at the same time, the layout adopts an inclined and stepped layout, so that during the vibration transmission process, the sand and gravel can fall freely when falling from a high ground, so that some sand and fine gravel can automatically pass through the sieve mesh 10, thereby once again improving the efficiency of sand and gravel screening.
[0025] When the gravel screening work is carried out specifically, the rotating motor 41 will be energized and rotated. After the rotation, the beating block 43 on the rotating part 42 will rotate and then beat the force plate 24. After the beating force, the force plate 24 will push the force plate 24 inward, and the first spring 25 located at the force plate 24 will be compressed. A spring top bead 22 is set between the shaft rod 23 of the swinging screen plate 2 and the socket 21. Therefore, after the force plate 24 is pushed by the force, the swinging screen plate 2 will also move accordingly. When the beating block 43 continues to rotate and disengages from the force plate 24, under the reaction of the first spring 25, the force plate 24 will rebound to the initial position, waiting for the next beating block 43 to beat. Repeated operations in multiple places will cause the swinging screen plate 2 to swing left and right. When the gravel is discharged from the hopper into the screening bin 3, that is, discharged on the driven screen plate 1 or the swinging screen plate 2, and the swinging screen plate 2 adds a left and right swinging action, the screening force can be further strengthened. Among them, the width of the plate surface of the force-bearing plate 24 must meet the requirement that the beating block can always hit the force-bearing plate when the sorting equipment itself vibrates. Therefore, the width of the force-bearing plate cannot be too small, and it needs to be coordinated with the vibration amplitude of the sorting equipment.
[0026] Furthermore, in order to enhance the screening strength and efficiency, the driven screen plate 1 and the screening bin 3 of this embodiment are installed in a plug-in manner, so that the driven screen plate 1 can move left and right, wherein the first overlap portion 11 is provided with a limit block 13, the second overlap portion 12 is provided with a docking groove 14, the limit block 13 is placed in the docking groove 14, and two second springs 15 are provided in the docking groove 14, and the two second springs 15 are respectively in contact with the two side ends of the limit block 13. Therefore, after the swing screen plate 2 swings, it will drive the driven screen plate 1 to swing left and right, forming a linkage, so that no matter which screen plate the gravel is on, the left and right swinging screening action can be added.
[0027] Furthermore, with regard to the specific installation method of the driven screen plate 1, round rods 16 are provided at both ends of the driven screen plate 1, and a shaft sleeve 31 is provided on the screening bin 3. The round rod 16 of the driven screen plate 2 is inserted into the shaft sleeve 31, thereby satisfying the plug-in installation between the driven screen plate 1 and the screening bin 3.
[0028] Furthermore, a shielding plate 17 is provided at the bottom of the second overlapping portion 12 of the present embodiment. The shielding plate 17 can prevent fine sand and gravel from falling into the movable gap between the first overlapping portion 11 and the second overlapping portion 12.
[0029] Furthermore, because there are gaps or movable spaces between the driven sieve plate 1 and the swing sieve plate 2 and the inner walls of the screening bin 3, in order to prevent gravel from falling from there, baffles 18 are vertically set on the edges of both sides of the driven sieve plate 1 and the swing sieve plate 2 in this embodiment.
[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
