For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] A vibrating screen according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A vibrating screen according to an embodiment of the utility model includes a screening mechanism and a blockage clearing mechanism.

[0031] As for the screening mechanism, the screening mechanism includes a silo 100, a screen 110 arranged in the silo 100, and a vibrator 120 located on the silo 100 and driving the silo 100 to vibrate. A feed port 130 is arranged at the top of one side of the silo 100, and a discharge port 140 is arranged on the other side of the silo 100. The screen 110 is located below the feed port 130 and between the discharge port 140. The screen 110 is arranged to be inclined downward from the feed port 130 to the discharge port 140. A first material tray 150 is arranged below the screen 110, and the first material tray 150 is used to receive the qualified soy sauce dregs screened by the screen 110. A second material tray 160 is arranged below the discharge port 140, and the second material tray 160 is used to receive the unqualified soy sauce dregs screened by the screen 110.

[0032] It can be understood that the soy sauce dregs enter the silo 100 from the feed port 130 and fall on the screen 110. At the same time, the vibrator 120 drives the silo 100 to vibrate, so that the silo 100 drives the screen 110 to vibrate, and the soy sauce dregs on the screen 110 automatically roll toward the discharge port 140 along the inclination direction of the screen 110 as the screen 110 vibrates. In the process of the soy sauce dregs rolling on the screen 110, the soy sauce dregs that are crushed to the qualified level fall from the mesh holes of the screen 110 to the first material tray 150, and the soy sauce dregs that are unqualified cannot pass through the mesh holes of the screen 110, thereby causing the soy sauce dregs that are unqualified to fall from the discharge port 140 to the second material tray 160, and further, the vibrating screen can screen and separate the soy sauce dregs that are crushed to the qualified level and the unqualified level, so as to facilitate the screening out of the unqualified soy sauce dregs for re-crushing.

[0033] Specifically, the screen 110 includes a frame and a mesh embedded in the frame. The frame is used to be installed on the silo 100, and the mesh is used to filter and screen the soy sauce dregs, so that the frame can tension the mesh.

[0034] In some specific embodiments, a top cover 200 is provided on the top of the silo 100, and the top cover 200 is arranged parallel to the screen 110. The first cylinder 170 is fixed on the top cover 200, so that the top cover 200 can support the first cylinder 170, making the first cylinder 170 more stable.

[0035] In some specific embodiments, the vibrator 120 is disposed on the top cover 200 , so that the top cover 200 can support the vibrator 120 , so that the vibrator 120 can transmit vibration to the screen 110 through the top cover 200 and the silo 100 .

[0036] In some specific embodiments, the top cover 200 and the silo 100 are fixed by welding or bolting, so that the connection between the top cover 200 and the silo 100 is more secure.

[0037] In some specific embodiments, the screening mechanism further includes a frame 220 , and a side of the silo 100 close to the feed port 130 is hinged to the frame 220 , and the silo 100 swings up and down to adjust the inclination angle of the screen 110 .

[0038] It is understandable that by adjusting the inclination angle of the screen 110, the rolling speed of the soy sauce dregs on the screen 110 can be adjusted, thereby facilitating the adjustment of the screening speed of the vibrating screen.

[0039] In some specific embodiments, an adjustment assembly 230 is further provided between the frame 220 and the silo 100, and the adjustment assembly 230 includes a first mounting seat 240, a second mounting seat 250 and a first screw 260. The first mounting seat 240 is hinged to the frame 220, the second mounting seat 250 is hinged to the silo 100, the first screw 260 is rotatably connected to one of the first mounting seat 240 and the second mounting seat 250, and the first screw 260 is threadedly connected to the other of the first mounting seat 240 and the second mounting seat 250. The first screw 260 rotates to drive the silo 100 to swing up and down.

[0040] It can be understood that by rotating the first screw 260, the first mounting seat 240 and the second mounting seat 250 are moved closer to and away from each other. At the same time, the first mounting seat 240 is hinged to the frame 220, and the second mounting seat 250 is hinged to the silo 100, so that the first screw 260 can drive the silo 100 to swing up and down along the hinge center of the silo 100 and the frame 220, and then, the inclination angle of the screen 110 can be quickly adjusted. In addition, since the first screw 260 is rotatably connected to one of the first mounting seat 240 and the second mounting seat 250, the first screw 260 is threadedly connected to the other of the first mounting seat 240 and the second mounting seat 250. Therefore, when the first screw 260 is not driven to rotate by external force, the threaded connection between the first screw 260 and the first mounting seat 240 and the second mounting seat 250 can be self-locking, which is convenient for fixing the silo 100, and then, it is convenient to fix the inclination angle of the screen 110.

[0041] Furthermore, a hand wheel 270 is provided at one end of the first screw rod 260 , so that the first screw rod 260 can be rotated conveniently by the hand wheel 270 , thereby making the rotation operation of the first screw rod 260 more convenient.

[0042] In some specific embodiments, the screening mechanism also includes a frame 220, the frame 220 includes a base frame 280, a mounting frame 290, and a spring 300 arranged between the base frame 280 and the mounting frame 290, and the silo 100 is installed on the mounting frame 290, so that the spring 300 can support the vibration of the silo 100.

[0043] In some specific embodiments, a side of the silo 100 close to the feed port 130 has a first chute 310 extending obliquely downward, and the first chute 310 accommodates the screen 110 , thereby facilitating the installation and positioning of the screen 110 in the silo 100 .

[0044] Furthermore, a pull ring 320 is provided at one end of the screen 110, and the pull ring 320 abuts and limits the outer side of the silo 100. On the one hand, the pull ring 320 abuts and limits the outer side of the silo 100, so that the installation position of the screen 110 in the first slide groove 310 is more precise. On the other hand, the pull ring 320 can pull the screen 110 away from the first slide groove 310, thereby making it easier to disassemble the screen 110.

[0045] As for the blockage clearing mechanism, the blockage clearing mechanism includes a first cylinder 170 fixedly arranged on the top of the silo 100, a mounting plate 180 of the telescopic rod arranged on the first cylinder 170, and a plurality of needles 190 arranged on the bottom of the mounting plate 180. One needle 190 corresponds to one mesh hole on the screen 110. The first cylinder 170 drives the mounting plate 180 to rise and fall so that the needles 190 penetrate into the mesh holes of the screen 110 to clear the blockage.

[0046] It can be understood that when the screen 110 needs to be unblocked, the first cylinder 170 drives the mounting plate 180 to descend, so that the mounting plate 180 drives a number of needles 190 to descend and insert into the meshes of the screen 110, so that the needles 190 can remove the soy sauce residue blocked in the meshes of the screen 110. After the needles 190 complete cleaning of the soy sauce residue blocked in the meshes of the screen 110, the first cylinder 170 drives the mounting plate 180 to rise, so that the mounting plate 180 drives the needles 190 to detach from the meshes of the screen 110 to avoid the soy sauce residue on the screen 110, thereby enabling the vibrating screen to quickly clear the blockage of the screen 110 and maintain the screening efficiency.

[0047] In some specific embodiments, the bottom end of the needle 190 has a tapered portion 210, which is used to guide the needle 190 into the mesh of the screen 110, so that the tapered portion 210 can guide the needle 190 to be inserted into the mesh of the screen 110, thereby making it easier for the needle 190 to be inserted into the mesh of the screen 110, thereby avoiding collision between the needle 190 and the screen 110 and damaging the needle 190.

[0048] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
