[0033] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0034] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0035] like Figure 1-7As shown, an anti-blocking environmentally friendly brick raw material screening equipment comprises: a support frame 2 equipped with a plurality of support legs 1, a movable frame 4 whose inclined lower end is rotatably connected to one end of the support frame 2 through a horizontal rotating shaft 3, a plurality of horizontal support rods 5 arranged at equal intervals along the inclined direction of the movable frame 4 and all mounted on the movable frame 4, a vibration unit mounted on the end of the support frame 2 away from the rotating shaft 3 for driving the movable frame 4 to reciprocate, and a cleaning unit mounted on the lower surface of the movable frame 4;

[0036] The movable frame 4 is equipped with a pair of material blocking side plates 6 arranged at intervals along the length direction of the support rods 5 and in contact with the upper surfaces of several support rods 5 through the first mounting frame. The cleaning unit includes a cleaning cylinder 7 with a bearing 17 parallel to the axis of the support rods 5 and a driving mechanism installed on the lower surface of the movable frame 4 for driving the cleaning cylinder 7 to roll along the tilting direction of the movable frame. On the outer surface of the cleaning cylinder 7, several ejecting strips 8 are protruded in the same length direction and are evenly distributed in the circumferential direction and can be respectively inserted between the corresponding two support rods 5. The upper surface of the support rod 5 is arc-shaped.

[0037] In the above technical solution, the raw materials are delivered to a plurality of support rods 5 at the upper end of the movable frame 4. During the vibration process in which the vibration unit drives the movable frame 4 to rotate reciprocatingly, the raw materials that meet the specifications will fall from the space between two adjacent support rods 5, and the raw materials that do not meet the specifications will move along the inclined direction of the movable frame 4, and finally fall from the inclined lower end of the movable frame 4.

[0038] During cleaning, the driving mechanism drives the cleaning cylinder 7 to roll along the movable frame 4, so that the ejecting strip 8 is inserted upward between the two corresponding adjacent support rods 5, so that the stuck raw materials can be ejected upward. When the equipment is started, the ejected raw materials will move along the inclined direction of the movable frame 4, and finally fall from the lower end of the movable frame 4.

[0039] The upper surface of the support rod 5 is arc-shaped, so that the support rod 5 has the effect of slowing down the speed of the raw materials moving toward the lower end of the movable frame 4, so that the raw materials that meet the specifications have enough time to fall downward from between two adjacent support rods 5.

[0040] When the screening equipment is working normally, the cleaning cylinder 7 is located at the supporting lower end of the movable frame 4, because the raw materials that meet the specifications have fallen from the space between any two adjacent support rods 5, so as to avoid the accumulation of the fallen raw materials on the cleaning cylinder 7.

[0041] The cleaning unit can be started when the equipment is in the screening process, so that the cleaning unit can clean the raw materials stuck between two adjacent support rods 5 while the screening is in progress, and can also be cleaned when the screening is stopped.

[0042] In a preferred embodiment of the invention, the driving mechanism includes a first connecting shaft 9 coaxially assembled on the cleaning barrel 7, a pair of strip slides 10 respectively assembled on the two inclined sides of the movable frame 4 in the same length direction, a pair of sliders 11 respectively slidably assembled on the corresponding strip slides 10, a pair of first shaft seats respectively connected to the two ends of the first connecting shaft 9 and respectively assembled on the corresponding sliders 11, a first motor 12 assembled on one of the sliders 11 and with the output shaft connected to one end of the first connecting shaft 9, a rack 13 assembled on the inclined side of the movable frame 4 in the same length direction, and a first gear 14 fixedly sleeved on the first connecting shaft 9 and meshing with the rack 13.

The sliding member 20 slides on the guide arm 19, and the threaded sleeve 16 drives the cleaning block 18 to move through the bearing 17. The cleaning block 18 moves along the axial direction of the threaded rod 15 to clean the raw materials attached to the cleaning block. When the cleaning barrel 7 rotates, the cleaning barrel 7 will also drive the cleaning block 18 to rotate, so that the cleaning groove can be sleeved on the corresponding top material strip 8. When the cleaning barrel 7 rolls back and forth once along the movable frame 4, the threaded sleeve 16 also reciprocates once.

[0047] In a preferred embodiment of the invention, the two inclined sides of the movable frame 4 are equipped with a plurality of mounting sleeves 23 for the ends of the corresponding support rods 5 to pass through, and the ends of the support rods 5 are equipped with detachable limiting rings 24.

[0048] In the above technical solution, the limiting ring 24 is disassembled to facilitate the replacement of the support rod 5.

[0052] In the above technical solution, the spring 28 pushes the movable frame 4 to rotate downward, so that the pulley 29 contacts the cam 31, and the second motor 32 drives the cam 31 to rotate through the second connecting shaft 30. When the cam 31 rotates, it pushes the pulley 29 to move upward, thereby driving the movable frame 4 to rotate upward, realizing the reciprocating rotation of the movable frame 4 around the rotating shaft 3.

[0053] In a preferred embodiment of the invention, the inclined upper end of the material-blocking side plate 6 is equipped with a material-blocking top plate 33 fixedly connected to another material-blocking side plate 6 .
