[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] Combine the following Figures 1 to 4 The utility model is described in detail.
[0023] A feed pretreatment screening device includes a base 1, a support frame 101 is arranged on the top of the base 1, a screening box 2 is arranged on the top of the support frame 101, a discharge port 201 is arranged at the bottom of the screening box 2, a screening net 202 is connected to the inside of the screening box 2, an overlapping net 203 is connected to the bottom of the screening net 202, sliders 2032 are arranged on both sides of the overlapping net 203, an adjusting component is connected to the top of the overlapping net 203 near one side, the adjusting component penetrates the overlapping net 203 to the top, the overlapping net 203 and the adjusting component are transmission-coordinated, the overlapping net 203 is a mesh plate fitted at the bottom of the screening net 202, and the holes of the overlapping net 203 are consistent with those on the screening net 202.
[0024] First, pour the feed to be pretreated into the screening box 2, and then slide along the screening net 202 in the screening box 2. During the sliding process, the feed will fall through the holes of the screening net 202 and be discharged and collected through the discharge port 201, while some larger impurities will slide directly to the other end through the screening net 202 and be discharged, thereby pre-treating and screening the feed.
[0025] Furthermore, the adjustment component includes a displacement groove 2031, an adjustment rod 204, a toothed ring 2041 and a limiting stop 2042. The displacement groove 2031 is arranged at the top of one side of the overlapping net 203, the adjustment rod 204 is arranged in the middle of the displacement groove 2031, the toothed ring 2041 is arranged at the side wall of the adjustment rod 204 near the bottom, and the limiting stop 2042 is arranged on both sides of the adjustment rod 204 near the top. The displacement groove 2031 is a groove arranged at the top of one side of the overlapping net 203, and a toothed ring 2041 is arranged on one side of the middle of the displacement groove 2031. The adjusting rod 204 is a rod body connected to the middle of the displacement groove 2031, and the top part of the adjusting rod 204 penetrates and protrudes from the top of the screening net 202. The tooth ring 2041 is meshed with the rack on one side of the middle of the displacement groove 2031. The width of the tooth ring 2041 is greater than the rack. The limiting stop 2042 is a block connected to the grooves on both sides of the adjusting rod 204 near the top through a hinge shaft at one end. The hinge shaft at one end of the limiting stop 2042 is connected through torsion springs at both ends, and the side wall of the limiting stop 2042 away from the hinge shaft is provided with anti-slip grooves.
[0026] At the same time, when pre-treatment screening is performed through the screening net 202, the adjusting rod 204 protruding from the surface can be controlled to apply force and pull. When the adjusting rod 204 is pulled by force, it will drive the adjusting rod 204 to rise and fall to a certain extent. When the adjusting rod 204 rises, the limiting blocks 2042 connected in the grooves on both sides will be moved out of the through holes of the screening net 202, and then the limiting blocks 2042 will be deflected by the hinge shaft connected by the torsion spring, so that the adjusting rod 204 cannot be pressed against the through hole through the limiting blocks 2042, so as to control the rotation of the adjusting rod 204.
[0027] When the adjusting rod 204 rotates, the toothed ring 2041 will mesh with the rack of the displacement groove 2031, so that the adjusting rod 204 will drive the overlapping net 203 to a certain displacement when rotating. Because the overlapping net 203 overlaps with the holes on the screening net 202, the overlapping net 203 will be staggered with the holes on the screening net 202 when displaced, thereby adjusting the aperture of the hole to a certain extent, so as to adapt to filtering feed of different specifications.
[0028] Since the width of the tooth ring 2041 is wider than the rack in the displacement groove 2031, the adjusting rod 204 will mesh with the rack even if it rises to a certain height. At the same time, after the adjustment is completed, the adjusting rod 204 is pressed to re-engage it so that the limiting blocks 2042 near the top sides are re-again pressed against the inner walls of the through hole. The adjusting rod 204 is limited to a certain extent by the abutment of the anti-slip grooves on the side walls, so that its rotation will not be affected by the sliding of debris.
[0029] The following is a specific implementation process of the utility model. First, the feed that needs to be pretreated is poured into the screening box 2, and then slides along the screening net 202 in the screening box 2. During the sliding process, the feed will fall through the holes of the screening net 202 and be discharged and collected through the discharge port 201, while some larger impurities will slide directly to the other end through the screening net 202 and be discharged, thereby pre-treating and screening the feed. At the same time, when the feed is pre-treated and screened through the screening net 202, the adjusting rod 204 protruding from the surface can be controlled to apply force and pull. When the adjusting rod 204 is pulled by force, it will drive the adjusting rod 204 to rise and fall to a certain extent. When the adjusting rod 204 rises, the limiting rods connected in the grooves on both sides will be The fixed stop block 2042 moves out of the through hole of the screening net 202, and then the limiting stop block 2042 will be deflected by the hinge shaft connected by the torsion spring, so that the adjusting rod 204 cannot abut against the through hole through the limiting stop block 2042, so as to control the rotation of the adjusting rod 204, and when the adjusting rod 204 rotates, the tooth ring 2041 will engage with the rack of the displacement groove 2031, so that the adjusting rod 204 will drive the overlapping net 203 to a certain displacement when rotating. Because the overlapping net 203 overlaps with the holes on the screening net 202, the overlapping net 203 will be staggered with the holes on the screening net 202 when displaced, thereby adjusting the aperture of the holes to a certain extent, so as to adapt to the filtering of feed of different specifications.
[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
