Description

Automatic screening device and preparation equipment of pellet feed that poultry was fed Technical Field The invention relates to the technical field related to animal feed preparation, in particular to an automatic screening device and preparation equipment for granulated feed for livestock feeding. Background At present, a screen mesh mode is mainly adopted for screening stone grains in feed. However, the company finds that the screening method has a plurality of defects in the long-term practical application process. Because the aperture of the filter screen is fixed, when the filtering operation is carried out for a long time, some fine particles and impurities in the feed can be gradually accumulated on the surface of the filter screen, so that the filter screen is blocked. Once the filter screen is blocked, the actual filtering efficiency of the filter screen is seriously affected, so that the feed screening work cannot be smoothly carried out, and the production time and the cost are increased. Moreover, the condition of the filtered matters after being screened by the filter screen is complex, the filtered matters not only contain stone grains, but also are mixed with agglomerated feed, the feed is wasted due to direct dumping, the equipment and process cost can be increased due to additional treatment, the preparation efficiency is reduced, and adverse effects are brought to the production and operation of enterprises. For this reason, chinese patent publication No. CN120460270B discloses a livestock feed preparation device, which drives a screen drum to rotate through a driving shaft, and utilizes a relative movement relationship between a driving wheel and the inside of a housing in the process of rotating the screen drum. When the driving wheel rotates along with the screen cylinder and generates relative displacement with the inside of the shell, the driving wheel rotates and transmits and distributes power by utilizing the transmission gear set, so that the driving screen roller and the driven screen roller realize synchronous and opposite movement. After the feed enters the screen cylinder, the feed conforming to the distance between the driving screen roller and the driven screen roller can smoothly pass through the gap under the rotation action of the driving screen roller and the driven screen roller, so that the feed is screened out. The larger stone particles or agglomerated particles will be retained inside the screen cylinder because they cannot pass through the gap. At the same time, the driving and driven screen rollers continue to rotate, and this continuous movement generates a force that causes the filter material (i.e., those large particulate material that is not screened out) that is jammed therebetween to be driven by the driving and driven screen rollers, creating a tendency to move away from the filtering site. The trend effectively avoids the accumulation of the filter materials at the filtering part, prevents the occurrence of blocking, and finally realizes the good effect that the filtering part is not easy to block. The effect not only ensures the continuity and stability of the screening process, but also greatly improves the screening efficiency and reduces the time and labor cost for stopping and cleaning due to blockage. However, the above-mentioned comparison document still does not thoroughly solve the technical problem that the traditional screening device influences the separation of the feed because of the blocking of the feed in the working process, firstly, the anti-blocking design is not enough, the accumulation of the filtering objects at the gap between the driving screen roller and the driven screen roller can be avoided, the special anti-blocking structure is not designed for the screen holes of the screen cylinder, fine particles in the feed are easy to adhere to the inner wall of the screen holes, the blocking of the screen holes is caused after long-term operation, the effective separation of the feed from stone particles is hindered, secondly, the device lacks the capability of clearing the blocking in real time, is not provided with an auxiliary blocking clearing mechanism, once the blocking of the screen holes occurs, the problem of incapability of synchronous decomposition is solved, and further, the screening process is interrupted, the continuity and the efficiency of the separation of the feed are influenced, and the problem of the separation of the feed caused by the blocking of the screen holes cannot be fundamentally broken. Disclosure of Invention To above-mentioned problem, provide an automatic screening plant of pellet feed and preparation equipment that poultry was fed, solved traditional screening plant and influenced the technical problem of fodder separation because of fodder jam sieve mesh in the course of the work through frame, screening section of thick bamboo, drive arrangement and knocking device. The invention provides an automa
