Description

Technical Field

[0001] The utility model relates to the technical field of broken feed screening, in particular to a highly efficient broken feed grading and screening device. Background Art

[0002] Feed refers to the general term for food for all animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed processing refers to the production and processing of feed suitable for farms and farmers raising livestock and poultry, including the production of pet food. The production process of feed factories generally requires crushing and screening.

[0003] For example, a crushing and screening device for feed production with publication number CN217774261U includes a device body, which is convenient for cleaning to prevent filter holes from being blocked and affecting its use. When it is installed later, it is placed on a mounting block, so that it can be easily installed;

[0004] However, when the crushing and screening device for feed production is used, since there is no structure for recovering the feed on the filter screen, the feed that does not reach the standard size cannot be crushed for the second time, thereby reducing the use effect of the device. At the same time, the above-mentioned middle filter screen is inclined, so there is no cleaning structure on the filter screen. When some larger feed blocks the mesh of the filter screen, smaller feed will also be discharged from the first discharge port together with the larger feed, thereby reducing the screening effect of the feed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a crushing and screening device for feed production, which solves the problem that the existing feed crushing and screening device for feed production has no structure for recovering the feed on the filter net, so that the feed that does not reach the standard size cannot be crushed for the second time, and no cleaning structure is provided on the filter net. When some larger feed blocks the mesh of the filter net, the smaller feed will also be discharged from the first discharge port together with the larger feed.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: an efficient crushed feed grading and screening device, including a base plate and a first box body, the first box body is fixedly connected to the upper left side of the base plate, a plurality of grading screens are fixedly connected to the interior of the first box body, and a cleaning door connected to the first box body is provided at the upper rear end of the grading screen, a second box body is installed on the upper right side of the base plate, and a crushing mechanism is installed inside the second box body, the upper left side and the middle of the second box body are connected to the interior of the first box body through a first connecting channel and a pair of second connecting channels respectively, a screening mechanism is installed inside the first box body, and a third box body is fixedly connected to the left side of the first box body.

[0013] Beneficial Effects

[0014] The utility model provides an efficient crushed feed grading and screening device, which has the following beneficial effects:

[0015] The feed to be crushed can be poured into the first box through the feed hopper, and the second motor is started, so that the second motor cooperates with the gear to drive the two crushing rollers to move towards each other to crush the feed. At the same time, the crushed feed will be graded through the grading screen, and the feed that meets the crushing standard will be intercepted by the lowest grading screen, and the smaller dust materials will fall into the fourth box for storage, and the feed that does not meet the standard size will be intercepted by the upper and middle grading screens. After that, the push plate pushes the feed on the upper and middle grading screens into the second box through the second connecting channel, and then the first motor is started, so that the first motor cooperates with the conveying auger to transport the feed, so that the feed is discharged into the middle above the two crushing rollers through the first connecting channel, and then the push plate is reset, and the second motor is started. The second motor cooperates with the gear to drive the two crushing rollers to move towards each other, and the feed is crushed twice by the crushing roller, which not only avoids the congestion of materials on the screen surfaces of the first grading screen and the second grading screen, but also improves the use effect of this device;

[0016] When it is necessary to clean the feed on the upper and middle grading screens, the crushing roller can be stopped and the third motor can be started so that the third motor cooperates with the pulley and belt to drive the screw to rotate. The screw cooperates with the cross bar to drive the push plate to move to the right, and the push plate pushes the feed on the upper and middle grading screens into the second box through the second connecting channel. In this way, the blocked feed on the upper and middle grading screens can be cleaned, thereby ensuring the subsequent feed screening effect. At the same time, the cleaning door at the bottom is always open, and the feed that meets the crushing standard can be cleaned. BRIEF DESCRIPTION OF THE DRAWINGS
