Technical Field
[0001] The utility model belongs to the technical field of livestock feed screening devices, and particularly relates to a livestock feed screening device. Background Art
[0002] In animal husbandry, the quality and utilization rate of feed are directly related to the growth rate, health status and quality of the final product of the animals. During the production, storage and transportation of feed, impurities, lumps or particles of different sizes are often mixed in, which will affect the uniformity and palatability of the feed, and thus affect the digestion and absorption efficiency and production performance of the animals.
[0003] Traditional feed screening methods mostly use fixed screens or vibrating screens. Although these methods can achieve feed screening to a certain extent, they have many shortcomings. For example, fixed screens have low screening efficiency, are prone to clogging, require frequent cleaning, and are difficult to disassemble for later maintenance. Although vibrating screens have high screening efficiency, they have complex structures, high energy consumption, and inconvenient adjustment of screening accuracy. Traditional screening equipment can often only achieve single-size screening and cannot meet the diverse feed particle size requirements of different types of animals and different growth stages.

[0006] The beneficial effects of the utility model are:
[0007] Through the reciprocating impact of the oscillating component and the coordinated action of the telescopic rod, the collecting bucket produces a strong oscillation effect, thereby accelerating the screening speed of the feed and improving the screening efficiency. At the same time, the design of the semicircular screening plate enables the feed to be fully dispersed during the screening process, reducing blockage and further improving the screening efficiency.
[0008] By adjusting the rotation of the semicircular baffle in the adjustment component, the screening method and screening particle size can be flexibly adjusted. Users can choose a variety of screening methods such as coarse screening, fine screening, or fine screening followed by coarse screening according to actual needs to meet the special needs of different types of animals and different growth stages for feed.
[0009] The cleaning brush set on the semicircular baffle can clean the screen plate during the rotation process, effectively removing impurities and residues generated during the screening process, maintaining the cleanliness of the screen plate, and reducing the occurrence of blockage. At the same time, the overall structure of the equipment is reasonably designed, easy to disassemble and clean, and reduces maintenance costs.
[0010] The device is driven by an electric motor, has low energy consumption, and has a compact structure and occupies a small area.
[0011] In order to fix the position of the barrel cover and the limiting sleeve:
[0012] As a further improvement of the above technical solution: four groups of screws are fixed at equal intervals on the top of the screening barrel, and the screws pass through the top of the limiting sleeve and are slidably connected to it. A leakage port is opened at the center of the bottom end of the screening barrel, and the top of the screw passes through the barrel cover and is slidably connected to it, and a threaded nut is installed on the outer side of the screw.
[0013] The beneficial effect of this improvement is: when using this device, the user can place the limit sleeve in the screening barrel.

A motor is fixed on the outside of the outer shell, and the sub-rotating shaft of the motor is connected to the other end of the worm gear. A rotating groove is opened at the center of the bottom end of the rotating rod, and the rotating groove is engaged with a movably connected positioning rod. The positioning rod is fixed at the top center of the limit rod, and the lower side of the rotating rod is connected to the center of one side of the semicircular baffle. The size of the semicircular baffle is the same as that of the semicircular screening plate one and the semicircular screening plate two, and the bottom end of the semicircular baffle fits above the rotating semicircular screening plate one and the semicircular screening plate two.
[0016] The beneficial effect of this improvement is that when the barrel cover is limited and installed on the limit sleeve, the positioning rod is in a state of being embedded in the rotating groove. The user can adjust the position of the semicircular baffle according to the size of the feed to be screened, and start the motor through the controller to drive the worm to rotate. At this time, the rotating worm causes the worm gear meshing with it to drive the rotating rod to rotate. At this time, the semicircular baffle connected to the rotating rod will rotate with the rotating rod as the axis, so that it rotates to the top of the unused screening plate to block it, so that the unblocked screening plate can start to screen the feed.
[0017] To screen the feed:

[0019] The beneficial effects of this improvement are: this device can be used in three ways: coarse screening, fine screening, and coarse screening again after fine screening of feed. According to user needs, if fine screening of feed is required, the semicircular baffle can be rotated to block the semicircular screening plate one, and at this time the semicircular screening plate two can be used to finely screen the feed. Similarly, coarse screening means rotating the semicircular baffle to block the semicircular screening plate two to coarse screen the feed, and coarse screening again after fine screening, that is, first rotate the semicircular baffle to block the semicircular screening plate one, and after the semicircular screening plate two has finished screening the feed that meets the size, rotate the semicircular baffle to block the semicircular screening plate two through the adjustment component to start coarse screening again.

One side of the bottom end of storage chamber one and storage chamber two respectively passes through the outside of the collecting barrel and is fixed with discharge pipe one and discharge pipe two, and the baffle is provided below the limit rod.
[0025] The beneficial effect of this improvement is that the provided storage chamber 1 and storage chamber 2 can store the coarsely screened and finely screened feed, and the screened feed can be discharged through the discharge pipe 1 and discharge pipe 2.
[0026] In order to speed up the screening efficiency of the semicircular screening plate 1 and the semicircular screening plate 2 for feed:
