Description

Technical Field

[0001] This utility model relates to the field of feed grading technology, specifically to a feed grading sieve. Background Technology

[0002] Feed is the food that humans give to animals. It is very important for the growth and development of animals and directly affects their growth, health and final quality. Choosing the right feed is crucial for improving breeding efficiency and economic benefits. When producing feed, because feed particles vary in size, it is necessary to classify and grade the feed according to the particle size to ensure that the particle size of each batch of feed is uniform and to ensure the consistency of feed product quality, so as to improve the animals' eating efficiency, growth efficiency and health level.

[0003] When using a grading screen to grade feed, the concentrated entry of feed into the screen can lead to excessive feed intake and accumulation, which can cause blockages in the grading process, reducing grading efficiency and preventing quantitative and rapid grading of feed. Therefore, we have proposed a feed grading screen to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a feed grading screen to solve the problem mentioned in the background art that in the current market, due to the concentrated entry of feed into the grading screen, too much feed enters, and the accumulated feed easily causes blockage in the grading process, reducing the efficiency of grading and making it impossible to quantify and quickly grade the feed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feed grading sieve, comprising an outer shell, a motor installed inside the outer shell, a rotating shaft connected to the output end of the motor, a connecting frame installed at the lower end of the rotating shaft, a grading box connected to the end of the connecting frame, and a baffle connected to the side of the grading box;

[0006] The grading box has a feed inlet on the upper side, a lower discharge outlet on the side, an upper discharge outlet on the side away from the lower discharge outlet, and a discharge outlet on the lower side. The grading box is equipped with a first filter plate and a second filter plate.

[0007] A discharge pipe is installed in the middle of the lower end of the outer shell, and a third discharge port is opened on the left side of the discharge pipe;

[0008] The outer casing has a first discharge port on its left side, a second discharge port on its right side, and a feeding port on its top.

[0009] A scraper is installed below the grading box.

[0010] Preferably, the upper end of the outer shell is inclined, and the upper end of the outer shell is inclined toward the feeding port.

[0011] Preferably, the bottom surface inside the outer casing is inclined, and the bottom surface inside the outer casing is parallel to the scraper.

[0012] Preferably, the first filter plate is located above the second filter plate, and the mesh size of the first filter plate is larger than that of the second filter plate.

[0013] Preferably, the lower end of the discharge pipe penetrates the outer casing, and the lower end of the discharge pipe is open.

[0014] Preferably, the grading boxes are distributed at equal angles with respect to the longitudinal centerline of the outer shell, and the grading boxes are connected by a connecting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This feed grading screen can drive the grading box to rotate by controlling the connecting frame and adjusting the position of the grading box. The position of the feed inlet and the position of the feed outlet intermittently coincide, so that the feed can be quantitatively put into the grading box for grading and screening. The grading boxes distributed at equal angles can continuously and quickly screen the feed, avoiding the accumulation and blockage of the feed.

[0017] (2) When the feed grading screen controls the rotation of the grading box to perform quantitative and rapid grading of feed, the outer shell and the discharge pipe block the feed, which increases the time the feed stays in the grading box, so that the feed can be fully graded and the feed can be discharged before grading is completed, thereby improving the grading and sieving accuracy of the feed.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution: a feed grading sieve, including an outer shell 1, a motor 2 installed inside the outer shell 1, a rotating shaft 3 connected to the output end of the motor 2, a connecting frame 4 installed at the lower end of the rotating shaft 3, a grading box 5 connected to the end of the connecting frame 4, and a baffle 6 connected to the side of the grading box 5.

[0027] Furthermore, the grading boxes 5 are distributed at equal angles with respect to the longitudinal centerline of the outer shell 1, and the grading boxes 5 are connected by the connecting frame 4, so that the feed can be graded and screened continuously and quantitatively using the grading boxes 5.

[0028] The grading box 5 has an inlet 7 on the upper side, a lower distribution port 10 on the side, an upper distribution port 18 on the side away from the lower distribution port 10, and a discharge port 11 on the lower side. The grading box 5 is equipped with a first filter plate 8 and a second filter plate 9 inside.

[0029] Furthermore, the first filter plate 8 is located above the second filter plate 9, and the mesh size of the first filter plate 8 is larger than that of the second filter plate 9, which can classify and screen the feed.

[0030] A discharge pipe 13 is installed in the middle of the lower end of the outer casing 1, and a third discharge port 14 is opened on the left side of the discharge pipe 13;

[0031] Furthermore, the lower end of the discharge pipe 13 penetrates the outer shell 1, and the lower end of the discharge pipe 13 is open, allowing medium-sized feed to be discharged from the discharge pipe 13.

[0032] The outer casing 1 has a first discharge port 12 on its left side, a second discharge port 15 on its right side, and a feeding port 17 on its top.

[0033] Furthermore, the upper end of the outer shell 1 is inclined, and the upper end of the outer shell 1 is inclined towards the feeding port 17, so that the feed can be concentrated in the feeding port 17 and easily enter the grading box 5.

[0034] A scraper 16 is installed below the grading box 5;

[0035] Furthermore, the bottom surface inside the outer shell 1 is inclined, and the bottom surface inside the outer shell 1 is parallel to the scraper 16, which can smoothly concentrate the smallest feed separated by grading to the second discharge port 15 for discharge.

[0036] Specifically, the feed is concentrated at the top of the outer shell 1 and then along the inclined surface of the top to the feeding port 17. The motor 2 is powered on, and the rotating shaft 3 connected to the output end is rotated clockwise, thereby controlling the connecting frame 4 installed at the end of the rotating shaft 3 to rotate, which in turn controls the grading box 5 to rotate clockwise. When the position of the feed inlet 7 on the upper side of the grading box 5 coincides with the position of the feeding port 17, the feed can enter the grading box 5 and be graded and screened inside the grading box 5. When the position of the feed inlet 7 is misaligned with the position of the feeding port 17, the baffle 6 is used to block the feeding port 17, stopping the feed from entering and realizing the quantitative feeding and screening of the feed.

[0037] The feed entering the grading box 5 is first filtered through the first filter plate 8. Larger particles remain on the first filter plate 8, smaller particles fall onto the second filter plate 9, and the smallest particles fall from the second filter plate 9 to the bottom of the grading box 5. Finally, the feed is discharged into the outer shell 1 through the discharge port 11. As the grading box 5 rotates, when the position of the upper distribution port 18 coincides with the position of the third discharge port 14, the feed on the first filter plate 8 enters the discharge pipe 13 and is discharged. When the positions of the lower distribution port 10 and the first discharge port 12 coincide, the feed on the second filter plate 9 is discharged from the lower distribution port 10 and the first discharge port 12. The smallest particles of feed entering the outer shell 1 are concentrated at the second discharge port 15 by the scraper 16 and discharged, thus achieving feed grading and screening. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
