Description

Technical Field

[0001] The utility model relates to the technical field of crushing and screening devices, in particular to a screening device for artificial domestication feed of seawater fish species which can be screened and crushed. Background Art

[0002] Crushing is to turn large particles into small particles. It is a process in feed processing. Cereals in compound feed (such as corn, sorghum, wheat, oats, etc.) almost all need to be crushed first and then mixed with other feed materials of a certain particle size. Crushing is one of the most important production links in a feed factory. After the feed raw materials are crushed, their surface area increases and they are easy to mix with enzymes in the intestines, which is beneficial to digestion and absorption of livestock and poultry, making subsequent work such as transportation, batching, mixing, and granulation more convenient.

[0003] After searching, for example, a utility model patent with Chinese patent number CN219503211U discloses a screening device for premixed feed, in which a screw feeder can transport raw materials, and the hot air in the mixing box can pre-dry the raw materials when discharged, and the first gear, the second gear and the two crushing rollers in the powder screening mechanism can crush the raw materials and improve the production effect of the feed. The matching arrangement of the extrusion plate, the screen and the spring can screen out suitable feed and improve the quality of the feed. However, the device only performs one screening during screening, and the screening effect is not good. Therefore, a screening device for artificial domestication feed of marine fish species that can be screened and crushed is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 In this embodiment, a screening device for artificial domestication feed of marine fish species that can be screened and crushed includes a crushing box 1. Two screening nets 4 are arranged inside the crushing box 1. A material shifting mechanism 5 is arranged on the screening net 4. The screening standards of the two screening nets 4 are different, thereby realizing graded screening. A box door is opened on the front side wall of the crushing box 1 to facilitate taking out the feed in the receiving frame 6.

[0024] A mounting frame 501 is fixedly installed on both sides of the crushing box 1, a material-discharging motor 502 is fixedly installed on the top of the mounting frame 501, a mounting opening 503 is opened on both sides of the left and right walls of the crushing box 1, a first rotating rod 504 is rotatably connected to the mounting frame 501, a second rotating rod 505 is rotatably connected in the mounting opening 503, a mounting shell 506 is fixedly installed on the inner walls of the left and right sides of the crushing box 1, a third rotating rod 507 is rotatably connected inside the mounting shell 506, a connecting rod 508 is slidably connected to the mounting shell 506, a material-discharging rod 509 is fixedly installed on one end of the connecting rod 508 away from the third rotating rod 507, a first gear 510 is fixedly installed on the outside of the first rotating rod 504, and a second rotating rod 505 is rotatably connected to the inside of the second rotating rod 505. A second gear 511 is fixedly installed on the outside, and a third gear 512 is fixedly installed on the outside of the third rotating rod 507. By setting up the material-moving mechanism 5, when the feed is screened through two screening nets 4, it can be screened twice, and the screening effect is better. By setting up the material-moving mechanism 5, when the feed falls on the screening net 4, by controlling the material-moving motor 502, the material-moving motor 502 drives the first rotating rod 504 and the first gear 510 to rotate, thereby driving the second gear 511 and the third gear 512 to rotate, so as to drive the material-moving rod 509 to swing on the screening net 4, realize the movement of the feed, and prevent the accumulation of feed from affecting the screening effect. The material-moving motor 502 rotates back and forth when rotating, so that the material-moving rod 509 swings back and forth.

[0025] A mounting groove is provided on the side of the material-push rod 509 away from the connecting rod 508, and a spring 7 is fixedly installed inside the mounting groove. A telescopic rod 8 is fixedly installed on the end of the spring 7 away from the material-push rod 509. By arranging the spring 7 and the telescopic rod 8, the total length of the material-push rod 509 can be extended or shortened when swinging to adapt to the size of the crushing box 1.

[0026] The device is not only convenient for grading and screening feeds, but also can prevent feed accumulation during screening, and can be widely promoted in applicable fields, such as artificial domestication of marine fish species, chicken feed processing, etc.

[0027] When implementing, follow these steps:

[0028] 1) First, feed is put into the crushing box 1 through the feed hopper on the top of the crushing box 1, and then the motor 2 is turned on to drive the crushing roller 3 to rotate and crush the feed. The crushed feed is screened by two screening nets 4, and the feed that meets the standards falls into the receiving frame 6 for collection;

[0029] 2) Then, when the feed falls on the screening net 4, the feed-moving motor 502 is controlled to drive the first rotating rod 504 and the first gear 510 to rotate, thereby driving the second gear 511 and the third gear 512 to rotate, so as to drive the feed-moving rod 509 to swing on the screening net 4, thereby moving the feed;

[0030] 3) Finally, the feed intercepted by the screening net 4 slides out from the discharge port due to gravity or the movement of the material-moving rod 509 so as to be collected and crushed again.

[0031] In summary, the screening device for artificially domesticated feed of marine fish species that can be screened and crushed, by setting the material-shifting mechanism 5, can perform two screenings when the feed is screened through two screening nets 4, and the screening effect is better. By setting the material-shifting mechanism 5, when the feed falls on the screening net 4, by controlling the material-shifting motor 502, the material-shifting motor 502 drives the first rotating rod 504 and the first gear 510 to rotate, thereby driving the second gear 511 and the third gear 512 to rotate, so as to drive the material-shifting rod 509 to swing on the screening net 4, realize the shifting of the feed, and prevent the accumulation of feed from affecting the screening effect; by setting the spring 7 and the telescopic rod 8, the total length of the material-shifting rod 509 can be extended or shortened when swinging, adapting to the size of the crushing box 1, and solving the problem of poor screening effect of the comparative device.
