Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4, a livestock and poultry concentrated feed drying equipment with a screening structure, including a drying tank body 1, a circulating conveying component 3 for circulating concentrated feed is provided inside the drying tank body 1, the surface of the circulating conveying component 3 is provided with a screen plate 7, and an extrusion plate 6 is provided above the screen plate 7 in parallel, a vibration component 5 is provided on one side of the extrusion plate 6 and the screen plate 7, a second guide slider 10 is fixedly connected to both sides of the screen plate 7, and a lifting spring 9 is provided above the second guide slider 10, one end of the lifting spring 9 is fixed to the second guide slider 10, and the other end is fixed in the guide chute provided at the connection with the drying tank body 1;

A cam 504 is provided on one side of the transmission gear 503. The cam 504 is located below one set of second guide sliders 10. A guide groove is provided at the connection between the second guide sliders 10 and the drying tank body 1.

[0029] The vibration assembly 5 also includes a transmission gear rod 505 installed on one side of the transmission gear 503, and the transmission gear rod 505 is meshed with the transmission gear 503. The top of the transmission gear rod 505 is fixedly connected to a lifting rod 506, and the top of the lifting rod 506 is fixedly connected to a support rod 507. The end of the support rod 507 is fixed on the extrusion plate 6, and the extrusion plate 6 is slidably installed inside the drying tank body 1. A first guide slider 8 is provided on both sides of the extrusion plate 6, and a guide groove is also provided at the connection between the first guide slider 8 and the drying tank body 1. The support rod 507 and the second guide slider 10 are offset from each other, which does not affect the mutual extrusion of the extrusion plate 6 and the screen plate 7.

[0030] By adopting the above technical solution, the feed dropped between the extrusion plate 6 and the screen plate 7 can be screened by the screen plate 7 and then dropped into the interior of the drying tank 1, and then enter the interior of the drying tank 1 for drying. The bottom of the drying tank 1 is a conical structure, so that it can re-enter between the extrusion plate 6 and the screen plate 7 through the circulating conveying component 3. When the screen plate 7 screens the feed, the servo motor 501 can be started at the same time. The servo motor 501 drives the transmission shaft 502 to rotate, and the transmission shaft 502 drives the transmission gear 503 and the cam 504 to rotate synchronously. As the cam 504 rotates, the screen plate can be pushed. 7 is lifted and lowered in the drying tank body 1, and the screen plate 7 is lifted and lowered in the drying tank body 1 through the second guide slider 10, and at the same time, the lifting spring 9 is squeezed, and the lifting spring 9 is stretched and rebounded, thereby driving the screen plate 7 to vibrate, thereby shaking off the feed stuffed in the sieve holes of the screen plate 7. At the same time, the transmission gear 503 drives the transmission gear rod 505 to move downward, and the extrusion plate 6 can push the feed downward under the action of the first guide slider 8 to further avoid feed blockage. At the same time, the servo motor 501 can choose a reciprocating motor, and the reciprocating motor rotates forward and reverse within a certain period of time, thereby adjusting the height of the extrusion plate 6.

[0031] Specifically, such as Figure 2 As shown, the circulating conveying component 3 includes a feeding pipe 302, a feeding screw 303 is installed inside the feeding pipe 302, and the top of the feeding screw 303 is fixedly connected to the power output end of the feeding motor 301; a feed port is provided on the lower surface of the feeding pipe 302, and a discharge port is provided on the upper surface of the feeding pipe 302, and the discharge port is located between the extrusion plate 6 and the screen plate 7, a feed bin 2 is installed on the surface of the drying tank body 1, and the feed bin 2 is connected to the drying tank body 1, the feed bin 2 is located between the extrusion plate 6 and the screen plate 7, and a heating pipe 4 is also installed on the inner wall of the drying tank body 1.

[0032] By adopting the above technical solution, the feed enters the feed pipe 302 through the feed port at the bottom of the feed pipe 302. After driving the feed motor 301, the feed motor 301 drives the feed screw 303 to rotate. The feed screw 303 transports the feed upward and is discharged from the discharge port into between the extrusion plate 6 and the screen plate 7. The extrusion plate 6 and the screen plate 7 are vibrated by the vibration component 5 on the vibration component 5. The heating tube 4 uses a spiral heating wire to heat the inside of the drying tank 1, thereby drying the feed. The feed motor 301 works in an intermittent mode. When the extrusion plate 6 and the screen plate 7 move away from each other, the feed re-enters the top of the screen plate 7 through the discharge port.

[0033] Working principle: the feed enters the interior of the drying tank body 1 through the feed bin 2 and is screened by the screen plate 7. During the screening process, the servo motor 501 is started synchronously. At this time, the servo motor 501 drives the transmission shaft 502 to rotate, and the transmission shaft 502 drives the transmission gear 503 and the cam 504 to rotate synchronously. As the cam 504 rotates, the screen plate 7 can be pushed up and down in the drying tank body 1. The screen plate 7 is lifted and lowered in the drying tank body 1 through the second guide slider 10, and the lifting spring 9 is squeezed at the same time. The lifting spring 9 stretches and rebounds, thereby driving the screen plate 7 to vibrate, thereby shaking off the feed stuffed in the sieve holes of the screen plate 7. At the same time, the transmission gear 503 drives the transmission The gear rod 505 moves downward, and the extrusion plate 6 can push the feed downward under the action of the first guide slider 8, further avoiding feed blockage. At the same time, the servo motor 501 can choose a reciprocating motor, and the reciprocating motor rotates forward and reverse within a certain period of time to adjust the height of the extrusion plate 6. The heating tube 4 heats the interior of the drying tank 1 to dry the feed inside, and the internal feed enters the feed pipe 302 through the feed port at the bottom of the feed pipe 302. After driving the feed motor 301, the feed motor 301 drives the feed screw 303 to rotate, and the feed screw 303 transports the feed upward and discharges it back into the space between the extrusion plate 6 and the screen plate 7 through the discharge port until the feed is completely dry.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
