A livestock feed production screening device

Abstract

This utility model discloses a screening device for livestock feed production, belonging to the field of feed production technology. It includes a support frame with a spring at the top and a connecting block at the top of the spring. A screening component is located on one side of the connecting block. This utility model uses a heating plate to heat the feed on the vibrating plate, preventing the moist feed from clumping together. The connecting plate and spring pads allow the vibrating plate to vibrate under the drive of the vibrating box, while the spring pads generate additional vibration to disperse dry, clump-like feed, facilitating subsequent screening and preventing large pieces of feed from falling onto the vibrating screen and causing damage. By simultaneously placing spring pads on both sides of the first and second vibrating screens, the elasticity of the spring pads allows the screen to vibrate at different frequencies and amplitudes during vibration, promptly shaking off feed particles adhering to the screen and preventing screen blockage.

[0002] In the current booming development of the livestock breeding industry, the quality of feed plays a key role in the healthy growth of livestock and poultry and the improvement of breeding efficiency. As an important link in the feed production process, feed screening aims to separate materials of different particle sizes, remove impurities, ensure the uniformity of feed particle size, and thus improve feed quality.

[0003] In existing screening devices, fibers and high-moisture particles in the feed tend to adhere to the screen mesh during the screening process, causing screen blockage and reducing screening efficiency and effectiveness. Therefore, a screening device for livestock feed production is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for livestock feed production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a screening device for livestock feed production, comprising a support frame, a spring on the top of the support frame, a connecting block on the top of the spring, and a screening component on one side of the connecting block;

[0006] The screening assembly includes a vibrating box, a motor on one side of the vibrating box, a connecting shaft at the output end of the motor, eccentric hammers at both ends of the connecting shaft, a flow guide assembly, a first vibrating screen and a second vibrating screen arranged sequentially from top to bottom on the inner side of the vibrating box, a discharge plate at the top of both the first and second vibrating screens, a filter screen with a groove on one side of the vibrating box, and a blower on one side of the filter screen.

[0007] The flow guiding assembly includes a vibrating plate, a heating plate inside the vibrating plate, connecting plates on both sides of the vibrating plate, spring pads on the outer side of the connecting plates, and temperature sensors at the four corners of the vibrating plate.

[0008] In a preferred embodiment, the vibrating plate, the first vibrating screen, the second vibrating screen, and the discharge plate are all inclined. The screen diameter of the first vibrating screen is smaller than that of the second vibrating screen. One end of the first vibrating screen is located above one end of the second vibrating screen, and one end of the vibrating plate is located above one end of the first vibrating screen.

[0009] In a preferred embodiment, the filter screen is located between the vibrating plate and the first vibrating screen. One end of the first and second vibrating screens is provided with a waste outlet. One end of the vibrating plate is located above one of the waste outlets. One end of the two discharge plates is provided with a discharge outlet, and the discharge outlet is connected to the vibrating box through the vibrating box.

[0010] In a preferred embodiment, the connecting shaft is connected through the vibration box, and a support platform is provided at the bottom of the motor, through which the motor is connected to the support frame.

[0011] In a preferred embodiment, both sides of the first and second vibrating screens are provided with connecting plates and spring pads, and the number of connecting plates and spring pads is six.

[0012] In a preferred embodiment, there are four springs and four connecting blocks, the vibration box is located between the four connecting blocks, and limit rings are provided on both sides of the vibration box, with the two eccentric hammers located inside the limit rings.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention controls the rotation of a motor to make an eccentric hammer rotate under the action of a connecting shaft, which in turn drives the vibrating box to vibrate under the action of springs. This allows the feed to be screened through a first vibrating screen and a second vibrating screen. A heating plate can heat the feed on the vibrating plate to prevent the moist feed from clumping together. By setting up a connecting plate and spring pads, the vibrating plate can vibrate under the action of the vibrating box, and the additional vibration generated by the spring pads can break up dry clumps of feed, thus facilitating subsequent screening and preventing large pieces of feed from falling onto the vibrating screen and causing damage. By setting spring pads on both sides of the first and second vibrating screens, the elasticity of the spring pads can cause the screen to vibrate at different frequencies and amplitudes during the vibration process, which can promptly shake off feed particles attached to the screen and prevent the vibrating screen from clogging.

[0015] This invention, by setting the vibrating plate, first vibrating screen, second vibrating screen, and discharge plate in an inclined manner, allows for better flow of feed within the vibrating screen, thus facilitating feed screening. The discharge plate allows for timely discharge and collection of screened feed. The first and second vibrating screens enable graded screening of feed, improving screening accuracy and efficiency. A blower positioned between the vibrating plate and the first vibrating screen blows the dried feed onto the first vibrating screen for screening. Impurities such as stones and metal in the feed are discharged from the waste outlet under gravity. A filter screen prevents feed or impurities from entering the blower and affecting its operation.

[0026] The flow guiding assembly 405 includes a vibrating plate 4051, a heating plate 4052 inside the vibrating plate 4051, connecting plates 4053 on both sides of the vibrating plate 4051, a spring pad 4054 on the outside of the connecting plate 4053, and temperature sensors 4055 at the four corners of the vibrating plate 4051.

[0027] By controlling the rotation of the motor 402, the eccentric hammer 404 can rotate under the action of the connecting shaft 403, which in turn drives the vibrating box 401 to vibrate under the action of the spring 2. Thus, the feed is screened through the first vibrating screen 406 and the second vibrating screen 407. The heating plate 4052 can heat the feed on the vibrating plate 4051. By setting the connecting plate 4053 and the spring pad 4054, the vibrating plate 4051 can vibrate under the action of the vibrating box 401, and the additional vibration generated by the spring pad 4054 can shake apart the dry clumps of feed. By setting the spring pad 4054 on both sides of the first vibrating screen 406 and the second vibrating screen 407, the elasticity of the spring pad 4054 can make the screen vibrate at different frequencies and amplitudes during the vibration process, which can shake off the feed particles attached to the screen in time and prevent the vibrating screen from clogging.

[0028] The vibrating plate 4051, the first vibrating screen 406, the second vibrating screen 407 and the discharge plate 408 are all inclined. The screen diameter of the first vibrating screen 406 is smaller than that of the second vibrating screen 407. One end of the first vibrating screen 406 is located above one end of the second vibrating screen 407, and one end of the vibrating plate 4051 is located above one end of the first vibrating screen 406.

[0029] The filter screen 409 is located between the vibrating plate 4051 and the first vibrating screen 406.

[0030] The connecting shaft 403 is connected through the vibration box 401. The bottom of the motor 402 is provided with a support platform 5, and the motor 402 is connected to the support frame 1 through the support platform 5.

[0031] Both sides of the first vibrating screen 406 and the second vibrating screen 407 are provided with connecting plates 4053 and spring pads 4054, and the number of connecting plates 4053 and spring pads 4054 is six.

[0032] There are four springs 2 and four connecting blocks 3. The vibrating box 401 is located between the four connecting blocks 3. Limiting rings 8 are provided on both sides of the vibrating box 401. The two eccentric hammers 404 are located inside the limiting rings 8. By setting the vibrating plate 4051, the first vibrating screen 406, the second vibrating screen 407 and the discharge plate 408 to be inclined, the feed can flow better inside the vibrating screen. The discharge plate 408 can discharge and collect the screened feed in time. The first vibrating screen 406 and the second vibrating screen 407 can be set to classify and screen the feed, which can improve the accuracy and efficiency of feed screening. The blower 410 set between the vibrating plate 4051 and the first vibrating screen 406 can blow the dried feed onto the first vibrating screen 406 for screening. Stones, metal and other impurities in the feed can be discharged from the waste port 7 under the action of gravity. The filter screen 409 can prevent feed or impurities from entering the blower 410 and affecting the use of the blower 410.

[0033] The working principle and usage process of this utility model are as follows: First, the feed is poured onto one end of the vibrating plate 4051. By controlling the rotation of the motor 402, the eccentric hammer 404 can rotate under the action of the connecting shaft 403, thereby driving the vibrating box 401 to vibrate under the action of the spring 2, causing the feed to flow to the first vibrating screen 406. Then, the feed on the vibrating plate 4051 can be heated by the heating plate 4052. By setting the connecting plate 4053 and the spring pad 4054, the vibrating plate 4051 can vibrate under the action of the vibrating box 401, and the additional vibration generated by the spring pad 4054 can... The dried, lumpy feed is shaken apart, and the blower 410 is started to blow the dried feed onto the first vibrating screen 406 for screening. Impurities such as stones and metals in the feed can be discharged from the waste port 7 under the action of gravity. Finally, the feed is screened through the first vibrating screen 406 and the second vibrating screen 407. By setting spring pads 4054 on both sides of the first vibrating screen 406 and the second vibrating screen 407, the elasticity of the spring pads 4054 can make the screen vibrate at different frequencies and amplitudes during the vibration process, which can shake off the feed particles attached to the screen in time and prevent the vibrating screen from clogging.
