Abstract
Description
Technical Field
[0001] This utility model is a feed screening machine, belonging to the field of feed screening equipment. Background Technology
[0002] Feed is the general term for food for all animals raised by humans. In daily production activities, the particle size of feed has a significant impact on feed quality. Taking pig feed as an example, pigs have a relatively simple digestive system. When the particle size is large, the digestion and absorption of feed is slower, which affects the growth rate of pigs. Therefore, the particle size of pig feed with different raw material ratios needs to be matched with the digestive system of pigs.
[0003] When existing screening devices are used, a certain amount of oversized concentrate feed particles that do not meet the requirements are usually obtained. These oversized concentrate feed particles often need to be collected manually and then put back into the crushing device for secondary processing. This not only greatly increases the workload of workers, but also increases the screening process to a certain extent, thus affecting the efficiency of concentrate feed screening. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a feed screening machine.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0006] A feed screening machine includes a screening box, a cover plate fixedly connected to the upper surface of the screening box, a primary screening trough, a guide trough and a guide trough respectively opened in the screening box, a screening component is provided between the screening box and the primary screening trough and the primary screening trough and the guide trough, the screening box is slidably connected between two spring frame plates, the two spring frame plates are respectively fixedly connected to one end of two support legs, and the other end of the support legs is fixedly connected to the ground.
[0007] Furthermore, the screening component includes three spring pads that are fixedly connected to both sides of the screening box. One end of a spring is fixedly connected to the upper and lower surfaces of each spring pad, and the other end of the spring is fixedly connected to the inner wall of a spring receiving groove, which is formed on a spring frame plate.
[0008] Furthermore, the screening assembly also includes a primary screening plate fixedly connected inside the screening box, with a primary screening slot opened between the primary screening plate and the cover plate.
[0009] Furthermore, the screening assembly also includes a secondary screening plate fixedly connected inside the screening box, with a secondary screening slot opened between the secondary screening plate and the primary screening plate.
[0010] Furthermore, the screening assembly also includes a guide plate fixedly connected inside the screening box, with a guide groove formed between the guide plate and the secondary screening plate.
[0011] Furthermore, the screening assembly also includes guide plates that are fixedly connected to the screening box, the primary screening plate, the secondary screening plate, and the guide plate respectively.
[0012] Furthermore, the screening component also includes a guide plate, on which a primary feeding trough, a secondary feeding trough, and a tertiary feeding trough are respectively opened. The primary feeding trough, the secondary feeding trough, and the tertiary feeding trough are connected to the primary screening trough, the secondary screening trough, and the guide trough, respectively.
[0013] Furthermore, the primary screening plate has primary sieve holes, the secondary screening plate has secondary sieve holes, and a vibration motor is fixedly connected to the lower surface of the guide plate.
[0014] The beneficial effects of this utility model are:
[0015] By setting up the screening components, the vibration motor is started to drive the screening box and the spring pads on both sides to vibrate by squeezing the springs up and down. Then, the screening box simultaneously drives the primary screening plate, the secondary screening plate and the guide plate to vibrate. This completes the multiple screening of the feed. There is no need to manually collect the oversized concentrate particles and put them back into the crushing device for secondary processing, which saves time and effort. Attached Figure Description

[0021] 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.
[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a feed screening machine technical solution, including a screening box 1, a cover plate 6 fixedly connected to the upper surface of the screening box 1, a primary screening groove 8, a primary screening groove 15 and a guide groove 16 respectively opened in the screening box 1, a screening assembly is provided between the screening box 1 and the primary screening groove 8, the primary screening groove 15 and the guide groove 16, the screening box 1 is slidably connected between two spring frame plates 2, the two spring frame plates 2 are respectively fixedly connected to one end of two support legs 3, and the other end of the support legs 3 is fixedly connected to the ground.
[0023] See Figure 2 and Figure 3The screening assembly includes three spring pads 9 fixedly connected to both sides of the screening box 1. One end of a spring 10 is fixedly connected to the upper and lower surfaces of each spring pad 9, and the other end of the spring 10 is fixedly connected to the inner wall of a spring receiving groove 7, which is formed on a spring frame plate 2. The screening assembly also includes a primary screening plate 11 fixedly connected inside the screening box 1, with a primary screening groove 8 formed between the primary screening plate 11 and the cover plate 6. The screening assembly also includes a secondary screening plate 12 fixedly connected inside the screening box 1, with a secondary screening groove 15 formed between the secondary screening plate 12 and the primary screening plate 11. The screening assembly also includes a secondary screening plate 12 fixedly connected inside the screening box 1. The screening assembly includes a guide plate 13, with a guide groove 16 between the guide plate 13 and the secondary screening plate 12. The screening assembly also includes a guide plate 17, which is fixedly connected to the screening box 1, the primary screening plate 11, the secondary screening plate 12 and the guide plate 13 respectively. The guide plate 17 is provided with a primary feeding groove 18, a secondary feeding groove 19 and a tertiary feeding groove 20 respectively. The primary feeding groove 18, the secondary feeding groove 19 and the tertiary feeding groove 20 are respectively connected to the primary screening groove 8, the secondary screening groove 15 and the guide groove 16.

[0024] In use, the feed is poured onto the primary screening plate 11 through the feed trough 5. Then, the vibration motor 14 is started, which drives the screening box 1 and the spring pads 9 on both sides to vibrate by pressing the springs 10 up and down. At the same time, the screening box 1 drives the primary screening plate 11, the secondary screening plate 11 and the guide plate 13 to vibrate. The primary screening plate 11 then vibrates to screen the feed once. The screened feed falls through the primary screen holes onto the secondary screening plate 12, and the feed that does not fall falls through the primary screening trough 8 and the primary discharge trough 18 to the designated position. Then, the secondary screening plate 12 vibrates to screen the feed a second time. The screened feed falls through the secondary screen holes onto the guide plate 13, and the feed that does not fall falls through the secondary screening trough 15 and the secondary discharge trough 19 to the designated position. Then, the guide plate 13 guides the feed and then it falls through the guide trough 16 and the tertiary discharge trough 20 to the designated position. This completes the multiple screening of the feed. There is no need to manually collect the oversized feed particles and put them back into the crushing device for secondary processing, which saves time and labor.
