Detailed Implementation
[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0026] like Figures 1-6 As shown, the concentrated feed grading and grinding device provided in this embodiment includes a shell 1, a grinding mechanism disposed inside the shell 1, a driving mechanism disposed on the shell 1, and a screening mechanism. The grinding mechanism includes a crushing roller group 2 rotatably mounted on the inner wall of the shell 1. The crushing rollers inside the crushing roller group 2 cooperate with each other. A pulverizing blade group 3 is rotatably connected to the inner wall of the shell 1 and located below the crushing roller group 2. The concentrated feed is fed into the shell 1 and then crushed by the crushing roller group 2. The crushed concentrated feed is in granular form. Then the granular concentrated feed falls onto the pulverizing blade group 3, which pulverizes the granular concentrated feed and breaks it into powder. The powdered concentrated feed is screened by the screening mechanism to remove concentrated feed that does not meet the fineness requirements.
[0027] In this embodiment, as Figures 1-5 As shown, the screening mechanism includes mating grooves 5 and mounting frames 6 on two sides of the outer casing 1. A filter screen 7 is set in the middle of the mounting frame 6. A vibrator 11 is fixedly connected to the upper surface of the mounting frame 6, and a connecting rod 9 is fixedly connected to the lower surface of the mounting frame 6. A connecting sleeve 8 is slidably connected to one end of the connecting rod 9. The surface of the connecting sleeve 8 is fixedly connected to the outer casing 1. A spring 10 is set inside the connecting sleeve 8. When powdered concentrated feed falls onto the filter screen 7, the vibrator 11 vibrates, which in turn drives the mounting frame 6 to vibrate, causing the connecting rod 9 and the connecting sleeve 8 to slide. At the same time, the spring 10 is compressed to buffer and provide amplitude, thereby increasing the screening speed of the powdered concentrated feed. The mounting frame 6 is tilted to one side of the outer casing 1 to facilitate the movement of the powdered concentrated feed. Unqualified concentrated feed is discharged from the mating groove 5.
[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the drive mechanism includes a drive motor 12. The front of the housing 1 is fixedly connected to the drive motor 12. The output end of the drive motor 12 passes through the housing 1 and is connected to the crushing roller assembly 2. A gear assembly 13 and a pulley assembly 15 are provided on the back of the housing 1. The gear assembly 13 is connected to the crushing roller assembly 2, and the pulley assembly 15 is connected to the crushing blade assembly 3. A transmission pulley 14 is provided on the gear assembly 13. The gear assembly 13 is connected to the pulley assembly 15 through the cooperation of the transmission pulley 14 and the belt. A protective cover 16 is fixedly connected to the back of the housing 1. The pulley assembly 15 and gear assembly 13 are both located inside the protective cover 16. The protective cover 16 shields the transmission pulley 14, pulley assembly 15, and gear assembly 13, making it difficult for workers to touch them and improving the safety of the device. The drive motor 12 drives one of the crushing rollers in the crushing roller assembly 2 to rotate. The gear assembly 2 then drives the other crushing rollers in the crushing roller assembly 2 to rotate. At the same time, the gear assembly 13 drives the pulley assembly 15 to rotate through the transmission pulley 14 and the belt, thereby driving the crushing blade assembly 3 to rotate.
[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, a feed seat 4 is provided on the upper surface of the outer shell 1, and a guide plate 17 is fixedly connected to the inner wall of the outer shell 1 at the feed seat 4. A discharge port 18 is provided at the bottom of the outer shell 1, and a support leg 19 is fixedly connected to the lower surface of the outer shell 1. Concentrated feed is fed into the feed seat 4 and falls onto the guide plate 17 after passing through the feed seat 4. The guide plate 17 restricts the position of the concentrated feed, making it difficult for the concentrated feed to fall out of the gap between the crushing roller group 2 and the outer shell 1. The concentrated feed after screening is discharged from the discharge port 18.
[0030] In this embodiment, as Figures 1-6 As shown, the working principle of the concentrated feed grading and grinding device provided in this embodiment is as follows:
[0031] The drive motor 12 is started, driving one crushing roller in the crushing roller group 2 to rotate. The gear group 2 engages in transmission, thereby driving the other crushing rollers in the crushing roller group 2 to rotate. At the same time, the gear group 13 drives the pulley group 15 to rotate through the engagement of the transmission pulley 14 and the belt, thereby driving the crushing blade group 3 to rotate. The concentrated feed is fed in from the feed seat 4. The concentrated feed falls onto the guide plate 17 after passing through the feed seat 4. The guide plate 17 restricts the position of the concentrated feed, making it difficult for the concentrated feed to fall out of the gap between the crushing roller group 2 and the outer shell 1. The mounting frame 6 is tilted to one side of the outer shell 1 to facilitate the movement of the powdered concentrated feed. Unqualified concentrated feed is discharged from the feed seat 1. The concentrated feed is discharged from the trough 5. The crushing roller group 2 crushes the concentrated feed into granules. The granules fall onto the crushing blade group 3, which crushes the concentrated feed into powder. The powder falls onto the filter screen plate 7. The vibrator 11 vibrates, which in turn drives the mounting frame 6 to vibrate, causing the connecting rod 9 and the connecting sleeve 8 to slide. At the same time, the compression spring 10 provides buffering and amplitude, thereby increasing the screening speed of the powder concentrated feed. Unqualified concentrated feed is discharged from the mixing trough 5. The concentrated feed after screening is discharged from the discharge port 18.
[0032] When preparing granular concentrated feed, the belt on the drive pulley 14 is removed, so that the crushing blade assembly 3 does not work. The granular concentrated feed falls onto the filter screen plate 7, the concentrated feed powder is screened out, and the granular concentrated feed is discharged from the mixing tank 5.
[0033] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
