[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] refer to Figure 1-4 , shows a feed pelletizer with particle screening function for feed production, including a pelletizing unit 1 and a screening unit 2, the pelletizing unit 1 includes a body 11, the body 11 is provided with a pelletizing chamber 12 and a material receiving chamber 13 located above the pelletizing chamber 12, a vertically arranged rotating shaft 14 is provided in the pelletizing chamber 12, a rotating disk 15 is connected to the rotating shaft 14, the rotating disk 15 is arranged between the pelletizing chamber 12 and the material receiving chamber 13, a plurality of through holes 151 are provided on the rotating disk 15, the rotating shaft 14 is transmission-connected to a driving motor 18 The receiving chamber 13 is provided with a feeding port 131 at the upper part, and a plurality of pressure rollers 16 are provided in the receiving chamber 13; a discharge port 121 is provided at one side of the granulating chamber 12, and a scraper 17 located below the turntable 15 is provided in the granulating chamber 12; the screening unit 2 includes a vibration frame 21 arranged at one side of the discharge port 121, an oscillation motor 23 and an inclined screen 22 are provided on the vibration frame 21, a mounting plate 24 is provided below the vibration frame 21, and a plurality of buffer members are provided between the vibration frame 21 and the mounting plate 24.

[0032] Specifically, when in use, the crushed feed material can be poured into the receiving chamber 13 from the feeding port 131, and the driving motor 18 drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the rotating disk 15 to rotate, and the rotating disk 15 drives the crushed feed material above it to rotate. During the rotation of the crushed feed material, the crushed feed material enters the gap between the pressing roller 16 and the rotating disk 15, and is crushed by the pressing roller 16 and pressed into the perforation 151 on the rotating disk 15. The crushed feed material is discharged from the pressing roller 16. The perforations 151 extend downward to the granulation chamber 12. During the rotation of the turntable 15, the scraper 17 scrapes the feed raw material crushed material extending downward from the turntable 15 to form particles. Then, the particles are discharged from the discharge port 121 and fall onto the screen 22 on the vibration frame 21. The vibration energy is generated by the operation of the vibration motor 23, so that the vibration frame 21 vibrates and drives the screen 22 to vibrate. When the particles slide down along the screen 22, they will be screened by the screen 22, so that particles with too small particle size are screened out.

[0033] In this way, the screening unit 2 is used to screen the particles produced by the granulation unit 1, so that the particles with too small particle size are separated, the difference in particle size of the same batch of feed is reduced, and the stability of feed production is improved; at the same time, the screening unit 2 uses the oscillation motor 23 to vibrate the vibration frame 21, thereby improving the screening efficiency of the screen 22 for particles and reducing the leakage rate. The vibration frame 21 and the mounting plate 24 are isolated by the buffer component, which can reduce the loss of vibration energy on the vibration frame 21 and avoid the vibration frame 21 from generating too much noise.

[0034] The inclination angle of the screen 22 may be 10-30°.

[0035] In some embodiments, in order to improve the rolling effect of the pressing roller 16 on the crushed feed raw materials, Figure 3 The pressing roller 16 is rotatably arranged around a horizontal axis in the receiving chamber 13, and a plurality of slots are provided on the outer wall of the pressing roller 16, and a tooth portion is formed between two adjacent slots. In this way, the tooth portion has a claw-crushing action on the feed raw material crushed material, which can improve the crushing degree of the feed raw material crushed material and improve the mixing effect of the feed raw material crushed material.

[0036] In some embodiments, reference Figure 1 and Figure 2 The discharge port 121 is provided with an inclined guide plate 19, through which the particles in the granulation chamber 12 can stably fall onto the screen 22 to prevent the particles from scattering on the ground.

[0037] In some embodiments, reference Figure 4The vibration frame 21 includes a support plate 211, one side of the support plate 211 is provided with two inclined side support rods 212, and the screen 22 is arranged between the two side support rods 212; the bottom of the support plate 211 is connected to a vertical support rod 213, one side of the vertical support rod 213 is provided with a horizontal support rod 214, and the buffer member is arranged between the horizontal support rod 214 and the mounting plate 24; the oscillation motor 23 is arranged on the support plate 211.

[0038] In this embodiment, a C-shaped support structure is formed between the side support rods 212, the support plate 211, the vertical support rods 213 and the transverse support rods 214. The screen 22 is arranged on the side support rods 212, so that one end of the screen 22 is suspended in the air. When the oscillation motor 23 on the support plate 211 generates a vibration force, the vibration amplitude of the suspended end of the screen 22 will be greater than the end of the screen 22 close to the support plate 211, so that the particles on the screen 22 are thrown up, which can avoid the particles from being mixed together and the small particles cannot be screened out, and can improve the screening effect.

[0039] In some embodiments, the buffer member is a spring or a rubber block. In this embodiment, a spring is used as the buffer member.

[0040] In some embodiments, in order to prevent the side support rod 212 from bending due to excessive particles, refer to Figure 4 The vibration frame 21 further includes a reinforcing rod 215, one end of which is connected to the middle of the vertical support rod 213, and the other end is connected to the bottom of the side support rod 212. In this way, the structural strength of the side support rod 212 is improved by the reinforcing rod 215, so that more particles can be screened on the screen 22.

[0041] In some embodiments, reference Figure 1 A first aggregate box 3 is provided below the screen 22, and a second aggregate box 4 is provided at the lower end of the screen 22. In this embodiment, the first aggregate box 3 is used to collect the particles with small particle size that are screened out, and the second aggregate box 4 is used to collect the particles with qualified particle size, so that the particles with large and small particle sizes can be collected separately, which is convenient for subsequent packaging and other processing.

[0042] In some embodiments, reference Figure 4 The mounting plate 24 is provided with a fixing hole 241, and an expansion bolt is arranged in the fixing hole 241 to fix the mounting plate 24 on the ground. In this way, by making the mounting plate 24 stably fixed on the ground, the stability of the vibration frame 21 during vibration is improved.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
