Description

Technical Field

[0001] This utility model belongs to the field of feed pelleting technology, specifically referring to a pelleting device for cattle and sheep feed production. Background Technology

[0002] The pelleting production of cattle and sheep feed involves crushing, extruding, and supporting mixed feed ingredients into granular feed using specific equipment. This process increases the surface area of ​​the feed, significantly improving its utilization efficiency. Furthermore, the uniform particle size makes it easier for livestock to digest and absorb, thus maximizing its nutritional value.

[0003] Existing pelleting equipment, when using high-speed rotating blades to cut feed, mostly uses a filter screen to intercept and filter the crushed feed to ensure uniform particle size. However, the crushed feed particles are of different sizes, which can easily clog the filter screen during filtration, thus preventing smooth feeding and affecting pelleting efficiency.

[0004] Furthermore, since cattle and sheep require different feed pellet sizes at different growth stages, existing pelleting devices often depend on their own weight and feed viscosity during extrusion molding, making it impossible to guarantee uniform pellet size and flexibly change pellet length, resulting in poor practicality. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a pelleting device for cattle and sheep feed production, which effectively solves the problem that the existing pelleting device is prone to blockage and poor feeding when screening the crushed feed, and also solves the problem that the feed length cannot be guaranteed to be uniform.

[0006] The technical solution adopted by this utility model is as follows: This utility model proposes a pelleting device for cattle and sheep feed production, including a receiving tray. A ring die, a conveying pipe, and a feeding hopper are sequentially fixed to the middle of the upper end of the receiving tray by bolts. A screen is fixed to the bottom of the feeding hopper and is located inside the conveying pipe. A guide rod perpendicular to the bottom of the screen is fixed to the middle. A top rod is sleeved on the lower end of the guide rod. The top rod has an H-shaped cross-section, and a return spring is provided between the upper ends of the guide rod and the top rod. It also includes a cutting ring sleeved on the outside of the ring die. Support plates are fixed on the receiving trays on both sides of the ring die. A cutting drive assembly is provided on the support plate and is connected to the cutting ring.

[0007] As an improvement to this solution, a pressure roller group is rotatably connected to the receiving plate inside the ring mold, and a rotating shaft is fixed in the middle of the upper end of the pressure roller group. Sliding shafts are vertically fixed on both sides of the top end of the rotating shaft. Two sets of spiral slide rails are symmetrically distributed on the inner wall of the bottom end of the push rod, and the spiral slide rails and the sliding shafts can slide relative to each other.

[0008] As an improvement to this solution, the cutting drive assembly includes a servo motor fixed to the upper end of the support plate. One end of the output shaft of the servo motor is fixed with a connecting rod, and the other end of the connecting rod is rotatably connected to a push rod. Meanwhile, the other end of the push rod is rotatably connected to the side wall of the cutting ring.

[0009] As an improvement to this solution, a granulation drive assembly connected to a rotating shaft is provided on the side wall of the conveying pipe. The granulation drive assembly includes a protective cover fixed to the side wall of the conveying pipe and the protective cover is disposed through the conveying pipe. The rotating shaft is disposed through the protective cover. Both ends of the bottom of the protective cover are rotatably connected to synchronous pulleys. One set of synchronous pulleys is fixed on the rotating shaft, and the two sets of synchronous pulleys are connected by a synchronous belt. A pressing motor is fixed at the upper end of the protective cover outside the conveying pipe. The output shaft of the pressing motor is disposed through the protective cover and connected to the synchronous pulleys.

[0010] As an improvement to this solution, a turntable is rotatably connected to the upper end of the receiving tray, and a crushing motor is fixed to the inner wall of the upper end of the feeding hopper by a round rod. A round shaft is fixedly connected to the output end of the crushing motor, and a crushing blade is fixed to the lower end of the round shaft, with the crushing blade positioned above the screen.

[0011] As an improvement to this solution, a baffle plate is fixed at the upper end of the pressure roller assembly, and a spiral slide rail is set through the baffle plate. The baffle plate allows the screened feed to be smoothly introduced between the pressure roller assembly and the ring die.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] 1. By setting a top rod at the bottom of the filter screen and using the spiral slide rail on its inner wall, it can be raised and lowered by the slide rail on the upper side wall of the rotating shaft while the rotating shaft drives the pressure roller to rotate. This allows the top to periodically impact the screen, causing it to vibrate and preventing the feed particles from clogging after crushing, ensuring smooth feeding and improving pelleting efficiency.

[0014] 2. By using the ring cutter set on the outer wall of the ring die, the feed pellets after being extruded by the pressure roller can be cut off, which improves the uniformity of the size of the formed pellets and helps to improve the quality of the feed. Furthermore, by setting servo motors on both sides, the cutting length can be controlled by changing the rotation speed, making it simple to operate and convenient to use.

The top rod 7 has an H-shaped cross-section, and a return spring 8 is provided between the upper ends of the guide rod 6 and the top rod 7. The device also includes a cutting ring 9 sleeved on the outside of the ring die 2. Support plates 10 are fixed on the receiving trays 1 on both sides of the ring die 2. A cutting drive assembly 11 is provided on the support plate 10 and is connected to the cutting ring 9.

[0023] like Figure 2 and Figure 4As shown, a pressure roller group 12 is rotatably connected to the receiving plate 1 inside the ring mold 2, and a rotating shaft 13 is fixed in the middle of the upper end of the pressure roller group 12. Sliding shafts 15 are vertically fixed on both sides of the top end of the rotating shaft 13. Two sets of spiral slide rails 14 are symmetrically distributed on the inner wall of the bottom end of the push rod 7, and the spiral slide rails 14 and the sliding shafts 15 can slide relative to each other.

[0024] like Figure 3 As shown, the cutting drive assembly 11 includes a servo motor 16 fixed to the upper end of the support plate 10. One end of the output shaft of the servo motor 16 is fixed with a connecting rod 17, and the other end of the connecting rod 17 is rotatably connected to a push rod 18. Meanwhile, the other end of the push rod 18 is rotatably connected to the side wall of the cutting ring 9.

[0025] To drive the rotating shaft 13, a granulation drive assembly 19 connected to the rotating shaft 13 is provided on the side wall of the conveying pipe 3. The granulation drive assembly 19 includes a protective cover 20 fixed on the side wall of the conveying pipe 3 and the protective cover 20 is set through the conveying pipe 3. The rotating shaft 13 is set through the protective cover 20. Both ends of the bottom of the protective cover 20 are rotatably connected to synchronous wheels 21. One set of synchronous wheels 21 is fixed on the rotating shaft 13, and the two sets of synchronous wheels 21 are connected by a synchronous belt 22. A pressing motor 23 is fixed at the upper end of the protective cover 20 outside the conveying pipe 3. The output shaft of the pressing motor 23 passes through the protective cover 20 and is connected to the synchronous wheels 21.

[0026] like Figure 1 As shown, a turntable 24 is rotatably connected to the upper end of the receiving tray 1, and a crushing motor 25 is fixed to the inner wall of the upper end of the feeding hopper 4 by a round rod.

Then, when the spiral slide rail 14 separates from the slide shaft 15, it is reset by the return spring 8. This process is repeated to keep the screen 5 unobstructed. While the rotating shaft 13 rotates, it drives the bottom pressure roller group 12 to rotate, extruding the screened material through the through holes on the surface of the ring die 2 to complete the pelleting. Then, the servo motor 16 is turned on to drive the connecting rod 17 to rotate, so that the connecting rod 17 pushes the push rod 18 to drive the cutting ring 9 to move up and down along the outer surface of the ring die 2. In this process, the extruded feed pellets are cut. The cut feed pellets fall onto the external turntable 24.
