Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a high-efficiency feed pellet mill for feed production. Background Technology

[0002] Feed pellet mills are core equipment in large-scale feed production. They extrude and cut mixed feed ingredients into pellets that are easy to store, transport, and consume by animals, directly affecting feed production efficiency and product quality.

[0003] The existing application publication number CN217490761U discloses a pelleting assembly for sow feed production, including a pelleting device. A support plate is installed on one side of the front end of the pelleting device, and a first rotating rod is rotatably arranged inside the pelleting device. An extrusion roller is provided on the outer wall of the first rotating rod, and a first transmission gear is installed at one end of the first rotating rod extending to the outer wall of the pelleting device. This pelleting assembly for sow feed production can realize the extrusion of feed and the subsequent cutting operation by controlling the motor and cooperating with the gears and other components, effectively improving resource utilization.

[0004] However, the cutting mechanism of this equipment is poorly designed. With its reciprocating cutting structure, the material at the discharge port is blocked by the blade holder during the return phase after cutting. This causes the material to be extruded later to get stuck in the gap of the discharge port, resulting in a blockage. This not only reduces the granulation efficiency but also requires frequent shutdowns for cleaning, affecting the continuity of production.

[0005] Therefore, those skilled in the art urgently need to develop a high-efficiency feed pellet mill for feed production. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency feed pellet mill for feed production.

The output end of the push plate cylinder 4 extends into the material cylinder 1 and is connected to the push plate 8. A sealing sleeve is provided on the left side wall of the material cylinder 1 at the through-hole of the piston rod of the push plate cylinder 4.

[0020] A cutting assembly 6 is provided on the right side of the discharge plate 9. The cutting assembly 6 includes a cutting blade 61 with an arc-shaped structure. Two supports 7 are placed side by side on the right side of the discharge plate 9. A rotating shaft 63 is provided between the two supports 7. There are two cutting blades 61, which are symmetrically distributed on both sides of the rotating shaft 63. The blade of the cutting blade 61 is made of tungsten steel. The contact gap between the blade and the discharge plate 9 is no more than 0.1mm. The handle of the cutting blade 61 is welded and fixed to the rotating shaft 63 through a connecting rod 62.

[0021] A drive motor 64 is fixedly mounted on the bracket 7 on one side via a motor mount. The output end of the drive motor 64 is fixedly connected to one end of the rotating shaft 63 via a coupling to drive the cutting blade 61 to make a circular motion. When the cutting blade 61 moves to contact the discharge plate 9, it remains in close contact.

[0022] Furthermore, the control valve 3 includes a valve body housing 32, which is fixedly embedded in the top feed inlet of the material cylinder 1. A discharge channel with vertical connection is opened in the middle of the valve body housing 32. The upper and lower ends of the discharge channel are respectively sealed and connected to the feed hopper 2 and the material cylinder 1. A horizontal insert plate 31 is inserted inside the valve body housing 32. The insert plate 31 and the valve body housing 32 are slidably and sealed together using a clearance fit + sealing ring sealing connection method. One end of the insert plate 31 extends to the outside of the valve body housing 32 and is fixedly connected to the piston rod of the control cylinder 33 through a coupling. The inner wall of the valve body housing 32 is provided with a guide groove adapted to the wear-resistant slider. The control cylinder 33 is fixed to the top outer wall of the material cylinder 1 by a support, and the extension and retraction direction of its piston rod is consistent with the sliding direction of the insert plate 31.

[0023] Furthermore, an inspection port is provided on the side of the material cylinder 1, and an inspection door 5 is provided at the inspection port. The inspection door 5 is rotatably connected to the material cylinder 1 via a hinge. A sealing strip is provided around the inner side of the inspection door 5, and a locking bolt is provided on the outer side of the inspection door 5.

[0024] Furthermore, the bottom of the discharge plate 9 is provided with a guide plate, which is placed at an angle, and a collection trough can be provided at the bottom of the guide plate.

[0025] Working principle of this utility model: 1. Feed raw materials to be pelleted (after crushing and pre-mixing) are added to the feed hopper 2. The control cylinder 33 is activated, driving the slide plate 31 to slide along the guide groove of the valve body shell 32, opening the discharge channel. The raw materials fall evenly into the feed cylinder 1 under gravity. The feed flow rate can be adjusted by controlling the opening stroke of the slide plate 31. After the raw materials have finished falling, the control cylinder 33 drives the slide plate 31 to reset and close the discharge channel to prevent the raw materials from overflowing during pelleting. Then, the push plate cylinder 4 is activated, and its piston rod pushes the push plate 8 to slide at a constant speed towards the discharge plate 9. The push plate 8 is tightly attached to the inner wall of the feed cylinder 1 through the elastic sealing gasket, squeezing the raw materials towards the discharge plate 9. Under pressure, the raw materials are squeezed out from the discharge port of the discharge plate 9, forming a continuous columnar material.

[0026] 2. While the push plate 8 is pressing the material, the drive motor 64 is started. The drive motor 64 drives the rotating shaft 63 to rotate at a set speed. The rotating shaft 63 drives two symmetrically arranged cutting blades 61 to make circular motion through the connecting rod 62. The columnar material squeezed out from the discharge port is cut in real time to form granular feed with uniform specifications. By adjusting the speed of the drive motor 64, the cutting frequency can be changed, thereby obtaining granules of different lengths. The cut granular feed falls onto the inclined guide plate under the action of gravity and slides along the guide plate into the collection trough to complete the collection.

[0027] The above description is only a preferred 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 technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
