[0017] In order to make the patent purpose, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0018] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.
[0019] For the sake of convenience of description, only parts related to the embodiments of the present utility model are shown.
[0020] Combined with Figures 1-4As shown in the figure, the pig feed granulator includes a machine platform 1, on which a screw conveyor 2, a mixing bin 3, and a granulating mechanism are successively arranged from top to bottom. The granulating mechanism includes a cylinder 4 and a ring die 5 installed on the machine platform 1. The cylinder 4 is fixedly installed, and the ring die 5 is rotatably installed. The ring die 5 is located inside the cylinder 4. The discharge port of the screw conveyor 2 is communicated with the feed inlet of the mixing bin 3. A feeding bin 6 is provided at the discharge port of the mixing bin 3, and the bottom of the feeding bin 6 points to the inside of the ring die 5. The ring die 5 is provided with a circle of die holes 7. A connecting arm 8 is arranged on the shaft rod of the ring die 5. A pair of pressing rollers 9 are rotatably arranged on the connecting arm 8. The outer ends of the shaft rods of the two pressing rollers 9 are jointly rotatably provided with a connecting plate 10. A stirring frame 11 is arranged on the connecting plate 10. A scraper 12 is arranged on the cylinder 4 and faces the ring die 5. A driving mechanism for driving the rotation of the ring die 5 is also arranged on the machine platform 1.
[0021] Pig feed usually consists of protein feed, energy feed, roughage, green feed, silage, mineral feed, and feed additives for feeding domestic pigs. During the production process of feed, multiple stages of processing are required, and some feeds need to be granulated. The breeding industry uses pellet feed to feed livestock, and the feed granulator is an essential processing machine.
[0022] When using this feed granulator to process feed, first, various feed raw materials are poured into the screw conveyor in a certain proportion. The feed raw materials are transported to the mixing bin through the screw conveyor. The feed raw materials are stirred in the mixing bin and then transported to the granulating mechanism for granulation. Since the screw conveyor is a prior art, it will not be described in detail here.
[0023] In this structure, as Figure 5 , a stirring shaft 13 is rotatably arranged in the mixing bin 3. A spiral stirring paddle 14 is arranged on the stirring shaft 13. A stirring motor 15 for driving the rotation of the spiral stirring paddle 14 is arranged on the machine platform 1.
[0024] During the feed transportation process, the feed raw materials pass through the screw conveyor and the mixing bin successively. The screw conveyor can play a role in transportation on the one hand, and at the same time, it can also break up the agglomerated feed, thereby improving the granulation quality. When the feed raw materials are transported into the mixing bin, the spiral stirring paddle rotates under the drive of the stirring motor. Various feed raw materials can be mixed more evenly under the stirring of the spiral stirring paddle, so that the processed feed particles are more nutritionally balanced. At the same time, during the stirring process, the spiral stirring paddle continuously transports the feed raw materials to the granulating mechanism through the feeding bin for granulation, which can make the granulation effect better.
[0025] In this device, as Figure 1 、 Figure 3The ring die 5 is provided with a receiving hopper 16 , the receiving hopper 16 extends out of the feeding port of the barrel 4 , and the stirring frame 11 is arranged toward the receiving hopper 16 .
[0026] In the actual structure, a pellet outlet is provided at the bottom of the barrel, and a pellet outlet interval is formed between the barrel and the ring die. The bottom of the lower feed bin extends into the receiving hopper. The feed raw materials fall from the lower feed bin into the receiving hopper and fall into the ring die. At the same time, the driving mechanism drives the ring die to rotate, and the connecting arm rotates with the ring die. The two pressure rollers also rotate along the inner wall of the ring die. The pressure rollers continuously crush the feed raw materials in the ring die during the rotation process. The feed raw materials enter the die hole, and the feed raw materials passing through the die hole form strip-shaped feed. After the strip-shaped feed is squeezed out of the die hole, since the ring die is in a rotating state during the granulation process, the strip-shaped feed is cut into particles by the scraper after being squeezed out of the die hole. The particles fall into the discharge interval and are discharged from the pellet outlet.
[0027] During granulation, the feed raw materials pass through the lower bin and the receiving hopper and finally fall into the ring die. At the same time, the stirring frame rotates in the receiving hopper driven by the ring die. The stirring frame stirs the feed in the receiving hopper into the ring die, which can avoid the feed raw materials from accumulating in the receiving hopper.
[0028] The barrel 4 is provided with a sleeve 17, a connecting rod 18 is screwed into the sleeve 17, and a scraper 12 is provided at the bottom of the connecting rod 18, and the scraper is in contact with the outer wall of the ring die. During the granulation process, the feed raw materials are squeezed into the die hole to form a strip feed, and after the strip feed is squeezed out, the die holes are cut one by one by the scraper to become granules. In this structure, the scraper is mainly installed on the barrel using the connecting rod.
[0029] Further as a priority structure, such as Figure 1 , Figure 4 The driving mechanism includes a chassis 20 installed on the machine platform 1, the barrel 4 and the ring die 5 are respectively installed on the chassis 20, a driving shaft 21 is rotatably provided in the chassis 20, a rotating gear 22 is respectively provided on the shaft rod of the ring die 5 and the driving shaft 21, the rotating gear 22 is meshedly installed, and a driving motor 23 for driving the driving shaft 21 to rotate is provided on the machine platform 1.
[0030] During granulation, when the driving mechanism is used to drive the ring die to rotate, first the driving motor drives the driving shaft to rotate, and then the ring die rotates under the linkage of the rotating gear.
[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the present utility model.
