Description

Technical Field

[0002] The raw materials of feed are generally corn, soybean, wheat bran, rice bran, broken rice, and sorghum. When preparing pellet feed, various raw materials are usually poured into a granulator, and the granulator crushes and directly presses various raw materials into pellet feed;

[0003] In the process of pressing feed by the existing pellet feed granulator, generally, three synchronously rotating toothed rollers are used to press the raw materials into a backing plate arranged below the toothed rollers. The raw materials pressed into the backing plate pass through the holes arranged in the backing plate and flow out from the lower end of the backing plate, and then a cutting knife is used to cut the feed flowing out of the backing plate to form pellet feed;

[0004] However, in the existing feed pelletizing method during the pressing process in the holes, since the upper and lower ends of the holes are connected, it is impossible to ensure that the feed is sufficiently compacted in the holes, resulting in the feed being relatively loose after flowing out of the holes, and the prepared feed is prone to powdering and cannot prepare complete pellet feed.

[0054] Please refer to Figure 1-8 , the present invention provides a technical solution:

[0055] A pellet feed production line includes a bracket 100 and a blanking cylinder 101 provided at the upper end of the bracket 100, and further includes:

[0056] A crushing unit 2 is provided at the feed inlet of the blanking cylinder 101 for crushing and stirring the raw materials put into the blanking cylinder 101.

[0070] Furthermore, as Figure 8 shown, the ejecting mechanism 125 includes:

[0071] A circular plate 1251 is slidably inserted inside the retreat groove 1212;

[0072] A pressing shaft 1252 is connected to the upper end of the circular plate 1251, and is used to cooperate with the toothed roller 113 to press down the circular plate 1251;

[0073] The upper end of the pressing shaft 1252 penetrates through the inside of the first backing plate 121 and extends above the first backing plate 121;

[0074] A receiving hole 1253 is provided inside the circular plate 1251, and is used to receive the guide cylinder 1213;

[0075] The ejection shaft 1254 is connected to the lower end of the circular plate 1251 and corresponds to the third discharge hole 1231 one by one, and is used to eject the raw materials transferred in the second discharge hole 1221 along the third discharge hole 1231;

[0076] The return spring 1255 is sleeved outside the ejection shaft 1254 and is located at the lower end of the circular plate 1251, and is used to reset the circular plate 1251 after being pressed down.

[0077] Among them, as Figure 7 shown, the outer side of the switching plate 122 is provided with propulsion teeth 1222 at equal angles;

[0078] The transmission mechanism 124 includes:

[0079] The intermittent wheel 1241 is provided with intermittent teeth 12411 on its side that match the propulsion teeth 1222, and is used to drive the propulsion teeth 1222 to rotate intermittently to complete the switching work of the switching plate 122;

[0080] The first transmission shaft 1242 is connected to the upper end of the intermittent wheel 1241 and is used to drive the intermittent wheel 1241 to rotate;

[0081] The second transmission shaft 1244 is connected to the upper end of the crushing unit 2, and the second transmission shaft 1244 is connected to the first transmission shaft 1242 through a belt 1243.

[0082] As an improvement, the crushing unit 2 includes:

[0083] The drive shaft 20 is arranged on the upper end of the compaction assembly 11;

[0084] The crushing teeth 21 are fixedly sleeved outside the drive shaft 20 and are used to crush the raw materials entering the blanking cylinder 101;

[0085] The baffle 23 is fixed inside the blanking cylinder 101 and is used to block the falling of the raw materials during the crushing process;

[0086] The paddle 22 is rotatably connected inside the blanking cylinder 101 and is located above the baffle 23, and a material discharge port 221 is provided at the corresponding position inside it and the baffle 23;

[0087] The adjusting rod 222 is connected to the outside of the paddle 22 and is used to adjust the position of the paddle 22.

[0088] Furthermore, the drive assembly 13 includes:

[0089] The drive motor 131 is installed on the upper end of the bracket 100;

[0090] The first helical gear 132 is connected to one side of the drive motor 131;

[0091] The second helical gear 133 is meshed with the first helical gear 132 , and an extension shaft 1331 is connected to the upper end thereof for driving the compacting assembly 11 , the granulating assembly 12 and the crushing assembly to rotate synchronously;

[0092] A sleeve 1332 is sleeved on the outer side of the extension shaft 1331 .

[0093] It should be noted that the first pad 121 in the present invention is fixedly connected to the extension shaft 1331, the switching plate 122 is rotationally connected to the extension shaft 1331, and the third pad 123 is fixedly connected to the extension shaft 1331 to ensure that the switching plate 122 can rotate relative to the extension shaft 1331, and the first pad 121 and the third pad 123 rotate synchronously with the extension shaft 1331.

[0094] It should be noted that, in the specific implementation process of the present invention, initially, the discharge port 221 is closed by the paddle 22. Figure 1-2 , Figure 7 As shown, a variety of different raw materials are poured into the paddle 22 from the upper opening of the blanking barrel 101, and the raw materials fall onto the paddle 22 for accumulation. The driving motor 131 is started, and the driving motor 131 drives the second bevel gear 133 to rotate through the first bevel gear 132. The second bevel gear 133 drives the rotating shaft 111 to rotate through the extension shaft 1331. The rotating shaft 111 drives the crushing teeth 21 to rotate through the driving shaft 20, so that the various raw materials on the paddle 22 can be crushed by the crushing teeth 21 and stirred at the same time, ensuring that the various raw materials can be fully crushed before compaction, and can be stirred and mixed with each other while being crushed, so that the nutritional components of the multiple groups of raw materials can be evenly distributed when they are subsequently pressed into pellets.

[0095] After the raw materials are crushed and stirred, the adjusting rod 222 is rotated, and the adjusting rod 222 drives the paddle 22 to rotate, so that the discharge port 221 and the baffle 23 are staggered. At this time, the raw materials in powder form after being crushed and stirred enter the pressing unit 1 for pressing. After the raw materials on the paddle 22 completely fall into the pressing unit 1, the adjusting rod 222 is rotated in the opposite direction so that the baffle 23 blocks the discharge port 221 again, and then a variety of uncrushed raw materials are poured into the upper end opening of the blanking barrel 101 again, so that the crushing work and the pressing work are carried out simultaneously, and the working efficiency is high.

[0096] like Figure 4-8As shown in the figure, the lower end of the first discharge hole 1211 is initially connected to the second discharge hole 1221 in the switching plate 122. The raw materials broken in the pressing unit 1 first fall on the upper end of the first cushion plate 121. The rotating shaft 111 drives the mounting shaft 112 to rotate through the mounting sleeve 1111. The mounting shaft 112 drives the toothed roller 113 to rotate along the upper surface of the first cushion plate 121. The toothed roller 113 continuously presses the broken raw materials along the first discharge hole 1211 into the second discharge hole 1221. The lower end of the second discharge hole 1221 is blocked by the third cushion plate 123. The rotating shaft 111 also drives the first transmission shaft 1242 to rotate through the second transmission shaft 1244 under the action of the belt 1243. The first transmission shaft 1242 drives the switching plate 122 to rotate by one unit under the cooperation of the intermittent gear 1241 and the advancing tooth 1222, so that the second discharge hole 1221 in the original switching plate 122 is connected to the first discharge hole 1211 through the upper inlet, and the lower outlet is blocked by the third cushion plate 123 and is switched to the upper inlet blocked by the first cushion plate 121, and the lower outlet is connected to the third discharge hole 1231. At this time, the toothed roller 113 pushes the pressing shaft 1252 downward, and the pressing shaft 1252 pushes the ejecting shaft 1254 downward through the circular plate 1251, so that the compacted raw materials in the switching plate 122 are ejected by the ejecting shaft 1254 along the third discharge hole 1231. During this process, the raw materials in the first discharge hole 1211 are still continuously compacted by the toothed roller 113. After the pellet feed compacted in the second discharge hole 1221 is ejected, the toothed roller 113 disengages from the pressing shaft 1252, and the circular plate 1251 and the ejecting shaft 1254 are reset synchronously under the action of the return spring 1255. The switching plate 122 rotates by one unit again under the drive of the intermittent gear 1241, so that the first discharge hole 1211 is connected to the second discharge hole 1221 again, thus achieving the effect of ensuring that the raw materials are completely compacted and the prepared feed is not easily dispersed and pulverized;

[0097] The feed discharged along the third discharge hole 1231 slides along the sliding plate 102 into the loading frame 103 for collection.

[0098] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0099] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
