Description

Technical Field

[0001] The present invention relates to the field of poultry breeding feed processing, and in particular to a poultry breeding feed crushing and screening integrated machine and a control method thereof. Background Art

[0002] Poultry farming is an important agricultural industry, which includes many types of poultry, so many types of breeding feed are needed. For example, corn, wheat, rice, etc. are rich in carbohydrates and are the main source feed used in poultry farming.

[0003] Before use, feed needs to be crushed. During this process, a feed crusher is needed. The crusher can break larger feed ingredients such as corn and grains into appropriate particle sizes, making them easier for poultry to chew and swallow. This improves the poultry's acceptance of the feed and increases their feed intake. For example, for chickens, the crushed feed particles are of moderate size, and they will not be difficult to swallow due to large particles that affect their eating.

[0004] However, the existing poultry feed crusher can only perform a single crushing process on the feed during use, and cannot perform multi-stage crushing processing on the feed according to the type of poultry being raised. Therefore, it cannot meet the crushing processing of different poultry feeds, and thus cannot meet people's use needs.

[0047] A control method for a poultry feed crushing and screening integrated machine, comprising:

[0048] Step 1: First, connect the bottom end of the conveying hose 42 to the grain, and control the crushing component 1 to rotate and operate, so that the internal pressure of the crushing chamber 48 is negative, and the grain is sucked into the crushing chamber 48 for crushing. The crushed grain will be filtered by the filter ring 41 and discharged downward;

[0049] Step 2: If the grain does not need to be crushed again, it can be discharged through the first vertical guide pipe 45. If further crushing is required, the grain can be controlled to be discharged through the second oblique guide pipe 49 into the interior of the multi-stage crushing component 2 for crushing;

[0050] Step 3: Also see if further crushing is needed. If crushing is continued, the secondary crushed grain can be discharged into the third-stage crushing bucket 29 for further crushing.

[0051] Step 4: Finally, the vibrating component 3 controls the screening component 5 to vibrate and screen the falling grain.

[0052] The working principle of the present invention is as follows: first, the bottom end of the conveying hose 42 is connected to the grain, and then the drive motor 16 is controlled to rotate. At the same time, the second transmission chain 15 drives the transmission shaft 11 to rotate synchronously. The transmission shaft 11 drives the crushing disk 14 at one end to rotate at high speed in the crushing chamber 48, causing negative pressure inside the crushing chamber 48, sucking the grain into the crushing chamber 48. When the grain contacts the high-speed rotating crushing disk 14, it is impacted and crushed. The crushed grain is filtered by the filter ring 41 and discharged downward into the first vertical feed guide pipe 45.

[0053] If it is not necessary to crush the grain again, it can be discharged directly downward through the first vertical guide pipe 45. If it is necessary to crush the grain further, the plunger cylinder 37 can be controlled to extend and run, thereby driving the limit frame 36 to move. At the same time, the limit frame 36 will synchronize the movement of the second transmission rack 35, so that the second transmission rack 35 drives the first gear plate 25 engaged with the upper portion to rotate. At the same time, the first gear plate 25 will drive the deflector 23 to deflect through the connecting rope 43 and the rotating shaft 22, so that the deflector 23 blocks the inside of the first vertical guide pipe 45, so that the crushed grain is discharged into the inside of the secondary crushing bucket 21 through the second oblique guide pipe 49, wherein the transmission shaft 11 will pass through the first transmission chain 12 while rotating. The second transmission sprocket 211 is driven to rotate, and the second transmission sprocket 211 drives the two groups of crushing rollers 26 inside the secondary crushing bucket 21 synchronously. Since the ends of the two groups of crushing rollers 26 are meshed and connected to each other through the transmission gear 27, the two groups of crushing rollers 26 will rotate synchronously in opposite directions, thereby performing secondary crushing processing on the falling feed. The size of the second transmission sprocket 211 is twice the size of the first transmission sprocket 13. Therefore, when the transmission shaft 11 drives the second transmission sprocket 211 to rotate through the first transmission chain 12, the rotation speed of the second transmission sprocket 211 is half of that of the transmission shaft 11. Therefore, the rotation speed of the second transmission sprocket 211 is slower than the rotation speed of the transmission shaft 11, thereby ensuring that the crushing rollers 26 can crush the feed normally.

[0054] Then, it is also determined whether the feed needs to be further crushed. If the feed needs to be further crushed, the secondary crushed grain can be discharged into the third-stage crushing bucket 29. At the same time, it is necessary to control the plunger cylinder 37 to continue to extend and operate, and continue to drive the vibration shaft 33 to slide horizontally through the limit frame 36, so that the first transmission rack 34 drives the first gear plate 25 engaged with the upper portion to deflect. At the same time, the first gear plate 25 will drive the guide plate 23 to deflect through the rotating shaft 22, thereby blocking the second vertical guide pipe 24, so that the feed passes through the first oblique conduit 2 10 enters the interior of the three-stage crushing bucket 29, wherein the second transmission sprocket 211 rotates, and drives the transmission rod 28 to rotate synchronously through the fourth transmission chain 212, so that the transmission rod 28 drives the two sets of crushing rollers 26 inside the three-stage crushing bucket 29 to rotate synchronously in the opposite direction, thereby crushing the feed entering the three-stage crushing bucket 29 again. Finally, the feed crushed by the crushing rollers 26 will be discharged downward to the upper surface of the screening component 5. When the transmission rod 28 rotates, it will drive the vibration shaft 33 to rotate synchronously through the third transmission chain 31, and the vibration shaft 33 will drive the two ends The vibration block 32 on the outer surface rotates synchronously, so that the vibration block 32 frequently supports the bottom of the screening component 5, so that the screening component 5 vibrates and deflects up and down with the limiting shaft sleeve 46 as the center, thereby accelerating the screening component 5 to screen the feed on the upper surface. The plunger cylinder 37 drives the vibration shaft 33 to slide horizontally through the limiting frame 36, and at the same time adjusts the vibration position of the vibration block 32 on the bottom of the screening component 5. Therefore, when the vibration block 32 approaches the limiting shaft sleeve 46, the vibration efficiency of the screening component 5 will be improved. In addition, the third transmission chain 31 is slidably overlapped on the outer surface of the tensioning wheel 412. The surface, so when the vibration shaft 33 slides, it will pull the third transmission chain 31 to move, and the tensioning wheel 412 can keep the third transmission chain 31 in a tensioned state under the tension of the tensioning spring 410, thereby ensuring the normal transmission function of the third transmission chain 31. Therefore, through the coordinated operation of the crushing component 1, the multi-stage crushing component 2, the vibration component 3, the protective support component 4 and the screening component 5, the poultry breeding feed can be multi-stage crushed and processed, and the crushed feed can be subjected to multi-stage vibration synchronous screening, so as to obtain breeding feed of different particle sizes to meet people's usage needs.

[0055] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
