Description

Technical Field

[0001] The utility model relates to the technical field of feed equipment, in particular to a feed unloading device for a feed factory. Background Art

[0002] Feed is the food of animals raised in agriculture or animal husbandry. The development of animal husbandry now adopts mechanical methods, and so does the production of feed. Generally, the produced feed will be stored in the storage bin, and then it will be bagged or other unloading actions will be performed later. Although the existing unloading device is simple, it still has certain shortcomings in actual work:

[0003] First, when unloading the feed, the position and height of the unloading will vary. Therefore, when the height of the storage bin is fixed, the height of the unloading port is fixed, which may make unloading inconvenient or even cause leakage, which needs to be cleaned up later. Moreover, when unloading, the feed falls all at once after the unloading port is opened, which may cause excessive unloading or cause large dust due to unloading too quickly.

[0004] Secondly, in the process of unloading, since the unloading port is located at the bottom and is small, it is easy to cause blockage at the top of the unloading port under the action of pressure, which will affect the subsequent unloading efficiency and is not conducive to production. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a feed unloading device for a feed factory, which has the advantages of high applicability, stable material unloading and no clogging, and solves the problems raised by the background technology.

A telescopic shaft is movably sleeved at the bottom of the limiting sliding groove, and the telescopic shaft extends into the middle of the spiral blade. A cylindrical groove is formed in the middle of the spiral blade and extends to the bottom to form an abutting groove. The bottom of the telescopic shaft abuts against the abutting groove movably.

[0008] Furthermore, a limiting strip is fixedly connected to the top of the telescopic shaft. The bottom of the limiting sliding groove is cylindrical and the top is rectangular. The telescopic shaft and the limiting strip are respectively slidably sleeved in the cylindrical section and the rectangular section of the limiting sliding groove. A spring is fixedly connected to the outside of the top of the telescopic shaft and located outside the limiting strip.

[0009] Furthermore, fixing blocks are fixedly installed on the outer ring of the telescopic shaft in a ring shape and evenly. A ramming rod passes through the middle of the fixing block movably. A limiting cavity is formed inside the fixing block. A limiting magnetic ring is fixedly installed at the position where the outer ring of the ramming rod is inside the limiting cavity.

[0010] Furthermore, an annular magnet is fixedly installed above the limiting cavity inside the fixing block.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting that the spiral joint is threadedly sleeved with the bottom of the storage bin and adjustable, compared with the prior art, the bottom height of the spiral joint can be adjusted to adapt to unloading under different conditions. At the same time, a rotating cylinder is rotatably sleeved inside the spiral joint, and the rotating cylinder is driven by a motor to rotate. In this way, the spiral blade inside the rotating cylinder can be used to achieve uniform and stable feeding, and the feeding speed can also be adjusted according to different situations to avoid too rapid feeding affecting the unloading work.

[0013] 2. By arranging a fixed cylinder sleeving a telescopic shaft inside the storage bin, and fixing blocks and ramming rods are arranged on the outer ring of the telescopic shaft. Compared with the prior art, the annular magnet arranged inside the fixing block repels the limiting magnetic ring on the ramming rod, so that the ramming rod is pressed against and contacts the top of the rotating cylinder. And the top of the rotating cylinder is in a fluctuating state. In this way, the ramming rod can be made to move up and down according to the rotation of the rotating cylinder, and thus the anti-blocking effect can be achieved at the feeding port during feeding.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5, A feed unloading device for a feed mill, comprising a storage bin 1. A spiral joint 2 is threadedly sleeved at the bottom of the storage bin 1. A socket ring groove 201 is provided at the top of the spiral joint 2, and the inner wall of the socket ring groove 201 and the outer circle at the bottom of the storage bin 1 are provided with adapted threads. The spiral joint 2 is threadedly sleeved on the bottom end of the storage bin 1 through the socket ring groove 201. In this way, the height of the bottom of the spiral joint 2 can be adjusted by the spiral depth of the socket ring groove 201, that is, it can be used to adapt to unloading and bagging in different situations. An electric control valve 3 is arranged inside the bottom end of the spiral joint 2. A drive box 4 is fixedly installed on the outer side of the bottom of the spiral joint 2. A motor 5 is fixedly installed at the top position of the drive box 4 on the outer side of the electric control valve 3. A rotating cylinder 6 is rotatably sleeved inside the inner circle of the spiral joint 2. A spiral blade 7 is arranged inside the inner circle of the rotating cylinder 6. A transmission groove is provided on the outer circle at the bottom end of the spiral blade 7 and communicates with the inside of the drive box 4. The output shaft of the motor 5 extends into the inside of the drive box 4. A transmission belt 8 is sleeved between the outer circle of the output shaft of the drive box 4 and the transmission groove at the bottom end of the spiral blade 7. The bottom end of the rotating cylinder 6 has a larger diameter and is rotatably sleeved inside the spiral joint 2. At the same time, this socket is communicated with the inside of the drive box 4. In this way, the motor 5 can be used to drive and drive the rotating cylinder 6 to rotate synchronously. At the same time, structures such as gears or chains can also be used for transmission. A fixed cylinder 9 is fixedly installed in the middle of the inner top wall of the storage bin 1. A limit sliding groove 901 is provided inside the fixed cylinder 9. A telescopic shaft 10 is movably sleeved at the bottom of the limit sliding groove 901, and the telescopic shaft 10 extends into the middle of the spiral blade 7. A cylindrical groove is provided in the middle of the spiral blade 7 and extends to the bottom to form an abutting groove 701. The bottom end of the telescopic shaft 10 abuts against the abutting groove 701. When the rotating cylinder 6 rotates, it will drive the spiral blade 7 to rotate. At this time, the spiral blade 7 spirally drives the feed to be conveyed downward. At this time, the telescopic shaft 10 cannot rotate, so there will be no interference. At the same time, the bottom end of the telescopic shaft 10 abuts against the abutting groove 701. In this way, when installing and adjusting the spiral joint 2, the abutting groove 701 will press against the telescopic shaft 10 and compress the telescopic shaft 10 to contract into the limit sliding groove 901. A limit strip 11 is fixedly connected to the top of the telescopic shaft 10. The bottom of the limit sliding groove 901 is cylindrical and the top is rectangular. The telescopic shaft 10 and the limit strip 11 are respectively slidably sleeved in the cylindrical section and the rectangular section of the limit sliding groove 901. A spring 16 is fixedly connected to the outer circle of the top of the telescopic shaft 10. The telescopic shaft 10 can be limited by the limit sliding groove 901, and at the same time, the telescopic shaft 10 is allowed to expand and contract up and down. In this way, it will not only not affect the feeding of the spiral blade 7, but also make the relative position of the telescopic shaft 10 and the rotating cylinder 6 as a whole unchanged, that is, the fixed block 12 is located above the rotating cylinder 6, and anti-blocking during feeding can be realized.

[0024] Please refer to Figures 2 - 7, a fixed block 12 is evenly and fixedly installed in a ring shape on the outer ring of the telescopic shaft 10. A ramming rod 13 is movably sleeved through the middle of the fixed block 12. A limiting cavity 1201 is formed inside the fixed block 12. A limiting magnetic ring 14 is fixedly installed on the outer ring of the ramming rod 13 inside the limiting cavity 1201. The ramming rod 13 can slide up and down when sleeved on the fixed block 12, but is limited by the limiting magnetic ring 14 inside the limiting cavity 1201, so that the up and down sliding range of the ramming rod 13 is certain. An annular magnet 15 is fixedly installed above the limiting cavity 1201 inside the fixed block 12. The magnetic poles of the opposite surfaces of the limiting magnetic ring 14 and the annular magnet 15 are the same. The top of the rotary drum 6 is in a undulating state along a circle. Such a setting makes the limiting magnetic ring 14 located at the bottom position of the limiting cavity 1201 under the action of magnetic repulsion in the normal state. When the rotary drum 6 rotates, the top will rotate synchronously. At this time, the bottom of the ramming rod 13 is in pressing contact with the top surface of the rotary drum 6, and the ramming rod 13 will be pushed up along the undulation of the top of the rotary drum 6. Then, when it continues to rotate, the ramming rod 13 will move downward under the action of magnetic repulsion. Therefore, an action of the ramming rod 13 moving up and down continuously is formed to prevent the feeding port of the storage bin 1 from being blocked.

[0025] Working principle: During operation, first connect the spiral joint 2 to the storage bin 1 as required and adjust it to the required height. At this time, the top of the abutting groove 701 abuts against the bottom of the telescopic shaft 10 and compresses it into the limiting sliding groove 901. Then, open the electric control valve 3 and start the motor 5 at the same time. The motor 5 drives the transmission belt 8 to rotate synchronously and drives the rotary drum 6 to rotate. When the rotary drum 6 rotates, it drives the spiral blade 7 to rotate synchronously, so that the feed in the storage bin 1 is conveyed downward along the spiral blade 7 and loaded into the required container or bag;

[0026] Meanwhile, when discharging, the rotary drum 6 keeps rotating, and the contact height between the top of the rotary drum 6 and the ramming rod 13 also continuously changes. That is, when the ramming rod 13 abuts against the lowest point of the top surface of the rotary drum 6, the magnetic force of the annular magnet 15 just makes the limiting magnetic ring 14 located at the bottom of the limiting cavity 1201. When the ramming rod 13 abuts against the highest point of the top surface of the rotary drum 6, the limiting magnetic ring 14 is just driven to move upward to the top of the limiting cavity 1201. Such a cyclic rotation in sequence forms an up and down movement action to move the feed at the discharging port at the bottom of the storage bin 1 and prevent it from being blocked and affecting the discharging.
