Description

TECHNICAL FIELD

[0002] In the granular premix feed processing technical field, the prior art has many problems to be solved, which seriously affects the quality and efficiency of feed processing, mainly reflected in the following aspects:

[0003] Firstly, the mixing system design of the existing feed processing device has obvious defects, the current technology adopts the simple structure of single mixing frame to realize the mixing and conveying of feed, this single mechanical stirring method has many limitations, because the contact area of the mixing frame is limited, it is impossible to realize the full contact and uniform mixing of materials in a short time, which leads to low mixing efficiency, at the same time, the single stirring method is also difficult to break the stratification phenomenon between different density raw materials, resulting in poor mixing uniformity, uneven distribution of various nutrients, which seriously affects the quality standard of finished feed, this simple mixing method not only prolongs the production cycle, but also may lead to uneven feed composition, affecting the growth and development of breeding animals.

[0004] Secondly, although part of the improved equipment introduces a high-pressure gas auxiliary mixing system, it tries to improve the mixing efficiency by air stirring, but these devices still have major defects in gas delivery control, these devices usually adopt a fixed-parameter gas delivery system, which cannot flexibly adjust the air flow intensity according to different material characteristics and production needs, when processing raw materials with different particle size, density or water content, due to the inability to adjust the air flow speed, it may cause problems such as scattering of fine particle materials or deposition of large particle materials, this rigid air flow control method not only affects the mixing effect, but also may cause material loss and reduce production efficiency.

[0005] More seriously, although some devices have increased the air flow speed adjustment function in design, trying to realize the adjustable control of high-pressure gas delivery speed through mechanical structure, but these improved designs still have major defects, and face serious stability problems in actual use, first of all, high-pressure gas will produce strong impact force in the conveying process, this continuous impact will cause great pressure on the adjustment structure; secondly, the device will produce continuous mechanical vibration during operation, under the continuous action of these external forces, the simple adjustment structure is easy to loosen, and the connection part may gradually displace, more seriously, once the adjustment structure is offset, not only will the preset air flow parameter change, but also may cause unstable air flow intensity, affecting the mixing effect, this instability of parameters not only reduces the production efficiency, but also may lead to substandard product quality, causing serious economic losses to production.

[0032] Linkage pipe 9 side wall is provided with a plurality of linkage holes 21, and a plurality of linkage holes 21 are arranged in spiral array on the side wall of linkage pipe 9, and linkage hole 21 is arranged at the position without linkage groove 13.

[0033] Fixed rod 22 is fixedly arranged in adjusting sleeve 7, and movable sleeve 23 is fixedly connected to the inner side of fixed rod 22, and movable rod 24 is slidably arranged in movable sleeve 23, and movable rod 24 is fixedly connected to one end of linkage lever 10.

[0035] A plurality of lock rods 27 are slidably arranged on the side wall of adjusting sleeve 7, and reset spring 28 is arranged on the outer side of adjusting sleeve 7, and a plurality of lock grooves 29 are arranged on the outer wall of connecting pipe 8, one end of lock rod 27 is connected with the outer wall of adjusting sleeve 7 through reset spring 28, and the other end of lock rod 27 is inserted into lock groove 29.

[0036] In this embodiment, when it is necessary to adjust the airflow speed and intensity, the control sleeve 17 is first rotated clockwise, causing the control sleeve 17 to drive the active wheel 16 on one side to rotate.

Since the screw sleeve 18 and the screw 19 are connected by threads, and the screw 19 is fixedly connected to one side of the locking sleeve 20, the screw 19 drives the locking sleeve 20 to slide. The locking sleeve 20 drives the slider 26 to slide along the slide groove 25. Then, the locking sleeve 20 no longer locks the locking rod 2. 7. Limit the movement, then rotate the adjusting sleeve 7. The adjusting sleeve 7 will drive the multiple locking rods 27 sliding on the outer wall to rotate. Then, the inner wall of the locking groove 29 will press one end of the locking rod 27. Due to the rounded corner design at the end of the locking rod 27 and the edge of the locking groove 29, one end of the locking rod 27 will slide out of the locking groove 29, and the other end of the locking rod 27 will drive the return spring 28 to stretch. At the same time, the adjusting sleeve 7 will drive the moving sleeve 23 to rotate through the fixed rod 22. Then, the moving sleeve 23 will drive the inner movable rod 24 to rotate. Then, the movable rod 24 will drive the linkage rod 10 connected at one end to rotate. Then, the linkage rod 10 The linkage bar 11 on the outer wall will slide along the linkage groove 13. Due to the spiral structure design of the linkage bar 11 and the linkage groove 13, the linkage rod 10 will drive the movable rod 24 to slide along the moving sleeve 23. The number of linkage holes 21 on the side wall of the linkage tube 9 blocked by the linkage rod 10 will change, causing the gas passage volume to change, thereby achieving the purpose of adjusting the airflow speed and airflow intensity. After the adjustment is appropriate, the rotation of the adjusting sleeve 7 will stop, and the return spring 28 will drive the locking rod 27 to slide and reset. Then, one end of the locking rod 27 will be inserted into the corresponding lock. In groove 29, the control sleeve 17 is rotated in the opposite direction. The control sleeve 17 drives the screw sleeve 18 to rotate through the cooperation of the driving wheel 16 and the driven wheel 15. Due to the threaded cooperation between the screw sleeve 18 and the screw 19, the screw 19 drives the locking sleeve 20 to slide and reset. The locking sleeve 20 drives the slider 26 to slide and reset along the sliding groove 25. Then, the inner wall of the locking sleeve 20 limits the outer end of the locking rod 27, so that the locking rod 27 will not move. Then, the locking rod 27 and the locking groove 29 cooperate to limit the adjusting sleeve 7, so that the adjusting sleeve 7 cannot rotate, thereby ensuring structural stability and ensuring the stable use of the equipment.

[0037] Please see Figures 1-3 As a further implementation of the overall equipment: a feeding bin 30 is fixedly provided at the top of the mixing bin 1, a sealing cover 31 is detachably provided at the top of the feeding bin 30, and multiple through holes 32 are provided on the mixing frame 6.

[0038] A material conveying bin 33 is connected below the mixing bin 1. A processing bin 34 is connected to one side of the material conveying bin 33. A discharge plate 35 is detachably provided on one side of the processing bin 34. An exhaust port 36 is provided at the top of the processing bin 34.

[0039] A first motor 37 is detachably installed on one side of the mixing chamber 1, and a second motor 38 is installed on one side of the processing chamber 34. Both the output ends of the first motor 37 and the second motor 38 are connected to a reducer 39. The output end of the reducer 39 connected to the output end of the second motor 38 is connected to a tilting plate 40. The tilting plate 40 is rotatably installed in the processing chamber 34.

[0040] More specifically, when the equipment is needed, first remove the sealing cover 31, then add the feed to be premixed into the mixing chamber 1 through the feed hopper 30, then turn on the first motor 37. After being reduced in speed by the reducer 39, the output of the first motor 37 drives the mixing frame 6 to rotate. Due to the spiral structure design of the mixing frame 6, the mixing frame 6 will mix the feed while conveying it. Then, reinstall the sealing cover 31 on the top of the feed hopper 30, then turn on the air pump 2, so that the air pump 2 compresses the gas and delivers it to the two connecting chambers 4 through the conveying pipe 5 and connecting pipe 8, etc. Then, it is delivered to the mixing chamber 1 through multiple nozzles 3 connected to one side of the connecting chamber 4 for convective impact and agitation of the feed. At the same time, the gas will pass through the mixing frame 6. The through-hole 32 allows for flow, improving the mixing effect and accelerating the mixing efficiency. The pre-mixed feed then falls into the processing chamber 34 through the conveyor connected to one end of the mixing chamber 1. The airflow also carries the feed into the processing chamber 34, and then the airflow is discharged through the exhaust port 36. At this time, the second motor 38 is turned on, and the output end of the second motor 38 drives the tipping frame to rotate after being reduced by the reducer 39. The tipping frame then drives the feed in the processing chamber 34 to be mixed again to ensure the uniformity of the mixture. After the final mixing, the discharge plate 35 is removed, and the mixed feed in the processing chamber 34 falls into the external collection device through the discharge port. Finally, all drive components are turned off, and the discharge plate 35 is reinstalled in its original position.

[0041] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the airflow speed and intensity, firstly, rotate the control sleeve 17 clockwise, causing the control sleeve 17 to drive the active wheel 16 on one side to rotate. Then, the active wheel 16 will drive each meshing driven wheel 15 to rotate. Then, the driven wheel 15 will drive the screw sleeve 18 to rotate. Since the screw sleeve 18 and the screw 19 are connected by threads, and the screw 19 is fixedly connected to one side of the locking sleeve 20, the screw 19 will drive the locking sleeve 20 to slide. The locking sleeve 20 will then drive the slider 26 to slide along the slide groove 25. Then, the locking sleeve 2... The locking rod 27 is no longer limited. Then, the adjusting sleeve 7 is rotated, causing multiple locking rods 27 slidably mounted on the outer wall to rotate. The inner wall of the locking groove 29 then presses against one end of the locking rod 27. Due to the rounded corners at the end of the locking rod 27 and the edge of the locking groove 29, one end of the locking rod 27 slides out of the locking groove 29, and the other end of the locking rod 27 stretches the return spring 28. Simultaneously, the adjusting sleeve 7 rotates the moving sleeve 23 via the fixed rod 22. The moving sleeve 23 then rotates the inner movable rod 24, which in turn rotates the connecting rod 10 connected to one end. The linkage rod 10 drives the linkage bar 11 on the outer wall to slide along the linkage groove 13. Due to the spiral structure design of the linkage bar 11 and the linkage groove 13, the linkage rod 10 then drives the movable rod 24 to slide along the moving sleeve 23. The number of linkage holes 21 on the side wall of the linkage tube 9 blocked by the linkage rod 10 changes, causing a change in the gas passage volume, thereby achieving the purpose of adjusting the airflow speed and airflow intensity. After the adjustment is appropriate, the rotation of the adjusting sleeve 7 stops, and the return spring 28 drives the locking rod 27 to slide and reset. Then, one end of the locking rod 27 will be inserted into the corresponding... In the locking groove 29, the control sleeve 17 is rotated in the opposite direction. The control sleeve 17 drives the screw sleeve 18 to rotate through the cooperation of the driving wheel 16 and the driven wheel 15. Due to the threaded cooperation between the screw sleeve 18 and the screw 19, the screw 19 drives the locking sleeve 20 to slide and reset. The locking sleeve 20 drives the slider 26 to slide and reset along the sliding groove 25. Then, the inner wall of the locking sleeve 20 limits the outer end of the locking rod 27, so that the locking rod 27 will not move. Then, the locking rod 27 and the locking groove 29 cooperate to limit the adjusting sleeve 7, so that the adjusting sleeve 7 cannot rotate, thereby ensuring structural stability and ensuring the stable use of the equipment.

[0042] When the equipment is needed, first remove the sealing cover 31, then add the feed to be premixed into the mixing chamber 1 through the feed hopper 30, then turn on the first motor 37. After being reduced in speed by the reducer 39, the output of the first motor 37 drives the mixing frame 6 to rotate. Due to the spiral structure design of the mixing frame 6, the mixing frame 6 will mix the feed while conveying it. Then, reinstall the sealing cover 31 on the top of the feed hopper 30, and then turn on the air pump 2. The air pump 2 compresses the gas and delivers it to the two connecting chambers 4 through the conveying pipe 5 and connecting pipe 8, etc. Then, it delivers the gas to the mixing chamber 1 through multiple nozzles 3 connected to one side of the connecting chamber 4 to conduct convection impact and disturb the feed. At the same time, the gas will pass through the openings on the mixing frame 6. The feed is circulated through the through-hole 32 to improve the mixing effect and speed up the mixing efficiency. The pre-mixed feed then falls into the processing chamber 34 through the conveyor connected to one end of the mixing chamber 1. The airflow also carries the feed into the processing chamber 34 and then the airflow is discharged through the exhaust port 36. At this time, the second motor 38 is turned on, and the output end of the second motor 38 drives the tipping frame to rotate after being slowed down by the reducer 39. The tipping frame then drives the feed in the processing chamber 34 to be mixed again to ensure the uniformity of the mixture. After the final mixing, the discharge plate 35 is removed, and the mixed feed in the processing chamber 34 falls into the external collection device through the discharge port. Finally, all drive components are turned off, and the discharge plate 35 is reinstalled in its original position.

For all the fixed connections mentioned above, welding is preferred.
