Description

Technical Field

[0001] The present invention relates to the technical field of feed processing, and specifically relates to a multifunctional pig feed processing device. Background Art

[0002] Pig feed is usually composed of protein feed, energy feed, roughage, green feed, silage, mineral feed, and feed additives for raising domestic pigs. When processing pig feed, it is necessary to mix raw materials. The raw materials are generally stored inside feed bags. When mixing the raw materials, it is necessary for workers to carry different raw materials into the mixing device manually, and manually cut open the feed bags. Only after cutting can the raw materials inside the feed bags be poured into the mixing device. Manually cutting open the feed bags is rather troublesome.

[0003] In response to the above problems, Chinese Patent: CN202311628458.7 discloses a pig feed processing device, including a centralized rack. The surface of the centralized rack is fixedly connected with an electric lifting rack. The top of the centralized rack is fixedly connected with a sealing ring. A top cover is arranged on the top of the centralized rack, and the top of the top cover is fixedly connected with the electric lifting rack. The bottom of the centralized rack is communicated with a mixing rack, and the bottom of the centralized rack is fixedly connected with legs. After the motor of the present invention is powered on, the cutting assembly rotates inside the centralized rack driven by the motor, and the feed bag is cut open by the cutting assembly, so that the raw materials can enter the mixing rack through the sieve plate for mixing. A stirring component is arranged inside the centralized rack, and the raw materials are stirred by the stirring component to move on the surface of the sieve plate, avoiding the accumulation of raw materials on the surface of the sieve plate. The mixing rack mixes and processes the raw materials through the rotation of the rotating rod, and the sealing plate separates from the inner wall of the mixing rack through the electric rod.

[0004] Although the above patent can cut open the feed bag by using the cutting assembly and use the sieve plate for feeding, although the hook is used to pull the feed bag to separate it from the feed inside, the bag still remains above the sieve plate after being separated from the material, and it is necessary to frequently stop the machine for manual cleaning, interrupting the continuity of production. Especially in high-frequency processing, the accumulated downtime leads to a decrease in production capacity. Moreover, a linkage structure for realizing vibrating feeding is arranged inside it. The above device is used for feeding and mixing feed raw materials. The complex linkage structure needs to be regularly cleaned after long-term use, otherwise it may get stuck.

[0005] Therefore, we propose a multifunctional pig feed processing device. Summary of the Invention

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Example 1: Please refer to Figures 1 - 3, the present invention provides a technical solution: a multifunctional pig feed processing device, including a mixing tank 1. A mixing mechanism is arranged inside the mixing tank 1. The mixing mechanism includes a motor and a mixing shaft connected to the motor. The connection structure between the motor and the mixing shaft is prior art and will not be elaborated here. The raw materials for making feed are evenly mixed inside the mixing tank 1. An outlet is arranged at the bottom of the mixing tank 1. The evenly mixed raw material mixture is discharged through the outlet at the bottom and then collected, and can be conveyed to the next process through a conveyor belt 3.

[0036] A fixed cylinder 2 is fixedly connected to the top of the mixing tank 1. The fixed cylinder 2 is concentric with the mixing tank 1. A conveyor belt 3 is arranged outside the mixing tank 1. The top of the conveyor belt 3 is located above the fixed cylinder 2. The raw materials are transported to above the fixed cylinder 2 through the conveyor belt 3, and then fall into the fixed cylinder 2 due to their movement inertia and gravity. A placement rack 4 is movably arranged inside the fixed cylinder 2. A cutting assembly 5 and a spreading assembly 6 are arranged below the placement rack 4. A driving rack 7 is movably arranged inside the fixed cylinder 2. A dispersing rack 8 is movably arranged on the driving rack 7. A negative pressure collection tank 9 is also arranged on one side of the fixed cylinder 2.

[0037] Example 2: Please refer to Figures 3 - 12 , both the cutting assembly 5 and the spreading assembly 6 are located at the central position of the fixed cylinder 2. When the feed bag is transported into the fixed cylinder 2 by the conveyor belt 3, the feed bag falls onto the placement rack 4, and then drives the placement rack 4 to move downward under its own weight, so that the bottom of the feed bag contacts the cutting assembly 5, thereby cutting open the bottom of the feed bag to achieve feeding. At the same time, the spreading assembly 6 can spread open the cut part of the feed bag to facilitate feeding. When feeding, in order to facilitate the mixing tank 1 to fully mix various raw materials during mixing, a dispersing rack 8 is also arranged on the driving rack 7. When the material is fed through the dispersing rack 8, the dispersing rack 8 can rotate to evenly distribute the material in the mixing tank 1, making the mixing effect better when the mixing tank 1 is mixing. When the material in the feed bag is completely fed, the negative pressure collection tank 9 can collect the remaining bags to prevent the bags from still being inside the fixed cylinder 2 and affecting subsequent operations. Since the positions of the cutting assembly 5 and the spreading assembly 6 are both at the center of the fixed cylinder 2, the conveying speed of the conveyor belt 3 needs to be adjusted so that the conveyor belt 3 can transport the feed bag into the placement rack 4 when transferring it. In actual use, the conveying speed of the conveyor belt 3 can be adjusted according to the actual weight of the material.

[0038] The inside of the negative pressure collection tank 9 is under negative pressure, and thus can suck the remaining bags after feeding into its interior. However, in order to prevent the negative pressure collection tank 9 from also collecting the material into its interior, a valve is arranged at its inlet. On the one hand, the valve can control its opening and closing, and thus is opened after the material in the feed bag is completely fed. On the other hand, it can also prevent the feed raw materials from being sucked into its interior. The valve and its control mechanism are both prior art and will not be elaborated here.

[0039] The placement rack 4 includes a fixed frame 41. A plurality of cross bars 42 are fixedly arranged inside both sides of the fixed frame 41. The cross bars 42 on both sides can support the two ends of the feed bag placed thereon. Thus, while ensuring the support of the feed bag, the bottom of the feed bag can be exposed to facilitate the operation of the cutting assembly 5 and the spreading assembly 6. The length of the cross bar 42 can be adjusted specifically according to the size of the feed bag. Based on this requirement, the cross bar 42 can be installed on the fixed frame 41 through bolts. Thus, during adjustment, only the bolts need to be disassembled, and then the cross bar 42 can be conveniently replaced. An ear plate 43 is fixedly arranged on the outer side of the fixed frame 41. An air cylinder 10 is fixedly arranged inside the fixed cylinder 2. A piston 11 is slidably arranged inside the air cylinder 10. A moving rod 12 is arranged at the top of the piston 11. The top end of the moving rod 12 is connected to the ear plate 43. A support spring 13 is arranged on the outer side of the moving rod 12. The upper and lower ends of the support spring 13 are respectively connected to the ear plate 43 and the air cylinder 10.

[0040] An air outlet one-way valve is arranged at the bottom of the air cylinder 10. Air inlet one-way valves are arranged on both the outer side of the bottom and the outer side of the middle of the air cylinder 10, and the air inlet of the air inlet one-way valve located on the outer side of the bottom is smaller than that of the other air inlet one-way valve.

[0041] When the feed bag is transported to the placement rack 4 by the conveyor belt 3, under the action of its own weight, it will drive the placement rack 4 to move downward. The placement rack 4 drives the moving rod 12 and the piston 11 to move downward through the ear plate 43. When the piston 11 moves downward, it can discharge the air in the air cylinder 10 and compress the support spring 13 at the same time. At this time, the support spring 13 is in a compressed state. The gas in the air cylinder 10 is discharged through the one-way air outlet valve at its bottom. When the feed bag moves downward, its bottom will be cut by the cutting assembly 5, and the internal material will gradually discharge. When the internal material, that is, the raw material, gradually discharges, its own weight gradually becomes smaller. Therefore, it cannot drive the placement rack 4 to move to the bottommost position. However, the cutting assembly 5 requires a certain process when working, that is, it is not completed instantaneously. Therefore, in order to avoid the problem that the placement rack 4 immediately resets after moving to the bottommost position, a one-way air inlet valve is provided on the outer side of the bottom of the air cylinder 10. When the material in the feed bag gradually discharges, at this time, its own weight cannot overcome the elastic force of the support spring 13, and the support spring 13 needs to reset. Then, it drives the fixed frame 41 to move through the ear plate 43, and further drives the piston 11 to move upward by the moving rod 12. However, since all the air in the air cylinder 10 has been discharged at this time, the cavity between the piston 11 and the air cylinder 10 needs to inhale air to balance the air pressure, so that the piston 11 moves upward. At this time, the air inlet of the one-way air inlet valve is adjusted specifically according to the operation time of the cutting assembly 5, so that the piston 11 slowly resets in the air cylinder 10, and then the placement rack 4 slowly resets until the cutting assembly 5 completes the operation and all the materials in the feed bag are completely discharged. At this time, the piston 11 moves to the position of another one-way air inlet valve, and the air inlet of this one-way air inlet valve is large enough to enable the piston 11 to reset quickly, meeting the feeding requirements and increasing its reset speed.

[0042] The cutting assembly 5 includes a fixed frame 51 fixedly arranged in the fixed cylinder 2. The fixed frame 51 is elliptical, and its long end corresponds to both sides of the placement rack 4. A plurality of cutting guide rods 52 are fixedly connected to the inner side of the fixed frame 51. A fixed disk one 53 is arranged at the end of the cutting guide rod 52. A cutting slider 54 is slidably arranged on the outer side of the cutting guide rod 52. A cutting blade 55 is fixedly arranged on the cutting slider 54. When the cutting slider 54 moves, it can drive the cutting blade 55 to move. The cutting guide rod 52 plays a guiding role in it, making the cutting blade 55 move more stably when moving. The cutting blade 55 is triangular, and one of its side tips faces upward, so that the feed bag can be broken when it abuts against its end. In this embodiment, the number of cutting blades 55 is set to four, and the angle between two adjacent cutting blades 55 is ninety degrees. In the initial state, the backs of the plurality of cutting blades 55 abut against each other to form a four-wing structure with a tip. When the feed bag falls, this tip pierces the feed bag, and then the plurality of cutting blades 55 move away from each other to cut the bottom of the feed bag, realizing feeding. A first reset spring 56 is arranged on the outer side of the cutting guide rod 52. Both ends of the first reset spring 56 are connected to the cutting slider 54 and the fixed disk one 53 respectively.

[0043] The expansion assembly 6 includes a plurality of expansion guide rods 61 arranged on the inner side of the fixed frame 51, a fixed plate 62 is arranged at the end of the expansion guide rod 61, and an expansion slider 63 is slidably arranged on the outer side of the expansion guide rod 61, and the expansion guide rod 61 plays a guiding role for the expansion slider 63, and an expansion rod 64 is fixedly connected to the expansion slider 63, and the top of the expansion rod 64 is lower than the top tip of the cutting blade 55, and the number of the expansion rods 64 is set the same as the cutting blade 55, and the position of the expansion rod 64 is at the angle between two adjacent cutting blades 55. When the cutting blade 55 moves to cut the bottom of the feed bag, the expansion rods 64 will also move away from each other to expand the bottom of the bag, which is convenient for unloading and can assist the material located at the four corners of the feed bag to detach, and a return spring 65 is arranged on the outer side of the expansion guide rod 61, and the two ends of the return spring 65 are respectively connected to the expansion slider 63 and the fixed plate 62.

[0044] The expansion rod 64 is hollow inside and has an air jet hole 66 on the outside of the top. The direction of the air jet hole 66 faces outward, that is, when the expansion rod 64 opens the bottom of the bag, the air jet hole 66 faces the four corners inside the bag, thereby assisting the airflow to facilitate the smooth discharge of materials at the four corners inside the bag. The bottom end of the expansion rod 64 is connected to an air pump through a pipeline, wherein the air pump is not drawn in the figure.

[0045] The fixed cylinder 2 is provided with a driving cylinder 14, and the output end of the driving cylinder 14 is connected to the driving frame 7. A plurality of cables 15 are provided on the driving frame 7. One end of the cable 15 is fixedly connected to the driving frame 7, and the other end is connected to the cutting slider 54 or the stretching slider 63. The driving cylinder 14 can drive the driving frame 7 to move, thereby making the driving frame 7 away from the fixed frame 51. When the driving frame 7 moves, the cable 15 is pulled, and then the cutting slider 54 and the stretching slider 63 are pulled to move by the cable 15. That is, when the feed bag falls on the placement rack 4, the placement rack 4 moves down to make the feed bag abut against the cutting blade 55. At this time, the driving cylinder 14 is started to drive the driving frame 7 to move down, and then the cutting blade 55 is driven to move through the cable 15 to cut the bottom of the bag. At the same time, the expansion rod 64 also moves to open the bottom opening of the bag. When the unloading is completed, the driving cylinder 14 is reset. Under the action of the reset spring 1 56 and the reset spring 2 65, the cutting blade 55 and the expansion rod 64 are reset to facilitate the next operation.

[0046] A spiral rod 16 is fixedly arranged inside the fixed cylinder 2, a mounting ring 17 is fixedly arranged inside the driving frame 7, and the dispersion frame 8 includes a spiral sleeve 81 rotatably arranged inside the mounting ring 17, and the spiral sleeve 81 is sleeved on the outside of the spiral rod 16. When the spiral sleeve 81 moves up and down along the spiral rod 16, the spiral sleeve 81 will rotate. A plurality of dispersion rods 82 are fixedly arranged on the outside of the spiral sleeve 81. The interior of the spiral rod 16 is hollow and the bottom end is connected to the air pump through a pipeline. A plurality of dispersion air holes 83 are opened on the outside of the top of the spiral rod 16.

[0047] When the driving cylinder 14 drives the driving frame 7 to move downward, the driving frame 7 drives the screw sleeve 81 to move downward through the mounting ring 17. Then, the screw sleeve 81 moves downward along the screw rod 16, causing the screw sleeve 81 to drive the dispersing rod 82 to rotate. The materials falling from the bottom of the bag mouth are knocked into the interior of the mixing tank 1 by the dispersing rod 82 and are relatively evenly dispersed, making the mixing effect of the mixing tank 1 better. Moreover, a plurality of dispersing air holes 83 are provided on the outer side of the top of the screw rod 16, and the dispersing effect during the feeding of the materials can be further enhanced by the assistance of air flow, achieving the effect of uniform feeding.

[0048] A negative pressure collecting tank 9 is provided with a negative pressure pipe 18 at the top. The negative pressure pipe 18 extends above the fixed cylinder 2, and the empty bag after feeding can be sucked into the negative pressure collecting tank 9 along the negative pressure pipe 18.

[0049] In summary, the conveyor belt 3 transports the feed bag above the fixed cylinder 2, and uses inertia and gravity to make the feed bag fall into the concentrically arranged fixed cylinder 2. The two ends of the bag body are supported by the cross bar 42 of the placing rack 4, and the bottom is exposed to the cutting assembly 5 and the expanding assembly 6. When the self-weight of the feed bag presses the placing rack 4 to move downward, the air cylinder 10 exhausts air to trigger the compression of the support spring 13. At the same time, the cutting blade 55 slides along the guide rod to pierce the bottom of the bag, forming a four-wing cut structure. The expanding rod 64 moves outward synchronously to expand the bag mouth. The air injection holes 66 at its top inject air flow through the air pump to assist the materials at the four corners to fall off. The driving frame 7 pulls the cable 15 under the action of the air cylinder to control the operation of the cutting / expanding assembly 6, and at the same time drives the screw sleeve 81 to rotate along the screw rod 16, so that the dispersing rod 82 evenly scatters the falling materials into the mixing tank 1. The dispersing air holes 83 at the top of the screw rod 16 further strengthen the air flow dispersing effect. After the feeding is completed, the negative pressure collecting tank 9 sucks away the empty bag through valve control. The placing rack 4 slowly resets under the adjustment of the air inlet one-way valve of the air cylinder 10 to ensure the complete operation of the cutting assembly 5. The entire system realizes the integrated operation of the whole process of automatic bag breaking, uniform dispersion, mixing and stirring of raw materials, and waste material recovery through mechanical linkage, pneumatic regulation and air flow assistance.

[0050] Embodiment 3: Please refer to Figure 13 , the present invention provides a technical solution: on the basis of Embodiment 2, one end of the negative pressure pipe 18 close to the fixed cylinder 2 is a corrugated section, and an extension cylinder 19 is provided on the outer side of the negative pressure pipe 18. The fixed end of the extension cylinder 19 is connected to the fixed section of the negative pressure pipe 18, and the output end of the extension cylinder 19 is connected to the corrugated section of the negative pressure pipe 18.

[0051] In order to further ensure the attraction effect on empty bags and prevent the suction of materials, in this embodiment, the end of the negative pressure pipe 18 is set as a telescopic corrugated structure. In this way, when attracting an empty bag, the extension cylinder 19 can drive the negative pressure pipe 18 to extend to the top of the empty bag and abut against its outer wall, so that the empty bag can be quickly and accurately sucked away. After the empty bag is sucked away, the end of the negative pressure pipe 18 resets and the internal valve body closes to prevent the suction of materials into it.

[0052] 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 comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0053] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
