Description

Technical Field

[0001] This utility model relates to the field of feed additive processing technology, specifically a mixed feed additive crushing and mixing device. Background Technology

[0002] In the process of feed production and processing, in order to enhance the nutritional value of basic feed, improve animal production performance, ensure animal health, save feed costs, and improve the quality of livestock products, it is usually necessary to add different kinds of additives to the feed. Before adding them, it is necessary to use appropriate equipment to crush and mix the different kinds of additives.

[0003] CN219964991U discloses a mixed feed additive pulverizing and mixing device, including a mixing chamber and a pulverizing bin. The pulverizing bin contains meshing main and driven pulverizing rollers. Starting a pulverizing motor drives the main and driven rollers to rotate, pulverizing the added additives. A stirring shaft is rotatably mounted inside the mixing chamber, with helical stirring blades fixed on it. Starting a drive motor drives the helical stirring blades to rotate, thereby mixing and conveying the pulverized additives. During the mixing and conveying process, fine particles that meet the requirements fall through a screen to the bottom of the mixing chamber and are discharged through a discharge pipe. Larger particles that do not meet the requirements are lifted through the discharge port and into the pulverizing bin by a lifting component for further pulverization. Integrating pulverization and mixing simplifies the operation process, improves operational efficiency, and allows for further pulverization of large additive particles, improving both the mixing and pulverization effects, thereby improving feed quality.

[0004] Although the technical solution of this patent can pulverize, mix, convey, screen, and reflux pulverize feed additives, it still has some shortcomings in practical application:

[0005] When processing feed additives using the above-mentioned technical solution, the feed additives to be crushed need to be continuously added to the crushing chamber by the workers. Since there is no structure for storing feed additives or any structure for adding feed additives, the feeding operation during the feed additive crushing process is very inconvenient and increases the workload of manual feeding.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example: Figure 1-6 As shown, this utility model provides a mixed feed additive crushing and mixing device, including a mixing chamber 1, a crushing bin 2, a discharge pipe 3, a crushing mechanism 4, a mixing and conveying mechanism 5, and a reflux lifting mechanism 6. The crushing bin 2 is fixedly installed at the upper end of the mixing chamber 1, the discharge pipe 3 is fixedly installed at the bottom of the mixing chamber 1, the crushing mechanism 4 is assembled inside the crushing bin 2, the mixing and conveying mechanism 5 is assembled inside the mixing chamber 1, and the reflux lifting mechanism 6 is assembled on one side of the mixing chamber 1. During the processing of the mixed feed additive, various additives are added to the crushing bin 2, crushed by the crushing mechanism 4, and fall into the mixing chamber 1. Inside the mixing chamber 1, they are stirred, mixed, and conveyed by the mixing and conveying mechanism 5. Additives that meet the particle size requirements are screened by the screen at the bottom of the mixing chamber 1 and discharged outward through the discharge pipe 3. Additives that do not meet the particle size requirements are transported by the mixing conveying mechanism 5 to the return lifting mechanism 6, and then lifted by the return lifting mechanism 6 to the crushing chamber 2 for further crushing. This is the technology disclosed in the comparative case and will not be described in detail here. A storage hopper 7 is fixedly installed on the upper end of the crushing chamber 2. By setting the storage hopper 7, various additives to be crushed can be stored in the storage hopper 7. Two U-shaped fixing frames 71 are fixedly installed on the inner wall of the crushing chamber 2. An L-shaped fixing frame 72 is fixedly installed on the upper end of each of the two U-shaped fixing frames 71. One end of the two L-shaped fixing frames 72 is fixedly connected to the end of the storage hopper 7.

[0032] A feeding bucket 73 is provided between two U-shaped fixing frames 71. The feeding bucket 73 is located below the storage hopper 7. A feeding chute 74 is provided on the feeding bucket 73. Isolation plates 76 are fixedly installed at both ends of the inner wall of the feeding bucket 73, forming a temporary storage chamber 77 between the two isolation plates 76. The feeding chute 74 is connected to the temporary storage chamber 77. By setting up the feeding bucket 73, the feeding chute 74, and the temporary storage chamber 77, the additive in the storage hopper 7 can enter the temporary storage chamber 77 through the feeding chute 74. When the feeding chute 74 on the feeding bucket 73 is vertical... After the feed hopper 77 is tilted downwards, the additives in the temporary storage bin 77 can fall into the crushing bin 2 through the feed chute 74 to achieve feeding. A U-shaped rubber sleeve 75 is fixedly installed at the bottom opening of the storage hopper 7. The lower end face of the U-shaped rubber sleeve 75 is in contact with the outer wall of the feeding barrel 73. The size of the U-shaped rubber sleeve 75 is larger than that of the feed chute 74. By setting the U-shaped rubber sleeve 75, when the feeding barrel 73 rotates, the U-shaped rubber sleeve 75 can improve the sealing between the storage hopper 7 and the feeding barrel 73, and prevent the additives from overflowing.

[0033] A feeding mechanism 8 is provided between the U-shaped fixing frame 71 and the feeding barrel 73. An adjustment component 9 is provided in the feeding barrel 73 and the temporary storage bin 77. By setting the feeding mechanism 8, the feeding mechanism 8 can realize the rotation of the feeding barrel 73, so that the feeding trough 74 is vertically facing or vertically downward, realizing the automatic feeding of additives. By setting the adjustment component 9, the adjustment component 9 can adjust the opening size of the feeding trough 74, thereby realizing the adjustment and control of the amount of additive added.

[0034] The feeding mechanism 8 includes a first rotating shaft 81 and a second rotating shaft 82. One end of the first rotating shaft 81 and the second rotating shaft 82 are fixedly connected to the end of the feeding barrel 73. The other end of the first rotating shaft 81 is rotatably connected to the middle of one of the U-shaped fixing frames 71. The other end of the second rotating shaft 82 is rotatably connected to the middle of the other U-shaped fixing frame 71. By setting the first rotating shaft 81 and the second rotating shaft 82, the feeding barrel 73 can rotate around the axis of the first rotating shaft 81 and the second rotating shaft 82. The other end of the first rotating shaft 81 is fixedly provided with a driven gear 83. By driving the driven gear 83 to rotate, the driven gear 83 can make the feeding barrel 73 rotate through the first rotating shaft 81.

[0035] A servo motor 84 is fixedly mounted on one side of one of the U-shaped brackets 71. An L-shaped mounting bracket 85 is fixedly mounted on the fixed end of the servo motor 84. One end of the L-shaped mounting bracket 85 is fixedly connected to one side of one of the U-shaped brackets 71. A rotating rod 86 is fixedly mounted on the drive output end of the servo motor 84. A half-gear 87 is fixedly mounted on one end of the rotating rod 86. The half-gear 87 is meshed with the driven gear 83. When the servo motor 84 is turned on, the drive shaft of the servo motor 84 can rotate the half-gear 87 through the rotating rod 86. The half-gear 87 can drive the driven gear 83 to rotate.

[0036] The adjusting component 9 includes two control plates 91, which are symmetrically distributed on both sides of the feed trough 74. Each control plate 91 is a curved plate structure and makes movable contact with the wall of the temporary storage bin 77. By setting two control plates 91, the opening size of the feed trough 74 can be adjusted when the two control plates 91 move closer or further apart. An L-shaped plate 922 is fixedly installed on one side of each of the two isolation discs 76. A first connecting shaft 92 is rotatably mounted on one end of each L-shaped plate 922. The first connecting shaft 92 passes through the isolation disc 76 and is coaxial with it. A first connecting rod 921 is fixedly installed on one end of each of the two first connecting shafts 92. One end of each of the two No. 1 connecting rods 921 is fixedly connected to the end of one of the control plates 91. A No. 2 connecting shaft 93 is rotatably installed at the axial center of each of the two isolation discs 76. The No. 1 connecting shaft 92 passes through the No. 2 connecting shaft 93. A No. 2 connecting rod 931 is fixedly installed at one end of each of the two No. 2 connecting shafts 931. One end of each of the two No. 2 connecting rods 931 is fixedly connected to the end of the other control plate 91. By driving the No. 1 connecting shaft 92 and the No. 2 connecting shaft 93 to rotate synchronously in opposite directions, the No. 1 connecting shaft 92 can make one control plate 91 rotate in a circle through the No. 1 connecting rod 921, and the No. 2 connecting shaft 93 can make the other control plate 91 rotate in a circle in the opposite direction synchronously through the No. 2 connecting rod 931.

[0037] One of the first connecting shafts 92 has a first bevel gear 94 fixedly installed at the other end, and one of the second connecting shafts 93 has a second bevel gear 95 fixedly installed at the other end. One of the L-shaped plates 922 has a rotating shaft 96 rotatably mounted at the other end. One end of the rotating shaft 96 has a third bevel gear 961 fixedly installed. The third bevel gear 961 meshes with the first bevel gear 94 and the second bevel gear 95. By driving the rotating shaft 96 to rotate, the rotating shaft 96 can make the third bevel gear 961 rotate. The third bevel gear 961 can make the first connecting shaft 92 and the second connecting shaft 93 rotate synchronously and in opposite directions through the first bevel gear 94 and the second bevel gear 95.

[0038] A worm gear 97 is rotatably mounted on one end of the feeding hopper 73, and a worm wheel 98 is fixedly mounted on the other end of the rotating shaft 96. The worm gear 97 and the worm wheel 98 are meshed and connected. An adjustment knob 99 is fixedly mounted on one end of the worm gear 97. By manually rotating the adjustment knob 99, the worm gear 97 can be rotated, and the worm gear 97 can rotate the rotating shaft 96 through the worm wheel 98.

[0039] Working principle: During the additive crushing process, the operator first adds the additive to be crushed into the storage hopper 7, then turns on the servo motor 84, causing the drive shaft of the servo motor 84 to rotate slowly. The drive shaft of the servo motor 84 causes the half gear 87 to rotate through the rotating rod 86. After the half gear 87 drives the passive gear 83 to rotate 180 degrees, the half gear 87 disengages from the passive gear 83. The passive gear 83 causes the feeding barrel 73 to rotate 180 degrees through the first rotating shaft 81. At this time, the feeding chute 74 is vertically aligned with the bottom opening of the storage hopper 7 (in the default state, the feeding chute 74 is vertically downward). The additive in the storage hopper 7 falls into the temporary storage bin 77 through the feeding chute 74. As the half gear 87 and the passive gear 83 re-mesh, the feeding barrel 73 is driven to rotate 180 degrees again. At this time, the feeding chute 74 is offset from the storage hopper 7 and is vertically downward. The additive in the temporary storage bin 77 falls downward into the crushing bin 2 through the feeding chute 74.

[0040] As the half-gear 87 disengages from the driven gear 83, the additives in the storage hopper 7 automatically fall into the crushing chamber 2, thus facilitating automatic feeding during the feed additive crushing process. This effectively improves the convenience of feeding operations and reduces the intensity of manual labor.

[0041] When it is necessary to adjust the amount of additive added to the crushing chamber 2 each time, with the servo motor 84 off, the operator manually rotates the adjustment knob 99. The adjustment knob 99 causes the worm gear 97 to rotate, which in turn causes the rotating shaft 96 to rotate via the worm wheel 98. The rotating shaft 96 causes the third bevel gear 961 to rotate, which in turn causes the first connecting shaft 92 and the second connecting shaft 93 to rotate synchronously in opposite directions via the first connecting rod 921. The first connecting shaft 92 causes one measuring plate 91 to revolve in a circle, and the second connecting shaft 93 causes another measuring plate 91 to revolve in a circle in the opposite direction via the second connecting rod 931. At this time, the two measuring plates 91 are synchronously approaching or moving away from each other, thereby changing the opening size of the feed trough 74 and controlling the amount added at one time. This conveniently realizes the control of the amount added during the feed additive crushing process, and the single addition amount can be adjusted according to the feed additive crushing process requirements, thus effectively improving flexibility.
