Description

Technical Field

[0001] This utility model relates to the field of feed mixing, and in particular to a twin-shaft paddle mixing device for a feed mixer. Background Technology

[0002] Feed mixers are key equipment in livestock feed processing. They can evenly mix various feed ingredients, improve production efficiency and feed quality, quickly mix different materials, reduce labor costs, and ensure that animals consume nutritionally balanced feed.

[0003] A search revealed that Chinese Patent Publication No. CN207628253U discloses a high-efficiency double-blade mixer for feed, comprising a base, a chamber, and a transmission mechanism. The chamber is located above the base, and the transmission mechanism is located outside the chamber. It also includes a spraying system, which comprises a compressor, a pressure vessel, pipes, an oil valve, and a nozzle. The compressor is located at the top of the pressure vessel, and the pressure vessel is connected to the oil valve via pipes. The oil valve is connected to the nozzle via pipes.

[0004] The aforementioned patent specification mentions that "the dual-blade high-efficiency feed mixer improves the transmission mechanism and spraying system." While the patent achieves high uniformity in oil spraying and feed mixing, it lacks sieving and testing of the stirred feed, making it impossible to remove impurities. This results in the presence of harmful substances that endanger animal health. Furthermore, the inconsistent particle size affects feed intake and digestibility. Therefore, a dual-shaft blade mixing device for the feed mixer is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dual-shaft paddle mixing device for a feed mixer, which aims to improve the problem in the prior art where the brush plate is designed in a straight line. When it comes into contact with garbage on the road in front, the garbage is difficult to push to the sides and thus accumulates on the front side of the brush plate, making it difficult for the device to move forward normally.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dual-shaft paddle stirring device for a feed mixer, comprising a bottom box, a screening mechanism installed on the inner wall of the bottom box, a support box fixedly connected to the outside of the bottom box, a stirring mechanism fixedly connected to the top of the bottom box, a drive mechanism installed on the outside of the stirring mechanism, and a quantity control mechanism installed on the top of the stirring mechanism.

[0007] The screening mechanism includes a feeding plate, the outer side of which is fixedly connected to the inner wall of the base box. A screen plate is rotatably connected to the inner wall of the base box. A movable ball is rotatably connected to the bottom of the screen plate. A connecting rod is rotatably connected to the outer side of the movable ball. A linkage assembly is installed on the inner wall of the support box. A rotating disk is fixedly connected to the outer side of the linkage assembly. A movable rod is fixedly connected to the bottom of the rotating disk. The outer side of the movable rod is movably connected to the inner wall of the connecting rod.

[0008] Furthermore, the screening mechanism is used to screen the stirred feed, allowing the stirring effect to be detected and enabling the feed to be consumed by different types of organisms at a more suitable size. The support box is used to fix the position of the internal linkage components. The stirring mechanism adopts a dual-shaft stirring method, which makes the feed mixing more uniform. The drive mechanism is used to provide driving force, and the quantity control mechanism is used to control the amount of feed being stirred. The feed plate is used to limit the feed diameter, so that the screening range is standardized. The drive of the linkage components drives the rotating disk to rotate. The rotation of the rotating disk drives the movable rod to rotate around the center of the rotating disk, so that the movable rod drives the connecting rod to change position. The connecting rod drives the movable ball to change position, which pulls the screen plate to shake, thereby realizing screening.

[0009] As a further description of the above technical solution:

[0010] The linkage component includes a first bevel gear, a linkage shaft rotatably connected to the inner wall of the support box, a second bevel gear fixedly connected to the top of the linkage shaft, the second bevel gear being meshed with the first bevel gear externally, and the bottom of the linkage shaft being fixedly connected to the top of the rotating disk.

[0011] Furthermore, the support box limits the position of the linkage shaft. The rotation of bevel gear one drives bevel gear two to rotate, the rotation of bevel gear two drives the linkage shaft to rotate, and the rotation of the linkage shaft drives the rotating disk to rotate, thereby realizing the linkage of the same drive source in two directions.

[0012] As a further description of the above technical solution:

[0013] The stirring mechanism includes a cavity, the bottom of which is fixedly connected to the top of the base box. Two stirring rods are rotatably connected to the inner wall of the cavity, and multiple stirring blades are fixedly connected to the outside of the stirring rods.

[0014] Furthermore, the bottom box provides support for the cavity, making the overall structure more rational. The cavity also fixes the rotation position of the two stirring rods. The rotation of the stirring rods drives multiple stirring blades to rotate, thereby achieving repeated stirring of the feed.

[0015] As a further description of the above technical solution:

[0016] The measurement control mechanism includes a fixed box, the outside of which is fixedly connected to the inner wall of the cavity, a sliding box is slidably connected to the inner wall of the fixed box, and a movable box is slidably connected to the inner wall of the sliding box.

[0017] Furthermore, the cavity has the function of fixing the position of the fixed box to the outside, the sliding box can slide on the inner wall of the fixed box to make the sliding box retract, and the moving box can slide on the inner wall of the sliding box to make the moving box retract. The three interact to achieve precise control of the amount of material fed.

[0018] As a further description of the above technical solution:

[0019] The driving mechanism includes a positioning box, which is fixedly connected to the outside of the cavity. A second motor is installed on the inner wall of the positioning box, and a drive gear is fixedly connected to the drive end of the second motor.

[0020] Furthermore, the cavity serves to fix the position of the positioning box, and the positioning box serves to fix the installation position of the second motor. When the second motor is started, the rotation of the drive end of the second motor can drive the drive gear to rotate, thereby enabling the transmission and realization of the driving force.

[0021] As a further description of the above technical solution:

[0022] The other end of the driving gear is rotatably connected to the outside of the stirring rod, and a driven gear is fixedly connected to the outside of the other stirring rod. The driving gear and the driven gear are meshed together.

[0023] Furthermore, the rotation of the drive gear drives the stirring rod to rotate, which in turn drives the driven gear to rotate, and the rotation of the driven gear drives another stirring rod to rotate, thus providing driving force for the dual-shaft stirring structure.

[0024] As a further description of the above technical solution:

[0025] The movable box is fixedly connected to a traction shaft on the outside, and a hand lever is fixedly connected to the top of the movable box. The fixed box is rotatably connected to a winding shaft, and two traction ropes are fixedly connected to the outside of the winding shaft. The other ends of the two traction ropes are fixedly connected to the outside of the traction shaft.

[0026] Furthermore, the positional change of the traction shaft causes the moving box to change position. Manually moving the hand lever can also cause the moving box to change position, allowing it to reset and prepare for the next control operation. The rotation of the winding shaft causes the traction rope to retract, and the shortening of the traction rope can cause the traction shaft to change position, thereby controlling the sliding of the moving box to control the size of the top discharge port and the amount of material discharged.

[0027] As a further description of the above technical solution:

[0028] A motor is installed on the outside of the cavity, and the drive end of the motor is fixedly connected to the outside of the take-up shaft.

[0029] Furthermore, the cavity serves as a mounting position for motor one. When motor one is started, the rotation of the drive end of motor one drives the take-up shaft to rotate, thereby realizing the take-up function of the take-up shaft.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the movable rod can rotate around the center of the rotating disk, which in turn drives the connecting rod to change position. The position change of the other end of the connecting rod drives the movable ball to change position, thereby causing the screen plate to shake. This allows the stirred feed to be screened, effectively removing impurities, preventing harmful substances from mixing into the feed, protecting animal health, and ensuring uniform feed particle size.

[0032] 2. In this utility model, the traction shaft is traction-slid, which causes the sliding box to slide, discharging part of the feed. The sliding box pushes the sliding box to slide against the inner wall of the fixed box, gradually increasing the amount of feed. Controlling the amount of feed can ensure that the feed is mixed evenly, avoiding uneven mixing due to differences in the amount of material, which would affect the animal's nutrient intake. It can also prevent excessive feed from causing waste. Attached Figure Description

Detailed Implementation

[0041] 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.

[0042] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a dual-shaft paddle mixer for feed mixing, comprising a base box 6, with a screening mechanism 1 installed on the inner wall of the base box 6. The screening mechanism 1 is used to screen the mixed feed, allowing the mixing effect of the feed to be detected and enabling the feed to be consumed by different types of organisms at a more suitable size. A support box 5 is fixedly connected to the outside of the base box 6, used to fix the position of the internal linkage component 107. A mixing mechanism 2 is fixedly connected to the top of the base box 6. The mixing mechanism 2 adopts dual-shaft mixing, making the mixing of feed more uniform. A drive mechanism 4 is installed on the outside of the mixing mechanism 2, used to provide driving force to the mixing mechanism 2. A quantity control mechanism 3 is installed on the top of the mixing mechanism 2, used to control the amount of feed being mixed.

[0043] Feed enters through the inlet. The mixing mechanism 2, driven by the drive mechanism 4, rotates the dual-shaft paddles to mix the feed evenly. The feed control mechanism 3 controls the feed amount according to the set parameters. The mixed feed is further screened by the screening mechanism 1 to ensure that the feed particle size is suitable for different organisms. Throughout the process, the support box 5 stabilizes the position of each component.

[0044] The screening mechanism 1 includes a feeding plate 101, which is fixedly connected to the inner wall of the base box 6. The feeding plate 101 is used to limit the feeding diameter, thus standardizing the screening range. A screen plate 102 is rotatably connected to the inner wall of the base box 6. A movable ball 103 is rotatably connected to the bottom of the screen plate 102. The positional change of the movable ball 103 causes the screen plate 102 to sway. A connecting rod 104 is rotatably connected to the outside of the movable ball 103. The positional change of the connecting rod 104 causes the positional change of the movable ball 103. A linkage assembly 107 is installed on the inner wall of the support box 5. The drive of the linkage assembly 107 drives the rotating disk 105 to rotate. The rotating disk 105 is fixedly connected to the outside of the linkage assembly 107. The drive of the linkage assembly 107 drives the rotating disk 105 to rotate. A movable rod 106 is fixedly connected to the bottom of the rotating disk 105. The rotating disk 105 drives the movable rod 106 to rotate around the center of the rotating disk 105. The movable rod 106 is externally movably connected to the inner wall of the connecting rod 104, and the movable rod 106 pulls one end of the connecting rod 104 to change position.

[0045] The linkage component 107 drives the rotating disk 105 to rotate, which in turn drives the movable rod 106 to rotate around its center. The movable rod 106 pulls one end of the connecting rod 104, causing the position of the connecting rod 104 to change, which in turn drives the position of the movable ball 103 to change. The change in the position of the movable ball 103 then pulls the screen plate 102 to shake, so that the screening mechanism 1 can screen the feed in a standardized manner within the screening range and the screen plate 102 can shake.

[0046] The linkage assembly 107 includes a first bevel gear 1071. A linkage shaft 1072 is rotatably connected to the inner wall of the support box 5, and the support box 5 limits the position of the linkage shaft 1072. A second bevel gear 1073 is fixedly connected to the top of the linkage shaft 1072, and the rotation of the second bevel gear 1073 drives the linkage shaft 1072 to rotate. The second bevel gear 1073 is externally meshed with the first bevel gear 1071, and the rotation of the first bevel gear 1071 drives the second bevel gear 1073 to rotate. The bottom of the linkage shaft 1072 is fixedly connected to the top of the rotating disk 105, and the rotation of the linkage shaft 1072 drives the rotating disk 105 to rotate.

[0047] The rotation of bevel gear 1071 in the linkage assembly 107 drives bevel gear 1073 to rotate through meshing. Bevel gear 1073 causes linkage shaft 1072 to rotate, and linkage shaft 1072 drives rotating disk 105 to rotate, thus realizing the functions of power transmission and rotation.

[0048] Reference Figure 3 The mixing mechanism 2 includes a cavity 201, the bottom of which is fixedly connected to the top of a base box 6. The base box 6 provides support for the cavity 201, making the overall structure more rational. Two mixing rods 202 are rotatably connected to the inner wall of the cavity 201, and the cavity 201 fixes the rotational position of the two mixing rods 202. Multiple mixing blades 203 are fixedly connected to the outside of the mixing rods 202. The rotation of the mixing rods 202 drives the multiple mixing blades 203 to rotate, thereby achieving repeated mixing of the feed.

[0049] In the mixing mechanism 2, the bottom of the cavity 201 is fixed to the top of the bottom box 6 for support. The mixing rod 202, which is rotatably connected to the inner wall of the cavity 201, is connected to multiple mixing blades 203. The rotation of the mixing rod 202 drives the mixing blades 203 to rotate, thereby realizing repeated mixing of the feed.

[0050] The drive mechanism 4 includes a positioning box, which is fixedly connected to the outside of the cavity 201, and the cavity 201 serves to fix the position of the positioning box. A second motor 401 is installed on the inner wall of the positioning box. A drive gear 402 is fixedly connected to the drive end of the second motor 401. Starting the second motor 401 causes the drive gear 402 to rotate. The other end of the drive gear 402 is rotatably connected to the outside of the stirring rod 202, and the rotation of the drive gear 402 causes the stirring rod 202 to rotate. A driven gear 403 is fixedly connected to the outside of another stirring rod 202, and the rotation of the driven gear 403 causes the other stirring rod 202 to rotate. The drive gear 402 and the driven gear 403 are meshed together externally, and the rotation of the drive gear 402 causes the driven gear 403 to rotate.

[0051] The motor 401 of the drive mechanism 4 drives the drive gear 402 to rotate. The drive gear 402 meshes with and drives the driven gear 403 to rotate. The drive and driven gears 403 respectively drive the two stirring rods 202 to rotate, thereby achieving the mixing and stirring of the feed.

[0052] Reference Figure 2 and Figure 6 The control mechanism 3 includes a fixed box 302, which is externally fixedly connected to the inner wall of the cavity 201, and the cavity 201 has a fixed position function for the fixed box 302. A sliding box 303 is slidably connected to the inner wall of the fixed box 302, and the sliding box 303 can retract by sliding on the inner wall of the fixed box 302. A movable box 304 is slidably connected to the inner wall of the sliding box 303, and the movable box 304 can retract by sliding on the inner wall of the sliding box 303. A traction shaft 307 is externally fixedly connected to the movable box 304, and the position change of the traction shaft 307 causes the movable box 304 to change position.

[0053] In the control mechanism 3, the movable box 304 slides on the inner wall of the sliding box 303 under the drive of the traction shaft 307, and the sliding box 303 slides on the inner wall of the fixed box 302. The position of the movable box 304 is changed by the relative sliding of each component, thereby achieving the purpose of control.

[0054] A hand lever 305 is fixedly connected to the top of the movable box 304. Manually moving the hand lever 305 changes the position of the movable box 304, allowing it to reset and prepare for the next control operation. A winding shaft 306 is rotatably connected to the outside of the fixed box 302. Two traction ropes 308 are fixedly connected to the outside of the winding shaft 306. Rotation of the winding shaft 306 causes the traction ropes 308 to retract. The other ends of the two traction ropes 308 are fixedly connected to the outside of the traction shaft 307. Shortening the traction ropes 308 causes the traction shaft 307 to change position. A motor 301 is installed outside the cavity 201. The drive end of the motor 301 is fixedly connected to the outside of the winding shaft 306. Starting the motor 301 causes the drive end of the motor 301 to rotate, thereby realizing the winding function of the winding shaft 306.

[0055] When the control mechanism 3 is working, the motor 301 drives the winding shaft 306 to rotate. Through the traction rope 308 and the traction shaft 307, after the moving box 304 is manually reset by the hand lever, the position of the moving box 304 and the traction shaft 307 can be changed, thus achieving the control operation.

[0056] Working principle: The feed to be mixed is fed into the cavity 201 through the slot at the top, according to the type. The feed falls on the top of the measuring mechanism 3. At this time, the feeding amount needs to be controlled according to the mixing effect. The motor 301 is started. The rotation of the drive end of the motor 301 drives the winding shaft 306 to rotate. The rotation of the winding shaft 306 can wind up the traction rope 308, thereby shortening the traction rope 308 and pulling the traction shaft 307 to slide. The sliding of the traction shaft 307 drives the moving box 304 to slide, discharging part of the feed. The sliding of the moving box 304 pushes the sliding box 303 to slide against the inner wall of the fixed box 302, gradually increasing the feeding amount. Controlling the feeding amount can ensure that the feed is mixed evenly, avoiding uneven mixing due to differences in the amount of material, which would affect the animal's nutrient intake. It can also prevent waste caused by excessive feeding or insufficient feeding that cannot meet the needs, ensuring accurate, stable and efficient feed supply.

[0057] After feeding, the second motor 401 is started. The rotation of the drive end of the second motor 401 can drive the drive gear 402 to rotate. The rotation of the drive gear 402 drives the driven gear 403 to rotate. The rotation of the drive gear 402 and the driven gear 403 can drive the two stirring rods 202 to rotate. The stirring rods 202 drive multiple stirring blades 203 to rotate, thereby mixing and stirring the feed.

[0058] The rotation of one of the stirring rods 202 drives the first bevel gear 1071 to rotate, which in turn drives the second bevel gear 1073 to rotate. The rotation of the second bevel gear 1073 drives the linkage shaft 1072 to rotate, which in turn drives the rotating disk 105 to rotate. This causes the movable rod 106 to rotate around the center of the rotating disk 105, which in turn drives the connecting rod 104 to change position. The position change at the other end of the connecting rod 104 drives the movable ball 103 to change position, which in turn causes the screen plate 102 to shake. This allows the stirred feed to be screened, effectively removing impurities, preventing harmful substances from mixing into the feed, ensuring animal health, ensuring uniform feed particle size, making feeding smoother for animals, increasing feed intake, promoting digestibility, and allowing animals to better absorb nutrients, thereby improving production performance.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
