Description

Technical Field

[0001] The present application relates to the technical field of feed mixing, and in particular to a feed mixer. Background Art

[0002] In animal husbandry, the main demand is for feed, including in veterinary medicine, because feed is generally not a single raw material, it needs to be mixed with multiple raw materials to get the required feed. The commonly used equipment is a feed mixer. The general feed mixer is driven by a motor to rotate the stirring rod (or spiral blade) to mix the various feeds in the feed box evenly, but it also has certain shortcomings:

[0003] First, when mixing, all kinds of raw materials are usually poured into the mixing box at once, and then the motor is started to work. This will cause each raw material to pile up seriously, and it will take longer to mix and stir later, resulting in low efficiency. In addition, a lot of dust will be generated during mixing and stirring, which will also affect the health of the staff;

[0004] Secondly, when mixing and stirring, the stirring rod or spiral blade is used to rotate alone, so it takes a long time to fully mix the various raw materials, and it may not necessarily achieve the required mixing uniformity. At the same time, they are also piled up for stirring. Because they are solid, it is more difficult to mix the upper and lower raw materials, resulting in poor mixing uniformity.

[0005] Finally, during mixing, since the stirring shaft is in a state of continuous working and the raw materials inside are constantly moving, a certain amount of heat will be generated inside the mixing box, and dust will also be generated during the mixing and stirring itself, so there will be certain safety hazards. Summary of the invention

[0012] Furthermore, a rectangular groove is provided at the bottom of the rotating shaft, a rectangular block is fixedly connected to the middle of the top surface of the stirring shaft, and the rectangular block is slidably sleeved in the rectangular groove, and a bellows is fixedly connected between the bottom surface of the rotating shaft and the top surface of the stirring shaft.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] See also Figure 1-Figure 9A feed mixer comprises a body 1, a frame 2 is fixedly installed on the outer ring of the bottom of the body 1, a raw material hopper 3 is evenly fixedly installed on the top of the body 1 in an annular shape, a mixing chamber 101 is opened in the middle of the body 1, a feeding chamber 102 is opened inside the top of the body 1, and a feeding port of the raw material hopper 3 is connected with the feeding chamber 102, and a feeding trough 103 is evenly opened at the bottom edge of the feeding chamber 102 in an annular shape. By setting the feeding chamber 102 for preliminary mixing and feeding, on the one hand, various raw materials that fall intermittently can be mixed in the feeding chamber 102, and on the other hand, by intermittently discharging at the bottom of the raw material hopper 3, the raw materials can fall into the mixing chamber 101 through the feeding chamber 102 and the feeding trough 103. , a space is added for buffering to avoid generating a large amount of dust. A turntable 4 is rotatably installed at the bottom of the mixing chamber 101, and a mixing barrel 5 is fixedly installed on the top of the turntable 4. A main motor 6 is fixedly installed in the middle of the top surface of the body 1, and the output shaft of the main motor 6 is fixedly connected with a rotating shaft 7, and the rotating shaft 7 passes through the top of the body 1 and extends into the mixing chamber 101. A stirring shaft 8 is movably connected to the bottom of the rotating shaft 7, and stirring rods 801 are evenly arranged on the outer ring of the stirring shaft 8. A rotating block 9 is fixedly installed on the outer ring of the rotating shaft 7 on the top wall of the feeding chamber 102, and slots 901 are evenly opened on the rotating block 9. A discharge port 104 is opened on one side of the body 1 at the bottom of the mixing chamber 101, and a blocking block 11 is clamped inside the discharge port 104. The upper half of the feeding chamber 102 is opened in a cone shape, and the opening area where the upper half and the lower half are connected is the smallest. The outer ring of the rotating shaft 7 is located in the lower half of the feeding chamber 102, and a material-shifting piece 12 is fixedly installed, and the feeding trough 103 is just located at the outer end of the material-shifting piece 12. The raw materials falling from the raw material hopper 3 will slide downward along the inner wall of the feeding chamber 102 to the bottom, and then will be pushed to the outer ring by the rotating material-shifting piece 12, thus completing the preliminary mixing and feeding. Moreover, the raw materials coming down from the slot 901 are intermittent, but a certain amount of accumulation can be generated at the bottom of the feeding chamber 102, so that the feeding of the feeding trough 103 can be continuous, and will not affect the feed mixing effect inside the mixing barrel 5 and the stirring shaft 8. The number of slots 901 is the same as the number of raw material hoppers 3, and the area of ​​the slots 901 is larger than the area of ​​the discharge port of the raw material hopper 3. When the rotating block 9 rotates along with the rotating shaft 7, the raw material hopper 3 can be continuously discharged at intervals. Moreover, the larger area of ​​the slots 901 can ensure that the amount of material discharged each time is not too little, and blockage can also be avoided.

[0034] See also Figure 4-Figure 8A forward and reverse motor 10 is fixedly installed at the bottom of the body 1, and the output shaft of the forward and reverse motor 10 is fixedly connected to the central axis of the turntable 4. The mixing drum 5 is set in a cone shape and the top cross-section is smaller than the bottom cross-section. The bottom outer ring of the mixing drum 5 is annular and evenly provided with a discharge port 501. The outer surface of the mixing drum 5 is provided with spiral blades 502, and the inner surface of the mixing drum 5 is evenly provided with fixed rods 503. The inside of the mixing drum 5 is mixed and stirred by the fixed rod 503 in cooperation with the stirring shaft 8. After mixing and stirring to a certain extent, it will be discharged from the discharge port 501 to the outside of the mixing drum 5, and then transported to the top of the mixing drum 5 through the spiral blades 502 for unloading again. This can make the mixing of the raw materials more uniform, and it can also avoid the problem of accumulation and blockage. The mixing chamber 101 is opened in a cone shape, and the inner wall cone generatrix of the mixing chamber 101 is parallel to the outer circle cone generatrix of the mixing barrel 5. The spiral blades 502 fit the inner wall of the mixing chamber 101. Feed can be transported between the mixing chamber 101 and the mixing barrel 5 through the spiral blades 502, thereby achieving a more uniform feed mixing effect.

[0035] See also Figure 4-Figure 10 A rectangular groove 701 is provided at the bottom of the rotating shaft 7, a rectangular block 802 is fixedly connected to the middle of the top surface of the stirring shaft 8, and the rectangular block 802 is slidably sleeved in the rectangular groove 701, and a corrugated tube 13 is fixedly connected between the bottom surface of the rotating shaft 7 and the top surface of the stirring shaft 8. The rectangular groove 701 is sleeved with the rectangular block 802 to achieve a transmission effect, so that the stirring shaft 8 can rotate with the rotating shaft 7 and perform mixing and stirring. At the same time, the stirring shaft 8 must be able to achieve a certain degree of up and down movement, so the depth of the rectangular groove 701 is greater than the length of the rectangular block 802, and the corrugated tube 13 is sleeved on the outside to play a protective role to prevent feed particles from getting stuck inside. The top surface of the turntable 4 is located at the inner circle of the mixing barrel 5 and is convex, and a sleeve groove 401 is provided in the middle of the convexity. The bottom of the stirring shaft 8 is sleeved in the sleeve groove 401. A fixing ring 14 is fixedly installed at the bottom of the sleeve groove 401. The sleeve groove 401 can limit the stirring shaft 8 to a certain extent, so that it can be ensured that the stirring shaft 8 will not swing left and right when it rotates. A protrusion 803 is fixedly installed at the bottom edge of the stirring shaft 8, and the protrusion 803 is always in contact with the top of the fixing ring 14. The height of the fixing ring 14 rises and then falls. In this way, when the stirring shaft 8 drives the protrusion 803 to rotate a circle, the action of rising and falling can be realized, which is transmitted to the stirring shaft 8 to drive the stirring rod 801 to also realize the rising and falling action synchronously. In this way, the reciprocating effect of up and down fluctuations is achieved, which improves the feed mixing effect.

[0036] See also Figure 4-Figure 6A cooling channel 105 is provided in the inner wall of the machine body 1, and a cooling water joint is connected to the outer side of the frame 2 and communicated with the cooling channel 105. The cooling water is circulated in the cooling channel 105 inside the machine body 1 to reduce the temperature, thereby avoiding certain safety hazards caused by excessive temperature inside the mixing chamber 101. A regulating valve 15 is installed inside the discharge end of the raw material hopper 3. The discharge situation at the bottom of the raw material hopper 3 can be controlled by adjusting the regulating valve 15. Because the rotation speed of the rotating shaft 7 cannot be too fast or too slow, it is sometimes necessary to control the discharge situation by controlling the opening size of the discharge port of the raw material hopper 3 through the regulating valve 15.

[0037] Working principle: first, add the feed raw materials to be mixed into separate raw material hoppers 3, adjust the regulating valve 15 to open the discharge ports of different sizes, and then start the main motor 6 to drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it also drives the stirring shaft 8, the rotating block 9 and the material-digging piece 12 to rotate synchronously. When the rotating block 9 rotates, it drives the notch 901 to rotate through the discharge port of the raw material hopper 3 at intervals, so that the raw materials in the raw material hopper 3 can fall into the discharge cavity 102 at intervals, and then slide along the inner wall of the discharge cavity 102 to the bottom, and then the rotation of the material-digging piece 12 will push the raw materials to move to the outer circle and fall from the discharge chute 103;

[0038] Next, the raw materials dropped from the feed chute 103 into the mixing drum 5 are stirred and mixed by the stirring shaft 8, and at the same time, the forward and reverse motors 10 are also started, thereby driving the turntable 4 to rotate. When the turntable 4 rotates, the mixing drum 5 is also driven to rotate synchronously, and the rotation direction is opposite to the rotation direction of the stirring shaft 8. At this time, the raw materials are evenly mixed under the rotation of the stirring rod 801 and the fixed rod 503;

[0039] After that, the feed mixed and stirred to the bottom of the mixing drum 5 will slide down along the protrusions on the top of the rotating disk 4, and together with the centrifugal force during rotation, it will move to the outside of the mixing drum 5 along the discharge port 501. After that, due to the arrangement of the spiral blades 502 on the outside of the mixing drum 5, the mixed feed will move upward along the spiral blades 502 and the inner wall of the mixing chamber 101, so as to be lifted to the top of the mixing drum 5 and then fall down, thus increasing the mixing effect and making the mixing more uniform.

[0040] During the mixing process, the stirring shaft 8 rotates and the boss 803 is driven to rotate continuously. During one rotation of the boss 803, it will rise and then fall along the top surface of the fixed ring 14, thereby driving the stirring shaft 8 to do up and down movement, thereby cooperating with the rectangular block 802 and the fixed rod 503 to achieve a better mixing and stirring effect. After the mixing is completed, the main motor 6 is stopped, the blocking block 11 is opened, and then the forward and reverse motors 10 are started to rotate in the reverse direction, so that the mixed feed is discharged from the bottom of the discharge port 104.
