Description

Technical Field

[0001] The present invention relates to the technical field of feed mixing, and particularly relates to a feed stirring device for preventing feed from adhering to the body wall. Background Art

[0002] The double-cone mixer is a new type, efficient, and fine container-rotating and stirring-type mixing machine, mainly used for the uniform mixing of various powdery and granular materials, with a high degree of mixing, and is applicable to industries such as magnetic powder, ceramics, chemical engineering, pharmaceuticals, and feeds.

[0003] The working process of the double-cone mixer is as follows: several materials to be mixed are put into the double cone through vacuum conveying or manual feeding. The electric motor drives the double-cone tank body to rotate through a speed reducer. Under the action of gravity and centrifugal force, the rotating double-cone cylinder causes the materials in the cylinder to produce disordered tumbling and mixing. During the rotation process, the materials continuously tumble and spread, and finally achieve the effect of uniform mixing, realizing rapid mixing in the cylinder. After mixing is completed, the materials are discharged through the discharge port by relying on their own weight.

[0004] At present, when the double-cone type feed mixer on the market is in use, affected by factors such as the viscosity of the feed, relying solely on the tumbling of the double-cone cylinder for work, the mixing effect is not ideal, and during the discharging process, there is often a situation where the feed adheres to the inner wall of the double-cone cylinder and is difficult to discharge. Summary of the Invention

[0005] In view of the above situation, to overcome the defects of the prior art, the present invention provides a feed stirring device for preventing feed from adhering to the body wall to solve the above problems.

A crankshaft is arranged inside the flipping cylinder. Support rods are arranged on both sides of the crankshaft. The support rods are rotatably connected to the flipping cylinder through penetration. One end of the two support rods passing through the flipping cylinder is fixedly connected to the mounting frame.

Both the first stirring blade and the second stirring blade are spiral ribbon type stirring blades. Two rotation driving mechanisms are arranged on the crankshaft. The first stirring blade and the second stirring blade are respectively driven and matched with the two rotation driving mechanisms. When the flipping cylinder flips, the crankshaft rotates relative to the flipping cylinder, and the two rotation driving mechanisms respectively drive the first stirring blade and the second stirring blade to rotate. While the flipping of the flipping cylinder causes the materials to tumble and mix, the first stirring blade and the second stirring blade perform stirring-type mixing on the materials in the cylinder.

Detailed implementation manners

[0028] Next, reference will be made to Figures 1 to 7 to describe each embodiment of the present invention in detail. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0029] A feed stirring device for preventing adhesion to the body wall, as Figure 1 and Figure 2 shown, includes a mounting frame 1 and a turning cylinder. The turning cylinder includes a cylinder body 13. Feed heads 14 and discharge heads 15 are detachably provided at both ends of the cylinder body 13. In this embodiment, the feed heads 14 and the discharge heads 15 are connected to both ends of the cylinder body 13 by bolts. A crankshaft 3 is provided inside the turning cylinder. Support rods 2 are provided on both sides of the crankshaft 3. The support rods 2 are rotatably connected to the turning cylinder through penetration. One end of each of the two support rods 2 passing through the turning cylinder is fixedly connected to the mounting frame 1; it also includes a transmission pipe 21 fixed to the cylinder body 13. The transmission pipe 21 is coaxially sleeved on the support rod 2. A turning device is installed on the mounting frame 1. The turning device is drivingly connected to the transmission pipe 21. The turning device includes a chain 23, a chain gear 24 and a servo motor (not shown), and the servo motor can rotate forward and backward. The chain gear 24 is coaxially fixedly connected to the transmission pipe 21; when the servo motor drives the chain gear 24 to rotate, the turning cylinder rotates around the support rod 2 as the axis, realizing the turning and mixing function of the turning cylinder.

[0030] As Figure 2 、 Figure 3 and Figure 5As shown in the figure, on one side of the crankshaft 3 near the feeding end and the discharging end of the tipping barrel, a first stirring blade 5 and a second stirring blade 6 are respectively provided. Both the first stirring blade 5 and the second stirring blade 6 are spiral ribbon stirring blades. There are two rotary drive mechanisms on the crankshaft 3. The first stirring blade 5 and the second stirring blade 6 are respectively drivingly engaged with the two rotary drive mechanisms. The rotary drive mechanism includes a linkage rod 9, a lead screw 10 and a sleeve 11. One end of the lead screw 10 is inserted into the interior of the sleeve 11 and can slide within the sleeve 11. The other end of the lead screw 10 is hinged to one end of the linkage rod 9. The other end of the linkage rod 9 is rotatably connected to the crankshaft 3. Ball bearings 22 are provided on the inner wall of the sleeve 11. The ball bearings 22 are in sliding fit with the spiral groove of the lead screw 10. While the tipping barrel is being tipped for mixing, through the cooperative setting of the crankshaft 3, the linkage rod 9, the lead screw 10 and the sleeve 11, the lead screw 10 repeatedly inserts into or withdraws from the sleeve 11. Coupled with the setting of the ball bearings 22, the sleeve 11 is rotated, thereby realizing the rotation of the first stirring blade 5 and the second stirring blade 6, so as to stir and mix the materials in the tipping barrel.

[0031] As Figure 2 , Figure 3 , Figures 5 to 7 shown, a positioning frame 12 is provided on one of the sleeves 11. The positioning frame 12 is rotatably connected to the inner wall of the cylinder body 13. It also includes a mounting shell 30. The mounting shell 30 is located outside the crankshaft 3. The mounting shell 30 serves as an isolation function. Both the support rod 2 and the sleeve 11 are rotatably connected to the mounting shell 30. The lead screw 10 near the feeding head 14 is a reciprocating lead screw, that is, during the telescopic process of this lead screw 10, the corresponding sleeve 11 can only rotate in one direction, that is, the first stirring blade 5 can only rotate in one direction, while the second stirring blade 6 can rotate in both directions, so that during the use of this device, there are two stirring and mixing states. The materials in area a and area b flow in the same direction for mixing, and the materials in area a and area b flow in opposite directions for counter-flushing mixing.

[0032] As Figure 2 and Figure 4As shown, a conical flow guide cylinder 4 is slidably connected inside the turning cylinder. In this embodiment, key blocks are provided on the conical flow guide cylinder 4, and key grooves are provided on the inner wall of the cylinder body 13. The key blocks and the key grooves are slidably connected, and the key blocks and the key grooves are not shown, that is, the conical flow guide cylinder 4 can only slide inside the turning cylinder; the conical flow guide cylinder 4 is located between the discharge end of the turning cylinder and the second stirring blade 6. An expansion ring is installed between the discharge end of the conical flow guide cylinder 4 and the discharge end of the turning cylinder. A filter screen 7 is installed on the conical flow guide cylinder 4; a contact block 8 is provided on the conical flow guide cylinder 4, and the second stirring blade 6 is in driving cooperation with the contact block 8; in the initial state, the side wall of the conical flow guide cylinder 4 fits against the inner wall of the discharge head 15, that is, the liquid inside the turning cylinder cannot be discharged from the filter screen 7 at this time. When the expansion ring expands, it pushes against the conical flow guide cylinder 4 away from the discharge head 15, and a liquid discharge cavity 26 is formed between the conical flow guide cylinder 4 and the inner wall of the discharge head 15. At this time, the liquid inside the turning cylinder flows into the liquid discharge cavity 26 through the filter screen 7.

[0033] An outlet cylinder 17 is provided at the outlet end of the discharge head 15. A discharge valve 18 is provided at the bottom of the outlet cylinder 17, and a liquid outlet hole 19 is opened on the inner bottom wall of the outlet cylinder 17.

[0034] As Figure 2 and Figure 4 shown, the expansion ring includes a fixed ring 20. The fixed ring 20 is fixed on the inner bottom wall of the outlet cylinder 17. A guide groove 27 is opened on the side of the fixed ring 20 close to the conical flow guide cylinder 4. A telescopic ring 28 is fixedly connected to the outlet of the conical flow guide cylinder 4. The other end of the telescopic ring 28 is inserted into the guide groove 27 and can slide in the guide groove 27. A spring 29 is installed between the inner bottom wall of the guide groove 27 and the telescopic ring 28. When the fixed ring 20 is inflated, the telescopic ring 28 extends, and the spring 29 is stretched and stores energy, thereby pushing against the conical flow guide cylinder 4 away from the discharge head 15.

[0035] As Figures 1 to 3 shown, it further includes an inflation device. In this embodiment, the inflation device is an air pump. The inflation device is installed on either the cylinder body 13 or the discharge head 15. An air delivery pipe 16 is provided on the fixed ring 20. The air delivery pipe 16 is in internal communication with the guide groove 27. The other end of the air delivery pipe 16 is in fluid communication with the output end of the inflation device. An exhaust valve for exhausting gas is also provided on the fixed ring 20 and is not shown. After the device is used, the gas in the guide groove 27 can be discharged through the exhaust valve, and the spring 29 pulls the telescopic ring 28 back.

[0036] The outer edges of the first stirring blade 5 and the second stirring blade 6 are both in contact with the inner wall of the cylinder body 13. During the rotation of the first stirring blade 5 and the second stirring blade 6, the materials on the inner wall of the cylinder body 13 can be scraped off, preventing a large amount of materials from adhering to the inner wall of the cylinder body 13.

[0037] When the device is in use, first put water and dry feed into the device through the feed valve 25 to soak the dry feed. After the dry feed is soaked, start the inflation device to inflate the guide groove 27, and the telescopic ring 28 extends, thereby pushing the conical guide cylinder 4 away from the discharge head 15, so that a drainage cavity 26 is formed between the inner wall of the conical guide cylinder 4 and the discharge head 15. Then, the water in the cylinder body 13 passes through the filter screen 7, the drainage cavity 26, and the discharge cylinder 17 in sequence, and finally is discharged from the device through the liquid discharge hole 19 to realize the dehydration of the feed.

[0038] Add ingredients (such as proteins, vitamins, and flavoring agents, etc.) into the device through the feed valve 25. Then, the servo motor drives the chain gear 24 to rotate, so that the cylinder body 13 rotates around the support rod 2 as the axis to realize the function of flipping and mixing; while the cylinder body 13 is flipped for mixing, through the combined setting of the crankshaft 3, the connecting rod 9, the lead screw 10, and the sleeve 11, the lead screw 10 makes a reciprocating telescopic motion, and then with the setting of the ball 22, the sleeve 11 rotates, thereby realizing the rotation of the first stirring blade 5 and the second stirring blade 6, so as to stir and mix the materials in the cylinder body 13, improving the mixing efficiency and the uniformity of the mixing of the materials.

[0039] It should be noted that the lead screw 10 close to the feed head 14 is a reciprocating lead screw, that is, during the telescopic process of the two lead screws 10, the first stirring blade 5 can only rotate in one direction, while the second stirring blade 6 can rotate in both directions, so that during the flipping process of the cylinder body 13, the device has two stirring and mixing methods, the materials in area a and area b flow in the same direction for mixing, and the materials in area a and area b flow in opposite directions for countercurrent mixing, further improving the mixing uniformity.

[0040] After the mixing of the device is completed, place the discharge head 15 and the discharge valve 18 below, and place the food trough below the discharge valve 18. Open the discharge valve 18 and make the servo motor rotate intermittently in small amplitude in both forward and reverse directions, and the cylinder body 13 swings in small amplitude. At the same time, the first stirring blade 5 and the second stirring blade 6 rotate, which can reduce the possibility of blockage of the discharge valve 18.

[0041] It is worth noting that as the materials in the cylinder body 13 are continuously discharged, the weight of the materials borne by the conical guide cylinder 4 continuously decreases. Affected by the air pressure in the guide groove 27, the telescopic ring 28 extends and pushes the conical guide cylinder 4 to move closer to the second stirring blade 6. After the conical guide cylinder 4 moves to the set position, when the second stirring blade 6 rotates in small amplitude, it will push against the contact block 8. It should be noted that at this time, the second stirring blade 6 rotates in small amplitude reciprocally, so that the conical guide cylinder 4 shakes up and down, preventing a large amount of materials from remaining on the conical guide cylinder 4 and being unable to be discharged due to factors such as friction, thereby causing waste of resources.

[0042] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0043] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
