At the same time, the flip mechanism drives the rotating rod to rotate.

The rotating rod then transports these larger particles to the device installation column.

[0016] S3: The materials are ground by the grinding device and then enter the mixing tank.

During this process, all the materials can come into contact with the material diverter mechanism, so that the material diverter mechanism can clean up the larger particles of pig feed raw materials in all the materials.

[0017] Beneficial effects:

[0018] (1) In the present invention, pig feed raw materials and additives are placed in the stirring tank, and then the driving motor is started. The driving motor drives the rotation of the rotating column, and the rotating column drives the rotating rod to make a circumferential motion around the rotating column. At the same time, the turning mechanism drives the rotating rod to rotate. The rotating rod drives the material-dividing mechanism to screen out the pig feed raw materials with larger particles in the stirring tank and transport them to the rotating rod. The rotating rod transports these larger particles to the device installation column and grinds them through the grinding device. Then, they enter the stirring tank and stir and flip the materials in the stirring tank through the stirring plate, so that the materials are turbulent and mixed. In this process, all materials can contact the material-dividing mechanism, so that the material-dividing mechanism can clean up the larger particles of pig feed raw materials in all materials, which can effectively promote the fusion of pig feed raw materials and additives and enhance the effectiveness of pig feed.

[0019] (2) In the present invention, the moment the material filter plate just comes out of the material, the material filter plates on both sides of the deflection rod will deflect due to uneven force. Under the action of the shaking spring, the deflection rod and the lateral extension rod will produce reciprocating shaking, thereby causing the material filter plate to shake, making it easier for larger particles of pig feed raw materials to move on the material filter plate, and helping to screen larger particles in the pig feed raw materials.

[0020] (3) The grinding rollers on the grinding table of the present invention rotate due to the squeezing of the pig feed raw materials. The protrusions on the grinding rollers further squeeze the larger particles of the pig feed raw materials, thereby improving the grinding effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] First embodiment:

[0031] like Figure 1 and Figure 2As shown, the present invention provides a pig feed mixing and stirring equipment, including a mixing tank 1 with legs fixedly installed at the lower end, the upper end fixed frame of the mixing tank 1 is provided with a driving fixed frame 11, and a device mounting column 12 is fixedly installed in the middle position of the mixing tank 1. The device mounting column 12 is hollow, and a rotating column 2 is rotatably installed in the middle position of the driving fixed frame 11. The rotating column 2 passes through the driving fixed frame 11 and extends into the upper end of the device mounting column 12. A driving motor is fixedly installed on the upper end of the driving fixed frame 11, and the output shaft of the driving motor is fixedly connected to the rotating column 2. The rotating rod 3 is rotatably installed on the rotating column 2. The lower end of the moving column 2, and the rotating rod 3 is evenly distributed along the circumference of the rotating column 2. The rotating rod 3 is hollow, and the material-dispensing mechanism 4 is installed on the rotating rod 3 and communicated with the inside of the rotating rod 3. The flipping mechanism 5 is installed between the device mounting column 12 and the rotating column 2, and is used to drive the rotation of the rotating rod 3. The grinding device 6 is arranged inside the device mounting column 12. The rotating column 2 is fixedly connected to a downwardly extending synchronization rod 21, and a synchronization ring 22 is fixedly installed at the lower end of the synchronization rod 21. The stirring plate 7 is fixedly installed on the side of the synchronization ring 22 in an inclined state, and there are multiple stirring plates 7 evenly distributed circumferentially.

[0032] When preparing pig feed, the pig feed raw materials and additives are put into the mixing tank 1, and then the driving motor is started. The driving motor drives the rotation of the rotating column 2, and the rotating column 2 drives the rotating rod 3 to make a circumferential motion around the rotating column 2. At the same time, the turning mechanism 5 drives the rotating rod 3 to rotate. The rotating rod 3 drives the material-dividing mechanism 4 to screen out the pig feed raw materials with larger particles in the mixing tank 1 and transport them to the rotating rod 3. The rotating rod 3 transports these larger particles to the device mounting column 12, and is ground by the grinding device 6. Then, it enters the mixing tank 1 and stirs and flips the materials in the mixing tank 1 through the stirring plate 7, so that the materials are turbulent and mixed. In this process, all materials can contact the material-dividing mechanism 4, so that the material-dividing mechanism 4 can clean up the larger particles of pig feed raw materials in all materials.

[0033] Second embodiment:

[0034] like Figure 2 and Figure 3 As shown, the flip mechanism 5 includes a flip main bevel gear 51 and a flip secondary bevel gear 52. The flip main bevel gear 51 is fixedly mounted on the upper end of the device mounting column 12, and the flip secondary bevel gear 52 is fixedly connected to the rotating rod 3. The flip main bevel gear 51 and the flip secondary bevel gear 52 are engaged with each other.

[0035] When the rotating column 2 drives the rotating rod 3 to perform circumferential motion, the flip secondary bevel gear 52 and the flip primary bevel gear 51 engage with each other, so that the flip secondary bevel gear 52 drives the rotating rod 3 to rotate.

[0036] Third embodiment:

[0037] like Figure 2 、 Figure 3 and Figure 4 As shown, the material-discharging mechanism 4 includes a lateral extending rod 41, a deflection rod 42, a shaking mechanism 43 and a material-discharging filter plate 44. The lateral extending rod 41 is fixedly mounted on the side of the rotating rod 3. The deflection rod 42 is coaxially mounted with the lateral extending rod 41 through the shaking mechanism 43. The material-discharging filter plate 44 is V-shaped and fixedly connected to the deflection rod 42. The deflection rod 42 is communicated with the lateral extending rod 41. The deflection rod 42 is communicated with the rotating rod 3. A material feed trough 421 is provided on the deflection rod 42 corresponding to the material-discharging filter plate 44.

[0038] like Figure 4 As shown, a material blocking plate 441 is fixedly connected to one side of the material filter plate 44 close to the rotating rod 3 .

[0039] In the process of screening larger pig feed raw materials by the material-dividing mechanism 4, the rotating rod 3 will drive the rotation of the lateral extension rod 41, and the lateral extension rod 41 will drive the rotation of the deflection rod 42. The material-dividing filter plate 44 on the deflection rod 42 will scoop up the material and screen out the larger granular pig feed raw materials and enter the deflection rod 42 through the feed trough 421, and enter the lateral extension rod 41 through the deflection rod 42. Setting the material-dividing filter plate 44 into a V-shape can effectively screen out the pig feed raw materials and enter the deflection rod 42 through the feed trough 421. At the same time, the shaking mechanism 43 can make the material-dividing filter plate 44 self-shaking, which facilitates the movement of larger granular pig feed raw materials on the material-dividing filter plate 44. At the same time, the material blocking plate 441 can prevent the material from leaking from the side of the material-dividing filter plate 44.

[0040] Fourth embodiment:

[0041] like Figure 4 and Figure 5As shown, the shaking mechanism 43 includes a fixed sleeve 431 and a rotating sleeve 432, the fixed sleeve 431 is fixedly connected to the lateral extension rod 41, the rotating sleeve 432 is rotatably connected to the deflection rod 42, the fixed sleeve 431 is rotatably connected to the rotating sleeve 432, a rebound groove 4311 is provided on the fixed sleeve 431, baffles 4312 are fixedly connected at the upper and lower positions of the middle position of the rebound groove 4311, a spring guide ring 4313 is installed at the middle position of the baffle 4312, a shaking slider 4314 is slidably connected to the left and right positions of the rebound groove 4311, the shaking slider 4314 is fixedly connected to the rotating sleeve 432, a shaking spring 4315 is sleeved on the spring guide ring 4313, and the two ends of the shaking spring 4315 are respectively fixedly connected to the baffle 4312 and the shaking slider 4314.

[0042] When the shaking mechanism 43 drives the material-diverting filter plate 44 to shake, at the moment when the material-diverting filter plate 44 just comes out of the material, the material-diverting filter plates 44 on both sides of the deflection rod 42 will deflect due to uneven force. Under the action of the shaking spring 4315, reciprocating shaking will occur between the deflection rod 42 and the lateral extension rod 41, thereby causing the material-diverting filter plate 44 to shake.

[0043] Fifth embodiment:

[0044] like Figure 3 As shown, a discharge rack 23 is fixedly connected to the inner side of the rotating column 2 corresponding to the rotating rod 3 , and a discharge screw 24 is fixedly connected to the discharge rack 23 corresponding to the rotating rod 3 , and the discharge screw 24 extends into the rotating rod 3 .

[0045] After the material enters the rotating rod 3 , as the rotating rod 3 rotates, the discharging screw 24 will gradually transport the material to the device installation column 12 .

[0046] Sixth embodiment:

[0047] like Figure 3 and Figure 6As shown, a grinding device 6 is arranged between the discharging rack 23 and the device mounting column 12, and the grinding device 6 includes a grinding table 61, a grinding sleeve 62 and a discharging table 63. The grinding table 61 is fixedly mounted on the lower end of all the discharging racks 23, and the grinding table 61 is in a truncated cone shape. The grinding sleeve 62 is sleeved on the outer side of the discharging table 63 and is fixedly connected to the device mounting column 12. The middle of the grinding sleeve 62 is a truncated cone-shaped cavity, and the distance between the inner side wall of the grinding sleeve 62 and the side wall of the grinding table 61 decreases from top to bottom. A discharging table 63 is arranged at the lower end of the grinding table 61, and the discharging table 63 is also in a truncated cone shape, and the discharging table 63 is fixedly connected to the side wall of the device mounting column 12. The side wall of the device mounting column 12 is circumferentially provided with a plurality of discharging troughs 121 corresponding to the discharging table 63.

[0048] When the larger particles of pig feed raw materials enter the device mounting column 12, they will first fall into the position between the grinding sleeve 62 and the grinding table 61. As the distance between the grinding table 61 and the grinding sleeve 62 gradually decreases from top to bottom, the larger particles of pig feed raw materials will be crushed due to compression and fall onto the discharge table 63 through the gap between the grinding table 61 and the grinding sleeve 62, and finally enter the mixing tank 1 from the discharge chute 121.

[0049] like Figure 6 As shown, a grinding groove 611 is opened on the side wall of the grinding table 61, and a grinding roller 612 is rotatably connected in the grinding groove 611. The outer wall of the grinding roller 612 is processed with a protrusion along its axial direction, and there are multiple protrusions on the grinding roller 612 evenly arranged along the circumference of the grinding roller 612.

[0050] The grinding roller 612 on the grinding table 61 will rotate due to the squeezing of the pig feed raw materials. The protrusions on the grinding roller 612 will further squeeze the larger particles of the pig feed raw materials, thereby improving the grinding effect.

[0051] The present invention also provides a stirring method of a pig feed mixing and stirring device, comprising the following steps:

[0052] S1: Put the pig feed raw materials and additives into the mixing tank 1;

[0053] S2: Start the driving motor, the driving motor drives the rotation of the rotating column 2, the rotating column 2 drives the rotating rod 3 to make a circumferential motion around the rotating column 2, and at the same time the turning mechanism 5 drives the rotating rod 3 to rotate, the rotating rod 3 drives the material-dividing mechanism 4 to screen out the pig feed raw materials with larger particles in the mixing tank 1 and transport them to the rotating rod 3, and the rotating rod 3 then transports these larger particles to the device installation column 12. In this process, the rotating rod 3 drives the rotation of the lateral extension rod 41, and the lateral extension rod 41 drives the rotation of the deflection rod 42, and the material-dividing filter plate 4 on the deflection rod 42 is rotated. 4 will scoop up the material and filter out the larger particles of pig feed raw materials and pass them into the deflection rod 42 through the feed chute 421, and then enter the lateral extension rod 41 through the deflection rod 42. The material filter plate 44 is set in a V shape, which can effectively filter out the pig feed raw materials and pass them into the deflection rod 42 through the feed chute 421. At the same time, the shaking mechanism 43 can make the material filter plate 44 self-shaking, which facilitates the movement of larger particles of pig feed raw materials on the material filter plate 44. At the same time, the material blocking plate 441 can prevent the material from leaking from the side of the material filter plate 44.

[0054] S3: Grind the material through the grinding device 6 and then enter the stirring tank 1. The stirring plate 7 is used to stir and flip the material in the stirring tank 1, so that the material is turbulent and mixed. In this process, all the materials can contact the material digging mechanism 4, so that the material digging mechanism 4 can clean up the larger particles of pig feed raw materials in all the materials. In this process, when the larger particles of pig feed raw materials enter the device mounting column 12, they will first fall into the position between the grinding sleeve 62 and the grinding table 61. As the distance between the grinding table 61 and the grinding sleeve 62 gradually decreases from top to bottom, the larger particles of pig feed raw materials will be crushed due to extrusion, and fall onto the discharge table 63 through the gap between the grinding table 61 and the grinding sleeve 62, and finally enter the stirring tank 1 from the discharge trough 121.
