[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-8A feed-grade crushing and stirring structure includes a body 1, a driving motor 3 is installed on the upper part of the body 1, the output end of the driving motor 3 extends into the crushing chamber 4 inside the body 1 and is driven and connected to a driving shaft 31, a plurality of crushing hammers 6 are installed on the driving shaft 31, and crushing pieces 61 are mounted on the outer sides of the crushing hammers 6 through mounting grooves 13, and the bottom end of the driving shaft 31 is rotatably mounted in the forming screen 7, and a plurality of stirring rollers 8 are driven and connected to the driving shaft 31 through a planetary gear seat 17, and the stirring rollers 8 are in extrusion contact with the upper wall of the forming screen 7;

[0031] Furthermore, a planetary gear seat 17 is installed in the middle of the forming screen 7, and a drive shaft 31 is rotatably installed in the middle of the planetary gear seat 17. One end of the drive shaft 31 passes through the planetary gear seat 17 and the forming screen 7 and is connected to a cutting rod 20. The cutting rod 20 is installed below the forming screen 7. The strip feed discharged from the bottom of the forming screen 7 can be cut by the cutting rod 20, and the feed can be cut into strips to facilitate discharge.

[0032] Furthermore, multiple sets of planetary gears are provided in the middle of the planetary gear seat 17, and the outer side of each set of planetary gears is meshed and connected with a transmission ring 18. The transmission ring 18 is rotatably installed on the outer wall of the planetary gear seat 17 through a bearing, and multiple stirring rollers 8 are rotatably installed on the outer wall of the transmission ring 18. The outer wall of the stirring roller 8 is provided with a crushing bar 81, wherein the stirring roller 8 is in extrusion and friction contact with the upper wall of the forming screen 7.

[0033] Furthermore, a feed port 2 is installed on one side of the upper part of the body 1, and the feed port 2 is connected to a crushing chamber 4 provided on the upper side of the interior of the body 1. A mixing chamber 41 is provided below the crushing chamber 4, and a discharge chamber 42 is provided below the mixing chamber 41. A discharge port 5 is provided at one end of the discharge chamber 42.

[0034] Furthermore, a guide slope 421 is obliquely installed at the bottom of the discharge chamber 42 , and a forming screen 7 is provided above the guide slope 421 .

[0035] Furthermore, a plurality of crushing seats 16 are installed on the inner wall of the crushing chamber 4, and a gap is left between each group of crushing seats 16 to allow the crushing hammer 6 to pass through. A certain gap is left between the crushing hammer 6 and the inner wall of the crushing chamber 4, thereby efficiently crushing the lumps in the feed raw materials.

[0036] Furthermore, limiting blocks 12 are installed at both ends of one side of the crushing piece 61, and a mounting block 11 is installed in the middle. A screw hole is opened in the middle of the mounting block 11, wherein the crushing piece 61 is installed in the mounting groove 13 and the mounting groove 2 14 opened on the outside of the crushing hammer piece 6 through the limiting block 12 and the mounting block 11.

[0037] Furthermore, an adjusting bolt 15 is screwed to one side of the inner portion of the crushing hammer piece 6 , and one end of the adjusting bolt 15 extends into the second mounting groove 14 and is screwed to the mounting block 11 .

[0038] Furthermore, a mounting seat 62 is installed on one side of the crushing hammer 6, and the mounting seat 62 is fixedly mounted on a mounting plate 311 set in the middle of the driving shaft 31 through a fastener 9, wherein a mounting hole 10 is opened on the mounting plate 311 to install the fastener 9.

[0039] Furthermore, a forming screen 7 is fixedly installed in the middle of the mixing chamber 41, and a plurality of sieve holes are opened in the middle of the forming screen 7 to pass the material.

[0040] Furthermore, a driving gear 19 is fixedly mounted on the bottom of the driving shaft 31 . The driving gear 19 is rotatably mounted inside the planetary gear seat 17 and is in driving engagement with a plurality of planetary gears.

[0041] In this embodiment, the feed raw materials are introduced into the crushing chamber 4 inside the body 1 through the feed inlet 2, and the driving motor 3 is operated so that the driving shaft 31 drives multiple groups of crushing hammers 6 to rotate at high speed. During the rotation process, the crushing hammers 6 hit and crush the feed raw materials, and cooperate with the crushing seat 16 to grind the feed raw materials, thereby effectively crushing the lumps in the feed raw materials, and then the crushed feed powder falls on the forming screen 7 at the bottom. Synchronously, under the rotation of the driving shaft 31, the driving shaft 31 cooperates with the driving gear 19 to rotate. The planetary gear seat 17 drives the transmission ring 18 to rotate at a uniform speed, wherein the multiple groups of stirring rods 8 connected to the transmission ring 18 roll and rub against the upper wall of the forming screen 7, and repeatedly crush the feed powder, further improving the crushing and stirring efficiency. At the same time, after repeated stirring and crushing, the material is gradually discharged through the sieve holes in the forming screen 7 under the action of crushing and forms strips. At this time, the driving shaft 31 synchronously rotates the cutting rod 20, and the cutting rod 20 cuts the formed material and discharges the feed to the discharge port 5 through the guide slope 421 in the discharge chamber 42.

[0042] Among them, during actual use, the adjusting bolt 15 provided on the upper part of the crushing hammer 6 can still be adjusted. The adjusting bolt 15 rotates and drives the mounting block 11 connected thereto to move through the threaded rotation, thereby changing the installation position of the crushing piece 61, that is, the gap between the crushing piece 61 and the inner wall of the crushing chamber 4. At the same time, the crushing piece 61 can still be removed by the adjusting bolt 15 to ensure service life and grinding efficiency.

[0043] Among them, it is worth noting that the drive shaft 31 drives the drive gear 19 to rotate, and the drive gear 19 engages and transmits with multiple sets of planetary gears arranged in the planetary gear seat 17. Synchronously, the planetary gears rotate synchronously in the tooth grooves on the inner wall of the transmission ring 18, thereby driving the transmission ring 18 to rotate. The planetary gear box and its internal planetary gears, sun gear and other components are already existing technologies, and their transmission principles will not be elaborated here.

[0044] In the present invention, the driving motor 3 drives multiple groups of crushing hammers 6 to rotate at high speed, and cooperates with the crushing seat 16 to hit and grind the material, wherein the hard blocks in the material are effectively crushed, and the powder falls onto the forming screen 7, and the planetary gear seat 17 is linked to drive multiple groups of stirring rollers 8 to further crush the powder, and the powder is squeezed into the sieve hole, and the synchronously rotating cutting rod 20 cuts the material into strips for discharge. The process can effectively crush and stir the material and improve the quality of the feed.

[0045] At the same time, the position of the crushing piece 61 can be changed by adjusting the adjusting bolt 16 provided on the crushing hammer piece 6, so as to meet different degrees of crushing effects on the material, and in later use, it can effectively improve the replacement efficiency of the crushing piece 61 and improve the working stability and efficiency of the equipment.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
