DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present application.

[0018] See also Figure 1-Figure 9The present invention provides a pulverizing device for livestock and poultry feed processing, comprising a workbench 1, a shell 2 fixedly mounted on the workbench 1, a filter cartridge 3 fixed in the shell 2, and a pulverizing assembly 4 rotatably arranged in the filter cartridge 3, wherein a feed channel 31 extending to the interior of the filter cartridge 3 is arranged at the top of the filter cartridge 3, and the feed channel 31 penetrates the shell 2 and is fixedly connected to a feed hopper 32, and a discharge port 21 is arranged at the bottom of the shell 2.

[0019] When in use, the crushing component 4 is started to rotate, and then the feed to be crushed is poured into the feed hopper 32. Under the action of gravity, the feed to be crushed continuously enters the filter cartridge 3 through the feed channel 31 and is hit by the high-speed rotating crushing component 4, so that the feed is crushed into fine particles. Among them, the feed that meets the particle size requirement is discharged from the discharge port 21 after passing through the filter cartridge 3, while the feed that does not meet the particle size requirement remains in the filter cartridge 3 and continuously collides with the crushing component 4 under the drive of the circulation layer formed by the high-speed rotation of the crushing component 4 until it meets the particle size requirement and passes through the filter cartridge 3 and is discharged from the discharge port 21.

[0020] Specifically, combined Figure 2 , Figure 4 and Figure 6 As shown, the crushing assembly 4 includes a driving shaft 41 coaxially rotatably assembled in the filter cartridge 3, a pair of fixed disks 42 fixedly assembled on the driving shaft 41, and a fixed shaft 43 uniformly arranged on the fixed disk 42 along the circumferential direction, and a hammer 44 is uniformly rotatably connected to the fixed shaft 43 along its length direction. One end of the driving shaft 41 passes through the filter cartridge 3 and the outer casing 2 and is connected to a motor 45 fixed on the workbench 1.

[0021] When in use, the motor 45 drives a pair of fixed disks 42 to rotate through the drive shaft 41. Under the action of centrifugal force, the hammer 44 is transformed into a working posture (that is, the hammer 44 is transformed into a posture set along the radial direction of the fixed disk 42). The hammer 44 in the working posture collides with the feed to crush the feed.

[0022] In order to improve the pulverizing efficiency of the device and thus improve the efficiency of livestock and poultry feed processing, in this embodiment, the livestock and poultry feed processing pulverizing device further includes a reverse throwing component disposed on the filter cartridge 3; Figure 6 As shown, the filter cartridge 3 includes a columnar enclosure 33 and sealing plates 34 detachably mounted on both ends of the columnar enclosure 33. The columnar enclosure 33 and the two sealing plates 34 together form a crushing chamber 35. The feed channel 31 is vertically arranged on one side of the upper half of the columnar enclosure 33. Please continue reading Figure 6As shown, the columnar enclosure 33 includes arc plates 331 and arc strips 332 spaced apart in the circumferential direction, the arc strips 332 are provided with through grooves 333 in the thickness direction thereof, each through groove 333 is provided with the reverse casting assembly, and the arc plate 331 is provided with a first sieve hole 3311; Please continue reading Figure 6 As shown, the reverse casting assembly includes a casting plate 52 rotatably assembled in the through slot 333 via a rotating shaft 51, and a driving component 53 for driving the casting plate 52 to swing back and forth between a first position and a second position around the central axis of the rotating shaft 51, wherein the rotating shaft 51 is arranged along the axial direction of the filter cartridge 3, and the rotating shaft 51 is arranged at one end of the casting plate 52, when the casting plate 52 is at the first position, as shown in FIG. Figure 5 As shown, an interception groove 54 is formed in the through groove 333 on the side of the throwing plate 52 close to the crushing chamber 35, and the depth of the interception groove 54 increases continuously from one end to the other end of the rotating shaft 51 of the throwing plate 52. When the throwing plate 52 is in the second position, the side of the throwing plate 52 close to the crushing chamber 35 and the inner wall of the crushing chamber 35 are on the same arc surface (not shown). When the throwing plate 52 rotates from the first position to the second position, the rotation direction of the throwing plate 52 is opposite to the rotation direction of the crushing assembly 4 when it is working.

[0023] Based on the above arrangement, in the process of crushing, the driving component 53 can drive the throwing plate 52 to swing back and forth quickly between the first position and the second position around the central axis of the rotating shaft 51. When the throwing plate 52 is at the first position, the through groove 333 of the throwing plate 52 close to the side of the crushing chamber 35 can form an interception groove 54; the interception groove 54 can temporarily intercept part of the feed driven by the circulating layer, and in the process of the throwing plate 52 moving from the first position to the second position, a force is given to the temporarily intercepted feed in the opposite direction of the rotation direction of the crushing component 4, so that the feed collides with the crushing component 4 in the opposite direction and quickly, thereby increasing the number of collisions between the feed and the crushing component 4 and the collision impact force, thereby improving the crushing efficiency of the device, so as to improve the processing efficiency of livestock and poultry feed.

[0024] It should be supplemented that, since a reverse throwing assembly is provided in each through groove 333, and when the throwing plate 52 swings to the second position, the side of the throwing plate 52 close to the crushing chamber 35 is on the same arc surface as the inner wall of the crushing chamber 35; therefore, during the crushing process, when the throwing plate 52 at a certain position swings to the second position, that is, the interception groove 54 disappears at this location, the reverse throwing assembly at this location will not intercept the feed, so that the feed can move to the next reverse throwing assembly for reverse throwing operation, so that each part of the filter cartridge 3 can filter the crushed feed, avoiding frequent throwing of feed by a reverse throwing assembly at a certain location, resulting in the filter cartridge 3 at this location colliding with the feed for a long time (after the feed collides with the crushing assembly 4, it will change direction and hit the inner wall of the filter cartridge 3), shortening the service life of the filter cartridge 3.

[0025] like Figure 5 As shown, in this embodiment, the casting plate 52 includes a cylindrical portion 521 and a plate-like portion 522, wherein the rotating shaft 51 coaxially passes through the cylindrical portion 521, and the rotating shaft 51 and the cylindrical portion 521 form a circumferential locking structure through a key groove. During the rotation of the casting plate 52, the outer circumferential surface and both end surfaces of the cylindrical portion 521 are tightly attached to the inner wall of the through groove 333, and the two side surfaces of the plate-like portion 522 and the end surface away from the cylindrical portion 521 are tightly attached to the inner wall of the through groove 333.

[0026] like Figure 5 As shown, in this embodiment, the throwing plate 52 is evenly provided with second sieve hole slots 523 of the same size as the first sieve hole 3311. When the feed that meets the particle size requirement enters the interception slot 54, the second sieve hole slots 523 allow the feed that meets the particle size requirement to pass through, thereby increasing the amount of feed that does not meet the particle size requirement in the interception slot 54, thereby further improving the crushing efficiency of the device.

[0027] like Figure 6-Figure 8 As shown, in this embodiment, the driving component 53 includes an annular slideway structure 531 and a swing structure 532; The annular slideway structure 531 is fixedly connected to the drive shaft 41, and the annular slideway structure 531 is arranged between one end of the filter cartridge 3 and the outer shell 2, and the annular slideway structure 531 includes an inner ring body 5311 fixedly assembled on the drive shaft 41, an outer ring body 5312 coaxially arranged outside the inner ring body 5311, and a connecting plate body 5313 uniformly arranged between the inner ring body 5311 and the outer ring body 5312 along the circumferential direction; At least one triangular groove 5314 is disposed on the outer ring surface of the outer ring body 5312, and the depth of the triangular groove 5314 decreases gradually along the rotation direction of the driving shaft 41; One end of each rotating shaft 51 close to the annular slide structure 531 passes through the corresponding arc bar 332 and is connected to the swing structure 532. The swing structure 532 includes a swing rod 5321 fixedly connected to the rotating shaft 51. The end of the swing rod 5321 away from the rotating shaft 51 is rotatably provided with a resistance wheel 5322. The swing structure 532 also includes a pre-tightening spring 5323 that gives the swing rod 5321 an elastic force to make the resistance wheel 5322 tightly adhere to the outer ring surface of the outer ring body 5312.

[0028] Based on the above arrangement in this embodiment, when the motor 45 drives the driving shaft 41 to rotate so that the hammer 44 crushes the feed, the driving shaft 41 can synchronously drive the inner ring body 5311 and the outer ring body 5312 to rotate. During this process, the swing rod 5321 is subjected to the force of the preload spring 5323, and the abutting wheel 5322 at one end of the swing rod 5321 always abuts against the outer ring surface of the outer ring body 5312. During this process, the throwing plate 52 is in the second position. As the outer ring body 5312 continues to rotate, when the triangular groove body 5314 on the outer ring body 5312 moves to the position of the abutment wheel 5322, under the elastic force of the preload spring 5323, the rotating shaft 51 will deflect and cause the throwing plate 52 to move quickly from the second position to the first position, thereby giving a thrust to the feed in the intercepting groove 54, causing the feed to reverse and quickly collide with the crushing component 4, thereby improving the crushing efficiency of the feed.

[0029] That is, after the motor 45 is started, the throwing plate 52 can automatically swing rapidly between the first position and the second position to throw the feed, thereby increasing the number of collisions and the collision impact force between the feed and the crushing assembly 4, thereby improving the crushing efficiency of the feed.

[0030] In this embodiment, an end of the swing rod 5321 away from the roller is provided with an axial hole adapted to the rotating shaft 51, and a first stop screw 53211 penetrating into the axial hole is also provided on the swing rod 5321 at the position of the axial hole. The actual crushing requirement of the present invention is to change the first position and the second position of the throwing plate 52 in the through groove 333 by releasing the locking of the first stop screw 53211 and changing the relative angle between the swing rod 5321 and the throwing plate 52, so as to increase the depth of the interception groove 54 and the deflection angle of the throwing plate 52.

[0031] In this embodiment, the outer ring body 5312 includes first arc plates 331 uniformly arranged along the circumferential direction, and there is a spacing between adjacent first arc plates 331, and each first arc plate 331 is fixedly connected to the inner ring body 5311 through the connecting plate body 5313; The outer ring body 5312 also includes a second arc plate 331 with one end rotatably arranged within the spacing via a rotating shaft 53122. The second arc plate 331 is rotatably connected to the first arc plate 331 via the rotating shaft 53122, and the end of the second arc plate 331 away from the rotating shaft 53122 contacts one end of the adjacent first arc plate 331. The second arc plate 331 has a third angle and a fourth angle during its rotation around the center line of the rotating shaft 53122. When the second arc plate 331 is at the third angle, the outer arc surface of the second arc plate 331 and the outer arc surface of the first arc plate 331 are on the same arc surface. When the second arc plate 331 is at the fourth angle, the outer arc surface of the second arc plate 331 and the end face of the first arc plate 331 that contacts the end away from the rotating shaft 53122 form a triangular groove body 5314.

[0032] In this embodiment, a limiting block 53124 is fixed to one side of the second arc plate 331 away from one end of the rotating shaft 53122 , and a second limiting screw 53125 is threadedly connected to the limiting block 53124 .

[0033] Based on the above-mentioned settings, during use, the operator can adaptively adjust the angles of several second arc plates 331 to form different numbers of triangular grooves 5314 on the outer ring surface. For example, when the second arc plate 331 is adjusted to the third angle, the triangular groove 5314 disappears correspondingly; when the second arc plate 331 is adjusted to the fourth angle, a triangular groove 5314 is formed correspondingly.

[0034] In addition, the operator can also adaptively increase or decrease the depth of the triangular trough 5314 by changing the deflection angle of the second arc plate 331 to adaptively meet the crushing requirements.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
