Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a feed crusher capable of screening materials. Background Art

[0002] In the breeding industry, breeders usually use crops such as grains and straw as feed to feed livestock and poultry. Since it is difficult for livestock and poultry to chew and swallow large crops such as grains and straw directly, breeders usually break the crops into particles that are easy for livestock and poultry to chew and swallow. The surface area of ​​the crops increases after being broken, so that livestock and poultry can better absorb the nutrients in the broken crops.

[0003] In order to ensure the crushing efficiency, breeders usually choose feed crushers to crush crops. Feed crushers use the high-speed rotation of the crushing blades to achieve the crushing function.

[0004] Since the distance between the crushing blades in the crusher is large, the crops cannot be fully crushed, and the particles obtained after the initial crushing cannot all meet the standards. In order to ensure that the size of the crushed particles meets the requirements, crops usually need to be crushed multiple times. If the crushed crops are directly put into the feed crusher for crushing, the particles that have already reached the size requirements will be crushed again, which undoubtedly reduces the crushing efficiency of the feed crusher and increases the crushing cost.

[0025] refer to Figures 1 to 4A siftable feed crusher according to a preferred embodiment of the utility model will be described in detail below. The siftable feed crusher is used to crush crops such as grains and straws to produce granular feed of a preset size.

[0026] The feed crusher capable of screening materials comprises an equipment body 10. The equipment body 10 comprises an equipment body 11. The equipment body 10 forms a feeding port 1001. The equipment body 11 forms a crushing chamber 1101 connected to the feeding port 1001, and crops to be crushed are put into the crushing chamber 1101 from the feeding port 1001.

[0027] The siftable feed crusher includes a crushing mechanism 20. The crushing mechanism 20 includes a crushing assembly 21 and a crushing drive 22. The crushing assembly 21 is connected to the crushing drive 22. The crushing assembly 21 is installed in the crushing chamber 1101. The crushing drive 22 is used to drive the crushing assembly 21, and the crushing assembly 21 is driven by the crushing drive 22 to crush the crops to be crushed that are put into the crushing chamber 1101 from the feeding port 1001.

[0028] Specifically, the crushing assembly 21 includes at least one crushing member 211 and a crushing rotating shaft 212, and the crushing member 211 is mounted on the crushing rotating shaft 212. The crushing rotating shaft 212 is connected to the crushing driving member 22. The crushing driving member 22 drives the crushing member 211 to rotate along the axial direction of the crushing rotating shaft 212 by driving the crushing rotating shaft 212, and the rotating crushing member 211 crushes the crops falling into the crushing chamber 1101.

[0029] Preferably, the axial direction of the crushing rotating shaft 212 extends vertically. The crushing assembly 21 is provided with a plurality of crushing members 211, and the plurality of crushing members 211 are distributed on the crushing rotating shaft 212 at intervals along the axial direction of the crushing rotating shaft 212, so that the crops to be crushed are cut and crushed in sequence by the plurality of crushing members 211 in the process of falling from the feeding port 1001 to the crushing chamber 1101, so that the crops are fully crushed.

[0030] In this embodiment, the crushing element 211 is implemented as a cutting blade, and the crushing driving element 22 is implemented as a motor.

[0031] Furthermore, the siftable feed crusher further comprises a sifting member 30. The sifting member 30 is mounted on the equipment body 11, and the sifting member 30 is disposed below the crushing assembly 21. The sifting member 30 forms a plurality of first sieve holes 301 of preset apertures, and the first sieve holes 301 allow the crushed crops with a particle size smaller than the aperture of the first sieve hole 301 to pass through the sifting member 30. In other words, the crops with a particle size smaller than the aperture of the first sieve hole 301 can pass through the sifting member 30 and be discharged from the equipment body 10, while the crushed crops with a particle size larger than the aperture of the first sieve hole 301 stay on the sifting member 30, thereby achieving the screening of the crushed crops.

[0032] In one embodiment, the particles screened by the screening element 30 can be directly eaten by livestock and poultry, and the crops with larger particle sizes retained on the screening element 30 need to be removed by the breeder, who then puts the removed crops into the crushing chamber 1101 from the feeding port 1001 again, so that the crops with larger particle sizes can be crushed for the second time by the crushing mechanism 20. Since the crops with a particle size reaching a preset size have been selected through the screening effect of the screening element 30 before the second crushing, the input amount of the second crushing is smaller than that of the first crushing, thereby reducing the operating energy consumption of the feed crusher capable of screening and improving the crushing efficiency.

[0033] Furthermore, the siftable feed crusher further comprises a conveying mechanism 40 , and the conveying mechanism 40 is obliquely mounted on the equipment body 10 .

[0034] The conveying mechanism 40 includes a conveying component 41. The conveying component 41 includes a conveying body 411. The conveying body 411 forms a conveying chamber 41101, a feed port 41102 communicating with the conveying chamber 41101, and a discharge port 41103 communicating with the conveying chamber 41101. The feed port 41102 is disposed above the screening member 30, and the discharge port 41103 is disposed to communicate with the crushing chamber 1101 of the equipment body 10.

[0035] In one embodiment, the conveying mechanism 40 further includes a suction pump 42. The suction pump 42 is arranged to be in communication with the conveying body 411. The suction pump 42 sucks the crops with larger particle sizes remaining on the screening member 30 from the feed port 41102 to the discharge port 41103 through the conveying chamber 41101 by negative pressure, so that the crops with larger particle sizes enter the crushing chamber 1101 through the discharge port 41103 and are crushed again by the crushing assembly 21.

[0036] Preferably, the conveying body 411 includes a first conveying part 4111 and a second conveying part 4112. The first conveying part 4111 is installed at one end of the second conveying part 4112. The first conveying part 4111 and the second conveying part 4112 together form the conveying chamber 41101. The first conveying part 4111 forms the feed port 41102. The second conveying part 4112 forms the discharge port 41103. The suction pump 42 is installed at the second conveying part 4112.

[0037] The conveying member 41 further includes a conveying member 412 and a driving member 413. The conveying member 412 is connected to the driving member 413. The driving member 413 is used to drive the conveying member 412 to rotate. One end of the conveying member 412 extends into the crushing chamber 1101 and is located above the screening member 30, and one end of the conveying member 412 away from the crushing chamber 1101 extends into the conveying cavity 41101 formed by the first conveying part 4111. The conveying member 412 rotated by the driving member 413 transports the crops with larger particle sizes screened by the screening member 30 from the feed port 41102 through the conveying cavity 41101 to the discharge port 41103, so that the crops with larger particle sizes can return to the crushing chamber 1101 to be crushed again by the crushing mechanism 20.

[0038] The utility model uses the conveying mechanism 40 to convey the crops with larger particle sizes from the feed inlet 41102 to the discharge outlet 41103, which eliminates the need for manual operation by the breeder, thereby improving the automation level of the sifting feed crusher and the crushing efficiency of the machine. In addition, the conveying member 412 can also move the crops retained on the sifting member 30 while conveying the crops, thereby accelerating the sifting of the crops by the sifting member 30.

[0039] In this embodiment, the transmission member 412 is implemented as a spiral blade. The driving member 413 is implemented as a motor.

[0040] Specifically, the crushed crops on the screening member 30 are transported by the conveying member 412 to the discharge port 41103 via the conveying chamber 41101, and then the crops at the discharge port 41103 are sucked by the suction pump 42 and transported to the discharge port 41103. The crops fall into the crushing chamber 1101 through the discharge port 41103 and continue to be crushed again by the crushing mechanism 20.

[0041] The feed crusher capable of screening materials further comprises a material blocking mechanism 50. The material blocking mechanism 50 comprises a material blocking member 51, a turning shaft 52 and a rotation driving member 53. The material blocking member 51 is arranged below the crushing member 211, and the material blocking member 51 is installed above the conveying mechanism 40. The turning shaft 52 is coaxially installed on the material blocking member 51. The turning shaft 52 is connected to the rotation driving member 53. The rotation driving member 53 drives the turning shaft 52 to rotate and drives the material blocking member 51 to rotate around the axial direction of the turning shaft 52.

[0042] The crops after being crushed by the crushing mechanism 20 fall onto the material blocking member 51 under the action of gravity. As the crushed crops are continuously accumulated above the material blocking member 51, they come into contact with the crushing member 211, so that the crops are repeatedly crushed by the crushing mechanism 20. After a preset time, the rotating driving member 53 drives the material blocking member 51 to rotate along the axial direction of the flip shaft 52, so that the crops carried by the material blocking member 51 fall onto the screening member 30 and are screened by the screening member 30, wherein the crops with a particle size greater than the aperture of the first sieve hole 301 are conveyed by the conveying mechanism 40 to the crushing chamber 1101 for secondary crushing.

[0043] In this embodiment, the rotation driving member 53 is implemented as a motor.

[0044] Preferably, the material blocking member 51 forms a plurality of second sieve holes 5101 of preset apertures. The second sieve holes 5101 allow crops with a particle size smaller than the aperture of the second sieve holes 5101 to pass through the material blocking member 51, thereby performing a primary screening of the crushed crops.

[0045] It can be understood that as the crops to be crushed are continuously fed from the feeding port 1001 into the crushing chamber 1101 and crushed by the crushing mechanism 20, the crops with a particle size larger than the second sieve hole 5101 are never able to pass through the second sieve hole 5101 and are accumulated on the blocking member 51, so that the subsequent crushed crops always stay on the blocking member 51 and are crushed by the crushing mechanism 20, so that the crops staying on the blocking member 51 are fully crushed.

[0046] Preferably, the device body 10 further includes a protrusion 12. The protrusion 12 is fixedly mounted on the inner wall of the device body 11. The protrusion 12 is located on the rotation trajectory of the material blocking member 51 driven by the rotating driving member 53 and flipped along the axial direction of the flip shaft 52. In this way, the material blocking member 51 collides with the protrusion 12 during the flipping process, causing the material blocking member 51 to vibrate, so that the crops resting on the material blocking member 51 fall down with the vibration of the material blocking member 51, preventing the crops on the material blocking member 51 from accumulating too much and blocking the second sieve hole 5101.

[0047] Furthermore, a feeding port 1002 is formed in the equipment body 10, and the feeding port 1002 is arranged below the screening member 30. The crops falling through the first sieve holes 301 formed by the screening member 30 can fall into the feeding port 1002, and the breeder moves the crushed crops out of the equipment body 10 from the feeding port 1002.

[0048] Preferably, the equipment body 10 also includes a material guide 13, which is obliquely installed on the outer wall of the equipment body 11, and the material guide 13 is connected to the discharge port 1002, so that the crops can slide from the discharge port 1002 to the material guide 13, making it convenient for the breeder to collect the crushed crops from the material guide 13.

[0049] More preferably, the equipment body 10 further includes at least two baffles 14. The two baffles 14 are installed on the equipment body 11 at intervals. A feeding channel 1102 is formed between the two baffles 14, and the feeding channel 1102 is connected with the feeding port 1001 and the crushing chamber 1101. The two baffles 14 face the crushing assembly 21 at one end away from the feeding port 1001, so that the crops to be crushed fall from the feeding port 1001 through the feeding channel 1102 to the crushing member 211 for crushing.

[0050] Since the baffle 14 is arranged at an angle, the debris generated during the crushing process of the crops is blocked by the inner wall of the feeding channel 1102 and cannot splash out from the feeding port 1001 .

[0051] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
