DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described 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; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] In the process of poultry farming, it is necessary to mix a variety of materials together and grind them to form nutritionally uniform feed. Generally, the various materials are directly put into the inside of the grinding box, and then the grinding mechanism in the grinding box grinds them. This results in different particle sizes of the various materials after grinding, and the materials of different particle sizes are unevenly distributed when they pile up after falling. Some methods ensure the particle size of the materials through screening with a screen, but the screen is prone to clogging after long-term use, thereby reducing the effective screening area of the screen. Therefore, the above technical problems need to be solved.

[0032] Depend on Figures 1-8 The present invention relates to a feed mixing and crushing device for poultry breeding, comprising a cart 1 with a power unit, a crushing shell 5 with a feed hopper 3 and a discharge hopper 4 fixed on the cart 1, a rotating shaft 6 with a crushing blade 7 rotating inside the crushing shell 5, a screen unit fixed on the rotating shaft 6, the screen unit comprising a circular plate 8, an annular outer screen 9, an annular inner screen 10 and a plurality of adaptive parts, the circular plate 8 is fixed on the rotating shaft 6 and connected to the outer screen 9 as a whole, the inner screen 10 is located on the inner side of the outer screen 9 and is connected to the outer screen 9 through a plurality of adaptive parts, and a baffle 11 is fixed to the inner wall of the crushing shell 5.

[0033] With this design, when in use, the power unit is first used to drive the rotating shaft 6 to rotate, and the rotating shaft 6 drives the crushing blade 7 thereon to rotate. At the same time, the rotating shaft 6 drives the outer screen 9 to rotate through the circular plate 8, and the outer screen 9 drives the inner screen 10 to rotate through multiple adaptive parts. The material is put into the interior of the crushing shell 5 through the feed hopper 3, so that the material is placed on the inner side of the inner screen 10 in the screen unit. The inner screen 10 drives the material therein to rotate through centrifugal force during the rotation process. When the material rotates to the upper part of the inner screen 10, the material is blocked by the baffle 11 and falls down. In the process of material discharge, it can be crushed by the crushing blade 7 on the rotating shaft 6. The crushing operation is carried out, and the crushing blade 7 also crushes part of the material located below the inner screen 10, so that the material with smaller particles after crushing will pass through the inner screen 10 and the outer screen 9 and fall into the interior of the crushing shell 5 and then be discharged through the discharge hopper 4, while the material with larger particles continues to remain in the interior of the inner screen 10 and be crushed until it reaches a suitable particle size; since the movement trajectory of the material is below the inner screen 10, it then rotates with the inner screen 10 to form a circumferential motion, and is finally blocked by the baffle 11 and falls and is crushed by the crushing blade 7, thereby forming a circular movement trajectory, which can effectively make the materials evenly mixed together.

[0034] Specifically, the inner screen 10 includes multiple arc-shaped orifice plates 12 and multiple elastic strips 13, which are alternately arranged and connected as a whole; the sieve holes on the arc-shaped orifice plates 12 are connected to the sieve holes on the outer screen 9 through adaptive parts.

[0035] The adaptive member includes a plurality of arcuate pieces 14 and a plurality of arcuate bars 15, which are alternately arranged and connected as a whole; the middle portions of the arcuate pieces 14 and the arcuate bars 15 both protrude from the outside of the adaptive member to the inside thereof.

[0036] When the inner screen 10 rotates with the outer screen 9, the inner screen 10 gradually approaches the outer screen 9 under the action of the centrifugal force. Specifically, under the action of the elastic strip 13, the arc-shaped orifice plate 12 squeezes the arc-shaped piece 14 after approaching the outer screen 9, so that the middle aperture formed by the plurality of arc-shaped pieces 14 gradually becomes smaller and eventually reaches the aperture size during screening. In this way, materials smaller than the aperture size can pass through the middle hole formed by the arc-shaped pieces 14, while materials larger than the aperture size continue to remain in the inner screen 10 for crushing operation; and after the crushing operation is completed, the inner screen 10 no longer rotates. At this time, under the action of the plurality of arc-shaped pieces 14, the middle aperture formed by the plurality of arc-shaped pieces 14 gradually becomes larger and returns to the original aperture size. In this way, due to the change in aperture, the blockage of the inner screen 10 can be effectively reduced.

[0037] In short, after the device is started, the effective screening aperture between the inner screen 10 and the outer screen 9 becomes smaller to facilitate the screening operation, and after the device is stopped, the effective screening aperture between the inner screen 10 and the outer screen 9 becomes larger, thereby effectively reducing the possibility of blockage during screening.

[0038] Specifically, the arc-shaped orifice plate 12 and the arc-shaped sheet 14 are both made of stainless steel, and the elastic strip 13 and the arc-shaped strip 15 are both made of wear-resistant rubber.

[0039] Specifically, support columns 16 are formed at both ends of one side of the cart 1, and movable wheels 17 are fixed at both ends of the other side of the cart 1. This design allows the cart 1 to contact the ground through the support columns 16 to improve the stability of the device during operation, while the movable wheels 17 can move the device so that it can be moved to a desired location, which is more suitable for farms with larger areas.

[0040] Specifically, the power unit includes a drive motor 18, a driving pulley 19, a driven pulley 20 and a transmission belt 21. The drive motor 18 is fixed on the cart 1 and its output shaft is fixed to the driving pulley 19. The driven pulley 20 is fixed on the rotating shaft 6 and is connected to the driving pulley 19 through the transmission belt 21. The rotating shaft 6 is rotatably arranged on the cart 1.

[0041] In this design, the driving motor 18 drives the active pulley 19 to rotate, the active pulley 19 drives the driven pulley 20 to rotate through the transmission belt 21, and the driven pulley 20 drives the rotating shaft 6 to rotate, thereby realizing the driving process of the crushing blade 7.

[0042] Furthermore, in order to facilitate the transportation of materials from the feed hopper 3 to the inner side of the inner screen 10 in the crushing shell 5, a cylinder 22 is fixed on the crushing shell 5 along its axial direction, and the cylinder 22 is connected to the crushing shell 5, the feed hopper 3 is fixed on the cylinder 22 and connected thereto, and a spiral blade 23 is fixed on the rotating shaft 6 located in the cylinder 22.

[0043] With this design, when in use, the material falls from the feed hopper 3 into the interior of the cylinder 22, and the spiral blade 23 is driven to rotate during the rotation of the rotating shaft 6, and the spiral blade 23 pushes the material in the cylinder 22, so that the material falls from the cylinder 22 to the inner side of the inner screen 10.

[0044] Specifically, the baffle 11 is located inside the inner screen 10 and is fitted to the inner screen 10 . The baffle 11 is fixed to the pulverizing shell 5 via at least one connecting rod 24 .

[0045] A discharge cavity 25 is formed between the outer screen 9 and the crushing shell 5, and the discharge hopper 4 is fixed to the bottom end of the crushing shell 5 and communicates with the discharge cavity 25. In this design, the screened material can be discharged into the discharge cavity 25 and then discharged through the discharge hopper 4.

[0046] Furthermore, taking into account that the material specifications required are sometimes different, an inner groove 26 is formed in the rotating shaft 6, and an adjusting column 27 is connected to the inner thread of the inner groove 26. A plurality of pull ropes 28 are fixed on the adjusting column 27. The corresponding pull ropes 28 pass through the rope holes on the rotating shaft 6 and the rope holes on the arc-shaped orifice plate 12 and are placed between the outer screen 9 and the inner screen 10, and an anti-slip column 29 is fixed on the pull rope 28 located between the outer screen 9 and the inner screen 10; a multi-prism 30 is formed at one end of the adjusting column 27, and a locking nut 2 is threadedly connected to the adjusting column 27.

[0047] With this design, when it is necessary to adjust the effective screening aperture of the material by the adjustment device, it is only necessary to loosen the locking nut 2, and then operate the polygonal column 30 with a tool to rotate the adjusting column 27, and reel the pull rope 28 through the adjusting column 27, and the pull rope 28 drives the anti-detachment column 29 to move, so as to achieve the purpose of adjusting the position of the anti-detachment column 29, so as to adjust the maximum displacement distance of the inner screen 10 under the action of centrifugal force, thereby adjusting the deformation of the arc-shaped sheet 14 in the adaptive part to achieve the effective aperture size during screening. After the adjustment is completed, it can be locked by the locking nut 2.

[0048] It should be noted that scale boxes and indicator lines can be provided on the rotating shaft 6 and the adjusting column 27 respectively, so as to ensure the accuracy after adjustment.

[0049] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
