Description

Technical Field

[0001] This utility model relates to the field of feed production, and in particular to a feed production hopper. Background Technology

[0002] In the field of feed production, the hopper is one of the core devices for the temporary storage and continuous conveying of feed raw materials. Its performance directly affects the operating efficiency and stability of the entire production line. Because feed raw materials usually have characteristics such as uneven particle size, a certain amount of moisture that makes them prone to clumping or strong stickiness, during the feeding and conveying process through the hopper, the raw materials are very likely to accumulate and bridge on the inner wall of the hopper, especially at the discharge port, which can lead to blockage problems.

[0003] To solve the aforementioned hopper clogging problem, most existing technologies employ the installation of a stirring device at the hopper. The rotation of the stirring device agitates and disperses the feed ingredients in the hopper, thereby disrupting the material's aggregate structure, maintaining its fluidity, and thus preventing the feed from clogging the hopper. However, the above mixing method has obvious defects: the high-speed rotation or rigid mixing action of the mixing device can easily break the feed particles and destroy the original particle structure of the feed. This will not only lead to a decrease in the uniformity of the finished feed particles and affect the product quality, but may also cause new problems such as secondary dust or poor feeding due to the increase in fine powder. Utility Model Content

[0004] The purpose of this utility model is to provide a feed production hopper in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feed production hopper, comprising a hopper shell that is wider at the top and narrower at the bottom, a preliminary filter assembly installed at the upper port of the hopper shell, a feed anti-blocking assembly installed at the lower port of the hopper shell, and a reciprocating conveying assembly installed between the preliminary filter assembly and the feed anti-blocking assembly; The reciprocating conveying assembly includes a cylinder body one coaxially fixedly connected to the inner side of the hopper shell, and conveying blades that rotate and convey feed inside the cylinder body one. The material discharge anti-blocking assembly includes a second cylinder coaxially fixedly installed at the bottom end of the first cylinder, and a push bucket that is reciprocally slidably installed between the inner side of the hopper shell and the outer side of the second cylinder.

[0006] As a further description of the above technical solution: the preliminary filtration assembly includes a filter bucket fixedly installed at the port of the hopper shell, and a plurality of sweeping arms rotatably installed on the filter bucket.

[0007] As a further description of the above technical solution: the first cylinder is connected to the filter hopper, and several support frames are fixedly installed in a ring array between the outer side of the first cylinder and the inner side of the hopper shell.

[0008] As a further description of the above technical solution: a plurality of agglomerated feed inlets are provided through the annular array on the lower side of the outer surface of the cylinder, a plurality of agglomerated discharge outlets are provided through the annular array on the lower side of the outer surface of the cylinder, and a shaft coaxially and fixedly connected to the conveying blade is rotatably installed at the axial center of the inner side of the cylinder.

[0009] As a further description of the above technical solution: a connecting ring is fixedly connected to the upper side of the outer surface of the shaft, and several of the sweeping arms are fixedly installed on the outside of the connecting ring.

[0010] As a further description of the above technical solution: symmetrical guide grooves are provided through the outer surface of the second cylinder, and a servo motor is fixedly connected to the bottom of the inner cavity of the second cylinder. A reciprocating lead screw is fixedly connected to the output shaft of the servo motor through a coupling, and the reciprocating lead screw is fixedly connected to the shaft.

[0011] As a further description of the above technical solution: a screw thread is threaded onto the outer surface of the reciprocating screw, and connecting rods are slidably connected to the inner surfaces of the two guide grooves. One side of the two connecting rods is fixedly connected to the outer surface of the screw thread, and the other side of the two connecting rods is fixedly connected to the lower end of the push bucket.

[0012] As a further description of the above technical solution: several spikes are fixedly installed in a ring array on the upper side of the pushing bucket.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: Feed pellets are filtered into the hopper shell through the preliminary filtration component. During this process, the feed pellets at the feed inlet of the hopper shell are reciprocated by the feed anti-clogging component. This effectively prevents the feed pellets from accumulating and clogging at the feed inlet of the hopper shell. The non-rigid reciprocating pushing method also reduces mechanical damage to the feed pellets. Compared with traditional rotary stirring, it can better maintain the original integrity and particle size uniformity of the feed pellets, reduce the amount of fine powder produced and the secondary problems caused by it. Agglomerated feed pellets that fail to be filtered by the primary filtration component are conveyed upwards by the reciprocating conveyor component and then automatically fall onto the feed anti-blocking component. Through multiple automatic drops, the agglomerated pellets are naturally broken up. This effectively breaks up the agglomerated pellets to prevent blockage, and because there is no rigid shearing force, it reduces additional damage to the feed pellets and further ensures the integrity of the feed pellets.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 - Figure 4 As shown, the present invention provides a feed production hopper, comprising a hopper shell 1 that is wider at the top and narrower at the bottom, a preliminary filter assembly 2 installed at the upper port of the hopper shell 1, a feed anti-blocking assembly 5 installed at the lower port of the hopper shell 1, and a reciprocating conveying assembly 4 installed between the preliminary filter assembly 2 and the feed anti-blocking assembly 5.

[0018] In actual use, the feed pellets first enter the processing flow through the preliminary filtration component 2. After preliminary filtration, they fall into the hopper shell 1. The preliminary filtration component 2 can initially guide and screen the pellets. During the process of the feed pellets moving towards the discharge port of the hopper shell 1, the discharge anti-blocking component 5 continuously pushes the pellets at the discharge port in a non-rigid reciprocating manner. This reciprocating pushing method can break the static accumulation trend of the pellets and effectively prevent the feed pellets from forming blockages at the key discharge position. At the same time, the non-rigid pushing avoids the hard mechanical impact generated by traditional rotation and stirring, minimizing the physical damage to the feed pellets, thereby maintaining the original integrity and uniformity of the pellets. For feed pellet clumps that fail to be filtered by the preliminary filter component 2, the reciprocating conveyor component 4 will transport them upward to a certain height. Then, the clumps will automatically fall under the action of gravity and land on the feed anti-blocking component 5. Through the cyclic conveying of the reciprocating conveyor component, the clumps will undergo multiple automatic falling processes, and the impact force during the fall will be used to achieve natural breakage. This breakage method does not require a rigid shear structure, which can not only completely break up the clumps to eliminate the risk of blockage, but also avoid damage to the pellets caused by additional mechanical force.

[0019] Specific examples Figures 1-3 As shown, the preliminary filtration assembly 2 includes a filter bucket 21 fixedly installed at the upper port of the hopper housing 1, and several sweeping arms 23 rotatably installed on the filter bucket 21. A connecting ring 22 is fixedly connected to the upper side of the outer surface of the shaft 44, and several sweeping arms 23 are fixedly installed on the outside of the connecting ring 22. Feed pellets fall into the outer shell 1 of the hopper through the filter holes on the filter hopper 21. When the feeding anti-blocking component 5 is working, it drives multiple sweeping arms 23 to rotate and spread the feed on the filter hopper 21, thereby preventing feed pellets from accumulating on the filter hopper 21.

[0020] Specific examples Figure 2 and Figure 3 As shown, the reciprocating conveying assembly 4 includes a cylindrical body 41 coaxially fixedly connected to the inner side of the hopper shell 1. The cylindrical body 41 is connected to the filter hopper 21, and several support frames 3 are fixedly installed in a ring array between the outer side of the cylindrical body 41 and the inner side of the hopper shell 1. A number of agglomerated feed inlets 42 are provided in a ring array on the lower outer surface of the cylinder 41, and a number of agglomerated discharge outlets 43 are provided in a ring array on the lower outer surface of the cylinder 41. A shaft 44 is rotatably installed at the axis on the inner side of the cylinder 41, and a conveying blade 45 is fixedly connected to the outer side of the shaft 44. When there is too much feed on the filter hopper 21, the feed particles cannot pass through the filter holes on the filter hopper 21 in time. The feed particles and feed particle clumps slide together into the cylinder 41 and fall into the outer shell of the hopper 1 through multiple clump discharge ports 43. When the feed particle clumps fall into the feed anti-blocking component 5 through the clump discharge ports 43, they are broken. If the feed particle clumps are not broken, they re-enter the cylinder 41 through the clump inlet 42 and are conveyed upward by the conveying blades 45, and fall downward again through the clump discharge ports 43.

[0021] Specific examples Figure 2 and Figure 4As shown, the feeding anti-blocking component 5 includes a second cylinder 51 coaxially fixedly installed at the bottom of the first cylinder 41. The outer surface of the first cylinder 41 is symmetrically provided with guide grooves 54. The bottom of the inner cavity of the second cylinder 51 is fixedly connected to a servo motor 52. The output shaft of the servo motor 52 is fixedly connected to a reciprocating screw 53 through a coupling. The reciprocating screw 53 is fixedly connected to the shaft 44. A push bucket 56 is slidably provided at the lower end of the hopper shell 1. A screw nut 531 is threadedly installed on the outer surface of the reciprocating screw 53. Connecting rods 55 are slidably connected to the inner surfaces of the two guide grooves 54. The two connecting rods 55 are fixedly connected to the outer surface of the screw nut 531. Start the servo motor 52, which drives the reciprocating screw 53 to rotate, thereby driving the screw nut 531 to move up and down reciprocally. The screw nut 531 drives the push bucket 56 at the feed outlet of the hopper shell 1 to move back and forth through the connecting rod 55, thus avoiding the accumulation of feed particles that block the feed outlet of the hopper shell 1. After the feed pellets fall onto the push bucket 56, they slide down again into the cylinder 41 due to the slope of the push bucket 56.

[0022] Furthermore, several spiked plates 561 are fixedly installed in a ring array on the upper side of the bucket 56; The barbed plate 561 can enhance the breaking effect of feed pellet clumps after they fall.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
