Energy-saving type pulverizing device for animal feed processing

Abstract

This invention discloses an energy-saving pulverizing device for animal feed processing, belonging to the field of animal feed preparation technology. It includes a base plate with a support frame fixedly connected to it, and a pulverizing assembly mounted on the support frame. In this invention, coarse particles that do not meet the particle size requirements fall into the feed hopper through a discharge cylinder under gravity and vibration. Subsequently, the drive shaft of the pulverizing assembly starts to rotate, driving the first roller to rotate and transmitting power to the second roller via a belt. The second roller synchronously drives the long rod and its connected rotating roller to rotate, thereby driving the conveyor belt to complete the transmission of the hopper. When the hopper reaches the lower end of its cyclical movement, it scrapes the unqualified material from the feed hopper. When it rotates to the top flipping position, it throws the material into the baffle box by inertia, and finally enters the conveyor pipe through the discharge port, returning to the pulverizing assembly again, thus realizing the automatic recovery and repeated pulverizing of unqualified materials.

Description

Technical Field

[0001] This invention belongs to the field of animal feed preparation technology, and in particular relates to an energy-saving pulverizing device for animal feed processing. Background Technology

[0002] Animal feed is processed through steps such as pretreatment, crushing, mixing, and pelleting. The crushing step is a critical initial step, aiming to refine the raw material particles to the target particle size range. Therefore, it is necessary to equip the feed with a high-efficiency and stable crushing device to meet the processing requirements of different raw material hardness and particle size.

[0003] In existing technologies, animal feed raw materials are often not completely crushed during the crushing process, resulting in a large number of coarse particles that do not meet the standard particle size in the output. If these coarse particles are not effectively separated, they are difficult to meet the requirements of subsequent processes or product quality. At present, it usually relies on manual screening and recycling of unqualified particles and re-grinding them. This is not only cumbersome and labor-intensive, but also reduces the overall production efficiency.

[0004] Based on this, the present invention designs an energy-saving pulverizing device for animal feed processing to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the problem that in the existing technology, animal feed raw materials are often not thoroughly ground during the grinding process, resulting in the presence of a large number of coarse particles that do not meet the required particle size in the output. If these coarse particles are not effectively separated, they are difficult to meet the requirements of subsequent processes or product quality. Currently, the unqualified particles are usually screened and recycled manually and then put back into the grinding process, which is not only cumbersome and labor-intensive, but also reduces the overall production efficiency. Therefore, this invention proposes an energy-saving grinding device for animal feed processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving pulverizing device for animal feed processing includes a base plate, a support frame fixedly connected to the base plate, a pulverizing component mounted on the support frame, a drive component fixedly connected to the support frame, the drive component mounted outside the pulverizing component, a drive shaft fixedly connected inside the pulverizing component, a screening device fixedly connected inside the support frame, a conveying device fixedly connected to the base plate, a feeding device fixedly connected outside the conveying device, and a receiving plate fixedly connected to the base plate. The screening device includes a screen plate, a vibrating motor is fixedly connected to the outside of the screen plate, and rotating shafts are symmetrically installed on the outside of the screen plate, with the rotating shafts rotatably connected inside the support frame; The transmission device includes a processing box, which is fixedly connected to a base plate. Two rotating rollers are rotatably connected inside the processing box. The two rotating rollers are covered with the same conveyor belt, and a bucket box is fixedly connected to the outside of the conveyor belt.

[0007] As a further description of the above technical solution: The screening device also includes two rotating shells, with a connecting shaft running through each rotating shell. The two connecting shafts are symmetrically installed outside the screen plate. A sliding rod is slidably connected inside each rotating shell, and a locking rod is running through each sliding rod. A return spring is fitted over the sliding rod. A discharge cylinder runs through the screen plate.

[0008] As a further description of the above technical solution: One end of the pull-back spring is fixedly connected to the outside of the slide rod, and the other end of the pull-back spring is fixedly connected to the outside of the rotating housing.

[0009] As a further description of the above technical solution: The connecting shaft and the rotating housing form a rotatable connection, and the slide rod and the locking rod form a rotatable connection.

[0010] As a further description of the above technical solution: The sieve plate is set at a certain angle and the side with the discharge cylinder is inclined downward.

[0011] As a further description of the above technical solution: The transmission device also includes a first reel and a second reel. The first reel is fixedly connected to one end of the drive shaft. A long rod is connected through the second reel. The first reel and the second reel are covered with the same belt. The long rod and the processing box are rotatably connected. The long rod is fixedly connected to the upper rotating roller. A feed hopper is fixedly connected to one side of the processing box.

[0012] As a further description of the above technical solution: The bottom surface of the processing box is set as a semi-circle, and the bucket-shaped box overlaps the outside of the semi-circle.

[0013] As a further description of the above technical solution: The discharge cylinder is L-shaped, and the discharge end of the discharge cylinder is above the feed hopper.

[0014] As a further description of the above technical solution: The feeding device includes a baffle box, which is fixedly connected to one side of the processing box. A receiving box is installed under the baffle box, and a discharge port is opened in the receiving box. A conveying pipe is fixedly connected to the discharge port.

[0015] As a further description of the above technical solution: The material transfer tube is inclined at a certain angle, and the discharge end of the material transfer tube is located above the feed inlet of the crushing component.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the processed material first enters the screen plate. Then, by starting a vibration motor, the screen plate is driven to vibrate at a high frequency. During vibration, the periodic impact force generated by the screen plate acts on the sliding rod, causing it to slide back and forth within the rotating shell, while simultaneously compressing the return spring. At the same time, the rotating shaft rotates synchronously within the support frame. Under the elastic action of the return spring, the sliding rod receives a reverse restoring force and slides along the direction of the rotating shell to quickly return the screen plate to its initial position, forming a continuous vibration cycle. During this process, the material is effectively screened through the continuous shaking of the screen plate, separating coarse particles that do not meet the particle size requirements. Under the influence of gravity and vibration, the material falls into the feed hopper through the discharge cylinder. Subsequently, the drive shaft of the crushing component starts to rotate, driving the first reel to rotate and transmitting power to the second reel via a belt. The second reel synchronously drives the long rod and its connected rotating roller to rotate, thereby driving the conveyor belt to complete the transmission of the hopper. When the hopper rotates to the lower end, it scrapes the unqualified material in the feed hopper. When it rotates to the top flip position, it throws the material into the baffle box by inertia. Finally, it enters the conveyor pipe through the discharge port and returns to the crushing component, realizing the automatic recycling and repeated crushing of unqualified materials.

[0017] 2. In this invention, when the drive motor is working, the drive shaft starts to rotate, driving the first reel to run at a set speed. The first reel efficiently transmits power to the second reel via a belt, completing the mechanical energy conversion from horizontal to vertical. The rotation of the second reel further drives the connected long rod and its associated rotating roller to rotate synchronously, realizing continuous drive of the conveyor belt. At the same time, it pushes the bucket box to run stably along the conveyor path. In the entire transmission process, only a single motor can complete the drive control of multiple key functional components such as crushing, screening, material return, and circulating conveying. This greatly simplifies the power system structure of the device, reduces energy consumption, and improves system integration and operating efficiency, resulting in significant energy-saving effects and practical value.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-6 The present invention provides a technical solution: an energy-saving crushing device for animal feed processing, comprising a base plate 1, a support frame 2 fixedly connected to the base plate 1, a crushing component 3 installed on the support frame 2, a drive component 4 fixedly connected to the support frame 2, the drive component 4 installed outside the crushing component 3, a drive shaft 5 fixedly connected inside the crushing component 3, a screening device 6 fixedly connected inside the support frame 2, a conveying device 7 fixedly connected to the base plate 1, a feeding device 8 fixedly connected outside the conveying device 7, and a receiving plate 9 fixedly connected to the base plate 1; The screening device 6 includes a screen plate 61, a vibrating motor 69 fixedly connected to the outside of the screen plate 61, and rotating shafts 67 symmetrically installed on the outside of the screen plate 61. The rotating shafts 67 are rotatably connected to the support frame 2. The transmission device 7 includes a processing box 75, which is fixedly connected to the base plate 1. Two rotating rollers 76 are rotatably connected inside the processing box 75. The two rotating rollers 76 are covered with the same transmission belt 77, and a bucket box 78 is fixedly connected to the outside of the transmission belt 77.

[0022] Specifically, such as Figures 2-4 As shown, the screening device 6 also includes two rotating shells 63, with connecting shafts 62 running through them. The two connecting shafts 62 are symmetrically installed outside the screen plate 61. A sliding rod 64 is slidably connected inside the rotating shell 63, and a locking rod 65 runs through it. A return spring 66 is sleeved on the outside of the sliding rod 64. By providing a continuous elastic restoring force during the reciprocating sliding of the sliding rod 64, the sliding rod 64 can quickly return to its initial position after displacement caused by screening vibration. This structural design not only improves the vibration frequency and stability of the screen plate 61, but also simplifies the reciprocating drive structure of the sliding rod 64, achieving efficient screening while reducing component wear. A discharge cylinder 68 is connected through the screen plate 61. One end of the return spring 66 is fixedly connected to the outside of the slide rod 64, and the other end of the return spring 66 is fixedly connected to the outside of the rotating shell 63. A rotating connection is formed between the connecting shaft 62 and the rotating shell 63, and a rotating connection is formed between the slide rod 64 and the locking rod 65. The screen plate 61 is set to be inclined at a certain angle, and the side with the discharge cylinder 68 is inclined downward. The discharge cylinder 68 is perpendicular to the inclined screen plate 61 and is set on its lower side. During the vibration of the screen plate 61, large particles that do not pass through the screen holes will converge along the inclined direction and be discharged under the action of gravity and inertia. This structural design realizes the integration of screening and directional discharge, avoids powder backflow or blockage, and improves screening efficiency and continuity.

[0023] Specifically, such as Figure 5-6 As shown, the transmission device 7 also includes a first reel 71 and a second reel 72. The first reel 71 is fixedly connected to one end of the drive shaft 5, and the second reel 72 is internally connected to a long rod 74. The first reel 71 and the second reel 72 are covered by the same belt 73. The belt 73 is simultaneously wrapped around the first reel 71 and the second reel 72, forming a stable synchronous transmission structure. This allows the power of the drive shaft 5 to be smoothly transmitted to the transmission roller system below. This structural design realizes the integration of multi-stage transmission functions, which not only saves layout space but also avoids the problems of increased energy consumption and complex control caused by multi-motor drive. The long rod 74 and the processing box 75 are rotatably connected. The long rod 74 is fixedly connected to the upper rotating roller 76. A feed hopper 79 is fixedly connected to one side of the processing box 75. The bottom surface of the processing box 75 is set as a semi-circle, and the hopper box 78 overlaps the outside of the semi-circle. The hopper box 78 overlaps the semi-circular bottom surface set inside the processing box 75 and runs in the semi-circular track with the conveyor belt 77. It can efficiently scrape the recycled material at the bottom and stably bear it. This structural design uses the geometric features of the bottom surface to assist in material collection and positioning, making the recycling process smoother and effectively avoiding material residue or leakage. The discharge cylinder 68 is L-shaped, and the discharge end of the discharge cylinder 68 is above the feed hopper 79.

[0024] Specifically, such as Figure 2 and Figure 6 As shown, the feeding device 8 includes a baffle box 81, which is fixedly connected to one side of the processing box 75. A receiving box 82 is installed under the baffle box 81. A discharge port 83 is opened in the receiving box 82. A conveying pipe 84 is fixedly connected in the discharge port 83. The conveying pipe 84 is set in an inclined state with a certain angle, and the discharge end of the conveying pipe 84 is above the feed port of the crushing component 3. The conveying pipe 84 is fixedly connected to the discharge port 83 of the receiving box 82 and is set in an inclined state, so that the material flows into the feed port of the crushing component 3 under the action of gravity, realizing non-powered feeding. This structure makes full use of the height difference and the material gravity flow characteristics, and can realize the secondary feeding of materials without additional transmission devices. The structure is simple and the operation is efficient.

[0025] Working principle and usage: The processed material first enters the screen plate 61. Then, by starting the vibration motor 69, the screen plate 61 is driven to generate high-frequency up-and-down vibration. During the vibration, the periodic impact force generated by the screen plate 61 acts on the slide rod 64, causing it to slide back and forth within the rotating shell 63, while simultaneously compressing the return spring 66. At the same time, the rotating shaft 67 rotates synchronously within the support frame 2. Under the elastic action of the return spring 66, the slide rod 64 obtains a reverse restoring force and slides along the direction of the rotating shell 63 to drive the screen plate 61 to quickly return to its initial position, forming a continuous vibration cycle. During this process, the material is effectively screened by the continuous shaking of the screen plate 61, and coarse particles that do not meet the particle size requirements are separated by heavy... Under the action of force and vibration, the material falls into the feed hopper 79 through the discharge cylinder 68. Then, the drive shaft 5 of the crushing component 3 starts to operate, driving the first winding wheel 71 to rotate, and transmitting power to the second winding wheel 72 through the belt 73. The second winding wheel 72 synchronously drives the long rod 74 and its connected rotating roller 76 to rotate, thereby driving the conveyor belt 77 to run, completing the driving and transmission of the bucket box 78. When the bucket box 78 circulates to the lower end, it scrapes the unqualified material in the feed hopper 79, and when it rotates to the top flip position, it throws the material into the baffle box 81 by inertia. Finally, it enters the conveyor pipe 84 through the discharge port 83 and returns to the crushing component 3, realizing the automatic recycling and repeated crushing of unqualified materials.

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