Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a feed screening device for feed processing. Background Technology

[0002] In the feed processing process, the uniformity of feed particle size directly affects the feeding effect and subsequent processing quality, so feed screening is one of the key processes.

[0003] Existing feed screening devices generally suffer from the following problems: First, insufficient grading and screening accuracy. Most devices use single-layer filters or multi-layer filters arranged in a straight line, making it difficult to accurately separate feeds of different particle sizes. Furthermore, feed accumulation can easily clog the filters, affecting the continuity of screening. Second, outdated discharge control methods rely heavily on manual operation, which cannot be precisely coordinated with the screening rhythm, easily leading to mixing of feeds of different specifications and reducing the purity of the finished product. Third, unreasonable vibration structure design results in uneven vibration force transmission and uncontrollable vibration amplitude, not only reducing screening efficiency but also causing poor device stability and rapid component wear due to vibration impact, making it difficult to meet the high-intensity demands of continuous industrial production. Fourth, insufficient device adaptability. The connection between the collection of screened feed and subsequent transportation is not smooth, increasing manual handling costs.

[0004] Therefore, a feed screening device for feed processing is proposed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1-5 As shown, the main body 1 of the device serves as the core carrier and screening medium of the entire feed screening device, providing a closed and orderly space for the graded screening of feed. Its internal structure enables multi-level graded filtration and directional discharge of feed.

[0021] The vibration component 2 is fixedly mounted on the lower end of the device body 1, which can drive the device body 1 to generate vibration, improve the efficiency of feed sliding and screening on the filter screen 104 and the inclined bottom plate 103, and prevent feed from clogging the filter screen or accumulating on the bottom plate surface.

[0022] There are four material blocking components 3, which are fixedly installed on the front and rear surfaces of the main body 1 at the corresponding discharge port positions. They can realize the on / off control of the discharge port, ensuring that feed of different specifications is graded and screened before being discharged uniformly or in batches, thus avoiding the mixing of feed of different specifications.

[0023] There are four collection hoppers 4, which are fixedly assembled on the front and rear surfaces of the main body 1 corresponding to the lower edge of the discharge port. They can receive feed of different specifications discharged from the discharge port. The lower end of the hopper can be connected to a conveying pipe or conveyor belt to realize the subsequent transfer and collection of the screened feed.

[0024] The support frame 5 is fixedly mounted on the lower end of the vibration component 2, providing a stable support for the entire feed screening device, ensuring the overall stability of the device during vibration screening, and preventing tipping or displacement.

[0025] The control box 6 is fixedly mounted on one side of the support frame 5 near the end. It is the core of the device's electrical control and can be electrically connected to the upper and lower vibrators 202 and the electric telescopic rod 301 at the same time. It can adjust the start and stop status and vibration parameters of the upper and lower vibrators 202, and control the extension and retraction of the electric telescopic rod 301, so as to achieve coordinated control of the screening rhythm and the timing of material discharge.

[0026] See appendix Figure 1-3 As shown, the outer shell 101 is the basic shell of the main body 1 of the device. It provides installation support for the feed hopper 102, inclined bottom plate 103, filter screen 104 and vibration component 2, and realizes the classified discharge of feed of different specifications through the opened discharge port. At the same time, the sliding groove on its inner wall provides guidance for the assembly and movement of the baffle component 3.

[0027] The feed hopper 102 is integrally formed with the feed inlet on the top surface of the device shell 101. It can buffer and guide the pelleted feed or feed raw materials to be screened, prevent the feed from spilling during feeding, and ensure that the feed can stably enter the screening area inside the main body 1 of the device.

[0028] The inclined base plate 103 is welded to the lower end of the inner shell 101 of the device and is inclined downward towards the discharge port. On the one hand, it can receive the fine debris that falls through the filter screen 104. On the other hand, the inclined structure enables the debris to slide down in a directional manner, ensuring that the debris can be discharged smoothly from the corresponding discharge port.

[0029] The filter screen 104 is welded in a Z-shape to the upper part of the device housing 101 and is inclined downwards towards the corresponding discharge port. The mesh size gradually increases from top to bottom, which can achieve multi-layer grading and screening of the feed entering the main body of the device 1. Large particles of feed will slide down to the corresponding discharge port in the area of ​​the upper low mesh filter screen 104, while small particles of feed can pass through the upper filter screen to the lower higher mesh filter screen for further screening, so as to achieve accurate grading of feed of different specifications.

[0030] See appendix Figure 1-3 As shown, the I-beam frame 201 is welded to the lower middle part of the inner part of the device housing 101, serving as the mounting carrier for the upper and lower vibrators 202. It can evenly transmit the vibration force of the upper and lower vibrators 202 to the device housing 101. At the same time, it is reinforced and welded to the inner wall of the device housing 101 by a triangular plate, thereby improving its structural stability and vibration force transmission efficiency.

[0031] The upper and lower vibrators 202 are welded to the center of the top surface of the I-beam 201 and electrically connected to the control box 6. They are the vibration power source of the entire device. The start and stop status and vibration parameters can be adjusted through the control box 6 to provide continuous and controllable vibration force for the screening operation of the main body 1 of the device.

[0032] The fixed piles 203 are evenly distributed and welded to the lower edge of the inner side of the device housing 101. They are reinforced and welded to the inner wall of the device housing 101 by a triangular plate, which not only provides a stable installation support for the spring telescopic rod 204, but also helps to transmit the vibration force of the vibration component 2.

[0033] The spring telescopic rods 204 are welded one-to-one to the bottom surface of each fixed pile 203 and the lower end is fixedly connected to the support frame 5. During the vibration of the device, they can play a buffering and amplifying role, which can not only prevent the device vibration from causing hard impact on the support frame 5, but also amplify the vibration amplitude of the main body 1 of the device, and further improve the screening effect.

[0034] See appendix Figure 1-4 As shown, the electric telescopic rod 301 is fixedly mounted on the side of the device housing 101 at both ends corresponding to the discharge port. As the power component of the baffle assembly 3, it can drive the sliding sleeve 302 to rise and fall through its own extension and retraction, thereby driving the baffle 303 to move.

[0035] The sliding sleeve 302 is welded to the upper end of the electric telescopic rod 301 and fixedly connected to the baffle 303, which can realize the stable transmission of power of the electric telescopic rod 301 and ensure that the baffle 303 moves smoothly along the sliding groove as the electric telescopic rod 301 extends and retracts.

[0036] The baffle 303 is slidably installed in the slide groove of the device housing 101 and is set in relation to the discharge port. By moving up and down along the slide groove, the discharge port can be closed and opened, thereby controlling the timing of the discharge of feed of the corresponding specification.

[0037] The operation procedure of this utility model is as follows: When starting the equipment, the operator first checks the connection status of each component of the device, confirms that the support frame 5 is stable, the collecting hopper 4 is in place and the lower end of the discharge port is connected to the conveying pipe or conveyor belt, and then turns on the power of the control box 6 on one side of the support frame 5. The vibration frequency and amplitude parameters of the upper and lower vibrators 202 are preset through the control box 6. At this time, the electric telescopic rod 301 is in the retracted state and the baffle 303 closes all discharge ports.

[0038] During the feeding and screening process, the pelleted feed or feed raw materials to be screened are poured into the gap in the feed hopper 102, which is integrally formed on the top surface of the device housing 101, or fed in via a conveying device. After being buffered and guided by the feed hopper 102, the feed enters the interior of the device body 1 and falls onto the top layer of the Z-shaped filter screen 104. At the same time, the control box 6 activates the upper and lower vibrators 202, which drive the I-beam frame 201 to vibrate. The device housing 101 vibrates accordingly, and the spring telescopic rod 204 on the bottom surface of the fixed pile 203 amplifies the vibration amplitude, thereby improving the screening efficiency. Under the action of vibration, the feed slides down the inclined filter screen 104. As the mesh size of the filter screen 104 gradually increases from top to bottom, large feed particles cannot penetrate the top layer of low mesh filter screen and slide down the top layer of filter screen to the corresponding discharge port for temporary storage. Medium feed particles penetrate the top layer of filter screen and are intercepted by the lower layer of higher mesh filter screen and slide down to the middle layer of the corresponding discharge port for temporary storage. Fine feed particles can penetrate all filter screens and fall onto the inclined bottom plate 103 at the lower end of the device housing 101.

[0039] During the sorting and discharging process, after different specifications of feed have been graded and temporarily stored at their respective discharge ports, a command is sent through the control box 6 to control the synchronous extension of the electric telescopic rods 301 at both ends of the corresponding discharge ports. The electric telescopic rods 301 drive the sliding sleeves 302 to rise, which in turn drives the baffles 303 to move upward along the sliding groove on the inner wall of the device housing 101, opening the discharge ports. Under the action of gravity, each specification of feed slides down from its corresponding discharge port into the collection hopper 4 below, and is then transported to subsequent processing or storage stages via the conveying pipe or conveyor belt at the lower end of the collection hopper 4. At the same time, fine debris on the inclined bottom plate 103 slides down the inclined surface of the bottom plate to the bottom discharge port and is collected by the corresponding collection hopper 4.

[0040] During repeated screening, after the different sizes of feed are discharged into the corresponding conveying pipes or conveyor belts, the first step of removing the starting equipment is repeated.

[0041] When the machine is shut down and finished, after all the feed in the feed hopper 102 has been screened and the feed transfer in each collection hopper 4 has been completed, the upper and lower vibrators 202 are turned off first through the control box 6, then the electric telescopic rod 301 is controlled to retract, driving the baffle 303 to move down and close all the discharge ports, and finally the power of the control box 6 is turned off to complete a single screening operation.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of protection of the present invention is defined by the appended claims and their equivalents.
