Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and more specifically, to a rabbit feed impurity removal sieve. Background Technology

[0002] In the large-scale production of rabbit feed, the effectiveness of impurity separation in the raw material pretreatment process directly affects the quality of the finished product and the safety of breeding.

[0003] Existing patent publication number CN222490900U discloses an intelligent impurity removal device for laboratory rabbit feed, relating to the field of laboratory rabbit feed impurity removal equipment. It includes a support frame, with a screening mechanism fixedly connected to the top of the support frame. By setting up a sorting component, it achieves the effect of color screening of pelleted feed, thereby screening out black pellets, reddish pellets, and pellets with uneven color. By setting up the screening component, a first driving mechanism, and a second driving mechanism, it achieves the effect of screening the size of the pelleted feed. The drum screen can remove irregular pellets, powder, and impurities from the pelleted feed, thereby ensuring the uniformity of the pelleted feed. The inventors discovered the following problems with the existing technology during the development of this utility model: Traditional single-stage vibrating screens can only classify particles by size, and lack specific means to separate impurities such as metal fragments (such as iron nails and iron wires) and dense stones mixed in the raw materials. Although some equipment is equipped with metal detection devices, secondary processing is required after screening, which leads to a longer process flow and increased production costs.

[0004] Therefore, a rabbit feed impurity removal sieve is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rabbit feed impurity removal sieve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rabbit feed impurity removal sieve, comprising a supporting table, a bearing frame fixedly installed above the supporting table, a motor detachable at the left end of the upper surface of the supporting table, a rotating shaft connected to the output end of the motor, an active flywheel detachably installed at the end of the rotating shaft away from the motor, a positioning block installed parallel to the upper surface of the bearing frame, a rotating rod movably installed inside the positioning block, a fixing frame fixedly installed at the right end of the upper surface of the supporting table, a sliding rod horizontally fixedly installed at the middle position of the fixing frame and the bearing frame, an upper sieve plate movably installed above the sliding rod, and a lower sieve plate fixedly installed at the bottom of the upper sieve plate.

[0007] Preferably, a driven flywheel is detachably mounted on the outer side of the rotating rod, the driven flywheel is positioned directly above the driving flywheel, and an annular belt is fitted around the outer sides of both the driving flywheel and the driven flywheel.

[0008] Preferably, a circular rotating disk is fitted onto one end of the rotating rod near the fixed frame, and a positioning rod is vertically welded onto the side of the rotating disk away from the rotating rod. A slidable telescopic rod is fitted onto the outer side of the positioning rod via a linear bearing, and the end of the telescopic rod away from the positioning rod is fixedly connected to the middle right side of the upper screen plate by bolts.

[0009] Preferably, the upper side of the slide bar is machined with a groove along the axial direction, and a slider is slidably installed inside the groove. The top of the slider is rigidly connected to the bottom of the upper screen plate by an internal hex bolt.

[0010] Preferably, the bottom of the upper screen plate is fixedly installed with a fixing rod by welding, and the bottom of the fixing rod is rigidly connected to the reinforcing plate on the upper surface of the lower screen plate by bolts. The upper surface of the lower screen plate has a steel insert with a threaded hole corresponding to the position of the fixing rod.

[0011] Preferably, a baffle plate is fixedly installed at the bottom of the upper screen plate by welding, and the installation position of the baffle plate corresponds to the center area directly above the lower screen plate.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this rabbit feed impurity removal screener adopts a dual-stage screen plate linkage design. While the upper screen plate completes coarse screening, the lower screen plate is driven to vibrate synchronously through a rigidly connected fixed rod, so that the material completes two particle size classifications in a single process, which improves the efficiency compared with traditional single-stage screening.

[0013] Compared with existing technologies, this rabbit feed impurity removal screener uses an integrated metal separation system to precisely match the vibration frequency of the screen plate with the working rhythm of the magnetic suction component through the mechanical linkage of the rotating disk and the telescopic rod. The neodymium iron boron permanent magnet array embedded on the surface of the lower screen plate can capture magnetic impurities such as iron filings in real time. Combined with the concentrated adsorption zone formed by the baffle plate, the metal separation rate is increased. Attached Figure Description

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.

[0019] Example 1 As attached Figures 1 to 3 The rabbit feed impurity removal sieve shown includes a support table 1, a support frame 2 fixedly installed above the support table 1, a motor 3 detachable at the left end of the upper surface of the support table 1, a rotating shaft 4 connected to the output end of the motor 3, an active flywheel 5 detachably installed at the end of the rotating shaft 4 away from the motor 3, a positioning block 6 installed parallel to the upper surface of the support frame 2, a rotating rod 7 movably installed inside the positioning block 6, a fixing frame 13 fixedly installed at the right end of the upper surface of the support table 1, a sliding rod 14 horizontally fixedly installed at the middle position between the fixing frame 13 and the support frame 2, an upper screen plate 17 movably installed above the sliding rod 14, and a lower screen plate 19 fixedly installed at the bottom of the upper screen plate 17.

[0020] Specifically: First, the combination design of detachable motor 3 and active flywheel 5 facilitates quick replacement of transmission components according to different particle size requirements, thereby improving screening efficiency; second, the cooperation between positioning block 6 and rotating rod 7 ensures stable control of vibration amplitude; third, the upper screen plate 17 and lower screen plate 19 are installed at a fixed interval, enabling simultaneous screening of two particle sizes; fourth, the support system composed of slide rod 14 and bearing frame 2 reduces equipment vibration noise and ensures stable operation; fifth, the modular design shortens the disassembly and assembly time of each component and reduces maintenance costs.

[0021] Example 2 Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 3 As shown below, see details: In a preferred embodiment, a driven flywheel 8 is detachably mounted on the outer side of the rotating rod 7. The driven flywheel 8 is made of high-precision cast iron and its surface has undergone dynamic balancing treatment to ensure smooth operation. The driven flywheel 8 is positioned directly above the driving flywheel 5 to ensure uniform tension of the belt 9. The outer sides of the driving flywheel 5 and the driven flywheel 8 are jointly fitted with an annular belt 9. The belt 9 is made of high-strength neoprene rubber and has anti-slip texture on its surface to effectively prevent slippage during operation. The tension of the belt 9 can be finely adjusted by adjusting the installation position of the motor 3 to ensure optimal transmission efficiency.

[0022] In a preferred embodiment, a circular rotating disk 10 is fitted onto one end of the rotating rod 7 near the fixed frame 13. The rotating disk 10 is made of high-strength aluminum alloy and its surface is anodized to enhance wear resistance. A positioning rod 11 is vertically welded to the side of the rotating disk 10 away from the rotating rod 7. The diameter of the positioning rod 11 is precisely calculated to ensure its fit with the telescopic rod 12. A slidable telescopic rod 12 is fitted onto the outer side of the positioning rod 11 via a linear bearing. The telescopic rod 12 is made of hollow steel pipe and has an internal lubricating oil groove to reduce friction. The end of the telescopic rod 12 away from the positioning rod 11 is fixedly connected to the middle right side of the upper screen plate 17 by bolts. A rubber shock-absorbing pad is provided at the connection to reduce impact force.

[0023] In a preferred embodiment, a groove 15 is machined along the axial direction on the upper side of the slide bar 14. A slider 16 is slidably installed inside the groove 15. Carbon steel wear-resistant guide bars are provided on both sides of the slider 16. The gap between the guide bars and the side wall of the groove 15 is controlled within the range of 0.2-0.3mm. The top of the slider 16 is rigidly connected to the bottom of the upper screen plate 17 by an internal hex bolt. A spring washer is added at the connection to prevent loosening. When the equipment is running, the slider 16 makes reciprocating linear motion in the groove 15. The deviation of its motion trajectory does not exceed ±0.5mm, effectively ensuring the stability of the screening process.

[0024] In a preferred embodiment, a fixing rod 18 is fixedly installed at the bottom of the upper screen plate 17 by welding. The fixing rod 18 is made of stainless steel round tube and the surface is polished to reduce material adhesion. The bottom of the fixing rod 18 is rigidly connected to the reinforcing plate on the upper surface of the lower screen plate 19 by bolts. Rubber shock-absorbing washers are added at the connection to reduce vibration transmission. The upper surface of the lower screen plate 19 has steel inserts with threaded holes corresponding to the positions of the fixing rods 18 to ensure that the connection strength meets the design requirements. When the equipment is running, the fixing rod 18 can effectively transmit vibration force and maintain the relative position accuracy between the two screen plates, and the deviation is controlled.

[0025] In a preferred embodiment, a baffle plate 20 is fixedly installed at the bottom of the upper screen plate 17 by welding. The baffle plate 20 is made of stainless steel sheet by stamping and the surface is brushed to enhance wear resistance. The installation position of the baffle plate 20 corresponds to the center area directly above the lower screen plate 19. The baffle plate 20 can effectively prevent material accumulation and guide large particles that have not passed through the upper screen to fall into the screening area of ​​the lower screen plate 19, ensuring the orderly transfer of materials between the two screen plates and avoiding material splashing during the screening process.

[0026] In this embodiment, the supporting table 1 and the support frame 2 are both commercially available metric equipment that can be directly purchased by those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them and have not made any structural or functional improvements. We will not go into details here.

[0027] The working process of this utility model is as follows: When in use, firstly, after the motor 3 is started, the active flywheel 5 is driven to rotate through the rotating shaft 4. The active flywheel 5 drives the driven flywheel 8 outside the rotating rod 7, which is positioned in the positioning block 6 above the support frame 2, to rotate synchronously through the annular belt 9, so that the rotating rod 7 generates rotational motion. The circular rotating disk 10 sleeved on the right end of the rotating rod 7 rotates accordingly. The positioning rod 11 vertically welded on it drives the telescopic rod 12 connected by the linear bearing to perform reciprocating linear motion. The telescopic rod 12 is rigidly connected to the middle right side of the upper screen plate 17 through bolts, driving the upper screen plate 17 to perform horizontal reciprocating vibration along the sliding groove 15 on the sliding rod 14 through the bottom slider 16. When the upper screen plate 17 vibrates, its bottom is driven by the welded fixing rod 18 to drive the lower screen plate 19 to vibrate synchronously. The lower screen plate 19 is bolted to the fixing rod 18 through steel inserts to ensure structural stability. After the material is fed in, it first passes through the upper screen plate 17 for coarse screening. Fine particles fall through the screen to the lower screen plate 19 for secondary fine screening. During this process, the baffle plate 20 welded to the bottom of the upper screen plate 17 concentrates and guides the material to the central area of ​​the lower screen plate 19. With the help of the magnetic suction components embedded on the surface of the lower screen plate 19, the metal impurities and the particle size classification materials are separated synchronously. The entire screening system is driven by a single motor 3, and the power is distributed through the flywheel-belt transmission mechanism 9, which finally completes the classification screening and impurity removal of the material.

[0028] The above describes the working principle of this rabbit feed impurity removal screen.
