Description

Technical Field

[0001] This application relates to the technical field of feed processing, and in particular to a feed ingredient crushing device. Background Technology

[0002] Crushing and screening feed ingredients is a core part of feed processing. Its efficiency directly affects the particle uniformity, nutrient absorption rate, and production cost of the finished feed. During the crushing process, it is common to produce substandard broken feed. Different feed ingredients have different physical properties. Raw materials that are too hard or too tough are prone to forming irregular fragments or coarse particles that are not fully crushed during crushing. These require manual screening and re-feeding for crushing, which reduces production efficiency.

[0003] Therefore, those skilled in the art have provided a feed ingredient grinding device to solve the problems mentioned in the background art. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a feed raw material crushing device.

[0005] The feed ingredient grinding equipment provided in this application adopts the following technical solution:

[0006] A feed ingredient crushing device includes a mounting frame, a housing fixedly connected to the mounting frame, a discharge pipe extending through the bottom end of the housing, a crusher centrally mounted inside the mounting frame, a feed hood mounted at the upper feed inlet of the crusher, a feed pipe mounted at the front end of the feed hood, a screening component mounted inside the housing and outside the crusher, and a cleaning component mounted on the upper part of the inner side of the housing.

[0007] Preferably, the screening assembly includes a screening tube, which is rotatably connected to the housing. A toothed ring is fixedly connected to the rear end of the screening tube. A gear is meshed with the outer side of the toothed ring near the upper center. A motor is installed at the rear end of the gear. The motor housing is fixedly connected to the housing. Several screening holes are opened on the side wall of the screening tube. Several annularly arranged transfer plates are fixedly connected to the inner side of the screening tube.

[0008] Preferably, the cleaning assembly includes a wire roller, a rotating rod fixedly connected to the inner side of the wire roller, mounting blocks rotatably connected to both ends of the rotating rod, a mounting shell movably connected to the outer side of the mounting blocks, a movable plate fixedly connected to the upper end of the mounting blocks, a limit groove formed on the inner side of the mounting shell, the movable plate installed in the limit groove, a spring installed between the upper end of the movable plate and the mounting shell, and the mounting shell fixedly connected to the housing.

[0009] Preferably, the transfer plate is inclined, tilted towards the rotation direction of the screening tube, and the surface of the transfer plate near the screening tube is arc-shaped.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. The motor, in conjunction with gears and a gear ring, drives the screening tube to rotate. The screening tube screens the raw material through screening holes. Unpassed material falls from the top into the feed hood under the action of the transfer plate, and then enters the crusher for secondary crushing. A spring, in conjunction with a moving plate and mounting block, drives the wire roller to contact the outer wall of the screening tube. As the screening tube rotates, the wire roller rotates via a rotating rod, and the steel wire on the wire roller inserts into the screening holes to clear any stuck material. This system allows for screening and repeated crushing of crushed material, and also clears any material stuck during screening. Attached Figure Description

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.

[0018] Example 1

[0019] like Figure 1-2As shown, this application discloses a feed raw material crushing equipment, including a mounting frame 1, a housing 2 fixedly connected to the mounting frame 1, a discharge pipe 3 installed at the bottom end of the housing 2, a crusher 8 installed in the center inside the mounting frame 1, a feed hood 9 installed at the upper feed inlet of the crusher 8, a feed pipe 10 installed at the front end of the feed hood 9, a screening component installed on the inner side of the housing 2 and located outside the crusher 8, and a cleaning component installed on the upper part of the inner side of the housing 2.

[0020] Feed enters the feed hood 9 through the feed pipe 10, and then enters the crusher 8 through the feed hood 9 for crushing. The crushed feed is then screened by the screening component, and the screened feed is discharged through the discharge pipe 3. The cleaning component cleans the screening component.

[0021] like Figure 2-3 As shown, the screening assembly includes a screening tube 4, which is rotatably connected to the housing 2. A toothed ring 5 is installed at the rear end of the screening tube 4, and a gear 6 is installed at the upper center of the outer side of the toothed ring 5. A motor 7 is installed at the rear end of the gear 6, and the housing of the motor 7 is fixedly connected to the housing 2. Several screening holes 12 are opened on the side wall of the screening tube 4, and several annularly arranged transfer plates 11 are installed on the inner side of the screening tube 4. The motor 7 drives the gear 6 to rotate, and the gear 6, in conjunction with the toothed ring 5, drives the screening tube 4 to rotate. The feed crushed by the crusher 8 falls onto the screening tube 4 and is screened through the screening holes 12 on the screening tube 4. By setting the transfer plates 11, the feed that has not been screened through the screening holes 12 can be moved to the upper end of the feed hood 9 and fall down for further crushing.

[0022] like Figure 2 , 4 As shown, the cleaning assembly includes a wire roller 13, a rotating rod 16 installed on the inner side of the wire roller 13, mounting blocks 15 installed at both ends of the rotating rod 16, a mounting shell 14 installed on the outer side of the mounting blocks 15, a movable plate 17 installed on the upper end of the mounting blocks 15, a limiting groove 18 opened on the inner side of the mounting shell 14, the movable plate 17 installed in the limiting groove 18, a spring 19 installed between the upper end of the movable plate 17 and the mounting shell 14, the mounting shell 14 being fixedly connected to the housing 2, the spring 19 pressing the movable plate 17 causing the wire roller 13 installed between the two mounting blocks 15 via the rotating rod 16 to contact the screening tube 4, the wire on the wire roller 13 passing through the screening hole 12 to clean the feed stuck in the screening hole 12, the movable plate 17 cooperating with the limiting groove 18 to limit the movement direction of the wire roller 13.

[0023] like Figure 2-3 As shown, the transfer plate 11 is inclined and tilted towards the rotation direction of the screening tube 4. The surface of the transfer plate 11 near the screening tube 4 is arc-shaped. The arc surface between the transfer plate 11 and the screening tube 4 can reduce the dead corner of feed residue.

[0024] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] The implementation principle of a feed ingredient grinding device in this application is as follows:

[0027] During use, feed ingredients enter the feed hood 9 through the feed pipe 10 and fall evenly into the crushing chamber of the crusher 8. The high-speed rotating blades inside the crusher 8 impact, shear, and grind the ingredients, initially crushing them into mixed particles. The crushed particles fall downwards due to gravity and enter the screening area of ​​the screening pipe 4. The motor 7 drives the gear 6 to mesh with the gear ring 5, causing the screening pipe 4 to rotate at a uniform speed. The screening holes 12 on the side wall of the screening pipe 4 allow particles that meet the particle size requirements to pass through and fall to the bottom of the shell 2, where they are discharged through the discharge pipe 3. Coarse particles that do not pass through the screening holes 12 are discharged. The particles are captured by the conveying plates 11 arranged in a ring on the inner side of the screening tube 4. The conveying plates 11 are designed with an inclined arc structure, and their inclination direction is consistent with the rotation direction of the screening tube. The coarse particles are moved along the inner wall of the screening tube to the top of the feed hood 9 and fall back into the crusher 8 for secondary crushing, forming a closed loop. The spring 19 of the cleaning component continuously applies pressure, pushing the moving plate 17 to move down along the limiting groove 18, so that the wire roller 13 is tightly attached to the outer wall of the screening tube 4. When the screening tube 4 rotates, the wire on the wire roller 13 inserts into the screening hole 12 to scrape off the stuck feed particles and prevent blockage.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
