Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to an eccentric vibrating feed pellet screening device. Background Technology

[0002] Cattle and sheep need to be fed feed, and feed consists of particles of different sizes. Therefore, the feed needs to be sieved before feeding.

[0003] A search revealed a prior art vibrating screening device for feed production (publication number: CN104722483A), which includes a closed screen box with a screen fixed inside. The upper part of the screen box is provided with a material inlet, and the lower part is provided with a material outlet after screening. A funnel-shaped discharge pipe is connected to the material outlet at the lower part of the screen box, and the lower end of the discharge pipe is connected to a discharge port opened on the side wall of the material lifting cylinder. A vibration mechanism mainly composed of eccentric wheels is installed on the screen box or the discharge pipe.

[0004] Existing technologies mainly use the vibration of screens to screen feed. The screens are single and cannot be removed. However, in actual farming, the feed pellets fed to cattle and sheep need to be adjusted according to their growth stage. Small-sized cattle and sheep need to be fed smaller feed pellets. The difference in feed pellets removed by a single sorting method is difficult to adjust flexibly and has room for optimization.

[0005] Therefore, we propose an eccentric vibrating feed pellet screening device. Utility Model Content

[0006] The present invention mainly addresses the technical problem that the single-stage sorting method mentioned above is insufficient to meet practical needs, and provides an eccentric vibrating feed pellet screening device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an eccentric vibrating feed pellet screening device, comprising:

[0008] A base, on the top of which several elastic telescopic rods are fixedly installed, and a screening box is fixedly installed on the output shaft of the elastic telescopic rods. A vibration motor is fixedly installed on the bottom of the screening box.

[0009] A screening structure is set inside the cavity of a screening box for sorting materials. The screening structure includes a screen plate and a discharge port. Several discharge ports are opened on both sides of the screening box, and the screen plate is inserted into the discharge port.

[0010] A limiting component is installed on the inner wall of the screening box to block the discharge port and lock the screen plate.

[0011] In a preferred embodiment of this utility model, the screening box forms a box structure, the discharge port is a rectangular groove, the screen plate and the discharge port are used in conjunction, and the screen plate has screen holes at the position inside the screening box.

[0012] In a preferred embodiment of this utility model, the limiting component includes a baffle and a spring. The baffle is rotatably connected to the screening box, and the spring is fixedly connected to the screening box. The spring can abut against the baffle so that the baffle fits against the inner wall of the screening box and blocks the discharge port.

[0013] In a preferred embodiment of this utility model, the baffle is a rectangular plate with a size larger than the opening size of the discharge port, and the spring is an arc-shaped rod with one end fixedly connected to the inner wall of the screening box and the other end of the spring abutting against the baffle.

[0014] In a preferred embodiment of this utility model, the limiting component further includes an anti-detachment groove and a protrusion. The anti-detachment groove is provided on the top of the screen plate, and the protrusion is fixedly connected to the baffle. When the baffle is flipped to a horizontal position, the protrusion is engaged in the anti-detachment groove.

[0015] In a preferred embodiment of this utility model, the limiting component further includes bearing rods. Several bearing rods are fixedly installed on the opposite side walls of the screening box, and two bearing rods in symmetrical positions jointly support the screen plate and limit its movement.

[0016] This utility model provides an eccentric vibrating feed pellet screening device. It has the following beneficial effects:

[0017] 1. This eccentric vibrating feed pellet screening device is installed by inserting screen plates with different diameter screen holes into the discharge port and pushing the screen plates into the discharge port. Multiple screen plates distributed from top to bottom perform multi-stage screening of feed, selecting feed pellets of different sizes according to the different growth stages of cattle and sheep to facilitate feeding. It has stronger functionality and better practical effect.

[0018] 2. This eccentric vibrating feed pellet screening device features a flip-up baffle. A deformable spring abuts against the baffle, which is made of spring steel. The spring pushes the baffle so that it fits tightly against the side wall of the screening box, blocking the discharge port at the corresponding position. Therefore, the discharge port can be closed even when the screen plate is not installed. When the screen plate is installed, pushing the screen plate into the discharge port will push the baffle to flip, so the baffle will not interfere with the installation and removal of the screen plate.

[0019] 3. This eccentric vibrating feed pellet screening device uses a support rod to lift and limit the bottom of the screen plate, ensuring that the screen plate will not fall. When the screen plate is fully inserted into the discharge port, the baffle is located above the screen plate. The baffle's protrusion on one side engages with the anti-detachment groove to lock and limit the screen plate, preventing it from falling off during the vibration of the screening box. The stability of the screen plate after installation is ensured, while maintaining the convenience of disassembling and assembling the screen plate. Attached Figure Description

[0025] An eccentric vibrating feed pellet screening device, such as Figure 1 As shown, it includes:

[0026] A base 10 is provided, and several elastic telescopic rods 11 are fixedly installed on the top of the base 10. A screening box 12 is fixedly installed on the output shaft of the elastic telescopic rods 11. A vibration motor is fixedly installed on the bottom of the screening box 12. The bottom of the screening box 12 is provided with a window for material discharge. An eccentric block is fixedly installed on the output shaft of the vibration motor. By connecting the vibration motor to a control switch and a power supply, the screening box 12 as a whole generates an amplitude to achieve material screening.

[0027] like Figure 1 and Figure 2 As shown, a screening structure is set inside the cavity of the screening box 12 for sorting materials. The screening structure includes a screen plate 13 and a discharge port 14. Several discharge ports 14 are opened on both sides of the screening box 12. The screen plate 13 is inserted into the discharge port 14, and the screening box 12 forms a box structure. The discharge port 14 is a rectangular groove. The screen plate 13 and the discharge port 14 cooperate with each other. The screen plate 13 has screen holes at the position inside the screening box 12.

[0028] In this solution, the installation is completed by inserting screen plates 13 with different diameter screen holes into the discharge port 14 and pushing the screen plates 13 into the discharge port 14. Multiple screen plates 13 distributed from top to bottom perform multi-stage screening of feed, selecting feed particles of different sizes according to the different growth stages of cattle and sheep to facilitate feeding. It is more functional and has a better practical effect. The screen plates 13 extend through the discharge port to the outside of the screening box 12.

[0029] like Figure 3 and Figure 4 As shown, the limiting component is installed on the inner wall of the screening box 12 to block the discharge port 14 and lock the screen plate 13;

[0030] The limiting component includes a baffle 20 and a spring 21. The baffle 20 is rotatably connected to the screening box 12, and the spring 21 is fixedly connected to the screening box 12. The spring 21 can abut against the baffle 20 so that the baffle 20 fits against the inner wall of the screening box 12 and blocks the discharge port 14. The baffle 20 is a rectangular plate, and the size of the baffle 20 is larger than the opening size of the discharge port 14. The spring 21 is an arc-shaped rod. One end of the spring 21 is fixedly connected to the inner wall of the screening box 12, and the other end of the spring 21 abuts against the baffle 20.

[0031] In this design, considering that not all discharge ports 14 have screen plates 13 inserted inside, and the discharge ports 14 with screen plates 13 installed are in an open state, feed may spill from the discharge ports 14, a flip-up baffle 20 is provided. The baffle 20 is abutted by a deformable spring 21 made of spring steel. The spring 21 pushes the baffle 20 so that the baffle 20 is tightly attached to the side wall of the screening box 12 and blocks the corresponding discharge port 14. Therefore, the discharge port 14 can be closed even when the screen plate 13 is not installed. When the screen plate 13 is installed, the screen plate 13 is pushed into the discharge port 14 and pushes the baffle 20 to flip. Therefore, the baffle 20 will not interfere with the installation and removal of the screen plate 13.

[0032] like Figure 2 and Figure 4 As shown, the limiting component also includes an anti-detachment groove 22 and a protrusion 23. The anti-detachment groove 22 is opened on the top of the screen plate 13, and the protrusion 23 is fixedly connected to the baffle 20. When the baffle 20 is flipped to the horizontal position, the protrusion 23 is inserted into the anti-detachment groove 22. The limiting component also includes a bearing rod 24. Several bearing rods 24 are fixedly installed on the opposite side walls of the screening box 12. Two bearing rods 24 in symmetrical positions jointly support the screen plate 13 and limit its movement.

[0033] As a supplementary explanation to the above solution, the bottom of the screen plate 13 is supported and limited by the bearing rod 24 to ensure that the screen plate 13 will not fall. After the screen plate 13 is fully inserted into the discharge port 14, the baffle 20 is located above the screen plate 13. The protrusion 23 on one side of the baffle 20 is inserted into the anti-dislodgement groove 22 to lock and limit the screen plate 13, so as to prevent the screen plate 13 from falling off during the vibration of the screening box 12. The stability of the screen plate 13 after installation is guaranteed, and the convenience of disassembling and assembling the screen plate 13 is not lost.

[0034] The working principle of this utility model is as follows: Screen plates 13 with different diameter mesh sizes are inserted into the discharge port 14. Installation is completed by pushing the screen plates 13 into the discharge port 14. The spring 21 is made of spring steel. The spring 21 pushes the baffle 20, causing the baffle 20 to adhere tightly to the side wall of the screening box 12, thus blocking the corresponding discharge port 14. Therefore, the discharge port 14 can be closed even when the screen plates 13 are not installed. When installing the screen plates 13, pushing them into the discharge port 14 will cause the baffle 20 to flip, so the baffle 20 will not interfere with the installation and removal of the screen plates 13. This is achieved through the support rod 24. The bottom of the screen plate 13 is supported and limited to prevent it from falling. After the screen plate 13 is fully inserted into the discharge port 14, the baffle 20 is located above the screen plate 13. The protrusion 23 on one side of the baffle 20 is engaged in the anti-detachment groove 22 to lock and limit the screen plate 13, preventing the screen plate 13 from falling off during the vibration of the screening box 12. The bottom of the screening box 12 is provided with a window for discharge. An eccentric block is fixedly installed on the output shaft of the vibration motor. By connecting the vibration motor to the control switch and the power supply, the screening box 12 as a whole generates an amplitude to achieve multi-stage screening of materials.

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 illustrative of the principles of this utility model.
