[0042] As shown in the drawings, the preferred embodiment of the screening and collecting device is provided. Figures 1-3

[0043] As shown in the drawings, the screening and collecting device of the utility model is used for screening feed, and the screening and collecting device comprises a base 100, a screening hopper 300 and a vibration motor 400. The base 100 is provided with a discharging channel, and the base 100 has a plurality of connecting components 200.

The vibration motor 400 is connected with the outer peripheral wall of the screening hopper 300. The inner cavity of the screening hopper 300 is provided with a scattering disc 310 and a screen 320. The outer peripheral wall of the scattering disc 310 is spaced apart from the inner cavity wall of the screening hopper 300, and a discharging channel is formed therebetween. The screen 320 is located below the scattering disc 310, and the outer peripheral wall of the screen 320 is connected with the inner cavity wall of the screening hopper 300. Figure 1 The screening and collecting device of the utility model is used for screening feed, and the design realizes the efficient feed screening and collecting function through the cooperative work of the base 100, the screening hopper 300 and the vibration motor 400. The mounting mode of the product is hoisting, and the base 100 is hoisted and mounted on the corresponding carrier (such as a steel structure frame), and receives the raw materials conveyed by other process equipment (such as feed mixing equipment) of the feed production line.

[0044] As shown in the drawings, the preferred embodiment of the screening and collecting device is provided.

[0045] Figure 3 ​​As shown, in specific implementation, the base 100 is a hollow tubular structure, and a cover plate is bolted to the upper end of the base 100, and the cover plate is provided with a feeding port. The base 100 is designed as a hollow tubular structure, and a vertical feeding channel is formed inside the base 100, so that the internal space of the base 100 is fully utilized, and a direct feeding channel is provided for the feed raw materials. The bolted cover plate can ensure the sealing of the top of the base 100, and the feeding port is the entrance for the feed raw materials to enter the screening and collecting device, and its position and size can be adjusted according to actual needs to adapt to the input of feed raw materials with different flow rates. The bolted cover plate is convenient to disassemble and install, and facilitates the cleaning and maintenance of the entire screening and collecting device.

[0046] In a preferred implementation, as shown in the drawings, Figure 3 The inner cavity of the base 100 is provided with a discharging disc 110, and the discharging disc 110 is a funnel-shaped structure, and the bottom through hole of the discharging disc 110 is opposite to the bulk disc 310.

[0047] In specific implementation, the discharging disc 110 is made of stainless steel material, and the funnel-shaped discharging disc 110 can effectively guide the falling path of the feed raw materials, so that the feed raw materials fall along the funnel inclined wall of the discharging disc 110 under the action of gravity and fall through the bottom through hole, which can reduce the accumulation of feed during the discharging process. The bottom through hole of the discharging disc 110 is opposite to the bulk disc 310, so that the feed can accurately fall on the bulk disc 310. The bulk disc 310 serves to further disperse the feed, so that it is uniformly distributed on the screen 320, thereby improving the screening efficiency. This design can effectively solve the problem of feed accumulation in the middle of the screen 320.

[0048] In this embodiment, the screening hopper 300 is the core component of the screening feed, and the bulk disc 310 and the screen 320 are arranged inside the screening hopper 300. The outer peripheral wall of the bulk disc 310 is spaced apart from the inner cavity wall of the screening hopper 300 to form a discharging channel for dispersing the feed and uniformly falling on the screen 320. The screen 320 is located below the bulk disc 310, and the outer peripheral wall of the screen 320 is tightly connected with the inner cavity wall of the screening hopper 300 for screening the feed. The screening hopper 300 is the main part of the screening device, and the internal structure includes the bulk disc 310 and the screen 320. The outer peripheral wall of the bulk disc 310 is spaced apart from the inner cavity wall of the screening hopper 300 to form an annular discharging channel. This design allows the feed to be distributed and fallen along the discharging channel after entering the screening hopper 300, avoiding concentrated accumulation. The screen 320 is located below the bulk disc 310, and the outer peripheral wall of the screen 320 is tightly connected with the inner cavity wall of the screening hopper 300 to form a complete screening surface. The screen 320 is designed according to the particle size requirements of the feed, and is used to screen the feed particles meeting the requirements. The material of the screen 320 is usually stainless steel or other wear-resistant materials to ensure its durability and screening efficiency.

[0049] On the other hand, it can be understood that the vibration motor 400 is connected to the outer peripheral wall of the screening hopper 300, and the feed is shaken in the screening hopper 300 by the vibration effect, so as to accelerate the screening process of the feed through the screen 320, and more meet the processing needs of the powder feed. The frequency and amplitude of the vibration motor 400 can be adjusted according to the characteristics of the feed to achieve the best screening effect.

[0050] In a specific implementation, the screening hopper 300 is a conical hopper made of stainless steel, and the top of the screening hopper 300 is open and connected to the bottom of the base 100.

[0051] In a specific implementation, the bulk tray 310 is a conical hopper with a smooth outer surface, and the conical top of the bulk tray 310 is arranged towards the base 100. The screen 320 is in the shape of a conical hopper, and the conical top of the screen 320 is arranged in the opposite direction to the conical top of the bulk tray 310.

[0052] The bulk tray 310 is a conical hopper with a smooth outer surface, and the conical top is arranged towards the base 100. Under the action of gravity, the feed raw materials fall from the bulk tray 310 to the outer wall of the bulk tray 310, and are dispersed along the smooth outer surface. The conical structure of the bulk tray 310 can effectively guide the distribution of the feed, so that it slides down along the slope under the action of gravity and finally falls on the screen 320.

[0053] The conical structures of the bulk tray 310 and the screen 320 cooperate with each other to form an efficient screening system. The smooth outer surface and the conical structure of the bulk tray 310 can distribute the feed raw materials to the screen 320, and the conical structure of the screen 320 can guide the feed raw materials to pass through the screen hole quickly, which can effectively improve the screening efficiency.

[0054] In a specific implementation, regarding the installation method of the bulk tray 310, a horizontal rod is welded in the inner cavity of the conical hopper, and the bulk tray 310 is installed on the horizontal rod; the upper surface of the horizontal rod is provided with a chamfer structure. The horizontal rod is welded in the inner cavity of the conical hopper of the bulk tray 310 for supporting and welding the bulk tray 310. This welding method can ensure that the bulk tray 310 remains stable during the vibration screening process, while avoiding loosening caused by frequent vibration. The upper surface of the horizontal rod is designed with a chamfer structure, which is to avoid the accumulation of powder on the horizontal rod.

[0055] As shown in FIG. 4, in a specific implementation, in order to meet the implementation of the vibration motor 400, the connecting component 200 includes: Figure 2 A stud 210, the outer peripheral wall of the base 100 has a first flange plate, the outer peripheral wall of the screening hopper 300 has a second flange plate, and the stud 210 penetrates the first flange plate and the second flange plate;

[0056]

[0057] ​The first rubber spring 220 is sleeved on the stud 210 and arranged on the upper surface of the first flange plate.

[0058] The second rubber spring 230 is sleeved on the stud 210 and arranged on the lower surface of the second flange plate.

[0059] The stud 210 is threadedly connected with a plurality of nuts, the first rubber spring 220 and the first flange plate are locked by the nuts, and the second rubber spring 230 and the second flange plate are locked by the nuts.

[0060] In specific implementation, in order to meet the operation requirements of the vibration motor 400 and ensure the stability and reliability of the screening device, the design of the connecting component 200 adopts a combined structure of the flange plate, the stud 210, the rubber spring and the nut. This design not only effectively fixes the screening hopper 300, but also buffers the vibration through the rubber spring, reducing the wear and noise of the equipment.

[0061] Specifically, the first rubber spring 220 is sleeved on the stud 210 and located on the upper surface of the first flange plate. Its role is to buffer the high-frequency vibration generated by the vibration motor 400, reduce the direct impact of the vibration on the base 100 and the screening hopper 300, and thus prolong the service life of the equipment. The second rubber spring 230 is sleeved on the stud 210 and located on the lower surface of the second flange plate. It cooperates with the first rubber spring 220 to further buffer the vibration and reduce the transmission of the vibration to the inside of the screening hopper 300, ensuring the stability of the screening process.

[0062] It should be noted that the outer peripheral wall of the base 100 is provided with the first flange plate, and the outer peripheral wall of the screening hopper 300 is provided with the second flange plate. The stud 210 penetrates the first flange plate and the second flange plate and is used to fix the screening hopper 300 on the base 100. This flange plate connection mode can provide stable support and is convenient for installation and disassembly. The stud 210 is threadedly connected with a plurality of nuts, the first rubber spring 220 and the first flange plate are locked by the nuts, and the second rubber spring 230 and the second flange plate are locked by the nuts. This design can ensure the firmness of the connection, and through the elastic deformation of the rubber spring, the vibration energy can be absorbed, reducing the noise and vibration of the equipment. The rubber spring has good elasticity and damping characteristics and can effectively absorb vibration energy. When the vibration motor 400 works, the generated vibration is transmitted to the rubber spring through the stud 210, and the rubber spring buffers the vibration through elastic deformation, reducing the direct impact of the vibration on the equipment.

The corrugated rubber sleeve 500 is a flexible and elastic rubber pipeline, which is widely used in occasions requiring flexible connection and buffering vibration. In the screening and collecting device, the main function of the corrugated rubber sleeve 500 is to connect the base 100 and the conical hopper, provide flexible connection, reduce the direct impact of vibration on the equipment, especially the base 100, and isolate the base 100 from the vibration motor 400. The corrugated rubber sleeve 500 can effectively seal the connection part to prevent feed leakage and keep the inside of the equipment clean.

[0064] In the preferred implementation, the screening and collecting device further comprises a screw conveyor 600, the feeding end of the screw conveyor 600 is connected with the bottom of the conical hopper. The screening and collecting device introduces the screw conveyor 600, the feeding end of which is connected with the bottom of the conical hopper, realizing the integrated design of screening and conveying.
