Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a pellet grading and screening device for fermented feed for cattle and sheep based on rumination characteristics. Background Technology

[0002] In the cattle and sheep farming industry, feed quality and particle size grading directly affect the digestive and absorptive efficiency and growth performance of ruminants. Ruminants have a unique rumen structure, and the microbial community within their rumen has strict requirements on feed particle size. Overly large particles are difficult to chew and digest fully, easily leading to digestive diseases such as rumen impaction; while overly small particles accelerate rumen emptying, reducing the efficiency of feed fermentation and utilization in the rumen. Therefore, precise grading and screening of fermented feed particles is crucial, taking into account the physiological characteristics of ruminants such as cattle and sheep.

[0003] Currently, most feed pellet screening devices on the market use single-layer or multi-layer screen structures with a fixed inclination angle, and achieve pellet grading by driving the screen vibration with a vibrating motor. However, these devices often have the following problems when screening fermented feed pellets: fermented feed contains a certain amount of moisture and sticky substances, which easily leads to pellet sticking and screen hole blockage during screening, resulting in a decrease in screening efficiency. In addition, the screen plates of traditional devices are mostly fixed, and cleaning and replacement require disassembling a large number of parts, making the operation cumbersome.

[0004] To address the aforementioned issues, there is an urgent need to develop a cattle and sheep fermented feed pellet grading and screening device that can adapt to rumination characteristics, has an adjustable screening angle, easily replaceable screen plates, good anti-clogging effect, and stable operation, so as to improve feed grading accuracy and screening efficiency and meet the demand of modern cattle and sheep farming for high-quality feed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pellet grading and screening device for fermented feed for cattle and sheep based on rumination characteristics.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pellet grading and screening device for fermented feed for cattle and sheep based on rumination characteristics includes a housing. Multiple screening components are arranged inside the housing. Each screening component includes an outer frame, and a detachable screen plate is installed inside the outer frame. A hinge shaft is fixedly connected to one side of the outer frame and rotatably connected to the housing. At least two traction seats are fixedly connected to the other side of the outer frame. The traction seats of the multiple screening components are sequentially connected by traction cables. The top of the traction cables is fixedly connected to a crossbar. A hydraulic rod is installed between the crossbar and the top plate of the housing.

[0008] Furthermore, an opening is provided on one side of the housing, and the opening is correspondingly provided with the outer frame. A material inlet is provided on the outer frame, and an opening and closing plate is rotatably connected to the material inlet. The opening and closing plate is connected to the outer frame through a locking block.

[0009] Furthermore, the outer frame has a rectangular structure, and a folding plate is fixedly connected to the bottom of the outer frame. The area of ​​the lower opening of the folding plate is smaller than the area of ​​the outer frame.

[0010] Furthermore, the housing is provided with a feed pipe that extends into the housing and has a discharge port located above the screen plate. A conveying auger is installed inside the feed pipe and is driven by a feeding motor. A feeding port is provided at the top of the feed pipe and has a conical structure.

[0011] Furthermore, horizontal tracks are provided on the opposite side walls at the bottom of the outer frame, and brush rollers are provided between the horizontal tracks. The ends of the brush rollers are rotatably disposed within the horizontal tracks, and rotating rings are provided on the brush rollers. Counterweights are fixedly connected to the rotating rings.

[0012] Furthermore, a recycling tank is also provided inside the housing, and the recycling tank is located below the screening assembly.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention provides a grading and screening device for fermented feed pellets in cattle and sheep that adapts to rumination characteristics, features adjustable screening angles, easily replaceable screen plates, good anti-clogging effect, and stable operation. This improves feed grading accuracy and screening efficiency, meeting the demands of modern cattle and sheep farming for high-quality feed. One side of the outer frame is rotatably connected to the shell via a hinge shaft, while the other side is connected to a crossbar and hydraulic rod via a traction seat, traction cable, and hydraulic rod, forming a stable angle adjustment structure. The hydraulic rod's extension and retraction drive synchronously raises and lowers the crossbar, which in turn pulls multiple screening components around the hinge shaft via the traction cable, achieving flexible adjustment of the screening angle. This design optimizes the screening angle operation frequency according to the physical characteristics of the fermented feed. When the feed is highly viscous, the tilt angle can be increased to accelerate material flow and reduce adhesion and clogging; when higher grading accuracy is required, the tilt angle can be reduced to extend the material screening time, effectively improving the screening adaptability for different types of fermented feed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Reference Figures 1-4 A pellet grading and screening device for fermented feed for cattle and sheep based on rumination characteristics includes a shell, inside which multiple screening components 6 are arranged. Each screening component 6 includes an outer frame 10, and a detachable screen plate is arranged inside the outer frame 10. A hinge shaft 5 is fixedly connected to one side of the outer frame 10 and is rotatably connected to the shell. At least two sets of traction seats 13 are fixedly connected to the other side of the outer frame. The traction seats 13 of the multiple screening components 6 are connected in sequence by traction cables 4. The top of the traction cables 4 is fixedly connected to a crossbar, and a hydraulic rod is arranged between the crossbar and the top plate of the shell.

[0025] One side of the outer frame is rotatably connected to the shell via a hinge shaft 5, while the other side is connected to the crossbar and hydraulic rod via a traction seat 13 and a traction cable 4, forming a stable angle adjustment structure. The hydraulic rod's extension and retraction drive synchronously raises and lowers the crossbar, which in turn pulls multiple sets of screening components 6 around the hinge shaft 5 via the traction cable 4, achieving flexible adjustment of the screening angle. This design optimizes the screening angle operation frequency according to the physical characteristics of the fermented feed. When the feed is highly viscous, the tilt angle can be increased to accelerate material flow and reduce adhesion and blockage; when higher grading accuracy is required, the tilt angle can be reduced to extend the material screening time, effectively improving the screening adaptability of different types of fermented feed.

[0026] The screen plates are detachably installed within the outer frame, greatly simplifying the cleaning and replacement process compared to traditional fixed-installation screen plate structures. When screen plates become clogged or worn, operators can quickly remove the old screen plates for cleaning or replacement with new screen plates of different apertures without disassembling numerous related components. This not only saves maintenance time and labor costs but also allows for timely replacement of screen plates according to feed formulation adjustments, meeting diverse grading needs and improving the versatility of the device.

[0027] In other preferred embodiments, an opening is provided on one side of the housing, which corresponds to the outer frame. A material inlet is provided on the outer frame, and an opening and closing plate 11 is rotatably connected to the material inlet. The opening and closing plate 11 is connected to the outer frame through a locking block 12.

[0028] The shell opening is designed to correspond with the outer frame, providing a direct channel for operators to obtain the feed particles screened by each layer of screening components 6. The feeding port on the outer frame can be precisely connected to the particle discharge area after screening. When screening is completed or sampling is required, operators do not need to disassemble the device shell or screening components 6. They can simply reach the feeding port on the outer frame through the shell opening to quickly collect graded feed of different particle sizes.

[0029] In other preferred embodiments, the outer frame has a rectangular structure, and a gathering plate 9 is fixedly connected to the bottom of the outer frame. The lower opening area of ​​the gathering plate 9 is smaller than the area of ​​the outer frame. The smaller lower opening area of ​​the gathering plate 9 forms a "wider at the top and narrower at the bottom" gathering structure. When feed pellets are sieved through the screen plate, pellets that meet the particle size requirements will fall through the screen holes. The gathering plate 9 can guide the falling pellets, converging the scattered pellets to the lower opening and preventing them from scattering in all directions.

[0030] In other preferred embodiments, a feed pipe 2 is provided on the shell, extending into the shell and having a discharge port 3 located above the screen plate. A conveying auger is installed inside the feed pipe 2, driven by a feeding motor 1. A feeding port with a conical structure is located at the top of the feed pipe 2. Driven by the feeding motor 1, the conveying auger inside the feed pipe 2 rotates continuously, evenly conveying the feed particles entering through the feeding port to the discharge port 3 inside the shell. Compared to the traditional free-fall feeding method, the conveying auger can precisely control the feed amount by adjusting the speed of the feeding motor 1, avoiding excessive instantaneous feeding due to feed accumulation and preventing localized overload of the screen plate from affecting the screening effect. Simultaneously, the uniform feeding speed ensures that the feed particles are evenly distributed on the screen plate, allowing each part of the screen plate to fully perform its screening function.

[0031] In other preferred embodiments, horizontal tracks are provided on the opposite side walls at the bottom of the outer frame, and a brush roller 7 is provided between the horizontal tracks. The end of the brush roller 7 is rotatably disposed within the horizontal track, and a rotating ring is provided on the brush roller 7. A counterweight 8 is fixedly connected to the rotating ring.

[0032] The brush roller 7 is in close contact with the bottom of the screen plate. When the device is running, the tilt of the screen plate will drive the brush roller 7 to move back and forth in the horizontal track. The bristles on the surface of the brush roller 7 can continuously clean the screen holes on the bottom surface of the screen plate. For particles in fermented feed that are easy to stick to the screen holes, the brush roller 7 can remove them in time, avoiding the problem of reduced screening efficiency caused by screen hole blockage.

[0033] In other preferred embodiments, a recycling tank is also provided inside the housing, and the recycling tank is located below the screening component 6.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
