Description

Technical Field

[0001] This utility model relates to a forage screening device, specifically a forage screening device for beef cattle breeding, belonging to the field of forage screening technology for beef cattle breeding. Background Technology

[0002] In the process of livestock farming, beef cattle need to be fed hay. When the pasture is harvested, there is a lot of dust on the surface. If the mud mixed in the hay is not cleaned, the beef cattle will eat too much mud, which will be very harmful to their health. The mud enters the cow's stomach and affects the cow's digestion and absorption, which can lead to forestomach atony and diarrhea. Therefore, a dust screening device is needed to screen out the dust in the hay.

[0003] The existing patent authorization announcement number CN221869156U discloses a dust screening device for beef cattle feed. Through a set "V"-shaped screening cylinder, a servo motor drives the second auger to rotate. The second auger drives the first auger to rotate through a universal coupling. It can move the feed from the left end to the right end of the screening cylinder and discharge it through the discharge port. The first filter screen and the lower discharge trough can filter sand and gravel, which are collected by the collection box. The second filter screen, the upper discharge trough and the dust collector can collect the airborne dust.

[0004] In the aforementioned patent, a first filter screen located at the bottom of the screening cylinder filters sand and gravel that meet the filtration conditions, and a collection box collects them. However, larger sand and gravel particles are blocked on the first filter screen and easily get stuck in the holes of the first filter screen, making subsequent manual cleaning more troublesome and increasing labor intensity. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this utility model is to provide a forage screening device for beef cattle breeding in order to solve the above-mentioned problems. In this way, the larger sand and gravel particles are blocked on the first filter screen and easily get stuck in the holes of the first filter screen, which makes subsequent manual cleaning troublesome and increases labor intensity.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: a forage screening device for beef cattle breeding, including a collection box, a tilting assembly on the top of the collection box, and a screening assembly inside the tilting assembly; the screening assembly includes a middle cylinder and a feed cylinder and a discharge cylinder disposed at the left and right ends of the middle cylinder, a filter screen one and a filter screen two extending into the feed cylinder and the discharge cylinder are fixedly installed inside the middle cylinder, the filter screen one is located at the lower part of the middle cylinder, and the filter screen two is located at the upper part of the middle cylinder, and a waste discharge port and a discharge port are fixedly connected to the outer wall of the end of the discharge cylinder away from the middle cylinder; the tilting assembly The component includes a support frame fixedly installed on the top of the collection box. The intermediate cylinder is rotatably connected to the inside of the support frame. A feed cylinder is fixedly installed on the outside of the intermediate cylinder. A horizontal plate is fixedly installed on the top of the support frame. A servo motor is fixedly installed on the top of the horizontal plate. A gear two that meshes with gear one is fixedly installed on the outside of the output shaft of the servo motor. The servo motor model can be MSMD012G1U. The servo motor drives gear two to rotate, and gear two drives gear one that meshes with it to rotate, thereby causing the intermediate cylinder to flip inside the support frame, so that the screening component is inverted as a whole, which facilitates the rolling and discharge of larger impurities to both ends.

[0007] Preferably, two conveying augers are rotatably installed inside the feed cylinder and discharge cylinder. The ends of the two conveying augers that are close to each other are connected by a universal joint. A drive motor connected to the conveying auger inside the discharge cylinder is fixedly installed at the end of the discharge cylinder away from the intermediate cylinder. The drive motor model can be Y2-132M-4. After the drive motor is started, it can drive the conveying auger connected to it to rotate. Since the two conveying augers are connected by a universal joint, the two conveying augers can rotate synchronously, conveying the grass entering the feed cylinder towards the discharge cylinder. During the conveying process, the grass is screened by filter screen one and filter screen two to remove sand and dust. Under the action of the conveying augers, separation and conveying are achieved.

[0008] Preferably, the collection box includes a box body with a pull-out opening on the front side. A drawer is movably installed inside the pull-out opening. A discharge port is provided on the top of the box body. The bottom of the intermediate cylinder is open, and the discharge port is located directly below the bottom opening of the intermediate cylinder. The screened sand and gravel rolls into the discharge port from the bottom opening of the intermediate cylinder and falls into the drawer of the box body. The drawer facilitates the periodic removal and cleaning of the collected sand and gravel, ensuring the continuous and effective use of the collection box. The pull-out opening on the front side of the box body makes the installation and removal of the drawer very convenient, improving the ease of operation.

[0009] Preferably, the end of the feed cylinder furthest from the intermediate cylinder is open, serving as the feed inlet for the forage. The size of this opening is designed according to actual feeding requirements to ensure that the forage can enter the feed cylinder smoothly and quickly. A guide plate can also be installed at the feed inlet, which is fixed at an angle to the edge of the feed cylinder opening. Its function is to accurately guide the forage into the feed cylinder, preventing the forage from spilling outside the device during the feeding process, thus avoiding waste of forage and clutter in the field.

[0010] Preferably, the aperture of the second filter screen is smaller than that of the first filter screen, so that when the screening assembly is flipped and inverted, larger sand and gravel on the first filter screen fall onto the second filter screen, which can prevent sand and gravel from getting stuck on the second filter screen and can be discharged along the second filter screen, ensuring the efficient and stable operation of the screening device.

[0011] Preferably, a vacuum cleaner is fixedly installed on the outside of the discharge cylinder, located above the second filter screen and connected to the discharge cylinder. The specific model of the vacuum cleaner can be a common industrial vacuum cleaner model on the market, such as the XX-1000 model. This model of vacuum cleaner has a large suction power and capacity, which can meet the adsorption needs of dust and fine impurities during the screening process of forage, ensuring a clean screening environment, reducing the impact of dust on the health of operators, and its stable performance can ensure long-term continuous operation without failure. The vacuum cleaner model can be XX-1000. The vacuum cleaner can effectively adsorb the dust generated during the screening process, preventing dust from escaping into the surrounding environment. This improves the air quality at the work site, reduces the harm to the health of operators, and avoids dust accumulation inside the device, which would affect the normal operation of the device and the screening effect.

[0012] Preferably, both ends of the intermediate cylinder are fixedly connected to a ring plate one, and the ends of the feed cylinder and discharge cylinder near the intermediate cylinder are fixedly connected to a ring plate two. The internal threads of the ring plate two and the ring plate one are fitted with fixing bolts, which tightly connect the ring plate one and the ring plate two together, thereby achieving a stable assembly of the feed cylinder, the intermediate cylinder and the discharge cylinder. This connection method is not only simple in structure and convenient to install, but also ensures the firmness and sealing of the connection between the cylinders, effectively preventing the leakage of grass and sand from the connection during the screening process, ensuring the normal operation of the screening device and the screening quality. When it is necessary to clean, repair or replace parts of the screening device, it can be easily and quickly disassembled by simply unscrewing the fixing bolts, which greatly improves maintenance efficiency and operability.

[0013] Preferably, the waste discharge port and the discharge port are symmetrically arranged on the outer wall of the discharge cylinder. When the screening component is flipped, the downward position of the waste discharge port and the discharge port can be changed to facilitate the discharge of grass or sand and gravel impurities.

[0014] This utility model provides a forage screening device for beef cattle farming, which has the following beneficial effects: This forage screening device for beef cattle breeding uses a servo motor to drive gear two to rotate, which in turn drives gear one to rotate, thereby causing the middle cylinder to rotate and the feed cylinder and discharge cylinder at both ends to flip and rotate. This makes the screening component present an inverted "V" shape. When the screening component is struck, the sand and gravel stuck in the filter screen one are shaken off and roll along the filter screen two to the left and right ends of the screening component, and are discharged out from the feed cylinder opening and the waste discharge port, respectively, which facilitates the cleaning of larger sand and gravel.

[0015] This forage screening device for beef cattle breeding allows the feed cylinder and discharge cylinder to be separated from the intermediate cylinder by removing the fixing bolts connecting the second ring plate and the first ring plate. The separation design of the screening components facilitates maintenance of the internal parts of the screening components. Attached Figure Description

[0018] This utility model provides a forage screening device for beef cattle breeding.

[0019] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5The system includes a collection box 1, a tilting assembly 2 on top of the collection box 1, and a screening assembly 3 inside the tilting assembly 2. The screening assembly 3 includes an intermediate cylinder 31 and a feed cylinder 32 and a discharge cylinder 33 located at the left and right ends of the intermediate cylinder 31. A filter screen 34 and a filter screen 35 extending into the feed cylinder 32 and discharge cylinder 33 are fixedly installed inside the intermediate cylinder 31. The filter screen 34 is located at the lower part of the intermediate cylinder 31, and the filter screen 35 is located at the upper part of the intermediate cylinder 31. The discharge cylinder 33... Waste discharge port 5 and material discharge port 4 are fixedly connected on the outer side wall away from the middle cylinder 31; the flipping assembly 2 includes a support frame 21 fixedly installed on the top of the collection box 1, the middle cylinder 31 is rotatably connected to the inside of the support frame 21, the feed cylinder 32 is fixedly installed on the outside of the middle cylinder 31, the top of the support frame 21 is fixedly installed on the horizontal plate 23, the top of the horizontal plate 23 is fixedly installed on the servo motor 24, and the output shaft of the servo motor 24 is fixedly installed on the outside of the gear 25 that meshes with the gear 1 22.

[0020] Two conveying augers 36 are rotatably installed inside the feed cylinder 32 and the discharge cylinder 33. The two conveying augers 36 are connected by a universal joint at their close ends. A drive motor 37 connected to the conveying augers 36 inside the discharge cylinder 33 is fixedly installed at the end of the discharge cylinder 33 away from the intermediate cylinder 31.

[0021] The collection box 1 includes a box body 11. A pull-out opening 12 is provided on the front side of the box body 11. A drawer 13 is movably installed inside the pull-out opening 12. A discharge port 14 is provided on the top of the box body 11. The bottom of the intermediate cylinder 31 is open. The discharge port 14 is located directly below the bottom opening of the intermediate cylinder 31.

[0022] The end of the feed cylinder 32 away from the intermediate cylinder 31 is open.

[0023] The pore size of filter screen 2 35 is smaller than that of filter screen 1 34.

[0024] Waste discharge port 5 and material discharge port 4 are symmetrically arranged on the outer wall of discharge cylinder 33.

[0025] In use, this utility model is as follows: the servo motor 24 on the horizontal plate 23 drives the gear 25 to rotate. The rotation of the gear 25 drives the gear 22 outside the intermediate cylinder 31 to rotate, thereby driving the intermediate cylinder 31 to rotate. The intermediate cylinder 31 drives the feed cylinder 32 and discharge cylinder 33 at both ends to rotate, so that the screening component 3 presents an inverted "V" shape. By knocking on the screening component 3, the sand and gravel stuck in the filter screen 34 are shaken off. With the knocking, they will roll along the filter screen 35 to the left and right ends of the screening component 3 and be discharged from the opening side of the feed cylinder 32 and the waste discharge port 5, respectively, thus facilitating the cleaning of the stuck sand and gravel.

[0026] Example 2, please refer to again Figure 1 , Figure 2 , Figure 3 and Figure 4 Both ends of the intermediate cylinder 31 are fixedly connected to ring plates 39. The feed cylinder 32 and the discharge cylinder 33 are fixedly connected to the end of the intermediate cylinder 31 with ring plates 310. The internal threads of ring plates 310 and ring plates 39 are fitted with fixing bolts 311.

[0027] A vacuum cleaner 38 is fixedly installed on the outside of the discharge cylinder 33, located above the filter screen 35 and connected to the discharge cylinder 33.

[0028] When using this utility model: by disassembling the fixing bolts 311 connecting the second ring plate 310 and the first ring plate 39, the feed cylinder 32 and the discharge cylinder 33 can be separated from the intermediate cylinder 31, and the feed cylinder 32 and the discharge cylinder 33 can be removed, so that the first filter screen 34 and the second filter screen 35 can be exposed. Through the separation design of the screening component 3, the internal parts of the screening component 3 can be further conveniently maintained.

[0029] Working principle: When in use, the feed material is added into the feed cylinder 32 through one end of the feed cylinder 32 opening. The drive motor 37 drives the conveying auger 36 connected to it to rotate. The discharge cylinder 33 and the conveying auger 36 in the feed cylinder 32 are driven by a universal joint, which in turn drives the conveying auger 36 in the feed cylinder 32 to rotate synchronously, conveying the feed material from the feed cylinder 32 to the intermediate cylinder 31 and from the intermediate cylinder 31 to the discharge cylinder 33 and discharged from the discharge port 4. During the conveying process, the sand and gravel are filtered through the filter screen 34 located below. The filtered sand and gravel pass through the filter screen 34 and flow into the screening component 3, which is set in a "V" shape, and collect into the bottom opening of the middle cylinder 31. It then falls into the discharge port 14 and finally into the drawer 13 inside the box 11 for collection. The dust passes through the filter screen 35 and is sucked away by the vacuum cleaner 38. When larger sand and gravel impurities get stuck on filter screen 34, the servo motor 24 on the horizontal plate 23 drives gear 25 to rotate. The rotation of gear 25 drives gear 22 outside the intermediate cylinder 31 to rotate, which in turn drives the intermediate cylinder 31 to rotate. The intermediate cylinder 31 drives the feed cylinder 32 and discharge cylinder 33 at both ends to rotate and flip, so that the screening component 3 is in an inverted "V" shape. By knocking on the screening component 3, the sand and gravel stuck in filter screen 34 are shaken off. Since the aperture of filter screen 34 is larger than that of filter screen 35, the sand and gravel that fall onto filter screen 35 will not get stuck. With the knocking, they will roll along filter screen 35 to the left and right ends of the screening component 3 and be discharged from the opening side of feed cylinder 32 and waste outlet 5, respectively, which facilitates the cleaning of the stuck sand and gravel. After disassembling the drive motor 37, the fixing bolts 311 connecting the second ring plate 310 and the first ring plate 39 can be removed, thereby separating the feed cylinder 32 and the discharge cylinder 33 from the intermediate cylinder 31. The feed cylinder 32 and the discharge cylinder 33 can then be removed, exposing the first filter screen 34 and the second filter screen 35, thus facilitating the overall maintenance of the screening assembly 3.
