Description

Technical Field

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

[0002] The choice of forage is crucial for the growth and development of beef cattle. Dry rice straw and dry wheat straw are common sources of roughage for beef cattle, rich in crude fiber, which helps with digestion. Corn stalks and sorghum stalks are also important roughage for beef cattle. With proper processing, palatability and digestibility can be improved. Therefore, forage is the main feed for beef cattle. When processing forage, it is necessary to screen it to remove dust, stones, impurities, and large particles to avoid adverse effects on the digestive system of beef cattle.

[0003] Currently, patent CN218079009U discloses a dust screening device for beef cattle feed, including a base plate. The device is characterized by: the lower ends of the vertical plates of symmetrical L-shaped plates fixedly connected to the upper side of the base plate; one end of each horizontal plate of the two L-shaped plates having a corresponding circular hole; corresponding circular shafts movably connected within each of the two circular holes; one end of each of the two circular shafts fixedly connected to both sides of a working barrel; a motor fixedly connected to the upper center of the working barrel; the output shaft of the motor passing through the upper center of the working barrel; and the end of the motor's output shaft being fixedly... A fixed connection is made to the upper end of a round rod, which is set inside the working barrel. A set of evenly arranged stirring rods are fixedly connected to the lower end of the round rod. A filter plate is provided inside the working barrel, and the outer side of the filter plate is fixedly connected to the lower part of the inner wall of the working barrel. The motor drives the round rod to rotate, and the round rod drives the set of stirring rods to rotate, so that the set of stirring rods stirs the hay in the working barrel, causing the dust in the hay to rise and be extracted by the vacuum cleaner more quickly. At the same time, the fine sand and gravel particles in the hay fall to the bottom of the working barrel through the round holes provided on the filter plate, thus completing the dust screening of the hay.

[0004] However, the above-mentioned hay dust screening device still has the following problems during use: during the screening of hay, only one set of stirring structure is set, so it is difficult to guarantee the screening effect of hay during use. In addition, during the screening process, some small stones block the screening holes due to their position, thus affecting the screening effect of dust in hay. Furthermore, during the removal of hay, the stones at the bottom will be mixed into the hay. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust screening device for beef cattle feed. Through multiple sets of stirring structures, the feed can be mixed, and the feed can be dispersed and dried by blowing air, which facilitates the thorough screening of dust in the feed.

[0006] This utility model provides the following technical solution: a dust screening device for beef cattle feed, comprising a screening box, a heating box fixedly installed at its upper end, and the heating box being connected to an external blower; a motor fixedly installed at the upper end of the screening box, and the output end of the motor being connected to a stirring shaft; a stirring rod fixedly installed at the upper end of the outer surface of the stirring shaft, and a stirring rod fixedly installed at the lower end of the outer surface of the stirring shaft; a filter plate fixedly installed on the inner surface of the screening box; a heating wire fixedly installed inside the heating box; a sealing plate fitted to the upper end of the screening box, and a movable plate fixedly installed on the sealing plate; an mounting plate fixedly installed on the screening box, and a guide rod fixedly installed on the mounting plate; a push spring fixedly installed on the mounting plate, and the push spring being connected to the movable plate.

[0007] Furthermore, bearings are fixedly installed on both the screening box and the filter plate, and the stirring shaft forms a rotating mechanism with the screening box and the filter plate through the bearings installed on the screening box and the filter plate. The filter plate has through screening holes. Through the above structure, dust can be screened through the filter plate.

[0008] Furthermore, a through square groove is provided in the middle of the movable plate, and the movable plate is slidably connected to the guide rod through the square groove. A positioning hole is provided on the side of the movable plate. With the above structure, the movable plate can be guided and limited by the guide rod, thereby preventing the movable plate from rotating.

[0009] Furthermore, a fixed plate is fixedly installed on the screening box, and a positioning rod is provided through the fixed plate. A positioning spring is fixedly installed on the positioning rod, and the positioning spring is fixedly installed on the fixed plate. Through the above structure, the positioning rod can easily position the moving plate after it has been moved.

[0010] Furthermore, the screening box is symmetrically equipped with support shafts on the left and right sides, and the support shafts are rotatably mounted on the support plate. The support plate is provided with screw mounting holes. Through the above structure, it is easy to support the screening box without affecting the rotation of the screening box.

[0011] Furthermore, an electric telescopic rod is fixedly installed on the support plate, and a movable rack is fixedly installed on the electric telescopic rod. A rotating gear is fixedly installed on the support shaft, and the rotating gear meshes with the movable rack. Through the above structure, the rotating gear can be driven to rotate by the movement of the movable rack, thereby causing the screening box to start rotating.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This forage dust screening device for beef cattle uses a rotating stirring rod to break up the forage, followed by a cleaning plate that brushes the filter plate to prevent dust and small stones from clogging the screening holes and affecting the screening effect. A heating wire heats the incoming air to dry the forage, preventing it from clumping and improving screening efficiency. The moving rack drives the rotating gears and screening box to automatically unload the screened forage. A sealing plate ensures a relatively sealed environment within the screening box during drying and screening processes. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-5This utility model provides a technical solution: a dust screening device for beef cattle feed, including a screening box 1, a heating box 7 fixedly installed at its upper end, and the heating box 7 being connected to an external blower; a motor 2 fixedly installed at the upper end of the screening box 1, and the output end of the motor 2 being connected to a stirring shaft 3; a stirring rod 4 fixedly installed at the upper end of the outer surface of the stirring shaft 3, and a stirring rod 4 fixedly installed at the lower end of the outer surface of the stirring shaft 3; a filter plate 6 fixedly installed on the inner surface of the screening box 1; a heating wire 8 fixedly installed inside the heating box 7; a sealing plate 9 fitted to the upper end of the screening box 1, and a movable plate 10 fixedly installed on the sealing plate 9; an auxiliary plate 12 fixedly installed on the screening box 1, and a guide rod 11 fixedly installed on the auxiliary plate 12. A push spring 13 is fixedly installed on the mounting plate 12, and the push spring 13 is connected to the moving plate 10. Bearings are fixedly installed on both the screening box 1 and the filter plate 6. The stirring shaft 3 forms a rotating mechanism with the screening box 1 and the filter plate 6 through the bearings installed on the screening box 1 and the filter plate 6. The filter plate 6 has a through screening hole. A through square groove is opened in the middle of the moving plate 10, and the moving plate 10 is slidably connected to the guide rod 11 through the square groove. A positioning hole is opened on the side of the moving plate 10. A fixing plate 14 is fixedly installed on the screening box 1, and a positioning rod 15 is provided through the fixing plate 14. A positioning spring 16 is fixedly installed on the positioning rod 15, and the positioning spring 16 is fixedly installed on the fixing plate 14.

[0022] When screening of the forage is required, pull the positioning rod 15 to move it away from the fixed plate 14. Since a positioning spring 16 is fixedly installed on the positioning rod 15, it begins to stretch and deform. Then, pull the moving plate 10. Because the moving plate 10 is connected to the sealing plate 9, the sealing plate 9 begins to slide. Since a push spring 13 is fixedly installed on the moving plate 10, it begins to compress and deform. Then, release the positioning rod 15. Under the action of the restoring deformation of the positioning spring 16, the positioning spring 16 begins to drive the positioning rod 15 to move, thus engaging and fixing the moving plate 10, thereby engaging and fixing the opened sealing plate 9. Afterward, the forage can be added into the screening box 1. Once the forage is added, pull the positioning rod 15 so that it is no longer in contact with the moving plate 10. Then, the push spring 13... The moving spring 13 then begins to recover its deformation, pushing the moving plate 10 and the sealing plate 9. At this time, the two sealing plates 9 begin to fit tightly together, ensuring that the airflow does not leak excessively from the screening box 1. Then, the motor 2 starts to work. Since the output end of the motor 2 is connected to the stirring shaft 3, the stirring shaft 3 begins to rotate, thereby driving the stirring rod 4 and the cleaning plate 5 to rotate. At the same time, the heating box 7 is connected to the blower, and the blower starts to work, thus sending air into the screening box 1. The heating wire 8 starts to work, and the heating wire 8 begins to heat the incoming air, thereby drying the forage. During the drying process, the forage is stirred, thus achieving thorough drying and stirring of the forage. At this time, the dust in the forage is screened out through the filter plate 6, thereby removing the dust from the forage.

[0023] The screening box 1 is symmetrically equipped with support shafts 17 on the left and right sides, and the support shafts 17 are rotatably mounted on the support plate 19. The support plate 19 is provided with screw mounting holes. An electric telescopic rod 20 is fixedly installed on the support plate 19, and a movable rack 21 is fixedly installed on the electric telescopic rod 20. A rotating gear 18 is fixedly installed on the support shafts 17, and the rotating gear 18 and the movable rack 21 mesh with each other.

[0024] After removing the dust from the forage, pull the sealing plate 9 to open it. The positioning rod 15 can then lock and fix the moving plate 10. After that, the electric telescopic rod 20 starts to work. Since the upper end of the electric telescopic rod 20 is fixedly installed with a moving rack 21, and the moving rack 21 meshes with the rotating gear 18, the rotating gear 18 starts to rotate. Since the rotating gear 18 is fixedly installed on the support shaft 17, the support shaft 17 starts to rotate. As the support shaft 17 rotates, it drives the screening box 1 to rotate, that is, the screening box 1 begins to tilt, so that the forage inside the screening box 1 can be taken out.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
