Description

Technical Field

[0001] The utility model relates to the technical field of cow dung processing, in particular to a uniform feeding device for a cow dung briquetting machine. Background Art

[0002] With the rapid development of the breeding industry, especially the lack of effective treatment methods for cow dung, a large amount of it is stockpiled, which in turn causes environmental pollution. The emergence of the briquetting machine makes it "turn waste into treasure". Cow dung is pressed into rods or blocks by the briquetting machine, which is convenient for transportation, storage and use.

[0003] After cow dung is dried and crushed, it is put into the briquetting machine through a conveying device or manually for pressing. The vibration and noise generated during the pressing process affect the stability and reliability of the briquetting machine body. The vibration and noise generated by the briquetting machine during operation come from two aspects: First, the unevenness of the raw materials when entering the briquetting machine through the feeding device causes the pressure roller to deviate from its balance center; Second, the change in the meshing force of the gears in the gearbox of the briquetting machine or the change in the friction force between the belt and the pulley. Summary of the Utility Model

[0004] The utility model provides a uniform feeding device for a cow dung briquetting machine, which solves the problems in the background art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The uniform feeding device for a cow dung briquetting machine includes a housing. An upper bearing chamber is arranged on the upper side inside the housing, and a lower bearing chamber is arranged on the lower side inside the housing. A feeding device is arranged between the upper bearing chamber and the lower bearing chamber. Bearings are arranged at the central positions on the surfaces of the upper bearing chamber and the lower bearing chamber, and a main shaft connected to the inside of the feeding device is connected to the inside of the bearings. The feeding device is welded by a cone, a spiral blade and anti-sticking points.

[0007] As a further description of the above technical scheme:

[0008] The housing is in the shape of a hollow cylinder, and four threaded holes for connecting the upper bearing chamber and the lower bearing chamber are evenly distributed at both ends of the housing.

[0009] As a further description of the above technical scheme:

[0010] Four light holes are evenly distributed on the outer circles of the upper bearing chamber and the lower bearing chamber.

[0011] In summary, due to the adoption of the above technical scheme, the beneficial effects of the utility model are:

[0012] In the present utility model, a motor provides power to the material feeding device to make it operate at a uniform speed. When the raw materials enter the material feeding device through the feeding device, the material feeding device evenly disperses them between the spiral blades, enabling the raw materials to enter the pressing area of the briquetting machine along the spiral blades, thereby reducing the vibration and noise of the briquetting machine caused by the unevenness of the raw materials.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Referring to Figures 1 - 11 , the uniform feeding device of the cow dung briquetting machine includes a housing 6. An upper bearing chamber 11 is provided on the upper side inside the housing 6, and a lower bearing chamber 4 is provided on the lower side inside the housing 6. A feeding device 8 is arranged between the upper bearing chamber 11 and the lower bearing chamber 4. During use, the motor drives the main shaft 7, thereby driving the feeding device 8. Bearings 5 are provided at the central positions on the surfaces of the upper bearing chamber 11 and the lower bearing chamber 4, and a main shaft 7 connected to the inside of the feeding device 8 is connected inside the bearings 5. The feeding device 8 is welded by a cone, a spiral blade, and anti-sticking points. When the raw materials enter the feeding device through the feeding device or manually, the uniformly rotating spiral blade evenly disperses the raw materials between every two blades. When the raw materials fall from top to bottom along the spiral blade, the anti-sticking points distributed between the spiral blades gradually disperse them, preventing the raw materials from blocking the device, and then ensuring that the raw materials evenly enter the pressing area of the briquetting machine, thereby reducing the vibration and noise during the pressing process of the briquetting machine. As Figure 2 , Figures 7 - 9 shown, the feeding device 8 is connected to the main shaft 7 through a round key 10. The upper bearing chamber 11 and the lower bearing chamber 4 constrain the main shaft 7 through cylindrical roller bearings 5. In the upper bearing chamber 11, the bearing 5 is axially constrained by a sleeve 9 and a bearing end cover 2. The sleeve 9 and the shaft shoulder constrain the displacement of the feeding device 8 along the axis direction. The end cover 2 is connected to the upper bearing chamber 11 and the lower bearing chamber 4 through second bolts 3. As Figures 3 - 6 shown, the purpose of selecting a cone in the feeding device 8 is to convey the raw materials to the extrusion area between the pressure roller and the ring die, avoiding "secondary processing" of the raw materials and improving the working efficiency of the briquetting machine. The purpose of selecting a spiral blade in the feeding device 8 is to ensure uniformity when the raw materials enter the briquetting machine from the feeding device through the feeding device 8, so as to reduce the vibration and noise caused by uneven feeding. The width of the spiral blade in the feeding device 8 is uniform, but the height is not uniform and decreases as the diameter of the cone gradually increases. The distance between the spiral blades welded on the cone is also not uniform. The distance between the spiral blades welded at the upper end of the cone is smaller than the distance between the spiral blades welded at the lower end. The anti-sticking points on the cone are distributed between the spiral blades. The distribution characteristics of the anti-sticking points change from sparse to dense from the upper end to the lower end of the cone. The purpose is to disperse the raw materials entering the feeding device 8 through the feeding device, prevent adhesion in the feeding device 8 and cause blockage, and thus affect the production efficiency of the briquetting machine.

[0028] Furthermore, the housing 6 is in the shape of a hollow cylinder, and four threaded holes for connecting the upper bearing chamber 11 and the lower bearing chamber 4 are evenly distributed at both ends of the housing 6. The lower bearing chamber 4 of the charging device and the briquetting machine are connected together by bolts, which is convenient for installation and maintenance.

[0029] Furthermore, four light holes are evenly distributed on the outer rings of the upper bearing chamber 11 and the lower bearing chamber 4. As Figure 2 shown, the housing 6 is connected to the upper bearing chamber 11 and the lower bearing chamber 4 by the first bolts 1.

[0030] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
