Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production, in particular to an organic fertilizer screening machine. Background Art

[0002] Organic fertilizer screening machines can remove large impurities from organic fertilizer, making the particles more uniform and improving its purity and quality. This is crucial for improving crop absorption efficiency and soil improvement. For example, in flower cultivation, using high-quality, screened organic fertilizer can help flowers grow stronger and produce more vibrant blooms.

[0003] It generally consists of a feeder, screening device, screen (drum), vibrating mechanism, transmission, discharge device, and support frame. The entire screening machine is supported by the support frame, which is generally made of steel and connected by welding or bolts. The frame must be strong and stable enough to withstand the vibration of the screening machine during operation and the weight of the material.

[0004] The screens currently used are generally cylindrical, and the supporting frame is tilted as a whole, so that the screen cylinder is tilted at a certain angle, allowing the material to enter from the upper inlet, be screened, and then discharged through the bottom outlet to complete the screening.

[0005] However, in the actual production process, due to the fixed support angle of the support frame, the material forward speed is constant and difficult to adjust, which cannot meet the needs of efficient production. At the same time, when the cylindrical screen continues to work, it is prone to blockage, affecting the screening effect and is difficult to clean. Summary of the Invention

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-4 A fertilizer screening machine includes a frame 1, an empty slot 2 is opened inside the frame 1, and discharge slots 3 arranged at equal distances are provided at the bottom of the empty slot 2. Both ends of the frame 1 are fixedly connected with mounting frames 4, and the two mounting frames 4 are equipped with screening mechanisms 5. An adjusting mechanism 6 is installed on the right side of the bottom of the frame 1, and two elastic support members 7 are installed on the right side of the frame 1.

[0024] In the present invention, the frame 1 is used as the supporting frame of the device. When in use, the screening mechanism 5 is operated first, and then the inside of the screening mechanism 5 is added from the high position on the left. As the screening mechanism 5 operates, the organic fertilizer gradually runs to the low position along the inside of the screening mechanism 5, and unqualified particles are screened out. When it is necessary to adjust the inclination angle of the screening mechanism 5 to increase the screening efficiency, the adjusting mechanism 6 is driven to move to the left along the bottom of the frame 1 to lower its left end, and the elastic support member 7 always supports the left end during the adjustment process, so that the frame 1 is more stable when adjusted, thereby achieving the advantage of the device having the ability to flexibly adjust the screening inclination angle and to clean the screening cylinder in real time to avoid clogging. This solves the problem in the prior art that the support angle of the support frame is fixed, resulting in a constant material forward speed, which is difficult to adjust and cannot meet the needs of efficient production. At the same time, when the cylindrical screen continues to work, it is prone to clogging, affecting the screening effect and being difficult to clean.

[0025] See also Figure 1 and Figure 3, wherein: the screening mechanism 5 includes a driving motor 51, a transmission shaft 52, a screening drum 53 and an anti-blocking mechanism 54. The driving motor 51 is fixedly mounted on the right mounting frame 4. The output end of the driving motor 51 is fixedly connected to the transmission shaft 52 through a coupling. The other end of the transmission shaft 52 is rotatably connected to the left mounting frame 4. The inner side of the screening drum 53 is fixedly mounted to the outer side of the transmission shaft 52. The anti-blocking mechanism 54 is installed between the transmission shaft 52 and the two mounting frames 4.

[0026] In the present invention, the driving motor 51 is started to drive the transmission shaft 52 to rotate and drive the screening drum 53 to rotate, thereby realizing the transportation and screening of organic fertilizer, and driving the anti-blocking mechanism 54 to run synchronously, and performing real-time synchronous cleaning on the screening drum 53 to avoid blockage.

[0027] See also Figure 1 and Figure 2 , wherein: the anti-blocking mechanism 54 includes two belt pulleys 541, a transmission belt 542, a rotating rod 543 and elastic rubber strips 544 arranged at equal distances. The two ends of the rotating rod 543 are respectively rotatably connected to the two mounting frames 4. The two belt pulleys 541 are respectively fixedly connected to the rotating rod 543 and the transmission shaft 52. The outer sides of the two belt pulleys 541 are both transmission-connected to the transmission belt 542. The elastic rubber strips 544 are equidistantly arranged on the outer side of the rotating rod 543. The elastic rubber strips 544 are in contact with the outer side of the screening drum 53.

[0028] In the present invention, the transmission shaft 52 and the rotating rod 543 are linked by two belt pulleys 541 and a transmission belt 542. As the rotating rod 543 rotates, the elastic rubber strip 544 is driven to continuously whip the outer surface of the screening drum 53, causing it to vibrate, continuously cleaning the adhered materials and avoiding blockage.

[0029] See also Figure 1 and Figure 4 , wherein: the adjustment mechanism 6 includes a sliding block 61, a roller 62 and a linear drive rail 63, the linear drive rail 63 is fixedly installed in contact with the bottom of the frame 1, the top of the sliding block 61 is movably installed to the bottom of the linear drive rail 63, and the roller 62 is installed to the bottom horizontal surface of the sliding block 61.

[0030] In the present invention, the linear drive rail 63 is activated to drive the sliding block 61 to move along the bottom of the frame 1, thereby changing the support point position to adjust the tilt angle. At the same time, the roller 62 at the bottom is used to make the sliding block 61 more flexible in movement.

[0031] See also Figure 1 and Figure 4, wherein: the elastic support member 7 includes a fixed block 71, a vertical rod 72 and a spring 73, one side of the fixed block 71 is hinged to the bottom of the right end of the frame 1, the top of the vertical rod 72 passes through the top of the fixed block 71 and is slidably connected to it, the spring 73 is sleeved on the outside of the vertical rod 72, the top of the spring 73 is fixedly connected to the fixed block 71, and the bottom end of the spring 73 is fixedly connected to the outside of the vertical rod 72.

[0032] In the present invention, the bottom end of the vertical rod 72 contacts the ground. As the height of the right end of the rack 1 is adjusted, the height of the fixed block 71 changes accordingly. It slides along the vertical rod 72 and uses the spring 73 to provide auxiliary support for the fixed block 71, making it more stable during adjustment.

[0033] See also Figure 1 , wherein: a guide plate 8 is fixedly connected to the bottom of the right end of the frame 1.

[0034] In the present invention, the material discharging at the lower right end of the screening drum 53 is guided by the material guide plate 8, so that the material discharging is more concentrated and smooth.

[0035] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
