Description

Technical Field

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

[0002] Organic fertilizer is also called "farmyard manure"; all organic matter used as fertilizer is called organic fertilizer; including human feces, manure, compost, green manure, cake fertilizer, biogas fertilizer, etc.; it has the characteristics of many types, wide sources, and long fertilizer effect. Since the particles of organic fertilizer are of different sizes after production, it is necessary to perform multi-stage screening of the organic particles to ensure the overall quality of the organic fertilizer particles.

[0003] In the existing technology, organic fertilizers are generally screened using a drum screening machine. However, during the screening process, if the fertilizer contains a large amount of fertilizer close to the size of the sieve holes, these fertilizers are very likely to clog the sieve holes, making it impossible for some small fertilizer particles to pass through the sieve holes and be completely screened out during subsequent screening, thus affecting the subsequent screening effect. How to invent an organic fertilizer screening machine to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides an organic fertilizer screening machine, which aims to improve the problem that the screening effect is affected by the clogging of the sieve holes of the screening machine.

[0005] The utility model is achieved in this way:

[0008] Preferably, the outer wall of the connecting frame is fixedly connected to a limiting ring, the outer wall of the limiting ring is rotatably connected to the inner wall of the adjusting frame, the screen is made of elastic material, the inner wall of one of the sliders is slidably connected to the outer wall of the guide rod, one end of the loading bin extends into the fixed frame, and the cross bar inside the fixed frame does not contact the loading bin when rotating.

[0009] Preferably, both ends of the adjusting rod are rotatably connected to the inner wall of the body, a plurality of reciprocating thread grooves are provided on the outer wall of the adjusting rod, and the inner wall of the other slider is threadedly connected to the outer wall of the adjusting rod near the reciprocating thread grooves.

[0010] Preferably, the output end of the motor is fixedly connected to one end of the main shaft, one end of the main shaft is fixedly connected to a first pulley, one end of the adjusting rod is fixedly connected to a second pulley, and a first belt is connected for transmission between the first pulley and the second pulley.

[0011] By adopting the above technical solution, during the process of screening organic fertilizers, the main shaft drives the entire screening assembly to rotate, and at the same time the adjusting rod on one side rotates, and the reciprocating thread groove opened on the outer wall causes the adjusting frame to drive the connecting frame to move back and forth during the rotation, so that the tension of the screen between the frames is repeatedly adjusted to cause the screen to vibrate, thereby clearing the fertilizer in the screen hole and avoiding blockage of the screen.

[0012] Preferably, both ends of the body are fixedly connected with ear plates, the inner wall of the ear plate is rotatably connected with a rotating shaft, and the outer wall of the rotating shaft close to the screen is fixedly connected with a plurality of flapping leaves.

[0014] Preferably, a second belt is connected between the third pulley and the fourth pulley, and the beating leaves are in contact with the screen during rotation.

[0015] By adopting the above technical solution, the adjusting rod drives the adjusting frame to move back and forth while the rotating shaft at one end rotates at the same time, so that the outer flapping leaves slide and squeeze against the screen during the rotation process, which is beneficial to vibrate and clear the fertilizer in the screen holes and reduce the possibility of screen blockage.

[0016] The beneficial effects of the utility model are:

[0017] During the operation of the screening assembly, the adjacent adjustment frames are set to move in opposite directions, so that the screen tension accuracy between the adjustment frames can be repeatedly adjusted. The screen is constantly stretched and rebounded to generate slight vibrations, which helps to reduce the accumulation of materials on the screen, thereby reducing the blockage of the screen holes. At the same time, the rotating shaft drives the outer flapping leaves to rotate when the screening assembly is working, so that the flapping leaves slide and squeeze against the outer wall of the screen, causing the screen to sag inward. At the same time, after the flapping leaves are out of contact, the screen rebounds and generates vibrations in the process, which vibrates and clears the fertilizer blocked in the screen holes, reduces the blockage of the screen, and keeps the screen holes unobstructed to ensure the screening effect.

[0028] Example, refer to Figure 1-Figure 7 , an organic fertilizer screening machine includes a body 1 and a fixed frame 10 arranged on the body 1, a mounting frame 2 is fixedly connected to the outer wall of one side of the body 1, a motor 3 is installed on the mounting frame 2, an end of the body 1 away from the motor 3 is fixedly connected to a support rod 4, the upper end of the support rod 4 is fixedly connected to a loading bin 5, chutes 6 are opened on the inner walls of both sides of the body 1, the inner wall of one chute 6 is fixedly connected to a guide rod 18, and an adjusting rod 19 is installed on the inner wall of the other chute 6, a first discharge chute 8 is opened at one end of the body 1, and a second discharge chute 9 is opened at the bottom of one side of the body 1;

[0029] A fixing rod 12 is fixedly connected between the two fixing frames 10, a main shaft 11 that is rotatably connected to the inner wall of the body 1 is fixedly connected to one side of the fixing frame 10, a plurality of connecting frames 14 are slidably connected to the outer wall of the fixing rod 12, a screen 13 is fixedly connected between the connecting frames 14 and between the connecting frames 14 and the fixing frames 10, an adjusting frame 16 is installed on the outer wall of the connecting frame 14, and sliders 17 that are slidably connected to the inner wall of the slide groove 6 are fixedly connected on both sides of the adjusting frame 16.

[0030] Furthermore; the outer wall of the connecting frame 14 is fixedly connected to the limit ring 15, the outer wall of the limit ring 15 is rotatably connected to the inner wall of the adjusting frame 16, the screen 13 is made of elastic material, the inner wall of one slider 17 is slidably connected to the outer wall of the guide rod 18, one end of the loading bin 5 extends into the fixed frame 10, and the cross bar inside the fixed frame 10 does not contact the loading bin 5 when rotating, the two ends of the adjusting rod 19 are rotatably connected to the inner wall of the body 1, the outer wall of the adjusting rod 19 is provided with a plurality of reciprocating thread grooves 20, the inner wall of another slider 17 is threadedly connected to the outer wall of the adjusting rod 19 near the reciprocating thread groove 20, the output end of the motor 3 is fixedly connected to one end of the main shaft 11, one end of the main shaft 11 is fixedly connected to a first pulley 21, one end of the adjusting rod 19 is fixedly connected to a second pulley 22, and a first belt 23 is transmission-connected between the first pulley 21 and the second pulley 22.

[0031] It should be noted that: in the process of screening organic fertilizers, the main shaft 11 drives the entire screening assembly to rotate, and at the same time, the adjusting rod 19 on one side rotates synchronously with the belt and the main shaft 11 through the pulley. The reciprocating thread groove 20 on the outer wall of the adjusting rod 19 cooperates with the slider 17 during the rotation process to make the adjusting frame 16 drive the connecting frame 14 to move back and forth on the slide 6. The multiple connecting frames 14 move in opposite directions between adjacent pairs, so that the tension of the screen 13 between the frames is repeatedly adjusted. During the adjustment process, the screen 13 is continuously stretched and rebounded to generate slight vibration, which helps to reduce the accumulation of material on the screen 13, thereby reducing the blockage of the screen holes.

[0032] Furthermore, ear plates 7 are fixedly connected to both ends of the body 1, and the inner wall of the ear plate 7 is rotatably connected to a rotating shaft 25.

[0033] It should be noted that: while the adjusting rod 19 drives the adjusting frame 16 to move back and forth, the rotating shaft 25 at one end rotates in conjunction with the second belt 28 through the third pulley 24 and the fourth pulley 27, so that the outer flapping leaves 26 slide and squeeze against the outer wall of the screen 13 during the rotation process, causing it to be concave inward. At the same time, after the flapping leaves 26 are out of contact, the screen 13 rebounds, thereby generating vibration in the process, vibrating and clearing the fertilizer blocked in the screen hole, and reducing the blockage of the screen 13.

[0034] The working principle of this organic fertilizer screening machine:

[0035] The organic fertilizer is put into the screening assembly through the feeding bin 5, and the motor 3 is started to control the main shaft 11 to drive the screening assembly to rotate and screen the organic fertilizer. At the same time, the adjusting rod 19 on one side is synchronously rotated by the first pulley 21 and the second pulley 22 in conjunction with the first belt 23. The reciprocating thread groove 20 on the outer wall of the adjusting rod 19 cooperates with the slider 17 during the rotation process to make the adjusting frame 16 drive the connecting frame 14 to reciprocate on the slide 6. The multiple connecting frames 14 move in opposite directions between each other, so that the tension of the screen 13 between the frames is repeatedly adjusted. During the adjustment process, the screen 13 is continuously stretched and rebounded to generate slight vibration, which helps to reduce the accumulation of materials on the screen 13. Thereby reducing the blockage of the sieve holes, at the same time, the rotating shaft 25 at one end is rotated by the third pulley 24 and the fourth pulley 27 in cooperation with the second belt 28, so that the outer flapping leaves 26 slide and squeeze against the outer wall of the screen 13 during the rotation, causing it to be concave inward, and at the same time, after the flapping leaves 26 are disengaged, the screen 13 rebounds, thereby generating vibration in the process, vibrating and clearing the fertilizer blocked in the sieve holes, reducing the blockage of the screen 13, and then the large-particle organic fertilizer is discharged and collected through the first discharge chute 8 under the action of gravity, and the small-particle organic fertilizer is discharged and collected through the second discharge chute 9, avoiding the blockage of the screen 13 during the screening process, thereby ensuring the screening effect.

[0036] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
