Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production and preparation, in particular to an organic fertilizer extrusion granulation device. Background Art

[0002] Organic fertilizer is a kind of organic fertilizer made from the residues of animals, plants and microorganisms through composting and fermentation. Organic fertilizer is rich in organic matter (compounds containing carbon elements). The application of organic fertilizer can reduce the use of chemical fertilizers, improve soil quality, increase soil water and fertilizer retention capacity, improve soil structure, increase soil aeration and retention, and is beneficial to root growth and plant cultivation.

[0003] There is an existing double-roller extrusion granulator, which feeds organic fertilizer between a pair of relatively rotating rollers, and the outer wall of the rollers has a plurality of hemispherical grooves. As the two rollers rotate synchronously and oppositely, the organic fertilizer between the two rollers is squeezed, and the organic fertilizer raw material is squeezed into spherical particles. The particles are separated from the hemispherical grooves under the action of centrifugal force and gravity during the rotation process, thereby realizing the granulation of the material. However, the organic fertilizer raw material contains moisture and is sticky. When being squeezed, it is also easy to adhere to the hemispherical grooves, and a small amount of organic fertilizer raw material will remain in some hemispherical grooves and cannot be separated.

[0052] A hemispherical groove 2 is provided on the outer wall of the roller body 1;

[0053] A push plate 3 is arranged inside the hemispherical groove 2;

[0054] A connecting rod 4 is slidably connected to the roller body 1, and one end of the connecting rod 4 is fixedly connected to the push plate 3;

[0055] When the roller body 1 rotates, the push plate 3 located at the lower half of the roller body 1 moves out of the hemispherical groove 2 under the action of gravity and centrifugal force, exerting a thrust on the organic fertilizer raw materials remaining in the hemispherical groove 2, so as to cause the organic fertilizer raw materials to leave the hemispherical groove 2;

[0056] The rollers also include:

[0057] A circular groove 5 is provided inside the roller body 1;

[0058] The convex block 6 is fixedly arranged inside the circular groove 5, and its protruding portion 7 is always arranged downward;

[0059] The connecting rod 4 is elastically connected to the roller body 1, and the other end thereof is fixedly connected to an arc block 8. When the arc block 8 touches the protruding portion 7 of the protrusion 6, the connecting rod 4 can overcome the elasticity and drive the push plate 3 to move out of the hemispherical groove 2.

[0060] The bump 6 comprises:

[0061] The cylinder 9 is located inside the circular groove 5;

[0062] The protruding portion 7 is integrally formed with the cylindrical body 9 and has a curved surface and a straight surface;

[0063] Between the connecting rod 4 and the roller body 1 there are:

[0064] The through slot 10 is adapted to the connecting rod 4 and is slidably connected to the connecting rod 4;

[0065] The elastic groove 11 is connected with the through groove 10;

[0066] A fixing ring 12 is fixedly sleeved on the outer wall of the connecting rod 4 and is slidably connected to the elastic groove 11;

[0067] A compression spring 13 is sleeved on the outer wall of the connecting rod 4, one end of which is connected to the fixing ring 12, and the other end is connected to the elastic groove 11;

[0068] Wherein, under the elastic action of the compression spring 13, the fixing ring 12 is located at the highest point of the elastic groove 11;

[0069] Push plate 3 has:

[0070] A vibration groove 14 is provided inside the push plate 3;

[0071] A metal ball 15 is arranged inside the vibration groove 14;

[0072] When the push plate 3 moves, the metal ball 15 swings freely in the vibration groove 14 and hits the push plate 3, so that the push plate 3, the connecting rod 4 and the roller body 1 all vibrate, which helps to shake off the organic fertilizer raw materials remaining in the hemispherical groove 2;

[0073] The extrusion granulation device also includes:

[0074] Housing 16;

[0075] Two rollers are symmetrically arranged inside the housing 16;

[0076] Two fixed shafts 17, fixedly connected to the inside of the housing 16 and passing through the rollers, and fixedly connected to the protrusions 6;

[0077] A support block 21 is located below the housing 16 and is fixedly connected to the housing 16, and is used to support the housing 16 and the structure on the housing 16;

[0078] A guide plate 22 is located below the housing 16 and is fixedly connected to the housing 16, and is used to guide the organic fertilizer extruded into particles to slide and roll out;

[0079] The granulation device also includes:

[0080] The sleeve 18 is a hollow structure, which is slidably sleeved on the outer wall of the fixed shaft 17, and one end of which is coaxially fixedly connected to the roller body 1;

[0081] The gear 19 is fixedly sleeved on the outer wall of the sleeve 18, and the two gears 19 are meshed and connected;

[0082] The rotating motor 20 is installed outside the housing 16 , and its output end is fixedly connected to one of the sleeves 18 .

[0083] Working principle:

[0084] Start the rotary motor 20 to drive the two sleeves 18 to rotate in opposite directions, thereby driving the two rollers to rotate in opposite directions;

[0085] The organic fertilizer raw material is put into the position between the two rollers, and the rollers rotating synchronously in opposite directions squeeze the organic fertilizer raw material and squeeze it into spherical particles;

[0086] The rotation of the roller body 1 drives each push plate 3 to rotate accordingly, and the arc block 8 inside the circular groove 5 also rotates accordingly. When approaching the convex block 6, the arc surface of the arc block 8 touches the arc surface of the convex part 7 of the convex block 6, overcoming the elastic force of the compression spring 13 and driving the push plate 3 to move away from the circular groove 5;

[0087] The push plate 3 moving away from the circular groove 5 pushes out the organic fertilizer raw material in the hemispherical groove 2. When the arc surface of the arc block 8 is no longer in contact with the arc surface of the protruding portion 7 of the convex block 6, it rebounds rapidly under the elastic force of the compression spring 13, and the metal ball 15 swings freely in the vibration groove 14 and hits the push plate 3, causing the push plate 3, the connecting rod 4 and the roller body 1 to vibrate.

[0088] It should be noted that:

[0089] Reference Figure 4 , where the directions of the two arrows represent the directions in which the two rollers rotate synchronously and oppositely;

[0090] The arc block 8 also has an arc surface and a straight surface. When the arc surface of the arc block 8 separates from the arc surface of the protruding portion 7 of the convex block 6, the elastic force of the compression spring 13 causes the arc block 8 to rebound quickly, and the straight surface of the arc block 8 quickly slides into contact with the straight surface of the protruding portion 7 of the convex block 6, and the connecting rod 4 quickly collides with the protruding portion 7 of the convex block 6 to also generate vibration.
