Description

Technical Field

[0001] The invention belongs to the technical field of pesticide production, in particular to a granulating device for pesticide production and processing. Background Art

[0002] Granular pesticides are granular preparations made by combining pesticides with suitable excipients. They can generally be divided into soluble granules, suspended granules and effervescent granules. They have the advantages of simple use, small outward diffusion and long-lasting efficacy. A granulating device is required during the processing.

[0003] However, some existing granulation devices have many problems. For example, when extruding granulation through the mesh holes in the filter cylinder, air is likely to exist inside the pesticide during the granulation process. The air accompanying the cutting can easily cause particle deformity and affect the molding effect. At the same time, the particles may be damaged under the action of external forces or when they collide with each other, thereby further reducing the particle size, making it inconvenient for users to grab and use. Summary of the invention

The driving gear 61 is fixedly mounted on the output shaft 52 , and the driven gear ring 62 is fixedly mounted on the rotating drum 3 . The driving gear 61 is meshedly connected with the driven gear ring 62 .

[0032] The first transmission assembly 6 may also be driven by a belt, and the specific structure is not limited to the above solution.

[0033] The second transmission assembly 7 includes a first gear 71, a second gear 72, and a fixed tooth 73.

[0035] A material guide frame 17 is fixedly installed at one end of the lower arc plate 9, a discharge trough 110 is opened on the shell 1 at the position of the material guide frame 17, and a side baffle 21 is fixedly installed on the shell 1 at the upper edge of the rotating drum 3, and the side baffle 21 is used to block the edge of the outer arc groove 30.

[0036] A push rod is provided on a side of the pressing roller 16 away from the blade 53 , and the push rod is used to push the mixture formed by the pressing plate 19 to below the blade 53 .

[0037] When granulating, the material is placed as a whole in the feeding chamber 12, and the material is a mass mixture of pesticides, additives, adhesives, etc., and then the first telescopic member 2 is started, and the mixture is extruded by the first telescopic member 2. When the multi-stage telescopic plate 14 moves downward, under the action of the side branch plate 15, the sub-telescopic plate 141 will be retracted, so that the edge of the sub-telescopic plate 141 fits with the side branch plate 15, so that the shape of the extruded mixture can be controlled. When the mixture is squeezed out from the side branch plate 15, under the action of the pressing roller 16, the mixture is flattened. At this time, under the action of the output shaft 52 and the blade 53, the flat mixture enters under the blade 53 under the rotation guidance of the blade 53, and the blade 53 cuts the mixture while rotating, and the flat mixture is cut into strips. The mixture, the cut strip-shaped mixture will reach one end of the upper arc plate 8 as the drum 3 rotates, and then the upper arc plate 8 is driven to rotate by a plurality of sets of fixed teeth 73. After the upper arc plate 8 rotates, the fixed teeth 73 are disengaged from the second gear 72, that is, the upper arc plate 8 is disengaged from the drum 3. At this time, the strip-shaped mixture will be located between the drum 3 and the upper arc plate 8. When the second transmission assembly 7 no longer drives the upper arc plate 8 to rotate, the upper arc plate 8 returns to its original position under the action of the third spring 20, so that it can continue to fit with the drum 3. During the process of returning to its original position, the strip-shaped mixture is cut at the edge of the inner arc groove 80, so as to form a plurality of granular mixtures. Under the continuous rotation of the drum 3, the granular mixture will be shaped into a sphere, and finally discharged from the bottom end of the lower arc plate 9 to the guide frame 17.

[0038] The first transmission assembly 6 is connected to the output shaft 52, that is, the output shaft 52 continuously rotates for cutting while the drum 3 also continuously rotates. While the drum 3 rotates, it can intermittently drive the upper arc plate 8 to rotate. Under the action of the third spring 20, the upper arc plate 8 rotates alternately in forward and reverse directions.

[0039] By placing the mass mixture under the multi-stage telescopic rod, the shape is changed by the extrusion of the multi-stage telescopic rod and the rotation of the pressure roller 16, so that the residual air can be reduced by the extrusion of the pressure roller 16, and the particle mixture can be avoided from being broken and the shape can be kept intact. In addition, the particle mixture can be shaped by the cooperation of the rotating drum 3, the lower arc plate 9 and the upper arc plate 8 to form a spherical mixture. Secondly, the cut strip mixture can be squeezed into a granular mixture under the action of the upper arc plate 8. The upper arc plate 8 returns to its original position under the action of the spring, and the mixture can be further squeezed and exhausted.

[0040] See also Figure 7 , Figure 8 , Fig. 9 In one embodiment, the lower arc plate 9 is slidably installed inside the shell 1, and a through groove 91 is opened on the lower arc plate 9. A plurality of arc-shaped flexible plates 92 corresponding to the outer arc groove 30 are arranged in the through groove 91. A third telescopic member 18 is installed on the lower arc plate 9, and a pressure plate 19 is connected to the output end of the third telescopic member 18, and the shape of the pressure plate 19 corresponds to the through groove 91.

[0041] In this embodiment, an extension plate 100 is fixedly mounted on the lower arc plate 9, a third telescopic member 18 is mounted on the extension plate 100, the arc-shaped flexible plate 92 may be made of rubber, and the cross-section of the arc-shaped flexible plate 92 may be similar to a wave shape.

[0042] By setting the lower arc plate 9 and the mounting seat 10 to be slidable, when the granular mixture is between the lower arc plate 9 and the drum 3, the lower arc plate 9 and the mounting seat 10 are driven to move in one direction. At this time, the edge of the inner arc groove 80 divides the granular mixture into two. After being divided into two, the lower arc plate 9 and the mounting seat 10 move in another direction, that is, the lower arc plate 9 and the mounting seat 10 return to their original positions. At this time, the drum 3 still keeps rotating, so that the granular mixture divided into two is separated. After separation, the third telescopic member 18 is started to drive the pressing plate 19 to extrude the arc-shaped flexible plate 92. At this time, the arc-shaped flexible plate 92 is extruded from a wave shape into an arc-shaped flat plate structure. At this time, while the drum 3 continues to rotate, the mixture divided into two can be shaped to finally form a spherical granular mixture.

[0043] See also Figure 6 , Fig.10 In one embodiment, a second telescopic member 113 is fixedly mounted on the inner wall of the shell 1, an output end of the second telescopic member 113 is connected to the lower arc plate 9, and a first spring 114 is installed between the end of the lower arc plate 9 away from the second telescopic member 113 and the shell 1.

[0048] In this embodiment, the air outlet groove 90 is connected to the heating air supply pump, and the air outlet groove 90 is located at the bottom of the inner arc groove 80. By setting the air outlet groove 90 at the bottom of the lower arc plate 9, when the granular mixture falls, the airflow will directly act on the lower surface of the granular mixture, giving the granular mixture a force, causing the granular mixture to rotate, so that the surface of the granular mixture can be preliminarily dried by the heated airflow to avoid adhesion of several granular mixtures. At the same time, setting the airflow below the inner arc groove 80 can give the granular mixture a tangential force.

[0049] See also Figure 6 In one embodiment, side support plates 15 are fixedly mounted on both sides of the shell 1 , and the side support plates 15 are inclined toward the gap between the pressure rollers 16 .
