Description

Technical Field

[0001] The utility model relates to the field of fertilizer granulation, in particular to a granulator capable of adjusting particle size. Background Art

[0002] Fertilizer granulation is to mix the raw materials required for fertilizer manufacturing in a certain proportion, and then use the mixed and stirred raw materials to granulate them using a fertilizer granulator. The current fertilizer granulators can be divided into several types according to their working principles, such as extrusion granulators, disc granulators and spray granulators.

[0003] The extrusion fertilizer granulator currently on the market mainly includes components such as feeding assembly, extrusion assembly, power assembly and cutting assembly. When in use, the mixed raw materials are placed into the machine chamber through the feeding assembly, and then the extrusion assembly is started. Most of the current extrusion assemblies include a pressing cylinder, a pressing plate and a template. At the same time, a die hole is set on the template. When the extrusion assembly is started, the pressing plate will extrude the raw materials so that the raw materials pass through the die hole. At the same time, the cutting assembly will cut the raw materials passing through the die hole under the drive of the driving assembly. The driving mechanism will control the movement frequency and speed of the cutting knife so that it can match the extrusion speed of the material, thereby obtaining uniform fertilizer particles.

[0004] However, in actual use, due to different needs, customers may need different fertilizer granules, so different templates are needed. Since the template of the above-mentioned extrusion fertilizer granulator is installed inside the machine room by bolts, when replacing the template, the machine room needs to be opened and then the template is replaced. This will undoubtedly make the replacement of the template very inconvenient. In order to improve the use efficiency, a granulator with adjustable particle size is proposed, which makes it easy to replace the template to adapt to the granulation of fertilizers of different particle sizes. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a granulator with adjustable particle size to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a granulator with adjustable particle size, comprising a body, a template slidably mounted in the body, a mounting track corresponding to the template provided on the body, and a handle located on the outside of the body mounted at the end of the template;

[0007] The body is equipped with multiple groups of extrusion cylinders corresponding to the templates, and the tops of the extrusion cylinders are in contact with the outer wall of the template. The body is equipped with springs connected to the extrusion cylinders. A positioning cylinder is installed on the top of one group of the extrusion cylinders. The template is provided with positioning holes corresponding to the positioning cylinders, and the positioning cylinders are located in the positioning holes.

[0008] A connecting frame connected to the extrusion cylinder is slidably installed inside the machine body, and the machine body is further provided with a driver for driving the connecting frame.

[0009] By adopting the above technical solution, the handle can be pulled from the outside of the machine body for replacement without opening the machine chamber, reducing the difficulty of template replacement, improving the use efficiency, and enabling convenient replacement of templates with different die hole diameters to meet the requirements of fertilizer granulation with different particle sizes.

[0010] Furthermore, the bottom corners of the end of the template away from the handle and the top corners of the extrusion cylinder are both designed with chamfers.

[0011] By adopting the above technical solution, the difficulty of installing the template is effectively reduced, and it is more convenient for the user to replace the template.

[0012] Furthermore, the positioning cylinder is only installed at the top of a group of extrusion cylinders at the bottom of the end of the template away from the handle, and the diameter of the positioning cylinder is smaller than that of the extrusion cylinder.

[0013] By adopting the above technical solution, the extrusion cylinder only squeezes and fixes the template and does not enter the positioning hole.

[0014] Furthermore, the top corners of the positioning cylinder and the bottom corners of the positioning hole are both designed with chamfers, and the positioning cylinder is slidably connected to a positioning rod fixedly installed inside the machine body.

[0015] By adopting the above technical solution, the difficulty of the positioning cylinder entering the positioning hole is effectively reduced.

[0016] Furthermore, a through groove corresponding to the positioning rod is penetrated at the end of the template where the positioning hole is opened, and the end opening corners of the through groove are both designed with chamfers, and the width of the through groove is smaller than the diameter of the positioning cylinder.

[0017] By adopting the above technical solution, the setting of the positioning rod is prevented from affecting the normal sliding of the template.

[0018] Furthermore, the connecting frame is designed in an overall "mouth" shape, and the connecting frame is fixedly connected to multiple groups of extrusion cylinders.

[0019] By adopting the above technical solution, it is ensured that multiple groups of extrusion cylinders will perform lifting and lowering movements synchronously.

[0020] Furthermore, the driver includes a pedal slidably installed inside the machine body. The end of the pedal is fixedly connected to the connecting frame. The bottom of the pedal is located outside the machine body, and the cross-section of the pedal is designed in an L shape.

[0021] By adopting the above technical solution, stepping on the pedal downward will enable the connecting frame to obtain the power to slide downward.

[0022] In summary, the present invention has the following beneficial effects:

[0023] The template in the utility model is installed through a mounting rail and has a handle at the end, which can be pulled from the outside of the machine body for replacement without opening the machine cabin, reducing the difficulty of template replacement and improving usage efficiency. Templates with different die hole diameters can be easily replaced to meet the fertilizer granulation needs of different particle sizes. The extrusion cylinder is attached to the outer wall of the template under the action of the spring, giving thrust to the bottom of the template to improve the fixation of the template in the mounting rail; at the same time, the positioning cylinder cooperates with the positioning hole on the template to further fix the position of the template, and the oblique angle design of the positioning cylinder and the positioning hole and the sliding connection with the positioning rod ensure the accuracy and stability of positioning. The pedal design of the driver is convenient for operation. By stepping on the pedal, the connecting frame can drive the extrusion cylinder to move, and the extrusion cylinder and the template can be separated, which is convenient for template replacement. In the process of installing the template, even if there are no auxiliary personnel, the oblique angle design of the template and the extrusion cylinder can be used to complete the installation, and the template has good stability after installation.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] A granulator with adjustable particle size, such as Figure 1 - Figure 5 As shown, it includes a body 1, an extrusion mechanism 2, a template 3 and a cutting assembly 5;

[0033] In this embodiment, a template 3 is slidably mounted within the body 1. A mounting track 4 corresponding to the template 3 is provided on the body 1. When a template 3 with a die hole of a different diameter needs to be replaced, it can be removed from the mounting track 4 for replacement. Furthermore, a handle 31 located on the outside of the body 1 is installed at the end of the template 3. Since the handle 31 is located on the outside of the body 1, the user can pull the handle 31 from the outside of the body 1 to pull the template 3 out of the body 1, thereby reducing the difficulty of replacing the template 3.

[0034] At the same time, in this embodiment, multiple groups of extrusion cylinders 6 corresponding to the templates 3 are installed in the machine body 1, and springs 8 connected to the extrusion cylinders 6 are installed in the machine body 1. During the installation of the template 3, the extrusion cylinder 6 will move downward, so that the spring 8 will be squeezed by the extrusion cylinder 6 and be in a compressed state. When the template 3 is installed, the top of the extrusion cylinder 6 will be in contact with the outer wall of the bottom of the template 3 under the action of the spring 8, but the extrusion cylinder 6 is not completely reset, so that it will continue to give thrust to the bottom of the template 3 under the action of the spring 8, thereby improving the fixity of the position of the template 3 in the installation track 4;

[0035] For example, a positioning cylinder 9 is fixedly installed on the top of a group of extrusion cylinders 6, and a positioning hole 10 corresponding to the positioning cylinder 9 is opened on the template 3. When the position of the positioning cylinder 9 corresponds to the position of the positioning hole 10, the positioning cylinder 9 will enter the positioning hole 10 under the action of the thrust given by the extrusion cylinder 6, so that after the template 3 is installed, the positioning cylinder 9 will be located in the positioning hole 10, thereby further fixing the position of the template 3;

[0036] It should be noted that in this embodiment, the bottom corners of the end of the template 3 away from the handle 31 and the top corners of the extrusion cylinder 6 are both designed with bevels, which greatly reduces the difficulty of the template 3 entering the installation track 4. At the same time, when the template 3 slides into the installation track 4, the bevel at its end will squeeze the bevel of the extrusion cylinder 6, forcing the extrusion cylinder 6 to slide downward, thereby reducing the difficulty of installing the template 3.

[0037] Because the positioning cylinder 9 in this embodiment is only installed on the top of a group of extrusion cylinders 6 at the bottom of the end of the template 3 away from the handle 31, the positioning hole 10 is also only opened at the end of the template 3 away from the handle 31. Therefore, after the template 3 is pushed into the mounting track 4, the positioning cylinder 9 will not be installed on the first group of extrusion cylinders 6. Because the diameter of the positioning cylinder 9 is smaller than the diameter of the extrusion cylinder 6, the first group of extrusion cylinders 6 will not enter the positioning hole 10, ensuring that the positioning cylinder 9 will fix the template 3 only after the template 3 is completely entered into the mounting track 4.

[0038] It should also be noted that the top corners of the positioning cylinder 9 and the bottom corners of the positioning hole 10 in this embodiment are both beveled. When the positioning cylinder 9 enters the positioning hole 10, the bevel of its top will guide the bevel of the positioning hole 10 to reduce the difficulty of the positioning cylinder 9 entering the positioning hole 10. Because the positioning cylinder 9 is slidably connected to the positioning rod 7 fixedly installed in the body 1, the sliding of the positioning cylinder 9 and the extrusion cylinder 6 will be restricted by the positioning rod 7, further ensuring the sliding stability of the positioning cylinder 9 and the extrusion cylinder 6.

[0039] At the same time, a through groove 11 corresponding to the positioning rod 7 is provided at the end of the positioning hole 10 in the template 3, so that the setting of the positioning rod 7 will not affect the normal sliding of the template 3, and the width of the through groove 11 is smaller than the diameter of the positioning tube 9, so that the setting of the through groove 11 will not affect the cooperation between the positioning hole 10 and the positioning tube 9. At the same time, the end opening corners of the through groove 11 are all beveled. This design can ensure that the template 3 can pass through the positioning rod 7 smoothly.

[0040] In this embodiment, a connecting frame 12 connected to the extrusion cylinder 6 is also slidably installed in the body 1. At the same time, the connecting frame 12 is designed in the shape of a "mouth". The connecting frame 12 is fixedly connected to the multiple groups of extrusion cylinders 6, so that the connecting frame 12 will drive the multiple groups of extrusion cylinders 6 to move synchronously, ensuring that the multiple groups of extrusion cylinders 6 will perform synchronous lifting and lowering movements. At the same time, a driver for driving the connecting frame 12 is also provided in the body 1;

[0041] In some examples, the drive includes a pedal 13 slidably installed in the body 1, and the top of the pedal 13 is fixedly connected to the connecting frame 12. Because the bottom of the pedal 13 is located on the outside of the body 1 and the cross-section of the pedal 13 is L-shaped, when the user needs to contact the restriction imposed on the template 3 by the extrusion cylinder 6, stepping on the pedal 13 downward will enable the connecting frame 12 to obtain the power to slide downward.

[0042] The working principle of the utility model is as follows: when feed needs to be granulated, first, the raw material is placed into the machine body 1, and then the extrusion mechanism 2 and the cutting component 5 are started to make the raw material pass through the die hole of the template 3, and at the same time the cutting component 5 cuts the raw material passing through to make it into feed pellets;

[0043] When the required feed particle size changes and the template 3 with a different aperture needs to be replaced, the pedal 13 is first pressed downward to make the connecting frame 12 drive the multiple groups of extrusion cylinders 6 to start moving downward, thereby separating the extrusion cylinders 6 from the template 3. As the extrusion cylinders 6 move downward, they squeeze the spring 8, and at the same time, the extrusion cylinders 6 also drive the positioning cylinders 9 to slide downward synchronously, causing the positioning cylinders 9 to separate from the positioning holes 10. At this time, the user can pull the handle 31 to pull the template 3 out of the mounting track 4, and then push the template 3 with the corresponding aperture back into the mounting track 4;

[0044] During this process, when the template 3 is not installed, the distance between its handle 31 and the mounting rail 4 is large, and a single person cannot step on the pedal 13. At this time, if a second user steps on the pedal 13, the template 3 can be directly pushed completely into the mounting rail 4. Then, the pedal 13 is released, and the multiple sets of springs 8 will push the extrusion cylinder 6 upward to fix the template 3. At the same time, the positioning cylinder 9 will also enter the positioning hole 10 to further fix the template 3.

[0045] During the installation of the template 3, if there is no second user to assist in stepping on the pedal 13, the template 3 can be directly pushed into the installation track 4, so that the oblique angle of the template 3 will squeeze the oblique angle of the first set of extrusion cylinders 6, forcing the extrusion cylinders 6 to slide downward, and then continue to push the template 3 until the end of the template 3 contacts the end of the positioning cylinder 9. At this time, the user can step on the pedal 13 and then install the template 3 in the above manner;

[0046] The bottom of the template 3 after installation will be subject to the thrust given by the extrusion cylinder 6, and will also be restricted by the positioning cylinder 9 and the positioning hole 10, effectively ensuring the stability of the template 3 after installation.

[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
