Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fertilizer production, in particular to a crushing mixer for organic fertilizer production. Background Art
[0002] Organic fertilizer refers to a type of fertilizer that contains organic matter and can provide a variety of inorganic and organic nutrients for crops, as well as fertilize and improve the soil. It comes from a wide range of sources, including plant and animal residues (such as straw, animal manure, etc.), compost, green manure, etc. Organic fertilizer is rich in organic matter, which can improve soil structure, enhance the soil's ability to retain water and fertilizer, and make the soil more loose and breathable. At the same time, it can slowly release nutrients, providing long-term and stable nutrition for crops, which is beneficial to improving the quality of agricultural products. Moreover, the use of organic fertilizers can also promote the reproduction of soil microorganisms, which can further decompose fertilizers, making nutrients easier for plants to absorb.
[0003] Currently, there are some areas in the organic fertilizer production process that could be optimized. Before leaving the factory, some organic fertilizers must be dried and then bagged for shipment. This process typically involves using a crushing device to break up the fertilizer. However, in reality, even after drying, some organic fertilizers, even though they meet packaging requirements, are still fed into the crusher. This practice undoubtedly wastes electricity and unnecessary time, thereby reducing overall production efficiency. Utility Model Content
[0004] In order to solve the above problems, the utility model proposes a crushing mixer for organic fertilizer production, which can pre-screen the organic fertilizer before crushing and re-mix the materials after crushing.
[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is as follows: a crushing mixer for organic fertilizer production, comprising a frame, wherein both sides of the interior of the frame are divided into a screening area and a crushing area by baffles, and a feed guide plate is provided at the upper end of the screening area away from the crushing area, and a plurality of feed rollers are rotatably connected in the screening area, and the feed rollers are driven by a motor 1 fixed to the side wall of the frame, and a screening gap is provided between the feed rollers, and two crushing rollers that cooperate with each other are rotatably connected in the crushing area, and the crushing rollers are driven by a motor 2 fixed to the side wall of the frame, and a discharging guide plate is hinged at the lower end of the interior of the frame, and the end of the discharging guide plate extends to one side of the frame, and a discharging port is provided between the discharging guide plate and the side wall of the frame, a discharging through groove is formed between the baffle and the discharging guide plate, and a vibrator for driving the discharging guide plate is provided under the frame.
[0006] Furthermore, the upper end of the baffle is an inclined surface.
[0007] Based on these features, the sloped design allows fertilizer to slide more smoothly from the screening area to the crushing area, reducing fertilizer accumulation and blockage at the baffle, thereby improving the overall operating efficiency of the equipment. At the same time, the slope also helps guide the fertilizer accurately into the crushing area, ensuring the continuity of the crushing process.
[0008] Furthermore, the feed guide plate is an arc-shaped plate bent away from the crushing zone.
[0009] Based on the above characteristics, the feed guide plate of the curved plate can better guide the fertilizer into the screening area, reduce the splashing and overflow of the fertilizer at the feed port, and also provide a buffer for the fertilizer when entering the screening area, avoiding the fertilizer from directly impacting the feed roller, playing a certain protective role on the feed roller and extending its service life.
[0010] Furthermore, the feed rollers are arranged obliquely, the height of the feed rollers close to the crushing zone is lower than the height of the feed rollers far from the crushing zone, and a plurality of anti-slip protrusions are provided on the side walls of the feed rollers.
[0011] Based on these features, the diagonal arrangement and height difference design allow the fertilizer to flow naturally to the crushing area under the action of the feed rollers, eliminating the need for additional power devices and saving energy. The anti-slip bumps increase the friction between the feed rollers and the fertilizer, preventing the fertilizer from slipping during feeding and ensuring stable and accurate feeding.
[0012] Furthermore, the feeding roller and the crushing roller are located at the upper ends of the screening area and the crushing area respectively, and the height of the feeding roller is higher than that of the crushing roller.
[0013] Based on the above characteristics, the feed roller and crushing roller are respectively arranged at the upper end of the inner area, which is conducive to fully utilizing the space. The height of the feed roller is higher than that of the crushing roller, which facilitates the smooth drop of fertilizer from the feed roller into the crushing roller for crushing, ensuring the flow order of fertilizer and improving crushing efficiency.
[0014] Furthermore, the two crushing rollers rotate synchronously relative to each other under the drive of motor 2.
[0015] Based on the above characteristics, the synchronously relatively rotating crushing rollers can evenly squeeze and crush the fertilizer, ensuring the consistency of the crushing effect.
[0016] Furthermore, the discharging guide plate is arranged at an angle, a fixing plate is symmetrically fixed below the frame, and the top of the fixing plate is connected to the lower wall of the discharging guide plate through a spring.
[0017] Based on these features, the inclined discharge guide plate allows crushed fertilizer to be discharged quickly from the discharge port, preventing fertilizer accumulation within the equipment. The spring connection design allows the discharge guide plate to generate a certain degree of elastic vibration under the action of the vibrator, which helps to smoothly discharge the fertilizer, prevents the discharge port from clogging, and improves discharge efficiency.
[0018] Compared with the existing technology, the advantages of the present invention are as follows: the screening area and the crushing area are separated by a baffle, the organic fertilizer first enters the screening area and is screened through the screening gap between the feed rollers, and the smaller particles that meet the requirements can be screened out before crushing, preventing these particles from entering the crushing area, thereby improving the working efficiency of the crushing rollers and reducing unnecessary energy consumption. The two mutually coordinated crushing rollers rotate under the drive of motor 2, fully crushing the pre-screened fertilizer to ensure that the fertilizer particles are uniform in size. The crushed fertilizer falls on the discharge guide plate. During the discharge process, due to the action of the vibrator, the discharge guide plate vibrates continuously, so that the crushed fertilizer passes through the discharge chute and is mixed with the pre-screened fertilizer particles and discharged through the discharge port.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.
[0026] Combined with attachment Figure 1 , Attachment Figure 5A crushing and mixing machine for organic fertilizer production includes a frame 1, with baffles 2 separating the two sides of the frame 1 into a screening area and a crushing area. The baffles 2 have an inclined top. This design allows fertilizer to slide smoothly from the screening area to the crushing area, reducing fertilizer accumulation and blockage at the baffles 2 and improving the overall operating efficiency of the equipment. The inclined surface also helps guide fertilizer accurately into the crushing area, ensuring the continuity of the crushing process.
[0027] Combined with attachment Figure 5 A feed guide plate 3 is provided on the upper end of the screening area away from the crushing area. The feed guide plate 3 is an arc-shaped plate bent back to the crushing area. The arc-shaped feed guide plate 3 can better guide the fertilizer into the screening area, reduce the splashing and overflow of the fertilizer at the feed port, and also provide a buffer for the fertilizer when entering the screening area, avoiding the fertilizer from directly impacting the feed roller 4, playing a certain protective role on the feed roller 4, and extending its service life.
[0028] Combined with attachment Figure 1 , Attachment Figure 4 , Attachment Figure 5 The screening area is provided with a plurality of feed rollers 4 that are rotatably connected. The feed rollers 4 are driven by a motor 5 fixed to the side wall of the frame 1. Screening gaps are provided between the feed rollers 4. The feed rollers 4 are arranged diagonally, with the feed rollers 4 near the crushing area being lower than those far from the crushing area. This diagonal arrangement and height difference allows the fertilizer to flow naturally toward the crushing area under the action of the feed rollers 4, eliminating the need for additional power devices and saving energy. The side walls of the feed rollers 4 are provided with a plurality of anti-skid protrusions 10. The anti-skid protrusions 10 increase the friction between the feed rollers 4 and the fertilizer, preventing the fertilizer from slipping during feeding and ensuring stable and accurate feeding.
[0029] Combined with attachment Figure 1 , Attachment Figure 5 Two mutually cooperating crushing rollers 6 are rotatably connected within the crushing zone. The feed roller 4 and crushing roller 6 are located at the upper ends of the screening zone and crushing zone, respectively, facilitating full utilization of space. Furthermore, the feed roller 4 is higher than the crushing roller 6, facilitating smooth passage of fertilizer from the feed roller 4 into the crushing roller 6 for crushing, ensuring the proper flow of fertilizer and improving crushing efficiency.
[0030] Combined with attachment Figure 1 The crushing roller 6 is driven by a motor 2 7 fixed on the side wall of the frame 1. The two crushing rollers 6 rotate synchronously relative to each other under the drive of the motor 2 7, which can evenly squeeze and crush the fertilizer to ensure the consistency of the crushing effect.
[0031] Combined with attachment Figure 2 , Attachment Figure 3 , Attachment Figure 5A discharge guide plate 8 is hingedly provided at the lower end of the frame 1. The end of the discharge guide plate 8 extends to one side of the frame 1, and a discharge port is provided between the discharge guide plate 8 and the side wall of the frame 1. A discharge channel is formed between the baffle 2 and the discharge guide plate 8. A vibrator 9 for driving the discharge guide plate 8 is provided below the frame 1. The discharge guide plate 8 is tilted so that the crushed fertilizer can be quickly discharged from the discharge port to avoid accumulation of fertilizer in the equipment. A fixed plate 11 is symmetrically fixed below the frame 1. The upper part of the fixed plate 11 is connected to the lower wall of the discharge guide plate 8 by a spring 12. The design of the spring 12 connection can make the discharge guide plate 8 produce a certain elastic vibration under the action of the vibrator 9, which helps to discharge the fertilizer smoothly, prevent the discharge port from being blocked, and improve the discharge efficiency.
[0032] The specific embodiment of the present invention is as follows: Connect the machine to an external power source, turn on motors 1 (5), 2 (7), and 9, and feed the organic fertilizer raw material to be processed through the feed guide plate (3). The feed guide plate (3) effectively guides the fertilizer into the screening area. Once in the screening area, motor 1 (5) drives the feed rollers (4) to rotate. Driven by the feed rollers (4), the fertilizer moves toward the crushing area, utilizing the height difference between the feed rollers (4). The screening gaps between the feed rollers (4) simultaneously screen the fertilizer, allowing smaller fertilizer particles to fall through the gaps and onto the discharge guide plate (8). Larger fertilizer particles enter the crushing area, where two crushing rollers (6) rotate synchronously with each other, driven by motor 2 (7), effectively crushing the fertilizer. The crushed fertilizer falls onto the discharge guide plate (8). The discharge guide plate (8) is tilted and vibrates under the action of the vibrator (9) below the frame (1) and the elastic support of the spring (12) above the fixed plate (11). This causes the crushed fertilizer to mix with the pre-screened fertilizer and quickly discharge from the discharge port, completing the crushing and mixing of the organic fertilizer.
[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meaning of the above terms in the present invention can be understood according to specific circumstances.
[0034] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
