Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer processing technology, specifically a drying device for compound fertilizer processing. Background Technology

[0002] Compound fertilizer, also known as compound fertilizer, refers to chemical fertilizer containing two or more of the following nutrients: nitrogen, phosphorus, and potassium. Compound fertilizer has the advantages of high nutrient content, few by-products, and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. Currently, the processing of compound fertilizer requires the use of drying equipment to dry it in order to extend its shelf life.

[0003] An investigation revealed that a novel compound fertilizer drying device (Publication No.: CN210036037U) is disclosed in a Chinese utility model patent, comprising a working chamber and an auxiliary drying device. The working chamber is arranged from top to bottom as a feeding hopper, a heating chamber, and a storage hopper. The auxiliary drying device includes an air inlet pipe, a heater, an air guide pipe, an exhaust fan, and a feeding pipe. The air inlet pipe is connected to the heating chamber, and the heater is installed on the air inlet pipe. The air inlet end of the air guide pipe is connected to the heating chamber, and the exhaust fan is installed on the air guide pipe. The feeding pipe passes through the heating chamber, and its two ends are connected to the air inlet pipe and the storage hopper, respectively. Preferably, the auxiliary drying device further includes multiple air guide pipes, all located within the feeding hopper and arranged in a row. Any one of the air guide pipes extends in an S-shape from top to bottom and is connected to the air outlet end of the air guide pipe.

[0004] Although the aforementioned patent is more convenient to use and can effectively improve the efficiency of fertilizer drying compared with the prior art, most of the existing compound fertilizer drying equipment still has some problems. For example, during the drying process of compound fertilizer, it is impossible to spread the compound fertilizer out and flat. When the compound fertilizer is piled up in one place, some of the compound fertilizer hidden inside cannot be dried, thereby reducing the drying effect of the compound fertilizer and affecting the drying effect of the entire batch of compound fertilizer.

[0005] Therefore, this utility model provides a drying device for compound fertilizer processing to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This invention utilizes a turntable, connecting rod, slider, connecting shell, leveling roller, and drying fan. When the turntable rotates, the connecting rod, hinged to the turntable, drives the slider, which rotates in conjunction with the turntable, to move back and forth. This causes the slider to move the connecting shell back and forth, prompting the leveling roller, which rotates in conjunction with the connecting shell, to level the compound fertilizer on the support plate inside the box. Simultaneously, the connecting shell drives the drying fan to move synchronously, allowing the drying fan to repeatedly dry the leveled compound fertilizer over a large area. Therefore, this device can spread and level the compound fertilizer during the drying process, preventing it from piling up and causing some hidden parts to remain untreated, thus improving the drying effect and avoiding affecting the overall drying efficiency of the batch of compound fertilizer.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a drying device for compound fertilizer processing, such as... Figure 1-5 As shown, the drying equipment for compound fertilizer processing includes a box body 1, a slider 2 is slidably connected inside the box body 1, a turntable 3 is rotatably connected to the outer wall of the box body 1, a motor 4 for driving the turntable 3 to rotate is provided on the outer wall of the box body 1, a connecting rod 5 is hinged to the outer wall of the turntable 3, one end of the connecting rod 5 away from the turntable 3 is hinged to the inside of the slider 2, a connecting shell 6 is fixedly connected to the outer wall of the slider 2, a leveling roller 7 is rotatably connected inside the connecting shell 6, and a drying mechanism is provided on the outer wall of the connecting shell 6;

[0028] The drying mechanism includes a first telescopic rod 8 fixedly connected to the outer wall of the connecting housing 6. A drying fan 9 is fixedly connected to the end of the first telescopic rod 8 away from the connecting housing 6. A first spring 10 is fixedly connected to the outer wall of the connecting housing 6. The end of the first spring 10 away from the connecting housing 6 is fixedly connected to the outer wall of the drying fan 9. The first telescopic rod 8 is inserted through the inner ring of the first spring 10. A bearing plate 17 is hinged to the bottom of the housing 1.

[0029] Specifically, when the compound fertilizer needs to be dried, it is first placed onto the support plate 17 inside the housing 1. Then, the motor 4 is started. When the motor 4 is running, the internal output shaft drives the turntable 3 to rotate. As the turntable 3 rotates, the connecting rod 5, which is hinged to the turntable 3, swings. During the swinging of the connecting rod 5, the slider 2, which is hinged to the connecting rod 5, drives the connecting outer shell 6 to move back and forth. This causes the leveling roller 7, which is coordinated with the rotation of the connecting outer shell 6, to roll when it comes into contact with the support plate 17. This rolling leveling roller 7 flattens the compound fertilizer on the support plate 17, ensuring that the compound fertilizer is flattened, which improves the overall drying effect. The connecting outer shell 6 can also drive the drying fan. The synchronous movement of the drying fan 9 allows the flattened compound fertilizer to be repeatedly dried over a large area while moving back and forth. This ensures efficient drying of the compound fertilizer and prevents some of the compound fertilizer hidden in the pile from being dried, which would affect the drying effect of the entire batch of compound fertilizer. At the same time, when the drying fan 9 moves first to contact the inner wall of the box 1, it can be compressed by the elastic force provided by the first telescopic rod 8 and the first spring 10. This prevents the slider 2 from being blocked from moving further due to the initial contact between the drying fan 9 and the inner wall of the box 1 before it has moved to a certain position driven by the connecting rod 5. This avoids motion interference problems for the slider 2 and ensures that the slider 2 can smoothly complete the entire back-and-forth movement process.

[0030] A base 11 is provided at the bottom of the housing 1, and a connecting block 12 is fixedly connected to the top of the base 11.

[0031] The outer wall of the housing 1 is rotatably connected to a cam 13 that contacts the connecting block 12, and a transmission belt 14 is connected between the cam 13 and the turntable 3.

[0032] A second telescopic rod 15 is fixedly connected to the top of the base 11, and the end of the second telescopic rod 15 away from the base 11 is fixedly connected to the bottom of the box 1.

[0033] A second spring 16 is fixedly connected to the top of the base 11. The end of the second spring 16 away from the base 11 is fixedly connected to the bottom of the box 1. The second telescopic rod 15 is inserted through the inner ring of the second spring 16.

[0034] The outer wall of the housing 1 has a through hole 19 for the slider 2 to slide.

[0035] Specifically, when the turntable 3 rotates, the transmission belt 14, which is in cooperation with the turntable 3, drives the cam 13 to rotate synchronously. Each time the cam 13 rotates to contact the connecting block 12, the cam 13 is blocked by the connecting block 12 and uses the arc-shaped cooperation between them to move the box 1 upward. When the cam 13 is repeatedly pushed up by the connecting block 12 and not in contact, the box 1 can achieve the effect of vibration by the elastic force of the second telescopic rod 15 and the second spring 16. This is to achieve the purpose of vibrating and spreading the compound fertilizer on the bearing plate 17, further improving the heating effect of the compound fertilizer, and ensuring that the compound fertilizer will not affect the subsequent processing due to the drying process. In addition, the through hole 19 allows the slider 2 to have room to move, ensuring that when the slider 2 is driven by the connecting rod 5, it can drive the connecting shell 6 to move back and forth.

[0036] A third spring 18 is fixedly connected to the outer wall of the housing 1, and the end of the third spring 18 away from the housing 1 is fixedly connected to the outer wall of the bearing plate 17.

[0037] Specifically, when the dried compound fertilizer needs to be unloaded, the support plate 17 can be pushed down, so that the support plate 17 can tilt to form an opening for unloading the compound fertilizer by means of the hinge between the support plate 17 and the box body 1. When the compound fertilizer is still drying, the elastic force provided by the third spring 18 makes the connection between the support plate 17 and the box body 1 have good toughness. The elastic force of the third spring 18 makes the support plate 17 always fit and seal with the bottom of the box body 1, preventing the compound fertilizer from falling down through the support plate 17 while the drying process is still in progress. Thus, the third spring 18 makes it easy to unload the compound fertilizer while preventing the compound fertilizer from being unloaded randomly.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
