Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilization technology, and in particular to a fertilization device for improving nitrogen fertilizer utilization. Background Technology
[0002] Fertilization is the process of adding fertilizer to the soil to replenish the nutrients in the soil, promote crop growth and increase yield. Fertilizer can be organic (such as well-rotted farmyard manure, compost, etc.) or inorganic (such as chemical fertilizer, compound fertilizer, etc.). The purpose of fertilization is to provide the main nutrients needed by crops, especially elements such as nitrogen, phosphorus and potassium, and help the soil restore or maintain its fertility.
[0003] Chinese patent discloses a device for improving the utilization rate of phosphate fertilizer (authorization announcement number CN220986502U). This patented technology uses a pressing block that moves up and down continuously, and a worker moves the base by pushing a rod. This allows the equipment to fully contact and compact the fertilizer and soil within the area. Compared with the traditional method of compacting the ground in a small area, this equipment can effectively increase the speed of compaction of fertilizer and soil within the area, reduce the labor burden of workers, ensure full contact between fertilizer and soil, and because the equipment is compact in design, it can be used in various small areas, thus improving the overall practicality of the equipment.
[0004] However, most existing fertilizer application methods involve compacting the fertilizer into contact with the soil. This often results in fertilizer accumulation after application, affecting fertilizer utilization. For example, the aforementioned comparative document uses a method of directly compacting the fertilizer with the soil. In practical applications, fertilizer accumulates when applied to the soil, and compacting this accumulation leads to poor fertilizer utilization and low practicality. Therefore, those skilled in the art provide a fertilization device to improve nitrogen fertilizer utilization and address the problems mentioned in the background art. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a fertilization device that improves nitrogen fertilizer utilization, thus solving the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fertilization device for improving nitrogen fertilizer utilization, comprising: a trolley, a fertilizer box mounted on the upper surface of the trolley, a feed inlet on the upper surface of the fertilizer box, a discharge plate disposed inside the feed inlet, a first motor mounted on the front surface of the fertilizer box, a grinding roller connected to the drive end of the first motor above the discharge plate, a discharge frame integrally mounted on the lower surface of the fertilizer box, a second motor mounted on the front surface of the discharge frame, a lifting plate disposed below the trolley, guide rods symmetrically disposed on the upper surface of the lifting plate, a scraper plate disposed on the lower surface of the lifting plate, a connecting plate disposed on one side of the lifting plate, and a compaction plate disposed below the connecting plate.
[0007] As a further technical solution of this utility model, two second electric lifting rods are symmetrically installed on the upper surface of the connecting plate, and the telescopic ends of the second electric lifting rods are connected to the upper surface of the compaction plate.
[0008] As a further technical solution of this utility model, the upper end of the guide rod penetrates the upper surface of the trolley, and a positioning nut is threadedly connected to the outside of the guide rod above the trolley.
[0009] As a further technical solution of this utility model, a first electric lifting rod is installed on one side of the fertilizer box on the upper surface of the trolley, and the telescopic end of the first electric lifting rod is connected to the middle position of the upper surface of the lifting plate.
[0010] As a further technical solution of this utility model, the drive end of the second motor is connected to a rotating shaft inside the discharge frame, and the rotating shaft is symmetrically provided with baffles on the outside.
[0011] As a further technical solution of this utility model, the feeding plate is inclined inside the fertilizer box, and there is a gap between the outside of the grinding roller and the feeding plate.
[0012] This invention provides a fertilization device that improves nitrogen fertilizer utilization, and has the following advantages compared with the prior art:
[0013] 1. This design is a fertilization device for improving nitrogen fertilizer utilization. The nitrogen fertilizer is tilted and fed into the fertilizer box from the feed inlet by the feeding plate. The operation of the first motor causes the grinding roller to rotate, which can crush the nitrogen fertilizer and prevent it from clumping and affecting the subsequent nitrogen fertilizer discharge and fertilization. At the same time, the operation of the second motor causes the deflector plate outside the rotating shaft to rotate and push the nitrogen fertilizer to feed, which can effectively prevent blockage. It has good practicality.
[0014] 2. This design provides a fertilization device to improve nitrogen fertilizer utilization. The operation of the first electric lifting rod causes the lifting plate to rise and fall, thereby adjusting the height of the scraper plate to scrape the nitrogen fertilizer after application, preventing it from piling up and affecting the utilization rate of nitrogen fertilizer. The compaction plate can compact the nitrogen fertilizer, thereby improving the contact between nitrogen fertilizer and soil and increasing the utilization rate of nitrogen fertilizer. It has good practicality. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4This utility model provides a fertilization device solution for improving nitrogen fertilizer utilization: It includes a trolley 1, a fertilizer box 2 mounted on the upper surface of the trolley 1, a feed inlet 22 on the upper surface of the fertilizer box 2, a discharge plate 21 inside the feed inlet 22, a first motor 24 mounted on the front surface of the fertilizer box 2, a grinding roller 241 connected above the discharge plate 21 to the drive end of the first motor 24, a discharge frame 23 integrally mounted on the lower surface of the fertilizer box 2, a second motor 25 mounted on the front surface of the discharge frame 23, and a lifting plate below the trolley 1. 3. Guide rods 33 are symmetrically arranged on the upper surface of the lifting plate 3, and a scraper plate 31 is installed on the lower surface of the lifting plate 3. A connecting plate 34 is installed on one side of the lifting plate 3, and a compaction plate 341 is arranged below the connecting plate 34. This arrangement allows nitrogen fertilizer to enter the fertilizer box 2 from the feed inlet 22 and then be discharged through the discharge plate 21. During the discharge, the nitrogen fertilizer can be crushed by the grinding roller 241, thereby avoiding subsequent discharge. At the same time, the scraper plate 31 can be used to scrape the nitrogen fertilizer after fertilization to prevent accumulation and affect the utilization rate of nitrogen fertilizer.
[0022] like Figure 2 As shown, two second electric lifting rods 342 are symmetrically installed on the upper surface of the connecting plate 34. The telescopic ends of the second electric lifting rods 342 are connected to the upper surface of the compaction plate 341. This arrangement utilizes the synchronous operation of the two second electric lifting rods 342, which causes the compaction plate 341 to rise and fall below the connecting plate 34. Thus, the compaction plate 341 can compact the leveled fertilizer in contact with the soil, thereby improving the utilization rate of nitrogen fertilizer.
[0023] like Figure 1 and Figure 2 As shown, the upper end of the guide rod 33 penetrates the upper surface of the trolley 1, and a positioning nut 331 is threadedly connected to the outside of the guide rod 33 above the trolley 1. A first electric lifting rod 32 is installed on one side of the fertilizer box 2 on the upper surface of the trolley 1. The telescopic end of the first electric lifting rod 32 is connected to the middle position of the upper surface of the lifting plate 3. This setting allows the lifting plate 3 to be raised and lowered by the operation of the first electric lifting rod 32, thereby adjusting the position of the scraper plate 31, and locking it with the positioning nut 331 to ensure the stability of the scraper plate 31.
[0024] like Figure 3 and Figure 4 As shown, the drive end of the second motor 25 is connected to a rotating shaft 251 inside the discharge frame 23. A paddle plate 252 is symmetrically arranged outside the rotating shaft 251. This arrangement uses the operation of the second motor 25 to make the rotating shaft 251 rotate in the discharge frame 23, and when it rotates, it will make the paddle plate 252 rotate to paddle and discharge the nitrogen fertilizer inside the fertilizer box 2, effectively preventing blockage.
[0025] like Figure 4As shown, the feeding plate 21 is inclined inside the fertilizer box 2, and there is a gap between the outside of the grinding roller 241 and the feeding plate 21. This arrangement will cause the grinding roller 241 to rotate above the feeding plate 21 when the first motor 24 is working. When rotating, the nitrogen fertilizer fed on and off the feeding plate 21 can be crushed to prevent the nitrogen fertilizer from clumping and affecting subsequent fertilization.
[0026] The working principle of this utility model is as follows: When using the fertilization device for improving nitrogen fertilizer utilization, nitrogen fertilizer is first fed into the fertilizer box 2 through the inlet 22. Upon entry, the nitrogen fertilizer passes through the discharge plate 21 into the fertilizer box 2. Simultaneously, the first motor 24 is activated, causing the grinding roller 241 to rotate. This rotation crushes the fed nitrogen fertilizer, preventing clumping and ensuring proper fertilization. During fertilization, the operator can move the trolley 1. The first electric lifting rod 32 raises and lowers the lifting plate 3, thereby adjusting the scraper plate 3. Position 1 and lock it with positioning nut 331 to ensure the stability of the scraper plate 31. During fertilization, the operation of the second motor 25 will cause the rotating shaft 251 to rotate in the discharge frame 23. When rotating, the paddle plate 252 will rotate to paddle and discharge the nitrogen fertilizer inside the fertilizer box 2. During discharge, the scraper plate 31 on the lower surface of the lifting plate 3 can scrape the nitrogen fertilizer. When scraping, the synchronous operation of the two second electric lifting rods 342 will cause the compaction plate 341 to rise and fall below the connecting plate 34. Thus, the compaction plate 341 can compact the scraped fertilizer in contact with the soil, thereby improving the utilization rate of nitrogen fertilizer.
[0027] The first electric lifting rod, the second electric lifting rod, the first motor, and the second motor used in this utility model are all existing known electrical devices. They all have a main controller and power supply connection installed on the trolley and can all be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. The appropriate model is selected according to the actual use. Therefore, the structure, circuit, and control principle of the device will not be described in detail here.
[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
