Description

Technical Field

[0001] This utility model relates to the field of fertilizer production equipment technology, specifically to a feeder for fertilizer production, suitable for conveying granules such as bio-fertilizers and compound fertilizers. Background Technology

[0002] During fertilizer production, raw materials are conveyed to the hopper via a belt conveyor and a distributor. Existing fertilizer distributors use a herringbone structure, switching the chute discharge via rotating flaps. However, due to the humid environment, fertilizer is prone to deliquescence and clumping. Long-term contact with the chute sidewalls or flaps can leave clumps, easily causing problems such as flaps getting stuck or failing to reach the correct position. This necessitates manual knocking or disassembly to remove the clumps, resulting in low processing efficiency and risks associated with working at height. Traditional solutions, such as periodic vibration or airflow purging, suffer from complex structures, high energy consumption, or poor adaptability. Utility Model Content

[0003] To address the aforementioned shortcomings, this invention aims to provide a fertilizer distributor for fertilizer production. This invention achieves improved production efficiency and reduced maintenance frequency by optimizing the chute structure, intelligently linking the distributing plate and vibrating motor, and integrating cleaning components.

[0004] To achieve the above technical objectives, the following technical solutions were adopted:

[0005] A fertilizer production distributor includes two symmetrically arranged herringbone chutes, a distributing plate, a cleaning assembly, and a vibrating motor. Each chute has an inlet connected to a belt conveyor at its top and a hopper at its bottom. Each chute contains a distributing plate to control the fertilizer flow direction. Cleaning assemblies are symmetrically installed on both sides of the bottom of the distributing plate. Each cleaning assembly includes an L-shaped support arm and multiple cleaning heads, with the support arm movably connected to the cleaning heads. The cleaning heads are inclined towards the chute inlet. The vibrating motor is located on the outside of each chute and is linked to the distributing plate for control.

[0006] Furthermore, the cleaning head is movably connected to the support arm via a spring clamping mechanism to ensure that it is in close contact with the chute wall.

[0007] Furthermore, the cleaning heads are inclined at 45° toward the chute feed inlet, and there are three of them, located at the upper, middle and lower positions of the main shaft of the support arm in sequence.

[0008] Furthermore, the cleaning head is an elastic scraper made of polyurethane material, which can compensate for the unevenness of the chute wall through its own deformation, while avoiding damage to the wall.

[0009] Furthermore, the working surface of the elastic scraper is wavy, which creates an alternating contact area between the scraper and the chute wall, thereby improving the breakup rate of agglomerates.

[0010] Furthermore, the cleaning head is a nylon brush that removes residual particles.

[0011] Furthermore, the vibration motor monitors the movement trajectory of the material distribution plate via a position sensor arranged parallel to the outside of the material distribution plate guide rail, and controls its own switching.

[0012] Furthermore, the material distribution plate is made of high-strength wear-resistant steel plate and is driven by a hydraulic cylinder. Its size can completely cover the chute to ensure a complete seal.

[0013] Furthermore, the chute has an inclination angle of 70° to 75° and an anti-stick coating on its inner wall.

[0014] The beneficial effects achieved by this utility model are as follows:

[0015] Compared with existing technologies, this utility model provides a fertilizer distributor for preventing chute agglomeration in fertilizer production. By optimizing the structure of the distributor and replacing the traditional rotary flap design, it uses left and right insert plates to control the material feeding target, reducing the agglomeration rate of the insert plates and thus reducing maintenance frequency. Simultaneously, the increased chute inclination angle prevents fertilizer from accumulating and agglomerating on the chute walls. A cleaning component is integrated at the bottom of the insert plates, driving the cleaning component to scrape the chute walls as the insert plates move, achieving zero-power cleaning. Furthermore, a vibration motor is located on the outside of the chute. With the aid of a position sensor, when the feeding target is switched, as one side of the insert plate moves open, the other side begins to close, and the vibration motor on the closed side begins to vibrate, loosening and dislodging any agglomerates adhering to the chute, reducing additional cleaning time. Therefore, this utility model has the advantages of simple structure, low energy consumption, low maintenance cost, and high processing efficiency. Attached Figure Description

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. The described embodiments are merely some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 3 As shown, the present invention provides a fertilizer distributor for preventing caking in chutes, comprising two chute 1s symmetrically distributed in a herringbone shape, a distributor plate 2 located in each chute 1, a cleaning assembly 3, and a vibration motor 4.

[0026] The two chutes 1 are provided with a feed inlet 11 above them, which is connected to the belt conveyor 7, and are respectively connected to the hoppers 6 below them; the chutes 1 are inclined at an angle of 70° to 75° to reduce the accumulation of fertilizer particles, and the inner wall is provided with an anti-stick coating to further reduce the adhesion of the wall surface and reduce agglomeration; each chute 1 is provided with a distribution plate 2 to control the flow direction of fertilizer.

[0027] The material distribution plate 2 is made of high-strength wear-resistant steel plate and is driven by a hydraulic cylinder to completely cover the chute 1, ensuring a complete seal. Cleaning components 3 are symmetrically installed on both sides of its lower bottom.

[0028] The cleaning assembly 3 includes an L-shaped support arm 31 and multiple cleaning heads 32. The support arm 31 is movably connected to the cleaning heads 32 through a spring clamping mechanism 33 to ensure that it is in close contact with the wall of the chute 1. There are three cleaning heads 32, all of which are inclined at 45° toward the feed inlet 11 of the chute 1 and are located at the upper, middle and lower positions of the main shaft of the support arm 31 in sequence.

[0029] The vibration motor 4 is located on the outside of each chute 1. The position sensor 5, which is arranged parallel to the outside of the guide rail of the material distribution plate 2, monitors the movement trajectory of the material distribution plate 2 and controls its own switching. When one side of the material distribution plate 2 moves upward, the other side moves downward. The position sensor 5 on the closed side transmits a signal to the control unit, which then starts the vibration motor 4 outside the chute 1 on that side. After the material distribution plate 2 completely covers the opening of the chute 1, the vibration motor 4 automatically shuts off after a period of delay.

[0030] Example 1: As Figure 4 As shown, the cleaning head 32 in this embodiment is an elastic scraper 321, made of polyurethane material. It can compensate for the unevenness of the chute wall through its own deformation, generate a flexible impact during scraping, avoid damage to the wall and coating of the chute 1, and at the same time have wear resistance and extended service life.

[0031] Example 2: Figure 5 As shown, based on Embodiment 1, the working surface of the elastic scraper 321 in this embodiment is wavy. The wavy contour makes the elastic scraper 321 and the wall of the chute 1 form an alternating contact area, which improves the crushing rate of agglomerates; and the broken material can slide off from the trough, reducing the secondary adhesion of agglomerates to the elastic scraper 321.

[0032] Example 3: Figure 6 As shown, unlike Embodiment 1, the cleaning head 32 in this embodiment is a nylon brush 322. After the elastic scraper 321 scrapes off the clumps attached to the wall, the operator can choose to replace it with the brush 322 for secondary deep cleaning to remove residual particles.

[0033] Its working principle is as follows: During production, fertilizer granules enter the chute 1 of the distributor through the feed inlet 11 via the belt conveyor 7. The hydraulic cylinder drives the distribution plate 2 to move up and down along the guide rail within the chute 1. When the left hopper 6 is selected as the discharge target, the left distribution plate 2 moves upward, opening the left chute 1 and allowing fertilizer to flow into the left hopper 6; the right distribution plate 2 moves downward simultaneously, closing the right chute 1, forming a one-way flow path. When the distribution plates 2 on both sides move, the cleaning components 3 on both sides of their bottom move accordingly. The three 45° inclined cleaning heads 32 (elastic scrapers or nylon brushes) of the cleaning components 3 are pressed tightly against the wall of the chute 1 by the spring clamping mechanism 33, scraping and removing the clumps on both sides of the chute 1 along the 70-75° inclined channel. Simultaneously, as the right-side distribution plate 2 moves downward, the position sensor 5 on the outer side of the guide rail of the distribution plate 2 triggers the vibration motor 4 on that side to start. After the right-side chute 2 is completely closed, the vibration motor 4 continues to vibrate for a period of time before shutting off, further shaking off any remaining clumps. The removed clumps and fragments slide down the inclined wall of the chute 1 into the hopper, where they mix with the main material flow for output, preventing secondary accumulation.
