Description

Fertilizer spreading mechanism of a fertilizer spreader Technical Field

[0001] This utility model relates to the field of fertilizer spreading technology, and more specifically, to a fertilizer spreading mechanism of a fertilizer spreader. Background Technology

[0002] In existing technologies, fertilizer spreading mechanisms of fertilizer spreaders often face several key problems, especially the difficulty in continuous and directional spreading of fertilizer and the problem that the discharge pipe is prone to blockage and is difficult to clear. This seriously affects the working efficiency and service life of fertilizer spreaders.

[0003] In traditional fertilizer spreaders, the quantitative distribution of fertilizer relies on simple mechanical or airflow control systems. However, these systems often fail to precisely control the directional application of fertilizer. Uneven fertilizer flow during operation can easily lead to discontinuous and uneven application, or even fertilizer blockage or retention. For example, fertilizer can easily get stuck in the spreading mechanism, especially with moist or sticky fertilizers. Because fertilizer spreaders lack effective continuous control mechanisms, fertilizer accumulation and retention frequently occur, significantly reducing the speed and uniformity of application.

[0004] As a crucial part of fertilizer delivery in a fertilizer spreader, blockages in the discharge pipe directly affect the smooth operation of the entire fertilizer spreading process. During the fertilizer delivery process, blockages often occur due to the viscosity or large particle size of the fertilizer, especially in humid or low-temperature environments, where the fluidity of the fertilizer decreases, making it easy to accumulate and form blockages in the discharge pipe. Once a blockage occurs, traditional fertilizer spreaders usually rely on manual cleaning or rough mechanical methods to clear it, which not only increases labor costs but may also damage other parts of the equipment and even lead to accelerated wear and tear on components after long-term use. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a fertilizer spreading mechanism for a fertilizer spreader to solve the technical problems mentioned in the background art, such as the difficulty in continuous and directional spreading of fertilizer and the easy blockage and difficulty in clearing of the discharge pipe.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer spreading mechanism for a fertilizer spreader, comprising a control box, a quantitative flipping mechanism, a discharge and unblocking mechanism, and an unblocking auxiliary mechanism. The quantitative flipping mechanism includes a drive motor, a rotating shaft, a quantitative shaft, a quantitative groove, and a scraper. The rotating shaft is configured to cooperate with the drive motor and is rotatably installed inside the control box. A directional shaft is installed on the rotating shaft, and multiple sets of directional grooves are annularly arranged on the directional shaft. The scraper is fixedly installed inside the control box. The rotating directional grooves and the scraper connect the top and bottom of the control box. The discharge and unblocking mechanism includes a unblocking pipe, a rotating sleeve, a mating groove, a rotary push block, a rotary push spring, a limiting plate, and an unblocking plate. The rotating sleeve is rotatably mounted on the outer wall of the unblocking pipe. The mating groove is located on the inner wall of the rotating sleeve. The rotary push block is rotatably mounted inside the mating groove. The two ends of the rotary push spring are installed between the inner wall of the mating groove and the side of the rotary push block. The limiting plate is installed on the rotary push block and contacts the inner wall of the unblocking pipe. The unblocking plate is installed on the side of the limiting plate.

[0009] The present invention is further configured such that the unblocking auxiliary mechanism includes an outer rotating sleeve, a linkage plate, a fixed plate, a rotating column, a tensioning spring, and a centripetal column. The outer rotating sleeve is rotatably mounted on the outer wall of the unblocking pipe. The two ends of the linkage plate are connected to the rotating sleeve and the outer rotating sleeve, and the rotating sleeve is arranged symmetrically up and down. The fixed plate is fixedly mounted on the outer wall of the clamping pipe. Multiple sets of centripetal columns are slidably mounted on the fixed plate. The tensioning spring is installed between adjacent centripetal columns. The rotating column is installed on one end face of the rotating sleeve. The rotating column rotates sequentially between adjacent centripetal columns, so that the outer rotating sleeve drives the two sets of rotating sleeves to rotate stably.

[0010] The present invention is further configured such that an adding hopper is installed on the top end of the control box, and fertilizer is added to the control box through the adding hopper. The adding hopper makes it easy to add fertilizer into the control box, simplifies the operation process, and reduces the risk of fertilizer leakage and waste.

[0011] The present invention is further configured such that a bracket is installed at the bottom of the control box, and the device is fixed in the required position by the bracket, and the drive motor is installed on the side of the bracket. The bracket ensures the stability of the entire device, so that the fertilizer spreader can be fixed in the required position.

[0012] The present invention is further configured such that a main wheel is installed at the output end of the drive motor, and a driven wheel is installed at one end of the rotating shaft. A transmission belt is installed between the main wheel and the driven wheel. Through the cooperation of the main wheel and the driven wheel, the transmission belt can effectively transmit power from the motor to the rotating shaft, ensuring the stable operation of the fertilizer spreading mechanism. At the same time, by adjusting the wheel speed, the spreading rate and uniformity of the fertilizer spreader can be controlled.

[0013] The present invention is further configured such that a connecting pipe is provided through the bottom end of the control box, and one end of the connecting pipe is connected to one end of the unblocking pipe.

[0015] The present invention is further configured such that a centripetal rail is installed on one end face of the fixed plate, and the centripetal column is slidably arranged on the centripetal rail. The centripetal rail and the centripetal column cooperate to ensure the sliding stability of the centripetal column, avoid component wear or failure caused by vibration or friction, and improve the long-term reliability of the equipment.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a fertilizer spreading mechanism for a fertilizer spreader, which has the following beneficial effects:

[0018] This invention features a quantitative flipping mechanism. Through the cooperation of a quantitative trough and a scraper, the quantitative flipping mechanism can precisely control the amount of fertilizer flipped each time, ensuring uniform spreading of fertilizer and improving the accuracy of fertilizer application. The design of the rotating shaft and drive motor ensures the stability of the entire flipping process, helping to reduce equipment failure and extend service life. The linkage between the directional trough and the scraper can efficiently flip and transport the fertilizer in the control box, ensuring that the fertilizer will not clog and guaranteeing smooth fertilizer application.

[0019] This utility model is equipped with a discharge and unblocking mechanism. The design of components such as the unblocking pipe, rotating sleeve, rotating push block, and rotating push spring effectively avoids the phenomenon of fertilizer blockage during discharge, ensuring that the fertilizer can flow out quickly. The combination of rotating push spring and rotating push block gives the unblocking mechanism a flexible cleaning function, ensuring continuous and uninterrupted operation. Through the design of the groove and rotating sleeve, the unblocking mechanism can discharge fertilizer evenly and orderly from the unblocking pipe, ensuring a more uniform spreading effect and avoiding waste.

[0020] This utility model incorporates a dredging auxiliary mechanism. The design of the outer rotating sleeve, linkage plate, and centripetal column effectively enhances the stability of the dredging auxiliary mechanism, ensuring that the entire system can still operate smoothly under high load. Through the sliding cooperation of the centripetal column and centripetal rail, direct friction between components is reduced, effectively extending the service life. The design of the linkage plate and rotating sleeve enables the outer rotating sleeve to drive the two rotating sleeves to rotate stably, thereby enhancing the working efficiency of the entire dredging system and ensuring the smooth discharge of fertilizer.

After quantitative turning, the fertilizer is discharged through unblocking pipe 7. Rotating sleeve 8 and rotary push block 10, under the action of rotary push spring 11, drive unblocking plate 13 and limiting plate 12 to work together to ensure that the fertilizer can be discharged smoothly and to avoid blockage.
