Description
Technical Field
[0001] This utility model relates to the field of fertilizer filling technology, specifically to a water-soluble fertilizer filling device with quantitative dispensing. Background Technology
[0002] In agricultural production, precise filling of water-soluble fertilizers is a crucial step in ensuring product quality and improving production efficiency. Traditional fertilizer filling methods rely heavily on manual operation or simple weighing devices, resulting in low metering accuracy, high labor intensity, and potential material waste and pollution. To improve filling accuracy and automation, quantitative filling technology has been gradually applied, but the core challenge lies in achieving stable, adjustable, and efficient quantitative delivery. Existing filling equipment is often complex in structure, inconvenient to adjust, or struggles to maintain consistent filling volumes during continuous operation, failing to fully meet the demands of modern production. Utility Model Content
[0003] The purpose of this utility model is to provide a reasonably designed and easy-to-use quantitative dispensing water-soluble fertilizer filling device that addresses the defects and shortcomings of the existing technology, and can effectively solve the defects of the existing technology.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes an outer casing, supporting feet, and a belt conveyor. Supporting feet are fixed to the four corners of the bottom wall of the outer casing. A belt conveyor is installed inside the outer casing, with both sides of the conveyor passing through the side walls of the outer casing and protruding from the outside of the outer casing. A storage bin is installed on one side of the inner casing. It also includes: Two limiting plates are symmetrically arranged inside the outer casing, and the limiting plates are connected to the side wall of the outer casing through a pushing mechanism. The conveying box is connected to one side of the storage box via a connecting pipe. The upper side of the conveying box is inserted through and fixed inside the top wall of the outer box. A discharge pipe is fixed on the bottom wall of the conveying box. A one-way valve is installed in both the discharge pipe and the connecting pipe on the conveying box. A piston plate is disposed inside the conveyor box. A square sleeve is fixed on the upper surface of the piston plate. The upper end of the square sleeve passes through the top wall of the conveyor box, and a square insert rod is connected inside the sleeve through an adjustment mechanism. The drive mechanism is located on the outer top wall of the outer casing. A drive bar is connected to the lower side of the drive mechanism, and the drive bar is fixedly connected to the square plug rod. The above technical solution involves storing fertilizer in a storage bin. The position of the square insert is adjusted by an adjusting mechanism according to the required filling volume. Based on the size of the filling bottle, a pushing mechanism pushes a limiting plate, causing it to limit the filling bottle's position. The bottle is then conveyed by a belt conveyor. When the bottle moves to the lower side of the discharge pipe, the drive mechanism drives the square insert and square sleeve to move up and down via a drive bar. During this up-and-down movement, the piston plate reciprocates. When the piston plate moves upward, it draws fertilizer from the storage bin into the conveying bin; when it moves downward, it feeds fertilizer from the conveying bin into the filling bottle through the discharge pipe. The piston plate moves the same distance up and down, thus achieving quantitative feeding.
[0005] As a further improvement of this utility model, the driving mechanism includes: The push linkage consists of several rods, which are screwed together in pairs via shafts and are located on the side of the limiting plate adjacent to the side wall of the outer housing. The two screwed-together push linkages are respectively screwed onto the limiting plate and the inner wall of the outer housing via hinge seats. The connecting rods consist of four rods, which are symmetrically connected to the side wall of the outer housing in pairs via bearings. The two ends of the connecting rods are fixedly connected to the shafts at the ends of the adjacent push rods. The push rod consists of two rods, which are screwed into the side wall of the outer housing via bearings. The two ends of the push rods are connected to the connecting rods on both sides via worm gear pairs. The linkage rod is screwed into one side wall of the outer housing via a bearing. The linkage rod is connected to the push rods on both sides via a synchronous pulley transmission assembly. One end of the linkage rod is connected to a push motor, which is embedded and fixed in the top wall of the outer housing. The above technical solution starts the drive motor, which drives the linkage rod to rotate. The linkage rod drives the two push rods to rotate through the synchronous wheel transmission assembly. The push rod drives the connecting rod to rotate, and the connecting rod drives the push link to rotate. The push link drives the limit plate to move until the limit plate moves to the appropriate position.
[0006] As a further improvement of this utility model, the adjustment mechanism includes: The internally threaded tube is screwed into the square insert rod via a bearing. The upper end of the internally threaded tube passes through the top of the square insert rod and is screwed into the drive bar via a bearing. A screw rod is screwed into the inside of the internally threaded tube via a thread. The lower end of the screw rod passes through the internally threaded tube and is fixed to the inner bottom wall of the square sleeve. The adjusting rod is screwed into the drive bar via a bearing. The adjusting rod is connected to the top end of the internally threaded tube via a worm gear pair. The outer end of the adjusting rod passes through the side wall of the drive bar and is fixed with a turntable. With the above technical solution, the hand holds the turntable to drive the adjusting rod to rotate. The adjusting rod drives the internal threaded tube to rotate through the worm gear pair. During the rotation, the internal threaded tube moves up and down along the screw, thereby driving the drive bar to move up and down.
[0007] As a further improvement of this utility model, guide rods are fixed on both the front and rear sides of the lower side wall of the drive bar, and the lower end of the guide rod is movably inserted into the top wall of the outer box. The above technical solution can increase the stability of the drive bar when it moves up and down.
[0008] As a further improvement of this utility model, the driving mechanism includes: A fixing plate is fixed to the outer top wall of the outer casing. A drive motor is fixed on one side wall of the fixing plate. The output shaft of the drive motor passes through the fixing plate and is then fixed to the drive plate. The sliding block is slidably disposed in a groove on the side wall of the drive plate. An adjusting screw is threaded onto the sliding block. The adjusting screw is threaded onto the drive plate through a bearing. One end of the adjusting screw passes through one side wall of the drive plate and is exposed on the outside of the drive plate. A toggle lever is fixed to one side wall of the sliding block and is movably inserted into an oblong hole on the side wall of the drive bar. Using the above technical solution, according to the required material feeding amount, the adjusting screw is rotated, the adjusting screw drives the sliding block to move up and down, the sliding block drives the actuating rod to move up and down until it reaches the appropriate position, then the drive motor is started, the drive motor drives the drive plate to rotate, the drive plate drives the actuating rod to rotate through the sliding block, and the actuating rod drives the drive bar to move up and down.
[0009] As a further improvement of this utility model, the outer end of the adjusting screw is fixed with a rotating plate, and the rotating plate is suspended on the outside of the drive plate. The above technical solution facilitates the rotation of the adjusting screw.
