A powder feeding device for an integrated water and fertilizer machine

Abstract

This utility model relates to the technical field of powder feeding devices, providing a powder feeding device for an integrated water and fertilizer machine. It includes a base plate with legs fixed to the bottom edge of the base plate. A storage cylinder is installed at the top of the base plate, and a stirring structure is installed inside the storage cylinder. A feeding structure is also provided inside the base plate. This utility model utilizes the feeding structure, where a second motor drives two sets of threaded rods to rotate synchronously via a transmission gear and a transmission belt. This causes the threaded blocks to drive a moving plate in a smooth linear motion. During the movement of the moving plate, the upright plate drives the rotating block and the cover plate to move synchronously. During feeding, the cover plate automatically flips open with the displacement of the moving plate and automatically closes after feeding, returning to its original position. Simultaneously, the moving plate can block the discharge pipe, thus preventing powder leakage during the feeding process.

Description

Technical Field

[0001] This utility model relates to the technical field of powder feeding devices, and in particular to a powder feeding device for an integrated water and fertilizer machine. Background Technology

[0002] A powder feeding device is an automated or semi-automated mechanical device specifically designed to take solid powder or granular materials from a storage container and deliver them stably and accurately to the target equipment according to a preset speed, dosage, or path. The powder feeding device of the fertigation machine is a core functional component designed specifically for the fertigation system. Its core function is to accurately take solid fertilizer powder from the storage container and deliver it stably and efficiently to the dissolving and mixing unit of the fertigation machine according to a preset fertilizer ratio, conveying speed, or dosage, so that it can be mixed with water in a set ratio to form a uniform fertigation solution.

[0003] Traditional water and fertilizer integrated machine powder feeding devices rely on manual pushing during use, depending on the operator's experience to judge the feeding amount. This makes it difficult to achieve quantitative control and is prone to displacement of the feeding parts, resulting in a large deviation between the feeding distance and the actual requirement, which in turn affects the stability of the powder feeding amount. Utility Model Content

[0004] The purpose of this utility model is to provide a powder feeding device for an integrated water and fertilizer machine, so as to solve the defect of the existing powder feeding device for integrated water and fertilizer machines being inconvenient for feeding.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a powder feeding device for an integrated water and fertilizer machine, including a base plate;

[0006] Support legs are fixed at the bottom edge of the base plate, a storage cylinder is installed at the top of the base plate, a feed hopper is fixed on one side of the top of the storage cylinder, a discharge pipe is fixed at the bottom of the storage cylinder, and a stirring structure is installed inside the storage cylinder.

[0007] The base plate has a feeding structure inside, which includes a chute inside the base plate. There are built-in grooves on both sides of the chute inside the base plate. A threaded rod is installed inside the built-in groove. A threaded block is installed on the outside of the threaded rod. A movable plate is fixed between the threaded blocks inside the chute. A discharge port is provided on one side of the movable plate. A feeding cylinder is fixed at the bottom end of the movable plate below the discharge port. A vertical plate is fixed on one side of the feeding cylinder.

[0008] Preferably, a first motor is fixed to the top of the storage cylinder, a rotating shaft is fixed to the output end of the first motor inside the storage cylinder, a stirring rod is fixed to the outside of the rotating shaft, a scraper is fixed to one end of the stirring rod, and a stirring blade is fixed to the bottom end of the scraper.

[0009] Preferably, the stirring rods are evenly spaced on the outside of the rotating shaft, one side of the scraper abuts against the inside of the storage cylinder, and one side of the stirring blade abuts against the inside of the discharge pipe.

[0010] With the above structure, the design of the scraper side closely contacting the inner side of the storage cylinder during use allows for real-time scraping of powder adhering to the inner wall of the storage cylinder when the rotating shaft drives the scraper to rotate synchronously with the stirring rod. When the stirring blade rotates with the rotating shaft, its contact with the inner side of the discharge pipe can real-time agitate and push the powder in the discharge pipe: it can break up any small clumps that may form in the discharge pipe, preventing clumps from clogging the pipe diameter; at the same time, by continuously agitating and pushing the powder downwards into the feeding structure, it avoids the powder from stagnating and accumulating in the discharge pipe, ensuring that the feeding channel from the storage cylinder to the feeding cylinder is unobstructed throughout.

[0011] Preferably, rotating blocks are installed on both sides of the bottom of the upright plate, a cover plate is fixed to one end of the rotating block, a support plate is fixed to the bottom end of the bottom plate below the cover plate, a transmission gear is fixed to one end of the threaded rod on one side of the bottom plate, a transmission toothed belt is installed on the outside of the transmission gear, and a second motor is fixed to one end of the transmission gear on one side of the bottom plate.

[0012] Preferably, the built-in grooves are symmetrically distributed on both sides of the sliding groove inside the base plate, the threaded rod and the threaded block are threadedly connected, the threaded blocks are symmetrically distributed on both sides of the moving plate, the diameter of the discharge port is the same as the inner diameter of the discharge pipe, and the inside of the feeding cylinder and the discharge pipe are connected through the discharge port.

[0013] With the above structure, the diameter of the discharge port is the same as the inner diameter of the discharge pipe during use, so that no gap will occur due to mismatch in interface size during the process of powder entering the feeding cylinder from the discharge pipe, thus avoiding raw material waste caused by powder leakage.

[0014] Preferably, the rotating blocks are symmetrically distributed on both sides of the upright plate, the rotating blocks and the upright plate are hinged together by a hinge shaft, the bottom end of the cover plate abuts against the top end of the support plate, and the transmission gear is meshed with the transmission belt.

[0015] With the above structure, when the upright plate moves synchronously with the moving plate during use, the rotating blocks on both sides can synchronously drive the cover plate to rotate around the hinge axis, ensuring that the cover plate flipping process is smooth and stable, and allowing the cover plate to flexibly adjust the flipping angle according to the displacement direction of the upright plate.

[0016] The advantages of the powder feeding device for the integrated water and fertilizer machine provided by this utility model are as follows:

[0017] Equipped with a stirring structure, the first motor drives the rotating shaft, which in turn rotates the evenly spaced stirring rods. This allows for omnidirectional radial stirring of the powder in the storage cylinder, directly breaking up any clumps of powder raw materials and preventing conveying obstructions caused by powder agglomeration. Simultaneously, the stirring blades at the bottom of the rotating shaft closely contact the inside of the discharge pipe, continuously agitating the powder within the pipe and preventing powder accumulation and blockage from the source, ensuring unobstructed transport of the powder from storage to discharge.

[0018] With a feeding structure, the second motor drives two sets of threaded rods to rotate synchronously via the meshing of transmission gears and a transmission belt. This causes the threaded blocks to drive the moving plate in a smooth linear motion. During the movement of the moving plate, the vertical plate drives the rotating block and the cover plate to move synchronously. When feeding, the cover plate automatically flips open as the moving plate moves, and automatically closes after feeding is complete, returning to its original position. Simultaneously, the moving plate can block the discharge pipe, thus preventing powder leakage during the feeding process. Attached Figure Description

Detailed Implementation

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.

[0026] Please see Figures 1-5 The present invention provides a powder feeding device for an integrated water and fertilizer machine, including a base plate 1.

[0027] Reference Figure 2 , Figure 3 and Figure 5 As shown, support legs 2 are fixed at the bottom edge of the base plate 1. A storage cylinder 3 is installed at the top of the base plate 1. A feed hopper 4 is fixed to one side of the top of the storage cylinder 3. A discharge pipe 5 is fixed to the bottom of the storage cylinder 3. A stirring structure 6 is installed inside the storage cylinder 3. A first motor 601 is fixed to the top of the storage cylinder 3. A rotating shaft 602 is fixed to the output end of the first motor 601 inside the storage cylinder 3. A stirring rod 603 is fixed to the outside of the rotating shaft 602. A scraper 604 is fixed to one end of the stirring rod 603. A stirring blade 605 is fixed to the bottom of the scraper 604. The stirring rods 603 are evenly distributed outside the rotating shaft 602. One side of the scraper 604 abuts against the inside of the storage cylinder 3. One side of the stirring blade 605 abuts against the inside of the discharge pipe 5.

[0028] The pneumatic first motor 601 drives the rotating shaft 602 to rotate synchronously. The stirring rods 603, which are evenly distributed on the outside of the rotating shaft 602, rotate synchronously to radially stir the powder in the storage cylinder 3 and break up the clumps of powder. At the same time, the stirring blades 605 at the bottom of the rotating shaft 602 further agitate the powder in the discharge pipe 5 to prevent the powder from clogging the discharge pipe 5 and to ensure that the powder is mixed evenly and in a loose state. The scraper 604 is in close contact with the inside of the storage cylinder 3. When it rotates with the rotating shaft 602, it can scrape off the powder adhering to the inner wall of the storage cylinder 3 in real time to avoid waste of raw materials and prevent the powder on the wall from hardening and affecting the subsequent stirring effect.

[0029] Reference Figures 1-4As shown, a feeding structure 7 is provided inside the base plate 1. The feeding structure 7 includes a chute 701 inside the base plate 1. Built-in grooves 702 are provided on both sides of the chute 701 inside the base plate 1. A threaded rod 703 is installed inside the built-in groove 702. A threaded block 704 is installed on the outside of the threaded rod 703. A movable plate 705 is fixed between the threaded blocks 704 inside the chute 701. A discharge port 706 is provided on one side of the movable plate 705. A feeding cylinder 707 is fixed to the bottom end of the movable plate 705 below the discharge port 706. A vertical plate 708 is fixed to one side of the feeding cylinder 707. Rotating blocks 709 are installed on both sides of the bottom of the vertical plate 708. A cover plate 710 is fixed to one end of the rotating block 709. A support plate 711 is fixed to the bottom end of the base plate 1 below the cover plate 710. The threaded rod 703 on one side of the base plate 1... One end of each is fixed with a transmission gear 712, and a transmission toothed belt 713 is installed on the outside of the transmission gear 712. A second motor 714 is fixed to one end of the transmission gear 712 on one side of the base plate 1. The built-in groove 702 is symmetrically distributed on both sides of the sliding groove 701 inside the base plate 1. The threaded rod 703 is threadedly connected to the threaded block 704. The threaded block 704 is symmetrically distributed on both sides of the moving plate 705. The diameter of the discharge port 706 is the same as the inner diameter of the discharge pipe 5. The feeding cylinder 707 is connected to the inside of the discharge pipe 5 through the discharge port 706. The rotating block 709 is symmetrically distributed on both sides of the upright plate 708. The rotating block 709 and the upright plate 708 are hinged together by the hinge shaft. The bottom end of the cover plate 710 abuts against the top end of the support plate 711. The transmission gear 712 and the transmission toothed belt 713 are meshed together.

[0030] The powder inside the discharge pipe 5 enters the feeding cylinder 707 through the discharge port 706, which in turn drives the transmission gear 712 to rotate by starting the second motor 714. Since the transmission gear 712 is meshed with the transmission belt 713, the power is transmitted to the transmission gear 712 on the other side through the transmission belt 713, which in turn drives the two sets of threaded rods 703 to rotate synchronously. When the threaded rods 703 rotate, the threaded block 704 moves linearly along the axial direction of the threaded rods 703. Since the threaded block 704 is fixedly connected to the moving plate 705, the moving plate 704 moves linearly along the axial direction of the threaded rods 703. The moving plate 705 moves synchronously with the threaded block 704, which in turn gradually drives the feeding cylinder 707 to move, causing the vertical plate 708 to move synchronously. The rotating block 709 rotates along with the hinge shaft, pushing the cover plate 710 to flip open around the hinge shaft. At this time, the moving plate 705 blocks the discharge pipe 5, causing the cover plate 710 to open and discharge the powder inside the feeding cylinder 707. After the feeding is completed, the second motor 714 rotates in reverse, driving the moving plate 705 to reset, and the cover plate 710 closes again, waiting for the next feeding cycle.
