Description

Technical Field

[0001] This application relates to the field of liquid fertilizer production equipment technology, and in particular to a liquid fertilizer filling and conveying device. Background Technology

[0002] Liquid fertilizers include fertilizers in solution form and fertilizers in suspension containing solid particles. Existing equipment requires mixing and filling when producing liquid fertilizers, therefore there is a market demand for highly automated filling equipment for the filling operation.

[0003] Existing conveying devices typically use conveyor belts for transport, as shown in the patent document with publication number CN216762236U. Although these devices can also transport filling barrels, the large mass of the barrels makes them prone to slippage on the conveyor belt surface, especially during start-up and stop. Some devices use a method where the conveyor belt does not stop but clamps and limits the filling barrels for filling. While this can also achieve filling and transport, the bottom of the limited filling barrel will rub against the surface of the conveyor belt, which is likely to scratch the appearance of the filling barrels and affect sales.

[0004] Therefore, there is an urgent need for a conveying device that can both ensure the stability of the filling barrel transportation process and avoid damage to the filling barrels. Utility Model Content

[0005] The purpose of this application is to provide a liquid fertilizer filling and conveying device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution of this application is as follows:

[0007] A liquid fertilizer filling and conveying device includes a chain conveyor assembly, which includes several hinged conveyor plates. One side of each conveyor plate, which is used to support a filling barrel, is elastically provided with a limiting protrusion. Protective rod assemblies are provided on both sides of the chain conveyor assembly.

[0008] Preferably, the conveyor plate is provided with a first sliding hole and a second sliding hole, the first sliding hole and the second sliding hole communicating with each other and passing through the conveyor plate; the diameter of the first sliding hole is smaller than that of the second sliding hole;

[0009] The sliding section of the limiting protrusion is located in the first sliding hole, and the limiting section of the limiting protrusion is located in the second sliding hole; a spring is provided in the second sliding hole to provide elasticity for the limiting protrusion.

[0010] Preferably, a plug is also screwed into the second sliding hole, and the spring is located between the plug and the limiting protrusion.

[0011] Preferably, the section of the sliding segment furthest from the limiting segment is provided with an arc-shaped guide surface.

[0012] Preferably, it also includes a frame, on which both the chain conveyor group and the guard rod group are mounted.

[0013] Preferably, the frame is provided with two sets of support rods, and the conveying direction of the chain conveyor group is consistent with the length direction of the support rods; between the two support rods, there are a number of support rollers arranged at intervals along the length direction of the support rods, and the two ends of the support rollers are respectively rotatably mounted on the two support rods.

[0014] Preferably, the outer peripheral wall of the bearing rod is provided with a rubber sleeve.

[0015] Preferably, the protective rod assembly includes a protective rod and an adjustment component, wherein the adjustment component includes a connecting frame, a limiting sleeve, an adjustment seat, and an adjustment knob;

[0016] The connecting frame is mounted on the machine frame, and the limiting sleeve is located at the end of the connecting frame away from the machine frame. The limiting sleeve has a sliding hole and a threaded hole. The sliding hole passes through the limiting sleeve, and the threaded hole communicates with the sliding hole. The adjusting knob is threadedly engaged with the threaded hole. One end of the adjusting seat is located in the sliding hole, and the protective rod is engaged at the end of the adjusting seat away from the limiting sleeve.

Detailed Implementation

[0027] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0028] like Figure 1-7 As shown, a liquid fertilizer filling and conveying device includes a chain conveyor group 1, which includes several hinged conveyor plates 10. One side of the conveyor plate 10 for supporting the filling barrel 3 is elastically provided with a limiting protrusion 11. The chain conveyor group 1 is provided with protective rods 40 on both sides.

[0029] This liquid fertilizer filling and conveying device uses a chain conveyor group 1 instead of a traditional conveyor belt. The chain conveyor group 1 consists of several articulated conveyor plates 10 connected end to end to form a closed loop.

[0030] Each conveyor plate 10 has a limiting protrusion 11 elastically set on its bearing surface. When the filling barrel 3 is placed on the conveyor plate 10, the limiting protrusion 11 located at the edge of the filling barrel 3 fits exactly against the outer peripheral wall of the barrel body. The elastic force achieves self-adaptive limiting and prevents the barrel body from sliding.

[0031] The chain conveyor group 1 is equipped with 40 sets of protective rods on both sides. The 40 sets of protective rods maintain a small gap with the outer wall of the filling barrel 3, forming a double anti-deviation structure to avoid the risk of the filling barrel 3 tipping over. At the same time, it can also prevent external equipment from interfering with the filling barrel 3 during the movement process.

[0032] This design uses multiple flexible limiters arranged in the chain conveyor group 1 to limit the filling barrel 3 placed on the chain conveyor group 1, which solves the problem of slippage of traditional conveyor belts and avoids friction damage to the barrel body caused by the clamping device. It is especially suitable for the stable conveying of large-mass filling barrels 3.

[0033] In some further embodiments, the conveyor plate 10 is provided with a first sliding hole 14 and a second sliding hole 15, the first sliding hole 14 and the second sliding hole 15 are connected and pass through the conveyor plate 10; the diameter of the first sliding hole 14 is smaller than that of the second sliding hole 15; the sliding section 112 of the limiting protrusion 11 is located in the first sliding hole 14, and the limiting section 110 of the limiting protrusion 11 is located in the second sliding hole 15; a spring 13 is provided in the second sliding hole 15 to provide elasticity for the limiting protrusion 11.

[0034] The conveyor plate 10 has a double-layer sliding hole 52 structure. The first sliding hole 14 serves as a guide channel, and its diameter is smaller than that of the second sliding hole 15. The limiting protrusion 11 consists of a stepped shaft structure composed of a sliding section 112 and a limiting section 110. The sliding section 112 slides linearly in the first sliding hole 14, and the limiting section 110 compresses the spring 13 in the second sliding hole 15. When the filling barrel 3 is placed, the barrel body presses down on the limiting protrusion 11, causing a "recess" in the plane formed by the entire limiting protrusion 11. The filling barrel 3 can then be located in the "recess," meaning that the limiting protrusion 11 that is not pressed down on the outer periphery will limit the outer wall of the filling barrel 3, preventing the filling barrel 3 from sliding during the conveying process.

[0035] In some further embodiments, a plug 12 is also screwed into the second sliding hole 15, and a spring 13 is located between the plug 12 and the limiting protrusion 11.

[0036] A removable plug 12 is provided at the end of the second sliding hole 15. The plug 12 is screwed into the inner wall of the sliding hole 52 via an external thread. The spring 13 is confined between the plug 12 and the limiting protrusion 11, forming a closed elastic space. By rotating the plug 12, its initial distance from the limiting section 110 can be adjusted, thereby controlling the pre-compression of the spring 13 and achieving stepless adjustment of the limiting force.

[0037] Plug 12 can be a set screw.

[0038] In some further embodiments, the section of the sliding segment 112 away from the limiting segment 110 is provided with an arcuate guide surface 113.

[0039] The sliding section 112 has a circular arc guide surface 113 at its front end. When the filling barrel 3 is placed, the bottom edge of the barrel first contacts the circular arc guide surface 113. The curved surface guides the limiting protrusion 11 to gradually compress the spring 13, avoiding jamming caused by the right-angle edge. The design of the circular arc guide surface 113 decomposes the vertical impact force into an axial component, significantly reducing the impact noise when the barrel is placed, while also reducing the hard collision between the limiting protrusion 11 and the bottom of the barrel, extending the service life of both.

[0040] The arc-shaped guide surface 113 can also greatly buffer the degree of shaking of the filling barrel 3 during the process of placing it into the chain conveyor group 1.

[0041] In some further embodiments, a frame 2 is also included, on which the chain conveyor group 1 and the guard rod group 40 are both mounted.

[0042] The frame 2, serving as the overall support structure, is welded from high-strength steel, and an installation platform is set on its upper surface. The chain conveyor group 1 is tensioned and fixed to the installation platform by the driving sprocket and the driven sprocket, and the guard rods 40 are bolted to both sides of the frame 2.

[0043] This modular design allows the conveyor assembly and the 40 protective bars to be disassembled and assembled independently, facilitating transportation and on-site assembly.

[0044] In other embodiments, the bottom of the frame 2 is provided with adjustable feet. By rotating the feet, the level of the equipment can be finely adjusted to ensure the stable operation of the chain conveyor group 1 in complex ground environments and effectively avoid the problem of conveying stability caused by uneven ground.

[0045] In some further embodiments, the frame 2 is provided with two sets of support rods, and the conveying direction of the chain conveyor group 1 is consistent with the length direction of the support rods; between the two support rods, there are a number of support rollers 20 arranged at intervals along the length direction of the support rods, and the two ends of the support rollers 20 are respectively rotatably mounted on the two support rods.

[0046] Two sets of support rods are symmetrically arranged on the frame 2. The support rods can be angle steel.

[0047] The support roller 20 is rotatably mounted between the two support rods via bearings, and its axis is perpendicular to the direction of movement of the chain conveyor group 1. When the filling barrel 3 is conveyed, the conveyor plate 10 pressed down by the filling barrel 3 simultaneously contacts multiple support rollers 20, converting sliding friction into rolling friction and reducing wear between the equipment.

[0048] The support rollers 20 are evenly distributed along the length of the support rod to form a continuous support surface, which effectively disperses the weight of the filling barrel 3 and avoids deformation of the conveyor plate 10 caused by local stress concentration.

[0049] In some further embodiments, the outer peripheral wall of the support rod is provided with a rubber sleeve.

[0050] The support rod is wrapped with a rubber sleeve, which is tightly bonded to the support rod through a vulcanization process. The surface of the rubber sleeve can also be textured with anti-slip patterns. When the support roller 20 rotates, the elastic deformation of the rubber sleeve can absorb some of the vibration energy, providing a shock-absorbing effect. At the same time, the anti-slip patterns increase the coefficient of friction between the support roller 20 and the bottom of the barrel, preventing sliding friction between the barrel and the support roller during acceleration / deceleration.

[0051] In some further embodiments, the protective rod 40 group includes a protective rod and an adjustment assembly. The adjustment assembly includes a connecting frame 50, a limiting sleeve 51, an adjustment seat 53, and an adjustment knob 54. The connecting frame 50 is disposed on the frame 2, and the limiting sleeve 51 is disposed at the end of the connecting frame 50 away from the frame 2. The limiting sleeve 51 has a sliding hole 52 and a threaded hole. The sliding hole 52 penetrates the limiting sleeve 51, and the threaded hole communicates with the sliding hole 52. The adjustment knob 54 is threadedly engaged with the threaded hole. One end of the adjustment seat 53 is located in the sliding hole 52, and the protective rod is engaged at the end of the adjustment seat 53 away from the limiting sleeve 51.

[0052] The connecting frame 50 is bolted to the column of the frame 2, and the limiting sleeve 51 is welded to the top of the connecting frame 50. The adjusting seat 53 has a T-shaped structure, with its vertical section slidingly disposed in the sliding hole 52 of the limiting sleeve 51, and its horizontal section used to engage the protective rod. When the adjusting knob 54 is rotated, its end presses against the vertical section of the adjusting seat 53, thereby locking the protective rod 40 through friction.

[0053] The vertical and horizontal sections of the adjustment seat 53 represent the lower and upper parts of the "T"-shaped structure, respectively, and do not represent the specific spatial and temporal orientation of the component during installation.

[0054] When the position of the protective rod needs to be adjusted, simply loosen the adjustment knob 54 to slide the adjustment seat 53, so that the protective rod is closer to or further away from the filling barrel 3. This design allows the protective rod to be quickly adapted to filling barrels 3 of different thicknesses, effectively preventing the barrel from tipping over during transportation and avoiding external interference.

[0055] The protective rod can be engaged by setting an open-type elastic rubber clamp on the adjusting seat 53.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
