Description

A single-compartment multi-material-cell feeding bin Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, and in particular to a single-compartment multi-material-grid feeding hopper. Background Technology

[0002] A single-compartment, multi-compartment feeding silo is a commonly used piece of equipment in industrial production and warehousing logistics. It consists of a silo body, typically a large, monolithic container. The interior is divided into multiple independent material compartments by partitions or other structures. The size and number of each compartment can be flexibly designed according to the type of material and usage requirements. The compartments are independent of each other, preventing mixing or cross-contamination between different materials. Each compartment has a corresponding feeding port and discharge port. A silo door at the top of the feeding port allows for opening and closing.

[0003] In the existing technology, each material compartment's feeding port is matched with an independent door for opening and closing, and each door is controlled by a separate drive device, with each door being separate and not connected; this results in a complex structure, large space occupation, and high cost and energy consumption for a single-compartment multi-material-cell feeding bin. Summary of the Invention

[0004] The purpose of this invention is to provide a single-compartment, multi-material-cell feeding hopper that solves the technical problems of complex structure, large space occupation, and high cost and energy consumption in existing single-compartment, multi-material-cell feeding hoppers. This invention has a simple structure and lower cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A single-compartment multi-material-cell feeding bin includes a feeding bin body; the feeding bin body is divided into at least two groups of parallel material-cell units, each group of material-cell units including two material-cell units distributed front to back;

[0007] Each material compartment unit is connected to a mother-daughter compartment door assembly at its upper end;

[0008] The mother and daughter compartment door assembly includes a mother compartment door, a daughter compartment door located below the mother compartment door, and a compartment door drive cylinder; the compartment door drive cylinder includes a cylinder body and a cylinder piston rod; the cylinder body is fixed to the upper end of the mother compartment door, and the cylinder piston rod extends laterally and is connected to the upper end of the daughter compartment door; the lower left and right sides of the mother compartment door are slidably connected to the upper end of the feeding compartment body.

[0009] Each mother and daughter compartment door assembly is equipped with an electromagnetic bolt lock on both the front and rear sides, and the mother and daughter compartment doors have pin holes that cooperate with the electromagnetic bolt lock.

[0010] The front side of the sub-door and the rear side of the mother door are respectively provided with a sub-door stop block and a mother door stop block.

[0011] Furthermore, the lower end of the feeding hopper is connected to an integrated slide valve for opening and closing the material outlet.

[0012] The integrated slide gate valve includes a valve body frame; the valve body frame is provided with a plurality of valve plates for opening and closing the material compartment outlets, each valve plate being controlled by a separate linear drive device; the number of valve plates is the same as the number of material compartments.

[0013] Furthermore, sealing strips are installed between the valve plates to prevent material leakage.

[0014] Furthermore, it includes three sets of material compartment units.

[0015] Furthermore, displacement sensors are respectively provided on the front side of the sub-door and the rear side of the mother door.

[0016] Compared with the prior art, this utility model provides a single-compartment multi-material-cell feeding bin, which has the following features:

[0017] Beneficial effects:

[0018] 1. In this invention, a mother-daughter door assembly is used at the top of each material compartment unit. The mother and daughter doors are connected by a single cylinder, enabling a single cylinder to drive the opening and closing of both doors. Thus, compared to the prior art design where each door has its own drive component, this invention reduces the number of drive components; the reduction in drive components further reduces the overall size of the equipment.

[0019] 2. In this embodiment, an integrated slide gate valve with an openable / closeable material compartment outlet is provided at the lower end of the feeding hopper. This slide gate valve adopts an integrated structure design, that is, each valve plate is connected within the same valve body frame, resulting in a more compact structure and improved space utilization and ease of maintenance. In contrast, in the existing traditional slide gate valve structure, each material compartment outlet is individually matched with a valve plate at the lower end of the feeding hopper, each valve plate is controlled by a separate drive device, and each valve plate is matched with a separate valve plate frame. The valve plate frames are independent of each other and not connected, which makes the installation of the slide gate valve in the traditional structure more time-consuming and labor-intensive.

[0020] This utility model proposes a storage door control scheme with high space utilization and compact structure. By using a single cylinder to drive double storage doors and an integrated slide gate valve design, it significantly reduces equipment costs and maintenance difficulty. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] As shown in Figures 1 to 4, this utility model provides a single-compartment multi-material-cell feeding bin, including a feeding bin body 100; the feeding bin body 100 is divided into three groups of parallel material-cell units, each group of material-cell units including two material-cell units distributed front and back; as shown in Figures 1-2, the feeding bin body 100 is divided into a total of six independent material-cell units, the six material-cell units presenting a 2 × The six material compartments are arranged in a six-grid pattern. Each compartment is vertically connected, with the top end serving as the feeding port and the bottom end as the discharge port. As shown in Figures 1 and 2, the six material compartments can be divided into three groups of compartment units from left to right, with each group containing two compartments arranged in a front-to-back pattern.

[0031] The feeding hopper body 100 is composed of two parts, upper and lower. Figure 3 shows a schematic diagram of the connection structure between the upper part of the feeding hopper body 100 and the mother-daughter hopper door assembly. As shown in Figure 3, each set of material compartments includes two material compartments arranged side by side; and each material compartment unit has a mother-daughter hopper door assembly connected to its upper end for opening and closing the two feeding ports of the two material compartments within a single set of material compartments. In this embodiment, a total of three sets of mother-daughter hopper door assemblies are included, arranged side by side as shown in Figure 1.

[0032] In this embodiment, each set of mother and daughter door assemblies includes a mother door 301, a daughter door 302 located below the mother door 301, and a door driving cylinder. The door driving cylinder includes a cylinder body 303 and a cylinder piston rod 304. The cylinder body 303 is fixed to the upper end of the mother door 301. The cylinder piston rod 304 extends laterally back and forth, as shown in Figure 2. The front end of the cylinder piston rod 304 is connected to the upper end of the daughter door 302 near the edge via a floating joint. The lower left and right sides of the mother door 301 are slidably connected to the upper end of the feeding bin body 100.

[0033] In this embodiment, a door drive cylinder with a magnetic switch and a magnetic ring can be used; the magnetic switch is connected to the cylinder body 303, and the magnetic ring is connected to the cylinder piston rod 304.

[0034] Specifically, in this embodiment, the upper end of the feeding hopper body 100 is provided with six parallel guide rods 102. The left and right sides of the lower end of each mother hopper door 301 are slidably connected to two guide rods 102 at the upper end of the feeding hopper body 100. The guide rods 102 extend back and forth, and are distributed parallel to each other left and right. As shown in Figure 2, the lower end of the mother hopper door 301 is provided with a through-hole, through which the guide rods 102 pass. Because the through-hole has a restraining effect on the guide rods 102, the mother hopper door 301 can move precisely back and forth along the guide rods 102 without deviation during the back-and-forth movement of the mother hopper door 301.

[0035] The door drive cylinder is located at the upper center of the mother and daughter doors, and is connected to two doors in the same mother and daughter door assembly (i.e., a mother door 301 and a daughter door 302).

[0036] In the mother and daughter compartment door assembly, the daughter compartment door 302 is connected below the mother compartment door 301, and both the daughter compartment door 302 and the mother compartment door 301 are connected to the compartment door drive cylinder. When the mother compartment door 301 is locked and stationary, the piston rod 304 of the cylinder moves, which will drive the daughter compartment door 302 to move relative to the mother compartment door 301 in the front-back direction, thereby changing the relative position of the mother compartment door 301 and the daughter compartment door 302 in the front-back direction. Similarly, when the daughter compartment door 302 is locked and stationary, the mother compartment door 301 can move in the front-back direction as the piston rod 304 of the cylinder moves, thereby changing the relative position of the mother compartment door 301 and the daughter compartment door 302 in the front-back direction.

[0037] Furthermore, each of the mother and daughter door assemblies on the feeding bin body 100 is equipped with an electromagnetic latch lock on both the front and rear sides. The mother door 301 and the daughter door 302 have pin holes that cooperate with the electromagnetic latch locks. Specifically, as shown in Figure 3, each mother and daughter door assembly is provided with an electromagnetic latch lock 104 and an electromagnetic latch lock 206 on its front and rear sides, respectively. In the mother and daughter door assembly at the upper end of the material compartment unit, the daughter door 302 is provided with a pin hole 105 that matches the electromagnetic latch lock 104, and the mother door 301 is provided with a pin hole 207 that matches the electromagnetic latch lock 206.

[0038] When the electromagnetic bolt lock 104 is aligned with the pin hole 105, the electromagnetic bolt lock 104 can be activated and inserted into the pin hole 105 (at this time, the sub-door is in a locked state), thus locking the sub-door 302 and preventing it from moving. Similarly, when the electromagnetic bolt lock 106 is aligned with the pin hole 107, the electromagnetic bolt lock 106 can be activated and inserted into the pin hole 107 (at this time, the main door is in a locked state), thus locking the main door 301 and preventing it from moving. Through the cooperation of the electromagnetic bolt locks and the pin holes, the main door 301 and the sub-door 302 can be locked.

[0039] Therefore, when only the sub-door 302 is locked by the electromagnetic bolt lock 104 (i.e., electromagnetic bolt lock 104 is inserted into pin hole 105, but electromagnetic bolt lock 106 is not inserted into pin hole 107), after the cylinder piston rod 304 extends or retracts, the unlocked main door 301 connected to the cylinder body can be controlled to open or close. Similarly, when only the main door 301 is locked by the electromagnetic bolt lock 106 (i.e., electromagnetic bolt lock 106 is inserted into pin hole 107, but electromagnetic bolt lock 104 is not inserted into pin hole 105), after the cylinder piston rod 304 extends or retracts, the sub-door 302 connected to the piston rod can be controlled to open or close.

[0040] Preferably, a sub-door stop block 103 and a mother door stop block 108 are respectively provided on the front side of the sub-door 302 and the rear side of the mother door 301. In this embodiment, the sub-door stop block 103 is used to prevent the sub-door 302 from moving further; the mother door stop block 108 is located at the end of the guide rod 102 and is used to prevent the mother door 301 from moving further. At the same time, the guide rod 102 is connected to the upper end of the feeding bin body 100 through the mother door stop block 108. As shown in Figure 2, the sub-door stop block 103 and the mother door stop block 108 are located at the upper end of the feeding bin body 100.

[0041] When the sub-door 302 abuts against the sub-door stop block 103, it indicates that the sub-door 302 has closed and moved into position. At this time, the electromagnetic bolt lock 104 and the pin hole 105 are aligned. Similarly, when the main door 301 abuts against the rear main door stop block 108, it indicates that the main door 301 has closed and moved into position. At this time, the electromagnetic bolt lock 2 106 and the pin hole 2 107 are aligned.

[0042] Preferably, magnetic sensors or displacement sensors can be installed on the front side of the sub-door 302 and the rear side of the mother door 301 respectively to acquire displacement data of the sub-door 302 and the mother door 301.

[0043] The magnetic sensor or displacement sensor, the door drive cylinder, the linear drive device 201, the electromagnetic pin lock 106 and the electromagnetic pin lock 104 can be connected to the PLC control system. The PLC control system coordinates the operation of each component and controls the opening and closing of the corresponding material compartment door.

[0044] Each material compartment can be used to feed different materials. Depending on the type of material to be fed, different parent and child compartment door components can be selected to open the feeding port of the corresponding material compartment.

[0045] In this embodiment, an integrated slide gate valve is connected to the lower end of the feeding hopper body 100 for opening and closing the discharge ports of each material compartment.

[0046] Specifically, the integrated slide gate valve employs a modular design, with six valve plates integrated within the same valve body frame, rather than using separate connecting frames for each valve plate, thus saving space and cost. In the integrated slide gate valve, each valve plate is controlled by an independent linear drive device, and rubber sealing strips are installed between the valve plates to prevent material leakage. The valve body frame is aligned with the lower outlet of the feeding hopper, achieving precise docking between the material compartment and the slide gate valve.

[0047] This invention proposes a storage door control scheme with high space utilization and compact structure. By using a single cylinder to drive two storage doors and an integrated slide gate valve design, it significantly reduces equipment costs and maintenance difficulty.
