Description

Technical Field

[0001] This invention relates to the field of bulk grain storage, and more particularly to a bulk multi-story warehouse capable of unpowered unloading. Background Technology

[0002] Multi-story warehouses are a special type of storage facility, consisting of multiple layers of grain storage structure. Compared to traditional single-story warehouses, they offer advantages such as higher land utilization and larger storage capacity. Existing multi-story warehouses include columns and walls, with floor slabs fixed to the columns and walls to divide the warehouse interior into at least two layers. The top of the warehouse is equipped with inlet equipment, which typically includes horizontally and vertically arranged bulk grain conveyors. The outlet of the inlet equipment is connected to a chute leading to each floor. To ensure that the chute is not deformed by the bulk grain when it is full, it needs to be fixed to the corresponding column. The floor slabs have grain leakage outlets at the corresponding chute locations.

[0003] During the grain loading process, the bulk grain is lifted to the top of the multi-story warehouse by the hoisting equipment, and then transported to the respective discharge chutes by the loading equipment, and then to the corresponding floor slabs by the corresponding discharge chutes. During the grain unloading process, the bulk grain from the first floor is first transported out by the unloading equipment, and then the bulk grain from the second floor falls back to the first floor through the grain discharge outlet, and then the bulk grain from the first floor is transported out by the unloading equipment. Similarly, when the bulk grain from the third floor needs to be unloaded, it needs to be first placed on the floor slab of the second floor, then placed on the floor slab of the first floor, and then the bulk grain from the first floor is transported out by the unloading equipment.

[0004] While existing multi-story warehouses offer greater storage capacity than single-story warehouses, they also have significant drawbacks: 1. Whether loading or unloading, the storage space on each floor must operate in a specific order. Bulk grains must be loaded or unloaded floor by floor, which is unsuitable in certain situations. For example, if the first and second floors contain different grains—wheat on the first floor and soybeans on the second—requiring the removal of bulk grains from the second floor must first remove the bulk grains from the first floor. If only soybeans need to be removed... 1. The existing multi-story warehouse structure leads to a huge waste of labor; 2. In the current technology, the location of the grain outlet is limited by the position of the feeding chute. During the unloading operation, a grain pit is formed around the grain outlet. Not all the grain can fall into the grain outlet. At this time, it is necessary to use the corresponding grain conveying equipment to send all the loose grain around the grain pit into the grain outlet. In specific operation, the grain conveying equipment needs to be hoisted to the second or third floor for operation. After the operation is completed, the grain conveying equipment is hoisted out of the grain warehouse. This is commonly known as powered unloading, which is very time-consuming and labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to provide a bulk grain warehouse that can be opened without power, so as to solve the technical problem in the prior art that bulk grain must be opened layer by layer, which makes it impossible to open bulk grain from a specific floor individually.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution for a bulk grain warehouse capable of unloading without power, as follows:

[0007] A bulk grain storage building capable of unpowered unloading includes a storage body, within which one or at least two storage units arranged sequentially in a left-right direction are disposed. Each storage unit comprises at least two vertically arranged storage spaces. A top equipment layer is provided at the top of each storage unit. Each storage space has a top plate and a bottom plate at its upper and lower ends, respectively. A loading space for grain trucks to travel in a forward-backward direction is provided on the lower side of the bottom storage space. An intermediate equipment layer is formed between the bottom and top plates of two adjacent storage spaces. Each top plate has an inlet for grain discharge and an upper chute perforation, and each bottom plate has an outlet for grain discharge and a lower chute perforation. A discharge chute is fixed to the wall of each storage space, with its upper end extending through the corresponding upper chute perforation. The lower end of the chute protrudes through the corresponding lower chute perforation. Two adjacent storage spaces in the vertical direction are defined as the upper storage space and the lower storage space, respectively. A distributor with two inlets and two outlets is installed at the grain discharge port of the upper storage space. The two inlets of the distributor are connected to the grain discharge port of the upper storage space and the lower end of the discharge chute, respectively. One of the outlets of the distributor is connected to the upper end of the discharge chute of the lower storage space, and the other outlet of the distributor is connected to the grain discharge port of the lower storage space. The lower end of the discharge chute of the lowest storage space is connected to the grain discharge port of the lowest storage space. A bulk grain conveying device for feeding grain to the upper end of the discharge chute and the grain discharge port of the highest storage space is installed in the top equipment layer.

[0008] Furthermore, the walls of each storage space are hollow.

[0009] Furthermore, there are multiple storage units, which are arranged sequentially in the left-right direction. The bulk grain conveying equipment includes one or at least two bulk grain conveyors for conveying bulk grain in the left-right direction to the upper end of the corresponding discharge chute and the grain inlet.

[0010] Furthermore, the bulk grain warehouse includes two rows of storage units arranged sequentially in the front-to-back direction. Each storage unit has a square cross-section. Two adjacent storage units in the front-to-back direction share a storage wall; two adjacent storage units in the left-to-right direction also share a storage wall.

[0011] Furthermore, each storage space has at least two grain-leaking cones spaced apart in the left-right direction on its floor. The grain outlet is located at the bottom of the grain-leaking cones. The cone wall of the leftmost grain-leaking cone extends to the left wall of the storage space, and the cone wall of the rightmost grain-leaking cone extends to the right wall of the storage space. The distance between the cone walls of two adjacent grain-leaking cones is 0.5~1.2m.

[0012] Furthermore, the grain leakage cone in the lower storage space is located directly below the corresponding grain leakage cone in the upper storage space.

[0013] Furthermore, the lower end of the feeding chute passes through the corresponding lower chute perforation and then runs along the outer wall of the grain-leaking cone to the corresponding distributor.

[0014] The beneficial effects of this invention are as follows: The bulk grain storage building of this invention can realize the feeding and discharging of grain in specific storage spaces. For example, when grain needs to be discharged from the uppermost storage space, the grain is discharged from the discharge port of the uppermost storage space and enters the distributor. Then, the distributor distributes the grain to the discharge chute of the lower storage space. The grain is then transported downward through the discharge chute of the lower storage space and finally falls into the corresponding grain loading car through the discharge port of the lowermost storage space. This realizes the unpowered discharge of grain from the designated storage space, saving time and effort. Similarly, the feeding of grain in a specific storage space can also be realized by using the cooperation of the discharge chute and the distributor. For example, when the bulk grain is transported to the upper end of the discharge chute of the uppermost storage space, the bulk grain is transported to the corresponding distributor through the discharge chute. It does not need to pass through the inner cavity of the uppermost storage space, and the feeding of the corresponding storage space can be completed, meeting the storage needs of different grain types.

[0023] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0024] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0025] Example 1 of the present invention is a bulk warehouse capable of unpowered unloading. Figures 1-5 As shown: The bulk storage warehouse 1 comprises two rows of storage units arranged in a front-to-back direction, and each row of storage units includes multiple storage units 2 arranged sequentially in a left-to-right direction. Each storage unit 2 includes two layers of storage space arranged vertically, and each storage space is enclosed by a top plate 5, a bottom plate 6, and storage walls 10 surrounding the top and bottom plates. In this embodiment, the cross-section of each storage space is square, and the storage walls 10 are all hollow. Two adjacent storage units in the front-to-back square structure share one storage wall, and two adjacent storage units in the left-to-right direction also share one storage wall.

[0026] A top equipment layer 7 is provided on the top of the storage unit. Two adjacent storage spaces in the vertical direction are defined as the upper storage space 3 and the lower storage space 4. Since each storage unit includes only two storage spaces in this embodiment, the upper storage space is the top storage space, and the lower storage space is the bottom storage space. Item 8 in the figure represents the roof.

[0027] In this embodiment, a grain loading space 17 is provided on the lower side of the bottom storage space, i.e., the lower storage space, for the grain loading vehicle 19 to travel in the front-to-back direction. An intermediate equipment layer 18 is formed between the bottom plate 6 and the top plate 5 of two adjacent storage spaces. Each space top plate is provided with a grain inlet 15 and an upper chute through hole. Each space bottom plate is provided with a grain outlet 14 and a lower chute through hole. Each storage space wall is fixed with a discharge chute 16. The upper end of the discharge chute 16 is through the corresponding upper chute through hole, and the lower end of the discharge chute 16 is through the corresponding lower chute through hole.

[0028] A first distributor 13 with two inlets and two outlets is installed at the grain discharge port of the upper storage space. The two inlets are designated as the first inlet and the second inlet, and the two outlets are designated as the first outlet and the second outlet. The first inlet is connected to the grain discharge port 14 of the upper storage space, and the second inlet is connected to the lower end of the discharge chute 16 of the upper storage space. The first outlet is connected to the grain discharge port 15 of the lower storage space via a pipe, and the second outlet is connected to the upper end of the discharge chute of the lower storage space. The distributor is existing technology and can perform the following functions: material enters through the first inlet and is discharged through either the first or the second outlet; or material enters through the second inlet and is discharged through either the first or the second outlet.

[0029] The lower end of the discharge chute of the lowest storage space is connected to the grain outlet 14 of the lowest storage space. The top equipment layer is equipped with a bulk grain conveying device for feeding grain to the upper end of the discharge chute of the uppermost storage space and the grain inlet.

[0030] The bulk grain conveying equipment includes a first bulk grain conveying device corresponding to one row of storage units and a second bulk grain conveying device corresponding to another row of storage units. Each bulk grain conveying device includes two bulk grain conveyors 9 for conveying bulk grain from right to left. The two bulk grain conveyors 9 are referred to as the left bulk grain conveyor and the right bulk grain conveyor, respectively. In this embodiment, both the left bulk grain conveyor and the right bulk grain conveyor are conveying augers. The feed end at the right end of the left bulk grain conveyor is located below the discharge end at the left end of the right bulk grain conveyor. The right bulk grain conveyor can convey the bulk grain to the right end of the left bulk grain conveyor, and then be conveyed from right to left by the left bulk grain conveyor. The left bulk grain conveyor and the right bulk grain conveyor can transport the bulk grain to the uppermost storage space, i.e., the grain inlet or the upper end of the discharge chute of the upper storage space. In other embodiments of the present invention, the two rows of storage units may also share a single bulk grain conveying device, for example, by connecting a bulk grain conveyor that delivers grain to another storage unit to the left bulk grain conveyor and the right bulk grain conveyor.

[0031] Each storage space has two grain-discharging cones 12 spaced apart along a left-right direction on its floor. The grain outlet is located at the bottom of the grain-discharging cone 12. The leftmost grain-discharging cone 12 extends to the left wall of the storage space, and the rightmost grain-discharging cone extends to the right wall of the storage space. The distance between the cone walls of two adjacent grain-discharging cones is 1m. In other embodiments of the present invention, the distance between the cone walls of two adjacent grain-discharging cones can also be 0.5m, 1.2m, or other values ​​between 0.5m and 1.2m.

[0032] The grain discharge cone 12 in the lower storage space is located directly below the corresponding grain discharge cone in the upper storage space. The lower end of the discharge chute passes through the corresponding lower chute perforation and then runs along the outer wall of the grain discharge cone to the corresponding distributor.

[0033] This invention can realize grain feeding operations in a specified storage space within a specified storage unit, and can also realize non-powered grain discharging operations in a specified storage space within a specified storage unit.

[0034] Taking the lower storage space of a certain storage unit (hereinafter referred to as the target storage unit) as an example, the bulk grain conveying equipment located on the top equipment layer transports the bulk grain to the upper end of the discharge chute of the upper storage space of the target storage unit. Then, it flows downward along the upper end of the discharge chute of the upper storage space by gravity to the corresponding distributor, flows through the first discharge port of the distributor to the corresponding grain inlet, and then falls into the lower storage space of the target storage unit. Taking the grain discharge from the upper storage space of the target storage unit as an example, the grain discharge port on the bottom plate of the upper storage space of the target storage unit opens, and the loose grain in the upper storage space enters the distributor through the grain discharge port. Then, it flows through the second discharge port of the distributor to the discharge chute of the lower storage space of the target storage unit, and then flows through the discharge chute to the grain discharge port of the lower storage space, and then falls into the grain loading car in the grain loading space. After the grain loading car is full, it can drive away directly. During discharge, the grain leakage cone at the bottom of the corresponding storage space can achieve almost complete automatic discharge of grain. The small amount of loose grain between the two grain leakage cones can be manually pushed into the grain leakage cone by the workers through the inspection door 11 after the automatic discharge ends. This can realize the entry and unpowered discharge operations of the designated storage space of the target storage unit. In other embodiments of the present invention, the adjacent cone surfaces of two adjacent grain leakage cones can also be connected together, so as to realize the unpowered discharge of all bulk grains in the corresponding storage space.

[0035] Of course, if the upper and lower storage spaces of the corresponding target storage unit store the same type of bulk grain, and the target storage unit is completely empty, the bulk grain in the lower storage space is directly discharged to the loading truck through the discharge outlet, while the bulk grain in the upper storage space flows through the distributor, the first distributor outlet of the distributor to the lower storage space, and then flows to the loading truck through the discharge outlet of the lower storage space. Figure 2 As shown, Figure 2 The middle arrow indicates the direction of bulk grain flow.

[0036] The hollow structure of the silo not only ensures the structural strength of the silo but also has excellent airtight and heat insulation performance; it enables unpowered silo opening and closing, eliminating the need for silo bottom opening equipment, reducing energy consumption, saving energy and equipment costs; and mechanized silo opening and closing can maximize the saving of human resources.

[0037] Example 2 of a bulk warehouse capable of unpowered unloading: Figure 6 As shown, Example 2 differs from Example 1 in that, in this example, each storage unit has six grain discharge cones 12 at the bottom of its storage space. When the cross-sectional size of the storage space is large, multiple grain discharge cones can achieve rapid grain discharge operations. Item 20 in the figure represents an air outlet pipe. Item 16 represents a chute for feeding grain into the lower storage space; item 21 represents a chute for discharging grain from the upper storage space, also known as an outlet chute.
