Technical Field
[0001] The utility model belongs to the technical field of grain storage technology and relates to a shallow circular silo grain warehousing device, in particular to a combined shallow circular silo grain warehousing device. Background Art
[0002] A granary is a specialized building used to store large quantities of grain. my country is a major agricultural country with a long history of grain production and storage. This storage process places numerous performance requirements on granaries, including moisture resistance, thermal insulation, ventilation, airtightness, insect and rodent resistance, fire resistance, and earthquake resistance.
[0003] Shallow silos are a widely used type of grain silo in China. Compared to traditional square silos, shallow silos offer larger storage capacity, a higher degree of mechanization, and a smaller footprint, making them suitable for the grain storage needs of large-scale grain storage companies.
[0004] However, the current grain storage operation in shallow circular silos needs to solve three problems: (1) The automatic grading of grain caused by single-point or small-point dropping is serious, which is not conducive to grain storage; (2) The dropping of grain at high points causes a large amount of grain to break, and the increase in breakage rate is high, especially for corn after drying in the north. This problem is particularly prominent; (3) The grain surface is seriously uneven after storage, with a large height difference, which increases the subsequent closing workload and closing costs, and is prone to safety accidents such as burying people during the closing operation.
[0005] Currently, there are two main types of shallow silo loading equipment in common use: various types of distributors, including pressure-gate umbrella-shaped multi-point distributors and valve-controlled multi-point distributors; and buttress folding plate breakage reduction devices. The former can address the problems of severe grain grading and large differences in grain surface height, but it cannot solve the problem of high grain breakage and increased breakage rates caused by high-point dropouts. The latter can address the problem of increased breakage rates during grain grading, but it cannot solve the problems of severe grain grading and large differences in grain surface height.
[0006] However, to date, there has not yet been a shallow silo loading equipment that effectively and completely solves the above three problems. Summary of the Invention

[0034] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0035] Reference Figure 1 As shown, the combined shallow silo grain feeding equipment of this embodiment includes a pressure door type umbrella-shaped multi-point feeding mechanism 2, a feeding mechanism chute 4, a connecting device 5, and a folding plate vertical chute crushing reduction mechanism.
[0036] A pressure door type umbrella-shaped multi-point feeding mechanism 2 is fixedly installed below the top feeding port 1 of the shallow circular silo 3, and a folding plate vertical groove crushing reduction mechanism is installed below the pressure door type umbrella-shaped multi-point feeding mechanism 2. A connecting device 5 is installed between the two mechanisms and connected and fixed with steel components.
[0037] like Figure 2 As shown, the pressure gate type umbrella-shaped multi-point material distribution mechanism 2 is provided with a material receiving cylinder 21, an overflow cylinder 23, a material distribution plate 26, a chute interface 27 and a central discharge gate 28 in sequence from top to bottom;
[0038] The receiving barrel 21 is located below the top feed port 1 of the shallow silo 3. A spring 22, a pressure door 24 and a shaft 25 are provided in the overflow barrel 23. The spring 22 and the pressure door 24 below the spring are sleeved on the shaft 25. Under the pressure of the accumulated grain, the pressure door 24 will overcome the resistance of the spring 22 and move downward along the shaft 25, and a flow space is left between the edges of the pressure door 24 and the overflow barrel 23.
[0039] Eighteen chute connections 27 are arranged at equal angles around the circumference of the distribution tray 26, connecting to each of the eighteen distribution mechanism chutes 4. These connections can be used to open and close the distribution mechanism chutes 4 (in this embodiment, twelve long chutes and six short chutes). The chute connections 27 are flange-connected to the distribution tray 26 of the distributor. The distribution mechanism chutes 4 are positioned at an angle between 30° and 38° to the horizontal. Preferably, the distribution mechanism chutes 4 are fixed to the embedded components of the silo roof 3 with steel tie rods to ensure stability.
[0040] A central discharge port gate 28 is provided at the central discharge port below the dispensing tray 26. One side of the central discharge port gate 28 is fixedly connected to the central discharge port via a hinge, and the other side of the central discharge port gate 28 is provided with a steel wire rope 210, which is connected to a pulley 29 fixed to the side of the central discharge port. The central discharge port gate 28 can rotate around the hinge and open through the pulley 29 and the steel wire rope 210.
[0041] When the traction wire rope 210 is loosened, the central discharge gate 28 opens under the action of its own weight ( Figure 2 The center discharge opening has a large diameter (large discharge opening). When the wire rope 210 is tightened, the center discharge opening gate 28 closes, and the center discharge opening has a small diameter (small discharge opening). Grain entering the silo 3 through the 18 feeding chutes 4 and the small center discharge opening falls into 19 equal-sized areas.
[0042] like Figure 1 As shown, a folding plate vertical chute crushing reduction mechanism is installed below the pressure gate type umbrella-shaped multi-point distribution mechanism 2, and a connecting device 5 is installed between the two mechanisms. That is, a connecting device 5 is provided below the central discharge port of the pressure gate type umbrella-shaped multi-point distribution mechanism 2 and the entrance of the oblique chute 7 of the folding plate vertical chute crushing reduction mechanism. The central discharge port of the pressure gate type umbrella-shaped multi-point distribution mechanism 2 and the entrance of the oblique chute 7 of the folding plate vertical chute crushing reduction mechanism are connected by the connecting device 5.
[0043] The connecting device 5 is configured as a hollow receiving barrel, which is fixed above the two folding plate chutes (inclined chutes 7). Its function is to receive the material flowing down from the bottom of the distributor and distribute it to the two chutes (inclined chutes 7).
[0044] There is a 50 cm space between the upper end of the receiving barrel and the lower end of the pressure gate type umbrella-shaped multi-point feeding mechanism 2, which has two functions: (1) when the folding plate chute (inclined chute 7) is blocked, the material can overflow the channel; (2) this space can be used as the opening and closing space of the central blanking gate 28.
[0045] In this embodiment, the material receiving barrel of the connecting device 5 is made of a Φ500×5mm seamless steel pipe.
[0046] like Figure 1As shown, the folding plate vertical trough crushing reduction mechanism includes an inclined chute 7 located at the upper part of the shallow circular silo 3 and a folding plate vertical trough 8 uprightly arranged along the side wall of the shallow circular silo 3. The upper end of the inclined chute 7 is connected to the central discharge port of the pressure door type umbrella-shaped multi-point feeding mechanism 2, and the lower end of the inclined chute 7 is connected to the upper end of the folding plate vertical trough 8. A plurality of folding plates connected end to end are provided in the folding plate vertical trough 8. The buffering of the staggered folding plates slows down the falling speed of the grain. The lower end of the folding plate vertical trough 8 is at a certain distance from the bottom of the shallow circular silo 3, so that the grain can flow out of the folding plate vertical trough 8 from top to bottom.
[0047] Preferably, the inclined chute 7 is fixedly connected to the embedded parts on the roof of the shallow silo 3 by a steel pull rod.
[0048] The grain storage operation process using the combined shallow silo grain storage equipment of this embodiment is as follows:
[0049] 1) Front-end grain storage operation:
[0050] The wire rope 210 is loosened, and the central discharge gate 28 is opened, allowing grain to fall through the receiving barrel 21 into the overflow barrel 23. Because the annular area between the pressure gate 24 and the overflow barrel 23 is smaller than the flow area required for the current grain delivery rate, grain accumulates in the overflow barrel 23. Under the pressure of the accumulated grain, the pressure gate 24 moves downward, overcoming the resistance of the spring 22. The greater the accumulation, the greater the downward movement of the pressure gate 24. When the pressure gate 24 reaches the bell-shaped opening at the lower end of the overflow barrel 23, the annular flow area increases, and the delivery rate also increases. When the annular flow area increases to the flow area required for the incoming grain delivery rate, the grain accumulation height in the overflow barrel 23 remains constant. The pressure on the pressure gate 24 balances the resistance of the spring 22, and the grain falls evenly along the annular discharge opening. As the grain delivery rate increases or decreases, the grain accumulation height in the overflow barrel 23 changes accordingly, and the pressure gate 24 moves downward or upward accordingly, increasing or decreasing the annular flow area accordingly, until it reaches a stable state.
[0051] Since the central discharge gate 28 is open, the area of the central discharge opening is equal to or greater than the flow area required for the incoming grain. Therefore, all the incoming grain passes through the central discharge opening of the pressure gate umbrella-shaped multi-point distribution mechanism 2 and enters the two inclined chutes 7 of the folding plate vertical trough crushing mechanism. It then flows evenly into the two folding plate vertical troughs 8 installed on the wall. The folding plate's buffering effect slows down the fall and the grain flows out of the folding plate vertical trough 8 from the bottom to the top of the grain outlet at the bottom of the folding plate vertical trough 8, forming two incomplete cones that are constantly expanding with the folding plate vertical trough 8 as the axis. When the top of the cone rises to the top of the folding plate vertical trough 8, the cone-shaped grain blocks the inclined chute 7, and the incoming grain no longer flows down the inclined chute 7. At this time, the front-stage grain feeding is completed ( Figure 3 During the entire feeding process, the grain falls slowly, which can avoid the grain from being broken by freely falling from a high place.
[0052] If the grain continues to be fed in, the grain will overflow from the top of the inclined chute 7.
[0053] 2) Later stage grain storage operation:
[0054] When the two inclined chutes 7 of the folding plate vertical chute crushing mechanism are blocked, the wire rope 210 is tightened, the central discharge opening gate 28 is closed, and the central discharge opening is transformed into a small central discharge opening. The incoming grain falls through 18 distribution mechanism chutes 4 and the central discharge opening, a total of 19 discharge outlets. Due to the material balancing function of the pressure door umbrella-shaped multi-point distribution mechanism 2 and the natural flow of grain from high to low, when the grain storage operation is completed, 19 small grain piles with basically equal height differences and uniform distribution are formed on the grain surface. This can effectively solve the problem of heavy workload and unsafe conditions of automatic grain grading and unloading. Figure 4 )
[0055] (Alternatively, after the two inclined chutes 7 of the folding plate vertical chute crushing mechanism are blocked, the incoming grain can be allowed to overflow from the top of the two inclined chutes 7 for a period of time before closing the central blanking gate 28).
[0056] After the grain storage operation is completed, the bottom grain outlet of the folding plate vertical groove 8 is opened to empty the grain accumulated in the groove.
[0057] The above embodiments are only for illustrating the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention; any technology not involved in the present invention can be realized by existing technology.
