Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for grain storage, specifically relating to a novel silo grain feeding device with adjustable folding plate angle and a wall-supporting and crushing device. Background Technology

[0002] Currently, the construction height of domestic silos typically exceeds 30 meters. To effectively reduce grain breakage during the feeding process and prevent automatic grain grading, most silos employ buttress-mounted folding chutes for grain feeding. In this feeding method, the angle of the buttress folding plates is fixed during design and installation and cannot be changed. However, different types of grain require different folding plate angles to achieve the best breakage reduction effect. In practical applications, the folding plate angle of the buttress-mounted chutes cannot be adjusted in real time according to the specific material characteristics (moisture, bulk density, etc.) and processing requirements of the grain, making it difficult for the buttress-mounted folding chutes to achieve the best breakage reduction effect. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that the fixed angle of the folding plate in the existing silo grain feeding buttress chute device cannot be adjusted in real time according to different material characteristics, resulting in poor grain breakage reduction effect. This invention proposes a new type of silo grain feeding buttress breakage reduction device with adjustable folding plate angle. Through the adjustable folding plate angle design, the folding plate angle can be adjusted according to different grain types, thereby significantly reducing the grain breakage rate. Furthermore, the design of the movable plate makes the grain pile distribution more uniform and reduces the difficulty of leveling the silo.

[0004] To achieve the above objectives, the technical solution adopted is:

[0007] The grain inlet chute is inclinedly installed at the upper end of the fixed support, and a first grain discharge hole is opened at the end of the grain inlet chute.

[0008] The buttress chute is arranged in a zigzag shape from top to bottom inside the fixed support, and the topmost part receives the grain flowing out from the first grain discharge hole of the inlet chute; the buttress chute is divided into multiple sections, and each section of the buttress chute includes a folded plate hinged to the fixed support, the angle of which can be adjusted according to different grain varieties.

[0009] And an actuator, which is mounted on the fixed bracket, for driving the folding plate to rotate.

[0010] According to the present invention, the novel silo grain feeding wall support and crushing device with adjustable folding plate angle further comprises a fixed support that is a rectangular frame welded from four angle steels and two I-beams. The two I-beams are respectively set between the upper ends of the two angle steels on the wall side and between the upper ends of the two angle steels away from the silo body; an actuator mounting platform is set between the two I-beams.

[0011] According to the present invention, a novel silo grain feeding buttress and crushing device with adjustable folding plate angle is further described, wherein each buttress chute is a trough formed by a front baffle, a rear baffle, and two side baffles. The front baffle is welded between two angle steels away from the silo body, and the rear baffle is welded between two angle steels on the wall side, and the front baffle and the rear baffle have a height difference; the two side baffles are located between the front baffle and the rear baffle, and are respectively welded to the two front angle steels and the two rear angle steels.

[0012] According to the present invention, the novel silo grain feeding support wall crushing device with adjustable folding plate angle further comprises, wherein the folding plate is the bottom surface of each section of the support wall chute, and its lower edge forms a second grain discharge hole with the front baffle and the two side baffles.

[0013] According to the present invention, the novel silo grain feeding wall support and crushing device with adjustable folding plate angle further includes an actuator comprising an electric push rod with self-locking function and an intelligent control module for controlling the stroke of the electric push rod.

[0036] The following description, in conjunction with the accompanying drawings of specific embodiments of the present invention, will provide a clear and complete illustration of exemplary solutions. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art.

[0037] like Figure 1 and Figure 2 As shown in the figure, this embodiment discloses a novel silo grain inlet support wall crushing device with adjustable folding plate angle, including a fixed support 1, an inlet chute 2, a support wall chute 3, and an actuator. The wall-facing side of the fixed support 1 is welded and fixed to the silo body embedded parts. The inlet chute 2 is inclinedly arranged at the upper end of the fixed support 1, with its first end communicating with the silo grain inlet and its end having a first grain discharge hole. Grain enters the silo from the grain inlet and flows down the inlet chute 2 through the first grain discharge hole into the support wall chute 3. The support wall chute 3 is arranged in a zigzag shape from top to bottom inside the fixed support 1. The support wall chute 3 is divided into multiple segments, each of which includes a folding plate 301 hinged to the fixed support 1. The angle of the folding plate 301 can be adjusted according to different grain varieties. This adjustable angle folding plate 301 design can adapt to the inlet of different grain varieties and achieve the best crushing effect. The actuator is installed on the fixed support 1 and is used to drive the folding plate 301 to rotate.

[0038] The fixed support 1 is a rectangular frame welded from four angle steels 101 and two I-beams (or L-shaped steels 102). The two I-beams are welded between the upper ends of the two angle steels 101 on the wall side and between the upper ends of the two angle steels 101 away from the silo body. An actuator mounting platform 5 is welded between the two I-beams, and reinforcing ribs are added to the bottom surface to support the actuator. Because the fixed support 1 is relatively high, it is not convenient to transport and move it into the silo. Therefore, the fixed support 1 can be transported to the silo in multiple sections, hoisted and spliced, and then welded into a whole.

[0039] Each section of the buttress chute 3 is a trough body surrounded by a front baffle 302, a rear baffle 303, and two side baffles 304. The front baffle 302 is welded between two angle steels 101 away from the silo body, and the rear baffle 303 is welded between two angle steels 101 on the wall side. There is a height difference between the front baffle 302 and the rear baffle 303. The two side baffles 304 are located between the front baffle 302 and the rear baffle 303, and are welded to the two front angle steels 101 and the two rear angle steels 101, respectively. The multi-section buttress chute 3 guides the grain flow, reduces impact force, lowers the breakage rate, and reduces automatic grading.

[0040] The folding plate 301 forms the bottom surface of each section of the buttress chute 3 and is always in close contact with the two side baffles 304, preventing it from coming off (this limit position can be determined by a limit switch). Otherwise, the grain would flow out through the gaps, rendering the chute ineffective. The lower edge of the folding plate 301, together with the front baffle 302 and the two side baffles 304, forms a second grain discharge hole 305, from which the grain flows to the next section of the buttress chute 3.

[0041] The actuator includes an electric push rod 401 with a self-locking function and an intelligent control module that controls the stroke of the electric push rod 401. The intelligent control module automatically controls the electric push rod 401 based on the characteristics of the grain material (moisture, bulk density, etc.) to adjust the optimal angle of the folding plate 301. Of course, the rotation angle of the folding plate 301 can also be manually controlled and adjusted. The output end of the electric push rod 401 is connected to two movable plates 6 that can move up and down. The two movable plates 6 are respectively arranged on both sides of the fixed bracket 1, and multiple pairs of transverse strip grooves 601 are spaced apart on the two movable plates 6.

[0042] like Figure 3 and Figure 5 As shown, an adjusting rod 306 is provided at the bottom of the folding plate 301, and the adjusting rod 306 passes through a pair of strip-shaped grooves 601. The electric push rod 401 drives the two movable plates 6 to move up and down, and the adjusting rod 306 moves left and right in the strip-shaped grooves 601, thereby driving the folding plate 301 to rotate around the hinge point 307 to achieve angle adjustment.

[0043] Preferably, multiple third grain discharge holes 602 are vertically provided on the two movable plates 6. When the grain exceeds the height of the two side baffles 304 of the buttress chute 3, the grain will flow outward from the third grain discharge holes 602 to achieve grain distribution. The setting of the third grain discharge holes 602, while ensuring strength, makes the grain pile distribution more uniform, avoids the formation of cavities due to obstruction, and ensures the safety of manual leveling operations.

[0044] Each section of the buttress chute 3 has two side baffles 304 and two limit wheels 7 on the outer wall of the inlet chute 2. The distance between the two limit wheels 7 is the same as the width of the movable plate 6, ensuring that the movable plate 6 moves up and down along the set track while preventing the movable plate 6 from swaying left and right, which would affect the angle adjustment accuracy. After the angle of the folding plate 301 is adjusted, the movable plate 6 is locked by the self-locking function of the electric push rod 401 and the limit wheels 7, preventing the angle of the folding plate 301 from changing during the grain feeding process.

[0045] In addition to the above structure, the device also includes a limit switch. The limit switch is installed above the actuator mounting platform 5 to limit the amplitude of the vertical movement of the movable plate 6, ensuring that the angle adjustment of the folding plate 301 is at the maximum or minimum limit, avoiding excessive movement of the electric push rod 401 that could damage the equipment, and also preventing the folding plate 301 from detaching from the two side baffles 304 of the buttress chute 3, thus causing the chute function to fail.

[0046] like Figure 4 As shown, angle scale lines 8 are provided on the two side baffles 304 of the lowest section of the buttress chute 3 to display the rotation angle of the folding plate 301.

[0047] The working principle is as follows:

[0048] Based on the characteristics of the grain entering the warehouse, the angle of the folding plate 301 is automatically adjusted via an intelligent control module, or the angle can be adjusted manually by starting and stopping the electric push rod 401. Upon receiving a command, the electric push rod 401 begins to move the two movable plates 6 up and down, while the adjusting rod 306 moves left and right within the strip groove 601, thereby causing the folding plate 301 to rotate around the hinge point 307. When the set angle is reached, the electric push rod 401 stops working and self-locks to maintain the angle of the folding plate 301, thus achieving adjustable folding plate angle. This invention enables adjustable folding plate angle 301 to adapt to different grain types during grain feeding, maximizing the crushing reduction effect.
