Description

Technical Field

[0001] This application relates to the field of grain storage equipment technology, and in particular to a plate-type anti-grading device. Background Technology

[0002] In the storage of corn and soybeans, shallow circular silos are widely used due to their high space utilization and good storage performance. However, existing shallow circular silo center-pipe grain spreading equipment has significant drawbacks. Traditional center-pipe grain spreading methods can only spread grain at a single location within the silo. This leads to natural grading of corn and soybeans during accumulation due to differences in particle size, shape, and density, under gravity and flow. Larger grains tend to accumulate near the silo walls, while smaller particles and lighter impurities gather in the center. This grading severely affects the storage quality of the grain, easily causing problems such as poor ventilation and uneven pesticide distribution during subsequent ventilation and fumigation operations, increasing the risk of mold and pests, and reducing the safety and quality of stored grain. Furthermore, spreading grain at a single location can also lead to uneven grain accumulation within the silo, affecting the stability of the silo structure and increasing maintenance costs. Utility Model Content

[0003] In order to reduce the grading of corn and soybeans during storage, this application provides a plate-type anti-grading device.

[0004] The insert-type anti-grading device provided in this application adopts the following technical solution: it includes a feeding hopper fixed to the top of the silo, a chute pipe is provided at the bottom of the feeding hopper, and an inclined distribution chute is connected to the side of the feeding hopper. The distribution chute is retractable, and there are multiple distribution chutes that are evenly distributed at intervals along the side of the feeding hopper. An adjustable gate is provided on the distribution chute to adjust the amount of grain fed, forming a structure in which grain enters the feeding hopper and is discharged evenly in the silo through multiple distribution chutes and the chute pipe. A winding mechanism for driving the gate to move is provided on the silo wall, and a hanger connected to the top of the silo is provided at the end of the distribution chute away from the feeding hopper.

[0005] Optionally, the winding mechanism includes a wire rope connected to the gate, with a handwheel at the end of the wire rope away from the gate for moving the wire rope. The material distribution chute is provided with a discharge trough for moving the gate, and a tension spring connected to the gate is provided on the material distribution chute, forming a structure in which the gate closes the material distribution chute under normal conditions due to the tension spring. The side wall of the feed hopper is provided with a guide frame for the wire rope to pass through and for moving the gate along the discharge trough.

[0006] Optionally, a fixed support is provided on the platform, and a drum for winding and unwinding the wire rope is rotatably connected to the fixed support. The drum is connected to a speed reducer, and a sleeve is provided on the outside of the wire rope.

[0007] Optionally, the suspension includes a fixing ring fixed to the material distribution chute, a hook on the top of the silo, a rope passing through the hook and connected to the fixing ring, and the rope length is adjustable.

[0008] Optionally, the material distribution chute is set at a 30-degree angle to the underpass corridor.

[0009] In summary, this application includes the following beneficial technical effects:

[0010] 1. Multiple feed chutes enable simultaneous unloading of grain at multiple locations within the warehouse, effectively avoiding grain grading caused by spillage at a single location. By precisely adjusting the gate opening, the grain intake of each feed chute is ensured to be consistent, resulting in uniform grain accumulation and improved storage quality and stability.

[0011] 2. The winding mechanism uses a handwheel, wire rope and tension spring. The operator can turn the handwheel to flexibly adjust the gate opening to adapt to different grain unloading conditions. The sleeve on the wire rope reduces wear during winding and unwinding and extends its service life.

[0012] 3. The telescopic structure of the material distribution chute is connected to the top of the silo by an adjustable length hanger, which ensures the stability and fixation of the material distribution chute and can be adjusted as needed;

[0013] 4. The combination of drum, reducer and handwheel on the fixed bracket reduces the labor intensity of operators and facilitates the winding and unwinding of wire rope. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a plug-in type anti-grading device. For example... Figure 1 and 2As shown, the hopper 2 is fixed to the top of the silo 1. When used in a new silo, the top of the silo 1 is pre-embedded with steel plates to fix the hopper 2 as required. When used for the renovation of an old silo, the hopper 2 is hoisted to the top of the silo 1 using chemical bolts. The bottom of the hopper 2 is connected to a chute pipe 3, and the side of the hopper 2 is connected to an inclined distribution chute 4, which is set at a 30-degree angle to the underpass. The distribution chute 4 is telescopic, and there are six distribution chutes 4, which are evenly distributed along the side of the hopper 2. An adjustable feed gate 5 is slidably connected to the distribution chute 4, and a discharge chute is provided on the distribution chute 4 for the gate 5 to move, forming a structure in which grain enters the hopper 2 and is discharged evenly in the silo body through multiple distribution chutes 4 and chute pipes 3. A tension spring 603 is provided on the distribution chute 4 and connected to the gate 5. Under normal conditions, the gate 5 relies on the tension spring 603 to close the distribution chute 4. A winding mechanism 6 is installed on the hopper wall to move the gate 5. The winding mechanism 6 includes a steel wire rope 601 connected to the gate 5. A handwheel 602 is installed at the end of the steel wire rope 601 away from the gate 5 to move the steel wire rope 601. A guide frame 604 is bolted to the side wall of the feed hopper 2 for the steel wire rope 601 to pass through and for moving the gate 5 along the discharge chute. The guide frame 604 has a "U" shaped structure and a through hole that runs through its thickness. The end of the material distribution chute 4 furthest from the feed hopper 2 is provided with a hanger 7 connected to the top of the silo 1. The hanger 7 includes a fixing ring 701 fixed on the material distribution chute 4. The fixing ring 701 is located at the end of the material distribution chute 4 furthest from the feed hopper 2. A hook 702 is threaded onto the top of the silo 1. A rope 703 passes through the hook 702 and is connected to the fixing ring 701. Fixing holes for fixing the rope 703 are provided at the two corners of the fixing ring 701. The length of the rope 703 is adjustable.

[0020] In one embodiment, according to the appendix Figure 3 As shown, a fixed bracket 606 is bolted to the platform 605. A drum for winding and unwinding each wire rope 601 is rotatably connected to the fixed bracket 606. A reducer for driving the drum to rotate is bolted to the fixed bracket 606. The reducer is existing technology. The operator can choose to manually rotate the handwheel 602 to drive the drum to rotate or choose to drive the drum to rotate with the reducer. A sleeve 609 is fitted over the wire rope 601.

[0021] The implementation principle of the insert-type anti-grading device in this application embodiment is as follows: The feed hopper 2 is firmly fixed to the top of the silo 1, ensuring accurate installation and tight connection with the silo body. A distribution chute 4 is installed, connected to the hook 702 on the top of the silo 1 using a hanger 7. The length of the rope 703 is adjusted to achieve a suitable inclination angle for the distribution chute 4, forming a 30-degree angle with the passageway below the silo. A gate 5 is installed on the distribution chute 4 and connected to a tension spring 603, ensuring that the gate 5 normally closes the distribution chute 4 under the action of the tension spring 603. A winding mechanism 6 is installed, with a fixed bracket 606 installed on the platform 605. A drum is installed on the fixed bracket 606, connected to a reducer and a handwheel 602. One end of the wire rope 601 is connected to the gate 5, and the other end passes through the guide frame 604, is wound onto the drum, and fitted with a sleeve 609.

[0022] Start the grain conveying equipment to feed grain into the feed hopper 2. The operator selects to use the handwheel 602 or a reducer to drive the drum, winding or unwinding the wire rope 601, depending on the unloading requirements. The wire rope 601 pulls the gate 5 against the tension of the spring 603, causing the gate 5 to move along the discharge chute and open the distribution chute 4. By controlling the rotation angle of the drum, the opening of the gate 5 and the amount of grain fed into the distribution chute 4 are precisely adjusted. Grain enters the distribution chute 4 and the chute pipe 3 from the feed hopper 2. Due to the multi-position distribution and inclined setting of the distribution chute 4, the grain is evenly unloaded into the bin from multiple positions under gravity, effectively preventing grain grading. During the unloading process, the operator adjusts the opening of the gate 5 of each distribution chute 4 as needed based on the grain accumulation in the bin to ensure even grain accumulation.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
