Description

Technical Field

[0001] This utility model belongs to the field of grain storage technology, specifically relating to a dust suppression and anti-grading grain distribution device for grain storage. Background Technology

[0002] Grain placement in storage and transportation is a crucial step. However, existing grain placement devices have the following problems: First, the process of grain entering the storage facility generates a large amount of dust, resulting in high dust concentrations inside the storage area, which not only affects the health of workers but also poses safety hazards. Second, grain is prone to grading during the process, meaning that grains of different sizes are unevenly distributed within the storage area, leading to inconsistent grain quality and affecting subsequent storage and management. Furthermore, existing placement devices have low levels of automation, resulting in uneven grain distribution and increasing the workload and time costs of manual leveling. To solve these problems, there is an urgent need for a grain placement device that can effectively suppress dust, prevent grain grading, and improve the uniformity of grain placement. Utility Model Content

[0003] To address the problems of high dust concentration, uneven grain distribution, and severe grain grading during grain storage, this utility model patent aims to provide a dust suppression and anti-grading grain storage device. This device can regulate the amount of grain entering the storage, reduce the dust concentration inside the storage, improve the grading phenomenon after grain enters the storage, ensure uniform grain distribution after entering the storage, improve the mechanization level of grain storage, and reduce the labor costs of enterprises.

The dust suppression device includes a feed chute, a hopper cover, and a dust suppression hopper. The hopper cover is fixed above the dust suppression hopper, and the feed chute is connected to the dust suppression hopper through the hopper cover. The dust suppression hopper is connected to the frame through a connecting spring. A cone plug support is axially fixedly connected to the lower outlet of the feed chute, and a cone plug is fitted on the cone plug support. A material drop gap is formed between the outer wall of the cone plug and the inner wall of the dust suppression hopper.

[0005] The anti-grading grain distribution device is composed of a cone-bottomed distributing hopper. The cone-bottomed distributing hopper includes a polygonal distributing cylinder, a guide channel, and a chute. The polygonal distributing cylinder is located directly below the dust suppression hopper. The bottom of the polygonal distributing cylinder has an upward-convex cone-shaped structure. The guide channel and the chute are fixed to the outer side of the bottom of the cone-bottomed distributing hopper. Multiple partitions are evenly arranged inside the polygonal distributing cylinder, which divide the inside of the polygonal distributing cylinder into multiple material dropping spaces. The multiple material dropping spaces are connected to the guide channel and the chute in sequence.

[0006] Furthermore, a support rod is longitudinally fixed at the intersection of the partitions, and the cone plug is fixedly fitted on the support rod, with the upper end of the cone plug longitudinally slidingly fitted on the guide sleeve at the bottom of the cone plug support.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1-4 This utility model provides a technical solution for a dust suppression and anti-grading grain feeding device: Example

[0019] according to Figure 1 and Figure 2 As shown, a dust suppression and anti-grading grain feeding and distributing device consists of two parts: a dust suppression device and an anti-grading grain distributing device. The dust suppression device includes components such as a feed chute 1, a frame 2, a hopper cover 3, a connecting spring 4, a cone plug support 5, a cone plug 6, and a dust suppression hopper 7. The hopper cover 3 is bolted to the top of the dust suppression hopper 7. The feed chute 1 is bolted to the center of the hopper cover 3. The feed chute 1 is connected to the dust suppression hopper 7 through the hopper cover 3. A straight rod is horizontally welded and fixed at the lower outlet of the feed chute 1. A cone plug support 5 is axially fixed to the center of the lower part of the feed chute 1 through the straight rod. The bottom of the cone plug support 5 is connected to a guide sleeve 9. The movable set is equipped with a support rod, the lower end of which is fixedly mounted on the anti-grading grain distribution device. A cone plug 6 is fixedly mounted on the support rod, so that the cone plug 6 slides longitudinally on the cone plug support 5. The cone plug 6 is located inside the dust suppression hopper 7, and a material drop gap is formed between the outer wall of the cone plug 6 and the inner wall of the dust suppression hopper 7. When the grain falls into the dust suppression hopper, the dust suppression hopper can collect the grain. After the grain passes through the dust suppression hopper 7, it enters the cone bottom distribution hopper 8 in the form of a dense material column, avoiding the grading phenomenon caused by the free fall of the grain during the storage process.

[0020] A frame 2 is installed on the top of the grain silo. Multiple connecting springs 4 are evenly distributed longitudinally on the frame 2. The lower ends of the connecting springs 4 are suspended and fixed on the edge hooks of the dust suppression hopper 7. The dust suppression hopper 7 is connected to the frame 2 through the connecting springs 4. A guide sleeve 9 is fixedly installed at the bottom of the cone plug support 5. The upper end of the cone plug 6 is longitudinally slidably fitted into the guide sleeve 9. When there is a lot of grain in the dust suppression hopper 7, the weight of the grain can press the dust suppression hopper 7 downward. At the same time, the connecting springs 4 on the dust suppression hopper 7 provide tension to the hopper. During the downward fall of the hopper, the position of the cone plug 6 remains unchanged. At this time, the material drop gap between the dust suppression hopper and the cone plug will increase, thereby accelerating the material drop speed. By coordinating the amount of grain in the dust suppression hopper with the connecting springs, the material drop rate of the hopper can be automatically adjusted without manual intervention. Furthermore, during the up and down movement of the dust suppression hopper 7, the guide sleeve 9 and the cone plug 6 can limit the movement range of the dust suppression hopper 7, thereby limiting the adjustment range of the material drop rate of the dust suppression hopper.

[0021] The anti-grading grain distribution device is located at the lower end of the dust suppression device and is supported and fixed on the platform of the grain silo by a mounting bracket. The anti-grading grain distribution device includes a cone-bottomed distributing hopper 8, with a grain inlet 82 above the cone-bottomed distributing hopper 8. The cone-bottomed distributing hopper 8 specifically includes a polygonal distributing cylinder 85, a guide channel 83, and a chute 84. The polygonal distributing cylinder 85 is located directly below the dust suppression hopper 7, and the bottom of the polygonal distributing cylinder 85 is a convex cone structure. Multiple partitions 81 are evenly arranged inside the polygonal distributing cylinder 85, which divide the inside of the polygonal distributing cylinder 85 into multiple material dropping spaces. The multiple material dropping spaces are connected in sequence to the guide channel 83 and the chute 84. The guide channel 83 and the chute 84 are fixed to the bottom outer side of the cone-bottomed distributing hopper 8. The material dropping port of the guide channel 83 faces the center of the device below. The chute 84 is composed of three chute pipes of different lengths, with the material dropping ports facing the four sides of the device, ensuring that the grain can be evenly distributed to different positions in the silo. The lower end of the support rod is fixed at the center intersection of the partition, and multiple connecting chains are also suspended on frame 2.

[0022] In practical use, the dust suppression and anti-grading grain feeding and distribution device of this utility model allows grain to enter the dust suppression device from the feed chute 1 and fall to the top of the cone plug 6. The grain slides down along the cone surface of the cone plug 6 and the cone surface of the dust suppression hopper 7. Through the gap between the cone plug 6 and the dust suppression hopper 7, the grain enters the cone bottom distribution hopper 8 in the form of a dense material column from the discharge port of the dust suppression hopper 7. Then, the grain slides down along the cone surface of the cone bottom distribution hopper 8 and enters the guide trough 83 and the chute 84 respectively, and is finally evenly distributed to different positions in the warehouse.

[0023] When there is a lot of grain in the dust suppression hopper 7, the weight of the grain presses the dust suppression hopper 7 downwards. During the downward fall, the material drop gap between the dust suppression hopper 7 and the cone plug 6 will increase, thereby accelerating the material drop speed. When the amount of grain in the dust suppression hopper 7 gradually decreases, the connecting spring 4 will pull the dust suppression hopper 7 upwards and gradually return to its original position. During the upward movement, the material drop gap between the dust suppression hopper 7 and the cone plug 6 will decrease, thereby reducing the material drop speed. The material drop rate of the hopper is automatically adjusted by the amount of grain in the dust suppression hopper in conjunction with the connecting spring.

[0024] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
