Technical Field

[0001] The utility model relates to the technical field of grain production, in particular to a screening device for grain production. Background Art

[0002] Grain refers to the general term for various plant seeds used in cooking food. After the grain is harvested, it is often mixed with impurities such as stones and sand. Therefore, a screening machine is needed to separate large impurities such as stones and sand from the grain, otherwise it will affect the quality of the processed product. The screening machine generally generates vibration and then screens through a screen.

[0003] According to the patent with announcement number CN112090728A, a screening device for grain production and processing is proposed. The screening device for grain production and processing can generate vibration when in use by arranging a vibration motor on the frame. By arranging a shaking component, the screen can shake when vibration occurs, which can further improve the screening effect. Therefore, the screening efficiency of grain is accelerated under the action of gravity and airflow. The screening efficiency is high, the operation is simple, and multiple screenings ensure the screening effect, thereby improving the grain classification and collection function.

[0004] However, when the screening device for grain production and processing is screening the grain, the dust in the grain will fly around, polluting the surrounding environment and requiring subsequent cleaning, which is not conducive to the work of workers. Therefore, a screening device for grain production is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-3 A screening device for grain production in this embodiment includes a shell 1, a filtering mechanism 2 is arranged on the front and rear sides of the shell 1, a vibration mechanism 3 is arranged on the outside of the shell 1, the filtering mechanism 2 includes two mounting shells 201, and the opposite sides of the two mounting shells 201 are respectively fixedly connected to the front and rear sides of the shell 1, and three dust suction pipes 202 are opened on the front and rear side walls of the inner cavity of the shell 1, one end of which penetrates and extends to the inside of the mounting shell 201, and the diameter of the dust suction pipe 202 gradually increases from one end to the other end of the mounting shell 201. The smaller diameter of the dust suction pipe 202 prevents grain from entering the mounting shell 201 through the dust suction pipe 202.

[0029] Among them, electric fans 203 are fixedly installed between the front and rear side walls of the inner cavity of the two mounting shells 201, and partition nets 204 are fixedly installed between the front and rear side walls of the inner cavity of the two mounting shells 201. The two partition nets 204 are respectively located on the top of the two electric fans 203, and the partition nets 204 prevent objects from falling into the electric fans 203.

[0030] Among them, two dust filter bags 205 are fixedly installed at the bottom of the outer shell 1, and two electric fans 203 allow air to enter the dust filter bag 205 through two mounting shells 201 respectively. A supporting frame is arranged inside the dust filter bag 205, and one end of the two dust filter bags 205 is fixedly connected to the top of the two mounting shells 201 respectively. The dust generated during grain screening enters the dust filter bag 205 from the dust suction pipe 202 and the mounting shell 201.

[0031] Specifically, two electric fans 203 are started so that air enters the dust filter bag 205 through the two mounting shells 201 respectively. At the same time, the air drives the air in the three dust suction pipes 202 to flow toward the dust filter bag 205, so that the dust generated during grain screening enters the dust filter bag 205 from the dust suction pipes 202 and the mounting shells 201, and the dust remains inside the dust filter bag 205. The air is discharged through the dust filter bag 205, and the partition net 204 prevents objects from falling into the electric fan 203 and causing damage to the electric fan 203, thereby reducing the pollution caused by dust to the surrounding environment and providing a good working environment for workers.

[0032] In this embodiment, the vibration mechanism 3 includes a vibration motor 301, the top of the vibration motor 301 is fixedly connected to the bottom of the shell 1, four vibration springs 302 are fixedly installed on the bottom of the shell 1, and a base frame 303 is fixedly installed on the bottom of the four vibration springs 302. The vibration motor 301 drives the shell 1 to vibrate through the four vibration springs 302.

[0033] Among them, a first screening net 304 is fixedly installed between the front and rear side walls of the inner cavity of the outer shell 1, and a second screening net 305 is fixedly installed between the front and rear side walls of the inner cavity of the outer shell 1. The grain is screened by the first screening net 304 and the second screening net 305. The first screening net 304 and the second screening net 305 are inclined when viewed from the front. The aperture of the first screening net 304 is larger than the aperture of the second screening net 305. The vibration of the first screening net 304 and the second screening net 305 causes the grain to move from left to right.

[0034] Among them, a feeding hopper 306 with one end penetrating and extending to the outside is fixedly installed inside the outer shell 1, and grain is added to the outer shell 1 through the feeding hopper 306. Three discharge pipes 307 are fixedly installed on the right side of the outer shell 1, and grains of different sizes are discharged through the three discharge pipes 307 respectively.

[0035] Specifically, when screening grains, grains are added to the outer shell 1 through the feeding hopper 306, and the vibration motor 301 is started to drive the outer shell 1 to vibrate through four vibration springs 302, so that the grains are screened by the first screening net 304 and the second screening net 305, and then the vibration of the first screening net 304 and the second screening net 305 causes the grains to move from left to right, and finally grains of different sizes are discharged through three discharge pipes 307 respectively, which can prevent the screening net from being blocked, ensure the screening effect of the grains, and improve the screening efficiency of the grains.

[0036] The working principle of the above embodiment is:

[0037] (1) When screening grains, the grains are added to the housing 1 through the hopper 306, and the vibration motor 301 is started to drive the housing 1 to vibrate through the four vibration springs 302, so that the grains are screened by the first screening net 304 and the second screening net 305. Then, the vibration of the first screening net 304 and the second screening net 305 causes the grains to move from left to right, and finally, grains of different sizes are discharged through the three discharge pipes 307 respectively.

[0038] (2) Start the two electric fans 203 so that the air enters the dust filter bag 205 through the two mounting shells 201 respectively. At the same time, the air drives the air in the three dust suction pipes 202 to flow toward the dust filter bag 205, so that the dust generated during grain screening enters the dust filter bag 205 from the dust suction pipes 202 and the mounting shells 201. The dust remains inside the dust filter bag 205, and the air is discharged through the dust filter bag 205. The partition net 204 prevents objects from falling into the electric fan 203 and causing damage to the electric fan 203.
