Description

Technical Field

[0001] This utility model belongs to the technical field of grain conveyors, specifically relating to a grain conveyor with a cleaning function. Background Technology

[0002] Grains refer to the general term for various plant seeds used in cooking. Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat and starch. In the process of grain production and processing, grain conveyors are usually used to transfer and transport grains.

[0003] According to the patent announcement number CN215046502U, a grain conveyor with grain impurity removal function is known prior art. Although this patent has the advantage of being able to screen and clean large particles of impurities in grain, the technical solution of this patent still has the following defects in actual use: When using a screen for impurity removal, small particles such as dust will pass through the mesh of the screen and flow downwards, falling onto the polyester conveyor belt along the conveyor pipe. This will cause small particles of dust and other impurities to fly during the grain conveying process, thus affecting the working environment around the grain conveyor. Therefore, we propose a grain conveyor with impurity removal function. Utility Model Content

[0004] The purpose of this invention is to provide a grain conveyor with a cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain conveyor with impurity removal function, comprising a base, an mounting plate fixedly connected to one side of the top of the base, a grain impurity removal box fixedly connected to one side of the mounting plate, a screen fixedly fitted inside the grain impurity removal box, a vibrating motor fixedly connected to the bottom of the screen, a dust suction pipe fixedly connected to one side of the grain impurity removal box, and a filter cover fixedly connected to the inner side of the grain impurity removal box, a dust suction pump fixedly installed outside the dust suction pipe, and a grain conveying mechanism provided on the top of the base.

[0006] In a preferred embodiment, the bottom of the base is fixedly equipped with rollers, the top of the grain impurity removal box is fixedly equipped with a top cover, the top of the top cover is fixedly equipped with a feeding funnel, the bottom of the grain impurity removal box is fixedly connected with a discharge pipe, and a discharge valve is fixedly installed on the outside of the discharge pipe.

[0007] In a preferred embodiment, the filter cover is fixedly sleeved on the outside of one end of the suction pipe, and the aperture value of the filter holes on the surface of the filter cover is smaller than the aperture value of the mesh on the surface of the screen.

[0008] In a preferred embodiment, the grain conveying mechanism includes a support plate, which is fixedly connected to the top of the base. A drive shaft is movably sleeved on the front of the support plate. A drive motor is fixedly connected to one end of the drive shaft, and a drive wheel is fixedly sleeved on the outside of the drive shaft. A conveyor belt is movably sleeved on the outside of the drive wheel.

[0009] In a preferred embodiment, a baffle assembly is provided on the side of the grain conveying mechanism, and a guide plate is provided at the bottom of the top of the grain conveying mechanism.

[0010] In a preferred embodiment, the material blocking assembly includes a horizontal plate, which is fixedly connected to the inner side of the support plate.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figure 2 and Figure 3 This utility model provides a grain conveyor with impurity removal function, including a base 1, with rollers fixedly installed at the bottom of the base 1, an installation plate 2 fixedly connected to one side of the top of the base 1, a grain impurity removal box 3 fixedly connected to one side of the installation plate 2, a top cover 4 fixedly installed at the top of the grain impurity removal box 3, a feeding funnel 5 fixedly installed at the top of the top cover 4, a discharge pipe 6 fixedly connected to the bottom of the grain impurity removal box 3, a discharge valve fixedly installed on the outside of the discharge pipe 6, a screen 7 fixedly sleeved inside the grain impurity removal box 3, and a vibration motor 8 fixedly connected to the bottom of the screen 7.

[0021] In this embodiment, when the grain to be transported is added into the grain impurity removal box 3 from the feed hopper 5, the vibration motor 8 is turned on to run and drive the screen 7 to vibrate. At this time, the grain piled on top of the screen 7 will be screened by the vibration force, which makes it easier to separate large particles of impurities from the grain. The grain and small particles of impurities (such as dust) will flow down through the mesh of the screen 7 and accumulate at the bottom of the inner cavity of the grain impurity removal box 3.

[0022] Please see Figure 1 and Figure 2 A dust suction pipe 9 is fixedly connected to one side of the grain impurity removal box 3, and a filter cover 10 is fixedly connected to the inside of the grain impurity removal box 3. A dust suction pump 11 is fixedly installed on the outside of the dust suction pipe 9. The filter cover 10 is fixedly sleeved on the outside of one end of the dust suction pipe 9, and the aperture value of the filter holes on the surface of the filter cover 10 is smaller than the aperture value of the mesh on the surface of the screen 7, and the aperture value of the filter holes on the surface of the filter cover 10 is smaller than the particle size of the grain.

[0023] In this embodiment, when grain and small particulate impurities (such as dust) flow downwards, the dust pump 11 is activated, which creates a negative pressure inside the dust suction pipe 9. At this time, the small particulate impurities (such as dust) in the grain will pass through the filter cover 10 due to the suction force and enter from one end of the dust suction pipe 9. They will be discharged and collected outwards along the dust suction pipe 9, which facilitates the absorption and treatment of small particulate impurities (such as dust) mixed in the grain. This avoids the problem of a large amount of dust being generated during the transport of grain, thereby improving the working environment around the grain conveyor.

[0024] Please see Figure 1 and Figure 2 The top of the base 1 is provided with a grain conveying mechanism 12. The grain conveying mechanism 12 includes a support plate 121. The support plate 121 is fixedly connected to the top of the base 1. A drive shaft 122 is movably sleeved on the front of the support plate 121. A drive motor 123 is fixedly connected to one end of the drive shaft 122. A drive wheel 124 is fixedly sleeved on the outside of the drive shaft 122. A conveyor belt 125 is movably sleeved on the outside of the drive wheel 124.

[0025] In this embodiment, when the discharge pipe 6 is pulled down to cause it to stretch and deform, the bottom end of the discharge pipe 6 is brought close to the top of the conveyor belt 125. Then, the drive motor 123 is turned on, causing the transmission shaft 122 to rotate. The transmission shaft 122 will drive the transmission wheel 124 to rotate, and the transmission wheel 124 will drive the conveyor belt 125 to move. At this time, the discharge valve is opened, so that the grain accumulated at the bottom of the grain impurity removal box 3 can fall down the discharge pipe 6 to the top of the conveyor belt 125, so that the grain on the conveyor belt 125 can move together with the conveyor belt 125, thereby facilitating the transport of grain.

[0026] Please see Figure 1 and Figure 2 A baffle assembly 13 is provided on the side of the grain conveying mechanism 12, and a guide plate 14 is provided at the bottom of the top of the grain conveying mechanism 12. The baffle assembly 13 includes a horizontal plate 131, which is fixedly connected to the inner side of the support plate 121. A fixing plate 132 is fixedly connected to the top of the horizontal plate 131, and a baffle 133 is fixedly connected to the back of the top of the fixing plate 132. The baffle 133 is located on the side of the conveyor belt 125, and the guide plate 14 is located at the bottom of the top of the conveyor belt 125.

[0027] In this embodiment, when the grain on the conveyor belt 125 is being transported, the baffle 133 can block the transported grain on both sides of the conveyor belt 125, preventing the grain from falling off the conveyor belt 125, thus facilitating the transport of the grain.

[0028] The working principle and usage process of this utility model are as follows: First, the grain to be conveyed is added into the grain impurity removal box 3 from the feed hopper 5. At the same time, the vibration motor 8 is turned on to make it run and drive the screen 7 to vibrate. At this time, the grain piled on the top of the screen 7 will be screened due to the vibration force, which makes it easier to separate large particles of impurities from the grain. The grain and small particles of impurities (such as dust) will flow downward through the mesh of the screen 7.

[0029] Next, the dust pump 11 is started, which creates a negative pressure inside the dust suction pipe 9. At this time, small particles of impurities (such as dust) in the grain will pass through the filter cover 10 due to the suction and enter from one end of the dust suction pipe 9. They will be discharged and collected outward along the dust suction pipe 9, which facilitates the suction and treatment of small particles of impurities (such as dust) mixed in the grain. This avoids the problem of a large amount of dust being generated during the transport of grain, thereby improving the working environment around the grain conveyor.

[0030] Finally, pull down the discharge pipe 6 to stretch and deform it, causing the bottom of the discharge pipe 6 to approach the top of the conveyor belt 125. Then turn on the drive motor 123 to make the drive shaft 122 rotate. The drive shaft 122 will drive the drive wheel 124 to rotate, and the drive wheel 124 will drive the conveyor belt 125 to move. At this time, open the discharge valve so that the grain accumulated at the bottom of the grain impurity removal box 3 can fall down the discharge pipe 6 to the top of the conveyor belt 125, so that the grain on the conveyor belt 125 can move together with the conveyor belt 125, thereby facilitating the transport of grain.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
