They are indispensable dry food in poor areas. my country is the world's largest producer, consumer and exporter of oats, and the scale of China's oat consumption market is gradually expanding, which puts higher and higher requirements on the production capacity of oats. In the prior art, after the oats in the field are harvested, the oat mixture obtained cannot meet the cleanliness requirements of grain storage or oat food processing, and it needs to be treated with impurities. When storing grain, the oat mixture is generally mechanically impurized, which has problems such as poor grain cleaning effect and high cost; before oat food processing, water washing is generally used for impurity removal, which causes problems such as waste of water resources and water pollution, which will cause grain loss and reduce impurity removal efficiency. Therefore, the existing oat impurity removal method is not only complicated, but also difficult to effectively separate oat grains and debris, and the impurity removal rate is low. Summary of the invention

[0003] In order to solve the problems that the existing oat impurity removal is relatively complicated, easily causes grain loss, and has a low impurity removal rate, the present invention provides an adhesive impurity removal device for cleaning oats.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: an adhesive impurity removal device for cleaning oats, comprising a shell, a feed hopper is installed on the top of the shell, a conveyor belt for receiving materials dropped from the bottom end of the feed hopper is arranged in the shell through two pulleys, a scraper plate is arranged above the conveyor belt, the scraper plate is located on one side of the feed hopper along the transmission direction of the conveyor belt, and the bottom edge of the scraper plate contacts the materials so that the materials form a uniform thickness layer distribution on the conveyor belt; a layer of cotton material is attached to the surface of the conveyor belt, a plurality of rubber rollers are arranged above the conveyor belt, the rubber rollers are located on one side of the scraper plate along the transmission direction of the conveyor belt, and a plurality of wool rollers are arranged below the conveyor belt. The axes of the brush roller, rubber roller and brush roller are parallel to the axis of the pulley. The outer peripheral surface of the rubber roller is pressed on the upper surface of the conveyor belt. The impurities in the material adhere to the upper surface of the conveyor belt through the extrusion of the rubber roller and the cooperation of the cotton material, so that the oat grains in the material slide down from one side of the conveyor belt along its conveying direction, and the impurities are transported to the lower surface of the conveyor belt. The impurities fall off from the lower surface of the conveyor belt by cleaning the lower surface of the conveyor belt when the brush roller rotates. A miscellaneous box and a grain box are provided on the bottom of the shell. The grain box is located below one side of the conveyor belt along its conveying direction. A motor for driving the pulley, rubber roller and brush roller to rotate synchronously is also provided on the bottom of the shell.

[0005] Preferably, the axial lengths of the rubber roller and the brush roller are not less than the width of the conveyor belt.

[0006] Preferably, one end of the conveyor belt is located directly below the feed hopper, and the end of the conveyor belt away from the feed hopper is higher than the end of the conveyor belt located directly below the feed hopper, so as to prevent the material from slipping on the conveyor belt along the conveying direction.

[0007] Preferably, the number of the rubber rollers and the number of the brush rollers are the same, and the plurality of rubber rollers and the plurality of brush rollers are respectively arranged at equal intervals along the conveying direction of the conveyor belt.

[0009] According to the above technical solution, the beneficial effects of the present invention are:

[0010] The adhesive impurity removing device for cleaning oats provided by the present invention feeds the oat mixture harvested by the oat combine harvester into the feed hopper, so that the oat mixture falls onto the upper surface of the conveyor belt. When the oat mixture passes through the scraper plate, it is spread into a uniform material layer by the bottom end of the scraper plate, and the material layer is squeezed in sequence by a plurality of rubber rollers. Since the thickness of the material layer is uniform, local accumulation of the material on the conveyor belt can be avoided, and the situation that some materials are subjected to strong squeezing force while some materials are subjected to weak squeezing force can be avoided, so as to ensure that all materials are squeezed uniformly. A layer of cotton material is attached to the surface of the conveyor belt, and the rubber roller squeezes and cooperates with the cotton material to form a uniform material layer. , so that the impurities such as shelled grains, weeds, oat husks in the material adhere to the upper surface of the conveyor belt, while the surface of the oat grains is relatively smooth and will not be adhered to the conveyor belt with cotton material. When the material is transported to the end of the conveyor belt, the oat grains will slide from the edge of the conveyor belt and fall into the grain collecting box, and the impurities will continue to adhere to the surface of the conveyor belt and be transported to the lower surface of the conveyor belt. There are multiple brush rollers under the conveyor belt. When the brush rollers rotate, they brush the lower surface of the conveyor belt, so that the impurities fall off from the lower surface of the conveyor belt and fall into the collecting box, thus realizing the impurity removal of the oat mixture and effectively separating the oat grains and impurities.

[0011] In summary, the present invention utilizes the characteristics that impurities in oats are more easily adhered to cotton materials while oat grains are not easily adhered to, and separates impurities from oat grains, which can effectively improve the cleanliness of oat grains, reduce seed loss, and improve the impurity removal rate, providing great convenience for subsequent oat storage, oat product processing, etc. The present invention can be realized by the cooperation of a rubber roller and a brush roller, has a simple structure, low manufacturing cost, has high practical value, and overcomes various problems in existing oat impurity removal.

[0016] A layer of cotton material is attached to the surface of the conveyor belt 4. A plurality of rubber rollers 6 are arranged above the conveyor belt 4. The rubber roller 6 is located on one side of the scraper plate 5 along the transmission direction of the conveyor belt 4. A plurality of brush rollers 7 are arranged below the conveyor belt 4. The axes of the rubber roller 6 and the brush roller 7 are parallel to the axis of the pulley 3. The axial lengths of the rubber roller 6 and the brush roller 7 are not less than the width of the conveyor belt 4. In this embodiment, the lengths of the rubber roller 6 and the brush roller 7 are equal to the width of the conveyor belt 4, so that both ends of the rubber roller 6 and the brush roller 7 are aligned with the edge of the conveyor belt 4.

[0017] There are three rubber rollers 6 and three brush rollers 7, and the plurality of rubber rollers 6 and the plurality of brush rollers 7 are respectively arranged at equal intervals along the conveying direction of the conveyor belt 4. The outer peripheral surface of the rubber roller 6 is pressed on the upper surface of the conveyor belt 4. The impurities in the material adhere to the upper surface of the conveyor belt 4 through the extrusion of the rubber roller 6 and the cooperation of the cotton material. The surface of the oat grains is relatively smooth and will not be adhered to the conveyor belt 4 with cotton material. Therefore, when the material is transported to the end of the conveyor belt 4, the oat grains in the material will slide from one side of the conveyor belt 4 along its conveying direction, and the impurities will be transported to the lower surface of the conveyor belt 4. The impurities can be removed from the lower surface of the conveyor belt 4 by cleaning the lower surface of the conveyor belt 4 when the brush roller 7 rotates.

[0018] Since a uniform material layer is formed under the action of the material scraper 5, local accumulation of materials on the conveyor belt 4 can be avoided, and the situation where some materials are subjected to strong extrusion pressure and some materials are subjected to weak extrusion pressure can be avoided, so as to ensure that all materials are uniformly extruded. In addition, in this embodiment, one end of the conveyor belt 4 is arranged directly below the feed hopper 2, and the end of the conveyor belt 4 away from the feed hopper 2 is higher than the end of the conveyor belt 4 directly below the feed hopper 2, so as to avoid the material from sliding down along the conveying direction on the conveyor belt 4, thereby extending the conveying time of the material on the conveyor belt 4, so that the rubber roller 6 can fully squeeze the material, and ensure that the impurities adhere to the upper surface of the conveyor belt 4.

[0019] The bottom surface of the housing 1 is provided with a sundry box 8 and a grain box 9, and the grain box 9 is located below the conveyor belt 4 on one side of its conveying direction. The bottom surface of the housing 1 is also provided with a motor 10 for driving the pulley 3, the rubber roller 6 and the brush roller 7 to rotate synchronously. The motor 10 is located below the conveyor belt 4 on one side of its conveying direction. The motor 10 drives the pulley 3 close to it to rotate through a section of V-shaped belt 11. The wheel axle of the pulley 3 is connected to the wheel axle of the rubber roller 6 and the brush roller 7 close to the motor 10 through two sections of V-shaped belts 11. The wheel axles of the two adjacent rubber rollers 6 and the wheel axles of the two brush rollers 7 are connected to the conveyor belt 4 on one side of its conveying direction. Each shaft is connected with a respective V-belt 11, so that the motor 10 can drive the conveyor belt 4, multiple rubber rollers 6 and multiple brush rollers 7 to operate synchronously, and the material will be effectively separated into impurities and oat grains, and automatically classified and collected in the impurity collection box 8 and the grain collection box 9, which effectively improves the cleanliness of the oat grains, reduces the loss of grains, and increases the impurity removal rate, providing great convenience for subsequent oat storage, oat product processing, etc. The present embodiment has a simple structure and low manufacturing cost, and overcomes the various problems of existing oat impurity removal, such as being relatively complicated, easily causing grain loss, and having a low impurity removal rate.
