Description

Technical Field

[0001] The utility model relates to the technical field of grain silo unloading equipment, in particular to a primary cleaning device used in conjunction with a grain silo unloading port. Background Art

[0002] In modern agricultural production and grain processing industries, granaries are important facilities for storing and protecting grain from external damage, and they play a vital role in the grain production supply chain. However, the problems existing in the grain unloading process have become a bottleneck restricting grain quality and storage efficiency. In particular, there is no effective primary cleaning equipment at the grain unloading port, which makes the dust problem in the grain unloading process particularly prominent.

[0003] In the traditional grain unloading process, due to the lack of effective cleaning and separation equipment, the grain will be taken out with dust when it is unloaded, which not only increases the difficulty and cost of subsequent grain processing, but also has a significant impact on the air quality of the surrounding environment. The emission of dust and other tiny particles not only poses a potential threat to the health of operators, but may also violate environmental regulations, resulting in economic penalties and reputational losses for the company.

[0004] In addition, the presence of dust in grain materials seriously affects the quality of grain and increases the difficulty of grain cleaning, transportation and packaging. During grain processing, excessive dust will lead to increased mechanical wear and tear, and a significant increase in cleaning and maintenance workload, which in turn affects production efficiency and increases operating costs. Especially for those processing links that have strict requirements on grain cleanliness, such as flour milling and food processing, the dust problem is even more related to the quality of the final product and even affects the market competitiveness of the product.

[0005] Currently, there is a general lack of dedicated cleaning facilities that can be installed directly at the grain silo discharge port. Many grain silos rely on manual cleaning or simple screening equipment, which are not only inefficient but also fail to meet the high standards of grain cleanliness required by the grain handling industry.

The connection between the oblique passage and the vertical passage is fixedly connected to an assembly seat arranged on the outside of the grain unloading pipeline. The port of the vertical passage is fixedly connected to a support frame, and the vertical passage is connected to the grain unloading passage. The mounting shaft is rotatably installed on the assembly seat and the support frame, and the spiral conveying blades are arranged in the vertical passage.

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-4 The primary cleaning equipment for the grain unloading port of the grain silo includes a grain unloading pipe 11, a dust exhaust pipe 12, and a dust cleaning pipe 13. The dust cleaning pipe 13 includes a grain unloading passage 131 arranged obliquely downward and a dust exhaust passage 132 connected to the grain unloading passage 131 and maintained obliquely upward. The top port of the grain unloading passage 131 is fixedly connected to the bottom port of the grain unloading pipe 11, and the top port of the grain unloading pipe 11 is fixedly connected to the grain unloading port of the grain silo. One end of the dust exhaust pipe 12 is fixedly connected to the dust exhaust passage 132, and the other end of the dust exhaust pipe 12 is set to a closing section 121, and the closing section 121 is matched with an exhaust fan 122.

[0026] It also includes a material guiding assembly installed in the grain unloading pipe 11 and a material beating assembly installed in the dust cleaning pipe 13. The material guiding assembly includes a mounting shaft 21 rotatably installed in the grain unloading pipe 11 and a spiral conveying blade 22 fixedly connected to the mounting shaft 21 and kept in contact with the inner wall of the grain unloading pipe 11; the material beating assembly is arranged at the connection between the grain unloading passage 131 and the dust exhaust passage 132.

[0027] It also includes a driving assembly, which is dynamically connected to the mounting shaft 21 and the punching assembly.

[0028] The grain unloading pipeline 11 is connected to the grain unloading port of the grain silo. When the grain is unloaded from the grain silo, the grain is output from the grain unloading port and transported to the cleaning pipeline 13 along the grain unloading pipeline 11. The material guide component installed in the grain unloading pipeline 11 can drive the grain therein to be smoothly transported to the cleaning pipeline 13. At the same time, the rotation speed of the mounting shaft 21 and the spiral conveying blades 22 thereon can be adjusted to control the flow rate of the grain transmitted to the cleaning pipeline 13.

[0029] After the grain enters the dust removal duct 13, it will be further discharged along the grain unloading passage 131 arranged obliquely downward. When it flows to the connection between the grain unloading passage 131 and the dust exhaust passage 132, the dust carried by the grain can be blown up by the material beating assembly. Due to the action of the exhaust fan 122 installed on the closing section 121 of the dust exhaust duct 12, the dust in the dust exhaust duct 12, the dust exhaust passage 132, and the grain unloading passage 131 can be sucked away and finally discharged to the outside through the exhaust fan 122, and the exhaust port of the exhaust fan 122 can be connected to the dust removal equipment, which can prevent the dust from being directly discharged into the surrounding environment, and can effectively improve the ambient air quality during the grain unloading process in the granary.

[0030] Since the dust exhaust passage 132 is arranged upwardly and the negative pressure force generated by the exhaust fan 122 is smaller than the dead weight of the particles in the two chambers, it can effectively prevent the grain particles from flowing along the dust exhaust passage 132 and the dust exhaust pipe 12 into the exhaust fan 122 .

[0031] It should also be noted that the diameter of the dust exhaust duct 12 is relatively large, which can maximize the cleaning effect of dust carried in the grain, so that the dust can be effectively discharged along the dust exhaust duct 12, and the closing section 121 design of the port of the dust exhaust duct 12 can ensure its effective connection with the air inlet of the exhaust fan 122.

[0032] After the grain has been processed as described above in the grain unloading passage 131, it is finally discharged from the bottom port of the grain unloading passage 131, thereby completing the preliminary dust cleaning of the grain unloaded from the granary and cleaning the dust as completely as possible to reduce the production cost of subsequent grain processing and handling and save the subsequent grain processing time.

[0033] It should also be noted that connecting flanges 14 are installed at both end ports of the grain unloading pipe 11, both end ports of the dust exhaust pipe 12, and the top ports of the grain unloading passage 131 and the top ports of the dust exhaust passage 132, which can ensure stable connection of each pipe and ensure its stable connection with the exhaust fan 122 and the grain unloading port.

[0034] In order to ensure that the grain unloading pipeline 11 can be stably connected to the grain unloading port of the granary and that the material guiding component can be stably assembled therein, the following technical solution is provided.

[0035] The grain unloading pipeline 11 includes an oblique passage and a vertical passage which are interconnected. The end of the oblique passage is connected to the grain unloading port of the granary. An assembly seat 113 arranged on the outside of the grain unloading pipeline 11 is fixedly connected to the connection between the oblique passage and the vertical passage. A support frame 114 is fixedly connected to the end of the vertical passage, and the vertical passage is connected to the grain unloading passage 131. The mounting shaft 21 is rotatably mounted on the assembly seat 113 and the support frame 114, and the spiral conveying blade 22 is arranged in the vertical passage.

[0036] The vertical passage is arranged along the vertical direction, which can ensure that the installation shaft 21 and the spiral conveying blade 22 are stably installed therein and perform their functions. Correspondingly, the setting of the oblique passage can ensure the connectivity between the vertical passage and the grain unloading port of the granary.

[0037] The arrangement of the assembly seat 113 and the support frame 114 can ensure that the mounting shaft 21 is stably installed in the vertical passage, and the support frame 114 is arranged to be hollow to ensure that the grain particles fall normally from here and enter the dust exhaust passage 132 of the cleaning pipe 13.

[0038] When the installation shaft 21 drives the spiral conveying blade 22 to operate, the grain particles in the vertical passage can be driven to flow toward the cleaning pipe 13. The flow rate of the grain particles here can be controlled by adjusting the rotation speed of the installation shaft 21 and the spiral conveying blade 22.

[0039] In order to ensure that the drive assembly is stably installed and effectively drive the installation shaft 21 to operate stably, the following technical solution is provided.

[0040] The driving assembly includes a driving motor 41, a driving bevel gear 42, and a transmission bevel gear 43. The driving motor 41 is fixedly mounted on the assembly seat 113, the driving bevel gear 42 is fixedly connected to the output shaft of the driving motor 41, and the transmission bevel gear 43 is fixedly connected to the top of the mounting shaft 21 and keeps meshing with the transmission bevel gear 43.

[0041] The setting of the assembly seat 113 can ensure that the driving motor 41 is stably installed thereon. When the driving motor 41 is running, it can drive the driving bevel gear 42 to operate, and then drive the transmission bevel gear 43 and the mounting shaft 21 and the spiral conveying blade 22 to operate stably, so as to drive the stable transmission of grain in the grain unloading pipeline 11. By adjusting the output power of the driving motor 41, the grain transmission speed in the grain unloading pipeline 11 can be regulated.

[0042] In order to ensure that the material beating assembly can be stably assembled at the connection between the grain unloading passage 131 and the dust exhaust passage 132 in the dust cleaning pipe 13, and effectively act on the grain particles passing through, the following technical solution is provided.

[0043] The material beating assembly includes a connecting shaft 31 rotatably installed in the cleaning pipe 13 and an arc plate 32 evenly fixed on the connecting shaft 31. The arc plate 32 is arranged in the cleaning pipe 13 and does not interfere with the movement of the cleaning pipe 13. The connecting shaft 31 is powered by a driving motor 41.

[0044] While the driving motor 41 drives the material guiding assembly to operate, it can also drive the connecting shaft 31 and the arc plate 32 fixed thereon to operate stably. The operating arc plate 32 can lift up or knock down the passing grain particles, thereby blowing up the dust carried by it, and use the negative pressure generated by the exhaust fan 122 to draw the dust into the dust exhaust duct 12 and finally discharge it externally.

[0045] Due to the structural characteristics of the arc plate 32 , a gap is provided between the middle part and the connecting shaft 31 , which can ensure that grain particles pass through this part and the periphery of the arc plate 32 , and ensure that the grain can be discharged from the end of the grain unloading passage 131 .

[0046] In order to ensure that the driving motor 41 can effectively link with the connecting shaft 31 and ensure that the driving motor 41 can drive the connecting shaft 31 to operate stably, the following technical solution is provided.

[0047] The driving assembly further includes a pulley 44 , and the connecting shaft 31 and the driving bevel gear 42 are both fixedly connected with pulleys 44 , and the two sets of pulleys 44 are connected in power via a belt ring 45 .

[0048] When the driving motor 41 drives the driving bevel gear 42 to rotate, the power can be transmitted to the pulley 44 fixed to the driving bevel gear 42, and then the power is transmitted to another set of pulleys 44 through the belt ring 45, thereby driving the connecting shaft 31 and the arc plate 32 to operate stably.

[0049] When the output power of the driving motor 41 is reduced to control the grain flow speed, the rotation speed of the connecting shaft 31 and the arc plate 32 is also reduced to match the speed of the grain passing through the material beating assembly.

[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
