Description

Technical Field

[0001] The utility model belongs to the technical field of feeding mechanisms, and in particular relates to a feeding mechanism and a silo comprising the feeding mechanism. Background Art

[0002] The existing multi-row screw feeder will produce uneven discharge when discharging soybean meal from the silo. The material discharge speed is fast on the side close to the auger shaft motor, and almost no material is discharged on the side close to the feeder outlet. This discharge characteristic makes the material surface in the entire circular steel silo tilted, and the material load in the silo is eccentric, which has an adverse effect on the steel silo side plate, cone bucket and discharge port flange, deviating from the scope of application of the "Grain Steel Silo Design Code" GB50322-2011. For details, see the general excerpt.

[0003] The following contents are recorded in the "Grain Steel Silo Design Code" GB50322-2011: 1.0.2 This article explains the scope of application of this code, which is applicable to the design of grain steel silos with circular plane shape and central loading and unloading, including the design of grain steel silo architecture, structural design, grain in and out process, grain storage process, electrical and grain condition measurement and control and other related professional designs. Grain steel silos are thin-walled structures with large diameter-thickness ratio and poor stability. In engineering practice, there have been accidents in which eccentric unloading of grain has caused eccentric loads to be generated during the grain flow process, resulting in instability and collapse of the silo. There is currently no mature calculation method for the eccentric load of silos caused by eccentric unloading. When the process requires the setting of multiple inlet and outlet ports, special attention should be paid to symmetrical and equal flow arrangements, and measures should be taken to prevent some inlets from being unblocked and some from being blocked, resulting in eccentric inlet and outlet, causing eccentric loading of the silo wall.

[0004] In addition, the discharging characteristics of the existing multi-row screw feeders make it impossible for materials such as soybean meal, which are prone to arching, to meet the first-in-first-out principle of silo materials. Assuming that only half of the soybean meal in the silo is used and then refilled, the priority for the next discharging will still be the part that was emptied after the previous discharging and was filled with the second loading. The priority is always the material in the cone bucket above the auger motor side. If the silo is not emptied for a long time, the soybean meal on the auger outlet side will cause arching and blockage in the silo, which will cause great harm and processing costs. Utility Model Content

[0005] The first purpose of the utility model is to provide a floating curved surface sealing structure, which solves the technical problems that the existing multi-row screw feeder transports materials from the motor side to the discharge port side, the one-way output leads to eccentricity, uneven discharge, and eccentric loading of the warehouse wall.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions, the feeding mechanism is characterized in that it includes:

[0007] The arch-breaking section has an arch-breaking section discharge port arranged in the middle of the bottom plate of the arch-breaking section; a plurality of feeding components are arranged side by side in the arch-breaking section, and the feeding components are used to transport materials from both sides of the arch-breaking section to the middle to the arch-breaking section discharge port;

[0008] The bin discharge section is arranged below the arch-breaking section, and is used for receiving the material from the discharge port of the arch-breaking section and conveying the material to the discharge port of the bin discharge section.

[0009] The utility model changes the arrangement of the spiral shaft of the feeder to design a double-layer feeding system with multiple rows of feeding components arranged on the upper layer, and the feeding components are designed to discharge materials by spiral conveying from both sides to the middle, so as to ensure symmetrical discharge in the bin and avoid the risk of eccentricity. A bin discharge section is arranged on the lower layer to convey the materials conveyed from the upper bin to the bin discharge scraper.

[0010] The utility model changes the material conveying direction and conveys materials from both sides to the middle by changing the arrangement form of the material conveying components of the feeder, thereby achieving the purpose of symmetrical material discharge in the bin.

[0011] In order to solve the technical problem of how to implement the feeding component, the utility model adopts the following technical solution: the feeding component is an auger structure, including a first auger shaft, and a first spiral blade and a second spiral blade arranged at both ends of the first auger shaft, and the first spiral blade and the second spiral blade have opposite rotation directions; the first spiral blade and the second spiral blade are located on both sides of the discharge port of the broken arch section.

[0012] In order to solve the technical problem of eccentric loading of the silo wall, the utility model adopts the following technical solution: both the first spiral blade and the second spiral blade are variable pitch structures to ensure that the broken arch section discharges material evenly to the middle.

[0013] In order to solve the technical problem of how to realize the warehouse discharge section, the utility model adopts the following technical solution, and the warehouse discharge section includes:

[0014] A bin outlet shell, on which a bin outlet feed port and a bin outlet discharge port are arranged, and the bin outlet feed port is connected to the arch-breaking section discharge port;

[0015] The bin-out auger is arranged in the bin-out shell, and is vertically arranged between the bin-out auger and the feeding assembly.

[0016] In order to solve the technical problem of how to realize the warehouse discharge auger, the utility model adopts the following technical solution. The warehouse discharge auger includes a second auger shaft and a third spiral blade arranged on the second auger shaft.

[0017] In order to further solve the technical problem of eccentric loading of the silo wall, the utility model adopts the following technical solution: the third spiral blade is a variable pitch structure. The lower silo discharge auger also adopts a rotor structure with a variable pitch design, which discharges the material evenly, ensuring that the upper material is discharged in a relatively uniform state, effectively avoiding the eccentricity of the material in the silo.

[0018] The utility model is further improved in that the warehouse discharge auger is a single auger structure. A single-axis warehouse discharge auger is arranged at the lower layer of the feeding mechanism to transport the materials transported down from the upper warehouse to the warehouse discharge scraper.

[0019] In order to solve the technical problem of how to drive the feeding assembly, the utility model adopts the following technical solution, and the arch breaking section includes:

[0020] A housing, on which the feeding assembly is arranged;

The transmission mechanism adopts a shaft-mounted transmission form, which not only facilitates the on-site installation of the equipment, but also reduces the subsequent equipment maintenance work.

[0035] Example 1

[0038] The housing 120 includes a side plate and a bottom plate. A broken arch section discharge port 121 is arranged in the middle of the bottom plate. A bearing is installed on the feed housing 120 to support the feed assembly 110.

[0039] Several feeding assemblies 110 are installed side by side in the housing 120, and the feeding assemblies 110 are used to transport materials from both sides of the broken arch section to the middle to the broken arch section discharge port 121. The number of feeding assemblies 110 is preferably an even number, such as 4, 6, or 8.

[0040] In one embodiment, the feeding assembly 110 is an auger structure, including a first auger shaft 111, and both ends of the first auger shaft 11 are supported on bearings on the feed shell 120. The first spiral blade 112 and the second spiral blade 113 are respectively installed at both ends of the first auger shaft 11, and the rotation directions of the first spiral blade 112 and the second spiral blade 113 are opposite; the first spiral blade 112 and the second spiral blade 113 are located on both sides of the arch-breaking section discharge port 120. The feeding assembly 110 (spiral shaft) adopts a design of spiral conveying and discharging from both sides to the middle to ensure symmetrical discharging in the bin and avoid the risk of eccentricity. Preferably, the first spiral blade 112 and the second spiral blade 113 are symmetrically arranged on both sides of the arch-breaking section discharge port 120.

[0041] In one embodiment, the first spiral blade 112 is a variable pitch structure. The second spiral blade 113 is a variable pitch structure. The upper multi-row auger adopts a variable pitch design with symmetry at both ends to discharge materials evenly to the middle.

[0042] The feed assembly transmission mechanism 130 is installed on the feed housing 120 to drive the feed assembly. Specifically, the feed assembly transmission mechanism 130 adopts a shaft-mounted transmission structure, which not only facilitates the on-site installation of the equipment, but also reduces the subsequent equipment maintenance work. The feed assembly transmission mechanism 130 is installed on both sides of the feed housing 120 to prevent the feed housing from being eccentrically loaded due to the installation of the feed assembly transmission mechanism 130 on one side.

[0043] The bin discharge section 200 is arranged below the arch breaking section 100, and is used for receiving the material from the discharge port of the arch breaking section and conveying the material to the discharge port of the bin discharge section.
