Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a feeding bin arch-breaking conveying device and method. Background Technology

[0002] Agricultural machinery and conveying equipment are often equipped with feeding hoppers, such as those in automatic fertilization devices and automatic feeding devices, which contain feeding hoppers for materials such as organic fertilizer, feed, and biomass pellets. Due to limitations in the supply capacity, the bottom outlet of the feeding hopper is usually small. When conveying materials such as organic fertilizer, the material inside the hopper is prone to accumulating and arching during the conveying process, which prevents the material from continuously falling into the bottom outlet and hinders continuous automatic discharge, thus affecting its use.

[0003] To address the problem of material accumulation and arching in the feed hoppers of organic fertilizers and other materials, Chinese patent application CN107754665A discloses a mixing device for fertilizer applicators. This device features a rotating shaft in the middle of the hopper, a drive unit at the upper end of the shaft, a mixing assembly at the upper part of the shaft, and an anti-clogging assembly at the lower part. The mixing assembly includes multiple mixing rods arranged radially along the rotating shaft, multiple mixing elements mounted on the mixing rods near the rotating shaft, and pressing plates mounted on the mixing rods away from the rotating shaft, with the pressing plates inclined downwards. The anti-clogging assembly includes spiral blades wound around the rotating shaft and scrapers located outside the spiral blades and close to the side wall of the hopper, with the spiral blades extending to the hopper's outlet. This device improves the uniformity of mixing and partially prevents material accumulation and clogging in the hopper. However, such mixing devices still only rotate regularly during the mixing process and cannot provide axial impact force. During the mixing process, the frictional resistance between the spiral blades, the material and the side wall of the hopper is large, which makes the drive device prone to jamming. Moreover, the material above the mixing components does not easily fall down after it accumulates and arches, so the function of breaking the arch and preventing blockage is relatively average. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a material feeding silo arch-breaking conveying device and method, which can provide irregular vertical impact to disperse materials during conveying and mixing, effectively solving the problem of material accumulation and arching in the feeding silo, effectively preventing silo blockage, and ensuring stable and uniform automatic discharge.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material feeding hopper anti-bridging conveying device includes a hopper body, a horizontal rotating feeding component, a vertical anti-bridging component, and a discharge rate adjustment component. The horizontal rotating feeding component is located above the discharge port at the bottom of the hopper body and includes a horizontal rotating shaft, a feeding wheel assembly, and an eccentric wheel. The eccentric wheel is positioned on the horizontal rotating shaft between the feeding wheel assemblies. The feeding wheel assembly conveys the material in the hopper body towards the discharge port through horizontal rotation. The vertical anti-bridging component includes a vertical push rod, an anti-bridging spring assembly, and a rebound mechanism. The lower end of the vertical push rod contacts the rotating surface of the eccentric wheel. The anti-bridging spring assembly is wound around the vertical push rod. The rebound mechanism is located on the upper part of the vertical push rod to press it against the eccentric wheel. The eccentric wheel drives the vertical push rod to reciprocate up and down and rotate. The vertical push rod drives the anti-bridging spring assembly to generate irregular vibration and impact trajectories in the vertical direction to disperse the material. The discharge volume adjustment component is located in the hopper above the horizontal rotating feeding component. The discharge volume adjustment component is provided with a discharge gate for controlling the discharge volume. The material dispersed by the vertical anti-bridging component falls into the horizontal rotating feeding component through the discharge gate.

[0007] Furthermore, the discharge gate includes one or more, the discharge gate is disposed in the hopper above the horizontal rotating feeding component, the two ends of the door shaft of each discharge gate are respectively hinged to the hopper wall of the hopper, an adjusting link is provided between the door shafts of the discharge gate, and at least one door shaft of the discharge gate is connected to an opening adjustment mechanism, the opening adjustment mechanism drives the discharge gate to open and close through the adjusting link.

[0008] Furthermore, the opening adjustment mechanism includes a manual rotation mechanism or an automatic rotation mechanism.

[0009] Furthermore, the rebound mechanism includes a spring seat, a compression spring, and an adjusting pressure plate. The spring seat is fixed to the bottom surface of the mounting crossbar, the mounting crossbar is fixed to the upper part of the chamber, the compression spring is disposed in the spring seat cavity, the adjusting pressure plate is inserted through the vertical push rod, and the vertical push rod is provided with an adjusting nut for pressing the adjusting pressure plate and the compression spring. The upper end of the vertical push rod passes through the holes on the spring seat and the mounting crossbar.

[0010] Furthermore, the arch-breaking spring assembly is provided with a spiral-shaped impact spring, which is inserted into a fixing hole in the rebound plate, and the rebound plate is fixed on the vertical push rod.

[0011] Furthermore, the striking spring is wrapped with elastic steel wire or rope, and the rebound plate is a torsional elastic plate.

[0012] Furthermore, the horizontal rotating shaft is connected to the drive device, and each set of the feeding wheel group is provided with two or more feeding blades.

[0013] Furthermore, the eccentric wheel has a guide groove on its contour rotation surface, and the lower end of the vertical push rod has a contact end that mates with the guide groove.

[0014] Furthermore, the hopper is provided with an auxiliary guide sleeve rod, which is located above the horizontal rotating feeding component. The lower end of the vertical push rod passes through the guide sleeve on the auxiliary guide sleeve rod. The discharge gate is located below the auxiliary guide sleeve rod.

[0015] The method for breaking up arches in a feeding silo conveying device, as described above, includes the following steps:

[0016] S1. Adjust the preload of the spring mechanism so that the lower end of the vertical push rod is in close contact with the eccentric wheel profile rotation surface;

[0017] S2. Adjust the opening of the discharge gate to control the discharge amount of material;

[0018] S3. The horizontal rotating shaft and the feeding wheel assembly are driven by an external power source to rotate, conveying material to the discharge port. At the same time, the eccentric wheel pushes the vertical push rod to move up and down reciprocally. Under the action of the vertical push rod and the rebound mechanism, the anti-bridging elastic bar assembly follows the up and down reciprocating motion. During the up and down reciprocating motion, the anti-bridging elastic bar assembly has an irregular motion trajectory due to its elasticity. The irregular up and down vibration of the anti-bridging elastic bar assembly is used to break up the material in the bin. The broken material falls into the horizontal rotating feeding component through the opening of the discharge gate and is sent out by the feeding wheel assembly.

[0019] The present invention has the following beneficial effects:

[0020] 1. This invention simultaneously sets up a horizontal rotating feeding component and a vertical arch-breaking component in the feeding hopper. When the horizontal rotating feeding component conveys the mixed material, the vertical arch-breaking component provides irregular vertical impact. The irregular up-and-down vibration and rotational impact of the vertical arch-breaking component can effectively disperse the material in the hopper. The dispersed material falls through the discharge gate into the horizontal rotating feeding component for continuous conveying. This can effectively solve the problem of material accumulation and arching in the feeding hopper, effectively avoid clogging of the feeding hopper, and ensure stable and uniform automatic discharge.

[0021] 2. The vertical arch-breaking component of this invention is equipped with a vertical push rod, an arch-breaking elastic bar assembly, and a rebound mechanism. The vertical push rod provides the power for vertical vibration through the eccentric wheel in the horizontally rotating feeding component. Utilizing the elastic characteristics of the spiral arch-breaking elastic bar assembly, the arch-breaking elastic bar assembly can generate irregular vibration impact in the vertical direction under the action of the vertical push rod and the rebound mechanism. Furthermore, it will continuously rotate during the vertical vibration, which can effectively impact and disperse the material in the bin, preventing the material in the feeding bin from arching and blocking.

[0022] 3. In addition, the present invention also includes a discharge volume adjustment component, which includes a discharge gate for easy adjustment of the opening. The discharge gate is equipped with an adjustment linkage for easy opening and closing. The opening size (opening degree) of the discharge gate can be adjusted by rotating the angle of the discharge gate, which can better control the discharge volume. Furthermore, the vertical push rod moves up and down in the opening of the discharge gate, which also has the function of vibrating and loosening the material, resulting in a better anti-clogging effect.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0030] See Figure 1-4As shown, a material feeding hopper anti-bridging conveying device includes a hopper body 1, a horizontal rotating feeding component 2, a vertical anti-bridging component 3, and a discharge rate adjustment component 4. The horizontal rotating feeding component 2 is located above the discharge port at the bottom of the hopper body 1. The horizontal rotating feeding component 2 includes a horizontal rotating shaft 21, a feeding wheel assembly 22, and an eccentric wheel 23. The eccentric wheel 23 is located on the horizontal rotating shaft 21 between the feeding wheel assemblies 22. The feeding wheel assembly 22 conveys the material in the hopper body 1 towards the discharge port through horizontal rotation. The vertical anti-bridging component 3 includes a vertical push rod 31, an anti-bridging spring assembly 32, and a rebound mechanism 33. The lower end of the vertical push rod 31 is aligned with the contour rotation surface of the eccentric wheel 23. In contact, the arch-breaking elastic bar assembly 32 is wrapped around the vertical push rod 31, and the rebound mechanism 33 is provided on the upper part of the vertical push rod 31 to press it against the eccentric wheel 23. The eccentric wheel 23 drives the vertical push rod 31 to reciprocate up and down and rotate. The vertical push rod 31 drives the arch-breaking elastic bar assembly 32 to generate an irregular vibration and impact trajectory in the vertical direction to disperse the material. The discharge amount adjustment component 4 is provided in the bin 1 above the horizontal rotating feeding component 2. The discharge amount adjustment component 4 is provided with a discharge gate 41 for controlling the discharge amount. The material dispersed by the vertical arch-breaking component 3 falls into the horizontal rotating feeding component 2 through the discharge gate 41.

[0031] See Figure 3-4 As shown, the discharge gate 41 includes one or more, and the discharge gate 41 is located inside the bin 1 above the horizontal rotating feeding component 2. The two ends of the door hinge of each discharge gate 41 are respectively hinged to the bin wall of the bin 1. An adjusting rod 42 is provided between the door hinges of the discharge gates 41. At least one door hinge of the discharge gate 41 is connected to an opening adjustment mechanism 43, which drives the discharge gate 41 to open and close via the adjusting rod 42. The opening adjustment mechanism 43 includes a manual rotation mechanism or an automatic rotation mechanism.

[0032] The rebound mechanism 33 includes a spring seat 331, a compression spring 332, and an adjusting plate 333. The spring seat 331 is fixed to the bottom surface of the mounting crossbar 5, which is fixed to the upper part of the chamber 1. The compression spring 332 is located in the cavity of the spring seat 331. The adjusting plate 333 passes through the vertical push rod 31, and an adjusting nut 34 is provided in the vertical push rod 31 to press the adjusting plate 333 and the compression spring 332. The upper end of the vertical push rod 31 passes through the holes in the spring seat 331 and the mounting crossbar 5. The arch-breaking spring assembly 32 includes a spiral striking spring 321, which passes through the fixing hole in the rebound plate 322. The rebound plate 322 is fixed to the vertical push rod 31. The striking spring 321 is made of one or more spring steel wires or ropes, and the rebound plate 322 is made of a torsional elastic sheet, possessing both elasticity and rigidity.

[0033] The horizontal rotating shaft 21 is connected to the driving device, and each set of feeding wheel groups 22 is provided with two or more feeding blades 221. The eccentric wheel 23 has a guide groove 231 on its contour rotation surface, and the lower end of the vertical push rod 31 has a contact end that mates with the guide groove 231.

[0034] The hopper 1 is provided with an auxiliary guide sleeve 6, which is located above the horizontal rotating feeding component 2. The lower end of the vertical push rod 31 passes through the guide sleeve on the auxiliary guide sleeve 6. The discharge door 41 is located below the auxiliary guide sleeve 6, and the discharge door 41 has space to avoid the vertical push rod 31 when it is closed.

[0035] The method for breaking up arches in a feeding silo conveying device, as described above, includes the following steps:

[0036] S1. Adjust the preload of the springback mechanism 33 so that the lower end of the vertical push rod 31 is in close contact with the contour rotation surface of the eccentric wheel 23;

[0037] S2. Adjust the opening of the discharge gate 41 to control the discharge amount of material;

[0038] S3. The horizontal rotating shaft 21 and the feeding wheel assembly 22 are driven by an external power source to rotate, conveying material to the discharge port. At the same time, the eccentric wheel 23 pushes the vertical push rod 31 to move up and down reciprocally. Under the action of the vertical push rod 31 and the rebound mechanism 33, the anti-bridging elastic bar assembly 32 follows the up and down reciprocating motion. During the up and down reciprocating motion, the anti-bridging elastic bar assembly 32 has an irregular motion trajectory due to its elasticity (the anti-bridging elastic bar assembly 32 can generate irregular vibration impact in the vertical direction, and will rotate during the vibration). The irregular up and down vibration impact of the anti-bridging elastic bar assembly 32 breaks up the material in the bin. The broken material falls into the horizontal rotating feeding component 2 through the opening of the discharge gate 41 and is discharged by the feeding wheel assembly 22. The material after impact and dispersal is less likely to arch and block, which can better ensure continuous automatic discharge.

Any equivalent structural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
