[0030] like Figures 1 to 6 As shown, the mobile material distributor 5 of this embodiment is applied to a grain silo. The mobile material distributor 5 includes a central support frame 540 and a material distribution pipe 550 connected to the central support frame 540. The inner wall of the central support frame 540 is provided with a traveling wheel 510 for cooperating with the outer wall of the central column 3 of the grain silo. An elastic support structure 520 and an adjustment mechanism 530 are provided between the traveling wheel 510 and the central support frame 540. The adjustment mechanism 530 is used to adjust the elasticity of the elastic support structure 520 and / or to adjust the position of the traveling wheel 510.

[0031] The grain silo also includes a silo 1, a silo top 2, a central column 3, and a power platform 4. Based on existing technology, the lifting and moving of the feeder 5 is controlled by the power mechanism 410 and the transmission mechanism 420 on the power platform 4. It should be understood that the central column is usually a square structure, and the central support frame is matched with a square structure. Four wheels are set on each wall to cooperate with the central column for stability.

[0032] Understandably, this mobile fabric spreader 5, by evenly distributing the traveling wheels 510 on its inner wall circumferentially, maintains stable lifting and lowering stability and avoids scratches during the lifting and lowering process by cooperating with the outer wall of the central column 3. Furthermore, by setting an elastic support structure 520, the traveling wheels 510 can adapt to the surface undulations of the central column 3 caused by manufacturing and assembly errors, and smoothly pass through deformed parts. By setting an adjustment mechanism 530 to adjust the elasticity of the elastic support mechanism to make it more adaptable and / or to adjust the position of the traveling wheels 510, it can adapt to different circumferential dimensions of the central column 3. This makes the fabric spreader 5 more tolerant of the flatness of the outer surface of the central column 3 during the movement, with lower usage requirements and greater applicability.

[0033] In some embodiments, the elastic support structure 520 includes a support rod 521 that is axially slidably connected to the central support frame 540 perpendicular to the central column 3. A support spring 522 is sleeved on the support rod 521. The support spring 522 keeps the walking wheel 510 abutting against the surface of the central column 3. Specifically, the adjustment mechanism 530 controls the position of the walking wheel 510 by controlling the axial position of the support rod 521, resulting in a simplified structure.

[0034] In some embodiments, the adjustment mechanism 530 includes an adjustment plate 531 connected to the wall of the central support frame 540, a first limiting component, a second limiting component, and a third limiting component. The adjustment plate 531 is used to pass through the support rod 521. The first limiting component is used to limit the adjustment plate 531 in a first direction. The second limiting component is used to limit the adjustment plate 531 in a second direction. The third limiting component is used to limit the end of the support rod 521 away from the traveling wheel 510. By setting the adjustment plate 531 parallel to the wall of the central support frame 540, and using the first limiting component and the second limiting component to limit its two surfaces respectively, it is fixed at a preset distance relative to the central support frame 540, thereby realizing the axial position adjustment of the support rod 521, that is, realizing the position adjustment of the traveling wheel 510, with a simplified structure.

[0035] Specifically, the first limiting component includes a locking bolt 532 passing through the walls of the adjusting plate 531 and the central support frame 540, with the small end of the locking bolt 532 protruding from the wall of the central support frame 540 and connected to the first nut 533; the second limiting component includes a tightening bolt 534 threadedly connected to the wall of the central support frame 540, with the small end of the tightening bolt 534 abutting against the adjusting plate 531, and a second nut 535 provided on the tightening bolt 534 to limit the amount of insertion of the tightening bolt 534; the third limiting component includes a third nut 536 threadedly connected to the support rod 521; the position of the adjusting plate 531 can be adjusted by loosening the first nut 533 at the small end of the locking bolt 532 and screwing the second nut 535 into the large end of the tightening bolt 534; specifically, when adjusting towards the direction of the traveling wheel 510, the first nut 533 is loosened at the small end of the locking bolt 532, and after adjusting to the appropriate position, the first nut 536 is screwed into the large end of the tightening bolt 534. The adjustment is completed by inserting the second nut 535, then screwing the tightening screw into the tightening adjusting plate 531, and then tightening the second nut 535 towards the small end of the tightening bolt 534. When adjusting towards the central support frame 540, simply loosen the tightening screw. After adjusting to the appropriate position, tighten the second nut 535 towards the small end of the tightening bolt 534 and tighten the first nut 533 towards the large end of the locking bolt 532. The operation is convenient and quick. The adjustment and limiting can be completed by two sets of nuts through the adjusting plate 531, which simplifies the structure and makes it easy to implement. On the other hand, the end of the support rod 521 is provided with a limiting seat, which is used to abut against the support spring 522 and also serves as a hinge seat. The other end of the support spring 522 abuts against the adjusting plate 531. The axial position of the support rod 521 relative to the adjusting plate 531 can be adjusted by loosening and tightening the third nut 536, thereby adjusting the compression of the support spring 522. In order to ensure a stable fixation, two third nuts 536 are provided in this embodiment.

[0036] In some embodiments, locking bolts 532 are provided on both sides of the support rod 521; tightening bolts 534 are provided on both sides of the support rod 521, that is, the locking bolts 532 and the tightening bolts 534 are symmetrically distributed on both sides of the support rod 521 so as to support and limit the adjustment plate 531 stably.

[0037] In some embodiments, the elastic support structure 520 includes an L-shaped connecting rod. The walking wheel 510 is connected to the turning point of the connecting rod. The first end of the connecting rod is hinged to the central support frame 540, and the second end of the connecting rod is hinged to the support rod 521. It should be understood that by setting the L-shaped connecting rod, the force generated by the walking wheel 510 and the central column 3 is distributed to the connection points at both ends of the connecting rod. This not only makes it easier to support the walking wheel 510, but also significantly reduces the shear force on the support rod 521 during the upgrade process, thereby improving service life and preventing damage. The central support frame 540 is provided with a fixed seat, which has a column for hinged to the first end of the connecting rod. It should be understood that the length of the connecting rod in the direction of the first end is greater than the length in the direction of the second end, so as to match the length of the support rod 521 and make the force on both ends relatively balanced.

[0038] In some embodiments, the walking wheel 510 is an antistatic elastic wheel, specifically an antistatic rubber wheel, to avoid fire caused by hard contact and friction; in other embodiments, the surface of the elastic wheel may be provided with an antistatic layer or the elastic wheel may be made of an antistatic material; the elastic wheel may be made of rubber or other elastic materials that can achieve the same effect.

[0039] In some embodiments, the material distributor 5 includes multiple main discharge ports, and the main discharge ports are connected to a first distribution trough 551. The first distribution trough 551 includes symmetrically distributed first distribution branches. The main discharge ports are connected to the vertically distributed first distribution troughs 551. The tail end of the first distribution branch of the upper first distribution trough 551 is connected to a second distribution trough 552. The second distribution trough 552 includes symmetrically distributed second distribution branches. It should be understood that the main discharge ports are connected to the first distribution troughs 551, and the number of main discharge ports matches the number of discharge ports at an axial position on the central column 3, which is usually four. The first distribution trough 551 has two first distribution branches, which makes the material evenly dispersed. By arranging the first distribution troughs 551 vertically and distributing them vertically, and connecting the tail end of each distribution branch of the upper first distribution trough 551 to the second distribution trough 552, the material can be discharged at medium and long distances and evenly dispersed.

[0040] In some embodiments, the first distributing branch of the first distributing trough 551 includes multiple first connecting sections, and the second distributing branch of the second distributing trough 552 includes multiple second connecting sections. By configuring the first distributing trough 551 and the second distributing trough 552 as multiple connecting sections, it is convenient for manufacturing and transportation. Similarly, the central column 3 of the grain silo used in this embodiment includes multiple connecting columns 310 along the axial direction to facilitate production and transportation. The multiple connecting columns 310 are connected to form the central column 3. On the other hand, the top and bottom of the connecting column 310 located at the preset grain loading height line are... Each structure is equipped with a heat insulation structure 320. It should be noted that, since the temperature at the top of the silo is higher than the temperature of the grain inside, the high temperature at the top is transferred through the central column 3, creating a temperature difference between the central column 3 below the grain loading line and the grain, which leads to condensation, condensation, and blockage. In this embodiment, the heat insulation structure 320 is a polymer heat insulation board. The polymer heat insulation board reduces the temperature of the silo top 2 transferred through the central column 3 to the central column 3 below the grain loading line, thus solving the problem of condensation, condensation, and blockage of the central column 3. In other embodiments, the heat insulation structure 320 can also be implemented using a heat insulation layer made of other heat insulation materials.

[0041] On the other hand, a preferred embodiment of this utility model also provides a grain silo, which uses the aforementioned movable feeder 5; a ventilation and fumigation channel 110 is provided radially at the bottom of the silo 1, and the ventilation and fumigation channel 110 is respectively connected to the central column 3, the interior of the silo 1, and the side wall of the silo 1; the bottom of the silo 1 of this grain silo has a ventilation and fumigation channel 110 radially opened and connected to the central column 3, the interior of the silo 1, and the side wall of the silo 1. When the grain is regularly ventilated and fumigated, the fumigation hot air is introduced into the interior of the silo 1 and the interior of the central column 3 through the side wall of the silo 1. The grain in the silo and the grain in the central column 3 are ventilated and fumigated. By setting up a material distribution ventilation device, the fumigation hot air enters the central column 3 through the bottom of the central column 3 and then diffuses circumferentially through the ventilation structure, so that the grain in the central column 3 and the grain in the silo form an ecological balance; The power platform 4 is provided with connecting parts 430 evenly distributed around its circumference for rigid connection with the silo roof 2. It should be noted that in the prior art, the power platform 4 is connected to the silo roof 2 by a chain hoist, while the central column 3 is rigidly connected and passes through the power platform 4. When the power platform 4 is running, there is high-altitude swaying and vibration. The vibration and swaying of the power platform 4 causes resonance and swaying of the central column 3, resulting in the risk of collapse of the central column 3. In this embodiment, the power platform 4 is rigidly connected to the silo body by the connecting parts 430, which effectively solves the problem of high-altitude swaying and vibration of the power platform 4 during operation and avoids the resonance and swaying of the central column 3 caused by the vibration and swaying of the power platform 4. The connecting parts 430 can be hoists. The first end of the hoist is rigidly connected to the ring beam of the silo roof 2, and the second end of the hoist is rigidly connected to the power platform 4. Both ends of the hoist are fastened with bolts.
