Description

Technical Field

[0001] This utility model relates to the field of feed storage technology, specifically a vertical silo for feed storage. Background Technology

[0002] In the field of feed storage, vertical silos are a common type of storage equipment widely used in feed production, processing, and storage. However, traditional vertical silos suffer from a series of technical defects in actual use, seriously affecting the efficiency and safety of feed storage. The unreasonable design of the feeding mechanism in traditional vertical silos leads to blockages and feed residue problems during the feeding process. For example, some silos use wall vibrators as a feeding auxiliary device, but when processing powdered feeds with high moisture content or high viscosity, the vibrators not only fail to effectively solve the blockage problem, but also cause malfunctions such as weld detachment of the feeding chute and loosening of bolts due to prolonged high-frequency vibration. This increases equipment maintenance costs and safety hazards, and may even require manual cleaning, seriously affecting production efficiency. Therefore, a vertical silo for feed storage is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the embodiments, by Figure 1-4 A vertical silo for feed storage is provided, comprising a frame 1, a silo 2 fixedly connected to the inner side of the frame 1, the silo 2 being funnel-shaped, a discharge pipe 3 connected to the bottom end of the silo 2, a discharge mechanism 4 provided on the outer side of the discharge pipe 3, a drive mechanism 5 for driving the discharge mechanism 4 to move at the left and right ends of the silo 2, and two cover plates 6 hinged to the top of the frame 1.

[0024] The feeding mechanism 4 includes side plates 41. Both the front and rear ends of the feeding tube 3 are fixedly connected to the side plates 41. Two rotating shafts 42 are rotatably connected to the opposite side of the two side plates 41. Swing plates 43 are fixedly connected to the outer sides of the four rotating shafts 42. The bottom ends of the two adjacent swing plates 43 are fixedly connected to the feeding opening and closing plates 44. The contact parts of the two feeding opening and closing plates 44 are in contact with each other.

[0025] With the above setup, the two top covers 6 are in the open state, and the discharge opening and closing plate 44 is in the closed state under the action of the drive mechanism 5. The two discharge opening and closing plates 44 fit tightly together, completely sealing the outlet of the discharge pipe 3. Feed (granular, powdered, or mixed feed) is added through the open inlet at the top of the hopper 2. The feed falls into the funnel-shaped hopper 2 under its own weight. The funnel shape design of the hopper 2 helps the feed to slide naturally under gravity and concentrate above the discharge pipe 3. The tightly closed discharge opening and closing plate 44 prevents feed from leaking from the bottom and closes the top. The cover plate 6 of the feed hopper 2 can provide some dustproof, moistureproof, or prevent foreign objects from falling in. The feed is temporarily or short-term stored in the enclosed space of the feed hopper 2. When it needs to be taken out, the drive mechanism 5 is operated. The force of the drive mechanism 5 acts on the swing plate 43. The drive action at both ends will force the four rotating shafts 42 connected to them to rotate simultaneously on the two side plates 41. Since the rotating shafts 42 are fixedly connected to the swing plate 43, the swing plate 43 rotates accordingly, and the feeding opening and closing plate 44 opens. When the swing plates 43 on both sides rotate, they will drive the two feeding opening and closing plates 44 fixedly connected to them. 4. The two feed opening and closing plates 44, which were originally tightly fitted together, swing to the left and right respectively, separating to the left and right (similar to two doors opening in opposite directions), forming an opening in the middle. The feed accumulated at the bottom of the hopper 2 and above the feed pipe 3 falls into the feed pipe 3 below through the newly formed opening under the action of gravity. The feed flows out of the feed pipe 3 and enters the subsequent conveying pipeline, feeding equipment, or is discharged directly. By adjusting the stroke of the drive mechanism 5 (i.e., controlling the size of the opening of the feed opening and closing plates 44), the feed feeding speed can be precisely controlled. Flow rate (small opening, small flow rate; large opening, large flow rate). When it is necessary to stop feeding, the drive mechanism 5 is operated in the reverse direction. The drive mechanism 5 causes the swing plate 43 to rotate in the opposite direction, which drives the two feeding opening and closing plates 44 to swing towards the center and finally re-close tightly together. The feeding outlet is completely closed, and the feed stops flowing out. Compared with the existing technology, the side plate 41, the rotating shaft 42, the swing plate 43, and the feeding opening and closing plates 44 have relatively simple structures and are exposed. The rotating shaft 42 uses bearings or bushings, which are not easy to accumulate material and are easy to inspect and maintain (such as cleaning a small amount of residual material, lubrication, etc.).

[0026] Reference Figure 1-4 The drive mechanism 5 includes a fixed plate 51. Two fixed plates 51 are fixedly connected to both the left and right ends of the hopper 2. A fixed shaft 52 is fixedly connected between two adjacent fixed plates 51 on the left and right sides. A rotating block 53 is rotatably connected to the outside of the fixed shaft 52. A pressure rod 54 is fixedly connected to one end of the rotating block 53. A connecting arm 55 is hinged to the other end of the rotating block 53. The connecting arm 55 is hinged to the unloading opening and closing plate 44.

[0027] With the above structural setup, when the manual pressing of the pressure rod 54 is performed, the rotating block 53 acts as a primary lever arm, rotating clockwise (or counterclockwise, depending on the viewing angle) from the pivot point formed by the rotating block 53 and the fixed axis 52. When the rotating block 53 rotates, the connecting arm 55, which is fixedly connected to its other end, moves accordingly. At this time, the direction of movement of the connecting arm 55 is to push or pull the material opening and closing plate 44 that is hinged to it. The force of the connecting arm 55 forces the material opening and closing plate 44 connected to it to swing outward. When the left and right drive mechanisms 5 act synchronously, the left drive mechanism 5: the connecting arm 55 pushes the left material opening and closing plate 44 to the right and outward, and the right drive mechanism 5: the connecting arm 55 pushes the left material opening and closing plate 44 to the right and outward. 55 pushes the right-side feeding opening and closing plate 44 to the left and outward; the feeding opening and closing plates 44 on both sides swing to the left and outward respectively, and the diamond or rectangular opening in the middle gradually forms and expands. When it is necessary to stop feeding, lift (or release) the pressure rod 54. Under the action of spring, gravity or reverse operation force, the rotating block 53 rotates in the opposite direction around the fixed axis 52, returning to the initial angle or close to the initial angle. The connecting arm 55 moves accordingly and retracts to the initial position. The force of the connecting arm 55 (at this time it becomes a pulling force or an inward supporting force) will pull the feeding opening and closing plate 44 connected to it back to the center or push it to close. The two feeding opening and closing plates 44 on the left and right sides are tightly fitted again at the center line to complete the seal.

[0028] Reference Figure 1-4 The rotating block 53 has a disk 56 fixedly connected to both its front and rear ends. Both disks 56 are rotatably connected to the outside of the fixed shaft 52. Both disks 56 have a guide groove 57. The guide groove 57 is an arc-shaped groove. A guide rod 58 is slidably connected to the inside of the guide groove 57. Two collars 59 are rotatably limited connected to the outside of the guide rod 58. The two collars 59 are fixedly connected to the opposite side of the two fixed plates 51 respectively.

[0029] The key innovation of the above structural design lies in the arc-shaped guide groove 57 on each disc 56. Its center coincides with the axis of the fixed axis 52, forming a precise concentric arc track. The guide rod 58 passes through the collar 59 mounted on the two side fixing plates 51, possessing axial freedom but no radial movement. Serving as a rigid reference axis, the guide rod 58 is embedded in the guide groove 57 of the left and right discs 56, forming a sliding connection. The double discs 56, concentric arc-shaped guide grooves 57, and guide rods 58 form a "dual-track guide system," ensuring that the rotating block 53 rotates precisely along the predetermined center and plane without wobbling or deviation.

[0030] Reference Figure 1-4 Among them, the top of each of the two cover plates 6 is fixedly connected with a handle 7;

[0031] With the above structural design, the handle 7 effectively extends the lever arm of the cover plate 6. The operator only needs to apply a small force (such as pressing down or pulling up the handle 7) to easily pry open the heavier cover plate 6 through leverage.

[0032] Reference Figure 1-4 Among them, two support plates 8 are fixedly connected to the inner side of the upright frame 1, and the two support plates 8 are in contact with the front and rear inclined surfaces of the hopper 2 respectively;

[0033] With the above structural design, the two support plates 8 provide further support for the front and rear inclined surfaces of the hopper 2, thereby extending the service life of the hopper 2.
