Description

Technical Field

[0001] The utility model relates to the field of feeding devices for feed towers, in particular to a multifunctional precise feeding device for a feed tower. Background Art

[0002] A feeder is provided at the bottom of the existing feed tower, and an agitator is provided inside the feed tower. The feeder is used to control the volume of feed entering the feed pipe from the feed tower. Currently, a movable gate plate is provided at the bottom of the feed tower for the feeder, and the feeding speed of the feed tower is controlled by the opening and closing area of the gate plate. The agitator rotates to stir the feed inside the feed tower, causing the feed near the side wall of the feed tower to move, preventing the feed from accumulating near the side wall of the feed tower and not entering the feeder for a long time. This is because the feed that does not enter the feeder for a long time stays in the feed tower for too long and is prone to deterioration.

[0003] The existing feeder and agitator work independently of each other, and the sum of the volumes occupied by the two is relatively large and the cost is relatively high. Summary of the Utility Model

[0029] Such as Figures 1 to 6As shown in the figure, this embodiment provides a multi-functional precise feeding device for a feed tower, including: a feeding cylinder, a rotating shaft 3, a feeding rack 4, a baffle 5, stirring blades 6, and a motor 7. The motor 7 drives the rotating shaft 3 to rotate. The rotating shaft 3 passes through the feeding cylinder and rotates relative to the feeding cylinder. The feeding rack 4 and the stirring blades 6 are respectively fixedly connected to the rotating shaft 3. The feeding cylinder is formed with a feeding hole. The baffle 5 is located above the feeding hole and blocks the feeding hole. The feeding rack 4 is located between the baffle 5 and the feeding hole. The feeding cylinder is fixedly connected to the bottom of the feed tower and is communicated with the inside of the feed tower. The stirring blades 6 extend into the inside of the feed tower.

[0030] Based on the above technical solution, the feeding cylinder includes a cylinder wall 1 and a bottom plate 2. The lower end of the cylinder wall 1 is attached to the bottom plate 2 and fixedly connected to the bottom plate 2. The rotating shaft 3 passes through the bottom plate 2. The feeding hole is located on the bottom plate 2. The baffle 5 is fixedly connected to the cylinder wall 1.

[0031] Based on the above technical solution, the feeding rack 4 includes an annular plate 41 and a connecting plate 42. The centers of multiple annular plates 41 are the same but their diameters are different. The connecting plate 42 is respectively fixedly connected to different annular plates 41. The annular plate 41 and the connecting plate 42 enclose a vertically penetrating feeding cavity 40.

[0032] Based on the above technical solution, an annular inner protrusion 11 is formed on the inner side of the cylinder wall 1. The inner protrusion 11 is located above the outermost annular plate 41 of the feeding rack 4. The shielding of the inner protrusion 11 prevents the feed from entering the gap between the outermost annular plate 41 and the cylinder wall 1, avoiding the blockage of the gap by the feed.

[0033] Based on the above technical solution, it further includes a flexible cover 8, a feeding pipe 9, and a discharging pipe 21. The upper end of the discharging pipe 21 is fixedly connected to the bottom plate 2. The discharging pipe 21 is inserted into the feeding hole. The lower end of the discharging pipe 21 is fixedly connected to the flexible cover 8. The flexible cover 8 can be deformed, reducing the precision requirement for the position during the installation of the discharging pipe 21 and also reducing the influence of the vibration of the feeding cylinder during discharging on the discharging pipe 21.

[0034] Based on the above technical solution, it further includes a speed reducer 71. The speed reducer 71 is located below the bottom plate 2 and fixedly connected to the bottom plate 2. The output shaft of the speed reducer 71 is fixedly connected to the rotating shaft 3. The housing of the motor 7 is fixedly connected to the speed reducer 71 or the bottom plate 2.

[0035] Based on the above technical solution, the stirring blades 6 include an inclined plate 61, a vertical plate 62, and a radial plate 63. The upper and lower ends of the vertical plate 62 are integrally formed with the inclined plate 61 and the radial plate 63 respectively. The ends of the inclined plate 61 and the radial plate 63 far from the vertical plate 62 are respectively fixedly connected to the rotating shaft 3. The end of the inclined plate 61 close to the rotating shaft 3 is inclined upward.

[0036] Based on the above technical solution, the stirring blade 6 further includes a bent plate 64, the bent plate 64 is integrally formed with the side surface of the inclined plate 61, and the side of the bent plate 64 away from the inclined plate 61 is inclined upward.

[0037] Based on the above technical solution, the connecting plates 42 are arranged in a circular and uniform distribution with the center of the annular plate 41 as the center.

[0038] Based on the above technical solution, the baffle 5 covers a part of the bottom plate 2.

[0039] During operation, the motor 7 rotates to drive the feeding frame 4 and the stirring blade 6 to rotate synchronously. When the feeding cavity 40 passes through the area not blocked by the baffle 5, the feed falls by gravity into the interior of the feeding cavity 40. Then, the feed moves along with the feeding cavity until the feeding cavity 40 of the feed reaches above the feeding hole. The feed in the feeding cavity 40 passes through the feeding pipe 21 and the flexible cover 8 in sequence under the action of gravity, and finally enters the feeding pipe 21.

[0040] During operation, the amount of the fed feed is controlled by controlling the number of rotation turns of the feeding frame 4. The stirring blade 6 stirs the feed inside the silo synchronously, avoiding uneven discharge of the feed inside the silo.

[0041] The above has described the present invention by way of example, but the present invention is not limited to the above specific embodiments. Any modification or variation based on the present invention falls within the scope of protection required by the present invention.
