Technical Field

[0001] The invention relates to the technical field of feeding equipment, and in particular to an arch-breaking silo and pig feeding equipment. Background Art

[0002] At present, in the pig breeding industry, based on economic cost and convenience considerations, the automatic continuous feeding of granular and powdery materials such as feed and medicine in the feeding mechanism is usually achieved by their own gravity. However, due to the combined influence of factors such as the material's own gravity, water content, particle size distribution, viscosity, friction coefficient with the inner wall of the silo of the feeding mechanism, as well as the inclination angle of the inner wall of the silo, the size of the silo outlet, etc., granular and powdery materials are prone to arching during automatic feeding.

[0003] At present, the traditional arch breaking method of the silo is that the long arch breaking member extending radially on the central power rotating shaft on the material-moving rod at the bottom of the silo rotates around the shaft under the action of the motor, thereby breaking the feed arched along the inner wall of the silo. In this method, the long arch breaking member should extend from the center of the silo to a position close to the inner wall of the silo, so the length of the arch breaking member is large, and the resistance of the arch breaking member in the rotating state is proportional to the square of its length, and the arch breaking member is generally extended in multiple groups, resulting in high requirements for the motor torque, power supply power, controller power, and wiring current carrying capacity of the silo; that is, in the prior art, the traditional arch breaking method of the silo has a large resistance and high power requirements for arch breaking, resulting in poor efficiency and effect of silo arch breaking.

[0008] In a further technical solution, in the arch-breaking silo, the rolling device is a symmetrically arranged rolling shaft.

[0009] In a further technical solution, in the arch-breaking silo, the arch-breaking blades are only arranged on the second arch-breaking axis, and are evenly staggered along the axial direction of the second arch-breaking axis.

[0023] Various non-limiting embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1-Figure 3 , an embodiment of the present invention provides an arch-breaking silo, which includes a silo body 1 and an arch-breaking mechanism disposed in the silo body 1; The arch-breaking mechanism includes a driving motor 21 disposed at the top of the silo body 1, an arch-breaking structure connected to a power output shaft 22 of the driving motor 21, a transmission shaft stopper 24 disposed at the bottom of the silo body 1, and a transmission shaft 25 connected to the arch-breaking structure and coaxially inserted into the transmission shaft stopper 24; The arch breaking structure includes a first universal joint 231, a second universal joint 232, a third universal joint 233, a first arch breaking shaft 234, a second arch breaking shaft 235, and an arch breaking leaf 236. One end of the first arch breaking shaft 234 is connected to the power output shaft 22 through the first universal joint 231, the other end of the first arch breaking shaft 234 is connected to one end of the second arch breaking shaft 235 through the second universal joint 232, and the end of the second arch breaking shaft 235 away from the second universal joint 232 is connected to the transmission shaft 25 through the third universal joint 233. The arch breaking leaf 236 is arranged on the first arch breaking shaft 234 and / or the second arch breaking shaft 235.

[0025] In the specific implementation, in this embodiment, the transmission shaft limiter 24 is used to limit the swing of the transmission shaft 25 in the horizontal direction, but the transmission shaft 25 can slide up and down in the transmission shaft limiter 24 appropriately; the arch-breaking silo of the present invention realizes the flexible connection between the power output shaft 22 and the arch-breaking shaft by adopting the arch-breaking structure connected by multi-stage universal joints, which effectively reduces the resistance caused by the accumulation of materials in the silo body 1; wherein, the first universal joint 231 allows the angle deviation between the power output shaft 22 and the first arch-breaking shaft 234, and the second universal joint 232 and the third universal joint 234 allow the power output shaft 22 to have an angle deviation between the first arch-breaking shaft 234 and the second universal joint 232. The section 233 further transmits power and allows an angle deviation between the first arch-breaking shaft 234 and the second arch-breaking shaft 235, as well as an angle deviation between the second arch-breaking shaft 235 and the transmission shaft 25. This design enables the arch-breaking mechanism to adapt to the complex material accumulation inside the silo body 1, reduces the motor load caused by material resistance, and reduces the power requirement; at the same time, the arch-breaking blades 236 are arranged on the first arch-breaking shaft 234 and / or the second arch-breaking shaft 235, which can more effectively break the material in the silo body 1 and improve the arch-breaking efficiency. In general, this design of the arch-breaking silo of the present invention improves the arch-breaking efficiency and effect, reduces energy consumption, and solves the problems of large resistance, high power requirements, and poor efficiency and effect in the traditional silo arch-breaking method by increasing the flexibility of power transmission and the arch-breaking shaft, as well as the arrangement of the arch-breaking blades.

[0026] Further, in one embodiment, the arch breaking silo, wherein the first arch breaking shaft 234 is coaxially sleeved with a compression spring 237 and a gasket 238, one end of the compression spring 237 near the first universal joint 231 is fixed by a spring stopper 239 arranged on the first arch breaking shaft 234, one end of the compression spring 237 near the second universal joint 232 is connected to the gasket 238, and a rolling device 230 abutting against the gasket 238 is arranged on one side of the second universal joint 232 near the first arch breaking shaft 234.

[0027] Furthermore, in the arch-breaking silo, an end of the transmission shaft 25 away from the third universal joint 233 is connected with a material-moving rod 3 .

[0028] In specific implementation, in this embodiment, when there is less material in the silo body 1, that is, in a light resistance state with less material, due to the elastic force of the compression spring 237, after the pressure is applied to the long protrusion at the end of the second universal joint 232 through the gasket 238 and the rolling device 230, the first arch breaking shaft 234 will be offset to one side of the second universal joint 232, so that the entire arch breaking structure is in a revolution locking state. At this time, the arch breaking structure stirs all the arched areas in the silo body 1 through the first arch breaking shaft 234, the second arch breaking shaft 235 and the arch breaking leaves 236, thereby realizing efficient and rapid arch breaking of the silo; When there is a lot of material in the silo body 1, that is, in a state of high resistance when there is a lot of material or the silo is full, the pressure of the compression spring 237 is insufficient to limit the tilting of the long protrusion at the end of the second universal joint 232, so that the other two universal joints (the first universal joint 231 and the third universal joint 233) linked with the second universal joint 232 are unlocked synchronously, so that the entire arch breaking structure is in a self-rotating unlocked state. At this time, the first arch breaking shaft 234 and the second arch breaking shaft 235 can rotate around their own axis, and drive the radially extending arch breaking leaves 236 thereon to stir a small part of the arch area close to the inner wall of the silo body 1. When this part of the material is rotated and discharged through the material-discharging rod 3 at the bottom end of the silo body 1, due to the reduction of the resistance near the first arch breaking shaft 234 and the second arch breaking shaft 235, the entire arch breaking structure can be pushed to the rear position in the revolution locking state, gradually stirring the arch area, and finally stirring all the arch parts and discharging the silo body 1 under the rotation of the material-discharging rod 3; Compared with the traditional single arch breaking method, the arch breaking silo of the present invention has a two-stage arch breaking method. During the gradual arch breaking process, only the arch foundation area near the inner wall of the silo body 1 can be destroyed, which is more flexible. Therefore, it can not only reduce the pressure on the power-related configuration of the equipment, but also the advantage becomes more obvious as the volume of the silo increases, thereby improving the arch breaking efficiency and the adaptability of the equipment.

[0029] Furthermore, in one embodiment, in the arch-breaking silo, the rolling device 230 is a symmetrically arranged rolling shaft.

[0030] In specific implementation, in this embodiment, the arch-breaking structure of the arch-breaking silo is further optimized by designing the rolling device 230 as a symmetrically arranged rolling shaft; this symmetrical rolling shaft design can provide uniform support and rolling ability in multiple directions, so that the second universal joint 232 can adjust the angle more flexibly when subjected to force, and can be locked and unlocked to adapt to the changes in the material accumulation inside the silo body 1. This design not only enhances the adaptability and reliability of the arch-breaking structure, but also improves the arch-breaking efficiency, making the arch-breaking operation more stable and efficient, especially when the material state in the silo body 1 changes frequently or the material properties are different, the symmetrically arranged rolling shaft can provide better performance.

[0031] Furthermore, in one embodiment, in the arch-breaking silo, the arch-breaking blades 236 are only arranged on the second arch-breaking axis 235 , and are evenly staggered along the axial direction of the second arch-breaking axis 235 .

[0032] Furthermore, in the arch-breaking silo, the arch-breaking blade 236 is rod-shaped, and the arch-breaking blade 236 is vertically connected to the second arch-breaking shaft 235 .

[0033] Furthermore, in the arch-breaking silo, the axis lines of any two of the arch-breaking leaves 236 are not parallel.

[0034] In the specific implementation, in this embodiment, the layout and structure of the arch-breaking blades 236 are further optimized to improve the arch-breaking efficiency and effect of the arch-breaking silo, specifically: 1. Position setting of the arch-breaking blade 236: The arch-breaking blade 236 is only set on the second arch-breaking shaft 235. Such a design simplifies the structure and helps to concentrate power, making the arch-breaking force more concentrated and effective; 2. Arrangement of the arch-breaking blades 236: The arch-breaking blades 236 are evenly staggered along the axis of the second arch-breaking shaft 235. This evenly staggered arrangement helps to cover a wider arch-forming area during arch-breaking, ensures that the material is evenly stirred, reduces dead angles, and improves the comprehensiveness and efficiency of arch-breaking. 3. Shape and connection mode of the arch-breaking blade 236: The arch-breaking blade 236 is rod-shaped and vertically connected to the second arch-breaking shaft 235. This design enables the arch-breaking blade 236 to cut and stir the material more effectively when rotating. The vertical connection also helps the arch-breaking blade 236 to better penetrate the material when breaking the arch, thereby improving the arch-breaking effect. 4. Axis line design of the arch-breaking blades 236: The axis lines of any two arch-breaking blades 236 are not parallel. This non-parallel design increases the space between the arch-breaking blades 236 and reduces mutual interference, so that each arch-breaking blade 236 can act on the material independently and effectively, thereby improving the flexibility and coverage of arch-breaking; That is, the design improvement of this embodiment makes the arch-breaking silo more efficient in the arch-breaking process, can better adapt to different material characteristics and silo conditions, reduce the possibility of material arching, and improve the fluidity of the material, thereby improving the operating efficiency of the entire silo.

[0035] Based on the arch-breaking silo provided in the above-mentioned embodiment, another embodiment of the present invention further provides a pig feeding device, which includes the arch-breaking silo as described in any of the above items, and the details are as described above and will not be repeated here.

[0036] In summary, the present invention provides an arch-breaking silo and pig feeding equipment, which can solve the problem in the prior art that the traditional silo arch-breaking method has large resistance and high power requirements for arch breaking, resulting in poor efficiency and effect of silo arch breaking; at the same time, compared with the traditional single arch-breaking method, the arch-breaking silo of the present invention is more flexible in that the arch-breaking structure of this two-stage arch-breaking method can only destroy the arch foundation area near the inner wall of the silo body 1 during the gradual arch-breaking process, so it can not only reduce the pressure on the power-related configuration of the equipment, but also the advantage becomes more obvious as the volume of the silo increases, thereby improving the arch-breaking efficiency and the adaptability of the equipment.
