A multi-directional feeding dispenser for pregnant sows used in the sow automated precision feeding system

Abstract

A multi-directional feeding batcher for pregnant sows used in an automated precision feeding system for sows includes a collection bin, a rotating bin, a one-way wheel assembly, an auger shaft, a discharge port, and a DC reduction motor. The feed inlet of the collection bin corresponds to the feed outlet of the automatic feed line feed pipe, and the discharge port of the rotating bin corresponds to the feed inlet of the precision bucket. The collection bin is made into a reducer with a square upper section and a circular lower section, which effectively increases the filling volume of the collection bin material. The rotating bin can make the batcher rotate in multiple directions to select a trough for pregnant sows, and the angle can reach 340 degrees. The collection bin and the rotating bin between the automatic feed line and the precision bucket can control the automatic feed line and precision feeding separately, and the strong electricity controlling the automatic feed line will not affect the precision of the batcher added to the precision bucket. The collection bin, the rotating bin, and the auger shaft are all made into injection molded parts to prevent corrosion and rust in the long-term humid environment of the pig house.

Description

Technical Field

[0001] The invention relates to a multi-directional feeding batcher for pregnant sows applied to an automatic precision feeding system for sows, belonging to the technical field of animal husbandry machinery. Background Art

[0002] At present, an automated precision feeding system for sows is known, which uses a computer-operated electrical control system to perform precision feeding according to the sow's feed demand. The feed port of the batcher is directly connected to the discharge port of the automatic feed line. When the material transported by the automatic feed line enters the batcher, the batcher operates at the same time to transport the material to the precision bucket for weighing and feeding. This access method causes the automatic feed line and the feeding system to work at the same time. The strong electricity used to operate the automatic feed line will affect the precision of the batcher added to the precision bucket. In addition, some small pig houses are compact and are not suitable for automatic feed lines with more bends. Therefore, it cannot be guaranteed that each pregnant sow position has a precision feeding system for directional feeding, and the batcher needs to rotate in different directions to align the trough. The iron batcher corrodes and rusts in the long-term humid environment of the pig house. Summary of the invention

[0003] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a multi-directional feeding dispenser for pregnant sows.

[0004] The technical solution adopted by the present invention is that the multi-directional feeding distributor for pregnant sows is mainly composed of a collection bin, a rotating bin, a one-way wheel assembly, an auger shaft, a discharge port, and a DC reduction motor. The collection bin is composed of a reducer with a square upper section and a circular lower section and an inner cylinder. The feed inlet with a length of 375 mm and a width of 60 mm is connected to the feed outlet of the automatic feed line feed pipe. The automatic feed line feed pipe is opened for feeding every 60 mm. The feed inlet of each collection bin corresponds to the 5 feed outlets on the automatic feed line feed pipe. The two sides of the long side of the feed inlet are the lower connection cards of the automatic feed line, which are fixed to the automatic feed line feed pipe by bolts with the connection cards on the automatic feed line. The rotary bin is composed of an outer cylinder, a reducer with a circular upper section and a square lower section, and a transverse feed pipe. The inner side of the outer cylinder has two opposing upper and lower sliders. The outer surface of the inner cylinder of the collecting bin has two parallel upper and lower slideways. The lower slideway has two openings of different sizes symmetrically opened on both sides of the vertical direction of the rotary bin axis. The large opening is the entrance and exit of the lower slider, and the small opening is the lower entrance and exit of the upper slider. The upper slideway opening is located directly above the lower entrance and exit of the upper slider and is equal in size to the entrance and exit of the upper slider. There are upper slideway limit blocks on both sides of the entrance and exit. The width of the lower slider is enough to enter and exit from the lower slider entrance and exit, but the lower slider cannot fall out from the lower entrance and exit of the upper slider during the rotation of the rotary bin. The upper slider slides circumferentially on the upper slideway between the slideway limit blocks, and the opposite lower slider slides circumferentially on the lower slideway between the entrance and exit of the lower slideway. The discharge port can rotate in multiple directions with the batcher to select the feeding trough for pregnant sows, and the angle can reach 340 degrees. The DC reduction motor drives the auger shaft to convey the material that falls into the horizontal feed pipe in the rotating bin into the precision bucket for precision feeding. During the process of the computer controlling the forward rotation of the auger shaft to convey the material, the one-way wheel assembly does not work, and the material is weighed in the precision bucket. When the feed reaches the set value, the computer controls the DC reduction motor to drive the auger shaft to reverse, and the one-way wheel assembly reverses to realize the discharge. During the reversal of the auger shaft, the feed in the horizontal feed pipe is conveyed back. To ensure that the feed does not accumulate in the reverse direction, a space of 6 auger pitches is left at the center of the rotating bin outlet in the direction of the DC reduction motor. The collection bin with an automatic feed line lower connection card, the rotating bin composed of an outer cylinder and a horizontal feed pipe, and the auger shaft are all made of injection molded parts of pp plastic material with 1%-4% ethylene added.

[0005] Compared with the prior art, the beneficial effect of the present invention is that the accessories of the batcher are made of injection molded parts made of PP plastic material with 1%-4% ethylene added. Compared with steel materials, they are lighter in weight and have excellent acid and alkali corrosion resistance, and will not corrode in the long-term humid environment of the pig house. The collection bin and rotating bin between the automatic material line conveyor pipe and the precision bucket can control the automatic material line and precision feeding separately. During the operation of the automatic material line controlled by strong electricity, the materials fill the collection bin and the rotating bin, and then the strong electricity can be disconnected. The batcher controlled by the weak current DC reduction motor starts to work and adds the materials in the collection bin and the rotating bin to the precision bucket for precision feeding. Therefore, the strong electricity controlling the automatic material line will not affect the precision of the batcher adding to the precision bucket. The automatic material line conveyor pipe has multiple openings for material discharge at a collection bin feed inlet to avoid the phenomenon that the material forms a cone in the buffer bin due to a single opening, and the material at the opening has reached the highest point to block the discharge port while there is still little material around. The upper opening of the collection bin is widened and the middle is made into an enlarged cylindrical shape. The materials form multiple small cones in the collection bin, which complement the places where the materials are missing and increase the material filling capacity of the collection bin. The rotating bin can make the batcher rotate in multiple directions to select the feeding trough for pregnant sows, and the angle can reach 340 degrees. The connection between the rotating bin and the collection bin of the present invention is completed by sliding a plastic slider in a plastic slideway, avoiding the connection with iron bolts. It is easy to disassemble and will not be corroded and rusted by oil stains. The slideway is equipped with a limit block to limit the rotation angle of the batcher and control it within the range of 360 degrees. It can avoid the unlimited rotation of the batcher and cause the DC reduction motor wires to be entangled. There is a distance of 6 auger pitches from the center of the rotating bin discharge port to the direction of the DC reduction motor, leaving a certain space for the auger to reverse and return the material, and will not cause the reverse accumulation of materials.

DETAILED DESCRIPTION

[0011] The present invention is further described below in conjunction with the accompanying drawings: The multi-directional feeding and dispensing device for pregnant sows is composed of a one-way wheel assembly 1, a discharge port 2, an auger shaft 3, a DC reduction motor 5, a rotating bin 6, and a collection bin 12. The collection bin 12 is composed of a reducer 14 with a square upper section and a circular lower section and an inner cylinder 13, and the rectangular feed inlet of the collection bin 12 is butted against the opening of the feed pipe of the automatic feed line, and the rotating bin 6 is composed of an outer cylinder 8, a reducer 7 with a circular upper section and a square lower section, and a transverse feed pipe 4, and the rectangular discharge port of the rotating bin 6 is butted against the feed inlet of the transverse feed pipe 4. The outer surface of the inner cylinder 13 of the collecting bin 12 has an upper slide 11 and a lower slide 10 which are parallel to each other. The lower slide 10 has two openings of different sizes on both sides. The larger opening is the lower slide entrance 16, and the smaller opening is the upper slide lower entrance 20. The upper entrance 19 of the upper slide is located directly above the lower entrance 20 of the upper slide and is equal in size. There are limit blocks 18 on both sides of the upper entrance 19 of the upper slide. The lower slide 17 enters the lower slide 10 from the lower slide entrance 16, and the upper slide 9 enters the upper slide 11 from the vertically distributed lower entrance 20 of the upper slide and the lower entrance 19 of the upper slide. The two slides slide in a circle on the slide between the limit blocks 18 to complete the rotary motion of the batcher. The batcher can rotate in multiple directions to select the feeding trough for pregnant sows to feed, and the angle reaches 340 degrees. The lower connecting card 15 of the automatic feed line is fixed to the feeding pipe of the automatic feed line by bolt connection with the connecting card on the automatic feed line, and the DC reduction motor 5 is connected to the electrical control system through wires. The material collecting bin 12 with the automatic material line connecting card 15, the rotary bin 6, the transverse material conveying pipe 4, and the auger shaft 3 are all made of injection molded parts of PP plastic material with 1%-4% ethylene added.

[0012] When working, the rotating bin 6 is rotated to align the discharge port 2 with the trough of the pregnant sows that need to be fed. First, the strong electricity required for the operation of the automatic feed line conveying pipe is turned on, and the material is conveyed forward along the automatic feed line conveying pipe, and falls into the rotating bin 6 through the 5 openings of the automatic feed line conveying pipe. When the material evenly fills the collecting bin 12, the strong electricity is turned off to stop the material conveying work in the automatic feed line conveying pipe. Then the weak current DC reduction motor 5 is turned on, and the DC reduction motor 5 drives the auger shaft 3 to rotate forward, pushing the material forward. At this time, the one-way wheel assembly 1 does not rotate, and the sealing ball connected to the one-way wheel assembly 1 through the pull wire blocks the discharge port under the action of its own weight, and the material enters the precision bucket. When the material in the precision bucket reaches the weight set by the computer, the batcher stops feeding the precision bucket, and the DC reduction motor 5 drives the auger shaft 3 to rotate in the opposite direction. The one-way wheel assembly 1 reverses to drive the pull wire to wind and reel, and the sealing ball is lifted to realize material discharge. The remaining material in the horizontal feed pipe 4 is pushed back to the space between the center of the discharge port of the rotating bin 6 and the direction of the DC reduction motor 5.
