Description

Technical Field

[0001] This utility model relates to the technical field of automatic feed adding equipment for cattle sheds, and specifically to an automatic feed adding device for cattle sheds. Background Technology

[0002] With the increase in national income in my country, the demand for high-quality beef, as well as premium dairy products such as cheese, butter, and chilled milk, continues to grow. Small-scale farming, once prevalent, is rapidly exiting the market, while large-scale farming has become the dominant force. In large-scale cattle farming, cattle sheds are typically required. These sheds, also known as cowsheds, are specialized buildings that provide shelter, feeding, management, and production activities for cattle. Feed troughs are installed inside the sheds for adding feed. To ensure that a large number of cattle can eat simultaneously and to prevent fighting among them, which could negatively impact farming efficiency, cattle sheds are typically designed to be long and narrow.

[0003] Currently, existing feed troughs often require manual addition of feed at regular intervals and in measured quantities. This work is arduous and frequent, and problems such as uneven distribution and feed spillage are common, leading to feed waste. Furthermore, the long length of the feed troughs means that workers need to travel long distances and spend a lot of time adding feed, resulting in high labor intensity, high labor costs, low automation, and low feed addition efficiency, which cannot meet the needs of current cattle farming development. Therefore, developing an automatic feed addition device for cattle sheds that is highly efficient, provides good results, and has a high degree of automation is objectively necessary. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feed addition device for cattle sheds that is highly efficient, effective, and automated.

[0005] The purpose of this utility model is achieved as follows: it includes a hopper, a support frame, and a feed trough mounted on the support frame. A weighing sensor is installed at the bottom of the feed trough. A screw conveyor is connected to the bottom of the hopper. Several discharge pipes are spaced apart along the length of the bottom of the screw conveyor housing. A distribution hopper is installed below the screw conveyor. The lower end of the discharge pipes is connected to the top of the distribution hopper. A drop pipe and a guide pipe are connected sequentially to the bottom of the distribution hopper. The cross-sections of the distribution hopper, drop pipe, and guide pipe are all rectangular, and the length of the rectangle is parallel to the length of the feed trough. The lower end of the guide pipe is located above the feed trough. A semi-cylinder is installed on one side wall of the upper part of the drop pipe. A rotating shaft is concentrically installed inside the semi-cylinder. Two strip plates are symmetrically installed on the rotating shaft. The width of the strip plates is the same as the width of the drop pipe and the radius of the semi-cylinder.

[0006] Furthermore, a vibrator is installed on the feed guide tube.

[0007] Furthermore, the vibrator is equipped with a vibrating rod, the upper end of which extends upward into the material drop pipe below the semi-cylinder.

[0008] Furthermore, a spreading shaft parallel to its length is installed at the upper part of the fabric bin. A spreading plate is inclinedly installed on the spreading shaft below each feeding pipe. One end of the spreading shaft is equipped with an end plate, and the other end extends to the outside of the fabric bin. A telescopic rod and a spring are installed between the end plate and the side wall of the fabric bin. A spreading motor is installed on the outside of the fabric bin. A cam is installed on the output shaft of the spreading motor, and the end of the spreading shaft abuts against the cam.

[0009] Furthermore, a roller is provided at the end of the spreading shaft, and the roller abuts against the cam.

[0010] Furthermore, multiple material distribution plates are spaced apart on the top and bottom of the material distribution plate, and the material distribution plates are in an inverted V shape.

[0011] Furthermore, a dispersing shaft is installed at the top of the fabric bin, and multiple dispersing plates are evenly distributed around the circumference of the dispersing shaft. The length direction of the dispersing plates is arranged along the axial direction of the dispersing shaft. One end of the dispersing shaft is rotatably connected to the fabric bin, and the other end is driven to a dispersing motor.

[0012] Furthermore, a baffle is provided at the bottom of the lower end of the feed guide tube, and the lower end of the baffle extends into the feed trough.

[0013] This utility model is installed in a cattle shed for automatic feed addition. During operation, the screw conveyor is started first, and the feed in the hopper falls into the screw conveyor. Then, under the conveyor's transport, the feed is discharged from various discharge pipes. When the feed falls into the distribution hopper, due to the multiple drop points, the feed is evenly distributed within the hopper. When feed needs to be added, the existing drive device rotates the shaft, positioning two strip plates above and below the shaft, making them vertically arranged. At this time, the discharge pipe is unobstructed, and the feed in the distribution hopper can sequentially fall into the feed trough through the discharge pipe and the guide pipe. A weighing sensor detects the amount of feed added. When the added amount reaches a predetermined value, the shaft is rotated 90°, making the two strip plates horizontally arranged. The two strip plates block the discharge pipe and the discharge channel in the semi-cylinder, thus stopping the feeding. In this invention, feed addition in the cattle shed is automated. The amount of feed added to the feed trough is monitored by a weighing sensor, allowing for precise control of the feed addition amount. This effectively fulfills the need for timed and quantitative feed addition, eliminating the need for manual intervention and achieving a high degree of automation, thus significantly improving feed addition efficiency. Secondly, the feed distribution bin, feed drop pipe, and feed guide pipe in this invention all have rectangular cross-sections, with the length of the rectangle parallel to the length of the feed trough. When feed falls, it falls simultaneously and is evenly distributed throughout the feed trough, further enhancing feed addition efficiency. The results are better. Compared with traditional manual feed addition methods, the feed addition speed is significantly improved, and feed can be added in a shorter time, reducing labor intensity and labor costs. Furthermore, during feed addition, the feed enters from the hopper via a screw conveyor, then into the distribution hopper, and then sequentially falls into the feed trough through the discharge pipe and the guide pipe. Throughout the process, the feed is in a relatively sealed environment, preventing contamination. The feed is directly guided into the feed trough through the guide pipe, preventing feed from falling to the ground and avoiding waste. This effectively meets the current needs of cattle farming. In summary, this invention has the advantages of high efficiency, good addition effect, and high degree of automation. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the present invention shall fall within the protection scope of the present invention.

[0016] like Figures 1-4 As shown, this utility model includes a hopper 1, a support 2, and a feed trough 3 mounted on the support 2. A weighing sensor 4 is installed at the bottom of the feed trough 3. The weighing sensor 4 is an existing instrument used to detect the total weight of the feed trough 3 and the feed inside it. The weight of the feed trough 3 is fixed, and the total weight minus the weight of the feed trough 3 is the amount of feed added. This utility model is used to detect the amount of feed added. A screw conveyor 5 is connected to the bottom of the hopper 1. Several discharge pipes are spaced along the length of the bottom of the screw conveyor 5. A distribution hopper 6 is installed below the screw conveyor 5. In use, the feed is spread evenly in the distribution hopper 6 and then falls evenly from the discharge pipe 7 and the guide pipe 8. The lower end of the discharge pipe is connected to the top of the distribution hopper 6. The bottom of the distribution hopper 6 is connected to the discharge pipe 7 and the guide pipe 8 in sequence. All pipes 8 have rectangular cross-sections, with the length of the rectangle parallel to the length of the feed trough 3. The lower end of the guide pipe 8 is located above one side of the feed trough 3. A semi-cylinder 9 is installed on the side wall of the upper part of the feed pipe 7. A rotating shaft 10 is concentrically installed inside the semi-cylinder 9. Two strip plates 11 are symmetrically arranged on the rotating shaft 10. The width of the strip plates 11 is the same as the width of the feed pipe 7 and the radius of the semi-cylinder 9. When the two strip plates 11 are arranged horizontally, they can block the feed from falling into the feed pipe 7. When the two strip plates 11 are arranged vertically, the feed pipe 7 is in a completely unobstructed state, and the feed can fall smoothly. Similarly, if the two strip plates 11 are in a certain inclined state, they are in a partially unobstructed state. In short, by adjusting the rotation angle of the two strip plates 11 to make them in horizontal, vertical, and inclined states, the amount of feed falling can be adjusted and controlled.

[0017] This utility model is installed in a cattle shed for automatic feed addition. During operation, the screw conveyor 5 is started first, and the feed in the hopper falls into the screw conveyor 5. Then, under the conveyor 5, the feed is discharged from various discharge pipes. When the feed falls into the distribution bin 6, due to the multiple drop points, the feed is evenly distributed within the distribution bin 6. When feed needs to be added, the existing drive device rotates the shaft 10, causing the two strip plates 11 to be positioned... The two strip plates 11 are arranged vertically above and below the rotating shaft 10. At this time, the feed pipe 7 is unobstructed, and the feed in the feed bin 6 can fall into the feed trough 3 in sequence through the feed pipe 7 and the guide pipe 8. The weighing sensor 4 detects the amount of feed added. When the amount added reaches the predetermined value, the rotating shaft 10 is rotated by 90°, so that the two strip plates 11 are arranged horizontally. The two strip plates 11 block the feed pipe 7 and the feed channel in the semi-cylinder 9 respectively, and the feeding can be stopped.

[0018] In this invention, the addition of feed in the cattle shed is automated. The amount of feed added to the feed trough 3 is monitored by a weighing sensor 4, which allows for precise control of the feed addition amount and effectively fulfills the need for timed and quantitative feed addition. The entire process requires no manual intervention, exhibiting a high degree of automation and significantly improving the efficiency of feed addition. Furthermore, the feed distribution bin 6, the feed drop pipe 7, and the guide pipe 8 in this invention all have rectangular cross-sections, with the length of the rectangle parallel to the length of the feed trough 3. When the feed falls, it falls simultaneously and is evenly distributed throughout the feed trough 3, enhancing the feed addition effect. Compared to the traditional method of manually adding feed, the feed addition speed is significantly increased, allowing for feed addition to be completed in a shorter time, thus reducing labor intensity and labor costs. In addition, during feed addition, the feed enters from the hopper 1 into the screw conveyor 5, then into the distribution hopper 6, and then falls sequentially through the drop pipe 7 and the guide pipe 8 into the feed trough 3. Throughout the process, the feed is in a relatively sealed environment and will not be contaminated. Furthermore, the feed is directly guided into the feed trough 3 through the guide pipe 8, preventing feed from falling to the ground and avoiding feed waste. This method can better meet the current development needs of cattle farming.

[0019] A vibrator 12 is installed on the inclined feed guide pipe 8. The vibrator 12 is an existing feature that generates vibration, which is transmitted to the inclined feed guide pipe 8, the feed drop pipe 7, and the feed distribution bin 6 to prevent feed blockage and ensure smooth feed flow. A vibrating rod 13 is installed on the vibrator 12. The upper end of the vibrating rod 13 extends upwards into the feed drop pipe 7 below the semi-cylinder 9. The vibration from the vibrator 12 is transmitted to the vibrating rod 13, which is located inside the feed drop pipe 7. When the vibrating rod 13 vibrates, it clears the surrounding feed, ensuring smooth feed flow and clearing blockages. The number of vibrators 12 and vibrating rods 13 can be determined according to actual conditions.

[0020] A spreading shaft 14 parallel to its length is installed at the upper part of the feeding bin 6. A spreading plate 15 is inclinedly installed on the spreading shaft 14 below each feeding pipe. One end of the spreading shaft 14 is provided with an end plate, and the other end extends to the outside of the feeding bin 6. A telescopic rod and a spring 16 are provided between the end plate and the side wall of the feeding bin 6. A spreading motor is installed on the outside of the feeding bin 6. A cam 17 is provided on the output shaft of the spreading motor. The end of the spreading shaft 14 abuts against the cam 17. The spreading motor is an existing drive device. When running, the spreading shaft 14 always abuts against the cam 17 under the action of the spring 16. When the spreading motor drives the cam 17 to rotate, it will force the spreading shaft 14 to move back and forth in the horizontal direction, thereby driving the spreading plate 15 to move back and forth laterally, so that the feed is distributed more evenly after falling.

[0021] The end of the spreading shaft 14 is provided with a roller 18, which abuts against the cam 17. The end of the spreading shaft 14 abuts against the cam 17. The two are in rigid contact and have hard friction, which may cause problems such as running jamming and sluggishness. To solve this problem, the roller 18 is provided. Rolling friction replaces sliding friction, which greatly reduces friction and makes the operation smoother.

[0022] Multiple feed distribution plates 19 are arranged at intervals on the feed distribution plate 15. The feed distribution plates 19 are inverted V-shapes. When the feed falls onto the feed distribution plate 15, the feed will roll from the higher end to the lower end because the feed distribution plate 15 is inclined. During the rolling process, the feed will be dispersed on the entire feed distribution plate 15 under the action of the feed distribution plates 19, so that the feed falls more evenly into the feed distribution bin 6.

[0023] A dispersing shaft 20 is installed at the top of the feed hopper 6. Multiple dispersing plates 21 are evenly distributed around the circumference of the dispersing shaft 20. The length direction of the dispersing plates 21 is arranged along the axial direction of the dispersing shaft 20. One end of the dispersing shaft 20 is rotatably connected to the feed hopper 6, and the other end is driven to a dispersing motor. The dispersing motor is an existing drive device. When running, the dispersing motor drives the dispersing shaft 20 to rotate, and the dispersing shaft 20 drives the dispersing plates 21 to rotate. When the feed falls from the feed pipe, it will fall to the position of the dispersing shaft 20. During the rotation, the dispersing plates 21 collide with the feed, thereby breaking up the sticky feed. At the same time, the feed is more dispersed, the falling points are more dispersed, and the accumulation is more flat.

[0024] A baffle 22 is installed at the bottom of the lower end of the feed guide pipe 8. The lower end of the baffle 22 extends into the feed trough 3. The feed guide pipe 8 is located above one side of the feed trough 3. Feed falls from the feed guide pipe 8 into the feed trough 3. Because there is a certain gap between the feed guide pipe 8 and the feed trough 3, a small amount of feed may fall through this gap during the feed falling and during the cattle's feeding process, resulting in feed waste. Therefore, the baffle 22 is installed to block the gap and prevent feed from falling out and being wasted. In actual use, to prevent the feed guide pipe 8 from blocking the cattle from eating the feed, it will be placed on one side. It is only necessary to ensure that all the feed falls into the feed trough 3. At this time, the feed will fall more easily. Outside the feed trough 3, the height of the guide pipe 8 can be appropriately lowered to reduce or even eliminate the gap. Alternatively, a baffle 22 can be installed to block the gap and prevent feed from falling. In addition, since the feed pipe 7 and the guide pipe 8 are usually suspended, they may deform or tilt over time, causing the lower end of the guide pipe 8 to move outward from the feed trough 3, preventing the feed from falling completely into the feed trough 3. The baffle 22 extends into the feed trough 3 to position and constrain the guide pipe 8, preventing it from moving laterally. If necessary, the baffle 22 can be pressed tightly against the feed trough 3 or even fixed to it to minimize the space occupied by the feed trough 3.
