Description

Technical Field

[0001] The present invention relates to the field of blanking devices for feeding systems, and specifically to an automatic blanking device for a feeding system applied to the livestock breeding industry. Background Art

[0002] A common method for transporting feed in the livestock breeding industry is to use an aerial feed conveyor line to transport feed. The feed is transported from the storage bin to the farm through pipelines, and the feed can also be input into the feed storage bin or transferred between various feed storage bins using pipelines.

[0003] The conveyor line of the existing feed feeding system is provided with a blanking control device above each storage bin. Most of the existing blanking control devices use an electric push rod to control the sliding of the plug board, and the area of the plug board blocking the blanking port is used to control the blanking speed.

[0004] However, when the electric push rod or the control circuit inside the device of the existing automatic blanking device is damaged, or in the event of a power outage or other emergencies, effective control measures are often unable to be taken to control the plug board, and it is easy for the feed to continuously fall into the storage bin uncontrollably, resulting in the storage volume in the storage bin exceeding the planned capacity. In the face of such emergencies, the usual approach is to suspend the feed conveyor line, climb to the top of the feed storage bin to repair the automatic blanking device, and then restart the feed conveyor line.

[0005] Therefore, when an emergency occurs in the existing automatic blanking device of the feed feeding system in the livestock breeding industry and it is unable to continue normal operation, it is not easy to quickly control the position of the plug board at the blanking port. Summary of the Invention

[0006] Based on this, the purpose of the present invention is to provide an automatic blanking device for a feeding system applied to the livestock breeding industry, so as to solve the technical problem that when an emergency occurs in the existing automatic blanking device of the feed feeding system in the livestock breeding industry and it is unable to continue normal operation, it is not easy to quickly control the position of the plug board at the blanking port.

[0007] To achieve the above object, the present invention provides the following technical solution: An automatic blanking device for a feeding system applied to the livestock breeding industry, including an insertion plate table, in which an insertion plate slides, an electric push rod is arranged on one side of the insertion plate table, a guiding ring is arranged at one end of the insertion plate table, and a first fixed pulley is arranged at the other end. One corner of the insertion plate extends out of the insertion plate table and is connected with a sliding box. The sliding box is in a concave shape, and a first through hole and a second through hole are respectively arranged on both sides. A connecting block is rotatably arranged at the bottom of the sliding box. The front end of the electric push rod is fixedly connected with a concave connecting table, and the opening of the concave is facing the sliding box. The cross section of the connecting block is trapezoidal in reverse, and is stuck on the connecting table. Two telescopic columns are connected to the connecting block, and ropes are connected to both telescopic columns. One rope passes through the second through hole and then through the guiding ring, and the other rope passes through the first through hole, then bypasses the first fixed pulley and finally passes through the guiding ring.

[0008] By adopting the above technical solution, by arranging a connecting block at the connection between the insertion plate of the automatic blanking device and the front end of the electric push rod, in the event of sudden situations such as damage to the electric push rod, a long stick can be used to push open the lid of the rope box, and then the staff standing on the ground can pull the insertion plate to slide through the rope, adjust the position of the insertion plate, and thus conveniently manually control the position of the insertion plate in case of emergencies without pausing the feed conveying line, improving the reliability of the automatic blanking device.

[0009] The present invention is further arranged such that two vertical telescopic columns are connected to the connecting block, a second fixed pulley is arranged inside the connecting block below the telescopic columns, both sides of the bottom end of the connecting block are slidably connected with sliding blocks, a pulling rope bypassing the second fixed pulley is connected between one end of the sliding block and the bottom end of the telescopic column, reset springs are arranged for both the telescopic column and the sliding block inside the connecting block, and when the telescopic column rises, the sliding block slides into the inside of the connecting block.

[0010] By adopting the above technical solution, since the cross section of the connecting block is trapezoidal in reverse, it cannot continue to rotate downward after being placed on the connecting table, and the sliding block extending out of the connecting block can well limit the upward rotation of the connecting block. Therefore, when the electric push rod is working normally, the connecting block can be effectively prevented from detaching from the connecting table. When the lid of the rope box is opened and the rope is pulled, the telescopic column pulled upward pulls the sliding block back into the inside of the connecting block through the pulling rope inside the connecting block, and thus while rotating and pulling up the connecting block, the locking of the connecting block by the sliding block is released.

[0011] The present invention is further arranged such that a rope box is arranged at one end of the insertion plate table close to the guiding ring, a lid is rotatably arranged at the bottom end of the rope box, and the rotating shaft of the lid is arranged at one end of the bottom of the rope box close to the guiding ring.

[0012] By adopting the above technical solution, the rope box is used to accommodate a rope of sufficient length so that the staff can freely pull the two ropes even when standing on the ground.

[0013] The present invention is further configured such that a vertical partition is provided in the middle of the rope box. After the two ropes passing through the guide ring pass through the gap between the rotating shaft of the box cover and the rope box, they are respectively wound around both sides of the partition in the rope box.

[0014] By adopting the above technical solution, the partition can effectively prevent the two ropes in the rope box from being entangled with each other, so that when the box cover is opened instantaneously, the two ropes inside the rope box can quickly fall.

[0015] The present invention is further configured such that when the box cover is closed, the gap between the rope box and the rotating shaft of the box cover is smaller than the diameter of the rope, and when the box cover is opened, the gap between the rope box and the rotating shaft of the box cover is larger than the diameter of the rope.

[0016] By adopting the above technical solution, when the box cover is closed, the rope can be clamped by squeezing the rope, so as to prevent the rope from being pulled out of the rope box when the box cover is not opened. At the same time, when the box cover is in the open state, the clamping of the rope will be automatically released.

[0017] The present invention is further configured such that a locking box is provided at one end of the rope box away from the rotating shaft of the box cover. A locking tongue inserted into the locking box is fixedly provided on the box cover. A perforation is provided on the locking tongue. The perforation on the locking tongue corresponds to the perforation provided in the locking box. A glass column is inserted into the perforation in the locking box. A blade for breaking the glass column is provided on the bottom wall of the locking tongue at the perforation towards the glass column.

[0018] By adopting the above technical solution, in the case of a power failure or all the electrical circuits in the device being damaged, a long rod can be used to forcefully push up the box cover. At the moment when the box cover is pushed up, the blade on the locking tongue will cut off the glass column, thereby releasing the limit of the glass column on the box cover, so that the ropes inside the rope box can fall freely for the staff to use.

[0019] The present invention is further configured such that an easily evaporable liquid is accommodated in the glass column, and a conductive head is provided at one end. The conductive head at one end of the glass column is connected to an electric heating wire inside the glass column. A remote control power-on switch connected to the conductive head on the glass column is provided in the locking box.

[0020] By adopting the above technical solution, when the remote control power switch in the locking box is not damaged, there is no need to look for a long rod. Only need to remotely control the power supply to the conductive head at one end of the glass column through the remote control, so that the heating wire inside the glass column generates heat, quickly evaporates the easily evaporable liquid inside the glass column, the pressure inside the glass column instantaneously increases, quickly breaks the glass column, and the broken glass column can no longer restrict the box cover, and the box cover can be conveniently flipped open. Compared with the method of using a long rod to push open the box cover, this is faster, but it is necessary to ensure that the remote control power switch in the locking box can still work, and the reliability is inferior to the method of using a long rod to push open the box cover.

[0021] The present invention is further configured such that one end of the plug board table is fixedly connected with a guide rail, the guide rail continues the plug board sliding track in the plug board table, two mutually parallel sliding rods are arranged in the plug board table along the sliding direction of the plug board below the plug board, one end of the plug board away from the guide rail is fixedly connected with a slider, and the slider is slidably connected to the sliding rod.

[0022] By adopting the above technical solution, the slider connected to the bottom end of the plug board is slidably connected to the sliding rod, which can play a role in supporting the edge of the plug board, avoiding the feed sliding down from deforming the plug board, and thus effectively avoiding the plug board from not being able to slide smoothly.

[0023] In summary, the present invention mainly has the following beneficial effects:

[0024] The present invention is provided with a connection block at the connection between the plug board of the automatic feeding device and the front end of the electric push rod. When a sudden situation such as the damage of the electric push rod occurs, the box cover of the rope box can be pushed open with a long stick, and then the staff can stand on the ground and pull the plug board to slide through the rope, adjust the position of the plug board, and thus conveniently manually control the position of the plug board in case of a sudden situation without pausing the feed conveyor line, improving the reliability of the automatic feeding device;

[0025] The present invention is provided with a connection block with an inverted trapezoidal cross-section, and at the same time, a connection platform for cooperating with the connection block is connected to the front end of the electric push rod, so that the connection block can be conveniently placed on the connection platform. At the same time, a horizontally sliding slider is arranged at the bottom end inside the connection block, and the connection block is locked by using the slider to ensure the stable connection between the connection block and the connection platform during the operation of the device. When a sudden situation occurs and it is necessary to control the plug board through the rope, the pulling of the rope causes the slider to retract into the connection block, quickly unlocking the locking of the connection block, so that the connection block can be smoothly turned upwards and separated from the connection platform, and thus will not be restricted by the connection platform during movement;

[0026] In the present invention, the lid of the rope box is arranged at the bottom of the rope box, and the rotating shaft of the lid is arranged on the side close to the plug board. The rope is passed through the space between the rotating shaft of the lid and the rope box. Since the thickness of the lid at the rotating shaft is inconsistent, the rope can be clamped by the lid in the closed state, preventing the rope in the rope box from being pulled out when the plug board moves normally. When the lid is in the open state, the clamping of the rope will be released, allowing the rope to be pulled freely;

[0027] In the present invention, a hollow glass column containing an easily evaporable liquid is used to limit the rotation of the lid. When it is necessary to open the lid, the electric heating wire in the hollow glass column can be energized to quickly evaporate the easily evaporable liquid in the hollow glass column, causing the air pressure in the hollow glass column to rapidly increase and burst, thereby releasing the limit on the lid and quickly releasing the rope in the rope box, saving the time to find a long stick and opening the lid more quickly.

Embodiment

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0040] The embodiments of the present invention will be described below according to its overall structure.

[0041] An automatic blanking device for a feeding system applied to the livestock breeding industry, as Figure 1-10As shown in the figure, it includes a plug board table 1. A discharge pipe 24 is connected below the plug board table 1, and a pipe sleeve 25 is connected above. A feeding pipe 23 passes through the pipe sleeve 25. The feeding pipe 23 has a downward opening at the pipe sleeve 25. After the feed passes through the feeding pipe 23, it flows downward from the opening at the pipe sleeve 25, slides downward after passing through the plug 2 of the plug board table 1, and finally flows into the storage tank through the discharge pipe 24. And in order to better protect the automatic feeding device, a protective cover 27 is provided at the plug board table 1 for the feeding pipe 23. A plug 2 slides in the plug board table 1. Specifically, a track for the plug 2 to slide is provided in the plug board table 1 to prevent the feed from flowing downward through the gap between the plug 2 and the plug board table 1. An electric push rod 5 is provided on one side of the plug board table 1. Specifically, controlling the movement of the plug 2 by the electric push rod 5 is an existing technology. A guide ring 26 is provided at one end of the plug board table 1, and a first fixed pulley 10 is provided at the other end. The guide ring 26 is used to guide the rope 20 so that it can face the gap between the box cover 16 and the rope box 15. A corner of the plug 2 extends out of the plug board table 1 and is connected to a sliding box 7. The sliding box 7 is concave-shaped, and a first through hole 8 and a second through hole 9 are respectively provided on both sides. A connecting block 11 is rotatably provided at the bottom of the sliding box 7. The front end of the electric push rod 5 is fixedly connected to a concave-shaped connecting platform 6, and the notch faces the sliding box 7. The cross-section of the connecting block 11 is trapezoidal in reverse, and it is stuck on the connecting platform 6. Two telescopic columns 12 are connected to the connecting block 11. Both of the two telescopic columns 12 are connected to a rope 20. One of the ropes 20 passes through the second through hole 9 and then through the guide ring 26, and the other rope 20 passes through the first through hole 8, then bypasses the first fixed pulley 10 and finally passes through the guide ring 26. Specifically, when the rope 20 bypassing the first fixed pulley 10 is pulled, the plug 2 slides towards the first fixed pulley 10, and when the other rope 20 is pulled, the plug 2 slides towards the guide ring 26. Two vertical telescopic columns 12 are connected to the connecting block 11. A second fixed pulley 13 is provided below the telescopic columns 12 inside the connecting block 11. Both sides of the bottom end of the connecting block 11 are slidably connected to sliding blocks 14. A pulling rope bypassing the second fixed pulley 13 is connected between one end of the sliding block 14 and the bottom end of the telescopic column 12. Return springs are provided for the telescopic columns 12 and the sliding blocks 14 inside the connecting block 11. When the telescopic column 12 rises, the sliding block 14 slides into the connecting block 11. Since the cross-section of the connecting block 11 is trapezoidal in reverse, it cannot continue to rotate downward after being placed on the connecting platform 6, and the sliding block 14 extending out of the connecting block 11 can well limit the upward rotation of the connecting block 11. Therefore, when the electric push rod 5 works normally, the connecting block 11 can be effectively prevented from detaching from the connecting platform 6. And when the box cover 16 of the rope box 15 is opened and the rope 20 is pulled, the telescopic column 12 pulled upward pulls the sliding block 14 back into the connecting block 11 through the pulling rope inside the connecting block 11. Then, while rotating and pulling up the connecting block 11, the locking of the connecting block 11 by the sliding block 14 is released.

[0042] Please refer to Figure 4 and Figure 8 As shown in, at one end of the plug board table 1 close to the guide ring 26, a rope box 15 is provided. A box cover 16 is rotatably arranged at the bottom end of the rope box 15. The rotating shaft of the box cover 16 is arranged at one end of the bottom of the rope box 15 close to the guide ring 26. The rope box 15 is used to accommodate a rope 20 of sufficient length. The specific length of the rope 20 of sufficient length is determined according to the height of the storage tank where the automatic blanking device is installed, so that the staff can freely pull the two ropes 20 while standing on the ground. A vertical partition 19 is arranged in the middle of the rope box 15. The partition 19 can effectively prevent the two ropes 20 in the rope box 15 from being wound around each other, so that when the box cover 16 is opened, the two ropes 20 inside the rope box 15 can quickly fall. After the two ropes 20 passing through the guide ring 26 pass through the gap between the rotating shaft of the box cover 16 and the rope box 15, they are respectively coiled on both sides of the partition 19 in the rope box 15. When the box cover 16 is closed, the gap between the rope box 15 and the rotating shaft of the box cover 16 is smaller than the diameter of the rope 20. When the box cover 16 is opened, the gap between the rope box 15 and the rotating shaft of the box cover 16 is larger than the diameter of the rope 20. Specifically, the thickness at the rotating shaft of the box cover 16 is not uniform, so that when the box cover 16 is closed, the rope 20 can be clamped by squeezing the rope 20, preventing the rope 20 from being pulled out of the rope box 15 when the box cover 16 is not opened. At the same time, when the box cover 16 is in the open state, the clamping of the rope 20 will be automatically released. Specifically, in order to enable the plug board 2 of the automatic blanking device to slide freely under the control of the electric push rod 5 in the normal state, when the box cover 16 clamps the rope 20 in the closed state, enough rope 20 is reserved for the plug board 2 to slide without being tightened.

[0043] Please refer to Figure 5 and Figure 6 As shown in, a guide rail 22 is fixedly connected to one end of the plug board table 1. The guide rail 22 continues the sliding track of the plug board 2 in the plug board table 1. Inside the plug board table 1, two parallel slide bars 3 are arranged along the sliding direction of the plug board 2 below the plug board 2. A slider 4 is fixedly connected to the bottom end of the side of the plug board 2 away from the guide rail 22. The slider 4 slides on the slide bar 3. The slider 4 connected to the bottom end of the plug board 2 slides on the slide bar 3, which can play a role in supporting the edge of the plug board 2, preventing the falling feed from deforming the plug board 2, and thus effectively preventing the plug board 2 from not being able to slide smoothly. If the plug board 2 is deformed, it is also easy to get out of the track, causing unnecessary trouble.

[0044] Please refer to Figure 8 and Figure 9, at one end of the rope box 15 away from the rotating shaft of the box cover 16, a locking box 17 is provided. A locking tongue 18 inserted into the locking box 17 is fixedly provided on the box cover 16. A perforation is provided on the locking tongue 18, and the perforation on the locking tongue 18 corresponds to the perforation provided in the locking box 17. A glass column 21 is inserted into the perforation in the locking box 17. A blade for breaking the glass column 21 is provided on the bottom wall of the locking tongue 18 at the perforation. In the case of a power outage or all electrical circuits in the device being damaged, a long rod can be used to forcefully push the box cover 16 upwards. At the moment when the box cover 16 is pushed upwards, the blade on the locking tongue 18 will cut off the glass column 21, thereby releasing the limit of the glass column 21 on the box cover 16, enabling the rope 20 inside the rope box 15 to freely fall for the staff to use. An easily evaporable liquid is contained in the glass column 21, and a conductive head is provided at one end. The conductive head at one end of the glass column 21 is connected to an electric heating wire inside the glass column 21. A remote control power-on switch connected to the conductive head on the glass column 21 is provided in the locking box 17. When the remote control power-on switch in the locking box 17 is not damaged, there is no need to look for a long rod. Only by remotely controlling the power supply to the conductive head at one end of the glass column 21 through a remote control, the heating wire inside the glass column 21 generates heat, quickly evaporating the easily evaporable liquid inside the glass column 21. The pressure inside the glass column 21 instantaneously increases, quickly bursting the glass column 21. Specifically, the quickly evaporating liquid is alcohol. The broken glass column 21 can no longer limit the box cover 16, and the box cover 16 can be conveniently flipped open. Compared with the method of using a long rod to push open the box cover 16, this is faster, but it is necessary to ensure that the remote control power-on switch in the locking box 17 can still work, and the reliability is inferior to the method of using a long rod to push open the box cover 16.

[0045] The working principle of the present invention is as follows: When a failure occurs in the blanking device and the remote control power-on switch in the locking box 17 is still usable, power is supplied to the end of the glass column 21 through the remote control power-on switch, so that the heating wire inside the glass column 21 heats the easily evaporable liquid inside it. The pressure inside the glass column 21 instantaneously increases and it is burst, the lid 16 is released from the limit and rotates downward under its own gravity to open. The rope 20 in the rope box 15 falls, and the inertia of the falling rope pulls the remaining rope 20, straightening the rope 20. At the same time, the locking structure at the connecting block 11 is unlocked and the connecting block 11 is lifted from the connecting platform 6, so that the connecting block 11 is separated from the connecting platform 6. The staff can respectively pull the two ropes 20 to smoothly slide the plug board 2. Specifically, when pulling the rope 20 passing through the first through hole 8, the plug board 2 slides towards the direction of the first fixed pulley 10, and when pulling the rope 20 passing through the second through hole 9, the plug board 2 slides towards the direction of the guide ring 26. When a failure occurs in the blanking device and the remote control power-on switch in the locking box 17 also fails, a long rod can be used to lift the lid 16, and the blade edge of the locking tongue 18 on the lid 16 cuts the glass column 21. The lid 16 can also be turned downward under its own gravity, improving the reliability of the manual control plug board 2 structure when the blanking device is damaged.

[0046] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and are not limitations on the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
