Description

Technical Field

[0001] The invention relates to the technical field of feed feeding, in particular to an adjustable feeding device. Background Art

[0002] Feeding of livestock feed refers to a technology that meets the growth and production needs of livestock through the reasonable delivery of feed. It is a key link in farm management and directly affects the growth rate, health status, production efficiency and product quality of livestock.

[0003] After searching, the Chinese patent with publication number CN102715097A discloses an animal feeding trough for feeding animals, comprising an inner wall and an outer wall of the trough and a trough center axis arranged therebetween, which is located on the wall of the pen; a trough center axis rotating wheel is arranged on the trough center axis, an inner wall of the trough is arranged on the inner wall of the trough, an outer wall of the trough is arranged on the outer wall of the trough, and a rotating fixing bolt is arranged on the wall of the pen. When the above technical solution is applied to the animal feeding trough, the animal feeding trough is rotated toward the outside of the pen wall by pressure, so that the rotating fixing bolt fixes the inner wall of the trough to ensure that the food is safely and conveniently put into the trough; and then the animal feeding trough is lifted and rotated toward the inside of the pen wall, so that the rotating fixing bolt fixes the outer wall of the trough to ensure that the animal eats safely and fully. However, the above solution still has the following shortcomings when it is actually used:

[0060] The present invention has the following beneficial effects:

[0061] 1. The advantage of this feed adding design is that it realizes the automatic cleaning function of the feed trough without manual operation. The motor drives the linear slide to drive the feeding hopper to move, which can not only complete the feeding of feed, but also during the movement, the fixed frame and the connected cleaning plate can push and clean the residual feed in the feed trough to prevent the new feed from mixing with the residual feed. This not only improves the accuracy and efficiency of feed feeding, but also reduces the tediousness and cost of manual cleaning, ensuring the quality and hygiene of feed;

[0062] 2. The linear slide rail controls the reset movement of the linear slide, which not only realizes the reciprocating operation of the hopper, but also cleverly uses this movement process to activate the feed conveying system. When the hopper moves toward the N end of the trough, the meshing of the second gear and the second rack drives the rotation of the transmission shaft and the bevel gear, which in turn drives the roller shaft to rotate, so that the feeding belt starts to operate. This series of mechanical linkages does not require an additional power source, realizing the effective use of energy and the self-driving of the system. Secondly, the rotation of the feeding belt discharges the feed from the accumulation through the discharge port, and accurately falls into the trough with the help of the inclined discharge plate. The whole process has a high degree of automation, ensuring the uniform and continuous addition of feed, and improving the accuracy and efficiency of feed feeding. In addition, this design also reduces manual intervention, reduces labor intensity, and improves the safety and hygiene standards of the overall operation;

[0063] 3. The cooperation between the guide cylinder and the guide rod on the mounting frame, supplemented by the friction between the first damping ring and the second damping ring, brings significant benefits. First, the setting of the guide cylinder and the guide rod effectively limits the moving path of the mounting frame, ensures its stability and accuracy during movement, and avoids deviation or shaking, which is crucial for the accuracy of feed addition and the reliability of the system. Secondly, the mutual friction between the first damping ring and the second damping ring generates a sufficiently large resistance, so that the mounting frame can firmly maintain its position when not affected by external forces, avoiding accidental movement caused by vibration, external force interference and other factors, and further enhancing the stability and safety of the system.

DETAILED DESCRIPTION

[0076] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0077] Reference Figure 1-11 , an adjustable feeding device, comprising: a trough 1, a collecting container 13 is arranged just below one end of the trough 1; a feeding hopper 2 is placed above the trough 1, and an inclined discharge plate is arranged on the feeding hopper 2, and the discharge plate is arranged just opposite to the discharge port of the feeding hopper 2; a fixing frame 3 is fixed on the side of the feeding hopper 2; a linear slide rail 4 is installed on the side of the trough 1; a linear slide seat 5 is slidably assembled on the linear slide rail 4, and the linear slide seat 5 is fixedly connected to the feeding hopper 2. The staff starts the motor installed on the linear slide rail 4 to make the linear slide seat 5 move on the linear slide rail 4. The way in which the motor drives the linear slide seat 5 is a prior art and will not be described in detail here;

[0078] The adjustable feeding device also includes a cleaning structure, which is arranged inside the trough 1 and connected to the feeding hopper 2. The cleaning structure includes a cleaning plate 63. The cleaning structure also includes: a mounting frame 61, which is placed below the fixing frame 3 and has a U-shaped structure; a rotating shaft 62, which is rotatably mounted on the mounting frame 61, and a cleaning plate 63 is fixedly sleeved on the rotating shaft 62; a plurality of bristles 64, which are bonded to the bottom surface of the cleaning plate 63. When the feeding hopper 2 moves, it can drive the fixing frame 3 to move, and the cleaning plate 63 connected to the fixing frame 3 will also move accordingly. The cleaning plate 63 can push the residual feed in the trough 1 during the movement.

[0079] The adjustable feeding device also includes a rotating structure, which is arranged on the trough 1 and is used to control the cleaning plate 63 to rotate. The rotating structure includes: a first gear 71, which is fixedly sleeved on one end of the rotating shaft 62; two first connecting rods 72, which are respectively fixed at the two ends of the trough 1; two first racks 73, which are respectively fixed at the ends of the two first connecting rods 72 away from the trough 1. After the cleaning plate 63 moves out from the M end of the trough 1, the first gear 71 will mesh with the first rack 73 at the M end of the trough 1, which makes the first gear 71 rotate and drives the rotating shaft 62 to rotate. When the rotating shaft 62 rotates, it can drive the cleaning plate 63 to rotate. When the first gear 71 is separated from the first rack 73 at the M end of the trough 1, the first gear 71 can rotate 90°, and the cleaning plate 63 can rotate to a horizontal state.

[0080] The adjustable feeding device also includes a control structure, which is arranged on the trough 1 and is used to control the cleaning plate 63 to move up and down. The control structure includes: two second connecting rods 81, which are respectively fixed at the two ends of the trough 1; two control blocks 82, which are respectively fixed at the ends of the two first connecting rods 72 away from the trough 1, and the two control blocks 82 are both provided with inclined surfaces, and the inclined directions of the inclined surfaces of the two control blocks 82 are opposite;

[0081] The adjustable feeding device also includes two connecting structures, both of which are arranged on the fixed frame 3. The connecting structures include: a guide cylinder 91, which is fixed to the bottom surface of the fixed frame 3, and both ends of the guide cylinder 91 are open; a guide rod 92, which is slidably arranged in the guide cylinder 91, and the bottom end of the guide rod 92 extends to the outside of the guide cylinder 91 and is fixedly connected to the fixed frame 3; a plurality of first damping rings 93, which are fixedly sleeved on the guide rod 92; a plurality of second damping rings 94, which are fixed on the inner ring of the guide cylinder 91, and the first damping ring The first and second damping rings 93 and 94 are both made of rubber material. A plurality of second damping rings 94 are arranged on the inner ring of the guide cylinder 91, and a plurality of first damping rings 94 are arranged on the guide rod 92. Under the cooperation of the plurality of first damping rings 94 and the plurality of second damping rings 94, there is a sufficiently large friction force between the guide cylinder 91 and the guide rod 92. Under the action of the friction force, the position of the mounting frame 61 will be fixed, that is, the mounting frame 61 will not move without force, thereby ensuring the stability of the mounting frame 61.

[0082] The adjustable feeding device also includes a shielding structure, which is arranged on the feeding hopper 2, and the shielding structure includes: a lifting baffle 101, which is slidably arranged on the side of the feeding hopper 2 and is arranged opposite to the discharge port of the feeding hopper 2; a side plate 102, which is fixed to the side of the feeding hopper 2; a sealing cylinder 103, which is fixed to the top surface of the side plate 102, and the top of the sealing cylinder 103 is provided with a through hole; a sealing slide rod 104, which is sealingly slidably connected to the inner surface of the sealing cylinder 103, and the top of the sealing slide rod 104 extends to the outside of the sealing cylinder 103 through the through hole; a connecting frame 105, one end of which is fixedly connected to the lifting baffle 101, and the other end is fixedly connected to one end of the sealing slide rod 104 located outside the sealing cylinder 103; an air bag 106, one end of which is connected to the fixing frame 3, and the other end of which is connected to the mounting frame 61; an air guide tube 107, one end of which is connected to the air bag 106, and the other end of which is connected to the sealing cylinder 103. When the mounting frame 61 moves upward, the mounting frame 61 will squeeze the air bag 106. When the air bag 106 is squeezed, the gas inside it will enter the inside of the sealing cylinder 103 through the air guide tube 107. When the gas enters the inside of the sealing cylinder 103, the gas can push the sealing slide bar 104 to move upward. When the sealing slide plate 104 moves upward, it can drive the connecting frame 105 to move, which makes the lifting baffle 101 move upward. When the upper baffle 101 moves upward, it no longer blocks the discharge port of the feeding hopper 2;

[0083] The adjustable feeding device also includes a discharging structure, which is arranged on the feeding hopper 2 and is used for automatic discharging. The discharging structure includes: two rollers 111, which are rotatably mounted on the two ends of the feeding hopper 2; a feeding belt 112, and the two rollers 111 are connected to each other through the feeding belt 112; a bracket 113, which is fixed to the side of the feeding hopper 2; a transmission shaft 114, which is rotatably mounted on the bracket 113; two bevel gears 115, one of which is fixedly sleeved on one of the rollers 111, and the other is fixedly sleeved on the rotating shaft 114, and the two bevel gears 115 are meshed with each other; a second gear 116, which is fixedly sleeved on the rotating shaft 114; a second rack 117, which is arranged on the feeding hopper 2; The second gear 116 is arranged above the trough 1, and is directly opposite to the second gear 116. When the feeding hopper 2 moves toward the N end of the trough 1, the second gear 116 will mesh with the second rack 117, which makes the second gear 116 rotate. When the second gear 116 rotates, it can drive the transmission shaft 114 to rotate. When the transmission shaft 114 rotates, it can drive the corresponding roller 111 to rotate through two mutually meshing bevel gears 115. The rotating roller 111 cooperates with another roller 111 to drive the feeding belt 112 to rotate. When the feeding belt 112 rotates, the feed accumulated on the feeding belt 112 will be discharged through the discharge port and fall into the inside of the trough 1 along the inclined discharge plate, so as to realize the automatic addition of feed;

[0084] The adjustable feeding device also includes a transmission structure, which is arranged on the material trough 1 and the hopper 2, and the transmission structure includes: two mounting plates 121, both fixed to the bottom surface of the material trough 1; two outer cylinders 122, respectively fixed to the top surfaces of the two mounting plates 121; two inner rods 123, respectively movably inserted in the two outer cylinders 122, and the top ends of the two inner rods 123 extend to the outside of the corresponding outer cylinders 122 and are fixedly connected to the second rack 117; two third connecting rods 124, respectively fixed to the two ends of the second rack 117.

[0085] The specific working principle of the present invention is as follows:

[0086] like Figure 5 As shown, for ease of understanding and representation, one end of the trough 1 is defined as the N end, and the other end is defined as the M end. The collecting container 13 is placed below the M end of the trough 1. In the initial state, the hopper 2 is placed at the N end of the trough 1. When feed needs to be added to the trough 1, the staff first puts the feed into the hopper 2. A slidable lifting baffle 101 is provided on the hopper 2. When the hopper 2 is located at the N end of the trough 1, the lifting baffle 101 can block the discharge port of the hopper 2, and the feed cannot be discharged through the discharge port. In addition, the cleaning plate 63 is in a vertical state, and the bristles 64 on its bottom surface are in contact with the inner bottom surface of the trough 1.

[0087] When adding feed, the staff starts the motor installed on the linear slide rail 4 to move the linear slide seat 5 on the linear slide rail 4. The way in which the motor drives the linear slide seat 5 is the existing technology and will not be described in detail here. When the linear slide seat 5 moves, it can drive the feeding hopper 2 to move, so that the feeding hopper 2 moves from the N end to the M end of the trough 1. In this process, the second gear 116 will not contact the second rack 117, and the second gear 116 will not rotate. In addition, when the feeding hopper 2 moves, it can drive the fixing frame 3 to move, and the cleaning plate 63 connected to the fixing frame 3 will also move accordingly. During the movement, the cleaning plate 63 can push the residual feed in the trough 1 and push the feed to the M end of the trough 1. When the feeding hopper 2 moves to the M end of the trough 1, the residual feed in the trough 1 can be pushed out by the cleaning plate 63, so that the feed falls into the interior of the collecting container 13. This design can clean the residual feed in the trough 1 and avoid mixing between the newly added feed and the residual feed.

[0088] After the cleaning plate 63 moves out from the M end of the trough 1, the first gear 71 will mesh with the first rack 73 at the M end of the trough 1, which makes the first gear 71 rotate and drives the rotating shaft 62 to rotate. When the rotating shaft 62 rotates, it can drive the cleaning plate 63 to rotate. When the first gear 71 is separated from the first rack 73 at the M end of the trough 1, the first gear 71 can rotate 90°, and the cleaning plate 63 can be rotated to a horizontal state. Further, with the continued movement of the feeding hopper 2, the mounting frame 61 will contact the control block 82 at the M end of the trough 1, and slide along the inclined surface of the control block 82, so that the mounting frame 61 moves upward;

[0089] When the mounting frame 61 moves upward, the mounting frame 61 will squeeze the airbag 106. When the airbag 106 is squeezed, the gas inside it will enter the interior of the sealing tube 103 through the air guide tube 107. When the gas enters the interior of the sealing tube 103, the gas can push the sealing slide bar 104 to move upward. When the sealing slide plate 104 moves upward, it can drive the connecting frame 105 to move, which makes the lifting baffle 101 move upward. When the baffle 101 moves upward, it no longer blocks the discharge port of the feeding hopper 2. At the same time, when the mounting frame 61 moves upward, it can also push the third connecting rod 124 at the end of the trough 1M to move, so that the third connecting rod 124 drives the second rack 117 to move upward. When the second rack 117 moves upward, , the second gear 116 can mesh with the second rack 117 during the movement. It is worth noting that, during the movement of the mounting frame 61, the two guide cylinders 91 and the two guide rods 92 play a role in limiting the movement of the mounting frame 61. In addition, a plurality of second damping rings 94 are provided on the inner ring of the guide cylinder 91, and a plurality of first damping rings 94 are provided on the guide rod 92. Under the cooperation of the plurality of first damping rings 94 and the plurality of second damping rings 94, there is a sufficiently large friction force between the guide cylinder 91 and the guide rod 92. Under the action of the friction force, the position of the mounting frame 61 will be fixed, that is, the mounting frame 61 will not move without force, thereby ensuring the stability of the mounting frame 61.

[0090] Furthermore, the linear guide rail 4 controls the linear slide 5 to reset, so that the feeding hopper 2 moves from the M end of the trough 1 toward the N end of the trough 1. Since the second rack 117 is located opposite to the second gear 116, the second gear 116 will mesh with the second rack 117 during the movement of the feeding hopper 2 toward the N end of the trough 1, so that the second gear 116 rotates. When the second gear 116 rotates, it can drive the transmission shaft 114 to rotate. When the transmission shaft 114 rotates, it can drive the corresponding roller shaft 1 through the two mutually meshing bevel gears 115. 11 rotates, and the rotating roller 111 cooperates with another roller 111 to drive the feeding belt 112 to rotate. When the feeding belt 112 rotates, the feed accumulated on the feeding belt 112 will be discharged through the discharge port and fall into the inside of the trough 1 along the inclined discharge plate, thereby realizing automatic addition of feed. It is worth noting that in the process of the feeding hopper 2 moving from the M end to the N end, the cleaning plate 63 is in a horizontal state. This design can prevent the cleaning plate 63 from pushing the feed falling into the inside of the trough 1, thereby ensuring that the feed is evenly distributed inside the trough 1;

[0091] When the feeding hopper 2 moves to the N end of the trough 1 and the cleaning plate 63 moves out from the inside of the trough 1, the first gear 71 will mesh with the first rack 73 at the N end of the trough 1. At this time, the first gear 71 will rotate in the opposite direction, so that the cleaning plate 63 will rotate to a vertical state again, and the cleaning plate 63 will be automatically reset. This design facilitates the cleaning plate 63 to clean the residual feed in the trough 1 again. With the continued movement of the feeding hopper 2, the mounting frame 61 will contact the control block 82 at the N end of the trough 1 and move downward under the action of the inclined surface of the control block 82, which makes the mounting frame 61 move downward. When the mounting frame 61 moves downward, it can stretch the airbag 106, so that the airbag 106 passes through the air guide tube 107. The gas in the sealing cylinder 103 is extracted. When the gas in the sealing cylinder 103 is extracted, the sealing slide rod 104 and the lifting baffle 101 can be lowered and reset. In addition, when the mounting frame 61 moves downward, it can press down the third connecting rod 124 at the N end of the trough 1, so that the second rack 117 moves downward. When the second rack 117 moves downward, when the feeding hopper 2 moves from the N end to the M end, the second gear 116 will not engage with the second rack 117. In summary, when the feeding hopper 2 moves from the N end to the M end of the trough 1, the feeding belt 112 will not rotate, that is, the device will not perform a discharging action. When the feeding hopper 2 moves from the M end to the N end of the trough 1, the feeding belt 112 will rotate, that is, the device will perform a discharging action.
