Description

Technical Field

[0001] This invention relates to the field of feed transfer technology, specifically to a pellet feed transfer robot for livestock farming. Background Technology

[0002] With social development, the scale of livestock farming continues to expand. Pellet feed is widely used due to its balanced nutrition and easy storage. Pellet feed transfer robots for livestock farming, as key equipment in automated farming systems, can realize the automatic transfer of feed from feed towers to livestock sheds, greatly reducing the intensity of manual labor.

[0003] However, since the breeding process requires the simultaneous transfer of various pelleted feeds of different diameters (such as chick feed with a diameter of about 2-3 mm and fattening pig feed with a diameter of about 4-6 mm), when the transfer robot receives feed in the feed tower, it is inevitable that fragments will be generated during the long-term storage and transportation process in the feed tower. These fragments will enter the transfer robot along with the whole feed. If they are not separated in time, the fragments will be stored mixed with the whole feed. When feeding feed later, the fragments are likely to block the discharge port or solenoid valve, causing the feed delivery to be interrupted. In addition, the nutritional value of the fragments is easily lost, and the overall quality of the feed will be reduced after mixing. If feed containing a large amount of fragments is fed for a long time, it may affect the feed intake and growth of livestock and poultry. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pellet feed transfer robot for livestock farming. It uses a filtration mechanism in its feeding system to adjust the spacing between the baffles, thereby filtering out fragments from feeds of different diameters. Combined with a vibration mechanism, it reduces feed blockage and cleans fragments from the baffle surface, thus solving the problems of fragment blockage and reduced feed quality mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a pellet feed transfer robot for livestock breeding, comprising a storage cylinder, a discharge funnel fixedly connected to the bottom of the storage cylinder, a plurality of solenoid valves fixedly installed between the storage cylinder and the discharge funnel, and a feeding mechanism fixedly installed on the top of the storage cylinder.

[0006] The feeding mechanism includes a protective cover installed on the top of the storage cylinder, a conveying pipe rotatably installed at the bottom of the feed inlet of the protective cover, and a filter mechanism installed at the bottom of the conveying pipe for filtering the feed passing through the conveying pipe. During the feeding stage, the conveying pipe rotates so that the discharge end of the conveying pipe is connected to the storage cylinder.

[0007] The filtration mechanism includes a mounting box fixedly installed at the bottom of the conveying pipe. A variable pitch screw is rotatably installed inside the mounting box. Multiple moving blocks and multiple baffles are slidably installed inside the mounting box. The moving blocks and baffles are movably connected. The variable pitch screw is threadedly connected to the moving blocks. During the filtration stage, the rotation of the variable pitch screw drives the multiple moving blocks to move in opposite directions, thereby driving the multiple baffles to move, which is used to adjust the spacing between the multiple baffles.

[0008] The mounting box has two drive motors and a vibration mechanism fixedly installed inside. The vibration mechanism includes a slide rod, and a stop bar is slidably mounted on the slide rod. The output ends of the two drive motors are respectively connected to the end of the variable pitch screw and the slide rod. The end of the stop bar away from the moving block is slidably mounted on the outer wall of the slide rod.

[0009] The movable block has a circular hole inside, and a ball bearing is movably installed inside the circular hole. The ball bearing is rolled within the variable pitch thread of the variable pitch screw.

[0010] In the above technical solutions, the feeding mechanism achieves feeding switching between different storage chambers by rotating the conveying pipe. The filtration mechanism uses the cooperation of variable pitch screw, moving block and baffle to adjust the baffle spacing to adapt to feed of different diameters, thereby achieving the filtration of broken materials.

[0011] Based on the above, mounting cavities are provided on both sides of the slide rod, and an impact strip is slidably installed inside the mounting cavity. A spring is fixedly connected between the impact strip and the mounting cavity. A sliding groove is provided inside the stop bar, and the sliding groove is sleeved on the outer wall of the slide rod. Impact grooves are provided on both sides of the inner wall of the sliding groove, and the impact strip is located inside the impact groove.

[0012] A connecting block is fixedly connected to one end of the stop bar near the movable block. A movable groove is provided on the side of the movable block near the stop bar. The connecting block is slidably installed inside the movable groove. A spring is fixedly connected between the connecting block and the movable groove.

[0013] In the above technical solution, the sliding rod rotates, causing the impact bar to repeatedly strike the impact groove of the baffle bar under the action of spring two. This, combined with spring one, causes the baffle bar to vibrate at high frequency, which not only prevents feed from clogging between the baffle bars, but also shakes off the debris adhering to the surface of the baffle bars, thereby improving filtration efficiency and cleanliness.

[0014] This invention provides a pellet feed transport robot for livestock farming. It has the following beneficial effects:

[0015] 1. This pellet feed transfer robot for livestock farming, through the setting of a feeding mechanism, activates the corresponding drive motor to drive the variable pitch screw to rotate for feeds of different diameters. The variable pitch thread of the variable pitch screw pushes multiple moving blocks to move in opposite directions along the mounting box through ball bearings. The moving blocks drive the baffles to slide synchronously along the slide bar through the connecting block, thereby precisely adjusting the spacing between the multiple baffles so that the spacing is slightly smaller than the minimum diameter of the current feed. When the feed enters the mounting box from the conveying pipe, whole feed pellets, because their diameter is larger than the spacing between the baffles, are intercepted and fall into the corresponding storage cavity of the storage cylinder, while broken feed falls into the collection box below through the spacing between the baffles, realizing the separation of broken feed from whole feed. Compared with existing transfer robots, this effectively avoids the problem of broken feed clogging the discharge port or mixed storage affecting feed quality.

[0016] 2. In this pellet feed transfer robot for livestock farming, a vibration mechanism is incorporated. During operation, the corresponding drive motor is activated to rotate the slide bar at high speed. The impact bars on both sides of the slide bar rotate with it. When the impact bars contact the inner wall of the groove of the baffle bar, they are squeezed into the mounting cavity and compress the second spring. When the slide bar rotates until the impact bars are aligned with the impact groove, the second spring releases its elasticity, ejecting the impact bars and causing them to impact the inner wall of the impact groove. At the same time, the baffle bar is connected to the spring of the moving block through the connecting block, causing the baffle bar to vibrate at high frequency. This allows the feed pellets to pass through the gap between the baffle bars more smoothly and also shakes off the debris adhering to the surface of the baffle bars into the collection box, ensuring that the filtration gap is always unobstructed and improving the stability of the filtration effect.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] When existing transfer robots simultaneously transfer multiple feeds of different diameters, fragments in the feed tower will enter the robot's interior along with whole feeds. This results in fragments being mixed and stored together with whole feeds, which can easily clog the discharge port or solenoid valve, affecting the continuity of feed feeding and reducing feed quality.

[0033] Therefore, in view of the above-mentioned problems, the present invention discloses a pellet feed transfer robot for livestock farming, with reference to... Figure 1-3 As shown, the device includes a storage cylinder 1. Multiple partitions 101 are fixedly connected inside the storage cylinder 1, dividing the interior of the storage cylinder 1 into multiple independent storage chambers for storing different feeds. An annular groove 102 is formed at the top of the storage cylinder 1, providing a trajectory for the rotation of the conveying pipe 22. Multiple feed inlets 103 are formed inside the annular groove 102, communicating with the storage chambers. The feed inlets 103 are used to introduce filtered feed into the corresponding storage chamber. Multiple discharge holes 104 are formed at the bottom of the storage cylinder 1, communicating with the bottom of the storage chambers. The discharge holes 104 are used to extract feed from the storage chambers. The storage cylinder 1 has a fixed connection to the outer wall of the outlet. The lifting lugs 105 are symmetrically distributed on both sides of the storage cylinder 1 and are used to connect the storage cylinder 1 to the hoisting equipment to facilitate the overall movement or installation of the robot. The bottom of the storage cylinder 1 is fixedly connected to the discharge funnel 3. The discharge funnel 3 is conical and can concentrate the feed output from multiple discharge holes 104 to the feeding device below. Multiple solenoid valves 4 are fixedly installed between the storage cylinder 1 and the discharge funnel 3. The feed inlet of the solenoid valve 4 is connected to the bottom of the discharge hole 104. The opening and closing of the solenoid valve 4 controls the output of the corresponding storage cavity feed to achieve precise distribution. The top of the storage cylinder 1 is fixedly installed with a feeding mechanism 2.

[0034] refer to Figure 4-9As shown, the feeding mechanism 2 includes a protective cover 21 installed on the top of the storage cylinder 1, and a conveying pipe 22 rotatably installed at the bottom of the feed inlet of the protective cover 21. The conveying pipe 22 is used to convey feed from the feed tower to the storage cylinder 1. The discharge end of the conveying pipe 22 is connected to the feed inlet 103, so that the filtered feed can enter the storage cylinder 1. A filter mechanism 25 is installed at the bottom of the conveying pipe 22 to filter out the broken material in the feed passing through the conveying pipe 22. A drive motor 23 is fixedly installed on the top of the storage cylinder 1. The drive motor 23 can precisely control the rotation angle. The output end of the drive motor 23 is connected to the bottom of the conveying pipe 22, driving the conveying pipe 22 to rotate along the annular groove 102, so that the discharge end of the conveying pipe 22 can be connected to different feed inlets. The top of the storage cylinder 1 is fixedly installed with multiple collection boxes 24 for connecting the hole 103. The collection boxes 24 are used to collect the broken material filtered out by the corresponding feed. The inlet of the collection box 24 is located at the bottom of the filter mechanism 25 to ensure that the broken material can fall accurately into the collection box 24. During the feeding stage, the conveying pipe 22 rotates so that the outlet end of the conveying pipe 22 is connected to the storage cylinder 1. The filter mechanism 25 includes a mounting box 251 fixedly installed at the bottom of the conveying pipe 22. A variable pitch screw 253 is rotatably installed inside the mounting box 251. The thread pitch of the variable pitch screw 253 gradually changes from the middle to both ends, which can drive multiple moving blocks 255 to move synchronously in opposite directions. Multiple moving blocks 255 and multiple baffles are slidably installed inside the mounting box 251. 256. The movable block 255 is movably connected to the baffle 256. The variable pitch screw 253 is threadedly connected to the movable block 255. The rotational motion of the variable pitch screw 253 is converted into the linear motion of the movable block 255 through threaded transmission. During the filtration stage, the rotation of the variable pitch screw 253 drives multiple movable blocks 255 to move in opposite directions, thereby driving multiple baffles 256 to move. This is used to adjust the spacing between the multiple baffles 256 to adapt to the filtration requirements of feeds of different diameters. Two drive motors 252 and a vibration mechanism 254 are fixedly installed inside the mounting box 251. The two drive motors 252 provide rotational power to the variable pitch screw 253 and the slide bar 2541, respectively. The vibration mechanism 254 includes a slide bar 2541. 41 is a cylindrical rod, arranged parallel to the variable pitch screw 253. The stop bar 256 is slidably mounted on the slide bar 2541, which guides the movement of the stop bar 256 and ensures that the stop bar 256 moves smoothly. The output ends of the two drive motors 252 are respectively connected to the ends of the variable pitch screw 253 and the slide bar 2541. The end of the stop bar 256 away from the moving block 255 is slidably mounted on the outer wall of the slide bar 2541. The moving block 255 has a circular hole inside, and a ball bearing 259 is movably mounted inside the circular hole. The ball bearing 259 is rolled in the variable pitch thread of the variable pitch screw 253. Through the cooperation between the ball bearing 259 and the variable pitch thread, it is ensured that multiple moving blocks 255 can move synchronously in opposite directions when the variable pitch screw 253 rotates.

[0035] refer to Figure 10-13As shown, mounting cavities are provided on both sides of the slide rod 2541. An impact strip 2542 is slidably mounted inside the mounting cavity. A spring 2543 is fixedly connected between the impact strip 2542 and the mounting cavity. The spring 2543 is always in a compressed state, providing an outward thrust to the impact strip 2542. A groove 2544 is provided inside the stop strip 256. The groove 2544 is fitted onto the outer wall of the slide rod 2541, allowing the stop strip 256 to slide along the slide rod 2541. Impact grooves 2545 are provided on both sides of the inner wall of the groove 2544. The impact strip 2542 is located inside the impact groove 2545. When the slide rod 2541... When rotating, the impact bar 2542 can impact the impact groove 2545 under the action of the second spring 2543, generating vibration. The end of the stop bar 256 near the moving block 255 is fixedly connected to the connecting block 257. The moving block 255 has a movable groove on the side near the stop bar 256. The connecting block 257 is slidably installed inside the movable groove, so that the stop bar 256 can slide and slightly shake relative to the moving block 255 along the movable groove. The connecting block 257 and the movable groove are fixedly connected to the first spring 258. The first spring 258 is a tension spring. When the stop bar 256 is impacted and vibrated, the first spring 258 can increase the vibration amplitude.
