Description

Technical Field

[0001] This utility model relates to livestock and poultry breeding machinery and equipment, and in particular to a quantitative feeder. Background Technology

[0002] For breeding chickens, it is essential to strictly control their daily feed intake, employing quantitative and restricted feeding to ensure robust growth and vigorous egg production. Chinese Patent Publication No. CN102499119A discloses a quantitative feeder for breeding chickens, comprising a feed hopper, feed tray, feed funnel, feed pipe, and sealing ball. The feed pipe features a telescopic structure with a metering skirt at its bottom to adjust the feed amount. During use, the user adjusts the height of the metering skirt by pulling a rope to achieve precise feed adjustment. However, in actual use, because the metering skirt needs to move up and down the feed hopper to adjust its height, uneven rope tension can easily cause the metering skirt to tilt within the hopper. When the metering skirt tilts, the amount of feed between the downward-sloping end of the metering skirt and the feed funnel decreases, while the upward-sloping end of the metering skirt may not be fully filled, leading to inaccurate feed addition and reduced metering accuracy of the breeding chicken quantitative feeder. Therefore, how to design a feeder that improves metering accuracy is the technical problem that this utility model aims to solve. Summary of the Invention

[0003] This invention proposes a quantitative feeder to improve the metering accuracy of the quantitative feeder.

[0004] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0005] This utility model provides a quantitative feeder, comprising:

[0006] A material hopper, the top of which is provided with a top cover, and the top cover is provided with an installation port;

[0007] A material discharge hopper, wherein the material discharge hopper is provided with a material discharge port and is located at the bottom of the material bucket;

[0008] A material tray is disposed at the bottom of the material bucket and is located below the material discharge funnel;

[0009] The material discharge pipe is a telescopic sleeve, and the upper end of the material discharge pipe is disposed in the installation port;

[0010] A metering disc, the edge of which is provided with multiple guide ribs arranged vertically, and a through opening provided on the metering disc, the through opening being connected to the material discharge pipe;

[0011] A sealing ball is disposed in the material hopper and configured to open and close the discharge port of the discharge funnel.

[0012] In one embodiment of this application, the guide ribs are radially distributed around the center of the metering disc.

[0013] In one embodiment of this application, the outer end of the guide rib forms a friction contact portion, and the cross-section of the friction contact portion is an arc-shaped structure.

[0014] In one embodiment of this application, a connecting cylinder is provided on the metering disc, and the through port is connected to the material discharge pipe through the connecting cylinder;

[0015] The guide ribs extend to the connecting cylinder, and multiple guide ribs are distributed around the connecting cylinder.

[0016] In one embodiment of this application, an annular enclosure is further provided on the measuring plate, and the annular enclosure is arranged around the connecting cylinder;

[0017] The guide ribs include a first rib and a second rib. The first rib is disposed between the annular enclosure and the connecting cylinder, and the second rib is connected between the edge of the annular enclosure and the metering disc.

[0018] In one embodiment of this application, the metering plate is further provided with a plurality of first vent holes, which are arranged between the annular enclosure and the connecting cylinder;

[0019] The top cover is provided with a plurality of second vent holes, which are located on the outside of the mounting port.

[0020] In one embodiment of this application, the outer wall of the connecting cylinder is further provided with a lifting lug, a first connecting rope is provided on the lifting lug, and a first threading hole is provided on the top cover, through which the first connecting rope passes.

[0021] In one embodiment of this application, the metering disc is provided with a second threading hole, the top cover is provided with a third threading hole, and the sealing ball is provided with a second connecting rope, which passes through the second threading hole and the third threading hole.

[0022] In one embodiment of this application, the lower surface of the measuring disc is a concave structure, and the through-hole is arranged in the middle region of the concave structure.

[0023] Compared with existing technologies, the advantages and positive effects of this invention are as follows: By setting multiple vertically arranged guide ribs on the edge of the metering disc, when the metering disc tilts due to uneven force during its up-and-down movement, the top of the guide ribs will contact the inner wall of the material hopper to straighten the metering disc. Simultaneously, the vertical extension of the guide ribs guides and supports the metering disc during its up-and-down movement, effectively guiding its trajectory and ensuring it remains relatively horizontal and stable. Unlike traditional technologies that rely solely on ropes to pull the metering disc, the guide ribs greatly prevent tilting caused by uneven rope tension, ensuring the metering disc remains relatively horizontal. This, in turn, maintains precise spatial volume between the metering disc and the bottom discharge hopper, thereby improving the metering accuracy of the quantitative feeder.

[0040] Reference Figures 1-4 As shown, the quantitative feeder in this embodiment includes:

[0041] Material bucket 1, the top of which is provided with a top cover 11, and the top cover 11 is provided with an installation port 12;

[0042] The material discharge hopper 2 is provided with a material discharge port 21 and is located at the bottom of the material bucket 1;

[0043] Material tray 3 is disposed at the bottom of the material bucket 1 and is located below the material discharge funnel 2;

[0044] The material discharge pipe 6 is a telescopic sleeve, and the upper end of the material discharge pipe 6 is disposed in the mounting port 12;

[0045] Metering disc 4, the edge of which is provided with multiple guide ribs 41, the guide ribs 41 are arranged vertically, and the metering disc 4 is provided with a through opening 42, which is connected to the material discharge pipe 6.

[0046] A sealing ball 5 is disposed in the material bucket 1 and configured to open and close the discharge port 21 of the discharge funnel 2.

[0047] Specifically, the edge of the metering disc 4 is provided with multiple guide ribs 41. The guide ribs 41 are arranged vertically along the height direction of the feed hopper 1. During use, when it is necessary to adjust the feed amount of the quantitative feeder, the metering disc 4 is subjected to force and moves up and down in the feed hopper 1 to adjust the height distance between the metering disc 4 and the bottom discharge funnel 2, thereby adjusting the volume of the storage space formed between the metering disc 4 and the discharge funnel 2 in the feed hopper 1.

[0048] During the adjustment of the metering disc 4's vertical movement, the guide ribs 41 move up and down along the inner wall of the feed hopper 1, following the metering disc 4. When the metering disc 4 tilts due to unbalanced forces, the top of the corresponding guide rib 41 will abut against the inner wall of the feed hopper 1 to limit the tilt of the metering disc 4. Furthermore, the guiding effect of the guide ribs 41 against the inner wall of the feed hopper 1 allows the metering disc 4 to move up and down in a balanced state within the feed hopper 1, ensuring that the metering disc 4 remains basically horizontal within the feed hopper 1. This ensures that after the metering disc 4 is adjusted to the correct height, the space volume formed between the metering disc 4 and the feed hopper 2 within the feed hopper 1 reaches a relatively accurate capacity, allowing the feed stored in the metering disc 4 and the feed hopper 2 to meet the quantitative feeding requirements, thereby improving the accuracy of metering.

[0049] In one embodiment, the guide ribs 41 are radially distributed around the center of the metering disc 4.

[0050] Specifically, the guide ribs 41 are radially distributed around the center of the metering disc 4, which can evenly distribute the force on the metering disc 4 during movement from multiple directions, avoiding tilting caused by uneven local force. During the up-and-down movement of the metering disc 4, the radial structure can make the contact between the guide ribs 41 and the inner wall of the material bucket 1 more balanced, further ensuring that the metering disc 4 maintains a basically horizontal state during up-and-down movement.

[0051] In one embodiment, the outer end of the guide rib 41 forms a friction contact portion 410, and the cross-section of the friction contact portion 410 is an arc-shaped structure.

[0052] Specifically, the friction contact portion 410 at the outer end of the guide rib 41 adopts an arc-shaped cross-section. When in contact with the inner wall of the material bucket 1, it can transform point contact or line contact into arc-shaped surface contact, reducing wear at the contact points. At the same time, the arc-shaped structure can reduce friction during movement, making it easier to adjust the metering disc 4 up and down, and avoiding scratches on the inner wall of the material bucket 1 caused by sharp corner contact, thus extending the service life of the equipment.

[0053] In one embodiment, a connecting cylinder 43 is provided on the metering disc 4, and the through port 42 is connected to the material discharge pipe 6 through the connecting cylinder 43;

[0054] The guide ribs 41 extend to the connecting cylinder 43, and multiple guide ribs 41 are distributed around the connecting cylinder 43.

[0055] Specifically, the connecting cylinder 43 on the metering disc 4 achieves stable communication with the feed pipe 6, while the guide ribs 41 extend to the connecting cylinder 43 and are distributed around it, strengthening the structural connection between the connecting cylinder 43 and the edge of the metering disc 4, and improving the overall structural strength of the metering disc 4. When feed flows through the through-hole 42 and the connecting cylinder 43, this structure can reduce the shaking of the metering disc 4 caused by feed impact, ensuring the stability of feed flow. Furthermore, the design of the connecting cylinder 43 increases the overall weight of the metering disc 4, so that when the metering disc 43 moves downward to adjust its height, the weight can be used to adjust the movement more smoothly.

[0056] In one embodiment, the metering disc 4 is further provided with an annular enclosure 44, which is arranged around the connecting cylinder 43;

[0057] The guide rib 41 includes a first rib 411 and a second rib 412. The first rib 411 is disposed between the annular enclosure 44 and the connecting cylinder 43, and the second rib 412 is connected between the edge of the annular enclosure 44 and the metering disc 4.

[0058] Specifically, the annular enclosure 44 is arranged around the connecting cylinder 43, and together with the first rib 411 (located between the annular enclosure 44 and the connecting cylinder 43) and the second rib 412 (connecting the annular enclosure 44 and the edge of the metering disc 4), a layered support structure is formed. This not only further enhances the structural rigidity of the metering disc 4, but also guides the feed passing through the through-hole 42, preventing feed from accumulating on the metering disc 4 and allowing the feed to enter the feed pipe 6 more smoothly. Similarly, the annular enclosure 44 also helps to increase the overall weight of the metering disc 4.

[0059] In one embodiment of this application, the metering disc 4 is further provided with a plurality of first vent holes 45, which are arranged between the annular enclosure 44 and the connecting cylinder 43.

[0060] The top cover 11 is provided with a plurality of second vent holes 13, which are located on the outside of the mounting port 12.

[0061] Specifically, the first vent 45 on the metering disc 4 (located between the annular enclosure 44 and the connecting cylinder 43) and the second vent 13 on the top cover 11 (located outside the mounting port 12) allow air circulation between the inside of the feed hopper 1 and the outside. During the feed's descent, the air in the feed hopper 1 can be exchanged and circulated with the outside through the vents, preventing the air pressure inside the feed hopper 1 from increasing and hindering the feed's descent, thus ensuring the continuity of feed flow.

[0062] In one embodiment, the outer wall of the connecting cylinder 43 is further provided with a lifting lug 46, a first connecting rope is provided on the lifting lug 46, and a first threading hole 14 is provided on the top cover 11, through which the first connecting rope passes.

[0063] Specifically, the lifting lugs 46 on the outer wall of the connecting cylinder 43 are connected by a first connecting rope, which passes through the first threading hole 14 of the top cover 11, providing a stable force point for adjusting the height of the measuring disc 4. Users can easily adjust the height of the measuring disc 4 by pulling the first connecting rope. The positioning function of the first threading hole 14 can prevent the first connecting rope from getting tangled, making the adjustment operation simpler and more reliable, while ensuring that the measuring disc 4 is evenly stressed and reducing the risk of tilting.

[0064] In one embodiment, the metering disc 4 is provided with a second threading hole 47, the top cover 11 is provided with a third threading hole 15, and the sealing ball 5 is provided with a second connecting rope, which passes through the second threading hole 47 and the third threading hole 15.

[0065] Specifically, the second connecting rope of the sealing ball 5 passes through the second threading hole 47 of the metering disc 4 and the third threading hole 15 of the top cover 11, making the direction of the connecting rope more regular and avoiding entanglement with other components.

[0066] In one embodiment, the lower surface of the measuring disc 4 is a concave structure, and the through-hole 42 is arranged in the middle region of the concave structure.

[0067] Specifically, the lower surface of the metering disc 4 has a concave structure, and the through-hole 42 is arranged in the middle area of ​​the concave structure. In this way, as the feed falls through the through-hole 42, the arc-shaped contour of the concave structure can form a natural flow path, dispersing the feed on the lower surface of the metering disc 4. The through-hole 42 is located at the highest point to deliver the feed downwards, ensuring that the feed can fill the space between the metering disc 4 and the discharge funnel 2 to the maximum extent.

[0068] Compared with existing technologies, the advantages and positive effects of this invention are as follows: By setting multiple vertically arranged guide ribs on the edge of the metering disc, when the metering disc tilts due to uneven force during its up-and-down movement, the top of the guide ribs will contact the inner wall of the material hopper to straighten the metering disc. Simultaneously, the vertical extension of the guide ribs guides and supports the metering disc during its up-and-down movement, effectively guiding its trajectory and ensuring it remains relatively horizontal and stable. Unlike traditional technologies that rely solely on ropes to pull the metering disc, the guide ribs greatly prevent tilting caused by uneven rope tension, ensuring the metering disc remains relatively horizontal. This, in turn, maintains precise spatial volume between the metering disc and the bottom discharge hopper, thereby improving the metering accuracy of the quantitative feeder.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
