Description

Technical Field

[0001] This utility model relates to the field of feed dispensing equipment, specifically to an anti-retention feeding device for livestock and a livestock feeder having the feeding device. Background Technology

[0002] Currently, the aquaculture industry is gradually becoming automated. For example, a livestock feeder is used for automatic feed dispensing. The feeder includes a hopper, a feeding device, and a throwing disc. The feeding device has a feed pusher inside its feeding channel, which pushes the feed falling from the hopper into the feeding channel to the end of the channel. The feed then falls into the throwing disc by gravity. A throwing motor drives the throwing disc to rotate, and a paddle on the disc throws the feed outwards. Another example is the Chinese utility model patent publication CN221769032U, "An anti-blocking feeding device for a livestock feeder." This feeding device includes a channel shell and a motor assembly. The channel shell forms a feeding channel, and the feeding... The channel includes a lower cylindrical shell and an upper cylindrical shell. The upper end of the lower cylindrical shell is connected to the lower end of the upper cylindrical shell. The inner radius of the upper cylindrical shell is larger than the inner radius of the lower cylindrical shell. The shaftless auger is coaxially arranged with the lower cylindrical shell. As a result, the lower end of the upper cylindrical shell and the upper end of the lower cylindrical shell are connected by a horizontal plate, which forms a stepped structure. When feed is conveyed in the feeding channel, feed is easily trapped on the stepped structure. This causes the feed to remain on the stepped structure for a long time and deteriorate, polluting the internal environment of the feeder. If the accumulated deteriorated feed falls onto the throwing plate, it will affect the health of the farmed animals. Therefore, it is necessary to improve the above-mentioned feeding device. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a feeding device for preventing feed stagnation in the feeding channel.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] The present invention discloses a feeding device for preventing stagnation in aquaculture, comprising a channel shell and a shaftless auger. The channel shell forms a feeding channel, and the shaftless auger is coaxially disposed within the feeding channel. The feeding channel includes a lower half-cylinder shell, an upper half-cylinder shell, and a guide arc plate. The lower half-cylinder shell and the upper half-cylinder shell are coaxially disposed. The inner radius of the upper half-cylinder shell is larger than the inner radius of the lower half-cylinder shell. The upper end of the guide arc plate is tangentially connected to the upper half-cylinder shell, and the lower end of the guide arc plate is connected to the upper end of the lower half-cylinder shell. The channel shell forms a feeding funnel, and the lower end of the feeding funnel is connected to the upper side of the first end of the upper half-cylinder shell. The lower side of the tail end of the lower half-cylinder shell is provided with a discharge port.

[0006] Preferably, the feeding hopper includes two upright side plates and two guide inclined plates. The two upright side plates are distributed in a direction parallel to the axis of the feeding channel, and the two guide inclined plates are symmetrically distributed on both sides of the axis of the feeding channel, with the two guide inclined plates gradually approaching each other from top to bottom.

[0007] Preferably, the lower end tangent of the guide plate is connected to the guide arc plate.

[0008] Preferably, the tail end of the guide arc plate is formed with a first chamfer, and the tail end of the first chamfer is aligned with the upper end of the lower half-cylinder shell.

[0009] Preferably, the upper cylindrical shell has a second chamfer at its tail end, and the two circumferential ends of the second chamfer are respectively connected to the corresponding first chamfer.

[0010] This utility model also provides a livestock feeding machine, including the anti-retention livestock feeding device of any of the above technical solutions; it also includes a hopper, the lower end of which is connected to the feed funnel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: (i) By setting the upper end of the guide arc plate to be tangentially connected to the upper half of the cylinder shell, and the lower end of the guide arc plate to be connected to the upper end of the lower half of the cylinder shell, the feed on the inner wall of the guide arc plate can easily slide down into the lower half of the cylinder shell under the action of gravity. Thus, the feeding device of this utility model can avoid feed retention in the feeding channel and prevent feed blockage.

Detailed Implementation

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] This utility model relates to an anti-stagnant aquaculture feeding device, such as... Figure 1 and Figure 2 As shown, the device includes a channel shell 1 and a shaftless auger 3. The channel shell 1 forms a feeding channel 11, and the shaftless auger 3 is coaxially disposed within the feeding channel 11. The axis of the feeding channel 11 extends in the left-right direction. The feeding device also includes a motor assembly 2, which drives the shaftless auger 3 to rotate. The feeding channel 11 includes a lower half-cylinder shell 111, an upper half-cylinder shell 112, and a guide arc plate 113. The lower half-cylinder shell 111 and the upper half-cylinder shell 112 are coaxially disposed. The inner radius of the upper half-cylinder shell 112 is larger than the inner radius of the lower half-cylinder shell 111, thus making the inner cavity of the upper half-cylinder shell 112 larger than the inner cavity of the lower half-cylinder shell 111. Figure 3 As shown, the upper end of the guide arc plate 113 is tangentially connected to the upper half-cylinder shell 112. The guide arc plate 113 and the upper half-cylinder shell 112 are integrally formed. The lower end of the guide arc plate 113 is connected to the upper end of the lower half-cylinder shell 111. That is to say, the guide arc plate 113 is located on the upper side of the lower half-cylinder shell 111. Figures 1 to 3 As shown, the channel shell 1 has a feed funnel 12, the lower end of which is connected to the upper side of the first end of the upper half-cylinder shell 112, as shown. Figure 5 and Figure 6 As shown, a feed inlet 131 is provided on the lower side of the tail end of the lower half-cylinder shell 111. The "head end" and "tail end" mentioned above refer to the direction of feed transfer. That is to say, the feed is pushed from the "head end" of the feeding channel 11 to the "tail end" of the feeding channel 11 by the shaftless auger 3.

[0022] like Figure 1 and Figure 2As shown, the feed inlet 131 is integrally connected to the upper end of the feed pipe 13. When the shaftless auger 3 pushes the feed, if the feed cannot be discharged from the feed pipe 13 in time, the feed can be squeezed upwards by the shaftless auger 3 to the inner top of the upper cylinder shell 112. In other words, the upper cylinder shell 112 can buffer the feed and prevent blockage. Figure 3 As shown, the guide arc plate 113 replaces the existing "horizontal plate" structure, thus avoiding the formation of a horizontal step structure. It can also be understood that the guide arc plate 113 is equivalent to a rounded corner structure formed at the connection angle between the "horizontal plate" and the upper cylindrical shell 112. However, this rounded corner structure extends directly to the lower cylindrical shell 111, thereby eliminating the existing "horizontal plate" structure. Therefore, the feed on the inner wall of the guide arc plate 113 easily slides down into the lower cylindrical shell 111 under gravity, and then the shaftless auger 3... The feed is pushed to the feed inlet 131; as the shaftless auger 3 rotates, some feed will be squeezed to the front and rear ends of the upper half-cylinder 112. Since the upper end tangent of the guide arc plate 113 is connected to the upper half-cylinder 112, the feed can smoothly turn back to the lower half-cylinder 111 along the upper half-cylinder 112. The guide arc plate 113 more effectively guides the feed to slide down into the lower half-cylinder 111. As can be seen from the above, the feeding device of this utility model can avoid feed retention in the feeding channel and avoid feed blockage.

[0023] Furthermore, such as Figure 3 and Figure 4 As shown, the feeding hopper 12 includes two upright side plates 121 and two guide ramps 122. That is, the upright side plates 121 are perpendicular to the horizontal plane, and the two upright side plates 121 are distributed in a direction parallel to the axis of the feeding channel 11, meaning the two upright side plates 121 are arranged left and right. The two guide ramps 122 are symmetrically distributed on both sides of the axis of the feeding channel 11. Thus, the two upright side plates 121 and the two guide ramps 122 form the guiding cavity of the feeding hopper 12. The two guide ramps 122 are arranged gradually closer together from top to bottom, making the guiding cavity of the feeding hopper 12 larger at the top and smaller at the bottom. Figure 1 As shown, when feed falls into the feed hopper 12, it is guided by the guide plate 122 and slides obliquely down toward the shaftless auger 3. The shaftless auger 3 then pushes the feed to the right. Since the two upright side plates 121 are distributed in a direction parallel to the axis of the feeding channel 11, the direction of feed falling is prevented from being opposite to the conveying direction of the shaftless auger 3. That is to say, if the right side of the feed hopper 12 is an inclined plate structure, the feed will slide down along the right inner wall of the feed hopper 12, and the feed will move to the left, which is not conducive to the feed being quickly pushed to the right by the shaftless auger 3.

[0024] Furthermore, such as Figure 4As shown, the lower end of the guide ramp 122 is tangentially connected to the guide arc plate 113, which facilitates the smooth transition of feed sliding down the guide ramp 122 to the guide arc plate 113, and then the feed falls into the lower half-cylinder shell 111. In the radial direction about the rotation axis of the shaftless auger 3, the gap between the outer end of the shaftless auger 3 and the inner wall of the lower half-cylinder shell 111 is set to be small (for example, about 1 mm), so the feed falling into the lower half-cylinder shell 111 can be pushed to the discharge port 131 by the shaftless auger 3, and the feed is not easily retained in the lower half-cylinder shell 111.

[0025] like Figure 1 and Figure 2 As shown, the tail end of the guide arc plate 113 has a first chamfer 102. The tail end (i.e., the right end) of the first chamfer 102 is aligned with the upper end of the lower half-cylinder shell 111. That is to say, the width of the upper end of the lower half-cylinder shell 111 in the front-to-back direction is approximately equal to the distance between the right ends of the two first chamfers 102. In other words, by forming the first chamfer 102, the inner cavity of the tail end of the feeding channel 11 gradually narrows from left to right, so that the feed is guided by the inner wall of the first chamfer 102 and converges towards the center, making it easier for the feed to fall into the discharge port 131 and avoiding the formation of a dead corner at the tail end of the guide arc plate 113. Figure 1 and Figure 5 As shown, the left part of the first chamfer 102 is a concave arc segment 1021, and the right part of the first chamfer 102 is a sloping straight segment 1022. Therefore, the feeding channel 11 narrows steeply at the location corresponding to the concave arc segment 1021, while narrowing more gently at the location corresponding to the sloping straight segment 1022. That is to say, from a top-down perspective, the angle between the sloping straight segment 1022 and the axis of the feeding channel 11 is small (approximately 6°). When the feed reaches the concave arc segment 1021, it is first noticeably pushed towards the center (in the front-to-back direction), which accelerates the feed's detachment from the guide plate 11. 3. Since the tail end of the first chamfer 102 is aligned with the upper end of the lower half-cylinder shell 111, that is, the right end of the aforementioned inclined straight section 1022 is aligned with the upper end of the lower half-cylinder shell 111, the small amount of feed that has not yet fallen into the lower half-cylinder shell 111 is guided relatively gently by the aforementioned inclined straight section 1022 to completely detach from the guide arc plate 113. In other words, by setting the aforementioned concave arc section 1021, the feed is pushed to the upper side of the discharge port 131 before reaching the tail end plate 10 of the feeding channel 11, which can make the feed fall smoothly. At the same time, setting the aforementioned inclined straight section 1022 avoids the tail end of the feeding channel 11 from being too narrow and affecting the feeding speed.

[0026] Furthermore, such as Figure 2As shown, a second chamfer 103 is formed at the tail end of the upper cylindrical shell 112. Specifically, the second chamfer 103 is formed between the upper cylindrical shell 112 and the tail end plate 10. The two circumferential ends (which can be understood as the front and rear ends) of the second chamfer 103 are respectively connected to the corresponding first chamfer 102, thereby causing the upper part of the tail end of the feeding channel 11 to contract, which is beneficial for the feed that reaches the upper part of the tail end of the feeding channel 11 to be guided downward by the second chamfer 103.

[0027] This utility model relates to a livestock feeder, such as... Figure 6 and Figure 7 As shown, the feeder includes a hopper 5. The feeder of this invention also includes the anti-stagnant feed feeding device mentioned above. The lower end of the hopper 5 is connected to the feed funnel 12. The feeder has a housing and a base. The feed throwing plate 4 of the feeder is located inside the base. The housing cover is located on the base. The hopper 5 is located inside the housing. The feed channel 11 is located on the upper side of the base. The lower end of the feed drop pipe 13 passes through the top of the base. The lower end of the feed drop pipe 13 is located above the feed throwing plate 4. Because the feeder of this invention is equipped with the anti-stagnant feed feeding device of this invention, the situation of feed stagnation in the feed channel 11 can be avoided, thus preventing feed blockage.
