Abstract
Description
Technical Field
[0001] The embodiments of the utility model relate to the technical field of breeding, and in particular to a feeding mechanism and a feeding machine. Background Art
[0002] Feeding machine is a kind of mechanical device commonly used in the breeding field, which is used to feed the animals at a fixed time and quantity. In the field of aquaculture, the pneumatic feeding machine that uses wind power to transmit feed is a commonly used breeding machine. A typical pneumatic feeding machine consists of a main machine containing a silo, a throwing mechanism, and a pipeline connecting the main machine and the throwing mechanism. The main machine is used to store feed particles, and the throwing mechanism is used to generate negative pressure to extract feed particles from the main machine silo through the pipeline and throw the feed particles out through the centrifugal blades. Please refer to Figure 1 The pneumatic feeder is commonly used in the field of aquaculture. In order to evenly spread the feed particles into the water, the throwing mechanism 100a needs to be installed on a float and placed in the middle of the pond, and the main machine 200a needs to be placed on the shore for easy loading. Therefore, the main machine 200a needs to be connected to the throwing mechanism 100a through a pipe 300a, and the wind force generated by the throwing mechanism 100a needs to be used to extract the feed particles from the main machine 200a and throw them out.
[0003] See also Figures 2 to 4 The existing 360-degree pneumatic feeding machine's throwing mechanism 100b includes a negative pressure throwing plate 1b, a feeding mechanism 2b and a motor 3b. After the above components are assembled together, they need to be rigidly mounted on a float (not shown in the figure) to keep floating on the water surface through the float. The float can be any floating device that can provide sufficient buoyancy and maintain balance.
[0004] See also Figure 2 The working principle of the throwing mechanism 100b is as follows: the feeding mechanism 2b is a structure that can be connected to a hollow pipe, which is rigidly fixed to the main housing of the motor 3b (not rotating with the motor shaft), and the negative pressure throwing plate 1b is fixed to the motor shaft of the motor 3b, and can rotate under the drive of the motor shaft after the motor 3b is powered on. Figure 3 The main body of the feeding mechanism 2b is a hollow cylinder with a feeding port 21b on its side. After the feed particles enter the feeding mechanism 2b through the pipe from the feeding port 21b, they move toward the upper discharge port 22b and enter the negative pressure throwing plate 1b under the negative pressure generated by the upper negative pressure throwing plate 1b. Figure 4The negative pressure throwing plate 1b is composed of a circular upper plate surface 12b and a lower plate surface 13b, and a plurality of throwing blades 14b between the two plates. A circular air inlet 15b is provided in the center of the lower plate surface 13b for extracting feed particles from below, and a motor sleeve 11b is provided in the center of the upper plate surface 12b for fixing the negative pressure throwing plate 1b on the motor shaft. When the negative pressure throwing disc 1b rotates driven by the motor 3b, the throwing blades 14b will throw the air in the center of the negative pressure throwing disc 1b to the surroundings, producing the effect of a centrifugal fan. At this time, the negative pressure throwing disc 1b will inhale air at high speed from the air inlet 15b in the center of the lower disc surface 13b. Since the feeding mechanism 2b is connected to the bottom of the negative pressure throwing disc 1b, the negative pressure generated will inhale air at high speed from the feeding pipe connected to the feeding mechanism 2b, and the air will drive the feed particles in the silo to continuously move toward the negative pressure throwing disc 1b, continuously enter the negative pressure throwing disc 1b from below through the feeding pipe and the feeding mechanism 2b, and be thrown to the surroundings under the push of the throwing blades 14b of the negative pressure throwing disc 1b, thereby achieving the feeding effect.
[0005] The characteristic of the throwing mechanism 100b is that after the feed enters the center of the throwing disk from the bottom of the throwing disk, it will be thrown from any direction by the throwing disk, so the throwing range will surround the position of the throwing mechanism 100b by 360 degrees. In order to prevent the feed particles from being thrown onto the shore from one side of the connecting pipe, the throwing mechanism 100b needs to be connected to a longer pipe. In order to drive the feed through the longer pipe, the throwing mechanism 100b needs to increase the power to provide sufficient wind speed. At the same time, the throwing mechanism 100b will also increase the throwing distance. Therefore, the throwing range of the 360-degree wind-conveying feeder usually reaches 50 meters in diameter, and the length of the feed pipe is at least more than 30 meters, and a high-power motor is required. Not only is the cost high, but in order to achieve the wind pressure, a large-diameter throwing disk must be used, resulting in a long throwing distance, and it cannot be used in ponds with smaller areas. The existing 360-degree wind-conveying feeder cannot adjust the throwing angle and must use a long feed pipe, which is expensive and cannot be used in aquaculture scenarios with smaller areas.
[0006] In order to solve the limitation that the 360-degree air-conveying feeder is not suitable for smaller ponds, a single-side air-conveying feeder is designed in the prior art. Figure 5The single-side air-feeding feeder is usually composed of a blower 100c, a silo 200c, a feeding pipe 300c and a throwing device 400c, wherein the silo 200c and the blower 100c are installed on the shore, and the throwing device 400c is installed on the floating device 500c and floats in the water. The throwing device 400c can be a single-side throwing device, and the throwing device 400c is also composed of a turntable, but a shell is provided outside the turntable to limit the throwing angle, so that the feed particles can only be thrown forward after entering the throwing device 400c from the top, so the throwing device 400c can use a shorter feeding pipe 300c, which can be relatively small. However, the single-sided air-conveying feeder needs to use a blower 100c to transport feed. In order to prevent the unloading mechanism on one side of the silo 200c from backflowing into the silo 200c due to the positive pressure generated by the blower, it is also necessary to install a wind-off mechanism on the silo 200c that can pass feed but not airflow. The overall solution cost is relatively high. At the same time, because the throwing device 400c uses a shell to constrain the throwing direction of feed particles, this will cause the feed particles to collide and wear multiple times in the shell of the throwing device 400c, resulting in large feed breakage and waste. The existing single-sided air-conveying feeder has a complex structure, high cost, and is prone to failure. In addition, because the metal shell is used to constrain the throwing angle, the feed will collide multiple times between the shell and the blades, causing feed breakage and waste.

[0036] The utility model provides a feeding mechanism, which can be applied to feeding machines such as air feeding machines. The following will introduce the application of the feeding mechanism to the air feeding machine as an example. Figures 6 to 8 A preferred embodiment of the feeding mechanism provided by the utility model is shown.

The feed port 3 is connected to the discharge port 4 through the feeding channel 2, and the discharge port 4 is an arc-shaped port extending along the circumference of the columnar body 1.
[0038] Specifically, the column 1 is usually arranged in a cylindrical shape, and the column 1 is arranged in a cylindrical shape as an example. The column 1 is defined as being in an up-down direction in the axial direction, and the end of the column 1 provided with the feed port 3 is the lower end of the column 1, and the end of the column 1 provided with the discharge port 4 is the upper end of the column 1.
[0039] A feeding channel 2 is provided in the columnar body 1, and the feeding channel 2 is connected to the feeding port 3 and the discharging port 4. Figure 6 and Fig. 9The columnar body 1 is arranged between the throwing plate 200 and the motor 300, and the discharge port 4 of the feeding mechanism 100 is connected to the throwing plate 200. When the feeder 1000 is working, the throwing plate 200 rotates under the drive of the motor 300, and negative pressure is generated at the center of the throwing plate 200 and the center of the feeding mechanism 100, so that the feed particles in the silo are sucked into the feeding channel 2 of the feeding mechanism 100 from the feed port 3, and then enter the throwing plate 200 from the discharge port 4, and are thrown out through the throwing plate 200.
[0040] Feed particles can only be thrown out at an angle limited by the arc-shaped discharge port 4. By changing the angle of the discharge port 4 on the horizontal projection plane, the angle at which the feed particles are thrown out can be restricted, which is suitable for the needs of different breeding species. Figures 6 to 8 In this embodiment, the angle of the discharge port 4 around the axis of the column 1 is less than 270 degrees. The angle of the projection of the discharge port 4 on the horizontal plane around the axis of the column 1 is less than 270 degrees. Except for the angle covered by the discharge port 4, the other angles of the column 1 are closed structures, and feed particles or airflow are not allowed to pass through.

Since the feed port 3 and the discharge port 4 are provided on the same side of the axis of the columnar body 1, the feeding channel 2 connecting the feed port 3 and the discharge port 4 is extended in the up-down direction as a whole, which is conducive to all the feed particles in the feeding channel 2 being thrown out from the discharge port 4, avoiding the problem of feed particles remaining in the feeding channel 2.
[0046] The two ends of the feeding mechanism 100 of the utility model are respectively provided with a feed port 3 and a discharge port 4. After the feed particles enter the feeding channel 2 from the feed port 3, they can be thrown out from the discharge port 4, and the feed particles can only be thrown out at the angle limited by the arc-shaped discharge port 4. The feeder 1000 using the feeding mechanism 100 can restrict the throwing range by modifying the angle of the discharge port 4, and there is no need to set a baffle plate outside the throwing plate 200 of the feeder 1000, thereby avoiding the collision of the feed particles with the baffle plate and reducing the breakage and waste of the feed.
[0047] Optional, see Figures 6 to 8 In this embodiment, the columnar body 1 is hollow, and a first sealing plate 5 is provided at one end of the columnar body 1 near the discharge port 4 to cover the other end of the columnar body 1 near the feed port 3 to cover the other end of the columnar body 1 near the feed port 3. An isolation baffle 7 is provided inside the columnar body 1, and the isolation baffle 7 connects the first sealing plate 5 and the second sealing plate 6 to form a feeding channel 2 in the columnar body 1 through the isolation baffle 7, the first sealing plate 5 and the second sealing plate 6.
[0048] Specifically, two isolation baffles 7 are provided, the two isolation baffles 7 are connected and located between the first sealing plate 5 and the second sealing plate 6, the upper ends of the two isolation baffles 7 are connected to the first sealing plate 5, the lower ends of the two isolation baffles 7 are connected to the second sealing plate 6, the two ends of the two isolation baffles 7 away from each other are connected to the inner wall of the column 1, and the two ends of the two isolation baffles 7 away from each other are respectively located on both sides of the discharge port 4 in the circumferential direction of the column 1, so that the feeding channel 2 constitutes a completely closed channel except for the feed port 3 and the discharge port 4, the feed particles can only be thrown out through the angle limited by the discharge port 4, and the column 1 is completely closed at other angles except for the discharge port 4 part.

[0051] Specifically, the end of the discharge port 4 close to the feed port 3 in the circumferential direction of the columnar body 1 is defined as the first end of the discharge port 4, and the end of the discharge port 4 away from the feed port 3 in the circumferential direction of the columnar body 1 is defined as the second end of the discharge port 4. The reflecting slope 21 is located at the lower side of the discharge port 4, and the reflecting slope 21 is gradually inclined upward in the direction from the first end to the second end of the discharge port 4, and the feed particles in the feeding channel 2 can be guided upward to the discharge port 4 through the reflecting slope 21.

[0053] Specifically, the portion of the second sealing plate 6 away from the feed port 3 is gradually inclined upward in the direction from the first end to the second end of the discharge port 4 , thereby forming a reflective slope 21 on the channel wall of the feeding channel 2 .
[0054] For further information, see Figures 6 to 8 In the present embodiment, one end of the second sealing plate 6 close to the feed port 3 is gradually bent toward the discharge port 4 in the direction away from the feed port 3, thereby forming a reflection arc surface on the channel wall of the feeding channel 2 and close to the feed port 3, and the feed particles entering from the feed port 3 can be guided upward and into the feeding channel 2 through the reflection arc surface.
[0055] Optional, see Figures 6 to 8 In this embodiment, a reflective surface 22 is provided on the channel wall of the feeding channel 2. The reflective surface 22 is opposite to the discharge port 4 in the discharge direction of the discharge port 4. The reflective surface 22 is gradually curved toward the discharge port 4 in the axial direction of the columnar body 1 and away from the feeding port 3.
[0056] Specifically, the reflective surface 22 is opposite to the discharge port 4 in the discharge direction of the discharge port 4 (the discharge direction is perpendicular to the direction of the discharge port 4, that is, the radial direction of the column 1), and the reflective surface 22 is gradually curved from bottom to top toward the discharge port 4. The feed particles in the feeding channel 2 can also be guided to the discharge port 4 through the reflective surface 22.
[0057] Optional, see Figures 6 to 8 In this embodiment, a through hole for the sleeve 8 to pass through is set in the middle of the first sealing plate 5, and the first sealing plate 5 is set in a trumpet shape with a larger upper part and a smaller lower part, thereby forming a reflective curved surface 22 on the channel wall of the feeding channel 2.
[0058] Optional, see Figures 6 to 8 In this embodiment, a feed pipe 11 is provided on the columnar body 1 , and the feed port 3 is provided at one end of the feed pipe 11 away from the columnar body 1 .

[0061] The utility model also provides a feeding machine, which can be a pneumatic feeding machine, etc. The feeding machine includes a feeding mechanism. Since the feeding mechanism adopts the technical solution of the above embodiment, it has the beneficial effects brought by the technical solution of the above embodiment. Fig. 9 A preferred embodiment of the feeding machine provided by the utility model is shown.
[0062] See also Fig. 9 In this embodiment, the feeder 1000 also includes a throwing tray 200 and a motor 300.
[0063] Specifically, the feeder 1000 is also composed of a feeding mechanism 100, a throwing tray 200, a motor 300 and a floating device 400. A feeding port 3 is provided on the side of the feeding mechanism 100, and the feeding port 3 is connected to the silo through a feeding pipe. When the feeder 1000 is working, the throwing tray 200 rotates driven by the motor 300, and negative pressure is generated at the center of the throwing tray 200 and the center of the feeding mechanism 100, so that the feed particles in the silo are sucked into the feeding channel 2 of the feeding mechanism 100 from the feeding port 3, and then enter the throwing tray 200 from the discharge port 4, and are thrown out through the throwing tray 200.
[0064] When the throwing disc 200 is working, the throwing disc 200 will generate negative pressure in the feeding channel 2 of the feeding mechanism 100, sucking the feed particles into the feeding mechanism 100. After entering the feed port 3, the feed particles are reflected upward by the reflective curved surface 22, and enter the throwing disc 200 at a certain angle from the discharge port 4 and are thrown out by the throwing disc 200, thereby completing the throwing process. The feeder 1000 using the feeding mechanism 100 can adjust the throwing range by modifying the angle of the discharge port 4, so there is no need to set a baffle outside the throwing disc 200, and the collision of the feed particles with the baffle will not occur, thereby reducing breakage and waste.
[0065] The feeding machine 1000 adopts a negative pressure feeding mechanism, which only relies on the negative pressure generated by the throwing plate 200 to transport feed. It does not require a blower and an air shut-off mechanism, and has a simple structure, high reliability and low cost. The feeding machine 1000 can achieve single-sided throwing without a shell that constrains the throwing angle, which not only reduces the cost, but also significantly reduces the breakage of feed particles due to multiple collisions in the shell of the feeding machine 1000, thereby reducing feed waste. The throwing angle of the feeding machine 1000 can be changed to suit the needs of different breeding varieties.
[0066] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
