Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of aquaculture, and in particular to a throwing 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 including 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 centrifugal blades.

[0003] Existing pneumatic feeders include 360-degree pneumatic feeders and single-sided pneumatic feeders. The 360-degree pneumatic feeder can throw the feed at 360 degrees. However, the 360-degree pneumatic feeder has the problem that the throwing angle cannot be adjusted, a long feed pipe must be used, the cost is high, and it cannot be used in a breeding scene with a smaller area. Single-sided pneumatic feeders usually have a shell on the throwing mechanism to constrain the throwing direction of the feed particles, which will cause the feed particles to collide and wear multiple times in the shell, resulting in large feed breakage and waste. In addition, the existing single-sided pneumatic feeder has a complex structure, high cost, and is prone to failure. Because the metal shell is used to constrain the throwing angle, the feed will collide multiple times between the shell and the blades, causing the feed to break and waste. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0031] The utility model provides a throwing mechanism, which is a single-side spiral throwing mechanism. The throwing mechanism can be applied to feeding machines such as air-conveying feeding machines. The following will take the application of the throwing mechanism in the air-conveying feeding machine as an example for introduction. Figure 1 and Figure 2 A preferred embodiment of the throwing mechanism provided by the utility model is shown.

[0032] See also Figure 1 and Figure 2 In the present embodiment, the throwing mechanism 100 comprises a columnar body 1, which is extended in the up-down direction, and a feed port 2 and a discharge port 3 are respectively provided at the upper and lower ends of the columnar body 1; a feeding channel 4 is provided in the columnar body 1, and the feeding channel 4 is extended in the circumferential direction of the columnar body 1, and the two ends of the feeding channel 4 are respectively connected to the feed port 2 and the discharge port 3; wherein, a spiral feeding slope 5 is provided on the lower channel wall of the feeding channel 4, and the spiral feeding slope 5 spirally extends from the feed port 2 to the discharge port 3 along the circumference of the columnar body 1 and in the up-down direction.

[0033] Specifically, the columnar body 1 is usually arranged in a cylindrical shape, and the columnar body 1 is arranged in a cylindrical shape as an example. A feeding channel 4 is arranged in the columnar body 1, and the feeding channel 4 connects the feeding port 2 and the discharging port 3. Figure 1 and Figure 3 The columnar body 1 is arranged between the throwing disc 200 and the motor 300, and the discharge port 3 of the throwing mechanism 100 is connected to the throwing disc 200. When the feeder 1000 is working, the throwing disc 200 rotates under the drive of the motor 300, and negative pressure is generated at the center of the throwing disc 200 and the center of the throwing mechanism 100, so that the feed particles in the silo are sucked into the feeding channel 4 of the throwing mechanism 100 from the feed inlet 2, and then enter the throwing disc 200 from the discharge port 3, and are thrown out through the throwing disc 200.

[0034] Feed particles can only be thrown out at the angle limited by the discharge port 3. By changing the angle of the discharge port 3 on the horizontal projection plane, the angle of the feed particles can be restricted to meet the needs of different breeding species. Figure 1 and Figure 2 In this embodiment, the discharge port 3 is an arc-shaped port extending along the circumference of the columnar body 1 , and the feed particles can only be thrown out through the angle limited by the arc-shaped discharge port 3 .

[0035] For further information, see Figure 1 and Figure 2 In this embodiment, the angle of the discharge port 3 around the axis of the columnar body 1 is less than 180 degrees. The angle of the projection of the discharge port 3 on the horizontal plane around the axis of the columnar body 1 is less than 180 degrees. Except for the angle covered by the discharge port 3, the other angles of the columnar body 1 are closed structures, and feed particles or airflow are not allowed to pass through.

[0036] The lower channel wall of the feeding channel 4 is provided with a spiral feeding slope 5, and the spiral feeding slope 5 will form a spiral rising airflow in the feeding channel 4. The airflow can drive the feed particles to spirally rise along the spiral feeding slope 5, reduce the collision between the feed particles and the channel wall of the feeding channel 4, and maintain the speed of the feed particles moving forward in the horizontal direction, while generating an upward movement component. After the feed particles reach the top of the spiral feeding slope 5 and leave the throwing mechanism 100 from the discharge port 3, they can have a larger initial velocity, thereby increasing the throwing distance of the feeder 1000 and reducing the breakage of the feed.

[0037] The throwing mechanism 100 of the utility model is provided with a feed port 2 and a discharge port 3. After the feed particles enter the feeding channel 4 from the feed port 2, they can be thrown out from the discharge port 3, and the feed particles can only be thrown out at the angle limited by the discharge port 3. The feeder 1000 using the throwing mechanism 100 can restrict the throwing range by modifying the angle of the discharge port 3, and there is no need to set a baffle plate outside the throwing plate 200 of the feeder 1000, thereby avoiding the collision between the feed particles and the baffle plate, reducing the feed breakage and waste; and the feeding channel 4 is provided with a spiral feeding slope 5, through which a spiral rising airflow can be formed in the feeding channel 4, the airflow can drive the feed particles to spirally rise, reduce the collision between the feed particles and the channel wall of the feeding channel 4, and maintain the speed of the feed particles in the horizontal direction, while generating an upward motion component, which allows the feed particles to have a larger initial velocity when leaving the throwing mechanism 100, increasing the throwing distance of the feeder 1000 and reducing the feed breakage.

[0038] The specific arrangement of the feeding channel 4 in the inner columnar body 1 can be set according to actual conditions. Figure 1 and Figure 2 In the present embodiment, the throwing mechanism 100 further includes a motor sleeve 6, which is extended in the up-down direction. The motor sleeve 6 and the columnar body 1 are both hollow. The columnar body 1 is sleeved on the outside of the motor sleeve 6. A spiral partition 5a is provided between the columnar body 1 and the motor sleeve 6. The spiral partition 5a is extended along the circumference of the columnar body 1 and in the up-down direction to form a feeding channel 4 between the motor sleeve 6 and the columnar body 1 and on the upper side of the spiral partition 5a. The upper plate surface of the spiral partition 5a is a spiral feeding slope 5.

[0039] Specifically, the columnar body 1 and the motor sleeve 6 are coaxially arranged, the diameter of the motor sleeve 6 is smaller than the diameter of the columnar body 1, and the columnar body 1 and the motor sleeve 6 form a two-layer cylindrical structure of the throwing mechanism 100. The motor sleeve 6 runs through the entire throwing mechanism 100 from top to bottom, so that the motor shaft of the motor 300 passes through the throwing mechanism 100 from the motor sleeve 6 and is connected to the throwing plate 200 above.

[0040] The spiral partition 5a is connected between the columnar body 1 and the motor sleeve 6, so that a feeding channel 4 is formed between the motor sleeve 6 and the columnar body 1 and on the upper side of the spiral partition 5a through the columnar body 1, the motor sleeve 6, and the spiral partition 5a. The upper plate surface of the spiral partition 5a forms a spiral feeding slope 5, and the spiral feeding slope 5 can be a smooth spiral surface or the like.

[0041] For further information, see Figure 1 and Figure 2In this embodiment, the throwing mechanism 100 also includes an annular top sealing plate 7, which is sleeved on the motor sleeve 6, and the top sealing plate 7 is arranged at the upper end of the columnar body 1 in a sealing manner.

[0042] Specifically, the upper end of the columnar body 1 is open, the top sealing plate 7 covers the upper opening of the columnar body 1 , and the upper end of the motor shaft sleeve 6 passes through the top sealing plate 7 from the middle of the top sealing plate 7 .

[0043] In other embodiments, the upper end of the columnar body 1 is open to allow the feeding channel 4 to open upwards. That is, the upper end of the columnar body 1 is not provided with a top sealing plate 7, so that the feeding channel 4 is open upwards.

[0044] Optionally, see Figure 1 and Figure 2 In this embodiment, one end of the spiral partition 5 a close to the feed port 2 is connected to the lower edge of the feed port 2 .

[0045] Specifically, the spiral feeding slope 5 spirally rises around the motor shaft sleeve 6 , the bottom of the spiral feeding slope 5 is lower than the lower edge of the feed port 2 , and the top of the spiral feeding slope 5 is connected to the bottom of the feed port 2 .

[0046] Optionally, see Figure 1 and Figure 2 In this embodiment, the throwing mechanism 100 also includes a first isolation baffle 8 and a second isolation baffle 9. The first isolation baffle 8 is arranged between the columnar body 1 and the motor sleeve 6. The first isolation baffle 8 and the top sealing plate 7 are spaced apart from each other in the upper and lower directions. The end of the first isolation baffle 8 close to the columnar body 1 is connected to the lower edge of the discharge port 3, and the first isolation baffle 8 is connected to the end of the spiral partition 5a close to the discharge port 3; the second isolation baffle 9 is arranged between the columnar body 1 and the motor sleeve 6, the upper end and the lower end of the second isolation baffle 9 are respectively connected to the top sealing plate 7 and the first isolation baffle 8, and the end of the second isolation baffle 9 close to the columnar body 1 is connected to the side edge of the discharge port 3 away from the spiral partition 5a.

[0047] Specifically, the first isolation baffle 8 is arranged horizontally, while the second isolation baffle 9 is arranged vertically. The two ends of the first isolation baffle 8 in the radial direction of the columnar body 1 are respectively connected to the motor sleeve 6 and the lower edge of the discharge port 3, while the two ends of the first isolation baffle 8 in the circumferential direction of the columnar body 1 are respectively connected to the lower end of the second isolation baffle 9 and the top of the spiral partition 5a. The upper end of the second isolation baffle 9 is connected to the top sealing plate 7, one end of the second isolation baffle 9 is connected to the motor sleeve 6, and the end of the second isolation baffle 9 away from the motor sleeve 6 is connected to the side edge of the discharge port 3 away from the top of the spiral partition 5a.

[0048] After the feed particles enter the feed port 2, the airflow will drive the feed particles to spirally rise along the spiral feeding slope 5, and leave the throwing mechanism 100 from the discharge port 3 after reaching the top of the spiral feeding slope 5. The setting of the first isolation baffle 8 and the second isolation baffle 9 is conducive to allowing the feed particles to leave the throwing mechanism 100 from the discharge port 3, and the setting of the first isolation baffle 8 and the second isolation baffle 9 is conducive to restricting the throwing angle of the feed particles through the discharge port 3.

[0049] For further information, see Figure 1 and Figure 2 In this embodiment, the second isolation baffle 9 is arranged along the radial direction of the columnar body 1.

[0050] Specifically, the first isolation baffle 8 is arranged in a fan shape, and the central angle of the first isolation baffle 8 is equal to the surrounding angle of the discharge port 3 around the axis of the columnar body 1. The length of the arc side of the first isolation baffle 8 close to the columnar body 1 is equal to the length of the discharge port 3 in the extension direction. The second isolation baffle 9 is an inclined plate arranged along the radial direction of the columnar body 1 and inclined relative to the central axis of the discharge port 3, so that the plate surface of the second isolation baffle 9 close to the discharge port 3 forms a reflective inclined surface, which can guide the feed particles in the feeding channel to the discharge port 3.

[0051] Optional, see Figure 1 and Figure 2 In this embodiment, a flange structure 11 is provided at the lower end of the columnar body 1 , and the columnar body 1 can be fixedly mounted on the motor 300 through the flange structure 11 .

[0052] Optional, see Figure 1 and Figure 2 In this embodiment, the feed port 2 and the discharge port 3 are located on the same side of the axis of the columnar body 1 .

[0053] Specifically, a feed port 2 is provided on one side of the lower end of the columnar body 1 that deviates from the axis, and the feed port 2 and the discharge port 3 are located on the same side of the axis of the columnar body 1 in the radial direction of the columnar body 1. Since the feed port 2 and the discharge port 3 are provided on the same side of the axis of the columnar body 1, it is beneficial to extend the length of the feeding channel 4.

[0054] Optional, see Figure 1 and Figure 2 In this embodiment, a feed pipe 10 is provided on the columnar body 1 , and a feed port 2 is provided at an end of the feed pipe 10 away from the columnar body 1 .

[0055] Specifically, the feed pipe 10 is extended in the horizontal direction, one end of the feed pipe 10 is arranged on the columnar body 1 and is connected to the lower end of the columnar body 1, and the feed port 2 is arranged at the end of the feed pipe 10 away from the columnar body 1, wherein the feed pipe 10 is generally a circular tube, and the axis of the feed pipe 10 and the discharge port 3 are located on the same side of the axis of the columnar body 1.

[0056] Optional, see Figure 1 and Figure 2 In this embodiment, the projection of the feed port 2 on the columnar body 1 is opposite to one end of the discharge port 3 in the axial direction of the columnar body 1. That is, the projection of the feed port 2 on the columnar body 1 is opposite to the first end of the discharge port 3 in an upward and downward manner.

[0057] The utility model also provides a feeding machine, which can be a pneumatic feeding machine, etc. The feeding machine is a single-side pneumatic feeding machine, and the feeding machine includes a throwing mechanism. Since the throwing mechanism adopts the technical solution of the above embodiment, it has the beneficial effects brought by the technical solution of the above embodiment. Figure 3 A preferred embodiment of the feeding machine provided by the utility model is shown.

[0058] See also Figure 3 In this embodiment, the feeder 1000 also includes a throwing tray 200 and a motor 300.

[0059] Specifically, the feeder 1000 is also composed of a throwing mechanism 100, a throwing disc 200, a motor 300 and a floating device 400. A feed inlet 2 is provided on the side of the throwing mechanism 100, and the feed inlet 2 is connected to the silo through a feeding pipe. When the feeder 1000 is working, the throwing disc 200 rotates under the drive of the motor 300, and a negative pressure is generated at the center of the throwing disc 200 and the center of the throwing mechanism 100, so that the feed particles in the silo are sucked into the feeding channel 4 of the throwing mechanism 100 from the feed inlet 2, and the airflow can drive the feed particles to spirally rise along the spiral feeding slope 5, and after reaching the top of the spiral feeding slope 5, the feed particles leave the throwing mechanism 100 from the discharge port 3, enter the throwing disc 200, and are thrown out by the throwing disc 200 rotating around the throwing mechanism 100.

[0060] When the throwing disc 200 is working, the throwing disc 200 will generate negative pressure in the feeding channel 4 of the throwing mechanism 100. Since the feeding channel 4 is provided with a spiral feeding slope 5, a spiral rising airflow can be formed in the feeding channel 4 through the spiral feeding slope 5. The airflow can drive the feed particles to spirally rise, reduce the collision between the feed particles and the channel wall of the feeding channel 4, and maintain the speed of the feed particles moving in the horizontal direction, while generating an upward movement component, which allows the feed particles to have a larger initial velocity when leaving the throwing mechanism 100, thereby increasing the throwing distance of the feeder 1000 and reducing the breakage of the feed.

[0061] 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.

[0062] 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.
