Material throwing mechanism and batch feeder

Abstract

The utility model provides a throwing mechanism and a batch feeder, the throwing mechanism comprises an upper cover and a throwing disc, the upper cover is provided with a feed port and an annular baffle, the upper end of the annular baffle is communicated with the feed port, and the annular baffle is provided with a discharge port; the throwing disc comprises an annular upper cover, a bottom plate and blades, the annular baffle is sleeved with the annular upper cover, and the annular upper cover and the bottom plate are located on the upper side and the lower side of the discharging port respectively. Feed particles enter the annular baffle from the feeding port of the upper cover and flow out from the discharging port of the annular baffle, and due to the fact that the discharging port is located between the annular upper cover and the bottom plate of the feed throwing disc, the feed particles can only move from inside to outside in the radial direction of the feed throwing disc and are thrown out forwards under the action of the blades of the feed throwing disc. Due to the fact that the discharging port restrains the direction of the feed particles, the feed particles are strictly limited in the gap between the annular upper cover and the bottom plate and cannot be reflected by the feed throwing bin, and damage of the feed particles caused by multiple times of reflection can be remarkably reduced.

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 aquaculture field, which is used to feed aquatic animals at a fixed time and quantity. Feeding machine is usually a mechanical structure driven by an electric motor. Figure 1 A typical feeder 1000a is composed of a feed bin 100a, a feeding mechanism 200a, a throwing mechanism 300a and a control device 400a, wherein the feed bin 100a is used to store feed, and a control device 400a is usually arranged above the feed bin 100a. The control device 400a is a circuit with a microprocessor, which can control the main functions of the feeder 1000a, such as opening, closing, and timing. The feed bin 100a and the feeding device 500a below together constitute the feeder 1000a, and the feeding device 500a is composed of a feeding mechanism 200a and a throwing mechanism 300a, wherein the feeding mechanism 200a includes a vibration plate 210a and a vibrator 220a, and the feed in the feed bin 100a falls into the vibration plate 210a through the feeding port 110a, and the vibration plate 210a vibrates back and forth under the drive of the vibrator 220a, and the feed is slowly sent to the throwing mechanism 300a below. The throwing mechanism 300a is composed of a throwing disc 310a and a motor 320a. The throwing disc 310a has a throwing blade 311a perpendicular to the throwing disc 310a. When the feeder 1000a is working, the throwing disc 310a rotates under the drive of the motor 320a, and the feed particles falling from the vibration disc 210a will be thrown obliquely upward under the high-speed impact of the throwing blade 311a, thereby completing the whole process of feeding and throwing.

[0003] See also Figure 2 The main body of the throwing mechanism 300a is composed of a throwing bin 340a, an upper cover 350a and a throwing disc 310a. The throwing bin 340a is a shell with three closed sides and a bell-shaped opening on one side. A motor 320a is installed at the lower part of the throwing bin 340a, and the throwing disc 310a is fixed on the motor 320a. When working, the throwing disc 310a will rotate driven by the motor 320a. The upper cover 350a is provided with a discharge port 351a on the right side of the throwing disc 310a. When the throwing mechanism 300a is working, the feed particles will pass through the discharge port 351a from the upper discharge mechanism 200a outlet under the action of gravity and fall into the throwing bin 340a. Because the lower side of the discharge port 351a is directly opposite to the rotating throwing disc 310a. Please refer to Figure 3After the feed particles fall into the throwing bin 340a from the discharge port 351a, the throwing disc 310a below rotates counterclockwise at high speed, and the feed particles will be beaten forward by the throwing blades 311a and thrown out from the throwing port 341a in front of the throwing bin 340a, thereby completing the throwing process. This is the working principle of the throwing mechanism 300a commonly used at present.

[0004] See also Figure 4 The throwing plate 310a is composed of a bottom plate 312a, a shaft sleeve 313a and a plurality of throwing blades 311a perpendicular to the bottom plate 312a. The shaft sleeve 313a is used to fix the throwing plate 310a on the motor shaft of the motor 320a, and the throwing blades 311a are used to beat the feed particles falling from above. Figure 5 , since the throwing disc 310a rotates at high speed during operation, and the upper cover 350a is fixed, a gap must be left between the throwing disc 310a and the upper cover 350a, and in order to prevent the feed particles from being stuck between the upper cover 350a and the throwing blades 311a, the height of the gap must be greater than the maximum diameter of the feed particles. When the feed particles fall, since the throwing disc 310a rotates at high speed, the typical speed is 2800 revolutions per minute, and the throwing disc 310a usually has 4 throwing blades 311a perpendicular to the bottom plate 312a, there is a high probability that the feed particles will be cut by the upper edge of the rotating throwing blades 311a when they fall, and thrown obliquely upward, rebound to the upper cover 350a, and further rebounded downward by the upper cover 350a.

[0005] Since the above process may occur multiple times, some feed particles will inevitably be rebounded to the upper cover by the throwing blades during the throwing process. At this time, the feed particles have the maximum speed, and the collision can easily cause the feed particles to be crushed, and the cutting process by the edge of the throwing blades can also cause the feed particles to be crushed. Actual measurements show that the crushing rate for puffed feed is about 5%, while the crushing rate for more easily crushed submerged feed (density greater than water) is as high as 18%. Since feed accounts for 60% to 70% of the cost of the breeding process, a typical breeding pond feeds hundreds of kilograms of feed a day, and the waste and cost increase caused by feed crushing are very significant.

[0006] On the other hand, after the feed is rebounded by the upper cover, it may be refracted downward when leaving the throwing port, which will seriously shorten the throwing distance. An important function of a feeder is to maximize the throwing distance to provide a larger feeding area. Therefore, the refraction of the upper cover will also reduce the feeding area accordingly, reducing the efficiency of the feeder.

[0007] In addition, in the existing throwing mechanism, since there is a large gap between the throwing disc blades and the upper cover, when the throwing disc rotates, the airflow rubs violently between the rotating throwing blades and the stationary upper cover, which greatly increases air resistance and reduces mechanical efficiency. Therefore, a larger power motor is required, which not only increases the cost, but also easily causes the motor to overheat and shut down due to excessive power consumption. Utility Model Content

[0008] The purpose of the implementation mode of the utility model is to provide a throwing mechanism and a feeding machine, aiming to solve the problems that the existing throwing mechanism has many disadvantages.

[0009] In order to solve the above technical problems, the embodiment of the utility model provides a throwing mechanism, comprising:

[0010] An upper cover, wherein the upper cover is provided with a feed inlet, an annular baffle is provided on the lower surface of the upper cover, the upper end of the annular baffle is connected to the feed inlet, and the annular baffle is provided with a discharge port, so that feed particles enter the annular baffle from the feed inlet and then flow out from the discharge port;

[0011] A throwing plate, the throwing plate is rotatable relative to the upper cover along an axis in the up-down direction, the throwing plate includes an annular upper cover, a bottom plate and blades, the annular upper cover is sleeved outside the annular baffle, the annular upper cover and the bottom plate are respectively located at the upper side and the lower side of the discharge port, so that the feed particles flowing out from the discharge port can pass through the gap between the annular upper cover and the bottom plate and then be thrown out, and the blades are arranged in the gap between the annular upper cover and the bottom plate.

[0012] When the throwing mechanism of the utility model is working, the feed particles enter the annular baffle from the feeding port of the upper cover and flow out from the discharging port of the annular baffle. Since the discharging port is located between the annular upper cover and the bottom plate of the throwing disk, the feed particles can only move from the inside to the outside along the radial direction of the throwing disk and be thrown forward under the action of the blades of the throwing disk. Since the discharging port constrains the direction of the feed particles, the feed particles are strictly limited in the gap between the annular upper cover and the bottom plate, and will not be reflected by the throwing bin, thereby significantly reducing the damage of the feed particles caused by multiple reflections; at the same time, since the reflection of the upper cover is avoided, the feed particles will not be reflected downward by the upper cover, thereby avoiding the problem of too short throwing distance of some feed particles due to too low an emission angle; and due to the existence of the annular baffle, the feed particles can only pass through the discharging port with a limited angle, thereby limiting the feed particles to be thrown forward, avoiding the collision of the feed particles with the wall of the throwing bin, and also reducing the damage of the feed particles. The annular baffle also limits the airflow from being sucked in from directions other than the feeding port, thereby significantly reducing the power consumption of the system.

[0013] Preferably, a plurality of blades are arranged at intervals along the rotation direction of the throwing disc.

[0014] Preferably, the blade is an arc-shaped blade, and the blade is gradually bent in a direction opposite to the rotation direction of the throwing plate from the inner edge to the outer edge of the annular upper cover.

[0015] Preferably, the inner end of the blade is flush with the inner edge of the annular upper cover.

[0016] Preferably, the outer end of the blade is flush with the outer edge of the annular upper cover.

[0017] Preferably, the bottom plate is located at the lower side of the annular baffle, and the bottom plate covers the lower end of the annular baffle.

[0018] Preferably, the discharge port passes through the lower end surface of the annular baffle.

[0019] Preferably, a shaft sleeve is provided on the bottom plate, and the shaft sleeve is sleeved outside the transmission shaft of the motor so as to drive the throwing plate to rotate through the motor, and the upper end of the shaft sleeve extends into the annular baffle.

[0020] Preferably, the gap between the annular upper cover and the annular baffle is less than 10 mm.

[0021] Preferably, a guide structure is provided in the annular baffle, and the guide structure is used to guide the feed particles from the feed inlet to the discharge outlet.

[0023] Preferably, part of the throwing plate extends from the throwing port to outside the throwing bin.

[0042] The utility model provides a throwing mechanism, which can be applied to a feeding machine. Figures 6 to 9 A preferred embodiment of the throwing mechanism provided by the utility model is shown.

[0043] See also Figures 6 to 9 In this embodiment, the throwing mechanism 100 includes an upper cover 1 and a throwing tray 3 .

[0044] See also Figures 6 to 9 A feed port 11 is provided on the upper cover 1, and an annular baffle 2 is provided on the lower surface of the upper cover 1. The upper end of the annular baffle 2 is connected to the feed port 11, and an outlet 21 is provided on the annular baffle 2 to allow feed particles to enter the annular baffle 2 from the feed port 11 and then flow out from the outlet 21.

[0045] Specifically, the upper cover 1 is provided in a plate shape, the annular baffle 2 is provided in a cylindrical shape extending in the up-down direction, the upper end surface of the annular baffle 2 is connected to the lower surface of the upper cover 1, so as to seal the upper end of the annular baffle 2 through the upper cover 1, and the discharge port 21 is provided in the area of ​​the upper cover 1 for sealing the upper end of the annular baffle 2, and the discharge port 21 penetrates the upper cover 1 up and down, so that the discharge port 21 is connected to the upper end of the annular baffle 2, so that the feed particles can enter the annular baffle 2 from the feed port 11 of the upper cover 1. The lower end of the annular baffle 2 is provided with a sealing structure, so as to limit the feed particles in the annular baffle 2 from flowing out from the lower end of the annular baffle 2 through the sealing structure, wherein the specific setting method of the sealing structure will be further described below.

[0046] The annular baffle plate 2 is provided with a discharge port 21 penetrating inside and outside, so that the feed particles entering the annular baffle plate 2 from the feed port 11 can flow out from the discharge port 21. Figures 6 to 9 In this embodiment, a guide structure 5 is provided in the annular baffle 2 , and the guide structure 5 is used to guide the feed particles from the feed inlet 11 to the discharge outlet 21 .

[0047] Specifically, the two ends of the guide structure 5 are connected to the feed port 11 and the discharge port 21 respectively, and the feed particles entering the annular baffle 2 from the feed port 11 can slide along the guide structure 5 to the discharge port 21, and finally flow out from the discharge port 21. The specific arrangement of the guide structure 5 is not particularly limited, and the guide structure 5 can be a guide groove, a guide channel or a guide plate, etc.

[0048] Optionally, see Figures 6 to 9 In this embodiment, the feed port 11 and the discharge port 21 are opposite to each other up and down.

[0049] Specifically, a discharge port 21 is provided on the side of the annular baffle 2 deviating from the center of the circle, and a feed port 11 is provided on one end of the upper cover 1 horizontally close to the discharge port 21. The feed port 11 is located directly above the discharge port 21, so that a channel is formed between the upper cover 1 and the annular baffle 2, through which feed particles enter from the top and flow out from the side.

[0050] Optionally, see Figures 6 to 9 In this embodiment, the throwing mechanism 100 also includes a throwing bin 6, which is open upward, and the upper cover 1 covers the opening of the throwing bin 6. The annular baffle 2 is located in the throwing bin 6, and the throwing bin 6 is provided with a throwing port 61.

[0051] Specifically, the shape of the upper cover 1 is usually compatible with the shape of the opening of the throwing bin 6, and the upper cover 1 covers the opening of the throwing bin 6, so that the upper cover 1 and the throwing bin 6 are assembled to form a shell with three closed sides and a trumpet-shaped opening (i.e., the throwing opening 61) on one side.

[0052] The direction of the material throwing port 61 on the throwing bin 6 is horizontal. Similarly, the direction of the material discharge port 21 on the annular baffle 2 is also horizontal. The direction of the material discharge port 21 and the direction of the material throwing port 61 can be the same or different. Figures 6 to 9 In this embodiment, the direction of the discharge port 21 is perpendicular or approximately perpendicular to the direction of the throwing port 61 .

[0053] For example, see Figures 6 to 9 In this embodiment, the ejection port 61 is arranged forward, and the discharge port 21 is arranged rightward.

[0054] See also Figures 6 to 9The throwing plate 3 is rotatable relative to the upper cover 1 along the vertical axis. The throwing plate 3 includes an annular upper cover 31, a bottom plate 32 and blades 33. The annular upper cover 31 is mounted outside the annular baffle 2. The annular upper cover 31 and the bottom plate 32 are respectively located on the upper and lower sides of the discharge port 21, so that the feed particles flowing out from the discharge port 21 can pass through the gap between the annular upper cover 31 and the bottom plate 32 and then be thrown out. The blades 33 are arranged in the gap between the annular upper cover 31 and the bottom plate 32.

[0055] Specifically, the throwing disc 3 is connected to the transmission shaft of the motor 4, and the motor 4 can drive the throwing disc 3 to rotate along the vertical axis.

[0056] Optionally, see Figures 6 to 9 In this embodiment, a shaft sleeve 34 is provided on the bottom plate 32 , and the shaft sleeve 34 is sleeved outside the transmission shaft of the motor 4 to drive the throwing plate 3 to rotate through the motor 4 , and the upper end of the shaft sleeve 34 extends into the annular baffle 2 .

[0057] Specifically, the sleeve 34 is provided with a through hole for the transmission shaft of the motor 4 to pass through, so as to fix the transmission shaft of the motor 4 with the throwing disc 3. The throwing disc 3 is composed of an annular upper cover 31, a bottom plate 32, blades 33 and a sleeve 34. The annular upper cover 31, the bottom plate 32, the blades 33 and the sleeve 34 are rigidly connected to each other as a whole, wherein the annular upper cover 31 is an annular disc structure, the annular upper cover 31 is coaxial with the throwing disc 3, and the inner diameter of the annular upper cover 31 is slightly larger than the outer diameter of the annular baffle 2. A plurality of blades 33 are arranged between the annular upper cover 31 and the bottom plate 32, the bottom plate 32 is a disc structure, and the outer diameter of the bottom plate 32 is usually equal to or approximately equal to the outer diameter of the annular upper cover 31.

[0058] As described above, the inner diameter of the annular upper cover 31 is slightly larger than the outer diameter of the annular baffle 2, so that a gap is formed between the annular upper cover 31 and the annular baffle 2, and the gap between the annular upper cover 31 and the annular baffle 2 is half of the difference between the inner diameter of the annular upper cover 31 and the outer diameter of the annular baffle 2. The gap between the annular upper cover 31 and the annular baffle 2 is usually smaller than the maximum diameter of the feed particles, thereby preventing the feed particles from passing through the annular upper cover 31 and the annular baffle 2. Optionally, please refer to Figures 6 to 9 In this embodiment, the gap between the annular upper cover 31 and the annular baffle 2 is less than 10 mm.

[0059] The feed particles enter the annular baffle 2 from the feed inlet 11 of the upper cover 1 and flow out from the discharge port 21 of the annular baffle 2. Since the discharge port 21 is located between the annular upper cover 31 and the bottom plate 32 of the throwing disc 3, the feed particles can only move from the inside to the outside along the radial direction of the throwing disc 3 and are thrown forward under the action of the blades 33 of the throwing disc 3. Since the discharge port 21 constrains the direction of the feed particles, the feed particles are strictly confined to the gap between the annular upper cover 31 and the bottom plate 32 and will not be reflected by the throwing bin 6, thereby significantly reducing the damage of the feed particles due to multiple reflections.

[0060] The blades 33 can beat the feed particles between the annular upper cover 31 and the bottom plate 32. Usually, a plurality of blades 33 are arranged at intervals along the rotation direction of the throwing plate 3. Figures 6 to 9 In this embodiment, four blades 33 are evenly spaced along the rotation direction of the throwing disc 3 .

[0061] The specific shape of the blade 33 is not particularly limited. Figures 6 to 9 In the present embodiment, the blade 33 is an arc-shaped blade, and the blade 33 is gradually bent in the direction opposite to the rotation direction of the throwing plate 3 from the inner edge to the outer edge of the annular upper cover 31.

[0062] Specifically, the upper end of the blade 33 is connected to the lower surface of the annular upper cover 31, the lower end of the blade 33 is connected to the upper surface of the bottom plate 32, and the blade 33 is perpendicular to the bottom plate 32. The projection of the blade 33 on the bottom plate 32 is an arc, and the arc bending direction is from the center of the bottom plate 32 outward and opposite to the rotation direction of the throwing plate 3. The blade 33 is set as an arc blade, which can further reduce the impact force acting on the feed particles, thereby further reducing the breakage of the feed particles.

[0063] Optionally, see Figures 6 to 9 In this embodiment, the inner end of the blade 33 is flush with the inner edge of the annular upper cover 31. In this way, during the rotation of the throwing plate 3, it is not easy for the blade 33 to interfere with the annular baffle 2.

[0064] Optionally, see Figures 6 to 9 In this embodiment, the outer end of the blade 33 is flush with the outer edge of the annular upper cover 31. In this way, during the rotation of the throwing plate 3, it is not easy for the blade 33 to interfere with the inner wall of the throwing bin 6.

[0065] See also Figures 6 to 9The gap between the annular upper cover 31 and the bottom plate 32 is horizontally opposite to the throwing port 61 on the throwing bin 6, so that the feed particles thrown out by the throwing disc 3 can be thrown out of the throwing bin 6 from the throwing port 61. The throwing disc 3 can be completely located in the throwing bin 6; the throwing disc 3 can also be partially located in the throwing bin 6 and the other part is located outside the throwing bin 6.

[0066] Optionally, see Figures 6 to 9 In this embodiment, part of the throwing plate 3 extends from the throwing port 61 to the outside of the throwing bin 6. The front end of the throwing plate 3 extends from the throwing port 61 to the outside of the throwing bin 6, which is beneficial to avoid collision between feed particles and the throwing bin wall.

[0067] When the throwing mechanism 100 of the utility model is working, the feed particles enter the annular baffle 2 from the feed inlet 11 of the upper cover 1 and flow out from the discharge port 21 of the annular baffle 2. Since the discharge port 21 is located between the annular upper cover 31 and the bottom plate 32 of the throwing plate 3, the feed particles can only move from the inside to the outside along the radial direction of the throwing plate 3 and are thrown forward under the action of the blades 33 of the throwing plate 3. Since the discharge port 21 constrains the direction of the feed particles, the feed particles are strictly confined to the gap between the annular upper cover 31 and the bottom plate 32 and will not be reflected by the throwing bin 6, thereby significantly reducing The feed particles are damaged due to multiple reflections. At the same time, since the reflection of the upper cover 1 is avoided, the feed particles will not be reflected downward by the upper cover 1, thereby avoiding the problem of too short a throwing distance of some feed particles due to too low an emission angle. In addition, due to the presence of the annular baffle 2, the feed particles can only pass through the discharge port 21 at a limited angle, thereby limiting the feed particles to be thrown forward, avoiding the collision between the feed particles and the wall of the throwing bin, and also reducing the damage of the feed particles. The annular baffle 2 also limits the airflow from being sucked in from directions other than the feed port 11, thereby significantly reducing the power consumption of the system.

[0068] As described above, a covering structure is provided at the lower end of the annular baffle 2, and the covering structure may be a covering plate provided at the lower end of the annular baffle 2; the covering structure may also be the bottom wall of the throwing bin 6 or the bottom plate 32 of the throwing tray 3, etc.

[0069] Optionally, see Figures 6 to 9 In this embodiment, the bottom plate 32 is located at the lower side of the annular baffle 2, and the bottom plate 32 covers the lower end of the annular baffle 2. That is, the bottom plate 32 forms a covering structure, and the lower end of the annular baffle 2 is covered by the middle of the bottom plate 32, so that the feed particles in the annular baffle 2 cannot flow out from between the bottom plate 32 and the lower end of the annular baffle 2, so that the feed particles in the annular baffle 2 can only flow out from the discharge port 21.

[0070] A discharge port 21 is provided inside and outside the annular baffle 2. The discharge port 21 can be located in the middle of the annular baffle 2, that is, the discharge port 21 does not penetrate the upper end surface and the lower end surface of the annular baffle 2; the discharge port 21 can also be located in the upper part of the annular baffle 2, that is, the discharge port 21 penetrates the upper end surface of the annular baffle 2, and the discharge port 21 does not penetrate the lower end surface of the annular baffle 2; the discharge port 21 can also be located in the lower part of the annular baffle 2, that is, the discharge port 21 does not penetrate the upper end surface of the annular baffle 2, and the discharge port 21 penetrates the lower end surface of the annular baffle 2.

[0071] Optionally, see Figures 6 to 9 In this embodiment, the discharge port 21 passes through the lower end surface of the annular baffle 2 , so that the upper surface of the bottom plate 32 is flush with the lower edge of the discharge port 21 .

[0072] Optionally, see Figures 6 to 9 In this embodiment, the annular upper cover 31 is close to the upper edge of the discharge port 21 , so that the lower surface of the annular upper cover 31 is flush with the upper edge of the discharge port 21 .

[0073] Compared with the existing throwing mechanism, the power consumption of the throwing mechanism 100 can be reduced by more than 50%, and the throwing mechanism 100 can reduce the feed breakage rate by more than 60%; and the appearance of the throwing mechanism 100 is similar to that of the existing throwing mechanism, and can be directly replaced and used without modifying the feeder. The throwing mechanism 100 has the advantages of low application cost, small feed loss and low power consumption.

[0074] The utility model also provides a feeding machine, which comprises 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.

[0075] 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.
