Description

TECHNICAL FIELD

[0001] The application relates to the technical field of feeding machines, in particular to a large-scale double-outlet shrimp feed feeding machine. BACKGROUND

[0002] At present, when feeding feed, the feed is directly thrown from a high place into a fishery, and the impact of the feed particles on the water surface can cause surface damage.

[0003] In order to reduce the labor intensity of fishermen, a vibrating automatic feeding machine is used for a larger fishery, and the feed is placed in the water, and local accumulation occurs in the process of continuous vibration of the feed, and collision and wear exist between the feed particles and the side wall of the feeding machine.

[0004] In addition, when the feeding amount is large and the feeding needs to be performed at regular time intervals, manual feeding is not easy, and most of the time, a feeding machine is used for feeding, and since the storage warehouse and the feeding machine are a certain distance apart, in order to make the nutrition of the feeding feed more comprehensive, the artificial mixed formula feed can be transported to the storage warehouse of the feeding machine only after the artificial mixed formula feed is mixed, so that the two kinds of feed can be proportioned and fed, but in this way, the feed is mixed in advance and then transported to the storage of the feeding machine, and the feed is exposed to the outdoor environment for a long time, is easy to be damp, further damages the surface of the feed particles, and the artificial repeated operation is too laborious, and the continuity of the whole process is not strong.

[0005] The surface of the feed is the first barrier against moisture penetration, and once damaged, water will quickly enter the inside of the feed particles, thereby dissolving the nutrients, and causing the feed to dissolve too early. When feeding shrimps in a fishery, because shrimps are food-holding animals, they will hold the feed particles with their chelicerae and feed for a long time in the water, and when the surface of the feed is damaged, it will quickly disintegrate after entering the water, thereby causing the shrimps to be unable to effectively feed. SUMMARY

[0006] In order to overcome the technical defects in the above background art, the application provides a large-scale double-outlet shrimp feed feeding machine, which can improve the convenience of feed feeding, reduce the degree of manual intervention, and reduce the damage to the surface of the feed during feeding.

[0007] The large-scale double-outlet shrimp feed feeding machine provided by the application adopts the following technical scheme: A large-scale double-outlet shrimp feed feeding machine, a machine shell, a discharge port is formed through the top wall of the machine shell; A discharge hopper is arranged in the interior of the machine shell, the top edge of the discharge hopper is connected with the inner wall of the machine shell, and the two are welded and reinforced; a ton bag for temporarily storing feed is connected with the discharge port; a partition plate is detachably and vertically installed in the middle of the discharge hopper, and the discharge hopper is divided into two storage warehouses by the partition plate; The impeller frame is vertically aligned with the two storage bins, and includes an inlet and an outlet, with the inlet aligned with the storage bin adjacent to it and the outlet aligned with the storage bin adjacent to it. The impeller is rotationally connected to the middle of the impeller frame and drives the feed inside the impeller frame to the outside of the shell.

In the present application, the ton bag temporarily stores the feed, and the storage bin of the discharge hopper stores the feed, which has good feed feeding sealing, and then the rotation of the impeller realizes the feeding of the feed from the inlet to the outlet, which can also avoid local accumulation and collision and wear of the feed during vibration. Through the double storage bin structure cooperating with the independent impeller system, synchronous or time-sharing feeding of two kinds of feed can be realized, the nutritional needs of shrimp at different growth stages can be met, the convenience of feed feeding can be improved, the degree of manual intervention can be reduced, thereby reducing the labor intensity of repeated manual operation.

The accuracy of feed feeding is improved, and the feeding ratio and feeding time of the two types of feed can be flexibly adjusted according to the actual feeding demand of shrimps, thereby further meeting the nutritional demand of shrimps at different growth stages, and the good sealing effect is achieved when no feed is fed to avoid feed from getting wet.

Meanwhile, the conveying mode of the fan reduces mechanical extrusion and damage of the feed during conveying, thereby ensuring the integrity of the feed particles.

[0019] Preferably, a tapered material guide head is detachably installed at the end of the material spraying port, and the diameter of the material guide head gradually narrows from the end close to the material spraying port to the outside.

[0020] By adopting the above technical scheme, the design of the tapered material guide head makes the feed form a more concentrated material flow when being sprayed, and reduces the scattering and waste of the feed. The gradual narrowing design of the diameter of the material guide head can also adjust the outlet size of the material spraying port according to actual needs, so as to control the spraying speed and range of the feed.

DETAILED DESCRIPTION

[0037] The following will be described in detail in combination with the accompanying Figures 1-8 The present application is further described in detail.

[0038] The embodiment of the present application discloses a large-scale double-outlet shrimp material feeding machine.

[0039] Referring to Figure 1 and Figure 2 , a large-scale double-outlet shrimp material feeding machine comprises a machine shell 1, the machine shell 1 comprises a first protective shell 11 and a second protective shell 12, the first protective shell 11 is fixed above the second protective shell 12, the first protective shell 11 is a box type structure completely enclosed on all sides, a blanking cover plate 111 that can be opened by lifting is arranged on the top of the first protective shell 11, and a blanking port 112 for active blanking is also arranged, specifically, a user can put the feed into the machine shell 1 through the blanking cover plate 111 opened by lifting or realize self-blanking by assembling the port of a ton bag with the blanking port 112.

[0040] The second protective shell 12 comprises a protective frame 21, a visualizing baffle 22 and a connecting piece 23, the protective frame 21 is provided with a skirt near one side of the inside of the second protective shell 12, the visualizing baffle 22 is connected with the protective frame 21 through the connecting piece 23, and the visualizing baffle 22 is assembled with the protective frame 21 through the connecting piece 23, so that a box type structure consistent with the first protective shell 11 in shape and size is obtained.

[0041] Specifically, referring to Figure 3 and Figure 4 , the protective frame 21 provides main support, the first protective frame is welded at the top of the protective frame 21, the protective frame 21 at least comprises four columns 221, the four columns 221 are arranged at four corners and are vertically arranged, the column 221 is hollow inside to avoid structural cracks caused by stress concentration, a skirt is arranged on each of two adjacent sides of each column 221, the skirt presents an L-shaped structure, and a sealing pad layer such as a rubber pad can be additionally provided on the outer side, the visualizing baffle is arranged outside the skirt and closely attached to each other, the visualizing baffle 22 can adopt a transparent plastic plate to facilitate the operator to observe the internal condition, and the skirt can play a protective and sealing role.

[0042] Further, the connecting piece 23 comprises a plug 231, a first plug-in part 232, a hook part 233 and a second plug-in part 234, wherein the first plug-in part 232 and the second plug-in part 234 are respectively fixed on the two opposite sides of the plug 231, the plug 231 presents a T-shaped structure, the first plug-in part 232 is a rectangular block, the hook part 233 is fixed on one end of the first plug-in part 232 away from the plug 231, and the side surfaces of the hook part 233 and the second plug-in part 234 are beveled.

[0043] In the process of installing the visual baffle 22 and the stand 221, the first plug-in part 232 is first plugged into the plug-in hole on the side of the stand 221 until the hook part 233 is hooked with the internal structure of the stand 221, then the plug 231 part is embedded with the visual baffle 22, and the second plug-in part 234 is plugged into the visual baffle 22 close to it. In this installation process, the bevel is helpful to guide the first plug-in part 232 and the second plug-in part 234 to smoothly enter the corresponding plug-in position, improve the installation efficiency, and the stable and reliable connection mode cooperates with the setting of the skirt to block the water in the rainy day, and the water can flow down along the outer edge of the skirt, and will not penetrate into the second protective shell 12, effectively protecting the dry environment of the internal equipment, preventing electrical failure or feed deterioration due to dampness. Moreover, when the visual baffle 22 needs to be disassembled for equipment maintenance or cleaning, only the second plug-in part 234 is pulled out, and then the first plug-in part 232 is pulled out from the plug-in hole by pulling the hook part 233, so that the visual baffle 22 can be easily taken off, the whole process is simple and convenient, and the maintainability of the equipment is greatly improved. In actual use, the operator can observe the running condition of the impeller 5 and the conveying state of the feed in the pipe 42 through the visual baffle 22, and once an abnormality is found, the machine can be stopped for inspection in time to avoid further expansion of the fault and ensure the stable operation of the feeder, thereby providing reliable feed feeding guarantee for shrimp culture.

[0044] The bottom of the shell 1 is provided with a supporting frame 7, which at least includes a supporting plate 71 and a top column, one end of the top column is fixed with the bottom of the shell 1, and the other end is fixed with the top surface of the supporting plate 71, and the three are assembled to present an I-shaped structure, so that a rat gap 72 is left between the shell 1 and the supporting plate 71. The design of the supporting frame 7 provides stable support for the shell 1, and the combined structure of the supporting plate 71 and the top column ensures the stability of the shell 1. Since the rat gap 72 is left between the shell 1 and the supporting plate 71, the damage of mice and other small animals to the equipment and the pollution of the feed are effectively prevented, and the upward infiltration of water at the bottom is also avoided, thereby ensuring the normal operation of the equipment and the safety of the feed.

[0045] Referring to Figure 2 and Figure 5Inside the shell 1, the lower hopper 3 is placed in the first protective shell 11, the top edge of which is in close contact with the inner wall of the first protective shell 11 and is reinforced by welding, ensuring the stability of the lower hopper 3 during use. The lower hopper 3 is a hollow ladder structure, including a hopper plate, which is inclined from the outer wall of the first protective shell 11 to the horizontal center line of the second protective shell 12. This inclined design allows the feed falling from the lower cover plate 111 or the lower discharge port 112 to smoothly slide into the lower hopper 3. A partition is vertically installed in the middle of the lower hopper 3, which divides the lower hopper 3 into two storage compartments, allowing the simultaneous storage of two different proportions of feed to meet the nutritional needs of shrimp at different growth stages.

[0046] Further, the impeller frame 4 has two, which are vertically aligned with the two storage compartments. In the case of one impeller frame 4, the impeller frame 4 is circular in structure and has a smooth inner wall, which includes an inlet and an outlet. The inlet is aligned with the storage compartment adjacent to it, and the outlet is connected to the subsequent pipe 42.

[0047] Referring to Figure 5 , Figure 6 , Figure 7 The impeller 5 is rotationally connected to the middle of the impeller frame 4, which can be driven by a motor to rotate the shaft in the middle of the impeller 5. The impeller 5 includes a plurality of blades 52 distributed equidistantly along the outer wall of the hub 51. The blades 52 are required to have good stiffness and wear resistance. There is a gap between the edges of the blades 52 and the inner wall of the impeller frame 4 to avoid direct friction between the blades 52 and the inner wall of the impeller frame 4. An elastic pad 53 is detachably installed on the side surface of each blade 52. The elastic pad 53 is made of a wear-resistant material with certain elasticity, such as rubber.

[0048] The inlet and outlet of the impeller frame 4 are oppositely arranged, and the shape and size of the inlet and outlet are consistent. The included angle between two adjacent blades 52 is between 15-45°. The elastic pad 53 on one blade 52 and the elastic pad 53 on the next adjacent blade 52 can block the inlet or outlet, wherein the next adjacent blade 52 is a symmetric blade 52 with the adjacent blade 52 as the axis of symmetry.

[0049] In the present application, when the included angle between two adjacent blades 52 is 15-45°, the elastic pad 53 on one blade 52 can accurately block the feed inlet or discharge outlet on the next adjacent blade 52, ensuring the accuracy of the mutual cooperation of the elastic pads 53 during rotation, effectively blocking the feed inlet or discharge outlet, and avoiding material leakage. Preferably, the included angle between two adjacent blades 52 is 30° or 45°, and the force on the blade 52 during rotation is relatively balanced, avoiding excessive or insufficient local stress caused by unreasonable included angle. For example, if the included angle is too small, less than 15°, the space between the blades 52 is narrow, and the material is prone to congestion when passing through, reducing the conveying efficiency and causing the material to accumulate near the feed inlet, affecting the entire feeding process; if the included angle is too large, more than 45°, the pushing effect of the blade 52 on the material will be weakened, the material will stay in the impeller 5 machine for a longer time, and it cannot be timely transported from the feed inlet to the discharge outlet, causing the impeller 5 machine to vibrate during operation, which will damage the equipment parts over a long period of time, reduce the service life of the equipment, and increase the maintenance cost.

[0050] The presence of the elastic pad 53 can play a buffering role during the rotation of the impeller 5. When the blade 52 is close to the inner wall of the impeller frame 4, the elastic pad 53 contacts the inner wall first, reducing the direct collision between the blade 52 and the inner wall of the impeller frame 4, thereby reducing equipment wear and noise during operation. On the other hand, when the elastic pad 53 is worn to a certain extent, it can be replaced individually without replacing the entire impeller 5, greatly reducing the maintenance cost of the equipment. Moreover, the end of the elastic pad 53 protrudes beyond the edge of the blade 52, and is in interference fit with the inner wall of the impeller frame 4, which can form a good sealing effect, preventing feed from leaking from the gap between the blade 52 and the inner wall of the impeller frame 4 during transportation, and ensuring that the feed can be accurately transported from the feed inlet to the discharge outlet.

[0051] The present application cooperates with the specific included angle between adjacent blades 52 and the blocking effect of the elastic pad 53. When the impeller 5 rotates to a specific position, the feed inlet or discharge outlet is effectively blocked, thereby accurately controlling the feeding time and flow of the feed. Not only does it improve the accuracy of feed feeding, but it also flexibly adjusts the feeding ratio and feeding time of the two types of feed according to the actual feeding needs of shrimps, further meets the nutritional needs of shrimps at different growth stages, and has good sealing effect when not feeding, avoiding feed from getting wet, and forming a gate-like opening and closing effect.

[0052] Further, with reference to Figure 5 and Figure 8The bottom of the impeller frame 4 is provided with a connecting hopper, a fan 41 and a material pipe 42, the top end of the connecting hopper is communicated with the discharge port of the impeller frame 4, the other end is communicated with the wall of the material pipe 42, the output end of the fan 41 is connected with the end of the material pipe 42. The end of the material pipe 42 away from the fan 41 is provided with two spray ports 61 and a double spray port joint 6 of a connecting pipe 62, the double spray port joint 6 is in a T-shaped structure, the connecting pipe 62 is communicated between the two spray ports 61, the other end of the connecting pipe 62 is detachably connected with the material pipe 42, the two spray ports 61 are communicated and in a Z-shaped structure, and all the inflection points are rounded.

[0053] The T-shaped structure of the double spray port joint 6 forms a tee joint, the fan 41 divides the feed in the material pipe 42 into two paths to realize flow splitting, and makes the feed enter the spray ports 61 from the material pipe 42, the two spray ports 61 are communicated and in a Z-shaped structure instead of a straight line structure, in this way, the spray ports 61 and the connecting pipe 62 have an included angle, which is equivalent to an inclined flow channel, the included angle is between 120°-150°, so that the feed can change direction during spraying, and can better slide along the inclined flow channel under the action of the wind energy provided by the fan 41, so that the feed flows more smoothly, and the possibility of clogging and material accumulation is reduced. Since the straight line structure lacks direction change, the feed is easy to accumulate near the spray ports 61, the structure design of the application can cooperate with the wind energy to push the feed, and form good cooperation with the flow channel, so that the feed receives assistance during discharging, improves the material accumulation of the straight line structure, and has better flow effect. At the same time, all the inflection points are rounded, which further reduces the resistance of the feed when flowing through the inflection points, avoids the crushing and dust of the feed due to sharp turns, ensures the integrity and quality of the feed, and thus provides better feed for shrimps.

[0054] In the application, a tapered guide head 63 is detachably installed at the end of the spray port 61, and the diameter of the guide head 63 gradually narrows from the end close to the spray port 61 to the outside. The design of the tapered guide head 63 makes the feed form a more concentrated flow when sprayed, reducing the scattering and waste of the feed. Users can also adjust the outlet size of the spray port 61 according to actual needs, so as to control the spraying speed and range of the feed. Compared with the traditional feeding method, the application improves the feeding efficiency and quality, and reduces the breeding cost.

[0055] The above are preferred embodiments of the application, which are only an explanation of the application and do not limit the protection scope of the application, therefore: all equivalent changes made according to the structure, shape, principle of the application shall be covered within the protection scope of the application.
