Description

Technical Field

[0001] The utility model relates to the technical field of fishery breeding, and more specifically, to a bait dispenser. Background Art

[0002] my country's aquaculture industry is developing rapidly, and the scale of fishery farming is increasing. For larger farms, it is usually necessary to distribute feed according to different breeding areas and different types of fish. The traditional manual distribution method has a low level of automation, high labor intensity and low efficiency.

[0003] Although feeding machines are used in aquaculture to automatically feed fish to improve the efficiency of aquaculture, the existing feeding machines can only feed one fish pond at a time. When it is necessary to feed several fish ponds, it is difficult to meet the feeding needs and the feeding time is difficult to manage. If several fish ponds are to be fed at the same time, it is necessary to equip several material conveying devices and several feeding machines, which greatly increases the cost of breeding. In view of the problem that a single feed port corresponds to each other, some improvement schemes have been proposed. For example, patent CN219182470U provides a feeding device based on one feed port for feeding multiple discharge ports. However, the connection mechanism used to switch the feed port to connect with different discharge ports includes two parallel rails, a moving seat, a driving motor, a pulley, a rolling screw and other mechanical components. The overall structure is complex and difficult to miniaturize. The operating reliability and stability are difficult to guarantee. In addition, the distance between the discharge port and the feed port is too large, and an additional pipeline needs to be set for connection. There is a greater risk of leakage and liquid leakage, which undoubtedly increases the difficulty of maintaining the device.

[0004] In view of this, it is necessary to design a bait dispenser to solve the many problems of the existing feeding device, such as complex mechanical structure, large size, and difficult maintenance. Utility Model Content

[0005] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a bait dispenser for solving the problems of complicated structure and difficult maintenance of the existing bait dispenser.

[0006] The technical solution adopted by the utility model is to provide a bait dispenser, including a base, and a discharge assembly and a reciprocating drive mechanism arranged on the base; the discharge assembly includes a discharge plate with at least two discharge ports, the discharge plate is arranged on one side in the width direction of the base, and the discharge ports are spaced apart along the length direction of the base; a connecting valve is connected to the driving end of the reciprocating drive mechanism, and gaps are left between the connecting valve and the discharge plate, and between the connecting valve and the base, a feed channel is penetrated by the connecting valve, and the extension direction of the feed channel is consistent with the width direction of the base, and the reciprocating drive mechanism is configured to reciprocately drive the connecting valve along the length direction of the base to connect the feed channel with different discharge ports.

[0007] This solution only requires connecting the feed pipe to the feed channel of the connecting valve, and then reciprocatingly driving the connecting valve to dock with different discharge ports through the reciprocating drive mechanism, so as to achieve the purpose of distributing bait to multiple different discharge ports through one feed channel. The bait distributor of this solution has a simple structure, which greatly reduces the difficulty of loading and unloading and maintenance, and is conducive to miniaturization design. At the same time, since there are few accessories involved, it is helpful to reliably assemble the various mechanisms, and improve the reliability and stability of the bait distributor during operation. In addition, the connecting valve of this solution has a gap with the discharge plate and the base, which can prevent the connecting valve from being affected by friction resistance during the reciprocating motion to dock with different discharge ports, ensuring that the process of switching the discharge ports is reliable and smooth.

[0008] Furthermore, the width of the gap between the connecting valve and the discharge plate is ≤0.04 mm.

[0009] The gap width of this solution can not only avoid friction resistance between the connecting valve and the discharge plate during reciprocating motion, but also prevent leakage of materials transported to the discharge port by the connecting valve due to excessive gap.

[0010] Furthermore, the reciprocating drive mechanism is a cylinder device or a push rod device.

[0011] The scheme adopts a cylinder device or a push rod device to simplify the structure of the reciprocating drive mechanism, which helps to solve the problem of complicated structure and difficult maintenance of the bait dispenser.

[0012] Furthermore, it is characterized in that a feed pipe is also provided, and the feed pipe is connected to the feed channel of the connecting valve from a side away from the discharge plate.

[0013] This solution adds a feed pipe to facilitate reliable connection with an external feed pipe through the feed pipe, thereby reducing the chance of bait leakage from the feed end. In addition, the feed pipe is pre-connected with the connecting valve to simplify the subsequent steps of connecting the feed pipe to the connecting valve, thereby improving operating efficiency.

[0014] Furthermore, a connecting valve rear baffle is provided, which is arranged on a base opposite to the discharge plate and leaves a gap with the connecting valve. The connecting valve rear baffle is provided with a hollow structure for passing the feed pipe, and the width of the hollow structure corresponding to the length direction of the base is not less than the maximum distance between the discharge ports on both sides.

[0015] The rear baffle of the connecting valve cooperates with the discharge plate to limit the space in the front and rear directions of the connecting valve to a certain extent, which can prevent the connecting valve from shifting forward and backward when it reciprocates, so as to maintain a stable gap width between the connecting valve and the discharge plate, and avoid leakage caused by excessive gap. In addition, the space enclosed by the rear baffle of the connecting valve, the base, and the discharge plate can protect the connecting valve.

[0016] Furthermore, a connecting valve upper baffle is provided, and the connecting valve upper baffle is connected to the upper part of the discharge plate and a gap is left between the connecting valve and the connecting valve.

[0017] The baffle plate on the connecting valve of this scheme cooperates with the base and the discharge plate to limit the space in the upper and lower directions of the connecting valve to a certain extent, which can prevent the connecting valve from having excessive displacement in the upper and lower directions during the reciprocating motion, and help avoid the phenomenon of inaccurate docking between the connecting valve and the discharge port.

[0018] Furthermore, a covering component is provided, and the covering component is used to cover the part of the hollow structure that is not blocked by the connecting valve.

[0019] The covering component of the present invention can prevent external interference objects from entering the space where the connecting valve is located through the hollow structure, thereby enhancing the protective effect on the connecting valve.

[0020] Furthermore, the covering component is a pair of covering baffles, and the covering baffles are respectively connected to two sides of the connecting valve corresponding to the length direction of the base.

[0021] The covering baffle of the present invention can reciprocate with the connecting valve to automatically cover the hollow structure. In addition, the covering baffle has a simple structure, which helps to make the overall structure of the bait dispenser lighter and reduce the difficulty of maintenance.

[0022] Furthermore, a common covering area of ​​any of the covering baffles and the connecting valve is not less than an area of ​​the hollow structure.

[0023] This solution uses the connecting valve to occupy the space in the hollow structure, and combined with the covering area of ​​the covering baffle, it can achieve complete covering of the hollow structure, thereby protecting the connecting valve and the internal space between the connecting valve and the discharge plate.

[0024] Furthermore, the covering baffles are provided with a gap between the inner surface of the baffle behind the connecting valve.

[0025] This solution can avoid friction resistance between the covering baffle and the rear baffle of the connecting valve during the reciprocating motion of the connecting valve by setting a gap, thereby ensuring the reliability and stability of the connecting valve switching and connecting the discharge port.

[0026] Furthermore, a protective cover assembly is provided, and the protective cover assembly is used to cover the reciprocating drive mechanism and the connecting valve.

[0027] Furthermore, a plurality of position sensors electrically connected to the reciprocating drive mechanism are provided, and the position sensors correspond one-to-one to the positions of the discharge ports.

[0028] Compared with the prior art, the beneficial effects of the utility model are as follows: 1) the connecting valve is directly driven back and forth by a push rod or a cylinder, which greatly simplifies the mechanical structure of the connecting valve when switching to connect different discharge ports, reduces the difficulty of loading and unloading and maintenance, improves the operational stability and reliability, and facilitates the miniaturization of the bait dispenser to adapt to more usage scenarios; 2) by integrating the feed pipe directly with the connecting valve, the reciprocating drive mechanism drives the connecting valve to directly link the feed pipe to switch to connect different discharge ports, which can avoid adding additional pipelines between the feed pipe and the connecting valve, and simplify the overall space of the bait dispenser; 3) the limiting space formed by connecting the discharge plate, the connecting valve upper baffle, the connecting valve rear baffle and the base in sequence can protect the connecting valve, and can also limit the deviation amplitude of the reciprocating motion of the connecting valve to a certain extent, thereby improving the accuracy of the connecting valve in connecting different discharge ports.

DETAILED DESCRIPTION

[0040] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0041] Example 1

[0042] like Figure 1-3 As shown, this embodiment provides a bait dispenser, including a base 1, and a discharge assembly and a reciprocating drive mechanism arranged on the base 1; the discharge assembly includes a discharge plate 2 with at least two discharge ports 21, the discharge plate 2 is arranged on one side in the width direction of the base 1, and the discharge ports 21 are spaced apart along the length direction of the base 1; a connecting valve 4 is connected to the driving end of the reciprocating drive mechanism, in order to avoid friction resistance of the connecting valve during reciprocating motion, gaps are left between the connecting valve 4 and the discharge plate 2, and between the connecting valve 4 and the base 1, a feed channel 41 is opened through the connecting valve 4, and the extension direction of the feed channel 41 is consistent with the width direction of the base 1, and the reciprocating drive mechanism is configured to reciprocately drive the connecting valve 4 along the length direction of the base 1 so that the feed channel 41 is connected with different discharge ports 21. During implementation, in order to facilitate connection with the external output pipe, the discharge port 21 is also connected to the discharge pipe 22. In order to improve the connection strength, the discharge pipe 22 is connected to the discharge port 21 through a flange. In order to avoid air leakage and material leakage, sealant is further applied between the discharge port 21, the flange and the discharge pipe 22.

[0043] In specific implementation, in order to simplify the mechanical structure of the reciprocating drive mechanism, the present embodiment adopts the cylinder device 3 to reciprocately drive the connecting valve 4. In implementation, one end of the cylinder device 3 is fixed on the base 1 through the mounting seat. Specifically, in order to reduce the size of the base 1, one end of the cylinder device 3 can be fixed to the end of one side of the base 1, and the push rod component 31 of the cylinder device 3 with a certain length is extended to the other end in the length direction of the base 1. At this time, the discharge ports 21 on the discharge plate 2 are distributed at intervals corresponding to the extension direction of the push rod component 31. When the push rod component 31 reciprocates to drive the connecting valve 4, the feed channel 41 on the connecting valve 4 can be docked with different discharge ports 21, thereby forming a passage between the feed end of the feed channel 41 and the discharge port 21. In some other embodiments, other types of push rod devices can also be used to drive the connecting valve 4.

[0044] In order to reliably connect with the external feed pipe, a feed pipe 42 can be connected to the feed end of the feed channel 41. The feed pipe 42 has a certain length, and the external feed pipe can be directly sleeved on the feed pipe 42 for stable connection. Specifically, in order to improve the connection strength, the feed pipe 42 is installed on the connecting valve 4 through a flange. In order to prevent air leakage and material leakage, a sealant is further applied between the feed pipe 42, the flange, and the connecting valve 4.

[0045] In addition, in a preferred embodiment, the gap width between the connecting valve 4 and the discharge plate 2 is set to ≤0.04mm in this embodiment, which is sufficient to avoid friction resistance between the connecting valve 4 and the discharge plate 2 during reciprocating motion. At the same time, since the bait has a certain size, this gap width is sufficient to avoid leakage of the material transported by the connecting valve 4 to the discharge port 21.

[0046] When the bait dispenser of this embodiment is specifically set up, refer to Figure 1 , Figure 3 , taking the setting of two discharge ports 21 as an example, for the selection of the cylinder or other push rod device, it is only necessary to adjust or select the telescopic range of the push rod component 31 to be sufficient to cover the spacing between the two discharge ports 21. For example, when the push rod component 31 is retracted to the limit position, the feed channel 41 of the connecting valve 4 is just docked with the discharge port 21 close to the cylinder side, and when the push rod component 31 is extended to the limit position, it is just docked with the discharge port 21 far from the cylinder side. In this way, one feed channel 41 can be freely switched and connected with two discharge ports 21. Similarly, when there are more than two discharge ports 21, the telescopic range of the push rod component 31 is adjusted or selected to be sufficient to cover the spacing between multiple discharge ports 21, and the push rod component 31 has multiple gears corresponding to the number of discharge ports 21. In this way, one feed channel 41 can be freely switched and connected with multiple discharge ports 21.

[0047] When doing specific work, Figure 1 , Figure 2 To understand, it is only necessary to connect the external feed pipe to the feed pipe 42, and then reciprocate the connecting valve 4 through the cylinder device 3 to dock with any one of the outlets 21, and then the feed pipe starts to transport the bait, and the bait passes through the feed pipe 42, the feed channel 41 of the connecting valve 4, the outlet 21, the outlet pipe 22 in turn, and finally the bait can be transported to a preset place through the external output pipe. By reciprocatingly driving the connecting valve 4 to dock with different outlets 21, the purpose of distributing bait to multiple outlets 21 through one feed port can be achieved. The bait dispenser of this embodiment has a simple structure, greatly reduces the difficulty of loading and unloading and maintenance, and is conducive to miniaturized design. At the same time, due to the small number of accessories involved, it is helpful to reliably assemble the various mechanisms, and improve the reliability and stability of the bait dispenser during operation.

[0048] Example 2

[0049] like Figure 4-7 As shown, based on the scheme of Example 1, this embodiment is further provided with a connecting valve rear baffle 5, which is arranged on the base 1 opposite to the discharge plate 2 and has a gap with the connecting valve 4, and the connecting valve rear baffle 5 is provided with a hollow structure 51 for passing the feed pipe 42, and the width of the hollow structure 51 in the length direction of the corresponding base 1 is not less than the maximum distance between the discharge ports 21 on both sides.

[0050] When implementing it, refer to Figure 4 , Figure 6 The connecting valve rear baffle 5 and the discharge plate 2 are arranged on both sides of the width direction of the base 1. In order to facilitate processing, the overall contours of the connecting valve rear baffle 5 and the discharge plate 2 are the same rectangle. In order to avoid friction resistance to the reciprocating motion of the feed pipe 42, the width of the hollow structure 51 (the dimension in the vertical direction) is slightly larger than the diameter of the feed pipe 42.

[0051] In actual use, combined with Figure 6 It is understood that the baffle plate 5 behind the connecting valve cooperates with the discharge plate 2 to limit the space in the front-to-back direction of the connecting valve 4 to a certain extent, which can prevent the connecting valve 4 from being offset front-to-back when reciprocating, and keep a stable gap width between the connecting valve 4 and the discharge plate 2, thereby avoiding leakage caused by the gap being too wide. In addition, the space enclosed by the baffle plate 5 behind the connecting valve, the base 1, and the discharge plate 2 can protect the connecting valve 4.

[0052] like Figure 4 , Figure 7As shown, this embodiment is further provided with a connecting valve upper baffle 6, which is connected to the upper part of the discharge plate 2 and has a gap with the connecting valve 4. In specific implementation, the gap between the connecting valve 4 and the connecting valve upper baffle 6 and the base 1 only needs to ensure that no friction is generated during the reciprocating motion of the connecting valve 4. For example, the gap width can be set to 0.3-0.8 mm, which is sufficient to avoid friction resistance and save space.

[0053] In actual use, refer to Figure 7 The baffle plate 6 on the connecting valve cooperates with the base 1 and the discharge plate 2 to limit the space in the vertical direction of the connecting valve 4 to a certain extent, which can prevent the connecting valve 4 from being excessively offset in the vertical direction during the reciprocating motion, and help avoid the phenomenon of inaccurate docking between the connecting valve 4 and the discharge port 21. In a preferred embodiment, in order to make the structure stable, such as Figure 4 As shown, the discharge plate 2, the connecting valve upper baffle 6, the connecting valve rear baffle 5 and the base 1 are connected in sequence to enclose a hollow rectangular space. It is easy to understand that at this time, there are gaps between the upper and lower parts and the front and back of the connecting valve 4 and the inner surface of the rectangular space. In particular, the gaps between the front of the connecting valve 4 and the discharge plate 2 and between the rear of the connecting valve 4 and the connecting valve rear baffle 5 are preferably set to ≤0.04mm, thereby limiting the offset amplitude of the connecting valve 4 in the front and rear directions to within 0.08mm, which can effectively prevent bait with a certain particle size from leaking from between the connecting valve 4 and the discharge plate 2, and also help to improve the alignment between the connecting valve 4 and the discharge port 21.

[0054] In addition, if Figure 4-6 As shown, in order to make the reciprocating drive amplitude of the cylinder just enough to make the feed channel 41 of the connecting valve 4 accurately dock with different discharge ports 21, this embodiment is also provided with a plurality of position sensors 7 electrically connected to the cylinder, and the position sensors 7 correspond to the positions of the discharge ports 21 one by one. Figure 4-6 The position sensor 7 can be arranged on the connecting valve rear baffle 5. For example, when two discharge ports 21 are provided, the width of the hollow structure 51 on the connecting valve rear baffle 5 can be made equal to the maximum spacing between the two discharge ports 21. At this time, the two position sensors 7 can be respectively arranged on both sides of the width of the hollow structure 51, so as to accurately monitor the position information of the push rod component 31 corresponding to the two discharge ports 21 during the reciprocating motion; when 3 or more discharge ports 21 are provided, a corresponding number of position sensors 7 can be respectively arranged on the connecting valve rear baffle 5 on the upper side of the hollow structure 51 corresponding to different discharge ports 21.

[0055] Example 3

[0056] like Figure 8-9As shown, this embodiment is further provided with a covering component based on the technical solution of embodiment 2, and the covering component is used to cover the part of the hollow structure 51 that is not blocked by the connecting valve 4. In specific implementation, as shown in the figure, the covering component is a pair of covering baffles 8, and the covering baffles 8 are respectively connected to the two sides of the connecting valve 4 corresponding to the length direction of the base 1.

[0057] When working, refer to Fig. 9 The covering baffle 8 can reciprocate with the connecting valve 4 to automatically cover the hollow structure 51. In addition, the covering baffle 8 has a simple structure, which also helps to make the overall structure of the bait dispenser lighter and reduce the difficulty of maintenance.

[0058] In a preferred embodiment, the covering area of ​​any covering baffle 8 and the connecting valve 4 is not less than the area of ​​the hollow structure 51. Fig. 9 It is understood that in actual use, the connecting valve 4 occupies the space in the hollow structure 51, and combined with the covering area of ​​the covering baffle 8, the hollow structure 51 can be completely covered, which plays a protective role for the connecting valve 4 and the internal space between the connecting valve 4 and the discharge plate 2. In addition, in order to avoid friction resistance between the covering baffle 8 and the connecting valve rear baffle 5 during reciprocating motion, the covering baffle 8 is set with a gap between the inner surface of the connecting valve rear baffle 5. Preferably, the gap width between the covering baffle 8 and the connecting valve rear baffle 5 is 0.3-0.7mm, for example, 0.5mm. This size is sufficient to ensure the reliability and smoothness of the reciprocating motion of the connecting valve 4, and can also prevent external interference from entering through the hollow structure 51, which can protect the connecting valve 4 and the push rod component 31.

[0059] like Figure 8-9 As shown, in order to facilitate the installation and fixation of the bait dispenser on other objects, the bait dispenser is also provided with a connecting component 9. In specific implementation, the connecting component 9 may include a fixing plate and a connecting piece. The fixing plate is fixedly connected to the base 1, and the connecting piece is used to connect the fixing plate and an external fixed object.

[0060] Example 4

[0061] like Fig.10As shown, on the basis of the technical solution of Example 3, this embodiment is further provided with a protective cover 10 component, which is used to cover the reciprocating drive mechanism and the connecting valve 4. In specific implementation, in order to improve the protection effect, the protective cover 10 component includes a protective cover 10 and a protective frame 11. In a preferred embodiment, the protective cover 10 covers the base 1 and completely covers the discharge plate 2, the connecting valve upper baffle 6, the connecting valve rear baffle 5, the base 1 and the cylinder from the top and both sides of the reciprocating motion, so that the bait dispenser only exposes the discharge pipe 22 and the feed pipe 42; the protective frame 11 is arranged around the hollow structure 51, and when a position sensor 7 is provided, it is arranged around the periphery of the position sensor 7. Specifically, the protective frame 11 is connected to the connecting valve rear baffle 5 and presents a protruding structure relative to the surface of the connecting valve rear baffle 5, thereby preventing external interference from damaging the position sensor 7 or invading the interior of the hollow structure at least from the top and the left and right sides.

[0062] Obviously, the above embodiments of the utility model are only examples for clearly explaining the technical solution of the utility model, and are not intended to limit the specific implementation methods of the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the claims of the utility model shall be included in the protection scope of the claims of the utility model.
