Abstract
Description
Technical Field
[0001] This utility model relates to the field of animal husbandry technology, and in particular to a knocking-type anti-feed arching mechanism. Background Technology
[0002] In modern livestock and poultry farming, feed towers and feed bins are the mainstream feed storage equipment. However, powdered feed is prone to "bridging" and "hanging on the walls" in containers due to its strong particle adhesion and poor flowability. This prevents the feed from falling naturally, affecting the feed supply of the conveyor line below, and may also cause feed spoilage and waste.
[0003] To address the aforementioned issues, existing technologies employ a cam structure to drive impacts and achieve container vibration. A motor drives the cam to rotate, which in turn pushes a striker to impact the container. The striker then resets via a reset structure, resulting in periodic impacts. In this approach, the striker and cam are directly mechanically connected, causing the impact force to be transmitted to the cam and the motor output shaft. This leads to cam wear, deformation, and even breakage, accelerated fatigue of motor components, increased connection gaps over long-term use, and unstable impact frequency and force, affecting vibration effectiveness and increasing equipment maintenance costs and downtime risks. Utility Model Content
[0004] The purpose of this invention is to provide a knock-type anti-feed arching mechanism to solve the problems of easy damage to components and unstable impact effect caused by the transmission of impact force in the prior art.
[0005] To achieve the above objectives, this utility model provides a striking-type anti-feed arching mechanism, including an outer sleeve, an impact member slidably disposed within the outer sleeve, an elastic reset member clamped between the outer sleeve and the impact member, and a traction release assembly. One end of the outer sleeve along its length is a connecting end, and the other end is an actuating end, with the actuating end fixed to the side of the storage container. The elastic reset member is elastically supported between the connecting end of the outer sleeve and the impact member to provide an elastic force that causes the impact member to pop out from the actuating end of the outer sleeve and strike the side wall of the storage container. The impact member is provided with a hook structure. The traction release assembly includes a traction device that can extend into the outer sleeve from the connecting end and a traction fork disposed on the traction device. The traction fork can be engaged with the hook structure to pull the impact member and overcome the elastic force of the elastic reset member. The traction fork can also be disengaged from the hook structure to release the impact member, which pops out and strikes the side wall of the storage container under the elastic force of the elastic reset member.
[0006] With the above structure, the impact component strikes the side wall of the storage container through the cooperation of the traction release assembly, impact component, and elastic reset component. This structure avoids the direct transmission of impact force to drive components (such as motors and cams) as in existing technologies, effectively reducing component wear and deformation, improving equipment stability and service life, and lowering maintenance costs and downtime risks.
[0007] Preferably, a base is installed at the connecting end of the outer sleeve, and the base has a through hole connecting the inside and outside of the outer sleeve, through which the traction device can extend into the outer sleeve. By setting the base and the through hole, the movement of the traction device is made more stable, ensuring the reliability of the engagement and release of the traction fork with the hook structure.
[0008] Preferably, the hook structure is a hook groove set on the impact member, and the opening of the hook groove is provided with a stepped hole; the diameter of the stepped hole is smaller than the inner diameter of the hook groove wall; the traction fork includes a base detachably fixed to the traction device and several elastic cantilever arms fixed to the base and extending towards the action end; the free end of the elastic cantilever arm is provided with an outwardly protruding top conical head; the diameter of the cross-sectional circle formed by the top conical head gradually decreases from the fixed end of the elastic cantilever arm to its free end; its minimum diameter is smaller than the diameter of the stepped hole, and its maximum diameter is larger than the diameter of the stepped hole; the middle part of the elastic cantilever arm is provided with an outwardly protruding middle conical head; the diameter of the cross-sectional circle formed by the middle conical head gradually increases from the fixed end of the elastic cantilever arm to its free end; its minimum diameter is smaller than the diameter of the through hole. The coordinated design of the hook groove, stepped hole, and the elastic cantilever arms, top conical head, and middle conical head of the traction fork achieves precise control of engagement and release, with an ingenious structure and stable operation.
[0009] Preferably, the elastic reset element is a compression spring. This design is simple, provides stable elastic force, and is easy to install and maintain.
[0010] Preferably, a baffle is provided between the elastic reset member and the impact member, and a clearance hole is provided in the middle of the baffle. The baffle can limit and protect the elastic reset member, while increasing the contact area between the elastic reset member and the impact member, thus ensuring the stress stability of the impact member.
[0011] Preferably, the impactor is a T-shaped structure; it includes a hammer head with a diameter matching the inner diameter of the outer sleeve and a hammer seat with a diameter matching the diameter of the clearance hole and capable of being inserted into the clearance hole; the hammer seat is provided with a hook structure. The T-shaped impactor increases the contact area with the baffle, and the matching of the hammer seat with the clearance hole makes the movement of the impactor more stable and the striking effect better.
[0012] Preferably, the contact point between the through hole and the central conical head is an inclined surface. This inclined surface ensures smoother contact between the central conical head and the through hole, facilitating the retraction and release of the traction fork.
[0013] Preferably, two elastic cantilever arms are provided, with a return spring sandwiched between the two top conical heads. Under the action of the return spring, the two elastic cantilever arms expand. The return spring allows the elastic cantilever arms to expand quickly after release, facilitating the next attachment operation.
[0014] Preferably, the inner wall of the outer sleeve is evenly provided with a plurality of venting grooves connecting the connecting end and the actuating end. The venting grooves can balance the air pressure inside and outside the outer sleeve, making the movement of the impact component smoother.
[0015] After adopting the above technical solution, the beneficial effects of this utility model are: This invention, a strike-type anti-feed arching mechanism, solves the problems of easy component damage and unstable impact effect caused by the transmission of impact force in existing technologies. This invention achieves the striking of the storage container's sidewall by cooperating a traction release component with an impactor and an elastic reset component. This structure avoids the direct transmission of impact force to drive components (such as motors and cams) as in existing technologies, effectively reducing component wear and deformation, improving equipment stability and service life, and lowering maintenance costs and downtime risks.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] The orientations mentioned in this specification are based on the orientation of the percussion-type anti-feed arching mechanism of this utility model during normal operation, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.
[0020] like Figure 1 and Figure 2As shown, a knocking-type anti-feed arching mechanism includes an outer sleeve 1, an impact member 2 slidably disposed within the outer sleeve 1, an elastic reset member 3 clamped between the outer sleeve 1 and the impact member 2, and a traction release assembly 4. Through the cooperation of the traction release assembly 4 with the impact member 2 and the elastic reset member 3, the impact member 2 knocks against the side wall of the storage container, thereby effectively preventing feed arching.
[0021] like Figure 5 As shown, one end of the outer sleeve 1 along its length is the connecting end 11, and the other end is the actuating end 12. A base 13 is mounted on the connecting end 11, and the base 13 has a through hole 131 connecting the inside and outside of the outer sleeve 1. The traction device 41 can extend into the outer sleeve 1 through the through hole 131. By setting the base 13 and the through hole 131, the movement of the traction device 41 is made more stable, ensuring the reliability of the engagement and release of the traction fork 42 with the hook structure. The actuating end 12 is fixed to the side of the storage container (such as a material tower or hopper); the actuating end 12 is provided with a flange 121, and the actuating end 12 of the outer sleeve 1 is detachably fixed to the side of the storage container by flange bolts. Several ventilation grooves 14 connecting the connecting end 11 and the actuating end 12 are evenly arranged on the inner wall of the outer sleeve 1. In this embodiment, four ventilation grooves 14 are provided, but in practical applications, two or three can also be provided. The ventilation groove 14 can balance the air pressure inside and outside the outer sleeve 1, making the movement of the impact member 2 smoother.
[0022] The elastic reset element 3 is elastically supported between the connecting end 11 of the outer sleeve 1 and the impact element 2, providing an elastic force that causes the impact element 2 to eject from the working end 12 of the outer sleeve 1 and strike the side wall of the storage container. In this embodiment, the elastic reset element 3 is a compression spring, which has a simple structure, stable elastic force, and is easy to install and maintain. In practical applications, it can also be a spring sheet or other elastic components.
[0023] Furthermore, a baffle 5 is provided between the elastic reset member 3 and the impact member 2, and a clearance hole 51 is provided in the middle of the baffle 5. The baffle 5 can limit and protect the elastic reset member 3 to a certain extent, while increasing the contact area between the elastic reset member 3 and the impact member 2, thus ensuring the stress stability of the impact member 2.
[0024] The impact component 2 has a T-shaped structure; it includes a hammer head with a diameter matching the inner diameter of the outer sleeve 1 and a hammer seat with a diameter matching the diameter of the clearance hole 51 and which can be inserted into the clearance hole 51; a hook structure is provided on the hammer seat. The T-shaped structure of the impact component 2 increases the contact area with the baffle 5, and the matching of the hammer seat with the clearance hole 51 makes the movement of the impact component 2 more stable and the striking effect better.
[0025] One end of the elastic reset member 3 abuts against the connecting end 11 of the outer sleeve 1, and the other end abuts against the baffle 5.
[0026] The hook structure is a hook groove 21 set on the impact member 2, and a stepped hole 22 is provided at the opening of the hook groove 21; the diameter of the stepped hole 22 is smaller than the inner diameter of the groove wall of the hook groove 21.
[0027] The traction release assembly 4 includes a traction device 41 that can extend into the outer sleeve 1 from the connecting end 11, and a traction fork 42 mounted on the traction device 41. The traction fork 42 can engage with a hook structure to pull the impact member 2 against the elastic force of the elastic reset member 3. The traction fork 42 can also disengage from the hook structure to release the impact member 2. Under the elastic force of the elastic reset member 3, the impact member 2 pops out and strikes the side wall of the storage container. The traction fork 42 of the traction release assembly 4 engages with the hook structure of the impact member 2 to pull the impact member 2 against the elastic force of the elastic reset member 3. When the traction fork 42 disengages from the hook structure, the impact member 2 pops out and strikes the side wall of the storage container under the elastic force of the elastic reset member 3. This structure avoids the direct transmission of impact force to drive components (such as motors and cams) as in the prior art, effectively reducing wear and deformation of components, improving the stability and service life of the equipment, and reducing maintenance costs and downtime risks.
[0028] The traction device 41 can be an electric cylinder, a pneumatic cylinder, or an electric push rod. When the traction device 41 is an electric push rod, its cylinder body is fixed to the outer wall of the storage container or a related support structure via a mounting bracket. This electric push rod is electrically connected to the central controller of the aquaculture system. The controller can control the extension and retraction of the electric push rod according to a preset time interval or a received material level blockage signal. Its output shaft is fixed to the traction fork 42 and can be detachably fixed by plugging or screwing.
[0029] like Figure 6 As shown, the traction fork 42 includes a base 421 detachably fixed to the traction device 41 and several elastic cantilever arms 422 fixed to the base 421 and extending towards the action end 12. The free end of each elastic cantilever arm 422 has an outwardly protruding top conical head 423. The diameter of the cross-sectional circle formed by the top conical head 423 gradually decreases from the fixed end of the elastic cantilever arm 422 to its free end; its minimum diameter is smaller than the diameter of the stepped hole 22, and its maximum diameter is larger than the diameter of the stepped hole 22. The middle part of each elastic cantilever arm 422 has an outwardly protruding middle conical head 424; the diameter of the cross-sectional circle formed by the middle conical head 424 gradually increases from the fixed end of the elastic cantilever arm 422 to its free end; its minimum diameter is smaller than the diameter of the through hole 131. The coordinated design of the hook groove 21, the stepped hole 22, the elastic cantilever 422 of the traction fork 42, the top conical head 423, and the middle conical head 424 enables precise control of hooking and releasing, resulting in an ingenious structure and stable operation.
[0030] Two elastic cantilever arms 422 are provided, with a return spring 425 sandwiched between the two top conical heads 423. The two top conical heads 423 are provided with corresponding receiving grooves for the return spring 425 to limit its movement and prevent it from dislodging. The return spring 425 allows the elastic cantilever arm 422 to quickly expand after release, facilitating the next attachment operation.
[0031] The contact point between the through hole 131 and the central conical head 424 is an inclined surface. This inclined surface ensures smoother contact between the central conical head 424 and the through hole 131, facilitating the retraction and release of the traction fork 42.
[0032] like Figures 2-4 As shown in the figure, the working process of a tapping-type anti-bridging feed mechanism is as follows: like Figure 2 As shown, the traction process: The traction device 41 drives the traction fork 42 to extend into the outer sleeve 1. The top conical head 423 of the traction fork 42 expands under the action of the return spring 425. When the top conical head 423 contacts the stepped hole 22 of the hook groove 21, due to the conical structure of the top conical head 423, the elastic cantilever 422 contracts, causing the top conical head 423 to enter the hook groove 21. Then, the elastic cantilever 422 expands under the action of the return spring 425, and the top conical head 423 is engaged in the hook groove 21, realizing the connection between the traction fork 42 and the impact member 2.
[0033] like Figure 3 As shown, the drop-down process: The traction device 41 drives the traction fork 42 to move towards the connecting end 11, and the traction impact member 2 overcomes the elastic force of the elastic reset member 3, causing the elastic reset member 3 to be compressed.
[0034] like Figure 4 As shown, the release process: When the traction fork 42 moves to the point where the middle conical head 424 contacts the through hole 131 of the base 13, the elastic cantilever 422 retracts due to the conical structure of the middle conical head 424 and the inclined surface design of the through hole 131, and the top conical head 423 disengages from the hook groove 21, thereby releasing the traction fork 42 from the impact member 2.
[0035] Finally, under the elastic force of the elastic reset member 3, the impact member 2 pops out from the working end 12 of the outer sleeve 1 and strikes the side wall of the storage container, causing the storage container to vibrate, thereby destroying the "bridging" and "hanging" structure of the feed and preventing the feed from arching.
[0036] This invention, through the above-described structure and working process, effectively solves the problems of easy damage to components and unstable impact effects caused by impact force transmission in the prior art, improves the stability and service life of the equipment, reduces maintenance costs and downtime risks, and can be widely used in feed storage equipment for livestock and poultry farming.
[0037] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
