Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of laying hen breeding, especially a closed conveying link head. BACKGROUND

[0002] In the field of laying hen breeding, the central egg collection system is a key device for connecting various henhouses and realizing directional transmission of eggs. Its efficient and stable operation is crucial for improving breeding efficiency. The traditional central egg collection system mainly relies on the circular rotation of the conveying chain under the drive of the motor to complete the directional transmission of eggs. For example, the chain ring turning central egg collection line disclosed in Chinese patent CN 216888530 U shows the application of the conveying chain in a complex path.

[0003] However, in actual application, due to the layout differences of different breeding sites, the length required by the conveying chain is often different. The traditional overall structure of the conveying chain not only has high production cost, but also has many inconveniences in the installation and maintenance process. Once a part of the chain is damaged, the whole chain often needs to be replaced, which not only increases the maintenance cost, but also affects the production efficiency. UTILITY MODEL CONTENTS

[0004] The utility model aims to provide a closed conveying link head, which can conveniently connect or disconnect the chain links of the chain, thereby realizing flexible adjustment of the length of the chain, reducing production cost, and improving the convenience of installation and maintenance.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a closed conveying link head, which comprises a chain ring body, an opening for clamping the chain links of the chain into the chain ring body and a hook located on both sides of the opening are arranged on the top of the chain ring body; the hook is used for connecting the chain links of the chain on both sides; further comprising a baffle which is detachably installed on the chain ring body and closes the opening, and the baffle is locked and connected with both sides of the opening respectively.

[0006] After adopting the above-mentioned structure, the length of the chain can be produced modularly, and then the device is flexibly assembled, thereby reducing the production cost and improving the convenience of installation and maintenance; through the setting of the opening, the clamping of the chain ring is facilitated, and through the setting of the baffle, the opening is closed, the chain ring is prevented from coming out, and the running stability of the conveying chain is realized.

[0007] Preferably, threaded holes are arranged on both sides of the opening on the chain ring body, through holes corresponding to the threaded holes are opened on the baffle, bolts are fitted and installed in the threaded holes, and the baffle is fixed on the chain ring body by the bolts. This connection method is simple and reliable, and is convenient for installation and disassembly.

[0008] Preferably, the chain link body is provided with a sunken platform on both sides of the opening, the sunken platform is a planar structure, the baffle is tightly attached to the sunken platform and does not protrude from the chain link body. By providing the sunken platform, the contact area of the baffle and the chain link body is increased, thereby ensuring the stability of the connection. The baffle does not protrude from the chain link body, thereby avoiding the problems of poor operation or damage of the chain caused by the protruding baffle.

[0009] Preferably, the through hole is a sunken hole. This structure reduces the occupation of the chain operation space and further improves the stability of the chain.

[0010] Preferably, a limiting groove is arranged on each of the sunken platforms, and a limiting protrusion corresponding to the limiting groove is arranged on the baffle and is clamped into the limiting groove. By arranging the limiting protrusion and the limiting groove, the tension of the chain on both sides is dispersed to the limiting protrusion and the limiting groove, thereby reducing the pressure of the bolt and effectively preventing the baffle from loosening or falling off during the operation of the chain.

[0011] Preferably, one limiting groove is arranged on each sunken platform and is arranged at a position away from the opening on the sunken platform. This design avoids the interference of the limiting groove on the closure of the opening.

[0012] Preferably, the limiting groove is a trapezoidal groove, and the limiting protrusion is a trapezoidal block matched with the trapezoidal groove. By arranging this structure, the freedom of the baffle in two directions is limited, and the pressure of the bolt is further reduced.

[0013] Preferably, the threaded hole is arranged on the sunken platform and is not located in the limiting groove. By this arrangement, the threaded hole has sufficient depth, thereby ensuring the overall strength of the chain link body.

[0014] Preferably, the chain link body has the same size as the chain link and is welded with a connecting rod flush with the support rod on the chain link on the side opposite to the opening. This design ensures the stability and consistency of the chain link body in the chain, thereby avoiding the problems of chain operation caused by the size or shape difference of the chain link body.

[0015] After adopting the above technical scheme, the beneficial effects of the present application are as follows:

[0016] The closed conveying link head solves the technical problems of high production cost, high maintenance and assembly difficulty of the existing conveying chain in the prior art. The chain link of the chain can be conveniently connected or disconnected, thereby realizing flexible adjustment of the length of the chain, reducing the production cost and improving the convenience of installation and maintenance.

[0022] The utility model is further described below in combination with the drawings.

[0023] The directions involved in the specification are based on the directions of the closed conveying link head in normal working, and are not limited to the directions in storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0024] Example one:

[0025] As Figure 1 and Figure 2 As shown in figures 1 and 2, a closed conveying link head comprises a chain ring body 1, and the top of the chain ring body 1 is provided with an opening 11 for the chain link 2 to be clamped in and hooks 12 on both sides of the opening 11. The hooks 12 are used to be connected with the chain links 2 on both sides to ensure the continuity and stability of the chain. In addition, the closed conveying link head further comprises a stop sheet 3 which is detachably installed on the chain ring body 1 and closes the opening 11, and the two sides of the stop sheet 3 are respectively locked and connected with the two sides of the opening 11 to prevent the chain link 2 from accidentally falling off.

[0026] The two sides of the stop sheet 3 can be fixed on the two sides of the opening 11 by welding or riveting. In this embodiment, in order to facilitate disassembly, the chain ring body 1 is provided with threaded holes on both sides of the opening 11, and the stop sheet 3 is provided with through holes corresponding to the threaded holes. The stop sheet 3 is fixed on the chain ring body 1 by cooperating with the threaded holes through bolts, so as to close the opening 11. This connection method is simple and reliable, and is convenient for installation and disassembly.

[0027] In order to optimize the structural strength and flatness, the chain ring body 1 is provided with a sunken platform 13 on both sides of the opening 11. The sunken platform 13 is a planar structure, and the stop sheet 3 is tightly attached to the sunken platform 13, thereby increasing the contact area of the stop sheet 3 and the chain ring body 1 and ensuring the stability of the connection. The stop sheet 3 does not protrude from the chain ring body 1, avoiding the problem of poor chain operation or damage caused by the protrusion of the stop sheet 3.

[0028] The through hole is preferably a sink hole to reduce the occupancy of the chain running space and further improve the stability of the chain.

[0029] In addition, the size of the chain link body 1 is the same as that of the chain link 2, and a connecting rod 14 flush with the support rod 21 on the chain link 2 is welded on the side opposite to the opening 11 of the bottom. This design ensures the stability and consistency of the chain link body 1 in the chain, avoiding chain running problems caused by size or shape differences of the chain link body 1.

[0030] Through the arrangement of the structure, the chain can adopt a modular length, reducing the production cost and installation and maintenance difficulty. The structure is simple and compact, does not occupy additional space, and ensures the smooth running of the chain.

[0031] Example two:

[0032] As shown in Figure 3 In order to enhance the connection stability of the baffle 3 and the chain link body 1, a limiting groove 131 is arranged on each side of the sink surface 13, and a limiting protrusion 31 corresponding to the limiting groove 131 is arranged on the baffle 3. The limiting protrusion 31 is clamped into the limiting groove 131, and through the arrangement of the limiting protrusion 31 and the limiting groove 131, the connection stability is enhanced, the chain tension is effectively dispersed, the stress on the bolt is reduced, the service life is prolonged, and the baffle 3 is effectively prevented from loosening or falling off during the running of the chain. One limiting groove 131 is arranged on each sink surface 13, and the limiting groove 131 is arranged on the sink surface 13 away from the opening 11, so as to avoid interference caused by the closure of the opening 11.

[0033] The threaded hole is arranged on the sink surface 13 and is not located in the limiting groove 131, so as to ensure that the threaded hole has sufficient depth and the overall strength of the chain link body 1 is guaranteed.

[0034] Example three:

[0035] As shown in Figure 4 This embodiment is further improved on the basis of example two, the limiting groove 131 is preferably a trapezoidal groove, and the limiting protrusion 31 is a trapezoidal block matched therewith. This structure is convenient to install and disassemble, and provides good locking effect. During installation, the trapezoidal block is slid into the trapezoidal groove from one side, and after installation, the bolt is fixed and locked. Through the arrangement of this structure, the freedom of the baffle 3 in two directions is limited, and the pressure on the bolt is reduced again.

[0036] Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. Changes, modifications, additions or replacements made by the skilled in the art within the essential scope of the utility model should also be within the protection scope of the utility model.
