Description

Technical Field

[0001] The utility model belongs to the technical field of pig farm feed lines, in particular to a chain plug disc of a pig farm feed line. Background Art

[0002] The feed line is an automatic feeding equipment that is widely used in pig farms. By using a plug tray feed line to make a loop in the pig house, it can achieve timed and quantitative feeding in conjunction with feeding equipment. It is mostly used for pigs in different growth stages such as sow houses, fattening houses, and nurseries.

[0003] The chain stopper of the existing stopper material line is mainly composed of a chain and a scraper sleeved on the outside of the chain. The chain is composed of chain links connected to each other in a perpendicular manner. When the chain stopper is used for loading, the chain links vertically connected to each other occupy a large space, the storage space between adjacent scrapers is small, and the amount of material used to manufacture the chain links is also large. Therefore, further improvement can be made. Utility Model Content

[0004] In order to solve the problems mentioned in the background technology, the utility model provides the following technical solutions: a chain plug plate for a pig farm feed line, comprising a chain rod and a scraper, the scraper is sleeved on the middle part of the chain rod, and a connecting component is movably connected between two adjacent groups of chain rods. The connecting component is in the shape of a long rod, and its outer diameter does not exceed 10 mm. One end of the connecting component is rotatably connected to one side of the center link, and the other end is detachably mounted on another center link.

[0005] As an optimization, the central link is a circular chain ring, and the connecting component includes a screw rod movably inserted into the middle of the chain ring. The other end of the screw rod passes through another chain ring, and a nut is threadedly sleeved on its end. By screwing the nut sleeved on the end of the screw rod, a connection function is achieved. With this structure, the space occupied by the chain plug is smaller than that of the conventional structure, which can effectively expand the material storage space and save about a quarter of the chain manufacturing material.

[0006] As an optimization, outward-spreading limit sleeves are provided on both sides of the center of the scraper blade, and the middle part of the chain rod is concave inward in an hourglass shape. The limit sleeves are fitted on the inclined arc surface of the chain rod to firmly position the scraper blade and avoid the scraper blade from shifting during use. A ball shaft is fixedly installed at the center of one side of the chain rod, and a mounting hole is opened at the center of the other side of the chain rod.

[0007] As an optimization, the connecting component includes a connecting tube, a sliding rod is slidably inserted inside the connecting tube, a ball shell is fixedly installed on one end of the sliding rod located outside the connecting tube, a movable groove is provided on the end of the connecting tube away from the ball shell, and the sliding rod is located at one end inside the connecting tube and an openable and closable limit assembly is provided in the movable groove.

[0008] As an optimization, the ball shell is sleeved on the outside of the ball shaft, and the openable and closable limit assembly is inserted into the mounting hole. The mounting hole as a whole and one end of the ball shaft are movably connected through the ball shell. The limit assembly is then inserted into the mounting hole of another ball shaft and opened for limiting, thereby facilitating the connection of chain rods one by one. Moreover, the multi-directional freedom after the ball shaft and the ball shell are connected can avoid getting stuck when turning the material.

[0009] As an optimization, a limiting hole is opened inside the connecting tube, a fixing ring is slidably connected inside the limiting hole, and the fixing ring is fixedly installed on the outside of the sliding rod, and a compression spring is fixedly installed between the fixing ring and the inner wall of the limiting hole.

[0010] As an optimization, the openable and closable limiting assembly includes an incomplete gear rotatably connected in a movable groove, a support plate is fixedly installed on the outer side of the incomplete gear, and a rack plate is fixedly installed on the outer wall of the slide rod located in the movable groove.

[0011] As an optimization, the rack plate is arranged corresponding to the incomplete gear, and the incomplete gear and the rack plate are meshed and connected. The support plate is pressed and deflected into the movable groove, and no longer protrudes from the surface of the connecting tube. Therefore, it can be inserted into the mounting hole. After entering the mounting hole, it opens outward and resets, and can be stuck on the bottom wall of the mounting hole to play a limiting connection role.

[0012] Beneficial effects: Compared with the conventional chain plug structure, the utility model occupies less space, can effectively expand the material storage (or material guiding) space, can save about one-fourth of the chain manufacturing material, and can be easily installed and disassembled and replaced; the utility model adopts the design of the middle part of the chain rod being inwardly concave in an hourglass shape, and the limit sleeves arranged on both sides of the scraper can prevent the scraper from being offset during use, and then connects in sequence through the overall rod-shaped connecting parts, which can significantly reduce the occupied space compared with the traditional chain; during installation, the support plate will be compressed and deflected into the movable groove, and the rack plate will be driven to move to one side of the mounting hole through the incomplete gear, so the fixing ring will be driven to compress the compression spring, and after the support plate moves to the inside of the mounting hole, it will no longer be compressed, so it will be driven to return to the open state under the action of the compression spring, and then it will play a limiting role to complete the installation, and when disassembling, the support plate will be driven to deflect into the movable groove by pushing the sliding rod, and then the connecting tube can be taken out, so that it is convenient to install and disassemble and replace.

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solution of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Please refer to Figure 1 A chain plug for a pig farm feed line includes a chain rod 1 and a scraper 2. The scraper 2 is sleeved on the middle of the chain rod 1. A connecting component 3 is movably connected between two adjacent groups of chain rods 1. The connecting component 3 is in the shape of a long rod, and its outer diameter does not exceed 8 mm. One end of the connecting component 3 is rotatably connected to one side of a central link, and the other end is detachably installed in the middle of another central link.

[0022] In this embodiment, the central link is a circular chain link 01, and the connecting component 3 includes a screw rod 02 movably inserted into the middle of the chain link 01. The other end of the screw rod 02 movably passes through another chain link 01, and a nut 03 (double nut) is threadedly sleeved on its end. During installation, by screwing the nut 03 sleeved on the end of the screw rod 02, it will play a connecting role. Compared with the conventional structure, this structure occupies less space, can expand the material storage (material guide) space, and can also save a quarter of the chain manufacturing material. When in use, the screw rod can be installed and removed by screwing the nut 03, and the chain plug plate can be installed or removed conveniently and quickly.

[0023] Embodiment 2: A chain plug for a pig farm feed line comprises a chain rod 1 and a scraper 2, wherein the scraper 2 is sleeved on the middle of the chain rod 1, and a connecting component 3 is movably connected between two adjacent groups of chain rods 1. The connecting component 3 is in the shape of a long rod, and its outer diameter does not exceed 8 mm. One end of the connecting component 3 is rotatably connected to one side of a central link, and the other end is detachably installed in the middle of another central link.

[0024] In this embodiment, please refer to Figure 3-4 , outwardly-branched limit sleeves 4 are provided on both sides of the center of the scraper 2, and the middle part of the chain rod 1 is concave inward in an hourglass shape. The limit sleeve 4 is fitted on the oblique arc surface of the chain rod 1 to firmly position the scraper 2 and prevent the scraper 2 from shifting during use. A ball shaft 5 is fixedly installed at the center of one side of the chain rod 1, and a mounting hole 6 is opened at the center of the other side of the chain rod 1.

[0025] See also Figure 4-5 The connecting component 3 includes a connecting tube 7, a sliding rod 8 is slidably inserted inside the connecting tube 7, and a ball shell 9 is fixedly installed on one end of the sliding rod 8 located outside the connecting tube 7. The ball shell 9 is sleeved on the outside of the ball shaft 5. A movable groove is provided at one end of the connecting tube 7 away from the ball shell 9. The sliding rod 8 is located at one end inside the connecting tube 7 and is provided with an openable and closable limit assembly in the active groove. The openable and closable limit assembly is inserted in the mounting hole 6, and the mounting hole 6 as a whole is movably connected to one end of the ball shaft 5 through the ball shell 9. The limit assembly is then inserted into the mounting hole 6 of another ball shaft 5 and then opened for limiting, so as to facilitate the connection of the chain rods 1 one by one, and the multi-directional freedom after the ball shaft 5 and the ball shell 9 are connected can avoid being stuck when turning the feeding as much as possible;

[0026] See also Figure 4-5 A limiting hole 10 is provided inside the connecting tube 7, a fixing ring 11 is slidably connected inside the limiting hole 10, and the fixing ring 11 is fixedly installed on the outside of the slide rod 8, and a compression spring 12 is fixedly installed between the fixing ring 11 and the inner wall of the limiting hole 10;

[0027] See also Figure 6 The openable and closable limit assembly includes an incomplete gear 13 rotatably connected in the movable groove, a support plate 14 is fixedly installed on the outer side of the incomplete gear 13, and a rack plate 15 is fixedly installed on the outer wall of the slide bar 8 located at the movable groove. The rack plate 15 is arranged corresponding to the incomplete gear 13, and the incomplete gear 13 and the rack plate 15 are meshed and connected. The support plate 14 is pressed and deflected into the movable groove, and no longer protrudes from the surface of the connecting tube 7, so it can be inserted into the mounting hole 6. After entering the mounting hole 6, it opens outward and resets, and can be stuck on the bottom wall of the mounting hole 6 to play a limiting connection role.

[0028] When repairing and replacing a chain plug at a certain link, it is only necessary to push the slide bar 8 to move toward the inside of the connecting tube 7, which will drive the incomplete gear 13 to rotate through the rack plate 15, so that the support plate 14 will rotate into the movable groove. At this time, the support plate 14 no longer protrudes from the surface of the slide bar 8, and the connecting tube 7 can be pulled outward, thereby facilitating the removal of the chain plug at the faulty section.

[0029] During installation, it is only necessary to align the connecting tube 7 with the mounting hole 6 and insert it. At this time, the support plate 14 will be squeezed and deflected into the movable groove, and at the same time, the rack plate 15 will be driven to move to one side of the mounting hole 6 through the incomplete gear 13, and then the slide bar 8 will be driven to slide synchronously along the inner wall of the connecting tube 7, so the compression spring 12 will be compressed by the fixing ring 11. After the support plate 14 is completely moved into the mounting hole 6 as a whole, it will no longer be squeezed. Then, under the action of the compressed compression spring 12, the slide bar 8 will be driven to reset, and then the support plate 14 will be driven to deflect and reset to the open state, and then it can be against the bottom wall of the mounting hole 6, thereby completing the replacement and installation of the chain plug.

[0030] In summary, the chain plug structure of the utility model occupies less space than conventional structures, can effectively expand the material storage (material guiding) space, and can also save about a quarter of the chain manufacturing materials, and is also convenient for installation and disassembly and replacement. The middle part of the chain rod 1 is designed to be concave inward in an hourglass shape, and the limit sleeves 4 are set on both sides of the scraper 2 to prevent the scraper 2 from being offset during use, and then the connection parts 3 that are in the shape of a rod as a whole are connected in sequence, which can reduce the occupied space compared to traditional chains. During installation, the support plate 14 will be compressed and deflected into the movable groove, and the rack plate 15 will be driven to move to one side of the installation hole 6 through the incomplete gear 13, so the fixing ring 11 will be driven to compress the compression spring 12. After the support plate 14 moves to the inside of the installation hole 6, it is no longer compressed, so the support plate 14 will be driven to return to the open state under the action of the compression spring 12, and then it will play a limiting role to complete the installation. During disassembly, it can be known that by pushing the slide rod 8, the support plate 14 will be driven to deflect into the movable groove, and then the connecting tube 7 can be taken out, which can facilitate installation and disassembly and replacement.
