Description

Technical Field

[0001] The invention relates to the field of material transportation, and in particular to a livestock breeding batching equipment. Background Art

[0002] In production, conveying devices are often used to transfer or transport materials. The tube chain conveyor is the latest type of conveying equipment in the field of conveying. In recent years, with the improvement of environmental awareness in various industries, the tube chain conveyor has been widely used in feed, chemical, fertilizer, metallurgy, pharmaceutical, plastic and other industries due to its dust-free conveying performance advantage. The tube chain conveyor has high conveying efficiency and can continuously convey various bulk materials such as powders, granules, and small blocks. Its unique ring tube sealing structure provides both dust-free conveying of powders and environmental protection, and also reduces direct contact between toxic and harmful substances and the human body; in addition, the tube chain conveyor can be used in a more complex space environment, and has a beautiful shape. The conveying distance of a single machine can reach 60m, and the lifting height can reach 40m. Therefore, due to its unique advantages, the tube chain conveyor is becoming more and more popular in the batching and transportation of livestock feed.

[0003] The main disadvantages of the current pipe chain conveyor are: first, the running resistance between the disc and the pipeline is large, which leads to the large load-bearing capacity of the chain and is easy to wear and break, affecting the feeding efficiency; second, due to the use of a sealed pipeline structure for transportation, and the gap between the disc diameter and the pipeline becomes larger and larger with wear, after each feeding is completed, there is always material retained in the pipeline, affecting the feeding effect, and after a long period of shutdown, the material retained in the pipeline is prone to mold and deterioration, affecting subsequent use.

[0004] To solve the above problems, the Chinese patent document with application number 202010064904.6 and authorization announcement number CN 111169947 B discloses a self-cleaning, low-noise tube chain feed conveyor, which is equipped with a tube wheel on the disc body used for feeding to reduce friction, and at the same time, a brush is set to clean the residual material inside the pipe. Although this solution can alleviate the running resistance and material residue, the brush is always in contact with the inner wall of the pipe, which will cause the brush to wear seriously. At the same time, the gap between the disc body and the pipe is compensated by the brush, and the brush and the inner wall of the pipe are always in a friction state, resulting in large friction resistance and reduced conveying efficiency. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 7As shown, a livestock breeding batching equipment of the present invention can efficiently transport and distribute feed to designated feeding positions, which includes a feed pipeline 110, a conveying component and a driving device 100. The feed pipeline 110 is hollow inside and has a circular cross-section. The conveying component is arranged inside the feed pipeline 110, and the driving device 100 is connected in series in the feed pipeline 110. The driving device 100 is used to drive the conveying component to operate in the feed pipeline 110. A feed port 130 and a discharge port 140 are provided on the feed pipeline 110. The material is put into the feed port 130, and a material flow is formed under the drive of the conveying component, and finally discharged from the discharge port 140. Figure 1 The arrow in the middle shows the direction of movement of the conveying component.

[0035] The conveying assembly includes a conveying chain 120 and a conveying plate 200. The conveying chain 120 includes first links and second links that are alternately arranged and connected end to end. The first links and the second links have the same structure and are runway-shaped. Relative to the axis of the conveying pipeline 110, the first links are horizontally arranged and the second links are vertically arranged.

[0036] The conveyor plate 200 includes a main plate body 230, a scraper 240 and a transmission control mechanism. The main plate body 230 is fixedly connected to the second chain link. There is a gap between the outer peripheral wall of the main plate body 230 and the inner peripheral wall of the material conveying pipeline 110. The main plate body 230 is provided with rotatable rollers 231. The rollers 231 are evenly distributed along the circumferential direction of the main plate body 230. The axes of the rollers 231 are perpendicular to the radial lines of the main plate body 230. The outer peripheral walls of the rollers 231 are in contact with the inner peripheral wall of the material conveying pipeline 110. The rollers 231 are used to rotate the conveyor plate 200. Positioning and reducing the friction resistance between the conveying disc 200 and the inner wall of the conveying pipeline 110 during operation; the scraper 240 is radially slidably arranged on the side of the main disc body 230 away from the forward direction, there are multiple scrapers 240 and they are evenly distributed along the circumferential direction, and a connecting spring 241 is arranged between the scraper 240 and the main disc body 230. The initial connecting spring 241 prompts the scraper 240 to move inward (close to the center of the circle is inward, away from the center of the circle is outward), and the outer wall of the scraper 240 can fit with the inner wall of the conveying pipeline 110.

[0037] The transmission control mechanism is disposed on the main plate 230 and participates in pushing the material. The transmission control mechanism is used to control the scrapers 240 to extend in groups of two from bottom to top, and the number of extended scrapers 240 matches the amount of material in the conveying pipeline 110 .

[0038] It should be noted that the gap reserved between the main plate body 230 and the inner wall of the material conveying pipeline 110 is relatively small. Setting this gap can ensure normal material conveying and reduce the friction resistance between the conveying plate 200 and the material conveying pipeline 110 at the same time. During the feeding process, the transmission control mechanism controls the extension of the scraper 240 according to the amount of material. When there is less material in the feeding pipe 110, the material will be located at the bottom of the feeding pipe 110 due to gravity, so the scraper 240 at the bottom extends to participate in pushing the material. At the same time, the scraper 240 can fit the inner wall of the feeding pipe 110 after being extended, so the scraper 240 can push almost all the material, thereby reducing the material residue inside the feeding pipe 110. The more material accumulated inside the feeding pipe 110, the more the scraper 240 extends. By matching the number of extended scrapers 240 with the amount of material, the number of scrapers 240 that do not participate in feeding can be reduced, and while avoiding material residue, the friction between the scraper 240 and the inner wall of the feeding pipe 110 is reduced (the more scrapers 240 are extended, the greater the friction between the conveying plate 200 and the feeding pipe 110), thereby improving the feeding efficiency and extending the service life of the equipment.

[0039] In a further embodiment, Figure 3 , Figure 5 and Figure 6 As shown, the transmission control mechanism includes an upper push plate 220, a lower push plate 210, a first expansion ring 260 and a second expansion ring 261. The main disk body 230 is hollow inside and one side close to the forward direction is open. The upper push plate 220 and the lower push plate 210 are slidably arranged at the open end of the main disk body 230 along the axial direction of the main disk body 230. The upper push plate 220 and the lower push plate 210 are symmetrically arranged up and down and are slidingly sealed with the main disk body 230. The upper push plate 220 and the lower push plate 210 are both connected to the main disk body 230 with a first spring 211. Initially, the first spring 211 urges the upper push plate 220 and the lower push plate 210 to move in a direction away from the main disk body 230.

[0040] The first expansion ring 260 and the second expansion ring 261 are both rotatably disposed on the side of the main disk body 230 away from the forward direction and are coaxial with the main disk body 230. The first expansion ring 260 and the second expansion ring 261 have the same structure and their outer peripheral walls have cam-shaped curved surfaces. The first expansion ring 260 is located on the rear side of the second expansion ring 261 (the front is close to the forward direction and the rear is away from the forward direction) and the two are disposed face to face.

[0041] The main disk body 230 is provided with a push rod 250 which can slide along its radial direction. There are multiple push rods 250 and they correspond one by one to the scraper 240. The push rod 250 that controls the right half of the scraper 240 corresponds to the first expansion ring 260, and the push rod 250 that controls the left half of the scraper 240 corresponds to the second expansion ring 261. Initially, the two lowest push rods 250 are located in the high and low point transition zone of the cam-shaped surface of the corresponding first expansion ring 260 or the second expansion ring 261.

[0042] The upper push plate 220 and the lower push plate 210 are connected to the first expansion ring 260 and the second expansion ring 261 through a transmission unit. The transmission unit is used to convert the movement of the upper push plate 220 and the lower push plate 210 into the rotation of the first expansion ring 260 and the second expansion ring 261, and make the first expansion ring 260 and the second expansion ring 261 rotate synchronously in the opposite direction for half a circle, that is, the first expansion ring 260 and the second expansion ring 261 rotate synchronously in the opposite direction for 180 degrees.

[0043] Further, the transmission unit includes an end gear 271, a driving gear 270, a first rack 212 and a second rack 222;

[0044] The end faces of the first expansion ring 260 and the second expansion ring 261 that are close to each other are both provided with end face teeth 262 , the end face gear 271 is sandwiched between the first expansion ring 260 and the second expansion ring 261 and meshes with the end face teeth 262 , and the driving gear 270 is fixedly connected to one side of the end face gear 271 .

[0045] The first rack 212 is arranged on the lower push plate 210, and the second rack 222 is arranged on the upper push plate 220. The first rack 212 and the second rack 222 are located on the same side and can both be engaged with the driving gear 270. Initially, the first rack 212 is engaged with the driving gear 270 and the second rack 222 is disengaged from the driving gear 270. When the first rack 212 and the second rack 222 move to the extreme position, they can both push the first expansion ring 260 and the second expansion ring 261 to rotate 90 degrees.

[0046] Furthermore, in order to ensure balanced force and smooth and reliable transmission, end gears 271 are clamped on both sides of the first expansion ring 260 and the second expansion ring 261. Two corresponding drive gears 270 are provided, and the two drive gears 270 are connected for relative rotation via a connecting rod.

[0047] The left and right sides of the lower push plate 210 are both provided with first racks 212, and the two first racks 212 are arranged opposite to each other up and down; the left and right sides of the upper push plate 220 are both provided with second racks 222, and the two second racks 222 are arranged opposite to each other up and down; the first rack 212 and the second rack 222 located on the same side cooperate with a corresponding driving gear 270.

[0048] The material is put into the material conveying pipeline 110 , and the driving device 100 drives the conveying assembly to operate and then drives the conveying plate 200 to move along the material conveying pipeline 110 . The conveying plate 200 pushes the material to move and discharge it at the discharge port 140 .

[0049] In the process of conveying materials, due to the gravity of the materials, the materials are located at the bottom of the conveying pipe 110. Under the resistance of the materials, the lower push plate 210 moves relative to the main plate 230 (moves backward relative to the main plate 230). During the movement of the lower push plate 210, the first rack 212 drives the driving gear 270 to rotate. The rotation of the driving gear 270 drives the end gear 271 to rotate, thereby driving the first expansion ring 260 and the second expansion ring 261 to rotate in the opposite direction (refer to Figure 4 , the first expansion ring 260 rotates counterclockwise, and the second expansion ring 261 rotates clockwise), the first expansion ring 260 and the second expansion ring 261 rotate to squeeze the push rod 250 on the same plane respectively, and the push rod 250 pushes the scraper 240 outward. After the scraper 240 moves outward, it contacts the inner circumference of the material conveying pipeline 110, and can push all the materials to avoid material residue. The first expansion ring 260 controls the scraper 240 on the right half, and the second expansion ring 261 controls the scraper 240 on the left half. The first expansion ring 260 and the second expansion ring 261 will push the push rod 250 from bottom to top in sequence, so that the scraper 240 expands from bottom to top in sequence. At the same time, the movement of the first rack 212 can only drive the first expansion ring 260 and the second expansion ring 261 to rotate 90 degrees through the driving gear 270 and the end gear 271, while the movement of the second rack 222 will drive the first expansion ring 260 and the second expansion ring 261 to continue to rotate 90 degrees in the same direction through the driving gear 270 and the end gear 271.

[0050] At the same time, due to the gravity of the material, the lower push plate 210 at the bottom will move first. As the material increases, the lower push plate 210 moves to the limit, and the material gradually contacts the upper push plate 220. After the upper push plate 220 moves, the second rack 222 engages with the driving gear 270 to continue to push the first expansion ring 260 and the second expansion ring 261 to rotate. Through two superimposed movements, the first expansion ring 260 and the second expansion ring 261 can rotate 180 degrees, thereby squeezing all the push rods 250 and expanding all the scrapers 240 to contact the pipe wall.

[0051] In summary, when there is not much material in the material delivery pipeline 110, and due to gravity, the material will be located at the bottom of the material delivery pipeline 110, and when the material is pushed, it will first generate resistance to the lower push plate 210, thereby pushing the lower push plate 210 to move. Since there is not much material, the lower push plate 210 will not move to the limit position. At this time, the lower push plate 210 drives the driving gear 270 to rotate through the first rack 212 and then drives the end gear 271 to rotate, so that the first expansion ring 260 and the second expansion ring 261 rotate a certain angle, and the two scrapers 240 located at the bottom extend and contact the pipe wall to achieve a sliding sealing effect, so as to prevent residual material in the material delivery pipeline 110. When the material gradually increases, the movement of the lower push plate 210 increases, and after the lower push plate 210 moves to the limit, the upper push plate 220 moves, and the remaining scrapers 240 can be opened in sequence to achieve sliding sealing. Through the above, when there is little material, not all scrapers 240 will be opened, and the extension amount of the scrapers 240 matches the amount of material, which reduces material residue while reducing the friction between the conveying plate 200 and the conveying pipeline 110, reducing wear and extending the service life.

[0052] In a further embodiment, Figure 3 and Figure 6 As shown, a horizontally extending partition is provided inside the main disk body 230, and a first one-way limit block 280 and a second one-way limit block 281 which can slide up and down are inserted in the partition. The first one-way limit block 280 is located in front of the second one-way limit block 281. When the first one-way limit block 280 is pushed forward, it can slide downward, and when the second one-way limit block 281 is pushed backward, it can slide upward. Figure 6 As shown, the facing surfaces of the first one-way limit block 280 and the second one-way limit block 281 both have guide wedge surfaces, the guide wedge surface of the first one-way limit block 280 is on the top, and the guide wedge surface of the second one-way limit block 281 is on the bottom, and the ends of the two guide wedge surfaces that are away from each other are inclined toward their back-to-back surfaces.

[0053] A second spring 282 is connected between the first one-way limit block 280 and the second one-way limit block 281 and the partition. Initially, the second spring 282 prompts the first one-way limit block 280 to move upward and correspond to the upper push plate 220, and prompts the second one-way limit block 281 to move downward and correspond to the lower push plate 210. Teeth are arranged on the facing surfaces of the first one-way limit block 280 and the second one-way limit block 281, and a rotatable synchronous gear 290 is installed on the partition, and the synchronous gear 290 is clamped between the first one-way limit block 280 and the second one-way limit block 281.

[0054] During the feeding process, even if a lot of materials are put in and directly contact the upper push plate 220, the upper push plate 220 cannot move backward due to the obstruction of the first one-way limit block 280, and the lower push plate 210 moves backward to push the second one-way limit block 281 upward, and the second one-way limit block 281 drives the first one-way limit block 280 to move downward through the synchronous gear 290, so that the first one-way limit block 280 and the upper push plate 220 are gradually separated, and when the lower push plate 210 passes over the second one-way limit block 281, the upper push plate 220 passes over the first one-way limit block 280, and then the first one-way limit block 280 and the second one-way limit block 281 are reset under the action of the second spring 282. During the reset process of the device, the lower push plate 210 is blocked by the second one-way limit block 281, so the upper push plate 220 is reset first, and then the lower push plate 210 is reset. By setting the first one-way limit block 280 and the second one-way limit block 281, the scraper 240 can only be extended sequentially from bottom to top and then reset sequentially from top to bottom, further ensuring that the present invention can match the number of extended scrapers 240 according to the amount of material in the conveying pipeline 110, making the implementation of the present invention more reliable.

[0055] Further, such as Figure 3 As shown, a core column is arranged at the inner center of the main disk body 230, the upper push plate 220 and the lower push plate 210 are slidably arranged on the core column, and the second chain link is fixedly arranged on the core column.

[0056] In a further embodiment, each scraper 240 includes a first plate body and a second plate body, and the first plate body and the second plate body are slidably plugged in the circumferential direction. Figure 4 As shown, the first plate body and the second plate body are closely attached, and after the scraper 240 is extended, as shown in Figure 7 As shown, the first plate body and the second plate body are pulled apart by a certain distance, thereby ensuring that the outer peripheral wall of the scraper 240 can fit with the inner peripheral wall of the feed pipe 110. At the same time, because the first plate body and the second body are slidably plugged in, the sealing can still be ensured during the matching process of the outer peripheral wall of the scraper 240 and the inner peripheral wall of the feed pipe 110.

[0057] Further, such as Figure 4 and Figure 7 As shown, a push block 252 which can slide in the radial direction is arranged on the side of the main disk body 230 away from the forward direction, and the push block 252 corresponds to the push rod 250 one by one. The outer end of the push rod 250 and the inner end of the scraper 240 (the inner end is close to the center of the circle and the outer end is far from the center of the circle) can slide relative to each other, and the push rod 250 is slidably inserted into the push block 252. A third spring 251 is sleeved on the push rod 250, and the inner end of the third spring 251 is connected to the push rod 250, and the outer end is connected to the push block 252. Initially, the third spring 251 urges the push rod 250 and the push block 252 to move away from each other.

[0058] By setting the push block 252 and the third spring 251, during the extension of the scraper 240, if there is material obstruction between the scraper 240 and the inner wall of the feed pipe 110, which makes it difficult for the scraper 240 to extend, the movement of the push rod 250 will compress the third spring 251, which will not affect the rotation of the first expansion ring 260 and the second expansion ring 261. At the same time, the compressed energy storage of the third spring 251 can increase the thrust on the scraper 240, making it easier for the scraper 240 to extend.

[0059] In a further embodiment, Figure 2 As shown, to facilitate the installation of the roller 231 and the scraper 240, a plurality of first mounting blocks are provided on the side of the main disk body 230 away from the forward direction. The first mounting blocks are arranged in groups of two and the two first mounting blocks in the same group are spaced apart from each other in the circumferential direction. The roller 231 is rotatably installed between the two first mounting blocks. A mounting column is provided on the inner side of the first mounting block. The same scraper 240 is located between two adjacent rollers 231 and its circumferential sides are slidably connected to the corresponding mounting columns. The connecting spring 241 is sleeved on the mounting column and the outer end is connected to the first mounting block and the inner end is connected to the scraper 240.

[0060] A second mounting block is disposed inside the roller 231 , and both circumferential side walls of the scraper 240 are in sliding contact with the side walls of the corresponding second mounting block and the side walls of the roller 231 .

[0061] In a further embodiment, the driving device 100 includes a box body, a sprocket is arranged inside the box body, the sprocket is meshed with the conveying chain 120, and the driving device 100 also includes a driving motor for driving the sprocket to rotate. The conveying pipeline 110 can be arranged according to actual needs, and can be used for horizontal conveying or lifting conveying. Figure 1 In the embodiment of the feed pipe 110 given in , the feed pipe 110 has a horizontal section and a raised section, and the setting position of the feed port 130 is lower than the setting position of the discharge port 140. Naturally, the position of the discharge port 140 can also be set according to actual needs.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
