Description

Technical Field

[0001] The invention relates to the technical field of feed feeding, and in particular to a feeding device for poultry feed processing. Background Art

[0002] Feeding in poultry feed processing refers to the process of adding various raw materials into feed processing equipment in a predetermined proportion for mixing, crushing and granulation.

[0003] Corn and beans (such as soybeans) are usually used as the main raw materials for the production of poultry feed such as chickens, ducks, and geese, of which corn accounts for 60%-70% and beans account for 30%-40%. In order to ensure the nutritional balance of the feed, these two raw materials need to be crushed into fine particles separately, and then mixed in a predetermined ratio to finally make feed pellets. However, when using a feed all-in-one machine to make feed, due to the different addition ratios of different raw materials, precise raw material configuration, crushing and mixing are required, which makes the ingredient preparation process before making feed more cumbersome, thereby increasing processing time and cost.

[0004] Based on the above situation, the present invention proposes a feeding device for poultry feed processing. Summary of the invention

[0005] In order to overcome the disadvantage of complicated raw material proportioning before feeding in feed processing, the present invention provides a feeding device for poultry feed processing.

[0008] In one embodiment, a side of the second contact switch close to the adjacent contact block is a non-contact surface, and a side of the second contact switch close to the adjacent contact surface of the first contact switch is a contact surface.

[0009] In one of the embodiments, there is also a material guide rack distributed corresponding to the lower barrel, and the material guide rack is arranged at the bottom of the cover plate.

[0010] In one of the embodiments, the middle of the material guide rack is arranged in a three-dimensional four-pointed star shape.

[0011] In one of the embodiments, it further includes a material guide plate distributed along the circumference of the material guide frame, the material guide plate is fixedly connected to the side of the material guide frame at an angle, and a U-shaped groove is opened in the middle of the material guide plate.

[0012] In one of the embodiments, a second spring is further included, which is distributed corresponding to the material guide frame. The material guide frame is slidably connected to the cover plate, and both ends of the second spring are respectively fixed to the corresponding material guide frame and the cover plate. The baffle is fixed with a pull rod, the material guide frame is fixed with a first magnetic block, the pull rod is fixed with a second magnetic block, and the second magnetic block is magnetically matched with the first magnetic block on the same side.

[0013] In one embodiment, the second magnetic block cooperates with the first magnetic block through repulsive magnetic forces.

[0014] In one of the embodiments, it also includes a material probe frame, which is slidably connected to the discharge barrel, and the baffle is fixedly connected to a reset frame, and the top of the reset frame is set as an inclined surface, and the inclined surface of the reset frame contacts the adjacent material probe frame. The baffle first drives the reset frame to move to the side away from the material probe frame, so that the inclined surface of the reset frame completely releases the limit on the material probe frame, and the baffle then moves to the edge of the square discharge hole of the discharge barrel, so that the discharge hole begins to be opened.

[0018] The present invention provides a second spring, a pull rod, a first magnetic block and a second magnetic block so that when the feed hole is opened, the guide frame can automatically move to the middle of the open position according to the degree of opening of the feed hole, so that the raw material feeding is more uniform and dispersed, avoiding concentrated feeding.

[0019] The present invention provides a material detection frame and a reset frame, so as to facilitate observation of which side of the discharge barrel has run out of raw materials and needs to be added, and which side of the discharge barrel has full raw materials and does not need to be added.

[0020] When the feeding speed of the lower barrel from the top is too fast and the discharging speed from the bottom is too slow, the material flows back into the conveying device of the raw material through the discharge pipe, thereby ensuring the smooth operation of the device and avoiding damage to the machine.

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Embodiment 1: A feeding device for poultry feed processing, such as Figures 1 to 3 As shown, it includes a control panel 2, which is fixedly connected to the front side of the granulator 1, and also includes a discharge barrel 4 symmetrically distributed along the left and right sides of the granulator 1, the discharge barrel 4 is fixedly connected to the top of the cover plate 3 of the granulator 1, and a square discharge hole is opened at the bottom of the discharge barrel 4, and a vibrating rod 5 is fixedly connected to the middle of the lower inner part of the discharge barrel 4, and a sliding rod 6 symmetrically distributed along the left and right sides of the discharge barrel 4 is fixedly connected to the bottom of the cover plate 3, and a baffle 7 is slidably connected between the adjacent sliding rods 6 on the same side along the front-to-back direction, and the baffle 7 is used to block the discharge holes of adjacent discharge barrels 4, and an electric push rod 8 corresponding to the baffle 7 is fixedly connected to the bottom of the cover plate 3, and the telescopic end of the electric push rod 8 is fixedly connected to the corresponding baffle 7.

[0035] First, the conveying pipes of the two raw materials are respectively connected to the left and right discharge barrels 4, so that the raw materials are conveyed to the discharge barrel 4 for pre-storage. Then, the control panel 2 is used to control the extension of the electric push rods 8 on the left and right sides, thereby driving the baffle 7 to slide and open along the slide bar 6, and the extension amount of the electric push rod 8 can be controlled by the control panel 2, so that the opening amount of the two baffles 7 corresponds to the ratio of the two raw materials. In this way, the two raw materials are fed into the granulator 1 in proportion. During the feeding period, the vibrating rod 5 is started to allow the raw materials in the discharge barrel 4 to be smoothly fed into the granulator 1. When the feeding is stopped, the control panel 2 is used to control the shortening of the electric push rods 8 on the left and right sides, thereby driving the baffle 7 to slide in the opposite direction along the slide bar 6 and close.

[0036] In summary, the present invention uses the control panel 2 and the electric push rod 8 as a control system to accurately control the discharge amount of each raw material to ensure accurate ratio. Moreover, by pre-storing raw materials in the discharge barrel 4, changes in the feeding amount can be buffered to ensure the stability of the discharge system and prevent ratio failure caused by fluctuations in the feeding amount. In addition, through the vibrating rod 5, the raw materials in the discharge barrel 4 can be discharged smoothly into the granulator 1 to prevent blockage.

[0037] like Figure 4 and Figure 5 As shown, it also includes a material storage box 9 corresponding to the discharge barrel 4, the material storage box 9 is fixedly connected to the corresponding discharge barrel 4, and the material storage box 9 is communicated with the corresponding discharge barrel 4, a slide 10 is slidably connected in the material storage box 9, and the side pressure of the raw material in the discharge barrel 4 causes the slide 10 to slide outward, and a first spring 11 symmetrically distributed along the front and back of the slide 10 is fixedly connected between the slide 10 and the adjacent material storage box 9, a contact block 12 is fixedly connected to the side of the slide 10 away from the discharge barrel 4, a first contact switch 13 is fixedly connected to the side of the material storage box 9 away from the discharge barrel 4, and the first contact switch 13 is electrically connected to the granulator 1 through the control module, and a fixed rod 14 is fixedly connected to the side of the material storage box 9 away from the discharge barrel 4, and a second contact switch 1 is rotatably connected to the fixed rod 14 5. The second contact switch 15 is electrically connected to the granulator 1 through the control module. The second contact switch 15 is located between the adjacent contact block 12 and the first contact switch 13. The side of the second contact switch 15 close to the adjacent contact block 12 is a non-contact surface, and the side of the second contact switch 15 close to the contact surface of the adjacent first contact switch 13 is a contact surface. The contact block 12 moves outward and first contacts with the non-contact surface of the second contact switch 15, and then contacts with the contact surface of the first contact switch 13. At this time, the granulator 1 is controlled to start. When the contact block 12 moves inward and resets, it contacts with the contact surface of the second contact switch 15. At this time, the granulator 1 is controlled to shut down. A torsion spring 16 is fixedly connected between the fixing rod 14 and the adjacent second contact switch 15.

[0038] During the feeding of raw materials through the discharge barrel 4, as the raw materials in the discharge barrel 4 gradually accumulate, the lateral pressure generated by the accumulation gradually increases, so that the slide 10 gradually slides outward along the material box 9, and the first spring 11 is gradually compressed. The slide 10 drives the contact block 12 to slide toward the side close to the adjacent first contact switch 13. During the sliding process, the contact block 12 will contact the non-contact surface of the adjacent second contact switch 15 and push the second contact switch 15 to rotate. The torsion spring 16 is deformed so that the contact block 12 can pass over the second contact switch 15. The torsion spring 16 is reset to drive the second contact switch 15 to reverse and reset. When the raw materials in the discharge barrel 4 are full, the lateral pressure is large enough to make the contact block 12 contact the contact surface of the first contact switch 13. At this time, the first contact switch 13 is opened, so that the granulator 1 is automatically started.

[0039] During the feeding process, as the raw materials in the lower barrel 4 are dynamically fed, the lateral pressure may change slightly, causing the first spring 11 to slightly expand and contract, thereby causing the contact block 12 to swing back and forth between the first contact switch 13 and the second contact switch 15. When the raw materials in the lower barrel 4 are less than a certain amount (usually when the raw materials are used up), the lateral pressure of the raw materials is lost, and the first spring 11 resets to drive the slide 10 to reset, thereby driving the contact block 12 to reset. During the resetting process, the contact block 12 contacts the contact surface of the second contact switch 15. At this time, the second contact switch 15 is opened, causing the granulator 1 to shut down and stop automatically.

[0040] In summary, the present invention realizes that the machine can only be started and used when the container is full of raw materials through the arrangement of components such as the contact block 12, the first contact switch 13, and the second contact switch 15, ensuring that the starting conditions for each unloading are consistent, avoiding inaccurate proportions due to excessive raw materials, and automatically stopping when the raw materials in the container are less than a certain amount, ensuring that the amount of raw materials is always within a safe range, avoiding proportion failure due to insufficient raw materials.

[0041] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 7 As shown, it also includes a guide frame 17 distributed corresponding to the lower barrel 4. The guide frame 17 is arranged at the bottom of the cover plate 3. The middle of the guide frame 17 is arranged in a three-dimensional four-pointed star shape. The front, back, left and right sides of the guide frame 17 are fixedly connected with guide plates 171, and a U-shaped groove is opened in the middle of the guide plate 171.

[0042] After the baffle 7 is opened, the raw materials in the discharge barrel 4 are evenly dispersed along the middle of the guide frame 17 to the guide plates 171 on the front, back, left and right sides, and then fed into the granulator 1 through the edge of the guide plate 171 and the U-shaped groove in the middle. In this way, the feeding is more evenly dispersed to avoid concentrated feeding.

[0043] like Figure 8 and Fig. 9As shown, it also includes a second spring 18 distributed corresponding to the guide frame 17, the guide frame 17 is slidably connected to the cover plate 3, and the two ends of the second spring 18 are respectively fixed to the corresponding guide frame 17 and the cover plate 3, a pull rod 19 is fixed to the side of the baffle 7 close to the adjacent second spring 18, a first magnetic block 20 is fixed to the side of the guide frame 17 close to the adjacent pull rod 19, and a second magnetic block 21 is fixed to the end of the pull rod 19, and the second magnetic block 21 cooperates with the first magnetic block 20 on the same side through repulsive magnetic forces.

[0044] Since the square discharge hole of the discharge barrel 4 needs to control the opening degree according to the raw material ratio, if the guide frame 17 is fixed below the center of the discharge hole, when the discharge hole is not fully opened, the guide frame 17 cannot play the effect of uniform material guidance. To avoid this situation, it is necessary to control the guide frame 17 to move with the opening of the discharge hole. The specific operation steps are as follows:

[0045] Initially, the top tip of the center of the guide frame 17 is located just below the side edge line of the square discharge hole of the discharge barrel 4 close to the adjacent electric push rod 8. During the movement and opening of the baffle 7, when the electric push rod 8 extends and pushes the baffle 7 to start moving until the square discharge hole is opened by one tenth, the baffle 7 drives the second magnetic block 21 to approach the magnetic force range of the first magnetic block 20. At this time, through the repulsive magnetic force, the first magnetic block 20 drives the guide frame 17 to slide to the side of the compressed second spring 18 to half of the opened part of the discharge hole. Repeat, every time the discharge hole is opened by one tenth, the guide frame 17 slides to the half of the discharge hole that is opened, so that the top tip of the guide frame 17 is always located directly below the middle of the open part of the discharge hole, until the square discharge hole is fully opened. At this time, the top tip of the guide frame 17 is located directly below the square discharge hole of the discharge barrel 4. In this way, the guide frame 17 can move to the middle of the open position by itself according to the degree of opening of the discharge hole, so that the raw material feeding is more uniform. When the baffle 7 is reset, the second spring 18 is reset to drive the guide frame 17 to slide and reset.

[0046] Embodiment 3: Based on embodiment 1, Fig.10 As shown, it also includes a material probe frame 22, which is slidably connected to the discharge barrel 4, a reset frame 23 is fixedly connected to the top of the baffle 7, and the reset frame 23 is slidably connected to the cover plate 3. The top of the reset frame 23 is set as an inclined surface, and the inclined surface of the reset frame 23 contacts the adjacent material probe frame 22. The baffle 7 first drives the reset frame 23 to move to the side away from the material probe frame 22, so that the inclined surface of the reset frame 23 completely releases the limit on the material probe frame 22, and the baffle 7 then moves to the edge of the square discharge hole of the discharge barrel 4, so that the discharge hole begins to be opened.

[0047] When the lower barrel 4 is pre-stored with full of raw materials and the baffle 7 is opened, the baffle 7 drives the reset frame 23 to move away from the material detection frame 22, and releases the limit of the inclined surface of the reset frame 23 on the material detection frame 22, so that the material detection frame 22 is only limited by the support of the raw materials in the lower barrel 4. When the granulator 1 stops urgently, the material detection frame 22 on the lower barrel 4 where the raw materials are used up will obviously drop. In this way, it is convenient to observe which side of the lower barrel 4 has run out of raw materials and needs to be added, and which side of the lower barrel 4 is still full and does not need to be added. When the baffle 7 is reset, it drives the reset frame 23 to reset, thereby pushing the material detection frame 22 to reset.

[0048] like Fig.11 As shown, a discharge pipe 24 is also included. The discharge pipe 24 is connected to the outside of the lower barrel 4 and is inclined downward. A guide block 25 is fixedly connected to the inside of the lower barrel 4 and is located above the adjacent discharge pipe 24 .

[0049] If the feeding speed of the lower barrel 4 from the top is equal to or slightly faster than the discharging speed from the bottom, the raw materials will be smoothly fed along the guide block 25. If the feeding speed of the lower barrel 4 from the top is too fast and the discharging speed from the bottom is too slow, it may cause the entire device to run poorly and easily damage the machine. At this time, it can flow back into the raw material conveying device through the discharge pipe 24.
