Description

A feed steaming device with uniform feeding speed Technical Field

[0001] This invention relates to the field of feed processing technology, and in particular to a feed steaming device that provides uniform feed feeding. Background Technology

[0002] In animal husbandry, steaming feed is a key step in improving feed digestibility and ensuring animal health.

[0003] Traditional steaming devices often result in undercooked feed in some areas due to insufficient steam penetration, affecting feed quality. Furthermore, existing technologies cannot control the uniform extrusion of feed, and the conveyor belt only serves as a transport tool without integrated heating, leading to insufficient heating of the feed bottom contact surface, further exacerbating the risk of incomplete steaming. These shortcomings limit the efficiency and consistency of feed processing and increase breeding costs. Therefore, it is necessary to propose a feed steaming device with uniform feed feeding to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a feed steaming device with uniform feeding speed, which integrates a chopping and uniform feeding mechanism to ensure that the feed is uniformly chopped and stably conveyed before entering the steaming chamber, avoiding material accumulation; combined with a steam generator and a steam pipe at the bottom of the conveyor belt, it achieves the effect of uniform heating of the feed in all directions.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a feed steaming device with uniform feeding speed, comprising a base plate and a screw feeder and a feed conveyor disposed on the upper part of the base plate. The screw feeder has a feed inlet at the left end of its top and a discharge outlet at the right end. A feed processing chamber is disposed directly below the discharge outlet of the screw feeder. A chopping mechanism and a uniform extrusion mechanism are disposed inside the feed processing chamber. A steaming component is also disposed on the upper end face of the screw feeder. The uniform extrusion mechanism includes a turntable rotatably disposed on one side of the feed processing chamber. A rotating shaft is fixedly mounted on the turntable. Three pushing blades are rotatably disposed on the outer circumference of the rotating shaft. Multiple extrusion holes are equidistantly disposed on the lower end face of the feed processing chamber. The chopping mechanism can drive the rotating shaft and the turntable to rotate. A gear set for controlling the synchronous rotation of the three pushing blades is also disposed on the side of the feed processing chamber.

[0006] By adopting the above technical solution, the feed is first sent to the feed processing bin by the screw conveyor, and then further chopped by the chopping mechanism. The turntable and shaft rotate simultaneously, and under the drive of the gear set, the three pusher blades rotate while rotating on their own axis, which continuously pushes the chopped feed down. When the pusher blades are at the bottom, they are in a horizontal state and close to the extrusion hole, thus extruding the feed evenly and allowing it to fall onto the upper surface of the feed conveyor for transmission. The steaming component then steams the feed, allowing it to be better cooked and improving feed quality.

[0007] A further configuration of the present invention is that the gear set includes a gear ring fixed to the side wall of the feed processing bin, and the three pusher blades are equipped with rotating gears that mesh with the gear ring at one end extending to the outside of the turntable.

[0008] By adopting the above technical solution, when the turntable rotates, it drives the three pusher blades at the end and the rotating gear to rotate. Through the push of the gear ring, the pusher blades rotate simultaneously, thereby continuously pressing the feed down.

[0009] A further configuration of the present invention is as follows: the chopping mechanism includes two chopping rollers rotatably disposed at the top of the inner cavity of the feed processing bin, a motor for driving a chopping guide roller to rotate is fixedly mounted on one side of the feed processing bin, and the other ends of the two chopping rollers are provided with mutually meshing drive gears.

[0010] By adopting the above technical solution, a motor drives a chopping roller to rotate, and the two chopping rollers rotate relative to each other under the meshing of two drive gears, thereby further chopping the feed that falls in, making the subsequent steaming of the feed more uniform.

[0011] A further provision of the present invention is that a first synchronous belt structure is provided between the shredding roller and the rotating shaft, and a cutting assembly for cutting the extruded feed is provided at the bottom of the feed processing chamber.

[0012] By adopting the above technical solution, the shredder roller rotates while the first synchronous belt structure drives the rotating shaft and turntable to rotate, thereby enabling the uniform speed extrusion mechanism to operate.

[0013] A further provision of the present invention is that the cutting assembly includes a reciprocating screw and a guide rod installed at the bottom of the feed processing chamber, and the bottom of the feed processing chamber is also provided with a cutting blade that is helically connected to the reciprocating screw and slidably connected to the guide rod.

[0014] By adopting the above technical solution, as the feed is continuously extruded from the extrusion hole, the reciprocating screw is controlled to rotate. The guide rod slides back and forth, intermittently cutting the extruded feed, which facilitates subsequent steaming and processing. Both ends of the cutting blade are fixedly installed with sliders. A sliding shuttle is set in one of the sliders connected to the reciprocating screw. The spiral groove of the reciprocating screw cooperates with the slider and the sliding shuttle. The slider is embedded in the closed spiral groove of the screw, and the axial reciprocating motion is achieved by the thrust on the side of the spiral groove.

[0015] A further feature of the present invention is that a second synchronous belt structure is installed between the same end of the reciprocating lead screw and the rotating shaft, and a protective box is provided on the outside of both the reciprocating lead screw and the guide rod.

[0016] By adopting the above technical solution, while the shaft is rotating, the reciprocating screw is driven to rotate through the second synchronous belt structure, thereby realizing the back-and-forth sliding of the cutting blade to cut the feed evenly. The protective box can protect the guide rod and the reciprocating screw, making its operation safer and more stable.

[0017] A further provision of the present invention is that the steaming assembly includes a steam steaming machine installed on the upper end of the feed conveyor, and steam pipes are equidistantly arranged on the surface of the conveyor belt of the feed conveyor.

[0018] By adopting the above technical solution, the feed is extruded evenly and falls onto the feed conveyor and is conveyed to the right. Steam is generated by the steam cooker to cook the upper surface of the feed. At the same time, the steam pipe can heat and cook the lower surface of the feed, which can ensure that the feed is fully cooked and improve the quality of feed cooking.

[0019] A further provision of the present invention is that: steam transmission chambers are provided on both the left and right sides of the feed conveyor, the steam pipe connects the steam transmission chambers on both sides, an annular track connecting the end of the steam pipe is movably provided on the inner side of the steam transmission chamber, a steam conveying pipe is connected between the steam transmission chamber on one side and the steam cooking machine, and a drain pipe is provided at the end of the steam transmission chamber on the other side.

[0020] By adopting the above technical solution, part of the steam generated by the steam cooking machine is sent to the steam transmission chamber through the steam delivery pipe and reaches the steam pipe, so that the steam pipe can heat and cook the bottom of the feed, making it evenly heated. The steam and water are discharged through the drain pipe. The annular track is fixedly connected to the steam pipe, and the annular track can rotate in a ring on the side of the steam transmission chamber, so that the steam pipe can move with the conveyor belt on the surface of the feed conveyor.

[0021] A further provision of the present invention is that: a feed scraping mechanism is provided at the right end of the feed conveyor, the feed scraping mechanism includes a rotating rod rotatably disposed at the right end of the feed conveyor, a third synchronous belt is provided at the same end of the rotating rod and the rotating shaft, and three scrapers close to the end face of the feed conveyor and elastic components connecting the scrapers are provided on the outer circumference of the rotating rod.

[0022] By adopting the above technical solution, when the cooked feed is conveyed to the right end for feeding, the third synchronous belt drives the rotating rod to rotate, which in turn drives the scraper to scrape the surface of the conveyor belt, thereby scraping off the cooked feed and preventing the feed from sticking to the conveyor belt. The setting of the elastic component allows the scraper to better fit the surface of the conveyor belt, resulting in a better scraping effect.

[0023] A further embodiment of the present invention is that the elastic component includes a fixed rod circumferentially disposed outside the rotating rod, a spring is sleeved on the outer end of the fixed rod, and a movable block that is slidably connected to the fixed rod is fixedly mounted on the side of the scraper.

[0024] By adopting the above technical solution, the compressed spring pushes the movable block outward, causing the scraper to move away from the rotating shaft and clean the surface of the conveyor belt.

[0025] The beneficial effects of this invention are:

[0026] 1. The present invention uses a motor to drive a chopping roller to rotate, and under the meshing of two drive gears, the two chopping rollers rotate relative to each other, thereby further chopping the feed that falls in, making the subsequent steaming of the feed more uniform, and improving the steaming quality of the feed.

[0027] 2. In this invention, the shredding roller drives the turntable and the shaft to rotate simultaneously. Under the drive of the gear set, the three pushing blades rotate while rotating on their own axis, which can continuously push the shredded feed downwards. When the pushing blade is at the bottom, it is in a horizontal state and close to the extrusion hole, thereby extruding the feed evenly and making it fall onto the upper surface of the feed conveyor for transmission, so that the feed has better uniformity when it is steamed in the later stage.

[0028] 3. In this invention, as feed is continuously extruded from the extrusion hole, the reciprocating screw is controlled to rotate, and the guide rod slides back and forth to allow the cutting blade to cut the extruded feed intermittently, thereby facilitating subsequent steaming and processing and improving processing efficiency.

[0029] 4. In this invention, steam is generated by a steam cooking machine to cook the upper surface of the feed. Part of the generated steam is sent to the steam transmission chamber through a steam conveying pipe and reaches the steam pipe, so that the steam pipe can heat and cook the bottom of the feed, making it evenly heated.

[0030] 5. In this invention, when the steamed feed is conveyed to the right end for feeding, the third synchronous belt drives the rotating rod to rotate, which in turn drives the scraper to scrape the surface of the conveyor belt, thereby scraping off the cooked feed and preventing the feed from sticking to the conveyor belt. The elastic component allows the scraper to better fit the surface of the conveyor belt, resulting in a better scraping effect. Attached Figure Description

Detailed Implementation

[0041] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] As shown in Figures 1, 2, 3, and 4, a feed steaming device with uniform feeding includes a base plate 1, a screw feeder 2 mounted on the upper end of the base plate 1, and a feed conveyor 3. The screw feeder 2 has an inlet 21 at its left top and an outlet 22 at its right top. A feed processing chamber 4 is located directly below the outlet 22. The feed processing chamber 4 contains a chopping mechanism 5 and a uniform extrusion mechanism 6. A steaming component 7 is also mounted on the upper surface of the screw feeder 2. The uniform extrusion mechanism 6 includes components rotatably mounted within the feed processing chamber 4. A turntable 61 is located on one side, on which a rotating shaft 62 is fixedly mounted. Three pushing blades 63 are rotatably mounted on the outer circumference of the rotating shaft 62. Multiple extrusion holes are equidistantly arranged on the lower end face of the feed processing bin 4. The chopping mechanism 5 can drive the rotating shaft 62 and the turntable 61 to rotate. A gear set is also provided on the side of the feed processing bin 4 to control the synchronous rotation of the three pushing blades 63. The gear set includes a gear ring 64 fixed to the side wall of the feed processing bin 4. Rotating gears 65 that mesh with the gear ring 64 are installed at the ends of the three pushing blades 63 that extend to the outside of the turntable 61.

[0043] The feed is first fed into the feed processing bin 4 by the screw conveyor 2, and further chopped by the chopping mechanism 5. The turntable 61 and the rotating shaft 62 rotate simultaneously. Driven by the gear set, the three pusher blades 63 rotate while rotating on their own axis, continuously pushing the chopped feed downwards. When the pusher blades 63 are at the bottom, they are horizontal and close to the extrusion hole, thus extruding the feed evenly and allowing it to fall onto the upper surface of the feed conveyor 3 for transmission. The steaming component 7 steams the feed, allowing it to be better cooked and improving feed quality. When the turntable 61 rotates, it drives the three pusher blades 63 at the end and the rotating gear 65 to rotate. Driven by the gear ring 64, the pusher blades 63 rotate on their own axis, thus continuously pressing the feed downwards.

[0044] As shown in Figure 3, the chopping mechanism 5 includes two chopping rollers 51 rotatably disposed at the top of the inner cavity of the feed processing chamber 4. A motor 52 for driving one chopping guide roller 51 to rotate is fixedly mounted on one side of the feed processing chamber 4, and the other ends of the two chopping rollers 51 are provided with mutually meshing drive gears 53.

[0045] A motor 52 drives a shredding roller 51 to rotate, and under the meshing of two drive gears 53, the two shredding rollers 51 rotate relative to each other, thereby further shredding the feed that falls in, so that the subsequent feed is cooked more evenly.

[0046] As shown in Figures 4, 5, and 6, a first synchronous belt structure 66 is provided between one of the shredding rollers 51 and the rotating shaft 62. A cutting assembly for cutting the extruded feed is provided at the bottom of the feed processing chamber 4. The cutting assembly includes a reciprocating screw 67 and a guide rod 68 installed at the bottom of the feed processing chamber 4. A cutting blade 69 is also provided at the bottom of the feed processing chamber 4, which is helically connected to the reciprocating screw 67 and slidably connected to the guide rod 68. A second synchronous belt structure 611 is installed between the same end of the reciprocating screw 67 and the rotating shaft 62. A protective box 610 is provided on the outside of both the reciprocating screw 67 and the guide rod 68.

[0047] While the shredding roller 51 rotates, it drives the rotating shaft 62 and the turntable 61 to rotate via the first synchronous belt structure 66, thereby enabling the uniform speed extrusion mechanism 6 to operate. As the feed is continuously extruded from the extrusion hole, the reciprocating screw 67 is controlled to rotate. The sliding guide rod 68 allows the cutting blade 69 to slide back and forth, intermittently cutting the extruded feed, which facilitates subsequent steaming and processing. Both ends of the cutting blade 69 are fixedly installed with sliders. A sliding shuttle is set in one of the sliders connected to the reciprocating screw. The spiral groove of the reciprocating screw 67 cooperates with the slider and the sliding shuttle. The slider is embedded in the closed spiral groove of the screw. The axial reciprocating motion is achieved by the thrust on the side of the spiral groove. While the rotating shaft 62 is rotating, the reciprocating screw 67 is driven to rotate via the second synchronous belt structure 611, thereby enabling the cutting blade 69 to slide back and forth and cut the feed evenly. The protective box 610 can protect the guide rod 68 and the reciprocating screw 67, making its operation safer and more stable.

[0048] As shown in Figures 1 and 7, the steaming assembly 7 includes a steam steamer 71 installed on the upper end of the feed conveyor 3. Steam pipes 72 are equidistantly arranged on the surface of the conveyor belt of the feed conveyor 3. Steam transmission chambers 73 are provided on both the left and right sides of the feed conveyor 3. The steam pipes 72 connect the steam transmission chambers 73 on both sides. An annular track 74 connecting the end of the steam pipe 72 is movably arranged on the inner side of the steam transmission chamber 73. A steam conveying pipe 75 is connected between the steam transmission chamber 73 on one side and the steam steamer 71. A drain pipe 76 is provided at the end of the steam transmission chamber 73 on the other side.

[0049] The extruded feed falls evenly onto the feed conveyor 3 and is conveyed to the right. Steam is generated by the steam cooker 71 to cook the upper surface of the feed. At the same time, the steam pipe 72 can heat and cook the lower surface of the feed, ensuring that the feed is fully cooked and improving the quality of the feed cooking. Part of the steam generated by the steam cooker 71 is sent to the steam transmission chamber 73 through the steam delivery pipe 75 and reaches the steam pipe 72, so that the steam pipe 72 can heat and cook the bottom of the feed, making it evenly heated. Steam and water are discharged through the drain pipe 76. The annular track 74 is fixedly connected to the steam pipe 72 and can rotate in a ring on the side of the steam transmission chamber 73, so that the steam pipe 72 can move with the conveyor belt on the surface of the feed conveyor 3.

[0050] As shown in Figure 8, a feed scraping mechanism is provided at the right end of the feed conveyor 3. The feed scraping mechanism includes a rotating rod 77 rotatably disposed at the right end of the feed conveyor 3. A third synchronous belt 78 is provided at the same end of the rotating rod 77 and the rotating shaft 62. Three scrapers 79 close to the end face of the feed conveyor 3 are provided on the outer circumference of the rotating rod 77, and elastic components connecting the scrapers 79 are provided. The elastic components include a fixed rod 710 circumferentially disposed outside the rotating rod 77. A spring 711 is sleeved on the outer end of the fixed rod 710. A movable block 712 that is slidably connected to the fixed rod 710 is fixedly mounted on the side of the scraper 79.

[0051] When the cooked feed is conveyed to the right end for feeding, the third synchronous belt 78 drives the rotating rod 77 to rotate, which in turn drives the scraper 79 to scrape the surface of the conveyor belt, thereby scraping off the cooked feed and preventing the feed from sticking to the conveyor belt. The elastic component allows the scraper 79 to better fit the surface of the conveyor belt, resulting in a better scraping effect. The compressed spring 711 pushes the movable block 712 outward, moving the scraper 79 away from the rotating shaft 62 to clean the surface of the conveyor belt.
