Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to an extrusion device for bullfrog feed production. Background Technology

[0002] Extrusion is a processing method in which starchy materials are heated and pressurized, and then the pressure and heat source are removed, causing them to cool and expand. Extrusion involves high-temperature treatment and various mechanical actions that break down and soften the cell walls of the fibrous structure, causing the starch to gelatinize and the proteins to become textured, which is beneficial for animal digestion and absorption, and significantly improves the digestibility and utilization of feed. Existing extrusion devices used in bullfrog feed production employ small-diameter discharge valves or pipes to discharge the feed after heating and cooking.

[0003] As disclosed in announcement number CN215775447U, a green and environmentally friendly extrusion device for bullfrog feed production includes a base plate. Vertical plates are fixedly installed on both sides of the bottom of the base plate. Fixed rods are fixedly installed above the opposite sides of the two vertical plates. A crushing chamber is fixedly installed between the two fixed rods. A connecting pipe is fixedly connected to the bottom of the crushing chamber, and the bottom end of the connecting pipe is fixedly connected to the chamber. A discharge pipe is fixedly inserted into the bottom of the chamber. Through the coordinated use of the base plate, vertical plates, first sliding rod, stirring shaft, transmission mechanism, cam plate, fixed block, motor, horizontal plate, first bevel gear, second bevel gear, fixed rod, crushing chamber, feed hood, connecting pipe, air inlet pipe, spring, second sliding rod, vertical stirring rod, discharge pipe, chamber, crushing blades, crushing shaft, and vertical shaft, the rotating crushing blades inside the crushing chamber crush the bullfrog feed, breaking down overly large feed particles into smaller ones.

[0004] The aforementioned technology involves pre-crushing the feed, then stirring and heating it with steam for maturation. After discharge, the feed is cooled and expanded. The matured bullfrog feed is discharged through a discharge pipe at the bottom of the container. However, this existing discharge method has the following drawbacks: the small diameter of the discharge pipe easily causes blockages in the matured bullfrog feed, making it difficult to discharge smoothly and quickly. This results in problems such as easy blockage, difficulty in discharging feed, and low discharge efficiency. Therefore, an extrusion device for bullfrog feed production is proposed to solve the above-mentioned problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] like Figures 1 to 4 As shown in this embodiment, an extrusion device for bullfrog feed production includes:

[0036] The box 1 has an opening at the bottom and L-shaped supports 104 are fixedly connected to both sides of it.

[0037] The base 105 is connected to the bottom of two L-shaped supports 104;

[0038] A steam dispersion inlet assembly is connected and fixed on the left side of the housing 1; the steam dispersion inlet assembly is used to disperse and supply high-temperature steam into the housing 1 after connecting to an external high-temperature steam supply pipeline or equipment.

[0039] The round tube 2 is connected and fixed to the top of the box 1, and the top left side of the tube is connected and fixed to an inclined feed pipe 201. The top of the feed pipe 201 is set as a funnel-shaped structure.

[0040] The U-shaped seat 202 is fixedly connected to the top of the round tube 2;

[0041] The rotating upper crushing and lower stirring assembly is installed on the U-shaped seat 202 and located inside the round tube 2 and the box 1. The rotating upper crushing and lower stirring assembly is used to pre-crush the clumped bullfrog feed raw materials and to rotate and stir them after crushing. The rotation and stirring are combined with the dispersed supply of high-temperature steam to ensure the uniform contact between the feed and the steam, so as to ensure the drying and maturation speed of the feed.

[0042] The unsealing and feeding component is installed between the top of the U-shaped seat 202 and the bottom of the box 1, and is rotatably fitted inside the rotating upper crushing and lower stirring component; the unsealing and feeding component is used to unseal a large area of ​​the bottom of the box 1 to prevent the feed from being blocked and to quickly discharge the dried and cooked feed.

[0043] Furthermore, the base 105 is fixedly connected to the bottom of the two L-shaped supports 104 by welding.

[0044] Furthermore, such as Figure 1 and 2As shown, the steam dispersion entry component includes a steam distribution box 101, a steam supply pipe 103, and an air blowing pipe 102. The steam distribution box 101 is fixedly connected to the left side of the housing 1. The steam supply pipe 103 is connected and fixed to the left side of the steam distribution box 101. There are multiple air blowing pipes 102 arranged in an array and connected and fixed to the right side of the steam distribution box 101. The right ends of the multiple air blowing pipes 102 extend into the housing 1.

[0045] In this embodiment, the steam distribution box 101, the steam supply pipe 103 and the blowing pipe 102 work together. When high-temperature steam is supplied after the steam supply pipe 103 is connected to an external high-temperature steam supply pipeline or equipment, the high-temperature steam enters the steam distribution box 101 and is then distributed into the housing 1 through multiple blowing pipes 102.

[0046] Furthermore, such as Figure 2 and 3 As shown, the rotating upper crushing and lower stirring assembly includes a rotating tube 3, stirring rods 301, crushing blades 302, an outer gear ring 303, a gear 304, and a drive motor 305. The rotating tube 3 is rotatably embedded in the bottom of the U-shaped seat 202. There are multiple stirring rods 301, which are fixedly connected to the outside of the rotating tube 3 and located inside the housing 1. There are multiple crushing blades 302, which are fixedly connected to the outside of the rotating tube 3 and located inside the round tube 2. The outer gear ring 303 is fixedly sleeved on the top of the outside of the rotating tube 3 and located inside the U-shaped seat 202. The gear 304 meshes with the right side of the outer gear ring 303. The drive motor 305 is fixedly installed on the top right side of the U-shaped seat 202, and the bottom end of its output shaft is fixedly connected to the top of the gear 304.

[0047] In this embodiment, a through hole is provided at the bottom of the spiral seat 202, and a second bearing is fixedly sleeved in the through hole. The inner ring of the second bearing is fixedly sleeved with the outer side of the rotating tube 3. The rotating tube 3 is rotatably embedded in the bottom of the spiral seat 202 through the second bearing, which achieves the effect of rotating and installing the rotating tube 3.

[0048] In this embodiment, the rotating tube 3, stirring rod 301, crushing blade 302, external gear ring 303, gear 304, and drive motor 305 work together. The drive motor 305 drives the gear 304 to rotate, and the gear 304 drives the rotating tube 3 to rotate through the meshing external gear ring 303. The rotating tube 3 drives multiple crushing blades 302 and multiple stirring rods 301 to rotate. The rotation of the crushing blades 302 is used to pre-crush the clumped bullfrog feed raw materials. The rotation of the stirring rods 301 is used to evenly stir the crushed bullfrog feed raw materials that enter the heated chamber 1. The mixing and dispersion of high-temperature steam ensures uniform contact between the feed and the steam, thereby ensuring the drying and maturation speed of the feed.

[0049] It should be noted that since gear 304 meshes with the right side of external gear ring 303, the rotating gear 304 can drive external gear ring 303 to rotate. This technology is a mature transmission technology.

[0050] Furthermore, such as Figure 2 , 3 As shown in Figure 4, the unsealing and unloading assembly includes a horizontal bar 4, a sealing plate 401, a vertical bar 402, a connecting rod 403, a vertical guide sleeve 404, and an electric telescopic rod 405. The top of the horizontal bar 4 is set with an arc-shaped structure and is fixedly connected between the front and rear inner walls of the box 1. There are two sealing plates 401, which are rotatably installed at the bottom of the box 1. The vertical bar 402 is located between the two sealing plates 401. The horizontal bar 4 is slidably sleeved on the vertical bar 402. There are two connecting rods 403, which are arranged obliquely and symmetrically. The two connecting rods 403 are respectively hinged between the bottom of the corresponding sealing plate 401 and the outside of the vertical bar 402. The vertical guide sleeve 404 is rotatably sleeved in the rotating tube 3 and slidably sleeved on the vertical bar 402. The electric telescopic rod 405 is fixedly installed on the top of the U-shaped seat 202, and the extended end of the electric telescopic rod 405 is fixedly connected to the top of the vertical bar 402.

[0051] In this embodiment, the bottom of the housing 1 is rectangularly fixedly connected to four supports, all located below the crossbar 4. The same stainless steel shaft is fixedly connected between two opposing supports. A circular through hole is opened on the front side of the sealing plate 401 near the vertical bar 402. Two first bearings are fixedly sleeved between the inner side of the circular through hole and the corresponding stainless steel shaft, which serves to rotate the sealing plate 401. A sealing gasket is glued and fixed to the top of the sealing plate 401. The top of the sealing gasket is pressed tightly against the bottom of the housing 1 and the bottom of the crossbar 4, which serves to seal the bottom of the housing 1 from the top of the sealing plate 401.

[0052] In this embodiment, two third bearings are fixedly sleeved inside the rotating tube 3. The inner ring of the third bearing is fixedly sleeved with the outer side of the vertical guide sleeve 404. The vertical guide sleeve 404 is rotatably sleeved inside the rotating tube 3 through the two third bearings. By using the rotatable sleeve connection, the phenomenon of transmitting rotational torque to the vertical guide sleeve 404 when the rotating tube 3 rotates is prevented, thereby avoiding the vertical rod 402 from being affected by rotational torque. In addition, a rectangular guide hole is opened at the top of the horizontal rod 4. The horizontal rod 4 is slidably sleeved on the outside of the vertical rod 402 through the rectangular guide hole, which has the effect of guiding the vertical sliding of the vertical rod 402.

[0053] In this implementation scheme, the horizontal bar 4, sealing plate 401, vertical bar 402, connecting rod 403, vertical guide sleeve 404, and electric telescopic rod 405 work together. The two sealing plates 401 seal the bottom of the box 1 during use. The electric telescopic rod 405 drives the vertical bar 402 to move downward. The vertical bar 402 slides downward within the horizontal bar 4 and vertical guide sleeve 404. The vertical bar 402 is pulled by the two connecting rods 403, which drive the two sealing plates 401 to rotate downward synchronously and open, thus removing the large area of ​​obstruction to the bottom of the box 1. This allows the dried and cooked feed to be discharged quickly and without blockage through a large-area channel, avoiding the problems of easy blockage, difficulty in feed discharge, and low discharge efficiency caused by the existing small-diameter discharge pipe. This improves the discharge efficiency and stability. After discharge, the feed expands during cooling.

[0054] It should be noted that, for the power supply of the electric telescopic pole 405 and the drive motor 305, since there is no lack of power supply measures at the bullfrog feed production and processing plant, the power supply is based on the existing mains power supply resources on site. The power supply circuit is formed by using the mains power cables on site and connecting them to the power input interface of the above-mentioned electrical components through conventional power distribution devices such as the power cords of the electrical components. This provides power supply for the conventional on-site cable foundation connection. These are all conventional, mature and well-known methods, and will not be described in detail here.

[0055] This embodiment can pre-crush clumps of raw materials when adding bullfrog feed, and ensure uniform contact between the feed and steam by mixing and dispersing the high-temperature steam. This ensures the drying and maturation speed of the feed, and facilitates the removal of the large area covering the bottom of the box 1 after maturation. This allows the dried and matured feed to be discharged quickly and smoothly through a large-area channel, avoiding the problems of easy clogging, difficulty in discharging feed, and low discharge efficiency caused by the existing small-diameter discharge pipes. This improves discharge efficiency and stability.

[0056] The usage method of this embodiment is as follows: When using the bullfrog feed production puffing device, start the drive motor 305 to drive the gear 304 to rotate. The gear 304 drives the rotating tube 3 to rotate through the meshing external gear ring 303. The rotating tube 3 drives multiple crushing blades 302 and multiple stirring rods 301 to rotate. When the bullfrog feed raw materials are added through the feed pipe 201, they first enter the round tube 2. At this time, the multiple rotating crushing blades 302 pre-crush the added bullfrog feed raw materials to reduce the phenomenon of clumping affecting the subsequent stable heating and cooking. The stirring rods 301 are used to uniformly stir the crushed bullfrog feed raw materials that enter the heating chamber 1. When the steam supply pipe 103 is connected to the external high-temperature steam supply pipeline or equipment to supply high-temperature steam, the high-temperature steam enters the gas distribution box 101 and is then dispersed into the chamber 1 through multiple air blowing pipes 102. By using the method of stirring and dispersing the high-temperature steam supply, the uniform contact between the feed and the steam is ensured, so as to ensure the drying and cooking speed of the feed.

[0057] After maturation, once the high-temperature steam supply is stopped, a receiving box for receiving material is placed below the box 1. Personnel activate the electric telescopic rod 405 in the forward direction, causing it to drive the vertical rod 402 downwards. The vertical rod 402 slides downwards within the horizontal rod 4 and the vertical guide sleeve 404. The vertical rod 402, through two connecting rods 403, pulls and simultaneously rotates the two sealing plates 401 downwards, opening them directly and completely removing the large area obstruction to the bottom of the box 1. This allows the dried and matured feed to be discharged quickly and smoothly through a large-area channel, avoiding the problems of easy clogging, difficulty in feed discharge, and low discharge efficiency associated with existing small-diameter discharge pipes. This improves discharge efficiency and stability. After discharge, the feed expands during cooling. After discharge, the electric telescopic rod 405 is activated in the reverse direction, causing it to drive the vertical rod 402 upwards. The vertical rod 402 drives the two connecting rods 403 to rotate and press the two sealing plates 401 upwards. Under the pressing force, the two sealing plates 401 rotate upwards again, sealing the bottom of the box 1 once more, allowing for reuse.

[0058] Example 2

[0059] like Figure 5 As shown, this embodiment differs from Embodiment 1 in that: the base 105 is detachably connected to the bottom of two L-shaped supports 104, and rectangular sleeves 106 are fixedly connected to both sides of the top of the base 105. The bottoms of the two L-shaped supports 104 are respectively movably fitted into the corresponding rectangular sleeves 106 and in movable contact with the top of the base 105. Two knob bolts 107 are pressed into contact on the opposing sides of the two L-shaped supports 104. Two threaded holes are opened on the opposing sides of the two rectangular sleeves 106, and the knob bolts 107 are threaded into the corresponding threaded holes.

[0060] This embodiment allows for the separate assembly and disassembly of the base 105, enabling personnel to replace it with a wheeled bracket or a bracket of different heights as needed. This further provides the effect of flexibly replacing the lower support components according to on-site requirements, thereby improving the flexibility of application.

[0061] The usage method of this embodiment is as follows: The difference from Embodiment 1 is that it also has the following functions: The rectangular sleeve 106 and the knob bolt 107 enable the base 105 to be detached. Subsequently, the personnel can rotate the knob bolt 107 in the opposite direction to separate it from the corresponding L-shaped support 104, thereby releasing the lock on the rectangular sleeve 106 and realizing the disassembly of the base 105. The detachable nature of the base 105 allows the personnel to replace the wheeled bracket or the bracket of different heights as needed, thereby further providing the effect of flexibly replacing the lower support component according to the site requirements and improving the flexible application effect.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
