Description

Technical Field

[0001] This invention belongs to the field of poultry feed technology, specifically relating to a production device that can improve the quality of laying hen feed. Background Technology

[0002] To better meet the needs of poultry growth and development and achieve scientific farming, the composition and form of feed vary at different growth stages. Currently, most poultry farms rely on purchased feed for daily feeding. On the one hand, the feed formula is controlled by the manufacturers, making precise management difficult; on the other hand, the price of finished feed is high, hindering cost control.

[0003] Based on multiple factors, many small and medium-sized farms have begun producing their own feed to achieve precise management and cost control throughout the entire process. However, current small-scale feed production equipment has the following problems: From a production process perspective, this equipment has a feed hopper with a grinding disc with extrusion holes at the bottom and a rotating pressure roller above it. Various raw materials are directly fed into the hopper and then extruded through the holes by the pressure roller. The production process is relatively rapid from feeding to discharging. Since different raw materials have different volumes and shapes, they are not mixed thoroughly before being formed, resulting in uneven nutrient composition in the feed. Furthermore, some larger raw materials lack sufficient density after forming and are prone to breakage, leading to waste during feeding.

[0004] From a performance perspective, taking a medium-scale farm with 10,000 laying hens as an example, the total amount of feed per hen per day varies from 100-150g. Ignoring losses, the average daily feed volume can reach 1000-1500kg. However, the single-machine capacity of small-scale feed production equipment is only 400-500kg / h. Assuming a single feed intake of 40-50kg, manual feeding is required 8-10 times per hour, totaling 24-30 manual feedings, which is time-consuming and labor-intensive.

[0005] In conclusion, traditional small-scale feed production equipment and processes are not ideal and urgently need further optimization. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a production device that can improve the quality of laying hen feed, which can not only reduce the labor intensity of workers, but also improve the quality of the finished feed.

[0007] This invention is implemented as follows: a production apparatus capable of improving the quality of laying hen feed, comprising: A mixing device for mixing various raw materials, the mixing device having mixing blades that rotate about a horizontal axis; A feeding device for conveying raw materials into the mixing device, the feeding device having feeding auger blades; A crushing device for crushing uniformly mixed raw materials, the crushing device having a pair of cutters that rotate synchronously in opposite directions about a horizontal axis; A conveying device for feeding uniformly mixed raw materials into the crushing device, the conveying device having conveying auger blades; A forming device for granulating crushed raw materials, the forming device having a hopper with extrusion holes on the side and a pressure knife rotating about a vertical axis inside the hopper. Inclined chute for conveying crushed raw materials into the forming device.

[0008] Furthermore, the crushing device also includes a casing, a crushing motor, a reduction gear set, and a roller gear set; The top of the casing is used for feeding, and the bottom is used for discharging. The cutters are installed opposite each other inside the casing, and their shafts are connected by the roller gear set. The crushing motor is installed on the side of the casing, and its shaft is connected to the shaft of one of the cutters by the reduction gear set.

[0009] Furthermore, the cutting blade is divided into even-numbered blades and odd-numbered blades. The even-numbered blades have 2n main blades and 2n-1 auxiliary blades, and the odd-numbered blades have 2n-1 main blades and 2n auxiliary blades. The main blades and auxiliary blades are arranged alternately in the axial direction. The outer diameter of the main blade is larger than the outer diameter of the auxiliary blade, so that the main blades on the two cutting blades are inserted into the groove formed by the two adjacent main blades, and the distance between the maximum outer circle of the main blade and the maximum outer circle of the auxiliary blade in the groove is not greater than 2mm.

[0010] Furthermore, the main blade has a plurality of cutting teeth evenly distributed in the circumferential direction, and the secondary blade has a plurality of cutting grooves evenly distributed in the circumferential direction, the depth of the cutting grooves being no greater than 2mm.

[0011] Furthermore, the crushing device also includes a baffle plate, which is disposed on the top of the housing and above the cutter, and has a slot that matches the shape of the cutter.

[0012] Furthermore, the molding device also includes a molding motor, a distributing hopper, and extrusion plates. The side of the material box is provided with evenly distributed perforations along the circumferential direction. Multiple extrusion plates are provided and correspondingly installed at the perforations. The inner side of the extrusion plate is an arc surface that matches the inner wall of the material box. The extrusion plate is provided with a number of extrusion holes. The distributing hopper is installed on the outside of the material box and corresponds to the position of each extrusion plate. The molding motor is installed at the bottom of the material box and its main shaft is connected to the pressure knife.

[0013] Furthermore, the diameter of the extrusion orifice of each of the extrusion plates is different.

[0014] Furthermore, the front side of the pressure knife, which is in the same direction as the rotation direction, is an extrusion surface. The extrusion surface is curved, and the distance between the surface and the rotation center increases sequentially from the inside to the outside.

[0015] Furthermore, the feeding inlet of the feeding device is equipped with a storage bin.

[0016] The beneficial effects of this invention are: (1) The present invention uses a stirring device to fully mix all raw materials in advance to ensure that the proportion of each component in the finished feed is as consistent as possible with the theoretical proportion, thereby ensuring the growth and development of poultry; a crushing device is used to further crush the large raw materials into smaller pellets, so that the subsequent molding process can be squeezed and compacted, avoiding the waste caused by broken material; a molding device is used to compress the pellets into feed of a specific shape, and the discharge method is side discharge, which can reduce waste and facilitate maintenance.

[0017] (2) The stirring device in this invention adopts the horizontal stirring principle, which avoids the material stratification phenomenon caused by vertical stirring, thereby improving the uniformity of the mixture. The capacity can reach 1 cubic meter, corresponding to a raw material weight of 500 kg, effectively reducing the number of shutdowns.

[0018] (3) The crushing device in this invention adopts the principle of opposing double blade cutting, which can crush large-volume raw materials into small-volume raw materials rather than powder, thereby meeting the compactness requirements of subsequent molding.

[0019] (4) The molding device in this invention uses a replaceable extrusion plate, which is easy to maintain and can customize feed of different sizes according to the poultry development stage, so as to achieve precise management of the whole life cycle. In addition, since the principle is crushed, the extrusion force can be reduced, thereby reducing the thickness of the extrusion plate and making the feed form relatively stable granular particles.

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0023] like Figures 1 to 8 As shown, a production device for improving the quality of laying hen feed includes a mixing device 1, a feeding device 2, a crushing device 3, a conveying device 4, an inclined slide 5, and a forming device 6.

[0024] The feeding device 2 is an auger conveyor, which has feeding auger blades located between the feeding port and the discharging port. The rotation axis of the feeding auger blades is inclined at a certain angle to the horizontal plane, thereby conveying the raw material in the feeding port to a certain height and then discharging it from the discharging port. To increase the feeding capacity, a storage tank 7 is also installed at the feeding port. After all the raw material is poured into the storage tank 7, it is conveyed to the next stage by the feeding auger blades. The storage tank 7 can hold at least 100 kg of material, which can significantly improve the continuity of the overall process.

[0025] The mixing device 1 includes a mixing tank 8 and rotating mixing blades mounted inside the mixing tank 8, with the rotation axis of the mixing blades parallel to the horizontal plane. The mixing tank 8 has a capacity of 1 cubic meter and can hold 500 kg of raw materials. Based on a daily output of 1500 kg, only three additions are needed. An electric valve is installed at the bottom of the mixing tank 8, controlling discharge via an electrical signal. The advantage of this horizontal mixing method is that it can thoroughly and continuously agitate the solid materials inside the tank, preventing stratification due to differences in density and size, and improving the uniformity of the raw materials. A feed inlet is located at one end of the top of the mixing tank 8, and a discharge outlet is located at the other end of the bottom. The discharge port of the feeding device 2 is connected to the feed inlet of the mixing tank 8, enabling continuous conveying of the raw materials.

[0026] The conveying device 4 is the same as the feeding device 2, and it has conveying auger blades located between the feeding port and the discharging port. The rotation axis of the conveying auger blades is inclined at a certain angle to the horizontal plane, so as to convey the raw material in the feeding port to a certain height and then discharge it from the discharging port. The feeding port of the conveying device 4 is located below the discharge port of the mixing tank 8, so as to receive the uniformly mixed raw material discharged from the mixing tank 8 and convey it to the next stage by the conveying auger blades.

[0027] like Figures 2-5 As shown, the crushing device 3 includes a housing 10, a cutter 11, a crushing motor 12, a reduction gear set 13, and a roller gear set 14.

[0028] The top of the casing 10 is open, located below the discharge port of the conveying device 4. The bottom of the casing 10 is also open for material discharge. Cutters 11 are mounted opposite each other inside the casing 10, with their rotation axes parallel to the horizontal plane. Their shafts are connected via a roller gear set 14. The crushing motor 12 is mounted on the side of the casing 10, and its shaft is connected to the shaft of one of the cutters 11 via a reduction gear set 13. The roller gear set 14 consists of two gears with equal teeth, enabling the two cutters 11 to rotate synchronously in opposite directions. The reduction gear set 13 consists of two gears, one large and one small, thereby reducing the rotational speed while increasing the torque to achieve material crushing.

[0029] To break larger raw materials such as corn into smaller particles, the cutter 11 employs a staggered cutting principle. Specifically, the cutter 11 consists of even-numbered cutters 15 and odd-numbered cutters 16. Even-numbered cutters 15 have 2n main cutters 17 and 2n-1 auxiliary cutters 18, while odd-numbered cutters 16 have 2n-1 main cutters 17 and 2n auxiliary cutters 18. In a preferred example, n=2. The main cutters 17 and auxiliary cutters 18 are staggered axially. The outer diameter D1 of the main cutter 17 is larger than the outer diameter D2 of the auxiliary cutter 18, ensuring that the main cutters 17 on the two cutters 11 are inserted into the grooves formed by two adjacent main cutters 17, and the distance between the maximum outer diameter of the main cutter 17 and the maximum outer diameter of the auxiliary cutter 18 in the groove is no more than 2mm. The distance between the sidewall of the main cutter 17 on the even-numbered cutter 15 and the sidewall of the adjacent auxiliary cutter 18 on the odd-numbered cutter 16 should be as small as possible to prevent them from contacting and affecting rotation. After the raw material falls onto the cutter 11, it is shredded into smaller particles as the cutter 11 rotates continuously. Since the radius of the main cutter 17 is larger than that of the secondary cutter 18, and both rotate at the same speed, the linear velocity of the outer circle of the main cutter 17 is greater than that of the outer circle of the secondary cutter 18. Therefore, when the main cutter 17 cuts the raw material, it also provides a tangential pulling force, thereby better separating the raw material and avoiding the situation of cutting without breaking.

[0030] Furthermore, such as Figure 5 As shown, the main blade 17 has a plurality of circumferentially distributed cutting teeth 19, and the secondary blade 18 has a plurality of circumferentially distributed cutting grooves 20, the depth of which is no greater than 2 mm. The tips of the cutting teeth 19 are arranged along the circumferential direction, and their leading edges form grooves, the groove surfaces of which extend to the trailing edge of the previous cutting tooth 19. The function of the cutting grooves 20 is to provide surface friction, thereby enabling the raw material to be crushed in a relatively fixed manner and preventing slippage.

[0031] To prevent raw materials from falling directly from the outside of the cutter 11 without being crushed, the crushing device 3 also includes a baffle plate 21. The baffle plate 21 is located on the top of the housing 10 and above the cutter 11, and has a slot 22 that matches the shape of the cutter 11. The baffle plate 21 is made of a relatively soft material, such as rubber. A channel for the raw materials to fall is formed between the two baffle plates 21, allowing the raw materials to fall onto the cutter 11. Obviously, the surface of the baffle plate 21 should be vertical and coplanar with the rotation center of the cutter 11.

[0032] The inclined slide 5 is set at an angle, and its top feed port is located below the bottom of the crushing device 3 to receive the crushed raw materials.

[0033] The forming device 6 includes a material box 23, a pressure knife 24, a forming motor 25, a distribution hopper 26, and an extrusion plate 27. The top of the material box 23 is also open and is located below the bottom discharge port of the inclined slide 5, for receiving crushed raw materials.

[0034] The material box 23 is a cylindrical structure with evenly distributed perforations 28 on its side. The extrusion plate 27 is an arc-shaped plate with the same curvature as the inner wall of the material box 23, thus forming a complete inner circular surface. Multiple extrusion plates 27 are provided and correspondingly installed at the perforations 28. Both ends of the extrusion plate 27 and the ends of the perforations 28 are mutually matching stepped structures. The extrusion plate 27 is inserted into the perforations 28 from the outside, and the stepped structures at both ends are fixed to the stepped structures at both ends of the perforations 28 using screws 29 to form a fixed installation. The extrusion plate 27 has several arrayed extrusion holes 30. Because the extrusion plate 27 is installed from the outside, maintenance can be performed without disassembling other parts, making maintenance easier.

[0035] A rotating shaft 31 is installed in the center of the feed hopper 23. A boss 32 is provided on the rotating shaft 31. A central hole 33 is provided in the center of the pressure knife 24. The rotating shaft 31 passes through the central hole 33, and the pressure knife 24 is fixed to the boss 32 of the rotating shaft 31 by a locking nut 34, thus achieving a rotatable installation. A feed hopper 26 is installed on the outside of the feed hopper 23, corresponding to the position of each extrusion plate 27. After the pressure knife 24 extrudes the raw material from the extrusion hole 30, the shaped feed falls onto the corresponding feed hopper 26 and finally slides into the feed collection bucket. The forming motor 25 is installed at the bottom of the feed hopper 23, and its main shaft is connected to the bottom end of the rotating shaft 31. It should be noted that different poultry and different growth and development stages have different requirements for feed form. Taking laying hens as an example, the feed form for chicks is mostly small pellets for easy swallowing. The feed form for growing hens is mostly medium-sized pellets. The feed form for laying hens is mostly large pellets to reduce waste and stimulate feed intake. Therefore, to address this situation, the diameter of the extrusion orifice 30 on each extrusion plate 27 is different. This means that if a farm raises poultry at different developmental stages simultaneously, the feed form can be adjusted to produce feed of different sizes. The specifications of the extrusion orifices 30 on the extrusion plate 27 range from 1mm to 5mm, and the orifices 30 are conical, wider at the inside and narrower at the outside, making it easier to extrude and granulate when the pressure knife 24 rotates.

[0036] As a preferred example, the pressure knife 24 has two centrally symmetrically arranged extrusion sections. The front side of the extrusion section, which is in the same direction as the rotation direction, is the extrusion surface 9. The extrusion surface 9 is curved, and the distance between this surface and the rotation center increases from the inside to the outside. That is, when the pressure knife 24 rotates, the space between the front side and the inner wall of the material box 23 decreases from front to back with the rotation direction. Therefore, the raw material will gradually be subjected to greater extrusion pressure and eventually be extruded from the extrusion hole 30 to form a shape.

[0037] The working process and principle of this utility model S1. Select a predetermined quantity of raw materials. The specific formula for the raw materials is detailed in the solid feed formula of invention patent CN116391671B, and will not be repeated here. After determining the mass of each raw material, divide all raw materials into multiple equal portions according to the component ratio, and then add them to the mixing device 1 in batches.

[0038] S2. The raw materials output from S1 are sequentially fed into the mixing device 1 using the feeding device 2. The mixing time is set to 0.5 hours to obtain the composition. The amount of raw materials fed into the mixing device 1 each time is 400-500 kg. Based on the daily feed consumption of 1500 kg, it needs to be fed in 3 times. The total mixing time does not exceed 1.5 hours.

[0039] S3. The composition output in S2 is sequentially fed into the crushing device 3 by the conveying device 4, and the rotation speed of the cutter 11 is set to crush the composition into particles not exceeding 2mm.

[0040] S4. The particles output in S3 are conveyed to the forming device 6 via a slide, and the rotation speed of the pressing knife 24 is set to compact the particles into feed of a specific shape.

[0041] It should be noted that the conveying speeds of both the feeding device 2 and the conveying device 4 can be adjusted by changing the motor speed, and can be adjusted according to the actual situation.

[0042] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
