Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste treatment equipment, specifically to a mixing device with crushing and feeding functions that is easy for black soldier fly larvae to consume. Background Technology
[0002] Black soldier fly larvae have emerged as a promising insect for biowaste treatment, reducing dry mass (DM) by up to 85% and converting it into protein- and fat-rich larval biomass, valuable as feed for livestock (pigs and poultry), aquaculture, or as pets (birds and dogs). Furthermore, they produce insect sand, a nutrient-rich byproduct containing beneficial microorganisms that promote plant growth.
[0003] Currently, in the large-scale breeding of black soldier flies, it is necessary to crush lignocellulosic waste such as branches, green waste, and waste wood, and then mix them with auxiliary materials such as soybean meal and rice bran in a certain proportion to form a culture medium suitable for larvae to eat. Because coarse fiber materials such as branches and waste wood have high hardness, traditional mixing equipment can usually only achieve mixing and stirring of materials, but cannot achieve crushing and mixing of materials. Moreover, it cannot simultaneously feed multiple materials. In addition, the crushed materials are mixed with materials that have been crushed to the required particle size and cannot be separated in time. This results in poor mixing effect, reduces the material crushing and mixing efficiency, and also affects the subsequent consumption of black soldier flies. Utility Model Content
[0004] In view of this, the present invention provides a mixing device with crushing and feeding functions that is easy for black soldier fly larvae to consume. It can not only add various materials simultaneously, but also crush the materials while performing efficient mixing, which greatly improves the mixing efficiency and the mixing effect.
[0005] To address the aforementioned technical problems, this utility model provides a mixing device with crushing and feeding functions that facilitates the consumption of black soldier flies. The device includes a mixing drum, inside which a crushing and mixing component is rotatably mounted. This component includes a drive unit with a stirring shaft driven on it. Multiple crushing blades and a spiral feeding blade are located on the outer side of the stirring shaft. A feeding component, comprising a main material feeding hopper and an auxiliary material feeding hopper, is also mounted on the mixing drum. This utility model enables the simultaneous addition of materials by classifying and dividing them into zones through the feeding component. Simultaneously, the crushing and mixing component efficiently crushes and mixes the materials within the mixing drum, significantly improving mixing efficiency. This solves the problem that traditional mixing equipment typically only performs mixing and stirring, failing to crush and mix materials, and cannot simultaneously feed multiple materials. Furthermore, the crushed materials are often mixed with materials of the required particle size, resulting in poor mixing and reduced crushing and mixing efficiency, thus affecting the subsequent consumption of black soldier flies.
[0006] A fixed frame is provided at the bottom of the mixing tank, which is horizontally mounted on the fixed frame. The main material feed hopper is located at the end of the mixing tank and is inclined downwards. The lowest point of the main material feed hopper is connected to the side wall of the mixing tank. The auxiliary material feed hopper is located on the axial side wall of the mixing tank, and its lower part is connected to the axial side wall of the mixing tank. This utility model can realize the addition of the main mixed material, such as leaves, through the main feed hopper, and can realize the synchronous or intermittent addition of the mixed material, such as bran and corn flour, through the auxiliary material feed hopper. This greatly improves the feeding speed and efficiency of the mixing tank under different feeding requirements, and makes the operation more convenient.
[0007] The auxiliary material feed hopper has a funnel-shaped structure with a larger opening at the top than at the bottom. This invention can create a ramp through the design of the auxiliary material feed hopper, which is larger at the top and smaller at the bottom, so that the auxiliary materials can slide smoothly into the mixing tank. Moreover, the design of the larger top and smaller bottom can, to a certain extent, prevent the escape of crushed materials from the mixing tank during the mixing process.
[0008] The driving component is a servo motor, and its housing is mounted on the frame. A drive wheel is located at the end of the drive shaft, and a driven wheel is located on the outer side of the stirring shaft. The drive wheel and driven wheel are connected by a belt drive. This invention allows the drive wheel to rotate along with the output shaft of the servo motor. Furthermore, the rotation of the drive wheel drives the driven wheel, which in turn drives the stirring shaft, via the belt. The rotation of the stirring shaft synchronously rotates the crushing blades and spiral feeding blades on its outer side, achieving simultaneous crushing and mixing of the material in the mixing tank and conveying it along the spiral conveyor direction, making the process more convenient and efficient.
[0009] The mixing tank is also equipped with a discharge assembly, which includes a first discharge port and a second discharge port. A filter screen is installed at the connection point between the first discharge port and the mixing tank. This invention can filter the crushed material through the filter screen installed at the first discharge port. The crushed material smaller than the diameter of the filter screen will fall through the filter screen and be collected. A switch valve is installed at the second discharge port. After crushing and mixing are completed, opening the switch valve can discharge the insufficiently crushed material in the mixing tank for centralized collection and further crushing, making the operation more convenient.
[0010] The first and second discharge ports are located at the lower part of the mixing tanks on both sides of the frame, and both are connected to the side wall of the mixing tanks. This utility model can realize the graded and classified discharge and collection of materials through the first and second discharge ports, which is more convenient.
[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0012] 1. This utility model can realize the synchronous or intermittent feeding of mixed materials by classifying and dividing them by the main material feeding hopper and auxiliary material feeding hopper set on the mixing tank, which makes the operation more convenient and avoids the problem that traditional mixing devices only have one feeding port, which makes it impossible to feed multiple materials at the same time.
[0013] 2. This utility model can achieve graded, classified, and zoned discharge of crushed and mixed materials through the design of the first and second discharge ports and the filter screen set at the first discharge port, which greatly improves the efficiency of crushing and mixing materials.
[0014] 3. This utility model can achieve efficient crushing of materials entering the mixing tank while simultaneously performing mixing and conveying operations by using a stirring and crushing component that rotates inside the mixing tank, which greatly improves the efficiency of material mixing and separation.
[0015] 4. This utility model can guide and transport the material by using the spiral feeding blades set on the outside of the mixing shaft. During the crushing and mixing process, the output shaft of the drive unit rotates the spiral feeding blades in a direction that transports the material away from the discharge component, thus achieving a thorough and efficient crushing operation. After the crushing and mixing operation is completed, the output shaft of the drive unit rotates the spiral feeding blades in a direction that transports the material closer to the discharge component, thus achieving a thorough and efficient discharge operation of the material.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0021] like Figure 1-3As shown: This embodiment provides a mixing device with crushing and feeding functions that is convenient for black soldier fly larvae to consume. It includes a mixing tank 100, inside which a crushing and mixing component 200 is rotatably mounted. The crushing and mixing component 200 includes a drive member 210, on which a stirring shaft 220 is driven. Multiple crushing blades 230 are arranged on the outer side of the stirring shaft 220, and spiral feeding blades 240 are also arranged on the outer side of the stirring shaft 220. A feeding component 300 is also provided on the mixing tank 100. The feeding component 300 includes a main material feeding hopper 301 and an auxiliary material feeding hopper 302. The auxiliary material feeding hopper 302 has a funnel-shaped structure with an upper opening larger than a lower opening. This invention utilizes the design of the auxiliary material feeding hopper 302, which is wider at the top and narrower at the bottom, to create a ramp, facilitating the smooth sliding of auxiliary materials into the mixing tank 100. Furthermore, the design, which is wider at the top and narrower at the bottom, can prevent the escape of crushed materials during the mixing process. This invention can achieve the simultaneous addition of materials by classifying and dividing them into zones through the feeding component 300, and at the same time, the crushing and mixing component 200 can achieve efficient crushing and mixing of materials in the mixing tank 100, which greatly improves the mixing efficiency of materials. This solves the problem that traditional mixing equipment can usually only achieve mixing and stirring of materials, but cannot achieve crushing and mixing of materials, and cannot simultaneously feed multiple materials. In addition, the crushed materials are mixed with materials that have reached the required particle size and cannot be separated in time, which leads to poor mixing effect, reduces the crushing and mixing efficiency of materials, and also affects the subsequent consumption of black soldier fly larvae.
[0022] Another implementation of mixing tank 100 is as follows: Figure 1 As shown, the mixing tank 100 is formed by the joining of two semi-cylindrical structures. Each of the two semi-cylindrical mixing tanks 100 has an axially extending through-hole. A sealed bearing is installed within the through-hole. The stirring shaft 220 passes through the inner ring of the sealed bearing and is fixed thereto. A sealing gasket is placed between the outer ring of the sealed bearing and the through-hole of the mixing tank 100. The two semi-cylindrical mixing tanks 100 are hinged together, and after joining, they form a complete cylinder. The upper semi-cylindrical mixing tank 100 has a handle on its outer side, and it is detachably connected to the lower semi-cylindrical mixing tank 100 by bolts and nuts.
[0023] According to one embodiment of the present invention, such as Figure 1 and Figure 2As shown, a fixing frame 400 is provided at the lower part of the mixing tank 100. The mixing tank 100 is horizontally arranged on the fixing frame 400. A rubber protective pad is provided at the bottom of the fixing frame 400. The main material feed hopper 301 is located at the end of the mixing tank 100 and is inclined downward. The lowest end of the main material feed hopper 301 is connected to the side wall of the mixing tank 100. The auxiliary material feed hopper 302 is arranged on the axial side wall of the mixing tank 100, and its lower part is connected to the axial side wall of the mixing tank 100. This utility model can realize the addition of the main mixed material such as leaves through the main feed hopper, and can realize the addition of the mixed material such as bran and corn flour in sections synchronously or intermittently through the auxiliary material feed hopper 302, which greatly improves the feeding speed and efficiency of the mixing tank 100 under different feeding requirements and makes the operation more convenient.
[0024] The drive component 210 is a servo motor, and the output shaft of the servo motor can rotate in both directions. The housing of the drive component 210 is mounted on the frame. A drive wheel 211 is provided at the end of the output shaft of the drive component 210, and a driven wheel 212 is provided on the outer side of the stirring shaft 220. The drive wheel 211 and the driven wheel 212 are connected by a belt drive. This invention can rotate the drive wheel 211 together with the output shaft of the servo motor. In addition, the rotation of the drive wheel 211 can drive the driven wheel 212 to rotate together with the stirring shaft 220 via the belt. The rotation of the stirring shaft 220 can drive the crushing blade 230 and the spiral feeding blade 240 on its outer side to rotate synchronously, so as to realize the crushing and mixing of the material in the mixing tank 100 and the conveying operation along the spiral conveying direction at the same time, which is more convenient and efficient.
[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, a discharge assembly 500 is also provided on the mixing tank 100. The discharge assembly 500 includes a first discharge port 501 and a second discharge port 502. A filter screen 600 is provided at the connection point between the first discharge port 501 and the mixing tank 100. The first discharge port 501 and the second discharge port 502 are located at the lower part of the mixing tank 100 on both sides of the frame, and both are in communication with the side wall of the mixing tank 100. This utility model can realize the graded and classified discharge and collection of materials through the first discharge port 501 and the second discharge port 502, which is more convenient. This utility model can realize the filtration of crushed materials through the filter screen 600 provided on the first discharge port 501. The crushed materials smaller than the diameter of the filter screen 600 will fall through the filter screen 600 and be collected. A switch valve is provided at the second discharge port 502. When the crushing and mixing are completed, the switch valve can be opened to realize the discharge and centralized collection of the insufficiently crushed materials in the mixing tank 100 for further crushing, which is more convenient to operate.
[0026] How to use this utility model:
[0027] First, it needs to be clarified that the mixing device involved in this utility model is mainly used for crushing and mixing leaves, bran, and cornmeal. The crushed mixture is then fed to black soldier flies, achieving centralized collection of leaves and waste utilization. The reason for adding bran and cornmeal is that the leaves need to be mixed with a certain amount of bran to form feed for the insects to eat. If they only eat leaves, the leaves contain little moisture and are not moisturizing enough. Adding bran and cornmeal helps retain moisture, making the leaves more appealing to black soldier flies and facilitating feeding for other types of insects. The ammonia in the excrement of the black soldier flies after consuming the leaves will be treated and degraded by microorganisms. This utility model uses leaves as feed for black soldier flies... The following is a detailed explanation of its usage, using the mixing of auxiliary materials such as bran and corn as an example. When mixing materials is required, the leaves are first fed into the first feed hopper, and at the same time, the output shaft of the drive unit 210 is started to rotate. The rotation of the output shaft of the servo motor drives the drive wheel 211 to rotate as well. In addition, the rotation of the drive wheel 211 can drive the driven wheel 212 to rotate along with the stirring shaft 220 via a belt. The rotation of the stirring shaft 220 can synchronously rotate the crushing blade 230 and the spiral feeding blade 240 on its outer side, so as to crush and mix the materials in the mixing tank 100 while conveying them along the spiral direction. During the conveying operation, depending on the condition of the crushed mixture, appropriate timing is selected to inject auxiliary materials such as bran, corn flour, and water through the second feed hopper. During the crushing and mixing process, the output shaft of the drive unit 210, carrying the spiral feeding blades 240, rotates in a direction that conveys the material away from the discharge assembly 500, achieving thorough and efficient crushing of the material. After the crushing and mixing operation is completed, the output shaft of the drive unit 210, carrying the spiral feeding blades 240, rotates in a direction that conveys the material closer to the discharge assembly 500, achieving efficient discharge of the thoroughly mixed material. This invention can utilize the feeding group... The component 300 enables the simultaneous addition of materials by classifying and dividing them into zones. At the same time, the crushing and mixing component 200 enables the efficient crushing and mixing of materials in the mixing tank 100, which greatly improves the mixing efficiency of materials. This solves the problem that traditional mixing equipment can only perform mixing and stirring operations on materials, but cannot perform crushing and mixing operations on materials, and cannot simultaneously feed multiple materials. In addition, the crushed materials are mixed with materials that have reached the required particle size and cannot be separated in time, which leads to poor mixing effect, reduces the crushing and mixing efficiency of materials, and also affects the subsequent consumption of black soldier fly larvae.
[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
