Description

Technical Field

[0001] This utility model relates to a bidirectional feeding mechanism and its mobile feeding vehicle for black soldier fly larvae farming, belonging to the field of black soldier fly egg farming technology. Background Technology

[0002] In the black soldier fly farming industry, the application of automated three-dimensional farming technology is relatively limited and its adoption rate is not high. Furthermore, the facilities and equipment required for automated three-dimensional farming not only have high investment costs but also incur significant maintenance and repair expenses during operation. In contrast, the mainstream farming method currently on the market remains the traditional flat-bed pond farming technology. Flat-bed pond farming requires a large area of ​​land, and the farming methods are relatively extensive, relying heavily on manual labor for key tasks such as spreading feed and collecting insects. This manual labor-intensive method generates high labor costs, thus limiting the realization of large-scale farming. Summary of the Invention

[0003] The purpose of this invention is to provide a bidirectional feeding mechanism and its mobile feeding vehicle for black soldier fly larvae planar aquaculture, which can automatically transport and precisely deliver kitchen waste during pond aquaculture, as well as clean and transport materials such as insect excrement within the site, thereby reducing costs, improving overall production efficiency, and facilitating the expansion of production scale.

[0004] The technical solution of this utility model to achieve the above objectives is: a bidirectional feeding mechanism for black soldier fly planar aquaculture, characterized in that: it includes a bucket and a material conveying and feeding mechanism; The bucket has a discharge port in the lower middle part of both side plates, two adjustable baffles for the height of the discharge port are installed on the corresponding side plates, and the bucket has an extended material distribution plate on the outside of the discharge port. The material conveying and actuating mechanism is installed on the bucket. The material conveying and actuating mechanism includes a motor, a drive roller, a driven roller, a conveyor belt, and scrapers. The drive roller and driven roller, which are located inside the bucket, are rotatably mounted on the bucket's bearing. The motor is installed outside the bucket and connected to the drive roller. The conveyor belt is installed on the drive roller and driven roller and is used to discharge material to both sides. The drive roller has drive sprockets at both ends, and the driven roller has driven sprockets at both ends. Two chains are installed on the corresponding drive sprockets and drive rollers, and multiple scrapers are installed on the two chains.

[0005] Another technical solution of this utility model to achieve the above-mentioned objective is: a mobile feeding vehicle for black soldier fly larvae planar aquaculture, characterized in that it includes a mobile vehicle, a fixed frame, a lifting mechanism, a bucket tilting mechanism, and a bidirectional feeding mechanism. The mobile vehicle has a front support at the front, and lower support arms are installed on both sides of the lower part of the front support and the lower parts of the fixed frame. Swing cylinders are hinged to both sides of the middle part of the front support and the middle parts of the fixed frame. The lifting mechanism is mounted on the fixed frame and includes a lifting frame, lifting cylinders, sprockets, and a lifting chain. Lifting cylinders are installed on both sides of the fixed frame, and the piston rods of the lifting cylinders have support seats at their ends. The sprockets pass through… The bearing is mounted on the support seat. One end of the lifting chain mounted on the sprocket is fixed to the upper part of the fixed frame, and the other end is fixed to the lower middle part of the lifting frame. The guide roller mounted on the inner side of the fixed frame is connected to the lifting frame. The bucket tilting mechanism is connected to the lifting frame. The bucket tilting mechanism includes a bucket seat, a tilting cylinder and a tilting arm. The bucket seat is provided with a tilting support. The bucket seat is connected to the lifting frame. The front ends of the two side plates of the bucket seat are hinged to the bucket body hinge seat. The fixed end of the tilting cylinder is mounted on the rear end plate of the bucket seat, and the telescopic end is hinged to the rear end of the tilting arm. The front end of the tilting arm is hinged to the tilting seat on the bucket. The lower middle part of the tilting arm is hinged to the tilting support.

[0006] This utility model's bidirectional feeding device employs a bucket and a material feeding mechanism installed inside the bucket. The active and passive rollers of the material feeding mechanism are rotatably mounted on the bucket's shaft seat. Therefore, the conveyor belt inside the bucket, driven by a motor, can rotate the material added to the bucket in both directions, delivering the material to the discharge ports on both sides. The material is then scraped out by scrapers. Since the size of the discharge ports on both sides is adjustable, the feeding amount and feeding distance can be controlled by adjusting the conveyor speed in the bucket, the size of the discharge ports, and the bucket height, while achieving bidirectional feeding. This allows for precise feeding, determining the feeding amount for each pond, facilitating production calculations and management, and improving the efficiency and scale of black soldier fly larvae farming. This invention utilizes a mobile feeding cart to discharge kitchen waste from the storage tank into the front bucket. The cart can then travel to the aisle of the aquaculture ponds, where the motor is started and its forward and reverse rotation controlled. The kitchen waste is then fed into the ponds through the left and right outlets. This mobile cart can move flexibly back and forth within the aquaculture area, evenly distributing the kitchen waste throughout the ponds. This automates the handling and precise distribution of kitchen waste during pond aquaculture, reducing costs and improving overall production efficiency. It can save 2-3 workers and increase production efficiency by 40%-50% during the feeding process. This mobile feeding cart not only enables bidirectional feeding during the aquaculture process but also allows for the cleaning and transportation of insect excrement, black soldier fly larvae, and other materials after the aquaculture is completed, achieving multi-purpose functionality. This is of great significance for expanding production scale and achieving standardized and streamlined production, empowering modern agriculture in the new era. Attached Figure Description

Specific Implementation

[0015] See Figures 1-4 As shown, this utility model discloses a bidirectional feeding mechanism for black soldier fly larvae planar aquaculture, comprising a bucket 3 and a material conveying and feeding mechanism 5.

[0016] See Figures 1-4As shown, the bucket 3 of this utility model has a discharge port 3-21 in the lower middle part of the two side plates 3-2. Two adjustable baffles 4 with adjustable height of the discharge port 3-21 are installed on the corresponding side plates 3-2. The bucket 3 has an outwardly extending distribution plate 3-1 on the outside of the discharge port 3-21. Therefore, by adjusting the height of the baffle 4, the size of the discharge port can be precisely controlled to control the discharge volume. The kitchen waste is discharged into the breeding pond through the distribution plate 3-1 to achieve precise distribution.

[0017] See Figures 1-4 As shown, the material conveying mechanism 5 of this utility model is installed on the bucket 3. The material conveying mechanism 5 includes a motor 5-1, a drive roller 5-6, a driven roller 5-7, a conveyor belt 5-4, and a scraper 5-3. The drive roller 5-6 and the driven roller 5-7, which are located inside the bucket 3, are rotatably mounted on the bearing seats of the bucket 3. Bearing seats can be provided on both sides of the bucket 3, and the drive roller 5-6 and the driven roller 5-7 are mounted on the bearing seats through bearings. The motor 5-1 is installed outside the bucket 3 and connected to the drive roller 5-6. The conveyor belt 5-4 is installed on the drive roller 5-6 and the driven roller 5-7 and is used to discharge materials to both sides. Therefore, the motor 5-1 drives the drive roller 5-6 to rotate forward and backward, thereby driving the conveyor belt 5-4 to feed materials in both directions. See Figure 4 As shown, the active roller 5-6 of this utility model has active sprockets 5-5 at both ends, and passive roller 5-7 has passive sprockets 5-8 at both ends. Two chains 5-2 are installed on the corresponding active sprockets 5-5 and active sprockets 5-8. Multiple scraper plates 5-3 are installed on the two chains 5-2. The scraper plates 5-3 push the material out of the discharge ports 3-21 on both sides. When the motor 5-1 drives the active roller 5-6 to rotate forward and backward, the scraper plates 5-3 simultaneously move forward and backward to push the material through the discharge ports 3-21 to the material distribution plate 3-1, thus realizing bidirectional material distribution. The feeding amount and feeding distance can also be controlled by adjusting the speed of the conveyor belt 5-4 in the bucket 3 and the height of the bucket 3.

[0018] See Figures 1-3 As shown, the bottom of the bucket 3 of this utility model is arc-shaped. The bucket 3 has a mounting hole on the upper part of the side plate 3-2. The mounting hole of the side plate 3-2 is located above the discharge port 3-21. The bottom of the adjusting baffle 4 has an arc-shaped edge that matches the arc surface of the bottom of the bucket 3. The adjusting baffle 4 has an adjusting groove 4-1 along the height direction. The adjusting groove 4-1 has multiple adjusting holes. The bolt 6 passes through the mounting hole of the side plate 3-2 and the adjusting hole on the adjusting groove 4-1 of the adjusting baffle 4 and is fixed with a nut 7. Therefore, it is convenient to adjust the height position of the baffle 4 and control the size of the discharge port 3-21. The amount of feed can be adjusted according to the breeding requirements. When the adjusting baffle 4 is lowered to the bottom, the discharge port 3-21 is closed. After the breeding is completed, the insect excrement, black soldier fly larvae and other materials are cleaned and transported.

[0019] See Figure 1As shown, the adjusting groove 4-1 on the adjusting baffle 4 of this utility model includes a straight groove and a plurality of U-shaped adjusting holes located on one side of the straight groove and communicating with each other. The bolt 6 can move within the straight groove and the adjusting holes. Therefore, when adjusting the height of the adjusting baffle 4, it is only necessary to loosen the nut 7, move the bolt 6 and the nut 7 together to the adjusting hole of the required height, and then tighten the nut 7 to fix the adjusting baffle 4 on the side plate 3-2. The adjustment operation is convenient and quick.

[0020] See Figures 1-3 As shown, the bucket 3 of this utility model has inclined inner baffles 3-3 on the front and rear sides of the conveyor belt 5-4. The bottom of the two inner baffles 3-3 is located outside the discharge port 3-21. When the kitchen waste in the storage tank is discharged into the bucket through the discharge port of the spiral tail, it is placed on the conveyor belt 5-4 located between the two inner baffles 3-3. This utility model has at least two support columns in the bucket 3. The protective cover covering both sides of the conveyor belt 5-4 can be detachably installed on the support columns to reduce the amount of material entering the interior of the conveyor belt 5-4. When the moving vehicle 18 travels to the passage of the breeding pond, the bucket 3 evenly distributes the kitchen waste into the two breeding ponds to achieve bidirectional material distribution. At the same time, when cleaning insect excrement, black soldier fly larvae and other materials, the inner baffles 3-3 can also reduce the amount of cleaned material from entering the conveyor belt 5-4, realizing multiple uses of one machine.

[0021] See Figure 3 As shown, the bucket 3 of this utility model has bucket body hinge seats 3-4 on both sides of its back and a flipping seat 3-5 in the middle. It is connected to the bucket seat 1 through the hinge seats and the flipping seat 3-5. The flipping angle of the bucket 3 is controlled by the extension and retraction of the flipping cylinder 2, thereby realizing the loading of kitchen waste and the cleaning and transportation of insect excrement, black soldier flies and other materials after the breeding is completed.

[0022] See Figure 5 , 6 As shown, the present invention relates to a mobile feeding vehicle for black soldier fly larvae planar aquaculture, comprising a mobile vehicle 18, a fixed frame 10, a lifting mechanism, a bucket tilting mechanism, and a bidirectional feeding mechanism.

The front of the mobile vehicle 18 is provided with a front support 18-1. Lower support arms 17 are installed on both sides of the lower part of the front support 18-1 and the lower sides of the fixed frame 10. Swing cylinders 16 are hinged to both sides of the middle part of the front support 18-1 and the middle sides of the fixed frame 10. The fixed frame 10 is connected through the two lower support arms 17 and the two swing cylinders 16, and the forward and backward tilting angles of the fixed frame 10 are adjusted by the extension and retraction of the swing cylinders 16.

[0023] See Figure 5 , 6As shown, the lifting mechanism of this utility model is installed on a fixed frame 10. The lifting mechanism includes a lifting frame 11, a lifting cylinder 12, a sprocket 13, and a lifting chain 14. The fixed frame 10 has lifting cylinders 12 installed on both sides. The piston rod of the lifting cylinder 12 is provided with a support seat 15 at its end. The sprocket 13 is installed on the support seat 15 through a bearing. One end of the lifting chain 14 installed on the sprocket 13 is fixed to the upper part of the fixed frame 10, and the other end is fixed to the lower middle part of the lifting frame 11. By controlling the extension and retraction of the lifting cylinder 12, the lifting chain 14 is driven, which in turn controls the lifting frame 11 to drive the bucket 3 to achieve height changes to meet various operations. The guide roller 9 installed on the inner side of the fixed frame 10 is connected to the lifting frame 11, so the lifting frame 11 can be raised and lowered smoothly through the guide roller 9.

[0024] See Figure 5 , 6 As shown, the bucket tilting mechanism of this utility model is connected to the lifting frame 11, and the lifting frame 11 drives the bucket tilting mechanism to move up and down. See Figure 3 , 5 As shown, the bucket tilting mechanism of this utility model includes a bucket base 1, a tilting cylinder 2, and a tilting arm 8. The bucket base 1 is equipped with a tilting support 1-2. The bucket base 1 is connected to the lifting frame 11. The front ends of the two side plates of the bucket base 1 are hinged to the bucket body hinge seats 3-4. The fixed end of the tilting cylinder 2 is mounted on the rear end plate of the bucket base 1, and the telescopic end is hinged to the rear end of the tilting arm 8. The front end of the tilting arm 8 is hinged to the tilting seat 3-5 of the bucket 3. The lower middle part of the tilting arm 8 is hinged to the tilting support 1-2. The tilting cylinder 2 can control the tilting angle of the bucket 3 to meet the requirements of the vehicle in material placement, cleaning, and transportation. See Figure 3 , 5 As shown, the bucket seat 1 of this utility model includes an integral rear end plate and two side seat plates. The top surface of the side seat plates slopes downward from back to front. A reinforcing beam 1-1 is fixed between the two side seat plates. A tilting support 1-2 is provided in the middle of the reinforcing beam 1-1. Therefore, the front end, rear end and lower middle part of the tilting arm 8 are respectively hinged to the bucket body hinge seat 3-4 of the bucket 3, the telescopic rod of the tilting cylinder 2 and the tilting support 1-2.

[0025] See Figure 5 , 6As shown, the fixed frame 10 of this utility model includes two frame columns 10-2, two horizontal rectangular frames 10-1 at the top, and a bottom crossbeam. The bottom crossbeam is fixed to the bottom of the two frame columns 10-2, and the two horizontal rectangular frames 10-1 are fixed to the upper part of the outer side of the two frame columns 10-2. Therefore, the fixed frame 10 has good strength. The lifting frame 11 includes two lifting columns 11-2 and a fixing plate 11-1 fixed on the two lifting columns 11-2. The fixing plate 11-1 is connected to the bucket seat 1 by fasteners. Similarly, while ensuring the strength of the lifting frame 11, it is convenient to replace different tools. The horizontal rectangular frames 10-1 at the top of the fixed frame 10 and the lifting frame 11 are respectively provided with chain seats. The two ends of the lifting chain 14 are respectively installed on the corresponding chain seats, which facilitates the installation of the lifting chain 14.

[0026] See Figure 5 , 6 As shown, the frame column 10-2 of this utility model is a column with an inner guide groove on the inner side. At least two fixing sleeves are fixed along the height direction of the frame column 10-2. The number of fixing sleeves can be set according to the lifting height. The lifting column 11-2 is a column with an outer guide groove on the outer side. The support shaft on the guide roller 9 is installed in the fixing sleeve. The guide roller 9 is set in the inner guide groove of the frame column 10-2 and the outer guide groove of the lifting column 11-2. During the lifting process of the lifting frame 11, the running resistance is reduced by the guide roller 9.

[0027] See Figures 1-6 As shown, when the mobile feeding vehicle for black soldier fly larvae farming of this utility model is in operation, the tilt angle of the bucket 3 is adjusted by the swing cylinder 16 and the tilting cylinder 2. The adjusting baffle 4 is moved down to close the discharge ports 3-21 on the left and right sides. The mobile vehicle 18 is driven to the storage tank, and the lifting cylinder 12 is activated. The sprocket 13 on the piston rod of the lifting cylinder 12 moves upward, and the lifting chain 14 lifts the lifting frame 11 to the bucket 3 to a suitable height. The kitchen waste from the storage tank is discharged into the bucket through the auger tail discharge port. In step 3, drive the mobile vehicle 18 to the aisle of the breeding pond, adjust the height of the adjusting baffle 4 and control the size of the discharge port 3-21, start the motor 5-1 and control the speed of the conveyor belt 5-4 to rotate forward and backward. The kitchen waste is fed into the breeding ponds on both sides through the discharge ports on the left and right sides. After the feeding is completed, turn off the motor 5-1, adjust the adjusting baffle 4 to move down and close the discharge port 3-21, drive the mobile vehicle to the designated position, start the tilting cylinder 2 and lifting cylinder 12 to lower the bucket 3 and place it on the ground. After the breeding is finished, drive the mobile vehicle to the breeding pond, start the tilting cylinder 2 and lifting cylinder 12 to adjust the bucket 3 to the shoveling position, scrape and clean the materials such as insect excrement in the site, then start the tilting cylinder 2 and lifting cylinder 1 to adjust to the bucket transport position, and drive the mobile vehicle 18 to the unloading position.
