Abstract
Description
Technical Field
[0001] This utility model relates to the field of black soldier fly farming technology, and in particular to a black soldier fly farming rack. Background Technology
[0002] Black soldier fly larvae rearing racks are specially designed for raising black soldier fly larvae. Through rational structural design and spatial layout, they improve the efficiency and yield of black soldier fly farming. Black soldier fly larvae feed on livestock manure and household waste, producing high-value animal protein feed; therefore, black soldier fly larvae rearing racks play an important role in the resource utilization of organic waste. Multi-layered rearing racks effectively increase the rearing area by utilizing vertical space, thereby increasing the number of larvae per unit area. This is a significant advantage for farmers with limited land resources or those seeking to improve rearing efficiency, and is therefore frequently used in black soldier fly farming. However, traditional rearing racks typically use a fixed multi-layered structure, with fixed spaces between each layer, making flexible adjustments impossible according to rearing needs. This leads to inconvenience for farmers in tasks such as feeding, observation, and collection. Utility Model Content
[0003] In view of the above-mentioned prior art, the present invention provides a black soldier fly breeding rack to facilitate the feeding, observation and collection tasks of breeders.
[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:
[0005] A black soldier fly larvae breeding rack includes a column, breeding layers, pull ropes, a first reel, and a drive mechanism. Multiple breeding layers are slidably connected to the column. A first sleeve and a second sleeve are provided between the breeding layers, and the first and second sleeves are slidably sleeved together. The first sleeve is connected to the breeding layer above it, and the second sleeve is connected to the breeding layer below it. A one-way valve is provided in either the first or second sleeve. Each breeding layer has a through hole through which the pull rope passes. The upper end of the pull rope is connected to the first reel. The drive mechanism is used to drive the first reel to rotate. Each breeding layer has a clamping block for clamping the pull rope.
[0006] Furthermore, rectangular frames are provided above and below the column.
[0007] Furthermore, a retractor is provided below the pull rope, the retractor including a second reel and a torsion spring, the torsion spring being used to drive the second reel to rotate.
[0008] Furthermore, the pull rope is provided with a number of equidistant limiting blocks.
[0009] Furthermore, the clamping block is rotatably connected to the aquaculture layer, and the clamping block is provided with a slot for engaging the limiting block.
[0010] Furthermore, the drive mechanism includes a motor, a transmission shaft, a worm gear, and a worm. The motor is connected to the transmission shaft, the transmission shaft is equipped with the worm, the worm meshes with the worm gear, and the worm gear is connected to the first reel.
[0011] Furthermore, diagonal braces are provided between the columns.
[0012] Furthermore, the motor is connected to multiple control switches, which are push-button switches connected in parallel and located on the aquaculture layer.
[0013] The beneficial effects of this invention are as follows: By sliding multiple breeding layers onto the column, vertical space can be efficiently utilized for black soldier fly farming, increasing the breeding capacity per unit area. Using a drive mechanism and rope system, the height of the breeding layers can be easily adjusted, allowing operators to move the uppermost layer upwards independently when feeding, observing, or collecting, thus freeing up more operating space and improving work efficiency. A one-way valve is installed between the first and second sleeves. If the breeding layer accidentally falls after rising, the closure of the one-way valve and the slow outflow of gas from the gaps will cause the layer to descend slowly, effectively preventing safety issues such as pinching injuries that could occur from a rapid fall.

[0020] Example 1
[0021] Please refer to the attached document. Figure 1 This application provides a black soldier fly larvae breeding rack, including a column 1, breeding layers 2, pull ropes 3, a first reel 4, and a drive mechanism 5. The column 1 is slidably connected to multiple breeding layers 2. A first sleeve 6 and a second sleeve 7 are provided between the breeding layers 2. The first sleeve 6 and the second sleeve 7 are slidably sleeved together. The first sleeve 6 is connected to the breeding layer 2 above it, and the second sleeve 7 is connected to the breeding layer 2 below it. The first sleeve 6 or the second sleeve 7 is provided with a one-way valve 8. The breeding layer 2 is provided with a through hole 9 through which the pull rope 3 passes. The upper end of the pull rope 3 is connected to the first reel 4. The drive mechanism 5 is used to drive the first reel 4 to rotate. The breeding layer 2 is provided with a clamping block 10 for clamping the pull rope 3.
[0022] The column 1 is stably fixed to the ground, and multiple breeding layers 2 are slidably connected to the column 1. Preferably, the breeding layer 2 has through holes 9 passing through the column 1, allowing the breeding layer 2 to slide up and down along the column 1. The breeding layer 2 is used to place black soldier flies, which are then cultivated in the breeding layer 2. A first sleeve 6 and a second sleeve 7 are provided between the breeding layers 2. The first sleeve 6 and the second sleeve 7 are slidably fitted together, and there is a certain degree of sealing between the first sleeve 6 and the second sleeve 7, making it difficult for gas to pass through the gap between the first sleeve 6 and the second sleeve 7. When the first sleeve 6 and the second sleeve 7 are far apart, gas can quickly enter the inner cavity of the first and second sleeves 7 through the one-way valve 8. However, when the first sleeve 6 and the second sleeve 7 are close together, the one-way valve 8 closes, and the gas can only slowly flow out from the gap between the first sleeve 6 and the second sleeve 7.
[0023] When the farmers need to perform tasks such as feeding, observation, and collection, the drive mechanism 5 drives the first reel 4 to rotate, gradually winding the pull rope 3 onto the first reel 4. Before or during the upward movement of the pull rope 3, the clamping block 10 on the breeding layer 2 clamps the pull rope 3 onto the breeding layer 2, causing the breeding layer 2 to move upward along with the pull rope 3. The upward movement of the breeding layer 2, through the first sleeve 6 and the second sleeve 7, pushes the other breeding layers 2 above it upward as well, providing a greater observation and operational space for the breeding layers below, facilitating feeding, observation, and collection tasks for the farmers.
[0024] After the aquaculture personnel complete tasks such as feeding, observation, and collection, the first reel 4 is reversed by the drive mechanism 5, gradually lowering and resetting the aquaculture layer 2. If the aquaculture layer 2 accidentally falls after rising, the first sleeve 6 and the second sleeve 7 will approach each other during the fall, and the gas can only slowly flow out from the gap between the first sleeve 6 and the second sleeve 7. Therefore, the aquaculture layer 2 can only move downwards slowly to prevent injury.
[0025] This invention can effectively utilize space for black soldier fly farming. At the same time, when performing tasks such as feeding, observation, and collection, the other farming layers 2 above can be moved upwards separately, thereby increasing the space above the farming layer 2 that needs to be operated, making it convenient for farmers to perform tasks such as feeding, observation, and collection.
[0026] Specifically, rectangular frames 11 are provided above and below the column 1 to connect the column 1, preventing deformation of the upper or lower end of the column 1 and improving the stability of the column 1.
[0027] Specifically, a retractor 12 is provided below the pull rope 3. The retractor 12 includes a second reel 13 and a torsion spring 14. The torsion spring 14 is used to drive the second reel 13 to rotate. After the pull rope 3 is released from the first reel 4, the torsion spring 14 drives the second reel 13 to rotate and retract the pull rope 3, thus preventing the pull rope 3 below from getting tangled.
[0028] Specifically, the pull rope 3 is provided with several equidistant limiting blocks 15. The limiting blocks 15 increase the friction of the pull rope 3, making it easier for the clamping block 10 to clamp the pull rope 3 and prevent the pull rope 3 from slipping when moving the breeding layer 2.
[0029] Specifically, the drive mechanism 5 includes a motor 17, a drive shaft 18, a worm gear 19, and a worm 20. The motor 17 is connected to the drive shaft 18, and the drive shaft 18 is equipped with the worm 20. The worm 20 meshes with the worm gear 19, and the worm gear 19 is connected to the first reel 4. When the motor 17 rotates forward, it drives the drive shaft 18 and the worm 20 to rotate forward, thereby driving the worm gear 19 and the first reel 4 to rotate forward, winding up the pull rope 3. When the motor 17 rotates in reverse, it drives the drive shaft 18 and the worm 20 to rotate in reverse, thereby driving the worm gear 19 and the first reel 4 to rotate in reverse, releasing the pull rope 3. When the motor 17 stops rotating, the worm gear 19 cannot drive the worm 20 to rotate, preventing the breeding rack from falling and causing injury.
[0030] Example 2
[0031] Please refer to the attached document. Figure 1 The difference between this embodiment and Embodiment 1 is that the clamping block 10 is rotatably connected to the aquaculture layer 2, and the clamping block 10 is provided with a slot 16 for engaging the limiting block 15. When it is necessary to clamp the pull rope 3, the clamping block 10 is rotated so that its lower end faces the pull rope 3, and the limiting block 15 on the pull rope 3 engages in the slot 16, thereby driving the aquaculture layer 2 to move when the pull rope 3 rises or falls.
[0032] Specifically, diagonal braces 21 are provided between the columns 1. The diagonal braces 21 improve the stability of the columns 1.
[0033] Specifically, the motor 17 is connected to multiple control switches 22, which are push-button switches connected in parallel and located on the breeding layer 2. When the breeding rack needs to be raised or lowered, it can be easily raised or lowered by operating the control switches 22.
[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
