Description

Technical Field

[0001] The utility model relates to an automatic insect throwing device for breeding black soldier fly larvae, belonging to the field of insect breeding equipment. Background Art

[0002] In the three-dimensional breeding of black soldier flies, throwing insects is an important link. Generally speaking, there are two ways of feeding: multiple feeding and one-time large-scale feeding. Multiple feeding can better control the consumption of food. However, the gap between the existing three-dimensional breeding platforms for black soldier flies is very small, generally not more than 10cm. Such a gap is difficult to achieve automated operation, resulting in the need to move the breeding box out of the frame each time the insects are thrown, and then move it back into the frame after throwing the insects. The operation is complicated and the labor cost is high. In addition, some factories increase the gap between the three-dimensional breeding platforms for black soldier flies, which results in a higher overall single-layer equipment, which is not conducive to intensive production. One-time throwing of insects is to mix the black soldier fly larvae with the food. There are the following problems: the black soldier fly larvae are easily pressed in the food. Since the initial insect body is small, a large number of larvae mixed in the food die, which is not conducive to subsequent production. Utility Model Content

[0003] The utility model provides an automatic feeding device for breeding black soldier fly larvae, which solves the problem that the larvae are mixed in food and easily die in the existing single feeding process.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] like Figure 1 As shown, an automatic insect throwing device for breeding black soldier fly larvae includes an insect box 3, a lower feed bin 2, a fixed frame 1 and an automatic insect throwing mechanism.

[0022] The insect box 3 is mainly used to store larvae. In this embodiment, a square structure with upper and lower openings is adopted. According to actual conditions, a structure with a cover plate and / or a heat preservation device can also be selected. The inside of the insect box 3 is divided into a plurality of quantitative bins 5 by a partition plate 4. In this embodiment, it is divided into four parts. According to actual conditions, it is also possible to choose not to set the partition plate 4 or change the number of the partition plates 4.

[0023] The lower feed bin 2 adopts a conical structure, and the insect box 3 and the lower feed bin 2 are installed together by bolts.

[0024] The fixed frame 1 is mainly used to facilitate the installation and fixation of the equipment. In this embodiment, it is composed of four square steel pipes, and other structures can also be used as long as they are convenient for fixation. The fixed frame 1 is installed together with the lower silo 2; it can also be installed together with the insect box 3.

[0025] The main purpose of the automatic insect throwing mechanism is to realize the release of black soldier fly larvae at a specific time according to demand. In this embodiment, the automatic insect throwing mechanism includes a base plate 12 and a power mechanism arranged at the bottom of each quantitative bin 5. A reinforcing plate 10 is arranged under the base plate 12. The end of the reinforcing plate 10 extending out of the lower bin 2 is provided with a long strip hole 9. The reinforcing plate 10 is installed together with the rotating frame 11 through a rotating pin 8. The rotating frame 11 is fixed together with the lower bin 2 through bolts. The lifting pin 7 passes through the long strip hole 9 to install the reinforcing plate 10 and the power mechanism together. The other end of the power mechanism is fixed to the outer wall of the insect box 3.

[0026] The main purpose of the power mechanism is to push the bottom plate 12 up and down to open or close the quantitative bin 5. An electric push rod, a hydraulic cylinder or a gas cylinder can be used. In this embodiment, an electric push rod 6 is used. The electric push rod 6 is connected to a controller. The controller is a commonly used PLC controller in the art, which is not marked in the figure.

[0027] The black soldier fly larvae released by the utility model are living animals. During release, the bottom of the lower hopper 2 is at a certain height from the material layer, and there is a risk that the black soldier fly larvae will splash and escape at the moment of release. Therefore, a flexible enclosure 13 is provided at the bottom of the lower hopper 2, and the flexible enclosure 13 is in contact with the material layer, which can effectively prevent the black soldier fly larvae from splashing and escaping.

[0028] The operation process of this embodiment:

[0029] According to the length of the cloth layer, the number of feedings is set, and the black soldier fly larvae are evenly placed in each quantitative bin 5. During the process of feeding, the controller controls the electric push rod to contract according to the set insect throwing time, thereby driving the lifting pin to move from the top to the outer end in the rectangular hole, thereby driving the reinforcing plate and the bottom plate to rotate along the rotating shaft, and the bottom plate 12 is opened. The black soldier fly larvae are quickly dropped from each quantitative bin 5 onto the material layer. After the dropping is completed, the electric push rod moves in the opposite direction, closes the bottom plate, and completes the insect throwing operation. In this embodiment, there are four quantitative bins 5, and the operation of throwing insects four times in one material layer can be realized.

[0030] The insect throwing device of this embodiment has a compact and simple structure and can throw black soldier fly larvae onto the surface of the material layer, effectively solving the problem of large-scale death of black soldier fly larvae when the larvae are mixed with food and laid on the material.

[0031] Example 2

[0032] The insect throwing method of Example 1 is intermittent throwing, which has the problem of uneven distribution of thrown insects. This embodiment adopts the method of continuous throwing, opens a certain gap in the bottom plate 12, and allows the black soldier fly larvae to slowly fall onto the material layer, so that one quantitative bin 5 can complete the throwing of larvae in one layer of material layer. However, black soldier fly larvae are prone to agglomeration during the throwing process, and there is a problem of climbing upwards when they are active, resulting in uneven larvae distribution in the quantitative bin 5. In order to solve the above technical problems, this embodiment adopts the following solution:

[0033] like Figure 3 As shown, it is basically the same as embodiment 1, except that a vibration mechanism 14 is provided on the lower feed bin 2, generally a micro vibration pump is used. The vibration mechanism 14 is provided to facilitate the thorough and rapid delivery of the larvae in the quantitative bin 5.

[0034] Example 3

[0035] like Figure 4 As shown, an automatic feeding and throwing device for breeding black soldier fly larvae includes a feeding mechanism 15 and an automatic throwing device, wherein the automatic throwing device is arranged above the discharging part of the feeding mechanism. The feeding mechanism 15 adopts the structure of CN218126425U, as shown in FIG4, and the specific structure is not described in detail.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
