[0002] The larvae of black soldier flies are scavengers with a wide range of food sources. They can feed on rotten plants, kitchen waste, animal carcasses, and feces, and are an important part of nature. By using the larvae of black soldier flies to process food waste and livestock and poultry feces, we can eventually obtain adult insects with high-quality insect protein and nutrient-rich organic insect fertilizer. At present, food waste and livestock and poultry feces are generally made into feed first, and then the feed and black soldier fly larvae are matched and added to the breeding box, and then the breeding box is placed in the breeding rack for breeding. After the breeding is completed, the breeding box is taken out to screen and collect the adult insects and residual organic matter.

[0066] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0067] The following describes the upper and lower rack equipment for breeding boxes of the present invention with reference to the accompanying drawings.

[0068] like Figures 1 to 3 As shown, the utility model provides a device for loading and unloading a breeding box, wherein the device for loading and unloading a breeding box comprises:

[0069] Fixed frame 210;

[0070] The lifting frame mechanism 220 is escalably disposed on the fixing frame 210 and has a supporting surface;

[0071] The up-and-down loading mechanism 240 includes a push-pull frame 241, a push-pull driving member 242 and a push-pull head assembly 243. The push-pull frame 241 is arranged on the lifting frame mechanism 220 and is located above the supporting surface. A push-pull groove 244 is opened on the push-pull frame 241. The connecting end of the push-pull driving member 242 is hinged on the push-pull frame 241. The telescopic end of the push-pull driving member 242 is arranged toward the breeding frame and is connected to the push-pull head assembly 243 through a guide pin shaft 245 movably penetrated in the push-pull groove 244. The push-pull head assembly 243 has a force-applying surface acting on the side plate of the breeding box, and the force-applying surface can be deflected forward and backward.

[0072] When the above-mentioned raising box loading and unloading equipment is used, since it includes a fixed frame 210, a lifting frame mechanism 220 and an upper and lower downloading mechanism 240, when it is necessary to remove the raising box on the raising frame, the lifting frame mechanism 220 can be controlled to perform lifting movement on the fixed frame 210, so that the supporting surface of the lifting frame mechanism 220 is docked with the plane of each layer of the swing box of the raising frame, and when the telescopic end of the push-pull driving member 242 of the upper and lower downloading mechanism 240 extends to the push-pull head assembly 243 and extends into the raising box, the push-pull driving member 242 is controlled to drive the push-pull head assembly 243 to retract, and when the push-pull head assembly 243 retracts, the inner side of the raising box can be hooked to pull the raising box to the supporting surface of the lifting frame mechanism 220 On the loading surface, finally control the lifting frame mechanism 220 to lift to a height that is convenient for access; or when it is necessary to put the breeding box on the supporting surface on the shelf, the lifting frame mechanism 220 can be controlled to perform lifting and lowering movements first, so that the supporting surface of the lifting frame mechanism 220 is docked with the planes of the swing boxes of each layer of the breeding rack, and when the telescopic end of the push-pull driving member 242 of the upper and lower downloading mechanism 240 is retracted to the case where the push-pull head assembly 243 is located outside the breeding box, the push-pull driving member 242 is controlled to drive the push-pull head assembly 243 to extend, and when the push-pull head assembly 243 is extended, the breeding box can be pushed to transfer to the swing box plane, thereby realizing the automatic unloading or automatic loading of the breeding box, so as to achieve the purpose of improving the efficiency of unloading and loading and reducing the labor intensity. In addition, the force application surface of the push-pull head assembly 243 can be set to be deflected forward and backward, which can facilitate the force application surface to avoid the side plate of the breeding box and extend into the breeding box. It should be particularly noted that the front and rear directions in the utility model are defined based on the push-pull direction of the breeding box by the upper and lower downloading mechanism 240.

[0073] Specifically, the fixing frame 210 needs to be arranged close to the breeding rack so that the supporting surface on the lifting frame mechanism 220 can be horizontally docked with the plane of the swing boxes of each layer of the breeding rack.

[0074] In the embodiment of the utility model, the number of the upper and lower downloading mechanisms 240 can be two, and the two upper and lower downloading mechanisms 240 are arranged in parallel on the lifting frame mechanism 220, and the force-applying surfaces of the push-pull head components 243 of the two upper and lower downloading mechanisms 240 are arranged in reverse order. That is, when the force-applying surface of the push-pull head component 243 of the upper and lower downloading mechanism 240 is arranged forward (arranged facing the connection end), the push-pull head component 243 of this upper and lower downloading mechanism 240 can act on the breeding box on the breeding rack and pull it to the supporting surface of the lifting frame mechanism 220; when the force-applying surface of the push-pull head component 243 of the upper and lower downloading mechanism 240 is arranged backward (arranged facing away from the connection end), the push-pull head component 243 of this upper and lower downloading mechanism 240 can act on the breeding box on the supporting surface and push it to the breeding rack, so that the upper and lower rack equipment can realize the automatic unloading and automatic loading of the breeding box at the same time.

[0075] Furthermore, when it is necessary to remove the breeding box from the breeding rack, the lifting frame mechanism 220 can be controlled to perform lifting movement on the fixed frame 210, so that the supporting surface of the lifting frame mechanism 220 is connected with the plane of the swing boxes on each layer of the breeding rack, and then the push-pull driving member 242 of the upper and lower downloading mechanism 240 for pulling is controlled to extend, and the extension is stopped when the force-applying surface of the push-pull head assembly 243 avoids the side plate of the breeding box and extends into the breeding box, and then the push-pull driving member 242 is controlled to retract, and the push-pull head assembly 243 can hook the side plate of the breeding box on the inside while the push-pull driving member 242 retracts. The breeding box is then pulled and transferred to the supporting surface, and finally the lifting frame mechanism 220 is controlled to be lifted to a height that is convenient for access; when the breeding box on the supporting surface needs to be put on the shelf, since the push-pull driving member 242 of the upper and lower downloading mechanism 240 is usually kept in a retracted state, and the force-applying surface of the push-pull head assembly 243 of the upper and lower downloading mechanism 240 used for pushing in the retracted state is located on the outside of the breeding box, the push-pull driving member 242 can be directly controlled to extend, and when the push-pull driving member 242 is extended, the push-pull head assembly 243 can hook the outside of the breeding box, thereby pushing the breeding box to the breeding rack.

[0076] See also Figure 3 and Figure 5In the embodiment of the utility model, the push-pull head assembly 243 includes a push-pull mounting seat 2431, a mounting pin 2432, a push-pull plate 2433 and a stop plate 2434. The push-pull mounting seat 2431 is connected to the telescopic end of the push-pull driving member 242 through a guide pin 245. The end of the push-pull mounting seat 2431 away from the telescopic end is provided with a mounting pin 2432. The push-pull plate 2433 can be deflected forward and backward on the mounting pin 2432 and extended downward. The force-applying surfaces of the push-pull plates 2433 of the two up-and-down loading mechanisms 240 are arranged in opposite directions, and the push-pull mounting seat 2431 is provided with a stop plate 2434 on the outer side of the push-pull plate 2433 arranged at the force-applying surface facing the connecting end. The force-applying surface is arranged facing the connecting end, so that the push-pull plate 2433 can apply an inward pulling force to the breeding box, and the push-pull plate 24 The stop plate 2434 on the outside of 33 can prevent the push-pull plate 2433 from rotating outward to ensure the stability of applying pulling force to the breeding box. Of course, this push-pull plate 2433 can rotate inward. When the push-pull driving member 242 extends toward the breeding box on the breeding rack, the push-pull plate 2433 can rotate inward to avoid the obstruction of the side plate of the breeding box and enter the breeding box; the push-pull mounting seat 2431 is provided with a stop plate 2434 on the inner side of the push-pull plate 2433 with the force-applying surface facing away from the connecting end, and the force-applying surface is arranged with the back of the connecting end, so that the push-pull plate 2433 can apply an outward thrust to the breeding box, and the stop plate 2434 on the inner side of the push-pull plate 2433 can prevent the push-pull plate 2433 from rotating inward to ensure the stability of applying thrust to the breeding box. Of course, this push-pull plate 2433 can rotate outward. Of course, the present invention is not limited to this, and the push-pull plate 2433 forming the force application surface can also be set to be deflected forward and backward through a motor or other suitable driving member.

[0077] In the embodiment of the utility model, the push-pull plate 2433 includes a rotating head 2435, a mounting bearing 2436 and a plate body 2437. The rotating head 2435 is rotatably sleeved on the mounting pin 2432 through the mounting bearing 2436. The plate body 2437 is connected to the rotating head 2435 and extends downward, and a force application surface is formed on the plate body 2437. The deflection setting of the push-pull plate 2433 on the mounting pin 2432 is realized by mounting the bearing 2436, which can further reduce friction and make the rotation smoother. Specifically, the force-applying surface of the plate body 2437 of the upper and lower downloading mechanism 240 for pulling is arranged to face the connecting end, and the force-applying surface of the plate body 2437 of the upper and lower downloading mechanism 240 for pushing is arranged to face away from the connecting end, and the push-pull mounting seat 2431 includes a seat body connecting plate and two seat body mounting plates, the two seat body mounting plates are arranged on the opposite sides of the telescopic end of the push-pull driving member 242, and are connected in series through the guide pin shaft 245, the seat body connecting plate connects the two seat body mounting plates, the two ends of the mounting pin shaft 2432 are respectively and one by one passed through the ends of the two seat body mounting plates away from the telescopic end of the push-pull driving member 242, and a stop ring is provided at the end of the mounting pin shaft 2432 extending out of the seat body mounting plate.

[0078] like Figures 2 to 4 As shown, in the embodiment of the utility model, the push-pull groove 244 is arranged with the front higher and the back lower in the direction from the connection end of the push-pull driving member 242 toward the telescopic end. It should be particularly noted that when the push-pull groove 244 is arranged in a guiding manner in the direction from the connection end toward the telescopic end, the end close to the connection end is defined as the front, and the end away from the connection end is defined as the back. That is, when the telescopic end of the push-pull driving member 242 is retracted, it will drive the push-pull head assembly 243 to be raised, so that after the upper and lower downloading mechanisms 240 for pulling pull the breeding box on the breeding rack to the place and transfer it to the supporting surface, the push-pull head assembly 243 will be separated from the breeding box and will not interfere with the subsequent transfer; and when the breeding box after feeding is transferred to the supporting surface, since the two upper and lower downloading mechanisms 240 remain in a retracted state, they will not interfere with the transfer of the breeding box.

[0079] In an embodiment of the utility model, the push-pull groove 244 includes a retraction stop groove section 2441, an inclined line-changing groove section 2442 and an extending push-pull groove section 2443 which are sequentially connected in the direction from the connecting end toward the telescopic end. The retraction stop groove section 2441 and the extending push-pull groove section 2443 are both extended in the horizontal direction, and the extending push-pull groove section 2443 is lower than the retraction stop groove section 2441, and the inclined line-changing groove section 2442 is inclined. That is, the push-pull groove 244 is approximately in a "Z" shape, and the horizontal length of the retracted stop groove section 2441 is much smaller than the horizontal length of the extended push-pull groove section 2443. When the breeding box needs to be pushed and pulled, the push-pull driving member 242 can drive the push-pull head assembly 243 to translate on the extended push-pull groove section 2443 to ensure the stability of the push-pull movement. After the push-pull movement is completed, the push-pull driving member 242 can drive the push-pull head assembly 243 to retract from the inclined line-changing groove section 2442 of the push-pull groove 244 to the retracted stop groove section 2441. Since the inclined line-changing groove section 2442 is higher in front and lower in the back in the direction from the connecting end to the telescopic end The inclined setting, and the retraction stop groove section 2441 is higher than the extended push-pull groove section 2443, so that the push-pull head assembly 243 of the upper and lower downloading mechanism 240 for pulling gradually separates from the breeding box after reaching the inclined line changing groove section 2442, and finally separates from the breeding box after reaching the retraction stop groove section 2441, and when the breeding box after feeding is transferred from the outside to the supporting surface, the push-pull head assembly 243 of the two upper and lower downloading mechanisms 240 are retracted to the retraction stop groove section 2441, so that the lower end of the push-pull head assembly 243 is at a distance from the breeding box during the transfer process, so as not to interfere with the transfer of the breeding box. Of course, the utility model is not limited to this, and the entire push-pull groove 244 can also be set as an inclined groove section with a smaller slope.

[0080] See also Figure 2 and Figure 3In the embodiment of the utility model, the push-pull frame 241 includes a push-pull connecting plate 246 and two push-pull mounting plates 247. The two push-pull mounting plates 247 are arranged at a relative interval and both have push-pull grooves 244. The push-pull connecting plate 246 connects the two push-pull mounting plates 247. The push-pull driving member 242 is placed between the two push-pull mounting plates 247. The connecting end of the push-pull driving member 242 is hinged to the two push-pull mounting plates 247 through a connecting pin 248. The telescopic end of the push-pull driving member 242 is arranged toward the breeding frame and is connected to the push-pull head assembly 243 through a guide pin 245 movably inserted into the push-pull grooves 244 of the two push-pull mounting plates 247. That is, both ends of the push-pull driving member 242 are respectively connected to the two push-pull mounting plates 247, so that the installation stability of the push-pull driving member 242 on the push-pull frame 241 can be ensured.

[0081] Furthermore, the upper ends of the two push-pull mounting plates 247 are formed with a first mounting bayonet, and the two ends of the connecting pin 248 on the connecting end of the push-pull driving member 242 extend out from the first mounting bayonet on the two push-pull mounting plates 247 in a one-to-one correspondence.
