[0002] Nowadays, more and more food waste treatment plants and livestock companies choose to use black soldier flies to treat food waste and livestock manure because the added value obtained by the method of black soldier fly digestion and conversion is relatively high. Black soldier flies absorb the nutrients in organic waste and convert them into high-value proteins of their own, and the excrement discharged by them is also a good fertilizer. Industrial automated breeding of black soldier flies is to raise black soldier flies in breeding boxes on breeding racks, which can make the best use of space and achieve large-scale breeding. This modern industrial automated breeding method of black soldier flies requires the use of a large number of automated equipment to complete breeding, and the breeding racks need to be transferred between various automated equipment. Manual transfer of breeding racks has a heavy labor burden, low work efficiency, and unpleasant odors will be generated at the black soldier fly breeding site.

Detailed Embodiment

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] Referring to Figure 1 and Figure 2 the breeding rack automatic transfer trolley of this embodiment includes a frame 1. The frame 1 includes a top frame 13, a bottom frame 11 at the top, and side frames 12 on both sides. The side frames 12 are connected between the top frame 13 and the bottom frame 11. A moving base 2 is fixedly connected to the bottom of the bottom frame 11, and a breeding rack translation pushing mechanism 3 is provided at the bottom of the top frame 13. A guiding mechanism 4 is provided at the top of the side frame 12. The frame 1 is welded by steel pipes, with light weight and good load-bearing capacity. The bottom of the bottom frame 11 and the moving base 2 are welded together. Two breeding rack guide rails 14 are provided on the bottom frame 11. When the breeding rack automatic transfer trolley is docked with other conveying devices or equipment, the breeding rack smoothly moves onto the breeding rack automatic transfer trolley of this embodiment along the breeding rack guide rail 14.

[0039] Reference Figures 3 to 7 On each side of the bottom of the moving base 2, there are two track wheels. The two track wheels at the front end of the moving base 2 are driving track wheels 21, and the two track wheels at the rear end are driven track wheels 22. A first driving mechanism for driving the rotation of the track wheels is provided on the moving base 2. The first driving mechanism includes a first motor 25 provided on the moving base 2. A rotating shaft is connected between the two track wheels at each end of the moving base 2. The rotating shaft at the front end is a driving rotating shaft 23, and the rotating shaft at the rear end is a driven rotating shaft 24. The output end of the first motor 25 is connected with a transmission shaft 28. Pulley 26 is sleeved on both the driving rotating shaft 23 and the transmission shaft 28, and the pulleys 26 of the two are connected by a flexible connecting member 27 for transmission. The pulley 26 can be a belt pulley, and the flexible connecting member 27 can be a synchronous belt. In this embodiment, belt pulleys are sleeved on both the driving rotating shaft 23 and the transmission shaft 28, and the belt pulleys of the two are connected by a synchronous belt for transmission. When the first motor 25 rotates, it drives the driving rotating shaft 23 to rotate through the synchronous belt and the pulley, so that the two driving track wheels 21 rotate synchronously, and the two driven track wheels 22 follow, thus driving the moving base 2 to move, and then making the automatic transfer trolley of the breeding rack move automatically.

[0040] First stoppers 4 are provided on the side beams on both sides of the moving base 2. The first stopper 4 includes a first stopper block 41 and a second telescopic device 42 below the vertical first stopper block 41. The first stopper block 41 is located on the upper side of the side beams on both sides of the bottom frame 11. The top end of the telescopic rod of the second telescopic device 42 is fixedly connected to the bottom of the first stopper block 41. A first stopper slot 411 is opened at the top of the first stopper block 41 along the extending direction of the first stopper block 41. The second telescopic device 42 can be an electric push rod. In order to facilitate the bottom side beam of the breeding rack 7 to be inserted into the first stopper slot 411, the longitudinal section of the first stopper slot 411 is trapezoidal, and the width of the first stopper slot 411 gradually decreases from top to bottom. A notch 412 is opened at the middle top surface of one side wall of the first stopper slot 411. When the bottom side beam of the breeding rack 7 is inserted into the first stopper slot 411, the reinforcing beam in the middle of the bottom surface of the breeding rack 7 is inserted into the notch 412.

[0041] At both ends of the bottom of the first stop block 41, guide shafts 43 are vertically connected. Holes for the guide shafts 43 to pass through are provided on the side beams of the bottom frame 11. A guide sleeve 44 is sleeved on the guide shaft 43, and the guide sleeve 44 can be a linear bearing. The guide sleeve 44 is located below the side beam of the bottom frame 11 and is vertically fixed on the side beam of the bottom frame 11. The guide shaft 43 can slide up and down through the guide sleeve 44 and the hole on the side beam of the bottom frame 11, and the guide shaft 43 plays a guiding role when the first stop block 41 moves up and down. When the cultivation rack 7 is transported onto the mobile base, the second telescopic device 42 is activated, and the telescopic rod extends, driving the first stop block 41 to rise. The first stop card slot 411 just catches on the side beam of the bottom frame of the cultivation rack 7, making the cultivation rack 7 immovable and able to keep the cultivation rack 7 from slipping when the mobile trolley moves. At this time, the mobile trolley starts to move, taking the cultivation rack 7 to the designated position; after reaching the position, the second telescopic device 42 resets, and the telescopic rod drives the stop block 41 to descend, disengaging from the frame of the cultivation rack 7, so that the cultivation rack 7 is released. Therefore, the cultivation rack stopper of the present invention effectively avoids the problem that the cultivation rack slides relative to the bottom frame and slips when the cultivation rack automatic transfer trolley moves.

[0042] Refer to the appendix Figures 8 to 10 , the cultivation rack translation and pushing mechanism 3 is used to drag the cultivation rack 7 into or out of the cultivation rack automatic transfer trolley. The cultivation rack translation and pushing mechanism 3 includes a base plate 31. A translation slide 32 is slidably arranged at the bottom of the base plate 31. Slide rails 311 are provided on both side edges of the bottom of the base plate 31. Sliders 326 are provided at both ends of the top of the mounting plate 321, and the sliders 326 are slidably connected to the corresponding slide rails 311. A second driving mechanism 33 for driving the translation slide 32 to slide along the base plate 31 is provided on the base plate 31. The translation slide 32 includes a mounting plate 321 slidably connected to the base plate 31. A first telescopic device 322 is provided on the mounting plate 321. A pushing block 323 is provided at the bottom of the mounting plate 321. The end of the telescopic rod of the first telescopic device 322 passes through the mounting plate 321 and is fixedly connected to the pushing block 323. A pushing card slot 3233 is provided at the bottom of the pushing block 323. The second telescopic device 322 can be an electric push rod.

[0043] Refer to Figure 10 , the pushing block 323 can adopt the following structure: The pushing block 323 includes a horizontal block 3231. Vertically downward connecting vertical blocks 3232 are provided at both ends of the horizontal block 3231. A pushing card slot 3233 is provided at the bottom of the vertical block 3232. A guide shaft 324 is vertically connected to the top surface of the horizontal block 3231. The guide shaft 324 passes through the mounting plate 321. A guide sleeve 325 is sleeved on the guide shaft 324, and the guide sleeve 325 is fixedly connected to the mounting plate 321. The guide sleeve 325 can be a linear bearing.

[0044] The second driving mechanism 33 includes a second motor 331 disposed on the base plate 31, and driving wheels 334 are provided on both sides of the bottom of one end of the base plate close to the second motor 331, and the two driving wheels 334 are respectively fixedly mounted on the two ends of a driving shaft 333, and driven wheels 336 are provided on both sides of the bottom of the other end, and the two driven wheels 336 are fixedly mounted on the two ends of a driven shaft 335, and the output end of the reducer connected to the driving shaft 333 and the second motor 331 is fixedly connected, and the two driving wheels 334 are connected to the driven wheels 336 on the corresponding side through a flexible connector 337, and the two ends of the top surface of the mounting plate 321 are respectively fixedly connected to the flexible connectors 337 on both sides. The driving shaft 333 and the driven shaft 335 are both rotatably connected to the bottom of the base plate 31 through a bearing seat and a bearing 338.

[0045] Both the driving wheel 334 and the driven wheel 336 can use pulleys, and the soft connection part 337 can use a synchronous belt. When the second motor 331 rotates, the driving shaft 333 rotates, and the driving wheel 336 is driven to rotate through the driving shaft 333. The driving wheel 336 drives the driven wheel to rotate through the soft connection part 337, so that the soft connection part 337 rotates, driving the translation slide 32 to move.

[0046] Reference Figures 11 to 12 The guide mechanism 5 includes a guide groove 52 surrounded by a fixed plate 51, the guide groove 52 is located at the inner side of the top of the side frame 12 and is open toward the frame 1, and a plurality of guide wheels 53 are arranged in the guide groove 52 for rotation at intervals. When the breeding rack 7 enters the breeding rack automatic transfer trolley of the present invention, the upper side beam of the breeding rack 7 moves along the guide wheel 53 and enters, and is straightened at the upper part of the breeding rack 7, so that the breeding rack 7 is positioned more accurately.

[0047] A second stopper 6 is provided in the middle of the guide groove 52, and the second stopper 6 includes a second stopper block 61 and a third telescopic device 62. The second stopper block 61 is provided in the guide groove 52, and the third telescopic device 62 is provided on the outer side of the bottom plate of the guide groove 52. The end of the telescopic rod of the third telescopic device 62 is fixedly connected to a side wall of the second stopper block 61, and a second stopper slot is provided on the side wall of the second stopper block 61 facing the inside of the frame 1. The third telescopic device 62 can adopt an electric push rod.

[0048] The other structures of the second stop block 61 are the same as those of the first stop block described above. For example, a guide shaft 63 is connected to one side wall of the second stop block, and a guide sleeve 64 is sleeved on the guide shaft 63. This will not be described in detail here. When the breeding rack 7 is pushed onto the bottom frame 11, the third telescopic device 62 can be actuated to push the second stop block 61 out, clamp the upper side beam of the breeding rack 7, and keep the breeding rack 7 immobile. After being transported to the location, the third telescopic device 62 retracts, driving the second stop block 61 to retract, loosening the breeding rack 7, and facilitating the unloading of the breeding rack 7.

[0049] Reference Figures 15 to 16, the working principle of the automatic transfer cart for the breeding rack of the present invention is as follows:

[0050] When the breeding rack 7 needs to be transferred, when the breeding rack 7 needs to be dragged into or pushed out of the automatic transfer cart for the breeding rack of the present invention for movement, the first telescopic device 322 acts, driving the pushing block 323 to descend, so that the pushing card slot 3233 just catches onto the top frame cross beam of the breeding rack 7. At this time, the second motor 331 of the second driving mechanism 33 starts, the driving shaft 333 rotates, drives the driving wheel 334 to rotate through the driving shaft 333, the driving wheel 334 drives the driven wheel 336 to rotate through the flexible connecting piece 337, making the flexible connecting piece 337 operate, driving the translation sliding table 32 to move, and the pushing block 323 of the translation sliding table 32 drives the breeding rack 7 to move together. After the breeding rack 7 reaches the position, the translation sliding table 32 stops moving, the pushing block 323 rises, and disengages from the breeding rack 7, thus automatically dragging the breeding rack onto the moving base. At this time, the first stopper 4 and the second stopper 6 act, respectively clamping the bottom side beam and the upper side beam of the breeding rack 7 to keep the breeding rack 7 stationary. Then the first driving mechanism operates, driving the moving base 2 to travel on the ground track 8, so that the breeding rack 7 flows among various devices along the ground track 8. After being transported to the position, the first stopper 4 and the second stopper 6 are released, releasing the breeding rack 7. The second motor 331 of the second driving mechanism 33 reverses, causing the translation sliding table 32 to slide outwards, and the pushing block 323 automatically pushes the breeding rack 7 out of the bottom frame 11, realizing automatic unloading. It realizes automatic loading and unloading and automatic transfer of the breeding rack, greatly reducing the manual labor burden, and has a fast working speed and high working efficiency.

[0051] An electric control cabinet 9 can be arranged on the side frame 12. A controller is arranged inside the electric control cabinet 9. The controller can adopt programmable controllers such as PLC, single-chip microcomputer, and industrial control computer. The above-mentioned components such as the first motor and the second motor are electrically connected to the controller to achieve automatic control. Industrial controllers such as PLC and single-chip microcomputer itself have built-in logic control functions. Using industrial controllers such as PLC and single-chip microcomputer to achieve some logic control, the selection of electrical components and the electrical connection method are all well-known technologies in the art and will not be elaborated here.

[0052] The above is an example of the best implementation mode of the present invention. The parts not described in detail are all common general knowledge of those skilled in the art.
