Description

Technical Field

[0001] The present invention relates to the technical field of separation devices, and particularly relates to an efficient silkworm excrement separation device and method for the production of Beauveria bassiana Background Art

[0002] As is well known, an efficient silkworm excrement separation device for the production of Beauveria bassiana is an auxiliary device used to quickly separate Beauveria bassiana, silkworm excrement and mulberry leaves after the breeding of Beauveria bassiana is completed, so as to separately obtain Beauveria bassiana and silkworm excrement for further processing

[0003] After retrieval, the patent with the Chinese patent publication number CN118543534A and the patent with the Chinese patent publication number CN119702423A respectively disclose a medicinal Beauveria bassiana powder separation device and a Beauveria bassiana automatic sorting device and sorting method. The former is roughly described as including an open shell, an annular screening mesh is arranged in the shell, and the internal space of the shell is divided into an insect material cavity and a powder material cavity by the screening mesh. An inner cylinder is arranged in the insect material cavity, and at least one conical section is provided on the outer part of the inner cylinder. The screening mesh fits the conical section and forms an annular equal-gap falling section in the insect material cavity. The gap of the falling section is larger than the maximum size of a single Beauveria bassiana, and the gap of the falling section is smaller than three times the maximum size of a single Beauveria bassiana. A first rotating brush group that brushes the surface of the screening mesh is arranged in the powder material cavity. The fungal spores on the surface of Beauveria bassiana in the falling section are separated by the first rotating brush group and discharged from the material distribution port in the powder material cavity. The Beauveria bassiana after brushing is discharged from the insect material port at the lower part of the insect material cavity. The latter is roughly described as including a support assembly, a feeding assembly is connected to the support assembly, a sorting assembly is connected to one end of the feeding assembly, a discharging assembly is connected to the end of the sorting assembly far from the feeding assembly, and a conveying assembly for moving the sorted Beauveria bassiana is connected to the outer periphery of the sorting assembly. Through the mutual cooperation between the sorting assembly and the elastic assembly, the sorting of Beauveria bassiana with different volumes is realized. During the sorting process, according to the impurity situation in the conveying assembly, the sorting situation of Beauveria bassiana in the sorting assembly is judged, that is, when the number of impurities entering the intermediate holes increases, the elastic assembly is used to increase the residence time of Beauveria bassiana in the primary hole area

[0004] Although the above two sets of existing technical solutions can both be applied to the production process of Beauveria bassiana, most of the formation stage of Beauveria bassiana is after the fourth molting of live silkworms. It can be seen that a certain time stage of mulberry leaf feeding is required in this breeding process. During the breeding process of live silkworms, due to the large breeding density, it is generally difficult to clean the remaining leaf stalks after the mulberry leaves are placed. And during the process of live silkworms being infected with bacteria to form Beauveria bassiana, it is inevitable that live silkworms will drill under the mulberry leaves in a surviving state. Therefore, simply relying on the above two sets of existing technical solutions, it is very easy to have residues of Beauveria bassiana and silkworm excrement in the mulberry leaf sandwich, and the separation effect needs to be further improved Summary of the Invention

[0015] A separation method for an efficient silkworm excrement separation device for Beauveria bassiana production includes the following steps: S1. When in use, firstly, the materials to be separated, which are composed of white silkworm, silkworm feces and mulberry leaves, are placed in the alternating feeding assembly, and the materials to be separated are adjusted relative to the cloth structure through the alternating feeding assembly, so that the materials to be separated enter the gantry, and then the electric lifting rod works to control the insertion frame to form a height reduction in the gantry. In this process, under the action of the follow-up elastic component, the rotating plate will first rotate into an upright state, and then form a height reduction until the magnetic mounting assembly can form a corresponding lift for the materials to be separated in the alternating feeding assembly; S2, then the electric lifting rod drives the insertion frame to rise, so that the material to be separated is first lifted and then moved from a horizontal state to an upright state. During this process, the screening net will rise with the material to be separated, so as to receive the white silkworm, silkworm excrement and mulberry leaves falling from the material to be separated, and screen the white silkworm, silkworm excrement and mulberry leaves respectively; S3. After the rotating plate rotates and rises, it will further rise, and during the rising process of the rotating plate, the insertion belt plate will be relatively inserted into the material to be separated. After the insertion belt plate is inserted to a suitable position, the electric lifting rod is controlled to stop working, so that the material to be separated enters a highly static state; S4, then start the vibration motor, the vibration motor is powered on to realize the reciprocating motion of the sliding frame relative to the suspension frame, the sliding frame drives the multiple insertion belt plates to move when moving, the insertion belt plates move to realize the shaking of the material to be separated, so that the multiple layers of mulberry leaves in the material to be separated are shaken and auxiliary peeling is formed, so that the white silkworm and silkworm feces between two adjacent layers of mulberry leaves in the material to be separated are shaken off and separated; S5. The materials to be separated that are shaken off will eventually fall on the screen net to form screening separation. After the separation is completed, when the electric lifting rod controls the rotating plate to lower its height and rotate and fall, the screen net will form a centralized external discharge of the remaining tailings after screening for use in the next screening, and the rotating plate that has rotated and fallen will lift up the next batch of materials to be separated again to achieve the shaking off and screening operations of the next batch of materials to be separated.

[0017] (2) In the present invention, through the design of the shaking structure, corresponding insertion interference and shaking are formed for the material to be separated that is transported by the cloth structure, thereby improving the separation effect of the material to be separated.

A servo motor 23 is installed on the short suspension frame 18, and the servo motor 23 is used to drive the rotation of the driving rotating frame 20. Through the provision of the first feeding tray 21 and the second feeding tray 22, it is convenient for the relative loading of the material to be separated and the preparation of the material to be separated relative to the magnetic mounting component. The magnetic mounting component includes a mounting plate 24, a first bottom bracket 25, and a second bottom bracket 26. The mounting plate 24 is fixedly connected to the bottom end of the rotating plate 6. Four insertion cylinders 27 are fixedly connected to the bottom end of the mounting plate 24.

Control the electromagnets 28 to enter the energized state,An electromagnetic field will be generated around the electromagnet 28. Thereafter, when the insertion cylinder 27 is inserted relative to the first insertion groove 29, the electromagnet 28 can magnetically attract the round iron block 31 in the first insertion groove 29. And under the action of this magnetic attraction, when the insertion cylinder 27 is raised, the first bottom bracket 25 can be lifted out of the first feeding tray 21, and the materials to be separated on the first bottom bracket 25 can also be lifted out synchronously.

[0023] It should be further explained that the gantry 3 is fixedly connected to the suspension bracket 7, the suspension bracket 7 is slidably connected to the lifting frame 8, the screening net 1 is installed in the lifting frame 8, and a follow-up lifting component for driving the lifting frame 8 is installed on the suspension bracket 7. The follow-up lifting component matches the rotating plate 6. The follow-up lifting component includes a fixed bar frame 32 and two transmission bar frames 33. The two transmission bar frames 33 are respectively rotatably connected to the two ends of the fixed bar frame 32, and the fixed bar frame 32 is fixedly connected to the top of the suspension bracket 7. A driving plate frame 34 is connected between the two transmission bar frames 33. The driving plate frame 34 is slidably connected to the suspension bracket 7. The bottom end of the driving plate frame 34 is provided with a pushing surface 35 matching the rotating plate 6. The two transmission bar frames 33 are both connected to the lifting frame 8, and the two transmission bar frames 33 are both opened There are driving bar holes 36 and transmission bar holes 37, and driving rods 38 are connected in the two driving bar holes 36. The two driving rods 38 are fixedly connected to the driving plate frame 34, and the two transmission bar holes 37 are connected to the transmission rods 39. The two transmission rods 39 are fixedly connected to the lifting frame 8. When the rotating plate 6 rotates and rises, and the rotating plate 6 pushes the pushing surface 35, the two driving rods 38 are pushed synchronously under the transmission action of the driving plate frame 34. The two driving rods 38 respectively drive the two transmission bar frames 33 to rotate relative to the fixed bar frame 32. The rotating and raised driving plate frame 34 will realize the follow-up rise of the lifting frame 8 through the transmission rod 39, so as to achieve the rise of the screening net 1 and the relative distance close to the material to be separated that has entered the upright state, thereby raising the screening net 1. In order to achieve the receiving effect of the high screening net 1 on the separated materials, the lifting frame 8 is rotatably connected with two rotating couplings 40, and a mounting frame 41 is fixedly connected between the two rotating couplings 40. The screening net 1 is fixedly connected in the mounting frame 41. The bottom end of the lifting frame 8 is fixedly connected with two limit frames 42, and the two limit frames 42 are both connected with tension springs 43, and the two tension springs 43 are both connected with the mounting frame 41. A pressing push frame 44 is fixedly connected to the mounting frame 2, and the pressing push frame 44 matches the screening net 1.

Under the coordinated action of the frame 42 and the tension spring 43, the screen mesh 1 presents a horizontal posture front and back, and when the screen mesh 1 is synchronously lowered with the lifting frame 8, the rear end of the screen mesh 1 is pushed by the contact force transmission ball 45, and then the screen mesh 1 will enter a posture with a low front and a high rear, so as to facilitate the centralized cleaning of the screened residual materials on the screen mesh 1. A flat plate 46 is fixedly connected to the top of the mounting frame 2, and a tailings recovery port 47 and a plurality of partitioned material passing ports 48 are provided on the flat plate 46.

The shaking structure includes a sliding frame 9, and the sliding frame 9 is slidably connected to the suspension bracket 7.A vibration motor 10 is installed at the top of the sliding frame 9. A plurality of inserting belt plates 11 are fixedly connected to the bottom end of the sliding frame 9. A plurality of reset springs 12 are fixedly connected between the sliding frame 9 and the suspension bracket 7. Through the design of the jitter structure, an insertion interference and jitter are formed for the materials to be separated conveyed by the cloth structure, improving the separation effect of the materials to be separated. Moreover, during the separation process, the mulberry leaves in multiple layers in the materials to be separated can be relatively peeled off, and the separation effect is better.

[0024] The electric lifting rod 5, vibration motor 10, servo motor 23, and electromagnet 28 in this embodiment are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them without improving their structures and functions. For those skilled in the art, their setting methods, installation methods, and electrical connection methods can be debugged and operated as required in their user manuals, and thus will not be elaborated here.

[0025] In summary, the working principle of the efficient silkworm excrement separation device and method for Beauveria bassiana production is as follows. Before use, first place the efficient silkworm excrement separation device for Beauveria bassiana production at the location where it is needed, and install control circuits for the electric lifting rod 5, vibration motor 10, servo motor 23, and electromagnet 28. When screening, first place the material to be separated composed of Beauveria bassiana, silkworm excrement, and mulberry leaves in the alternating feeding component. Through the alternating feeding component, the material to be separated is adjusted relative to the cloth structure, so that the material to be separated enters the gantry 3. During this process, the servo motor 23 is powered on and runs to drive the rotation of the active turntable 20. With the auxiliary support of the follower turntable 19, the alternating change of the first feeding tray 21 and the second feeding tray 22 can be realized. That is, when the first feeding tray 21 is in the last position, the second feeding tray 22 enters the gantry 3 to form a feeding in place matching the mounting plate 24. Conversely, when the second feeding tray 22 is in the last position, the first feeding tray 21 enters the gantry 3. When the first feeding tray 21 is located at the last side, first load the first bottom bracket 25 into the first feeding tray 21 and then load the material to be separated. During the loading process, the material to be separated should form a complete coverage on the first bottom bracket 25. When the second feeding tray 22 is located at the last side, first load the second bottom bracket 26 into the second feeding tray 22 and then load the material to be separated. The first bottom bracket 25 and the second bottom bracket 26 have the same structure. The "first" and "second" here are distinguishing words added for convenience of distinction. The "first" and "second" in the first feeding tray 21 and the second feeding tray 22 are also distinguishing words. After that, the electric lifting rod 5 works to control the insertion frame 4 to lower in height within the gantry 3. During this process, under the action of the follower elastic component, the rotating plate 6 will first rotate into the vertical state, and then lower in height. That is, when the lifting frame 8 lowers in height, the rotating plate 6 will synchronously lower relative to the gantry 3. During this process, the linkage spring 15 will be stretched. Under the stretching action of the linkage spring 15, the rotating plate 6 will change from the horizontal posture to the vertical state, and the corresponding insertion cylinder 27 will also enter the vertical state from the horizontal state to attach Figure 1 As an example, at this time, the insertion cylinder 27 in the vertical state happens to be vertically aligned with the second insertion slot 30. After that, the electric lifting rod 5 continues to work to further lower the insertion frame 4 until the insertion cylinder 27 that synchronously lowers with the insertion frame 4 is inserted into the first insertion slot 29. After that, the electromagnet 28 is energized to generate an electromagnetic field, and the mutual connection between the insertion cylinder 27 and the first bottom bracket 25 can be realized. After that, when the insertion cylinder 27 rises, the material to be separated can be lifted, that is, the magnetic mounting component can lift the material to be separated in the alternating feeding component correspondingly.

[0026] Furthermore, the electric lifting rod 5 drives the insertion frame 4 to rise, so that the material to be separated is first lifted and then enters the upright state from the horizontal state, that is, when the rotating plate 6 is raised relative to the gantry 3, under the action of the linkage spring 15, the rotating plate 6 will rotate from the upright state to restore the horizontal posture. Since the material to be separated is covered and laid relative to the second bottom bracket 26, the insertion cylinder 27 will penetrate and insert relative to the material to be separated, and in the process of breeding white silkworms, mulberry leaves will be laid flat and fed for many times. In this way, in the stacked state of white silkworms, silkworm feces and multiple layers of mulberry leaves, the material to be separated as a whole presents a flocculent structure with multiple layers alternatingly distributed. Therefore, after the insertion cylinder 27 passes through the material to be separated, when the insertion cylinder 27 enters the horizontal state from the upright state, the material to be separated will be mounted by the insertion cylinder 27, so that it is more difficult to fall, while the white silkworms and silkworm feces between the multiple layers of mulberry leaves in the material to be separated are more likely to fall. In this process, the screening net 1 will accompany the material to be separated. When the rotating plate 6 is rotated and raised, and the rotating plate 6 pushes the pushing surface 35, the two driving rods 38 will be pushed synchronously under the transmission action of the driving plate frame 34, so that the two driving rods 38 respectively drive the two driving plate frames 34 to rotate relative to the fixed bar frame 32, and the rotating and raised driving plate frame 34 will realize the follow-up rise of the lifting frame 8 through the transmission rod 39, so as to achieve the rise of the screening net 1 and the relative distance relative to the materials to be separated that have entered the upright state, thereby improving the receiving effect of the screening net 1 on the materials to be separated. In the process of further rising after the rotating plate 6 is rotated and raised, the rising of the rotating plate 6 will cause the insertion belt plate 11 to form a relative insertion of the materials to be separated. After the insertion belt plate 11 is inserted to a suitable position, the electric lifting rod 5 is controlled to stop working, so that the materials to be separated enter a highly static state.

[0027] Further, the vibration motor 10 is started later. When the vibration motor 10 is powered on and operates, it realizes the reciprocating movement of the sliding frame 9 relative to the suspension bracket 7. When the sliding frame 9 moves, it drives the plurality of insertion belt plates 11 to move. The movement of the insertion belt plates 11 realizes the jitter of the material to be separated, causing jitter and auxiliary peeling between the multiple layers of mulberry leaves in the material to be separated, and realizing the shaking and separation of the white muscardine silkworms and silkworm excrement between the adjacent two layers of mulberry leaves in the material to be separated. The material to be separated that is shaken and separated will finally fall on the screening mesh 1 to form screening separation. After the separation is completed, when the electric lifting rod 5 controls the height of the rotating plate 6 to decrease and rotate and fall again, the electromagnet 28 is controlled to be powered off so that the electromagnetic field disappears. Thereafter, the corresponding second bottom bracket 26 will slide relative to the insertion cylinder 27, and the second bottom bracket 26 will fall on the screening mesh 1 under the action of its own gravity. And during the process of the rotating plate 6 falling, the driving force acting on the driving plate frame 34 fails, and the screening mesh 1 will reset by decreasing in height under the action of its own gravity. During the reset process, the rear end of the screening mesh 1 will contact the contact transmission ball 45, and with the auxiliary support of the contact transmission ball 45, the rear end of the screening mesh 1 will rise while the front end will decrease, so that the remaining tailings on the screening mesh 1 and the corresponding second bottom bracket 26 are centrally discharged for use in the next screening. The second bottom bracket 26 that falls on the screening mesh 1 will be guided by the extension guide plate 49 and fall into the tailing recovery port 47 for recycling. And the rotating plate 6 that rotates and falls will lift the next batch of materials to be separated again to realize the shaking and screening operations of the next batch of materials to be separated. During actual use, the partition feeding port 48 and the extension guide plate 49 are correspondingly installed with a bag structure or a box structure for storage to assist in the storage of the screened materials. For the setting of the four insertion cylinders 27, this is only a specific quantity description for convenience of description. In the actual application state, in order to realize the effective hooking of the insertion cylinder 27 with the material to be separated, the number of insertion cylinders 27 can be increased as appropriate, so that the insertion cylinder 27 is inserted into more positions of the residual mulberry leaves in the material to be separated, increasing the density of the insertion points on the material to be separated, enabling the insertion cylinder 27 to form more hooking support points for the residual mulberry leaves in the material to be separated, improving the hooking effectiveness of the insertion cylinder 27 for the residual mulberry leaves in the material to be separated, and reducing the dropping of the residual mulberry leaves in the material to be separated when being hooked by the insertion cylinder 27. At the same time, when the number of insertion cylinders 27 increases, the number of corresponding first insertion slots 29 and the number of second insertion slots 30 should also be increased accordingly.
