Description

Technical Field

[0001] The utility model belongs to the technical field of fly breeding, and relates to a fly larva hatching and breeding system. Background Art

[0002] Flies are widely sourced and large in number. They are complete metamorphosis insects, and their life cycle includes four stages: eggs, larvae (fly maggots), pupae, and adults. Among them, the larvae of flies have comprehensive nutritional components. They are not only high in protein, low in sugar and low in fat, but also contain rich mineral elements, vitamins, trace elements and antibacterial active substances, and are high-quality animal protein feeds. In addition, the larvae of flies have extensive utilization values in the fields of medicine, health care and food.

[0003] Fly larva hatching and breeding is a technology in the process of fly breeding, which collects the fly eggs laid by flies and then hatches the fly eggs into larvae for utilization. At present, fly larva hatching and breeding in China is mainly based on artificial breeding. For example, a drawer-type maggot breeding cabinet disclosed in a patent document (application number: 201520641808.8) includes a rectangular frame, and a plurality of horizontal partition layers are welded or screwed inside the frame. Each horizontal partition layer is an angle iron long square frame, and drawers are respectively placed inside the partition layers. Except for the bottom surface of the frame, the side surfaces and the top of the remaining drawers are closed with screen meshes or glass, and a maggot receiving basin is arranged at the bottom surface of the frame.

[0004] When this device is used for fly larva hatching and breeding, workers need to cultivate the obtained fly eggs in an ordinary plastic basin for one night every day, and then place the plastic basin containing the collected fly eggs into the drawer-type maggot breeding cabinet the next day to hatch the fly eggs into fly larvae. When the fly larvae are mature, they are allowed to climb out naturally and fall into the maggot receiving basin below. Since this breeding method requires a large amount of manual intervention, it is time-consuming and laborious, with low breeding efficiency, low mechanization and automation levels, and it is impossible to achieve large-scale, industrialized and efficient production of fly larvae. Summary of the Invention

[0005] The purpose of the utility model is to address the above problems existing in the prior art and propose a fly larva hatching and breeding system. The utility model solves the problems of low automation degree and breeding efficiency of the existing fly larva hatching and breeding method, and it is difficult to achieve large-scale production.

[0006] The object of the present utility model can be achieved by the following technical solutions: A fly larva hatching and breeding system, comprising a fly breeding room and a breeding room, characterized in that an egg-laying conveying line connected end to end is provided in the fly breeding room, a breeding conveying line connected end to end is provided in the breeding room, accommodation trays are provided on both the egg-laying conveying line and the breeding conveying line, the number of accommodation trays on the breeding conveying line is more than that on the egg-laying conveying line, the fly larva hatching and breeding system further comprises a conveying and transferring device, both the egg-laying conveying line and the breeding conveying line can convey their respective accommodation trays to the conveying and transferring device, the conveying and transferring device comprises a first manipulator and a second manipulator that can reciprocate between the egg-laying conveying line and the breeding conveying line, the first manipulator can transfer the accommodation tray on the egg-laying conveying line to the breeding conveying line through its own movement, and the second manipulator can transfer the accommodation tray on the breeding conveying line to the egg-laying conveying line through its own movement.

[0007] In this system, by respectively arranging an egg-laying conveying line and a breeding conveying line in the fly breeding room and the breeding room, flies lay eggs in the accommodation trays in the fly breeding room. After the egg-laying is completed, all the accommodation trays with collected fly eggs on the egg-laying conveying line are sequentially transferred to the breeding conveying line through the first manipulator for breeding. After the fly eggs hatch into larvae, the larvae are poured out of the accommodation trays, and the larvae are collected and utilized, forming empty accommodation trays. After the empty accommodation trays are cleaned, egg-laying materials suitable for flies to lay eggs are laid in the accommodation trays. The egg-laying materials are, for example, wheat bran added with an appropriate amount of water. While the first manipulator transfers the accommodation trays with fly eggs on the egg-laying conveying line to the breeding conveying line, the second manipulator also synchronously transfers the accommodation trays filled with egg-laying materials to the egg-laying conveying line, and so on in a cycle.

[0008] Obviously, through the form of the egg-laying conveying line, the breeding conveying line and the cooperating conveying and transferring device, the accommodation trays can be automatically transferred between the fly breeding room and the breeding room, realizing the automation of the egg-laying process and the breeding process, greatly reducing the intervention of manual labor, and having a high degree of automation. The conveying and transferring device adopts a structure of two manipulators cooperating with each other. It can transfer the accommodation trays on the egg-laying conveying line to the breeding conveying line while synchronously transferring the egg-laying trays on the breeding conveying line to the egg-laying conveying line, so as to greatly improve the efficiency of the exchange and transfer of the accommodation trays, and thus make this system have a high degree of automation and breeding efficiency. In addition, both the egg-laying conveying line and the breeding conveying line adopt a structure connected end to end, and the accommodation trays continuously move along a closed loop on the egg-laying conveying line and the breeding conveying line, enabling this system to realize continuous egg-laying operations, breeding operations and accommodation tray transfer operations, thereby improving the automation degree and breeding efficiency of the system, and enabling this system to achieve large-scale production.

[0009] In addition, the habit of flies is to lay eggs generally at 9 o'clock and 17 o'clock. That is to say, the accommodation trays need to be exchanged twice a day. For the first time, the accommodation trays need to be sent into the fly breeding room before 9 o'clock, and for the second time, the accommodation trays need to be sent into the fly breeding room before 17 o'clock. However, the time for fly eggs in the breeding room to hatch into larvae is generally 6 - 8 hours. That is to say, there is a time difference between the time for fly eggs in the breeding room to hatch into larvae and the time for flies in the fly breeding room to complete egg laying. Moreover, the time for fly eggs in the breeding room to hatch into larvae will also change due to factors such as temperature and humidity. During the operation of the system, when the exchange and transfer of accommodation trays are required, the fly eggs on the breeding conveyor line may not have hatched into larvae yet. At this time, if the number of accommodation trays on the egg receiving conveyor line is equal to that on the breeding conveyor line, then it is necessary to wait for the larvae to hatch into adults before the accommodation trays can be exchanged, which will greatly affect the breeding efficiency. In this system, since the number of accommodation trays on the breeding conveyor line is greater than that on the egg receiving conveyor line, when the exchange and transfer of accommodation trays are required, there will always be some empty trays left on the breeding conveyor line to exchange with the accommodation trays on the egg receiving conveyor line, without having to wait for the completion of the hatching process in the breeding room. Therefore, the equipment is ensured to have a higher breeding efficiency. For those accommodation trays on the breeding conveyor line where the fly eggs have not been hatched yet, they remain in the breeding room until the eggs hatch. Then, the materials in the accommodation trays are poured out, and the accommodation trays are cleaned to form empty accommodation trays waiting for exchange.

[0010] In summary, through the cooperation of the egg receiving conveyor line, the breeding conveyor line and the conveying and transferring device, and by combining the ratio of the number of accommodation trays on the breeding conveyor line and the egg receiving conveyor line, this fly larva hatching and breeding system can greatly improve the automation degree and breeding efficiency of the fly larva hatching and breeding system, enabling this system to meet the requirements of large-scale production.

[0011] In the above fly larva hatching and breeding system, the egg receiving conveyor line and the breeding conveyor line are parallel to each other and have opposite conveying directions at the conveying and transferring device, and the moving directions of the first manipulator and the second manipulator are perpendicular to the conveying direction of the egg receiving conveyor line at the conveying and transferring device.

[0012] When the conveying and transferring device is working, the first manipulator and the second manipulator respectively grab a set of accommodating trays from the egg-laying conveying line and the breeding conveying line. At this time, a vacancy is formed on the egg-laying conveying line and the breeding conveying line respectively. At this time, since the conveying directions of the egg-laying conveying line and the breeding conveying line are opposite at the conveying and transferring device, after the egg-laying conveying line and the breeding conveying line respectively run one stroke, the vacancy on the egg-laying conveying line can be aligned with the second manipulator, and at the same time, the vacancy on the breeding conveying line is aligned with the first manipulator. Then, the first manipulator transfers the accommodating tray with fly eggs to the vacancy on the breeding conveying line, and the second manipulator transfers the accommodating tray with egg-laying materials to the vacancy on the egg-laying conveying line. In this way, an exchange transfer of the accommodating trays is completed. This cycle continues until all the accommodating trays on the egg-laying conveying line are exchanged with an equal number of accommodating trays on the breeding conveying line.

[0013] The egg-laying conveying line and the breeding conveying line are parallel to each other at the conveying and transferring device, and the moving directions of the first manipulator and the second manipulator are perpendicular to the moving direction of the egg-laying conveying line at the conveying and transferring device. This design enables the first manipulator and the second manipulator to have the shortest moving stroke and a fixed moving distance during each transfer operation, thereby improving the stability, reliability and transfer efficiency of the device operation.

[0014] In the above fly larva hatching and breeding system, the fly larva hatching and breeding system further includes a fly supplement room, the fly supplement room has a first door and a second door both communicating with the breeding fly room, a fly supplement conveying line is provided in the breeding fly room, and a fly supplement tray that can move along its conveying direction is provided on the fly supplement conveying line. One section of the fly supplement conveying line enters the fly supplement room from the first door and then returns to the breeding fly room from the second door.

[0015] The flies in the breeding fly room will die continuously. By setting the fly supplement conveying line to pass through the fly supplement room, the staff can supplement the fly pupae in the fly supplement tray, and then rely on the fly supplement conveying line to supplement the pupae into the breeding fly room. The pupae hatch into flies in the breeding fly room, so as to ensure that the number of flies in the breeding fly room meets the requirements, ensure the egg-laying amount and egg-laying efficiency, and then improve the breeding efficiency of the system. At the same time, it also makes the fly supplement process more automated. Since the breeding fly room is full of flies, by setting the fly supplement room, the staff can perform fly supplement operations in the fly supplement room, which is more convenient and hygienic.

[0016] In the above fly larva hatching and breeding system, the conveying and transferring device is located in the fly supplement room. The fly supplement room also has a third door communicating with the breeding room. One section of the egg-laying conveying line enters the fly supplement room from the first door and then returns to the breeding fly room from the second door. One section of the breeding conveying line enters the fly supplement room from the third door and then returns to the breeding room from the third door.

[0017] Since the fly house is full of flies, a supplementary fly house is set up, and the conveying and transferring device is arranged in the supplementary fly house, so that the egg-laying conveying line and the breeding conveying line both pass through the supplementary fly house to convey the accommodation trays to the conveying and transferring device. In this way, the conveying and transferring device is not easily interfered by flies during the working process, which can improve the stability and reliability of the operation of the conveying and transferring device. At the same time, it is also convenient for the staff to carry out the daily operation and maintenance of the conveying and transferring device in the supplementary fly house.

[0018] In the above fly larva hatching and breeding system, the egg-laying conveying line is close to the wall of the fly house and is arranged along the wall of the fly house. Since flies usually tend to lay eggs in the corners or edges, the egg-laying conveying line arranged against the wall can make the most of the habit of flies laying eggs, improve the collection efficiency of fly eggs, and thus improve the breeding efficiency.

[0019] In the above fly larva hatching and breeding system, the breeding conveying line is arranged to extend circuitously in the breeding house, and the number of accommodation trays on the breeding conveying line is at least twice the number of accommodation trays on the egg-laying conveying line.

[0020] The breeding conveying line is arranged to extend circuitously in the breeding house, so that more accommodation trays can be set in the breeding house, achieving the purpose of saving space. Preferably, the number of accommodation trays on the breeding conveying line is twice the number of accommodation trays on the egg-laying conveying line. In this way, at least half of the accommodation trays on the breeding conveying line can be emptied for exchanging with the accommodation trays on the egg-laying conveying line. When the accommodation trays on the egg-laying conveying line are all filled with fly eggs, there are always sufficient accommodation trays on the breeding conveying line to exchange with all the accommodation trays on the egg-laying conveying line. In this way, the equipment has a higher breeding efficiency.

[0021] In the above fly larva hatching and breeding system, the breeding conveying line is connected end to end at the conveying and transferring device, and a dumping station is also provided in the breeding house. The dumping station is correspondingly arranged at the middle position in the length direction between the head end and the tail end of the breeding conveying line.

[0022] A dumping robot is provided at the dumping station. The dumping robot can pour out all the materials in the accommodation tray to the next process, and then put the empty tray back on the breeding conveying line again. Of course, manual dumping can also be used at the dumping station. The dumping station is correspondingly arranged at the middle position in the length direction between the head end and the tail end of the breeding conveying line, so that a breeding area and an empty area are formed in the breeding house. Half of the number of accommodation trays are located in the breeding area for hatching larvae, and the other half of the number of accommodation trays are empty trays and are located in the empty area. And the number of empty trays in the empty area is not less than the total number of accommodation trays on the egg-laying conveying line. In this way, there are always sufficient empty trays on the breeding conveying line to exchange with all the accommodation trays on the egg-laying conveying line.

[0023] In the above fly larva hatching and breeding system, a cleaning station is provided in the fly supplement room. The fly supplement room also has a fourth door and a fifth door communicating with the breeding room. The breeding conveyor line enters the fly supplement room through the fourth door after passing through the dumping station and then returns to the breeding room through the fifth door. The cleaning station is used to clean the accommodation trays on the breeding conveyor line entering the fly supplement room through the fourth door.

[0024] The cleaning station can achieve the cleaning of the accommodation trays through cleaning equipment such as cleaning nozzles or cleaning pools. Of course, manual cleaning can also be adopted. Cleaning the accommodation trays through the cleaning station can avoid the adverse effects of residual impurities and pollutants in the accommodation trays on the subsequent egg-laying process, and improve the efficiency and quality of egg-laying. Since the breeding room needs to hatch larvae, the corresponding temperature is relatively high, the smell is relatively stinky, and the sanitary conditions are relatively poor. Therefore, setting the cleaning station in the fly supplement room is convenient for cleaning the accommodation trays and is conducive to the daily operation and maintenance of the cleaning equipment by the staff.

[0025] In the above fly larva hatching and breeding system, fly-proof curtains are provided at both the first door and the second door. When the staff needs to enter the fly supplement room for work such as feeding, adding pupae, operating and maintaining equipment, setting the fly-proof curtains can block the flies in the fly breeding room from flying into the fly supplement room, thus ensuring that the fly supplement room is not easily disturbed by flies and improving the sanitary conditions of the fly supplement room.

[0026] In the above fly larva hatching and breeding system, a feeding station for adding egg-laying materials into the accommodation trays is also provided in the fly supplement room. After the breeding conveyor line enters the fly supplement room through the third door and passes through the feeding station, the accommodation trays are then transported to the conveying and transferring device. The feeding station lays a layer of egg-laying materials at the bottom of the accommodation trays. The egg-laying materials such as wheat bran are added with an appropriate amount of water, which can attract flies to lay eggs in the accommodation trays and improve the egg-laying efficiency. Since the fly supplement room is not easily disturbed by flies and has good sanitary conditions, setting the feeding station in the fly supplement room is convenient for the feeding process.

[0027] Compared with the prior art, the present fly larva hatching and breeding system has the following advantages:

[0028] 1. Both the egg-laying conveyor line and the breeding conveyor line adopt a structure with the head and tail connected. The accommodation trays continuously move along a closed loop on the egg-laying conveyor line and the breeding conveyor line, enabling the system to achieve continuous egg-laying operations, breeding operations, and accommodation tray transfer operations, thereby improving the automation level and breeding efficiency of the system and enabling the system to achieve large-scale production.

[0029] 2. Through the cooperation of the egg-laying conveyor line, the breeding conveyor line, and the conveying and transferring device, and by combining the ratio of the accommodation trays on the breeding conveyor line and the number of accommodation trays on the egg-laying conveyor line, the automated degree and breeding efficiency of the fly larva hatching and breeding system can be greatly improved, enabling the system to meet the requirements of large-scale production.

[0036] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to this embodiment.

[0037] As Figure 1As shown in the figure, this fly larva hatching and breeding system includes a fly breeding room 1, a breeding room 2 and a fly supplement room 7. Inside the fly breeding room 1, there is an egg-laying conveyor line 3 that is connected end to end. The egg-laying conveyor line 3 is close to the wall of the fly breeding room 1 and is arranged along the wall of the fly breeding room 1. Inside the breeding room 2, there is a breeding conveyor line 4 that is connected end to end. On both the egg-laying conveyor line 3 and the breeding conveyor line 4, there are accommodation trays 5. The breeding conveyor line 4 extends circuitously inside the breeding room 2. The number of accommodation trays 5 on the breeding conveyor line 4 is more than the number of accommodation trays 5 on the egg-laying conveyor line 3. In this implementation, the number of accommodation trays 5 on the egg-laying conveyor line 3 is 600, and the number of accommodation trays 5 on the breeding conveyor line 4 is 1200. During the actual production process, the number of accommodation trays 5 can be adjusted according to the production scale. Generally, the number of accommodation trays 5 on the breeding conveyor line 4 is at least twice that of the accommodation trays 5 on the egg-laying conveyor line 3.

[0038] As Figure 1 and Figure 2 shown in the figure, this fly larva hatching and breeding system also includes a conveying and transferring device 6. Both the egg-laying conveyor line 3 and the breeding conveyor line 4 can convey their respective accommodation trays 5 to the conveying and transferring device 6. The conveying and transferring device 6 includes a first manipulator 61 and a second manipulator 62 that can reciprocate between the egg-laying conveyor line 3 and the breeding conveyor line 4. The first manipulator 61 can transfer the accommodation tray 5 on the egg-laying conveyor line 3 to the breeding conveyor line 4 through its own movement, and the second manipulator 62 can transfer the accommodation tray 5 on the breeding conveyor line 4 to the egg-laying conveyor line 3 through its own movement.

[0039] As Figure 1 and Figure 2 shown in the figure, the fly supplement room 7 has a first door 8 and a second door 9 that are both connected to the fly breeding room 1. Inside the fly breeding room 1, there is a fly supplement conveyor line 10. On the fly supplement conveyor line 10, there is a fly supplement tray 11 that can move along its conveying direction. One section of the fly supplement conveyor line 10 enters the fly supplement room 7 through the first door 8 and then returns to the fly breeding room 1 through the second door 9. The flies in the fly breeding room 1 will die continuously. By setting up the fly supplement conveyor line 10 so that it passes through the fly supplement room 7, the staff can supplement the pupae of flies in the fly supplement tray 11, and then rely on the fly supplement conveyor line 10 to supplement the pupae into the fly breeding room 1. The pupae hatch into flies in the fly breeding room 1, thus ensuring that the number of flies in the fly breeding room 1 meets the requirements.

[0040] As Figure 1 and Figure 2As shown, the conveying and transferring device 6 is located in the fly supplement room 7. The fly supplement room 7 also has a third door 12 communicating with the breeding room 2. One section of the egg-laying conveying line 3 enters the fly supplement room 7 through the first door 8 and then returns to the breeding fly room 1 through the second door 9. One section of the breeding conveying line 4 enters the fly supplement room 7 through the third door 12 and then returns to the breeding room 2 through the third door 12. Fly-proof curtains 17 are provided at both the first door 8 and the second door 9. By setting the fly-proof curtains 17, flies in the breeding fly room 1 can be blocked from flying into the fly supplement room 7, thus ensuring that the fly supplement room 7 is not easily disturbed by flies and improving the sanitation conditions of the fly supplement room 7.

[0041] As Figure 1 and Figure 2 shown, the breeding conveying line 4 is connected end to end at the conveying and transferring device 6. A dumping station 13 is also provided in the breeding room 2, and the dumping station 13 is correspondingly arranged at the middle position in the length direction between the head end and the tail end of the breeding conveying line 4. A dumping robot is provided at the dumping station 13. The dumping robot can pour out all the materials in the accommodation tray 5 to the next process, and then put the empty tray back onto the breeding conveying line 4 again. Of course, manual dumping can also be used at the dumping station 13. A cleaning station 16 is provided in the fly supplement room 7. The fly supplement room 7 also has a fourth door 14 and a fifth door 15 communicating with the breeding room 2. After passing through the dumping station 13, the breeding conveying line 4 enters the fly supplement room 7 through the fourth door 14 and then returns to the breeding room 2 through the fifth door 15. The cleaning station 16 is used to clean the accommodation tray 5 on the breeding conveying line 4 that enters the fly supplement room 7 through the fourth door 14. The cleaning station 16 can use cleaning equipment such as cleaning nozzles or cleaning pools to clean the accommodation tray 5. Of course, manual cleaning can also be used. By cleaning the accommodation tray 5 at the cleaning station 16, the adverse effects of residual impurities and pollutants in the accommodation tray 5 on the subsequent egg-laying process can be avoided, and the efficiency and quality of egg-laying can be improved.

[0042] As Figure 1 and Figure 2 shown, a feeding station 18 for adding egg-laying materials into the accommodation tray 5 is also provided in the fly supplement room 7. After the breeding conveying line 4 enters the fly supplement room 7 through the third door 12 and passes through the feeding station 18, the accommodation tray 5 is then conveyed to the conveying and transferring device 6. The feeding station 18 lays a layer of egg-laying materials at the bottom of the accommodation tray 5. The egg-laying materials such as wheat bran are added with an appropriate amount of water, which can attract flies to lay eggs in the accommodation tray 5 and improve the egg-laying efficiency.

[0043] The working principle of this fly larva hatching and breeding system is as follows: First, the fly house 1 is filled with flies. The flies lay eggs in the accommodation trays 5 on the egg-laying conveyor line 3. After the egg-laying is completed, the egg-laying conveyor line 3 sequentially transports the accommodation trays 5 to the conveying and transferring device 6. The conveying and transferring device 6 sequentially transfers all the accommodation trays 5 on the egg-laying conveyor line 3 to the breeding conveyor line 4, and at the same time transfers an equal number of accommodation trays 5 from the breeding conveyor line 4 to the egg-laying conveyor line 3.

[0044] The accommodation trays 5 with collected eggs are hatched and bred on the breeding conveyor line 4. After the eggs hatch into larvae, the breeding conveyor line 4 sequentially transports the accommodation trays 5 to the dumping station 13. The dumping station 13 dumps the materials with larvae in the accommodation trays 5, collects and utilizes the larvae, forming empty accommodation trays 5. After being cleaned by the cleaning station 16, the empty accommodation trays 5 are transported to the feeding station 18. The feeding station 18 lays egg-laying materials suitable for flies to lay eggs in the accommodation trays 5. The egg-laying materials such as wheat bran are added with an appropriate amount of water. After the eggs in the accommodation trays 5 on the egg-laying conveyor line 3 are completed, the exchange of the accommodation trays 5 is carried out again, and so on in a cycle.

[0045] Among them, the conveying and transferring device 6 is as Figures 3 to 5 shown. The egg-laying conveyor line 3 and the breeding conveyor line 4 are parallel to each other and have opposite conveying directions at the conveying and transferring device 6. Figures 3 to 5 In, the direction indicated by the straight arrow is the conveying direction of the egg-laying conveyor line 3 or the breeding conveyor line 4. The moving directions of the first manipulator 61 and the second manipulator 62 of the conveying and transferring device 6 are perpendicular to the conveying direction of the egg-laying conveyor line 3 at the conveying and transferring device 6. In actual situations, hanging brackets are arranged along the conveying directions of the egg-laying conveyor line 3 and the breeding conveyor line 4, and the accommodation trays 5 are placed on the hanging brackets. At this time, the first manipulator 61 and the second manipulator 62 transfer the accommodation trays 5 by grasping the hanging brackets. Of course, the first manipulator 61 and the second manipulator 62 can also directly grasp the accommodation trays 5 to achieve the transfer of the accommodation trays 5.

[0046] When the conveying and transferring device 6 is working, as Figure 3 , the first manipulator 61 and the second manipulator 62 respectively grab a group of accommodation trays 5 from the egg-laying conveyor line 3 and the breeding conveyor line 4. At this time, a vacancy is respectively formed on the egg-laying conveyor line 3 and the breeding conveyor line 4. And because the conveying directions of the egg-laying conveyor line 3 and the breeding conveyor line 4 are opposite at the conveying and transferring device 6, after the egg-laying conveyor line 3 and the breeding conveyor line 4 respectively run one stroke, as Figure 4 shown, it can make the vacancy on the egg-laying conveyor line 3 face the second manipulator 62, and at the same time the vacancy on the breeding conveyor line 4 faces the first manipulator 61. After that, as Figure 5As shown, the first manipulator 61 transfers the container tray 5 with fly eggs to the empty space on the breeding conveyor line 4, while the second manipulator 62 transfers the container tray 5 with egg-receiving materials to the empty space on the egg-receiving conveyor line 3. In this way, an exchange transfer of the container tray 5 is completed. This cycle continues until the mutual exchange of all the container trays 5 on the egg-receiving conveyor line 3 and an equal number of container trays 5 on the breeding conveyor line 4 is completed.

Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar ways for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
