Description

Technical Field

[0001] The utility model relates to the technical field of factory-based bat moth larvae breeding, in particular to a device for automatically counting the hatching rate of bat moth eggs. Background Art

[0002] The larvae of the bat moth are the host insects of Cordyceps sinensis. They belong to the family of the Lepidoptera order. They are mainly distributed in alpine meadows above 3,000 meters above sea level on the Qinghai-Tibet Plateau. In my country, they are mainly concentrated in five provinces and regions, including Tibet, Sichuan, Gansu, Qinghai, and Yunnan. It takes 3-5 years to complete a generation in the wild, and there is alternation of generations. They mainly feed on the roots of plants such as the Lycopodiaceae and the Gramineae. In recent years, they have been able to be raised indoors on a large scale, and the time it takes to complete a generation has been shortened to 1 year. Since the larvae of the bat moth are soil-dwelling insects, their hatching is mainly in the matrix. If they are transferred after hatching, the survival rate of the larvae will be significantly reduced. However, due to uneven hatching, the hatched larvae are small and quickly bury themselves in the soil, making it impossible to quickly count the hatching rate, which brings inconvenience to the later factory breeding production.

[0003] Bat moth eggs are small, nearly spherical, scattered eggs (similar to rapeseed, but smaller). During production, the eggs are placed in a moisturizing dish for incubation in advance. After they hatch, the larvae are counted and transferred regularly, which takes 1-3 days. The larvae crawl everywhere, which affects the accuracy of the count. At the same time, because the larvae are weak, the transfer with a brush, even if the action is gentle, will inevitably cause some damage to the larvae, resulting in a lower survival rate of the larvae. If the larvae are hatched out of the breeding environment, they will not be able to eat in time, which affects the survival rate.

[0004] (1) Manual counting has high labor costs and can easily cause certain damage to the larvae, affecting the survival rate;

[0005] (2) Because there is no significant difference in appearance between the hatching rate and the unhatched rate, it is difficult to distinguish them when counting;

[0006] (3) The statistical process is slow and cannot be counted automatically;

[0007] Therefore, there is an urgent need for a device for automatically counting the hatching rate of bat moth eggs to replace manual counting without affecting the hatching activity of the larvae. Summary of the invention

[0008] In order to solve the problem of inconvenience in the existing statistics of bat moth hatching rate, the utility model proposes a device for automatically counting the hatching rate of bat moth eggs, which includes a hatching plate, a laser emitting plate arranged at the upper end of the hatching plate, and a light-sensing receiving plate at the lower end. Since the hatched larvae crawl onto the substrate, the output electrical signal of the light-sensing receiving plate changes, and the hatching counting is realized in combination with an MCU chip, and displayed on a display screen.

[0009] A device for automatically counting the hatching rate of bat moth eggs, comprising a hatching plate, a plurality of hatching holes arranged in a square array, bat moth eggs placed in the hatching holes, a laser emitting plate arranged at the upper end of the hatching plate, a photosensitive receiving plate arranged at the lower end of the hatching plate, the laser emitting plate comprising a plurality of laser emitters, the plurality of laser emitters being arranged in a square array corresponding to the hatching holes, the photosensitive receiving plate comprising a plurality of photosensitive receivers, the plurality of photosensitive receivers being arranged in a square array corresponding to the hatching holes, and the number of the laser emitters, the hatching holes and the photosensitive receivers corresponding to each other.

[0010] The output end of the light-sensing receiver is connected to an MCU chip, the MCU chip is communicatively connected to a display screen, and the output end of the MCU chip is connected to a plurality of laser transmitters.

[0011] The hatching hole is a through hole. When bat moth eggs are placed in the hatching hole, the laser emitted by the laser transmitter set at the upper end of the hatching plate is blocked by the bat moth eggs, and the light-sensing receiver cannot receive the laser and outputs a low-level signal. Since the hatched larvae will crawl into the matrix to feed, the light-sensing receiver at this position can receive the laser emitted by the laser transmitter, and the light-sensing receiver outputs a high level, and the MCU chip counts.

[0012] Further, the incubation plate is a square plate, comprising a top plate and a side plate, a plurality of circular through holes are formed in a straight line array on the side wall of the side plate, and square through holes are formed at the bottom and top of the plurality of circular through holes corresponding to the circular through holes;

[0013] The round through hole and the square through hole are combined to form a hatching hole.

[0014] The hatching hole is roughly a U-shaped structure with a broken lower end, which can hold insect eggs and facilitate the passage of laser.

[0015] Preferably, a plurality of square holes are provided on the top plate corresponding to the hatching holes, the square holes are in a straight line, and the plurality of square holes are arranged in a straight line along the side of the top plate corresponding to the hatching holes.

[0016] The straight groove is provided to facilitate the larvae to crawl out of the hatching plate and enter the matrix to feed.

[0017] Furthermore, the incubation plate is fixedly connected to the top plate.

[0018] Furthermore, the plurality of laser emitters are provided with a driver chip, the laser emitters are connected to a power source via the driver chip, and an input end of the driver chip is connected to an IO pin of the MCU chip.

[0019] Furthermore, the MCU chip is connected to the display screen via UART serial port communication.

[0020] Through the above technical solution, the beneficial effects of the utility model are:

[0021] The utility model can count the hatching amount and provide a hardware basis for calculating the hatching rate of bat moth eggs without transferring bat moth eggs. A hatching plate is set, and bat moth eggs are placed in the hatching hole. The hatching plate is set on the surface of the larval feeding environment. After the larvae are hatched, they crawl into the matrix and feed, which reduces the transfer damage of the larvae, provides a feeding environment in time, and effectively improves the survival rate of the larvae. After waiting for the larval hatching period to end, the hatching plate is taken out, a laser transmitting plate is set on the upper part of the hatching plate, and a light receiving plate is set on the lower part of the hatching plate. Since the larvae hatch and crawl out of the hatching plate, the hatching hole is empty, so the light receiving receiver can receive the laser signal output by the laser transmitter, and the light receiving receiver outputs a high-level signal, and the MCU chip counts.

DETAILED DESCRIPTION

[0031] The output end of the light-sensing receiver 6 is connected to an MCU chip 7 , and the MCU chip 7 is communicatively connected to a display screen 8 . The output end of the MCU chip 7 is connected to a plurality of laser transmitters 5 .

[0032] Preferably, the incubation plate 1 is a square plate, and the incubation plate 1 comprises a top plate 101 and a side plate 102, a plurality of circular through holes 9 are formed in a straight line array on the side wall of the side plate 102, and square through holes 10 are formed at the bottom and the top of the plurality of circular through holes 9 corresponding to the circular through holes 9;

[0033] The circular through hole 9 and the square through hole 10 are combined to form the hatching hole 2 .

[0034] Preferably, a plurality of square holes 11 are provided on the top plate 101 corresponding to the hatching holes 2 , the square holes 11 are in a straight line, and the plurality of square holes 11 are arranged in a straight line along the side of the top plate 101 corresponding to the hatching holes 2 .

[0035] Preferably, the side plate 102 is fixedly connected to the top plate 101. The top plate 101 is a plate-like structure made of a hard material wrapped with silica gel.

[0036] Preferably, the plurality of laser emitters 5 are provided with a driver chip 12 , the laser emitters 5 are connected to a power source via the driver chip 12 , and an input end of the driver chip 12 is connected to an IO pin of the MCU chip 7 .

[0037] The MCU chip 7 is an STM32 single-chip microcomputer, the driver chip 12 uses a MOS tube driver chip, and the laser transmitter 5 and the light receiver 6 use a beam-type photoelectric switch.

[0038] Preferably, the MCU chip 7 is connected to the display screen 8 via UART serial port communication.

[0039] In order to facilitate input of instructions, the IO interface of the MCU chip 7 is connected with a key.

[0040] Before operation, the hatching plate 1 is set on the substrate, and bat moth eggs are set in each hatching hole 2. The bat moth eggs are in the larval breeding environment, and the bat moth eggs will hatch within 1-3 days. The hatched larvae will crawl from the hatching hole to the substrate to feed. Reduce the transfer damage of larvae, provide a feeding environment in time, and effectively improve the survival rate of larvae.

[0041] After the larvae hatch, some larvae can take the egg shell away, and some egg shells will remain inside the hatching hole. At this time, the egg shell is hollow. Compared with the bat moth eggs that fail to hatch larvae, the laser can pass through the hollow egg shell and project onto the light-sensing receiver 6.

[0042] After three days, the incubation plate 1 is taken out and the surface moisture is dried. A laser emitting plate 3 is set on the upper part of the incubation plate 1 and a light receiving plate 4 is set on the lower part of the incubation plate 1. The MCU chip 7 is powered on by pressing a button. The MCU chip 7 powers on multiple laser emitters 5 synchronously through the driving chip 12, and the multiple laser emitters 5 emit lasers at the same time.

[0043] The laser passes through the square hole 11 downward and enters the hatching hole 2. If there are eggs that have not hatched larvae in the hatching hole 2, the laser is blocked, and the corresponding light-sensing receiver 6 does not receive the laser and outputs a low-level signal. After the eggs in the hatching hole 2 are successfully hatched, the bottom of the hatching hole 2 is a through hole, and the laser passes through the hatching hole 2 and irradiates the light-sensing receiver 6. The light-sensing receiver 6 outputs a high-level signal, and the MCU chip 7 receives the high-level signal and counts.

[0044] Since the number of eggs placed is known, the hatching rate is calculated after the number of hatched eggs is obtained. The MCU chip 7 calculates the hatching rate and then displays it on the display screen 8.

[0045] Finally, a reset signal is sent to the MCU chip 7 by pressing a button, and the MCU chip 7 uses the driving chip 12 to synchronously power off the multiple laser emitters 5, and the operation is completed.

Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
