Description

Technical Field

[0001] This utility model belongs to the field of plastic film perforation technology, specifically relating to a perforation device for morel mushroom plastic film. Background Technology

[0002] In recent years, as the edible, medicinal, and health benefits of morel mushrooms have gained increasing recognition, their cultivation scale has continued to expand. With yields gradually stabilizing, in order to further improve the yield and quality of morel mushrooms and obtain greater economic benefits, morel mushroom cultivation and management techniques have become increasingly refined. It has been found that covering the seedbed with a layer of black mulch after sowing morel mushrooms can effectively retain heat, moisturize, prevent waterlogging, provide shade, inhibit weed growth, control excessive "frost" (a type of fungal bloom), and promote fruiting later. However, as morel mushrooms are aerobic fungi, covering them with mulch can lead to insufficient oxygen for the mycelium in the soil during growth, affecting the mycelial growth process and resulting in lower yields and more deformed mushrooms, significantly impacting both the quantity and quality of morel mushrooms. To change this situation, when covering morel mushrooms with plastic film, people make holes in the film at regular intervals to ensure that the film covers the seedbed without affecting ventilation. This provides sufficient oxygen for the morel mushrooms to grow, allowing them to accumulate nutrients and laying the foundation for improved yield and quality in the later stages.

[0003] Current technologies mostly employ manual drilling, using pointed bamboo skewers, wooden sticks, or cones to pierce the mulch film; or using a simple semi-mechanical drilling method, where one or more rows of cones (bamboo skewers, metal nails, etc.) are pre-fixed on wooden boards, strips, or lightweight metal frames according to predetermined row and plant spacing. These can be made into single or multiple rows of rollers (similar to rakes) or flat pressing mechanisms. By stepping on, pressing, or rolling, the cones on the frame simultaneously pierce the covering soil. Manual drilling is inefficient, and ordinary semi-mechanical drilling is easily affected by ground unevenness, resulting in poor drilling effects. Furthermore, both of these methods directly disturb the mycelium on the surface of the mulch film, affecting the formation of morel "frost" (conidia). Deep insertion can also severely damage the morel mycelium beneath the mulch film, preventing its normal growth. If the drilling tools are not strictly sterilized, insertion into the mulch film may lead to contamination by exogenous bacteria, causing reduced yield and deformed mushrooms later on. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a special perforation device for morel mulch film, which addresses the shortcomings of existing technologies that cause significant disturbance to morel mycelia and may damage the mycelium.

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] A perforation device for morel mushroom mulch film includes a perforation carriage 1 and a perforation assembly 2. The perforation carriage 1 includes a fixed plate 11 and wheels 12. The perforation assembly 2 is fixedly mounted on the fixed plate 11. The perforation assembly 2 includes a battery 21, a microcontroller 22, an electric heating head 23, an electric push rod 24, and a negative pressure air pump 25. The electric push rod 24 is fixedly mounted on the fixed plate 11, and its power output end passes through the fixed plate 11 and is detachably connected to the electric heating head 23. The electric heating head 23 and the... The electric push rod 24 is equipped with baffles 26 on all sides, and a negative pressure air pump 25 is provided on the top of the baffles 26 outside the electric push rod 24; the length of the baffles 26 outside the electric heating mold head 23 is greater than the length of the electric heating mold head 23, and several ventilation holes 27 are provided through the fixing plate 11 inside the baffles 26; the battery 21 is electrically connected to the microcontroller 22, the electric heating mold head 23, the electric push rod 24 and the negative pressure air pump 25; the microcontroller 22 is electrically connected to the electric push rod 24 to control the extension and retraction of the electric push rod 24.

[0024] Under the mulch, the morel mushrooms grow in a relatively enclosed environment. To effectively prevent oxygen deficiency, the mulch is raised at intervals to allow for ventilation. Therefore, the morel mulch is relatively uneven. The negative pressure generated by the negative pressure pump 25 of this device causes the morel mulch to float upwards, near the bottom of the perforation assembly 2. The electric push rod 24 then drives the pre-heated electric heating head 23 to extend beyond the protection of the cover 26, scalding the mulch before retracting, thus completing the perforation process with minimal impact on the morel mycelium beneath. Under the action of the negative pressure pump, the air around the perforated mulch flows rapidly, carrying away heat and causing the perforated area to cool and solidify quickly, resulting in a neatly sealed hole. The holes are uniform in size, preventing further tearing and making the operation more standardized.

[0025] Furthermore, the electric heating head 23 includes a head shell 231 and an electric heating tube 232; the electric heating tube 232 is disposed inside the head shell 231 and electrically connected to the battery 21 via a microcontroller 22; a temperature sensor 233 is also disposed inside the head shell 231; the temperature sensor 233 is electrically connected to the microcontroller 22. The exterior of the head shell 231 is coated with a Teflon non-stick coating. The Teflon non-stick coating makes it difficult for the high-temperature molten mulch film to adhere to the surface of the electric heating head 23.

[0026] Furthermore, on one side of the fixing plate 11 near the wheel 12, a first support rod 13 extending obliquely upwards is provided, the projection of the first support rod 13 on the fixing plate 11 being parallel to the direction of movement of the punching trolley 1; on the other side of the fixing plate 11 near the wheel 12, a second support rod 14 extending obliquely upwards towards the first support rod 13 is provided; a ring handle 15 is fixedly connected to the end of the first support rod 13 and the second support rod 14 away from the fixing plate 11. A control switch 16 is provided on the ring handle 15; the control switch 16 includes an air pump switch 161, a die head heating switch 162, and a trigger switch 163; the trigger switch 163 is a self-resetting spring-loaded trigger switch; the control switch 16 is electrically connected to the microcontroller 22. The off-design ring handle 15 near the fixing plate 11 is more in line with the operating characteristics, allowing operators to move along the furrows and making it easier to operate the device.

[0027] Furthermore, side ear fixing plates 111 extend downward on both sides of the fixing plate 11; at least two through holes 112 are provided on the side ear fixing plates 111; an adjusting plate 121 is provided on the side of the wheel 12 near the fixing plate 11 and is rotatably connected to the wheel 12; a plurality of connecting holes 122 corresponding to the through holes 112 are provided on the adjusting plate 121; the adjusting plate 121 and the side ear fixing plates 111 are fixedly connected by bolts through the corresponding through holes 112 and connecting holes 122.

[0028] Furthermore, the fixing plate 11 extends and is fixedly connected to a limiting clamp 113 on the side opposite to the direction of movement of the punching trolley 1; the limiting clamp 113 is connected to a telescopic indicator rod 17 in the middle with damping rotation.

[0029] Push the device to the head of the morel mushroom planting bed that has been covered with film. First, according to the position of the bed height adjustment bolt passing through the through hole 112 on the side ear fixing plate 111 and the corresponding connection hole 122 on the adjustment plate 121, quickly change the height of the wheel relative to the fixing plate so that the electric heating head and the film plane maintain a relative working gap. Then, pull the telescopic indicator rod 17 out from the limiting clamp plate 113 to extend the distance required for drilling. When the drilling trolley is moving, the operator can refer to the telescopic indicator rod 17 to ensure that the entire row of holes is parallel to the edge of the bed and the row spacing is stable. The operator holds the ring handle 15, allowing their fingers to naturally rest on the self-resetting spring-loaded trigger switch 163. After pressing the mold head heating switch 162, the battery 21 supplies power to the electric heating tube 232. The temperature sensor 233 inside the mold head housing 231 feeds back the real-time value to the microcontroller 22. The microcontroller 22 uses an algorithm to control the electric heating mold head to maintain a temperature of 200 ℃ ± 10℃. Then, pressing the air pump switch 161 activates the negative pressure air pump 25, which creates a continuous negative pressure chamber inside the baffle through the vent 27. During operation, the negative pressure created by the negative pressure air pump 25 causes the morel mushroom mulch to float upwards, approaching the bottom of the perforation assembly 2. Each time the operator presses the self-resetting trigger switch 163, the microcontroller 22 immediately outputs a pulse signal to drive the electric push rod 24 downwards. The electric heating mold head 23 instantly pierces the mulch and burns a smooth round hole. After a fixed interval, the microcontroller 22 outputs another pulse signal, and the electric push rod 24 resets and retracts, completing one perforation operation.

[0030] Through the aforementioned continuous operation, the device improves drilling efficiency while controlling the errors in hole diameter, spacing, and depth within quantitative limits. This provides a uniform environment for ventilation, light transmission, and moisture retention during the later stages of morel mushroom growth, without directly disturbing the mycelium on the surface of the planting bed. By not inserting the device into the planting bed, it avoids damaging the underlying mycelium, reducing the chance of infection. Furthermore, the machine is highly adaptable to various terrains, easy to maintain, and can be seamlessly extended to high-density cultivation scenarios for other mulched crops such as strawberries and tomatoes.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
