Description

Technical Field

[0001] This invention relates to the field of agriculture, and more particularly to a crop cultivation device. Background Technology

[0002] Fermentation substrate cultivation involves mixing various raw materials evenly, piling them into heaps according to specific standards, and allowing them to undergo a fermentation process over a period of time. Once the temperature inside the heap reaches the required level, the heap needs to be turned 3 to 5 times. Subsequently, inoculation is carried out under natural conditions, and mycelial growth and fruiting body (mushroom) formation are promoted in a suitable temperature and humidity environment. This method is suitable for all edible fungi species that can be cultivated using raw materials, especially various species of the *Agaricus* genus, such as *Agaricus bisporus*, *Agaricus macrocarpa*, and *Agaricus blazei*. In addition, straw mushrooms, oyster mushrooms, and *Coprinus comatus* are also commonly cultivated using this method.

[0003] In the inoculation process, the spawn is usually broken into pieces the size of dates to walnuts and inoculated manually. Several points need to be noted in this practice: First, the inoculation depth must be appropriate. Too deep, and the mycelium may have difficulty penetrating the covering or promote lateral development of the mycelium. Too shallow, and the mycelium growth may be affected due to insufficient nutrients. Second, although electric inoculation tools are convenient to operate, their high cost and the physical damage they may cause to the mycelial clump (such as when dragged by a cable) limit their application. Finally, the opening size of the plastic film must be properly controlled when manually inoculating. An opening that is too large will not only cause heat loss and leakage of fermentation material, but also increase the risk of bacterial invasion. An opening that is too small will make it difficult for the mycelium to penetrate the film. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a crop cultivation device that manually achieves fixed-depth and quantitative feeding and inoculation functions. It is easy to use by hand, reducing operational burden. The entire process requires no electricity, relying solely on human power, making it economical and highly effective. The fixed opening size of its plastic film ensures a suitable growth environment for the bacterial strains, thus improving growth outcomes.

[0005] The technical solution adopted in this invention is: a crop cultivation device, including a movable clamping plate and a fixed clamping plate, wherein the two sides near the front end of the movable clamping plate and the fixed clamping plate are connected by two pairs of hinge plates symmetrically arranged on both sides of the device, and the two pairs of hinge plates are hinged by a hinge shaft.

[0006] A U-shaped clamp is fixed inside the fixed clamping plate, and a detachable clamping device is used to hold the injection cylinder inside the U-shaped clamp. The front end of the injection cylinder is provided with a narrowing structure.

[0007] A push rod is slidably fitted coaxially inside the injection cylinder. A push head is fixed at the top of the push rod and seals against the inner wall of the injection cylinder. Notches that are evenly distributed along the axial direction on the surface of the push rod are inclined towards the discharge port of the injection cylinder.

[0008] A spring is fixed inside the movable clamping plate. The spring is inclined toward the discharge end of the injection cylinder, and the thickness of its free end is less than the width of the notch so as to embed into the notch to achieve a one-way snap-fit ​​structure.

[0009] Both the movable and fixed clamps have inwardly inclined sharp structures at their front ends, forming a piercing structure when closed. When the device's front end penetrates the plastic film, it creates a small insertion hole, reducing yeast leakage and effectively preventing bacterial invasion while ensuring the hole size is appropriate to avoid hindering bacterial penetration. Furthermore, once the plastic film is pierced, the wider portions of the movable and fixed clamps stop penetrating further due to the film's obstruction, thus achieving precise control of the planting depth.

[0010] Working principle:

[0011] During inoculation, hold the movable and fixed clamps by hand and use their tips to penetrate the plastic film and insert them into the fermentation medium. By squeezing, the movable clamp is brought closer to the fixed clamp, creating an injection gap at the front ends of both clamps. At this point, the end of the spring engages with the corresponding notch. Because the notch is inclined towards the discharge port of the injection cylinder, this prevents the spring from slipping out of the notch and disengaging. Simultaneously, when the movable clamp resets, the spring will not cause the push rod to retract. Since the spring is elastic but has a constant length, when the movable clamp is continuously pressed down, the elastic potential energy of the spring is converted into a pushing force on the push rod, thereby driving the push rod to perform axial feeding motion, achieving precise injection of the inoculum solution. After inoculation, the device is vertically extracted and the pressure on the movable clamp is released. At this point, the spring automatically disengages from the notch due to its elastic reset, preparing for subsequent inoculation operations. The entire cycle effectively ensures inoculation accuracy and operational efficiency.

[0012] Preferably, the hinge shaft of the hinge plate is provided with a torsion spring, which drives the movable clamping plate and the fixed clamping plate to automatically reset to the closed state, so that the spring disengages from the notch, so that the spring can engage with other notches to push the push rod.

[0013] Preferably, the inner side of the U-shaped clamp is provided with a fixing groove, and the outer wall of the injection cylinder is provided with a positioning protrusion that can be embedded in the fixing groove at a corresponding position. The cooperation between the fixing groove and the positioning protrusion is used to stabilize the position of the injection cylinder, ensuring that the pushing of the push rod during inoculation will not cause the injection cylinder to shift. If it is necessary to change the inoculum in the injection cylinder, simply operate the U-shaped clamp to loosen it, and the injection cylinder can be easily removed for internal cleaning and replacement with new inoculum.

[0014] Preferably, the fixed clamping plate has a nut seat vertically positioned at its tail end, and the nut seat is internally threaded with an adjusting bolt for adjusting the clamping distance. When the movable clamping plate is pressed down, its tail end encounters the obstruction of the adjusting bolt, thereby limiting the rotation angle of the movable clamping plate. By rotating the adjusting bolt, the stroke of the spring is adjusted, thereby controlling the stroke of the push rod, ultimately achieving precise control of the output amount.

[0015] Preferably, a dispensing needle is fixed to the front end of both the movable and fixed clamps. The dispensing needle pierces the fermentation substrate when the clamps are closed and moves the surrounding substrate to cover the injection hole when the clamps are reset. During inoculation, the dispensing needle first pierces the adjacent fermentation substrate. After the inoculum is injected, the dispensing needle moves to the surrounding fermentation substrate by rotating the movable and fixed clamps. Subsequently, the movable clamps reset, causing the dispensing needle to agitate the fermentation substrate to cover the inoculum. Because the fermentation substrate contains abundant fiber, it is easily agitated by the dispensing needle. When the dispensing needle is initially inserted, the surrounding material is gently moved aside along with the movement of the movable clamps; therefore, the dispensing needle needs to be rotated to a new material position to continue the operation.

[0016] Preferably, the push rod is provided with a pull plate at its end. By pulling the pull plate, the push rod is moved backward to draw the inoculum into the injection cylinder under negative pressure, thus eliminating the need for frequent replacement of the injection cylinder.

[0017] Preferably, a slide rail is fixedly provided on the inner side of the fixed clamping plate, and a guide rod is provided on the pull plate in the opposite direction to the notch. The guide rod is slidably engaged in the slide rail. By utilizing the synergistic effect of the guide rod and the slide rail, the orientation of the notch can be determined, thereby ensuring that the spring can always be accurately embedded into the corresponding notch.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By setting up a movable clamp, a fixed clamp, and a spring, the spring, due to its elasticity but constant length, converts the elastic potential energy of the spring into a pushing force on the push rod when the movable clamp is continuously pressed down. This drives the push rod to perform axial feeding motion, achieving precise injection of the inoculum solution. After inoculation, the device is vertically extracted and the pressure on the movable clamp is released. At this time, the spring automatically disengages from the notch due to elastic reset, preparing for subsequent inoculation operations. The entire cycle effectively ensures inoculation accuracy and operational efficiency. The device is easy to hold, convenient and labor-saving to operate, purely manual, and low in cost.

[0020] 2. By using the nut and adjusting bolt assembled at the tail end of the fixed clamp, the front ends of the movable clamp and the fixed clamp form a sharp structure that tilts inward. When closed, the sharp points contact to form a puncture structure, achieving precise depth and quantitative inoculation with good inoculation effect. At the same time, the plastic film opening provides good protection for the growth of the strain. Attached Figure Description

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] like Figures 1-4 As shown, a crop cultivation device includes a movable clamping plate 1 and a fixed clamping plate 2. The two sides of the movable clamping plate 1 and the fixed clamping plate 2 near the front end are connected by two pairs of hinged plates 3 symmetrically arranged on both sides of the device, and the two pairs of hinged plates 3 are hinged by a hinge shaft.

[0029] A U-shaped clamp 4 is fixed inside the fixed clamp plate 2. The U-shaped clamp 4 holds the injection cylinder 5 in a detachable clamp. The front end of the injection cylinder 5 is provided with a narrowing structure.

[0030] Inside the injection cylinder 5, there is a push rod 6 that slides coaxially. The top of the push rod 6 is fixed with a push head 7 that seals with the inner wall of the injection cylinder 5. The surface of the push rod 6 has notches 8 that are evenly distributed along the axial direction and inclined towards the discharge port of the injection cylinder 5.

[0031] The inner side of the movable clamping plate 1 is fixed with a spring 9. The spring 9 is inclined towards the discharge end of the injection cylinder 5, and the thickness of its free end is less than the width of the notch 8 so as to embed into the notch 8 to achieve a one-way snap-fit ​​structure.

[0032] Both the movable clamp 1 and the fixed clamp 2 have inwardly inclined sharp structures at their front ends, and when closed, the sharp points contact to form a piercing structure. When the front end of the device penetrates the plastic film, it can form a small puncture hole, which reduces the leakage of fermentation material and effectively prevents bacterial invasion, while ensuring that the hole size is appropriate and does not hinder the strains from penetrating the film. In addition, once the plastic film is punctured, the wider parts of the movable clamp 1 and the fixed clamp 2 will stop penetrating further due to the obstruction of the plastic film, thereby achieving precise control of the planting depth.

[0033] Working principle:

[0034] During inoculation, the movable clamp 1 and fixed clamp 2 are held together, and their tips are used to penetrate the plastic film and pierce into the fermentation material. A pinching motion is used to bring the movable clamp 1 closer to the fixed clamp 2, at which point the front ends of the two clamps unfold to form an injection gap. At this point, the end of the spring 9 engages with the corresponding notch 8. Because the notch 8 is inclined towards the outlet of the injection cylinder 8, this prevents the spring 9 from slipping out of the notch 8 and disengaging. Simultaneously, when the movable clamp 1 resets, the spring 9 will not cause the push rod 6 to retract. Since the spring 9 is elastic but has a constant length, when the movable clamp 1 is continuously pressed down, the elastic potential energy of the spring 9 is converted into a pushing force on the push rod 6, thereby driving the push rod 6 to perform axial feeding motion, achieving precise injection of the inoculum solution. After inoculation, the vertical extraction device is activated and the pressure on the movable clamp 1 is released. At this point, the spring 9 automatically disengages from the notch 8 due to its elastic reset, preparing for subsequent inoculation operations. The entire cycle effectively ensures inoculation accuracy and operational efficiency.

[0035] The hinge plate 3 is equipped with a torsion spring on its hinge shaft, which drives the movable clamping plate 1 and the fixed clamping plate 2 to automatically return to the closed state, so that the spring 9 disengages from the notch 8, so that the spring 9 can engage with other notches 8 to push the push rod 6.

[0036] The U-shaped clamp 4 has a fixing groove 10 on its inner side, and the corresponding positioning protrusion 11 on the outer wall of the inoculation cylinder 5 can be embedded in the fixing groove 10. The fixing groove 10 and the positioning protrusion 11 are used to stabilize the position of the inoculation cylinder 5, ensuring that the push rod 6 will not cause the inoculation cylinder 5 to shift during the inoculation process. If it is necessary to change the inoculum in the inoculation cylinder 5, simply operate the U-shaped clamp 4 to loosen it, and the inoculation cylinder 5 can be easily removed for internal cleaning and replacement with new inoculum.

[0037] The fixed clamping plate 2 has a nut seat 12 vertically positioned at its tail end, and the nut seat 12 is internally threaded with an adjusting bolt 13 for adjusting the clamping distance. When the movable clamping plate 1 is pressed down, its tail end encounters the obstruction of the adjusting bolt 13, thus limiting the rotation angle of the movable clamping plate 1. By rotating the adjusting bolt 13, the stroke of the spring 9 is adjusted, thereby controlling the stroke of the push rod 6, ultimately achieving precise control of the output amount.

[0038] The movable clamp 1 and the fixed clamp 2 are each fixed with a needle 14 at their front ends. When the clamps close, the needle 14 pierces the fermentation substrate, and when the clamps return to their original position, it moves the surrounding substrate to cover the injection hole. During inoculation, the needle 14 first pierces the adjacent fermentation substrate. After the inoculum is injected, the needle 14 moves to the surrounding fermentation substrate by rotating the movable clamp 1 and the fixed clamp 2. Subsequently, the movable clamp 1 returns to its original position, causing the needle 14 to agitate the fermentation substrate to cover the inoculum. Because the fermentation substrate contains abundant fiber, it is easily agitated by the needle 14. When the needle 14 is initially inserted, the surrounding material is gently moved aside along with the movement of the movable clamp 1, so the needle 14 needs to be rotated to the new material position to continue the operation.

[0039] The push rod 6 is equipped with a pull plate 15 at its end. By pulling the pull plate 15, the push rod 6 is moved backward to draw bacteria into the injection cylinder 5 under negative pressure, so that the injection cylinder 5 does not need to be replaced frequently.

[0040] The fixed clamping plate 2 has a slide rail 16 fixedly installed on its inner side, and the pull plate 15 has a guide rod 17 in the opposite direction to the notch 8. The guide rod 17 is slidably engaged in the slide rail 16. By utilizing the synergistic effect of the guide rod 17 and the slide rail 16, the orientation of the notch 8 can be determined, so that the spring 9 can always be accurately embedded in the corresponding notch 8.
