Description

Technical Field

[0001] The present invention relates to the field of agriculture, and particularly to a crop cultivation device. Background Art

[0002] The fermented material cultivation method involves mixing various raw materials evenly, piling them up according to specific standards, undergoing a stacking fermentation process for a period of time, and after the temperature inside the pile reaches the standard, 3 to 5 turning operations are required. Subsequently, inoculation is carried out under natural conditions, and the growth of hyphae and the formation of fruiting bodies (mushrooms) are promoted in a suitable temperature and humidity environment. This method is applicable to all edible mushroom species that can be cultivated with raw materials, especially various species of the genus Agaricus, such as Agaricus bisporus, Agaricus bitorquis, and Agaricus blazei (Agaricus blazei Murrill). In addition, Volvariella volvacea, Pleurotus ostreatus, Coprinus comatus, etc. also often use this method.

[0003] In the inoculation process, the spawn is usually broken into pieces the size of red dates to walnuts for manual inoculation. Several points need to be noted for this method: First, the inoculation depth should be appropriate. If it is too deep, it may be difficult for the hyphae to penetrate the covering or cause the hyphae to develop horizontally. If it is too shallow, the growth of the hyphae may be affected due to insufficient nutrients. Second, although electric inoculation tools are convenient to operate, their high cost and the possible physical damage to the spawn mass (such as when the cable is dragged) limit their application. Finally, when manually inoculating, the opening size of the plastic film needs to be controlled properly. If the opening is too large, it will not only cause heat loss and leakage of the fermented material, but also increase the risk of bacterial invasion. If the opening is too small, it will be difficult for the hyphae to penetrate the film. Summary of the Invention

[0004] To solve the defects existing in the prior art, the present invention provides a crop cultivation device that realizes the functions of feeding and inoculation with a fixed depth and fixed quantity in a manual manner, is convenient to hold and use, reduces the operation burden, does not require electricity throughout the process, is purely driven by human power, is economical and practical, and has remarkable effects. The opening size of its plastic film is fixed, ensuring the growth environment of the strains and being beneficial to improving the growth effect.

[0005] The technical solution adopted by the present invention is: a crop cultivation device, including a movable clamping plate and a fixed clamping plate. 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 feeding cylinder is detachably clamped inside the U-shaped clamp. The front end of the feeding cylinder is provided with a necking structure;

[0007] A push rod is slidably and coaxially fitted inside the feeding cylinder. The top end of the push rod is fixed with a push head that is hermetically fitted with the inner wall of the feeding cylinder. The surface of the push rod is evenly distributed with notches inclined towards the discharge port of the feeding cylinder along the axial direction;

[0008] The inner side of the movable splint is fixed with a reed, the reed inclines towards the discharging end of the feeding cylinder, and the thickness of its free end is less than the width of the notch so as to be embedded into the notch to realize a one-way clamping structure;

[0009] The front ends of both the movable splint and the fixed splint form a sharp structure that inclines inwards, and the tips contact to form a puncture structure when closed. When the front end of the device penetrates the plastic film, a smaller jack can be formed, which can not only reduce the leakage of the fermentation material, but also effectively block the invasion of bacteria, while ensuring that the pore size is moderate and will not hinder the strain from penetrating the film. In addition, once the plastic film is punctured, the wide parts of the movable splint and the fixed splint will stop further penetration due to the blockage of the plastic film, thus realizing the precise control of the planting depth.

[0010] Working principle:

[0011] During inoculation, hold the movable splint and the fixed splint and use their tips to penetrate the plastic film covering and pierce into the fermentation material. By squeezing, make the movable splint approach the fixed splint. At this time, the front ends of the two splints unfold to form an injection gap. At this time, the end of the reed is stuck into the corresponding notch. Since the notch inclines towards the discharging port of the feeding cylinder, this can prevent the reed from slipping out of the notch and at the same time the reed will not drive the push rod to retract when the movable splint resets. Since the reed has elasticity but a constant length, when continuously pressing down the movable splint, the elastic potential energy of the reed is converted into the thrust on the push rod, thereby driving the push rod to perform an axial feeding movement to realize the precise injection of the strain solution. After inoculation, vertically lift the device and release the pressure on the movable splint. At this time, the reed automatically disengages from the notch due to elastic reset to prepare for the subsequent inoculation operation. The entire cycle effectively guarantees the inoculation accuracy and operation efficiency.

[0012] Preferably, a torsion spring is provided on the hinge shaft of the hinge plate for driving the movable splint and the fixed splint to automatically reset to the closed state, so that the reed disengages from the notch, so that the reed can be engaged with other notches to push the push rod.

[0013] Preferably, a fixing groove is provided inside the U-shaped clamp, and a positioning convex block that can be embedded into the fixing groove is provided at the corresponding position on the outer wall of the feeding cylinder. The cooperation of the fixing groove and the positioning convex block is used to stabilize the position of the feeding cylinder to ensure that the pushing of the push rod during inoculation will not cause the feeding cylinder to shift. If it is necessary to replace the strain in the feeding cylinder, just operate the U-shaped clamp to loosen it, and then the feeding cylinder can be easily removed for internal cleaning and replacement of a new strain.

[0014] Preferably, a nut seat is vertically provided at the tail of the fixed splint, and an adjusting bolt for adjusting the clamping distance is threadedly connected inside the nut seat. When the movable splint is pressed down, its tail end will encounter the blockage of the adjusting bolt, thereby restricting the rotation angle of the movable splint. By rotating the adjusting bolt to adjust the stroke of the reed, and then controlling the stroke of the push rod, finally realizing the precise control of the discharging amount.

[0015] Preferably, a needle is fixed at the front ends of the movable clamping plate and the fixed clamping plate. When the clamping plates are closed, the needle pierces into the fermented material substrate, and drives the surrounding substrate to cover the material injection hole when the clamping plates reset. During the inoculation process, the needle will first pierce into the adjacent fermented material. After the strain injection is completed, by rotating the movable clamping plate and the fixed clamping plate, the needle will move into the surrounding fermented material accordingly. Subsequently, the movable clamping plate resets, driving the needle to stir the fermented material to cover the strain. Since the fermented material contains rich fibers, it is easy to be stirred by the needle. When the needle is initially inserted, along with the movement of the movable clamping plate, the materials around it have been gently pushed aside, so the needle needs to be rotated to a new material position to continue the operation.

[0016] Preferably, a pull plate is arranged at the end of the push rod. By pulling the pull plate backward, the push rod moves backward to suck the strain into the injection cylinder by negative pressure, without frequently replacing the injection cylinder.

[0017] Preferably, a slide rail is fixedly arranged on the inner side of the fixed clamping plate, and a guide rod with a direction opposite to the notch direction is arranged on the pull plate. The guide rod is slidably matched in the slide rail. By the synergistic effect of the guide rod and the slide rail, the orientation of the notch can be determined, so that the reed can always be accurately inserted into the corresponding notch.

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

[0019] 1. By setting the movable clamping plate, the fixed clamping plate and the reed, since the reed has elasticity but a constant length, when the movable clamping plate is continuously pressed down, the elastic potential energy of the reed is converted into the thrust on the push rod, thereby driving the push rod to perform an axial feeding motion to achieve the precise injection of the strain solution. After the inoculation is completed, the device is vertically lifted and the pressure on the movable clamping plate is released. At this time, the reed automatically disengages from the notch due to elastic reset to prepare for the subsequent inoculation operation. The entire cycle process effectively ensures the inoculation accuracy and operation efficiency, and the device is easy to hold, the operation is convenient and labor-saving, and it is a pure manual operation with low cost.

[0020] 2. By the cooperation of the nut and the adjusting bolt assembled at the tail end of the fixed clamping plate, the front end parts of the movable clamping plate and the fixed clamping plate form a sharp structure inclined inward, and the tips contact to form a puncture structure when closed, realizing precise depth and quantitative inoculation, with good inoculation effect. At the same time, the plastic film opening is fixed, providing good guarantee for the growth of the strain. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

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

[0029] A U-shaped clamp 4 is fixed inside the fixed clamping plate 2, and a charging cylinder 5 is detachably clamped inside the U-shaped clamp 4. The front end of the charging cylinder 5 is provided with a reduced diameter structure;

[0030] A push rod 6 is coaxially and slidably fitted inside the charging cylinder 5. A push head 7 that is hermetically fitted with the inner wall of the charging cylinder 5 is fixed at the top of the push rod 6. The surface of the push rod 6 is uniformly distributed with notches 8 that are inclined towards the discharge port of the charging cylinder 5 along the axial direction;

[0031] A reed 9 is fixed inside the movable clamping plate 1. The reed 9 is inclined towards the discharge end of the charging cylinder 5, and the thickness of its free end is less than the width of the notch 8 so as to be embedded in the notch 8 to realize a one-way clamping structure;

[0032] The front end parts of the movable clamping plate 1 and the fixed clamping plate 2 both form sharp structures that are inclined inwards, and the tips contact when closed to form a puncture structure. When the front end of the device penetrates the plastic film, a smaller jack can be formed, which can not only reduce the leakage of fermented materials, but also effectively block the intrusion of bacteria, while ensuring that the aperture size is appropriate and will not hinder the penetration of the strain through the film. In addition, once the plastic film is punctured, the wide parts of the movable clamping plate 1 and the fixed clamping plate 2 will stop further penetration due to the obstruction of the plastic film, thereby realizing precise control of the planting depth.

[0033] Working principle:

[0034] During inoculation, hold the movable clamping plate 1 and the fixed clamping plate 2 by hand and use their tips to penetrate the plastic film and stab into the fermented material. By pinching operation, make the movable clamping plate 1 close to the fixed clamping plate 2. At this time, the front ends of the two clamping plates unfold to form an injection gap. At this time, the end of the reed 9 is stuck into the corresponding notch 8. Since the notch 8 is inclined towards the discharge port of the injection cylinder 8, this can prevent the reed 9 from slipping out of the notch 8 and disengaging. At the same time, when the movable clamping plate 1 resets, the reed 9 will not drive the push rod 6 to retract. Since the reed 9 has elasticity but a constant length, when the movable clamping plate 1 is continuously pressed down, the elastic potential energy of the reed 9 is converted into the thrust on the push rod 6, thereby driving the push rod 6 to perform an axial feeding motion and realizing the precise injection of the strain solution. After inoculation, vertically lift the device and release the pressure on the movable clamping plate 1. At this time, the reed 9 automatically disengages from the notch 8 due to elastic reset to prepare for subsequent inoculation operations. The entire cycle effectively ensures the inoculation accuracy and operation efficiency.

[0035] Among them, a torsion spring is provided on the hinge shaft of the hinge plate 3, which is used to drive the movable clamping plate 1 and the fixed clamping plate 2 to automatically reset to the closed state, so that the reed 9 disengages from the notch 8, so that the reed 9 can be engaged with other notches 8 to push the push rod 6.

[0036] Among them, a fixed groove 10 is provided inside the U-shaped clamp 4, and a positioning convex block 11 that can be embedded in the fixed groove 10 is provided at the corresponding position on the outer wall of the injection cylinder 5. The cooperation of the fixed groove 10 and the positioning convex block 11 is used to stabilize the position of the injection cylinder 5 to ensure that the push of the push rod 6 during inoculation will not cause the injection cylinder 5 to shift. If it is necessary to replace the strain in the injection cylinder 5, just operate the U-shaped clamp 4 to loosen it, and then the injection cylinder 5 can be easily removed for internal cleaning and replacement of a new strain.

[0037] Among them, a nut seat 12 is vertically provided at the tail of the fixed clamping plate 2, and an adjusting bolt 13 for adjusting the clamping distance is threadedly connected inside the nut seat 12. When the movable clamping plate 1 is pressed down, its tail end will encounter the block of the adjusting bolt 13, thereby restricting the rotation angle of the movable clamping plate 1. By rotating the adjusting bolt 13, the stroke of the reed 9 is adjusted, and then the stroke of the push rod 6 is controlled, and finally the precise regulation of the discharge amount is realized.

[0038] Among them, a needle pusher 14 is fixed to the front ends of the movable splint 1 and the fixed splint 2. When the splints are closed, the needle pusher 14 pierces into the fermented material substrate, and drives the surrounding substrate to cover the injection hole when the splints are reset. During the inoculation process, the needle pusher 14 will first pierce into the adjacent fermented material. After the strain injection is completed, by rotating the movable splint 1 and the fixed splint 2, the needle pusher 14 will move into the surrounding fermented material accordingly. Subsequently, the movable splint 1 is reset, driving the needle pusher 14 to stir the fermented material to cover the strain. Since the fermented material contains rich fibers, it is easy to be stirred by the needle pusher 14. When the needle pusher 14 is initially inserted, along with the movement of the movable splint 1, the materials around it have been gently pushed aside. Therefore, the needle pusher 14 needs to be rotated to a new material position to continue the operation.

[0039] Among them, a pull plate 15 is arranged at the end of the push rod 6. By pulling the pull plate 15 backward, the push rod 6 moves backward to suck the strain into the injection cylinder 5 by negative pressure, without frequently replacing the injection cylinder 5.

[0040] Among them, a slide rail 16 is fixedly arranged on the inner side of the fixed splint 2, and a guide rod 17 with a direction opposite to that of the notch 8 is arranged on the pull plate 15. The guide rod 17 is slidably fitted in the slide rail 16. By 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 reed 9 can always be accurately inserted into the corresponding notch 8.
