Description

Technical Field

[0001] The present invention relates to the field of edible mushroom inoculation, and more specifically, to an inoculation tool for liquid strains of edible mushrooms. Background Art

[0002] Edible mushrooms refer to large fungi that can be eaten by humans daily. They have rich flavors and high edible values, and have the advantages of small investment, short cycle, and quick results. Therefore, they are widely promoted in the field of agricultural planting.

[0003] The cultivation process of edible mushrooms usually adopts the inoculation method. Liquid strains need to use an inoculation device during the inoculation process. The liquid strains are sprayed into the substrate through the inoculation device. In the existing inoculation devices for liquid strains of edible mushrooms, the inoculation gun head is usually directly connected to a pump, and the spraying of the strains is realized by means of the pumping of the pump. During the inoculation process, the single inoculation quantity of the liquid strains is controlled by the start and stop of the pump or the opening time of the gun head. Manual operation is difficult to achieve quantitative inoculation operation of the liquid strains, which is likely to affect the actual inoculation effect.

[0004] Therefore, we propose an inoculation tool for liquid strains of edible mushrooms to solve some problems existing in the above-mentioned prior art. Summary of the Invention

By installing a quantitative tank below the connecting pipe and fixedly connecting the feed pipe to the inside of the quantitative tank, the quantitative tank can be used to control the quantity of strains inoculated each time. By slidably connecting a valve plate inside the quantitative tank and adjusting the valve plate by means of the threaded connection between a screw rod and a screw sleeve, the device can flexibly adjust the single inoculation quantity according to the actual inoculation requirements. At the same time, by slidably connecting a top plate below the inside of the quantitative tank and fixedly connecting an air pump to an air inlet pipe, the strains inside the quantitative tank can be instantly ejected by means of gas blowing, which is beneficial to improving the uniformity when the strains are ejected from the first spray pipe, and to a certain extent improves the inoculation effect of liquid strains of edible mushrooms.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the advantages of the present invention are as follows:

[0022] (1) In this solution, the metering tank is installed below the connecting pipe, and the feeding pipe is fixedly communicated with the inside of the metering tank. With the help of the metering tank, the number of strains inoculated each time can be controlled. By slidably connecting the valve plate inside the metering tank and adjusting the valve plate by means of the threaded connection between the screw rod and the screw sleeve, the device can flexibly adjust the number of strains inoculated each time according to the actual inoculation requirements. At the same time, by slidably connecting the top plate below the inside of the metering tank and fixedly connecting the air pump to the air inlet pipe, the strains inside the metering tank can be instantly ejected by the blowing of gas, which is beneficial to improving the uniformity when the strains are ejected from the first spray pipe, and to a certain extent, improving the effect of inoculating edible mushroom liquid strains.

[0023] (2) By slidably connecting the second spray pipe inside the first spray pipe, the second spray pipe can be automatically protruded outwards when the strains are ejected. With the elastic pulling of the first spring, the second spray pipe can automatically retract and reset after protruding outwards, so that the device can be applicable to the inoculation operation of edible mushrooms in substrates with different depths. At the same time, by uniformly arranging a plurality of spraying holes on the outer end walls of the first spray pipe and the second spray pipe, the atomization effect when the strains are ejected can be effectively improved, which is beneficial to improving the uniformity and comprehensiveness during the inoculation of the strains.

[0024] (3) By movably sleeving the adjusting sleeve and the sleeve on the outside of the first nozzle, and threadedly connecting the adjusting sleeve to the first nozzle, when the adjusting sleeve is rotated, the sleeve can be driven to move. Since a plurality of injection holes are respectively formed in the front and rear end walls of the first nozzle and the second nozzle, the movement of the adjusting sleeve and the sleeve can be used to block the plurality of injection holes one by one, which is beneficial to flexibly changing the number of open injection holes, enabling the device to be flexibly adjusted according to the usage situation. By providing a U-shaped groove at the bottom of the sleeve, it is possible to prevent the sleeve from being blocked by the connecting pipe during movement, effectively ensuring the working stability of the device.

[0025] (4) By fixedly installing a protective cover having a disc-shaped structure on the outside of the adjusting sleeve, when the adjusting sleeve moves and adjusts, the protective cover can be driven to move synchronously. During use, the protective cover covers the outside of the substrate, which can prevent the bacteria from escaping outward during the inoculation process, being beneficial to improving the stability during the bacteria inoculation process. At the same time, by setting the edge position of the protective cover to a leftward curved structure, the stability of the protective cover fitting on the substrate can be improved.

[0026] (5) By connecting a backflow pipe to the outer end wall of the metering tank, and connecting an external suction pump connected to the bacteria tank to the backflow pipe, when the external suction pump is started, the liquid bacteria can be driven to circulate between the bacteria tank and the metering tank, realizing automatic feeding, which is beneficial to improving the convenience of use of the device. At the same time, by symmetrically arranging the backflow pipe and the feed pipe, it is beneficial to ensure that the liquid bacteria can fully fill the metering tank. By installing a one-way valve inside the inner pipe, the flow direction inside the inner pipe can be restricted, preventing foreign substances from entering the metering tank from the inner pipe when feeding into the metering tank, effectively ensuring the working stability of the device.

[0027] (6) By fixedly installing two blocking plates corresponding to the feed pipe and the backflow pipe at the bottom of the top plate, when the top plate moves upward, the two blocking plates are driven to move upward synchronously, realizing the blocking of the connection between the feed pipe and the backflow pipe and the inner end wall of the metering tank, and the automatic cutoff of feeding can be achieved during the movement of the top plate, which is beneficial to ensuring that the spraying and feeding of the device do not interfere with each other and ensuring the stability during the working process of the device.

[0028] (7) By fixedly connecting a second spring between the top plate and the metering tank, with the help of the resilience brought by the elastic deformation of the second spring, the top plate can automatically reset when it loses the air flow impact at the bottom after moving upward, facilitating the stable cyclic operation of the device.

[0029] (8) By slidably connecting a slider inside the slider, with the help of the movement of the slider, the air inlet hole can be blocked and opened, which is beneficial to flexibly controlling the action of the air flow on the top plate. By rotatably connecting a swing arm to the outer end wall of the metering tank and elastically supporting it with a third spring, the upper end of the swing arm can automatically rebound after being pressed and rotated, facilitating the cyclic use of the device.

[0030] (9) By setting the interiors of the slider and the sliding rod as a mutually connected hollow structure, opening a through-hole corresponding to the air inlet hole at the top of the slider, and connecting the right end of the sliding rod to the outside, when the slider moves to the bottom of the air inlet hole to block the air intake below, the gas between the top plate and the bottom of the quantitative tank can be discharged outward through the air inlet hole from the slider and the sliding rod, which is convenient for avoiding the influence on its reset caused by the gas being blocked and unable to be discharged below the top plate, and is beneficial to ensuring the working stability of the device.

[0031] (10) By symmetrically rotatably connecting two swing arms to the front and rear outer end walls of the quantitative tank, and fixedly connecting a pressure strip with an arc-shaped structure between the upper ends of the two swing arms, the structural stability during the rotation of the swing arms can be effectively improved.

[0047] Embodiment 1:

[0048] Please refer to Figures 1-10, An inoculation tool for edible mushroom liquid spawn, comprising a metering tank 1. On the left side of the top of the metering tank 1, a vertically arranged connecting pipe 101 is fixedly installed, and on the left side of the top end of the connecting pipe 101, a horizontally arranged first spray pipe 102 is fixedly connected. Inside the upper part of the metering tank 1, a valve plate 2 is slidably connected, and inside the valve plate 2, a vertically penetrating inner pipe 201 is fixedly inlaid. The inner pipe 201 is movably inserted into the inside of the connecting pipe 101. On the top of the metering tank 1, a screw sleeve 202 is fixedly installed, and inside the screw sleeve 202, a screw rod 203 is threadedly connected. The bottom end of the screw rod 203 is rotatably connected to the top of the valve plate 2;

[0049] Below the outer end wall of the metering tank 1, a feed pipe 3 is fixedly communicated. Inside the lower part of the metering tank 1, a top plate 301 is slidably connected. On the bottom end wall of the metering tank 1, an air inlet hole 302 is opened. At the bottom of the metering tank 1, a transfer chamber 303 connected to the air inlet hole 302 is fixedly connected, and at the bottom of the transfer chamber 303, an air inlet pipe 304 is fixedly communicated. The feed pipe 3 is fixedly connected to a spawn tank through a pipeline, and the air inlet pipe 304 is fixedly communicated with the air outlet of an external air pump through a pipeline.

[0050] Please refer to Figure 7 , When the device works, raise the position of the spawn tank. Under the action of gravity, the liquid spawn in the spawn tank enters the inside of the metering tank 1 through the pipeline from the feed pipe 3, so that the liquid spawn enters the space between the valve plate 2 and the top plate 301 inside the metering tank 1. Subsequently, the staff controls the air pump connected to the air inlet pipe 304 to be powered on and started, and instantaneously supplies air to the part below the top plate 301 inside the metering tank 1. Under the push of the gas, the top plate 301 instantaneously moves upward, pushing the liquid spawn into the inside of the connecting pipe 101 through the inner pipe 201, and then spraying out through the first spray pipe 102, realizing the inoculation operation of the liquid spawn. Limited by the internal space of the metering tank 1, the quantity of the liquid spawn inoculated each time can be quantitatively controlled.

[0051] If it is necessary to adjust the space for temporarily storing the liquid spawn inside the metering tank 1, only need to rotate the screw rod 203 threadedly connected inside the screw sleeve 202. Driven by the thread, the screw rod 203 drives the valve plate 2 to move up and down inside the metering tank 1 to adjust, controlling the quantity of the liquid spawn stored each time inside the metering tank 1. By installing the metering tank 1 below the connecting pipe 101 and fixedly communicating the feed pipe 3 with the inside of the metering tank 1, the quantity of the spawn inoculated each time can be controlled by means of the metering tank 1.

[0052] By slidably connecting the valve plate 2 inside the metering tank 1 and adjusting the valve plate 2 by means of the threaded connection between the screw 203 and the nut sleeve 202, the device can flexibly adjust the quantity of single inoculation according to the actual inoculation requirements. At the same time, by slidably connecting the top plate 301 below the inside of the metering tank 1 and fixedly connecting the air pump to the air inlet pipe 304, the strains inside the metering tank 1 can be instantaneously ejected by means of gas blowing, which is beneficial to improving the uniformity when the strains are ejected from the first spray pipe 102, and to a certain extent improves the effect of inoculating edible mushroom liquid strains.

[0053] Please refer to Figure 3 As shown in the figure, a second spray pipe 103 is slidably inserted inside the left end of the first spray pipe 102. A plurality of injection holes 104 are formed on the outer end walls of the second spray pipe 103 and the injection holes 104. A first spring 105 is fixedly connected between the right end of the second spray pipe 103 and the inner end wall of the first spray pipe 102. When the device works, by slidably connecting the second spray pipe 103 inside the first spray pipe 102, the second spray pipe 103 can be driven to automatically protrude outwards when the strains are ejected. With the elastic pulling of the first spring 105, the second spray pipe 103 can automatically retract and reset after protruding outwards, so that the device can be applicable to the inoculation operation of edible mushrooms inside substrates with different depths. At the same time, by uniformly arranging a plurality of injection holes 104 on the outer end walls of the first spray pipe 102 and the second spray pipe 103, the atomization effect when the strains are ejected can be effectively improved, which is beneficial to improving the uniformity and comprehensiveness during the inoculation of the strains.

[0054] Please refer to Figures 2-3 and Figure 9 As shown in the figure, an adjusting sleeve 4 and a sleeve 401 are respectively sleeved on the outer end wall of the first spray pipe 102. The adjusting sleeve 4 is threadedly connected to the first spray pipe 102. The sleeve 401 is rotatably connected to the right end of the adjusting sleeve 4. A U-shaped groove 402 adapted to the connecting pipe 101 is formed on the right side of the bottom of the sleeve 401. A plurality of injection holes 104 are respectively formed on the front and rear outer end walls of the first spray pipe 102 and the second spray pipe 103. When the device works, by movably sleeving the adjusting sleeve 4 and the sleeve 401 on the outside of the first spray pipe 102 and threadedly connecting the adjusting sleeve 4 to the first spray pipe 102, rotating the adjusting sleeve 4 can drive the sleeve 401 to move. Since a plurality of injection holes 104 are respectively formed on the front and rear end walls of the first spray pipe 102 and the second spray pipe 103, the movement of the adjusting sleeve 4 and the sleeve 401 can be used to block the plurality of injection holes 104 one by one, which is beneficial to flexibly changing the opening number of the injection holes 104, so that the device can be flexibly adjusted according to the usage situation. By forming the U-shaped groove 402 on the bottom of the sleeve 401, it is possible to prevent the sleeve 401 from being blocked by the connecting pipe 101 during movement, effectively ensuring the working stability of the device.

[0055] Please refer to Figure 1, a protective cover 403 with a disc-shaped structure is fixedly installed on the outer end wall of the adjusting sleeve 4, and the outer edge position of the protective cover 403 is set to a left-bending structure. When the device works, by fixedly installing the protective cover 403 with a disc-shaped structure on the outside of the adjusting sleeve 4, the movement and adjustment of the adjusting sleeve 4 can drive the protective cover 403 to move synchronously. During use, the protective cover 403 covers the outside of the substrate, which can prevent the bacterial species from escaping outward during the inoculation process, and is beneficial to improving the stability during the bacterial species inoculation process. At the same time, by setting the edge position of the protective cover 403 to a left-bending structure, the stability of the protective cover 403 fitting on the substrate can be improved.

[0056] Please refer to Figure 3 , a back-drawing pipe 5 symmetrically arranged with the feed pipe 3 is fixedly connected to the outer end wall of the metering tank 1, and the back-drawing pipe 5 is fixedly connected to the water inlet end of an external pump through a pipeline. The water outlet end of the external pump is fixedly connected to the bacterial tank. A one-way valve is fixedly installed inside the inner pipe 201. When the device works, the external pump is powered on and started. Under the pumping action of the pump, the air flow inside the device flows from the feed pipe 3 into the back-drawing pipe 5. Since both the feed pipe 3 and the water outlet end of the external pump are fixedly connected to the bacterial tank, under the pumping force, the liquid bacterial species in the bacterial tank enter the metering tank 1 through the feed pipe 3, and then flow back to the bacterial tank through the back-drawing pipe 5 and the external pump, automatically adding the bacterial species to the inside of the metering tank 1 in a cycle. By connecting the back-drawing pipe 5 to the outer end wall of the metering tank 1 and connecting the external pump connected to the bacterial tank to the back-drawing pipe 5, when the external pump is started, it can drive the liquid bacterial species to circulate between the bacterial tank and the metering tank 1, realizing automatic feeding, which is beneficial to improving the convenience of use of the device. At the same time, by symmetrically arranging the back-drawing pipe 5 and the feed pipe 3, it is beneficial to ensure that the liquid bacterial species can fully fill the inside of the metering tank 1. By installing the one-way valve inside the inner pipe 201, the flow direction inside the inner pipe 201 can be restricted, preventing foreign matters from entering the metering tank 1 from the inner pipe 201 when feeding the metering tank 1, effectively ensuring the working stability of the device.

[0057] Please refer to Figure 3, two vertically arranged blocking plates 501 are fixedly connected to the bottom of the top plate 301. The two blocking plates 501 are slidably inserted into the bottom of the metering tank 1. The two blocking plates 501 are respectively arranged corresponding to the feed pipe 3 and the back suction pipe 5. The outer end wall of the blocking plate 501 is attached to the inner end wall of the metering tank 1. When the device works, by fixedly installing the two blocking plates 501 corresponding to the feed pipe 3 and the back suction pipe 5 at the bottom of the top plate 301, when the top plate 301 moves upward, it drives the two blocking plates 501 to move upward synchronously, realizing the blocking of the connection between the feed pipe 3 and the back suction pipe 5 and the inner end wall of the metering tank 1, and can automatically cut off the feed during the movement of the top plate 301, which is beneficial to ensuring that the spraying and feeding of the device do not interfere with each other and ensuring the stability of the device during operation.

[0058] Please refer to Figure 3 and Figure 7 , a second spring 502 is fixedly connected between the bottom of the top plate 301 and the inner end wall of the bottom of the metering tank 1. When the device works, by fixedly connecting the second spring 502 between the top plate 301 and the metering tank 1, with the help of the resilience brought by the elastic deformation of the second spring 502, the top plate 301 can automatically reset when it loses the impact of the bottom air flow after moving upward, which is convenient for the device to work stably in a cycle.

[0059] Please refer to Figure 7 , a slider 6 is slidably connected inside the transfer bin 303, and a slide rod 601 is fixedly connected to the right end of the slider 6. The slide rod 601 movably penetrates to the outside of the right end wall of the transfer bin 303. A longitudinally arranged connecting pin 602 is fixedly installed on the outer end wall of the slide rod 601. A swing arm 603 is rotatably connected to the outer end wall of the metering tank 1. A through groove 605 is opened at the lower end of the swing arm 603. The connecting pin 602 is movably inserted into the inside of the through groove 605. A third spring 606 is fixedly connected between the upper end of the swing arm 603 and the outer end wall of the metering tank 1. When the device works, by slidably connecting the slider 6 inside the slider 6, with the help of the movement of the slider 6, the air inlet hole 302 can be blocked and opened, which is beneficial to flexibly controlling the action condition of the air flow on the top plate 301. By rotatably connecting the swing arm 603 to the outer end wall of the metering tank 1 and elastically supporting it with the help of the third spring 606, the upper end of the swing arm 603 can automatically rebound after being pressed and rotated, which is convenient for the device to be used in a cycle.

[0060] Please refer to Figure 7 and Figure 10, both the slider 6 and the slide bar 601 are provided with a hollow structure inside. A through hole corresponding to the air inlet hole 302 is opened at the top of the slider 6, and the right end of the slide bar 601 is communicated with the outside. When the device works, by setting the inside of the slider 6 and the slide bar 601 as a mutually communicated hollow structure, opening the through hole corresponding to the air inlet hole 302 at the top of the slider 6, and communicating the right end of the slide bar 601 with the outside, when the slider 6 moves to the bottom of the air inlet hole 302 to block the air intake below, the gas between the top plate 301 and the bottom of the metering tank 1 can be discharged outwards through the air inlet hole 302 from the slider 6 and the slide bar 601, which is convenient to avoid the influence on its reset caused by the gas being blocked and unable to be discharged below the top plate 301, and is beneficial to ensuring the working stability of the device.

[0061] Please refer to Figures 5-6 , there are two swing arms 603 in total. The two swing arms 603 are symmetrically rotatably connected to the outer end walls on the front and rear sides of the metering tank 1. A pressing strip 604 with an arc-shaped structure is fixedly connected between the upper ends of the two swing arms 603. When the device works, by symmetrically rotatably connecting the two swing arms 603 to the front and rear outer end walls of the metering tank 1 and fixedly connecting the pressing strip 604 with an arc-shaped structure between the upper ends of the two swing arms 603, the structural stability during the rotation of the swing arms 603 can be effectively improved.
