Description

Technical Field

[0001] This invention belongs to the field of greenhouse technology and relates to a greenhouse for edible fungi cultivation. Background Technology

[0002] Edible fungi, as a nutritious and green food, are increasingly popular due to their delicious taste. However, most edible fungi are harvested from the wild, with relatively few cultivated in greenhouses. Current edible fungi cultivation generally employs greenhouse technology for large-scale production. During cultivation, the growing bags on the racks require timely irrigation or spraying to ensure healthy growth. Typically, growers manually spray water onto the growing bags using hoses connected to water pipes, a method that is inefficient and labor-intensive.

[0003] Currently, Chinese patent CN107493958A discloses an energy-saving and environmentally friendly edible mushroom cultivation greenhouse, including a concrete facade, a water trough, a grid, and a fan. A cultivation shed is fixedly installed above the water trough, a cultivation chamber is fixedly installed at the top of the grid, and a cultivation rack is fixedly installed inside the cultivation chamber. A branch pipe is installed above the cultivation rack, with a spray pipe fixedly installed at the bottom of the branch pipe and a main pipe fixedly installed at the top. The main pipe passes through the top of the cultivation chamber and is fixedly connected to the top of a T-junction. The left end of the T-junction is connected to a water gun pipe, and the bottom end of the T-junction is fixedly connected to a water outlet pipe, which is fixedly connected to a water pump. The right end of the water pump is fixedly connected to a water inlet pipe. While this technical solution allows water to be sprayed onto the cultivation bags at the top of the cultivation rack via a spray pipe, for multi-layered cultivation racks, the cultivation bags in the middle and lower layers cannot receive sufficient moisture, which is detrimental to the growth of edible mushrooms in these layers. Furthermore, pre-laying numerous pipes in the greenhouse for spraying operations increases investment costs. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a mushroom cultivation greenhouse that effectively solves the issues of insufficient moisture in the middle and lower layers of the planting bags in existing technologies, which increases input costs.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an edible fungus cultivation greenhouse, comprising a greenhouse body and multiple rows of planting racks disposed within the greenhouse body, wherein a walking track and a spraying mechanism are disposed on the upper part of the greenhouse body, and the spraying mechanism is disposed on the walking track and moves along the walking track; The spraying mechanism includes a power unit connected to a walking track and a fixed sleeve connected to the power unit. The fixed sleeve is fitted with a movable sleeve that slides up and down along it. The lower end of the movable sleeve is connected to a horizontal beam. Both ends of the horizontal beam are connected to support rods. Multiple nozzles are installed on the support rods. The nozzles are connected to a water supply unit through pipes.

The support rod can rotate around the end of the horizontal beam via the folding assembly, and the folding assembly can drive the support rod to remain parallel to the horizontal beam. A limiting mechanism is provided between the fixed sleeve and the movable sleeve to lock the position between them.

[0006] Furthermore, a first pulley is provided at the top of the interior of the fixed sleeve; a traction rope is wound on the first pulley, one end of the traction rope is connected to the end of the movable sleeve, and the other end is connected to a counterweight, which is placed inside the movable sleeve and can move up and down.

[0007] Furthermore, the upper outer side of the movable sleeve is provided with a first bullseye ball that rolls along the inner wall of the fixed sleeve, and the outer side of the counterweight is provided with a second bullseye ball that rolls along the inner wall of the movable sleeve.

[0008] Furthermore, two second pulleys symmetrical about the axis of the first pulley are provided below the first pulley, and the two second pulleys press the traction rope toward the axis of the fixed sleeve.

[0009] Furthermore, each of the second pulleys is connected to a U-shaped frame, and a fixed rod is connected between the two U-shaped frames. The fixed rod has a through hole for the traction rope to pass through.

[0010] Furthermore, the limiting mechanism includes an installation notch formed on the fixed sleeve, an eccentric wheel is rotatably connected inside the installation notch, and a rotating handle is connected to one side of the eccentric wheel.

[0011] Furthermore, the end of the support rod is connected to an upper end plate and a lower end plate that are inserted into the horizontal beam; The folding assembly includes a fixing seat fixed to the lower end plate, a hinge shaft fixed on the bottom surface of the fixing seat, the hinge shaft passing through the lower end plate and extending into a horizontal beam; a compression spring is provided in the middle of the fixing seat, and an end cap is inserted into the fixing seat; a connecting post is provided above the end cap, the connecting post passing through the upper end plate and connected to the horizontal beam; A torsion spring is provided between the connecting post and the end cap.

[0012] Furthermore, the fixing base is provided with a receiving groove, the edge of the receiving groove is provided with a slot, and the end cover is provided with a locking block that matches the slot.

[0013] Furthermore, one end of the connecting column that protrudes from the horizontal beam is threaded with a back-tightening nut, and a multi-faceted frustum is fixed on the end face of the connecting column.

[0014] Furthermore, the spraying mechanism also includes a driven frame that slides on a traveling track. The lower end of the driven frame is connected to a water tank, and a water pump is installed inside the water tank. The water pump is connected to a hose that extends out of the water tank, and the hose is simultaneously connected to multiple nozzles.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the spraying mechanism can travel along the track inside the greenhouse and spray sufficient water onto the planting bags on the planting rack through the nozzles, avoiding the need to lay a lot of pipes in advance and reducing investment costs; and the nozzles can be adjusted up and down through the movable sleeve to adapt to the planting bags on different levels of the planting rack, so that the planting bags on the planting rack can all receive sufficient water and ensure the uniform growth of edible fungi on different levels.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, the present invention proposes an edible fungus cultivation greenhouse, including a greenhouse body 1 and multiple rows of planting racks 2 set inside the greenhouse body 1. The upper part of the greenhouse body 1 is provided with a walking track 3 and a spraying mechanism 4. The spraying mechanism 4 is set on the walking track 3 and moves along the walking track 3. The shed 1 is constructed from welded steel pipes or structural steel. A beam is welded to the upper part of the shed 1, and the walking track 3 is connected to the lower side of the beam by high-strength bolts. The walking track 3 can be made of I-beams. The planting rack 2 is constructed from welded steel pipes and has a multi-layered structure, with edible mushroom planting bags placed on different levels.

[0020] In this embodiment, the spraying mechanism 4 includes a power unit 401 connected to the walking track 3 and a fixed sleeve 402 connected to the power unit 401. The fixed sleeve 402 is fitted with a movable sleeve 403 that slides up and down along it. The lower end of the movable sleeve 403 is connected to a horizontal beam 404, and the two ends of the horizontal beam 404 are connected to support rods 405. Multiple nozzles 406 are provided on the support rods 405, and the nozzles 406 are connected to a water supply unit through pipes. The power unit 401 can provide power to drive the spraying mechanism 4 to move along the walking track 3, so that the movable sleeve 403 in the spraying mechanism 4 passes through the side of the planting rack 2. When it is necessary to spray and irrigate the planting bags on different levels of the planting rack 2, the movable sleeve 403 is slid up and down along the fixed sleeve 402 to adjust its height position, and the water supply unit is turned on. Water is sprayed out from the nozzles 406, so that the nozzles 406 spray and irrigate the planting bags on different levels, so that the planting bags on different levels can receive sufficient water.

[0021] The power unit 401 can be an I-beam electric trolley, with a drive motor as the power source to drive the entire spraying mechanism 4. The I-beam electric trolley is existing technology and will not be described in detail here. The fixed sleeve 402, movable sleeve 403, horizontal beam 404, and support rod 405 are all made of square steel pipes.

[0022] In this embodiment, a limiting mechanism 6 is provided between the fixed sleeve 402 and the movable sleeve 403 to lock the position between the fixed sleeve 402 and the movable sleeve 403; when the movable sleeve 403 has finished adjusting its height up and down along the fixed sleeve 402, the limiting mechanism 6 locks the relative position of the fixed sleeve 402 and the movable sleeve 403 to prevent the movable sleeve 403 from moving downward under its own weight.

[0023] In this embodiment, a folding assembly 5 is provided between the support rod 405 and the horizontal beam 404. The support rod 405 can rotate around the end of the horizontal beam 404 via the folding assembly 5, and the folding assembly 5 can drive the support rod 405 to remain parallel to the horizontal beam 404. When the power unit 401 drives the fixed sleeve 402 and the movable sleeve 403 to move along one side of the planting rack 2, the support rod 405 can extend to the middle of the planting rack 2. The water supply unit provides water to the nozzle 406 through the pipe. During the movement, the nozzle 406 on the support rod 405 sprays water onto the planting bags on the planting rack 2. When the support rod 405 touches the vertical bar on one side of the planting rack 2 during the movement, the support rod 405 can be rotated through the folding assembly. 5. Rotating around the end of the horizontal beam 404, the angle between the support rod 405 and the horizontal beam 404 continuously decreases during the continued movement. When the angle is 90°, the support rod 405 can pass through the vertical bar on one side of the planting rack 2. Under the restoring force of the folding component 5, the drive support rod 405 will rotate and remain parallel to the horizontal beam 404. The support rod 405 can extend to the middle of the planting rack 2 again, ensuring that the nozzle 406 on the support rod 405 can continue to irrigate the planting bags of the planting rack 2. The folding component 5 allows the support rod 405 to flexibly pass through the vertical bar on one side of the planting rack 2 during the movement without stopping the movement of the spraying mechanism 4, which has high applicability and also improves the efficiency of the spraying.

[0024] In this embodiment, a first pulley 407 is provided at the top of the interior of the fixed sleeve 402; a traction rope 408 is wound around the first pulley 407, one end of the traction rope 408 is connected to the end of the movable sleeve 403, and the other end is connected to a counterweight 409. The counterweight 409 is placed inside the movable sleeve 403 and can move up and down; the weight of the counterweight 409 is equal to the total weight of the movable sleeve 403, the horizontal beam 404, the support rod 405 and the nozzle 406 on it, etc. Without external force, the movable sleeve 403 will not slide up and down along the fixed sleeve 402; when it is necessary to adjust the height of the movable sleeve 403 so that the nozzle 406 on the support rod 405 can adapt to the planting bags on different levels of the planting rack 2, the movable sleeve 403 can be pushed up or down; when adjusting the height of the movable sleeve 403 up or down, due to the presence of the counterweight 409, the adjustment can be made with very little effort, which can reduce the amount of labor.

[0025] The first pulley 407 has a shaft rotatably connected to its center, and both ends of the shaft are connected to the side walls of the fixed sleeve 402. The traction rope 408 is made of steel wire rope to improve its service life. A cross is welded to the top of the movable sleeve 403, and a lifting ring is fixed on the counterweight 409. One end of the traction rope 408 is tied to the cross, and the other end is tied to the lifting ring. The counterweight 409 is a square prism with a square cross section and is made of cast iron.

[0026] In this embodiment, the upper outer side of the movable sleeve 403 is provided with a first bullseye ball 410 that rolls along the inner side of the fixed sleeve 402, and the outer side of the counterweight 409 is provided with a second bullseye ball 411 that rolls along the inner wall of the movable sleeve 403. Specifically, both the first bullseye ball 410 and the second bullseye ball 411 are flange-type bullseye balls and are fixedly connected by screws. Two first bullseye balls 410 are provided on each side of the upper end of the movable sleeve 403, and two second bullseye balls 411 are also provided on each side of the counterweight 409. The first bullseye balls 410 and the second bullseye balls 411 can improve the smoothness of the up and down sliding.

[0027] In this embodiment, two second pulleys 412 are provided below the first pulley 407, symmetrical about the axis of the first pulley 407. The two second pulleys 412 press the traction rope 408 towards the axis of the fixed sleeve 402. Under the mutual pressing of the two second pulleys 412, the wrap angle between the traction rope 408 and the first pulley 407 is greater than 180 degrees, which prevents the traction rope 408 from slipping off the first pulley 407 and improves its reliability. A shaft is rotatably connected to the axis of the second pulley 412, and the two ends of the shaft are connected to the side wall of the fixed sleeve 402.

[0028] Furthermore, each second pulley 412 is connected to a U-shaped frame 413, and a fixing rod 414 is connected between two U-shaped frames 413. The fixing rod 414 has a through hole for the traction rope 408 to pass through. Mounting holes are provided on both sides of the U-shaped frame 413 for the shaft of the second pulley 412 to pass through. The fixing rod 414 is integrally connected to the U-shaped frame 413, and the ends of the fixing rods 414 corresponding to the two second pulleys 412 are integrally formed. Therefore, the spacing of the traction ropes 408 located on both sides of the first pulley 407 can be limited, avoiding the traction ropes 408 from getting tangled together and improving the reliability of use.

[0029] In this embodiment, the limiting mechanism 6 includes a mounting notch on the fixed sleeve 402, an eccentric wheel 601 rotatably connected inside the mounting notch, and a rotating handle 602 connected to one side of the eccentric wheel 601; an eccentric shaft is connected to the middle of the eccentric wheel 601, and the two ends of the eccentric shaft are fitted with grooves on the mounting notch, allowing the eccentric shaft to rotate; one side of the eccentric wheel 601 is an arc-shaped part that can abut against the outer wall of the movable sleeve 403. When the height of the movable sleeve 403 is adjusted, the rotating handle 602 is rotated upward, so that the arc-shaped part on the eccentric wheel 601 rotates through the mounting notch into the interior of the fixed sleeve 402, and the arc-shaped part abuts against the outer wall of the movable sleeve 403, locking the position of the movable sleeve 403 and preventing it from moving downward under its own weight; moreover, when locked and without external force, the rotating handle 602 will not move downward, improving the reliability of use. When the height of the movable sleeve 403 needs to be readjusted, the operator will turn the handle 602 downwards so that the arc-shaped part of the eccentric wheel 601 deviates from the outer side of the movable sleeve 403; after the adjustment is completed, the operator will turn the handle 602 upwards again to relock the movable sleeve 403 and the fixed sleeve 402.

[0030] In this embodiment, the end of the support rod 405 is connected to an upper end plate and a lower end plate inserted into the horizontal beam 404; the folding assembly 5 includes a fixing seat 501 fixed to the lower end plate, a hinge shaft fixed on the bottom surface of the fixing seat 501, the hinge shaft passing through the lower end plate and extending out of the horizontal beam 404; a compression spring 502 is provided in the middle of the fixing seat 501, an end cap 503 is inserted into the fixing seat 501, a connecting post 504 is provided above the end cap 503, the connecting post 504 passes through the upper end plate and is connected to the horizontal beam 404; a torsion spring 505 is provided between the connecting post 504 and the end cap 503, the upper end of the torsion spring 505 is connected to the connecting post 504 and the end cap 503. The connecting post 504 is fixedly connected, and its lower end is fixedly connected to the end cap 503. When the torsion spring 505 does not generate elastic potential energy, the support rod 405 and the horizontal beam 404 remain parallel. When the support rod 405 touches the vertical rod on one side of the planting frame 2, the hinge shaft and connecting post 504 cause the support rod 405 to rotate and connect to the end of the horizontal beam 404. The support rod 405 rotates around the end of the horizontal beam 404. During the rotation, the torsion spring 505 accumulates elastic potential energy. When the support rod 405 passes the vertical rod on one side of the planting frame 2, the torsion spring 505 releases its elastic potential energy, causing the support rod 405 to rotate back, so that the support rod 405 and the vertical rod remain parallel again.

[0031] The end of the hinge shaft is connected to the fixed seat 501 via a threaded structure; the compression spring 502 is a conical compression spring 502, which can provide preload when the end cover 503 is inserted into the fixed seat 501, to prevent the end cover 503 from coming out of the fixed seat 501 and improve the reliability of the insertion of the end cover 503 and the fixed seat 501.

[0032] In this embodiment, the fixed base 501 has a receiving groove 506, and the edge of the receiving groove 506 has a slot 507. The end cover 503 has a locking block 508 that matches the slot 507. The slot 507 is connected to the receiving groove 506, and the locking block 508 is integrally connected to the end cover 503. When the end cover 503 is inserted into the receiving groove 506, the locking block 508 is inserted into the slot 507. The slot 507 and the locking block 508 cooperate with each other to restrict the rotation of the end cover 503. When the support rod 405 rotates, the torsion spring 505 can generate elastic potential energy. Multiple slots 507 and locking blocks 508 are provided to improve the reliability of restricting the rotation of the end cover 503.

[0033] In this embodiment, one end of the connecting column 504 extending out of the horizontal beam 404 is threadedly connected to a back-tightening nut 509, and a multi-faceted frustum is fixed on the end face of the connecting column 504. Specifically, the upper end of the connecting column 504 has an external thread, and a matching threaded hole is opened on the horizontal beam 404. The connecting column 504 is connected to the horizontal beam 404 through the threaded structure. Therefore, the back-tightening nut 509 tightens the connecting column 504, preventing the connecting column 504 from rotating during the rotation of the support rod 405. Furthermore, the multi-faceted frustum adopts a hexagonal prism structure, allowing the connecting column 504 to be rotated using tools such as wrenches, making operation convenient.

[0034] Furthermore, to facilitate the installation of the connecting column 504 and the end cap 503, multiple windows can be provided on the horizontal beam 404, allowing workers to insert tools or hands into the horizontal beam 404 for easy operation. In addition, a support column is installed between the connecting column 504 and the end cap 503, positioned in the middle of the torsion spring 505 to support it, preventing it from bending during use and improving reliability.

[0035] In this embodiment, the spraying mechanism 4 also includes a driven frame 415 that slides on the traveling track 3. The lower end of the driven frame 415 is connected to a water tank 416. A water pump is installed in the water tank 416. The water pump is connected to a hose extending out of the water tank 416. The hose is simultaneously connected to multiple nozzles 406. A connecting rod is provided between the driven frame 415 and the power unit 401. The two ends of the connecting rod are connected to the driven frame 415 and the power unit 401 by hinges. When the power unit 401 moves, it can drive the driven frame 415 and the water tank 416 to move accordingly. The water pump in the water tank 416 can supply water in the water tank 416 to the nozzles 406 through the hose to realize water spraying. A water inlet is opened on the water tank 416. When there is no water in the water tank 416, water can be injected into the water tank 416 through water pipes and pipelines.

[0036] In this embodiment, the water supply unit includes a booster pump and a control valve installed inside the shed 1. The booster pump is connected to an external water pipe. Water can be injected into the water tank 416 through the booster pump and the pipe. Alternatively, a long flexible hose can be connected to the outlet of the booster pump, and the hose can be directly connected to the nozzle 406, allowing the booster pump to directly supply water to the nozzle 406. The water pump is also connected to a waterproof cable, which is relatively long and has a running track 3, enabling it to be connected to an external power source to power the water pump.

[0037] In this embodiment, the walking track 3 is set between two adjacent planting racks 2, and the walking track 3 extends continuously in a serpentine shape, so that the spraying mechanism 4 can move continuously between the planting racks 2.

[0038] When using the above technical solution: first, turn on the booster pump to fill the water tank 416 with water, and then turn the rotating handle 602 downward to adjust the height of the movable sleeve 403 so that the nozzle 406 on the support rod 405 can spray water onto the planting bags at the corresponding level; then turn the rotating handle 602 upward to lock the eccentric wheel 601 into the movable sleeve 403; then turn on the power unit 401 and the water pump so that the spraying mechanism 4 can travel along the travel track 3, and at the same time the nozzle 406 sprays water to irrigate the planting bags; When the support rod 405 in the spraying mechanism 4 touches the vertical rod on one side of the planting rack 2, the support rod 405 rotates through the folding assembly 5 and flexibly passes through the vertical rod on one side of the planting rack 2, so that the spraying mechanism 4 does not stop moving. After the support rod 405 passes, the folding assembly 5 can return the support rod 405 to a state that is horizontal with the horizontal beam 404, and continue to spray irrigation on the planting bags on that level. After the planting bags on one level are irrigated, the height of the movable sleeve 403 is readjusted, and the nozzle 406 is moved to another level to irrigate the planting bags on that level, so that the planting bags on different levels of the planting rack 2 can be irrigated and receive sufficient water.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
