A germination chamber

Abstract

This invention relates to the field of seed germination equipment technology, and more particularly to a germination chamber, comprising a chamber body and a control panel mounted on the chamber body. Transparent doors are symmetrically installed on the chamber body, and an electric lifting plate is mounted on the chamber body. The invention first opens the closed doors, then starts the drive motor to rotate the lead screw. The lead screw, through a threaded block, moves a support frame up and down. This up-and-down movement of the support frame adjusts the height of the seedbed. When the height of the support frame is adjusted to a suitable position for seed germination, the drive motor is turned off. The electric lifting plate and belt conveyor then move the seedbed into the chamber and onto the support frame for germination. Thus, by adjusting the height of the support frame, different microenvironments can be created to adapt to the germination needs of different seeds, thereby improving the seed germination effect and survival rate.

Description

Technical Field

[0001] This invention relates to the field of seed germination equipment technology, and more particularly to a germination chamber. Background Technology

[0002] In modern agricultural practice, the germination chamber is a key facility for seed germination and early growth. Its internal layout and functional design directly affect the germination efficiency and survival rate of seeds. It can improve the germination rate and uniformity of seeds, save seeds and reduce seedling costs, ensure the excellent quality of superior forest tree varieties, and adapt to different environmental conditions.

[0003] Chinese Patent CN221058739U discloses a germination chamber, including a chamber body with a seedbed inlet / outlet at one end and an electric curtain at the top of the other end. Inside the chamber is a support frame with several seedbed support layers. Parallel guide rails are fixedly installed on each seedbed support layer of the support frame. A drive-driven trolley is slidably mounted on each guide rail along its length. A seedbed blocking mechanism is also provided on the guide rails to prevent the seedbeds from automatically slipping off. This blocking mechanism is located at the end of the guide rails near the seedbed inlet / outlet. While this patent allows the seedbeds to be moved indoors, the fixed design of the support frame prevents the height of the seedbeds from being adjusted, making it difficult to meet the germination requirements of different seeds. Furthermore, as seeds grow, their needs for light, ventilation, and other conditions change. The fixed-height support frame cannot adapt to these changes, affecting the germination effect and survival rate.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a germination chamber is proposed that can flexibly adjust the height of the support frame so that the height of the seedbed can be adjusted to meet the germination requirements of different seeds and improve the germination effect and survival rate of seeds. Summary of the Invention

[0005] To overcome the limitations of the fixed support frame used in the aforementioned patents, which prevents the height of the seedbed from being adjusted and thus makes it difficult to meet the germination requirements of different seeds, and to address the drawback of fixed-height support frames that cannot adapt to these changes, thus affecting seed germination efficiency and survival rate, this invention provides a germination chamber with a flexibly adjustable support frame height, allowing for adjustable seedbed height to meet the germination needs of different seeds and improving seed germination efficiency and survival rate.

[0006] This invention is achieved through the following technical solution:

[0007] A germination chamber includes a chamber body and a control panel mounted on the chamber body. Transparent doors are symmetrically installed on the chamber body. An electric lifting plate is mounted on the chamber body, and belt conveyor assemblies are symmetrically installed on the electric lifting plate for moving seedbeds. A shell is fixed to the chamber body. The chamber body also includes a material clamping assembly mounted on the electric lifting plate for moving the seedbeds and contacting the belt conveyor assemblies. Vertically sliding supports are evenly spaced between the two sides of the chamber body for placing the seedbeds. The supports have evenly spaced through holes, and a threaded block is fixed to the inner side of one through hole in each row. The threaded blocks are staggered from left to right. Rotary supports are evenly spaced on the chamber body. A drive screw is connected to the housing, passing through a through hole and threadedly connected to a threaded block. Drive motors are fixedly connected at even intervals inside the housing. The output shaft end of the drive motor is fixedly connected to the end of the drive screw. The drive motor and control panel are electrically connected via a control module. The drive motor drives the drive screw to rotate, and the drive screw drives the support frame to move via the threaded block, allowing the support frame to adjust the height of the seedbed. An n-type brush is slidably connected to the support frame to remove impurities. A screw threadedly connected to the n-type brush is rotatably connected to the support frame. A rotating assembly is provided between the chamber and the support frame to drive the screw to rotate.

[0008] Further explanation: The material clamping assembly includes electric push rods symmetrically mounted on the electric lifting plate. The telescopic rod end of the electric push rod is fixed to a mounting block, and an electric lifting block is mounted on the mounting block for driving the seedbed to move and contact the belt conveyor assembly.

[0009] Further explanation: The drive assembly includes a worm gear and a movable block that are slidably connected to a lead screw via a spline. The movable block is located to the left of the worm gear and is rotatably connected to the worm gear. A cylinder is fixedly connected to the support frame, and the end of the cylinder's telescopic rod is fixedly connected to the movable block. A spline shaft is rotatably connected to the chamber. Hollow worms corresponding to the worm gear are slidably mounted on the spline shaft at even intervals. A cross plate that is rotatably connected to the bottom end of the hollow worm is slidably mounted on the spline shaft at even intervals. The cross plate is slidably connected to the movable block. A stepper motor is mounted on the housing, and the end of the stepper motor's output shaft is fixedly connected to the end of the spline shaft.

[0010] Further explanation: the germination chamber also includes a pressing assembly, which includes a connecting plate fixed to the mounting block. An L-shaped pressing plate is slidably connected to the connecting plate. The L-shaped pressing plate slidably passes through the electric lifting plate to press and fix the seedbed. A return spring is connected between the L-shaped pressing plate and the connecting plate. A triggering assembly is provided between the electric lifting plate and the L-shaped pressing plate to drive the L-shaped pressing plate to move.

[0011] Further explanation: The triggering component includes a contact rod fixedly connected to the L-shaped pressure plate, and a slotted plate symmetrically fixed to the electric lifting plate. The slotted plate is in an inclined state, and the inner side of the slotted plate is slidably connected to the contact rod to drive the contact rod to move.

[0012] Further explanation: the germination chamber also includes a baffle assembly, which includes fixed plates symmetrically fixed to the support frame. The length of the fixed plates gradually decreases from top to bottom. A take-up roller is rotatably connected between the front and rear fixed plates. A baffle cloth is wound around the take-up roller. The end of the baffle cloth is fixedly connected to an n-type brush to block falling impurities. A spiral spring is connected between the take-up roller and the fixed plate. A collection frame is placed inside the chamber below the baffle cloth to collect impurities falling from the baffle cloth.

[0013] To further explain, the germination chamber also includes a rubber block fixed to the inside of the L-shaped pressure plate to increase the friction between the germination chamber and the seedbed.

[0014] To further explain, the germination chamber also includes a scraper fixed between the bottom of the front and rear fixed plates. The scraper contacts the baffle cloth and is used to remove impurities attached to the baffle cloth.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. First, open the closed door, then start the drive motor to drive the lead screw to rotate. The lead screw drives the support frame to move up and down through the threaded block. The up and down movement of the support frame adjusts the height of the seedbed. When the height of the support frame is adjusted to the appropriate position for seed germination, turn off the drive motor. Then, the electric lifting plate and belt conveyor assembly will move the seedbed into the chamber and onto the support frame for germination. In this way, by adjusting the height of the support frame, different microenvironments can be created to meet the germination needs of different seeds, thereby improving the seed germination effect and survival rate.

[0017] 2. With the help of the n-shaped brush, whenever the seeds are removed from the support after germination, the n-shaped brush moves to the right to remove impurities from the support. This prevents a large amount of impurities from adhering to the support and causing pollution to the room, thus ensuring a good indoor environment.

[0018] 3. With the help of the baffle cloth, whenever the n-type brush removes impurities from the support frame, the baffle cloth can block the support frame and prevent impurities falling from above, thus preventing them from falling down onto the support frame below and causing contamination, thereby further ensuring the smoothness of the support frame.

Detailed Implementation

[0032] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0033] Example: A germination chamber, please refer to [link / reference]. Figures 1-6 As shown, the device includes a chamber 1 and a control panel 2 installed on the right side of the front exterior of the chamber 1. The chamber 1 is equipped with a temperature control system, a humidity control system, a light control system, a fresh air system, and an ultraviolet disinfection system. Transparent doors 5 are symmetrically installed on the front and back of the right side of the chamber 1. An electric lifting plate 3 is installed on the right side of the chamber 1, and belt conveyor assemblies 4 are symmetrically installed on the electric lifting plate 3. When the belt conveyor assemblies 4 are in operation, they can move the seedbed to allow for loading and unloading of seedlings. A shell is fixed to the front top of the chamber 1. 6. It also includes a material clamping assembly, a support frame 8, a threaded block 82, a drive screw 83, a drive motor 84, a lead screw 85, an n-type brush 86, and a rotating assembly. The electric lifting plate 3 is equipped with a material clamping assembly. When the material clamping assembly is in operation, it can drive the seedbed to move and contact the belt conveyor assembly 4. Seven support frames 8 are vertically slidably connected at even intervals between the front and rear sides of the chamber 1. The support frames 8 can place the seedbed. Seven through holes 81 are evenly spaced on the front side of the seven support frames 8. The inner side of one of the through holes 81 in each row is fixed to... There are seven threaded blocks 82, arranged alternately from left to right. Seven drive screws 83 are evenly spaced and rotatably connected to the front side of the chamber 1. The seven drive screws 83 pass through through holes 81 and are threadedly connected to the seven threaded blocks 82 respectively. Seven drive motors 84 are evenly spaced and fixedly connected to the inside of the housing 6. The output shaft ends of the seven drive motors 84 are fixedly connected to the top ends of the seven drive screws 83 respectively. The drive motors 84 are electrically connected to the control panel 2 via a control module. The drive motors 84 are used to drive the drive screws 83 to rotate. The support frame 8 is moved by the threaded block 82, so that the height of the seedbed can be adjusted to meet the germination requirements of different seeds. An n-type brush 86 is horizontally slidably connected to the top of the support frame 8. When the n-type brush 86 moves to the right, it can remove impurities on the support frame 8. A screw 85 is rotatably connected to the front of the support frame 8. The screw 85 is threadedly connected to the front of the n-type brush 86. A rotating component is set between the chamber 1 and the support frame 8. When the rotating component is in operation, it can drive the screw 85 to rotate.

[0034] Please see Figure 2As shown, the material clamping assembly includes an electric push rod 7, a mounting block 71, and an electric lifting block 72. The electric push rod 7 is symmetrically installed on the left side of the electric lifting plate 3. The ends of the telescopic rods of the electric push rod 7 on both the front and rear sides are fixed to the mounting blocks 71. The electric lifting blocks 72 are installed on both the front and rear mounting blocks 71. The electric lifting blocks 72 can drive the seedbed to move and contact the belt conveyor assembly 4.

[0035] Please see Figure 5 and Figure 6 As shown, the drive assembly includes a stepper motor 9, a splined shaft 91, a hollow worm gear 92, a horizontal plate 93, a movable block 94, a worm wheel 95, and a cylinder 96. The worm wheel 95 and the movable block 94 are slidably connected to the left side of the lead screw 85 via a spline. The movable block 94 is located to the left of the worm wheel 95, and its right side is rotatably connected to the left side of the worm wheel 95. A cylinder 96 is fixedly connected to the front left side of the support frame 8. The end of the telescopic rod of the cylinder 96 is fixedly connected to the right side of the movable block 94. The front left side of the chamber 1 rotates... A splined shaft 91 is connected, and seven hollow worm gears 92 are evenly spaced and slidably mounted on the splined shaft 91. The hollow worm gears 92 correspond to the worm wheel 95. Seven horizontal plates 93 are evenly spaced and slidably mounted on the splined shaft 91. The top right side of the seven horizontal plates 93 is rotatably connected to the bottom end of the seven hollow worm gears 92 respectively. The top of the horizontal plates 93 is slidably connected to the bottom of the movable block 94. A stepper motor 9 is installed on the left side inside the housing 6. The output shaft end of the stepper motor 9 is fixedly connected to the top end of the splined shaft 91.

[0036] First, open the closed doors. Then, press the control panel 2 to control the drive motor 84 to rotate via the control module. The drive motor 84 drives the drive screw 83 to rotate, which in turn moves the threaded block 82 up and down. The threaded block 82 moves the support frame 8 up and down, adjusting the height of the seedbed. This allows for individual height adjustment of all seven support frames 8. Simultaneously, the up-and-down movement of the support frame 8 moves the lead screw 85 up and down, which, through the movable block 94 and the cross plate 93, moves the hollow worm gear 92 up and down. The hollow worm gear 92 slides on the splined shaft 91. When all seven support frames 8 are adjusted to the appropriate position for seed germination, turn off the drive motor 84. The drive motor 84 then stops driving the drive screw 83. When the moving screw 83 stops moving the support frame 8 via the threaded block 82, and the support frame 8 stops moving the lead screw 85 up and down, and the hollow worm gear 92 stops moving up and down, the electric lifting plate 3 can be started to move downwards to its maximum stroke. Then, the seedbed containing the seeds is placed on the electric lifting plate 3 from the right side, so that the seedbed is in contact with the belt conveyor assembly 4. The belt conveyor assembly 4 is started to reverse and move the seedbed to the left. When the seedbed is completely on the electric lifting plate 3, the belt conveyor assembly 4 is turned off. Then, the electric lifting plate 3 is started to move upwards and move the seedbed upwards. When the bottom of the seedbed is level with the support frame 8, the electric lifting plate 3 is turned off. Then, the belt conveyor assembly 4 is started to reverse and move the seedbed to the left into the chamber 1. On the support frame 8, when the seedbed moves to the left and disengages from the belt conveyor assembly 4, the seedbed stops moving to the left, the belt conveyor assembly 4 is turned off, the electric lifting block 72 is activated to move upward and insert into the hole of the seedbed, the electric lifting block 72 is turned off, the electric push rod 7 is activated, the telescopic rod of the electric push rod 7 extends and drives the mounting block 71 to move to the left, the mounting block 71 drives the seedbed to move to the left through the electric lifting block 72, so that the seedbed is completely moved onto the support frame 8, the electric push rod 7 is turned off, the electric lifting block 72 is activated to move downward and disengage from the hole of the seedbed, the electric push rod 7 is activated to drive the mounting block 71 to move to the right and reset, the mounting block 71 drives the electric lifting block 72 to move to the right and reset, then the electric lifting plate 3 is activated to move downward to its maximum stroke, and the next seedbed is placed. On the electric lifting platform 3, the seedbeds can be moved back to the support frame 8 following the above operation. Once all the seedbeds are placed on the support frame 8, the temperature, humidity, light duration, and light intensity parameters inside the chamber 1 can be set using the control panel 2. After the parameters are set, the seeds on the seedbeds can begin germination treatment. The operator can check the germination status of the seeds through the transparent door 5. In this way, by adjusting the height of the support frame 8, different microenvironments can be created to adapt to the germination needs of different seeds, thereby improving the germination effect and survival rate. When the seed germination reaches the expected standard, the transparent door 5 is opened, and the electric lifting platform 3 is moved up and down to correspond to the seedbed that needs to be removed. Then, the cylinder 96 corresponding to the seedbed that needs to be removed is activated.The extension rod of cylinder 96 shortens, causing movable block 94 to move to the right. Movable block 94 moves to the right, causing worm gear 95 to move to the right. Worm gear 95 engages with hollow worm 92. Cylinder 96 is then closed. Electric push rod 7 is activated, driving electric lifting block 72 to move to the left via mounting block 71, aligning it with the hole in the seedbed. Electric lifting block 72 moves upward and inserts into the hole in the seedbed. Then, the extension rod of electric push rod 7 shortens, driving the seedbed to the right via mounting block 71 and electric lifting block 72. When the seedbed contacts belt conveyor assembly 4, electric push rod 7 is closed. Electric lifting block 72 moves downward and disengages from the hole in the seedbed. Belt conveyor assembly 4 rotates clockwise, moving the seedbed to the right onto electric lifting plate 3. When the seedbed is fully on electric lifting plate 3, belt conveyor assembly 4 is closed. Electric lifting plate 3 moves downward, moving the seedbed downward. When the motor reaches its maximum stroke, the seedbed can be removed from the electric lifting plate 3 for subsequent planting of the germinated seeds. Simultaneously, the stepper motor 9 is activated, driving the splined shaft 91 to rotate. The splined shaft 91 drives the hollow worm gear 92 to rotate, which in turn drives the meshing worm wheel 95. The worm wheel 95 then drives the lead screw 85, which in turn moves the n-type brush 86 to the right, cleaning any remaining impurities from the support frame 8. When the n-type brush 86 reaches its maximum stroke to the right, the stepper motor 9 is activated again, driving the splined shaft 91 to rotate in the opposite direction. The splined shaft 91, through the worm wheel 95 and the hollow worm gear 92, drives the lead screw 85 to rotate in the opposite direction. The reverse rotation of the lead screw 85 then moves the n-type brush 86 to the left to reset, and the stepper motor 9 is turned off. This process prevents a large amount of impurities adhering to the support frame 8 from polluting the indoor environment, thus ensuring a clean indoor environment.

[0037] Please see Figure 7 and Figure 8As shown, the germination chamber also includes a clamping assembly installed between the electric lifting plate 3 and the mounting block 71. The clamping assembly includes an L-shaped pressure plate 10, a triggering assembly, a connecting plate 103, and a return spring 104. The connecting plate 103 is fixedly connected to the side of the mounting block 71 that is far apart from each other on both the front and rear sides. The L-shaped pressure plate 10 is slidably connected to the right side of the connecting plate 103 on both the front and rear sides. The L-shaped pressure plate 10 slides through the left side of the electric lifting plate 3. When the L-shaped pressure plate 10 moves downward and contacts the seedbed, the L-shaped pressure plate 10 can clamp and fix the seedbed. A return spring 104 is connected between the upper part of the L-shaped pressure plate 10 and the top right side of the connecting plate 103. A triggering assembly is provided between the spring 104, the electric lifting plate 3, and the L-shaped pressure plate 10. When the triggering assembly is in operation, it can drive the L-shaped pressure plate 10 to move. The triggering assembly includes a contact rod 101 and a slotted plate 102. The contact rod 101 is fixedly connected to the upper part of the L-shaped pressure plate 10 on both the front and rear sides. A slotted plate 102 is symmetrically fixed to the top left side of the electric lifting plate 3. The slot of the slotted plate 102 is in an inclined state. The inner side of the slotted plate 102 is slidably connected to the contact rod 101. When the contact rod 101 moves left and right, the slotted plate 102 can drive the contact rod 101 to move up and down.

[0038] Please see Figure 9 and Figure 10 As shown, the germination chamber also includes a material-blocking assembly installed between the support frame 8 and the n-type brush 86. The material-blocking assembly includes a fixing plate 11, a take-up roller 111, a material-blocking cloth 112, a collection frame 1121, and a spiral spring 113. The six support frames 8 from bottom to top are symmetrically fixed with fixing plates 11 on their left sides, with the length of the six fixing plates 11 gradually decreasing from top to bottom. A take-up roller 111 is rotatably connected between the left sides of the front and rear fixing plates 11. A baffle cloth 112 is wound around the top of the chamber 1. The right end of the baffle cloth 112 is fixedly connected to the left side of the n-type brush 86. The baffle cloth 112 can block falling impurities. The front and rear sides of the take-up roller 111 are connected to the front and rear fixed plates 11 respectively by spiral springs 113. A collection frame 1121 is placed at the bottom of the chamber 1. The collection frame 1121 is located below the baffle cloth 112. The collection frame 1121 can collect the impurities falling from the baffle cloth 112.

[0039] When the telescopic rod of the electric push rod 7 extends, it causes the mounting block 71 to move to the left. The mounting block 71 then causes the electric lifting block 72 to move to the left. Simultaneously, the mounting block 71 causes the connecting plate 103 to move to the left, which in turn causes the L-shaped pressure plate 10 to move to the left. The L-shaped pressure plate 10 then causes the contact rod 101 to move to the left. The slotted plate 102 causes the contact rod 101, which has moved to the left, to move downwards. The downward movement of the contact rod 101 causes the L-shaped pressure plate 10 to move downwards, compressing the return spring 104. The L-shaped pressure plate 10 then moves downwards and to the left to contact the seedbed, pressing the top of the seedbed firmly. When the electric lifting block 72 aligns with the hole in the seedbed, the electric push rod is deactivated. 7. When the mounting block 71 stops moving the connecting plate 103 to the left, the connecting plate 103 moves the L-shaped pressure plate 10 to the left. The electric lifting block 72 is then inserted into the hole in the seedbed. The electric push rod 7 is then activated, moving the mounting block 71 to the right to reset. The mounting block 71, through the electric lifting block 72, moves the seedbed to the right. Simultaneously, the mounting block 71 moves the connecting plate 103 to the right, which in turn moves the L-shaped pressure plate 10 to the right. The L-shaped pressure plate 10 moves the contact rod 101 to the right, and the slotted plate 102 moves the contact rod 101 upwards. The contact rod 101 then moves the L-shaped pressure plate 10 upwards to reset. The L-shaped pressure plate 10 moves upwards to reset and then to the right, releasing the seedbed. This prevents the seedbed from tilting and affecting the insertion of the electric lifting block 72, ensuring that the electric lifting block 72 is accurately inserted into the hole in the seedbed for pulling.

[0040] When the n-type brush 86 moves to the right to remove impurities from the support frame 8, the movement of the n-type brush 86 to the right causes the baffle cloth 112 to move to the right. The movement of the baffle cloth 112 to the right causes the take-up roller 111 to rotate forward, compressing the spiral spring 113. The baffle cloth 112 moves to the right to cover the support frame 8, and the impurities removed during the process fall downward onto the baffle cloth 112. When the n-type brush 86 moves to the left to reset, the n-type brush 86 drives the baffle cloth 112 to rotate forward. Move to the left to reset, and the baffle cloth 112 is in a relaxed state. Due to the action of the spiral spring 113, the take-up roller 111 reverses to rewind the baffle cloth 112. During the rewinding process, impurities on the baffle cloth 112 fall downwards into the collection frame 1121 due to the force of the reverse rotation. When the collection frame 1121 contains a suitable amount of impurities, the collection frame 1121 is removed from the chamber 1 to process the impurities. After all the impurities have been emptied, the collection frame 1121 is placed back into the chamber 1. In this way, the removed impurities are prevented from falling downwards onto the support frame 8 below and causing contamination, thereby further ensuring the smooth operation of the support frame 8.

[0041] Please see Figure 11 As shown, the germination chamber also includes rubber blocks 12. Rubber blocks 12 are fixed to the top left side of the L-shaped pressure plates 10 on both the front and rear sides. The rubber blocks 12 can increase the friction between the rubber blocks and the seedbed.

[0042] Please see Figure 12 As shown, the germination chamber also includes a scraper 13. The scraper 13 is fixed between the bottom of the front and rear fixed plates 11. The scraper 13 contacts the baffle cloth 112 and can remove the impurities attached to the baffle cloth 112.

[0043] When the L-shaped pressure plate 10 moves downward and to the left, it drives the rubber block 12 to move downward and to the left. The rubber block 12 comes into contact with the seedbed, and the L-shaped pressure plate 10 presses and limits the top of the seedbed through the rubber block 12. The rubber block 12 increases the friction between the seedbed and the L-shaped pressure plate 10, thus making the L-shaped pressure plate 10 press and limit the top of the seedbed more firmly, thereby improving the pressing effect on the seedbed.

[0044] When the baffle cloth 112 is reversed and rolled up, the scraper 13 can scrape off the impurities attached to the baffle cloth 112. The scraped impurities fall downward into the collection frame 1121. In this way, it can prevent impurities from being attached to the baffle cloth 112 and falling off by gravity, thereby ensuring that the impurities on the baffle cloth 112 are completely removed.

[0045] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the scope of protection of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention are all within the scope of protection claimed by the present invention.
