Description

Technical Field

[0001] The present invention relates to the technical field of the preparation of plant cultivation growth substrates. Specifically, it relates to a device and a preparation method for preparing a plant cultivation growth substrate. Background Art

[0002] With the popularization of soilless cultivation technology, cultivation substrates prepared from raw materials such as peat and perlite are widely used due to advantages such as air permeability and water retention. However, existing substrate preparation equipment still has significant defects in raw material processing, ratio accuracy, and discharge control:

[0003] Separation of storage and ratio: Most existing equipment adopts a single - process mode of "directly mixing after crushing" and does not set up a separate storage unit, resulting in easy cross - contamination of raw materials and a high error rate of manual ratio, making it difficult to meet the precise requirements of different plants for the physical and chemical properties of the substrate.

[0004] Insufficient discharge control: The mixed substrate often has an excessive instantaneous discharge volume due to an unreasonable design of the discharge port. Especially in continuous production scenarios, material overflow is likely to occur, wasting raw materials and polluting the operating environment. Summary of the Invention

[0014] As a further technical solution of the present invention, the discharge port is communicated with the device main body. The discharge control mechanism includes a connecting frame fixed at the bottom of the discharge port. A through hole communicated with the discharge port is formed inside the connecting frame.

The limit switches are electrically connected to the control panel.

[0017] A preparation method of a preparation device for a plant cultivation growth substrate is as follows:

[0018] S1. First, add peat soil, coconut shells, perlite, sawdust and other related organic matters into the interior of the device body through the feed hoppers respectively. Turn on the crushing component through the control panel, so that the output end of the crushing motor drives the driving rod to rotate, and then drives the crushing teeth and a set of belt pulleys to rotate. Further drive the transmission belt and another set of belt pulleys to rotate, thereby driving the driven rod and the crushing teeth to rotate, so as to crush the raw materials. Make the crushed raw materials fall into the interior of the rotating storage mechanism along the first discharge pipe by opening the solenoid valve;

[0019] S2. Second, when the corresponding raw materials fall into the storage barrel, when crushing another type of raw material, start the rotating motor through the control panel. The output end of the rotating motor drives the rotating disk to rotate, so that the rotating disk drives the storage barrel to rotate. Detect the picture through the CCD camera. When the next storage barrel rotates to the bottom of the CCD camera, it is fed back to the control circuit board, and then control the output end of the rotating motor to stop running, so as to align the next storage barrel with the first discharge pipe, facilitating the storage of the next type of raw material;

[0020] S3. Then, after storing multiple groups of raw materials separately by crushing, set through the control panel which raw materials need to be added and mixed. Then open the flow control valve at the bottom of the raw materials, so that the corresponding raw materials are introduced into the interior of the mixing barrel through the second discharge pipe, and drive the connecting shaft and the stirring rod by the output end of the stirring motor to stir and mix multiple raw materials;

[0021] S4. Finally, when the mixing matrix is completed, drive the rotating shaft and the baffle to rotate through the output end of the adjusting motor controlled by the control panel, so as to conduct the through hole. Control the size of the material volume at the discharge port through the rotation angle of the baffle. At the same time, when the baffle is closed, under the supporting action of the upper limit block and the lower limit block, the baffle contacts the limit switch, which is then fed back to the control circuit board to control the output end of the adjusting motor to stop running, thereby closing the discharge port and completing the preparation of the growth matrix.

[0022] The working principle and beneficial effects of the present invention are as follows:

[0023] 1. Through the functions of the crushing component and the rotating storage mechanism, peat soil, coconut shells, perlite, sawdust and other related organic matters are respectively added into the interior of the device main body through the feed hopper. The crushing component is turned on through the control panel to crush the raw materials, so that the crushed raw materials fall into the interior of the rotating storage mechanism along the first discharge pipe by opening the solenoid valve. When the corresponding raw materials fall into the interior of the storage barrel, and then when another type of raw material is being crushed, the rotating motor is controlled to start through the control panel, so that the rotating disk drives the storage barrel to rotate, facilitating the storage of the next type of raw material, and solving the problems that existing equipment mostly adopts a single-process mode of "directly mixing after crushing", without setting a sub-storage unit, resulting in easy cross-contamination of raw materials, a high error rate in manual proportioning, and difficulty in meeting the precise requirements of different plants for the physical and chemical properties of the substrate.

[0024] 2. Through the function of the discharge control mechanism, when the mixing of the mixed substrate is completed, the output end of the regulating motor is driven to drive the rotating shaft and the baffle to rotate through the control panel, thereby conducting the through hole and the discharge port, and controlling the size of the discharge amount of the discharge port through the rotation angle of the baffle, solving the problem of insufficient discharge control: the mixed substrate often has too large an instantaneous discharge amount due to the unreasonable design of the discharge port, especially in continuous production scenarios, material overflow is likely to occur, wasting raw materials and polluting the operating environment.

[0025] 3. Through the functions of the support frame and the stirring mechanism, during the construction and use of the device main body, the stirring mechanism and the rotating storage mechanism can be supported, facilitating the subsequent stirring of the stirring mechanism and the rotating storage operation of the rotating storage mechanism.

[0037] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] As Figures 3 to 5 and Figures 8 to 9 shown, this embodiment proposes a preparation device for a plant cultivation growth substrate, including a device main body 1, a feed hopper 3 is arranged at the upper end of the device main body 1, a control panel 4 is arranged on the outer side of the device main body 1, a crushing assembly 5, a first discharge pipe 6, a support frame 9 and a stirring barrel 12 are arranged inside the device main body 1, a solenoid valve 7 is arranged on the outer side of the first discharge pipe 6, a CCD camera 8 is arranged inside the device main body 1, a rotary storage mechanism 10 and a stirring mechanism 11 are arranged on the outer side of the support frame 9, a discharge port 13 is arranged at the bottom of the device main body 1, and a discharge control mechanism 14 is connected to the end of the discharge port 13;

[0040] Among them, the rotary storage mechanism 10 includes a rotary disk 101. A storage barrel 102 is arranged at the upper end of the rotary disk 101. A second discharge pipe 103 is connected to the bottom of the storage barrel 102. A flow control valve 104 is installed outside the second discharge pipe 103. A rotary motor 105 is installed at the bottom of the rotary disk 101.

[0041] The rotary motor 105 is connected to the support frame 9 by bolts. A fixed connection is formed between the output end of the rotary motor 105 and the rotary disk 101. The number of storage barrels 102 is four groups and they are arranged in an array. The storage barrel 102 and the rotary disk 101 are of an integral structure. The second discharge pipe 103 is communicated with the storage barrel 102, so that raw materials can be stored, facilitating subsequent rotary addition.

[0042] The second discharge pipe 103 penetrates through the middle of the rotary disk 101. The number of flow control valves 104 is equal to the number of the second discharge pipes 103. The flow control valve 104 is electrically connected to the control panel 4, which is convenient for discharging raw materials and opening and closing the flow control valve 104. Four support legs 2 are installed at the bottom of the device main body 1.

[0043] Control buttons and a display screen are arranged outside the control panel 4. A control circuit board and a battery are arranged inside the control panel 4. The control circuit board is electrically connected to both the CCD camera 8 and the solenoid valve 7, and can control the crushing component 5 and the rotary storage mechanism 10.

[0044] The crushing component 5 includes a crushing motor 51. The output end of the crushing motor 51 is connected to a driving rod 52. A driven rod 53 is movably connected inside the device main body 1. Crushing teeth 54 and belt pulleys 56 are arranged on the outer sides of both the driving rod 52 and the driven rod 53. A transmission box 55 is connected to the outside of the device main body 1. A transmission belt 57 is arranged outside the belt pulley 56, which is convenient for driving the crushing teeth 54 to rotate and crushing the raw materials.

[0045] In this embodiment, peat soil, coconut shells, perlite, wood shavings and other related organic matters are respectively added into the inside of the device main body 1 through the feed hopper 3. The crushing component 5 is turned on through the control panel 4, so that the output end of the crushing motor 51 drives the driving rod 52 to rotate, and then drives the crushing teeth 54 and a group of belt pulleys 56 to rotate. Further drive the transmission belt 57 and another group of belt pulleys 56 to rotate, thereby driving the driven rod 53 and the crushing teeth 54 to rotate, so as to crush the raw materials. The crushed raw materials fall into the inside of the rotary storage mechanism 10 along the first discharge pipe 6 by opening the solenoid valve 7;

[0046] When the corresponding raw materials fall into the interior of the storage barrel 102, and then when another type of raw material is being crushed, the rotation motor 105 is controlled to start through the control panel 4. The output end of the rotation motor 105 drives the rotation disk 101 to rotate, causing the rotation disk 101 to drive the storage barrel 102 to rotate. The CCD camera 8 is used to detect the image. When the next group of storage barrels 102 rotates to the bottom of the CCD camera 8, it is fed back to the control circuit board, and then the output end of the rotation motor 105 is controlled to stop running, so as to align the next group of storage barrels 102 with the feeding pipe 1-6, facilitating the storage of the next type of raw material, and solving the problems that existing equipment mostly adopts a single-process mode of "directly mixing after crushing", without setting a separate storage unit, resulting in easy cross-contamination of raw materials, a high error rate in manual proportioning, and difficulty in meeting the precise requirements of different plants for the physical and chemical properties of the substrate.

[0047] Example 2

[0048] As Figures 4 to 5 shown, on the basis of Example 1, a stirring mechanism 11 is further proposed, which includes a stirring motor 111 installed at the bottom of the support frame 9, and the output end of the stirring motor 111 is fixedly connected with a connecting shaft 112. Stirring rods 113 are equidistantly installed on the outer side of the connecting shaft 112, which facilitates the mixing and stirring of various raw materials and can mix the quantitatively added raw materials as required.

[0049] The discharge port 13 is communicated with the device main body 1. The discharge control mechanism 14 includes a connecting frame 141 fixed at the bottom of the discharge port 13. A through hole 142 communicated with the discharge port 13 is opened inside the connecting frame 141. The outer side of the connecting frame 141 is bolted with an adjusting motor 143 that is electrically connected with the control panel 4, which can install the adjusting motor 143 and conduct the through hole 142 and the discharge port 13.

[0050] The output end of the adjusting motor 143 is fixedly connected with a rotating shaft 144, and the rotating shaft 144 is movably connected with the through hole 142. A baffle 145 is fixedly connected to the outer side of the rotating shaft 144, and the number of baffles 145 is two and they are symmetrically distributed. The baffle 145 is a semi-circular structure, which provides a basis for the support of the baffle 145 and subsequent blocking.

[0051] The baffle 145 is adapted to the inner side of the through hole 142. An upper limit block 146 and a lower limit block 147 are fixedly connected inside the through hole 142, and limit switches 148 are installed on the outer sides of the upper limit block 146 and the lower limit block 147. The limit switches 148 are electrically connected with the control panel 4, which facilitates the reset of the baffle 145 after rotation and plays a reminder role to avoid the situation that the through hole 142 cannot be closed due to excessive rotation of the baffle 145.

[0052] In this embodiment, after multiple groups of raw materials are respectively crushed and stored, the types of raw materials to be added and mixed are set through the control panel 4, so as to open the flow control valves 104 at the bottoms of the corresponding raw materials, enabling the corresponding raw materials to be introduced into the interior of the mixing barrel 12 through the second feed pipe 103, and driving the connecting shaft 112 and the stirring rods 113 by the output end of the stirring motor 111 to stir and mix the multiple raw materials;

[0053] Through the setting of the discharge control mechanism 14, when the mixing matrix is completely stirred, the output end of the regulating motor 143 is driven by the control panel 4 to drive the rotating shaft 144 and the baffle 145 to rotate, so as to conduct the through hole 142 and the discharge port 13, and the discharge amount of the discharge port 13 is controlled by the rotation angle of the baffle 145. Finally, when the baffle 145 is closed, under the supporting action of the upper limit block 146 and the lower limit block 147, the baffle 145 contacts the limit switch 148, and then feeds back to the control circuit board to control the output end of the regulating motor 143 to stop running, so as to close the discharge port 13 and complete the preparation of the growth matrix.

[0054] In summary, the working principle of the present invention is as follows:

[0055] When the device is in use, first, peat soil, coconut shells, perlite, wood shavings and other related organic matters are respectively added into the interior of the device main body 1 through the feed hopper 3. The crushing assembly 5 is started through the control panel 4, so that the output end of the crushing motor 51 drives the driving rod 52 to rotate, and further drives the crushing teeth 54 and a set of belt pulleys 56 to rotate, further drives the transmission belt 57 and another set of belt pulleys 56 to rotate, so as to drive the driven rod 53 and the crushing teeth 54 to rotate, thereby crushing the raw materials, and enabling the crushed raw materials to fall into the interior of the rotary storage mechanism 10 along the first feed pipe 6 by opening the solenoid valve 7;

[0056] When the corresponding raw materials fall into the interior of the storage barrel 102, when another type of raw material is crushed, the control panel 4 controls the rotary motor 105 to start. The output end of the rotary motor 105 drives the rotary disk 101 to rotate, so that the rotary disk 101 drives the storage barrel 102 to rotate. The CCD camera 8 is used for detecting the picture. When the next storage barrel 102 rotates to the bottom of the CCD camera 8, it feeds back to the control circuit board, and then controls the output end of the rotary motor 105 to stop running, so as to align the next storage barrel 102 with the first feed pipe 6, facilitating the storage of the next type of raw material;

[0057] After separately crushing and storing multiple groups of raw materials, set through the control panel 4 which raw materials need to be added and mixed, thereby opening the bottom flow control valve 104 of the raw materials, so that the corresponding raw materials are introduced into the interior of the stirring barrel 12 through the second feeding pipe 103, and drive the connecting shaft 112 and the stirring rod 113 through the output end of the stirring motor 111 to stir and mix a variety of raw materials;

[0058] When the mixing matrix is finished stirring, drive the rotating shaft 144 and the baffle 145 to rotate through the output end of the control regulating motor 143 through the control panel 4, thereby conducting the through hole 142, and control the size of the material quantity at the discharge port 13 through the rotation angle of the baffle 145. At the same time, when the baffle 145 is closed, under the supporting action of the upper limit block 146 and the lower limit block 147, the baffle 145 contacts the limit switch 148, thereby feeding back to the control circuit board, controlling the output end of the regulating motor 143 to stop running, thereby closing the discharge port 13 and completing the preparation of the growth matrix.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

Finally, when the mixing matrix is completed, drive the rotating shaft (144) and the baffle (145) to rotate by controlling the output end of the regulating motor (143) through the control panel (4), thereby opening the through hole (142), and control the amount of the material at the discharge port (13) by the rotation angle of the baffle (145). At the same time, when the baffle (145) is closed, under the supporting action of the upper limit block (146) and the lower limit block (147), the baffle (145) contacts the limit switch (148), thereby feeding back to the control circuit board to control the output end of the regulating motor (143) to stop running, thereby closing the discharge port (13) to complete the preparation of the growth matrix.
