Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling technology, and more specifically, to a seedling substrate particle dispensing device. Background Technology

[0002] Seedling substrate is an artificially formulated substrate material used for plant seedling cultivation. It is mainly used to replace traditional soil and provide physical support, water and nutrients for seedlings. Its core function is to optimize the plant growth environment through physical and chemical properties.

[0003] Chinese utility model patent CN220571115U discloses a seedling substrate granule dispensing machine, including a belt conveyor assembly. The belt conveyor assembly is equipped with a hopper for storing seedling substrate granules. A set of rotatable hoppers is set at the end of the hopper. A limit switch is set on the hopper to cooperate with the rotation state of the hoppers. The substrate tray passes under the hoppers and pushes the hoppers to rotate, thereby triggering the limit switch. The limit switch controls the belt conveyor assembly to work, conveying the seedling substrate granules in the hoppers and dropping them into the substrate tray through the hoppers. The dispensing is synchronized with the setting of the substrate tray, making it highly convenient to use.

[0004] However, although the above technical solutions can achieve efficient delivery of matrix particles, during the process of matrix particles moving along the hopper to the matrix disk, the matrix particles are easily scattered to the outside of the matrix disk. This not only wastes the matrix particles, but also increases the difficulty of controlling the amount of matrix particles delivered to the matrix disk. Furthermore, the above devices cannot guarantee the uniformity of the matrix particles in the matrix disk, resulting in poor practicality. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a seedling substrate particle dispensing device, which ensures that the seedling substrate particles fall completely into the container body while ensuring that the seedling substrate particles are evenly distributed in the container body through a rotating dispensing method, and the multiple dispensing structures work together to improve the working efficiency of the device.

[0006] To achieve the above objectives, this utility model provides a seedling substrate granule dispensing device, including a container body;

[0007] The feeding structure includes a workbench, a feeding body located above the workbench, and support frames installed on both sides of the feeding body along its length. The bottom end of the support frame is fixedly connected to the workbench. A feeding hopper is provided at the top of the feeding body, and several discharge pipes are provided at the bottom of the feeding body.

[0008] The conveying structure includes a fixed base mounted on the top of the worktable and a conveying component mounted on the fixed base;

[0009] The anti-spillage structure includes two fixing plates symmetrically mounted on the outer periphery of the discharge pipe, and a guide assembly and a positioning clamping assembly mounted on the fixing plates and located at the bottom of the discharge pipe, for using the anti-spillage structure to make the container body correspond to the position of the discharge pipe;

[0010] The bulk material structure includes a guide pipe rotatably installed at the lower end of the discharge pipe, a solenoid valve installed inside the guide pipe, and a rotating component installed on the discharge pipe for driving the guide pipe to rotate. A sealing gasket that fits against the top surface of the guide pipe is horizontally installed inside the discharge pipe.

[0011] Furthermore, the inside of the feed tube is provided with a feed hole, and the diameter of the feed hole on the side away from the sealing gasket gradually decreases to the end edge of the discharge tube.

[0012] Furthermore, the rotating component includes a gear ring fixed to the outer periphery of the guide pipe, a motor installed on the outer periphery of the discharge pipe, and a gear fixed to the output end of the motor, wherein the gear meshes with the gear ring.

[0013] Furthermore, the guiding assembly includes a connecting block fixed on one side of the two fixed plates and located below the discharge pipe, and a guide plate fixed on the side of the connecting block away from the fixed plates. The two guide plates are symmetrically arranged, and the distance between the two guide plates is adapted to the outer wall of the container body.

[0014] Furthermore, the guide plate has a flared section on one side of the end of the conveying component along the conveying direction.

[0015] Furthermore, the positioning and clamping assembly includes an electric push rod horizontally passing through the fixed plate, a clamping plate mounted on the piston rod of the electric push rod and located below the discharge pipe, and a sensor installed within the guide plate. The sensor is electrically connected to the electric push rod, and the electric push rod is used to push the clamping plate to clamp the container body when the sensor senses that the container body has reached a set position. Furthermore, the clamping plate is arc-shaped, and two clamping plates are symmetrically arranged. Each of the two clamping plates has a rubber pad adapted to the outer wall of the container body on its opposite side.

[0016] Furthermore, the outer periphery of the feed tube is provided with several limiting rings, and the inner wall of the discharge tube is provided with an annular groove that slides and adapts to the limiting rings.

[0017] Furthermore, the fixed base has a U-shaped cross-section, and the conveying component is a conveyor belt structure.

[0018] Furthermore, the feeding body is internally equipped with crushing and screening components.

[0019] Compared with the prior art, this utility model has the following advantages and effects:

[0020] 1. In this utility model, the seedling substrate granule dispensing device can guide the container body towards the discharge pipe through the guiding component in the dispensing structure when the container body moves with the conveying structure. When the container body and the discharge pipe are aligned, the positioning clamping component can also clamp the container body to restrict its movement, so as to maintain the precise alignment between the guide pipe and the container body during the dispensing of seedling substrate granules, effectively preventing the seedling substrate granules from scattering outside and reducing the waste of seedling substrate granules. In addition, during the dispensing of seedling substrate granules, the rotating component in the dispensing structure can drive the guide pipe to rotate, so that the seedling substrate granules can be evenly dispersed into the container body in a circular trajectory, thereby improving the uniformity of the dispensing of seedling substrate granules in the container body and further improving the practicality of the device.

[0021] 2. The seedling substrate granule dispensing device of this utility model can adjust the position of the container body on the conveying component by means of guide plates evenly arranged in the width direction of the conveying component. This allows the container bodies scattered at any position on the conveying component to gradually move to the bottom of a certain discharge pipe as the conveying component operates. Therefore, when arranging the container bodies on the conveying component, the placement position of the container bodies can be disregarded, thereby reducing the difficulty of arranging the container bodies on the conveying component and further enhancing the effectiveness of the device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Please see Figure 1-4 As shown, this utility model embodiment provides a seedling substrate granule dispensing device, including a container body 5, a dispensing structure 1, a conveying structure, a spill prevention structure 3, and a material dispersing structure 2, wherein:

[0039] The feeding structure 1 includes a workbench 11, a feeding body 13, and a support frame 12. The feeding body 13 is located above the workbench 11, and the support frame 12 is installed on both sides of the feeding body 13 along its length. The bottom end of the support frame 12 is fixedly connected to the workbench 11. The top of the feeding body 13 is provided with a feeding hopper 131, and the bottom of the feeding body 13 is provided with several discharge pipes 132. The support frame 12 is L-shaped to install the feeding body 13 on the workbench 11. The multiple discharge pipes 132 can effectively improve the feeding efficiency of seedling substrate particles.

[0040] The conveying structure includes a fixed base 4 and a conveying component 41. The fixed base 4 is installed on the top of the workbench 11, and the conveying component 41 is installed on the fixed base 4. This facilitates the use of the conveying component 41 to move the container body 5 below the feeding body 13.

[0041] The anti-spillage structure 3 includes a fixing plate 31, a guide component, and a positioning clamping component. The two fixing plates 31 are symmetrically installed on the outer periphery of the discharge pipe 132. The guide component and the positioning clamping component are both installed on the fixing plates 31 and located at the bottom of the discharge pipe 132. The guide component can guide the container body 5 to move directly below the discharge pipe 132 when the container body 5 moves, and the positioning clamping component can clamp the container body 5 when the container body 5 is directly below the discharge pipe 132, so that the seedling substrate particles flowing out of the discharge pipe 132 fall accurately into the container body 5 along the guide pipe 21, thereby preventing the waste of seedling substrate particles.

[0042] The bulk material structure 2 includes a guide pipe 21, a solenoid valve 22, and a rotating component. The guide pipe 21 is rotatably installed at the lower end of the discharge pipe 132. The solenoid valve 22 is installed inside the guide pipe 21. The rotating component is installed on the discharge pipe 132 and is used to drive the guide pipe 21 to rotate. A sealing gasket 1321 that fits the top surface of the guide pipe 21 is horizontally installed inside the discharge pipe 132. When the rotating component drives the guide pipe 21 to rotate, the seedling substrate particles falling from the guide pipe 21 can be scattered in a ring inside the container body 5, thereby ensuring that the seedling substrate particles are scattered evenly.

[0043] Please see Figure 2-3 As shown, the inside of the feed tube 21 is provided with a feed hole 211. The diameter of the feed hole 211 on the side away from the sealing gasket 1321 gradually decreases to the end edge of the discharge tube 132, so that the seedling substrate particles can flow out along the feed hole 211. The deviation design between the feed hole 211 and the axis of the feed tube 21 avoids the accumulation of seedling substrate particles in the middle of the container body 5.

[0044] Please see Figure 1-2 As shown, the rotating component includes a gear ring 23, a motor 24, and a gear 25, wherein:

[0045] The gear ring 23 is fixed on the outer periphery of the guide tube 21, the motor 24 is installed on the outer periphery of the discharge tube 132, and the gear 25 is fixed on the output end of the motor 24. The gear 25 and the gear ring 23 mesh with each other. This allows the motor 24 to drive the gear 25 to rotate, thereby enabling the gear 25 to drive the discharge tube 132 to rotate using the gear ring 23.

[0046] Please see Figure 3-4 As shown, the guide assembly includes a connecting block 32 and a guide plate 33, wherein:

[0047] The connecting block 32 is fixed on one side of the two fixed plates 31 and located below the discharge pipe 132. The guide plate 33 is fixed on the side of the connecting block 32 away from the fixed plate 31. The two guide plates 33 are symmetrically arranged, and the distance between the two guide plates 33 is adapted to the outer wall of the container body 5. This allows the scattered container body 5 to move in a straight line when it is close to the bottom of the discharge pipe 132 by using the cooperation of the two guide plates 33, thereby guiding the container body 5 to move towards the bottom of the discharge pipe 132.

[0048] Please see Figure 3-4 As shown, the guide plate 33 is provided with a flared section 331 on one side of the end of the conveying component 41 along the conveying direction; the flared section 331 can expand the range of the guide plate 33 to receive the container body 5. The arrangement of multiple sets of guide plates 33 in the width direction of the conveying component 41 can make all the container bodies 5 move in sequence and ensure that each container body 5 passes under the discharge pipe 132, avoiding the situation where there are container bodies 5 without filling seedling substrate particles.

[0049] Please see Figure 3-4 As shown, the positioning and clamping assembly includes an electric push rod 34, a clamping plate 35, and a sensor 36, wherein:

[0050] The electric actuator 34 is horizontally mounted on the fixed plate 31. The clamping plate 35 is installed on the piston rod of the electric actuator 34 and located below the discharge pipe 132. The sensor 36 is installed inside the guide plate 33 and is electrically connected to the electric actuator 34. The electric actuator 34 is used to drive the clamping plate 35 to clamp the container body 5 when the sensor 36 senses that the container body 5 has reached the set position. This facilitates limiting the movement of the container body 5 during the process of dispensing the seedling substrate particles and ensures the accurate dispensing of the seedling substrate particles.

[0051] Please see Figure 3-4 As shown, the clamping plate 35 is arc-shaped, and the two clamping plates 35 are symmetrically arranged. On the opposite side of the two clamping plates 35, there is a rubber pad 351 that is adapted to the outer wall of the container body 5. The arc-shaped clamping plate 35 and the rubber pad 351 can improve the fit between the clamping structure and the container body 5, so as to better restrict the movement of the container body 5. The rubber pad 351 can prevent the clamping plate 35 from damaging the container body 5.

[0052] Please see Figure 2-3 As shown, a number of limiting rings 212 are provided on the outer periphery of the feed tube 21, and an annular groove 1322 is provided on the inner wall of the discharge tube 132 to slide and adapt to the limiting rings 212; the movement of the limiting rings 212 in the annular groove 1322 is convenient to restrict the vertical movement of the feed tube 21, thereby improving the stability of the feed tube 21 during rotation.

[0053] Please see Figure 1-4As shown, the fixed base 4 has a U-shaped cross section, and the conveying component 41 is a conveyor belt structure; this facilitates the placement of the container body 5 on the conveyor belt, so that the conveying component 41 drives the container body 5 to move, and during this process, the protruding parts on both sides of the fixed base 4 in the width direction can prevent the container body 5 from detaching from the conveying component 41.

[0054] In this embodiment, the feeding body 13 is provided with a crushing component and a screening component (not shown in the figure); the crushing component is provided to crush the material fed into the feeding body 13, so as to reduce the particle size of the material as much as possible, and the screening component is provided to screen the material so that the material with the particle size that meets the usage requirements can move downward into the discharge pipe 132.

[0055] The working process of the above-mentioned seedling substrate granule dispensing device is as follows:

[0056] When the seedling substrate granule dispensing device is in use, the container body 5 moves along the length of the fixed seat 4 as the conveying component 41 rotates. The guide plate 33 set below the discharge pipe 132 can guide the container body 5 scattered on the conveying component 41 to move towards the bottom of each discharge pipe 132. When the container body 5 moves to the detection position of the sensor 36 on the guide plate 33, the two clamping plates 35 below the discharge pipe 132 can be clamped by operating the electric push rod 34 to restrict the movement of the container body 5 and make the container body 5 correspond to the position of the discharge pipe 132, effectively preventing the seedling substrate granules from scattering to the outside of the container body 5.

[0057] Then, the solenoid valve 22 can be opened to allow the seedling substrate particles in the feeding body 13 to move along the guide pipe 21 into the container body 5. During this process, the motor 24 can also be operated to drive the gear 25 to rotate, and the gear 25 can drive the discharge pipe 132 to rotate through the gear ring 23, so that the guide pipe 21 rotates while discharging, so that the seedling substrate particles falling in the guide pipe 21 are scattered in a ring in the container body 5, thereby ensuring that the seedling substrate particles are evenly scattered.

[0058] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
