Description

Technical Field

[0001] This utility model relates to the field of seedling tray substrate filling technology, specifically to a seedling tray substrate filling device. Background Technology

[0002] Seedling trays are a common tool in factory-scale seedling production processes. The tray seedling technology uses a mixture of materials such as peat moss, wood fiber, and vermiculite as the seedbed. This substrate is filled into the seedling trays, and then the trays are precisely sown using mechanized methods, resulting in one seed per cell and a single seedling emergence – a modern seedling production technology. Traditionally, filling the seedling trays with the substrate was done manually, which was cumbersome, inefficient, and time-consuming.

[0003] In the prior art, mechanical filling devices are commonly used for substrate filling. For example, patent number CN202220268145.X discloses a filling device for seedling substrate, which involves setting up a funnel containing substrate above a conveyor belt and connecting a discharge channel at the lower end of the funnel. The seedling trays are conveyed by the conveyor belt and filled with substrate through the lower end of the discharge channel. However, because the substrate contains lightweight materials such as peat moss and wood fiber, as well as a certain amount of moisture, the substrate is easily clumped on the side wall of the funnel or discharge channel after being piled up and squeezed in the funnel during the filling process. This results in uneven feeding and can easily lead to insufficient or uneven filling of the substrate in the seedling trays. Utility Model Content

[0004] In view of this, it is necessary to provide a substrate filling device for seedling trays to solve the technical problem in the prior art that the substrate is not smoothly fed, resulting in insufficient or uneven substrate filling in the seedling trays.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A seedling tray substrate filling device includes a tray conveying device arranged in parallel for conveying seedling trays and a substrate filling device mounted on the tray conveying device. The substrate filling device includes a substrate carrying box, a spiral pusher, and a substrate loosening device. The substrate carrying box is mounted directly above the tray conveying device. Multiple substrate troughs are arranged horizontally side by side on the lower end face of the substrate carrying box. The substrate troughs are parallel to the conveying direction of the tray conveying device. A discharge channel is provided at the same end of each substrate trough, and the discharge channel is directly opposite the conveying surface of the tray conveying device. Multiple spiral pushers are arranged horizontally in each substrate trough and extend along the substrate trough towards the discharge channel. The substrate loosening device is located above the substrate troughs in the substrate carrying box to loosen the substrate entering the substrate carrying box, so that the substrate falls loosely into the substrate troughs. The spiral pusher pushes the substrate in each substrate trough towards the discharge channel, so that the substrate fills the seedling trays conveyed by the tray conveying device.

[0007] Preferably, the substrate loosening device includes a stirring motor and at least one set of stirring shafts. The stirring shafts are arranged horizontally above multiple substrate troughs in the substrate support box, perpendicular to the substrate troughs, and close to the discharge channel. The stirring motor is arranged on the outer wall of the substrate support box, connected to the stirring shafts, and drives the stirring shafts to rotate, so as to loosen the substrate in the substrate support box.

[0008] Preferably, each discharge channel is provided with a flow regulating plate at its opening. The upper end of the flow regulating plate is hinged to the side wall of the back of the discharge channel, and the lower end of the flow regulating plate hangs freely in the discharge channel and can rotate freely along the back of the discharge channel toward the front of the discharge channel. An adjusting groove is transversely provided through the side wall of all discharge channels. One end of the adjusting groove is close to the back of the discharge channel, and the other end extends toward the front of the discharge channel. A limiting rod is transversely provided in all adjusting grooves. The limiting rod is perpendicular to the substrate tank and blocks the back of all flow regulating plates. Locking bolts are provided at both ends of the limiting rod to lock the limiting rod in the adjusting groove. By pushing the limiting rod along the adjusting groove toward the front of the discharge channel, the lower end of all flow regulating plates can rotate toward the front of the discharge channel to narrow the opening of the discharge channel.

[0009] Preferably, a substrate smoothing mechanism is also provided directly above the seedling tray conveying device. The substrate smoothing mechanism includes a scraper and two fixed supports. The fixed supports are arranged opposite each other on both sides of the seedling tray conveying device and are located in front of the discharge channel. The two ends of the scraper are respectively set on the two fixed supports. The two fixed supports are horizontally mounted directly above the conveying surface of the seedling tray conveying device. After the seedling trays are filled with substrate, they are conveyed to the scraper direction through the seedling tray conveying device so that the substrate on the upper surface of the seedling tray is smoothed by the scraper.

[0010] Preferably, each of the two fixed supports has a vertically formed groove, and an adjusting handle is provided on each of the two grooves. The two ends of the scraper are fixed to the grooves of the two fixed supports by the adjusting handles, and can move up and down along the grooves and lock to adjust the height of the scraper.

[0011] Preferably, the seedling tray conveying device has stop bars on both sides to limit the offset of the seedling tray, and the stop bars extend along the conveying direction of the seedling tray conveying device.

[0012] Preferably, each of the substrate tanks is provided with a V-shaped guide plate at the end of the discharge channel. The tip of the V-shaped guide plate faces the auger pusher. One of the inclined surfaces of the V-shaped guide plate extends upward toward the discharge channel, and the other inclined surface extends downward toward the discharge channel. The two inclined surfaces of the V-shaped guide plate divide the substrate pushed by the auger pusher toward the discharge channel into two parts. The substrate near the inclined surface of the V-shaped guide plate is guided toward the stirring shaft, and the substrate near the lower inclined surface of the V-shaped guide plate is guided into the discharge channel.

[0013] As can be seen from the above technical solution, this application provides a seedling tray substrate filling device, including a tray conveying device and a substrate filling device. The substrate filling device includes a substrate carrying box, a spiral pusher, and a substrate loosening device. The substrate carrying box is mounted directly above the tray conveying device. Multiple substrate troughs are arranged horizontally side-by-side on the lower end face of the substrate carrying box. The substrate troughs are parallel to the conveying direction of the tray conveying device. A discharge channel is provided at the same end of each substrate trough, and the discharge channel faces the conveying surface of the tray conveying device. Multiple spiral pushers are included. Each substrate is laid horizontally in its own substrate trough and extends towards the discharge channel. The substrate loosening device is positioned above the substrate trough inside the substrate carrier box. This device loosens the substrate entering the carrier box, preventing it from clumping due to accumulation and compression. This ensures the substrate flows smoothly into the substrate trough. Furthermore, the spiral pusher actively pushes the substrate from the discharge channel into the seedling trays, ensuring the trays are fully filled and preventing insufficient or uneven substrate filling.

Detailed Implementation

[0021] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5This utility model provides a seedling tray substrate filling device, including a tray conveying device 10 arranged in parallel for conveying seedling trays and a substrate filling device 20 mounted on the tray conveying device 10. The substrate filling device 20 includes a substrate carrying box 201, a spiral pusher 202, and a substrate loosening device 203. The substrate carrying box 201 is mounted directly above the tray conveying device 10. Multiple substrate troughs 204 are arranged horizontally side by side on the lower end face of the substrate carrying box 201. The substrate troughs 204 are parallel to the conveying direction of the tray conveying device 10. A discharge channel is provided at the same end of each substrate trough 204. 205, the discharge channel 205 is arranged longitudinally, and the channel opening of the discharge channel 205 is directly opposite the conveying surface of the seedling tray conveying device 10. The seedling tray conveying device 10 is a belt conveyor used to convey seedling trays through the channel opening of the discharge channel 205. The substrate filled in the substrate carrier box 201 enters the substrate trough 204 and can be discharged from the discharge channel 205 to the seedling trays conveyed by the conveying surface of the seedling tray conveying device 10. There are multiple spiral pushers 202, which lie horizontally in each substrate trough 204 and extend along the substrate trough 204 towards the discharge channel 205. The two ends of the spiral pusher 202 are rotatably mounted on the shaft ends. On the side wall of the substrate carrier box 201, one shaft end of a spiral pusher 202 extends out of the outer wall of the substrate carrier box 201. A drive motor 211 is installed on the outer wall of the spiral pusher 202 extending out of the substrate carrier box 201 to drive the spiral pusher 202 to rotate. The output shaft of the drive motor 211 is connected in series or in parallel with the shaft ends of each spiral pusher 202 extending out of the substrate carrier box 201 via a belt or chain, so that the drive motor 211 simultaneously drives each spiral pusher 202 to rotate synchronously, conveying the substrate towards the discharge channel 205. After the substrate is discharged from the outlet of the discharge channel 205, it fills the conveying device. In the seedling trays being transported, the substrate loosening device 203 is installed inside the substrate carrying box 201. The substrate loosening device 203 includes a stirring motor 2031 and at least one set of stirring shafts 2032. The stirring shafts 2032 are horizontally arranged above the multiple substrate troughs 204 inside the substrate carrying box 201, perpendicular to the substrate troughs 204, and close to the discharge channel 205. The stirring motor 2031 is installed on the outer wall of the substrate carrying box 201, connected to the stirring shafts 2032, and drives the stirring shafts 2032 to rotate inside the substrate carrying box 201 to loosen the substrate inside the substrate carrying box 201, so that the substrate falls loosely into each substrate trough 204.

[0023] Please refer to Figure 5Preferably, in this embodiment, multiple sets of conveying and stirring shafts 2032 are arranged side-by-side along the length of the substrate tank 204. Each set of stirring shafts 2032 has multiple stirring grips spaced apart. One end of each stirring shaft 2032 extends out of the side wall of the substrate support box 201 and is connected in series or parallel to the shaft end of the stirring motor 2031 via a belt or chain. The stirring motor 2031 drives each set of stirring shafts 2032 to rotate synchronously, loosening the substrate within the substrate support box 201. Furthermore, the multiple sets of stirring shafts 2032 positioned above the substrate tank 204 provide support for the substrate within the substrate support box 201, reducing the pressure of the substrate filling the substrate support box 201 on the substrate tank 204, thereby keeping the substrate entering the substrate tank 204 in a loose state.

[0024] Please refer to Figure 3 , Figure 4 and Figure 6 Furthermore, to control the size of the outlet and the discharge volume of the discharge channel 205 to adapt to substrate filling of seedling trays of different sizes, a flow regulating plate 206 is provided at the outlet of each discharge channel 205. The upper end of the flow regulating plate 206 is hinged to the side wall of the back of the discharge channel 205, and the lower end of the flow regulating plate 206 hangs freely in the discharge channel 205 and can rotate freely from the back of the discharge channel 205 to the front of the discharge channel 205 to narrow the outlet. An adjusting groove 207 is transversely provided through the side wall of the discharge channel 205, penetrating all the side walls of the discharge channels 205. One end of the adjusting groove 207 is close to the back of the discharge channel 205, and the other end extends towards the front of the discharge channel 205. A limiting rod 2 is transversely provided in all the adjusting grooves 207. 08. The limiting rod 208 is perpendicular to the substrate tank 204 and blocks the back of all flow regulating plates 206, and is close to the lower end of the flow regulating plates 206. Locking bolts 209 are respectively provided at both ends of the limiting rod 208. The limiting rod 208 is locked in the regulating groove 207 by the locking bolts 209. When adjusting the size of the discharge channel 205, the locking bolts 209 are loosened, and the limiting rod 208 is pushed to move along the regulating groove 207 towards the front of the discharge channel 205. The limiting rod 208 is used to simultaneously push the flow regulating plates 206 on each discharge channel 205 towards the front of the discharge channel 205. By moving the limiting rod 208 along the regulating groove 207 towards the front of the discharge channel 205, the lower end of all flow regulating plates 206 can be pushed to rotate simultaneously towards the front of the discharge channel 205 to reduce the size of the discharge channel 205. When it is necessary to increase the opening of the discharge channel 205, simply move the limit rod 208 in the opposite direction.

[0025] Please continue reading. Figure 2 Furthermore, a substrate smoothing mechanism 30 is also provided directly above the seedling tray conveying device 10. The substrate smoothing mechanism 30 includes a scraper 301 and a fixed bracket 302. There are two fixed brackets 302, which are arranged vertically on both sides of the seedling tray conveying device 10 and located in front of the discharge channel 205, that is, on the side where the seedling tray is output after being filled with substrate. The two ends of the scraper 301 are respectively set on the two fixed brackets 302. The two fixed brackets 302 are horizontally mounted directly above the conveying surface of the seedling tray conveying device 10. After being filled with substrate, the seedling tray is conveyed by the seedling tray conveying device 10 towards the scraper 301 so that the scraper 301 can smooth the excess substrate on the upper surface of the seedling tray. To enable the scraper 301 to be height-adjustable for leveling seedling trays of different heights, vertical grooves 303 are provided on each of the two fixed supports 302. Each groove 303 contains a locking block that can slide up and down along it. Adjusting handles 304 are provided on each groove 303, passing through both ends of the scraper 301 and threadedly engaging with the locking blocks in the grooves 303. Rotating the adjusting handles 304 clamps the scraper 301 onto the grooves 303. To adjust the height of the scraper 301, release the two adjusting handles 304 and pull them to move the baffle along the height direction of the adjusting handles 304 and lock it in place.

[0026] Please continue reading. Figure 2 Furthermore, the seedling tray conveying device 10 has stop bars 40 on both sides to limit the offset of the seedling tray. The stop bars 40 extend along the conveying direction of the seedling tray conveying device 10 and are parallel to each other. The two stop bars 40 are used to block the seedling trays being conveyed on both sides to prevent the seedling trays from shifting position during the conveying process.

[0027] Please refer to it again. Figure 5Furthermore, each of the substrate tanks 204 is provided with a V-shaped guide plate 210 at the end of the discharge channel 205. The tip of the V-shaped guide plate 210 faces the spiral pusher 202. One of the inclined surfaces of the V-shaped guide plate 210 extends upward toward the discharge channel 205, and the other inclined surface extends downward toward the discharge channel 205. The two inclined surfaces of the V-shaped guide plate 210 divide the substrate pushed by the spiral pusher 202 toward the discharge channel 205 into two parts. The substrate near the upper inclined surface of the V-shaped guide plate 210 is guided toward the stirring shaft 2032, and the substrate near the lower inclined surface of the V-shaped guide plate 210 is guided into the discharge channel 205. The V-shaped guide plate 210 guides the substrate, allowing the substrate near the lower slope of the V-shaped guide plate 210 to be smoothly discharged from the discharge channel 205, while the substrate near the upper slope of the V-shaped guide plate 210 is guided back towards the stirring shaft 2032 for further stirring and loosening. This prevents the substrate pushed by the spiral pusher 202 from accumulating at the end of the discharge channel 205 in the substrate tank 204, and also prevents the substrate from forming clumps after being pushed and squeezed by the spiral pusher 202.

[0028] During the filling process of the seedling tray substrate filling device, the substrate loosening device 203 can loosen the substrate entering the substrate carrying box 201, avoiding the phenomenon of substrate clumping after being piled up and squeezed in the substrate carrying box 201, ensuring that the substrate smoothly enters the substrate trough 204, and the substrate is actively pushed into the seedling tray through the discharge channel 205 by the spiral pusher 202, so that the seedling tray is fully filled and the phenomenon of insufficient or uneven substrate filling in the seedling tray is avoided.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
