Description

Technical Field

[0001] This invention relates to the field of forestry breeding technology, specifically to a seed treatment device for forestry engineering. Background Technology

[0002] Forests are known as the "lungs of the earth" and occupy an important position in the ecological environment. For my country, forestry is not only an important component of agriculture, generating significant output value to support the national economy, but more importantly, it plays a regulatory role in the quality of the ecological environment and ecological balance. Its functions such as climate regulation, soil and water conservation, and biodiversity protection are important guarantees for ecological stability, and this value far exceeds its economic benefits. Therefore, strengthening forestry breeding research and improving breeding technology are crucial for promoting high-quality development of forestry and building a solid ecological barrier.

[0003] To improve seed survival rates, existing forestry breeding methods mostly employ indoor cultivation, where seeds are planted in incubators and the growth environment is optimized by artificially controlling light and irrigation conditions. However, existing indoor cultivation devices have significant drawbacks: firstly, they mostly adopt a flat structure, resulting in low utilization of seed cultivation space, occupying a large indoor volume, which is not conducive to large-scale cultivation and irrigation.

[0004] A search revealed a Chinese patent (publication number CN120677957A) disclosing a forestry breeding and cultivation device. The output end of a servo motor is equipped with a pulley, a transmission belt is fitted onto the pulley, and a connecting seat is mounted on the transmission belt. A cultivation seat is welded onto the connecting seat. A first water tank and a second water tank are mounted on an inclined frame along the movement direction of the cultivation seat. The first water tank has a drain opening, and the second water tank has an atomizing head. The inclined frame is supported by a support structure, allowing it to be tilted on the support. A transmission belt is installed inside the inclined frame, with a connecting seat connected around its circumference. This results in a two-layer arrangement of the cultivation seat at the inclined frame, increasing the number of seeds cultivated at once. The first and second water tanks on the inclined frame can spray a columnar water stream, while the second water tank can spray atomized water. Different irrigation methods can be selected according to the seed's growth stage to avoid seed damage and improve seed survival rate.

[0005] The device in the above application is distributed at an angle, and its space occupancy needs to be further reduced. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes a seed treatment device for forestry engineering.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a seed treatment device for forestry engineering, comprising a support frame, with annular conveying devices fixedly mounted on both sides of the support frame, and multiple sets of U-shaped support plates arranged in a circumferential manner on the conveyor belt of the conveying devices. Multiple fixing ears are fixedly mounted on the side walls of the support plates, and one end of each fixing ear is rotatably connected to a rotating rod. Several connecting rods are fixedly mounted on the lower surface of the rotating rod, and several breeding boxes with counterweights arranged in a ring are fixedly mounted at the bottom end of the connecting rod. Limiting components are provided on both sides of the connecting rod, each limiting component including limiting blocks fixed at both ends of the connecting rod, and anti-deflection plates are provided on both sides of each limiting block. One end of each anti-deflection plate is fixedly connected to the support frame.

[0008] By adopting the above solution, a damping shaft is added at the rotating connection between the rotating rod and the fixed ear. Combined with the counterweight design of the breeding box, the breeding box can be slowly reset when the vertical posture is adjusted, so as to avoid the seeds or soil shaking due to the impact of gravity.

[0009] Preferably, the support plate includes a middle section, with elastic telescopic rods embedded and fixed on both sides of the middle section, and a sliding section fixed at the other end of the elastic telescopic rods. A locking block is fixed on the side wall of the sliding section, and a locking seat is inserted into the outer side of the locking block. The locking seat is fixed on the conveyor belt of the conveying device. Support holes are fixed at both ends of the sliding section, and blocking holes are fixed at both ends of the middle section.

[0010] Preferably, the limiting component further includes two sets of H-shaped connecting frames located on the outside of the bracket. An electric push cylinder is fixed at the center of the connecting frame, and the driving end of the electric push cylinder is fixedly connected to the bracket. A T-shaped support member that penetrates the bracket is fixedly provided on the side wall of the connecting frame corresponding to the bracket. A support column is fixedly provided on the side wall of the support member.

[0011] Preferably, one end of the support column is provided with an annular groove, the surface of the groove is provided with a storage groove, and the inside of the storage groove is rotatably connected to an anti-detachment plate via a torsion spring shaft.

[0012] Preferably, an adjusting ring is slidably connected inside the groove, an I-shaped reset rod is provided through the surface of the support column, the reset rod passes through the support member, and an elastic element is sleeved on the surface of the reset rod.

[0013] Preferably, the side wall of the support member is fixed with a retaining plate.

[0014] Preferably, an irrigation assembly is installed on the surface of the rotating rod and the connecting rod. The irrigation assembly includes a channel that is opened inside the rotating rod and the connecting rod and communicates with it. A nozzle that communicates with the channel is fixed on the lower side wall of the connecting rod corresponding to the breeding box. An inlet end that communicates with the channel is fixed on the top of the rotating rod.

[0015] Preferably, the upper sidewall of the liquid inlet end is provided with a groove, and the irrigation assembly further includes a water inlet pipe fixed to the top of the bracket. The water inlet pipe is located on the movement trajectory of the groove, and a water pump is connected to the top of the water inlet pipe.

[0016] Preferably, the connecting rod has an outwardly recessed sealing cavity that communicates with the channel. A sealing head is slidably disposed inside the sealing cavity. A magnetic ring is fixedly disposed on the side wall of the sealing head. An elastic telescopic rod is fixedly disposed between the sealing head and the sealing cavity.

[0017] Preferably, a magnetic block is fixed to the inner side of the fixing ear, and the magnetic block is magnetically repelled by the magnetic ring and located on one side of the rotation trajectory of the magnetic ring.

[0018] Working principle: This device is based on a support frame. The two circular conveyor devices on both sides drive the support plate and the counterweight breeding box to move around. The breeding box is kept vertically stable by the counterweight and limiting components, reducing the lateral space occupation and making it suitable for large-scale cultivation. The support plate is connected to the card seat by an elastic telescopic rod. With the support component driven by the electric push cylinder, the spacing can be flexibly adjusted and the load can be transferred to protect the conveyor device. During irrigation, the breeding box moves to the top, the water inlet pipe connects with the liquid inlet end, and the repulsive force between the magnetic block and the magnetic ring causes the sealing head to temporarily close the channel to store irrigation liquid. After leaving the top, the channel opens, and the nozzle irrigates evenly, realizing efficient and automated cultivation.

[0019] This invention provides a seed treatment device for forestry engineering. It has the following beneficial effects:

[0020] 1. This invention significantly reduces the horizontal space occupied by the device by setting up breeding boxes in a vertical matrix distribution on both sides of the support, while increasing the number of seeds cultivated at one time. This solves the problem of space waste in traditional flat-lay devices and meets the needs of large-scale breeding. Moreover, the breeding boxes always maintain a vertical posture with the help of counterweights, and the soil is not easy to fall off when rotating and moving, which makes them highly stable.

[0021] 2. The support plate of this invention adopts an elastic telescopic rod and a card seat snap-fit ​​structure, which makes it easy to split and adjust the spacing according to the growth height of the seedlings; in conjunction with the support component driven by the electric push cylinder, the weight of the support plate and the breeding box can be transferred to the support column during disassembly or maintenance, avoiding long-term load-bearing wear and tear on the conveying device and extending its service life; at the same time, the anti-detachment plate, adjusting ring and other structures further ensure the safety of the operation process.

[0022] 3. The present invention uses an irrigation assembly consisting of a rotating rod, a connecting rod internal channel, and a nozzle, combined with a water inlet pipe and a water pump at the top of the support. This assembly can automatically complete irrigation when the breeding box is moved to a designated position, without the need for manual operation. Furthermore, by using the repulsive force of the magnetic block and magnetic ring in conjunction with the sealing head structure, it can avoid the problem of uneven distribution of irrigation water due to distance differences, ensuring that each breeding box receives a uniform amount of irrigation and improving the seed survival rate.

[0033] The technical solution of the present invention will now be clearly and completely described 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.

[0034] Please see the appendix Figure 1 - Appendix Figure 2 This invention provides a seed treatment device for forestry engineering, including a three-dimensional support frame 1. Annular conveying devices 2 are fixed to both sides of the support frame 1. Multiple sets of U-shaped support plates 3 are arranged around the conveyor belt of the conveying devices 2. Multiple fixing ears 9 are fixed to the side walls of the support plates 3. One end of each fixing ear 9 is rotatably connected to a rotating rod 4. Several connecting rods 5 are fixed to the lower surface of the rotating rod 4. Several breeding boxes 6 with counterweights arranged in a ring are fixed to the bottom end of the connecting rods 5. Limiting components 7 are provided on both sides of the connecting rods 5. The limiting components 7 include limiting blocks 701 fixed to both ends of the connecting rods 5. Anti-deflection plates 702 are provided on both sides of the limiting blocks 701. One end of the anti-deflection plates 702 is fixedly connected to the support frame 1. The upper and lower ends of the limiting blocks 701 are triangular, allowing them to be inserted into the two anti-deflection plates 702 during movement.

[0035] Specifically, when breeding tree species, the tree species are planted in breeding boxes 6. The breeding boxes 6, arranged in a vertical matrix from top to bottom on both sides of the support 1, significantly reduce the lateral space occupied by the device and increase the number of breeding boxes 6, facilitating large-scale cultivation. The counterweighted breeding boxes 6 apply a downward vertical pull to the connecting rod 5, ensuring the breeding boxes 6 maintain a relatively vertical distribution. When the conveying device 2 operates, the conveying support plate 3 moves the breeding boxes 6 around the conveying device 2, thereby adjusting the breeding boxes 6 to a suitable height. The breeding box 6 is designed to facilitate observation by forestry personnel and cultivation at high or low locations. When the breeding box 6 is located on both sides of the conveying device 2, the limiting block 701 is limited by the anti-deflection plate 702 to prevent the rotating rod 4 from rotating, thereby improving the stability of the breeding box 6 and preventing the breeding box 6 from tipping over due to accidental collision. When the breeding box 6 rotates to the vicinity of both ends of the conveying device 2, the limiting block 701 disengages from the anti-deflection plate 702, and the rotating rod 4 can be rotated by the gravity of the breeding box 6, so that the breeding box 6 can always maintain a vertical upward posture and prevent the soil inside the breeding box 6 from falling out.

[0036] Please see the appendix Figure 2 - Appendix Figure 3 The support plate 3 includes a middle section 301. Elastic telescopic rods 302 are embedded and fixed on both sides of the middle section 301. A sliding section 303 is fixed at the other end of the elastic telescopic rods 302. A locking block 307 is fixed on the side wall of the sliding section 303. A locking seat 304 is inserted into the outside of the locking block 307. The locking seat 304 is fixed on the conveyor belt of the conveying device 2.

[0037] Specifically, by extending the elastic telescopic rod 302, the sliding section 303 is moved to the side away from the middle section 301, so that the locking block 307 is inserted into the locking seat 304, thereby locking the support plate 3 and the conveying device 2, which makes it convenient for forestry personnel to disassemble the support plate 3 according to the expected growth height of the seedlings and adjust the spacing of the support 1.

[0038] Please see the appendix Figure 2 - Appendix Figure 4 The limiting component 7 also includes two sets of H-shaped connecting frames 703 located on the outside of the bracket 1. An electric push cylinder 704 is fixed at the center of the connecting frame 703, and the driving end of the electric push cylinder 704 is fixedly connected to the bracket 1. A T-shaped support member 705 that penetrates the bracket 1 is fixedly provided on the side wall of the connecting frame 703 corresponding to the bracket 1. A support column 706 is fixedly provided on the side wall of the support member 705. Support holes 305 are fixedly provided at both ends of the sliding section 303.

[0039] Specifically, the electric push cylinder 704 retracts, causing the support member 705 to move towards the support plate 3, so that the support column 706 is inserted into the support hole 305. The support member 705 then abuts against and pushes the sliding section 303, causing the locking block 307 to exit the locking seat 304. This transfers the gravity of the support plate 3 and the breeding box 6 connected to it to the support column 706, eliminating pressure on the conveying device 2 and thus helping to extend the service life of the conveying device 2.

[0040] Please see the appendix Figure 5 One end of the support column 706 is provided with an annular groove, and a storage groove is provided on the surface of the groove. The inside of the storage groove is rotatably connected to the anti-detachment plate 707 through a torsion spring shaft.

[0041] Specifically, when the support column 706 passes through the support hole 305, the anti-detachment plate 707 is pressed down into the storage groove through the support hole 305. After the anti-detachment plate 707 passes through the support hole 305, the anti-detachment plate 707 rotates against the side wall of the storage groove by the torque of the torsion spring shaft to keep it vertical, thereby creating a limiting effect on the middle section 301 and preventing the support column 706 from accidentally detaching from the support hole 305 and causing the support plate 3 to fall.

[0042] Please see the appendix Figure 4 - Appendix Figure 5 An adjusting ring 708 is slidably connected inside the groove. An I-shaped reset rod 711 is provided through the surface of the support column 706. The reset rod 711 passes through the support member 705. An elastic member 709 is sleeved on the surface of the reset rod 711. The two ends of the middle section 301 are respectively fixed with blocking holes 306. The blocking holes 306 are larger than the diameter of the groove and smaller than the outer diameter of the adjusting ring 708.

[0043] Specifically, when the support plate 3 needs to be conveyed, the electric push cylinder 704 retracts again, causing the front end of the support column 706 to move and pass through the blocking hole 306. The blocking hole 306 limits the adjustment ring 708, so that the adjustment ring 708 moves to the outer wall of the anti-detachment plate 707 and presses it down into the storage groove during the forward movement of the support column 706. This way, when the support column 706 exits the support hole 305, the anti-detachment plate 707 will not cause obstruction. When the electric push cylinder 704 extends, after the support column 706 exits the support hole 305, the reset rod 711 abuts against the inner wall of the bracket 1 and moves in the opposite direction, applying a blocking effect to the adjustment ring 708. During the backward movement of the support column 706, the adjustment ring 708 is pushed and misaligned with the anti-detachment plate 707, so that the anti-detachment plate 707 can be reused.

[0044] Please see the appendix Figure 2 The side wall of the support member 705 is fixed with a clamping plate 710.

[0045] Specifically, when conveying the support plate 3, the electric push cylinder 704 extends to move the clamping plate 710 towards the bracket 1 and fits against the outer wall of the sliding section 303, thereby preventing the clamping block 307 from disengaging from the clamping seat 304 during the conveying process and improving the stability of the support plate 3 during conveying.

[0046] Please see the appendix Figure 6 - Appendix Figure 7 An irrigation assembly 8 is installed on the surface of the rotating rod 4 and the connecting rod 5. The irrigation assembly 8 includes a channel that is opened inside the rotating rod 4 and the connecting rod 5 and communicates with it. A nozzle 801 that communicates with the channel is fixed on the lower side wall of the connecting rod 5 corresponding to the breeding box 6. An inlet end 802 that communicates with the channel is fixed on the top of the rotating rod 4.

[0047] Specifically, by injecting irrigation water into the inlet end 802, the water flows through the channel and into the breeding box 6 through the nozzle 801, thereby irrigating multiple tree species or seedlings.

[0048] Please see the appendix Figure 6 - Appendix Figure 7 The upper side wall of the liquid inlet end 802 is provided with a groove. The irrigation component 8 also includes a water inlet pipe 803 fixed to the top of the bracket 1. The water inlet pipe 803 is located on the moving track of the groove. A water pump is connected to the top of the water inlet pipe 803. The liquid inlet end 802 is located at the center of the rotating rod 4.

[0049] Specifically, the support plate 3 is conveyed to the top by the conveying device 2. At this time, the water inlet pipe 803 passes through the groove and enters the liquid inlet end 802. The water pump draws irrigation liquid and flows into the liquid inlet end 802 through the water inlet pipe 803 for irrigation. Repeating the above steps can automatically carry out irrigation, which helps to improve the overall irrigation efficiency of the device.

[0050] Please see the appendix Figure 8The connecting rod 5 has an outwardly recessed sealing cavity 804 that communicates with the channel. A sealing head 805 is slidably installed inside the sealing cavity 804. A magnetic ring 806 is fixed on the side wall of the sealing head 805. An elastic telescopic rod 807 is fixed between the sealing head 805 and the sealing cavity 804. A magnetic block 808 is fixed on the inner side of the fixing ear 9. The magnetic block 808 and the magnetic ring 806 are magnetically repelled and are located on one side of the rotation trajectory of the magnetic ring 806.

[0051] Specifically, when the support plate 3 is delivered to the top, gravity causes the connecting rod 5 to rotate into the fixed ear 9. Through the magnetic repulsion between the magnetic ring 806 and the magnetic block 808, the sealing head 805 slides to one side of the channel, thereby sealing and blocking the channel. This allows subsequent irrigation water to be stored in the channel first. When the support plate 3 is delivered away from the top, the magnetic ring 806 and the magnetic block 808 are misaligned, and the sealing head 805 is pulled out of the channel by the elastic telescopic rod 807. At this time, the channel is opened, allowing the water in the channel to flow into the breeding box 6 in a relatively even amount, avoiding the problem that the breeding box 6 closer to the liquid inlet 802 receives more irrigation water due to distance.

[0052] Workflow:

[0053] S1. Preliminary preparation: Plant the forestry seeds to be cultivated in the counterweight breeding box 6. According to the expected growth height of the seeds, push the sliding section 303 through the elastic telescopic rod 302 so that the locking block 307 is inserted into the locking seat 304 on the conveyor belt of the conveyor device 2, and complete the locking and fixing of the support plate 3 and the conveyor device 2. At the same time, adjust the spacing of the support plates 3 on both sides of the bracket 1 to ensure that the breeding box 6 is distributed in a vertical matrix.

[0054] S2. Position Adjustment and Stability Limitation: Start the conveyor device 2, which drives the support plate 3 and the connected breeding box 6 to move around the ring conveyor device 2, adjusting the breeding box 6 to a suitable height for cultivation or observation; when the breeding box 6 is located on both sides of the conveyor device 2, the limiting blocks 701 at both ends of the connecting rod 5 are inserted between the anti-deflection plates 702 to prevent the rotating rod 4 from rotating and to ensure the stability of the breeding box 6; when the breeding box 6 moves to the vicinity of both ends of the conveyor device 2, the limiting blocks 701 disengage from the anti-deflection plates 702, and the rotating rod 4 is rotated by the counterweight of the breeding box 6, so that the breeding box 6 always maintains a vertical posture and prevents soil from falling.

[0055] S3. Irrigation Operation: When the conveying device 2 delivers the support plate 3 to the top of the support 1, the groove of the liquid inlet end 802 precisely connects with the water inlet pipe 803 at the top of the support 1. The water pump starts to draw irrigation liquid, which flows through the water inlet pipe 803 and the liquid inlet end 802 into the connecting channel inside the rotating rod 4 and the connecting rod 5. At this time, the connecting rod 5 rotates into the fixed ear 9. The magnetic repulsion of the magnetic block 808 and the magnetic ring 806 pushes the sealing head 805 to seal the channel, and the irrigation liquid is temporarily stored in the channel. After the support plate 3 leaves the top position, the magnetic ring 806 and the magnetic block 808 are misaligned. The sealing head 805 exits the channel under the pulling force of the elastic telescopic rod 807. The temporarily stored irrigation liquid flows evenly into each breeding box 6 through the nozzle 801, completing the automated irrigation.

[0056] S4. Equipment Maintenance and Spacing Adjustment: When it is necessary to adjust the spacing of the support plate 3 or maintain the conveying device 2, activate the electric push cylinder 704 to retract, driving the support member 705 to move towards the support plate 3, so that the support column 706 is inserted into the support hole 305 of the sliding section 303, and at the same time push the sliding section 303 to make the locking block 307 disengage from the card seat 304, transferring the weight of the support plate 3 and the breeding box 6 to the support column 706; when the support column 706 is inserted, the anti-detachment plate 707 is pressed down into the receiving groove, passes through the support hole 305 and is reset under the action of the torsion spring to prevent the support plate 3 from falling; after maintenance is completed, the electric push cylinder 704 retracts again, the limit adjustment ring 708 of the stop hole 306 presses down the anti-detachment plate 707, the support column 706 disengages from the support hole 305, the electric push cylinder 704 extends to make the locking plate 710 fit against the sliding section 303, the locking block 307 is reinserted into the card seat 304, and the conveying state is restored.

[0057] S5. Cyclic Cultivation: Repeat the position adjustment, irrigation and maintenance process from S2 to S4 above, and observe and adjust regularly according to the seed growth until the seed cultivation reaches the transplanting or subsequent treatment standard.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
