Description

Technical Field

[0001] This invention relates to the field of seedling equipment technology, and in particular to a transmission-type multifunctional seedling system. Background Technology

[0002] Seedling raising refers to the production management process of cultivating seedlings from sowing to transplanting. In actual planting, seedling raising is the first step in the production process and a crucial link in achieving early maturity, high yield, and high profits from crops. The purpose of seedling raising is to create suitable environmental conditions for the early growth of vegetables, which is conducive to promoting early maturity and high yield, extending the growing season, and regulating market supply.

[0003] Existing multi-layered seedling raising technologies mostly use fixed seedling racks, such as the vegetable planting seedling raising device disclosed in Chinese Patent Publication No. CN 210580213 U, which has the following disadvantages:

[0004] 1. Manual handling of plug seedlings on low or high shelves is inconvenient, and the lower level of fixed multi-layer seedling racks is too low, making it difficult to move plug seedlings out due to the influence of the upper level; at the same time, moving plug seedlings on shelves higher than 1.8m requires climbing assistance, resulting in low handling efficiency.

[0005] 2. Because existing seedling racks generally use tidal fertilizer and water devices, the liquid inlet and outlet speeds are slow, which can easily lead to excessive fertilizer and water, making precise control impossible.

[0006] 3. There is a certain temperature difference between the layers of the multi-layer shelf, especially between the upper and lower layers where the growth of vegetable seedlings differs significantly. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a transmission-type multifunctional seedling system.

[0008] The technical solution adopted by the present invention is as follows: a transmission-type multifunctional seedling raising system, which includes two track assemblies arranged in parallel. The track assembly includes at least two layers of circular tracks. The circular track includes a first horizontal conveyor, a first 180° bending machine and a lifting conveyor connected in sequence. The other end of the lifting conveyor is also connected to the first horizontal conveyor of the adjacent layer through the first 180° bending machine. A second 180° bending machine is arranged between the uppermost lifting conveyors of the two track assemblies, and a transition conveyor is arranged between the lowermost first horizontal conveyors.

[0009] The transition conveyor includes a second horizontal conveyor and 90° curve machines located on both sides of the second horizontal conveyor.

[0010] A water and fertilizer device is installed between the first horizontal conveyor and the transition conveyor at the bottom of the track assembly;

[0011] The water and fertilizer device includes a mesh belt conveyor, a water tank located below the mesh belt conveyor, and a spray assembly located above the mesh belt conveyor. The mesh belt conveyor includes a mesh conveyor belt. When the plug seedlings are transported on the mesh conveyor belt, the water level in the water tank is higher than the height of the mesh conveyor belt carrying the plug seedlings. A water level balancing component is provided on one side of the water tank. The water level balancing component is used to maintain the water level in the water tank at a constant value according to a preset value.

[0012] The spray assembly includes a spray pipe and spray heads evenly arranged on the spray pipe. The spray heads are located in the area above the water storage area of ​​the water tank, and a control valve is connected to one end of the spray pipe.

[0013] The mesh belt conveyor also includes a frame, with a main roller and an auxiliary roller at each end of the frame. The main roller is connected to a drive assembly. A first steering roller, a second steering roller, a third steering roller, and a fourth steering roller are sequentially arranged between the main roller and the auxiliary roller. The main roller, the first steering roller, the fourth steering roller, and the auxiliary roller are at the same horizontal height. The second steering roller and the third steering roller are at the same horizontal height. The second steering roller is obliquely downward relative to the first steering roller towards the center of the bottom of the water tank, and the third steering roller is obliquely downward relative to the fourth steering roller towards the center of the bottom of the water tank. The mesh conveyor belt is tensioned on each roller. Limiting blocks are provided on the inner walls of both sides of the frame at the upper and lower positions corresponding to the first steering roller, the second steering roller, the third steering roller, and the fourth steering roller. The limiting blocks are used to ensure that the mesh conveyor belt fits the rollers during transport.

[0014] The upper end face of the mesh conveyor belt on the second and third steering roller shafts is 20mm-30mm lower than the water level in the tank.

[0015] The water level balancing component includes a water level detector installed on the inner wall of the water tank, an outlet pipe, an inlet pipe and a drain pipe installed on one side of the water tank, and a water tank installed on one side of the water tank. The water tank is connected to the outlet pipe, the inlet pipe and the spray pipe respectively, and each pipe is equipped with a control valve and a pump body.

[0016] The lifting conveyor includes a second horizontal conveyor and a ramp conveyor, wherein the ramp conveyor has a slope of no more than 15°.

[0017] Several supports are evenly arranged on both sides of the circular track on each layer, and an mounting plate is provided on the top of the supports, with LED fill lights provided on the mounting plate.

[0018] A fan is mounted on the bracket and / or mounting plate.

[0019] The first horizontal conveyor, the first 180° curve conveyor, the lifting conveyor, the second horizontal conveyor, and the 90° curve conveyor are all equipped with brush assemblies, which are used to clean debris from the surface of the conveyor belt.

[0020] It also includes an electrical control box and a frequency converter. The first horizontal transmission machine, the first 180° curve machine, the lifting transmission machine, the second horizontal transmission machine, the 90° curve machine, and the mesh belt transmission machine are all connected to the electrical control box.

[0021] The time it takes for the track assembly to transport the seedlings from the trays for one cycle can be preset and adjusted by the frequency converter and the electrical control box.

[0022] The beneficial effects of this invention are as follows: 1. This invention realizes the cyclical transport of plug seedlings on the track assembly through the layout and connection of various transmission machines. The transitional transmission machine can realize the loading and unloading of all plug seedlings, solving the problem of inconvenient handling of plug seedlings in traditional seedbed frames. At the same time, the bottom 90° bending machine can also be matched with other mobile transmission machines to transport plug seedlings to designated positions, greatly improving the handling efficiency of plug seedlings.

[0023] 2. The present invention is equipped with a water and fertilizer device at the bottom layer, which can select the spray water supply method and the bottom suction water supply method according to the needs of seedling cultivation. By controlling the transmission speed of the seedlings in the plug tray, the water and fertilizer supply can be controlled more precisely.

[0024] 3. This invention achieves the interchange of positions of seedlings in the upper and lower shelves through a circulating track assembly, overcoming the influence of temperature differences between different shelves on the growth rate of vegetable seedlings. Attached Figure Description

Therefore, the directional and positional terms used are for illustrating and understanding this invention, and not for limiting the scope of protection of this invention.

[0035] like Figures 1 to 5 The image shows one embodiment of the present invention:

[0036] A transmission-type multifunctional seedling raising system includes two parallel track assemblies 1 and a control system. The distance between the two track assemblies 1 is 400mm-600mm for easy maintenance and repair. Each track assembly 1 includes at least two layers of circular tracks 2. In this embodiment, each circular track 2 is configured with five layers to make reasonable use of space. Each circular track 2 includes a first horizontal conveyor 21, a first 180° bending machine 22, and a lifting conveyor 23 connected in sequence. The other end of the lifting conveyor 23 is also connected to the first horizontal conveyor 21 of the adjacent layer through the first 180° bending machine 22. A second 180° bending machine 3 is provided between the uppermost lifting conveyors 23 of the two track assemblies 1, and a transition conveyor 4 is provided between the lowermost first horizontal conveyors 21. The transition conveyor 4 includes a second horizontal conveyor 41 and a... 90° bending machines 42 are set on both sides of the second horizontal conveyor 41; all kinds of conveyors and bending machines adopt existing technology to ensure stable transmission and can be freely spliced. They can be directly customized according to the required specifications, such as belt width of 560mm-600mm; the transmission length of the first horizontal conveyor 21 and the lifting conveyor 23 is 7000mm-8000mm; the surface of the conveyor belt has a certain static friction to ensure that it will not slip or tip over even when there is water; the lifting conveyor 23 is a conveyor with a certain slope, or it can be another solution, that is, the lifting conveyor 23 includes the second horizontal conveyor 41 and the inclined conveyor, first a horizontal conveyor and then the inclined conveyor, so that the seedlings in the plug tray can be transmitted on the horizontal conveyor as much as possible, making it easier to control the transmission speed and the transmission more stable, and the slope of the inclined conveyor does not exceed 15°. In addition, the first 180° bending machine 22 is a bending machine without an inner diameter, requiring the seedlings in the trays to rotate and pass through in an orderly manner while ensuring that the supply speed is not lower than that of a horizontal straight conveyor belt; the second 180° bending machine 3 is a bending machine with an inner diameter and a larger size than the first 180° bending machine 22. Thus, through the layout and connection of various conveyors, and under the unified control of the control system, the seedlings in the trays are circulated and transported on the track assembly. The transition conveyor can realize the loading and unloading of all seedlings in the trays, solving the problem of inconvenient handling of seedlings in the trays on traditional seedbed frames; at the same time, the bottom 90° bending machine 42 can also be matched with other mobile conveyors to transport the seedlings in the trays to designated locations, greatly improving the handling efficiency of the seedlings in the trays, and also overcoming the influence of temperature differences between different shelves on the growth rate of vegetable seedlings.

[0037] A water and fertilizer device 5 is installed between the lowest horizontal conveyor 21 and the transition conveyor 4 of the track assembly 1. The water and fertilizer device 5 includes a mesh belt conveyor 51, a water tank 52 located below the mesh belt conveyor 51, and a spray assembly 53 located above the mesh belt conveyor 51. The mesh belt conveyor 51 includes a mesh conveyor belt 511, which is generally made of metal mesh. When the seedlings are transported on the mesh conveyor belt 511, the water level in the water tank 52 is higher than the height of the mesh conveyor belt 511 carrying the seedlings. A water level balancing component is installed on one side of the water tank 52. The water level balancing component is used to maintain the water level in the water tank 52 at a preset value; the spray component 53 includes a spray pipe 531 and spray heads 532 evenly arranged on the spray pipe 531. The spray heads 532 are located in the area above the water storage area of ​​the water tank 52. One end of the spray pipe 531 is connected to a control valve and a water pump, so as to control the spray volume and spray speed of the spray heads 532. By equipping the water and fertilizer device, the spray water supply method and the bottom suction water supply method can be selected according to the seedling needs. By controlling the transmission speed of the seedlings in the plug tray, the water and fertilizer supply can be controlled more precisely.

[0038] like Figure 4 As shown, the mesh belt conveyor 51 also includes a frame 512. A main roller shaft 513 and an auxiliary roller shaft 514 are respectively arranged at both ends of the frame 512. The main roller shaft 513 is connected to a drive assembly. A first steering roller shaft 501, a second steering roller shaft 502, a third steering roller shaft 503, and a fourth steering roller shaft 504 are sequentially arranged between the main roller shaft 513 and the auxiliary roller shaft 514. The main roller shaft 513, the first steering roller shaft 501, the fourth steering roller shaft 504, and the auxiliary roller shaft 514 are at the same horizontal height. The second steering roller shaft 502 and the third steering roller shaft 503 are at the same horizontal height. The first steering roller shaft 501 is angled downwards towards the center of the bottom of the water tank 52, and the third steering roller shaft 503 is angled downwards relative to the fourth steering roller shaft 504 towards the center of the bottom of the water tank 52. The mesh conveyor belt 511 is tensioned on each roller shaft. Limiting blocks 54 are provided on the inner walls of both sides of the frame 512 at the upper and lower positions corresponding to the first steering roller shaft 501, the second steering roller shaft 502, the third steering roller shaft 503, and the fourth steering roller shaft 504. The limiting blocks 54 are used to ensure that the mesh conveyor belt 511 fits against each roller shaft for conveying, ensuring that the middle part of the mesh conveyor belt 511 can sink to a certain depth in the water, so that the seedlings in the plug trays can absorb water from the bottom. Several supporting roller shafts can also be provided between the second steering roller shaft 502 and the third steering roller shaft 503 to prevent the middle part of the mesh conveyor belt 511 from sagging, which would make it difficult to control the immersion depth of the seedlings in the plug trays.

[0039] Specifically, the upper end face of the mesh conveyor belt 511 on the second steering roller shaft 502 and the third steering roller shaft 503 is 20mm-30mm lower than the water level in the water tank 52.

[0040] The water level balancing component includes a water level detector installed on the inner wall of the water tank 52, an outlet pipe, an inlet pipe, and a drain pipe installed on one side of the water tank 52. A water tank is installed on one side of the water tank 52. The water tank is connected to the outlet pipe, the inlet pipe, and the spray pipe 531. Each pipe is equipped with a control valve and a pump. The control valve is preferably a solenoid valve in conjunction with the control system to control the direction, flow rate, and speed of the medium in each pipe. At the same time, a suitable fertilizer solution can be prepared in the water tank. The control system controls the corresponding control valve and pump to work. Depending on the different seedling trays, spray watering or bottom suction watering can be selected. When the water level detector detects that the water level in the water tank 52 does not match the preset value, the water level can be controlled through the water tank and the external fertilizer system.

[0041] Each layer of the circular track 2 has several supports 201 evenly arranged on both sides, and each support 201 has an mounting plate 202 on top. The mounting plate 202 is equipped with an LED supplementary light 203, which can meet the light requirements of the seedling stage.

[0042] Fans are installed on the bracket 201 and / or mounting plate 202 to ensure air circulation in each layer of the seedling rack.

[0043] The first horizontal conveyor 21, the first 180° bending machine 22, the lifting conveyor 23, the second horizontal conveyor 41, and the 90° bending machine 42 are all equipped with brush assemblies. The brush assemblies are used to clean debris from the surface of the conveyor belt. Specifically, the brushes include hard bristles and wiper blades, and together with a blowing mechanism, they clean up the waste and water remaining on the belt.

[0044] The control system includes an electrical control box and a frequency converter. The first horizontal conveyor 21, the first 180° bending machine 22, the lifting conveyor 23, the second horizontal conveyor 41, the 90° bending machine 42, and the mesh belt conveyor 51 are all connected to the electrical control box. Various control valves, pumps, LED supplementary lights 203, etc., are also controlled by the control system. The time it takes for the track assembly 1 to transport the seedlings in the trays for one cycle can be preset and adjusted by the frequency converter and the electrical control box.

[0045] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
