Description

Technical Field

[0001] The present invention relates to the technical field of seedling transport vehicles, in particular to a seedling transport vehicle applicable to a mobile seedbed. Background Art

[0002] As an important seedling raising tool in modern agriculture, the seedling transport vehicle applicable to a mobile seedbed is designed to improve the efficiency of seedling transportation and reduce the labor intensity of manual work. At present, there is no small seedling handling equipment suitable for mobile seedbeds in seedling production, and most seedling factories use manual handling.

[0003] At present, firstly, since the width of the seedbed may vary according to planting requirements, and the existing transport vehicles cannot adapt to mobile guide rails of different widths, which limits their scope of use and reduces flexibility. Secondly, the functions of the transport vehicles are relatively single, limited to the transportation of seedlings, lacking other auxiliary functions. For example, in a rainy and humid environment, water exudation occurs on the leaves of seedlings, or water droplets are formed on the leaves due to sprinkler irrigation operations and the evaporation is slow, increasing the risk of disease occurrence. Blowing can promote water loss, keep the leaf surface dry, and reduce the occurrence of diseases. In addition, before the seedlings are out of the nursery, it is necessary to strengthen the seedlings by hardening them. Blowing and mechanical stimulation can promote the contact morphogenesis of plants on the basis of hardening the seedlings by means of environmental and water and fertilizer control, so as to improve the maturity and resistance of the seedlings, clean pests, and reduce the occurrence of insect pests.

[0004] Therefore, a seedling transport vehicle applicable to a mobile seedbed is proposed. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1-4 , the present invention provides a technical solution: a seedling transfer vehicle applicable to a mobile seedbed, including a transfer vehicle main body 1 and universal wheels 2 fixed at the four corners of the bottom of the transfer vehicle main body 1 to facilitate the transfer of the vehicle body. A matching guide rail 3 is provided below the universal wheels 2. The bottom of the transfer vehicle main body 1 is movably connected to a replacement seat 7 relatively. A brush 8 is threadedly connected inside the front replacement seat 7 through a first bolt. A lifting mechanism is provided above the replacement seat 7 and fixed on the transfer vehicle main body 1. A plurality of nozzles 24 are detachably installed inside the rear replacement seat 7. The air inlet ends of the plurality of nozzles 24 are commonly connected to a blower 18 for cleaning pests and water stains on the surface of the seedlings. The blower 18 is fixed on the transfer vehicle main body 1. An adjusting mechanism is provided at the bottom of the transfer vehicle main body 1. The adjusting structure is used to control the two universal wheels 2 to be applicable to guide rails 3 of different widths. By rotating the bidirectional screw 14 in the adjusting mechanism, the two adjusting seats 12 and the universal wheels 2 connected thereto are driven to move in opposite or opposite directions, so as to be applicable to the guide rails 3 on seedbeds of different widths for use. At the same time, during the transfer process, the blower 18 can blow off pests or water stains on the surface of the seedlings to prevent pests. Secondly, in cooperation with the electric push rod 11 in the lifting mechanism to push the connecting rod 9 up and down, the two swing arms 5 on the rod wall are driven to pull the brush 8 to move up and down together, so as to sort out the messy seedlings neatly, thereby improving the functionality of the transfer vehicle main body 1.

[0023] In this embodiment, the lifting mechanism includes rotating seats 4 relatively installed at the bottom of the transfer vehicle main body 1. Two swing arms 5 are rotatably installed inside each of the two rotating seats 4. A corresponding set of swing arms 5 are respectively installed on the corresponding replacement seats 7. A connecting rod 9 is slidably connected inside a corresponding set of swing arms 5. One ends of the two connecting rods 9 are commonly rotatably connected to a lifting plate 26. The lifting mechanism further includes a connecting seat 10 installed on the rod wall of the front connecting rod 9. An electric push rod 11 is rotatably connected inside the connecting seat 10. The electric push rod 11 is installed on the transfer vehicle main body 1 to control the electric push rod 11 to contract to drive the two connecting rods 9 to move up and down together.

[0024] In this embodiment, the output end of the blower 18 is connected to a distribution box 22. A plurality of intake hoses 23 are installed on one side of the distribution box 22. The bottom ends of the plurality of intake hoses 23 are respectively connected to the upper ends of the corresponding nozzles 24 in a penetrating manner. The outer walls of the plurality of nozzles 24 are all installed with movable seats 25. The plurality of movable seats 25 are all slidably installed inside the rear replacement seat 7. A plurality of second bolts for fixing the installation positions of the corresponding movable seats 25 are threadedly connected to the top of the rear replacement seat 7, enabling the plurality of nozzles 24 to be adjusted to be suitable for drying seedbeds of different widths. While the electric push rod 11 in the lifting mechanism controls the swing of the swing arm 5 up and down, the lifting plate 26 is coordinated to drive the connecting rod 9 at the rear to pull the swing arm 5 at the rear to swing up and down together, thereby driving the plurality of nozzles 24 connected to the blower 18 to blow air on the seedlings to clean pests and water stains, improving the growth environment of the seedlings. At the same time, by moving the movable seat 25 to drive the nozzle 24 to slide inside the rear replacement seat 7 and fixing it with the second bolt, the width of the nozzle 24 after movement can be controlled for use with different seedbeds. When in use, the air source generated by the blower 18 enters the corresponding intake hose through the distribution box 22 and is sprayed out through the nozzle 24, thereby further improving the practicability of the equipment.

[0025] In this embodiment, the adjusting mechanism includes adjusting seats 12 relatively installed at the bottom of the transporter main body 1. Two adjusting blocks 13 are slidably installed on the outer walls of the two adjusting seats 12. A connecting plate 15 is commonly installed on one side of a corresponding set of adjusting seats 12. A bidirectional screw rod 14 is commonly threadedly installed inside the two connecting plates 15. Both ends of the bidirectional screw rod 14 are rotatably connected to fixing plates 16 and fixed on the transporter main body 1. One end of the bidirectional screw rod 14 penetrates through the corresponding fixing plate 16 and is connected to a driving motor 17. The tops of the plurality of universal wheels 2 are respectively fixed to the bottoms of the corresponding adjusting seats 12.

[0026] In this embodiment, a cavity 19 is opened inside the transporter main body 1. A storage battery 20 is provided inside the cavity 19. The storage battery 20 is used to provide power for the electrical equipment on the device. An inspection cover 21 for later maintenance and repair is rotatably connected to the upper part of the inner wall of the cavity 19. The inspection cover 21 facilitates the later maintenance of the storage battery 20. The inspection cover 21 is flush with the seedling placement area at the top of the transporter main body 1 in the closed state. A charging station for charging the storage battery 20 is installed on the outer wall of the transporter main body 1.

[0027] The working principle is as follows: In actual use of the present invention, first check whether the transporter main body 1 and its components are in good condition, and ensure that the battery 20 has sufficient power. If the power is insufficient, it can be charged through the charging station on the outer wall of the transporter main body 1. According to the width of the seedbed guide rail 3, start the drive motor 17 of the adjustment mechanism to drive the bidirectional screw 14 to rotate, so that the adjustment blocks 13 on the two sides of the adjustment seat 12 move relatively or in the opposite direction, and then adjust the spacing of the universal wheels 2 to make it fit the seedbed guide rail 3. Place the seedlings at the seedling placement position of the transporter main body 1. If the seedlings on the seedbed are arranged messily, start the electric push rod 11 of the lifting mechanism to contract and drive the connecting rod 9 to move upward. The connecting rod 9 pulls the brush 8 to rise through the swing arm 5; when the electric push rod 11 extends, the brush 8 descends to comb the seedlings to make them neatly arranged. Push the transporter main body 1, and use the universal wheels 2 to move on the guide rail 3 to realize the transportation of seedlings.

[0028] When it is necessary to clean pests or water stains on the surface of the seedlings, start the blower 18. The air source reaches the nozzle 24 through the distribution box 22 and the intake hose 23 and is sprayed out. At the same time, the electric push rod 11 acts to drive the swing arm 5 to swing up and down. Through the lifting plate 26, the rear connecting rod 9 pulls the swing arm 5, and then drives the nozzle 24 to move up and down to blow and clean the seedlings comprehensively. If the width of the seedbed changes, loosen the second bolt at the top of the rear replacement seat 7, move the moving seat 25 on the outer wall of the nozzle 24 to adjust the width of the nozzle 24, and then tighten the second bolt to fix it to ensure the cleaning effect. After the transportation is completed, turn off the equipment, clean the transporter, and check the wear condition of the components to prepare for the next use.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
