Description

Technical Field

[0001] The present invention relates to the technical field of off-season transplanting of seedlings, and in particular to an automated off-season transplanting device and method for large-scale seedlings. Background Art

[0002] With the rapid development of urban construction and the continuous improvement of people's living standards, people's demands for improving the ecological environment have become increasingly strong. Therefore, large-scale off-season transplanting will occur. The meaning of off-season transplanting is to plant seedlings in seasons that are not suitable for greening. Transplanting equipment is required for off-season transplanting.

[0003] During the use of existing large-scale off-season transplanting equipment for seedlings, in order to provide the moisture required for off-season transplanting in the initial stage, a watering mechanism is generally added to the transplanting equipment. However, when the watering mechanism carried by the existing transplanting equipment is used, there are two irrigation methods. One is to water the pre-buried holes, which easily causes water to accumulate at the root position of the seedlings, resulting in root rot of the transplanted seedlings. The other is to water the transplanted seedlings as a whole. However, during off-season transplanting, the buried soil is relatively dry, which will cause the upper soil to absorb the irrigation water, and the water cannot penetrate to the bottom, causing water shortage at the roots of the seedlings, thereby causing the existing transplanting equipment to lack use value. Summary of the invention

[0004] The present invention discloses an automated off-season transplanting device for large-scale seedlings, aiming to solve the problem that during the use of the existing off-season transplanting device for large-scale seedlings, in order to provide the moisture required for off-season transplanting in the initial stage, a watering mechanism is generally added to the transplanting device. However, when the watering mechanism carried by the existing transplanting device is in use, there are two irrigation methods. One is to water the pre-buried holes, which easily causes water to accumulate at the root position of the seedlings, resulting in root rot of the transplanted seedlings.

[0006] By setting up a multi-level water-guiding mechanism, after the large-sized seedlings are introduced into the pre-buried pit, the lifting frame is lifted, and the cylinder four is adjusted to drive the irrigation pipe to go deep into the bottom of the pre-buried pit. Then the pre-buried pit is filled with soil through the filling mechanism. When the soil covers the roots of the seedlings, the water pump is started, and the water pump transports water to the irrigation pipe, and sprays it to the soil close to the seedlings through the guide nozzle. The cylinder four is adjusted simultaneously to drive the irrigation pipe to gradually rise, thereby realizing soil irrigation from bottom to top around the roots of the seedlings, completing multi-level irrigation, avoiding root rot of the seedlings, and avoiding serious water loss, ensuring that the seedlings after off-season transplantation will not die due to lack of water in the early stage, thereby improving the use value of the off-season transplanting equipment.

[0010] In a preferred solution, a dual positioning mechanism is equidistantly provided inside the lifting frame, and the dual positioning mechanism is spaced apart from the multi-level water guiding mechanism, the dual positioning mechanism comprises a built-in mounting plate, the built-in mounting plate is fixedly connected to the inner wall of the lifting frame, and extrusion spring rods are fixedly connected to the side of the built-in mounting plate facing the center point of the lifting frame at equal distances, one end of the multiple extrusion spring rods is fixedly connected to the same positioning clamping plate, and a guide arc plate is fixedly connected to the top of the positioning clamping plate.

[0011] By providing a double positioning mechanism, when positioning the seedlings, due to the large size of the seedlings and their own gravity, in order to improve the firmness of their positioning and clamping, they need to be doubly positioned and pressed between multiple positioning clamps through various guide arc plates. The positioning clamps squeeze the roots of the seedlings under the action of the extrusion spring rods at the rear to complete the initial clamping. After the initial clamping, if the extrusion received by the pressure sensor does not reach the specified value, the hydraulic cylinder 2 is adjusted to drive the rear support frame to squeeze the positioning clamp, so that the interaction force between the positioning clamp and the roots of the seedlings gradually increases. When the pressure sensor gradually approaches the specified value, the hydraulic cylinder 2 stops adjusting to complete the secondary positioning and clamping of the roots of the seedlings. At the same time, the extrusion force on the roots of the seedlings is controlled within the specified value to avoid excessive damage due to extrusion.

[0015] By setting up a filling mechanism, after the lifting frame is moved out of the pre-buried pit, the second adjusting cylinder drives the filling frame on the pushing plate to push the soil around the pre-buried pit. As the two filling frames approach, most of the soil is filled into the pre-buried pit. At this time, each pressing block is staggered with the irrigation pipe. By starting the forward and reverse motor and continuously adjusting the third cylinder, the pressing block rotates and presses within a certain range to improve the density of soil filling.

[0016] In a preferred solution, the arc surface of the filling frame is fixedly connected with fitting blocks at equal distances, and the top of each fitting block is fixedly connected with a top frame, the side of the top frame facing downward is fixedly connected with cylinder three, the output end of cylinder three is fixedly connected with a lower pressure plate, the bottom of the lower pressure plate is fixedly connected with an arc-shaped limit rail, the internal sliding connection of the arc-shaped limit rail is connected to a limit slider, the bottom of the limit slider is fixedly connected with a pressing block, the top of the lower pressure plate is fixedly connected with a forward and reverse motor, the output shaft of the forward and reverse motor is fixedly connected with a driving connecting rod through a coupling, and one end of the driving connecting rod is fixedly connected to one side of the limit slider.

[0017] An automated large-scale seedling off-season transplanting method, using the automated large-scale seedling off-season transplanting device as described above, comprises the following steps: Step 1: The moving mechanism moves the seedlings to the top of the pre-buried pit, and the adjustment cylinder 1 drives the lifting frame to move to the bottom of the pre-buried pit. Then the hydraulic cylinder 3 drives the adapter pressing frame to reset, and the positioning airbag gradually returns to its original state. Then the adjustment cylinder 2 drives the rear support frame to separate from the positioning splint, and the cylinder 1 drives the lifting frame to reset, and the seedlings are retained in the pre-buried pit. The adjustment cylinder 4 drives the irrigation pipe to go deep into the bottom of the pre-buried pit. Step 2: After the irrigation pipe position is adjusted, the second adjusting cylinder drives the soil filling frame on the push plate to push the soil around the pre-buried pit. As the two soil filling frames approach, most of the soil is filled into the pre-buried pit. At this time, each pressing block is staggered with the irrigation pipe. The forward and reverse motor and the uninterrupted adjustment cylinder 3 are started, and the pressing block rotates and presses within a certain range. Step 3: After the filling operation is completed, start the water pump, which will transport water to the irrigation pipe and spray it to the soil near the seedlings through the guide nozzle. Synchronously adjust cylinder four to drive the irrigation pipe to gradually rise, so as to realize soil irrigation from bottom to top around the roots of the seedlings and complete multi-level irrigation. When the irrigation pipe is gradually lifted from the soil, the diverter valve opens, and part of the water is transported to the water delivery plate and sprayed to the branches and leaves of the seedlings through various atomizing nozzles to spray water for the newly transplanted seedlings. When the irrigation pipe is removed from the soil, the water pump is turned off, and cylinder one is adjusted again to drive the lifting frame to move above the seedlings, and the moving mechanism is moved away from the transplanting position of the seedlings, ending the large-scale seedling transplanting operation.

When the soil covers the roots of the seedlings, the water pump is started, and the water pump transports water to the irrigation pipe, and sprays it to the soil close to the seedlings through the guide nozzle. The cylinder four is adjusted synchronously to drive the irrigation pipe to gradually rise, thereby realizing soil irrigation from bottom to top around the roots of the seedlings, completing multi-level irrigation, avoiding root rot of the seedlings, and avoiding serious water loss, ensuring that the seedlings after off-season transplantation will not die due to lack of water in the early stage.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] The automated off-season transplanting equipment for large-scale seedlings disclosed in the present invention is mainly applied to the off-season transplanting equipment for large-scale seedlings. During use, in order to provide the moisture required for off-season transplanting in the initial stage, a watering mechanism is generally added to the transplanting equipment. However, when the watering mechanism carried on the existing transplanting equipment is in use, there are two irrigation methods. One is to water the pre-buried holes. This method easily causes water to accumulate at the root position of the seedlings, resulting in root rot of the transplanted seedlings. The other is to water the transplanted seedlings as a whole. However, during off-season transplanting, the buried soil is relatively dry, which will cause the upper soil to absorb the irrigated water, and the water cannot penetrate to the bottom, resulting in a scene where the roots of the seedlings are short of water.

[0032] Reference Figure 1-Figure 10 , an automated large-scale seedling off-season transplanting device, comprising a moving mechanism 1 and a lifting frame 10, a multi-level water guide mechanism 9 is equidistantly arranged on the inner side of the lifting frame 10, and the multi-level water guide mechanism 9 comprises an irrigation pipe 901 and a limiting sleeve 902, the irrigation pipe 901 passes through the limiting sleeve 902, the limiting sleeve 902 is fixedly connected to the inner side wall of the lifting frame 10, and the lifting frame 10 is fixedly connected to a connecting frame 16 near the top of each limiting sleeve 902, the top of the connecting frame 16 is fixedly connected to a cylinder four 14, the output end of the cylinder four 14 is fixedly connected to an external plate 15, the external plate 15 is fixedly connected to the outer side wall of the irrigation pipe 901 near the top, the bottom of the irrigation pipe 901 is fixedly connected to a transfer sleeve frame 907, and the transfer The bottom of the sleeve frame 907 is fixedly connected to a guide pipe 909, and the inner wall of the guide pipe 909 is fixedly connected to a guide nozzle 908, which points to the center point of the lifting frame 10. The outer wall of the irrigation pipe 901 located above the transfer sleeve frame 907 is fixedly connected to an external ring rod 912, and the bottom of the external ring rod 912 is fixedly connected to two hydraulic cylinders 913, and the output ends of the two hydraulic cylinders 913 are fixedly connected to the same extrusion ring frame 914, which is located inside the transfer sleeve frame 907. The bottom of the extrusion ring frame 914 is fixedly connected to a sealing sleeve 915, and the sealing sleeve 915 is fixedly connected to the inner wall of the transfer sleeve frame 907. The irrigation pipe 901, the transfer sleeve frame 907 and the guide pipe 909 are connected.

[0033] In a specific application scenario, after the large-sized seedlings are introduced into the pre-buried pit, the lifting frame 10 is lifted, and the cylinder four 14 is adjusted to drive the irrigation pipe 901 to go deep into the bottom of the pre-buried pit, and then the pre-buried pit is filled with soil through the filling mechanism 12. When the soil covers the roots of the seedlings, the water pump 3 is started, and the water pump 3 transports water to the irrigation pipe 901, and sprays it to the soil close to the seedlings through the guide nozzle 908. The cylinder four 14 is adjusted synchronously to drive the irrigation pipe 901 to rise gradually, thereby realizing soil irrigation from bottom to top around the roots of the seedlings, completing multi-level irrigation, avoiding root rot of the seedlings, and avoiding serious water loss, ensuring that the seedlings after off-season transplantation will not die due to lack of water in the early stage, thereby improving the use value of the off-season transplanting equipment.

[0034] Specifically, during the lifting process of the irrigation pipe 901, the cutting blade 910 cuts the surrounding soil to reduce the resistance of the irrigation pipe 901 to lift. When the irrigation pipe 901 is taken out of the soil, there will be many remaining pits around the seedlings. If it rains, rainwater will more easily flow to the roots of the seedlings and be absorbed. At the same time, after the water flows from the irrigation pipe 901 to the inside of the transfer frame 907, the hydraulic cylinder 913 is continuously adjusted to drive the extrusion ring frame 914 to squeeze the water inside the transfer frame 907, so that it carries a greater impact when rushing out through the guide nozzle 908, and the water flows closer to the roots of the seedlings, reducing the dispersion loss of the water.

[0035] It should be noted that when the irrigation pipe 901 is gradually lifted from the soil, the diverter valve 905 is opened, and part of the water is transported to the water supply plate 904, and sprayed onto the branches and leaves of the seedlings through each atomizing nozzle 903, so as to spray water on the newly transplanted seedlings for maintenance, thereby further improving the survival rate of the transplanted seedlings.

[0039] Reference Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8In a preferred embodiment, a dual positioning mechanism 11 is equidistantly provided inside the lifting frame 10, and the dual positioning mechanism 11 is spaced apart from the multi-level water guiding mechanism 9, and the dual positioning mechanism 11 includes a built-in mounting plate 1101, and the built-in mounting plate 1101 is fixedly connected to the inner side wall of the lifting frame 10, and an extrusion spring rod 1106 is fixedly connected to the side of the built-in mounting plate 1101 facing the center point of the lifting frame 10 at an equal distance, and one end of the plurality of extrusion spring rods 1106 is fixedly connected to the same positioning clamping plate 1102, and a guide arc plate 1103 is fixedly connected to the top of the positioning clamping plate 1102, and a pressure measuring hole is opened at the center position of the positioning clamping plate 1102, and a pressure sensor 1113 is fixedly connected to the inside of the pressure measuring hole, and a telescopic connecting rod 1114 is fixedly connected to the inner side wall of the pressure measuring hole around the pressure sensor 1113 at an equal distance, and the ends of the plurality of telescopic connecting rods 1114 are fixedly connected to the inner side wall of the pressure measuring hole. It is fixedly connected to the same pressure plate 1104, which is in contact with the pressure sensor 1113. The built-in mounting plate 1101 is located on one side of both ends of the extrusion spring rod 1106 and is fixedly connected to hydraulic cylinder two 1109. The output ends of the two hydraulic cylinder twos 1109 are fixedly connected to the rear support frame 1108. The bottom of the positioning splint 1102 is fixedly connected to a suspension rod 1115, and the bottom of the suspension rod 1115 is fixedly connected to a mounting frame 1105. The mounting frame 1105 is fixedly connected to a positioning airbag 1110. The positioning splint 1102 is located above the positioning airbag 1110 and is fixedly connected to hydraulic cylinder three 1116.

[0040] Specifically, when positioning the seedlings, since the seedlings are large in size and have a large weight, in order to improve the firmness of their positioning and clamping, they need to be doubly positioned and pressed between multiple positioning clamps 1102 through each guide arc plate 1103. The positioning clamp 1102 squeezes the root of the seedling under the action of the rear extrusion spring rod 1106 to complete the initial clamping. After the initial clamping, if the extrusion received by the pressure sensor 1113 does not reach the specified value, the hydraulic cylinder 1109 is adjusted to drive the rear support frame 1108 to squeeze the positioning clamp 1102, so that the interaction force between the positioning clamp 1102 and the root of the seedling gradually increases. When the pressure sensor 1113 gradually approaches the specified value, the hydraulic cylinder 1109 stops adjusting to complete the secondary positioning and clamping of the root of the seedling. At the same time, the extrusion force on the root of the seedling is controlled within the specified value to avoid excessive damage due to extrusion.

[0041] It should be noted that before placing the seedlings into each positioning clamp 1102, the hydraulic cylinder three 1116 is adjusted to drive the adapter pressing frame 1107 to squeeze the positioning airbag 1110 below, so that the gas inside the positioning airbag 1110 flows downward. Since the three sides of the positioning airbag 1110 are blocked, the positioning airbag 1110 is transformed from the initial vertical shape to an L-like structure during the gas flow.
