Description

Seedling transplanting device for agricultural planting

Technical Field

The invention relates to the technical field of agricultural planting, in particular to a seedling transplanting device for agricultural planting.

Background Art

Agricultural planting refers to the process of using land resources for plant production, including a series of activities such as planting crops, managing plant growth, harvesting and processing crops. Seedlings refer to young plants in the early growth stage after seeds germinate, which will affect the yield of agricultural crops. Seedlings require a transplanting device when transplanting. This is a device used to transplant seedlings from nursery beds or other culture environments to planting sites. Such devices can improve transplanting efficiency, reduce damage to seedlings, and ensure that seedlings can quickly adapt to the new environment.

In the prior art, a Chinese patent with the authorization announcement number CN219182062U discloses a portable seedling transplanter, which belongs to the field of agricultural planting. The technical key points are that a dial plate is set, the rotating plate rotates through the active rod to drive the lifting ring to slide along the outer wall of the limit strip, the lifting ring slides and drives three sets of driven rods to move synchronously, and then the lifting ring slides and drives the connecting plate to rotate through the driven rod, the connecting plate rotates and drives the dial plate to rotate, the dial plate rotates and drives the soil in the transplanting area to dig a pit, and then the seedling falls into the pit from the bottom end of the sleeve, so as to realize the rapid transplanting operation of the seedling;

In the prior art, a Chinese patent with the authorization announcement number CN219741213U discloses a seedling transplanting device, the technical points of which are that the seedling transplanting device sets a placement seat for placing seedlings connected by multiple torsion springs under the plate body, so that when the seedlings are put into the seedling delivery tube, they do not need to be pushed to a long distance. The seedlings placed on the placement seat can be dropped into the seedling delivery tube by simply pushing the plate body, thus avoiding damage to the roots of the seedlings and the soil around the roots. The seedling transplanting device reduces the friction between the two by installing a pulley at the end of the plate body that has friction with the placement seat, so that the friction between the two is smaller when the two slide relative to each other, thereby reducing damage to parts;

In the prior art, a Chinese patent with authorization announcement number CN216253901U discloses a seedling transplanter, the technical key points of which are to set a guide member and a guide groove so that the digging member rotates while moving downward, thereby improving the digging effect; to set a scraping groove so that the excavated soil can cover the plant root system, saving the filling step; and to set an unfolding mechanism so that the soil and seedlings can be directly placed in the pit after digging, thereby improving the transplanting effect.

At present, most transplanting devices on the market still have certain shortcomings when in use. As described in the above-mentioned document, the seedlings fall from the bottom of the sleeve into the pit to achieve rapid transplanting of the seedlings.

When the transplanting device places the seedlings, the soil-moving piece 4 is inserted into the planting position in the soil, and then the seedlings are placed inside the support plate 108 through the feed port on the top of the device body 1. After the seedlings are placed, the gravity of the support plate 108 increases, thereby driving the connecting ring 107 to move. When the connecting ring 107 moves, it can drive the guide block 106 to move. When the guide block 106 moves, it can slide downward through the first guide groove 101. The sliding of the guide block 106 can also drive the winding belt 103 to move. When the winding belt 103 moves, it can change the movement through the first roller 102. The winding belt 103 can drive the first roller 102 to rotate at the same time. After the movement direction of the winding belt 103 is changed, the counterweight block 104 can be pulled to move. When the counterweight block 104 moves, it can slide upward through the sliding groove 105. The counterweight block 104 can generate an opposite force with the support plate 108, thereby reducing the speed of the support plate 108 when it falls.

When the support plate 108 rotates, it can rotate through the rotating shaft at the bottom of the connecting ring 107. When the support plate 108 rotates, it drives the second fixing plate 110 to rotate. When the second fixing plate 110 rotates, it can squeeze the first spring 111. After the support plate 108 is squeezed to the specified position, the seedlings on the upper surface can fall into the soil. At this time, the seedlings can be planted to prevent the seedlings from falling too quickly and being damaged, thereby improving the protection strength of the seedlings during transplanting.

Embodiment 2: As shown in FIG. 3 , FIG. 4 and FIG. 7 , the present invention provides the following technical solution: In order to solve the problem that when the seedlings of the transplanting device fall to the bottom of the device, the roots are easily damaged due to vibration, which reduces the survival rate, a buffer mechanism is disclosed:

The buffer mechanism includes a connecting pipe 113, one end of which is symmetrically connected to the bottom of the air cushion 112, and the other end of the connecting pipe 113 is connected to an extrusion bag 114, which is connected to the inside of the placement groove 115. The extrusion bag 114 is connected to the air cushion 112 through the connecting pipe 113. The placement groove 115 is opened on the side of the first guide groove 101, and the bottom surface of the first guide groove 101 close to the air cushion 112 is symmetrically connected to the second spring 116. The upper surface of the inner part of the sliding groove 105 is connected to a friction cylinder plate 117, and the upper surface of the inner part of the sliding groove 105 is symmetrically connected to the third spring 118. The second spring 116 and the third spring 118 are respectively connected to the guide groove 101 and the guide groove 101. The guide block 106 and the counterweight block 104 form a telescopic structure. When the seedling falls through the sliding mechanism, the guide block 106 can slide through the first guide groove 101. When the guide block 106 slides down to the top of the air cushion 112, it can be squeezed. When the air cushion 112 is squeezed, it can be deformed by its own material. When the air cushion 112 is deformed, the internal gas can be transported to the inside of the squeezing bag 114 through the connecting pipe 113. Since the pipeline transportation efficiency of the connecting pipe 113 is not very high, the air cushion 112 will generate resistance to reduce the impact force of the guide block 106 falling, and the squeezing bag 114 will expand inside the placement groove 115 after receiving the gas. When the squeezing bag 114 expands The side of the guide block 106 can be squeezed. When the guide block 106 is squeezed, the impact force of the fall can be reduced. As the air cushion 112 is squeezed, the resistance generated by the squeezing bag 114 will gradually increase. When the guide block 106 slides down to the top of the second spring 116, it can be squeezed. When the second spring 116 is squeezed, it can generate an upward reaction force through its own elastic force. The reaction force will further reduce the impact force of the guide block 106 falling, and the squeezing of the squeezing bag 114 can reduce the elastic vibration generated by the elastic force of the second spring 116. At the same time, when the guide block 106 slides downward, the counterweight block 104 will slide upward under the action of the winding belt 103, and the counterweight block When 104 slides up to the side of the friction sleeve 117 through the sliding groove 105, it can be squeezed. The material of the friction sleeve 117 can generate resistance, thereby attenuating the impact force of the counterweight block 104 sliding up. When the counterweight block 104 slides up to the bottom of the third spring 118, it can be squeezed. The reaction force generated by the squeezing of the third spring 118 can once again attenuate the impact force of the counterweight block 104. The resistance encountered by the counterweight block 104 and the guide block 106 can reduce the force impact of the support plate 108, thereby reducing the impact on the seedlings on the upper surface of the support plate 108, preventing the roots of the seedlings from being damaged, further improving the protection of the seedlings, and improving the survival rate of the seedlings.

Embodiment 3: As shown in FIG. 2 , FIG. 8 , FIG. 9 and FIG. 10 , the present invention provides the following technical solutions: In order to solve the problem that the transplanting device is difficult to maintain the same protection effect on seedlings of different weight types and there are great restrictions on the type and weight of the seedlings, a clamping mechanism is disclosed:

The second clamp block 125 is rotatably connected to the inner side. The first clamp block 124 and the second clamp block 125 are respectively attached to the surface of the winding belt 103. A connecting belt 126 is connected between the top of the first clamp block 124 and the second clamp block 125. The upper surface of the connecting belt 126 is connected to the bottom end of the first pull rope 127. The top end of the first pull rope 127 is connected to the bottom of the threaded block 122. The connecting belt 126, the first clamp block 124 and the second clamp block 125 are transmission connected. Before the transplanting device is used, rotating the rotating ring 119 can drive the T-shaped ring 120 to rotate. When the T-shaped ring 120 rotates The rotating ring 119 can rotate through the T-slot 121, and the threaded block 122 can be driven to slide through the thread when the rotating ring 119 rotates. The threaded block 122 can slide through the second guide groove 123 when the threaded block 122 slides. When the threaded block 122 slides, the first pull rope 127 can be pulled to move. When the first pull rope 127 moves, the connecting belt 126 can be driven to move. When the connecting belt 126 moves, the first clamping block 124 and the second clamping block 125 can be driven to rotate at the same time. The first clamping block 124 can rotate through the first guide groove 101, and the second clamping block 125 can rotate through the first clamping block 12 4 rotates, the first clamping block 124 and the second clamping block 125 can clamp the winding belt 103 when they rotate, and the winding belt 103 can squeeze the first roller 102 after being clamped, and the friction force can be changed when the winding belt 103 and the first roller 102 are squeezed, and the sliding speed of the guide block 106 can be adjusted when the friction force changes, and the sliding speed of the seedling can be changed when the guide block 106 changes, so that the transplanting device can adjust the sliding speed according to the weight of different types of seedlings, which reduces the restriction of the device on the seedling type and once again improves the protection effect of the device on the seedlings.
