Description

Technical Field

[0001] This utility model relates to the technical field of vegetable seedling transplanting equipment, specifically an automated vegetable transplanting machine. Background Technology

[0002] Vegetable transplanting is a crucial step in agricultural production. Traditional manual transplanting methods suffer from high labor intensity, low efficiency, and uneven plant spacing. While semi-automatic transplanting equipment has been gradually adopted with the development of agricultural mechanization, it still has significant drawbacks:

[0003] 1. Insufficient automation: Existing equipment relies heavily on manual labor for key processes, such as manually picking up seedlings, feeding seedlings, and changing seedling trays. Operators need to bend over or stand for long periods of time, which can easily lead to fatigue, and manual intervention has become a bottleneck restricting efficiency improvement.

[0004] 2. High labor costs: During the peak transplanting season, a large number of laborers are required to work together, which not only increases production costs, but also affects production plans due to the shortage of agricultural labor.

[0005] 3. Poor adaptability to small-scale production: Most large-scale transplanting equipment on the market is designed for intensive farms. It has a complex structure and high purchase cost, making it difficult to adapt to the current situation of scattered plots and limited planting scale of small and medium-sized planting bases, resulting in a low rate of mechanization.

[0006] 4. Inefficient workflow: The existing machinery often requires independent operation or manual coordination for seedling delivery, picking, and planting, which can easily lead to problems such as missing seedlings, damaged seedlings, or inconsistent planting depth, affecting the survival rate and standardized production.

[0007] Therefore, there is an urgent need for equipment that can completely automate the entire transplanting process, significantly reduce reliance on manpower, and also meet the needs of small and medium-sized production, in order to solve the above-mentioned industry pain points. Utility Model Content

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] Please see Figure 1-13An automated vegetable transplanter includes a main frame structure 1, a tray feeding device 20, a seedling clamping device 30, a seedling transplanting device 10, a seeding device 40, and a soil-crushing device 50. A foot pedal 2 is connected to the rear end of the main frame structure 1, serving as the operator's work area. Two sets of seats 3 are fixedly connected to one side of the foot pedal 2 to facilitate seated operation and reduce worker fatigue. A suspension 4 is installed at the front end of the main frame structure 1, connected to a tractor via a three-point suspension 4. The tractor can raise or lower the equipment. During operation, the equipment is lowered via the three-point suspension 4 for transplanting; when not in operation, the equipment is raised, suspending itself for easy towing. Two sets of seedling transplanting devices 10 are fixedly connected to the upper end of the main frame structure 1. A tray feeding device 20 is fixedly connected to the middle of each seedling transplanting device 10, and a seedling clamping device 30 is installed on one side of each tray feeding device 20. A soil-crushing device 50 and a seeding device 40 are respectively installed at the lower end of the main frame structure 1. The soil-crushing device 50 is located near the seeding device 40. The specific operating procedure for the front part of the seedling device 40 is as follows: the operator sits on the seat 3 and places the seedling trays from the seedling tray rack 7 into the tray delivery device 20. The tray delivery device 20 conveys the seedling trays via the support rods 214 between the chain belts. After the seedling trays are conveyed to the front position, the seedling clamping device 30 at the front end clamps the seedlings. The empty seedling trays return along the guide plate 213 and are removed by the operator. After clamping the seedlings, the seedling clamping device 30 moves backward and releases the seedlings, causing them to fall into the transplanting cups 105 in the transplanting device 10. As the seedling cup 105 moves along the chain of the square drive, it automatically opens the bottom of the seedling cup when it reaches the feed inlet 106. The seedling falls down from the seedling cup and passes through the feed inlet 106, falling directly into the seedling sowing device 40, that is, into the planting cup 406. The planting cup 406 is powered by the walking wheel 412. At the same time as the lower part of the planting cup 406 is inserted into the soil, the lower duckbill opens, thereby loading the seedling in the planting cup 406 into the soil, and then the soil is covered by the rear side covering wheel 403.

[0048] In the above technical solution, a sunshade 6 is connected to the top of the main frame structure 1 via a first support rod 5 to prevent the seedlings and operators from being sunburned during operation. Multiple layers of evenly spaced seedling tray racks 7 are fixedly connected to the first support rod 5 below the sunshade 6 to place the seedlings to be transplanted and to facilitate the operation of the operators.

[0049] In the above technical solution, the transplanting device 10 includes a second support rod 101, a mounting plate 102, a wheel support column 103, a transmission gear 104, and a transplanting cup 105. Several second support rods 101 are fixedly connected to the lower end of the mounting plate 102. The lower ends of the second support rods 101 are all fixedly connected to the main frame structure 1. Four sets of wheel supports 103 arranged at the vertices of a rectangle are fixedly connected to the mounting plate 102. The upper ends of the wheel supports 103 are rotatably connected to the transmission gears 104. The transmission gears 104 are interconnected by a chain, and the transplanting cup 105 is fixedly connected to the chain. A guide port 106 is opened on the mounting plate 102. An opening and closing structure 107 is fixedly connected to the mounting plate 102 on both sides of the guide port 106. The opening and closing structure 107 is used to automatically open the bottom of the transplanting cup 105. A transmission component is fixedly connected to one side of one set of transmission gears 104. The transmission component is connected to the seedling clamping device 30 and the seedling sowing device 40 respectively.

[0050] In this utility model, the transplanting cup 105 mainly includes a seedling cup body 112. The lower end of the seedling cup body 112 is provided with a feeding port. A closing cover 108 is rotatably connected to one side of the feeding port. The closing cover 108 can be closed and connected inside the feeding port to realize the transplanting of seedlings. A cover-opening wheel 109 is rotatably connected to one side of the closing cover 108. The opening and closing structure 107 includes a support frame 110 and a guide plate 111. When the seedling cup body 112 moves to the position of the support frame 110, one side of the guide plate 111 contacts the upper middle part of the cover-opening wheel 109. Then, as it continues to move, the cover-opening wheel 109 rolls downward and connects to the bottom of the guide plate 111. At the same time, the cover-opening wheel 109 drives the closing cover 108 to flip, thereby opening the feeding port and allowing the seedlings inside to fall downward. Then, they fall directly onto the seedling sowing device 40 through the feeding port 106.

[0051] In the above technical solution, the tray feeding device 20 includes a tray feeding frame 201, a first chain guide wheel 202, a second chain guide wheel 203, a ratchet gear 204, a ratchet pawl 205, a rotating rod 206, a telescopic cylinder 207, a stop rod 208, a stop block 209, a first spring 210, and a fixing rod 211. A guide slot 212 is provided in the middle of the upper end of the mounting plate 102. A guide plate 213 is fixedly connected to the mounting plate 102 on one side of the lower end of the guide slot 212. The tray feeding frame 201 is fixedly connected to the upper end of the guide slot 212. Two sets of first chain guide wheels 202 are rotatably connected inside the tray feeding frame 201. The first chain guide wheels 202 are respectively connected to the second chain guide wheels 203 via chain belt transmission. 3. Also rotatably connected within the tray feeding frame 201, several support rods 214 are fixedly connected between the two sets of drive chains. The shaft of the first chain guide wheel 202 passes through the tray feeding frame 201 and is fixedly connected to the ratchet gear 204. A rotating rod 206 is rotatably connected to the shaft on one side of the ratchet gear 204. One end of the rotating rod 206 is connected to a telescopic cylinder 207, which is rotatably connected to the outer wall of the tray feeding frame 201. The other end of the rotating rod 206 is rotatably connected to a ratchet pawl 205. A torsion spring is fixedly installed between the ratchet pawl 205 and the rotating rod 206. One end of the ratchet pawl 205 is meshed with the ratchet gear 204. A stop rod 20 is rotatably connected to the tray feeding frame 201 on one side of the ratchet gear 204. 8. The end of the anti-reverse rod 208 contacts the rotating rod 206. An anti-reverse block 209 is fixedly connected to the anti-reverse rod 208. One end of the anti-reverse block 209 meshes with the ratchet 204. A first spring 210 is fixedly connected to one side of the end of the anti-reverse rod 208. The other end of the first spring 210 is fixedly connected to the fixed rod 211. The fixed rod 211 is fixedly connected to one side of the tray feeding frame 201. In use, the gear air pump 502 provides air to the telescopic cylinder 207. The telescopic cylinder 207 drives the rotating rod 206 to rotate. The rotating rod 206 drives the ratchet pawl 205 to reciprocate. Thus, the ratchet pawl 205 continuously drives the ratchet 204 to rotate. During this process, the ratchet pawl 205 pushes the ratchet 204. When 204 rotates, the anti-reverse lever 208 and the anti-reverse block 209 move toward the ratchet 204 under the pull of the first spring 210 and gradually engage. During the reverse movement of the ratchet pawl 205, the ratchet pawl 205 passes over the adjacent ratchet teeth. At the same time, the rotating lever 206 pushes the anti-reverse lever 208 to move outward so that the anti-reverse block 209 moves away from the ratchet teeth. When the ratchet pawl 205 passes over the ratchet teeth and re-engages with the ratchet teeth, the anti-reverse block 209 just disengages from the ratchet teeth, thereby driving the ratchet 204 to rotate continuously. The ratchet 204 drives the first chain guide wheel 202 to rotate. The first chain guide wheel 202 drives the second chain guide wheel 203 to rotate through the chain belt, and then drives the seedling tray to rotate through the support rod 214 between the chain belts.

[0052] In the above technical solution, the seedling clamping device 30 includes a third support rod 301, a fixing plate 302, a mounting frame 303, a sliding guide rail 304, a sliding guide block 305, a connector 306, a seedling clamp assembly 307, a swing arm 308, and a rotating rod 309. Several third support rods 301 are fixedly connected to one side of the mounting plate 102. The upper end of the third support rods 301 is fixedly connected to the fixing plate 302.

Sliding grooves 310 are respectively opened on the fixing plate 302 at the upper end of the connector 306. The top of the connector 306 is slidably connected to the slide groove 310. The upper middle part of the mounting frame 303 is rotatably connected to the rocker arm 308. The other end of the rocker arm 308 is rotatably connected to the rotating rod 309. The rotating rod 309 is rotatably connected to the lower end of the fixed plate 302. The rotating shaft of the rotating rod 309 passes through the upper end of the fixed plate 302 and is connected to the transmission component. In use, the transmission component drives the rotating rod 309 to rotate in a circle. The other end of the rotating rod 309 drives the mounting frame 303 to reciprocate and translate at the lower end of the fixed plate 302 through the rocker arm 308. During this process, the mounting frame 303 drives the seedling clip assembly 307 to move back and forth. That is, when the seedling clip assembly 307 is at the front end, it can clamp the seedling at the front end of the tray delivery device 20. When the seedling clip assembly 307 moves to the rear end, it automatically releases the seedling, allowing the seedling to fall into the transplanting device 10.
