Description

Technical Field

[0001] This invention relates to a taro planting vehicle, belonging to the field of agricultural tools. Background Technology

[0002] Currently, taro cultivation generally follows traditional organic farming techniques, relying heavily on manual labor. Although the level of agricultural mechanization in my country has been continuously improving in recent years, machinery is mainly used for land preparation and ridging in taro cultivation. Steps such as digging, sowing, and covering with soil still rely on manual labor. Labor costs remain the highest expense in the taro industry. Furthermore, because taro cultivation in my country is primarily conducted by small-scale, individual farmers, it is difficult to achieve standardized and large-scale production, hindering economic efficiency and failing to meet the demands of modern, efficient, simplified, labor-saving, and standardized agricultural production. Large-scale cultivation often results in losses due to excessive labor. Without changing the existing traditional cultivation techniques, the taro industry will struggle to transform into a modern, high-efficiency agricultural industry.

[0003] In addition, while taro planting machinery already exists abroad, in China, due to the limited number of institutions engaged in taro research, the lack of scientific and technological personnel, insufficient industrial integration, and the lack of systematic and continuous technological innovation and services, related machinery products are largely absent from the Chinese market. Such machinery is characterized by high labor intensity, low efficiency, inconsistent planting techniques, and high subsequent cultivation and management costs, which is detrimental to increasing yield. Summary of the Invention

[0037] The frame 1 is provided with a limiting part 13, and the outer shell 31 is surrounded by a limiting groove 39 that is slidably connected to the limiting part 13 to limit the stroke of the shoveling mechanism 3.

[0038] The feeding mechanism 5 includes a motor 51 located at the bottom of the frame 1. The motor 51 is linked to a motor push rod 52. The other end of the motor push rod 52 is fixed to a U-shaped push frame 53 that is slidably installed at the bottom of the frame 1. Two fixed blocks 54 with sliding grooves are fixed on the U-shaped push frame 53. A feeding shovel 55 located below the discharge port 11 is slidably installed between the fixed blocks 54. A T-shaped frame 56 is fixed at the bottom of the frame 1. The T-shaped frame 56 is provided with a straight groove 57 and a downward-facing curved groove 58. The two ends of the feeding shovel 55 are slidably connected to the straight groove 57 and the curved groove 58 respectively through connecting rods. The feeding shovel 55 adjusts its angle through the motor 51 to feed the seeds falling from the discharge port 11 into the pit dug by the soil shoveling mechanism 3.

[0039] The seed metering mechanism 2 also includes a drive component, which includes drive wheels 23 located on both sides of the frame 1. A ratchet assembly 24 is rotatably connected to the drive wheels 23. The ratchet assembly 24 is connected to the seed metering disc 22 via a belt 25. The ratchet assembly 24 can prevent the planting vehicle from reversing and control the direction of use.

[0040] The frame 1 is provided with two tray frames 14, each of which is provided with a rotating wheel 15. The other end of the belt 25 is provided on the rotating wheel 15. A connecting shaft 16 is provided between the rotating wheels 15. The seed metering tray 22 is rotatably mounted on the tray frame 14 through the connecting shaft 16. The seed metering tray 22 is used to hold seeds.

[0041] The outer wall of the seed metering tray 22 has a number of seed metering grooves 221 evenly distributed around the periphery. The seed metering tray 22 is provided with a seed metering shell 222 fixed on the connecting shaft 16. The seed metering shell 222 is provided with an opening 223 that allows some of the seed metering grooves 221 to communicate with the external environment. The seed metering shell 222 can restrict the seeds in the seed metering tray 22 from scattering.

[0042] The limiting part 13 includes a bent bracket 131 and a pin 132. The pin 132 is detachably mounted on the bracket 131. A lever 133 is provided through the pin 132. The pin 132 is provided with a locking component, which includes a mounting cavity 134 disposed in the pin 132. A locking block 135 is provided in the mounting cavity 134. A movable sleeve 138 is fixed outside the lever 133. One end of the movable sleeve 138 is rotatably connected to a drive rod 136. The other end of the drive rod 136 is connected to the bottom of the locking block 135. Both ends of the locking block 135 are locked to the mounting cavity 134 through limiting blocks 137. Limiting grooves 1341 are provided on both sides of the mounting cavity 134. A control spring 139 is installed in the limiting groove 1341. The control spring 139 abuts against the bottom of the limiting block 137.

[0043] When in use, the drive wheel 23 rotates forward while the ratchet assembly 24 engages. The drive wheel 23 drives the belt 25 to rotate the seed metering disc 22, causing the taro in the feed hopper 21 to enter the seed metering disc 22 one by one, and causing the taro in the seed metering disc 22 to enter the seed metering pipe 26 one by one.

[0044] By pressing down the push plate 41, the gear 63 rotates forward, driving the rack 64 forward, which in turn pushes the U-shaped frame 61 and the seeding push rod 27 connected to the rack 64 to move. The push rod 32 pushes down the shovel 313 of the soil-shoveling mechanism 3 and shovels it into the soil. At the same time, the hydraulic component 311 pulls up the soil-shoveling push rod 312, causing the shovel 313 to retract. The push plate 41 is released, and the push plate 41 rebounds. The shovel 313 carries the soil out. When the taro enters the pit, the hydraulic component 311 pushes down the soil-shoveling push rod 312, and the shovel 313 is released. The soil in the shovel 313 falls into the pit and buries the taro.

[0045] As the push plate 41 is pressed down, the seeding push rod 27 is pushed forward, and the taro in the seeding pipe 26 enters the feeding mechanism 5. At this time, the motor 51 pushes the feeding shovel 55, which extends forward and rotates counterclockwise at a certain angle, causing the taro to fall from the feeding shovel 55 into the pit.

[0046] 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.
