[0026] According to this specific embodiment, the vehicle body 1 can travel in the planting field to drive the harvesting component to move.

[0027] Furthermore, the trenching mechanism 2 is arranged on one side of the vehicle body 1; the pressing mechanism 3 is arranged on one side of the vehicle body 1; the first mounting frame 4 is arranged at the bottom of the pressing mechanism 3; the loosening rake 5 is rotatably arranged on the inner side of the first mounting frame 4; the driving mechanism 6 is arranged on the inner side of the first mounting frame 4; the pressing mechanism 3 is used to drive the loosening rake 5 to rise and fall; the driving mechanism 6 is used to drive the loosening rake 5 to rotate.

[0028] In this embodiment, the trenching mechanism 2 is used to dig a trench in the planting field, the pressing mechanism 3 is used to drive the loosening harrow 5 to rise and fall, and the driving mechanism 6 is used to drive the loosening harrow 5 to rotate within a smaller angle range. The yams in the planting field are planted in rows. When used, the vehicle body 1 is started, and the trenching mechanism 2 is moved to the side of a row of yams to be harvested, which is consistent with the arrangement direction of the yams. Then the vehicle body 1 moves forward slowly, and the trenching mechanism 2 slowly digs a trench on the side of this row of yams. In the process of slowly digging the trench, the pressing mechanism 3 drives the first The mounting frame 4 moves downward, driving the loosening rake 5 to be inserted into the side of the row of yams away from the groove, and then the driving mechanism 6 drives the loosening rake 5 to rotate slightly in the direction of the groove, pushing the row of yams mixed with the soil in the direction of the groove to loosen the soil, and then the harvesters can directly take the yams out of the groove; adopting the above method, every time the vehicle body 1 moves forward a certain distance, the trenching mechanism 2 digs a groove, and at the same time, the loosening rake 5 at the rear loosens a part of the yams mixed with the soil, making it convenient for the harvesters to harvest the yams, thereby solving the problem of low harvesting efficiency of the existing yam harvesters. It should be noted that each time the vehicle body 1 drives the trenching mechanism 2 forward a certain distance, it must stop and wait for the loosening harrow 5 to be inserted into the planting field to loosen a part of the soil and yam and then move up to take them out. Only then can the vehicle body 1 continue to drive the trenching mechanism 2 forward. This is an intermittent operation. After the entire row of yams mixed with the soil is loosened toward the direction of the trench, the harvesters will take this row of yams out of the trench.

[0029] Furthermore, the angle adjustment member 21 is arranged on one side of the vehicle body 1; the sprocket frame 22 is arranged on one side of the angle adjustment member 21; the driving sprocket 23 is rotatably arranged on the sprocket frame 22; the driven sprocket 24 is rotatably arranged on the sprocket frame 22; the chain 25 is arranged on the driving sprocket 23 and the driven sprocket 24; a plurality of shovel blades 26 are respectively fixedly arranged on the chain 25; the motor 27 is fixedly arranged on one side of the sprocket frame 22; and the output end of the motor 27 is fixedly connected to the driving sprocket 23.

During the movement of the chain 25, the plurality of shovel blades 26 are driven to start moving. When digging a trench, the angle adjustment member 21 moves one end of the sprocket frame 22 downward, causing the sprocket frame 22 to tilt downward, and the plurality of shovel blades 26 start to dig the soil. The more the sprocket frame 22 tilts downward, the deeper the trench is dug.

[0031] Furthermore, the second mounting frame 211 is rotatably connected to the vehicle body 1 and fixedly connected to the sprocket frame 22, and is located on one side of the vehicle body 1; the cylinder end of the first hydraulic cylinder 212 is rotatably connected to the vehicle body 1, the output end of the first hydraulic cylinder 212 is rotatably connected to the second mounting frame 211, and the first hydraulic cylinder 212 is located on one side of the vehicle body 1.

[0034] In this embodiment, only one side of the sprocket frame 22 is fixedly connected to the second mounting frame 211, and the other side needs to be installed with the motor 27, so it is not stable enough. Therefore, the reinforcing plate 213 is provided to connect the side of the sprocket frame 22 on which the motor 27 is installed with the second mounting frame 211 to enhance stability.

[0035] Furthermore, the mounting plate 31 is arranged on one side of the vehicle body 1; the second hydraulic cylinder 32 is fixedly arranged on the mounting plate 31, and the output end of the second hydraulic cylinder 32 is fixedly connected to the first mounting frame 4; the two guide rods 33 are respectively fixedly connected to the first mounting frame 4, respectively slidably connected to the mounting plate 31, and respectively pass through the mounting plate 31.

[0036] In this embodiment, the mounting plate 31 is used to fixedly mount the second hydraulic cylinder 32 and slideably mount the two guide rods 33, the two guide rods 33 are used to guide the first mounting frame 4, and the second hydraulic cylinder 32 drives the first mounting frame 4 to rise and fall, thereby driving the loosening rake 5 to rise and fall.

Driven by the second hydraulic cylinder 32, the multiple rake nails 52 are inserted into the soil from the side of a row of yams away from the groove, and then the driving mechanism 6 drives the rotating block 51 to rotate, and the rotating block 51 drives the multiple rake nails 52 to rotate in the direction of the groove, pushing the yams mixed with the soil in the direction of the groove to loosen the soil.

[0039] Furthermore, the connecting member 61 is fixedly arranged on the top of the rotating block 51; the cylinder end of the third hydraulic cylinder 62 is rotatably connected to the first mounting frame 4, the output end of the third hydraulic cylinder 62 is rotatably connected to the connecting member 61, and the third hydraulic cylinder 62 is located on the inner side of the first mounting frame 4.

[0040] In this embodiment, the connecting member 61 is fixedly arranged on the top of the rotating block 51, and is used to be rotatably connected to the output end of the third hydraulic cylinder 62. When the third hydraulic cylinder 62 is extended, the rotating block 51 is driven to rotate through the connecting member 61, and the rotating block 51 drives the multiple rake nails 52 to rotate in the direction of the groove.

[0042] In this embodiment, the two guide rails 311 are used to slide and install the plate body 312, and the fourth hydraulic cylinder 313 is used to drive the plate body 312 to slide. The sliding of the plate body 312 can adjust the positions of the multiple rake nails 52 below. When the yam to be dug is thicker, the plate body 312 drives the multiple rake nails 52 to move in the direction away from the vehicle body 1. At this time, the greater the distance between the vertical plane where the multiple rake nails 52 are located and the vertical plane where the sprocket frame 22 is located, the thicker the yam can be accommodated. Similarly, when the yam to be dug is thinner, the plate body 312 drives the multiple rake nails 52 to move in the direction close to the vehicle body 1.

The yams in the planting field are planted in rows. When in use, the vehicle body 1 is started, and the trenching mechanism 2 is moved to the side of a row of yams to be harvested, which is consistent with the arrangement direction of the yams, and then the vehicle body 1 is slowly moved forward, and the trenching mechanism 2 slowly digs a trench on the side of the row of yams. In the process of slowly digging the trench, the pressing mechanism 3 drives the loosening harrow 5 to rotate within a smaller angle range. The first mounting frame 4 is moved downward, driving the loosening rake 5 to be inserted into the side of the row of yams away from the groove, and then the driving mechanism 6 drives the loosening rake 5 to rotate slightly in the direction of the groove, pushing the row of yams mixed with the soil in the direction of the groove to loosen the soil, and then the harvesters can directly take the yams out of the groove; adopting the above method, every time the vehicle body 1 moves forward a certain distance, the trenching mechanism 2 digs a groove, and at the same time, the loosening rake 5 at the rear loosens a part of the yams mixed with the soil, making it convenient for the harvesters to harvest the yams, thereby solving the problem of low harvesting efficiency of the existing yam harvester. It should be noted that each time the vehicle body 1 drives the trenching mechanism 2 forward a certain distance, it must stop and wait for the loosening harrow 5 to be inserted into the planting field to loosen a part of the soil and yam and then move up to take them out. Only then can the vehicle body 1 continue to drive the trenching mechanism 2 forward. This is an intermittent operation. After the entire row of yams mixed with the soil is loosened toward the direction of the trench, the harvesters will take this row of yams out of the trench.
