Technical Field

[0001] The utility model relates to the technical field of potato harvester equipment, in particular to a new type of hand-held direct-connected potato harvester. Background Art

[0002] A hand-held direct-connected potato harvester is an agricultural machine specifically used for harvesting potatoes. The hand-held direct-connected potato harvester usually uses a walking tractor to provide power, and transmits the power to the digging component through a transmission device. The digging component digs out the potatoes buried in the soil and conveys them to a separation device. The separation device separates the potatoes from impurities such as soil and weeds, so that the potatoes can be smoothly collected into a collection box.

[0003] The main characteristics of the hand-held direct-connected potato harvester include: (1) Simple operation: The hand-held direct-connected design makes the operation flexible and suitable for harvesting operations on small plots of land and complex terrains. (2) High efficiency: It can quickly dig and separate potatoes, improve the harvesting efficiency, and save labor costs. (3) Less damage: Adopt a reasonable digging and separation method to reduce the damage to potatoes and ensure the harvesting quality. (4) Strong adaptability: It can be adjusted according to different soil conditions and potato planting densities to meet different harvesting requirements.

[0004] During the working process of the existing potato harvester, the potatoes are conveyed through a conveying unit, but only through the vibration of the elastic conveying cable during the conveying process, it is impossible to effectively screen out the soil blocks attached to the surface of the potatoes, which affects the harvesting quality of the potatoes and there are more soil block impurities.

The driving shaft is driven to rotate by a motor, and the rotation of the driving wheel drives the first driven wheel and the first driven shaft to rotate. The rotation of the first driven shaft drives the second driven shaft to rotate;

[0010] The first support shaft and the second support shaft are respectively rotatably connected to the frame.

[0012] A material pushing block is arranged on the first driven shaft. The material pushing block protrudes from the first driven shaft and is arranged at intervals along the axial direction of the first driven shaft. The material pushing block is made of rubber.

[0013] Furthermore, the material pushing block is connected to the outer wall of the first driven shaft in a pasting manner.

[0014] Furthermore, the driving shaft, the first driven shaft, the second driven shaft, the first support shaft, and the second support shaft are arranged parallel to each other.

[0015] Furthermore, the first conveyor belt and the second conveyor belt include multiple elastic belts.

[0016] Furthermore, a front shovel is arranged on one side of the frame close to the connecting rod.

[0017] Compared with the related technologies, a novel walking-behind direct-connected potato harvester proposed by the present utility model has the beneficial effects that: through the rotation of the drive shaft, the first driven shaft, the second driven shaft, the drive wheel, the first driven wheel and the second driven wheel, the rotation drives of the first conveyor belt and the second conveyor belt are respectively realized, thereby realizing the stepped double-layer conveying drive.

Furthermore, a material deflecting block is arranged on the first driven shaft, so that when the potatoes pass through the first driven shaft, the soil blocks can be peeled off under the driving action of the material deflecting block, and thus the soil blocks attached to the surface of the potatoes can be peeled off and removed.

[0020] The present utility model will be further described in detail below with reference to the drawings and the specific embodiments.

[0021] Referring to the attached Figure 1-2 As shown in the figure, the present utility model proposes a novel walking-behind direct-connected potato harvester, which includes a frame 11, a connecting rod 12, a drive shaft 21, a first driven shaft 22, a second driven shaft 23, a first support shaft 24, a second support shaft 25, a drive wheel 31, a first driven wheel 32, a second driven wheel 33, a first conveyor belt 41 and a second conveyor belt 42. The drive shaft 21, the first driven shaft 22, the second driven shaft 23, the first support shaft 24 and the second support shaft 25 are arranged in parallel.

[0022] The connecting rod 12 is fixedly arranged at the front end of the frame 11. The connecting rod 12 is used to connect the tractor equipment, and the tractor equipment realizes the drive of the potato harvester. A front shovel 13 is arranged on one side of the frame 11 close to the connecting rod 12. During the movement of the potato harvester, the potatoes are driven by the front shovel and conveyed to the first conveyor belt 41, and then conveyed to the second conveyor belt 42 by the first conveyor belt 41, thereby realizing the harvesting of the potatoes.

[0023] Both ends of the drive shaft 21 are rotatably connected to the frame 11. One end of the drive wheel 31 is fixedly connected to the drive wheel 31. Both ends of the first driven shaft 22 are rotatably connected to the frame 11. One end of the first driven wheel 32 is fixedly connected to the first driven wheel 32. Both ends of the second driven shaft 23 are rotatably connected to the frame 11. One end of the second driven wheel 33 is fixedly connected to the second driven wheel 33.

[0024] The drive wheel 31 and the first driven wheel 32 are connected by a belt. The first driven wheel 32 and the second driven wheel 33 are connected by a belt. The drive shaft 21 is driven to rotate by a motor and drives the first driven wheel 32 and the first driven shaft 22 to rotate through the rotation of the drive wheel 31. The rotation of the first driven shaft 22 drives the second driven shaft 23 to rotate.

[0025] The first support shaft 24 and the second support shaft 25 are respectively rotatably connected to the frame 11. A first conveyor belt 41 is connected between the first support shaft 24 and the first driven shaft 22. A second conveyor belt 42 is connected between the second support shaft 25 and the second driven shaft 23. The first conveyor belt 41 and the second conveyor belt 42 include a plurality of elastic belts 43.

[0026] The first driven shaft 22 is located above the second support shaft 25 and the first support shaft 24. The first driven shaft 22 is located between the first support shaft 24 and the second driven shaft 23. The first driven shaft 22 is closer to the connecting rod 12 than the second driven shaft 23. Thus, the first conveyor belt 41 and the second conveyor belt 42 can both be arranged obliquely, and the first conveyor belt 41 is arranged near the front end of the frame 11. The rotation of the drive shaft 21, the first driven shaft 22, the second driven shaft 23 and the drive wheel 31, the first driven wheel 32 and the second driven wheel 33 respectively realizes the rotational drive of the first conveyor belt 41 and the second conveyor belt 42, thereby realizing the stepped double-layer conveying drive.

[0027] A material pusher 221 is arranged on the first driven shaft 22. The material pusher 221 protrudes from the first driven shaft 22 and is arranged at intervals along the axial direction of the first driven shaft 22. The material pusher 221 is connected to the outer wall of the first driven shaft 22 in a pasting manner. The material pusher 221 is made of rubber material, thereby improving the friction efficiency and effect of the material pusher 221 on the soil blocks.

[0028] As the first driven shaft 22 for achieving the transmission function is located at the intermediate position between the first conveyor belt 41 and the second conveyor belt 42, the potatoes after passing through the first conveyor belt 41 fall onto the second conveyor belt 42 via the first driven shaft 22 for conveying. Furthermore, a material deflecting block 221 is provided on the first driven shaft 22, so that when the potatoes pass through the first driven shaft 22, the soil blocks can be peeled off under the driving action of the material deflecting block 221, thereby realizing the peeling and removal of the soil blocks attached to the surface of the potatoes. Thus, it is possible to realize the removal and separation of the soil blocks without additionally setting up power components or units, improving the harvesting quality of the potatoes.
