The harvester is simple in structure, the frame is provided with the engine drive, power is not provided by the outside, the harvester can be operated by one person, and high working efficiency is kept. The scraper bucket is rotationally dug into the ridge pile, the running track of the scraper bucket is fixed, and the soil inlet depth is stable, so that sweet potatoes are not easy to damage, and the scraper bucket does not need to be designed to be excessively heavy.

As the improvement of the utility model, the scraper bowl has 2 ~ 4, along the different direction of the radial orientation of pivot. The rotating speed of the bucket is generally low, sufficient falling time of sweet potatoes carried by the bucket is ensured, the sweet potatoes are not rotated back to the ground along with the bucket, and a plurality of buckets are adopted, so that high digging frequency can be kept at a low rotating speed. Further, the bucket shanks are integrally connected to each other. Further, the number of the buckets is 2, and the radial directions of the buckets along the rotating shaft are opposite.

In order to ensure that the bucket has enough capacity and is convenient for digging up the whole ridge pile at one time, the middle part of the bucket is concave, and the transition surface from the middle part to the edge is an inclined surface or a cambered surface. The inclined surface or the cambered surface ensures that the dug sweet potatoes and soil easily slide out under the action of inertia. In order to reduce the stress of the bucket in the process of entering the ridge pile, the bucket is in the shape of narrow front and back and wide middle, and the front edge is in the shape of a circular arc, so that the damage to sweet potatoes is reduced. Furthermore, a discharge opening is formed in the rear portion of the bucket, when the bucket rotates to the horizontal position and continues to rotate upwards, the lifted sweet potatoes and soil fall out of the discharge opening, and the time and the position of the sweet potatoes are effectively controlled.

As a further improvement of the utility model, a net bag is arranged on the frame behind the bucket. After the sweet potatoes and soil dug by the bucket fall into the net bag, the soil is removed from the meshes in the moving process of the digging machine, so that the effect of separating the soil from the sweet potatoes is achieved. A net port can be formed in the bottom of the net bag, sweet potatoes are discharged from the net port in the advancing process of the digging machine, the digging machine does not need to be stopped to manually take out the sweet potatoes from the net port, continuous work of the digging machine is facilitated, multiple workers can work in a division manner conveniently, and efficiency is improved.

The drive mechanism is preferably a chain drive comprising a chain, a drive sprocket and a driven sprocket.

In order to facilitate parking and increase safety, the rear part of the frame is provided with support legs.

The beneficial effects of the utility model reside in that:

to sum up, the utility model discloses simple structure is light, and is single can operate, from taking power device, does not rely on outside machinery to provide power, and keeps high work efficiency.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

Fig. 1 is the utility model discloses a structural schematic diagram, the utility model provides a sweet potato harvester, including frame 1, dress engine 2 on the frame, wheel 4, brake valve lever 8, with the reducing gear box 3 of engine 2 hookup, with the drive mechanism 5 of reducing gear box 3 hookup, with the scraper bowl 7 of drive mechanism 5 hookup scraper bowl 7 through the pivot with frame 1 hookup.

When the sweet potato harvester is used, the control handle 8 is held by hand for control, when the sweet potato harvester is started on the sweet potato ridge pile, the bucket 7 rotates to dig into the ridge pile from the front, sweet potatoes are dug out from the rear, the harvester continues to push forward for continuous work, the working efficiency is high, and the labor intensity of manpower is reduced.

The bucket 7 can be one or more, when a plurality of buckets 7 are arranged, the buckets 7 can be connected to the rotating shaft side by side or connected into a whole by the handle, and can be oriented in different directions or in one direction along the radial direction of the rotating shaft. Preferably, the number of the buckets 7 is 2-4, and the buckets face different directions along the radial direction of the rotating shaft, so that the radial force of the rotating shaft is reduced, and the load fluctuation range of the engine 2 is also reduced as much as possible. The speed of rotation of the bucket 7 is generally low, and it is necessary to ensure that the scooped sweet potatoes have sufficient time to fall without rotating back to the ground with the bucket 7. With a plurality of buckets 7, a higher digging frequency can be maintained at a slower rotational speed. Further, the respective bucket 7 shanks are integrally connected to each other. Further, the number of the buckets 7 is 2, and the direction is opposite.

As shown in fig. 2 to 3, which are schematic structural views of the bucket 7, the middle of the bucket 7 is concave, and a transition surface from the middle to the edge is an inclined surface or an arc surface. This setting has increased the capacity of scraper bowl 7, is convenient for pile whole ridge once only to dig, and the inclined plane also makes the sweet potato and the earth that are dug easy roll-off under inertial effect simultaneously. In order to reduce the stress of the bucket 7 in the process of entering the ridge pile, the bucket 7 is further in the shape of being narrow in the front and the rear and wide in the middle, and the front edge is in the shape of a circular arc. Furthermore, the rear part of the bucket 7 is provided with a discharge opening, when the bucket 7 rotates to the horizontal position and continues to rotate upwards, the lifted sweet potatoes fall out from the discharge opening 7a, and the time and the position of the sweet potatoes are effectively controlled.

As an improvement of the other aspect of the utility model, the frame 1 is further provided with a net bag 9 at the rear of the bucket. After the sweet potatoes and soil dug by the bucket 7 fall into the net bag 9, the soil is removed from the meshes in the propelling process of the digging machine, so that the effect of separating the soil from the sweet potatoes is achieved. A net port can be formed in the bottom of the net bag 9, sweet potatoes are discharged from the net port in the advancing process of the digging machine, the digging machine does not need to be stopped to manually take out the sweet potatoes from the net port, continuous work of the digging machine is facilitated, multiple persons can work in a division manner conveniently, and efficiency is improved.

The transmission 5 is preferably a chain drive comprising a chain 6, a driving sprocket 6a and a driven sprocket 6 b.

As shown in figure 1, the rear part of the frame 1 is provided with a support leg 1 for the convenience of parking and increasing safety.

The engine 2 may be a diesel engine, an electric motor, or the like. The transmission mechanism 5 can also adopt other structures, such as: the belt transmission, the gear box which is arranged on the rotating shaft of the bucket 7 and the rotating shaft of the reduction gearbox 3 respectively, the gear shaft transmission and the like are adopted.
