The technical field is as follows:

the invention relates to the technical field of crop harvesting equipment, in particular to a vibration digging device for harvesting crops, which is particularly suitable for harvesting garlic.

Background art:

when crops such as garlic, onions, potatoes and the like are mature, the crops need to be harvested, and the traditional harvesting mode mainly adopts manpower. With the development of science and technology, mechanized harvesting equipment is correspondingly developed, excavation is a necessary function of the mechanized harvesting equipment, and the quality and the harvesting efficiency of the whole crops are directly influenced by the advantages and disadvantages of the design of an excavating mechanism.

The existing crop excavation is mainly realized by adopting an excavating shovel, the excavating shovel is directly fixed at the front end of a crop harvester during use, and the excavating shovel is driven by an engine to excavate forwards. Although the existing excavation mode meets the requirements of crops on excavation to a certain extent, the existing excavation mode has a plurality of defects in actual use: firstly, the excavating resistance is large, the existing excavating shovel is deeply buried underground during working and the excavating shovel is vertically immovable, so that the resistance given by soil is very large, the power of an engine is occupied, and the crop harvesting efficiency is seriously influenced; secondly, the digging shovel is easy to accumulate and block, large soil blocks are excavated due to the fact that the digging shovel is deep into the ground and does not move vertically, weeds, fallen rods, fallen leaves and other sundries on the soil are easy to accumulate, soil removal and conveying of crops are affected after accumulation, and shutdown cleaning is needed in severe cases. Therefore, it is necessary to improve the existing crop digging device, so that the digging resistance can be reduced, the accumulation and blockage can be reduced, and the harvesting efficiency and the quality of the whole machine can be improved on the premise of ensuring the digging effect.

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.

The invention content is as follows:

the invention aims to solve the problems in the prior art and provides a vibration excavating device which has the advantages of reasonable structural design, small excavating resistance, difficult accumulation and blockage, high excavating efficiency, good excavating quality and the like.

The invention adopts the following technical scheme to realize the purpose:

a vibratory excavation apparatus, comprising:

the frame is used for mounting the vibration mechanism;

the vibrating mechanism comprises a vibrating driver arranged on the rack, the vibrating driver is connected with an eccentric device arranged on the rack through belt transmission, the eccentric device is connected with a shovel arm, a digging shovel is installed at the lower end of the shovel arm, and a restraint device for restraining the movement of the shovel arm is arranged between the shovel arm and the rack.

The vibration driver is a hydraulic motor, the belt transmission comprises a belt wheel A connected with the hydraulic motor and a belt wheel B connected with the eccentric device, and the belt wheel A is connected with the belt wheel B through a conveying belt.

The digging shovel comprises a shovel blade seat, the shovel blade seat is connected with the shovel arm, and a plurality of shovel blades are arranged on the shovel blade seat.

By adopting the structure, the invention can bring the following beneficial effects:

through the design of the vibration mechanism, particularly by utilizing the eccentric vibration principle and carrying out corresponding restraint on eccentric motion, the backward throwing motion of the excavating shovel to soil can be realized, the forward motion mode of the traditional excavating shovel is changed, the forward resistance can be reduced by the design, the excavated soil can be thrown backward, the soil is loosened, and the soil is not easy to accumulate and block. The restraint device mainly plays a role in limiting the movement amplitude of the digging shovel, ensures that the digging shovel cannot go deep into the ground too deeply and cannot break away from the soil, and ensures digging and soil loosening effects.
