Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, in particular to an excavating air-blowing soil-shaking structure. Background Art

[0002] With the development of agricultural modernization, digitalization and technology, the requirements for efficiency in agricultural production are increasing. Traditional ginger harvesters simply dig out the ginger during work, resulting in a lot of soil attached to its surface. These soils not only affect the appearance of the ginger, but may also contain harmful substances such as bacteria and insect eggs, which pose a potential threat to the quality and safety of the ginger. In addition, the soil attached to the surface of the ginger will increase its weight and volume, which is not conducive to subsequent storage and transportation. The soil on the surface of the ginger may also contain impurities such as stones and tree roots, which may cause wear or damage to the harvester's knives, conveyor belts and other parts during the harvesting process. If the surface soil of the ginger is not removed during harvesting, it will take more time and manpower to remove the soil in the subsequent processing, cleaning and other processes. This not only increases the labor intensity, but also may affect the processing efficiency.

[0003] How to remove the soil attached to the surface of ginger at a low cost has become a problem faced by many agricultural machinery manufacturers. In addition, the structure must be adapted to the situation that the depth of ginger harvesting varies due to the different sowing depths of ginger in different regions. In view of the above situation, it is urgent to provide an excavation air-blowing soil-shaking structure to overcome the shortcomings in current practical applications. Summary of the invention

[0004] The utility model provides an excavating air-blowing soil-shaking structure with a simple structure, which can complete the excavating air-blowing soil-shaking work of a ginger harvester, and solves the problem that the surface soil of the existing ginger cannot be removed during harvesting, and more time and manpower are needed to remove the soil in subsequent processing, cleaning and other treatment processes, thereby increasing labor intensity and processing efficiency.

[0005] The technical solution of the utility model is described as follows in conjunction with the accompanying drawings:

[0006] An excavation air blowing soil shaking structure, installed on a harvester, comprises a frame 1, a large-diameter fan pipe 2, a depth-limiting wheel 3, an excavation shovel 4, a fan high-pressure pipe 5, a connecting rod 6, a fan 7, and a connecting rod transmission shaft 11;

[0007] The lower end of the frame 1 is fixedly connected to the depth limiting wheel 3;

[0008] The fan large-diameter pipeline 2 and the fan high-pressure pipeline 5 are welded, and the pipelines are interconnected; the air outlet of the fan 7 is connected to the fan large-diameter pipeline 2 and the fan high-pressure pipeline 5, and the pipelines are interconnected;

[0009] The fan 7 and the digging shovel 4 are fixedly connected to the frame 1; the engine of the harvester transmits power to the fan 7 and the connecting rod transmission shaft 11;

[0010] The connecting rod transmission shaft 11 is arranged on the frame 1; a connecting rod transmission shaft lifting lug 10 is arranged on the connecting rod transmission shaft 11; the connecting rod transmission shaft lifting lug 10 is movably connected to one end of the connecting rod 6 through a connecting rod.

[0011] Furthermore, the excavating shovel 4 is provided with a first welded lifting ear pair 8 and a second welded lifting ear pair 9 of the excavating shovel; one end of the first welded lifting ear pair 8 of the excavating shovel is welded and fixed to the excavating shovel 4, and the other end is movably connected to the other end of the connecting rod 6 through a connecting rod; one end of the second welded lifting ear pair 9 of the excavating shovel is welded and fixed to the excavating shovel 4, and the other end is rotatably connected to the frame 1.

[0012] Furthermore, the depth limiting wheel 3 is provided with upper and lower adjusting locking devices.

[0013] The beneficial effects of the utility model are:

[0014] The utility model adjusts the ground distance of the excavation air blowing and soil shaking structure through the depth limiting wheel. During the forward movement of the ginger harvester, the ginger is dug up by the excavating shovel, and the power of the engine is transmitted to the connecting rod mechanism and the drive shaft of the fan. The connecting rod mechanism causes the excavating shovel to vibrate, and the wind generated by the fan is blown out through the ordinary pipeline and the high-pressure pipeline. The air outlet of the high-pressure pipeline is located obliquely below the excavating shovel, and blows obliquely upward toward the excavated ginger but still in the soil, so that the soil attached to the surface of the ginger is preliminarily removed. The air outlet of the ordinary pipeline is located above the excavating shovel, so that the soil attached to the surface of the ginger that has been dug out of the soil can be further removed, thereby completing the excavation air blowing and soil shaking work of the ginger harvester.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] See also Figure 1-Figure 4 The present embodiment provides an excavation air blowing soil shaking structure, which is installed on the working parts of the harvester, including a frame 1, a large-diameter fan pipe 2, a depth limiting wheel 3, an excavating shovel 4, a fan high-pressure pipe 5, a connecting rod 6, a fan 7, and a connecting rod transmission shaft 11.

[0025] The lower end of the frame 1 is welded to the depth limiting wheel 3; the depth limiting wheel 3 is provided with an upper and lower adjustment locking device for controlling the ground clearance of the frame 1. The upper and lower adjustment locking device can adopt a combined structure of a lead screw, an adjustment sleeve, and an existing tightening device, and the ground clearance of the frame is adjusted by rotating the adjustment sleeve to cooperate with the lead screw, and the depth limiting wheel is locked by the tightening device.

[0026] The fan large-diameter pipeline 2, the fan high-pressure pipeline 5 and the fan 7 are all fixed on the frame 1; the fan large-diameter pipeline 2 is welded to the pipeline wall of the fan high-pressure pipeline 5, and the pipelines are connected; the air outlet of the fan 7 is welded to the fan large-diameter pipeline 2, and the pipelines are connected.

[0027] The air outlet of the large-diameter pipe 2 of the fan is used to remove soil from the ginger dug out of the ground.

[0028] The air outlet of the fan high-pressure pipe 5 is used to blow the air toward the surface of the ginger that has not been separated from the soil.

[0029] The connecting rod 6 is movably connected to the digging shovel 4; the engine of the harvester transmits power to the fan 7 and the connecting rod transmission shaft 11 through a transmission system (not shown in the figure) using chains and sprockets.

[0030] The connecting rod transmission shaft 11 is arranged on the corresponding hole position of the frame 1; a connecting rod transmission shaft lifting ear 10 is sleeved on the connecting rod transmission shaft 11; and the connecting rod transmission shaft lifting ear 10 is movably connected to one end of the connecting rod 6.

[0031] The excavating shovel 4 is fixed with a first welded lifting ear pair 8 and a second welded lifting ear pair 9 of the excavating shovel; one end of the first welded lifting ear pair 8 of the excavating shovel is welded and fixed to the excavating shovel 4, and the other end is movably connected to the other end of the connecting rod 6 through a connecting rod; one end of the second welded lifting ear pair 9 of the excavating shovel is welded and fixed to the excavating shovel 4, and the other end is rotatably connected to the frame 1.

[0032] The digging shovel 4 has a handle that appropriately reduces the area while ensuring strength, thereby reducing the working resistance encountered by the ginger harvester during digging.

[0033] See also Figure 5 , the working principle of the utility model is as follows:

[0034] Before the ginger harvester is operated, the distance of the frame 1 from the ground is controlled by adjusting the depth-limiting wheel 3 to meet the different requirements of ginger harvesting depth in different regions. The engine of the ginger harvester transmits power to the fan 7 and the connecting rod transmission shaft 11 through a transmission system. The connecting rod transmission shaft 11 rotates and pulls the connecting rod 6 to drive the digging shovel 4, so that the digging shovel 4 shakes around the second welding ear pair 9 of the digging shovel, and the digging shovel vibrates and initially removes soil from the ginger. At the same time, the fan 7 blows high-pressure air from the fan high-pressure pipe 5 to the surface of the ginger that has not been separated from the soil, and the fan 7 initially removes soil from the ginger. As the ginger harvester continues to move forward, the ginger is dug out of the ground, and at the same time, the fan large-diameter pipe 2 blows air to the ginger dug out of the ground, further removing soil from the ginger, thereby completing the digging air blowing and shaking soil work.
