Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a potato crop harvester for moist soil environments. Background Technology

[0002] Tubers, such as potatoes and sweet potatoes, are root and tuber crops whose main vegetative organs (tubers or roots) generally grow in the soil. Therefore, these crops need to be dug out of the soil and harvested. Currently, tuber harvesting machines have gradually replaced traditional manual harvesting and have become key equipment in large-scale planting. Existing tuber harvesting machines typically consist of a frame, a digging shovel, and a conveying assembly. The digging shovel digs the tubers out of the soil, and the conveying assembly lifts and transports them to the back of the frame for harvesting, significantly improving harvesting efficiency.

[0003] However, in practice, if the tuber crops encounter rainfall before harvest, or if the soil moisture increases significantly due to other reasons, the soil stickiness will increase greatly. The amount of soil adhering to the surface of the tuber crops will increase and it will be difficult to separate the soil from the tuber crops. Not only will some tuber crops be missed in the subsequent sorting process due to soil covering, but it will also increase the workload and labor cost of subsequent manual cleaning. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a potato crop harvester for moist soil environments. By adding a vibration component, the vibration of the potato crop breaks the adhesion between the surface of the potato crop and the soil, thereby removing the soil from the surface of the potato crop, improving the cleanliness of the harvested potato crop, and reducing the workload and labor costs of subsequent manual sorting and cleaning.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A potato crop harvester for moist soil environments includes a frame and a digging shovel and a conveying assembly located on the frame. The digging shovel is located at the front end of the frame, and its end is connected to the input end of the conveying assembly. The potato crop is lifted upward along the conveying assembly and falls to the rear of the frame. A vibration assembly is added to the frame, and the conveying assembly vibrates with the help of the vibration assembly. The potato crop vibrates on the conveying assembly with the help of the vibration assembly.

[0007] The conveying assembly includes conveyor belts and conveyor rollers. The conveyor belts are symmetrically arranged on both sides of the frame, and multiple conveyor rollers are distributed at equal intervals between the two conveyor belts along the conveying direction.

[0008] The vibration assembly includes a vibrating leaf spring disposed below the conveying assembly. The fixed end of the vibrating leaf spring is fixedly connected to the frame, and the free end of the vibrating leaf spring is located on the rotation path of the lower conveying roller. The conveying roller vibrates by means of the impact of the vibrating leaf spring.

[0009] The vibration assembly also includes a vibration slider disposed at the free end of the vibration leaf spring. The vibration slider has a wedge-shaped block structure, and the inclined surface of the vibration slider faces the input side of the conveyor roller.

[0010] The length of the inclined surface of the vibrating slider is equal to the distance between adjacent conveying rollers.

[0011] The digging shovel has a "Λ" shaped structure, with the middle part of the shovel protruding upwards and the front end of the shovel having a sharp blade-like structure.

[0012] The height difference between the protruding top of the digging shovel and the two side edges of the digging shovel is 2-5cm.

[0013] The end of the frame is equipped with a buffer slide plate, which has an arc-shaped structure. One end of the buffer slide plate is connected to the output end of the conveying component, and the other end of the buffer slide plate is suspended above the soil in an inclined direction. The tuber crop rolls down the buffer slide plate onto the soil behind the frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model adds a vibration component, which causes the conveying component to vibrate, so that the tuber crop vibrates synchronously on the conveying component. The vibration of the tuber crop breaks the adhesion between the surface of the tuber crop and the soil, thereby causing the soil to detach from the surface of the tuber crop, improving the cleanliness of the tuber crop after harvesting, reducing the workload and labor costs of subsequent manual sorting and cleaning, and avoiding the problem of missed harvesting due to soil covering the tuber crop, thus improving the harvest rate of tuber crop.

[0016] 2. The conveying component in this utility model does not require an additional power source. It can achieve vibration by relying solely on the rotation of the conveying roller itself. It has a simple structure, strong durability, can adapt to the harsh environment of humid fields, and has low maintenance costs.

[0017] When the upper-level conveyor roller rotates with the conveyor belt and comes into contact with the free end of the vibrating leaf spring, the upper-level conveyor roller will press down on the vibrating leaf spring and cause it to bend. As the conveyor roller continues to rotate, the vibrating leaf spring will disengage from the pressing of the upper-level conveyor roller and will quickly rebound, generating a reverse impact force on the lower-level conveyor roller. The vibration of the conveyor roller will be transmitted to the entire conveying assembly through the conveyor belt, so that the potato crop is simultaneously subjected to vibration during the conveying process, thereby causing the soil on the surface of the potato crop to fall off.

[0018] 3. This utility model adds an upward protrusion structure to the middle part of the digging shovel. The protruding middle part can guide the dug-out soil-potato mixture to both sides of the digging shovel, avoiding the accumulation of potato crops and soil in the middle of the digging shovel. At the same time, the middle part can also play a diversion role, allowing some loose and moist soil to slide off from both sides of the digging shovel, playing a preliminary soil discharge role and reducing the amount of soil entering the conveying component.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] Specific embodiments, such as Figure 1-2 As shown, a potato crop harvester for moist soil environments includes a frame 1, a digging shovel 2 and a conveying assembly located on the frame 1. The digging shovel 2 is located at the front end of the frame 1, and the end of the digging shovel 2 is connected to the input end of the conveying assembly. The potato crop is lifted upward along the conveying assembly and falls to the rear of the frame 1. A vibration assembly is added to the frame 1, and the conveying assembly vibrates with the help of the vibration assembly. The potato crop vibrates on the conveying assembly with the help of the vibration assembly.

[0027] If rainfall occurs just before the harvest of tuber crops, or if soil moisture increases significantly for other reasons, the soil will become much stickier. This will increase the amount of soil adhering to the surface of the tuber crops and make it difficult to separate them from the crops. Not only will some tuber crops be missed during the subsequent sorting process due to soil coating, but it will also increase the workload and labor costs of subsequent manual cleaning.

[0028] The harvester of this invention is suitable for harvesting underground tuber crops such as potatoes and sweet potatoes. By adding a vibration component, the conveying component vibrates, causing the tuber crops to vibrate synchronously on the conveying component. The vibration of the tuber crops breaks the adhesion between the surface of the tuber crops and the soil, thereby removing the soil from the surface of the tuber crops, improving the cleanliness of the harvested tuber crops, reducing the workload and labor costs of subsequent manual sorting and cleaning, and avoiding the problem of missed harvesting due to soil covering the tuber crops, thus improving the harvest rate of tuber crops.

[0029] In addition, the periodic vibration of the conveying components will cause the soil adhering to the surface of the conveying components to fall off, preventing problems such as equipment jamming and component wear caused by a large amount of soil adhering to the conveying components, thus extending the service life of the equipment.

[0030] like Figure 1-2 As shown, the conveying assembly includes a conveyor belt 3 and conveyor rollers 4. The conveyor belts 3 are symmetrically arranged on both sides of the frame 1, and multiple conveyor rollers 4 are distributed at equal intervals between the two conveyor belts 3 along the conveying direction.

[0031] The gap between the conveyor rollers 4 can serve as a soil discharge channel, allowing the soil stripped from the surface of the potato crop to fall directly through the gap without the need for additional soil discharge structures.

[0032] like Figure 1-4 As shown, the vibration assembly includes a vibrating leaf spring 5 disposed below the conveying assembly. The fixed end of the vibrating leaf spring 5 is fixedly connected to the frame 1, and the free end of the vibrating leaf spring 5 is located on the rotation path of the lower conveying roller 4. The conveying roller 4 vibrates by means of the impact of the vibrating leaf spring 5.

[0033] like Figure 3 As shown, when the upper-level conveyor roller 4 rotates with the conveyor belt 3 and comes into contact with the free end of the vibrating leaf spring 5, the upper-level conveyor roller 4 presses down on the vibrating leaf spring 5 and causes it to bend; as the conveyor roller 4 continues to rotate, the vibrating leaf spring 5 disengages from the pressure of the upper-level conveyor roller 4, as... Figure 4 As shown, the vibrating leaf spring 5 will rebound quickly, generating a reverse impact force on the next stage conveyor roller 4. The vibration of the conveyor roller 4 will be transmitted to the entire conveying assembly through the conveyor belt 3, so that the potato crop is simultaneously subjected to vibration during the conveying process, thereby causing the soil on the surface of the potato crop to fall off.

[0034] In addition, this structure does not require an additional power source; it can achieve vibration simply by rotating the conveyor roller 4 itself. The vibrating leaf spring 5 has a simple structure, is durable, adaptable to the harsh environment of wet fields, and has low maintenance costs.

[0035] like Figure 3-4As shown, the vibration assembly also includes a vibration slider 6 disposed at the free end of the vibration leaf spring 5. The vibration slider 6 has a wedge-shaped block structure, and the inclined surface of the vibration slider 6 faces the input side of the conveying roller 4.

[0036] The smooth transition of the inclined surface of the vibration slider 6 can reduce the wear of the components and also avoid mechanical damage to the conveyor roller 4 caused by the leaf spring directly striking the conveyor roller 4.

[0037] The length of the inclined surface of the vibrating slider 6 is equal to the distance between adjacent conveying rollers 4.

[0038] As soon as the previous conveyor roller 4 disengages from the vibrating slider 6, the next conveyor roller 4 enters the swing range of the vibrating slider 6 and is struck by the vibrating slider 6, forming a continuous periodic vibration trigger, thereby avoiding vibration gaps and ensuring the separation effect between the potato crop and the soil.

[0039] like Figure 1 and Figure 5 As shown, the digging shovel 2 has a "Λ" shaped structure, with the middle part of the digging shovel 2 protruding upwards and the front end of the digging shovel 2 having a sharp blade-like structure.

[0040] The blade-like structure at the front end of the digging shovel 2 reduces its resistance to soil penetration, making it easier for the digging shovel 2 to penetrate deeper into the soil layer. The raised middle section guides the excavated soil-potato mixture to both sides of the digging shovel 2, preventing the accumulation of potato crops and soil in the middle of the digging shovel 2; at the same time, the middle section also acts as a diversion, allowing some loose, moist soil to slide off from both sides of the digging shovel 2, playing a preliminary role in soil removal and reducing the amount of soil entering the conveying components.

[0041] The height difference between the protruding top of the excavator shovel 2 and the two side edges of the excavator shovel 2 is 2-5cm.

[0042] The slope of the digging shovel 2 should not be too steep. If the slope is too steep, the tuber crop may roll down the inclined surface of the digging shovel 2, resulting in missed harvesting.

[0043] like Figure 2 As shown, a buffer slide plate 7 is provided at the end of the frame 1. The buffer slide plate 7 has an arc-shaped structure. One end of the buffer slide plate 7 is connected to the output end of the conveying component, and the other end of the buffer slide plate 7 is suspended above the soil in an inclined direction. The potato crop rolls down the buffer slide plate 7 onto the soil behind the frame 1.

[0044] In humid environments, the skin of tuber crops is fragile. If they fall directly from the output end of the conveyor assembly to the ground, the impact can easily cause damage to their skin. The buffer slide 7 shortens the path and time of the tuber crops' free fall in the vertical direction, thereby reducing the impact force on the tuber crops upon landing and protecting them.
