[0002] my country is the country with the largest ginger planting area and the largest total production in the world. As a daily condiment and a high-value Chinese medicinal material, ginger has the functions of dispelling cold, warming the lungs and relieving cough, and detoxifying, and has good economic benefits. At present, my country's ginger production scale and export trade

[0003] China still leads the world in ginger production. However, in the face of growing market demand, ginger harvesting in my country is still primarily done manually. Manual harvesting is labor-intensive, inefficient, costly, and prolongs the harvest period, making it uneconomical for large-scale harvesting. Manual harvesting involves loosening the soil with a shovel or fork, pulling out the ginger, cutting the stems, and finally boxing it. However, the current level of mechanized ginger production in China is low, with only certain operational steps being mechanized. This makes it difficult to efficiently complete tasks such as digging and vibrating the ginger, gripping and conveying it, soil removal, separating the ginger stalks and pieces, and conveying and boxing the pieces (with manual assistance). Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides an intelligent, high-efficiency, and low-loss ginger combine harvester and a method for using the same.

[0005] The present invention is achieved through the following technical solutions, which provide an intelligent, efficient and low-loss ginger combine harvester, including a frame, a digging mechanism and a clamping, conveying and cutting mechanism. The bottom of the frame is equipped with a crawler walking mechanism. The digging mechanism includes a lifting platform frame hinged at the front end of the frame and a tilting cylinder that drives the lifting platform frame to swing up and down. The lifting platform frame is equipped with a soil-breaking shovel and a soil-shaking shovel arranged front and back.

The stem conveying belts move in a circular motion and the side of the two stem conveying belts that are close to each other are moved backward and upward. A fixed controllable airbag is provided on the back of the side of the two stem conveying belts that are close to each other.

[0006] As an optimization, the earth-breaking shovel includes two shovel blades arranged on the left and right, and the two shovel blades are arranged in a V shape and the spacing between them gradually decreases from top to bottom.

[0007] As an optimization, the soil shaking shovel is hinged to the soil breaking shovel through a soil shaking connecting rod, a soil shaking shovel motor is installed on the lifting platform frame, and a crank hinged to the upper end of the soil shaking shovel is fixed on the rotating shaft of the soil shaking shovel motor.

[0008] As an optimization, the front end of the lifting platform frame is fixedly connected to a limited depth wheel support frame, and the lower end of the limited depth wheel support frame is equipped with a limited depth wheel.

[0009] As an optimization, the counter-rotating extracting device includes two extracting rollers arranged left and right and an extracting roller motor driving the two extracting rollers to rotate.

[0010] As an optimization, an aligned seedling cutting device is provided below the stem conveying belt, and the aligned seedling cutting device includes two guide plates, and a gap is provided between the two guide plates for allowing the ginger stems to pass through.

[0011] As an optimization, the guide plate is an arc-shaped plate, and the lower end surface of the guide plate is fixedly connected to a rubber pad of the alignment device.

[0016] b. The counter-rotating pulling device pulls the ginger stalks from the soil to the stalk conveyor belt;

[0017] c. The stalk conveyor belt transports the ginger stalks backward and upward. By adjusting the internal pressure of the controllable airbag, the clamping force at the front end of the two stalk conveyor belts is maximized to ensure that the ginger can effectively enter the clamping and conveying area. The clamping force is reduced in the middle of the two stalk conveyor belts. The clamping force is minimized when the two stalk conveyor belts reach the seedling cutting device, ensuring that the stalks can be effectively detached and the continuity of the harvesting process is guaranteed.

[0032] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0033] like Figures 1 to 9 As shown, the intelligent, efficient, and low-loss ginger combine harvester of the present invention comprises a frame, a digging mechanism, a gripping, conveying, and cutting mechanism, and a transport and collection mechanism. The frame in this embodiment comprises left and right frames, a cross frame, and a tail frame. A crawler mechanism 25 is mounted at the bottom of the frame. A battery pack 6 and a controller assembly 5 are also mounted on the frame. An ultrasonic sensor 18 is mounted at the front end of the frame to detect data such as the planting width of the ginger ahead.

[0034] The crawler track mechanism 25 is located on both sides of the bottom of the frame. It includes supporting rollers 1, supporting roller brackets 2, wheel hub motors 3, drive wheel brackets 4, drive wheels, and crawler tracks. The wheel hub motors 3 drive the drive wheels forward, which in turn transmits power to the supporting rollers 1 to achieve forward movement. The crawler track mechanism 25 described here uses pure electric technology, with motors installed in each working part of the entire machine to provide power, thereby ensuring the movement and control of the equipment.

[0035] The excavating mechanism includes a lifting platform frame 17 hinged at the front end of the frame and a tilting cylinder 16 that drives the lifting platform frame 17 to swing up and down. The rear end of the lifting platform frame 17 is hinged to the front end of the frame, and the two ends of the tilting cylinder 16 are hinged to the frame and the lifting platform frame 17 respectively. The extension and retraction of the tilting cylinder 16 is linked to the ultrasonic sensor 18, so that the upper and lower positions of the excavating mechanism are adjusted according to the detection data of the ultrasonic sensor 18.

[0036] The front end of the lifting platform frame 17 is fixedly connected to the depth limiting wheel support frame 32, and the lower end of the depth limiting wheel support frame 32 is equipped with a depth limiting wheel 22. The depth limiting wheel support is provided with a plurality of vertically arranged height adjustment holes, and the depth limiting wheel is installed on the depth limiting wheel support through the height adjustment holes.

[0037] The lifting platform frame 17 is equipped with a soil breaking shovel 20 and a soil shaking shovel 21 arranged in front and back. In this embodiment, the lifting platform frame 17 is equipped with two groups of soil breaking shovels 20 and soil shaking shovels 21 arranged side by side, so that two rows of ginger can be harvested simultaneously.

[0038] like Figure 1 、 2 As shown, the soil-breaking shovel 20 includes two shovel blades arranged in a V-shape with the spacing gradually decreasing from top to bottom. During operation, the soil-breaking shovel is inserted into the soil on both sides of the ginger, breaking up the soil as the combine harvester moves, thereby facilitating subsequent digging of the ginger.

[0039] The soil shaking shovel 21 is provided with a plurality of side-by-side soil shaking metal bars, and the soil shaking shovel moves under the ginger to dig out the ginger and shake off the soil attached to the ginger.

[0040] like Figure 5 As shown, the soil-shaking shovel 21 is hinged to the soil-breaking shovel 20 through a soil-shaking connecting rod. Figure 5 The inclined structural member connecting the middle soil shaking shovel 21 and the soil breaking shovel 20 is a soil shaking connecting rod. The front end of the soil shaking connecting rod is hinged to the soil breaking shovel 20, and the rear end is hinged to the soil shaking shovel 21, thereby realizing the shaking of the soil shaking shovel 21.

[0041] To provide a driving force for the shaking motion, a shovel motor 34 is mounted on the lifting platform frame 17. A crank, hinged to the upper end of the shovel 21, is fixedly connected to the rotating shaft of the shovel motor 34. One end of the crank is fixedly connected to the rotating shaft of the shovel motor 34, and the other end is hinged to the upper end of the shovel 21, thereby driving the upper end of the shovel 21 to swing, thereby achieving the shaking motion of the entire shovel.

[0042] The clamping, conveying, and cutting mechanism is the primary operating unit of the present invention. The conveying mechanism support frame 11 serves as its essential support component. The height of the conveying mechanism support frame 11 is adjustable, thereby adjusting the height of the clamping, conveying, and cutting mechanism. In this embodiment, two sets of clamping, conveying, and cutting mechanisms are provided, allowing for simultaneous harvesting of two rows of ginger. The two conveying mechanism support frames 11 are connected by a transmission mechanism support frame connecting rod 14.

[0043] The clamping, conveying and cutting mechanism includes two stem conveying belts 10 arranged left and right. The stem conveying belts 10 are wound between the driven roller 31 and the active roller 30 arranged front and back. The driven roller 31 and the active roller 30 are rotatably connected to the connecting support frame 12. The active roller 30 is driven to rotate by the clamping conveying mechanism motor 35 to realize the movement of the stem conveying belt 10. The stem conveying belts 10 move in a circular motion and the sides of the two stem conveying belts 10 that are close to each other move backward and upward.

[0044] like Figure 6 、 7 As shown, a fixed controllable airbag 29 is provided on the back side of the two stalk conveyor belts 10 that are close to each other. The controllable airbag 29 is mounted on the connecting support frame 12. By controlling the air pressure inside the controllable airbag 29, the clamping force between the two stalk conveyor belts 10 can be controlled. In addition, multiple controllable airbags 29 are provided along the conveying direction of the stalk conveyor belts 10, so that the clamping force of different conveying areas can be controlled separately.

[0045] The clamping, conveying and cutting mechanism also includes a counter-rotating pulling device 19 located in front of the stem conveying belt 10. The counter-rotating pulling device 19 includes two pulling rollers arranged left and right and a pulling roller motor that drives the two pulling rollers to rotate. The rotating shafts of the pulling rollers extend forward and backward, and the sides of the two pulling rollers that are close to each other rotate upward, thereby pulling the ginger stems from the soil to the stem conveying belt 10.

[0046] The clamping, conveying and cutting mechanism also includes a cutting device 13 and an alignment cutting device 9 located below the stem conveying belt 10. The alignment cutting device 9 includes two guide plates with a gap between the two guide plates for the ginger stems to pass through. The front end of the gap is relatively close to the upper and lower distance of the stem conveying belt 10, and the rear end gradually moves away from the stem conveying belt 10. Figure 8 The guide plate is an arc-shaped plate, which facilitates guiding the ginger stem to the middle position. The lower end surface of the guide plate is fixed with an alignment device rubber pad 36 to play a buffering role and prevent damage to the ginger.

[0047] The seedling cutting device 13 includes a cutting blade motor 27 and a cutting blade 26 mounted on the rotating shaft of the cutting blade motor 27. The cutting blade 26 is mounted above the gap between the two guide plates. One cutting blade 26 is located on one side of the gap, and the cutting blade motor 27 drives the cutting blade 26 to rotate. Two cutting blades 26 are located on the other side, arranged one above the other. The cutting blade 26 on one side is inserted between the two cutting blades 26 on the other side, ensuring that any rising stems passing through the gap are completely cut.

[0048] The transport and collection device includes a ginger block collection box 7, a ginger block collector 8, and a walkway 15. The ginger block collector 8 is located below the seedling cutting device 13 and is arranged on the walkway 15. The ginger block collection box 7 is arranged behind the ginger block collector 8. The ginger block collector 8 is powered by a ginger block collector motor 33. The ginger block collector can be a conveyor belt or a vibrating screen. Finally, the ginger blocks are collected manually, and the large ginger stalks will fall directly to one side of the field for easy collection and sorting.

[0049] A method for using an intelligent, efficient, and low-loss ginger combine harvester comprises the following steps:

[0050] a. Insert the soil-breaking shovel 20 into the soil on both sides of the ginger, breaking up the soil as the combine harvester moves, and then insert the soil-shaking shovel 21 under the ginger to shake it out of the soil;

[0051] b. The counter-rotating extraction device 19 pulls the ginger stalks from the soil to the stalk conveyor belt 10;

[0052] c. The stalk conveying belt 10 conveys the ginger stalks backward and upward. By adjusting the internal pressure of the controllable airbag 29, the clamping force at the front end of the two stalk conveying belts 10 is maximized to ensure that the ginger can effectively enter the clamping and conveying area. The clamping force is reduced in the middle of the two stalk conveying belts 10. The clamping force is minimized when the two stalk conveying belts 10 reach the rice seedling cutting device 13 to ensure that the stalks can be effectively detached, thereby ensuring the continuity of the harvesting process;

[0053] d. The ginger stalks are further aligned and aligned by the aligning and cutting device 9, and the stalks are cut by the cutting device 13;

[0054] e. The cut ginger falls onto the ginger piece collector 8 and is collected in the ginger piece collecting box 7.

[0055] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by adopting existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical solutions of the present invention and are not limitations of the present invention.
